ABSTRACT
ABSTRACT Objetive: To provide a comprehensive analysis of mortality trends from acute pesticide poisoning in Mexico from 2000 through 2021. Methods: The governmental records of deaths from acute pesticide poisoning were used. The age-standardized years of life lost and aged-standardized mortality rates were estimated. Significant changes in trends of annual percentage change were identified using Joinpoint regression. Results: Between 2000 and 2021, mortality was primarily observed in individuals aged 15 to 19 years. Males were the most affected. Self-inflicted pesticide poisoning was the primary registered reason for death. The age-standardized mortality rate from acute pesticide poisoning was reduced from 2012 to 2021 (APC: -4.4; p=0.003). Conclusion: This report is the first study about the mortality rate from acute pesticide poisoning in Mexico. The results provided evidence to consider in developing laws to prevent acute pesticide poisoning.
RESUMO Objetivo: Fornecer uma análise abrangente das tendências de mortalidade por envenenamento agudo por pesticidas no México de 2000 a 2021. Métodos: Foram usados os registros governamentais de mortes por envenenamento agudo por pesticidas. Foram estimados os anos de vida perdidos estandardizados por idade e as taxas de mortalidade estandardizados por idade. Modificações significativas nas tendências de variação percentual anual foram identificadas usando a regressão Joinpoint. Resultados: Entre 2000 e 2021, a mortalidade foi observada principalmente em indivíduos na faixa etária de 15 a 19 anos. Os homens foram os mais afetados. O envenenamento por pesticida autoinfligido foi o principal motivo de morte registrado. A taxa de mortalidade estandardizada por idade por intoxicação aguda por pesticidas foi reduzida de 2012 a 2021 (Annual Percent Change — APC: -4,4; p=0,003). Conclusão: Este relatório é o primeiro estudo sobre a taxa de mortalidade por intoxicação aguda por pesticidas no México.

ABSTRACT
@#Objective To analyze the trend of the hemagglutinin(HA) and ovalbumin contents in the lot release of influenza virus split vaccines in 2021,and evaluate the quality and quality control level of the vaccines.Methods The HA and ovalbumin content data of influenza virus split vaccines from two domestic enterprises in 2021 were collected and collated. The mean value and standard deviation were calculated according to the first 40 batches of data of the enterprise in the year,and the warning limit and action limit were established. The trend analysis of the above indexes was carried out to evaluate the stability and consistency of the product quality of the enterprise. Statistical data comparison and consistency analysis were made between the test results of the batch inspected by the lot release institution and the results of the enterprise.Results Through the retrospective data analysis of quadrivalent influenza virus split vaccines from two vaccine enterprises A and B,it was found that the content of H1N1 subtype HA and ovalbumin in the two enterprises and the content of Bv HA in the B enterprise had out of trend(OOT)situations,while the trend of other items was stable. The results of paired student's t test or Wilcoxon signed-rank test of the samples inspected by the lot release institution showed that except Bv subtype HA(t = 1. 094 and 0. 742 respectively)and ovalbumin(w =-64 and 36 respectively)contents showed no statistically significant difference(P > 0. 05),the HA contents of H1N1(t = 3. 862,w = 232),H3N2(t = 8. 225 and3. 473 respectively)and By(t = 5. 616 and 4. 934 respectively)of the two enterprises had significant differences(P <0. 05). The results of enterprises were generally higher than the lot release institution. Bland-Altman test analysis found that the consistency between the test data of enterprise A's HA content and the data of the lot release institution was better than that of enterprise B.Conclusion The stability and consistency of data trends of active ingredients and main impurity ingredients of quadrivalent influenza virus split vaccine batches in 2021 were generally good. The trend analysis can identify potential problems in vaccine production,and enterprises should carefully implement trend analysis and effectively monitor the product quality of vaccines.
