Soil organic carbon is not just for soil scientists: measurement recommendations for diverse practitioners. ECOLOGICAL APPLICATIONS : A PUBLICATION OF THE ECOLOGICAL SOCIETY OF AMERICA 2021; 31:e02290.

Abstract
Soil organic carbon (SOC) regulates terrestrial ecosystem functioning, provides diverse energy sources for soil microorganisms, governs soil structure, and regulates the availability of organically bound nutrients. Investigators in increasingly diverse disciplines recognize how quantifying SOC attributes can provide insight about ecological states and processes. Today, multiple research networks collect and provide SOC data, and robust, new technologies are available for managing, sharing, and analyzing large data sets. We advocate that the scientific community capitalize on these developments to augment SOC data sets via standardized protocols. We describe why such efforts are important and the breadth of disciplines for which it will be helpful, and outline a tiered approach for standardized sampling of SOC and ancillary variables that ranges from simple to more complex. We target scientists ranging from those with little to no background in soil science to those with more soil-related expertise, and offer examples of the ways in which the resulting data can be organized, shared, and discoverable.

Abstract
Background Physical inactivity is an important risk factor for cardiovascular disease (CVD). Atlantic Canada is a region with lower physical activity (PA) levels and poorer CVD outcomes than the rest of Canada. Yet, within-region variation is expected. This study aimed to assess the association between PA and CVD and how this relationship varied on a regional level. Methods This cross-sectional study used data from the Atlantic Partnership for Tomorrow's Health (PATH) Study. The cohort included 823 CVD cases and 2469 age-, sex-, and province of residence-matched controls between the ages 35 and 69. Data collected included self-reported CVD and PA levels as well as information on sociodemographic characteristics, health status, and lifestyle behaviours. Simple and multiple logistic regression were used to assess the association between PA and CVD. Results High PA levels were associated with a 26% reduction in the mean probability of CVD compared with low PA levels across the total population. Compared with high PA levels, moderate and low PA levels were associated with increased odds of CVD across all 4 provinces. However, regional variation was observed, with higher odds of CVD for low-to-moderate PA levels in Newfoundland and Labrador and New Brunswick compared with Nova Scotia and Prince Edward Island. Conclusions Atlantic Canadians experience regional inequalities in the association between PA and CVD. Future work needs to explore underlying pathways driving these regional differences, which may be the impetus for interventions that mitigate risk and CVD burden in populations of greatest need.

Abstract
OBJECTIVES The prevalence of obesity among populations in the Atlantic provinces is the highest in Canada. Some studies suggest that adequate fruit and vegetable consumption may help body weight management. We assessed the associations between fruit and vegetable intake with body adiposity among individuals who participated in the baseline survey of the Atlantic Partnership for Tomorrow's Health (Atlantic PATH) cohort study. METHODS We carried out a cross-sectional analysis among 26 340 individuals (7979 men and 18 361 women) aged 35-69 years who were recruited in the baseline survey of the Atlantic PATH study. Data on fruit and vegetable intake, sociodemographic and behavioural factors, chronic disease, anthropometric measurements and body composition were included in the analysis. RESULTS In the multivariable regression analyses, 1 SD increment of total fruit and vegetable intake was inversely associated with body mass index (-0.12 kg/m2; 95% CI -0.19 to -0.05), waist circumference (-0.40 cm; 95% CI -0.58 to -0.23), percentage fat mass (-0.30%; 95% CI -0.44 to -0.17) and fat mass index (-0.14 kg/m2; 95% CI -0.19 to -0.08). Fruit intake, but not vegetable intake, was consistently inversely associated with anthropometric indices, fat mass, obesity and abdominal obesity. CONCLUSIONS Fruit and vegetable consumption was inversely associated with body adiposity among the participant population in Atlantic Canada. This association was primarily attributable to fruit intake. Longitudinal studies and randomised trials are warranted to confirm these observations and investigate the underlying mechanisms.

