Randomized Controlled Trial
Comparison of high flow nasal cannula with noninvasive ventilation in chronic obstructive pulmonary disease patients with hypercapnia in preventing postextubation respiratory failure: A pilot randomized controlled trial.
High flow nasal cannula (HFNC) has been shown to improve extubation outcomes in patients with hypoxemia, but the role of HFNC in weaning patients with chronic obstructive pulmonary disease (COPD) with hypercapnia from invasive ventilation is unclear. We compared the effects of HFNC to noninvasive ventilation (NIV) on postextubation vital signs and arterial blood gases (ABGs) among patients with COPD. Other outcomes included comfort scores, need for bronchoscopy, use of pulmonary medications, and chest physiotherapy. ⋯ No significant differences were found at 48 hr after extubation. In the HFNC group, comfort scores were better (3.55 ± 2.01 vs. 5.15 ± 2.28, p = 0.02) and fewer patients needed bronchoscopy for secretion management within 48 hr after extubation (2/22 vs. 9/20, p = 0.03). HFNC is a potential alternative to NIV to wean hypercapnic COPD patients with regard to vital signs and ABGs, HFNC improved patients' comfort and secretion clearance.

Randomized Controlled Trial
Promoting self-management of breast and nipple pain in breastfeeding women: Protocol of a pilot randomized controlled trial.
The majority of women experience pain during breastfeeding initiation with few strategies to manage breast and nipple pain. In fact, women cite breast and nipple pain as among the most common reasons for breastfeeding cessation. To address this important issue, we developed a breastfeeding self-management (BSM) intervention, based on the Individual and Family Self-Management Theory Framework. ⋯ Recruitment of 60 women intending to breastfeed occurred within 48 hr of delivery and women were randomized to either the intervention or usual care group. The BSM intervention group received BSM education modules that included information of how to manage breast and nipple pain and self-management support through biweekly texting from the study nurse, and were asked to complete a daily breastfeeding journal. Primary outcomes measured at baseline, 1, 2, and 6 weeks will be used to (a) evaluate feasibility, acceptability, and preliminary efficacy of the BSM intervention, and (b) assess the influence of protective and risk factors of breastfeeding pain (including individual genetic polymorphisms related to pain sensitivity) on process variables for self-management of breastfeeding and breastfeeding pain, and on proximal (breastfeeding pain severity and interference, breastfeeding frequency) and distal outcomes (breastfeeding exclusivity and duration and general well-being).

Randomized Controlled Trial
Pilot randomized controlled trial of auricular point acupressure for sleep disturbances in women with ovarian cancer.
Sleep disturbance is a significant problem affecting around 50% of cancer patients. Non-pharmacological interventions can be used to improve sleep quality in cancer patients, but little is known about the feasibility, acceptability, and effectiveness of auricular point acupressure (APA) to reduce sleep disturbance in women with ovarian cancer undergoing chemotherapy. A pilot randomized controlled trial was conducted at a publicly funded hospital in southern Taiwan. ⋯ APA treatment for women with ovarian cancer produced significantly improved sleep. Participants found the procedure easy to perform. Pilot findings support the feasibility of a longitudinal study with a larger, representative sample.

Randomized Controlled Trial
Decreased low back pain intensity and differential gene expression following Calmare®: results from a double-blinded randomized sham-controlled study.
In this double-blinded, randomized controlled trial we evaluated the effects of Calmare®, a non-invasive neurocutaneous electrical pain intervention, on lower back pain intensity as measured by the "worst" pain score and on pain interference using the Brief Pain Inventory-Short Form, on measures of pain sensitivity assessed by quantitative sensory testing, and on mRNA expression of pain sensitivity genes. Thirty participants were randomized to receive up to 10 sessions of Calmare® treatment (n = 15) or a sham treatment (n = 15) using the same device at a non-therapeutic threshold. ⋯ There were also significant differences in pain sensitivity and differential mRNA expression of 17 pain genes, suggesting that Calmare® can be effective in reducing pain intensity and interference in individuals with persistent low back pain by altering the mechanisms of enhanced pain sensitivity. Further study of long-term pain outcomes, particularly functional status, analgesic use and health care utilization, is warranted.

Randomized Controlled Trial
Biofeedback relaxation for pain associated with continuous passive motion in Taiwanese patients after total knee arthroplasty.
Effective pain management is crucial for patient recovery after total knee arthroplasty (TKA). Biofeedback therapy, which encourages relaxation and helps alleviate various conditions associated with stress, may help to decrease postoperative pain in patients undergoing TKA. A quasi- experimental design was used to investigate the efficacy of a biofeedback relaxation intervention in reducing pain associated with postoperative continuous passive motion (CPM) therapy. ⋯ The CPM-elicited pain score was calculated by subtracting the pre-CPM pain score from the post-CPM pain score. Results of repeated-measures analysis of variance showed intervention group reported significantly less pain caused by CPM than did the control group (f = 29.70, p < 0.001). The study results provide preliminary support for biofeedback relaxation, a non-invasive and non-pharmacological intervention, as a complementary treatment option for pain management in this population.
