Abstract
The prevalence of cardiovascular diseases continues to be a challenge for global health, necessitating innovative solutions. The potential of high-density lipoprotein (HDL) mimetic nanotherapeutics in the context of cardiovascular disease and the intricate mechanisms underlying the interactions between monocyte-derived cells and HDL mimetic showing their impact on inflammation, cellular lipid metabolism, and the progression of atherosclerotic plaque. Preclinical studies have demonstrated that HDL mimetic nanotherapeutics can regulate monocyte recruitment and macrophage polarization towards an anti-inflammatory phenotype, suggesting their potential to impede the progression of atherosclerosis. The challenges and opportunities associated with the clinical application of HDL mimetic nanotherapeutics, emphasize the need for additional research to gain a better understanding of the precise molecular pathways and long-term effects of these nanotherapeutics on monocytes and macrophages to maximize their therapeutic efficacy. Furthermore, the use of nanotechnology in the treatment of cardiovascular diseases highlights the potential of nanoparticles for targeted treatments. Moreover, the concept of theranostics combines therapy and diagnosis to create a selective platform for the conversion of traditional therapeutic medications into specialized and customized treatments. The multifaceted contributions of HDL to cardiovascular and metabolic health via highlight its potential to improve plaque stability and avert atherosclerosis-related problems. There is a need for further research to maximize the therapeutic efficacy of HDL mimetic nanotherapeutics and to develop targeted treatment approaches to prevent atherosclerosis. This review provides a comprehensive overview of the potential of nanotherapeutics in the treatment of cardiovascular diseases, emphasizing the need for innovative solutions to address the challenges posed by cardiovascular diseases.

Phytother Res 2024; 38:2560-2571. [PMID: 38462779 DOI: 10.1002/ptr.8174] [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: 07/05/2023] [Revised: 02/08/2024] [Accepted: 02/13/2024] [Indexed: 03/12/2024]
Abstract
The cardioprotective activity of hesperidin has been well demonstrated in several clinical studies. Also, there is a meta-analysis published on this topic in 2019. However, considering the recently published clinical studies, there is a scope for performing a systematic review and meta-analysis of hesperidin to determine its beneficial effect in alleviating alterations in cardiovascular parameters. In this study, the literature search was performed using online databases such as PubMed and Google Scholar till April 2023 involving randomized controlled studies conducted on hesperidin against various cardiovascular disorders including metabolic disorders in healthy/diseased individuals compared to the placebo/control. Based on the inclusion and exclusion criteria, nine clinical studies involving 2414 subjects were included. The meta-analysis revealed that hesperidin has significantly reduced the low-density lipoprotein (LDL) (IV: -0.55 (-0.94 to -0.16) at 95% CI, p = 0.005, I2 = 70%), total cholesterol (TC) (IV: -61 (-0.82 to -0.41) at 95% CI, p < 0.00001, I2 = 69%), and triglycerides (TG) (IV: -0.21 (-0.40 to -0.02) at 95% CI, p = 0.03, I2 = 12%). However, there were no statistically significant changes in the systolic blood pressure (IV: -0.29 (-2.21 to 1.63) at 95% CI, p = 0.77, I2 = 60%), diastolic blood pressure (IV: 0.79 (-0.74 to 2.31) at 95% CI, p = 0.31, I2 = 49%), and high-density lipoprotein (IV: 0.04 (-0.25 to 0.34) at 95% CI, p = 0.78, I2 = 56%) in the hesperidin treatment compared to the placebo/control. In conclusion, the outcomes of this meta-analysis suggest that hesperidin administration could benefit patients with CVD by reducing LDL, TC, and TG. Further high-quality studies are needed to firmly establish the clinical efficacy of hesperidin for its benefits in treating cardiovascular conditions.

