Abstract
Objectives Delirium is an important prognostic factor in postoperative patients undergoing cardiovascular surgery and intervention, including transcatheter aortic valve implantation (TAVI). However, delirium after transcatheter aortic valve implantation (DAT) is difficult to predict and its pathophysiology is still unclear. We aimed to investigate whether preoperative cerebral blood flow (CBF) is associated with DAT and, if so, whether CBF measurement is useful for predicting DAT. Methods We evaluated CBF in 50 consecutive patients before TAVI (84.7±4.5 yrs., 36 females) using 99mTc ethyl cysteinate dimer single-photon emission computed tomography. Preoperative CBF of the DAT group (N = 12) was compared with that of the non-DAT group (N = 38) using whole brain voxel-wise analysis with SPM12 and region of interest-based analysis with the easy-Z score imaging system. Multivariable logistic regression analysis with the presence of DAT was used to create its prediction model. Results The whole brain analysis showed that preoperative CBF in the insula was lower in the DAT than in the non-DAT group (P<0.05, family-wise error correction). Decrease extent ratio in the insula of the DAT group (17.6±11.5%) was also greater relative to that of the non-DAT group (7.0±11.3%) in the region of interest-based analysis (P = 0.007). A model that included preoperative CBF in the insula and conventional indicators (frailty index, short physical performance battery and mini-mental state examination) showed the best predictive power for DAT (AUC 0.882). Conclusions These results suggest that preoperative CBF in the insula is associated with DAT and may be useful for its prediction.

Abstract
Abstract
Background
Cognitive impairment and depression are commonly noted in elderly frail patients with severe aortic stenosis (AS). However, their mechanisms and reversibility after treatment remain remain to be examined.
Purpose
In this study, we examined whether transcatheter aortic valve implantation (TAVI) increases cerebral blood flow (CBF) in cognitive/emotional brain areas, such as the hippocampus, in the elderly patients with severe AS.
Methods
We examined consecutive 15 right-handed patients with severe AS who were eligible for TAVI (median age 83.2 years, 12 (80%) women). We evaluated the following assessments both at baseline and 3 months after TAVI. Frailty was evaluated based on Fried scale, which consists of 5 items, including gait speed, cognitive function, weight loss, exhaustion, and inactivity. Frail and pre-frail were defined as greater than 3 and 1∼2 in the scale, respectively. Cognitive and emotional status were evaluated with Logical Memory (LM) II, Mini Mental State Examination (MMSE), and geriatric depression scale (GDS). Lower LM II (less than 4 points) and MMSE (less than 24 points) and higher GDS (more than 6 points) indicate worse memory, general cognitive function, and depressive symptoms, respectively. CBF images were recorded with 99mTc single-photon emission computed tomography and were analyzed using SPM12. Briefly, CBF images were firstly normalized to the standard Montreal Neurological Institute space. Then, a voxel-wise parametric analysis was conducted between normalized CBF images at baseline and those after TAVI (P<0.005 at each voxel). Continuous variables were presented as mean ± standard error (SE). Normality was assessed using the Shapiro-Wilk test. Continuous variables were compared with the use of paired t test. Linear mixed-model analysis was performed to evaluate changes in neuropsychological tests and CBF over time.
Results
In the present study, all patients were not robust but pre-frail (47.3%) or frail (53.7%). LM II score was significantly improved at 3 months after TAVI compared with baseline (baseline, 8.7 vs. 3 months, 13.8, P<0.01) (Figure A), whereas no significant changes in MMSE or GDS scores were noted (baseline, 24.6 vs. 3 months, 25.2 for MMSE; baseline, 4.3 vs. 3 months, 4.2 for GDS). Importantly, although no patients showed clinical symptoms or signs for transient ischemic attack or stroke after TAVI, CBF in the local regions, including the right hippocampus, was significantly increased after TAVI compared with baseline (P<0.005 at each voxel) (green arrowheads) (Figure B). Furthermore, CBF in the right hippocampus were positively correlated with LM II scores (P=0.017) (Figure C).

