Objective: The aim of the study was to determine if systolic blood pressure (SBP), total-tau (t-tau), and beta-amyloid (Aβ) in the cerebral spinal fluid (CSF) were associated with the results on the Consortium to Establish a Registry for Alzheimer’s Disease Word List (CERAD-WL) immediate and delayed recall, and the Mini Mental State Examination (MMSE) in “younger” older adults, controlling for age and sex.Method: We included 72 participants, mean age: 62.9 (SD 8.6, range 41–76) from a Norwegian memory clinic; eight were diagnosed with subjective cognitive decline, 32 with mild cognitive impairment (MCI), 30 with dementia of the Alzheimer’s type (DAT), and two with combined DAT and vascular dementia (VaD). Data were examined in three fitted multiple linear regression models using the CERAD-WL immediate and delayed recall, and MMSE as dependent variables; and SBP, t-tau, and Aβ as independent variables, controlling for age and sex.Results: The strongest associations were found in the model using CERAD-WL delayed recall as the dependent variable, where 45% of the variance was explained (standardized Beta = −0.313, p = 0.004 for t-tau and standardized Beta −0.238, p = 0.01 for SBP). The unique contribution of age was close to 8%, t-tau close to 7%, and SBP above 5%. When cardiovascular medication was entered into the analysis, the explained variance increased to 51% and Aβ became significant (standardized Beta = 0.216, p = 0.03). Participants on this medication exhibited worse performance on CERAD-WL delayed recall than those who were not on medication. Age (7%), t-tau (6%), and SBP (5%) showed the same unique contribution, whereas medication contributed 6% and Aβ contributed 4%. CERAD-WL immediate recall, and MMSE yielded similar findings, but explained variance was poorer for these two variables.Conclusions: Both elevated SBP and t-tau were associated with poorer cognitive performance, especially delayed recall. Those on cardiovascular medication were more impaired than were participants who were not on this medication—a finding that probably reflected cerebral incidents in the medicated group.

Abstract Hypertension (HT) is the largest contributor to cardiovascular disease mortality and is characterized by high prevalence and low awareness, treatment, and control rates in sub-Saharan Africa. May Measurement Month (MMM) is an international campaign intended to increase awareness of high blood pressure (BP) among the population and advocate for its importance to the health authorities. This study aimed to increase awareness of raised BP in a country where its nationwide prevalence is yet unestablished. Investigators trained and tested how to use the campaign materials, collected participants’ demographic data, lifestyle habits, and obtained from each one three BP measurements. Hypertension was defined as a BP ≥140/90 mmHg, or use of antihypertensive medication. Of the 18 719 screened (mean age 41 years; 61.4% men), 26.1% were found to be hypertensive of whom 46.3% were aware of their condition and 29.6% were taking antihypertensive medication. The control rate of HT was 43.0% in those on medication and 12.7% among all hypertensive respondents. Comorbidities found were—diabetes (3.3%), overweight/obesity (35.5%); and a previous stroke and a previous myocardial infarction were reported by 1.2% and 2.0%, respectively. Imputed age- and sex-standardized BP was higher in treated hypertensive individuals (135/85 mmHg) than those not treated (124/78 mmHg). Based on linear regression models adjusted for age and sex (and an interaction) and antihypertensive medication, stroke survivors, those who drank once or more per week (vs. never/rarely), and overweight/obese participants were associated with higher BP. MMM18 results in the Democratic Republic of the Congo corroborated the high prevalence of HT in Kinshasa screenees with low rates of treatment and control. Extension of the MMM campaign to other parts of the country is advisable.

AbstractThe bridging integrator 1 (BIN1) gene is the second most important susceptibility gene for late-onset Alzheimer’s disease (LOAD) after apolipoprotein E (APOE) gene. To explore whether the BIN1 methylation in peripheral blood changed in the early stage of LOAD, we included 814 participants (484 cognitively normal participants [CN] and 330 participants with subjective cognitive decline [SCD]) from the Chinese Alzheimer’s Biomarker and LifestylE (CABLE) database. Then we tested associations of methylation of BIN1 promoter in peripheral blood with the susceptibility for preclinical AD or early changes of cerebrospinal fluid (CSF) AD-related biomarkers. Results showed that SCD participants with significant AD biological characteristics had lower methylation levels of BIN1 promoter, even after correcting for covariates. Hypomethylation of BIN1 promoter were associated with decreased CSF Aβ42 (p = 0.0008), as well as increased p-tau/Aβ42 (p = 0.0001) and t-tau/Aβ42 (p < 0.0001) in total participants. Subgroup analysis showed that the above associations only remained in the SCD subgroup. In addition, hypomethylation of BIN1 promoter was also accompanied by increased CSF p-tau (p = 0.0028) and t-tau (p = 0.0130) in the SCD subgroup, which was independent of CSF Aβ42. Finally, above associations were still significant after correcting single nucleotide polymorphic sites (SNPs) and interaction of APOE ɛ4 status. Our study is the first to find a robust association between hypomethylation of BIN1 promoter in peripheral blood and preclinical AD. This provides new evidence for the involvement of BIN1 in AD, and may contribute to the discovery of new therapeutic targets for AD.

