RESUMEN

OBJECTIVE: To evaluate the acceptability of a community health worker (CHW) intervention designed to improve the oral health of low-income, urban Chinese immigrant adults. BACKGROUND: Given that both dental caries and periodontitis are behaviourally mediated, biofilm-based diseases that are largely preventable with attention to regular oral hygiene practices and preventive dental visits, strategies to arrest or even heal carious lesions and high-quality maintenance care and plaque control without the need to resort to aerosol-generating surgical approaches are evidence-based best practices. Older immigrants have poorer oral health than older US-born natives, motivating the need for delivery of more effective and affordable services to this vulnerable population. MATERIALS AND METHODS: CHWs were trained by the NYU College of Dentistry dental hygienist faculty members using dental models and flip charts to instruct patients on proper brushing and flossing techniques. In addition, they discussed the presented oral health promotion information one-on-one with patients, addressed any expressed concerns and encouraged prevention of oral conditions through regular dental visits and brushing with fluoride toothpaste. RESULTS: More than 98% of the 74 older Chinese adult participants strongly agreed/agreed that the CHWs helped them to improve how they take care of their health, the CHWs answered their questions and concerns, the information and topics were informative, and the in-person demonstrations were helpful in improving oral health. CONCLUSION: The health of all communities depends on access to comprehensive care, including oral health care, in the wake of COVID-19. CHW interventions are acceptable to and may reach marginalised and immigrant communities.

RESUMEN

Importance: Despite limited effectiveness of pay-for-performance (P4P), payers continue to expand P4P nationally. Objective: To test whether increasing bonus size or adding the behavioral economic principles of increased social pressure (ISP) or loss aversion (LA) improves the effectiveness of P4P. Design, Setting, and Participants: Parallel studies conducted from January 1 to December 31, 2016, consisted of a randomized clinical trial with patients cluster-randomized by practice site to an active control group (larger bonus size [LBS] only) or to groups with 1 of 2 behavioral economic interventions added and a cohort study comparing changes in outcomes among patients of physicians receiving an LBS with outcomes in propensity-matched physicians not receiving an LBS. A total of 8118 patients attributed to 66 physicians with 1 of 5 chronic conditions were treated at Advocate HealthCare, an integrated health system in Illinois. Data were analyzed using intention to treat and multiple imputation from February 1, 2017, through May 31, 2018. Interventions: Physician participants received an LBS increased by a mean of $3355 per physician (LBS-only group); prefunded incentives to elicit LA and an LBS; or increasing proportion of a P4P bonus determined by group performance from 30% to 50% (ISP) and an LBS. Main Outcomes and Measures: The proportion of 20 evidence-based quality measures achieved at the patient level. Results: A total of 86 physicians were eligible for the randomized trial. Of these, 32 were excluded because they did not have unique attributed patients. Fifty-four physicians were randomly assigned to 1 of 3 groups, and 33 physicians (54.5% male; mean [SD] age, 57 [10] years) and 3747 patients (63.6% female; mean [SD] age, 64 [18] years) were included in the final analysis. Nine physicians and 864 patients were randomized to the LBS-only group, 13 physicians and 1496 patients to the LBS plus ISP group, and 11 physicians and 1387 patients to the LBS plus LA group. Physician characteristics did not differ significantly by arm, such as mean (SD) physician age ranging from 56 (9) to 59 (9) years, and sex (6 [46.2%] to 6 [66.7%] male). No differences were found between the LBS-only and the intervention groups (adjusted odds ratio [aOR] for LBS plus LA vs LBS-only, 0.86 [95% CI, 0.65-1.15; P = .31]; aOR for LBS plus ISP vs LBS-only, 0.95 [95% CI, 0.64-1.42; P = .81]; and aOR for LBS plus ISP vs LBS plus LA, 1.10 [95% CI, 0.75-1.61; P = .62]). Increased bonus size was associated with a greater increase in evidence-based care relative to the comparison group (risk-standardized absolute difference-in-differences, 3.2 percentage points; 95% CI, 1.9-4.5 percentage points; P < .001). Conclusions and Relevance: Increased bonus size was associated with significantly improved quality of care relative to a comparison group. Adding ISP and opportunities for LA did not improve quality. Trial Registration: ClinicalTrials.gov Identifier: NCT02634879.