Abstract
OBJECTIVE To assess the cost-effectiveness of exenatide 2 mg once-weekly (EQW) compared to dulaglutide 1.5 mg QW, liraglutide 1.2 mg and 1.8 mg once-daily (QD), and lixisenatide 20 μg QD for the treatment of adult patients with type 2 diabetes mellitus (T2DM) not adequately controlled on metformin. METHODS The Cardiff Diabetes Model was applied to evaluate cost-effectiveness, with treatment effects sourced from a network meta-analysis. Quality-adjusted life years (QALYs) were calculated with health-state utilities applied to T2DM-related complications, weight changes, hypoglycemia, and nausea. Costs (GBP £) included drug treatment, T2DM-related complications, severe hypoglycemia, nausea, and treatment discontinuation due to adverse events. A 40-year time horizon was used. RESULTS In all base-case comparisons, EQW was associated with a QALY gain per patient; 0.046 vs dulaglutide 1.5 mg; 0.102 vs liraglutide 1.2 mg; 0.043 vs liraglutide 1.8 mg; and 0.074 vs lixisenatide 20 μg. Cost per patient was lower for EQW than for liraglutide 1.8 mg (-£2,085); therefore, EQW dominated liraglutide 1.8 mg. The cost difference per patient between EQW and dulaglutide 1.5 mg, EQW and liraglutide 1.2 mg, and EQW and lixisenatide 20 μg was £27, £103, and £738, respectively. Cost per QALY gained with EQW vs dulaglutide 1.5 mg, EQW vs liraglutide 1.2 mg, and EQW vs lixisenatide 20 μg was £596, £1,004, and £10,002, respectively. In the probabilistic sensitivity analysis, the probability that EQW is cost-effective ranged from 76-99%. CONCLUSION Results suggest that exenatide 2 mg once-weekly is cost-effective over a lifetime horizon compared to dulaglutide 1.5 mg QW, liraglutide 1.2 mg QD, liraglutide 1.8 mg QD, and lixisenatide 20 μg QD for the treatment of T2DM in adults not adequately controlled on metformin alone.

Abstract
Patients with type 2 diabetes (T2DM) and inadequate glycaemic control on combination metformin (MET) and sulphonylurea (SU) were enrolled in a 24-week, double-blind, randomized, placebo-controlled study with a 28-week extension. The five-dimension EuroQol questionnaire (EQ-5D), SHIELD Weight Questionnaire-9 (WQ-9), Impact of Weight on Quality of Life-Lite (IWQOL-Lite) questionnaire and the Diabetes Treatment Satisfaction Questionnaire (DTSQ) were used to evaluate health status and health-related quality of life (HRQoL) at baseline and week 52. Patients with dapagliflozin 10 mg + MET + SU (n = 108) were compared with patients treated with placebo + MET + SU (n = 108), using a repeated-measures mixed model. EQ-5D visual analogue scale scores, IWQOL-Lite and DTSQ scores improved in the dapagliflozin and placebo groups from baseline to week 52; however, there was no significant difference between groups (p > 0.20). EQ-5D index scores remained the same from baseline to week 52 for dapagliflozin and placebo (p = 0.54). A numerically greater proportion of the dapagliflozin group reported improvement in all nine SHIELD WQ-9 items compared with placebo, and the difference was statistically significant for physical health (p = 0.017). Over 52 weeks of therapy, patients maintained their health status and HRQoL when dapagliflozin was added to the treatment.

Abstract
OBJECTIVE This study ascertained the incidence and resource utilisation of non-fatal myocardial infarction (MI), stroke, coronary bypass surgery or angioplasty among adults with type 2 diabetes mellitus (T2DM) at high risk for cardiovascular disease (CVD) over 3 and 5 years. METHODS Respondents from the US, population-based SHIELD study with T2DM and at cardiovascular risk were stratified into an established CVD cohort and a risk factors cohort. Proportion of respondents self-reporting a new MI, stroke or revascularisation was calculated. Multivariate discrete logistic hazards models were utilised. RESULTS Incidence rate in the established CVD cohort (n = 1198) was 26.3% over 3 years (31.2%, 5 years) and in the risk factors cohort (n = 924) 18.8% over 3 years (26.0%, 5 years). Healthcare resource use was significantly greater among respondents who had a new CV event than among those not experiencing an event (p < 0.001). CONCLUSIONS Individuals with T2DM at risk for CVD had a high incidence of CV events in this large US study, which represents a significant burden on the healthcare system.

