RESUMO

Transgender and gender-diverse (TGD) people, individuals whose gender identity differs from their sex assigned at birth, face unique challenges in accessing gender-affirming care and often experience disparities in a variety of health outcomes. Clinical research on TGD health is limited by a lack of standardization on how to best identify these individuals. The objective of this retrospective cohort analysis was to accurately identify and describe TGD adults and their use of gender-affirming care from 2003-2023 in a healthcare system in Utah, United States. International Classification of Disease (ICD)-9 and 10 codes and surgical procedure codes, along with sexual orientation and gender identity data were used to develop a dataset of 4,587 TGD adults. During this time frame, 2,985 adults received gender-affirming hormone therapy (GAHT) and/or gender-affirming surgery (GAS) within one healthcare system. There was no significant difference in race or ethnicity between TGD adults who received GAHT and/or GAS compared to TGD adults who did not receive such care. TGD adults who received GAHT and/or GAS were more likely to have commercial insurance coverage, and adults from rural communities were underrepresented. Patients seeking estradiol-based GAHT tended to be older than those seeking testosterone-based GAHT. The first GAS occurred in 2013, and uptake of GAS have doubled since 2018. This study provides a methodology to identify and examine TGD patients in other health systems and offers insights into emerging trends and access to gender-affirming care.

RESUMO

Uterine fibroids (leiomyomas or myomas) are the most common neoplasm of the uterus. Though incompletely understood, fibroid etiology is multifactorial, a combination of genetic alterations and endocrine, autocrine, environmental, and other factors such as race, age, parity, and body mass index. Black women have greater than an 80% incidence of fibroids by age 50, whereas White women have an incidence approaching 70%. Fibroid symptoms are protean, and menorrhagia is most frequent. The societal economic burden of symptomatic fibroids is large, 5.9 to 34.3 billion dollars annually. There are a variety of treatment options for women with symptomatic fibroids ranging from medical therapy to hysterectomy. Myomectomy and uterine fibroid embolization are the most common uterine sparing therapies. Pelvic ultrasound (transabdominal and transvaginal) with Doppler and MRI with and without intravenous contrast are the best imaging modalities for the initial diagnosis of fibroids, the initial treatment of known fibroids, and for surveillance or posttreatment imaging. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer-reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which peer-reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

RESUMO

PURPOSE: Treating uterine fibroids with less invasive therapies such as magnetic resonance-guided focused ultrasound (MRgFUS) is an attractive alternative to surgery. Treatment planning can improve MRgFUS procedures and reduce treatment times, but the tissue properties that currently inform treatment planning tools are not adequate. This study aims to develop an ex vivo uterine fibroid model that can emulate the in vivo environment allowing for characterization of the uterus and fibroid MR, acoustic, and thermal tissue properties while maintaining viability for the necessary postsurgical histopathological assessments. METHODS: Women undergoing a hysterectomy due to fibroid-related symptoms were invited to undergo a preoperative pelvic MRI and to permit postoperative testing of their uterine specimen. Patients that declined or could not be scheduled for a pre-operative MRI were still able to allow post-operative testing of their excised tissue. Following surgical removal of the uterus, nonmorcellated tissues were reperfused with a Krebs-Henseleit buffer solution. An MR-compatible perfusion system was designed to maintain tissue viability inside the MR suite during scanning. MR imaging protocols utilized preoperatively were repeated on whole sample, reperfused ex vivo uterus specimens. Thermal properties including thermal diffusivity and thermal conductivity of the uterus and fibroids were determined using an invasive needle sensor device in 50% of the specimens. Acoustic property measurements (density, speed of sound and attenuation) were obtained for approximately 20% of the tissue samples using both through-transmission and radiation force balance techniques. Differences between fibroid and uterus and in vivo and ex vivo measurements were evaluated with a two-tailed Student t test. RESULTS: Fourteen patients participated in the study and measurements were obtained from 22 unique fibroids. Of the 16 fibroids available for preoperative MRI testing, 69% demonstrated classic hypo-intensity relative to the myometrium, with the remainder presenting with iso- (25%) or hyper-intensity (6%). While thermal diffusivity was not significantly different between fibroid and myometrium tissues (0.217 ± 0.047 and 0.204 ± 0.039 mm2 /s, respectively), the acoustic attenuation in fibroid tissue was significantly higher than myometrium (0.092 ± 0.021 and 0.052 ± 0.023 Np/cm/MHz, respectively). When comparing in vivo with ex vivo MRI T1 and T2 measurements in fibroids and myometrium tissue, the only difference was found in the fibroid T2 property (P < 0.05). Finally, the developed perfusion protocol successfully maintained tissue viability in ex vivo tissues as evaluated through histological analysis. CONCLUSIONS: This study developed an MR-compatible extracorporeal perfusion technique that effectively maintains tissue viability, allowing for the direct measurement of patient-specific MR, thermal, and acoustic property values for both fibroid and myometrium tissues. These measured tissue property values will enable further development and validation of treatment planning models that can be utilized during MRgFUS uterine fibroid treatments.

