Abstract
PURPOSE/OBJECTIVE(S) In pancreatic cancer, a tumor is surrounded by the gastrointestinal (GI) tract, which is subject to changes in location, shape, and contents. Due to these inter-fractional changes, proton beam therapy (PBT) for pancreatic cancer may result in unintentionally high doses to the GI tract. Daily adaptive re-planning can solve this problem, but is not yet established with PBT due to its resource intensive characteristics. This study aims to evaluate the GI tract dose using weekly computed tomography (CTw) and the possibility of dose realignment adaptation by shifting the isocenter (IC) of the PBT plan, which does not require re-planning. MATERIALS/METHODS We retrospectively analyzed 6 consecutive patients with unresectable pancreatic cancer treated with real-time-image gated PBT using a fiducial marker. The planning CT was scanned at the natural expiration of respiration and a PBT plan of 60 GyE in 25 fractions (baseline plan, PLANbase) was created. The CTw images were acquired the day before start of PBT and once a week during the PBT course thereafter. The PLANbase was rigidly transferred to the CTw based on the relationship between the three-dimensional coordinates of the fiducial marker and those of the IC in the PLANbase. The PLANeval was created by recalculating the PLANbase on the CTw. We evaluated the doses to the stomach, duodenum, and intestines in the PLANeval according to the following criteria: Dmax of the stomach < 60 GyE, duodenum and intestines < 55 GyE, and D1cc of the stomach < 55 GyE, duodenum and intestines < 54 GyE. In addition, we investigated the GI tract dose realignment adaptation for the PLANeval with its IC shifted 2mm, 4mm, and 6mm in each of 6 directions (right, left, ventral, dorsal, cranial, and caudal), respectively. RESULTS A total of 35 PLANeval were created for the CTw. In the PLANbase of the 6 patients, the average of Dmax and D1cc of the stomach, duodenum and intestines were 50.7 GyE (range, 46.7-53.6) and 50.0 GyE (45.0-53.2), 49.2 GyE (44.3-51.7) and 48.8 GyE (43.7-51.5), and 49.2 GyE (44.8-52.0) and 48.9 GyE (44.6-51.8), respectively. In the PLANeval, the average of Dmax and D1cc of the stomach, duodenum, and intestines were 53.3GyE (43.8-61.4) and 52.8 GyE (43.2-61.1), 51.0 GyE (36.1-60.0) and 50.3 GyE (35.4-59.8), and 52.5 GyE (36.6-61.0) and 51.9 (34.4-60.9) GyE, respectively. Twenty-two of the 35 PLANeval (63 %) did not meet at least one of the GI tract dose criteria. In 11 of 22 PLANeval with higher doses to the GI tract, the IC shift resulted in GI dose reductions and all dose criteria were met. The minimum amount of the IC shift required to meet the criteria was 2 mm for 8 plans and 4 mm for 3 plans. The remaining 11 PLANeval did not meet the criteria using dose realignment adaptation by shifting the isocenter. CONCLUSION Adaptive replanning is necessary for PBT for pancreatic cancers due to excessive GI tract doses in more than 60% of the plans. Dose realignment adaptation by shifting the IC, which does not require re-planning, may be an option in adaptive treatment strategies.

