Introduction: Increasing evidence demonstrates a role of cardiovascular fat in the pathogenesis of CAD. It is unknown whether heart and vascular fat depots are related to atherosclerotic burden in women transitioning through menopause, a time of increasing CAD risk. Hypothesis: We hypothesize that volumes of epicardial (EAT), pericardial (PAT), total heart (TAT=EAT+PAT) and peri-aortic (PVAT) adipose tissues are associated with presence and severity of coronary artery calcification (CAC) in a sample of white and black midlife women. Methods: CAC and cardiovascular fat depots were quantified by electron beam CT. Outcomes were presence of CAC (none vs. any: Agatston score >0), and severity of CAC (CAC Agatston score). Logistic and tobit regression were used. Final models were adjusted for age, race, study site, menopausal status, obesity (BMI ≥30 Kg/m 2 ), systolic blood pressure, lipids, homeostasis model assessment insulin resistance index, current smoking, physical activity, comorbidity (history of hypertension, stroke, angina, heart attack or diabetes) and medication use (cholesterol lowering, antihypertensive or antidiabetic medications). Results: The study included 509 women (37.9% black; 58.4% pre-/early perimenopausal, 41.6% late peri-/postmenopausal) aged 46-59 years with data on any of the 4 fat depots. CAC was found in 47.4% of the participants. Odds ratios (95% CI) from final logistic regression models showed that higher volumes of EAT (2.43 (1.22, 4.86), PAT (1.57 (1.04, 2.37), and TAT (2.43 (1.22, 4.87), were significantly associated with higher odds of presence of CAC. Similarly, tobit regression models showed that higher volumes per 1 log-unit increase of EAT (β (SE): 28.0 (10.7)), PAT (16.5 (6.6)), and TAT (30.0 (10.7)), were significantly associated with greater severity of CAC in final adjusted models. PVAT was not associated with either CAC presence or severity in final models. Conclusions: Heart fat (EAT, PAT and TAT), but not peri-aortic fat were independently associated with greater presence and severity of CAC in women at midlife, suggesting that local cardiovascular fat depots may contribute to CAD in midlife women. Future work is warranted to understand the underlying mechanistic pathways.

AimWe aimed to detect the individual and combined effect of glucose metabolic components on cognitive function in particular domains among older adults.MethodsData of 2,925 adults aged over 60 years from the 2011 to 2014 National Health and Nutrition Examination Survey were analyzed. Individuals’ cognitive function was evaluated using the Digit Symbol Substitution Test (DSST), the Animal Fluency Test (AF), the Consortium to Establish a Registry for Alzheimer’s Disease Immediate Recall (CERAD-IR), and CERAD Delayed Recall (CERAD-DR). Participants’ glucose metabolic health status was determined based on fasting plasma glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), glycated hemoglobin (HbA1c), and 2-h postload glucose. Linear regression models were used to delineate the associations of cognitive function with individual glucose metabolic component and with metformin use. Logistic regression models were performed to evaluate the associations of cognition with the number of glucose metabolic risk components.ResultsCERAD-IR was significantly associated with HOMA-IR and insulin. HbA1c was related to all the cognitive tests except AF. Among participants without obesity, HOMA-IR and insulin were both negatively associated with CERAD-IR and CERAD-DR. Odds of scoring low in DSST increased with the number of glucose metabolic risk components (odds ratio 1.94, 95% confidence interval [CI] 1.26 to 2.98). Metformin use was associated with better performance in DSST among diabetes patients (β = 4.184, 95% CI 1.655 to 6.713).ConclusionsOur findings support the associations of insulin resistance and glycemic level with cognitive function in key domains, especially among adults without obesity. There is a positive association between metformin use and cognition.

