RESUMEN
AIM: We aimed to study sex differences in long-term survival following out-of-hospital cardiac arrest (OHCA) compared to the general population, and determined associations for comorbidities, social characteristics, and resuscitation characteristics with survival in women and men separately. METHODS: We followed 2,452 Danish (530 women and 1,922 men) and 1,255 Dutch (259 women and 996 men) individuals aged ≥25 years, who survived 30 days post-OHCA in 2009-2015, until 2019. Using Poisson regression analyses we assessed sex differences in long-term survival and sex-specific associations of characteristics mutually adjusted, and compared survival with an age- and sex-matched general population. The potential predictive value was assessed with the Concordance-index. RESULTS: Post-OHCA survival was longer in women than men (adjusted incidence rate ratio (IRR) for mortality 0.74, 95%CI 0.61-0.89 in Denmark; 0.86, 95%CI 0.65-1.15 in the Netherlands). Both sexes had a shorter survival than the general population (e.g., IRR for mortality 3.07, 95%CI 2.55-3.70 and IRR 2.15, 95%CI 1.95-2.37 in Danish women and men). Higher age, glucose lowering medication, no dyslipidaemia medication, unemployment, and a non-shockable initial rhythm were associated with shorter survival in both sexes. Cardiovascular medication, depression/anxiety medication, living alone, low household income, and residential OHCA location were associated with shorter survival in men. Not living with children and bystander cardiopulmonary resuscitation provision were associated with shorter survival in women. The Concordance-indexes ranged from 0.51 to 0.63. CONCLUSIONS: Women survived longer than men post-OHCA. Several characteristics were associated with long-term post-OHCA survival, with some sex-specific characteristics. In both sexes, these characteristics had low predictive potential.

AIM: Women have less favorable resuscitation characteristics than men. We investigated whether the Advanced Life Support Termination of Resuscitation rule (ALS-TOR) performs equally in women and men. Additionally, we studied whether adding or removing criteria from the ALS-TOR improved classification into survivors and non-survivors. METHODS: We analyzed 6,931 female and 14,548 male out-of-hospital cardiac arrest (OHCA) patients from Dutch and Swedish registries, and validated in 10,772 female and 21,808 male Danish OHCA patients. Performance measures were calculated for ALS-TOR in relation to 30-day survival. Recursive partitioning analysis was performed with the ALS-TOR criteria, as well as age, comorbidities, and additional resuscitation characteristics (e.g. initial rhythm, OHCA location). Finally, we explored if we could reduce the number of ALS-TOR criteria without loss of prognostic value. RESULTS: The ALS-TOR had a specificity and positive predictive value (PPV) of ≥99% in both women and men (e.g. PPV 99.9 in men). Classification by recursive partitioning analysis showed a high sensitivity but a PPV below 99%, thereby exceeding the acceptable miss rate of 1%. A combination of no return of spontaneous circulation (ROSC) before transport to the hospital and unwitnessed OHCA resulted in nearly equal specificity and PPV, higher sensitivity, and a lower transport rate to the hospital than the ALS-TOR. CONCLUSION: For both women and men, the ALS-TOR has high specificity and low miss rate for predicting 30-day OHCA survival. We could not improve the classification with additional characteristics. Employing a simplified version may decrease the number of futile transports to the hospital.

