RESUMO
BACKGROUND: Microcirculatory dysfunction is associated with increased morbidity and mortality in cardiac surgery patients. This study aimed to investigate the association between preoperative retinal microcirculation evaluated using optical coherence tomography angiography (OCTA) and perioperative outcomes in patients with congenital heart disease (CHD). METHODS: This prospective, observational study was performed from May 2017 to January 2021. OCTA was used to automatically quantify the vessel density (VD) of the superficial capillary plexus, deep capillary plexus (DCP), and radial peripapillary capillary (RPC) preoperatively. The primary outcome was excessive postoperative bleeding, defined as bleeding volume > 75th percentile for 24-hour postoperative chest tube output. The secondary outcome was composite adverse outcomes, including one or more operative mortalities, early postoperative complications, and prolonged length of stay. The association between retinal VD and outcomes was assessed using Poisson regression. RESULTS: In total, 173 CHD patients who underwent cardiac surgery were included (mean age, 26 years). Among them, 43 (24.9%) and 46 (26.6%) developed excessive postoperative bleeding and composite adverse outcomes, respectively. A lower VD of DCP (odds ratio [OR], 1.24; 95% confidence interval [CI], 1.08-1.43; P = 0.003) was independently associated with excessive postoperative bleeding, and a lower VD of RPC (OR, 1.97; 95% CI, 1.08-3.57; P = 0.027), and DCP (OR, 2.17; 95% CI, 1.08-4.37; P = 0.029) were independently associated with the postoperative composite adverse outcomes. CONCLUSION: Preoperative retinal hypoperfusion was independently associated with an increased risk of perioperative adverse outcomes in patients with CHD, suggesting that retinal microcirculation evaluation could provide valuable information about the outcomes of cardiac surgery, thereby aiding physicians in tailoring individualized treatment.

OBJECTIVES: To explore factors that influenced the health resource allocation and utilisation before and after COVID-19, and subsequently offer sensible recommendations for advancing the scientific distribution of health resources. DESIGN: A longitudinal survey using 2017-2020 data, which were collected for analysis. SETTING: The study was conducted based on data collected from the Health Commission of Guangdong Province's website. OUTCOME MEASURES: Eight health resource indicators and four health resource utilisation indicators were included in the factor analysis. Four indices were calculated to measure the inequality in health resource allocation and utilisation. We analysed factors for the inequality indices using the recentred influence function index ordinary least squares decomposition method. RESULTS: The health resource inequality indices peaked in 2020 (Gini coefficient (Gini): 0.578, Absolute Gini coefficient (AGini): 1.136, Concentration Index (CI): 0.417, Absolute CI (ACI): 0.821), whereas the health resource utilisation inequality indices declined year by year, thus reaching their lowest point in that same year. The majority of inequality indices in the annual change of health resource allocation were at their lowest in 2020 (Gini: -1.672, AGini: 0.046, CI: -0.189, ACI: 0.005), while the use of health resources declined dramatically, showing a negative growth trend. The inequality indices of health resource allocation and utilisation in 2020 were affected by a number of variables, including the COVID-19 level, (p<0.05), while the proportion of expenditure on public health was the most significant one. CONCLUSIONS: Guangdong Province's health resource allocation and utilisation were still concentrated in economically developed regions from 2017 to 2020. The health resource allocation inequality indices increased, especially under COVID-19, but the health resource utilisation inequality indices decreased. Measures should be taken to adjust the health resource allocation scientifically, which will fulfil the changing needs and the use of resources more efficiently. One effective measure is reasonably increasing the proportion of expenditure on public health.

