抄録 To clarify the relationship between dose-volume histogram (DVH) parameters and radiation pneumonitis (RP) after surgery in cases of non-small cell lung cancer (NSCLC) treated with induction concurrent chemoradiotherapy (CCRT). Patients with NSCLC treated with induction CCRT (chemotherapy: cisplatin and docetaxel; radiotherapy: 2.0 Gy fractions once daily for a total of 46 Gy) before surgery were reviewed. We calculated the percentage of lung volume receiving at least 20 Gy (V20) and the mean lung dose (MLD) for the total lung volume and the lung remaining after resection. Factors affecting the incidence of RP at grade 2 or higher (≥ G2 RP) were analyzed. Eighteen of 49 patients (37%) experienced ≥G2 RP. The V20 and MLD for the lung remaining after resection (V20r and MLDr) were significant predictors according to the multivariate analysis (p=0.007 and 0.041, respectively). The incidence of ≥G2 RP was 8% in patients with V20r<10%, and 13% in patients with MLDr<5.6 Gy, respectively. The optimal approach to reduce the rate of postoperative RP in patients with induction CCRT for NSCLC is to keep the V20r below 10% and/or the MLDr below 5.6 Gy in the radiotherapy planning.

抄録 We investigated variances in the stability and amount of postoperative exodrift among age groups of intermittent exotropia (XPT) patients who underwent unilateral lateral rectus muscle recession and medial rectus muscle resection. We analyzed the cases of 110 consecutive patients who underwent the surgery in 2004-2011, dividing the patients into groups by their age at surgery: <10, 10-19, and ≥20 years. We performed a regression analysis (dependent variable: postoperative exodrift (°); independent variable: number of days post-surgery) using the formula of curve lines. When the tangent line slope was = 0.01 (°/days) for each group, we defined the numbers of days until alignment became stable as the ‘stable days.’ We evaluated the between-group differences in the amount of exodrift calculated for the stable days. The coefficients and coefficients of determination for the fitting curves were: <10 year group: f(x)=12.2 (1−e−0.0183x) (r2=0.588, p<0.05); 10-19 year group: f(x)=10.0 (1−e−0.0178x) (r2=0.453, p<0.05); ≥20 year group: f(x)=3.40 (1−e−0.0382x) (r2=0.217, p<0.05). There were 389 , 388, and 153 stable days, and the estimated postoperative exodrift with long-term follow-up was 11.5±3.7°, 9.3±4.4°, and 4.1±3.6° for the < 10 year, 10-19 year, and ≥ 20 year groups, respectively (≥20 year vs. other 2 groups, p<0.05). Longer periods and more postoperative exodrift were associated with younger age at surgery. The postoperative evaluation was approx. ≥ 1 year post-surgery in patients aged < 20. These findings may contribute to evaluating XPT’s success rate and prognoses.

抄録 We used image-processing software to analyze the setup errors at the skin surface position of breast cancer patients (n=66) who underwent post-operative whole breast irradiation at our hospital in 2014-2015. The sixty-six digital reconstructed radiographs (DRR) were created at the treatment planning for each patient. The lineacgraphies (n=377) were taken after the patients’ setup during radiotherapy. The lineacgraphies and DRR were superimposed at the skin surface position for each patient with the image-processing software. We measured the deviations of the isocenters for the nipple-lung (X) direction and craniocaudal (Y) direction and the deviation of the rotation angle of the XY axes between the lineacgraphy and DRR on the superimposed images. The systematic error (μ, Σ) and random error (σ) were calculated from the X and Y deviations and rotation angle deviation. The μ of X, Y, and rotation angle were 0.01 mm, −1.2 mm, and 0.05°, respectively. The Σ of X, Y, and rotation angle were 1.8 mm, 1.5 mm, and 0.9°, respectively. The σ of X, Y, and rotation angle were 2.0 mm, 1.5 mm, and 1.0°, respectively. Our analyses thus revealed that evaluations using image-processing software at the skin surface position in routine breast radiotherapy result in sufficiently small setup errors.