RESUMEN

BACKGROUND: Psoriasis is a chronic inflammatory disease associated with dyslipidemia, cardiovascular events, and mortality. We aimed to assess and compare the effect of treatment of moderate-to-severe psoriasis with adalimumab or phototherapy on vascular inflammation and cardiovascular biomarkers. METHODS AND RESULTS: Randomized, double-blind, trial of adalimumab, phototherapy, and placebo (1:1:1) for 12 weeks, with crossover to adalimumab for 52 weeks total. Outcomes included vascular inflammation by 18F-fluorodeoxyglucose positron emission tomography/computed tomography and biomarkers of inflammation, insulin resistance, and lipoproteins. Ninety-seven patients were randomized, 92 completed the randomized controlled trial portion; 81 entered the adalimumab extension with 61 completing 52 weeks of adalimumab. There was no difference in change in vascular inflammation at week 12 in the adalimumab group (change compared with placebo, 0.64%; 95% confidence interval, -5.84% to 7.12%) or the phototherapy group (-1.60%; 95% confidence interval, -6.78% to 3.59%) or after 52-week adalimumab treatment (0.02% compared with initiation; 95% confidence interval, -2.85% to 2.90%). Both adalimumab and phototherapy decreased inflammation by serum CRP, interleukin-6. Only adalimumab reduced tumor necrosis factor and glycoprotein acetylation at 12 and 52 weeks. Neither had an impact on metabolic markers (insulin, adiponectin, and leptin). Only phototherapy increased high-density lipoprotein-p at 12 weeks. At 52-week of adalimumab cholesterol efflux and high-density lipoprotein-p were reduced. CONCLUSIONS: Adalimumab reduced key markers of inflammation including glycoprotein acetylation compared with phototherapy with no effect on glucose metabolism and vascular inflammation, and potential adverse effects on high-density lipoprotein. Glycoprotein acetylation improvement may partially explain the beneficial effects of adalimumab seen in observational studies. Larger studies with more detailed phenotyping of vascular disease should assess the comparative differences in the effects of adalimumab and phototherapy seen in our study.

RESUMEN

BACKGROUND: Observational studies suggest that higher volumes of physical activity are associated with a lower risk of disease recurrence among survivors of colon cancer. However, the feasibility and safety of prescribing higher volumes of physical activity to survivors of colon cancer are unknown. Furthermore, the pathways through which exercise may reduce disease recurrence are unknown. PATIENTS AND METHODS: Survivors of stage I to III colon cancer were randomized to usual-care control, 150 minutes per week of aerobic exercise (low-dose), or 300 minutes per week of aerobic exercise (high-dose). Changes in soluble intercellular adhesion molecule-1 and vascular adhesion molecule-1 prognostic biomarkers were examined. RESULTS: From January 2015 to February 2016, 39 patients were enrolled (n = 13 usual-care control; n = 14 low-dose; n = 12 high-dose), and 38 participants completed the study (97% follow-up). Over 6 months, the low-dose group completed 142 minutes per week (92.8% adherence), and the high-dose group completed 247 minutes per week (89.0% adherence) of exercise. Compared with the control group, changes in soluble intercellular adhesion molecule-1 were -134.9 ng/mL (95% confidence interval, -238.1 to -31.6 ng/mL) in the low-dose group and -114.8 ng/mL (95% confidence interval, -222.5 to -7.1 ng/mL) in the high-dose group (linear Ptrend = .023; nonlinear Ptrend = .044). No changes were observed for soluable vascular adhesion molecule-1 (linear Ptrend = .791; nonlinear Ptrend = .604). Non-serious adverse events occurred at similar rates among randomized groups. No serious adverse events occurred. CONCLUSION: Higher volumes of moderate-intensity aerobic exercise, up to 300 minutes per week, are feasible, safe, and elicit favorable changes in prognostic biomarkers among patients recently treated for stage I to III colon cancer. These data can be used to guide clinical recommendations for patients, and inform future trials.

