Association of albumin to non-high-density lipoprotein cholesterol ratio with mortality in peritoneal dialysis patients. Ren Fail 2024; 46:2299601. [PMID: 38193165 PMCID: PMC10778424 DOI: 10.1080/0886022x.2023.2299601] [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: 07/17/2023] [Accepted: 12/21/2023] [Indexed: 01/10/2024] Open
Abstract
OBJECTIVE Malnutrition and inflammation are associated with mortality in peritoneal dialysis (PD) patients. Serum albumin and non-high-density lipoprotein cholesterol (non-HDL-C) are independently associated with mortality in PD patients. Combining albumin and non-HDL-C with mortality may be more plausible in clinical practice. METHODS This retrospective cohort study included 1954 Chinese PD patients from 1 January 2009 to 31 December 2016. Kaplan-Meier curve was used to determine the relationship between albumin to non-HDL-C ratio and all-cause mortality. Cox regression analysis was applied to assess the independent predictive value while adjusting for confounding factors. Competitive risk analysis was used to examine the effects of other outcomes on all-cause mortality prognosis. RESULTS In the 33-month follow-up period, there were 538 all-cause deaths. Kaplan-Meier analysis presented significant differences in all-cause mortality. Multivariate Cox regression showed that the risk of all-cause mortality was lower in the moderate group (9.36-12.79) (HR, 0.731; 95% CI, 0.593-0.902, p = 0.004) and the highest group (>12.79) (HR, 0.705; 95% CI, 0.565-0.879, p = 0.002) compared to the lowest group (≤9.36). Competitive risk analysis revealed significant differences for all-cause mortality (p < 0.001), while there was no statistical significance for other competing events. CONCLUSIONS Low albumin to non-HDL-C ratio was associated with a high risk of all-cause mortality in PD patients. It may serve as a potential prognostic biomarker in PD patients.

de Oliveira AD, Dos Santos AR, de Oliveira LC, Nogueira Neto JF. The relevance of the optional use of fasting in laboratory measurements that make up the lipid profile: A systematic literature review. J Pharm Biomed Anal 2024; 240:115925. [PMID: 38154369 DOI: 10.1016/j.jpba.2023.115925] [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: 05/08/2023] [Revised: 10/28/2023] [Accepted: 12/13/2023] [Indexed: 12/30/2023]
Abstract
The objective of this study was to evaluate the impact of fasting easing on laboratory measurements of the lipid profile, in order to contribute to the fidelity of interpretation of laboratory results. Starting in October 2022, a Systematic Literature Review (SRL) was carried out, using articles indexed in the electronic databases PubMed/MEDLINE, EMBASE, Scopus, LILACS and Cochrane Library, following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes Group (PRISMA). This RSL was registered with PROSPERO, under registration number CRD42022370007. For inclusion, articles had to be original and developed in humans. After evaluating the methodological quality and analyzing the risk of bias, we obtained 16 articles published between 1994 and 2021, providing data on a total of 398,709 individuals, aged between 3 and 93 years. According to the selected studies, lipid profile measurements performed with flexible fasting, in addition to bringing benefits to patients and the pre-analytical system of the clinical laboratory, are more suitable for determining cardiovascular risk, mainly through the assessment of values obtained in the determination of triglycerides. It is therefore concluded that the optional use of fasting must be established through medical advice. In addition, laboratory methods and readings must be readjusted to this reality, informing through the report the parameters related to the lipid profile with and without the use of a 12-hour fast.

