Background Non-natural mortality in children and adolescents is a global public health problem that varies widely from country to country. Data on child and adolescent maltreatment are not readily available, and mortality due to violent causes is also underestimated. Methods Injury-related mortality rates (overall and by specific causes) from 2000 to 2018 in selected European countries were analysed to observe mortality patterns in children and adolescents using data from the Eurostat database. Age-standardized mortality rates per 100,000 person-years were calculated for each country. Joinpoint regression analysis with a significance level of 0.05 and 95% confidence intervals was performed for mortality trends. Results Children and adolescent mortality from non-natural causes decreased significantly in Europe from 10.48 around 2005 to 5.91 around 2015. The Eastern countries (Romania, Bulgaria, Poland, Slovakia, Czech Republic) had higher rates; while Spain, Denmark, Italy, and the United Kingdom had the lowest. Rates for European Country declined by 5.10% per year over the entire period. Larger downward trends were observed in Ireland, Spain and Portugal; smaller downward trends were observed for Eastern countries (Bulgaria, Czech Republic, Poland, Slovakia) and Finland. Among specific causes of death, the largest decreases were observed for accidental causes (-5.9%) and traffic accidents (-6.8%). Conclusions Mortality among children and adolescents due to non-natural causes has decreased significantly over the past two decades. Accidental events and transport accidents recorded the greatest decline in mortality rates, although there are still some European countries where the number of deaths among children and adolescents from non-natural causes is high. Social, cultural, and health-related reasons may explain the observed differences between countries. Key Messages • The mortality of children and adolescents due to non-natural causes has decreased significantly in the last two decades; • Substantial differences between countries were found in the trend of non-natural causes of death in children and adolescents; • Accidental events and transport accidents showed the greatest decrease in mortality; • In some European countries, there is still a high number of deaths in children and adolescents that are due to non-natural causes;

ObjectiveIn Italy, the first diagnosis of COVID-19 was confirmed on 20 February 2020 in the Lombardy region. Given the rapid spread of the infection in the population, it was suggested that in Europe, and specifically in Italy, the virus had already been present in the last months of 2019. In this paper, we aim to evaluate the hypothesis on the early presence of the virus in Italy by analysing data on trends of access to emergency departments (EDs) of subjects with a diagnosis of pneumonia during the 2015–2020 period.DesignTime series cohort study.SettingWe collected data on visits due to pneumonia between 1 October 2015 and 31 May 2020 in all EDs of the Agency for Health Protection of Milan (ATS of Milan). Trend in the winter of 2019–2020 was compared with those in the previous 4 years in order to identify unexpected signals potentially associated with the occurrence of the pandemic. Aggregated data were analysed using a Poisson regression model adjusted for seasonality and influenza outbreaks.Primary outcome measures Daily pneumonia-related visits in EDs.Results In the studied period, we observed 105 651 pneumonia-related ED visits. Compared with the expected, a lower occurrence was observed in January 2020, while an excess of pneumonia visits started in the province of Lodi on 21 February 2020, and almost 10 days later was observed in the remaining territory of the ATS of Milan. Overall, the peak in excess was found on 17 March 2020 (369 excess visits compared with previous years, 95% CI 353 to 383) and ended in May 2020, the administrative end of the Italian lockdown.Conclusions An early warning system based on routinely collected administrative data could be a feasible and low-cost strategy to monitor the actual situation of the virus spread both at local and national levels.

(1) Background: Several studies have reported associations between maternal diet in terms of single foods or nutrients and human milk compounds, while the overall role of maternal diet and related dietary patterns has rarely been investigated. (2) Methods: Between 2012 and 2014, we enrolled 300 healthy Italian mothers, who exclusively breastfed their infant. During a hospital visit at 6 weeks postpartum, a sample of freshly expressed foremilk was collected and information on maternal dietary habits in the postpartum period was obtained through an interviewer-administered food frequency questionnaire. We applied principal component factor analysis to selected nutrients in order to identify maternal dietary patterns, and assessed correlations in human milk macronutrients and fatty acids across levels of dietary patterns. (3) Results: Five dietary patterns were identified, named “Vitamins, minerals and fibre”, “Proteins and fatty acids with legs”, “Fatty acids with fins”, “Fatty acids with leaves”, “Starch and vegetable proteins”. These dietary patterns were correlated with some milk components, namely fatty acids, and in particular ω-3 and its subcomponents. (4) Conclusions: This study showed that overall maternal dietary habits during breastfeeding may influence human milk composition, suggesting the importance of adequate maternal nutrition during lactation not only for the mother herself but also to provide the infant with milk containing adequate amount and quality of nutrients for a balanced nutrition.

