ABSTRACT
Women are at increased risk of trauma exposure and of experiencing prolonged posttraumatic stress. Maternal trauma exposure and associated impairment may adversely impact mother-infant interaction quality, which may in turn be associated with infant temperament difficulties. More research is needed to identify which maternal trauma predictors are most robustly related to infant temperament outcomes. The present study aimed to address this gap by examining maternal sensitivity as a mediator of relations between maternal trauma and infant temperament in a longitudinal study of a rural cohort of mother-infant dyads. Mediation via maternal sensitivity was not supported in any of the primary analyses. Greater maternal trauma exposure was found to predict greater infant regulation behavior, a finding that was in opposition to expected results and which may be explained by protective factors found within the sample. The present sample was skewed toward married, educated women who reported high social support satisfaction and low trauma-associated impairment. The findings elucidate protective factors that may mitigate adverse outcomes for both mothers and infants. Future research models should include additional maternal trauma variables (e.g., recency, type, revictimization/polyvictimization), in utero maternal cortisol exposure, maternal insensitivity/ambiguous response patterns during caregiver tasks, and analysis of the IBQ-R subscales.
ABSTRACT
The current study investigated whether stressful life events and everyday discrimination experiences were associated with using one or more substances in the past 30-days and substance use disorder (SUD) among adults experiencing homelessness. We obtained survey data from adults (N = 501) seeking services at a day shelter. Participants self-reported whether they used cigarettes, other tobacco products, cannabis, alcohol, opioids, amphetamine, and cocaine/crack in the past 30-days, and the total number of substances used were also calculated. We measured stressful life events and everyday discrimination using validated scales. We used multivariable logistic and negative binomial regression analyses to evaluate hypothesised associations. Results indicated that reporting a higher number of stressful life events was associated with past 30-days cannabis, tobacco, alcohol, and other substance use, screening positive for a SUD, and using a greater number of substances in the past 30 days. After accounting for stressful life events, everyday discrimination was associated with only past 30-days cannabis use. Overall, we found that reporting stressful life events was related to current substance use and screening positive for a SUD. Findings suggest that life stressors, and discrimination to a lesser extent, were associated with substance use and SUD among adults experiencing homelessness.

Background: Smoking rates are exceptionally high among adults experiencing homelessness (AEH). Research is needed to inform treatment approaches in this population. Methods: Participants (n=404) were adults who accessed an urban day shelter and reported current smoking. Participants completed surveys regarding their sociodemographic characteristics, tobacco and substance use, mental health, motivation to quit smoking (MTQS), and smoking cessation treatment preferences. Participant characteristics were described and compared by MTQS. Results: Participants who reported current smoking (N=404) were primarily male (74.8%); White (41.4%), Black (27.8%), or American Indian/Alaska Native (14.1%) race; and 10.7% Hispanic. Participants reported a mean age of 45.6 (SD=11.2) years, and they smoked an average of 12.6 (SD=9.4) cigarettes per day. Most participants reported moderate or high MTQS (57%) and were interested in receiving free cessation treatment (51%). Participants most frequently selected the following options as among the top 3 treatments that offered the best chance of quitting: Nicotine replacement therapy (25%), money/gift cards for quitting (17%), prescription medications (17%), and switching to e-cigarettes (16%). Craving (55%), stress/mood (40%), habit (39%), and being around other smokers (36%) were frequently identified as the most challenging aspects of quitting. Low MTQS was associated with White race, lack of religious participation, lack of health insurance, lower income, greater cigarettes smoked per day, and higher expired carbon monoxide. Higher MTQS was associated with sleeping unsheltered, cell phone ownership, higher health literacy, more years of smoking, and interest in free treatment. Discussion: Multi-level, multi-component interventions are needed to address tobacco disparities among AEH.
ABSTRACT
The use of nitrocellulose membranes for invisible ink-messaging or marking for orientation purposes has been carried out with diluted alkaline phosphatase, followed by development with nitro blue tetrazolium/5-bromo-4-chloro-3-indolyl phosphate and chemiluminescence detection systems. Here, we show that nitrocellulose membrane can serve as a canvas for art using alkaline phosphatase and NBT/BCIP detection method.