OBJECTIVE: To investigate the reliability and validity of Healthy Fitness Measurement Scale Version 1.0 (HFMS V1.0) for different population cohorts in the city of Guangzhou, Guangdong, China and to provide evidence and tools for further evaluation of healthy fitness of Chinese population and related factors. DESIGN: Cross-sectional study. SETTING: Urban neighbourhood and Medical University. PARTICIPANTS: Elderly people (n=393; mean age 68.27±6.38 years; 53.18% male), university students (n=390; mean age 19.29±1.29 years; 38.21% male) and urban residents (n=393; mean age 32.23±9.41 years; 44.78% male). PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcomes were evaluated the reliability and validity of HFMS V1.0 by internal consistency evaluation, split-half reliability, test-retest reliability, convergent and discriminant construct validity, and factor analysis. RESULTS: The Cronbach's α coefficients for HFMS V1.0 were all greater than 0.85 for overall scale of total samples and three individual groups, and the split-half reliability and intragroup correlation coefficients were both greater than 0.70 (p<0.01). The correlation of each item, dimension and subscales ranged from 0.52 to 0.91 (p < 0.01). A total of 10 factors were screened by exploratory factor analysis with the cumulative contribution rate of 61.40%, basically consistent with the theoretical structure of scale. The confirmatory factor analysis indicated good fit: CMIN/DF=3.45, root mean square error of approximation=0.05, GFI=0.91, AGFI=0.90, IFI=0.90, comparative fit index=0.90. CONCLUSION: HFMS V1.0 showed acceptable reliability and validity in the test of healthy fitness of general population in Guangzhou. This scale could be a reliable measurement tool for evaluation of healthy fitness and potential risk factors.

BACKGROUND: Femoral neck fractures in elderly patients typically warrant operative treatment and are related to high risks of mortality and morbidity. As early hip arthroplasties for elderly femoral neck fractures are widely accepted, rapid predicting models that allowed quantitative and individualized prognosis assessments are strongly needed as references for orthopedic surgeons during preoperative conversations. METHODS: Data of patients aged ≥ 65 years old who underwent primary unilateral hemiarthroplasty or total hip arthroplasty due to femoral neck fracture between January 1st, 2012 and June 30th, 2019 in our center were collected. Candidate variables included demographic data, comorbidities, and routine preoperative screening tests. The main outcomes included 1-year mortality and free walking rate after hip arthroplasty. Patients were randomly divided into derivation and validation groups in the ratio of three to one. Nomograms were developed based on multivariable logistic regressions of derivation group via R language. One thousand bootstraps were used for internal validation. Those models were further tested in the validation group for external validation. RESULTS: The final analysis was performed on 702 patients after exclusion and follow-up. All-cause 1-year mortality of the entire data set was 23.4%, while the free walking rate was 57.3%. Preoperative walking ability showed the biggest impact on predicting 1-year mortality and walking ability. Static nomograms were created from the final multivariable models, which allowed simplified graphical computations for the risks of 1-year mortality and walking ability in a certain patient. The bias-corrected C index of those nomograms for predicting 1-year mortality in the derivation group and the validation group were 0.789 and 0.768, while they were 0.807 and 0.759 for predicting postoperative walking ability. The AUC of the mortality and walking ability predicting models were 0.791 and 0.818, respectively. CONCLUSIONS: Our models enabled rapid preoperative 1-year mortality and walking ability predictions in Asian elderly femoral neck fracture patients who planned for hip arthroplasty, with adequate predictive discrimination and calibration. Those rapid assessment models could help surgeons in making more reasonable clinical decisions and subsequently reducing the risk of potential medical dispute via quantitative and individualized prognosis assessments.

INTRODUCTION: Suboptimal health status (SHS), an intermediate state between chronic disease and health, is characterized by chronic fatigue, non-specific pain, headaches, dizziness, anxiety, depression, and functional system disorders with a high prevalence worldwide. Although some lifestyle factors (e.g. smoking, alcohol consumption, physical exercise) and environmental factors (e.g. air quality, noise, living conditions) have already been studied, few studies can comprehensively illustrate the associations of lifestyle and environment factors with general, physical, mental, and social SHS. METHODS: A cross-sectional study was conducted among 6750 urban residents aged 14 years or over in five random cities from September 2017 to September 2018 through face-to-face questionnaires. There were 5881 valid questionnaires with a response rate of 87%. A general linear model and structural equation model were developed to quantify the effects of lifestyle behaviors and environment factors on SHS. RESULTS: The detection rates of general, physical, mental, and social SHS were 66.7, 67.0, 65.5, and 70.0%, respectively. Good lifestyle behaviors and favorable environment factors positively affected SHS (P < 0.001). Lifestyle behaviors had the largest effect on physical SHS (ß = - 0.418), but the least on social SHS (ß = - 0.274). Environment factors had the largest effect on mental SHS (ß = 0.286), but the least on physical SHS (ß = 0.225). CONCLUSIONS: Lifestyle behaviors and environment factors were important influencing factors of SHS. Physical SHS was more associated with lifestyle. Lifestyle and environment were similarly associated with mental and social SHS.

