Background: While most allelic pairs of DNA replicate synchronously during the S phase of the cell cycle, some genes normally replicate asynchronously, i.e., genes on the X chromosome and imprinted genes. The replication control mechanism is unknown but was shown to be impaired in malignancies and chromosomal trisomies where replication pattern becomes asynchronous.

Objectives: To determine the level of asynchronization in replication timing of cells from patients with microdeleted genomes.

Methods: We applied monocolor fluorescent in situ hybridization with different probes on leukocytes from microdeleted genomes.

Results: All samples derived from the microdeleted genomes showed significantly higher levels of an asynchronized pattern compared to normal individuals.

Conclusions: Even a “small” genetic imbalance (microdeletion) can interfere with gene replication and cell cycle progression, as previously shown in full trisomies.
 

Background: Patient feedback is increasingly being used to assess the quality of healthcare.

Objective: To identify modifiable independent determinants of patient dissatisfaction with hospital emergency care.

Methods: The study group comprised a random sample of 3,152 of the 65,966 adult Israeli citizens discharged during November 1999 from emergency departments in 17 of the 32 acute care hospitals in Israel. A total of 2,543 (81%) responded to a telephone survey tht used a structured questionnaire. The ndependent variables included: hospital characteristics, patient demographic variables, patient perception of care, self-rated health status, problem severity, and outcome of care. The dependent variable was dissatisfaction with overall ED[1] experience on a 1–5 Likert-type scale dichotomized into not satisfied (4 and 5) and satisfied (1,2 and 3).

Results: Eleven percent of the population reported being dissatisfied with their emergency room visit. Univariate analyses revealed that dissatisfaction was significantly related to ethnic group, patient education, hospital identity and geographic location, perceived comfort of ED facilities, registration expediency, waiting times, perceived competence and attitudes of caregivers, explanations provided, self-rated health status, and resolution of the problem that led to referral to the ED. Multivariate analyses using logistic regressions indicated that the four most powerful predictors of dissatisfaction were patient perception of doctor competence and attitudes, outcomes of care, ethnicity, and self-rated health status.

Conclusions: Attempts to reduce dissatisfaction with emergency care should focus on caregiver conduct and attitudes. It may also be useful to improve caregiver communication skills, specifically with ethnic minorities and with patients who rate their health status as poor.

With chemical warfare becoming an imminent threat, medical systems need to be prepared to treat the resultant mass casualties. Medical preparedness should not be limited to the triage and logistics of mass casualties and first-line treatment, but should include knowledge and training covering the whole medical spectrum. In view of the unique characteristics of chemical warfare casualties the use of simulation-assisted medical training is highly appropriate. Our objective was to explore the potential of simulator-based teaching to train medical teams in the treatment of chemical warfare casualties. The training concept integrates several types of skill-training simulators, including high tech and low tech simulators as well as standardized simulated patients in a specialized simulated setting. The combined use of multi-simulation modalities makes this maverick program an excellent solution for the challenge of multidisciplinary training in the face of the looming chemical warfare threat.