Comparison of low-density lipoprotein cholesterol/high-density lipoprotein cholesterol and total cholesterol/high-density lipoprotein cholesterol for the prediction of thin-cap fibroatheroma determined by intravascular optical coherence tomography. J Geriatr Cardiol 2020; 17:666-673. [PMID: 33343645 PMCID: PMC7729182 DOI: 10.11909/j.issn.1671-5411.2020.11.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 10/20/2020] [Accepted: 11/05/2020] [Indexed: 04/24/2023] Open
Abstract
BACKGROUND The correlation among the ratios of low-density lipoprotein cholesterol/high-density lipoprotein cholesterol (LDL-C/ HDL-C), total cholesterol/high-density lipoprotein cholesterol (TC/HDL-C) and thin-cap fibroatheroma has not yet been established. METHODS It was a single center, retrospective observational study. In total, we recruited 421 patients (82.4% men; mean age 65.73 ± 10.44 years) with one culprit vessel which determined by intravascular optical coherence tomography (OCT). The thinnest-capped fibroatheroma (TCFA) group was defined as lipid contents in > 2 quadrants, with the thinnest fibrous cap measuring less than 65 μm. Univariate and multivariate logistic regression were carried out to explore the relationship between lipoprotein ratios, TCFA and other characteristics of plaque. To compare different ratios, the area under curve (AUC) of receiver-operating characteristic (ROC) curve was assessed. RESULTS OCT was performed in 421 patients (TCFA group (n = 109), non-TCFA group (n = 312)). LDL-C/HDL-C in the TCFA group was significantly higher than in the non-TCFA group (2.95 ± 1.20 vs. 2.43 ± 0.92, P < 0.05), as was TC/LDL in TCFA and non-TCFA group (4.57 ± 1.58 vs. 4.04 ± 1.13, P < 0.05). Both LDL-C/HDL-C (OR: 1.002 (1.002-1.003), P < 0.05) and TC/HDL-C (OR: 1.001 (1.001-1.004), P < 0.05) were considered independent factors for the prediction of TCFA according to the logistic regression. Based on the AUC comparison, LDL-C/ HDL-C and TC/HDL-C had no significant difference statistically (LDL-C/HDL-C AUC: 0.63; TC/HDL-C AUC: 0.61; P = 0.10) for the prediction of TCFA. CONCLUSIONS LDL-C/HDL-C and TC/HDL-C could be the independent factors for predicting the presence of TCFA, indicating coronary plaque vulnerability in CAD patients. Moreover, TC/HDL-C also showed a comparative performance for the prediction of TCFA as LDL-C/HDL-C.

Abstract
Background Recently, developing countries have shown a dramatic increase in non-communicable diseases (NCDs). The burden of NCDs in South Africa has increased over the past years resulting in an estimated 37% of all- cause mortality and 16% of disability-adjusted life years. Currently, diabetes mellitus (DM) and hypertension (HTN) are the two most prevalent NCDs associated with the rapid increase in mortality. Objective To demonstrate the socio-demographic and modifiable risk factors of diabetes mellitus (DM) and hypertension (HTN) among South African adults. Methods A cross-sectional analytical study was conducted in the Cecilia Makiwane Hospital serving the residents of Mdantsane. Relevant socio-demographic data, anthropometric measurements, triplicate blood pressure, fasting blood glucose and lipogram analysis were obtained from 265 outpatients. Results Multivariate anlysis shows that; salt intake, smoking, elevated triglycerides and decreased high-density lipoprotein levels were significantly associated with DM with adjusted odds ratio of 0.18 (p=0.002), 0.26 (p=0.048), 2.19 (p=0.006) and 0.38 (p=0.001), respectively. Overweight and obesity were significantly associated with hypertension with odds ratio of 0.03 (p=0.01) and 0.06 (p=0.006), respectively. Conclusion The burden of DM and HTN on society can be drastically reduced with simple lifestyle changes, development of preventative strategies, large-scale screening and better disease management in South Africa.

