Location of Primary Tumor Impacts Survival After Pulmonary Metastasectomy for Colorectal Cancer.

Background: The benefit of pulmonary metastasectomy (PM) in patients with colorectal cancer (CRC) with isolated lung metastases remains unclear and failure to separate colon from rectal cancer may contribute. Utilizing a large national database, we investigate whether PM is associated with survival benefits in patients presenting with CRC with synchronous lung metastases based upon primary tumor location.

Methods: The Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2015 was queried to identify patients with stage IV CRC with isolated synchronous lung metastases at initial diagnosis.

Intraoperative cardiac arrest in patients undergoing congenital cardiac surgery.

Objective: To describe intraoperative cardiac arrest in patients undergoing congenital heart surgery.

Methods: The Society of Thoracic Surgeons Congenital Heart Surgery Database was queried. Predictors of intraoperative cardiac arrest were assessed using univariate and multivariable analyses.

Embryoscopy and targeted embryo biopsy for the management of early abortion.

Purpose: To evaluate the safety, accuracy, and effectiveness of embryoscopy for the management of early abortion and to test the hypothesis that targeted embryo and chorionic villi sampling avoids maternal cell contamination (MCC) for genetic testing of products of conception (POC).

Methods: This ambispective study included 74 consecutive patients presenting with early abortion. Gestations between 5 and 9 weeks, obtained either spontaneously or through assisted reproductive technologies were included.

Dynamics of PCV2 and PCV3 in the Serum and Oral Fluids of Pigs After PCV2 Vaccination in a Commercial Farm.

Objectives: This study investigated the dynamics of porcine circovirus type 2 (PCV2) and PCV3 on a commercial farm following PCV2 vaccination.

Methods: Serum samples from 35 pigs, starting at 3 weeks of age, were collected weekly until 21 weeks of age. Oral fluids from six pens of pigs of the same age were also analyzed.

Release of Biopolymers from Biomass Through Thermal and Non-Thermal Technologies.

Components of yeast cell walls, such as β-glucans and mannoproteins, show promise for developing sustainable biopolymers for food packaging. Efficient extraction, however, is challenging due to the complexity of the yeast cell wall. This study explored high-pressure homogenisation (HPH) and pulsed electric fields (PEFs), alone and with heat treatment (TT), on bakery yeast (BY) and brewery spent yeast (BSY) biomasses.
