The purpose of this study was to investigate the efficacy of acupuncture as an adjunctive therapy to standard care for the relief of pain and dysfunction in elderly patients with osteoarthritis (OA) of the knee.Seventy-three patients with symptomatic OA of the knee were randomly assigned to treatment (acupuncture) or standard care (control). Analysis was performed on last score carried forward to account for patients who dropped out before completion. Patients self-scored Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Lequesne indices at baseline and at 4, 8 and 12 weeks. Patients in the control group were offered acupuncture treatment after 12 weeks. The data for these patients are pooled with those from the original acupuncture group for within-group analysis.Patients randomized to acupuncture improved on both WOMAC and Lequesne indices compared to those who received standard treatment alone. Significant differences on total WOMAC Scale were seen at 4 and 8 weeks. There appears to be a slight decline in effect at 4 weeks after cessation of treatment (12 weeks after first treatment). No adverse effects of acupuncture were reported.These data suggest that acupuncture is an effective and safe adjunctive therapy to conventional care for patients with OA of the knee.
The associations between self-reported rewards and difficulties of caregiving and burden were examined in a sample of 200 informal caregivers to older post-rehabilitation patients. Sixteen percent (16%) of caregivers reported that caregiving was physically difficult only, 15% reported emotional difficulties only, 11% reported social difficulties only, 17% reported multiple difficulties, and 40% had no difficulties. Each type of difficulty (e.g., social, emotional, and physical) was significantly associated with burden in univariate and multiple linear regression analyses, controlling for confounding characteristics. Caregivers reporting multiple types of difficulty experienced higher levels of burden than caregivers who reported only one type of difficulty. Caregivers who received more rewards from caregiving reported fewer difficulties. Caregiving rewards had no independent effect on burden but modified the associations between social and emotional difficulties and burden. In summary, caregiving rewards and difficulties were not mutually exclusive, and their relationship in turn affected burden.
An important problem with acupuncture research has been the difficulty in designing appropriate control groups. This pilot study attempted to resolve this problem. Ten patients with third molar extractions were assigned to an acupuncture group (n=7) or a placebo acupuncture group (n=3). Pain intensity and length of time to reach moderate pain after dental surgery were recorded by standard patient self-report. Results indicate that subjects treated with acupuncture reported longer pain-free duration times (mean 212min vs 65min) and experienced a 56.5% mean pain reduction compared to those who received placebo acupuncture. Even though the limited sample size reduced statistical power, this pilot study provides a model for placebo acupuncture control that will be utilised in future large-scale clinical acupuncture studies.
—To assess the safety and efficacy of optic nerve decompression surgery compared with careful follow-up alone in patients with nonarteritic anterior ischemic optic neuropathy (NAION).
Design.
—The Ischemic Optic Neuropathy Decompression Trial (IONDT) is a randomized, single-masked, multicenter trial.
Setting.
—Twenty-five US clinical centers.
Participants.
—The IONDT ceased recruitment on October 20, 1994, on the recommendation of its Data and Safety Monitoring Committee. The preliminary results presented herein are based on data as of September 8,1994, from 244 patients with NAION and visual acuity of 20/64 or worse. One hundred twenty-five patients had been randomized to careful follow-up, and 119 had been randomized to surgery, with 91 and 95, respectively, having completed 6 months of follow-up.
Intervention.
—Patients in the surgery group received optic nerve decompression surgery and follow-up ophthalmologic examinations; those in the careful follow-up group received ophthalmologic examinations at the same times as the surgery group.
Main Outcome Measures.
—Gain or loss of three or more lines of visual acuity on the New York Lighthouse chart at 6 months after randomization, as measured by a technician masked to treatment assignment.
Results.
—Patients assigned to surgery did no better when compared with patients assigned to careful follow-up regarding improved visual acuity of three or more lines at 6 months: 32.6% of the surgery group improved compared with 42.7% of the careful follow-up group. The odds ratio (OR) for three or more lines better, adjusted for baseline visual acuity and diabetes, was 0.74 (95% confidence interval [CI], 0.39 to 1.38). Patients receiving surgery had a significantly greater risk of losing three or more lines of vision at 6 months: 23.9% in the surgery group worsened compared with 12.4% in the careful follow-up group. The 6-month adjusted OR for three or more lines worse was 1.96 (95% CI, 0.87 to 4.41). No difference in treatment effect was observed between patients with progressive NAION and all others.
