Adherence to Treatment in Hypertension

Cardioprotective Effects of Solidago microglossa DC. in Nicotine-Treated Hypertensive Rats

Solidago microglossa DC. (Asteraceae), "arnica brasileira," is a Brazilian species popularly used to treat hypertension or renal ailments. This study investigated the cardioprotective effects of standardized S. microglossa extract (EESM) in nicotine-treated spontaneously hypertensive rats (SHRs). Moreover, the molecular mechanisms involved in the cardiovascular effects were also investigated. The acute toxicity was evaluated in female Wistar rats. Afterwards, six-month-old male spontaneously hypertensive rats received the EESM (14, 28, and 56 mg/kg), hydrochlorothiazide (25 mg/kg), and vehicle (filtered water; 0.1 mL/100 g) once daily for 28 days. All treatments were associated with 1.8 mg/kg of nicotine. At the end of the experimental period, the renal function, electrocardiographic profile, blood pressure, ventricular function, biochemical parameter, and mesenteric vascular bed reactivity were evaluated. Relative organ weights and cardiac morphometry were also investigated. Nicotine treatment in 6-month-old SHRs induced a significant reduction in renal function, with reduced urinary volume and lower renal elimination of sodium and creatinine. In addition, serum markers of the redox state and blood pressure levels remained significantly elevated, contributing to changes in vascular reactivity and left ventricular hypertrophy associated with reduced ventricular function. After 28 days of treatment, we found that the highest dose of EESM could mitigate all renal and cardiovascular changes developed by the nicotine-treated hypertensive rats. This study presented EESM as a possible cardioprotective drug that prevents cardiovascular dysfunctions in nicotine-treated hypertensive rats. Our data suggest EESM as a potential adjuvant therapy when cardioprotective effects are required.

[Quality of life and therapeutic adherence in a hypertension program]

OBJECTIVE

To determine the association between treatment adherence and health-related quality of life.

METHODS AND MATERIALS

A cross-sectional investigation was performed in an arterial hypertension program of a general hospital. The Spanish version of the Short Form-36 Health Survey and the Spanish version of the Morisky-Green test. The scores of the subscales and Physical Component (PCS) and Mental Component (MCS) summaries of the SF-36 survey were obtained, then the respective bivariate and multivariate analyzes (Poisson regression) were executed.

RESULTS

39% of patients had therapeutic adherence. All the dimensions of the SF-36 survey presented a statistical association with adherence to antihypertensive treatment. Poisson regression was executed to identify the independent variables associated with obtaining a score higher than 50 in the PCS [presence of comorbidity (risk factor), work status, and therapeutic adherence (protective factor)] and MCS (therapeutic adherence as a protective factor).

CONCLUSIONS

Therapeutic adherence, work status, and absence of comorbidity were associated with a better health-related quality of life.

Test performance of self-report adherence tools in patients with hypertension: A systematic review and a meta-analysis

WHAT IS KNOWN AND OBJECTIVES

Adherence has proved to have a positive influence on achieving plausible treatment outcomes. Self-report questionnaires are widely used in evaluating adherence, creating thus a high-powered research field. This review aims to provide an update of scales used in hypertension, which are compared and analysed against reliability and validity.

METHODS

PubMed, Web of Science and Cochrane Library were searched in May 2022 to identify studies. We extracted the study characteristics and evaluated their quality. A random-effects model with subgroup analysis was used to calculate estimates and heterogeneity parameters as well as regressions, funnel and forest plots. A bivariate model was selected to conduct validity analyses and draw receiver operating characteristic (ROC) curves.

RESULTS AND DISCUSSION

Fifty-five articles were identified and classified into 22 different reliable and validated tools. Pooled analyses predicted an overall good Cronbach's alpha of 0.76 (95%CI:0.67-0.83), a good ICC of 0.8 (95%CI:0.72-0.86) and an excellent correlation coefficient of 0.91 (95%CI:0.86-0.95), which all showed high heterogeneity and slight detection of asymmetry. Regression analyses showed that only time and the number of items/scale type influenced significantly retest and alpha, respectively. Overall validity showed acceptable sensitivity of 0.65 (95%CI:0.53-0.75) and specificity of 0.57 (95%CI:0.47-0.67) with a good Area Under Curve (AUC) of 0.637. Upon comparison, four tools showed superiority over Morisky's scale.

WHAT IS NEW AND CONCLUSION

Adherence is a multi-dimensional phenomenon, which deems scales to be highly variable or complex; thus, complicating the selection process. Adherence to Refills and Medications Scale (ARMS) is the most promising free non-inferior alternative to Morisky, the most used scale.

Health literacy and adherence to the pharmacological treatment by people with arterial hypertension

OBJECTIVE

To analyze the association between health literacy and the adherence to the pharmacological treatment of Brazilians with arterial hypertension.

