Prospective randomised controlled trial of methods of call and recall for cervical cytology screening.

OBJECTIVE--To discover whether systematic methods of call and recall are more effective than a non-systematic method and to see which of the two systematic methods was more effective. DESIGN--Prospective randomised controlled trial over a year. SETTING--One group general practice. PATIENTS--416 Women over 35 eligible for a smear test who had never had a cervical smear test or in whom a smear test was overdue (previous test more than five years before). INTERVENTIONS--One group received written invitations to have a smear taken. The second group had their notes tagged so that the doctor would remind them (when they attended for another reason) to have a smear test. No special intervention was made in the third group. MAIN OUTCOME MEASURE--Performance of a cervical smear test during the year of the study. RESULTS--32% (45/140) of the screened group, 27% (39/142) of the tagged group, and 15% (20/134) of the control group had a smear test during the year. The percentage of women having a smear test in the screened group was not significantly different from that in the tagged group, but the percentages in the two groups were significantly different from that in the control group. Whether a woman had had a previous smear test significantly affected the uptake of the invitation to have a smear test independently of the method of invitation. CONCLUSIONS--The systematic methods of call and recall were more effective than a non-systematic method. There was no significant difference between the two systematic methods (sending letters or tagging the notes) at one year.     

Effectiveness of massage therapy for subacute low-back pain: a randomized controlled trial

BACKGROUND: The effectiveness of massage therapy for low-back pain has not been documented. This randomized controlled trial compared comprehensive massage therapy (soft-tissue manipulation, remedial exercise and posture education), 2 components of massage therapy and placebo in the treatment of subacute (between 1 week and 8 months) low-back pain. METHODS: Subjects with subacute low-back pain were randomly assigned to 1 of 4 groups: comprehensive massage therapy (n = 25), soft-tissue manipulation only (n = 25), remedial exercise with posture education only (n = 22) or a placebo of sham laser therapy (n = 26). Each subject received 6 treatments within approximately 1 month. Outcome measures obtained at baseline, after treatment and at 1-month follow-up consisted of the Roland Disability Questionnaire (RDQ), the McGill Pain Questionnaire (PPI and PRI), the State Anxiety Index and the Modified Schober test (lumbar range of motion). RESULTS: Of the 107 subjects who passed screening, 98 (92%) completed post-treatment tests and 91 (85%) completed follow-up tests. Statistically significant differences were noted after treatment and at follow-up. The comprehensive massage therapy group had improved function (mean RDQ score 1.54 v. 2.86-6.5, p < 0.001), less intense pain (mean PPI score 0.42 v. 1.18-1.75, p < 0.001) and a decrease in the quality of pain (mean PRI score 2.29 v. 4.55-7.71, p = 0.006) compared with the other 3 groups. Clinical significance was evident for the comprehensive massage therapy group and the soft-tissue manipulation group on the measure of function. At 1-month follow-up 63% of subjects in the comprehensive massage therapy group reported no pain as compared with 27% of the soft-tissue manipulation group, 14% of the remedial exercise group and 0% of the sham laser therapy group. INTERPRETATION: Patients with subacute low-back pain were shown to benefit from massage therapy, as regulated by the College of Massage Therapists of Ontario and delivered by experienced massage therapists.     

Randomised trial of compliance with screening for colorectal cancer.

