Gait analysis was conducted on 7 healthy pregnant women (pregnant group) and 6 non-pregnant women (pseudo-pregnant group) using a 3-D motion analysis system (VICON 460) and two forceplates (Kistlar 9286A). The data was collected at 8-9 months of gestation (pregnant condition) and 4-8 months postpartum (non-pregnant condition) in the pregnant group. In the pseudo-pregnant group, the participants walked with a 5kg-load on their belly (pregnant condition) and without any load (non-pregnant condition). Comparisons using two-way ANOVAs with repeated measures were conducted. Interaction of group × condition was not observed in the measured gait parameters except the angle of the maximum hip adduction. Main effect in the condition and the group was found in some parameters. In the pregnant condition, gait velocity was slower (pregnant group 68.7±8.6 m/min pseudo-pregnant group 63.8±4.8 m/min) than in the non-pregnant condition (pregnant group 75.5±3.2 m/min pseudo-pregnant group 69.8±8.7 m/min). The second vertical peak ground reaction force was smaller in the pregnant condition (pregnant group 105.4±4.8 % pseudo-pregnant group 108.4±6.3 % of body-weight) than in the non-pregnant condition (pregnant group 114.3±7.4 % pseudo-pregnant group 113.5±4.2 % of body-weight). These results demonstrated that pregnant condition changed kinetic and kinematic characteristics of the gait.

PURPOSE: Peripheral artery disease (PAD) is a form of arteriosclerosis that occurs in the extremities and involves ischemia. Previous studies have reported that patients with periodontitis are at high risk for PAD. However, the relationship between these 2 diseases has not yet been fully elucidated. In this cross-sectional study, we investigated this relationship by comparing patients with PAD to those with arrhythmia (ARR) as a control group. METHODS: A large-scale survey was conducted of patients with cardiovascular disease who visited Tokyo Medical and Dental University Hospital. We investigated their oral condition and dental clinical measurements, including probing pocket depth, bleeding on probing, clinical attachment level, and number of missing teeth; we also collected salivary and subgingival plaque samples and peripheral blood samples. All patients with PAD were extracted from the whole population (n = 25), and a matching number of patients with ARR were extracted (n = 25). Simultaneously, ARR patients were matched to PAD patients in terms of age, gender, prevalence of diabetes, hypertension, dyslipidemia, obesity, and the smoking rate (n = 25 in both groups). Real-time polymerase chain reaction was performed to measure the bacterial counts, while the enzyme-linked immunosorbent assay method was used to measure anti-bacterial antibody titers and proinflammatory cytokine levels in serum. RESULTS: PAD patients had more missing teeth (18.4±2.0) and higher serum levels of C-reactive protein (1.57±0.85 mg/dL) and tumor necrosis factor-alpha (70.3±5.7 pg/mL) than ARR patients (12.0±1.7, 0.38±0.21 mg/dL, and 39.3±4.5 pg/mL, respectively). Meanwhile, no statistically significant differences were found in other dental clinical measurements, bacterial antibody titers, or bacterial counts between the 2 groups. CONCLUSIONS: Our findings suggested that PAD patients had poorer oral and periodontal state with enhanced systemic inflammation.

Purpose: In minimally invasive esophagectomy (MIE), it is important to reduce the rate of anastomotic leakage to ensure its safety. At our institute, the double-ligation method (DLM) has been introduced to insert and fix the anvil of the circular stapler for intracorporeal circular esophagojejunostomy in gastric surgery. We adopted this method for intrathoracic anastomosis (IA) in MIE. The aim of this study was to investigate the safety of IA with DLM in MIE. Methods: In this study, 48 patients diagnosed with primary middle or lower third segment thoracic esophageal carcinoma with clinical stage I, II, III or IV disease were retrospectively evaluated. Postoperative outcomes were assessed. Results: Among the 48 patients, 42 patients underwent laparo-thoracoscopic esophagectomy and IA using a circular stapler with the DLM. The average total operation time and thoracoscopic operation time were 433 and 229 minutes, respectively. The average pursestring suturing time was 4.7 minutes. The rates of anastomotic leakage and stenosis were 2.4% and 14.3%, respectively. The overall incidence of postoperative complications (ClavienDindo grade of ≥III) was 16.7%. The average postoperative stay was 16 days. Conclusion The procedure of IA using a circular stapler with the DLM in MIE was safe and provided a low rate of anastomotic leakage.

Restrictions on the use of antimicrobial agents are reported to lead to a reduction in the use of carbepanem (CP) antiobiotics and in the detection of resistant bacteria. Our hospital began monitoring the use of specific antimicrobial agents in June 2014. In the present study, we examined changes in the use of injectable broad-spectum antibiotics and in the susceptibility of Pseudomonas aeruginosa before and after introducing our antimicrobial use monitoring system (pre-and post-monitoring). We obtained a total of 301 specimens taken before the introduction of the system (January 2012-May 2014,143 specimens) and after after the introduction (June 2014-December 2016, 158 specimens). We then examined antimicrobial use density (AUD) and P. aeruginosa sensitivity per 100 patient-days.Comparisons of pre-monitoring results (2012) and post-monitoring results (2016) show that AUD decreased for imipenem/cilastatin (IPM/CS;0.26 to 0.1), meropenem (0.46 to 0.19), CAZ(0.52 to 0.16), and CZOP (0.17 to 0.09) and increased for tazobactam/piperacillin (0.67 to 1.16). Susceptibility of P. aeruginosa tended toward recovery (IPM/CS:0.8 to 0.87, piperacillin: 0.89 to 0.92, ceftazidime: 0.87 to 0.93,and cefozopran: 0.8 to 0.94). Our antimicrobial use monitoring system reduced the use of CP antibiotics and helped to restore the susceptibility of P. aeruginosa.
