Abstract
Energy loss at a manhole which is at a junction of storm sewers or combined sewers is important for accurately estimating its discharge capacity. However, even in Japan, the energy loss at the manhole is usually ignored in designing sewers and flood inundation analysis. One of the reasons for the ignorance is difficulty to formulate the energy loss at the manhole because the number of variables which must be considered increases as the number of sewers connected to the manhole increases. The authors have formulated the energy loss of a four-way circular manhole with three inflow sewers and one outflow sewer at crossroad. The formula is applicable only to the equal flow rates in two opposite lateral inflow sewers. In this paper, a new formula for the energy losses is proposed based on experimental data on a four-way circular manhole with different flow rates on three inflow sewers. It shows that the energy losses calculated with it almost reproduce the measured ones.

Abstract
Study question
Can providing quality-assured fertility-related information via a smartphone application improve fertility- and treatment-related literacy among smartphone application users?
Summary answer
Provision of quality-assured fertility-related information via a smartphone application contributed to enhancing fertility- and treatment-related literacy among the smartphone application users.
What is known already
For infertility patients, the interpretation of examination results may be overly complicated and complex, and patients may have difficulty in making sense of their own fertility problems. Accessing and learning about fertility-related information using the Internet via smartphone is reasonable; however, the information does not always reflect evidence-based recommendations and low-quality information may lead to adverse effects on users; thus, innovative methods to provide both accessible and high-quality information are desired.
Study design, size, duration
We performed a randomized control-group pretest posttest study and 4,137 smartphone application users were invited to participate between June 18 and 25, 2020. Participants’ fertility treatment-related literacy were assessed with a pretest that comprised of 28 questions and participants were allocated with stratified randomization to either intervention or control group. The intervention comprised a one-week smartphone application-based provision of information on fertility- and treatment-related information and the control group received general information about women’s healthcare.
Participants/materials, setting, methods
The 3,765 participants (91.0 %) who responded were randomly allocated into either the intervention group (N = 1883) or the control group (N = 1882). Characteristics of participants appeared similar between the groups reflecting that the randomization was successful in producing a balance in baseline characteristics. Effectiveness of intervention was assessed using pretest-posttest analysis. Ethical approval was obtained from the Institutional Review Board of the National Center for Child Health and Development of Japan (approval number: 2019-184).
Main results and the role of chance
The posttest was completed by 659 participants (17.5%), and finally 207 participants in the intervention group and 222 participants in the control group were available for pretest-posttest analysis. Demographic characteristics of these participants appeared similar between the groups. In comparing the demographic characteristics of participants who did and did not complete the posttest, there were significant differences between the two groups in age, overall test score, proportion living with a partner, and action for pregnancy. For the posttest, the overall mean test scores were significantly higher in the intervention group compared to the control group (P = 0.0082). Interestingly, we also observed that posttest scores were significantly improved compared to pretest scores in both the intervention group and control group (P < 0.001). When examining by specific test question, the proportion answering correctly appeared to generally increase at posttest compared to pretest for intervention (P < 0.001) and control (P < 0.001) groups. There was over 10% improvement in 7 questions, and particularly, over 20% improvement for a question about clinical significance of anti-Müllerian hormone. Furthermore, directly comparing the difference in posttest versus pretest scores between the two groups showed, on average, greater improvements in the intervention group than the control group (P < 0.001).
Limitations, reasons for caution
As the intervention was educational material, it was not possible to blind participants to intervention group assignment. We were not able to monitor the participants when completing the tests; thus, whether they accessed other resources could not be addressed.
Wider implications of the findings
Providing information through a smartphone application can be considered acceptable since retrieving information through a smartphone application is in line with the current modern day lifestyle. A smartphone application may offer alternatives such as chatbots and movie-based learning, and they have the potential to increase the effectiveness.

Abstract
The Gynecologic Cancer InterGroup (GCIG) Fifth Ovarian Cancer Consensus Conference (OCCC) was held in Tokyo, Japan from 7 to 9 November 2015. It provided international consensus on 15 important questions in 4 topic areas, which were generated in accordance with the mission statement to establish 'International Consensus for Designing Better Clinical Trials'. The methodology for obtaining consensus was previously established and followed during the Fifth OCCC. All 29 clinical trial groups of GCIG participated in program development and deliberations. Draft consensus statements were discussed in topic groups as well as in a plenary forum. The final statements were then presented to all 29 member groups for voting and documentation of the level of consensus. Full consensus was obtained for 11 of the 15 statements with 28/29 groups agreeing to 3 statements, and 27/29 groups agreeing to 1 statement. The high acceptance rate of the statements among trial groups reflects the fact that we share common questions, and recognise important unmet needs that will guide future research in ovarian cancer.

