Multidisciplinary approach to pelvic leiomyomatosis with intracaval and intracardiac extension: A case report and review of the literature.

Intravenous leiomyomatosis (IVL) is an uncommon variant of leiomyoma characterized by intravascular proliferation of a histologically benign smooth muscle tumor extending beyond the uterus into the distant great vessels. Leiomyomatosis may reach the inferior vena cava, right atrium, and pulmonary arteries. Owing to its rare occurrence, intracardiac leiomyomatosis has been reported as isolated case reports and small case series. Early diagnosis and prompt surgical intervention are vital to prevent cardiac symptoms, pulmonary embolism, and sudden death. Complete tumor resection is essential for a favorable outcome, usually assisted with multimodal surgical imaging and multidisciplinary surgical planning. Herein, we report the case of a 50-year-old female that presented with a three-month history of abdominal pain and lower extremity edema with evidence of IVL extending to the inferior vena cava and right atrium. The patient was managed with a single-stage surgery involving cardiopulmonary bypass and excision of the right atrial and inferior vena cava tumors, as well as modified radical total abdominal hysterectomy and bilateral salpingo-oophorectomy.

Carcinomatosis in Early-Stage Cervical Cancer Treated with Robotic Radical Hysterectomy: Recurrence Patterns, Risk Factors, and Survival.

PURPOSE: Minimally invasive radical hysterectomy has been associated with increased recurrence of disease and worse survival compared with open radical hysterectomy for early-stage cervical cancer. We evaluated patterns of recurrence and histopathologic risk factors in patients who underwent robotic radical hysterectomy (RRH). METHODS: Patients who underwent RRH (4/2007-12/2018) were evaluated for specific locations of recurrent disease, disease-free survival, overall survival (OS), and histopathologic risk factors for recurrence. Inclusion criteria were follow-up ≥ 1 year, histology with adenocarcinoma, adenosquamous, or squamous carcinoma and clinical stage IA2 to IB ≤ 4-cm tumor size cervical cancers (FIGO-2018). RESULTS: A total of 140 patients underwent RRH and 112 met criteria. Median tumor size was 2.1 cm [interquartile range (IQR): 1.1-3.3]. Median follow-up was 61 months (IQR: 36-102). Fifty (45%) patients underwent adjuvant radiation ± cisplatin with either Sedlis' or Peters' risk factors. There were 11 (9.8%) recurrences with median disease-free survival of 12 (IQR 8.5) months. All patients with recurrence had measured tumor size ≥ 2 cm (median tumor size 3-cm (IQR: 2.6-4.0). Tumor size > 2 cm was associated with Sedlis' intermediate-risk factors (p < 0.05) and Peters' high-risk factors (p < 0.05). Forty patients underwent preoperative conization, and two (5%) with deep positive margins in lesions > 2 cm recurred. Five (4.5%) of patients had carcinomatosis representing 45% of all recurrences. Carcinomatosis was associated with reduced OS compared with other recurrence patterns (22 months vs. 7.8 years, p < 0.05). CONCLUSIONS: Carcinomatosis was observed in early-stage cervical cancers treated with RRH and was associated with reduced OS. All recurrences were associated with lesions ≥ 2 cm, and no recurrences were identified with negative conization margins.

Low-threshold Buprenorphine Treatment in a Syringe Services Program: Program Description and Outcomes.

OBJECTIVES: Low-threshold buprenorphine treatment aims to reduce barriers to evidence-based opioid use disorder treatment. We aimed to describe the treatment philosophy, practices, and outcomes of a low-threshold syringe services program (SSP)-based buprenorphine program developed through an SSP-academic medical center partnership. METHODS: We included all SSP participants who received 1 or more buprenorphine prescription from Feb 5, 2019 to October 9, 2020. We collected data on patient characteristics, substance use, buprenorphine prescriptions, and urine drug tests (UDTs). We evaluated buprenorphine treatment retention using prescription data and buprenorphine adherence using UDTs. We used 2 retention definitions: (1) percentage of patients with buprenorphine prescriptions at 30, 90, and 180 days; and (2) total percentage of days "covered" with buprenorphine prescriptions through 180 days. RESULTS: One-hundred and eighteen patients received 1 or more buprenorphine prescriptions. Patients were largely middle-aged (mean age 44, standard deviation 11), male (68%), Hispanic (31%) or Non-Hispanic Black (32%), with heroin (90%) and crack/cocaine (62%) use, and injection drug use (59%). Retention was 62%, 43%, and 31% at 30, 90, and 180 days, respectively. The median percentage of days covered with buprenorphine prescriptions through 180 days was 43% (interquartile range 8%-92%). Of the 82 patients who completed 2 or more UDTs, the median percentage of buprenorphine-positive UDTs was 71% (interquartile range 40%-100%). CONCLUSIONS: In an SSP-based low-threshold buprenorphine treatment program, approximately one-third of patients continued buprenorphine treatment for 180 days or more, and buprenorphine adherence was high. SSPs can be a pathway to buprenorphine treatment for patients at high risk for opioid-related harms.