[DOI: 10.2174/1570161116666180209112351] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2018] [Revised: 06/14/2018] [Accepted: 06/14/2018] [Indexed: 02/07/2023]
Abstract
Over the last 3 decades, hypolipidaemic treatment has significantly reduced both Cardiovascular
(CV) risk and events, with statins being the cornerstone of this achievement. Nevertheless, residual
CV risk and unmet goals in hypolipidaemic treatment make novel options necessary. Recently marketed
monoclonal antibodies against proprotein convertase subtilisin/kexin type 9 (PCSK9) have shown
the way towards innovation, while other ways of PCSK9 inhibition like small interfering RNA (Inclisiran)
are already being tested. Other effective and well tolerated drugs affect known paths of lipid
synthesis and metabolism, such as bempedoic acid blocking acetyl-coenzyme A synthesis at a different
level than statins, pemafibrate selectively acting on peroxisome proliferator-activated receptor (PPAR)-
alpha receptors and oligonucleotides against apolipoprotein (a). Additionally, other novel hypolipidaemic
drugs are in early phase clinical trials, such as the inhibitors of apolipoprotein C-III, which is located
on triglyceride (TG)-rich lipoproteins, or the inhibitors of angiopoietin-like 3 (ANGPTL3), which
plays a key role in lipid metabolism, aiming to beneficial effects on TG levels and glucose metabolism.
Among others, gene therapy substituting the loss of essential enzymes is already used for Lipoprotein
Lipase (LPL) deficiency in autosomal chylomicronaemia and is expected to eliminate the lack of Low-
Density Lipoprotein (LDL) receptors in patients with homozygous familial hypercholesterolaemia. Experimental
data of High-Density Lipoprotein (HDL) mimetics infusion therapy have shown a beneficial
effect on atherosclerotic plaques. Thus, many novel hypolipidaemic drugs targeting different aspects of
lipid metabolism are being investigated, although they need to be assessed in large trials to prove their
CV benefit and safety.

Abstract
Breast cancer is a major cause of death globally, and particularly in developed countries. Breast cancer is influenced by cholesterol membrane content, by affecting the signaling pathways modulating cell growth, adherence, and migration. Furthermore, steroid hormones are derived from cholesterol and these play a key role in the pathogenesis of breast cancer. Although most findings have reported an inverse association between serum high-density lipoprotein (HDL)-cholesterol level and the risk of breast cancer, there have been some reports of the opposite, and the association therefore remains unclear. HDL is principally known for participating in reverse cholesterol transport and has an inverse relationship with the cardiovascular risk. HDL is heterogeneous, with particles varying in composition, size, and structure, which can be altered under different circumstances, such as inflammation, aging, and certain diseases. It has also been proposed that HDL functionality might have a bearing on the breast cancer. Owing to the potential role of cholesterol in cancer, its reduction using statins, and particularly as an adjuvant during chemotherapy may be useful in the anticancer treatment, and may also be related to the decline in cancer mortality. Reconstituted HDLs have the ability to release chemotherapeutic drugs inside the cell. As a consequence, this may be a novel way to improve therapeutic targeting for the breast cancer on the basis of detrimental impacts of oxidized HDL on cancer development.

Abstract
Low-density lipoprotein cholesterol (LDL-C) is a major cardiovascular risk factor, but other lipid variables such as triglycerides (TRGs), high-density lipoprotein cholesterol (HDL-C) and lipoprotein a [Lp(a)] also affect cardiovascular risk. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors significantly lower LDL-C concentration but also modestly improve the concentrations of TRGs and HDL-C and more robustly decrease Lp(a) levels. The review presents the associated mechanisms of the beneficial effects of PCSK9 inhibitors on the other than LDL-C lipid variables, including the effects on lipid/apolipoprotein secretion and clearance and the heteroexchange between lipoproteins, as well as the possible effects on other variables involved in lipid metabolism such as sortilin. Proprotein convertase subtilisin/kexin type 9 inhibitors improve the overall lipid profile, and these beneficial effects may play a role in the reduction of cardiovascular risk.