ABSTRACT

The DALY rate, YLL rate and YLD rate caused by lower gastrointestinal bleeding in the past 10 years showed an upward trend (P<0.05). Conclusion The microscopic examination rate of lower gastrointestinal bleeding in children was graduallyincreasing,and the prevalence rate of basic diseases such as boys,hypertension and gastroenteritis was increasing;in addition,the disease burden caused by children's lower gastrointestinal bleeding was also increasing year by year and should be protected.
ABSTRACT
El presente estudio de carácter descriptivo y analítico tiene como objetivo principal presentar el comportamiento criminal en Colombia para el 2022, desde un enfoque cuantitativo empleado para la extracción, análisis e interpretación de los registros administrativos del Sistema de Información Estadístico, Delincuencial, Contravencional y Operativo (SIEDCO), constituyéndose como un insumo para aquellos interesados en el estudio de la dinámica criminal, así como para quienes se encargan de diseñar estrategias para la contención del delito y la generación de política pública en materia de seguridad. En este sentido y en el marco de las dinámicas sociodemográficas, en una primera parte se aborda de manera general el proceso de homogenización de los registros administrativos llevado a cabo por la Policía Nacional y la Fiscalía General de la Nación. Y en una segunda parte, con especial énfasis en el homicidio intencional, se presenta el análisis de la información que permitió identificar las principales variables que influyen en la comisión del delito, de acuerdo con las cifras contenidas en el SIEDCO, en el periodo comprendido entre el 1 de enero y el 31 de diciembre de 2022, comparado con la misma temporalidad del 2021, en el que se detallan los delitos que afectan la integridad personal y el patrimonio económico de quienes habitan el territorio colombiano; se hallaron incrementos considerables en estos y se resaltan los factores de oportunidad para su comisión, situación contraria a la que se evidenció sobre las afectaciones a la vida y la integridad, conjunto de conductas que, según lo registrado, decrecieron en el periodo analizado. Finalmente, se ofrece un aporte a la contención desde la actividad de policía y una serie de conclusiones que permitan ampliar la visión sobre los diversos fenómenos y enriquecer la generación de conocimiento en el campo de la criminología.
The main objective of this descriptive and analytical study is to present criminal behaviour in Colombia for 2022, from a quantitative approach used for the extraction, analysis and interpretation of the administrative records of the Statistical, Criminal, Contraventional and Operational Information System (SIEDCO), constituting an input for those interested in the study of criminal dynamics, as well as for those responsible for designing strategies for the containment of crime and the generation of public policy on security. In this sense, and within the framework of socio-demographic dynamics, the first part of the paper deals in a general way with the process of homogenisation of administrative records carried out by the National Police and the Attorney General's Office. The second part, with special emphasis on intentional homicide, presents the analysis of the information that made it possible to identify the main variables that influence the commission of the crime, according to the figures contained in SIEDCO, in the period between 1 January and 31 December 2022, compared with the same period in 2021, in which the crimes that affect the personal integrity and economic patrimony of those who live in Colombian territory are detailed; considerable increases were found in these and the factors of opportunity for their commission are highlighted, contrary to the situation that was evidenced in the affectations to life and integrity, a group of conducts that, according to what was recorded, decreased in the period analysed. Finally, we offer a contribution to containment from the police activity and a series of conclusions that allow us to broaden the vision of the diverse phenomena and enrich the generation of knowledge in the field of criminology.

