Fecal microbiota transplantation to eradicate vancomycin-resistant enterococci colonization in case of an outbreak

Objective

A rapid and worrying emergence of vancomycin-resistant enterococci (VRE) gut colonization is occurring worldwide and may be responsible for outbreaks, especially in healthcare facilities. While no efficient decolonization strategies are recommended, we assessed fecal microbiota transplantation (FMT) to eradicate VRE colonization.

Multidisciplinary management of patients presenting with Lyme disease suspicion

Objective

The teaching hospital of Nancy, France, implemented a specific multidisciplinary care pathway (French acronym AMDPL) to improve the management of patients presenting with Lyme borreliosis (LB) suspicion. We aimed to assess the first year of activity of this care pathway.

负载IL-4及BMP-2的氧化石墨烯-羧甲基壳聚糖凝胶对骨免疫和骨修复的早期影响研究

目的探讨负载 IL-4 和 BMP-2 的氧化石墨烯（graphene oxide，GO）-羧甲基壳聚糖（carboxymethyl chitosan，CMC）凝胶诱导巨噬细胞 M2 型分化及对 BMSCs 成骨分化的影响。方法取 CMC、GO 制备混合溶液后，分别添加 PBS、IL-4、BMP-2 或 IL-4+BMP-2，在交联剂作用下制备单纯或负载不同因子的 GO-CMC 凝胶支架；取单纯 GO-CMC 凝胶表征观测，包括大体、扫描电镜及傅里叶变换红外吸收光谱仪（Fourier transform infrared spectroscopy，FTIR）检测，以单纯 CMC 凝胶作为对照；取负载不同因子的 GO-CMC 凝胶行体外缓释实验。取 4～5 周龄 SPF 级 SD 雌性大鼠分离培养巨噬细胞，分别与单纯以及负载不同因子的 GO-CMC 凝胶培养，24 h 后行 CD206 免疫荧光检测巨噬细胞分化情况；取第 3 代大鼠 BMSCs 分别与单纯以及负载不同因子的 GO-CMC 凝胶成骨诱导培养，10 d 后行 ALP 染色观测早期成骨，21 d 行茜素红染色观测晚期成骨。结果大体观察 GO-CMC 凝胶呈棕色、半透明状；扫描电镜观察示，GO-CMC 凝胶孔径及孔壁厚度与单纯 CMC 凝胶相似，但内壁粗糙度增加；FTIR 检测显示 CMC 发生聚合形成凝胶。体外缓释实验示 3 种负载不同因子的 GO-CMC 凝胶缓释性能相似，均呈线性缓慢释放因子。CD206 免疫荧光检测示 GO-CMC 凝胶可诱导巨噬细胞 M2 型分化，ALP 及茜素红染色示 GO-CMC 凝胶可诱导 BMSCs 成骨分化；其中负载 IL-4+BMP-2 的 GO-CMC 凝胶作用最显著（P<0.05）。 结论负载 IL-4 和 BMP-2 的 GO-CMC 凝胶可诱导巨噬细胞 M2 型分化，增强 BMSCs 成骨分化能力，为后期骨缺损修复及骨免疫调节研究提供了新的策略。     

Efectividad de un nuevo modelo de derivación telefónica compartida entre atención primaria y atención hospitalaria

Aim

The purpose of this study is to find out whether telephone referral from Primary Health Care to Internal Medicine Consult manages to reduce waiting days as compared to traditional referral. This study also aims to know how acceptable is the telephone referral to general practitioners and their patients.

Evolución e impacto bibliométrico de las becas de la Sociedad Española de Cardiología/Fundación Española del Corazón en el periodo 2007-2012

Introduction and objectivesThe Spanish Society of Cardiology/Spanish Heart Foundation (SEC/FEC) annually awards grants for cardiovascular research projects. Our objective was to analyze the trend in these investments and their resulting scientific production from 2007 to 2012.MethodsA search of the publications funded by the SEC/FEC was carried out, according to the following inclusion criteria: publication in a journal indexed in MEDLINE or EMBASE, publication date after the grant, authorship by the principal investigator of the grant, and acknowledgment of SEC/FEC funding. The impact factor and subsequent citations of the articles were analyzed (Web of Science).ResultsA total of 235 grants were awarded (39/y) with an allocation of €3 854 300 (€642 383/y), 37% of them to women. In all, 122 publications resulted from 88 research projects (37%) funded by the SEC/FEC. Up to October 2017, these publications had received 2258 citations in subsequent studies in the Web of Science, with a mean of 18.5 and a median of 8 citations/study.ConclusionsDespite the economic crisis, the mean number and size of the grants awarded by the SEC/FEC increased in the period analyzed. Grants were awarded on an equal opportunity basis to men and women. The bibliometric impact of the funded projects is acceptable, although efforts should be made to improve it.     

Quality of Pulmonary Function Tests in Participants with Down Syndrome

IntroductionPeople with Down syndrome (DS) have high respiratory morbidity, evaluating their respiratory health with standardized, objective tests is desirable. Thus, the objective of this study was to evaluate the technical quality of Pulmonary Function Tests (PFTs) to determine which ones are most suitable for this population.MethodsParticipants included children, teenagers and adults with DS, 5 years of age or older (n = 302). The technical quality of the impulse oscillometry system (IOS), forced spirometry, lung-diffusing capacity for carbon monoxide (DL_CO), and 6-min walk test (6MWT) were analyzed by age group. Capnography and pulse oximetry were included in the study. Technical quality was determined on the basis of current international PFTs standards.ResultsFifty-one percent of participants were males. A total of 184 participants (71%) who completed the IOS fulfilled the quality criteria, while 210 (70%) completed the 6MWT. Performance on forced spirometry and DL_CO was poor. All pulse oximetries and 96% percent heart rates obtained had good quality, but exhaled carbon dioxide (PetCO₂) and respiratory rate (RR) showed deficient repeatability.ConclusionsIOS appears to be the most reliable instrument for evaluating lung mechanics in individuals with DS.