A randomised trial of compliance with screening for colorectal cancer by means of the haemoccult test was conducted in Farnborough and Basingstoke districts. In each of the 14 participating practices (41 general practitioners) 25 852 men and women aged between 40 and 70 years were randomly allocated by household to one of six groups. The group determined the method of invitation to screening: a letter and the test were sent to the patient, or a letter with an appointment to attend the surgery was sent, or during a routine consultation the general practitioner invited patients to participate, and some patients received an educational booklet about bowel disorders and screening. Of the 17 824 people who were offered screening, 7545 (42%) complied. Compliance was significantly affected by the method of invitation, but not by whether an educational booklet was received, and was highest (57%) in the group that was offered the haemoccult test during a routine consultation (the "opportunistic" approach). In this group the compliance rate achieved by individual general practitioners ranged from 26% to 82%. Compliance was significantly higher in Farnborough, in the older (55-70) age group, in women, and in households in which two or more people were offered screening. The higher compliance in Farnborough may be explained by the higher proportion of older people and by the higher proportion of people living in households of two or more in the population that was offered screening. The fact that the screening programme in Farnborough was offered to the whole community and that the researcher may have acted as a facilitator were probably also important. One per cent of the patients screened had a positive test, and 24 (38%) of the 63 patients who were positive and were investigated in hospital had neoplastic disease. The yield was 1.2 cancers and 1.2 benign adenomas (1 cm or larger in size) per 1000 people screened. This low yield is likely to be a consequence of the relatively young age group screened.     

Efficacy of an educational material on second primary cancer screening practice for cancer survivors: a randomized controlled trial

Background

Cancer surivors have limited knowledge about second primary cancer (SPC) screening and suboptimal rates of completion of screening practices for SPC. Our objective was to test the efficacy of an educational material on the knowledge, attitudes, and screening practices for SPC among cancer survivors.

Methods

Randomized, controlled trial among 326 cancer survivors from 6 oncology care outpatient clinics in Korea. Patients were randomized to an intervention or an attention control group. The intervention was a photo-novel, culturally tailored to increase knowledge about SPC screening. Knowledge and attitudes regarding SPC screening were assessed two weeks after the intervention, and screening practices were assessed after one year.

Results

At two weeks post-intervention, the average knowledge score was significantly higher in the intervention compared to the control group (0.81 vs. 0.75, P<0.01), with no significant difference in their attitude scores (2.64 vs. 2.57, P = 0.18). After 1 year of follow-up, the completion rate of all appropriate cancer screening was 47.2% in both intervention and control groups.

Conclusion

While the educatinal material was effective for increasing knowledge of SPC screening, it did not promote cancer screening practice among cancer survivors. More effective interventions are needed to increase SPC screening rates in this population.

A multi-centre randomized controlled trial of rehabilitation aimed at improving outdoor mobility for people after stroke: study protocol for a randomized controlled trial

ABSTRACT: BACKGROUND: Up to 42% of all stroke patients do not get out of the house as much as they would like. This can impede a person's quality of life. This study is testing the clinical effectiveness and cost effectiveness of a new outdoor mobility rehabilitation intervention by comparing it to usual care. METHODS: Multi-centre parallel group individually randomised controlled trial. At least 506 participants will be recruited through 15 primary and secondary care settings and will be eligible if they are over 18 years of age, have had a stroke and wish to get out of the house more often. Participants are being randomly allocated to either the intervention group or the control group. Intervention group participants receive up to 12 rehabilitation outdoor mobility sessions over up to 4 months. The main component of the intervention is repeated practice of outdoor mobility with a therapist. Control group participants are receiving the usual intervention for outdoor mobility limitations: verbal advice and provision of leaflets provided over one session. Outcome measures are being collected using postal questionnaires, travel calendars and by independent assessors. The primary outcome measure is the Social Function domain of the SF36v2 quality of life assessment six months after recruitment. The secondary outcome measures include: functional ability, mobility, the number of journeys (monthly travel diaries), satisfaction with outdoor mobility, mood, health-related quality of life, resource use of health and social care. Carer mood is also being collected. The mean Social Function score of the SF-36v2 will be compared between treatment arms using a multiple membership form of mixed effects multiple regression analysis adjusting for centre (as a fixed effect), age and baseline Social Function score as covariates and therapist as a multiple membership random effect. Regression coefficients and 95% confidence intervals will be presented. DISCUSSION: This study protocol describes a pragmatic randomised controlled trial that will hopefully provide robust evidence of the benefit of outdoor mobility interventions after stroke for clinicians working in the community. The results will be available towards the end of 2012.     

