To evaluate lesion detection of MRI in knee joint osteoarthritis in patients with symptoms of pain, the correlation between MRI findings and varying degrees of reported pain was assessed. Twenty-eight patients (31 knees) with osteoarthritis were recruited for this study. The degree of knee pain was assessed by VRS scores. The knees were evaluated by plain film radiograph utilizing Kellgren-Lawrence scores. Multiple MR sequences were performed on a 1.5T MR-system, including sagittal and coronal dual fast spin echo (TR/TE 3660/11/120 ms, slice thickness 5 mm), coronal spin echo T1-weighted (TR/TE 360/9 ms, slice thickness 5 mm), sagittal fat saturated 3D-spoiled gradient-recalled echo (TR/TE 50/6 ms; slice thickness 1.5 mm; flip angle 40 degrees ), and 3D steady-state free precession (TR/TE 6/2.2 ms; slice thickness 1.6 mm; flip angle 30 degrees ) pulse sequences for the purpose of detecting abnormities of cartilage, menisci, the anterior cruciate ligaments, bone marrow edema-like lesions, osteophytes, synovitis, and joint effusions. MR findings were compared with the degree of pain using Fisher exact test with P values less than 0.05 indicating a statistically significant difference. The results showed that, of the 31 knees evaluated, mild pain was reported in 11 and severe pain in the remainder. Kellgren-Lawrence scores of all 31 evaluated OA knees were as follows: grade 1 lesions (n=6), grade 2 lesions (n=14), grade 3 lesions (n=8), and grade 4 lesions (n=3). Articular cartilaginous defects were found in 37.1% of knees. Abnormalities of the menisci and anterior cruciate ligaments, bone marrow edema-like lesions, osteophytes, synovitis, and joint effusions were detected in 32.3%, 38.7%, 45.2%, 100%, 15.1% and 67.7% of knees, respectively. Of these variables, only the differences in prevalence of joint effusions were significantly different in the mild and severe pain groups (P=0.004). It is concluded that MRI evaluates the entire joint structure of the osteoarthritic knee, demonstrating abnormalities of the cartilage, menisci, and anterior cruciate ligaments as well as bone marrow edema-like lesions, osteophytes, synovitis, and joint effusions. The difference in pain grading between OA patients reporting mild and severe degrees of pain is related to the presence of joint effusion.

Objective: To investigate the drinking status and associated factors in adults in China. Methods: Based on the 2010-2012 China National Nutrition and Health Survey (CNNHS), a total of 135 824 participants aged ≥18 were included in this cross-sectional analysis. Multivariable logistic regression model was used to investigate the associated factors for drinking status. Results: The overall drinking rate was 30.5% in Chinese adults, 53.8% in men, and 12.2% in women. The excessive drinking rate was 14.0% in men and 1.1% in women. The daily drinking rate was 25.7% in men and 10.9% in women. Men mainly consumed multi-type wines, but women preferred beer. The overall harmful drinking rate was 7.1%. The excessive drinking rate, daily drinking rate, and harmful drinking rate increased first but then declined with age. All the four rates were positively related with physical activity. Conclusions: The drinking rate, excessive drinking rate, daily drinking rate and harmful drinking rate were high in adults in China. Drinking status was associated with age, sex, marital status, education level, smoking status and physical activity.

Objective: To evaluate the frailty status and understand the relationship between the incidence of fall and frailty status in the elderly in Beijing. Methods: A cross-sectional study was conducted in old people aged ≥60 years in Longtan community of Dongcheng district in Beijing from November 2015 to January 2016. The information about any fall during the past year and frailty status of the elderly were collected with a standardized structured questionnaire in face-to-face interviews. The frailty status of elderly people was assessed with frailty index (FI) method. Logistic regression analysis was used to explore the relationship between fall and frailty status among the elderly. Results: Among 1 557 old people surveyed, the incidence of fall was 17.8% (277/1 557) during the past year. The incidence of fall in women (21.0%, 192/277) was statistically higher than that in men (13.3%, 85/277) (χ(2)=15.288, P=0.000). The median (quartile) value of FI of the elderly surveyed was 0.09 (0.08); and women had a higher FI median value than men [0.10 (0.08) versus 0.08 (0.07)](Z=5.376, P=0.000). The median FI value (quartile range) of 277 old people with history of fall in previous year was 0.12 (0.11), which was higher than the median FI value of 0.08 (0.07) of 1 280 old people without fall history (Z=7.501, P=0.000). Logistic regression analysis showed that higher FI value was associated with more risks for fall; and FI value showed the greatest impact on the incidence and frequency of fall (OR=1.093, 2.234) compared with other related factors of fall, such as age and gender. Conclusion: Frailty status has a greater impact on both incidence and frequency of fall compared with other factors in elderly people in Beijing; more attention should be paid to weak and old adults in the prevention of fall.

