Objective: To evaluate the effect of maternal oral hydration on amniotic fluid index (AFI) in pregnancies with fetal gastroschisis. Methods: AFI was evaluated at 24-hour intervals, during 4 consecutive days, under a continuous maternal oral water hydration regimen, in singleton pregnancies with isolated fetal gastroschisis. Results: Nine pregnancies were examined at a mean gestational age of 31.6 weeks (+/-1.4) and mean maternal daily oral water intake was 3,437 (+/-810) ml. Mean AFI on days 0-3 were 13.2 (+/-2.9), 14.8 (+/-3.3), 14.5 (+/-3.1) and 14.8 (+/-2.6), respectively. AFI on day 0 was significantly lower compared to all the other 3 days (p = 0.01 and 0.02). Significant correlation was found in relative difference in AFI between day 0 and day 1 and gestational age (r = -0.67, p = 0.05) and the amount of water intake in the previous 24 h (r = 0.76, p = 0.02). Conclusion: Maternal oral water hydration significantly increases AFI in pregnancies with isolated fetal gastroschisis. Copyright (C) 2010 S. Karger AG, Basel

A utilização de colóides é indicada em várias situações, mas nem sempre aplicável na clínica de eqüinos. O objetivo desse trabalho foi avaliar o uso de solução concentrada de albumina eqüina (diluída a 5%) durante fluidoterapia em eqüinos com desidratação leve a moderada, comparando-a com fluidoterapia apenas com solução fisiológica. Foram utilizados dois grupos de cinco eqüinos adultos, sem alterações clínicas. Cada animal passou pelo protocolo dos dois grupos experimentais (fluidoterapia apenas com solução fisiológica; fluidoterapia com solução de albumina eqüina e solução fisiológica). A desidratação foi induzida com duas aplicações de furosemida e jejum. Durante o experimento foram realizadas várias avaliações: pesagem; exame físico geral; hematócrito; osmolalidade plasmática; gasometria; proteína total; albumina; Na; K; débito cardíaco; pressão arterial; uréia e creatinina, e cálculo da pressão oncótica e volume plasmático. Com a aplicação da solução de albumina houve diferença em relação ao outro grupo, embora nem sempre demonstrada estatisticamente, na avaliação do turgor de pele, hematócrito, proteína total, albumina, Na plasmático, pressão arterial, débito cardíaco...

O progresso científico e tecnológico das últimas décadas registra um avanço significativo no processo de obtenção da cal, porém, há uma lacuna de conhecimento de base referente à sua ação quando empregada em conjunto com o cimento Portland. O uso da cal nas argamassas mistas de acabamento tem sido associado positivamente apenas à plasticidade no estado fresco e à sua deformabilidade no estado endurecido. Maiores informações são necessárias sobre a ação da cal na evolução das propriedades da argamassa no estado fresco, vinculadas à hidratação do cimento. Este conhecimento é importante para o desenvolvimento de formulações que atendam ao desempenho desejado em diferentes aplicações. O entendimento do mecanismo de hidratação do cimento em presença da cal constitui uma plataforma para estudos de adições minerais ativas ao clínquer, com adição de cal hidratada como fonte externa de cálcio, na produção de novos materiais cimentícios sustentáveis. O estudo em pasta realizado teve como foco a interação cimento-cal visando identificar os fenômenos químicos e físicos relevantes que se sucedem à adição de água ao sistema. Foram caracterizadas as idades iniciais de hidratação do cimento por meio de ensaios de calorimetria de condução...

The objective of this study was to determine the effect of maternal hydration with oral isotonic solution and water on the amniotic fluid (AF) index of women with normohydramnios. Women with a normal AF index and gestational age between 33 and 36 weeks without maternal complications were randomized into three groups [isotonic solution (Gatorade®), water, control]. The isotonic solution and water groups were instructed to drink 1.5 L of the respective solution and the control group was instructed to drink 200 mL water over a period of 2 to 4 h. AF index was measured before and after hydration by Doppler ultrasonography. The investigator performing the AF index measurement was blind to the subject’s group. Ninety-nine women completed the study without any adverse maternal effects. The median increase in AF index after hydration was significantly greater for the isotonic solution and water groups than for the control group. There was no significant difference between the isotonic solution and water groups. Hydration with isotonic solution and water caused a 10-fold (95%CI: 2.09-49.89) and 6-fold (95%CI: 1.16-30.95) increase in the chance of a 20% increase of AF index, respectively. Maternal hydration with isotonic solution or water increased the AF index in women with normohydramnios.

