Abstract
This study aimed to investigate the impact of the cumulative burden of metabolic syndrome (MetS) on the incidence of retinal vein occlusion (RVO) in young adults. We included 1,408,093 subjects aged ≥20 and <40 years without a history of RVO who underwent four consecutive annual health examinations during 2009-2012 from the database of the Korean National Health Insurance Service. The metabolic burden was evaluated based on the cumulative number of MetS diagnoses at each health examination (0-4 times) and the cumulative number of each MetS component diagnosed at each health examination (0-4 times per MetS component). Cox proportional hazards models were used to estimate the risk of RVO according to metabolic burden. The risk of RVO was positively correlated with the cumulative number of MetS diagnoses over the four health examinations. All five MetS components were independently associated with an increased risk of RVO. Subgroup analysis for the impact of MetS on RVO occurrence revealed that MetS had a greater impact on female subjects (P <0.001). Prompt detection of metabolic derangements and their treatment might be important to decrease the risk of RVO in young adults, especially women.

Visceral adipose tissue adiponectin predicts excess weight loss after bariatric surgery in females with severe obesity. Int J Obes (Lond) 2024; 48:247-253. [PMID: 37923928 DOI: 10.1038/s41366-023-01406-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 10/14/2023] [Accepted: 10/20/2023] [Indexed: 11/06/2023]
Abstract
OBJECTIVE Bariatric surgery not always results in satisfactory excess weight loss (EWL) in severe obesity. Given the economic and clinical costs of bariatric surgery failure, defining predictors of successful EWL represents a relevant clinical issue for the health system to select patients benefiting from operation. METHODS By ELISA and Western blot analyses, we assessed the predicting value of pre-operative adiponectin (APN) locally produced in abdominal visceral (VAT) and subcutaneous (SAT) adipose tissue versus plasma levels as a novel sex-linked biomarker of EWL at different time points of follow up (6-24 months) after bariatric surgery in 43 patients (56% females) affected by severe obesity undergoing a small pilot observational study. RESULTS VAT-APN was lower in females and represented the only marker significantly correlated with EWL. In females, VAT-APN in the distribution upper quartile but not baseline BMI retained a statistically significant correlation with EWL at any time points (6-24 months) at multivariate analysis. The best VAT-APN cut-off value to predict 95% EWL at 12 months from surgery (98% accuracy, 100% sensitivity, 94% specificity, p = 0.010) was 5.1 µg/mg. CONCLUSIONS In this very preliminary study, APN in VAT rather than its circulating or subcutaneous levels predicts EWL after bariatric surgery as an independent factor in the female sex only, thus contributing to identify those patients who could much benefit from surgery.

Abstract
BACKGROUND Although gestational diabetes mellitus and delivering high-birthweight infants are known to predict a higher risk of future type 2 diabetes mellitus, the association of hypertensive disorders of pregnancy and other adverse pregnancy outcomes with type 2 diabetes mellitus is not well established. OBJECTIVE This study aimed to examine the associations between different types of adverse pregnancy outcomes and incident type 2 diabetes mellitus among postmenopausal women. STUDY DESIGN The Women's Health Initiative, a nationwide cohort of postmenopausal women, collected self-reported history of adverse pregnancy outcomes, including gestational diabetes mellitus, hypertensive disorders of pregnancy, preterm birth, and delivering low- birthweight (<2500 g) or high-birthweight (>4500 g) infants. Participants were followed up annually for self-reported incident type 2 diabetes mellitus treated with medication from baseline (1993-1998) to March 2021. This study used logistic regression to examine the associations of any and individual adverse pregnancy outcomes with diabetes mellitus. Stratified analyses were performed to assess effect modification by body mass index, race and ethnicity, education, parity, breastfeeding, and age at first birth. RESULTS This analysis included 49,717 women without a history of diabetes mellitus at enrollment who had a least 1 pregnancy and responded to the questionnaire about adverse pregnancy outcomes. After adjusting for body mass index, demographic, lifestyle, and reproductive factors, gestational diabetes mellitus (odds ratio, 2.26; 95% confidence interval, 1.94-2.63), high birthweight (odds ratio, 1.30; 95% confidence interval, 1.18-1.44), and hypertensive disorders of pregnancy (odds ratio, 1.18; 95% confidence interval, 1.08-1.30) were independently associated with higher odds of type 2 diabetes mellitus, whereas preterm birth and low birthweight were not associated with diabetes mellitus risk. A history of ≥2 adverse pregnancy outcomes was associated with higher odds of type 2 diabetes mellitus (odds ratio, 1.55; 95% confidence interval, 1.28-1.88). This study further observed higher odds of type 2 diabetes mellitus (odds ratio, 3.69; 95% confidence interval, 2.38-5.70) among women with a history of both gestational diabetes mellitus and hypertensive disorders of pregnancy than those without any adverse pregnancy outcomes. CONCLUSION Postmenopausal women with a history of gestational diabetes mellitus, those delivering high-birthweight infants, or those with hypertensive disorders of pregnancy are at risk of future type 2 diabetes mellitus. In addition, women with ≥2 conditions had an augmented risk and might be prioritized for screening and prevention efforts for type 2 diabetes mellitus.

