Radiographic morphology of canines tested for sexual dimorphism via convolutional-neural-network-based artificial intelligence.

The permanent left mandibular canines have been used for sexual dimorphism when human identification is necessary. Controversy remains whether the morphology of these teeth is actually useful to distinguish males and females. This study aimed to assess the sexual dimorphism of canines by means of a pioneering artificial intelligence approach to this end. A sample of 13,046 teeth radiographically registered from 5838 males and 7208 females between the ages of 6 and 22.99 years was collected. The images were annotated using Darwin V7 software. DenseNet121 was used and tested based on binary answers regarding the sex (male or female) of the individuals for 17 age categories of one year each (i.e. 6-6.99, 7.7.99… 22.22.99). Accuracy rates, receiver operating characteristic (ROC) curves and confusion matrices were used to quantify and express the artificial intelligence's classification performance. The accuracy rates across age categories were between 57-76% (mean: 68%±5%). The area under the curve (AUC) of the ROC analysis was between 0.58 and 0.77. The best performances were observed around the age of 12 years, while the worst were around the age of 7 years. The morphological analysis of canines for sex estimation should be restricted and allowed in practice only when other sources of dimorphic anatomic features are not available.

Short-term impact of air pollution, noise and temperature on emergency hospital admissions in Madrid (Spain) due to liver and gallbladder diseases.

BACKGROUND: Very few epidemiological studies have explored the environmental and meteorological risk factors that influence liver diseases and gallbladder disorders, and no studies have addressed the specific case of Spain. METHODS: This is a retrospective ecological study conducted during 2013-2018. We analysed emergency admissions in the central area of the Region of Madrid for the following causes: Liver and gallbladder diseases (L&GB) (ICD-10: K70-K81); disorders of gallbladder (DGB) (ICD 10: K80-K81); liver disease (LD) (ICD 10: K70-K77); alcoholic liver disease (ALD) (ICD-10: K70); viral hepatitis (VH) (ICD10:B15-B19); and hepatic failure, not elsewhere classified (HFNS) (ICD-10: K72). Independent variables used: meteorological (maximum daily temperature (Tmax in °C), minimum daily temperature (Tmin in °C), and relative humidity (RH in %)); chemical air pollution (8-hO3, NO2, PM10, PM2.5 in µg/m3); and noise pollution (equivalent level of daily noise (Ld in dB(A)). Transformed variables: extreme heat in degrees (Theat); wet cold (WC); and high ozone. We fitted Poisson models, negative binomials and zero-inflated Poisson controlled for seasonality, day of the week, holidays, trend, and autoregressive trend. Based on these models, the percentage of cases attributable to statistically significant risk factors was then estimated. RESULTS: In L&GB emergency admissions daily noise is related to 4.4% (CI95%: 0.8 7.9) of admissions; NO2 to 2.9% (CI95%: 0.1 5.7) and wet cold to 0.2% (CI95%: 0.8 7.9). Heat wave temperature was only related to ALD. In addition, the wet cold association with L&GB is also related to HFNS attributing 1.0% (CI95%: 0.3 1.8) of admissions for this cause. CONCLUSIONS: Daily noise and NO2 are associated with more than 7% of urgent L&GB admissions. Both pollutants, are mainly emitted by road traffic. A reduction of traffic in cities would result in a reduction of emergency admissions due to this cause.

Biopsia guiada por ecografía para el diagnóstico de masas ováricas. Revisión sistemática / Ecography guided biopsy for the diagnosis of ovarian masses. Systematic review

