Immunotherapy for recurrent pregnancy loss

When immunomodulation is used on an unselected population with recurrent miscarriage (RM), there is no improvement in the live birth rate. However, when the population is selected for a poor prognosis, or immune phenomena, immunotherapy has been shown to be effective. This review discusses four immunomodulatory agents, namely, paternal leukocyte immunization, intravenous immunoglobulin (IVIg), intralipid, and filgrastim. The presence of embryonic aneuploidy may confound the results of treatment, therefore creating an impression of futility when treatment may be highly effective in saving pregnancies that can be saved. Additionally, in an unselected population with RM, there is a relatively good prognosis of 60–80% for a subsequent live birth depending on whether the definition of ≥2 or ≥3 miscarriages is used. Hence, spontaneous prognosis must be taken into account, which has not been the case in previous trials.This review discusses the possible immune-mediated mechanisms of pregnancy loss and the means whereby immunotherapy may modulate these mechanisms.     

Design of an intravenous oxygenator

The aim of this study was to design a new intravenous blood–gas exchange device and to estimate the design characteristics of the device with a dimensionless function by using a substance that can be used instead of bovine blood. In addition, the characteristics of oxygen transfer were estimated using empirical formulas and the reliability of the equations was ascertained by comparing their output with an experiment performed using bovine blood. The dimensionless function was derived using distilled water and bovine blood to estimate the oxygen transfer rate. Using the derived equations, the calculated oxygen transfer rates for bovine blood and distilled water were similar for Reynolds numbers ranging from 0.7 to 7.0. Therefore, it is possible to estimate the oxygen transfer rate in bovine blood, which is a non-Newtonian fluid, using distilled water, which is a Newtonian fluid. Moreover, it was possible to verify the related equations because the oxygen transfer rate could be estimated using the derived equations, according to the diameters of the various device modules.     

Classification of Diabetes Mellitus by Studies of C-Peptide Secretory Capacity

Residual pancreatic B-cell function was investigated in children with diabetes mellitus in whom classification of the type of disease was difficult at the first visit. Intravenous glucagon tests were performed at the first visit and subsequently, the C-peptide responses compared. Based on our data on a limited number of patients, we propose C-peptide concentrations of 3.0 to 3.5 ng/ml at the peak or at 6 min after injection of glucagon, as the critical level which distinguishes non-insulin dependent from insulin-dependent diabetes mellitus. However, the degree of obesity, clinical stage and other factors also need to be considered in the classification of diabetes mellitus.

Oral administration of methylergometrine shows a late and unpredictable effect on the non-pregnant human menstruating uterus

Objective: To study the pharmacodynamic and pharmacokinetic properties of oral and intravenous methylergometrine upon uterine motility during menstruation. Study-design: Intra-uterine pressure was measured in six volunteers with a fluid-filled sponge-tipped catheter during menstruation. Methylergometrine was given orally (0.5 mg) or intravenously (0.2 mg) in a cross-over design. Results: After intravenous administration, a fast increase of the frequency of uterine contractions and basal tone occurred with a decrease of amplitude, lasting at least 30 min. Oral administration had a late and less marked effect on uterine motility. An intravenous dose administered 24 h after an oral dose had no effect on uterine motility. Pharmacokinetic data, such as the maximum plasma concentration (C_max), the time at which C_max is reached (t_max) and the half-life of absorption (t_1/2abs) also demonstrated large individual variations after oral administration. Conclusion: Oral administration of methylergometrine had an unpredictable and late effect on uterine motility on the menstruating uterus, probably due to an unpredictable bioavailability, in contrast with the fast and predictable effect after intravenous administration.     

高龄急性脑梗死患者阿替普酶静脉溶栓有效性、安全性及预后影响因素分析

目的 探讨高龄急性脑梗死患者接受阿替普酶静脉溶栓治疗有效性、安全性和临床预后的影响
因素。
方法 前瞻性连续纳入江苏省苏北人民医院2016年9月-2018年9月收治入院进行阿替普酶静脉溶
栓治疗的急性脑梗死患者，按照年龄将患者分为年龄≥80岁组和年龄＜80岁组。比较两组患者入院
时、溶栓24 h NIHSS评分，6个月mRS评分及死亡率，观察两组溶栓相关出血转化、症状性颅内出血及
肺部感染的发生情况。应用多因素Logistic回归分析观察所有患者静脉溶栓预后的独立影响因素。
结果 最终共纳入患者119例，男性69例（58.0%），年龄范围46～94岁，平均70.12±10.55岁，入院
NIHSS评分4～38分。其中年龄≥80岁患者29例，年龄＜80岁患者90例。静脉溶栓后，两组患者溶栓
24 h NIHSS评分较入院时均明显降低（均P＜0.05），两组治疗24 h NIHSS评分比较差异无统计学意义；
两组的出血转化、症状性颅内出血、肺部感染、6个月预后良好及死亡率比较，差异均无统计学意义。
多因素Logistic回归分析显示，入院到静脉溶栓时间、入院时NIHSS评分及肺部感染是脑梗死静脉溶
栓6个月预后的独立危险因素（P＜0.05），高龄不是影响预后的因素（P＞0.05）。
结论 高龄急性脑梗死患者静脉溶栓治疗安全有效，未增加颅内出血转化风险、死亡率及不良预
后。入院到静脉溶栓时间、入院时NIHSS评分及肺部感染是急性脑梗死患者静脉溶栓6个月预后不良
的独立危险因素。
