Inflammatory bowel disease in pregnancy and breastfeeding.

Inflammatory bowel disease (IBD) has a peak age of diagnosis before the age of 35 years. Concerns about infertility, adverse pregnancy outcomes, and heritability of IBD have influenced decision-making for patients of childbearing age and their care providers. The interplay between the complex physiology in pregnancy and IBD can affect placental development, microbiome composition and responses to therapy.

Unfair Advantages for Hepatocellular Carcinoma Patients Listed for Liver Transplant in Short-Wait Regions Following 2015 Hepatocellular Carcinoma Policy Change.

For patients with hepatocellular carcinoma (HCC) listed for liver transplantation (LT), United Network for Organ Sharing (UNOS) enacted policy changes in 2015 to improve equity between HCC and non-HCC patients. We evaluated the impact of these changes on regional disparities in wait-list dropout and LT. We included patients in the UNOS database listed with Model for End-Stage Liver Disease HCC exceptions in long-wait regions (LWRs), mid-wait regions (MWRs), and short-wait regions (SWRs) before these policy changes (era 1, January 1 to December 31, 2013) and after (era 2, October 7, 2015, to October 7, 2016).

Disseminated Acanthamoeba infection in a heart transplant recipient treated successfully with a miltefosine-containing regimen: Case report and review of the literature.

Disseminated acanthamoebiasis is a rare, often fatal, infection most commonly affecting immunocompromised patients. We report a case involving sinuses, skin, and bone in a 60-year-old woman 5 months after heart transplantation. She improved with a combination of flucytosine, fluconazole, miltefosine, and decreased immunosuppression.

A bottom up approach to on-road CO2 emissions estimates: improved spatial accuracy and applications for regional planning.

On-road transportation is responsible for 28% of all U.S. fossil-fuel CO2 emissions.

Mapping urban pipeline leaks: methane leaks across Boston.

Natural gas is the largest source of anthropogenic emissions of methane (CH(4)) in the United States. To assess pipeline emissions across a major city, we mapped CH(4) leaks across all 785 road miles in the city of Boston using a cavity-ring-down mobile CH(4) analyzer. We identified 3356 CH(4) leaks with concentrations exceeding up to 15 times the global background level.

Modeling and validation of on-road CO2 emissions inventories at the urban regional scale.

On-road emissions are a major contributor to rising concentrations of atmospheric greenhouse gases. In this study, we applied a downscaling methodology based on commonly available spatial parameters to model on-road CO(2) emissions at the 1 × 1 km scale for the Boston, MA region and tested our approach with surface-level CO(2) observations. Using two previously constructed emissions inventories with differing spatial patterns and underlying data sources, we developed regression models based on impervious surface area and volume-weighted road density that could be scaled to any resolution.
