Abstract
Abstract
Background
Frailty is a complex syndrome characterized by a decline in functional reserve, and associated with aging and chronic diseases including heart failure (HF). The impact of physical frailty on prognosis and the effect of cardiac rehabilitation in HF patients have been well established. However, the data on the prognostic impact of social frailty (SF) in HF patients is limited.
Aims
We aimed to get new insight into mechanisms of the association of SF with clinical outcomes in older hospitalized HF patients.
Methods
A single-center, retrospective cohort study was conducted using data from 308 HF patients aged ≥65 years (mean age of 78±8 years; 49% females) who were admitted to our institute for the management of HF. SF was assessed using the validated Makizako's five questions. The following responses were considered positive for SF: (1) going out less frequently compared with last year; (2) not visiting friends; (3) not talking with someone every day; (4) not feeling helpful toward friends or family; and (5) living alone. SF was defined as two or more positive responses. The primary outcome was composite events defined by all-cause death and cardiovascular events. The missing data were imputed using multiple imputation by chained -equations algorithm.
Results
Of 308 older HF patients, 189 patients (61%) were SF. Patients with SF were significantly older, had lower body mass index, and a higher percentage of patients with physical frailty and cognitive frailty than those without SF. Seventy-five patients (24%) experienced composite events during a median follow-up period of 1.55-years (interquartile range, 0.88–2.20 years). Kaplan-Meier curves showed a significantly higher composite event rate in patients with SF than those without SF. In multivariate Cox regression analyses, SF was independently associated with a higher composite event rate after adjusting for pre-existing risk factors [adjusted hazard ratio (HR), 1.91; 95% confidence interval (CI), 1.09–3.35; p=0.03] (Figure 1A). In addition, further analyses showed that only the positive response on the question corresponding to the social role – not feeling helpful toward friends or family – among the questionnaire was an independent predictor for the incidence of the composite event (adjusted HR, 2.10; 95% CI, 1.29–3.41; p<0.01, Figure 1B). Inclusion of the response to the question regarding the social role into the baseline prognostic model improved the accuracy of prediction of the composite event (continuous net reclassification improvement, 0.46; 95% CI, 0.21–0.71; p<0.01; integrated discrimination improvement, 0.025; 95% CI 0.004–0.047; p=0.02; Figure 2).
Conclusion
Loss of social role awareness was associated with increased composite event risk and provided additive prognostic information in older HF patients, suggesting the importance of healthcare professionals' decision-making on the prevention and management of SF.

Abstract
Abstract
Background
Sarcopenia, the loss of muscle mass and function, and osteoporosis, a condition of low bone mass and micro-architectural deterioration of bone, frequently coexist and are associated with low functional status in heart failure (HF) patients.
Aims
We aimed to investigate the impact of coexistence of sarcopenia and osteoporosis on functional status in HF patients.
Methods
This cross-sectional study was conducted using data from patients who admitted to our institute for the diagnosis and management of HF from 1 November 2015 to 30 April 2021. All patients received the dual-energy X-ray absorptiometry (DEXA) method before discharge. The diagnosis of sarcopenia was made according to the criteria of Asia Working Group for Sarcopenia 2019 recommendation as follows: reduced skeletal muscle mass [appendicular skeletal muscle mass index (ASMI) by DEXA, <7.00 kg/m2 in males and <5.40 kg/m2 in females] plus lower muscle strength (handgrip strength, <28 kg in males and <18 kg in females) and/or poor physical performance (gait speed, <1.0 m/s; chair stand test time. ≥12 s; short physical performance battery ≤9 points). In addition, bone mineral densities (BMDs) at the lumbar spine, femoral neck, and total femur were measured by DEXA, and osteoporosis was diagnosed when BMDs at any of the three sites were less than 70% of Young Adult Mean (YAM). Functional status was assessed by the Barthel Index (BI) within three days before discharge, and patients with a BI score of <85 points was defined as having functional dependence (FD). The missing data were imputed using multiple imputation by chained -equations algorithm.
Results
Four hundred-thirty eight patients [median age of 74 years (interquartile range, 65–82 years), 37% females] were included in the analyses. Of these, percentage of HF patients with sarcopenia, osteoporosis, and sarcopenia and osteoporosis was 45%, 34%, and 20%, respectively (Figure 1A). The analysis of covariance showed a lower %YAM at any sites in patients with sarcopenia than those without sarcopenia (Figure 1B). When patients were divided into subgroups according to the presence or absence of sarcopenia and osteoporosis, the prevalence of FD was 32%, 34%, and 48% in patients with osteoporosis alone, sarcopenia alone, and sarcopenia and osteoporosis, respectively. Multivariate logistic regression analysis indicated that an increase in adjusted odds ratio (OR) for predicting FD was observed across subgroups in the following order: patients with osteoporosis alone [OR, 1.64; 95% confidence interval (CI), 0.63–4.24; p=0.31], those with sarcopenia alone (OR, 2.44; 95% CI, 1.13–5.25; p=0.02) and those with both conditions (OR, 3.34; 95% CI, 1.52–7.38; p<0.01) (Figure 2).
Conclusion
There was considerable overlap between sarcopenia and osteoporosis in HF patients, which appeared to be a risk factor for FD.

Abstract
BackgroundJAK inhibitor (JAK) and TNF inhibitor (TNF) are the important therapeutic agent for the treatment of rheumatoid arthritis.However there is still few studies of improvement of ultrasonographic findings in RA treated comparison with JAK and TNF.ObjectivesTo evaluate the clinical efficacy of JAK and TNF therapy patients with rheumatoid arthritis (RA) using ultrasonography (US).MethodsParticipants comprised 32 and 39 Japanese RA patients who had recently received JAK (BAR23, PEF9) and TNF. All patients with a diagnosis of RA according to the 2010 ACR/EULAR criteria. Patients underwent clinical and laboratory assessments every 4 weeks from baseline to 24 weeks, and US assessments at baseline, 4, 12 and 24 weeks. Gray scale (GS) and power doppler (PD) signals were scored using a semi-quantitative scale from 0 to 3 at 26 (0-78) synovial sites (22 joints) in the following joints: bilateral first to fifth metacarpopharangeal (MCP) joints (dorsal recess); first interphalangeal (IP) and second to fifth proximal interphalangeal (PIP) (dorsal recess) joints; and the wrists (dorsal radial, median and ulnar). We evaluated the improvement of GS and PD score from baseline to week 24.ResultsIn the patients receiving JAK (n=32) and TNF (n=39), the mean age was 54.7 vs 55.1 years old (p=0.871), disease duration was 7.4 vs 6.1 years (p=0.290), the rate of MTX use was 75% vs 87% (p=0.187), the mean MTX dose was 9.9 vs 10.2 mg/w (p=0.813), the rate of ACPA positive was 94% vs 79% (p=0.086), DAS28-ESR was 4.79 vs 4.65 (p=0.435), CDAI was 22.4 vs 19.1 (p=0.239), GS score was 20.8 vs 18.3 (p=0.995) and PD score was 14.0 vs 11.0 (p=0.940). The degree of improvement respective changes in GS and PD score after 4, 12 and 24 weeks were as follows: GS: -5.1 vs -4.3 (p=0.817) and PD: -5.3 vs -2.7 (p=0.855) after 4 weeks, GS: -9.1 vs -6.6 (p=0.880) and PD: -7.9 vs -4.5 (p=0.476) after 12 weeks, GS: -10.4 vs -9.5 (p=0.463) and PD: -8.1 vs -6.7 (p=0.968) after 24 weeks between JAK and TNF (Figures 1 and 2). Next, The improvement rate of respective changes in GS and PD score after 4, 12 and 24 weeks were as follows: GS: -13.7% vs -18.3% (p=0.489) and PD: -20.4% vs -16.5% (p=0.777) after 4 weeks, GS: -29.7% vs -26.0% (p=0.922) and PD: -30.9% vs -30.8% (p=0.890) after 12 weeks, GS: -38.1% vs -36.4% (p=0.567) and PD: -33.4% vs -50.1% (p=0.977) after 24 weeks between JAK and TNF.ConclusionThe present study provides evidence supporting the JAK and TNF therapy improved similarly the inflammatory synovitis of US findings.Disclosure of InterestsNone declared

