BackgroundThe prevalence of myopia is increasing worldwide. The purpose of this study was to evaluate the progression of myopia in teenagers and adults in France.MethodsThis nationwide prospective study followed 630 487 myopic adults and teenagers (mean age 43.4 years±18.2, 59.8% of women) between January 2013 and January 2019. Myopia and high myopia were defined as a spherical equivalent less than or equal to –0.50 and –6.00 diopters (D), respectively. Demographic data were collected at first visit and refractive characteristics were collected at each visit. Analysis of short-term progression (first 12 to 26 months postbaseline) was modelled using analysis of variance (ANOVA). Progression of myopia was stratified according to age, gender and spherical equivalent at first visit.ResultsHigher proportions of progressors were observed in the youngest age groups: 14–15 (18.2 %) and 16–17 years old (13.9 %). In multivariate analysis, after adjustment for over age, spherical equivalent and gender, the mean short-term progression decreased from –0.36 D in the 14–15 years age group to –0.13 D in the 28–29 years age group. Young age and higher myopia at baseline together were strongly associated with the risk of developing high myopia, the 5-year cumulative risk being 76% for youngest teenager with higher myopia status at baseline.ConclusionIn this large cohort of myopic teenagers and adults, myopia progression was reported in 18.2% and 13.9% of the 14–15 and 16–17 age groups, respectively. The risk to develop high myopia was higher for younger individuals with higher myopia at baseline examination.

PurposeData on myopia progression during its entire course are scarce. The aim of this study is to investigate myopia progression in Europeans as a function of age and degree of myopia from first prescription to final refractive error.MethodsThe Drentse Refractive Error and Myopia Study assessed data from a branch of opticians in the Netherlands from 1985 onwards in a retrospective study. First pair of glasses prescribed was defined as a spherical equivalent of refraction (SER) ≤−0.5 D to ≥−3.0 D. Subjects with prescriptions at an interval of at least 1 year were included in the analysis.ResultsA total of 2555 persons (57.3% female) met the inclusion criteria. Those with first prescription before the age of 10 years showed the strongest progression (−0.50 D; IQR: −0.75 to −0.19) and a significantly (p<0.001) more negative median final SER (−4.48 D; IQR: −5.37 to −3.42). All children who developed SER ≤−3 D at 10 years were highly myopic (SER ≤−6D) as adults, children who had SER between −1.5 D and −3 D at 10 years had 46.0% risk of high myopia, and children with SER between −0.5 D and −1.5 D had 32.6% risk of high myopia. Myopia progression diminished with age; all refractive categories stabilised after age 15 years except for SER ≤−5 D who progressed up to −0.25 D annually until age 21 years.ConclusionOur trajectories of the natural course of myopia progression may serve as a guide for myopia management in European children. SER at 10 years is an important prognostic indicator and will help determine treatment intensity.

Background/Aim. In studies that investigate the health effects of short-term air pollution exposure, population-wide changes in acute outcomes such as mortality, hospital admissions and healthcare visits are linked to short-term variations in ambient pollutant concentrations. The aim of this study was to estimate the association between daily outdoor black smoke and sulphur dioxide levels and hospital admissions for cardiovascular and respiratory diseases in Nis, within a period 2001-2005. Methods. A time series analysis was performed using separated regression models for each pollutant and disease group, by age groups and population as a whole. The effects of copollutant, meteorological factors and cyclic oscillations in hospitalization numbers were controlled. Results. A significant increase in hospital admissions was associated with a 10 ?g/m3 increase in the concentration of black smoke, for cardiovascular diseases: 3.14% (< 0.01) in children and youth under 19 years of age, 1.85% (< 0.001) in 19-64 age group, and 0.84% (< 0.05) in all ages, and for respiratory diseases: 1.77% (< 0.05) in 19-64 age group, and 0.91% (< 0.05) in all ages. The effects on hospitalizations for respiratory diseases in children and youth under 19 years of age, and for cardiovascular and respiratory diseases in the elderly were not statistically significant. The increase of sulphur dioxide level was associated with the increased number of hospitalizations, for both cardiovascular and respiratory diseases in all age groups, but the influence was not statistically significant. Conclusion. Outdoor pollutants concentrations in urban area of Nis were below regulated limit values during most of the investigated period days but it is shown that even such a level of pollution has a significant effect on hospital admissions for cardiovascular and respiratory diseases.