抄録 We validated a navigator-echo-triggered sequence that drives magnetization before cardiac-gated inversion recovery T1 turbo field echo acquisition, in the sedated free-breathing pediatric population. Cardiac magnetic resonance imaging was performed on sedated infants with single ventricle. We calculated the signal-to-noise ratios and contrast-to-noise ratios of 2 groups of images obtained using respiratory triggering with and without navigator echo. All images were then visually assessed by 2 observers. The signal-to-noise ratio and the contrast-to-noise ratio were significantly higher with than without navigator echo (p<0.01; p<0.05). The visual assessment scores were also consistently better with than without navigator echo (p<0.01). Free-breathing navigator echo was found to have the advantage of decreasing the motion artifact caused by respiration. Cardiacgated inversion recovery T1 turbo field echo sequence for free-breathing navigator-echo-triggered respiration allows for the acquisition, in sedated infants, of diagnostic images whose quality exceeds that of the non-navigator-echo-triggered alternative.

抄録 We devised biomathematics-based formulae to estimate the standard values of fetal growth of Japanese after 22 weeks' gestation. The growth rates of bi-parietal diameter (BPD), abdominal circumference (AC), femur length (FL), and estimated fetal body weight (EFBW) at the time of gestation were assumed to be proportional to the product of the value at the time and the rest value of an unknown maximum value, respectively. The EFBW was also assumed to follow a multiple logistic function of BPD, AC and FL to fit the standard values of Japanese fetuses published by the Japan Society of Ultrasonics in Medicine. The Mann-Whitney test was used for statistical analysis. The values as a function of gestational day, t, were as follows: BPD(t)=99.6/(1+exp (2.725−0.01837*t)) (mm); AC(t)=39.7/(1+exp (2.454−0.01379*t)) (cm); FL(t)=79.6/(1+exp (2.851−0.01710*t)) (mm); EFBW(t)=8045.1/(1+exp (6.028−0.06582*BPD(t)−0.1469*AC(t)+ 0.07377*FL(t))) (g). EFBW as a function of BPD, AC and FL was as follows: EFBW=8045.1/(1+exp (4.747+ 0.02584*BPD+0.1010*AC−0.1416*FL)) (g). When the BPD, AC and FL were at −2 standard deviation (SD), −1SD, mean and + 2SD, the EFBW values calculated by the formula were statistically closer to the standard values than conventional formulas with p-values of 4.871×10−7, 4.228×10−7, 9.777×10−7 and 0.028, respectively. The formulae based on biomathematics might be useful to estimate the fetal growth standard values.

抄録 The effect of skeletal muscle mass (SMM) on the outcomes of sorafenib treatment for hepatocellular carcinoma (HCC) has not been established. We measured the SMM in HCC patients treated with sorafenib, evaluated the patients’ survival, and evaluated the association between skeletal muscle depletion and sorafenib treatment. Of the 97 HCC patients treated with sorafenib at our institution in the period from July 2009 to February 2015, our study included 69 patients (51 males, 18 females) who had received sorafenib for ≥ 8 weeks and whose follow-up data were available. SMM was calculated from computed tomography images at the mid-L3 level (cm2) and normalized to height (m2) to yield the L3 skeletal muscle index (L3-SMI, cm2/m2). The median L3-SMI value was higher in the males (43 cm2/m2) compared to the females (36 cm2/m2). In the males only, the multivariate Cox regression identified an L3-SMI <43 cm2/m2 as independently associated with higher mortality compared to an L3-SMI ≥43 cm2/m2 (hazard ratio 2.315, 95% confidence interval: 1.125-4.765, p=0.023). Skeletal muscle depletion is a factor predicting poor prognosis for male patients with advanced HCC treated with sorafenib.

抄録 We evaluated how exposure to airborne volatile organic compounds emitted from a plastic recycling facility affected nearby residents, in a cross-sectional study. Individuals>10 years old were randomly sampled from 50 households at five sites and given questionnaires to complete. We categorized the subjects by distance from the recycling facility and used this as a proxy measure for pollutant exposure. We sought to improve on a preceding study by generating new findings, improving methods for questionnaire distribution and collection, and refining site selection. We calculated the odds of residents living 500 or 900 m away from the facility reporting mucocutaneous and respiratory symptoms using a reference group of residents 2,800 m away. Self-reported nasal congestion (odds ratio=3.0, 95% confidence interval=1.02-8.8), eczema (5.1, 1.1-22.9), and sore throat (3.9, 1.1-14.1) were significantly higher among residents 500 m from the facility. Those 900 m away were also considerably more likely to report experiencing eczema (4.6, 1.4-14.9). Air pollution was found responsible for significantly increased reports of mucocutaneous and respiratory symptoms among nearby residents. Our findings confirm the effects of pollutants emitted from recycling facilities on residents’ health and clarify that study design differences did not affect the results.