Introduction
Sarcopenia is associated with poor functional status and clinical outcomes in heart failure (HF) patients. Although recent observational studies showed the relationship between lower serum vitamin D levels and the development of poor physical function in community-dwelling older adults, involvement of vitamin D status in the development of sarcopenia in HF patients remain unclear. This study aimed to investigate the impact of serum vitamin D concentrations on sarcopenia in patients with HF.
Methods
We retrospectively enrolled 269 consecutive patients [median age of 73 years (interquartile range 63-82 years); 35% female] admitted to our institute for diagnosis and management of HF, and received the dual-energy X-ray absorptiometry (DEXA) method during the period from 1 September 2018 to 30 September 2021. The 25-hydroxyvitamin D [25(OH)D] was detected by a chemiluminescence immunoassay (CLIA) technology. The diagnosis of sarcopenia was made according to the criteria of Asia Working Group for Sarcopenia incorporating reduced skeletal muscle mass (appendicular skeletal muscle index [ASMI], <7.00 kg/m2 in males and <5.40 kg/m2 in females), and lower muscle strength (handgrip strength, <28 kg in males and <18 kg in females) and/or poor physical performance (gait speed, <1.0 m/s; chair stand test time, ≥12 s; short physical performance battery, ≤9 points).
Results
Of 269 patients, 116 (43%) patients had sarcopenia. An adjusted logistic regression model with a restricted cubic spline function showed that the odds ratio (OR) for sarcopenia increased as the serum 25(OH)D levels decreased. When the value that corresponded to an upper limit of 95% confidence interval (CI) for an OR of 1.0 was defined as the cut-off value of 25(OH)D levels for predicting sarcopenia, it was 18 ng/mL (Figure 1A). A multivariate logistic regression model was fit to calculate the propensity score (PS) for the 25(OH)D levels being <18 ng/mL based on covariates such as age, sex, and N-terminal pro B-type natriuretic peptide. (C-statistics 0.761). The inverse probability of treatment weighting (IPTW) was computed using PS to minimize differences in potential confounding factors between patients with a low serum 25(OH)D levels (<18 ng/mL) and those with a high serum 25(OH)D levels (≥18 ng/mL, Figure 1B). Results of the multivariate logistic regression analysis in the IPTW-weighted patients showed that a low serum 25(OH)D was independently associated with presence of sarcopenia (adjusted OR 2.03, 95% CI 1.31-3.16, p<0.01). In addition, patients with a low serum 25(OH)D had a significantly lower muscle strength and poor physical performance, but not ASMI, than those with a high serum 25(OH)D (Figure 2).
Conclusion
Decreased serum 25(OH)D levels are associated with decline in muscle strength and physical performance in HF patients. Serum 25(OH)D levels of <18 ng/mL may be a novel risk factor of sarcopenia in HF patients.

Background
Skeletal muscle mass in heart failure (HF) patients is closely related to exercise tolerance and prognosis. Although the dual-energy X-ray absorptiometry (DEXA) method is a standard method for measuring skeletal muscle mass, it is not suitable in a daily clinical setting since it is a costly and hospital-based modality. We recently reported that an equation for appendicular skeletal muscle mass index (ASMI) estimation using anthropometric parameters predicted DEXA-measured ASMI in HF patients with reasonable accuracy. Here, we examined the prognostic impacts of ASMI predicted by the equation (predicted ASMI) in HF patients.
Methods
Data for 539 patients with HF ( 73 ± 14 years old, 43% female) who received the DEXA method and measurements of calf circumference (CC) and mid-arm circumference (MAC) between August 1, 2015, to August 31, 2020, were used for analyses. DEXA measured-appendicular skeletal muscle (ASM) was calculated as the sum of bone-free lean masses in the arms and legs, and ASMI was defined as ASM/height². Predicted ASMI was calculated as we previously reported: predicted ASMI (kg/m²) = [0.214 × weight (kg) + 0.217 × CC (cm) - 0.189 × MAC (cm) + 1.098 (male = 1, female = -1) + 0.576]/height² (m²). Low ASMI was defined as <7.0 kg/m² in males and <5.4 kg/m² in females, respectively. The primary endpoint was all-cause death. Multiple imputation using chained equations was used for the substitution of missing values.
Results
The median follow-up period was 1.75 years (interquartile range, 0.96 to 2.37 years), and 73 patients (15%) has died. Kaplan-Meier survival curves showed that patients with low DEXA measured-ASMI and patients with low predicted ASMI had significantly lower survival rates than those with high ASMI (Figure 1). In a multivariate Cox proportional hazard analyses adjusted for age, sex, logarithmic B-type natriuretic peptide, cystatin C based-estimated glomerular filtration rate, and gait speed, DEXA-measured ASMI [hazard ratio (HR), 0.982; 95% confidence interval (CI), 0.967 to 0.988; p<0.001] and predicted ASMI (HR, 0.979; 95% CI, 0.962 to 0.996; p=0.018) were independent predictors of all-cause mortality, respectively. Inclusion of predicted ASMI into the adjustment model improved the accuracy of prediction of the mortality after discharge [continuous net reclassification improvement, 0.338, p<0.01; integrated discrimination improvement, 0.020, p < 0.05] (Figure 2).
Conclusions
ASMI estimated by an equation using CC and MAC predicted the prognosis of HF patients at a similar level of accuracy to DEXA-measured ASMI, and it can be applied to the assessment of skeletal muscle mass in a daily clinical setting and in large population-based studies.

Abstract
Abstract
Background
Accurate prediction of mortality in heart failure (HF) patients is crucial for decision-making regarding HF therapies, but a strategy for the prediction of mortality in elderly HF patients has not been established. In addition, although favorable effects of comprehensive cardiac rehabilitation (CR) on clinical outcomes and functional status in HF patients have been demonstrated, a goal of comprehensive CR during hospitalization for reducing mortality remains unclear.
Aims
We examined whether assessment of basic activities of daily living (ADL) by the Barthel Index (BI), the most widely used tool for assessment of basic ADL, is useful for predicting all-cause mortality in elderly HF patients who received comprehensive CR.
Methods
This study was a single-center, retrospective and observational study. We retrospectively examined 413 HF patients aged ≥65 years (mean age, 78±7 years; 50% female) who were admitted to our institute for management of HF and received comprehensive CR during hospitalization. Functional status for performing basic ADL ability was assessed by the BI within 3 days before discharge. The clinical endpoint was all-cause death during the follow-up period.
Results
Of 413 HF patients, 116 patients (28%) died during a follow-up period of median 1.90-years (interquartile range, 1.20–3.23 years). Results of an adjusted dose-dependent association analysis showed that the hazard ratio (HR) of mortality increases in an almost linear fashion as the BI score decreases and that the BI score corresponding the hazard ratio of 1.0 is 85 (Figure A). To minimize the differences in potential confounding factors between patient with low BI (<85) and patients with high BI (≥85), inverse probability treatment weighting (IPTW) was calculated using propensity score. Kaplan-Meier survival curves, in which selection bias was minimized by use of IPTW for confounders, showed that patients with low BI (<85) had a higher mortality rate than did patients with high BI (≥85) (Figure B). In multivariate Cox regression analyses, low BI was independently associated with higher mortality after adjustment for predictors including brain natriuretic peptide and prior HF hospitalization (IPTW-adjusted HR, 1.75 [95% confidence interval, 1.03–2.98], p<0.001). Inclusion of the BI into the adjustment model improved the accuracy of prediction of mortality (continuous net reclassification improvement, 0.292, p=0.008; integrated discrimination improvement, 0.017, p=0.022).
Conclusion
A BI score of <85 at the time of discharge is associated with increased mortality independently of known prognostic markers, and achievement of functional status of a BI score ≥85 by comprehensive CR during hospitalization may contribute to a favorable outcome in elderly HF patients.

