BACKGROUND: Artemisia and Humulus pollen are the two most important aeroallergens of autumn allergies in North China. Cross-sectional data in 2001 have shown that allergic rhinitis often preceded or occurred at the same time as asthma in patients with autumn pollinosis in North China. OBJECTIVE: We used this cross-sectional data to investigate the association of serum specific IgE (sIgE) levels to Humulus and/or Artemisia pollen with the onset of asthma in patients with autumn pollen-induced allergic rhinitis...

Same-sex parenthood is controversial subject. In this paper, we provide insights into the attitudes and experiences of self-reported lesbians regarding parenthood or the prospect of becoming a parent in the current Greek social and cultural context. In Greece, lesbians are not allowed access to in vitro fertilisation (IVF), while a solitary ('single') woman is allowed access for medical reasons. Fifty-nine (59) semi-structured in-depth interviews were conducted with women. What emerged from our data was a clear trend for participants to wish to have their own biological children based mostly on the belief that pregnancy would lead to a sense of self-completeness and/or fulfilment...

AIM: Although several risk factors contribute to the development of sarcopenia, whether preclinical atherosclerosis contributes to the risk of sarcopenia is not established. The present cross-sectional study aimed to investigate if there is an association between preclinical atherosclerosis and muscle strength among two ethnic populations. METHODS: Participants included individuals aged ≥40 years and enrolled in the third follow-up examination of the Andhra Pradesh Children and Parents Study, India, and in the baseline assessments of the Nagasaki Islands Study, Japan...

Parental care is thought to be costly, as it consumes time and energy. Such costs might be reduced in animal parents that raise their young on valuable food sources such as dung or carcasses, as parents are able to invest in self-maintenance by feeding from the same resource. However, this might lower the nutritional value for other family members and, as a consequence, food competition might arise. To promote our understanding of the outcome of such competition, we manipulated the necessity of parents to feed from the resource...

BACKGROUND: Autism spectrum disorder (ASD), Attention-deficit/Hyperactivity disorder (ADHD), and other related neurodevelopmental disorders (NDDs) have, in some previous studies, been shown to increase the risk of being sexually victimized. However, no studies have examined whether the association is driven by a general NDD phenotype versus specific diagnoses, nor the etiology of the association. METHOD: Using a genetically informative, prospective design, we examined the association between ASD and ADHD in childhood and coercive sexual victimization up to age 18...

The purposes of this study were to describe primary tooth emergence in an American Indian (AI) population during the first 36 mo of life to compare 1) patterns of emergence between male and female children and 2) tooth emergence between these AI children and other U.S. ethnic groups. Data were derived from a birth cohort of 239 AI children from a Northern Plains tribe participating in a longitudinal study of early childhood caries, with examination data at target ages of 8, 12, 16, 22, 28, and 36 mo of age (±1 mo)...

OBJECTIVE: Pharmacological interventions combined with behavioral treatment have been associated with better outcomes for children with ADHD. Yet, as children age into adolescence and gain autonomy, they may choose not to adhere to taking a prescribed medication. The purpose of the current study was to examine school outcomes among adolescents with ADHD who take medication breaks versus resisting medication with respect to grades and school behaviors. METHOD: We statistically controlled for a variety of variables such as the child's age, sex, the presence of side effects, and parent's relationship with child...

This article reviews and integrates research on gender-related biological, cognitive, and social processes that take place in or between family members, resulting in a newly developed gendered family process (GFP) model. The GFP model serves as a guiding framework for research on gender in the family context, calling for the integration of biological, social, and cognitive factors. Biological factors in the model are prenatal, postnatal, and pubertal androgen levels of children and parents, and genetic effects on parent and child gendered behavior...