The aim of the present study was to determine the effect of volume and composition of fluid replacement on the physical performance of male football referees. Ten referees were evaluated during three official matches. In one match the participants were asked to consume mineral water ad libitum, and in the others they consumed a pre-determined volume of mineral water or a carbohydrate electrolyte solution (6.4% carbohydrate and 22 mM Na+) equivalent to 1% of their baseline body mass (half before the match and half during the interval). Total water loss, sweat rate and match physiological performance were measured. When rehydrated ad libitum (pre-match and at half time) participants lost 1.97 ± 0.18% of their pre-match body mass (2.14 ± 0.19 L). This parameter was significantly reduced when they consumed a pre-determined volume of fluid. Sweat rate was significantly reduced when the referees ingested a pre-determined volume of a carbohydrate electrolyte solution, 0.72 ± 0.12 vs 1.16 ± 0.11 L/h ad libitum. The high percentage (74.1%) of movements at low speed (walking, jogging) observed when they ingested fluid ad libitum was significantly reduced to 71% with mineral water and to 69.9% with carbohydrate solution. An increase in percent movement expended in backward running was observed when they consumed a pre-determined volume of carbohydrate solution...

The Reynolds–Anmatjira Ranges, central Australia, form part of a high-grade basement terrane dissected by intensely metasomatized transpressional shear zones active during the Ordovician–Carboniferous Alice Springs Orogeny. Unlike typical retrograde structures associated with discrete fluid flow, the mid-crustal setting and intracontinental nature of these shear systems present significant problems for the source and ingress mechanism of the fluid involved in their rehydration. To address these issues, we describe two detailed traverses across deformed and metasomatized basement rocks in this region, and interrogate their record of fluid–rock interaction from various perspectives. Both traverses combine structural and petrological observations with Zr-in-rutile and Ti-in-quartz thermobarometry, oxygen and hydrogen stable isotope analysis, and major, trace and rare earth element mobility trends. Each technique is critically evaluated for its utility in this study and its more widespread applicability to alternative field areas, providing a strategic framework for the general investigation of fluid-affected shear zones. Ultimately, the integrated data sets specify pressure–temperature conditions of ∼530 °C and 4–5 kbar, implying average apparent thermal gradients of 29–36 °C km−1 and depths of 14–18 km. Other characteristic features to emerge include strongly variable element mobilities and pronounced isotopic depletion fronts consistent with the alteration effects of an externally derived...

Fragestellung: Flüssigkeitszufuhr ist eine weitverbreitete Methode, um einen Abfall der Glomerulären Filtrationsrate (GFR) nach Kontrastmittelgabe (KM) entgegenzuwirken. Bislang gab es aber noch keine kontrollierte Studie bezüglich der Effektivität und Eignung unterschiedlicher Applikationsschemata. Methoden: 38 Patienten mit einer normalen, bzw. leicht eingeschränkten Nierenfunktion die im Rahmen einer elektiven angiographischen Untersuchung mindestens 80 ml KM erhielten, wurden für eine der folgenden Behandlungsgruppen mit jeweils unterschiedlicher Hydratation randomisiert: Gruppe 1: Volumenexpansion mit 300 ml hypoosmolarer Kochsalzlösung während der KM-Gabe Gruppe 2: parenterale Gabe von 2000 ml hypoosmolarer Kochsalzlösung innerhalb von 12 Stunden vor und nach der KM-Gabe. Den Patienten beider Gruppen wurde gestattet, zusätzlich Flüssigkeit nach der Angiographie zu trinken (ca. 1500 ml). In beiden Gruppen wurde eine ausgeglichene Flüssigkeitsbilanz erzielt. Die GFR wurde mittels der KM-Clearance zum Ausgangspunkt und 48 Stunden nach Angiographie gemessen. Untersucht wurden die mittlere Veränderung der GFR 48 Stunden nach KM-Gabe und die Inzidenz der Kontrastmittelnephropathie (KMIN). Die KMIN wurde definiert als ein Abfall der GFR um 25 des Ausgangswertes 48 Stunden nach KM-Gabe. Ergebnisse: Patienten der Gruppe 1 zeigten eine signifikant (p<0...

