Genetic And Environmental Factors

The prevalence of allergic diseases is regarded as one of the key challenges in health worldwide. Although the precise mechanisms underlying this rapid increase in prevalence are unknown, emerging evidence suggests that genetic and environmental factors play a significant role. The immune system, microbiota, viruses, and bacteria have all been linked to the onset of allergy disorders in recent years. Avoiding allergen exposure is the best treatment option; however, steroids, antihistamines, and other symptom-relieving drugs are also used. Allergen bioinformatics encompasses both computational tools/methods and allergen-related data resources for managing, archiving, and analyzing allergological data. This study highlights allergy-promoting mechanisms, algorithms, and concepts in allergen bioinformatics, as well as major areas for future research in the field of allergology.

Pain Experiences

The family has long been acknowledged as an important social context where children learn about and receive support for their pain. When a child is in pain, it is the family who is responsible for the initial pain assessment and seeking appropriate evaluation and care. Families may inadvertently encourage the expression of pain and play a critical role in influencing their children’s ability to cope with pain, both positively and negatively. Having a child in pain can also pose significant personal, familial, and economic strains. Therefore, consideration of the family is absolutely critical in the understanding of factors involved in children’s acute and chronic pain experiences (McGrath, 2008). A concentration of research has continued since the last comprehensive review on the topic was published (Chambers, 2003). This chapter considers relevant theoretical models and summarizes current major research themes regarding the role of the family in both acute and chronic paediatric pain. Two illustrative case examples are provided and key areas for future research are identified.

Traditionally, much research effort has been invested into focusing on disease, understanding pathogenic mechanisms, identifying risk factors, and developing effective treatments. A few recent studies unraveling the basis for absence of disease, including cardiovascular disease, despite existing risk factors, a phenomenon commonly known as resilience, are adding new knowledge and suggesting novel therapeutic approaches. Given the central role of endothelial function in cardiovascular health, we herein provide a number of considerations that warrant future research and considering a paradigm shift toward identifying the molecular underpinnings of endothelial resilience.

Chronic Skin Disease

Atopic dermatitis (AD) is a chronic skin disease caused by genetic and environmental factors. Often it begins in early childhood. It is located at the first step of the process we refer to as atopic march. This feature is a precursor of the development of other allergic diseases such as asthma and allergic rhinitis. Especially in patients with atopy of food and inhalant allergens, the occurrence of other atopic diseases is more common. Although the role of these sensitivities in AD is controversial, it has been determined that some patients may trigger eczematous skin lesions. In this report, the role of allergens in atopic dermatitis are reviewed in the light of current literature.

Purpose: Accumulating evidence has shown that allergic diseases are caused by a complex interaction of genetic and environmental factors, some single nucleotide polymorphisms (SNPs) existing in high-affinity IgE receptor β chain (FcεRIβ) are potential risk factors for allergic diseases. However, the results have been inconsistent and inconclusive due to the limited statistical power in individual study. Thus, we conducted a meta-analysis to systematically evaluate the association between FcεRIβ SNPs and allergic diseases risk. Methods: Eligible studies were collected from PubMed, Embase, Web of Science, Chinese National Knowledge Infrastructure, and WanFang databases. Pooled odd ratios (ORs) and corresponding 95% confidence intervals (95% CIs) were calculated to assess the strength of the relationships between five polymorphisms (E237G, -109 C/T, RsaI_in2, RsaI_ex7, and I181L) and the risk of allergic diseases by using five genetic models. In addition, the stability of our analysis was evaluated by publication bias, sensitivity, and heterogeneity analysis. Results: Overall, a total of 29 case–control studies were included in this meta-analysis. We found that E237G (B vs. A: OR = 1.28, 95% CI = 1.06–1.53, P<0.001, I2 = 63.1%) and -109 C/T (BB vs. AA + AB: OR = 1.58, 95%CI = 1.26–1.98, P<0.001, I2 = 66.4%) were risk factors for allergic diseases. Conclusion: Our meta-analysis suggests that polymorphisms in FcεRIβ may be associated with the development of allergic diseases.

SynopsisA genetic analysis of the co-occurrence of bulimia and major depression (MD) was performed on 1033 female twin pairs obtained from a population based register. Personal interviews were conducted and clinical diagnoses made according to DSM-III-R criteria.Additive genes, but not family environment, are found to play an important aetiological role in both bulimia and MD. The genetic liabilities of the two disorders are correlated 0·456. While unique environmental factors account for around half of the variation in liability to both bulimia and MD, these risk factors appear to be unrelated, i.e., each disorder has its own set of unique environmental risk factors. Thus, the genetic liability of bulimia and MD is neither highly specific nor entirely nonspecific. There is some genetic correlation between the two disorders as well as some genetic and environmental risk factors unique to each disorder. Limitations and directions for future research are discussed.

