Introducción La consultoría en ética clínica (CEC) es un modelo útil de asesoría ética, pero con escasa implantación en Europa. En el presente artículo se comparte la experiencia de uno de los primeros servicios de consultoría ética en España. Material y métodos Estudio observacional retrospectivo de todas las consultas recibidas por el servicio de CEC del Hospital Universitario de La Princesa (Madrid, España) entre el 1 de septiembre de 2019 y el 31 de agosto de 2021. Se analizaron variables demográficas, logísticas y éticas de los casos. Resultados Se analizaron 63 casos, en los que se identificaron un total de 124 conflictos éticos. El 41% (n=26) de las consultas eran de carácter urgente y el 38% (n=24), preferentes. La evaluación inicial se realizó en menos de 24horas en 50 casos (79%).

Description of the experience of a clinical ethics consultation service from 2019 to 2021.

INTRODUCTION: Clinical ethics consultation services (CEC) are useful model for ethical counselling, albeit with scarce implementation in European countries. This article shares the experience of one of the first ethics consultation services in Spain. MATERIALS AND METHODS: This work is a retrospective, observational study of all consultations received by the CEC service at La Princesa University Hospital (Madrid, Spain) from September 1, 2019 to August 31, 2021. The demographic, logistic, and ethical variables of the cases were analyzed. RESULTS: A total of 63 cases were analyzed in which a total of 124 ethical conflicts were identified. Forty-one percent of the cases (n = 26) were emergency consultations and 38% (n = 24) were preferential inquiries. An initial evaluation was performed with 24 h in 50 cases (79%). The department that consulted most often was the Intensive Care Unit (9; 14%). The preferred contact methods were via pager (36; 57%), the electronic medical record system (13; 21%), or direct conversations with consulting team (7; 11%). The most common ethical conflicts were those related to the adequacy of treatment measures (24; 19%), refusal of treatment (19; 15%), communication with the patient or his/her family (29; 23%), or the patient's capacity (13; 11%). CONCLUSION: CEC services provide quick, efficient assistance for resolving ethical problems in daily practice. Their implementation in Spain is feasible.

Boron exposure assessment using drinking water and urine in the North of Chile.

Boron is an essential trace element for plants and humans however it is still an open question what levels of boron are actually safe for humans. This study, conducted between 2006 and 2010, measured exposure levels of boron in drinking water and urine of volunteers in Arica, an area in the North of Chile with high levels of naturally occurring boron. Samples were taken of tap and bottled water (173 and 22, respectively), as well as urine from 22 volunteers, and subsequently analyzed by inductively coupled plasma spectroscopy (ICP-OES). Boron varied in public tap water from 0.22 to 11.3mgL(-1), with a median value of 2.9mgL(-1), while concentrations of boron in bottled water varied from 0.01 to 12.2mgL(-1). Neither tap nor bottled water samples had concentrations of boron within WHO recommended limits. The concentration of boron in urine varied between 0.45 and 17.4mgL(-1), with a median of 4.28mgL(-1) and was found to be correlated with tap water sampled from the homes of the volunteers (r=0.64). Authors highly recommend that in northern Chile - where levels of boron are naturally high - that the tap and bottled water supplies be monitored in order to protect public health and that regulatory standards also be established for boron in drinking water in order to limit exposure.

Lung cancer and arsenic concentrations in drinking water in Chile.

Cities in northern Chile had arsenic concentrations of 860 microg/liter in drinking water in the period 1958-1970. Concentrations have since been reduced to 40 microg/liter. We investigated the relation between lung cancer and arsenic in drinking water in northern Chile in a case-control study involving patients diagnosed with lung cancer between 1994 and 1996 and frequency-matched hospital controls. The study identified 152 lung cancer cases and 419 controls. Participants were interviewed regarding drinking water sources, cigarette smoking, and other variables. Logistic regression analysis revealed a clear trend in lung cancer odds ratios and 95% confidence intervals (CIs) with increasing concentration of arsenic in drinking water, as follows: 1, 1.6 (95% CI = 0.5-5.3), 3.9 (95% CI = 1.2-12.3), 5.2 (95% CI = 2.3-11.7), and 8.9 (95% CI = 4.0-19.6), for arsenic concentrations ranging from less than 10 microg/liter to a 65-year average concentration of 200-400 microg/liter. There was evidence of synergy between cigarette smoking and ingestion of arsenic in drinking water; the odds ratio for lung cancer was 32.0 (95% CI = 7.2-198.0) among smokers exposed to more than 200 microg/liter of arsenic in drinking water (lifetime average) compared with nonsmokers exposed to less than 50 microg/liter. This study provides strong evidence that ingestion of inorganic arsenic is associated with human lung cancer.

Lung cancer and arsenic exposure in drinking water: a case-control study in northern Chile.

In some Chilean cities, levels of arsenic (As) in drinking water reached 800 (micrograms/L between 1950 and 1970, while current levels are 40 (micrograms/L. To evaluate the causal role of this exposure in lung and bladder cancers, we conducted a case-control study in Regions I, II, and III of the country. From 1994 to 1996, cases diagnosed as lung cancer and two hospital controls were entered in the study; one control was a patient with a cancer, while the other was a patient without cancer, both conditions unrelated to As. Controls were matched with cases by age and sex. A standard survey containing questions about residence, employment, health history, was administered to study subjects. Data on As concentrations in water were obtained from records of the municipal water companies. A total of 151 lung cancer cases and 419 controls (167 with cancer and 242 without cancer) were enrolled. Median level of lifetime As exposure was significantly higher among cases, with a clear dose-response relationship between mean As exposure levels, with an OR (95% CI) of: 1, 1.7 (0.5-5.1), 3.9 (1.2-13.4), 5.5 (2.2-13.5), and 9.0 (3.6-22) for strata one to five respectively. This study provides new evidence that As in drinking water can cause internal cancers and gives an estimate of the form of this relationship.