RESUMEN

Sorafenib has an antitumor activity in patients with radioactive iodine-refractory differentiated thyroid carcinoma (RAIR-DTC). Prior research has implicated signaling through the MAPK and AKT/PI3K pathways in the progression of DTC. To assess whether the activity of these pathways is predictive of response to sorafenib, we retrospectively studied molecular tumor markers from these two pathways from a phase 2 study of sorafenib in RAIR-DTC. Tumor samples from 40 of 53 DTC subjects obtained prior to initiation of sorafenib were immunostained with DAB-labeled antibodies to phospho-AKT (pAKT), phospho-ERK (pERK), and phospho-S6 (pS6). BRAFV600E genetic mutation analysis was performed on all samples. Expression levels and mutational status were compared to response and progression-free survival (PFS) for each patient. Low tumor expression of nuclear pAKT was associated with partial response to sorafenib (p < 0.01). Patients with nuclear pAKT expression that was below the median for our sample were more than three times as likely to have a partial response as patients with equal to or above median expression. There was no correlation between tumor expression of nuclear pERK or pS6 and response. Endothelial cell and pericyte expression of pERK, pAKT, and pS6 were not predictive of response. There was no correlation between BRAFV600E mutation status and partial response. No correlation was observed between either the expression of pAKT, pERK, or pS6, or the presence of the BRAFV600E mutation, and PFS. In conclusion, lower tumor expression of nuclear pAKT was associated with higher rate of response to sorafenib. This observation justifies evaluation of combination therapy with sorafenib and an inhibitor of the PI3K/AKT signaling pathway in RAIR-DTC.

RESUMEN

BACKGROUND: There is little evidence to guide the establishment of treatment goals for moderate to severe psoriasis in the clinical setting. OBJECTIVE: We sought to compare Dermatology Life Quality Index scores and prescription topical medication use between patients with clear versus almost clear skin. METHODS: This was a multicenter cross-sectional study of 97 patients with clear skin and 441 patients with almost clear skin receiving current systemic therapy or phototherapy for a primary indication of plaque psoriasis evaluated at 1 of 10 US outpatient dermatology sites participating in the Dermatology Clinical Effectiveness Research Network. RESULTS: In adjusted analyses, patients with clear versus almost clear skin were more likely to report no impact of psoriasis on quality of life (relative risk 1.60; 95% confidence interval 1.37-1.86). Patients with clear versus almost clear skin were also more likely to report no prescription topical medication use in the preceding week (relative risk 2.08; 95% confidence interval 1.73-2.49). LIMITATIONS: Cross-sectional design prohibits longitudinal assessment of outcomes. CONCLUSIONS: Clinically important differences in quality of life and prescription topical medication use exist between patients with clear versus almost clear skin. Collectively, our results indicate that achievement of clear skin may be an important clinical distinction among patients with moderate to severe psoriasis.

RESUMEN

BACKGROUND: Despite widespread dissatisfaction and low treatment persistence in moderate to severe psoriasis, patients' reasons behind treatment discontinuation remain poorly understood. OBJECTIVES: We sought to characterize patient-reported reasons for discontinuing commonly used treatments for moderate to severe psoriasis in real-world clinical practice. METHODS: A total of 1095 patients with moderate to severe plaque psoriasis from 10 dermatology practices who received systemic treatments completed a structured interview. Eleven reasons for treatment discontinuation were assessed for all past treatments. RESULTS: A total of 2231 past treatments were reported. Median treatment duration varied by treatment, ranging from 6.0 to 20.5 months (P < .001). The frequency of each cited discontinuation reasons differed by treatment (all P < .01). Patients who received etanercept (odds ratio [OR] 5.19; 95% confidence interval [CI] 3.23-8.33) and adalimumab (OR 2.10; 95% CI 1.20-3.67) were more likely to cite a loss of efficacy than those who received methotrexate. Patients who received etanercept (OR 0.34; 95% CI 0.23-0.49), adalimumab (OR 0.48; 95% CI 0.30-0.75), and ultraviolet B phototherapy (OR 0.21; 95% CI 0.14-0.31) were less likely to cite side effects than those who received methotrexate, whereas those who received acitretin (OR 1.56; 95% CI 1.08-2.25) were more likely to do so. Patients who underwent ultraviolet B phototherapy were more likely to cite an inability to afford treatment (OR 7.03; 95% CI 3.14-15.72). LIMITATIONS: The study is limited by its reliance on patient recall. CONCLUSIONS: Different patterns of treatment discontinuation reasons are important to consider when developing public policy and evidence-based treatment approaches to improve successful long-term psoriasis control.

