Abstract
Nitrogen source assimilation is important for the biological functions of fungi, and its pathway has been deeply studied. Aspergillus oryzae mutants defective in nitrogen source assimilation are known to grow poorly on Czapek-Dox (CD) medium. In this study, we found an industrial strain of A. oryzae that grew very poorly on a CD medium containing sodium nitrate as a nitrogen source. We used media with various nitrogen components to examine the steps affecting the nitrogen source assimilation pathway of this strain. The strain grew well on the CD medium supplied with nitrite salt or ammonium salt, suggesting that the strain was defective in nitrate assimilation step. To ascertain the gene causing the defect of nitrate assimilation, a gene expression vector harboring either niaD or crnA of A. oryzae RIB40 was introduced into the industrial strain. The industrial strain containing the crnA vector recovered its growth. This is the first report that a mutation of crnA causes poor growth on CD medium in an industrial strain of A. oryzae, and crnA can be used as a transformation marker for crnA deficient strains.

Abstract
Koji mold, classified in the genus Aspergillus, is used to produce traditional Japanese fermented foods such as miso, soy sauce, and sake. In recent years, the application of koji mold to cheese ripening has attracted attention, and cheese surface-ripened with koji mold (koji cheese) has been studied. In this study, to evaluate the taste characteristics of koji cheese, an electronic tongue system was employed to measure the taste values of cheese samples ripened using 5 strains of koji mold in comparison with commercial Camembert cheese. All koji cheese samples exhibited lower sourness and greater bitterness, astringency, saltiness, and umami richness than the Camembert cheese samples. The intensity of each taste characteristic differed depending on the koji mold strain. These results indicate that koji cheese has a different taste value than conventional mold-ripened cheese. Furthermore, the results also indicate that various taste characteristics can be achieved by selecting different koji molds.

Abstract
While chicken eggs contain many nutrients necessary for humans and there are various cooking methods, the nutritional components are used as they are, and there are no traditional foods that utilize microorganisms. Koji-mold, containing Aspergillus oryzae, A. sojae, and A. luchuensis, which has been used in various fermented foods since ancient times, grows on raw grain materials such as rice and barley to become koji. This can give flavors not found in the raw materials that can decompose and convert the nutritional components of the raw materials. Here, we succeeded for the first time in developing egg-koji that uses only eggs and koji-mold by selecting and combining cooked egg powder (CEP) and A. oryzae AO101 as the most suitable combination. To suppress the explosive growth of harmful bacteria, we improved the sterilization method, watering method, and amount of water. In addition, it was found that egg-koji has a characteristic enzyme activity balance, in which amylase is extremely low and protease at pH 6 was high compared to grain koji, such as rice and barley. Egg-koji might produce enzymes suitable for taking in nutrients when growing into CEP and would be expected to give a flavor that could not be achieved by cooking or additives.

Abstract
An experimental implementation for the reduction of power-line noise in delicate signal detection is presented. This implementation improves the signal-to-noise ratio without limiting the bandwidth of the measurement. A sinusoidal wave and its harmonics, both synchronized with the frequency of the power line, are used to cancel out the power supply noise induced in the measurement signal. The wave and the harmonics are generated via a phase-locked loop implementation. Their amplitude and phase are adjusted, and then they are added to the measurement signal using a series of operational amplifiers to compensate for the noise. Although we applied this method to the particular case of scanning tunneling microscopy measurements, considerably improving the image quality, our implementation can be applied to other measurement systems for which noise from the power lines can compromise the signal detection.

