    目的:探讨全髋关节置换术(THA)后手术入路和术后预防对异位骨化(HO)发生的影响。
    方法:对2009年1月至2016年4月接受THA的312例患者进行回顾性分析。患者按手术入路(直接外侧或后外侧)进行分类,假体类型,和术后预防(依托考昔60mg,每日2周)。两名整形外科医生以连续间隔独立评估X光片,HO按照Brooker分类进行分级。进行了双变量分析和回归建模,以评估不同变量的关联和混杂效应。结果:双变量分析确定了与高HO发生率相关的因素:缺乏预防,年龄较大,更长的症状演变,和较低的术前体力活动。回归模型显示了直接-横向方法之间的相关性,术后预防,症状演变,HO发病率较高。
    结论:手术前症状演变时间较长且未进行术后预防的患者发生HO的风险较高。虽然直接横向进近显示出更高的HO率,差异微不足道。THA后,每天60mg的依托考昔预防两周的方案可有效减少HO的形成。药物预防应根据具体情况进行评估,考虑患者特征和危险因素。
    OBJECTIVE: To investigate the impact of surgical approach and post-operative prophylaxis on heterotopic ossification (HO) development after total hip arthroplasty (THA).
    METHODS: A retrospective analysis of 312 patients who underwent THA between January 2009 and April 2016. Patients were categorized by surgical approach (direct lateral or posterolateral), prosthesis type, and post-operative prophylaxis (Etoricoxib 60 mg daily for two weeks). Two orthopaedic surgeons independently assessed radiographs at serial intervals, and HO was graded as per Brooker classification. Bivariate analysis and regression modelling were performed to assess the associations and confounding effects of different variables, RESULTS: Bivariate analysis identified factors correlated with higher HO incidence: absence of prophylaxis, older age, longer symptom evolution, and lower pre-surgery physical activity. Regression modelling showed a correlation between the direct-lateral approach, post-operative prophylaxis, symptom evolution, and higher HO incidence.
    CONCLUSIONS: Patients with longer symptom evolution before surgery and without post-operative prophylaxis are at higher risk of developing HO. While the direct lateral approach showed higher HO rates, the difference was insignificant. A two-week prophylactic regimen of Etoricoxib 60 mg daily after THA effectively reduced HO formation. Pharmacological prophylaxis should be evaluated case-by-case, considering patient characteristics and risk factors.

    肠癌是一个重要的全球健康问题,位居全球第三的癌症。腹腔镜切除已成为可切除的结直肠癌的标准治疗方式。本研究旨在比较腹腔镜结直肠癌切除术中内侧至外侧(ML)与外侧至内侧(LM)方法的临床和肿瘤结果。
    2015年至2019年在英国地区综合医院进行了一项回顾性队列研究,包括402名符合特定标准的患者。人口统计,临床,Operative,术后,并收集肿瘤数据。参与者被分为LM和ML组。主要结果是30天并发症,次要结果包括手术持续时间,逗留时间,淋巴结收获,和3年生存率。
    共纳入402例患者(55.7%男性):外侧动员(LM)组102例(51.6%女性),内侧动员(ML)组280例(58.9%男性)。右半结肠切除术(n=157,39.1%)和前切除术(n=150,37.3%)是执行最多的手术。LM组右半结肠切除术的手术时间较短(中位数165vs.225分钟,P<0.001)和前切除术(中位数230vs.300分钟,P<0.001)。两组在伤口感染方面差异无统计学意义(P=0.443)。吻合口漏(P=0.981),术后肠梗阻(P=0.596),住院时间(P=0.446),淋巴结产量(P=0.848)或3年总生存率(Log-rank0.759)。
    该研究为ML与LM方法的有限证据做出了贡献。在这项研究中,LM组的手术时间较短,与一些文学相反。术后结果具有可比性,LM组术后肠梗阻无显著增加。该研究强调了两种方法的安全性和可行性。
    UNASSIGNED: Bowel cancer is a significant global health concern, ranking as the third most prevalent cancer worldwide. Laparoscopic resections have become a standard treatment modality for resectable colorectal cancer. This study aimed to compare the clinical and oncological outcomes of medial to lateral (ML) vs lateral to medial (LM) approaches in laparoscopic colorectal cancer resections.
