Efficacy and safety of a combination of emotional freedom technique with acupuncture versus acupuncture alone to treat psychiatric symptoms in Parkinson's disease: A protocol for a randomized, assessor-blind, parallel-group clinical trial.

BACKGROUND: Parkinson's disease (PD) is one of the most prevalent neurodegenerative diseases in world. As some psychiatric symptoms degrade the quality of life of patients with PD, a novel alternative non-pharmacological treatment is required. Acupuncture appears to be an effective and safe treatment for PD. The emotional freedom technique (EFT) is a type of psychological therapy that alleviates psychiatric symptoms by stimulating acupoints. In this study, we will compare the efficacy and safety of a combination of the EFT and acupuncture and acupuncture alone. METHODS: This study is a randomized, assessor-blind, parallel-group clinical trial. Eighty participants will be equally divided into experimental and control groups. Each participant will receive a total of 24 interventions over 12 weeks. The experimental group will receive EFT combined with acupuncture and the control group will receive acupuncture alone. The primary outcome is the change in the Beck Depression Inventory score from baseline to 12 weeks, and the secondary outcomes include change in the following variables: Beck Depression Inventory, Parkinson's disease sleep scale, State-Trait Anxiety Inventory, the Korean version of the Fatigue, Resistance, Ambulation, Illnesses, and Loss of weight questionnaire scale, and unified Parkinson's disease rating scale III and exercises. DISCUSSION: Acupuncture is a safe and effective treatment for motor and nonmotor symptoms in PD, and EFT appears to be safe and effective for a variety of psychiatric symptoms. In this study, we will investigate the potential of EFT combined with acupuncture to improve psychiatric symptoms in PD.

Bangpungtongsung-san for patients with major depressive disorder: study protocol for a randomized controlled phase II clinical trial.

BACKGROUND: Bangpungtongsung-san (BTS) is a representative herbal medicine that has been widely used for patients with obesity in east Asian countries. Various preclinical studies have demonstrated the anti-depressive effect of BTS granules in various animal models of depression. This phase II trial aimed to explore the efficacy and safety of BTS in human patients with depression. METHODS: A total of 126 patients diagnosed with major depressive disorder and who are not underweight (body mass index ≥ 18.5 kg/m2) will be enrolled in this study. Eligible participants will be randomly allocated into three groups: the high-dose BTS, low-dose BTS, and placebo groups in a 1:1:1 ratio. BTS or placebo granules will be orally administered twice a day for 8 weeks. The BTS and placebo granules will be made to have identical color, scent, and shape, and participants and investigators will be blinded to the allocation. The primary efficacy endpoint is the change from baseline of the 17-item Hamilton Depression Rating Scale total score at 8 weeks. The superiority of the high- and low-dose BTS granules to the placebo granules will be tested. DISCUSSION: The results of this clinical trial will provide evidence on the efficacy and safety of BTS for patients with major depressive disorder. This study will be conducted in accordance with ethical and regulatory guidelines, and the results will be submitted and published in international peer-reviewed journals.

Higher prevalence of metformin-induced vitamin B12 deficiency in sulfonylurea combination compared with insulin combination in patients with type 2 diabetes: a cross-sectional study.

Long-term and high-dose treatment with metformin is known to be associated with vitamin B12 deficiency in patients with type 2 diabetes. We investigated whether the prevalence of B12 deficiency was different in patients treated with different combination of hypoglycemic agents with metformin during the same time period. A total of 394 patients with type 2 diabetes treated with metformin and sulfonylurea (S+M group, n = 299) or metformin and insulin (I+M group, n = 95) were consecutively recruited. The vitamin B12 and folate levels were quantified using the chemiluminescent enzyme immunoassay. Vitamin B12 deficiency was defined as vitamin B12≤300 pg/mL without folate deficiency (folate>4 ng/mL). The mean age of and duration of diabetes in the subjects were 59.4±10.5 years and 12.2±6.7 years, respectively. The mean vitamin B12 level of the total population was 638.0±279.6 pg/mL. The mean serum B12 levels were significantly lower in the S+M group compared with the I+M group (600.0±266.5 vs. 757.7±287.6 pg/mL, P<0.001). The prevalence of vitamin B12 deficiency in the metformin-treated patients was significantly higher in the S+M group compared with the I+M group (17.4% vs. 4.2%, P = 0.001). After adjustment for various factors, such as age, sex, diabetic duration, duration or daily dose of metformin, diabetic complications, and presence of anemia, sulfonylurea use was a significant independent risk factor for B12 deficiency (OR = 4.74, 95% CI 1.41-15.99, P = 0.012). In conclusion, our study demonstrated that patients with type 2 diabetes who were treated with metformin combined with sulfonylurea require clinical attention for vitamin B12 deficiency and regular monitoring of their vitamin B12 levels.
