Abstract
The World elderly population is expected to double before 2050. Unhealthy habits and unhealthy lifestyles are commonly associated with age-related diseases or their worsening. Modification in daily lifestyle and diet may help preventing age-related diseases onset and efficiently affecting their evolution, thus promoting the Healthy Aging process, concept recently coined to describe the disease-free aging process. This review highlights the role of nutrition science in promoting healthy aging. Since the Mediterranean Model demonstrated to be a useful style in supporting healthy aging, promotion of this correct lifestyle by health policies seems to be the best approach to achieve this target.

Health Risk, Functional Markers and Cognitive Status in Institutionalized Older Adults: A Longitudinal Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17197303.

Abstract
A Follow-up of vitamin B12 and lipids status is essential in older people, being closely related to non-communicable diseases. Their relationships with cognitive and physical status are not clear. The aim was to analyze the evolution of vitamin B12 and related parameters, lipid and hematological profiles, and their relationships with cognitive and physical status among institutionalized elderly. Sixty residents, ranged from 62 to 99, were evaluated. Biomarkers (vitamin B12 and related parameters, lipid and hematological profiles), functional capacity (handgrip, arm and leg strength), and cognitive status (Mini-Mental State Examination) were evaluated four times at 4-month intervals. At the beginning of the study, 63% and 70% of the sample showed abnormal homocysteine and folate values, respectively. At the end of the year, abnormal homocysteine increased to 68%, abnormal folate values decreased to 50%. Throughout the year, serum folate showed a significant increase (14.9 vs. 16.3 nmol/L), (p < 0.05). Serum cobalamin (299 vs. 273 pmol/L). HDL-cholesterol (49.9 vs. 47.0 mg/dL) and triglyceride levels (102.4 vs. 123.2 mg/dL) showed a significant decrease and increase respectively in mean values (all p < 0.05). Serum cobalamin and HDL-cholesterol were the most important biomarkers associated with cognitive function (both p < 0.05). The most relevant biomarkers associated with poor physical strength depending on the body part analyzed were low concentrations of HDL-cholesterol, LDL-cholesterol, apolipoprotein A1, and albumin (all p < 0.05). The evolution of lipid biomarkers, their significance with cognitive values, and association with handgrip, point to the importance of the handgrip measurement, a very simple test, as an important health marker. Both serum albumin and physical strength are important health markers in older people.

Gene discovery for high-density lipoprotein cholesterol level change over time in prospective family studies. Atherosclerosis 2020; 297:102-110. [PMID: 32109663 DOI: 10.1016/j.atherosclerosis.2020.02.005] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2019] [Revised: 01/16/2020] [Accepted: 02/12/2020] [Indexed: 01/14/2023]
Abstract
BACKGROUNDS AND AIMS Several genes are known to contribute to the levels and metabolism of HDL-C, however, their protective effects in cardiovascular disease (CVD), healthy aging, and longevity are complex and poorly understood. It is also unclear if these genes predict longitudinal HDL-C change. We aimed to identify loci influencing HDL-C change. METHODS We performed a genome-wide association study (GWAS) with harmonized HDL-C and imputed genotype in three family-based studies recruited for exceptional survival (Long Life Family Study), from community-based (Framingham Heart Study) and enriched for CVD (Family Heart Study). In 7738 individuals with at least 2 visits, we employed a growth curve model to estimate the random linear trajectory parameter of age-sex-adjusted HDL-C for each person. GWAS was performed using a linear regression model on HDL-C change accounting for kinship correlations, population structure, and differences among studies. RESULTS We identified a novel association for HDL-C with GRID1 (p = 5.43 × 10-10), which encodes a glutamate receptor channel subunit involved in synaptic plasticity. Seven suggestive novel loci (p < 1.0 × 10-6; MBOAT2, LINC01876-NR4A2, NTNG2, CYSLTR2, SYNE2, CTXND1-LINC01314, and CYYR1) and a known lipid gene (ABCA10) showed associations with HDL-C change. Two additional sex-specific suggestive loci were identified in women (DCLK2 and KCNJ2). Several of these genetic variants are associated with lipid-related conditions influencing cardiovascular and metabolic health, have predictive regulatory function, and are involved in lipid-related pathways. CONCLUSIONS Modeling longitudinal HDL-C in prospective studies, with differences in healthy aging, longevity and CVD risk, contributed to gene discovery and provided insights into mechanisms of HDL-C regulation.

Abstract
Familial longevity is characterized by beneficial metabolic phenotype in lipid metabolism and APOE genetic variation. Although effects of lipid metabolism and the genetic basis for human longevity remain largely unclear, the contribution of high-density lipoprotein cholesterol (HDL-C) and APOE ε2 allele has been repeatedly demonstrated. This study was designed to determine whether ApoE isoforms and HDL-C levels marked the familial longevity status in an offspring cohort with the age range of 20-89 years old and subsequently to explore the correlation between these two markers and the aging. In the Bama Aging Study (BAS), we recruited 312 offspring from longevity historical families and 298 controls from non-longevity historical families. Information on APOE genotype frequencies, lipid levels, and population characteristics were recorded. No evidence was found to support the association of APOE genotypes with HDL-C and age. HDL-C was significantly higher in longevity group (p < 0.0001). Scatter plot showed a moderately strong linear relationship between the HDL-C level and age in longevity group (r = 0.213, p < 0.001). We conclude that the variation of the APOE gene may not influence familial longevity status at a certain age but the moderate-high HDL-C level contributes to the familial longevity in Bama.

