RESUMEN
ObjectiveTo study the epidemiological characteristics of deaths due to pneumoconiosis and its complications in order to improve the prevention and management of pneumoconiosis. MethodsThe pneumoconiosis deaths who died during 1959‒2019 in Chongming District of Shanghai were investigated and analyzed retrospectively by the descriptive epidemiological methods. The correlation of the age of onset and the course of disease was analyzed by Spearman rank correlation,as well as the duration of dust exposure and the course of disease in pneumoconiosis patients. ResultsFrom 1959 to 2019, there were 226 pneumoconiosis deaths, 223 males (98.67%). The mortality of silicosis was the highest (82.07%). The age of onset of pneumoconiosis was negatively correlated with the course of disease (rs=-0.596,P<0.001).There was no correlation between the duration of dust exposure and the course of disease in pneumoconiosis patients (rs=-0.107,P=0.109).There were statistically significant differences in mortality among groups in different types and stages of pneumoconiosis(χ2=59.250,27.666,both P<0.05). The mortality increased with the increase of stage of pneumoconiosis. The mortality of pneumoconiosis was significantly different in 1959‒1979, 1980‒1989, 1990‒1999, 2000‒2009 and 2010‒2019 (χ2=29.750, P<0.05). The top three causes of death in pneumoconiosis cases were respiratory diseases, malignant tumor and cardiovascular and cerebrovascular diseases.ConclusionIt is suggested to further strengthen the health monitoring and management of pneumoconiosis patients,control lung and chronic respiratory diseases to delay the life expectancy and improve quality of life of pneumoconiosis patients.
RESUMEN
Long QT syndrome is one of the most common hereditary channelopathies inducing fatal arrhythmias and sudden cardiac death. We identified in a sudden arrhythmic death syndrome case a C-term KCNH2 mutation (c.3457C > T; p.His1153Tyr) classified as variant of unknown significance and functional impact. Heterologous expression in HEK293 cells combined with western-blot, flow-cytometry, immunocytochemical and microscope analyses shows no modification of channel trafficking to the cell membrane. Electrophysiological studies reveal that the mutation causes a loss of HERG channel function through an alteration of channel biophysical properties that reduces the current density leading to LQT2. These results provide the first functional evidence for H1153Y-KCNH2 mutation-induced abnormal channel properties. They concur with previous biophysical and clinical presentations of a survived patient with another variant that is G1036D. Therefore, the present report importantly highlights the potential severity of variants that may have useful implications for treatment, surveillance, and follow-up of LQT2 patients.

AIM: In Japan, the frequency of maternal deaths due to obstetric hemorrhage has been decreasing in the last decade, while that resulting from other causes such as pulmonary thromboembolism (PTE) was consistent. To help reduce maternal deaths due to PTE, we investigated PTE during pregnancy and puerperium and compared the survival and death cases, and aimed to find out life and death factors. METHODS: This study was a retrospective analysis based on a clinical chart review in 407 maternal and perinatal centers. We compared the survival and death cases of PTE during pregnancy and puerperium from 2013 to 2017. RESULTS: In PTE during pregnancy, the survival cases underwent significantly earlier diagnoses than the death cases, and thromboprophylaxis was performed in most of both the survival and death cases of PTE during puerperium according to the existing Japanese guidelines; however, only one fourth of the total cases underwent anticoagulation to prevent venous thromboembolism (VTE). CONCLUSIONS: Early diagnosis of PTE in suspected cases was associated with better survival during pregnancy.

