Suitable Dose of Long-Term Tolvaptan to Reduce Heart Failure Rehospitalizations.

The short-term effectiveness of tolvaptan (TLV) for heart failure (HF) has been established, but the long-term effects are controversial. We investigated HF patients who could not discontinue both loop diuretics and TLV at discharge from AURORA (Acute Heart Failure Registry in Osaka Rosai Hospital). We compared the following factors at discharge between the RH group, consisting of patients with rehospitalizations due to worsening HF within 1 year after discharge (RH group), and non-RH group: age, gender, blood pressure, history of HF admission, electrocardiogram and echocardiographic parameters, atherosclerotic risk factors, laboratory data, and medications. Furthermore, we compared the effects of long-term low-dose TLV (≤ 7.5 mg/day) and high-dose TLV on HF rehospitalizations. The RH group consisted of 81 patients (58.7%). A multivariate analysis revealed that a history of HF admission and the TLV dose were independently and significantly associated with 1-year HF rehospitalizations. A receiver operating characteristic curve revealed that 7.5 mg of TLV was a suitable cutoff value for 1-year HF rehospitalizations. The Kaplan-Meier curves demonstrated that the HF rehospitalization free ratio was significantly higher in the low-dose TLV group (≤ 7.5 mg/day) than in high-dose TLV group over 1 year.In conclusion, the TLV dose, in addition to a history of HF admission, was associated with 1-year HF rehospitalizations in diuretic-dependent HF patients. In these patients, long-term low-dose TLV (≤ 7.5 mg/day) may be favorable for reducing HF rehospitalizations.

The effect of contact needle therapy on fatigue in patients with cancer in palliative care: A study protocol for a randomized controlled trial.

INTRODUCTION: Almost all patients with end-of-life cancer experience cancer-related fatigue; however, there are only a few known effective coping methods. OBJECTIVES: We will conduct a prospective, multi-center, single-blinded randomized controlled study to evaluate the efficacy of acupuncture for cancer-related fatigue in patients with end-of-life cancer. METHODS: We will enroll 120 patients with cancer hospitalized in a palliative care unit or receiving consultation from a palliative care team in four hospitals. We will add acupuncture treatment; specifically, contact needle therapy (CNT), consisting of an intervention per week period to the usual care. The primary outcome measure will be the Cancer Fatigue Scale (CFS) score while the secondary outcome measures will be the Numerical Rating Scale (NRS) score for fatigue, pain, and salivary amylase levels. CONCLUSION: We will evaluate the possibility of using acupuncture therapy, that is, CNT, in relieving fatigue sensation in patients with advanced cancer.

Efficacy of contact needle therapy for chemotherapy-induced peripheral neuropathy.

Cancer chemotherapy-induced peripheral neuropathy (CIPN) often results in discontinuation of treatment with potentially useful anticancer drugs and may deteriorate the patient's quality of life. This study investigated the effect of contact needle therapy (CNT) on CIPN caused by responsible chemotherapeutic agents as taxanes and oxaliplatin. Six patients with CIPN were treated with CNT. The severity of CIPN was evaluated using the Common Terminology Criteria for Adverse Events (CTCAE) version 4 and FACT/GOG-Ntx before and after CNT. After the treatment, all of the patients showed some improvement. Four patients showed apparent improvement in breakthrough pain. One of the cases had difficulty in walking because of CIPN in lower extremities, but after 2 times of CNT, he could walk without pain and could continue the chemotherapy. Although its putative mechanisms remain elusive, CNT has strong potential as an adjunctive therapy in CIPN. Well-designed clinical trials with adequate sample size and power are necessary to confirm the findings of this study.
