Gallbladder disease in transgender individuals: associations with gender-affirming hormone therapy.

Background: Transgender individuals frequently undergo gender-affirming hormone therapy (GAHT) during their gender transition which plays a vital role in gender identity affirmation. Cholelithiasis, a common condition affecting 10-15% of the US population, has been linked to estrogen therapy in cisgender women. Despite the fact that hormonal profiles achieved after GAHT are not always identical to cisgender individuals, the effects of GAHT on gallbladder disease (GBD) risk have not been evaluated in transgender populations. This research aims to address this gap utilizing a large nationwide database. Methods: The study analyzed medical records data from the TrinetX database from 52,847 trans men and 38,114 trans women. Four cohorts were created: trans women and men either receiving either hormone therapy or no intervention. Descriptive statistics were calculated before matching to estimate disease burden. The groups were then propensity score matched on known risk factors (age, race, BMI, etc.) and rates of GBD were compared. Results: Before matching, trans women on hormone therapy (TWHT) had a significantly higher 10-year GBD probability than those naïve to therapy (TWNI) (4.69% vs 1.88%). For trans men, there was no significant difference in 10-year rates between those on therapy (TMHT) and those not (TMNI) (3.15% vs 3.87%). Cholecystectomy rates were significantly higher for TWHT than TWNI (1.10% vs. 0.57%), but similar between TMHT and TMNI (0.95% vs. 1.10%). After accounting for risk factors, TWHT had increased GBD risk (HR 1.832), while TMHT showed no significant change. Discussion: This study suggests a link between estrogen GAHT and increased GBD risk in transgender women. Notably, testosterone GAHT did not offer protection against GBD in transgender men, contrary to expectations. This study is, to our knowledge, the first to describe the burden of GBD in the transgender population and to investigate the effects of GAHT on GBD risk.

Does every transgender person want gender affirming surgery? A survey of transgender individuals in the Midwestern United States.

Gender-affirming surgery (GAS) is a highly personalized decision for transgender and gender diverse (TGD) individuals. However, the proportion of TGD individuals who desire GAS is unknown. A questionnaire was created after identifying themes surrounding experiences with gender-affirming medical care by community focus groups. Respondents who reported medically transitioning and who had undergone GAS were compared to those without prior GAS. From 88 completed surveys, 18 (20.5%) individuals did not wish to undergo GAS. Of those medically transitioning and desiring GAS, 15.2% (9/59) desired GAS but had not received it yet, with 6.7% (6/9) identifying as non-binary. Individuals who had not had GAS were more likely to earn under $15,000 annually, compared to $25,000-49,000 in the GAS group (p = 0.01). There was no significant difference in educational level (p = 0.32) or insurance status (p = 0.33). Of TGD individuals who desire GAS, out-of-pocket expenses such as hair removal, opaque insurance policies, lack of social support, and access to gender-affirming providers can hinder the transition process. Understanding barriers and rationales for pursuing GAS can provide targets for improving healthcare delivery to this diverse population.

Minimally invasive techniques as adjuncts in low- versus high-lying retained rectal foreign bodies of autoerotic nature in young men: a tailored management algorithm with two contrasting case reports from India.

Retained rectal foreign bodies (RFBs) of an autoerotic nature represent an emerging and rare surgical emergency, posing a sensitive challenge for surgeons. RFBs exhibit a wide range of presentations and require varied management approaches, with the choice of treatment modality differing from case to case. Recently, minimally invasive techniques have been employed for the retrieval of RFBs. In 2021, the World Society of Emergency Surgery and the American Association for the Surgery of Trauma released guidelines on anorectal emergencies, highlighting the usefulness of these techniques as adjunctive tools for both diagnosis and ruling out associated complications. In this report, we describe two noteworthy cases of men who presented to the trauma emergency department with foreign bodies lodged in their rectums. We also highlight the potential role of minimally invasive techniques within a "step-up" approach for the management of retained RFBs.