METHODS

Cross-sectional study with 234 participants who responded an on-line sociodemographic and clinical characterization questionnaire, in addition to evaluation of health literacy and of the adherence to their pharmacological treatment. Data were analyzed using descriptive statistics and difference and correlation tests.

RESULTS

People with post-graduation, who were actively working and did not smoke, had better health literacy results. Elders and those who were retired or lived on government subsidies adhered better to the medication treatment. There was a correlation between the numerical dimension (rs=0.189; p=0.004) and the global health literacy result (r2=0.170; p=0.009) with the adherence.

CONCLUSIONS

A better numerical and global understanding of health literacy was associated with better adherence to arterial hypertension medication treatment.

High adherence and its influencing factors on multiple micronutrient powders (MNPs)

Adherence to home fortification of foods with multiple micronutrient powders (MNPs) is an essential indicator of effective implementation of MNP programmes. A meta‐analysis was conducted to evaluate the high adherence rate (HAR) to MNPs and further investigate the factors that influence HAR. We searched PubMed, Web of Science, Embase, CAB Abstracts, MEDLINE (OVID), Cochrane Library, China National Knowledge Infrastructure, Wanfang and VP, from the date of database inception to 9 November 2020. We included peer‐reviewed observational studies that investigated adherence to MNPs. Data on the HAR to MNPs and influencing factors on HAR were extracted and then pooled together. A total of 10 studies were included. The pooled HAR to MNPs was 63.28% (51.12%–74.64%). Among HARs, rates were higher in middle‐income countries (65.21%) than low‐income countries (55.23%). Parental age over 30 years (maternal age OR = 1.25, 95% CI: 1.08–1.44; paternal age OR = 1.17, 95% CI: 1.04–1.32), children aged 18–36 months (OR = 1.45, 95% CI: 1.12–1.88), maternal educational attainment of college or above (OR = 1.38, 95% CI:1.10–1.73), caregiver with the perception that other mothers use MNPs (OR = 1.52, 95% CI:1.19–1.95), caregiver being aware of the importance of iron (OR = 1.42, 95% CI: 1.18–1.71), caregiver having correct knowledge of MNPs (OR = 1.36, 95% CI:1.19–1.57) and caregiver reporting children have no side effects from MNPs (OR = 2.77, 95% CI: 2.46–3.11) were contributing factors to high adherence to MNPs. The overall HAR to MNPs was relatively low; hence, effective and trusted communication channels need to be established, along with more thorough dissemination of the knowledge of MNPs to caregivers, to improve MNPs adherence rates, especially in low‐income countries.

[Interactions between drug treatment adherence, blood pressure targets, and depression in hypertensive individuals receiving care in the Family Health Strategy]

The study analyzes interactions between drug treatment adherence, blood pressure targets, and depression in a probabilistic sample of hypertensive individuals treated in the Family Health Strategy in Governador Valadares, Minas Gerais State, Brazil. This is a cross-sectional study with 641 hypertensive individuals 40 years or older, residing in the urban area of Governador Valadares. Structured scripts were used to collect data in home interviews, with a focus on the following indicators: Medication Assessment Questionnaire (MAQ), Beck Depression Inventory (BDI), and blood pressure measurement. Due to the simultaneity of the target events (depression, blood pressure target, and adherence), we applied a system of recursive and simultaneous nonlinear equations. The results suggest that the odds of meeting the blood pressure target increase significantly with adherence to treatment; they also suggest that individuals that meet the blood pressure target show 2.6 higher odds of treatment adherence. Adherence has a protective effect against depression: individuals with minimal adherence show 8.4 higher odds of developing depressive symptoms when compared to those with maximum adherence. Drug treatment adherence is related simultaneously to blood pressure control and lower levels of depression. Promoting drug treatment adherence is essential for ensuring that individuals remain normotensive, with the potential for reducing levels of depression. These positive externalities can reduce pressure on the health system, with simultaneous gains in quality of life for hypertensive individuals.

Apprehensions about Excessive Belief in Digital Therapeutics: Points of Concern Excluding Merits

