<b>Objective</b>: Evaluate the associations between long-term change and variability in glycemia with risk of HF among patients with T2DM. <p><b>Research Design and Methods: </b>Among participants with T2DM enrolled in the ACCORD trial, variability in HbA1c was assessed from stabilization of HbA1c following enrollment (8 months) to 3 years of follow-up as follows: average successive variability (ASV=average absolute difference between successive values), coefficient of variation (CV=standard deviation/mean), and standard deviation. Participants with HF at baseline or within 3 years of enrollment were excluded. Adjusted Cox models were used to evaluate the association of % change (from baseline to 3 years of follow-up) and variability in HbA1c over the first 3 years of enrollment and subsequent risk of HF.</p> <p><b>Results</b>: The study included 8,576 patients. Over a median follow-up of 6.4 years from the end of variability measurements at year 3, 388 patients had an incident HF hospitalization. Substantial changes in HbA1c were significantly associated with higher risk of HF [HR (95% CI) for ≥10% decrease = 1.32 (1.08-1.75), ≥10% increase = 1.55 (1.19-2.04), ref: <10% change in HbA1c]. Higher long-term variability in HbA1c was significantly associated with higher risk of HF [HR (95% CI) per 1 SD of ASV = 1.34 (1.17-1.54)] independent of baseline risk factors and interval changes in cardiometabolic parameters.

Abstract Objectives Long-term glycemic variability has been related to increased risk of vascular complication in patients with diabetes. However, the association between parameters of long-term glycemic variability and risk of stroke remains not fully determined. We performed a meta-analysis to systematically evaluate the above association. Methods Medline, Embase, and Web of Science databases were searched for longitudinal follow-up studies comparing the incidence of stroke in diabetic patients with higher or lower long-term glycemic variability. A random-effect model incorporating the potential heterogeneity among the included studies were used to pool the results. Results Seven follow-up studies with 725,784 diabetic patients were included, and 98% of them were with type 2 diabetes mellitus (T2DM). The mean follow-up duration was 7.7 years. Pooled results showed that compared to those with lowest category of glycemic variability, diabetic patients with the highest patients had significantly increased risk of stroke, as evidenced by glycemic variability analyzed by fasting plasma glucose coefficient of variation (FPG-CV: risk ratio [RR] = 1.24, 95% confidence interval [CI] 1.11 to 1.39, P < 0.001; I2 = 53%), standard deviation of FPG (FPG-SD: RR = 1.16, 95% CI 1.02 to 1.31, P = 0.02; I2 = 74%), HbA1c coefficient of variation (HbA1c-CV: RR = 1.88, 95% CI 1.61 to 2.19 P < 0.001; I2 = 0%), and standard deviation of HbA1c (HbA1c-SD: RR = 1.73, 95% CI 1.49 to 2.00, P < 0.001; I2 = 0%). Conclusions Long-term glycemic variability is associated with higher risk of stroke in T2DM patients.

Background: Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is a rare variant of HL that accounts for 5% of all HL cases. The expression of CD20 on neoplastic lymphocytes provides a suitable target for novel treatments based on Rituximab. Due to its rarity, consolidated and widely accepted treatment guidelines are still lacking for this disease. Methods: Between 1 December 2007 and 28 February 2018, sixteen consecutive newly diagnosed adult patients with NLPHL received Rituximab (induction ± maintenance)-based therapy, according to the baseline risk of German Hodgkin Study Group prognostic score system. The treatment efficacy and safety of the Rituximab-group were compared to those of a historical cohort of 12 patients with NLPHL who received Doxorubicin, Bleomycin, Vinblastine, Dacarbazine (ABVD) chemotherapy followed by radiotherapy (RT), if needed, according to a similar baseline risk. The primary outcome was progression-free survival (PFS) and secondary outcomes were overall survival (OS) and side-effects (according to the Common Terminology Criteria for Adverse Events, v4.03). Results: After a 7-year follow-up (range, 1–11 years), PFS was 100% for patients treated with the Rituximab-containing regimen versus 66% for patients of the historical cohort (p = 0.036). Four patients in the latter group showed insufficient response to therapy. The PFS for early favorable and early unfavorable NLPHLs was similar between treatment groups, while a better PFS was recorded for advanced-stages treated with the Rituximab-containing regimen. The OS was similar for the two treatment groups. Short- and long-term side-effects were more frequently observed in the historical cohort. Grade ≥3 neutropenia was more frequent in the historical cohort compared with the Rituximab-group (58.3% vs. 18.7%, respectively; p = 0.03). Long-term non-hematological toxicities were observed more frequently in the historical cohort. Conclusion: Our results confirm the value of Rituximab in NLPHL therapy and show that Rituximab (single-agent) induction and maintenance in a limited-stage, or Rituximab with ABVD only in the presence of risk factors, give excellent results while sparing cytotoxic agent- and/or RT-related damage. Furthermore, Rituximab inclusion in advanced-stage therapeutic strategy seems to improve PFS compared to conventional chemo-radiotherapy.