Non-HDL cholesterol and long-term follow-up outcomes in patients with metabolic syndrome. Lipids Health Dis 2023; 22:165. [PMID: 37794473 PMCID: PMC10548659 DOI: 10.1186/s12944-023-01923-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Accepted: 09/11/2023] [Indexed: 10/06/2023] Open
Abstract
BACKGROUND Non-high-density lipoprotein-cholesterol (non-HDL-C) has been identified as a potential biomarker for metabolic syndrome (MetS). However, its predictive capability for MetS varies among different ethnic groups, necessitating further investigation. This study aimed to assess the role of non-HDL-C in the early diagnosis of MetS in the Iranian population through a longitudinal study with a 10-year follow-up period. METHODS Our study enrolled 4684 individuals from the MASHAD (Mashhad Stroke and Heart Atherosclerotic Disorder) cohort who were followed for 10 years to examine the association between non-HDL-C and the incidence of MetS. Additionally, the contribution of individual MetS components to the overall burden was evaluated. RESULTS A total of 1599 subjects developed MetS, while 3085 did not. Non-HDL-C levels ≥ 130 were associated with a 42% higher risk of developing MetS (relative risk (RR), 1.42; 95% confidence interval (CI), 1.25-1.62). Regarding MetS components, elevated waist circumference (WC) showed the strongest association with MetS incidence (RR, 2.32; 95% CI, 1.45-2.9), whereas triglyceride (TG) levels ≥ 150 mg/dL demonstrated the weakest association (RR, 1.23; 95% CI, 1.04-1.46). Additionally, higher HDL-C levels were reported to be 20% protective against the risk of MetS (RR, 0.8; 95% CI, 0.73-0.86). Moreover, fasting blood glucose (FBG) levels ≥ 100 mg/dL were not significantly linked to MetS burden, while systolic blood pressure (BP) levels ≥ 130 mmHg or diastolic BP levels ≥ 85 mmHg increased the risk of MetS incidence (RR, 1.25; 95% CI: 1.11-1.41). CONCLUSIONS Elevated non-HDL-C and increased WC serve as significant predictors of MetS in Iranians. Strategies targeting non-HDL-C levels and weight loss should be emphasized to mitigate the risk of MetS development.

Hypertriglyceridemia is associated with decline of estimated glomerular filtration rate and risk of end-stage kidney disease in a real-word Italian cohort: Evidence from the TG-RENAL Study. Eur J Intern Med 2023; 111:90-96. [PMID: 36906475 DOI: 10.1016/j.ejim.2023.02.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 02/17/2023] [Accepted: 02/20/2023] [Indexed: 03/12/2023]
Abstract
BACKGROUND This analysis investigated the role of hypertriglyceridemia on renal function decline and development of end-stage kidney disease (ESKD) in a real-world clinical setting. METHODS A retrospective analysis using administrative databases of 3 Italian Local Health Units was performed searching patients with at least one plasma triglyceride (TG) measurement between 2013 and June 2020, followed-up until June 2021. Outcome measures included reduction in estimated glomerular filtration rate (eGFR) ≥30% from baseline and ESKD onset. Subjects with normal (normal-TG), high (HTG) and very high TG levels (vHTG) (respectively <150 mg/dL, 150-500 mg/dL and >500 mg/dL) were comparatively evaluated. RESULTS Overall 45,000 subjects (39,935 normal-TGs, 5,029 HTG and 36 vHTG) with baseline eGFR of 96.0 ± 66.4 mL/min were considered. The incidence of eGFR reduction was 27.1 and 31.1 and 35.1 per 1000 person-years, in normal-TG, HTG and vHTG subjects, respectively (P<0.01). The incidence of ESKD was 0.7 and 0.9 per 1000 person-years, in normal-TG and HTG/vHTG subjects, respectively (P<0.01). Univariate and multivariate analyses revealed that HTG subjects had a risk of eGFR reduction or ESKD occurrence (composite endpoint) increased by 48% compared to normal-TG subjects (adjusted OR:1.485, 95%CI 1.300-1.696; P<0.001). Moreover, each 50 mg/dL increase in TG levels resulted in significantly greater risk of eGFR reduction (OR:1.062, 95%CI 1.039-1.086 P<0.001) and ESKD (OR:1.174, 95%CI 1.070-1.289, P = 0.001). CONCLUSIONS This real-word analysis in a large cohort of individuals with low-to-moderate cardiovascular risk suggests that moderate-to-severe elevation of plasma TG levels is associated with a significantly increased risk of long-term kidney function deterioration.

