Cadmium (Cd) and Lead (Pb) topsoil levels and incidence of childhood leukemias.

There are few well-established risk factors for childhood leukemias. While the frequency of childhood leukemias might be partially attributable to some diseases (accounting for a small fraction of cases) or ionizing radiation, the role of heavy metals has not been assessed. The objective of our study was to assess the potential association between levels of cadmium (Cd) and lead (PB) in soil and childhood leukemias incidence. We conducted a population-based case-control study of childhood leukaemia in Spain, covering 2897 incident cases gathered from the Spanish Registry of Childhood Tumours and including 14 Spanish Regions with a total population of 5,307,433 children (period 1996-2015). Cd and Pb bioavailable levels at every children's home address were estimated using data from the Geochemical Atlas of Spain. We used logistic regression to estimate odds ratios (ORs) and their 95% confidence intervals (95%CIs); we included as covariates: sex, rurality, employment rate and socioeconomic status. Metal levels were analysed according to two definitions: as continuous variable assuming linearity and as categorical variables to explore a potentially nonlinear association (quantiles). Increases in both Cd and Pb topsoil levels were associated with increased probability of childhood leukemias incidence. The results for the models with the continuous variables showed that a unit increase on the topsoil level was associated with an OR of 1.11 for Cd (95%CI 1.00-1.24) and an OR of 1.10 for Pb (95%CI 0.99-1.21). Our study may point towards a possible link between residential Cd and Pb topsoil levels and the probability of childhood leukemias incidence. Residing in a location with the highest concentrations of these heavy metals compared to those locations with the lowest could increase the risk around a 20%, for both Cd and Pb.

Environment, lifestyle behavior and health-related quality of life in childhood and adolescent cancer survivors of extracranial malignancies.

BACKGROUND: Childhood cancer is a chronic disease with high survival rates. Childhood cancer survivors (CCS) can still face health effects later in their lives. Health-related quality of life (HRQoL) and the factors that modify it allow CCS and their families to improve care in the long-term follow-up. This study aims to: (1) examine the differences in HRQoL between CCS of extracranial malignancies and a comparison group, and (2) explore the clinical, environmental and lifestyles factors implicated in the HRQoL of CCS. METHODS: In this cross-sectional study with a case vs. non-case comparison, the HRQoL of 117 CCS between 8 and 18 years old was compared with healthy non-cases paired by sex and age. The Pediatric Environmental History (PEHis) was applied to obtain information on sociodemographic, clinical, environmental and lifestyle factors. The PedsQL™ Generic Core Scales questionnaire was used to evaluate HRQoL. RESULTS: In the multivariate analysis among the CCS, the following variables were significantly associated with HRQoL: Poor outdoor air quality (Total, Psychosocial, Emotional, Social and School domains); household income (Total, Psychosocial and School domains); and the presence of late effects (Total, Physical, Psychosocial, and Social domains); regular contact with nature (Physical domain); and the daily hours of screen-time (Emotional domain). CCS present HRQoL results superior to the non-cases group in the physical domain (86.10 vs. 80.34; p=0.001), finding no differences in the other domains evaluated. CONCLUSIONS: An environmental and community health approach, such as PEHis, in CCS long-term programs promoting the creation of healthier environments and lifestyles contributes to improving their HRQoL and secondarily other chronic diseases.

Social distancing at health care centers early in the pandemic helps to protect population from COVID-19.

The impact of COVID-19 outbreak has been unequal across Spanish regions. The epidemic wave has been smoother in the Region of Murcia (RM) (6 deaths/100,000 residents). Physical distance from health centers from day 0 is an additional social distancing measure that confers an advantageous starting position in the fight against COVID-19. Late healthcare distancing measures are not as powerful as the early ones.