Introducción. El feto que no alcanza el potencial de crecimiento esperado en el útero se considera pequeño para la edad gestacional (PEG). Esta restricción depende de factores genéticos y/o ambientales; la altura geográfica es uno muy relevante. Este trabajo analiza la distribución espacial de las prevalencias de PEG y su tendencia secular en Jujuy (1991-2014). Materiales y métodos. Se analizaron los registros de 308 469 nacidos vivos de Jujuy (Dirección de Estadísticas e Información de Salud). Se estimaron prevalencias de PEG (peso/edad gestacional
Introduction. A fetus that does not reach the expected growth potential in utero is considered small for gestational age (SGA). Such restriction depends on genetic and/or environmental factors, being altitude a very relevant factor. This study analyzes the spatial distribution of the prevalence of SGA and its secular trend in Jujuy (19912014). Materials and methods. The records of 308 469 live births in Jujuy (Health Statistics and Information Department) were analyzed. The prevalence of SGA (weight/gestational age < P10 and < P3) was estimated for sex according to the INTERGROWTH-21 st standard in the ecoregions of Jujuy (Valle and Ramal less than 2000 MASL, Puna, and Quebrada) across 3 periods (19912000, 20012009, 20102014) and proportions were compared. The secular trend was assessed using the Joinpoint regression analysis. Results. The overall prevalence of SGA was 2.3% (< P3) and 7% (< P10). Significantly higher values were observed in Puna and Quebrada in both SGA categories and across all periods. Only in Valle, significant differences were observed between sexes across all periods. The prevalence of SGA showed a significant downward secular trend at a provincial and regional level, and this was greater in Quebrada (5.2% < P3 and 3.5% < P10). Conclusions. A consistent and significant decrease in the prevalence of SGA has been observed since the 1990s in Jujuy, where altitude is itself a determining factor of size at birth, since the Puna and Quebrada regions showed the highest prevalence of SGA during the entire period.

Objective:To investigate the change trend of etiological burden of disease of liver cancer in the Chinese population from 1990 to 2019.Methods:The descriptive epidemiologic method was conducted. Based on the Global Burden of Disease data from the Institute for Health Metrics and Evaluation at the University of Washington, the data related to liver cancer burden caused by hepatitis B virus (HBV) infection, hepatitis C virus (HCV) infection, alcohol, nonalcoholic steatohepatitis (NASH) and other factors, including number of new cases, the crude incidence rate, age-specific incidence rate, number of deaths, crude mortality rate and age-specific mortality rate, in the Chinese population from 1990 to 2019 were collected. The age-standardized rate was calculated based on the world standardized population structure in 2019 from the Global Burden of Disease data. Observation indicators: (1) the incidence of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019; (2) the mortality of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019; (3) the change trend of age-specific incidence rate of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019; (4) the age-specific mortality rate of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. Count data were expressed as absolute numbers, percentages and ratio. Based on the junction point regression model, the Joinpoint software (V.4.9.1.0) was used to calculate the annual percentage change, average annual percentage change (AAPC) and 95% confidence intervals ( CI) of age-specific incidence rate and age-specific mortality rate of liver cancer caused by different etiologies. Results:(1) The incidence of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. From 1990 to 2019, the number of new cases of liver cancer in Chinese population decreased from 236 825 to 210 462, and the crude incidence rate decreased from 20.01/100,000 to 14.80/100,000. The new cases of liver cancer caused by HBV infection, HCV infection and other factors showed a downward trend, and the absolute change rates were ?14.76%, ?3.98% and ?26.67%, respectively. The new cases of liver cancer caused by alcohol and NASH showed a increase trend, and the absolute change rates were 9.31% and 13.91%, respectively. (2) The mortality of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. From 1990 to 2019, the number of deaths of liver cancer in Chinese population decreased from 232 449 to 187 700, and the crude mortality rate decreased from 19.64/100,000 to 13.20/100,000. The number of deaths of liver cancer caused by HBV infection, HCV infection and other factors showed a down-ward trend, and the absolute change rates were ?23.34%, ?10.99% and ?33.75%, respectively. The number of deaths of liver cancer caused by alcohol showed a slow downward trend, and the absolute change rate was ?0.51%. The number of deaths of liver cancer caused by NASH showed a increase trend, and the absolute change rate was 6.03%. (3) The change trend of age-specific incidence rate of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. From 1990 to 2019, the AAPC of age-specific incidence rate of liver cancer caused by HBV infection, HCV infection, alcohol, NASH and other factors was ?3.61%(95% CI as ?4.10% to ?3.11%), ?3.57%(95% CI as ?3.99% to ?3.14%), ?2.79%(95% CI as ?3.24% to ?2.33%), ?2.65%(95% CI as ?3.09% to ?2.21%) and ?3.62%(95% CI as ?4.05% to ?3.19%), respectively. (4) The age-specific mortality rate of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. From 1990 to 2019, the AAPC of age-specific mortality rate of liver cancer caused by HBV infection, HCV infection, alcohol, NASH and other factors was ?3.92%(95% CI as ?4.42% to ?3.41%), ?3.90%(95% CI as ?4.45% to ?3.35%), ?3.15%(95% CI as ?3.71% to ?2.58%), ?2.86%(95% CI as ?3.34% to ?2.38%) and ?4.09%(95% CI as ?4.64% to ?3.55%), respectively. Conclusions:From 1990 to 2019, the liver cancer burden of the Chinese population shows an overall downward trend, in which the liver cancer burden caused by HBV and HCV infection decreases the most, but HBV and HCV infection is still the main reason for the heavy burden of liver cancer. The age-specific incidence rate and age-specific mortality rate of liver cancer caused by alcohol and NASH show a downward trend, but the number of new cases of liver cancer caused by alcohol and NASH shows significant growth. The liver cancer burden caused by other factors shows a downward trend.

