Medical nutrition therapy provided by a dietitian improves outcomes in adults with prehypertension or hypertension: a systematic review and meta-analysis. Am J Clin Nutr 2024; 119:1417-1442. [PMID: 38641320 DOI: 10.1016/j.ajcnut.2024.04.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 04/10/2024] [Accepted: 04/16/2024] [Indexed: 04/21/2024] Open
Abstract
BACKGROUND Hypertension is an important risk factor for cardiovascular disease (CVD). Interventions with dietitians can help modify dietary intake and reduce hypertension risk. OBJECTIVES We aimed to examine the following research question: In adults with prehypertension or hypertension, what is the effect of medical nutrition therapy (MNT) provided by a dietitian on blood pressure (BP), CVD risk and events, and anthropometrics compared with standard care or no intervention? METHODS MEDLINE, CINAHL, and Cochrane Central databases were searched for randomized controlled trials (RCTs) published in peer-reviewed journals from 1985-2022. Risk of bias was assessed using version 2 of the Cochrane tool for RCTs. Meta-analyses were conducted using the DerSimonian-Laird random-effects model. Certainty of evidence (COE) was assessed for each outcome using the Grading of Recommendations, Assessment and Evaluation method. RESULTS Forty articles representing 31 RCTs were included and analyzed. MNT provided by a dietitian may reduce systolic [mean difference (MD): -3.63 mmHg; 95% confidence interval (CI): -4.35, -2.91 mmHg] and diastolic (MD: -2.02 mmHg; 95% CI: -2.56, -1.49 mmHg) BP (P < 0.001) and body weight (MD: -1.84 kg; 95% CI: -2.72, -0.96 kg; P < 0.001) and improve antihypertensive medication usage, relative risk of stroke (MD: 0.34; 95% CI: 0.14, 0.81; P = 0.02), and CVD risk score [standardized mean difference (SMD): -0.20; 95% CI: -0.30, -0.09; P < 0.001] compared with control participants, and COE was moderate. Additionally, MNT may reduce arterial stiffness (SMD: -0.45; 95% CI: -0.71, -0.19; P = 0.008) and waist circumference (SMD: -1.18 cm; 95% CI: -2.00, -0.36; P = 0.04), and COE was low. There was no significant difference in risk of myocardial infarction between groups. Dietitian interventions reduced BP and related cardiovascular outcomes for adults with prehypertension or hypertension. CONCLUSIONS Dietitians play a critical role in improving cardiometabolic risk factors for adults with elevated BP; thus, improved payment for and access to MNT services has the potential to significantly impact public health. This review was registered at PROSPERO as CRD42022351693.

Abstract
BACKGROUND Fibroblast growth factor receptor (FGFR)2 expression was decreased in hypertension patients while its role in hypertension was not explored. This experiment aimed to investigate the expression ofFGFR2 in angiotensin II (Ang II)-induced human umbilical vein endothelial cells (HUVECs) and the role of FGFR2 in improving AngII-induced hypertension-related endothelial dysfunction. METHODS AngII-induced HUVECs simulated the hypertension model in vitro. The expression of FGFR2 in Ang II-induced HUVECs and transfected HUVECswas detected by RT-qPCR and western blot. The viability, apoptosis, migration and tube formation ability of Ang II-induced HUVECs were analyzed by Methyl Thiazolyl Tetrazolium (MTT) assay, flow cytometry analysis, wound healing assay and tube formation assay.Detectionof lactate dehydrogenase (LDH), caspase 3, Nitric Oxide (NO) and oxidative stress levels was conducted by assay kits and reactive oxygen species (ROS) level was detected by DCFH-DA assay. The expression of apoptosis-related proteins, protein kinase B(Akt)/nuclear factor E2-related factor 2 (Nrf2)/antioxidant response element (ARE) signaling pathway-related proteins, phospho(p)-endothelial nitric oxide synthase (eNOS) and eNOS was determined by western blot. RESULTS The expression of FGFR2 was decreased in Ang II-induced HUVECs. FGFR2overexpression increased viability, suppressed apoptosis and oxidative stress, and improve endothelial dysfunction of AngII-induced HUVECs through activating the Akt/Nrf2/ARE signaling pathway. MK-2206 (Akt inhibitor) could weaken the effect of FGFR2overexpression to reduce viability, promote apoptosis and oxidative stress, and aggravate endothelial dysfunction of Ang II-inducedHUVECs. CONCLUSION Inconclusion, FGFR2activated the Akt/Nrf2/ARE signaling pathway to improve AngII-induced hypertension-related endothelial dysfunction.

