RESUMO

BACKGROUND: There are currently no reference standards for the development of competence in bronchoscopy. RESEARCH QUESTION: The aims of this study were to (1) develop learning curves for bronchoscopy skill development and (2) estimate the number of bronchoscopies required to achieve competence. STUDY DESIGN AND METHODS: Trainees from seven North American academic centers were enrolled at the beginning of their pulmonology training. Performance during clinical bronchoscopies was assessed by supervising physicians using the Ontario Bronchoscopy Assessment Tool (OBAT). Group-level learning curves were modeled using a quantile regression growth model, where the dependent variable was the mean OBAT score and the independent variable was the number of bronchoscopies performed at the time the OBAT was completed. RESULTS: A total of 591 OBAT assessments were collected from 31 trainees. The estimated regression quantiles illustrate significantly different learning curves based on trainees' performance percentiles. When competence was defined as the mean OBAT score for all bronchoscopies rated as being completed without need for supervision, the mean OBAT score associated with competence was 4.54 (95% CI, 4.47-4.58). Using this metric, the number of bronchoscopies required to achieve this score varied from seven to 10 for the 90th percentile of trainees and from 109 to 126 for the lowest 10th percentile of trainees. When competence was defined as the mean OBAT score for the first independent bronchoscopy, the mean was 4.40 (95% CI, 4.20-4.60). On the basis of this metric, the number of bronchoscopies required varied from one to 11 for the 90th percentile of trainees and from 83 to 129 for the lowest 10th percentile of trainees. INTERPRETATION: We were able to generate learning curves for bronchoscopy across a range of trainees and centers. Furthermore, we established the average number of bronchoscopies required for the attainment of competence. This information can be used for purposes of curriculum planning and allows a trainee's progress to be compared with an established norm.

RESUMO

OBJECTIVE: This 5-year observational posthoc analysis of the REFLEX study and its open-label extension assessed clinical efficacy, radiographic response, and safety of rituximab (RTX) in patients with rheumatoid arthritis (RA) who had an inadequate response to tumor necrosis factor (TNF) inhibitors. METHODS: Patients in REFLEX were originally randomized to placebo (PBO) + methotrexate (MTX; PBO-randomized) or RTX + MTX (RTX-randomized). PBO-randomized patients were rescued with RTX as appropriate. Patients responding to initial RTX treatment could receive further RTX courses. For clinical efficacy and safety analyses, PBO-randomized patients were re-baselined prior to first RTX treatment and the data were pooled with RTX-randomized patient data. Efficacy outcomes 24 weeks after each course were calculated relative to first RTX pretreatment baseline. Radiographic outcomes were assessed relative to randomization baseline for both PBO-randomized and RTX-randomized groups. RESULTS: A total of 480 patients received ≥ 1 RTX course. At 24 weeks, American College of Rheumatology 20/50/70 responses were 62.0%, 30.8%, and 13.0%, respectively at course 1 (n = 400) and 70.3%, 41.8%, and 22.0% at course 5 (n = 91). European League Against Rheumatism good/moderate responses were 77.2% and 84.4% at courses 1 (n = 390) and 5 (n = 90). Rates of adverse events (AE), serious AE, and infections generally remained stable. Rate of progressive joint damage (PJD; change in mean Total Sharp Score) decreased over time in both PBO-randomized (n = 79) and RTX-randomized (n = 105) groups. Mean change from baseline in PJD over 5 years was greater in PBO-randomized versus RTX-randomized patients (5.51 vs 3.21). CONCLUSION: RTX re-treatment over 5 years is associated with maintained or improved efficacy, continued inhibition of PJD, and a safety profile consistent with that previously reported. A delay in initiating RTX treatment may result in increased PJD.

RESUMO

Psychological issues following hematopoietic cell transplantation (HCT) are unfortunately common. Literature specific to the transplant experience for the needs of adolescents and young adults (AYA) is lacking. The purpose of this article is to (1) describe the allogeneic transplant experience for AYA transplant patients during the first year following transplantation including demographic and treatment characteristics, (2) present AYA data obtained during and following a six-part posttransplant discharge study, (3) illustrate typical AYA experiences using case studies, and (4) propose AYA intervention strategies within Erickson's stages of psychosocial development. A quality of life model provided the research conceptual framework, and the content analysis framework for the qualitative research. Themes that emerged within each domain were the following: sexuality/fertility, fatigue, depression/poor coping/habits,adherence issues, use of technology, dependency issues, changes in roles/relationships, issues with school/education, financial issues, family problems/issues, miscellaneous, religion/spirituality, fear of future, uncertainty, life, death, more life appreciation. These data guide us for providing targeted interventions for the needs of this AYA population. This paper has presented literature and developmental theory, qualitative and qualitative data from an intervention study, and clinical cases in order to propose a developmental treatment model for AYA transplant patients. A coordinated and multidisciplinary approach is needed for the HCT patient who is an AYA.