Abstract
PURPOSE/OBJECTIVE(S) In pancreatic cancer, radiation induced lymphopenia (RIL) is associated with a poor prognosis. However, normal tissue complication probability (NTCP) models predicting RIL in pancreatic cancer treated with concurrent chemoradiotherapy (CCRT) have yet to be developed. This study aims to develop a least absolute shrinkage and selection operator (LASSO)-based multivariate NTCP model to predict severe RIL in patients with pancreatic cancer during CCRT and to validate the model internally. MATERIALS/METHODS We retrospectively reviewed patients with localized pancreatic cancer who underwent CCRT using three-dimensional conformal radiation therapy from 2013 to 2021. The exclusion criteria were patients with distant metastasis; patients who did not complete RT due to tumor progression; patients who did not have absolute lymphocyte count (ALC) data available before or during RT. An ALC of < 0.5 K/μL during CCRT was defined as severe RIL. A NTCP model of severe RIL was developed by LASSO-based multivariate analysis. We used age, sex, Karnofsky performance status, maximum tumor size, carbohydrate antigen 19-9 level before RT, ALC before RT, volume of planning target volume (PTV), and dosimetric parameters for surrounding organs (including spleen, vertebrae, liver, bilateral kidneys, gastrointestinal tracts) as variables for LASSO. In addition, internal validation was performed by the bootstrap method. The predictive performance of the model was evaluated by the area under the curve (AUC) of the receiver operating characteristic curve and scaled Brier score. RESULTS Of the 131 patients included in the study, the median age was 68 years (range, 42-84), and 55% were male. The median ALC before RT was 1.37 K/µL (0.52-3.50). The median PTV volume was 315.4 ml (86.3-1079.3). The median dose of radiotherapy was 50.4 Gy (16.2-50.4), with 1.8 Gy per fraction. Combination chemotherapy was S-1 in 99 cases (75.6%) and gemcitabine in 32 cases (24.4%). Induction chemotherapy before CCRT was performed in 39 patients (29.8%). Severe RIL was observed in 84 (63.6%) patients. The LASSO showed that low baseline ALC (p = 0.0002), large PTV volume (p < 0.0001), and a large kidney V5 defined as the percentage of bilateral kidneys receiving 5 Gy or more (p = 0.0338) were selected as parameters of the prediction model for severe RIL (AUC = 0.917) and scaled Brier score was 0.511. As a result of internal validation by the bootstrap method, the average AUC was 0.918 (95% confidence interval, 0.849-0.954). CONCLUSION Severe RIL occurred frequently during CCRT for pancreatic cancer, and a NTCP model for severe RIL developed and validated internally in this study showed good predictive performance. External validation is needed before this NTCP model can be used as a benchmark for treatment planning to reduce the risk of severe RIL and for considering future treatment approaches.

Abstract
This study demonstrates a high-slew-rate 5-kV pulse generator for electrical insulation tests. Electrical equipment, such as electrical actuators and traction drive motors, are exposed to severe electrical stress because recent switching inverters have high-frequency outputs with high supply voltages using wide-bandgap power devices. For an advanced electrical insulation test, a high-voltage pulse generator is required with a high slew rate; however, such generators suffer from large switching noise, followed by measurement noise, such as ground voltage fluctuations and radiation noise, hindering the detection of partial discharge (PD) phenomena. In this study, we propose a 5-kV pulse generator based on series-connected 1700-V silicon carbide (SiC) metal-oxide-semiconductor field-effect transistors (MOSFETs). Four 1700-V SiC MOSFETs are connected in series as a 5-kV SiC switching module, constituting a half-bridge configuration for the pulse generator. The obtained switching waveforms exhibit fast rise times of 48 ns under 5 kV and 6.2 ns under 400 V with a low voltage overshoot and ringing owing to superior device characteristics and reduced parasitic inductances. Because of the low switching noise, we detect a clear PD signal with a 1500-V pulse when using the fabricated pulse generator for a PD test of a twisted pair. The proposed pulse generator uses a hard switching configuration such that the pulse generator can vary the pulse width from 150 ns to DC and increase the switching pulse cycle beyond 1 MHz by changing the control signals of the SiC MOSFETs.

Abstract
Abstract
Background
Currently, cryoballoon ablation (CBA) has proven to be highly effective in achieving free from atrial fibrillation (AF), especially paroxysmal AF. However, the optimal freezing protocol for each patient to achieve successful pulmonary vein isolation by only CBA is still uncertain. The aim of this study was to evaluate the clinical implications of a reduction in the freezing duration (<180s) during CBA guided by the time to target temperature.
Methods
From November 2015 to August 2018, 286 consecutive paroxysmal AF patients undergoing CBA were enrolled. We compared 107 patients undergoing a tailor-made CBA procedure (Group A; August 2017-August 2018) to 179 patients with a standard CBA procedure (Group B; November 2015–July 2017). In Group A, the freezing duration was reduced to 150s when the temperature reached ≤−40°C within 40s. Furthermore, we reduced it to 120s when it reached ≤−50°C within 60s. In the other patients, the freezing time was 180s except for excessive freezing over −60°C and/or emergent situations while monitoring the esophageal temperature and for phrenic nerve injury as in Group B.
Results
The baseline clinical characteristics were similar between two groups. In Group A, 89 patients (83%) underwent CBA with a reduction in the freezing time. The rate of having reduction time in left inferior PV (LIPV) and right inferior PV (RIPV) was lower compared with left superior PV (LSPV) and right superior PV (RSPV) (respectively 17%, 29%, 56%, and 63.5%). However, for right inferior PV, in 31 patients having the reduced freezing time, none of them required touch-up ablation. Although the procedure time and frequency of touch-up ablation did not differ between the 2 groups, total freezing time for each PV was significantly shorter in Group A than Group B as shown in figure (LSPV: 164±28s vs. 216±67s; p<0.001, LIPV: 187±44s vs. 218±69s; p<0.001, RSPV: 147±31s vs. 192±51s; p<0.001, RIPV: 180±50 vs. 218±73s; p<0.001). The AF free survival rate during the follow-up period (356±167 days) was similar between the 2 groups (log-rank test, p=0.38). Furthermore, the complication rate was similar 2 groups.
The freezing time for each PV
Conclusion
The safety and efficacy of the new tailor-made CBA strategy were non-inferior to the standard procedure. This study showed that the unnecessary freezing time could be reduced in most of paroxysmal AF patients.

