Background: Injury severity score, serum lactate, and shock index help the physician determine the severity of injuries present and have been shown to relate to mortality. We sought to determine if an increasing amount of packed red blood cells (PRBCs) given in the first 24hours of admission is an independent predictor of mortality and how it compares to other validated markers.

Methods: A 6-year retrospective, observational study of adult trauma patients was conducted at a level 1 trauma center.

The ready availability of public-use data from various large national complex surveys has immense potential for the assessment of population characteristics using regression models. Complex surveys can be used to identify risk factors for important diseases such as cancer. Existing statistical methods based on estimating equations and/or utilizing resampling methods are often not valid with survey data due to complex survey design features.

The Earth's surface comprises minerals diagnostic of weathering, deposition and erosion. The first continental-scale mineral maps generated from an imaging satellite with spectral bands designed to measure clays, quartz and other minerals were released in 2012 for Australia. Here we show how these satellite mineral maps improve our understanding of weathering, erosional and depositional processes in the context of changing weather, climate and tectonics.

Background: Maternal vitamin D status has been associated with bone mass of offspring in many, but not all, observational studies. However, maternal vitamin D repletion during pregnancy has not yet been proven to improve offspring bone mass in a randomised controlled trial. We aimed to assess whether neonates born to mothers supplemented with vitamin D during pregnancy have greater whole-body bone mineral content (BMC) at birth than those of mothers who had not received supplementation.

Fenestrations are pores within the liver sinusoidal endothelial cells (LSECs) that line the sinusoids of the highly vascularized liver. Fenestrations facilitate the transfer of substrates between blood and hepatocytes. With pseudocapillarization of the hepatic sinusoid in old age, there is a loss of fenestrations.

Article Synopsis
  • Genome-wide association studies suggest that the CYP17A1 gene plays a significant role in regulating blood pressure, though the specific polymorphisms involved are still unidentified.
  • Researchers sequenced the CYP17A1 gene in 60 normotensive individuals and discovered 24 known single-nucleotide polymorphisms, selecting 7 for further investigation based on their proximity to the gene's transcription start site.
  • Among these, three polymorphisms showed notable functional effects, with one polymorphism (rs138009835) strongly linked to blood pressure regulation and related to aldosterone levels, highlighting its potential impact on hypertension in the population.

Malnutrition is associated with poor clinical outcomes among hospitalized patients. However, studies linking malnutrition with poor clinical outcomes in the intensive care unit (ICU) often have conflicting findings due in part to the inappropriate diagnosis of malnutrition. We primarily aimed to determine whether malnutrition diagnosed by validated nutrition assessment tools such as the Subjective Global Assessment (SGA) or Mini Nutritional Assessment (MNA) is independently associated with poorer clinical outcomes in the ICU and if the use of nutrition screening tools demonstrate a similar association.

Partner-specific perfectionistic concerns (PC) include concern over mistakes, self-criticism, and socially prescribed perfectionism as it pertains to one's partner. The social disconnection model proposes that PC influences well-being indirectly through interpersonal problems. Thus, we hypothesized that social negativity (expressed anger, hostility, and rejection) would mediate the relationship between dyadic PC and subjective well-being.

There are two very different interpretations of the prehistory of Island Southeast Asia (ISEA), with genetic evidence invoked in support of both. The "out-of-Taiwan" model proposes a major Late Holocene expansion of Neolithic Austronesian speakers from Taiwan. An alternative, proposing that Late Glacial/postglacial sea-level rises triggered largely autochthonous dispersals, accounts for some otherwise enigmatic genetic patterns, but fails to explain the Austronesian language dispersal.

This investigation combines two independent methods of identifying crop growing conditions and husbandry practices-functional weed ecology and crop stable carbon and nitrogen isotope analysis-in order to assess their potential for inferring the intensity of past cereal production systems using archaeobotanical assemblages. Present-day organic cereal farming in Haute Provence, France features crop varieties adapted to low-nutrient soils managed through crop rotation, with little to no manuring. Weed quadrat survey of 60 crop field transects in this region revealed that floristic variation primarily reflects geographical differences.

Background: Poor participation rates are often observed in colorectal cancer (CRC) screening programs utilising faecal occult blood tests. This may be from dislike of faecal sampling, or having benign bleeding conditions that can interfere with test results. These barriers may be circumvented by offering a blood-based DNA test for screening.

Silks from the Hymenoptera aculeata (bees, wasps, ants) contain ropes with four α-helical strands, rather than the more usual two strands found, for example, in α-keratin and myosin molecules. Extensive studies of the chemical structure of the silks have shown that each of the four chains in the molecule contains a central coiled-coil rod domain. However, little progress has been made in modeling the three-dimensional structure.

Hydrogen sulphide (H2S) is an endogenous inflammatory mediator produced by cystathionine-γ-lyase (CSE) in monocytes/macrophages. To determine the role of H2S and macrophages in inflammation, we used small interference RNA (siRNA) to target the CSE gene and investigated its effect in a mouse model of acute pancreatitis. Acute pancreatitis is characterised by increased levels of plasma amylase, myeloperoxidase (MPO) activity and pro-inflammatory cytokines and chemokines in the pancreas and lung.

Cities in developing countries across Asia-Pacific are struggling to effectively manage municipal solid waste (MSW). This is especially the case in secondary cities and small towns, which often face a lack of resources and know-how. Because the waste stream in these cities is usually high in organic content (50-80%) and recyclable materials (10-20%), waste-to-resource initiatives are viable options for sustainable MSW management.