Breast cancer is the most common cancer diagnosis and the leading cause of cancer death among women in the world, and differences across populations indicate a role of hormonal, reproductive and lifestyle factors. This study is based on a cohort of 78,050 women invited to undergo a mammogram by Local Health Authority of Milan, between 2003 and 2007. We carried out a nested case–control study including all the 3303 incident breast cancer cases diagnosed up to 2015, and 9909 controls matched by age and year of enrollment. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were estimated using logistic regression models. The ORs were 0.88 (95% CI: 0.78–0.98) for an age at menarche ≥14 years and 1.39 (95% CI: 1.07–1.81) for an age of 30 years or older at first pregnancy. Body mass index (BMI) was positively associated with breast cancer risk in women older than 50 years (OR = 1.89, 95% CI: 1.54–2.31, for BMI≥30 vs. <20), while the association tended to be inverse in younger women. A high mammographic density increased breast cancer risk (OR = 2.61, 95% CI: 2.02–3.38 for density >75% vs. adipose tissue). The ORs were 1.67 (95% CI: 1.47–1.89) and 2.04 (95% CI: 1.38–3.00) for one first‐degree relative and two or more relatives affected by breast cancer, respectively. Our study confirms the role of major recognized risk factors for breast cancer in our population and provides the basis for a stratification of the participants in the mammographic screening according to different levels of risk. This study is based on a uniquely large Italian cohort of participants of mammographic screening program and investigated several risk factors. Late menarche, and an early age at first pregnancy protected against breast cancer. A higher mammographic density, family history of breast cancer, and a higher body weight (in postmenopause) increased breast cancer risk. Our study provides the basis for a stratification of participants in the mammographic screening according to different levels of risk.

Background/objectives To assess the association between processed meat and the risk of selected digestive tract and laryngeal cancers. Subjects/methods We conducted a series of case-control studies between 1985 and 2007 in Italy. The studies included a total of 1475 cases of cancer of the oral cavity and pharynx, 1077 of the larynx, 716 of the esophagus, 999 of the stomach, 684 of the liver, 159 of the biliary tract, 688 of the pancreas, and a total of 9720 controls. Odds ratios (ORs), and the corresponding 95% confidence intervals (CIs), were estimated by unconditional logistic regression models, including terms for socio-demographic factors, tobacco smoking, and alcohol intake. Results Compared to the lowest tertile of processed meat consumption, the ORs for subjects in the highest one were 1.18 (95% CI 0.98–1.43) for oral cavity and pharyngeal, 1.51 (95% CI 1.18–1.91) for esophageal, 1.19 (95% CI 0.96–1.47) for laryngeal, 0.98 (95% CI 0.81–1.18) for stomach, 0.85 (95% CI 0.51–1.40) for biliary tract, 1.20 (95% CI 0.94–1.54) for liver, and 1.46 (95% CI 1.15–1.85) for pancreatic cancers. Conclusions Our findings support the hypothesis that high processed meat consumption increases esophageal and pancreatic cancers risk. Residual confounding by socio-demographic factors, tobacco smoking, and alcohol intake may, partly or largely, account for these associations. We found no overall association with other digestive tract and laryngeal cancers.

Evidence from COVID-19 outbreak shows that individuals with specific chronic diseases are at higher risk of severe prognosis after infection. Public health authorities are developing vaccination programmes with priorities that minimize the risk of mortality and severe events in individuals and communities. We propose an evidence-based strategy that targets the frailest subjects whose timely vaccination is likely to minimize future deaths and preserve the resilience of the health service by preventing infections. The cohort includes 146,087 cases with COVID-19 diagnosed in 2020 in Milan (3.49 million inhabitants). Individual level data on 42 chronic diseases and vital status updated as of January 21, 2021, were available in administrative data. Analyses were performed in three sub-cohorts of age (16–64, 65–79 and 80+ years) and comorbidities affecting mortality were selected by means of LASSO cross-validated conditional logistic regression. Simplified models based on previous results identified high-risk categories worth targeting with highest priority. Results adjusted by age and gender, were reported in terms of odds ratios and 95%CI. The final models include as predictors of mortality (7,667 deaths, 5.2%) 10, 12, and 5 chronic diseases, respectively. The older age categories shared, as risk factors, chronic renal failure, chronic heart failure, cerebrovascular disease, Parkinson disease and psychiatric diseases. In the younger age category, predictors included neoplasm, organ transplantation and psychiatric conditions. Results were consistent with those obtained on mortality at 60 days from diagnosis (6,968 deaths). This approach defines a two-level stratification for priorities in the vaccination that can easily be applied by health authorities, eventually adapted to local results in terms of number and types of comorbidities, and rapidly updated with current data. After the early phase of vaccination, data on effectiveness and safety will give the opportunity to revise prioritization and discuss the future approach in the remaining population.

