Introduction: Variants of the APOL1 gene are associated with chronic kidney disease (CKD) in people of African ancestry, although evidence for their impact in people with HIV are sparse. Methods: We conducted a cross-sectional study investigating the association between APOL1 renal risk alleles and kidney disease in people of African ancestry with HIV in the UK. The primary outcome was end-stage kidney disease (ESKD; estimated glomerular filtration rate [eGFR] of 2, chronic dialysis, or having received a kidney transplant). The secondary outcomes included renal impairment (eGFR 2), albuminuria (albumin-to-creatinine ratio [ACR] >30 mg/mmol), and biopsy-proven HIV-associated nephropathy (HIVAN). Multivariable logistic regression was used to estimate the associations between APOL1 high-risk genotypes (G1/G1, G1/G2, G2/G2) and kidney disease outcomes. Results: A total of 2864 participants (mean age 48.1 [SD 10.3], 57.3% female) were genotyped, of whom, 354 (12.4%) had APOL1 high-risk genotypes, and 99 (3.5%) had ESKD. After adjusting for demographic, HIV, and renal risk factors, individuals with APOL1 high-risk genotypes were at increased odds of ESKD (odds ratio [OR] 10.58, 95% CI 6.22–17.99), renal impairment (OR 5.50, 95% CI 3.81–7.95), albuminuria (OR 3.34, 95% CI 2.00–5.56), and HIVAN (OR 30.16, 95% CI 12.48–72.88). An estimated 49% of ESKD was attributable to APOL1 high-risk genotypes. Conclusion: APOL1 high-risk genotypes were strongly associated with kidney disease in people of African ancestry with HIV and accounted for approximately half of ESKD cases in this cohort.

BACKGROUND Blood pressure (BP) measured in the office setting increases from early through later adulthood. However, it is unknown to what extent out-of-office BP derived via ambulatory BP monitoring (ABPM) increases over time, and which participant characteristics and risk factors might contribute to these increases. METHODS We assessed 25-year change in office- and ABPM-derived BP across sex, race, diabetes mellitus (DM), and body mass index (BMI) subgroups in the Coronary Artery Risk Development in Young Adults study using multivariable-adjusted linear mixed effects models. RESULTS We included 288 participants who underwent ABPM at the Year 5 Exam (mean [SD] age, 25.1 [3.7]; 45.8% men) and 455 participants who underwent ABPM at the Year 30 Exam (mean [SD] age, 49.5 [3.7]; 42.0% men). Office, daytime, and nighttime systolic BP (SBP) increased 12.8 (95% confidence interval [CI], 7.6–17.9), 14.7 (95% CI, 9.7–19.8), and 16.6 (95% CI, 11.4–21.8) mm Hg, respectively, over 25 years. Office SBP increased 6.5 (95% CI, 2.3–10.6) mm Hg more among black compared with white participants. Daytime SBP increased 6.3 (95% CI, 0.2–12.4) mm Hg more among participants with a BMI ≥25 vs. CONCLUSIONS Office- and ABPM-derived BP increased more from early through middle adulthood among black adults and participants with DM and BMI ≥25 kg/m2.

Resistant hypertension, defined as blood pressure levels above goal while taking ≥3 classes of antihypertensive medication or ≥4 classes regardless of blood pressure level, is associated with increased cardiovascular disease risk. The 2018 American Heart Association Scientific Statement on Resistant Hypertension recommends healthy lifestyle habits and thiazide-like diuretics and mineralocorticoid receptor antagonists for adults with resistant hypertension. The term apparent treatment-resistant hypertension (aTRH) is used when pseudoresistance cannot be excluded. We estimated the use of healthy lifestyle factors and recommended antihypertensive medication classes among US Black adults with aTRH. Data were pooled for Black participants in the JHS (Jackson Heart Study) in 2009 to 2013 (n=2496) and the REGARDS study (Reasons for Geographic and Racial Differences in Stroke) in 2013 to 2016 (n=3786). Outcomes included lifestyle factors (not smoking, not consuming alcohol, ≥75 minutes of vigorous-intensity or ≥150 minutes of moderate or vigorous physical activity per week, and body mass index 2 ) and recommended antihypertensive medications (thiazide-like diuretics and mineralocorticoid receptor antagonists). Overall, 28.3% of participants who reported taking antihypertensive medication had aTRH. Among participants with aTRH, 14.5% and 1.2% had ideal levels of 3 and 4 of the lifestyle factors, respectively. Also, 5.9% of participants with aTRH reported taking a thiazide-like diuretic, and 9.8% reported taking a mineralocorticoid receptor antagonist. In conclusion, evidence-based lifestyle factors and recommended pharmacological treatment are underutilized in Black adults with aTRH. Increased use of lifestyle recommendations and antihypertensive medication classes specifically recommended for aTRH may improve blood pressure control and reduce cardiovascular disease–related morbidity and mortality among US Black adults.

