Complementary medicine in chronic cancer care

Daniel A. Monti — Fri, 16 Feb 2007 13:58:39 PST

Although advancements in cancer care have led to increased cure rates and survival times, those coping with the long-term sequelae of a cancer diagnosis often report high levels of distress, poor health-related quality of life, and unmet psychosocial needs. The shortcomings of the conventional biomedical system at sufficiently addressing these chronic illness issues are a primary reason that many patients turn to complementary and alternative medicine (CAM). Although patients usually use such treatments in addition to conventional care, they often do not discuss doing so with their conventional physicians, who are perceived as being unreceptive to the topic. Physicians may feel uninformed about CAM treatments, especially given the relatively small amount of data on the topic available in the medical literature. This article reviews a few CAM modalities commonly used by cancer survivors and those with chronic cancer illness, with a particular focus on familiarizing physicians with treatments that may potentially complement regular oncologic care by decreasing stress and enhancing health-related quality of life.

Light therapy for seasonal affective disorder with blue narrow-band light-emitting diodes (LEDs)

Gena Glickman — Fri, 19 Jan 2007 14:07:13 PST

Background: While light has proven an effective treatment for Seasonal Affective Disorder (SAD), an optimal wavelength combination has not been determined. Short wavelength light (blue) has demonstrated potency as a stimulus for acute melatonin suppression and circadian phase shifting. Methods: This study tested the efficacy of short wavelength light therapy for SAD. Blue light emitting diode (LED) units produced 468 nm light at 607 �W/cm2 (27 nm half-peak bandwidth); dim red LED units provided 654 nm at 34 �W/cm2 (21 nm half-peak bandwidth). Patients with major depression with a seasonal pattern, a score of ≥20 on the Structured Interview Guide for the Hamilton Depression Rating Scale-SAD version (SIGH-SAD) and normal sleeping patterns (routine bedtimes between 10:00 pm and midnight) received 45 minutes of morning light treatment daily for 3 weeks. Twenty-four patients completed treatment following random assignment of condition (blue vs. red light). The SIGH-SAD was administered weekly. Results: Mixed-effects analyses of covariance determined that the short wavelength light treatment decreased SIGH-SAD scores significantly more than the dimmer red light condition (F = 6.45, p = .019 for average over the post-treatment times). Conclusions: Narrow bandwidth blue light at 607 �W/cm2 outperforms dimmer red light in reversing symptoms of major depression with a seasonal pattern.

Mindfulness-based stress reduction and health-related quality of life in a heterogeneous patient population

Diane K. Reibel — Fri, 19 Jan 2007 14:07:11 PST

This study examined the effects of mindfulness-based stress reduction (MBSR) on health-related quality of life and physical and psychological symptomatology in a heterogeneous patient population. Patients (n=136) participated in an 8-week MBSR program and were required to practice 20 min of meditation daily. Pre- and post-intervention data were collected by using the Short-Form Health Survey (SF-36), Medical Symptom Checklist (MSCL) and Symptom Checklist-90 Revised (SCL-90-R). Health-related quality of life was enhanced as demonstrated by improvement on all indices of the SF-36, including vitality, bodily pain, role limitations caused by physical health, and social functioning (all P<.01). Alleviation of physical symptoms was revealed by a 28% reduction on the MSCL (P<.0001). Decreased psychological distress was indicated on the SCL-90-R by a 38% reduction on the Global Severity Index, a 44% reduction on the anxiety subscale, and a 34% reduction on the depression subscale (all P<.0001). One-year follow-up revealed maintenance of initial improvements on several outcome parameters. We conclude that a group mindfulness meditation training program can enhance functional status and well-being and reduce physical symptoms and psychological distress in a heterogeneous patient population and that the intervention may have long-term beneficial effects.

Mindfulness-based stress reduction lowers psychological distress in medical students

Steven Rosenzweig MD — Fri, 19 Jan 2007 08:59:45 PST

Background: Medical students confront significant academic, psychosocial, and existential stressors throughout their training. Mindfulness-based stress reduction (MBSR) is an educational intervention designed to improve coping skills and reduce emotional distress. Purpose: The purpose of this study was to examine the effectiveness of the MBSR intervention in a prospective, nonrandomized, cohort-controlled study. Methods: Second-year students (n = 140) elected to participate in a 10-week MBSR seminar. Controls (n = 162) participated in a didactic seminar on complementary medicine. Profile of Mood States (POMS) was administered preintervention and postintervention. Results: Baseline total mood disturbance (TMD) was greater in the MBSR group compared with controls (38.7 � 33.3 vs. 28.0 � 31.2; p < .01). Despite this initial difference, the MBSR group scored significantly lower in TMD at the completion of the intervention period (31.8 � 33.8 vs. 38.6 � 32.8; p < .05). Significant effects were also observed on Tension-Anxiety, Confusion-Bewilderment, Fatigue-Inertia, and Vigor-Activity subscales. Conclusion: MBSR may be an effective stress management intervention for medical students.