Genetic And Environmental Factors

Abstract Twin design is an important tool to analyze the role of genetic and environmental factors, and to better understand causal mechanisms in public health research. Twin studies have reliably shown that genetic factors are important not only for physiological traits but also for psychological and health behavioral traits as well as for health-related work incapacity in terms of sick leave and disability pension. As many countries face an aging workforce, it is becoming ever more important to understand the underlying causes of work incapacity across the entire working life. In the past decade, twin data in combination with national register data have been used to deepen our understanding of the role of genetic and environmental influences on the complex processes of sick leave and disability pension. The aim of this workshop is to present and discuss methods and results of studies based on the large Swedish, Finnish and Norwegian twin cohorts. Linear structural equations are intensively utilized in modern methods of twin studies. A variety of models are available to answer different research questions, such as the dynamics behind associations between traits and developmental processes in longitudinal designs - models also applicable in health at work and social security. Further, analyzing twin pairs discordant for an outcome or risk factor (co-twin control) provides a unique possibility to control for familial (genetic and shared environmental) factors, since cases and controls are matched optimally being twins. Findings based on twin cohorts suggest that familial factors are relevant to many risk factors as well as for work incapacity. By controlling for these unobserved confounding factors, the co-twin control design may provide more accurate estimates of risk factors for work incapacity and complement the epidemiological findings of unrelated subjects. Based on population-based twin cohort studies with long follow-up, indications also exist that familial confounding may have different roles in the associations between risk factors and work incapacity. For example, in regard to various disability pension diagnosis groups and depending on study designs (one vs. two time points, longer vs. shorter follow-up etc.). Results from prospective studies on various risk factors, including adolescents’ mental health problems, for future sick leave and disability pension will be presented. Another presentation focuses on the stability and change in genetic and environmental factors influencing work incapacity from age 18 until retirement and the likelihood of causality between educational attainment, lifestyle and work incapacity. Finally, results on adverse outcomes of sick leave due to mental disorders using an open cohort design adjusting for familial factors will be presented. During the time of rapid development in molecular genetics, the twin study design has maintained its importance and will continue to cast light on different aspects of work incapacity. Key messages Twin design offers a unique tool in public health research to examine and control for familial (genetic and shared environmental) factors. Genetic factors seem to play an important role in understanding the complex causes of work incapacity in terms of sick leave and disability pension.

Course Of Depression

AbstractAnxiety and depressive disorders are common mental disorders in general population, imposing tremendous burden on both affected persons and society. Moreover, comorbidity between anxiety and depressive conditions is high, leading to substantial disability and functional impairment. Findings consistently suggest that anxiety disorders are primary to depression in the majority of comorbid cases. Yet, the question of whether anxiety disorders are risk factors for depression, and potentially even causal risk factors for the first onset of depression, remains unresolved. Recent results have shown that anxiety disorders increase the risk for subsequent depression, and also affect the course of depression, resulting in a poorer prognosis. Further, some results suggest a dose–response-relationship in revealing that a higher number of anxiety disorders and more severe impairment associated with anxiety disorders additionally increase the risk for subsequent depression. The goal of this paper is to review recent literature, summarize implications of previous findings, and suggest directions for future research regarding preventive and intervention strategies.

Immunological Mechanisms

The immune system regulates itself to establish an appropriate immune response to potentially harmful pathogens while tolerating harmless environmental antigens and self-antigens. A central role in this balance is played by regulatory T cells (Tregs) through various ways of actions. By means of molecule secretion and cell-cell contact mechanisms, Tregs may have the capacity to modulate effector T cells and suppress the action of proinflammatory cytokines across a broad range of cell types. As a result, abnormal regulatory T cell function has been pointed as a main cause in the development of allergic diseases, a major public health problem in industrialized countries, with a high socioeconomic impact. This prevalence and impact have created an international interest in improving the allergy diagnosis and therapy. Additionally, research has sought to gain a better understanding of the molecular mechanisms underlining this kind of disease, in order to a better management. At this respect, the role of Treg cells is one of the most promising areas of research, mainly because of their potential use as new immunotherapeutical approaches. Therefore, the aim of this review is to update the existing knowledge of the role of Tregs in this pathology deepening in their implication in allergen-specific therapy (AIT).

A Current

The fact that stuttering runs in families has been documented over a long period and has led to speculations and research about the role of a genetic component to this disorder. Although the genetic factor cannot be proved by familial aggregation and twin studies alone, such research has continued to provide support for a relationship between stuttering and genetics. The purposes of this article are to review and critique the research in this area. The article first assesses research methodologies that have been employed in familial studies of stuttering. It proceeds to review and critique incidence, twin, and aggregation studies. In addition, it includes sections on subgroups, genetic models of stuttering, and implications for future research as well as for clinical work. With a focus on improved methodology and recent findings, a current perspective on our knowledge of the genetic component to stuttering is provided. Among other conclusions, the article emphasizes that failure to consider epidemiologic factors has probably biased previous results regarding the genetics of stuttering. New preliminary data also appear to provide evidence that spontaneous recovery and chronicity are influenced by genetic factors. Generally, however, the review of incidence and twin studies, as well as of evidence for the various inheritance models, confirms previous conclusions about the interaction between genetic and environmental factors in stuttering.