Future directions in transmasculine genital gender-affirming surgery: tissue substitutes and transplant.

PURPOSE OF REVIEW: The present study reviews contemporary literature focused on transplantation and tissue substitutes for the purposes of masculinizing genital gender affirming surgery. Additional background is provided for both topics to provide a more comprehensive understanding of the modern applications. RECENT FINDINGS: Genitourinary vascularized composite allotransplantation has become a reality in recent years with several cases reported worldwide in cisgender men with promising reports of urinary and sexual function. A natural extension might be to apply these techniques to gender affirming surgery (GAS). Technical barriers include anatomic differences between vasculature supporting penoscrotal and vulvovaginal anatomy as well as size discrepancies between the corporal bodies which complicate the required anastomoses. Whether the smaller caliber of biologic female pelvic vasculature can support erection of a neophallus is another obstacle. Ethically, resource allocation, elective immunosuppression, society response to organ donation and gender identity, as well as the psychosocial safety of the patient given charged public opinion must all be considered.Tissue substitutes have long been used in urologic reconstruction but more recently applied to masculinizing gender affirmation surgery which has traditionally relied on autografting. The focus has been on restoring form and function to the donor site as well as facilitating treatment of urethral stricture and wound complications after phalloplasty. Furthermore, aesthetic applications have also been described, most recently for glans atrophy. SUMMARY: The field of masculinizing gender affirmation surgery represents an exciting frontier for surgeons and patients alike. Given the relative nascency of the specialty and its propensity to draw techniques from various surgical disciplines there exists a unique opportunity for rapid innovation to overcome challenging problems posed by these complex procedures as evidenced by discussions around applying penile transplantation and the use of novel tissue grafting techniques.

The burden of chronic pain in transgender and gender diverse populations: Evidence from a large US clinical database.

BACKGROUND: Chronic pain, affecting approximately 20% of the global population, is the leading cause of disability worldwide. Transgender individuals are disproportionately exposed to chronic pain risk factors compared with the cisgender population. This study compares the incidence of chronic pain between transgender and cisgender individuals and examines the impact of gender affirming hormone therapy, anxiety, and depression on chronic pain. METHODS: The study analysed medical records data of 56,470 transgender men and 41,882 transgender women in the TrinetX database. Six cohorts were created: transgender women either receiving oestrogen or no intervention, transgender men receiving testosterone or no intervention and cohorts of cisgender males and females. Unmatched age-adjusted incidence rates were calculated. Then cohorts were matched on 22 chronic pain-associated covariates and the rate of new chronic pain diagnoses was compared between those receiving hormone therapy and those without. RESULTS: We observed significantly higher rates of chronic pain among transgender individuals compared with cisgender counterparts. Transgender men on testosterone therapy and transgender women on oestrogen therapy exhibited an increased likelihood of chronic pain diagnoses compared with those not receiving hormone therapy. Individuals with anxiety and depression were more likely to be diagnosed with chronic pain. CONCLUSION: This study demonstrates a significant burden of chronic pain in transgender individuals, with an increased risk among those receiving hormone therapy. Our study, the first to assess chronic pain in a large cohort of transgender patients, provides support for a potential association between hormone therapy and risk of chronic pain diagnosis. Further research is required to understand causal mechanisms and to develop improved screening and management of chronic pain in transgender populations. SIGNIFICANCE STATEMENT: Our study, featuring the largest cohort of Transgender and Gender Diverse (TGD) individuals assembled to date, reveals critical disparities in chronic pain among TGD populations, notably those on hormone therapy, compared with the cisgender population. It highlights the urgent need for specialized screening and treatment for this vulnerable population, and research into hormone therapy's impact on pain. These insights aim to foster more effective, personalized healthcare, enhancing the well-being and quality of life for the TGD community.

Endoscopic ultrasound (EUS) elastography-guided fine-needle aspiration cytology (FNAC) versus conventional EUS FNAC for solid pancreatic lesions: A pilot randomized trial.

