Introduction: To analyze the effectiveness and suitability of pupillometer use in military and occupational medicine, specifically when pupil size is measured as part of medical surveillance. Pupil size is the most sensitive physical exam finding in vapor exposure to substances that inhibit acetylcholinesterase, such as nerve agent (chemical warfare) and organophosphates (used in agriculture). Pupillometer use permits real-time, accurate pupil measurements, which are of significant value in occupational setting where exposure to organophosphates is suspected and in dynamic military settings where it may be unclear if service members were exposed to nerve agent or not...

Children who enter the child protection system often have complex family problems and have experienced early adverse experiences. Using latent class analysis, this study aimed to identify family classes of child protection cases in Singapore, to ascertain the prevalence of these family classes, and to test the association of family class membership to subsequent recurrence of harm. A sample of 440 cases who entered the Child Protective Service in Singapore was analyzed based on eight familial factors on the household and caregiver levels...

Child welfare involvement has been linked to child behavioral health issues, including increased likelihood of internalizing mental health problems such as depression and anxiety, and externalizing behavioral problems such as oppositional behaviors and substance use problems. One predictor of child behavioral health is caregiver mental health. Although, there remains a specific gap associated with identification of factors among caregivers that are associated with longitudinal child behavioral health trajectories...

Substance-related and behavioral addictions are extremely prevalent and represent a major public health concern. In the ongoing attempt to understand the addictive personality, contradictory results have arisen from studies that have explored personality traits in different addiction populations. The diversity across addiction types suggests that some of these inconsistencies stem from distinct personalities underlying each addiction. The present study compares the personality profiles of several addictions, representing both substance (drugs and alcohol) and behavioral (gambling and sex) subtypes...

Gas chromatography (GC) hyphenated with nitrogen chemiluminescence detection (NCD) and quadrupole time-of-flight mass spectrometry (QTOFMS) was applied for the first time to the quantitative analysis of new psychoactive substances (NPS) in urine, based on the N-equimolar response of NCD. A method was developed and validated to estimate the concentrations of three metabolites of the common stimulant NPS α-pyrrolidinovalerophenone (α-PVP) in spiked urine samples, simulating an analysis having no authentic reference standards for the metabolites and using the parent drug instead for quantitative calibration...

Contemporary research in the drugs field has demonstrated a number of gender differences in patterns and experiences of substance use, and the design and provision of gender-responsive interventions has been identified as an important policy issue. Consequently, whether and how domestic drug policies attend to women and gender issues is an important question for investigation. This article presents a policy audit and critical analysis of Australian national and state and territory policy documents. It identifies and discusses two key styles of problematisation of women's drug use in policy: 1) drug use and its effect on women's reproductive role (including a focus on pregnant women and women who are mothers), and 2) drug use and its relationship to women's vulnerability to harm (including violent and sexual victimisation, trauma, and mental health issues)...

BACKGROUND: Heavy drinkers are at high risk for suicide attempt and suicide. Multiple factors, when examined in isolation, have been implicated in the risk of suicide attempt in this population. In this report, we present a comprehensive model of the 3-year risk of suicide attempt in heavy drinkers using a longitudinal nationally representative study, the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; wave 1, 2001-2002; wave 2, 2004-2005). METHODS: We used structural equation modeling to simultaneously examine effects of four broad groups of clinical factors previously identified as potential predictors of attempted suicides: 1) alcohol use disorder severity, 2) severity of comorbidity, 3) sociodemographic characteristics and 4) help-seeking for alcohol problems...

INTRODUCTION: Dispositional mindfulness can be described as the mental ability to pay attention to the present moment, non-judgmentally. There is evidence of inverse relation between dispositional mindfulness and insomnia and substance use, but as of yet, no studies evaluating the specific association between dispositional mindfulness and the components of hypnotic use disorder. OBJECTIVE: To evaluate the association between dispositional mindfulness and the components of dependence among female chronic hypnotic users...

The Fusarium fungi produce toxic substances called mycotoxins, which can cause disease and harmful effects in grains, livestock, and humans. Deoxynivalenol (DON), also known as vomitoxin, is one of the Fusarium mycotoxins that is known to cause vomiting in livestock. This study shows the occurrence of deoxynivalenol in feedstuffs (compound feed and feed ingredients) between 2009 and 2016 in South Korea. A total of 653 domestic samples were collected at five time points, including 494 compound feed samples and 159 feed ingredient samples...

