treatment from the past 3 years highlights some disappointments (negative results following some of the well-designed clinical trials) and gaps (preliminary studies in need of follow up with robust methodology) but also some promising directions in research of the efficacyof these treatments in a pediatric sample. We offer suggestions for future research including consideration of treatment timing, sequencing, the role of symptom severity in directing treatment selection, the potential value of combined treatments, consideration of how to best account for high placebo response rates, and the incorporation of neurobiological assessments to examine mechanisms and biomarker predictors of treatment response.
Identifying risk factors for STBs during adolescence is essential for suicide prevention. In this review, we employ the Research Domain Criteria (RDoC) framework to synthesize studies on key neurocognitive processes-cognitive control, reward responsiveness/valuation, and negative urgency-relevant to adolescent STBs.
Within subdomains of Cognitive Control, studies of inhibition/suppression and updating/maintenance were mixed, while response selection (i.e., decision-making) deficits were consistently associated with suicide attempts. Fewer studies, by comparison, have probed the Positive Valence Systems. Relative to healthy controls, adolescents with prior STBs may show a blunted neural response to rewards and value rewards less, but findings require replication. Selleck Valaciclovir Finally, negative urgency, which may span subdomains within both Cognitive Control and the Positive Valence Systems, was associated with recent suicide attempts in the only study to directly test this association.
Few studies have examined neuroural activation corresponding to viewing angry faces (relative to a fixation cross) in a sample of depressed youth. They found that, relative to non-attempters, attempters had (a) increased activation in the right anterior gyrus and dorsolateral PFC and (b) reduced functional connectivity between the anterior cingulate gyrus and bilateral insulae. Relatedly, youth with bipolar disorder and a history of suicide attempts showed reduced functional connectivity between the amygdala and the left ventral PFC while viewing emotional (happy, fearful) and neutral faces compared to patient non-attempters [34]. The findings indicate that attempters may have problems regulating and appropriately deploying attention, as well as planning and executing behavioral responses, in emotional contexts.
This review aims to summarize and critically evaluate the current literature on the associations between individual and socio-cultural factors that increase risk for cannabis use disorder (CUD), and policy change.
Epidemiological studies show that areas with permissive legal cannabis climates are associated with greater individual risk factors for CUD. This includes (1) higher rates of edible consumption and vaping, (2) higher delta-9-tetrahydrocannabinol (THC) potency and lower cannabidiol (CBD) levels, and, (3) younger age of initiation of use.
A change in the socio-cultural level, such as shifts in the legalization of cannabis, could interact with individual-level factors in their associations with CUD. There is currently a lack of empirical studies that evaluate this interaction. We propose that future research consider a bioecological framework for CUD to allow for a comprehensive understanding of the effects of legal climate that could inform policy and clinical practice.

This is expected to have a negative impact on the global economy, especially on those countries that depend more on the revenue from sales of crude oil. One of the measures that can be taken to survive this kind of situation in the future is to reduce the unit technical cost for producing a barrel of oil by using locally available materials. This research investigated a local clay sourced from Ropp in Plateau State, Nigeria, by considering its rheological characteristics and economic implications of using it for partial to total substitution of imported bentonite clay for oil and gas drilling operations. The local clay was termed as Ropp bentonite clay (RBC). Various spud mud samples were prepared by dispersing a mixture of imported bentonite clay (IBC) and RBC (0-100%) in 350 ml of water. Certain quantity (0-1 g) of polyacrylamide cellulose was added to the mud samples before rheological and physical properties were determined using the standard API procedure. An economic model was built to determine the cost implications of using any of the mud formulations at different consumption rates. The results show that IBC-RBC blend in the right proportion could save Nigeria 12 to 36% of the cost of bentonite clay used to drill wells in the country.Special emphasis populations in the current context can be defined as groups experiencing health disparities resulting in elevated risk to health, safety, and well-being from drinking alcohol. Individuals from marginalized minority populations often encounter barriers to accessing and receiving effective alcohol treatment due to social inequities and disadvantaged life contexts, which also may adversely affect recovery from alcohol use disorder (AUD). Recovery from AUD often involves the adoption of a stable non-drinking lifestyle (sobriety), increased health and well-being, and increased social connection. Although there has been considerable work on AUD epidemiology among special emphasis populations, little research exists directly examining recovery among racial/ethnic minority populations and/or sexual and gender minority populations. The current narrative review hopes to spark scholarly interest in this critically neglected area. This article opens with a review of special emphasis populations and their alcohol-related risks.
