Optimizing Advanced Trauma Life Support (ATLS®) to Maximize Readiness.

INTRODUCTION: The Army utilizes Individual Critical Task Lists (ICTLs) to track and ensure competency and deployment readiness of its medical service members. ICTLs are the various skills and procedures that the Army has deemed foundational for each area of concentration (AOC)/military occupational specialty (MOS). While many ICTLs involve the patient care that military medical providers regularly provide, some procedures are not as commonly performed. This, when coupled with lower patient volume at military treatment facilities (MTF), poses a challenge for maintaining skill competency and deployment readiness. Fort Campbell's Blanchfield Army Community Hospital (BACH) has created a holistic and unique solution to meet many of these standardized requirements and support a ready medical force. By optimizing the Advanced Trauma Life Support (ATLS®) course curriculum to facilitate ICTL completion, BACH has increased its ICTL completion rates, ATLS® course exposure, and streamlined training requirements. The purpose of this article is to describe this best practice and suggest its applicability to other MTFs. MATERIALS AND METHODS: By cross-referencing the ATLS® course curriculum and appendices with ICTLs, BACH has augmented ATLS® course certification with the additional completion of 12 ICTLs. This new approach not only increases ICTL completion, but also increases ATLS® curriculum exposure to medical providers, such as Registered Nurses or Nurse Practitioners, who would not typically take ATLS®. RESULTS: Since starting this new approach in April 2021, 73 military medical personnel have completed the ATLS® course at BACH, with 24 different medical specialties represented. A total of 361 ICTLs have been completed with specific ICTL completion counts ranging from 13 to 48. Each ICTL tested was completed 100% of its annual requirement. CONCLUSION: ATLS® is a mandatory joint interoperability standard for military physicians and it is also an Army ICTL for many AOCs/MOSs. Only counting completion of this course as one ICTL is a missed opportunity for the time spent by Army medical providers and limits the exposure of ATLS® to select AOCs/MOSs. This optimized and novel approach has been successful at BACH, suggesting its applicability at other MTFs that serve as ATLS® testing sites.

TICI: a taxon-independent community index for eDNA-based ecological health assessment.

Global biodiversity is declining at an ever-increasing rate. Yet effective policies to mitigate or reverse these declines require ecosystem condition data that are rarely available. Morphology-based bioassessment methods are difficult to scale, limited in scope, suffer prohibitive costs, require skilled taxonomists, and can be applied inconsistently between practitioners. Environmental DNA (eDNA) metabarcoding offers a powerful, reproducible and scalable solution that can survey across the tree-of-life with relatively low cost and minimal expertise for sample collection. However, there remains a need to condense the complex, multidimensional community information into simple, interpretable metrics of ecological health for environmental management purposes. We developed a riverine taxon-independent community index (TICI) that objectively assigns indicator values to amplicon sequence variants (ASVs), and significantly improves the statistical power and utility of eDNA-based bioassessments. The TICI model training step uses the Chessman iterative learning algorithm to assign health indicator scores to a large number of ASVs that are commonly encountered across a wide geographic range. New sites can then be evaluated for ecological health by averaging the indicator value of the ASVs present at the site. We trained a TICI model on an eDNA dataset from 53 well-studied riverine monitoring sites across New Zealand, each sampled with a high level of biological replication (n = 16). Eight short-amplicon metabarcoding assays were used to generate data from a broad taxonomic range, including bacteria, microeukaryotes, fungi, plants, and animals. Site-specific TICI scores were strongly correlated with historical stream condition scores from macroinvertebrate assessments (macroinvertebrate community index or MCI; R2 = 0.82), and TICI variation between sample replicates was minimal (CV = 0.013). Taken together, this demonstrates the potential for taxon-independent eDNA analysis to provide a reliable, robust and low-cost assessment of ecological health that is accessible to environmental managers, decision makers, and the wider community.

Medial Prefrontal Cortex Theta Burst Stimulation Improves Treatment Outcomes in Alcohol Use Disorder: A Double-Blind, Sham-Controlled Neuroimaging Study.

