Protection of health care workers including students from being infected when caring for high risk patients is a major cause for concern to all promoting occupational health. Safety of every employee is mandatory. Furthermore, universal guidelines for precautions must be used by all interacting with high risk patients and clients to protect themselves and prevent the spread of infection. The ai...

OBJECTIVES To assess the knowledge of universal precautions for the delivery and operating rooms by residents and students and to evaluate their use of universal precautions. STUDY DESIGN Obstetrics and gynecology (ob/gyn) residents (n = 30) and students (n = 31) from an inner-city, teaching hospital were polled by anonymous questionnaire to assess their knowledge of the appropriate barrier e...

BACKGROUND There are few data on the rate of compliance with universal precautions among pediatricians. We hypothesized that compliance in pediatrics would be poor because of the intrinsic difficulties in performing invasive procedures in small subjects. DESIGN Prospective, observational study. SETTING Tertiary care children's hospital. STUDY PARTICIPANTS A convenience sample of pediatric...

The World Health Organisation estimates there are approximately 3 million cases of needlestick injury (NSI) in healthcare workers (HCW) each year, with 90% of these occurring in developing countries 1 . Student nurses are thought to be at high risk of NSI due to poor technique, inexperience and poor use of universal precautions 2 . There has been little research into the incidence of NSI in Afr...

Universal grammar (UG) is a list of innate constraints that specify the set of grammars that can be learned by the child during primary language acquisition. UG of the human brain has been shaped by evolution. Evolution requires variation. Hence, we have to postulate and study variation of UG. We investigate evolutionary dynamics and language acquisition in the context of multiple UGs. We provi...

High-throughput crystallography has reached a level of automation where complete computer-assisted robotic crystallization pipelines are capable of cocktail preparation, crystallization plate setup, and inspection and interpretation of results. While mounting of crystal pins, data collection and structure solution are highly automated, crystal harvesting and cryocooling remain formidable challe...

BACKGROUND Universal precautions have been recommended to limit occupational exposure to the human immunodeficiency virus (HIV) and other infectious agents, but whether these recommendations have been incorporated into routine practice has not been demonstrated. METHODS Using a one-group, before-after design, we assessed the knowledge and attitudes concerning universal precautions and the lev...