BACKGROUND: Women at risk of cardiovascular disease (CVD) may be missed with current eligibility criteria for CVD risk screening, particularly those from ethnic minority groups, among whom high risk is prevalent at a younger age. Early menopause (EM; menopause before 45 years) is associated with increased risk of CVD, and may be a potential eligibility criterion for CVD risk screening. AIMS AND OBJECTIVES: To determine the contribution of EM to current criteria from patient history (having a family history of CVD, current smoking, obesity and age over 50 years) for identifying women eligible for CVD risk screening in a multi-ethnic population. METHODS AND RESULTS: We used baseline data (2011-2015) from 4512 women aged 45-70 years of Dutch, South-Asian Surinamese, African Surinamese, Ghanaian, Turkish and Moroccan ethnic origin from the HELIUS study (Amsterdam, Netherlands). Models based on current eligibility criteria with and without EM were compared on area under the curve (AUC) with regard to estimated 10-year CVD risk using the Dutch SCORE. Overall, models with EM had a higher AUC, but changes were not statistically significant. In our total sample of women aged between 45 and 70 years, the AUC changed from 0.70 (95%CI 0.69-0.72) to 0.71 (95%CI 0.69-0.72). Among women aged 45-50 years the AUC changed from 0.66 (95%CI 0.58-0.74) to 0.68 (95%CI 0.59-0.74). Results were consistent across ethnic groups. CONCLUSIONS: The addition of EM to current eligibility criteria did not improve the detection of women at high CVD risk in a multi-ethnic sample of women aged 45-70 years.

AIMS: We aimed to describe differences in the prevalence of intermediate hyperglycaemia (IH) between six ethnic groups. Moreover, to investigate differences in the association of the classifications of IH with the incidence of T2DM between ethnic groups. METHODS: We included 3759 Dutch, 2826 African Surinamese, 1646 Ghanaian, 2571 Turkish, 2691 Moroccan and 1970 South Asian Surinamese origin participants of the HELIUS study. IH was measured by fasting plasma glucose (FPG) and HbA1c. We calculated age-, BMI and physical-activity-adjusted prevalence of IH by sex, and calculated age and sex-adjusted hazard ratios (HR)for the association between IH and T2DM in each ethnic group. RESULTS: The prevalence of IH was higher among ethnic minority groups (68.6-41.7%) than the Dutch majority (34.9%). The prevalence of IH categories varied across subgroups. Combined increased FPG and HbA1c was most prevalent in South-Asian Surinamese men (27.6%, 95 %CI: 24.5-30.9%), and in Dutch women (4.2%, 95 %CI: 3.4-5.1%). The HRs for T2DM for each IH-classification did not differ significantly between ethnic groups. HRs were highest for the combined classification, e.g., HR = 8.1, 95 %CI: 2.5-26.6 in the Dutch. CONCLUSION: We found a higher prevalence of IH in ethnic minority versus majority groups, but did not find evidence for a differential association of IH with incident T2DM.

BACKGROUND: Recently, cardiovascular disease (CVD) research has focused on sex- and gender-related cardiovascular risk factors, in addition to conventional risk factors. This raises the question which factors are perceived by the target group (patients with CVD) as priorities for further research. METHODS: We carried out a survey to study priority setting for more research into conventional and sex- and gender-related risk factors according to 980 men and women with CVD or those at increased risk of CVD in the Netherlands. Data on conventional and sex- and gender-related risk factors were descriptively analysed, stratified by gender group. RESULTS: The most frequently prioritised conventional factors according to men were heritability, overweight and unhealthy diet, while women most frequently listed stress, heritability and hypertension. The most frequently prioritised sex- and gender-related risk factors were depression or depressive feelings, migraine and having many caretaking responsibilities (men), and pregnancy complications, contraceptive pill use and early age at menopause (women). New research on sex- and gender-related risk factors was perceived roughly as relevant as that on conventional factors by men (mean 7.4 and 8.3 on a 1-10 scale, respectively) and women (8.2 and 8.6, respectively). Ethnic and gender minority groups placed more emphasis on risk factors related to sociocultural aspects (gender) than the majority group. CONCLUSION: Men and women with CVD or those at increased risk of CVD perceived new research on conventional and sex- and gender-related risk factors as a priority. These findings may guide researchers and funders in further prioritising new CVD research.
RESUMEN
BACKGROUND AND AIMS: Cardiovascular disease (CVD) risk factors may occur among a substantial proportion of normal weight individuals, particularly among some ethnic minorities. It is unknown how many of these individuals would be missed by commonly applied eligibility criteria for cardiovascular risk screening. Thus, we aim to determine cardiovascular risk and eligibility for cardiovascular risk screening among normal weight individuals of different ethnic backgrounds. METHODS AND RESULTS: Using the HELIUS study (Amsterdam, The Netherlands), we determined cardiovascular risk among 6910 normal weight individuals of Dutch, South-Asian Surinamese, African Surinamese, Ghanaian, Moroccan and Turkish background. High cardiovascular risk was approximated by high metabolic risk based on blood pressure, HDL, triglycerides and fasting glucose. Eligibility criteria for screening were derived from Dutch CVD prevention guidelines and include age ≥ 50 y, family history of CVD, or current smoking. Ethnic group comparisons were made using logistic regression. Age-adjusted proportions of high metabolic risk ranged from 12.6% to 38.4% (men) and from 2.7% to 11.5% (women). This prevalence was higher among most ethnic minorities than the Dutch, especially among women. For most ethnic groups, 79.9%-86.7% of individuals with high metabolic risk were eligible for cardiovascular risk screening. Exceptions were Ghanaian women (58.8%), Moroccan men (70.9%) and Moroccan women (45.0%), although age-adjusted proportions did not differ between groups. CONCLUSION: Even among normal weight individuals, high cardiovascular metabolic risk is more common among ethnic minorities than among the majority population. Regardless of ethnicity, most normal weight individuals with increased risk are eligible for cardiovascular risk screening.