El diagnóstico definitivo del cáncer de ovario precisa de confirmación histológica. En determinadas situaciones, para evitar la morbilidad de la resección quirúrgica, es posible hacer una biopsia guiada por ecografía para obtener el diagnóstico anatomopatológico. El objetivo de esta revisión sistemática fue evaluar la adecuación, fiabilidad, precisión y perfil de seguridad de la biopsia guiada por ecografía de masas ováricas. Siguiendo el modelo PRISMA 2020, se hizo una búsqueda bibliográfica en PubMed, Embase y Scopus y se recopilaron un total de 10.245 artículos, de los cuales 24 fueron finalmente incluidos. Los trabajos incluían de forma mayoritaria pacientes con tumores inoperables avanzados, pobre performance status y otros factores de mal pronóstico, con masas de contenido sólido y márgenes irregulares, generalmente accesibles por vía transvaginal. En la mayoría de los artículos las pacientes presentaban historia previa de malignidad o tumores inoperables en estadios avanzados. Las masas ováricas biopsiables se definían en la ecografía como malignas o potencialmente malignas, con la presencia destacada de un componente sólido o mixto con márgenes irregulares o heterogéneos. La técnica más utilizada en los estudios incluidos fue la biopsia con aguja gruesa o tru-cut, con altos valores de adecuación, fiabilidad, precisión y rendimiento, así como un buen perfil de seguridad y bajas tasas de complicaciones. En conclusión, la biopsia con aguja gruesa de las masas anexiales guiada por ecografía, en pacientes subsidiarios de tratamiento neoadyuvante, es una técnica con altas tasas de adecuación, fiabilidad, precisión y buen perfil de seguridad.(AU)

The definitive diagnosis of ovarian cancer requires histological confirmation. In certain situations, to avoid the morbidity of surgical resection, it is possible to perform an ultrasound-guided biopsy to obtain the pathological diagnosis. The aim of this systematic review was to assess the adequacy, reliability, accuracy, and safety profile of ultrasound-guided biopsy of ovarian masses. Following the PRISMA 2020 model, a bibliographic search was carried out in PubMed, Embase and Scopus, collecting a total of 10,245 articles, of which 24 were finally included. The studies mainly included patients with advanced inoperable tumors, poor performance status and other poor prognostic factors, with masses of solid content and irregular margins, generally accessible through the transvaginal route. In most of the articles, the patients had a previous history of malignancy or had inoperable tumors in advanced stages. Biopsiable ovarian masses were defined ultrasonographically as malignant or potentially malignant, mainly highlighting the presence of a solid or mixed component and irregular or heterogeneous margins. The most widely used technique in the included studies was core needle or tru-cut biopsy, presenting high values of adequacy, reliability, precision and performance, as well as a good safety profile with low complication rates. In conclusion, ultrasound-guided core needle biopsy of adnexal masses in patients eligible for neoadjuvant treatment is a technique with high adequacy, reliability, and precision rates, as well as a good safety profile.(AU)

Short-term impact of extreme temperatures, relative humidity and air pollution on emergency hospital admissions due to kidney disease and kidney-related conditions in the Greater Madrid area (Spain).

While some studies report a possible association between heat waves and kidney disease and kidney-related conditions, there still is no consistent scientific consensus on the matter or on the role played by other variables, such as air pollution and relative humidity. Ecological retrospective time series study 01-01-2013 to 31-12-2018). Dependent variables: daily emergency hospitalisations due to kidney disease (KD), acute kidney injury (AKI), lithiasis (L), dysnatraemia (DY) and hypovolaemia (HPV). Independent variables: maximum and minimum daily temperature (Tmax, Tmin, °C), and daily relative humidity (RH, %). Other variables were also calculated, such as the daily temperature for risk of kidney disease (Theat, °C) and low daily hazardous relative humidity (HRH%). As variables of air pollution, we used the daily mean concentrations of PM10, PM2.5, NO2 and O3 in µg/m3. Based on these, we then calculated their daily excesses over World Health Organisation (WHO) guideline levels (hPM10, hPM2.5, hNO2 and hO3 respectively). Poisson family generalised linear models (GLMs) (link = log) were used to calculate relative risks (RRs), and attributable risks and attributable admissions. In the models, we controlled for the covariates included: seasonalities, trend, autoregressive component, day of the week, month and year. A statistically significant association was found between Theat and all the dependent variables analysed. The greatest AKI disease burden was attributable to Theat (2.2 % (1.7, 2.6) of attributable hospital admissions), followed by hNO2 (1.7 % (0.9, 3.4)) and HRH (0.8 (0.6, 1.1)). In the case of hypovolaemia and dysnatraemia, the greatest disease burden again corresponded to Theat, with 6.9 % (6.2, 7.6) and 5.7 (4.8, 6.6) of attributable hospital admissions respectively. Episodes of extreme heat exacerbate daily emergency hospital admissions due to kidney disease and kidney-related conditions; and attributable risks are likewise seen for low relative humidity and high ozone levels.

