The Impact

Background: We aimed to analyse the impact of elevated systolic blood pressure (SBP) levels on mortality and life expectancy among ≥25 yr adults in the municipality of Ningbo, China. Methods: The death cause data were collected from the Internet-based Comprehensive Chronic Disease Surveillance System in Zhejiang Province in 2015, and SBP level data were obtained from the Ningbo Adult Chronic Disease Surveillance survey. According to the comparative risk assessment theory, the population attributable fraction (PAF) of elevated SBP levels by gender and urban-rural regions has been calculated. The deaths and life expectancy loss due to elevated SBP levels were estimated. Results: In 2015, the average SBP level among ≥25 yr adults in Ningbo was 129.01 ± 17.73 mmHg, which was higher in men (131.67 ± 16.89 mmHg) than in women (126.24 ± 18.15 mmHg) and was higher among adults in rural regions (130.55 ± 18.75 mmHg) than among adults in urban regions (127.15 ± 16.19 mmHg). A total of 6181 deaths were attributed to elevated SBP levels among adults in Ningbo. The PAF of deaths caused by elevated SBP levels among adults was 16.14%, which was higher in women (18.73%) than in men (14.31%). The overall loss of life expectancy caused by elevated SBP levels among adults was 1.76 yr, which was higher in women (1.99 yr) than in men (1.53 yr) and was higher in rural regions (1.91 yr) than in urban regions (1.49 yr). Conclusion: Elevated SBP levels had a serious impact on the death and life expectancy loss of residents in Ningbo.

The current study evaluated the impact of a whole-foods, plant-based nutrition intervention on metabolic markers of patients with chronic disease in an underserved community setting. A retrospective analysis of metabolic biomarkers preintervention and postintervention was conducted on 31 patients with metabolic disease who attended an Eating for Life group visit series. Significant decreases were found for body mass index (BMI; −0.66 [−0.91 to −0.40] kg/m2), systolic blood pressure (−12 [−19 to −5] mm Hg), total cholesterol (−20 [−29 to −10] mg/dL), low-density lipoprotein (LDL; −11.6 [−17.5 to −5.5] mg/dL), and high-density lipoprotein (HDL; −3.2 [−5.7 to −0.7] mg/dL, all Ps < .01). In participants with clinically abnormal preintervention data, the mean (95% CI) change significantly decreased for overweight (−0.45 [−0.85 to −0.05]) and obese (−0.76 [−1.13 to −0.39]) BMI, systolic blood pressure (−12 [−19 to −5] mm Hg), total cholesterol −22 [−40 to −4] mg/dL), and LDL (−15.6 [−23.8 to −7.4] mg/dL, all Ps ≤ .03). In conclusion, the Eating for Life model showed significant improvement in BMI, diastolic blood pressure, total cholesterol, and LDL in a federally qualified health center population. Group visits advocating for a whole-foods, plant-based diet may be effective in reducing chronic disease burden in underserved communities.

Abstract We reported previously that overexpression of heterogeneous nuclear ribonucleoprotein F (Hnrnpf) in renal proximal tubular cells (RPTCs) suppresses angiotensinogen (Agt) expression, and attenuates systemic hypertension and renal injury in diabetic Hnrnpf-transgenic (Tg) mice. We thus hypothesized that deletion of Hnrnpf in the renal proximal tubules (RPT) of mice would worsen systemic hypertension and kidney injury, perhaps revealing novel mechanism(s). Tubule-specific Hnrnpf knockout (KO) mice were generated by crossbreeding Pax8-Cre mice with floxed Hnrnpf mice on a C57BL/6 background. Both male and female KO mice exhibited elevated systolic blood pressure, increased urinary albumin/creatinine ratio, tubulo-interstitial fibrosis and glycosuria without changes in blood glucose or glomerular filtration rate compared with control littermates. However, glycosuria disappeared in male KO mice at the age of 12 weeks, while female KO mice had persistent glycosuria. Agt expression was elevated, whereas sodium-glucose co-transporter 2 (Sglt2) expression was down-regulated in RPTs of both male and female KO mice as compared to control littermates. In vitro, KO of HNRNPF in human RPTCs (HK-2) by CRISPR gRNA up-regulated AGT and down-regulated SGLT2 expression. The Sglt2 inhibitor canagliflozin treatment had no effect on Agt and Sglt2 expression in HK-2 and in RPTCs of wild-type mice but induced glycosuria. Our results demonstrate that Hnrnpf plays a role in the development of hypertension and glycosuria through modulation of renal Agt and Sglt2 expression in mice, respectively.