Introduction: Ideal cardiovascular health (CVH), as defined by American Heart Association (AHA), is associated with low levels of cardiovascular disease (CVD) risk factors and freedom from coronary artery calcium (CAC). Hypothesis: Baseline ideal CVH predicts freedom from CAC progression. Methods: In the Framingham Heart Study (FHS), we evaluated prevalence of ideal CVH and investigated associations between ideal CVH and CAC progression. We included 1969 participants who attended the first and second rounds of the FHS Multi-Detector Computed Tomography study (MDCT-I and MDCT-II). The presence and burden of calcification was defined by a modified Agatston score. We calculated the repeatability of two CAC readings performed during MDCT-I and quantified the uncertainty estimate to define CAC progression. At follow-up, an increase in CAC score of 3.4 or higher was defined as positive CAC progression for those free of CAC at baseline. Using criteria modified from the AHA’s Strategic Impact Goal, we defined the prevalence of poor, intermediate and ideal CVH using five of the seven metrics: blood pressure, total-cholesterol, cigarette smoking, body mass index, and fasting glucose. For each metric of CVH, we assigned a score of 0, 1, and 2 points for poor, intermediate, and ideal CVH, respectively, to quantify CVH and extent of change in ideal CVH. Baseline age, baseline CVH status, and change in CVH category were independent variables for logistic regression models to test significant associations between CAC progression and change in ideal CVH. Results: The prevalence of ideal, intermediate, and poor CVH for 1148 participants who were free of baseline CAC were 15.77%, 43.73%, 40.51%, respectively. After an average 6.1 years of follow-up, the prevalence of ideal, intermediate, and poor CVH changed to 6.5%, 43.4%, and 50.1%, respectively, while the CAC progression rates were 8.0%, 13.1%, and 21.6%, respectively. In logistic regression models, there was a non-significant trend for CAC progression by CVH group. Compared to those with poor CVH at baseline, the presence of ideal CVH at baseline was significantly protective against the occurrence of CAC progression; the hazard ratio (HR) for occurrence of CAC progression was 0.36 (95%C.I. 0.19, 0.66, p<0.001). Compared to those with intermediate CVH, there was potential protection against CAC progression, although the HR 0.66 was not statistically significant (95%C.I. 0.36, 1.21, p=0.62). Conclusions: In a community-based study, we observed significant protection from progression of CAC at follow-up for participants who were free of CAC with ideal CVH at baseline. These findings support continued public health measures to promote ideal CVH.

Objective: Mounting evidence demonstrates a role of ectopic cardiovascular fat (ECF), which surrounds the heart and vasculature, in the pathogenesis of cardiovascular disease (CVD). It is unknown whether ECF depots are related to atherosclerotic burden in women transitioning through menopause, a time of increasing CVD risk. We evaluated the cross-sectional associations between volumes of epicardial (EAT), pericardial (PAT), total heart (TAT; TAT=EAT+PAT) and perivascular (peri-aortic) (PVAT) adipose tissues and aortic calcification (AC) in a sample of white and black midlife women. Effect modifications by race and menopausal status were also examined. Design: Data were obtained from the SWAN ectopic cardiovascular fat ancillary study. AC and ECF depots were quantified by electron beam computed tomography. Outcomes were presence of AC among all women, and extent of AC among women with an Agatston score >0. Logistic and linear regression were used as appropriate. Final models were adjusted for age, race, study site, menopausal status, body mass index (BMI), systolic blood pressure, lipids and insulin resistance. Results: The study included 257 women (32.7% Black; 58.7% pre-/early peri-menopausal and 41.3% late peri-/postmenopausal) aged 46-58 years with data on any of the 4 ECF depots (EAT, PAT and TAT: n=227, PVAT: n=191). AC was found in 184 (71.6%) participants. Pre-/early peri menopausal women had less EAT (median (Q1, Q3): 35.0 (28.4, 51.7) cm 3 vs. 43.5 (32.9, 58.3) cm 3 , P = 0.02) and TAT (median (Q1, Q3): 42.5 (33.2, 64.5) cm 3 vs. 50.3 (38.9, 74.3) cm 3 , P = 0.05) than late peri-/postmenopausal women, respectively. In final models, only EAT (OR (95%CI): 3.29 (1.14, 9.54)) was associated with higher odds of presence of AC. Interactions with race or menopausal status were not significant. Relationships between ECF depots (EAT,PAT and TAT) and extent of AC varied by race (all P <0.05); in that higher volumes of EAT, PAT and TAT were associated with greater AC in black compared with white women in final models. Irrespective of race or menopausal status, higher volumes of PVAT (β (SE): 1.60 (0.63), P= 0.01, per 1 log-unit increase in PVAT) were associated with greater extent of AC in the fully adjusted model. In black women only, the associations of PAT and TAT with extent of AC varied by menopausal status (all P <0.05) independent of age, BMI and other CVD risk factors: late peri-/postmenopausal women had significantly more AC than pre-/early peri-menopausal women for each 1-log unit increase in PAT (β (SE): 1.57 (0.66), P=0.02) and TAT (β (SE): 2.29 (1.04), P=0.03). Conclusion: ECF depots are associated with aortic calcification in women at midlife and the associations vary by race and menopausal status. Perhaps ECF plays a role in the higher risk of CVD reported in women after menopause.