CONCLUSIONES: La contaminación atmosférica urbana aumenta los ingresos hospitalarios en pediatría por patología aguda respiratoria, especialmente por crisis de asma y bronquiolitis. Poner en marcha medidas preventivas, ampliar las series temporales y estudios colaborativos con datos en abierto ayudarían a mejorar la salud pública y la calidad del aire en las ciudades

INTRODUCTION: Urban air pollution is a major threat to child and adolescent health. Children are more vulnerable to its effects, being associated with higher morbidity and mortality due to acute and chronic diseases, especially respiratory ones. A study is performed on the relationship between urban air pollution and the rate of hospital admissions due to acute respiratory diseases. PATIENTS AND METHODS: An ecological study was conducted on young people under 17 years-old in the city of Murcia, who had visited hospital emergency departments due to respiratory diseases (ICD-9) during 2015. A logistic regression was performed on the risk of hospital admission that included consultations in relation to the average daily levels of environmental pollutants (NO2, O3, PM10, SO2) obtained from the Air Quality Surveillance and Control network of the Region of Murcia. Other control variables, such as gender, age, average daily ambient temperature, and season of the year. RESULTS: A total of 12,354 (56% boys and 44% girls) children consulted in the emergency department for respiratory disease. Of those, 3.5% were admitted, with a mean age of 2.54 (95% CI; 2.16-2.91) years. The odds ratio (OR) of hospital admission for respiratory diseases: NO2 1.02 (95% CI; 1.01-1.04; P <.01), O3 1.01 (95% CI; 1.00-1.03; P <.01) male 1.4 (95% CI 1.11-1.79; P <.01) and winter 2.10 (95% CI 1.40-3.21; P <.01). Admissions for asthma: PM10 1.02 (95% CI; 1.01-1.04; P <.05), O3 1.04 (95% CI; 1.01-1.06; P <.01). Admissions for bronchiolitis: Age 0.69 (95% CI; 0.48-0.99; P <.05); NO2 1.03 (95% CI; 1.01-1.05; P <.01). CONCLUSIONS: Urban air pollution increases hospital admissions in children due to acute respiratory diseases, especially asthma and bronchiolitis. Implementing preventive measures, expanding time series and collaborative studies with open data, would help improve public health and air quality in the cities

Secondhand smoke: A new and modifiable prognostic factor in childhood acute lymphoblastic leukemias.

BACKGROUND: The 5-year overall survival (OS) in childhood acute lymphoblastic leukemia (ALL) has reached 90% in high-income countries, levels that can no be longer overcome with strategies based on intensification of treatment. Other approaches in the search for new and modifiable prognostic factors are necessary to continue to improve these rates. The importance of environmental factors in the etiopathogenesis of childhood ALL has been regaining interest but its role in the prognosis and survival of this disease is not well explored. We aim to investigate the association between secondhand smoke (SHS) and survival in children diagnosed with ALL. METHODS: We analyzed survival rates in 146 patients under the age of 15 years diagnosed with ALL between January 1998 and May 2016 in the Region of Murcia, Spain. Evaluation of parental SHS and other known prognostic factors (sex, age, white blood cell count at diagnosis, cytogenetics, NCI/Rome Criteria, early response to therapy, and relapse) were assessed for impact on OS, event-free survival (EFS), cumulative incidence of relapse (CIR), and treatment-related mortality (CITRM) using Kaplan-Meier analysis, Cox regression, and Fine-Gray model. RESULTS: The mean follow-up time was 105.3 months (±66.5). Prenatal exposure to SHS due to parental smoking was highly prevalent. Of the mothers, 44.4% and 55.5% of the fathers smoked at some point during pregnancy. After the child's diagnosis of ALL 39.7% of mothers and 45.9% of fathers reported smoking. The Cox proportional hazards model showed that maternal smoking during pregnancy and after diagnosis (HR = 4.396, 95% CI: 1.173-16.474, p = 0.028); and relapse (HR = 7.919; 95% CI: 2.683-21.868; p < 0.001) are independent prognostic factors in determining survival. The Fine-Gray model showed that maternal smoking during pregnancy and after diagnosis (HR = 14.525, 95% CI: 4.228-49.90, p < 0.001) is an independent prognostic factor in CITRM. CONCLUSIONS: Persistent SHS worsens OS and TRM in children with ALL. This negative impact contributes to a different prognosis and may possibly provide an exceptional insight into new therapeutic approaches, including environmental aspects such as prevention and smoking cessation to improve survival outcomes.

