Abstract
Background The aim of this study was to compare the short-term outcomes of the duodenum-first multidirectional approach (DMA) in laparoscopic right colectomy with those of the conventional medial approach to assess its safety and feasibility. Methods This retrospective study enrolled 120 patients who had laparoscopic surgery for right-sided colon cancer in our institution between April 2013 and December 2019. Fifty-four patients underwent colectomy using the multidirectional approach; among these, 20 underwent the DMA and 34 underwent the caudal-first multidirectional approach (CMA). Sixty-six patients underwent the conventional medial approach. Complications within 30 days of surgery were compared between the groups. Results There were 54 patients in the multidirectional group [29 females, median age 72 years (range 36–91 years)] and 66 in the medial group [42 females, median age 72 years (range 41–91 years)]. Total operative time was significantly shorter in multidirectional approach patients than conventional medial approach patients (208 min vs. 271 min; p = 0.01) and significantly shorter in patients who underwent the DMA compared to the CMA (201 min vs. 269 min; p < 0.001). Operative time for the mobilization procedure was also significantly shorter in patients who underwent the DMA (131 min vs. 181 min; p < 0.001). Blood loss and incidence of postoperative complications did not differ. In 77 patients with advanced T3/T4 tumors, the DMA, CMA, and conventional medial approach were performed in 13, 21, and 43 patients, respectively. Total operative time and operative time of the mobilization procedure were significantly shorter in patients undergoing DMA. Blood loss and incidence of postoperative complications did not differ. R0 resection was achieved in all patients with advanced tumors. Conclusions The DMA in laparoscopic right colectomy is safe and feasible and can achieve R0 resection with a shorter operative time than the conventional medial approach, even in patients with advanced tumors.

Abstract
PURPOSE To investigate optimal risk factors, including atrophy of the abdominal rectus muscle (ARM) for postoperative parastomal hernia (PH) in patients who underwent end colostomy at left lower quadrant. METHODS This single-institution retrospective study included 91 patients who underwent end colostomy between April 2004 and December 2015. The surgical and long-term outcomes among patients with or without PH were collected and compared. RESULTS Altogether, 22 (24.2%) patients had a PH including 15 (68.2%) patients with a simultaneous incisional hernia. Univariate analysis showed that older patients (71 ± 11.9 vs. 64 ± 12.2 years, p = 0.03) and those with higher body mass index (BMI) (23.8 ± 3.8 vs. 20.9 ± 3.3 kg/m2, p < 0.001) had a statistically significant relation with having PHs. Relative atrophy of left abdominal rectus muscle was more frequently found in patients with PH (ratio of left side/right side; caudal level and medial side: 0.66 vs. 0.92, p < 0.01, caudal level and lateral side: 0.95 vs. 1.03, p = 0.04). Multivariate analysis revealed that BMI > 25 kg/m2 [odds ratio (OR) 9.05, 95% confidence interval (CI) 2.06-39.76, p = 0.003] and atrophy of the left lower medial portion of the abdominal rectus muscle (OR 12.85, 95% CI 2.49-66.39, p = 0.002) were independent risk factors for PHs. Neither the laparoscopic approach nor the extraperitoneal route of the colostomy was proven to correlate with a lower rate of PHs. CONCLUSIONS High BMI and atrophic change of ARM were significantly associated with PH development. Surgical techniques for prevention of atrophic change of ARM are expected to reduce the incidence of PHs.

Abstract
Species-specific restriction fragment length polymorphism in the intron of the androgen receptor gene (ar5) was found in glass to silver-stage individuals of Anguilla japonica (n = 51) and A. marmorata (n = 21). The sequence analysis of 16S rDNA from 328 anguillid leptocephali collected in the North Equatorial Current of the western North Pacific Ocean revealed the specimens to be A. japonica (n = 194), A. marmorata (n = 128), A. bicolor pacifica (n = 5) and A. luzonensis (n = 1). All leptocephali of A. japonica and A. marmorata were monomorphic and did not share an allele at the ar5 locus, indicating that the two species are reproductively isolated.

