Mexico city in José Joaquín Blanco’s chronicles
Este artículo analiza la imagen de la Ciudad de México configurada en la crónica mexicana a partir de los años setenta en especial en los textos de José Joaquín Blanco. Se detiene en el modo en que el género afronta la realidad de una megalópolis que ya solo puede ser asumida de modo fragmentario y múltiple. Entre la utopía y una visión apocalíptica de la ciudad, la crónica reconfigura el espacio y el tiempo urbanos, y formula una nueva identidad crítica gracias a la habilitación de espacios de expresión posibles dentro de las nuevas ciudades modificadas por el capital.The article analyses the image of Mexico City developed in the Mexican chronicle after the seventies, especially in José Joaquín Blanco texts. It focuses on how the genre faces the reality of a megalopolis which can only be conceived in a fragmentary way and from a multiple viewpoint. Between the utopia and an apocalyptic vision of the city, the chronicle reshapes the urban space and time, and formulates a new critical identity by means of adapting possible places for expression inside the new cities modified by capital

Obesity and Bone Health: A Complex Relationship
Recent scientific evidence has shown an increased risk of fractures in patients with obesity,
especially in those with a higher visceral adipose tissue content. This contradicts the old paradigm
that obese patients were more protected than those with normal weight. Specifically, in older subjects
in whom there is a redistribution of fat from subcutaneous adipose tissue to visceral adipose tissue and
an infiltration of other tissues such as muscle with the consequent sarcopenia, obesity can accentuate
the changes characteristic of this age group that predisposes to a greater risk of falls and fractures.
Other factors that determine a greater risk in older subjects with obesity are chronic proinflammatory
status, altered adipokine secretion, vitamin D deficiency, insulin resistance and reduced mobility. On
the other hand, diagnostic tests may be influenced by obesity and its comorbidities as well as by body
composition, and risk scales may underestimate the risk of fractures in these patients. Weight loss
with physical activity programs and cessation of high-fat diets may reduce the risk. Finally, more
research is needed on the efficacy of anti-osteoporotic treatments in obese patients.Instituto de Salud Carlos IIIEuropean Commission CD20/00022

Mechanisms Involved in the Relationship between Vitamin D and Insulin Resistance: Impact on Clinical Practice
This research was funded by the Institute of Health Carlos III grants (PI18-00803 and PI18-01235), co-funded by the European Regional Development Fund (FEDER) and Junta de Andalucia (PI-0268-2019). In addition, V.C.-B. and C.G.-F. are funded by postdoctoral fellowships from the Junta de Andalucia and Institute of Health Carlos III respectively (RH-0141-2020; CD20/00022).Recent evidence has revealed anti-inflammatory properties of vitamin D as well as extraskeletal
activity. In this context, vitamin D seems to be involved in infections, autoimmune diseases,
cardiometabolic diseases, and cancer development. In recent years, the relationship between vitamin
D and insulin resistance has been a topic of growing interest. Low 25-hydroxyvitamin D (25(OH)D)
levels appear to be associated with most of the insulin resistance disorders described to date. In fact,
vitamin D deficiency may be one of the factors accelerating the development of insulin resistance.
Vitamin D deficiency is a common problem in the population and may be associated with the pathogenesis
of diseases related to insulin resistance, such as obesity, diabetes, metabolic syndrome (MS)
and polycystic ovary syndrome (PCOS). An important question is the identification of 25(OH)D levels
capable of generating an effect on insulin resistance, glucose metabolism and to decrease the risk of
developing insulin resistance related disorders. The benefits of 25(OH)D supplementation/repletion
on bone health are well known, and although there is a biological plausibility linking the status of
vitamin D and insulin resistance supported by basic and clinical research findings, well-designed
randomized clinical trials as well as basic research are necessary to know the molecular pathways
involved in this association.Institute of Health Carlos III grants PI18-00803

