Significant but weak spousal concordance of metabolic syndrome components in Japanese couples

Objective

This study was initiated to investigate if spousal concordance in metabolic syndrome (MS) components exist in Japan.

Methods

In all, 756 couples (mean age: 48.9 and 47.3 years for husbands and wives, respectively) were identified. Each subject was classified as an MS, MS reserves (MSRES) or no risk of MS (NonMS) case after Japanese Ministry of Health, Labour and Welfare (JMHLW) criteria. Criteria of the National Cholesterol Education Program and of the Joint Interim Statement were also applied.

Results

With Japanese Ministry of Health, Labor and Welfare (JMHLW) criteria, MS, MSRES and NonMS cases accounted for 11.9, 14.7 and 73.4 % in husbands and 1.6, 3.7 and 94.7 % in wives. Waist circumference (WC), body mass index (BMI), systolic blood pressure (SBP) and hemoglobin A1c (HbA1c) showed significant correlation (p < 0.01). Correlation was also significant (p < 0.05) for mean blood pressure (MBP) and fasting plasma glucose (FPG). When adjusted for age, correlations were significant only for WC, BMI and HbA1c. Furthermore, none of the correlation coefficients were greater than 0.2. Logistic regression analyses did not suggest significant mutual influence in MS status between the couples.

Conclusions

Spousal concordance in MS components was detected for WC, BMI, SBP, MBP, FPG and HbA1c, but the correlation was generally weak and modest in Japanese couples.

Clinical efficacy and treatment persistence of monthly minodronate for osteoporotic patients unsatisfied with,and shifted from,daily or weekly bisphosphonates: the BP-MUSASHI study

Summary

This multi-center, prospective, open-label, observational study evaluated the effects of once-monthly minodronate (50 mg) on treatment persistence, bone turnover markers, bone mineral density, low back pain, and upper gastrointestinal symptoms in outpatients with osteoporosis previously treated with daily or weekly bisphosphonate products.

Introduction

The purposes of this study were to investigate the effects of once-monthly oral minodronate (MIN 50 mg) on bone turnover markers and bone mineral density, low back pain, and upper gastrointestinal symptoms, as well as preference for and treatment persistence of MIN 50 mg among Japanese osteoporosis patients currently treated with daily or weekly bisphosphonates.

Methods

Study patients were allocated based on their preference to either the Switch group (patients willing to switch over to MIN 50 mg) or the Continue group (patients wanting to continue their current therapies). Patients’ treatment persistence and satisfaction levels with the therapies were assessed using a self-administered questionnaire. The study endpoints were serum TRACP-5b, serum P1NP, bone mineral density, upper gastrointestinal symptoms, and low back pain.

Results

In total, 264 and 133 patients were allocated into the Switch and Continue groups, respectively. Approximately, 65 % of patients were willing to switch to MIN 50 mg, with the predominant reason being “less frequent dosing more convenient.” Treatment persistence was significantly higher in the Switch group (MIN 50 mg) than the Continue group. Almost all patients with abnormal bone metabolism markers demonstrated normalization after switchover. MIN 50 mg alleviated low back pain and upper gastrointestinal symptoms induced by prior bisphosphonate use.

Conclusions

MIN 50 mg alleviates low back pain, reduces bone turnover markers and increases bone density, and induces fewer upper gastrointestinal symptoms after switchover from prior bisphosphonate products, and therefore, it may provide patients with a more convenient treatment option and enhance long-term treatment persistence.     

Histological features of primary tumors after induction or high-dose chemotherapy in high-risk neuroblastoma

Purpose

In the recent years in Japan, an increasing number of patients with neuroblastoma (NB) are being treated by the “delayed local treatment (DL)” policy, undergoing surgery after the completion of high-dose chemotherapy with hematopoietic stem cell rescue (HDC). We reviewed the histopathological findings of second-look operations, including those of patients treated with DL.

Patients

From 1998 to 2013, 26 patients with high-risk NB underwent radical operation following chemotherapy. Surgery was performed after induction chemotherapy in 17 cases (standard; STD), whereas 9 cases completed induction chemotherapy and HDC before undergoing tumor resection (DL). The amount of necrosis and the degree of differentiation within the post-treatment tumor were assessed.

Results

Eighty-eight percent of the tumors showed necrosis in more than 1/3 of the specimen. Two DL cases showed complete disappearance of viable tumor cells. Amount of necrosis did not affect the prognosis of the patient. Tumors with immature, poorly differentiated phenotypes showed an extremely aggressive thereafter. Though not statistically proven, ¹²³I-MIBG (metaiodobenzylguanidine) uptake may be correlated with the amount of viable cells remaining within the tumor, but not with the degree of differentiation.

Conclusions

Our results support the previous reports advocating that tumors that sustain unfavorable histology after chemotherapy behave aggressively thereafter.     

