Precise application of topical tranexamic acid to enhance endoscopic hemostasis for peptic ulcer bleeding: a randomized controlled study (with video).

BACKGROUND AND AIMS: Peptic ulcer recurrent bleeding occurs in 20% to 30% of patients after standard endoscopic hemostasis, particularly within 4 days after the procedure. The application of additional tranexamic acid (TXA) to the ulcer may enhance hemostasis. This study investigated the effectiveness of TXA powder application on bleeding ulcers during endoscopic hemostasis. METHODS: This study enrolled patients who had peptic ulcer bleeding between March 2022 and February 2023. After undergoing standard endoscopic therapy, the patients were randomly assigned to either the TXA group or the standard group. In the TXA group, an additional 1.25 g of TXA powder was sprayed endoscopically on the ulcer. Both groups then received 3 days of high-dose (8 mg/h) continuous infusion proton pump inhibitor therapy. Second-look endoscopy was conducted on days 3 to 4. The primary end point of early treatment failure was defined as ulcer recurrent bleeding within 4 days or major stigmata of recent hemorrhage on the second-look endoscopy. RESULTS: Sixty patients (30 in each group) with peptic ulcer bleeding and balanced baseline characteristics were randomly assigned to a treatment group. The early treatment failure rate was lower in the TXA group (6.7%) than in the standard group (30%) (P = .042). The freedom from treatment failure periods for 4 and 28 days was significantly longer in the TXA group than in the standard group (P = .023). No adverse events from TXA were recorded. CONCLUSIONS: The precise delivery of topical TXA alongside standard endoscopic hemostasis reduced the early treatment failure rate in patients with bleeding peptic ulcers.

Diagnosis and treatment of primary seminoma of the prostate: A case report and review of literature.

BACKGROUND: Primary seminoma of the prostate (PSP) is a rare type of extragonadal germ cell tumour that is easily misdiagnosed, owing to the lack of specific clinical features. It is therefore necessary for clinicians to work toward improving the accuracy of PSP diagnosis. CASE SUMMARY: A 59-year-old male patient presenting with acute urinary retention was admitted to a local hospital. A misdiagnosis of benign prostatic hyperplasia led to an improper prostatectomy. Histopathology revealed PSP invading the bladder neck and bilateral seminal vesicles. Further radiotherapy treatment for the local lesion was performed, and the patient had a disease-free survival period of 96 mo. This case was analysed along with 13 other cases of PSP identified from the literature. Only four of the cases (28.6%) were initially confirmed by prostate biopsy. In these cases, imaging examinations showed an enlarged prostate (range 6-11 cm) involving the bladder neck (13/14). Of the 14 total cases, 11 (78.6%) presented typical pure seminoma cell features, staining strongly positive for placental alkaline phosphatase, CD117, and OCT4. The median age at diagnosis was 51 (range 27-59) years, and patients had a median progression-free survival time of 48 (range 6-156) mo after treatment by cisplatin-based chemotherapy combined with surgery or radiotherapy. The remaining three were cases of mixed embryonal tumours with focal seminoma, which had clinical features similar to those of pure PSP, in addition that they also had elevated serum alpha-fetoprotein, beta-human chorionic gonadotropin, and lactose dehydrogenase. CONCLUSION: PSP should be considered in patients younger than 60 years with an enlarged prostate invading the bladder neck. Further prostate biopsies may aid in proper PSP diagnosis. Cisplatin-based chemotherapy is still the main primary therapy for PSP.

Evolution of the Correa's cascade steps: A long-term endoscopic surveillance among non-ulcer dyspepsia and gastric ulcer after H. pylori eradication.

