Aflatoxins are highly toxic fungal metabolites produced by some members of the Aspergillus species. They are low molecular weight lipophilic compounds that are easily absorbed from the gastrointestinal tract. They contaminate most staple foods, including maize, peanuts, peanut butter and sorghum mainly in the tropics where hot and humid conditions promote fungal growth. Absorbed aflatoxins are metabolized by the cytochrome P450 enzyme system in the liver into toxic metabolites. Aflatoxin B (AFB)1 is the most toxic, carcinogenic and mutagenic naturally occurring toxin...

Although it is known that post-traumatic stress symptoms (PTSS) can result from military service, the variance in PTSS unexplained by military service warrants further investigation, and no researchers have investigated South Korean Marines' vulnerability during their 2-year conscripted service as the first line of national defense against threats from North Korea. This study was designed to examine whether resilience mediated the relationship between childhood maltreatment and PTSS in 169 Korean conscripts into the Marine Corps...

Complex behavioral traits, such as alcohol abuse, are caused by an interplay of genetic and environmental factors, producing deleterious functional adaptations in the central nervous system. The long-term behavioral consequences of such changes are of substantial cost to both the individual and society. Substantial progress has been made in the last two decades in understanding elements of brain mechanisms underlying responses to ethanol in animal models and risk factors for alcohol use disorder (AUD) in humans...

HIV testing is the foundation for consolidated HIV treatment and prevention. In this study, we aim to discover the most relevant variables for predicting HIV testing uptake among substance users in substance use disorder treatment programs by applying random forest (RF), a robust multivariate statistical learning method. We also provide a descriptive introduction to this method for those who are unfamiliar with it. We used data from the National Institute on Drug Abuse Clinical Trials Network HIV testing and counseling study (CTN-0032)...

The mechanisms by which childhood socioeconomic status (CSES) affects adult mental health, general health, and well-being are not clear. Moreover, the analytical assumptions employed when assessing mediation in social and psychiatric epidemiology are rarely explained. The aim of this paper was to explain the intermediate confounding assumption, and to quantify differential recall bias in the association between CSES, childhood abuse, and mental health (SCL-10), general health (EQ-5D), and subjective well-being (SWLS)...

BACKGROUND: Anxiety disorders are common mental health disorders with significant impact on the individual as well as burden on the country as a whole. METHODS: A systematic review of databases, reference lists, internet sources, and input from content experts revealed 42 studies that documented the prevalence of anxiety symptoms or disorders. 12 of these studies specifically evaluated anxiety disorders. RESULTS: 4 studies looked at the prevalence of anxiety disorders in the general population, whilst the remainder focused on selected population groups: university students (4 studies); substance abuse (3 studies); and victims of abuse (1 study)...

Adverse early life experiences can potentially increase risk for drug abuse later in life. However, little research has been conducted studying the effects of maternal separation (MS), an experimental model for early life stress, on the rewarding effects of nicotine. Cognitive function may be affected by MS. So, we also investigated whether nicotine administration affect spatial learning and memory in MS adolescent female rats. Rat pups were subjected to daily MS for 15min (MS15) or 180min (MS180) during the first 2 weeks of life or reared under normal animal facility rearing (AFR) conditions...

The aim of the present study was to investigate the evolution of emotion regulation competencies in sexually abused preschoolers. Children's emotion regulation abilities and their emotional lability and negativity were assessed shortly after disclosure of sexual abuse and one year later, and compared to those of non-abused children. A sample of 47 sexually abused (37 girls, 10 boys) and 74 non-abused children (54 girls, 20 boys), aged 3-7 years (M=56.83months; SD=9.55), participated in the study. Parents and daycare educators or teachers completed the Emotion Regulation Checklist (Shields & Cicchetti, 1997) and an adapted version of the History of Victimization Form (Parent & Hébert, 2006)...

BACKGROUND: Substance abuse has been considered as a growing challenge in Georgia that is closely linked with human immune deficiency virus (HIV) and hepatitis C transmission due to unsafe injection and other uncontrolled behaviors. Methadone maintenance therapy is one of the major treatment options for opioid-dependent individuals. It has proven efficacy in decreasing illegal opioid consumption and criminal behavior as well as reducing the level of HIV infection, mortality, HCV infection, and increasing social functioning...

Attachment has been identified as one of various possible mechanisms involved in understanding models of psychosis, but measures that reliably and validly assess attachment styles in psychosis are limited. The aim of this study was to identify attachment patterns in psychosis and examine demographic and clinical correlates across attachment groups. Latent profile analysis on attachment data from 588 participants who met criteria for non-affective psychosis was used to classify people into attachment classes...

Social support by family, friends and significant others is known to buffer the impact of adverse life events on children's well-being and functioning, however little is known about pathways explaining this association. We investigated whether maltreatment-related cognitions mediate the association between social support and posttraumatic stress symptoms (PTSS). Furthermore, age was introduced as moderator. We assessed the history of maltreatment in 200 maltreated children and adolescents (age 8-17 years) using a semi-structured interview...

Drawing on constructs from the trauma literature, the current study evaluated perceptions of safety and controllability of events as potential markers of risk for marijuana use. In addition, we characterized these perceptions in relation to individual level substance abuse risk factors (marijuana expectancies, impulsivity, depression, and anxiety), gender, and race. Data were collected via web survey from college students at two northeastern universities (n=228, 82.0% female). Controllability of events (CE) was rated significantly higher by Blacks than Whites...

Methamphetamine (MA) is one of the most addictive psychostimulant drugs with a high potential for abuse. Our previous studies demonstrated that MA administered to pregnant rats increases pain sensitivity and anxiety in their adult offspring and makes them more sensitive to acute administration of the same drug in adulthood. Because individuals can differ considerably in terms of behaviour and physiology, such as rats that do not belong in some characteristics (e.g. anxiety) to average, can be described as low-responders or high-responders, are then more or less sensitive to pain...

Vaginal discharge and bleeding in children require a through and thoughtful evaluation to diagnose the underlying problem including infections, sexual abuse, and vaginal foreign bodies. We report a 6-year-old girl presenting with bloody vaginal discharge, carefully evaluated for sexual abuse, and finally diagnosed as a vaginal foreign body after vaginoscopy. A rolling hair ball was extracted from the vagina and was diagnosed as trichobezoar pathologically without any endo-ecto-mesodermal residual tissue. The hair ball was genetically detected and diagnosed to belong herself by containing no foreign structure...

BACKGROUND: Snus tobacco characteristics may attract non-tobacco users, including relatively low, but pharmacologically active, doses of nicotine. Lower nicotine doses may limit adverse drug effects while also producing a physiologically active response. OBJECTIVES: This pilot study is the first to profile the acute effects of snus on physiological and subjective assessments in a sample of never-tobacco users. METHODS: Eleven never-tobacco users (five women; <100 uses/lifetime) were recruited from the community via university-approved advertisements...

This paper summarizes The American Journal of Drug and Alcohol Abuse special issue and offers suggestions for future steps. People who use alcohol or other addictive substances are much more likely to use tobacco. Yet, clinicians and scientists have long regarded these addiction categories as separate and unrelated. The resultant benign neglect of tobacco use has had disastrous consequences on patients. This special issue is an important step toward remedying that situation. It has reviewed what is known and what more needs to be discovered regarding the co-occurrence of tobacco use disorder (TUD) and other substance use disorders (SUDs)...