Exploratory analysis of local extreme-temperature attributable mortality in an urban city of Madrid.

AIM: to assess the Heat (HW) and Cold Waves (CW) risks on health in the urban municipality of Getafe. METHODOLOGY: time series analysis between 01/01/1999-31/10/2013. DEPENDENT VARIABLE: daily mortality due to natural causes - (ICD-10): A99-R99-. INDEPENDENT VARIABLES: the maximum (Tmax) and minimum (Tmin) daily temperature. The mortality-temperature relationship was analysed to determine the thresholds of HW (Thresholdheat) and CW (Thresholdcold). Using Poisson GLM (link = log), the Relative Risk (RR), Attributable Risk (AR) and Attributable Mortality (AM) were determined for each degree of the Tmax exceeding the Thresholdheat (Theat) and for each degree of Tmin under the Thresholdcold (Tcold). Finally, socioeconomic variables were analysed descriptively. RESULTS: Thresholdheat was 36 °C while Thresholdcold was 0 °C. The RRs associated with Theat, i.e. 1.08 (1.03 1.14), are akin to those obtained for Tcold, i.e. 1.05 (1.03 1.08). There were 202 HW and 430 CW episodes. The AM to HW totalled 61 (25, 96) deaths, while that attributable to CW reached 146 (82,211) deaths. The vulnerability in Getafe seems to be lower than in surrounding similar urban and rural cities. CONCLUSIONS: The singular urban development of the municipality may have granted it an advantage over surrounding municipalities regarding temperature extremes.

30 years of the ABFO study: Reproduction in a Brazilian sample.

The ABFO study on third molar development is a benchmark in the scientific literature of dental age estimation. In its 30th anniversary, the study has been reproduced in the present external validation. Standardized comparative outcomes were obtained and discussed across studies. The sample consisted of 1.087 panoramic radiographs of Brazilian females (n=542, 49.87%) and males (n=545, 50.13%) between 14 and 22.9 years. All available third molars were classified into developmental stages following Mincer's adaptation of Demirjian's system (8 sequential stages, from A to H). The mean chronological age of individuals within each stage was assessed. The probability of an individual being ≥ 18 years was calculated for each third molar, sex and stage. Maxillary and mandibular third molars showed a similar development with an agreement between stages of about 90%. In general, males developed 0.5 years (6 months) earlier than females. The probability of being an adult increased considerably when at least one third molar is in stage G. Maxillary third molars had higher coefficients of determination (right: 0.704; left: 0.702), showing that statistical models with these teeth could explain better the age estimation outcomes. The reproducibility of the ABFO study on third molar development led to reference tables and probability measures for the studied Brazilian population.

Short-term effects of tropospheric ozone and other environmental factors on emergency admissions due to pregnancy complications: A time-series analysis in the Madrid Region.

