Effects of an integrated yoga program in modulating perceived stress levels, anxiety, as well as depression levels and radiation-induced DNA damage were studied in 68 breast cancer patients undergoing radiotherapy. Two psychological questionnaires-Hospital Anxiety and Depression Scale (HADS) and Perceived Stress Scale (PSS)-and DNA damage assay were used in the study. There was a significant decrease in the HADS scores in the yoga intervention group, whereas the control group displayed an increase in these scores. Mean PSS was decreased in the yoga group, whereas the control group did not show any change pre-and postradiotherapy. Radiation-induced DNA damage was significantly elevated in both the yoga and control groups after radiotherapy, but the postradiotherapy DNA damage in the yoga group was slightly less when compared to the control group. An integrated approach of yoga intervention modulates the stress and DNA damage levels in breast cancer patients during radiotherapy.
This study examined the effect of an integrated yoga programme on chemotherapy-related nausea and emesis in early operable breast cancer outpatients. Sixty-two subjects were randomly allocated to receive yoga (n = 28) or supportive therapy intervention (n = 34) during the course of their chemotherapy. Both groups had similar socio-demographic and medical characteristics. Intervention consisted of both supervised and home practice of yoga sessions lasting for 60 min daily, while the control group received supportive therapy and coping preparation during their hospital visits over a complete course of chemotherapy. The primary outcome measure was the Morrow Assessment of Nausea and Emesis (MANE) assessed after the fourth cycle of chemotherapy. Secondary outcomes included measures for anxiety, depression, quality of life, distressful symptoms and treatment-related toxicity assessed before and during the course of chemotherapy. Following yoga, there was a significant decrease in post-chemotherapy-induced nausea frequency (P = 0.01) and nausea intensity (P = 0.01), and intensity of anticipatory nausea (P = 0.01) and anticipatory vomiting (P = 0.05) as compared with the control group. There was a significant positive correlation between MANE scores and anxiety, depression and distressful symptoms. In conclusion, the results suggest a possible use for stress reduction interventions such as yoga in complementing conventional antiemetics to manage chemotherapy-related nausea and emesis.
Objectives. This study compares the effects of an integrated yoga program with brief supportive therapy in breast cancer outpatients undergoing adjuvant radiotherapy at a cancer center. Methods. Eighty-eight stage II and III breast cancer outpatients are randomly assigned to receive yoga (n = 44) or brief supportive therapy (n = 44) prior to radiotherapy treatment. Assessments include diurnal salivary cortisol levels 3 days before and after radiotherapy and self-ratings of anxiety, depression, and stress collected before and after 6 weeks of radiotherapy. Results. Analysis of covariance reveals significant decreases in anxiety ( P < .001), depression ( P = .002), perceived stress ( P < .001), 6 a.m. salivary cortisol ( P = .009), and pooled mean cortisol ( P = .03) in the yoga group compared with controls. There is a significant positive correlation between morning salivary cortisol level and anxiety and depression. Conclusion. Yoga might have a role in managing self-reported psychological distress and modulating circadian patterns of stress hormones in early breast cancer patients undergoing adjuvant radiotherapy.
Background:Schizophrenia is a highly disabling illness. Previous studies have shown yoga to be a feasible add-on therapy in schizophrenia.Aims:The current study aimed to test the efficacy of yoga as an add-on treatment in outpatients with schizophrenia.Settings and Design:The study done at a tertiary psychiatry center used a single blind randomized controlled design with active control and waitlist groups.Materials and Methods:Consenting patients with schizophrenia were randomized into yoga, exercise, or waitlist group. They continued to receive pharmacological therapy that was unchanged during the study. Patients in the yoga or exercise group were offered supervised daily procedures for one month. All patients were assessed by a blind rater at the start of the intervention and at the end of 4 months.Results:Kendall tau, a nonparametric statistical test, showed that significantly more patients in the yoga group improved in Positive and Negative Syndrome Scale (PANSS) negative and total PANSS scores as well as social functioning scores compared with the exercise and waitlist group. Odds ratio analysis showed that the likelihood of improvement in yoga group in terms of negative symptoms was about five times greater than either the exercise or waitlist groups.Conclusion:In schizophrenia patients with several years of illness and on stabilized pharmacological therapy, one-month training followed by three months of home practices of yoga as an add-on treatment offered significant advantage over exercise or treatment as usual. Yoga holds promise as a complementary intervention in the management of schizophrenia.
