Response to letters-to-the-editor for publication: "Defect-free care trends in the Paul Coverdell National Acute Stroke Program (PCNASP), 2008-2018. American Heart Journal. 2021;232:177-184. doi:10.1016/j.ahj.2020.11.010."
Overwyk K , Yin X , Tong X , Coleman King SM , Wiltz JL . Am Heart J 2021 236 112 Thank you for your letter. We recognize that stroke-related laws, policies, and funding vary by state, which impacts the provision of stroke care. Centers for disease control and prevention (CDC’s) Division for Heart Disease and Stroke Prevention has posted resources on stroke-related state policy and capacity at https://www.cdc.gov/dhdsp/pubs/stroke_resources.htm. We also recently published a report1 on evidence-supported state laws to advance stroke care. State-level data from nine funded states drive the Paul Coverdell National Acute Stroke Program’s (PCNASP’s) activities. For example, each PCNASP state receives quarterly reports on its quality improvement activities, and state summaries for each funding cycle and state success stories are shared publicly.2, 3 | | We appreciate Steven Thomas’s comment about evaluating stroke care during the current pandemic. PCNASP’s support for data collection to improve the quality of stroke care in its nine funded states is ongoing through the pandemic and into the future.4, 5 Additionally, national dissemination of the funded states’ successes helps extend these lessons beyond the Coverdell experience. |

Alzheimers Dement 2022 19 (2) 391-404 We propose the hypothesis that small high-density lipoprotein (HDL) particles reduce the risk of Alzheimer's disease (AD) by virtue of their capacity to exchange lipids, affecting neuronal membrane composition and vascular and synaptic functions. Concentrations of small HDLs in cerebrospinal fluid (CSF) and plasma were measured in 180 individuals ≥60 years of age using ion mobility methodology. Small HDL concentrations in CSF were positively associated with performance in three domains of cognitive function independent of apolipoprotein E (APOE) ε4 status, age, sex, and years of education. Moreover, there was a significant correlation between levels of small HDLs in CSF and plasma. Further studies will be aimed at determining whether specific components of small HDL exchange across the blood, brain, and CSF barriers, and developing approaches to exploit small HDLs for therapeutic purposes. |
Long-Term Symptoms Among Adults Tested for SARS-CoV-2 - United States, January 2020-April 2021.
Wanga V , Chevinsky JR , Dimitrov LV , Gerdes ME , Whitfield GP , Bonacci RA , Nji MAM , Hernandez-Romieu AC , Rogers-Brown JS , McLeod T , Rushmore J , Lutfy C , Bushman D , Koumans E , Saydah S , Goodman AB , Coleman King SM , Jackson BR , Cope JR . MMWR Morb Mortal Wkly Rep 2021 70 (36) 1235-1241 Long-term symptoms often associated with COVID-19 (post-COVID conditions or long COVID) are an emerging public health concern that is not well understood. Prevalence of post-COVID conditions has been reported among persons who have had COVID-19 (range = 5%-80%), with differences possibly related to different study populations, case definitions, and data sources (1). Few studies of post-COVID conditions have comparisons with the general population of adults with negative test results for SARS-CoV-2, the virus that causes COVID-19, limiting ability to assess background symptom prevalence (1). CDC used a nonprobability-based Internet panel established by Porter Novelli Public Services* to administer a survey to a nationwide sample of U.S. adults aged ≥18 years to compare the prevalence of long-term symptoms (those lasting >4 weeks since onset) among persons who self-reported ever receiving a positive SARS-CoV-2 test result with the prevalence of similar symptoms among persons who reported always receiving a negative test result. The weighted prevalence of ever testing positive for SARS-CoV-2 was 22.2% (95% confidence interval [CI] = 20.6%-23.8%). Approximately two thirds of respondents who had received a positive test result experienced long-term symptoms often associated with SARS-CoV-2 infection. Compared with respondents who received a negative test result, those who received a positive test result reported a significantly higher prevalence of any long-term symptom (65.9% versus 42.9%), fatigue (22.5% versus 12.0%), change in sense of smell or taste (17.3% versus 1.7%), shortness of breath (15.5% versus 5.2%), cough (14.5% versus 4.9%), headache (13.8% versus 9.9%), and persistence (>4 weeks) of at least one initially occurring symptom (76.2% versus 69.6%). Compared with respondents who received a negative test result, a larger proportion of those who received a positive test result reported believing that receiving a COVID-19 vaccine made their long-term symptoms better (28.7% versus 15.7%). Efforts to address post-COVID conditions should include helping health care professionals recognize the most common post-COVID conditions and optimize care for patients with persisting symptoms, including messaging on potential benefits of COVID-19 vaccination. |