    UNASSIGNED: A retrospective cohort study was conducted at a UK district general hospital from 2015 to 2019, including 402 patients meeting specific criteria. Demographic, clinical, operative, postoperative, and oncological data were collected. Participants were categorised into LM and ML groups. The primary outcome was 30-day complications, and secondary outcomes included operative duration, length of stay, lymph node harvest, and 3-year survival.
    UNASSIGNED: A total of 402 patients (55.7% males) were included: 102 (51.6% females) in the lateral mobilisation (LM) group and 280 (58.9% males) in the medial mobilisation (ML) group. Right hemicolectomy (n=157, 39.1%) and anterior resection (n=150, 37.3%) were the most performed procedures. The LM group had a shorter operative time for right hemicolectomy (median 165 vs. 225 min, P<0.001) and anterior resection (median 230 vs. 300 min, P<0.001). There was no significant difference between the two groups in terms of wound infection (P=0.443), anastomotic leak (P=0.981), postoperative ileus (P=0.596), length of stay (P=0.446), lymph node yield (P=0.848) or 3-year overall survival rate (Log-rank 0.759).
    UNASSIGNED: The study contributes to the limited evidence on ML vs LM approaches. A shorter operative time in the LM group was noted in this study, contrary to some literature. Postoperative outcomes were comparable, with a non-significant increase in postoperative ileus in the LM group. The study emphasises the safety and feasibility of both approaches.

    Assessing the economic value of livestock such as cattle, goats, sheep, pigs, chickens and fish can offer information about their financial performance and economic importance at farm, national and global scale. Such information is needed for decision-making surrounding livestock finance, investment and strategic development. The aim of this study was to provide an overview of the key livestock valuation methods and associated data requirements. The study was conducted using a literature review. Five key livestock valuation methods were identified and described: historical costs, net current market value, replacement costs, net present value and cost of production. The findings of this study may be of interest to livestock scientists, veterinarians, policy-makers and other stakeholders who aim to assess the economic value of livestock herds. The Global Burden of Animal Diseases programme relied on the outcomes of this study to identify methods for the estimation of the economic value of livestock at the global scale and for its Ethiopia and Indonesia case studies.
    L\'estimation de la valeur économique des animaux d\'élevage (bovins, caprins, ovins, porcins, poulets et poissons d\'élevage) peut apporter un éclairage sur leurs performances financières et leur intérêt économique à l\'échelle d\'une exploitation, d\'un pays ou du monde. Ces informations sont indispensables pour étayer les décisions de financement, d\'investissement et de développement stratégique des élevages. L\'étude présentée par l\'autrice vise à donner une vue d\'ensemble des principales méthodes d\'estimation de la valeur des animaux d\'élevage et des exigences qui leur sont associées en termes de données. L\'étude repose sur un examen de la littérature sur le sujet. Cinq méthodes principales d\'estimation de la valeur des animaux d\'élevage y sont répertoriées et décrites : coûts historiques, valeur marchande courante nette, coûts de remplacement, valeur actuelle nette et coûts de production. Les résultats de cette étude pourraient intéresser les spécialistes de l\'élevage, les vétérinaires, les décideurs politiques et d\'autres parties prenantes qui cherchent à évaluer la valeur économique des cheptels. Le programme \" Impact mondial des maladies animales \" s\'est appuyé sur les résultats de cette étude pour retenir les méthodes d\'estimation de la valeur économique des animaux d\'élevage appliquées à l\'échelle mondiale ainsi que dans les études de cas conduites en Ethiopie et en Indonésie.
