We aimed to determine the economic impact of absenteeism and presenteeism from five conditions potentially comorbid with depressive symptoms—back or neck disorders, depression, anxiety, or emotional disorders, chronic headaches, stomach or bowel disorders, and insomnia—among Japanese workers aged 18–59 yr. Participants from 19 workplaces anonymously completed Stanford Presenteeism Scale questionnaires. Participants identified one primary health condition and determined the resultant performance loss (0–100%) over the previous 4-wk period. We estimated the wage loss by gender, using 10-yr age bands. A total of 6,777 participants undertook the study. Of these, we extracted the data for those in the 18–59 yr age band who chose targeted primary health conditions (males 2,535; females 2,465). The primary health condition identified was back or neck disorders. We found that wage loss due to presenteeism and absenteeism per 100 workers across all 10-yr age bands was high for back or neck disorders. Wage loss per person was relatively high among those identifying depression, anxiety, or emotional disorders. These findings offer insight into developing strategies for workplace interventions on increasing work performance.

We established a homologous sandwich enzyme-linked immunosorbent assay (ELISA) to measure serum levels of canine ferritin. Our assay uses a rabbit anti-canine heart ferritin polyclonal antibody, and canine heart ferritin as a standard. Serum ferritin concentration in healthy dogs (n=163) was 789 ± 284 ng/ml (mean ± standard deviation), a value higher than reported previously. Confidence levels relating to repeatability, dilution, and recovery for this method were high. Therefore, we believe our developed sandwich ELISA will be effective in evaluating serum levels of canine ferritin.

Introduction: Oblique lateral interbody fusion (OLIF) can achieve recovery of lumbar lordosis (LL) in minimally invasive manner. The current study aimed to evaluate the location of lateral intervertebral cages during OLIF in terms of LL correction.Methods: The subjects were patients who underwent OLIF for lumbar degenerative diseases, including lumbar spinal stenosis, spondylolisthesis, and discogenic low back pain. Their clinical outcome was evaluated using visual analogue scale on lower back pain (LBP), leg pain and numbness. The following parameters were retrospectively evaluated on plain radiographic images and computed tomography scans before and at 1 year after OLIF: the intervertebral height, vertebral translation, and sagittal angle. The cage position was defined by equally dividing the caudal endplate into five zones (I to V), and its association with segmental lordosis restoration was analyzed. Subjects were also evaluated for a postoperative endplate injury.Results: Eighty patients (121 fused levels) with lumbar degeneration who underwent OLIF were included. There were no significant specific distribution in preoperative disc pathology such as disc angle, height, and translation. After OLIF, sagittal alignment was improved with an average correction angle of 3.8º at the instrumented segments in a level-independent fashion. All cases showed significant improvement in clinical outcomes, and had improvement in the radiological parameters (P<0.05). A detailed analysis of the cage position showed that the most significant sagittal correction and the most postoperative endplate injuries occurred in the farthest anterior zone (I). Cages with a 12-mm height were associated with more endplate injuries compared with shorter cages (8 or 10 mm).Conclusions: OLIF improves sagittal alignment with an average correction angle of 3.8º at the instrumented segments. We suggest that the optimal cage position for better lordosis correction and the fewest endplate injuries is zone II with a cage height of up to 10 mm.

Recent progress in coded imaging has enabled us to recover sharp images from undesirable image blurs caused by depth and motion. However, the existing methods are limited to single types of blurs, such as depth blur or motion blur. The coded imaging must also tackle the problem of image noise caused by decreasing of input light. In this paper, we propose a method, which enables us to deblur both depth blur and motion blur simultaneously by coding image capture both in space and time. In particular, we show that by changing the aperture pattern efficiently, accurate image deblurring can be achieved under the existence of image noise.

We evaluated the toxicity of tetradecanoic acid methyl ester sodium salt (C14-MES), a major component of fabric detergents, following the test guidelines of the Organization for Economic Cooperation and Development. The rat acute oral LD50 was 1,000 mg/kg in males and 500 mg/kg in females. Applying the combined repeated dose and reproductive/developmental toxicity screening test (ReproTox), we exposed groups of Crj:CD (SD) IGS rats to C14-MES in the diet at concentrations of 0, 0.3, 0.6, or 1.2%. We observed decreases in fibrinogen levels and longer prothrombin time at the 1.2% treated level in females and decreases in serum triglyceride levels in both sexes at the 0.6% and 1.2% treatment levels, but the effects were not clinically significant. The no-observed-effect-level (NOEL) for repeated dose toxicity was 0.3% (175 mg/kg body weight/day for males, 249 for females). The NOEL for reproduction/developmental toxicity was 1.2% (740 mg/kg for males, 1039 for females). C14-MES was negative in the reverse gene mutation assay and the chromosomal aberration test and did not induce skin sensitization in the guinea pig maximization test. These data confirm that C14-MES is of low hazard potential.