Contemporary trends in the treatment of mild ischemic stroke with intravenous thrombolysis: Paul Coverdell National Acute Stroke Program
Asaithambi G , Tong X , Coleman King SM , George MG . Cerebrovasc Dis 2021 51 (1) 60-66 Background: Presentation with mild symptoms is a common reason for intravenous thrombolysis (IVT) nonuse among acute ischemic stroke (AIS) patients. We examined the impact of IVT on the outcomes of mild AIS over time. Methods: Using the Paul Coverdell National Stroke Program data, we examined trends in IVT utilization from 2010 to 2019 among AIS patients presenting with National Institutes of Health Stroke Scale (NIHSS) scores ≤5. Outcomes adjudicated included rates of discharge to home and ability to ambulate independently at discharge. We used generalized estimating equation models to examine the effect of IVT on outcomes of AIS patients presenting with mild symptoms and calculated adjusted odds ratio (AOR) with 95% confidence intervals (CI). Results: During the study period, 346,762 patients presented with mild AIS symptoms. Approximately 6.2% were treated with IVT. IVT utilization trends increased from 3.7% in 2010 to 7.7% in 2019 (p < 0.001). Patients treated with IVT had higher median NIHSS scores upon presentation (IVT 3 [2, 4] vs. no IVT 2 [0, 3]). Rates of discharge to home (AOR 2.06, 95% CI: 1.99-2.13) and ability to ambulate at time of discharge (AOR 1.82, 95% CI: 1.76-1.89) were higher among those treated with IVT. Conclusion: There was an increased trend in IVT utilization among AIS patients presenting with mild symptoms. Utilization of IVT increased the odds of being discharged to home and the ability to ambulate at discharge independently in patients with mild stroke. © 2021 The Author(s). Published by S.

Real-Time CDC Consultation during the COVID-19 Pandemic-United States, March-July, 2020.
Wozniczka D , Demeke HB , Thompson-Paul AM , Ijeoma U , Williams TR , Taylor AW , Tan KR , Chevalier MS , Agyemang E , Dowell D , Oduyebo T , Shiferaw M , Coleman King SM , Minta AA , Shealy K , Oliver SE , McLean C , Glover M , Iskander J . Int J Environ Res Public Health 2021 18 (14) Context: In response to the COVID-19 pandemic, the Centers for Disease Prevention and Control (CDC) clinicians provided real-time telephone consultation to healthcare providers, public health practitioners, and health department personnel. Objective: To describe the demographic and public health characteristics of inquiries, trends, and correlation of inquiries with national COVID-19 case reports. We summarize the results of real-time CDC clinician consultation service provided during 11 March to 31 July 2020 to understand the impact and utility of this service by CDC for the COVID-19 pandemic emergency response and for future outbreak responses. Design: Clinicians documented inquiries received including information about the call source, population for which guidance was sought, and a detailed description of the inquiry and resolution. Descriptive analyses were conducted, with a focus on characteristics of callers as well as public health and clinical content of inquiries. Setting: Real-time telephone consultations with CDC Clinicians in Atlanta, GA. Partic-ipants: Health care providers and public health professionals who called CDC with COVID-19 related inquiries from throughout the United States. Main Outcome Measures: Characteristics of inquiries including topic of inquiry, inquiry population, resolution, and demographic information. Results: A total of 3154 COVID-19 related telephone inquiries were answered in real-time. More than half (62.0%) of inquiries came from frontline healthcare providers and clinical sites, followed by 14.1% from state and local health departments. The majority of inquiries focused on issues in-volving healthcare workers (27.7%) and interpretation or application of CDC’s COVID-19 guidance (44%). Conclusion: The COVID-19 pandemic resulted in a substantial number of inquiries to CDC, with the large majority originating from the frontline clinical and public health workforce. Analysis of inquiries suggests that the ongoing focus on refining COVID-19 guidance documents is war-ranted, which facilitates bidirectional feedback between the public, medical professionals, and public health authorities. © 2021 by the authors.