Abstract
OBJECTIVE The development of these guidelines is mandated by the American Association of Clinical Endocrinologists (AACE) Board of Directors and American College of Endocrinology (ACE) Board of Trustees and adheres with published AACE protocols for the standardized production of clinical practice guidelines (CPGs). METHODS Recommendations are based on diligent reviews of the clinical evidence with transparent incorporation of subjective factors, according to established AACE/ACE guidelines for guidelines protocols. RESULTS The Executive Summary of this document contains 87 recommendations of which 45 are Grade A (51.7%), 18 are Grade B (20.7%), 15 are Grade C (17.2%), and 9 (10.3%) are Grade D. These detailed, evidence-based recommendations allow for nuance-based clinical decision-making that addresses multiple aspects of real-world medical care. The evidence base presented in the subsequent Appendix provides relevant supporting information for Executive Summary Recommendations. This update contains 695 citations of which 203 (29.2 %) are EL 1 (strong), 137 (19.7%) are EL 2 (intermediate), 119 (17.1%) are EL 3 (weak), and 236 (34.0%) are EL 4 (no clinical evidence). CONCLUSION This CPG is a practical tool that endocrinologists, other health care professionals, health-related organizations, and regulatory bodies can use to reduce the risks and consequences of dyslipidemia. It provides guidance on screening, risk assessment, and treatment recommendations for a range of individuals with various lipid disorders. The recommendations emphasize the importance of treating low-density lipoprotein cholesterol (LDL-C) in some individuals to lower goals than previously endorsed and support the measurement of coronary artery calcium scores and inflammatory markers to help stratify risk. Special consideration is given to individuals with diabetes, familial hypercholesterolemia, women, and youth with dyslipidemia. Both clinical and cost-effectiveness data are provided to support treatment decisions.

Abstract
Pharmacological interventions to increase the concentration of high-density lipoprotein (HDL) have led to disappointing results and have contributed to the emergence of the concept of HDL functionality. The anti-atherogenic activity of HDLs can be explained by their functionality or quality. The capacity of HDLs to maintain cellular cholesterol homeostasis and to transport cholesterol from peripheral cells to the liver for elimination is one of their principal anti-atherogenic activities. However, HDLs possess several other attributes that contribute to their protective effect against cardiovascular diseases. HDL functionality is regulated by various proteins and lipids making up HDL particles. However, several studies investigated the role of paraoxonase 1 (PON1) and suggest a significant role of this protein in the regulation of the functionality of HDLs. Moreover, research on PON1 attracted much interest following several studies indicating that it is involved in cardiovascular protection. However, the mechanisms by which PON1 exerts these effects remain to be elucidated.

Abstract
BACKGROUND In several observational and clinical studies, the association between serum cholesterol levels and cancer is still unsettled although serum total cholesterol has been associated with increased mortality from cancer. Moreover, the importance of abnormal levels of serum lipid components as the main features of dyslipidemia and the risk of individual cancers is unclear. The prevalence of dyslipidemia is increasing worldwide but, the precise aetiology of the link between risk of cancer and the behaviour of lipid profile, prior diagnosis, has yet to be determinated. Low levels of high-density lipoprotein cholesterol (HDL) at baseline of many of the studies analyzed has to be taken into account, and continued low levels of HDL without explanation should be considered by clinicians. AIMS The main aim of this review was to undertake the assessment of the most recent studies implying the lipid profile and cancer risk, and focused on low HDL levels at baseline and follow up, and also analyzing this behaviour on the different cancer types. MATERIAL AND METHODS A literature search was performed to identify publications. The most recent prospective and case-control studies with multivariate Cox models were analyzed and also were considered some recent meta-analyses. RESULTS AND CONCLUSIONS The findings exposed in this review suggest that the association with low HDL levels at baseline of different studies of cancer risk is shared among many types of cancer, and it is mainly linked to obesity and inflammation, suggesting a common pathway.

Abstract
The Black Swan Theory was described by Nassim Nicholas Taleb in his book “The Black Swan”. This theory refers to “high-impact, hard-to-predict, and rare events beyond the realm of normal expectations”. According to Taleb’s criteria, a Black Swan Event is a surprise, it has a major impact and after the fact, the event is rationalized by hindsight, as if it had been expected. For most of human history centenarians were a rare and unpredictable phenomenon. The improvements of the social-environmental conditions, of medical care, and the quality of life caused a general improvement of the health status of the population and a consequent reduction of the overall morbidity and mortality, resulting in an overall increase of life expectancy. The study of centenarians and supercentenarians had the objective to consider this black swan and to evaluate the health, welfare, social and economic consequences of this phenomenon.