OBJECTIVES: The association between weak hand grip strength (HGS) and stroke recovery has been studied; however, few studies focused on the association of HGS with stroke prevalence and incidence. METHODS: A prospective cohort baseline study of a nationally representative sample in Chinese adults aged 45 years and older in 2011 was followed up in 2015. 8871 participants without stroke at baseline were followed. The associations of HGS and its changes with stroke prevalence and incidence were investigated using logistic regression models and Cox proportional hazards regression models. RESULTS: Association of HGS and stroke prevalence was significant. HGS weakness significantly increased risk of stroke incidence, with 89.3% higher risk when compared to normal HGS. During 35,263 person-years of follow-up, 112 stroke patients occurred. The four-year incidence rate ratio of stroke for participants with a HGS weakness was 2.15, compared to normal HGS participants. HGS changes in weakness/weakness from 2011 to 2015(D-HGS) and normal/weakness D-HGS had higher risks of stroke incidence when compared with those who had normal/normal D-HGS. CONCLUSIONS: HGS weakness and decline of HGS were associated with stroke incidence for adults aged 45 years and older in China.

BACKGROUND: The coexistence of multiple chronic conditions is very common in cardiovascular disease (CVD). However, the prevalence of CVD multimorbidity in China and its influence on life satisfaction have not been reported. This study aimed to investigate the proportions of 12 chronic comorbid diseases in CVD and the associations of multimorbidity with life satisfaction in patients with CVD. METHODS: We conducted a cross-sectional study in a nationally representative sample of 3478 participants with CVD aged 45 years or more who participated in the China Health and Retirement Longitudinal Study 2015. Correlations of multimorbidity with 12 chronic diseases in CVD and life satisfaction were investigated using logistic regression models, after adjusting for 12 covariates. RESULTS: The proportion of multimorbidity among participants with CVD was 93.3% (89.4% for middle-aged adults and 95.4% for older adults; 92.9% for men and 93.5% for women). The proportion of participants with CVD multimorbidity who were dissatisfied with life was 11.2%, significantly higher than those without any chronic diseases (χ2=5.147, p=0.023). Life satisfaction in patients with CVD decreased with increased number of comorbidities (χ2=45.735, p<0.001). Kidney disease (OR=1.933, 95% CI: 1.483 to 2.521), memory-related diseases (MRDs) (OR=1.695, 95% CI: 1.149 to 2.501) and dyslipidaemia (OR=1.346, 95% CI: 1.048 to 1.729) were significantly associated with reduced life satisfaction when adjusting for 12 covariates. CONCLUSIONS: In this nationally representative cross-sectional study, life satisfaction was reduced by multimorbidity of CVD. Kidney disease had the greatest influence on life satisfaction in patients with CVD, followed by dyslipidaemia and MRDs. Our study emphasises the importance of preventing of chronic diseases in adults with CVD.

