Saving and sacrificing: ethical questions in orangutan rehabilitation

The survival of wild orangutans, our close relatives and members of the great ape family, is increasingly threatened by anthropogenic activities, such as clearcutting for oil palm. In this context, orangutan mothers are often killed, and their infants turned into pets. If lucky, traumatised and sick orphans may be rescued by conservationists, who help the infant recover and gain survival skills (known as rehabilitation) before released back into the wild (reintroduction: together, R&R). Drawing on in-depth interviews with orangutan conservation and welfare workers, and visits to the majority of R&R projects in Indonesia and Malaysia, this thesis examines how ethical views shape how and why R&R is conducted. I propose that in a context of scarcity (of resources, time, space, and energy), efforts to “save” orangutans inevitably involve sacrifice: giving up something valuable, be it another orangutan or animal, an area of forest, or a value, such as orangutans’ welfare, wildness, or autonomy. Because practitioners do not always agree on what to prioritise, R&R remains controversial. For example, what if the orphan fails to learn how to be an orangutan again, after years in the company of humans? What if she is sent into the forest only to slowly starve? Would she have been better off in a cage, or is it better to give her “death with dignity” in the wild? Could the huge cost of sending a rescued ape back to the wild be better spent on stopping deforestation in the first place, thereby saving wild orangutans at the expense of the displaced? Or do we have a moral obligation to rescue the orphan regardless of cost? My research shows that ethical dilemmas lie at the heart of debates about whether it is better to release orphans into the wild, or keep them in captivity. Ethical conundrums are also at the heart of the often-heated debates about how R&R should be conducted. For example, while some allow released orangutans to “choose” whether to live alongside humans in a “semi-wild” state, others believe that true freedom can only be achieved by eliminating human contact. Further ethical dilemmas arise from decisions around whether to publicly criticise other groups’ methods, and how to secure funding without “greenwashing” or using images that portray orangutan orphans as “cute” rather than tragic. Deconstructing ethical positions is crucial for understanding the ongoing disagreements about how to help our endangered great ape kin. The current research is an effort to synthesise this discourse for conservation and R&R of the charismatic red ape

Edge cases in animal research law:Constituting the regulatory borderlands of the UK's animals (scientific procedures) act

This paper explores how the boundaries of the UK's Animals (Scientific Procedures) Act (A(SP)A) are constituted, as illustrative of the rising importance of legal procedures around animal research and how these are continuously being challenged and questioned. Drawing on empirical work in animal research communities, we consider how it is decided whether activities are undertaken for an “experimental or other scientific purpose”. We do this by focusing on “edge cases”, where debates occur about whether to include an activity within A(SP)A's remit. We demonstrate that the boundaries of animal research regulation in the UK are products of past and present decisions, dependencies, and social relationships. Boundaries are therefore not clear-cut and fixed, but rather flexible and changing borderlands. We particularly highlight the roles of: historical precedent; the management of risk, workload, and cost; institutional and professional identities; and research design in constituting A(SP)A's edges. In doing so, we demonstrate the importance of paying attention to how, in practice, animal law requires a careful balance between adhering to legal paragraphs and allowing for discretion. This in turn has real-world implications for what and how science is done, who does it, and how animals are used in its service

The New Zealand Kauri (Agathis Australis) Research Project: A Radiocarbon Dating Intercomparison of Younger Dryas Wood and Implications for IntCal13

We describe here the New Zealand kauri (Agathis australis) Younger Dryas (YD) research project, which aims to undertake Δ14C analysis of ~140 decadal floating wood samples spanning the time interval ~13.1–11.7 kyr cal BP. We report 14C intercomparison measurements being undertaken by the carbon dating laboratories at University of Waikato (Wk), University of California at Irvine (UCI), and University of Oxford (OxA). The Wk, UCI, and OxA laboratories show very good agreement with an interlaboratory comparison of 12 successive decadal kauri samples (average offsets from consensus values of –7 to +4 14C yr). A University of Waikato/University of Heidelberg (HD) intercomparison involving measurement of the YD-age Swiss larch tree Ollon505, shows a HD/Wk offset of ~10–20 14C yr (HD younger), and strong evidence that the positioning of the Ollon505 series is incorrect, with a recommendation that the 14C analyses be removed from the IntCal calibration database

Changes in neuromuscular structure and functions of human colon during ageing are region-dependent

