A phase 1 study of biweekly nab-paclitaxel/oxaliplatin/S-1/LV for advanced upper gastrointestinal cancers: TCOG T1216 study.

BACKGROUND: Oxaliplatin- and fluoropyrimidine-based triplet regimens have demonstrated feasibility and efficacy in the treatment of upper gastrointestinal (UGI) cancers. Herein, we evaluate the feasibility and preliminary efficacy of biweekly nab-paclitaxel plus oxaliplatin and S-1/leucovorin (SOLAR) in chemonaïve UGI cancers. METHODS: A 3 + 3 phase 1 study was conducted to determine the maximal tolerated dose (MTD) of oxaliplatin in SOLAR (nab-paclitaxel [150 mg/m2 in D1], oxaliplatin [60, 75, or 85 mg/m2 in D1], and oral S-1/leucovorin [35 mg/m2 and 30 mg bid from D1 to D7]). The secondary endpoints were overall response rate (ORR), progression-free survival (PFS), overall survival (OS), and safety. RESULTS: Thirteen and 6 accruals were in the dose-escalation and MTD expansion cohorts, respectively. One of 6 patients at level III experienced dose-limiting toxicity (grade 3 diarrhea), which revealed that the MTD of oxaliplatin was 85 mg/m2. After a mean of 15.9 cycles of treatment, the most common treatment-related grade 3/4 toxicities were neutropenia (57.9%) and diarrhea (21.1%). The ORR was 63.2%. The median PFS and OS were 12.5 and 24.7 months, respectively. CONCLUSION: The current study revealed the MTD of oxaliplatin and demonstrated the preliminary efficacy of SOLAR in UGI cancers, which deserves further investigation.

Discovery of oral chemotherapeutic reversal agents for treating multidrug resistance cancer.

The major limitation of cancer treatment is multidrug resistance (MDR), which leads to the inactivation of chemotherapeutic drugs and greater than 90% mortality. To solve this ordeal, we applied ligand-based drug design and bioiosteric replacement strategy from an indazole to a pyrazole ring to discover compounds 27 and 43 with good potential for reversing drug resistance in combination with paclitaxel, and their reversal fold values were 53.2 and 51.0 at 5 µM, respectively, against an MDR cancer cell line (KBvin). Based on the PK profile results, we selected compound 43 with a longer half-life for mechanistic and animal experiments. Combination treatment with compound 43 and paclitaxel-induced apoptosis and enhanced subG1 by decreasing mitochondrial membrane potential in KBvin cells. In addition, 43 also inhibited P-gp function by interfering with ATPase activity. Meanwhile, cotreatment with compound 43 and paclitaxel significantly suppressed tumor growth (TGI = 55.5%) at a dose of 200 mg/kg (PO) in a xenograft model and showed no obvious liver or kidney toxicity by H&E staining. Overall, compound 43 may serve as a safe and effective oral resistance reversal chemotherapeutic agent.

Psychometric Properties and Measurement Invariance of the Awareness of Age-Related Change Short Form in Older Adult Samples from Taiwan and Germany.

BACKGROUND AND OBJECTIVES: This study examined the psychometric properties and measurement invariance of the 10-item Awareness of Age-Related Change Short Form (AARC-SF) questionnaire in a Chinese-speaking sample of older adults in Taiwan. RESEARCH DESIGN AND METHODS: Data from 292 participants (Mage = 77.64 years) in the Healthy Aging Longitudinal Study in Taiwan (HALST) cohort were used for Study 1, whereas data from young-old adult samples in Germany were used for Study 2. RESULTS: Study 1 showed that the AARC-SF had satisfactory reliability and validity for assessing adults' AARC in Taiwan. Analyses confirmed the two-factor structure of AARC-gains and AARC-losses. Study 2 demonstrated strong measurement invariance across men and women, whereas direct comparisons of the item scores between young-old adults and old-old adults need to be made with caution. Non-invariance of loadings indicated that certain items were more closely linked to AARC-gains and AARC-losses in Taiwan than in Germany. Non-invariance of intercepts suggested potential biases in comparing item scores between Taiwanese and German older adults. DISCUSSION AND IMPLICATIONS: The AARC-SF emerged as a reliable and valid instrument for capturing positive and negative subjective aging experiences among Taiwanese older adults. However, it is noteworthy that some items on the AARC-SF may solicit different responses from individuals of different ages and different countries of origin, requiring caution with age group and cross-cultural comparisons.

