Effect of SeaFeed, a canola oil infused with , on methane emissions, animal health, performance, and carcass characteristics of Angus feedlot cattle.

The objectives of this project were to measure the effect of SeaFeed, a canola oil infused with , on methane emissions, animal health, performance, and carcass characteristics of feedlot cattle. Angus steers ( = 160) with an initial body weight of 474.4 kg were fed a steam-flaked wheat and barley ration for 200 d in a large, commercial feedlot.

Development of a single-visit protocol for the management of pregnancy of unknown location following in vitro fertilization: a retrospective study.

Study Question: Can women with pregnancy of unknown location (PUL) following in vitro fertilization (IVF) be risk-stratified regarding the subsequent need for medical intervention, based on their demographic characteristics and the results of serum biochemistry at the initial visit?

Summary Answer: The ratio of serum hCG to number of days from conception (hCG/C) or the initial serum hCG level at ≥5 weeks' gestation could be used to estimate the risk of women presenting with PUL following IVF and needing medical intervention during their follow-up.

What Is Known Already: In women with uncertain conception dates presenting with PUL, a single serum hCG measurement cannot be used to predict the final pregnancy outcomes, thus, serial levels are mandatory to establish a correct diagnosis. Serum progesterone levels can help to risk-stratify women at their initial visit but are not accurate in those taking progesterone supplementation, such as women pregnant following IVF.

Managing a new diagnosis of interstitial lung disease in pregnancy.

Interstitial lung disease (ILD) presents rarely in pregnancy. Reports have associated disease activity with higher rates of preeclampsia, preterm births and fetal loss. This case report describes a patient presenting in her fifth pregnancy with worsening dyspnoea.