ABSTRACT BACKGROUND: The bacterium Helicobacter pylori is strongly associated with the development of gastric adenocarcinoma. Currently, the prevalence in developed countries is 40%, but this value increases considerably in developing countries, which can reach rates bigger than 90%. OBJECTIVE: The objective of this study was to determine the mean and annual prevalence of Helicobacter pylori infection in patients from Itajaí during the period from July 1992 to April 2016, as well as the gender and age groups most affected. METHODS: After consent of the clinical director of the Gastroclinica Itajaí and confidentiality commitment about the research, the database of the Endoscopy Service of the clinic was evaluated. All the patients who underwent their first upper digestive endoscopy with urease test and/or histological analysis were included. The data were submitted to statistical analysis of prevalence by gender, age group and years of study, with subsequent correction through the confidence interval. RESULTS: The mean prevalence of Helicobacter pylori infection thru all years of study was 50.07%. With the calculation of the annual prevalences, it was evident the gradual reduction of infection in the population of Itajaí, that was 81.3% in 1992, declining to 33% in the year of 2016. When classifying the prevalence of infection by gender, it was higher in males (53.59%), and gender distribution by age group showed no statistically significant difference among genders between the ages of 40 and 80 years. In relation to the age group, the highest prevalence was in the group between 40 and 49 years. CONCLUSION: Although this study is retrospective and based on endoscopic database analysis, without access to clinical data of patients such as prior use of proton pump inhibitor and antibiotics to endoscopy, its results are important because they may reflect the current panorama of Helicobacter pylori infection in the city under study, where it has been presenting a gradual reduction of prevalence over the years, with current rates similar to that of developed countries (33%). Future studies are needed to confirm our data.

e12570 Background: Breast cancer (BC) is the second most common malignancy and the leading cause of death by cancer in Peruvian women (age-standarized rate [ASR] of 34 new cases/100,000 women estimated by GLOBOCAN 2008). The purpose of this study was to assess the incidence of BCin acohort ofwomenat Oncosalud, an oncologic pre-paid system that currently has 600,000 affiliates. Methods: We evaluated a dynamic cohort (period 1989 to 2011) of women affiliatedat Oncosalud – AUNA, an oncologic prepaid system.The crude incidence rate per year (number of new cases/women at risk), the specific rate according to age (number of new cases / persons-year) and cumulative risk were calculated. Results: Overall, during the assessment period, the BC incidence rate per year was 175.6 and the ASR incidence was 111.9 per 100,000 affiliates respectively. In our cohort of affiliates there were no BC cases before 1993 (with 907 women at risk for that year). The highest incidence rate was 177.6 registered in 1997 (11,822 women at risk). Incidence rates started decreasing in 2003 (169.2 with a population at risk of 39,593 women). The lowest incidence was 71.5, registered in 2011 (279,680 women at risk).According to age-groups, there were no BC cases under20 years old. Specificincidence ratesper age-group increases from the 30 year old-group (55.8). The peak of BC incidence was between 70 to 74 years old (407.4). In the same way, the cumulative risk increases after 30 years old. Conclusions: In our cohort of affiliates, the incidence of BC is greater than the general population, it could be due to the process of negative selection; however, specific incidence rates per age-group and cumulative risk are increased after 30 years, as seen in the general population.

This study examined the on-line processing of French sentences in a grammaticality judgment experiment. Three age groups of French children (mean age: 6;8, 8;6 and 10;10 years) and a group of adults were asked to detect grammatical violations as quickly as possible. Three factors were studied: the violation type: agreement violations (number and gender) vs. word order violations; the violation position: early vs. late in the sentence; the target type of the violations: intra vs. interphrasal. An example of an early interphrasal verbal agreement violation follows: ‘Chaque semaine la voisine remplissent le frigo après avoir fait les courses au marché’ (Every week the neighbour fill the fridge after shopping at the market). The main developmental results were the following: not surprisingly, children were always slower than adults in the detection of grammatical violations. At each age level, morphological violations were more rapidly detected than word order violations. Each age group was faster at judging sentences with later occurring violations and the position effect was especially strong in the youngest groups. Finally, intraphrasal violations were more rapidly detected than interphrasal ones, this effect being observed only in the oldest groups (i.e. 10;10 years and adults). The results were compared to previous on-line data obtained in modern Greek (Kail & Diakogiorgi, 1998) showing strong similarities, even though Greek is a very rich morphological language. These results are discussed within the framework of the Competition Model, outlining the necessity to incorporate new processing constraints into the model.