BACKGROUND Obstructive sleep apnea (OSA), nocturnal hypertension, and nondipping systolic blood pressure (BP) are each highly prevalent among African Americans. However, few data are available on the association between OSA and nighttime BP in this population. METHODS We examined the association of OSA with nighttime BP among African Americans who completed 24-hour ambulatory BP monitoring (ABPM) at Exam 1 (2000–2004) of the Jackson Heart Study (JHS) and subsequently participated in the JHS Sleep Study (2012–2016). Type 3 home sleep apnea testing was used to assess OSA measures, including respiratory event index (REI4%) and percent sleep time RESULTS Among 206 participants who completed ABPM and participated in the Jackson Heart Sleep Study, 50.5% had nocturnal hypertension and 26.2% had moderate to severe OSA (REI4% ≥15 events/hour). After multivariable adjustment, each SD (13.3 events/hour) increase in REI4% was associated with 1.75 mm Hg higher nighttime DBP (95% confidence interval (CI): 0.38, 3.11) and a prevalence ratio of 1.11 (95% CI: 1.00, 1.24) for nocturnal hypertension. Each SD (10.4%) increase in nocturnal hypoxemia was associated with a 1.91 mm Hg higher nighttime SBP (95% CI: 0.15, 3.66). CONCLUSIONS Severity of OSA and nocturnal hypoxemia were associated with high nighttime BP in African American participants in the JHS.

OBJECTIVES: To evaluate the associations of high awake blood pressure (BP), high asleep BP, and non-dipping BP, determined by ambulatory BP monitoring (ABPM), with left ventricular (LV) hypertrophy (LVH) and geometry. METHODS: Black and white participants (n=687) in the Coronary Artery Risk Development in Young Adults (CARDIA) study underwent 24-hour ABPM and echocardiography at the Year 30 Exam in 2015–2016. The prevalence and prevalence ratios (PR) of LVH were calculated for high awake systolic BP (≥ 130 mmHg), high asleep systolic BP (≥ 110 mmHg), the cross-classification of high awake and asleep systolic BP, and non-dipping systolic BP (percentage decline in awake-to-asleep systolic BP < 10%). Odds ratios (ORs) for abnormal LV geometry associated with these phenotypes were calculated. RESULTS: Overall, 46.0% and 49.1% of study participants had high awake and asleep systolic BP, respectively, and 31.1% had non-dipping systolic BP. After adjustment for demographics and clinical characteristics, high awake systolic BP was associated with a PR for LVH of 2.79, (95% confidence interval [95% CI] 1.63–4.79). High asleep systolic BP was also associated with a PR for LVH of 2.19 (95% CI 1.25–3.83). There was no evidence of an association between non-dipping systolic BP and LVH (PR 0.70, 95% CI 0.44–1.12). High awake systolic BP with or without high asleep systolic BP was associated with a higher OR of concentric remodeling and hypertrophy. CONCLUSION: Awake and asleep systolic BP, but not the decline in awake-to-asleep systolic BP, were associated with increased prevalence of cardiac end-organ damage.

Purpose Circular frames have been the gold standard of treatment for complex deformity corrections and bone loss. However, despite the success of frames, patient satisfaction has been low, and complications are frequent. Most recently, lengthening nails have been used to correct leg length discrepancies. In this article, we review the current trends in deformity correction with emphasis on bone lengthening and present our case examples on the use of lengthening nails for management of complex malunions, non-unions, and a novel use in bone transport. Materials and methods A nonsystematic literature review on the topic was performed. Four case examples from our institute, Brighton and Sussex University Hospitals, East Sussex, England, UK, were included. Results New techniques based on intramedullary bone lengthening and deformity correction are replacing the conventional external frames. Introduction of lengthening and then nailing and lengthening over a nail techniques paved the way for popularization of the more recent lengthening nails. Lengthening nails have gone through evolution from the first mechanical nails to motorized nails and more recently the magnetic lengthening nails. Two case examples demonstrate successful use of lengthening nails for management of malunion, and two case examples describe novel use in management of non-unions, including the first report in the literature of plate-assisted bone segment transport for the longest defect successfully treated using this novel technique. Conclusion With the significant advancement of intramedullary lengthening devices with lower complications rates and higher patient satisfaction, the era of the circular frame may be over.

