BACKGROUND While there is a strong association between adhering to a healthy dietary pattern and reductions in blood pressure, adherence still remains low. New technologies aimed to help facilitate behavior change may have an effect on reducing blood pressure among individuals with hypertension. OBJECTIVE To evaluate characteristics of participants with stage 2 hypertension who used Foodsmart and to assess changes in systolic blood pressure (SBP) and diastolic blood pressure (DBP). METHODS We analyzed demographic, dietary, and clinical characteristics collected from 11,934 adults with at least two blood pressure readings who used the Foodsmart platform. Stage 2 hypertension was defined as SBP ≥ 140 mmHg or DBP ≥ 90 mmHg. We calculated mean changes in blood pressure among participants with stage 2 hypertension and stratified by length of follow-up and the covariates associated with achieving blood pressure levels below stage 2 hypertension. We compared changes in diet quality and weight between participants with stage 2 hypertension at baseline who achieved stage 1 hypertension or below and those who did not. RESULTS We found that 47.2% (5,627/11,934) and 10.6% (1,269/11,934) of the participants with at least two SBP and DBP readings had stage 1 and stage 2 hypertension, respectively, at baseline. Among Foodsmart participants with stage 2 hypertension at baseline, SBP and DBP had an absolute reduction, on average, of 5.6 mmHg and 4.0 mmHg, respectively. 33.0% (419/1,269) of participants with stage 2 hypertension at baseline achieved blood pressure levels below stage 2 hypertension (SBP < 140 mmHg and DBP < 90 mmHg). Using a multivariable ordinal logistic regression model, changes in Nutriscore and weight were statistically significantly associated with changes in blood pressure levels for users with stage 2 hypertension at baseline. Using a multivariable logistic regression model, we found that baseline Nutriscore, change in Nutriscore, and change in weight were all associated with the likelihood of users with stage 2 hypertension at baseline to achieve a lower blood pressure category. Among Foodsmart participants with stage 2 hypertension at baseline, systolic blood pressure and diastolic blood pressure had an absolute reduction, on average, of 5.6 mm Hg and 4.0 mm Hg, respectively. 33.0% (419/1,269) of participants with stage 2 hypertension at baseline achieved blood pressure levels of stage 1 hypertension (systolic blood pressure < 140 mm Hg and diastolic blood pressure < 90 mm Hg) in their last blood pressure entry. CONCLUSIONS This study evaluated changes in SBP and DBP among users of the Foodsmart platform with hypertension and found that users with stage 2 hypertension, on average, improved their blood pressure levels over time.

Postmenopausal women have a higher prevalence of hypertension compared to premenopausal women. Hypertension is a risk factor for cardiovascular diseases, the prevalence of which is ever increasing. This study investigated the effects of long-term acupuncture on lowering the blood pressure of postmenopausal women with prehypertension and stage 1 hypertension. Participants were 122 postmenopausal women aged less than 65 years, diagnosed with prehypertension or stage 1 hypertension (systolic blood pressure 120–159 mmHg or diastolic blood pressure 80–99 mmHg). We used a propensity score-matched design. The experimental group (n = 61) received acupuncture for four weeks every six months over a period of two years. The control group (n = 61) received no intervention. An Analysis of covariance (ANCOVA) was performed for the primary efficacy analysis. Relative risk ratios were used to compare group differences in treatment effects. Acupuncture significantly reduced the participants’ diastolic blood pressure (−9.92 mmHg; p < 0.001) and systolic blood pressure (−10.34 mmHg; p < 0.001) from baseline to follow-up. The results indicate that acupuncture alleviates hypertension in postmenopausal women, reducing their risk of developing cardiovascular diseases and improving their health and quality of life.