ABSTRACT
ObjectiveTo determine the death level， change trend and life loss of pancreatic cancer among residents in Yuyao， and to provide scientific reference for the prevention and control of pancreatic cancer. MethodsThe death monitoring data of registered residents in Yuyao from 2014 to 2021 were collected to calculate crude mortality rate（CMR）， standardized mortality rate （SMR）， potential years of life lost （PYLL）， average years of life lost （AYLL）， PYLL rate （PYLLR）， average annual percent change （AAPC） and other indicators. ResultsFrom 2014 to 2021， 860 cases of pancreatic cancer died in Yuyao， accounting for 6.25% of all malignant tumor deaths in the same period. The average annual mortality rate was 12.86/100 000， the age-standardized rate by Chinese standard population （ASRC） was 7.08/100 000， and the age-standardized rate by world Segi’s population （ASRW） was 5.17/100 1000. The CMR showed an upward trend in eight years （t=-5.076， P=0.002）. 493 men died of pancreatic cancer with an average annual mortality of 14.95/100 000， ASRC of 8.13/100 000， and ASRW was of 6.24/100 000. 367 women died of pancreatic cancer with an average annual mortality rate of 10.82/100 000， ASRC of 6.02/100 000， and ASRW of 4.14/100 000. The mortality rate of men was higher than that of women （χ2=22.191， P<0.001）. The minimum death age of pancreatic cancer is 27.52 years old， the maximum death age is 94.52 years old， and median age （Q1， Q2） of death was ［71.13（63.21， 78.87）］ years old. The death age of men ［69.61（62.30， 77.06）］ was less than that of women ［72.48（64.63， 81.09）］ （t=-3.820， P<0.001）. The mortality rate of pancreatic cancer showed an upward trend with age （χ2trend=1 110.844， P<0.001）， and the 75 year old mortality rate （75.58/100 000） fell after reaching the peak. PYLL caused by death of pancreatic cancer in 8 years was 9 775.00 person years， AYLL was 14.33 person years， and PYLLR was1.53‰. ConclusionPancreatic cancer is an important cause of death for residents in Yuyao， which has a huge loss of life. It is necessary to formulate targeted prevention and control strategies， with the middle-aged and elderly as the key population， to reduce the incidence and death of pancreatic cancer.
