RESUMEN
Objective: To investigate the characteristics and trends of spontaneous subarachnoid hemorrhage (SAH) in Shandong province. Methods: In this study, SAH incidence data of residents from 2012 to 2021 were collected from the chronic disease monitoring information management system of Shandong province, including the basic information of outpatient, emergency or inpatient cases and out-of-hospital deaths (name, gender, ID number, address, etc.) and disease diagnosis information (disease diagnosis, date of onset, date of diagnosis, etc.). The crude incidence rate and age-standardized incidence rate were used as indicators to describe the incidence of SAH in different gender, age groups and regions (urban and rural areas). Joinpoint regression was used to analyze the variation of incidence rate and age by year. The rate difference decomposition method was used to estimate the contribution of population aging to the increase of SAH incidence. Global and local spatial autocorrelation analysis was performed using DeoDa 1.12 software. Results: From 2012 to 2021, a total of 11 629 cases of SAH were reported from 19 provincial monitoring sites in Shandong province. Among them, 54.11% (6 293 cases) were female and 91.87% (10 684 cases) were≥45 years old. The reported crude incidence rate increased from 5.26/100 000 to 9.50/100 000, with an average annual increase of 7.75% (Ztrend=7.30, Ptrend<0.001), and the standardized incidence rate also showed an upward trend (Ztrend=3.92, Ptrend=0.004). The crude incidence rate of women was higher than that of men in all years (all P values<0.05), and the standardized incidence rate of women was higher than that of men in all years except in 2012 and 2021 (all P values<0.05). In 2012, the crude incidence and standardized incidence of urban residents were lower than those in rural areas (P<0.05); from 2013 to 2017, the urban incidence was higher than that in rural areas; and after 2018, the rural incidence exceeded the urban incidence again (all P values<0.05). The median age of onset of SAH increased from 61.9 years in 2012 to 67.2 years in 2021. The age of onset of SAH in men was lower than that in women in all years (all P<0.05), and there was no significant difference between urban and rural residents in most years (P>0.05). The incidence of SAH increased with age (Ptrend<0.001), with a low incidence reported in residents aged<45 years and a rapid increase in residents aged≥45 years. According to the seasonal decomposition, the incidence of SAH had three small peaks in January, March to May and October to November. From 2013 to 2021, the contribution of aging population to the increase of crude incidence of SAH increased from 27.86% to 43.68%. The global spatial autocorrelation analysis showed that the incidence of SAH was in an obvious spatial aggregation distribution (Moran's I>0, P<0.05). Local spatial autocorrelation analysis showed that the counties with high incidence were mainly concentrated in Dezhou City in northwest Shandong Province and Heze city in southwest Shandong province. Conclusions: The crude incidence rate of SAH in Shandong province is increasing, with spatial clustering and seasonal clustering. Residents aged 45 years and older, female residents, and rural residents are at high risk of developing SAH, so targeted prevention and control measures should be taken for high-incidence seasons, high-risk groups, and high-incidence clustered areas.

Objective: To analyze the trend of incidence and mortality of thyroid cancer and estimate its age-period-cohort effect in Shandong Province from 2012 to 2022. Methods: The Joinpoint regression was used to analyze the trend of incidence and mortality of thyroid cancer and calculate the average annual percentage change (AAPC) based on the data on thyroid cancer from 2012 to 2022. The age-period-cohort model was used to analyze the age-effect, time-effect and cohort-effect of thyroid cancer risk in the population aged over 20 years. Results: From 2012 to 2022, the incidence of thyroid cancer in Shandong province showed a significant upward trend, with an AAPC of 21.68% (95%CI: 19.14%-24.27%, P<0.001). The incidence of females was higher than that of males, and the incidence of urban areas was higher than that of rural areas. The trend of thyroid cancer mortality was relatively stable with an AAPC of -3.04% (95%CI:-8.81%-3.09%, P=0.323). The age effect of incidence increased with age before 60 years old and decreased with age after 60 years old. The incidence peaked in the age group of 55-59. The period effect increased with time. The cohort effect showed that the cohort born before 1957 had a downward trend over time, while the cohort born after 1957 had an upward trend. Conclusion: The incidence of thyroid cancer in Shandong shows a rising trend from 2012 to 2022. Age is an important factor affecting the risk of thyroid cancer. The mortality of thyroid cancer remains stable.

