Abstract:
Objective: Evaluate perinatal and neonatal outcomes comparing a water birth to regular childbirth in low-risk women. File and methods: Retrospective analysis of a set of childbirths that took place over a given period of time in the hospital and health center of Havířov. We compared a set of low-risk women that had given a water birth to a selected control group of low-risk women that had given regular childbirth. We evaluated statistical comparability, as well as perinatal and neonatal outcomes in both sets. Results: From 1. 1. 2020 to 28. 2. 2021, 1,083 women gave birth in the delivery department of Havířov hospital; from this set 122 were water births (11.3%). In our study, we only included 101 water deliveries (we designed our study to monitor low-risk births in order to be able to statistically correlate our fi ndings; 21 water deliveries were excluded from our study due to perinatal risk factors – gestational diabetes and induced deliveries). We selected 60 low-risk women for our control group. Both sets of women were compared and we ruled out any statistically signifi cant diff erences in age, education, body mass index, number of births given, gestation week at time of labor, number of smokers, premature rupture of membranes, women with previous history of one cesarean section, becoming pregnant by in vitro fertilization, presence of streptokoka skupiny B, and fetal weight. Water birth does not aff ect the Apgar score, neonatal adaptation to extra-uterine life, umbilical blood pH decrease, complications of infection, need of intensive care, and neonatal mortality. In the water birth set, we found increased occurrence of non-infectious conjunctivitis, treatable by regular eye drops without antibio tics. We have not observed the eff ect of water birth on duration of the fi rst and second stage of labor, total amount of uterotonics used, blood loss determined by the obstetrician, and uterine hypotonia. In the water birth group, we observed a prolonged third stage of delivery, lesser need for pharmacological stimulation (augmentation) of labor, notably lower use of analgesics, lower occurrence of birth injuries, shorter in-patient time, and more frequent bonding. Conclusions: We discovered that water birth does not increase the risk for mother and neonate in low-risk women. Despite initial concerns, our outcomes and mother satisfaction have clearly shown that water births are not only a temporary whim, but probably a new integral part of our obstetric care. Key words: water birth – analgesia with water – childbirth – perinatal and neonatal outcomes

Abstract:
ABSTRACTIn this birth story, Katherine shares that she wanted an unmedicated birth. She planned a hospital birth with a midwife. During her pregnancy, she hired a doula and she and her husband, Corey, attended both natural childbirth classes and a natural comfort measures class. Katherine had an intense labor but was able to relax between contractions, and with the support of her husband and doula, she managed to cope with increasingly difficult contractions. Her commitment and hard work during labor, and the emotional and physical support she received, helped her achieve the unmedicated birth she wanted. Katherine and her husband welcomed their daughter, Clara Mae, into the world after 10.5 hours of labor.

Abstract:
Atrazine, a common water contaminant in the U.S., has been associated with adverse birth outcomes in previous studies. This study aimed to determine if atrazine concentrations in drinking water are associated with adverse birth outcomes including small for gestational age (SGA), term low birth weight (term LBW), very low birth weight (VLBW), preterm birth (PTB), and very preterm birth (VPTB). This study included 14,445 live singleton births from Ohio communities served by 22 water systems enrolled in the U.S. Environmental Protection Agency’s Atrazine Monitoring Program between 2006 and 2008. Mean gestational and trimester-specific atrazine concentrations were calculated. Significantly increased odds of term LBW birth was associated with atrazine exposure over the entire gestational period (OR 1.27, 95% CI 1.10, 1.45), as well as the first (OR 1.20, 95% CI 1.08, 1.34) and second trimesters (OR 1.13, 95% CI 1.07, 1.20) of pregnancy. We observed no evidence of an association between atrazine exposure via drinking water and SGA, VLBW, PTB, or VPTB. Our results suggest that atrazine exposure is associated with reduced birth weight among term infants and that exposure to atrazine in drinking water in early and mid-pregnancy may be most critical for its toxic effects on the fetus.