RESUMO

BACKGROUND: Until recently, no HPV test had been US FDA-approved for SurePath preservative. Clinical performance remains incompletely understood. The clinical performances of the Cobas HPV Test (Cobas) and Hybrid Capture 2 High-Risk HPV DNA Test (HC2) with PreservCyt and SurePath preservatives were compared. METHODS: Cervical cytology samples were collected in both preservatives in random order from women age 21+ (n = 244) referred for colposcopy. Before cytology processing and pelleting, SurePath samples were tested by the Cobas test with and without buffered SDS heat pretreatment. SurePath pellets were tested by the HC2 test and by the Cobas test (with pretreatment). Performance characteristics were calculated in relation to cases of cervical in-traepithelial neoplasia grade 2 or higher (CIN2+) as the clinical target outcome. All HPV-positive samples were also genotyped with the Linear Array test. RESULTS: CIN2+ was detected in 42 patients (17.2%). For both HPV tests, there was a trend towards higher positivity and sensitivity for SurePath compared to PreservCyt preservative. The Cobas test had higher sensitivity than HC2 and the HC2 test had higher specificity than Cobas. Pretreated SurePath samples produced results similar to untreated ones, despite a two-fold dilution during pretreatment [sensitivity %: 95.1 (82.2 - 99.2) vs. 94.3 (79.5 - 99.0); specificity %: 33.0 (26.6 - 40.1) vs. 33.0 (26.4 - 40.3)]. CONCLUSIONS: There was good agreement between the preservatives and HPV tests in detecting HPV and between the Cobas and Linear Array tests for genotyping HR-HPV. These trends were not statistically significant due to the limited number of CIN2+ cases. However, these data may help in evaluations of preservative selection for colposcopy samples. Pre-treatment for Cobas testing eliminated invalid results due to clots. The Cobas test has been FDA-approved for use with heat pretreated SurePath samples.

RESUMO

Over the last 2 decades, the rate of oophorectomy at the time of hysterectomy in the United States has consistently been between 40-50%. A decline in hormone use has been observed since the release of the principal results of the Women's Health Initiative. Oophorectomy appears to be associated with an increased risk of coronary heart disease, as well as deleterious effects on overall mortality, cognitive functioning, and sexual functioning. Estrogen deficiency from surgical menopause is associated with bone mineral density loss and increased fracture risk. While hormone therapy may mitigate these effects, at no age does there appear to be a survival benefit associated with oophorectomy. Reduction of ovarian cancer risk may be accomplished with salpingectomy at the time of hysterectomy.

RESUMO

The urethra, bladder, and ureters are particularly susceptible to injury during gynecologic surgery. When preventive measures fail, prompt recognition and management of injury can avoid long-term sequelae such as fistula formation and loss of renal function. Intraoperative identification should be the primary goal when an injury occurs, although this is not always possible. Postoperative injury recognition requires a high level of suspicion and vigilance. In addition to history and physical examination, appropriate radiologic studies can be useful in localizing injury and planning management strategies. Some injuries may require Foley catheter drainage or ureteral stenting alone, whereas others will require operative intervention with ureteral resection and reanastomosis or reimplantation. Prompt restoration of urinary drainage or diversion will avoid further renal compromise.