Background: The location and quantity of specific adipose tissue depots have been shown to be independent predictors of subclinical atherosclerosis. Most recently, attention has been focused on the quality of these fat depots as a novel marker of CVD risk. Adipose tissue attenuation, measured via radiodensity in computed tomography (CT) Hounsfield units (HU), is one such marker of fat quality. Our objective was to determine the cross-sectional association between total heart adipose tissue (TAT) radiodensity and coronary artery calcification (CAC) in women at midlife, a time period marked with an increase in CVD risk. Methods: Participants from the Study of Women’s Health Across the Nation (SWAN) Ectopic Cardiovascular Fat Ancillary Study were evaluated. CAC and TAT were measured using electron-beam CT. CAC was evaluated as 1) presence of CAC (CAC Agatston score >10), and 2) extent of CAC (continuous Agatston score). TAT radiodensity was evaluated as tertiles of HU (lowest tertile, -91 to -81 HU; middle tertile, -80 to -78 HU; highest tertile -77 to -67 HU). Logistic (for CAC presence) and Tobit regression (for CAC extent) were used for statistical analyses. Results: A total of 495 women with a mean age of 51 years were examined. This sample of women was 63% white, 37% black, 54% pre-/early peri-menopausal, 35% late peri-/postmenopausal, and 11% used hormones. In unadjusted logistic and Tobit regression models ( Table 1 ), the tertiles of TAT were significantly and inversely associated with the presence and extent of CAC. In fully adjusted models, the middle tertile remained significantly inversely associated with the presence and extent of CAC compared to the lowest tertile, but the adjusted estimates for the highest tertile were attenuated and non-significant ( Table 1 ). Conclusions: There appears to be an inverse relationship between TAT radiodensity and CAC which is more pronounced for those with mid-range radiodensity values. These results merit further investigation.

The Impact

Objective: While the use of intraoperative laser angiography (SPY) is increasing in mastectomy patients, its impact in the operating room to change the type of reconstruction performed has not been well described. The purpose of this study is to investigate whether SPY angiography influences post-mastectomy reconstruction decisions and outcomes. Methods and materials: A retrospective analysis of mastectomy patients with reconstruction at a single institution was performed from 2015-2017.All patients underwent intraoperative SPY after mastectomy but prior to reconstruction. SPY results were defined as ‘good’, ‘questionable’, ‘bad’, or ‘had skin excised’. Complications within 60 days of surgery were compared between those whose SPY results did not change the type of reconstruction done versus those who did. Preoperative and intraoperative variables were entered into multivariable logistic regression models if significant at the univariate level. A p-value <0.05 was considered significant. Results: 267 mastectomies were identified, 42 underwent a change in the type of planned reconstruction due to intraoperative SPY results. Of the 42 breasts that underwent a change in reconstruction, 6 had a ‘good’ SPY result, 10 ‘questionable’, 25 ‘bad’, and 2 ‘had areas excised’ (p<0.01). After multivariable analysis, predictors of skin necrosis included patients with ‘questionable’ SPY results (p<0.01, OR: 8.1, 95%CI: 2.06 – 32.2) and smokers (p<0.01, OR:5.7, 95%CI: 1.5 – 21.2). Predictors of any complication included a change in reconstruction (p<0.05, OR:4.5, 95%CI: 1.4-14.9) and ‘questionable’ SPY result (p<0.01, OR: 4.4, 95%CI: 1.6-14.9). Conclusion: SPY angiography results strongly influence intraoperative surgical decisions regarding the type of reconstruction performed. Patients most at risk for flap necrosis and complication post-mastectomy are those with questionable SPY results.