    Evaluar el valor económico del ganado, como vacas, cabras, ovejas, cerdos, pollos y peces, puede ofrecer información sobre su desempeño financiero y su importancia económica tanto a nivel de la explotación como a escala nacional y mundial. Esta información es necesaria para la toma de decisiones en materia de financiación, inversión y desarrollo estratégico de la ganadería. El objetivo de este estudio era ofrecer una visión general de los principales métodos de valoración del ganado y de las necesidades de datos conexas. Para ello, se llevó a cabo una revisión bibliográfica y se distinguieron y describieron cinco métodos fundamentales de valoración de la ganadería: costes históricos, valor actual de mercado neto, costes de reposición, valor actual neto y costes de producción. Las conclusiones de este estudio pueden ser de interés para científicos que trabajan en el ámbito de la ganadería, veterinarios, responsables de la toma de decisiones y otras partes interesadas en la evaluación del valor económico del ganado. El programa sobre el Impacto Global de las Enfermedades Animales se basó en los resultados de este estudio para definir métodos de estimación del valor económico del ganado a escala mundial y para sus estudios de caso de Etiopía e Indonesia.

    跛行是儿童常见的抱怨。尽管如此,由于病因学列表的扩大,这对于治疗医生来说仍然是一个诊断挑战.它源于一系列疾病,从不同发育阶段步态的生理变化到全身原因,如炎性疾病或肌肉骨骼感染。在极少数情况下,非肌肉骨骼原因可能导致跛行。诊断挑战在年龄较小的儿童中增加,其中可能无法进行详细的体格检查以帮助确定病理的确切来源。在步态周期发育良好的老年患者中,物理评估可能更容易。出现跛行的儿童的临床评估包括步态分析,这对于指导诊断实验室测试和成像研究的适当要求至关重要。在本文中,我们为普通儿科和儿科风湿病学的受训者提供了实用的指导,旨在确定跛行的常见原因,并描述正常和异常的步态周期。我们还讨论了评估这些儿童的其他诊断考虑因素。
    Limping is a common presenting complaint in children. Despite this, it remains to be a diagnostic challenge for treating physicians due to an expanded list of etiologies. It arises from a spectrum of disorders, ranging from physiological variations of gait at different stages of development to systemic causes, such as inflammatory diseases or musculoskeletal infections. On rare occasions, non-musculoskeletal causes could result in limping. The diagnostic challenge increases in younger age children where a detailed physical examination that helps identify the exact source of pathology may not be possible. In older patients who have a well-developed gait cycle, the physical assessment might be easier. Clinical assessment in a child presenting with a limp includes gait analysis, which is essential to guide the appropriate request of diagnostic laboratory tests and imaging studies. In this paper, we provide a practical guide for a trainee in General Pediatric and Pediatric Rheumatology on an approach to a limping child, aiming to identify the common causes of limping and to describe normal and abnormal gait cycles. We also discuss other diagnostic considerations in the assessment of these children.

    儿童和青少年的髋部化脓性关节炎是需要及时诊断和干预的常见病。手术冲洗和清创术通常通过前入路进行,因为担心内侧旋股动脉损伤会导致无血管坏死。虽然有多项研究调查了前内侧入路减少髋关节发育脱位的后遗症,没有人将这些方法与小儿化脓性髋关节进行比较。我们假设,当比较小儿患者的内侧和前入路与化脓性髋部时,无血管坏死的发生率没有显着差异。
    在18年的时间内,对通过内侧或前入路在单个机构进行冲洗和清创治疗的小儿化脓性髋部进行了回顾性回顾。主要结果指标是缺血性坏死的发展。
    164例患者中有13例(7.9%)出现了缺血性坏死。101例前入路患者中有9例出现血管坏死,63例内侧入路患者中有4例出现血管坏死(p=0.76)。发生缺血性坏死的患者的平均年龄为10.0岁,而未发生缺血性坏死的患者为6.8岁(p=0.01)。缺血性坏死患者的平均随访时间为3.3年,而未发生缺血性坏死的患者为1.5年(p=0.01)。
    与前路相比,小儿化脓性髋关节的内侧入路不会增加缺血性坏死的发生率。
    回顾性比较研究,三级。
    UNASSIGNED: Septic arthritis of the hip in children and adolescents is a common condition requiring timely diagnosis and intervention. Surgical irrigation and debridement is typically performed through the anterior approach because of concerns about injury to the medial femoral circumflex artery leading to avascular necrosis. While there are multiple studies investigating the sequelae of anterior and medial approaches for reduction of developmental dislocation of the hip, none have compared these approaches for the pediatric septic hip. We hypothesize that there will be no significant difference in the rate of avascular necrosis when comparing the medial and anterior approaches to the septic hip in pediatric patients.