BACKGROUND: This study is aimed toward investigating the evolution of each Correa's step after Helicobacter pylori eradication in a long-term follow-up and exploring the factors correlated with a high-risk of gastric cancer. METHODS: A total of 1824 H. pylori-infected subjects were enrolled to receive screening endoscopy. Among them, 491 received surveillance endoscopy. The patients were divided into Correa's steps I to VI, from normal to gastric cancer. A group-based trajectory model was used to classify patients as persistent high-risk status or not. RESULTS: The prevalence rates of positive corpus-predominant gastritis index (CGI) were 20%-40% in all age groups and Correa's steps IV-V increased >35% after 50 years based on screening endoscopy. Successful eradication of H. pylori regressed CGI after the 1st year-and-thereafter (P < 0.05) and decreased Correa's step progression (Relative risk 0.66 [95% CI 0.49-0.89], P = 0.01); however, it did not regress OLGA and OLGIM. Not only in steps IV-V, but also in step III, the patients had a risk of developing gastric cancer (11.13-76.41 and 4.61 per 1000 person-years). Age (Hazard ratio 1.012 [1.003-1.020], P = 0.01), OLGA stages ≥ I (2.127 [1.558-2.903], P < 0.001), and OLGIM stages ≥ I (1.409 [1.119-1.774], P = 0.004) were correlated independently with a persistent high-risk status. CONCLUSION: The patients in Correa's steps III-V, but not I-II, were at risk of gastric cancer after H. pylori eradication. Age, OLGA stages ≥ I, and OLGIM stages ≥ I were independent factors correlated to a persistent high-risk of gastric cancer. The data may be useful when scheduling surveillance endoscopy for subjects in each Correa's step (NCT04527055).

Design and Implementation of Taizhou Integrated Prostate Screening.

A community-based prostate cancer screening program was conducted to assess the morbidity and associated factors for prostate cancer among the subpopulation of men aged ≥50 years in Taizhou, China. Taizhou Integrated Prostate Screening (TIPS) is a large, observational, population-based study of prostate cancer screening data based on serum prostate-specific antigen (PSA) concentrations. A pilot census of all male residents aged 50 years or older was conducted in Luqiao District, one of the field sites of the TIPS cohort in the city of Taizhou, Zhejiang. The interviewer-administered questionnaire evaluated demographic characteristics and environmental exposure factors. A total of 1,806 out of 3,516 participants completed the questionnaire. The overall prevalence of PSA ≥4 ng/mL was 11.5%, and included participants at low risk (9.2%), moderate risk (1.7%), and high risk (0.6%). Participants aged 60-69, 70-79, and ≥80 years had a 2.7-fold, 4.2-fold, and 6.5-fold higher risk of elevated PSA, respectively, in comparison with those aged 50 to 59 years (p < .001). Eighteen patients were diagnosed with prostate cancer, of whom 11 (61.1%) underwent radical surgery. This community-based PSA screening program indicated the results for early detection of prostate cancer among men aged ≥50 years. Early screening and appropriate clinical therapy for the management of prostate cancer are essential in this subpopulation.

A randomized controlled trial of a coping-focused family resilience intervention program for breast cancer patients: Study protocol.

Background: Breast cancer patients and their families are under various pressures in the process of disease diagnosis and treatment, which seriously threaten their physical and mental health. Findings from existing research suggest that good family resilience can help breast cancer families better adapt and cope with adversity and challenges. However, there are only a few intervention studies on family resilience and no intervention studies on resilience among the families of breast cancer patients. Therefore, this study aims to explore appropriate measures to improve the resilience level of breast cancer families and help them better cope with the disease. Objective: The purpose of this study protocol is to demonstrate a coping-focused family resilience intervention to increase the level of resilience in the families of breast cancer patients and help them better cope with adversity. Methods: The trial will recruit 80 breast cancer families and randomly assign them to experimental and control groups in a 1:1 ratio. The control group will receive routine care, and the intervention group will receive a 6-week one-on-one online family resilience intervention based on the control group. Two groups of subjects will be assessed at baseline and at 1 week, 1 month, and 3 months after the intervention. The primary outcome is family resilience, and the secondary outcomes are coping style, social support, family disease burden, and levels of anxiety and depression. Expected results: We hypothesized that after the intervention, the intervention group would have significantly higher levels of family resilience than the preintervention and control groups. In the intervention group, other aspects related to family resilience, such as family disease burden and anxiety and depression levels of patients and their families, were significantly alleviated, and disease coping and social support levels were improved accordingly. Discussion: If the program works, it can help breast cancer families identify family strengths and resources to proactively address challenges so that families can successfully navigate the crisis and patient and family recovery can be facilitated. It can also provide a practical path for clinical workers to help breast cancer families adjust rationally. Clinical Trial Registration: This study has been registered in the Chinese Clinical Trials Registry (Registration Number: http://www.chictr.org.cn/ChiCTR2100052108).

