Anesthesia practices in the united states common to in vitro fertilization (IVF) centers

Purpose: Our purpose was to characterize and describe anesthesia practice in programs performing IVF in the United States. Methods: We used a telephone survey requiring respondents to be either the program director, a physician, or a nurse familiar with the practice. Two hundred seven (78%) Society of Assisted Reproductive Technology (SART) registered programs agreed to participate. Programs were divided by geographic region and type of practice (academic versus private). Results: Ninety-one private (68%) and 41 academic (56%) programs used personnel provided by the Department of Anesthesiology. Conscious sedation was performed most commonly (95%). The remaining 5% used primarily either general, regional, or local anesthesia. Typical recovery times were 90 to 120 min. Average costs of anesthetic administration were $300–$400 and were similar among groups except for the Eastern academic programs, with a higher mean cost of $543. Programs using personnel from anesthesiology reported higher costs compared to programs utilizing their own staff ($391±15 vs $157±11; P<0.05). Complications were infrequent (<10%); no hospitalizations or serious life-threatening incidents were reported. Conclusions: A large number of programs safely used their own trained personnel to deliver anesthesia, and realized a significant reduction in cost.

The multifunctional therapy room of the future: image guidance, interdisciplinarity, integration and impact on patient pathways

With few exceptions the interventional rooms of the present are either imaging suites or sterile operating rooms. Their users are restricted to either percutaneous procedures or to two-staged image-guided surgery without intra-operative imaging control. Since interventional therapy of the future will be minimally invasive and since minimally invasive therapy is essentially image-guided therapy, a new physical place for these activities has to be devised: the multifunctional therapy room of the future integrates sophisticated imaging and image guidance modalities together with advanced surgical and life-support equipment in a sterile environment [1, 2, 3]. Even given a high degree of integration, this will be a complex and costly piece of medical technology. These two factors – complexity and cost – require interdisciplinary technological and medical collaboration to bring it into existence, distribute its cost and maximize usage and medical benefit. Yet another dimension of multifunctionality will be introduced and a significant impact on the care of vitally threatened patients will be exerted by using this room not only for elective image-guided therapy but also for emergent one-stop diagnosis and treatment. Motivation, technology, implementation strategies and funding of this image-guided, integrated and interdisciplinary therapy room, as well as a comprehensive approach combining emergency care and elective computer-assisted therapy (CAT), are discussed in this paper.

Educating early childhood teachers for the global world

Teachers for the twenty-first century for the global world need to be proficient in technology and skilled as reflective practitioners. They need to be able to reflect on diversity in myriad ways: learning styles, special needs, cultural differences, racial differences, developmentally appropriate differences, teaching styles and personality differences of children, teachers, parents, community members and administrators. The paradigni shift of the twenty-first century is that teachers need to be team players who are skilled at operating in a variety of collaborative partnerships.

The Early Childhood Program Faculty, at NEIU, with the help of a Teacher Quality Education grant, developed with six universities in Illinois called Illinois Professionals Learning Partnerships (IPLP), set out to adapt the NEIU/ECED program for the twenty-first century in a global world by focusing on four goals: (1) increasing technology and writing skills across the curriculum, (2) developing reflective skills and understanding of diversity (special needs, multicultural/international cultures), (3) developing student experience working in collaborative partnerships and (4) increasing clinical experiences.

The IPLP grant enabled the ECED program to: (1) spend intensive time on changing the curriculum in two retreats a year, (2) develop a faculty cohort including tenure track faculty, visiting lecturers and adjuncts, (3) develop a combined program of research and program development, (4) recruit and hire three new tenure track international faculty, (5) develop professional development schools and intensive field experiences, (6) combine resources for many grants, (7) develop short-term international experiences and faculty exchange programs and (8) increase technology skills of students and faculty through action laboratories on using video technology, digital cameras, reflective email discussions and videography.

食管鳞癌中pRb2/p130、Cdk4和c-myc的表达及意义

目的:探讨pRb2/p130、Cdk4和c-myc在食管鳞癌中的表达及意义。方法:应用Immuno-Bridge+免疫组化法检测了pRb2/p130、Cdk4和c-myc在60例食管鳞癌中的表达水平,用χ2检验分析它们与临床病理指标及它们三者之间相互关系,用Kaplan-Meier方法绘制生存曲线并进行生存分析,Cox比例风险模型作预后分析。结果:食管鳞癌中pRb2/p130的低表达与癌组织分化程度、TNM分期、淋巴结转移、浸润深度有关;Cdk4的高表达与癌组织的分化程度、TNM分期、淋巴结转移相关;c-myc的高表达与淋巴结转移相关;Kaplan-Meier生存分析表明pRb2/p130高表达组(+)的各期的生存率均高于低表达组(-);Cox比例风险模型分析显示pRb2/p130、淋巴结转移、癌组织分化程度是食管鳞癌的独立预后指标。结论:食管鳞癌中存在pRb2/p130的低表达以及Cdk4和c-myc的高表达,促进了细胞的生长和肿瘤的发展,是食管癌发生发展中的重要事件。