Abstract
Abstract
Study question
Does the area of oocyte perivitelline space have an effect on fertilization and embryo development following intracytoplasmic sperm injection?
Summary answer
The area of oocyte perivitelline space has not an effect on the fertilization but the embryo development following intracytoplasmic sperm injection.
What is known already
Oocyte perivitelline space has a lot of variation at intracytoplasmic sperm injection (ICSI). Some researchers reported that the characteristics of perivitelline space (large or small) affect embryo development, pregnancy, and implantation. However, these studies did not accurately calculate the area of perivitelline space. Therefore, little information is available on the effect of the area of oocyte perivitelline space on fertilization and embryo development following ICSI. The purpose of this study was to calculate and classify the area of oocyte perivitelline space and investigate the effect of the area of perivitelline space on fertilization and embryo development following ICSI.
Study design, size, duration
1. We retrospectively investigated 634 mature oocytes that were conducted ICSI between January 2021 and December 2021. The area of each oocyte perivitelline space was defined from between the area of circle calculated from the inner layer of zona pellucida and cytoplasm and divided into 3 groups (-9%, 10-19%, 20%-).
2. We retrospectively calculated the diameter of an inner layer of zona pellucida and cytoplasm and compared it with the 3 groups (-9%, 10-19%, 20%-).
Participants/materials, setting, methods
1. The fertilization, survival, good quality day-3 embryo, blastocyst, good quality blastocyst rates following ICSI were compared with the 3 groups (-9%, 10-19%, 20%-).
2. The average diameter of an inner layer of zona pellucida and cytoplasm of each oocyte for the 3 groups (-9%, 10-19%, 20%-) were compared.
The data were analyzed by Fisher’s exact test, residual analysis, one-way ANOVA test, with Bonferroni correction as appropriate to determine the statistical differences among groups.
Main results and the role of chance
1. The survival rates of perivitelline space -9%, 10-19%, 20%- groups were 100% (109/109), 96% (363/378), 94% (138/147), the fertilization rates were 89% (97/109), 88% (331/378), 86% (127/147), the good quality day-3 embryo rates were 56% (54/97), 70% (232/331), 70% (89/127) respectively. No significant difference was observed between these comparison items. The blastocyst rates of perivitelline space -9%, 10-19%, 20%- groups were 51% (47/92), 69% (222/321), 82% (93/114), the good quality blastocyst rates were 22% (20/92), 40% (129/321), 52% (59/114) respectively. The blastocyst and good quality blastocyst rates of perivitelline space -9% group showed significantly lower results. On the other hand, the blastocyst and good quality blastocyst rates of perivitelline space 20%- group showed significantly higher results.
2. The average diameter of an inner layer of zona pellucida of perivitelline space -9%, 10-19%, 20%- groups were 125 ± 4 µm, 129 ± 5 µm, 136 ± 6 µm, the average diameter of the cytoplasm of perivitelline space were 121 ± 4 µm, 119 ± 4 µm, 118 ± 4 µm respectively. Significant differences were observed in all pairs of groups of the average diameter of an inner layer of zona pellucida and cytoplasm.
Limitations, reasons for caution
The area of oocyte perivitelline space was calculated at only one plane.
Wider implications of the findings
Oocytes with narrow perivitelline space might have a wide region of adhesive between the cytoplasm surface and an inner layer of the zona pellucida which resulted in a smaller diameter of the zona pellucida and lower blastocyst rate by forming cytoplasmic fragments (Yumoto K et al. JARG. 2020 ;37(6):1349-1354.).

Abstract
BACKGROUND To verify the usefulness of single assistant robotic surgery (SA-RS) using da Vinci Xi or X performed for total hysterectomy. METHODS The SA-RS group (S-group) includes surgeries in which the surgeon performed all surgical operations other than that of the uterine manipulator, while the dual assistant robotic surgery group (D-group) includes surgeries performed by the surgeon with two assistants. In S-group, the forceps and camera were replaced during surgery in cases of a large uterus with limited range of motion of the instrument. A comparative study of patient background, intraoperative and postoperative results and surgery-related cost was performed between the two groups. RESULTS No significant differences were observed between the two groups. On the contrary, S-group showed a significant reduction in preparation time and wound closure time, and a savings of $768. CONCLUSION SA-RS for total hysterectomy was possible, which is excellent in terms of cost, esthetics, and manpower.

Abstract
Koji is made by culturing koji mold on grains. Koji has wide-ranging applications, for example, in alcoholic beverages and seasonings. The word 'mold' generally has a bad image, but in Japan, koji mold is valued for its usefulness, and over the years, efforts have been made to make safe, stable, and delicious food products from it. Koji mold spores, essential when making koji, are called koji starter in the industry. From the many available strains, those suitable for the production of each fermented food are chosen based on indicators such as growth rate and enzyme production capacity. In manufacturing using microorganisms, purity and yield are prioritized. However, the production of fermented foods using koji is more complex, with focus not only on the degree of decomposition of raw materials but also on factors influencing overall product design, including palatability, color, smell, and texture. Production can be facilitated by the variety of koji brought about by the diversity of koji mold combined with the solid culture method which increases the amount of enzyme production. In this report, we introduce the history of koji starter in Japan, the characteristics of koji mold in practice, and various fermented foods made from it. In addition, the factors affecting the quality of koji in solid culture are described.

