Background: Industrially processed trans-fatty acids (IP-TFA) have been linked to altered lipoprotein metabolism, inflammation and increased NT-proBNP. In patients with heart failure with preserved ejection fraction (HFpEF), associations of TFA blood levels with patient characteristics are unknown., Methods: This is a secondary analysis of the Aldo-DHF-RCT. From 422 patients, individual blood TFA were analyzed at baseline in n = 404 using the HS-Omega-3-Index ® methodology. Patient characteristics were: 67 ± 8 years, 53% female, NYHA II/III (87/13%), ejection fraction ≥ 50%, E/e' 7.1 ± 1.5; NT-proBNP 158 ng/L (IQR 82-298). A principal component analysis was conducted but not used for further analysis as cumulative variance for the first two PCs was low. Spearman's correlation coefficients as well as linear regression analyses, using sex and age as covariates, were used to describe associations of whole blood TFA with metabolic phenotype, functional capacity, echocardiographic markers for LVDF and neurohumoral activation at baseline and after 12 months., Results: Blood levels of the naturally occurring TFA C16:1n-7t were inversely associated with dyslipidemia, body mass index/truncal adiposity, surrogate markers for non-alcoholic fatty liver disease and inflammation at baseline/12 months. Conversely, IP-TFA C18:1n9t, C18:2n6tt and C18:2n6tc were positively associated with dyslipidemia and isomer C18:2n6ct with dysglycemia. C18:2n6tt and C18:2n6ct were inversely associated with submaximal aerobic capacity at baseline/12 months. No significant association was found between TFA and cardiac function., Conclusions: In HFpEF patients, higher blood levels of IP-TFA, but not naturally occurring TFA, were associated with dyslipidemia, dysglycemia and lower functional capacity. Blood TFAs, in particular C16:1n-7t, warrant further investigation as prognostic markers in HFpEF. Higher blood levels of industrially processed TFA, but not of the naturally occurring TFA C16:1n-7t, are associated with a higher risk cardiometabolic phenotype and prognostic of lower aerobic capacity in patients with HFpEF., (© 2023.

De novo lipogenesis (DNL)-related monounsaturated fatty acids (MUFAs) in the blood are associated with incident heart failure (HF). This observation's biological plausibility may be due to the potential of these MUFAs to induce proinflammatory pathways, endoplasmic reticulum stress, and insulin resistance, which are pathophysiologically relevant in HF. The associations of circulating MUFAs with cardiometabolic phenotypes in patients with heart failure with a preserved ejection fraction (HFpEF) are unknown. In this secondary analysis of the Aldosterone in Diastolic Heart Failure trial, circulating MUFAs were analysed in 404 patients using the HS-Omega-3-Index ® methodology. Patients were 67 ± 8 years old, 53% female, NYHA II/III (87/13%). The ejection fraction was ≥50%, E/e' 7.1 ± 1.5, and the median NT-proBNP 158 ng/L (IQR 82-298). Associations of MUFAs with metabolic, functional, and echocardiographic patient characteristics at baseline/12 months follow-up (12 mFU) were analysed using Spearman's correlation coefficients and linear regression analyses, using sex/age as covariates. Circulating levels of C16:1n7 and C18:1n9 were positively associated with BMI/truncal adiposity and associated traits (dysglycemia, atherogenic dyslipidemia, and biomarkers suggestive of non-alcoholic-fatty liver disease). They were furthermore inversely associated with functional capacity at baseline/12 mFU. In contrast, higher levels of C20:1n9 and C24:1n9 were associated with lower cardiometabolic risk and higher exercise capacity at baseline/12 mFU. In patients with HFpEF, circulating levels of individual MUFAs were differentially associated with cardiovascular risk factors. Our findings speak against categorizing FA based on physicochemical properties. Circulating MUFAs may warrant further investigation as prognostic markers in HFpEF.