BACKGROUND: Endoscopic ultrasound guided fine-needle aspiration (EUS FNA) is the first-line modality to diagnose suspected solid pancreatic malignant lesions. Elastography-guided FNA has been shown to improve the diagnostic yield of EUS FNA but prospective studies are limited. The aim of the study was to compare diagnostic accuracy, sensitivity and specificity of conventional and elastography-guided EUS FNA in patients with suspected malignant pancreatic solid masses. METHODS: Patients with suspected malignant solid pancreatic lesions presenting to our institute from July 2021 to January 2023 were recruited and randomized to conventional and elastography-guided EUS FNA using a 22-G EUS FNA needle. Diagnostic accuracy, sensitivity, specificity and positive and negative predictive values were calculated. RESULTS: Total 48 patients were initially screened for inclusion in the study, of which six were excluded and 42 patients underwent randomization. Finally, 20 patients in each group underwent the assigned intervention and were analyzed further. Baseline patient characteristics were similar in conventional FNA and elastography-guided FNA group with median age 52 (range 29-74) years and 51.8 (range 31-72) years, respectively, males being 70% and 75%, respectively. Median size of the lesion was 34 mm (range 14-48 mm) and 37 (range 18 to 50 mm), respectively, for both conventional and elastography arm. The average size of the lesion was 35.7 mm. Overall, the diagnosis of adenocarcinoma was made in 65% of cases. In the remaining cases, diagnoses were inflammatory mass, Castleman's disease, solid pseudopapillary epithelial neoplasm (SPEN), diffuse large B-cell lymphoma (DLBCL), pancreatic gastrointestinal stromal tumor (GIST) and metastasis. Conventional EUS FNA had diagnostic accuracy, sensitivity, specificity and positive and negative predictive values of 90%, 87.5%, 100%, 100% and 62.92%, respectively, and elastography-guided EUS FNA had diagnostic accuracy, sensitivity, specificity and positive and negative predictive values of 85%, 100%, 100% and 54.59%, respectively. No severe adverse events were noted. CONCLUSION: There is no significant difference between conventional and elastography-guided EUS FNA in terms of diagnostic accuracy, sensitivity, specificity and positive and negative predictive values. Both techniques appear safe and effective for characterizing solid pancreatic masses and elastography did not score numerically over the conventional arm.

Complication and Explantation Rates of Penile Prostheses in Transmasculine Patients: A Meta-analysis.

OBJECTIVE: To synthesize current literature on penile prosthesis implantation post-gender affirming phalloplasty to correlate implant types and complication rates. METHODS: A meta-analysis of penile prosthesis in transmasculine patients was initiated in December 2022. Inclusion criteria encompassed randomized clinical trials, cohort studies, and cross-sectional studies reporting on penile prosthesis complications post-gender-affirming phalloplasty. Exclusion criteria were review articles, meta-analyses, studies that exclusively reported on cisgender patients or surgeries other than penile prosthesis implantation. An initial search of 5 databases yielded a total of 1593 articles. Upon screening, 15 full-text articles were eligible for inclusion. Nine studies were included in the analysis. RESULTS: The overall complication rate for the inflatable prosthesis group was 38% (95% CI: 21, 59) and for the malleable prosthesis group was 37% (95% CI: 18, 62). The most probable complications in the inflatable group were infection (14.5%), dysfunction (12.9%), dislocation (5.7%), and leakage (5.4%). The most probable complications in the malleable group were dislocation (14.9%), infection (11.2%), dysfunction (9.1%), and extrusion (7.6%). There was no significant difference in the probability of any complications between the malleable and inflatable prosthesis groups. The best estimate of explantation rates for any reason for the inflatable group was 19% (95% CI: 9, 38) and for the malleable group 13% (95% CI: 4, 33). There was no significant difference in the probability of any reason for explantation between the malleable and inflatable prosthesis groups.