Hintergrund Die Kontrastmittelnephropathie (KMIN) gehört zu den häufigsten Ursachen eines im Krankenhaus erworbenen Nierenversagens. Als eine effektive und kostengünstige Prophylaxe der KMIN gilt zwischenzeitlich eine ausreichende Hydrierung des Patienten als gesichert. Fragestellung In dieser Studie wurde die Effektivität einer präventiven oralen Hydrierung mit einer intravenösen Bolusgabe von 300ml halb-isotonischer Kochsalzlösung während der Kontrastmittelgabe, zusätzlich zu einer oralen Prehydrierung, hinsichtlich des Auftretens einer KMIN verglichen. Methoden 46 Patienten mit normaler oder leicht eingeschränkter Nierenfunktion, die im Rahmen einer elektiven Herzkatheteruntersuchung mindestens 80ml eines nieder-osmolaren Kontrastmittels erhielten, wurden in eine der folgenden Hydratationsgruppen randomisiert: Gruppe 1: orale Prehydrierung mit insgesamt 3000ml Flüssigkeit (Tee, Mineralwasser) vom Vorabend bis zwei Stunden vor der Untersuchung, sowie zwei Stunden nach der Untersuchung bis zum Abend des selben Tages. Gruppe 2: orale Prehydrierung mit insgesamt 2700ml Flüssigkeit (Tee, Mineralwasser) am Vorabend, sowie zwei Stunden nach der Untersuchung bis zum Abend. Zusätzliche Gabe von 150ml NaCl 0,9% und 150ml Glukose 5% während der Kontrastmittelapplikation. Mittels der Kontrastmittel-Clearance wurde die glomeruläre Filtrationsrate (GFR) zur Kontrastmittelgabe und 48 Stunden nach der Untersuchung bestimmt.

Hydration should be considered before, during and after the exercise. This review intends to approach the main points of hydration process in soccer. The replacement of fluids during exercise is proportional to some factors, such as: exercise intensity; climatic conditions; the athlete's acclimatization; the athlete's physical conditioning; physiologic individual characteristics and the player's biomechanics. Performance is improved when players ingest not only water but also carbohydrate. The rates that carbohydrate and water are absorbed by the organism are limited by the rates of gastric emptying and intestinal absorption. The composition of drinks offered to the players should be influenced by the relative importance of the need of supplying carbohydrates or water; it should be remembered that the depletion of carbohydrate can result in fatigue and decrease of performance, but it is not usually a life-threatening condition. The addition of carbohydrate in these drinks increases the concentrations of blood glucose, increases the use of external fuel through the increase of the glucose oxidation in the muscles and it spares muscle glycogen. So, the ingestion of carbohydrate before and during the exercise can delay the emergence of fatigue and increase the players' performance. Several tactics can be used to avoid dehydration...

AIM: To investigate whether oral motor performance is determinant for the hydration status and the effect of a supplemental oral fluid supply on salivary osmolality. METHODS: The sample consisted of 99 children with cerebral palsy aged 6 to 13 years old. In this study, children participated in 2-day evaluations: 1st day - baseline: saliva collection, caries experience and oral motor performance evaluations; and 2nd day: saliva collection after supplemental fluid supply. Prior to each evaluation, the participants were trained for saliva collection. Unstimulated whole saliva was collected using cotton roll at baseline, with the amount of fluid usually offered by caregivers, and 48 h after baseline, with as much as twice the normal daily fluid intake previously offered. Salivary osmolality was measured using a freezing point depression osmometer. Caries experience index for decayed, missed and filled teeth (DMFT) was evaluated. According to the Oral Motor Assessment Scale, the children were classified into subfunctional or functional groups. Chi-square, Student's t test and Pearson's correlation coefficient were used. RESULTS: The subfunctional group presented a higher percentage of quadriplegic children (p<0.001), with significantly higher values for caries experience (p<0.001) and salivary osmolality (p<0.001)...