Abstract
Free fatty acid (FFA) deposition in non-adipose tissues such as the heart is a characteristic of insulin resistant states which feature hyperinsulinemia and dipeptidyl peptidase-4 (DPP-4) activation. Estrogen-progestin oral contraceptives (OC) treatment reportedly increased DPP-4 activity in rat tissue, and DPP-4 inhibitors have anti-diabetic and anti-inflammatory properties. This study aims to investigate the effects of DPP-4 inhibition on cardiac FFA deposition in estrogen-progestin-treated female rats. From our data, estrogen-progestin OC exposure in female rats led to elevated plasma insulin, cardiac DPP-4 activity, FFA and triglyceride (TG) accumulation, TG/high-density lipoprotein cholesterol (TG/HDL-C) ratio, adenosine deaminase/xanthine oxidase/uric acid pathway (ADA/XO/UA), lipid peroxidation, glycogen synthase activity, and alanine phosphatase; whereas cardiac glucose-6-phosphate dehydrogenase, Na+/K+-ATPase and nitric oxide (NO) were decreased. However, DPP-4 inhibition resulted in decreased plasma insulin, cardiac DPP-4 activity, FFA, TG, TG/HDL-C ratio, and alkaline phosphatase. These were accompanied by reduced ADA/XO/UA pathway, lipid peroxidation, and augmented NO and Na+/K+-ATPase in estrogen-progestin OC-treated rats. DPP-4 inhibition attenuated cardiac lipid deposition accompanied by reduced activity in the ADA/XO/UA pathway in estrogen-progestin OC-treated female rats. DPP-4 is therefore a plausible therapeutic target in cardiometabolic disorders.

Factors Associated with Reduction in Physical Activity during the COVID-19 Pandemic in São Paulo, Brazil: An Internet-Based Survey Conducted in June 2020. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:11397.

Abstract
BACKGROUND The COVID-19 pandemic negatively affected physical activity levels. This study investigated the factors associated with the change in physical activity level in Brazilians residing in the city of São Paulo. METHODS A self-administered questionnaire, addressing personal data, restriction level, education level, family income, daily working hours, and physical activity level, was answered by 2140 volunteers, of which 1179 were excluded because the answers were either incomplete or the respondents were not from São Paulo. The total number of participants selected was 961 (581 female and 380 male). RESULTS The physical activity level adopted prior to the pandemic period (p < 0.001) and family income (p = 0.001) correlated significantly with physical activity level reduction during the pandemic. The proportion of people who reduced their physical activity was greater among those who were very active than those who were active (adjusted prevalence ratio [aPR]: 0.65 [confidence interval (CI): 0.52-0.80]) or insufficiently active [aPR: 0.39 (0.18-0.82)]. The proportion of people who reduced their physical activity was greater among those who received a salary less than minimum wage (MW) than those who received a salary between three to six times minimum wage [(aPR: 0.50 (CI 0.35-0.70)] or more than 6 MW [(aPR: 0.56 (CI 0.40-0.79)]. CONCLUSIONS A higher prevalence of Brazilians residing in the city of São Paulo reduced their physical activity who had a vigorous level of physical activity prior to the pandemic and who received less than a MW.

Abstract
BACKGROUND In 2018, a Department of Veterans Affairs (VA) primary care service and a school of pharmacy collaborated to offer introductory pharmacy practice experiences (IPPEs) in population health. Working remotely from the VA facility, students spent 2 hours per week using information from VA clinical dashboards and electronic health records (EHRs) to perform population health activities. Beginning August 2020, women's health initiatives were incorporated. OBJECTIVE The objective was to evaluate student learning and productivity in an established remote population health IPPE that included women's health initiatives during a coronavirus disease (COVID-19)-related university closure. PRACTICE DESCRIPTION During 2 IPPE semesters, activities of second-year student pharmacists were tracked. The course is typically conducted remotely at the university; however, owing to COVID-19 restrictions, students completed the course from their homes. Students were granted remote access privileges to VA's EHR and precepted by VA clinical pharmacists using Microsoft Teams. Students performed prescription drug monitoring program activities; reviewed outside medical records for breast and cervical cancer screening results, laboratory test results for diabetes, and medication safety monitoring; and documented progress notes. PRACTICE INNOVATION Population health IPPEs can be tailored each semester to include a variety of initiatives. Activities are conducted remotely, eliminating the need for space and computers at the VA facility. The remote design enabled students to continue the IPPE during COVID-19 restrictions. EVALUATION Students completed a survey about their confidence performing population health activities at baseline and at the completion of the IPPE. Student workload data were collected over 2 semesters. RESULTS A total of 70 students reviewed 8865 health records and documented 5322 progress notes. Statistically significant improvements in student's reported abilities were reported from baseline to course completion such as explaining breast and cervical cancer screening recommendations. CONCLUSION Incorporating women's health initiatives into a remote population health IPPE assisted the VA facility with population health activities and increased students' perceived skill.