Abstract
Background:The alternative pathway of complement activation has recently been recognized as a key pathogenic event in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Some previous studies have reported that low serum complement C3 level in AAV patients is associated with more severe renal disease, worse renal prognosis, or higher mortality. However, the correlation between low serum C3 level and AAV relapse remains unclear.Objectives:To analyze the clinical characteristics and outcomes of AAV patients with low serum C3 levels at the time of diagnosis.Methods:We conducted a retrospective observational cohort study including 83 consecutive patients diagnosed with AAV in our hospital from January 1999 to December 2020. Serum C3 levels were measured at diagnosis. AAV included microscopic polyangiitis (MPA), granulomatosis with polyangiitis (GPA), and eosinophilic granulomatosis with polyangiitis (EGPA); patients with ANCA-negative AAV were excluded. Patients were divided into low- and high-C3 groups (C3 < 100 and ≥ 100 mg/dL, respectively). We compared the clinical characteristics, and relapse-free and overall survival rates, of the two groups, and identified predictors of AAV relapse.Results:Of the 83 patients (MPA, n = 61; GPA, n = 18; EGPA, n = 4), 20 (24%) were in the low-C3 group. We found no significant group difference in sex, body mass index, disease type, ANCA subtype, Birmingham Vasculitis Activity Score (BVAS), or treatment. The low-C3 group patients were older (p=0.01), and had a higher Five Factor Score (FFS) (p=0.01) and a lower remission rate (p=0.02), than the high-C3 group. The generalized Wilcoxon test revealed that the relapse-free survival time was significantly shorter in the low-C3 group (29 months; 95% confidence interval [CI]: 15–49) than in the high-C3 group (82 months; 95% CI: 61–NA; p=0.01) (Figure 1A). The overall survival was also shorter in the low-C3 group (83 months; 95% CI: 8-121) than in the high-C3 group (112 months; 95% CI: 77-NA; p=0.03) (Figure 1B). In the Cox proportional hazards model, a low C3 level (< 100 mg/dL) (hazard ratio [HR], 3.01; 95% CI: 1.29–7.04], p=0.01) and GPA (HR, 3.04; 95% CI: 1.32–7.01; p=0.01) were independent predictors of AAV relapse.Figure 1.Kaplan-Meier estimates of the relapse-free (A) and overall (B) survival rates of AAV patients by baseline serum C3 levels. Eight patients who did not show remission were excluded in the relapse-free survival analysis. Black line: high-C3 group (≥ 100 mg/dL); red line: low-C3 group (< 100 mg/dL).Conclusion:AAV patients with low C3 levels at diagnosis were at higher risk of relapse. Larger prospective studies are required to confirm these findings.Disclosure of Interests:None declared

Abstract
Shrimp is one of the most delicious and popular food commodities worldwide due to its exceptional taste and characteristics. Freshness is considered as a key factor for shrimp consumers because freshness has a significant relationship with taste and shelf-life of shrimp. However, post-mortem metabolism of shrimp differs from that of fish as they are highly susceptible to post-harvest quality loss, and it is hard to distinguish the freshness variation of shrimp at frozen state instantly. Thus, instant monitoring of frozen shrimp freshness is challenging for the seafood and aquaculture industries and a reliable, expeditious, and noninvasive technique to estimate shrimp quality is in high demand. Accordingly, this study aimed to visualize changes in post-mortem freshness of frozen shrimp using multidimensional fluorescence imaging. Live coonstripe shrimp (Pandalus hypsinotus) were harvested and instantly killed by beheading, cooled on ice for 0, 6, 24, 48, 72 and 96 h (n = 8), followed by processing into frozen peeled deveined shrimp product and stored at -60 °C. 50% of frozen shrimp were analyzed for excitation-emission matrix (EEM), ATP-related compounds, and pH using a fiber optic supported fluorescence spectrophotometer (F-7100), high performance liquid chromatography (HPLC) and pH meter, respectively at each time point (n = 4). Then, fluorescence images were obtained from the remaining 50% of frozen shrimp (n = 4) by computer vision method equipped with a charge-coupled device (CCD) camera, MAX-303 xenon light source for an excitation light (Ex. 330 nm), and an automatic filter changer for emission band-pass filters (Em. 380-610 nm at 10 nm intervals). Chemical analysis of frozen shrimp revealed that K-value and pH of shrimp increased from 1.61 to 66.56% and 6.49-7.31, respectively, during storage on ice. Repeated partial least squares regression (PLSR) models of EEM for K-value prediction suggested an efficient excitation wavelength (330 nm) and its corresponding emission wavelengths (380-610 nm) to produce fluorescence images. Spatial-temporal changes of K-value and pH were visualized successfully in frozen shrimp by fluorescence imaging. K-value visualization was then validated effectively using another group of frozen shrimp (0-72 h ice stored) with different killing method (super chilling) and the prediction accuracy was R2 = 0.80. This novel approach using a CCD camera coupled with EEM provides a state-of-the-art authentication method for practical assessment of frozen seafood freshness.