Abstract:
Our research investigated the correlations of five key contaminants in drinking water in the State of Illinois with the incidence rates of three different categories of negative reproductive outcomes: birth defects, adverse pregnancy outcomes and preterm births. The five water contaminants included three agrichemical-based contaminants (atrazine, nitrate and nitrite) and two disinfectant byproducts (total trihalomethanes and haloacetic acids). We obtained nearly 38,000 measurements of the individual concentrations of these five contaminants from the Illinois Environmental Protection Agency (IEPA). These data, spanning over a five-year period (1998-2002), were collected from nearly 1,800 community water supplies (CWS) located in all 102 Illinois counties. The county-specific incidence rate data for the same time period for preterm births, seven groups of birth defects and seven groups of adverse pregnancy outcomes were collected from the Illinois Department of Public Health (IDPH). The traditional approach of establishing correlation of one explanatory variable at a time indicated that nitrate concentration in drinking water was statistically correlated to the incidence rate of only one category of negative reproductive outcome, i.e., birth defects. However, multiple regression analysis, which took into consideration all water contaminant data simultaneously, established statistical significance of the correlation between nitrate and all three categories of negative reproductive outcomes. Total trihalomethanes (TTHM) and haloacetic acids (HAA5) were also found to be the statistically significant explanatory variables for all three types of negative reproductive outcomes. Nitrite was found to be associated with adverse pregnancy outcomes and preterm births only; its correlation with birth defect rates could not be established at 80% confidence level. Atrazine was found to be among the significant explanatory variables for all three negative reproductive outcomes. However, its correlations with birth defect model developed using censored data and preterm birth model developed based on observed data were not statistically significant. Nearly 21.5%, 35.8% and 16.6% of the variabilities in incidence rates of different types of birth defects, adverse pregnancy outcomes and preterm births, respectively, were correlated to average concentrations of above mentioned five contaminants in community drinking water supplies. The monthly average concentrations of two of three agrichemical-based contaminants, i.e., atrazine and nitrate were significantly higher in SW(surface water)-based than GW(ground water)-based community water supplies. On the other hand, concentrations of both disinfectant byproducts and the other agrichemical-based contaminant, i.e., nitrite were significantly higher in GW-based water supplies. Further correlation analysis based on the actual observed concentration (excluding all 0 detections) was conducted utilizing SW-based atrazine and nitrate data and GW-based nitrite, TTHM and HAA5 data. All categories of negative reproductive outcomes were found significantly correlated with at least one type of water contaminants. The overall negative reproductive outcomes were correlated with nitrate, nitrite and atrazine. Birth defects specifically correlated with nitrate and TTHM, whereas adverse pregnancy outcomes were correlated with nitrate, nitrite and HAA5; preterm birth was correlated with the concentrations of nitrite, atrazine and TTHM. Further investigation indicated significant correlations among the explanatory variables (drinking water contaminants data), which is referred as multicollinearity. In such case, multiple linear regression based analysis may not provide reliable results. Partial least squares (PLS) approach of regression analysis was introduced into our study to overcome the multicollinearity problem. As much as 65.5% of the variability in the county-wide average concentrations of five contaminants in public drinking water supplies was explained by the 4 component PLS regression model, whereas only 7.7% of the incidence rates of different types of birth defects, adverse pregnancy outcomes and preterm births in various Illinois counties, were explained by PLS regression. Although, individual negative reproductive outcome model could be generated, the low R2 values indicated the poor reliability of these models. We attempted to corroborate our statistical analysis findings with the physiological effects of various water contaminants reported in the literature. It is well known that excessive exposure to any of the five key water contaminants may cause malfunction of organism or the immune system, reproduction, nervous and endocrine system and others, which may further result in potential risk of developing adverse effects. Nitrate and nitrite in drinking water associate to a certain extent with congenital malformations, such as central nervous system abnormalities, in human offsprings. Excessive exposure to atrazine is known to increase the risk of potential cardiovascular or reproductive system problems. A certain type of TTHM, i.e., BDCM are known to be associated with an increased risk of spontaneous miscarriage in pregnant women. It also may result in an increased risk of reproductive problem, such as fetal growth restriction.

Abstract:
The use of deep-water immersion during labour and birth is commonplace in many countries including Australia, yet there has been little contemporary Australian data from which to form policies regarding its use during childbirth, or which have included women’s experiences using water immersion. The literature reviewed for this study was positive with regard to the effect of water immersion during childbirth and was associated with decreased rates of perineal trauma, low episiotomy rates, low rates of analgesic use, lower operative deliveries coupled with increased maternal satisfaction of the experience of childbirth when compared with births where water immersion was not involved. The purpose of this research was to investigate the influence of deep-water immersion upon maternal and neonatal outcomes and women's experiences of giving birth in Australia. This study used a mixed method in an attempt to fulfil this purpose: the first phase was a Quasi-experimental design and the second phase was based upon a Hermeneutic Phenomenological approach. Data were collected via a Random Chart Audit, from a random sample of fifty nulliparous women who used deepwater immersion during labour and childbirth and six women were selected to participate in a semi-structured interview. Data from each phase of this study revealed positive birth outcomes and these findings were supported by the literature. The women's stories were positive and comprised elements of four lifeworld themes. • Water’s Embrace • Warped Time • Naked but Clothed • The Shape of Water. Each of these themes encapsulated different aspects of the women's experiences, which when considered together, increased the understanding of the phenomenon of deep-water immersion upon the experience of giving birth.

