Texto completoEl impacto humano sobre los recursos hídricos que forman los acuíferos es actualmente una de las grandes preocupaciones sociales en crecimiento debido a la presencia antrópica cada vez mayor de productos químicos tóxicos liberados en el subsuelo. El análisis de riesgo proporciona la herramienta científica necesaria para cuantificar el peligro real que estos contaminantes suponen para la salud humana. En concreto, el análisis de riesgo permite tomar decisiones que respondan a las siguientes preguntas: Qué puede pasar?. Qué tan probable es que suceda? Cuál pueden ser las consecuencias?. El análisis de riesgo es una herramienta clave en este sentido. Sin embargo, los esfuerzos de modelación necesarios para llevar a cabo el análisis de riesgo se enfrentan con varios problemas. Entre ellos, algunos productos tóxicos de degradación pueden constituir nuevos compuestos químicos nocivos no necesariamente menos tóxico que su producto padre. Por lo tanto, los contaminantes originales y sus productos hijos son susceptibles de coexistir en los acuíferos formando una mezcla de compuestos químicos de diferente toxicidad. Esto hace que la cuantificación e interpretación del riesgo para la salud humana sea una tarea no trivial y desafiante. Por otra parte, la falta de informaci´on en las propiedades hidráulicas y bioquímicos hace que las predicciones sobre el comportamiento de dichos contaminantes en el subsuelo sean altamente inciertas. El análisis de riesgo estocástico incorpora de forma natural la incertidumbre hidrogeológica que existe en las predicciones de riesgo para la salud humana. De esta manera, estos modelos pueden ser utilizados para determinar la probabilidad de que el riesgo supere un valor umbral o el valor esperado del riesgo y su incertidumbre. Desafortunadamente, estos enfoques son muy exigentes en tiempo de cálculo. Además de estas dos problemáticas, también se tiene que tener en cuenta que la composición mineralógica de un suelo real es diversa y variable en el espacio. Muchas veces esto implica la transferencia de masa entre zonas de contaminantes móviles e inmóviles. Esto último exige modelos sofisticados de transporte que, por ejemplo, conceptualicen el medio poroso como un sistema multi-porosidad. Finalmente, la complejidad que existe en el comportamiento del foco de contaminación hace complicado un análisis de riesgo. Los líquidos tóxicos densos y no acuosos ilustran perfectamente esta complejidad. Una vez en el subsuelo, estos líquidos liberación lentamente los contaminantes dentro del acuífero de acuerdo con una tasa de agotamiento que depende fuertemente de la arquitectura errática del foco de contaminación. Los modelos de transporte reactivo eulerianos tienen problemas numéricos cuando se simulan fuertes heterogeneidades hidro-bioquímicos en el terreno al mismo tiempo que reacciones químicas complejas en sistemas multi-porosidad. En este contexto, los métodos de trayectorias de partículas constituyen una alternativa viable. Sin embargo, estos métodos pueden tener en cuenta un rango pequeño de reacciones químicas. El trabajo presentado en esta tesis propone una solución a estos problemas mediante un método de trayectoria de partículas. El método es eficiente y capaz de simular cadenas y redes de degradación en sistemas heterogéneos con porosidad múltiples. El método se basa en el desarrollo de probabilidades de transición que describen las probabilidades de que las partículas que pertenecen a un estado determinado (producto químico y región móvil / inmóvil) en un momento dado se transformará en otro estado en un momento posterior. El método se utiliza para caracterizar el riesgo para la salud humana que representan las mezclas de degradación en medios porosos altamente heterogéneos derivados de focos de contaminación complejos. En particular, se investiga la interacción entre la heterogeneidad, la conectividad, el modo de inyección de los contaminantes y su toxicidad química con respecto a la caracterización probabilística del riesgo para la salud humana. Los resultados indican las condiciones mediante las cuales las vías de flujo preferencial pueden favorecer la reducción del riesgo para la salud humana. La dependencia de la conectividad con el riego se demuestra que no es nada trivial cuando se trata de mezclas de compuestos químicos. Esta no trivialidad es el resultado de la interacción entre la heterogeneidad del acuífero y la toxicidad de los compuestos químicos. Para cuantificar el efecto conjunto de la conectividad y la toxicidad en el riesgo para la salud, se propone un número de Damköhler nuevo que tiene en cuenta la toxicidad. Además, el riesgo también se caracteriza en términos estadísticos mediante momentos de bajo orden y funciones de densidad de probabilidad. Los resultados también muestran que tanto la capacidad de degradación de zonas inmóviles como los modelos existentes de agotamiento del foco pueden desempeñar un papel muy significativo en el análisis espacio-temporal del riesgo. Este trabajo también muestra que la eficiencia del foco de contaminación para concentrar el flujo puede tener un efecto beneficioso sobre el riesgo. El riesgo total de hecho tiende a disminuir para eficiencias grandes debido a la disminución consecuente en tiempos de viaje cerca del foco de contaminación, limitando la producción de productos de degradación más tóxicos.