Systemic lupus erythematosus and autoimmune hepatitis overlap disease in a hospitalized systemic lupus erythematosus cohort.

Liver dysfunction in systemic lupus erythematosus (SLE) is caused by disease activity or secondary conditions like coexistent autoimmune liver diseases. In Taiwan, despite sporadically reported cases of SLE-autoimmune hepatitis (AIH) overlap disease, larger-scale monocentric investigations for such overlapping patients are not available. Retrospective analyses were performed in a hospitalized SLE cohort with 805 patients for identifying co-existent AIH from 2014 to 2023, focusing on distinct therapeutic modalities and differential diagnosis between SLE-AIH overlap and lupus hepatitis (LH). There were 5 cases (a 0.6% occurrence), all females aged 25-58 years (44 ± 13). Ages for the SLE diagnosis were 19-51 years (30 ± 13), while ages for the AIH diagnosis were 22-57 years (36 ± 14). Contradictory to interface hepatitis in SLE-AIH overlap, liver biopsy only demonstrated non-specific abnormalities in LH. Liver cirrhosis was identified in SLE-AIH overlap but not in LH. After corticosteroids/azathioprine therapy, there were normalized liver function in all LH. In 2 SLE-AIH overlap cases refractory to such therapy, one received B-cell depletion therapy (annual rituximab infusion, 375 mg/m2 weekly × 4) and another accepted living-donor liver transplantation from sibling due to advanced liver cirrhosis, leading to improved hepatic dysfunction in both.

DeepSP: Deep learning-based spatial properties to predict monoclonal antibody stability.

Therapeutic antibody development faces challenges due to high viscosities and aggregation tendencies. The spatial charge map (SCM) and spatial aggregation propensity (SAP) are computational techniques that aid in predicting viscosity and aggregation, respectively. These methods rely on structural data derived from molecular dynamics (MD) simulations, which are computationally demanding. DeepSCM, a deep learning surrogate model based on sequence information to predict SCM, was recently developed to screen high-concentration antibody viscosity. This study further utilized a dataset of 20,530 antibody sequences to train a convolutional neural network deep learning surrogate model called Deep Spatial Properties (DeepSP). DeepSP directly predicts SAP and SCM scores in different domains of antibody variable regions based solely on their sequences without performing MD simulations. The linear correlation coefficient between DeepSP scores and MD-derived scores for 30 properties achieved values between 0.76 and 0.96 with an average of 0.87. DeepSP descriptors were employed as features to build machine learning models to predict the aggregation rate of 21 antibodies, and the performance is similar to the results obtained from the previous study using MD simulations. This result demonstrates that the DeepSP approach significantly reduces the computational time required compared to MD simulations. The DeepSP model enables the rapid generation of 30 structural properties that can also be used as features in other research to train machine learning models for predicting various antibody stability using sequences only. DeepSP is freely available as an online tool via https://deepspwebapp.onrender.com and the codes and parameters are freely available at https://github.com/Lailabcode/DeepSP.

Risk factors of stent migration in esophageal cancer patients who underwent fully-covered self-expanding metal stents for malignant dysphagia or tracheoesophageal fistula.