Understanding and enhancing compliance with the second dose of hepatitis B vaccine: a cohort analysis and a randomized controlled trial

OBJECTIVE: To determine the predictors and extent of noncompliance with a second dose of hepatitis B vaccine and the effectiveness of a compliance enhancement strategy. DESIGN: Cohort analysis and randomized clinical trial. SUBJECTS: A total of 256 consecutive adults attending a sexually transmitted diseases clinic from October 1992 to July 1993 who were seronegative for hepatitis B virus and agreed to receive hepatitis B vaccination. SETTING: Hamilton, Ont. INTERVENTION: Subjects were followed up for 4 months. Those who did not return for the second dose of vaccine by 6 weeks after the first (2 weeks overdue) were randomly assigned to the enhanced intervention group (telephone and mail reminders) or the regular intervention group (mail reminder only). Subjects were considered noncompliant if they did not return for the second dose by 4 months after the first. RESULTS: The risk of not returning for the second dose of vaccine within 4 months after the first was strongly and linearly associated with level of education (p = 0.004). The noncompliance rate among those with less than a grade 10 education was 50%, grade 10-13 education 34%, some college education 15% and some university education 9%. In the randomized controlled trial the enhanced intervention group had twice the compliance rate of the regular intervention group (48% v. 25%; p = 0.008). Subjects with no postsecondary education were highly responsive to the enhanced intervention (relative risk 2.1; p = 0.02) compared with those with a higher level of education (relative risk 1.0; p = 1.0). CONCLUSION: Hepatitis B vaccine recipients with lower educational levels are at increased risk of noncompliance with the second dose of vaccine but are highly responsive to telephone reminders.     

Effectiveness of enhanced cognitive behavior therapy for bulimia nervosa in Japan: a randomized controlled trial protocol

Although fatigue is a common and distressing symptom in cancer survivors, the mechanism of fatigue is not fully understood. Therefore, this study aims to investigate the relation between the fatigue and mindfulness of breast cancer survivors using anxiety, depression, pain, loneliness, and sleep disturbance as mediators. Path analysis was performed to examine direct and indirect associations between mindfulness and fatigue. Participants were breast cancer survivors who visited a breast surgery department at a university hospital in Japan for hormonal therapy or regular check-ups after treatment. The questionnaire measured cancer-related-fatigue, mindfulness, anxiety, depression, pain, loneliness, and sleep disturbance. Demographic and clinical characteristics were collected from medical records. Two-hundred and seventy-nine breast cancer survivors were registered, of which 259 answered the questionnaire. Ten respondents with incomplete questionnaire data were excluded, resulting in 249 participants for the analyses. Our final model fit the data well (goodness of fit index = .993; adjusted goodness of fit index = .966; comparative fit index = .999; root mean square error of approximation = .016). Mindfulness, anxiety, depression, pain, loneliness, and sleep disturbance were related to fatigue, and mindfulness had the most influence on fatigue (β = − .52). Mindfulness affected fatigue not only directly but also indirectly through anxiety, depression, pain, loneliness, and sleep disturbance. The study model helps to explain the process by which mindfulness affects fatigue. Our results suggest that mindfulness has both direct and indirect effects on the fatigue of breast cancer survivors and that mindfulness can be used to more effectively reduce their fatigue. It also suggests that health care professionals should be aware of factors such as anxiety, depression, pain, loneliness, and sleep disturbance in their care for fatigue of breast cancer survivors. This study was registered in the University Hospital Medical Information Network Clinical Trials Registry (UMIN number. 000027720) on June 12, 2017.     