Abstract
Purpose Cultural differences are hypothesized to influence patients’ Quality of Life (QoL) reports. However, there is a lack of empirical cross-cultural studies comparing QoL of patients with cancer. This study aims to compare QoL of women with breast cancer in the Netherlands and Japan, and to investigate the association of QoL with sociodemographic, clinical, and psychological variables (illness perceptions). Methods Dutch (n = 116) and Japanese (n = 148) women with early breast cancer undergoing chemotherapy completed the EORTC QLQ-C30 and Brief Illness Perception Questionnaire immediately before their second cycle of chemotherapy. Results Dutch women reported poorer Physical, Role, Emotional, and Cognitive functioning than Japanese women. Additionally, illness perceptions were significantly different in Japan and the Netherlands, but these did not vary across treatment type. In Japan, QoL of women receiving AC-chemotherapy was better than that of women receiving FEC-chemotherapy, whereas in the Netherlands, QoL did not vary as a function of chemotherapy. Illness perceptions about symptom severity, adverse consequences, and emotional representations were negatively related to most domains of patients’ QoL in both countries. Adding illness perceptions as covariates to the ANOVA analyses rendered the effects of country and treatment type on QoL non-significant. Conclusions Comparing Dutch and Japanese women with early breast cancer revealed important differences in treatment modalities and illness perceptions which both appear to influence QoL. Perceptions about cancer have been found to vary across cultures, and our study suggests that these perceptions should be considered when performing cross-cultural studies focusing on patient-reported outcomes.

Abstract
The aim of this study was to evaluate the barrier function of platelet-induced epithelial sheets on titanium surfaces. The lack of functional peri-implant epithelial sealing with basal lamina (BL) attachment at the interface of the implant and the adjacent epithelium allows for bacterial invasion, which may lead to peri-implantitis. Although various approaches have been reported to combat bacterial infection by surface modifications to titanium, none of these have been successful in a clinical application. In our previous study, surface modification with protease-activated receptor 4–activating peptide (PAR4-AP), which induced platelet activation and aggregation, was successful in demonstrating epithelial attachment via BL and epithelial sheet formation on the titanium surface. We hypothesized that the platelet-induced epithelial sheet on PAR4-AP–modified titanium surfaces would reduce bacterial attachment, penetration, and invasion. Titanium surface was modified with PAR4-AP and incubated with platelet-rich plasma (PRP). The aggregated platelets released collagen IV, a critical BL component, onto the PAR4-AP–modified titanium surface. Then, human gingival epithelial cells were seeded on the modified titanium surface and formed epithelial sheets. Green fluorescent protein (GFP)–expressing Escherichia coli was cultured onto PAR4-AP–modified titanium with and without epithelial sheet formation. While Escherichia coli accumulated densely onto the PAR4-AP titanium lacking epithelial sheet, few Escherichia coli were observed on the epithelial sheet on the PAR4-AP surface. No bacterial invasion into the interface of the epithelial sheet and the titanium surface was observed. These in vitro results indicate the efficacy of a platelet-induced epithelial barrier that functions to prevent bacterial attachment, penetration, and invasion on PAR4-AP–modified titanium.

Abstract
This study evaluated the indications, surgical techniques, and outcomes of allograft pancreatectomy based on a single center experience. Between 2003 and 2013, 47 patients developed pancreas allograft failure, excluding mortality with a functioning pancreas allograft. Early graft loss (within 14 days) occurred in 16, and late graft loss in 31. All patients with early graft loss eventually required allograft pancreatectomy. Nineteen of 31 patients (61%) with late graft loss underwent allograft pancreatectomy. The main indication for early allograft pancreatectomy included vascular thrombosis with or without severe pancreatitis, whereas one recipient required urgent allograft pancreatectomy for gastrointestinal hemorrhage secondary to an arterioenteric fistula. In cases of late allograft pancreatectomy, graft failure with clinical symptoms such as abdominal discomfort, pain, and nausea were the main indications (13/19 [68%]), simultaneous retransplantation without clinical symptoms in 3 (16%), and vascular catastrophes including pseudoaneurysm and enteric arterial fistula in 3 (16%). Postoperative morbidity included one case each of pulmonary embolism leading to mortality, formation of pseudoaneurysm requiring placement of covered stent, and postoperative bleeding requiring relaparotomy eventually leading to femoro-femoral bypass surgery 2 years after allograftectomy. Allograft pancreatectomy can be performed safely, does not preclude subsequent retransplantation, and may be lifesaving in certain instances.