Prevalence of unexpected red blood cell antibodies in pregnant women and follow-up of pregnancy outcome in pregnant women treated with intra-uterine transfusion.

BACKGROUND: For the management of hemolytic disease of the fetus and newborn (HDFN), it is important to detect unexpected red cell antibody in pregnant women. We assessed the prevalence of unexpected red cell antibodies in consecutive pregnant women attending antenatal clinic (ANC). More importantly, cases with unexpected antibody causing severe anemia were followed-up for intervention (Intra-uterine transfusion {IUT}) and outcome of pregnancy (still-birth/live-healthy). AIMS AND OBJECTIVES: The study was conducted with an objective to find the prevalence of unexpected RBC antibodies in pregnant women, their specificity and to do the follow-up for IUT and outcome of pregnancy (still-birth, live-birth) in antibody positive women. MATERIALS AND METHODS: This was a prospective study from January 2021 to May 2022 at two tertiary care centres. All antenatal samples received by the laboratory were screened for unexpected red cell antibody. Whenever antibody screen was positive, antibody identification was performed. Patients, positive for unexpected antibody and anemia were followed up for any transfusion-based intervention and outcome of pregnancy. RESULTS: A total of 539 consecutive samples were worked up and among these, 10 samples (1.85%) were found to be antibody positive. The antibodies identified were Anti-D (n=6), anti-Leb (n=1), anti-M (n=1), anti-C (n=1) and anti-E (n=1).The prevalence of unexpected antibodies in Rh positive and Rh negative pregnant women was 0.83% and 10.9% respectively. Follow-up was done for all 10 cases with unexpected antibody and anemia was monitored by MCA PSV (middle cerebral artery peak systolic velocity).Two women developed severe anemia thus requiring single intrauterine transfusion (at 26 weeks and 28 weeks respectively) each, for correction of anemia. In both these cases, healthy male child was delivered. At 3-month follow-up both children were alive and healthy. CONCLUSION: The study found prevalence of unexpected RBC antibodies in pregnant women as 1.85%. The study also underlined importance of transfusion-based interventions contributing to successful outcome in couple of cases with severe anemia.

PLAstic Surgery Teaching In the Undergraduate Curriculum of Medical Students-United Kingdom (PLASTICS-UK): A UK national collaborative survey of plastic surgery in the undergraduate medical curriculum.

OBJECTIVE: To undertake a United Kingdom national medical student survey investigating undergraduate plastic surgery exposure and specialty perceptions. BACKGROUND: Plastic surgery incorporates all anatomical regions, age groups and tissue types; clinical challenges vary from trauma and burns to congenital defects and cancer and although around 50% of the workload is trauma, it is often misperceived to revolve around cosmetic surgery. METHOD: Following ethical approval, a national survey was conducted across 27 included UK medical schools (31/03/23-07/07/23). Trends were analysed, with comparisons made between surgical and non-surgical aspirants. RESULTS: Data were included from 2513 students; 29.2% had surgical career aspirations. Students perceived plastic surgery as challenging, competitive, and impacting quality of life; however, most had no formal teaching (56.3%); merely 6.2% had clinical exposure and 30.4% had an undergraduate plastic surgery placement available. Breast reconstruction was the most frequently correctly identified surgery (91.8%), with head and neck cancer surgery the least (35.9%). Surgical aspirants were less likely to overestimate private practice (p < 0.001) but demonstrated greater self-confidence in plastic surgery understanding (p < 0.001) and their future ability to make plastic surgery referrals (p < 0.001), being more likely to pursue it (p < 0.001). Surgical aspirants were 17.3% more likely to obtain non-curricular plastic surgery experience (p < 0.001), and 5.6% more self-confident dressing basic wounds (p < 0.001). CONCLUSION: A greater need for undergraduate plastic surgery teaching was determined. Significant heterogeneity across medical schools was identified. Formation of a national undergraduate plastic surgery curriculum, led by professional bodies, may tackle disparities among medical schools, improve accessibility and facilitate knowledge acquisition.

