Analysis of factors predicting surgical intervention and associated costs in pediatric breast masses: a single center study.

PURPOSE: Finding a breast mass in a child provokes apprehension in parents, especially in those with a family history of breast cancer. Clinicians must decide between serial imaging or biopsy of the mass. Herein, we identify management differences in those with and without a positive family history, as well as identify cost differences. METHODS: An institutional retrospective review was performed of patients (2-18 years of age) with a diagnosis of breast mass. Patient demographics, presentation, medical and surgical history, physical exam, imaging, and pathologic diagnosis were collected. Cost data were acquired from the pediatric health information system (PHIS). Costs were compared between patients managed by biopsy versus serial ultrasounds. Bivariate analyses including Pearson's Chi-square, student's t tests, and logistic regression were performed. RESULTS: The probability of biopsy increases with age (p = 0.0001) and female gender (p = 0.006). Biopsy rate is higher for larger masses (p < 0.0001), growing size (p < 0.0001), and in patients with a positive family history of breast cancer (p < 0.0001). The average cost of care for management with initial excisional biopsy was $4491 versus those with serial ultrasounds ($986) (p < 0.0001). CONCLUSIONS: In patients with small lesions, even with a family history of breast cancer, non-operative monitoring is a safe and cost-effective alternative to invasive biopsy.

Toward operative in vivo fluorescence imaging of the c-Met proto-oncogene for personalization of therapy in ovarian cancer.

BACKGROUND: Standard biomarker testing of a single macroscopic disease site is unlikely to be sufficient because of tumor heterogeneity. A focus on examining global biomarker expression or activity, particularly in microscopic residual chemotherapy-resistant disease, is needed for the appropriate selection of targeted therapies. This study was aimed at establishing a technique for the assessment of biomarkers of ovarian cancer peritoneal spread. METHODS: An in-house developed fluorescent imaging device was used to detect the expression of the c-Met oncogene in ovarian cancer. A modified cyanine 5-tagged peptide, GE137, with a high in vitro affinity for the human c-Met protein, was tested in a panel of ovarian cancer cell lines. Finally, the feasibility of detecting submillimeter ovarian cancer cell peritoneal metastases in vivo was tested through the intravenous injection of GE137 into mice with tumor xenografts. RESULTS: Using optical imaging it was possible to detect c-Met expression in submillimeter peritoneal metastases that were freshly excised from a human high-grade serous ovarian cancer. GE137 selectively bound to the c-Met tyrosine kinase without activating survival signaling pathways (AKT or extracellular signal-regulated kinase phosphorylation) downstream of c-Met. GE137 specifically accumulated in SKOv3 ovarian cancer cells expressing c-Met via clathrin-mediated endocytosis and emitted a fluorescent signal that lasted for at least 8 hours in tumor xenografts in vivo with a sustained high signal-to-noise ratio. CONCLUSIONS: Our results suggest that intraoperative optical imaging could provide a new paradigm for selecting cancer patients for appropriate targeted therapies, particularly after initial chemotherapy.

Perspectives of women of refugee background on healthcare needs in a major urban metropolitan community in the US: A qualitative needs assessment.

The objective of this study was to describe the healthcare needs and experiences of women of refugee background in Chicago-home to one of the largest and most diverse refugee populations in the United States. We used a phenomenological study design with a desire-centered rather than damage-centered approach to conduct a series of focus group discussions with 24 women of refugee background in their native languages in Chicago, Illinois between December 2018 and February 2019. Convenience sampling was used to recruit women of refugee background at least 18 years of age living in the Chicago metropolitan area who attended educational women's health workshops at local refugee community centers. An inductive approach to the analysis was used to code transcripts and generate themes. Our study identified four major healthcare priorities for women of refugee background in a major metropolitan area: (1) central and centralised healthcare, (2) continuity of care, (3) trauma-informed care and (4) community engagement and partnerships. The healthcare priorities identified by the participants in this study should inform existing and future healthcare models and clinics providing care for women of refugee background in urban and sub-urban contexts across the United States.

The role of digital examination in the setting of a sonographically short cervix.

