[PMID: 38352804 PMCID: PMC10862017 DOI: 10.1016/j.heliyon.2024.e25715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 01/31/2024] [Accepted: 02/01/2024] [Indexed: 02/16/2024] Open
Abstract
Hypertension is an important risk factor concomitant with cardiovascular disease (CVD) states, which is why we set out to evaluate Californian red worm hydrolysates on antihypertensive activity both in vitro, ex vivo, using rabbit aortic rings and in vivo using hypertensive induced rats. The worms were manually separated, washed with water, purged for 4 h with 4 % sodium bicarbonate, sacrificed with 7 % saline, and finally washed with drinking water. The in vitro antihypertensive capacity was performed by measuring angiotensin-converting enzyme inhibition; for the ex vivo assays, rabbit aorta was used to measure relaxation; for the in vivo assays, rats with induced hypertension were used to perform acute (hypotension) and chronic assays, using captopril as a control in all assays. With respect to angiotensin-converting enzyme (ACE) inhibition, the EC50 value of the worm hydrolysate was found to be 358 ppm; with respect to the analysis in aortic rings, it was found that the mechanisms of action of the hydrolysate are endothelium-dependent, presenting a maximum relaxation of 35 %. With respect to the in vivo assays, the hypotensive test showed that the hydrolysate can reduce blood pressure by up to 32 % in only 2 h, while the chronic analysis showed that the hydrolysate at 150 ppm did not present statistically significant differences with the control (captopril) during the 15 days of analysis. The Red Californian earthworm hydrolysate presents bioactive compounds identified with antihypertensive activities in vitro, ex vivo and in vivo in different isolated and animal models. The study demonstrates the efficacy of the hydrolysate to be used as an alternative in the treatment and prevention of hypertension, and it can be implemented in functional foods or nutraceutical foods. Antihypertensive peptides, particularly those that inhibit angiotensin-converting enzyme (ACE), hold significant importance in medical research, specifically in the context of cardiovascular disease treatment, particularly hypertension. The focus on these peptides and the potential implications of their results in medical research can be summarized through several key points: 1) Mechanisms of Action-Antihypertensive peptides function by inhibiting ACE or renin, crucial enzymes in blood pressure regulation. 2)Alternatives to Synthetic Drugs, 3) Additional Health Benefits, and various other factors.

Abstract
BACKGROUND In Haiti, cardiovascular disease is a leading cause of morbidity and mortality, with congenital and rheumatic heart disease comprising a large portion of disease burden. However, domestic disparities in cardiac care access and their impact on clinical outcomes remain poorly understood. We analyzed population-level sociodemographic variables to predict cardiac care outcomes across the 10 Haitian administrative departments. METHODS This cross-sectional study combined data from a 2016-17 Haitian national survey with aggregate outcomes from the Haiti Cardiac Alliance (HCA) database (n = 1817 patients). Using univariate and multivariable regression analyses, the proportion of HCA patients belonging to each of three clinical categories (active treatment, lost to follow-up, deceased preoperatively) was modeled in relation to six population-level variables selected from national survey data at the level of the administrative department. RESULTS In univariate analysis, higher department rates of childhood growth retardation were associated with a lower proportion of patients in active care (OR = 0.979 [0.969, 0.989], p = 0.002) and a higher proportion of patients lost to follow-up (OR = 1.016 [1.006, 1.026], p = 0.009). In multivariable analysis, the proportion of department patients in active care was inversely associated with qualified prenatal care (OR = 0.980 [0.971, 0.989], p = 0.005), and child growth retardation (OR = 0.977 [0.972, 0.983]), p = 0.00019). Similar multivariable results were obtained for department rates of loss to follow-up (child growth retardation: OR = 1.018 [1.011, 1.025], p = 0.002; time to nearest healthcare facility in an emergency: OR = 1.004 [1.000, 1.008, p = 0.065) and for preoperative mortality (prenatal care: OR = 0.989 [0.981, 0.997], p = 0.037; economic index: OR = 0.996 [0.995, 0.998], p = 0.007; time to nearest healthcare facility in an emergency: OR = 0.992 [0.988, 0.996], p = 0.0046). CONCLUSIONS Population-level survey data on multiple variables predicted domestic disparities in HCA clinical outcomes by region. These findings may help to identify underserved areas in Haiti, where increased cardiac care resources are required to improve health equity. This approach to analyzing clinical outcomes through the lens of population-level survey data may inform future health policies and interventions designed to increase cardiac care access in Haiti and other low-income countries.