Effectiveness of smoking-cessation interventions for urban hospital patients: study protocol for a randomized controlled trial

ABSTRACT: BACKGROUND: Hospitalization may be a particularly important time to promote smoking cessation, especially in the immediate post-discharge period. However, there are few studies to date that shed light on the most effective or cost-effective methods to provide post-discharge cessation treatment, especially among low-income populations and those with a heavy burden of mental illness and substance use disorders. METHODS: This randomized trial will compare the effectiveness and cost-effectiveness of two approaches to smoking cessation treatment among patients discharged from two urban public hospitals in New York City. During hospitalization, staff will be prompted to ask about smoking and to offer nicotine replacement therapy (NRT) on admission and at discharge. Subjects will be randomized on discharge to one of two arms: One arm will be proactive multi-session telephone counseling with motivational enhancement delivered by study staff, and the other will be a faxed or online referral to the New York State Quitline. The primary outcome is 30-day point-prevalence abstinence from smoking at 6-month follow-up post-discharge. We will also examine cost-effectiveness from a societal and a payer perspective, as well as explore subgroup analyses related to patients' location of hospitalization, race/ethnicity, immigrant status, and inpatient diagnosis. DISCUSSION: This study will explore issues of implementation feasibility in a post-hospitalization patient population, as well as add information about the effectiveness and cost-effectiveness of different strategies for designing smoking cessation programs for hospitalized patients.     

Effectiveness of a home-based balance-training program in reducing sports-related injuries among healthy adolescents: a cluster randomized controlled trial

Background

Sport is the leading cause of injury requiring medical attention among adolescents. We studied the effectiveness of a home-based balance-training program using a wobble board in improving static and dynamic balance and reducing sports-related injuries among healthy adolescents.

Methods

In this cluster randomized controlled trial, we randomly selected 10 of 15 high schools in Calgary to participate in the fall of 2001. We then recruited students from physical education classes and randomly assigned them, by school, to either the intervention (n = 66) or the control (n = 61) group. Students in the intervention group participated in a daily 6-week and then a weekly 6-month home-based balance-training program using a wobble board. Students at the control schools received testing only. The primary outcome measures were timed static and dynamic balance, 20-m shuttle run and vertical jump, which were measured at baseline and biweekly for 6 weeks. Self-reported injury data were collected over the 6-month follow-up period.

Results

At 6 weeks, improvements in static and dynamic balance were observed in the intervention group but not in the control group (difference in static balance 20.7 seconds, 95% confidence interval [CI] 10.8 to 30.6 seconds; difference in dynamic balance 2.3 seconds, 95% CI 0.7 to 4.0 seconds). There was evidence of a protective effect of balance training in over 6 months (relative risk of injury 0.2, 95% CI 0.05 to 0.88). The number needed to treat to avoid 1 injury over 6 months was 8 (95% CI 4 to 35).

Interpretation

Balance training using a wobble board is effective in improving static and dynamic balance and reducing sports-related injuries among healthy adolescents.Adolescents commonly participate in sports.^1,2 In a survey of adolescents in Alberta, 59% reported that they took part in sports more than 5 hours per week (unpublished data). In North America, sport is the leading cause of injury requiring medical attention and visits to an emergency department among adolescents.^3,4 In Alberta 26% of youths aged 15–19 years in a survey reported sustaining a sports-related injury requiring medical attention.⁵ The impact may be lifelong, as there is evidence that knee and ankle injuries may result in an increased risk of osteoarthritis later in life.^6,7,8 In addition, each year 8% of adolescents drop out of sports activities because of injury.⁹ The reduction in physical activity resulting from sports-related injuries could have significant long-term effects on morbidity and mortality.^10,11Proprioceptive balance training is used in rehabilitation following sports-related injuries and is becoming recognized as an important element in injury prevention in sports.^{12,13,14,15,16,17,18,19} Running, jumping or pivoting on one leg relies on a sense of joint position and muscular control for joint stability. There is evidence that static balance improves following proprioceptive balance training using a wobble board.^20,21,22,23 However, most of these studies did not examine the effect of dynamic proprioceptive balance training, which may improve postural control in athletic situations and prevent some injuries.There is evidence from randomized trials that multifaceted prevention programs, including proprioceptive balance training using a wobble board, are effective in reducing injuries to the lower extremities in specific sports.^{12,13,14,15,16,17,18,19} However, the programs in these trials were multifaceted (i.e., included warm-up, flexibility, jump training, strength training, rehabilitation and sport-specific technical components), and balance was not measured. The effectiveness of balance training alone on balance ability and prevention of injury remains unclear. Moreover, the use of these techniques in adolescents and non-elite athletes has not been studied.The objectives of our study were to determine the effectiveness of a proprioceptive home-based balance-training program in improving static and dynamic balance in adolescents and to examine the effectiveness of this training program on reducing sports-related injury among adolescents.     