Background: Alcohol use disorder (AUD) is associated with elevated brain response to cues. Recent studies have suggested that theta burst stimulation (TBS) to the medial prefrontal cortex (MPFC) can decrease reactivity to cues in a transdiagnostic manner. The goal of this clinical trial was to evaluate the effect of continuous TBS as a tool to decrease drinking behavior and brain reactivity to alcohol cues among individuals with AUD. Methods: A total of 50 individuals with AUD were recruited from an intensive outpatient treatment program. Using a randomized, double-blind, sham-controlled design, participants received 10 sessions of continuous TBS (left frontal pole, 1 session/10 days, 110% resting motor threshold, 3600 pulse/session, cue provocation before and during session). Brain reactivity to alcohol cues was acquired at four time points: at baseline and after all TBS sessions (1 month, 2 months, and 3 months). Results: Overall, 80% of the participants completed all TBS sessions. Individuals who received real TBS were 2.71 times more likely to remain enrolled in the study after 3 months and 3.09 times more likely to remain sober 3 months after treatment initiation. Real TBS also led to a significantly greater reduction in brain reactivity to alcohol cues, specifically a reduction in MPFC-striatum and MPFC-insula connectivity 2 and 3 months after TBS treatment. Conclusions: Ten days of MPFC TBS is well tolerated, reduces drinking, and decreases brain reactivity to alcohol cues for up to 3 months after treatment initiation. These results pave a critical next step in the path toward developing transcranial magnetic stimulation as an intervention for AUD and disorders associated with elevated cue reactivity.

Building a sustainable Mil-Civ partnership to ensure a ready medical force: A single partnership site's experience.

ABSTRACT: One of the challenges in military medicine is ensuring that the medical force deployed to the theater of combat operations is prepared to perform life, limb, and eyesight saving care at a level of care comparable to our top civilian Level I trauma centers. There is increasingly more evidence demonstrating that the majority of military physicians are not exposed to trauma or combat casualty care-relevant surgical cases on a consistent basis in their daily practice at their garrison military treatment facility (MTF). To prevent this widening skills and experience gap from become more of a reality, the 2017 National Defense Authorization Act called for the expansion of military and civilian (Mil-Civ) medical partnerships, working toward embedding military medical providers and surgical teams in busy civilian trauma centers. Vanderbilt University Medical Center is one of the busiest trauma centers in the country and being in close proximity to the local MTF at Fort Campbell, KY, it is primed to become one of the premier Mil-Civ partnerships. Creating a strategy that builds the partnership in a calculated and stepwise fashion through multiple avenues with centralized leadership has resulted in the early success of the program. However, Vanderbilt University Medical Center is not immune to challenges similar to those at other Mil-Civ partnerships, but only by sharing best practices can we continue to make progress.

A preliminary investigation of the role of intraindividual sleep variability in substance use treatment outcomes.

INTRODUCTION: Poor sleep health is common among individuals in early treatment for substance use disorders (SUDs) and may serve an important role in predicting SUD outcomes. However, sleep parameters have been inconsistently linked with risk of relapse, perhaps because previous research has focused on mean values of sleep parameters (e.g., total sleep time [TST], sleep efficiency [SE], and sleep midpoint [SM]) across multiple nights rather than night-to-night fluctuations (i.e., intraindividual variability [IIV]). The current study assessed sleep across the first week of SUD treatment, with the aim of prospectively examining the relationship between mean and IIV of TST, SE, and SM and treatment completion and relapse within one-month post-treatment. METHODS: Treatment-seeking adults (N = 23, Mage = 40.1, 39% female) wore an actigraph to assess sleep for one week at the beginning of an intensive outpatient program treatment. Electronic medical record and follow-up interviews were utilized to determine treatment outcomes. RESULTS: Greater IIV in TST was associated with higher odds of relapse (OR = 3.55, p =.028). Greater IIV in SM was associated with lower odds of treatment completion, but only when removing mean SM from the model (OR = 0.75, p =.046). DISCUSSION: Night-to-night variability in actigraphy-measured TST is more strongly associated with SUD treatment outcomes than average sleep patterns across the week. Integrating circadian regulation into treatment efforts to improve SUD treatment outcomes may be warranted. Given the small sample size utilized in the present study, replication of these analyses with a larger sample is warranted.

Modeling of external self-excitation and force generation on magnetic nanoparticles inside vitreous cavity.