Abstract
BACKGROUND CKD is a major cause of morbidity and mortality in lower-income countries. However, population-based studies characterizing the epidemiology of CKD in these settings are lacking. The study objective was to describe the epidemiology of CKD in a population-based cohort in urban Haiti, including estimates of the prevalence by CKD stage, the magnitude of associated factors with CKD, and the proportion on guideline-recommended treatment. METHODS We assessed the prevalence of CKD and associated risk factors in the population-based Haiti Cardiovascular Disease Cohort. We analyzed cross-sectional data from 2424 adults who completed a clinical examination, risk factor surveys, and laboratory measurements for serum creatinine, urinary albumin, and urinary creatinine. We compared our results with US estimates from the National Health and Nutrition Examination Survey. CKD was defined as either a reduced eGFR <60 ml/min per 1.73 m 2 or urinary albumin-to-creatinine ratio ≥30 mg/g according to the Kidney Disease Improving Global Outcomes guidelines. Multivariable logistic regression identified associated factors with CKD. RESULTS The mean age was 42 years, 57% of participants were female, and 69% lived in extreme poverty on ≤1 US dollar per day. The age-standardized prevalence of CKD was 14% (95% confidence interval [CI], 12% to 15%). The age-standardized prevalence of reduced eGFR and elevated urinary albumin-to-creatinine ratio was 3% (95% CI, 2% to 4%) and 11% (95% CI, 10% to 13%), respectively. Diabetes (adjusted odds ratio, 4.1; 95% CI, 2.7 to 6.2) and hypertension (adjusted odds ratio, 2.9; 95% CI, 2.0 to 4.2) were significantly associated with CKD. Only 12% of participants with CKD and albuminuria were on guideline-recommended agents, such as angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers. CONCLUSIONS In a large population-based cohort of Haitian adults, CKD was highly associated with both diabetes and hypertension. The proportion of participants with CKD on treatment was low, underscoring the need for strengthening clinical management and nephrology care health infrastructure in Haiti.

Bioactive protein hydrolysates obtained from amaranth by fermentation with lactic acid bacteria and Bacillus species. Heliyon 2023; 9:e13491. [PMID: 36846651 PMCID: PMC9950839 DOI: 10.1016/j.heliyon.2023.e13491] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 01/04/2023] [Accepted: 01/31/2023] [Indexed: 02/05/2023] Open
Abstract
Protein hydrolysates are a promising source of bioactive peptides. One strategy by which they can be obtained is fermentation. This method uses the proteolytic system of microorganisms to hydrolyze the parental protein. Fermentation is a little-explored method for obtaining protein hydrolysates from amaranth. Different strains of lactic acid bacteria (LAB) and Bacillus species isolated from goat milk, broccoli, aguamiel, and amaranth flour were used in this work. First, the total protein degradation (%TPD) of amaranth demonstrated by the strains was determined. The results ranged from 0 to 95.95%, the strains that produced a higher %TPD were selected. These strains were identified by molecular biology and were found to correspond to the genera Enterococcus, Lactobacillus, Bacillus, and Leuconostoc. Fermentation was carried out with amaranth flour and the selected strains. After this process, water/salt extracts (WSE) containing the released protein hydrolysates were obtained from amaranth doughs. The peptide concentration was measured by the OPA method. The antioxidant, antihypertensive and antimicrobial activity of the WSE was evaluated. In the FRAP test, the best WSE was LR9 with a concentration of 1.99 μMTE/L ± 0.07. In ABTS, 18C6 obtained the highest concentration with 19.18 μMTE/L ± 0.96. In the DPPH test, there was no significant difference. In terms of antihypertensive activity, inhibition percentages ranging from 0 to 80.65% were obtained. Some WSE were found to have antimicrobial properties against Salmonella enterica and Listeria monocytogenes. Fermentation of amaranth with LAB and Bacillus spp. allowed the release of protein hydrolysates with antioxidant, antihypertensive, and antimicrobial activity.

