The New York State Department of Health (NYSDOH) collected information about hospitalized patients with Guillain-Barré syndrome (GBS) during October 2009–May 2010, statewide (excluding New York City), to examine a possible relationship with influenza A(H1N1)pdm09 vaccination. NYSDOH established a Clinical Network of neurologists and 150 hospital neurology units. Hospital discharge data from the Statewide Planning and Research Cooperative System (SPARCS) were used to evaluate completeness of reporting from the Clinical Network. A total of 140 confirmed or probable GBS cases were identified: 81 (58%) from both systems, 10 (7%) from Clinical Network only, and 49 (35%) from SPARCS-only. Capture–recapture methods estimated that 6 cases might have been missed by both systems. Clinical Network median reporting time was 12 days versus 131 days for SPARCS. In public health emergencies in New York State, a Clinical Network may provide timely data, but in our study such data were less complete than traditional hospital discharge data.  相似文献

Group relations conferences and 12-Step recovery thrive on the participants working in groups. This article is an inquiry into the integration of these traditions, in the Loyola Group Relations Conference, January 14–16, 2011. This conference recruited staff and members from the recovery community. 12-Step meetings were integrated into the conference design. The authors discuss the similarities and differences of the two models and examine the learning of conference staff and members. The authors conclude that Group Relations Conferences focusing on leadership, authority, and recovery from addiction can bring important group relations learning to the recovery community and vice versa.  相似文献

Understandings of violence, and especially sexual violence against children, must be situated within the local context. The 2009 Violence against Children Survey in Zanzibar indicated that 6% of girls and 9% of boys reported having experienced sexual violence before the age of 18 years. This paper reports on an in-depth qualitative study conducted in Zanzibar to provide further insights to these findings by examining the circumstances for sexual and other violence against children in Zanzibar. Twenty-four in-depth interviews with young people and 18 focus-group discussions with young people and adults were conducted in rural and urban Zanzibar. A further 8 interviews were conducted with parents and key stakeholders in government and NGO offices that provide services for children. The findings revealed that religious and cultural practices, which form the foundation of Swahili culture in Zanzibar, provide a moral frame for childhood development, but structural factors make children vulnerable to sexual violence. Both boys and girls are vulnerable to sexual violence in the home, neighbourhood, at school and, in particular, at madrasa or Qur’anic schools. As religion and culture are strong influences on childhood, preventing sexual violence at madrasa schools would strengthen the positive aspects of religious teachings for ensuring a safe childhood.  相似文献

Purpose: The purpose of this study was to assess the sensitivity and responsiveness of the Segmental Assessment of Trunk Control (SATCo) for evaluating trunk control in children with spinal cord injury (SCI) receiving activity-based locomotor training (AB-LT).

Methods: Prospective study of nine outcomes for consecutively enrolled children in outpatient AB-LT. To evaluate sensitivity to change, linear-mixed models were constructed and adjusted for covariates: age at and time since SCI. To evaluate responsiveness, standardized response means and 95% confidence intervals were estimated per outcome.

Results: SATCo scores increased significantly (p < 0.05) regardless of chronicity, initial score, and injury level. The SATCo was the most responsive measure and the only outcome demonstrating a large effect size after 3 months of therapy.

Conclusions: Children with SCI receiving AB-LT improved trunk control regardless of chronicity, initial impairment, or prior experience. SATCo sensitivity and responsiveness support its usefulness in measuring trunk control in children with SCI.  相似文献

In 2000, Rockland County, a small suburban county north of New York City, dedicated $1 million of its Master Settlement Agreement funds to a comprehensive tobacco control program, Put It Out Rockland. Developed and implemented by the county health department, this program used an essential public health services model and an ongoing financial investment, within the context of strong statewide tobacco control efforts, to lower adult smoking rates to 9.7% and to reduce both smoking among youths and exposure to secondhand smoke over the ensuing decade. By combining state funds and local dollars for a total of $6.75 cost per capita, this comprehensive effort yielded 11 000 fewer smokers and translated to a potential savings of more than $24 million for the county.  相似文献
