Abstract Studies on length of stay (LOS) per total body surface area (TBSA) burn in pediatric patients are often limited to single institutions and are grouped in ranges of TBSA burn which lacks specific detail to counsel patients and families. A LOS to TBSA burn ratio of 1 has been widely accepted but not validated with multi-institution data. The objective of this study is to describe the current relationship of LOS per TBSA burn and LOS per TBSA burn relative to burn mechanism with the use of multi-institutional data. Data from the Pediatric Injury Quality Improvement Collaborative (PIQIC) were obtained for patients across five pediatric burn centers from July 2018-September 2020. LOS per TBSA burn ratios were calculated. Descriptive statistics and generalized linear regression which modeled characteristics associated with LOS per TBSA ratio are described. Among the 1267 pediatric burn patients, the most common mechanism was scald (64%), followed by contact (17%) and flame (13%). The average LOS/TBSA burn ratio across all cases was 1.2 (SD 2.1). In adjusted models, scald burns and chemical burns had similar LOS/TBSA burn ratios of 0.8 and 0.9, respectively, while all other burns had a significantly higher LOS/TBSA burn ratio (p<0.0001). LOS/TBSA burn ratios were similar across races, although Hispanics had a slightly higher ratio at 1.4 days. These data establish a multi-institution LOS per TBSA ratio across PIQIC centers and demonstrate significant variation in the LOS per TBSA burn relative to the burn mechanism sustained.

Abstract Introduction Studies on length of stay (LOS) per total body surface area (TBSA) burn in pediatric patients have been performed at single institutions and based on ranges of TBSA burn. A LOS to TBSA burn ratio of 1:1 has also been widely accepted but not confirmed over time across numerous institutions. The objective of this study was to use multi-institutional pediatric burn data to describe benchmarks associated with LOS per TBSA burn. Methods Data from the Pediatric Injury Quality Improvement Collaborative (PIQIC) were obtained for 1004 patients (n=1004) treated at five pediatric burn centers from July 2018-March 2020. LOS/TBSA burn ratios were calculated for each site. LOS/TBSA burn by institution and mechanism were analyzed. Generalized linear regression models were used to model the effect of hospital and burn mechanism on the LOS/TBSA ratio. Results Among the 1004 injuries, the most common burn mechanism was by scald (64%), followed by contact (16%) and flame (13%). The average LOS/TBSA burn ratio across all cases was 1.3 days (SD 2.2). Flame burns had a higher LOS/TBSA burn ratio than scald burns with a mean LOS/TBSA burn of 1.63 compared to 0.84. In adjusted models, scald burns, and chemical burns had the lowest LOS/TBSA burn ratio and electrical and friction burns had the highest LOS/TBSA burn ratio. The LOS/TBSA burn ratio was comparable across hospitals after adjustment for mechanism, with just Hospital 4 having a lower average LOS/TBSA burn of 0.49 days. Conclusions These data establish a multi-institutional ratio for the overall performance in LOS for pediatric burn patients. A LOS per TBSA ratio of about 1 was observed across PIQIC centers, except for a lower ratio at one center. Additionally, it provides evidence on the variance in LOS per TBSA burn relative to the sustained burn mechanism. Further collaborative data analysis will allow us to recognize specific patterns and outcomes in pediatric burn care, which is essential for the implementation of quality improvement standards.

The performance of most oxidation resistant alloys and coatings is markedly improved if the oxide scale strongly adheres to the substrate surface. Consequently, in order to develop alloys and coatings with improved oxidation resistance, it has become necessary to determine the conditions that lead to spallation of oxides from the surfaces of alloys. In what follows, the morphological features of nonadherent Al2O3, and the substrate surfaces from which the Al2O3 has spalled, are presented and related to oxide spallation.The Al2O3, scales were developed by oxidizing Fe-25Cr-4Al (w/o) and Ni-rich Ni3 (Al,Ta) alloys in air at 1200°C. These scales spalled from their substrates upon cooling as a result of thermally induced stresses. The scales and the alloy substrate surfaces were then examined by scanning and replication electron microscopy.The Al2O3, scales from the Fe-Cr-Al contained filamentary protrusions at the oxide-gas interface, Fig. 1(a). In addition, nodules of oxide have been developed such that cavities were formed between the oxide and the substrate, Fig. 1(a).

Characterization Of Materials

Essential to the characterization of materials using analytical electron microscopy (AEM) techniques is the specimen itself. Without suitable samples, detailed microstructural analysis is not possible. Ultramicrotomy, or diamond knife sectioning, is a well-known mechanical specimen preparation technique which has been gaining attention in the materials science area. Malis and co-workers and Glanvill have demonstrated the usefulness and applicability of this technique to the study of a wide variety of materials including Al alloys, composites, and semiconductors. Ultramicrotomed specimens have uniform thickness with relatively large electron-transparent areas which are suitable for AEM anaysis.Interface Analysis in Type 316 Austenitic Stainless Steel: STEM-EDS microanalysis of grain boundaries in austenitic stainless steels provides important information concerning the development of Cr-depleted zones which accompany M23C6 precipitation, and documentation of radiation induced segregation (RIS). Conventional methods of TEM sample preparation are suitable for the evaluation of thermally induced segregation, but neutron irradiated samples present a variety of problems in both the preparation and in the AEM analysis, in addition to the handling hazard.

Hemocyanin, the respiratory pigment of the scorpion Androctonus australis is composed of 24 kidney shaped subunits. A model of architecture supported by many indirect arguments has been deduced from electron microscopy (EM) and immuno-EM. To ascertain, the disposition of the subunits within the oligomer, the 24mer was submitted to three-dimensional reconstruction by the method of single-exposure random-conical tilt series.A sample of native hemocyanin, prepared with the double layer negative staining technique, was observed by transmisson electron microscopy under low-dose conditions. Six 3D-reconstructions were carried out indenpendently from top, side and 45°views. The results are composed of solid-body surface representations, and slices extracted from the reconstruction volume.The main two characters of the molecule previously reported by Van Heel and Frank, were constantly found in the solid-body surface representations. These features are the presence of two different faces called flip and flop and a rocking of the molecule around an axis passing through diagonnally opposed hexamers. Furthermore, in the solid-body surface of the top view reconstruction, the positions and orientations of the bridges connecting the half molecules were found in excellent agreement with those predicted by the model.
