Disproportionate cancer worries in ultra-short-segment Barrett's esophagus in Japan. DEN OPEN 2024; 4:e329. [PMID: 38223912 PMCID: PMC10787273 DOI: 10.1002/deo2.329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 12/14/2023] [Accepted: 12/18/2023] [Indexed: 01/16/2024]
Abstract
Objectives Although Barrett's esophagus (BE), especially ultra-short-segment BE (USSBE), is very frequently diagnosed in Japan, how subjects feel about receiving a diagnosis of BE is unclear. We therefore prospectively investigated cancer worry in subjects who received a BE diagnosis. Methods Self-administered questionnaires were sent to subjects who were diagnosed with BE at three health checkup institutes in Akita Prefecture, Japan. The cancer worry scale (CWS) was used to quantitatively assess the fear of developing cancer. The BE subjects were classified into USSBE <1 cm and non-USSBE ≥1 cm groups. Factors associated with the CWS were investigated using logistic regression analyses. Results A total of 325 (31%) subjects, comprising 229 USSBE and 96 non-USSBE patients were included in this study. Compared with the USSBE group, the non-USSBE group had a significantly higher frequency of a history of a BE diagnosis and perception of carcinogenesis. However, the CWS was similar between the USSBE and non-USSBE groups, with a median CWS of 12.5 (3.75) versus 12.7 (3.65). A multivariate logistic regression analysis revealed that while positive reflux symptoms were significantly associated with a positive CWS, the BE length was not significantly associated with it, with an odds ratio (95% confidence interval) of 1.3 (0.75-2.2). Conclusions A BE diagnosis promotes a similar level of worry about cancer among subjects, irrespective of the length of BE. In Japan, since USSBE poses a much lower cancer risk than non-USSBE, the former may frequently be associated with a disproportionate cancer worry relative to the latter. (UMIN000044010).

Helicobacter pylori Eradication Does Not Adversely Affect the Clinical Course of Gastric Cancer: A Multicenter Study on Screening Endoscopic Examination in Japan. Cancers (Basel) 2024; 16:733. [PMID: 38398125 PMCID: PMC10887210 DOI: 10.3390/cancers16040733] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Revised: 02/04/2024] [Accepted: 02/08/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND Since gastric cancers (GCs) detected after Helicobacter pylori (HP) eradication present with different morphological characteristics from conventional HP-positive GCs, delayed detection of early-stage GCs may be observed. This study aimed to investigate the clinical impact of HP eradication on diagnosing GC during screening endoscopy. METHODS Eleven health checkup institutions in Japan participated in the present study. All GC cases newly diagnosed by screening endoscopy between January 2016 and December 2020 were included. After propensity score matching, multivariable regression analysis was performed to estimate the effect of HP eradication on deep tumor invasion among HP-eradicated and HP-positive GC cases. RESULTS A total of 231 patients with GCs (134 HP-eradicated and 97 HP-positive cases) were enrolled. After propensity score matching, there were 81 cases in each group. The distribution of the depth of tumor invasion (pT1a, pT1b1, pT1b2, and pT2) between the HP-eradicated group and HP-positive group was similar (p = 0.82). In the propensity analysis, with HP-positive as the reference value, HP eradication was not significantly associated with T1b-T4-GCs and T1b2-T4-GCs, with odds ratios (95% confidence intervals) of 1.16 (0.48-2.81) and 1.16 (0.42-3.19), respectively. CONCLUSIONS HP eradication does not adversely affect the clinical course of GCs, supporting the recommendation of HP eradication in screening programs to reduce the total number of GC cases without delaying diagnosis.

