A case report of pseudoaneurysm after a core needle biopsy of breast cancer

Breast pseudoaneurysms after a core needle biopsy are a rare complication with a low incidence. However, it is important to be aware of the possibility of complications that require treatment.     

A comparison of the academic impact of plastic surgery units in the United Kingdom and Ireland using bibliometric analysis

Academic output is just one aspect of a successful career as a plastic surgeon. However, for those with a strong interest in academia, the academic output of a department will likely be a key factor when deciding how to rank jobs. The aim of this study was to quantify and rank the academic output of plastic surgery units across the UK and Ireland. The Institute for Scientific Information (ISI) Web of Science Bibliometric analysis tool was used to collate cumulative (1950–2016), 10 year (2006–2016) and 3 years (2013–2015) research output data for plastic surgery units in the UK and Ireland. Sixty-six plastic surgery units were identified. Departments were ranked for each time period according to the number of papers produced, number of citations (Nc) and h-index (a measure of the impact of scientific output). The top 3 departments for number of papers in the last 10 years were The Royal Free Hospital, London (226) Broomfield Hospital, Chelmsford (218), and Morriston Hospital and Swansea (188). The top 3 for h-number were The Royal Free Hospital (21) Wythenshawe Hospital, Manchester (18) and Morriston Hospital (17). Academic output varies across plastic surgery units in the UK and Ireland. A number of departments have consistently maintained high academic outputs across the years and will be of interest to surgeons hoping to pursue a career in academia.

甲状腺疾病患者血清 Tg-CIC 中 Tg-Ab 水平检测及相关临床研究

目的　对血清甲状腺球蛋白免疫复合物 (thyroglobulin circulating immune complex, Tg-CIC) 中抗甲状腺球蛋白抗体 (anti-thyroglobulin antibody, Tg-Ab) 含量检测，探讨 Tg-CIC 在甲状腺疾病中的临床以及流行病学意义。方法　收集甲状腺疾病患者血清标本 187 例，每例血清标本分为两组 ( 实验组和空白对照组 )，采用免疫复合物解离专利技术对甲状腺疾病患者血清标本 Tg-CIC 进行分离、解离，通过检测 Tg-CIC 解离后的 Tg-Ab 含量来间接反映甲状腺疾病患者血清中Tg-CIC 水平，按照不同的甲状腺疾病进行分组并对实验结果分析讨论。结果　不同甲状腺患者血清中 Tg-CIC 总阳性率达 92.51%，不同甲状腺疾病血清中 Tg-CIC 的阳性率差异无统计学意义 (χ?=2.917, P>0.05)。不同甲状腺疾病患者间血清游离 Tg-Ab 含量差异无统计学意义 (H=3.882, P>0.05)，不同甲状腺疾病患者间血清 CIC 中 Tg-Ab 含量差异无统计学意义(H=5.5842, P>0.05)。不同甲状腺疾病患者中，甲状腺功能亢进、甲状腺炎以及甲状腺结节患者血清游离 Tg-Ab 的含量与血清 CIC 中的 Tg-Ab 含量呈正相关 (P<0.05)，甲状腺功能减退、甲状腺肿瘤患者血清游离 Tg-Ab 的含量与血清 CIC 中的Tg-Ab 含量不相关 (P>0.05)。结论　在甲状腺疾病患者血清中，大部分可检出 Tg-CIC，与疾病类型无关。而甲状腺疾病患者中，甲状腺功能亢进、甲状腺炎以及甲状腺结节患者血清游离 Tg-Ab 含量与血清 CIC 中 Tg-Ab 含量存在相关性，为我们进一步了解 Tg-CIC 与甲状腺疾病的发生、发展的相关性研究奠定了基础，提供了新的研究视角。

Is routine extubation overnight safe in cardiac surgery patients?

Objectives

Expedient extubation after cardiac surgery has been associated with improved outcomes, leading to postoperative extubation frequently during overnight hours. However, recent evidence in a mixed medical-surgical intensive care unit population demonstrated worse outcomes with overnight extubation. This study investigated the impact of overnight extubation in a statewide, multicenter Society of Thoracic Surgeons database.

The chondrocyte channelome: A narrative review

Chondrocytes are the main cells in the extracellular matrix (ECM) of articular cartilage and possess a highly differentiated phenotype that is the hallmark of the unique physiological functions of this specialised load-bearing connective tissue. The plasma membrane of articular chondrocytes contains a rich and diverse complement of membrane proteins, known as the membranome, which defines the cell surface phenotype of the cells. The membranome is a key target of pharmacological agents and is important for chondrocyte function. It includes channels, transporters, enzymes, receptors, and anchors for intracellular, cytoskeletal and ECM proteins and other macromolecular complexes. The chondrocyte channelome is a sub-compartment of the membranome and includes a complete set of ion channels and porins expressed in these cells. Many of these are multi-functional proteins with “moonlighting” roles, serving as channels, receptors and signalling components of larger molecular assemblies. The aim of this review is to summarise our current knowledge of the fundamental aspects of the chondrocyte channelome, discuss its relevance to cartilage biology and highlight its possible role in the pathogenesis of osteoarthritis (OA). Excessive and inappropriate mechanical loads, an inflammatory micro-environment, alternative splicing of channel components or accumulation of basic calcium phosphate crystals can result in an altered chondrocyte channelome impairing its function. Alterations in Ca²⁺ signalling may lead to defective synthesis of ECM macromolecules and aggravated catabolic responses in chondrocytes, which is an important and relatively unexplored aspect of the complex and poorly understood mechanism of OA development.