Effect of insurance status on outcomes of acute ischemic stroke patients receiving intra-arterial treatment: Results from the Paul Coverdell National Acute Stroke Program
Asaithambi G , Tong X , Lakshminarayan K , Coleman King SM , George MG . J Stroke Cerebrovasc Dis 2021 30 (5) 105692 BACKGROUND: Stroke continues to be a leading cause of death and disability in the United States. Rates of intra-arterial reperfusion treatments (IAT) for acute ischemic stroke (AIS) are increasing, and these treatments are associated with more favorable outcomes. We sought to examine the effect of insurance status on outcomes for AIS patients receiving IAT within a multistate stroke registry. METHODS: We used data from the Paul Coverdell National Acute Stroke Program (PCNASP) from 2014 to 2019 to quantify rates of IAT (with or without intravenous thrombolysis) after AIS. We modeled outcomes based on insurance status: private, Medicare, Medicaid, or no insurance. Outcomes were defined as rates of discharge to home, in-hospital death, symptomatic intracranial hemorrhage (sICH), or life-threatening hemorrhage during hospitalization. RESULTS: During the study period, there were 486,180 patients with a clinical diagnosis of AIS (mean age 70.6 years, 50.3% male) from 674 participating hospitals in PCNASP. Only 4.3% of patients received any IAT. As compared to private insurance, uninsured patients receiving any IAT were more likely to experience in-hospital death (AOR 1.36 [95% CI 1.07-1.73]). Medicare (AOR 0.78 [95% CI 0.71-0.85]) and Medicaid (AOR 0.85 [95% CI 0.75-0.96]) beneficiaries were less likely but uninsured patients were more likely (AOR 1.90 [95% CI 1.61-2.24]) to be discharged home. Insurance status was not found to be independently associated with rates of sICH. CONCLUSIONS: Insurance status was independently associated with in-hospital death and discharge to home among AIS patients undergoing IAT. |
Emergency medical services utilization for acute stroke care: Analysis of the Paul Coverdell National Acute Stroke Program, 2014-2019
Asaithambi G , Tong X , Lakshminarayan K , Coleman King SM , George MG , Odom EC . Prehosp Emerg Care 2021 26 (3) 1-9 OBJECTIVE: Emergency medical service (EMS) transportation after acute stroke is associated with shorter symptom-to-arrival times and more rapid medical attention when compared to patient transportation by private vehicle. METHODS: We analyzed data from the Paul Coverdell National Acute Stroke Program from 2014 to 2019 among stroke (ischemic and hemorrhagic) and transient ischemic attack (TIA) patients to examine patterns in EMS utilization. RESULTS: Of 500,829 stroke and TIA patients (mean age 70.9 years, 51.3% women) from 682 participating hospitals during the study period, 60% arrived by EMS. Patients aged 18-64 years vs. ≥65 years (AOR 0.67) were less likely to utilize EMS. Severe stroke patients (AOR 2.29, 95%CI, 2.15-2.44) and hemorrhagic stroke patients vs. ischemic stroke patients (AOR 1.47, 95% CI, 1.43-1.51) were more likely to utilize EMS. Medicare (AOR 1.35, 95% CI, 1.32-1.38) and Medicaid (AOR 1.41, 95% CI, 1.37-1.45) beneficiaries were more likely than privately insured patients to utilize EMS, but no difference was found between no insurance/self-pay patients and privately insured patients on EMS utilization. Overall, there was a decreasing trend in the utilization of EMS (59.6% to 59.3%, p = 0.037). The decreasing trend was identified among ischemic stroke (p < 0.0001) patients but not among TIA (p = 0.89) or hemorrhagic stroke (p = 0.44) patients. There was no observed trend in pre-notification among stroke patients' arrival by EMS across the study period (56.9% to 56.5%, p = 0.99). CONCLUSIONS: Strategies to help increase stroke awareness and utilization of EMS among those with symptoms of stroke should be considered in order to help improve stroke outcomes. |

Nwankwo T , Coleman King SM , Ostchega Y , Zhang G , Loustalot F , Gillespie C , Chang TE , Begley EB , George MG , Shimbo D , Schwartz JE , Muntner P , Kronish IM , Hong Y , Merritt R . Am J Hypertens 2020 33 (11) 1021-1029 BACKGROUND: The U.S. Preventive Services Task Force recommends the use of 24-hour ambulatory blood pressure monitoring (ABPM) as part of screening and diagnosis of hypertension. The optimal ABPM device for population-based surveys is unknown. OBJECTIVE: Among three ABPM devices, we compared the proportion of valid BP readings, mean awake and asleep BP readings, differences between awake ABPM readings and initial standardized BP readings, and sleep experience. RESULTS: The proportions of valid blood pressure readings were not different among the three devices ( p > 0.45). Mean awake and asleep systolic BP were significantly higher for STO device (WA vs. STO vs. SL: 126.65 mmHg, 138.09 mmHg, 127.44 mmHg; 114.34 mmHg, 120.34 mmHg, 113.13 mmHg; p <0.0001 for both). The difference between the initial average standardized mercury systolic BP readings and the ABPM mean awake systolic BP was larger for STO device (WA vs. STO. vs. SL: -5.26 mmHg, -16.24 mmHg, -5.36 mmHg; p <0.0001); diastolic BP mean differences were ~ -6 mmHg for all three devices ( p =0.6). Approximately 55% of participants reported that the devices interfered with sleep; however, there were no sleep differences across the devices (p >0.4 for all). CONCLUSION: Most of the participants met the threshold of 70% valid readings over 24 hours. Sleep disturbance was common but did not interfere with completion of measurement in most of the participants. |
