RESUMEN
The Beijing Healthy Aging Cohort Study (BHACS) was established to supplement the limited data of a large representative cohort of older people based on the general population and was designed to evaluate the prevalence, incidence, and natural history of cognitive decline, functional disability, and conventional vascular risk factors. The aim was to determine the evolution of these conditions by estimating the rates and determinants of progression and regression to adverse outcomes, including dementia, cardiovascular events, cancer, and all-cause death. It can therefore provide evidence to help policy makers develop better policies to promote healthy aging in China. BHACS consisted of three cohorts (BLSA, CCHS-Beijing, and BECHCS) in Beijing with a total population of 11 235 (6281 in urban and 4954 in rural areas) and an age range of 55 years or older (55-101 years) with a mean age of 70.35 ± 7.71 years (70.69 ± 7.62 years in urban and 69.92 ± 7.80 years in rural areas). BHACS-BLSA conducted the baseline survey in 2009 with a multistage stratification-random clustering procedure for people aged 55 years or older; BHACS-CCHS-Beijing conducted the baseline survey in 2013-2015 with a stratified multistage cluster random sampling method for people aged 55 years or older; and BHACS-BECHCS conducted the baseline survey in 2010-2014 with two-stage cluster random sampling method for people aged 60 years or older. Data were collected through questionnaires, physical measurements, and laboratory analyses. Topics covered by BHACS include a wide range of physical and mental health indicators, lifestyles and personal, family, and socio-economic determinants of health. There are no immediate plans to make the cohort data freely available to the public, but specific proposals for further collaboration are welcome.

OBJECTIVE: This study, based on the China Hainan Centenarians Cohort Study (CHCCS), aims to comprehensively describe the characteristic of daytime, night and total sleep duration, sleep quality and different sleep mode of Hainan centenarians and their associations with activity of daily living (ADL) functions. METHOD: The baseline data of CHCCS was used. ADL function was evaluated the Bathel index, sleep quality was evaluated by Pittsburgh sleep quality index (PSQI), sleep status including daytime, night and total sleep duration as well as sleep quality and sleep mode. Multivariate logistic regression model was used to explore the association between sleep status and ADL disability and ADL moderate & severe disability. RESULTS: A total of 994 centenarians were included in this study with the age range 100-116 years old. Compared with the centenarians who sleep 6-9 h at night and < 2 h in the daytime, the adjusted OR between sleep > 9 h at night and sleep ≥ 2 h in the daytime and ADL disability was 2.93 (95% CI: 1.02-8.44), and adjusted OR of ADL moderate & severe disability was 2.75 (95% CI: 1.56-4.83). Compared with centenarians who sleep for 7-9 h and have good sleep quality, centenarians who sleep for > 9 h and have poor sleep quality have an increased risk of ADL moderate & severe disability (OR = 3.72, 95% CI: 1.54-9.00). CONCLUSION: Relation between sleep duration and ADL disability was more significant compared with sleep quality in Hainan centenarians. Poor sleep quality can aggravate the relationship between sleep duration and ADL moderate & severe disability.

BACKGROUND: Cardiovascular disease has become the leading cause of death worldwide, but there is a lack of data on whether cardiovascular health (CVH) is associated with elderly mortality in China. We investigated the relationship between the ideal CVH score of Chinese elderly and the all-cause mortality. METHODS: The Beijing Elderly Comprehensive Health Cohort Study included a total of 4,499 participants aged 60 years and above. The CVH metric was calculated at baseline and had a score ranging from 0 to 12. The relationship of CVH metrics with all-cause mortality was investigated using Cox proportional hazard regression analysis. The robustness of results was tested using subgroup and sensitivity analysis. RESULTS: The median CVH score among participants was 8.00 (2.00), with only 8.0% scoring 11-12 points. 667 deaths were observed during an average follow-up time of 8.2 years. Participants with a CVH score of 11-12 had a decreased risk of all-cause mortality when compared to those with a CVH score of 0-4(HR = 0.584, 95% CI: 0.373-0.913). Participants had a 7.5% lower risk of all-cause death with each unit higher CVH score (HR = 0.925, 95%CI: 0.885-0.967) with a linearly decreasing trend (P nonlinear = 0.575). The relationships were greater in younger elderly people and stroke patients (P interaction = 0.011 and 0.037. respectively). The consistency of significant trends in sensitivity analysis shows the robustness of association (P trend < 0.001). CONCLUSIONS: Among the Chinese elderly, there was a linear relationship between improving CVH scores and a lower risk of all-cause mortality. Because of the enormous benefits brought by one point, strategies are essential for improving cardiovascular health attainment. TRIAL REGISTRATION: This study was registered at China Clinical Trial Registration Center (ChiCTR2100049866).