The Mean

Background: Cerebrovascular disease (CeVD) is an underlying cause of cognitive impairment and dementia. Hypertension is a known risk factor of CeVD, but the effects of mean of visit-to-visit blood pressure (BP) on incident CeVD and functional-cognitive decline remains unclear. Objective: To determine the association between mean of visit-to-visit BP with the incidence and progression of CeVD [white matter hyperintensities (WMH), infarcts (cortical infarcts and lacunes), cerebral microbleeds (CMBs), intracranial stenosis, and hippocampal volume] as well as functional-cognitive decline over 2 years of follow-up. Methods: 373 patients from a memory-clinic underwent BP measurements at baseline, year 1, and year 2. The mean of visit-to-visit systolic BP, diastolic BP, pulse pressure, and mean arterial pressure were calculated. Baseline and year 2 MRI scans were graded for WMH, infarcts, CMBs, intracranial stenosis, and hippocampal volume. Functional-cognitive decline was assessed using locally validated protocol. Logistic and linear regression models with odds ratios, mean difference, and 95%confidence interval were constructed to analyze associations of visit-to-visit BP on CeVD incidence and progression as well as functional-cognitive decline. Results: Higher mean of visit-to-visit diastolic BP was associated with WMH progression. Higher tertiles of diastolic BP was associated with WMH progression and incident CMBs. There was no association between mean of visit-to-visit BP measures with incident cerebral infarcts, intracranial stenosis, change in hippocampal volume, and functional-cognitive decline. Conclusion: These findings suggest the possibility of hypertension-related vascular brain damage. Careful monitoring and management of BP in elderly patients is essential to reduce the incidence and progression of CeVD.

Abstract This study examined the rate of secondary traumatic stress (STS) among social work students and the contribution of background variables, personal resources (mastery and self-differentiation) and environmental resources (supervision satisfaction and peer support) to STS. The sample consisted of 259 social work students at three social work schools in Israel. The findings indicated that the mean level of STS was mild. Of the students, 36 per cent suffered STS to a mild extent, 19 per cent to a moderate extent and 18 per cent reported a ‘high to extreme extent’. A significant contribution was made by the student’s year of study, students in their second year of social work school suffered more severely from STS than did students in their first or third years. A positive contribution was made by the student’s level of exposure and a unique contribution was made by mastery and supervision satisfaction to the explained variance of STS. The findings highlight the importance of raising awareness of STS and its implications for social work students, as well as the necessity of helping students cope with this phenomenon. In addition, the study emphasises the significant role of supervisors in the training agencies and the importance of increasing students’ sense of mastery.

Abstract Objectives: To investigate associations of egg intake with blood pressure (BP) and the role of dietary variables and other macro- and micro-nutrients in the association. Design: We used cross-sectional data for the USA as part of the INTERnational study on MAcro/micronutrients and blood Pressure (INTERMAP). INTERMAP was surveyed between 1996 and 1999, including four 24-h dietary recalls, two 24-h urine collections and eight measurements of systolic BP and diastolic BP (SBP, DBP). Average egg intake (g/d) was calculated. Multivariable linear regression models were used to estimate the association between egg intake (per each 50 g/d or per quintile) and BP. The roles of dietary variables and other macro- and micro-nutrients in this association were also investigated. Setting: In the USA. Participants: In total, 2195 US INTERMAP men and women aged 40–59 years. Results: Participants were 50 % female, 54 % non-Hispanic White and 16 % non-Hispanic Black. Mean egg intake (sd) in men and women was 30·4(29·8) and 21·6(20·5) g/d, respectively. Adjusting for demographics, socio-economics, lifestyle and urinary Na:K excretion ratios, we found non-linear associations with BP in non-obese women (P-quadratic terms: 0·004 for SBP and 0·035 for DBP).The associations remained after adjusting for dietary variables, macro/micro nutrients or minerals. Dietary cholesterol was highly correlated with egg intake and may factor in the association. No association was found in obese women and in obese or non-obese men. Conclusion: Egg intake was non-linearly associated with SBP and DBP in non-obese women, but not in obese women or men. Underlying mechanisms require additional study regarding the role of obesity and sex.