Conclusions
These results provide the first evidence that TAVI improves cerebral perfusion (especially that in the hippocampus) and cognitive functions in elderly patients with severe AS.

Abstract
Abstract
We fabricated polymer blends of recycled-PC (PC) and recycled-PET (PET) using high-shear processing technology. We also assessed its structure, morphology, and physical properties. Results of DSC measurements show that Tg of PC and Tc of PET shifted to higher temperatures by kneading under high-shear conditions. Results show further that the Tm of PET shifted to a lower temperature. Moreover, compatibilization progressed. TEM observations show that the PET domain was not confirmed completely under the kneading condition of 1 000 min−1/10 s or more. Compatibilization progressed. Tensile test results show that the PET ratio of 30 wt% (1 000 min−1/10 s) has higher breaking strain than neat PC does. Chemical resistance test results obtained by good solvent of PC demonstrated that blending of PET makes PC elution difficult.

Abstract
BACKGROUND The present study was designed to evaluate the postoperative values such as body temperature (BT), white blood cells (WBC), P/F ratio and C-reactive protein (CRP) associated with propofol or sevoflurane in patients undergoing thoracic surgery with one-lung ventilation. METHODS We retrospectively reviewed outcomes of patients undergoing video-associated thoracic surgery of the esophagus (VATS-E) with propofol (group P, n = 71) or sevoflurane (group S, n = 34). Data were taken at 1 POD and 2 POD in ICU. In addition, data of WBC and CRP were taken just before the operation and on 5 POD. Statistical analyses used t-value and two-way ANOVA with statistic significance as P < 0.05. RESULTS There was no significant difference between the two groups and we could not find the correlation between anesthetics and each factor. CONCLUSIONS Propofol and sevoflurane had similar effect on BT, WBC, P/F ratio and CRP in patients undergoing thoracic surgery with one-lung ventilation.

Abstract
Left ventricular assist devices (LVAD) are a currently established destination and bridge therapy until cardiac transplantation; hence, this patient population continues to increase. Here, we present the first report of abdominal aortic cross-clamping (ACC) in a LVAD patient undergoing emergency aneurysm repair. Anticoagulation was continued pre-and intra-operatively to avoid pump thrombosis. The pumping function of the LVAD is highly dependent on both preload and afterload. In this case, abdominal ACC, which increases the afterload, did not significantly influence circulatory dynamics. However, when the abdominal ACC was released, mean atrial pressure (MAP) fell to 42 mmHg, because preload reduction due to massive bleeding (3532 g) secondary to anticoagulation and afterload reduction by abdominal ACC release combined to cause critical hypotension. Maintenance of MAP required rapid infusion and use of an alpha-adrenergic agent. Surgical and anesthesia times were 411 and 525 min, respectively. Total blood loss was 5389 g, respectively. The patient was discharged after 25 postoperative days with no major complications. ACC release, with its accompanying decrease in preload and afterload, and massive bleeding due to anticoagulation in these patients require careful management.

Abstract
BACKGROUND The number of lung transplantation has tended to increase as a treatment for patients with pulmonary arterial hypertension (PAH) and lymphangiomyomatosis (LAM) in Japan. However, we have little evidence about the comparison of perioperative management in patients with PAH and that in patients with LAM. METHODS In this retrospective study, ten patients with PAH and seventeen patients with LAM who underwent the lung transplantations between 2006 and 2011 were enrolled. RESULTS PAH patients received double lung transplantation with intraoperative cardiopulmonary bypass (CPB) support. Before anesthesia induction, percutaneous cardiopulmonary support (PCPS) was begun. Most of LAM patients received single lung transplantation without using CPB support and PCPS support before anesthesia induction. But sometimes during an operation PCPS support was necessary. Postoperative PCPS support showed no significant differences between PAH and LAM. The four year survival rate was 80% (PAH) and 87.8% (LAM). Pao2/FIo2 in patients with PAH and in those with LAM, %FEV10 in those with LAM after surgery improved when compared to those before surgery. CONCLUSIONS The large difference in perioperative management between patients with PAH and those with LAM is an important knowledge for anesthesist.