Thirty-seven patients with advanced gastroenteropancreatic neuroendocrine tumors (GEPNETs) were treated on a prospective phase II single-center study with 4 cycles of 7.8 GBq 177Lu-octreotate combined with capecitabine and temozolomide chemotherapy (CAPTEM). Each 8-week cycle combined radiopeptide therapy with 14 days of capecitabine (1500 mg/m2) and 5 days of temozolomide (200 mg/m2). The incidence of grade ≥3 hematologic toxicity was analysed. We found that at a median follow-up of 7-years (range 1-10), 6 (16%) patients developed persistent hematologic toxicity (PHT, defined as sustained grade ≥3 hematologic toxicity beyond 36-months follow up) and 3 (8%) developed MDS/AL with a median time-to-event of 46 and 34-months respectively. Estimated cumulative incidence of MDS/AL was 11% (95% CI: 3.45 to 24.01). Development of PHT was the only significant risk factor for secondary (RR, 16; 95% CI: 2.53 to 99.55; p<0.001). The median PFS was 48 months (95% CI: 40.80-55.20) and median OS was 86 months (95% CI: 56.90-115.13). 21 deaths were recorded, including 13 (62%) due to progressive disease and all 3 (14%) patients with MDS/AL. We conclude that 177Lu-octreotate CAPTEM therapy for GEPNETs is associated with a risk of long-term hematologic toxicity. The rising cumulative incidence of MDS/AL >10% mandates for the long-term monitoring of treated patients. However, time to onset is unpredictable and incidence does not correlate with conventional baseline risk factors. Novel methods are required for stratification of prospective patients based on genetic risk.

Background: The Multi-Ethnic Study of Atherosclerosis (MESA) is a large prospective epidemiologic study of the clinical factors that can predict transition from asymptomatic to symptomatic cardiovascular disease. Although prior studies have looked at ischemic stroke, they have not systematically examined the relationship between baseline ultrasound and inflammation measurements and subsequent primary stroke risk. Methods: The primary outcome is incident ischemic stroke during follow-up. The predictors are 9 ultrasound-derived measurements and 5 serum measurements related to inflammation. We fit Cox models to ischemic stroke and adjusted for patient age, hypertension, diabetes, total cholesterol, and smoking. Using DeLong’s method, we compared the AUC of the baseline adjusted model to the AUC of the model with predictor variables that were significant in the Cox models, to determine if they improved stroke prediction. Results: We included 6,095 patients with an average age of 61.9 years. The primary outcome of ischemic stroke was seen in 107 patients (1.8%) and the mean follow-up time was 7.7 years. In the Cox models, we found that small artery elasticity (SAE), carotid distensibility (CD), carotid stenosis (CS), and interleukin-6 (IL6) were associated with incident stroke. The AUC of the baseline model to predict stroke, which included patient age, hypertension, diabetes, total cholesterol, and smoking, was 0.745. When we added tertiles of SAE, CD, IL6 and categories of CS, the AUC improved to 0.765 (p=0.021 for difference). Conclusions: In a multiethnic cohort of patients without CVD at baseline, we found several ultrasound measurements and a serum marker of inflammation which predicted the occurrence of a primary ischemic stroke. Adding these basic ultrasound and serum measurements significantly improved the prediction of stroke, which could have implications for primary prevention efforts.

