AIM: To characterize and compare our current series of patients to prior reports in order to identify any changes in the incidence of neurological injury related to hunting accidents in Rochester, New ***: All tree s.and-related injuries referred to our regional trauma center from september 2003 through November 2011 were reviewed. Information was obtained from the hospital's trauma registry and medical records were retrospectively reviewed for data pertaining to the ***: Fifty-four patients were identified. Ninetysix percent of patients were male with a mean age of 47.9 years(range 15-69). The mean Injury severity score was 12.53 ± 1.17(range 2-34). The average height of fall was 18.2 feet(range 4-40 feet). All patients fell to the ground with the exception of one who landed on rocks, and many hit the tree or branches on the way down. A reason for the fall was documented in only 13 patients, and included tree s.and construction(3), loss of balance(3), falling asleep(3), structural failure(2), safety harness breakage(3) or lightheadedness(1). The most common injuries were spinal fractures(54%), most commonly in the cervical spine(69%), followed by the thoracic(38%) and lumbar(21%) spine. Eight patients required operative repair. Head injuries occurred in 22%. Other systemic injuries include rib/clavicular fractures(47%), pelvic fractures(11%), solid organ injury(23%), and pneumothorax or hemothorax(19%). No patient deaths were reported. The average hospital length of stay was 6.56 ± 1.07 d. Most patients were discharged home without(72%) or with(11%) services.and 17% required rehabilitation. CONCLUsION: Falls from hunting tree s.ands are still common, with a high rate of neurological injury. Compared to a decade ago we have made no progress in preventing these neurological injuries, despite an increase in safety advances. Neurosurgeons must continue to advocate for increased safety awareness.and participate in leadership roles to improve outcom

背景与目的:因考虑到机体状态较差或机体功能的情况,低位直肠癌患者有时需避免行低位结肠肛管吻合术,此时通常可选择Hartmann术(HP)或腹会阴括约肌间切除术(inter-sphincteric abdominoperineal excision,IAPE)。目前,尚无充分数据支持何种术式最为安全并向外科医师提出关于诊疗策略的建议。本研究旨在分析两种术式相关并发症的发生率。方法:本研究是一项多中心、非随机的前瞻性研究,研究对象为接受HP术或IAPE术的患者。主要观察指标为手术相关并发症的发生率,次要观察指标包括住院时间、辅助治疗开始时机以及术后90天生活质量。结果:本研究共纳入2016年4月至2019年6月接受治疗的179例直肠癌患者,其中约2/3行HP术、1/3行IAPE术,两组并发症总发生率(HP组54%,IAPE组52%)均较高。两组手术相关并发症发生率(HP组43%,IAPE组48%)同样均较高,但组间比较差异无统计学意义。HP组盆腔脓肿总发生率为11%,其中能触及残端钉合线组高于未能触及组(15%vs.2%),而IAPE组内科相关严重并发症发生率较高(IAPE组16%vs. HP组5%)且术后90天生活质量较低。结论:本研究是一项在不适宜行一期吻合的直肠癌患者中比较HP术和IAPE术治疗情况的最大型前瞻性研究,基于两种术式相近的并发症发生率数据认为,对该类直肠癌患者可继续采用这两种术式之一进行治疗。

Burn injuries.and their treatments result in severe *** traumatic injuries that are characterized by a discrete episode of pain followed by recovery,burn-injured patients endure pain for a prolonged period that lasts through wound closure(*** pain,procedural pain,breakthrough pain,neuropathic pain and itch).Regional anesthesia,including peripheral nerve blocks.and neuraxial/epidural anesthesia,offers significant benefits to a multimodal approach in pain treatment.A‘regional-first’approach to pain management can be incorporated into the workflow of burn centers through engaging regional anesthesiologists.and pain medicine practitioners in the care of burn patients.A detailed unders.anding of peripheral nerve anatomy frames the burn clinician’s perspective when considering a peripheral nerve block/*** infra/supraclavicular nerve block provides excellent coverage for the upper extremity,while the trunk can be covered with a variety of blocks including erector spinae plane and quadratus lumborum plane *** lower extremity is targeted with fascia iliaca plane and sciatic nerve blocks for both donor and recipient *** centers that adopt regional anesthesia should be aware of potential complications.and contraindications to prevent adverse events,including management of local anesthetic toxicity and epidural *** of anticoagulation around regional anesthesia placement is crucial to prevent hematoma and nerve ***,regional anesthesia can facilitate a better patient experience and allow for early therapy and mobility goals that are hallmarks of burn care and rehabilitation.

sexual selection on color and behavior within and between cichlid populations： Implications for speciation

引用

Current Zoology 2012年第3期58卷 475-483页

sexual selection is widely viewed as playing a central role in haplochromine cichlid speciation. Hypothetically, once divergent mate preferences evolve among populations of these fishes, reproductive isolation follows.and the populations begin to behave as different species. Various studies have examined patterns of assortative mating among species.and sometimes populations, but few have examined variation in directional preferences, especially among populations of the same species. We investi- gated mate choice behavior in two populations of Labeotropheus fueUeborni, a Lake Malawi endemic. We test whether mating preferences between populations are based on the same traits.and in the same direction as preferences within populations. We examine the potential contributions of two classes of trait, color patterns.and behaviors, to reproductive isolation. When females chose between either two males of their own population, or two from another, female preferences were generally similar （for the female population） across the two contexts. Mate choice patterns differed between （female） populations for a measure of color, but only modestly for male behavior. In a separate experiment we simultaneously offered females a male of their own population and a male from a different population. In these trials, females consistently preferred males from their own population, which were also the males that displayed more frequently than their opponents, but not necessarily those with color traits suggested to be most attractive in the previous experiment. Thus directional preferences for chroma and related aspects of color may be important when females are presented with males of otherwise similar phenotypes, but may play little role in mediating assortative mating among populations with subs.antially different color patterns. A preference for male behavior could play some role in speciation if males preferentially court same-population females, as we have observed for the populations

ALDH Activity Correlates with Metastatic Potential in Primary sarcomas of Bone

引用

Journal of Cancer Therapy 2014年第4期5卷 331-338页

作者： Nicholas Greco Trevor schott Xiaodong Mu Adam Rothenberg clifford Voigt Richard L. McGough III Mark Goodman Johnny Huard Kurt R. Weiss Department of Orthopaedic surgery University of Pittsburgh Medical Center Pittsburgh USA

Osteosarcoma (Os), chondrosarcoma (CsA), and Ewings sarcoma (Es) are the most common primary malignancies of bone, and are rare diseases. As with all sarcomas, the prognosis of these diseases ultimately depends on the presence of metastatic disease. survival is therefore closely linked with the biology and metastatic potential of a particular bone tumor’s cells. Here we describe a significant correlation of aldehyde dehydrogenase (ALDH) activity and the presence/absence of dis.ant metastases in ten consecutive cases of human bone sarcomas. Additionally, cultured human CsA cells, which are historically chemo- and radio-resis.ant, may be sensitive to the ALDH inhibitor, disulfiram. While it is premature to draw broad conclusions from such a small series, the importance of ALDH activity and inhibition in the metastatic potential of primary bone sarcomas should be investigated further.