Abstract
Study question
This article aims to characterize from a socio-demographic point of view, women of reproductive age who wish to have children, declared themselves infertile, and their search for treatments and outcomes.
Summary answer
It is essential to develop specific population surveys on infertility in Brazil to identify its magnitude and main economic and social components.
What is known already
Commonly neglected in developing countries where public policy is incipient, infertility brings social, economic and psychological consequences to couples. It is considered as a serious public health problem whose impact varies among different populations and acquires relevance for specific communities. In Brazil, there are no clinical or demographic data that point us to the magnitude of the problem, its social characteristics and impact. Taking into account the postponement of motherhood for after 30 years, there will probably be an increase in the number of women and couples who may resort to infertility treatments to fulfil the desire for procreation.
Study design, size, duration
The National Survey of Demography and Health of Women and Children (PNDS) is a cross-sectional study and a household complex probabilistic sampling. The sampling units were selected according to a stratified model of simple random conglomerates in two stages: lottery draw and household draw. The last survey was conducted between June 2006 and May 2007 in 14,617 households. In the selected households, interviews were conducted with 15,575 women of reproductive age.
Participants/materials, setting, methods
The participants consisted of 15.575 women between 15 and 49 years, representative of the five Brazilian macro-regions. The information was obtained through questionnaires, applied in person, raising information on fertility, fecundity, contraception, use of health services and socioeconomic profile. The interviewer’s team was formed by approximately 100 people and 27 supervisors, all-female, divided into nine regional teams. The system used for data entry was the Census and Survey Processing System - CSPro.
Main results and the role of chance
The survey results indicate that of women who wish to have children, 9.2% declared themselves infertile; 50,8% of them sought health services for treatment; non-black women had higher percentages of demand compared to black women (62.4% versus 41.3%). Also, there were higher percentages of seeking help from women belonging to classes A (61.2%), B (83.3%) and C (60.9%) compared to those belonging to classes D (30.4%) and E (7.8%) On the other side, almost half of women did not seek help to get pregnant (49,1%); this percentage is higher among black women (58%). Moreover, women in classes D and E had the highest percentages of non-demand, 69.6% and 92.2%, respectively. The reasons cited for those who do not seek help, are “I think there is no solution” (54,7%); “I don’t think I can get help” (17.3%), “financial reasons” (26.8%) or “I don’t know where to get it” (1,2%). Among those who sought help, 48,5% are under treatment, 24,4% said there is no solution; 15,8% are waiting for service and 11,3% have no money for treatment. Significance limit was established for values of p < 0.05. The analysis was performed in the programs Stata v.9 and/or SPSS v.14.
Limitations, reasons for caution
The limitations of the study are recognized. Firstly, opinions are restricted to the moment of the interview and, thus, the desire for children may change over time. Secondly, the statement of infertility is based on self-declaration, not on clinical diagnosis.
Wider implications of the findings: This is the first study based on PNDS 2006 data on infertility and demand for treatments in Brazil. It can contribute to providing insights, raising new questions and discovering relevant categories and dimensions of analysis to be taken into account in future studies and surveys.

Abstract
Background:Symptoms in patients with rheumatoid arthritis (RA) are potentially influenced by exercise load and meteorological change, and often vary from day to day, especially in unstable condition of RA. Patients with RA not infrequently experience worsening of joint symptoms when the load on the joint, such as walking and doing housework, exceeds a moderate range. However, the worsening of joint symptoms is often not observed in the midst of the loading of the joint, but often becomes apparent after a few hours or days.Objectives:To elucidate the relationship between smartphone- and smartwatch-acquired daily objective data (barometric pressures, steps, and activity) and daily subjective patient reported outcomes of RA.Methods:A smartphone (iPhone 8) and a wristband-type smartwatch (Fitbit Versa 2) were lent to each patient for free. A mobile app was developed and installed into the smartphones to collect patients’ daily subjective RA symptoms including Pt-P-VAS (patient-pain-visual analogue scale), Pt-G-VAS (pt-general-VAS), PtTJCount(68)(patient self-determined tender joint count among 68 joints), PtTJCount(28), PtSJCount(66)(patient self-determined swollen joint count among 66 joints), PtSJCount(28). Also, the smartwatch data and physicians’ assessment were collected from the same subject. Physicians’ and patients’ assessment of TJC, SJC, and G-VAS was independently performed without seeing each other’s assessment.We conducted a simple linear regression analysis with outcome variables of Pt-P-VAS, Pt-G-VAS, PtTJCount(68), PtTJCount(28), PtSJCount(66), and PtSJCount(28). The independent variables included smartphone-acquired daily steps and barometric pressure of the reported day and the previous day, and smartwatch-acquired minutes of “lightly active (1-3 METs equivalent)”, “fairly active(3-6 METs equivalent)”, and “very active(>6 METs equivalent)” of the reported day and previous day. We defined low barometric pressure as below 1000 hPa. The level of activity was measured by the smartwatch. Patients were blinded to daily barometric pressure data and their daily active time when the patients answered daily symptom questions on the smartphones.Results:A total of five patients were enrolled. At baseline, mean (± standard deviation (SD)) age was 50.8±14.8 years; all patients were females; mean disease duration was 6.6±4.9 years; mean SDAI was 18.6±25.5; mean DAS28-CRP was 3.23±1.85; mean morning stiffness was 134±116 min; mean HAQ-DI was 0.7±0.9. Mean observation period was 77.8 days. Because of the missing data, the sample size (N) for the regression analysis varies with the outcomes: Pt-P-VAS and Pt-G-VAS are 250 while PtTJCount and PtSJCount are 260.The table 1 showed that the patients’ assessment of TJC, SCJ, and G-VAS was correlated well with the physicians’ assessment.Table 1.Evaluation itemCorrelation between physicians and patients (ρ)Tender Joint Count (68)0.909Tender Joint Count(28)0.913Swollen Joint Count(66)0.896Swollen Joint Count(28)0.890General VAS0.688The figure 1 showed the change associated with one SD increment in each independent variable with 90% confidence intervals. Low barometric pressure was associated with bad health conditions (high Pt-G-VAS, Pt-P-VAS, and SJCount). Moreover, longer very active time in the previous day (“veryactive_1” in the Figure 1) was associated with bad health condition (high SJCount). Many steps were associated with good health conditions (low Pt-G-VAS, Pt-P-VAS, and SJCount).Figure 1.Conclusion:High barometric pressure was associated with good health conditions, and longer very active time in the previous day was associated with bad health condition. Barometric pressure data and physical activity data acquired by mobile digital devices may predict the change in RA symptoms. Further investigation in larger patient numbers is warranted.Acknowledgements:The authors would like to thank Harumi Kondo for her assistance.Disclosure of Interests:Keisuke Izumi Speakers bureau: Abbvie, Asahi Kasei Pharma, Bristol Myers Squibb, Chugai Pharmaceutical, Eli-Lily, Mochida Pharmaceutical, Ono Pharmaceutical, Grant/research support from: Abbvie, Asahi Kasei Pharma, Daisuke Moriwaki Employee of: CyberAgent, Inc., Takamichi Toda Employee of: AI Shift, Inc., Misako Higashida-Konishi: None declared, Manami Koyama: None declared, Hisaji Oshima: None declared, yutaka okano Speakers bureau: Asahi Kasei Pharma, Yuko Kaneko Speakers bureau: AbbVie, Astellas, Ayumi, Bristol–Myers Squibb, Chugai, Eisai, Eli Lilly, Hisamitsu, Jansen, Kissei, Kirin, Novartis, Pfizer, Sanofi, Takeda, Taisho, Tanabe-Mitsubishi, and UCB, Shigeru Ko: None declared, Tsutomu Takeuchi Speakers bureau: Abbott Japan Co, Ltd, Bristol–Myers KK, Chugai Pharmaceutical Co, Ltd, Eisai Co, Ltd, Janssen Pharmaceutical KK, Mitsubishi Tanabe Pharma Co, Pfizer Japan Inc, Takeda Pharmaceutical Co, Ltd, Astellas Pharma and Daiichi Sankyo Co, Ltd., Consultant of: Astra Zeneca KK, Eli Lilly Japan KK, Novartis Pharma KK, Mitsubishi Tanabe Pharma Co, Asahi Kasei Medical KK, Abbvie GK and Daiichi Sankyo Co, Ltd., Grant/research support from: Abbott Japan Co, Ltd, Astellas Pharma, Bristol-Myers KK, Chugai Pharmaceutical Co, Ltd, Daiichi Sankyo Co, Ltd, Eisai Co, Ltd, Janssen Pharmaceutical KK, Mitsubishi Tanabe Pharma Co, Pfizer Japan Inc, Sanofi–Aventis KK, Santen Pharmaceutical Co, Ltd, Takeda Pharmaceutical Co, Ltd, Teijin Pharma Ltd, Abbvie GK, Asahikasei Pharma Corp and Taisho Toyama Pharmaceutical Co, Ltd.

