Fluid–structure interaction analysis of eccentricity and leaflet rigidity on thrombosis biomarkers in bioprosthetic aortic valve replacements
This work intends to study the effect of aortic annulus eccentricity and leaflet rigidity on the performance, thrombogenic risk and calcification risk in bioprosthetic aortic valve replacements (BAVRs). To address these questions, a two-way immersed fluid–structure interaction (FSI) computational model was implemented in a high-performance computing (HPC) multi-physics simulation software, and validated against a well-known FSI benchmark. The aortic valve bioprosthesis model is qualitatively contrasted against experimental data, showing good agreement in closed and open states. Regarding the performance of BAVRs, the model predicts that increasing eccentricities yield lower geometric orifice areas (GOAs) and higher normalized transvalvular pressure gradients (TPGs) for healthy cardiac outputs during systole, agreeing with in vitro experiments. Regions with peak values of residence time are observed to grow with eccentricity in the sinus of Valsalva, indicating an elevated risk of thrombus formation for eccentric configurations. In addition, the computational model is used to analyze the effect of varying leaflet rigidity on both performance, thrombogenic and calcification risks with applications to tissue-engineered prostheses. For more rigid leaflets it predicts an increase in systolic and diastolic TPGs, and decrease in systolic GOA, which translates to decreased valve performance. The peak shear rate and residence time regions increase with leaflet rigidity, but their volume-averaged values were not significantly affected. Peak solid stresses are also analyzed, and observed to increase with rigidity, elevating risk of valve calcification and structural failure. To the authors' knowledge this is the first computational FSI model to study the effect of eccentricity or leaflet rigidity on thrombogenic biomarkers, providing a novel tool to aid device manufacturers and clinical practitioners.This project has received funding from the European Union's Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No. 713673.

The right to adequate food: how the COVID-19 pandemic affected access to food in Mexico and Scotland
BACKGROUND: How people accessed food during the COVID-19 pandemic
was influenced by factors such as: losing one’s income; changes in households’
routines and structure; a changed food environment; and the availability of social
protection policies. This thesis explored how the COVID-19 pandemic, and the
lockdown implemented by the Mexican and the Scottish governments, impacted food
and nutrition security, and the right to adequate food, of individuals in these two
countries.
METHODS: Using a case study methodology (Mexico and Scotland being the
cases) with a critical realist ontology, and a contextualist epistemology, I built both
cases from three different data sources, considered as studies 1,2 and 3. Study 1
involved a qualitative evidence synthesis of papers that had researched access to food
by vulnerable populations using photo-elicitation interviews or focus groups.
This review
provided insight into how researchers have used photo-elicitation to research
food/nutrition (in)security in different settings. Study 2 were online photo-elicitation semi-structured interviews with participants from households, where one or more members
lost their jobs in Mexico and Scotland. Study 3 comprised online semi-structured
interviews with stakeholders (academia, government and third sector organizations) in
both countries.
FINDINGS: The findings from the review were used to inform the utilization of the
method in the households’ online interviews (study no. 2). It also provided valuable
information to validate the findings of studies 2 and 3. In study 2, I interviewed members
from 11 households in Mexico (from urban and urban areas) and 7 in Scotland (urban
areas). The participants from Scotland experienced the COVID-19 pandemic in a less
concerning manner, by showing less vulnerability to food and nutrition insecurity at the
time of the interviews compared with the ones in Mexico. Social protection policies had
an impact on how people in both countries experienced access to food. For example,
the furlough scheme, availability of food aid, and a responsive food system contributed
to a better experience for the families in Scotland. On the other hand, participants in
Mexico, from both rural and urban areas, experienced deep and chronic stress related
to the financial constraints. Those living in urban areas reported adaptations to their
food-related behaviours to cope with the challenges of accessing food and financial
vulnerability. In rural areas of Mexico, despite losing their source of income, the ability to
grow their own food provided a sense of security and put an emphasis on the value of
land.
Fifteen stakeholders (eight Mexican and seven Scottish) were interviewed in
study 3. Differences between Mexican and Scotland in terms of their understanding of
the right to food and perceptions of the pandemic’s impact were identified. The right to
food in Scotland is widely and thoroughly known by stakeholders, as well as in its
implications. In Mexico, most stakeholders had heard of it, but did not know all of its
components. An association between provision of food and the right to food was
highlighted in Mexico, which in Scotland was mostly criticized (food relief system has
grown significantly and diverts focus from structural problems). Despite the criticism, in
Scotland, food aid was plentiful during the pandemic, and a wide response from third
sector organizations to provide food was reported. Stakeholders in Mexico widely
referred to important ongoing social issues in the country such as the obesity and
diabetes epidemic, poverty, violence associated to drug cartels which they felt amplified
the negative impact of the pandemic.