Abstract
AIMS This study evaluated change in health-related quality of life (HRQOL) associated with ongoing weight change among patients with type 2 diabetes mellitus (T2DM) treated with dapagliflozin, a highly selective sodium-glucose cotransporter 2 (SGLT2) inhibitor that lowers blood glucose by increasing urinary glucose excretion and is associated with body weight reductions. METHODS Patients with T2DM who had inadequate glycaemic control on metformin (MET) alone were enrolled in a 24-week, double-blind, randomized, placebo-controlled study with a 78-week extension to evaluate the effect of dapagliflozin + MET on body weight. Patients also completed the Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes Weight Questionnaire-9 (SHIELD-WQ-9), a weight change-related HRQOL survey. Difference in proportions of patients treated with dapagliflozin 10 mg + MET (n = 89) or placebo + MET (n = 91) who reported improvement in HRQOL was analysed with Fisher's exact test. RESULTS Dapagliflozin patients had significantly greater weight loss than placebo patients over 102 weeks (p < 0.05). This corresponded to a numerically greater proportion of dapagliflozin-treated patients reporting ongoing weight loss and associated improvements in most HRQOL domains at three different evaluation points (weeks 24, 50 and 102) than placebo-treated patients. In a post-hoc analysis among patients who reported ongoing weight loss regardless of treatment arm, a significantly greater proportion of patients reporting weight loss versus weight gain reported improvements in physical health, self-esteem and overall HRQOL at weeks 24, 50 and 102. CONCLUSIONS Dapagliflozin-induced weight loss was associated with improvement in overall HRQOL. Overall, ongoing weight loss was associated with improvements in several HRQOL domains compared with weight gain.

Abstract
AIMS This study evaluated health status and health-related quality of life (HRQOL) among patients with type 2 diabetes mellitus (T2DM) treated with dapagliflozin, a highly selective sodium-glucose co-transporter 2 (SGLT2) inhibitor that lowers blood glucose by increasing glucose excretion, in a double-blind, randomised clinical trial. METHODS Subjects with T2DM who had inadequate glycaemic control on metformin alone were enrolled in a 24-week, double-blind, randomised, placebo-controlled study with a 78-week extension period to evaluate the effect of dapagliflozin in combination with metformin. Subjects treated with dapagliflozin 10 mg + metformin (n = 89) were compared with subjects treated with placebo + metformin (n = 91) at baseline and at weeks 24, 50 and 102. EQ-5D change from baseline was derived from a repeated-measures mixed model, adjusting for baseline EQ-5D, treatment group, time point and use of rescue medication. RESULTS Mean (SD) EQ-5D index was 0.85 (0.16) and 0.82 (0.15) at baseline and 0.85 (0.19) and 0.84 (0.19) at week 102 for dapagliflozin and placebo, respectively. The model indicated no change over 102 weeks in EQ-5D index scores in either treatment group. Mean (SD) EQ-5D visual analogue scale (VAS) was 72.5 (19.5) and 73.7 (15.6) at baseline and 79.8 (13.3) and 78.2 (12.1) at week 102 for dapagliflozin and placebo, respectively. The model indicated similar small improvements in EQ-5D VAS scores in both groups over 102 weeks. CONCLUSION Patients maintained high HRQOL scores from baseline through week 102 in both treatment groups. Dapagliflozin, a novel SGLT2 inhibitor, did not adversely affect HRQOL over 2 years of treatment.

Abstract
AIMS This study compared health-related quality of life (HRQOL) in adults with type 2 diabetes mellitus (T2DM) who reported their perception of weight change vs. actual weight change. METHODS Respondents to the US Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes (SHIELD) 2008 survey were asked if they had lost, maintained or gained weight compared with 1 year earlier (perception). Respondents also provided their actual weight and completed the SHIELD WQ-9 questionnaire to report how weight change affected 9 aspects of daily life. Perceived weight loss or gain was compared with measured weight change reported (2007 weight - 2008 weight) in those with T2DM. RESULTS In respondents reporting weight loss (n = 762), 75.4% lost weight and 15.9% gained weight. For respondents reporting weight gain (n = 392), 70.2% gained weight and 19.6% lost weight. HRQOL did not differ between those who reported weight loss and actually lost weight vs. those who reported weight loss and actually gained weight (p > 0.05), except for self-esteem (p = 0.004). HRQOL was similar for those who reported weight gain and actually gained weight vs. those who reported weight gain, but actually lost weight (p > 0.20). Respondents who had perceived weight loss had significantly better HRQOL than those who perceived that they had gained weight. CONCLUSIONS Perception of weight loss/gain may be as powerful as actual weight loss/gain in impacting HRQOL among adults with T2DM. Interventions that help individuals lose weight or perceive weight loss in addition to lowering glucose will assist in improving HRQOL.