Abstract
OBJECTS Ultrashort-segment Barrett's esophagus (USSBE; length of <1 cm) is very frequently diagnosed in Japan, but the cancer risk of USSBE is unknown. In this study, by retrieving endoscopic images, we retrospectively investigated the incidence of esophageal adenocarcinoma (EAC) by the grade of Barrett's esophagus (BE) and compared the findings with those of gastric cancer by the degree of endoscopic gastric atrophy in the same population. METHODS Among consecutive participants who had undergone endoscopy for an annual health checkup in 2014, the 9121 who had received at least one follow-up endoscopy by December 2020 were enrolled in this study. Using the retrieved endoscopic images, we retrospectively evaluated BE and gastric atrophy. Information on the subsequent occurrence of EAC and gastric cancer as of December 2020 was also collected. The incidence of cancer by the extent of BE and gastric atrophy was calculated and expressed as the percentage per year. RESULTS On reviewing the endoscopic image in 2014, 4190 (45.9%) were found to have been diagnosed with BE, of whom 3318 (36.4%) were judged to have USSBE. During an observation period of 54.1 (17.9) months, 89 gastric cancers and only two EACs were identified. The incidence of EAC in USSBE was 0.0068%/year, which was nearly as low as the incidence of gastric cancer in atrophy-free patients (0.0068% vs. 0.0059%/year). CONCLUSIONS Although the prevalence of USSBE is quite high (36.4%), the incidence of EAC in USSBE is very low (0.0068%/year). Accordingly, USSBE can be excluded from targets for endoscopic surveillance in Japan.

Abstract
Abstract
Background
Mutations in phosphatidylinositol 3-kinase (PI3K), which encodes the catalytic subunit of PI3Kα, is one of the most frequent genomic alterations and is found in about 40% of estrogen receptor (ER)-positive, HER2 negative breast cancers. PIK3CA mutations promote the growth and proliferation of cancers via activation of the PI3K/mammalian target of rapamycin pathway and can mediate resistance to endocrine therapies in breast cancer. Although several clinical trials for PI3K inhibitors (PI3Kis) in ER-positive metastatic breast cancers are ongoing, the effects of PI3Kis on endocrine-resistant breast cancers with various characteristics and definitive biomarkers of PI3Kis are unclear. Using endocrine-resistant cells established in our laboratory, we evaluated the efficacy of PI3Ki in these cell lines and identified the characteristics associated with acquired resistance to PI3Kis in endocrine-resistant cells.
Results
Long-term estrogen deprivation-resistant (EDR) cell lines and fulvestrant-resistant cell lines (MFR and TFR) were established from MCF-7 and T-47D cells in our previous studies. These cell lines showed different ER expression levels, including high expression (EDR-1), low expression (EDR-2, -3), or no expression (MFR, TFR); all of these cell lines had the same PIK3CA mutations as the parental cell lines. The pan-class1 PI3Ki buparlisib (BKM120) and α-specific PI3K inhibitor alpelisib (BYL719) inhibited the proliferation of endocrine-resistant cell lines when compared with their parental cells. Among endocrine-resistant cells, MFR cells were dramatically inhibited by PI3Kis. Colony formation assays indicated that MFR cells were more sensitive to PI3Kis than other cells lines. Next, we established PI3Ki- and everolimus-resistant cell lines from EDR-1, EDR-2, and MFR cells using BKM120, BYL719, and everolimus. Analysis of the time required to generate resistant cells showed that MFR cells required twice as long to acquire resistance compared with EDR cells. Furthermore, the time required to acquire resistance to BYL719 was shorter than that for BKM120. BYL719-resistant (BYL-R) cells were effectively inhibited by BKM120 to a degree similar to that of parental cells; however, BYL-R cells lost sensitivity to BYL719 and everolimus. Evelolimus-resistant (EVE-R) cells were also the same. In contrast, BKM120-resistant (BKM-R) cells showed less sensitivity to BKM120, BYL719, and everolimus. In other words, the pan-PI3Ki BKM120 was able to inhibit the growth of BYL-R and EVE-R cells, whereas BYL719 and everolimus were not able to inhibit BKM-R cells sufficiently. In addition, there were no changes in ER expression in EDR-1, EDR-2, and MFR cells exposed to PI3Kis for 1 h. Interestingly, ER expression on EDR-2 cells with acquired resistance to PI3Kis was increased compared with that in parental cells.
Conclusion
Our findings showed that PI3Kis exhibited remarkable efficacy in all types of EDR cells, particularly in fulvestrant-resistant cell lines. In PI3Ki- and everolimus-resistant cell lines, BKM120 and BYL719 showed different effects, and BYL719 and everolimus may exhibit cross-resistance. Furthermore, PI3Kis were likely to change the expression of ER.