CONCLUSION: Through triangulation of data, it was possible to understand how
the pandemic impacted each of the countries regarding food and nutrition security. The
impact of the pandemic was different in each country. The COVID-19 pandemic
represented a situation that unveiled many of the issues that represented an obstacle
for people to achieve food and nutrition security. The findings in this dissertation
contribute to the literature on the benefits of social protection measures, as well as the
need of strengthening mechanisms and institutions to make the right to adequate food
achievable for everyone, with the active participation of the government, third sector
organizations, and the private sector
Anxiety, depression and coping in patients with testicular cancer treatment and follow-up period
Introducción: El cáncer de testículo (CT) constituye la neoplasia más común entre los 15 y 39 años. Debido a su incidencia cada vez mayor y a su alta tasa de supervivencia, la literatura se ha centrado en el impacto que puedan tener las secuelas del tratamiento a mediano y a largo plazo. El CT y su asociación con la ansiedad y la depresión constituyen problemas psicológicos frecuentes durante el tratamiento y periodo de seguimiento, en este contexto el afrontamiento ante la enfermedad puede representar un mecanismo de mejor adaptación psicológico. Objetivo: Identificar y comparar los niveles de ansiedad y depresión en pacientes en tratamiento y periodo de seguimiento; así como su relación con los diferentes estilos de afrontamiento positivo. Método: 49 pacientes en tratamiento y 84 en periodo de seguimiento del Instituto Nacional de Cancerología. Se empleo un diseño transversal, no experimental y ex-post-facto. Se utilizaron los Inventarios de Ansiedad de Beck –BAI–, el Inventario de Depresión de Beck –BDI–, y el Instrumento de afrontamiento al estrés de Lazarus y Folkman. Resultados: Se identificaron mayores niveles de ansiedad y depresión en el grupo de pacientes en tratamiento. Se identificó una relación inversamente proporcional entre los estilos de afrontamiento positivos y menores niveles de sintomatología ansiosa y depresiva en ambos grupos. Conclusiones: Se corrobora la asociación entre los estilos de afrontamiento positivos y niveles bajos de ansiedad y depresión. Se recomienda promover en el paciente con CT afrontamiento positivo durante el tratamiento y periodo de seguimiento.Background: Testicular cancer is the most common malignancy between 15 and 39 years old. Due to the increasing incidence and high survival rate of patients with testicular cancer (CT), literature has focused on the impact that may have the aftermath of medium and long term treatment. The CT and its association with anxiety and depression are common psychological problems, in this context, active coping with this disease may represent a psychological best adaptation mechanism. Objective: To identify and compare the levels of depression and anxiety in patients in treatment and follow-up period; as well as his relationship with positive coping styles. Participants and methods: 49 patients in treatment and follow-up period 84 in the National Cancer Institute follow-up period. It is a transversal, retrospective, not experimental and ex-post-facto. The inventories of Beck Depression –BDI– (1961), the Beck anxiety inventory –BAI– (1988) and the instrument of Lazarus and Folkman (1985) for coping with the stress. Results: Higher levels of anxiety and depression in patients in treatment. If you can identify an inversely proportional relationship between positive coping styles and lower levels of anxious and depressive symptoms in both groups Conclusions: Is confirmed the association between positive coping styles and low levels of depression and anxiety. It is recommended to promote in patients with CT positive coping during treatment and follow-up perio
Duración de la lactancia y desarrollo psicomotor en infantes de un programa de seguimiento
El abandono temprano de la lactancia materna representa un problema de salud
pública, por tanto es necesario comprender los factores de riesgo y construir alternativas
para fomentarla. El objetivo del presente trabajo es describir el nivel de desarrollo psicomotor
a los 8 y 12 meses de edad, con respecto a la duración de la lactancia materna.
Participaron 112 lactantes quiénes cubrieron los requisitos de inclusión. Se formaron dos
grupos según el tiempo de lactancia materna predominante: suspensión temprana (hasta
tres meses) y lactancia extendida (cuatro y más meses). Los resultados mostraron que
47% de los niños del primer grupo, tuvieron un mejor desarrollo comparados con los del
grupo de lactancia extendida, quiénes tuvieron mayor prevalencia de malnutrición. Los
datos confirman la necesidad de conducir nuevos estudios que integren otras variables de
interés cuya contribución a la promoción de la lactancia exclusiva hasta los seis meses
y el desarrollo sean relevantes.The early abandonment of the breastfeeding represents a problem of public health,
therefore it is necessary to understand the risk factors and of constructing alternatives
to foment it. The objective of the present work is to describe the level of psychomotor
development to the 8 and 12 months of age, with respect to the duration of the breastfeeding
112 suckling babies participated that covered the requirements with inclusion. Two
groups formed according to the time of predominant breastfeeding: early suspension (up
to three months) and extended breastfeeding (four and more months). The results showed
that 47% of the children of the first group, had a better development compared with those of the group of extended breastfeeding, who had greater prevalence of malnutrition. The
data confirm the necessity to lead new studies that integrate other variables of interest
whose contribution to the promotion of the exclusive breastfeeding until the six months
and the development, are relevant
