Despite the evidence suggesting that all treatments intended to be therapeutic are equally efficacious, the conjecture that one form of treatment, namely cognitive-behavioral therapy (CBT), is superior to all other treatment persists. The purpose of the current study was to (a) reanalyze the clinical trials from an earlier meta-analysis that compared CBT to ‘other therapies’ for depression and anxiety (viz., Tolin, 2010) and (b) conduct a methodologically rigorous and comprehensive meta-analysis to determine the relative efficacy of CBT and bona fide non-CBT treatments for adult anxiety disorders. Although the reanalysis was consistent with the earlier meta-analysis' findings of small to medium effect sizes for disorder-specific symptom measures, the reanalysis revealed no evidence for the superiority of CBT for depression and anxiety for outcomes that were not disorder-specific. Following the reanalysis, a comprehensive anxiety meta-analysis that utilized a survey of 91 CBT experts from the Association of Behavioral and Cognitive Therapists (ABCT) to consensually identify CBT treatments was conducted. Thirteen clinical trials met the inclusion criteria. There were no differences between CBT treatments and bona fide non-CBT treatments across disorder-specific and non-disorder specific symptom measures. These analyses, in combination with previous meta-analytic findings, fail to provide corroborative evidence for the conjecture that CBT is superior to bona fide non-CBT treatments.  相似文献

BackgroundThere is a paucity of interventional research that systematically assesses the role of exercise intensity and cardiorespiratory fitness, and their relationship with executive function in older adults. To address this limitation, we have examined the effect of a systematically manipulated exercise intervention on executive function.MethodsNinety-nine cognitively normal participants (age = 69.10 ± 5.2 years; n = 54 female) were randomized into either a high-intensity cycle-based exercise, moderate-intensity cycle-based exercise, or no-intervention control group. All participants underwent neuropsychological testing and fitness assessment at baseline (preintervention), 6-month follow-up (postintervention), and 12-month postintervention. Executive function was measured comprehensively, including measures of each subdomain: Shifting, Updating/ Working Memory, Inhibition, Verbal Generativity, and Nonverbal Reasoning. Cardiorespiratory fitness was measured by analysis of peak aerobic capacity; VO2peak.ResultsFirst, the exercise intervention was found to increase cardiorespiratory fitness (VO2peak) in the intervention groups, in comparison to the control group (F =10.40, p≤0.01). However, the authors failed to find mean differences in executive function scores between the high-intensity, moderate intensity, or inactive control group. On the basis of change scores, cardiorespiratory fitness was found to associate positively with the executive function (EF) subdomains of Updating/Working Memory (β = 0.37, p = 0.01, r = 0.34) and Verbal Generativity (β = 0.30, p = 0.03, r = 0.28) for intervention, but not control participants.ConclusionAt the aggregate level, the authors failed to find evidence that 6-months of high-intensity aerobic exercise improves EF in older adults. However, it remains possible that individual differences in experimentally induced changes in cardiorespiratory fitness may be associated with changes in Updating/ Working Memory and Verbal Generativity.  相似文献

Residual viral replication persists in a significant proportion of human immunodeficiency virus (HIV)-infected patients receiving potent antiretroviral therapy. To determine the source of this virus, levels of HIV RNA and DNA from lymphoid tissues and levels of viral RNA in serum, cerebrospinal fluid (CSF), and genital secretions in 28 patients treated for < or =2.5 years with indinavir, zidovudine, and lamivudine were examined. Both HIV RNA and DNA remained detectable in all lymph nodes. In contrast, HIV RNA was not detected in 20 of 23 genital secretions or in any of 13 CSF samples after 2 years of treatment. HIV envelope sequence data from plasma and lymph nodes from 4 patients demonstrated sequence divergence, which suggests varying degrees of residual viral replication in 3 and absence in 1 patient. In patients receiving potent antiretroviral therapy, the greatest virus burden may continue to be in lymphoid tissues rather than in central nervous system or genitourinary compartments.  相似文献

One hundred and three outpatients with endoscopically diagnosed duodenal ulcer were randomly allocated to treatment with either cimetidine 200 mg tds and 400 mg nocte, or ranitidine 150 mg bd for four weeks. The endoscopists were not aware of the treatment and took no part in the clinical management. On completion of treatment ulcers had healed in 43 of 51 (84%) patients given cimetidine and in 40 of 52 (77%) patients given ranitidine. There were no serious unwanted effects in either treatment group. The results show no significant difference between healing rates after four weeks of standard cimetidine therapy or ranitidine 150 mg bd.  相似文献

Background

Little has been reported about protocol-driven outpatient palliative care consultation (OPCC) for advanced heart failure (HF).

