Childhood Exposure to Phthalates: Associations with Thyroid Function,Insulin-like Growth Factor I,and Growth

Background

Phthalates are widely used chemicals, and human exposure is extensive. Recent studies have indicated that phthalates may have thyroid-disrupting properties.

Objective

We aimed to assess concentrations of phthalate metabolites in urine samples from Danish children and to investigate the associations with thyroid function, insulin-like growth factor I (IGF-I), and growth.

Methods

In 845 children 4–9 years of age, we determined urinary concentrations of 12 phthalate metabolites and serum levels of thyroid-stimulating hormone, thyroid hormones, and IGF-I.

Results

Phthalate metabolites were detected in all urine samples, of which monobutyl phthalate was present in highest concentration. Phthalate metabolites were negatively associated with serum levels of free and total triiodothyronine, although statistically significant primarily in girls. Metabolites of di(2-ethylhexyl) phthalate and diisononyl phthalate were negatively associated with IGF-I in boys. Most phthalate metabolites were negatively associated with height, weight, body surface, and height gain in both sexes.

Conclusions

Our study showed negative associations between urinary phthalate concentrations and thyroid hormones, IGF-I, and growth in children. Although our study was not designed to reveal the mechanism of action, the overall coherent negative associations between urine phthalate and thyroid and growth parameters may suggest causative negative roles of phthalate exposures for child health.

Dietary sodium and potassium in the genesis,therapy, and prevention of hypertension.

In this review, we first summarized the evidence from animals and man for and against a role for dietary sodium in the genesis and treatment of hypertension. The evidence for a role for dietary sodium in the genesis of hypertension is strongest in those subjects with impaired ability to excrete sodium due to organic renal disease or mineralocorticoid excess. Here restriction of dietary sodium promptly lowers arterial pressure. Its role in the genesis of essential hypertension is still controversial. Nevertheless, it appears that some patients with mild to moderate essential hypertension respond to moderate sodium restriction with a modest fall in blood pressure. This restriction also seems to reduce the amount of antihypertensive medication needed to keep blood pressure under control. We next considered the mechanism of the pressure response to dietary sodium chloride, concentrating upon the increase in extracellular fluid volume, potassium depletion, and increased plasma levels of prohypertensive sodium pump inhibitor and antihypertensive atrial natriuretic factor. We next summarized the evidence for a primary role for dietary potassium in the genesis of hypertension and pointed out that certain subsets of subjects with a high incidence of hypertension also have a lower dietary potassium intake. Some investigators find that dietary potassium supplementation lowers blood pressure in established hypertension. This may result from natriuresis and from vasodilation subsequent to stimulation of Na+, K+-ATPase in vascular smooth muscle and adrenergic nerve terminals. We then considered practical aspects of dietary sodium restriction and dietary potassium supplementation in the therapy for established hypertension. The review concludes with comments on their possible roles in the prevention of hypertension.

Physical Activity, Inflammation, and Muscle Loss

Sarcopenia is the degenerative loss of skeletal muscle that occurs naturally in individuals as they age. Although many factors underlie sarcopenia, epidemio-logical and experimental evidence suggests that low-grade chronic inflammation is an important contributor to its progression. Still, few healthcare professionals have a clear understanding of the profound effects of cytokines on sarcopenia, or how these effects may be counteracted. Interestingly, mounting evidence suggests that along with good diet and vitamin supplementation, this muscle damage can be mitigated with regular physical activity. Without a doubt, exercise is an intervention that reliably counteracts the loss of muscle mass, strength, and power common in our increasingly aged, and pervasively sedentary, population.     

Blood Lead Levels and Serum Insulin-Like Growth Factor 1 Concentrations in Peripubertal Boys

Background: Childhood lead exposure has been associated with growth delay. However, the association between blood lead levels (BLLs) and insulin-like growth factor 1 (IGF-1) has not been characterized in a large cohort with low-level lead exposure.Methods: We recruited 394 boys 8–9 years of age from an industrial Russian town in 2003–2005 and followed them annually thereafter. We used linear regression models to estimate the association of baseline BLLs with serum IGF-1 concentration at two follow-up visits (ages 10–11 and 12–13 years), adjusting for demographic and socioeconomic covariates.Results: At study entry, median BLL was 3 μg/dL (range, < 0.5–31 μg/dL), most boys (86%) were prepubertal, and mean ± SD height and BMI z-scores were 0.14 ± 1.0 and –0.2 ± 1.3, respectively. After adjustment for covariates, the mean follow-up IGF-1 concentration was 29.2 ng/mL lower (95% CI: –43.8, –14.5) for boys with high versus low BLL (≥ 5 μg/dL or < 5 μg/dL); this difference persisted after further adjustment for pubertal status. The association of BLL with IGF-1 was stronger for mid-pubertal than prepubertal boys (p = 0.04). Relative to boys with BLLs < 2 μg/dL, adjusted mean IGF-1 concentrations decreased by 12.8 ng/mL (95% CI: –29.9, 4.4) for boys with BLLs of 3–4 μg/dL; 34.5 ng/mL (95% CI: –53.1, –16.0) for BLLs 5–9 μg/dL; and 60.4 ng/mL (95% CI: –90.9, –29.9) for BLLs ≥ 10 μg/dL.Conclusions: In peripubertal boys with low-level lead exposure, higher BLLs were associated with lower serum IGF-1. Inhibition of the hypothalamic–pituitary–growth axis may be one possible pathway by which lead exposure leads to growth delay.     

Application of a Machine Learning Technology in the Definition of Metabolically Healthy and Unhealthy Status: A Retrospective Study of 2567 Subjects Suffering from Obesity with or without Metabolic Syndrome

The key factors playing a role in the pathogenesis of metabolic alterations observed in many patients with obesity have not been fully characterized. Their identification is crucial, and it would represent a fundamental step towards better management of this urgent public health issue. This aim could be accomplished by exploiting the potential of machine learning (ML) technology. In a single-centre study (n = 2567), we used an ML analysis to cluster patients with metabolically healthy (MHO) or metabolically unhealthy (MUO) obesity, based on several clinical and biochemical variables. The first model provided by ML was able to predict the presence/absence of MHO with an accuracy of 66.67% and 72.15%, respectively, and included the following parameters: HOMA-IR, upper body fat/lower body fat, glycosylated haemoglobin, red blood cells, age, alanine aminotransferase, uric acid, white blood cells, insulin-like growth factor 1 (IGF-1) and gamma-glutamyl transferase. For each of these parameters, ML provided threshold values identifying either MUO or MHO. A second model including IGF-1 zSDS, a surrogate marker of IGF-1 normalized by age and sex, was even more accurate with a 71.84% and 72.3% precision, respectively. Our results demonstrated high IGF-1 levels in MHO patients, thus highlighting a possible role of IGF-1 as a novel metabolic health parameter to effectively predict the development of MUO using ML technology.