BACKGROUND: More than 50% of esophageal cancer patients are diagnosed with advanced diseases and commonly experience dysphagia, some of whom even have tracheoesophageal fistula. Self-expandable metal stent (SEMS) is one of the recommended palliative methods, although complications such as chest pain and stent migration are not uncommon. The goal of this study was to examine the predictors of stent migration. METHODS: We conducted a retrospective cohort study to include patients with esophageal cancer and dysphagia/tracheoesophageal fistula. Clinicopathological information, stent characteristics and patient outcomes were collected for analysis, while side-effects of SEMS were recorded, potential predictors were examined, and patients' nutritional outcomes were compared in the migration and non-migration groups. RESULTS: A total of 54 patients with esophageal cancer who received fully covered SEMS between 2013 and 2022 were included. We found tumor across the esophagogastric junction (adjusted odds ratio (OR) = 32.64, P = 0.01) and the female sex (adjusted OR = 12.5, P = 0.02) were significant predictors for stent migration. There was a decreasing tendency in body mass index/body weight in migration and non-migration groups, but the former had a steeper downslope. CONCLUSION: Fully covered SEMS is a safe and effective strategy to palliate dysphagia or fistula. Tumor across esophagogastric junction and the female sex were higher risk predictors of stent migration. A careful patient selection would optimize the effects of SEMS placement, especially in those with short-expected lifespan.

Understanding and alleviating informal caregiver burden through the development and validation of a caregiver strain index-based model in Taiwan.

BACKGROUND: Quantifying the informal caregiver burden is important for understanding the risk factors associated with caregiver overload and for evaluating the effectiveness of services provided in Long-term Care (LTC). OBJECTIVE: This study aimed to develop and validate a Caregiver Strain Index (CSI)-based score for quantifying the informal caregiver burden, while the original dataset did not fully cover evaluation items commonly included in international assessments. Subsequently, we utilized the CSI-based score to pinpoint key caregiver burden risk factors, examine the initial timing of LTC services adoption, and assess the impact of LTC services on reducing caregiver burden. METHODS: The study analyzed over 28,000 LTC cases in Southern Taiwan from August 2019 to December 2022. Through multiple regression analysis, we identified significant risk factors associated with caregiver burden and examined changes in this burden after utilizing various services. Survival analysis was employed to explore the relationship between adopting the first LTC services and varying levels of caregiver burden. RESULTS: We identified 126 significant risk factors for caregiver burden. The most critical factors included caregiving for other disabled family members or children under the age of three (ß = 0.74, p < 0.001), the employment status of the caregiver (ß = 0.30-0.53, p < 0.001), the frailty of the care recipient (ß = 0.28-0.31, p < 0.001), and the behavioral symptoms of dementia in care recipients (ß = 0.28-2.60, p < 0.05). Generally, caregivers facing higher burdens sought LTC services earlier, and providing home care services alleviated the caregiver's burden. CONCLUSION: This comprehensive study suggests policy refinements to recognize high-risk caregivers better early and provide timely support to improve the overall well-being of both informal caregivers and care recipients.

A cyclic dipeptide for salinity stress alleviation and the trophic flexibility of endophyte provide insights into saltmarsh plant-microbe interactions.

In response to climate change, the nature of endophytes and their applications in sustainable agriculture have attracted the attention of academics and agro-industries. This work focused on the endophytic halophiles of the endangered Taiwanese salt marsh plant, Bolboschoenus planiculmis, and evaluated the functions of these isolates through in planta salinity stress alleviation assay using Arabidopsis. The endophytic strain Priestia megaterium BP01R2, which can promote plant growth and salinity tolerance, was further characterized through multi-omics approaches. The transcriptomics results suggested that BP01R2 could function by tuning hormone signal transduction, energy-producing metabolism, multiple stress responses, etc. In addition, the cyclodipeptide cyclo(L-Ala-Gly), which was identified by metabolomics analysis, was confirmed to contribute to the alleviation of salinity stress in stressed plants via exogenous supplementation. In this study, we used multi-omics approaches to investigate the genomics, metabolomics, and tropisms of endophytes, as well as the transcriptomics of plants in response to the endophyte. The results revealed the potential molecular mechanisms underlying the occurrence of biostimulant-based plant-endophyte symbioses with possible application in sustainable agriculture.

Efficacy of a sepsis clinical decision support system in identifying patients with sepsis in the emergency department.