Background: Circulating long-chain (LCSFAs) and very long-chain saturated fatty acids (VLSFAs) have been differentially linked to risk of incident heart failure (HF). In patients with heart failure with preserved ejection fraction (HFpEF), associations of blood SFA levels with patient characteristics are unknown., Methods: From the Aldo-DHF-RCT, whole blood SFAs were analyzed at baseline in n = 404 using the HS-Omega-3-Index ® methodology. Patient characteristics were 67 ± 8 years, 53% female, NYHA II/III (87%/13%), ejection fraction ≥50%, E/e' 7.1 ± 1.5; and median NT-proBNP 158 ng/L (IQR 82-298). Spearman´s correlation coefficients and linear regression analyses, using sex and age as covariates, were used to describe associations of blood SFAs with metabolic phenotype, functional capacity, cardiac function, and neurohumoral activation at baseline and after 12-month follow-up (12 mFU)., Results: In line with prior data supporting a potential role of de novo lipogenesis-related LCSFAs in the development of HF, we showed that baseline blood levels of C14:0 and C16:0 were associated with cardiovascular risk factors and/or lower exercise capacity in patients with HFpEF at baseline/12 mFU. Contrarily, the three major circulating VLSFAs, lignoceric acid (C24:0), behenic acid (C22:0), and arachidic acid (C20:0), as well as the LCSFA C18:0, were broadly associated with a lower risk phenotype, particularly a lower risk lipid profile. No associations were found between cardiac function and blood SFAs., Conclusions: Blood SFAs were differentially linked to biomarkers and anthropometric markers indicative of a higher-/lower-risk cardiometabolic phenotype in HFpEF patients. Blood SFA warrant further investigation as prognostic markers in HFpEF. One Sentence Summary: In patients with HFpEF, individual circulating blood SFAs were differentially associated with cardiometabolic phenotype and aerobic capacity.

Objectives: To evaluate associations of omega-3 fatty acid (O3-FA) blood levels with cardiometabolic risk markers, functional capacity and cardiac function/morphology in patients with heart failure with preserved ejection fraction (HFpEF)., Background: O3-FA have been linked to reduced risk for HF and associated phenotypic traits in experimental/clinical studies., Methods: This is a cross-sectional analysis of data from the Aldo-DHF-RCT. From 422 patients, the omega-3-index (O3I = EPA + DHA) was analyzed at baseline in n = 404 using the HS-Omega-3-Index ® methodology. Patient characteristics were; 67 ± 8 years, 53% female, NYHA II/III (87/13%), ejection fraction ≥ 50%, E/e' 7.1 ± 1.5; median NT-proBNP 158 ng/L (IQR 82-298). Pearson's correlation coefficient and multiple linear regression analyses, using sex and age as covariates, were used to describe associations of the O3I with metabolic phenotype, functional capacity, echocardiographic markers for LVDF, and neurohumoral activation at baseline/12 months., Results: The O3I was below (< 8%), within (8-11%), and higher (> 11%) than the target range in 374 (93%), 29 (7%), and 1 (0.2%) patients, respectively. Mean O3I was 5.7 ± 1.7%. The O3I was inversely associated with HbA1c (r = - 0.139, p = 0.006), triglycerides-to-HDL-C ratio (r = - 0.12, p = 0.017), triglycerides (r = - 0.117, p = 0.02), non-HDL-C (r = - 0.101, p = 0.044), body-mass-index (r = - 0.149, p = 0.003), waist circumference (r = - 0.121, p = 0.015), waist-to-height ratio (r = - 0.141, p = 0.005), and positively associated with submaximal aerobic capacity (r = 0.113, p = 0.023) and LVEF (r = 0.211, p < 0.001) at baseline. Higher O3I at baseline was predictive of submaximal aerobic capacity (β = 15.614, p < 0,001), maximal aerobic capacity (β = 0.399, p = 0.005) and LVEF (β = 0.698, p = 0.007) at 12 months., Conclusions: Higher O3I was associated with a more favorable cardiometabolic risk profile and predictive of higher submaximal/maximal aerobic capacity and lower BMI/truncal adiposity in HFpEF patients. Omega-3 fatty acid blood levels are inversely associated with cardiometabolic risk factors in HFpEF patients. Higher O3I was associated with a more favorable cardiometabolic risk profile and aerobic capacity (left) but did not correlate with echocardiographic markers for left ventricular diastolic function or neurohumoral activation (right). An O3I-driven intervention trial might be warranted to answer the question whether O3-FA in therapeutic doses (with the target O3I 8-11%) impact on echocardiographic markers for left ventricular diastolic function and neurohumoral activation in patients with HFpEF.