Abstract
Background:Baricitinib (BAR) and TNF antagonist are the important therapeutic agent for the treatment of rheumatoid arthritis.However there is still few studies of improvement of ultrasonographic findings in RA treated comparison with BAR and TNF.Objectives:To evaluate the clinical efficacy of BAR and TNF therapy patients with rheumatoid arthritis (RA) using ultrasonography (US).Methods:Participants comprised 16 and 45 Japanese RA patients who had recently received BAR and TNF. All patients with a diagnosis of RA according to the 2010 ACR/EULAR criteria. Patients underwent clinical and laboratory assessments every 4 weeks from baseline to 24 weeks, and US assessments at baseline, 4, 12 and 24 weeks. Gray scale (GS) and power doppler (PD) signals were scored using a semi-quantitative scale from 0 to 3 at 26 (0-78) synovial sites (22 joints) in the following joints: bilateral first to fifth metacarpopharangeal (MCP) joints (dorsal recess); first interphalangeal (IP) and second to fifth proximal interphalangeal (PIP) (dorsal recess) joints; and the wrists (dorsal radial, median and ulnar). We evaluated the improvement of GS and PD score from baseline to week 24.Results:In the patients receiving BAR (n=16) and TNF (n=45), the mean age was 55.9 vs 54.6 years old (p=0.682), disease duration was 10.2 vs 6.1 years (p=0.094), the rate of MTX use was 75% vs 89% (p=346), the mean MTX dose was 9.3 vs 10.2 mg/w (p=0.443), the rate of ACPA positive was 94% vs 82% (p=0.476), DAS28-ESR was 4.25 vs 4.61 (p=0.289), CDAI was 15.8 vs 18.5 (p=0.210), GS score was 21.6 vs 16.3 (p=0.436) and PD score was 15.0 vs 9.5 (p=0.260). The degree of improvement respective changes in GS and PD score after 4, 12 and 24 weeks were as follows: GS: -7.2 vs -3.7 (p=0.268) and PD: -7.6 vs -2.3 (p=0.158) after 4 weeks, GS: -10.9 vs -5.0 (p=0.161) and PD: -9.2 vs -3.8 (p=0.049) after 12 weeks, GS: -12.9 vs -6.1 (p=0.485) and PD: -11.3 vs -5.7 (p=0.062) after 24 weeks between BAR and TNF (Fig.1, 2). Next, The improvement rate of respective changes in GS and PD score after 4, 12 and 24 weeks were as follows: GS: -23.8% vs -11.6% (p=0.580) and PD: -30.3% vs -16.5% (p=0.343) after 4 weeks, GS: -39.6% vs -15.6% (p=0.129) and PD: -47.1% vs -30.8% (p=0.210) after 12 weeks, GS: -52.2% vs -22.2% (p=0.248) and PD: -77.1% vs -50.1% (p=0.048) after 24 weeks between BAR and TNF.Conclusion:The present study provides evidence supporting both the BAR and TNF therapy showed improvement effect over time, but in a comparison between BAR and TNF, the PD score of BAR showed a siginificant improvement effect compared to TNF at 12 and 24 weeks. It was suggeted that BAR may improve inflammatory synovitis earlier compared to TNF.Disclosure of Interests:None declared

Abstract
Abstract
Background
Despite accumulating evidence of a close association between orthopedic fractures and chronic heart failure (CHF), the clinical risk factors of osteoporosis, defined as reduction in bone mineral densities (BMDs), in CHF patients have not been systematically analyzed. In addition, the impact of osteoporosis on prognosis of CHF remains unclear.
Aims
We aimed to clarify the prevalence, clinical risk factors, and prognostic impact of osteoporosis in CHF patients.
Methods
We retrospectively examined 303 CHF patients (75 years, [interquartile range (IQR), 66–82 years]; 41% female). BMDs at the lumber spine, femoral neck, and total femur were measured by dual-energy X-ray absorptiometry (DEXA), and osteoporosis was diagnosed when BMD at any of the three sites was less than 70% of Young Adult Mean.
Results
The prevalence of osteoporosis in the CHF patients was 40%. Patients with osteoporosis were older (79 [IQR, 74–86] vs. 72 [IQR, 62–80] years), included a large percentage of females, had slower gait speed and had lower body mass index (BMI). Loop diuretics and warfarin were used more frequently and direct oral anticoagulants (DOACs) were used less frequently in patients with osteoporosis than in patients without osteoporosis. Multivariate logistic regression analysis indicated that sex (odds ratio [OR] 5.07, 95% Confidence Interval [CI] 2.68–9.61, p<0.01), BMI (OR, 0.83; 95% CI, 0.75–0.91; p<0.01), gait speed (OR, 0.80; 95% CI, 0.70–0.92; p<0.01), loop diuretics use (OR, 2.52; 95% CI, 1.20–5.27; p=0.01) and no DOACs use (OR, 0.43; 95% CI, 0.19–0.96; p=0.04) were independently associated with osteoporosis. During the mean follow-up period of 290±254 days, 92 patients (30.4%) had adverse events. When patients with osteoporosis were divided into subgroups according to the number of sites with BMD of an osteoporosis level, Kaplan-Meier survival curves showed that the rate of adverse events (death and cardiovascular events) was higher in patients with osteoporotic BMD at two or more sites than in patients without osteoporosis (51% vs. 23%, p=0.03) (Figure). In multivariate Cox regression analyses, osteoporotic BMD at two or more sites was an independent predictor of adverse events after adjustment for age, sex, and NT-proBNP level (Hazard ratio, 1.74; 95% CI, 1.01–2.99; p=0.04).
Conclusion
The risk of osteoporosis may be increased in users of loop diuretics and may be decreased in users of DOACs in CHF patients. Extent of osteoporosis is a novel predictor of adverse events in CHF patients.

Abstract
Abstract
Background
Obesity, defined as higher body mass index (BMI), is associated with better prognosis in patients with chronic heart failure (CHF), though the presence of obesity is a risk factor of development of CHF (Obesity paradox). On the other hand, muscle wasting, i.e. reduction in skeletal muscle mass, is frequently observed in CHF, leading to lower exercise capacity and poor cardiovascular outcome.
Purpose
The aim of this study was to examine whether analysis of body composition improves prediction of short-term readmission rates in patients with CHF.
Methods
We retrospectively analyzed data for 167 consecutive HF patients who were admitted to our institute for management of HF and received a Dual-energy X-ray absorptiometry (DEXA) scan. Muscle wasting was defined as DEXA-measured appendicular skeletal muscle mass index <7.0 kg/m2 in male and <5.4 kg/m2 in female according to the Asian Working Group for Sarcopenia criteria. Obesity was defined according to the criteria by the use of DEXA-measured percent body fat mass: >25% in male, >30% in female. The primary endpoint was readmission due to cardiac events including worsening heart failure, arrhythmia, and cardiopulmonary arrest during a 180-days follow-up period after discharge.
Results
The mean age of the patients was 74±13 years and 46% of them were male. The mean BMI was 21.8±3.8 kg/m2. Forty-seven percent of the patients were classified as NYHA functional class III. The most frequent etiology of HF was cardiomyopathy (30%), followed by ischemic heart disease (27%) and valvular heart disease (27%). The prevalence of muscle wasting and that of obesity were 69% and 59%, respectively. Patients with muscle wasting had lower BMI level, higher prevalence of NYHA functional class III and diabetes mellitus compared with those without muscle wasting. On the other hand, patients with obesity had higher prevalence of hypertension and dyslipidemia, higher level of BMI, fasting plasma insulin and triglyceride, and lower level of HDL-cholesterol compared with those without obesity. During the follow-up period, 34 patients (19%) were re-hospitalized due to cardiac events. Kaplan-Meier survival curves showed that patients with obesity had a significantly lower readmission rate during a 180-days follow-up period than did the patients without obesity (14.3% vs. 29.0%, Log-Rank test, p<0.01). There was no difference in readmission rates between patients with and without muscle wasting (20.0% vs. 21.2%, p=0.88). In multivariate Cox regression analyses adjusted for age, sex, diabetes, and renal function, obesity was independently associated with lower readmission rates (hazard ratio 0.45, 95% confidence interval 0.22–0.93). However, the association between obesity and readmission rate was lost after the adjustment for NT-proBNP levels.
Conclusion
Body composition analysis by DEXA enables to find CHF patients with increased fat mass who have lower risk of short-term readmission.