BACKGROUND: Early prediction of sepsis onset is crucial for reducing mortality and the overall cost burden of sepsis treatment. Currently, few effective and accurate prediction tools are available for sepsis. Hence, in this study, we developed an effective sepsis clinical decision support system (S-CDSS) to assist emergency physicians to predict sepsis. METHODS: This study included patients who had visited the emergency department (ED) of Taipei Tzu Chi Hospital, Taiwan, between January 1, 2020, and June 31, 2022. The patients were divided into a derivation cohort (n = 70,758) and a validation cohort (n = 27,545). The derivation cohort was subjected to sixfold stratified cross-validation, reserving 20% of the data (n = 11,793) for model testing. The primary study outcome was a sepsis prediction (International Classification of Diseases, Tenth Revision, Clinical Modification) before discharge from the ED. The S-CDSS incorporated the LightGBM algorithm to ensure timely and accurate prediction of sepsis. The validation cohort was subjected to multivariate logistic regression to identify the associations of S-CDSS-based high- and medium-risk alerts with clinical outcomes in the overall patient cohort. For each clinical outcome in high- and medium-risk patients, we calculated the sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratios, and accuracy of S-CDSS-based predictions. RESULTS: The S-CDSS was integrated into our hospital information system. The system featured three risk warning labels (red, yellow, and white, indicating high, medium, and low risks, respectively) to alert emergency physicians. The sensitivity and specificity of the S-CDSS in the derivation cohort were 86.9% and 92.5%, respectively. In the validation cohort, high- and medium-risk alerts were significantly associated with all clinical outcomes, exhibiting high prediction specificity for intubation, general ward admission, intensive care unit admission, ED mortality, and in-hospital mortality (93.29%, 97.32%, 94.03%, 93.04%, and 93.97%, respectively). CONCLUSION: Our findings suggest that the S-CDSS can effectively identify patients with suspected sepsis in the ED. Furthermore, S-CDSS-based predictions appear to be strongly associated with clinical outcomes in patients with sepsis.

CLINICAL CHARACTERIZATION OF AQUEOUS AND VITREOUS RETINOL-BINDING PROTEIN 3 CONCENTRATIONS IN RELATION TO DIABETIC RETINOPATHY SEVERITY, RETINAL STRUCTURES, AND SYSTEMIC COMPLICATIONS.

PURPOSE: To evaluate Retinol-Binding Protein 3 (RBP3) from photoreceptors in aqueous and its association with vitreous concentrations, diabetic retinopathy (DR) severity, retinal layer thickness, and clinical characteristics in people with diabetes. METHODS: RBP3 concentration was measured by custom-developed enzyme-linked immunosorbent assay in aqueous and correlated with vitreous concentrations in patients from the 50-Year Medalist study and Beetham Eye Institute at Joslin Diabetes Center. RESULTS: Aqueous RBP3 concentration (N = 131) was elevated in eyes with no to mild DR (mean ± SD 0.7 nM ± 0.2) and decreased in eyes with moderate to severe DR (0.65 nM ± 0.3) and proliferative DR (0.5 nM ± 0.2, P < 0.001) compared to eyes without diabetes. Aqueous and vitreous RBP3 concentrations correlated with each other (r = 0.34, P = 0.001) and between fellow eyes (P < 0.0001). History of retinal surgery did not affect aqueous RBP3 concentrations, but cataract surgery affected both vitreous and aqueous levels. Elevated aqueous RBP3 concentration associated with increased thickness of the outer nuclear layer (P = 0.004) and correlated with hemoglobin A1c, whereas vitreous RBP3 concentrations correlated with diabetic systemic complications. CONCLUSION: These findings suggest that aqueous RBP3 concentration may be an important endogenous clinical retinal protective factor, a biomarker for DR severity, and a promising VEGF-independent clinical intervention target in DR.

Synthesis of selenophene-containing flavonols and 2-styrylchromones: Evaluation of their activities compared with selenophene-containing chalcones as potential anticancer agents.