Abstract:
When the special moments of life and death are imminent, where do you want to be? My thesis seeks to create an eco-sensitive, sustainable building that celebrates the time and place of two of life s most amazing events: birth and death. Rather than a conventional singular center, my thesis proposes a combined program for a new architectural project type: a Birthing and Hospice Center. Although the concept may be surprising, once people fully understand that we live in a closed system and embrace the cyclical nature of life, it is an appropriate program that represents another aspect of sustainability. The project site is located in an urban area of Old Town Alexandria, Virginia along the Potomac River. The Birthing and Hospice Center integrates both the human life cycle and the material life cycle of the building s materials, water, and site for a holistic experience and celebration. It explores how to heighten our environmental experience of place, light, air, water, and time. My thesis seeks to create a beautiful place where people can celebrate their own special event, while at the same time, understand and celebrate the larger realm of the natural life cycle.

Abstract:
Disinfection of drinking water is vital to protect the public against disease. However disinfectants such as chlorine react with organic matter in drinking water to produce a wide range of chemical disinfection by-products (DBPs) of potential health concern including haloacetic acids (HAAs). This thesis is an epidemiologic analysis investigating the relationship between prenatal exposure to HAAs in drinking water and adverse birth outcomes in 'Born in Bradford', a large multi-ethnic prospective birth cohort study based in Bradford, England. It focuses on the understudied and as yet unregulated HAAs which are the second most prevalent class of chlorination DBPs in UK drinking waters. To assess exposure, area-level concentrations to three select HAAs (measured in drinking water samples newly collected for this study, modelled in time and space, and weighted to each cohort woman's specific trimester of pregnancy by postcode of residence) were combined with individual water consumption information collected via questionnaire at recruitment to the cohort. Despite the benefits of state-of-the-art exposure metrics and a large sample size, this study does not find any significant patterns of association between prenatal exposure to HAAs and either birth weight, being born term low birth weight or small-for-gestational age. Water consumption over the course of late pregnancy was further studied in a subset of cohort women. A small but significant increase in water consumption was reported, bearing in mind that both behaviour change over the third trimester of pregnancy and measurement error likely contributed to this effect. This research addresses some of the limitations of previous DBP studies in terms of exposure assessment and birth outcome definitions, and uniquely evaluates the variability of individual water consumption over time. It also identifies areas for future research and examines the importance of HAAs and birth weight-based outcomes in the larger research context.

Abstract:
Fragestellung/Hintergrund: In den letzten Jahren hat die Wassergeburt eine weite Verbreitung gefunden. Die Geburt eines Kindes ist als 'life-event' (Kentenich) im Leben werdender Eltern zunehmend ins Bewusstsein gerückt. So soll nach den Forderungen der Eltern in möglichst häuslicher Umgebung mit Freiraum für eigene Gestaltung das Spektrum medizinisch-technischer Möglichkeiten im Bedarfsfall verfügbar sein. Um Zufriedenheit mit dem Geburtserlebnis zu erreichen, müssen die an eine Geburtsklinik gestellten Erwartungen erfüllt werden. So ist es unser Anliegen, eine Geburtshilfe anzubieten, welche auch als psychosomatisch verstandene Geburtshilfe die Zufriedenheit der Eltern zum Ziel hat. Methode: Die vorliegende Untersuchung ist eine Fall-Kontrollstudie, in der die Geburtsmodi Wassergeburt und Bettgeburt auf drei Aspekte hin untersucht wurden: Daten des Fetal Outcome, mütterliche geburtshilfliche Parameter sowie Daten zum Geburtserlebnis, der Geburtsvorbereitung, der Assoziation zum Thema Wassergeburt und soziodemographische Variablen. Anhand des letzten Aspektes wurde untersucht, ob ein Zusammenhang besteht zwischen dem Geburtsmodus und der Zufriedenheit mit dem Geburtserlebnis. Weiterhin wurde die mikrobiologische Kontamination des Badewassers untersucht. Ergebnisse: Die Kollektive unterschieden sich nicht hinsichtlich Parität, Schwangerschaftswoche und mütterlichem Alter. Bezüglich der mütterlichen geburtshilflichen Parameter und des Fetal Outcome ergaben sich keine signifikanten Unterschiede. Der Entschluss zur Wassergeburt wird von den meisten Frauen (59%) spontan im Kreißsaal getroffen. Das Geburtserlebnis wird von den Frauen der Fallgruppe signifikant besser beurteilt. Es traten keine Neugeboreneninfektionen auf, die durch Keime des Badewassers verursacht wurden. Schlussfolgerung: Die Wassergeburt ist unter Berücksichtigung von Ausschlusskriterien ein sicherer Geburtsmodus für Mutter und Neugeborenes. Die Möglichkeit für die Gebärende, sich spontan für diesen Geburtsmodus zu entscheiden, geht mit einer positiven Bewertung des Geburtserlebnisses einher. Somit ist die Wassergeburt ein sinnvolles Angebot an die Gebärende vor dem Hintergrund der an die Geburtshilfe gestellten Erwartungen.
Objectives: In recent years water birth has obtained much acceptance. Childbirth has more and more taken on the quality of a life event (Kentenich) in the consciousness of expectant parents. While parents want it to take place in a personal and homely atmosphere they whish at the same time to have the security of medical facilities. Parents will be satisfied with the experience of childbirth if their expectations towards obstetrics are fulfilled. Methodology: This study is based on a case-control trial in which water birth and conventional birth in bed have been compared in respect of the following data: fetal outcome, maternal obstetrical parameters, birth event, pre-birth preparation, association regarding the subject of water birth and sociodemographical variables. It has been examined whether there is a correlation between the mode of birth and the satisfaction with the birth event. Furthermore microbiological contamination of bath water after water birth was examined. Results: The two collectives are equal concerning parity, gestational age and maternal age. They have shown no significant differences concerning maternal obstetrical parameters and fetal outcome. The majority of women (59%) make decision for water birth spontaneously in the delivery room. Women in case group have shown a significantly greater satisfaction with birth event. There were no infections in neonates by germs from bath water. Conclusion: With the exclusion of risk-groups water birth is a safe mode of delivery. The possibility for the birth attendants to opt for a mode of birth spontaneously correlates with a positive assessment of birth event. In our opinion water birth is a commendable alternative fulfilling expectations of parents towards modern obstetrics.

