Hospitalizations and emergency department visits trends among elderly individuals in proximity to death: a retrospective population-based study.

Acute healthcare services are extremely important, particularly during the COVID-19 pandemic, as healthcare demand has rapidly intensified, and resources have become insufficient. Studies on specific prepandemic hospitalization and emergency department visit (EDV) trends in proximity to death are limited. We examined time-trend specificities based on sex, age, and cause of death in the last 2 years of life. Datasets containing all hospitalizations and EDVs of elderly residents in Friuli-Venezia Giulia, Italy (N = 411,812), who died between 2002 and 2014 at ≥ 65 years, have been collected. We performed subgroup change-point analysis of monthly trends in the 2 years preceding death according to sex, age at death (65-74, 75-84, 85-94, and ≥ 95 years), and main cause of death (cancer, cardiovascular, or respiratory disease). The proportion of decedents (N = 142,834) accessing acute healthcare services increased exponentially in proximity to death (hospitalizations = 4.7, EDVs = 3.9 months before death). This was inversely related to age, with changes among the youngest and eldest decedents at 6.6 and 3.5 months for hospitalizations and at 4.6 and 3.3 months for EDVs, respectively. Healthcare use among cancer patients intensified earlier in life (hospitalizations = 6.8, EDVs = 5.8 months before death). Decedents from respiratory diseases were most likely to access hospital-based services during the last month of life. No sex-based differences were found. The greater use of acute healthcare services among younger decedents and cancer patients suggests that policies potentiating primary care support targeting these at-risk groups may reduce pressure on hospital-based services.

[Early effects of attendance to the Friuli Venezia Giulia (Northern Italy) mammography screening programme on the incidence of advanced-stage breast cancer: a cohort study]. / Effetti precoci dell'adesione al programma di screening mammografico della Regione Friuli Venezia Giulia sull'incidenza del cancro della mammella in stadio avanzato: uno studio di coorte.

OBJECTIVES: to evaluate the incidence of advanced-stage breast cancer (BC) - an early surrogate indicator of effectiveness of mammography screening - among women who attended the Friuli Venezia Giulia (FVG) Region (Northern Italy) screening programme compared to women who did not attend. DESIGN: retrospective cohort study. Women invited to the first screening round (2006-2007) were identified from the database of the programme. The cohort was record-linked to the archive of women invited to the second round (2008-2009). The definition of attendance to screening was based on attendance to at least one of the two rounds. The incidence of BC was assessed through record linkage with the FVG cancer registry using an anonymous univocal identifier (end of follow-up: 31st December 2013). Three distinct definitions of advanced stage were used: pT2 or greater (pT2+), positive lymph nodes (pN+), and TNM stage II or greater (stage II+). SETTING AND PARTICIPANTS: organized mammography screening programme for women aged 50-69 years in the five regional healthcare districts. MAIN OUTCOME MEASURES: incidence rate ratio (IRR) between attenders and non-attenders, adjusted for age and deprivation index, with 95% confidence interval (95%CI). RESULTS: the cohort included 104,488 attenders and 49,839 non-attenders. During follow-up (median duration 84 months), 2,717 invasive BCs were diagnosed among attenders and 1,149 among non-attenders. Total incidence rate was 13% higher among attenders (IRR 1.13; 95%CI 1.05-1.21). These, conversely, had a 36% lower rate of pT2+ BC (IRR 0.64; 95%CI 0.56-0.72), a 13% lower rate of pN+ BC (IRR 0.87; 95%CI 0.78-0.98), a 22% lower rate of stage II+ BC (IRR 0.78; 95%CI 0.70-0.87), and a 32% lower rate of mastectomy (IRR 0.68; 95%CI 0.60-0.78). CONCLUSIONS: attenders had lower incidence rates of advanced-stage BC. This early effect is suggestive of a future impact of the screening programme on BC mortality.

Risk of Prevalent Asthma among Children Affected by Inflammatory Bowel Disease: A Population-Based Birth Cohort Study.