Previously, we documented the synthesis and assessed the biological effects of chalcones containing selenium against HT-29 human colorectal adenocarcinoma cells, demonstrating their significant potential. As research on selenium-containing flavonoids remains limited, this article outlines our design and synthesis of three selenium-based flavonols and three 2-styrylchromones. We conducted evaluations of these compounds to determine their impact on human lung cancer cells (A549, H1975, CL1-0, and CL1-5) and their influence on normal lung fibroblast MRC5 cells. Additionally, we included selenium-based chalcones in our testing for comparative purposes. Our findings highlight that the simplest compound, designated as compound 1, exhibited the most promising performance among the tested molecules.

An integrative conceptual review of multiperspective frameworks in personality research and a roadmap for extended applications in organizational psychology.

Multiperspective frameworks, such as the social relations model, socioanalytic theory, the realistic accuracy model, the self-other knowledge asymmetry model, and the trait-reputation-identity model, have advanced understanding of personality over the last 40 years. Due to a resurgence of interest in multiperspective research on personality and other constructs in organizational psychology, we conducted an integrative conceptual review of these specific multirater frameworks and their application in work settings. Our review identifies similarities and differences in these frameworks and suggests that they collectively represent an invaluable resource for personality researchers and the broader field of organizational psychology. Through our review, we distinguish multiperspective frameworks from similar approaches (e.g., multirater designs), track the evolution of these frameworks, and leverage current applications of these frameworks to craft a future research agenda. Our review serves as a roadmap to help scholars apply multiperspective logic more thoroughly and systematically in personality research and beyond. We close with a discussion of practical implications. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Microbiome signatures associated with clinical stages of gastric Cancer: whole metagenome shotgun sequencing study.

BACKGROUND: Gastric cancer is one of the global health concerns. A series of studies on the stomach have confirmed the role of the microbiome in shaping gastrointestinal diseases. Delineation of microbiome signatures to distinguish chronic gastritis from gastric cancer will provide a non-invasive preventative and treatment strategy. In this study, we performed whole metagenome shotgun sequencing of fecal samples to enhance the detection of rare bacterial species and increase genome sequence coverage. Additionally, we employed multiple bioinformatics approaches to investigate the potential targets of the microbiome as an indicator of differentiating gastric cancer from chronic gastritis. RESULTS: A total of 65 patients were enrolled, comprising 33 individuals with chronic gastritis and 32 with gastric cancer. Within each group, the chronic gastritis group was sub-grouped into intestinal metaplasia (n = 15) and non-intestinal metaplasia (n = 18); the gastric cancer group, early stage (stages 1 and 2, n = 13) and late stage (stages 3 and 4, n = 19) cancer. No significant differences in alpha and beta diversities were detected among the patient groups. However, in a two-group univariate comparison, higher Fusobacteria abundance was identified in phylum; Fusobacteria presented higher abundance in gastric cancer (LDA scored 4.27, q = 0.041 in LEfSe). Age and sex-adjusted MaAsLin and Random Forest variable of importance (VIMP) analysis in species provided meaningful features; Bacteria_caccae was the most contributing species toward gastric cancer and late-stage cancer (beta:2.43, se:0.891, p:0.008, VIMP score:2.543). In contrast, Bifidobacterium_longum significantly contributed to chronic gastritis (beta:-1.8, se:0.699, p:0.009, VIMP score:1.988). Age, sex, and BMI-adjusted MasAsLin on metabolic pathway analysis showed that GLCMANNANAUT-PWY degradation was higher in gastric cancer and one of the contributing species was Fusobacterium_varium. CONCLUSION: Microbiomes belonging to the pathogenic phylum Fusobacteria and species Bacteroides_caccae and Streptococcus_anginosus can be significant targets for monitoring the progression of gastric cancer. Whereas Bifidobacterium_longum and Lachnospiraceae_bacterium_5_1_63FAA might be protection biomarkers against gastric cancer.

Pulse pressure is associated with decline in physical function in older adults.