Effectiveness of strengthened stimulation during acupuncture for the treatment of Bell palsy: a randomized controlled trial

Background:

The traditional Chinese theory of acupuncture emphasizes that the intensity of acupuncture must reach a threshold to generate de qi, which is necessary to achieve the best therapeutic effect. De qi is an internal compound sensation of soreness, tingling, fullness, aching, cool, warmth and heaviness, and a radiating sensation at and around the acupoints. However, the notion that de qi must be achieved for maximum benefit has not been confirmed by modern scientific evidence.

Methods:

We performed a prospective multicentre randomized controlled trial involving patients with Bell palsy. Patients were randomly assigned to the de qi (n = 167) or control (n = 171) group. Both groups received acupuncture: in the de qi group, the needles were manipulated manually until de qi was reached, whereas in the control group, the needles were inserted without any manipulation. All patients received prednisone as a basic treatment. The primary outcome was facial nerve function at month 6. We also assessed disability and quality of life 6 months after randomization.

Results:

After 6 months, patients in the de qi group had better facial function (adjusted odds ratio [OR] 4.16, 95% confidence interval [CI] 2.23–7.78), better disability assessment (differences of least squares means 9.80, 95% CI 6.29–13.30) and better quality of life (differences of least squares means 29.86, 95% CI 22.33–37.38). Logistic regression analysis showed a positive effect of the de qi score on facial-nerve function (adjusted OR 1.07, 95% CI 1.04–1.09).

Interpretation:

Among patients with Bell palsy, acupuncture with strong stimulation that elicited de qi had a greater therapeutic effect, and stronger intensity of de qi was associated with the better therapeutic effects. Trial registration: Clinicaltrials.gov no. NCT00685789.The use of acupuncture has gained increasing attention worldwide.^1,2 There is a long-held belief in the traditional theory and clinical practice of acupuncture that the intensity of the stimulus must reach a threshold to elicit de qi, which plays a pivotal role in achieving the best therapeutic effects.^3,4De qi — an internal compound sensation of soreness, tingling, fullness, aching, cool, warmth, heaviness and a radiating sensation at and around acupoints — is elicited by manipulation of the needles (rotated as well as being moved upward and downward).⁵ The concept of de qi, originating from the long-term accumulation of clinical experiences, has been explained to some degree by several scientific studies.^6–11 However, this long-held belief has not been confirmed by sufficient evidence from randomized controlled trials.⁵ Consequently, de qi and its related techniques have been neglected in acupuncture practice and research. As such, the therapeutic effects of acupuncture may be seriously compromised.^12–14In this study, we compared the efficacy of acupuncture with either strong (intended to elicit de qi) or weak stimulation among patients with Bell palsy.     

Effect of phototherapy on oxidant/antioxidant status: a randomized controlled trial