OBJECTIVE: Nocturnal hypertension and non-dipping systolic blood pressure (SBP) are associated with increased cardiovascular disease (CVD) risk. Short and long sleep duration (SSD and LSD) are also associated with increased CVD risk and may be risk factors for nocturnal hypertension and non-dipping SBP. We examined the association between SSD and LSD with sleep BP, nocturnal hypertension, and non-dipping SBP among 647 white and African American Coronary Artery Risk Development in Young Adults (CARDIA) study participants who completed 24-hour ambulatory BP monitoring, wrist actigraphy, and sleep diaries in 2015-2016. METHODS: The times when participants were asleep and awake were determined from actigraphy complemented by sleep diaries. Nocturnal hypertension was defined as sleep BP ≥120/70 mmHg and non-dipping SBP as mean sleep-to-awake SBP ratio >0.90. Sleep duration was categorized as SSD (

Sickle cell trait (SCT) has been associated with chronic kidney disease (CKD) in African Americans, although evidence for its impact in Africans and people with HIV is currently lacking. We conducted a cross-sectional study investigating the association between SCT and kidney disease in people of African ancestry with HIV in the UK.The primary outcome was estimated glomerular filtration rate (eGFR) 60 ml/min per 1.73 mA total of 2895 participants (mean age 48.1 [SD 10.3], 57.2% female) were included, of whom 335 (11.6%) had SCT and 352 (12.2%) had eGFR 60 ml/min per 1.73 mOur results extend previously reported associations between SCT and kidney disease to people with HIV. In people of African ancestry with HIV, these associations were largely restricted to those with

OBJECTIVE Recent studies have suggested that prediabetes is associated with an increased risk for cardiovascular disease (CVD) only among individuals with concomitant hypertension. RESEARCH DESIGN AND METHODS We analyzed the association between prediabetes and CVD by hypertension status among 3,313 black adults in the Jackson Heart Study (JHS) without diabetes or a history of CVD at baseline (2000–2004). Prediabetes was defined as fasting plasma glucose between 100 and 125 mg/dL or hemoglobin A1c between 5.7 and 6.4% (39 and 46 mmol/mol). Hypertension was defined as systolic/diastolic blood pressure ≥140/90 mmHg and/or self-reported antihypertensive medication use. Participants were followed for incident CVD events and all-cause mortality through 31 December 2014. RESULTS Overall, 35% of JHS participants did not have prediabetes or hypertension, 18% had prediabetes alone, 22% had hypertension alone, and 25% had both prediabetes and hypertension. Compared with participants without either condition, the multivariable-adjusted hazard ratios for CVD events among participants with prediabetes alone, hypertension alone, and both prediabetes and hypertension were 0.86 (95% CI 0.51, 1.45), 2.09 (1.39, 3.14), and 1.93 (1.28, 2.90), respectively. Among participants with and without hypertension, there was no association between prediabetes and an increased risk for CVD (0.78 [0.46, 1.34] and 0.94 [0.70, 1.26], respectively). No association was present between prediabetes and all-cause mortality among participants with or without hypertension. CONCLUSIONS Regardless of hypertension status, prediabetes was not associated with an increased risk for CVD or all-cause mortality in this cohort of black adults.

The 2017 Hypertension Clinical Practice Guidelines recommend out-of-clinic BP monitoring to screen for white coat and masked hypertension among adults not taking antihypertensive medication and white coat effect and masked uncontrolled hypertension among adults taking antihypertensive medication. We estimated the percentage of US adults meeting criteria for out-of-clinic BP monitoring by the American College of Cardiology/American Heart Association guideline using the 2011 to 2014 National Health and Nutrition Examination Survey (n=9623). Among US adults not taking antihypertensive medication, 92.6% (95% CI, 90.7%–94.1%) with systolic/diastolic BP ≥130/80 mm Hg met criteria for out-of-clinic BP monitoring to screen for white coat hypertension and 32.8% (95% CI, 30.4%–35.3%) with systolic/diastolic BP

When can a hyphen be described as ‘intrusive’? As with many other ‘rules’ of grammar and of punctuation, use of the hyphen is limited to a specific syntactical context. Hence, to use a hyphen where it should not be used makes it intrusive. Just like the apostrophe, it cannot be used arbitrarily. There is, for instance, a tattooist parlour in the English town of Oldham whose shopfront advertises Inkcredible Tatoo's (sic) and, with it, both the owner's or owners’ ability to play on words in writing and their inability to sign a plural form correctly – the rule being that apostrophes are not used to mark the plural of either common or proper nouns in written English.