Literature on the risk of asthma among children with inflammatory bowel disease (IBD) is limited and has reported discording results. To the best of our knowledge, no previous study has evaluated the association between asthma and childhood onset IBD, focusing on pediatric IBD with onset between 10 and 17 years, early-onset IBD (EO-IBD) between 0 and 9 years, and very early-onset IBD (VEO-IBD) between 0 and 5 years, all conditions characterized by different clinical progressions. A nested matched case-control design on a longitudinal cohort of 213,515 newborns was adopted. Conditional binomial regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CI) of asthma among children with IBD compared with controls. We found 162 children with IBD and 1620 controls. Overall, childhood onset IBD was associated with increased risks of being affected by asthma (OR: 1.49 95% CI 1.05-2.12), although a significant risk was only present among males (OR: 1.60 95% CI 1.02-2.51). Children with Crohn's disease and ulcerative colitis had similarly increased risks, although they failed to attain statistical significance. Risks of asthma based on age at IBD onset were inversely related to age, with the lowest non-significant risks for pediatric IBD and EO-IBD, while children affected by VEO-IBD had the highest risk of asthma (OR: 2.75 95% CI 1.26-6.02). Our study suggests the presence of a higher prevalence of asthma among both male children with IBD and children with VEO-IBD. It could be advisable to pay greater attention to possible respiratory symptoms among these categories at higher risk.

Risk of intestinal and extra-intestinal cancers in patients with inflammatory bowel diseases: A population-based cohort study in northeastern Italy.

The cancer risk of patients with inflammatory bowel diseases (IBD) has not been well documented in southern Europe. This study aimed to evaluate the overall pattern of cancer risk among patients with IBD in Friuli Venezia Giulia, northeastern Italy. A population-based cohort study was performed through a record linkage between local healthcare databases and the cancer registry (1995-2013). We identified 3664 IBD patients aged 18-84 years, including 2358 with ulcerative colitis (UC) and 1306 with Crohn's disease (CD). Sex- and age-standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) were used to compare the cancer incidence of IBD patients with the general population. The cumulative cancer risk among IBD patients reached about 10% after 10 years of follow-up. A total of 246 cancers occurred among UC patients (SIR = 1.05, 95% CI: 0.92-1.19), and 141 among CD patients (SIR = 1.20, 95% CI: 1.01-1.41). As compared with the general population, no increased risk of colorectal cancers was observed for either UC or CD patients, whereas the risk of anal cancer was significantly elevated among UC patients (SIR = 6.03, 95% CI: 1.24-17.60). Increased risks were seen for specific extra-intestinal cancers, including corpus uteri (SIR = 2.67, 95% CI: 1.07-5.50) and kidney (SIR = 2.06, 95% CI: 1.03-3.69) among UC patients; thyroid (SIR = 5.58, 95% CI: 2.41-11.00) and skin non-melanoma (SIR = 1.86, 95% CI: 1.32-2.55) among CD patients. This population-based study showed that both UC and CD patients had a colorectal cancer risk similar to that of the general population. However, they were at a higher risk of developing certain extra-intestinal cancer types. Although detection biases cannot be excluded, the study findings pointed to a role of long-standing exposures to immunosuppressive therapies, underlying disease status, as well as the interactions with lifestyle factors. Our findings lent additional support to the need for monitoring the cancer burden in this at-risk population.

Perinatal and Antibiotic Exposures and the Risk of Developing Childhood-Onset Inflammatory Bowel Disease: A Nested Case-Control Study Based on a Population-Based Birth Cohort.

The role of early-life environmental exposures on Inflammatory Bowel Disease (IBD) onset remains unclear. We aimed to quantify the impact of perinatal conditions and antibiotic use in the first 6 and 12 months of life, on the risk of childhood-onset IBD, in a birth cohort of the region Friuli-Venezia Giulia (Italy). A nested case-control design on a longitudinal cohort of 213,515 newborns was adopted. Conditional binomial regression models were used to estimate Odds Ratios (OR) with 95% confidence intervals (CI) for all analyzed risk factors. We identified 164 individuals with IBD onset before the age of 18 years and 1640 controls. None of the considered perinatal conditions were associated with IBD. Analyses on antibiotic exposure were based on 70 cases and 700 controls. Risks were significantly higher for children with ≥4 antibiotic prescriptions in the first 6 and 12 months of life (OR = 6.34; 95%CI 1.68-24.02 and OR = 2.91; 95%CI 1.31-6.45, respectively). This association was present only among patients with Crohn's disease and those with earlier IBD onset. We found that perinatal characteristics were not associated to IBD, while the frequent use of antibiotics during the first year of life was associated to an increased risk of developing subsequent childhood-onset IBD.