    UNASSIGNED: A retrospective review was performed of pediatric septic hips treated with irrigation and debridement through either a medial or anterior approach at a single institution over an 18-year period of time. The primary outcome measure was the development of avascular necrosis.
    UNASSIGNED: Thirteen of 164 patients (7.9%) developed avascular necrosis. Avascular necrosis was noted in 9 of 101 patients who had anterior approach and 4 of 63 patients who underwent medial approach (p = 0.76). The average age for patients developing avascular necrosis was 10.0 years old versus 6.8 years old in patients who did not develop avascular necrosis (p = 0.01). The average follow-up was 3.3 years in patients with avascular necrosis versus 1.5 years for patients who did not develop avascular necrosis (p = 0.01).
    UNASSIGNED: Medial approach to the pediatric septic hip does not increase the rate of avascular necrosis compared to the anterior approach.
    UNASSIGNED: Retrospective comparison study, Level III.

    几个有影响力的理论提出了互感信号,从身体发送到大脑,有助于协调复杂行为的神经过程。使用不穿过血脑屏障的药物,我们改变了恒河猴的相互感受状态,并评估了它们对决策的影响。我们用格隆溴铵,一种非特异性毒蕈碱(副交感神经)拮抗剂,和异丙肾上腺素,β-1/2(交感神经)激动剂,以增加心率为索引的交感神经主导的生理状态。恒河猴接受了避免接近冲突任务的两种变体的训练,他们在忍受轻度厌恶的刺激之间做出选择,以换取稳定的回报,或者取消厌恶刺激,放弃奖励。中断厌恶刺激的延迟和奖励被用作推动猴子决策的成本效益估计的衡量标准。两种药物都改变了回避方法的决定,大大减少了中断厌恶刺激的延迟。为了确定这种自主状态是否降低了对厌恶刺激的耐受性或降低了奖励的主观价值,我们测试了格隆溴铵对食物偏好任务的影响。食物偏好没有改变,这表明交感神经支配状态选择性地降低了对厌恶刺激的耐受性,而不会改变寻求奖励的行为。由于这些药物对大脑生理没有直接影响,互感传入是决策偏向回避的最可能机制。
    有影响力的理论提出,身体的器官向大脑发送信息,这些信号有助于更高的认知功能,包括情绪。同时,大脑根据有机体的行为议程调整身体生理。对这些想法的经验支持,然而,由于难以分离大脑回路和身体生理学对认知过程的贡献,因此受到限制。在这里,我们使用不穿过血脑屏障的药物选择性地操纵身体的自主神经状态,而猕猴执行复杂的决策任务。引起持续外周交感神经活动的药物显着改变了决策。这些发现表明,提升,交互感受信号在塑造行为中起着至关重要的作用。
    Several influential theories have proposed that interoceptive signals, sent from the body to the brain, contribute to neural processes that coordinate complex behaviors. Using pharmacological agents that do not cross the blood-brain barrier, we altered interoceptive states and evaluated their effect on decision-making in rhesus monkeys. We used glycopyrrolate, a non-specific muscarinic (parasympathetic) antagonist, and isoproterenol, a beta-1/2 (sympathetic) agonist, to create a sympathetic-dominated physiological state indexed by increased heart rate. Rhesus monkeys were trained on two variants of an approach-avoidance conflict task, where they chose between enduring mildly aversive stimuli in exchange for a steady flow of rewards, or cancelling the aversive stimuli, forgoing the rewards. The delay to interrupt the aversive stimuli and the reward were used as a measure of the cost-benefit estimation that drove the monkeys\' decisions. Both drugs altered approach-avoidance decisions, substantially reducing the delay to interrupt the aversive stimuli. To determine whether this autonomic state lowered tolerance to aversive stimuli or reduced the subjective value of the reward, we tested the effects of glycopyrrolate on a food preference task. Food preference was unaltered, suggesting that the sympathetic dominated state selectively reduces tolerance for aversive stimuli without altering reward-seeking behaviors. As these drugs have no direct effect on brain physiology, interoceptive afferents are the most likely mechanism by which decision making was biased toward avoidance.

