Adolescent pregnancy is mostly unintended and an indicator of unmet sexual and reproductive health (SRH) needs. In most African cultures, sociocultural and religious expectations of chastity make unintended adolescent pregnancy a traumatic experience. This study examined the roles of disclosure and social support networks in determining adolescent pregnancy outcomes in Jos, Nigeria. Using a qualitative design, we conducted in-depth interviews with 17 young persons aged 16-24 years, recruited through purposive and snowballing sampling methods. Data were analysed using an inductive approach. Informal social support networks, mainly mothers and close friends, played prominent roles in pregnancy disclosure. The fear of unsafe abortion complications and lack of other options forced most participants into early motherhood. Parenting issues also contributed to unintended adolescent pregnancies. Participants noted that adolescent males had better access to contraceptive devices like condoms. Additionally, the absence of formal opportunities for institutional support through education and youth-friendly SRH services constituted barriers to preventing unintended adolescent pregnancies. Considering the important role family plays, preventing unintended adolescent pregnancies requires empowering parents on SRH communication. A gender-based approach to adolescent-friendly SRH services is recommended. The Nigerian government needs to reconsider how to provide contextually-acceptable comprehensive sexuality education to young people.

Suicidal thoughts and behaviors (STBs) remain a pressing public health problem for transgender and gender diverse (TGD) persons. The goal of this study was to apply social-ecological and minority stress frameworks to identify individual and interpersonal-level TGD-specific STB risk and protective factors. This is a secondary analysis of the 2015 United States Transgender Health Survey, a comprehensive cross-sectional health assessment of a national sample of TGD adults (N = 27,658). Chi-square and Analysis of Variance (ANOVA) were used to identify bivariate correlates of 12-month and lifetime suicidal ideation (SI) and suicide attempt (SA). Logistic regression was employed to identify the strongest STB risk and protective factors across levels. Sexual minority identification, racial minority identification, and having a disability were lifetime STB risk factors. TGD identity, sexual minority identification, racial minority identification (SA only), lower education, lower income, military experience, having a disability, and being uninsured were 12-month STB risk factors. Psychological distress was the most robust STB risk factor. Workplace discrimination, family rejection, healthcare discrimination, and childhood bias-based victimization were lifetime STB risk factors. All forms of discrimination and victimization (with the exception of family rejection for SI) were 12-month STB risk factors. Family and coworker support were protective factors for lifetime SA (but not SI) and all 12-month STBs. Being less out about TGD identity was a protective factor for STBs (except for 12-month SI). Findings support social-ecological and minority stress STB risk frameworks. Recommendations are provided for a comprehensive approach to TGD suicide prevention.

Centrosome amplification has long been established as a hallmark of cancer. More than 80% of invasive breast tumors display this cellular trait. Centrosomal aberrations underlie chromosome instability (CIN) thus corroborating the extensive clonal intratumoral heterogeneity existent within breast lesions that fuels tumor evolution. Sub-clonal heterogeneity drives emergence of aggressive clones with a propensity to migrate and invade, resulting in tumor dissemination and metastases. Thus, centrosome amplification is a critical driver of tumor progression and metastases. Although numerous studies have linked centrosomal overload to tumor aggressiveness, no studies have yet quantified this cell-biological feature to establish a well-defined relationship between the severity and extent of centrosome amplification and tumor aggressiveness. Utilizing an innovative and rationally-guided approach, we have derived an algorithm that allows the precise quantitation of the frequency and severity of both structural and numerical aberrations in supernumerary centrosomes present in clinical samples. Our novel method thus uncovers previously unrecognized differences in the centrosomal profiles of grade-matched breast tumors from African-American (AA) (n=71) and European American (EA) (n=104) women. Our data demonstrate that AA breast tumors exhibit higher numeral, structural and total centrosome amplification scores than grade-matched EA tumors. Interestingly, tumors displaying lymph node and distant metastasis exhibited higher structural amplification than grade-matched non-metastatic tumors. Hence, our novel quantification tool offers valuable information that can potentially predict the risk of AA breast tumors rapidly progressing to metastatic disease and uncovers a hitherto unappreciated organelle-specific disparity marker among racially distinct breast tumors.
