1. Possible associations between maternal nutrition in pregnancy and non-communicable diseases of adulthood were assessed using a rat model. Rats were habituated to diets containing a range of protein levels (18, 12, 9 and 6% by weight), over a 14 day period, before mating. The low protein diets were maintained throughout pregnancy. Lactating mothers and their offspring were transferred to a standard chow diet (20% protein). 2. Pregnant rats demonstrated a graded response to the diets, with those fed 9 and 6% protein tending to consume less energy and gain less weight than 18% protein fed controls. Litter size and newborn death rates were not significantly altered by the low protein diets. 3. Offspring of 12 and 9% protein fed dams were grossly normal, gaining weight at a similar rate to those born to 18% protein fed control rats. Offspring of the 6% protein fed dams were smaller than pups from all other groups, over a 21 week period. 4. At 9 weeks of age, systolic blood pressure was determined in the offspring. All offspring from the three low protein groups were found to have significantly elevated blood pressure (15–22 mmHg) relative to the control group. An inverse relationship between maternal protein intake and the systolic blood pressure of the offspring was observed. Blood pressure remained elevated in the offspring of the 9 and 6% protein fed dams until 21 weeks of age. The observed hypertension was associated with increased pulmonary angiotensin-converting enzyme activity in the low protein groups. 5. The data are consistent with the hypothesis that poor maternal nutrition in pregnancy may irreversibly impair aspects of physiological and biochemical function in the fetus. This has potential adverse consequences for the later health of the offspring.

1. In the rat low birthweight and raised systolic blood pressure are the consequence of fetal exposure to maternal low protein diets. Nutritional down-regulation of the placental isoform of 11β-hydroxysteroid dehydrogenase, which may increase exposure of the fetus to maternal glucocorticoids, has been suggested to underlie effects of low protein diets on fetal growth and blood pressure. 2. Pregnant rats were fed control (18% casein) or low protein (9% casein) diets throughout gestation. Animals fed the control diet were injected with carbenoxolone, an inhibitor of 11β-hydroxysteroid dehydrogenase. Injections were administered either throughout pregnancy (days 0–22), or targeted to specific periods in early (days 0–7), mid- (days 8–14) or late (days 15–22) gestation. 3. Exposure to a low protein diet reduced birthweight and at 4 weeks of age systolic blood pressure was significantly elevated in the rats exposed to low protein. These hypertensive animals had small kidneys in proportion to body weight. 4. Fetal exposure to carbenoxolone at any period in gestation resulted in lower weight at birth. In rats exposed to the inhibitor over days 8–14, 15–22 or 0–22 systolic blood pressure at 4 weeks was significantly higher than in control animals. The greatest elevation of pressure was associated with carbenoxolone treatment in late (days 15–22) gestation. Animals with carbenoxolone-induced hypertension did not exhibit evidence of retarded renal growth. 5. Increased fetal exposure to maternal glucocorticoids impairs fetal growth and programmes elevated blood pressure in later life.

The present study examined whether a prenatal low-protein diet programs a decrease in glomerular filtration rate (GFR) and an increase in systolic blood pressure (BP). In addition, we examined whether altering the postnatal nutritional environment of nursing neonatal rats affected GFR and BP when rats were studied as adults. Pregnant rats were fed a normal (20%) protein diet or a low-protein diet (6%) during the last half of pregnancy until birth, when rats were fed a 20% protein diet. Mature adult rats from the prenatal low-protein group had systolic hypertension and a GFR of 0.38 ± 0.03 versus 0.57 ± 0.05 ml·min−1·100 g body wt−1 in the 20% group ( P < 0.01). In cross-fostering experiments, mothers continued on the same prenatal diet until weaning. Prenatal 6% protein rats cross-fostered to a 20% mother on day 1 of life had a GFR of 0.53 ± 0.05 ml·min−1·100 g body wt−1, which was not different than the 20% group cross-fostered to a different 20% mother (0.45 ± 0.04 ml·min−1·100 g body wt−1). BP in the 6% to 20% group was comparable with the 20% to 20% group. Offspring of rats fed either 20% or 6% protein diets during pregnancy and cross-fostered to a 6% mother had elevated BP but a comparable GFR normalized to body weight as the 20% to 20% control group. Thus, a prenatal low-protein diet causes hypertension and a reduction in GFR in mature adult offspring, which can be modified by postnatal rearing.

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.

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.

Abstract Aim: To evaluate the effectiveness of an intervention in primary health care designed to increase physical activity in people with dementia and their family caregivers.Methods: A cluster-randomized multicentre clinical trial was carried out.Participants: 140 people with dementia (median age 82 years;63.6% women) and 176 caregivers (median age 62 years ;72.7% women). Seventy patients and 80 caregivers were assigned to the Control Group (CG) and 70 patients and 96 caregivers to the Intervention Group (IG). The physical activity was measured with the pedometer and with the IPAQ-SF questionnaire. The intervention consisted of applying in primary care the program promoting physical activity (PEPAF) for 3 months. The changes observed at 6 months were analyzed. Results:In people with dementia, in the pedometer assessment a decrease was observed in both groups, but it was larger in the CG both in the total number step/day lower in the IG than in the CG and in the aerobic steps / day (52.89 vs -615.93). The activity reported with the IPAQ-SF decreased more in IG, both in the MET/min/week (-258.470 vs -148.23) and in the MVPA min/week. In caregivers the pedometer assessment showed that total steps/day increased more in the IG, as did aerobic steps/day (356.91 vs -12.95). The IPAQ-SF a smaller increase in global activity was declared in the IG than in the CG (545.25 MET/min/week vs 609.55), but the increase in vigorous activity was greater. No differences were found in changes in the functional status and the cognitive performances of people with dementia nor in the mental health in the caregivers, but systolic blood pressure, the Family APGAR and overload in the IG did improve.Conclusions: The results suggest that the intervention carried out may be effective on physical activity in both patients and caregivers. It can also improve systolic blood pressure, the Family APGAR and overload in caregivers. This is the first study to implement a primary care intervention aimed at simultaneously increasing physical activity in people with dementia and their relatives. These results reinforce the importance of using objective measures in clinical trials in people with dementia.Trial registration number: NCT 02044887.