Abstract
Abstract
Background
Drug-eluting stent restenosis (DES-ISR) is associated with poorer outcomes than those of bare-metal stent restenosis after treatment with paclitaxel-coated balloon (PCB), and late restenosis after PCB angioplasty for DES-ISR is a residual problem. Excimer laser coronary angioplasty (ELCA) is thought to be advantageous for ISR treatment by removing neointima. However, whether the combination of ELCA and PCB angioplasty is more effective than the use of PCB only angioplasty in DES-ISR has not been studied so far.
Purpose
We evaluated the efficacy of ELCA and PCB combination therapy for DES-ISR at mid-and late-term after revascularization.
Methods
From January 2014 to March 2016, 166 DES-ISR lesions were treated with ELCA and no-ELCA prior to PCB. Two serial angiographic follow-ups were planned for the patients (at 6–12 and 18–24 months after procedure). Acute procedural and follow-up angiographic results were assessed by quantitative coronary angiography. ELCA and no-ELCA group included 74 lesions and 92 lesions, respectively.
Results
There was no significant difference between the two groups in the clinical characteristics except the prevalence of hemodialysis, the rate of first-generation DES (37.9% vs 36.8%, p=0.897), previous stent size (2.90±0.39 mm vs 2.77±0.39 mm, p=0.063), and reference vessel diameter (2.65±0.46 mm vs 2.60±0.65 mm, p=0.593). Early follow-up angiography was performed in 66 lesions (89.1%) of ELCA group, and was done in 76 lesions (82.6%) of no-ELCA group. In the ELCA group, percentage diameter stenosis (%DS) just after procedure and at 6–12 months later were significantly smaller than those of no-ELCA group. Besides, target lesion revascularization (TLR) rate at 6–12 months after procedure was tended to be lower in the ELCA group. Late follow-up angiography was performed for 93 lesions (81.6%) of the remaining 114 lesions (excluding TLR lesion), late restenosis was found 9 lesions (18.6%) in the ELCA group and 11 lesions (24.4%) in the no-ELCA group (p=0.504). Late luminal loss was similar in both groups (0.37±0.71 mm vs 0.24±0.82 mm, p=0.438), and %DS at 12–18 months after revascularization was not different between the two groups.
Changes of %DS and TLR rate
Conclusions
%DS in the ELCA group was smaller at just after procedure and the advantage was kept even after 1-year. However, late restenosis and TLR at 2-year after revascularization for DES-ISR could not be reduced by ELCA and PCB combination therapy.

Abstract
The existence of a spatially varying texture in superfluid ^{3}He is a direct manifestation of the complex macroscopic wave function. The real space shape of the texture, namely, a macroscopic wave function, has been studied extensively with the help of theoretical modeling but has never been directly observed experimentally with spatial resolution. We have succeeded in visualizing the texture by a specialized magnetic resonance imaging. With this new technology, we have discovered that the macroscopic chiral domains, of which sizes are as large as 1 mm, and corresponding chiral domain walls exist rather stably in ^{3}He-A film at temperatures far below the transition temperature.