Texto completoData were collected during a prospective cohort study conducted in Brazil. Incidence density rates of infection were calculated and determinants of incident infection were identified using Cox regression models. Analyses were done for HPV types classified into low-risk and high-risk depending on their association with cervical neoplasia.
The incidence density rates were 9.3 and 7.6 per 1000 women-months respectively for low-risk and high-risk HPV infection. Independent positive associations were found between the time of first occurrence of low-risk infection and age, number of sexual partners in the past 5 years, education level and use of non-commercial hygienic absorbents. The first occurrence of high-risk infection was independently predicted by age, age at first sexual intercourse, condom use (negative associations) and by the number of sexual partners in the past year (positive association). Elucidation of the dynamics of infection is a first step towards implementation of public health programs for reducing the risk of cervical cancer.

Texto completoENGLISH ABSTRACT: Background: The rising prevalence of non-communicable diseases (NCD) is cause for concern. Improving dietary quality is a key health promotion strategy aimed at reducing NCD morbidity and mortality. Assessments that quantify “risky” dietary behaviours are worthwhile, and may help to identify high risk individuals, that would benefit from targeted interventions. Purpose: Discovery Vitality is a wellness incentive business associated with Discovery Health medical aid in South Africa. This study developed a Dietary Behaviour Score (DBSPHR) that measured degrees of compliance of Discovery Vitality members with the “spirit of dietary guidance”. It further categorized scores and identified members who may be at risk for developing NCDs due to poor dietary compliance. Methods: The DBSPHR included proportionally weighted components related to the consumption of fruit, vegetables, low fat dairy, whole-grain foods, lean meat, chicken and discretionary fat. The study population included adult South African members of Discovery Vitality, who had completed the programme’s on-line health risk assessment (PHR) between the 1st February 2010 and 31st January 2011. Stratified random sampling was used (n=1600). Half the sample included members who participated in Vitality’s HealthyFoodTM benefit (HFB) programme. The different Vitality Status groups were equally represented, and reflect degrees of engagement with the programme. Genders were equally represented. DBSPHR data were categorized as: Poor (Score 0-18), Inadequate (18.5-22.5), Fair (23-26), Good (26.5-29), Excellent (29.5-36). DBSPHR data was analyzed for variables: Vitality status, HFB participation, smoking, physical activity, alcohol consumption, body mass index (BMI), age and gender. The relationships between continuous response variables and nominal input variables were analysed using analysis of variance (ANOVA). When ordinal response variables were compared versus a nominal input variable, non-parametric ANOVA methods were used. Further, the Mann-Whitney test or the Kruskal-Wallis test was used. A p-value of p < 0.05 was considered to represent statistical significance, and 95% confidence intervals were used to describe the estimation of unknown parameters. Results: Of the sample, 67.13% of members had DBSPHRs that were considered “poor” or “inadequate”. The mean DBSPHR of the sample was 20.47 points. Women achieved better DBSPHRs than men (p<0.01). Greater engagement with the Vitality programme was associated with better DBSPHRs (p<0.01). There was no significant difference between the mean DBSPHR of members participating in the HFB and Non-HFB members, however the HFB was not assessed as an intervention. Members with “risky” lifestyle behaviours such as; inactivity, smoking and consuming alcohol excessively, demonstrated lower DBSPHR than members without these risks. Obese members achieved significantly lower DBSPHRs than normal weight and overweight members (p<0.01). Conclusions: It is concerning that Discovery Vitality members did not perform better than the general global standard of inadequate compliance with the “spirit of dietary guidance”. Engagement with the Vitality programme seems to positively impact on dietary compliance. Members at an increased risk for NCD morbidity and mortality due to; aging, obesity, smoking, inactivity or non-compliance with alcohol consumption guidelines, demonstrated lower DBSPHRs compared to members without these risks. Targeted interventions aimed at addressing “risky” dietary and lifestyle behaviours may benefit these members.