Cereals as a Source of Bioactive Compounds with Anti-Hypertensive Activity and Their Intake in Times of COVID-19. Foods 2022; 11:3231. [PMID: 37430980 PMCID: PMC9601750 DOI: 10.3390/foods11203231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Revised: 10/08/2022] [Accepted: 10/11/2022] [Indexed: 11/16/2022] Open
Abstract
Cereals have phytochemical compounds that can diminish the incidence of chronic diseases such as hypertension. The angiotensin-converting enzyme 2 (ACE2) participates in the modulation of blood pressure and is the principal receptor of the virus SARS-CoV-2. The inhibitors of the angiotensin-converting enzyme (ACE) and the block receptors of angiotensin II regulate the expression of ACE2; thus, they could be useful in the treatment of patients infected with SARS-CoV-2. The inferior peptides from 1 to 3 kDa and the hydrophobic amino acids are the best candidates to inhibit ACE, and these compounds are present in rice, corn, wheat, oats, sorghum, and barley. In addition, the vitamins C and E, phenolic acids, and flavonoids present in cereals show a reduction in the oxidative stress involved in the pathogenesis of hypertension. The influence of ACE on hypertension and COVID-19 has turned into a primary point of control and treatment from the nutritional perspective. The objective of this work was to describe the inhibitory effect of the angiotensin-converting enzyme that the bioactive compounds present in cereals possess in order to lower blood pressure and how their consumption could be associated with reducing the virulence of COVID-19.

Abstract
Shellfish are diverse, widely distributed organisms that are a rich source of biological resources. Polysaccharides are an important components in shellfish, hence a great deal of attention has been directed at isolation and characterization of shellfish polysaccharides because of their numerous health benefits. Differences in shellfish species, habits, and environment result in the diversity of the structure and composition of polysaccharides. Thus, shellfish polysaccharides possess special biological activities. Studies have shown that shellfish polysaccharides exert biological activities, including antioxidant, antitumor, immune-regulation, hypolipidemic, antihypertensive, and antihyperglycemic effects, and are widely used in cosmetics, health products, and medicine. This review spotlights the extraction and purification methods of shellfish polysaccharides and analyses their structures, biological activities and conformational relationships; discusses the regulatory mechanism of shellfish polysaccharides on hyperlipidemia, hypertension, and hyperglycemia caused by lipid metabolism disorders; and summarizes its alleviation of lipid metabolism-related diseases. This review provides a reference for the in-depth development and utilization of shellfish polysaccharides as a functional food to regulate lipid metabolism-related diseases. To achieve high value utilization of marine shellfish resources while actively promoting the development of marine biological industry and health industry.

Abstract
AIM AND OBJECTIVE To explore what is known about knowledge, attitudes and beliefs that influence hand hygiene practices in in low- and middle-income Caribbean and Latin American countries. BACKGROUND With the emergence of infectious diseases such as the recent COVID-19 pandemic, handwashing is key to preventing communicable diseases as they disproportionately affect populations in low-income countries. While hand hygiene is known to be the single most effective method for avoiding the transmission of infection, little is known about the beliefs and practices of individuals in these regions. METHODS Following PRISMA 2020 Checklist, an integrative review of studies published from 2008-2020 was conducted (Preferred Reporting Items for Systematic Reviews and Meta-analyses). Whittemore and Knafl's method was used to review the literature. Six databases were searched, and the Johns Hopkins Evidence Based Rating Scale was used for study appraisal. RESULTS The review yielded 18 studies conducted across Latin America. Poor handwashing practices are influenced by various factors including inadequate education and training, cultural beliefs, lack of resources and substandard government regulations. Communicable diseases and other diarrheal illnesses were highly prevalent, especially after a major disease outbreak. CONCLUSION Future post-disaster campaigns aimed at improving hand hygiene and handwashing practices should focus on beliefs and attitudes to affect behaviour change since there was a higher disease susceptibility during those times. Barriers to proper hand hygiene include false attitudes such as, washing hands only after touching bodily fluids/patient contact or not washing hands at all after open defecation. RELEVANCE TO CLINICAL PRACTICE Researchers working with populations in Latin America and the Caribbean should partner with local community health workers to improve compliance to recommended hand hygiene practices.

