Epidemiology of risk factors in pregnancy focused on caesarean section
Full text linkThe frequency of termination of pregnancy by Caesarean sectioncontinued to grow since the 70 flight the last century, in the Euro-Atlantic area is 10-30%. In the Czech Republic to follow a similar trend. In 2007, was terminated in this manner approximately 20% of births, it represents 8% growth rate over the past 10 years (Velebil et al., 2008). In the eyes of the public has a reputation for caesarean seeminglysimple and safe performance. There are women who prefer it and ask for their obstetrician termination of pregnancy in this way. The aim of this work is a comprehensive report caesarean section, with emphasis on its complications that may endanger the mother, but also the newborn
Complication during pregnancy - Epidemiology and risk factors
Full text linkRisk pregnancy can be complicated by many factors which can switch physiological pregnancy to pathological pregnancy. Screening during pregnancy helps find risks and eliminate or treat pregnancy diseases. If a risk is discovered in general screening, specific screening follows. Effective prenatal screening results in a good perinatal epidemiology outcome. A pregnant women addicted to drugs risks pregnancy pathology, intrauterine growth retardation of the fetus and a neonate with problems in postnatal adaptation
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Perinatal morbidity and its prevention
Full text linkWithin the perinatal period, the mother and the fetus exposed complications that may jeopardize or adversely affect their life. The thesis is focused on maternal morbidity, from which I most impressed operative deliveries, particularly repeat cesarean (SC). SC has now become convenient and safe public awareness and way to bring a child into the world. But is it really so? Few people seem to think the risks for the next birth in women with a history of SC. The number of women mainly from the 80s has risen considerably, so I think that is a current topic and discussed
Complications during pregnancy-Epidemiology and risk factors
Full text linkRisk pregnancy is the term denoted to a pregnancy with a higher chance of developing a pathology than that of the normal population. Although risk pregnancies form 30% of all pregnancies only 20% to 30% of them actually develop a pathology. The higher than average risk can be present before conception or it is acquired during pregnancy. In order to identify risk factors general (medical history and physical examination) through specific screening is used. In case of a positive screening result specific prevention methods are applied. One of the late risk factors identified in pregnancies are sexually transmitted diseases, especially if their course is asymptomatic. Prevalence of urogenital chlamydia infections has been increasing, and various screening programs have been evaluated for their cost benefit ratio. Developed countries have introduced successful screening and preventive programs for hepatitis B infection. Also vertical transmission of HIV to the newborn is met by efficient preventive methods in developed countries. These methods, however, are not available in most of developing countries. Other than these there is also a serological screening for syphilis infections. There is no routine serological screening for the rest of sexually transmitted disease
Complications during pregnancy - epidemiology and risk factors
No full textPregnancy is a normal, healthy state which most women aspire to at some point in their lives. Yet this normal process carries with it serious risks of death and disability to mother, child or both. The worst outcome of these complications is maternal or fetal death. In this work, the focus will be on maternal death, maternal mortality ratio worldwide, causes and to review what is done in order to prevent and decrease the high number of avoidable deaths. The fact is that worldwide, eight million women suffer pregnancy-related complications and over half a million young women die every year as a result of complications arising from pregnancy and childbirth. 99% occur in developing countries. Most of these deaths could be avoided if preventive measures were taken and adequate care available, this including adequate nutrition, improved hygiene practices, family planning available for all, antenatal care, skilled health workers assisting at births, emergency obstetric and newborn care, and postnatal visits for both mothers and newborns. In developing countries, one woman in 16 may die of pregnancy-related complications compared to one in 2800 in developed countries
Komplikace v těhotenství - epidemiologie a rizikové faktory
No full textComplications of pregnancy are the problems that are associated with pregnancy. The routine problems are common complications, and pose no significant danger to either the mother or the fetus. Serious problems can cause both maternal death and fetal death if untreated. Estimates from the World health organization in 2001 suggests that complications during pregnancy and childbirth are responsible for the deaths of 515 000 women each year. Sub-Saharan Africa is the area of greatest mortality. The common causes of maternal mortality worldwide are hemorrhage, infections, eclampsia, unsafe abortions and many more. Ectopic pregnancy occurs in about 1-2% of pregnancies. The incidence has increased the past decades, likely due to increased incidence of salpingitis, improved detection, increased maternal age, tubal sterilization techniques, assisted reproductive techniques, and the use of tubal surgery. The miscarriage of an early pregnancy is the commonest complication , with one in two conceptions lost before the end of the first trimester. Risk factors for miscarriage include increased maternal age, uterine abnormalities, infections, and chemical agents like tobacco.Ústav pro péči o matku a dítě v Praze PodolíDepartment of Mother and Child Care in Prague PodoliThird Faculty of Medicine3. lékařská fakult