Trends in hospital procedure volumes for intra-arterial treatment of acute ischemic stroke: results from the Paul Coverdell National Acute Stroke Program
Asaithambi G , Tong X , Lakshminarayan K , Coleman King SM , George MG . J Neurointerv Surg 2020 12 (11) 1076-1079 BACKGROUND: Rates of intra-arterial revascularization treatments (IAT) for acute ischemic stroke (AIS) are increasing in the USA. Using a multi-state stroke registry, we studied the trend in IAT use among patients with AIS over a period spanning 11 years. We examined the impact of IAT rates on hospital procedure volumes and patient outcome after stroke. METHODS: We used data from the Paul Coverdell National Acute Stroke Program (PCNASP) and explored trends in IAT between 2008 and 2018. Patient outcomes were examined by rates of IAT procedures across hospitals. Specifically, outcomes were compared across low-volume (<15 IAT per year), medium-volume (15-30 IAT per year), and high-volume hospitals (>30 IAT per year). Favorable outcome was defined as discharge to home. RESULTS: There were 612 958 patients admitted with AIS to 687 participating hospitals within the PCNASP during this study. Only 2.9% of patients (mean age 68.5 years, 49.3% women) received IAT. The percent of patients with AIS receiving IAT increased from 1% in 2008 to 5.3% in 2018 (p<0.001). The proportion of low-volume hospitals decreased over time (p<0.001), and the proportions of medium-volume (p=0.007) and high-volume hospitals (p<0.001) increased between 2008 and 2018. When compared with medium-volume hospitals, high-volume hospitals had a higher (p<0.0001) and low-volume hospitals had a lower (p<0.0001) percent of patients discharged to home. CONCLUSION: High-volume hospitals were associated with a higher rate of favorable outcome. With the increased use of IAT among patients with AIS, the proportion of low-volume hospitals performing IAT significantly decreased. |
Current trends in the acute treatment of ischemic stroke: analysis from the Paul Coverdell National Acute Stroke Program
Asaithambi G , Tong X , Lakshminarayan K , Coleman King SM , George MG . J Neurointerv Surg 2019 12 (6) 574-578 BACKGROUND: The intra-arterial treatment (IAT) of acute ischemic stroke (AIS) is now evidence-based and given the highest level of recommendation among eligible patients. Using a multi-state stroke registry, we studied the trend in IAT among patients with AIS over 11 years and its impact on the utilization of intravenous thrombolysis (IVT) within the same 11 years. METHODS: Using data from the Paul Coverdell National Acute Stroke Program (PCNASP), we studied trends in IVT and IAT for patients with AIS between 2008 and 2018. Trends over time were examined for rates of IVT only, IAT only, or a combination of IVT and IAT (IVT+IAT). Favorable outcome was defined as discharge to home. RESULTS: During the study period there were 595 677 patients (mean age 70.4 years, 50.4% women) from 646 participating hospitals with a clinical diagnosis of AIS in the PCNASP. Trends for IVT only, IAT only, and IVT+IAT all significantly increased over time (P<0.001). Total use of IVT and IAT increased from 7% in 2008 to 19.1% in 2018. The rate of patients discharged to home increased significantly over time among all treatment groups (P<0.001). CONCLUSION: In our large registry-based analysis, we observed a significant increase in the use of IAT for the treatment of AIS, with continued increases in the use of IVT. Concurrently, the percent of patients with favorable outcomes continued to increase. |
Trends and factors associated with concordance between International Classification of Diseases, Ninth and Tenth Revision, Clinical Modification Codes and stroke clinical diagnoses
Chang TE , Tong X , George MG , Coleman King SM , Yin X , O'Brien S , Ibrahim G , Liskay A , Wiltz JL . Stroke 2019 50 (8) Strokeaha118024092 Background and Purpose- International Classification of Diseases, Ninth and Tenth Revision, Clinical Modification ( ICD-9-CM and ICD-10-CM) codes are often used for disease surveillance. We examined changes in concordance between ICD-CM codes and clinical diagnoses before and after the transition to ICD-10-CM in the United States (October 1, 2015), and determined if there were systematic variations in concordance by patient and hospital characteristics. Methods- We included Paul Coverdell National Acute Stroke Program patient discharges from 2014 to 2017. Concordance between ICD-CM codes and the clinical diagnosis documented by the physician (assumed as accurate) was calculated for each diagnosis category: ischemic stroke, transient ischemic attack, subarachnoid hemorrhage, and intracerebral hemorrhage. Results- In total, 314 857 patient records were included in the analysis (n=280 hospitals), 55.9% of which were obtained after the transition to ICD-10-CM. While concordance was generally high, a small, and temporary decline occurred from the last calendar quarter of ICD-9-CM (average unadjusted concordance =92.8%) to the first quarter of ICD-10-CM use (91.0%). Concordance differed by diagnosis category and was generally highest for ischemic stroke. In the analysis of ICD-10-CM records, disagreements often occurred between ischemic stroke and transient ischemic attack records and between subarachnoid and intracerebral hemorrhage records. Compared with the smallest hospitals (</=200 beds), larger hospitals had significantly higher odds of concordance (ischemic stroke adjusted odds ratio for >/=400 beds, 1.7; 95% CI, 1.5-1.9). Conclusions- This study identified a small and transient decline in concordance between ICD-CM codes and stroke clinical diagnoses during the coding transition, indicating no substantial impact on the overall identification of stroke patients. Researchers and policymakers should remain aware of potential changes in ICD-CM code accuracy over time, which may affect disease surveillance. Systematic variations in the accuracy of codes by hospital and patient characteristics have implications for quality-of-care studies and hospital comparative assessments. |