Air pollution has been linked to adverse neonatal outcomes, mainly in the case of prolonged exposures. This study focuses on the short-term effects on maternal health. We conducted a retrospective ecological time-series study in the Madrid Region covering the period 2013-2018. The independent variables were mean daily concentrations of tropospheric ozone (O3), particulate matter (PM10/PM2.5) and nitrogen dioxide (NO2), as well as noise levels. The dependent variables were daily emergency hospital admissions due to complications in pregnancy, childbirth and the puerperium. Poisson generalised linear regression models were fitted to quantify the relative and attributable risks, controlling for trend, seasonality, the autoregressive nature of the series, and a number of meteorological factors. There were 318 069 emergency hospital admissions due to obstetric complications across the 2191 days of study. Of this total: 13 164 (95%CI: 9930-16 398) admissions were attributable to exposure to O3, the only pollutant to show a statistically significant (p < 0.05) association with admissions due to hypertensive disorders; and 10 575 (95%CI: 3573-17 566) admissions were attributable to daytime noise levels, while admissions due to hyperemesis gravidarum and vomiting were related to exposure to night noise. Other pollutants which also displayed statistically significant associations were: NO2 concentrations, with admissions due to vomiting and preterm labour; PM10 concentrations, with premature rupture of membranes: and PM2.5 concentrations, with total complications. Exposure to a range of air pollutants, and ozone in particular, is associated with a higher number of emergency hospital admissions due to gestational complications. Hence, surveillance of environmental effects on maternal health should be intensified, and plans and strategies to minimise these should be drawn up.

Impact of urban heat islands on morbidity and mortality in heat waves: Observational time series analysis of Spain's five cities.

Urban heat islands (UHIs) have become an especially relevant phenomenon as a consequence of global warming and the growing proportion of people living in cities. The health impacts that are sometimes attributed to the rise in temperature generated in an UHI are not always adequately justified. The objective is to analyse what effect UHIs have on maximum (Tmax) and minimum daily temperatures (Tmin) recorded in urban and non-urban observatories, and quantify the impact on morbidity and mortality during heat waves in Spain's five cities. Data were collected on natural-cause daily mortality and unscheduled emergency hospital admissions (ICD-10: A00-R99) registered in these 5 cities across the period 2014-2018. We analysed daily Tmax and Tmin values at urban and non-urban observatories in these cities, and quantified the impact of Tmax and Tmin values during heat waves in each of these cities, using GLM models that included Tmax only, Tmin only, and both. We controlled for air pollution and other meteorological variables, as well as for seasonalities, trend and the autoregressive nature of the series. The UHI effect was observed in Tmin but not in Tmax, and proved to be greater in coastal cities than in inland and more densely populated cities. The UHI value in relation to the mean Tmin in the summer months ranged from 1.2 °C in Murcia to 4.1 °C in Valencia (difference between urban/non-urban observatories). The modelling process showed that, while a statistically significant association (p < 0.05) was observed in inland cities with Tmax for mortality and hospital admissions in heat waves, in coastal cities the association was obtained with Tmin, and the only impact in this case was the UHI effect on morbidity and mortality. No generalisations can be made about the impact of UHI on morbidity and mortality among the exposed population in cities. Studies on a local scale are called for, since it is local factors that determine whether the UHI effect will have a greater or lesser impact on health during heat-wave events.

How heat waves, ozone and sunlight hours affect endocrine and metabolic diseases emergency admissions? A case study in the region of Madrid (Spain).

BACKGROUND: Studies which analyse the joint effect of acoustic or chemical air pollution variables and different meteorological variables on neuroendocrine disease are practically nonexistent. This study therefore sought to analyse the impact of air pollutants and environmental meteorological variables on daily unscheduled admissions due to endocrine and metabolic diseases in the Madrid Region from January 01, 2013 to December 31, 2018. MATERIAL AND METHODS: We conducted a longitudinal, retrospective, ecological study of daily time series analysed by Poisson regression, with emergency neuroendocrine-disease admissions in the Madrid Region as the dependent variable. The independent variables were: mean daily concentrations of PM10, PM2.5, NO2 and O3; acoustic pollution; maximum and minimum daily temperatures; hours of sunlight; relative humidity; wind speed; and air pressure above sea level. Estimators of the statistically significant variables were used to calculate the relative risks (RRs). RESULTS: A statistically significant association was found between the increase in temperatures in heat waves, RR: 1.123 95% CI (1.001-1.018), and the number of emergency admissions, making it the main risk factor. An association between a decrease in sunlight and an increase in hospital admissions, RR: 1.005 95% CI (1.002 1.008), was likewise observed. Similarly, ozone, in the form of mean daily concentrations in excess of 44 µg/m3, had an impact on admissions due to neuroendocrine disease, RR: 1.010 95% CI (1.007-1.035). The breakdown by sex showed that in the case of women, NO2 was also a risk factor, RR: 1.021 95% CI (1.007-1.035). CONCLUSION: The results obtained in this study serve to identify risk factors for this disease, such as extreme temperatures in heat waves, O3 or NO2. The robust association found between the decrease in sunlight and increase in hospital admissions due to neuroendocrine disease serves to spotlight an environmental factor which has received scant attention in public health until now.