OBJECTIVES: This study aimed to analyze the association between sleep quality, sleep duration, and cognitive functions among centenarians. METHODS: The baseline data of the China Hainan Centenarians Cohort Study served as the foundation for this study. Logistic regression was utilized to demonstrate the relationship between sleep status and cognitive impairment. Moreover, a canonical correlation analysis was performed to analyze the correlation between these variables. RESULTS: A total of 994 centenarians were included. After adjustment, poor sleep quality centenarians had an odds ratio of 1.77 (95% confidence interval [CI]: 1.00-3.09) for cognitive impairment when compared to centenarians with normal sleep quality. Centenarians who slept for more than 9 hr had a stronger association with severe cognitive impairment, indicated by an odds ratio of 1.41 (95% CI: 1.02-1.96), compared to those who slept for 7-9 hr. Additionally, the canonical correlation analysis results revealed that the linear combination of sleep quality V1, primarily determined by sleep latency, daytime dysfunction, and subjective sleep quality, was associated with cognitive function; the linear combination of cognitive function W1, mainly determined by orientation, attention and calculation, and memory. DISCUSSION: There exists a correlation between poor sleep quality and cognitive impairment in centenarians, as well as a correlation between sleep duration >9 hr at night and severe cognitive impairment. The primary cognitive domains associated with sleep quality are orientation, calculation, and memory. It is imperative to monitor and safeguard the cognitive functions linked to poor sleep quality in the older individuals, with attention to orientation, calculation, and memory.

BACKGROUND: Cardiometabolic diseases (CMDs) increases the risk of cognitive decline, but the extent to which this can be offset by adherence to an active integrated lifestyle is unknown. METHODS: This prospective study used the baseline and 2-year follow-up data of 2537 dementia-free elderly ≥60 from PINDEC Project. Lifestyle factors (including physical exercise, social interaction, leisure activities, sleep quality, smoking, and alcohol consumption) were collected and the integrated score was calculated. Participants were divided into three groups based on integrated score tertiles (inactive, ≤3 score; intermediate, 4 score; and active, ≥5). Logistic regression was used in data analysis. RESULTS: 35.2 % participants had 5-6 healthy components, while only 5.4 % had all 6 healthy lifestyles. The multiadjusted odds ratios (ORs, 95 % confidence interval) of early cognitive decline was 1.223 (0.799-1.871) and 1.832 (1.140-2.943) for participants with only one CMD and any two or more CMDs, respectively. An inverse dose-response relationship was found between lifestyle scores and early cognitive decline (Ptrend = 0.017). In participants with active lifestyle, the OR for early cognitive decline comparing the CMDs status of any two or more CMDs vs. CMDs-free was 0.778 (95%CI: 0.302-2.007). Participants with inactive lifestyle and any two or more CMDs had a near 3.4-fold increased risk of early cognitive decline than those without CMDs who had intermediate to active lifestyle (OR = 3.422, 95%CI: 1.764-6.638). LIMITATIONS: Our research lacks information about nutrition. CONCLUSIONS: A dose-response relationship exists between CMDs status and risk of early cognitive decline. However, adherence to an active integrated lifestyle may mitigate this risk.

OBJECTIVE: To explore the factors affecting short-term prognosis of circulatory failure patients undergoing venoarterial extracorporeal membrane oxygenation (VA-ECMO) treatment. METHODS: A total of 136 patients undergoing VA-ECMO were enrolled in this study and subsequently divided into the death group (n=35) and the survival group (n=101) based on whether death occurred during hospitalisation. Extracorporeal membrane oxygenation (ECMO) running time, length of intensive care unit stay, length of hospital stay, costs, and ECMO complications were then compared between the two groups. RESULTS: The average age of all patients undergoing ECMO was 47.64±16.78 years (53.2±16.20 years in the death group and 45.713±16.62 years in the survival group) (P=0.022). Patients in the survival group exhibited a clear downward trend in lactic acid value following ECMO treatment compared to those in the death group. Total hospitalisation stay was longer in the survival group (35 days) than in the death group (15.5 days) (P<0.001). In the analysis of ECMO complications, the incidence of neurological complications, renal failure, limb complications, and infection were higher in the death group than in the survival group (P<0.05 for all). Specifically, as a risk factor for patient survival and discharge, the occurrence of infection will lead to increased hospitalisation stays and costs (P<0.05 for both). CONCLUSION: Complications such as kidney failure and infection are associated with in-hospital death, and ECMO-related complications should be actively prevented to improve the survival rate of VA-ECMO treatment.