Abstract
We investigated the disease-free survival (DFS) of HER2-positive primary breast cancer patients treated with neoadjuvant chemotherapy plus trastuzumab, as well as predictive factors for DFS and pathologic response. Data from 829 female patients treated between 2001 and 2010 were collected from 38 institutions in Japan. Predictive factors were evaluated using multivariate analyses. The 3-year DFS rate was 87 % [95 % confidence interval (CI) 85-90]. The pathologic complete response (pCR: ypT0/is + ypN0) rate was 51 %. The pCR rate was higher in the ER/PgR-negative patients than in the ER/PgR-positive patients (64 vs. 36 %, P < 0.001). Patients with pCR showed a higher DFS rate than patients without pCR (93 vs. 82 %, P < 0.001). Multivariate analysis revealed three independent predictors for poorer DFS: advanced nodal stage [hazard ratio (HR) 2.63, 95 % CI 1.36-5.21, P = 0.004 for cN2-3 vs. cN0], histological/nuclear grade 3 (HR 1.81, 95 % CI 1.15-2.91, P = 0.011), and non-pCR (HR 1.98, 95 % CI 1.22-3.24, P = 0.005). In the ER/PgR-negative dataset, non-pCR (HR 2.63, 95 % CI 1.43-4.90, P = 0.002) and clinical tumor stage (HR 2.20, 95 % CI 1.16-4.20, P = 0.017 for cT3-4 vs. cT1-2) were independent predictors for DFS, and in the ER/PgR-positive dataset, histological grade of 3 (HR 3.09, 95 % CI 1.48-6.62, P = 0.003), clinical nodal stage (HR 4.26, 95 % CI 1.53-13.14, P = 0.005 for cN2-3 vs. cN0), and young age (HR 2.40, 95 % CI 1.12-4.94, P = 0.026 for ≤40 vs. >40) were negative predictors for DFS. Strict pCR (ypT0 + ypN0) was an independent predictor for DFS in both the ER/PgR-negative and -positive datasets (HR 2.66, 95 % CI 1.31-5.97, P = 0.006 and HR 3.86, 95 % CI 1.13-24.21, P = 0.029, respectively). These results may help assure a more accurate prognosis and personalized treatment for HER2-positive breast cancer patients.

Abstract
Abstract
BACKGROUND:
Addition of trastuzumab to neoadjuvant chemotherapy (NAC) improved pathologic complete response (pCR) rate in HER2-positive breast cancer. Although recent trials have shown favorable prognosis with NAC plus trastuzumab, clinicopathological factors to predict the outcome have not been fully understood. The aim of this study was to investigate the survival after NAC with trastuzumab and to explore the predictive factors.
PATIENTS AND METHODS:
This is a multicenter retrospective observational study. Patients with HER2-positive primary breast cancer treated with NAC plus trastuzumab from 2001 to 2010 were identified from the institutional database. Primary end point was disease-free survival (DFS). pCR was defined as ypT0/is+ypN0. Kaplan-Meier method was used to estimate DFS. Logistic regression and proportional hazard analysis were used to identify clinicopathological factors to predict pCR and DFS, respectively.
RESULTS:
733 patients were included in the analysis (whole dataset). 425 were ER/PgR-negative (HR- dataset) and 306 were ER/PgR-positive (HR+ dataset). Radiation therapy was performed in 90% of lumpectomy and 31% of mastectomy. Hormonal therapy was performed in 84% of HR+ dataset. pCR rate was 45% in whole dataset, 60% in HR- dataset, and 34% in HR+ dataset. Table 1 showed the result of multivariate analysis for pCR in whole dataset. When HR+ and HR- dataset were analyzed separately, no definitive predictors for pCR were identified in multivariate analysis. Although the patients with pCR showed a significantly favorable prognosis than those without pCR at 3 years DFS, in whole dataset (93% vs 83%, p<0.0001) and HR- dataset (94% vs 80%, p<0.0001), there was no significant difference in HR+ dataset (89% vs 86%, p = 0.10). Different predictors were selected for DFS when multivariate analysis was conducted separately between HR- and HR+ dataset (Table 2).
CONCLUSIONS:
In this observational study, we clarified predictors for pCR and DFS in HER2-positive patients treated with neoadjuvant trastuzumab containing therapy based on tumor subtype. Our results may help us to predict the prognosis more precisely and to simulate the disease course.

