Potential Adverse and Allergic Reactions from Complementary and Alternative Medicine and Dietary Supplements

<p/> <p>Complementary and alternative medicine and dietary supplements are often used by patients. A detailed examination of each preparation used by four patients was carried out. Seven such preparations with the potential to cause bleeding, cardiovascular and central nervous system side effects, and allergic food reactions are described. They were taken by both Asian and Caucasian patients, were purchased locally, and were used for allergic and nonallergic disorders. Inquiry into their use is important to prevent potential adverse and allergic reactions. There should be a higher standard of regulation for such products.</p

Periodontal conditions in adult Southern Chinese

Periodontal diseases remain a concern in adult populations, but there have been no systematic descriptions of periodontal conditions, which have included periodontal attachment loss, among Southern Chinese. The main aim of this report is to describe the periodontal conditions in adult Chinese and to investigate factors that may have influenced periodontal attachment loss. Subjects were recruited from urban and rural survey sites throughout Guangdong. In total, 1572 35- to 44-year-old subjects and 1286 65- to 74-year-old subjects completed a structured interview and underwent a periodontal examination, which included the Community Periodontal Index (CPI) and periodontal Attachment Loss (ALoss) recordings. Calculus was found as the highest CPI score in 61-68% of the 35- to 44-year-old subjects and in 54-57% of the 65- to 74-year-olds. Shallow pockets were found as the highest CPI score in about one-third of both the urban and the rural subjects in both age groups, and deep pockets in 3-7% of the subjects. ALoss was more prevalent than pockets in both age groups. On the basis of the ALoss recordings, about one-third of the subjects in both age groups were categorized as exhibiting considerable ALoss for their age. In both age groups, logistic regression analysis indicated that being male, wearing partial dentures, and reporting less frequent toothbrushing were found to be associated with considerable ALoss.published_or_final_versio

Illness Experiences among Chinese College Students: A Negotiation Process between Social Connections and Protection of Self-Image

This study explored the experience of illness in relation to self-image, biographical disruption, and the process of coping through semi-structured interviews with students of a university in China. Twelve students were recruited under three categories, having a physical chronic illness, mental health illness, and chronic multiple morbidities. Indepth interviews were conducted and content analyses were applied to their recordings to identify major themes and subordinate themes in the illness experience. Results showed a distorted sense of self and biographical disruptions in young adulthood were common, as reported by the respondents. Students tried to cope with these disruptions with both individual strengths and social support, but not always with positive results. Reconstruction of self, in the analysis of illness experiences, was found a crucial strategy in overcoming disruptions. Social support of evaluative nature facilitated the adoption of the reconstruction strategy. A network-building approach is recommended for student services in higher education whereas further research is necessary to understand the processes of self-reconstruction

Asymmetric-detection time-stretch optical microscopy (ATOM) for high-contrast and high-speed microfluidic cellular imaging

High-throughput cellular imaging is acclaimed as captivating yet challenging in biomedical diagnostics. We have demonstrated a new imaging modality, asymmetric-detection time-stretch optical microscopy (ATOM), by incorporating a simple detection scheme which is a further advancement in time-stretch microscopy - a viable solution to achieve high-speed and high-throughput cellular imaging. Through the asymmetric-detection scheme in ATOM, the time-stretch image contrast is enhanced through accessing to the phase-gradient information. With the operation in the 1 μm wavelength range, we demonstrate high-resolution and high-contrast cellular imaging in ultrafast microfluidic flow (up to 10 m/s) by ATOM - achieving an imaging throughput equivalent to 100,000 cells/sec. © 2014 SPIE.published_or_final_versio

Coronal and root caries in Southern Chinese adults

Southern China is the most prosperous part of China, but information useful for oral care planning is very limited. A large-scale epidemiological survey was conducted in 1996-97. The objectives of this report were to describe the coronal and root caries of the adult Southern Chinese and to analyze the influence of selected demographic and socio-economic factors on the disease pattern. A total sample of 1573 35- to 44-year-olds and 1515 65- to 74-year-olds from 8 urban and 8 rural survey sites in Guangdong Province participated in an oral health interview and underwent clinical examination. World Health Organization examination procedures and diagnostic criteria were used. The weighted mean DMFT scores of the middle-aged and the elderly subjects were 4.8 and 16.1, respectively. People living in rural areas had a higher DMFT score than those living in urban areas (4.9 vs. 4.3 in the 35- to 44-year-olds and 16.5 vs. 14.7 in the 65- to 74-year-olds). In both age groups, MT was the major component of the DMFT score. Analysis of covariance showed that women and those who were economically less well off had higher DMFT scores in both age groups. The weighted prevalence rates of decayed/filled roots were 12% and 37%, with a mean of 0.2 and 0.7 teeth affected, in the middle-aged and the elderly, respectively. In conclusion, socio-economic factors had a considerable effect on the dental caries status of adults in Southern China.published_or_final_versio

Utilization of dental services in Southern China

A population's utilization of dental services is an important parameter in oral health care planning, which has rarely been studied in China. The objectives of this report were to describe the dental service utilization pattern of middle-aged and elderly Chinese and to analyze the influence of selected variables on the use of dental services. A Guangdong Province population of 1573 35- to 44-year-olds and 1515 65- to 74-year-olds recruited from urban and rural communities was interviewed in their local dialect. It was found that 23% of the middle-aged and 24% of the elderly subjects had visited a dentist within the preceding year. The two most commonly cited reasons for not having seen a dentist for at least 3 years were: no perceived need, and no serious dental problems. Among subjects who had visited a dentist within 3 years, the 3 most commonly received treatments were: fillings, extractions, and dental prostheses. Furthermore, a logistic regression analysis showed that women, subjects who lived in urban areas, were better educated, were wealthier, and had better oral health knowledge were more likely to be a recent dental service user. In conclusion, dental service utilization among the adult Southern Chinese was found to be low, problem-driven, and influenced by some socio-economic factors.published_or_final_versio