The purpose of this manuscript was to design a better method for recovery from rhegmatogenous retinal detachment (RRD) surgery. We attempted to achieve this by designing a helmet that can manipulate intraocular magnetic nanoparticles (MNPs) and create a magnetic tamponade, eliminating the need for postoperative head positioning. A simulated analysis was developed to predict the pattern of magnetic force applied to the magnetic nanoparticles by external magnetic field. No participants were involved in this study. Instead, magnetic flux and force data for three different helmet designs were collected using virtual simulation tools. A prototype helmet was then constructed and magnetic flux and force data were recorded and compared to virtual data. For both virtual and physical scenarios, magnitude and direction of the resulting forces were compared to determine which design created the controlled direction and strongest forces into the back of the eye. Of the three virtual designs, both designs containing a visor had greater force magnitude than magnet alone. Between both designs with visors, the visor with bends resulted in forces more directed at the back of the eye. The physical prototype helmet shared similar measurements to virtual simulation with minimal percent error (Average = 5.47%, Standard deviation = 0.03). Of the three designs, the visor with bends generated stronger forces directed at the back of the eye, which is most appropriate for creating a tamponade on the retina. We believe that this design has shown promising capability for manipulating intraocular MNPs for the purpose of creating a tamponade for RRD.

Sleep and substance use disorder treatment: A preliminary study of subjective and objective assessment of sleep during an intensive outpatient program.

BACKGROUND AND OBJECTIVES: Characteristics of sleep concerns and their relationship to mental health in heterogeneous substance use disorder (SUD) treatment settings are not well understood. The purpose of this preliminary study was to assess sleep using subjective and objective measures at two time points during SUD treatment and compare sleep changes to changes in mental health measures. METHODS: Treatment-seeking participants completed an assessment battery at the beginning of treatment (Time 1, N = 30) and again upon treatment completion (Time 2, approximately 4 weeks later, N = 22). The majority of participants were White (80%), male (63%), and presenting for alcohol use disorder (60.0%), though almost half reported polysubstance abuse (43%). Comorbidity was common (53%). Sleep and mental health questionnaires with 1 week of actigraphy and sleep diaries were completed at both time points. RESULTS: Most participants met the criteria for a sleep disorder and mean scores on questionnaires showed poor sleep quality, insomnia symptoms, and frequent nightmares, with sleep quality and insomnia improving over time but remaining clinically significant. Nightmares did not improve. Actigraphy indicated poor sleep at both time points. Improvement in insomnia was related to improvement in measures of mental health while changes in actigraphy variables were not related to these measures. DISCUSSION AND CONCLUSIONS: Multiple types of sleep disturbance are prevalent in this population, with nightmares persisting throughout treatment and insomnia symptoms showing a relationship with mental health symptoms. SCIENTIFIC SIGNIFICANCE: This was the first study to longitudinally assess mental health with subjective and objective measures of sleep across multiple types of SUDs in a community SUD treatment setting.

Insomnia severity during early abstinence is related to substance use treatment completion in adults enrolled in an intensive outpatient program.

BACKGROUND: Insomnia and other types of sleep disturbance are highly prevalent during withdrawal across many different types of substance use disorders (SUDs). It is largely unknown how sleep impacts SUD treatment outcomes, including treatment completion. METHODS: A retrospective chart review was conducted to obtain information about sleep disturbance and treatment completion in individuals beginning an intensive outpatient (IOP) SUD treatment program. Demographic data were collected along with number of sessions completed, treatment completion, comorbid psychiatric diagnosis, pertinent lab results, and scores on three self-reported measures of sleep: the Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS). RESULTS: Pertinent information was available for 110 individuals. The majority had clinically significant scores on the ISI and PSQI but not the ESS. ISI, but not PSQI or ESS, was associated with treatment completion, such that those with more insomnia were less likely to complete treatment. CONCLUSION: The high prevalence of insomnia symptoms and poor sleep quality coupled with the relationship between insomnia severity and treatment completion may indicate that more severe symptoms of insomnia are a risk factor for treatment completion and subsequent relapse across many substance types. Applying evidence-based insomnia interventions in SUD treatment programs may have meaningful implications for outcomes.