Abstract
Abstract
Background: Neoadjuvant chemotherapy (NAC) with taxane and FEC concurrently with trastuzumab is a potent regimen in women with HER2-positive breast cancer (BC), and several studies revealed high pCR rates in BC patients treated with this regimen. In the present study, we compared the status of biomarkers before and after NAC, and evaluated rates and patterns of discordant biomarker expression. We also evaluated differences of prognosis between patients with discordant biomarker expression and those with concordant expression.
Patients and Methods: We investigated 118 Japanese women with invasive HER2 positive BC. Patients received 12 cycles of paclitaxel or 4 cycles of docetaxel followed by 4 cycles of FEC-75 with concomitant trastuzumab for 24 weeks and were followed for ≥1 year after surgery. Of these, 27 patients with residual tumors 5 mm or larger were analyzed. HER2, ER, PgR, and Ki67 were examined in primary and residual tumors. Furthermore, recurrence-free survival (RFS) and overall survival (OS) were analyzed between patients classified based on these biomarkers.
Results: Patients with pCR after NAC (75/118; 63.5%) had significantly better RFS than non-pCR patients (median follow-up: 41 months). Residual tumors were obtained from 27 of 43 non-pCR patients and examined for immunohistochemical biomarker expression. In 14/27 non-pCR patients (51.9%), residual tumors were HER2 negative, despite being HER2 positive before NAC: HER2 score changed from 3+ to 0 or 1+ in 8/18 patients (44.4%) and from 2+ to 0 or 1+ in 6/9 (66.7%). ER expression changed in 2 patients (1 positive to negative and 1 negative to positive). Patterns of biomarker expression in residual tumors were HER2 (+)/ER (–), 6 patients (22.2%); HER2 (+)/ER (+), 7 (25.9%); HER2 (–)/ER (+), 11 (40.7%); and triple negative (TN), 3 (11.1%). Recurrence was observed in 8/27 (29.6%) non-pCR patients, and patterns of biomarker expression in residual tumors were HER2 (+)/ER (–), 3 patients; HER2 (+)/ER (+), 2; and HER2 (–)/ER (+), 3. In addition, 1 patient with a HER2 (+)/ER (+) tumor and 1 patient with a HER2 (−)/ER (+) tumor died. RFS and OS were not statistically different between patients classified based on ER and Ki67 expressions. However, in the 18 non-pCR patients with primary tumor HER2 score of 3+ (overexpression of HER2 protein), the 10 with HER2-positive residual tumors showed significantly lower RFS than the 8 with HER2-negative (p < 0.04).
Conclusions: Although this regimen achieved a high pCR rate in HER2-positive BC patients, about 40% still had residual tumors. In the present study, we found that positive HER2 expression seen in pre-NAC tumors became negative in 52% of residual tumors after NAC. Theses HER2-negative residual tumors might not respond well to trastuzumab therapy, and residual tumors remaining HER2 positive might show low or no response to trastuzumab therapy. Moreover, the prognosis seems worse for non-pCR patients with HER2-positive residual tumors. However, Ki67 was not a significant prognostic factor. Examining biomarker expression of residual tumors after NAC seems very important for deciding further adjuvant therapy.