Adherence to Disease-Modifying Therapy in Patients Hospitalized for HF: Findings from a Community-Based Study.

BACKGROUND: Much data about prescription adherence in patients with heart failure (HF) are available, but few exist about the evaluation of true patient adherence. Further, methods for analyzing this issue are poorly known. OBJECTIVES: Our objective was to evaluate the impact of patient adherence to disease-modifying drugs after HF hospitalization in a community-based cohort. METHODS AND RESULTS: Patients hospitalized with first diagnostic HF code and at least one post-discharge purchase of evidence-based drugs for HF between 2009 and 2015 were included (12,938 patients). A new method for measuring adherence to polypharmacy (patient adherence indicator [PAI]) was introduced, based on proportion of days covered (PDC) and medication possession ratio (MPR). The investigated drugs were ß-blockers (BBs), angiotensin-converting enzyme inhibitors (ACEIs), angiotensin-receptor blockers (ARBs), and anti-aldosterone agents (AAs). Regional administrative databases were analyzed. RESULTS: The mean age of the cohort was 80 years; 53% was female; the median Charlson Comorbidity Index score was 2, and the overall death rate was 60%. PAI based on PDC estimated a nonadherence rate of 47%. Median daily dosages were well below target dosages for all drugs considered. A good PAI significantly lowered the mortality risk, irrespective of the computational method used: PDC (PAI adjusted hazard ratio [HR] 0.93; 95% confidence interval [CI] 0.88-0.97; p = 0.001) or MPR (PAI adjusted HR 0.93; 95% CI 0.89-0.98; p = 0.004). CONCLUSIONS: In a real-world setting, medication adherence of patients with HF remains unsatisfactory, especially when in a polypharmacy setting. Irrespective of PDC and MPR, good patient adherence to polypharmacy was associated with a lower death rate.

Risk of bacterial pneumonia and pneumococcal infection in youths with celiac disease - A population-based study.

OBJECTIVE: Assess the risk of hospitalizations for bacterial pneumonia or pneumococcal infections, in a cohort of young individuals with celiac disease (CD) compared to matched references. STUDY DESIGN: The cohort consists of 213,635 individuals, born in 1989-2012 and resident in Friuli-Venezia Giulia (Italy). Through pathology reports, hospital discharge records or co-payment exemptions, we identified 1294 CD patients and 6470 reference individuals matched by gender and birth year. We considered hospital admissions for first episodes of bacterial pneumonia and pneumococcal infections. Hazard ratios (HRs) for episodes after CD diagnosis were calculated with Cox regression and odds ratios (OR) for the ones before CD diagnosis with conditional logistic regression. Further analyses were performed on unvaccinated follow-up periods. RESULTS: 14 CD patients (in 9450 person-years) and 42 references (in 48,335 person-years) experienced a first episode of bacterial pneumonia, with an increased risk among CD patients (HR 1.82; 95%CI 0.98-3.35). Risks of bacterial pneumonia were significantly increased before CD diagnosis and especially the year before CD diagnosis (OR 6.00, 95%CI 1.83-19.66). Risks of pneumococcal infections showed a non-significant increase in CD patients. CONCLUSIONS: CD children and youth showed an increased risk of bacterial pneumonia, especially in proximity to CD diagnosis. Anti-pneumococcal vaccination should be recommended to all young CD patients.

Thyroid cancer in Friuli Venezia Giulia, northeastern Italy: incidence, overdiagnosis, and impact of type of surgery on survival.

