    Abstract Siren spp. are often dominant vertebrates in the wetlands they occupy and are known to estivate when such wetlands dry up. Practical considerationslimit in-situ observations of estivating individuals. On 12 October 2021, we incidentally discovered an estivating aggregate of Siren nettingi in Bastrop County, Texas, USA. These salamanders were excavated from compact, rocky soil adjacent to a caliche road, at depths that ranged between ~0.2 to 1.5 m. The dominant vegetation at this site included Ulmus crassifolia, Persicaria sp., and various grass species. We recovered 140 individuals of which seven were salvaged and 133 were captured live. We measured 115 of these for snout–vent length (SVL) and observed the aggregate was predominated by juveniles. We estimated an estivation density of 2.33 sirens/m2 that is comparable to densities estimated for non-estivating populations. However, in-lieu of monitoring that was in place for this study, we expect a mass mortality event would have likely occurred. We therefore suggest that roadway construction in preferred habitat be considered as a threat to siren populations.

    Abstract Background: While a major goal of community-based participatory research (CBPR) is to improve community health; it is unclear how to measure longstanding success of CBPR.
    Objective: We sought to determine the impact of ongoing CBPR on cardiometabolic health of participating communities, including in people not directly participating in research.
    Methods: We used linear mixed-effects modelling with electronic medical records from 2002 to 2012 from the Yukon-Kuskokwim Health Corporation, which provides health care to all Alaska Native people in southwestern Alaska, to compare rates of change in cardiometabolic risk factors between communities that did and did not participate in ongoing CBPR beginning in 2003.
    Results: We analysed 1,262,035 medical records from 12,402 individuals from 10 study and 38 control communities. Blood pressure declined faster in study than in control communities: systolic blood pressure (0.04 mmHg/year; 95% confidence interval [CI]: 0.01, 0.08); diastolic blood pressure (DBP) (0.07 mmHg/year; 95% CI: 0.04, 0.09). Body mass index increased 0.04 units/year faster in study communities than in control communities (95% CI: 0.03, 0.05). More study visits were associated with faster reduction of DBP and triglyceride levels in study communities.
    Conclusions: Ongoing CBPR may improve overall cardiometabolic health in communities, perhaps by increasing engagement in health and advocacy.

    Abstract This review provides an overview of the recent data evaluating triglyceride and low-density lipoprotein (LDL) size, two highly interrelated, genetically influenced, risk factors for cardiovascular disease (CVD). An examination of new epidemiologic studies continues to demonstrate that plasma triglyceride levels predict CVD. The first prospective study of the familial forms of hypertriglyceridemia has shown that relatives in familial-combined hyperlipidemia families are at increased risk for CVD mortality and that triglyceride levels predicted 20-year, CVD mortality among relatives in familial hypertriglyceridemia families. A meta-analysis of three, large-scale, prospective studies in men, and the first study to examine the correlation of LDL particle size distribution and vascular changes measured by B-mode ultrasound, add to growing evidence that small, dense LDL is atherogenic. Quantitative genetic analysis has recently shown substantial pleiotropic (common) genetic effects on triglyceride and LDL size. At least part of this may be explained by variation at the cholesterol ester transfer protein locus on chromosome 16, possibly through its role in reverse cholesterol transport. Taken together, these data provide new insights into the importance of triglyceride and LDL particle size for understanding genetic susceptibility to cardiovascular disease and its prevention.

    Abstract Epidemiologic studies provide increasing evidence that hypertriglyceridemia is a risk factor for cardiovascular disease. A meta-analysis of 17 population-based studies of triglyceride levels and cardiovascular disease identified a 76% increase in cardiovascular disease risk in women and a 31% increase in men associated with a 1 mmol/L increase in triglyceride levels. Additional epidemiologic studies have shown that plasma triglyceride levels and low-density lipoprotein particle size predict subsequent coronary artery disease. Taken together, the existing epidemiologic data may help identify a group of patients who may benefit from interventions aimed at decreasing triglyceride levels associated with an increased risk of cardiovascular disease.