Smartphone-based mobile thermal imaging technology to assess limb perfusion and tourniquet effectiveness under normal and blackout conditions.

BACKGROUND: Over the past decade, there has been a resurgence of tourniquet use in civilian and military settings. Several key challenges include assessment of limb perfusion and adequacy of tourniquet placement, particularly in the austere or prehospital environments. We investigated the utility of thermal imaging to assess adequacy of tourniquet placement. METHODS: The FLIR ONE smartphone-based thermal imager was utilized. Ten swine underwent tourniquet placement with no associated hemorrhage (n = 5) or with 40% hemorrhage (n = 5). Experiment 1 simulated proper tourniquet application, experiment 2 had one of two tourniquets inadequately tightened, and experiment 3 had one of two tourniquets inadequately tightened while simulating blackout-combat conditions. Static images were taken at multiple time points up to 30 minutes. Thermal images were then presented to blinded evaluators who assessed adequacy of tourniquet placement. RESULTS: The mean core temperature was 38.3 °C in non-hemorrhaged animals versus 38.2 °C in hemorrhaged animals. Hemorrhaged animals were more hypotensive (p = 0.001), anemic (p < 0.001), vasodilated (p = 0.008), and had a lower cardiac output (p = 0.007) compared to non-hemorrhaged animals. The thermal imaging temperature reading decreased significantly after proper tourniquet placement in all animals, with no difference between hemorrhaged and non-hemorrhaged groups at 30 minutes (p = 0.23). Qualitative thermal image analysis showed clearly visible perfusion differences in all animals between baseline, adequate tourniquet, and inadequate tourniquet in both hemorrhaged and non-hemorrhaged groups. Ninety-eight percent of blinded evaluators (n = 62) correctly identified adequate and inadequate tourniquet placement at 5 minutes. Images in blackout conditions showed no adverse impact on thermal measurements or in the ability to accurately characterize perfusion and tourniquet adequacy. CONCLUSIONS: A simple handheld smartphone-based forward looking infrared radiometry device demonstrated a high degree of accuracy, reliability, and ease of use for assessing limb perfusion. Forward looking infrared radiometry also allowed for rapid and reliable identification of adequate tourniquet placement that was not affected by major hemorrhage or blackout conditions.

Resuscitative endovascular balloon occlusion of the aorta for major abdominal venous injury in a porcine hemorrhagic shock model.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a rescue maneuver for unstable patients with noncompressible hemorrhage below the diaphragm. The efficacy of REBOA in the setting a major abdominal venous injury is unknown. Our objective was to examine the use of REBOA in a large animal model of major abdominal venous injury and characterize any impact on the hemodynamics, rate and volume of hemorrhage, and survival. METHODS: Ten swine (35-55 kg) underwent a controlled and validated hemorrhage and ischemia/reperfusion injury protocol to produce shock physiology. Animals were randomly assigned to a control arm (N = 5) or a treatment (REBOA) arm (N = 5). An injury was then created in the common iliac vein. Bleeding was allowed for 60 seconds and the balloon was then inflated in the REBOA arm. Hemodynamics were recorded for 45 minutes or until death. Blood loss was verified post-mortem and bleeding rate calculated. RESULTS: All animals demonstrated shock physiology at the time of randomization. There were no differences between control versus REBOA animals in baseline mean arterial pressure (42 vs. 50), pH (7.29 vs. 7.26), lactate (6.19 vs. 6.26), or INR (1.2 vs. 1.3, all p = NS). REBOA animals demonstrated immediate improvements in mean arterial pressure (50.6 vs. 97.2, p = 0.04). The mean survival time was 4.1 minutes for controls (100% died) versus 40.1 minutes for REBOA (p < 0.01). There was no difference in total blood loss (mean 630 mL for both). The rate of bleeding was significantly lower in the REBOA animals (control 197 mL/min vs. REBOA 14 mL/min, p = 0.02). CONCLUSION: In the setting of an abdominal venous injury, REBOA improved hemodynamics and lengthened survival time. Blood loss was similar between groups but the rate of bleeding was markedly decreased with REBOA. REBOA appears effective for central venous injuries and provides a sustained period of stabilization and window for surgical intervention.

