Early weaning is beneficial to prevent atopic dermatitis occurrence in young children
Abstract
Background
Epidemiological data on infant feeding practices and allergic diseases are controversial. The purpose of this study was to explore the association of early weaning with the occurrence of atopic dermatitis (AD).
Methods
We conducted a matched case-control study on incident physician-diagnosed AD in early childhood including 451 cases and 451 controls. Data on several factors, including feeding practices, were collected through an interviewer-administered questionnaire. Odds ratios (OR) and the corresponding 95% confidence intervals (CI) were estimated through logistic regression models, conditioned on study center, age, sex, and period of interview, and adjusted for potential confounders.
Results
Early weaning, defined as the introduction of solid foods at 4 or 5 months of age, was inversely related to the risk of AD, with children weaned at 4 months having lower AD risk (OR=0.41, 95% CI, 0.20-0.87) compared to those exclusively breastfed. Similar results were observed for weaning started at 5 months of age (OR=0.39, 95% CI, 0.18-0.83). This association persisted when children with and without family history of allergy were considered. Prolonged partial breastfeeding (breast-milk plus milk formulas and/or solid food) was not associated to AD. Consistently, the introduction of a high number of different solid foods reduced the risk of AD (p trend= 0.02 at 4 months of age and p trend= 0.04 at 5 months).
Conclusion
Our data provide evidence against the preventing role of prolonged exclusive (but not partial) breastfeeding on AD occurrence, and confirms recent results indicating a beneficial role of early weaning on AD.

Changes in Parent-Child Relationship Quality Across Early Adolescence:: Implications for Engagement in Sexual Behavior
The present study investigated how changes in specific dimensions of the parent–adolescent relationship predict adolescent engagement in sexual intercourse and oral sex. Longitudinal data from 1,364 participants in the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development were gathered at six time points spanning from first grade to age 15. Latent growth curve modeling was used to investigate whether changes in mother–adolescent and father–adolescent closeness or conflict predicted adolescents’ sexual behavior at age 15. Results indicate that more rapid increase in mother–adolescent conflict predicted engagement in sexual intercourse but not oral sex by age 15, whereas change in mother–adolescent closeness did not predict sexual behaviors. A more rapid decline in father–adolescent closeness and a more rapid increase in father–adolescent conflict predicted more engagement in sexual behaviors by age 15.

Enduring Egalitarianism? Family Transitions and Attitudes Toward Gender Equality in Sweden
Previous research in industrialized countries finds that attitudes toward gender equality are affected by family-related transitions as young adults with egalitarian attitudes based on growing equality between the sexes in the public sphere of education and work encounter a much less equal situation in the private sphere of the family. Sweden, however, is a society known for its emphasis on gender equality in the family. This study examines the effect of family transitions on attitudes toward gender equality, asking whether egalitarian attitudes can withstand changing family transitions in Sweden. Using longitudinal data from the Young Adult Panel Study, we examine six different family transitions and three measures of attitudes toward gender equality for men and women, with only three significant findings across 18 coefficients. We conclude that most Swedish young adults possess "enduring attitudes," likely because there is strong state support for families and gender sharing in the private sphere.

Association between cytoplasmic CRABP2, altered retinoic acid signaling, and poor prognosis in glioblastoma
ABSTRACT
Retinoic acid (RA), a metabolite of vitamin A, is required for the regulation of growth and development. Aberrant expression of molecules involved in RA signaling has been reported in various cancer types including glioblastoma multiforme (GBM). Cellular retinoic acid-binding protein 2 (CRABP2) has previously been shown to play a key role in the transport of RA to retinoic acid receptors (RARs) to activate their transcription regulatory activity. Here, we demonstrate that CRABP2 is predominantly located in the cytoplasm of GBM tumors. Cytoplasmic, but not nuclear, CRABP2 levels in GBM tumors are associated with poor patient survival. Treatment of malignant glioma cell lines with RA results in a dose-dependent increase in accumulation of CRABP2 in the cytoplasm. CRABP2 knockdown reduces proliferation rates of malignant glioma cells, and enhances RA-induced RAR activation. Levels of CRYAB, a small heat shock protein with anti-apoptotic activity, and GFAP, an astrocyte-specific intermediate filament protein, are greatly reduced in CRABP2-depleted cells. Restoration of CRYAB expression partially but significantly reversed the effect of CRABP2 depletion on RAR activation. Our combined in vivo and in vitro data indicate that: (i) CRABP2 is an important determinant of clinical outcome in GBM patients, and (ii) the mechanism of action of CRABP2 in GBM involves sequestration of RA in the cytoplasm and activation of an anti-apoptotic pathway, thereby enhancing proliferation and preventing RA-mediated cell death and differentiation. We propose that reducing CRABP2 levels may enhance the therapeutic index of RA in GBM patients. GLIA 2016.
Main points
- Cytoplasmic CRABP2 in glioblastoma (GBM) tumors is associated with poor prognosis
- CRABP2 accumulates in the cytoplasm of retinoic acid-treated GBM cells and attenuates RA signaling