Abstract
CD40 plays a critical role in adaptive immunity, and alveolar macrophages in patients with sarcoidosis express higher levels of CD40. This study investigated the association of rs1883832, a functional single-nucleotide polymorphism in the CD40 gene with susceptibility to sarcoidosis and phenotypes of sarcoidosis. Genotyping of rs1883832 in 175 Japanese patients with sarcoidosis and 150 age- and sex-matched controls revealed no significant difference between the genotypes of the patient and control groups (CC/CT/TT, 32.8/52.0/14.7% in the patients; 37.3/48.0/14.7% in the controls, P = 0.66; allele C, 59.1% in the patients, 61.3% in the controls, P = 0.57). T-cell and CD4+ cell counts in the bronchoalveolar lavage fluid were significantly higher in the TT genotype group than in the CC and CT genotype group.

Abstract
The clinical outcome of sarcoidosis is quite variable. Several scoring systems have been used to assess the level of disease and clinical outcome. The definition of clinical phenotypes has become an important goal as genetic studies have identified distinct genotypes associated with different clinical phenotypes. In addition, treatment strategies have been developed for patients with resolving versus non resolving disease. A task force was established by the World Association of Sarcoidosis and Other Granulomatous diseases (WASOG) to define clinical phenotypes of the disease based on the clinical outcome status (COS). The committee chose to examine patients five years after diagnosis to determine the COS. Several features of the disease were incorporated into the final nine categories of the disease. These included the current or past need for systemic therapy, the resolution of the disease, and current status of the condition. Sarcoidosis patients who were African American or older were likely to have a higher COS, indicating more chronic disease. The COS may be useful in future studies of sarcoidosis.

Abstract
A 90° sector type spin rotator was developed for measurement of the z-direction component of a spin polarization, which is parallel to the emitter axis. The rotator enables us to measure all components of electron spins field-emitted from a single crystalline magnetite. In-plane component of spin polarization dominated of field-emitted electrons from single crystalline magnetite whisker, thus it is suggested that the magnetization of the magnetite whisker results from the anisotropy of crystalline structure rather than its shape.

Abstract
346 Background: There is no established treatment strategy for unresectable pancreatic cancer, and the prognostic effect of intraoperative radiotherapy (IORT) is considered to be limited. Methods: We reviewed 614 surgical cases of pancreatic cancer and selected 198 cases that did not undergo pancreatectomy because of distant metastasis or locally advanced disease, at the Department of Surgery II, between July 1981 and June 2009. Liver metastasis was observed in 70 patients and peritoneal metastasis in 44. Treatment for those who were feasible consisted of IORT and/or postoperative chemotherapy. Overall survival and prognostic factors were evaluated for all patients and for each pattern of disease spread. Results: IORT was performed in 120 patients (61%), and chemotherapy was indicated in 80 (40%). Overall survival in the non-treatment group was significantly inferior to that for IORT alone and IORT plus gemcitabine (GEM)-based chemotherapy (median survival time: 3.2 months vs. 6.1 and 7.9 months; P = 0.0001 and <0.0001, respectively). After multivariate analysis, IORT and GEM-based chemotherapy were identified as independent prognostic factors [hazard ratio (HR) = 0.51, P < 0.001; HR = 0.43, P < 0.001]. IORT was an independent prognostic determinant for patients with peritoneal metastasis (HR = 0.24, P = 0.011), whereas it was not for those with liver metastasis (HR = 0.78, P = 0.381). Conclusions: The prognostic value of IORT is most prominent in the peritoneal disease. IORT followed by GEM-based chemotherapy is possibly one of the most recommended treatment strategies in unresectable pancreatic cancer. No significant financial relationships to disclose.

