Functional constipation is a common clinical diagnosis that affects approximately 14% of the world’s population. Non-pharmacological therapies often represent the initial steps in management and may include lifestyle adjustments or changes such as physical activity and diet. Pharmacological options have been used when the non-pharmacological approach has been ineffective. Biofeedback therapy, surgery, sacral nerve stimulation, botulinum toxin injection, and vibrating capsules can be considered in scenarios where the laxatives are ineffective. Biofeedback therapy is highly effective and safe in treating dyssynergic defecation, which affects more than half of patients with chronic constipation. This paper overviews non-pharmacological therapies for functional constipation.

Background/Aims: Increasing resistance to clarithromycin (CAM) of Helicobacter pylori (H. pylori) is one of the main causes of recent decrease in eradication rate of standard triple therapy. The aim of this study was to evaluate the usefulness of 7-day tailored therapy based on the existence of CAM resistance. Methods: From January 2017 to May 2022, a total of 481 consecutive patients with H. pylori infection were recruited in Daegu Catholic University Medical Center. Treatment regimen was selected based on the result of CAM resistance test. Patients with CAM resistance (R group) were treated with bismuth-based quadruple therapy for 7 days. Patients without CAM resistance (S group) were treated with standard triple therapy for 7 days. Results: The overall H. pylori eradication rate was 89.4% (379 of 424) by per-protocol (PP) analysis. Patients with CAM resistance mutation included 166 patients (34.5%). The eradication rates of each group were 88.8% (135 of 152) and 89.7% (244 of 272) by PP analysis, for R and S group respectively. By intention-to-treat (ITT) analysis, the eradication rates were 81.3% (135 of 166) and 77.5% (244 of 315) for R and S group. CAM resistance was identified with a dual-priming oligonucleotide-based multiplex PCR. Conclusions: In spite of this high CAM resistance (34.5%), the eradication rate of 7-day tailored therapy based on the existence of CAM resistance was 89.4%. The 7-day tailored therapy based on CAM resistance could be an acceptable treatment selection strategy for H. pylori eradication.

Background/Aims: This study evaluated the incidence of venous thromboembolism (VTE) in patients with advanced pancreatic ductal adenocarcinoma (PDAC) at the authors’ institution and analyzed the risk factors associated with VTE and the overall survival (OS). Methods: One hundred and seventy patients with locally advanced or metastatic PDAC who received palliative chemotherapy at Daegu Catholic University Medical Center from January 2011 to December 2020 were included. Results: During a median follow-up period of 341 days, 24 patients (14.1%) developed VTE. Cumulative incidence values of VTE were 4.7% (95% confidence interval [CI], 2.39-9.22) at 90 days, 9.9% (95% CI, 6.14-15.59) at 180 days, and 16.9% (95% CI, 11.50-24.36) at 360 days. Multivariate analysis showed that a carbohydrate antigen 19-9 (CA 19-9) level over 1,000 U/mL (hazard ratio [HR], 2.666; 95% CI, 1.112-6.389; p=0.028) and a history of alcohol consumption (HR, 0.327; 95% CI, 0.109-0.981; p=0.046) were significant factors associated with VTE. Patients with VTE showed a shorter median survival (347 days vs. 556 days; p=0.041) than those without VTE. Multivariate analysis revealed VTE (HR, 1.850; 95% CI, 1.049-3.263; p=0.033) and CA 19-9 level over 1,000 U/mL (HR, 1.843; 95% CI, 1.113-3.052; p=0.017) to be significant risk factors associated with OS. Conclusions: The cumulative incidence of VTE in patients with advanced PDAC was 16.9% at 360 days. While a history of alcohol consumption was a protective factor, a high CA19-9 level was a risk factor for VTE. In addition, the occurrence of VTE was associated with poor prognosis.