ENVIRONMENTAL HEALTH PERSPECTIVES 2022; 130:97002. [PMID: 36069575 PMCID: PMC9450637 DOI: 10.1289/ehp11033] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 07/06/2022] [Accepted: 08/17/2022] [Indexed: 05/26/2023]
Abstract
BACKGROUND Residents of Wilmington, North, Carolina, were exposed to drinking water contaminated by fluoroethers and legacy per- and polyfluoroalkyl substances (PFAS), such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), with fluoroether exposure occurring from 1980 to 2017. PFOA and PFOS have previously been associated with metabolic dysfunction; however, few prior studies have examined associations between other PFAS and lipid levels. OBJECTIVES We measured the association between serum fluoroether and legacy PFAS levels and various cholesterol outcomes. METHODS Participants in the GenX Exposure Study contributed nonfasting blood samples in November 2017 and May 2018 that were analyzed for 20 PFAS (10 legacy, 10 fluoroethers) and serum lipids [total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides] and calculated non-HDL cholesterol. We estimated covariate-adjusted associations between quartiles of exposure to each of the PFAS measures (as well as the summed concentrations of legacy PFAS, fluoroethers, and all 10 targeted PFAS) and lipid outcomes by fitting inverse probability of treatment weighted linear regressions. RESULTS In this cross-sectional study of 326 participants (age range 6-86 y), eight PFAS were detected in > 50 % of the population. For PFOS and perfluorononanoic acid (PFNA), non-HDL cholesterol was approximately 5 mg / dL higher per exposure quartile increase: [PFOS: 4.89; 95% confidence interval (CI): 0.10, 9.68 and PFNA: 5.25 (95% CI: 0.39, 10.1)], whereas total cholesterol was approximately 6 mg / dL higher per quartile [PFOS: 5.71 (95% CI: 0.38, 11.0), PFNA: 5.92 (95% CI: 0.19, 11.7)]. In age-stratified analyses, associations were strongest among the oldest participants. Two fluoroethers were associated with higher HDL, whereas other fluoroether compounds were not associated with serum lipid levels. DISCUSSION PFNA and PFOS were associated with higher levels of total and non-HDL cholesterol, with associations larger in magnitude among older adults. In the presence of these legacy PFAS, fluoroethers appeared to be associated with HDL but not non-HDL lipid measures. https://doi.org/10.1289/EHP11033.

Abstract
Background Idiopathic membranous nephropathy (IMN) may have various clinical outcomes. Hyperlipidemia is quite common in IMN. However, the utility of the lipid profile in predicting outcomes remains unknown. This study aimed to explore the correlation between hyperlipidemia and proteinuria remission in IMN. Methods 256 patients who diagnosed with IMN confirmed by renal biopsy in Wuhan Tongji Hospital from January 2016 to October 2020 were included in this study. The end point was defined as a combination of partial and complete remission. Cox proportional-hazards regression analysis and Kaplan–Meier curve were applied to assess the prognostic value of the lipid profile for proteinuria remission. Results A total of 153 (59.8%) patients achieved remission and 103 (40.2%) did not. The levels of total cholesterol, low-density lipoprotein, and non-high-density lipoprotein were significantly lower in the remission group than in the non-remission group. Non-high-density lipoprotein level revealed the strongest correlation with proteinuria (Spearman’s rho = 0.42; P < 0.001). The multivariate analysis demonstrated that serum total cholesterol [hazard ratio (HR): 0.883; 95% confidence interval (CI): 0.813–0.958; P = 0.003] and non-high-density lipoprotein cholesterol (HR: 0.892; 95% CI: 0.820–0.970; P = 0.007) levels were independent markers to predict proteinuria remission in IMN. Conclusions Among the lipid profile, the non-high-density lipoprotein level exhibited the strongest correlation with proteinuria in IMN. Moreover, elevated serum cholesterol and non-high-density lipoprotein cholesterol concentrations at baseline predicted probability of proteinuria non-remission in IMN.