OBJECTIVES: This study examined the associations between pulse pressure, hypertension, and the decline in physical function in a prospective framework. STUDY DESIGN: The Healthy Aging Longitudinal Study tracked a group of Taiwanese adults aged 55 or more over an average of 6.19 years to assess pulse pressure and decline in physical function, including in handgrip strength, gait speed, and 6-min walking distance, at baseline (2009-2013) and in the second phase of assessments (2013-2020). MAIN OUTCOME MEASURES: Pulse pressure was calculated as the difference between systolic and diastolic blood pressure values. Weakness, slowness, and low endurance were defined as decreases of ≥0.23 m/s (one standard deviation) in gait speed, ≥5.08 kg in handgrip strength, and ≥ 57.73 m in a 6-min walk, as determined from baseline to the second phase of assessment. Linear and logistic regressions were employed to evaluate the associations between pulse pressure, hypertension, and decline in physical function. RESULTS: Baseline pulse pressure was associated with future handgrip strength (beta = -0.017, p = 0.0362), gait speed (beta = -0.001, p < 0.0001), and 6-min walking distance (beta = -0.470, p < 0001). In multivariable models, only handgrip strength (beta = -0.016, p = 0.0135) and walking speed (beta = -0.001, p = 0.0042) remained significantly associated with future pulse pressure. Older adults with high systolic blood pressure (≥140 mmHg) and elevated pulse pressure (≥60 mmHg) exhibited a significantly increased risk of weakness (odds ratio: 1.30, 95 % confidence interval: 1.08-1.58), slowness (1.29, 1.04-1.59), and diminished endurance (1.25, 1.04-1.50) compared with the reference group, who exhibited systolic blood pressure of <140 mmHg and pulse pressure of <60 mmHg. CONCLUSIONS: Among older adults, pulse pressure is associated with a decline in physical function, especially in terms of strength and locomotion.

Risk stratification of best medical therapy for acute uncomplicated type B intramural hematoma.

OBJECTIVES: Best medical therapy (BMT) for acute uncomplicated type B intramural hematoma (TBIMH) is the current treatment guideline, but there is considerable controversy about subsequent clinical course and outcome, which may be associated with a significant failure rate. The purpose of this study was to identify potential risk factors for BMT failure and to develop a risk score to guide clinical decision making. METHODS: Patients with acute uncomplicated TBIMH between 2011 January and 2020 December were retrospectively studied. Logistic regression was applied to univariately assess potential risk predictors, and multivariable model results were then used to formulate a simplified predictive model for BMT failure. RESULTS: In a total of 61 patients, the overall rate of BMT failure was 57.4% (35/61), of which 48.6% (17/35) occurred within 28 days of onset. Logistic regression identified maximum descending aortic diameter (HR â€‹= â€‹1.99 CI â€‹= â€‹1.16-3.40, p â€‹= â€‹0.012), initial IMH thickness (HR â€‹= â€‹3.29, CI â€‹= â€‹1.28-8.46, p â€‹= â€‹0.013) and presence of focal contrast enhancement (HR â€‹= â€‹3.12, CI â€‹= â€‹1.49-6.54, p â€‹= â€‹0.003) as potential risk predictors of BMT failure. A risk score was calculated as follows: [Max DTA diameter (mm)∗0.6876 â€‹+ â€‹Max IMH thickness (mm)∗1.1918 â€‹+ â€‹PAU/ULP ∗1.1369]. Freedom from BMT failure at 1 year was 72% in patients with a risk score â€‹< â€‹4.12, compared with only 35.1% in those with a risk score â€‹â‰§ â€‹4.12. CONCLUSIONS: In a substantial proportion of patients with acute uncomplicated TBIMH, initial BMT failed. Based on the three initial computed tomographic imaging variables, this risk score could help stratify patients at high or low risk for BMT failure and provided additional information for early intervention.

Vascular Endothelial Growth Factor Inhibitors and the Risk of Aortic Aneurysm and Aortic Dissection.