Abstract
INTRODUCTION Clinicopathological features of neuroendocrine differentiation of prostate carcinoma have not been totally clarified yet. It is known to be associated with poor prognosis. CASE PRESENTATION A patient with growing prostate-specific antigen was diagnosed with prostate carcinoma and treated by laparoscopic prostatectomy. The pathological examination revealed the neuroendocrine differentiation of the tumor. Early detection of prostate carcinoma with neuroendocrine differentiation can be difficult due to its low expression of prostate-specific antigen. The imaging examination contributed to the early detection. In the follow-up period of 2 years, the patient remains cancer free. CONCLUSION Recently, the treatment options for prostate carcinoma have been expanded. Precise assessment of immunohistochemical nature of the tumor may be helpful for individualized decision-making.

Abstract
Background:Among collagen vascular diseases, rheumatoid arthritis-associated interstitial lung disease (RA-ILD) is the most commonly associated with ILD with acute exacerbation (AE) [1]. One study reported that ILD diagnosis at an older age, the usual interstitial pneumonia (UIP) pattern on high-resolution computed tomography, and methotrexate (MTX) use were associated with AE in patients with RA-ILD [2]. However, because these studies included few patients, the risk factors and prognosis of AE in patients with RA-ILD remain unclear. Therefore, this study examined the characteristics of RA-ILD patients with AE, and the variables associated with mortality due to AE of RA-ILD.Objectives:To investigate the risk factors for AE and mortality of RA-ILD.Methods:We retrospectively collected the clinical data of 165 RA-ILD patients admitted to our hospital between July 2010 and October 2019. We compared clinical characteristics between patients who developed AE (AE group) and those who did not (non-AE group), and identified the variables significantly associated with AE occurrence. We also compared the admission characteristics of those who survived (survivor group) and those who died (non-survivor group) after admission for AE. AE was defined using previously proposed criteria [3], which were modified slightly for application to RA-ILD.Results:The mean patient age was 73.6 ± 9.7 years and 97 (71.9%) patients were female. Thirty (22.2%) patients developed AE, of whom thirteen (43.3%) died (mean follow-up, 64.9 months). In univariate analyses UIP pattern and MTX were not associated with AE. However, in multivariate analyses, UIP pattern was associated with AE (OR 2.68, 95% CI 1.10–6.52,p=0.03). Median age (70vs. 80 years,p=0.003), non-use of MTX (70.6%vs. 23.1%,p=0.025), and C reactive protein level (median 9.38vs. 18.12 mg/dL,p=0.02) on admission were significantly higher in patients who died of AE. In the Cox proportional hazard model, UIP pattern (HR 4.67, 95% CI 1.02–21.5,p=0.048) and non-use of MTX (HR 0.16, 95% CI 0.04–0.72,p=0.016) were associated with death.Conclusion:Our data suggest that the UIP pattern is related to AE, and non-use of MTX and UIP pattern are related to death due to AE of RA-ILD.References:[1] Suda T, Kaida Y, Nakamura Y et al.

