Article Abstract
Purpose: Maintaining the proper fluid balance is a fundamental step in the management of hospitalized patients. The current study evaluated the impact of negative fluid balance on outcomes of patients with confirmed COVID-19.
Methods: We considered the negative fluid balance as a higher output fluid compared to the input fluid. The fluid balance was categorized into four groups (group 4: -850 to -500 ml/day; group 3: -499 to -200 ml/day, group 2: -199 to 0 ml/day, and group 1 : 1 to 1000 ml/day) and included ordinally in the model. The outcomes were all-cause mortality, length of hospitalization, and improvement in oxygen saturation.
Results: The fluid balance differed significantly among nonsurvivors and survivors (MD: -317.93, 95% CI: -410.21, -225.69, and < 0.001). After adjusting for potential confounders, there was a significantly lower frequency of mortality in patients with negative fluid balance compared to the controls (aRR: 0.69, 95% CI: 0.57, 0.84, and < 0.001). Similarly, the length of hospitalization was significantly shorter in the negative fluid balance group in comparison to the control group (aMD: -1.01, 95% CI: -1.74, -0.28, and =0.006).
Conclusion: We determined that the negative fluid balance was associated with favorable outcomes in COVID-19 patients. The negative fluid balance was associated with the reduced mortality rate and length of hospitalization as well as improvement in oxygen saturation. Moreover, the NT-proBNP >781 pg/mL and fluid balance >-430 mL might be the predictors for positive fluid balance and mortality, respectively.

CFD Evaluation of Far-UVCand Air Cleaning Technologies in Classrooms without Mechanical Ventilation.

Far-UVC systems and air cleaners are effective strategies for controlling airborne pathogen transmission, particularly in densely occupied spaces with insufficient ventilation, such as school classrooms. This study evaluates the disinfection performance and ozone (O) formation of different far-UVC systems and air cleaners in a standard-sized classroom using computational fluid dynamics (CFD) simulation. Results show that ceiling-mounted far-UVC systems reduce airborne pathogen exposure by up to 30 % more than upper-room and wall-mounted configurations, based on intake fractions and room-average concentrations.

Aims: Intestinal ischemia-reperfusion (II/R) injury predominantly causes acute lung injury (ALI), and in severe instances, acute respiratory distress syndrome, both associated with high mortality. Electroacupuncture (EA) excels in regulating autonomic nervous system balance and safeguarding organ function. This study delved into EA's impacts and mechanisms on II/R-induced ALI.

September 2025
Background: Hyaluronic acid (HA) is a key component naturally present in the skin and is commonly used in skincare formulations and dermal fillers. Recently, there has been growing interest in oral HA supplementation for maintaining skin health and preventing aging due to its potential systemic benefits.
Objective: This study aims to provide a comprehensive analysis of the efficacy of oral HA supplementation on various skin parameters, including hydration, elasticity, firmness, wrinkle reduction, and transepidermal water loss.
Driving a Stimuli-Responsive Wedge in the Packing of Phospholipid Membranes Using Bolaamphiphile Intercalants.

Bolaamphiphiles─amphiphilic molecules with polar groups at each of the two ends of a hydrophobic tail with pH-sensitive spontaneous molecular curvatures, endow membranes of extremophiles with an exquisite balance between stability (or robustness) and adaptability (or plasticity). But how the presence (or real-time insertion) of bolaamphiphiles influences lamellar lipid membranes is poorly understood. Using a combination of time-resolved confocal fluorescence microscopy, in situ small-angle X-ray and neutron scattering (SAXS and SANS), and neutron spin echo (NSE) measurements, we monitor here the pH-dependent interactions of nanoscopic vesicles of a representative bolaamphiphile─a glucolipid consisting of a single glucose headgroup and a C18:1 (oleyl) fatty acid tail (G-C18:1)─with the membranes of an essentially cylindrical fluid-phase phospholipid (dioleoylphosphatidylcholine, DOPC).