Cox proportional hazard regression is a regression model that is often used in survival analysis. Survival analysis is phrase used to describe analysis of data in the form of times from a well-defined time origin until occurrence of some particular even or end-point. In analysis survival sometimes ties are found, namely there are two or more individual that have together event. This study aims to apply Cox model on ties event using two methods, Breslow and Efron and determine factors that affect survival of stroke patients in Tugurejo Hospital Semarang. Dependent variable in this study is length of stay, then independent variables are gender, age, type of stroke, history of hypertension, systolic blood pressure, diastolic blood pressure, blood sugar levels, and BMI. The two methods give different result, Breslow has four significant variables there are type of stroke, history of hypertension, systolic blood pressure, and diastolic blood pressure, while Efron contains five significant variables such as type of stroke, history of hypertension, systolic blood pressure, diastolic blood pressure and blood sugar levels. From the smallest AIC criteria obtained the best Cox proportional hazard regression model is Efron method. Keywords: Stroke, Cox Proportional Hazard Regression model, Breslow method, Efron method.

Abstract Objectives The objectives of this study were to examine the dietary salt-related knowledge, attitudes, and behaviors associated with the prevalence of hypertension among adults residing in rural Northern Thailand. Methods A cross-sectional study utilizing convenience sampling was administered in San Pa Tong District, Chiang Mai, Thailand. The one-on-one interview was conducted to assess subject's knowledge, attitudes, and behaviors relating to their dietary salt intake. Various food frequencies for foods high in salt were also measured. Each subject's blood pressure was measured twice before and after the interview. A logistic regression model was used in the analysis to determine potential hypertension risk factors. Results A total of 403 adults participated in the study. A majority of participants were female (73.2%), and the average age was 62.5 years old. Half of participants reported a family history of hypertension and 32% of participants were hypertensive. The major results from the logistic regression model indicated positive attitudes towards decreasing salt intake lead to a lower chance of becoming hypertensive (OR = 0.934). However, a family history of high blood pressure (OR = 1.417), a higher knowledge score about foods high in salt (OR = 1.254), daily use of Monosodium Glutamate (MSG) in food preparation (OR = 1.959) and buying outside food to eat at home (OR = 5.692) lead to a higher chance of becoming hypertensive. Conclusions Our findings suggest higher knowledge does not decrease the chance of becoming hypertensive. However, there is a positive association between hypertension and dietary salt-related behaviors among adults living in rural Thai communities. More specifically, salt-reduction interventions should focus on promoting home-cooked meal preparation with lower salt substitutes to MSG.

Background. Emergency physicians (EPs) face critical admission decisions, and their judgments are questioned in some developing systems. This study aims to define the factors affecting mortality in patients admitted to the hospital by EPs against in-service departments’ decision and evaluate EPs’ admission diagnosis with final discharge diagnosis. Methods. This is a retrospective analysis of prospectively collected data of ten consecutive years (2008–2017) of an emergency department of a university medical center. Adult patients (≥18 years-old) who were admitted to the hospital by EPs against in-service departments’ decision were enrolled in the study. Significant factors affecting mortality were defined by the backward logistic regression model. Results. 369 consecutive patients were studied, and 195 (52.8%) were males. The mean (SD) age was 65.5 (17.3) years. The logistic regression model showed that significant factors affecting mortality were intubation (p<0.0001), low systolic blood pressure (p=0.006), increased age (p=0.013), and having a comorbidity (p=0.024). There was no significant difference between EPs’ primary admission diagnosis and patient’s final primary diagnosis at the time of disposition from the admitted departments (McNemar–Bowker test, p=0.45). 96% of the primary admission diagnoses of EPs were correct. Conclusions. Intubation, low systolic blood pressure on presentation, increased age, and having a comorbidity increased the mortality. EPs admission diagnoses were highly correlated with the final diagnosis. EPs make difficult admission decisions with high accuracy, if needed.