The Impact

Objective: Emotional states are expressed in body and mind through subjective experience of physiological changes. In previous work, subliminal priming of anger prior to lexical decisions increased systolic blood pressure (SBP). This increase predicted the slowing of response times (RT), suggesting that baroreflex-related autonomic changes and their interoceptive (feedback) representations, influence cognition. Alexithymia is a subclinical affective dysfunction characterized by difficulty in identifying emotions. Atypical autonomic and interoceptive profiles are observed in alexithymia. Therefore, we sought to identify mechanisms through which SBP fluctuations during emotional processing might influence decision-making, including whether alexithymia contributes to this relationship. Methods Thirty-two male participants performed an affect priming paradigm and completed the Toronto Alexithymia Scale. Emotional faces were briefly presented (20ms) prior a short-term memory task. RT, accuracy and SBP were recorded on a trial-by-trial basis. Generalized mixed-effects linear models were used to evaluate the impact of emotion, physiological changes, alexithymia score, and their interactions, on performances. Results A main effect of emotion was observed on accuracy. Participants were more accurate on trials with anger primes, compared to neutral priming. Greater accuracy was related to increased SBP. An interaction between SBP and emotion was observed on RT: Increased SBP was associated with RT prolongation in the anger priming condition, yet this relationship was absent under the sadness priming. Alexithymia did not significantly moderate the above relationships. Conclusions Our data suggest that peripheral autonomic responses during affective challenges guide cognitive processes. We discuss our findings in the theoretical framework proposed by Lacey and Lacey (1970).

The Relationship

Background: Household air pollution from biomass fuel use affects 3 billion people worldwide. There are few studies that examine the relationship between biomass fuel use and blood pressure. We sought to determine if daily biomass fuel use was associated with higher blood pressure and increased hypertension in Peru. Methods: We analyzed baseline information from an age- and sex-matched, population-based study in Puno, Peru. Daily biomass fuel use was self-reported. Hypertension was defined as a systolic blood pressure (SBP) ≥140 mmHg; diastolic blood pressure (DBP) ≥90 mmHg; or self-report of diagnosis and anti-hypertensive medications. We used linear and logistic multivariable regressions, adjusting for age, sex, daily cigarette use and body mass index, to examine the relationship between daily biomass fuel use with blood pressure and hypertension, respectively. Results: Data from 1004 individuals (mean age 55.3 years, 51.7% female) were included. There was evidence of an association between daily biomass fuel use and hypertension (adjusted OR = 2.1, 95%CI 1.2 to 3.5). Subjects who reported daily use of biomass fuels had 6.0 mmHg (95% CI 4.1 to 8.0) higher SBP and 4.8 mmHg (95%CI 3.5 to 6.0) higher DBP compared to those who did not use biomass fuels daily. In a secondary analysis, we used rural residence (vs. urban) as a proxy of biomass daily use and the relationship with hypertension and systolic blood pressure was similar: a higher odds of hypertension (adjusted OR = 2.1, 95%CI 1.3 to 3.6), and higher SBP (6.7mmHg, 95% CI 4.8 to 8.6) and DBP (5.5 mmHg, 95% CI 4.3 to 6.8) in rural vs. urban participants. Conclusion: Biomass fuel use is associated with increased odds of hypertension and higher blood pressure in Puno, Peru. Reducing exposure to air pollution from biomass fuel use represents a potential opportunity for cardiovascular prevention in rural communities worldwide. Longitudinal studies to evaluate the impact of reducing household air pollution are needed.

