Introduction: The skin protects against fluid and electrolyte loss. Burn injury does affect skin integrity and protection against fluid loss is lost. Thus, a systemic dehydration can be provoked by underestimation of fluid loss through burn wounds.
Purpose: We wanted to quantify transdermal fluid loss in burn wounds.
Method: Retrospective study. 40 patients admitted to a specialized burn unit were analyzed and separated in two groups without (Group A) or with (Group B) hypernatremia. Means of daily infusion-diuresis-ratio (IDR) and the relationship to totally burned surface area (TBSA) were analyzed.
Results: In Group A 25 patients with a mean age of 47 ± 18 years, a mean TBSA of 23 ± 11%, and a mean abbreviated burned severity index (ABSI) score of 6.9 ± 2.1 were summarized. In Group B 15 patients with a mean age of 47 ± 22 years, a mean TBSA of 30 ± 13%, and a mean ABSI score of 8.1 ± 1.7 were included. Statistical analysis of the period from day 3 to day 6 showed a significant higher daily IDR-amount in Group A (Group A vs. Group B: 786 ± 1029 ml vs. -181 ± 1021 ml; p<0.001) and for daily IDR-TBSA-ratio (Group A vs. Group B: 40 ± 41 ml/% vs. -4 ± 36 ml/%; p<0.001).
Conclusions: There is a systemic relevant transdermal fluid loss in burn wounds after severe burn injury. Serum sodium concentration can be used to calculate need of fluid resuscitation for fluid maintenance. There is a need of an established fluid removal strategy to avoid water and electrolyte imbalances.

Uneven of filling aggregate gradation may cause transportation problems such as pipe blockage due to segregation and stratification of filling slurry. To study the influence of aggregate gradation on the conveying performance of filler slurry, aggregate gradation experiments were carried out, rheological tests on slurries with coal gangue/aeolian sand ratios (6:4, 5:5 and 4:6) showed that appropriately increasing the proportion of aeolian sand can improve particle gradation. Computational fluid dynamics (CFD) scheme was used to simulate the pipeline transportation characteristics of the slurry under the conditions of three sets each of coal gangue/aeolian sand ratios, slurry concentrations (72%,74% and 76%), and inlet velocities (1.

Background: Vanishing white matter disease (VWMD) is a rare autosomal recessive leukoencephalopathy. It is typified by a gradual loss of white matter in the brain and spinal cord, which results in impairments in vision and hearing, cerebellar ataxia, muscular weakness, stiffness, seizures, and dysarthria cogitative decline. Many reports involve minors.

The main advantages of microneedles are precise drug delivery through human skin, minimal tissue damage and painlessness. We conducted structural analysis and skin puncture studies of hollow microneedles using ANSYS for three materials: Hafnium Dioxide (HfO), Polyglycolic acid (PGA) and Polylactic acid (PLA). Firstly, we selected three lengths, three tip diameters and three base diameters to conduct a L(3) orthogonal experiment.

Anti-dipeptidyl-peptidase-like protein 6 antibody-mediated disease is a rare autoimmune encephalitis typically presenting with diarrhoea and/or weight loss, central nervous system hyperexcitability and cognitive dysfunction. We present a case of a young woman with 10 days of diplopia and unsteadiness in the context of dysthymia and significant weight loss over 2 months. Initial examination demonstrated mixed dysconjugate nystagmus and ataxic gait.

Article Synopsis
- Elevated levels of activated complement proteins in cerebrospinal fluid (CSF) are linked to increased severity of multiple sclerosis (MS) and correlate with brain imaging and disease biomarkers.
- A study involving 239 patients analyzed various complement components and liquid biomarkers in CSF, finding specific proteins like C4a, Ba, and C3a strongly associated with accelerated brain atrophy and lesion formation.
- Results indicate that higher levels of these complement proteins are predictive of greater brain volume loss and increased development of lesions, suggesting their potential role as biomarkers for disease progression in MS.
