Meta-analysis of prophylactic hydration versus no hydration on contrast-induced acute kidney injury.

Guidelines recommend prophylactic hydration for all patients with compromised renal function undergoing contrast exposure. However, the AMACING study published recently showed a noninferior result of hydration compared with no prophylaxis in high-risk patients and led to a heat discussion. This study aimed to validate the effectiveness of prophylactic hydration in different subsets of patients undergoing a contrast procedure.

Structural study of the Fox-1 RRM protein hydration reveals a role for key water molecules in RRM-RNA recognition.

The Fox-1 RNA recognition motif (RRM) domain is an important member of the RRM protein family. We report a 1.8 Å X-ray structure of the free Fox-1 containing six distinct monomers. We use this and the nuclear magnetic resonance (NMR) structure of the Fox-1 protein/RNA complex for molecular dynamics (MD) analyses of the structured hydration. The individual monomers of the X-ray structure show diverse hydration patterns, however, MD excellently reproduces the most occupied hydration sites. Simulations of the...


Glucose and Mannose: A Link Between Hydration and Sweetness.

Glucose and mannose have a different degree of sweetness, implying different affinity to the sweet taste receptor. While the receptor structure is still undefined, there are several geometrical models for its binding mechanism. A detailed study of the hydration structure of sugars with known degree of sweetness is bound to provide information on the accuracy of such models. Our neutron dffraction study on the hydration of glucose and mannose show that both α- and β-glucose form strong hydrogen bonds with ...

Behavioral health care and technology: using science-based innovations to transform practice.

Prophylactic hydration to prevent contrast-induced nephropathy: much ado about nothing?

Clinical guidelines recommend prophylactic hydration to reduce the risk of contrast-induced nephropathy in high-risk patients, including those with chronic kidney disease. A recent single-center randomized trial showed no significant difference in the incidence of contrast-induced nephropathy in ambulatory patients with stage 3 chronic kidney disease who were randomized to no prophylactic hydration versus normal saline hydration. While these results may identify patients who are less likely to benefit from ...

Technological convergence will quickly generate disruptive innovations in oncology.

Convergence between information and communication technology and recent developments in medical care will totally change the health care sector. The way we perform diagnosis, treatment and follow-up will undergo disruptive changes in a very near future. We intend to highlight this statement by a limited selection of examples of radical innovations, especially in the field of oncology. To be totally disruptive and to illustrate the concept of "lateral power" - especially cognitive distribution - the list of ...

Observation of the Global Dynamic Collectivity of a Hydration Shell Around Apomyoglobin.

Protein surface hydration is critical to its structural properties and biological activities. However, it is still unknown whether the hydration shell is intrinsically connected and how its fluctuations dynamically interact with protein motions. Here, by selecting five site-specific locations with distinctly different environments around apomyoglobin surface, we used a tryptophan scan with femtosecond fluorescence spectroscopy and simultaneously detected hydration-water dynamics and tryptophan sidechain rel...

Bioelectrical impedance vector analysis (BIVA) for measuring the hydration status in young elite synchronized swimmers.

The assessment of body hydration is a complex process, and no measurement is valid for all situations. Bioelectrical impedance vector analysis (BIVA) has emerged as a relatively novel technique for assessing hydration status in sports. We applied BIVA a) to determine hydration changes evoked by an intense synchronized swimming (SS) training session; b) to characterize the sample of young elite swimmers in relation with a nonathletic reference population; and c) to generate its 50%, 75% and 95% percentiles o...

Anion layering and steric hydration repulsion on positively charged surfaces in aqueous electrolytes.

The molecular structure at charged solid/liquid interfaces is vital for many chemical or electrochemical processes, such as adhesion, catalysis or the stability of colloidal dispersions. How cations influence structural hydration forces and interactions across negatively charged surfaces have been studied in great detail. However, how anions influence structural hydration forces on positively charged surfaces is much less understood. Here we report force versus distance profiles on freshly cleaved mica usin...

Effect of Nano-SiO₂ on the Early Hydration of Alite-Sulphoaluminate Cement.

The impact of nano-SiO₂ on the early hydration properties of alite-sulphoaluminate (AC$A) cement was investigated with a fixed water to solid ratio (w/s) of one. Nano-SiO₂ was used in partial substitution of AC$A cement at zero, one and three wt %. Calorimetry, X-ray diffraction (XRD), thermogravimetric/derivative thermogravimetric (TG/DTG), mercury intrusion porosimetry (MIP) and scanning electron microscopy (SEM) analyses were used to characterize the hydration and hydrates of the blended cement. The ...

Hydration and cooling practices among farmworkers in Oregon and Washington.

Although recommendations for preventing occupational heat-related illness among farmworkers include hydration and cooling practices, the extent to which these recommendations are universally practiced is unknown. The objective of this analysis was to compare hydration and cooling practices between farmworkers in Oregon and Washington.