In 2017, the American College of Cardiology/American Heart Association (ACC/AHA) and the American College of Physicians/American Academy of Family Physicians (ACP/AAFP) published blood pressure guidelines. Adults recommended antihypertensive medication initiation or intensification by the ACP/AAFP guideline receive the same recommendation from the ACC/AHA guideline. However, many adults ≥60 years old are recommended to initiate or intensify antihypertensive medication by the ACC/AHA but not the ACP/AAFP guideline. We compared atherosclerotic cardiovascular disease event rates according to antihypertensive treatment recommendations in the ACC/AHA and ACP/AAFP guidelines among adults ≥60 years old with systolic blood pressure ≥130 mm Hg or diastolic blood pressure ≥80 mm Hg in the REGARDS study (Reasons for Geographic and Racial Differences in Stroke) and the JHS (Jackson Heart Study). Among 4311 participants not taking antihypertensive medication at baseline, 11.4%, 61.2%, and 27.4% were recommended antihypertensive medication initiation by neither guideline, the ACC/AHA but not the ACP/AAFP guideline, and both guidelines, respectively. Atherosclerotic cardiovascular disease event rates (95% CI) for these groups were 3.4 (1.6–5.2), 18.0 (16.1–19.8), and 25.3 (21.9–28.6) per 1000 person-years, respectively. Among 7281 participants taking antihypertensive medication at baseline, 57.9% and 42.1% were recommended antihypertensive medication intensification by the ACC/AHA but not the ACP/AAFP guideline and both guidelines, respectively. Atherosclerotic cardiovascular disease event rates (95% CI) for these groups were 18.2 (16.7–19.7) and 33.0 (30.5–35.4) per 1000 person-years, respectively. In conclusion, adults recommended initiation or intensification of antihypertensive medication by the ACC/AHA but not the ACP/AAFP guideline have high atherosclerotic cardiovascular disease risk that may be reduced through treatment initiation or intensification.

Background: Over 10 years, achieving and maintaining 2017 ACC/AHA guideline goals could prevent 3.0 million (UR, 1.1–5.1 million), 0.5 million (UR, 0.2–0.7 million), and 1.4 million (UR, 0.6–2.0 million) cardiovascular disease (CVD) events compared with maintaining current blood pressure (BP) levels, achieving 2003 Seventh Joint National Committee Report goals, and achieving 2014 Eighth Joint National Committee goals, respectively. We estimated the number of cardiovascular disease events prevented and treatment-related serious adverse events incurred over 10 years among US adults with hypertension by achieving 2017 ACC/AHA guideline-recommended BP goals compared with (1) current BP levels, (2) achieving 2003 Seventh Joint National Committee Report BP goals, and (3) achieving 2014 Eighth Joint National Committee panel member report BP goals. Methods: US adults aged ≥45 years with an indication for BP treatment were grouped according to recommendations for antihypertensive drug therapy in the 2017 ACC/AHA guideline, 2003 Seventh Joint National Committee Report, and 2014 Eighth Joint National Committee. Population sizes were estimated from the 2011 to 2014 National Health and Nutrition Examination Surveys. Rates for fatal and nonfatal CVD events (stroke, coronary heart disease, or heart failure) were estimated from the REGARDS (REasons for Geographic And Racial Differences in Stroke) study, weighted to the US population. CVD risk reductions with treatment to BP goals and risk for serious adverse events were obtained from meta-analyses of BP-lowering trials. CVD events prevented and treatment-related nonfatal serious adverse events over 10 years were calculated. Uncertainty surrounding main data inputs was expressed in uncertainty ranges (UR). Results: Over ten years, achieving and maintaining 2017 ACC/AHA guideline goals compared with current BP levels, achieving 2003 Seventh Joint National Committee Report goals, or achieving 2014 Eighth Joint National Committee goals could prevent 3.0 million (UR, 1.1–5.1 million), 0.5 million (UR, 0.2–0.7 million), or 1.4 million (UR, 0.6–2.0 million) CVD events, respectively. Compared with current BP levels, achieving and maintaining 2017 goals could prevent 71.9 (UR, 26.6–122.3) CVD events per 1000 treated. Achieving 2017 guideline BP goals compared with current BP levels could also lead to nearly 3.3 million more serious adverse events over 10 years (UR, 2.2–4.4 million). Conclusions: Achieving and maintaining 2017 ACC/AHA BP goals could prevent a greater number of CVD events than achieving 2003 Seventh Joint National Committee Report or 2014 Eighth Joint National Committee BP goals but could also lead to more serious adverse events.