Abstract
BACKGROUND Garlic has been shown to have cardiovascular protective and immunomodulatory properties. OBJECTIVES We updated a previous meta-analysis on the effect of garlic on blood pressure and reviewed the effect of garlic on cholesterol and immunity. METHODS We searched the Medline database for randomized controlled trials (RCTs) published between 1955 and December 2013 on the effect of garlic preparations on blood pressure. In addition, we reviewed the effect of garlic on cholesterol and immunity. RESULTS Our updated meta-analysis on the effect of garlic on blood pressure, which included 20 trials with 970 participants, showed a mean ± SE decrease in systolic blood pressure (SBP) of 5.1 ± 2.2 mm Hg (P < 0.001) and a mean ± SE decrease in diastolic blood pressure (DBP) of 2.5 ± 1.6 mm Hg (P < 0.002) compared with placebo. Subgroup analysis of trials in hypertensive subjects (SBP/DBP ≥140/90 mm Hg) at baseline revealed a larger significant reduction in SBP of 8.7 ± 2.2 mm Hg (P < 0.001; n = 10) and in DBP of 6.1 ± 1.3 mm Hg (P < 0.001; n = 6). A previously published meta-analysis on the effect of garlic on blood lipids, which included 39 primary RCTs and 2300 adults treated for a minimum of 2 wk, suggested garlic to be effective in reducing total and LDL cholesterol by 10% if taken for >2 mo by individuals with slightly elevated concentrations [e.g., total cholesterol >200 mg/dL (>5.5 mmol/L)]. Garlic has immunomodulating effects by increasing macrophage activity, natural killer cells, and the production of T and B cells. Clinical trials have shown garlic to significantly reduce the number, duration, and severity of upper respiratory infections. CONCLUSIONS Our review suggests that garlic supplements have the potential to lower blood pressure in hypertensive individuals, to regulate slightly elevated cholesterol concentrations, and to stimulate the immune system. Garlic supplements are highly tolerated and may be considered as a complementary treatment option for hypertension, slightly elevated cholesterol, and stimulation of immunity. Future long-term trials are needed to elucidate the effect of garlic on cardiovascular morbidity and mortality.

Abstract
Depressed levels of atheroprotective large HDL particles are common in obesity and cardiovascular disease (CVD). Increases in large HDL particles are favourably associated with reduced CVD event risk and coronary plaque burden. The objective of the study is to compare the effectiveness of low-carbohydrate diets and weight loss for increasing blood levels of large HDL particles at 1 year. This study was performed by screening for body mass index (BMI) and metabolic syndrome in 160 consecutive subjects referred to our out-patient Metabolic Unit in South Italy. We administered dietary advice to four small groups rather than individually. A single team comprised of a dietitian and physician administered diet-specific advice to each group. Large HDL particles at baseline and 1 year were measured using two-dimensional gel electrophoresis. Dietary intake was assessed via 3-day diet records. Although 1-year weight loss did not differ between diet groups (mean 4.4 %), increases in large HDL particles paralleled the degree of carbohydrate restriction across the four diets (p<0.001 for trend). Regression analysis indicated that magnitude of carbohydrate restriction (percentage of calories as carbohydrate at 1 year) and weight loss were each independent predictors of 1-year increases in large HDL concentration. Changes in HDL cholesterol concentration were modestly correlated with changes in large HDL particle concentration (r=0.47, p=.001). In conclusion, reduction of excess dietary carbohydrate and body weight improved large HDL levels. Comparison trials with cardiovascular outcomes are needed to more fully evaluate these findings.

Abstract
Dapagliflozin is a selective and reversible inhibitor of sodium-glucose linked transporter type 2 (SGLT2), which mediates approximately 90% of active renal glucose reabsorption in the early proximal tubule of the kidney. Dapagliflozin significantly reduces glucose reabsorption and decreases serum glucose concentration in an insulin-independent manner. The decrease of glucose reabsorption by dapagliflozin has also been associated with a reduction in body weight. Furthermore, the drug modestly reduces blood pressure levels through weight loss and its action as osmotic diuretic. Dapagliflozin has been approved as monotherapy in patients with type 2 diabetes mellitus (T2DM) who cannot tolerate metformin or in combination with other antidiabetic drugs, with the exception of pioglitazone due to the theoretical increased risk of bladder cancer. The drug should not be prescribed in patients with moderate or severe renal impairment or in patients at risk for developing volume depletion. Dapagliflozin is associated with increased incidence of genital and lower urinary tract infections, but these infections are usually mild to moderate and respond to standard antimicrobial treatment. Based on current evidence, dapagliflozin is a useful drug for patients with T2DM with a favorable safety profile. However, further research regarding the effects of dapagliflozin on cardiovascular outcomes is needed.