Abstract
BACKGROUND The association between non-high-density lipoprotein cholesterol (non-HDL-C) and mortality in patients undergoing peritoneal dialysis (PD) is unclear. OBJECTIVE The aim of this study was to evaluate the association of non-HDL-C with cardiovascular (CV) and all-cause mortality in PD patients. METHODS We conducted a prospective cohort study. A total of 1,616 incident PD patients from a single PD center in South China were followed for a median of 47.6 months. The independent association of non-HDL-C with CV and all-cause mortality was evaluated by a Cox regression analysis. RESULTS During the follow-up period, 508 (31.4%) patients died, of which 249 (49.0%) were due to CV events. Atherosclerotic CV mortality accounted for 59.8% of CV mortality. In multivariable models, for 1-SD increase in non-HDL-C level, the hazard ratios (HRs) for CV and all-cause mortality were 1.52 [95% confidence interval (CI), 1.32-1.75; P < 0.001)] and 1.24 (95% CI, 1.12-1.39; P < 0.001), respectively. Furthermore, non-HDL-C was positively associated with atherosclerotic CV mortality (HR, 1.29; 95% CI, 1.09-1.52; P = 0.004) but not associated with nonatherosclerotic CV mortality (HR, 0.79; 95% CI, 0.59-1.05; P = 0.108). The quartile analyses showed a similar pattern to the continuous variable analyses of non-HDL-C levels for CV and all-cause mortality but did not demonstrate statistical significance for atherosclerotic or nonatherosclerotic CV mortality. CONCLUSION An elevated non-HDL-C level was independently associated with an increased risk of CV mortality, especially atherosclerotic CV mortality, and all-cause mortality in incident PD patients.

Abstract
Background There is accumulating evidence that serum levels of non–high‐density lipoprotein cholesterol (non–HDL‐C) are a more accurate predictor of cardiovascular outcomes when compared with low‐density lipoprotein cholesterol. However, we recently found that higher serum concentrations of triglycerides are associated with better outcomes in patients undergoing hemodialysis. Therefore, we hypothesized that the association of serum levels of non–HDL‐C (which includes triglyceride‐rich lipoproteins) with outcomes may also be different in patients undergoing hemodialysis when compared with other patient populations. Methods and Results We studied the association of baseline and time‐dependent serum levels of non–HDL‐C with all‐cause and cardiovascular mortality using Cox proportional hazard regression models in a nationally representative cohort of 50 118 patients undergoing incident hemodialysis from January 1, 2007, to December 31, 2011. In time‐dependent models adjusted for case mix and surrogates of malnutrition and inflammation, a graded inverse association between non–HDL‐C level and mortality was demonstrated with hazard ratios (95% confidence intervals) of the lowest (<60 mg/dL) and highest (≥160 mg/dL) categories: 1.88 (1.72–2.06) and 0.73 (0.64–0.83) for all‐cause mortality and 2.07 (1.78–2.41) and 0.75 (0.60–0.93) for cardiovascular mortality, respectively (reference, 100–115 mg/dL). In analyses using baseline values, non–HDL‐C levels <100 mg/dL were also associated with significantly higher mortality risk across all levels of adjustment. Similar associations were found when evaluating non‐HDL/HDL cholesterol ratio and mortality, with the highest all‐cause and cardiovascular mortality being observed in patients with decreased non‐HDL/HDL‐C ratio (<2.5). Conclusions Contrary to the general population, decrements in non–HDL‐C and non‐HDL/HDL cholesterol ratio were paradoxically associated with increased all‐cause and cardiovascular mortality in patients undergoing incident hemodialysis. The underlying mechanisms responsible for these associations await further investigation.