Background The American Heart Association created the Life’s Simple 7 (LS7) metrics to promote cardiovascular health (CVH) by achieving optimal levels of blood pressure, cholesterol, blood sugar, physical activity, diet, weight, and smoking status. The degree to which psychosocial factors such as stress and depression impact one’s ability to achieve optimal CVH is unclear, particularly among hypertensive African Americans. Methods Cross-sectional analyses included 1,819 African Americans with hypertension participating in the Jackson Heart Study (2000–2004). Outcomes were LS7 composite and individual component scores (defined as poor, intermediate, ideal). High perceived chronic stress was defined as the top quartile of Weekly Stress Inventory scores. High depressive symptoms were defined as Center for Epidemiologic Studies Depression scale scores of ≥16. We compared 4 groups: high stress alone; high depressive symptoms alone; high stress and high depressive symptoms; low stress and low depressive symptoms (reference) using linear regression for total LS7 scores and logistic regression for LS7 components. Results Participants with both high stress and depressive symptoms had lower composite LS7 scores (B [95% confidence interval] = −0.34 [−0.65 to −0.02]) than those with low stress and depressive symptoms in unadjusted and age/sex-adjusted models. They also had poorer health status for smoking (odds ratio [95% confidence interval] = 0.52 [0.35–0.78]) and physical activity (odds ratio [95% confidence interval] = 0.71 [0.52–0.95]) after full covariate adjustment. Conclusions The combination of high stress and high depressive symptoms was associated with poorer LS7 metrics in hypertensive African Americans. Psychosocial interventions may increase the likelihood of engaging in behaviors that promote optimal CVH.

An isolated Spanish frontier settlement with little or no significant mineral wealth, exportable crops, or exploitable indigenous population, colonial Costa Rica had only a rudimentary military. After independence in 1825, the population expanded and diversified as coffee cultivation generated growing wealth. Competing factions of the emergent coffee bourgeoisie fought to control the emerging state using elite-linked military officers to seize ruling power. Modernization and an external threat from Nicaragua and U.S. freebooters at mid-19th century led nation-building leaders to invest heavily in the army. Victorious in the 1856–1857 National War in Nicaragua, the military attained maximum size and power from 1870 to 1920 while oligarchic factions disputed ruling authority via fraudulent elections and coups d’état. Integration into the world economy deepened with banana production after 1890. Subsequent recessions and wars generated domestic economic inequality and a growing labor movement demanding reform. Civilian rule in the early 20th century was interrupted by the military regime of Federico Tinoco (1917–1919), whose atrocities led his civilian successors to almost dismantle the army. When a civil war erupted in 1948 against the divided, Communist-allied reformist government of the 1940s, the rebels defeated the army. The victorious National Liberation junta and new constitution abolished the army in 1949. Costa Rica committed to a police-based security model, nonaggression toward neighbors, and reliance on international alliances. Meanwhile, elites, spared the menace of military disruption, developed a successful electoral democratic regime. This has contributed to seven decades of political stability and allowed Costa Rica to invest successfully in economic development and its citizens’ welfare.

The addition of multiple “mini-trackers” (MTs) to the Southern African Large Telescope (SALT) would create in effect several four-to-six-meter class telescopes that take advantage of the SALT 10-meter diameter primary mirror’s 35 degree diameter uncorrected field-of-view. These devices, with a 100 square degree patrol area, would provide valuable follow up capability for the large astronomical surveys either in operation (e.g. MeerKAT, eROSITA, Gaia), or expected to begin operations soon (e.g. LSST, SKA, Euclid). A feasibility study was conducted to evaluate the technical practicality associated with the design, fabrication, integration, and testing of a prototype MT for SALT. The study determined that the development of a mini-tracker was indeed feasible, and work has begun on the concept design phase of the project.

