Alcohol and opiate misuse in adults with cystic fibrosis.

BACKGROUND: International consensus statements on depression and anxiety in adolescents and adults with cystic fibrosis (awCF) recommend assessment for comorbid substance misuse. However, at CF centers, the frequency and impact of substance misuse have not been well characterized, and best practices for prevention, identification, and evidence-based treatment have not been routinely implemented. METHODS: Medical records of 148 awCF over 3 years were reviewed to determine the prevalence of substance misuse (alcohol or opiates) and its relationship with clinical variables and healthcare utilization. Independent sample t test for continuous outcomes and χ2 test for binary outcomes were used to compare groups with and without substance misuse. RESULTS: Substance misuse was documented in 28 (19%) awCF, equally distributed between alcohol (n = 13) and opiates (n = 15). Adults with substance misuse were more likely to be male. The prevalence of diagnosed anxiety and depression did not differ significantly between groups, but those with substance misuse had more severe anxiety (Generalized Anxiety Disorder-7 Item [GAD-7]: 10.0 ± 6.1 vs. 3.3 ± 4.4; p < 0.001) and depressive symptoms (Patient Health Questionnaire-9: 10.4 ± 6.5 vs. 4.0 ± 4.8; p < 0.001). Adults with substance misuse had higher annual rates of missed outpatient CF visits, more frequent "sick" visits, more frequent and longer hospitalizations, and a higher mortality rate. CONCLUSIONS: In awCF, substance misuse is common and associated with adverse indicators of emotional and physical health, including via proxy of service utilization, suggesting that systematic approaches to addressing substance misuse in CF clinics should be considered. Prospective, longitudinal study is warranted to elucidate the complex relationships between depression, anxiety, substance misuse, and health outcomes in individuals with CF.

Feasibility and acceptability of a CF-specific cognitive-behavioral preventive intervention for adults integrated into team-based care.

BACKGROUND: A cystic fibrosis (CF)-specific cognitive-behavioral therapy intervention (CF-CBT) was developed in partnership with the CF community to advance preventive mental health care. Multidisciplinary providers across three centers were trained to deliver CF-CBT for this pilot assessing feasibility/acceptability and preliminary effectiveness of an integrated model of care. METHODS: The 8-session CF-CBT was delivered to 14 adults with mild depression and/or anxiety symptoms in-person and via audio telehealth. Assessment of attrition, engagement, homework completion, treatment satisfaction, and treatment fidelity informed feasibility/acceptability assessment. Mental health outcomes included depression, anxiety, quality of life (Cystic Fibrosis Questionnaire-Revised [CFQ-R), perceived stress and coping. Preliminary effectiveness was evaluated with Cohen's d metric of effect sizes (ES) of pre-post mean change scores. RESULTS: A total of 108 sessions were conducted; 13 adults completed the intervention; 1 discontinued early. Engagement, homework completion, and treatment acceptability were highly rated (mean = 30; SD = 2, range: 27-32 on a 32-point scale). Fidelity scores ranged from 85.7% to 93.6%. Large ES changes reflected improvements in depressive symptoms (-0.83), CFQ-R (Vitality scale: 1.11), and Relaxation Skills (0.93); moderate ES for CFQ-R Role Functioning (0.63), Awareness of Tension (0.62), Coping Confidence (0.70) and CF-specific Coping (0.55); and small ES for anxiety symptoms (-0.22), perceived stress (-0.25), Behavioral Activation (0.29), and several CFQ-R domains, including Emotional Functioning (0.29). Two CFQ-R subscales decreased (Body Image, Eating Concerns). CONCLUSIONS: Results indicated feasibility and acceptability of CF-CBT and its integration into team-based CF care with promising effectiveness, especially for depression. A multicenter randomized controlled trial of CF-CBT will further examine effectiveness of a CF-specific integrated care model.

Neutrophil dysfunction in cystic fibrosis.

