This article discusses the unexpectedly firm stance professed by John Paul II on the provision of artificial nutrition and hydration to patients who are in a persistent vegetative state, and it implications on previously held standards of judging medical treatments. The traditional ordinary/extraordinary care distinction is assessed in light of complexities of the recent allocution as well as its impact on Catholic individuals and in Catholic health care facilities. Shannon concludes that the papal allocution infers that the average Catholic patient is incapable of making proper judgments about their own care. Shannon sees the preservation of life at all costs as at least highly troubling, if not as a radical move against the Catholic medical ethics tradition.

Readily available animal tissue, such as ground beef, is a convenient material to represent the dielectric properties of biological tissue when validating microwave imaging and sensing hardware and techniques. The reliable use of these materials depends on the accurate characterization of their properties. In this work, the effect of physiologically relevant levels of dehydration on ex vivo tissue samples is quantified while controlling for variation within and between samples.

Due to imbalanced demand favoring egg whites, the egg industry faces a surplus of egg yolk, limiting overall growth. This study designed a feasible process for the crude extraction of livetins and phosvitin (PV) and revealed the related separation mechanisms. Our method utilized a 1:9 egg yolk dilution at pH 6.

Although glycine is the simplest of the amino acids, its solution and solid-state properties are far from straightforward. The aqueous solubility of glycine plays an important role in various applications, including nutrition, food products, biodegradable plastics, and drug development. There is evidence that glycine in subsaturated pH 3-8 solutions forms a dimer, as suggested by several techniques.

Background/objectives: Caring for patients at the end of life can involve issues that are ethically and legally fraught: withholding or withdrawing artificial nutrition and hydration, pain control that could hasten death, aggressive treatment that is continued when it seems only to be prolonging suffering, patients who request medical assistance in dying, and so forth. Clinicians may find that their deeply held ethical principles conflict with law, institutional policy, or patients' choices. In these situations, they may consider either refusing to participate in procedures that they find morally abhorrent (conscientious refusal) or providing care that they believe to be ethically obligatory despite being contrary to law or policy (conscientious commitment).

Background: The importance of nutritional status is underappreciated in patients with heart failure (HF). This study aimed to describe the range of the prognostic nutrition index (PNI), and the clinical characteristics and outcomes according to PNI, in patients with HF with preserved ejection fraction (HFpEF) and reduced ejection fraction (HFrEF). The primary outcome was the composite of HF hospitalization or cardiovascular death.
