- Aim: To examine how physicians' life stances affect their attitudes to end-of-life decisions and their actual end-of-life decision-making. Methods: Practising physicians from various specialties involved in the care of dying patients in Belgium, Denmark, The Netherlands, Sweden, Switzerland and Australia received structured questionnaires on end-of-life care, which included questions about their life stance. Response rates ranged from 53% in Australia to 68% in Denmark. General attitudes, intended behaviour with respect to two hypothetical patients, and actual behaviour were compared between all large life-stance groups in each country. Results: Only small differences in life stance were found in all countries in general attitudes and intended and actual behaviour with regard to various end-of-life decisions. However, with regard to the administration of drugs explicitly intended to hasten the patient's death (PAD), physicians with specific religious affiliations had significantly less accepting attitudes, and less willingness to perform it, than non-religious physicians. They had also actually performed PAD less often. However, in most countries, both Catholics (up to 15.7% in The Netherlands) and Protestants (up to 20.4% in The Netherlands) reported ever having made such a decision. Discussion: The results suggest that religious teachings influence to some extent end-of-life decision-making, but are certainly not blankly accepted by physicians, especially when dealing with real patients and circumstances. Physicians seem to embrace religious belief in a non-imperative way, allowing adaptation to particular situations.

- This study examined the proportion of deaths taking place in hospitals in six European countries in relation to demographic, epidemiologic and healthcare factors. Retrospective analyses were performed on a database integrating death certificate data of all deaths in 2002 in Sweden and 2003 in Belgium, England, Scotland, the Netherlands and Wales (N = 891,780). Data were linked with regional healthcare statistics. Of all deaths, from 33.9% (the Netherlands) to 62.8% (Wales) occurred in hospital. Large country differences in hospital deaths were partly explained by the availability of care home and hospital beds. Differences between countries were strikingly large in older patients and cancer patients. Older patients had a higher probability of dying in hospital in Sweden, Scotland, England and Wales than in Flanders and, in particular, in the Netherlands. Cancer patients often died in hospitals in Sweden but less frequently so in the Netherlands and England. Country differences in the proportion of patients dying in hospital are only partly the result of differences in health care provision, and are in particular larger for certain patient categories, suggesting country-specific end-of-life practices in these categories. These findings can contribute to rational public health policies aimed at reducing hospital deaths.

- Background: Modern medicine provides unprecedented opportunities in diagnostics and treatment. However, in some situations at the end of a patient's life, many physicians refrain from using all possible measures to prolong life. We studied the incidence of different types of treatment withheld or withdrawn in 6 European countries and analyzed the main background characteristics. Methods: Between June 2001 and February 2002, samples were obtained from deaths reported to registries in Belgium, Denmark, Italy, the Netherlands, Sweden, and Switzerland. The reporting physician was then sent a questionnaire about the medical decision-making process that preceded the patient's death. Results: The incidence of nontreatment decisions, whether or not combined with other end-of-life decisions, varied widely from 6% of all deaths studied in Italy to 41% in Switzerland. Most frequently forgone in every country were hydration or nutrition and medication, together representing between 62% (Belgium) and 71% (Italy) of all treatments withheld or withdrawn. Forgoing treatment estimated to prolong life for more than I month was more common in the Netherlands (10%), Belgium (9%), and Switzerland (8%) than in Denmark (5%), Italy (3%), and Sweden (2%). Relevant determinants of treatment being withheld rather than withdrawn were older age (odds ratio [OR], 1.53; 95% confidence interval [CI], 1.31-1.79), death outside the hospital (death in hospital: OR, 0.80; 95% CI, 0.68-0.93), and greater lifeshortening effect (OR, 1.75; 95% Cl, 1.27-2.39). Conclusions: In all of the participating countries, life prolonging treatment is withheld or withdrawn at the end of life. Frequencies vary greatly among countries. Low technology interventions, such as medication or hydration or nutrition, are most frequently forgone. in older patients and outside the hospital, physicians prefer not to initiate life-prolonging treatment at all rather than stop it later.

- Whether or not artificial nutrition or hydration (ANH) may be forgone in terminally ill patients has been the subject of medical and ethical discussions. Information about the frequency and background characteristics of making decisions to forgo ANH is generally limited to specific clinical settings. The aim of this study was to compare the Practice of forgoing ANH in six European countries: Belgium, Denmark, Italy, The Netherlands, Sweden, and Switzerland. In each country, random samples were drawn from death registries. Subsequently, the reporting physician received a questionnaire about the medical decisions that preceded the patient's death. The total number of deaths studied was 20,480. The percentage of all deaths that were preceded by a decision to forgo ANH varied from 2.6% in Italy to 10.9% in The Netherlands. In most countries, decisions to forgo ANH were more frequently made for female patients, patients aged 80 years or older, and for patients who died of a malignancy or disease of the nervous system (including dementia). Of patients in whom ANH was forgone, 67%-93% were incompetent. Patients in whom ANH was forgone did not receive more potentially life-shorlening drugs to relieve symptoms than other Patients for whom other end-of-life decisions had been made. Decisions to forgo ANH are made in a substantial percentage of terminally ill patients. Providing all patients who are in the terminal stage of a lethal disease with ANH does not seem to be a widely accepted standard among physicians in Western Europe.

- Volatile fatty acids (VFAs) produced during anaerobic digestion (AD) of organic waste are a promising alternative carbon source for various biological processes; however, their applications are limited due to the presence of impurities such as ammonium (NH4+). This study investigates the potential for removal of ammonium using a naturally occurring zeolite (clinoptilolite) from chicken manure (CKM) derived VFA effluent recovered from an anaerobic membrane bioreactor (MBR). Experiments were conducted for both synthetic and actual VFA (AD-VFA) solutions, and the effects of different parameters were investigated with batch and continuous studies. It was observed that the Langmuir-type isotherm provided the best fit to the equilibrium data in the isotherm investigations carried out with the AD-VFA solution. The maximum adsorption capacity (qm) was found as 15.7 mg NH4+/g clinoptilolite. The effect of some operational parameters on process performance such as pH, initial NH4+ loading and potassium ion (K+) concentration was investigated. The pH had a negligible effect on ammonium removal for a pH range of 3–7, while the removal efficiency of ammonium decreased with the increase of initial NH4+ loading and K+ concentration. At the optimum conditions determined in batch experiments, the ammonium removal from synthetic and AD-VFA solutions were compared and average ammonium removal efficiencies of 93 and 94% were found in 12 h equilibrium time for synthetic and AD-VFA solutions, respectively. Overall findings indicated that clinoptilolite has excellent potential for ion exchange when combined with biological processes such as acidogenic fermentation of VFAs to purify the solution from high-ammonium content.