Objective: To study the complete genome characterization of Human Astrovirus (HAstV) in Shandong Province. Methods: Stool samples from acute flaccid paralysis (AFP) surveillance in Shandong Province from 2020 to 2022 were collected, and HAstV nucleic acid was examined by real-time quantitative PCR (qPCR). Next-generation sequencing (NGS) was conducted for the positive samples to obtain complete genome sequences and identify the genotype. Homology comparison and phylogenetic analysis were performed by using BioEdit and Mega software. Results: A total of 667 samples were examined by qPCR, of which 14 were HAstV-positive (2.1%), including HAstV-1 (n=6), MLB1 (n=6), MLB2 (n=1), and VA2 (n=1). The complete genome sequences were obtained from 11 samples. The six HAstV-1 sequences of this study had 98.2% to 99.9% nt similarities with each other and 87.6% to 98.6% with those from other regions. The four MLB1 sequences of this study had 99.1% to 99.9% nt similarities with each other and 92.2% to 99.4% with those from other regions. The VA2 sequence of this study had 96.0% to 96.3% nt similarities with those from other regions. Phylogenetic analysis based on ORF2 region showed that the local HAstV-1 sequences were most closely related to Japanese strains, and had distinct topology with phylogenies based on ORF1a and ORF1b regions. Conclusion: The complete genome sequences of 11 HAstV strains are obtained, and the VA2 complete genome is found.

Objective: To analyze the epidemiological characteristics and clinical features of pertussis cases reported in Shandong Province of China. Methods: Data on pertussis cases in Shandong Province from 2007 to 2022 were collected from China Information System for Disease Control and Prevention. At the same time, some case information was collected from the database of notifiable pertussis in Shandong Province from 2007 to 2022. The distribution characteristics and clinical features of pertussis were analyzed. A spatial distribution map of pertussis cases in Shandong Province was drawn. Results: A total of 26 122 pertussis cases were reported in Shandong Province during 2007-2022, with an annual incidence rate ranging from 0.11 to 5.77 cases per 100 000 people. Cases occurred throughout the whole year, with a seasonal peak occurring in spring and summer, especially in July and August. In recent years, reported cases were mainly distributed in the central and western regions of Shandong Province, with fewer cases in the eastern region. The hot spots of the disease shifted from Heze and Dezhou City in 2007-2013 to Jinan and Tai'an city in 2014-2022. The age range of onset was from 1 day to 93 years old. The proportion of cases with age≤1 year was the largest (41.81%, 10 922/26 122), and the proportion of cases aged 0-6 months decreased from 32.21% (67/208)-55.67% (157/282) within the period of 2007 to 2013 to 16.78% (883/5 263)-41.97% (444/1 058) within the period of 2014 to 2022, with a statistically significant trend (χ² trend=670.01, P<0.001). There were 13 682 male cases and 12 440 female cases, with a male-female ratio of 1.10â¶1. The male-female ratio was 1.45â¶1 (806â¶556) from 2007 to 2013 and 1.08â¶1 (12 876â¶11 884) from 2014 to 2022. The proportion of women increased from 42.31% (88/208) in 2007 to 47.84% (2 518/5 263) in 2022, and with a significant trend (χ² trend=22.25, P<0.001). In pertussis cases, the proportions of scattered children, kindergarten children and students were 71.38% (18 645/26 122), 15.13% (3 951/26 122), and 11.60% (3 031/26 122), respectively. The top five clinical symptoms of pertussis cases were paroxysmal spasmodic cough (86.33%, 21 411 cases), flushing (39.61%, 9 824 cases), restless sleep (34.51%, 8 558 cases), fever (30.80%, 7 638 cases), and crowing (27.53%, 6 829 cases). Among 24 802 cases, there were 15 542 cases (62.66%) with a history of immunization against pertussis vaccine. Conclusion: From 2007 to 2022, the incidence rate of pertussis cases in Shandong Province shows an upward trend, with the majority being young children, and the clinical symptoms are relatively typical.

In order to understand the knowledge, attitude and practice (KAP) of vaccination against influenza, pneumonia, human papillomavirus (HPV), herpes zoster (HZ), COVID-19, and hepatitis B among staff of vaccination units in Shandong Province, a sample survey was conducted among 797 staffs of adult vaccination units in 12 counties (cities and districts) of Shandong Province from August to September 2022. The results showed that the respondents had the highest total score of knowledge and attitude for the COVID-19 vaccine, with the M (Q1, Q3) of 23 (20, 25) and 10 (10, 10), respectively, and had the lowest score of knowledge and attitude for the herpes zoster vaccine, with the M (Q1, Q3) of 19 (15, 22) and 8 (8, 10), respectively. The vaccine-related knowledge point"vaccine applicable population"had the highest score, with the M (Q1,Q3) of 26 (23, 30). The "contraindications/adverse reactions" and "adverse reaction management" had the lowest score, with the M (Q1, Q3) of 24 (20, 29) and 24 (20, 28), respectively. About 89.71% of respondents received one adult vaccine within two years at least. The principal driver for vaccination of 53.58% of recipients was their understanding of vaccines, which was"it was necessary to receive the vaccine". About 66.00% of respondents who had not received any adult vaccine in the past two years had insufficient awareness of the necessity of vaccination and believed that they were in good health and did not need to receive it. In summary, the staff of adult vaccination units in Shandong Province have a poor understanding of the herpes zoster vaccine in terms of vaccines and a relatively poor understanding of"contraindications/adverse reaction and management"in adult vaccination knowledge points.