A decade of improvement in door-to-needle time among acute ischemic stroke patients, 2008 to 2017
Tong X , Wiltz JL , George MG , Odom EC , Coleman King SM , Chang T , Yin X , Merritt RK . Circ Cardiovasc Qual Outcomes 2018 11 (12) e004981 BACKGROUND: The clinical benefit of intravenous (IV) alteplase in acute ischemic stroke is time dependent. We assessed the overall temporal changes in door-to-needle (DTN) time and examine the factors associated with DTN time </=60 and </=45 minutes. METHODS AND RESULTS: A total of 496 336 acute ischemic stroke admissions were identified in the Paul Coverdell National Acute Stroke Program from 2008 to 2017. We used generalized estimating equations models to examine the factors associated with DTN time </=60 and </=45 minutes, and calculated adjusted odds ratios and 95% CI. Between 2008 and 2017, the percentage of acute ischemic stroke patients who received IV alteplase including those transferred, increased from 6.4% to 15.3%. After excluding those who received IV alteplase at an outside hospital, a total of 39 737 (8%) acute ischemic stroke patients received IV alteplase within 4.5 hours of the time the patient last known to be well. Significant increases were seen in DTN time </=60 minutes (26.4% in 2008 to 66.2% in 2017, P<0.001), as well as DTN time </=45 minutes (10.7% in 2008 to 40.5% in 2017, P<0.001). Patients aged 55 to 84 years were more likely to receive IV alteplase within 60 minutes, while those aged 55 to 74 years were more likely to receive IV alteplase within 45 minutes, as compared with those aged 18 to 54 years. Arrival by emergency medical service, and patients with severe stroke were more likely to receive IV alteplase within 60 and 45 minutes. Conversely, women, black patients as compared with white, and patients with a medical history of diseases associated with stroke were less likely to receive DTN time </=60 or 45 minutes. CONCLUSIONS: Rapid improvements in DTN time were observed in the Paul Coverdell National Acute Stroke Program; however, opportunities to reduce disparities remain. |
Association between urinary sodium and potassium excretion and blood pressure among adults in the United States: National Health and Nutrition Examination Survey, 2014
Jackson SL , Cogswell ME , Zhao L , Terry AL , Wang CY , Wright J , Coleman King SM , Bowman B , Chen TC , Merritt RK , Loria CM . Circulation 2017 137 (3) 237-246 Background -Higher levels of sodium and lower levels of potassium intake are associated with higher blood pressure. However, the shape and magnitude of these associations can vary by study participant characteristics or intake assessment method. Twenty-four hour urinary excretion of sodium and potassium are unaffected by recall errors and represent all sources of intake, and were collected for the first time in a nationally representative US survey. Our objective was to assess the associations of blood pressure and hypertension with 24-hour urinary excretion of sodium and potassium among US adults. Methods -Cross-sectional data from 766 participants aged 20-69 years with complete blood pressure and 24-hour urine collections in the 2014 National Health and Nutrition Examination Survey, a nationally-representative survey of the US noninstitutionalized population. Usual 24-hour urinary electrolyte excretion (sodium, potassium, and their ratio) was estimated from up to two collections on non-consecutive days, adjusting for day-to-day variability in excretion. Outcomes included systolic and diastolic blood pressure from the average of 3 measures and hypertension status, based on average blood pressure ≥140/90 and anti-hypertensive medication use. Results -After multivariable adjustment, each 1000 mg difference in usual 24-hour sodium excretion was directly associated with systolic (4.58 mmHg, 95% confidence interval 2.64,6.51) and diastolic (2.25 mmHg, 95% CI 0.83,3.67) blood pressures. Each 1000 mg difference in potassium excretion was inversely associated with systolic blood pressure (-3.72 mmHg, 95% CI -6.01,-1.42). Each 0.5 unit difference in sodium-to-potassium ratio was directly associated with systolic blood pressure (1.72 mmHg, 95% CI 0.76, 2.68). Hypertension was linearly associated with progressively higher sodium and lower potassium excretion; compared with the lowest quartiles of excretion, the adjusted odds of hypertension for the highest quartiles were 4.22 (95% CI 1.36, 13.15) for sodium, and 0.38 (95% CI 0.17, 0.87) for potassium, respectively, P<0.01 for trends. Conclusions -These cross-sectional results show a strong dose-response association between urinary sodium excretion and blood pressure, and an inverse association between urinary potassium excretion and blood pressure, in a nationally representative sample of US adults. |
