When stored at chill temperatures, vacuum-packed (VP) lamb has a much shorter shelf-life than VP beef, primarily due to its higher pH, which could be linked to the higher fat content. The higher pH would create more favourable conditions for the growth of spoilage bacteria, resulting in a shorter shelf-life of meat. To determine the effects of fat on meat shelf-life as it relates to pH, a series of shelf-life trials at 2 °C were conducted using VP beef and lamb mince with varying fat contents (i.

Article Synopsis
- - Understanding the shelf-life difference between chilled vacuum-packed (VP) lamb and beef is crucial, as lamb has about half the shelf-life, leading to financial risks for the industry due to spoilage during shipping.
- - Key factors influencing the microbial spoilage of VP lamb include pH, fat content, and the presence of bone, which contribute to its shorter shelf-life when compared to VP beef.
- - The review identifies gaps in research on spoilage mechanisms and suggests further studies on the effects of fat and bone, as well as changes in meat metabolome, to improve the shelf-life of VP lamb.
Student nurses' educational experiences during COVID-19: A qualitative study.
Nurse Educ Today
December 2022
Background: Due to the COVID-19 pandemic, many unexpected changes occurred in healthcare. With the abrupt change to online education in 2020, nursing students experienced challenges with virtual learning which impacted their perception of preparedness to practice. There were few qualitative studies completed in the U.

The objective of this study was to establish whether specific organisms play important roles in the spoilage rate of vacuum-packed (VP) lamb at low storage temperatures. The spoilage potential of representative organisms (n = 13) of the spoilage community of VP lamb were investigated through a series of shelf-life challenge trials. Each isolate was individually inoculated onto sterile (irradiated) and non-sterile (i.

Objective: Our primary goal was to determine the diagnostic accuracy of the parasternal long axis (PSLA) view in isolation for identifying pericardial effusion, left ventricular (LV) dysfunction, and right ventricular (RV) dilatation compared with a four-view FOCUS examination.
Methods: This was a retrospective study looking at FOCUS images.
