Background: Depression and problematic substance use represent two of the major social and health problems facing young people internationally. Frequently, these conditions co-occur and this co-occurrence is associated with greater functional impact, poorer treatment outcomes, and increased costs to both society and the individual. Objective: This review aims to identify peer-reviewed published trials of interventions for co-occurring substance use and depression delivered to young people, describe these interventions, and critique the methodological quality of the studies. Method: Eleven electronic databases were searched. The reference lists of relevant review papers were searched manually for additional studies not identified by the electronic database search. Results: Initially, 1,976 studies were identified, of which 22 were classified as trial studies of youth-based treatment interventions for co-occurring substance use and depression. Ten of these studies met criteria for review. The majority (60%) utilized a pharmacotherapy component, but found it to be generally no better than placebo when both groups received adjunct counselling. Methodological quality of studies varied. Conclusions: There is a dearth of trials of interventions for co-occurring depression and substance use disorders in young people. The limited data available is promising regarding the overall effectiveness of a psychological counselling approach. Given the importance of early intervention, and the difficulties faced when engaging youth in treatment, there is a need for further focused effort amongst this group. This may require more innovative techniques in intervention design and implementation. Recent advances in Internet- and mobile phone-based therapies present a potential avenue for further research.

Alcoholic liver disease accounts for significant economic burden with second most common cause for liver transplantation in the US. Although alcohol abstinence is most crucial, morbidity and mortality occur amongst those with continuing alcohol intake and with established end stage liver disease due to lack of specific treatment modalities to manage this disease. Patients with severe acute alcoholic hepatitis, a distinct subset of alcoholic liver disease have a potential for mortality in about 25% within about 1 month despite treatment with available specific agents such as corticosteroids and/or pentoxifylline. Hence, there is clear need for newer and better treatment options to manage these patients. In this article, potential emerging newer targets to manage this disease are discussed including intestinal decontamination, caspase inhibitors, antioxidants, and interlukins. In the background of encouraging emerging data (retrospective data from the UNOS database and data from a case matched prospective French study) on the beneficial effects of liver transplantation amongst patients with alcoholic hepatitis who are non-responders to current medical treatments, this article would also deal controversies surrounding the role and use of liver transplantation in patients with alcoholic hepatitis. Issues such as rule of 6 months of abstinence, ethical issues, and shortage of donor organs will be debated.

Tobacco use, primarily in the form of cigarettes, is the leading cause of preventable morbidity and mortality in the United States (U.S.). The adverse effects of tobacco use began to be recognized in the 1940’s and new hazards of active smoking and secondhand smoke (SHS) exposure from cigarettes continue to be identified to this day. This has led to a sustained and wide-ranging array of highly effective regulatory, public health, and clinical efforts that have been informed by extensive scientific data, resulting in marked decreases in the use of cigarettes. Unfortunately, the dramatic recent decline in cigarette use in the U.S., has been accompanied by an upsurge in adolescent and young adult use of new, non-cigarette tobacco and nicotine-delivery products, commonly referred to as alternative tobacco products (ATPs). Commonly used ATPs include hookah, cigars, smokeless tobacco, and electronic cigarettes. While there have been a number of review articles that focus on adult ATP use, the purpose of this review is to provide an overview of what is, and is not known about emerging ATP use among U.S. adolescents on a national scale; as well as to identify research gaps in knowledge, and discuss future health and policy needs for this growing public health concern. This paper is not meant to systemically review all published survey data, but to present clear depiction of selected ATP usage in youth populations using national survey data.

The Opioid Neonatal Abstinence Syndrome (NAS) is a term used to describe a cluster of signs and symptoms seen in infants experiencing withdrawal from opioid drugs. Despite a substantial literature the relationship between maternal methadone dose, NAS and the method of assessment of NAS symptoms has not been agreed. The following review will address current and historical controversies surrounding these issues and will examine the evidence concerned with the evaluation of neonates exposed to methadone in utero. The key findings are as follows: A variety of NAS scales are used to assess the severity of neonatal withdrawal symptoms including locally adapted validated tools. Inconsistencies in the use of NAS scales have included the timing, duration and frequency of administration; the degree to which observers were trained to reliability; the use of NAS scales designed for term neonates to assess pre-term neonates who may have a qualitatively different expression of abstinence symptoms and; the research setting in which the tool was administered. There is a lack of research investigating the observant bias’ effect upon scoring NAS, the basis for treatment decisions and the influence of concomitant maternal use of non-opioid drugs late in pregnancy. We also discuss the implications of the lack of recognition of NAS symptoms leading to possible under reporting and inappropriate, early neonatal discharge from hospital. In addition, this paper also discusses the merits and problems of conducting research in this area and highlights gaps in our knowledge and areas for further research.

The present study is an analytical review of the methodology used in studies of efficacy of screening instruments to detect harmful use/ alcohol dependence according to the gender in population surveys. Systematic review of bibliography was done, using data from Web of Science, Pubmed and PsycInfo. Population studies were included without date range, in English, Spanish or Portuguese languages, with sample of adults, evaluating psychometric characteristics of any alcohol screening instrument, whereas studies in special population or under treatment as well as prevalence of alcohol consumption were excluded. Thirteen studies were selected to be included in the present review. According to the studies, the instruments that presented a better performance among men were AUDIT and its derivatives (6 studies) and CAGE (2 studies), whereas among women, AUDIT and its derivatives (7 studies), followed by CAGE (3 studies). The increase of consumption and problems related to alcohol use and its implications for public health indicate the need and urgency for adequacy of screening instruments to differences of gender in general population. The population surveys in the area are scarce. Furthermore, the found studies present heterogeneous methodology which makes accurate comparisons difficult.