OBJECTIVE: The objective of this study is to analyze the association between sleep quality, sleep duration, sleep patterns, and depressive states among centenarians due to the crucial impact of depression on the well-being of elderly individuals, particularly the oldest. Recognizing easily identifiable manifestations and risk factors is essential since the onset of depressive states tends to be insidious. METHODS: The baseline data from the China Hainan Centenarians Cohort Study (CHCCS) served as the basis for this study. Questionnaire surveys were conducted to obtain research indicators, with depressive states evaluated using the GDS-15 scale and sleep quality evaluated using the Pittsburgh Sleep Quality Index (PSQI). Logistic regression was employed to describe the association between sleep status and depressive states. RESULTS: A total of 994 centenarians, with an age range of 100-116 years and a mean age of 102.77 ± 2.75 years, were included in this study. Among these participants, 815 were female, accounting for 82.0 %. After adjustment, the odds ratio (OR) for the association between poor sleep quality and depressive states was 2.07 (95 % CI: 1.54-2.77) compared to those with normal sleep quality. Additionally, there were associations between depressive states and both nighttime sleep duration and total sleep duration. After adjustment, the strongest association between depressive state and sleep patterns was found for those who had >9 h of nighttime sleep and ≥2 h of daytime sleep (OR = 1.80, 95%CI: 1.02-3.16). Moreover, compared to centenarians with 7-9 h of sleep duration and good sleep quality, the highest odds ratio (OR = 3.44, 95%CI: 2.18-5.43) for the association between depressive states and sleep duration ≤7 h and poor sleep quality was observed. CONCLUSION: The findings of this study indicate that there is an association between poor sleep quality and depressive states in centenarians. Furthermore, both sleep quality and long/short total sleep duration are associated with depressive states in this population. Therefore, special attention should be given to the psychological state of elderly individuals with short sleep duration and poor sleep quality in order to prevent depression and minimize its negative impact on their overall health.

Objective: To investigate the preventive effect of distal perfusion catheters (DPCs) on vascular complications in patients undergoing venous artery extracorporeal membrane oxygenation (VA-ECMO). Methods: Patients who underwent VA-ECMO through a femoral approach in our hospital were included in this study, and they were divided into two groups according to their use of DPC. Clinical indicators were compared between the two groups, including the ECMO running time, intensive care unit (ICU) time, length of hospital stay, ECMO auxiliary results, the incidence of limb ischemia and vascular complications. Results: In total, 250 patients were included in this study, including the DPC group (age: 48 [32-62] years old, 58.4% male, n = 125) and the non-DPC group (age: 51 [36-63] years old, 65.6% male, n = 125). The DPC group was less likely to have limb complications than the non-DPC group (6.4% vs 17.6%, P = 0.006), mainly resulting from distal ischemia (4.0% vs 15.2%, P = 0.003) and necrosis (1.6% vs 9.6%, P = 0.006). The ECMO duration had a median of 92.3 (75.7-109) h in the DPC group and 71.2 (59.4-82.8) h in the DPC group, with a difference close to the statistical threshold (P = 0.054). There was no significant difference in ICU time or length of hospital stay between the two groups. The multivariate analysis showed that the DPC implantation was negatively associated with limb complications (odds ratio: 0.265, 95% confidence interval: 0.107-0.657, P = 0.004) after adjustment for confounding factors. Conclusion: Distal perfusion catheter placement might be associated with a decreased risk of vascular complications and limb ischemia in patients undergoing femoral VA-ECMO cannulation. Further randomised studies are still needed to verify its benefit on clinical outcomes.
