A recent randomized controlled trial revealed that a multicomponent sepsis transition and recovery (STAR) program delivered through specialized nurse navigators was effective in reducing a composite of 30-day readmission and mortality. Better understanding of patterns of care provided by the STAR program is needed to promote implementation and dissemination of this effective program. This study characterizes individual care activities and distinct "packages" of care delivered by the STAR program.

Many individuals diagnosed with an addictive disorder are members of disadvantaged groups and obtain a high school education or less, yet self-report questionnaires widely used to identify symptoms of addictive disorders do not use best practices to ensure item clarity and comprehension. In the present study, we explore how advanced text-analysis technology can be used to guide the development of a diagnostic questionnaire with an emphasis on maximizing its readability and then test the accuracy of this questionnaire. In Study 1, a self-report questionnaire for symptoms of gambling disorder was created using best practices for item clarity and comprehension.

Participants in randomized control trials (RCTs) should be representative of those most likely to experience the disorder of focus, yet reviews of psychology research studies consistently find certain demographic groups are overrepresented at the price of others being unincluded. The present review aimed to characterize the demographic representation of US-based RCTs for gambling disorder and compare findings to the population of individuals most likely to experience the disorder. Thirteen US-based RCTs comprising a total of 2,343 participants were reviewed.

The absorption spectrum of Ce in a YAG based host grown using the glycothermal method was modified using the addition of Mg-Si pairs. Photoluminescence intensity was dramatically improved by increasing the reaction temperature to 315 °C instead of the conventionally used 300 °C. It was found that Mg acetate and tetraethylorthosilicate (TEOS) are suitable as precursors for the glycothermal process, as EDS elemental mapping showed their homogeneous inclusion in the final product.

Problem gambling screeners are easily accessible and potentially reduce harm for those individuals who engage in risky levels of gambling behavior. However, a recent study found that when frequent gamblers were offered the chance to complete a screener and receive feedback, most chose not to do so. In this paper, secondary analysis was completed on frequent gamblers' open-ended responses to questions regarding reasons for and against completing a problem gambling screener.

A growing literature supports the efficacy of cognitive-behavioral therapies, motivational interventions, and personalized feedback to treat problem and disordered gambling. However, there is currently debate as to how much treatment is necessary. Some studies indicate that attending a greater number of sessions is related to enhanced therapeutic outcomes, while other studies indicate that one session produces equivalent therapeutic outcomes to multiple sessions.

Microsatellites-a type of short tandem repeat (STR)-have been used for decades as putatively neutral markers to study the genetic structure of diverse human populations. However, recent studies have demonstrated that some microsatellites contribute to gene expression, cis heritability, and phenotype. As a corollary, some microsatellites may contribute to differential gene expression and RNA/protein structure stability in distinct human populations.

Negative beliefs about the self, self-blame, guilt, and shame have been consistently linked to emotional problems, such as posttraumatic stress disorder and depression, following trauma exposure. To expand understanding of the potential role of negative self-conscious cognitions and emotions in other forms of posttrauma maladjustments, such as maladaptive behaviors, the current study examined the associations between these cognitions and emotions with dissociation, alcohol use, and avoidant problem-solving. As a secondary goal, the influence of time since trauma exposure was considered given recent data suggesting that some posttraumatic responses require lengthier time following trauma to become salient.