Background: Social determinants of health (SDH) are individually associated with incident coronary heart disease (CHD) events. Indices reflecting social deprivation have been developed for population management, but are difficult to operationalize during clinical care. We examined whether a simple count of SDH is associated with fatal incident CHD and nonfatal myocardial infarction (MI). Methods: We used data from the prospective longitudinal REGARDS cohort study (Reasons for Geographic and Racial Differences in Stroke), a national population-based sample of community-dwelling Black and White adults age ≥45 years recruited from 2003 to 2007. Seven SDH from the 5 Healthy People 2020 domains included social context (Black race, social isolation); education (educational attainment); economic stability (annual household income); neighborhood (living in a zip code with high poverty); and health care (lacking health insurance, living in 1 of the 9 US states with the least public health infrastructure). Outcomes were expert adjudicated fatal incident CHD and nonfatal MI. Results: Of 22 152 participants free of CHD at baseline, 58.8% were women and 42.0% were Black; 20.6% had no SDH, 30.6% had 1, 23.0% had 2, and 25.8% had ≥3. There were 463 fatal incident CHD events and 932 nonfatal MIs over a median of 10.7 years (interquartile range, 6.6 to 12.7). Fewer SDHs were associated with nonfatal MI than with fatal incident CHD. The age-adjusted incidence per 1000 person-years increased with the number of SDH for both fatal incident CHD (0 SDH, 1.30; 1 SDH, 1.44; 2 SDH, 2.05; ≥3 SDH, 2.86) and nonfatal MI (0 SDH, 3.91; 1 SDH, 4.33; ≥2 SDH, 5.44). Compared with those without SDH, crude and fully adjusted hazard ratios for fatal incident CHD among those with ≥3 SDH were 3.00 (95% CI, 2.17 to 4.15) and 1.67 (95% CI, 1.18 to 2.37), respectively; hazard ratios for nonfatal MI among those with ≥2 SDH were 1.57 (95% CI, 1.30 to 1.90) and 1.14 (95% CI, 0.93 to 1.41), respectively. Conclusions: A greater burden of SDH was associated with a graded increase in risk of incident CHD, with greater magnitude and independent associations for fatal incident CHD. Counting the number of SDHs may be a promising approach that could be incorporated into clinical care to identify individuals at high risk of CHD.

Importance High blood pressure (BP) during sleep (asleep blood pressure) is associated with an increased risk of cardiovascular disease, but a national prevalence estimate of masked asleep hypertension (high BP while sleeping but without high BP measured in the clinic [clinic BP]) for the United States is lacking. Objectives To estimate the prevalence of masked asleep hypertension among US adults by using BP thresholds from the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC7) and the 2017 American College of Cardiology-American Heart Association (ACC-AHA) BP guidelines. Design, setting, and participants This cohort analysis pooled data from 3000 participants in 4 US population-based studies that conducted 24-hour ambulatory BP monitoring (ABPM) and 17 969 participants in the 2011-2016 National Health and Nutrition Examination Survey (NHANES) without ABPM. Masked asleep hypertension status in NHANES was imputed using a 2-stage multiple imputation process. Data were collected from 2000 to 2016 and analyzed from March 4, 2019, to June 29, 2020. Main outcomes and measures High clinic BP was defined as clinic systolic BP (SBP)/diastolic BP (DBP) of at least 140/90 mm Hg using JNC7 and at least 130/80 mm Hg using 2017 ACC-AHA guidelines. High asleep BP was defined as mean asleep SBP/DBP of at least 120/70 mm Hg for JNC7 and at least 110/65 mm Hg for the 2017 ACC-AHA guidelines. Masked asleep hypertension was defined as high asleep BP without high clinic BP. Results For the 3000 pooled cohort participants, the mean (SD) age was 52.0 (12.0) years, and 62.6% were women. For the 17 969 NHANES participants, the mean (SD) age was 46.7 (17.5) years, and 51.8% (weighted) were women. The estimated prevalence of masked asleep hypertension among US adults was 18.8% (95% CI, 16.7%-20.8%; 44.4 million US adults) using the JNC7 guideline and 22.7% (95% CI, 20.6%-24.8%; 53.7 million US adults) using the 2017 ACC-AHA guideline criteria. The prevalence of masked asleep hypertension was higher among older adults (aged ≥65 years, 24.4% [95% CI, 20.7%-28.0%]), men (27.0% [95% CI, 24.1%-29.9%]), non-Hispanic Black individuals (28.7% [95% CI, 25.4%-32.0%]), those who were taking antihypertensives (24.4% [95% CI, 21.1%-27.8%]), those who had masked daytime hypertension (44.7% [95% CI, 40.1%-49.3%]), and those with diabetes (27.6% [95% CI, 23.5%-31.8%]), obesity (24.3% [95% CI, 21.8%-26.9%]), or chronic kidney disease (21.5% [95% CI, 17.3%-25.6%]) using the 2017 ACC-AHA guideline. An estimated 11.9% of US adults (28.2 million) had isolated masked asleep hypertension (masked asleep hypertension but without high awake BP) using JNC7 guideline criteria, as did an estimated 13.3% (31.5 million) using 2017 ACC-AHA guideline criteria. Conclusions and relevance These findings suggest that the prevalence of masked asleep hypertension is high among US adults. Data are needed on the cardiovascular risk reduction benefits of treating asleep hypertension.

