Early Growth and Later Health, Focus on Metabolic Syndrome, Obesity and Physical Activity

The Developmental Origins of Health and Disease Hypothesis proposes that adverse health outcomes in adult life are in part programmed during fetal life and infancy. This means that e.g. restricted nutrition during pregnancy programmes the offspring to store fat more effectively, to develop faster and to reach puberty earlier. These adaptations are beneficial in terms of short term survival. However, in developed countries these adaptations often lead to an increased risk of obesity and metabolic disturbances in later life, due to a mismatch between the prenatal and postnatal environment. This thesis aimed to study the role of early growth in people who are obese as adults, but metabolically healthy as well as in those who are normal in weight but metabolically obese. Other study aims were to assess whether physical activity and cardiorespiratory fitness are programmed early in life. The role of socioeconomic status in the development of obesity from a life course setting was also studied. These studies included 2003 men and women born in Helsinki between 1934 and 1944 with detailed information of their prenatal and childhood growth as well as living conditions. They participated in the detailed clinical examination during the years 2001-2004. A sub-group of the subjects participated in the UKK Institute 2-kilometre walk test. Metabolic syndrome was defined according to the 2005 criteria of the International Diabetes Federation. Among the obese men and women 20 % were metabolically healthy. Those with metabolic syndrome did not differ in birth size compared to the healthy ones, but by two years of age, they were lighter and thinner, and remained so up to 11 years. The period when changes in BMIs were predictive of the metabolic syndrome was from birth to 7 years. Of the normal weight individuals 17 % were metabolically obese. Again, there were no differences in birth size. However, by the age 7 years, those men who later developed metabolic syndrome were thinner. Gains in BMI during the first two years of life were protective of the syndrome. Children who were heavier, and especially taller, were more physically active, exercised with higher intensity and had higher cardiorespiratory fitness in their adult life than those who were shorter and thinner as children. Lower educational attainment and lower adult social class were associated with obesity in both men and women. Childhood social class was inversely associated with body mass index only in men while lower household income was associated with higher BMI in women. These results support the role of early life factors in the development of metabolic syndrome and adult life style. Early detection of risk factors predisposing to these conditions is highly relevant from a public health point of view.

Role of CIP2A in carcinogenesis

Worldwide and notably in the developed countries, cancer is an increasing cause of morbidity and mortality, being the second most common cause of death after ischemic heart disease. Now and in the future new cancer cases need to be diagnosed earlier. Prognostic factors may be helpful in recognizing and handling those patients who need more aggressive therapy, and it is also desirable to predict treatment response accurately. Cancerous inhibitor of protein phosphatase 2A (CIP2A) is an oncoprotein predominantly expressed in malignant tissues and inhibiting protein phosphatase 2A (PP2A) activity; it is a promising target for cancer therapy. The aim of this thesis was to evaluate the prognostic role of CIP2A in solid cancers, and for this purpose to explore expression of CIP2A, and investigating regulation of CIP2A in order to gain insight into signalling pathways leading to alteration in prognosis. Patients diagnosed with gastric, serous ovarian, tongue, or colorectal cancer at Helsinki University Central Hospital were included. Tumour tissue microarrays assembled from specimens from these patients were prepared and stained immunohistochemically for CIP2A protein expression. Associations with clinicopathologic parameters and other biomarkers were explored, and survival analyses were done according to the Kaplan-Meier method. Study of the role of CIP2A in intracellular signalling in vitro involved gastric, ovarian, and tongue cancer cell lines. We found CIP2A to be highly expressed in gastric, ovarian, tongue, and colorectal cancer specimens. CIP2A was associated with clinicopathologic parameters characterizing an aggressive disease, namely advanced stage, high grade, p53 immunopositivity, and high proliferation index. CIP2A led to recognition of gastric, ovarian, and tongue cancer patients with poor prognosis, however, with a cancer type-specific cut-off level for prognostic significance. In tongue cancer, it served as an independent prognostic marker. In contrast, in colorectal cancer, CIP2A provided no prognostic value. In cancer cell lines, CIP2A was highly expressed at both protein and mRNA levels, and promoted cell proliferation and anchorage-independent growth. In gastric cancer, we demonstrated with a MYCER construct in mouse embryo fibroblasts that activation of MYC led to increased CIP2A mRNA expression, and hence we suggested that a positive feedback mechanism between CIP2A and MYC may potentiate and prolong the oncogenic activity of these proteins. We demonstrated in ovarian cancer an association between CIP2A and EGFR protein overexpression and EGFR gene amplification. In ovarian and tongue cancer cells we showed that depletion of EGFR downregulates CIP2A expression. In conclusion, high CIP2A expression occurred frequently among patients with aggressive disease. CIP2A may serve as a prognostic marker in gastric, ovarian, and tongue cancer and thus may help in tailoring therapy for cancer patients. The positive feedback mechanism between CIP2A and MYC, as well as the positive regulation of CIP2A by EGFR, are a few signalling pathways regulating and regulated by CIP2A. These and other mechanisms need to be studied further, however. CIP2A is a potential target for therapy, and its potential role as predictive marker and as a tumour marker in serum requires exploration.

From polarization to convergence: need to mend the broken patent system

For more than two hundred years, the world has discussed the issue of whether to continue the process of patenting or whether to do away with it. Developed countries remain polarized for various reasons but nevertheless the pro patent regime continued. The result was a huge volume of patents. The present article explains the implications of excessive volume of patents and conditions under which prior art search fails. This article highlights the importance and necessity of standardization efforts so as to bring about convergence of views on patenting.