In order to evaluate the effect of different types of phototherapy on oxidant/antioxidant status in hyperbilirubinemic neonates, an interventional randomized control trial was conducted on 120 neonates ≥35 weeks’ gestational age with indirect hyperbilirubinemia reaching phototherapy level. This study is registered with ClinicalTrials.gov as NCT03074292. Neonates were assigned to three groups; 40 neonates received conventional phototherapy, 40 received intensive phototherapy and 40 received blue light-emitting diodes (LED) phototherapy. Complete blood count (CBC), total serum bilirubin (TSB), total antioxidant capacity (TAC), malondialdehyde (MDA), nitric oxide (NO), copper (Cu), zinc (Zn), and iron (Fe) levels were measured before and 24?hours after phototherapy. TSB decreased postphototherapy in all three groups (p < .05 for all), with significantly lower levels following intensive and LED phototherapy compared to conventional phototherapy (p < .05 for both). TAC decreased postphototherapy in the three groups (p < .05 for all). MDA and NO increased postphototherapy (p < .05 for all), with the intensive phototherapy group having the highest levels followed by the conventional while LED phototherapy group showed the lowest levels in comparison to the other groups (p < .05). Cu, Zn and Fe increased postphototherapy in all three groups (p < .05 for all). Positive correlations were found between postphototherapy TSB with TAC, Cu and Zn (p < .05) and negative correlations with MDA, NO and Fe (p < .05) among neonates of the 3 studied groups. In conclusion, different photo therapies have an impact on oxidant/antioxidant balance and are associated with increased oxidative stress markers with the LED phototherapy being the safest.     

Nonparametric estimation of asymptomatic duration from a randomized prospective cancer screening trial

We propose a nonparametric estimation of preclinical duration distribution in cancer based on data from a randomized early detection trial. In cancer screening studies, the preclinical duration of a disease is of great interest for better understanding the natural history of the disease, and for developing optimal screening strategies. To estimate the sojourn time distribution nonparametrically, we first estimate the distribution of the age at onset of preclinical disease nonparametrically using data from the screening arm in a randomized screening trial, and the distribution for the age at onset of clinical disease from the control arm of the randomized screening trial. Finally, by using deconvolution the two estimated distributions lead to a nonparametric estimate of the distribution for the gap time between the onset of preclinical disease and the onset of clinical disease. We illustrate the methodology using data from a randomized breast cancer screening trial.     

Therapy of tungiasis: a double-blinded randomized controlled trial with oral ivermectin

Tungiasis is an ectoparasitosis causing considerable pathology in endemic areas. Standard therapy consists of removing the embedded parasite with a sterile needle. There is no effective chemotherapy at hand. To fill this gap, a double-blinded randomized controlled trial with oral ivermectin was conducted. A total of 54 individuals (27 in the placebo group, 27 in the ivermectin group) was followed up for seven days. They presented a total of 192 lesions. Patients received either ivermectin (300 microg/kg body weight at a single dose, repeated after 24 h) or placebo. Outcome measures included the clinical stage of lesion, presence of erythema, pain, itching, signs of viability of the parasite, and total lysis of flea. The ratio of fleas with total lysis per total number of fleas was slightly higher in the ivermectin group; however, this difference was not statistically significant. There was no significant difference in any of the other outcome measures between the treatment and the placebo group. The results show that oral ivermectin is without any clinically significant efficacy against embedded sand fleas at the dose given.     

Acupuncture for migraine prophylaxis: a randomized controlled trial

Background:

Acupuncture is commonly used to treat migraine. We assessed the efficacy of acupuncture at migraine-specific acupuncture points compared with other acupuncture points and sham acupuncture.

Methods:

We performed a multicentre, single-blind randomized controlled trial. In total, 480 patients with migraine were randomly assigned to one of four groups (Shaoyang-specific acupuncture, Shaoyang-nonspecific acupuncture, Yangming-specific acupuncture or sham acupuncture [control]). All groups received 20 treatments, which included electrical stimulation, over a period of four weeks. The primary outcome was the number of days with a migraine experienced during weeks 5–8 after randomization. Our secondary outcomes included the frequency of migraine attack, migraine intensity and migraine-specific quality of life.

Results:

Compared with patients in the control group, patients in the acupuncture groups reported fewer days with a migraine during weeks 5–8, however the differences between treatments were not significant (p > 0.05). There was a significant reduction in the number of days with a migraine during weeks 13–16 in all acupuncture groups compared with control (Shaoyang-specific acupuncture v. control: difference –1.06 [95% confidence interval (CI) –1.77 to –0.5], p = 0.003; Shaoyang-nonspecific acupuncture v. control: difference –1.22 [95% CI –1.92 to –0.52], p < 0.001; Yangming-specific acupuncture v. control: difference –0.91 [95% CI –1.61 to –0.21], p = 0.011). We found that there was a significant, but not clinically relevant, benefit for almost all secondary outcomes in the three acupuncture groups compared with the control group. We found no relevant differences between the three acupuncture groups.

