Pain in young children with burns : extent, course and influencing factors

Little evidence is available on the extent, course and influencing factors of pain in young children with burns. At present, reliable and valid measurement instruments to assess pain behavior in these children are available, implying that valuable insight into these questions can now be obtained. The aim of this study is to document the extent and course of pain behavior with the COMFORT-B, and to assess factors that may influence procedural pain. First, cutpoints for COMFORT-B scores were established by Rasch analysis to assess clinically relevant changes. Second, the extent of background and procedural pain behavior was assessed by descriptive statistics. Third, the course and factors that may influence procedural pain behavior were investigated by latent growth modeling. Trained nurses collected pain behavior data in 168 children (mean age 20 months, mean TBSA 6%, mean length of stay 10 days). Cutpoints of COMFORT-B scores were as follows: 6-13 (mild pain), 14-20 (moderate pain) and 21-30 (severe pain). This study suggests that background pain is more adequately treated than procedural pain. Factors that influenced baseline pain scores and/or the course over 8 days included TBSA, the number of surgical procedures, acetaminophen administration by the referring hospital, and the application of hydrofiber dressings. The implications of these findings are discussed

The implementation and evaluation of therapeutic touch in burn patients: An instructive experience of conducting a scientific study within a non-academic nursing setting

Objective: Evaluation of therapeutic touch (TT) in the nursing of burn patients; post hoc evaluation of the research process in a non-academic nursing setting. Methods: 38 burn patients received either TT or nursing presence. On admission, days 2, 5 and 10 of hospitalization, data were collected on anxiety for pain, salivary cortisol, and pain medication. Interviews with nurses were held concerning research in a non-academic setting. Results: Anxiety for pain was more reduced on day 10 in the TT-group. The TT-group was prescribed less morphine on day 1 and 2. On day 2 cortisol level before dressing changes was higher in the TT-group. The situational challenges of this study led to inconsistencies in data collection and a high patient attrition rate, weakening its statistical power. Conclusion: Conducting an effect study within daily nursing practice should not be done with a nursing staff inexperienced in research. Analysis of the remaining data justifies further research on TT for burn patients with pain, anxiety for pain, and cortisol levels as outcomes. Practice implications: Administering and evaluating TT during daily care requires nurses experienced both in TT and research, thus leading to less attrition and missing data, increasing the power of future studies.

Metabolic flexibility as an adaptation to energy resources and requirements in health and disease

The ability to efficiently adapt metabolism by substrate sensing, trafficking, storage, and utilization, dependent on availability and requirement, is known as metabolic flexibility. In this review, we discuss the breadth and depth of metabolic flexibility and its impact on health and disease. Metabolic flexibility is essential to maintain energy homeostasis in times of either caloric excess or caloric restriction, and in times of either low or high energy demand, such as during exercise. The liver, adipose tissue, and muscle govern systemic metabolic flexibility and manage nutrient sensing, uptake, transport, storage, and expenditure by communication via endocrine cues. At a molecular level, metabolic flexibility relies on the configuration of metabolic pathways, which are regulated by key metabolic enzymes and transcription factors, many of which interact closely with the mitochondria. Disrupted metabolic flexibility, or metabolic inflexibility, however, is associated with many pathological conditions including metabolic syndrome, type 2 diabetes mellitus, and cancer. Multiple factors such as dietary composition and feeding frequency, exercise training, and use of pharmacological compounds, influence metabolic flexibility and will be discussed here. Last, we outline important advances in metabolic flexibility research and discuss medical horizons and translational aspects
