Abstract
Abstract
Background: Dedicated breast positron emission tomography (DbPET)provides detailed high resolution images of the breast and enables quantitative assessment using standard uptake values (SUVs). We aimed to determine whether DbPET can predict the pathological malignancy grade and neoplastic progress of breast cancer compared with whole body (WB) PET.
Methods: We investigated 196 consecutive patients with invasive breast cancerwho underwent concurrent Db- and WB-PET from January 2016 to March 2017. All Db- and WB-PET were quantified based on SUVs. We also investigated pathological features of breast cancer who had a ring-like uptake (RU) without central FDG accumulation on DbPET.

Abstract
Abstract
Background: Whole body (WB) 18F-fluorodeoxyglucose positron emission tomography (PET) has a relatively poor spatial resolution (>1 cm), which limits the capability to detect small lesions. Therefore, small-sized breast cancers (≤1 cm) may not be visible on WBPET. To overcome these limitations, dedicated breast PET (DbPET) has been developed to improve spatial resolution. DbPET enables detailed high-resolution images within the breast. We aimed to determine whether DbPET can detect small-sized breast cancer compared to WBPET.
Methods: We investigated 203 consecutive patients (217 tumors) (T1–3, N0–3a, M0) with breast cancer who underwent concurrent DbPET and WBPET between January 2016 and March 2017. All DbPET and WBPET images were semi-quantified based on standard uptake values. The diagnostic performance of each scanner was assessed in DbPET and WBPET. Tumors were classified based on pathological classification as follows: Tis, ductal carcinoma in situ (DCIS); T1a, ≤0.5 cm; T1b, 0.5–1 cm; and T1c, 1–2 cm; T2, 2–5 cm; T3, >5 cm. The sensitivities of DbPET and WBPET were compared in each size group.
Results: Table 1 shows the detection rate of breast cancer in WBPET and DbPET

. The overall detection rate in DBPET [93.1% (202/217)] was significantly higher than that of WBPET [78.3% (170/217)] (P < 0.001). For smaller tumors, DbPET was more sensitive than WBPET: Tis (85.4% vs. 56.1%), T1a (92% vs. 72%), T1b (93.5% vs. 67.7%), T1c (91.8% vs. 82%), T2 (100% vs. 98.2%), and T3 (100% vs. 100%). The sensitivity of DbPET was significantly higher than that of WBPET in Tis (P = 0.003) and T1b (P = 0.008) and tended to be higher than that of WBPET in T1a (P = 0.059). Conversely, no significant differences were observed in T1c (P = 0.103) and T2 (P = 0.238).
Conclusion: The imaging sensitivity of DbPET was higher than that of WBPET. DbPET showed significant sensitivity in DCIS and tumors ≤1 cm, which is a weak point for WBPET. DbPET may serve as a new diagnostic modality to detect small-sized breast cancer.

Abstract
Summary
Objectives:
Activity-based costing (ABC) is widely used to precisely allocate indirect costs to medical services. In the ABC method, the indirect cost is divided among the medical services in proportion to the volume of “cost drivers”, for example, labor hours and the number of hours of surgery. However, the workload of data collection of cost drivers can be time-consuming and a considerable burden if there are many cost drivers. The authors aim to develop a method for objectively reducing the cost drivers used in the ABC method.
Methods:
In the ABC method, the cost driver is assigned for each activity. We assume that these activities and cost drivers are the best combination. Our method, that is cost driver reduction (CDR), can objectively select surrogates of the cost drivers for each activity in ABC from candidate cost drivers. Concretely, the total indirect cost of an activity is temporarily allocated to the medical services using each candidate of cost drivers. The difference between the costs calculated by each candidate and the proper cost driver used in ABC is calculated to evaluate the similarity by the evaluation function.
Results:
We estimated the cost of laboratory tests using our method and revealed that the number of cost drivers could be reduced from seven in the ABC to four. Similarly, the results of cost estimation obtained by our method were as accurate as those calculated using the ABC.
Conclusions:
Our method provides two advantages compared to the ABC method: 1) it provides results that are as accurate as those of the ABC method, and 2) it is simpler to perform complicated estimation of hospital costs.

