statement of the problem: exposure to patients’ blood and body fluids would prone the dental students to the risk of blood borne infections. several studies have shown a high prevalence of these exposures in dental settings particularly in developing countries. however, few studies have evaluated the epidemiology of these exposures in dental students in iran. purpose: to assess the epidemiology...

Spinal cord injury (SCI) results in a loss of motor and sensory function and is consequent with reductions in locomotion, leading to a relatively sedentary lifestyle which predisposes individuals to premature morbidity and mortality. Many exercise modalities have been employed to improve physical function and health status in SCI, yet they are typically expensive, require many trained clinician...

Underground water in many regions of the world is contaminated with high concentrations of arsenic and the resulting toxicity has created a major environmental and public health problem in the affected regions. Chronic arsenic exposure can cause many diseases, including various physical and psychological harms. Although the physical problems caused by arsenic toxicity are well reported in liter...

Prenatal development is recognized as a critical period in the etiology of obesity and cardiometabolic disease. Potential strategies to reduce maternal obesity-induced risk later in life have been largely overlooked. In this paper, we first propose a conceptual framework for the role of public health and preventive medicine in mitigating the effects of fetal programming. Second, we review a sma...

This paper investigates the reality of shared manipulation of objects between users in distributed walkin displays and presents solutions to address the effects of constraints of network technology. Various forms of shared interaction are examined through a single structured task of building a Gazebo. Communication of tracking data can saturate the network and result in delay or loss of message...

Since the 1960s, the incidence of malignant mesothelioma in Canada has increased dramatically because of work-related asbestos exposures. Treatment options are limited. Although chemotherapy is now an accepted standard in the management of advanced disease, uncertainty surrounds the roles of radical surgery and radiation. In March 2007, a symposium was held in Vancouver, B.C., to review the cur...

STUDY DESIGN Prospective field study of work exposure and changes in back function. OBJECTIVE Quantify dynamic physical exposures in the workplace and their association with decreases in kinematic back function (indicative of low back pain [LBP]). SUMMARY OF BACKGROUND DATA Previous epidemiologic studies of work have measured gross categories of exposure and found moderate relationships wit...

OBJECTIVE Childhood trauma is associated with negative perinatal health outcomes including mood disorders and shorter gestation. However, effects of early life exposures on maternal biology are poorly delineated. This study examined associations between childhood trauma and inflammation, as well as the mediating role of obesity in this relationship. METHOD This study examined a racially diver...

background: poinsettia (euphorbia pulcherrima), holly (ilex opaca) and mistletoe (phoradendron flavescens) adorn homes during the christmas and new year holiday season and create the potential for curious children to sample their colorful leaves and enticing berries. this study was aimed to review the american association of poison control centers national poison data system (aapcc npds) to des...