RESUMEN
BACKGROUND: Although hypoalbuminemia was associated with high risk of mortality in community-dwelling older adults, as well as in the hospitalized older adults, little is known among centenarians. And there are limited data on whether having cardiometabolic diseases (CMDs) is associated with additive effects. METHODS: Baseline examinations including a determination of albumin levels were performed in 1002 Chinese centenarians from January 2014 through to December 2016, and the survival status was subsequently ascertained until 31 May 2021. Cox proportional risk model was performed to assess the risk of all-cause mortality associated with albumin levels and hypoalbuminemia combined with CMDs. RESULTS: Of 1002 participants included in the analysis, the mean level of albumin was 38.5 g/L (± standard deviation, 4.0 g/L), and 174 (17.4%) had hypoalbuminemia (albumin < 35 g/L). The multivariable analyses showed that albumin level was negatively associated with all-cause mortality (Ptrend < 0.05). Compared to normoalbuminemia, hypoalbuminemia was associated with an increased mortality risk in the overall participants (hazard ratio [HR]: 1.55, 95% confidence interval [CI]: 1.22-1.97). Furthermore, the HR (95% CI) of hypoalbuminemia combined with multiple CMDs was 2.15 (1.14-4.07). There was evidence of an additive deleterious dose effect of an increasing number of CMDs (Ptrend = 0.001). CONCLUSIONS: Hypoalbuminemia is associated with an increased risk of all-cause mortality in Chinese centenarians, and this risk is more pronounced among centenarians with multiple cardiometabolic diseases. Our findings suggest that older adults with hypoalbuminemia, especially comorbid multiple CMDs warrant early identification and management.
RESUMEN
Background: As the focal point of epidemic prevention and control, the mental health of COVID-19 patients cannot be ignored. Online Mindfulness-Based Stress Reduction (MBSR) allows for the provision of conveniently accessible, effective and low-cost interventions on a large scale. We aim to evaluate the effectiveness of an online MBSR intervention in alleviating anxiety and depression among asymptomatic/mild patients limited by COVID-19-related restrictions. Methods: Fifty-eight patients treated in Sanya Fangcang hospital were randomly allocated to either to the experimental group (n = 29) following daily, for 5 days, an online-based mindfulness intervention or to the control group (n = 29). Patients from both groups underwent online questionnaires including assessment of anxiety and depression status at pre- and post-tests using Self-rating Anxiety Scale and Self-Rating Depression Scale. Results: After the online-based MBSR program, the anxiety and depression scores of the patients in the MBSR group decreased significantly in comparison to the scores of those in the control group (respectively η2 = 0.175, η2 = 0.215, p < 0.001). And the proportion of severe anxiety and depression patients in the MBSR group decreased to 0% which lower than the control group, and the proportion of light anxiety and depression patients was significantly more than that in the control group after the MBSR intervention. Conclusion: The online-based MBSR intervention appears to be an effective way of alleviating anxiety and depression symptoms among COVID-19 patients with associated quarantine in Fangcang hospital. Given the seriousness of mental health threat that could be posed by this ongoing pandemic, our study provides a new idea and method for cost-effective and time-efficient interventions in the future of epidemic prevention and control.
RESUMEN
IMPORTANCE: Little evidence on the association between adiposity measures and all-cause mortality was observed among centenarians, and no targeted development of optimal weight recommendations for them. OBJECTIVE: To comprehensively assess the association between adiposity indices and all-cause mortality among centenarians. DESIGN SETTING, AND PARTICIPANTS: This prospective population-based cohort study included 1002 centenarians registered in 18 counties and cities in Hainan Province from June 2014 to May 2021. The age of participants at baseline was provided by the civil affairs bureau and verified before enrollment. MAIN OUTCOMES AND MEASURES: All-cause mortality was rigorously confirmed as the primary outcome. BMI was calculated by height and weight. BRI was calculated by height and waist circumference. RESULTS: At baseline, the mean (SD) age was 102.8 ± 2.7 years, and 180 participants (18.0%) were men. The median follow-up time was 5.0 (4.8-5.5) years, with 522 deaths. In BMI categories, compared with the lowest group (mean BMI = 14.2 kg/m2), the highest group (mean BMI = 22.2 kg/m2) had lower mortality (hazard ratio [HR], 0.61; 95%CI, 0.47-0.79) (P for trend = 0.001). In BRI categories, compared with the lowest group (mean BRI = 2.3), the highest group (mean BRI = 5.7) had lower mortality (hazard ratio [HR], 0.66; 95%CI, 0.51-0.85) (P for trend = 0.002), and the risk did not decrease after BRI exceeded 3.9 in women. Higher BRI was associated with lower HRs after adjusting for interaction with comorbidities status. E-values analysis suggested robustness to unmeasured confounding. CONCLUSIONS AND RELEVANCE: BMI and BRI were inverse linear associated with mortality risk in the whole population, while BRI was observed to be J-shaped in women. The interaction of lower multiple complication incidence and BRI had a significant effect on the reduced risk of all-cause mortality.

