Toxic metal ions are an important stress factor for a living organism. In this study, accumulation and histopathological changes in foot, mantle and hepatopancreas of great pond snail, Lymnaea stagnalis exposed to different Cadmium (Cd) concentrations in laboratory conditions were investigated. Great pond snails were exposed to sublethal concentrations of 7.92 μg/L, 15.85 μg/L, 31.7 μg/L and 63.4 μg/L Cd. At the end of 7, 14, 21 and 28 days, snail foot, mantle and hepatopancreas were removed to investigate and determine Cd accumulation and histopathological alterations by light microscopy. Cd levels determined in hepatopancreas were higher than those measured from the foot and the mantle of studied specimens. A positive correlation was found between Cd levels in tissues and exposure days. As a result of Cd application, we observed increase in the number of mucosit, pigment and protein cells and desquamation in the epithelium in the foot, atrophy in muscle fibrils, connective tissue cells and increase in the lipid vacuoles in the mantle, increase in the lipid vacuoles and amoebocyte in the hepatopancreas. The severity of the alterations resulting from Cd increased with dose-time dependent.Background People who inject drugs are highly vulnerable to social determinants of health (SDOH) inequities, such as homelessness, food insecurity, lack of social support, and poor access to healthcare. Supervised consumption sites (SCSs) have been developed to reduce harms associated with injection drug use but their social impacts remain largely unknown. This study explored service users' experiences with SCSs and how their service use affected their SDOH. Methods A qualitative descriptive study design was used. Participants were recruited from an SCS in Ottawa, Canada. Data were collected using in-depth interviews (n = 21). Data analysis involved two cycles of coding that were visibly presented in an analytic matrix. Member checking of the findings was then completed using two focus groups (n = 7). Results Five themes were identified with regard to how SCSs impacted the SDOH (1) social connectedness and community, (2) emotional support and stress reduction, (3) safety and security, (4) current shelter statuses and search for housing, and (5) health service access and use. The perceived effects of SCSs in these domains were mostly positive, though the importance of being vigilant and cautious when using the services was also expressed by participants. Conclusions SCSs represent a potential downstream intervention to addressing some of the SDOH inequities experienced by people who inject drugs. In particular, the findings indicate that SCSs can be a bridge to rebuilding service users' connections with the healthcare system and an important service in efforts to prevent unsheltered homelessness.Background Addiction Consult Services care for hospitalized patients with substance use disorders (SUD), who frequently utilize costly medical services. This study evaluates whether an addiction consult is associated with 30-day acute care utilization. Methods This was a retrospective cohort study of 3905 inpatients with SUD. Acute care utilization was defined as any emergency department visit or re-hospitalization within 30 days of discharge. Inverse probability of treatment weighted generalized estimating equations logistic regression models were used to evaluate the relationship between receipt of an addiction consult and 30-day acute care utilization. Exploratory subgroup analyses were performed to describe whether this association differed by type of SUD and discharge on medication for addiction treatment. Results The 30-day acute care utilization rate was 39.5 % among patients with a consult and 36.0 % among those without. Addiction consults were not significantly associated with care utilization (Adjusted Odds Ratio 1.02; 0.82, 1.28). No significant differences were detected in subgroup analyses; however, the decreased odds among patients with OUD given medication was clinically notable (AOR 0.69; 0.47, 1.02). Discussion Repeat acute care utilization is common among hospitalized patients with SUD, particularly those seen by the addiction consult services. While this study did not detect a significant association between addiction consults and 30-day acute care utilization, this relationship merits further evaluation using prospective studies, controlling for key confounders and with a focus on the impact of medications for opioid use disorder.Background Amphetamines are a first-line treatment for ADHD and have shown promise for the treatment of cocaine use disorder (CUD), both alone and with comorbid ADHD. Impulsiveness is a key aspect of both ADHD and substance use disorders. We sought to understand the role of baseline impulsiveness in the treatment of comorbid CUD and ADHD. Pifithrin-α manufacturer Methods In a post hoc analysis (N = 76) of a 14-week, double-blind, randomized, placebo-controlled trial of mixed amphetamine salts-extended release (MAS-ER) for comorbid ADHD and CUD, we examined the relationship between treatment response and participants' baseline Barratt Impulsiveness Scale (BIS-11) score by comparing those with scores below versus above the median. In the original trial, participants received daily 60 mg MAS-ER, 80 mg MAS-ER, or placebo, in conjunction with cognitive behavioral therapy. Results The odds of a cocaine-abstinent week over time were significantly greater in the high BIS group compared to the low BIS group, both when missing data was treated as missing (p = .0155; OR = 1.23, 95% CI 1.13, 1.35 versus OR = 1.04, 95% CI 0.95, 1.15) and when missing data was treated as cocaine-positive (p = .003; OR = 1.15, 95% CI 1.06, 1.24 versus OR = 0.96, 95% CI 0.88, 1.05). Conclusions The results show an association between higher within-group trait impulsiveness, as measured by the BIS-11, and response to MAS-ER for CUD in a cohort with comorbid ADHD. This result further demonstrates that impulsiveness is an important factor when considering treatment options for patients with CUD and that higher baseline impulsiveness may predict response to treatment with psychostimulants for CUD.