Cardiometabolic, functional, and psychosocial effects of a remotely supervised home-based exercise program in individuals with type 2 diabetes (RED study): study protocol for a randomized clinical trial. Trials 2023; 24:679. [PMID: 37858161 PMCID: PMC10588211 DOI: 10.1186/s13063-023-07704-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Accepted: 10/05/2023] [Indexed: 10/21/2023] Open
Abstract
BACKGROUND Type 2 diabetes mellitus (T2D) is a serious global health problem, and exercise is considered an essential non-pharmacological tool in T2D prevention and treatment. During periods of social isolation experienced by the COVID-19 pandemic, home-based exercise programs were strongly recommended as a strategy to facilitate exercise practice and reduce the negative impacts of social isolation. Remotely supervised exercise stands out as an easily accessible strategy after the pandemic, as it is a tool that aims to facilitate access to exercise by this population. The purpose of the RED study is to verify the effects of a remotely supervised home-based exercise program compared to a control group on cardiometabolic, functional, and psychosocial outcomes in patients with T2D. METHODS Participants are randomized into the control group (CG) and the intervention group (IG). Participants allocated to the CG receive recommendations for the practice of physical activity based on information from chapters of the Physical Activity Guide for the Brazilian Population, while the IG will perform a 12-week home-based exercise program supervised remotely by video call. The intervention has a weekly frequency of two sessions per week on non-consecutive days during the first 6 weeks and three sessions per week on non-consecutive days for the remaining 6 weeks. The RED study has HbA1c as the primary outcome, and the participants' cardiometabolic, functional, and psychosocial parameters are assessed at baseline (week 0) and post-intervention (week 13). DISCUSSION Expected results of the proposed study will provide the knowledge base of health professionals and deliver more evidence for a growing area, i.e., home-based exercise and T2D. Additionally, this protocol aims to verify and demonstrate whether this program can be accessible and effective for different health outcomes in patients with T2D. TRIAL REGISTRATION The RED study protocol was prospectively registered at ClinicalTrials.gov (NCT05362071). Date registered April 6, 2022. https://clinicaltrials.gov/ct2/show/NCT05362071 .

CIENCIA & SAUDE COLETIVA 2023; 28:619-630. [PMID: 36651412 DOI: 10.1590/1413-81232023282.11222022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2021] [Accepted: 08/25/2022] [Indexed: 01/18/2023] Open
Abstract
This study aimed to validate the frequency consumption scale (FCS) and establish cut-off points to assess changes in the eating behavior of participants in the VAMOS Program. The study was based on a community intervention conducted in 2019 in 70 Brazilian cities, with 458 adults from Primary Care. The questionnaire consisted of 12 questions about food frequency consumption. The questions were inserted into the analytical workflow, divided into the descriptive analysis, exploratory and confirmatory factor analysis (EFA), item response theory (IRT) modeling, and construction and validity of an applied questionnaire score. EFA indicated a two-factor structure, with three "healthy" (raw vegetables, fruits, and cooked vegetables) and three "unhealthy" (sugary drinks, sweets, and the replacement of meals with snacks) eating items. Items responses' probabilities indicate a daily consumption of two healthy and once or nonweekly consumption of unhealthy items. Finally, the four categories proposed for FCS can respond over time. Therefore, the FCS proposal can be used effectively for program nutrition evaluation. Furthermore, it is possible to attribute behavior change in Brazilian primary care users with six items.

Abstract
The purpose of the pilot study was to determine the effectiveness of wearable activity trackers alone or in combination with behaviour change strategies for promoting physical activity (PA) among individuals with pre-hypertension or hypertension. A sample of 44 adults (68% female and mean age 55) were randomized to receive either a Fitbit Charge HR 3 alone (FB) or the Fitbit in combination with behaviour change strategies (i.e., goal setting, behaviour goal review, adaptive feedback) delivered by a trained health coach (FB+) for 12 weeks. Moderate and vigorous PA (MVPA), steps, and sedentary time (ST) were assessed using ActiGraph wGT3X-BT. The FB+ group significantly increased PA [+1854 (2518) steps/day, p < .01] and MVPA [+26 (34) mins/day, p < .05], and decreased their ST [-63 (73) mins/day, p < .01]. The FB group significantly increased MVPA [+11 (16) mins/day, p < .05], and decreased their ST [-87 (117) mins/day, p < .01]. Participants in FB+ had a significantly greater increase in MVPA/day compared to FB only with a between-group effect size of 0.6 (p < .05). Using Fitbit for self-monitoring is effective in increasing PA and reducing ST among pre-hypertensive and hypertensive participants. Additional behaviour change support amplified the intervention effectiveness for promoting MVPA.