Abstract
BACKGROUND The number of lung transplantation has tended to increase as a treatment for patients with pulmonary lymphangioleiomyomatosis (LAM) in Japan. However, we have little evidence about the correlation between preoperative medical parameters and intraoperative complications. METHODS A retrospective study was performed in 17 patients with LAM undergoing the lung transplantations between 2006 and 2011. RESULTS Major intraoperative complications were as follows: hypotension, pulmonary hypertension, hypoxemia and blood loss of more than 1,000 ml. According to the medical records, no patients was diagnosed pulmonary hypertension before surgery and no preoperative parameters predicted intraoperative pulmonary hypertension. Therefore, according to the medical records it seemed difficult to predict the risk of the intraoperative pulmonary hypertension and hypotension. Intraoperative hypoxemia and the requirements of percutaneous cardiopulmonary support (PCPS) are not associated with preoperative PaO2 and %FEV1.0. Pleurodesis and the use of PCPS were significantly correlated with an increased risk of intraoperative massive bleeding. The four year survival rate was 87.8%. %FEV1.0, PaO2/FI(O) and %DL(CO) after surgery improved when compared to those before surgery. CONCLUSIONS Although the intraoperative complications such as hypotension, pulmonary hypertension, hypoxemia and/or massive bleeding frequently occurred in patients with LAM during the lung transplantations, it was difficult to predict them except the massive bleeding of more than 1,000 ml before surgery. However, lung transplantation is a valuable therapy for patients with end-stage LAM.

Abstract
Primary pulmonary hypertension is a fatal disease that frequently becomes evident in pregnancy. The management of pregnant women with primary pulmonary hypertension poses a number of difficult problems, especially where regional anesthesia is considered to be contraindicated. A 30-year-old woman who developed primary pulmonary hypertension at 23 weeks of pregnancy was transferred to our hospital. Systolic pulmonary artery pressure and plasma brain natriuretic peptide levels were markedly elevated. Nitric oxide inhalation and prostacyclin prevented the progression of cardiac failure and reduced both plasma brain natriuretic peptide and pulmonary artery pressure. Cesarean section was performed at 32 weeks under general anesthesia. A combination of nitric oxide, prostacyclin, nitroglycerin, and dobutamine were administered during surgery. Intravenous dexmedetomidine was specifically used during emergence and recovery from anesthesia. This provided effective pain relief and hemodynamic stability. Throughout the clinical course, brain natriuretic peptide levels was monitored and used as an indicator of cardiac failure.

Abstract
The function of immune system is to protect hosts from invading microorganisms by destroying infected cells while minimizing damage to tissues. Among immune cells, CD4(+)CD25(+) regulatory T cells (Treg cells) control immune responses by limiting infectious processes. However, it remains unclear whether Treg cells are induced in systemic inflammatory response syndrome (SIRS) or infectious SIRS (i.e. sepsis). SIRS and sepsis are associated with stressful inflammatory conditions. We therefore measured CD25(+) T cells and circulating CD4(+) T cells, along with plasma levels of CD25, interleukin (IL)-6, and IL-10, in 20 septic patients (64 +/- 11 years), 16 SIRS patients (59 +/- 16 years), and control subjects: 13 elderly (60 +/- 16 years) and 14 young volunteers (28 +/- 3 years). Septic patients (23.3 +/- 11.8%, p < 0.01) showed significantly higher percentages of CD25(+) cells among CD4(+) T cells (i.e. Treg cells) than did either young (10.6 +/- 3.7%) or elderly volunteers (11.1 +/- 3.8%). The percentages of Treg cells in septic patients were higher than those in SIRS patients (12.4 +/- 6.9%, p < 0.01). Moreover, plasma levels of soluble CD25 were significantly higher in septic patients, compared to the levels in SIRS patients or volunteers (p < 0.01). No significant difference in plasma levels of IL-6 or IL-10 was found between septic patients and SIRS patients. Thus, sepsis is associated with the increased percentages of Treg cells and elevated plasma level of soluble CD25. The elevation of these parameters might be a useful marker of infections in SIRS.