Abstract
Canine mammary tumours (CMTs) are the most common neoplasms affecting female dogs. There is an urgent need for molecular biomarkers that can detect early stages of the disease in order to improve accuracy of CMT diagnosis. The aim of this study was to examine whether caveolin-1 (Cav-1) and matrix metalloproteinase 14 (MMP14) are associated with CMT histological malignancy and invasion. Sixty-five benign and malignant CMT samples and six normal canine mammary glands were analysed using quantitative reverse transcription-polymerase chain reaction. Cav-1 and MMP14 genes were highly expressed in CMT tissues compared to normal tissues. Cav-1 especially was overexpressed in malignant and invasive CMT tissues. When a CMT cell line was cultured on fluorescent gelatin-coated coverslips, localisation of Cav-1 was observed at invadopodia-mediated degradation sites of the gelatin matrix. These findings suggest that Cav-1 may be involved in CMT invasion and that the markers may be useful for estimating CMT malignancy.

Abstract
The implementation of genomic selection for Japanese Black cattle, known for rich marbling of their meat, is now being explored. Although multiple-step methods are often adopted for dairy cattle, they present shortcomings such as bias and loss of information in addition to operational complexity. These can be avoided using single-step genomic BLUP (ssGBLUP) based on the relationship matrix H, which is constructed from the numerator relationship matrix (A) augmented by the genomic relationship matrix (G). This study assessed the use of ssGBLUP for 3 economically important traits in Japanese Black cattle. Three aspects of ssGBLUP that are important for practical use were examined specifically: the mixing proportions of blending G with A, selection of subsets of genotyped animals used for constructing H, and prediction ability for ungenotyped animals. Different mixing proportions were tested to assess the influence of these proportions on variance component estimation and prediction accuracy. For all traits, the highest or nearly highest accuracy was obtained when the adopted mixing proportion provided heritability closest to that inferred based on A. However, the accuracy did not increase greatly under adjustment of the mixing proportion, thereby suggesting that the influence of the mixing proportion on the accuracy was limited. Genotype data of influential bulls showed a greater contribution to accuracy than that of bulls that were less influential. Genotyping animals with phenotypic records increased the accuracy. It can be prioritized over genotyping bulls that are not influential on the population. These results are expected to present good guides to the future expansion of genotyped populations. Even for animals without genotype data but with genotyped sires, ssGBLUP provided more accurate prediction than BLUP did. For both phenotype and breeding value prediction, ssGBLUP provides more accurate prediction than BLUP, suggesting its usefulness in genomic selection in Japanese Black cattle.

Abstract
BACKGROUND One of the problems of cadaveric renal transplantation is that its graft survival rate is less than that for living renal transplantation. We aim to study relationships between the graft survival of cadaveric renal transplantation patients and various factors. MATERIALS AND METHODS We retrospectively analyzed 350 cadaveric renal transplantation patients from our institutions from 1983 to 2011. Kaplan-Meier analysis was performed to evaluate graft survival ratios. Using a multivariable Cox regression model, we evaluated the relationship between graft survival and the factors such as age and gender of donor and recipient, body mass index of recipient, duration of hemodialysis, warm ischemic time, and acute rejection (AR), etc. RESULTS Among 235 males and 115 females, the overall mean age was 41 years. Median follow-up was 15 years (2 to 28 years). The graft survival ratio was 97% at 1 year, 85% at 5 years, and 71% at 10 years. Using the Cox regression model, graft survival was affected by donor age (younger than 60 years; hazard ratio [HR] 1.5; 95% confidence interval (CI) 1.0-2.0; P = .027) and early acute rejection (within 3 months; HR 2.1; CI 1.6-2.8; P < .001). CONCLUSIONS The graft survival of cadaveric renal transplantation patients is affected by factors of donor age and early AR.