Objective: To determine if human colonic neuromuscular functions decline with increasing age.Design: Looking for non-specific changes in neuromuscular function, a standard burst of electrical field stimulation (EFS) was used to evoke neuronally mediated (cholinergic/nitrergic) contractions/relaxations in ex vivomuscle strips of human ascending and descending colon, aged 35–91 years (macroscopically normal tissue; 239 patients undergoing cancer resection). Then, to understand mechanisms of change, numbers and phenotype of myenteric neurons (30 306 neurons stained with different markers), densities of intramuscular nerve fibres (51 patients in total) and pathways involved in functional changes were systematically investigated (by immunohistochemistry and use of pharmacological tools) in elderly (≥70 years) and adult (35–60 years) groups.Results: With increasing age, EFS was more likely to evoke muscle relaxation in ascending colon instead of contraction (linear regression: n=109, slope 0.49%±0.21%/year, 95% CI ), generally uninfluenced by comorbidity or use of medications. Similar changes were absent in descending colon. In the elderly, overall numbers of myenteric and neuronal nitric oxide synthaseimmunoreactive neurons and intramuscular nerve densities were unchanged in ascending and descending colon, compared with adults. In elderly ascending, not descending, colon numbers of cell bodies exhibiting choline acetyltransferase immunoreactivity increased compared with adults (5.0±0.6 vs 2.4±0.3 neurons/mm myenteric plexus, p=0.04). Cholinergically mediated contractions were smaller in elderly ascending colon compared with adults (2.1±0.4 and 4.1±1.1 g-tension/gtissue during EFS; n=25/14; p=0.04); there were no changes in nitrergic function or in ability of the muscle to contract/relax. Similar changes were absent in descending colon.Conclusion: In ascending not descending colon, ageing impairs cholinergic function

Astrocytes and Aging

By 2050, the aging population is predicted to expand by over 100%. Considering this rapid growth, and the additional strain it will place on healthcare resources because of age-related impairments, it is vital that researchers gain a deeper understanding of the cellular interactions that occur with normal aging. A variety of mammalian cell types have been shown to become compromised with age, each with a unique potential to contribute to disease formation in the aging body. Astrocytes represent the largest group of glial cells and are responsible for a variety of essential functions in the healthy central nervous system (CNS). Like other cell types, aging can cause a loss of normal function in astrocytes which reduces their ability to properly maintain a healthy CNS environment, negatively alters their interactions with neighboring cells, and contribute to the heightened inflammatory state characteristic of aging. The goal of this review article is to consolidate the knowledge and research to date regarding the role of astrocytes in aging. In specific, this review article will focus on the morphology and molecular profile of aged astrocytes, the consequence of astrocyte dysfunction on homeostatic functions during aging, and the role of astrocytes in age-related neurodegenerative diseases

Translation and cross-cultural adaptation of quality of life scale in patients with onychomycosis

(1) Background: Onychomycosis (OM) is a fungal nail infection, considered a risk factor for diabetic foot ulcers. It is associated with changes in quality of life, in terms of pain, self-confidence and self-esteem. The aim was to translate and adapt the OM quality of life questionnaire “OnyCOE-t™–Quality Of Life Questionnaire Onychomycosis (Nail Fungal Condition)”. (2) Methods: This study followed the guidelines proposed by Beaton et al. (2000), where two English to Portuguese translations were performed and, after an expert consensus, a common version was obtained. This was followed by two back-translations. The expert committee achieved semantic equivalence, idioms and concepts. The pre-test was applied to 49 people. The final version and processed data were sent to the authors. (3) Results: We adapted terms semantically, modified statements syntactically, altering items from interrogative to affirmative. (4) Conclusions: The translated version of the “Quality of life–Onychomycosis” questionnaire suggested that it can be used for further studies to test validity and reliability in this population.info:eu-repo/semantics/publishedVersio

The Universal Form of Treatment Options (UFTO) as an alternative to Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) orders: a mixed methods evaluation of the effects on clinical practice and patient care.

AIMS: To determine whether the introduction of the Universal Form of Treatment Options (the UFTO), as an alternative approach to Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) orders, reduces harms in patients in whom a decision not to attempt cardiopulmonary resuscitation (CPR) was made, and to understand the mechanism for any observed change. METHODS: A mixed-methods before-and-after study with contemporaneous case controls was conducted in an acute hospital. We examined DNACPR (103 patients with DNACPR orders in 530 admissions) and UFTO (118 decisions not to attempt resuscitation in 560 admissions) practice. The Global Trigger Tool was used to quantify harms. Qualitative interviews and observations were used to understand mechanisms and effects. RESULTS: RATE OF HARMS IN PATIENTS FOR WHOM THERE WAS A DOCUMENTED DECISION NOT TO ATTEMPT CPR WAS REDUCED: Rate difference per 1000 patient-days was 12.9 (95% CI: 2.6-23.2, p-value=0.01). There was a difference in the proportion of harms contributing to patient death in the two periods (23/71 in the DNACPR period to 4/44 in the UFTO period (95% CI 7.8-36.1, p-value=0.006). Significant differences were maintained after adjustment for known confounders. No significant change was seen on contemporaneous case control wards. Interviews with clinicians and observation of ward practice revealed the UFTO helped provide clarity of goals of care and reduced negative associations with resuscitation decisions. CONCLUSIONS: Introducing the UFTO was associated with a significant reduction in harmful events in patients in whom a decision not to attempt CPR had been made. Coupled with supportive qualitative evidence, this indicates the UFTO improved care for this vulnerable group.