Amenazas, desafíos y oportunidades para la salud medioambiental pediátrica en Europa, América Latina y el Caribe / Threats, challenges and opportunities for paediatric environmental health in Europe, Latin America and the Caribbean

En un mundo cada vez más tecnológico e interconectado, pero también más violento, esquilmado y contaminado, la salud medioambiental pediátrica (SMAP) constituye una de las mejores contribuciones para mejorar la salud global. Pocas zonas del planeta tienen una afinidad tan alta en valores e intereses como la Unión Europea (UE), América Latina y el Caribe (ALC). Las inversiones y actuaciones de la SMAP en periodos pre y posnatales durante las dos primeras décadas de vida generarán incontables beneficios en la salud y en el bienestar general en todas las épocas posteriores de la vida. Detectar, disminuir o eliminar los contaminantes físicos, químicos, biológicos y sociales es una de las principales misiones y acciones de la SMAP. En este artículo especial describimos, actualizamos y divulgamos las amenazas, los desafíos y las oportunidades de cooperación en la SMAP entre los profesionales biosanitarios y restantes sectores sociales implicados de la UE y de ALC. Surgen nuevos perfiles profesionales, estructuras de conocimiento y arquitecturas para el compromiso. Se requerirán liderazgos valientes, nuevos recursos sustanciales, amplios cambios sociales y la necesaria colaboración entre ambas regiones para mejorar la salud de las generaciones presentes y futuras

In a world that is increasingly technological and interconnected, but also more violent, overexploited and polluted, Paediatric Environmental Health (PEH) is one of the best contributions to improve global health. Few areas of the planet have a high affinity with common values and interests, such as the European Union (EU), Latin America and the Caribbean (LAC). The investments and actions of the PEH in pre- and postnatal periods during the first two decades of life will generate countless benefits in the health and well-being during the human life span. Detecting, reducing, or eliminating physical, chemical, biological and social pollutants is one of the main missions and actions of the PEH. In this special article, an update review is presented on the threats, challenges and cooperation opportunities in PEH among bio-health professionals and other social sectors involved, from the EU and LAC. New professional profiles, knowledge structures and architectures for engagement emerge. Courageous leaderships, new substantial resources, broad social changes, and the necessary collaboration between the two regions will be required to improve the health of present and future generations

Full Breastfeeding and Obesity in Children: A Prospective Study from Birth to 6 Years.

BACKGROUND: Obesity is a major public health crisis among both children and adults and contributes to significant physical, psychological, and economic burden. We aim to investigate the effect of duration of breastfeeding on excessive weight and obesity at 6 years of age. SUBJECTS/METHODS: Data on breastfeeding and child anthropometric measurements were collected in a birth-cohort study in Murcia, Spain (n = 350). Breastfeeding status and body mass index (BMI) were established according to WHO definitions. Other factors potentially related to children's weight were considered. Multiple log-linear and ordinal regressions were used to analyze the effects of breastfeeding on overweight and obesity when considering potential confounders. RESULTS: 33% and 17.3% of children in the study were of excess weight and obesity, respectively. Univariate predictors of BMI in children aged 6 were as follows: pregestational maternal BMI (kg/m2) (R2 = 0.127, p < 0.01); full breastfeeding (weeks) R2 = -0.035, p < 0.01); infant weight gain (kg) (R2 = 0.348, p < 0.01); and maternal alcohol consumption during pregnancy (g/day) (R2 = 0.266, p < 0.01) at age 6. In the ordinal logistic regression, full breastfeeding was associated with a significant decrease in obesity -0.052 (95% CI, -0.10 to -0.003). CONCLUSIONS: The delay of bottle feeding introduction may have a protective effect against obesity at 6 years of age. Our findings reinforce the need for greater support of breastfeeding and to promote a healthy environment and antipoverty interventions during pregnancy and infancy, alongside other strategies for obesity prevention.

Spatial clustering of childhood leukaemia with the integration of the Paediatric Environmental History.

