Prevalence, Abundance, and Virulence of Adherent-Invasive Escherichia coli in Ulcerative Colitis, Colorectal Cancer, and Coeliac Disease

Adherent-invasive E. coli (AIEC) has largely been implicated in the pathogenesis of Crohn's disease (CD). E. coli strains with similar genetic backgrounds and virulence genes profiles have been associated with other intestinal disorders, such as ulcerative colitis (UC), colorectal cancer (CRC), and coeliac disease (CeD), but the role of AIEC in these diseases remains unexplored. We aimed to assess the distribution, abundance, and pathogenic features of AIEC in UC, CRC, and CeD.This work was funded by the Spanish Ministry of Education and Science through projects SAF2010-15896, SAF2013-43284-P, and SAF2107-82261-P (MINECO/AEI/FEDER/UE) and the grant AGL2017-88801-P from the Spanish Ministry of Science and Innovation (MICINN, Spain).

Melanoma-specific survival is worse in the elderly: a multicentric cohort study

We aimed to characterise cutaneous melanoma in the elderly and determine its association with poorer prognosis. We studied a prospective cohort of the melanoma population in Catalonia between 2012 and 2016. We compared young patient group (= 75 years old). We included 3009 patients (52.5% women) from 14 centres, with a mean age at diagnosis of 61.1 years. In the >= 75-year-old group there was a predominance of men (53.9% vs. 45.5%, P = 75 years regardless of gender, location, IB, ulceration and lymph node status at diagnosis (HR 1.54, P = 0.013) whereas MFS was not independently associated with elderly when head and neck location was considered. Age appears to be an independent risk factor for MSS but not for MFS. Worse melanoma prognosis in elderly could be explained by factors unrelated to the tumour, such as age-related frailty and comorbidities that limit the access to systemic treatments and, eventually, age-related immune dysfunction

Incidence of melanoma in Catalonia, Spain, is rapidly increasing in the elderly population. A multicentric cohort study

The incidence of melanoma has been increasing worldwide during recent decades. The objective of the study was to analyse the trends in incidence for in situ and invasive melanoma in the Spanish region of Catalonia during the period of 2008-2017. We designed a cross-sectional study with an age-period-cohort analysis of melanoma patient data from the Network of Melanoma Centres in Catalonia. Our database covered a population of over seven million and included a total of 8626 patients with incident melanoma. The main outcome measures were crude and age-standardised incidence rates to the European 2013 standard population. Joinpoint regression models were used to evaluate the population trends. We observed an increase in the age-standardised incidence rate (per 100,000 population) of all melanoma subtypes from 11.56 in 2008 to 13.78 in 2017 with an average annual percent change (AAPC) of 3.5%. This incidence increase was seen exclusively in the older population. Moreover, the stratified analysis showed a statistically significant increase in the age-standardised incidence rate for invasive (AAPC 2.1%) and in situ melanoma (AAPC 6.5%). In conclusion, the incidence of melanoma has continued to increase in the elderly population over recent decades, with a rapidly increasing trend of in situ melanomas and the lentigo maligna subtype

Melanoma Incidence Increases in the Elderly of Catalonia But Not in the Younger Population: Effect of Prevention or Consequence of Immigration?

All cases of MM diagnosed in 23 Hospitals in Catalonia, from 2000 to 2007 were recorded and its incidence calculated and adjusted for the European standard population through the direct method. The age standardized rate varied from 6.74 in 2000 to 8.64 in 2007 for all melanomas and from 4.79 to 5.80 for invasive MMs, the Breslow thickness being stable during the period. The increase in invasive melanoma incidence in the elderly was remarkable, the crude rate increasing from 11.04 (2000) to 15.49 (2007) in the 60–64 yr population, while remaining more stable from 3.97 in 2000 to 4.55 in 2007 for the age range of 30–34 ys or with a tendency to decrease from 5.1 in 2000 to 2.5 in 2007 for age range of 25–29 yr, age ranges much more affected by immigration. Despite the large immigrant population (nearly one million immigrants that arrived in Catalonia during the study period from countries with a low melanoma incidence), melanoma incidence in our region has risen considerably and this trend will likely persist in the near future

The age standardised rate/100,000 inhabitants varied from 6.74 in 2000 to 8.64 in 2007 for all melanomas and from 4.79 to 5.80 for invasive MMs; the Breslow thickness was stable during the period.