Photosensitization by drugs is a problem of increasing importance in modern life. This phenomenon occurs when a chemical substance in the skin is exposed to sunlight. Photosensitizing drugs are reported to cause severe skin dermatitis, and indeed, it is generally advised to avoid sunbathing and to apply sunscreen. In this context, the nonsteroidal anti-inflammatory drug (NSAID) diclofenac is a photosensitive drug, especially when administered in topical form. In this work, efforts have been made to design and study an innovative pro-drug/pro-filter system containing diclofenac and the UVA filter avobenzone in order to develop a safer use of this topical drug...

The Internet has played a major role in the distribution of New Psychoactive Substances (NPS), and crypto markets are increasingly used for the anonymous sale of drugs, including NPS. This study explores the availability of individual NPS and vendors on the crypto markets and considers whether crypto markets are a reliable platform for the sale of NPS. Data was collected from 22 crypto markets that were accessed through the hidden web using the Onion Router (Tor). Data collection took place bimonthly from October 2015 to October 2016 as part of the CASSANDRA ( C omputer A ssisted S olutions for S tudying the A vailability a N d D ist R ibution of novel psycho A ctive substances) project...

OBJECTIVE: Knee osteoarthritis (OA) has a significant impact on quality of life (QOL). Although QOL is generally thought to diminish over time, it is unknown if different patient groups demonstrate unique patterns of change in QOL. We sought to identify and characterize QOL trajectories in knee OA. DESIGN: This prospective cohort study included 1013 individuals with symptomatic knee OA from the Osteoarthritis Initiative. We used group-based trajectory modeling to identify distinct temporal patterns of change in the Knee Injury and Osteoarthritis Outcome Score (KOOS) QOL subscale over 8 years...

BACKGROUND: With the introduction of new injectable filler substances and the discontinuation of others, the combination of different types of fillers in a same area is more likely to happen. Naturally, a growing number of concerns regarding the combining of different types of fillers in single area may increase the risk of adverse reactions. Therefore, it has been recommended not to inject a filler in an area previously injected with another type of a filler, especially if that filler is a permanent filler...

Oxidative stress is strongly implicated in the pathogenesis of stroke. Strategies using antioxidants to improve neurological functions after stroke have, thus, gained significant attention. Ocimum basilicum L. is used traditionally to treat CNS disorders. Its antioxidant capacity is well established. Our laboratory has reported protective effects of pre-treatment with O. basilicum in experimental stroke, but its curative (post-treatment) effects in ischemic stroke have not been documented. Hence, the present study was aimed to evaluate the effect of O...

Over time, many pollutants of anthropogenic origin have caused the contamination of aquatic ecosystems. Among several characteristics, these compounds can reach the trophic chain, causing deleterious interactions with the biota. Pharmaceutical substances can be included in this scenario as emerging contaminants that reach the aquatic environment because of direct human and veterinary usage, and release by industrial effluents, as well as through domestic dumping of surplus drugs. The effects of these compounds on exposed organisms have been studied since the 1990s, but ecotoxicological data for such chemicals are still scarce especially concerning aquatic organisms from tropical regions...

I have argued that substance ontology cannot be used to determine the moral status of embryos. Patrick Lee, Christopher Tollefsen, and Robert George wrote a Reply to those arguments in this Journal. In that Reply, Lee, Tollefsen, and George defended and clarified their position that their substance ontology arguments prove that the zygote and the adult into which it develops are the same entity that share the same essence. Here, I show the following: (A) Even using the substance ontology framework to which Lee, Tollefsen, and George subscribe, we cannot know when in development substance changes cease...

Background: Growing evidence indicates that if disruptive behavior is left unidentified and untreated, a significant proportion of these problems will persist and may develop into problems linked with delinquency, substance abuse, and violence. Research is needed to develop valid and reliable measures of disruptive behavior to assist recognition and impact of treatments on disruptive behavior. The aim of this study was to develop and evaluate the psychometric properties of a scale for disruptive behavior in adolescents...

Background: New technologies can profoundly change the way we understand psychiatric pathologies and addictive disorders. New concepts are emerging with the development of more accurate means of collecting live data, computerized questionnaires, and the use of passive data. Digital phenotyping , a paradigmatic example, refers to the use of computerized measurement tools to capture the characteristics of different psychiatric disorders. Similarly, machine learning-a form of artificial intelligence-can improve the classification of patients based on patterns that clinicians have not always considered in the past...

Cavum septum pellucidum (CSP) is a neuroanatomical variant of the septum pellucidum that is considered a marker for disrupted brain development. Several small sample studies have reported CSP to be related to disruptive behavior, persistent antisocial traits, and even psychopathy. However, no large-scale samples have comprehensively examined the relationship between CSP, psychopathic traits, and antisocial behavior in forensic samples. Here we test hypotheses about the presence of CSP and its relationship to psychopathic traits in incarcerated males (N=1432)...
