Abstract Objectives: To estimate the secular trend in age at menarche, comparing indigenous and nonindigenous women, its relationship with socio‐demographic, family nutritional factors. Methods: A study (historical cohorts) of 688 divided into four birth cohorts (1960–69, 1970–79, 1980–89, 1990–96) an area central southern Chile was carried out. Data measurements were collected by health professionals using a previously validated questionnaire. Age menarche self‐reported (recall). Adjusted...
Infectious vaginitis is a microbiological syndrome of great importance in public health that affects millions women worldwide. However, no studies have explored the phenomenon production neutrophil extracellular traps (NETs) are released into female reproductive tract these pathologies. This study aimed to determine presence NETosis vaginal discharges with bacterial vaginosis, candidiasis, and trichomoniasis by characterizing NETs. Extracellular DNA elastase citrullinated histones was...
Age-related hearing loss is an important risk factor for cognitive decline. However, audiogram thresholds are not good estimators of dementia in subjects with normal or mild loss. Here we propose to use distortion product otoacoustic emissions (DPOAEs) as objective and sensitive tool estimate the decline older adults
Trichomoniasis, a globally distributed sexually transmitted infection, is caused by the urogenital parasite Trichomonas vaginalis Donné, 1836 affecting both women and men. The treatment of choice metronidazole (MTZ). In present study, 15 samples vaginal discharge urine were analysed sequencing nitroreductase genes (ntr4 ntr6). An in silico model was structured to illustrate location point mutations (PM) protein. ntr4 gene presented four PMs: G76C (10/10), C213G (9/10), C318A (5/10) G424A...
Abstract Data on reproductive traits from 1,229 mature 2-year-old female coho salmon Oncorhynchus kisutch were collected during 2 years at four farms in southern Chile. Spawning periods similar 1993 and 1994 (39 41 d, respectively). The spawning period of May–June, corresponded to the full northern hemisphere. mean weight females (about 4 kg) was almost double reported hemisphere for maturing females. pigmented eyed stage reached approximately 270 accumulated temperature units (ATU days × °C...
Biomass burning is common in much of the world, and some areas, residential wood-burning has increased. However, air pollution resulting from biomass an important public health problem. A sampling campaign was carried out between May 2017 July 2018 over 64 sites four sessions, to develop a spatio-temporal land use regression (LUR) model for fine particulate matter (PM) tracers levoglucosan soluble potassium (Ksol) city heavily impacted by wood-burning. The mean (sd) 46.5 (37.4) μg m-3 PM2.5,...
Thelarche and nutritional status: An epidemiological study of two ethnic groups Background: Improvements in environmental conditions may result an earlier onset thelarche.However, its is not homogeneous among different population groups.Aim: To assess the relationship between status, ethnicity age thelarche.Material methods: Cross-sectional girls second through sixth grade, attending 165 schools located Chile's Araucania region.Of these, 231 who presented thelarche (breast button) were...
Abstract: Automatic geocoding methods have become popular in recent years, facilitating the study of association between health outcomes and place living. However, rather few studies evaluated quality, with most them being performed US Europe. This article aims to compare quality three automatic online tools against a reference method. A subsample 300 handwritten addresses from hospital records was geocoded using Bing, Google Earth, Maps. Match rates were higher (> 80%) for Maps Earth...

Métodos estudo qualitativo em mulheres zonas urbanas e rurais, entre 20 44 anos idade, nas comunas Temuco Padre Las Casas, Chile. A técnica empregada para coleta dados foi entrevista profundidade. O método indutivo análise, baseado na Teoria Fundamentada Dados ( Grounded Theory ), possibilitou um processo comparativo constante até [...]
To determine the concordance between clinical diagnosis of women with abnormal vaginal discharge (AVD) and laboratory results using molecular detection observation microbiota. Cross-sectional study conducted in 2018 Temuco, Chile. A total 25 midwives from 12 health centers participated. 125 > 18 years old, volunteers, were recruited. The sample posterior fornix was obtained by speculoscopy. Characteristics external internal genitalia observed. Gram staining used to observe microbiota,...
Age at menarche and indigenous ancestry.A population study in Chile
Chilean salmon culture is based on a high degree of artificial selection, which has had the tendency to increase inbreeding (F). Three types nonrandom mating were evaluated control in two best linear unbiased prediction selected coho (Oncorhynchus kisutch) populations (even and odd). These included compensatory basis breeding values (C), modified (C1) family mean values, that minimized co-ancestry group (MC scheme). In odd population, MC scheme (F = 2.0%) reduced next generation by 50% 46%...
OPS 10: Wildfires, Room 210, Floor 2, August 26, 2019, 10:30 AM - 12:00 PM Land use regression models have been widely employed in environmental epidemiology to predict spatiotemporal variation of air pollution. The spatial variability fine particulate (PM2.5) due wood-burning has not studied Chile. In this study, we used data from a sampling campaign develop Land-Use Regression (LUR) model city heavily impacted by wood-burning: Temuco, Models were built based on field similar following the...
