Therapeutic Obstinacy in End-of-Life Care-A Perspective of Healthcare Professionals from Romania.

Background: End-of-life care raises ethical, moral, legal and economic dilemmas, especially when physicians have to decide whether to initiate or to stop treatments that may be considered disproportionate and futile.

Aim: To explore the opinion of health care professionals involved in end-of-life patient care on interventions considered disproportionate and futile at this stage of care, the causes and factors of pressure leading to such situations, and possible solutions to reduce the phenomenon.

Material And Method: The study used an adapted, designed questionnaire intended for health professionals caring for patients at the end of life.

Experimental Study on Rats with Critical-Size Bone Defects Comparing Effects of Autologous Bone Graft, Equine Bone Substitute Bio-Gen Alone or in Association with Platelet-Rich Fibrin (PRF).

Background: A critical-sized bone defect (CsBD) is considered one that will not heal spontaneously and requires reconstruction. This study aims to compare the results of using different bone reconstructive techniques and to study the potential of platelet-rich fibrin (PRF) to enhance the healing properties of a bone substitute (BS).

Methods: In this experimental study on rats, the treatment of critical-sized bone defects was carried out by analysing four groups: a control group in which the bone defect was left empty; a group treated with Bio-Gen; another group in which the defect was treated with PRF in combination with Bio-Gen; and the last that was treated with autologous bone graft (ABG).

A multi-species, multi-pathogen avian viral disease outbreak event: Investigating potential for virus transmission at the wild bird - poultry interface.

A free-range organic broiler () premises in Staffordshire was infected by high pathogenicity avian influenza virus (HPAIV) H5N8 during the 2020-2021 epizootic in the United Kingdom (UK). Following initial confirmation of the infection in poultry, multiple wild bird species were seen scavenging on chicken carcasses. Detected dead wild birds were subsequently demonstrated to have been infected and succumbed to HPAIV H5N8.

Effect of intranasal sufentanil on acute post-traumatic pain in the emergency department: a randomised controlled trial.

Background: Intranasal sufentanil is a potent opioid which can be used in patients with traumatic injuries presenting to the ED. Although previous studies have demonstrated the superiority of intranasal sufentanil over intravenous morphine in terms of pain relief, its clinical superiority in patients with traumatic injuries receiving adequate multimodal analgesia with acetaminophen and non-steroidal anti-inflammatory drugs is uncertain. We compared pain relief offered by intranasal sufentanil with that offered by oral and intravenous opioids in patients with acute traumatic injuries also receiving a specified regimen of non-opioid treatment.

Functional Surfaces via Laser Processing in Nickel Acetate Solution.

This study presents a novel laser processing technique in a liquid media to enhance the surface mechanical properties of a material, by thermal impact and micro-alloying at the subsurface level. An aqueous solution of nickel acetate (15% wt.) was used as liquid media for laser processing of C45E steel.