RATIONALE, AIMS AND OBJECTIVES: This study aimed to describe (1) how thickened fluids are supplied to clients with dysphagia; (2) how clients' consumption of thickened fluids and hydration status is monitored; and (3) the impact of institutional factors on thickened fluid intake and hydration in Australian health care settings. METHODS: Speech pathologists, dietitians and nurses working in Australian health care settings were asked to voluntarily participate in an online survey that was advertised through their respective professional associations. The questions required a self-report of their practice with respect to thickened fluids. RESULTS: Few health care facilities (17%) monitored thickened fluid consumption routinely even though, in the opinion of 51% the respondents, clients on thickened fluids at their facility do not drink enough. Palatability of the thickened fluid products and patients' dependence on others for drinking were thought to have a major impact on fluid intake. Respondents also highlighted institutional factors such as inadequate assistance from staff and inconsistent systems for monitoring fluid intake and signs of dehydration. The most common way to address inadequate intake was for nurses to 'push fluids' (87%). Free water protocols were used only 14% of the time and setting small oral fluid targets throughout the day was the least common strategy (11%). CONCLUSIONS: There is a need for Australian health care facilities to educate all clinical staff about the risks of dehydration and develop clinical pathways for clients with dysphagia...

This is the final version of the article. It first appeared from Elsevier via http://dx.doi.org/10.1016/j.epsl.2015.07.071; We studied one cycle (Cycle 6) of gypsum-marl deposition from the Messinian Yesares Member in Sorbas Basin, Spain. The objective was to reconstruct the changing environment of deposition and its relation to astronomically-forced climate change. The ?1818O and ?D of gypsum hydration water (CaSO4?2H2O) and salinity of fluid inclusions were measured in the same samples to test if they record the composition of the mother fluid from which gypsum was precipitated. Water isotopes are highly correlated with fluid inclusion salinity suggesting the hydration water has not exchanged after formation. The relatively low water isotope values and fluid inclusion salinities indicate a significant influence of meteoric water, whereas ?34S, ?18OSO4 26 and 87Sr/86Sr support a dominant marine origin for the gypsum deposits. The discrepancy between water and elemental isotope signatures can be reconciled if meteoric water dissolved previously deposited marine sulfates supplying calcium and sulfate ions to the basin which maintained gypsum saturation. This recycling process accounts for the marine ?34S, ?18OSO4 and 87Sr/86Sr signatures...

Variation in systemic hydration status, namely chronic systemic hypohydration or dehydration, can influence the development of several chronic non-ophthalmic diseases. Owing to the eye's high water content and unique system of fluid regulation, we hypothesized that hydration status may affect the eye in health and disease states. Therefore, we performed a systematic review of the current evidence implicating changes in hydration and their association with ocular physiology and morphological characteristics. We also reviewed relevant clinical correlations of changes in hydration and major common eye diseases. Our findings suggest that systemic hydration status broadly affects a variety of ocular pathophysiologic processes and disease states. For example, dehydration may be associated with development of dry eye syndrome, cataract, refractive changes and retinal vascular disease. On the other hand, excessive hydration is associated with some ocular diseases. Tear fluid osmolarity may be an effective marker of systemic hydration status. Recent studies implicate chronic renin-angiotensin-aldosterone system activation in the pathogenesis of diabetic retinopathy and glaucoma but also suggest its antagonism may be a useful therapeutic target. Our findings indicate that assessment of hydration status may be an important consideration in the management of patients with chronic eye diseases and undergoing eye surgery. Further research investigating the role of acute and chronic changes in hydration in individuals with and without ocular disease is warranted.; Justin C Sherwin...