Interest in long-acting injectable buprenorphine among syringe services program participants.

OBJECTIVE: To examine syringe services program (SSP) participants' interest in long-acting injectable buprenorphine. DESIGN: SSP participants completed a 136-item questionnaire by phone. Items assessed quantitative ratings of interest in sublingual and injectable buprenorphine, preference for sublingual versus injectable buprenorphine, and reasons for preferences. SETTING: Two large urban SSPs. PARTICIPANTS: SSP participants ≥18 years of age with current or lifetime opioid use disorder (OUD). MAIN OUTCOME MEASURE(S): (1) Interest in sublingual and injectable buprenorphine, respectively, on a scale from 0 to 10 (0 = no interest and 10 = high interest); and (2) preference for sublingual buprenorphine versus injectable buprenorphine. Participants were also asked whether they agreed with statements that presented potential reasons for preferring each formulation. RESULTS: A total of 104 unique participants were interviewed, of which 72 (69 percent) were currently receiving or considering buprenorphine treatment. Among these 72 participants, the median level of interest in starting or continuing sublingual buprenorphine was 8 out of 10 (interquartile range [IQR]: 6-10) and in starting injectable buprenorphine was 5 out of 10 (IQR: 1-9). Thirty-six (50 percent) preferred sublingual, 27 (38 percent) preferred injectable, and 9 (13 percent) preferred neither or declined to answer. Participants who preferred injectable buprenorphine most commonly agreed that the convenience of the monthly injection was the reason for their preference. CONCLUSIONS: Among SSP participants with OUD, we found moderate interest in injectable buprenorphine. Introducing this new form of buprenorphine treatment at SSPs could help meet the needs of individuals who are not well-served by standard OUD treatment models.

"The Doctor Says You Cannot Have [Buprenorphine]" Autonomy and Use of Prescribed or Non-Prescribed Buprenorphine.

BACKGROUND: People may overcome barriers to professional buprenorphine treatment by using non-prescribed buprenorphine (NPB) to manage opioid use disorder (OUD). Little is known about how people perceive NPB differently than formal treatment. This qualitative study investigated how and why people use NPB as an alternative to formal treatment. METHODS: In-depth, semi-structured interviews were conducted with participants of harm reduction agencies (N = 22) who had used buprenorphine. Investigators independently coded transcribed interviews, generating themes through iterative reading and analysis of transcripts. RESULTS: Three main factors drove decisions about prescribed and non-prescribed buprenorphine use: 1) autonomy; 2) treatment goals; and 3) negative early experiences with NPB. An overarching theme from our analysis was that participants valued autonomy in seeking to control their substance use. NPB was a valuable tool toward this goal and professional OUD treatment could impede autonomy. Participants mostly used NPB to "self-manage" OUD symptoms. Many participants had concerns about long-term buprenorphine treatment and instead used NPB over short periods of time. Several participants also reported negative experiences with NPB, including symptoms of withdrawal, which then deterred them from seeking out professional treatment. CONCLUSIONS: These results support prior studies showing that people use NPB to self-manage withdrawal symptoms and to reduce use of illicit opioids. Despite these benefits, participants focused on short-term goals and negative consequences were common. Increasing buprenorphine treatment engagement may require attention to patients' sense of autonomy, and also assurance that long-term treatment is safe, effective, and reliably accessible.

Achieving Hepatitis C Elimination By Using Person-Centered, Nurse-Led Models of Care: A Discussion of Four International Case Studies.

Nurse-led models of care are an important strategy in the management of patients with chronic disease because of the person-centered approach that allows the needs of the individual to be prioritized and addressed in accessible settings. Hepatitis C is caused by a blood-borne virus that can cause liver disease and liver cancer; it predominantly affects marginalized populations, including people who inject drugs. Since 2013, all oral, direct-acting antiviral regimens have been available to cure hepatitis C. Nurses are well placed to be involved in the delivery of hepatitis C testing and treatment because of their extensive reach within marginalized communities and holistic approach to patient care. Four case studies of nurse-led models of care operating in Australia, Canada, the United Kingdom, and the United States are presented to illustrate the important role nurses have in delivering accessible, person-centered hepatitis C testing and treatment. Each case study demonstrates the success of overcoming barriers to hepatitis C testing and treatment such as geographic isolation, incarceration, social marginalization, and inflexible healthcare systems. Achieving the global target to eliminate hepatitis C by 2030 will require the nursing profession to embrace its role as the first point of contact to the healthcare system for many members of marginalized communities potentially at risk of hepatitis C. Nurses are well placed to reduce barriers and facilitate access to healthcare by scaling up activities focused on hepatitis C testing and treatment.

Robotic sentinel lymph node (SLN) mapping in endometrial cancer: SLN symmetry and implications of mapping failure.