BACKGROUND: Universal transvaginal cervical length screening has been associated with a reduction in the frequency of preterm birth. However, there is no clinically set standard to guide the performance of a digital cervical examination in the setting of a sonographically short cervix. OBJECTIVE: To investigate the prevalence of cervical dilation at various midtrimester transvaginal cervical length thresholds. Furthermore, we sought to identify sonographic or clinical characteristics associated with cervical dilation that may inform who would benefit from a digital cervical examination in the setting of a sonographically short cervix. STUDY DESIGN: This retrospective cohort study was conducted at an academic institution and included women with a singleton gestation and an ultrasonographically detected short cervix (defined as a transvaginally obtained cervical length ≤25 mm) who had a documented digital cervical examination within 1 week of the ultrasonography. Bivariable analyses were used to determine the relationship between cervical length and the presence of cervical dilation. Multivariable logistic regression and receiver operating characteristic curve were used to evaluate the relationship between clinical and sonographic risk factors and cervical dilation. RESULTS: Of the 256 women who met eligibility criteria and had a sonographically detected short cervix, 103 (40.2%) were found to be dilated on digital cervical examination. The prevalence of cervical dilation increased as sonographic cervical length decreased; cervical dilation was identified in 15%, 39%, 53%, 64%, and 69% of women with a cervical length between 20.0 and 25.0 mm, 15.0 and 19.9 mm, 10.0 and 14.9 mm, 5.0 and 9.9 mm, and 0.0 and 4.9 mm, respectively. Maternal race or ethnicity (examined as a social construct), insurance status, nulliparity, previous cervical excisional procedure, funneling on ultrasonography, and sonographic cervical length were each associated with cervical dilation. However, including all of these variables into a regression yielded a model with only moderate predictive ability to identify cervical dilation, with receiver operating area under the curve of 0.77 (95% confidence interval, 0.71-0.83). CONCLUSION: Consideration should be given to performing a digital cervical examination in the setting of a sonographically short cervix (especially <20 mm) to detect cervical dilation.

Neonatal hypoglycemia after antenatal late preterm steroids in individuals with diabetes.

OBJECTIVE: To establish whether administration of antenatal late preterm steroids to pregnant people with diabetes resulted in higher risk of neonatal hypoglycemia. STUDY DESIGN: This is a retrospective cohort study of individuals with pre-gestational or gestational diabetes admitted between 34 0/7-36 6/7 weeks' gestation before and after introduction of an antenatal late preterm steroids protocol. The primary outcome was any neonatal blood glucose ≤ 60 mg/dL in the first 24 h of life. RESULTS: Of 123 mother-neonate pairs, 52.8% (N = 65) delivered during the post-protocol period; 75.4% of those (N = 49) received late preterm steroids. 59.7% (N = 34) of the pre-protocol neonates and 81.5% (N = 53) of the post-protocol neonates had hypoglycemia (p = 0.008). After controlling for gestational age at delivery and mode of delivery, neonates in the post-protocol group had increased odds of hypoglycemia (adjusted odds ratio 2.96, 95% confidence interval 1.29-6.82). CONCLUSION: Neonates born to mothers with diabetes who received late preterm corticosteroids experienced greater odds of hypoglycemia.

Implementation of an antenatal late-preterm corticosteroid protocol at a high-volume tertiary care center.

Background: Since publication of the sentinel antenatal late preterm steroids clinical trial, the use of antenatal steroids has become a routine aspect of the management of pregnancies at risk for late preterm delivery. However, in practice, the administration of antenatal corticosteroids in the late preterm period is widely varied across provider and institution, and the process of implementation of this new practice as well as outcomes associated with implementation are not well understood. Objective: The objective was to evaluate institutional adherence to an antenatal late preterm corticosteroid protocol and to assess neonatal outcomes associated with its introduction. Study Design: This is a retrospective cohort study of all women with singleton pregnancies admitted between 34 to 36 5/7 weeks who presented in the year before ("pre-protocol": November 2012 to October 2013) and after implementation ("post-protocol": April 2016 to March 2017). The protocol recommends corticosteroid administration to women 34 to 36 5/7 weeks gestation at risk for preterm birth who have not received prior corticosteroids. Women with fetal anomalies or pregestational or gestational diabetes were excluded from analysis. The frequency with which eligible women received corticosteroids and ineligible women were appropriately excluded (adherence) was calculated on a monthly basis. Neonatal outcomes of interest were hypoglycemia, receipt of dextrose, birth weight, 5 minute Apgar less than 7, receipt of surfactant, respiratory distress syndrome, transient tachypnea of the newborn, neonatal intensive care unit length of stay, intraventricular hemorrhage, necrotizing enterocolitis, culture positive sepsis, bronchopulmonary dysplasia, and death. Bivariable and multivariable analyses were used to compare neonatal outcomes between 1) all women in the post-protocol cohort to those in the pre-protocol cohort and 2) only women who received adherent care in the post-protocol cohort to all women in the pre-protocol cohort. Results: A total of 452 women were included in the pre-protocol cohort and 451 in the post-protocol cohort. The majority of the post-protocol women (N=366, 81.2%) received adherent care. Women in both cohorts were similar with the exception that women in the post-protocol cohort were more likely to be nulliparous (p=0.013). Compared to the pre-protocol period, neonates of women in the post-protocol period had significantly higher odds of hypoglycemia <50 mg/dL in the first 24 hours of life (aOR 1.37, 95% CI 1.05-1.80), without improvements in respiratory outcomes. Results were similar when restricting the analysis to only women in the post-protocol cohort who received care adherent care (glucose <50 mg/dL: aOR 1.52, 95% CI 1.14-2.03). No differences in composite respiratory morbidity or other neonatal outcomes were observed. Conclusion: Uptake of a new institutional protocol for antenatal late preterm corticosteroids was rapid. Compared with historic controls, neonates exposed to antenatal late preterm corticosteroid experienced increased odds of hypoglycemia, without significant improvements in respiratory morbidities.