Abstract
Anorexia nervosa (AN) is a psychiatric disorder, in which the prognosis for some patients is poor. The etiology and effective treatments for AN have not been established. We examined morphometric changes in the brain of AN and clarified how the changes were associated with symptoms and pathophysiology. We enrolled 52 participants: 7 with the restrictive type of AN, 13 with the binge-eating/purging type, 3 with eating disorder not otherwise specified, and 29 healthy controls. Participants underwent T1-weighted MRI. Group differences between patients and controls in gray matter volume (GMV) were analyzed using voxel-based morphometry. Age and body mass index (BMI) were considered covariates. Correlations between regional GMVs and drive for thinness and body dissatisfaction were examined. Patients had decreased GMV in the superior/middle temporal gyrus (STG/MTG), pulvinar, and superior frontal gyrus after correction for age and BMI, and in the STG/MTG, middle frontal gyrus, and cingulate after correction for age. A correlational group difference was detected for body dissatisfaction and GMV in the STG. Our findings suggest that decreased GMV in the STG is related to body dissatisfaction that could come from impaired visuospatial perception, together with GMV decreases in several regions, which may be involved in development of AN.

Abstract
BACKGROUND There are few previous reports regarding the cause and evolution of liver injury in patients with anorexia nervosa (AN) during the refeeding process, and its management remains controversial. This study aimed to determine the risk factors for elevated liver enzymes during refeeding and their effect on the therapeutic process in severely malnourished patients with eating disorders. METHODS In a retrospective cohort study of 167 female inpatients in a single hospital from January 2004 to March 2015, 67 who had normal alanine aminotransferase (ALT) levels on admission were divided into two groups according to the presence or absence of elevated ALT levels during refeeding, and then compared. RESULTS The median age and body mass index (BMI) of the patients on admission were 22 [interquartile range (IQR), 16-33] years and 12.2 (IQR, 11.1-13.0) kg/m2, respectively. Compared with their cohorts, significantly more patients in the early onset age group (<15 years old) had elevated ALT levels during refeeding (67% vs. 33%, p = 0.033), as did patients with longer median time to nadir BMI (3.0 vs. 0 days, p = 0.03). In addition, onset age [odds ratio (OR): 0.274; 95% confidence interval (CI): 0.077-0.981; p = 0.047] and time to nadir BMI (OR: 1.271; 95% CI: 1.035-1.56; p = 0.022) were significantly associated with the odds of elevated ALT levels during refeeding. CONCLUSIONS The results of this study suggest that early age at onset may be a potential risk factor for elevated ALT levels during refeeding in severely malnourished patients with eating disorders. Furthermore, elevated ALT levels during refeeding were significantly associated with delay in the start of weight gain. No significant relationship was found between the amount of initial prescribed calories and elevated ALT levels during refeeding. The median time to maximum ALT was 27 (IQR, 21-38) days after the refeeding process started.

Abstract
The authors investigated the association between personality and physical/mental status in malnourished patients with eating disorders. A total of 45 patients with anorexia nervosa, avoidant/restrictive food intake disorder, and other specified feeding or eating disorders were included and compared with 39 healthy controls. Personality characteristics and severity of depression were assessed using the Temperament and Character Inventory-125 and Beck's Depression Inventory. Depression correlated with harm avoidance and self-directedness in both cases and controls. Body mass index did not correlate with personality in either group. These findings should be verified by longitudinal studies with higher weight/weight recovered patients.

Abstract
To break the vicious circle between malnutrition and severe infection which has been linked to the great magnitude of infant deaths worldwide, we have been searching by means of clinical and experimental studies for measures which provide for rapid enhancement of body defenses. Based on clinical observations of malnourished children and the sequence of recovery during nutritional rehabilitation, it is suggested that the complement system is a more important factor during the early stage of nutritional recovery than CMI. In animal experiments using malnourished rats, nutritional deprivation affected various components of the body defense system to various extents, CMI being the most susceptible to influence. The complement system acted to maintain host defense even when CMI was impaired. Also observed was the earlier recovery of serum complement to normal or higher levels as compared with that of CMI. The complement system responded to bacterial infection much earlier than other immunologic responses, even in malnourished rats with depressed CMI. The infected rats showed a much higher rate of de novo synthesis of complement proteins than noninfected rats, and this effect was predominant in the malnourished group. Based on these animal experiments, we attempted to induce rapid heightened resistance to infection in malnourished rats by enhancing the complement system. After administration of proper doses of lentinan or Zn-chlorophyllin, which are known to activate C3 in vitro, to malnourished rats, heightened resistance against bacterial infection was induced together with a heightened complement response. In contrast, after administration of cobra venom factor, which is known to reduce C3 activity both in vitro and in vivo, resistance against bacterial infection was reduced, even in well-nourished rats. In summary, we have analyzed in the malnourished state the mechanism of heightened resistance against bacterial infection after activation of C3 by lentinan or Zn-chlorophyllin. These C3 activators enhanced C3b formation and iC3b formation in vivo, eventually resulting in enhanced interaction of iC3b present on invaders with CR3 on phagocytic cells.