Palliative care management in patients with Parkinson's disease and other movement disorders in Spain. National survey of neurologists.

INTRODUCTION: Palliative care in neurodegenerative diseases is useful but underused. The objective of this study is to know how palliative care (PC) is applied in Spain in order to identify limitations and unmet needs. MATERIALS AND METHODS: It is a descriptive, observational, cross-sectional study, anonymous survey type of 20 questions, directed and answered by neurologists dedicated to movement disorders (MD) in Spain. RESULTS: 58 responses were obtained from neurologists from 15 autonomous communities. 69% answered that they did not have a specialised MD nursing facility but did have a PC team in their centre (81%). No specific protocol for PC in MD was identified. All except one neurologist stated that they lacked sufficient training in PC, the main training need being the "advance directives explanation". Only 1 in 4 neurologists answered routinely explaining advance healthcare planning to their patients, recognising up to 84.5% of neurologists not knowing how to assess the patient's competence. 60.3% of those surveyed answered that between 10% and 30% of their patients would be candidates for PC, although 1 in 3 said they were not clear when to refer the patient to PC. 100% of neurologists affirmed the priority need to implement PC protocols in MD. CONCLUSIONS: Our study shows a formative deficit in PC in this area and in the care of the patient with movement disorders and their environment, and should serve as a starting point to develop consensual care protocols.

Short-term impact of noise, other air pollutants and meteorological factors on emergency hospital mental health admissions in the Madrid region.

BACKGROUND: A number of environmental factors, such as air pollution, noise in urbanised settings and meteorological-type variables, may give rise to important effects on human health. In recent years, many studies have confirmed the relation between various mental disorders and these factors, with a possible impact on the increase in emergency hospital admissions due to these causes. The aim of this study was to analyse the impact of a range of environmental factors on daily emergency hospital admissions due to mental disorders in the Madrid Autonomous Region (MAR), across the period 2013-2018. METHODOLOGY: Longitudinal ecological time series study analysed by Generalised Linear Models with Poisson regression, with the dependent variable being daily Emergency Hospital Mental Health Admissions (EHMHA) in the MAR, and the independent variable being mean daily concentrations of chemical pollutants, noise levels and meteorological variables. RESULTS: EHMHA were related statistically significantly in the short term with diurnal noise levels. Relative risks (RRs) for total admissions due to mental disorders and self-inflicted injuries, in the case of diurnal noise was RR: 1.008 95%CI (1.003 1.013). Admissions attributable to diurnal noise account for 5.5% of total admissions across the study period. There was no association between hospital admissions and chemical air pollution. CONCLUSION: Noise is a variable that shows a statistically significant short-term association with EHMHA across all age groups in the MAR region. The results of this study may serve as a basis for drawing up public health guidelines and plans, which regard these variables as risk factors for mental disorders, especially in the case of noise, since this fundamentally depends on anthropogenic activities in highly urbanised areas with high levels of traffic density.