Developing Repetitive Transcranial Magnetic Stimulation (rTMS) as a Treatment Tool for Cocaine Use Disorder: a Series of Six Translational Studies.

PURPOSE OF THE REVIEW: Cocaine dependence is a chronic and relapsing disorder which is particularly resistant to behavioral or pharmacologic treatment, and likely involves multiple dysfunctional frontal-striatal circuits. Through advances in preclinical research in the last decade, we now have an unprecedented understanding of the neural control of drug-taking behavior. In both rodent models and human clinical neuroimaging studies, it is apparent that medial frontal-striatal limbic circuits regulate drug cue-triggered behavior. While non-human preclinical studies can use invasive stimulation techniques to inhibit drug cue-evoked behavior, in human clinical neuroscience, we are pursuing non-invasive theta burst stimulation (TBS) as a novel therapeutic tool to inhibit drug cue-associated behavior. RECENT FINDINGS: Our laboratory and others have spent the last 7 years systematically and empirically developing a non-invasive, neural circuit-based intervention for cocaine use disorder. Utilizing a multimodal approach of functional brain imaging and brain stimulation, we have attempted to design and optimize a repetitive transcranial magnetic stimulation treatment protocol for cocaine use disorder. This manuscript will briefly review the data largely from our own lab that motivated our selection of candidate neural circuits, and then summarize the results of six studies, culminating in the first double-blinded, sham-controlled clinical trial of TMS as a treatment adjuvant for treatment-engaged cocaine users (10 sessions, medial prefrontal cortex, 110% resting motor threshold, continuous theta burst stimulation, 3600 pulses/session). SUMMARY: The intent of this review is to highlight one example of a systematic path for TMS treatment development in patients. This path is not necessarily optimal, exclusive, or appropriate for every neurologic or psychiatric disease. Rather, it is one example of a reasoned, empirically derived pathway which we hope will serve as scaffolding for future investigators seeking to develop TMS treatment protocols.

Effect of the Streptococcus agalactiae Virulence Regulator CovR on the Pathogenesis of Urinary Tract Infection.

Background: Streptococcus agalactiae can cause urinary tract infection (UTI). The role of the S. agalactiae global virulence regulator, CovR, in UTI pathogenesis is unknown. Methods: We used murine and human bladder uroepithelial cell models of UTI and S. agalactiae mutants in covR and related factors, including ß-hemolysin/cytolysin (ß-h/c), surface-anchored adhesin HvgA, and capsule to study the role of CovR in UTI. Results: We found that covR-deficient serotype III S. agalactiae 874391 was significantly attenuated for colonization in mice and adhesion to uroepithelial cells. Mice infected with covR-deficient S. agalactiae produced less proinflammatory cytokines than those infected with wild-type 874391. Acute cytotoxicity in uroepithelial cells triggered by covR-deficient but not wild-type 874391 was associated with significant caspase 3 activation. Mechanistically, covR mutation significantly altered the expression of several genes in S. agalactiae 874391 that encode key virulence factors, including ß-h/c and HvgA, but not capsule. Subsequent mutational analyses revealed that HvgA and capsule, but not the ß-h/c, exerted significant effects on colonization of the murine urinary tract in vivo. Conclusions: S. agalactiae CovR promotes bladder infection and inflammation, as well as adhesion to and viability of uroepithelial cells. The pathogenesis of S. agalactiae UTI is complex, multifactorial, and influenced by virulence effects of CovR, HvgA, and capsule.

Pathogenesis of Streptococcus urinary tract infection depends on bacterial strain and ß-hemolysin/cytolysin that mediates cytotoxicity, cytokine synthesis, inflammation and virulence.