Clinical Benefit of Niraparib to TKI/mTORi-Resistance Metastatic ccRCC With BAP1-Frame Shift Mutation: Case Report and Literature Review.

Clear cell renal cell carcinoma (ccRCC) is the most common subtype of renal cancer. The top four mutant genes affecting the occurrence and progression of ccRCC are VHL, PBRM1, BAP1, and SETD2, respectively. Tyrosine kinase/mammalian target of rapamycin inhibitors (TKI/mTORis) with or without immunotherapy are the standard and effective therapy to metastatic ccRCC. Once TKI/mTORis fail to ccRCC, there is still a lack of other effective therapies. In this study, we reported a case in which a metastatic ccRCC patient (T2aN1M1) presented resistance after a 28-month treatment by sorafenib-axitinib-everolimus (TKI-TKI-mTORi). Subsequently, a frame shift pathogenic mutation, c.799_800del (p.Q267fs) in the exon10 of BAP1 in ccRCC, was revealed by targeted sequencing. Oral administration of nilapanib (PARP inhibitor) was further given, which may provide a new therapy for TKI/mTORi-resistance metastatic ccRCC. Fortunately, a partial response has been achieved and lasted for 5 months. Since the frequency of BAP1 mutations in ccRCC patients was approximately 10%-20%, as reported previously, we also tried to explore the potential mechanisms benefitting from the nilapanib. Moreover, the literature concerning BAP1 mutation and associated cancers including ccRCC is reviewed.

Age, male sex, smoking and metabolic syndrome as risk factors of advanced colorectal neoplasia for fecal immunochemical test negative patients.

BACKGROUND: Fecal immunochemical test (FIT) is worldwide strategy for colorectal cancer screening. The subjects with negative FIT still have the risk of an advanced colorectal neoplasia (AN), including adenoma with villous histology, high grade dysplasia or larger than 1 cm in size, or adenocarcinoma. The study determined the risk factors associated with AN in FIT-negative subjects. METHODS: The study included asymptomatic subjects who received health checkup colonoscopy and have provided FIT study within 6 months prior to colonoscopy. The risk factors to have AN in cases with negative FIT were analyzed. The numbers of colonoscopies needed to detect one AN were calculated for the subjects with different risk factors. RESULTS: There were 1411 cases, 85 with positive FIT and 1326 with negative FIT within 6 months before colonoscopy. In FIT positive and FIT negative cases, 45.9% and 34.6% were found to have colorectal adenoma, while 20.2% and 4.6% had AN, respectively. The univariate and multivariate logistic regression analyses showed that age more than 50 years old, male sex, smoking history and metabolic syndrome were the significant risk factors to have AN in the FIT negative cases. For cases with negative FIT to have these risk factors, the number of colonoscopies needed to detect one AN was 3.7, lower than 4.5 of the cases with positive FIT. CONCLUSION: For the cases with negative FIT, colonoscopy screening should be considered for those male patients over 50 years old, with a history of smoking and metabolic syndrome to detect AN.

Optimal Intervals of Ultrasonography Screening for Early Diagnosis of Hepatocellular Carcinoma in Taiwan.