Percepción de utilidad entre profesionales sanitarios de un servicio de consultoría ética clínica / Healthcare workers’ perception of the usefulness of a healthcare ethics consultation service

Antecedentes y objetivo Los servicios de consultoría en ética clínica (CEC) surgen de los comités de ética para la asistencia sanitaria (CEAS) para atender conflictos éticos en tiempo real. Nuestro objetivo es conocer la percepción de utilidad de la CEC entre los profesionales sanitarios tras un año de su creación, así como evaluar los cambios de tendencia en el uso de la CEC y de los CEAS entre 2015 y 2021. Material y método Estudio observacional transversal mediante una encuesta estandarizada a los profesionales sanitarios de un hospital terciario urbano. Se compararon estos resultados con los de una encuesta idéntica realizada sobre la misma población en 2015. Resultados Participaron 213 profesionales (edad media 44 ± 11 años, 69% mujeres). Los profesionales conocían más la existencia de los CEAS que la CEC (94 vs. 61%; p<0,001). Un total de 45 encuestados (21%) habían consultado a la CEC desde su puesta en marcha; el 95% de ellos reconocían la utilidad de la consulta. Los facultativos conocían y utilizaban más la CEC que otros grupos profesionales. El grado de conocimiento sobre los CEAS en 2021 aumentó significativamente respecto a 2015 (94 vs. 76%; p<0,001). Se identificaron como áreas de mejora la necesidad de una mayor difusión del servicio, garantizar recursos institucionales para su mantenimiento y fomentar mayor participación de distintos profesionales. Conclusiones En los últimos años ha aumentado el conocimiento de los CEAS y de la CEC entre los profesionales sanitarios quienes consideran a la CEC útil para la atención de problemas éticos cotidianos (AU)

Background and objective Clinical ethics consultation services (CEC) have arisen from healthcare ethics committees (HEC) to address ethical conflicts in real-time. Our aim was to determine the perception of usefulness of a CEC service among healthcare workers one year after its creation as well as to assess changes in trends in the use of the CEC and HEC between 2015 and 2021. Material and method This observational, cross-sectional study was based on a standardized survey of healthcare workers at an urban tertiary care hospital. The results were also compared to those from an identical survey conducted in the same population in 2015. Results A total of 213 professionals participated (mean age 44±11 years, 69% women). The professionals were more familiar with the HEC than the CEC service (94 vs. 61%; p<0.001). Forty-five individuals (21%) had consulted the CEC since its implementation; 95% of them found the consultation useful. Physicians knew about and used the CEC more than other groups of professionals. The degree of knowledge of the HEC increased significantly by 2021 compared to 2015 (94 vs. 76%; p<0.001). Some areas for improvement identified were the need for greater dissemination of the service, guaranteeing institutional resources to maintain the service, and encouraging greater participation from different professional groups. Conclusions Knowledge of the institutional HEC and CEC services has increased in recent years among healthcare workers, who considered the CEC service to be useful for addressing ethical conflicts in daily practice (AU)

Does the meteorological origin of heat waves influence their impact on health? A 6-year morbidity and mortality study in Madrid (Spain).

BACKGROUND: In Spain, two synoptic-scale conditions influence heat wave formation. The first involves advection of warm and dry air masses carrying dust of Saharan origin (North African Dust (NAF) = 1). The second entails anticyclonic stagnation with high insolation and stability (NAF) = 0). Some studies show that the meteorological origin of these heat waves may affect their impact on morbidity and mortality. OBJECTIVE: To determine whether the impact of heat waves on health outcomes in Madrid (Spain) during 2013-2018 varied by synoptic-scale condition. METHODOLOGY: Outcome data consist of daily mortality and daily hospital emergency admissions (morbidity) for natural, circulatory, and respiratory causes. Predictors include daily maximum and minimum temperatures and daily mean concentrations of NO2, PM10, PM2.5, NO2, and O3. Analyses adjust for insolation, relative humidity, and wind speed. Generalized linear models were performed with Poisson link between the variables controlling for trend, seasonality, and auto-regression in the series. Relative Risks (RR) and Attributable Risks (AR) were determined. The RRs for mortality attributable to high temperatures were similar regardless of NAF status. For hospital admissions, however, the RRs for hot days with NAF = 0 are higher than for days with NAF = 1. We also found that atmospheric pollutants worsen morbidity and mortality, especially PM10 concentrations when NAF = 1 and O3 concentrations when NAF = 0. RESULTS: The effect of heat waves on morbidity and mortality depends on the synoptic situation. The impact is greater under anticyclonic stagnation conditions than under Saharan dust advection. Further, the health impact of pollutants such as PM10 and O3 varies according to the synoptic situation. CONCLUSIONS: Based on these findings, we strongly recommend prevention plans to include data on the meteorological situation originating the heat wave, on a synoptic-scale, as well as comprehensive preventive measures against the compounding effect of high temperatures and pollution.