Abstract
BACKGROUND Non-high-density lipoprotein cholesterol (non-HDL-C) has been proposed as a predictor of cardiovascular disease (CVD) in the general population. The aim of this study was to evaluate the utility of non-HDL-C in predicting CV mortality in chronic hemodialysis (HD) patients. METHODS We calculated the serum non-HDL-C level of 259 HD patients by subtracting their HDL-C levels from their total cholesterol. Cox proportional hazards models were used to estimate the hazards ratio (HR) for CV mortality and the 95% confidence interval (CI). A receiver-operating characteristic (ROC) analysis was performed to estimate the relationship between sensitivity and specificity of a diagnostic parameter. RESULTS There were 44 deaths (17.0%) during the follow-up period, 33 (12.7%) of which were due to CVD. A multivariate Cox analysis with adjustments for age, diabetes, dialysis vintage, systolic blood pressure, serum albumin, and lipid levels showed that non-HDL-C was an independent predictor of CV mortality (HR 1.015, 95% CI 1.004-1.025, p = 0.0083). An ROC analysis showed that the plots of the non-HDL-C levels yielded significant specificity and sensitivity for predicting the risk of CVD mortality in HD patients [area under the curve (AUC) 0.62416; p = 0.0366; cutoff value 111.0 mg/dl]. The Kaplan-Meier survival curves of HD patients showed significant differences in CV mortality according to their tertiles with respect to serum non-HDL-C levels (p = 0.0165). CONCLUSION The results of this study suggest that serum non-HDL-C level is a significant CV mortality predictor of chronic HD patients.

Abstract
INTRODUCTION Non-high-density lipoprotein cholesterol (non-HDL-c) may be a better indicator of atherogenicity in the hemodialysis population. PURPOSE To investigate the correlation of non-HDL-c with anthropometric measurements associated to cardiovascular risk, such as body mass index, waist circumference, waist-to-height ratio, waist-to-height(2) ratio, and waist-to-hip circumference ratio. METHODS We evaluated anthropometric markers and lipids in 86 hemodialysis patients, and the correlation between them was investigated. RESULTS Non-HDL-c had a positive correlation with body mass index (r = 0.273; P = .01), waist circumference (r = 0.375; P = .000), waist-to-height ratio (r = 0.333; P = .002), waist-to-height(2) ratio (r = 0.270; P = .012), and waist-to-hip circumference ratio (r = 0.356; P = .001). CONCLUSIONS This study detected a positive and significant correlation between non-HDL-c, but not low-density lipoprotein cholesterol, and the anthropometric cardiovascular risk indexes. We could suggest that non-HDL-c can be used as a cardiovascular risk factor indicator among dialysis patients.

Abstract
Levels of fibroblast growth factor (FGF) 23, a phosphatonin, are frequently elevated in patients with end-stage renal disease (ESRD) who are on maintenance hemodialysis (MHD). However, the role of FGF23 remains unclear because renal FGF receptor function might be impaired. The present cross-sectional study examines a cohort of patients (n = 196) on MHD who were not undergoing therapy with lipid-lowering drugs including sevelamer. Non-fasting venous blood samples were withdrawn before the hemodialysis (HD) session on the third day after the previous HD session to measure serum levels of albumin, calcium (Ca), phosphate (P), alkaline phosphatase, intact parathyroid hormone (PTH), total cholesterol (C), high-density lipoprotein (HDL)-C, low-density lipoprotein(LDL)-C, oxidative LDL-C, high-sensitivity C-reactive protein (HsCRP), interleukin-6 (IL-6), and FGF23. Nutritional status was assessed using the geriatric nutritional risk index (GNRI). Carotid intima-medial thickness (CIMT) was assessed using a B-mode ultrasound scanner. FGF23 was positively correlated with P, Ca(alb)xP product, and intact PTH, and inversely correlated with C and non-HDL-C. In the higher FGF23 tertile, levels of both non-HDL-C and C were significantly decreased and CIMT was less elevated compared to the lower FGF23 tertile. Multivariate analysis showed that the higher FGF23 tertile was independently associated with decreases in C (adjusted r(2) = 0.14) and non-HDL-C (adjusted r(2) = 0.20) levels and with a less-pronounced increase in CIMT (adjusted r(2) = 0.14). High FGF23 appears to be an independent biomarker of a decrease in C and non-HDL-C that is negatively associated with atherosclerosis in patients on MHD.

