A randomized controlled trial of qigong for fibromyalgia

Introduction

Fibromyalgia is difficult to treat and requires the use of multiple approaches. This study is a randomized controlled trial of qigong compared with a wait-list control group in fibromyalgia.

Methods

One hundred participants were randomly assigned to immediate or delayed practice groups, with the delayed group receiving training at the end of the control period. Qigong training (level 1 Chaoyi Fanhuan Qigong, CFQ), given over three half-days, was followed by weekly review/practice sessions for eight weeks; participants were also asked to practice at home for 45 to 60 minutes per day for this interval. Outcomes were pain, impact, sleep, physical function and mental function, and these were recorded at baseline, eight weeks, four months and six months. Immediate and delayed practice groups were analyzed individually compared to the control group, and as a combination group.

Results

In both the immediate and delayed treatment groups, CFQ demonstrated significant improvements in pain, impact, sleep, physical function and mental function when compared to the wait-list/usual care control group at eight weeks, with benefits extending beyond this time. Analysis of combined data indicated significant changes for all measures at all times for six months, with only one exception. Post-hoc analysis based on self-reported practice times indicated greater benefit with the per protocol group compared to minimal practice.

Conclusions

This study demonstrates that CFQ, a particular form of qigong, provides long-term benefits in several core domains in fibromyalgia. CFQ may be a useful adjuvant self-care treatment for fibromyalgia.

Proximal gastric vagotomy: interim results of a randomized controlled trial.

In a randomized controlled trial 50 patients with duodenal ulcer treated by proximal gastric vagotomy (P.G.V.) without drainage were compared with 50 who underwent selective vagotomy and gastrojejunostomy. The clinical results were assessed in 99 patients one to four years after operation. Patients who had undergone P.G.V. had significantly less dumping, nausea, and bile vomiting and fared better in their overall clinical grading. The postoperative Visick grading of the 50 patients with P.G.V. was similar to that of 56 controls with no known gastrointestinal disease who had not undergone operation. The results obtained in the patients who had had P.G.V. without drainage were compared with those of a further group of 24 patients subjected of P.G.V. with gastrojejunostomy, and the better results obtained in the former group were thought to be due to elimination of the drainage procedure. The average follow-up period of the trial was just over two years, but there were no indications that the recurrent ulceration rate after P.G.V. would be any higher than after other types of vagotomy and drainage.     

Evaluation of a stroke family care worker: results of a randomised controlled trial.

OBJECTIVE: To examine the effect of contact with a stroke family care worker on the physical, social, and psychological status of stroke patients and their carers. DESIGN: Randomised controlled trial with broad entry criteria and blinded outcome assessment six months after randomisation. SETTING: A well organised stroke service in an Edinburgh teaching hospital. SUBJECTS: 417 patients with an acute stroke in the previous 30 days randomly allocated to be contacted by a stroke family care worker (210) or to receive standard care (207). The patients represented 67% of all stroke patients assessed at the hospital during the study period. MAIN OUTCOME MEASURES: Patient completed Barthel index, Frenchay activities index, general health questionnaire, hospital anxiety and depression scale, social adjustment scale, mental adjustment to stroke scale, and patient satisfaction questionnaire; carer completed Frenchay activities index, general health questionnaire, hospital anxiety and depression scale, social adjustment scale, caregiving bassles scale, and carer satisfaction questionnaire. RESULTS: The groups were balanced for all important baseline variables. There were no significant differences in physical outcomes in patients or carers, though patients in the treatment group were possibly more helpless less well adjusted socially, and more depressed, whereas carers in the treatment group were possibly less hassled and anxious. However, both patients and carers in the group contacted by the stroke family care worker expressed significantly greater satisfaction with certain aspects of their care, in particular those related to communication and support. CONCLUSIONS: The introduction of a stroke family care worker improved patients'' and their carers'' satisfaction with services and may have had some effect on psychological and social outcomes but did not improve measures of patients'' physical wellbeing.     

Management of acute stroke in the elderly: preliminary results of a controlled trial.

A randomised controlled trial compared the management of elderly patients with acute stroke in a stroke unit and medical units. A significantly higher proportion of patients discharged from the stroke unit (78 of the 155 admitted) were assessed as independent compared with patients discharged from medical units (49 of the 152 admitted). The intensive use of treatment that might have been implied by creating a stroke unit did not occur, although almost all the patients admitted to the unit received occupational therapy while only 47% of the patients admitted to medical units received occupational therapy. The delay before starting treatment was significantly shorter in the stroke unit. Results of this trial show that the stroke unit improved the natural history of stroke by increasing the proportion of patients who were returned to functional independence.     