Conclusion.
—Results from the IONDT indicate that optic nerve decompression surgery for NAION is not effective, may be harmful, and should be abandoned. The spontaneous improvement rate is better than previously reported. (JAMA. 1995;273:625-632)
Media coverage of scientific research plays a major role in shaping public opinion and influencing medical practice. When an association is controversial, such as with hormone replacement therapy (HRT) and breast cancer, it is important that a balanced picture of the scientific literature be reported. The objective of this study was to assess whether scientific publications that do and do not support an HRT/breast cancer association were cited in the media in proportions similar to those with which they appear in the scientific literature. Scientific publications reporting on the HRT/breast cancer association published from January 1, 1995, to June 30, 2000, were identified through a systematic Medline search. Media reports from newspapers, magazines, television, and radio that reported on HRT and breast cancer were retrieved from an online database. Investigators independently recorded characteristics of the scientific publications and media reports. A total of 32 scientific publications were identified: 20 (62.5%) concluded there was an increased risk of breast cancer associated with HRT (positive publications), and 12 (37.5%) concluded there was no evidence for an association (null publications). Nearly half (47%) of the scientific publications were not cited by the media. There were 203 media citations of scientific publications: 82% were of positive publications and 18% were of null publications, representing a significant excess of citations of positive publications (p < 0.01). Media coverage of this controversial issue is based on a limited sample of the scientific publications. Moreover, the excess of media citations for positive scientific publications suggests a bias against null scientific publications.
Comorbidity is a known risk factor for antibiotic-resistant bacterial infections. Although aggregate comorbidity measures are useful in epidemiologic research, none of the existing measures was developed for use with this outcome. This study compared the utility of two comorbidity measures, the Charlson Comorbidity Index and the Chronic Disease Score, in assessing the comorbidity-attributable risk of nosocomial infections with methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant enterococci (VRE). Two case-control studies were conducted at the University of Maryland Medical System in Baltimore, Maryland. Cases were inpatients with a first positive clinical culture of MRSA or VRE at least 48 hours postadmission (July 1, 1998-July 1, 2001). Three inpatient controls were randomly selected per case. The MRSA study included 2,164 patients, and the VRE study included 1,948. The scores' discrimination and calibration were measured by using the c statistic and Hosmer-Lemeshow chi-square test. The Charlson Comorbidity Index (c = 0.653) and Chronic Disease Score (c = 0.608) were similar discriminators of MRSA and VRE (c = 0.670 and c = 0.647, respectively). Calibration of the scores was poor for both outcomes (p < 0.05). A revised comorbidity measure specific to resistant infections would likely provide a better assessment of the comorbidity-attributable risk of antibiotic-resistant infections.
Depression is common in patients with inflammatory bowel disease (IBD) and contributes to poor quality of life (QoL). The use of information technology for the remote management of patients with IBD is growing, but little is known about its impact on depressive symptoms (DS) and QoL. We aimed to evaluate the impact of telemedicine on DS and generic QoL in IBD patients.We analyzed data from the Telemedicine for Patients with IBD (TELE-IBD) study. During this 12-month clinical trial, patients were randomized to receive text message-based telemedicine weekly (TELE-IBD W), every other week (TELE-IBD EOW), or to standard care. Depressive symptoms and QoL were assessed over time with the Mental Health Inventory 5 (MHI-5) and the Short Form 12 (SF-12), respectively. We compared the change in MHI-5 and SF-12 (with separate physical (PCS) and mental component summary (MCS) scores) between the study arms.A total of 217 participants were included in this analysis. After 1 year, there was no significant difference in the change in MHI-5 (TELE-IBD W +3.0 vs TELE-IBD EOW +0.7 vs standard care +3.4; P = 0.70), MCS (TELE-IBD W +1.4 vs TELE-IBD EOW +1.0 vs standard care +2.5; P = 0.89), and PCS scores (TELE-IBD W +0.4 vs TELE-IBD EOW +0.6 vs standard care +3.7; P = 0.06) between the groups.Text message-based telemedicine does not improve DS or QoL when compared with standard care in IBD patients treated at tertiary referral centers. Further studies are needed to determine whether telemedicine improves DS or QoL in settings with few resources.