Brain volume decrease in the anterior cingulate cortex (ACC) after lead (Pb) exposure has been linked to persistent impairment of attention behavior. However, the precise structural change and molecular mechanism for the Pb-induced ACC alteration and its contribution to inattention have yet to be fully characterized. The present study determined the role of miRNA regulated synaptic structural and functional impairment in the ACC and its relationship to attention deficit disorder in Pb exposed mice. Results showed that Pb exposure induced presynaptic impairment and structural alterations in the ACC. Furthermore, we screened for critical miRNA targets responsible for the synaptic alteration. We found that miR-130, which regulates presynaptic vesicle releasing protein SNAP-25, was responsible for the presynaptic impairment in the ACC and attention deficits in mice. Blocking miR-130 function reversed the Pb-induced decrease in the expression of its presynaptic target SNAP-25, leading to the redistribution of presynaptic vesicles, as well as improved presynaptic function and attention in Pb exposed mice. We report, for the first time, that miR-130 regulating SNAP-25 mediates Pb-induced presynaptic structural and functional impairment in the ACC along with attention deficit disorder in mice.

OBJECTIVE: To evaluate the associations of lipid indicators and mortality in Beijing Elderly Comprehensive Health Cohort Study. METHODS: A prospective cohort was conducted based on Beijing Elderly Comprehensive Health Cohort Study with 4499 community older adults. After the baseline survey, the last follow-up was March 31, 2021 with an average 8.13 years of follow-up. Cox proportional hazard model was used to estimate the hazard ratios (HR) with 95% CI for cardiovascular disease (CVD) death and all-cause death in associations with baseline lipid indicators. RESULTS: A total of 4499 participants were recruited, and the mean levels of uric acid, body mass index, systolic blood pressure, diastolic blood pressure, fasting plasma glucose, total cholesterol (TC), triglyceride, and low-density lipoprotein cholesterol (LDL-C) showed an upward trend with the increasing remnant cholesterol (RC) quarters (Ptrend < 0.05), while the downward trend was found in high-density lipoprotein cholesterol (HDL-C). During the total 36,596 person-years follow-up, the CVD mortality and all-cause mortality during an average 8.13 years of follow-up was 3.87% (95% CI: 3.30%-4.43%) and 14.83% (95% CI: 13.79%-15.86%) with 174 CVD death participants and 667 all-cause death participants. After adjusting for confounders, the higher level of TC (HR = 0.854, 95% CI: 0.730-0.997), LDL-C (HR = 0.817, 95% CI: 0.680-0.982) and HDL-C (HR = 0.443, 95% CI: 0.271-0.724) were associated with lower risk of CVD death, and the higher level of HDL-C (HR = 0.637, 95% CI: 0.501-0.810) were associated with lower risk of all-cause death. The higher level of RC (HR = 1.276, 95% CI: 1.010-1.613) increase the risk of CVD death. Compared with the normal lipid group, TC ≥ 6.20 mmol/L group and LDL-C ≥ 4.10 mmol/L group were no longer associated with lower risk of CVD death, while RC ≥ 0.80 mmol/L group was still associated with higher risk of CVD death. In normal lipid group, the higher levels of TC, LDL-C and HDL-C were related with lower CVD death. CONCLUSIONS: In community older adults, higher levels of TC and HDL-C were associated with lower CVD mortality in normal lipid reference range. Higher RC was associated with higher CVD mortality, which may be a better lipid indicator for estimating the CVD death risk in older adults.