RESUMO

PURPOSE: To assess the efficacy and adverse-events profile of combined treatment with ranibizumab and verteporfin photodynamic therapy (PDT) in patients with predominantly classic choroidal neovascularization (CNV) secondary to neovascular age-related macular degeneration. DESIGN: Two-year, multicenter, randomized, single-masked, controlled study. METHODS: Patients received monthly intravitreal injections of ranibizumab 0.5 mg (n = 106) or sham injections (n = 56). All patients received PDT on day zero, then quarterly as needed. Efficacy assessment included changes in visual acuity (VA) and lesion characteristics and PDT frequency. Adverse events were summarized by incidence and severity. RESULTS: At month 24, 88% of ranibizumab + PDT patients had lost <15 letters from baseline VA (vs 75% for PDT alone), 25% had gained >or=15 letters (vs 7% for PDT alone), and the two treatment arms differed by 12.4 letters in mean VA change (P < .05 for all between-group differences). The VA benefit of adding ranibizumab to PDT in year one persisted through year two. On average, ranibizumab + PDT patients exhibited less lesion growth and greater reduction of CNV leakage and subretinal fluid accumulation, and required fewer PDT retreatments, than PDT-alone patients (mean = 0.4 vs 3.0 PDT retreatments). Endophthalmitis and serious intraocular inflammation occurred, respectively, in 2.9% and 12.4% of ranibizumab + PDT patients and 0% of PDT-alone patients. Incidences of serious nonocular adverse events were similar in the two treatment groups. CONCLUSIONS: Through two years, ranibizumab + PDT was more effective than PDT alone and had a low rate of associated adverse events.

RESUMO

OBJECTIVE: To investigate the safety and efficacy of intravitreal ranibizumab treatment combined with verteporfin photodynamic therapy (PDT) in patients with predominantly classic choroidal neovascularization secondary to age-related macular degeneration. METHODS: In this 2-year, phase I/II, multicenter, randomized, single-masked, controlled study, patients received monthly ranibizumab (0.5 mg) (n = 106) or sham (n = 56) injections. The PDT was performed 7 days before initial ranibizumab or sham treatment and then quarterly as needed. MAIN OUTCOMES MEASURES: Proportion of patients losing fewer than 15 letters from baseline visual acuity at 12 months (primary efficacy outcome) and the incidence and severity of adverse events. RESULTS: At 12 months, 90.5% of the ranibizumab-treated patients and 67.9% of the control patients had lost fewer than 15 letters (P<.001). The most frequent ranibizumab-associated serious ocular adverse events were intraocular inflammation (11.4%) and endophthalmitis (1.9%; 4.8% if including presumed cases). On average, patients with serious inflammation had better visual acuity outcomes at 12 months than did controls. Key serious nonocular adverse events included myocardial infarctions in the PDT-alone group (3.6%) and cerebrovascular accidents in the ranibizumab-treated group (3.8%). CONCLUSION/APPLICATION TO CLINICAL PRACTICE: Ranibizumab + PDT was more efficacious than PDT alone for treating neovascular age-related macular degeneration. Although ranibizumab treatment increased the risk of serious intraocular inflammation, affected patients, on average, still experienced visual acuity benefit.

RESUMO

BACKGROUND: Ranibizumab--a recombinant, humanized, monoclonal antibody Fab that neutralizes all active forms of vascular endothelial growth factor A--has been evaluated for the treatment of neovascular age-related macular degeneration. METHODS: In this multicenter, 2-year, double-blind, sham-controlled study, we randomly assigned patients with age-related macular degeneration with either minimally classic or occult (with no classic lesions) choroidal neovascularization to receive 24 monthly intravitreal injections of ranibizumab (either 0.3 mg or 0.5 mg) or sham injections. The primary end point was the proportion of patients losing fewer than 15 letters from baseline visual acuity at 12 months. RESULTS: We enrolled 716 patients in the study. At 12 months, 94.5% of the group given 0.3 mg of ranibizumab and 94.6% of those given 0.5 mg lost fewer than 15 letters, as compared with 62.2% of patients receiving sham injections (P<0.001 for both comparisons). Visual acuity improved by 15 or more letters in 24.8% of the 0.3-mg group and 33.8% of the 0.5-mg group, as compared with 5.0% of the sham-injection group (P<0.001 for both doses). Mean increases in visual acuity were 6.5 letters in the 0.3-mg group and 7.2 letters in the 0.5-mg group, as compared with a decrease of 10.4 letters in the sham-injection group (P<0.001 for both comparisons). The benefit in visual acuity was maintained at 24 months. During 24 months, presumed endophthalmitis was identified in five patients (1.0%) and serious uveitis in six patients (1.3%) given ranibizumab. CONCLUSIONS: Intravitreal administration of ranibizumab for 2 years prevented vision loss and improved mean visual acuity, with low rates of serious adverse events, in patients with minimally classic or occult (with no classic lesions) choroidal neovascularization secondary to age-related macular degeneration.