ABSTRACT
ObjectiveTo analyze the epidemic trends and current status in the prevalence of schistosomiasis in Jiangxi Province from 2002 to 2021， and to provide evidence for formulating and optimizing schistosomiasis control strategies in the province. MethodsEpidemiological data of schistosomiasis in Jiangxi Province from 2002 to 2021 were collected. The Joinpoint regression model was used to investigate the epidemic trends of schistosomiasis， and the annual average percent change （AAPC） was used to assess the changing trend of schistosomiasis infection in humans and bovines. SPSS 25.0 software was used to analyze the target achievement status， infection rate of schistosomiasis in humans and the areas with snails in 2021 to evaluate the differences among various districts and epidemic regions. ResultsBy 2021， 24 counties （61.50%） in the province had achieved the elimination goal， with hilly and marsh counties reaching 82.60% and 31.30%， respectively. The seropositive rate of schistosomiasis in human was 3.51% across the province. However， the seropositive rate in marshland areas （4.77%） was significantly higher than that in hilly areas （1.23 %） （χ2=3 827.51， P<0.001）. The total area with snails in the province was 84 938.32 hm2， including 82 196.86 hm2 in marshland areas and 2 741.46 hm2 in hilly areas. From 2002 to 2021， the infection rate of schistosomiasis in the humans and bovines exhibited a declining trend， with AAPC values of -48.70 and -39.70， respectively. The decline rate in the hilly areas was higher than that in marshland areas. However， the area with snail showed an upward trend （AAPC=0.50）， with a growth rate of 5.80% in hilly areas， which was greater than that in marshland areas （0.40%）. ConclusionFrom 2002 to 2021， the infection rate of schistosomiasis in humans and bovines in Jiangxi Province continued to decline， while the areas with snails increased. The prevention focus should still be on the marshland endemic areas， and attention should also be given to the risk of schistosomiasis in hilly endemic areas. Therefore， it is necessary to continue implementing a comprehensive prevention and control strategy that emphasizes controlling the sources of infection and adopts tailored measures based on local conditions and precise policies.
ABSTRACT
OBJECTIVE@#To investigate the incidence trend and spatial clustering characteristics of scarlet fever in China from 2016 to 2020 to provide evidence for development of regional disease prevention and control strategies.@*METHODS@#The incidence data of scarlet fever in 31 provinces and municipalities in mainland China from 2016 to 2020 were obtained from the Chinese Health Statistics Yearbook and the Public Health Science Data Center led by the Chinese Center for Disease Control and Prevention.The three-dimensional spatial trend map of scarlet fever incidence in China was drawn using ArcGIS to determine the regional trend of scarlet fever incidence.GeoDa spatial autocorrelation analysis was used to explore the spatial aggregation of scarlet fever in China in recent years.@*RESULTS@#From 2016 to 2020, a total of 310 816 cases of scarlet fever were reported in 31 provinces, municipalities directly under the central government and autonomous regions, with an average annual incidence of 4.48/100 000.The reported incidence decreased from 4.32/100 000 in 2016 to 1.18/100 000 in 2020(Z=103.47, P < 0.001).The incidence of scarlet fever in China showed an obvious regional clustering from 2016 to 2019(Moran's I>0, P < 0.05), but was randomly distributed in 2020(Moran's I>0, P=0.16).The incidence of scarlet fever showed a U-shaped distribution in eastern and western regions of China, and increased gradually from the southern to northern regions.Inner Mongolia Autonomous Region and Hebei and Gansu provinces had the High-high (H-H) clusters of scarlet fever in China.@*CONCLUSION@#Scarlet fever still has a high incidence in China with an obvious spatial clustering.For the northern regions of China with H-H clusters of scarlet fever, the allocation of health resources and public health education dynamics should be strengthened, and local scarlet fever prevention and control policies should be made to contain the hotspots of scarlet fever.