Abstract
Because ofboth the indolent and aggressive nature ofprostate cancers, it is not easy to select the best treatment for patients receiving home medical care who already have many diseases. Since the growth ofprostate cancer is generally slow and all treatments adversely affect the quality of life to some degree, conservative treatment may well be the best option for these patients with prostate cancer. However, it is also true that we often encounter home medical care patients with a locally advanced cancer who had symptoms such as difficulty to urine, macrohematuria and/or lumbago. Such patients need to be diagnosed soon and treated with mainly hormonal therapy after consultation with the specialist. Thus, after a careful evaluation ofthe nature ofthe cancer and comorbidity, we need to provide the best option ofdiagnosis and treatment for home medical care patients to maintain their quality of life.

Abstract
Transposable element (TE) marker system was developed considering the useful properties of the transposable elements such as their large number in the animal and plant genomes, high rate of insertion polymorphism, and ease of detection. Various methods have been employed for developing a large number of TE markers in several crop plants for genomics studies. Here we describe some of these methods including the recent whole genome search. We also review the application of TE markers in molecular breeding.

Abstract
Objective The objective of this study was to investigate possible differences in
treatment responses between two categories for the onset of lupus
nephritis. Methods We performed a multicentre, retrospective cohort study of class III–V lupus
nephritis patients diagnosed between 1997 and 2014. The renal responses to
initial induction therapy were compared between patients who developed lupus
nephritis within one year from diagnosis of systemic lupus erythematosus
(early (E-) LN) and the remainder (delayed (D-) LN) using the Kaplan–Meier
method. We determined the predictors of renal response as well as renal
flares and long-term renal outcomes using multivariate Cox regression
analyses. Results A total of 107 E-LN and 70 D-LN patients were followed up for a median of
10.2 years. Log-rank tests showed a lower cumulative incidence of complete
response in D-LN compared with E-LN patients. Multivariate analysis
identified D-LN (hazard ratio (HR) 0.48, 95% confidence interval (CI)
0.33–0.70), nephrotic syndrome at baseline, and a chronicity index greater
than 2 as negative predictors of complete response. D-LN patients were more
likely to experience renal flares. D-LN (HR 2.54, 95% CI 1.10–5.83) and
decreased renal function were significant predictors of chronic kidney
disease at baseline. Conclusion D-LN was a predictor of poorer treatment outcomes, in addition to renal
histology and severity of nephritis at lupus nephritis onset.

Abstract
Salvage esophagectomy (SALV) is potentially beneficial for patients with residual or relapsed esophageal carcinoma after definitive chemoradiotherapy (dCRT), although preoperatively identifying good candidates for SALV remains difficult. We investigated the prognostic impacts of inflammatory and nutritional status in patients undergoing SALV after dCRT. Forty-seven SALV patients were retrospectively reviewed, of whom 46 (98%) had squamous cell carcinoma and 1 (2%) adenocarcinoma. Possible prognostic factors included patients' demographic data, physical status, blood chemistry profiles, and clinical/pathological tumor features. The Glasgow prognostic score (GPS) was derived from preoperative C-reactive protein (CRP) and albumin values. Thirty (64%), 11 (23%), and 6 (13%) patients were classified into the GPS 0, 1, and 2, respectively, groups. None of the possible prognostic factors showed significant correlations with GPS. Patients with GPS 0 had better outcomes than those with GPS 1 or GPS 2 (Median survivals: 37.8, 15.9, and 5.1 months, respectively, P < 0.001). In the multivariable Cox proportional hazards model, GPS 1 (HR 5.62, 95% CI 1.94-16.4, P = 0.002), GPS 2 (HR 9.10, 95% CI 2.60-31.8, P < 0.001), R1/2 resection (HR 16.3, 95% CI 3.62-86.7, P < 0.001) and incomplete response to dCRT (HR 3.53, 95% CI 1.12-12.5, P = 0.03) were all independent risk factors for a poor outcome. Preoperative GPS is potentially useful for predicting outcomes in esophageal cancer patients undergoing SALV.

