Randomized Controlled Trial
Efficacy of ultra-micronized palmitoylethanolamide (um-PEA) in geriatric patients with chronic pain: study protocol for a series of N-of-1 randomized trials.
Chronic pain in older people is highly prevalent, often underestimated, and associated with adverse outcomes. Most available analgesic drugs are often either ineffective or not tolerated, with many side effects. Palmitoylethanolamide (PEA) is an endogenous widely distributed N-acylethanolamina involved in neuroinflammation and pain-generating processes. Formulations containing ultra-micronized palmitoylethanolamide (um-PEA) are available but their effectiveness on chronic pain in highly heterogeneous geriatric patients is not clear and probably not generalizable. We planned to adopt the N-of-1 trial approach to test the effectiveness of um-PEA objectively at the individual level in our older outpatients. ⋯ While pursuing an ultimate clinical objective, i.e. to empirically and objectively decide the best treatment choice for an individual older patient with chronic pain, these series of geriatric N-of-1 trials on PEA will bring the principles of evidence-based medicine into the care of patients not usually represented in conventional randomized controlled trials, and realize a patient-centered outcome approach necessary to improve appropriate prescribing in elderly patients with multimorbidity and polypharmacy.

Randomized Controlled Trial
Promoting weight loss through diet and exercise in overweight or obese breast cancer survivors (InForma): study protocol for a randomized controlled trial.
Most women with breast cancer experience a progressive weight gain during and after treatment. Obesity is associated with an increased risk of recurrence, contralateral breast cancer, and death. Physical activity after cancer diagnosis has been reported to have positive effects on body composition and quality of life. We present the protocol of the InForma study, a trial testing the efficacy of an intervention on weight loss (≥5 % of the baseline body weight) in a group of overweight or obese breast cancer survivors. ⋯ While there is a rising concern about the role of obesity in cancer recurrence and survival, this trial with its multi-arm design, motivational approach and use of a pedometer device will provide important insights regarding the most effective approach in promoting weight control in breast cancer survivors.

Randomized Controlled Trial Multicenter Study Comparative Study
Standardised Chinese herbal treatment delivered by GPs compared with individualised treatment administered by practitioners of Chinese herbal medicine for women with recurrent urinary tract infections (RUTI): study protocol for a randomised controlled trial.
In the UK, urinary tract infections (UTIs) are the most common bacterial infection presented by women in primary care. Recurrent urinary tract infections (RUTIs) are defined as three episodes of UTI in the last 12 months, or two episodes in the last 6 months. Between 20 and 30 % of women who have had one episode of UTI will have an RUTI, and approximately 25 % of these will develop subsequent recurrent episodes. RUTIs can have a significant negative effect on the quality of life, and have a high impact on health care costs as a result of outpatient visits, diagnostic tests and prescriptions. Chinese herbal medicine (CHM) has a recorded history of treatments for the symptoms of UTIs for more than 2000 years. More recent clinical research in China has provided some preliminary evidence that CHM can alleviate the symptoms of UTIs and reduce the rate of recurrence, but more rigorous investigation is required. ⋯ The RUTI trial is the first instance of CHM delivered as a clinical trial of an investigatory medicinal product in the UK. This study provides important information regarding the feasibility and acceptability of researching and using CHM in Primary care. Once completed, it will provide provisional estimates of the variance of change in continuous outcomes to inform a power calculation for a larger, more definitive trial.

Randomized Controlled Trial
Mass mosquito trapping for malaria control in western Kenya: study protocol for a stepped wedge cluster-randomised trial.
Increasing levels of insecticide resistance as well as outdoor, residual transmission of malaria threaten the efficacy of existing vector control tools used against malaria mosquitoes. The development of odour-baited mosquito traps has led to the possibility of controlling malaria through mass trapping of malaria vectors. Through daily removal trapping against a background of continued bed net use it is anticipated that vector populations could be suppressed to a level where continued transmission of malaria will no longer be possible. ⋯ This study will be the first to evaluate whether the principle of solar-powered mass mosquito trapping could be an effective tool for elimination of malaria. If proven to be effective, this novel approach to malaria control would be a valuable addition to the existing strategies of long-lasting insecticide-treated nets and case management. Sociological studies provide a knowledge base for understanding the usage of this novel tool.

Randomized Controlled Trial
Varied flushing frequency and volume to prevent peripheral intravenous catheter failure: a pilot, factorial randomised controlled trial in adult medical-surgical hospital patients.
Research has identified high failure rates of peripheral intravenous catheter (PIVC) and varied flushing practices. ⋯ Neither increased flushing volume nor frequency significantly altered the risk of PIVC failure. Female gender, hand/posterior wrist placement and episodes of access (flushes and medication) may be more important. Larger, definitive trials are feasible and required.