peer-reviewed; The effectiveness of 0.1% fat milk (M) at restoring fluid balance after exercise and heat induced hypohydration was compared to a commercially available carbohydrate-electrolyte (CE) sports drink and water (W) using a metered rate of fluid ingestion. After losing 2.1 (0.2) % body mass, participants (n = 7) consumed a drink volume equivalent to 150% of their body mass loss, over a period of 2.5-3 hours. A metered rate of fluid ingestion was chosen as it is widely acknowledged that rapid ingestion (< 60 min) of a large volume of fluid (>1000ml) can over-stimulate diuresis. Blood and urine samples were collected before and for 5 hours after exercise-induced loss of body mass. Mean plasma osmolality was higher in the M trial 289 (3) mOsmol/kg compared to W 286 (3) mOsmol/kg and CE 287 (3) mOsmol/kg, during this 5 hour period (p = 0.021). Indicative of a reduced diuretic response, urine volume was lower and urine osmolality higher in the M trial compared with CE and W. Total urine volume during the M trial was 774 (92) mL compared to CE 1314 (434) mL and W 1429 (345) mL (p = 0.023). A net positive fluid balance from 2h to 5h was achieved in the M trial, whereas the CE and W trials returned to net negative balance by the end of the 5h rehydration period. Final net fluid balance in the M trial was 117 (122) mL compared to CE -381 (460) mL and W trials -539 (390) mL (p = 0.049). This represents a final relative net fluid balance of 5.9 (5.9) % in the M trial compared with CE -22.7 (23.3) % (p = 0.048) and W - 30.9 (22.7) % (p = 0.012).

http://dx.doi.org/10.5007/1980-0037.2009v11n2p202 The aim of this study was to investigate fluid replacement strategies of young soccer players and their level of knowledge regarding hydration management. A total of 216 males (age: 18 ± 0.9 years) playing soccer for 8.7 ± 2.6 years were studied. The participants were members of four elite and subelite Brazilian soccer clubs. An exploratory descriptive study was conducted using a self-administered questionnaire consisting of 18 objective questions. The main results indicated that 32.3% and 30.1% of the athletes do not have an appropriate strategy for fluid replacement during competitions and training, respectively. In addition, 1.4% and 4.6% of the subjects reported to ingest no fluids during these exercise conditions. When asked about the type of solution (water or isotonic solution) consumed before, during and after exercise, water was the main fluid ingested during these periods. Approximately 80 athletes only ingest fluids when feeling thirsty. Coca-Cola® accounted for 11.1% of ingested fluids. Only 27.8% of the participants measure their body weight and 54.2% were unaware of the adequate strategy for fluid replacement. The most common symptoms reported by the athletes were cramps (53.2%)...

Introduction: There is scarce and inconsistent information about gender-related differences in the hydration of sports persons, as well as about the effects of hydration on performance, especially during indoor sports. Objective: To determine the physiological differences between genders during in indoor physical exercise, with and without hydration. Methods: 21 spinning sportspeople (12 men and 9 women) participated in three controlled, randomly assigned and non-sequential hydration protocols, including no fluid intake and hydration with plain water or a sports drink (volume adjusted to each individual every 15 min), during 90 min of spinning exercise. The response variables included body mass, body temperature, heart rate and blood pressure. Results: During exercise without hydration, men and women lost ~2% of body mass, and showed higher body temperature (~0.2ºC), blood pressure (~4 mmHg) and heart rate (~7 beats/min) compared to exercises with hydration. Body temperature and blood pressure were higher for men than for women during exercise without hydration, differences not observed during exercise with hydration. Between 42-99% of variance in body temperature, blood pressure and heart rate could be explained by the physical characteristics of subjects and the work done. Conclusions: During exercise with hydration (either with water or sport drink)...