Abstract
Approximately 20% of Beckwith-Wiedemann syndrome (BWS) cases are caused by mosaic paternal uniparental disomy of chromosome 11 (pUPD11). Although pUPD11 is usually limited to the short arm of chromosome 11, a small minority of BWS cases show genome-wide mosaic pUPD (GWpUPD). These patients show variable clinical features depending on mosaic ratio, imprinting status of other chromosomes, and paternally inherited recessive mutations. To date, there have been no reports of a mosaic GWpUPD patient with an autosomal recessive disease caused by a paternally inherited recessive mutation. Here, we describe a patient concurrently showing the clinical features of BWS and autosomal recessive cystinuria. Genetic analyses revealed that the patient has mosaic GWpUPD and an inherited paternal homozygous mutation in SLC7A9. This is the first report indicating that a paternally inherited recessive mutation can cause an autosomal recessive disease in cases of GWpUPD mosaicism. Investigation into recessive mutations and the dysregulation of imprinting domains is critical in understanding precise clinical conditions of patients with mosaic GWpUPD.

Abstract
BACKGROUND Functional neuroimaging techniques are widely used to elucidate changes in brain activity, and various questionnaires are used to investigate psychopathological features in patients with eating disorders (ED). It is well known that social skills and interpersonal difficulties are strongly associated with the psychopathology of patients with ED. However, few studies have examined the association between brain activity and social relationships in patients with ED, particularly in patients with extremely low body weight. METHODS In this study, 22-channel near-infrared spectroscopy was used to quantify regional hemodynamic changes during a letter fluency task (LFT) in 20 female patients with ED with a mean body mass index of 14.0 kg/m(2) and 31 female controls (CTLs). Symptoms were assessed using the Eating Disorder Inventory-2 and Beck Depression Inventory. We hypothesized that frontal activity in patients with ED would be lower than in CTLs and would show different correlations with psychopathological features compared with CTLs. RESULTS The LFT performance and score on the social insecurity subscale of the Eating Disorder Inventory-2 were significantly higher in the ED group than in the CTL group. The mean change in oxygenated hemoglobin (oxy-Hb) in bilateral frontal regions during the LFT was significantly smaller in the ED group than in the CTL group. Social insecurity score was positively correlated with the concentration of oxy-Hb in the bilateral orbitofrontal cortex in the ED group but not in the CTL group. CONCLUSIONS These results suggest that activity of the orbitofrontal cortex is associated with social insecurity and disturbed in patients with ED. Therefore, disturbed orbitofrontal cortex activity may underlie the lack of insight and social isolation that is characteristic of patients with ED.

Abstract
Abstract The SCID mouse model for rheumatoid arthritis (RA) is an established and reliable approach to examining the distinct mechanisms operative in RA synovium, and evaluating novel gene therapy strategies. However, serum concentrations of circulating gene therapy products following gene transfer are frequently too low to allow detection. This problem stimulated us to develop a novel implantation technique to improve the yield of these soluble gene products. Synovial fibroblasts from patients with RA were cultured, passaged, and transduced with Ad5 sTNFRp55:Ig. sTNFRp55:Ig production was confirmed by ELISA, and then cells were implanted into SCID mice using a novel implantation strategy in which pieces of human cartilage were engrafted into a fibroblast-saturated inert sponge. Thereafter, the sponges were implanted under the skin of the mice instead of under the kidney capsule, as in the original approach, allowing co-implantation of larger pieces of cartilage together with higher numbers of adenovirus-transduced RA synovial fibroblasts. The improved implantation technique not only resulted in a reduction in the number of mice needed in each experiment by approximately 60%, and a reduction of the time taken for surgery by about 50%, but also considerably enhanced the serum concentrations of the gene product sTNFRp55-Ig, allowing detection of the soluble TNF receptor p55 by standard ELISA. In summary, the improved implantation technique for the SCID mouse model for RA results in more economic animal treatment, and facilitates the detection and quantification of circulating gene products following adenovirus-based gene transfer into synovial fibroblasts.