Cost-utility of an 8-month aquatic training for women with fibromyalgia: a randomized controlled trial

Introduction

Physical therapy in warm water has been effective and highly recommended for persons with fibromyalgia, but its efficiency remains largely unknown. Should patients or health care managers invest in this therapy? The aim of the current study was to assess the cost-utility of adding an aquatic exercise programme to the usual care of women with fibromyalgia.

Methods

Costs to the health care system and to society were considered in this study that included 33 participants, randomly assigned to the experimental group (n = 17) or a control group (n = 16). The intervention in the experimental group consisted of a 1-h, supervised, water-based exercise sessions, three times per week for 8 months. The main outcome measures were the health care costs and the number of quality-adjusted life-years (QALYs) using the time trade-off elicitation technique from the EuroQol EQ-5D instrument. Sensitivity analyses were performed for variations in staff salary, number of women attending sessions and time spent going to the pool. The cost effectiveness acceptability curves were created using a non-parametric bootstrap technique.

Results

The mean incremental treatment costs exceeded those for usual care per patient by € 517 for health care costs and € 1,032 for societal costs. The mean incremental QALY associated with the intervention was 0.131 (95% CI: 0.011 to 0.290). Each QALY gained in association with the exercise programme cost an additional € 3,947/QALY (95% CI: 1,782 to 47,000) for a health care perspective and € 7,878/QALY (3,559 to 93,818) from a societal perspective. The curves showed a 95% probability that the addition of the water-based programme is a cost-effective strategy if the ceiling of inversion is € 14,200/QALY from a health care perspective and € 28,300/QALY from a societal perspective.

Conclusion

The addition of an aquatic exercise programme to the usual care regime for fibromyalgia in women is cost effective in terms of both health care costs and societal costs. However, the characteristics of facilities (distance from the patients' homes and number of patients that can be accommodated per session) are major determinants to consider before investing in such a programme.

Chemotherapy in pancreatic cancer: results of a controlled,prospective, randomised,multicentre trial.

Forty patients with inoperable pancreatic cancer were included in a prospective, randomised, controlled trial of multiple chemotherapy. The survival of 19 untreated control patients was compared with that of 21 patients who received an initiation course of intravenous fluorouracil, cyclophosphamide, methotrexate, and vincristine given over five days followed by intravenous fluorouracil and mitomycin given over three or five days at six-week intervals thereafter. Median survival in treated patients was 44 weeks, which was significantly longer than the nine weeks seen in controls. In patients without metastases median survival was 48 weeks in the treated group and 12 weeks in controls. In patients with metastases it was 30 weeks in treated patients and seven weeks in controls. The treatment was well tolerated and seemed to confer a significant prolongation of survival, comparing favourably with previous reports of chemotherapy with or without radiotherapy. If the results are confirmed this regimen may be useful in district general hospital practice.     

Cost effectiveness of day and inpatient psychiatric treatment: results of a randomised controlled trial.

OBJECTIVE: To compare direct and indirect costs of day and inpatient treatment of acute psychiatric illness. DESIGN: Randomised controlled trial with outcome and costs assessed over 12 months after the date of admission. SETTING: Teaching hospital in an inner city area. SUBJECTS: 179 patients with acute psychiatric illness referred for admission who were suitable for random allocation to day hospital or inpatient treatment. 77 (43%) patients had schizophrenia. INTERVENTIONS: Routine inpatient or day hospital treatment. MAIN OUTCOME MEASURES: Direct and indirect costs over 12 months, clinical symptoms, social functioning, and burden on relatives over the follow up period. RESULTS: Clinical and social outcomes were similar at 12 months, except that inpatients improved significantly faster than day patients and burden on relatives was significantly less in the day hospital group at one year. Median direct costs to the hospital were 1923 pounds (95% confidence interval 750 pounds to 3174 pounds) per patient less for day hospital treatment than inpatient treatment. Indirect costs were greater for day patients; when these were included, overall day hospital treatment was 2165 pounds cheaper than inpatient treatment (95% confidence interval of median difference 737 pounds to 3593 pounds). Including costs to informants when appropriate meant that day hospital treatment was 1994 pounds per patient cheaper (95% confidence interval 600 pounds to 3543 pounds). CONCLUSIONS: Day patient treatment is cheaper for the 30-40% of potential admissions that can be treated in this way. Carers of day hospital patients may bear additional costs. Carers of all patients with acute psychiatric illness are often themselves severely distressed at the time of admission, but day hospital treatment leads to less burden on carers in the long term.     