Abstract
This manuscript reports the consensus statements regarding recurrent ovarian cancer (ROC), reached at the fifth Ovarian Cancer Consensus Conference (OCCC), which was held in Tokyo, Japan, in November 2015. Three important questions were identified: (i) What are the subgroups for clinical trials in ROC? The historical definition of using platinum-free interval (PFI) to categorise patients as having platinum-sensitive/resistant disease was replaced by therapy-free interval (TFI). TFI can be broken down into TFIp (PFI), TFInp (non-PFI) and TFIb (biological agent-free interval). Additional criteria to consider include histology, BRCA mutation status, number/type of previous therapies, outcome of prior surgery and patient reported symptoms. (ii) What are the control arms for clinical trials in ROC? When platinum is considered the best option, the control arm should be a platinum-based therapy with or without an anti-angiogenic agent or a poly (ADP-ribose) polymerase (PARP) inhibitor. If platinum is not considered the best option, the control arm could include a non-platinum drug, either as single agent or in combination. (iii) What are the endpoints for clinical trials in ROC? Overall survival (OS) is the preferred endpoint for patient cohorts with an expected median OS < or = 12 months. Progression-free survival (PFS) is an alternative, and it is the preferred endpoint when the expected median OS is > 12 months. However, PFS alone should not be the only endpoint and must be supported by additional endpoints including pre-defined patient reported outcomes (PROs), time to second subsequent therapy (TSST), or time until definitive deterioration of quality of life (TUDD).

Abstract
This manuscript reports the consensus statements on designing clinical trials in rare ovarian tumours reached at the fifth Ovarian Cancer Consensus Conference (OCCC) held in Tokyo, November 2015. Three important questions were identified concerning rare ovarian tumours (rare epithelial ovarian cancers (eOC), sex-cord stromal tumours (SCST) and germ cell tumours (GCT)): (i) What are the research and trial issues that are unique to rare ovarian tumours? There is a lack of randomised phase III data defining standards of care which makes it difficult to define control arms, but identifies unmet needs that merit investigation. Internationally agreed upon diagnostic criteria, expert pathological review and translational research are crucial. (ii) What should be investigated in rare eOC, GCT and SCST? Trials dedicated to each rare ovarian tumour should be encouraged. Nonetheless, where the question is relevant, rare eOC can be included in eOC trials but with rigorous stratification. Although there is emerging evidence suggesting that rare eOC have different molecular profiles, trials are needed to define new type-specific standards for each rare eOC (clear cell, low grade serous and mucinous). For GCTs, a priority is reducing toxicities from treatment while maintaining cure rates. Both a robust prognostic scoring system and more effective treatments for de novo poor prognosis and relapsed GCTs are needed. For SCSTs, validated prognostic markers as well as alternatives to the current standard of bleomycin/etoposide/cisplatin (BEP) should be identified. (iii) Are randomised trials feasible? Randomised controlled trials (RCT) should be feasible in any of the rare tumours through international collaboration. Ongoing trials have already demonstrated the feasibility of RCT in rare eOC and SCST. Mucinous OC may be considered for inclusion, stratified, into RCTs of non-gynaecological mucinous tumours, while RCTs in high risk or relapsed GCT may be carried out as a subset of male and/or paediatric germ cell studies.

Abstract
During orthodontic tooth movement, mechanical stresses induce inflammatory reactions in the periodontal ligament (PDL). We hypothesized that chemokines released from PDL cells under mechanical stress regulate osteoclastogenesis, and investigated the profiles and mechanisms of chemokine expression by human PDL cells in response to mechanical stress. In vitro, shear stress and pressure force rapidly increased the gene and protein expressions of IL-8/CXCL8 by PDL cells. Consistently, amounts of IL-8 in the gingival crevicular fluid of healthy individuals increased within 2 to 4 days of orthodontic force application. The PDL cells constitutively expressed low levels of IL-1β, which were not further increased by mechanical stress. Interestingly, neutralization of IL-1β abolished IL-8 induction by mechanical stresses, indicating that IL-1β is essential for IL-8 induction, presumably though autocrine or paracrine mechanisms. Finally, experiments with signal-specific inhibitors indicated that MAP kinase activation is essential for IL-8 induction.