Abstract
The IGF2/H19-imprinting control region (ICR1) functions as an insulator to methylation-sensitive binding of CTCF protein, and regulates imprinted expression of IGF2 and H19 in a parental origin-specific manner. ICR1 methylation defects cause abnormal expression of imprinted genes, leading to Beckwith-Wiedemann syndrome (BWS) or Silver-Russell syndrome (SRS). Not only ICR1 microdeletions involving the CTCF-binding site, but also point mutations and a small deletion of the OCT-binding site have been shown to trigger methylation defects in BWS. Here, mutational analysis of ICR1 in 11 BWS and 12 SRS patients with ICR1 methylation defects revealed a novel de novo point mutation of the OCT-binding site on the maternal allele in one BWS patient. In BWS, all reported mutations and the small deletion of the OCT-binding site, including our case, have occurred within repeat A2. These findings indicate that the OCT-binding site is important for maintaining an unmethylated status of maternal ICR1 in early embryogenesis.

Abstract
CGP 48664A, a new S-adenosylmethionine decarboxylase inhibitor, blocks the production of spermidine and spermine, two polyamines that play critical roles in cellular proliferation. Under in vitro conditions, CGP 48664A produced cytostasis of the human prostate cancer cell lines LNCaP, LNCaP-LN3, PC-3M, and PC-3M-MM2 in a dose-dependent manner. This cytostasis was reversed by the addition of exogenous polyamines to the culture medium. LNCaP-LN3 cells or PC-3M-MM2 cells were implanted into the prostate of nude mice. Daily administration of CGP 48664A significantly inhibited tumor size and serum levels of prostate-specific antigen in mice implanted with LNCaP-LN3 cells. The therapeutic effect was related to the time the treatment was initiated, the volume of disease, and the length of treatment. CGP 48664A was not effective against the fast-growing PC-3M-MM2 tumor. These data suggest that to broaden its effectiveness, CGP 48664A should be combined with other cytoreductive agents.

Abstract
PURPOSE To find the relationship between parents' sleeping and living behaviors and their children's sleeping habits, and to investigate factors specifically related to children staying up late in recent Japan. METHODS During regular health check-ups of children at three local health centers in the city A, we recruited the parents of one-and-half-year-old and three-year-old children to participate in the Child Sleep Cohort Project (ChiSCoP). Parents of 184 children who consented to participation were mailed three questionnaires by placement method. These are "sleeping diary for 10 days," "sleeping and lifetime rhythm survey," and "emotional behavior assessment scale (CBCL : Child Behavior Checklist 2rd/3rd edition)," of which valid data on 178 children were collected over two years and analyzed. ANALYSIS Participants' demographic data, perceived and actual sleeping and living habits, and bedtime patterns were compared among the groups classified by bedtime of children. Bedtimes were classified as early (before 21 : 00), normal (21 : 00 to 21 : 59), and late (after 22 : 00). Using one-way analysis of variance with two (early vs. late) and three bedtime categories, significant differences were found among the three bedtime categories about childcare environmental factors (meal, daytime activity, TV, nap, and bath). So we performed logistic regression analysis with "late bedtime" as the dependent variable and scores of environmental factors (upper or lower than median values) as independent variables in a stepwise manner to eliminate collinear variables and to obtain adjusted odds ratios. RESULTS 1) Among the 178 children, 96 and 82 were recruited during the physical check-up for one-and-half-year-old and three-years-old, respectively. There were 49, 72, and 57 children in the early, normal, and late bedtime groups, respectively, and no significant difference in attribute factors was found. 2) In children of the early bedtime group, proportions of those with "efforts to establish good life rhythm" (P < 0.0001), "efforts to cultivate sleeping habits" (P < 0.0001), and "keeping a regular bedtime" (P < 0.05) were significantly higher, as well as for children who had more than 105 minutes of "daytime nap" compared to children who had less (P < 0.05). 3) Children's bedtimes were significantly correlated with "mother's wake-up time on weekdays" (r = 0.33) and "mother's bedtime on weekdays" (r = 0.33). Children's wake-up times were also correlated with "mother's wake-up time on weekdays and weekends" (r = 0.49) and "mother's bedtime on weekdays" (r = 0.34), which indicates that children's wake-up times had relationship with mother's sleeping and life habits. 4) Later "wake-up time on weekends" (odds ratio = 4.9) and "regular bedtime hour" (odds ratio = 3.53) were found to be the determinant of late bedtimes of children. CONCLUSIONS To encourage earlier bedtimes in children, it is important to take he mother's sleeping and living habits into account and to maintain a regular wake-up and bedtime schedule across weekdays and weekends.