Changes in primary healthcare providers' attitudes and counseling behaviors related to dietary sodium reduction, DocStyles 2010 and 2015
Quader ZS , Cogswell ME , Fang J , Coleman King SM , Merritt RK . PLoS One 2017 12 (5) e0177693 High blood pressure is a major risk factor for cardiovascular disease. The 2013 ACC/AHA Lifestyle Management Guideline recommends counseling pre-hypertensive and hypertensive patients to reduce sodium intake. Population sodium reduction efforts have been introduced in recent years, and dietary guidelines continued to emphasize sodium reduction in 2010 and 2015. The objective of this analysis was to determine changes in primary health care providers' sodium-reduction attitudes and counseling between 2010 and 2015. Primary care internists, family/general practitioners, and nurse practitioners answered questions about sodium-related attitudes and counseling behaviors in DocStyles, a repeated cross-sectional web-based survey in the United States. Differences in responses between years were examined. In 2015, the majority (78%) of participants (n = 1,251) agreed that most of their patients should reduce sodium intake, and reported advising hypertensive (85%), and chronic kidney disease patients (71%), but not diabetic patients (48%) and African-American patients (43%) to consume less salt. Since 2010, the proportion of participants agreeing their patients should reduce sodium intake decreased while the proportion advising patients with these characteristics to consume less salt increased and the prevalence of specific types of advice declined. Changes in behaviors between surveys remained significant after adjusting for provider and practice characteristics. More providers are advising patients to consume less salt in 2015 compared to 2010; however, fewer agree their patients should reduce intake and counseling is not universally applied across patient groups at risk for hypertension. Further efforts and educational resources may be required to enable patient counseling about sodium reduction strategies. |
Heart disease and cancer deaths - trends and projections in the United States, 1969-2020
Weir HK , Anderson RN , Coleman King SM , Soman A , Thompson TD , Hong Y , Moller B , Leadbetter S . Prev Chronic Dis 2016 13 E157 INTRODUCTION: Heart disease and cancer are the first and second leading causes of death in the United States. Age-standardized death rates (risk) have declined since the 1960s for heart disease and for cancer since the 1990s, whereas the overall number of heart disease deaths declined and cancer deaths increased. We analyzed mortality data to evaluate and project the effect of risk reduction, population growth, and aging on the number of heart disease and cancer deaths to the year 2020. METHODS: We used mortality data, population estimates, and population projections to estimate and predict heart disease and cancer deaths from 1969 through 2020 and to apportion changes in deaths resulting from population risk, growth, and aging. RESULTS: We predicted that from 1969 through 2020, the number of heart disease deaths would decrease 21.3% among men (-73.9% risk, 17.9% growth, 34.7% aging) and 13.4% among women (-73.3% risk, 17.1% growth, 42.8% aging) while the number of cancer deaths would increase 91.1% among men (-33.5% risk, 45.6% growth, 79.0% aging) and 101.1% among women (-23.8% risk, 48.8% growth, 76.0% aging). We predicted that cancer would become the leading cause of death around 2016, although sex-specific crossover years varied. CONCLUSION: Risk of death declined more steeply for heart disease than cancer, offset the increase in heart disease deaths, and partially offset the increase in cancer deaths resulting from demographic changes over the past 4 decades. If current trends continue, cancer will become the leading cause of death by 2020. |
Sodium in store and restaurant food environments - Guam, 2015
Jackson SL , VanFrank BK , Lundeen E , Uncangco A , Alam L , King SM , Cogswell ME . MMWR Morb Mortal Wkly Rep 2016 65 (20) 510-3 Compared with the United States overall, Guam has higher mortality rates from cardiovascular disease and stroke (1). Excess sodium intake can increase blood pressure and risk for cardiovascular disease (2,3). To determine the availability and promotion of lower-sodium options in the nutrition environment, the Guam Department of Public Health and Social Services (DPHSS) conducted an assessment in September 2015 using previously validated tools adapted to include sodium measures. Stores (N = 114) and restaurants (N = 63) were randomly sampled by region (north, central, and south). Data from 100 stores and 62 restaurants were analyzed and weighted to account for the sampling design. Across the nine product types assessed, lower-sodium products were offered less frequently than regular-sodium products (p<0.001) with <50% of stores offering lower-sodium canned vegetables, tuna, salad dressing, soy sauce, and hot dogs. Lower-sodium products were also less frequently offered in small stores than large (two or more cash registers) stores. Reduced-sodium soy sauce cost more than regular soy sauce (p<0.001) in stores offering both options in the same size bottle. Few restaurants engaged in promotion practices such as posting sodium information (3%) or identifying lower-sodium entrees (1%). Improving the availability and promotion of lower-sodium foods in stores and restaurants could help support healthier eating in Guam. |