Objective To analyze the mortality characteristics and trends and the cause-eliminated life expectancy of gastric cancer in Harbin City from 1987 to 2019. Methods Mortality data of residents with gastric cancer from 1987 to 2019 in Harbin was analyzed to describe the mortality characteristics and trends of gastric cancer. Abridged life table and cause-eliminated life table were applied to calculate life expectancy and cause-eliminated life expectancy. Average annual percentage change (AAPC) was calculated with Joinpoint 4.2 software to evaluate the trends of mortality and cause-eliminated life expectancy of gastric cancer. Results From 1987 to 2019, the crude mortality, ASMRC and ASMRW and the truncated rate (35-64) were 14.3/105, 10.9/105, 10.9/105, and 13.5/105, respectively. The ASMRC showed an obvious decreasing trend at an average annual rate of 2.9% from 1987 to 2019 (95%CI: -4.4%--1.4%). Significant decreasing trends were observed for males (AAPC=-3.0%, 95%CI: -4.4%--1.7%) and females (AAPC=-3.1%, 95%CI: -5.3%--0.9%). An obvious decreasing trend in the ASMRW was also observed. The truncated rate (35-64) showed a downward trend (AAPC=-2.8%, 95%CI: -3.1%--2.5%). The average life expectancy of residents from 1987 to 2019 in Harbin were 76.78 years (male: 74.41 years, female: 79.33 years). After eliminating the causes of death of gastric cancer, the life expectancy increased by 0.25 years (male: 0.31 years, female: 0.18 years). Significant decreasing trends were found in the proportion of gastric cancer in all malignant cancer cases (AAPC=-0.18%, 95%CI: -2.0%--1.7%). Conclusion The mortality of gastric cancer decreases gradually from 1987 to 2019 in Harbin. After eliminating the causes of death of gastric cancer, the life expectancy increases by 0.25 years. Therefore, prevention and control should be strengthened.

Objective@#To investigate the trend in incidence of stroke in Nanshan District, Shenzhen City from 2010 to 2021, so as to provide the evidence for formulating the integrated strategy for stroke control.@* Methods@#The data of stroke morbidity in Nanshan District from 2010 to 2021 were collected through Shenzhen Chronic Disease Prevention and Control Management System. The incidence of stroke was calculated, and standardized by the population of the Chinese Sixth National Census in 2010. The trends in stroke incidence were evaluated in Nanshan District from 2010 to 2021 using annual percent change (APC) and average annual percent change (AAPC), and gender-, age- and subtype-specific incidence of stroke was descriptively analyzed. @*Results@#A total of 30 377 cases with stroke were reported in Nanshan District from 2010 to 2021, with a crude incidence rate of 190.45/105 and a standardized incidence rate of 405.65/105. The crude incidence rate of stroke appeared a tendency towards a rise in Nanshan District from 2010 to 2021 (APC=5.38%, t=4.678, P=0.001), and a higher crude incidence rate of stroke was seen among men than among women (227.57/105 vs. 148.40/105; χ2=1 309.580, P<0.001). The incidence of stroke appeared a tendency towards a rise with age (χ2trend =435.717, P<0.001), and there was a tendency towards a rise in stroke incidence among residents under 40 years of age (APC=2.89%, t=2.538, P=0.029). The crude incidence of ischemic stroke was 151.24/105, which was higher than that of hemorrhagic stroke (39.21/105) (χ2=10 521.000, P<0.001). @*Conclusions@#The incidence of stroke appeared a tendency towards a rise in Nanshan District from 2010 to 2021, with ischemic stroke as the predominant subtype of stroke. Males and middle-aged and elderly residents should be given a high priority for stroke prevention and treatment.

Wenzhou has improved its environmental quality because of comprehensive environmental remediation; nevertheless, the semen quality of infertile males remains unclear. This study determined whether better environmental quality improved semen quality in this region. We recorded semen quality data from 22 962 infertile males from January 2014 to November 2019 at the Center for Reproductive Health of The First Affiliated Hospital of Wenzhou Medical University (Wenzhou, China). Patients were predominantly 30-35 years old (33.1%) and workers (82.0%), with high school education or lower (77.6%); more than a half of the patients (52.6%) were Wenzhou household registration; and most patients (77.5%) had abnormal semen quality. Patients who were older than 40 years and workers, and those with Wenzhou household registration, had significantly worse semen quality (all P < 0.05). From 2014 to 2019, progressive sperm motility, total sperm motility, and semen volume showed increasing linear trends in all patients (P = 0.021, 0.030, and 0.005, respectively), yet normal sperm morphology showed a linearly decreasing trend (P = 0.046). Sensitivity analyses for subgroups yielded similar results. In conclusion, the improvement of environmental quality and better function of the accessory glands are associated with progressive sperm motility, total sperm motility, and semen volume. Normal sperm morphology is influenced by occupational exposures and personal lifestyle and does not improve with environmental quality.

