Burns

Burn pits are a method of open-air waste management that was common during military operations in Iraq, Afghanistan, and other regions in Southwest Asia. Veterans returning from deployment have reported respiratory symptoms, potentially from exposure to burn pit smoke, yet comprehensive assessment of such exposure on pulmonary health is lacking. We have previously shown that exposure to condensates from burn pit smoke emissions causes inflammation and cytotoxicity in mice. In this study, we explored the effects of burn pit smoke condensates on human airway epithelial cells (HAECs) to understand their impact on cellular targets in the human lung...

INTRODUCTION: Burns are tissue traumas caused by energy transfer and occur with a variable inflammatory response. The consequences of burns represent a public health problem worldwide. Inhalation injury (II) is a severity factor when associated with burn, leading to a worse prognosis. Its treatment is complex and often involves invasive mechanical ventilation (IMV). The primary purpose of this study will be to assess the evidence regarding the frequency and mortality of II in burn patients...

BACKGROUND: Improving access to mental health data to accelerate research and improve mental health outcomes is a potentially achievable goal given the substantial data that can now be collected from mobile devices. Smartphones can provide a useful mechanism for collecting mental health data from young people, especially as their use is relatively ubiquitous in high-resource settings such as the United Kingdom and they have a high capacity to collect active and passive data. This raises the interesting opportunity to establish a large bank of mental health data from young people that could be accessed by researchers worldwide, but it is important to clarify how to ensure that this is done in an appropriate manner aligned with the values of young people...

BACKGROUND: The war in Ukraine has led to a strategic reorientation of the German Armed Forces towards national and alliance defense. This has also raised the need for medical and surgical adaptation to scenarios of conventional warfare. In order to develop appropriate and effective concepts it is necessary to identify those war injuries that are associated with a relevant primary and secondary mortality and that can be influenced by medical measures (potentially survivable injuries)...

We present a systematic experimental analysis of the 1:1 complex of 2,7-diazaindole (27DAI) with water in the gas phase. The complex was characterized by using two-color-resonant two-photon ionization (R2PI), laser-induced fluorescence (LIF), single vibronic level fluorescence (SVLF), and photoionization efficiency (PIE) spectroscopic methods. The 00 0 band of the S1 ←S0 electronic transition of the 27DAI-H2 O complex was observed at 33,074 cm-1 , largely red-shifted by 836 cm-1 compared to that of the bare 27DAI...

Dear Editor, Ticks carry many diseases, bacteria, and viruses and represent a very important healthcare issue both in Croatia and globally. Although most ticks are not infected with pathogens dangerous to humans, some ticks can transmit infectious diseases with significant morbidity and mortality. This is caused by the increasing incidence of many tick-borne diseases over a growing geographical area. Many factors influence which species of ticks are present in a given geographical area, as well as the density of their population and the risk of human exposure to infected ticks...

BACKGROUND: Toxic shock syndrome (TSS) is a rare but potentially life-threatening disease caused by superantigen-producing Gram-positive bacteria such as Staphylococcus aureus and Streptococcus pyogenes. Staphylococcal TSS received special attention from 1978 to 1981, when an epidemic was observed associated with the use of hyper-absorbent tampons. Today the disease is rare and generally not related to menstruation, but can occur postpartum or in post-surgical wounds, intrauterine devices (IUDs), burns or other soft tissue injuries, mastitis or other focal infections...

Wildfires, prescribed burns, and agricultural burns all impact ambient air quality across the Western U.S.; however, little is known about how communities across the region are differentially exposed to smoke from each of these fire types. To address this gap, we quantify smoke exposure stemming from wildfire, prescribed, and agricultural burns across Washington, Oregon, and California from 2014 to 2020 using a fire type-specific biomass burning emissions inventory and the GEOS-Chem chemical transport model...

BACKGROUND: Prospective randomized trials in severely burned children have shown the positive effects of oxandrolone (OX), beta blockers (BB) and a combination of the two (BBOX) on hypermetabolism, catabolism and hyperinflammation short- and long-term post-burn. Although data on severely burned adults are lacking in comparison, BB, OX and BBOX appear to be commonly employed in this patient population. In this study, we perform a secondary analysis of an international prospective randomized trial dataset to provide descriptive evidence regarding the current utilization patterns and potential treatment effects of OX, BB and BBOX...

Thermal insulation materials with good flame-retardant properties have attracted widespread attention because of their huge application potential. Traditional petrochemical-based polymer insulation materials are flammable and have problems with environmental pollution. The microtubule structure is a perfect microstructure with excellent thermal insulation performance. In addition, the microtubule structure also has low density and high elasticity. Therefore, the microtubule structure is an important reference microstructure for the development of efficient thermal insulation materials...

