PURPOSE

We investigated the relationship between obesity, menopausal status, and invasive lobular carcinoma (ILC), the second most common histological subtype of breast cancer. Specifically, we evaluated the association between body mass index (BMI), metabolic syndrome, the 21-gene Oncotype Recurrence Score (Oncotype RS), and pathological features in patients with hormone receptor (HR)-positive, human epidermal growth factor receptor-2-negative ILC.

METHODS

The study cohort included 491 patients from a prospectively maintained institutional database consisting of patients with stage I-III, HR-positive ILC who underwent surgical treatment between 1996 and 2019.

RESULTS

Contrary to our expectations, we found that lower BMI was significantly associated with having higher Oncotype RS (18.9% versus 4.8%, p = 0.028) in post-menopausal patients, but was not related to tumor characteristics in pre-menopausal patients. Multivariate network analyses suggested a strong relationship between post-menopausal status itself and tumor characteristics, with lesser influence of BMI.

CONCLUSION

These findings provide further insight into the recently appreciated heterogeneity within ILC and support the need for further investigation into the drivers of this disease and tailored treatment strategies.

We report a case of vaccine-induced immune thrombotic thrombocytopenia (VITT) in a young man diagnosed 13 days after Ad26.COV2.S COVID-19 (Johnson & Johnson/Janssen) vaccination. He presented to us with 5 days of progressive left leg pain, thrombocytopenia, hypofibrinogenemia, and markedly elevated d-dimers, but without radiographically demonstrable thrombosis. Despite negative imaging, we initiated treatment of presumptive VITT given the striking clinical picture that included the timing of his recent adenovirus-based COVID-19 vaccine, leg symptoms, marked thrombocytopenia, and consumptive coagulopathy. He received intravenous immune globulin, prednisone, and argatroban and was discharged 7 days later much improved. His positive platelet factor 4 enzyme-linked immunosorbent assay antibody test returned after treatment was initiated. To our knowledge, this is the first reported case of VITT following Ad26.COV2.S vaccination presenting without radiographically demonstrable thrombosis. Our patient highlights the importance of knowing vaccine status and initiating treatment as soon as possible in the right clinical setting, even in the absence of radiographic evidence of thrombus. Early VITT recognition and treatment provide an opportunity to prevent serious thrombotic complications.

OBJECTIVE

To assess risk factors associated with 30-day hospital readmission after a prolonged neonatal intensive care stay.

STUDY DESIGN

Retrospective analysis of 57,035 infants discharged >14 days from the NICU between 2013 and 2016. Primary outcome was 30-day, all-cause hospital readmission. Adjusted likelihood of readmission accounting for demographic and clinical characteristics, including chronic conditions was also estimated.

RESULTS

The 30-day readmission rate was 10.7%. Respiratory problems accounted for most (31.0%) readmissions. In multivariable analysis, shunted hydrocephalus [OR 2.2 (95%CI 1.8-2.7)], gastrostomy tube [OR 2.0 (95%CI 1.8-2.3)], tracheostomy [OR 1.5 (95%CI 1.2-1.8)], and use of public insurance [OR 1.3 (95%CI 1.2-1.4)] had the highest likelihood of readmission. Adjusted hospital readmission rates varied significantly (p  0.001) across hospitals.

CONCLUSIONS

The likelihood of hospital readmission was highest for infants with indwelling medical devices and public insurance. These findings will inform future initiatives to reduce readmission for high risk infants with medical and social complexity.