Abstract
BACKGROUND C-reactive protein (CRP) and high-density lipoprotein (HDL) cholesterol are well-known cardiovascular predictors. However, the joint effect of these parameters on long-term mortality has not been established. METHODS We studied a total of 92,500 subjects older than 20 years who underwent routine health examination at the three health care centers affiliated with Seoul National University. High-sensitivity CRP and the lipid profile were obtained at baseline. Subjects were followed for a median of 45.5 months. Mortality data were obtained from the National Statistics Office of Korea. RESULTS There were 649 deaths (0.7%) during the follow-up. The leading cause of death was cancer. The subjects who died were significantly older, had a male predominance, and had increased levels of inflammatory markers. A significant mortality difference was identified according to the CRP and HDL cholesterol levels. Considering both parameters jointly, subjects with a CRP ≥1.4 mg/L (highest quartile) and HDL cholesterol <45 mg/dL (lowest quartile) were at the highest risk for all-cause mortality, even after adjusting for covariates (hazard ratio 2.29, 95% confidence interval, 1.83~2.87). After matching on the propensity score, 6304 subjects with a high CRP and low HDL cholesterol were at high risk of death (hazard ratio 2.52, 95% confidence interval, 1.59~4.01). Interestingly, the joint effect of CRP and HDL cholesterol was observed for cardiovascular as well as cancer-related mortality prediction. CONCLUSIONS Elevated CRP and low HDL cholesterol jointly contribute to the prediction of all-cause, cancer, and cardiovascular mortality in Koreans. The interactive relationship between them in mediating inflammatory processes might explain these results.

Abstract
BACKGROUND In cross-sectional and some cohort studies with shorter follow-up, high-density lipoprotein cholesterol (HDL-C) has been associated with longer life. We sought to examine the relationship between HDL-C and death before age 90 in the Physicians' Health Study (PHS). METHODS AND RESULTS Of PHS enrollees who had blood collected at PHS II baseline (approximately 1997), we selected 1351 men old enough to reach age 90 by March 4, 2009, and with complete data on HDL-C and total cholesterol, lifestyle factors, and comorbidities. We used Cox proportional hazards to determine the hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause, cardiovascular disease (CVD), and non-CVD mortality before age 90, adjusting for potential confounders. After a mean (SD) follow-up of 6.8 (3.2) years, 44.1% of men in the lowest baseline HDL-C quartile (<32.8 mg/dL) compared with 32.9% (11.2% absolute risk reduction) in the highest HDL-C quartile (≥ 54.1 mg/dL) died before age 90. In multivariable adjusted analyses, men in the highest HDL-C quartile had a 28% lower risk (HR, 0.72; 95% CI, 0.55 to 0.94) of death before age 90 compared with men in the lowest HDL-C quartile. In age-adjusted analyses, increasing baseline HDL-C was significantly associated with a lower risk of CVD death. No association was found between HDL-C and non-CVD mortality. CONCLUSION In male physicians, higher baseline HDL-C levels were associated with a lower risk of all-cause and CVD mortality before age 90.

Abstract
BACKGROUND TaqIB polymorphism in the cholesteryl ester transfer protein (CETP) gene has been reported to be associated with serum high-density lipoprotein cholesterol (HDL-C) levels and longevity in several populations, but controversial results also arose probably due to racial/ethnic diversity. Bama is a remote and mountainous county located in the northwest of Guangxi, People's Republic of China, which has been well known for its longevity for centuries. The current study was to investigate the possible association of CETP TaqIB polymorphism with serum lipid levels and longevity in the Bama Zhuang population. METHODS The CETP TaqIB genotypes were determined by polymerase chain reaction and restriction fragment length polymorphism in 523 long-lived inhabitants (long-lived group, LG; aged 90-107 years) and 498 healthy controls without longevity family history (non-long-lived group, non-LG; aged 40-69 years) residing in Bama County. RESULTS The levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were higher but TG, HDL-C/LDL-C ratio and the prevalence of dyslipidemia were lower in LG than in non-LG (P < 0.001 for all). There were no differences in the allelic and genotypic frequencies between the two groups (P > 0.05). Serum HDL-C levels and HDL-C/LDL-C ratio in LG were different among the genotypes (P < 0.01 for each), the subjects with B2B2 and B1B2 genotyes had higher HDL-C levels and HDL-C/LDL-C ratio than the subjects with B1B1genotye, whereas the levels of TC and HDL-C in non-LG were different among/between the genotypes (P < 0.01 for each), the B2 allele carriers had lower TC and higher HDL-C levels than the B2 allele noncarriers. Serum TG and HDL-C levels and HDL-C/LDL-C ratio were correlated with genotypes in LG, whereas serum TC and HDL-C levels were associated with genotypes in non-LG (P < 0.05-0.001). CONCLUSIONS The association of CETP TaqIB polymorphism and serum lipid profiles is different between LG and non-LG in the Chinese Bama Zhuang population. CETP TaqIB polymorphism might be one of the longevity-related genetic factors in this population.

