MAS in adults may not be as rare as was once thought, although the clinical features of MAS in adults often differ from those seen in children. The MAS mortality in adults is far higher than that for children. A diagnosis of MAS should be considered when a patient with rheumatic disease presents with prolonged high fever, peripheral cytopenia and liver failure. Collection of bone marrow aspirates is critical for accurate diagnosis and MAS therapy should begin as early as possible.
Background The aim of this study was to investigate the associations of osteosarcopenic obesity (OSO) and its components with complete blood cell count-derived inflammation indices. Methods In this cross-sectional study, data of 648 participants aged ≥60 years (men/women: 232/416, mean age: 67.21 ± 6.40 years) were collected from January 2018 to December 2020. Areal bone mineral density and body fat percentage were used to define osteopenia/osteoporosis and obesity, respectively. The criteria of the 2019 Asian Working Group for Sarcopenia were used to diagnose sarcopenia. Based on the number of these conditions, participants were divided into four groups: OSO/0, OSO/1, OSO/2, and OSO/3. Logistic regression analysis was conducted to identify associations between blood cell count-derived inflammation indices and the number of disorders with abnormal body composition. Results Systemic inflammation response index (SIRI), white blood cells, neutrophil-to-lymphocyte ratio (NLR), aggregate inflammation systemic index (AISI), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) showed statistically significant differences among the four groups (P < 0.05). Unlike in the OSO/0 group, in all other groups, AISI, SIRI, PLR, and NLR were significantly associated with increased likelihood of having multiple disorders with abnormal body composition after adjustment for confounders (P < 0.0001 for all). However, LMR showed an inverse correlation with the number of these conditions (P < 0.05). Conclusion Higher SIRI, AISI, NLR, and PLR values and lower LMR values are closely associated with OSO and its individual components—osteoporosis, sarcopenia, and obesity—in older adults, suggesting that the value of these indices in the evaluation of OSO warrants further investigation.
BackgroundDepression is one of the greatest public health problems worldwide. The potential benefit of social participation (SP) on mental health has been widely acknowledged. Nevertheless, a few studies have used propensity score matching (PSM) to reduce the influence of data bias and confounding variables. This study explored the effect of social participation on depression among middle-aged and older Chinese persons through a PSM method, considering the frequency, type, and quantity of SP. Effects were compared among different age groups, genders, and places of residence.MethodsThe datasets were obtained from the 2018 wave of the China Health and Retirement Longitudinal Study. A total of 9,404 respondents aged 45 and above were included in the study. PSM and ordinary least squares methods were used to estimate the effect of social participation on depression.ResultsPSM estimation results showed that SP had a significantly positive effect on decreasing depression scores (p < 0.001) by 0.875–0.898 compared with persons without SP. All types of SP had a significantly positive effect (p < 0.001), and participating in community activities had the largest effect (β = −1.549 to −1.788, p < 0.001). Higher frequency of participation and more types of SP promoted lower depression scores; subgroup analyses revealed that the promotion effect was significantly greater among women, those aged ≥75 years, and those living in urban areas.ConclusionPSM indicated that SP could alleviate the depression of middle-aged and older Chinese persons. Targeted measures should be adopted to promote SP and thereby improve mental health and promote healthy and active aging.
While osteoporosis is a chronic disease caused by multiple factors, it is also a risk factor for fractures. At present, numerous risk factors for osteoporosis and secondary fractures have been identified, including sunlight, physical fitness, gender, age, trauma, dietary habits, tobacco, alcohol, drugs, air quality, and genetics. Despite that factors such as long winters, short daylight hours, less daily physical activity, air pollution, low calcium and high salt diet, and sedentary lifestyle could negatively impact the bones of residents in the alpine regions of northern China, the direct effect of low-temperature stimulation on bone growth and development remains unclear. In this study, by reviewing current research progress related to osteoporosis and fracture risk in northern China, we proposed appropriate preventive measures for different risk factors to reduce the occurrence of osteoporosis and fracture in cold areas of northern China.
