Objective: Healthcare providers in emergency departments should wear respirators for infection protection. However, the wearer's vigorous movements during cardiopulmonary resuscitation may affect the protective performance of the respirator. Herein, we aimed to assess the effects of chest compressions (CCs) on the protective performance of respirators. Methods: This crossover study evaluated 30 healthcare providers from 1 emergency department who performed CC with real-time feedback. The first, second, and third groups started with a cup-type, fold-type, and valve-type respirator, respectively, after which the respirators were randomized for each group. The fit factors were measured using a quantitative fit testing device before and during the CC in each experiment. The protection rate was defined as the proportion of respirators achieving a fit factor ≥100. Results: The fold-type respirator had a significantly greater protection rate at baseline (100.0% ± 0.0%) compared to the cup-type (73.6% ± 39.6%, P = .003) and valve-type respirators (87.5% ± 30.3%, P = .012). During the CC, the fit factor values significantly decreased for the cup-type (44.9% ± 42.8%, P < .001) and valve-type respirators (59.5% ± 41.7%, P = .002), but not for the fold-type respirator (93.2% ± 21.7%, P = .095). Conclusions: The protective performances of respirators may be influenced by CC. Healthcare providers should identify the respirator that provides the best fit for their intended tasks.

To combat the threat of many emerging infectious diseases, DNA immunization offers a unique and powerful approach to the production of high-quality monoclonal antibodies (mAbs) against various pathogens. Compared with traditional protein-based immunization approaches, DNA immunization is efficient for testing novel immunogen designs, does not require the production or purification of proteins from a pathogen or the use of recombinant protein technology and is effective at generating mAbs against conformation-sensitive targets. Although significant progress in the use of DNA immunization to generate mAbs has been made over the last two decades, the literature does not contain an updated summary of this experience. The current review provides a comprehensive analysis of the literature, including our own work, describing the use of DNA immunization to produce highly functional mAbs, in particular, those against emerging infectious diseases. Critical factors such as immunogen design, delivery approach, immunization schedule, use of immune modulators and the role of final boost immunization are discussed in detail.

Objective: This study aimed to evaluate the prevalence and related factors of post-traumatic stress disorder (PTSD) symptoms among doctors and nurses who were exposed to H7N9 patients during the H7N9 influenza epidemic. To provide scientific basis for promoting the physical and psychological health of these staff members. Method: The 102 medical staff workers who were exposed to H7N9 patients were recruited through convenient sampling between January 2015 and May 2016. We used a self-reported questionnaire, the PTSD Checklist-Civilian Version (PCL-C), to evaluate the PTSD symptoms among doctors and nurses from an intensive care unit (n ¼ 61), a respiratory department (n ¼ 20), and an emergency department (n ¼ 21). We then analyzed the related factors. Results: Around 20.59% of the tested doctors and nurses showed PTSD symptoms. The sample had a mean PCL-C score of 30.00 ± 9.95. The differences in the scores of doctors and nurses with different genders, ages, professional titles, contact frequencies, trainings, and experiences were statistically significant (P < 0.05, P < 0.01). Moreover, t-tests and one-way analysis of variance showed that nurses received higher scores than doctors, female participants received higher scores than male participants, and the participants with low professional title and high contact frequency, aged between 20 years and 30 years, with less than five years of work experience, having not received related training and with no related experience obtained higher PCL-C scores than the others (P < 0.05, P < 0.01). Conclusion: The PTSD level of doctors and nurses after their exposure to H7N9 patients was high, which warrant further research. Health and medical institutions should pay attention to the physical and psychological health of these staff members.