Abstract
Dipeptidyl peptidase-4 (DPP-4) inhibitor is a new class of anti-diabetic drug which exerts its glucose-lowering action by suppressing the degradation of a gut incretin hormone glucagon-like peptide-1 (GLP-1). To elucidate whether treatment with stronger DPP-4 inhibitor on top of angiotensin II type 1 receptor blocker (ARB) provides greater renal protective effects, we performed a crossover study with two DPP-4 inhibitors, sitagliptin and alogliptin, in twelve type 2 diabetic patients with incipient nephropathy taking ARBs. This study consisted of three treatment periods: sitagliptin 50 mg/day for 4 weeks (first period), alogliptin 25 mg/day for 4 weeks (second period), and sitagliptin 50 mg/day for 4 weeks (third period). Significant changes in body mass index, blood pressure, serum lipids, serum creatinine, estimated glomerular filtration rate, and HbA1c were not observed among the three treatment periods. Reduced urinary levels of albumin and an oxidative stress marker 8-hydroxy-2'-deoxyguanosine (8-OHdG), increased urinary cAMP levels, and elevated plasma levels of stromal cell-derived factor-1α (SDF-1α) which is a physiological substrate of DPP-4 were observed after the switch from sitagliptin to a stronger DPP-4 inhibitor alogliptin. Given a large body of evidence indicating anti-oxidative action of cAMP and up-regulation of cellular cAMP production by SDF-1α, the present results suggest that more powerful DPP-4 inhibition on top of angiotensin II type 1 receptor blockade would offer additional protection against early-stage diabetic nephropathy beyond that attributed to glycemic control, via reduction of renal oxidative stress by SDF-1α-cAMP pathway activation.

Spatial distributions of floating seaweeds in the East China Sea from late winter to early spring. JOURNAL OF APPLIED PHYCOLOGY 2013; 26:1159-1167. [PMID: 24771973 PMCID: PMC3988520 DOI: 10.1007/s10811-013-0139-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/26/2013] [Revised: 08/25/2013] [Accepted: 08/26/2013] [Indexed: 05/12/2023]
Abstract
Floating seaweeds play an important role as a habitat for many animals accompanying or attaching to them in offshore waters. It was in 2000 that the first report described abundant distributions of floating seaweeds in offshore waters in the East China Sea in spring. Young individuals of the yellowtail Seriola quinqueradiata are captured for aquaculture purposes from floating seaweeds in the East China Sea. Therefore, a sound understanding of the distributions of floating seaweeds in the East China Sea is needed. Detailed information is especially important during the late winter to early spring, which corresponds to the juvenile period of the yellowtail. Thus, field surveys using R/V Tansei-Maru were conducted in the Japanese Exclusive Economic Zone in the East China Sea from late winter to early spring in 2010 and 2011. We obtained positions of the vessel by GPS and transversal distances from the vessel to a raft by visual observation. Distance sampling method (Thomas et al. 2010) was applied to estimation of floating seaweed densities (rafts km-2). Seaweed rafts were also randomly sampled using nets during the research cruises. In the East China Sea, seaweed rafts were distributed mainly on the continental shelf west of the Kuroshio, especially in waters between 26° N and 30° N. Collected rafts consisted of only one species, Sargassum horneri (Turner) C. Agardh. Taking into account surface currents and geographical distribution of S. horneri, it is estimated that these floating seaweeds originated from natural beds along the coast between mid and south China. Considering the approximate travel times, it is suggested that floating patches are colonized by yellowtails early on during their trips, i.e., close to the Chinese coast.

Abstract
The authors established apoptosis resistant COS-1, myeloma, hybridoma, and Friend leukemia cell lines by genetically engineering cells, aiming at more efficient protein production by cell culture. COS-1 cells, which are most widely used for eukariotic gene expression, were transfected with human bcl-2 gene. Both bcl-2 and mock transfected COS-1 cells were cultured at low (0.2%) serum concentration for 9 days. The final viable cell number of the bcl-2 transfected cells was ninefold of that of the mock transfectants. Both bcl-2 and mock transfectants were further transfected with the vector pcDNA-λ containing SV40 ori and immunoglobulin λ gene for transiently expressing λ protein. The bcl-2 expressing COS-1 cells produced more λ protein than the mock transfected COS-1 cells after 4 days posttransfection.Mouse myeloma p3-X63-Ag.8.653 cells, which are widely used as the partner for preparing hybridoma, and hybridoma 2E3 cells were transfected with human bcl-2 gene. Both bcl-2 transfected myeloma and hybridoma survived longer than the corresponding original cells in batch culture. The bcl-2 transfected 2E3 cells survived 2 to 4 four days longer in culture, producing 1.5- to 4-fold amount of antibody in comparison with the mock transfectants.Coexpression of bag-1 with bcl-2 improved survival of hybridoma 2E3 cells more than bcl-2 expression alone. The bag-1 and bcl-2 coexpressing cells produced more IgG than the the cells expressing bcl-2 alone.Apoptosis of Friend murine erythroleukemia(F-MEL) cells was suppressed with antisense c-jun expression. The antisense c-jun expressing cells survived 16 days at non-growth state.

