多种微量元素注射液临床应用中国专家共识（2021）

多种微量元素注射液可以提供铁、锌、铜、锰、钴、氟、碘、硒、钼、铬等多种人体微量元素，广泛应用于需要肠外营养 治疗的患者。为了进一步提高临床医师对多种微量元素注射液的认识，更好地指导其临床合理用药，特邀请全国专家组成员， 在系统性文献检索的基础上，参考欧洲临床营养与代谢学会（ESPEN）、美国肠外与肠内营养学会（ASPEN）指南，结合我国临床 实践，经多次交流讨论，达成此共识。本共识基于临床研究证据和专家经验，为多种微量元素注射液临床用于危重症、中重度 烧伤、围手术期、肿瘤、老年、透析、肠瘘及短肠综合征等提供参考。     

Determining clinically meaningful thresholds for innovative burn care products to reduce autograft: A US burn surgeon Delphi panel

Reducing the amount of donor skin needed for definitive wound closure can improve outcomes in patients with severe burns. This Delphi Consensus Panel (DCP) aimed to achieve expert consensus on the percentage reduction in donor skin for autograft that constitutes a clinically meaningful benefit. A two-round DCP of fifteen US burn surgeons was conducted via a web-based survey platform. Fourteen panelists (93.3%) completed both rounds. In Round 2, consensus, defined as ≥70% agreement, was achieved for five of the seven consensus statements. All panelists agreed that a clinically meaningful reduction in the amount of donor skin required would facilitate wound management and decrease donor site morbidity experienced by patients. Furthermore, based on three treatment scenarios, consensus was achieved for a clinically meaningful reduction in the amount of donor skin required for autograft for the adult population in deep partial-thickness and full-thickness burns. Findings from this DCP indicate that an innovative cellular and/or tissue product that would reduce the needed amount of donor skin, by the identified thresholds, has the potential to improve the outcomes for patients with severe burn injuries in a meaningful way.     

Leukocyte Esterase Versus ICM 2018 Criteria in the Diagnosis of Periprosthetic Joint Infection

BackgroundA leukocyte esterase (LE) test is inexpensive and provides real-time information about patients suspected of periprosthetic joint infections (PJIs). The 2018 International Consensus Meeting (ICM) recommends it as a diagnostic tool with a 2+ cutoff. There is still a lack of data revealing LE utility versus the ICM 2018 criteria for PJI.MethodsThis is a retrospective study of patients who underwent revision total hip and total knee arthroplasty at a single institution between March 2009 and December 2019. All patients underwent joint aspiration before the arthrotomy, and the LE strip test was performed on aspirated joint fluid. PJI was defined using the 2018 ICM criteria.ResultsAs per the 2018 ICM criteria, 78 patients were diagnosed with chronic PJI and 181 were not infected. An LE test with a cutoff of $\ge$1+ had a sensitivity of 0.744, a specificity of 0.906, a positive predictive value of 0.773, an accuracy of 0.825 (95% confidence interval 0.772-0.878), and a negative predictive value of 0.891. The positive likelihood ratio (LR+) was 7.917. Using an LE cutoff of 2 + had a sensitivity of 0.513, a specificity of 1.000, and an accuracy of 0.756 (95% confidence interval—0.812).ConclusionLE is a rapid and inexpensive test which can be performed at the bedside. Its performance is valuable as per ICM criteria. Based on the findings of this study and the given cohort, we suggest using the cutoff of LE1+ (result = negative or trace) as a point of care test to exclude infection, whereas LE at 2 + threshold has near absolute specificity for the diagnosis.

自然流产诊治中国专家共识（2020年版）

自然流产（spontaneous abortion，SA）是妇产科最常见的妊娠并发症之一。育龄期女性发生1次SA的风险为10%左右［1］。复发性流产（recurrent spontaneous abortion，RSA）的发生率为1%～5%［2］，RSA的复发风险随着流产次数的增加而上升。曾有3次以上连续自然流产史的患者再次妊娠后胚胎丢失率为40%～80%［3］。如果不及时干预，不仅会给患者及其家庭带来严重的经济负担，而且还将对患者的身心健康造成极大的影响。 浏览更多请关注本刊微信公众号及当期杂志。