Abstract
OBJECTIVES To identify high-density lipoprotein (HDL) subfractions associated with longevity in men. DESIGN Fifty-three-year prospective follow-up of Gofman's Livermore Cohort between 1954 and 2008. SETTING Lawrence Livermore National Laboratory. PARTICIPANTS One thousand one hundred forty-four men who consented to the study, had analytic ultracentrifuge measurements of lipoprotein subfractions at baseline, and were old enough at baseline to have survived to age 85 during follow-up. MEASUREMENTS Survival was determined according to participant contact, Social Security Death Index, and National Death Index. RESULTS Three hundred ninety men survived to 85 years old (34.1%). Survivors were less likely than nonsurvivors to be in the lowest HDL3 (% (standard error) 18.5% (2.0%) vs 27.3% (1.6%), P < .001) and HDL2 (22.1% (2.1%) vs 27.7% (1.6%), P = .04) quartiles. Logistic regression analyses showed that the lowest HDL3 quartile significantly predicted shorter longevity (P = .002), whereas the linear increases per mg/dL of HDL3 did not (P = .38), suggesting a risk threshold proximal to the 25th percentile. Men who were above the 25th HDL3 percentile had 70% greater odds of surviving until age 85 than those below this level, which persisted when adjusted for HDL2, very low-density lipoprotein (LDL), and standard risk factors. Proportional hazard analyses of survival before age 85 showed that being in the lowest HDL3 quartile increased age-adjusted cancer risk by 39% (P = .05) and noncancer risk by 23% (P = .04) when adjusted for other risk factors. Survivors also smoked less (mean ± SD 0.31 ± 0.48 vs 0.57 ± 0.56 packs/d, P < .001), had lower systolic (118.36 ± 11.08 vs 122.81 ± 13.55 mmHg, P < .001) and diastolic (70.61 ± 8.59 vs 73.14 ± 9.22 mmHg, P < .001) blood pressures and lower LDL mass (359.55 ± 80.42 vs 374.37 ± 86.10 mg/dL, P = .009) and total cholesterol concentrations (229.51 ± 43.21 vs 235.89 ± 45.40 mg/dL, P = .04) than nonsurvivors. CONCLUSION Low HDL3 reduces the odds of extended survival in men, independent of HDL2, other lipoproteins, and standard risk factors.

Abstract
No previous researchers have sought to determine whether high-density lipoprotein (HDL) cholesterol levels are associated with survival to 85 years of age in a prospective cohort of aging men. We selected 652 men (mean age 65 years) enrolled in the VA Normative Aging Study who had ≥ 1 HDL cholesterol level documented during the study and who were old enough on the date of HDL cholesterol measurement to reach 85 years of age by the end of follow-up (July 1, 2008). We categorized initial HDL cholesterol into < 40 mg/dl (reference group), 40 to 49 mg/dl, or ≥ 50 mg/dl. Information on co-morbidities, lifestyle factors, measured lipid parameters, and medications were collected during triennial visits. We used proportional hazards to determine hazard ratios (HRs) for mortality before age 85 years for each category of initial HDL cholesterol compared to the reference adjusting for co-morbidities, calculated low-density lipoprotein cholesterol, medications, smoking, body mass index, and alcohol consumption. Treating HDL cholesterol as a continuous predictor, we also determined the HR for each 10-mg/dl increment in HDL cholesterol. Fully adjusted HR (95% confidence interval) for survival to 85 years of age for participants with an initial HDL cholesterol level ≥ 50 mg/dl compared to the reference was 0.72 (0.53 to 0.98). Each 10-mg/dl increment in HDL cholesterol was associated with a 14% (HR 0.86, 0.78 to 0.96) decrease in risk of mortality before 85 years of age. In conclusion, after adjusting for other factors associated with longevity, higher HDL cholesterol levels were significantly associated with survival to 85 years of age.

Abstract
Many theories aim at explaining the mechanisms of aging and death in humans. Decreased levels of androgens, growth hormone, and insulin-like growth factor accompany natural aging in men. Androgens influence the growth and maturation of men in various stages of their life. The action of androgens is performed by binding or not binding to androgen receptors. However, various actions of androgens were clarified after the discovery and genotyping of the androgen receptor. The influence of androgens on the lipid profile was reported by several researchers. This negative influence of androgens in men and the positive influence of estrogens in women are responsible for the higher impact of atherogenesis in men compared with women. In aging men, this negative influence of androgens on the lipid profile is more pronounced. This review considers the influence of age on lipid metabolism in men.

Abstract
Purpose: High levels of high density lipoprotein (HDL) cholesterol are associated with a decreased risk of coronary heart disease (CHD). Subjects with high levels of HDL cholesterol (>70 mg/dl; 1.79 mmol/l) as well as high levels of low density lipoprotein (LDL) cholesterol, could represent a group with longevity syndrome (LS). Since HDL particles are influenced by cholesteryl ester transfer protein (CETP) activity, it is worth studying the CETP polymorphism. The aim of the study was to detect whether 2 genetic variants of the CETP are associated with the LS. Subjects and Methods: The study population consisted of 136 unrelated men and women with no personal and family history of CHD; 69 met the criteria for LS and 67 did not meet these criteria and had “normal” HDL cholesterol (>40 and <70 mg/dl; >1.03 and <1.79 mmol/l). All patients were genotyped for the TaqIB and I405V polymorphisms. Results: The B2 allele frequency of TaqIB polymorphism was higher in the LS in comparison with the non-LS group (p=0.03) whereas B1 allele frequency was higher in the non-LS group (p=0.03). Conclusions: Gene polymorphisms could help decide whether individuals who have increased levels of both LDL cholesterol and HDL cholesterol require treatment. Some of the prerequisites could include that subjects with LS should not only have very high levels of HDL cholesterol but also favorable gene polymorphisms. However, further investigations with a larger sample and including other gene polymorphisms, are needed.