Abstract
AIMS This investigation determined the proportion of adults newly diagnosed as having type-2 diabetes mellitus (T2DM), and ascertained risk predictors for development of self-reported T2DM. METHODS The US Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes (SHIELD) survey was a 5-year longitudinal study of adults with and without diabetes mellitus. Adults completed a baseline health questionnaire in 2004 and ≥1 annual follow-up survey through 2009. Respondents with no self-reported diagnosis of diabetes at baseline were followed to measure rate of and assess risk factors for development of T2DM over 5 years. RESULTS Among 8582 respondents without diabetes at baseline, 622 (7.2%) reported a diagnosis of T2DM over the subsequent 5 years. Increasing age, family history of T2DM, body mass index ≥30 kg/m(2), abdominal obesity, excessive thirst, asthma, gestational diabetes and 'high blood sugar without diabetes' significantly increased the risk of developing T2DM (p < 0.05 for each). Good to excellent health status and self-reported circulatory problems decreased the risk (p < 0.05 for each). CONCLUSIONS Among this representative US adult population, the rate of developing T2DM was 7.2% over 5 years. Predictors of T2DM diagnosis identified in this analysis were readily obtainable via self-report.

Effect of pressure overload-induced hypertrophy on the expression and localization of p38 MAP kinase isoforms in the mouse heart. Cell Signal 2010; 22:1634-44.

Abstract
p38 mitogen-activated protein kinases (MAPKs) are serine/threonine specific protein kinases that respond to cellular stress and regulate a broad range of cellular activities. There are four major isoforms of p38 MAPK: alpha, beta, gamma, and delta. To date, the prominent isoform in heart has been thought to be p38alpha. We examined the expression of each p38 isoform at both the mRNA and protein level in murine heart. mRNA for all four p38 isoforms was detected. p38gamma and p38delta were expressed at protein levels comparable to p38alpha and 38beta, respectively. In the early phase of pressure-overload hypertrophy (1-7 days after constriction of the transverse aorta), the abundance of p38beta, p38gamma and p38delta mRNA increased; however, no corresponding changes were detected at the protein level. Confocal immunofluorescence studies revealed p38alpha and p38gamma in both the cytoplasm and nucleus. In the established phase of hypertrophy induced by chronic pressure overload (7-28 days after constriction of the transverse aorta), p38gamma immunoreactivity accumulated in the nucleus whereas the distribution of p38alpha remained unaffected. Hence, both p38alpha and p38gamma are prominent p38 isoforms in heart and p38gamma may play a role in mediating the changes in gene expression associated with cardiac remodeling during pressure-overload hypertrophy.

AIMS Guidelines recommend antihypertensive, lipid-lowering and/or antiplatelet therapy for prevention of cardiovascular disease (CVD). This study examined the utilisation of cardiovascular therapies among individuals at CVD risk to assess adherence to guidelines. METHODS Respondents to the SHIELD study were classified based on National Cholesterol Education Program Adult Treatment Panel III risk categories. High coronary heart disease (CHD) risk (n = 7510) was defined as self-reported diagnosis of heart disease/heart attack, narrow or blocked arteries, stroke or diabetes; moderate risk (n = 4823) included respondents with > or = 2 risk factors (i.e., men > 45 years, women > 55 years, hypertension, low high-density lipoprotein cholesterol, smoking and family history of CHD); and low risk (n = 5307) was 0-1 risk factor. Respondents reporting a myocardial infarction, stroke or revascularisation at baseline (prior CVD event) (n = 3777), those reporting a new CVD event during 2 years of follow up (n = 953), and those with type 2 diabetes mellitus (n = 3937) were evaluated. The proportion of respondents reporting treatment with lipid-lowering, antiplatelet or antihypertensive agents was calculated. RESULTS Utilisation of lipid-lowering therapy was low (< or = 25%) in each group. Prescription antithrombotic therapy was minimal among respondents with prior CVD events, but 47% received antihypertensive medication. No use before or after a new CVD event was reported by 36% of respondents for lipid-lowering, 32% for antithrombotic and > 50% for antihypertensive medications. CONCLUSIONS More than 50% of at-risk respondents and > 33% of respondents with new CVD events were not taking CVD therapy as recommended by guidelines.