RESUMO

Intracorporeal electromechanical morcellation has been available for nearly 2 decades, and has allowed hundreds of thousands of women to undergo hysterectomy and myomectomy in a minimally invasive approach. Despite gains in postoperative pain, complications, quality of life, hospital stay, and return to work, it has recently come under attack. The risk of inadvertent morcellation of a uterine malignancy, and subsequent dissemination of occult cancer, must be balanced by the risks of increased numbers of laparotomies. Power morcellation should be available to appropriate surgical candidates.

RESUMO

Injuries to the urinary tract during laparoscopic hysterectomy are quite rare, but are among the most serious injuries that occur during gynecologic surgery. Injury rates among subtypes of laparoscopic hysterectomy have been found to be similar. The most effective way to avoid urinary tract injury is knowledge of urinary tract anatomy and careful and thoughtful dissection.

RESUMO

This project uses an ex vivo human perfusion model for studying transport in benign, fibrous tumors. The uterine arteries were cannulated to perfuse the organ with a buffer solution containing blood vessel stain and methylene blue to analyze intratumoral transport. Gross examination revealed tissue expansion effects and a visual lack of methylene blue in the fibroids. Some fibroids exhibited regions with partial methylene blue penetration into the tumor environment. Histological analysis comparing representative sections of fibroids and normal myometrium showed a smaller number of vessels with decreased diameters within the fibroid. Imaging of fluorescently stained vessels exposed a stark contrast between fluorescence within the myometrium and relatively little within the fibroid tissues. Imaging at higher magnification revealed that fibroid blood vessels were indeed perfused and stained with the lipophilic membrane dye; however, the vessels were only the size of small capillaries and the blood vessel coverage was only 12% that of the normal myometrium. The majority of sampled fibroids had a strong negative correlation (Pearson's r=-0.68 or beyond) between collagen and methylene blue staining. As methylene blue was able to passively diffuse into fibroid tissue, the true barrier to transport in these fibroids is likely high interstitial fluid pressure, correlating with high collagen content and solid stress observed in the fibroid tissue. Fibroids had an average elevated interstitial fluid pressure of 4mmHg compared to -1mmHg in normal myometrium. Our findings signify relationships between drug distribution in fibroids and between vasculature characteristics, collagen levels, and interstitial fluid pressure. Understanding these barriers to transport can lead to developments in drug delivery for the treatment of uterine fibroids and tumors of similar composition.

RESUMO

STUDY OBJECTIVE: The Fellowship in Minimally Invasive Gynecologic Surgery (FMIGS) is a postresidency fellowship developed with the mission to train the next generation of minimally invasive gynecologic surgeons. The need for surgeons trained in this field has increased, yet there remains a paucity of information regarding the compensation of these specialized surgeons. DESIGN: A survey was sent via e-mail to FMIGS graduates (N = 221) using an online survey tool; it was sent twice more to increase the response rate between July and December 2013. The survey collected information on current and starting salaries and benefits as well as academic rank, location, practice type, and practice breadth. Comparisons were analyzed using multivariable linear regression models (Canadian Task Force Classification II-2). SETTING: E-mail-based survey. PATIENTS: Graduates of the FMIGS. INTERVENTIONS: A single survey sent 3 times. MEASUREMENTS AND MAIN RESULTS: Of 221 graduates surveyed, 164 responded (response rate = 74%). Sixty-one percent of respondents (n = 100) were from academic institutions, and the remainder were from private practice (n = 64). Of all respondents, 27 (16.5%) reported less than 1 year of postfellowship experience and had a median starting salary of $216 399 (range, $106 834-$542 930). Survey respondents were on average 3.3 years (range, 0-14) out of fellowship with a median salary of $238 198 (range, $108 200-$993 765). Academic surgeons (average experience = 3.4 years) earned $208 743 (range, $106 834-$542 930) compared with private practice surgeons (average experience = 3.2 years) who earned $233 020 (range, $115 000-$454 448). CONCLUSION: Salaries and compensation benefits of graduates of the FMIGS are varied. This information is very relevant to those attempting to hire or become employed as gynecologic surgical specialists.