Abstract
OBJECTIVES To determine responses to tocilizumab between patients with rheumatoid arthritis (RA) who switched to anti-TNF agents and those who are biologics-naïve. METHODS This retrospective study investigated 107 patients with RA who were treated with tocilizumab. At baseline, 61 of them had already been treated with anti-TNF agents (switched group; 46 for inefficacy and 15 for adverse events), and 46 were biologics-naïve (naïve group). Treatment responses to tocilizumab at week 12 and 24 were compared between the switched and naïve groups using the disease activity score 28 (DAS28). RESULTS Forty-two (91.3%) and 50 (82.0%) patients in the naïve and switched groups, respectively, completed 24 weeks of tocilizumab treatment. The DAS28-ESR and DAS28-CRP values (means±SD) at weeks 12 and 24 compared to baseline decreased significantly for the naïve and switched groups. The DAS28-ESR and DAS28-CRP values at weeks 12 and 24 were significantly decreased in the naïve group, compared to the switched group. Disease activity was improved in the naïve patients compared to the switched patients. CONCLUSIONS Tocilizumab was safe, tolerable, and clinically effective for patients with inadequate responses to anti-TNF therapy and for those who were biologics-naïve, and it was more effective among the latter.

Abstract
We performed a 20-item questionnaire-based interview of 132 patients with Parkinson's disease (PD): 81 patients with Hoehn & Yahr (H&Y) stage I - III PD, and 51 caregivers of patients with H&Y stage IV - V PD, to evaluate patient and caregiver satisfaction with PD treatment. The survey revealed that PD patients often experience non-motor symptoms, which are not adequately alleviated by antiparkinsonian agents. Furthermore, PD patients want their physicians to listen to them and take their concerns seriously, to explain their disease comprehensively, and to provide the latest information on PD and its treatment. Both patients and caregivers agreed on anxiety toward the future, communication difficulties, and their different movement pace; however, there were differences in their relative perceptions of various aspects of daily care. The evaluation revealed that PD patients have unmet needs in their treatment and standards of care. Areas for future improvement as highlighted in this study include: the development of better treatment for motor symptoms, the development of new treatments for non-motor symptoms and improved two-way communication between patient and physician.

Abstract
BACKGROUND Early reperfusion improves left ventricular (LV) function and survival after acute myocardial infarction (MI). Thrombolytic therapy achieves early patency of the infarct artery in about two-thirds of patients. In nearly half of the remaining patients, in whom early reperfusion was not achieved with thrombolytic therapy, the infarct artery might reopen by the time of predischarge angiography. However, the impact of such late spontaneous reperfusion after failed thrombolytic therapy on LV function and long-term survival remained unclear. HYPOTHESIS This study was undertaken to assess implication of late spontaneous reperfusion after failed thrombolytic therapy on LV function and long-term survival after acute MI. METHODS The study consisted of 198 patients with anterior acute MI who underwent thrombolytic therapy and predischarge angiography: 160 patients with infarct artery patent early and late after therapy (persistent patency), 17 patients with infarct artery occluded early after therapy but patent at predischarge angiography (late spontaneous reperfusion), and 21 patients with infarct artery occluded early and late after therapy (persistent occlusion). RESULTS Persistent patency was associated with enhanced improvement in LV ejection fraction (7.7 +/- 11.8%) compared with late spontaneous reperfusion (0.0 +/- 9.6%, p = 0.03) and persistent occlusion (-1.4 +/- 9.7%, p = 0.003). Persistent patency was associated with better long-term survival than with late spontaneous reperfusion (p < 0.001) and persistent occlusion (p < 0.001). Multivariate analysis comparing persistent patency and late spontaneous reperfusion showed that early reperfusion was an independent predictor of long-term survival. CONCLUSION Late spontaneous reperfusion after failed thrombolytic therapy was associated with poor LV function and long-term survival, emphasizing the importance of early reperfusion.
