The Strongest Correlates of PTSD for Firefighters: Number,Recency, Frequency,or Perceived Threat of Traumatic Events? 下载免费PDF全文
Ricardo J. Pinto Sandra P. Henriques Inês Jongenelen Cláudia Carvalho Ângela C. Maia 《Journal of traumatic stress》2015,28(5):434-440
Firefighters experience a wide range of traumatic events while on duty and are at risk to develop psychopathology and posttraumatic stress disorder (PTSD). According to cognitive models, the person's interpretation of the traumatic event is responsible for the development of PTSD rather than the traumatic event itself. This cross‐sectional study aimed to explore the contribution of perceived threat to explain PTSD symptoms in Portuguese firefighters, after adjusting for potential confounding factors. A sample of 397 firefighters completed self‐report measures of exposure to traumatic events, psychopathology, and PTSD. Perceived threat explained unique variance in PTSD symptoms, R2 = .40, ΔR2 = .02, F(10, 367) = 24.55, p < .001, Cohen's f2 =.03, after adjusting for psychopathology, number, recency, and frequency of the events, and other potential confounding variables. The association between psychopathology and PTSD was also moderated by perceived threat, R2 = .43, ΔR2 = .03, F(11, 366) = 25.33, p < .001, Cohen's f2 =.05. Firefighters may benefit from interventions that focus on perceived threat to prevent PTSD symptoms. 相似文献

[Purpose] The aim of the present study was to assess the knowledge of the spine and
posture among adolescent female students and to determine if they had access to postural
education in or outside school. [Subjects and Methods] This was an epidemiological survey
of a representative sample of 495 female students aged 14 to 18 years attending a regular
secondary school in São Leopoldo, RS, Brazil. Data were collected through a questionnaire.
[Results] The results showed that 16.8% of teens did not know what a spine was, 8.3% had
no knowledge of posture, and 61% reported receiving no posture education. Posture
awareness was associated only with posture while using a computer, while having postural
education class was not associated with any postural behavior. [Conclusion] The results
showed that, although most students are familiar with the spine and posture, a sizable
group is not, and over half had no postural education. These findings suggest that
inclusion of postural education programs in schools should be encouraged in order to
promote health and prevent diseases related to the spine.Key words: Posture, Adolescent health, School health 相似文献

Stem cell bioengineering strategies to widen the therapeutic applications of haematopoietic stem/progenitor cells from umbilical cord blood 下载免费PDF全文
Pedro Z. Andrade Francisco dos Santos Joaquim M. S. Cabral Cláudia L. da Silva 《Journal of tissue engineering and regenerative medicine》2015,9(9):988-1003
Umbilical cord blood (UCB) transplantation has observed a significant increase in recent years, due to the unique features of UCB haematopoietic stem/progenitor cells (HSCs) for the treatment of blood‐related disorders. However, the low cell numbers available per UCB unit significantly impairs the widespread use of this source for transplantation of adult patients, resulting in graft failure, delayed engraftment and delayed immune reconstitution. In order to overcome this issue, distinct approaches are now being considered in clinical trials, such as double‐UCB transplantation, intrabone injection or ex vivo expansion. In this article the authors review the current state of the art, future trends and challenges on the ex vivo expansion of UCB HSCs, focusing on culture parameters affecting the yield and quality of the expanded HSC grafts: novel HSC selection schemes prior to cell culture, cytokine/growth factor cocktails, the impact of biochemical factors (e.g. O2) or the addition of supportive cells, e.g. mesenchymal stem/stromal cell (MSC)‐based feeder layers) were addressed. Importantly, a critical challenge in cellular therapy is still the scalability, reproducibility and control of the expansion process, in order to meet the clinical requirements for therapeutic applications. Efficient design of bioreactor systems and operation modes are now the focus of many bioengineers, integrating the increasing 'know‐how' on HSC biology and physiology, while complying with the GMP standards for the production of cellular products, i.e. through the use of commercially available, highly controlled, disposable technologies.