BACKGROUND: Incidence rates of thyroid cancer (TC) increased in the last decades worldwide. This study aimed to describe TC incidence in the Friuli Venezia Giulia (FVG) region, to estimate the quota of overdiagnosis, and to investigate the impact of surgery on long-term survival after TC diagnosis. METHODS: TC cases reported to the FVG population-based cancer registry during 2002-2013, aged <85 years, were included. Age standardized rates (ASR) on the European population were computed, while proportion of TC overdiagnosis was estimated in comparison with expected age-specific incidence rates from published time series. Adjusted hazard ratios of death, with 95% confidence intervals, were also estimated. RESULTS: During 2002-2013, 1701 TC cases were reported to the FVG cancer registry, with papillary TC (78.2%) as the most frequent histologic type. ASR increased from 12.4 to 16.5 in women and from 4.3 to 6.2 in men (+33.1% and +44.2%, respectively). Overdiagnosis was estimated as 79% of TC cases in women and 64% in men. Almost all TC cases (97.1%) underwent surgery, including 84.6% of women and 78.9% of men who underwent total thyroidectomy. Up to 10 years after TC diagnosis, the type of surgery did not appear to influence survival. CONCLUSIONS: This study documented an increase in TC incidence in FVG in the last decade, with overdiagnosis accounting for a large proportion of TC diagnoses and total thyroidectomy in more than 80% of cases. These findings suggest reconsidering thyroid screening practice and aggressive therapeutic strategies, as recommended by new TC guidelines.

Increased cancer risk in patients undergoing dialysis: a population-based cohort study in North-Eastern Italy.

BACKGROUND: In southern Europe, the risk of cancer in patients with end-stage kidney disease receiving dialysis has not been well quantified. The aim of this study was to assess the overall pattern of risk for de novo malignancies (DNMs) among dialysis patients in the Friuli Venezia Giulia region, north-eastern Italy. METHODS: A population-based cohort study among 3407 dialysis patients was conducted through a record linkage between local healthcare databases and the cancer registry (1998-2013). Person-years (PYs) were calculated from 30 days after the date of first dialysis to the date of DNM diagnosis, kidney transplant, death, last follow-up or December 31, 2013, whichever came first. The risk of DNM, as compared to the general population, was estimated using standardized incidence ratios (SIRs) and 95% confidence intervals (CIs). RESULTS: During 10,798 PYs, 357 DNMs were diagnosed in 330 dialysis patients. A higher than expected risk of 1.3-fold was found for all DNMs combined (95% CI: 1.15-1.43). The risk was particularly high in younger dialysis patients (SIR = 1.88, 95% CI: 1.42-2.45 for age 40-59 years), and it decreased with age. Moreover, significantly increased DNM risks emerged during the first 3 years since dialysis initiation, especially within the first year (SIR = 8.52, 95% CI: 6.89-10.41). Elevated excess risks were observed for kidney (SIR = 3.18; 95% CI: 2.06-4.69), skin non-melanoma (SIR = 1.81, 95% CI: 1.46-2.22), oral cavity (SIR = 2.42, 95% CI: 1.36-4.00), and Kaposi's sarcoma (SIR = 10.29, 95% CI: 1.25-37.16). CONCLUSIONS: The elevated risk for DNM herein documented suggest the need to implement a targeted approach to cancer prevention and control in dialysis patients.

Use of healthcare services at the end of life in decedents compared to their surviving counterparts: A case-control study among adults born before 1946 in Friuli Venezia Giulia.

BACKGROUND: There is a heterogeneous literature on healthcare utilization patterns at the end of life. The objective of this study is to examine the impact of closeness to death on the utilization of acute hospital-based healthcare services and some primary healthcare services and compare differences in gender, age groups and major causes of death disease specific mortality. METHODS: A matched case-control study, nested in a cohort of 411,812 subjects, linked to administrative databases was conducted. All subjects were residents in the Friuli Venezia Giulia Region (Italy), born before 1946, alive in January 2000 and were followed up to December 2014. Overall, 158,571 decedents/cases were matched by gender and year of birth to one control, alive at least one year after their matched case's death (index-date). Hospital admissions, emergency department visits, drug prescriptions, specialist visits and laboratory tests that occurred 365 days before death/index-date, have been evaluated. Odds Ratios (ORs) for healthcare utilization were estimated through conditional regression models, further adjusted for Charlson Comorbidity Index and stratified by gender, age groups and major causes of death. RESULTS: Decedents were significantly more likely of having at least one hospital admission (OR 7.0, 6.9-7.1), emergency department visit (OR 5.2, 5.1-5.3), drug prescription (OR 2.8, 2.7-2.9), specialist visit (OR 1.4, 1.4-1.4) and laboratory test (OR 2.7, 2.6-2.7) than their matched surviving counterparts. The ORs were generally lower in the oldest age group (95+) than in the youngest (55-74). Healthcare utilization did not vary by sex, but was higher in subjects who died of cancer. CONCLUSION: Closeness to death appeared to be strongly associated with healthcare utilization in adult/elderly subjects. The risk seems to be greater among younger age groups than older ones, especially for acute based services. Reducing acute healthcare at the EOL represents an important issue to improve the quality of life in proximity to death.