Effectiveness of cognitive behaviour therapy for the treatment of catastrophisation in patients with fibromyalgia: a randomised controlled trial

Introduction  

No randomised, controlled trials have been conducted to date on the efficacy of psychological and pharmacological treatments of pain catastrophising (PC) in patients with fibromyalgia. Our aim in this study was to assess the effectiveness of cognitive-behaviour therapy (CBT) and the recommended pharmacological treatment (RPT) compared with treatment as usual (TAU) at the primary care level for the treatment of PC in fibromyalgia patients.     

Preoperative lifestyle intervention in bariatric surgery: Initial results from a randomized,controlled trial

Objective:

To document preoperative outcomes of a behavioral lifestyle intervention delivered to patients prior to bariatric surgery in comparison to treatment as usual (insurance‐mandated physician supervised diet).

Design and Methods:

After completing a baseline assessment, candidates for surgery were randomized to a 6‐month, evidence‐informed, manualized lifestyle intervention (LIFESTYLE, n = 121) or to preoperative care as usual (USUAL CARE, n = 119). At 6 months, 187 participants remained candidates for bariatric surgery and were included in the analyses.

Results:

LIFESTYLE participants lost significantly more weight than those receiving USUAL CARE [8.3 ± 7.8 kg vs. 3.3 ± 5.5 kg, F(1,183) = 23.6, P < 0.0001], with an effect size of 0.72. Additionally, logistic regression modeling indicated that LIFESTYLE patients were significantly more likely to lose at least 5% of initial body weight than those in USUAL CARE [OR (95% CI) = 2.94 (1.253, 6.903)], as were participants who were heavier [OR (95% CI) = 1.07 (1.001‐1.14) for each unit increase in BMI] or with larger improvements in eating behaviors [OR (95% CI) = 1.1 (1.049, 1.145) for each unit increase on the Eating Behavior Inventory).

Conclusions:

A behavioral lifestyle intervention for severely overweight individuals leads to clinically significant weight loss prior to bariatric surgery. Post‐surgery follow‐up will allow us to examine the impact of the preoperative intervention on postoperative outcomes.     

Electric convulsion therapy in depression: a double-blind controlled trial.

The therapeutic effect of simulated and real bilateral electric convulsion therapy was examined in a double-blind, randomised trial on 22 patients with a primary depressive illness. Each treatment was given twice weekly for three weeks and the results assessed by the psychiatrist using a visual analogue rating scale, nurses using a nine-point rating scale, and the patients themselves using the Beck Depression Inventory. With all three methods of assessment patients given the real treatment substantially improved (p less than 0.001), whereas those given simulated treatment showed little change. Three weeks after substituting real treatment for simulated, however, these patients were also significantly improved (psychiatrist''s rating p less than 0.001; nurses'' rating p less than 0.005; Beck inventory p less than 0.005). These findings confirm the value of electric convulsion therapy in severe depressive illness and strongly suggest that the convulsion is important for the therapeutic effect.     

Effects of lifestyle physical activity on perceived symptoms and physical function in adults with fibromyalgia: results of a randomized trial

Introduction  

Although exercise is therapeutic for adults with fibromyalgia (FM), its symptoms often create obstacles that discourage exercise. We evaluated the effects of accumulating at least 30 minutes of self-selected lifestyle physical activity (LPA) on perceived physical function, pain, fatigue, body mass index, depression, tenderness, and the six-minute walk test in adults with FM.     

Bone resorption is induced on the second day of bed rest: results of a controlled crossover trial.

