Complicity in an immoral, and even criminal, activity, such as robbery or murder, is itself regarded as involving responsibility for those acts. What should the position be of health professionals who are expected to participate in actions that they believe are morally wrong? Professional responsibilities may clash with private conscience. Even referring a patient to someone else, when what is in question may be assisted suicide, or euthanasia, seems to involve some complicity. This is a live issue in Canada, but similar dilemmas occur elsewhere...

BACKGROUND: Beliefs around deactivation of a left ventricular assist device (LVAD) vary substantially between clinicians, institutions, and patients. Therefore, we sought to understand perspectives regarding LVAD deactivation among cardiology and hospice/palliative medicine (HPM) clinicians. METHODS AND RESULTS: We administered a 41-item survey via electronic mail to members of 3 cardiology and 1 HPM professional societies. A convergent parallel mixed methods design was used...

In 2014, there was still a shortage of available organs for transplantation, and 1044 patients were waiting for an organ in the Netherlands. Maximizing the pool of organ donors is part of the solution. In 2001, the Dutch Termination of Life on Request and Assisted Suicide Act was adopted, legalizing euthanasia under strict conditions. In 2010, 3136 reports were made of euthanasia and assisted suicide; in 2014, 5306 reports were made. Among them were patients with a desire to donate their organs after their deaths...

Management strategies for dog populations and their diseases include reproductive control, euthanasia and vaccination, among others. However, the effectiveness of these strategies can be severely affected by human-mediated dog movement. If immigration is important, then the location of origin of dogs imported by humans will be fundamental to define the spatial scales over which population management and research should apply. In this context, the main objective of our study was to determine the spatial extent of dog demographic processes in rural areas and the proportion of dogs that could be labeled as immigrants at multiple spatial scales...

Despite several shortcomings, MS222 is the most commonly used chemical agent for euthanasia of zebrafish. Although lidocaine hydrochloride has some advantages over MS222, its effectiveness as a euthanasia agent for zebrafish is unknown. Larvae at 9 to 16 d postfertilization were exposed to 250 mg/L MS222 or 400, 500, 600, 700, 800, 900, or 1000 mg/L lidocaine and observed for cessation of heartbeat. Adult zebrafish were exposed to 250 mg/L MS222 or 400, 500, or 600 mg/L lidocaine; times to loss of righting reflex, cessation of opercular movement, and complete recovery; body length; aversive behavior; and gross and microscopic evidence of acute toxicity were evaluated...

Carbon dioxide is the most commonly used gas for euthanasia of rodents. The current AVMA Guidelines recommend slowly filling the container with CO2 (SF) and now indicate that the practice of placing conscious animals in containers prefilled with CO2 (PF) is unacceptable. An investigator noted pulmonary hemorrhage (PH) in BALB/c mice euthanized by SF that was not observed after PF. Here we evaluated whether the air-displacement rate (SF compared with PF) influenced the development of PH or nasal hemorrhage (NH) in 2 commonly used mouse strains...

Neutrophil-mediated inflammation was recently identified as an active contributor to athero-progression. Therapeutic strategies inhibiting neutrophil degranulation or recruitment were hypothesized to positively impact on plaque vulnerability. In this study, we investigated whether treatment with the recently discovered agonist of the Mas-related G-coupled receptor type D (MrgD) alamandine would impact on neutrophil degranulation in vivo and in vitro MATERIALS AND METHODS: Fifteen-week old ApoE-/- mice were fed with a Western-type diet for an additional 11 weeks...

The chicken eye was previously found to have little off-axis astigmatism which is not explained by its special corneal shape but rather by the optical properties of the crystalline lens. To learn more about lens design, we studied off-axis astigmatism in the chicken lens in situ and compared it to a glass lens of similar power but with homogenous refractive index. After euthanasia, enucleated eye balls were cut in the equatorial plane right behind the scleral ossicles. The anterior segment was placed in a water-filled chamber...

On February 2, 2016, the French government enacted the Claeys-Leonetti law introducing the right to deep and continuous sedation and forbade euthanasia for end-of-life patients. This article reports the first descriptions of this kind of intervention at the final stage of life of 3 patients and highlights the need of patient-centered goals and the importance of close collaboration between the patient, family, and medical and paramedical team to achieve a higher quality of final palliative care.

This study investigated whether or not prepubertal exposure to the fish contaminants methylmercury (MeHg) and the polychlorinated bisphenol Aroclor in low doses interferes with the histomorphometry of the testes, epididymis, liver and kidneys in rats. Wistar male rats, 21 days old, were allocated into the following: control (n = 17, received corn oil), MeHg (n = 17, received MeHg at 0.5 mg/kg/day), Aroclor (n = 17, received Aroclor at 1.0 mg/kg/day), low mix (n = 18, received MeHg at 0.05 mg/kg/day and Aroclor at 0...