Abstract
OBJECTIVE To evaluate the association between different pre-eclampsia (PE) phenotypes and the development of metabolic syndrome postpartum, in order to identify the subgroup of formerly pre-eclamptic women with a worse cardiovascular risk profile requiring tailored postpartum follow-up. METHODS This was a cohort study of 1102 formerly pre-eclamptic women in whom cardiovascular and cardiometabolic evaluation was performed at least 3 months postpartum. Women were divided into four subgroups based on PE resulting in delivery before 34 weeks (early-onset (EO)) or at or after 34 weeks (late onset (LO)) of gestation and whether they delivered a small-for-gestational-age (SGA) neonate. Metabolic syndrome was diagnosed as the presence of hyperinsulinemia along with two or more of: body mass index ≥ 30 kg/m2 ; dyslipidemia; hypertension; and microalbuminuria or proteinuria. Data were compared between groups using ANOVA after Bonferroni correction. Odds ratios (OR) were calculated using logistic regression to determine the association between metabolic syndrome and the four subgroups. We constructed receiver-operating characteristics curves and computed the area under the curve (AUC) to quantify the ability of different obstetric variables to distinguish between women who developed metabolic syndrome and those who did not. RESULTS The prevalence of metabolic syndrome was higher in women with EO-PE and SGA (25.8%) than in those with EO-PE without SGA (14.7%) (OR 2.01 (95% CI, 1.34-3.03)) and approximately five-fold higher than in women with LO-PE with SGA (5.6%) (OR 5.85 (95% CI, 2.60-13.10)). In women with LO-PE, the prevalence of metabolic syndrome did not differ significantly between women with and those without SGA. Multivariate analysis revealed that a history of SGA, a history of EO-PE and systolic blood pressure at the time of screening are the best predictors of developing metabolic syndrome postpartum. The AUC of the model combining these three variables was 74.6% (95% CI, 70.7-78.5%). The probability of the presence of metabolic syndrome was calculated as: P = 1/(1 + e-LP ), where LP is linear predictor = -8.693 + (0.312 × SGA (yes = 1)) + (0.507 × EO-PE (yes = 1)) + (0.053 × systolic blood pressure). CONCLUSIONS The incidence of metabolic syndrome postpartum was associated more strongly with EO-PE in combination with SGA as compared with LO-PE or EO-PE without SGA. Both time of onset of PE and fetal growth affect the risk of metabolic syndrome after a pre-eclamptic pregnancy. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
PURPOSE OF REVIEW This article discusses the state of type 2 diabetes (T2D) self-management research on non-Hispanic Black men with a focus on their knowledge of diabetes, factors that impact T2D self-management and intervention research that specifically targets non-Hispanic Black men with T2D. RECENT FINDINGS Studies on T2D knowledge and barriers and facilitators to T2D self-management in non-Hispanic Black men are limited to small qualitative focus group and in-depth interviews. To date, few T2D interventions for non-Hispanic Black men have been developed and tested. Research shows that non-Hispanic Black men's knowledge of T2D may be less than optimal compared to non-Hispanic white men. Factors that influence T2D self-management in non-Hispanic Black men include gender-related values and beliefs, and a range of other psychosocial (e.g., social support) and structural (e.g., access to health care) factors. Interventions with gender-specific programming may show promise. More studies with larger sample sizes and longitudinal designs are needed to develop programming to effectively target this at-risk population.

Abstract
AIM We sought to examine whether parity is associated with higher incidence of metabolic syndrome in postmenopausal women. METHODS We conducted a cross-sectional study on 4098 Korean postmenopausal women by using nationally representative data from the Korea National Health and Nutrition Examination Survey 2010-2012. Multivariate logistic regression was performed to evaluate the relationship between parity and metabolic syndrome, with adjustment for potential confounding variables. RESULTS The rate of metabolic syndrome was significantly higher with increasing number of parity, with dose-response relationship in univariate analysis (P <0.001). In addition, higher parity (≥3 live births) was associated with more prevalence of all components of metabolic syndrome compared with two live births (parity 2 vs 3 vs ≥4: 5.5 vs 12.1 and 14.4%, respectively; P < 0.001). However, after adjusting for demographic, socioeconomic, lifestyle and reproductive factors, we found that only higher parity was significantly associated with metabolic syndrome compared with two live births, and failed to show a dose-dependent relationship (parity 2 vs 3 vs ≥4: odds ratio 1 vs 1.404 vs 1.379, respectively; P = 0.043). We also proved that among the components of metabolic syndrome, only waist circumference had a significant positive relationship with parity in a multivariable adjusted model (parity 2 vs 3 vs ≥4: odds ratio 1 vs 1.559 vs 1.656, respectively; P < 0.001). CONCLUSION Higher parity was independently associated with a higher risk of metabolic syndrome in postmenopausal women.

Effect of adiposity on tissue-specific adiponectin secretion. PLoS One 2018; 13:e0198889. [PMID: 29924824 PMCID: PMC6010237 DOI: 10.1371/journal.pone.0198889] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Accepted: 05/28/2018] [Indexed: 02/08/2023] Open
Abstract
Circulating adiponectin levels are lower in individuals with increased BMI and central adiposity. However, they are paradoxically higher in those with peripheral adiposity. We hypothesized that adiponectin secretion from central and peripheral adipose tissue depots may be associated with adiposity levels and its distribution. A total of 55 subjects (69% women) undergoing elective abdominal surgery (mean age: 53 ± 13 years) were recruited. Health history, anthropometrics, and cardiovascular disease risk factor measurements were obtained. Subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) samples were obtained and cultured. Media was collected after 24hr and adiponectin released into the medium was measured using ELISA. We found that mean adiponectin levels from SAT and VAT in all subjects were 17.14±15.27 vs. 15.21±14.28 pg/ml/mg of tissue respectively (p = ns). However, adiponectin secretion from VAT correlated negatively with BMI (r = -0.31, p = 0.01), whereas there was no relationship with SAT (r = 0.08 p = 0.61). Similarly, waist circumference and estimated VAT percentage were both negatively correlated with VAT secretion of adiponectin (r = -0.35, p = 0.01 and r = -0.36, p = 0.02 respectively). These negative correlations were significant only in women on gender-stratified analyses. Adiponectin secretion from VAT decreases with increases in adiposity, while SAT secretion remains unchanged, especially in women. This observation may explain lower circulating adiponectin levels in individuals with central obesity. Further studies are needed to explore the mechanism behind this discrepant adiponectin secretion from SAT and VAT with increases in BMI, particularly among women.

Diabetes and the hospitalized patient : A cluster analytic framework for characterizing the role of sex, race and comorbidity from 2006 to 2011. Health Care Manag Sci 2017; 21:534-553.