BACKGROUND: Leukaemia remains the most common type of paediatric cancer and its aetiology remains unknown, but considered to be multifactorial. It is suggested that the initiation in utero by relevant exposures and/or inherited genetic variants and, other promotional postnatal exposures are probably required to develop leukaemia. This study aimed to map the incidence and analyse possible clusters in the geographical distribution of childhood acute leukaemia during the critical periods and to evaluate the factors that may be involved in the aetiology by conducting community and individual risk assessments. MATERIALS AND METHODS: We analysed all incident cases of acute childhood leukaemia (<15 years) diagnosed in a Spanish region during the period 1998-2013. At diagnosis, the addresses during pregnancy, early childhood and diagnosis were collected and codified to analyse the spatial distribution of acute leukaemia. Scan statistical test methodology was used for the identification of high-incidence spatial clusters. Once identified, individual and community risk assessments were conducted using the Paediatric Environmental History. RESULTS: A total of 158 cases of acute leukaemia were analysed. The crude rate for the period was 42.7 cases per million children. Among subtypes, acute lymphoblastic leukaemia had the highest incidence (31.9 per million children). A spatial cluster of acute lymphoblastic leukaemia was detected using the pregnancy address (p<0.05). The most common environmental risk factors related with the aetiology of acute lymphoblastic leukaemia, identified by the Paediatric Environmental History were: prenatal exposure to tobacco (75%) and alcohol (50%); residential and community exposure to pesticides (62.5%); prenatal or neonatal ionizing radiation (42.8%); and parental workplace exposure (37.5%) CONCLUSIONS: Our study suggests that environmental exposures in utero may be important in the development of childhood leukaemia. Due to the presence of high-incidence clusters using pregnancy address, it is necessary to introduce this address into the childhood cancer registers. The Paediatric Environmental History which includes pregnancy address and a careful and comprehensive evaluation of the environmental exposures will allow us to build the knowledge of the causes of childhood leukaemia.

Childhood cancer in small geographical areas and proximity to air-polluting industries.

AIM: Pediatric cancer has been associated with exposure to certain environmental carcinogens. The purpose of this work is to analyse the relationship between environmental pollution and pediatric cancer risk. METHOD: We analysed all incidences of pediatric cancer (<15) diagnosed in a Spanish region during the period 1998-2015. The place of residence of each patient and the exact geographical coordinates of main industrial facilities was codified in order to analyse the spatial distribution of cases of cancer in relation to industrial areas. Focal tests and focused Scan methodology were used for the identification of high-incidence-rate spatial clusters around the main industrial pollution foci. RESULTS: The crude rate for the period was 148.0 cases per 1,000,0000 children. The incidence of pediatric cancer increased significantly along the period of study. With respect to spatial distribution, results showed significant high incidence around some industrial pollution foci group and the Scan methodology identify spatial clustering. We observe a global major incidence of non Hodgkin lymphomas (NHL) considering all foci, and high incidence of Sympathetic Nervous System Tumour (SNST) around Energy and Electric and organic and inorganic chemical industries foci group. In the analysis foci to foci, the focused Scan test identifies several significant spatial clusters. Particularly, three significant clusters were identified: the first of SNST was around energy-generating chemical industries (2 cases versus the expected 0.26), another of NHL was around residue-valorisation plants (5 cases versus the expected 0.91) and finally one cluster of Hodgkin lymphoma around building materials (3 cases versus the expected 2.2) CONCLUSION: Results suggest a possible association between proximity to certain industries and pediatric cancer risk. More evidences are necessary before establishing the relationship between industrial pollution and pediatric cancer incidence.

Long term follow-up of a tobacco prevention and cessation program in cystic fibrosis patients. / Seguimiento a largo plazo de un programa de prevención y cesación tabáquica en pacientes con fibrosis quística.