The most important acute neurological diseases seen at neurosurgery departments are traumatic brain injuries (TBI) and subarachnoid hemorrhages (SAH). In both diseases the pathophysiological sequela are complex and have not been fully understood up to now, and rodent models using rats and mice are most suitable for the investigation of the pathophysiological details. In both models, surgery is performed under anesthesia, followed by assessment of their functional outcome and behavioral testing before brain tissue analysis after euthanasia...

This study compares different combinations of doses and routes of immunisation of pigs with low virulent African swine fever virus (ASFV) genotype I isolate OURT88/3, including the intramuscular and intranasal route, the latter not previously tested. Intranasal immunisations with low and moderate doses (10(3) and 10(4) TCID50) of OURT88/3 provided complete protection (100%) against challenge with virulent genotype I OURT88/1 isolate. Only mild and transient clinical reactions were observed in protected pigs...

Control of knee motion in small animal models is necessary to study the effect of mechanical load on the healing process. This can be especially challenging in mice, which are being increasingly used for various orthopedic reconstruction models. We explored the feasibility of botulinum toxin (Botox; Allergan, Dublin, Ireland) paralysis and a newly designed external fixator to restrict motion of the knee in mice undergoing anterior cruciate ligament (ACL) reconstruction. Nineteen C57BL/6 mice were allocated to two groups: (1) Botox group (n = 9) and (2) external fixator group (n = 10)...

The changes in thermal and mechanical hyperalgesia in paw cancer pain model mice and the action mechanism of toad skin extracts (TSE) was investigated. Eighty female mice were subcutaneously injected with saline or inoculated with H22 hepatoma cells in the right hind paw and administration with saline, vehicle, morphine and TSE. The pain behavior was recorded before treatment and at 0.5, 1.0, 1.5, 3 and 6h after initial administration, and thereafter on the 2nd, 4th, 6th, and 8th day after administration. On the last day, samples were collected after the euthanasia for the detection of β-END, CRF, IL-1β, POMC, μ-OR, CD3+, CD8+ and CD4+ in sera and the tumor tissues...

BACKGROUND: Even with recent scientific advancements, challenges posed by limited resources and capabilities at the time of sample dissection continue to limit the collection of high quality tissues from experiments that can be conducted only infrequently and at high cost, such as in space. The resources and time it takes to harvest tissues post-euthanasia, and the methods and duration of long duration storage, potentially have negative impacts on sample quantity and quality, thereby limiting the scientific outcome that can be achieved...

BACKGROUND: The practice of euthanasia and physicianassisted suicide has been compared between countries, but it has not been compared between regions within the Netherlands. This study assesses differences in the frequencies, characteristics, and trends of euthanasia and physician-assisted suicide between five regions in the Netherlands and tries to explain the differences by demographic, socioeconomic, and health-related differences between these regions. METHODS: Data on the frequencies, characteristics, and trends of euthanasia and physician-assisted suicide for each region and each year from 2002 through 2014 were derived from the annual reports of the Regional Review Committees...

INTRODUCTION: Radiation therapy (RT) is a major treatment modality, and the central nervous system is a dose-limiting organ in clinical RT. This experimental study aims to present the evaluation of the neuroprotective effects of erythropoietin (EPO) against oxidant injury following brain irradiation in rats. MATERIAL AND METHODS: Forty Wistar rats were randomly assigned to four groups (n = 10 each). In group 1 the rats received no EPO and underwent sham RT. The rats in groups 2 and 3 received EPO...

BACKGROUND: Reports about regulations and laws on Euthanasia and Physician Assisted Suicide (PAS) are becoming increasingly common in the media. Many groups have expressed opposition to euthanasia and PAS while those in favor argue that severely chronically ill and debilitated patients have a right to control the timing and manner of their death. Others argue that both PAS and euthanasia are ethically legitimate in rare and exceptional cases. Given that these discussions as well as the new and proposed laws and regulations may have a powerful impact on patients, caregivers, and health care providers, the International Association for Hospice and Palliative Care (IAHPC) has prepared this statement...

It is difficult to study bone in vitro because it contains various cell types that engage in cross-talk. Bone biologically links various organs, and it has thus become increasingly evident that skeletal physiology must be studied in an integrative manner in an intact animal. We developed a model using local intraosseous small interfering RNA (siRNA) injection to rapidly assess the effects of a target gene on the local skeletal environment. In this model, 160-g male Sprague-Dawley rats were treated for 1-2 weeks...

The infection caused by the zoonotic opportunistic pathogen Mycobacterium avium subsp. hominissuis (Mah) was reported for the first time in a pet ferret. Both owners were HIV-positive. Euthanasia of the pet was recommended due to medical reasons and as a preventive action. Disseminated and open tuberculosis lesions were observed in the gastrointestinal and respiratory systems of the ferret. Ecographic and radiographic surveys showed a severe generalized lymphadenopathy, strong thickening of the gastric wall and peritoneum layer...