Background The Life’s Simple 7 (LS7) metric incorporates health behaviors (body mass index, diet, smoking, physical activity) and health factors (blood pressure, cholesterol, glucose) to estimate an individual’s level of cardiovascular health. The association between cardiovascular health and incident hypertension is unresolved. Hypertension’s threshold was recently lowered and it is unclear if better cardiovascular health is associated with lower risk of incident hypertension with the updated threshold or in a multirace cohort. We sought to assess the association between better LS7 score and risk of incident hypertension among Black and White adults using a 130/80 mm Hg hypertension threshold. Methods and Results We determined the association between LS7 metric and incident hypertension in the REGARDS (Reasons for Geographic and Racial Disparities in Stroke) study, including participants free of baseline hypertension (2003–2007) who completed a second visit between 2013 and 2016. Hypertension was defined as systolic/diastolic blood pressure ≥130/80 mm Hg or antihypertensive medication use. Each LS7 component was assigned 0 (poor), 1 (intermediate), or 2 (ideal) points. We generated a 14‐point score by summing points. Among 2930 normotensive participants (20% Black, 80% White), the median (25th–75th percentiles) LS7 total score was 9 (8–10) points. Over a median follow‐up of 9 years, 42% developed hypertension. In the fully adjusted model, each 1‐point higher LS7 score had a 6% lower risk of incident hypertension (risk ratio, 0.94 per 1 point; 95% CI, 0.92–0.96). Conclusions Better cardiovascular health was associated with lower risk of incident hypertension using a 130/80 mm Hg hypertension threshold among Black and White adults.

BACKGROUND Several atherosclerotic cardiovascular disease (ASCVD) risk factors are associated with awake and nocturnal hypertension. METHODS We assessed the association between a composite ASCVD risk score and awake or nocturnal hypertension using data from participants aged 40–79 years who completed ambulatory blood pressure monitoring at the Year 30 Coronary Artery Risk Development in Young Adults study exam in 2015–2016 (n = 716) and the baseline Jackson Heart Study exam in 2000–2004 (n = 770). Ten-year predicted ASCVD risk was calculated using the Pooled Cohort risk equations. Awake hypertension was defined as mean awake systolic blood pressure (SBP) ≥135 mm Hg or diastolic blood pressure (DBP) ≥85 mm Hg and nocturnal hypertension was defined as mean asleep SBP ≥120 mm Hg or DBP ≥70 mm Hg. RESULTS Among participants with a 10-year predicted ASCVD risk CONCLUSIONS Using 10-year predicted ASCVD risk in conjunction with clinic BP improves discrimination between individuals with and without awake or nocturnal hypertension.

Background Among US Hispanics/Latinos, the largest ethnic minority population in the United States, hypertension incidence has not been thoroughly reported. The goal of this study was to describe the incidence of hypertension among US Hispanic/Latino men and women of diverse Hispanic/Latino background. Methods and Results We studied 6171 participants of the Hispanic Community Health Study/Study of Latinos, a diverse group of self‐identified Hispanics/Latinos from 4 US urban communities, aged 18 to 74 years, and free from hypertension in 2008 to 2011 and re‐examined in 2014 to 2017. Hypertension was defined as self‐reported use of anti‐hypertension medication, or measured systolic blood pressure ≥130 mm Hg, or diastolic blood pressure ≥80 mm Hg. Results were weighted given the complex survey design to reflect the target population. Among men, the 6‐year age‐adjusted probability of developing hypertension was 21.7% (95% CI , 19.5–24.1) and differed by Hispanic/Latino background. Specifically, the probability was significantly higher among men of Cuban (27.1%; 95% CI , 20.2–35.2) and Dominican (28.1%; 95% CI , 19.5–38.8) backgrounds compared with Mexican Americans (17.6%; 95% CI : 14.5–21.2). Among women, the 6‐year age‐adjusted probability of developing hypertension was 19.7% (95% CI , 18.1–21.5) and also differed by Hispanic/Latino background. Specifically, the probability was significantly higher among women of Cuban (22.6%; 95% CI , 18.3–27.5), Dominican (23.3%; 95% CI , 18.0–29.5), and Puerto Rican (28.2%; 95% CI , 22.7–34.4) backgrounds compared with Mexican Americans (16.0%; 95% CI , 13.9–18.4). Conclusions Hypertension incidence varies by Hispanic/Latino background, with highest incidence among those of Caribbean background.