Importance: There are different clinical practices regarding ultrasonography screening intervals for hepatocellular carcinoma (HCC) despite recommendations from international guidelines. Objective: To evaluate whether ultrasonography screening using intervals suggested by international guidelines is associated with cancer stage shifting, reductions in mortality, and improved quality of life (QoL) for patients with HCC. Design, Setting, and Participants: This nationwide comparative effectiveness research study estimated lifetime survival functions using interlinkages of 3 databases from Taiwan-the Taiwan National Health Insurance, Taiwan National Cancer Registry, and National Mortality Registry-combined with QoL measurements obtained from National Cheng Kung University Hospital. In total, 114 022 patients listed as having newly diagnosed HCC from 2002 through 2015 in the Taiwan National Cancer Registry were followed up until 2017. The QoL values of 1059 patients with HCC who visited National Cheng Kung University Hospital were prospectively measured with the European QoL-5 dimensions questionnaire from 2011 through 2019. Patients were categorized based on the time between their last ultrasonography screening and the index date (90 days prior to HCC diagnosis) as 1 of 5 subcohorts: 6 months (0-6 months), 12 months (7-12 months), 24 months (13-24 months), 36 months (25-36 months), and longer than 36 months (no screening in the previous 3 years). Data were analyzed from April 2020 to April 2021. Main Outcomes and Measures: Life expectancy, quality-adjusted life expectancy, and loss of life expectancy or loss of quality-adjusted life expectancy compared with age-, sex-, and calendar year-matched cohorts. Results: There were 59 194 patients with Barcelona Clinic Liver Cancer staging information, including 42 081 men (mean [SD] age, 62.2 [12.6] years) and 17 113 women (mean [SD] age, 69.0 [11.2] years). There was a consistent trend showing that the longer the interval between ultrasonography examinations, the higher the loss of life expectancy and loss of quality-adjusted life expectancy for both sexes. Loss of quality-adjusted life expectancy values for male subcohorts were 10.0 (95% CI, 9.1-10.9) quality-adjusted life-years (QALYs) for ultrasonography screening intervals of 6 months, 11.1 (95% CI, 10.4-11.8) QALYs for 12 months, 12.1 (95% CI, 11.5-12.7) QALYs for 24 months, 13.1 (95% CI, 12.6-13.6) QALYs for 36 months, and 14.6 (95% CI, 14.2-15.0) QALYs for longer than 36 months. Loss of quality-adjusted life expectancy values for female subcohorts were 9.0 (95% CI, 8.3-9.6) QALYs for 6 months, 9.7 (95% CI, 9.2-10.2) QALYs for 12 months, 10.3 (95% CI, 9.8-10.7) QALYs for 24 months, 10.7 (95% CI, 10.2-11.1) QALYs for 36 months, and 11.4 (95% CI, 11.0-11.8) QALYs for longer than 36 months. Patients with underlying hepatitis B virus infection or cirrhosis had the greatest improvement in life expectancy with shorter screening intervals. Conclusions and Relevance: Regular ultrasonography screening with intervals less than 6 to 12 months may be associated with early detection of HCC, save lives, and improve the quality of life for patients with HCC from a lifetime perspective.

The recurrent bleeding risk of a Forrest IIc lesion at the second-look endoscopy can be indicated by high Rockall scores ≥ 6.

BACKGROUND: The Forrest classification is widely applied to guide endoscopic hemostasis for peptic ulcer bleeding. Accordingly, practice guidelines suggest medical treatment only for ulcer with a Forrest IIc lesion because it has low rebleeding risk even without endoscopic therapy, ranging from 0 to 13%. However, the risk ranges widely and it is unclear who is at risk of rebleeding with such a lesion. This study assessed whether the Rockall score, which evaluates patients holistically, could indicate the risk of recurrent bleeding among patients with a Forrest IIc lesion at the second-look endoscopy. METHODS: Patients who had peptic ulcer bleeding with Ia-IIb lesions received endoscopic hemostasis at the primary endoscopy, and they were enrolled if their Ia-IIb lesions had been fading to IIc at the second-look endoscopy after 48- to 72-h intravenous proton pump inhibitor (PPI) infusion. Primary outcomes were rebleeding during the 4th-14th day and 4th-28th day after the first bleeding episode. RESULTS: The prospective cohort study enrolled 140 patients, who were divided into a Rockall scores ≥ 6 group or a Rockall scores < 6 group. The rebleeding rates in the Rockall scores ≥ 6 group and the Rockall scores < 6 group during the 4th-14th day and the 4th-28th day were 13/70 (18.6%) versus 2/70 (2.9%), p = 0.003 and 17/70 (24.3%) versus 3/70 (4.3%), p = 0.001, respectively, based on an intention-to-treat analysis and 5/62 (8.1%) versus 0/68 (0%), p = 0.023 and 6/59 (10.2%) versus 0/67 (0%), p = 0.009, respectively, based on a per-protocol analysis. The Kaplan-Meier curves showed that the Rockall scores ≥ 6 group had a significantly lower cumulative rebleeding-free proportion than the Rockall scores < 6 group (p = 0.01). CONCLUSIONS: Combined Rockall scores ≥ 6 on arrival with a Forrest IIc lesion at the second-look endoscopy can identify patients at risk of recurrent peptic ulcer bleeding following initial endoscopic and intravenous PPI treatment.

