An in-house communication support system based on an information propagation model utilizing social networks

ELECTRONICS & COMMUNICATIONS IN JAPAN, Issue 12 2009
Susumu Takeuchi
Abstract Almost all companies are now utilizing computer networks to support speedier and more effective in-house information-sharing and communication. However, existing systems are designed to support communications only within the same department. Therefore, in our research, we propose an in-house communication support system which is based on the "Information Propagation Model" (IPM). The IPM is proposed to realize word-of-mouth communication in a social network, and to support information-sharing on the network. By applying the system in a real company, we found that information could be exchanged between different and unrelated departments, and such exchanges of information could help to build new relationships between the users who are apart on the social network. © 2009 Wiley Periodicals, Inc.

Does a change in obstetric management influence the incidence of traumatic birth lesions in mature, otherwise healthy newborn infants?

JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 4 2007
Willibald Zeck
Abstract Aim:, The incidence of lesions due to birth trauma can be generally regarded as a characteristic of obstetric management; since obstetric management has changed through the years, one might expect a decrease or increase of lesions due to birth trauma in mature newborn infants. Methods:, In a retrospective study, the incidence of lesions due to birth trauma was recorded in the year 2000. In 1989, an identical study had already been carried out in the same department, employing the same criteria. The new findings were compared with the historical data. Results:, In the year 1989 24.6% and in 2000 13.2% showed lesions due to obstetric trauma. The episiotomy rate and lesions due to birth trauma had significantly decreased. A decline regarding the traumas per se was noticed in caput succedaneum traumas, in hematomas due to birth trauma and in clavicle fracture. The cesarean section rate among the study group increased. The cesarean section rate among the traumatized newborns decreased. Conclusion:, Episiotomy does not prevent newborns from traumatic lesions. Gestational age and birthweight have not significantly changed throughout the years; therefore an increase in the cesarean section rate must have contributed to the decrease of birth traumas. Even during abdominal operative delivery, obstetric traumas in newborns do occur. However, an increase in cesarean sections alone can not thoroughly explain the reduction of birth lesion among newborns. Improvement in prenatal diagnostic tools and procedures, respectively, and a goal-oriented use of labor induction might also play a major role. [source]

Monitoring stress levels in postgraduate medical training

THE LARYNGOSCOPE, Issue 1 2009
Justin D. Hill MD
Abstract Objectives: The Accreditation Council for Graduate Medical Education (ACGME) mandates that residency Program Directors (PD) monitor resident well-being, including stress. Burnout, as a measure of work-related stress, is defined by a high degree of emotional exhaustion and depersonalization, and a low degree of personal accomplishment using the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). The purpose of this study is to describe the use of the MBI-HSS as a method of monitoring stress levels in an academic otolaryngology residency training program and introduce this survey as a tool for wider use in meeting ACGME requirements. Methods: The MBI-HSS was administered to residents in an academic otolaryngology residency training program on three separate occasions: at the beginning, middle, and end of different academic years. In addition, at the time of the third administration, the MBI-HSS was completed by faculty and staff in the same department. Surveys were completed and collected anonymously. Responses were scored against normative data from the MBI-HSS overall sample and the medicine subscale. Low, average, and high levels of burnout were identified for the individual categories of emotional exhaustion (EE), depersonalization (DP), and personal accomplishment (PA); average levels for each category were calculated. Results: Twenty-two residents completed the first survey, taken near the end of an academic year; 19 completed the second administration in the middle of the following academic year; and 24 completed the third survey at the beginning of the subsequent academic year. Thirteen faculty and 23 staff also completed the third survey. We found that three, one, and one residents reported high levels of burnout on the first, second, and third surveys, respectively. These figures compare to one faculty member and no staff members in the same department reporting high levels of burnout. Conclusions: The MBI-HSS is an established and validated tool for identifying burnout in resident physicians. Residency PDs may find the MBI-HSS useful as an aid in monitoring resident well-being and stress. In our own department, we found levels of burnout comparable to those previously reported for residents and faculty in this specialty. Laryngoscope, 119:75,78, 2009 [source]

Autologous Fixed Tumor Vaccine: A Formulation with Cytokine-microparticles for Protective Immunity against Recurrence of Human Hepatocellular Carcinoma

CANCER SCIENCE, Issue 4 2002
Bao Gang Peng
We developed a tumor vaccine consisting of fixed hepatocellular carcinoma (HCC) cells/tissue fragments, biodegradable microparticles encapsulating granulocyte-macrophage-colony stimulating factor and interleukin-2, and an adjuvant. The vaccine protected 33% of syngeneic mice from HCC cell challenge. The vaccine containing human autologous HCC fragments showed essentially no adverse effect in a phase I/IIa clinical trial and 8/12 patients developed a delayed-type hyper-sensitivity (DTH) response against the fragments. Although 2 of 4 DTH-response-negative patients had recurrence after curative resection, the DTH-response-positive patients had no recurrence. The time before the first recurrence in the vaccinated patients was significantly longer than that in 24 historical control patients operated in the same department (P<0.05). This formulation is a promising candidate to prevent recurrence of human HCC. [source]