The aim of the study was to analyze the kinetics of short-term changes in bone turnover. We studied in a randomized crossover design the effects of 6 days of bed rest on eight healthy male subjects (mean body wt: 70.1 +/- 5.7 kg; mean age: 25.5 +/- 2.9 yr). The metabolic ward period was divided into three parts: 4 ambulatory days, 6 days of either bed rest or non-bed rest periods, and 1 recovery day. The diet was identical in both bed rest and non-bed rest phases. Continuous urine collection started on the first day in the metabolic ward to analyze excretion of bone resorption markers, namely C-telopeptide (CTX) and N-telopeptide (NTX), creatinine, urea, and 3-methylhistidine. On the second ambulatory day and on the fifth day of bed rest or during the non-bed rest phase, blood was drawn to analyze bone formation markers and amino acid concentrations. Urinary calcium excretion was increased as early as the first day of bed rest (P < 0.01). CTX and NTX excretion stayed unchanged during the first 24 h of bed rest compared with the non-bed rest period. However, already on the second day, both resorption markers had increased significantly. NTX excretion increased by 28.7 +/- 14.0% (P < 0.01), whereas CTX excretion rose by 17.8 +/- 8.3% (P < 0.001). Creatinine, urea, and 3-methylhistidine excretion did not change. We conclude that 24 h of bed rest are sufficient to induce a significant rise in osteoclast activity in healthy subjects.     

Continuing efficacy of milnacipran following long-term treatment in fibromyalgia: a randomized trial

Introduction

Previous studies of long-term treatment response in fibromyalgia and other chronic pain states have generally been limited to approximately one year, leaving questions about the longer-term durability of response. The purpose of this study was to demonstrate continuing efficacy of milnacipran by characterizing changes in pain and other fibromyalgia symptoms after discontinuing long-term treatment. The mean length of milnacipran treatment at the time of randomized withdrawal was 36.1 months from initial exposure to milnacipran (range, 17.9 to 54.4 months).

Methods

After completing a long-term, open-label, lead-in study of milnacipran (which followed varying periods of exposure in previous studies), adult patients with fibromyalgia entered the four-week open-label period of the current study for evaluation of ongoing treatment response. After the four-week period to confirm new baseline status, 151 patients taking milnacipran ≥100 mg/day and reporting ≥50% improvement from pre-milnacipran exposure in Visual Analogue Scale (VAS) pain scores were classified as responders. These responders entered the 12-week, double-blind withdrawal period in which they were randomized 2:1 to continue milnacipran or switched to placebo. The prespecified primary parameter was loss of therapeutic response (LTR), defined as increase in VAS pain score to <30% reduction from pre-milnacipran exposure or worsening of fibromyalgia requiring alternative treatment. Adverse events and vital signs were also monitored.

Results

Time to LTR was shorter in patients randomized to placebo than in patients continuing milnacipran (P < 0.001). Median time to LTR was 56 days with placebo and was not calculable for milnacipran, because less than half of the latter group of patients lost therapeutic response by study end. Additionally, 81% of patients continuing on milnacipran maintained clinically meaningful pain response (≥30% improvement from pre-milnacipran exposure), compared with 58% of patients switched to placebo (sensitivity analysis II; P < 0.001). The incidences of treatment-emergent adverse events were 58% and 47% for placebo and milnacipran, respectively. Mean decreases in blood pressure and heart rate were found in both groups, with greater decreases for patients switched to placebo.

Conclusions

Continuing efficacy of milnacipran was demonstrated by the loss of effect following withdrawal of treatment in patients who received an average of three years of milnacipran treatment.

Remedial therapy after stroke: a randomised controlled trial.

Of 1094 patients with a confirmed stroke admitted to Northwick Park, a district general hospital, 364 (33%) died while in hospital, 215 (20%) were fully recovered when discharged, and 329 (30%) were too frail or too ill from diseases other than stroke to be considered for active rehabilitation. Only 121 (11%) were suitable for intensive treatment. They and 12 patients referred direct to outpatients were allocated at random to one of three different courses of rehabilitation. Intensive was compared with conventional rehabilitation and with a third regimen which included no routine rehabilitation, but under which patients were encouraged to continue with exercises taught while in hospital and were regularly seen at home by a health visitor. Progress at three months and 12 months was measured by an index of activities of daily living. Improvement was greatest in those receiving intensive treatment, intermediate in those receiving conventional treatment, and least in those receiving no routine treatment. Decreasing intensity of treatment was associated with a significant increase in the proportions of patients who deteriorated and in the extent to which they deteriorated. Probably only a few stroke patients, mostly men, are suitable for intensive outpatient rehabilitation, but for those patients the treatment is effective and realistic.     