Abstract
BACKGROUND The efficacy of tapentadol extended release (ER) for managing chronic pain has been demonstrated in large-scale, randomized, controlled, phase 3 studies (N=318-1,030) in patients with chronic osteoarthritis (OA) pain, low back pain (LBP), and pain related to diabetic peripheral neuropathy (DPN), which led to registration in many regions, including the United States and Europe. 2 pilot 12-week, randomized, double-blind, placebo-controlled phase 2 studies of tapentadol ER for chronic pain (OA knee pain or LBP, n=91; DPN or peripheral herpetic neuralgia [PHN] pain; n=91) were conducted in Japan. These small exploratory studies were substantially underpowered compared with the registration trials. METHODS Patients in both studies were randomized (2:1) to tapentadol ER (25-250 mg) or placebo for 12 weeks (≤6-week titration plus maintenance periods). RESULTS For the primary efficacy endpoint (change in pain intensity from baseline to last week of treatment; last observation carried forward), both studies failed to differentiate between tapentadol ER and placebo; least-squares mean differences (95% confidence intervals) for tapentadol ER vs. placebo were -0.1 (-1.04, 0.80) in the OA/LBP study and -0.1 (-1.10, 0.99) in the DPN/PHN study. More than 80% of patients took concomitant analgesics during these studies. Tapentadol was well tolerated. CONCLUSIONS Both studies were associated with methodological issues, including populations with different disease entities, small sample sizes, use of concomitant analgesics, and possible placebo effect that may have led to the failure to differentiate between tapentadol ER and placebo.

Abstract
INTRODUCTION Villitis of unknown etiology (VUE) is associated with fetal growth restriction. However, the underlying mechanisms of villous injury in placentas with VUE are still largely unknown. We aimed to verify whether apoptosis-related factors are increased in VUE placentas. Furthermore, we determined apoptosis of villous cells. METHODS Six placentas with VUE and 3 control placentas were stained using immunohistochemistry with antibodies for CD3, CD4, CD8, CD68, CD163, perforin, granzyme B, granzyme K, and C5b-9. TUNEL assay analysis was also performed with these placentas. The percentage of cells that stained positive, CD163/CD68 ratio, percentage of C5b-9 positive area, and apoptosis index were quantified and compared between the inflammatory lesions of the VUE placentas, non-VUE inflammatory lesions of the VUE placentas, and control placentas. RESULTS The percentages of CD3, CD4, CD8 CD68, CD163, perforin, and granzyme B positive cells were significantly higher in the inflammatory lesions of the VUE placentas (p < 0.05). The intravillous CD163/CD68 ratio was higher in the inflammatory lesions compared with the non-inflammatory lesion of the VUE placentas (p < 0.05). The percentage of granzyme K-positive cells was not significantly different between the groups. C5b-9 deposition was higher in the inflammatory lesions of the VUE placentas (p < 0.05). TUNEL-positive cells were significantly higher in the inflammatory lesions of the VUE placentas (p < 0.05). DISCUSSION To the best of our knowledge, this is the first report to assess villous injury, especially from a viewpoint of villous apoptosis in VUE placentas. An activated perforin/granzyme pathway and C5b-9 are suggested as possible mechanisms of apoptosis.