Abstract
Abstract
Background
Malnutrition is frequently present and closely associated with poor clinical outcomes in elderly heart failure (HF) patients. Our previous study showed that low energy intake (EI) is associated with worse functional status in elderly HF inpatients after cardiac rehabilitation, but significance of EI in prediction of hospital readmission has not been elucidated fully.
Purpose
We examined whether low EI is a predictor of readmission for cardiac events in elderly HF patients.
Methods
We retrospectively retrieved data for 298 HF patients aged ≥65 years (median age of 77 years, interquartile range [IQR]: 71 - 82, female: 53%) who admitted to our institute for diagnosis and treatment of HF. Medical records were reviewed with regard to demography, medical history, comorbidities, medications, laboratory data, echocardiograms, functional status, nutritional status and total energy intake. Nutritional status was assessed using the Mini Nutritional Assessment Short Form (MNA-SF) and total EI per day were calculated at discharge by a registered dietitian and a trained physical therapist. The primary endpoint was readmission due to cardiovascular events including worsening HF, arrhythmia, angina pectoris and myocardial infarction during a 1-year follow-up period.
Results
The median period of follow-up was 235 days (IQR: 78–365 days). The 1-year readmission rate for cardiovascular events was 54.4%. The cutoff values of MNA-SF score and EI, calculated by ROC curve analysis to predict the primary endpoint, were 7 points (area under the curve [AUC]: 0.59, sensitivity: 0.65, specificity: 0.50) and 31.8 kcal/kg/day (AUC: 0.59, sensitivity: 0.83, specificity: 0.35), respectively. Patients with low MNF-SF score (≤7) or low EI (≤31.8 kcal/kg/day) had significantly higher readmission rate during a 1-year follow-up period than did the patients with high MNF-SF score or EI (MNA-SF: 60.7% vs. 45.6%, p<0.01, EI: 60.4% vs. 36.8%, p<0.01), respectively. When patients were classified into four groups using cutoff values of MNA-SF score and EI, 1-year readmission rate was significantly higher in patients with low EI than in those with high EI regardless of MNF-SF scores. In multivariate Cox proportional hazard analyses adjusted for known prognostic factors in addition to age and gender, hazard ratios (HR) were significantly higher in patients with high MNA-SF score and low EI (adjusted HR: 2.81, 95% confidential interval [CI]: 1.15 - 9.32, p=0.02) and low MNA-SF score (≤7) and low EI (adjusted HR: 4.16, 95% CI: 1.72 - 13.72, p<0.01) than those with high MNA-SF score and high EI.
Kaplan-Meier curves of readmission rates
Conclusions
Low energy intake is a nutritional status-independent predictor of 1-year readmission rate in elderly HF patients.

Abstract
Abstract
Background
Necroptosis, a form of programmed necrosis, has been suggested to be involved in the pathogenesis of various pathological conditions including heart failure. Protein expression of caspase-8, an endogenous inhibitor of necroptosis, is reported to be downregulated in human failing hearts, but its clinical significance remains unclear.
Methods
Endomyocardial biopsy specimens were obtained from patients with nonischemic dilated cardiomyopathy (n=57, 56.2±14.5 years old, 70% male). The area stained with antibodies against caspase-8 and phospho-MLKL-Ser358 was calculated using an image analyzer, and fibrotic and cardiomyocyte areas were determined by Masson's Trichrome staining. Using a level of median caspase-8 expression (6.04% of the area of the myocardium with caspase-8 signal), patients were classified into a high caspase-8 expression group (H-cas8) and a low caspase-8 expression group (L-cas8).
Results
Caspase-8 signals were detected in cytoplasm and intercalated disks of cardiomyocytes. Patients in the L-cas8 group was younger (51.3±13.1 vs. 61.2±14.3 years old) and had larger left ventricular end-diastolic volume (LVEDV: 174±49 vs. 131±41 ml), larger left ventricular end-systolic volume (LVESV: 123±51 vs. 87±39 ml), and higher ratio of mitral peak velocity of early filling to late diastolic filling (E/A: 1.94±1.48 vs. 1.12±0.66) compared with the H-cas8 group. Caspase-8 expression level was positively correlated with age (r=0.34, p=0.01) and negatively correlated with LVEDV (r=−0.47, p<0.01), LVESV (r=−0.40, p<0.01), and E/A (r=−0.39, p<0.01) in simple linear regression analysis. The extent of myocardial fibrosis was not correlated with caspase-8 expression level. Multiple regression analysis indicated that LVEDV, LVESV, and E/A were independent explanatory factors of caspase-8 expression level after adjusting age and sex. Phospho-MLKL signals, an index of activation of necroptotic pathway, were frequently observed in cytoplasm, intercalated disks, and nuclei in the L-cas8 group but not in the H-cas8 group.
Conclusion
Lower caspase-8 expression in cardiomyocytes was associated with increased phosphorylation of MLKL and larger left ventricular volume, suggesting that downregulated caspase-8 may contribute to progression of myocardial remodeling via activation of MLKL in human dilated cardiomyopathy.

Abstract
Purpose: We compared laparoscopic redo fundoplications performed for failed laparoscopic Toupet fundoplication (LTF) and failed laparoscopic Nissen fundoplications (LNFs). Methods: Redo LTF (R-LTF; n = 4) and redo LNF (R-LNF; n = 6) performed between 2007 and 2014 were assessed retrospectively for severity of intraperitoneal adhesions on a scale of 0–3, identification/preservation of the anterior/posterior/hepatic branches of the vagus nerve (VN), complications, and outcome. Results: Redos were performed after a mean of 34 months in R-LTF and 32 months in R-LNF (P = ns) indicated for sliding hernia (n = 3; 2 with partial wrap dehiscence) and partial wrap dehiscence (n = 1) in R-LTF and sliding hernia (n = 6; 4 with partial wrap dehiscence) in R-LNF. The mean adhesion severity score was 1.5 in R-LTF and 2.5 in R-LNF (P < 0.05). The mean number of VN branches identified/preserved was 2.0 in R-LTF and 0.8 in R-LNF (P < 0.05). Mean operative times and mean blood loss were similar. Intraoperative complications were accidental local trauma (n = 1 in R-LTF and n = 3 in R-LNF, one requiring conversion to open repair) (P = ns). Gastric outlet obstruction developed in two R-LNF cases; both were managed conservatively. There have been no further recurrences to date. Conclusion: Although our series is small, adhesions were less, and identification/preservation of VN was easier during R-LTF.

Abstract
INTRODUCTION We compared laparoscopic Toupet fundoplication (LTF) and laparoscopic Nissen fundoplication (LNF) in neurologically normal children. METHODS Forty neurologically normal children who were followed up for more than 3 years after LTF (n = 22) or LNF (n = 18) were reviewed retrospectively. LTF and LNF were performed between 2006 and 2012. RESULTS There were no significant differences in gender (LTF, 15 male and 7 female patients; LNF:, 12 male and 6 female patients), mean age at surgery (LTF vs LNF: 2.5 vs 2.3 years), mean weight at surgery (LTF vs LNF: 9.6 vs 8.9 kg), preoperative symptoms, preoperative pH monitoring (pH <4) (LTF vs LNF: 26.7% vs 21.8%), mean operative time (LTF vs LNF: 117 vs 126 min), postoperative recommencement of enteral feeding (LTF vs LNF: 3.7 vs 3.8 days), or duration of hospitalization (LTF vs LNF: 5.5 vs 6.3 days). Intraoperative complications were esophageal trauma (LTF; n = 1; 4.5%) and liver trauma (LNF; n = 1; 5.6%) (P = 0.70). Post-LTF complications were wrap stenosis (n = 1; 4.5%), and post-LNF complications were wrap stenosis (n = 1; 5.5%) and gastric outlet obstruction (n = 1; 5.5%) (P = 0.43); all were managed conservatively. No case required conversion to open repair. There was no recurrence after LTF, but there were three cases (16.7%) after LNF (P = 0.08). Reoperation was performed at 4, 11, and 13 months, respectively. CONCLUSION Despite LTF and LNF appearing to be equally effective, three LNF cases required reoperation.

Abstract
INTRODUCTION The aim of this study was to compare laparoscopic hepaticojejunostomy (LHJ) and open hepaticojejunostomy (OHJ) for choledochal cyst associated with hilar hepatic duct stenosis (HHDS). METHODS Data collection was prospective for LHJ cases from 2009 and retrospective for OHJ cases from 2003 to 2008. Data were compared with respect to HHDS. HHDS was incised longitudinally as required during hilar hepatic ductoplasty. RESULTS Fifty-eight subjects were studied (LHJ: n = 27, 4 boys, 23 girls; OHJ: n = 31; 6 boys, 25 girls). HHDS was present in 10 LHJ cases and 10 OHJ cases. Todani classification of choledochal cyst in LHJ patients was type 1A (n = 16) and type 4A (n = 11), and in OHJ patients, it was type 1A (n = 19) and type 4A (n = 12). There were significant differences between LHJ and OHJ with regard to mean operative time (386 vs 341 min), mean blood loss (5.9 vs 18.4 mL), recommencement of enteral feeding (3.9 vs 6.4 days), and hospital stay (11.7 vs 15.5 days) (all P < 0.05). Hepatic ductoplasty was performed in 23 LHJ patients and in 21 OHJ patients. There were no intraoperative complications and no conversions to OHJ. There were no significant differences between LHJ and OHJ, regardless of the presence of HHDS, for postoperative complications, which included minor bile leakage, anastomotic stricture, and intestinal obstruction. CONCLUSION LHJ is as effective as OHJ for the treatment of choledochal cysts irrespective of the presence of HHDS and the need for hepatic ductoplasty.