BACKGROUND: Suboptimal health status (SHS) among urban residents is commonplace in China. However, factors influencing SHS have not been thoroughly explored, especially with regard to the effects of internal factors (e.g., personality and health awareness) on SHS. METHODS: A cross-sectional study was conducted with a nationally representative sample of 5460 Chinese urban residents..SHS was measured using the Suboptimal Health Mesurement Scale Version 1.0. Demographic information, and information pertaining to lifestyle behaviors, environmental factors, and internal factors were abtained through a questionnaire. The associations between demographic information, lifestyle behaviors, environmental factors, internal factors and SHS were assessed using logistic regression. RESULTS: Of the 5460 participants (with a mean age of 41.56 ± 16.14 years), 2640 (48.4 %) were men. Out of 36 variables, 23 were significantly associated with SHS: age (odds ratio [OR]: 1.014), an education level of high school/junior college (OR: 1.443) , marital status (OR: 1.899), area of registered permanent residence (OR: 0.767), monthly household income (p < 0.001) , exposure to second-hand smoke (p = 0.001), alcohol drinking (OR: 1.284), bad eating habits (OR: 1.717), not sleeping before 11 p.m. every day (p = 0.002), spending time online more than five hours a day (OR: 1.526), having a good relationship with parents during one's growth period (OR: 0.602), living with good quality air (OR:0.817), living in not crowded conditions (OR:0.636), having a harmonious neighborhood (OR:0.775), having adequate fitness facilities (OR:0.783), one's health being affected by two-child policy (OR: 1.468) and medical policies (OR: 1.265) , high adverse quotient (OR: 0.488), many (≥3 kinds) interests and hobbies (OR: 0.617), mature and steady personality traits (OR: 0.469) , a high attention to one's health (OR: 0.833), and effective health promotion induced by leading a leisurely lifestyle (OR: 0.466) were significantly associated with SHS. CONCLUSIONS: All these variables were included demographic information, lifestyle behaviors, environmental factors and internal factors. Our study supports the benefits of controlling both internal and external factors in preventing suboptimal health.
RESUMO
BACKGROUND: Although medical intervention of periprosthetic bone loss in the immediate postoperative period was recommended, not all the patients experienced periprosthetic bone loss after total hip arthroplasty (THA). Prediction tools that enrolled all potential risk factors to calculate an individualized prediction of postoperative periprosthetic bone loss were strongly needed for clinical decision-making. METHODS: Data of the patients who underwent primary unilateral cementless THA between April 2015 and October 2017 in our center were retrospectively collected. Candidate variables included demographic data and bone mineral density (BMD) in spine, hip, and periprosthetic regions that measured 1 week after THA. Outcomes of interest included the risk of postoperative periprosthetic bone loss in Gruen zone 1, 7, and total zones in the 1st postoperative year. Nomograms were presented based on multiple logistic regressions via R language. One thousand Bootstraps were used for internal validation. RESULTS: Five hundred sixty-three patients met the inclusion criteria were enrolled, and the final analysis was performed in 427 patients (195 male and 232 female) after the exclusion. The mean BMD of Gruen zone 1, 7, and total were decreased by 4.1%, 6.4%, and 1.7% at the 1st year after THA, respectively. 61.1% of the patients (261/427) experienced bone loss in Gruen zone 1 at the 1st postoperative year, while there were 58.1% (248/427) in Gruen zone 7 and 63.0% (269/427) in Gruen zone total. Bias-corrected C-index for risk of postoperative bone loss in Gruen zone 1, 7, and total zones in the 1st postoperative year were 0.700, 0.785, and 0.696, respectively. The most highly influential factors for the postoperative periprosthetic bone loss were primary diagnosis and BMD in the corresponding Gruen zones at the baseline. CONCLUSIONS: To the best of our knowledge, our study represented the first time to use the nomograms in estimating the risk of postoperative periprosthetic bone loss with adequate predictive discrimination and calibration. Those predictive models would help surgeons to identify high-risk patients who may benefit from anti-bone-resorptive treatment in the early postoperative period effectively. It is also beneficial for patients, as they can choose the treatment options based on a reasonable expectation following surgery.

OBJECTIVE: Suboptimal health status (SHS), a third state between good health and disease, can easily develop into chronic diseases, and can be influenced by lifestyle and health consciousness. No study has surveyed the intermediation of health consciousness on the relationship between lifestyle and SHS. This study aimed to analyse the association of lifestyle and SHS, and intermediation of health consciousness in Chinese urban residents. DESIGN: A cross-sectional face-to-face survey using a four-stage stratified sampling method. PARTICIPANTS: We investigated 5803 Chinese urban residents aged 18 years and over. We measured SHS using the Sub-Health Measurement Scale V1.0. We adopted a structural equation model to analyse relationships among lifestyle, health consciousness and SHS. We applied a bootstrapping method to estimate the mediation effect of health consciousness. RESULTS: Lifestyle had stronger indirect associations with physical (ß -0.185, 95% CI -0.228 to -0.149), mental (ß -0.224, 95% CI -0.265 to -0.186) and social SHS (ß -0.216, 95% CI -0.257 to -0.179) via health consciousness than direct associations of physical (ß -0.144, 95% CI -0.209 to -0.081), mental (ß -0.146, 95% CI -0.201 to -0.094) and social SHS (ß -0.130, 95% CI -0.181 to -0.077). Health consciousness has a strong direct association with physical (ß 0.360, 95% CI 0.295 to 0.427), mental (ß 0.452, 95% CI 0.392 to 0.510) and social SHS (ß 0.434, 95% CI 0.376 to 0.490). Ratio of mediating effect of health consciousness to direct effect of lifestyle with physical, mental and social SHS was 1.28, 1.53 and 1.66, respectively. CONCLUSIONS: Health consciousness was more important in preventing physical, mental and social SHS than lifestyle. Therefore, it might be useful in changing unhealthy lifestyle and reducing the influence of poor lifestyle on physical, mental and social SHS.

