Effect of melatonin on stress-induced hyperglycemia and insulin resistance in critically-ill patients: A randomized double-blind, placebo-controlled clinical trial.

BACKGROUND: Hyperglycemia is a common finding which is associated with increased mortality and morbidity among critically ill patients. There is currently no evidence that melatonin could improve stress induced hyperglycemia (SIH). In this study, we evaluated the effect of melatonin on blood sugar and insulin resistance (IR) in critically-ill patients. METHODS: 104 critically-ill patients with SIH divided into two groups, receiving melatonin (6 mg BD for 3 days) or placebo. Changes of blood sugar, IR indices including homeostasis model assessment for insulin resistance and homeostasis model assessment adiponectin (HOMA-AD) ratios, Glasgow coma scale (GCS) were evaluated on the 4th day of melatonin prescription. On the 7Th day of study, changes of ventilator dependency and delirium were considered. Mortality and intensive care unit (ICU) stay were also compared between groups. RESULTS: On day 4, patients in the melatonin group had significantly lower blood glucose and HMOA-IR level compared with the placebo group (P=0.04 and P=0.03, respectively) whereas HOMA-AD level did not differ significantly from placebo group (p>0.2). Also, we did not observe any significant difference in GCS level at this time between groups (p>0.2). On day 7, melatonin could not improve ventilator dependency and delirium significantly (p>0.2) and also could not reduce mortality and ICU stay in comparison with placebo (p>0.2, P=0.2, respectively). CONCLUSION: Melatonin supplementation showed positive effect on blood sugar and somehow insulin resistance whereas it could not improve ICU complications.

Improvement in use of best practice in the care of patients with oral mucositis in a comprehensive cancer center in Iran: a best practice implementation case study.

INTRODUCTION: Oral mucositis is a common debilitating complication of cancer treatments, particularly chemotherapy and radiation. OBJECTIVES: The purpose of this study was to improve oral mucositis prevention and control among cancer patients through the implementation of best practice guidelines in a tertiary referral center in Northern Iran. METHODS: A clinical audit design was utilized in this implementation project. A preimplementation audit was conducted against nine best practice criteria for the prevention and treatment of oral mucositis among new cases of cancer patients in November and December 2019. Fifty cancer patients and 20 nurses participated in this phase of the clinical audit. The next step included a facilitated multidisciplinary focus group identifying targeted strategies and implementing them, completed in late December 2019. A postimplementation audit was then conducted on another 50 cancer patients and the same 20 nurses in January and early February 2020. The project utilized the Joanna Briggs Institute Practical Application of Clinical Evidence System and Getting Research into Practice software. RESULTS: The preimplementation audit revealed gaps between the current practice and best practice across eight of the nine criteria. After implementing the targeted strategies, the outcomes improved across most of the criteria in the follow-up audit: 80% increase was observed in compliance of staff education, 100% increase in providing standard oral hygiene protocol in place, 64% increase in carrying out a dental examination and conducting initial oral cavity examination, and also 34% increase in conducting of ongoing oral cavity examination by a dentist, and finally 100% increase in providing preventive and therapeutic oral care regimens in place and oral pain assessment using a validated tool. CONCLUSION: The results of this project indicate that clinical auditing is an effective approach to the assessment of evidence-based care practices for oral mucositis among new cancer patients. Evidence-based oral mucositis management among cancer patients can be achieved by educating the patients and nursing staff using the newest guidelines and dentists' comprehensive dental and oral hygiene examinations.

Comparison of the effects of the Feldenkrais method versus core stability exercise in the management of chronic low back pain: a randomised control trial.

OBJECTIVE: To investigate the effect of the Feldenkrais method versus core stability exercises on pain, disability, quality of life and interoceptive awareness in patients with chronic non-specific low back pain. DESIGN: A single-blinded, randomised, controlled trial. SETTING: Outpatient, sports medicine clinic of Mazandaran medical university. PARTICIPANTS: Sixty patients with chronic non-specific low back pain randomised equally into the Feldenkrais method versus core stability exercises groups. INTERVENTION: Intervention group received Feldenkrais method consisting of training theoretical content and supervised exercise therapy two sessions per week for five weeks. Control group received educational programme and home-based core stability exercises for five weeks. OUTCOME MEASURES: All patients were examined by World Health Organization's Quality of life Questionnaire, McGill Pain Questionnaire, Oswestry Disability Questionnaire and Multidimensional Assessment of Interoceptive Awareness Questionnaire. All outcomes were measured at baseline and the end of the intervention. RESULTS: There were statistically significant differences between groups for quality of life (P = 0.006, from 45.51 to 60.49), interoceptive awareness (P > 0.001, from 2.74 to 4.06) and disability (P = 0.021, from 27.17 to 14.5) in favour of the Feldenkrais method. McGill pain score significantly decreased in both the Feldenkrais (from 15.33 to 3.63) and control groups (from 13.17 to 4.17), but there were no between-groups differences (P = 0.16). CONCLUSION: Feldenkrais method intervention gave increased benefits in improving quality of life, improving interoceptive awareness and reducing disability index.