Objective:To understand the influencing factors of death of epidemic Japanese encephalitis (EJE) cases in Longnan City of Gansu Province.Methods:In the EJE Monitoring Information Report Management System of the Chinese Disease Prevention and Control Information System, data on EJE cases with onset from 2014 to 2018 and current address in Longnan City were derived. An "Individual Questionnaire of Epidemic Japanese Encephalitis in Longnan City" was designed, retrospective study was conducted on enrolled cases, their information on demographic data, consultation, onset, clinical classification, and chronic underlying diseases were collected, characteristics of EJE cases and death-related factors were analyzed.Results:From 2014 to 2018, a total of 260 EJE cases were reported in Longnan City, and 259 cases completed the questionnaire. Among them, 70 cases (27.0%) were aged ≥60 years old, 67 cases (25.9%) were severe and extremely severe, and 55 cases (21.2%) had chronic underlying diseases. Among 259 EJE cases, 46 cases died, with a fatality rate of 17.8%. After multivariate unconditional logistic regression analysis, age ≥60 years old [odds ratio ( OR)=2.667, 95% confidence interval ( CI): 1.140-6.237], severe and extremely severe ( OR = 2.762, 61.820, 95% CI: 1.053-7.091, 5.149-742.239), and chronic underlying diseases ( OR = 2.489, 95% CI: 1.038-5.964) were risk factors for death in EJE cases. Conclusions:The influencing factors of death of EJE cases in Longnan City are age, clinical classification and chronic underlying diseases. Therefore, we should focus on patients over 60 years old, clinically classified as severe or extremely severe, and suffering from chronic underlying diseases, and strengthen the immunization of EJE vaccine for key populations.
RESUMEN
【Objective】 To investigate the clinical characteristics of COVID-19 induced deaths and analyze the causes of death. 【Methods】 This was a hospital-based, retrospective, observational cohort study involving hospitalized patients diagnosed with COVID-19 in People’s Hospital of Wuhan University during January 27 and February 25, 2020. The clinical data of identified patients who had died of COVID-19 were retrieved and reviewed. We analyzed the death causes and compared the changes in laboratory findings between patients before death and early onset to summarize the inherent clinical characteristics. 【Results】 We recorded a total of 21 deaths, 61.9% of which had occurred due to simple respiratory failure, followed by respiratory failure with myocardial injury (19%), respiratory failure with renal failure (9.5%), and respiratory failure with shock (9.5%). At the late time, lab test data indicated that white blood cells, D-dimer, amino-terminal brain natriuretic peptide precursors, and hypersensitive C-reactive protein significantly increased while counts of lymphosyte significantly decreased (P<0.05). 【Conclusion】 Continuous monitoring of cardiac function, renal function, and infection severity can assess the disease progression accurately. Moreover, timely intervention has a positive effect in reducing COVID-19 mortality.
RESUMEN
It is an essential task to discuss the death cases for clinicians. During the emergent public events, the report and analysis of death cases is of far-reaching significance. The epidemic of coronavirus disease 2019(COVID-19) has brought huge losses to China, and the medical system has been sustaining tremendous pressure. The best weapon to defeat the epidemic is medical data and related scientific research, of which the systematic analysis and efficient use of death cases is a key step. Based on the incomplete record of death case report, the lack of humanistic perspective and patient report, every department and institution is facing great challenge in terms of data management. Given that the relevant systems need to be improved, and that the integration of standardized reports and clinical research is not mature,as well as other problems, we put forward several methodological suggestions: â Establish national medical and health data center and improve relevant laws and regulations. â¡ Increase investment in medical data management and start data collection and analysis as early as possible during the epidemic. ⢠Refine the content of death case report and promote the standardization of report. ⣠Pay close attention to the report of death cases, review, summary and analysis. More importantly, we should continue to build and improve platforms and programs related to disease control, carry out epidemic-associated scientific research, enhance the managing efficiency of public health data, elevate the anti-risk capability of our medical system, and promote the steady progress of the health China strategy.

OBJECTIVE: To understand the epidemiological characteristics of death cases of echinococcosis in China from 2008 to 2016, so as to provide an important reference for the prevention and control of echinococcosis. METHODS: The death information registration and management system data were selected to analyze the epidemiological characteristics of the death cases of echinococcosis. The data were analyzed by SPSS 21.0 and the map was drawn by ArcGIS 10.1 software. RESULTS: From 2008 to 2016, a total of 367 death cases of echinococcosis were reported in China, and the number of deaths in turn was 33, 30, 21, 32, 35, 54, 55, and 81 in each year, with an annual average crude mortality of 129.29 /105. The average age of death was (56 ± 18) years; the sex ratio of male to female was 100â¶94. There was no statistical difference between the male and female death cases (χ2 = 0.33, P > 0.05).The death cases of echinococcosis were mainly distributed in endemic areas of Qinghai, Sichuan, Ningxia, Xinjiang, Gansu, Inner Mongolia, Yunnan and non-endemic areas of Heilongjiang, Jiangsu, Henan and Shandong. The death cases in the first eleven provinces accounted for 87.5% (321/367) of the total death cases, among which the highest proportions of the nationality, occupation, educational level, highest diagnostic units, and the place of death were Han (52.0%, 191/367), farmer (46.6%, 171/367), junior high school or below (57.2%, 210/367), provincial or three-level hospitals (46.6%, 171/367), and at home (59.9%, 220/367). CONCLUSIONS: Since 2014, the death cases of echinococcosis in China have been increasing year by year, indicating that the prevention and treatment of echinococcosis is still very serious. The causes for the rise of the fatality rate remain to be further studied.