Current screening algorithms for type 2 diabetes (T2D) rely on fasting plasma glucose (FPG) and/or HbA1c. This fails to identify a sizeable subgroup of individuals in early stages of metabolic dysregulation who are at high risk for developing diabetes or cardiovascular disease. The Matsuda index, a combination of parameters derived from a fasting and postprandial insulin assay, is an early biomarker for metabolic dysregulation (i.e. insulin resistance/compensatory hyperinsulinemia). The aim of this analysis was to compare four widely available anthropometric and biochemical markers indicative of this condition [waist-to-height ratio (WHtR), hypertriglyceridemic-waist phenotype (HTW), triglycerides-to-HDL-C ratio (TG/HDL-C) and FPG] to the Matsuda index. This cross-sectional analysis included 2231 individuals with normal fasting glucose (NFG, n = 1333), impaired fasting glucose (IFG, n = 599) and T2D (n = 299) from an outpatient diabetes clinic in Germany and thus extended a prior analysis from our group done on the first two subgroups. We analyzed correlations of the Matsuda index with WHtR, HTW, TG/HDL-C and FPG and their predictive accuracies by correlation and logistic regression analyses and receiver operating characteristics. In the entire group and in NFG, IFG and T2D, the best associations were observed between the Matsuda index and the WHtR (r = - 0.458), followed by HTW phenotype (r = - 0.438). As for prediction accuracy, WHtR was superior to HTW, TG/HDL-C and FPG in the entire group (AUC 0.801) and NFG, IFG and T2D. A multivariable risk score for the prediction of insulin resistance was tested and demonstrated an area under the ROC curve of 0.765 for WHtR and its interaction with sex as predictor controlled by age and sex. The predictive power increased to 0.845 when FPG and TG/HDL-C were included. Using as a comparator the Matsuda index, WHtR, compared to HTW, TG/HDL-C and FPG, showed the best predictive value for detecting metabolic dysregulation. We conclude that WHtR, a widely available anthropometric index, could refine phenotypic screening for insulin resistance/hyperinsulinemia. This may ameliorate early identification of individuals who are candidates for appropriate therapeutic interventions aimed at addressing the twin epidemic of metabolic and cardiovascular disease in settings where more extended testing such as insulin assays are not feasible.

Current algorithms for assessing risk of atherosclerotic cardiovascular disease (ASCVD) and, in particular, the reliance on low-density lipoprotein (LDL) cholesterol in conditions where this measurement is discordant with apoB and LDL-particle concentrations fail to identify a sizeable part of the population at high risk for adverse cardiovascular events. This results in missed opportunities for ASCVD prevention, most notably in those with metabolic syndrome, prediabetes, and diabetes. There is substantial evidence that accumulation of ectopic fat and associated metabolic traits are markers for and pathogenic components of high-risk atherosclerosis. Conceptually, the subset of advanced lesions in high-risk atherosclerosis that triggers vascular complications is closely related to a set of coordinated high-risk traits clustering around a distinct metabolic phenotype. A key feature of this phenotype is accumulation of ectopic fat, which, coupled with age-related muscle loss, creates a milieu conducive for the development of ASCVD: atherogenic dyslipidemia, nonresolving inflammation, endothelial dysfunction, hyperinsulinemia, and impaired fibrinolysis. Sustained vascular inflammation, a hallmark of high-risk atherosclerosis, impairs plaque stabilization in this phenotype. This review describes how metabolic and inflammatory processes that are promoted in large measure by ectopic adiposity, as opposed to subcutaneous adipose tissue, relate to the pathogenesis of high-risk atherosclerosis. Clinical biomarkers indicative of these processes provide incremental information to standard risk factor algorithms and advanced lipid testing identifies atherogenic lipoprotein patterns that are below the discrimination level of standard lipid testing. This has the potential to enable improved identification of high-risk patients who are candidates for therapeutic interventions aimed at prevention of ASCVD.

