Laparoscopic administration of bupivacaine at the uterosacral ligaments during benign laparoscopic and robotic hysterectomy: a randomized controlled trial.

BACKGROUND: Postoperative pain continues to be an undermanaged part of the surgical experience. Multimodal analgesia has been adopted in response to the opioid epidemic, but opioid prescribing practices remain high after minimally invasive hysterectomy. Novel adjuvant opioid-sparing analgesia to optimize acute postoperative pain control is crucial in preventing chronic pain and minimizing opioid usage. OBJECTIVE: This study aimed to determine the effect of direct laparoscopic uterosacral bupivacaine administration on opioid usage and postoperative pain in patients undergoing benign minimally invasive (laparoscopic and robotic) hysterectomy. STUDY DESIGN: This was a single-blinded, triple-arm, randomized controlled trial at an academic medical center between March 15, 2021, and April 8, 2022. The inclusion criteria were patients aged >18 years undergoing benign laparoscopic or robotic hysterectomy. The exclusion criteria were non-English-speaking patients, patients with an allergy to bupivacaine or actively using opioid medications, patients undergoing transversus abdominis plane block, and patients undergoing supracervical hysterectomy or combination cases with other surgical services. Patients were randomized in a 1:1:1 fashion to the following uterosacral administration before colpotomy: no administration, 20 mL of normal saline, or 20 mL of 0.25% bupivacaine. All patients received incisional infiltration with 10 mL of 0.25% bupivacaine. The primary outcome was 24-hour oral morphine equivalent usage (postoperative day 0 and postoperative day 1). The secondary outcomes were total oral morphine equivalent usage in 7 days, last day of oral morphine equivalent usage, numeric pain scores from the universal pain assessment tool, and return of bowel function. Patients reported postoperative pain scores, total opioid consumption, and return of bowel function via Qualtrics surveys. Patient and surgical characteristics and primary and secondary outcomes were compared using chi-square analysis and 1-way analysis of variance. Multiple linear regression was used to identify predictors of opioid use in the first 24 hours after surgery and total opioid use in the 7 days after surgery. RESULTS: Of 518 hysterectomies screened, 410 (79%) were eligible, 215 (52%) agreed to participate, and 180 were ultimately included in the final analysis after accounting for dropout. Most hysterectomies (70%) were performed laparoscopically, and the remainder were performed robotically. Most hysterectomies (94%) were outpatient. Patients randomized to bupivacaine had higher rates of former and current tobacco use, and patients randomized to the no-administration group had higher rates of previous surgery. There was no difference in first 24-hour oral morphine equivalent use among the groups (P=.10). Moreover, there was no difference in numeric pain scores (although a trend toward significance in discharge pain scores in the bupivacaine group), total 7-day oral morphine equivalent use, day of last opioid use, or return of bowel function among the groups (P>.05 for all). The predictors of increased 24-hour opioid usage among all patients included only increased postanesthesia care unit oral morphine equivalent usage. The predictors of 7-day opioid usage among all patients included concurrent tobacco use and mood disorder, history of previous laparoscopy, estimated blood loss of >200 mL, and increased oral morphine equivalent usage in the postanesthesia care unit. CONCLUSION: Laparoscopic uterosacral administration of bupivacaine at the time of minimally invasive hysterectomy did not result in decreased opioid usage or change in numeric pain scores.

Impact of Obesity on Clinical and Financial Outcomes of Minimally Invasive Hysterectomy for Benign Conditions.