Integration of silicon nanostructures for health and energy applications using MACE: a cost-effective process.

Silicon in its nanoscale range offers a versatile scope in biomedical, photovoltaic, and solar cell applications. Due to its compatibility in integration with complex molecules owing to changes in charge density of as-fabricated Silicon Nanostructures (SiNSs) to realize label-free and real-time detection of certain biological and chemical species with certain biomolecules, it can be exploited as an indicator for ultra-sensitive and cost-effective biosensing applications in disease diagnosis. The morphological changes of SiNSs modified receptors (PNA, DNA, etc) have huge future scope in optimized sensitivity (due to conductance variations of SiNSs) of target biomolecules in health care applications. Further, due to the unique optical and electrical properties of SiNSs realized using the chemical etching technique, they can be used as an indicator for photovoltaic and solar cell applications. In this work, emphasis is given on different critical parameters that control the fabrication morphologies of SiNSs using metal-assisted chemical etching technique (MACE) and its corresponding fabrication mechanisms focusing on numerous applications in energy storage and health care domains. The evolution of MACE as a low-cost, easy process control, reproducibility, and convenient fabrication mechanism makes it a highly reliable-process friendly technique employed in photovoltaic, energy storage, and biomedical fields. Analysis of the experimental fabrication to obtain high aspect ratio SiNSs was carried out using iMAGEJ software to understand the role of surface-to-volume ratio in effective bacterial interfacing. Also, the role of silicon nanomaterials has been discussed as effective anti-bacterial surfaces due to the presence of silver investigated in the post-fabrication energy dispersive x-ray spectroscopy analysis using MACE.

A patient with anti-f in India identified by extensive immunohematologic workup.

Anti-f is produced by exposure to the compound antigen ce (f) on red blood cells (RBCs), expressed when both c and e are present on the same protein (cis position). Although anti-f was discovered in 1953, there are few cases reported worldwide because the presence of anti-f is often masked by anti-c or anti-e and is not generally found as a single antibody. In the present case, anti-f was identified by using three-cell screening and 11-cell identification panels. The identification of anti-f was further supported by additional testing, including (1) Rh antigen typing; (2) antibody identification panels (enzyme-treated panel [ficin] and an in-house-constructed Rh panel); (3) look-back and phenotyping of donor RBC units, which were responsible for alloimmunization; and (4) molecular testing of the patient's RBCs.

Deep learning to quantify care manipulation activities in neonatal intensive care units.

Early-life exposure to stress results in significantly increased risk of neurodevelopmental impairments with potential long-term effects into childhood and even adulthood. As a crucial step towards monitoring neonatal stress in neonatal intensive care units (NICUs), our study aims to quantify the duration, frequency, and physiological responses of care manipulation activities, based on bedside videos and physiological signals. Leveraging 289 h of video recordings and physiological data within 330 sessions collected from 27 neonates in 2 NICUs, we develop and evaluate a deep learning method to detect manipulation activities from the video, to estimate their duration and frequency, and to further integrate physiological signals for assessing their responses. With a 13.8% relative error tolerance for activity duration and frequency, our results were statistically equivalent to human annotations. Further, our method proved effective for estimating short-term physiological responses, for detecting activities with marked physiological deviations, and for quantifying the neonatal infant stressor scale scores.

Multidisciplinary management of sexual and gender minorities with bladder cancer.

Bladder cancer, a common urologic malignancy, has poor morbidity and mortality in sexual and gender minority (SGM) individuals, stemming from higher risk, poor access to care and lack of quality cancer care. To begin addressing this disparity, this review offers key considerations for evaluation, diagnosis and treatment of SGM individuals with bladder cancer. In addition to thorough medical and surgical history, initial evaluation should include discussion of patient goals for sexual function and organ preservation, as well as an evaluation of sexual function. Prior gender affirming surgery and patient specific sexual function goals will impact diagnosis and treatment approaches, including surgical and radiation therapy. Throughout care for SGM individuals with bladder cancer, it is critical to acknowledge the systemic discrimination that may be experienced by these individuals and approach conversations with sensitivity and humility and incorporate mental and social support as appropriate.