Abstract
BACKGROUND AND OBJECTIVES Oxidized HDL (oxHDL) may behave as proinflammatory HDL because of reduced anti-inflammatory capacity and is considered a risk factor for mortality in patients on maintenance hemodialysis (MHD). The study presented here assessed the effect of oxHDL on protein-energy wasting (PEW) in MHD patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This prospective study examined a cohort of MHD patients (n = 176) who were not taking lipid-lowering drugs. Blood samples were obtained to measure albumin, lipids, high-sensitivity C-reactive protein (hsCRP), oxidized LDL (oxLDL), and oxHDL. PEW was assessed by subjective global assessment (SGA) and geriatric nutritional risk index (GNRI). Measurements and assessment of nutritional status were followed up 1 year later. RESULTS OxHDL was significantly increased in patients with PEW at baseline. High oxHDL and high hsCRP were significantly associated with PEW, and receiver operating characteristic curves for oxHDL and hsCRP showed statistically similar accuracy for predicting SGA-positive status. According to multivariate regression models, high oxHDL had a significant influence on PEW in patients, particularly those with high hsCRP. Decreased changes in GNRI and high prevalence of SGA-positive status at 1 year were more common in patients with high oxHDL at baseline and 1 year later than in patients with low oxHDL at both time points. CONCLUSIONS A high oxHDL state may be associated with PEW estimated by GNRI and SGA, particularly concomitant with inflammation in MHD patients.

Abstract
OBJECTIVE We examined the effects of commercially available unsaturated fat dietary supplements on blood lipids, and on markers of malnutrition and inflammation, in an adult population of hemodialysis (HD) patients. DESIGN This was a restricted, randomized (equal blocks), investigator-blinded 2x6 week crossover trial, without a washout interval. SETTING This study was conducted at the Department of Nephrology, Copenhagen University Hospital Herlev, Herlev, Denmark, in spring 2007. PATIENTS Participants included 40 (30 males and 10 females) stable, adult patients undergoing regular HD, with a mean age of 64.6 years and a mean body mass index of 23.3kg/m(2). INTERVENTION In addition to patients' habitual diets, oral unsaturated fat supplements (90mL of Calogen [SHS International, Ltd., Liverpool, UK] and 4 capsules of Pikasol [Dansk Droge, Ishoej, Denmark]) were given in one period, whereas no supplements were given in the other. Dietary supplements contributed 1.8 MJ (430kcal), 47g fat, 26.5g monounsaturated fatty acids, and 3g marine n-3 polyunsaturated fatty acids per day. Blood sampling and nutritional assessments were performed at baseline, after 6 weeks, and after 12 weeks. MAIN OUTCOME MEASURES Dietary intakes, blood lipids, dry body weight, serum albumin, and serum C-reactive protein comprised our main outcome measures. RESULTS According to a per-protocol analysis of 14 study completers, fat supplementation resulted in significantly increased total energy intake (+1.6 MJ/day, or 380kcal/day) and an increased dietary fat energy percentage (+9%). We observed no significant changes in blood lipids. Dry body weight (+0.49kg, P=.04) increased, and serum C-reactive protein concentration fell (-1.69mg/L, P=.01), with fat supplementation. Intention-to-treat analysis of 39 participants confirmed the absence of adverse blood-lipid changes. CONCLUSIONS Unsaturated fat supplementation increased total dietary energy intake to recommended levels, had no adverse impact on blood lipids, improved nutritional status as assessed according to dry body weight, and reduced systemic inflammation as assessed according to C-reactive protein serum concentrations. Adding unsaturated fat to the diet seems to be a safe and effective way to prevent and treat malnutrition in hemodialysis patients.