Introduction: An adequate hydration is critical for a series of body functions, including proper regulation of core body temperature, elimination of waste metabolites by the kidney and maintenance of normal physical and cognitive functions. Some institutions have set recommendations for adequate intake of water, but these recommendations vary widely. Objective: To estimate the usual daily consumption of fluids (water and all other beverages) by a selective sample of Mexican population. Methods: Cross-sectional sample of 1,492 male and female adults between 18-65 years of age, drawn from 16 cities throughout Mexico. Self-reported fluid intake data collected over a 7-day consecutive period, recording intake of water, milk and derivatives, hot beverages, sugar sweetened beverages (SSB), alcoholic beverages and others. Results: We found that 87.5% of adult males and 65.4% of adult females reported drinking below their recommended daily fluid intake (3 L for males and 2 L for females), and in 80% of the population SSB, not including hot beverages or milk and derivatives, accounted for a larger amount and proportion of fluid intake than plain water. Sixty-five percent of adult males and 66% of adult females consumed more than 10% of their estimated daily caloric intake from fluids. Fluid intake did not differ significantly by gender...

Objectives. To estimate the water balance in a healthy population of sportspeople from Southern Spain and determine the sources of their fluid intake, evaluating the contribution of different types of drink and comparing the results by sex and province of residence. Methods. Three hundred eighty-six sportspeople (231 males, 152 females) were enrolled in the study. A questionnaire was administered to calculate nutrient intake through diet and physical activity, and anthropometric measures were taken according to ISAK standards. SPSS-15 was used for data analyses. Results. Fruit juice, tap water, bottled water, processed fruit juice, carbonated drinks, and isotonic drinks comprised 96% of the total water intake. Simple sugar consumption represented 4.44% of daily calorie intake. Significant differences were found between sexes and between professionals and amateurs. The amount of drinks consumed varied as a function of the quality of the drinking water, which significantly differed among the eight Andalusian provinces. Conclusion. This study population did not fully meet fluid intake recommendations, compliance with hydration recommendations varied as a function of the sex and the amateur or professional status of these sportspeople. The pattern of drinks consumption also differed according to their place of residence.

Introduction: Fluid intake is difficult to monitor. Biomarkers of beverage intake are able to assess dietary intake / hydration status without the bias of self-reported dietary intake errors and also the intra-individual variability. Various markers have been proposed to assess hydration, however, to date; there is a lack of universally accepted biomarker that reflects changes of hydration status in response to changes in beverage intake. Aim: We conduct a review to find out the questionnaires of beverage intake available in the scientific literature to assess beverage intake and hydration status and their validation against hydration biomarkers. Methods: A scientific literature search was conducted. Only two articles were selected, in which, two different beverage intake questionnaires designed to capture the usual beverage intake were validated against Urine Specific Gravidity biomarker (Usg). Results: Water balance questionnaire (WBQ) reported no correlations in the first study and the Beverage Intake Questionnaire (BEVQ), a quantitative Food frequency questionnaire (FFQ) in the second study, also found a negative correlation. FFQ appears to measure better beverage intake than WBQ when compared with biomarkers. However, the WBQ seems to be a more complete method to evaluate the hydration balance of a given population. Conclusions: Further research is needed to understand the meaning of the different correlations between intake estimates and biomarkers of hydration in distinct population groups and environments.

Salivary osmolality reflects the hydration status of individuals with cerebral palsy necessary for adequate unstimulated salivary flow rate. Aim: To investigate whether oral motor performance is determinant for the hydration status and the effect of a supplemental oral fluid supply on salivary osmolality. Methods: The sample consisted of 99 children with cerebral palsy aged 6 to 13 years old. In this study, children participated in 2-day evaluations: 1st day - baseline: saliva collection, caries experience and oral motor performance evaluations; and 2nd day: saliva collection after supplemental fluid supply. Prior to each evaluation, the participants were trained for saliva collection. Unstimulated whole saliva was collected using cotton roll at baseline, with the amount of fluid usually offered by caregivers, and 48 h after baseline, with as much as twice the normal daily fluid intake previously offered. Salivary osmolality was measured using a freezing point depression osmometer. Caries experience index for decayed, missed and filled teeth (DMFT) was evaluated. According to the Oral Motor Assessment Scale, the children were classified into subfunctional or functional groups. Chi-square, Student’s t test and Pearson’s correlation coefficient were used. Results: The subfunctional group presented a higher percentage of quadriplegic children (p<0.001)...
