Death Trend of Lung Cancer in China from 2006 to 2020 Based on Age-Period-Cohort Model / 肿瘤防治研究

Objective To analyze the trend of lung cancer death rate in China from 2006 to 2020 to provide reference for the prevention of lung cancer. Methods The data of Chinese lung cancer deaths from 2006 to 2020 were collected from the health statistical yearbook.The age-period-cohort model and intrinsic estimator algorithm were used to evaluate the age, period, and birth cohort effect of lung cancer deaths. Results The overall lung cancer mortality of Chinese residents showed an upward trend from 2006 to 2020.The age effect of lung cancer death risk increased with age, and the period effect continued to increase with age.The cohort effect showed that the lung cancer death risk of residents born after 1924 showed a downward trend. Conclusion The prevention and treatment of lung cancer in urban and rural residents aged 50 and above and the treatment of high-risk factors of lung cancer must be continuously strengthened.The period effect on lung cancer should be further explored, and the early intervention of young cohort should be given attention.

Perinatal Mortality among All Deliveries in a Tertiary Care Center: A Descriptive Cross-sectional Study.

INTRODUCTION: Perinatal mortality comprises the number of stillbirths and death of newborns within seven days of life which is the main contributor to infant and maternal mortality. The aim of this study was to find out the prevalence of perinatal mortality among all the deliveries in a tertiary care center of a remote part of Nepal. METHODS: This was a descriptive cross-sectional study conducted in a tertiary care center located in Jumla among 3798 deliveries (childbirth) from August 2014 to April 2020. Ethical approval was taken from the institutional review committee (2076/2077/05) of the same institution. A convenience sampling technique was used and the data were collected from the medical record section and then entered and analyzed in Statistical Package for Social Sciences version 16. Point estimate at 95% Confidence Interval was calculated along with frequencies and percentages for binary data. RESULTS: The prevalence of perinatal mortality was 187 (4.92%) (4.23-4.60% at 95% Confidence Interval) among 3798 deliveries. Regarding the primary causes; the highest proportion was intrapartum hypoxia 62 (33.3%), spontaneous preterm labor 40 (21.5%), and congenital anomalies 38 (20.4%). Similarly, about the final cause; the highest proportion was birth asphyxia 64 (34.2%), intrauterine fetal death 51 (27.3%), congenital anomalies 35 (18.7%), and complication of prematurity 32 (17.1%). CONCLUSIONS: The perinatal mortality was quite high in this study with respect to similar studies done in other countries. The finding of this study showed that quality antenatal care with rural ultrasound service is essential to reduce the causes of perinatal mortality.

Analysis on the characteristics and trend of injury death among the elderly aged 65 and above in Chongqing / 公共卫生与预防医学

Objective To analyze the characteristics and changing trend of injury death among elderly residents aged 65 and above in Chongqing from 2013 to 2017, and to provide a basis for formulating intervention strategies for elderly injuries. Methods Based on monitoring data of death causes of permanent residents in Chongqing from 2013 to 2017, the injury death cases of elderly residents aged 65 and above were extracted, and the mortality rate and sequence were calculated. The standard mortality rate was calculated based on the standard population composition of the sixth national population census in 2010. The Joinpoint Regression Program 4.2 software was used to analyze the death trend. Results From 2013 to 2017, the average annual crude injury mortality rate of Chongqing residents aged 65 and above was 140.89/100 000, and the standardized mortality rate was 12.57/100 000. The crude death rate of male elderly residents was higher than that of female residents in the same year (P <0.001), and the injury mortality rate increased with the age of the elderly (P <0.001). The injury mortality rate of female and all elderly residents, and elderly residents in the 75- and 85-year-old groups showed an upward trend (P<0.05). Falls, road traffic injuries, suicide, other accidental injuries and drowning were the top five causes of injury death in Chongqing, accounting for 93.16% of the total injury deaths. In the past five years, the fall mortality of elderly residents in Chongqing showed an upward trend (P < 0.05). Falling was the first cause of injury death for elderly aged 70 and above in Chongqing. The crude rate of death of elderly residents aged 85 and over was 313.52 /100 000. Conclusion The injury mortality and fall mortality of elderly residents aged 65 and above in Chongqing showed a rising trend in the past five years. It is urgent to take measures to prevent injury and falls for seniors in Chongqing.

Road death trend in the United States: implied effects of prevention.

This study estimates road deaths prevented by U.S. vehicle safety regulations, state laws, and other efforts based on comparison of actual deaths to those predicted from temperature and precipitation effects on exposure, migration to warmer areas, population growth, median age of the population, and vehicle mix. Logistic regression of risk factors predictive of road deaths in 1961, prior to the adoption of federal vehicle safety regulations, state behavioral change laws, and other preventive efforts were used to predict deaths in subsequent years given the changing prevalence of the risk factors from 1962 to 2015. The included risk factors are strong predictors of road death risk. Without the preventive efforts, an additional 5.8 million road deaths would likely have occurred in the U.S. from the initiation of federal safety standards for new vehicles in 1968 through 2015.