Abstract
A simultaneous determination method of quaternary amino steroidal muscle relaxants, pancuronium (PAN), vecuronium (VEC), and 17-monodesacetyl pancuronium (17-OH-PAN), 3,17-bisdesacetyl pancuronium (3,17-OH-PAN), 3-monodesacetyl vecuronium (3-OH-VEC), 3,17-bisdesacetyl vecuronium (3,17-OH-VEC) in human serum was developed using liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS). The weak cation exchange cartridge was useful for the extraction of these compounds. Under optimized LC-ESI-MS conditions, these compounds were almost fully separated within 6.5 min. Linear responses over the concentration range 0.25-50.0 ng/mL were demonstrated for each compound. The developed method successfully detected VEC, 3-OH-VEC and 3,17-OH-VEC in serum intravenously administered with VEC. The level of 3-OH-VEC was higher than other compounds. This suggested that 3-OH-VEC was useful as a forensic probe in VEC administration.

Abstract
In the intubated patient, the presence of an endotracheal tube increases the work of breathing during spontaneous breathing. The tube compensation technique was developed as a new ventilator mode that can compensate for that additional the work of breathing. We investigated the respiratory parameters during the pressure support ventilation 0, 5, 10 cmH2O and tube compensation 100% modes of the Puritan Bennett 840 ventilator in ten postoperative patients who had undergone radical surgery for oesophageal cancer. Measurements were performed just before extubation. The tidal volume, respiratory rate and other respiratory parameters were measured with a Ventrak respiratory monitor, and the duty ratio, mean inspiratory flow, and rapid shallow breathing index were calculated. In particular, we performed a comparison between pressure support ventilation 5 cmH2O and tube compensation 100%, because pressure support ventilation 5 cmH2O is the usual ventilating mode before the extubation in our intensive care unit. The tidal volume of pressure support ventilation 10 cmH2O was significantly larger and the respiratory rate was significantly lower than the other three modes. There was no significant difference in the minute volume, tidal volume, and respiratory rate between pressure support ventilation 5 cmH2O and tube compensation 100%. The duty ratio of pressure support ventilation 10 cmH2O was significantly smaller than the other three modes. There was no significant difference in the duty ratio and rapid shallow breathing index between pressure support ventilation 5 cmH2O and tube compensation 100%. It was concluded that the assist levels of pressure support ventilation 5 cmH2O and tube compensation 100% were almost equal for clinical purposes.

Abstract
In Japan, most couples use traditional methods, with about 80% relying on the condom and a further significant proportion on the rhythm method. In fact a combination of both methods is common among married couples. The oral contraceptives have the following advantages: Reversibility, simple and easy to use, coitally independent, no skill or knowledge required for its use, high acceptability, no pain or discomfort at use, self-administration, while they have the following disadvantages: Inadequate during lactation, sustained motivation in the female side required, clinical contraindication exists, possible side-effects such as nausea, vomiting, breast tenderness, weight gain, questionable possibility of serious side effects such as hypertension, thromboembolic diseases etc., medical supervision and follow up required, expensive cost. The use of the steroidal preparations for contraceptive purpose in Japan awaits official approval. Under present regulations, it is not illegal for the physicians to prescribe the pill, and currently six preparations are available and all contain 50 microgram of estrogen. The reduction in the estrogen and progestogen content of the pill did not appreciably compromise contraceptive potential while untoward effects were considerably lowered. The development and use of the new progestogen also contributed to minimize the possible side effects. Efforts are now being directed at a pill which minimizes metabolic change, decreases the incidence of breakthrough bleeding or spotting, without compromising efficacy. It is with these goals in mind that the multi-phasic pills have been developed in the belief that many of the undesirable side-effects can be circumvented while maintaining almost 100% conception control.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Two siblings with succinic acidemia, a hitherto unreported organic acidemia, were investigated. Succinic acidemia, lactic acidosis and respiratory distress were observed in one of the siblings, who died 37 days after birth, and succinic acidemia was also detected in the next sibling at the fetal stage. NADH-cytochrome c reductase activity was significantly low in both cases and NADH-ferricyanide reductase activity was also low in the fetal case, suggesting a complex I deficiency of the electron transport system in the mitochondrial membrane.

