Isolated sacral injuries: Postoperative length of stay, complications, and readmission

World Journal of Orthopedics 2015年第8期6卷 629-635页

AIM: to investigate inpatient length of stay(LOS), complication rates, and readmission rates for sacral fracture patients based on operative ***: All patients who presented to a large tertiary care center with isolated sacral fractures in an 11-year period were included in a retrospective chart review. Operative approach(open reduction internal fixation vs percutaneous) was noted, as well as age, gender, race, and American Society of Anesthesiologists' score. Complications included infection, nonunion and malunion, deep venous thrombosis, and hardware problems; 90-d readmissions were broken down into infection, surgical revision of the sacral fracture, and medical complications. LOS was collected for the initial admission and readmission visits if applicable. Fisher's exact and non-parametric t-tests(Mann-Whitney U tests) were employed to compare LOS, complications, and readmissions between open and percutaneous ***: Ninety-four patients with isolated sacral fractures were identified: 31(30.4%) who underwentopen reduction and internal fixation(ORIF) vs 63(67.0%) who underwent percutaneous fixation. there was a significant difference in LOS based on operative approach: 9.1 d for ORIF patients vs 6.1 d for percutaneous patients(P = 0.043), amounting to a difference in cost of $13590. ten patients in the study developed complications, with no significant difference in complication rates or reasons for complications between the two groups(19.4% for ORIF patients vs 6.3% for percutaneous patients). Eight patients were readmitted, with no significant difference in readmission rates or reasons for readmission between the two groups(9.5% percutaneous vs 6.5% ORIF).CONCLUSION: there is a significant difference in LOS based on operative approach for sacral fracture patients. Given similar complications and readmission rates, we recommend a percutaneous approach.

背景：开放复位内固定术后，在内固定物存在的情况下治疗伤口深部感染极为棘手，关于治疗方案的使用，文献报道甚少。本研究旨在探讨骨折内固定术后6周内发生感染后保留内固定物直至骨性愈合的可能性。方法：通过回顾3个I级创伤中心以往的病历和创伤登记表，共纳入121例新鲜骨折患者，这些患者术中细菌培养均为阳性，内固定术后6周内共123处创口发生感染。统计保留内固定物并获骨折愈合者的比率，评价预测其治疗成败的指标。结果：86例患者（87处骨折；71％）经手术清创、保留内固定物和敏感抗生素治疗获得骨折愈合。治疗失败的有关因素包括开放性骨折（p=0．03）和髓内钉固定（p=0．01）。其他非明显相关但有相关倾向的变量包括吸烟、假单胞菌感染以及累及股骨、胫骨、踝部或足部的骨折。结论：骨折内固定术后深部感染者可通过手术清创、敏感抗生素治疗及保留内固定物成功获得骨折愈合。这些结果可通过基于危险基因、特定菌种和有关的内固定种类对患者进行选择而获得改善。

Emerging role of A-kinase anchoring protein 5 signaling in reward circuit function

there is a strong evidence supporting the hypothesis of synaptic dysfunction as a major contributor to neural circuit and network disruption underlying emotional and mood dysregulation in psychiatric disorders(Simmons et al.,2024).Diverse sets of distinct molecular signaling pathways converge on the synapse to regulate synaptogenesis,synaptic function,and synaptic plasticity in brain regions and circuits through complex interactions organized by numerous multivalent protein scaffolds,including the family of proteins known as A-kinase anchoring proteins(AKAPs).

Granular activated carbons from palm nut shells for gold di-cyanide adsorption

引用

International Journal of Minerals,Metallurgy and Materials 2013年第2期20卷 172-179页

作者： william K.Buah Paul t.williams Energy Research Institute The University of LeedsLeeds LS2 9JTUnited Kingdom

Granular activated carbons were produced from palm nut shells by physical activation with steam. the proximate analysis of palm nut shells was investigated by thermogravimetric analysis, and the adsorption capacity of the activated carbons, produced as a result of shell pyrolysis at 600℃ followed by steam activation at 900℃ in varying activation times, was evaluated using nitrogen adsorption at 77 K. Applicability of the activated carbons for gold dicyanide adsorption was also investigated. Increasing the activation hold time with the attendant increase in the degree of carbon burn-off results in a progressive increase in the surface area of the activated carbons, reaching a value of 903.1 m2/g after activation for 6 h. the volumes of total pores, mieropores, and mesopores in the activated carbons also increase progressively with the increasing degree of carbon burn-off, resulting from increasing the activation hold time. the gold di-cyanide adsorption of the activated carbons increases with the rise of pore volume of the activated carbons. the gold di-cyanide adsorption of palm nut shell activated carbon obtained after 6-h activation at 900℃ is superior to that of a commercial activated carbon used for gold di-cyanide adsorption.

Release, Recycle, Rebuild： Cell-Wall Remodeling, Autodegradation, and Sugar Salvage for New Wall Biosynthesis during Plant Development

引用

Molecular Plant 2018年第1期11卷 31-46页

作者： william J. Barnes Charles t. Anderson Department of Biology Center for Ugnocellulose Structure and Formation the Pennsylvania State University University Park PA 16802 USA

Plant cell walls contain elaborate polysaccharide networks and regulate plant growth, development, mechanics, cell-cell communication and adhesion, and defense. Despite conferring rigidity to support plant structures, the cell wall is a dynamic extracellular matrix that is modified, reorganized, and degraded to tightly control its properties during growth and development. Far from being a terminal carbon sink, many wall polymers can be degraded and recycled by plant cells, either via direct re-incorporation by trans- glycosylation or via internalization and metabolic salvage of wall-derived sugars to produce new precur- sors for wall synthesis. However, the physiological and metabolic contributions of wall recycling to plant growth and development are largely undefined. In this review, we discuss long-standing and recent evi- dence supporting the occurrence of cell-wall recycling in plants, make predictions regarding the develop- mental processes to which wall recycling might contribute, and identify outstanding questions and emerging experimental tools that might be used to address these questions and enhance our understanding of this poorly characterized aspect of wall dynamics and metabolism.