BACKGROUND: Dental diseases are among the most frequent diseases globally and tooth loss imposes a substantial burden on peoples' quality of life. Non-experimental evidence suggests that individuals with more children have more missing teeth than individuals with fewer children, but until now there is no causal evidence for or against this. METHODS: Using a Two-Stage Least Squares (2SLS) instrumental variables approach and large-scale cross-sectional data from the Survey of Health, Ageing, and Retirement in Europe (study sample: 34 843 non-institutionalised individuals aged 50+ from 14 European countries and Israel; data were collected in 2013), we investigated the causal relationship between the number of biological children and their parents' number of missing natural teeth...

Background: Although both the mother's and father's alleles are present in the offspring, they may not operate at the same level. These parent-of-origin (PoO) effects have not yet been explored on the X chromosome, which motivated us to develop new methods for detecting such effects. Orofacial clefts (OFCs) exhibit sex-specific differences in prevalence and are examples of traits where a search for various types of effects on the X chromosome might be relevant. Materials and Methods: We upgraded our R-package Haplin to enable genome-wide analyses of PoO effects, as well as power simulations for different statistical models...

The selection of the best dairy heifers is mainly driven by the genetic value of their parents. The phenotype analysis of cows and of the daughters of bulls has been used to identify the best genetic value for decades before being replaced by genomic selection of individuals that are not yet parents. Because it is possible to predict the future value of an individual by its genetic makeup, it becomes feasible to do it as early as the blastocyst stage and to decide which should be transferred or not. Because we know the genotype of an animal at birth, or even before, it is becoming desirable to reproduce this animal as soon as possible to reduce generation interval and improve selection speed...

BACKGROUND: Children with asthma and atopic diseases have an increased risk of depression or anxiety. Each of these diseases have strong genetic and environmental components, therefore it seems likely that there is a shared liability rather than causative risk. OBJECTIVE: To investigate the existence and nature of familial aggregation for the comorbidity of atopic diseases and depression or anxiety. METHODS: Participants came from the Childhood and Adolescent Twin Study in Sweden (CATSS), n= 14197...

A small number of genes may interact to determine sex, but few such examples have been demonstrated in animals, especially through comprehensive mating experiments. The highly invasive apple snail Pomacea canaliculata is gonochoristic and shows a large variation in brood sex ratio, and the involvement of multiple genes has been suggested for this phenomenon. We conducted mating experiments to determine whether their sex determination involves a few or many genes (i.e., oligogenic or polygenic sex determination, respectively)...

Background: We recently reported an encouraging decline in the prevalence of overweight (OW) or obesity (OB) in Canadian children from 31% to 27% with stabilization in OB rates at ~13% using national survey data between 2004 and 2013. Although rates were lower for toddlers, girls and those of European (White) race-ethnicity, secular trends persisted after adjustment. In this follow-up study, we explored the ability of socioeconomic status to explain or modify these relationships using the same data set...

The effects of parental exposure to pharmaceuticals on sexual differentiation in F1 offspring were examined in zebrafish (Danio rerio). Adult zebrafish were exposed to 0 or 10 µg/L of carbamazepine or gemfibrozil for 6 weeks and bred in pairwise crosses to generate 7 distinct lineages. Lineages were formed with both parents from the same treatment group or with only one parent exposed, to delineate between maternal and paternal effects. The F1 offspring from each lineage were reared in clean water and sampled at 45 and 60 days post fertilization (dpf)...

This study investigated how supportive relationships with peers and parents protect children against ongoing victimization, internalizing problems and depression. The longitudinal data set tracked progress of 111 children recruited for the trial of Resilience Triple P, and previously bullied by peers. Informants included children, parents and teachers. Higher levels of facilitative parenting (warm parenting that supports peer relationships) and peer acceptance predicted lower later levels of both depression and victimization over time...

INTRODUCTION: Adverse childhood experiences (ACEs) are traumatic events that occur in a child's life between birth and 18 years. Exposure to one or more ACE has been linked to participation in risky health behaviors and the experience of chronic health conditions in adulthood. The risk for poor outcomes increases as the number of ACEs experienced increases. This research investigates rural-urban differences in exposure to ACEs using a sample from a representative southern US state, South Carolina...
