Influences on Participation in Life After Spinal Cord Injury: Qualitative Inquiry Reveals Interaction of Context and Moderators

Background: Greater understanding of the influences on participation in life after spinal cord injury (SCI) can inform rehabilitation theory and practice. Careful qualitative inquiry can reveal subjective meanings associated with the relevant experiences, strategies, and perceptions of those with lived experience of SCI. A search of literature, followed by a thematic synthesis of qualitative studies, was undertaken to bring together these insights in a meaningful way. Methods: The research question guiding the literature review and synthesis was, What do people with SCI perceive to be the influences on their participation in life? Three critical databases were searched for qualitative studies examining influences on participation in life after SCI. Peer-reviewed studies published after 2006, involving adults with SCI living in countries with advanced economies, were included. Data were extracted from 24 articles and subjected to three-level thematic synthesis—the coding of primary data from the studies, the development of descriptive themes based on an organization of those codes, and the generation of analytical themes. Results: The synthesis yielded five analytical themes, supported by 17 descriptive themes. The analytical themes were (1) external contextual influences, (2) personal physical context, (3) personal psychological context, (4) potential moderators of participation outcomes, and (5) temporal dimensions of participating in life after SCI. Interpretation: These themes highlight the complex interactions that shape participation from the perspective of people with SCI. Closer examination of the potential moderators may provide insights into effective rehabilitation interventions. Conclusions: Synthesis of qualitative inquiry provides valuable insights into the perceptions of influences on participation in life from the point of view of people with SCI. The findings of this synthesis are instructive for rehabilitation theory and practice. It can complement what we learn from using the ICF to understand participatio

The chemical potential of the electron gas on a one dimensional lattice

The chemical potential of the electron gas on a one-dimensional lattice is determined within the discrete Hubbard model. The result will have applications in studies of transport properties of quasi one-dimensional organic conductors such as the Bechgaard salts.Comment: 4 pages,plain TeX,presented at the 9 National Congress of Yugoslav Physicists,held in May 1995.,and published in the proceedings.The author can be contacted at: [email protected]

Prognos (R) in the diagnosis of amalgam hypersensitivity - A diagnostic case-control study

Objective: We aimed to investigate whether the Prognos (R) device might be a useful tool in the diagnosis of disorders suspected to be due to dental amalgam fillings. Participants and Methods: A diagnostic case-control study was performed in 27 patients who complained about health problems attributed to amalgam ( cases), 27 healthy volunteers with amalgam fillings ( controls I), and 27 healthy amalgam-free volunteers ( controls II). All participants were tested before and after application of 300 mg DMPS (2.3-dimercapto-1-propanesulfonic acid) with Prognos, a diagnostic device for the energetic measurement of Traditional Chinese Medicine meridians. In addition, mercury was measured in blood, urine, and saliva, and a lymphocyte transformation test (LTT) was performed. Results: Diagnoses derived from the first and second Prognos testing did not agree above chance (Cohen's Kappa = -0.11, 95% confidence interval -0.33 to 0.10; p = 0.30). Agreement for secondary outcome measures was poor, too. Prognos measurements did not differ between cases and controls. Correlations with measurements in urine, blood and saliva were low. Conclusion: In this study Prognos could not be shown to be a useful tool in the diagnosis of disorders suspected to be due to dental amalgam fillings

Cutaneous Brucellosis unmasked as Aureimonas altamirensis in a wound culture

Aureimonas altamirensis was isolated from a wound culture and initially misidentified as Brucella melitensis by the VITEK® 2 system. The VITEK-MS did not provide identification whereas the Bruker MALDI-ToF MS system and 16-S sequencing revealed a clear identification, which highlights the importance of inclusion of species in databases for accurate and fast identification of bacteria

Longitudinal effects of time since injury and age at injury on outcomes of people with spinal cord injury in Queensland, Australia

Study design: Longitudinal cohort study. Objectives: To investigate the longitudinal effects of time since injury and age at injury on outcomes of quality of life, physical function, secondary conditions and participation, in people with traumatic spinal cord injury (SCI). Setting: Community resident people with spinal cord injury in Queensland, Australia. Methods: A baseline sample of 270 people with SCI was recruited. Telephone surveys on measures of quality of life (WHOQOL-Bref), secondary conditions (Secondary Conditions Surveillance Instrument, subset), physical functioning (Functional Independence Measure motor subscale) and participation (Community Integration Measure) were conducted each year between 2004 and 2008, and again in 2018. Random-effect within-between models were used to determine the effect of time since injury and age at injury on each outcome variable. Inverse probability-of-censoring weights were used to correct for selection bias. Results: There was an effect of time since injury on secondary conditions, with a one-year change associated with 9% higher odds of having worse Secondary Conditions Surveillance Instrument scores (odds ratio = 1.09, 95% confidence interval = 1.02, 1.17; p = 0.006). We did not find any evidence of a time since injury effect on quality of life, physical function, or participation. Similarly, we did not find any evidence of an age at injury effect on any outcome variable. Conclusions: Secondary conditions may increase with longer time since injury among people with SCI, suggesting appropriate formal and informal supports are required to minimise the impact of these emerging health problems as individuals age

Dental amalgam fillings: An under-investigated source of mercury exposure

Dental amalgam fillings, which contain about 50% mercury, have been used since the early 19th century. However, their use has been controversial, particularly because they continually release small amounts of mercury. Inorganic mercury is known to be highly toxic, particularly to the nervous system and kidneys, but exposures from amalgam fillings are generally well below those established as toxic. However, uncertainties about threshold concentrations of effect and the nature of any long-term exposure effects remain. Considering the long-standing and widespread use of these fillings, there has been remarkably little investigation of their safety and most epidemiologic studies have been relatively recent. In general, investigations to date have shown little evidence of effects on general chronic disease incidence or mortality. There have been few studies so far of neurodegenerative diseases and results have been equivocal. Assessments of the safety of dental amalgam have mainly been based on studies of occupationally exposed populations. However, the amalgam-exposed population contains a broader, potentially more susceptible, spectrum of people. In that regard, a number of studies of children that have found no evidence of health effects have provided some reassurance
