Incidence of apparent life-threatening events and post-neonatal risk factors.

AIM: Even though a standard clinical definition for an apparent life-threatening event (ALTE) was established more than two decades ago, the specific International Classification of Disease (ICD) code was firstly included only in 2012. This study estimated the incidence of ALTEs in Northern Italy, together with features and risk factors. METHODS: We used the Lombardy Region Hospital Discharge Records (HDR) database to estimate the cumulative incidence for ALTE during 2002-2006 and drew up a risk profile by comparing cases with and without ALTE who were followed in infancy. RESULTS: There were 246 infants registered in the HDR with ALTE putative diagnostic codes, suggesting a cumulative incidence of 4.1 per 1000 live births in the study area. Of the 148 cases with clinical co-morbidities, 31% had gastroesophageal reflux and 7% had acute respiratory infections. We analysed follow-up data from 15 ALTE cases and 1619 healthy infants and found that the significant risk factors were gastroesophageal reflux and a family history of sudden death. CONCLUSION: We established the regional incidence of ALTE and found risk factors in infants considered healthy in the first week of life and without pathological perinatal conditions. The systematic use of the specific ALTE ICD code (R68.13, ICD-10-CM) and common knowledge about ALTE diagnostic guidelines are clearly needed.

[A method for identifying people with a high level of frailty by using a population database, Varese, Italy]. / Un metodo per identificare pazienti ad alto grado di fragilità a partire dalla Banca Dati Assistiti nell'ASL di Varese.

Since over 10 years, the Lombardy Region (Italy) has developed a system for classifying all persons registered with the healthcare system (database of persons registered with a general practitioner), according to their use of major healthcare services (hospitalizations, outpatient consultations, pharmaceutical) and whether they are exempt from copayment fees for disease-specific medications and healthcare services. The present study was conducted by the local health authorities of the province of Varese (Lombardy region, Italy) with 894.039 persons registered in the database of whom 258.770 (28.9%) with at least one chronic condition, 104.731 (11.7%) with multiple chronic conditions and 195.296 (21.8%) elderly persons. The aim was to evaluate death rates in different subgroups of patients entered in the database, including persons with chronic diseases and elderly persons. Standardized mortality rates were calculated for the year 2012. Compared with the general population, relative risk for mortality was 4,1 (95% confidence Intervals 4,0-4,2) in the elderly and 1,3 (95% confidence intervals 1,3-1,4) in chronic patients. This confirms that elderly persons have a higher level of frailty with respect to patients with chronic conditions. Mortality was found to be 28 times higher in elderly persons over 74 years of age, affected by high cost conditions such as cancer and cardiac disease, with respect to the general population.

Assessment of mortality risk in elderly patients after proximal femoral fracture.

Mortality after hip fracture is a major problem in the Western world, but its mechanisms remain uncertain. This study assessed the 2-year mortality rate after hip fracture in elderly patients by including hospital factors (eg, intervention type, surgical delay), underlying health conditions, and, for a subset, lifestyle factors (eg, body mass index, smoking, alcohol). A total of 828 patients (183 men) 70 to 99 years old experiencing a hip fracture in 2009 in the province of Varese were included in the study. The risk factors for death were assessed through Kaplan-Meier analysis and Cox proportional hazards analysis. Hip fracture incidence per 1000 persons was higher in women (8.4 vs 3.7 in men) and in elderly patients (12.4 for 85-99 years vs 4.4 for 70-84 years). The mortality rate after 1, 6, 12, and 24 months was 4.7%, 16%, 20.7%, and 30.4%, respectively. For the province of Varese, sex (hazard ratio, 0.39 for women), age group (hazard ratio, 2.2 for 85-99 years), and Charlson Comorbidity Index score (hazard ratio, 2.06 for score greater than 1) were found to be statistically significant. The 2-year mortality rate in hip fractures is associated with sex, age, and comorbidities. Male sex, age older than 85 years, and Charlson Comorbidity Index score greater than 1 are associated with a higher risk. Surgical delay was significant in the Kaplan-Meier survival time analysis but not in the Cox hazard analysis, suggesting that early surgery reduces risk in patients with numerous comorbidities.