Chronic exposure to air pollution particles increases the risk of obesity and metabolic syndrome: findings from a natural experiment in Beijing [Research]
Epidemiologic evidence suggests that air pollution is a risk factor for childhood obesity. Limited experimental data have shown that early-life exposure to ambient particles either increases susceptibility to diet-induced weight gain in adulthood or increases insulin resistance, adiposity, and inflammation. However, no data have directly supported a link between air pollution and non-diet-induced weight increases. In a rodent model, we found that breathing Beijing’s highly polluted air resulted in weight gain and cardiorespiratory and metabolic dysfunction. Compared to those exposed to filtered air, pregnant rats exposed to unfiltered Beijing air were significantly heavier at the end of pregnancy. At 8 wk old, the offspring prenatally and postnatally exposed to unfiltered air were significantly heavier than those exposed to filtered air. In both rat dams and their offspring, after continuous exposure to unfiltered air we observed pronounced histologic evidence for both perivascular and peribronchial inflammation in the lungs, increased tissue and systemic oxidative stress, dyslipidemia, and an enhanced proinflammatory status of epididymal fat. Results suggest that TLR2/4-dependent inflammatory activation and lipid oxidation in the lung can spill over systemically, leading to metabolic dysfunction and weight gain.—Wei, Y., Zhang, J., Li, Z., Gow, A., Chung, K. F., Hu, M., Sun, Z., Zeng, L., Zhu, T., Jia, G., Li, X., Duarte, M., Tang, X.

Specific autoantigens in experimental autoimmunity-associated atherosclerosis [Research]
Higher cardiovascular morbidity in patients with a wide range of autoimmune diseases highlights the importance of autoimmunity in promoting atherosclerosis. Our purpose was to investigate the mechanisms of accelerated atherosclerosis and identified vascular autoantigens targeted by autoimmunity. We created a mouse model of autoimmunity-associated atherosclerosis by transplanting bone marrow (BM) from FcRIIB knockout (FcRIIB–/–) mice into LDL receptor knockout (LDLR–/–) mice. We characterized the cellular and molecular mechanisms of atherogenesis and identified specific aortic autoantigens using serologic proteomic studies. En face lesion area analysis showed more aggressive atherosclerosis in autoimmune mice compared with control mice (0.64 ± 0.12 mm2vs. 0.32 ± 0.05 mm2; P < 0.05, respectively). At the cellular level, FcRIIB–/– macrophages showed significant reduction (46–72%) in phagocytic capabilities. Proteomic analysis revealed circulating autoantibodies in autoimmune mice that targeted 25 atherosclerotic lesion proteins, including essential components of adhesion complex, cytoskeleton, and extracellular matrix (ECM), and proteins involved in critical functions and pathways. Microscopic examination of atherosclerotic plaques revealed essential colocalization of autoantibodies with endothelial cells (ECs), their adherence to basement membranes, the internal elastica lamina, and necrotic cores. The new vascular autoimmunosome may be a useful target for diagnostic and immunotherapeutic interventions in autoimmunity-associated diseases that have accelerated atherosclerosis.—Merched, A. J., Daret, D., Li, L., Franzl, N., Sauvage-Merched, M. Specific autoantigens in experimental autoimmunity-associated atherosclerosis.

Substantia nigra hyperechogenicity and Parkinson's disease risk in patients with essential tremor
ABSTRACT
Background
Several studies have reported an increased risk for patients with essential tremor to develop Parkinson's disease. In addition, hyperechogenicity in the area of the substantia nigra has been associated with a markedly increased risk for Parkinson's disease. The objective of this study was to evaluate the validity of substantia nigra hyperechogenicity in patients with essential tremor as a risk marker for Parkinson's disease.
Methods
Transcranial sonography was performed in 70 patients suffering from essential tremor. Fifty-four of these patients were available for follow-up after a mean of 6.16 ± 2.05 years and were assessed for the incidence of new-onset Parkinson's disease.
Results
The relative risk for developing Parkinson's disease in patients with essential tremor who had hyperechogenicity at baseline versus those without this hyperechogenicity was 7.00 (95% confidence interval, 1.62–30.34; sensitivity, 77.8%; specificity, 75.6%).
Conclusions
Substantia nigra hyperechogenicity is also associated with an increased risk for Parkinson's disease in patients with essential tremor. These findings further support the potential role of this echofeature as a risk marker for Parkinson's disease. © 2016 Movement Disorder Society