Abstract
Objective: Several prognostic factors for biochemical recurrence after radical prostatectomy have been reported, including initial prostate-specific antigen level, Gleason score, positive surgical margin, and seminal vesicle invasion. Here we investigate whether Gleason pattern 5 is a predictor for biochemical recurrence. Methods: This retrospective study included 168 patients who underwent laparoscopic radical prostatectomy from 2006 to 2015. The relationship between biochemical recurrence after laparoscopic radical prostatectomy and the presence of Gleason pattern 5, even as a tertiary pattern, was investigated. Biochemical recurrence was defined when the prostate-specific antigen level rose to >0.2 ng/ml after having decreased to <0.1 ng/ml following laparoscopic radical prostatectomy. Biochemical recurrence-free survival was estimated by the Kaplan-Meier method. Multivariate analysis was performed using a Cox proportional hazards regression model. Results: The median age was 66 years, median initial prostate-specific antigen level was 6.9 ng/ml, and median follow-up period was 47.3 months. Biochemical recurrence was recognized in 27 patients (16.1%) after laparoscopic radical prostatectomy, and 5-year biochemical recurrence-free survival was 78.6%. Gleason pattern 5 was noted in 5 patients as the primary pattern, in 10 as the secondary pattern, and in 5 as the tertiary pattern. According to multivariate analysis, presence of Gleason pattern 5 (HR = 4.75, p=0.001) and positive surgical margin (HR = 4.66, p=0.001) were independent predictive factors for biochemical recurrence-free survival. Conclusion: Gleason pattern 5 appears to be an important predictive factor for biochemical recurrence after laparoscopic radical prostatectomy.

Abstract
No study has systematically reviewed the evidence on presentation of oropharyngeal dysphagia and swallowing rehabilitation following esophagectomy. The purposes of this systematic review are to 1) qualitatively synthesize the current findings on oropharyngeal swallowing abnormalities identified by instrumental swallowing evaluations, 2) describe the reported health-related outcomes in relation to swallowing abnormality following esophagectomy, and 3) examine the efficacy of reported rehabilitative interventions for oropharyngeal dysphagia in patients who underwent esophagectomy. Publications were searched using five electronic databases. No language or publication date restrictions were imposed. Two authors performed a blind review for published or unpublished studies that reported swallowing biomechanics and dysphagic symptoms using instrumental evaluation of swallowing, specifically the videofluoroscopic swallowing study and fiberoptic endoscopic evaluation of swallowing, and/or health-related outcomes in relation to swallowing abnormalities, and/or therapeutic interventions for oropharyngeal dysphagia following esophagectomy. Twelve studies out of 2,193 studies including 458 patients met the inclusion criteria. Reported abnormal swallowing biomechanics included vocal fold immobility, delayed onset of swallowing, reduced hyolaryngeal elevation, and reduced opening of the upper esophageal sphincter. Aspiration (0-81%) and pharyngeal residue (22-100%) were prevalent. Those abnormal swallowing biomechanics and swallowing symptoms were commonly reported following both transhiatal and transthoracic esophagectomy. Pneumonia presented in 5-25% of the study patients. One quasi-experimental study examined the effectiveness of swallowing exercises for postoperative oropharyngeal dysphagia; three case series reported a benefit of the chin-tuck maneuver in reducing aspiration and residue. This review revealed distinct swallowing impairments and increased pneumonia risks following esophagectomy. This review also found that evidence on the efficacy of therapeutic interventions was limited. Future studies are warranted to develop effective rehabilitative interventions for postesophagectomy patients with oropharyngeal dysphagia.

Abstract
BACKGROUND Cognitive-behavioral therapy (CBT) is thought to be useful for chronic pain, with the pathology of the latter being closely associated with cognitive-emotional components. However, there are few resting-state functional magnetic resonance imaging (R-fMRI) studies. We used the independent component analysis method to examine neural changes after CBT and to assess whether brain regions predict treatment response. METHODS We performed R-fMRI on a group of 29 chronic pain (somatoform pain disorder) patients and 30 age-matched healthy controls (T1). Patients were enrolled in a weekly 12-session group CBT (T2). We assessed selected regions of interest that exhibited differences in intrinsic connectivity network (ICN) connectivity strength between the patients and controls at T1, and compared T1 and T2. We also examined the correlations between treatment effects and rs-fMRI data. RESULTS Abnormal ICN connectivity of the orbitofrontal cortex (OFC) and inferior parietal lobule within the dorsal attention network (DAN) and of the paracentral lobule within the sensorimotor network in patients with chronic pain normalized after CBT. Higher ICN connectivity strength in the OFC indicated greater improvements in pain intensity. Furthermore, ICN connectivity strength in the dorsal posterior cingulate cortex (PCC) within the DAN at T1 was negatively correlated with CBT-related clinical improvements. CONCLUSIONS We conclude that the OFC is crucial for CBT-related improvement of pain intensity, and that the dorsal PCC activation at pretreatment also plays an important role in improvement of clinical symptoms via CBT.

