    • Relationship between subclinical hyperthyroidism and the incidence of coronary heart disease: a meta-analysis

      Objectives To assess the relationship between subclinical hyperthyroidism and the incidence of coronary heart disease (CHD). Methods PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, VIP, WanFang Data and CBM databases were searched for studies on the relationship between subclinical hyperthyroidism and the incidence of CHD from inception to October 2016. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 and Stata 12.0 software. Results In total, 14 cohort studies were included. The results of meta-analysis showed that subclinical hyperthyroidism was associated with the incidence of coronary heart disease (RR=1.19, 95%CI 1.01 to 1.40, P=0.04) and all-cause mortality (RR=1.36, 95%CI 1.11 to 1.67, P=0.003). Conclusions Subclinical hyperthyroidism is associated with an increased risk of CHD and all-cause mortality. Due to the limitation of quality and quantity of the studies, the above conclusions are required to be verified by large-scale and high quality research.

    • Association of cognitive frailty with mortality and hospitalization in older adults: a meta-analysis

      ObjectiveTo systematically review the associations of cognitive frailty with mortality and hospitalization in the elderly. MethodsThe VIP, PubMed, CNKI, WanFang Data, CBM, Embase, Cochrane Library and Web of Science databases were electronically searched to collect cohort studies on the association of cognitive frailty with mortality or hospitalization in the elderly from inception to May, 2023. Two reviewers independently screened the literature, extracted data and assessed risk of bias of the included studies. Meta-analysis was performed by R 4.2.2 software. ResultsA total of 19 cohort studies involving 63 624 elderly were included. The results of meta-analysis showed that compared with healthy elder, the elder with cognitive frailty had a higher mortality (OR=2.75, 95%CI 2.10 to 3.59, P<0.01) and hospitalization (OR=1.67, 95%CI 1.40 to 2.00, P<0.01). Subgroup analysis showed that cognitive frailty was related to the risk of death in different status of frailty and cognitive function, different assessment tools, different countries of development, different follow-up time and research sites. At the same time, different status of frailty and cognitive function and different levels of development of countries were related to the risk of hospitalization. ConclusionCurrent evidence shows that cognitive frailty can increase the risk of hospitalization and mortality in the elderly. It is suggested that early screening and intervention of cognitive frailty should be carried out to effectively reduce the risk of adverse consequences, so as to achieve healthy aging.

    • Analysis on the Causes of Death of Patients with Asthma-Chronic Obstructive Pulmonary Disease Overlap Syndrome

      ObjectiveTo analyze the causes of death of patients with asthma-chronic obstructive pulmonary disease overlap syndrome (ACOS). MethodsA total of 493 patients admitted between January 2006 and Octomber 2015 were respectively analyzed, including 348 asthma patients and 145 ACOS patients. The patients was divided into a survival group and a death group based on the outcome. The ACOS patients were divided into three subgroups based on FEV1% pred level (≥80%, 50%-80%, and < 50%, respectively). The basic characteristics and causes of death were analyzed using χ2-test, t-test and Fish-test based on data type. ResultsThe age (t=3.457, P < 0.001), male proportion (χ2=15.394, P < 0.001) and smoking history (χ2=12.418, P=0.002) had significant differences between the survival group and the death group. The proportion of ACOS patients was higher in the death group (42% vs. 27%, χ2=7.033, P=0.008), and the mortality was also higher in the ACOS patients (21% vs. 12%). The proportion of male patients was higher in the ACOS patients than that in the asthma patients (86% vs. 38%, P < 0.001). The leading three causes of death in the ACOS patients were malignant diseases (45%), pneumonia (26%), and cardiovascular diseases (16%). Malignant diseases were the main cause of death in the ACOS patients with FEV1% pred≥50%, while pneumonia was the main cause of death in those with FEV1% pred≥50%. There was no significant difference in cause of death distribution between three subgroups with different FEV1% pred (P=0.318). ConclusionThe main cause of death of ACOS patients is malignant diseases, the followed are pneumonia and cardiovascular diseases.

