Background/Objectives: Our objective was to describe the use of intraoperative radiation therapy (IORT) for the treatment of recurrent/persistent cervical or endometrial cancer and assess predictors of postoperative complications and 3-year mortality. Methods: In this multi-site retrospective study, data were abstracted for recurrent/persistent endometrial or cervical cancer patients who underwent IORT from June 2004 to May 2021. Complications were graded on the six-point Accordion scale. Variables associated with complications were analyzed with univariate logistic regression, while variables associated with death within 3 years were analyzed with Cox proportional hazards modeling. Survival was analyzed with the Kaplan–Meier method. Results: Eighty patients had planned IORT for recurrent/persistent endometrial (n = 35) or cervical cancer (n = 45). The mean age of the cohort was 56.8 years (SD = 13.7), and the median disease-free interval from primary disease to recurrence was 20.0 months (IQR 10.0–63.1). The overall survival at 3 years was 48.6% (95% CI: 38.3–61.6%) with a median survival of 2.8 years. Within 30 days postoperative, 16 patients (20.1%) had grade 3–5 complications and one death (1.3%) occurred. Factors associated with grade 3+ complication included ECOG PS 2–3 (OR 18.00, p = 0.04), neoadjuvant chemotherapy and/or immunotherapy (OR 6.98, p < 0.01), and pelvic sidewall involvement (OR 8.80, p = 0.04). Factors associated with death within 3 years of surgery included ECOG PS 2–3 (HR 8.97, p < 0.01), neoadjuvant chemotherapy and/or immunotherapy (HR 2.34, p = 0.03), whether exenteration was performed (HR 2.64, p = 0.01), and positive resection margin (HR 3.37, p < 0.01). Conclusions: In well-selected patients, IORT is a feasible and safe option for the treatment of recurrent/persistent gynecologic malignancy with an appreciable survival benefit.

INTRODUCTION: Several methods exist for diagnosis of preterm premature rupture of membranes (PPROM), including pooling on speculum exam, nitrazine test, arborization under microscopy, immunoassay, and amnio-dye test. Diagnostic accuracy is particularly important for PPROM because a missed diagnosis may result in life-threatening maternal and fetal consequences. We present a novel method for evaluating PPROM in equivocal cases using a menstrual cup. METHODS: Written informed consent was obtained for submission of a case report. A 36-year-old G6P5005 at 29 2/7 weeks presented with leakage of fluid. She was found to have negative pooling on speculum exam, negative arborization on microscopy, a maximum vertical pocket (MVP) of 4.0 cm, and a negative urinalysis. She was discharged with precautions and returned 2 days later with persistent symptoms. Workup again showed no pooling, no arborization, and a normal MVP. The patient suggested using a menstrual cup to capture her intermittent leakage of fluid. She wore a menstrual cup for 30 minutes in triage. A sample of the fluid tested positive for arborization. She was admitted to labor and delivery for latency antibiotics, betamethasone, and fetal and maternal monitoring. CONCLUSION: Preterm premature rupture of membranes can occur without overt vaginal pooling due to small volume leakage. Conventional testing is less sensitive when pooling is absent. In these cases, a menstrual cup may help facilitate diagnosis and avoid invasive tests such as the amnio-dye test. Care must be taken to use a clean menstrual cup without gel, limit the duration of menstrual cup use to avoid infection, and to distinguish arborization of amniotic fluid from that of cervical mucus.

Abstract Data evaluating change in body composition during treatment of advanced cancer are limited. Here we evaluated computed tomography (CT)–based changes in muscle mass during treatment for advanced ovarian cancer (OC) and association with outcomes. We analyzed the preoperative and posttreatment skeletal muscle index (SMI), skeletal muscle area normalized for height of 109 patients with advanced OC who underwent primary surgery and platinum-based chemotherapy from 2006 to 2016. Based on an SMI less than 39 cm2/m2, 54.1% of patients were never sarcopenic, 24.8% were sarcopenic on both CT scans, and 21.1% were newly sarcopenic upon treatment completion. Patients who lost muscle during treatment had the worst survival of the 3 groups identified: median survival 2.6 years vs 4.6 years if sarcopenic on both CT scans and 4.8 years if never sarcopenic. Loss of muscle portends a poor prognosis among patients with OC. Additional research is needed to better understand and best mitigate these changes.