SpecNet: Spectrum Sensing Sans Frontieres

While the under-utilization of licensed spectrum based on measurement studies conducted in a few developed countries has spurred lots of interest in opportunistic spectrum access, there exists no infrastructure today for measuring real-time spectrum occupancy across vast geographical regions. In this paper, we present the design and implementation of SpecNet, a first-of-its-kind platform that allows spectrum analyzers around the world to be networked and efficiently used in a coordinated manner for spectrum measurement as well as implementa- tion and evaluation of distributed sensing applications. We demonstrate the value of SpecNet through three applications: 1) remote spectrum measurement, 2) primary transmitter coverage estimation and 3) Spectrum-Cop that quickly identifies and localizes transmitters in a frequency range and geographic region of interest.

How design process for the Base of the Pyramid differs from that for the Top of the Pyramid

The base (BOP) and the top (TOP) of the world income pyramid represent the poor people and the people from developed countries, respectively. The design of products for the BOP is an important ingredient of the poverty reduction approach that combines business development with poverty alleviation. However, the current understanding of the design for the BOP is limited. This study, using a protocol analysis, compared design processes for the BOP and TOP markets. The results indicate the difference between the design processes for these markets in terms of the design strategy employed by the designers (i.e. problem driven, solution driven strategy), their requirements handling behaviour, and their information behaviour.

Políticas públicas y desigualdades regionales en la distribución del ingreso en la Argentina

Resumen: El análisis de los indicadores de ingresos, desigualdad y pobreza en cada uno de los 32 centros urbanos muestra las grandes disparidades regionales de la Argentina. En la Zona Norte del país el ingreso per capita es un 35% inferior al promedio nacional, la pobreza es 4 veces mayor que en la capital y la distribución del ingreso es más desigual. Los datos estadísticos disponibles indican que el crecimiento económico y las políticas públicas que se han implementado recientemente han reducido los niveles de pobreza agregados, pero han tenido poco impacto en las regiones más pobres del país. Por otra parte, el impacto distributivo de las políticas y programas públicos en la Argentina es reducido cuando se los compara con lo que sucede en los países mas desarrollados. Se requiere el diseño y la implementación de nuevas políticas públicas de reducción de la pobreza que se focalicen en los problemas y dificultades específicas que enfrentan las regiones más pobres. Entre ellas se destaca la necesidad de políticas para disminuir la alta informalidad del empleo que caracteriza a estas zonas. Por otra parte, las nuevas políticas deberían transferir las responsabilidades y premiar los esfuerzos propios de los gobiernos locales, reemplazando la actual “cultura de la dependencia” de los programas del gobierno central por un desarrollo institucional local que enfatice la gestión eficiente de las administraciones públicas provinciales y el desarrollo del capital social local.

Autopercepción de la identidad en la transición a la edad adulta

[Es] La complejidad social de los países desarrollados, junto a la peculiaridad de los factores socioculturales de cada país y el protagonismo del sujeto en su propio desarrollo, están condicionando las diferentes trayectorias en el paso de la adolescencia a la edad adulta. La investigación que se presenta tiene por objeto profundizar en la autopercepción de la identidad personal y describir los procesos psicológicos que favorecen la madurez psicológica y la autonomía personal a pesar de mantener relaciones y estados de dependencia familiar y económica. Se han encuestado a un total de 231 varones y mujeres, de edades comprendidas entre los 19 y los 30 años de edad, para saber cómo se definen en relación con su identidad personal y cuáles son las razones que les lleva a tal percepción. Los resultados demuestran que hay hasta cuatro identidades diferenciadas en la década de los 20 a los 30 años, basadas en un proceso subjetivo del desarrollo del yo individual orientado hacia la madurez psicológica, más que en otros acontecimientos sociales más o menos normativos.

Associação entre baixa estatura e sobrepeso em mulheres brasileiras

A associação entre o déficit nutricional em períodos recentes da vida com as doenças crônico-degenerativas e o excesso de peso, tem sido investigada principalmente em países desenvolvidos. No Brasil a associação tem se mostrado significativa apenas no sexo feminino. A realização de um estudo com a população feminina em idade reprodutiva contribuiria para explicar as diferenças de gênero observadas nas altas prevalências de sobrepeso em mulheres no país. Avaliar a associação entre baixa estatura, sobrepeso e ganho excessivo de peso. Este estudo foi baseado na Pesquisa Nacional de Demografia e Saúde (DHS-96). Trata-se de um estudo seccional de representatividade nacional. Todas as análises foram realizadas agrupando as regiões em Rural; Norte e Nordeste; Sul; Sudeste e Centro-Oeste. A população elegível para esta análise foi de 2.292 mães com idade entre 20 e 45 anos. Foram excluídas da análise: mulheres grávidas no momento do inquérito; com último parto anterior a seis meses ou menos da entrevista; não pesadas e não medidas. Os resultados mostraram associação entre a baixa estatura e sobrepeso anterior a primeira gravidez e indicam que a baixa estatura pode estar associada com ganho excessivo de peso no período reprodutivo. Entretanto, os diferenciais observados em relação a região Centro-Sul, consideram a possibilidade da baixa estatura ser um marcador de diferentes contextos sócio-econômicos associados a evolução dos problemas nutricionais no país.