Abstract
Our aim was to analyze and compare the effects of three different long-term treatments on anthropometric profiles, eating behaviors, anxiety and depression levels, and quality of life of groups of adults with obesity. Methods: The 43 participants in the study were randomly assigned to one of three groups: the education and health group (EH, n = 12), which received lectures on health topics; the physical exercise group (PE, n = 13), which underwent physical training; and the interdisciplinary therapy plus cognitive behavioral therapy (IT + CBT) (n = 18) group, which received physical training, nutritional advice, and physical and psychological therapy. Results: Total quality of life increased significantly in the EH group (△ = 2.00); in the PE group, body weight significantly decreased (△ = -1.42) and the physical domain of quality of life improved (△ = 1.05). However, the most significant changes were seen in the IT + CBT group, in which the anthropometric profile improved; there were an increase in quality of life in all domains (physical, psychological, social, and environmental), an improvement in eating behaviors [Dutch Eating Behavior Questionnaire (DEBQ), total △ = -8.39], and a reduction in depression [Beck Depression Inventory (BDI), △ = -10.13). Conclusion: The IT + CBT program was more effective than the PE and EH programs. Clinical Trial Registration Number: NCT02573688.

Abstract
OBJECTIVE As aging populations increase, many countries have begun implementation of policies to improve elder health and nutrition. This study evaluated key process components of nutrition sections of a national elderly integrated-care program in health-care centers in Iran. METHODS With stratified three-stage random cluster sampling, a total of 256 elderly subjects (clients) and 76 staff members of health-care centers (providers) participated in the study. Quantitative and qualitative data were collected using two self-administrated questionnaires to evaluate various components of process evaluation for clients and providers. Program reach was measured by the ratio of the number in the target group who underwent the program to the number of eligible individuals. Exposure rate was measured as clients' awareness of program services. Delivery and fidelity were assessed from providers' reports for each service. Satisfaction rates were assessed for the whole program and for each service of the program. All reasons behind strengths and weaknesses in each of the process-evaluation components were examined and are reported in detail. RESULTS The clients reported low-reach (20.0%) and moderate-exposure rates of 77.5%, with a program target of 90%. Primary training sessions were delivered to the providers as intended (100%), but most planned services for clients, especially vitamin and mineral supplementation, follow-up, and physical activity sessions, were poorly implemented, as they were delivered correctly to 24.7% (n=63, vitamin and mineral supplementation), 24% (n=62, follow-up), and 40.3% (n=103, physical activity sessions) of the clients, with a set program goal of 60%. An overall low level of implementation fidelity was observed, and 39.3% (n=30) of the providers believed that most clients did not benefit from the nutritional services. Overall, less than half (42.8%, n=101) the clients were highly satisfied with the program. CONCLUSION The process evaluation showed insufficient reach, exposure, and fidelity of the program, as well as imprecise delivery of some services, which resulted in low levels of client satisfaction. The findings may have implications for further reinforcement of the program, and indicate the importance of continuous monitoring and evaluation of such programs.

Abstract
Background Hypertension could induce many serious diseases, including damage to vascular endothelial cells. As a non-coding RNA, long noncoding RNA (lncRNA) has received much attention in scientific research and has a regulating efficacy on many critical life activities in human body. The level of lncRNA AK094457 is thought to be elevated in hypertensive rats. However, there is no research indicating the relationship between the level of lncRNA AK094457 and vascular endothelial injury. Material/Methods In our study, we used lentiviral to knockdown lncRNA AK094457, and the human umbilical vein endothelial cells (HUVECs) were stimulated by the Ang II to imitate the vascular endothelial cell damage caused by hypertension. The Cell Counting Kit-8 assays were used to detect the cells viability. Western blotting was performed to detect the endothelial nitric oxide synthase (eNOS), p-eNOS and endothelin-1 (ET-1). After that the production of the NO was monitored. At last, the reactive oxygen species (ROS) levels and apoptosis rates were detected in this study. Results According to the results, we found that knockdown lncRNA AK094457 could alleviate the decrease of vascular endothelial cell viability induced by angiotensin II (Ang II). The knockdown of lncRNA AK094457 also relieved the downregulation of eNOS and p-eNOS, and the decreasing of NO release. At the same time, the knockdown of lncRNA inhibited the levels of Ang II-induced proinflammatory cytokines (tumor necrosis factor [TNF]-α, interleukin [IL]-1, and IL-6) and cell adhesion molecules (vascular cell adhesion molecule 1 [VCAM-1], intercellular adhesion molecule 1 [ICAM-1], and monocyte chemoattractant protein-1 [MCP-1]). The levels of ROS and apoptosis rates also decreased after the knockdown of lncRNA AK094457. Conclusions All these results indicated that lncRNA AK094457 could promote Ang II-induced vascular endothelial cell injury. On the contrary, knockdown of lncRNA AK094457 could alleviate this damage.