Digital therapeutics (DTx), like drugs or medical devices, 1) must prove their effectiveness and safety through clinical trials; 2) are provided to patients through prescriptions from doctors; and 3) may require the approval of regulatory agencies, though this might not be mandatory. Although DTx will play an important role in the medical field in the near future, some merits of DTx have been exaggerated at this crucial juncture. In the medical field, where safety and effectiveness are important, merely reducing the development time and costs of DTx is not advantageous. The adverse effects of DTx are not yet well-known, and will be identified eventually, with the passage of time. DTx is beneficial for the collection and analysis of real-world data (RWD); however, they require new and distinct work to collect and analyze high-quality RWD. Naturally, whether this is possible must be independently ascertained through scientific methods. Depending on the type of disease, it is not recommended that DTx be prescribed, even if the patient rejects conventional treatment. Prescription of conventional pharmacotherapy is often necessary, and if the prescription of DTx is inadequate, the critical time for initial treatment may be missed. There is no basis for continuing DTx use by patients. Rather, the rate of continuity of DTx use is extremely low. While many conventional pharmacotherapies have undergone numerous verification and safety tests over a long time, barriers to the application of DTx in the medical field are lower than those for conventional pharmacotherapies. Considering these reasons, except for certain special cases, an approach to DTx is needed that complements the prescription of conventional pharmacotherapy by the medical staff. When DTx are prescribed by doctors who clearly know their advantages and disadvantages, the doctors' expertise may undergo further refinement, and the quality of medical care is expected to improve.

Therapeutic Compliance of Patients with Arterial Hypertension in Primary Care

Background and Objectives: Arterial hypertension remains an important cause of cardiovascular morbidity and mortality, despite all the progress made in the methods of diagnosis, monitoring of target organs’ damage and treatment. The main cause of the increased prevalence of uncontrolled blood pressure values is the low compliance to antihypertensive treatment. The objective of our study was to assess the compliance to the treatment of patients diagnosed with arterial hypertension and monitored in a primary care office. Materials and Methods: The cross-sectional, retrospective study included 129 patients, 65.89% (85) women, previously diagnosed with arterial hypertension. Data from the medical files were analyzed, as well as the patients’ answers to a survey of 18 questions regarding arterial hypertension, comorbidities, complications, treatment and awareness of the condition. Results: The study included 129 patients, with a mean age of 66 ± 8 years. The majority of patients were overweight, 55.81% (72 patients), and 10.85% (14 patients) had grade I obesity. Most of the patients, 55.81% (72 patients) were diagnosed with grade III hypertension, while 37.98% (49 patients) were diagnosed with grade II hypertension and 6.2% (8 patients) with grade I hypertension. One third of the surveyed patients answered that they follow the recommendations of a low-sodium diet, 21.7% are adherent to treatment, but 56% think that the total cost of the medication is an impediment for their compliance to treatment. The majority, 82.17% (106 patients), of respondents had an affirmative answer to the questions: ‘Do you think it would be easier to take one pill instead of 2, 3 or 4 pills?’ Conclusion: The increased compliance to the antihypertensive treatment and control of blood pressure values are associated with the degree of awareness of arterial hypertension and the consequences if left untreated, emphasizing the role of the general practitioner in counseling for secondary prevention.

Elderly patients with hypertension self-perceived of aging status and compliance with medical behaviour

At present, it is rare for studies to be performed on the impact of self-perceptions of aging on the compliance behaviour of elderly people.The present study explored the relationship between self-perceived of aging level and compliance behavior among asample of elderly Chinese hypertension patients. Participants (N=1129) were recruited from four community health service centres and two township hospitals in Suzhou. Self-perceptions of aging represent an independent risk factor for compliance behaviour in elderly patients with hypertension. Self-perceptions of aging had acute/chronic timeliness (OR=0.793), periodic timeliness (OR=1.439), emotional representation (OR=0.735), positive results (OR=1.322), and identity latitude (OR=0.995). Gender (OR=1.390), age (OR=1.982), residence (OR=7.037), hypertension grade (OR=0.598), sleep (OR=1.709), number of hospital admissions in a year (OR=2.757), number of daily uses of antihypertensive drugs (OR=0.338), and frequency of blood pressure measurement (OR=0.387) were independent factors affecting the compliance behavior of elderly patients with hypertension. The results suggest that self-perceptions of aging can be used as an indirect index to monitor the compliance behaviour of the elderly. In the future medical staff should combine the characteristics of the elderly patients with hypertension, which would help them to establish a positive self-perception of aging, thus improving their compliance behaviour, and the levels of health and literacy.

Exploring a New Natural Treating Agent for Primary Hypertension: Recent Findings and Forthcoming Perspectives

Primary hypertension describes abnormally-high systolic/diastolic blood pressure in a resting condition caused by various genetic or environmental risk factors. Remarkably, severe complications, such as ischemic cardiovascular disease, stroke, and chronic renal disease have led to primary hypertension becoming a huge burden for almost one-third of the total population. Medication is the major regimen for treating primary hypertension; however, recent medications may have adverse effects that attenuate energy levels. Hence, the search for new hypotensive agents from folk or traditional medicine may be fruitful in the discovery and development of new drugs. This review assembles recent findings for natural antihypertensive agents, extracts, or decoctions published in PubMed, and provides insights into the search for new hypotensive compounds based on blood-pressure regulating mechanisms, including the renin-angiotensin-aldosterone system and the sympathetic/adrenergic receptor/calcium channel system.