    • Validation of European System for Cardiac Operative Risk Evaluation in Heart Valve Surgery of Uyghur Patients and Han Nationality Patients

      ObjectiveTo assess the accuracy of European System for Cardiac Operative Risk Evaluation (EuroSCORE) model in predicting the in-hospital mortality of Uyghur patients and Han nationality patients undergoing heart valve surgery. MethodsClinical data of 361 consecutive patients who underwent heart valve surgery at our center from September 2012 to December 2013 were collected, including 209 Uyghur patients and 152 Han nationality patients. According to the score for additive and logistic EuroSCORE models, the patients were divided into 3 subgroups including a low risk subgroup, a moderate risk subgroup, and a high risk subgroup. The actual and predicted mortality of each risk subgroup were studied and compared. Calibration of the EuroSCORE model was assessed by the test of goodness of fit, discrimination was tested by calculating the area under the receiver operating characteristic (ROC) curve. ResultsThe actual mortality was 8.03% for overall patients, 6.70% for Uyghur patients,and 9.87% for Han nationality patients. The predicted mortality by additive EuroSCORE and logistic EuroSCORE for Uyghur patients were 4.03% and 3.37%,for Han nationality patients were 4.43% and 3.77%, significantly lower than actual mortality (P<0.01). The area under the ROC curve of additive EuroSCORE and logistic EuroSCORE for overall patients were 0.606 and 0.598, for Han nationality patients were 0.574 and 0.553,and for Uyghur patients were 0.609 and 0.610. ConclusionThe additive and logistic EuroSCORE are unable to predict the in-hospital mortality accurately for Uyghur and Han nationality patients undergoing heart valve surgery. Clinical use of these model should be considered cautiously.

    • The incidence and mortality of global bladder cancer from 1990 to 2017

      ObjectivesTo analyze the trend of incidence and mortality of bladder cancer from 1990 to 2017 and the effects of age, time period and birth cohort on bladder cancer incidence and mortality.MethodsData on age-standardized incidence rate (ASIR) and age-standardized death rate (ASDR) of bladder cancer from 1990 to 2017 were extracted from the Global Burden of Disease 2017 (GBD 2017) database. Joinpoint regression model was used to analyze the average annual percentage change of ASIR and ASDR of bladder cancer. The age-period-cohort model was established to analyze the age, period and birth cohort effects on ASIR and ASDR of bladder cancer.ResultsFrom 1990 to 2017, both ASIR and ASDR of bladder cancer decreased slightly. ASIR decreased from 6.42 per 100 000 in 1990 to 6.04 per 100 000 in 2017, with an average annual percentage change of ?0.9% (?1.0% to ?0.8%), and ASDR decreased from 3.15 per 100 000 in 1990 to 2017 2.57/100 000, with an average annual percentage change of ?0.4% (?0.4% to ?0.3%). The age-period-cohort model results showed that as age increased, the risk of bladder cancer incidence and mortality increased; as the birth cohort progressed, the risk of bladder cancer morbidity and mortality decreased. The time period had little effect on the incidence and mortality of bladder cancer.ConclusionsThe incidence and mortality of bladder cancer are declining globally. On the other hand, the increase of the aging global population could reverse the incidence and mortality trend, active measures should be taken to address the adverse effects of aging.

    • Analysis and projection of chronic obstructive pulmonary disease (COPD) burden attributable to air pollution in China, 1990–2021