Lead Time Bias May Contribute to the Shorter Life Expectancy in Post-colonoscopy Colorectal Cancer.

BACKGROUND: The long-term outcomes of post-colonoscopy colorectal cancer have varied in previous studies. Our nationwide cohort analysis estimated expected years of life lost to adjust for lead time bias. AIM: We recalculated the long-term outcomes for post-colonoscopy and detected colorectal cancer. METHODS: Patients with colorectal cancer registered in the Taiwan Cancer Registry between 2002 and 2009 were enrolled. The detected group included 22,169 cases of colorectal cancer confirmed within 6 months after a colonoscopy. The post-colonoscopy group included 1653 cancer patients who received a colonoscopy 6-60 months before diagnosis. Patients were followed up until 2011. We simulated age-, sex-, and calendar year-matched referents from life tables in the Taiwan National Vital Statistics using a Monte Carlo method. The life expectancy and expected years of life lost of the cancer patients were obtained from extrapolation of the logit transformation of the survival ratio between the cancer cohorts and the referent groups. RESULTS: Post-colonoscopy colorectal cancer had shorter life expectancies than detected cancer (stages 2-4: 13.6 vs. 16.1 years; 8.7 vs. 12.6 years; 2.1 vs. 4.1 years, p < 0.001). The loss-of-life expectancy did not show this trend after adjusting for lead time bias. Post-colonoscopy colorectal cancer was found at an older age, more often proximal, and was associated with previous endoscopic polypectomy procedures (p < 0.001). CONCLUSIONS: Post-colonoscopy colorectal cancer leads to a shorter life expectancy, which appears partially explained by the presence of lead time bias. Quality assurance for colonoscopy and close surveillance for high risk groups would reduce post-colonoscopy colorectal cancer.

Gonorrhea and chlamydia prevalence in different anatomical sites among men who have sex with men: a cross-sectional study in Guangzhou, China.

BACKGROUND: A high rectal and oropharyngeal sexually transmitted infection (STI) burden has been reported among men who have sex with men (MSM) in many regions, but little data exists on rectal and oropharyngeal STIs among MSM in China. The purpose of this study was to determine the prevalence of gonorrhea and chlamydia at different anatomic sites among MSM in Guangzhou, China. METHODS: We recruited a cross-sectional sample of MSM in one Chinese city and collected detailed information about socio-demographic characteristics and sexual behaviors. Men had urine, rectal, and pharyngeal swab samples tested for gonorrhea and chlamydia using nucleic acid amplification tests (NAAT). Univariate and multivariate logistic regressions were used to evaluate factors associated with gonorrhea and chlamydia. Among men without any STI symptoms, we also examined the prevalence of gonorrhea and chlamydia by anatomical site. RESULTS: We enrolled 463 men between January 2015 and March 2017. A total of 58/463 (12.5%) of men had gonorrhea and 84/463 (18.1%) had chlamydia. MSM with gonorrhea were more likely to have been recruited from the STI clinic (OR 3.41, 95% CI 1.94-5.99), living with HIV (OR 2.41, 95% CI 1.18-4.92), diagnosed had STI co-infection (OR 2.55, 95% CI 1.39-4.69). MSM with chlamydia were more likely to be students (OR 1.8, 95% CI 0.99-3.39). Most gonorrhea (34/58, 59%) and chlamydia (64/84, 76%) infections were not associated with STI symptoms. CONCLUSION: Asymptomatic gonorrhea and chlamydia infection were common in this sample of Chinese MSM. Further research is necessary to determine optimal STI screening programs.