Abstract
Objective To investigate the efficacy of a behavior change program named Vida Ativa Melhorando a Saúde on cardiovascular parameters in hypertensive patients. Methods Ninety hypertensive patients aged over 40 years were randomly allocated to one of two groups: Vida Ativa Melhorando a Saúde or Control (n=45 respectively). Patients in the Vida Ativa Melhorando a Saúde group took part in a behavior change program aimed to encourage changes in physical activity levels and eating habits, according to the Social Cognitive Theory. The program consisted of 90-minute weekly group meetings conducted by a physical therapist and a dietitian. One chapter of the educational material (workbook) provided was discussed per meeting. Participants in the Control Group attended a single educative lecture on lifestyle changes. Brachial and central blood pressure, arterial stiffness and endothelial function parameters were measured pre- and post-intervention. Results Vida Ativa Melhorando a Saúde led to reduction of brachial (131.3±15.8mmHg to 125.1±17.3mmHg; p<0.01) and central (123.6±16.3mmHg to 119.0±20.6mmHg; p=0.02) systolic and brachial diastolic (123.6±16.3mmHg to 119.0±20.6mmHg; p<0.01) blood pressure values, and improvement of post-occlusive reactive hyperemia (from 5.7±2.5mL·100mL−1 to 6.5±2.1mL·100mL−1 tissue·min−1; p=0.04). No changes in body composition, heart rate and arterial stiffness parameters were detected in both groups (p>0.05). Conclusion Vida Ativa Melhorando a Saúde program improved blood pressure and microvascular reactivity in hypertensive patients. Trial registration: ClinicalTrials.gov: NCT02257268

Abstract
ABSTRACT Objective To evaluate the maintenance of the beneficial effects of the Vida Ativa Melhorando a Saúde Program, six months after its completion. Methods A randomized controlled community trial was conducted in two poles of the Academia da Saúde Program, randomly identified as control or intervention groups. The study involved 291 adults and elderly involved in the routine activities of the Academia da Saúde Program. Individuals in the intervention group also participated to the Vida Ativa Melhorando a Saúde Program for 12 weeks. Accelerometers were used to evaluate physical activities, questionnaires for the evaluation of eating habits and anthropometric measures for nutritional status. Results Six months after completion of the intervention, the beneficial results obtained for physical activities and nutritional status were not maintained. The benefits related to eating habits remained, but not exclusively due to the effect of the intervention. Conclusion The Vida Ativa Melhorando a Saúde Program, in the applied format, was not able to promote lasting beneficial effects on physical activities and nutritional status. The Program is being restructured regarding the extension of the intervention time and its didactic material.

Abstract
This study aimed to evaluate the effectiveness of the VAMOS strategy (Health-Improving Active Life) in improving physical activity (PA), dietary habits, and anthropometric variables of primary health care (PHC) users in Brazil. A randomized controlled community trial was conducted at two units of the Health Academy Program (HAP; a service provided by PHC), which were randomly assigned either to control group (CG) or intervention group (IG). Participants in both groups (CG = 156 and IG = 135) took part in physical activity classes provided by HAP facilities with those in IG also participating in the VAMOS strategy for 12 weeks. This strategy is based on social cognitive theory. The main behavioral constructs addressed were self-efficacy, goal setting, self-monitoring, identification of social support and barriers, and solutions for the identified barriers. Physical activity was measured with accelerometers, and nutritional status was assessed using dietary habits questionnaires and anthropometric measurements. Intention-to-treat analysis revealed that participants in IG increased the daily time of moderate-vigorous PA and the frequency of raw vegetable intake, while the intake of ultra-processed foods was reduced. Weight loss among participants who were classified as overweight/obese at baseline was observed in the intervention group compared to control. These results suggest that the VAMOS strategy was effective in increasing PA, healthy dietary habits, and decreasing weight among PHC users. Therefore, VAMOS could be used as a strategy to strengthen individuals' autonomy regarding healthy choices and improve their overall health.