Abstract
Purpose Patients with asplenia syndrome (AS) are likely to have upper gastrointestinal tract malformations such as hiatal hernia. This report discusses the treatment of such conditions. Methods Seventy-five patients with AS underwent initial palliation in our institution between 1997 and 2013. Of these, 10 patients had hiatal hernia. Of the patients with hiatal hernia, 6 had brachyesophagus and 7 had microgastria. Results Of the 10 patients with hiatal hernia, 9 underwent surgery in infancy (7 before Glenn operation, 2 after Glenn operation). Two underwent typical Toupet fundoplication, and the other 7 underwent atypical repair including reduction of the stomach. Two patients with atypical repair showed recurrence of hernia and required reoperation. Three patients required reoperation due to duodenal obstruction. Duodenal obstruction occurred due to preduodenal portal vein or abnormal vessels compressing the duodenum. Obstructive symptoms were not seen in any cases preoperatively. Conclusions In patients with hiatal hernia, typical fundoplication is often difficult because most have concomitant brachyesophagus, microgastria, and hypoplasia of the esophageal hiatus. However, we should at least reduce the stomach to the abdominal cavity as early as possible to increase thoracic cavity volume and allow good feeding. Increasing the volume of the thoracic cavity thus makes Glenn and Fontan circulations more stable. Duodenal obstruction secondary to vascular anomalies is also common, so the anatomy in the area near the duodenum should be evaluated pre- and intraoperatively.

Abstract
AIMS To compare insulin glargine 300 U/mL (Gla-300) with glargine 100 U/mL (Gla-100) in Japanese adults with uncontrolled type 2 diabetes on basal insulin and oral anti-hyperglycaemic drugs over 12 months. METHODS EDITION JP 2 was a randomised, open-label, phase 3 study. Following a 6-month treatment period, participants continued receiving previously assigned once daily Gla-300 or Gla-100, plus oral anti-hyperglycaemic drugs, in a 6-month extension period. Glycaemic control, hypoglycaemia and adverse events were assessed. RESULTS The 12-month completion rate was 88% for Gla-300 and 96% for Gla-100, with comparable reasons for discontinuation. Mean HbA1c decrease from baseline to month 12 was 0.3% in both groups. Annualised rates of confirmed (≤3.9mmol/L [≤70mg/dL]) or severe hypoglycaemia were lower with Gla-300 than Gla-100 (nocturnal [00:00-05:59h]: rate ratio 0.41; 95% confidence interval: 0.18 to 0.92; anytime [24h]: rate ratio 0.64; 95% confidence interval: 0.44 to 0.94). Cumulative number of hypoglycaemic events was lower with Gla-300 than Gla-100. Adverse event profiles were comparable between treatments. CONCLUSION Over 12 months, Gla-300-treated participants achieved sustained glycaemic control and experienced less hypoglycaemia, particularly at night, versus Gla-100, supporting 6-month results.

Abstract
BACKGROUND AND PURPOSE Although skull fractures are generally assessed on bone images obtained by using head CT, the combined multikernel technique that enables evaluation of both brain and bone through a change in the window settings of an image set has been reported. The purpose of this retrospective study was to determine the image quality required for the accurate assessment of skull fractures by using head CT. MATERIALS AND METHODS A random sample of 50 patients (25 nonfracture and 25 simple nondisplaced skull fractures) was selected, and sets of conventional brain and bone images and improved combined multikernel images were reconstructed (4614 images). Three radiologists indicated their confidence levels regarding the presence of skull fractures by marking on a continuous scale for each image set. The mean area under the receiver operating characteristic curve was calculated for each kernel, and the statistical significance of differences was tested by using the Dorfman-Berbaum-Metz method. RESULTS Although a difference in the diagnostic performance of the 3 radiologists was suggested, the mean area under the curve value showed no significant differences among the 3 reconstruction kernels (P = .95 [bone versus combined]), P = .91 [bone versus brain]), and P = .88 [brain versus combined]). However, the quality of brain images was distinctly poorer than the quality of the other 2 images. CONCLUSIONS There was no significant difference in the diagnostic performance of brain, bone, and combined multikernel images for skull fractures. Skull fracture diagnosis is made possible by brain image assessments. Combined multikernel images offer the advantage of high-quality brain and bone images.

Abstract
AIMS To compare the efficacy and safety of insulin glargine 300 U/ml (Gla-300) with glargine 100 U/ml (Gla-100) in Japanese people with type 2 diabetes using basal insulin plus oral antihyperglycaemic drug(s) [OAD(s)]. METHODS The EDITION JP 2 study (NCT01689142) was a 6-month, multicentre, open-label, phase III study. Participants (n = 241, male 61%, mean diabetes duration 14 years, mean weight 67 kg, mean body mass index 25 kg/m(2), mean glycated haemoglobin (HbA1c) 8.02 %, mean basal insulin dose 0.24 U/kg/day) were randomized to Gla-300 or Gla-100, while continuing OAD(s). Basal insulin was titrated to target fasting self-monitored plasma glucose 4.4-5.6 mmol/l. The primary efficacy endpoint was HbA1c change over 6 months. Safety endpoints included hypoglycaemia and weight change. RESULTS Gla-300 was non-inferior to Gla-100 for HbA1c reduction [least squares (LS) mean difference 0.10 (95% confidence interval [CI] -0.08, 0.27) %]. The mean HbA1c at month 6 was 7.56 and 7.52 % with Gla-300 and Gla-100, respectively. Nocturnal confirmed (≤3.9 mmol/l) or severe hypoglycaemia risk was 38% lower with Gla-300 versus Gla-100 [relative risk 0.62 (95% CI 0.44, 0.88)]; annualized rates were 55% lower at night [rate ratio 0.45 (95% CI 0.21, 0.96)] and 36% lower at any time [24 h; rate ratio 0.64 (95% CI 0.43, 0.96)]. Severe hypoglycaemia was infrequent. A significant between-treatment difference in weight change favoured Gla-300 [LS mean difference -1.0 (95% CI -1.5, -0.5) kg; p = 0.0003]. Adverse event rates were comparable between groups. CONCLUSIONS Japanese people with type 2 diabetes using basal insulin plus OAD(s) experienced less hypoglycaemia with Gla-300 than with Gla-100, while glycaemic control did not differ.

Abstract
AIM To compare efficacy and safety of new insulin glargine 300 U/ml (Gla-300) with that of insulin glargine 100 U/ml (Gla-100) in Japanese adults with type 1 diabetes. METHODS The EDITION JP 1 study (NCT01689129) was a 6-month, multicentre, open-label, phase III study. Participants (n = 243) were randomized to Gla-300 or Gla-100 while continuing mealtime insulin. Basal insulin was titrated with the aim of achieving a fasting self-monitored plasma glucose target of 4.4-7.2 mmol/l. The primary endpoint was change in glycated haemoglobin (HbA1c) over 6 months. Safety measures included hypoglycaemia and change in body weight. RESULTS Gla-300 was non-inferior to Gla-100 for the primary endpoint of HbA1c change over the 6-month period {least squares [LS] mean difference 0.13 % [95 % confidence interval (CI) -0.03 to 0.29]}. The annualized rate of confirmed (≤3.9 mmol/l) or severe hypoglycaemic events was 34 % lower with Gla-300 than with Gla-100 at night [rate ratio 0.66 (95 % CI 0.48-0.92)] and 20 % lower at any time of day [24 h; rate ratio 0.80 (95 % CI 0.65-0.98)]; this difference was most pronounced during the first 8 weeks of treatment. Severe hypoglycaemia was infrequent. The basal insulin dose increased in both groups (month 6 dose: Gla-300 0.35 U/kg/day, Gla-100 0.29 U/kg/day). A between-treatment difference in body weight change over 6 months favouring Gla-300 was observed [LS mean difference -0.6 kg (95 % CI -1.1 to -0.0); p = 0.035]. Adverse event rates were comparable between the groups. CONCLUSIONS In Japanese adults with type 1 diabetes using basal plus mealtime insulin, less hypoglycaemia was observed with Gla-300 than with Gla-100, particularly during the night, while glycaemic control did not differ.

