Zn is an essential mineral. The role of Zn in atherosclerosis is not clear. Epidemiological studies, which have reported contradictory results, are limited by the use of serum Zn levels as a marker of intake. We assessed the association of toenail Zn, which integrates dietary Zn intake over 3 to 12 months, with the risk of a first myocardial infarction. Toenail Zn concentrations were determined by neutron activation analysis in the European multi-centre case–control study on antioxidants, myocardial infarction and breast cancer. This multi-centre case–control study included 684 cases and 724 controls from eight European countries and Israel. Toenail Zn levels of controls (adjusted for age and study centre) were positively associated with age, α-tocopherol and Se, but not with additional dietary variables or with classical risk factors for CHD. Average toenail Zn was 106·0 mg/kg in cases (95 % CI 103·1, 108·9) and 107·5 mg/kg in controls (95 % CI 104·5, 110·7). After controlling for cardiovascular risk factors and for centre, the adjusted odds ratios of myocardial infarction for quintiles 2–5 of toenail Zn with respect to the first quintile were 0·97 (95 % CI 0·59, 1·58), 1·15 (95 % CI 0·72, 1·85), 0·91 (95 % CI 0·56, 1·50), and 0·85 (95 % CI 0·52, 1·39). ThePfor trend was 0·45. In conclusion toenail Zn levels (reflecting long-term dietary intake) were not significantly associated with acute myocardial infarction.

Abstract Background In recent years, there has been an increasing incidence of community-acquired urinary tract infections (UTI) caused by extended-spectrum β-lactamase (ESBL) producing Escherichia coli. However, the risk factors of ESBL-producing bacteria in community-acquired (CA)-UTI in children in the USA remain unclear. Methods A retrospective case–control study of UTI due to CA-ESBL-producing E. coli during a 5-year period (2011–2016) was performed. Control cases of non-ESBL-producing E. coli UTI were matched by age, gender, and year of infection. Medical records were manually reviewed to collect data for potential risk factors for ESBL-positive infection. Results A total of 111 patients with ESBL-producing E coli UTI and 103 control patients were included. The proportion of ESBL-producing E coli UTI ranged from 7% to 15% per year. The median age was 4 years with female predominance (84%). The ESBL group was predominantly African American (32%) followed by patients of Middle Eastern (ME) ethnic background (31%). Risk factors by univariate analysis were vesicoureteral reflux (VUR): (20.9 ESBL group vs. 6% controls; P = 0.002), prior antibiotic usage in the previous 3 months (including β-lactams), prior UTI (last 3 months), recent hospitalization (last 3 months) and ME ethnic background. However, multivariate analysis showed that only prior antibiotic usage (P = 0.001) and ME ethnic background (P < 0.001) remained statistically significant. 18% (11/60) of patients exposed to prior antibiotic use in the ESBL group were on long-term antibiotic prophylaxis for VUR. Conclusion Risk factors for CA-ESBL-producing E coli UTI in children were: (1) antibiotic usage within the previous 3 months and (2) ME background. Prior antibiotic usage as a risk factor reinforces the need for judicious use of antibiotics. The high percentage of patients in this group (18%) receiving long-term antibiotic prophylaxis for VUR warrants further study as this practice may increase the prevalence of ESBL-producing infections in a population at high risk for UTI. The increased risk among children of ME ethnic background warrants further study to evaluate possible additional associated risk factors such as recent international travel or contact with international travelers.