Streptococcus agalactiae can cause urinary tract infection (UTI) including cystitis and asymptomatic bacteriuria (ABU). The early host-pathogen interactions that occur during S. agalactiae UTI and subsequent mechanisms of disease pathogenesis are poorly defined. Here, we define the early interactions between human bladder urothelial cells, monocyte-derived macrophages, and mouse bladder using uropathogenic S. agalactiae (UPSA) 807 and ABU-causing S. agalactiae (ABSA) 834 strains. UPSA 807 adhered, invaded and killed bladder urothelial cells more efficiently compared to ABSA 834 via mechanisms including low-level caspase-3 activation, and cytolysis, according to lactate dehydrogenase release measures and cell viability. Severe UPSA 807-induced cytotoxicity was mediated entirely by the bacterial ß-hemolysin/cytolysin (ß-H/C) because an ß-H/C-deficient UPSA 807 isogenic mutant, UPSA 807ΔcylE, was not cytotoxic in vitro; the mutant was also significantly attenuated for colonization in the bladder in vivo. Analysis of infection-induced cytokines, including IL-8, IL-1ß, IL-6 and TNF-α in vitro and in vivo revealed that cytokine and chemokine responses were dependent on expression of ß-H/C that also elicited severe bladder neutrophilia. Thus, virulence of UPSA 807 encompasses adhesion to, invasion of and killing of bladder cells, pro-inflammatory cytokine/chemokine responses that elicit neutrophil infiltration, and ß-H/C-mediated subversion of innate immune-mediated bacterial clearance from the bladder.

The understanding and experience of mixed emotions in 3-5-year-old children.

The term mixed emotions refers to the presence of two opposite-valence emotions toward a single target. Identifying when children begin to report experiencing and understanding mixed emotions is critical in identifying how skills such as adaptive functioning, coping strategies, environmental understanding, and socioemotional competence emerge. Prior research has shown that children as young as 5 years old can understand and experience mixed emotion, but perhaps appropriately sensitive methodologies can reveal these abilities in younger children. The present study evaluated 57 children between 3 and 5 years old for mixed emotion experience and understanding using an animated video clip in which a character experiences a mixed emotional episode. Ordinal logistic regression was utilized to examine the relation of gender, attention, and understanding of content to experience and understanding of mixed emotion. While only 12% of children reported experiencing mixed emotion while watching the clip, 49% of children-some as young as 3 years old-were able to recognize the mixed emotional experience of the character. Thus, mixed emotion understanding emerges earlier than previously identified and the expression of understanding may develop independently of the ability to report mixed emotion experience. These findings are discussed in relation to cognitive and developmental considerations.

The potential utility of drinking motive questions to screen at-risk drinking in socially anxious patients.

BACKGROUND: Drinking motives are thought to be important mediators of the relationship between social anxiety and alcohol use. This project evaluates whether specific drinking motives accurately reflect alcohol dependence. If so, brief questions about drinking motives could serve as valuable alcohol screening tools with socially anxious patients. METHODS: This investigation was a secondary analysis of an existing data set of 83 subjects with social anxiety disorder and at-risk alcohol use. The relationship between Drinking Motives Questionnaire (DMQ-R-5) subscales and alcohol dependence was evaluated. RESULTS: Coping-Depression was the only subscale that contributed to the unique prediction of a diagnosis of alcohol dependence. Additionally, two items (i.e. "to cheer up when you're in a bad mood" and "to forget painful memories") predicted a diagnosis of alcohol dependence above and beyond their association with each other. CONCLUSIONS: Among patients with social anxiety, two specific questions on the DMQ-R-5 could provide a useful screen for health professionals to predict alcohol dependence. It may be fruitful to specifically target the motives of "to cheer up when you're in a bad mood" and "to forget painful memories" when providing advice during brief interventions.

Treating individuals with social anxiety disorder and at-risk drinking: phasing in a brief alcohol intervention following paroxetine.

Paroxetine alone is not sufficient to decrease alcohol use in socially anxious alcoholics seeking anxiety treatment. We tested the hypothesis that adding a brief-alcohol-intervention (BI) to paroxetine would decrease alcohol use. All subjects (N=83) had a diagnosis of social anxiety disorder, endorsed drinking to cope with anxiety, were NIAAA-defined at-risk drinkers, and were randomized to either paroxetine alone, or paroxetine plus BI. Both groups showed significant improvement in both social anxiety severity (F(5,83)=61.5, p<0.0001) and drinking to cope (e.g. F(4,79)=23, p<0.0001) and these two constructs correlated with each other (B=3.39, SE=0.696, t(71)=4.88, p<0.001). BI was not effective at decreasing alcohol use (e.g. no main effect of group, all p values >0.3). Paroxetine decreased social anxiety severity in the face of heavy drinking and decreasing the anxiety was related to a concurrent decrease in coping related drinking. BI was not effective at decreasing drinking or drinking to cope.