Abstract
Cardiovascular disease (CVD) is the number one cause of death in low-income countries including Haiti, with hypertension (HTN) being the leading risk factor. This study aims to identify gaps in the HTN continuum of screening, diagnosis, treatment, and blood pressure (BP) control. Sociodemographic and clinical data were collected from a population-based sample of adults ≥18 years in Port-au-Prince (PAP) from March 2019 to April 2021. HTN was defined as systolic BP ≥ 140 mmHg, diastolic BP ≥ 90 mmHg, or use of antihypertensive medication. Screening was defined as ever having had a BP measurement; diagnosis as previously being informed of a HTN diagnosis; treatment as having taken antihypertensives in the past 2 weeks; and controlled as taking antihypertensives and having BP < 140/90 mmHg. Factors associated with attaining each step in the continuum were assessed using Poisson multivariable regressions. Among 2737 participants, 810 (29% age-standardized) had HTN, of whom 97% had been screened, 72% diagnosed, 45% treated, and 13% controlled. There were no significant differences across age groups or sex. Obesity (BMI ≥ 30) was a significant factor associated with receiving treatment compared to normal weight (BMI < 25), with a prevalence ratio (PR) of 1.5 (95% CI 1.1-2.0). Having secondary or higher education was associated with higher likelihood of controlled BP (PR 1.9 [95% CI 1.1-3.3]). In this urban Haitian population, the greatest gaps in HTN care are treatment and control. Targeted interventions are needed to improve these steps, including broader access to affordable treatment, timely distribution of medications, and patient adherence to HTN medication.

Patil PJ, Usman M, Zhang C, Mehmood A, Zhou M, Teng C, Li X. An updated review on food-derived bioactive peptides: Focus on the regulatory requirements, safety, and bioavailability. Compr Rev Food Sci Food Saf 2022; 21:1732-1776. [PMID: 35142435 DOI: 10.1111/1541-4337.12911] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2021] [Revised: 12/07/2021] [Accepted: 12/22/2021] [Indexed: 02/06/2023]
Abstract
Food-derived bioactive peptides (BAPs) are recently utilized as functional food raw materials owing to their potential health benefits. Although there is a huge amount of scientific research about BAPs' identification, purification, characterization, and physiological functions, and subsequently, many BAPs have been marketed, there is a paucity of review on the regulatory requirements, bioavailability, and safety of BAPs. Thus, this review focuses on the toxic peptides that could arise from their primary proteins throughout protein extraction, protein pretreatment, and BAPs' formulation. Also, the influences of BAPs' length and administration dosage on safety are summarized. Lastly, the challenges and possibilities in BAPs' bioavailability and regulatory requirements in different countries were also presented. Results revealed that the human studies of BAPs are essential for approvals as healthy food and to prevent the consumers from misinformation and false promises. The BAPs that escape the gastrointestinal tract epithelium and move to the stomach are considered good peptides and get circulated into the blood using different pathways. In addition, the hydrophobicity, net charge, molecular size, length, amino acids composition/sequences, and structural characteristics of BAPs are critical for bioavailability, and appropriate food-grade carriers can enhance it. The abovementioned features are also vital to optimize the solubility, water holding capacity, emulsifying ability, and foaming property of BAPs in food products. In the case of safety, the possible allergenic and toxic peptides often exhibit physiological functions and could be produced during the hydrolysis of food proteins. It was also noted that the production of iso-peptides bonds and undesirable Maillard reaction might occur during protein extraction, sample pretreatments, and peptide synthesis.

