Cardiovascular risk factors associated with pulse pressure in a screened cohort in Okinawa, Japan.

We evaluated the association between pulse pressure (PP) and cardiovascular risk factors in a screened cohort. Individuals who were receiving medications for hypertension or heart disease, who had no ECG record, or who had a record of arrhythmia were excluded. In total, 8,508 subjects (5,299 men and 3,209 women; age range, 18 to 89 years) were studied. Subjects were divided into four PP classes: PP.1 (PP < or = 40 mmHg, n=2,127), PP.2 (40 < or = PP < or = 44 mmHg, n=2,127), PP.3 (44 < or = PP < or = 50 mmHg, n=2,127) and PP.4 (50 mmHg < or = PP, n=2,127). Multiple regression analysis was used for evaluating the association between PP and cardiovascular risk factor or lifestyle. In men, the regression coefficient was 0.27 for age, 2.50 for diabetes mellitus, 0.33 for uric acid, 0.20 for body mass index, 0.07 for heart rate, -0.83 for current smoking habit and 1.23 for habitual drinking. In women, the regression coefficient was 0.37 for age, 4.09 for diabetes mellitus, 0.42 for body mass index, 0.14 for heart rate, and 0.84 for habitual exercise. In both men and women, PP was significantly increased in association with an increase in the number of risk factors (diabetes mellitus, obesity, current drinking status, heart rate, and hyperuricemia). In conclusion, higher PP was associated with cardiovascular risk factors. These associations were similar in both men and women.     

Molecular diagnosis and characterization of a culture-negative mycotic aneurysm due to ST54 Haemophilus influenzae type b with PBP 3 alterations

Mycotic aneurysm is a rare but life-threatening disease that warrants an integrated therapeutic approach involving surgical intervention and prolonged antibiotic use. However, the causative organisms are often unidentified because antibiotics started empirically render blood and tissue cultures negative. Molecular diagnosis has been reported to be useful in such culture-negative cases. We report a case of a culture-negative mycotic aortic aneurysm due to Haemophilus influenzae, diagnosed by direct 16S rRNA polymerase chain reaction (PCR) and sequencing of the resected aneurysm tissue. PCR for serotype revealed type b, and PCR and sequencing of the ftsI gene revealed alterations in penicillin-binding protein 3, suggesting resistance to ampicillin. Multilocus sequence typing demonstrated that the isolate belonged to sequence type 54.

Hobson’s choice two-stage hepatectomy for multiple and bilobar colorectal liver metastases with portal vein embolization: report of two cases

Liver resection is recognized as the preferred treatment for patients with colorectal liver metastases (CLM) because it offers long-term survival; it is the only hope for a cure. However, in the majority of cases, liver surgery is contraindicated due to the small volume of the future remnant liver. To extend the surgical indications for CLM, a planned two-stage hepatectomy procedure with portal vein embolization (PVE) was developed specifically for patients with multiple and bilobar CLM. The rationale for performing the procedure was a concern about the possible overgrowth of intrafuture remnant liver lesions following PVE, and it was therefore recommended for all multiple bilobar CLM cases, even when one-stage hepatectomy was technically feasible. We recently performed Hobson’s choice two-stage hepatectomy in two cases for reasons different from those of the original planned two-stage hepatectomy. In the present report, we describe our Hobson’s choice two-stage hepatectomy strategy, which provided favorable short-term outcomes.     

A multi-disciplinary distributed simulation environment for mechatronic system design enabling hardware-in-the-loop simulation based on HLA

This paper proposes a high-level architecture-based multi-disciplinary distributed simulation environment for designing mechatronic systems. In the system, commercial off-the-shelf simulators can communicate each other via real-time-infrastructure to realize software-in-the-loop simulation. Moreover, hardware prototypes can also participate in a part of the distributed simulation environment which enable us hardware-in-the-loop simulation. Effectiveness was verified by applying the environment to mechatronic system design of an automotive power-window and an omni-directional electric wheel chair.