    Abstract Objectives: To determine whether cardiovascular disease can be predicted from plasma triglyceride levels independent of high density lipoprotein (HDL) cholesterol levels.
    Data sources and study selection: Seventeen prospective population-based studies, ranging in publication date from 1965 to 1994, were selected based on uniform criteria. Among the studies, 16 were conducted in men, comprising data for more than 46,000 men, with an average follow-up period of more than eight years. The data from women came from five studies, including nearly 11,000 women with an 11-year average follow-up.
    Data extraction: The meta-analysis protocol comprised the following steps: estimating the relative risk of triglyceride for each individual study; standardizing the relative risks to a 1 mmol/l increase; estimating the variance and weighting relative risks by the inverse of the variance, and estimating the summary relative risk by averaging the weighted relative risks.
    Data synthesis: Among studies of men, relative risks ranged from 1.1 to 2.0, and the summary relative risk was 1.32 (P < 0.05). All five studies of women were statistically significant, with relative risks ranging from 1.7 to 2.0. The summary relative risk was 1.76, higher than that for men, indicating a 76% increase in risk for women. For the studies among men in which HDL cholesterol data were available, multivariate adjusted relative risk was attenuated to 1.14 but was still statistically significant. Although only two studies of women included HDL cholesterol adjustments, the summary relative risk for triglyceride remained statistically significant, with a value of 1.37.
    Conclusions: When all available data are taken into account, increased triglyceride level is a risk factor for cardiovascular disease, independent of HDL cholesterol level. Clinical trials are urgently needed to determine whether lowering plasma triglyceride levels reduces subsequent risk of cardiovascular disease.

    Abstract Based on meta-analysis of prospective studies from the epidemiological literature, TAG is a risk factor for CVD, independent of HDL-cholesterol. The RR values were 1.3 and 1.8 for a 1 mmol/l increase in TAG among men and women respectively. Adjustment for HDL-cholesterol and other risk factors attenuated these estimates, but they remained statistically significant. Recent prospective findings from the Stanford Five City Project (Gardner et al. 1996) and the Physicians' Health Study (Stampfer et al. 1996) further demonstrate that TAG and LDL size are highly inter-related risk factors for CHD. Quantitative genetic analysis from large-scale family studies show that these correlations reflect common genetic influences that may be important for understanding genetic susceptibility to CHD.

    Abstract The clinical relevance of the heterogeneity in the size and density of low-density lipoprotein (LDL) particles is now widely recognized. The evidence from epidemiological studies, family studies and twins studies demonstrates that small, dense LDL (LDL subclass phenotype B) is a common, genetically influenced risk factor for coronary heart disease (CHD). Several atherogenic mechanisms have been proposed to explain the association of small, dense LDL with CHD, including evidence that small, dense LDL is an integral feature of the insulin resistance syndrome. Furthermore, a recent study in elderly Finnish men and women has shown that phenotype B prospectively predicts non-insulin-dependent diabetes mellitus (NIDDM). In addition, ongoing studies of large Japanese-American kindreds will provide valuable data for evaluating small, dense LDL as a marker for genetic susceptibility to both CHD and NIDDM in a high-risk ethnic group.

    Abstract Data from case-control and cross-sectional studies uniformly demonstrate an association between small, dense low-density lipoprotein and risk of coronary heart disease. This relationship may be attributable to the association of small, dense low-density lipoprotein with other atherogenic lipoproteins, the presence of the insulin resistance syndrome in subjects with small low-density lipoprotein, and/or the increased oxidative susceptibility of small, dense low-density lipoprotein particles. Furthermore, because small low-density lipoprotein appears to be a common trait in the general population, more than one of these atherogenic mechanisms may be operating simultaneously to increase risk of coronary heart disease.

    Abstract There is accumulating evidence that subclasses of low-density lipoproteins (LDL) are important in atherosclerosis. Several case-control studies have demonstrated that a predominance of small, dense LDL (LDL subclass phenotype B) is associated with increased risk of coronary heart disease (CHD). Phenotype B is also consistently characterized by an atherogenic lipoprotein phenotype, including increased levels of plasma triglyceride and decreased high-density lipoprotein cholesterol. Family studies and genetic linkage studies demonstrate that LDL subclasses are influenced by a single major gene effect, although this locus (or loci) remain to be definitively mapped. Twin studies confirm the presence of genetic effects, but also show that non-genetic influences are important. Hypolipidemic drugs, beta-blockers, diet and exercise, in particular, appear to influence the expression of LDL subclass phenotypes. This combination of genetic and environmental influences may provide opportunities to develop targeted intervention strategies to reduce CHD risk among genetically susceptible individuals.

    Abstract The Kaiser-Permanente Women Twins Study began with the establishment of a large registry of twins at Kaiser-Permanente, a managed health care program in Oakland, California. In 1978-79, 434 pairs of women twins, 255 monozygotic and 179 dizygotic, with average age 41 years, were recruited from this registry for a study of coronary heart disease risk factors. Previous analyses of these data have shown moderate heritability for blood pressure and high heritability for lipids, even after adjustment for differential environmental covariance between twin types. For GAW8, the data provided included age, race, weight, height, blood pressure, lipids, smoking, alcohol consumption, exercise, degree of contact between co-twins, menstrual status, and medication for hypertension. Exam 2 of this cohort was completed in 1989-90 and has recently reported nearly complete heritability for lipoprotein(a).