    三角脑膜瘤是罕见的脑室内肿瘤,具有手术挑战性。对于这些病变的最佳手术方法尚无共识,尽管最常采用的是经脑和经顶入路。我们旨在研究治疗三角脑膜瘤的方法相关的发病率和手术细微差别。这项回顾性研究总结了来自64例手术超过15年的三角脑膜瘤的数据。临床放射表现的细节,手术入路和术中印象,记录各种术后缺陷的病理和发生率.在我们的研究中,三角脑膜瘤最常见的是头痛和视力下降。肿瘤的中位体积为63.6cc。每个31个脑膜瘤(48.4%)为WHO1级和WHO2级,而2个为WHO3级。最常见的方法是经经经经(38例患者,59.4%),其次是经顶(22例,34.4%)。在所有患者的ICP升高和精神状态改变的手术后,而对侧肢体无力缓解了80%,失语症占60%,70%的癫痫发作,视力下降46.2%。18例(28.13%)患者术后出现短暂性神经功能缺损,一名患者(1.5%)发展为永久性发病率。IVMs的手术导致神经状态的快速改善,尽管手术前视力低下的患者的视力效果较差,投诉和视神经萎缩的持续时间较长。一些患者的新的术后缺陷在随访中趋于改善。可以采用经茎和经顶方法,基于多种因素,如肿瘤扩展,颞角的定位,病变大小,其安全性无显着差异。
    Trigonal meningiomas are rare intraventricular tumours that present a surgical challenge. There is no consensus on the optimal surgical approach to these lesions, though the transtemporal and transparietal approaches are most frequently employed. We aimed to examine the approach-related morbidity and surgical nuances in treating trigonal meningiomas. This retrospective review assimilated data from 64 trigonal meningiomas operated over 15 years. Details of clinicoradiological presentation, surgical approach and intraoperative impression, pathology and incidence of various postoperative deficits were recorded. In our study, Trigonal meningiomas most frequently presented with headache and visual deterioration. The median volume of tumours was 63.6cc. Thirty-one meningiomas each (48.4%) were WHO Grade 1 and WHO Grade 2, while 2 were WHO Grade 3. The most frequent approach employed was transtemporal (38 patients, 59.4%), followed by transparietal (22 patients, 34.4%). After surgery features of raised ICP and altered mental status resolved in all patients, while contralateral limb weakness resolved in 80%, aphasia in 60%, seizures in 70%, and vision loss in 46.2%. Eighteen patients (28.13%) developed transient postoperative neurological deficits, with one patient (1.5%) developing permanent morbidity. Surgery for IVMs results in rapid improvement of neurological status, though visual outcomes are poorer in patients with low vision prior to surgery, longer duration of complaints and optic atrophy. The new postoperative deficits in some patients tend to improve on follow up. Transtemporal and transparietal approaches may be employed, based on multiple factors like tumour extension, loculation of temporal horn, size of lesion with no significant difference in their safety profile.