Context: High dietary salt intake is known to aggravate arterial hypertension. This effect could be of particular relevance in the setting of primary aldosteronism (PA), which is associated with cardiovascular damage independent of blood pressure levels. The aim of this study was to determine the impact of therapy on salt intake in PA patients., Patients and Methods: A total of 148 consecutive PA patients (66 with unilateral and 82 with bilateral PA) from the database of the German Conn's Registry were included. Salt intake was quantified by 24-hour urinary sodium excretion before and after initiation of PA treatment., Study Design: Observational longitudinal cohort study., Setting: Tertiary care hospital., Results: At baseline, unilateral PA patients had a significantly higher urinary sodium excretion than patients with bilateral disease (205 vs 178 mmol/d, P = 0.047). Higher urinary sodium excretion correlated with an increased cardiovascular risk profile including proteinuria, impaired lipid, and glucose metabolism and was associated with higher daily doses of antihypertensive drugs to achieve blood pressure control. In unilateral disease, urinary sodium excretion dropped spontaneously to 176 mmol/d (P = 0.012) 1 year after unilateral adrenalectomy and remained low at 3 years of follow-up (174 mmol/d). In contrast, treatment with mineralocorticoid receptor antagonists (MRA) in bilateral PA patients was not associated with a significant change in urinary sodium excretion at follow-up (179 mmol/d vs 183 mmol/d)., Conclusion: PA patients consuming a high-salt diet, estimated based on urinary sodium excretion, respond to adrenalectomy with a significant reduction of salt intake, in contrast to MRA treatment., (© Endocrine Society 2019.)

Despite major efforts to reduce atherosclerotic cardiovascular disease (ASCVD) burden with conventional risk factor control, significant residual risk remains. Recent evidence on non-traditional determinants of cardiometabolic health has advanced our understanding of lifestyle-disease interactions. Chronic exposure to environmental stressors like poor diet quality, sedentarism, ambient air pollution and noise, sleep deprivation and psychosocial stress affect numerous traditional and non-traditional intermediary pathways related to ASCVD. These include body composition, cardiorespiratory fitness, muscle strength and functionality and the intestinal microbiome, which are increasingly recognized as major determinants of cardiovascular health. Evidence points to partially overlapping mechanisms, including effects on inflammatory and nutrient sensing pathways, endocrine signalling, autonomic function and autophagy. Of particular relevance is the potential of low-risk lifestyle factors to impact on plaque vulnerability through altered adipose tissue and skeletal muscle phenotype and secretome. Collectively, low-risk lifestyle factors cause a set of phenotypic adaptations shifting tissue cross-talk from a proinflammatory milieu conducive for high-risk atherosclerosis to an anti-atherogenic milieu. The ketone body ß-hydroxybutyrate, through inhibition of the NLRP-3 inflammasome, is likely to be an intermediary for many of these observed benefits. Adhering to low-risk lifestyle factors adds to the prognostic value of optimal risk factor management, and benefit occurs even when the impact on conventional risk markers is discouragingly minimal or not present. The aims of this review are (a) to discuss novel lifestyle risk factors and their underlying biochemical principles and (b) to provide new perspectives on potentially more feasible recommendations to improve long-term adherence to low-risk lifestyle factors.

Context: Primary aldosteronism (PA) represents a secondary form of arterial hypertension that can be cured by surgery. Evidence of adrenal insufficiency (AI) was recently found in patients with PA who had undergone unilateral adrenalectomy (uADX)., Objective: To study the incidence and long-term outcome of postoperative AI after uADX for PA., Design: Prospective registry study (August 2014 until the end of 2018)., Setting: Tertiary referral center., Patients: One hundred consecutive patients undergoing uADX for PA were included. All patients underwent postoperative ACTH stimulation testing., Intervention: Postoperative ACTH stimulation testing to identify patients with AI., Main Outcome Measures: Incidence of patients with postoperative AI and definition of long-term outcome., Results: Twenty-seven percent of patients developed postoperative AI. Of these, 48% had postoperative ACTH stimulation serum cortisol levels ≤13.5 µg/dL (severe AI); 52% were classified into the group with moderate AI (stimulated serum cortisol levels: 13.5 to 17 µg/dL). Patients with severe AI required significantly longer hydrocortisone replacement therapy than the moderate group (median [25th, 75th percentiles]: 353 [294, 476] days; 95% CI: 284 to 322 days; vs 74 [32, 293] days; 95% CI: 11 to 137 days; P = 0.016). One patient with severe AI was hospitalized for an acute adrenal crisis. With a cumulative follow-up of 14.5 years, this produced an incidence rate of 6.9 adrenal crises per 100 patient-years., Conclusion: We suggest performing postoperative ACTH stimulation tests in all patients who undergo uADX for PA., (Copyright © 2019 Endocrine Society.)