The Role of Maternal Citizenship on Pediatric Avoidable Hospitalization: A Birth Cohort Study in North-East Italy.

OBJECTIVE: Avoidable hospitalization (AH) has been widely studied as a possible measure of primary health care performance. Since studies evaluating AH in migrant children, particularly in Europe, are lacking, the aim of this study was to investigate the role of maternal citizenship on the risk of AH in children. METHODS: The cohort study included all live newborns recorded in the Medical Birth Register (MBR) of Friuli-Venezia Giulia Region (Italy) in the years 1989-2012, followed from 30 d after their birth up to the 14th year of life. Cox regression models were used to estimate Hazard Ratios (HRs) for any AH and for specific conditions. RESULTS: Among the 213,635 children included in the cohort, authors identified 23,011 AHs in 16,744 children, most of which occurred between 1 and 4 y of age. Children born to mothers from High Migration Pressure Countries had a higher risk of AH for any condition (HR 1.35; 95% CI = 1.27-1.44) than children born to Italian mothers. The risks were higher concerning gastroenteritis (HR 1.74; 1.57-1.94), upper respiratory tract infections (HR 1.58; 1.35-1.84), asthma (HR 1.53; 1.12-2.06) and bacterial pneumonia (HR 1.18; 1.01-1.37). There were no differences in urinary tract infections, short term complications of diabetes and perforated appendix. CONCLUSIONS: Despite the inclusiveness and universality of the Italian healthcare system, children born to immigrant mothers experienced more need of avoidable hospital care than children born to Italian mothers. Access barriers to primary care are plausible causes for the observed disparities.

Risk of serious infection among patients receiving biologics for chronic inflammatory diseases: Usefulness of administrative data.

Risk of hospitalized infections under biologics among patients suffering from chronic inflammatory autoimmune diseases such as rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PSA), or psoriasis was investigated using administrative data. The hospital discharge records database, the medical prescription database, and the database of exemptions from medical charges were linked at the individual patient level. A cohort of patients diagnosed with RA, SA, PSA, and severe psoriasis from 2006 to 2017 was identified and followed-up to either the end of 2017 or hospitalization with the main discharge diagnosis of infection, death, or they moved out of the region. Multiple Cox regression was used to estimate the hazard ratio (HR) of hospitalization associated with bDMARDs and adjusting for age, sex, Charlson's Comorbidity Index, calendar year, prescription of steroids, and use of csDMARDs. Use of bDMARDs was treated as a time-dependent variable. A total of 5596 patients diagnosed with RA, AS, or PSA/severe psoriasis were included in the cohort. Overall, 289 (4.2%) were hospitalized due to infection. Time to first use of biological drugs was significantly associated with a 55% increased risk of hospitalization for infections. Thus, large cohorts from administrative databases are useful to support observations from registries and clinical trials. Patients with chronic autoimmune inflammatory diseases are at risk of serious infections when starting biologics. This risk is higher in the elderly or those with comorbidities. Upper and lower respiratory tract infections are the most common infections. Our findings support prevention policies such as vaccination.

Risk of Fractures in Youths with Celiac Disease-A Population-Based Study.