RESUMEN

OBJECTIVE: To compare the effectiveness of biologic systemic therapy, nonbiologic systemic therapy, and phototherapy for treatment of psoriasis. DESIGN: A cross-sectional design was used. SETTING: Ten outpatient dermatology sites across the United States participating in the Dermatology Clinical Effectiveness Research Network contributed to the study. PARTICIPANTS: A total of 713 patients with plaque psoriasis receiving systemic monotherapy (ie, methotrexate sodium, adalimumab, etanercept, or ustekinumab) or narrowband UV-B phototherapy. MAIN OUTCOME MEASURES: The primary outcome of the study was clear or almost clear skin on the Physician Global Assessment scale. Secondary outcomes were score on the Psoriasis Area and Severity Index, affected body surface area, and score on the Dermatology Life Quality Index. RESULTS: The proportion of patients with clear or almost clear ratings on the Physician Global Assessment scale differed among treatments: methotrexate (23.8%), adalimumab (47.7%), etanercept (34.2%), ustekinumab (36.1%), and narrowband UV-B (27.6%) (P < .001). In adjusted analyses, patients receiving adalimumab (relative response rate, 2.15; 95% CI, 1.60-2.90), etanercept (1.45; 1.06-1.97), and ustekinumab (1.57; 1.06-2.32) were more likely to have clear or almost clear skin vs patients receiving methotrexate. Patients receiving phototherapy showed no significant difference (1.35; 95% CI, 0.93-1.96) compared with those receiving methotrexate. No response difference was observed with respect to quality of life. Treatment doses were double the recommended doses in 36.1% of patients taking etanercept and 11.8% of those taking adalimumab;10.6% of patients undergoing phototherapy received the recommended treatment frequency. CONCLUSIONS: The effectiveness of psoriasis therapies in clinical practice may be lower than that reported in previous trials. Although relative differences in objective response rates among therapies may exist, absolute differences are small and may not be clinically significant. Dosing of common therapies varied from trial recommendations. These results provide novel benchmarks emphasizing the critical importance of studying effectiveness in real-world practice.

RESUMEN

BACKGROUND: Despite increasing therapies for moderate to severe psoriasis, dermatologists' treatment preferences are unknown. OBJECTIVE: We sought to assess dermatologists' preferences for first-line treatments and their selection determinants. METHODS: We surveyed 1000 US dermatologists (500 National Psoriasis Foundation and 500 American Academy of Dermatology members who treat psoriasis) about their preferences for first-line treatment of moderate to severe psoriasis in healthy adults of childbearing age using standardized patient vignettes. RESULTS: The response rate was 39% (N = 387). Preferred therapies for male and female patients were: ultraviolet (UV) B (40% and 56%, respectively), etanercept (15% and 19%), methotrexate (16% and 4%), and adalimumab (12% and 10%). Of respondents, 66% administered phototherapy in their practice. After adjusting for all physician characteristics, those preferring first-line UVB for male or female patients were significantly more likely to have phototherapy in their practice (odds ratio [OR] 3.4, 95% confidence interval [CI] 1.8-6.6 and OR 2.8, 95% CI 1.5-5.3, respectively) and to have used UVB in more than 10 patients in the last 3 months (OR 8.0, 95% CI 3.9-16.4; OR 9.6, 95% CI 4.3-21.6). Dermatologists in the Midwest were more likely than those in the Northeast to prefer adalimumab first line for male and female patients. LIMITATIONS: We surveyed only dermatologists with interest in treating psoriasis and elicited their treatment preferences for a single base case scenario. Treatment preferences may differ between survey respondents and nonrespondents. CONCLUSION: UVB is most commonly preferred as a first-line treatment for moderate to severe psoriasis in healthy adults, and preferences vary based on region, phototherapy availability, and prior treatment use.