Abstract
BACKGROUND The development of immunosuppressive techniques has helped overcome the ABO incompatibility barrier. However, the outcomes of ABO-incompatible (ABOi) kidney transplantation remain a controversial issue with the advent of the anti-CD20 chimeric antibody rituximab. Herein, we report the outcomes of ABOi kidney transplantation with low-dose rituximab. PATIENTS AND METHODS Between June 2006 and April 2013, 42 patients underwent living-related kidney transplantation at our hospital. The patients were divided into 2 groups: ABO-compatible (ABOc; n = 29) and ABOi kidney transplants using low-dose rituximab (100 mg/m(2)) without splenectomy (n = 13). The basic immunosuppression regimen (calcineurin inhibitor [CNI], mycophenolate mofetil [MMF], and steroids) was the same for both groups, except for the use of rituximab and therapeutic apheresis in the ABOi group. We compared post-transplantation renal function, incidents of virus infection, episodes of rejection, and graft survival between the 2 groups. RESULTS In our hospital, 30% of recipients received ABOi kidney transplants. The estimated glomerular filtration rate (eGFR) did not differ between the groups. Rejection episodes confirmed by biopsy in the ABOc and ABOi groups were 8 (28%) and 4 (31%) patients (P = .833), acute antibody-mediated rejection was observed in 1 (3.5%) and 2 (15%) patients (P = .165), and virus infection was observed in 14 (48%) and 3 (23%) patients (P = .252), respectively. The 5-year patient survival rate was 100% in both groups, and the 5-year graft survival rates were 95% for ABOc and 100% for ABOi transplants (P = .527). CONCLUSIONS These results suggest that the outcomes of ABOi kidney transplantation with low-dose rituximab are similar to those of ABOc kidney transplantation. Further study is necessary to address the efficacy and safety of ABOi kidney transplantation.

Abstract
INTRODUCTION The aortic calcification index (ACI) is reported to be closely associated with renal dysfunction and cardiovascular events; however, its implication in renal transplant recipients has not been well examined. In this study, we investigated the relationship between pretransplant ACI, ACI progression, post-transplant renal function, and post-transplant cardiovascular events in renal transplant recipients. PATIENTS AND METHODS The study from June 1996 to Jan 2012 included 61 renal transplant recipients (living donors, 47; cadaveric donors, 14). The median follow-up period was 60 months. ACI was quantitatively measured on abdominal computed tomography. The relationship between age, dialysis period, estimated glomerular filtration rate (eGFR), and pre- and post-transplant ACI was longitudinally evaluated. Risk factors for post-transplant ACI progression were determined by logistic regression analysis. Patient background and the incidence of post-transplant cardiovascular events were also assessed. RESULTS The pretransplant ACI (median 4.2%) significantly correlated with age at transplant, dialysis period, and diabetes mellitus. ACI gradually increased up to 2.8 times at 10 years after transplantation. Post-transplant eGFR significantly correlated with ACI progression in patients with chronic kidney disease of stage ≥ 3. Logistic regression analyses showed that age at transplantation, post-transplant period, cadaveric donors, and post-transplant chronic kidney disease stage 3 were risk factors for post-transplant ACI progression. The pretransplant ACI was higher (median 66%) in 3 patients who experienced post-transplant cardiovascular events. CONCLUSIONS ACI progression closely correlates with age and post-transplant renal function. A high pretransplant ACI is a risk factor for post-transplant cardiovascular events in renal transplant recipients.

Abstract
A helium ion beam is injected into a linear plasma device for the development of an ion beam source simulating high energy particle flux in divertor plasma. Beam current density more than 10 mA/cm(2) is extracted. Measurement of beam currents indicates that the beam is transported along the linear device and reaches to the downstream end plate.

Abstract
To develop a compact ion injector made of hydrogen storage material, we investigate a plasma response for a positively biased hydrogen storage electrode in a small standard heliac device. When the bias voltage of the electrode increases, a positive potential between the electrode and the space potential on the magnetic surface emerges. The emission of hydrogen atom line also increases. To clarify the origin of the increase in emission, we designed an imaging system with sufficient temporal resolution.

Abstract
Angle-resolved energy distribution functions of positive and negative hydrogen ions produced from a rough-finished Si surface under 1 keV proton irradiation have been measured. The corresponding distribution from a crystalline surface and a carbon surface are also measured for comparison. Intensities of positive and negative ions from the rough-finished Si are substantially smaller than those from crystalline Si. The angular distributions of these species are broader for rough surface than the crystalline surface. No significant temperature dependence for positive and negative ion intensities is observed for all samples in the temperature range from 300 to 400 K.

Abstract
SH2D1A, also known as signaling lymphocytic activation molecule (SLAM)-associated protein (SAP), is an adaptor protein. Recently, it was reported that SAP deficient mice were protected from systemic lupus erythematosus (SLE). In this study, we postulated SH2D1A gene to be a candidate susceptibility gene for SLE and analyzed its association with SLE. A case-control association study was conducted on 5 tag single nucleotide polymorphisms (SNPs) in SH2D1A region in 506 Japanese female SLE patients and 330 healthy female controls. The luciferase assay was performed to determine the functional role of the SNP associated with SLE. One SNP in the intron 2, rs2049995, showed association with SLE (p=0.0110, odds ratio (OR) 1.97, 95% confidence interval (CI) 1.16-3.34, under the dominant model). The association of rs2049995 seemed to be stronger in the subset with the age of onset less than 20 years (p=0.0067, OR 2.65, 95% CI 1.28-5.46). Functional evaluation of rs2049995 showed that reporter gene activity was increased 1.9-fold for the susceptible allele compared with the resistant allele. An intronic SNP of SH2D1A is associated with SLE.