Abstract
A 15-year-old girl was found to be hypertensive (230-270/140-170 mm Hg) without any subjective symptoms. Magnetic resonance imaging confirmed the presence of a well-defined 22 mm hypodense lesion in the lower pole of the left kidney, located close to the renal hilum. Plasma rennin activity was elevated (75 ng/mL/h), and reninoma was diagnosed. Retroperitoneoscopy-assisted nephron-sparing surgery was planned. The retroperitoneum was accessed through a 4 cm left pararectal upper abdominal incision. Following blunt dissection, the abdominal wall was elevated with a lifting bar and lifting retractor, inserted below the 12th rib in the anterior axillary line to create sufficient working space in the retroperitoneal cavity without the need for pneumoperitoneum. Three 5 mm trocars were introduced above the superior iliac crest for the camera and the assistant. Gerota's fascia was opened and the kidney exposed. The surgeon dissected the left kidney through the minilaparotomy incision under both direct vision and using the magnified view on the monitor, which was particularly effective for the lateral and posterior sides of the kidney. The posterior peritoneum was incised intentionally next to the diaphragm to allow further mobilization of the kidney. Diathermy was used to remove the tumor and a layer of surrounding normal parenchymal tissue at least 0.5 cm thick. The histopathologic diagnosis was reninoma. Ischemia time was 14 minutes. Postoperatively, both plasma rennin activity and blood pressure were normal (1.9 ng/mL/h and 90-110/70-80 mm Hg, respectively). After follow-up of 12 months, there is no evidence of recurrence.

Abstract
This study presents a modified surgical approach to laparoscopic myotomy for achalasia using stepped dilation with a Rigiflex balloon and contrast medium under image guidance. A 10-year-old boy with persistent dysphagia and vomiting had ingested only liquids for 3 months, losing >10 kg in body weight. Barium swallow and esophageal manometry diagnosed esophageal achalasia with mild esophageal dilatation. After failed pneumatic dilatation, laparoscopic Heller myotomy with Dor fundoplication was performed. Prior to surgery, a Rigiflex balloon dilator was placed within the esophagus near the diaphragmatic hiatus. A four-port technique was used, and mobilization of the esophagus was limited to the anterior aspect. A 5-cm Heller myotomy was performed, extending another 2 cm onto the anterior gastric wall. During myotomy, the Rigiflex balloon was serially dilated from 30 to 50 mL, and filled with contrast medium under fluoroscopic image guidance in order to maintain appropriate tension on the esophagus to facilitate myotomy, and to confirm adequate myotomy with sufficient release of lower esophageal sphincter by resecting residual circular muscle fibers. Residual circular muscle fibers can be simultaneously visualized under both fluoroscopic image guidance and direct observation through the laparoscope, and they were cut precisely until the residual notch fully disappeared. Dor fundoplication was completed. The operative time was 180 minutes, and oral intake was started after esophagography on postoperative day 1. As of the 12-month follow-up, the patient has not shown any symptoms, and his postoperative course appeared satisfactory.

Abstract
BACKGROUND The purpose of this study was to investigate fetal cardiac ultrasonographic parameters in relation to the outcomes of patients with isolated left-sided congenital diaphragmatic hernia (CDH). METHODS Subjects comprised 33 fetuses with fetal CDH and 99 control fetuses without cardiac and lung anomalies. Three parameters, cardiothoracic area ratio (CTAR), the ratio of the diameter of the main pulmonary artery to that of the ascending aorta (MPA/AAo), and the ratio of the diameter of the tricuspid valve to that of the mitral valve (TV/MV) were compared between fetal CDH and control subjects and between survival (SG) and non-survival (NSG) groups. RESULTS All three parameters differed significantly between CDH and control fetuses. Significant differences between SG and NSG were observed in CTAR and TV/MV ratio, but not in MPA/AAo ratio before and after 32 gestational weeks. A significant increase in the TV/MV ratio was noted along with an increase in gestational age. A TV/MV ratio of >1.72 discriminated non-survivors from survivors with better sensitivity and specificity. CONCLUSIONS Fetal cardiac ultrasonography provides useful information for predicting the outcomes of isolated left-sided CDH. The TV/MV ratio was considered a reliable indicator that reflected outcomes of isolated left-sided CDH.

Abstract
We describe a novel technique for laparoscopic hepatic ductoplasty and hepaticojejunostomy in choledochal cyst with a narrow common hepatic duct. After complete cyst excision, a longitudinal incision was made in the anterior wall of the narrow common hepatic duct to enlarge the anastomotic opening. Next, the anterior wall was everted, then anchored to the hepatic hilum by suturing. Anchoring of the anterior wall provided a good field of view for creating the anastomosis, and the lumen of the anastomotic region was also secured. We believe that our technique is feasible and useful when the duct size is small.

Abstract
PURPOSE To present the medium to long-term outcome of the largest pediatric series of laparoscopic Toupet fundoplications (LTF) performed at a single institution. PATIENTS AND METHODS Subjects were 131 neurologically impaired children (81 M, 50 F) who underwent LTF between 2003 and 2013. Our LTF involves full dissection of the crus of the diaphragm to allow the intraabdominal esophagus to be mobilized at least 3-4 cm. RESULTS Preoperative mean fraction time for pH <4 was 14.6 %. Mean age at LTF was 6.7 years (3 months-18 years). Mean duration of follow-up was 5.7 years (range 1.2-12.1 years). One case required conversion to open surgery. Intra-operative complications were all injuries to the esophagus/gastric wall (n = 4; 3.0 %) including full-thickness perforation (n = 1; 0.8 %). Postoperative complications included pyloric stenosis (n = 4; 3.0 %), dysphagia (n = 1; 0.8 %), incisional hernia (n = 1; 0.8 %), hemorrhage requiring transfusion (n = 1; 0.8 %), recurrence (n = 3; 2.3 % at 11, 13, and 48 months, respectively), and gastrostomy site infection (n = 7; 5.3 %). Mean operative time decreased significantly with experience from 180.8 min for the first quarter of subjects to 150.6 (2nd quarter), 128.6 (3rd) and 109.2 min (4th). CONCLUSIONS Our LTF would appear to be safe for treating GERD in children because of reliable outcome and low recurrence.

Abstract
INTRODUCTION We report a case of a 1.8-kg infant who had laparoscopic Toupet fundoplication (LTF) using the AirSeal Intelligent Flow System and Anchor Port (AP). MATERIALS AND SURGICAL TECHNIQUE Our case had severe gastroesophageal reflux in association with genetic and cardiac anomalies. Despite the patient being continuously fed, persistent vomiting caused failure to thrive, and LTF was performed at 4 months of age when he weighed 1.8 kg. The AirSeal Intelligent Flow System is a novel laparoscopic CO2 insufflation system that improves the visual field by constantly evacuating smoke and providing a more stable pneumoperitoneum. The AP is a recently developed, stretchable, elastomeric, low-profile cannula. Three 5-mm AP were inserted: one subumbilically for the scope and one in both the right and left upper abdomen for the surgeon. A 5-mm AirSeal trocar was inserted in the left lower abdomen for the assistant. The gastrosplenic ligament was dissected free, and the intra-abdominal esophagus was prepared. A posterior hiatoplasty was performed, followed by the 270° fundoplication. During the fundoplication, the esophagus was fixed to the crus and then the right and left wraps were fixed to the esophagus. Pneumoperitoneum was maintained stably throughout the LTF procedure, with optimal operative field. Total operating time for LTF was 90 min. Body temperature dropped from 37.4°C to 35.7°C during pneumoperitoneum but resolved once pneumoperitoneum was ceased. Postoperative progress was uneventful, and an upper gastrointestinal study on postoperative day 2 showed no residual gastroesophageal reflux. DISCUSSION We believe the AirSeal Intelligent Flow System and AP contributed to the successful completion of LTF in a 1.8-kg infant.