Objective: To determine if gastrointestinal (GI) symptoms can predict deep endometriosis (DE) of the posterior pelvic compartment on magnetic resonance imaging (MRI). Methods: Patients with suspected endometriosis undergoing endometriosis protocol MRI at an academic center between 9/1/2015 and 7/31/2018 were identified. Presenting GI symptoms were collected via a standardized survey instrument prospectively at initial presentation. MRI and interdisciplinary conference notes were reviewed to identify posterior compartment DE (rectosigmoid, uterosacral ligaments, posterior cul de sac, and pelvic side walls). Associations between symptoms and DE were evaluated. Results: A total of 104 patients met inclusion criteria, and 89 (85.6%) presented with at least one GI symptom. Posterior compartment DE was identified on MRI in 47 patients (45.2%). The GI symptom that most strongly predicted DE was a bowel movement resulting in pain relief (OR 3.36, 95% CI 1.31–8.61, p = 0.012), with sensitivity, specificity, positive and negative predictive values 0.42, 0.82, 0.67, and 0.63, respectively. Other GI symptoms such as nausea, vomiting, rectal bleeding, change in frequency of bowel movements, and pain exacerbation by bowel movements did not significantly correlate to having DE. Of the 15 patients with no GI symptoms, 5 were found to have posterior compartment DE. Conclusion: In patients with suspected endometriosis, those who noted that bowel movements relieved their pain had more than three times the odds of having DE of the posterior compartment on MRI. Preoperative evaluation with MRI may be of value in these patients; however, lack of gastrointestinal symptoms does not exclude the possibility of posterior compartment DE.

On March 11, 2020, the World Health Organization declared coronavirus disease 2019 (COVID-19) a pandemic, and the reality of the situation has finally caught up to the widespread reach of the disease. The presentation of the disease is highly variable, ranging from asymptomatic carriers to critical COVID-19. The availability of angiotensin-converting enzyme 2 (ACE2) receptors may reportedly increase the susceptibility and/or disease progression of COVID-19. Comorbidities and risk factors have also been noted to increase COVID-19 susceptibility. In this paper, we hereby review the evidence pertaining to ACE2’s relationship to common comorbidities, risk factors, and therapies associated with the susceptibility and severity of COVID-19. We also highlight gaps of knowledge that require further investigation. The primary comorbidities of respiratory disease, cardiovascular disease, renal disease, diabetes, obesity, and hypertension had strong evidence. The secondary risk factors of age, sex, and race/genetics had limited-to-moderate evidence. The tertiary factors of ACE inhibitors and angiotensin II receptor blockers had limited-to-moderate evidence. Ibuprofen and thiazolidinediones had limited evidence.

Platelet-rich plasma (PRP) has become increasingly popular in pain medicine with hopes of becoming a safe, effective alternative to routine treatments. However, given its autologous nature, PRP injectate may differ depending on the specific manufacturer and protocol. Currently, there is no standardization of reporting protocol. This systematic review compiles and standardizes values on PRP preparation and final product composition of platelets, white cell count, and growth factors for ease of comparison. On review of 876 studies, 13 studies were selected according to our inclusion criteria. Data from 33 PRP systems and protocols were extracted and standardized. Overall, PRP final product concentrations as well as PRP preparation protocols varied widely between systems. However, platelet concentration was directly correlated with both volume of blood collected and device centrifugal force. In conclusion, there is a large heterogeneity between PRP separation systems that must be resolved for proper study of this promising treatment.

Abstract Background: Although the need for palliative care is gaining recognition in Southeast Asia, knowledge about how decisions are made for children near the end of life remains sparse. Objective: To explore pediatric intensivists' attitudes and practices surrounding end-of-life care in Vietnam. Methods: This is a mixed-methods study conducted at a tertiary pediatric and neonatal intensive care unit in Hanoi. Physicians and nurses completed a quantitative survey about their views on end-of-life care. A subset of these providers participated in semistructured interviews on related topics. Analysis of surveys and interviews were conducted. Results were triangulated. Results: Sixty-eight providers (33 physicians and 35 nurses) completed the quantitative survey, and 18 participated in interviews. Qualitative data revealed three overarching themes with numerous subthemes and supporting quotations. The first theme was factors influencing providers' decision-making process to escalate or withdraw treatment. Quantitative data showed that 40% of providers valued the family's ability to pay to continue life-sustaining treatment. Second, communication dynamics in decision making were highlighted; 72% of providers would be willing to override a family's wishes to withdraw life-sustaining treatment. Third, provider perceptions of death varied, with 68% regarding their patients' deaths as a personal failure. Conclusions: We elicited and documented how pediatric intensivists in Vietnam currently think about and provide end-of-life care. These findings indicate a need to strengthen palliative care training, increase family involvement in decision making, implement standardized and official do-not-resuscitate documentation, and expand pediatric hospice services at the individual, hospital, and national levels in Vietnam.
