The impact of family systems and social networks on substance use initiation and recovery among women with substance use disorders.

OBJECTIVE: While social networks influence individuals with substance use disorders (SUDs), the mechanisms for such influence are under-explored among women who use drugs. This study triangulates the perspectives of criminal justice professionals, SUD treatment professionals, and women with past and current experiences with substance use to explore these dynamics. METHOD: We conducted semistructured interviews (N = 42) in 2022 with women with current or past opioid use disorder (n = 20), SUD treatment professionals (n = 12), and criminal justice professionals (n = 10) who work with women with opioid use disorder. Interviews centered around participants' backgrounds, perceived barriers and facilitators to medications for opioid use disorder (MOUD) treatment, and gender-specific issues in MOUD treatment. All interviews were audio-recorded, transcribed, and deidentified. We used a four-step qualitative data analysis process to code transcripts. RESULTS: Across these participants' accounts, we identified mechanisms by which women's social networks influenced their opioid use trajectories: intergenerational substance use, family support and strain, intimate partner influence, and peer support and pressure. Overall, the emergent themes in the present study reflect the embedded nature of support within social systems. Women who had access to and engaged with various forms of social support tended to be those who use/used MOUD and self-identified as in recovery. CONCLUSIONS: Combining MOUD treatment with psychosocial interventions allows women to heal from trauma, learn effective coping skills, and receive valuable resources to support recovery. Interventions focusing on family resilience and peer recovery support can disrupt the cycle of addiction and promote MOUD treatment success.

Differences in the molecular profile of endometrial cancers from British White and British South Asian women.

OBJECTIVES: To identify differences in the mutational profile of endometrial tumours between British White (BW) and South Asian (BSA) women. METHODS: We analysed primary tumours from matched cohorts of British White (BW) and British South Asian (BSA) women resident in Leicestershire diagnosed with EC. Next Generation Sequencing was performed to investigate mutational differences in a panel of 10 genes previously identified as being commonly mutated in EC. The presence of somatic Mismatch Repair (MMR) gene deficiencies was determined by immunohistochemistry. RESULTS: In total, 57 tumours (27 BSA and 30 BW) were sequenced. There was no significant difference in the overall mutation frequency of the 10 genes analysed; however, numerous differences were observed between the groups. There was a positive association between PIK3CA and PTEN mutations in the BSA group, with 78% of PIK3CA-mutant tumours harbouring a PTEN mutation, whereas only 11% of PIK3CA wild-type (wt) tumours were PTEN mutant positive (p = 0.0012). In BW women, 90% of ARID1A mutant tumours had co-existent PI3K pathway mutations versus 50% of wild-type (wt) ARID1A patients (p = 0.0485). This trend was not significant in the BSA group (p = 0.66). The age at diagnosis was significantly higher in the BW group with a somatic MMR gene deficiency compared to those with no deficiency (72.8 years versus 59.6 years, p = 0.007), whereas this difference was not seen in the BSA group (64 years versus 60 years, p = 0.37). CONCLUSION: We have identified differences in the mutational profile of primary EC tumours from BW and BSA women. Further research is needed to confirm these findings and to explore their potential implications for early detection, treatment response and prognosis.

Global and mitosis-specific interobserver variation in mitotic count scoring and implications for malignant melanoma staging.

AIMS: Staging is the gold standard for predicting malignant melanoma outcome but changes in its criteria over time indicate ongoing evolution. One notable recent change from the 8th edition of the American Joint Committee on Cancer (AJCC) staging manual was removal of mitotic count. We explore the extent to which this feature is limited by interobserver error in order to find ways to improve its fitness for use should it be revisited in future staging versions. METHODS AND RESULTS: In a cohort of 476 patients with melanoma ≤1.0 mm, a mitotic count of 0 versus 1 was significant for metastasis-free survival, but not melanoma-specific or overall survival. In 10 melanomas that were 0.9-1.0 mm thick, the mitotic count intraclass correlation coefficient for histopathologists was 0.58 (moderate agreement). Uniquely, we also assessed agreement for specific putative mitotic figures, identifying precise reasons why specific mitotic figures qualified for scoring or elimination. A kappa score was 0.54 (moderate agreement). We also gathered data on other staging features. Breslow thickness had an intraclass correlation coefficient of 0.41 (moderate agreement) and there was a systematic difference between histopathologists among cases (P = 0.04). Every case had a range that crossed the AJCC8 0.8-mm pT1a/pT1b staging boundary. Ulceration was only identified in two of the 10 cases. For ulceration, kappa agreement score was 0.31 (fair). CONCLUSION: This study supports the removal of mitotic count from staging, but shows that its scoring is substantially affected by interobserver variation, suggesting that more prescriptive guidelines might have a beneficial impact on its prognostic value.

Insights into stigma management communication theory: Considering stigmatization as interpersonal influence.

The theory of stigma management communication has helped identify and categorize the communication tactics people use to manage stigmatization, yet communication research has provided little insight into predictors of these tactics. To address this gap, we considered stigmatization through the lens of interpersonal influence: as an act in which stigmatizers attempt to persuade their targets to accept categorization and de-individualization into a social group and, further, to accept its marginalized status in the society at large. We used the obstacle hypothesis, a theory of resistance to interpersonal influence, to derive predictors of stigma management strategies. Participants (N=124) facing possible stigmatization due to their genetic risk for a chronic health condition completed an online survey and shared memories of their initial test disclosures. The empirical tests showed that having a stronger sense of meaning in life, more unsafe experiences, and a broader information network predicted resisting stigmatization. Guilt predicted greater use of avoidance strategies (e.g., secrecy and avoiding risky interpersonal settings). We discussed practical implications of bolstering one's sense of meaning in life and argumentation skills and their connections to resilience research.