Legal Outcomes of Litigation After Iatrogenic Genitourinary Trauma.

OBJECTIVE: To evaluate plaintiff and defendant characteristics associated with iatrogenic genitourinary (GU) trauma litigation and outcomes of closed claims. METHODS: LexisNexis was queried in April 2023 using terms related to GU organs and injury, and manually reviewed for iatrogenic cases. Case details including defendant, organ involvement, and legal outcome were obtained. Multinomial regression analysis was performed to identify factors associated with outcome. RESULTS: Four hundred ten cases involving 611 defendants were identified, with the ureter the most commonly affected organ (202/410, 49.3%). Most cases involved adult plaintiffs (380, 92.7%) and resulted in favor of the defense (227, 55.4%). Injuries resulted most frequently from gynecologic surgeries (179, 43.7%). Defendants were most commonly obstetricians/gynecologists (243/611, 39.8%) and urologists (168, 27.5%). Penile (OR 6.3 [95% CI 2.5-16.1]) and urethral (OR 4.8 [2.0-11.7]) injuries were associated with greater odds of a plaintiff verdict relative to ureter injury. A plaintiff verdict was also more likely when defendants were academic hospitals compared to individual practitioners (OR 4.3 [1.9-9.9]). In cases ruling in favor of the plaintiff, indemnity payments were larger when the defendants were comprised of individual practitioners compared to a hospital or medical group (median $549,613 vs $250,000, P <.001). CONCLUSION: Urologists may be involved in medical malpractice lawsuits for iatrogenic injury even when they are uninvolved in the index procedure. Most cases that reach litigation result in defense verdicts regardless of the GU organ injured. Defendant characteristics associated with plaintiff verdicts are more nuanced, and providers should be aware of potential downstream effects of litigation.

Are cisnormative surveys adequate to assess sexual well-being in trans men post-genital gender-affirming surgery?

INTRODUCTION: For transmasculine spectrum individuals, there is a lack of validated surveys to assess sexual well-being (SWB) post-genital gender-affirming surgery. Currently, either providers are designing their own SWB surveys or surveys designed for cisgender men are being used. OBJECTIVE: This study investigated the applicability of SWB surveys validated for cisgender men to transmasculine spectrum individuals post-genital gender-affirming surgery (TMSX). Recognizing the paucity of validated tools for assessing SWB in transmasculine individuals post-genital gender-affirming surgery (TMSX), we evaluated current surveys for their inclusiveness and relevance to this population. METHODS: Our methodology involved analyzing surveys validated in English-speaking North American cisgender men. We conducted a systematic review, yielding 31 surveys, out of which 12 met our inclusion criteria. These were then assessed against the 10 domains of holistic SWB as identified by Özer et al. Each survey was scored based on its reflection of these domains, thus generating an SWB score. Additionally, we performed a thematic analysis to identify areas needing modification for better applicability to TMSX. RESULTS: Our findings indicate an average SWB score of 5.17 out of 10 across the surveys. The surveys predominantly addressed sexual function, with a marked underrepresentation of domains like quality of life, sexuality, and sexual pleasure. This underscores the tendency of these surveys to focus more on the biological mechanisms of sex, rather than on a nuanced biopsychosocial understanding. Thematic analysis revealed significant gaps, such as the irrelevance of questions about erections and ejaculations for TMSX, and the need for greater emphasis on psychosocial factors. CONCLUSION: Given these gaps and the inadequacy of most cisnormative surveys, we recommend the creation of a novel, validated SWB survey specifically for TMSX. This should be developed in collaboration with a multidisciplinary panel and TMSX community advisory board, ensuring a tool that truly reflects the unique SWB needs of this population.