•Data is based on a hospital-based case–control study on endometrial cancer.•We carried out a principal component factor analysis on 28 nutrients.•We identified five major dietary patterns.•Dietary patterns high in animal products were at increased risk for endometrial cancer. Diet has been suggested to have a role on endometrial cancer risk, but few data are available on the role of dietary patterns on this neoplasm. A case–control study was carried out in Italy, including 454 women with endometrial cancer and 908 hospital controls admitted to the same hospitals for acute, non-neoplastic diseases. Dietary information was based on a reproducible and valid food frequency questionnaire. A posteriori dietary patterns were obtained using principal component factor analysis on 28 nutrients. Odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) were obtained from multiple logistic regression models conditioned on age and study center, and adjusted for major known confounding factors. Positive associations were found for the “Western-type diet” (OR=1.63, 95% CI: 1.12–2.38, for the highest versus the lowest quartile category) and the “Animal-derived nutrients and polyunsaturated fatty acids” patterns (OR=1.76, 95% CI: 1.23–2.52). The corresponding risk estimates among women with a body mass index ≥30 were 2.08 (95% CI: 0.92–4.69) and 2.30 (95% CI: 1.03–5.16) for the two patterns, respectively. No association was found for the other three patterns (i.e., “Vitamins and fiber”, OR=0.96, 95% CI: 0.67–1.37, “Starch-rich”, OR=0.99, 95% CI: 0.69–1.42, and “Other fats”, OR=1.03, 95% CI: 0.70–1.52). This study indicates that dietary habits characterized by high intakes of animal products increase endometrial cancer risk, the association being appreciably stronger for obese women.

Forensic autopsy is an important tool for the proper management of non-natural deaths in minors. However, it seems that autopsy in minors is a practice which may not be performed routinely. In this framework, we conducted a study analyzing autopsies of minors (under 18 years of age in Italy) performed at the Institute of Forensic Medicine in Milan in the period 2001–2019. For the period 2015–2019, we extrapolated all deaths due to non-natural causes in minors to investigate how many and which of these deaths were not subjected to forensic autopsy. Of the total, 344 minors (235 males and 109 females) underwent autopsies, with an overall downward trend of about 80% since 2004. Most autopsies occurred between the ages of 0 and 1 year, and the fewest between the ages of 5 and 9 years. The place of death was home in most cases, and accidental death was most common, followed by natural death, suicide, and homicide, with prevalence varying by age group. Blunt force trauma predominated among accidental death in all age groups, followed by asphyxia. Similar findings were observed for suicides, although there was a more differentiated pattern for suicides between the ages of 15 and 17 years. Among homicides, blunt force trauma, asphyxia, and gunshot wounds were fairly evenly distributed across all age groups. Between 2015 and 2019, a total of 86 minors died of a non-natural cause, and a forensic autopsy was performed in only 33 cases (38%). Our data shows that fewer and fewer autopsies are being performed over the last years, which indicates a dangerous lack of forensic investigation of children and adolescent deaths, with enormous implications for prevention of child abuse.

•We found positive associations between processed meat and selected female cancers.•The association was less strong in more recent data as a result of better covariate adjustment.•We found no association with cancer of the prostate.•Limited processed meat intake may be part of the Mediterranean diet pattern. To assess and quantify the association between processed meat consumption and cancers of the breast, endometrium, ovary, and prostate. Data were derived from an integrated network of hospital-based case-control studies conducted between 1982 and 2006 in various Italian areas. These studies included 5981 cases of cancer of the breast, 992 of the endometrium, 2002 of the ovary, 1582 of the prostate, and a total of 16 394 controls with data on processed meat. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by unconditional multiple logistic regression models, adjusted for major recognized confounders for each cancer site. The median consumption of processed meat in this population was 2 portions per wk in each cancer-specific cases, controls, and overall, corresponding to 100 g/wk. The OR for the highest (≥20 g/d) compared with lowest (<10 g/d) category of processed meat consumption was 1.16 (95% CI 1.06–1.28) for breast, 1.31 (95% CI 1.07–1.60) for endometrial, 1.49 (95% CI 1.30–1.71) for ovarian, and 0.89 (95% CI 0.74–1.07) for prostate cancer. In this case-control study, we found some excess risks of high processed meat consumption with female hormone-related cancers. Conversely, no association with prostate cancer was found in men.

Purpose Few studies investigated the role of diet on nasopharyngeal cancer (NPC) risk in non-endemic areas. The aim of this study was to assess the association between adherence to the traditional Mediterranean diet and NPC risk in a southern European low-risk population. Methods We conducted a hospital-based case-control study in Italy, including 198 histologically confirmed NPC cases and 594 matched controls. Dietary habits were collected by means of a validated food-frequency questionnaire, including 83 foods, food groups, or beverages. Adherence to the traditional Mediterranean diet was assessed through a Mediterranean Diet Score (MDS), based on nine dietary components characterizing this dietary profile, i.e., high intake of vegetables, fruits and nuts, cereals, legumes, and fish; low intake of dairy products and meat; high monounsaturated to saturated fatty acid ratio; and moderate alcohol intake. We estimated odds ratios (ORs) of NPC, and the corresponding 95% confidence intervals (CIs), for increasing MDS (i.e., increasing adherence) using multiple logistic regression models, adjusted for major confounding factors. Results As compared to MDS ≤ 4, the ORs of NPC were 0.83 (95% CI: 0.54–1.25) for MDS of 5 and 0.66 (95% CI: 0.44–0.99) for MDS ≥ 6, with a significant trend of decreasing risk (p 0.043). The corresponding population attributable fraction was 22%, indicating that 22% of NPC cases in this population would be avoided by shifting all subjects to a score ≥6. Conclusions Our study supports a favorable role of the Mediterranean diet on NPC risk.