Brief motivational feedback may enhance treatment entry in veterans with comorbid substance use and psychiatric disorders.

BACKGROUND AND OBJECTIVES: There are limited investigations of brief interventions to facilitate treatment entry among individuals with substance use disorders. This study investigated the effectiveness of brief motivational feedback (BMF) for increasing entry into intensive substance abuse treatment in veteran patients. METHODS: Veteran patients (N = 84) with substance use disorders referred for an intake assessment in a substance abuse specialty clinic received either (i) intake assessment plus BMF or (ii) intake assessment as usual (AAU). BMF consisted of brief motivational enhancement feedback pertaining to estimates of alcohol and drug consumption, money spent on drugs and alcohol, and self-reported problems due to substance abuse. Primary outcome was entry in treatment groups in an intensive outpatient program for substance abuse. RESULTS: Patients in BMF and AAU conditions did not significantly differ on indices of treatment entry. However, among patients with comorbid substance dependence and psychiatric disorders, those who received BMF were significantly more likely to enter outpatient treatment groups. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: The addition of motivational feedback to a standard intake assessment enhanced substance abuse treatment entry among veteran patients with comorbid substance use disorders and psychiatric disorders. These preliminary findings extend the use of motivational feedback to facilitate entry into substance abuse treatment among veteran patients with comorbid substance use and psychiatric disorders. Furthermore, they suggest opportunity for more effective patient-treatment matching based on initial motivation and other individual factors such as psychiatric comorbidity.

Severity of anxiety in mental health versus addiction treatment settings when social anxiety and substance abuse are comorbid.

There is increasing interest in the co-occurrence of social anxiety and addiction. Each investigation has a specific vantage point, e.g., the effect social anxiety has in a population with addiction or that of addiction in a population with social anxiety, which could create unique findings. Among comorbid individuals, is social anxiety more severe in people seeking treatment for anxiety, as compared to those seeking treatment for addiction? This report compares social anxiety severity between subjects in two studies--one involving socially anxious individuals (n=38) seeking treatment for addictions; the other (n=41) subjects with social anxiety and an alcohol use disorder, seeking treatment for social anxiety. Baseline severity scores on the Liebowitz Social Anxiety Scale for social anxiety were compared between the groups. No significant differences were found. For both groups, social anxiety was largely in the severe range. The results suggest that clinicians should attend to social anxiety symptom severity in patients with co-occurring social anxiety and addiction, regardless of the condition for which treatment is sought.

Anxiety and alcohol use disorders: comorbidity and treatment considerations.

The co-occurrence of anxiety disorders and alcohol use disorders (AUDs) is relatively common and is associated with a complex clinical presentation. Sound diagnosis and treatment planning requires that clinicians have an integrated understanding of the developmental pathways and course of this comorbidity. Moreover, standard interventions for anxiety disorders or AUDs may need to be modified and combined in targeted ways to accommodate the unique needs of people who have both disorders. Optimal combination of evidence-based treatments should be based on a comparative balance that considers the advantages and disadvantages of sequential, parallel, and integrated approaches.

Alcohol expectancies and social self-efficacy as mediators of differential intervention outcomes for college hazardous drinkers with social anxiety.

The current pilot study examined the roles of two cognitive factors - positive alcohol expectancies of social anxiety reduction and drink refusal self-efficacy relevant to social situations - in mediating greater reduction in alcohol behaviors by the Brief Intervention for Socially Anxious Drinkers (BISAD; n=21) compared to an alcohol psychoeducation (n=20) in a sample of college hazardous drinkers with social anxiety. Mediation analysis results indicated that decreased positive alcohol expectancies and increased drink refusal self-efficacy relevant to social situations accounted for an average of 67% of the variance in treatment outcomes as measured by total quantity of alcohol consumption, heavy drinking days and problems related to alcohol use in the past month. Study results may enhance the understanding of cognitive factors' role in alcohol treatment outcomes, which could in turn improve the efficacy of interventions aimed to reduce hazardous drinking and comorbid social anxiety.