Abstract
Solitary mediastinal lymph node metastasis of hepatocellular carcinoma (HCC) is rare. We report a case of metachronically solitary mediastinal metastases of HCC treated by video-assisted thoracic surgery (VATS) twice. A 66-year-old man underwent repeated laparoscopic radiofrequency ablation or trans-arterial catheter chemo-embolization against HCC for more than 10 years. The level of alpha fetoprotein protein was elevated, and radiological modalities including FDG-PET revealed solitary mediastinal tumor metachronically. VATS was performed bilaterally twice. The postoperative course was uneventful and there had no recurrence of extra-hepatic metastases and tumor markers are within normal limits at 18 months after second VATS. VATS is a minimally invasive and useful procedure for solitary mediastinal lymph node metastasis of HCC. If primary HCC was controlled and lymph node metastasis was solitary, mediastinum lymphadenectomy using VATS might give good short and long term results.

Abstract
Atypical hemolytic uremic syndrome (aHUS) develops as the result of unregulated complement progression and precipitates de novo thrombotic microangiopathy. Plasma therapy is used to control the progression of the complement cascade, but that therapy is not effective in all patients and is accompanied by risk of infection and/or allergy. Eculizumab has been reported as an efficient therapy for aHUS. We report the case of a 35-year old woman who underwent effective eculizumab therapy for aHUS recurrence and antibody-mediated rejection (AMR) progress after renal transplantation with preformed donor-specific antibodies (DSA). She developed end-stage renal disease due to suspicious IgA nephropathy at age 33 years. Kidney transplantation was performed at age 35 years, and aHUS recurred 2 weeks later, leading to the progressive hemolytic anemia and renal dysfunction. Therefore, she underwent plasma therapy several times. Because it was difficult to continue to plasma therapy for severe allergy, eculizumab was proposed as an alternate therapy. Treatment with eculizumab was initiated 36 days after renal transplantation. After 3 years of eculizumab treatment, and without plasma therapy, schistocytes decreased, haptoglobin increased to within normal limits, creatinine levels stabilized, and no further episodes of diarrhea were reported. At protocol biopsy 1 year after transplantation, she was diagnosed with C4d-negative subclinical AMR. However, her pathologic findings at follow-up biopsy 3 years after transplantation were recovered. We conclude that eculizumab alone, without plasma therapy, is sufficient to treat recurrence of aHUS and AMR due to DSA after renal transplantation and to maintain long-term graft function.

Abstract
A 46-year-old woman was referred to our hospital because of nausea. Endoscopy revealed scirrhous gastric cancer, and abdominalcomputed tomography revealed peritonealdissemination. She was diagnosed with Stage IV gastric cancer and treated with S-1 plus CDDP combination chemotherapy. After 4 courses of chemotherapy, the primary tumor and peritoneal dissemination were considered clinically stable, but the uterus grew rapidly. She was diagnosed as having uterine metastasis based on cervicaland endometrialsmear class V cytology. As the chemotherapy was not effective for the uterine lesions, totalhysterectomy and bilateralsal pingo-oophorectomy were performed. Histological findings showed a poorly differentiated cancer with vascular emboli. Uterine metastases are an important consideration in women with scirrhous gastric cancer, and we recommend palliative hysterectomy for chemotherapy-resistant metastases if the primary tumor and other metastases are controlled.