Abstract
High-density lipoprotein (HDL) particles exhibit multiple antiatherogenic effects. They are key players in the reverse cholesterol transport which shuttles cholesterol from peripheral cells (e.g. macrophages) to the liver or other tissues. This complex process is thought to represent the basis for the antiatherogenic properties of HDL particles. The amount of cholesterol transported in HDL particles is measured as HDL cholesterol (HDLC) and is inversely correlated with the risk for coronary artery disease: an increase of 1mg/dL of HDLC levels is associated with a 2% and 3% decrease of the risk for coronary artery disease in men and women, respectively. Genetically determined conditions with high HDLC levels (e.g. familial hyperalphalipoproteinemia) often coexist with longevity, and higher HDLC levels were found among healthy elderly individuals. HDLC levels are under considerable genetic control with heritability estimates of up to 80%. The identification and characterization of genetic variants associated with HDLC concentrations can provide new insights into the background of longevity. This review provides an extended overview on the current genetic-epidemiological evidence from association studies on genes involved in HDLC metabolism. It provides a path through the jungle of association studies which are sometimes confusing due to the varying and sometimes erroneous names of genetic variants, positions and directions of associations. Furthermore, it reviews the recent findings from genome-wide association studies which have identified new genes influencing HDLC levels. The yet identified genes together explain only a small amount of less than 10% of the HDLC variance, which leaves an enormous room for further yet to be identified genetic variants. This might be accomplished by large population-based genome-wide meta-analyses and by deep-sequencing approaches on the identified genes. The resulting findings will probably result in a re-drawing and extension of the involved metabolic pathways of HDLC metabolism.

Abstract
We investigated the association between superoxide dismutase (SOD) Ala16Val polymorphism and the levels of oxidized LDL lipoprotein-C (ox-LDL-C) in two age-different Greek cohorts. Four hundred fifteen middle-aged (n=147 females: 43.2+/-13 years, n=268 males: 43.3+/-14 years) Caucasian Greek subjects consisted the middle aged cohort. One hundred seventy five elderly (n=88 females: 79.9+/-4 years; n=87 males: 80.6+/-4 years) were selected from the elderly cohort. Genotype data were obtained for all of them. Multiple linear regression analysis, stratified by gender and adjusted for age, smoking habits and body mass index as covariates, showed higher ox-LDL-C levels for the middle aged men with the Val/Val genotype, compared to the other allele (Ala/Ala and Ala/Val) carriers (65.9+/-25.7 vs. 55.7+/-20.5 mg/dl; standardized beta coefficient=0.192, P=0.012). On the contrary, elderly women with the Val/Val genotype occurred with lower ox-LDL-C levels compared to the Ala/Ala or Ala/Val genotype (74.2+/-22.1 vs. 86.5+/-26.6 mg/dl; standardized beta coefficient= -0.269, P=0.015). The same trend was also recorded in elderly men, however without reaching statistical significance (standardized beta coefficient= -0.187, P=0.077). Moreover, elderly men and women with the Ala/Ala or Ala/Val genotype presented higher triglycerides levels compared to Val/Val (women: 145.2+/-68.7 vs. 114.3+/- 34.3 mg/dl, P= 0.027; men: 147.8+/-72.4 vs. 103.7 +/-38.0 mg/dl, P=0.002). Additionally, middle aged men with the Val/Val genotype had higher HDL-C levels compared to the Ala allele carriers. The results suggest that SOD Ala16Val polymorphism is an age-dependent modulator of ox-LDL-C levels in middle-aged men and elderly women.

Abstract
BACKGROUND AND AIMS Aging is associated with an increased risk of developing atherosclerosis. Subjects over 80 years of age without cardiovascular disease provide a model to investigate the protective factors increasing their resistance to atherosclerotic disease. Platelet-activating factor acetylhydrolase (PAF-AH) is an enzyme associated with low density lipoprotein (LDL) and high density lipoprotein (HDL) inactivating platelet-activating factor (PAF) and preventing LDL oxidation by hydrolysis of oxidized phospholipids. The aim of the present study was to evaluate the contribution of the PAFAH gene Arg92His, Ile198Thr and Ala379Val polymorphisms to resistance toward developing cardiovascular events in healthy Sicilian octogenarians. METHODS Distribution of PAF-AH genotypes and activity, and biochemical parameters, were compared between 100 octogenarians and 200 healthy adults. RESULTS The individuals in the elderly group displayed significantly higher levels of HDL-C (p<0.001) and plasma (p<0.001) and HDL (p<0.001) PAF-AH activity. Analysis of PAFAH genotype distributions showed no significant differences between octogenarians and controls. No differences among PAF-AH genotypes with respect to plasma and HDL PAF-AH activity were found in either group. CONCLUSIONS Our results provide no evidence of a significant association between the PAF-AH gene Arg92His, Ile198Thr and Ala379Val polymorphisms and successful aging in Sicilians. They also emphasize that, in these subjects, aging is characterized by increased levels of PAF-AH activity and HDL-C.