Objective: To analyze the trends of incidence and age change for global female breast cancer in different regions of the world according to the database from Cancer Incidence in Five Continents Time Trends (CI5plus) published by the International Association of Cancer Registries (IACR). Methods: The recorded annual female breast cancer (ICD-10: C50) incidence data and corresponding population at-risk data (1998-2012) were extracted from CI5plus published by IACR. The annual change percentage and average annual change percentage (AAPC) were calculated to examine the trends of incidence. The age-standardized mean age at diagnosis and proportion of incidence cases by age were calculated to analyze the relationship between incidence and age. Results: For crude incidence, except in Northern America, all other regions showed an upward trend, with Asia showing the most obvious upward trend (AAPC: 4.1%, 95% CI: 3.9%, 4.3%). For age-standardized incidence, in Asia, Latin America and Europe, the rising trends had slowed down, in Oceania and Africa, the trends began to be stable, and in Northern America, the trend showed a downward trend (APPC: -0.6%; 95% CI: -1.0%, -0.1%). The mean age at diagnosis were increased from 1998 to 2012 in Asia, Latin America, Oceania and Europe, with an annual increase of 0.12 years, 0.09 years, 0.04 years and 0.03 years, respectively. But after age-standardized, only Europe still kept increasing year by year, with an annual increase of 0.02 years, while Northern America showed a decreasing trend, with an annual decrease of about 0.03 years. Conclusions: From 1998 to 2012, the trends of incidence and age change for global female breast cancer vary in different regions of the world, and the global population aging is widespread, which affects the trend of the actual age change. Prevention and control strategies should be targeted at different age groups in different regions.

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.
ABSTRACT
ABSTRACT Background: Mucormycosis is a severe invasive fungal disease. During the coronavirus disease 2019 (COVID-19) pandemic, outbreaks have been reported worldwide, but epidemiological studies are still scarce in Brazil. Methods: We conducted a time-series cohort hospitalization study (2010-2021) in southeastern Brazil. Results: There were 311 cases (85 during the pandemic), with significant (P < 0.05) involvement of patients older than 40 years (84%), white patients (78%), rhinocerebral site (63%), and São Paulo State residents (84%). Conclusions: Mucormycosis hospitalizations were highly prevalent. Further studies are needed to assess the burden of COVID-19 on mucormycosis in Brazil.
ABSTRACT
Guided by the principle of leaving no one behind by improving equitable access and use of new and existing vaccines, the Immunization Agenda 2030 aims, among other things, to halve the incidence of "zero-dose" at the national level. This study aimed at studying the tends of the prevalence of "zerodose" children from 2000 to 2017 and making predictions for 2030. The study consisted of secondary data analyses from the Multiple Indicator Cluster Surveys (MICS) conducted in Togo. The study population consisted of children aged 12-23 months surveyed during MICS2 in 2000, MICS3 in 2006, MICS4 in 2010 and MICS6 in 2017. The dependent variable was the "zero-dose" vaccination status (1=Yes vs 0=No). The explanatory variables were related to the child, mother, household and environment. The study generated the overall annual percentage changes (APC) and by the independent variables. As a result, the prevalence of children with "zero-dose" expected for 2030 was estimated using Excel 2013 and Stata 16.0 software. In total, 636, 864, 916 and 952 children aged 12-23 months were included for MICS2, MICS3, MICS4 and MICS7, respectively. The prevalence of "zerodose" children decreased from 37.15% in 2000 to 31.72% in 2006, then 30.10% in 2010 and 26.86% in 2017, with an overall APC= - 1.89%. The highest relative annual decrease was from 2000 to 2006. If the historical rate of decrease remains unchanged, we predict that percentage of "zero-dose" children aged 12-23 months will be 20.96% in 2030, with a decrease of 22% compared to 2017, against a target of 50%. We suggest that strengthening strategies to increase full immunization coverage of children will contribute to reducing the percentage of zero dose children. A prerequisite will be a better understanding of the predictors of the "zero-dose" phenomenon in children