Male non-insulin users with type 2 diabetes mellitus are predisposed to gastric corpus-predominant inflammation after H. pylori infection.

BACKGROUND: Both H. pylori infection and diabetes increase the risk of gastric cancer. This study investigated whether patients with type 2 diabetes mellitus (T2DM) and H. pylori infection had more severe corpus gastric inflammation and higher prevalence of precancerous lesions than non-diabetic controls. METHODS: A total of 797 patients with type 2 diabetes mellitus were screened for H. pylori, of whom 264 had H. pylori infection. Of these patients, 129 received esophagogastroduodenoscopy to obtain topographic gastric specimens for gastric histology according to the modified Updated Sydney System, corpus-predominant gastritis index (CGI), Operative Link on Gastritis Assessment, and Operative Link on Gastric Intestinal Metaplasia Assessment. Non-diabetic dyspeptic patients who had H. pylori infection confirmed by esophagogastroduodenoscopy were enrolled as controls. RESULTS: The male as well as total T2DM patients had higher acute/chronic inflammatory and lymphoid follicle scores in the corpus than non-diabetic controls (p < 0.05). In contrast, the female T2DM patients had higher chronic inflammatory scores in the antrum than the controls (p < 0.05). In T2DM patients, the males had significantly higher rates of CGI than the females (p < 0.05). Multivariate logistic regression analysis showed that male patients (odds ratio: 2.28, 95% confidence interval: 1.11-4.69, p = 0.025) and non-insulin users (odds ratio: 0.33, 95% confidence interval: 0.15-0.74, p = 0.007) were independent factors for the presence of CGI in the H. pylori-infected patients with type 2 diabetes mellitus. CONCLUSIONS: Patients with type 2 diabetes mellitus and H. pylori infection had more severe corpus gastric inflammation than non-diabetic controls. Moreover, male gender and non-insulin users of T2DM patients were predisposed to have corpus-predominant gastritis after H. pylori infection.

Determination of artemisitene in rat plasma by ultra-performance liquid chromatography/tandem mass spectrometry and its application in pharmacokinetics.

RATIONALE: Artemisitene shows a wide variety of pharmacological activities, such as antioxidant protection in vitro and in vivo. It has been identified as a novel Nrf2 inducer. However, there is no report on an ultra-performance liquid chromatography/tandem mass spectrometry (UPLC/MS/MS) method to quantitate artemisitene in rat plasma and its application to a pharmacokinetic profile study. METHODS: An ACQUITY UPLC™ BEH Symmetry Shield RP18 column (1.7 µm, 2.1 mm × 100 mm) was used at a flow rate of 0.3 mL·min-1 . Mass detection was performed by electrospray ionization tandem mass spectrometry via multiple reaction monitoring (MRM) in positive mode. Plasma samples were pre-treated by a single-step extraction with 0.1% formic acid aqueous solutions-acetonitrile, and tolbutamide was used as internal standard. RESULTS: The calibration curve was from 0.98 to 1000 ng∙mL-1 (r2  = 0.995). The extraction recoveries were 61.5-79.4% and 81.7-94.6% for artemisitene and tolbutamide, respectively. The lower limit of quantification (LLOQ) was 0.98 ng∙mL-1 . The absolute bioavailability of artemisitene was 3.7% after intravenous and oral administration in rats. CONCLUSIONS: The UPLC/MS/MS assay was validated for linearity, accuracy, stability, extraction recovery, matrix effects, and intra-day and inter-day precision. The method, for the first time, achieved some pharmacokinetic parameters and was successfully applied to a pharmacokinetic study Copyright © 2017 John Wiley & Sons, Ltd.

