Genetic interactions with stressful environments in depression and addiction.

Stress is the most important proximal precipitant of depression, yet most large genome-wide association studies (GWAS) do not include stress as a variable. Here, we review how gene × environment (G × E) interaction might impede the discovery of genetic factors, discuss two examples of G × E interaction in depression and addiction, studies incorporating high-stress environments, as well as upcoming waves of genome-wide environment interaction studies (GWEIS). We discuss recent studies which have shown that genetic distributions can be affected by social factors such as migrations and socioeconomic background.

New Direct-Acting Antiviral Agents and Immunomodulators for Hepatitis B Virus Infection.

Chronic hepatitis B (CHB) affects over 350 million individuals worldwide and is the most common cause of liver cancer. In the United States, CHB affects at least 2 to 3 million individuals, and current therapies can control the disease but not cure it. There are over 30 new molecules being studied in CHB in preclinical to phase 2 studies, targeting specific parts of the hepatitis B virus (HBV) life cycle and the host immune response.

People living with HIV are receptive to HIV prevention interventions in clinical settings: a qualitative evaluation.

In the United States, HIV prevention services are increasingly being offered in the context of healthcare settings. This includes prioritizing prevention services for people living with HIV (PLWH), otherwise known as "prevention with positives." We conducted sixty in-depth interviews to explore patients' perceptions of clinic-based HIV prevention interventions targeting people living with HIV.

Changing women's health, changing nursing practice.

Women's health is a field of study and health care that is of the highest concern for nurses, both from a professional and personal standpoint. It is imperative that those in nursing practice, education, and research be knowledgeable about, prepared for, able to advocate for, and participate in the transformation of health care policy and practice. The changing health care patterns and changing health care delivery system influencing the future of women's health are discussed.

Are children's early emotions antecedents to risk taking?

Purpose: To explore the processes by which early emotional experiences affect behavior and to investigate the use of basic development characteristics to guide primary care.

Method: A randomized cohort of 74 children from a wide range of socio-economic classes were followed from infancy until 54 months of age. Children were assessed at 2 days, 12, 18 and 54 months by laboratory tests and maternal report.

Parasites and T helper cell development: some insights.

Five years after the initial observations implicating the T helper (Th)-cell dichotomy (Th1/Th2) as the focal point in the immunoregulation of murine infection with Leishmania major, investigation has shifted to the factors that govern the differentiation of a specific immune response from its pre-immune of undifferentiated state. In this article, Steven Reiner focuses on the most recent advances concerning the lineage commitment of mature Th-cell populations, showing how new techniques [such as polymerase chain reaction (PCR) and transgenic mice] have allowed for a more-careful dissection of the early evolution of an immune response.

A gandhian model of health: Looking at Alzheimer's disease.

Mahatma Gandhi was often criticized for mixing religion, politics, economics, and health. However, it was his very insistence on the fundamental interrelationship of all aspects of life that gives his ideas such relevance for today's problems. This paper focuses on his views on health and attempts to develop a Gandhian model of health that has relevance for us today.