Abstract BACKGROUND Clinical evidence shows that diabetes may provoke uncontrolled blood pressure (BP) in hypertensive patients. However, racial differences in the associations of diabetes with uncontrolled BP outcomes among diagnosed hypertensive patients have not been evaluated. METHODS A total of 6,134 diagnosed hypertensive subjects aged ≥20 years were collected from the National Health and Nutrition Examination Survey 1999–2008 with a stratified multistage design. Odds ratios (ORs) and relative ORs of uncontrolled BP and effect differences in continuous BP for diabetes over race/ethnicity were derived using weighted logistic regression and linear regression models. RESULTS Compared with participants who did not have diabetes, non-Hispanic black participants with diabetes had a 138% higher chance of having uncontrolled BP, Mexican participants with diabetes had a 60% higher chance of having uncontrolled BP, and non-Hispanic white participants with diabetes had a 161% higher chances of having uncontrolled BP. The association of diabetes with uncontrolled BP was lower in Mexican Americans than in non-Hispanic blacks and whites (Mexican Americans vs. non-Hispanic blacks: relative OR = 0.55, 95% confidence interval (CI) = 0.37–0.82; Mexican Americans vs. non-Hispanic whites: relative OR = 0.53, 95% CI = 0.35–0.80) and the association of diabetes with isolated uncontrolled systolic BP was lower in Mexican Americans than in non-Hispanic whites (Mexican Americans vs. non-Hispanic whites: relative OR = 0.62, 95% CI = 0.40–0.96). Mexican Americans have a stronger associaton of diabetes with decreased systolic BP and diastolic BP than non-Hispanic whites, and a stronger association of diabetes with decreased diastolic BP than non-Hispanic blacks. CONCLUSIONS The association of diabetes with uncontrolled BP outcomes is lower despite higher prevalence of diabetes in Mexican Americans than in non-Hispanic whites. The stronger association of diabetes with BP outcomes in whites should be of clinical concern, considering they account for the majority of the hypertensive population in the United States.

<b><i>Background:</i></b> Orthostatic hypotension (OH) and impaired OH recovery derived from beat-to-beat blood pressure (BP) measurements are associated with detrimental clinical outcome, but the clinical relevance of OH recovery assessed using the widely available sphygmomanometer is still unclear. <b><i>Method:</i></b> 635 geriatric outpatients underwent comprehensive geriatric assessment, including orthostatic BP measurements using a sphygmomanometer, during supine rest and 1 and 3 min after standing up and assessment of physical performance (i.e., the timed up and go test and the Short Physical Performance Battery) and the number of falls in the past year. The association between BP recovery, defined as BP at 3 min minus BP at 1 min after standing up, with physical performance and falls was assessed using regression analyses, adjusting for age and sex, both in the entire cohort and after stratifying for the presence of OH at 1 min after standing up. <b><i>Results:</i></b> BP recovery was not associated with physical performance or number of falls, neither in the entire cohort, nor in subpopulations with or without OH. <b><i>Conclusion:</i></b> The clinical relevance of BP recovery between 1 and 3 min after standing up could not be demonstrated. The results suggest that sphygmomanometer measurements have an inadequate time resolution to record the clinically relevant dynamics of orthostatic BP recovery.

Introduction: While retrospective studies have shown that poor control of vascular risk factors is associated with progression of white matter hyperintensity (WMH), it has not been studied prospectively. Hypothesis: We hypothesize that higher systolic blood pressure (SBP) mean, LDL cholesterol, and Hgb A1c will be correlated with WMH progression in diabetics. Methods: This is a secondary analysis of the Memory in Diabetes (MIND) substudy of the Action to Control Cardiovascular Risk in Diabetes Follow-on Study (ACCORDION). The primary outcome was WMH progression, evaluated by fitting linear regression models to the WMH volume on the month 80 MRI and adjusting for the WMH volume on the baseline MRI. The primary predictors were the mean values of SBP, LDL, and A1c from baseline to month 80. We defined a good vascular risk factor profile as mean SBP <120 mm Hg and mean LDL <120 mg/dL. Results: We included 292 patients, with a mean (SD) age of 62.6 (5.3) years and 55.8% male. The mean number of SBP, LDL, and A1c measurements per patient was 17, 5, and 12. We identified 86 (29.4%) patients with good vascular risk factor profile. In the linear regression models, mean SBP and LDL were associated with WMH progression and in a second fully adjusted model they both remained associated with WMH progression (Table). Those with a good vascular risk factor profile had less WMH progression (β Coefficient -0.80, 95% CI -1.42, -0.18, p=0.012). Conclusions: Our data reinforce prior research showing that higher SBP and LDL is associated with progression of WMH in diabetics, likely secondary to chronic microvascular ischemia, and suggest that control of these factors may have protective effects. This study has unique strengths, including prospective serial measurement of the exposures, validated algorithmic measurement methodology for WMH, and rigorous adjudication of study data. Clinical trials are needed to investigate the effect of vascular risk factor reduction on WMH progression.