Abstract
The relationships among lipoprotein metabolism, genetic vascular factors, vascular disease, and Alzheimer's disease suggest that the examination of centenarian populations in relation to certain genes or lipoprotein metabolism provide insights into human longevity. The findings on the higher frequency of the apolipoprotein E epsilon4 allele in middle-aged subjects than in centenarians were substantially confirmed. On the contrary, recent findings did not confirm previous data on increased prevalence of the high-risk angiotensin I converting enzyme D allele in French centenarians. The variability in the strength of association between angiotensin I converting enzyme polymorphism and longevity could be related to regional differences in angiotensin I converting enzyme D allele frequency in Europe recently showed, as also recently reported for apolipoprotein Eepsilon2 and epsilon4 allele in centenarians. Indeed some studies of lipoprotein profiles in centenarians have also had contradictory outcomes, with evidence of lower serum levels of high-density lipoprotein cholesterol, with higher high-density lipoprotein 2 cholesterol subfraction, larger high-density lipoprotein and low-density lipoprotein particle sizes, and higher lipoprotein(a) concentration in centenarians, which is apparently disadvantageous for human longevity. Elevated lipoprotein(a) serum levels, increasing the risk for cerebrovascular disease, may play a role in determining clinical Alzheimer's disease, but lipoprotein(a) elevation in centenarians, in the absence of other coronary artery disease risk factors, appears as a positive survival factor. In different populations, there are significant trends in the reduction of serum apolipoprotein E levels from apolipoprotein E epsilon2- to epsilon4-carriers and significant differences in serum apolipoprotein E levels with respect to age in epsilon4-carriers but only after adjustment for high-density lipoprotein cholesterol. While further studies are needed to confirm the possible role of apolipoprotein E concentration as putative longevity factor this paper provides an overview of many of the investigated vascular factors with respect to longevity.

Abstract
BACKGROUND High-density lipoprotein (HDL) cholesterol has been hypothesised to be a reliable marker of frailty and poor prognosis among the oldest elderly. We evaluate the relationship of HDL-cholesterol with measures of physical performance, muscle strength, and functional status in older persons aged 80years or older. METHODS Data are from baseline evaluation of the ageing and longevity study in the Sirente geographic area (ilSIRENTE study) (n = 364). Physical performance was assessed using the physical performance battery score [short physical performance battery (SPPB)], which is based on three-timed tests: 4-m walking-speed, balance, and chair-stand tests. Muscle strength was measured by hand-grip strength. Analyses of covariance were performed to evaluate the relationship of different HDL-cholesterol levels with physical function. RESULTS In the unadjusted analyses, physical function (as measured by the 4-m walking-speed, theSPPB score, the basic and instrumental activities of daily living scales scores), but not hand-grip strength, improved significantly as HDL-cholesterol tertiles increased. After adjustment for potential confounders, which included age, gender, living alone, alcohol abuse, physical activity, congestive heart failure, diabetes, cerebrovascular diseases, osteoarthritis, albumin, urea, C-reactive protein and LDL cholesterol, the association of HDL-cholesterol tertiles with the 4-m walking-speed and the SPPB score was still consistent. CONCLUSION The present study suggests that among very old subjects living in the community the higher levels of HDL-cholesterol are associated with better functional performance.

Abstract
As the elderly population is increasing rapidly, there is a lot of scientific interest in clarifying the differential life-style, genetic, biochemical and molecular factors contributing to mortality or exceptional longevity. Within the framework of the ZINCAGE project, 249 old (60-85 years) and nonagenarian Greek subjects (>/=85 years old) were recruited and anthropometrical, blood and biochemical indices as well as blood pressure measurements were obtained. Based upon the inclusion criteria, 214 of them were characterized as healthy (136 female, 78 male), while those characterized as non-healthy were excluded from the statistical analysis. The findings indicated an 88.4% prevalence of overweight and obesity in elderly (91.2% in women, 83.3% in men), while a significant decrease in body mass index with age was recorded. Hypercholesterolemia was observed in 75.3% of elderly women and in 69.2% of men. Erythrocyte sedimentation rate value was increased in 27.6% of all healthy elderly, while zinc deficiency was observed in 18.7% of elderly. Over 85.0% of all healthy elderly were within normal range for all other hematological analysis. Blood analysis confirmed the good health status of the elderly recruited as healthy, except for the high prevalence of obesity and hypercholesterolemia.

Abstract
BACKGROUND Several groups of patients at high risk for cardiovascular disease have been found to show an exaggerated postprandial hypertriglyceridemia. Postprandial lipemia (PPL) therefore has been implicated as a potential additional risk factor that has been evading us. The purpose of this study was to test the effect of high fasting high-density lipoprotein cholesterol (HDL-C) levels on PPL in postmenopausal females. METHODS Oral fat tolerance test, as quantified by the areas under the curve (AUC) of triglyceride (TG) levels, was given to 3 groups: normal postmenopausal females (control), postmenopausal females with exceptionally high HDL-C and a familial history of longevity (longevity syndrome), and postmenopausal females that were heterozygotes of familial hypercholesterolemia (hFH) with exceptionally high HDL-C. RESULTS The PPL was not different between the control and longevity syndrome groups but was significantly higher in the hFH group; AUC (SD), in mg/dl/h; 749 (195), 882 (278) and 1244 (497) respectively, p=0.002. In linear regression analysis only fasting TG levels were a significant predictor of the AUC (Coefficient B = 11.779, p < 0.001). CONCLUSIONS In subjects with longevity syndrome the PPL is similar to controls, which means that high fasting HDL-C has not any beneficial influence on PPL. The fasting TG concentration is the main determinant of PPL. Furthermore, postmenopausal females with hFH have higher TG response postprandially, even in the case of high fasting HDL-C. Whether there is a threshold below or above, where HDL-C becomes a significant independent determinant of PPL is a question to be answered by future research.