Abstract:
Abstract Conventional ICDs were invented for long horizontal wells to promote a more uniform inflow profile. Later, AICDs were developed, which utilize viscosity contrast between fluids to impose a larger hydraulic resistance in sections with inflow of undesired fluids, like gas and water. However, these AICD technologies cannot be used to choke back inflow of water in reservoirs where oil and water have similar viscosities, and they also tend to impose large pressure drops even for single-phase oil at high flow rates. The objective of the work presented here has therefore been to develop an inflow control technology that removes these limitations. The resulting Density Activated Recovery (DAR™) technology utilizes difference in fluid density rather than viscosity contrast to control fluids downhole. It is a fully autonomous, binary system that is either fully open or closed, where "closed" means that it only allows a small pilot flow. More specifically, it can be considered a "dual ICD" with flow through a large port when open, and a small port when "closed". The flow capacity and choking efficiency are therefore fully defined by the diameters of these two ports. Furthermore, it can close and reopen at any pre-determined water and gas fractions, that are completely insensitive to flow rate, viscosity and Reynolds number. This makes it universally applicable to control any wellbore fluid along the entire reservoir section. After successful prototype testing in 2018, the DAR technology has now undergone a comprehensive full-scale system-qualification program including a final flow performance test where the system was tested at 240 bar and 90ºC with saturated 0.8 cP oil. The tests demonstrated up to seven times higher flow capacity with the density-based DAR technology compared with viscosity-dependent AICD technologies. The system successfully and repeatedly closed and reopened for both gas and water. As oil and water had similar viscosities, the tests also proved how this technology can be used to stop undesired inflow of water in light-oil reservoirs. Being insensitive to flow rate, the DAR system is also insensitive to local variations in pressure and productivity along the reservoir section, which reduces the negative consequences of geological uncertainty and allows the same design to be used at every location in the well. It can also be configured to ensure complete mud removal during well cleanup and can even stop inflow of water in gas wells, where the undesired fluid has higher viscosity than the desired fluid. More importantly, this technology can deliver automated reservoir management to a level where it influences how wells are drilled and fields are developed. Accelerated oil production and the reduced need for reinjection of gas/water will also reduce the associated greenhouse gas (GHG) emissions considerably.

Abstract:
The paper presents the research results on the content and spatial dynamics of biogenic elements (ammonium ions, nitrite ions, nitrate ions, mineral phosphorous) in the water of the Bâc river. The aim of the research was to determine the water quality of the Bâc river, in order to highlight the extent of the impact of anthropic factors on the river and to reveal the impact of the Bâc river on the state of the Dniester river. The water of the Bâc river, downstream of Calarasi, Straseni and Chisinau, is highly polluted with ammonium, nitrites, mineral phosphorus, which corresponded to the IV-V class of water quality - polluted and heavily polluted. The results of the research confirm the high degree of pollution with biogenic elements causing the changes of water quality in the Dniester river.

Abstract:
The article is dedicated to the legal aspects of bilateral water relations of Moldova and Ukraine on their joint Dniester River demonstrating that only the following international legislation on transboundary waters could help both riparians to save the river for future generations. Current situation with domination of hydrower as dominating used is unacceptable from the sustainable development view. The newly created Dniester River Commission could be a tool to establish a dialogue and a platform for wise decision making. The success could be only reached in case of following the best international standards due to climate change consequences for the region, which provoke droughts etc.
