Full title: Orange Interventions for Symptoms Associated With Dimethyl Sulfoxide During Stem Cell Reinfusions: A Feasibility Study.
BACKGROUND:: For over 2 decades, oncology nurses at a regional comprehensive cancer center offered sliced oranges to patients during the reinfusion of autologous hematopoietic progenitor cells (HPCs) to relieve symptoms associated with the preservative dimethyl sulfoxide (DMSO). OBJECTIVES:: This randomized pilot study examined feasibility and efficacy of sliced orange intervention (OI), orange aromatherapy intervention (OAI), or deep breathing (control) to address unpleasant adverse effects during HPC infusion. METHODS:: Orange intervention sniffed or tasted a quartered orange, OAI sniffed orange aromatherapy, and control took deep breaths. Perceived "symptom intensity" for tickle/cough urge, nausea, retching, and perceived "relief" were measured on 0- to 10-point numerical scales. RESULTS:: Sixty of 72 eligible patients consented to participate and were randomized to OI (n = 19), OAI (n = 23), or control (n =18). Study personnel successfully administered study procedures. Over the course of 2 bags of cells infused, the OI group reported significantly greater relief with the intervention (P = .032). Among participants less than 90 kg, OI group reported significantly lower symptom intensity (P = .012). CONCLUSIONS:: Results suggest a feasible protocol and potential efficacy of sliced oranges for treating symptoms associated with DMSO-preserved stem cells. Study procedures provide a tested protocol for future studies. Follow-up study is warranted to confirm these findings and evaluate other treatment options. IMPLICATIONS FOR PRACTICE:: Oranges offer a simple, noninvasive intervention for relieving symptoms associated with DMSO preservative during autologous HPC infusion.

In general, there are three types of mental health disorders with which I am concerned. The first category, and probably most common, involves disorders related to fears, anxieties, trauma, and phobias. These almost always related to learned patterns. Something happened in their mind and body fell to adapt appropriately. The second category is personality disorders. Again, this involves a person's ability to adapt and adjust to the unknown. A personality is normally considered one's beliefs, values, and behaviors. Together these are reflected as patterns. Once something happens that is...
Much has been said about the desire to change. Indeed, this is the topic of many self-help experts, personal coaches, and even professional counselors, psychologists, and other psychotherapists. However, little is ever said about why a person would want to transform.
The first thing that I notice is that there is a universal desire for happiness. While many people will never be content – even if their situation is the envy of many others – generally when a person has something that is causing a high level of dissatisfaction in their life, then they develop an urge to become...
When you feel that there is absolutely no way that you can cope with or resolve with stressful situation, it is quite easy to go into a panic mode. When feelings of panic are later triggered easily and frequently, you have established a learning in your mind and body. This learned behavior is normally referred to as a panic attach. Even though triggering event may seem illogical, you have trained yourself to react this way. The goal now is to reverse this habitual behavior.
The mature human brain is quite capable of appropriately processing threats. When a potential threat...
