Radioactive gold nanoparticles coated with BSA: A promising approach for prostate cancer treatment.

Background: Nanotechnology has revolutionized medicine, especially in oncological treatments. Gold nanoparticles (AuNPs) stand out as an innovative alternative due to their biocompatibility, potential for surface modification, and effectiveness in radiotherapeutic techniques. Given that prostate cancer ranks as one of the leading malignancies among men, there's a pressing need to investigate new therapeutic approaches. Methods: AuNPs coated with bovine serum albumin (BSA) were synthesized and their cytotoxicity was assessed against prostate tumor cell lines (LNCaP and PC-3), healthy prostate cells (RWPE-1), and endothelial control cells (HUVEC) using the MTS/PMS assay. For in vivo studies, BALB/C Nude mice were employed to gauge the therapeutic efficacy, biodistribution, and hematological implications post-treatment with BSA-coated AuNPs. Results: The BSA-coated AuNPs exhibited cytotoxic potential against PC-3 and LNCaP lines, while interactions with RWPE-1 and HUVEC remain subjects for further scrutiny. Within animal models, a diverse therapeutic response was observed, with certain instances indicating complete tumor regression. Biodistribution data emphasized the nanoparticles' affinity towards particular organs, and the majority of hematological indicators aligned with normative standards. Conclusions: BSA-coated AuNPs manifest substantial promise as therapeutic tools in treating prostate cancer. The present research not only accentuates the nanoparticles' efficacy but also stresses the imperative of optimization to ascertain both selectivity and safety. Such findings illuminate a promising trajectory for avant-garde therapeutic modalities, holding substantial implications for public health advancements.

Preferences for and barriers to gender affirming surgeries in transgender and non-binary individuals.

Background: The transgender/non-binary community continues to be an underserved population in medicine, and our understanding of their interests, disinterests, and barriers to transition-related healthcare is quite limited, especially among the diverse gender identities within the transgender/non-binary umbrella. Aim: To determine the interests, disinterests and barriers to gender affirming surgeries for transgender men, transgender women and non-binary individuals of any birth-assigned sex. Methods: An anonymous, online survey using REDcap was applied across all 50 states and advertised through social media, healthcare organization websites and flyers. The responses of individuals greater than 18 years of age who identified as transgender or non-binary were analyzed. Results: Compared to the 2015 US Transgender Survey, interest in gender affirming surgeries was higher across all gender identities surveyed and for all procedures, by an average of 38%. Interest overall in gender affirming procedures varied greatly among gender identity groups as well as with age differences. Barriers were found to be a mixture of lack of resources for recovery, financial, and a fear of complications. Discussion: Our results highlight that a desire for these procedures is unique for each individual and should never be assumed for transgender/non-binary patients. In order to better aid this underserved population, the medical community must further work to mitigate the barriers to gender affirming procedures by decreasing cost, investigating ways to increase access to resources for recovery, and improving outcomes for each of the gender affirming surgeries.

Quality of life improvement after chest wall masculinization in female-to-male transgender patients: A prospective study using the BREAST-Q and Body Uneasiness Test.

BACKGROUND: Chest reconstruction in many female-to-male (FTM) transgender individuals is an essential element of treatment for their gender dysphoria. In existing literature, there are very few longitudinal studies utilizing validated survey tools to evaluate patient reported outcomes surrounding this surgery. The purpose of our study is to prospectively evaluate patient reported satisfaction, improvement in body image, and quality of life following FTM chest wall reconstruction. METHODS: Our study was a prospective analysis of FTM patients who underwent chest reconstruction by a single surgeon (C.A.) between April 2015 and June 2016. The patients were surveyed preoperatively and 6 months after surgery utilizing the BREAST-Q breast reduction/mastectomy questionnaire and the Body Uneasiness Test (BUT-A). Analysis was performed on their self-reported demographic information, survey results, and chart review data. RESULTS: Of 87 eligible patients, 42 completed all surveys and could be linked to their chart data. From the BREAST-Q surveys, significant improvements were observed in the domains of breast satisfaction, psychosocial well-being, sexual satisfaction, and physical well-being. From the BUT-A surveys, we observed significant improvement in body image, avoidance, compulsive self-monitoring, and depersonalization. Groups with mental health conditions had poorer initial BUT-A scores and greater degree of improvement after surgery. CONCLUSIONS: As the prevalence of gender affirming surgery increases and as health policies are being developed in this area, the need for evidence-based studies surrounding specific interventions is essential. This study demonstrates significant improvement in a number of quality of life measurements in FTM patients after undergoing chest masculinization surgery.

Female-to-Male Chest Reconstruction: A Review of Technique and Outcomes.

PURPOSE: Female-to-male transgender individuals frequently seek out chest wall masculinization as part of their gender transition and to aid with treating gender dysphoria. Critical evaluation of techniques, complications, and outcomes is important particularly as the surgery becomes more commonly performed. METHODS: A retrospective review was performed of all patients undergoing female-to-male chest wall reconstruction by the senior author from 2008 to 2015. Charts were reviewed to evaluate patient demographics, intraoperative details, and postoperative outcomes. Complications were stratified into major and minor complications based on the need to return to the operating room. Inframammary fold techniques and periareolar techniques cohorts were compared for major complications, minor complications, and need for revision surgeries. RESULTS: Over 8 years, 130 patients were identified. One hundred ten patients underwent inframammary fold techniques, and 20 patients underwent periareolar incisions. Early postoperative complications occurred in 25% of patients. Hematoma was the most common complications, occurring in 14% of patients. Major complications occurred in 8% of patients. Minor complications occurred in 16% of patients, with respiratory problems found to be a significant risk factor. On long-term follow up, 9% of patients had a revision procedure performed. Patients with prior breast surgery were more likely to require revisions (P = 0.009). Of patients requiring revision, 38% had a periareolar incision, compared with only 13% of patients who did not (P = 0.03). For unplanned revisions, there was no difference in periareolar and inframammary techniques. CONCLUSIONS: Our patient cohort demonstrates that female-to-male patients who undergo chest wall contouring through a transverse inframammary fold incision with either composite or standard free nipple grafting have decreased rates of revision surgery and trend toward having lower complication rates as compared with periareolar and limited scar techniques. To best manage expectations, patients undergoing a periareolar or other limited incision technique are counseled regarding an increased risk of hematoma and an increased likelihood of revisions.