Short-term effects of air pollution and noise on emergency hospital admissions in Madrid and economic assessment.

INTRODUCTION: The aim of this study was to study the effect of air pollution and noise has on the population in Madrid Community (MAR) in the period 2013-2018, and its economic impact. METHODS: Time series study analysing emergency hospital admissions in the MAR due to all causes (ICD-10: A00-R99), respiratory causes (ICD-10: J00-J99) and circulatory causes (ICD-10: I00-I99) across the period 2013-2018. The main independent variables were mean daily PM2.5, PM10, NO2, 8-h ozone concentrations, and noise. We controlled for meteorological variables, Public Holidays, seasonality, and the trend and autoregressive nature of the series, and fitted generalised linear models with a Poisson regression link to ascertain the relative risks and attributable risks. In addition, we made an economic assessment of these hospitalisations. RESULTS: The following associations were found: NO2 with admissions due to natural (RR: 1.007, 95% CI: 1.004-1.011) and respiratory causes (RR: 1.012, 95% CI: 1.005-1.019); 8-h ozone with admissions due to natural (RR: 1.049, 95% CI: 1.014-1.046) and circulatory causes (RR: 1.088, 95% CI: 1.039-1.140); and diurnal noise (LAeq7-23h) with admissions due to natural (RR: 1.001, 95% CI: 1.001-1.002), respiratory (RR: 1.002, 95% CI: 1.001-1.003) and circulatory causes (RR: 1.003, 95% CI: 1.002-1.005). Every year, a total of 8246 (95% CI: 4580-11,905) natural-cause admissions are attributable to NO2, with an estimated cost of close on €120 million and 5685 (95% CI: 2533-8835) attributed to LAeq7-23h with an estimated cost of close on €82 million. CONCLUSIONS: Nitrogen dioxide, ozone and noise are the main pollutants to which a large number of hospitalisations in the MAR are attributed, and are thus responsible for a marked deterioration in population health and high related economic impact.

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 24hours in 50 cases (79%). The department that consulted most often was the Intensive Care Unit (9; 14%).

Impact of the COVID-19 Pandemic on a Cancer Fast-Track Programme.

INTRODUCTION: The COVID-19 pandemic has disrupted many aspects of clinical practice in oncology, particularly regarding early cancer diagnosis, sparking public health concerns that possible delays could increase the proportion of patients diagnosed at advanced stages. In 2009, a cancer fast-track program (CFP) was implemented at the Clinico-Malvarrosa Health Department in Valencia, Spain with the aim of shortening waiting times between suspected cancer symptoms, diagnosis and therapy initiation. OBJECTIVES: The study aimed to explore the effects of the COVID-19 pandemic on our cancer diagnosis fast-track program. METHODS: The program workflow (patients included and time periods) was analysed from the beginning of the state of alarm on March 16th, 2020 until March 15th, 2021. Data was compared with data from the same period of time from the year before (2019). RESULTS: During the pandemic year, 975 suspected cancer cases were submitted to the CFP. The number of submissions only decreased during times of highest COVID-19 incidence and stricter lockdown, and overall, referrals were slightly higher than in the previous 2 years. Cancer diagnosis was confirmed in 197 (24.1%) cases, among which 33% were urological, 23% breast, 16% gastrointestinal and 9% lung cancer. The median time from referral to specialist appointment was 13 days and diagnosis was reached at a median of 18 days. In confirmed cancer cases, treatment was started at around 30 days from time of diagnosis. In total, 61% of cancer disease was detected at early stage, 20% at locally advanced stage, and 19% at advanced stage, displaying time frames and case proportions similar to pre-pandemic years. CONCLUSIONS: Our program has been able to maintain normal flow and efficacy despite the challenges of the current pandemic, and has proven a reliable tool to help primary care physicians referring suspected cancer patients.