Abstract
Bestrabucil, the benzoate of an estradiol-chlorambucil conjugate, was initially developed as a target-oriented anticancer agent for breast cancers with positive estrogen receptors, by conjugating a tumoricidal agent, chlorambucil, to a vehicle, estradiol. Further studies, however, revealed that regardless of the presence of estrogen receptors, bestrabucil selectively accumulates in malignant tumor cells. The unique feature of bestrabucil, selective affinity to tumor cells, was demonstrated in in vitro and in vivo studies. Significantly larger amounts of 3H-bestrabucil accumulated in malignant cells (3T3-SV40 transformed) than in normal cells (3T3). In vitro inhibition effects of bestrabucil on cell growth was observed only in malignant cells. Selective accumulation of bestrabucil in malignant tumor tissues was also demonstrated in in vivo experiments. After a single oral administration of 100 mg/kg of bestrabucil to female Wistar rats bearing Walker 256 carcinoma, bestrabucil accumulated significantly occurred in tumor tissues with little or no accumulation in normal tissues and blood. Anti-tumor effects and toxicities of bestrabucil and chlorambucil, were compared using Walker 256 carcinoma. Bestrabucil exerted its antitumor effects with little change in leucocyte counts in the peripheral blood, whereas chlorambucil showed significant side effects. Finally, selective accumulation of bestrabucil in malignant tumor tissues, was demonstrated clinically. Tumor specimens obtained during the operation of patients with various types of cancer, 24 hours after oral administration of 100 mg of bestrabucil, contained significantly larger amounts of bestrabucil compared with adjacent normal tissues. Clinical trials of bestrabucil are being carried out at present. Bestrabucil seems to be a promising target-oriented anticancer agent and deserves further investigation.

Abstract
The authors studied antipyrine disposition before and after delivery in 4 epileptic women whose anticonvulsant plasma level per dosage ratio was lowered during pregnancy, and compared the results to those found in nonpregnant women undergoing antiepileptic treatment (N = 6) and healthy women (N = 6). The antipyrine clearance at term (0.53 +/- 0.11 ml/min/kg, mean +/- SD) was lower than it was early during puerperium (0.70 +/- 0.14 ml/min/kg, P less than .05) and approximately 3 months after delivery (1.14 +/- 0.26 ml/min/kg, P less than .01). The antipyrine clearance in nonpregnant epileptics (1.17 +/- 0.44 ml/min/kg) was comparable to that found 3 months after delivery, whereas it was significantly (P less than .01) higher than that found in healthy women (0.47 +/- 0.02 ml/min/kg). These observations suggest that the fall during pregnancy of anticonvulsant plasma concentrations relative to dosage is not attributable to the enhanced oxidative process of hepatic drug metabolism.

