Accuracy of Mean Value of Central Venous Pressure from Monitor Digital Display: Influence of Amplitude of Central Venous Pressure during Respiration.

Background A simple measurement of central venous pressure (CVP)-mean by the digital monitor display has become increasingly popular. However, the agreement between CVP-mean and CVP-end (a standard method of CVP measurement by analyzing the waveform at end-expiration) is not well determined. This study was designed to identify the relationship between CVP-mean and CVP-end in critically ill patients and to introduce a new parameter of CVP amplitude (ΔCVP= CVPmax - CVPmin) during the respiratory period to identify the agreement/disagreement between CVP-mean and CVP-end.

Associated Factors of Oral Health-related Quality of Life in Chinese Adolescents Aged 12-15 Years.

Unlabelled: adolescents aged 12 to 15 years based on the 4th National Oral Health Survey and to explore its associated factors.

Cost-effectiveness Analysis of Comprehensive Oral Health Care for Severe Early Childhood Caries in Urban Beijing, China.

Objective: To evaluate the cost-effectiveness of comprehensive oral health care for severe early childhood caries (S-ECC) in urban Beijing, China.

Methods: A randomised cluster sampling method was used to select 187 children aged 3 to 5 years with S-ECC from two kindergartens in urban Beijing. Comprehensive oral health care and questionnaires for the parents/guardians were provided to the test group, while an oral health examination and questionnaires for the parents/guardians were provided to the control group.

Utilisation of Oral Health Services and Economic Burden of Oral Diseases in China.

Objective: To evaluate the use of oral health services, the economic burden of oral diseases and related influential factors in China.

Method: Using the multistage, stratified, equal proportion, random sampling method in the 4th National Oral Health Survey of China conducted in 2015 to 2016, residents aged 3 to 5 years, 12 to 15 years, 35 to 44 years, 55 to 64 years, and 65 to 74 years respectively were recruited, clinically examined and answered a questionnaire. Utilisation of oral health services were assessed in all the age groups and the economic burden of oral diseases in the past 12 months were assessed in the 3 to 5 years and 35 to 74 year-old groups.

Oral Health Knowledge, Attitudes, Behaviour and Oral Health Status of Chinese Diabetic Patients Aged 55 to 74 Years.

Objective: To understand the oral health knowledge, attitude, behaviour and oral health status of Chinese diabetic patients so as to facilitate the development of oral health education programmes for diabetic patients in China.

Method: A face-to-face questionnaire was conducted for 1,024 diabetic patients and 8,030 non-diabetic people aged 55 to 74 years old in order to understand their oral health knowledge, attitudes, and behaviour. Oral health examination was implemented including caries, gingival bleeding, dental calculus, periodontal attachment loss, etc.