      ObjectiveTo analyze the disease burden and temporal trends of chronic obstructive pulmonary disease (COPD) attributable to air pollution in China from 1990 to 2021. MethodsUtilizing data from the Global Burden of Disease Study 2021 (GBD 2021), we assessed the burden of COPD attributable to air pollution in China through metrics including death counts, disability-adjusted life years (DALYs), age-standardized mortality rate (ASMR), age-standardized DALY rate (ASDR), annual percentage change (APC), and average annual percentage change (AAPC). A Bayesian Age-Period-Cohort (BAPC) model was employed to project future trends in COPD burden attributable to air pollution. ResultsIn 2021, China’s ASMR and ASDR for COPD attributable to air pollution were 32.57 and 533.84 per 100,000 population, respectively, exceeding global averages. From 1990 to 2021, both ASMR and ASDR exhibited significant declining trends, with AAPCs of ?5.24% (95% CI ?5.78% to ?4.70%) and ?5.28% (95% CI ?5.75% to ?4.81%), respectively. The burden intensified with advancing age and was disproportionately higher among males compared to females. BAPC projections indicate a continued decline in COPD burden from 2022 to 2035, with ASMR expected to decrease from 56.40 to 23.02 per 100,000 and ASDR from 900.14 to 408.64 per 100,000. Conclusion Despite sustained reductions in the burden of COPD attributable to air pollution in China from 1990 to 2021, with further declines anticipated through 2035, national rates remain elevated relative to global benchmarks. Male and elderly populations bear the highest burden, underscoring the urgency for targeted interventions to mitigate air pollution exposure and address health disparities in vulnerable demographics.

    • Clinical Characteristic Analysis of Elderly Patients Undergoing Hemodialysis

      ObjectiveTo study the clinical characteristics of elderly hemodialysis (HD) patients and discuss how to control their complications, in order to improve their quality of life and lower their mortality rate. MethodContrastive study and analysis were performed on the clinical data of 98 maintenance HD patients (between elderly and young HD patients) between January 2013 and January 2014. Complications, rate of hospitalization and mortality were analyzed during the follow-up of one year. ResultsThe ratio of hypertensive kidney disease and diabetic nephropathy, as primary disease of the elderly HD patients, gradually increased. More people chose to use semi-permanent jugular vein catheter for elderly HD patients. Compared with young HD patients, the levels of hemoglobin, albumin, serum creatinine, KT/v were lower in the elderly patients, and C-reactive protein was much higher (P<0.05). There was no significant difference in cholesterol, triglyceride, calcium, phosphorus, parathormone between the two groups (P>0.05). Dialysis-related hypotension and blocking of vascular access occurred more frequently in elderly HD patients. Hospitalization rate and mortality rate were higher in elderly HD patients (P<0.05). ConclusionsImproving nutritional status, keeping vascular access unobstructed for a long time and decreasing complications related to hemodialysis are helpful for elderly HD patients to enhance their quality of life and reduce the mortality rate.

    • Clinical Effect of Noninvasive Positive Pressure Ventilation on Severe Acute Pancreatitis Combined with Acute Lung Injury in Emergency

      ObjectiveTo analyze the effect of noninvasive positive pressure ventilation (NPPV) on the treatment of severe acute pancreatitis (SAP) combined with lung injury [acute lung injury (ALI)/acute respiratory distress syndrome (ARDS)] in emergency treatment. MethodsFifty-six patients with SAP combined with ALI/ARDS treated between January 2013 and March 2015 were included in our study. Twenty-eight patients who underwent NPPV were designated as the treatment group, while the other 28 patients who did not undergo NPPV were regarded as the control group. Then, we observed patients' blood gas indexes before and three days after treatment. The hospital stay and mortality rate of the two groups were also compared. ResultsBefore treatment, there were no significant differences between the two groups in terms of pH value and arterial partial pressure of oxygen (PaO2) (P>0.05). Three days after treatment, blood pH value of the treatment group and the control group was 7.41±0.07 and 7.34±0.04, respectively, with a significant difference (P<0.05); the PaO2 value was respectively (60.60±5.11) and (48.40±3.57) mm Hg (1 mm Hg=0.133 kPa), also with a significant difference (P<0.05). The hospital stay of the treatment group and the control group was (18.22±3.07) and (23.47±3.55) days with a significant difference (P<0.05); and the six-month mortality was 17% and 32% in the two groups without any significant difference (P>0.05). ConclusionIt is effective to treat patients with severe acute pancreatitis combined with acute lung injury in emergency by noninvasive positive pressure ventilation.