Abstract
Abstract
Background: E17K is the most common activating AKT1 mutation and was shown to be a therapeutic target in this multipart Phase 1 study of AZD5363 (NCT01226316), an oral and selective pan-AKT kinase inhibitor, in patients (pts) with AKT1-mutant (AKT1m) advanced solid tumors. In heavily pretreated AKT1m (E17K) ER+ metastatic breast cancer (MBC) pts, monotherapy achieved an objective response rate (ORR) of 20% and a median progression-free survival of 5.5 months (95% CI, 2.9−6.9). Suppression of PI3K-AKT signaling results in induction of ER-dependent transcription, potentially limiting the response to single-agent PI3K/AKT inhibitors. We explored the hypothesis that simultaneous inhibition of AKT and ER signaling would enhance antitumor efficacy in AKT1m ER+ MBC.
Methods: In an expansion of this study, we administered oral AZD5363 400 mg twice daily, 4 days on 3 days off, and fulvestrant 500 mg, to AKT1m (detected in tumor tissue by local screening and/or plasma BEAMing) ER+ HER2– MBC pts, enrolled into a fulvestrant-naïve (FN) or fulvestrant-resistant (FR) cohort (max 24 pts/cohort). Key objectives included safety and efficacy by RECIST v1.1. We report results of a planned interim analysis conducted when 12 pts/cohort reached maturity for assessment of 24-week clinical benefit rate (CBR), defined as the percentage of responders plus those with stable disease (SD) ≥24 weeks.Data cut-off occurred in June 2017.
Results: At the time of analysis, 24 AKT1m pts (23 E17K, 1 E40K) had received treatment. FN had more visceral disease (83.3% vs 66.7%) and ER+/PR– status (25% vs 8.3%) than FR. Median number of prior anticancer regimens was 4.5 (range 1–9) and 6 (2–11) in FN and FR, respectively, with more chemotherapy (CT) and less hormone therapy (HT) exposure in FN vs FR [3 (0–5) vs 2 (0–6) and 2 (0–4) vs 4 (2–6) prior CT and HT, respectively]. Prior palbociclib was received by 1 (8.3%) and 4 (33.3%) pts in FN and FR, respectively. Clinical efficacy is detailed below; CBR was 33% and 42% in FN and FR, respectively (Table 1). There was 1 unconfirmed partial response in patients treated with prior palbociclib and 3 SD. At data cut-off, 18 pts had discontinued treatment: progressive disease, n=12; adverse events (AEs), n=2; other reasons, n=4. AEs were observed in all 24 pts, most commonly diarrhea (71%), nausea (63%), vomiting and decreased appetite (29%). Grade ≥3 AEs occurred in 13 (54%) pts, most frequently maculopapular rash (n=3), nausea, hyperglycemia and back pain (all n=2). Dose reduction due to AEs occurred in 3 pts.

Conclusions: AZD5363 plus fulvestrant is clinically active in AKT1m ER+ MBC pts, including in pts with demonstrated prior resistance to fulvestrant. Comparatively lower efficacy was observed in the FN cohort; factors that may have potentially contributed (eg disease characteristics) will be explored. cfDNA and genomic data will also be presented.