Abstract
Choriocarcinoma is categorized as either gestational or nongestational depending on its origin. Nongestational choriocarcinoma originated in the trophoblastic differentiation is a rare but an aggressive tumor. This article reports a nongestational case of a uterine endometrial carcinoma with trophoblastic differentiation. A 54-year-old woman with a history of atypical genital bleeding that underwent semi-radical hysterectomy, bilateral salpingo-oophrectomy, and pelvic lymph nodes dissection. Pathological investigation showed that the tumor had endometrioid adenocarcinoma and choriocarcinomatous components. Although a series of multimodality treatments including craniotomy were performed, she died of aggressive lung and brain metastases one year after the primary surgery.

Abstract
Salmonella ovarian abscess in a patient with rheumatoid arthritis (RA) is reported here. A 33-year-old nulliparous woman with a 16-year history of RA who had been treated with corticosteroid and immunosuppressive drugs was diagnosed as having a non-typhoidal Salmonella ovarian abscess which might have been preceded by an occurrence of endometriotic cyst. Multidisciplinary therapy including surgical intervention was required to complete the eradication of infection. Although Salmonella ovarian abscess is rare, it may cause a serious complication in the ovary harboring endometriotic cyst through sustained presence of Salmonella bacteraemia.

Abstract
INTRODUCTION Extravillous trophoblast (EVT) cell invasion plays a crucial role in establishment of successful pregnancy. CD44, a cell-surface receptor for hyaluronic acid (HA), plays a key role in HA-mediated remodeling and degradation that triggers cancer cell invasion. However, few studies have reported on the expression or functions of CD44 in human EVT cells. We hypothesized that CD44-HA interaction was involved in invasion by EVT cells. METHODS To test our hypothesis, we conducted in situ examinations of CD44 and HA expression in the human first-trimester placenta. We also assessed the methylation status of CD44 promoter and exon 1 regions in EVT cells. Finally, we conducted transwell cell invasion assays using EVT cell lines and EVT cells isolated from first-trimester human villous explant cultures. RESULTS AND DISCUSSION EVT cells, but not villous trophoblast cells, in the first-trimester placenta expressed CD44. HA was strongly expressed in adventitia surrounding the spiral uterine arterial walls of the decidua. The extent of demethylation of CD44 promoter and exon 1 CpG islands was increased in EVT cells compared to those of first-trimester chorionic villi (including villous trophoblast cells), suggesting that CD44 expression was, at least in part, associated with methylation status. Data from transwell cell invasion assay with siRNA knockdown of CD44 revealed that CD44 expression significantly promoted invasion by EVT cells in an HA-dependent manner. CONCLUSIONS The discovery of a CD44-HA interaction between EVT cells and the extracellular matrix contributes to our understanding of the mechanism underlying invasion by EVT cells.

Abstract
Mycobacterium florentinum is a newly identified, rare, slow-growing species of nontuberculous mycobacteria (NTM). Here, we report a case of M. florentinum-induced synovitis of the wrist in an immunocompromised Japanese patient. M. florentinum was identified by sequence analysis of the rpoB, hsp65, and 16S rRNA genes. The M. florentinum strain in this study could not be differentiated from certain M. triplex strains by the hsp65 or 16S rRNA sequences alone, because they occasionally shared more than 99 % sequence identity. The isolated M. florentinum strain was only susceptible to clarithromycin and amikacin. Initially, the patient was treated with clarithromycin, levofloxacin, and ethambutol, and then with clarithromycin, levofloxacin, and rifampicin. To our knowledge, M. florentinum-induced synovitis has not been previously reported. Our results suggest that, in addition to other well-known pathogenic NTM, the recently identified M. florentinum strain should be considered as a possible cause of synovitis. Moreover, we should be cautious when identifying M. florentinum because this strain closely resembles M. triplex in genotype.