RESUMO

Essure hysteroscopic sterilization has been US Food and Drug Administration-approved in the United States since 2002. Complications associated with the Essure device include improper placement (malpositioning), unintended pregnancy, pain, infection, and nickel allergy. The rarity of complications, compounded by underreporting, makes it difficult to determine best practices insofar as management. This systematic review synthesizes the national and global experience with management of Essure-related complications and suggests treatment options when data allow.

RESUMO

OBJECTIVE: To describe novel innovations and techniques for the detection of high-grade dysplasia. MATERIALS AND METHODS: Studies were identified through the PubMed database, spanning the last 10 years. The key words (["computerized colposcopy" or "digital colposcopy" or "spectroscopy" or "multispectral digital colposcopy" or "dynamic spectral imaging", or "electrical impedance spectroscopy" or "confocal endomicroscopy" or "confocal microscopy"or "optical coherence tomography"] and ["cervical dysplasia" or cervical precancer" or "cervix" or "cervical"]) were used. The inclusion criteria were published articles of original research referring to noncolposcopic evaluation of the cervix for the detection of cervical dysplasia. Only English-language articles from the past 10 years were included, in which the technologies were used in vivo, and sensitivities and specificities could be calculated. RESULTS: The single author reviewed the articles for inclusion. Primary search of the database yielded 59 articles, and secondary cross-reference yielded 12 articles. Thirty-two articles met the inclusion criteria. CONCLUSIONS: An instrument that globally assesses the cervix, such as computer-assisted colposcopy, optical spectroscopy, and dynamic spectral imaging, would provided the most comprehensive estimate of disease and is therefore best suited when treatment is preferred. Electrical impedance spectroscopy, confocal microscopy, and optical coherence tomography provide information at the cellular level to estimate histology and are therefore best suited when deferment of treatment is preferred. If a device is to eventually replace the colposcope, it will likely combine technologies to best meet the needs of the target population, and as such, no single instrument may prove to be universally appropriate. Analyses of false-positive rates, additional colposcopies and biopsies, cost, and absolute life-savings will be important when considering these technologies and are limited thus far.

RESUMO

The aim of this review was to estimate the incidence of urinary tract injuries associated with laparoscopic hysterectomy and describe the long-term sequelae of these injuries and the impact of early recognition. Studies were identified by searching the PubMed database, spanning the last 10 years. The key words "ureter" or "ureteral" or "urethra" or "urethral" or "bladder" or "urinary tract" and "injury" and "laparoscopy" or "robotic" and "gynecology" were used. Additionally, a separate search was done for "routine cystoscopy" and "gynecology." The inclusion criteria were published articles of original research referring to urologic injuries occurring during either laparoscopic or robotic surgery for gynecologic indications. Only English language articles from the past 10 years were included. Studies with less than 100 patients and no injuries reported were excluded. No robotic series met these criteria. A primary search of the database yielded 104 articles, and secondary cross-reference yielded 6 articles. After reviewing the abstracts, 40 articles met inclusion criteria and were reviewed in their entirety. Of those 40 articles, 3 were excluded because of an inability to extract urinary tract injuries from total injuries. Statistical analysis was performed using a generalized linear mixed effects model. The overall urinary tract injury rate for laparoscopic hysterectomy was 0.73%. The bladder injury rate ranged from 0.05% to 0.66% across procedure types, and the ureteral injury rate ranged from 0.02% to 0.4% across procedure type. In contrast to earlier publications, which cited unacceptably high urinary tract injury rates, laparoscopic hysterectomy appears to be safe regarding the bladder and ureter.