Characterization of the expression and regulation of MK5 in the murine ventricular myocardium. Cell Signal 2010; 22:1063-75. [PMID: 20214976 DOI: 10.1016/j.cellsig.2010.02.009] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2010] [Revised: 02/02/2010] [Accepted: 02/23/2010] [Indexed: 10/19/2022]
Abstract
MK5, a member of the MAPK-activated protein kinase family, is highly expressed in the heart. Whereas MK2 and MK3 are activated by p38 MAPK, MK5 has also been shown to be activated by ERK3 and ERK4. We studied the regulation of MK5 in mouse heart. mRNA for 5 splice variants (MK5.1-5.5), including the original form (MK5.1), was detected. MK5 comprises 14 exons: exon 12 splicing was modified in MK5.2, MK5.3, and MK5.5. MK5.2 and MK5.5 lacked 6 bases at the 3'-end of exon 12, whereas MK5.3 lacked exon 12, resulting in a frame shift and premature termination of translation at codon 3 of exon 13. MK5.4 and MK5.5 lacked exons 2-6, encoding kinase subdomains I-VI, and were kinase-dead. All 5 MK5 variants were detected at the mRNA level in all mouse tissues examined; however, their relative abundance was tissue-specific. Furthermore, the relative abundance of variant mRNA was altered both during hypertrophy and postnatal cardiac development, suggesting that the generation or the stability of MK5 variant mRNAs is subject to regulation. When expressed in HEK293 cells, MK5.1, MK5.2 and MK5.3 were nuclear whereas MK5.4 and MK5.5 were cytoplasmic. A p38 MAPK activator, anisomycin, induced the redistribution of each variant. In contrast, MK5 co-immunoprecipitated ERK3, but not ERK4 or p38 alpha, in control and hypertrophying hearts. GST pull-down assays revealed unbound ERK4 and p38 alpha but no free MK5 or ERK3 in heart lysates. Hence, 1) in heart MK5 complexes with ERK3 and 2) MK5 splice variants may mediate distinct effects thus increasing the functional diversity of ERK3-MK5 signaling.

Abstract
OBJECTIVE This study evaluated the self-reported method of diagnosis of heart disease (HD) to elucidate whether diagnosis is occurring at early, presymptomatic stages as recommended by the prevention guidelines. METHODS Respondents to the 2006 survey in the US population-based Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes (SHIELD) reported whether a physician told them that they had HD, including heart attack, angina, heart failure, angioplasty or heart bypass surgery. Self-report of age at diagnosis, specialty of physician who made the diagnosis and whether the diagnosis was made after having symptoms, during routine screening or while being treated for another health problem were assessed. Year of diagnosis was categorised into 3-year intervals from 1985 to 2006. Individuals with HD diagnosis with and without type 2 diabetes mellitus (T2DM) were compared using chi-square tests. RESULTS Of 1573 respondents reporting a diagnosis of HD, > 87% were white, > 49% were men and 38% had T2DM. Approximately 19% of respondents reported that their HD diagnosis was made during routine screening. A significantly greater percentage of HD respondents with T2DM reported the diagnosis being made based on symptoms (54%) and while being treated for another health problem (22%) compared with respondents without diabetes (48% symptoms and 15% other health problem, p > 0.05). HD was diagnosed primarily by cardiologists (> 60%) and family doctors (> 25%). CONCLUSION There remains a missed opportunity to diagnose HD at earlier stages through routine screening or during treatment of other health conditions such as diabetes, as many individuals were not diagnosed until they were symptomatic.

Abstract
PURPOSE This study assessed awareness of metabolic syndrome and evaluated health knowledge, attitudes and behaviours of respondents at risk. METHODS Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes (SHIELD), a longitudinal US population-based survey initiated in 2004, included respondents, > or = 18 years of age, reporting a diagnosis of metabolic syndrome. Prevalence of metabolic syndrome was compared in SHIELD and National Health and Nutrition Examination Survey (NHANES) 1999-2002 survey. The proportion of SHIELD respondents who had heard of and/or understood metabolic syndrome was estimated. Respondents at high risk for metabolic syndrome were stratified into attitude-behaviour categories of 'Already Doing It', 'I Know I Should' and 'Don't Bother Me' and differences in attitudes and behaviours were evaluated with chi-square tests. RESULTS Prevalence of reported metabolic syndrome was 0.6% in SHIELD screening questionnaire respondents (n = 211,097) vs. 25.9% in NHANES (n = 10,780). Less than 15% of SHIELD baseline questionnaire respondents (n = 22,001) had heard of or understood metabolic syndrome. Attitudes toward health status were more favourable in the 'Doing' group (27% reported fair/poor health) compared with those in the 'Should' (38%) and 'Don't' (54%) groups (p < 0.0001). The 'Don't' group was most likely to prefer medications to lifestyle change (13% vs. 2-4%) compared with 'Should' and 'Doing' groups (p < 0.0001). More 'Doing' respondents (79%) than 'Should' (59%) and 'Don't' (48%) respondents reported exercising regularly (p < 0.0001). CONCLUSIONS The lack of knowledge about metabolic syndrome reported in SHIELD indicates limited penetration of this concept into public awareness. With behaviour categories, respondents who report healthy attitudes are more likely to embrace lifestyle changes, while respondents who do not care may be more difficult to treat.