Abstract
BACKGROUND Nutritional status plays an important role in the incidence of postoperative complications and the prognosis of various tumours. The prognostic value of preoperative nutritional factors in patients with pancreatic cancer is not known. METHODS This retrospective study included 268 patients who underwent resection for adenocarcinoma of the pancreas. The predictive value of preoperative nutritional status for postoperative outcome (survival, complications) was assessed. Nutritional factors included the three constitutional indices, serum albumin and Onodera's prognostic nutrition index (PNI), calculated as 10 × serum albumin (g/dl) + 0·005× total lymphocyte count (per mm(3)). RESULTS In multivariable analysis preoperative low PNI (but not low albumin) was an independent prognostic factor for poor survival: hazard ratio (HR) 1·73 (95 per cent confidence interval (c.i.) 1·21 to 2·47). The accuracy of a PNI value of less than 45 as cut-off for clinically significant preoperative malnutrition in predicting 1- or 2-year survival after surgery was, however, limited (66·4 and 56·3 per cent respectively). Low preoperative albumin concentration and PNI were significantly associated with postoperative complications: odds ratio 1·98 (95 per cent c.i. 1·18 to 3·32) and 2·14 (1·23 to 3·73) respectively. Low PNI and low body mass index were independently associated with pancreatic fistula: HR 2·52 (1·37 to 4·63) and 0·40 (0·17 to 0·93) respectively. CONCLUSION The PNI is associated with overall survival and postoperative complications, in particular pancreatic fistula, in patients with pancreatic cancer. The moderate accuracy of PNI as a predictor of survival limits its clinical use.

Abstract
BACKGROUND Cardiac involvement and pulmonary hypertension (PH) are life-threatening complications in sarcoidosis. OBJECTIVE This study aimed to investigate the utility of plasma NT-proBNP in the assessment of these conditions in sarcoidosis patients. STUDY DESIGN AND METHODS A prospective, observational study was performed on 150 consecutive Japanese sarcoidosis patients. Doppler echocardiography was performed in all subjects, and those who were successfully evaluated for PH status were included in the analysis. Cardiac sarcoidosis was diagnosed based on Japanese guidelines, and PH was defined as estimated systolic pulmonary artery pressure (sPAP) > or = 35 mmHg. The diagnostic accuracy of NT-proBNP according to the presence of cardiac sarcoidosis and PH was assessed based on receiver-operator characteristic (ROC) curves. RESULTS 130 subjects were successfully evaluated for PH status. Of these, 29 met the diagnostic criteria of cardiac sarcoidosis, and 21 were diagnosed with PH. Plasma NT-proBNP levels were significantly higher in patients with cardiac sarcoidosis (p < 0.0001). Stepwise regression analysis showed that presence of cardiac sarcoidosis, decreased ejection fraction and increased sPAP were all independently associated with higher plasma NT-proBNP levels. Plasma NT-proBNP showed good accuracy in identifying patients with cardiac sarcoidosis (area under the ROC curve; AURC = 0.913). However, even when patients with cardiac sarcoidosis were excluded, plasma NT-proBNP levels could not be used reliably to identify patients with PH (AURC = 0.681). CONCLUSION In patients with sarcoidosis, plasma NT-proBNP levels are a useful biomarker to identify cardiac involvement, but not to identify PH.

Abstract
Inhibition of the fermentation of acetate to methane and carbon dioxide by acetate was analyzed with an acetate-acclimatized sludge and with Methanosarcina barkeri Fusaro under mesophilic conditions. A second-order substrate inhibition model, q(ch(4) ) = q(m)S/[K(s) + S + (S/K(i))], where S was the concentration of undissociated acetic acid, not ionized acetic acid, could be applicable in both cases. The analysis resulted in substrate saturation constants, K(s), of 4.0 muM for the acclimatized sludge and 104 muM for M. barkeri. The threshold concentrations of undissociated acetic acid when no further acetate utilization was observed were 0.078 muM (pH 7.50) for the acclimatized sludge and 4.43 muM (pH 7.45) for M. barkeri. These kinetic results suggested that the concentration of undissociated acetic acid became a key factor governing the actual threshold acetate concentration for acetate utilization and that the acclimatized sludge in which Methanothrix spp. appeared dominant could utilize acetate better and survive at a lower concentration of undissociated acetic acid than could M. barkeri.