Inflammation Aggravates Heterogeneity of Ventricular Repolarization in Children With Kawasaki Disease

Kawasaki disease complicates with myocarditis and vasculitis. Even if myocarditis is asymptomatic, heterogeneity of ventricular repolarization may be increased in the acute phase. We evaluated whether the change in repolarization characteristics can be used as a predictor for myocarditis and coronary lesions. Enrolled 34 children who were treated with intravenous immunoglobulin therapy. There were no sequelae in the recovery phase in any subjects, including those who had transient coronary artery lesion. QT and the interval from the Tpeak to Tend (Tp-e) were determined. The Tp-e/QT ratios were compared between the acute and recovery phases and correlations with CRP level and body temperature were evaluated. A retrospective evaluation of Tp-e/QT as predictors of coronary dilation was also performed. Tp-e/QT in the acute phase correlated positively with body temperature and CRP level. In a comparison of patients with and without transient coronary artery lesion, Tp-e/QT was significantly higher in those with dilation. In conclusion, Tp-e/QT was strongly related to transient coronary dilation, in comparison with inflammatory indicators including fever and CRP level.     

Esophagogastric tube reconstruction with stapled pseudo-fornix in laparoscopic proximal gastrectomy: a novel technique proposed for Siewert type II tumors

Purpose

The incidence of adenocarcinoma of the esophagogastric junction is increasing, but laparoscopic proximal gastrectomy is not widely accepted due to the absence of a standardized technique of reconstruction. This report describes a novel technique of esophagogastric tube reconstruction in laparoscopic proximal gastrectomy for Siewert type II tumors.

Methods

Laparoscopic proximal gastrectomy, sometimes with transhiatal distal esophagectomy, was performed. After a perigastric, suprapancreatic, and lower thoracic paraesophageal lymphadenectomy, a gastric tube of 35-mm width was prepared. An esophagogastric tube anastomosis with pseudo-fornix was made with a no-knife linear stapler to prevent postoperative reflux esophagitis.

Results

Fifteen patients with Siewert type II tumors underwent this operation. They included six patients with early-stage cancer, six at high risk for transhiatal total gastrectomy due to several comorbidities, and three who needed palliative tumor resection. The mean operation time was 315 min. One postoperative anastomotic leak was treated conservatively, and three anastomotic stenoses were resolved with endoscopic balloon dilatation. Postoperative 1-year follow-up endoscopy revealed four cases of reflux esophagitis that were well controlled by medication.

Conclusions

This new technique of reconstruction was feasible. With the advantage of a gastric tube, a tension-free anastomosis was possible even for bulky tumors that needed lower esophagectomy. Although long-term follow-up and a larger number of patients are required to evaluate long-term functional outcomes and oncological adequacy, our procedure has the potential of becoming a treatment of choice for early-stage Siewert type II tumors and/or for some selected high-risk patients who need tumor resection.     

Blood flow distribution during heat stress: cerebral and systemic blood flow

The purpose of the present study was to assess the effect of heat stress-induced changes in systemic circulation on intra- and extracranial blood flows and its distribution. Twelve healthy subjects with a mean age of 22±2 (s.d.) years dressed in a tube-lined suit and rested in a supine position. Cardiac output (Q), internal carotid artery (ICA), external carotid artery (ECA), and vertebral artery (VA) blood flows were measured by ultrasonography before and during whole body heating. Esophageal temperature increased from 37.0±0.2°C to 38.4±0.2°C during whole body heating. Despite an increase in Q (59±31%, P<0.001), ICA and VA decreased to 83±15% (P=0.001) and 87±8% (P=0.002), respectively, whereas ECA blood flow gradually increased from 188±72 to 422±189 mL/minute (+135%, P<0.001). These findings indicate that heat stress modified the effect of Q on blood flows at each artery; the increased Q due to heat stress was redistributed to extracranial vascular beds.     

Evaluation of esophageal function in patients with gastroesophageal reflux disease using transnasal endoscopy

Background and Aims:  To investigate the utility of a new method of carrying out esophageal manometry using a narrow gauge manometry catheter via a transnasal endoscope.
Methods:  The Frequency Scale for the Symptoms of gastroesophageal reflux disease (GERD) (FSSG), a GERD-specific questionnaire, was given to 45 subjects. Subjects 
underwent transnasal endoscopy with three dry and three wet (3 mL water) swallows. Direct observations of the primary peristaltic wave and peristaltic pressure measurement were conducted simultaneously.
Results:  Endoscopic observation of lower esophageal motility associated with swallowing revealed dilatation of the esophageal lumen after swallowing, followed by contraction in association with the primary peristaltic wave. The peristaltic pressure was significantly lower with increased FSSG scores for dry swallows ( r  = −0.347, P  = 0.0212), but no significant correlation was seen for wet swallows.
Conclusions:  The significant negative correlation between reflux symptoms and peristaltic pressure in dry swallows was thought to be that reduced pressure immediately rostral to the lower esophageal sphincter leads to decreased clearance following gastric acid reflux, playing a large part in the onset of symptoms.