RESUMEN

PURPOSE: Given the molecular pathophysiology of thyroid cancer and the spectrum of kinases inhibited by sorafenib, including Raf kinase, vascular endothelial growth factor receptors, platelet-derived growth factor receptor, and RET tyrosine kinases, we conducted an open-label phase II trial to determine the efficacy of sorafenib in patients with advanced thyroid carcinoma. PATIENTS AND METHODS: Eligible patients with metastatic, iodine-refractory thyroid carcinoma received sorafenib 400 mg orally twice daily. Responses were measured radiographically every 2 to 3 months. The study end points included response rate, progression-free survival (PFS), and best response by Response Evaluation Criteria in Solid Tumors. RESULTS: Thirty patients were entered onto the study and treated for a minimum of 16 weeks. Seven patients (23%; 95% CI, 0.10 to 0.42) had a partial response lasting 18+ to 84 weeks. Sixteen patients (53%; 95% CI, 0.34 to 0.72) had stable disease lasting 14 to 89+ weeks. Seventeen (95%) of 19 patients for whom serial thyroglobulin levels were available showed a marked and rapid response in thyroglobulin levels with a mean decrease of 70%. The median PFS was 79 weeks. Toxicity was consistent with other sorafenib trials, although a single patient died of liver failure that was likely treatment related. CONCLUSION: Sorafenib has clinically relevant antitumor activity in patients with metastatic, iodine-refractory thyroid carcinoma, with an overall clinical benefit rate (partial response + stable disease) of 77%, median PFS of 79 weeks, and an overall acceptable safety profile. These results represent a significant advance over chemotherapy in both response rate and PFS and support further investigation of this agent in these patients.

RESUMEN

BACKGROUND: There is a need for safe, inexpensive, and effective psoriasis therapies. Many anecdotal accounts of patients' successful treatment with the alternative medicine curcumin exist. OBJECTIVE: We sought to determine the safety and efficacy of oral curcumin in patients with psoriasis. METHODS: We conducted a phase II, open-label, Simon's two-stage trial of 4.5 g/d of oral curcuminoid C3 complex in patients with plaque psoriasis. End points included improvement in Physicians Global Assessment score, Psoriasis Area and Severity Index score, and safety end points throughout the study. RESULTS: The intention-to-treat analysis response rate was 16.7% (95% confidence interval: 2%, 48%) and both responders achieved a Psoriasis Area and Severity Index 75 score. There were no study-related adverse events that necessitated participant withdrawal. LIMITATIONS: Small sample size and lack of placebo group are limitations. CONCLUSION: The response rate was low and possibly caused by a placebo effect or the natural history of psoriasis. Large placebo-controlled studies are necessary before recommending oral curcumin as a psoriasis treatment.

RESUMEN

Hormone-related supplements (HRS), many of which contain phytoestrogens, are widely used to manage menopausal symptoms, yet their relationship with breast cancer risk has generally not been evaluated. We evaluated whether use of HRS was associated with breast cancer risk, using a population-based case-control study in 3 counties of the Philadelphia metropolitan area consisting of 949 breast cancer cases and 1,524 controls. Use of HRS varied significantly by race, with African American women being more likely than European American women to use any herbal preparation (19.2% vs. 14.7%, p=0.003) as well as specific preparations including black cohosh (5.4% vs. 2.0%, p=0.003), ginseng (12.5% vs. 7.9%, p<0.001) and red clover (4.7% vs. 0.6%, p<0.001). Use of black cohosh had a significant breast cancer protective effect (adjusted odds ratio 0.39, 95% CI: 0.22-0.70). This association was similar among women who reported use of either black cohosh or Remifemin (an herbal preparation derived from black cohosh; adjusted odds ratio 0.47, 95% CI: 0.27-0.82). The literature reports that black cohosh may be effective in treating menopausal symptoms, and has antiestrogenic, antiproliferative and antioxidant properties. Additional confirmatory studies are required to determine whether black cohosh could be used to prevent breast cancer.