Abstract
OBJECTIVES This study compared health-related quality of life (HRQoL) and depression among individuals with type 2 diabetes mellitus (T2D) and those at low or high risk for T2D. METHODS Respondents in a population-based US 2004 survey reported whether they had T2D (n = 3530) or risk factors for T2D [abdominal obesity, body mass index (BMI) >/= 28 kg/m(2), dyslipidaemia, hypertension and history of cardiovascular disease]. Respondents without T2D were stratified into low risk (0-2 risk factors, n = 5335) and high risk (3-5 risk factors, n = 5051). SF-12 version 2 (SF-12) and Patient Health Questionnaire (PHQ)-9 were used to measure HRQoL and depression. Mean scores were compared across the three groups using analysis of variance. Linear regression identified factors associated with SF-12 Physical and Mental Component Summary scores (PCS and MCS), adjusting for age, gender, race, income, geographic region, household size, BMI and group. RESULTS Respondents were mostly women (60%) with mean age of 54 years. Mean PCS scores for T2D and high risk (39.5 and 41.7, respectively) were significantly lower than for low risk (50.6, p < 0.001). After adjustment, high-risk and T2D groups were associated with lower PCS and MCS scores compared with low risk group (p < 0.05). Mean PHQ-9 scores and per cent with moderate-to-severe depression were significantly higher for T2D and high risk than for low risk (p < 0.01). CONCLUSIONS Health-related quality of life and depression scores in T2D were similar to those at high risk, and indicated significant decrements in physical health and greater depression compared with low-risk respondents.

Abstract
OBJECTIVES The study assessed knowledge, attitudes and behaviours towards health, diabetes, diet and exercise among respondents with type 2 diabetes mellitus and those with cardiometabolic risk factors. METHODS Respondents in the SHIELD study reported their health conditions, exercise, diet and weight loss. Three groups were assessed: (i) type 2 diabetes, (ii) high risk (HR) defined as 3-5 of the following factors: abdominal obesity, BMI > or = 28 kg/m(2), reported diagnosis of dyslipidaemia, hypertension, coronary heart disease or stroke and (iii) low risk (LR) defined as < or = 2 factors. Comparisons across groups were made using analysis of variance. RESULTS More type 2 diabetes and HR respondents (> 46%) received recommendations to change their lifestyle habits (increase exercise and change eating habits), compared with < 29% of LR respondents, p < 0.0001. Less than 25% of respondents agreed that type 2 diabetes is not as serious as type 1 diabetes and > 85% agreed that obesity can aggravate or contribute to onset of chronic conditions. Mean number of healthcare visits was highest in type 2 diabetes (11.0) than HR (9.4) and LR (6.1) groups, p < 0.05. Type 2 diabetes and HR respondents were least likely to report exercising regularly (26%), compared with LR (37%), p < 0.05. More type 2 diabetes (70%) and HR (72%) respondents reported trying to lose weight vs. LR respondents (55%), p < 0.05. CONCLUSIONS Type 2 diabetes and HR respondents reported attitudes and knowledge conducive to good health, but the majority of respondents did not translate these positive traits into healthy behaviour with respect to diet, exercise and weight loss.

