2(cid:9) DENTAL TRIBUNE(cid:9) Pakistan Edition(cid:9)January 2017 Researchers to investigate oral bacterium as possible cause of infective endocarditis DT International B BUFFALO, N.Y., USA: At t h e e n d o f l a s t y e a r, researchers at the University at Buffalo School of Dental Medicine announced that they had received a $239,000 grant from the National Institute of Dental and Craniofacial Research to study the m e c h a n i s m s o f Streptococcus gordonii. The bacterium is a normal t h e o r a l p a r t o f m i c r o b i o m e . I t i s , however, suspected of causing blood clots and triggering life-threatening endocarditis once it has entered the bloodstream t h r o u g h b l e e d i n g gingivae.(cid:9) sometimes digest, foreign particles, such as bacteria.(cid:9) "Our white blood cells have a number of ways of destroying invading microbes, but somehow these bacteria manage to escape, sometimes from going bad."(cid:9) Kay's team hypothesizes that S. gordonii survives inside the phagocytes by resisting the cell's kill mechanisms, partly owing to certain genetic predispositions. Therefore, the s t u d y w i l l a i m a t identifying genes that may increase the bacteria's survival inside the white blood cells by turning off specific genes within the microbes and monitoring the interactions.(cid:9) In addition, the researchers will examine whether the phagocytes are modified or damaged during the killing process, and how the maturation process of white blood cells affects their ability In a new study, researchers will study oral bacteria that may contribute to the development of infective heart disease. The research will be carried out by a laboratory team led by Dr. Jason Kay, an assistant professor in the Department of Oral Biology, who specializes in the study of phagocytes that have the ability to ingest, and surviving inside the cells meant to kill it. How this occurs is not understood," Kay said. "Once we understand how this survival occurs, the knowledge will allow us to develop treatments that prevent normally good bacteria to destroy the bacteria.(cid:9) Understanding these interactions will help clinicians better prevent one of the causes of infective endocarditis and ultimately lead to new treatments for the disease.

A new study focusing on factors determining dental visiting patterns of Asians in the U.S. has shown that length of stay in the country is a significant factor affecting dental service utilization among this group.(cid:9) Although the Asian population is the second fastest- growing group in the U.S., little research on Asian immigrants and the various nationalities of this category has been done. In order to address this issue, the researchers evaluated health care data of 2,948 dentate adult Asian immigrants. They studied whether acculturation, measured by length of stay in the U.S., English language proficiency and U.S. citizenship, had affected their dental visiting patterns in the previous 12 months. (cid:9) They found that, overall, Asian immigrants, with the exception of Filipinos, made significantly low use of dental services. Despite cultural and attitude differences toward dental care within Asian subgroups, enabling factors like affordability, familiarity with health care system and oral health status had important effects on dental service utilization. The most prominent factor affecting utilization proved to be dental insurance coverage.(cid:9) English language proficiency, however, which is often considered the main barrier to health care services, was not a significant correlate of having a dental visit. However, length of stay in the U.S. (> 5 years) appeared to be the Asian immigrants in the U.S. do not use dental services as often as non-Hispanic whites. most significant factor among Asians. (cid:9) "We hypothesize that this could be because longer stays in the U.S. allow for immigrants to gain improved familiarity with health care system, increases health literacy, and social support networks," said Dr. Huabin Luo, assistant professor at the East Carolina University Department of Public Health, North Carolina, who led the study, together with Prof. Bei Wu from the New York University Rory Meyers College of Nursing. (cid:9) The researchers concluded that health care professionals need to pay more attention to providing oral health education among newer immigrants and that interpreting services may be necessary. There is an apparent need for greater dental care promotion among these groups, especially in the beginning stages of their arrival, they said.
