Filter by:With this pilot study, we are hoping to test the feasibility of a larger study in the future and to learn whether positive airway pressure therapy reduces the recurrence risk of atrial fibrillation after successful catheter ablation procedure among patients with atrial fibrillation and obstructive sleep apnea. The results from this study will help us refine the design for a future larger study, and will ultimately improve care of patients with obstructive sleep apnea and atrial fibrillation.
Atrial fibrillation (AF) is the most common arrhythmia in clinical practice with a prevalence reaching 5% in patients older than 65 years and an incidence that increases progressively with age.1 According to the most recent guidelines, class Ic anti-arrhythmic drugs are considered the first line treatment in patients without significant structural heart disease. Flecainide is effective in preventing AF recurrences in 31-61% of cases according to different studies.2-5 A recent study showed that the combination of Flecainide and Metoprolol improves effective rhythm control in patients with persistent symptomatic AF compared to Flecainide or Metoprolol alone.6 In contrast, the combination of Flecainide and Metoprolol conferred no significant benefit over Flecainide alone in patients with paroxysmal AF. This suggests different underlying mechanisms for paroxysmal and persistent AF. Pulmonary veins are likely the main focus triggering paroxysmal AF while in persistent AF the role of pulmonary veins is less important.
The purpose of this study is to determine the safety, tolerability, and immunogenicity in patients with pulmonary tuberculosis of an investigational DNA vaccine being developed for the prevention of relapse of tuberculosis.
Allogeneic stem cell transplantation (SCT) remains a powerful therapeutic modality for patients with acute myeloid leukemia (AML).The superior clinical outcomes of allogeneic human SCT versus chemotherapy alone as post-remission treatment could be related to the graft-versus-leukemia (GVL) effects of recovered donor T cells. Our previous study investigated both the association of MRD status with transplant outcomes in haplo-SCT and matched sibling donor transplantation(MSDT)， and also possible differences in the transplant outcomes of patients with positive pre-MRD (as determined by MFC) who underwent haplo-SCT versus MSDT. It provided new evidence that unmanipulated haplo-SCT is superior to matched sibling donor transplantation in eradicating pre-transplantation MRD, indicating that unmanipulated haploidentical allografts have stronger GVL effects.As to the AML patients in standard-risk, who have a positive MRD before MSDT, whether these patients should be given any relapse prevention is the question to be answered in this study. Interferon α-2b exerts a relatively strong immunomodulatory effect. It can kill AL cells by regulating T-cell and/or natural killer cell functions.Consequently, interferon α-2b may have potential value for high-risk AL patients after transplantation. The study hypothesis: Using interferon α-2b following hematopoietic stem cell transplantation in patients with standard-risk AML can further reduce relapse rate and improve leukemia-free survival.
For early stage of HCC, surgical resection or radiofrequency ablation (RFA) is the mainstay curative treatments. However, recurrence is still a major issue after the surgery or RFA. Only selected patients are eligible and tolerable to IFN-based treatment after surgical resection and the sustained virological response varied. Harvoni for genotype 1 HCV and sovaldi plus ribavirin for genotype 2 HCV can achieve high SVR and being recommended by AASLD and EASL. Mixed HCV genotype infection accounts for 10% of CHC patients in Taiwan. Sovaldi-based treatment plus ribavirin should be as effective as Sovaldi plus rivavirin in the treatment of genotype 2 HCV, as well as mixed genotype 1 and 2 HCV infection. As genotype 1 and 2 are the leading HCV genotypes in Taiwan, It can simplify the regimen of anti-HCV treatment in Taiwan by using Harvoni plus ribavirin, not only for genotype 1 and 2 HCV but also for mixed genotype 1 and 2 HCV infection. Although an unexpected high recurrence rate in HCC patients under DAA treatment was reported once. However, one recent study showed a low risk of HCC recurrence after DAA treatment. In this study, the investigators plan to enroll 130 HCV-HCC patients after confirming curative treatment for their HCC, either by surgery or RFA. For the cases fulfilling the inclusion/exclusion criteria, a 12 weeks Harvoni plus ribavirin treatment will be provided for all cases (single armed design). The primary objective of the study is annual recurrence-free survival after curative resection of HCV-HCC for up to 5 years. A hospital-based cohorts of HCV-related HCC undergoing surgical resection or RFA from Taipei Veterans General Hospital and Investigated Sites will be recruited as historical controls.
The primary hypothesis is that disease-free survival is improved in patients undergoing resection for tumor thought to be stage I-III primary non-small cell lung cancer in patients with combined general-epidural anesthesia & analgesia as compared to patients receiving general anesthesia and postoperative patient-controlled opioid analgesia. Patients having surgery for resection of potentially curable lung cancer will be randomized to combined general and epidural anesthesia or general anesthesia with opioid analgesia. The primary outcome will be disease-free survival.
Single arm, phase II exploratory trial to prospectively evaluate the impact of 68Ga-PSMA-PET/CT on the therapeutic management of patients with biological recurrent prostate cancer and negative, equivocal or oligometastatic disease after routine imaging diagnostic work-up.
Background: Urinary tract infections (UTIs), the most common infection in pregnancy,are associated with several maternal and fetal complications, including maternal septic shock, preterm labor, intrauterine growth restriction and intrauterine fetal death. Thus, the prevention of UTIs in pregnancy is a very important goal. Several studies have suggested that alterations in the vaginal flora were associated with recurrent UTIs, and probiotic administrations may have a role in preventing those infections. Nevertheless, this has never been tested in pregnant women.
There is substantial evidence linking inflammation to the initiation and perpetuation of AF. Although the precise mechanism by which inflammation contributes to the development of AF remains unclear, it has been proposed that inflammation may lead to "atrial myocarditis" with subsequent electrical and structural changes involving both atrial myocytes and extracellular matrix, leading finally to initiation and maintenance of AF. The high incidence of AF in post-operative cardiac surgeries, a state of intense inflammatory process, points out this association. Similarly, in non operative AF, inflammation appears to play a prominent role in both etiology and maintenance of AF. Indeed an increase of inflammatory markers to both paroxysmal and persistent AF was shown by numerous studies.
The combination of optimal cytoreductive operation (according to Desktop II criteria), HIPEC with Carboplatin 800 mg/m² KOF (Körperoberfläche) and following platinum-based systemic chemotherapy should be executed In patients with platinum-sensitive recurrence of ovarian carcinoma. Condition for HIPEC is attainment of optimal cytoreduction (R0) and experts judgement of a complication-free prolongation of narcosis after finishing the surgery. HIPEC will be administered additionally to standard therapy. If HIPEC was executed the number of systemic given platinum-based chemotherapy decreases for one cycle. This regime should be investigated in terms of safety of performance, quality of life for the patients and consequences for the following systemic chemotherapy.