Abstract
The objectives of this study were to explore the relation between body mass index (BMI) and prevalence of diabetes mellitus, hypertension and dyslipidaemia; examine BMI distributions among patients with these conditions; and compare results from two national surveys. The Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes (SHIELD) 2004 screening questionnaire (mailed survey) and the National Health and Nutrition Examination Surveys (NHANES) 1999-2002 (interview, clinical and laboratory data) were conducted in nationally representative samples>or=18 years old. Responses were received from 127,420 of 200,000 households (64%, representing 211,097 adults) for SHIELD, and 4257 participants for NHANES. Prevalence of diabetes mellitus, hypertension and dyslipidaemia was estimated within BMI categories, as was distribution of BMI levels among individuals with these diseases. Mean BMI was 27.8 kg/m2 for SHIELD and 27.9 kg/m2 for NHANES. Increased BMI was associated with increased prevalence of diabetes mellitus, hypertension and dyslipidaemia in both studies (p<0.001). For each condition, approximately [corrected] 75% or more [corrected] of patients had BMI>or=25 kg/m2. Estimated prevalence of diabetes mellitus and hypertension was similar in both studies, while dyslipidaemia was substantially higher in NHANES than SHIELD. In both studies, prevalence of diabetes mellitus, hypertension and dyslipidaemia occurred across all ranges of BMI, but increased with higher BMI. However, not all overweight or obese patients had these metabolic diseases and not all with these conditions were overweight or obese. Except for dyslipidaemia prevalence, SHIELD was comparable with NHANES. Consumer panel surveys may be an alternative method to collect data on the relationship of BMI and metabolic diseases.

Abstract
The primary objective of this study was to compare the antihypertensive efficacy and safety of intravenously administered nicardipine with that of intravenous nitroprusside (SNP) in patients with severe hypertension. The study was conducted in 121 patients with severe hypertension (diastolic blood pressure [BP] > 120 mm Hg, or systolic BP > 200 mm Hg). Patients were randomized to receive intravenous nicardipine or SNP. Drugs were administered according to a predetermined dosing schedule for a 10 to 12 h period. Sixty-one patients were randomized to intravenous nicardipine and 60 to SNP. Pretreatment BP values for the nicardipine and SNP groups were 217/128 mm Hg and 219/128 mm Hg, respectively. Therapeutic response (diastolic BP < 100 mm Hg, or a decrease of > 15 mm Hg; systolic BP < 180 mm Hg, or a decrease of > 20 mm Hg) was achieved in 98% (60/61) of patients treated with nicardipine and 93% (56/60) of patients treated with SNP. The mean decreases in systolic and diastolic BP were 61 mm Hg and 40 mm Hg after 4 h of nicardipine, and 59 mm Hg and 38 mm Hg after 4 h of SNP. The mean increases in heart rate also were similar in both groups (nicardipine, 12 beats/min; SNP 10 beats/min). The mean numbers of dose adjustments per hour required to maintain the BP reductions were lower (P < .01) in the nicardipine-treated patients (0.5 +/- 0.1 times per hour) than in the SNP-treated patients (1.5 +/- 0.2 times per hour).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Nicardipine hydrochloride was administered intravenously to two groups of hypertensive patients: one group of 37 patients with mild to moderate hypertension and one group of 20 patients with severe hypertension. In the first group, doses of 0.5, 1, 2, and 4 mg/hr, as well as placebo, were infused for 48 hours in a double-blind fashion. Blood pressure and heart rate were monitored for this period and for the 24 hours after the infusion was discontinued. Significant decrements in blood pressure were noted with all doses; 4 mg/hr produced lowering that was greater than all other doses; 1 and 2 mg/hr produced lowering that was greater than 0.5 mg/hr but that were not different from each other. Excellent correlation of blood pressure reduction and plasma level was observed and linear kinetics existed. In the severe hypertensive patients, 1, 2, 4, 5, and 8 mg/hr were infused to established minimal and ineffective doses. One milligram per hour was an ineffective dose; 4, 5, and 8 mg/hr all produced significant reductions over the course of the study that were undistinguishable from each other. Two milligrams per hour produced modest reductions in blood pressure. Blood pressure reduction also correlated with plasma levels in the severe hypertensive group.

Abstract
In a double-blind, randomized placebo controlled study, the effect of intracoronary (IC) nicardipine (0.4 mg) on methylergonovine (0.4 mg) induced coronary artery spasm was assessed in 16 patients with a history of variant angina. Reversal of the methylergonovine-induced coronary artery spasm was observed in 100% of patients treated with IC nicardipine and 25% of patients treated with placebo (p less than 0.01). There were no significant differences between the nicardipine and placebo treatment groups with respect to heart rate, blood pressure, proportion of patients experiencing chest pain or ST segment changes. These findings demonstrate that IC nicardipine is safe and could be effective in the reversal of coronary artery spasm in patients with variant angina.