Abstract
BACKGROUND & AIMS Plasma levels of high-density lipoprotein (HDL) cholesterol are frequently found decreased in patients with inflammatory bowel disease (IBD). Therefore, and because HDL exerts anti-inflammatory activities, we investigated whether HDL and its major protein component apolipoprotein A-I (apoA-I) modulate mucosal inflammatory responses in vitro and in vivo. METHODS The human intestinal epithelial cell line T84 was used as the in vitro model for measuring the effects of HDL on the expression and secretion of tumor necrosis factor (TNF), interleukin-8 (IL-8), and intracellular adhesion molecule (ICAM). Nuclear factor-κB (NF-κB)-responsive promoter activity was studied by dual luciferase reporter assays. Mucosal damage from colitis induced by dextran sodium sulphate (DSS) and 2,4,6-trinitrobenzenesulfonic acid (TNBS) was scored by colonoscopy and histology in apoA-I transgenic (Tg) and apoA-I knockout (KO) and wild-type (WT) mice. Myeloperoxidase (MPO) activity and TNF and ICAM expression were determined in intestinal tissue samples. Autophagy was studied by Western blot analysis, immunofluorescence, and electron microscopy. RESULTS HDL and apoA-I down-regulated TNF-induced mRNA expression of TNF, IL-8, and ICAM, as well as TNF-induced NF-κB-responsive promoter activity. DSS/TNBS-treated apoA-I KO mice displayed increased mucosal damage upon both colonoscopy and histology, increased intestinal MPO activity and mRNA expression of TNF and ICAM as compared with WT and apoA-I Tg mice. In contrast, apoA-I Tg mice showed less severe symptoms monitored by colonoscopy and MPO activity in both the DSS and TNBS colitis models. In addition, HDL induced autophagy, leading to recruitment of phosphorylated IκB kinase to the autophagosome compartment, thereby preventing NF-κB activation and induction of cytokine expression. CONCLUSIONS Taken together, the in vitro and in vivo findings suggest that HDL and apoA-I suppress intestinal inflammation via autophagy and are potential therapeutic targets for the treatment of IBD.

Abstract
OBJECTIVE To investigate the relationship between HDL cholesterol (HDL-C) and cancer risk among type 2 diabetic patients. RESEARCH DESIGN AND METHODS We performed a retrospective cohort study of 14,169 men and 23,176 women with type 2 diabetes. Cox proportional hazards regression models were used to estimate the association of various levels of HDL cholesterol (HDL-C) with cancer risk. RESULTS During a mean follow-up period of 6.4 years, 3,711 type 2 diabetic patients had a cancer diagnosis. A significant inverse association between HDL-C and the risk of cancer was found among men and women. The multivariable-adjusted hazard ratios (HRs) of cancer at various levels of HDL-C at baseline (<30, 30-39.9, 40-49.9, 50-59.9, 60-69.9, 70-79.9, and ≥80 mg/dL) were 1.00, 0.87, 0.95, 1.01, 0.61, 0.45, and 0.37, respectively, in men (Ptrend = 0.027) and 1.00, 0.98, 0.88, 0.85, 0.84, 0.86, and 0.84, respectively, in women (Ptrend = 0.025). When stratified by race, BMI, smoking status, or medication use, the inverse association was still present. With an updated mean of HDL-C used in the analysis, the inverse association of HDL-C with cancer risk did not change. The inverse association substantially attenuated after excluding patients who died of or were diagnosed with cancer during the first 2 years of follow-up. CONCLUSIONS The study suggests an inverse association of HDL-C with cancer risk among men and women with type 2 diabetes, whereas the effect of HDL-C was partially mediated by reverse causation.