OBJECTIVE: To assess the risk of any fracture requiring hospital care in a cohort of individuals with celiac disease diagnosed in childhood/adolescence compared with reference individuals matched by age and sex. STUDY DESIGN: Our study cohort consisted of 213 635 people born and residing in Friuli-Venezia Giulia Region, Italy, in 1989-2011. We selected, through pathology reports, hospital discharge records, or co-payment exemptions, 1233 individuals with celiac disease (aged 0-17 years at diagnosis) and compared them with 6167 reference individuals matched by sex and year of birth. Fractures were identified through hospital discharge records. We calculated hazard ratios (HRs) for any fracture after celiac disease diagnosis (or index date for reference individuals) with Cox regression and ORs for any fracture before celiac disease diagnosis with conditional logistic regression. RESULTS: During the follow-up period (maximum 23 years), 22 individuals with celiac disease (9394 person-years) and 128 reference individuals (47 308 person-years) experienced a fracture, giving an overall HR of 0.87 (95% CI 0.55-1.37). The risk was not modified by sex, age at diagnosis, or calendar period of diagnosis. We obtained similar HRs when excluding fractures occurring after the age of 18 years and adjusting for maternal education or vitamin D supplementation. The odds of previous fracture also did not differ between subjects with celiac disease and reference individuals (22 and 96 cases, respectively: OR 1.15; 95% CI 0.72-1.84). CONCLUSIONS: We did not find any evidence of an increased risk of fractures during childhood and youth among patients with celiac disease.

Inflammatory Bowel Diseases in Children and Young Adults with Celiac Disease. A Multigroup Matched Comparison.

BACKGROUND: Celiac disease (CD) has been linked to inflammatory bowel disease (IBD) but previous reports have been inconsistent and may have been affected by surveillance bias. METHODS: Matched birth cohort study in Friuli-Venezia Giulia Region, Italy. We identified 1294 individuals with CD aged 0 to 23 years at diagnosis using pathology reports, hospital discharge records, or copayment exemptions. Each CD individual was matched with up to 5 general population reference individuals from the regional Medical Birth Register in Friuli-Venezia Giulia (n = 5681). As secondary comparison groups, we used individuals undergoing small intestinal biopsy but not having villous atrophy (either Marsh 0-1-2 or exclusively Marsh 0). Individuals with IBD were identified through hospital discharge records or copayment exemptions. Conditional logistic regression was used to estimate odds ratios (ORs) for having IBD among CD individuals (before or after CD diagnosis) compared with their matched references. RESULTS: Overall 35 individuals with IBD were identified (29 with CD and 6 general population controls). This corresponded to an increased risk of IBD in CD (OR = 24.17; 95% CI, 10.03-58.21). However, compared with individuals with Marsh 0-1-2 the OR decreased to 1.41 (95% CI, 0.91-2.18) and restricting our comparison group to individuals with Marsh 0, the OR was 1.28 (95% CI, 0.61-2.70). CONCLUSIONS: In conclusion, this article found a highly increased risk of IBD in individuals with CD when comparing with the general population. Bias is the likely explanation for the very high risk increase for IBD in CD because the excess risk was substantially lower when we used individuals with a small intestinal biopsy without villous atrophy as our reference.

Residence in Proximity of a Coal-Oil-Fired Thermal Power Plant and Risk of Lung and Bladder Cancer in North-Eastern Italy. A Population-Based Study: 1995-2009.

This study investigated the risk of lung and bladder cancers in people residing in proximity of a coal-oil-fired thermal power plant in an area of north-eastern Italy, covered by a population-based cancer registry. Incidence rate ratios (IRR) by sex, age, and histology were computed according to tertiles of residential exposure to benzene, nitrogen dioxide (NO2), particular matter, and sulfur dioxide (SO2) among 1076 incident cases of lung and 650 cases of bladder cancers. In men of all ages and in women under 75 years of age, no significant associations were observed. Conversely, in women aged ≥75 years significantly increased risks of lung and bladder cancers were related to high exposure to benzene (IRR for highest vs. lowest tertile: 2.00 for lung cancer and 1.94 for bladder cancer) and NO2 (IRR: 1.72 for lung cancer; and 1.94 for bladder cancer). In these women, a 1.71-fold higher risk of lung cancer was also related to a high exposure to SO2. Acknowledging the limitations of our study, in particular that we did not have information regarding cigarette smoking habits, the findings of this study indicate that air pollution exposure may have had a role with regard to the risk of lung and bladder cancers limited to women aged ≥75 years. Such increased risk warrants further analytical investigations.