Quantitative Temperature Dependence of the Microscopic Hydration Structures Investigated by Ultraviolet Photodissociation Spectroscopy of Hydrated Phenol Cations.

To discuss the temperature effect on microscopic hydration structures in clusters, relative populations of the isomers having different hydration structures at well-defined temperatures are quite important. In the present study, we measured ultraviolet photodissociation spectra of the temperature-controlled hydrated phenol cation, [PhOH(H2O)5](+), trapped in the 22-pole ion trap. Two isomers having a distinct hydration motif with each other are identified in the spectra and a clear change in the relative po...

Mapping Hydration Dynamics Around a β-Barrel Protein.

Protein surface hydration is fundamental to its structure, flexibility, dynamics and function, but it has been challenging to disentangle their ultimate relationships. Here, we report our systematic characterization of hydration dynamics around a β-barrel protein, rat liver fatty acid-binding protein (rLFABP), to reveal the effect of different protein secondary structures on hydration water. We employed a tryptophan scan to the protein surface one at a time and examined total 17 different sites. We observe...

CO2 Hydration Shell Structure and Transformation.

The hydration-shell of CO2 is characterized using Raman multivariate curve resolution (Raman-MCR) spectroscopy combined with ab initio molecular dynamics (AIMD) vibrational density of states simulations to validate our assignment of the experimentally observed high-frequency OH band to a weak hydrogen bond between water and CO2. Our results reveal that while the hydration-shell of CO2 is highly tetrahedral, it is also occasionally disrupted by the presence of entropically stabilized defects associated with ...

Protein hydration: investigation of globular protein crystal structures.

The positions of water molecules have been analyzed in high quality protein X-ray crystal structures. About 70% of these water molecules are in contact with protein atoms at the protein surface and constitute the first hydration layer. About 20% of them are close to the first hydration layer but are not in contact with protein atoms and constitute the second hydration layer. The rest of the water molecules are either buried in the protein core or close to hetero-atoms (inorganic ions and small organic molec...

Revival of the Intermolecular Nuclear Overhauser Effect for Mapping Local Protein Hydration Dynamics.

The highly heterogeneous hydration dynamics of protein-water interfaces is considered important for protein stability and dynamics, protein folding, enzymatic activity and even drug design. The nuclear Overhauser effect (NOE) between protein and water protons is the only experimental observable which, in principle, can provide a map of locally resolved hydration dynamics. However, its utility was questioned in various theoretical studies which emphasized the contributions of long-range NOE interactions. We ...

Successful Implementation of New Technology Using an Interdepartmental Collaborative Approach.

The implementation of new technology is vital to the success of health care organizations. New technology provides health care organizations an opportunity to obtain new patients, increase revenue, and stay competitive. In 2014, a union hospital in Southern California successfully implemented a bronchial thermoplasty program. To implement this new technology, the administration created a strategy, identified financial risks and benefits, created an implementation model, established a plan based on Lewin's c...

Shifting Focus: From Hydration for Performance to Hydration for Health.

Over the past 10 years, literature on hydration biomarkers has evolved considerably - from (de)hydration assessment towards a more global definition of biomarkers of hydration in daily life. This shift in thinking about hydration markers was largely driven by investigating the differences that existed between otherwise healthy individuals whose habitual, ad-libitum drinking habits differ, and by identifying physiological changes in low-volume drinkers who subsequently increase their water intake. Aside from...

The Adoption of Surgical Innovations at Academic Versus Nonacademic Health Centers.

The value of the health care services provided by academic health centers (AHCs) in the United States increasingly is being questioned. AHCs play a prominent role in developing new surgical innovations, including new minimally invasive techniques, which are costly up front but can lead to significant benefits like decreased morbidity and lengths of stays. This study explored the role of AHCs in the adoption of these surgical innovations as a novel measure of their value.

Weight-Averaged Anharmonic Vibrational Analysis of Hydration Structures of Polyamide 6.

Structures of polyamide 6 are investigated for different hydration levels using molecular dynamics (MD) simulations and quantum vibrational calculations. The MD simulations have shown that hydration leads to an increase in the diffusion coefficient, accompanied by a growth of water clusters in the polymer. The IR difference spectra upon hydration are calculated using a weight-averaged method incorporating anharmonicity of the potential energy surface. The predicted IR difference spectrum for the amide A ban...

Artificial Nutrition and Hydration in People With Late-Stage Dementia.

The progressive nature of dementia marks this disease as a terminal illness in the advanced stage, and palliative care rather than curative treatment is indicated. The use of feeding tubes to deliver artificial nutrition and hydration at end of life is often part of the plan of care for people with dementia. Current evidence, however, suggests that tube feeding in advanced dementia is not beneficial and the burdens of the procedure and the feedings themselves outweigh any benefits. Evidence also reveals tha...