Risk factors determining the need for second-look endoscopy for peptic ulcer bleeding after endoscopic hemostasis and proton pump inhibitor infusion.

BACKGROUND AND STUDY AIMS: The need for routine second-look endoscopy in cases of peptic ulcer bleeding remains uncertain. We investigated risk factors related to the need for second-look endoscopy after endoscopic hemostasis and proton pump inhibitor (PPI) infusion. PATIENTS AND METHODS: We prospectively enrolled 316 patients with peptic ulcer bleeding after endoscopic hemostasis. Second-look endoscopy was scheduled after 72-hour PPI infusion (Day-3 subgroup) or one day early (Day-2 subgroup). If early rebleeding developed within 3 days, emergent second-look endoscopy was conducted. Risk factors for early rebleeding (use of E2(nd) score to predict the need for early second-look endoscopy) and persistent major stigmata in the Day-3 subgroup (use of R2(nd) score to predict the need for routine second-look endoscopy) were analyzed using univariable and multivariable regression. RESULTS: Excluding 10 of 316 patients with early rebleeding, the rate of persistent major stigmata was lower in the Day-3 subgroup than in the Day-2 subgroup (4.8 % vs. 15.4 %, P  = 0.002). Endoscopic epinephrine-injection monotherapy and hypoalbuminemia < 3.0 g/dL were two independent risk factors for early rebleeding (P  ≤ 0.05). The Forrest Ia-Ib type and hypoalbuminemia < 3.5 g/dL were two independent risk factors for persistent major stigmata on the day-3 second-look endoscopy (P  < 0.05). The E2(nd) score was highly accurate for prediction of early rebleeding (AUROC 0.86; 95 % CI, 0.73~0.99), and the R2(nd) score could predict persistent major stigmata at second-look endoscopy (AUROC 0.84; 95 % CI, 0.69~0.99). CONCLUSIONS: For patients with peptic ulcer bleeding, E2(nd) and R2(nd) scores can indicate the need for early and routine second-look endoscopy, respectively (Trial registration identifier: NCT02197039).

Gastroesophageal Reflux Disease Diagnosis Using Hierarchical Heterogeneous Descriptor Fusion Support Vector Machine.

A new computer-aided diagnosis method is proposed to diagnose the gastroesophageal reflux disease (GERD) from endoscopic images of the esophageal-gastric junction. To avoid the interferences of different endoscope devices and automatic camera white balance adjustment, heterogeneous descriptors computed from heterogeneous color models are used to represent endoscopic images. Instead of concatenating these descriptors to a super vector, a hierarchical heterogeneous descriptor fusion support vector machine (HHDF-SVM) framework is proposed to simultaneously apply heterogeneous descriptors for GERD diagnosis and overcome the curse of dimensionality problem. During validation, heterogeneous descriptors are extracted from test endoscopic images at first. The classification result is obtained by using HHDF-SVM with heterogeneous descriptors. As shown in the experiments, our method can automatically diagnose GERD without any manual selection of region of interest and achieve better accuracy compared to states-of-the-art methods.

Helicobacter pylori test-and-treat program can be cost-effective to prevent gastric cancer in Taiwanese adults: referred to the nationwide reimbursement database.

BACKGROUND: Helicobacter pylori infection increases the risk of gastric cancer. The study aimed to compare cost-effectiveness ratios of H. pylori test-and-treat programs to prevent gastric cancer in Taiwan, referring to the nationwide reimbursement database and expected years of life lost. MATERIALS AND METHODS: During 1998-2009, there were 12,857 females and 24,945 males with gastric adenocarcinoma in Taiwan National Cancer Registry. They were followed up to 2010 and linked to the reimbursement database of National Health Insurance and the national mortality registry to determine lifetime health expenditures and expected years of life lost. Cost-effectiveness ratios of H. pylori test-and-treat programs for prevention of gastric adenocarcinoma were compared between screenings with (13) C-urea breath test and with anti-H. pylori IgG. RESULTS: The test-and-treat program with anti-H. pylori IgG to prevent gastric adenocarcinoma had lower incremental cost-effectiveness ratios than that with (13) C-urea breath test in both sexes (females: 244 vs 1071 US dollars/life-year; males: 312 vs 1431 US dollars/life-year). Cost saving would be achieved in an endemic area where H. pylori prevalence was >73.5%, or by selecting subpopulations with high absolute risk reduction rates of cancer after eradication. Moreover, expected years of life lost of gastric adenocarcinoma were higher and the incremental cost-effectiveness ratios of test-and-treat programs were more cost-effective in young adults (30-69 y/o) than in elders (≥70 y/o). CONCLUSIONS: The test-and-treat program with anti-H. pylori IgG shall be cost-effective to prevent gastric adenocarcinoma in a high endemic area, especially beginning at 30 years of age when H. pylori prevalence rates become stabilized.