Objectives

To describe evaluation practices and treatment recommendations made during protocol-driven OPCCs for advanced HF.

Methods

We performed content analysis of OPCCs completed as part of ENABLE CHF-PC, an early palliative care HF intervention, conducted at sites in the Northeast and Southeast. T-tests, Fisher's exact, and Chi-square tests were used to evaluate sociodemographic, outcome measures, and site content differences.

Results

Of 61 ENABLE CHF-PC participants, 39 (64%) had an OPCC (Northeast, n=27; Southeast, n=12). Social and medical history assessed most were close relationships (n=35, 90%), family support (n=33, 85%), advance directive status (n=33, 85%), functional status (n=30, 77%); and symptoms were mood (n= 35, 90%), breathlessness (n=28, 72%), and chest pain (n=24, 62%). Treatment recommendations focused on care coordination (n=13, 33%) and specialty referrals (n=12, 31%). Between-site OPCC differences included assessment of family support (Northeast vs. Southeast: 100% vs. 50%), code status (96% vs. 58%), goals of care discussions (89% vs. 41.7%), and prognosis understanding (85% vs. 33%).

Conclusion

OPCCs for HF focused on evaluating medical and social history, along with goals of care and code status discussions. Symptom evaluation commonly included mood disorders, pain, dyspnea, and fatigue. Notable regional differences were found in topics evaluated and OPCC completion rates.  相似文献

Identifying signaling pathways that regulate hematopoietic stem and progenitor cell (HSPC) formation in the embryo will guide efforts to produce and expand HSPCs ex vivo. Here we show that sterile tonic inflammatory signaling regulates embryonic HSPC formation. Expression profiling of progenitors with lymphoid potential and hematopoietic stem cells (HSCs) from aorta/gonad/mesonephros (AGM) regions of midgestation mouse embryos revealed a robust innate immune/inflammatory signature. Mouse embryos lacking interferon γ (IFN-γ) or IFN-α signaling and zebrafish morphants lacking IFN-γ and IFN-ϕ activity had significantly fewer AGM HSPCs. Conversely, knockdown of IFN regulatory factor 2 (IRF2), a negative regulator of IFN signaling, increased expression of IFN target genes and HSPC production in zebrafish. Chromatin immunoprecipitation (ChIP) combined with sequencing (ChIP-seq) and expression analyses demonstrated that IRF2-occupied genes identified in human fetal liver CD34+ HSPCs are actively transcribed in human and mouse HSPCs. Furthermore, we demonstrate that the primitive myeloid population contributes to the local inflammatory response to impact the scale of HSPC production in the AGM region. Thus, sterile inflammatory signaling is an evolutionarily conserved pathway regulating the production of HSPCs during embryonic development.  相似文献

Oculopharyngeal muscular dystrophy (OPMD) is a rare autosomal dominant, progressive degenerative muscle disorder featuring dysphagia with limited therapeutic options. The aim of this study was to evaluate the safety and efficacy of repeated endoscopic dilatation for OPMD over a 15-year period. All patients seen at our Regional Swallowing Clinic with OPMD confirmed by genetic analysis were included. Cricopharyngeal dilatation was performed as an outpatient procedure using a wire-guided 18-mm (54 Fr) Savary-Gilliard bougie with the patient under sedation. Patients were offered repeat endoscopic dilatation when symptoms recurred. Symptom severity prior to initial dilatation and at follow-up was evaluated using the Sydney Swallow Questionnaire (SSQ). Nine patients (7 female, 2 male) were included for analysis. Median total treatment period was 13?years (range?=?3-15), median number of dilatations per patient was 7.2 (range?=?1-16), and median interval between treatments was 15?months (range?=?4.5-45). All patients recorded sustained symptom improvement. Mean SSQ score (out of 1,700) was 1,108.11 (SD?±?272.85) prior to first dilatation and 297.78 (SD?±?189.14) at last follow-up, representing a 73% decrease (95% CI?=?52-94) in degree of dysphagia symptoms (paired t-test, P?=?0.0001). All mean scores for individual questions also showed significant improvement (P?相似文献