Abstract
In the US, one in four adults has two or more chronic conditions; this population accounts for two thirds of healthcare spending. Comorbidity, the presence of multiple simultaneous health conditions in an individual, is increasing in prevalence and has been shown to impact patient outcomes negatively. Comorbidities associated with diabetes are correlated with increased incidence of preventable hospitalizations, longer lengths of stay (LOS), and higher costs. This study focuses on sex and race disparities in outcomes for hospitalized adult patients with and without diabetes. The objective is to characterize the impact of comorbidity burden, measured as the Charlson Weighted Index of Comorbidities (WIC), on outcomes including LOS, total charges, and disposition (specifically, probability of routine discharge home). Data from the National Inpatient Sample (2006-2011) were used to build a cluster-analytic framework which integrates cluster analysis with multivariate and logistic regression methods, for several goals: (i) to evaluate impact of these covariates on outcomes; (ii) to identify the most important comorbidities in the hospitalized population; and (iii) to create a simplified WIC score. Results showed that, although hospitalized women had better outcomes than men, the impact of diabetes was worse for women. Also, non-White patients had longer lengths of stay and higher total charges. Furthermore, the simplified WIC performed equivalently in the generalized linear models predicting standardized total charges and LOS, suggesting that this new score can sufficiently capture the important variability in the data. Our findings underscore the need to evaluate the differential impact of diabetes on physiology and treatment in women and in minorities.

Abstract
BACKGROUND Physiological adaptations occurring across successive pregnancies may increase the risk of adverse cardiovascular health outcomes in later life. METHODS AND RESULTS The association between parity and metabolic syndrome was examined among 7467 Hispanic/Latina women of diverse backgrounds, aged 18 to 74 years, who participated in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) from 2008 to 2011. Metabolic syndrome components were defined according to American Heart Association/National Heart, Lung, and Blood Institute criteria and included abdominal obesity, elevated triglycerides, low high-density lipoprotein cholesterol, high blood pressure, and elevated fasting glucose. Logistic regression models estimated odds ratios (ORs) adjusting for sociodemographic, behavioral, and reproductive characteristics. At HCHS/SOL baseline, women reported none (21.1%), 1 (19.9%), 2 (25.7%), 3 (18.6%), 4 (8.8%), and ≥ 5 (5.9%) live births. When compared with women with 1 birth, those with 4 births had the highest odds of abdominal obesity (OR, 2.0; 95% confidence interval, 1.5-2.8) and overall metabolic syndrome (OR, 1.4; 95% confidence interval, 1.0-2.0) and those with ≥ 5 births had the highest odds of low high-density lipoprotein cholesterol (OR, 1.5; 95% confidence interval, 1.2-2.0) and elevated fasting glucose (OR, 1.6; 95% confidence interval, 1.1-2.4), after adjusting for age, background, education, marital status, income, nativity, smoking, physical activity, menopause, oral contraceptive use, hormone therapy, and field center. Further adjustment for percent body fat attenuated these associations. No associations were observed between parity and elevated triglycerides or high blood pressure. CONCLUSIONS Higher parity is associated with an increased prevalence of selected components of the metabolic syndrome among Hispanic/Latina women in the US. High parity among Hispanics/Latinas with a high prevalence of abdominal obesity suggests high risk for metabolic dysregulation.

Abstract
AIM The study was aimed to evaluate the influence of gender on left ventricular (LV) remodeling in metabolic syndrome (MetS). METHODS AND RESULTS We enrolled 200 subjects without diabetes or overt cardiovascular diseases, never treated with anti-hypertensive drugs or statins: 60 men and 40 women with MetS matched by age, gender and 24 h systolic and diastolic blood pressure (BP) with 60 men and 40 women without MetS. The patients underwent blood tests, 24 h our BP monitoring, LV echocardiographic examination. LV mass indexed by eight(2.7) was significantly greater in men and women with MetS than without MetS. Compared with women without MetS, women with MetS had significantly higher posterior wall thickness and relative wall thickness, greater prevalence of LV concentric remodeling/hypertrophy and lower indices of LV diastolic function, whereas all these parameters were not significantly different between men with and without MetS. MetS was an independent predictor of relative wall thickness and LV mass index in women, but not in men. CONCLUSION The impact of MetS on LV remodeling is significantly influenced by gender: the effects of MetS are more pronounced in women, with development of LV concentric hypertrophy/remodeling and preclinical diastolic dysfunction.

Abstract
Background Known associations between diabetes and cancer could logically be attributed to hyperglycemia, hypersecretion of insulin, and/or insulin resistance. This study examined the relationship between initial glycemic biomarkers among men and women with impaired fasting glucose or undiagnosed diabetes and cancer mortality during follow up. Methods The cohort included subjects aged 40 years and above from the Third National Health and Nutrition Examination Survey (NHANES III) with fasted serum glucose >100 mg/dl without the aid of pharmaceutical intervention (insulin or oral hypoglycemics). Cancer mortality was obtained from the NHANES III-linked follow-up database (up to December 31, 2006). A Cox regression model was applied to test for the associations between cancer mortality and fasting serum glucose, insulin, glycosylated hemoglobin (HbA1c), C-peptide, insulin like growth factor (IGF-1), IGF binding protein 3 (IGFBP3) and estimated insulin resistance. Results A total of 158 and 100 cancer deaths were recorded respectively from 1,348 men and 1,161 women during the mean 134-month follow-up. After adjusting for the effect of age and smoking in women, all-cause cancer deaths (HR: 1.96 per pmol/ml, 95% CI: 1.02–3.77) and lung cancer deaths (HR: 2.65 per pmol/ml, 95% CI: 1.31–5.36) were specifically associated with serum C-peptide concentrations. Similar associations in men were not statistically significant. Serum glucose, HbA1c, IGF-1, IGFBP3 and HOMA were not independently related to long-term cancer mortality. Conclusion C-peptide analyses suggest a modest association with both all-cause and lung cancer mortality in women but not in men. Further studies will be required to explore the mechanisms.