OBJECTIVE: To evaluate the effect of obesity on clinical and financial outcomes of minimally invasive hysterectomy METHODS: This was a retrospective cohort study of 5 affiliated hospitals. We obtained demographic, operative, and financial characteristics to analyze the effects of obesity on outcomes, including operating room (OR) time, estimated blood loss (EBL), length of stay (LOS), adverse perioperative events, and hospital charges. Obesity was stratified by the following classes: no obesity (BMI <30 kg/m2), class I (BMI 30-34 kg/m2), class II (BMI 35-39 kg/m2), and class III (BMI >40 kg/m2). Descriptive statistics and multivariate logistic and linear regressions were performed. RESULTS: A total of 2483 women underwent benign, minimally invasive hysterectomy. Laparoscopic was the most common approach (79.8%), followed by robotic (12.2%), and vaginal (8.0%). Mean BMI was 30.13 ± 6.99 kg/m2, and total charges were US $13 928 ± $5954. Each additional minute in the OR increased costs by US $47.89 (P < 0.001). Compared with patients without obesity, OR time and EBL were significantly higher among patients with class I or II obesity and highest among patients with class III obesity (P < 0.001). Obesity did not affect LOS or occurrence of adverse perioperative events. Although obesity appeared to be a significant predictor of hysterectomy charges, after adjusting for covariates, charges for laparoscopic and robotic hysterectomy did not differ significantly by BMI. CONCLUSION: Obesity appears to have a significant effect on clinical outcomes of benign hysterectomy that is approach-dependent and most notable among patients with class III obesity. BMI was not, however, a predictor of financial outcomes.

Urinary Incontinence Care-Seeking Barriers Among Latina Patients: What Are We Missing?

IMPORTANCE: The Latina population is the largest growing ethnic group in the United States with high levels of health disparities in urinary incontinence (UI) treatment and complications rates, which may be due to disproportionately high barriers to UI care-seeking among Latinas. OBJECTIVES: The objectives of this study were to compare barriers to UI care-seeking among Latina, non-Latina Black, and non-Latina White patients by utilizing the Barriers to Incontinence Care Seeking Questionnaire (BICS-Q) total scores, and to compare specific barriers utilizing BICS-Q subscales. STUDY DESIGN: In this cross-sectional study, patients accessing primary care were recruited to complete the BICS-Q, International Consultation on Incontinence Questionnaire-Short Form, and Prolapse and Incontinence Knowledge Questionnaire-Urinary Incontinence. The BICS-Q total and subscale scores were compared among ethnic/racial groups. RESULTS: A total of 298 patients were included in the study with 83 Black, 144 Latina, and 71 White participants per self-identified ethnicity/race. The total BICS-Q score was highest for Latina participants, followed by White and Black participants (11.2 vs 8.2 vs 4.9, respectively, P < 0.0001). Latina participants had significantly higher BICS-Q subscale scores compared with Black participants with no significant differences between Latina and White participants. After controlling for potential confounders, Latina ethnicity/race was still associated with a higher BICS-Q score when compared to Black ethnicity/race (P = 0.0077), and lower Prolapse and Incontinence Knowledge Questionnaire-Urinary Incontinence scores remained independently associated with higher BICS-Q scores (P = 0.0078). CONCLUSIONS: In our study population, Latina patients and patients with lower UI knowledge experience higher barriers to UI care-seeking compared with Black patients and patients with higher UI knowledge. Addressing these barriers may increase care-seeking and improve health equity in the field.

Patient caught breastfeeding and instructed to stop: an empirical ethics study on marijuana and lactation.

BACKGROUND: The US guidelines recommend avoiding marijuana during breastfeeding given concerns about infant's neurodevelopment. In this setting, some physicians and hospitals recommend against or prohibit breastfeeding when marijuana use is detected during pregnancy. However, breastfeeding is beneficial for infants and women, and stigmatization of substance use in pregnancy has been historically linked to punitive approaches with a disproportionate impact on minority populations. We advance an empirically informed ethical analysis of this issue. METHODS: First, we performed a retrospective cross-sectional qualitative study of prenatal and postpartum records from a random sample of 150 women delivered in an academic hospital system in 2017 to provide evidence and context regarding breastfeeding management in relation to marijuana use. We then perform a scoping literature review on infant risks from breastmilk marijuana exposure and risks associated with not breastfeeding for infants and women. Finally, we analyze this issue vis-a-vis ethical principles of beneficence, autonomy, and justice. RESULTS: (1) Medical records reveal punitive language pertaining to the medicinal use of marijuana in pregnancy and misinterpretation of national guidelines, e.g., "patient caught breastfeeding and instructed to stop." (2) Though there are plausible neurodevelopmental harms from breastmilk exposure to THC, evidence of infant effects from breastmilk exposure to marijuana is limited and largely confounded by concomitant pregnancy exposure and undisclosed exposures. By contrast, health benefits of breastfeeding for women and infants are well-established, as are harms of forgoing breastfeeding. (3) Discouraging breastfeeding for women with marijuana use in pregnancy contradicts beneficence, as it neglects women's health considerations and incorrectly assumes that risks exceed benefits for infants. Restrictive hospital practices (e.g., withholding lactation support) compromise maternal autonomy and exploit power asymmetry between birthing persons and institutions, particularly when compulsory toxicology screening prompts child welfare investigations. Finally, recommending against breastfeeding during prenatal care and imposing restrictions during postpartum hospitalization may exacerbate racial disparities in breastfeeding and related health outcomes. CONCLUSIONS: Policy interpretations which discourage rather than encourage breastfeeding among women who use of marijuana may cause net harm, compromise autonomy, and disproportionately threaten health and wellbeing of underserved women and infants.