RESUMEN
BACKGROUND: Gallbladder and biliary tract cancer (GBTC) has greatly damaged the health of patients and is accompanied by a dismal prognosis. The worldwide distribution of GBTC shows extensive variance and the updated data in China is lacking. This study was to determine the current status, trends, and predictions in the burden of GBTC over the past 30 years in China. METHODS: This was a descriptive, epidemiological, secondary analysis of the Global Burden of Disease, Injuries, and Risk Factor Study 2019 data. Data including incidence, prevalence, mortality, and disability-adjusted life years (DALYs) of GBTC in China by year, age, and sex were assessed. Joinpoint regression analysis was conducted to evaluate trends of disease burden due to GBTC from 1990 to 2019. Nordpred age-period-cohort analysis was applied for the projection of mortality and incidence due to GBTC from 2019 to 2044. RESULTS: Nationally, there were 38,634 (95% uncertainty interval [UI]: 27,350-46,512) new cases and 47,278 (95% UI: 32,889-57,229) patients due to GBTC, causing 34,462 (95% UI: 25,220-41,231) deaths, and 763,584 (95% UI: 566,755-920,493) DALYs in 2019. Both cases and rates of burden owing to GBTC were heavier among males and at old age. From 1990 to 2019, the age-standardized rates of incidence, prevalence, mortality, and DALYs of GBTC generally increased from 1990 to 2019, with average annual percentage change at 0.8% (95% confidential interval [CI]: 0.6-1.0%), 1.3% (95% CI: 1.1-1.5%), 0.4% (95% CI: 0.2-0.6%), and 0.2% (95% CI: 0.1-0.4%), respectively. Even though the age-standardized incidence rate and age-standardized mortality rate in both sexes were predicted to decline gradually from 2019 to 2044, the number of new cases and deaths were expected to grow steadily. CONCLUSIONS: GBTC is becoming a major health burden in China, particularly among males and older individuals. Given the aging population and increasing burden, effective strategies and measurements are urged to prevent or reduce the number of new cases and deaths of GBTC.

BACKGROUND: Hypertension is associated with stroke-related mortality. However, the long-term association of blood pressure (BP) and the risk of stroke-related mortality and the influence path of BP on stroke-related death remain unknown. The current study aimed to estimate the long-term causal associations between BP and stroke-related mortality and the potential mediating and moderated mediating model of the associations. METHODS: This is a 45-year follow-up cohort study and a total of 1696 subjects were enrolled in 1976 and 1081 participants died by the latest follow-up in 2020. COX proportional hazard model was used to explore the associations of stroke-related death with baseline systolic blood pressure (SBP)/diastolic blood pressure (DBP) categories and BP changes from 1976 to 1994. The mediating and moderated mediating effects were performed to detect the possible influencing path from BP to stroke-related deaths. E value was calculated in the sensitivity analysis. RESULTS: Among 1696 participants, the average age was 44.38â±â6.10 years, and 1124 were men (66.3%). After a 45-year follow-up, a total of 201 (11.9%) stroke-related deaths occurred. After the adjustment, the COX proportional hazard model showed that among the participants with SBPâ≥â160 mmHg or DBPâ≥â100 mmHg in 1976, the risk of stroke-related death increased by 217.5% (hazard ratio [HR]â=â3.175, 95% confidence interval [CI]: 2.297-4.388), and the adjusted HRs were higher in male participants. Among the participants with hypertension in 1976 and 1994, the risk of stroke-related death increased by 110.4% (HRâ=â2.104, 95% CI: 1.632-2.713), and the adjusted HRs of the BP changes were higher in male participants. Body mass index (BMI) significantly mediated the association of SBP and stroke-related deaths and this mediating effect was moderated by gender. CONCLUSIONS: In a 45-year follow-up, high BP and persistent hypertension are associated with stroke-related death, and these associations were even more pronounced in male participants. The paths of association are mediated by BMI and moderated by gender.

