Living With Hiv

Persons living with HIV (PLWH) continuously experience symptom burdens. Their symptom prevalence and severity are also quite different. Mobile health (mHealth) applications (apps) offer exceptional opportunities for using personalized interventions when and where PLWH are needed. This study aimed to demonstrate the development process of the symptom management (SM) app and the structure and content of it. Our research team systematically searched for evidence-based resources and summarized up-to-date evidence for symptom management and health education. Our multidisciplinary research team that included physicians, nurses, software engineers, and nursing professors, evaluated the structure and content of the drafted app. Both quantitative data and qualitative results were collected at a group discussion meeting. Quantitative data were scores of sufficient evidence, situational suitability, practicability, cost-effectiveness, and understandability (ranged from one to four) for 119 items of the app contents, including the health tracking module, the self-assessment module, coping strategies for 18 symptoms (80 items), medication management, complementary therapy, diet management, exercise, relaxation techniques, and the obtaining support module. The SM app was comprised of eight modules and provided several personalized symptom management functions, including assessing symptoms and receiving different symptom management strategies, tracking health indicators, and communicating with medical staff. The SM app was a promising and flexible tool for HIV symptom management. It provided PLWH with personalized symptom management strategies and facilitated the case management for medical staff. Future studies are needed to further test the app’s usability among PLWH users and its effects on symptom management.

Abstract Background Gut-directed hypnosis (GDH) is a complimentary therapy for Inflammatory Bowel Disease (IBD), that can be learnt by patients to practice self-hypnosis. GDH in IBD has augmented remission and improved inflammation. GDH has a history of successful use for Irritable Bowel Syndrome (IBS). In IBD it may also improve IBS-like symptoms in remission and recovery from surgery. GDH is suitable for youth and adult IBD patients. In hypnosis, a relaxed state is inducted then suggestions to subconscious mind processes are made. In IBD, the mechanism of action of GDH is unknown but may influence the disease stress response. Aims Aims are the development of a GDH self-hypnosis protocol for IBD, with appropriate target symptoms. Patients first learn to practice with a clinician, then as complimentary psychotherapy for remission augmentation, IBS-like symptoms, and surgery recovery. Methods GDH is practiced first with a clinician, and then by patients as self-hypnosis (table 1). Patients receive psycho-education on GDH for IBD. Next, appropriate treatment goals are made, based on target symptoms. Relaxation techniques induce patient to a deeply relaxed state. Therapeutic suggestions specific to patient goals are given: verbal suggestions, visualizations, and post-hypnotic suggestions. Suggestions can focus on having a healthy digestive system, inflammation and symptoms reduction, and achievement and sustainment of remission. Patients emerge from hypnosis, are debriefed, and encouraged to practice ongoing self-hypnosis. Results In IBD, GDH self-hypnosis can be learnt from clinicians and practiced by patients as a complimentary therapy. Patients’ achievement and sustainment of remission, with clinical markers of inflammation can be monitored. Patients can monitor subjective improvement of IBS-like symptoms and post surgery, recovery progress can be monitored. Conclusions GDH has a history of use for IBS. In IBD, it has been shown to modulate remission, and may improve IBS-like symptoms, and in surgery recovery. The mechanism of action of GDH in IBD may influence the disease stress response. Clinicians trained in GDH are limited currently. Patients may learn GDH self- hypnosis to as a complimentary psychotherapy.

Negative Feelings

Stress belongs to the most frequent negative feelings people are confronted with in daily life. Strategies against acute stress include, e.g., relaxation techniques or medications, but it is also known that placebos can successfully reduce negative emotional stress. While it is widely held that placebos require deception to provoke a response, recent studies demonstrate intriguing evidence that placebos may work even without concealment (e.g., against anxiety or pain). Most of these studies are based on self-report questionnaires and do not include physiological measures. Here we report results of a study examining whether placebos without deception reduce acute stress. A total of 53 healthy individuals received either placebos without deception or no pills before participating in a laboratory stress test (Maastricht Acute Stress Test, MAST). We recorded self-report stress measures and cortisol responses before and after the MAST. Results showed no significant differences between the placebo and the control group, but when comparing participants with high relative to low beliefs in the power of placebos we found significant lower anxiety and cortisol responses for the placebo believers. These results show that non-deceptive placebos may successfully reduce acute anxiety and stress, but only in participants who had a strong belief in placebos. We discuss the results by suggesting that open-label placebos might be a possible treatment to reduce stress at least for some individuals.

Depression And Anxiety

Posttraumatic stress disorder (PTSD), an anxiety disorder with lifetime prevalence of 7.8%, is characterized by symptoms that develop following exposure to traumatic life events and that cause an immediate experience of intense fear, helplessness or horror. PTSD is marked by recurrent nightmares typified by the recall of intrusive experiences and by extended disturbance throughout sleep. Individuals with PTSD respond poorly to drug treatments for insomnia. The disadvantages of drug treatment for insomnia underline the importance of non-pharmacological alternatives. Thus, the present study had three aims: first, to compare the efficiency of two relaxation techniques (muscular relaxation and progressive music relaxation) in alleviating insomnia among individuals with PTSD using both objective and subjective measures of sleep quality; second, to examine whether these two techniques have different effects on psychological indicators of PTSD, such as depression and anxiety; and finally, to examine how initial PTSD symptom severity and baseline emotional measures are related to the efficiency of these two relaxation methods. Thirteen PTSD patients with no other major psychiatric or neurological disorders participated in the study. The study comprised one seven-day running-in, no-treatment period, followed by two seven-day experimental periods. The treatments constituted either music relaxation or muscle relaxation techniques at desired bedtime. These treatments were randomly assigned. During each of these three experimental periods, subjects' sleep was continuously monitored with a wrist actigraph (Ambulatory Monitoring, Inc.), and subjects were asked to fill out several questionnaires concerned with a wide spectrum of issues, such as sleep, depression, and anxiety. Analyses revealed a significant increase in objective and subjective sleep efficiency and a significant reduction in depression level following music relaxation. Moreover, following music relaxation, a highly significant negative correlation was found between improvement in objective sleep efficiency and reduction in depression scale. The study‘s findings provide evidence that music relaxation at bedtime can be used as treatment for insomnia among individuals with PTSD.