PURPOSE: To establish the bilateral pelvic concordance rate of the sentinel lymph node (SLN) and determine the likelihood of lymph node metastasis in cases of mapping failure. METHODS: A database analysis was performed on 414 patients with clinical stage I endometrial cancer who underwent SLN mapping followed by robotic hysterectomy and completion pelvic (n=414, 100%) and aortic (n=186, 44.9%) lymphadenectomy from March 2011 to August 2016. Stage, histology, SLN sites, and surgico-pathologic findings were analyzed. The bilateral concordance rate of SLN location, successful unilateral and bilateral mapping rates, false negative rate, and non-SLN metastasis associated with mapping failure were calculated. RESULTS: Histologies included 354 (85.5%) endometrioid, 39 (9.4%) serous, 16 (3.9%) carcinosarcoma, 4 (1.0%) clear cell, and 1 (0.2%) undifferentiated. Final stages included 262 (63.3%) IA, 36 (8.7%) IB, 15 (3.6%) II, 6 (1.4%) IIIA, 68 (16.4%) IIIC1, and 27 (6.5%) IIIC2. Bilateral SLN mapping was successful in 355 (85.7%) patients, and 266 (74.9%) demonstrated mapping to the symmetrical lymphatic group contralaterally. The mapping failure rate was 13.5% (56/414) unilaterally and 0.7% (3/414) bilaterally. SLN locations were external iliac (69.1%), obturator (25.1%), internal iliac (2.2%), common iliac (1.9%), pre-sacral (0.9%), aortic (0.4%), parametrial (0.3%), and para-rectal (0.1%). Lymph node metastases were identified in 95 (22.9%) pelvic and 27 (6.5%) aortic nodes. 10 (16.9%) cases with mapping failure had lymph node metastasis on completion lymphadenectomy, similar to the proportion of SLNs with metastases (p=0.35). However, macro-metastases were more common in mapping failure completion lymphadenectomies than in the positive SLNs (80% vs 22.3%, p<0.001). CONCLUSION: The contralateral SLN location concordance rate was 75%. Most SLNs were along the medial external iliac or obturator locations. The rate of positive lymph nodes associated with SLN mapping failure was 16.9%, similar to the overall node-positive rate. The detection of pelvic node metastasis with SLN mapping failure was largely populated with macro-metastases and confirms the necessity of completion lymphadenectomy with mapping failure.

Clinical characteristics of pregnant women with influenza-like illness during the 2009 H1N1 pandemic and use of a standardized management algorithm.

We sought to describe the clinical characteristics of pregnant women with influenza-like illness during the 2009 H1N1 pandemic with the use of a standardized management algorithm. From June 2009 through March 2010, we assembled a prospective cohort of pregnant women with influenza-like illness at a single tertiary care center using a standardized algorithm. Clinical outcomes were compared between women with 2009 H1N1 virus and those without. In all, 45 women were included. Seventeen had 2009 H1N1 infection and 28 did not. Demographic characteristics were similar between groups. The median temperature upon presentation (99.7 vs 98.8°F, P = .004) was slightly higher among those with 2009 H1N1. All those with 2009 H1N1 influenza and 89% of those without were treated with oseltamivir. A total of 12 women (27%) were hospitalized. There were no endotracheal intubations or deaths. Among this cohort of pregnant women, most were treated as outpatients and had favorable maternal outcomes.

Subtle perturbations of genital microflora alter mucosal immunity among low-risk pregnant women.

OBJECTIVE: Alteration in the vaginal flora has been associated with adverse pregnancy outcomes. The objective of this study was to examine the impact of changes in individual microflora on genital immunity among low-risk pregnant women in early pregnancy. DESIGN: Cross-sectional study. SETTING: Large, tertiary care, academic hospital clinic. POPULATION: Low-risk women were enrolled prior to 14 weeks' gestation. METHODS: Women were included if they had no medical or previous obstetrical complications, were non-smokers, had no sexually transmitted infections and no intercourse in the last 48 hours. Consenting women underwent speculum examination for collection of vaginal culture and Dacron swabs for cytokine analysis. Semi-quantitative vaginal cultures were performed in a reference laboratory. MAIN OUTCOME MEASURES: Concentrations of immune mediators were compared in the presence of various organisms. Concentrations were converted to multiples of the median to standardize the values of each mediator. Regression analyses were performed to control for race. RESULTS: We enrolled 47 women. The frequencies of genital microorganisms were: H(2)O(2) -producing lactobacilli (70%), Ureaplasma urealyticum (66%), Gardnerella vaginalis (45%), anaerobic non-pigmented Gram-negative rods (ANPGNR, 40%), anaerobic pigmented Gram-negative rods (APGNR, 17%). After adjusting for race and body mass index, interleukin-1ß, interferon-γ, tumor necrosis factor-α and granulocyte macrophage-colony stimulating factor were increased in the presence of G. vaginalis, ANPGNR, and APGNR. There was no consistent impact on the other markers of immune activation. CONCLUSION: The presence of individual species impacts genital immunity among low-risk pregnant women. Perturbations in genital immunity could partially explain heterogeneity in adverse pregnancy outcomes.