Prevalence of excess sodium intake in the United States - NHANES, 2009-2012
Jackson SL , King SM , Zhao L , Cogswell ME . MMWR Morb Mortal Wkly Rep 2016 64 (52) 1393-7 Hypertension, a major risk factor for cardiovascular diseases, occurs among 29% of U.S. adults, and lowering excess sodium intake can reduce blood pressure (1-3). The 2015-2020 Dietary Guidelines for Americans recommend consuming less than 2,300 mg dietary sodium per day for persons aged ≥14 years and less for persons aged 2-13 years.* To examine the current prevalence of excess sodium intake among Americans overall, and among hypertensive adults, CDC analyzed data from 14,728 participants aged ≥2 years in the 2009-2012 National Health and Nutrition Examination Survey (NHANES). Eighty-nine percent of adults and over 90% of children exceeded recommendations for sodium intake. Among hypertensive adults, 86% exceeded 2,300 mg dietary sodium per day. To address the high prevalence of excess sodium consumption in the U.S. population, the Institute of Medicine (IOM) recommended reducing sodium in the food supply, as excess sodium added to foods during commercial processing and preparation represents the main source of sodium intake in U.S. diets (4). |
Health professional advice and adult action to reduce sodium intake
Jackson SL , Coleman King SM , Park S , Fang J , Odom EC , Cogswell ME . Am J Prev Med 2015 50 (1) 30-39 INTRODUCTION: Excessive sodium intake is a key modifiable risk factor for hypertension and cardiovascular disease. Although 95% of U.S. adults exceed intake recommendations, knowledge is limited regarding whether doctor or health professional advice motivates patients to reduce intake. Our objectives were to describe the prevalence and determinants of taking action to reduce sodium, and to test whether receiving advice was associated with action. METHODS: Analyses, conducted in 2014, used data from the 2013 Behavioral Risk Factor Surveillance System, a state-based telephone survey representative of non-institutionalized adults. Respondents (n=173,778) from 26 states, the District of Columbia, and Puerto Rico used the new optional sodium module. We estimated prevalence ratios (PRs) based on average marginal predictions, accounting for the complex survey design. RESULTS: Fifty-three percent of adults reported taking action to reduce sodium intake. Prevalence of action was highest among adults who received advice (83%), followed by adults taking antihypertensive medications, adults with diabetes, adults with kidney disease, or adults with a history of cardiovascular disease (range, 73%-75%), and lowest among adults aged 18-24 years (29%). Overall, 23% of adults reported receiving advice to reduce sodium intake. Receiving advice was associated with taking action (prevalence ratio=1.59; 95% CI=1.56, 1.61), independent of sociodemographic and health characteristics, although some disparities were observed across race/ethnicity and BMI categories. CONCLUSIONS: Our results suggest that more than half of U.S. adults in 26 states and two territories are taking action to reduce sodium intake, and doctor or health professional advice is strongly associated with action. |
Effects of total-body digital photography on cancer worry in patients with atypical mole syndrome.
Moye MS , King SM , Rice ZP , DeLong LK , Seidler AM , Veledar E , Curiel-Lewandrowski C , Chen SC . JAMA Dermatol 2014 151 (2) 137-43 IMPORTANCE: Cancer worry about developing melanoma in at-risk patients may affect one's quality of life and adherence to screening. Little is known about melanoma-related worry in patients with atypical mole syndrome (AMS). OBJECTIVES: To quantify levels and elucidate predictors of worry related to developing melanoma in patients with AMS and to determine whether total-body digital photography (TBDP) in pigmented lesion clinics (PLCs) reduces worry. DESIGN, SETTING, AND PARTICIPANTS: In this pretest-posttest study, patients with AMS from PLCs at 2 academic medical centers were recruited from June 1, 2005, through October 31, 2008, to answer questions about cancer worry before and after undergoing TBDP. Questionnaires used included the new melanoma and recurrent melanoma Revised Impact of Event Scale (RIES), the Melanoma Worry Scale (MWS), the Hospital Anxiety and Depression Scale, and the Life Orientation Test. INTERVENTIONS: All patients underwent TBDP. Main Outcomes and Measures: Changes in the MWS and new melanoma RIES scores. RESULTS: A total of 138 patients completed baseline questionnaires; 108 patients (78.3%) completed questionnaires after TBDP. Baseline levels of worry were low and reduced further after TBDP. In patients with a personal history of melanoma, worry was reduced on all scales. In patients without a personal history of melanoma, only the new melanoma RIES score was significantly decreased. Predictors of baseline MWS scores include female sex, personal history of melanoma, and higher Hospital Anxiety and Depression Scale scores, adjusted for demographics, family history of melanoma, and Life Orientation Test scores. Adjusted predictors of the baseline new melanoma RIES score were similar but also included lower educational level and did not include sex. CONCLUSIONS AND RELEVANCE: Patients with AMS have low levels of melanoma-related worry, which is similar to data from other populations at high risk of cancers. We found that TBDP is a clinically useful tool that can be used in PLCs to help decrease worry about developing melanoma in at-risk patients. |