Abstract
The study group was organized to evaluate the usefulness of cefmenoxime (CMX) injection, a new synthetic cephalosporin, for the treatment of infections in the field of obstetrics and gynecology. Fundamental and clinical studies were made by the society and the following results were obtained. 1. The peak distribution of CMX's MIC for E. coli, Klebsiella sp., Enterobacter sp., Bacteroides sp. and Peptococcus sp. isolated from obstetrical and gynecological infections with relatively high frequencies area 0.1, less than or equal to 0.05, 0.2, 3.13, 1.56 micrograms/ml, respectively, with an inoculation of 10(6) cells/ml. 2. When 1 g of CMX is administered by intravenous drip infusion for 1 hour, the maximum concentrations in various tissues of female genital organs were as follows: 14.2 and 13.2 micrograms/g in ovary and oviduct, respectively, at 1.20 hours after the start of administration, and 16.9 and 26.3 micrograms/g in corpus uteri and cervix uteri, respectively, after 1 hour. As for the transfer to the exudate in the pelvic dead cavity, the peak concentration was 15.6 micrograms/ml after 2.13 hours. 3. In the clinical studies, CMX was given to 258 cases with female genital organ infections and others. As for the clinical effects, with exclusion of 3 cases in which other antibiotics are concomitantly used, responses were excellent in 76 cases, good in 162 cases and poor in 17 cases, among 255 cases in total. The efficacy rate was 93.3%. The efficacy rates by diseases were 97.1% (68/70) for intrauterine infections, 88.8% (79/89) for intrapelvic infections, 98.4% (62/63) for adnexitis, and 100% (23/23) for infections of external genital organs. As for the clinical effects on causative bacteria, the efficacy rates were 100% (19/19) for single infections due to Gram-positive bacteria, 94.8% (55/58) for single infections due to Gram-negative bacteria, and 88.2% (15/17) for single infections due to anaerobic bacteria. And its efficacy rates were 89.6% (69/77) for mixed infection cases. Side effects were observed in 2 cases (0.8%); 1 case with eruption, and 1 case with diarrhea and vomiting. As for abnormal laboratory findings, lower white blood cell count was observed in 2 cases and elevation of the values regarding hepatic functions in 9 cases. All cases were returned to the normal after the completion of the administration. Cefmenoxime showed a satisfactory clinical efficacy and a potent bacteriological effect in treatment of the infections in the field of obstetrics and gynecology, and it has been concluded that cefmenoxime will be useful addition to the antibiotics for the therapy of these infections.

Abstract
A soluble membrane extract was prepared by a hypotonic extraction method from a cultured cell line, CKS, derived from serous cystadenocarcinoma of the ovary. The leukocyte migration inhibition assay in agar was used to determine the cell-mediated immune response with this extract in patients with ovarian carcinoma in comparison with patients with other benign or malignant tumors and normal healthy subjects. With 100 micrograms protein/ml of the extract, leukocytes from 15/25 patients with ovarian carcinoma showed positive response, whereas 5/30 patients with benign tumors, 2/23 patients with non-ovarian carcinomas, and 0/13 normal healthy controls did so. These findings suggested that the soluble membrane extract from the CKS cells specifically inhibited migration of leukocytes from patients with ovarian carcinoma. There was a tendency that the stage III or IV patients responded to the extract more frequently than the stage I patients irrespective of histological type of ovarian carcinoma. The migration inhibition assay with a basic encephalitogenic protein (100 micrograms protein/ml) from bovine brain was performed simultaneously with the ovarian cancer extract. One of 20 patients with ovarian carcinoma, 1/29 patients with benign tumors, 1/22 patients with non-ovarian carcinomas, and 0/13 normal healthy controls responded positively. Therefore, cross-reactivity between the basic protein and tumor-associated antigens could not be demonstrated in the present study.

Abstract
A new synthesized Prostaglandin E1 analogue, 16,16-dimethyl-trans-delta 2-Prostaglandin E1 methyl ester, has been shown to be effective in termination of 1st and second trimester pregnancy following vaginal administration. Suppositories, each containing 1 mg Prostaglandin E1 derivative, were administered five times to each of fifty pregnant women of five to twenty gestational weeks at three-hourly intervals. The procedure was clinically effective in 86% of the patients resulting in 56% complete and 30% incomplete abortions. The cervix of all patients was dilated up to 7 mm in diameter at the second insertion of the suppository. Vaginal bleeding and lower abdominal pain not requiring sedation were observed in all patients. Diarrhea (42%), vomiting (6%), and fever (4%) were the most common side effects. The Karyopyknotic Index of the vaginal smear increased significantly (p less than 0.01) twelve hours after the initial insertion. The superficial cells of the cervix gradually degenerated during the termination procedure.
