Summary: This study examined the rehydration process after intermittent running and found that a small degree of hypohydration remained even when subjects drank fluids ad-libitum during and after exercise. The results suggest that athletes may still experience dehydration to some extent despite fluid intake in free-living conditions.

Summary: This study examined the impact of increasing sodium content in a sports drink on plasma sodium and volume responses during prolonged exercise in the heat. The results showed that increased sodium intake led to improved plasma volume and sodium maintenance, which is beneficial for individuals engaging in prolonged exercise in hot conditions.

Summary: The study compared the effects of programmed fluid intake and thirst-driven fluid intake on prolonged cycling performance and exercise associated muscle cramps. The results showed that programmed fluid intake can increase power output during a 20 km time-trial, but there was no significant difference in the prevalence of muscle cramps of the plantar flexors between the two drinking conditions.

Summary: This article highlights misconceptions about hydration status assessment methods and the impact of water disorders on kidney disease progression. It discusses the relationship between fluid intake and the progression of various kidney diseases, assessment of hydration levels in clinical practice, and in-hospital fluid therapy. The importance of further studies to clarify these issues and establish reliable methods for assessing volemia and appropriate fluid therapy is emphasized.

Summary: This study tested the accuracy of a novel, limited-availability web application (H(2)Q (TM)) for predicting sweat rates in various sports, and found that the application demonstrated high group sweat prediction accuracy. Water planning for soccer match play showed that easily and accurately predicting sweat rates can help plan group water needs and promote optimal hydration during training and/or competition.

Summary: This study investigated the effects of consuming an isotonic beverage (IB) compared to distilled water (DW) on fluid retention and cardiac autonomic activity. The results showed that the IB group had a higher beverage hydration index and greater net fluid balance compared to the DW group. There were also differences in heart rate and heart rate variability measures between the two beverage trials. Further research is needed to explore these findings in clinical populations.

Summary: The study found that male recreational tropical native runners had lower relative fluid intake, greater relative fluid balance deficit, higher whole-body sweat rates, and sweated more sodium compared to females. The sweat profile and composition of these runners were similar to existing literature, and current fluid replacement guidelines are applicable to this population.

Summary: This study determined the prevalence of hypertonic dehydration (HD) and identified risk factors for HD in older adults. A risk score was developed to predict HD in community-dwelling Thai older adults, based on factors such as age, diabetes, and use of β-blockers.

Summary: Fluid overload (FO) in neonates is a understudied area, but recent research suggests that neonates are susceptible to developing FO, posing challenges to fluid balance. FO not only has deleterious impacts on other organ systems, but may also affect survival.

Summary: Hydration is a crucial but under-researched aspect in clinical practice, especially in older individuals. Diagnostic tools for dehydration are limited, but a holistic clinical approach and point-of-care testing of salivary osmolality may have potential clinical utility. Daily fluid requirements may be lower than previously thought for older adults, and subcutaneous hydration is a safer and easier alternative to intravenous route. Encouraging increased oral intake through frequent reminders, diverse drink options, and specific drinking vessels can lead to small improvements in short-term oral intake.

Summary: In this study, the mechanism of the PEG/K+ system inhibiting shale hydration was investigated through laboratory experiments. The inhibition performance was found to increase with higher contact angle and PEG concentration. Various analytical methods were used to explore the interaction between PEG/K+ and clay samples, confirming the inhibitory efficiency in oil field drilling.