OBJECTIVE: The objective of this study was to examine the prevalence of overweight/obesity and excessive gestational weight gain (GWG) among military beneficiaries and to assess associations of these risk factors with maternal/neonatal complications and substantial postpartum weight retention (PPWR). METHODS: We obtained data for 48,391 TRICARE beneficiaries who gave birth in 2018 or 2019 in the United States. We used logistic regression and ANOVA to examine relationships among overweight/obesity, GWG, maternal/neonatal complications, and substantial PPWR...

The purpose of this study was to explore the mechanism of "simmer pus and grow meat" method based on bFGF regulating WNT / β-Catenin signaling pathway. Of 100 SPF rats, 25 were randomly selected as blank group, and 75 rats were established chronic infectious wound model and divided into blank group, model group (normal saline treatment, n = 25), experimental group (purple and white ointment treatment, n = 25), and wet burn ointment group (wet burn treatment, n = 25). The wound healing rate of rats was compared...

Carbon credits, a voluntary market mechanism to reduce greenhouse gas (GHG) emissions, can incentivize climate action. We evaluate the potential and eligibility of Conservation Agriculture (CA) practices for carbon credit generation in India under Verra's VM0042 methodology. Using farmer surveys and remote sensing data, we assess the eligibility based on the following conditions: Additionality Condition (GHG emission reductions to exceed legal requirements and the weighted mean adoption rate to be < 20% of area in the baseline), Yield Penalty Condition (no > 5% decrease in crop yields), and Quantitative Adjustment Condition (reduction in chemical fertilizer use by > 5%)...

In the context of the increasing global use of ethanol biofuel, this work investigates the concentrations of ethanol, methanol, and acetaldehyde, in both the gaseous phase and rainwater, across six diverse urban regions and biomes in Brazil, a country where ethanol accounts for nearly half the light-duty vehicular fuel consumption. Atmospheric ethanol median concentrations in São Paulo (SP) (12.3 ± 12.1 ppbv) and Ribeirão Preto (RP) (12.1 ± 10.9 ppbv) were remarkably close, despite the SP vehicular fleet being ~13 times larger...

Particulate inorganic nitrogen aerosols (PIN) significantly influence air pollution and pose health risks worldwide. Despite extensive observations on ammonium (pNH4 + ) and nitrate (pNO3 - ) aerosols in various regions, their key sources and mechanisms in the Tibetan Plateau remain poorly understood. To bridge this gap, this study conducted a sampling campaign in Lhasa, the Tibetan Plateau's largest city, with a focus on analyzing the multiple isotopic signatures (δ15 N, ∆17 O). These isotopes were integrated into a Bayesian mixing model to quantify the source contributions and oxidation pathways for pNH4 + and pNO3 - ...

Despite the known link between air pollution and cause-specific mortality, its relation to chronic kidney disease (CKD)-associated mortality is understudied. Therefore, we investigated the association between long-term exposure to air pollution and CKD-related mortality in a large multicentre population-based European cohort. Cohort data were linked to local mortality registry data. CKD-death was defined as ICD10 codes N18-N19 or corresponding ICD9 codes. Mean annual exposure at participant's home address was determined with fine spatial resolution exposure models for nitrogen dioxide (NO2 ), black carbon (BC), ozone (O3 ), particulate matter ≤2...

Lumbar spinal stenosis is a clinical syndrome that affects more than 200,000 people in the United States annually. It is a common cause of chronic insidious low back pain, especially in older patient populations (mean age = 64 years). Lumbar spinal stenosis is a degenerative condition of the spine leading to narrowing in the spaces around the neurovascular bundles and the classic symptom of low back pain that radiates to the buttocks and lower extremities bilaterally. It is typically a progressive waxing and waning process that may deteriorate over years...

Corneal neovascularization (CoNV) is a sight-threatening condition affecting an estimated 1.4 million people per year, and the incidence is expected to rise. It is a complication of corneal pathological diseases such as infective keratitis, chemical burn, corneal limbal stem cell deficiency, mechanical trauma, and immunological rejection after keratoplasties. CoNV occurs due to a disequilibrium in proangiogenic and antiangiogenic mediators, involving a complex system of molecular interactions. Treatment of CoNV is challenging, and no therapy thus far has been curative...

BACKGROUND Over the past 30 years, painful reactions during magnetic resonance imaging (MRI) in tattooed individuals have been sporadically reported. These complications manifest as burning pain in tattooed skin areas, occasionally with swelling and redness, often leading to termination of the scanning. The exact cause is unclear, but iron oxide pigments in permanent make-up or elements in carbon black tattoos may play a role. Additionally, factors like tattoo age, design, and color may influence reactions...
