High Levels of Circulating Chemokine (C-X-C motif) Ligand 11 Are Associated with Euthyroid or Subclinically Hypothyroid Autoimmune Thyroiditis and with Chemokine (C-X-C Motif) Ligand 10
No full textNo data are available for chemokine (C-X-C motif) ligand 11 (CXCL11), together with CXCL10, circulating levels in autoimmune thyroiditis (AT). We measured serum CXCL11 and CXCL10 in 158 patients with newly diagnosed AT (26% with subclinical hypothyroidism), 56 euthyroid controls, and 20 patients with nontoxic multinodular goiter, all similar in gender distribution and age. CXCL11 was significantly higher in patients with AT (113±56 pg/mL) than in controls (67±16 pg/mL) or patients with multinodular goiter (75±18 pg/mL; P<0.0001). Among patients with AT, CXCL11 was significantly higher in those with a hypoechoic ultrasonographic pattern and hypothyroidism. In a multiple linear regression (MLR) model including age, thyroid volume, hypoechogenicity, hypervascularity, thyroid-stimulating hormone (TSH), and anti-thyroid peroxidase, age (P=0.009) and TSH (P<0.008) were significantly related to serum CXCL11. In an MLR model of CXCL11 (ln[pg/mL]) versus age, TSH, CXCL10 (ln[pg/mL]), TSH (P=0.028), and CXCL10 (P=0.003) were significantly and independently related to CXCL11. We first show that circulating CXCL11, together with CXCL10, is increased in patients with thyroiditis and hypothyroidism, and is related to CXCL10 levels. These results underline the importance of a Th1 immune attack in the initiation of AT
Demographic sustainability in Italian territories: The link between depopulation and population ageing
No full textSince the Second World War, Italy has experienced major demographic changes,
including increasing survival, decreasing fertility and higher rates of immigration.
These changes have silently and slowly led to important shifts in the structure and the
territorial distribution of the population. Thus, like in many other European countries,
population ageing and depopulation have become the most relevant demographic
phenomena in Italy. In this paper, we studied the relationship between depopulation
and ageing in Italian territories in the 1971–2019 period using the census data of
the Italian municipalities and applying spatial techniques. We found that high levels
of depopulation later result in high levels of population ageing, and that recent
population ageing processes are also connected to ongoing depopulation processes,
thereby creating a vicious circl
Lo spopolamento nei comuni italiani: un fenomeno ancora rilevante
No full textIn European Countries, many territories experienced and are still experiencing a depopulation. The negative balance of births and deaths is combined with a negative net migration. At the same time, the decrease in births and increase in life expectancy caused the population ageing. Depopulation is strongly connected with population ageing. The aim of this work is to understand the relationship between depopulation and ageing population and the sustainability of a high level of two phenomena. We study these phenomena and their relationship in the Italian territories in the period 1951-2011. We analyse the most detailed administrative level, the municipalities. Census data are used.
Correlation coefficient between depopulation and population ageing indicators are calculated in order to investigate the association between the two phenomena. A regression model is applied in order to understand if population ageing is determined by the population variations. Finally, the municipalities, which experienced continuing depopulation, are examined in depth. A strong depopulation has determined the high level of population ageing, but the recent population ageing has contributed to the ongoing depopulation, creating a vicious circle. Long-term depopulation and strong ageing population seem to be not sustainable in the near future
Population ageing in Italy after the 2008 economic crisis: a demographic approach
No full textPopulation ageing is a significant demographic change. The Italian population is one of the oldest in the world. Studies have demonstrated that the economic crisis, beginning in 2008, is related to demographic dynamics. We believe that this crisis has an impact on Italian population ageing. We show that effects of the current economic crisis on population ageing are already observable. We predict how the current economic crisis will affect population ageing in the future until 2026. We estimate the number of births and net migration entries that did not take place due to the economic crisis. We find that missing births and missing net migration entries attributed to the current economic crisis have already had and will have an effect on the speed of population ageing in Italy. The demographic effects of this short-term economic crisis will become even more visible in the future. The results can help institutions have an overview of the consequences of the worsening demographic dynamics on the population structure due to adverse economic conditions. This paper is an important warning about the consequences of unexpected shocks. Demographic scientists, as well as policymakers, should be very interested in our results