Abstract
Cordeiro, R, Monteiro, W, Cunha, F, Pescatello, LS, and Farinatti, P. Influence of acute concurrent exercise performed in public fitness facilities on ambulatory blood pressure among older adults in Rio de Janeiro city. J Strength Cond Res 32(10): 2962-2970, 2018-The project "Third-Age Academies'" (TAAs) is a public policy providing supervised physical activities to over 40,000 seniors at open-access facilities (squares etc.) in Rio de Janeiro, Brazil. We investigated whether TAA concurrent exercise circuit induced postexercise hypotension (PEH) in individuals older than 60 years. Blood pressure (BP) was measured by 24-hour ambulatory BP monitoring (ABPM) after counterbalanced CEX and nonexercise (CONT) sessions (n = 16; 66.8 ± 1.4 years; systolic/diastolic BP (SBP/DBP): 132.5 ± 4.3/78.0 ± 2.8 mm Hg). For statistical analyses purposes, groups were divided as exhibiting normal SBP (≤120 mm Hg) or high SBP (>120 mm Hg), based on 24-hour ABPM after CONT. The CEX included 2 aerobic and 9 resistance exercises performed alternately in circuit order (40 minutes at 60-70% heart rate reserve using body mass or fixed loads). 24-hour ambulatory BP monitoring lowered in individuals with high BP (n = 11; medicated = 5) (SBP: -6.5 ± 1.9 mm Hg; mean arterial pressure [MAP]: -4.3 ± 1.5 mm Hg; p < 0.015), particularly within the first 5-6 hours after exercise (SBP: -13.5 ± 2.6 mm Hg; DBP: -9.4 ± 2.2 mm Hg; and MAP: -11.4 ± 1.6 mm Hg, p < 0.05). Significant BP lowering was not detected among participants with normal BP (n = 5; medicated = 4). In conclusion, CEX provoked PEH in older adults with prehypertension to established hypertension. Because of the potential of TAAs to reach large numbers of older adults, our findings are encouraging and should be confirmed in subsequent studies.

Exp Ther Med 2018; 15:2844-2850. [PMID: 29456688 PMCID: PMC5795718 DOI: 10.3892/etm.2018.5733] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2016] [Accepted: 06/29/2017] [Indexed: 12/16/2022] Open
Abstract
The aim of the present study was to measure the expression of microRNA (miRNA)-506-3p in the peripheral blood of patients with hypertension and to determine the biological functions and mechanisms of action of miR-506-3p. A total of 61 patients with primary hypertension were included in the present study. Peripheral blood was collected from all patients, as well as 31 healthy subjects who were included in a control group. The expression of miR-506-3p in peripheral blood was determined by reverse transcription-quantitative polymerase chain reaction. Human umbilical vein endothelial cells (HUVECs) were transfected with miR-506-3p mimics or miR-506-3p inhibitor. The proliferation and migration of HUVECs were determined using cell-counting kit 8 and Transwell assays, respectively. The cell cycle and apoptosis of HUVECs were detected by flow cytometry. The expression of Beclin1 (BECN1) protein, a potential target of miR-506-3p, was measured using western blotting. A dual-luciferase reporter assay was performed to determine the interaction between BECN1 and miR-506-3p. It was demonstrated that miR-506-3p expression in the peripheral blood of patients with patients was upregulated and dependent on the severity of hypertension. miR-506-3p overexpression inhibited the proliferation and migration of HUVECs. In addition, miR-506-3p inhibited the transition from the G1 phase to the S-phase in HUVECs. Overexpression of miR-506-3p promoted the apoptosis of HUVECs. Notably, miR-506-3p downregulated the expression of BECN1 by directly binding to its 3′-untranslated region. The present study demonstrated that miR-506-3p expression is elevated in the peripheral blood of patients with hypertension and is associated with the severity of hypertension. By downregulating BECN1 expression, miR-506-3p aggravates injury in vascular endothelial cells by inhibiting the proliferation and migration of HUVECs, as well as promoting their apoptosis.