Abstract
Methanosarcina barkeri Fusaro (DSM 804) could grow on methanol in a mineral medium containing cysteine or thiosulfate as the sole sulfur source. Optimum growth occurred at cysteine concentrations of 1 to 2.8 mM and at thiosulfate concentrations of 2.5 to 5 mM. No inhibition of growth was observed even when these concentrations were doubled in the culture medium. Under the optimum cysteine and thiosulfate concentrations, the generation times of the organism were about 8 to 10 and 10 to 12 h, respectively, giving a cell yield of about 0.14 to 0.17 and 0.08 to 0.11 g (dry weight)/g of methanol consumed. The organism metabolized cysteine and thiosulfate during growth, giving rise to sulfide in the culture medium. H(2)S evolution from cysteine and thiosulfate was catalyzed by two enzymes, namely cysteine desulfhydrase and thiosulfate reductase, respectively, as revealed by enzyme assay in the crude cell-free extract of the organism.

Abstract
AIM The aim of this study was to examine the effectiveness of earlier continuous Kangaroo Mother Care (KMC) for relatively stable low-birth-weight (LBW) infants in a resource-limited country. METHODS A randomized controlled trial was performed in LBW infants at a referral hospital in Madagascar. Earlier continuous KMC (intervention) was begun as soon as possible, within 24 h postbirth, and later continuous KMC (control: conventional care) was begun after complete stabilization (generally after 24 h postbirth). Main outcome measure was mortality during the first 28 days postbirth. This trial was registered with ClinicalTrials.gov, NCT00531492. RESULTS A total of 73 infants (intervention 37, control 36) were included. Earlier continuous KMC had higher but no statistically different mortality in the first 28 days postbirth (1 vs. 2; risk ratio, 1.95; 95% CIs, 0.18-20.53; p = 1.00). There were no differences in incidence of morbidities. Body weight loss from birth to 24 h postbirth was significantly less in earlier KMC infants compared with later KMC infants. (-34.81 g vs. -73.97 g; mean difference, 39.16 g; 95% CIs, 10.30-68.03; p = 0.01; adjusted p = 0.02). Adverse events and duration of hospitalization were not different between the two groups. CONCLUSION Further evaluations of earlier continuous KMC including measurement of KMC dose, are needed in resource-limited countries.

Abstract
Abstract
Background: Some advanced cancer patients suffer from unpleasant odor from their fungating wounds. The fungating wounds have been reported to occur in about 5% of patients with cancer. These wounds are usually superinfected with bacteria, and therefore, the infected area tends to emit malodor. However, the odorant(s) causing the malodor has not been revealed. Here we aim to determine the chemical identity of the cancer wound-derived odor(s). Results: We examined three female patients with breast cancer (B1; stage IV, B2; stage IIIB, B3; stage IV) and two male patients with head and neck cancer (H1; stage III, H2; stage IVA). First, we evaluated the intensity and quality of body odors emitted from the fungating wounds of patients. All of them had a similar pungent sulfury odor. In addition to the sulfury odor, B1and B2 had a cheese-like odor and B3, H1 and H2 had a rotten fish odor. Next, we analyzed the malodor emitted from the wounds of each patient. Sterile gauze pads were placed on fungating wounds of the patients for 6-12h. The head-space volatiles of pads were extracted onto SPME fibers for 2h. The compounds on the SPME fibers were then analyzed by gas chromatography-mass spectrometry-olfactometry (GC-MS-O) that enabled us to examine mass spectra and odor qualities of individual GC-separated odorants simultaneously. GC-MS-O analysis and evaluation of body odors were performed by three persons. As a result, the sulfury odor, which was the same as the odor we identified in body odors of all patients, came out at the retention time (RT) of 19.46min. Cheese-like odors in B1 and B2 patients came out at RT=24.01min, 25.47min and 26.08min. The structure of dimethyl trisulfide (DMTS) was predicted by the mass spectrum of the peak around 19.5min. The mass spectrum and the RT of authentic DMTS were identical to those of the peak compound, demonstrating that the sulfury odor at 19.46min was DMTS. Comparing the odor quality and intensity of various concentrations of DMTS solutions and cancer samples, we conclude that DMTS is emitted from the cancer wounds at the level significant enough to make ones feel uncomfortable. We also identified the structure of compounds with cheese-like odors: isobutyric acid for the cheese odor (24.01min), butyric acid for the cheese and vomit odor (25.47min), and isovaleric acid for the cheese and feet odor (26.08min). Discussion: We identified DMTS as the main odorant that caused the severe malodor in some advanced cancer patients. DMTS has been found in volatiles emitted from vegetables such as cooked onion. DMTS is also reported to be produced by aerobes such as Pseudomonas aeruginosa that reside in leg ulcers. Thus, although the source of DMTS found in the fungating cancer wounds in this study remains to be elucidated, DMTS may be a product of infected bacteria in fungating wounds. To improve the QOL of patients, the development of the way to prevent or reduce the DMTS odor is awaited. Indeed, almost all patients with fungating wounds are suffering from this malodor. Our results provide new insights into the better strategies toward the treatment of malodor in cancer patients.