Importance: Vascular endothelial growth factor pathway inhibitors (VPIs) pose a concern for aortic aneurysm (AA) and aortic dissection (AD), signaling potential vascular disease development. Objective: To investigate VPI-associated AA and AD. Design, Setting, and Participants: This case-control study with a nested design used full population data from a national claims database in Taiwan between 2011 and 2019. Eligible participants were aged 20 years or older with kidney, hepatic, gastrointestinal, or pancreatic cancer diagnosed between January 1, 2012, and December 31, 2019. The first cancer diagnosis date was defined as the cohort entry date. Cases were patients who received a diagnosis of AA or AD in hospitalizations or emergency visits between the cohort entry date and December 31, 2019. Controls were matched by ratio (up to 1:5) based on age, sex, cancer type, cohort entry date, and the index date (ie, the first AA or AD event date). Data analysis was performed between January 2022 and December 2023. Exposures: Use of the oral VPIs sorafenib, sunitinib, and pazopanib between cohort entry date and index date. Main Outcomes and Measures: In the primary analysis, AA and AD were evaluated compositely, while in the secondary analyses, they were evaluated separately. Adjusted odds ratios (aORs) were calculated using conditional logistic regression to assess the association with VPI use (sorafenib, sunitinib, and pazopanib) considering various VPI exposure windows and cumulative use. Results: A total of 1461 cases were included (mean [SD] age, 73.0 [12.3] years; 1118 male patients [76.5%]), matched to 7198 controls. AA or AD risk increased with a VPI exposure of 100 days or less before the index date (aOR, 2.10; 95% CI, 1.40-3.15), mainly from VPI-associated AD (aOR, 3.09; 95% CI, 1.77-5.39). Longer VPI duration (68 days or more: aOR, 2.64; 95% CI, 1.66-4.19) and higher cumulative dose (61 or more defined daily doses: aOR, 2.65; 95% CI, 1.66-4.23) increased the risk. Conclusions and Relevance: The use of the 3 study VPIs (sorafenib, sunitinib, and pazopanib) was associated with an increased risk of AA and AD in patients with cancer, essentially all of the risk from VPI-associated AD. Future studies are needed to determine the risk factors of VPI-associated AA and AD, as well as to establish a class effect.

The multicenter real-world report of the efficacies of 14-day esomeprazole-based and rabeprazole-based high-dose dual therapy in first-line Helicobacter pylori eradication in Taiwan.

BACKGROUND: High-dose dual therapy (HDDT) using proton-pump inhibitors (PPI) and amoxicillin attracted attention for its simplicity and lower adverse event profile. Besides, vonoprazan is not available worldwide. This real-world study aims to compare the efficacy of esomeprazole-based and rabeprazole-based HDDT regimens and to identify clinical factors influencing outcomes. METHODS: A retrospective study enrolled 346 Helicobacter pylori-infected naïve patients from January 2016 to August 2023. Patients were assigned to either a 14-day esomeprazole-based HDDT (EA-14; esomeprazole 40 mg t.i.d. and amoxicillin 750 mg q.i.d. for 14 days, n = 173) or a 14-day rabeprazole-based HDDT (RA-14; rabeprazole 20 mg and amoxicillin 750 mg q.i.d. for 14 days, n = 173). RESULTS: Five patients from the EA-14 group and 10 from the RA-14 group were lost to follow-up, resulting in 168 and 163 patients for the per-protocol (PP) analysis, respectively. Eradication rates for the EA-14 and RA-14 groups were 90.2% and 80.9% (P = 0.014) in intention-to-treat (ITT) analysis; and 92.9% and 85.9% (P = 0.039) in PP analysis. Adverse event rates were similar between the two groups (11.9% vs 11.7%, P = 0.944). In multiple logistic regression analysis, age≧60 was associated with eradication failure (P = 0.046) and a trend of significance for smoking (P = 0.060) in the EA-14 group but not in the RA-14 group. A trend of significance was also observed for eradication regimens (EA-14 vs RA-14) (P = 0.071). The antibiotic resistance rates were amoxicillin (2.3%), clarithromycin (14.7%), metronidazole (40.3%), and dual resistance to clarithromycin and metronidazole (7.0%). CONCLUSIONS: Esomeprazole-based HDDT achieved over 90% eradication rates but rabeprazole-based HDDT, which failed.