In patients with primary aldosteronism, specific treatment provides prognostic benefit over optimal antihypertensive therapy and is therefore crucial to reduce mortality and morbidity in this subgroup of patients with hypertension. Prognostic relevance has been shown for adrenalectomy in unilateral disease and for medical treatment with mineralocorticoid receptor antagonists in bilateral adrenal hyperplasia. Collectively, evidence points to the superiority of surgical treatment compared to medical treatment. The causal approach of removing the mineralocorticoid excess, as well as the often-accompanying glucocorticoid excess, might provide one biologically plausible explanation for the observation of slightly better outcomes with surgical therapy. However, in patients living with primary aldosteronism, medical treatment is often insufficient for three major reasons. First and foremost, no marker of sufficient aldosterone blockade has yet been established and therefore adequate treatment of the aldosterone excess is often dismissed as a treatment goal. Second, side effects often limit patient compliance. Third, as recommendations differ from other indications like heart failure, drug dosing is often inadequate. The aim of this review is first to provide an overview over medical treatment options and second to review potential markers for treatment surveillance in patients with primary aldosteronism.

Objective: Saline infusion test (SIT) and captopril challenge test (CCT) are standard confirmatory procedures routinely used in the diagnostic work-up of primary aldosteronism (PA). However, side effects and complications during testing have not been systematically studied., Design: We performed a cohort study with patients undergoing SIT and/or CCT in two centers from 2016 until 2018., Methods: We studied 272 study participants with suspected PA enrolled at two outpatient centers in Germany. We assessed the frequency and severity of side effects during adjustment of blood pressure medication and during SIT and CCT., Results: During the adjustment phase prior confirmatory testing, side effects including palpitations, headaches, edema and hypertensive episodes occurred in 18.4% of study participants. Side effects were associated with higher defined daily doses (DDD) (r = 0.25, P < 0.005), number of antihypertensive drugs (r = 0.285, P < 0.005) and higher blood pressure (r = 0.145, P = 0.019). During SIT, 17.5% of study participants had side effects, associated with higher blood pressure (systolic: r = 0.541, P < 0.0005; diastolic: r = 0.426, P < 0.0005) and DDDs (r = 0.727, P < 0.0005). During CCT, only 1.5% of study participants developed side effects., Conclusions: In contrast to the high rate of side effects during SIT, CCT appears to be the safer test with a very low event rate. This makes CCT especially suitable for severely hypertensive patients.

Purpose of Review: Steroid profiling and immunohistochemistry are both promising new tools used to improve diagnostic accuracy in the work-up of primary aldosteronism (PA) and to predict treatment outcomes. Herein, we review the recent literature and present an outlook to the future of diagnostics and therapeutic decision-making in patients with PA., Recent Finding: PA is the most common endocrine cause of arterial hypertension and unilateral forms of the disease are potentially curable by surgical resection of the overactive adrenal. Recent studies have shown that adrenal steroid profiling by liquid chromatography-tandem mass spectrometry (LC-MS/MS) can be helpful for subtyping unilateral and bilateral forms of PA, classifying patients with a unilateral aldosterone-producing adenoma (APA) according to the presence of driver mutations of aldosterone production in APAs, and potentially predicting the outcomes of surgical treatment for unilateral PA. Following adrenalectomy, immunohistochemistry of aldosterone synthase (CYP11B2) in resected adrenals is a new tool to analyze "functional" histopathology and may be an indicator of biochemical outcomes after surgery. Biochemical and clinical outcomes of therapy in PA vary widely among patients. Peripheral venous steroid profiling at baseline could improve diagnostic accuracy and help in surgical decision-making in cases of a suspected APA; results of "functional" histopathology could help determine which patients are likely to need close post-surgical follow-up for persistent aldosteronism.

The prevalence of dementias is on the rise, increases exponentially with age and constitutes a major healthcare burden nationally and worldwide. Dementias are clinically heterogeneous and encompass numerous etiologies. Noteworthy, late onset dementias are closely related to vascular and metabolic risk factors in midlife. Cardiometabolic risk factors commonly precede the onset of cognitive decline for decades. This opens a huge window for prevention. Given the lack of established pharmacological options for treatment of most dementias, preventive strategies are of utmost importance. Several factors have been identified that have the potential to preserve a healthy metabolic phenotype and to attenuate the onset of late onset dementias. Evidence exists for low-risk lifestyle factors including a real food dietary pattern, an adequate supply with long chain omega-3 fatty acids, regular physical activity and restorative sleep, with multimodal concepts showing the greatest cumulative benefit., Competing Interests: NW, BL, MB und KL geben an, dass kein Interessenkonflikt besteht.