[Descriptive study of cancer incidence in the area around the Ispra Joint Research Centre (JCR)]. / Studio descrittivo sull'incidenza di tumori maligni nell'area circostante al Centro comune di ricerca (CCR) di Ispra.

OBJECTIVE: to assess the effects of radioactive emissions from the EU Joint Research Centre (JRC) (nuclear) at Ispra, the Local Health Authority (ASL) of Varese carried out an ecological study to measure any excess incidence of cancer in the surrounding population. DESIGN AND SETTING: after estimation of historical exposure levels in the surrounding population, the incidence rates of leukaemia and other exposure-related tumours were calculated from data in the population based Lombardy Cancer Registry (Varese Province). By indirect standardization, the expected cases (based on incidence rate in the Province) were compared with observed cases in the close-by municipality of Ispra, in municipalities within a 5 km radius of the JRC (5kmArea) and in the area covered by the District of Sesto Calende (DistrictArea). RESULTS: in the period 1982-1998, mean populations were 4,687 (Ispra), 32,120 (5kmArea) and 43,707 (DistrictArea); the population of the Province was 793,752. The numbers of cancers registered were 374, 2,920, 4,099 and 72,246 respectively. Significant excesses of leukaemia were not found in Ispra (SIR 0.33, 95% CI 0.07-0.96) or the 5kmArea (SIR 0.83, 95% CI 0.63-1.08). For all cancers combined and for the commonest cancers (breast, colo-rectal) the numbers of incident cases were lower than expected. CONCLUSIONS: consistent with the low levels of exposure detected, and despite the fears of the local people, no incidence excesses of cancers was found in Ispra, the town closest to the JRC, or inforin the surrounding areas. It may be worth searching for excess cancer among exposed workers.

[Use of healthcare services by elderly people in a local health authority in Varese (Italy)]. / I consumi di prestazioni sanitarie negli anziani dell'ASL della provincia di Varese.

Older people use more healthcare than younger people and aging of the population is considered to be one of the main factors leading to consumption of healthcare resources. The aim of this study was to evaluate rates of hospitalization, use of out-patient services and medicine confections among the elderly population (>65 years) in the local health authority of Varese (Italy), in the three-year period from 2003-2005, and to calculate the trend for the years 2006 and 2007. Rates of hospitalization and drug use remained stable while use of out-patient services showed an increasing trend. In spite of the influence of aging on consumption of healthcare resources, the use of medical services is determined mainly by the health state of the population: monitoring of the burden of morbidity in the population should therefore be improved.

[Epidemiologic study Salus domestica: evaluation of health damage in a sample of women living near the Malpensa 2000 airport]. / Studio epidemiologico Salus domestica: valutazione dei danni di salute in un campione di donne residenti nei pressi dell'aeroporto Malpensa 2000.

The opening of the new Malpensa 2000 Airport worried people living in the neighbouring towns about possible effects of acoustic and air pollution on health status. For this reason, Varese Health Unit set up a study involving housewives and General Practitioners. This study has been carried out in 3 Areas: A Area, bordering the airport, B Area, at intermediate distance, and C Area, at long distance. On the whole, 932 housewives (18 to 64 years old) and 92 General Practitioners, were involved. The questionnaire, distributed to housewives between May 1st and November 30th 2000, was filled out in the doctor's surgery who furthermore added clinical data. Chi-square statistics were calculated to test the association between living area and personal data, behavioural and environmental characteristics, and reported disorders. To describe possible interrelationships between living Area and the answers supplied by housewives and General Practitioners the multiple correspondence multivariate analysis technique was applied. The housewives living next to the airport (A area) frequently report insomnia, nocturnal waking, anxiety and difficulty in hearing words. The multivariate analysis has shown a relationship between recently increasing noise noted by the housewives, and the area where they live, as well as a noticeable coherence between the answers given by the housewives and those given by the General Practitioners, who reported higher frequencies of cephalgy, allergies, anxiety neurosis, medical consultation, benzodiazepine's and sleeping disorder's prescriptions in A Area compared to C Area. The airport's presence seems to be associated with the onset of subjective disorders in neighbouring population. Some of these disorders, in particular neuropsychological ones, are clinically confirmed by General Practitioners, and are consistent with different noise exposure levels.