This study evaluates the impact over time of a telephone-based intervention in tobacco cessation and prevention targeting patients with cystic fibrosis (CF) in the Mediterranean region of Murcia, Spain. We conducted an experimental prospective study with a cohort of CF patients using an integrative smoking cessation programme, between 2008 and 2013. The target population included family members and patients from the Regional CF unit. The study included an initial tobacco exposure questionnaire, measurement of lung function, urinary cotinine levels, anthropomorphic measures and the administered intervention at specific time intervals. Of the 88 patients tracked through follow-up, active smoking rates were reduced from 10.23% to 4.55% (p = 0.06). Environmental tobacco exposure was reduced in non-smoker patients from 62.03% to 36.90% (p < 0.01) during the five year follow-up. Significant reductions in the gradient of household tobacco smoke exposure were also observed with a decrease of 12.60%, from 31.65% (n = 25/79) to 19.05% (n = 16/84) in 2013 (p = <0.01). Cotinine was significantly correlated with both active and passive exposure (p<0.01) with a significant reduction of cotinine levels from 63.13 (28.58-97.69) to 20.56 (0.86-40.27) ng/ml (p<0.01). The intervention to significantly increase the likelihood of family quitting (smoke-free home) was 1.26 (1.05-1.54). Telephone based interventions for tobacco cessation and prevention is a useful tool when applied over time. Trained intervention professionals in this area are needed in the environmental health approach for the treatment of CF.

Estudio prospectivo experimental en una cohorte de pacientes con FQ utilizando un programa integrativo de cesación tabáquica, entre 2008 y 2013. La población diana incluye a pacientes y familiares de la unidad regional de FQ. El estudio incluyó un cuestionario inicial de exposición al tabaco, medición de la función pulmonar, niveles de cotinina en orina, medidas antropomórficas y la intervención realizada en intervalos de tiempo.De los 88 pacientes seguidos, la tasa de fumadores activos se redujo de 10,23% a 4,55% (p = 0,06). La exposición al humo ambiental de tabaco se redujo en los pacientes no fumadores de 62,03% a 36,90% (p < 0,01) durante los cinco años de seguimiento. Se observaron reducciones significativas en la exposición al humo ambiental de tabaco en los hogares, de 31,65% (n = 25/79) a 19,05% (n = 16/84) en 2013 (p = <0,01). La cotinina se correlacionó significativamente con la exposición al tabaco activa y pasiva (p < 0,01) con una reducción significativa de los niveles de cotinina de 63,13 (28,58-97,69) a 20,56 (0,86-40,27) ng/ml (p < 0,01). La intervención para aumentar significativamente la probabilidad de abandono familiar (hogar libre de humo) fue de 1,26 (1,05-1,54). La intervención telefónica mantenida en el tiempo es una herramienta útil para la prevención y cesación tabáquica. Profesionales entrenados en este modelo de intervención con enfoque en salud medioambiental son necesarios para mejorar el tratamiento de FQ.

Violence against women and gastroschisis: a case-control study.

BACKGROUND: Gastroschisis, a birth defect characterized by herniated fetal abdominal wall, occurs more commonly in infants born to teenage and young mothers. Ischemia of the vascular vitelline vessels is the likely mechanism of pathogenesis. Given that chronic stress and violence against women are risk factors for cardiovascular disease we explored whether these may represent risk factors for gastroschisis, when they occur during pregnancy. A case-control study was conducted, with 15 incident cases of children born with gastroschisis in the Region of Murcia, Spain, from December 2007 to June 2013. Forty concurrent controls were recruited at gestation weeks 20-24 or post-partum. All mothers of cases and controls completed a comprehensive, in-person, 'green sheet' questionnaire on environmental exposures. RESULTS: Mothers of children with gastroschisis were younger, smoked more cigarettes per week relative to controls, were exposed to higher amounts of illegal drugs, and suffered from domestic violence more frequently than the controls. Multivariable logistic regression analysis highlights periconceptional 'gender-related violence' (OR: 16.6, 95% CI 2.7 to 101.7) and younger maternal age (OR 1.1, 95% CI 1.0-1.3). CONCLUSIONS: Violence against pregnant women is associated with birth defects, and should be studied in more depth as a cause-effect teratogenic. Psychosocial risk factors, including gender-based violence, are important for insuring the health and safety of the pregnant mother and the fetus.