Abstract
The incidence of chronic kidney disease (CKD) in the U.S. continues to increase, and now over 10% of the U.S. population has some form of CKD. Although some patients with CKD will ultimately develop renal failure, most patients with CKD will die of cardiovascular disease before dialysis becomes necessary. Patients with CKD have major proatherogenic lipid abnormalities that are treatable with readily available therapies. The severe derangements seen in lipoprotein metabolism in patients with CKD typically results in high triglycerides and low high-density lipoprotein (HDL) cholesterol. Because of the prevalence of triglyceride disorders in patients with CKD, after treating patients to a low-density lipoprotein goal, non-HDL should be calculated and used as the secondary goal of treatment. A review of the evidence from subgroup analysis of several landmark lipid-lowering trials supports treating dyslipidemia in mild to moderate CKD patients with HMG-CoA reductase inhibitors. The evidence to support treating dyslipidemia in hemodialysis patients, however, has been mixed, with several outcome trials pending. Patients with CKD frequently have mixed dyslipidemia and often require treatment with multiple lipid-lowering drugs. Although statins are the cornerstone of therapy for most patients with CKD, differences in their pharmacokinetic properties give some statins a safety advantage in patients with advanced CKD. Although most other lipid-lowering agents can be used safely with statins in combination therapy in patients with CKD, the fibrates are renally metabolized and require both adjustments in dose and very careful monitoring due to the increased risk of rhabdomyolysis. After reviewing the safety and dose alterations required in managing dyslipidemia in patients with CKD, a practical treatment algorithm is proposed.

Abstract
To measure the long-term changes in weight and plasma lipids after switching antipsychotic treatment to ziprasidone, three 52-week, open-label extension studies of ziprasidone in outpatients (N=185) with schizophrenia or schizoaffective disorder successfully completing one of three, 6-week switch studies were carried out. Pre-switch treatment consisted of risperidone (n=43), olanzapine (n=71), or conventional antipsychotic agents (n=71). The maximum length of exposure to ziprasidone was 58 weeks. Nonfasting total cholesterol and triglyceride levels were obtained at baseline and at weeks 6, 19, 32, 45, and 58. Weight was measured at baseline and during each follow-up visit; height was recorded at baseline for the purpose of body mass index (BMI) calculation. Efficacy measures included the Positive and Negative Syndrome Scale and Clinical Global Impression-Severity scale which were obtained at baseline and major follow-up points. Clinically significant sustained improvements in weight, BMI, total cholesterol, and triglyceride levels were observed among patients switched to ziprasidone from risperidone or olanzapine. Switching from conventional antipsychotics was not associated with significant changes in weight and lipid parameters. Mean reductions in weight from baseline to study endpoint were 9.8 kg (p<0.001) and 6.9 kg (p<0.005) for patients previously treated with olanzapine and risperidone, respectively. These findings demonstrate that switching from risperidone or olanzapine to ziprasidone is associated with sustained, clinically significant improvements in weight and plasma lipids.

Abstract
BACKGROUND The objective of this study was to establish a prospective population-based cohort to investigate the prevalence, incidence and risk factors for mild cognitive impairment (MCI) and dementia. METHODS The Olmsted County, Minn., population, aged 70-89 years on October 1, 2004, was enumerated using the Rochester Epidemiology Project. Eligible subjects were randomly selected and invited to participate. Participants underwent a comprehensive in-person evaluation including the Clinical Dementia Rating Scale, a neurological evaluation and neuropsychological testing. A consensus diagnosis of normal cognition, MCI or dementia was made by a panel using previously published criteria. A subsample of subjects was studied via telephone interview. RESULTS Four hundred and two subjects with dementia were identified from a detailed review of their medical records but were not contacted. At baseline, we successfully evaluated 703 women aged 70-79 years, 769 women aged 80-89 years, 730 men aged 70-79 years and 517 men aged 80-89 years (total n = 2,719). Among the participants, 2,050 subjects were evaluated in person and 669 via telephone. CONCLUSIONS Strengths of the study are that the subjects were randomly selected from a defined population, the majority of the subjects were examined in person, and MCI was defined using published criteria. Here, we report the design and sampling, participation, baseline measures and sample characteristics.