Wall Lesions

Objectives. We sought to assess acute changes in systemic and pulmonary hemodynamics and microscopic artery lesions following extended renal artery denervation (RDN). Background. RDN has been proposed to reduce sympathetic nervous system hyperactivation. Although the effects of RDN on systemic circulation and overall sympathetic activity have been studied, data on the impact of RDN on pulmonary hemodynamics is lacking. Methods. The study comprised 13 normotensive Landrace pigs. After randomization, 7 animals were allocated to the group of bilateral RDN and 6 animals to the group of a sham procedure (SHAM). Hemodynamic measures, cannulation, and balloon-based occlusion of the renal arteries were performed in both groups. In the RDN group, radiofrequency ablation was performed in all available arteries and their segments. An autopsy study of the renal arteries was carried out in both groups. Results. The analysis was performed on 12 pigs (6 in either group) since pulmonary thromboembolism occurred in one case. A statistically significant drop in the mean diastolic pulmonary artery pressure (PAP) was detected in the RDN group when compared with the SHAM group (change by 13.0 ± 4.4 and 10.0 ± 3.0   mmHg , correspondingly; P = 0.04 ). In 5 out of 6 pigs in the RDN group, a significant decrease in systemic systolic blood pressure was found, when compared with baseline ( 98.8 ± 17.8 vs. 90.2 ± 12.6   mmHg , P = 0.04 ), and a lower mean pulmonary vascular resistance (PVR) ( 291.0 ± 77.4 vs. 228.5 ± 63.8   dyn ∗ sec ∗ c m − 5 , P = 0.03 ) after ablation was found. Artery dissections were found in both groups, with prevalence in animals after RDN. Conclusions. Extensive RDN leads to a rapid and significant decrease in PAP. In the majority of cases, RDN is associated with an acute lowering of systolic blood pressure and PVR. Extended RDN is associated with artery wall lesions and thrombus formation underdiagnosed by angiography.

Abstract Background Authoritative medical and public health agencies in most countries advise to reduce population dietary salt intake to under 5–6 g/day as a strategy for preventing high blood pressure and cardiovascular disease. However, there is still dispute about whether salt reduction should be adopted by all populations. In addition, the effect of duration of dietary salt reduction has not been sufficiently investigated. Purpose To understand the effect of dietary salt reduction on blood pressure and the impact of intervention duration. Methods A systematic review and meta-analysis was conducted. Randomized controlled trials that allocated participants to low and high salt intake, without confounding from unequal concomitant interventions, were included. We excluded studies done in individuals younger than 18 years, pregnant women, individuals with renal disease or heart failure, and studies with sodium excretion estimated from spot urine. Random effect meta-analysis was used to generate pooled estimates of the effect on 24-hour urinary sodium excretion, systolic and diastolic blood pressure. Multivariate meta-regression was used to quantify the dose response effect of dietary salt on blood pressure change and to understand the impact of the intervention duration. Results 125 studies were included with 162 data points extracted. Ninety-nine data points (61%) had interventions under 4 weeks. Overall, 24-hour urinary sodium excretion changed by −141 mmol (95% CI: −156; −126), systolic blood pressure changed by −4.4 mm Hg (95% CI: −5.2; −3.7) and diastolic blood pressure changed by −2.4 mm Hg (95% CI: −2.9; −1.9). Sodium reduction resulted in a significant decrease of systolic blood pressure in all subgroups except in participants with low baseline sodium intake (<109 mmol) (Figure 1). Each 100 mmol reduction of sodium was associated with 2.7 mm Hg (95% CI: 1.0; 4.4; p=0.002) reduction of systolic blood pressure and 1.2 mm Hg (95% CI: 0.0; 2.4; p=0.046) reduction of diastolic blood pressure after adjusting for intervention duration, age, sex, race, baseline blood pressure, baseline sodium intake and interaction between age and baseline blood pressure. For the same amount of salt reduction, a 10 mm Hg higher baseline systolic blood pressure would result in 2.5 mm Hg greater reduction of systolic blood pressure. There is not enough evidence to show the impact of intervention duration. Figure 1 Conclusions Our meta-analysis showed that sodium reduction could reduce blood pressure in all adult populations regardless of age, sex and race. The effect of salt reduction on systolic blood pressure increases with higher baseline blood pressure. Further studies, designed to investigate the impact of intervention duration, are needed to understand the significance of the duration. Acknowledgement/Funding None