Aim: To identify demographic predictors of patients who miss oncology follow-up, considering that missed follow-up has not been well studies in cancer patients. Methods: Patients with solid tumors diagnosed from 2007 to 2016 were analyzed (n = 16,080). Univariate and multivariable logistic regression models were constructed to examine predictors of missed follow-up. Results: Our study revealed that 21.2% of patients missed ≥1 follow-up appointment. African–American race (odds ratio [OR] 1.33; 95% CI: 1.17–1.51), Medicaid insurance (OR 1.59; 1.36–1.87), no insurance (OR 1.66; 1.32–2.10) and rural residence (OR 1.78; 1.49–2.13) were associated with missed follow-up. Conclusion: Many cancer patients miss follow-up, and inadequate follow-up may influence cancer outcomes. Further research is needed on how to address disparities in follow-up care in high-risk patients.

Predictors Of Adherence

Since March 2020, the Cameroonian government implemented nationwide measures to stall COVID-19 transmission. However, little is known about how well these unprecedented measures are being observed as the pandemic evolves. We conducted a six-month online survey to assess the preventive behaviour of Cameroonian adults during the COVID-19 outbreak. A five-point adherence score was constructed based on self-reported observance of the following preventive measures: physical distancing, face mask use, hand hygiene, not touching one’s face, and covering the mouth when coughing or sneezing. Predictors of adherence were investigated using ordinal logistic regression models. Of the 7381 responses received from all ten regions, 73.3% were from male respondents and overall mean age was 32.8 ± 10.8 years. Overall mean adherence score was 3.96 ± 1.11 on a scale of 0–5. Mean weekly adherence scores were initially high, but gradually decreased over time accompanied by increasing incidence of COVID-19 during the last study weeks. Predictors for higher adherence included higher age, receiving COVID-19 information from health personnel, and agreeing with the necessity of lockdown measures. Meanwhile, experiencing flu-like symptoms was associated with poor adherence. Continuous observance of preventive measures should be encouraged among Cameroonians in the medium- to long-term to avoid a resurgence in COVID-19 infections.

Vaccine Information

There is a critical need for the public to have trusted sources of vaccine information. A longitudinal online study assessed trust in COVID-19 vaccine information from 10 sources. A factor analysis for data reduction revealed two factors. The first factor contained politically conservative sources (PCS) of information. The second factor included eight news sources representing mainstream sources (MS). Multivariable logistic regression models were used. Trust in Dr. Fauci was also examined. High trust in MS was associated with intention to encourage family members to get COVID-19 vaccines, altruistic beliefs that more vulnerable people should have vaccine priority, and belief that racial minorities with higher rates of COVID-19 deaths should have priority. High trust in PCS was associated with intention to discourage friends from getting vaccinated. Higher trust in PCS was also associated with participants more likely to disagree that minorities with higher rates of COVID-19 deaths should have priority for a vaccine. High trust in Dr. Fauci as a source of COVID-19 vaccine information was associated with factors similar to high trust in MS. Fair, equitable, and transparent access and distribution are essential to ensure trust in public health systems’ abilities to serve the population.

Abstract Purpose To test the effect of anatomic variants of the prostatic apex overlapping the membranous urethra (Lee type classification), as well as median urethral sphincter length (USL) in preoperative multiparametric magnetic resonance imaging (mpMRI) on the very early continence in open (ORP) and robotic-assisted radical prostatectomy (RARP) patients. Methods In 128 consecutive patients (01/2018–12/2019), USL and the prostatic apex classified according to Lee types A–D in mpMRI prior to ORP or RARP were retrospectively analyzed. Uni- and multivariable logistic regression models were used to identify anatomic characteristics for very early continence rates, defined as urine loss of ≤ 1 g in the PAD-test. Results Of 128 patients with mpMRI prior to surgery, 76 (59.4%) underwent RARP vs. 52 (40.6%) ORP. In total, median USL was 15, 15 and 10 mm in the sagittal, coronal and axial dimensions. After stratification according to very early continence in the PAD-test (≤ 1 g vs. > 1 g), continent patients had significantly more frequently Lee type D (71.4 vs. 54.4%) and C (14.3 vs. 7.6%, p = 0.03). In multivariable logistic regression models, the sagittal median USL (odds ratio [OR] 1.03) and Lee type C (OR: 7.0) and D (OR: 4.9) were independent predictors for achieving very early continence in the PAD-test. Conclusion Patients’ individual anatomical characteristics in mpMRI prior to radical prostatectomy can be used to predict very early continence. Lee type C and D suggest being the most favorable anatomical characteristics. Moreover, longer sagittal median USL in mpMRI seems to improve very early continence rates.