BACKGROUND: TP53 is a crucial tumor suppressor gene. However, the mutation pattern of TP53 in Chinese patients with breast cancer has not yet been determined. METHODS: A total of 411 untreated patients with invasive breast cancer diagnosed at Guangdong Provincial People's Hospital (GDPH) between June 2017 to September 2018 were recruited into the study. Mutational alterations in TP53 were detected and correlations between TP53 mutations and clinicopathological features analyzed. Comparative analysis of the data in the GDPH cohort with those in the METABRIC cohort were carried out. RESULTS: A significantly higher rate of TP53 mutations was detected in the GDPH cohort (51.3%) compared with the METABRIC cohort (34.4%) (P < 0.01). In the GDPH cohort, 77.8% of the mutations were located in the conserved areas across exons 5-8 of TP53; among these, 112 were identified as missense mutations and mainly clustered in the DNA-binding region. R273C/H (n = 11) and R248Q/W (n = 10) were two of the most common mutation sites of TP53 detected in the cohort of GDPH patients. Logistic regression multivariate analysis showed that histological grade III, ki-67 > = 25%, HR- and Her2+ in breast cancer had higher mutation probability of TP53 (P < 0.001 in the GDPH cohort). Furthermore, receiver operating characteristic (ROC) model combining molecular typing and Ki-67 was established to predict the mutation of TP53, and the AUC was 0.846. CONCLUSIONS: A significantly higher rate of TP53 mutation was detected in the Chinese cohort compared with the METABRIC. Correlation analysis revealed a significant association of TP53 mutation with HR- and HER2+, higher Ki-67 and histological grade in breast cancer patients.

BACKGROUND: Association of cardiovascular disease (CVD) or depression and memory has been studied. But hardly any studies on the association of coexistence of CVD and depression and memory. METHODS: This is a prospective cohort study of a nationally representative sample of 12,272 adults aged 45 years and more who participated in the China health and retirement longitudinal study 2011 to 2015. All variables were acquired by self-reporting questions. The associations between coexistence of CVD and depression with memory related disease (MRD) were investigated by using Cox proportional hazards regression models. RESULTS: Among the 12,272 participants (mean age 65.69 years; 46.8% male) in this study, 56.9% no CVD or depression and 6.7% coexistence of CVD and depression. After adjustment for age, sex, marriage, living place, registered permanent residence, education level, smoking status, alcoholic intake, sleep status, nap status, social communication, health before 15 years, life satisfaction, cognitive function, and 11 chronic diseases risk factors, depression alone was significantly high risk for MRD (HR:1.64; 95% CI: 1.09-2.49); coexistence of CVD and depression increased the risk for MRD significantly higher (HR: 4.72; 95%CI: 2.91-7.64). LIMITATIONS: Diseases were all self-reported and we couldn't adjust for all the potential confounders, which might be prone to information error and residual confounding. CONCLUSIONS: In a nationally representative cohort with median 4 years of follow-up, depression alone and co-existence of depression and CVD could significantly increase the risk of MRD. Our study supports the idea of prevention of memory disease from a psycho-cardiology aspect.