Abstract
Epidemiological studies have enhanced the importance of high-density lipoprotein (HDL) as a risk factor for CAD, as well as disability and frailty in the oldest elderly. Therefore, HDL and molecules involved in HDL metabolism seem to be attractive candidates for longevity-promoting factors. A series of observational studies has demonstrated that the predominance of the larger, more lipid-rich HDL2 subclass is a reproducible phenotype among centenarians. This finding was recently evolved by nuclear magnetic resonance technology in quantification of lipoprotein particle size. However, results of investigations into the mechanisms underlying the lipoprotein profiles in the oldest elderly have been conflicting. Genetic variation in cholesteryl ester transfer protein (CETP), which is a carrier protein in reverse cholesterol transport, was demonstrated to have no association with longevity in one study, but to have positive impacts on large HDL particles and longevity in another. Regarding environmental factors, acute phase reactant and nutritional status are frequently associated with HDL-C levels in the oldest elderly, however, the causality of the association remains to be elucidated. Determination of the association between cognitive function and HDL in the oldest elderly is also a future task. To obtain further insight into the mechanistic roles of low HDL in the pathophysiology of geriatric syndrome, a much greater effort should be invested in this research field.

Abstract
Age is associated with an enhanced low density lipoprotein (LDL) oxidation and atherosclerosis, thus, subjects over 80 years without cardiovascular disease provide a model to investigate the protective factors against atherosclerosis. Serum paraoxonase (PON1), an high density lipoprotein (HDL)-bound enzyme, prevents LDL oxidation. The aim of the present study was to evaluate the contribution of the PON1 promoter T(-107)C and coding region Gln192Arg (Q192R) and Leu55Met (L55M) polymorphisms to the resistance to develop cardiovascular events in Sicilian healthy octogenarians. Distribution of PON1 genotypes and activity, and biochemical parameters, were compared between 100 octogenarians and 200 adults. Individuals in the elderly group displayed significant higher levels of HDL-C (P < 0.001) and PON1 activity (P < 0.001). The analysis of PON1 genotypes distribution showed an higher percentage of (-107)CC among octogenarians compared with controls. A significant difference among T(-107)C genotypes respect to PON1 activity and HDL-C levels occurred in both groups. The CC genotype was associated with higher PON1 activity and HDL levels compared to the TT genotypes. In conclusion, our results provide a strong evidence that in healthy Sicilians ageing may be characterized by a low frequency of PON1 (-107)T 'risk' allele and by an high frequency of favourable genotypes such as (-107)CC, influencing PON1 activity and HDL-C levels.

Abstract
The concentration of high density lipoprotein cholesterol (HDL-C) has been found to be a powerful negative predictor of premature coronary heart disease (CHD) and stroke in human prospective population studies. Evidence of the protective properties of HDLs has also been documented in the elderly and their offspring. HDLs mediate several functions that provide an insight into their potential anti-atherogenic mechanisms. Intervention strategies to prevent CHD have generally focused on lowering low-density lipoprotein cholesterol (LDL-C). However, several lifestyle and pharmacological interventions have the capacity to raise the level of HDL-C. As data accumulate on the protective role of HDLs, there is growing support for interventions that act to raise HDL-C concentrations.

Abstract
OBJECTIVES To identify factors associated with remaining healthy in older adults. DESIGN Longitudinal cohort study. SETTING Data were collected at the four Cardiovascular Health Study field centers. PARTICIPANTS 5,888 participants age 65 years and older in the Cardiovascular Health Study. MEASUREMENTS Presence of chronic disease was assessed at baseline and over a maximum 7-year follow-up period. Participants who were free of chronic disease (no cardiovascular disease (CVD), chronic obstructive pulmonary disease, or self-reported cancer, except nonmelanoma skin cancer) at the baseline examination were then monitored for the onset of incident cancer, cardiovascular disease, and fatal outcomes. RESULTS A high proportion of these older adults was healthy at the initial examination and remained healthy over the follow-up period. Numerous behavioral factors were associated with continued health, including physical activity, refraining from cigarette smoking, wine consumption (women), higher educational status, and lower waist circumference. A number of CVD risk factors and subclinical disease measures were associated with continued health, including higher high-density lipoprotein (HDL) cholesterol, lack of diabetes, thinner common carotid intimal nmedial thickness, lower blood pressure, lower C-reactive protein, and higher ankle-arm blood pressure ratio. Among the behavioral factors, exercise, not smoking, and not taking aspirin remained significant predictors of health even after controlling for CVD risk factors and subclinical disease in older adults. CONCLUSIONS These data suggest that a number of modifiable behavioral factors (physical activity, smoking, and obesity) and cardiovascular risk factors (diabetes, HDL cholesterol, and blood pressure) are associated with maintenance of good health in older adults.