AIMS: Evidence of ethnic disparities in the conversion of prediabetes to type 2 diabetes is scarce. We studied the association of impaired fasting glucose (IFG) and fasting plasma glucose (FPG) with the 10-year cumulative incidence of type 2 diabetes in three ethnic groups. METHODS: We analyzed data for 90 South-Asian Surinamese, 190 African-Surinamese, and 176 ethnic Dutch that were collected in the periods 2001-2003 and 2011-2012. We excluded those with type 2 diabetes or missing FPG data. We defined baseline IFG as FPG of 5.7-6.9 mmol/L. We defined type 2 diabetes at follow-up as FPG ≥ 7.0 mmol/L, HbA1c ≥ 48 mmol/mol (6.5%), or self-reported type 2 diabetes. RESULTS: 10-Year cumulative incidences of type 2 diabetes were: South-Asian Surinamese, 18.9%; African-Surinamese, 13.7%; ethnic Dutch, 4.5% (p<0.05). The adjusted association of baseline IFG and FPG with the 10-year cumulative incidence of type 2 diabetes was stronger for South-Asian Surinamese than for African-Surinamese and ethnic Dutch. The IFG (compared to normoglycaemia) ORs were 11.1 [3.0-40.8] for South-Asian Surinamese, 5.1 [2.0-13.3] for African-Surinamese, and 2.2 [0.5-10.1] for ethnic Dutch. CONCLUSIONS: The 10-year cumulative incidence of type 2 diabetes was higher and associations with baseline IFG and FPG were stronger among South-Asian Surinamese and African-Surinamese than among ethnic Dutch. Our findings confirm the high risk of type 2 diabetes in South-Asians and suggest more rapid conversion in populations of South-Asian origin and (to a lesser extent) African origin than European origin.