BACKGROUND: Total hip arthroplasty is the most common orthopaedic procedure for the end-stage hip diseases. Periprosthetic bone loss is closely related to the increased risk of implant loosening and periprosthetic fractures, but the predictive value of periprosthetic bone mineral density (BMD) measured immediately after surgery has not yet been investigated. METHODS: From April 2015 to October 2017, 64 patients with femoral neck fracture, hip osteoarthritis, femoral head necrosis, or developmental dysplasia of the hip underwent unilateral total hip arthroplasty. Demographic data, bone mineral density of the hip and spine, periprosthetic BMD of 7 Gruen zones, and radiographic parameters measured preoperatively, 1 week, 3 months, and 12 months after surgery were collected. A p value < 0.05 was considered to be statistically significant. RESULTS: Significant decreases of the periprosthetic BMD were found in Gruen zone 1 (- 8.0%; p < 0.05), Gruen zone 2 (- 6.3%; p < 0.05), Gruen zone 7 (- 8.6%; p < 0.05), and total Gruen zone (- 4.7%; p < 0.05) in the first postoperative year, compared with the values measured 1 week after surgery. The relationship between the preoperative BMD of the hip/spine and the BMD of Gruen zone 1 and Gruen zone 7 measured 1 week after surgery did not reach statistical significance. The multiple linear regression analysis illustrated that the bone loss in Gruen zone 7 at the end of the follow-up period was negatively affected (ß = - 0.703) by the BMD of Gruen zone 7 measured 1 week after surgery, with a R2 of 0.486 (p < 0.05). Similar results were also found in Gruen zone 1 (ß = - 0.448, R2 = 0.186; p < 0.05). CONCLUSION: There were marked decreases in periprosthetic BMD of the proximal femur in the first postoperative year. The predictive values of preoperative BMD of hip and spine on periprosthetic bone loss after THA were limited. Higher periprosthetic BMD measured in immediate postoperative period may not guarantee less periprosthetic bone loss in the proximal femur after cementless THA.
RESUMO
Purpose: Retinal vein occlusion is associated with an increased risk of cardiovascular diseases. Anti-vascular endothelial growth factor has been widely used as a treatment option. However, the systemic safety of intravitreal anti-vascular endothelial growth factor for retinal vein occlusion patients is still unclear.Materials and Methods: A meta-analysis was conducted to investigate all randomized controlled trials published up to February 2019 of retinal vein occlusion patients who received intravitreal anti-vascular endothelial growth factor vs. control treatments. Fixed effect models were used and results were reported as odds ratios and 95% confidence intervals.Results: Eight trials that evaluated 2320 patients were retrieved. Anti-vascular endothelial growth factor did not significantly increase the risks of cardiovascular events (odds ratio,1.54; 95% confidence interval, 0.66-3.57), hypertension (odds ratio, 0.92; 95% confidence interval, 0.63-1.33), or heart rate disorders (odds ratio,1.53; 95% confidence interval, 0.37-6.28) when compared with control treatment. Subgroup analyses did not show a significant increase of cardiovascular events in aflibercept (odds ratio,1.96; 95% confidence interval, 0.44-8.81) vs. ranibizumab trials (odds ratio, 1.47; 95% confidence interval, 0.54-4.02); 0.5 mg ranibizumab trials (odds ratio, 1.73; 95% confidence interval, 0.61-4.96) vs. 0.3 mg ranibizumab trials (odds ratio, 0.70; 95% confidence interval, 0.14-3.59); nor branch retinal vein occlusion (odds ratio, 1.32; 95% confidence interval, 0.40-4.33) vs. central retinal vein occlusion trials (odds ratio, 1.93; 95% confidence interval, 0.59-6.29).Conclusions: Intravitreal administration of anti-vascular endothelial growth factor did not significantly increase the risks of cardiovascular events, hypertension or heart rate disorders in retinal vein occlusion patients.

After adjustment for age, sex, marriage, living place, registered permanent residence, education level, smoking status, alcoholic intake, sleep status, nap status, social communication, health before 15 years, life satisfaction, cognitive function, and 11 chronic diseases risk factors, depression alone was significantly high risk for MRD (HR:1.64; 95% CI: 1.09-2.49); coexistence of CVD and depression increased the risk for MRD significantly higher (HR: 4.72; 95%CI: 2.91-7.64). LIMITATIONS: Diseases were all self-reported and we couldn't adjust for all the potential confounders, which might be prone to information error and residual confounding. CONCLUSIONS: In a nationally representative cohort with median 4 years of follow-up, depression alone and coexistence of depression and CVD could significantly increase the risk of MRD. Our study supports the idea of prevention of memory disease from a psycho-cardiology aspect.