Interpretation:

Acupuncture tested appeared to have a clinically minor effect on migraine prophylaxis compared with sham acupuncture.

Trial Registration:

Clinicaltrials.gov {"type":"clinical-trial","attrs":{"text":"NCT00599586","term_id":"NCT00599586"}}NCT00599586About 6%–8% of men and 16%–18% of women in the United States and England experience migraines, with or without an aura.^1,2 A prevalence of 1% has been reported in mainland China,³ compared with 4.7% in Hong Kong and 9.1% in Taiwan.^4,5 A recent Cochrane meta-analysis suggests that acupuncture as migraine prophylaxis is safe and effective and should be considered as a treatment option for willing patients.⁶Although the specific effects acupuncture are controversial, acupuncture, as it is currently practised, clearly differentiates between real acupuncture points and nonacupuncture points. The Chinese Government launched the National Basic Research Program to obtain more data about the specificity of acupuncture points.⁷Trials from Italy and Brazil^8,9 showed that acupuncture was more effective than sham acupuncture in preventing migraines, but other trials have reported no differences.^10–13 There is no evidence that one acupuncture strategy is more effective than another for treating migraines. According to acupuncture theory, a headache on the lateral side is usually defined as a Shaoyang headache. In Jinkuiyi,¹⁴ migraines are said to affect the yang meridians (including the Taiyang, Yangming and Shaoyang meridians). In Lingshu,¹⁵ the Shaoyang meridians are said to go through the lateral side of the body, therefore the Shaoyang meridians are thought to be superior for treating migraines. Some points on the Shaoyang meridians are regarded as being more specific for migraines than other points.¹⁶Our aim was to investigate whether acupuncture at specific acupuncture points was more efficacious in preventing migraine than sham acupuncture at nonacupuncture points. We also investigated whether the efficacy varied when acupuncture points along different meridians or points along the same meridian were used.     

Effect of etanercept in polymyalgia rheumatica: a randomized controlled trial

Effectiveness of automated locomotor training in patients with acute incomplete spinal cord injury: A randomized controlled multicenter trial

Background  

A large proportion of patients with spinal cord injury (SCI) regain ambulatory function. However, during the first 3 months most of the patients are not able to walk unsupported. To enable ambulatory training at such an early stage the body weight is partially relieved and the leg movements are assisted by two therapists. A more recent approach is the application of robotic based assistance which allows for longer training duration. From motor learning science and studies including patients with stroke, it is known that training effects depend on the duration of the training. Longer trainings result in a better walking function. The aim of the present study is to evaluate if prolonged robot assisted walking training leads to a better walking outcome in patients with incomplete SCI and whether such training is feasible or has undesirable effects.     

Effectiveness of peer-led self-management coaching for patients recently diagnosed with Type 2 diabetes mellitus in primary care: a randomized controlled trial

Diabet. Med. 29, e390-e397 (2012) SUMMARY: Aims To study the effectiveness of a peer-led self-management coaching intervention in recently diagnosed patients with Type 2 diabetes. Methods Randomized controlled trial of recently diagnosed patients with Type 2 diabetes from 54 participating general practices. The intervention group received three home visits by an experienced peer (expert patient) who adhered to the recommended treatment and lifestyle guidelines. Together with their expert patient, participants set feasible goals and these were evaluated in the next visit. Participants in the control group received care as usual. At baseline, 3?months and 6?months post-intervention, participants completed a questionnaire measuring changes in self-efficacy, coping, physical activity, dietary habits, psychological well-being, depressive symptoms and diabetes related distress. Results In total, 327 patients were eligible for inclusion in the study of which 133 consented to participate.
