Awareness of obstetric warning signs in Ecuador: a cross-sectional study.

OBJECTIVE: In Ecuador, the reported maternal death rate was 45.71 per 100,000 live births in 2013. This may be partly due to a lack of maternal knowledge of obstetric warning signs during pregnancy, delivery and the post-partum period. This study sought to evaluate awareness of obstetric warning signs among pregnant women in relation to individual demographic and area-level socio-economic indicators. STUDY DESIGN: We conducted a cross-sectional analysis of data collected by Ecuador's Ministry of Health at the conclusion of a national maternal health campaign (2014-2015). A nationally representative sample of 3435 pregnant women from the nine administrative zones completed surveys regarding basic demographics and their awareness of obstetric warning signs. METHODS: We defined eight obstetrical warning signs according to the literature and Ecuadorian practice that could occur during pregnancy, delivery and the post-partum period (severe headache, strong abdominal ache, bleeding or presence of malodorous secretion, rupture of the amniotic sac, high fever, abnormal presentation of the baby, decrease in baby's movements and delayed labour). A woman was considered 'aware' if she recognised at least four of the eight warning signs and stated she would seek immediate healthcare at their presentation. For each administrative zone, four socio-economic indicators (poverty, illiteracy, unemployment and subemployment) were obtained from the National Institute of Statistics and Census. Correlates of awareness of the obstetric warning signs were evaluated using hierarchical logistic models clustered by the administrative zone. RESULTS: Nationally, 86.9% of women were 'aware' of obstetric warning signs. After adjustment for age, socio-economic indicators and clustering, indigenous participants were 59% less likely to be aware of obstetric warning signs than mestizos (odds ratio [OR] = 0.41, 95% confidence interval [CI] = 0.28-0.59). For every 1% increase in area poverty, participants had a 5% decreased likelihood of being aware of obstetric warning signs (OR = 0.95, 95% CI = 0.93-0.96), adjusting for age, ethnicity and other socio-economic indicators. The most effective source of campaign information about obstetric warning signs was personal communication with a healthcare professional, as opposed to mass media advertisements (OR = 1.90, 95% CI = 1.34-2.71). CONCLUSIONS: A majority of Ecuadorian pregnant and post-partum women are aware of obstetric warning signs. Indigenous ethnicity and area-level poverty are associated with a lack of awareness. Personal communication with a healthcare professional was the most effective source of information. These findings have implications for improvement of maternal awareness of warning signs.

Moving towards the immunodiagnosis of staphylococcal intramammary infections.

Bovine mastitis is the primary disease of dairy cattle that has a great impact on the dairy industry. It is estimated that worldwide economic losses due to mastitis range between US$82 and US$131 per cow/year. A fast and efficient diagnosis of the disease remains a major bottleneck that directly influences the speed with which treatment decisions and management are undertaken. Microbiological culture remains the gold standard in the identification of bacteria that cause mastitis, but the method has inherent limitations, such as a delay in obtaining results and cost, and requires special care during the collection and processing of the sample. For this reason, multiple groups have devoted efforts to develop alternative methods that, preferably, can be easily accomplished in the field. The specificity of the antigen-antibody reaction has enabled the emergence of major diagnostic methods used in clinical practice, such as immunoassays, which have significant advantages in terms of speed, sensitivity, specificity, and portability. Commercially, immunodiagnostics have been used in the detection of various diseases in cattle. However, in several cases, only a presumptive diagnosis can be made, which requires confirmation using culture-based methods. This review discusses the immunological-based assays developed since the 1990s for the detection of Staphylococcus aureus, which is considered the primary pathogen of contagious bovine mastitis. Although no ideal antigens ensure the accurate performance of tests and the costs need to be reduced to allow for good market competitiveness, immunoassays, particularly lateral flow immunoassay and immunoagglutination, have emerged as promising tests to be used in the field.

Root resorption in deciduous teeth after applying orthodontic forces.

The relation between orthodontic forces applied to deciduous teeth and the occurrence of root resorption, as a possible outcome of these forces, has not been studied to date. The aim of this work was to study root resorption in deciduous teeth of patients receiving orthodontic treatment. Twenty-four deciduous molars extracted for therapeutic purposes were studied: nineteen molars treated with light orthodontic forces and five untreated molars that served as control. Histological and histomorphome tric studies were performed to determine the magnitude of root resorption. Location of root resorption in treated deciduous teeth was different from that of physiological root resorption. Extent and volume of root resorption were more extensive and deeper in treated than in untreated teeth. These results suggest that radiographic follow-up of deciduous teeth subjected to orthodontic forces would be useful to prevent root fractures.

Root resorption in elderly patients.

Root resorption in permanent teeth is a frequently observed pathology that may originate in various causes. Life expectancy is progressively rising, odontological preventive care is becoming more widespread and professionals are educating their patients in the importance of preventive practices. Because senior citizens are thus losing fewer teeth prematurely they will be conversely more at risk for dental problems later in life. The knowledge of the alterations that may appear in the roots of geriatric patients is particularly relevant to devising therapy and establishing prognosis. The aim of the present study was to evaluate the nature and magnitude of the histologic and histomorphometric features of root resorption and the eventual possibility of repair in elderly people. Seventy-seven uniradicular teeth of patients aged between 65 and 90 years and 18 premolars of patients aged between 14 and 20 years, were removed, fixed in 90% formalin, decalcified in EDTA and embedded in paraffin. Vestibulo-lingual sections were stained with hematoxylin-eosin and employed to perform histological and histomorphometric studies. The results showed that 30% of the teeth of younger patients and 94% of the teeth of elderly patients exhibited areas of root resorption. From the 416 resorptive areas found in elderly patients, 173 exhibited signs of repair being the volume/surface ratio of these areas 0.69 +/- 0.06. These data show that root resorption is a frequent finding in the older population under study. Resorptions are characterized by scarce depth, large areas and a high incidence of repair despite the old age of the patients.