Nutrients and Dietary Patterns Related to Osteoporosis
Osteoporosis is a common chronic disease characterized by a decrease in bone mineral
density, impaired bone strength, and an increased risk of fragility fractures. Fragility fractures are
associated with significant morbidity, mortality and disability and are a major public health problem
worldwide. The influence of nutritional factors on the development and progression of this disease
can be significant and is not yet well established. Calcium intake and vitamin D status are considered
to be essential for bone metabolism homeostasis. However, some recent studies have questioned the
usefulness of calcium and vitamin D supplements in decreasing the risk of fractures. The adequate
intake of protein, vegetables and other nutrients is also of interest, and recommendations have been
established by expert consensus and clinical practice guidelines. It is important to understand the
influence of nutrients not only in isolation but also in the context of a dietary pattern, which is a
complex mixture of nutrients. In this review, we evaluate the available scientific evidence for the
effects of the main dietary patterns on bone health. Although some dietary patterns seem to have
beneficial effects, more studies are needed to fully elucidate the true influence of diet on bone fragility.Instituto de Salud Carlos III

Vitamin D Status, Calcium Intake and Risk of Developing Type 2 Diabetes: An Unresolved Issue
The relationship between vitamin D status, calcium intake and the risk of developing
type 2 diabetes (T2D) is a topic of growing interest. One of the most interesting non-skeletal
functions of vitamin D is its potential role in glucose homeostasis. This possible association is
related to the secretion of insulin by pancreatic beta cells, insulin resistance in different tissues and its
influence on systemic inflammation. However, despite multiple observational studies and several
meta-analyses that have shown a positive association between circulating 25-hydroxyvitamin D
concentrations and the risk of T2D, no randomized clinical trials supplementing with different doses
of vitamin D have confirmed this hypothesis definitively. An important question is the identification
of what 25-hydroxyvitamin D levels are necessary to influence glycemic homeostasis and the risk of
developing T2D. These values of vitamin D can be significantly higher than vitamin D levels required
for bone health, but the currently available data do not allow us to answer this question adequately.
Furthermore, a large number of observational studies show that dairy consumption is linked to
a lower risk of T2D, but the components responsible for this relationship are not well established.
Therefore, the importance of calcium intake in the risk of developing T2D has not yet been established.
Although there is a biological plausibility linking the status of vitamin D and calcium intake with the
risk of T2D, well-designed randomized clinical trials are necessary to answer this important question
Frecuencia de parasitismo intestinal en pacientes atendidos en la Clínica de Bienestar Universitario de la universidad de El Salvador de Enero a Marzo del 2016.
El Salvador es un país en vías de desarrollo en donde prevalecen condiciones socioeconómicas, demográficas, educacionales, ambientales e infraestructura de servicios básicos inadecuados. La inexistencia de condiciones básicas de salud, la poca educación y práctica de hábitos de salubridad en la población, favorecen la incidencia y prevalencia de parasitismo intestinal, en todo el territorio nacional.
El control de los factores de riesgo es importante para la solución de este problema, pero la falta de conciencia de la población y sus condiciones básicas no han permitido la desaparición del parasitismo o que éste disminuya significativamente.
El objetivo del presente trabajo es conocer cuáles son los parásitos más frecuentes en la población que consulta en la Clínica de Bienestar Universitario de la Universidad de

The Influence of the Mediterranean Dietary Pattern on Osteoporosis and Sarcopenia
Diet is a modifiable factor in bone and muscle health. The Mediterranean diet (MedDiet) is
rich in nutrients and contains key bioactive components with probable protective effects on muscle
and bone deterioration. Osteoporosis (OP) and sarcopenia are diseases that increase frailty and
susceptibility to fracture, morbidity and mortality. Therefore, it is necessary to combat them in
the population. In this regard, MedDiet adherence has proven to be beneficial to bone mineral
density (BMD), muscle mass, physical function, OP and sarcopenia. Hence, this diet is proposed as a
therapeutic tool that could slow the onset of osteoporosis and sarcopenia. However, there is doubt
about the interaction between the MedDiet, strength and fracture risk. Perhaps the amount of EVOO
(extra virgin olive oil), fruits, vegetables and fish rich in anti-inflammatory and antioxidant nutrients
ingested has an influence, though the results remain controversiaInstitute of Health Carlos III grants (PI21-01069, PI18-01235