Successful treatment of Kimura's disease with leflunomide and methylprednisolone: a case report.

Kimura's disease (KD) is an uncommon, chronic inflammatory disease characterized by tumor-like lesions in the soft tissue and lymph nodes and increased peripheral blood eosinophil counts and serum immunoglobulin E (IgE). Prednisone is widely used to treat the disease. Here, we reported a 59-year-old KD patient failed to response to prednisone. Leflunomide combined with methylprednisolone (Medrol) were carried out to treat KD and encouraging outcome was obtained during the medication and 1 year follow up period.

High risk for obesity in children with a subtype of developmental coordination disorder.

The purpose of this study was to compare the prevalence of overweight and obesity in typically developing (TD) children, children with developmental coordination disorder (DCD) and balance problems (DCD-BP), and children with DCD without balance problems (DCD-NBP). Two thousand and fifty-seven children (1095 boys, 962 girls) ages 9-12 years were recruited from 18 elementary schools in Taiwan. The Movement Assessment Battery for Children was used to assess motor coordination ability. International cut-off points for body mass index were used to classify participants into the following groups: normal-weight, overweight or obese. Compared with TD children, children in the DCD-BP group were more than twice as likely to be obese (OR=2.28; 95% CI=1.41-3.68). DCD-BP children were also more likely to be obese compared to DCD-NBP children (OR=1.79; 95% CI=1.02-3.16). Boys in the DCD-BP group were more likely to be obese when compared to DCD-BP girls (OR=3.12; 95% CI=1.28-7.57). Similarly, DCD-NBP boys were more likely to be obese when compared to DCD-NBP girls (OR=2.67; 95% CI=1.21-5.89). Children with both DCD and BP were significantly more likely to be obese when compared to TD and DCD-NBP children. From an intervention perspective, the inclusion of regular physical activity, including activities that encourage development of both balance and energy expenditure, may be required to prevent obesity in this population.

Breast cancer resistance protein-mediated efflux of luteolin glucuronides in HeLa cells overexpressing UDP-glucuronosyltransferase 1A9.

PURPOSE: UDP-glucuronosyltransferases (UGTs) are responsible for the formation of glucuronides of polyphenolic flavonoids. This study investigated the UGT1A9-mediated glucuronidation of luteolin and the kinetics of luteolin glucuronide efflux. METHOD: HeLa cells overexpressing UGT1A9 (HeLa-UGT1A9) were used to determine the kinetics of breast cancer resistance protein (BCRP)-mediated transport of luteolin glucuronides. Human UGT isoforms were used to determine glucuronidation rates. RESULTS: UGT1A9 was found to catalyze the production of four luteolin glucuronides, including three known monoglucuronides and a novel 3', 4'-diglucuronide. Ko143, a potent specific inhibitor of BCRP, significantly inhibited efflux of luteolin monoglucuronides from HeLa1A9 cells and increased their intracellular levels in a dose-dependent manner. The formation of luteolin diglucuronide was observed when intracellular concentration of total monoglucuronides went above 0.07 nM. CONCLUSIONS: Intracellular accumulation of diglucuronide was detected at high monoglucuronide concentrations (>0.07 nM). Diglucuronide production is speculated to be a compensatory pathway for luteolin disposition.