AFRIKAANSE OPSOMMING: Agtergrond: Die styging in voorkoms van nie-oordraagbare siektes (NOS) is rede tot kommer. Verbetering van dieetkwaliteit is ‘n sleutel gesondheidsbevordering strategie gemik daarop om NOS morbiditeit en mortaliteit te verminder. Assesserings wat “riskante” dieetgedrag kwantifiseer is waardevol en mag help om hoë risiko individue te identifiseer wat sal baatvind by geteikende intervensies. Doel: Discovery Vitality is ‘n welwees motiveringsbesigheid wat geassosieer is met Discovery Health mediese fonds in Suid-Afrika. Hierdie studie het ‘n dieet-gedragstelling (“Dietary Behaviour Score - DBSPHR”) ontwikkel wat die graad van nakoming van Discovery Vitality lede gemeet het aan die “gees van leiding oor dieet”. Dit het verder tellings gekategoriseer en lede geïdentifiseer wat ‘n verhoogde risiko vir die ontwikkeling van NOS mag hê as gevolg van swak nakoming van dieet. Metodes: Die DBSPHR het proporsioneel geweegde komponente bevat, verwant aan die inname van vrugte en groente, laevet suiwelprodukte, volgraan voedsels, maer vleis, hoender en diskresionêre vet. Die studiepopulasie het volwasse Suid-Afrikaners ingesluit wat lede van die Discovery Vitality program was en wat die program se aanlyn gesondheidsrisiko assessering tussen 1 Februarie 2010 en 31 Januarie 2011 voltooi het. Gestratifiseerde, ewekansige steekproeftrekking was gebruik (n=1600). Helfte van die steekproef het lede ingesluit wat aan Vitality se HealthyFoodTM voordeel program deelgeneem het. Die verskillende Vitality Status groepe was gelyk verteenwoordig en reflekteer verskillende grade van interaksie met die program. Geslagte was gelyk verteenwoordig. DBSPHRs data was gekategoriseer as: Swak (Telling 0-18), Onvoldoende (18.5-22.5), Matig (23-26), Goed (26.5-29), Uitstekend (29.5-36). DBSPHR data was vir die volgende veranderlikes geanaliseer: Vitality status, deelname aan die HealthyFoodTM voordeel, rook, fisiese aktiwiteit, alkohol inname, liggaamsmassa indeks (LMI), ouderdom en geslag. Die verhouding tussen aaneenlopende reaksie veranderlikes en nominale inset veranderlikes was geanaliseer deur die gebruik van analise van variansies (ANOVA). Wanneer ordinale reaksie veranderlikes vergelyk was teenoor ‘n nominale inset variansie, was nie-parametriese ANOVA metodes gebruik. Verder was die Mann-Whitney toets of die Kruskal-Wallis toets gebruik. ‘n P-waarde van p < 0.05 was gesien as verteenwoordigend van statistiese beduidendheid en 95% sekerheidsintervalle was gebruik om die skatting van onbekende parameters te beskryf.Resultate: Van die studie monster het 67.13% van die lede DBSPHRs getoon wat gereken was as “swak” of “onvoldoende”. Die gemiddelde DBSPHR van die steekfproef was 20.47 punte. Vroue het beter DBSPHR as mans behaal (p<0.01). Meer interaksie met die Vitality program was geassosieer met beter DBSPHRs (p<0.01). Daar was geen beduidende verskille tussen die gemiddelde DBSPHR van lede wat aan die HealthyFoodTM voordeel program deelneem en die lede wat nie aan die program deelneem nie, alhoewel die HealthyFoodTM voordeel nie geëvalueer was as ‘n intervensie nie. Lede met “riskante” lewenstyl gedrag soos onaktiwiteit, rook en hewige alkoholinname het laer DBSPHR getoon as lede sonder hierdie risiko’s. Vetsugtige lede het laer DBSPHR behaal as normale gewig en oorgewig lede (p<0.01). Gevolgtrekking: Dit is ‘n bron van kommer dat Discovery Vitality lede nie beter vertoon het as wat blyk ‘n algemene globale standaard van gebrekkige nakoming van die “gees van leiding oor dieet” te wees nie. Interaksie met die Vitality program blyk ‘n positiewe impak te hê op dieet nakoming. Lede wat ‘n verhoogde risiko gehad het vir NOS morbiditeit en mortaliteit as gevolg van veroudering, vetsugtigheid, rook, onaktiwiteit of verontagsaming van alkohol inname riglyne het ook laer DBSPHRs getoon in vergelyking met lede sonder hierdie risiko’s. Geteikende intervensies gemik op die aanspreek van riskante dieet en lewenstyl gedrag mag tot voordeel van hierdie lede wees.