ABSTRACTBackground:Depression is a common problem in long-term care (LTC) settings. We sought to characterize depression symptom trajectories over six months among older residents, and to identify resident characteristics at baseline that predict symptom trajectory.Methods:This study was a secondary analysis of data from a six-month prospective, observational, and multi-site study. Severity of depressive symptoms was assessed with the 15-item Geriatric Depression Scale (GDS) at baseline and with up to six monthly follow-up assessments. Participants were 130 residents with a Mini-Mental State Examination score of 15 or more at baseline and of at least two of the six monthly follow-up assessments. Individual resident GDS trajectories were grouped using hierarchical clustering. The baseline predictors of a more severe trajectory were identified using the Proportional Odds Model.Results:Three clusters of depression symptom trajectory were found that described “lower,” “intermediate,” and “higher” levels of depressive symptoms over time (mean GDS scores for three clusters at baseline were 2.2, 4.9, and 9.0 respectively). The GDS scores in all groups were generally stable over time. Baseline predictors of a more severe trajectory were as follows: Initial GDS score of 7 or more, female sex, LTC residence for less than 12 months, and corrected visual impairment.Conclusions:The six-month course of depressive symptoms in LTC is generally stable. Most residents who experience a more severe symptom trajectory can be identified at baseline.

Background: Diabetic retinopathy is a common microvascular complication of diabetes. Previous research has shown that the macrovascular complications of diabetes, including stroke, are often comorbid with shared and, possibly, synergistic pathology. Methods: This is a secondary analysis of the subgroup of patients who enrolled in the ACCORD Eye study of ACCORD. The primary outcome is stroke during follow-up. The primary predictor was presence of diabetic retinopathy on the Early Treatment Diabetic Retinopathy Study Severity Scale as assessed from seven-field stereoscopic fundus photographs at study baseline. We fit adjusted Cox models to the primary outcome to provide hazard ratios for stroke and included interaction terms with the ACCORD randomization arms. Results: We included 2,828 patients with a mean (SD) age of 62.1 years and 61.8% were male. The primary outcome of stroke was met by 117 patients during a mean (SD) of 5.4 (1.8) years of follow-up. Diabetic retinopathy was present in 874/2,828 (30.9%) of patients at baseline, and was more common in patients with stroke versus without stroke (41.0 vs 30.5%, p=0.016). In the Cox model, adjusted for baseline patient age, gender, race, total cholesterol, Hgb A1c, smoking, and randomization arm, we found that diabetic retinopathy remained associated with incident stroke (HR 1.60, 95% CI 1.10-2.32, p=0.015) (Figure 1). This association was not affected by randomization to the ACCORD glucose intervention (p=0.305), lipid intervention (p=0.546), or blood pressure intervention (p=0.422). Conclusion: Diabetic retinopathy is associated with an increased risk of stroke, which suggests that the microvascular pathology inherent to diabetic retinopathy has larger cardiovascular implications.

Background: Guidelines recommend assessing orthostatic hypotension (OH) 3 minutes after rising from supine to standing positions. Hypothesis: Measurements performed immediately after standing will be as informative as measurements performed closer to 3 minutes after standing with regards to symptoms of dizziness or risk of adverse outcomes. Methods: OH, defined as a drop in blood pressure (systolic ≥20 mm Hg or diastolic ≥10 mm Hg) from the supine to standing position, was measured up to five times at 25 seconds intervals in middle-aged (range 44 to 66 years) ARIC participants (1987-1989). Associations between each measurement and history of dizziness upon standing were examined via logistic regression. We used Cox models to examine the association between each of five measurements with risk of fall, fracture, syncope, and all-cause mortality over a median follow-up of 23 years. Results: In 11,449 participants (mean age 54 years, 54% women, 26% black) 10% reported a history of dizziness upon standing. OH assessed at measurement 1 (performed at a mean of 28 seconds after standing) was associated with risk of fall ( P = 0.03), fracture ( P = 0.05), syncope ( P <0.001), and mortality ( P < 0.001) ( Table ). Furthermore, measurement 1 was the only measurement associated with higher odds of dizziness upon standing (OR: 1.5; P = 0.001). Measurement 2 (performed on average 53 seconds after standing) was associated with all long-term outcomes. Measurements 4 and 5 (mean 100 and 116 seconds after standing) were generally less informative with regards to prospective outcomes than earlier measurements and were not statistically associated with history of dizziness. Conclusions: OH measurements obtained, on average, within the first 30 seconds of standing were predictive of long-term adverse health outcomes and were the most strongly related to symptoms of dizziness compared to later measurements. These findings suggest that BP measurements for determining orthostatic hypotension should be performed immediately after standing.