ABSTRACT Objective: To analyze mortality from idiopathic pulmonary fibrosis (IPF) in Brazil over the period 1979-2014. Methods: Microdata were extracted from the Brazilian National Ministry of Health Mortality Database. Only deaths for which the underlying cause was coded as International Classification of Diseases version 9 (ICD-9) 515 or 516.3 (until 1995) or as ICD version 10 (ICD-10) J84.1 (from 1996 onward) were included in our analysis. Standardized mortality rates were calculated for the 2010 Brazilian population. The annual trend in mortality rates was analyzed by joinpoint regression. We calculated risk ratios (RRs) by age group, time period of death, and gender, using a person-years denominator. Results: A total of 32,092 deaths were recorded in the study period. Standardized mortality rates trended upward, rising from 0.24/100,000 population in 1979 to 1.10/100,000 population in 2014. The annual upward trend in mortality rates had two inflection points, in 1992 and 2008, separating three distinct time segments with an annual growth of 2.2%, 6.8%, and 2.4%, respectively. The comparison of RRs for the age groups, using the 50- to 54-year age group as a reference, and for the study period, using 1979-1984 as a reference, were 16.14 (14.44-16.36) and 6.71 (6.34-7.12), respectively. Men compared with women had higher standardized mortality rates (per 100,000 person-years) in all age groups. Conclusion: Brazilian IPF mortality rates are lower than those of other countries, suggesting underdiagnosis or underreporting. The temporal trend is similar to those reported in the literature and is not explained solely by population aging.

Background: Autopsy examination is mandatory in all unnatural deaths as per law of Nepal and thus all deaths due to drowning are undergone medico legal autopsy. This study aims to analyze the demographic and autopsy characteristics of drowning deaths in cases brought for medico legal autopsy at a major autopsy center of Gandaki province of Nepal. Methods: This study was conducted based on review of database in a period of two years among 53 corpses of drowning related deaths. The demographic data and relevant information from the inquest and autopsy report of such cases were collected and presented. Result: The commonest age group involved in drowning deaths was <20 years, attributing to 22 (41.5%) cases, and with males (41, 77.4%) more common than females. Suicidal drowning (34, 64.2%) was the commonest manner. Maximum (19, 35.8%) deaths occurred in the rainy season and on lakes (34, 64.1%). Conclusion: Drowning deaths were more common among males of young age groups. Most of the drownings occurred during the rainy season, lakes were the common sites of drowning, and the commonest manner was suicidal.

BackgroundVision-dependent mechanisms play a role in myopia progression in childhood. Thus, we investigated the distribution of ocular and corneal higher-order aberrations (HOAs) in highly myopic Chinese children and adolescents and the relationship between HOA components and 1-year axial eye growth.MethodsBaseline cycloplegic ocular and corneal HOAs, axial length (AL), spherical equivalent (SE), astigmatism and interpupillary distance (IPD) were determined for the right eyes of 458 highly myopic (SE ≤−5.0D) subjects. HOAs were compared among baseline age groups (≤12 years, 13–15 years and 16–18 years). Ninety-nine subjects completed the 1-year follow-up. Linear mixed model analyses were applied to determine the association between HOA components, other known confounding variables (age, gender, SE, astigmatism and IPD) and axial growth. A comparison with data from an early study of moderate myopia were conducted.ResultsAlmost all ocular HOAs and few corneal HOAs exhibited significant differences between different age groups (all p<0.05). After 1 year, only ocular HOA components was significantly negative associated with a longer AL, including secondary horizontal comatic aberration (p=0.019), primary spherical aberration (p<0.001) and spherical HOA (p=0.026). Comparing with the moderate myopia data, the association of comatic aberration with AL growth was only found in high myopia.ConclusionIn highly myopic children and adolescents, lower levels of annual ocular secondary horizontal comatic aberration changes, besides spherical aberrations, were associated with axial elongation. This suggests that ocular HOA plays a potential role in refractive development in high myopia.

Objective: No assessment was conducted describing the age and gender specific epidemiology of lung cancer (LC) prior to 2018 in Hungary, thus the objective of this study was to appraise the detailed epidemiology of lung cancer (ICD-10 C34) in Hungary based on a retrospective analysis of the National Health Insurance Fund database.Methods: This longitudinal study included patients aged ≥20 years with LC diagnosis (ICD-10 C34) between January 1, 2011 and December 31, 2016. Patients with different cancer-related codes 6 months before or 12 months after LC diagnosis or having any cancer treatment other than lung cancer protocols were excluded.Results: Lung cancer incidence and mortality increased with age, peaking in the 70–79 age group (375.0/100,000 person-years) among males, while at 60–69 age group for females (148.1/100,000 person-years). The male-to-female incidence rate ratio reached 2.46–3.01 (p &lt; 0.0001) among the 70–79 age group. We found 2–11% decrease in male incidence rate at most age groups, while a significant 1–3% increase was observed in older females (&gt;60) annually during the study period.Conclusion: This nationwide epidemiology study demonstrated that LC incidence and mortality in Hungary decreased in younger male and female population, however we found significant increase of incidence in older female population, similar to international trends. Incidence rates peaked in younger age-groups compared to Western countries, most likely due to higher smoking prevalence in these cohorts, while lower age LC incidence could be attributed to higher competing cardiovascular risk resulting in earlier mortality in smoking population.