Background: Diabetes mellitus (DM) or cognitive impairment (CI) is known to be strongly associated with mortality. DM commonly coexists with CI and proportionally increases with age. However, little is known about the combined effect of cognitive function and diabetes on mortality. This study aimed to evaluate the combined effects of DM and CI on all-cause and cause-specific mortality in Chinese older adults. Methods: This prospective population-based cohort study was based on the Beijing Elderly Comprehensive Health Cohort Study. A total of 4,499 older adults were included. Cox's proportional hazard models were utilized to calculate the effect of DM and CI on all-cause, cardiovascular disease (CVD) mortality and cancer mortality, and a multiplicative term was introduced to study a potential interaction between DM and CI on outcomes. Results: During a median follow-up of 6.8 years (ranging from 6.6 to 11.7 years), 667 (14.8%) participants died from all causes, 292 from CVD, and 215 from cancer. In the fully adjusted model, participants with coexisting DM and CI had the highest risk of all-cause mortality [hazard ratios (HRs), 3.08; 95% confidence intervals (CIs), 2.30,4.11] and CVD mortality (HRs, 3.85; 95% CIs, 2.60,5.71) compared with individuals with normal cognition and non-DM. We also found a multiplicative interaction between DM and CI in respect to all-cause (HRs, 2.46; 95% CI, 1.87,3.22) and CVD mortality (HRs, 3.15 95% CI, 2.19,4.55). In the diabetic population, CI was associated with an increased risk of all-cause mortality (HRs, 2.09; 95% CIs, 1.51,2.89) and CVD mortality (HRs, 3.16; 95% CIs, 2.02,5.05) compared with the normal cognition group. Restricted cubic spline revealed a linear inverse association between Mini-Mental State Examination (MMSE) score and all-cause, CVD mortality in the total sample and participants without diabetes. However, a nearly reverse J association was observed between MMSE and mortality from all causes and CVD in the diabetes group. Conclusion: The findings highlighted that cognitive impairment concomitant with diabetes further increases the risk of mortality. In addition to strengthening routine screening of cognitive functioning in older adults with early-stage diabetes, more extensive assessment of prognostic risks has high clinical value for developing comprehensive treatment plans.

Objective: Cognitive impairment (CI) has been demonstrated as a useful proxy measure of mortality in Western populations. However, the predictive value of CI in Chinese populations is unknown. We aimed to explore whether CI is independently associated with increased long-term all-cause and cardiovascular disease (CVD) mortality in Chinese older adults and the association of performance in specific MMSE sub-domains to subsequent mortality. Methods and results: A total of 4,499 older adults [mean (SD) age, 70.3(6.7) years] who received a sample investigation from 2011 to 2014 were followed up till 2021 for mortality. The Mini-Mental State Examination was used to assess cognitive function, and Cox's proportional hazard models were used to evaluate the effects of cognitive function on the risk of all-cause and CVD mortality. Demographic characteristics, lifestyle, and health status were included as covariates. During a 10-year follow-up, a total of 667 (14.8%) died. In the fully adjusted model, compared with cognitively normal participants with CI had a 1.33-fold [HR, 1.33; (95% CI, 1.10-1.61)] greater risk of all-cause mortality and a 1.45-fold [HR, 1.45; (95% CIs, 1.11-1.92)] greater risk of CVD mortality. After a similar multivariable adjustment, a per-SD increase in MMSE scores was associated with a reduced risk of all-cause mortality [HR, 0.85; (95% CI, 0.78-0.93)] and CVD mortality [HR, 0.74; (95% CI, 0.65-0.84)]. In the unadjusted model, MMSE sub-domains (apart from immediate recall) were associated with mortality. But only orientation and calculation and attention were still independently associated with all-cause and CVD mortality in a multivariable model. Conclusion: These findings confirmed that CI is a marker of all-cause and CVD mortality risk in Chinese older adults, independently of other commonly assessed risk factors, and some sub-domains of the MMSE may have stronger associations with mortality. Further research is needed to identify the mechanisms underlying the observed associations.

Aim: One of the most common laboratory findings in COVID-19 patients has been observed to be hypercoagulability with elevated D-dimer levels. An activation of thrombosis may be generated by hyperglycemia. We aimed to explore the association between D-dimer and in-hospital outcomes, and evaluate the synergistic effect between elevated D-dimer and hyperglycemia on COVID-19 prognosis. Methods: A retrospective cohort study was undertaken with 2467 COVID-19 inpatients. D-dimer and fasting blood glucose (FBG) on admission and adverse in-hospital outcomes (events of death and aggravated severity) were collected. Cox proportional risk model was performed to assess the association of D-dimer and adverse in-hospital outcomes, and the combined effects of D-dimer and FBG. Results: Among these COVID-19 patients, 1100 (44.6%) patients had high D-dimer (≥0.50 mg/L). Patients with high D-dimer were older, with higher FBG (≥7.00 mmol/L), and had significantly higher adjusted risk of adverse in-hospital outcomes when comparing with those who with D-dimer<0.50 mg/L (hazard ratio, 2.73; 95% confidence interval, 1.46-5.11). Moreover, patients with high FBG and D-dimer levels had an increasing risk (hazard ratio, 5.72; 95% confidence interval: 2.65-12.34) than those with normal FBG and D-dimer. Conclusion: Risk of adverse in-hospital outcomes is higher among patients with high D-dimer levels. Additionally, this study found for the first time that elevated D-dimer and hyperglycemia had a synergistic effect on COVID-19 prognosis, and this risk was independent of diabetes history.