OBJECTIVE: To investigate the influence of preoperative osteopenia/osteoporosis on periprosthetic bone loss after total hip arthroplasty (THA) and the efficiency of zoledronate (ZOL) treatment in periprosthetic bone preservation. METHODS: This multicenter, prospective cohort study was conducted in four centers between April 2015 and October 2017. Patients were assigned to Normal BMD, Osteopenia, and Osteoporosis+ZOL groups. Patients with osteopenia received daily oral calcium (600 mg/d) and vitamin D (0.5 µg/d), while patients in the Osteoporosis+ZOL group received additional ZOL annually (5 mg/year). Periprosthetic bone mineral density (BMD) in seven Gruen zones, radiographic parameters, Harris hip score, EuroQol 5-Dimensions (EQ-5D) score, and BMD in hip and spine were measured within 7 days, 3 months, 12 months postoperation and annually thereafter. RESULTS: A total of 266 patients were enrolled, while 81 patients that completed the first year follow-up were involved in the statistical analysis. The mean follow-up time was 1.3 years. There were significant decreases of mean BMD in total Gruen zones (-4.55%, P < 0.05) and Gruen zone 1 (-10.22%, P < 0.01) in patients with osteopenia during the first postoperative year. Patients in the Osteoporosis+ZOL group experienced a marked increase in BMD in Gruen zone 1 (+16%) at the first postoperative year, which had a significant difference when compared with the Normal BMD group (P < 0.05) and the Osteopenia Group (P < 0.001). Low preoperative BMD in hip and spine was predictive of bone loss in Gruen zone 1 at 12 months after THA in patients with normal BMD (R2 = 0.40, P < 0.05). CONCLUSIONS: Patients with osteopenia are prone to higher bone loss in the proximal femur after cementless total hip arthroplasty (THA). ZOL, not solely calcium and vitamin D, could prevent the accelerated periprosthetic bone loss after THA in patients with osteopenia and osteoporosis.

BACKGROUND: Hierarchical medical systems are common in developed countries, but it's not optimistic in China. This study aimed to identify the factors affecting healthcare-seeking behavior among pregnant women in Guangdong, China. METHODS: We conducted a cross-sectional, observational survey, developed using the Andersen's behavioral model. Pregnant women were randomly selected using a two-stage, stratified, random sampling method from hospitals in Guangdong, China. A multinomial logistic regression was used to identify statistically significant variables from aspect of environmental, demographic and pregnancy characteristics associated with pregnant women seeking healthcare at primary, secondary or tertiary hospitals. RESULTS: A total of 1393 pregnant women returned the survey after attending 1 of 12 hospitals within 4 cities of the Guangdong province: 537 (38.5%) of the respondents attended a primary hospital, 437 (31.4%) a secondary hospital, and 419 (30.1%) a tertiary hospital. Women attending primary hospitals were more likely to live closer to the hospital, live rurally, and be educated to a lower level. Several factors were significantly associated with attendance at a secondary vs a primary hospital: the woman's perceived necessity to seek maternal healthcare (OR 1.73, 95% CI [1.1,2.74]), the woman's choice of delivery hospital (OR 1.45, 95% CI [1.01,2.07]), or urban living (OR 1.39, 95% CI [1.03,1.88]). Characteristics associated with attendance at a tertiary vs a primary hospital were: a history of pregnancy complications (OR 2.35, 95% CI [1.43,3.86]), travel to the hospital by public transport/taxi (OR 2.09/2.67, 95% CI [1.35,3.22]/ [1.45,4.92]), urban living (OR 1.58, 95% CI [1.14,2.18]), or a planned current pregnancy (OR 1.53, 95% CI [1.07,2.19]). CONCLUSION: Medical needs and convenience both play a role in the choice of hospital for antenatal care, and impact on equity utilization of health services. Pregnant women without risk factors and with higher levels of education should be a target population for guiding to choose a more proper level of hospital.