Abstract
OBJECTIVE To investigate time intervals of the ductus venosus (DV) flow velocity waveform (FVW) and those of the cardiac cycle that correspond with each DV-FVW component in fetuses with intrauterine growth restriction (IUGR) due to placental insufficiency. METHODS Women with a pregnancy complicated by IUGR were recruited into the study, as was a normal control group. Time intervals for systolic (S) and diastolic (D) components were measured in DV-FVW as follows: S(DV), from the nadir of the a-wave during atrial contraction to the nadir between the S-wave and D-wave; D(DV), from the nadir between S-wave and D-wave to the nadir of the a-wave. Regarding cardiac cycles, the following variables were measured from ventricular inflow through the tricuspid valve (TV) and mitral valve (MV): S(TV) and S(MV), from the second peak of ventricular inflow caused by atrial contraction (A-wave) to the opening of the atrioventricular valve; D(TV) and D(MV), from the opening of the atrioventricular valve to the peak of the A-wave. In the IUGR group, only the last examination performed within 1 week of delivery was used for analysis. All variables were analyzed statistically using Z-scores. RESULTS Data were obtained from 249 normal fetuses and 26 fetuses with IUGR. Compared to normal fetuses, S(DV) showed a significant decrease (P < 0.001), while D(DV) showed a significant increase (P < 0.001) in the IUGR group. Regarding cardiac cycles, S(TV) and S(MV) showed significant decreases (P = 0.014 and P < 0.001, respectively) and D(TV) and D(MV) showed significant increases (P = 0.008 and P = 0.002, respectively) in fetuses with IUGR. CONCLUSION Time-interval alterations of DV-FVW in growth-restricted fetuses reflect the hemodynamic events caused by placental insufficiency.

Abstract
We report herein an adolescent case of Duchenne muscular dystrophy (DMD) with idiopathic gastric perforation, in which emergency surgical repair was performed laparoscopically. A 14-year-old nonambulatory boy with DMD was brought to our emergency department with sudden onset of severe abdominal pain and distention. Plain radiograph and computed tomography confirmed the presence of free intraperitoneal air and intrapelvic effusion. The patient elected to undergo laparoscopic inspection with 4 trocars, revealing a focal perforation, 3-4 cm in diameter, on the upper gastric body near the diaphragm. The stomach was also found to have a thin wall without evidence of peptic ulcer disease or other abnormalities. An interrupted suture was placed using 4-0 PDS. The abdomen was extensively irrigated, and multiple J-Vac drains were left in situ. Total operation time was 90 min, and no intraoperative complications were encountered. Enteral feeding through a nasogastric tube was started on postoperative day 7. The postoperative course has been uneventful as of the 12-month follow-up. Pediatric surgeons should be aware of the increased risk of gastric perforation associated with DMD, and that laparoscopic repair can be safely performed even in emergency settings.

Abstract
OBJECTIVES To investigate time-interval variables of ductus venosus (DV) flow velocity waveforms (FVWs) in twin-to-twin transfusion syndrome (TTTS), comparing the results with reference ranges from normal singleton fetuses. The impact of laser surgery and the effect of prognostic factors were also evaluated. METHODS In 107 TTTS cases, DV-FVWs of both recipients and donors were recorded 1 day before and 2 days after laser therapy. Time intervals for systolic (S) and early diastolic (D) peaks were analyzed retrospectively with regard to acceleration time (acc-S and acc-D for S and D, respectively) and deceleration time (dec-S and dec-D for S and D, respectively). For each variable, Z-scores were calculated with respect to previously reported normal reference ranges. RESULTS Z-scores for all variables showed statistically significant differences from those observed previously in normal fetuses, with the exception of dec-S of donors. The most striking differences were observed in longer dec-S of recipients (P < 0.001) and longer dec-D of donors (P < 0.001). Laser therapy showed significant impact on dec-S and acc-D in recipients and on all variables in donors. Regarding the short-term prognosis, acc-S and dec-S showed significant differences for the prediction of intrauterine fetal demise in donors (P = 0.009 and P = 0.011, respectively). CONCLUSION This study demonstrates that time-interval variables of DV-FVWs may differentiate the characteristic hemodynamic changes caused by unbalanced blood volume between recipients and donors.

Abstract
INTRODUCTION In children with choledochal cysts (CC), obstruction of the discharge of bile or pancreatic juice is frequently observed, and biliary perforation and severe pancreatitis may occur. In such cases, temporary drainage is necessary to stabilize these patients. We employed laparoscopic cholecystostomy followed by laparoscopic cyst excision in cases with complicated CC. METHODS Between 2009 and 2013, emergency laparoscopic cholecystostomy for bile drainage was performed in seven girls with complicated CC in whom conservative treatment failed to ameliorate abdominal pain, vomiting, and jaundice; among these seven patients included two with biliary perforation, one with a huge cyst, and four with peribiliary edema suggestive of impending biliary rupture. Protein plugs in the common channel or the terminal portion of the cyst were present in six patients. RESULTS Amelioration of symptoms, such as abdominal pain and jaundice, was achieved in all patients after laparoscopic cholecystostomy. Saline irrigation of the bile duct via cholecystostomy was commenced 2 days postoperatively. All patients underwent laparoscopic cyst resection after improvement of their general condition and detailed evaluation of the intrahepatic and extrahepatic bile ducts and pancreaticobiliary maljunction. Impacted protein plugs or gallstones were eliminated in all patients by the time of laparoscopic cyst excision. CONCLUSION Laparoscopic cholecystostomy followed by laparoscopic cyst excision is a useful and safe procedure for the treatment of complicated CC. This technique is also favorable from a cosmetic viewpoint because the resultant wound can be reused as the trocar insertion site at the time of laparoscopic cyst excision.

Abstract
AIM To determine the best way to perform diaphragmatic plication for diaphragmatic eventration (DE) using minimally invasive surgery. MATERIALS AND METHODS We conducted a retrospective review of pediatric cases of DE treated between 2007 and 2012. Thoracoscopic plication (TP) is performed using single-lung ventilation with three 5-mm ports; laparoscopic plication (LP) is performed using three or four 5-mm ports. The choice of technique was determined preferentially by the treating surgeon. RESULTS There were 20 subjects (13 treated by LP and 7 treated by TP). Etiology of DE was phrenic nerve injury (LP, n=11; TP, n=1) and muscular deficiency (LP, n=2; TP, n=6). Mean age (LP, 18 months; TP, 25 months) and weight (LP, 8.0 kg; TP, 9.7 kg) at surgery were not significantly different. Mean operating time was 155.6 minutes in LP and 167.0 minutes in TP (P=not significant). Mean intraoperative end-tidal CO2 was 41.9 mm Hg (range, 35-52 mm Hg) in LP and 36.9 mm Hg (range, 33-41 mm Hg) in TP (P=.01). Mean duration of postoperative ventilation was 1.2 days in LP and 1.3 days in TP (P=not significant). Mean time taken to recommence feeding postoperatively was 1.6 days in both groups (P=not significant). Complications were one conversion to thoracotomy in TP, 1 case of atelectasis in each group (P=not significant), and 6 cases of recurrence in LP versus none in TP (P=.04). CONCLUSIONS Both TP and LP are beneficial for treating small children with DE. However, there is a higher incidence of recurrence after LP, and the role of TP in cardiac patients requiring subsequent surgery is debatable.

Abstract
AIMS Two single-dose studies were conducted in Japan and Europe to compare the pharmacokinetic (PK) and pharmacodynamic (PD) profiles of new insulin glargine 300 U/ml (Gla-300) and insulin glargine 100 U/ml (Gla-100) in people with type 1 diabetes mellitus. METHODS In two double-blind, randomized, crossover studies, 18 Japanese participants (aged 20-65 years) and 24 European participants (aged 18-65 years) with glycated haemoglobin levels ≤9.0% (≤75 mmol/mol) received single subcutaneous doses of Gla-300, 0.4, 0.6 and 0.9 U/kg (0.9 U/kg in the European study only), and Gla-100, 0.4 U/kg. A 36-h euglycaemic clamp procedure was performed after each dosing. RESULTS The serum insulin glargine concentration (INS) and glucose infusion rate (GIR) developed more gradually into more constant and prolonged profiles with Gla-300 than with Gla-100. In support of this, the times to 50% of glargine exposure and insulin activity were longer for all Gla-300 doses than for Gla-100 during the 36-h clamp period, indicating a more evenly distributed exposure and metabolic effect beyond 24 h. Exposure to insulin glargine and glucose utilization were lower with the 0.4 and 0.6 U/ml Gla-300 doses in both studies compared with the 0.4 U/ml Gla-100 dose. Glucose-lowering activity was detected for up to 36 h with all doses of Gla-300. CONCLUSIONS Single-dose injections of Gla-300 present more constant and prolonged PK and PD profiles compared with Gla-100, maintaining blood glucose control for up to 36 h in euglycaemic clamp settings in Japanese and European participants with type 1 diabetes.