Effects of Methanol Extract of Breadfruit (Artocarpus altilis) on Atherogenic Indices and Redox Status of Cellular System of Hypercholesterolemic Male Rats. Adv Pharmacol Sci 2014; 2014:605425. [PMID: 24592277 PMCID: PMC3926424 DOI: 10.1155/2014/605425] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2013] [Revised: 12/17/2013] [Accepted: 12/18/2013] [Indexed: 02/06/2023] Open
Abstract
We investigated the effects of methanol extract of Artocarpus altilis (AA) on atherogenic indices and redox status of cellular system of rats fed with dietary cholesterol while Questran (QUE) served as standard. Biochemical indices such as total cholesterol (TC), triglycerides (TG), low- and high-density lipoproteins-cholesterol (LDL-C and HDL-C), aspartate and alanine aminotransferases (AST and ALT), lactate dehydrogenase (LDH), reduced glutathione, glutathione-s-transferase, glutathione peroxidase (GPx), catalase (CAT), superoxide dismutase (SOD), and lipid peroxidation (LPO) were assessed. Hypercholesterolemic (HC) rats had significantly increased relative weight of liver and heart. Dietary cholesterol caused a significant increase (P < 0.05) in the levels of serum, hepatic, and cardiac TC by 110%, 70%, and 85%, LDL-C by 79%, 82%, and 176%, and TG by 68%, 96%, and 62%, respectively. Treatment with AA significantly reduced the relative weight of the organs and lipid parameters. There were beneficial increases in serum and cardiac HDL-C levels in HC rats treated with AA. In HC rats, serum LDH, ALT, and AST activities and levels of LPO were increased, whereas hepatic and cardiac SOD, CAT, and GPx were reduced. All biochemical and histological alterations were ameliorated upon treatment with AA. Extract of AA had protective effects against dietary cholesterol-induced hypercholesterolemia.

Abstract
Dyslipidemia is a major risk factor for the development of cardiovascular diseases and statins are the common drugs used to correct dyslipidemia. Herein, we report a case where the subject was a nondiabetic, dyslipidemia patient on medication with Rosuvastatin. After the intake of Rosuvastatin, his triglycerides decreased to a minimum of 220 mg/dL. In order to augment the action of Rosuvastatin, he was advised to take 1.5 mg of Nichi Glucan food supplement, which is a 1,3-1,6 Beta Glucan derived from the black yeast, Aureobasidium pullulans, daily for 2 months. At the end of 2 months, his triglyceride levels decreased from 523 mg/dL (at start of the study) to 175 mg/dL. His VLDL levels, which were 104.6 mg/dL at the start of the study decreased to 35 mg/dL and the HDL cholesterol levels increased from 27 to 38 mg/dL. This is a first of its kind report on the effect of the black yeast derived 1,3-1,6 Beta Glucans on dyslipidemia not associated with diabetes. Thus supplementation of Nichi Glucan, 1,3- 1,6 Beta Glucan derived from the black yeast along with the routine medications was beneficial to treat dyslipidemia and a larger trial is needed to confirm the effects.

Abstract
BACKGROUND Relatively large number of dietary supplements and nutraceuticals have been studied for their supposed or demonstrated ability to reduce cholesterolemia in humans. OBJECTIVES The aim of this study was to evaluate the efficacy as antihypercholesterolemic and insulin-sensitizing agent of a combination of Berberis aristata/Silybum marianum extract (Berberol®) in a sample of dyslipidemic patients. A total of 102 dyslipidemic subjects were enrolled. After a 6 months run-in period of diet and physical activity, the patients were randomized to placebo or Berberis aristata/Silybum marianum extract 588 mg/105 mg, twice a day for 3 months. Berberis aristata/Silybum marianum and placebo were then interrupted for 2 months (washout period), and then restarted for further 3 months. Anthropometric and metabolic parameters were assessed; moreover, all patients underwent a glucagon stimulation test. RESULTS Berberis aristata/Silybum marianum reduced total cholesterol, triglycerides and low-density lipoprotein cholesterol and increased high-density lipoprotein cholesterol after 3 months from randomization and compared to placebo group. When Berberis aristata/Silybum marianum was interrupted, lipid profile worsened, and it improved again when nutraceutical combination was reintroduced. During the glucagon stimulation test, a higher increase of C-peptide levels and a lower increase in glycemia after the test with Berberis aristata/Silybum marianum compared to placebo, to baseline and to randomization were recorded. No patients had serious adverse events in both groups. CONCLUSION Berberis aristata/Silybum marianum is effective and safe in improving lipid profile and insulin secretion in euglycemic dyslipidemic patients.