OBJECTIVE: To explore the direct relationship between personality (PN) and sub-health status (SHS) and their indirect association mediated by frustration quotient (FQ) and stress event (SE). METHODS: A multiple-stage stratified sampling method was used to choose the participants, and a total of 4517 eligible urban residents were selected.ANCOVA was used to analyze the independent association between personality and SHS after adjusting the demographic characteristics and lifestyle.A structural equation model was used to analyze the associations among personality, FQ, SE and SHS.Bootstrap method was used to test the direct and indirect association between personality and SHS. RESULTS: Personality was independently associated with total sub-health (F=75.913, P < 0.001), physical sub-health (F=23.618, P < 0.001), mental sub-health (F=101.993, P < 0.001) and social sub-health (F=48.757, P < 0.001).The urban residents with the personalities characterized by anger suppression, anxiety and irritability, and impatience and competitiveness had significantly lower health scores than those with a mature and steady personality (P < 0.05).Personality was associated with FQ and SE, and the indirect association between personality and physical sub-health was mainly mediated by FQ and SE (ß=-0.110).Personality showed more a direct association (ß=-0.172) with mental sub-health and a slightly less indirect association (ß=-0.126) with mental sub-health.Personality showed a more indirect association (ß=-0.113) with social SHS and slightly less direct association (ß=-0.082) with social sub-health. CONCLUSIONS: A mature and steady personality may help to promote the general health level, while the personalities of anger suppression, anxiety and irritability, impatience and competitiveness can be associated with the occurrence of sub-health.Building a mature and steady personality has positive effects on the health in general of an individual.

OBJECTIVE: To establish the norms of Sub-Health Measurement Scale (SHMS V1.0) for Chinese urban residents. METHODS: Using a multistage stratified sampling method, we conducted a large-scale epidemiological investigation among 15 066 urban residents sampled from 6 regions in China, including Tianjin City (north China), Guangdong Province (south China), Anhui Province (central south China), Sichuan Province (southwest China), Lanzhou City (northwest China) and Harbin City (northeast China). The mean, percentile and threshold norms were established based on the characteristics of SHMS V1.0 scores for Chinese urban residents. RESULTS: The mean and percentile norms of total, physical, mental and social sub-health of Chinese urban residents were established according to gender and different age groups (14-19, 20-29, 30-49, 50-64 and ≥65 years). The threshold norms of SHMS V1.0 divided 5 health states, namely disease, severe sub-health, moderate subhealth, mild sub-health and healthy states according to the Mean±SD and Mean±0.5SD of the converted scores. CONCLUSIONS: The norms of Sub-Health Measurement Scale (SHMS V1.0) for Chinese urban residents were established, which provides a reference for rapid screening and diagnosis of sub-health status in Chinese urban residents and facilitates further study of the prevalence and contributing factors of sub-health.

A large proportion of patients with coronary artery disease (CAD) suffer from depression or anxiety symptoms and this is associated with increased mortality [1]. This double-blinded, randomized, placebo-controlled, clinical trial (ChiCTR-IPR-17010940) aimed to explore whether Xinkeshu tablets can reduce anxiety or depressive symptoms in CAD patients and how this is related to the concentration of plasma cytokines. Sixty patients with CAD anda Hospital Anxiety and Depression Scale (HADS-a/HADS-d) score of ≥8 were treated with Xinkeshu tablets or placebo for 12 weeks following percutaneous revascularization. Depressive/anxiety symptoms and the levels of 440 peripheral blood cytokines were evaluated at baseline and after 12 weeks treatment. Results showed significantly lower (P < 0.05) HADS-a/HADS-d and PHQ-9 scores in CAD patients treated with Xinkeshu tablets than in those who received placebo. These improvements were associated with changes in certain peripheral blood cytokines; most notably trappin-2, adiponectin, interleukin 1ß (IL-1ß), thrombopoietin, activated leukocyte cell adhesion molecule (ALCAM), neurotrophin-3 (NT-3), and transferrin. A significant correlation between anxiety/depression symptoms and trappin-2, NT-3, transferrin, and ALCAM (p < 0.05) were observed in an independent cohort of patients with CAD. These findings were in-keeping with the anti-depressive effects of Xinkeshu tablets. This trial demonstrates that Xinkeshu tablets can improve anxiety and depression symtoms effectively address in patients with coronary heart disease possibly through increasing the blood ratio of anti-inflammatory:pro-inflammatory cytokines.