Celiac Disease and Risk of Autoimmune Disorders: A Population-Based Matched Birth Cohort Study.

OBJECTIVES: To estimate the relative risk of developing type 1 diabetes mellitus (T1DM) and autoimmune thyroid disease in children with celiac disease (CD). STUDY DESIGN: A matched cohort design with linkage of administrative data was adopted. A total of 1215 cases of CD and 6075 references matched by sex and year of birth born in Friuli Venezia Giulia Region (Italy) between 1989 and 2011 were included. Cox regression models were used to estimate hazard ratios (HRs) for autoimmune diseases in patients with CD compared with references, stratified by sex and age at diagnosis. RESULTS: Individuals with CD had an increased risk of subsequent hypothyroidism (HR 4.64 [95% CI 2.88-7.46]) and T1DM (HR 2.50 [95% CI 0.94-6.66]), the latter not statistically significant. Risk of hypothyroidism was higher in males (HR 20.00; 95% CI 5.64-70.87) than females (HR 3.21; 95% CI 1.85-5.57) (P value <.01). No differences were observed between males and females risks for diabetes or age at CD diagnosis. The small number of hyperthyroidism cases identified precluded any statistical analysis. CONCLUSIONS: Children and youth with CD are at increased risk of developing autoimmune hypothyroidism and to some extent T1DM. This suggests the need for surveillance of children with CD in order to timely detect the onset of such comorbidities.

The incidence rate and prevalence of pediatric type 1 diabetes mellitus (age 0-18) in the Italian region Friuli Venezia Giulia: population-based estimates through the analysis of health administrative databases.

AIMS: The main objective of this study was to estimate the incidence rate and prevalence of pediatric type 1 diabetes mellitus (T1DM; population 0-18 years of age) in the northeastern Italian region Friuli Venezia Giulia and to characterize the subjects affected by the disease. METHODS: This was a retrospective population-based study conducted through the individual-level linkage of several health administrative databases of the Friuli Venezia Giulia region. The incidence rate and prevalence were calculated in the population 0-18 years of age. Using the Mid-p exact method, 95 % confidence intervals for rates were calculated. RESULTS: The incidence rate of pediatric T1DM in the years 2010-2013 was 15.8 new cases/100,000 person-years, peaking in the age class 10-14 years. The rate has increased substantially as compared with the previous regional estimate that dated back to 1993. We observed a seasonal pattern both in the date of birth of the incident cases and in the date of onset of the disease. In the region in 2013, there were 294 prevalent cases (15.1/10,000 inhabitants). Most of them had at least one glycated hemoglobin test in the year. More than 15 % had co-existing autoimmune comorbidities. CONCLUSIONS: The incidence rate of pediatric T1DM in Friuli Venezia Giulia has increased in the last years, and the disease is a relevant public health issue in the region.

Cancer among patients with type 2 diabetes mellitus: A population-based cohort study in northeastern Italy.

Diabetes mellitus (DM) is associated with an elevated risk of cancer. The aim of this study was to assess cancer risk and survival in individuals with type 2 DM (T2DM) in Friuli Venezia Giulia, Italy. A retrospective population-based cohort study of 32,247 T2DM patients aged 40-84 years was conducted through a record linkage of local healthcare databases and cancer registry for the period 2002-2009. Standardized incidence ratios (SIRs) with 95% confidence intervals (95%CIs) and 5-year survival probabilities after T2DM and cancer diagnosis were computed. The SIRs for all cancers (n=2069) was 1.28 (95%CI: 1.23-1.34). The highest SIRs were observed for cancers of the liver, female genital organs, small intestine, and pancreas. After 3 years from T2DM diagnosis, a reduced risk of prostate cancer (SIR=0.73, 95%CI: 0.54-0.96) was found in men aged 65-74 years, and a higher risk for breast cancer (SIR=1.24, 95%CI: 1.00-1.52) was found among T2DM female patients. The overall 5-year survival after T2DM was 88.7%. Furthermore, T2DM appeared to have a negative effect on survival of women with breast cancer. This population-based study confirmed that T2DM patients are at increased risk of several cancers, and of premature death in women with breast cancer.
