Patient experience with, and use of, an electronic monitoring system to assess vaccination responses

OBJECTIVE: To evaluate the user experience and acceptability of an electronic patient monitoring system. SETTING AND PARTICIPANTS: 822 Military and civilian personnel at a health clinic at a major US military headquarters used an Internet and telephone-based electronic monitoring system to report vaccination-site responses and symptoms after receiving the smallpox vaccination. Focus groups of vaccinees were conducted to help develop a survey about the experience that was distributed to 379 vaccinees (96% completion rate). RESULTS: Users of the electronic monitoring system reported that it was fast and easy to use and reported they would use a system like this again and recommend an electronic monitoring system to a friend or relative. Most users (84%) were comfortable with a physician tracking their vaccine reaction using their electronic reports, but only half (51%) were comfortable with eliminating the post-vaccination follow-up visit with their health-care provider based on their electronic reports. CONCLUSIONS: This electronic monitoring system was well received by vaccinees and allowed health-care providers to track the status of vaccinees. However, vaccinees were not comfortable replacing a physician visit with electronic monitoring, at least for the smallpox vaccination. A monitoring system like this may be useful in public health settings, such as mass vaccination or prophylaxis during a bioterrorism event, a pandemic influenza outbreak, or another public health emergency.     

Occupational injury and illness in the semiconductor manufacturing industry

Two thousand nine hundred and ninety-four reports of OSHA-reportable occupational injury or illness cases in 1984 from member companies of a national trade association of semiconductor manufacturing firms were analyzed. The 37 participating manufacturing facilities represented 16 companies employing over 95,000 persons, or approximately one-third of the U.S. work force for this industry in 1984. The annual incidence rate for all reportable injuries and illnesses was 2.7 per 100 full-time employees (FTE) for men and 3.7 per 100 FTE for women. Strains, sprains, or dislocations were the most frequently reported incidents (N = 956 [31.9%]), followed by cuts, lacerations, punctures, scratches, and abrasions (N = 445 [14.9%]), and chemical burns (N = 401 [13.4%]). Increased work-loss days per case were associated with manufacturing sites that did not have an employee health clinic on the premises, with custodial occupations, and with female gender.

[目的]探讨椎弓根螺钉系统联合椎间植骨融合器治疗峡部不连性腰椎滑脱症的远期疗效。[方法]自1996年10月~2002年10月本组收治峡部不连性腰椎滑脱症105例,随访资料齐全者86例。所有患者均行椎弓根螺钉系统复位滑脱,椎间植骨融合器行椎间融合固定。62例患者中1枚融合器从后斜向前呈45°植入,24例为2枚融合器从后向前垂直植入。随访测定固定节段的椎体间有无移位、滑脱有无复发,比较术前、术后2周及随访时固定椎间隙高度与近端第2椎间隙高度比值的变化。[结果]随访2~8年,平均35个月。根据NaKai评分标准,本组优56例,良13例,可17例,优良率为80.23%。Ⅰ度腰椎滑脱19例术后全部解剖复位;Ⅱ度腰椎滑脱51例中5例遗留Ⅰ度滑脱;Ⅲ度腰椎滑脱16例中4例留有Ⅰ度滑脱。末次随访时使用1枚融合器或2枚融合器所固定的椎间隙高度与近端第2椎间隙高度的比值与术后2周时的比值相比有所减低,滑脱无复发。[结论]椎弓根螺钉加椎间植骨融合器治疗腰椎滑脱症手术疗效满意,显著提高融合率,预防神经根管狭窄、神经卡压的发生,减少术后断钉和滑脱复发等问题。     

Exo-focal postischemic neuronal damage in the rat brain: alteration of [H]forskolin binding using in vitro autoradiography

We studied the alteration of intracellular signal transduction using quantitative autoradiography of the second messenger system in order to clarify the mechanisms of delayed neuronal damage in the remote areas of rat brain after transient focal ischemia. Chronological changes of [³H]forskolin binding sites were measured to demonstrate the striatal-nigral pathway after 90 min of right middle cerebral artery (MCA) occlusion and after such occlusion followed by 3 h, 6 h, 1 day, 3 days, 1 week, 2 weeks and 4 weeks of recirculation. [³H]Forskolin binding sites were found to be markedly decreased in the lateral segment of the caudate putamen supplied by the occluded MCA after 90 min of ischemia with no recirculation. On the contrary, there was no alteration on day 1, but 3 days after ischemic insult, marked reduction of [³H]forskolin binding sites was observed in the ipsilateral substantia nigra which lay outside the ischemic areas. This postischemic delayed phenomenon observed in the substantia nigra developed concurrently with ⁴⁵Ca accumulation, which was detected there in our previous study. The delayed reduction of [³H]forskolin binding sites in the substantia nigra observed in the present study indicates that striatonigral terminal degeneration at presynaptic sites is caused by precedent ischemic damage of the ipsilateral caudate putamen and that exo-focal postischemic neuronal death is caused by a transsynaptic process associated with the ischemic foci.