Photosynthetic microorganisms and their bioactive molecules as new product to healing wounds. Appl Microbiol Biotechnol 2022; 106:497-504. [PMID: 34985569 DOI: 10.1007/s00253-021-11745-6] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Revised: 12/13/2021] [Accepted: 12/14/2021] [Indexed: 12/19/2022]
Abstract
Wounds are a public health problem due to long periods required to repair damaged skin, risk of infection, and amputations. Thus, there is a need to obtain new therapeutic agents with less side effects, more effective oxygen delivery, and increased epithelial cell migration. Photosynthetic microorganisms, such as microalgae and cyanobacteria, may be used as a source of biomolecules for the treatment of different injuries. The aim of this review article focuses on healing potential using phytoconstituents from photosynthetic microorganisms. Cyanophyte Spirulina and Chlorophyte Chlorella are more promising due to steroids, triterpenes, carbohydrates, phenols, and proteins such as lectins and phycocyanin. However, there are few reports about identification and specific function of these molecules on the skin. In other microalgae and cyanobacteria genus, high contents of pigments such as β-carotene, chlorophyll a, allophycocyanin, and hydroxypheophytin were detected, but their effects on phases of wound healing is absent yet. The development of new topical drugs from photosynthetic microorganisms could be a potential alternative to maximize healing. KEY POINTS: • Conventional treatment to skin injuries has limitations. • Proteins, terpenes, and phenols increase collagen deposition and re-epithelialization. • Microalgae and cyanobacteria may be used as a source of biomolecules to wound healing.

J Clin Nurs 2021; 30:2960-2967. [PMID: 33872425 DOI: 10.1111/jocn.15803] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Revised: 02/22/2021] [Accepted: 03/23/2021] [Indexed: 12/01/2022]
Abstract
AIMS AND OBJECTIVES To examine the feasibility of a culturally tailored education programme for Haitian immigrants diagnosed with hypertension. BACKGROUND Hypertension is a major public health problem, impacting more than 26% of the global population. The overall prevalence of hypertension is 45.4% in the United States with nearly 80,000 deaths due to hypertension in 2015. African Americans and other Black populations living in the U.S. are disproportionally affected by hypertension. DESIGN Pre-test and post-test feasibility study. METHODS A convenience sample of forty-four participants who identified as Haitian immigrants was enrolled in this evidence-based education programme. The intervention included culturally tailored education focused on improving knowledge, medication adherence and blood pressure. Outcomes were measured using the Hill-Bone Medication Adherence Scale and Hypertension Knowledge Test. The SQUIRE 2.0 guidelines were used for reporting outcomes. RESULTS Of the participants that completed the study (N=42), the mean age was 61.95 (± 9.75) years and 59% were female. Baseline systolic and diastolic blood pressures were 143 (±18.15) and 85 (±7.23), respectively. Six weeks after the intervention, there was a significant decrease in mean systolic, 126 (±12.07) and diastolic 78.50 (± 7.23) blood pressures. An increase in medication adherence and hypertension knowledge was also noted at the six-week follow-up period. CONCLUSION The feasibility of healthcare provider implementation of a culturally tailored intervention to manage hypertension has been demonstrated. However, future research is warranted to gain a more in-depth understanding of how to approach hypertension management among Haitians and other Black immigrant communities. RELEVANCE TO CLINICAL PRACTICE Advanced practice nurses are uniquely qualified to implement evidence-based programmes that improve patient knowledge and adherence to hypertension management. Through tailoring and adopting an evidence-based methods for educating patients about medication adherence and adequate blood pressure management, there is a potential to see improvements in patient outcomes.

Abstract
Hypertension is a non-communicable disease characterized by elevated blood pressure, and a prominent metabolic syndrome of modern age. Food-borne bioactive peptides have shown considerable potencies as suitable therapeutic agents for hypertension. The peptide inhibition of the angiotensin I-converting enzyme (ACE) from its default biochemical conversion of Ang I to Ang II has been studied and more relatively adopted in several studies. This review offers an examination of the isolation of concomitant proteins in foods, their hydrolysis into peptides and the biofunctionality checks of those peptides based on their anti-hypertensive potentialities. Furthermore, critical but concise details about methodologies and analytical techniques used in the purification of such peptides are discussed. This review is a beneficial literature supplement for scholars and provides functional awareness material for the food-aligned alternative therapy for hypertension. In addition, it points researchers in the direction of adopting food materials and associated by-products as natural sources for the isolation biologically active peptides.