RESUMEN
Objective: To analyze and investigate the survival time of dead HIV/AIDS patients after antiretroviral therapy (ART) and related factors in Henan province. Methods: The database of national integrated management system of HIV/AIDS was used to collect the information of dead patients who received ART between January 2003 and December 2015. Software SPSS 23.0 was used to analyze the survival time of dead patients and related factors. Result: A total of 6 267 AIDS patients died after ART and the average survival time was 23.85 months (Q(R): 6.87-50.46 months). Within 6 months, 7-12 months and 13-24 months after ART, the numbers of dead patients were 1 441 (23.00%), 652 (10.40%) and 1 052 (16.79%), respectively. The number of dead cases decreased after 24 months of ART. The number of AIDS-related deaths was 5 085 (81.1%); and 799 (12.7%) deaths were due to other causes, in which 179 (2.9%) were caused by accidents and 109 (1.7%) were caused by suicides. The differences in annual composition ratio of death causes during 2003-2015 had significance (χ(2)=864.27, P<0.01). Twelve months, 36 months, 60 months and 120 months after ART, the survival ratios were 66.59%, 36.62%, 19.24% and 0.64% respectively. Compared with patients infected through blood donation, the HR of the patients infected through sexual transmission was 1.602 (95%CI: 1.483-1.732). Compared with patients with initial level of CD(4)(+)T lymphocyte ≥350 unit/µl, the HR of patients with initial level of CD(4)(+)T lymphocyte<50 unit/µl was 2.320 (95%CI: 2.119-2.539). Compared with patients receiving second line ART, the HR of patients receiving no second line ART was 3.312 (95%CI: 3.083-3.558). Conclusion: The AIDS related deaths mainly occurred in the first six months after ART. As the increase of duration of ART, the death rate decreased. Sexual transmission, low initial level of CD(4)(+)T lymphocyte and receiving no second line ART were the risk factors for the deaths of HIV/AIDS patients.

Objective:To analyze the cause of patients with hepatic failure induced by viral hepatitis to provide guidance for the clinical treatment. Methods:Retrospective analysis was adopted to study the clinical data of 115 patients died of hepatic failure induced by viral hepatitis enrolled in our department for five years.The data of each case was collected from the check of final diagnosis and the last check before death. Results:Of all 115 patients,103 cases were male,12 cases were female. with an average age of 45.7 years.There were 89 cases with chronic severe hepatitis,20 cases with cirrhosis.114 cases infected hepatitic B virus including 12 cases with superfection of HAV,HDV,HEV.Of 110 cases,24 were HBeAg positive24/ 110,21.8%),61 were HBeAb positive(61/110,55.5%). Of 85 cases,HBV DNA quantity of 68 cases was more than 1?105 copies/m(l68/85,80%),HBV DNA quantity of 17 cases was less than 1?10(517/85,20%).TBil,PTA and ALT at admission were 403.17 ?219.43,38.33 ?19.14 and 496.78 ?801.56 respectives,while those at death were 478.03 ?234.89,32.39 ? 16.54,218.04?426.58 respectively.Severe complications presented. Conclusion:In our country,hepatic failure was mainly induced by chronic severe hepatitis and cirrhosis infected with hepatitis B virus. The active replication of HBV DNA and the viral mutation could be causes of the development of disease. As the incidence rate of complications is high,preventing complication is necessary to reduce fatality rate of the patients with hepatic failure.