Cardiovascular disease is the number one cause of death globally. Poor diet constitutes a key factor in the initiation and progression of cardiovascular disease and has become the leading risk factor for disability and death worldwide. Therefore, addressing suboptimal nutrition is of key prognostic relevance in primary and secondary prevention of metabolic vascular syndrome.Metabolic vascular syndrome is a multidimensional network of acquired cardiometabolic risk factors closely related to insulin resistance (IR) and concomitant hyperinsulinemia. IR, being the underlying cause of metabolic vascular syndrome and certain types of cancer, should attract the attention of every clinician. As changes in lipoprotein metabolism are one of the earliest indicators of metabolic dysfunction, a relevant biomarker for identifying individuals with IR is the TAG/HDL-C ratio.IR - and concomitant metabolic vascular risk - can be effectively treated by lifestyle intervention. If IR is present, dietary carbohydrate restriction has consistently been shown to be superior to dietary fat restriction in reversing metabolic dysfunction. The beneficial effects of carbohydrate restricted diets on metabolic vascular risk are independent of BMI - diet quality therefore confers patient benefit beyond weight reduction.The effect of single nutrients on isolated lipid surrogate markers such as LDL-C does not capture their global effect on metabolic vascular risk.Targeting IR with a low glycemic load, real food diet will reduce overall energy density and will improve all risk factors of metabolic vascular syndrome. In particular, replacing refined carbohydrates with healthy fats in the context of a Mediterranean style-, low carbohydrate and calorie-unrestricted dietary pattern has been shown to significantly reduce burden of metabolic vascular disease., Competing Interests: Disclosure The authors report no conflicts of interest in this work., (© Georg Thieme Verlag KG Stuttgart · New York.)

Background: Transcatheter aortic valve implantation (TAVI) is increasingly applied for aortic stenosis in elderly patients with impaired mobility and reduced quality of life. These patients may particularly benefit from postinterventional exercise programs, but no randomized study has evaluated the safety and efficacy of exercise in this population., Methods: In a prospective pilot study, 30 patients after TAVI (mean age, 81±6 years, 44% female, 83±34 days postintervention) were randomly allocated 1:1 to a training group (TG) performing 8 weeks of supervised combined endurance and resistance exercise or to usual care. The formal primary efficacy end point was between-group difference in change in peak oxygen uptake assessed by cardiopulmonary exercise testing; secondary end points included muscular strength, 6-minute walk distance, and quality of life (Kansas City Cardiomyopathy Questionnaire and Medical Outcomes Study 12-Item Short-Form Health Survey questionnaires). Safety was assessed by documenting training-related adverse events, prosthesis, and renal function., Results: Significant changes in favor of TG were observed for peak oxygen uptake (group difference, 3.7 mL/min per kg [95% CI, 1.1-6.3; P=.007]), muscular strength (bench press, 6 kg [95% CI, 3-10; P=.002]; rowing, 7 kg [95% CI, 3-11; P<.001]; pulldown, 9 kg [95% CI, 4-14; P=.001]; shoulder press, 5 kg [95% CI, 1-8; P=.008]; leg press, 17 kg [95% CI 6-28; P=.005]), components of quality of life (Kansas City Cardiomyopathy Questionnaire physical limitation, 19.2 [95% CI, 4.1-34.2; P=.015]; symptom burden, 12.3 [95% CI, 0.5-24.0; P=.041]; clinical summary, 12.4 [3.4-21.4; P=.009]), but not for other questionnaire subscales and 6-minute walk distance (15 m [95% CI, -23 to 53; P=.428]). Three dropouts unrelated to exercise occurred (TG=2; usual care,=1); prosthesis and renal function were not affected by the exercise intervention., Conclusions: In patients after TAVI, exercise training appears safe and highly effective with respect to improvements in exercise capacity, muscular strength, and quality of life., Clinical Trial Registration: Clinicaltrials.govNCT01935297., (Copyright © 2016 Elsevier Inc.