Care in a birth room versus a conventional setting: a controlled trial.

A controlled clinical trial was carried out to assess whether a birth room setting would influence the care of mothers and newborns. Of the 163 low-risk women enrolled, 49 (30%) manifested some prenatal risk and were excluded. The remaining 114 were allocated by strict alternation to a birth room or a conventional setting. Of the 56 women allocated to the birth room, 63% of the primiparas and 19% of the multiparas were later transferred. The numbers in the two settings who had oxytocin stimulation, epidural anesthesia, forceps delivery or cesarean section did not show statistically significant differences. The episiotomy rates were slightly lower in the birth room than in the conventional setting, and the rates of an intact perineum were higher in the birth room. Neither the Apgar scores nor the morbidity rates of the infants showed statistically significant differences related to the setting to which the mother had been allocated, although more infants from the conventional setting were admitted to a special care unit. Both "experimental" groups of women less often received routine perineal shaving, enemas or intravenous infusions than did an obstetrically similar nonexperimental comparison group. Despite the apparent inability in this setting for the birth room to influence the rate of major obstetric procedures (except for episiotomy) and outcomes, the authors believe that a birth room is desirable in tertiary care centres as well as in community hospitals.     

Cimetidine in patients with gastric ulcer: a multicentre controlled trial.

Forty-five adult outpatients with endoscopically confirmed gastric ulceration completed a double-blind trial of either cimetidine (1 g/day) or placebo. After six weeks 18 of the 23 patients receiving cimetidine showed complete ulcer healing compared with only six of the 22 patients receiving placebo. The cimetidine group also had fewer days with pain than the placebo group but the difference was not statistically significant. Cimetidine therefore seems to promote healing of gastric ulcers without severe side effects, although its effect on pain is less pronounced than in patients with duodenal ulcers.     

Streptokinase in central retinal vein occlusion: a controlled clinical trial.

Forty patients with central retinal vein occlusion were allocated at random either to a treatment group given streptokinase followed by anticoagulatns or to a control group given no specific treatment. The two groups, which were each of 20 patients, were broadly similar in respect of clinical and laboratory values and similar in their initial visual acuity. At follow-up ("final" vision) the visual acuity in the treated group was significantly better than in the untreated group. Only one treated patient developed thrombotic glaucoma compared with four controls. Streptokinase may, however, have been responsible for vitreous haemorrhage (and permanent loss of vision) in three patients and hence probably has only a limited role in the treatment of central retinal vein occlusion.     

Heart disease prevention project: a randomised controlled trial in industry.

Twenty-four factories or other occupational groups, employing 18 210 men aged 40 to 59, were formed into matched pairs. One of each pair was allocated randomly to receive a five to six year programme of medical examinations and intervention to reduce the levels of the main coronary risk factors. Men at factories in the intervention group were given advice on dietary reduction of plasma cholesterol concentrations, stopping or reducing cigarette smoking, regular exercies for the sedentary and reduced energy intake for the overweight, and hypertension was treated. The programme was delivered mainly through existing occupational medical services, helped by a small central staff. Personal consultations were largely confined to men with a high risk of developing coronary heart disease. Changes in risk factors were assessed by regular standardised examinations of random samples of men. The spread of information by general propaganda proved easy, but a change in habits seemed to require personal contact. Small but significant reductions occurred, mainly in the high-risk group, but these were not sustained when pressure was relaxed.     

Effect of four days of preoperative lactulose on posthaemorrhoidectomy pain: results of placebo controlled trial.

The effect of four days of preoperative lactulose on posthaemorrhoidectomy pain was studied in a prospective double blind randomized trial. All patients received lactulose on admission to hospital, 20 received lactulose for four days before admission, and 22 received placebo. The preoperative lactulose treatment group suffered significantly less pain on defecation for the first four days that they opened their bowels (visual analogue scores in cm: day 1, 4.4 v 5.9; day 2, 4.1 v 6.3; day 3, 4.5 v 6.1; day 4, 4.6 v 6.5), suffered significantly less pain during the first two 24 hour periods after defecation (visual analogue scores in cm: day 1, 5.0 v 7.0; day 2, 3.9 v 6.1), and required significantly less analgesia daily after defecation (0.76 g paracetamol/day v 1.29 g paracetamol/day). These results show that lactulose given for four days preoperatively reduces pain after haemorrhoidectomy.