Abstract
Abstract
Background: Endocrine therapy is the most important treatment option for women with estrogen receptor (ER)-positive breast cancer. We recently reported that approximately two-thirds of patients who relapsed within 5 years had received anthracyclins and/or taxanes as adjuvant or neoadjuvant chemotherapy in addition to adjuvant endocrine therapy. New strategies, such as signal transduction inhibitors together with endocrine therapy are required to improve survival. PIK3CA mutations are detected in almost 40% of early ER-positive breast cancers, and are therefore the most frequent genetic alterations in this subtype. PIK3CA mutation status is reported to affect activation of AKT and ERα. Moreover, recent studies demonstrate that patients had a better prognosis when tumors expressed ER, androgen receptor (AR), and vitamin D receptor (VDR).
Methods: Expression of AR and VDR, phosphorylation of AKT serine (Ser) 473 (AKT phospho-Ser473) and ERα Ser167 (ERα phospho-Ser167) were examined by immunohistochemistry in ER-positive, HER2-negative early breast cancer tissues. Seventeen mutations in exons 1, 4, 7, 9, and 20 of the PIK3CA gene were detected in genomic DNA extracted from formalin-fixed paraffin-embedded tumor blocks. Correlations between these biological markers and clinicopathological factors and prognosis were analyzed separately in pre- and postmenopausal women.
Results: Levels of AKT phospho-Ser473 were significantly higher in premenopausal women (n = 62) than in postmenopausal women (n = 152) (P < 0.0001 and P = 0.014, respectively). In contrast, expression levels of AR were significantly higher in postmenopausal women than in premenopausal women (P < 0.0001). In premenopausal women, 26 tumors (43%) had a single mutation of PIK3CA gene, and 3 tumors (5%) had mutations at two sites. In postmenopausal women, 64 tumors (44%) had a single PIK3CA mutation, 6 tumors (4%) had mutations at two sites, and one tumor (1%) had mutations at three sites. In premenopausal women, wild type PIK3CA was associated with smaller tumor size, higher ER expression levels, and lower AR expression levels when compared with women in the same cohort with PIK3CA mutant tumors. In postmenopausal women, patients with PIK3CA wild-type tumors had higher Ki67 labeling index, higher AKT phospho-Ser473, and lower ERα phospho-Ser167 when compared to patients with PIK3CA mutant tumors. Postmenopausal women with PIK3CA wild-type tumors had significantly worse disease-free survival than patients with PIK3CA mutant tumors (P = 0.007). In contrast, PIK3CA mutation status was not correlated with survival in premenopausal women. Low levels of AKT phospho-Ser473 and high levels of ERα phospho-Ser167 were strongly associated with increased disease-free survival in postmenopausal women (P = 0.016 and P = 0.0016, respectively).
Conclusion: ERα activation, in addition to PIK3CA mutation, may be biomarkers for highly endocrine-responsive tumors. This would facilitate the selection of postmenopausal ER-positive breast cancer patients who are likely to benefit from endocrine therapy alone from those who are not.

Abstract
BACKGROUND Reducing the urinary sodium-to-potassium ratio is important for reducing both blood pressure and risk of cardiovascular disease. Among free-living Japanese individuals, we carried out a randomized trial to clarify the effect of lifestyle modification for lowering urinary sodium-to-potassium ratio using a self-monitoring device. METHODS This was an open, prospective, parallel randomized, controlled trial. Ninety-two individuals were recruited from Japanese volunteers. Participants were randomly allocated into intervention and control groups. A month-long dietary intervention on self-monitoring urinary sodium-to-potassium ratio was carried out using monitors (HEU-001F, OMRON Healthcare Co., Ltd., Kyoto, Japan). All participants had brief dietary education and received a leaflet as usual care. Monitors were handed out to the intervention group, but not to the control group. The intervention group was asked to measure at least one spot urine sodium-to-potassium ratio daily, and advised to lower their sodium-to-potassium ratio toward the target of less than 1. Outcomes included changes in 24-hour urinary sodium-to-potassium ratio, sodium excretion, potassium excretion, blood pressure, and body weight in both groups. RESULTS Mean measurement frequency of monitoring was 2.8 times/day during the intervention. Changes in urinary sodium-to-potassium ratio were -0.55 in the intervention group and -0.06 in the control group (P = 0.088); respective sodium excretion changes were -18.5 mmol/24 hours and -8.7 mmol/24 hours (P = 0.528); and corresponding potassium excretion was 2.6 mmol/24 hours and -1.5 mmol/24 hours (P = 0.300). No significant reductions were observed in either blood pressure or body weight after the intervention. CONCLUSIONS Providing the device to self-monitor a sodium-to-potassium ratio did not achieve the targeted reduction of the ratio in "pure self-management" settings, indicating further needs to study an effective method to enhance the synergetic effect of dietary programs and self-monitoring practice to achieve the reduction. However, we cannot deny the possibility of reducing sodium-to-potassium ratio using a self-monitoring device.
