Abstract
INTRODUCTION The current treatment for heart disease consists of exercise therapy in addition to pharmacotherapy, nutritional support and lifestyle guidance. In general, nutritional support focuses on protein, salt and energy restrictions, with no active protein or amino acid intake in cases involving moderate or higher renal failure. From this perspective, patients with cardiac disease are at high risk of frailty.Beta-hydroxy beta-methyl butyrate (HMB) is a metabolite of leucine. HMB is widely used for muscle strengthening and can be safely ingested even by patients with renal failure. The proposed study protocol will investigate the effects of HMB-calcium (HMB-Ca) administered in combination with comprehensive cardiac rehabilitation for muscle strength, muscle mass and cardiac function in patients with cardiac disease during the convalescent period. The primary outcome will be knee extensor strength. Secondary outcomes will be gross isometric limb strength and skeletal muscle mass. METHODS AND ANALYSIS This study will be a single-blinded, randomised, controlled trial with parallel comparisons between two groups. The study period will be 60 days from the start of outpatient cardiac rehabilitation. Participants will be randomly divided into two groups: an HMB group consuming HMB-Ca one time per day for 60 days; and a Placebo group consuming reduced maltose once one time per day for 60 days. Exercise therapy will be performed by both groups. ETHICS AND DISSEMINATION The study protocol will be published in a peer-reviewed journal. Ethics approval was provided by the Showa University Clinical Research Review Board. TRIAL REGISTRATION NUMBER jRCTs031220139; Japan Registry of Clinical Trails.

Abstract
BACKGROUND Early reported beneficial effects of cardiac rehabilitation (CR) have recently been disputed. The present study aimed to investigate the clinical impact of CR on the mid-term outcomes of patients following ST-segment elevation myocardial infarction (STEMI) treated with currently available management. METHODS This study reviewed 145 consecutive patients who underwent primary coronary intervention and were discharged without any disability after STEMI during 2013-2015. RESULTS Among the patients, 66 (45.5%) completed an outpatient CR program (CR group) and 79 were their non-CR counterparts or patients who dropped out of the program (N-D group). There were no between-group differences in patient demographics and clinical profiles, including door-to-balloon times and prescriptions. A total of 27 patients developed major adverse cardiac and cerebrovascular events (MACCE) during follow-up. The MACCE-free survival rates were 88% and 76% in the CR and N-D groups, respectively (log-rank, p=0.04). Cox proportional analysis demonstrated that inclusion in the N-D group was a significant predictor of MACCEs (HR, 2.36; 95% CI, 1.07-5.74; p=0.03). In the CR group, peak oxygen consumption and ventilatory efficiency determined by cardiopulmonary exercise testing significantly improved after the program (p<0.01). CONCLUSIONS The impact of CR on the mid-term prognosis of patients with STEMI, even in the current myocardial infarction management era, was beneficial.

Abstract
Objectives: In the field of exercise physiology, there has been great interest in exploring circulating microRNAs (miRs) as potential biomarkers. However, it remains to be determined whether circulating miRs reflect cardiorespiratory fitness. The aim of this study was to investigate the association between circulating levels of specific miRs and cardiorespiratory fitness evaluated by cardiopulmonary exercise testing (CPET) after acute myocardial infarction (MI). Methods: Twenty patients who had had an acute MI were included. All patients underwent CPET in the convalescent phase. Quantitative real-time polymerase chain reaction analyses for miR-181 members (a/b/c) and miR-484 were performed to determine the expression levels in the peripheral blood of the included patients and healthy control subjects (n=5). Results: Post-MI patients showed impaired exercise tolerance and ventilatory efficiency in CPET analysis. Compared with controls, circulating levels of miR-181a and 181c were gradually and significantly elevated through the 1st to 7th days after acute MI, whereas miR-181b and miR-484 were not. Circulating miR levels did not correlate with clinical or echocardiographic parameters. However, circulating levels of miR-181c and miR-484 on the 7th day showed significant positive correlations with the anaerobic threshold and peak oxygen consumption from CPET analysis. Moreover, miR-181c levels were inversely associated with the ventilatory inefficiency index. Patients with high exercise capacity after MI showed significantly higher expressions of circulating miR-181c and miR-484 than those with low exercise capacity. Conclusions: The results of this pilot study suggest that circulating levels of miR-181c and miR-484 after acute MI may be predictive biomarkers of post-MI cardiorespiratory fitness.

Abstract
Pancreaticojejunal anastomotic leakage is one of the severe complications after pancreaticoduodenectomy and is often difficult to manage. A 64-year-old man status post pancreaticoduodenectomy had the gastroduodenal artery stump bleeding caused by the pancreaticojejunal anastomotic leakage, successfully treated by placing a covered stent. To control the leakage, subsequent percutaneous transgastric pancreatic duct puncture was performed under fluoroscopic guidance, targeting a surgically placed pancreaticojejunal internal drainage catheter. A 5 F catheter with side holes was inserted into the main pancreatic duct, the tip of which was placed in the anastomosed jejunum. The leak was successfully treated using this catheter. Percutaneous transgastric pancreatic duct drainage might be a useful and feasible option to resolve the condition.