Texto completoMaize is the principal staple food/feed crop exposed to mycotoxins, and the co-occurrence of multiple mycotoxins and their metabolites has been well documented. Dietary (co)-exposure to mycotoxins is associated with human and animal health concerns as well as economic losses. The present thesis aims to apply a holistic approach for the risk assessment of mycotoxin mixtures in food and feed, i.e. from fungal production and occurrence to harmonised risk characterisation. This was done in three folds. Firstly, available environmental, ecological, and agronomic factors that may affect the relative abundance of co-occurring mycotoxins in the contaminated crops were collected from peer-reviewed literature, with focus on maize (Chapter I). Secondly, (co-)occurrence data on mycotoxins in core cereals was extracted from available articles in the scientific literature and analysed to estimate potential pattern of co-exposure in humans and animals (Chapter II). Finally, Chapter III investigates the applicability of the EFSA guidance to multiple mycotoxins through a scenario of possible co-exposure in humans and animals, using maize as a case study. In particular, a human and animal risk assessment to mycotoxin mixture in maize was conducted using a modelled component-based approach for selected mixture of mycotoxins, that, according to our data, co-occur in maize based feed and food products.

No Brasil, os riscos à saúde humana resultantes da exposição a compostos químicos vêm sendo abordados há poucos anos. Em 2009 foi publicada a Resolução CONAMA 420 que deu início à regulamentação desta prática e em 2013 o procedimento de avaliação de riscos à saúde humana em áreas contaminadas foi normatizado através da NBR 16209. Esta dissertação apresenta um estudo de avaliação de risco à saúde humana a partir de um estudo de caso de uma área contaminada com hidrocarbonetos policíclicos aromáticos (HPAs), considerando a exposição de futuros trabalhadores da área. Diante dos resultados obtidos foi realizada uma análise de sensibilidade dos parâmetros do meio físico da área de estudo para que fosse possível determinar e recomendar quais devem ser melhor investigados em estudos de áreas contaminadas com HPAs. Os resultados de risco à saúde humana mostraram que a rota de exposição mais crítica para o estudo de caso é a inalação de vapores em ambientes fechados, devido à ocorrência de compostos de baixo peso molecular, como o naftaleno. A análise de sensibilidade mostrou que o parâmetro do meio físico que exerceu maior influência nos resultados de risco à saúde humana foi a fração de carbono orgânico (FOC). Quanto maior a FOC menor foi o risco por inalação em ambientes abertos, fechados ou contato direto com a água subterrânea.
In Brazil, the risks to human health from exposure to chemical compounds have been discussed since few years ago. In 2009 federal resolution CONAMA 420 was published, starting the regulation of this practice, and in 2013 the procedure of human health risk assessment (HHRA) in contaminated areas was regulated by the Brazilian Regulatory Standard (NBR) 16209. This dissertation presents a HHRA for a case study of an area contaminated with Polycyclic Aromatic Hydrocarbons (PAHs), considering the exposure of future workers in the area. Based on the results a sensitivity analysis of the soil physical parameters of the study area was performed to determine and recommend which of the parameters should be further investigated in studies of areas contaminated with PAHs. The results of the HHRA showed that the most critical exposure pathway to case study is the inhalation of indoor air due to the occurrence of low molecular weight compounds such as naphthalene. The sensitivity analysis showed that the soil physical parameter that had greater influence on the risk results was the fraction of organic carbon (FOC). The higher the FOC the lower was the risk for inhalation in outdoor spaces, enclosed spaces or direct contact with groundwater.