Abstract
Low levels of HDL cholesterol have been clearly demonstrated to be associated with an increased incidence of coronary heart disease, strongly suggesting that HDL particles have an antiatherogenic function. However, little information has been available concerning the atherogenicity of a marked hyperalphalipoproteinemia (HALP). There is no agreement about whether plasma cholesteryl ester transfer protein (CETP) deficiency is associated with an antiatherogenic state or not, although this disorder was reported to be one of the major causes of marked HALP. In the current study, we have found a unique area (Omagari City, Akita Prefecture, Japan) where CETP deficiency caused by a G-to-A mutation at the 5' splice donor site of intron 14 in the CETP gene is extremely frequent. In Omagari City, the mutation was detected more than 20 times more frequently and the prevalence of a marked HALP with plasma HDL cholesterol > or = 2.58 mmol/L (100 mg/dL) was 5 to 10 times higher than in other areas of Japan. This discovery has made it possible to perform a large population-based study concerning the atherogenicity of a marked elevation of HDL cholesterol in a genetically more homogeneous population. There was a statistically significant U-shaped relationship between HDL cholesterol levels and the incidence of ischemic changes in electrocardiograms. In cases of HDL cholesterol < 1.81 mmol/L (70 mg/dL), the incidence increased in proportion to the levels of HDL cholesterol. The frequency of the CETP gene mutation was higher in patients with coronary heart disease than in healthy control subjects. In subjects aged > 80 years, the prevalence of both marked HALP and the intron 14 splicing defect was significantly lower than in the younger generation. The current study indicated for the first time that a marked HALP caused by CETP gene mutation may not represent a longevity syndrome, suggesting the importance of reevaluation of the clinical significance and pathophysiology of a marked HALP.

Abstract
We determined the common polymorphism of apolipoprotein E (E2, E3, and E4), apolipoprotein B Xba I polymorphism, and apolipoprotein C-III Sst I polymorphism in almost all Finnish centenarians alive in 1991 (n = 179/185). Plasma lipid and lipoprotein levels in different apolipoprotein genotypes were also measured. In comparison with younger Finnish populations studied previously, the frequency of the apolipoprotein E epsilon 2 allele was almost twice as high (7.0% versus 4.1%; P < .05) and that of the epsilon 4 allele only approximately one third as high (8.4% versus 22.7%; P < .001) in the centenarians. Plasma cholesterol and high-density lipoprotein cholesterol levels tended to be lowest in the group with the epsilon 2 allele (4.33 mmol/L and 1.41 mmol/L, respectively), intermediate in those with the epsilon 3 allele (4.57 mmol/L and 1.48 mmol/L, respectively), and highest in those with the epsilon 4 allele (4.82 mmol/L and 1.60 mmol/L, respectively). The frequencies of the apolipoprotein B X1 and X2 alleles (Xba I restriction site absent or present, respectively) among the centenarians and among the young Finns were not significantly different, whereas the apolipoprotein C-III S2 allele (Sst I restriction site present) occurred more often in the centenarians (frequency, 12.9%) than in the youngest reference population (frequency, 8.8%; P < .05). Centenarians with the apolipoprotein B X2X2 genotype and apolipoprotein E4 phenotype had a higher mean plasma cholesterol level than those with the X1X1 genotype and E2 phenotype (5.24 versus 3.43 mmol/L; P < .05).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
OBJECTIVE To determine factors that characterize those 80 years and over free of clinical coronary heart disease (CHD). DESIGN Cross-sectional intergroup comparison. SETTING Rural New Zealand town. SUBJECTS All those 70 years and over registered with the sole health center. Seven hundred eighty-two subjects were seen, a 91.4% response rate. Subjects were divided by World Health Organization cardiovascular questionnaire criteria, history, examination, and coded 12-lead electrocardiogram into four groups: 1) those 70-79 years of age with evidence of CHD; 2) those 80 years and older with evidence of CHD; 3) those 70-79 years of age free of CHD; and 4) those 80 years and older free of clinical CHD. MEASUREMENTS Mean values and distributions of cholesterol, high-density lipoprotein (HDL) cholesterol, apolipoproteins (apos), triglycerides, insulin, glucose, anthropometric measurements, and psychosocial variables. RESULTS In the initial analysis of variance there was a significant difference in the mean values among the four groups for body mass index (BMI), HDL cholesterol, apo A1, and triglycerides. Using the Duncan procedure, the mean value of HDL cholesterol in the group 80 years and older with no evidence of clinical CHD was significantly higher than in each of the other groups. The group 80 years and older without clinical CHD had a significantly higher mean value for apo A1 and significantly lower mean values for triglycerides and BMI than the group 70-79 years old with CHD (p < 0.05). Three-factor analysis of variance showed those free of clinical CHD had significantly higher values of HDL cholesterol (P = 0.024) and apo A1 (P = 0.022), and lower values of BMI (P = 0.017) and triglycerides (P = 0.018) compared with those who had CHD after controlling for age and sex. Those 80 years and older had lower values of BMI (P = 0.001) and triglycerides (P = 0.018) than those 70-79 years old after controlling for CHD and sex. The group who were 80 years and older and free of clinical CHD had a significantly narrower distribution of values for insulin (P < 0.001), glucose (P = 0.001), diastolic blood pressure (P = 0.001), BMI (P = 0.001), and waist-hip ratio (P = 0.002) when compared with those 80 years and older with CHD; a significantly narrower distribution of values for insulin (P = 0.024), glucose (P = 0.003), and BMI (P = 0.002) when compared with those 79-79 years old with CHD and a significantly narrower distribution of glucose (P = 0.002) and BMI (P = 0.014) when compared with those 70-79 years old and free of clinical CHD. CONCLUSION Those 80 years and older who were free of clinical CHD were characterized by differences in lipid and anthropometric values, particularly higher HDL cholesterol and apo A1 levels. Results were also consistent with this survivor group maintaining tighter homeostatic control over a number of variables.