    UNASSIGNED: We improved the technique notes on the management of superior sagittal or transverse sinus in three FM patients with signs of increased intracranial pressure or chronic headache.
    UNASSIGNED: All patients underwent surgeries in the prone position, and occipital/sup-occipital/sub-occipital craniotomy was performed. In one patient, the skull was removed traditionally with exposure of the confluence of sinuses, superior sagittal, and transverse sinus, while the longitudinal skull bridge was left to suspend the dura for protecting the superior sagittal sinus in one patient, and the transverse skull bridge was left to suspend the dura for protecting the transverse sinus in one patient. The dura was opened infratentorially or supratentorially to spare the sinus and then the \"skull bridge\" was suspended. The tumor was then removed completely without brain swelling or significant venous bleeding. Complete tumor resection was confirmed by early postoperative imaging, and all patients recovered well without postoperative morbidity.
    UNASSIGNED: The authors recommend the \"skull bridge\" to suspend the dura for optimal control of the venous sinuses during FM surgery (less venous bleeding).

    来自横截面和线索反应性研究的越来越多的证据支持将渴望的矛盾模型(AMC)从物质使用文献应用于食物渴望。这项现有工作的重点一直放在食物渴望(接近和回避)和无序饮食行为的两个维度之间的关联上。本研究通过调查方法和避免食物渴望概况及其与1)饮食行为紊乱和2)瘦弱/限制和饮食期望的关联来扩展现有的有效性数据-AMC明确描述了饮食紊乱的风险因素。预计食物渴望概况将与AMC定义的概况平行(即,以方法为导向,面向回避,矛盾的,冷漠),并且由高度回避食物渴望定义的特征在代偿行为中会更高,限制行为,和瘦弱/限制预期,而那些由高接近食物渴望定义的人在暴饮暴食和饮食期望中会更高。407名本科生的样本(54%为女性,47%的非西班牙裔白人;法师=21岁)报告了人口统计数据,食物渴望无序的饮食行为,通过匿名在线调查,瘦身/限制和饮食期望。潜在轮廓分析用于检验假设。假设得到了部分支持。确定了四个配置文件,但是在每个配置文件中观察到相似的接近和避免食物渴望水平,随着四种轮廓的渴望强度增加。在整个配置文件中,对无序饮食行为和期望的认可也增加了强度。研究结果表明一种添加剂,而不是互动,食物渴望的影响。
    Accumulating evidence from both cross-sectional and cue-reactivity studies supports the application of the Ambivalence Model of Craving (AMC) from the substance use literature to food craving. The focus of this extant work has been on the association between the two dimensions of food craving (approach and avoidance) and disordered eating behaviors. The present study extended existing validity data by investigating approach and avoidance food craving profiles and their associations with 1) disordered eating behaviors and 2) thinness/restriction and eating expectancies - a risk factor for disordered eating that is explicitly described by the AMC. It was anticipated that food craving profiles would parallel those defined by the AMC (i.e., approach oriented, avoidance oriented, ambivalent, indifferent) and that profiles defined by high avoidance food craving would be higher in compensatory behaviors, restricting behaviors, and thinness/restriction expectancies, while those defined by high approach food craving would be higher in binge eating and eating expectancies. A sample of 407 undergraduate students (54% female, 47% non-Hispanic White; Mage = 21 years) reported demographics, food craving disordered eating behaviors, and thinness/restriction and eating expectancies via an anonymous online survey. Latent profile analysis was used to test hypotheses. Hypotheses were partially supported. Four profiles were identified, but similar levels of approach and avoidance food craving were observed in each profile, with the intensity of the cravings increasing across the four profiles. Endorsement of disordered eating behaviors and expectancies also increased in intensity across the profiles. Findings suggest an additive, rather than interactive, effect of food craving.