Abstract
We report a case of a 31-year-old healthy man with marathon-induced pulmonary edema. Chest radiograph revealed pulmonary edema without cardiomegaly. Contrast-enhanced chest computed tomography (CT) revealed transient pulmonary edema without filling-defect in pulmonary arteries. As marathon running increases in popularity, radiologists and emergency physicians should be familiar with diagnosis of this entity on chest radiograph, avoiding unnecessary CT examination without additional clinical information.

Abstract
Myelodysplastic syndromes (MDS) are characterized by proliferation and apoptosis of bone marrow cells. Minichromosome maintenance protein (MCM) 2, which is known to be essential for regulating DNA replication, has proven to have a pro-apoptotic effect in our recent study. Thus, to determine the role of MCM2 in MDS, real-time PCR, immunohistochemistry and in vitro analysis were performed. Our results showed higher MCM2 expression in MDS than in control and AML. Notably, there was no correlation between MCM2 and Ki67-labeling indices (LIs) in MDS, while MCM2 LIs were significantly correlated with cleaved caspase 3 LIs in MDS. In vitro analysis revealed that MCM2 overexpression induced apoptosis in HL60 cells. Furthermore, MDS bone marrow exhibited higher ratio of MCM2 and cleaved caspase 3 double-positive cells and the ratio was correlated with the degree of leukocytopenia. These results suggest that the up-regulated expression of MCM2 is associated with frequent apoptosis in MDS and may have an important role in the pathogenesis of MDS.

Abstract
AIM Previous studies showed that HL-350, a formula thickened with a reduced concentration of locust bean gum, decreased frequent regurgitation in 4-month old infants with reflux. In this study, we investigated the effect of HL-350 in younger infants. METHODS We studied 20 infants less than 2 months old who had three or more episodes of regurgitation or vomiting per day. Ten infants (group A) were fed with HL-350 for the first week, and with control milk, HL-00, for the following week. The other 10 infants (group B) were fed in reverse order. Mothers recorded number of regurgitation episodes, feeding volume and time and number of bowel movements. To evaluate gastric emptying we measured antral cross sectional areas ultrasonographically at various time points after feeding. RESULTS The median number of regurgitation episodes decreased significantly with feeding of HL-350 (2.3/day) compared to feeding with control milk (5.2/day) (p = 0.00048). No significant difference was evident in feeding volume and time, body weight gain, or gastric emptying rate between HL-350 and control milk. CONCLUSION HL-350 decreased the number of regurgitation episodes without affecting gastric emptying delay in very young infants with recurrent vomiting.

Abstract
We report an 11-year-old girl with acute disseminated encephalomyelitis (ADEM) who developed respiratory failure and coma despite the use of corticosteroid and intravenous immunoglobulin. We performed plasmapheresis four times, which improved her level of consciousness, hyperesthesia, external ophthalmoplegia and muscle weakness, and led to the normalization of brain and spinal cord MRI. Plasmapheresis might be an effective treatment in cases of fulminant ADEM.

Abstract
The treatment points and score for definition of the asthma severity were initially introduced in the guideline for pediatric asthma treatment and management on 1998. We studied the relationship between the severity of clinical symptoms for children with bronchial asthma and the treatment points from July 1998 to November 1999 in our hospital. One hundred twenty five patients (one to 15 years of age, 77 boys and 48 girls) were retrospectively investigated. The treatment points and scores were associated with the clinical symptom score. However, there was no relationship in some patients. In order to define the severity of bronchial asthma, we should investigate not only the severity in terms of the clinical symptoms; the number and degree of asthma attacks, but also the treatment points and score. Furthermore, we should pay attention to the seasonal variation of the treatment points.

Abstract
There have been very few postoperative follow-up studies from the aspect of philosophical anthropology in the field of pediatric surgery. Fifty patients who underwent surgery either during the neonatal period or infancy and have been receiving medical treatment or consultation for more than 20 years in Juntendo University Hospital and Katsunan Hospital, were investigated from the aspect of philosophical anthropology. During adolescence or young adulthood, 52% of the patients were suffering from their medical problems. Forty percent of patients were bullied by their peers during their elementary school age due to various medical problems. As patients became adolescents or young adults, 20% of them started to feel that others were prejudiced against them or they were discriminated against when going to school or looking for a job. About 30% of patients who were of elementary school age and of adolescent or adult age, were introverted and short-tempered. Eighteen percent of the patients who were of elementary school age and adolescent or young adult age, were not satisfied with their family, particularly their parents, because of their medical problems. When patients became adults, 40% were not satisfied with their own society, particularly with others in their working place. More than 80% of patients who were of preschool age were shielded from their medical problems by their parents. As they became older, their parents were not always able to cover up their medical problems, but understanding school teachers and their elders were able to shield some of patients from social ridicule. By learning the results of this study, it is important for pediatric surgeons to minimize postoperative medical problems, giving proper surgery and postoperative care. Pediatric surgeons should become very supportive medical doctors to patients who suffer from postoperative medical problems.