RESUMEN
BACKGROUND: Multimorbidity presents an enormous problem to societal and healthcare utilization under the context of aging population in low- and middle-income countries (LMICs). Currently, systematic studies on the profile of multimorbidity and its characteristics among Chinese elderly are lacking. We described the temporal and spatial trends in the prevalence of multimorbidity and explored chronological changes of comorbidity patterns in a large elderly population survey. METHODS: Data were extracted from the Chinese Longitudinal Healthy Longevity Study (CLHLS) conducted between 1998 and 2018 in a random selection of half of the counties and city districts. All the elderly aged 65 and older were included in the survey of eight waves. We used 13 investigated chronic diseases to measure the prevalence of multimorbidity by means of geography, subpopulation, and chronological changes. The patterns of multimorbidity were assessed by computing the value of relative risk (RR indicates the likelihood of certain diseases to be associated with multimorbidity) and the observed-to-expected ratio (O/E indicates the likelihood of the coexistence of a multimorbidity combination). RESULTS: From 1998 to 2018, the prevalence of multimorbidity went from 15.60 to 30.76%, increasing in the fluctuation across the survey of eight waves (p for trend = 0.020). Increasing trends were observed similarly in a different gender group (p male = 0.009; p female = 0.004) and age groups among female participants (p ~80 = 0.009; p 81-90 = 0.004; p 91-100 = 0.035; p 101~ = 0.018). The gap in the prevalence of multimorbidity between the north and the south was getting narrow across the survey of eight waves. Hypertension was the highest prevalent chronic condition while diabetes was most likely to coexist with other chronic conditions in the CLHLS survey. The most frequently occurring clusters were hypertension and heart disease, hypertension and cataract, and hypertension and chronic lung disease. And, the cancer, TB, and Parkinson's disease cluster took the domination of O/E rankings over time, which had a higher probability of coexistence in all the multimorbidity combinations. CONCLUSIONS: The prevalence of multimorbidity has been increasing nationwide, and more attention should be paid to a rapid growth in the southern part of China. It demands the effective diagnosis and treatment adopted to the highly prevalent comorbidities, and strategies and measures were adjusted to strongly relevant clusters.
RESUMEN
ABSTRACT Objective: To explore the factors affecting short-term prognosis of circulatory failure patients undergoing venoarterial extracorporeal membrane oxygenation (VA-ECMO) treatment. Methods: A total of 136 patients undergoing VA-ECMO were enrolled in this study and subsequently divided into the death group (n=35) and the survival group (n=101) based on whether death occurred during hospitalisation. Extracorporeal membrane oxygenation (ECMO) running time, length of intensive care unit stay, length of hospital stay, costs, and ECMO complications were then compared between the two groups. Results: The average age of all patients undergoing ECMO was 47.64±16.78 years (53.2±16.20 years in the death group and 45.713±16.62 years in the survival group) (P=0.022). Patients in the survival group exhibited a clear downward trend in lactic acid value following ECMO treatment compared to those in the death group. Total hospitalisation stay was longer in the survival group (35 days) than in the death group (15.5 days) (P<0.001). In the analysis of ECMO complications, the incidence of neurological complications, renal failure, limb complications, and infection were higher in the death group than in the survival group (P<0.05 for all). Specifically, as a risk factor for patient survival and discharge, the occurrence of infection will lead to increased hospitalisation stays and costs (P<0.05 for both). Conclusion: Complications such as kidney failure and infection are associated with in-hospital death, and ECMO-related complications should be actively prevented to improve the survival rate of VA-ECMO treatment.