Abstract
Obesity, metabolic syndrome, and diabetes are becoming a leading health concern in the developed Countries, due to their link to cardiovascular disease. These conditions are common in women in the post-menopausal period. Unfortunately, actual lifestyle change strategy fail to prevent cardiovascular events for several reasons, thus specific medications are needed. In addition, it was showed an increased cardiovascular diseases and breast cancer risk in postmenopausal women taking estrogens alone or with progestin, thus the optimal therapy for the prevention of chronic disease in women is still lacking. Androgens exert different actions on organs like adipose tissue, brain, bone, and on cardiovascular system. However, a debate still exists on the positive role of androgens on human health, especially in women. Furthermore, the vascular effects of androgens remain poorly understood and have been controversial for a long time. Sex hormones are important determinants of body composition. Aging is, often, accompanied by a decrease in free testosterone levels, a concomitant reduction in muscle mass and an increase in fat mass. Furthermore, numerous studies showed that total serum testosterone levels were inversely related to the atherosclerosis disease incidence in postmenopausal women. New therapeutic targets may, therefore, arise understanding how androgen could influence the fat distribution, the metabolic disease onset, the vascular reactivity and cardiovascular risk, in both sex.

Abstract
The aim of this study was to investigate the influencing factors that characterize low density lipoprotein (LDL) phenotype and the levels of LDL particle size in healthy Korean women. In 57 healthy Korean women (mean age, 57.4 ± 13.1 yrs), anthropometric and biochemical parameters such as lipid profiles and LDL particle size were measured. Dietary intake was estimated by a developed semi-quantitative food frequency questionnaire. The study subjects were divided into two groups: LDL phenotype A (mean size: 269.7Å, n = 44) and LDL phenotype B (mean size: 248.2Å, n = 13). Basic characteristics were not significantly different between the two groups. The phenotype B group had a higher body mass index, higher serum levels of triglyceride, total-cholesterol, LDL-cholesterol, apolipoprotein (apo)B, and apoCIII but lower levels of high density lipoprotein (HDL)-cholesterol and LDL particle size than those of the phenotype A group. LDL particle size was negatively correlated with serum levels of triglyceride (r = -0.732, P < 0.001), total-cholesterol, apoB, and apoCIII, as well as carbohydrate intake (%En) and positively correlated with serum levels of HDL-cholesterol and ApoA1 and fat intake (%En). A stepwise multiple linear regression analysis revealed that carbohydrate intake (%En) and serum triglyceride levels were the primary factors influencing LDL particle size (P < 0.001, R2 = 0.577). This result confirmed that LDL particle size was closely correlated with circulating triglycerides and demonstrated that particle size is significantly associated with dietary carbohydrate in Korean women.

Abstract
OBJECTIVE To determine whether there are any age-related disparities in the frequency of provision of counseling and education for diabetes care in a large HMO in Central Texas. METHODS EMR search from 13 primary care clinics on patients aged ≥18 years (n=1300) who had been diagnosed with type 2 diabetes. RESULTS There were no significant age differences in the frequency of provision of counseling about HBGM, diet, smoking or diabetes education. However, there were significant age differences in the provision of exercise counseling. Patients aged ≥75 were significantly less likely to have been provided exercise counseling than those aged <65 (adjusted OR=0.60; 95% CI=0.37-0.98). The mean HbA1c for patients aged ≥75 and 65-74 were significantly lower than that of patients aged <65 (8.9 vs. 9.0 vs. 9.7; P<0.001). CONCLUSION While age-related variations in self-management protocols were not found, the provision of formal diabetes education was low (29.4%). The persistence of key risk factors in later life (e.g., obesity) underscores the need for better self-management protocols for older adults. PRACTICE IMPLICATIONS Additional efforts on strategies to increase counseling about lifestyle habits and diabetes self-management care by appropriate health care providers is needed. Diabetes counseling should be individually tailored in older population.

Abstract
The phrase 'women's health research' embraces women as part of the biomedical research engine while categorizing women as separate. Before personalized medicine can become a reality, we must first ensure that basic physiological differences between the sexes are clearly delineated. In this article we argue that research into sex differences should be encouraged at the most fundamental levels of the biomedical sciences. Moreover, appropriate representation of both sexes as participants in clinical studies is still critically needed. Academic and governmental organizations must continue to articulate strong policy in order to ensure inclusion and analysis of sex as a critical variable. Focused attention on sex as a contributing factor to health, disease and therapeutic activity will increase our fund of knowledge regarding our everyday health, increase the pace of clinical research and ensure a healthier population.