Creation and Implementation of Virtual Urogynecology Patient Cases for Medical Student Education.

Introduction: Urogynecologic disorders are highly prevalent, and many physicians across various specialties will encounter and care for patients with pelvic floor disorders. Yet most medical students have had limited to no experience in diagnosing and managing pelvic floor disorders, resulting in a gap in clinical education. Methods: Three virtual and interactive urogynecologic patient cases were developed on an e-learning platform with an overall goal of increasing clinical exposure to various pelvic floor disorders. The cases were integrated into the medical student obstetrics and gynecology clerkship during the 2020-2021 academic year (n = 40). Participants provided feedback regarding usability, acceptability, and educational value of the cases. Results: Twenty-one students (52%) completed the survey. Ninety percent (n = 19) agreed or strongly agreed that they were satisfied with the cases, and 71% (n = 15) agreed or strongly agreed that they would recommend the virtual patient cases to other students. All students (n = 21) felt that the format was easy to use and reported that the cases were appropriate for their level of learning. Most students felt that the cases increased or significantly increased their confidence regarding nonsurgical and surgical management options for pelvic floor disorders. Discussion: Our findings suggest that these interactive virtual patient cases are an acceptable, valuable, and effective tool for learners. Utilizing the cases can help mitigate existing disparities in exposure to pelvic floor disorders both highlighted by and preceding the COVID-19 pandemic.

Lost in Translation: The Role of Interpreters on Labor and Delivery.

During the Coronavirus (COVID-19) pandemic, in-person interpreters have been deemed "nonessential," and thus eliminated to minimize viral exposure and conserve personal protective equipment. Considering alarming patterns of interpreter underuse, we evaluate how substitution for remote modalities (telephone or video) may exacerbate existing inequalities for patients with limited English proficiency. The inherent intimacy, dynamic physicality, and cultural nuances of labor and delivery pose unique communication challenges. Using clinical scenarios, we illustrate the vital role interpreters have in providing accessible obstetric care. We argue that eliminating in-person interpreters in this setting is not justified by COVID-related harms given the potential to exacerbate underlying health disparities.

Double-strand break repair assays determine pathway choice and structure of gene conversion events in Drosophila melanogaster.

Double-strand breaks (DSBs) must be accurately and efficiently repaired to maintain genome integrity. Depending on the organism receiving the break, the genomic location of the DSB, and the cell-cycle phase in which it occurs, a DSB can be repaired by homologous recombination (HR), nonhomologous end-joining (NHEJ), or single-strand annealing (SSA). Two novel DSB repair assays were developed to determine the contributions of these repair pathways and to finely resolve repair event structures in Drosophila melanogaster. Rad51-dependent homologous recombination is the preferred DSB repair pathway in mitotically dividing cells, and the pathway choice between HR and SSA occurs after end resection and before Rad51-dependent strand invasion. HR events are associated with long gene conversion tracts and are both bidirectional and unidirectional, consistent with repair via the synthesis-dependent strand annealing pathway. Additionally, HR between diverged sequences is suppressed in Drosophila, similar to levels reported in human cells. Junction analyses of rare NHEJ events reveal that canonical NHEJ is utilized in this system.