Abstract
Human bcl-2 and bag-1 DNA were introduced into mouse hybridoma 2E3- O cells and expressed. The expression of bcl-2 in BCMGneo-bcl2 transfectants was confirmed by ELISA and that of bag-1 in pZeo-bag1 was confirmed by western blotting. In batch cultures, the over-expression of bcl-2 prolonged the culture period by 2 days and co-expression of bcl-2 and bag-1 prolonged the culture period by 3 days. The delayed increase in the dead cell number in culture of the bcl-2 and bag-1 cotransfectant indicated the additional antiapoptosis effect of bcl-2 and bag-1 cotransfection in comparison with the bcl-2 only transfection. The bcl-2 transfectants (2E3O-Bcl2) produced antibody twofold per batch culture in comparison with 2E3-O cells transfected with BCMGSneo (2E3O-Mock). Enhancement of this MoAb production was due to the improved survival of the cells and was not due to stimulation of antibody production rate per cell by Bcl-2 expression. And the bcl-2 and bag-1 co-transfectant (2E3O-Bcl2-BAG1) produced antibody approximately fourfold of 2E3O-Mock per batch culture. Enhancement of this MoAb production was due to the improved survival of the cells and was partly due to stimulation of MoAb production rate per cell in the non-growing phase by the cotransfection. The method to engineer hybridoma cells genetically with bcl-2 and bag-1 for increasing viability and productivity would be widely applied for improving antibody productivity of hybridoma cultures.

Abstract
A 79-year-old female who had been observed for an intrapericardial cyst for 3 years was admitted due to severe dyspnea and back pain. During 3 years observation, there were no symptoms and no growth of the cyst. Computed tomography scans showed rapid expansion of the cyst compared with an magnetic resonance imaging (MRI) taken 9-days before when she visited our hospital for the 1st time. Urgent complete extirpation of the tumor was successfully done and a histological diagnosis found it was an intrapericardial bronchogenic cyst. This is a 1st report of intrapericardial bronchogenic cyst of which rapid expansion is clearly demonstrated by radiology. It is suggested that complete surgical excision of intrapericardial bronchogenic cysts at the time of diagnosis even if asymptomatic.

Abstract
BACKGROUND AND STUDY AIMS Carbon dioxide (CO (2)) insufflation for endoscopy has been reported to provide superior recovery and is expected to reduce the risk of serious complications, including air embolism and tension pneumothorax, whereas general anesthesia offers some advantages not found under intravenous sedation. Little is known about the effect of prolonged CO (2) insufflation into gastrointestinal tracts on arterial CO (2) tension (PaCO (2)). Here we introduce the use of general anesthesia with CO (2) insufflation for esophagogastroduodenal endoscopic submucosal dissection (ESD). PATIENTS AND METHODS A prospective observational study was conducted in a university-affiliated hospital. A total of 100 patients were scheduled for esophagogastroduodenal ESD under general anesthesia with CO (2) insufflation, using standardized anesthesia techniques and unchanged ventilatory settings. Arterial blood gas analyses were repeated at predetermined time intervals. RESULTS Of the initial 100 participants, 94 patients undergoing ESD and four patients undergoing endoscopic mucosal resection completed the study. The median procedure time was 122 minutes (range 29 - 309 minutes). The median baseline PaCO (2) of 28 mmHg increased to a median peak PaCO (2) of 39 mmHg ( P < 0.001), with marked inter-individual variability in the time courses of changes in PaCO (2). The correlation coefficient of PaCO (2) with the procedure time was low (r = 0.194; n = 577, P < 0.0001). FEV (1.0) % (forced expiratory volume in 1 second/forced vital capacity) of < 70 % and esophagoscopy vs. gastroduodenoscopy were relative enhancement factors of PaCO (2). CONCLUSION Increases of PaCO (2) during esophagogastroduodenal ESD under general anesthesia with CO (2) insufflation remained within acceptable or readily controllable ranges, and are little enhanced by prolongation of the procedure. Esophagogastroduodenal ESD can be performed safely and feasibly with this procedure.