An effective approach to high blood pressure control: a science advisory from the American Heart Association, the American College of Cardiology, and the Centers for Disease Control and Prevention
Go AS , Bauman MA , Coleman King SM , Fonarow GC , Lawrence W , Williams KA , Sanchez E . Hypertension 2014 63 (4) 878-85 Cardiovascular diseases, including heart disease, hypertension and heart failure, along with stroke, continue to be leading causes of death in the United States.1,2 Hypertension currently affects nearly 78 million* adults in the United States and is also a major modifiable risk factor for other cardiovascular diseases and stroke.1 According to data from the National Health and Nutrition Evaluation Survey (NHANES) in 2007–2010, 81.5% of those with hypertension are aware they have it, and 74.9% are being treated but only 52.5% are under control, with significant variation across different patient subgroups.1,3–6 Of those with uncontrolled hypertension, 89.4% reported having a usual source of health care, and 85.2% reported having health insurance.7 This is the current status, despite the fact that therapies to lower blood pressure and associated risks of cardiovascular events and death have been available for decades and various education and quality improvement efforts have been targeted at patients and healthcare providers. | The direct and indirect costs of hypertension are enormous, considering the number of patients and their families impacted as well as the healthcare dollars spent on treatment and blood pressure-related complications.8 Currently, hypertension affects 46% of patients with known cardiovascular disease, 72% of those who have suffered a stroke, and was listed as a primary or contributing cause in approximately 15% of the 2.4 million deaths in 2009.1 In 2008, the total estimated direct and indirect cost of hypertension was estimated at $69.9 billion.8 Thus, it is imperative to identify, disseminate and implement more effective approaches to achieve optimal control of this condition. |
Kidney cancer incidence and mortality among American Indians and Alaska Natives in the United States, 1990-2009
Li J , Weir HK , Jim MA , King SM , Wilson R , Master VA . Am J Public Health 2014 104 Suppl 3 S396-403 OBJECTIVES: We describe rates and trends in kidney cancer incidence and mortality and identify disparities between American Indian/Alaska Native (AI/AN) and White populations. METHODS: To improve identification of AI/AN race, incidence and mortality data were linked with Indian Health Service (IHS) patient records. Analysis focused on residents of IHS Contract Health Service Delivery Area counties; Hispanics were excluded. We calculated age-adjusted kidney cancer incidence (2001-2009) and death rates (1990-2009) by sex, age, and IHS region. RESULTS: AI/AN persons have a 1.6 times higher kidney cancer incidence and a 1.9 times higher kidney cancer death rate than Whites. Despite a significant decline in kidney cancer death rates for Whites (annual percentage change [APC] = -0.3; 95% confidence interval [CI] = -0.5, 0.0), death rates for AI/AN persons remained stable (APC = 0.4; 95% CI = -0.7, 1.5). Kidney cancer incidence rates rose more rapidly for AI/AN persons (APC = 3.5; 95% CI = 1.2, 5.8) than for Whites (APC = 2.1; 95% CI = 1.4, 2.8). CONCLUSIONS: AI/AN individuals have greater risk of developing and dying of kidney cancers. Incidence rates have increased faster in AI/AN populations than in Whites. Death rates have decreased slightly in Whites but remained stable in AI/AN populations. Racial disparities in kidney cancer are widening. |
Protocol-based treatment of hypertension: a critical step on the pathway to progress
Frieden TR , King SM , Wright JS . JAMA 2013 311 (1) 21-2 Improved treatment of hypertension is among the most important—and quite possibly also the single most neglected—area of clinical medicine. Only half of Americans with hypertension have blood pressure less than 140/90 mm Hg, and more than 13%—an estimated 9 million people—have a systolic blood pressure of 160 mm Hg or higher and/or diastolic pressure of 100 mm Hg or higher.1 Much better control is possible: Canada has a rate of blood pressure control of more than 65%,2 and the Minneapolis-St Paul region has a level of blood pressure control more than 20 percentage points higher than the United States as a whole.3 The United States is making progress, but this progress is painfully slow—the rate of control is increasing only 1% per year.4 | In simple numbers, it is estimated that nearly 36 million US adults have uncontrolled blood pressure, with 2 major subgroups that would benefit from protocol-based care.1 The first is the large number of people—14 million—who are unaware of their hypertension.1 Most of these people are hiding in plain sight: they are in clinical treatment with elevated blood pressure documented, but hypertension neither diagnosed nor treated. High-performing systems can reduce by half the proportion of hypertensive patients unaware of their blood pressure and not being treated.5 The second group is the estimated 16 million people who know they have hypertension and are taking medication for it, but do not yet have it under control.1 |