AIMS: To study differences in the association between physical inactivity and Type 2 diabetes among subjects from different ethnic groups. METHODS: We analysed data on 508 Caucasian, 596 African-Surinamese and 339 Hindustani-Surinamese participants, aged 35-60 years, in the population-based, cross-sectional Surinamese in the Netherlands Study on Health and Ethnicity (SUNSET) study. Physical inactivity was defined as the lowest quartile of reported activity, measured with the validated Short Questionnaire to Assess Health-Enhancing Physical Activity. Type 2 diabetes was defined as fasting plasma glucose levels ≥7.0 mmol/l or self-reported diagnosis. RESULTS: Physical inactivity was associated with Type 2 diabetes (OR 1.63, 95% CI 1.12-2.38) in the total group after adjustment for sex, age, BMI, ethnicity, resting heart rate, hypertension, smoking, history of cardiovascular disease, having a first-degree relative with Type 2 diabetes and educational level. However, this association was only significant in Caucasians (OR 3.17, 95% CI 1.37-7.30). Moreover, it appeared stronger in Caucasians than in Hindustani-Surinamese (OR 1.43, 95% CI 0.78-2.63) and African-Surinamese (OR 1.13, 95% CI 0.58-2.19), although the P-value for interaction was not significant. CONCLUSIONS: Physical inactivity was associated with Type 2 diabetes in the total group after adjustment for multiple risk factors, but this association was only significant in Caucasians. Also, it appeared stronger in Caucasians than in Hindustani and African-Surinamese, but formal testing for interaction provided no further evidence. These findings confirm the importance of exercise, but suggest that potential health gain may differ between ethnic groups. However, it should be noted that, in general, promotion of physical activity in populations with an increased a priori risk of Type 2 diabetes, remains of the utmost importance.

We investigated the frequency of the 5/5 homozygous CNDP1 (carnosinase) genotype, which was found to be associated with a reduced risk of developing diabetic nephropathy, in three ethnic groups in The Netherlands. Particularly interesting were the South Asian Surinamese, who have a high prevalence of diabetic nephropathy. Furthermore, we investigated the association between this gene and carnosinase activity in South Asian Surinamese and whether carnosinase was expressed in the kidney. We genotyped 290 South Asian Surinamese, 532 African Surinamese, and 472 White Dutch in a cross-sectional population study. Furthermore, an independent cohort of South Asian Surinamese was genotyped. In this population, carnosinase activity was measured in serum. Immunostaining and in situ hybridization for CNDP1 were performed on kidney tissue. Both South Asian populations had lower frequencies of the 5/5 homozygous genotype than African Surinamese and White Dutch (23.0%, 27.2%, 38.2%, and 41.3%, respectively; chi-square, p<0.001). This genotype showed a lower carnosinase activity in South Asian Surinamese (Wilcoxon rank-sum, p=0.03). CNDP1 was expressed in the kidney. South Asian Surinamese have a lower frequency of the 5/5 homozygous genotype, which was associated with lower carnosinase activity. Our study provides an indication that South Asian Surinamese are genetically at risk for developing diabetic nephropathy.

We used a population based study in the Netherlands of 330 Hindustani Surinamese, 586 African Surinamese, and 486 ethnic Dutch (Dutch) to describe the prevalence of the metabolic syndrome (MS) and the association with differences in cardiovascular disease in and between ethnic groups. Fasting blood samples, blood pressure, and anthropometric measurements were obtained. MS was defined according to the criteria of the International Diabetes Federation (IDF) and the criteria of the National Cholesterol Education Program (NCEP). Cardiovascular disease was assessed by the Rose questionnaire and included questions on previous diagnoses of angina pectoris/myocardial infarction, cerebrovascular accident, intermittent claudication. The prevalence of MS (IDF and NCEP) was highest in Hindustani Surinamese men, followed by Dutch and African Surinamese men: 51.0%, 19.4%, and 31.2% (IDF), respectively. Among women, both the Hindustani and African Surinamese participants had a higher prevalence of MS (IDF and NCEP) than the Dutch. The association between the components, MS and cardiovascular disease differed between ethnic groups, in particular among men; OR for MS (NCEP) = 1.0 (0.4-2.7) among Hindustani Surinamese, OR = 4.9 (1.3-18.3) among African Surinamese, and OR = 2.8 (1.1-7.1) among Dutch. However, the differences in MS could not account for the ethnic differences in cardiovascular disease, regardless of the criteria used. The results suggest that, before the criteria can be used to guide practice, they may need to be changed and refined to take into account the differences between ethnic groups as well as the variations by gender.