Texto completoBackground The Disaster Management Act (Act 57 of 2002) instructs a paradigm shift from preparedness, response and recovery towards risk reduction. In order to plan for and mitigate risks, all spheres of government must firstly assess their hazards, vulnerabilities, capacity to cope and therefore risks. Studies in this regard, in South Africa, have however only focussed on current risks. Climate Change has now been accepted by leading international studies as a reality. Climate change can impact upon many aspects of life on earth. Studies to quantify the impact of climate change on water resources, biodiversity, agriculture and sustainable development are steadily increasing, but human health seem to have been neglected. Only general predictions, mostly regarding vector-borne disease and injury related to natural disasters are found in literature. Studies in South Africa have only focussed on malaria distribution. Most studies, internationally and the few in South Africa, were based on determining empirical relationships between weather parameters and disease incidence, therefore assessing only the hazard, and not the disaster risk. Methodology This study examines the impact of climate change on human health in the Western Cape, within the context of disaster management. A qualitative approach is followed and includes: · A literature overview examining predicted changes in climate on a global and regional scale, · A discussion on the known relationships and possible impacts climate change might have on human health, · A disaster risk assessment based on the status quo for a case study area, the Cape Winelands District Municipality, · An investigation into the future risks in terms of health, taking into account vulnerabilities and secondary impacts of climate change, resulting in the prioritisation of future risks. · Suggestions towards mitigation within the South African context. Results The secondary impacts of climate change were found to have the larger qualitative impact. The impact of climate change on agriculture, supporting 38% of the population can potentially destroy the livelihoods of the workforce, resulting in poverty-related disease. Other impacts identified were injuries and disease relating to temperature, floods, fire and water quality. Conclusion Risk is a function of hazard, vulnerability and capacity to cope. The impact of an external factor on a ‘spatial system’ should be a function of the impacts on all these factors. Disasters are not increasing because of the increase in the frequency of hazards, but because of the increasing vulnerability to hazards. This study illustrated that the major impacts of the external factor could actually be on the vulnerabilities and the indirect impacts, and not on the hazard itself. Climate change poses a threat to many aspects of the causative links that should be addressed by disaster management, and its impacts should be researched further to determine links and vulnerabilities. This research also illustrates that slow onset disasters hold the potential to destroy just as much as extreme events such as Katrina, Rita or a tsunami. It also reiterates that secondary impacts may not be as obvious, but are certainly not of secondary importance.

Texto completoNước ngầm là một trong những nguồn cung cấp nước chính cho sinh hoạt, tưới tiêu, nuôi trồng thủy sản và công nghiệp ở Đồng bằng sông Cửu Long. Cùng với sự gia tăng dân số, nước ngầm ngày càng đóng vai trò quan trọng hơn trong các hoạt động phát triển kinh tế - xã hội. Nghiên cứu đã tiến hành đánh giá diễn biến chất lượng nước ngầm thông qua số liệu của tám giếng quan trắc trong giai đoạn từ năm 2009 – 2016. Kết hợp với đánh giá rủi ro sức khỏe của người dân khi sử dụng nước ngầm chứa arsenic. Kết quả nghiên cứu cho thấy các giếng nước ngầm ở tỉnh An Giang đã bị nhiễm vi sinh. Tổng chất rắn hòa tan (TDS) và độ cứng ở trạm Phú Tân và Chợ Mới phân tích được cao hơn quy chuẩn cho phép (QCVN 09-MT:2015/BTNMT). Các giếng nước ngầm ở một số khu vực cù lao của tỉnh An Giang đã bị ô nhiễm hữu cơ và arsenic nghiêm trọng. Nồng độ arsenic trong nước ngầm có thể dao động lên đến 0.55 ± 1.21 mg/L. Rủi ro ung thư ở hai đối tượng người lớn và trẻ em khi sử dụng nước ngầm nhiễm arsenic dao động từ trung bình (8 người trong 1.000 người) tới cao (8 người trong 100 người). Cung cấp nguồn nước thay thế là giải pháp khả thi để giảm rủi ro sức khỏe cho con người trong trường hợp này. Ngoài ra, người dân địa phương cần được khám sức khỏe thường xuyên để kịp thời phát hiện và sớm điều trị bệnh.

Texto completoThe results demonstrated that the ABR and SER can be reliably recorded in newborns. Latency and morphological changes on serial testing reflected maturation of the nervous system. Chi square analysis revealed that an abnormal SER or ABR predicted neuromotor impairment at 1 year of age. The type of SER abnormality further delineated the degree of disability. A normal SER and ABR predicted normal neurodevelopmental outcome. In conclusion, multi-modality evoked response testing yielded valuable prognostic information for the newborn at high risk for neurologic sequelae.
