The Risk Factor of Worsening Low Back Pain in Older Adults Living in a Local Area of Japan: The GAINA Study

Background: Several factors, particularly osteoporosis, obesity, and a lack of exercise, contribute to low back pain (LBP). This observational longitudinal cohort study to identify the risk factors for worsening low back pain. Methods: We sent a self-administered questionnaire and a consent form for this study to 1,450 subjects aged > 40 years in Hino, Japan. Baseline assessments of 273 individuals undergoing medical check-ups were conducted from 2014 to 2016. The subjects were divided into Group A (no change or improvement in LBP) and Group B (worsening LBP). LBP was assessed using a visual analog scale; body mass index (BMI), bone mineral density, skeletal muscle index (SMI), standing posture, and habitual exercise frequency were also evaluated. We defined, habitual exercise as nontherapeutic exercise (e.g. swimming, walking, physical exercise and work out). Results: Overall, 81.2% subjects performed habitual exercise in Group A, a greater number of subjects than the 40.8% in Group B. BMI, SMI, and bone mineral density (BMD) were not significantly different between the two groups. Lack of exercise was a significant risk factor for worsening of LBP. On the other hand, the lack of osteoporosis treatment was significantly different between subjects with worsening LBP despite habitual exercise and those who did not perform habitual exercise. Conclusion: Although habitual exercise is useful to prevent LBP, it may not necessarily be useful for those with a lack of osteoporosis treatment. Although exercise is typically posited to prevent LBP, it may not be effective in preventing LBP associated with osteoporosis.journal articl

Development of Dose Evaluation Technology using PVA-KI Gel Dosimeter

Cancer treatment using radiation, which has less impact on the human body, will play an increasingly important role in Japan in the super-aged society. Therefore, in cancer treatment using radiation, visualization of radiation strength and distribution is an essential technique for accurate evaluation of dose distribution. Chemical dosimeters have been researched and developed at various research institutes, but have not been put into practical use due to issues such as chemical sensitivity, safety, cost and processing. In this laboratory, we developed a low-cost PVA-KI gel dosimeter (hereinafter PVA-KI gel) that can be manufactured at low cost using a PVA (polyvinyl alcohol) aqueous solution with a KI (potassium iodide) added component. Currently, UV-visible spectrophotometer is used for measurement of PVA-KI gel which requires expensive equipment and cannot easily provide dode distribution. In order to use PVA-KI gel that can be manufactured at low cost widely, development of a photometric measurement device specialized for PVA-KI gel is desired. In this study, we developed gel analysis software using a measuring device combining an organic EL panel and a digital camera in Visual Basic, to develop a system that can measure the absorbed dose of X-ray irradiation to PVA-KI gel.departmental bulletin pape

Dynamic latent trait models with mixed hidden Markov structure for mixed longitudinal outcomes

<div><p>We propose a general Bayesian joint modeling approach to model mixed longitudinal outcomes from the exponential family for taking into account any differential misclassification that may exist among categorical outcomes. Under this framework, outcomes observed without measurement error are related to latent trait variables through generalized linear mixed effect models. The misclassified outcomes are related to the latent class variables, which represent unobserved real states, using mixed hidden Markov models (MHMMs). In addition to enabling the estimation of parameters in prevalence, transition and misclassification probabilities, MHMMs capture cluster level heterogeneity. A transition modeling structure allows the latent trait and latent class variables to depend on observed predictors at the same time period and also on latent trait and latent class variables at previous time periods for each individual. Simulation studies are conducted to make comparisons with traditional models in order to illustrate the gains from the proposed approach. The new approach is applied to data from the Southern California Children Health Study to jointly model questionnaire-based asthma state and multiple lung function measurements in order to gain better insight about the underlying biological mechanism that governs the inter-relationship between asthma state and lung function development.</p></div