Computer-assisted image analysis of preexisting histological patterns of the cephalic vein to predict wrist arteriovenous fistula non-maturation.

BACKGROUND: We used computer-assisted image analysis to determine whether preexisting histological features of the cephalic vein influence the risk of non-maturation of wrist fistulas. METHODS: This study focused on patients aged 20-80 years who underwent their first wrist fistula creation. A total of 206 patients participated, and vein samples for Masson's trichrome staining were collected from 134 patients. From these, 94 patients provided a complete girth of the venous specimen for automatic image analysis. Maturation was assessed using ultrasound within 90 days after surgery. RESULTS: The collagen to muscle ratio in the target vein, measured by computer-assisted imaging, was a strong predictor of non-maturation in wrist fistulas. Receiver operating characteristic analysis revealed an area under the curve of 0.864 (95% confidence interval of 0.782-0.946, p < 0.001). The optimal cut-off value for the ratio was 1.138, as determined by the Youden index maximum method, with a sensitivity of 89.0% and specificity of 71.4%. For easy application, we used a cutoff value of 1.0; the non-maturation rates for patients with ratios >1 and ≤ 1 were 51.7% (15 out of 29 patients) and 9.2% (6 out of 65 patients), respectively. Chi-square testing revealed significantly different non-maturation rates between the two groups (X2 (1, N = 94) = 20.9, p < 0.01). CONCLUSION: Computer-assisted image interpretation can help to quantify the preexisting histological patterns of the cephalic vein, while the collagen-to-muscle ratio can predict non-maturation of wrist fistula development at an early stage.

10-Day versus 14-day bismuth quadruple therapy for first-line eradication of Helicobacter pylori infection: a randomised, open-label, non-inferiority trial.

Background: Bismuth quadruple therapy is currently consensus recommendation for first-line Helicobacter pylori (H. pylori) treatment; however, the optimal duration is unknown. We compared the efficacy of 10-day bismuth quadruple therapy with that of 14-day bismuth quadruple therapy for first-line eradication. Methods: For our multicentre, parallel randomised, open-label, and non-inferiority study, we recruited H. pylori treatment-naïve patients from one medical centre and one teaching hospital in Taiwan. Patients were randomly assigned (1:1) to receive 10-day (PBMT-10) or 14-day (PBMT-14) bismuth quadruple therapy. The primary outcome was the eradication rate as determined by intention-to-treat (ITT) and per-protocol (PP) analyses. The eradication rates between the two groups were compared using a one-sided α value of 0.025 and a non-inferiority margin of 7%. The secondary outcomes were the rate of adverse effects. The trial is registered with ClincialTrials.gov (NCT04527055). Findings: From August 3, 2020 to April 28, 2023, 313 H. pylori treatment-naïve patients (PBMT-10 = 157; PBMT-14 = 156) were enrolled. 35 patients were excluded from PP analyses. The eradication rates (95% CI) for PBMT-10 and PBMT-14 were respectively 92.4% (88.2%-96.5%) and 92.9% (88.9%-97.0%) by ITT analyses, and 97.9% (95.5%-100.0%) and 99.3% (97.8%-100.0%) by PP analyses. The eradication rates for PBMT-10 were non-inferior to those for PBMT-14 (absolute difference [lower boundary of the one-sided 97.5% CI] -0.6% [-6.7%], PNI = 0.020 in ITT analyses, -1.4% [-5.8%], PNI = 0.007 in PP analyses). The rates of overall adverse effects (54.1% versus 57.1%, P = 0.604) were similar between the two groups; nevertheless, the rates of dizziness (18.5% versus 34.0%, P = 0.003) and vomiting (4.5% versus 12.8%, P = 0.008) were lower in PBMT-10 than in PBMT-14. Interpretation: The 10-day bismuth quadruple therapy was non-inferior to the 14-day therapy as a first-line treatment for eradicating H. pylori infection and had no different rates of overall adverse effects, but less serious adverse events in terms of dizziness and vomiting.
