A Novel Approach to Depression Care: Efficacy of an Adapted Interpersonal Therapy in a Large, Urban Primary Care Setting.

The Collaborative Care Model (CoCM), in which social workers, primary care physicians, and a consulting psychiatrist work as a team, is an established approach to the treatment of common mental health conditions in primary care settings. Following implementation of a CoCM depression care program at our hospital-based academic primary care practice, we observed a low rate of retention with the use of problem solving therapy/behavioral activation (PST/BA). Our aim in this study was to evaluate the effectiveness of interpersonal psychotherapy (IPT), an evidence-based, flexible strategy that focuses on the relationship between depression and interpersonal challenges, compared to PST/BA. In 2015, most patients enrolled in our CoCM received PST/BA. In 2016, most patients received IPT. Patients who were enrolled and discharged from our CoCM depression care program in the years 2015 and 2016 and received either PST/BA or IPT, were included. Our primary measure was the difference in change in PHQ-9 score between the PST/BA and the IPT groups. Secondary outcomes included the difference in the change in GAD-7 score and measures of glycemic and blood pressure control between the two groups. Two hundred thirty four patients were included in our analysis. One hundred sixty five received PST/BA and 69 received IPT. There was no difference between groups in baseline demographics or measures of depression, anxiety, presence of hypertension, or presence of prediabetes/diabetes. Our primary analysis demonstrated a greater decrease in PHQ-9 score in patients receiving IPT (9.93) compared to those receiving PST/BA (5.41) (p < 0.0001). The proportion of patients achieving a clinical response (PHQ-9 < 10) was also greater in the IPT group (71%) compared to the PST/BA group (44%). In a CoCM depression care program, IPT was a more effective strategy in improving depression symptoms as measured by PHQ-9 scores than PST/BA.

Management of bone health in postmenopausal women on aromatase inhibitors (AIs): a single health care system experience.

INTRODUCTION: Aromatase inhibitors (AIs) are the preferred therapy for postmenopausal women with early-stage estrogen receptor-positive breast cancers. However, their use causes bone loss and increased risks of osteoporosis and fractures. METHODS: This is a retrospective review of all postmenopausal women with breast cancer diagnosed and treated with AI between 2010 and 2015. Of the 564 women identified, 319 were eligible. RESULTS: The median age at AI initiation was 65 years (range 51-85 years), and the median duration of AI therapy was 28 months (1-72 months). The median number of DEXA scans per woman was 1 (0-4), performed at a median frequency of 24 months (1-48 months). Recommendations for calcium and vitamin D were in 66 and 59% of women, respectively. There were 52 (16%) women who received antiresorptive treatments with bisphosphonates (69%), denosumab (25%), or both drugs (6%). Based on guideline recommendations from six societies, starting antiresorptive treatment was unnecessary in 15-54% of women. CONCLUSIONS: In this single health system experience, women start antiresorptive drugs that are unnecessary in 15-52%. These results highlight the nonuniformity in guideline recommendations, and this has implications for quality of care, cost-effectiveness, and value-of-care analyses for preventing fractures.

High-dose atorvastatin reduces periodontal inflammation: a novel pleiotropic effect of statins.

OBJECTIVES: The purpose of this study was to test whether high-dose statin treatment would result in a reduction in periodontal inflammation as assessed by (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET)/computed tomography (CT). BACKGROUND: Periodontal disease (PD) is an independent risk factor for atherosclerosis. METHODS: Eighty-three adults with risk factors or with established atherosclerosis and who were not taking high-dose statins were randomized to atorvastatin 80 mg vs. 10 mg in a multicenter, double-blind trial to evaluate the impact of atorvastatin on arterial inflammation. Subjects were evaluated using FDG-PET/CT at baseline and at 4 and 12 weeks. Arterial and periodontal tracer activity was assessed while blinded to treatment allocation, clinical characteristics, and temporal sequence. Periodontal bone loss (an index of PD severity) was evaluated using contrast-enhanced CT images while blinded to clinical and imaging data. RESULTS: Seventy-one subjects completed the study, and 59 provided periodontal images for analysis. At baseline, areas of severe PD had higher target-to-background ratio (TBR) compared with areas without severe PD (mean TBR: 3.83 [95% confidence interval (CI): 3.36 to 4.30] vs. 3.18 [95% CI: 2.91 to 3.44], p = 0.004). After 12 weeks, there was a significant reduction in periodontal inflammation in patients randomized to atorvastatin 80 mg vs. 10 mg (ΔTBR 80 mg vs. 10 mg group: mean -0.43 [95% CI: -0.83 to -0.02], p = 0.04). Between-group differences were greater in patients with higher periodontal inflammation at baseline (mean -0.74 [95% CI: -1.29 to -0.19], p = 0.01) and in patients with severe bone loss at baseline (-0.61 [95% CI: -1.16 to -0.054], p = 0.03). Furthermore, the changes in periodontal inflammation correlated with changes in carotid inflammation (R = 0.61, p < 0.001). CONCLUSIONS: High-dose atorvastatin reduces periodontal inflammation, suggesting a newly recognized effect of statins. Given the concomitant changes observed in periodontal and arterial inflammation, these data raise the possibility that a portion of that beneficial impact of statins on atherosclerosis relate to reductions in extra-arterial inflammation, for example, periodontitis.

Positron emission tomography measurement of periodontal 18F-fluorodeoxyglucose uptake is associated with histologically determined carotid plaque inflammation.

OBJECTIVES: This study aimed to test the hypothesis that metabolic activity within periodontal tissue (a possible surrogate for periodontal inflammation) predicts inflammation in a remote atherosclerotic vessel, utilizing (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) imaging. BACKGROUND: Several lines of evidence establish periodontal disease as an important risk factor for atherosclerosis. FDG-PET imaging is an established method for measuring metabolic activity in human tissues and blood vessels. METHODS: One hundred twelve patients underwent FDG-PET imaging 92 ± 5 min after FDG administration (13 to 25 mCi). Periodontal FDG uptake was measured by obtaining standardized uptake values from the periodontal tissue of each patient, and the ratio of periodontal to background (blood) activity was determined (TBR). Standardized uptake value measurements were obtained in the carotid and aorta as well as in a venous structure. Localization of periodontal, carotid, and aortic activity was facilitated by PET coregistration with computed tomography or magnetic resonance imaging. A subset of 16 patients underwent carotid endarterectomy within 1 month of PET imaging, during which atherosclerotic plaques were removed and subsequently stained with anti-CD68 antibodies to quantify macrophage infiltration. Periodontal FDG uptake was compared with carotid plaque macrophage infiltration. RESULTS: Periodontal FDG uptake (TBR) is associated with carotid TBR (R = 0.64, p < 0.0001), as well as aortic TBR (R = 0.38; p = 0.029). Moreover, a strong relationship was observed between periodontal TBR and histologically assessed inflammation within excised carotid artery plaques (R = 0.81, p < 0.001). CONCLUSIONS: FDG-PET measurements of metabolic activity within periodontal tissue correlate with macrophage infiltration within carotid plaques. These findings provide direct evidence for an association between periodontal disease and atherosclerotic inflammation.