Abstract
AIM Progranulin (PGRN) is a novel adipocytokine with anti-inflammatory effects in vascular cells. The aim of this study was to clarify the effects of PGRN on reactivity of isolated blood vessel. METHODS Isometric contraction of rat isolated superior mesenteric artery was measured. RESULTS Pre-treatment with PGRN (10-100 ng mL-1 , 30 min) had no effect on noradrenaline- or 5-hydroxytriptamine-induced contraction. On the other hand, pre-treatment with PGRN (100 ng mL-1 ) augmented acetylcholine (ACh; 30 nm)-induced endothelium-dependent relaxation. Pre-treatment with PGRN (100 ng mL-1 ) augmented ACh (10 μm)-induced nitric oxide (NO)-mediated relaxation in the presence of indomethacin (10 μm), a cyclooxygenase inhibitor, and tetraethyl ammonium (10 mm), a non-selective potassium channel blocker. In contrast, pre-treatment with PGRN (100 ng mL-1 ) had no effect on ACh-induced endothelium-derived hyperpolarizing factor-mediated relaxation. Pre-treatment with PGRN (100 ng mL-1 ) had no effect on ACh (10 μm, 1 min)-induced endothelial NO synthase phosphorylation (at Ser1177) as determined by Western blotting. Pre-treatment with PGRN (100 ng mL-1 ) augmented an NO donor, sodium nitroprusside (SNP; 30 nm-1 μm)- but not a membrane-permeable cGMP analogue, 8-bromo-cGMP-induced relaxation. In the presence of 3-isobutyl-1-methylxanthine (100 μm), a phosphodiesterase inhibitor, pre-treatment with PGRN (100 ng mL-1 ) increased SNP (30 nm, 5 min)-induced cGMP production as determined by enzyme immunoassay. CONCLUSION We for the first time demonstrate that PGRN augments ACh-induced NO-mediated relaxation through the increases of cGMP production in smooth muscle. These results indicate PGRN as a possible pharmacotherapeutic target against cardiovascular diseases including obesity-related hypertension.

Abstract
Abstract
Objectives
We aimed to determine whether contrast-enhanced ultrasonography (CEUS) can predict the early effects of neoadjuvant chemotherapy on triple negative breast cancer.
Methods
The clinical responses of 20 consecutive patients with breast cancer (T1–2, N0–1, M0) to neoadjuvant chemotherapy between October 2012 and Feb 2016 were assessed using ultrasonography and contrast-enhanced ultrasonography before starting the therapy and after the treatment of 2 courses. Ascending slope (AS) of perfusion parameters for contrast-enhanced ultrasonography were created from time–intensity curves based on enhancement intensity and temporal changes to objectively evaluate contrast-enhanced ultrasonography findings.We investigated whether rate of change of ascending slope (ΔAS) and tumor size (Δ US) could predict pCR.
Results
Eight (40.0%) of the 20 patients achieved pathological complete response. ΔAS were significantly higher (-25.5 ± 35.5 vs. 14.7 ± 33.2; P < 0.02) in patients who achieved pCR than in those who did not. On the other hand, ΔUS of pCR and non-pCR did not significantly differ among tumors (-40.8 ± 22.4 vs. -21.4 ± 20.6; P = 0.06). The AUC values for ΔAS and ΔUS were 0.792 (95% CI, 0.579 -1.000, P = 0.03) and 0.729 (95% CI, 0.501 - 0.957;p = 0.09), respectively. We set ΔAS and Δ US cut-offs for predicting pCR at-20.08 and - 33.75 based on the ROC curves. Clinical and pathological characteristics of the 20 patients are summarized in Univariate (odds ratio, 2.71; p= 0.02) and multivariate (odds ratio, 2.88; p= 0.03) analysis showed that ΔAS was the sole independent predictor of pCR.

Pre-operative Assessment of Psychological Characteristics and Mood States in Living Donor Kidney and Liver Transplantation. Transplant Proc 2017; 48:1018-21.

Abstract
BACKGROUND Past studies have indicated that psychological problems in both transplant recipients and donors increase during the pre-operative period. However, few studies have evaluated the pre-operative psychological status of both the recipient and the donor. METHODS This study included the donors and recipients of 36 adult living donor kidney transplants (LDKT) and 12 adult living donor liver transplants (LDLT) between January 2012 and December 2014. Their personalities were assessed using the Tokyo University Egogram (TEG) and the Yatabe-Guilford Personality Inventory (Y-G), while their mood states just before transplantation were evaluated via the Profile of Mood States (POMS). RESULTS On the TEG, the mean Adapted Child (AC) score of the LDLT recipient group was significantly lower than that of the LDKT recipient group. On the Y-G, no differences in the distribution of the five personality types were recognized among the four groups. POMS depression scores in the LDLT recipient group were significantly higher compared with the other groups. CONCLUSION LDLT recipients exhibited a depressive mood just before transplantation, and also had a low AC score. Therefore, clinicians should pay careful attention to potential medical non-adherence and post-operative depression in LDLT recipients. Based on these pre-operative assessments of personality and mood states, the transplant team should include post-operative care to support the quality of life of the recipients as well as the donors.