BACKGROUND: Excessive neutrophil inflammation is the hallmark of cystic fibrosis (CF) airway disease. Novel technologies for characterizing neutrophil dysfunction may provide insight into the nature of these abnormalities, revealing a greater mechanistic understanding and new avenues for CF therapies that target these mechanisms. METHODS: Blood was collected from individuals with CF in the outpatient clinic, CF individuals hospitalized for a pulmonary exacerbation, and non-CF controls. Using microfluidic assays and advanced imaging technologies, we characterized 1) spontaneous neutrophil migration using microfluidic motility mazes, 2) neutrophil migration to and phagocytosis of Staphylococcal aureus particles in a microfluidic arena, 3) neutrophil swarming on Candida albicans clusters, and 4) Pseudomonas aeruginosa-induced neutrophil transepithelial migration using micro-optical coherence technology (µOCT). RESULTS: Participants included 44 individuals: 16 Outpatient CF, 13 Hospitalized CF, and 15 Non-CF individuals. While no differences were seen with spontaneous migration, CF neutrophils migrated towards S. aureus particles more quickly than non-CF neutrophils (p < 0.05). CF neutrophils, especially Hospitalized CF neutrophils, generated significantly larger aggregates around S. aureus particles over time. Hospitalized CF neutrophils were more likely to have dysfunctional swarming (p < 0.01) and less efficient clearing of C. albicans (p < 0.0001). When comparing trans-epithelial migration towards Pseudomonas aeruginosa epithelial infection, Outpatient CF neutrophils displayed an increase in the magnitude of transmigration and adherence to the epithelium (p < 0.05). CONCLUSIONS: Advanced technologies for characterizing CF neutrophil function reveal significantly altered migratory responses, cell-to-cell clustering, and microbe containment. Future investigations will probe mechanistic basis for abnormal responses in CF to identify potential avenues for novel anti-inflammatory therapeutics.

Student engagement and comfort during a web-based personalized feedback intervention for alcohol and sexual assault.

INTRODUCTION: The purpose of this study was to investigate individual engagement and comfort during a web-based intervention for alcohol and sexual assault risk reduction. METHODS: Participants were 264 college women (aged 18-20) who reported engaging in heavy episodic drinking in the past month. Participants were randomized to either an intervention condition (alcohol, sexual assault risk reduction, or combined) or a control condition (full or minimal assessment). Participants rated their experiences during the procedures following the assessment or receipt of the intervention depending on condition. Survey usage information (e.g., time data, completion of intervention) was automatically recorded. RESULTS: Most participants completed the intervention as intended (in a reasonable amount of time, in private, without consuming substances). Women with a sexual assault history were most comfortable in the sexual assault risk reduction intervention, whereas women who frequently engaged in heavy episodic drinking were least comfortable in the alcohol intervention condition. Self-reported distraction was not impacted by personal relevance of the intervention, but was associated with setting of participation. CONCLUSIONS: Results suggest that most college women completed web-based personalized feedback interventions as designed, despite minimal discomfort.

Is the Use of Protective Behavioral Strategies Associated With College Sexual Assault Victimization? A Prospective Examination.

Sexual assault protective behavioral strategies (PBS) may be negatively associated with sexual assault victimization. However, no studies to date have prospectively examined whether the use of sexual assault PBS is negatively associated with subsequent sexual assault experiences. The current study examined the association between the use of sexual assault PBS and subsequent sexual assault victimization severity. College women who reported engaging in heavy episodic drinking ( n = 77) were assessed online for their use of sexual assault PBS and history of sexual assault victimization. In addition, a 3-month follow-up survey was given assessing sexual assault victimization severity in the past 3 months. The use of sexual assault PBS was negatively associated with sexual assault severity in the 3-month follow-up period. Future research should further examine these PBS to create more college-specific PBS and to determine whether they are useful as risk-reduction strategies.

Differences in Mental Health and Sexual Outcomes Based on Type of Nonconsensual Sexual Penetration.

Little is known based on the stratification and localization of penetration type of rape: oral, vaginal, and/or anal. The current study examined associations between type of rape and mental and sexual health symptoms in 865 community women. All penetration types were positively associated with negative mental and sexual health symptoms. Oral and/or anal rape accounted for additional variance in anxiety, depression, some trauma-related symptoms, and dysfunctional sexual behavior than the association with vaginal rape alone. Findings suggest that penetration type can be an important facet of a rape experience and may be useful to assess in research and clinical settings.

The Use of Drinking and Sexual Assault Protective Behavioral Strategies: Associations With Sexual Victimization and Revictimization Among College Women.

Despite consistent high rates of campus sexual assault, little research has examined effective strategies to decrease sexual assault victimization. Sexual assault and drinking protective behavioral strategies (PBS) may be important means of reducing sexual assault victimization risk on college campuses but need further examination. The current study examined the relationship among sexual assault in childhood, before college, and since college to evaluate the mitigating roles of both sexual assault PBS and drinking PBS on sexual assault victimization. Participants (n = 620) were undergraduate women, 18 to 20 years old. The current study was a cross-sectional online survey assessing participants' sexual assault PBS and sexual assault history. Sexual assault history was positively associated with future sexual assault experiences. Pre-college sexual assault was associated with increased since-college sexual assault and increased drinks per week. Since-college adolescent/adult sexual assault was associated with less use of sexual assault PBS. These findings suggest that PBS may have an important role in sexual assault victimization and future research should examine their usefulness in risk reduction programs for college women.