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.

Different litter compositions influence broiler chicken locomotion.

Background: Bedding material must absorb moisture, reduce impacts, and allow chicken to express their natural behavior reducing the occurrence of injuries in the footpad and joints, and improving carcass quality and performance. Aims: This study evaluated different bedding materials with different levels of inclusion of dried grass (Zoysia japonica) on the development of lesions in the locomotor system of broiler chickens. Methods: One thousand eight-day-old male chicks of the Cobb 500® were distributed in a completely randomized design with a 3 × 2 factorial scheme: three levels of grass inclusion and two bedding materials (100% wood shavings; 100% rice husks; 25% grass and 75% wood shavings; 25% grass and 75% rice husks; 50% grass and 50% wood shavings; 50% grass and 50% rice husks). The birds at 21, 28, 35, and 42 days of age were evaluated for pododermatitis. Ten birds from each repetition were identified and evaluated weekly from 21 to 42 days for Gait score, latency to lie and leg angle (valgus and varus). At 43 days of age, 60 birds of each treatment were slaughtered and evaluated for femoral degeneration and tibial dyschondroplasia. Results: Different litter compositions did not affect the incidence of lameness, tibial dyschondroplasia and spondylolisthesis. Pododermatitis scores increased after 28 days when including 50% of grass. Conclusion: Age contributes more to the development of locomotion injuries than does bedding material. It is recommended to use inclusions of dried grass only as bedding for young broilers.

Gender differences in adaptation to heat in Spain (1983-2018).

In Spain the average temperature has increased by 1.7 °C since pre-industrial times. There has been an increase in heat waves both in terms of frequency and intensity, with a clear impact in terms of population health. The effect of heat waves on daily mortality presents important territorial differences. Gender also affects these impacts, as a determinant that conditions social inequalities in health. There is evidence that women may be more susceptible to extreme heat than men, although there are relatively few studies that analyze differences in the vulnerability and adaptation to heat by sex. This could be related to physiological causes. On the other hand, one of the indicators used to measure vulnerability to heat in a population and its adaptation is the minimum mortality temperature (MMT) and its temporal evolution. The aim of this study was to analyze the values of MMT in men and women and its temporal evolution during the 1983-2018 period in Spain's provinces. An ecological, longitudinal retrospective study was carried out of time series data, based on maximum daily temperature and daily mortality data corresponding to the study period. Using cubic and quadratic fits between daily mortality rates and the temperature, the minimum values of these functions were determined, which allowed for determining MMT values. Furthermore, we used an improved methodology that provided for the estimation of missing MMT values when polynomial fits were inexistent. This analysis was carried out for each year. Later, based on the annual values of MMT, a linear fit was carried out to determine the rate of evolution of MMT for men and for women at the province level. Average MMT for all of Spain's provinces was 29.4 °C in the case of men and 28.7 °C in the case of women. The MMT for men was greater than that of women in 86 percent of the total provinces analyzed, which indicates greater vulnerability among women. In terms of the rate of variation in MMT during the period analyzed, that of men was 0.39 °C/decade, compared to 0.53 °C/decade for women, indicating greater adaptation to heat among women, compared to men. The differences found between men and women were statistically significant. At the province level, the results show great heterogeneity. Studies carried out at the local level are needed to provide knowledge about those factors that can explain these differences at the province level, and to allow for incorporating a gender perspective in the implementation of measures for adaptation to high temperatures.