Abstract
BACKGROUND Guidelines recommend that LDL-C level should be <100mg/dl among diabetes mellitus (DM) and coronary heart disease (CHD) patients. OBJECTIVE To evaluate how patients with DM and CHD differ in attaining the target level and to examine the association between goal achievement, demographic and clinical parameters. METHODS The study was conducted in Maccabi Healthcare Services, the second largest health maintenance organization in Israel. All patients with DM (n=54,261), CHD (n=24,083) or DM and CHD (n=15,370) who were listed in the computerized database and had at least one LDL-C level measurement between January 1, 2007 and July 15, 2008 were eligible. The percentage of patients who attained LDL-C level <100mg/dl and its association with demographic and clinical parameters were analyzed. RESULTS The rate of reaching the LDL-C target level was higher among the CHD and CHD and DM patients than DM ones (67% vs. 57% vs. 50%, p<0.001, respectively). Male gender; 5th socioeconomic status quintile; underlying disease i.e. CHD, CHD and DM; high statins compliance; and revascularization by percutaneous coronary intervention predicted for reaching target level. DM; absence of renal function evaluation; hospitalizations; HbA1C>7% or missing its measurements had a negative predictive value. CONCLUSIONS The rate of reaching LDL-C target level should be increased in all high risk patients, mainly diabetic ones. Efforts should include educational programs to physicians and patients regarding the importance, the need to adhere and to intensify the cholesterol lowering treatment.

Abstract
OBJECTIVES Submandibular vasodilatory responses are impaired in male streptozotocin-diabetic rats. However, the effects of diabetes on submandibular vascular reactivity in female rats have not been examined. The purpose of this study was to determine whether there are gender differences in the effects of diabetes on parasympathetic vasodilatation in the rat submandibular gland. METHODS Diabetes was induced using streptozotocin, and vascular responses (calculated as the % increase in submandibular vascular conductance) to parasympathetic stimulation (1-10 Hz) were measured using laser-Doppler flowmetry. To estimate the relative contributions of nitric oxide (NO), prostacyclin (PGI2) and endothelium-derived hyperpolarizing factor (EDHF), vascular conductance was measured before and after inhibition of cyclooxygenase (COX) and NO synthase (NOS). RESULTS Frequency-dependent increases in blood flow were observed in both male and female rats, but the contribution of EDHF was greater in females than in males. Further, PGI2 appeared to play a role only in males. Vasodilatory responses were diminished in all diabetic animals, and when compared with their respective controls the degree of impairment was similar in males and females. However, in diabetic males inhibition of COX and NOS had little or no effect, whereas inhibition of NO, but not COX, resulted in a further significant decrease in vascular responses in diabetic females. CONCLUSIONS Parasympathetic vasodilatation in the rat submandibular gland is diminished equally in diabetic males and females. However, in males diabetes predominantly impairs PGI2- and NO-dependent vasodilatation, whereas in females the contribution of EDHF-mediated pathways are affected and NO-dependent vasodilatation is preferentially maintained.

Abstract
PURPOSE The purpose of this study was to evaluate differences in the management of cardiovascular disease (CVD) risk factors based upon the sex of the patient and physician and their interaction in primary care practice. METHODS We evaluated CVD risk factor management in 4,195 patients cared for by 39 male and 16 female primary care physicians in 30 practices in southeastern New England. RESULTS Many of the sex-based differences in CVD risk factor management on crude analysis are lost once adjusted for confounding factors found at the level of the patient, physician, and practice. In multilevel adjusted analyses, styles of CVD risk factor management differed by the sex of the physician, with more female physicians documenting diet and weight loss counseling for hypertension (odds ratio [OR] = 2.22; 95% confidence interval [CI], 1.12-4.40) and obesity (OR = 2.14; 95% CI, 1.30-3.51) and more physical activity counseling for obesity (OR = 2.03; 95% CI, 1.30-3.18) and diabetes (OR = 6.55; 95% CI, 2.01-21.33). Diabetes management differed by the sex of the patient, with fewer women receiving glucose-lowering medications (OR = 0.49; 95% CI, 0.25-0.94), angiotensin-converting enzyme inhibitor therapy (OR = 0.39; 95% CI, 0.22-0.72), and aspirin prophylaxis (OR = 0.30; 95% CI, 0.15-0.58). CONCLUSION Quality of care as measured by patients meeting CVD risk factors treatment goals was similar regardless of the sex of the patient or physician. Selected differences were found in the style of CVD risk factor management by sex of physician and patient.

Abstract
BACKGROUND The incidence of type 2 diabetes is increasing disproportionately in individuals <65 years of age. It is not known whether disease characteristics in these younger patients are similar to "classic" late-onset type 2 diabetes. METHODS In the epidemiological cohort study entitled "Retrolective Study: Self-Monitoring of Blood Glucose and Outcome in Patients with Type 2 Diabetes," a total of 3268 patients from randomly contacted primary care practices were documented during a mean follow-up period of 6.5 years. All newly diagnosed patients of these practices were included. RESULTS At diagnosis, 64.2% of the patients were aged < or =65 years. Thereof, 57.2% were male, whereas in the age group >65 years only 35.0% were male (p < 0.001). The younger group exhibited more severe metabolic deterioration at diagnosis and in the following years than the older group. Conversely, the older group presented at diagnosis with a higher prevalence of cardiovascular risk factors. Self-monitoring of blood glucose (SMBG) was more prominent in the younger group. In both age groups, the use of SMBG was associated with a significantly lower risk (p = 0.003) of a combined end point (severe diabetic complication or all-cause mortality). CONCLUSIONS There are considerable differences in disease characteristics between people diagnosed with type 2 diabetes during 45-65 years of age versus diagnosis at a later age. Type 2 diabetes diagnosed before the age of 65 years disproportionately affected men and exhibited a more severe disease course, but was characterized by significantly less cardiovascular risk factors in comparison to type 2 diabetes diagnosed at a later age. The use of SMBG was associated with a better clinical outcome in both age groups.