    • Analysis on the status and temporal trend of dementia burden in Guangzhou from 2008 to 2019 and burden attributable to smoking

      Objective To analyze the characteristic and temporal trend in mortality and disease burden of Alzheimer’s disease (AD) and other forms of dementia in Guangzhou from 2008 to 2019, and estimate the disease burden attributable to smoking to provide evidence for promoting local health policy of prevention and intervention of dementia. Methods Based on the data of Guangzhou surveillance point of the National Mortality Surveillance System (NMSS), the crude mortality, standardized mortality, years of life lost (YLL) of AD and other dementia were calculated. The indirect method was used to estimate years lived with disability (YLD) and disability-adjusted life years (DALY).The distribution and changing trends of the index rates were compared from 2008 to 2019 using Joinpoint Regression Program. Based on the data of Guangzhou Chronic Disease and Risk Factors Monitoring System in 2013, the indexes of disease burden of AD and other forms of dementia attributable to smoking in 2018 was calculated. Results The standardized mortality rate, YLL rate, YLD rate and DALY rate of AD and other forms of dementia in Guangzhou increased from 0.45/100 000, 0.05‰, 0.02‰ and 0.07 ‰ in 2008 to 1.28/100 000, 0.15‰, 0.07‰ and 0.22‰ in 2019, respectively. The average annual changing trend was statistically significant (AAPC=11.30%, 13.09%, 13.09%, 13.09%, P<0.001). In most years, the mortality and disease burden of women were higher than those of men, but men had higher growing trend than women in standardized mortality rate, YLL rate, YLD rate and DALY rate from 2008 to 2019, with a slower growing speed after the year 2012.The disease burden of dementia attributable to smoking in men was significantly higher than that in women. Conclusion The mortality and disease burden of AD and other forms of dementia in Guangzhou have dramatically increased over the past twelve years. Intervention against modifiable factors such as smoking, and prevention and screening for dementia in key populations should be strengthened. Support policies for dementia care management should be adopted to reduce the disease burden caused by premature death and disability.

    • Effect of Alanyl-glutamine Dipeptide on Insulin Resistance and Outcomes in Critically Ill Patients With Chronic Obstructive Pulmonary Disease and Respiratory Failure

      Objective We investigated the effect of supplementation with alanyl-glutamine dipeptide on insulin resistance and outcome in patients with chronic obstructive pulmonary disease (COPD) and respiratory failure. Methods A prospective, randomized, open and controlled trial was conducted. Patients with COPD and respiratory failure were recruited between Jan 2005 to Feb 2006 and randomly assigned to a trial group (n=14) with glutamine dipeptide supplmented parenteral nutrition and a control group (n=16) with isocaloric, isonitrogenic parenteral nutrition. On the third day and fifth day of nutrition treatment, blood glucose was clamped at level of 4.4 to 6.1 mmol/L by intravenously bumped insulin. Blood gas, blood glucose level, insulin dosage were recorded everyday. The outcomes were mortality, length of stay (LOS) in hospital and in ICU, mechanical ventilation times and the costs of ICU and hospital.Results Thirty patients successfully completed the trial. There was no difference in blood gas between two groups, but PaO2 increased gradually. Compared with control group, blood glucose level had trend to decrease in trial group. The average insul in consumption decreased significantly in trial group on the fifth day. There was no statistical difference between two groups in mortality, length of stay in hospital and the costs of hospital. But compared with control group, length of stay in ICU and mechanical ventilation days had trend to decrease in trial group. Conclusion Alanyl-glutamine dipeptide do not improve pulmonary function of patients with COPD and respiratory failure. However, alanyl-glutamine dipeptide attenuated insul in resistance and stabilized blood glucose. This trial does not confirm alanyl-glutamine di peptide can improve outcome in critically ill patients with COPD and respiratory failure between two groups in mortality at the end of 30 days, length of stay in hospital and the costs of hospital. But the length of stay in ICU and the duration of mechanical ventilation does decrease, but not significantly, in the trial group.