Abstract
Serum levels of lipids and lipoproteins were determined in 98 post-renal transplant fasting patients, and lipids and non-high density lipoprotein-cholesterol (non-HDL-C) and lipid ratios in the same post-renal transplant non-fasting patients were compared. The reference group was 87 healthy subjects. All patients were divided into two groups: patients with dyslipidemia (n = 69) and patients with normolipidemic (n = 29). The post-renal transplant patients (TX) with dyslipidemia had a significantly increased concentration of triglyceride (TG), low-density lipoprotein-cholesterol (LDL-C), non-HDL-C, apoB, and TRL and lipid ratios, and decreased HDL-C level and lipoprotein ratios. The lipids, lipoproteins, and lipoprotein ratios were significantly beneficial in TX patients with normolipidemic than in those with dyslipidemia. However, TRL concentration and lipid ratios were significantly increased and apoAI/apoCIII significantly decreased as compared to the reference group. The TX patients with dyslipidemia showed a significant correlation between TG and apoB:CIII (r = 0.562, p < 0.001) and apoCIII (r = 0.380, p < 0.004), but those with normolipidemic showed a significant correlation only between TG and apoCIII (r = 0.564, p < 0.008). Regression and Bland-Altman analyses showed excellent correlation between fasting and nonfasting non-HDL-C levels (r = 0.987, R(2) + 0.987) in TX patients both with dyslipidemia and normolipidemic. We think the finding that nonfasting labs that are reliable for non-HDL-C as well as total cholesterol is important, as fasting labs are not always available. Disturbances of lipids, lipoproteins, and TRLs depend not only on the kind of treatment, but due to multiple factors can accelerate cardiovascular complications in post-renal transplant patients with dyslipidemia and also with normolipidemic. Further studies concerning this problem should be completed.

Abstract
OBJECTIVE To present the effects of a relatively modest environmental intervention on biological cardiovascular risk indicators. METHOD A controlled trial, including two worksites. Measurements (i.e., body composition, blood pressure and serum cholesterol) took place at baseline and at 3- and 12-month follow-up. The 12-month environmental intervention (The Hague, The Netherlands, 2004) consisted of: a 'Food'-part: to stimulate healthier food choices by means of product information in the canteen, and a 'Steps'-part: focused on stimulating stair use by means of motivational prompts in staircases and on elevator doors. RESULTS Significant differences in change between groups (n=540) in favor of the intervention group were found on: [1] total cholesterol for women (-0.35 mmol/l); [2] HDL for men at 3 months (0.05 mmol/l) and 12 months (0.10 mmol/l); and [3] the total-HDL ratio for the total intervention group at 3 and 12 months (-0.45 mmol/l). Both groups showed a decrease in all body composition values at both follow-ups. A significant difference in change in systolic BP was found in favor of the control group (approximately 4 mm Hg), due to an increase in the intervention group at both follow-ups. CONCLUSIONS Based on the contrasting results, this modest environmental intervention was ineffective in reducing cardiovascular risk in a population of office workers.

Abstract
Aortic pulse wave velocity (Ao-PWV) and ankle-brachial blood pressure index (ABPI) are significant prognostic factors in patients with end-stage renal disease (ESRD). Diabetes mellitus (DM) promotes changes in arterial walls, including marked increases in Ao-PWV and decreases in ABPI. To determine the prevalence of peripheral arterial occlusive disease (PAOD) as well as the clinical variables useful in predicting these changes in nondiabetic patients with ESRD undergoing hemodialysis (HD), we performed a cross-sectional study in a cohort of 143 patients. Ao-PWV and ABPI were measured simultaneously and compared with several annual biochemical measurements and other clinical variables. The prevalence of PAOD in our cohort was 30.5%. In univariate regression analysis, Ao-PWV correlated positively with age, heart rate (HR), blood pressure (BP), pulse pressure (PP) and HbA1c, and negatively with serum albumin and ABPI. ABPI correlated negatively with age, HD duration, systolic BP, PP, low-density lipoprotein (LDL) cholesterol and hypersensitive C-reactive protein (hs-CRP), and positively with serum albumin and bone mineral density. In a step-down multiple regression analysis, HbA1c was identified as an independent determinant of Ao-PWV along with age, HD duration, HR and mean BP, while hs-CRP was an independent contributor to ABPI along with age, HD duration, PP and LDL cholesterol. Our results suggest that HD promotes aortic wall stiffness and PAOD progression. We recommend the monitoring of HbA1c to allow the prediction of aortic wall stiffness in nondiabetic ESRD patients. Our results did not confirm the influence of insulin resistance on the development of arterial sclerosis lesions.