Abstract
OBJECTIVE The goal of this study was to investigate gender-specific differences in prevalence, healthcare costs, and treatment patterns in the German Statutory Health Insurance (SHI). METHODS The study analyzed administrative claims data of over 26 million insured with respect to prevalence and cost of illness of six chronic diseases. Insured were identified using the ATC code for medication prescription and ICD-9 code for diagnosis. The influences of gender, age, and comorbidity on cost differences were analyzed via multivariate regression analysis. RESULTS Adjusted for age and comorbidity, gender had a significant influence on both hospital and medication spending. Hospital costs on average were 17.1% (95% CI 14.1; 20.2) higher for men compared with women. Medication spending for men exceeded that for women on average by 13.8% (95% CI 10.9; 16.7). The diagnoses with the highest prevalence were hypertension and heart failure. Women had a higher prevalence of diabetes, coronary artery disease (CAD), heart failure, and hypertension. Medication costs were higher for men in three of five diagnoses and comparable for two diagnoses (diabetes and asthma). Women received more medication prescriptions than men, but on average prescriptions for men were 14%-26% more expensive than prescriptions for women. Regarding treatment patterns men were treated with different drug classes in cardiovascular disease (CVD) compared with women. Total medication spending stratified by diagnosis was highest for diabetes. CONCLUSIONS Gender differences for costs and prescribing patterns for chronic diseases vary disease specifically, but generally men had higher inpatient costs and more expensive medication prescriptions, whereas women had higher numbers of prescriptions.

Abstract
Increased arterial stiffness associated with diabetes and the metabolic syndrome may in part explain the increased cardiovascular disease risk observed in these conditions. Arterial stiffness can be estimated by quantifying pulse pressure but is better described by distensibility and compliance coefficients, pulse wave velocity and wave reflection. The most common non-invasive methodologies used to quantify these estimates of arterial stiffness (e.g. ultrasonography and applanation tonometry) are also described. We then review and summarise the current data on the associations between diabetes, the metabolic syndrome and insulin resistance on the one hand and greater arterial stiffness on the other, and identify and discuss some unresolved issues such as differential stiffening of central vs peripheral arterial segments, the impact of sex, and the pathobiology of increased arterial stiffness in diabetes and the metabolic syndrome. Finally, some considerations with regard to treatment options are presented. At present the most powerful therapy available for reducing arterial stiffness is to vigorously treat hypertension using pharmacological agents. New pharmacological strategies to reduce arterial stiffness are likely to be especially relevant to individuals with diabetes.

Abstract
We studied the effect of varying levels of sex hormones, induced by ovariectomy and administration of testosterone or estradiol, on aortic reactivity in female rats with metabolic syndrome (MS) induced by a sucrose diet. Vasoreactivity of aortic rings, blood pressure, intra-abdominal fat, serum triglycerides, nitrates and nitrites, and TBARS were evaluated. Intact MS and ovariectomized MS had higher BP than intact control (C) and ovariectomized C, respectively; estradiol administration decreased BP in ovariectomized MS but not in ovariectomized C. Triglycerides and fat were both higher in MS. Triglycerides were not modified by surgery or hormone treatment, but ovariectomy increased fat. When ovariectomy was combined with hormones, however, fat was reduced to the level of intact rats. Ovariectomy decreased, but hormones increased, serum nitrates and nitrites. Vasoconstriction was larger in intact MS and ovariectomized MS + testosterone aortas than in intact C and ovariectomized C + testosterone, respectively. Vasodilation was reduced in intact MS and ovariectomized MS + testosterone compared with intact C, ovariectomized C + testosterone, ovariectomized MS, and ovariectomized MS + estradiol. The results suggest endothelial dysfunction in intact MS and ovariectomized MS + testosterone, but protection by ovariectomy + estradiol in MS due to hormones. Indomethacin reduced all contractions, but the effect was greater in estradiol-treated rats. l-NAME increased contractility, more in the ovariectomized C and MS groups and less in the estradiol-treated groups.

Abstract
Several experimental models have so far been developed to improve our knowledge of the pathogenetic mechanisms of type 2 diabetes mellitus (T2D), to determine the possible pharmacological targets of this disease and to better evaluate diabetes-associated complications, e.g. the cardiovascular disease. In particular, the study of T2D gained the attention of several groups working with different animal species: rodents, cats or pigs, as well as other non-human primate species. Each of these species provided useful and different clues. However, T2D has to be considered as a gender-associated disease: sex differences play in fact a key role in the onset as well as in the progression of the disease and a higher mortality for cardiovascular diseases is detected in diabetic women with respect to men. The results obtained from all the available animal models appear to only partially address this issue so that the search for more precise information in this respect appears to be mandatory. In this review we summarize these concepts and literature in the field and propose a reappraisal of the various animal models for a study of T2D that would take into consideration a gender perspective.

Abstract
The metabolic syndrome is estimated to be present in 47 million US residents with a similar age-adjusted prevalence in men (24%) and women (23%). The consideration of various metabolic risk factors as a single entity in the metabolic syndrome provides clinicians with a tool by which they can identify a population at increased risk for type 2 diabetes mellitus and increased cardiovascular morbidity and mortality. Cardiovascular disease is the leading cause of mortality in women in the US. To reduce the risk of cardiovascular disease, efforts have focused on modifying the metabolic risk factors that constitute the metabolic syndrome: abdominal obesity, dyslipidemia, glucose intolerance, and hypertension. In addition, because of several circumstances specific to women, including pregnancy, polycystic ovary syndrome, oral contraceptive therapy use, and menopause, there are special considerations regarding risk factor identification, modification, and clinical management. This article provides a review of diagnostic and therapeutic issues that clinicians should consider when caring for women at risk for developing or diagnosed with the metabolic syndrome.

