Family Caregivers' Subjective Caregiving Burden,Quality of Life,and Depressive Symptoms Are Associated With Terminally Ill Cancer Patients' Distinct Patterns of Conjoint Symptom Distress and Functional Impairment in Their Last Six Months of Life

Context

Family caregivers constitute a critical component of the end-of-life care system with considerable cost to themselves. However, the joint association of terminally ill cancer patients' symptom distress and functional impairment with caregivers' subjective caregiving burden, quality of life (QOL), and depressive symptoms remains unknown.

Evaluation of mutagenic,recombinogenic and carcinogenic potential of (+)-usnic acid in somatic cells of Drosophila melanogaster

The main of this study was to evaluate the mutagenic and carcinogenic potential of (+) – usnic acid (UA), using Somatic Mutation and Recombination Test (SMART) and the test for detecting epithelial tumor clones (wts) in Drosophila melanogaster. Larvae from 72 ± 4 h from Drosophila were fed with UA (5.0, 10.0 or 20.0 mM); urethane (10.0 mM) (positive control); and solvent (Milli-Q water, 1% Tween-80 and 3% ethanol) (negative control). ST cross produced increase in total mutant spots in the individuals treated with 5.0, 10.0 or 20.0 mM of UA. HB cross produced spot frequencies in the concentration of 5.0 mM that were higher than the frequency for the same concentration in the ST cross. In the highest concentrations the result was negative, which means that the difference observed can be attributed, in part, to the high levels of P450, suggesting that increasing the metabolic capacity maximized the toxic effect of these doses. In the evaluation of carcinogenesis using the wts test, the results obtained for the same concentrations of UA show a positive result for the presence of tumors when compared to the negative control. We conclude that UA has recombinogenic, mutagenic and carcinogenic effects on somatic cells in D. melanogaster.     

Extubación ultra fast-track vs. convencional tras cirugía cardiaca en un centro de referencia cardiovascular en Colombia. Estudio longitudinal

Introduction

The fast track / ultra-fast-track protocols are techniques used to optimise the patient care process and a quick recovery after cardiac surgery. They are one of the mainstays of efficient practice. With their use, the length of hospital and intensive care unit (ICU) stays are reduced, with a direct impact on costs and the quality of the health service.

Tanzania IR Initiative: Training the First Generation of Interventional Radiologists

Despite a population of nearly 60 million, there is currently not a single interventional radiologist in Tanzania. Based on an Interventional Radiology (IR) Readiness Assessment, the key obstacles to establishing IR in Tanzania are the lack of training opportunities and limited availability of disposable equipment. An IR training program was designed and initiated, which relies on US-based volunteer teams of IR physicians, nurses, and technologists to locally train radiology residents, nurses, and technologists. Preliminary results support this strategy for addressing the lack of training opportunities and provide a model for introducing IR to other resource-limited settings.     

《金匮要略》痈脓辨治探讨

回顾《内经》相关理论，指出痈脓病机关键在于气血凝滞、经络阻塞、脏腑失和，可分期论治。总结《金匮要略》治疗痈脓的方法，认为痈脓应尽早治疗，防邪深入；并根据证情辨证使用清热解毒，活血消散；排除脓毒，泄浊于外等治法。对现代临床仍具实用价值。      

米索前列醇联合依沙吖啶在中晚期妊娠引产中的临床应用

目的 探讨米索前列醇联合依沙吖啶在中晚期妊娠引产中的应用效果。方法 选取西安交通大学附属3201医院2012年1月—2017年12月收治的138例中晚期妊娠引产患者，按引产方式分为对照组、观察组，各69例。对照组使用乳酸依沙吖啶注射液进行引产，观察组在对照组的基础上联合使用米索前列醇进行引产。比较两组引产效果、胎儿娩出时间、阴道出血量及不良反应的发生情况。结果 观察组引产有效率是100%，显著高于对照组的91.75%（P<0.05）。观察组胎儿娩出时间<35 h的人数占比显著高于对照组（P<0.05）。观察组患者阴道出血量显著低于对照组（P<0.05），两组不良反应的发生率间差异不显著。结论 米索前列醇联合依沙吖啶在中晚期妊娠引产中的效果较好，可显著提高引产有效率、缩短胎儿娩出时间，值得临床应用。