With the accelerating pace of life, increasing stress and unhealthy diet make cardiovascular disease one of the important diseases that endanger human health, among which the incidence of acute angina is gradually increasing. At present, there are many clinical treatment studies on acute angina pectoris, but the relevant imaging analysis is very lacking. In order to study the clinical treatment of patients with acute angina pectoris and analyze the relevant medical images, to arrive at a more effective treatment method, this article launched an in-depth study. First, we selected 88 patients with acute angina in a hospital as the research object and randomly divided them into a control group (n = 44) and an experimental group (n = 44) Yan et al. (2020). The control group was treated with conventional acute angina pectoris drugs, while the experimental group was treated with clopidogrel on this basis. The two groups were treated at the same time, and the treatment time lasted for 3 months. Then, the risk factors of the two groups of patients were analyzed, and the differences were statistically significant ( P < 0.05 ). Then, the medical images of the two groups of patients were analyzed, and the diastolic blood pressure, systolic blood pressure, and coronary artery stenosis were compared before and after treatment. After treatment, the diastolic blood pressure and systolic blood pressure of the experimental group were 88.31 ± 3.15 mmHg and 125.63 ± 4.16 mmHg, respectively. The proportion of patients with zero-vessel disease and single-vessel disease in the experimental group increased to 15.91% and 56.82%. The treatment plan received by the experimental group patients had a better improvement effect. Finally, the clinical efficacy was compared. The total effective rates of the control and experimental groups were 72.7% and 88.6%, respectively. This shows that the treatment method adopted by the experimental group of patients has a better curative effect and is worthy of clinical promotion.

Background. Some studies published previously have shown a strong correlation between hypertension and psychological nature including impulsion emotion or mindfulness and relaxation temperament, among which mindfulness and relaxation temperament might have a benign influence on blood pressure, ameliorating the hypertension. However, the conclusion was not confirmed. Objective. The meta-analysis was performed to investigate the influence of mindfulness and relaxation on essential hypertension interventions and confirm the effects. Methods. Systematic searches were conducted in common English and Chinese electronic databases (i.e., PubMed/MEDLINE, EMBASE, Web of Science, CINAHL, PsycINFO, Cochrane Library, and Chinese Biomedical Literature Database) from 1980 to 2020. A meta-analysis including 5 studies was performed using Rev Man 5.4.1 software to estimate the influence of mindfulness and relaxation on blood pressure, ameliorating the hypertension. Publication bias and heterogeneity of samples were tested using a funnel plot. Studies were analyzed using either a random-effect model or a fixed-effect model. Results. All the 5 studies investigated the influence of mindfulness and relaxation on diastolic and systolic blood pressure, with total 205 participants in the control group and 204 in the intervention group. The random-effects model (REM) was used to calculate the pooled effect for mindfulness and relaxation on diastolic blood pressure (I2 = 0%, t2 = 0.000, P = 0.41 ). The random pooled effect size (MD) was 0.30 (95% CI = −0.81–1.42, P = 0.59 ). REM was used to calculate the pooled effect for mindfulness and relaxation on systolic blood pressure (I2 = 49%, t2 = 3.05, P = 0.10 ). The random pooled effect size (MD) was −1.05 (95% CI = −3.29–1.18, P = 0.36 ). The results of this meta-analysis were influenced by publication bias to some degree. Conclusion. All the results showed less influence of mindfulness and relaxation might act on diastolic or systolic blood pressure, when mindfulness and relaxation are used to intervene in treating CVD and hypertension.

Background: Hypertension during pregnancy remains high in Indonesia. It is a major cause of maternal death. Aromatherapy lavender and classical music therapy are considered effective in lowering blood pressure in hypertension.Objective: To examine the effect of lavender aromatherapy and classical music therapy in lowering blood pressure in pregnant women with hypertension.Methods: A quasy experimental study with pretest-posttest control group design. There were 52 pregnant women with the inclusion criteria selected as samples using simple random sampling, divided into lavender aromatherapy group, classical music group, combination of aromatherapy and music group, and control group. Sphygmomanometer was used to measure blood pressure. Mann Whitney and Post Hoc test were used for data analysis.Results: Results showed that four groups have a significant decrease in systolic blood pressure after given intervention with p-value <0.05. The mean decrease of systolic blood pressure among four groups was: lavender group (5.77 mmHg), music group (7.23 mmHg), combination group (9.54 mmHg), and control group (3.67 mmHg); and the mean decrease of diastolic blood pressure was: the lavender group (2.77 mmHg), music group (0.61 mmHg), combination group (8.23 mmHg), and control group (3.42 mmHg).Conclusion: there was a significant effect of lavender aromatherapy and classical music therapy in lowering blood pressure in pregnant women with hypertension. However, the combination of both interventions was more effective than lavender aromatherapy or music therapy alone.