Aims The aim of this study was to evaluate the associations of blood pressure categorization based on the 2017 American College of Cardiology and American Heart Association guideline with the risk of peripheral artery disease (PAD). Methods Among 13,113 middle-aged participants, we investigated the associations of 2017 blood pressure categories (systolic <120 and diastolic <80 mmHg (normal if no anti-hypertensive medications; reference), 120–129 and <80 (elevated), 130–139 and/or 80–89 (stage 1 hypertension), and ≥140 and/or ≥90 (stage 2 hypertension)) with incident PAD (hospitalizations with a diagnosis or leg revascularization) using Cox regression models. Analyses were separately conducted in individuals with and without anti-hypertensive medications. Results During a median follow-up of 25.4 years, 466 incident PAD occurred (271 cases in 9858 participants without anti-hypertensive medications). In participants without anti-hypertensive medications, we observed significant hazard ratios of PAD in elevated blood pressure (1.80 (1.28–2.51)) and stage 2 hypertension (2.40 (1.72–3.34)), but not in stage 1 hypertension. Analyzing systolic and diastolic blood pressure separately, higher systolic blood pressure categories showed significant associations with incident PAD in a graded fashion whereas, for diastolic blood pressure, only ≥90 mmHg did. Generally similar patterns were seen among participants on anti-hypertensive medication, while they had higher risk of PAD than those without at each blood pressure category. Conclusions Systolic blood pressure, including the category of 130–139 mmHg, showed stronger associations with incident PAD than did diastolic blood pressure. Consequently, elevated blood pressure conferred similar or even greater risk of PAD than stage 1 hypertension, with implications on how to interpret new blood pressure categories in terms of leg vascular health.

Introduction: Age and systolic blood pressure (SBP) are important predictors of Acute Cerebrovascular Syndrome (ACVS). Yet, the effect of SBP is confounded by age, making its independent contribution to ACVS risk difficult to quantify. Here we use logistic regression to explore the role of SBP in younger and older ED patients. Methods: Data comprised 1019 ED patients (ACVS 70%, 30% non-ACVS) enrolled during a 28-month period of an ongoing prospective, observational, multi-site stroke biomarker study (SpecTRA). We used logistic regression to examine the effects of age, sex, and the age:SBP interaction as predictive markers of the diagnosis of ACVS. Results: Participants (53% male) ranged in age from 18 to 97 years (Q1=58, median=70, Q3=80). SBP ranged from 84 to 248 mmHg (Q1=137, median=154, Q3=174). In our initial regression model, age, sex, SBP and the age:SBP interaction were all significant (p&lt;0.01). Using cubic regression splines for age, sbp and their interaction yields the same conclusion (p&lt;0.01). To better understand the role of SBP in younger vs. older patients, we stratified the sample at the median age (70 years of age). In the younger group (n=510), participants were 55% male, 60% ACVS, and had SBP ranging from 91 to 236 mmHg (Q1=133, median=148, Q3=165). In the older group (n=509), participants were 51% male, 82% ACVS and had SBP ranging from 84 to 248 mmHg (Q1=143, median=159, Q3=179), a shift of approximately 10 mmHg between the groups. The logistic regression model was then fit separately to each group without the age:SBP interaction term. In the younger group, we found SBP to be highly significant (p&lt;0.001), with an odds-ratio (OR) of 1.18 per 10 mmHg (95% CI: 1.10-1.29). In the older group, we found that SBP was not significant (p=0.91), with an OR of 1.00 per 10 mmHg (95% CI: 0.91-1.08). Age and sex were also significant risk factors in the younger group (each p&lt;0.01), though not in the older group (both p&gt;0.07). Conclusion: Our findings suggest that for ED patients suspected of ACVS, SBP is a clinically relevant predictor for younger patients, with higher SBP associated with an increased risk of ACVS, regardless of patient age and sex. SBP does not appear to be a strong predictor for patients over 70. ED physicians can leverage this finding by attributing greater importance to elevated SBP in younger patients than older patients when working toward a clinical suspicion of ACVS.

Abstract This study determines the associations among serum lipid profiles, risk of cardiovascular disease, and persistent organic pollutants. Using Gas chromatography technique, the intensity of toxic pollutant residues in serum samples of Hypertensive patients were measured. Based on statistical analysis, the effects of different covariates namely pesticides, age, systolic blood pressure, diastolic blood pressure, and lipid profile duration was checked using the logistic regression model. Statistical computation was performed on SPSS 22.0. The P-values of F-Statistic for each lipid profile class are greater than 0.01 (1%), therefore we cannot reject the null hypothesis for all cases. The estimated coefficients, their standard errors, Wald Statistic, and odds ratio of the binary logistic regression model for different lipid profile parameters indicate if pesticides increase then the logit value of different lipid profile parameters changes from -0.46 to -0.246 except LDL which increases by 0.135. The study reports a significantly increased threat of cardiovascular disease with increased concentrations of toxic pollutants.