Objective: To understand the overweight rate and obesity rate in middle-aged and elderly people in urban area of Beijing, and analyze the changes of body composition and resting metabolic rate with age. Methods: From November 2014 to December 2015, body composition measurement and resting metabolic rate detection were conducted among 858 people aged 51 to 99 years, including 760 men, 98 women, who received physical examination at Beijing Hospital. Results: The overweight rate was 51.4%, and the obesity rate was 16.9%. The overweight rate was 26.5% and the obesity rate was 14.3% in women, significantly lower than those in men (54.6% and 17.2%) (P<0.001). The distribution of skeletal muscle volume, muscle index, body fat percentage, visceral fat area and resting metabolic rate in different age groups were different (P<0.001). In the normal weight group, the skeletal muscle volume, muscle index and resting metabolic rate in age group ≥80 years decreased obviously (P<0.05). At the same time, the body fat percentage and visceral fat area increased obviously (P<0.05). However, the skeletal muscle volume, muscle index and resting metabolic rate of the overweight and obese groups began to decrease obviously in age group 70- years (P<0.05), and the decrease in age group ≥80 years was more obvious. At the same time, body fat percentage and visceral fat area increased significantly in age group 70- years (P<0.05). Conclusion: The overweight and obesity rates were high in the middle-aged and elderly people in the urban area of Beijing, and the rates were higher in men than in women. With the increase of age, the skeletal muscle volume, muscle index and resting metabolic rate gradually decreased, while the percentage of body fat and visceral fat area increased; Overweight and obese people had earlier changes in body composition and resting metabolic rate.

Background: Anti-Mullerian hormone (AMH) levels have been used as an invaluable tool in reproductive medicine for over a decade, especially in predicting ovarian reserve and follicular response during in vitro fertilization (IVF) cycles. Age-specific reference values of AMH levels have been derived from mostly Western and few Asian population groups but none from the Philippines. In this study, we attempted to determine the first age-specific AMH reference values from infertile Filipino women to be able to provide local infertility centers a guide in treating Filipinos and those with similar racial and lifestyle characteristics. Materials and Methods: This was a retrospective cross-sectional study that was conducted at the Center for Advanced Reproductive Medicine and Infertility at St. Luke's Medical Center Global City. Age, serum AMH levels, body mass index (BMI), and cause of infertility of Filipino women who underwent IVF from August 2015 to March 2020 were taken. AMH was assayed using the automated Access AMH Immunoassay (Beckman Coulter). Results: A total of 1463 women who underwent IVF and with valid AMH results were initially found but only 1233 were included in the study. Mean age was 36.67 + 4.35 years and mean BMI was 24.43 + 4.14 kg/m2. There was minimal effect of BMI on AMH levels and increasing age (R2 = 0.0068), but there were significant differences of mean AMH levels among the general causes of infertility. The mean and median AMH values decreased with advancing age (R2 = 0.1391) although the mean values were consistently higher than the median values. The mean level of the AMH was 2.32 ± 1.90 ng/mL with a 0.16 ng/ml (confidence interval: 0.14–0.19 ng/ml) level decrease per year of increase in age. By age category, the following were the derived AMH values (ng/ml) at the 25th to 75th percentiles: 25–29 = 1.52–4.92; 30–34 = 1.60–4.10; 35–39 = 0.95–3.13; 40–44 = 0.44–1.99; 45 = 0.47–1.08. The mean AMH in this study appears to be similar to several but lower than most other reported AMH nomograms from other population groups. Conclusion The first age-specific AMH reference values for infertile Filipino women are presented and may serve as a useful diagnostic marker in local infertility centers, especially those treating Filipino patients or others with similar characteristics.

Objective: To explore the influencing factors related to thyroid carcinoma. Methods: Matched by sex, age and original residential areas, 659 pairs of cases and controls were recruited and studied. Methods including both single factor analysis and multivariate conditional logistic regression analysis were carried out to identify the influencing factors. Results: Multivariate conditional logistic regression analysis showed that higher education, being diabetic, alcohol intake, tea drinking, occupational physical activity and the frequency of eating fishes/eggs etc., were potentially protective to thyroid carcinoma. Depression, personal history of CT examination and less salt intake seemed to be risk factors on thyroid carcinoma. For males, factors as alcohol intake, tea drinking, occupational physical activity and frequent egg-eating appeared protective. For females, higher education, diabetes, tea drinking, occupational physical activity, frequent consumption of fishes/eggs, short duration of menstruation appeared as possibly protective. Conclusion: Higher education, diabetes, alcohol intake, tea drinking, occupational physical activity, frequent consumption of fishes/eggs, depression, personal history of CT examination and less salt intake served as potential influencing factors to thyroid carcinoma.