BACKGROUND: Suboptimal sleep, including insufficient/long sleep duration and poor sleep quality, is a risk factor for cardiovascular disease (CVD) common but there is little information among African Americans, a group with a disproportionate CVD burden. The current study examined the association between suboptimal sleep and incident CVD among African Americans. METHODS: This study included 4,522 African Americans without CVD at baseline (2000–2004) of the Jackson Heart Study (JHS). Self-reported sleep duration was defined as very short (

Background Sleep characteristics and disorders are associated with higher blood pressure ( BP ) when measured in the clinic setting. Methods and Results We tested whether self‐reported sleep characteristics and likelihood of obstructive sleep apnea ( OSA ) were associated with nocturnal hypertension and nondipping systolic BP ( SBP ) among participants in the CARDIA (Coronary Artery Risk Development in Young Adults) study who completed 24‐hour ambulatory BP monitoring during the year 30 examination. Likelihood of OSA was determined using the STOP ‐Bang questionnaire. Global sleep quality, habitual sleep duration, sleep efficiency, and midsleep time were obtained from the Pittsburgh Sleep Quality Index. Nocturnal hypertension was defined as mean asleep SBP ≥120 mm Hg or diastolic BP ≥70 mm Hg. Nondipping SBP was defined as a decline in awake‐to‐asleep SBP SBP was 41.3% and 32.5%, respectively. After multivariable adjustment including cardiovascular risk factors, the prevalence ratios (PRs) for nocturnal hypertension and nondipping SBP associated with high versus low likelihood of OSA were 1.32 (95% CI, 1.00–1.75) and 1.31 (95% CI, 1.02–1.68), respectively. The association between likelihood of OSA and nocturnal hypertension was stronger for white participants (PR: 2.09; 95% CI, 1.23–3.48) compared with black participants (PR: 1.11; 95% CI, 0.79–1.56). The PR for nondipping SBP associated with a 1‐hour later midsleep time was 0.92 (95% CI, 0.85–0.99). Global sleep quality, habitual sleep duration, and sleep efficiency were not associated with either nocturnal hypertension or nondipping SBP . Conclusions These findings suggest that addressing OSA risk and sleep timing in a clinical trial may improve BP during sleep.

The cardiovascular disease (CVD) and mortality risk associated with morning blood pressure (BP) surge and its components among black adults, a population with high BP during the asleep period, is unknown. We studied Jackson Heart Study participants who completed 24-hour ambulatory BP monitoring at the baseline exam in 2000 to 2004 (n=761). The sleep-trough morning surge was calculated as the mean 2-hour postawakening systolic BP (SBP) minus the lowest nighttime SBP, preawakening morning surge as mean 2-hour postawakening SBP minus mean 2-hour preawakening SBP, and rising morning surge as the first postawakening SBP minus the last preawakening SBP. The primary outcome was the occurrence of CVD events including the composite of coronary heart disease or stroke. Over a median follow-up of 14.0 years, there were 74 CVD (coronary heart disease or stroke) events and 144 deaths. Higher tertiles of sleep-trough, preawakening, and rising SBP surge were not associated with CVD risk after multivariable adjustment. In contrast, the highest tertile of the individual components of morning surge, including postawakening SBP (tertiles 2 and 3 versus 1: hazard ratio [95% CI]: 1.58 [0.71–3.53] and 4.04 [1.91–8.52], respectively), lowest nighttime SBP (1.29 [0.59–2.84] and 2.87 [1.41–5.83]), preawakening SBP (1.26 [0.57–2.80] and 2.79 [1.32–5.93]), first postawakening SBP (1.60 [0.73–3.51] and 2.93 [1.40–6.16]), and last preawakening SBP (1.23 [0.57–2.68] and 2.99 [1.46–6.12]), was associated with increased CVD risk after multivariable adjustment. Among black adults, the components of morning SBP surge, but not morning SBP surge itself, were associated with increased CVD risk.