Abstract
Abstract
Background: New agents have improved systemic disease control, but the control of central nervous system (CNS) metastases is still insufficient. The identification of factors that may predispose to CNS metastases may help lead to earlier detection possibly to improvement in disease management.Methods: Patients (pts) with metastatic who were diagnosed with clinical stage I-III primary breast cancer at National Cancer Center Hospital East from January 2003 to December 2005 were screened. All pts with CNS metastases were identified by CT or MRI. Cox proportional hazards models were fitted to find risk factors of CNS metastases. Factors included age, menopausal status, clinical stage, T stage, histological grade, lymphovascular invasion, hormone and HER2 status, and Ki67 (at least 30% tumor cells positive). Survival was calculated by the Kaplan-Meier method.Results: Median follow-up from operation was 53.5 months. Of 591 breast cancer pts, 76 pts (12.9%) relapsed. Seventeen pts (2.9%) developed CNS metastases; 5 pts developed as the first recurrence site. Multivariable analysis indicated the higher risk for developing CNS metastases were triple negative (TN) tumors (HR 5.532, 95% CI 1.445-21.180, p=0.013) and Ki67 overexpression (HR 3.906, 95% CI 1.179-12.939, p=0.026). There were no statistically significant differences in other factors.

Abstract
BACKGROUND Chronic beryllium disease (CBD) is a rare disease, and there are no previous reports that have followed CBD patients over several decades. Thus, the long-term complications and prognosis of this illness still remain unclear. OBJECTIVE The aim of this study was to investigate long-term complications and prognosis of CBD patients. STUDY DESIGN AND METHODS This was a retrospective study based on the medical records of all CBD patients diagnosed at Kyoto University Hospital between the period 1973 to the present day. Ultimately, ten patients whose diagnoses had been made during the period 1973 to 1977 were included. Long-term physiological and radiological change, complications and prognosis of these patients were investigated. RESULTS Three patients completely remitted, and one died of cor-pulmonale. Among the remaining six patients, four have been followed up for more than thirty years in our institute. The majority developed mixed patterns of lung function impairment, cavity lesions of the lung, pneumothorax, and respiratory infections. CONCLUSIONS Long-term prognosis of CBD was poor with several complications due to chronic parenchymal and airway lesions.

Abstract
Abstract
Background
The aim of this study was to evaluate the effects of mild macrovesicular steatosis on the outcome of living liver donors following right hepatectomy.
Methods
The medical records of 46 living liver donors who underwent right hepatectomy were studied. Ten donors had mild macrovesicular steatosis (5–10 per cent in seven and 11–20 per cent in three patients). Five donors with other liver pathology were excluded. Outcome in these ten donors (group 1) was compared with that in the remaining 31 donors with normal liver histology (group 2).
Results
The median duration until normalization of total bilirubin levels was 14 and 5 days in groups 1 and 2 respectively (P = 0·028). The peak total bilirubin level was significantly higher in group 1 than in group 2 (80·4 versus 49·6 µmol/l; P = 0·033). Multivariable analysis showed mild macrovesicular steatosis to be an independent risk factor for hyperbilirubinaemia (odds ratio 7·94 (95 per cent confidence interval 1·17 to 54·03); P = 0·034).
Conclusion
Mild macrovesicular steatosis may be related to adverse outcome in living liver donors who undergo right hepatectomy and, in terms of donor safety, is of potential concern in donor selection.