The American College of Cardiology/American Heart Association (ACC/AHA) updated its guideline redefining the classification of hypertension and the blood pressure cut-off in 2017. The current cut-offs for stage 1 hypertension of 130 mm Hg systolic blood pressure or 80 mm Hg diastolic blood pressure replace the previous cut-offs of 140 mm Hg systolic blood pressure or 90 mm Hg diastolic blood pressure which were based on the ACC/AHA guidelines from 1988. However, the blood pressure cut-off for the obstetric population still remains as 140/90 mm Hg despite the scarcity of evidence for it. Recent American College of Obstetricians and Gynecologists (ACOG) bulletins for pregnant women have not reflected the new ACC/AHA change of guideline. We reviewed a mounting body of evidence prompting the implementation of the new ACC/AHA guidelines for the obstetric population. These studies examined maternal and fetal outcomes applying the new ACC/AHA guidelines during antepartum or postpartum care.

Abstract Background Chorioamnionitis is associated with various neonatal short- and long-term morbidities. The effect of chorioamnionitis on premature children’s outcomes remains controversial. The aim of this study is to investigate the relationship between histological chorioamnionitis (HCA) and physiological development, wheezing, and atopic diseases in preterm children. Methods Singleton, preterm children (< 34 weeks), whose mother underwent pathological placental examinations, were retrospectively enrolled and the outcomes were assessed at 24–40 months during follow-up. Wheezing and atopic diseases including eczema, food allergies, and allergic rhinitis were screened by a questionnaire along with medical diagnosis. Anthropometric indexes and blood pressure were measured. Cognitive and behavioural developments were assessed by the Gesell Development and Diagnosis Scale. Blood IgE and routine examination were analyzed with venous blood and serum metabolomic profiling was assessed via liquid chromatography-mass spectrometry (LC-MS). A multivariate logistic regression model was used to estimate the association between HCA and the current outcomes. Results Among the 115 enrolled children, 47 were exposed to HCA. The incidence of wheezing was significantly higher in children exposed to HCA, as 38.30% of children who were exposed to HCA and 16.18% of children who were not had been diagnosed with wheezing. After adjusting for related confounders in the multivariate logistic regression model, there remained a 2.72-fold increased risk of wheezing in children with HCA (adjusted odds ratio, aOR, 2.72; 95% confidence interval, 1.02–7.23). Moreover, 163 differential metabolites, such as butanoic acid, annotemoyin 1 and charine, were identified in the HCA exposed children’s serum. Enrichment analysis revealed that these compounds participated in diverse key metabolomic pathways relating to physical and neuro- developments, including glycerophospholipid, alpha-linolenic acid and choline metabolisms. There were no significant differences in atopic diseases, serum IgE, eosinophils’ level, anthropometric indexes, blood pressure, or cognitive or behavioural developments between the two groups. Conclusion HCA exposure is associated with an increased risk of wheezing in preterm children less than 34 gestational weeks.

The aim of the study was to determine the effectiveness of giving hydrotherapi foot soak in hypertensive patients. The study was conducted with one group pretestposttest design without a control group by measuring blood pressure (pretest) before being given an intervention in the form of foot soak hydrotherm against 15 people with hypertension in Banjar Sri Mandala, Dauhwaru Village, Jembrana Subregency. Then do the blood pressure measurement again (posttest) after finishing the intervention. After the study was completed, the results showed that before the hydrotherapi foot bath intervention, there were 0% of patients classified as normal, 13.32% in prehypertension category, 60.08% in hypertension category I and 26.60% in hypertension category II. After the intervention was given, there were 13.32% of the patients classified as normal, 66.68% in the prehypertension category, 20.00% in the first category of hypertension and no patients belonging to the second grade hypertension category. There is a decrease of 20-30 mmHg for systolic blood pressure and 0-10 mmHg for diastolic blood pressure after intervention. Based on the results of the study it can be concluded that the hydrotherapi foot bath is effectively used to reduce blood pressure in hypertensive patients in the Banjar Sri Mandala, Dauhwaru Village, Jembrana District.