Abstract
BACKGROUND Low heart rate recovery (HRR) at exercise test and the metabolic syndrome (MetS) are both predictors of cardiovascular morbidity and mortality. We studied in 75-year-old women and men, representative of the general population, the relationship between (1) HRR and the MetS, (2) HRR and the individual components of the MetS, and (3) HRR and insulin sensitivity. METHODS A cross-sectional study of randomly selected 75-year-olds from a general population was performed (191 women and 194 men). The MetS was defined according to the National Cholesterol Education Program criteria. Heart rate was measured as beats per minute immediately after exercise and at 4 minutes into recovery. RESULTS Heart rate recovery (median and interquartile range, beat/min) was 48 (37-58) for women and 49 (38-58) for men. Thirty-seven percent of the women and 25% of the men had the MetS. Heart rate recovery was 52 (42-61) for women with the MetS and 42 (31-49) for those without. The corresponding values for men was 50 (39-61) and 47 (35-54); the difference between individuals with and without the MetS was significant for women (P < .001) but not for men (P = .084). The following significant correlation coefficients between HRR and MetS components were found: for women, waist circumference (-0.43, P < .001), high-density lipoprotein cholesterol (0.37, P < .001), insulin sensitivity (-0.37, P < .001), fasting plasma glucose (-0.30, P < .001), and triglycerides (-0.24, P = .001); for men, triglycerides (-0.20, P = .005). The sex disparity in the strength of correlation reached statistical significance for insulin sensitivity (P < .001) and waist circumference (P = .042). CONCLUSION Among 75-year-olds, the MetS and related components are more strongly correlated to HRR in women than in men.

Abstract
The effects of the antihypertensive drugs on carbohydrate metabolism and the development of diabetes have been a major research field for more than two decades. Many clinical studies have investigated the effects of the antihypertensive classes on insulin sensitivity and glycemic control, whereas several observational studies and large outcome trials have examined associations of antihypertensive agents with diabetes incidence. In general, thiazide diuretics and conventional beta blockers decrease insulin sensitivity and increase new-onset diabetes, whereas angiotensin-converting enzyme inhibitors, calcium channel blockers, and angiotensin II receptor blockers have neutral or beneficial effects on these parameters. However, several issues in this field, such as the specific properties of newer agents and the relationship of adverse metabolic outcomes and cardiovascular risk, remain to be fully elucidated. This article presents and evaluates the current knowledge in this important area.

Abstract
Sex is a significant epidemiological factor for several diseases. However, the role of sex in the development and outcome of various infections has not been extensively studied with the notable exception of urinary tract infections. We searched in the PubMed database to identify articles that could provide relevant data regarding sex differences in the incidence and severity of respiratory tract infections (RTIs). We extracted data from 84 relevant studies that provided information regarding sex differences in the incidence and severity of RTIs. Females are more commonly affected with infections of the upper respiratory tract, specifically sinusitis, tonsillitis, and otitis externa. On the other hand, males are more commonly affected with otitis media, croup, and most important, lower RTIs. It is also evident from the reviewed evidence that the course of most RTIs is more severe in males than in females, leading to higher mortality in males, especially in community-acquired pneumonia. In conclusion, the available data suggest that males are more susceptible than females to most types of RTIs in all age groups (adults and children). Overall, it seems that males develop RTIs more frequently than females, except for sinusitis, otitis externa, and probably tonsillitis. Anatomic, lifestyle, behavioural, and socioeconomic differences between males and females may explain the observed findings. The role of sex hormones in the regulation of the immune system may also contribute to the reported sex differences in the incidence and severity of the various types of RTIs, especially in adolescents and adults.

Abstract
OBJECTIVES This study aimed to investigate whether the clustering of the risk factors of the metabolic syndrome (MetS) is associated with stiffness of central and peripheral arterial segments; whether these associations are similar in men and women; and whether insulin resistance and low-grade inflammation mediate any such associations. BACKGROUND Increased arterial stiffness may explain, at least in part, the increased cardiovascular and diabetes risk associated with the MetS. However, the mechanisms linking the MetS to an increased arterial stiffness are incompletely understood, and gender differences may exist. METHODS Cross-sectional analyses of data on 313 young men and women (mean age 23 years) from the Northern Ireland Young Hearts Project. Subjects were categorized according to the number of traits of the MetS; in addition a continuous MetS score was calculated. Arterial stiffness was assessed by measuring pulse wave velocity (PWV) in three arterial segments using a non-invasive optical method. RESULTS The prevalence of the MetS was similar for men (10.6%) and women (10.5%). After adjustment for potential confounders and other cardiovascular risk factors, PWV of the three arterial segments investigated increased with increasing traits of the MetS in women only. Women with the MetS, as compared to those without risk factors of the syndrome, had greater PWV of the aorto-iliac (+14.0%, P = 0.016), the aorto-radial (+13.2%, P = 0.010) and aorto-dorsalis pedis (+11.8%, P = 0.011) segments. A great deal (up to 75%) of the association between the MetS and aortic-iliac PWV was mediated by heart rate, inflammation markers [C-reactive protein (CRP) and fibrinogen] and insulin resistance [homeostatic model assessment-insulin resistance (HOMA-IR)], whereas these variables did not explain much of the association between the MetS and PWV of the peripheral segments. CONCLUSIONS Young women with the MetS show increased stiffness of peripheral and central arteries, a mechanism that may explain their increased cardiovascular risk. Low-grade inflammation, insulin resistance and sympathetic activation explain much of the adverse impact of the MetS on central, but not peripheral, arterial stiffness.