Objective: To understand the knowledge, attitude and behavior of adult residents on influenza, pneumococcus, human papillomavirus (HPV), herpes zoster (HZ), COVID-19, hepatitis B and rabies vaccination in Shandong Province. Methods: From August to September 2022, a multi-stage stratified random sampling method was used to investigate community-dwelling residents aged 18 years old and above in 12 counties (cities and districts) of Shandong Province. A questionnaire survey was used to collect the basic information of the respondents, such as knowledge, attitude and vaccination behavior of influenza, pneumococcus, HPV, HZ, COVID-19, hepatitis B and rabies vaccine. Analysis of variance was used to compare the differences in the respondents' knowledge and attitude scores of different vaccines. The Chi-square test was conducted to compare the differences in vaccination reasons among different characteristics, and a logistic regression model was used to analyze the influencing factors of vaccination behavior. Results: The median age (Q1, Q3) of the 2 754 respondents was 39 (29, 57) years ranging from 18 to 94 years, with a number of 1 234 (44.81%) males. The average score of the respondents' understanding of various knowledge about adult vaccines was less than 4 points, with the highest score for understanding which diseases can be prevented by adult vaccines. The average score of consent and necessity for adult vaccines to prevent diseases was greater than 3.6 points. In terms of knowledge demand and trust in information channels, there was a high level of trust in the recommendations of vaccination outpatient staff and clinical doctors [with scores of (4.15±0.79) and (4.02±0.80), respectively]. The highest demand for information on vaccination safety knowledge was (4.18±0.84) points. In recent two years, 52.11% of the population had been vaccinated with other vaccines in addition to the COVID-19 vaccine and rabies vaccine, and 45.44% of the population felt it was necessary to be vaccinated through media publicity. Women, age growth, high education level, and high-income level were the promoting factors for adopting vaccination behavior. Conclusion: Adult residents in Shandong Province have a basic understanding and supportive attitude towards vaccination, but the vaccination behavior rate is still relatively low, with significant differences in sex, age, education level, and income level. It is necessary to further increase efforts in the breadth and depth of adult vaccination promotion and education, as well as promotion strategies targeting different populations.

Objective: To understand the setting of adult vaccination clinics and the situation of adult vaccination in Shandong province, and provide the date basis for the construction and development of adult vaccination clinics in Shandong province. Methods: Multi-stage stratified cluster random sampling was used to survey the settings, personnel allocation, operation status, and adult vaccination status of child-adult vaccination clinics and adult vaccination clinics. A random sampling survey was conducted for hydrophobia vaccination clinics in 12 counties (cities, districts) of Shandong province. The settings and vaccination status of different types of adult vaccination clinics were compared and analyzed using analysis of variance or χ2-test. Results: Among the investigated counties (cities, districts), the child-adult vaccination clinics, the adult vaccination clinics, and the hydrophobia vaccination clinics accounted for 59.51%, 7.97% and 32.52%, respectively. The construction model could be divided into three models: child-adult vaccination clinic model, child-adult and hydrophobia vaccination clinic model, child-adult, adult and hydrophobia vaccination clinic model. The child-adult vaccination clinics had been set up for a long time (≥3 years accounted for 94.33%) and were set up by public primary medical institutions (public institutions accounted for 93.81% and primary institutions accounted for 92.78%). Each vaccination clinic was equipped with full-time and part-time staff of (3.19±3.01) and (3.72±4.32). The adult vaccination clinics had been set up for a short time (≥3 years accounted for 94.33%) and were set up by public/private primary/secondary medical institutions in urban areas (urban areas accounted for 100%, primary institutions accounted for 69.23%, and private institutions accounted for 57.69%). Each vaccination clinic was equipped with full-time and part-time staff of (2.46±2.87) and (3.08±3.53). The coverage of influenza vaccine (InfV), human papillomavirus vaccine (HPV) and hepatitis B vaccine (Hep B) reached 100%, 98.45% and 97.42% in children-adult vaccination clinics, and 88.46%, 84.62% and 73.08% in adult vaccination clinics, respectively. The hydrophobia vaccination clinics only provided rabies vaccine for human use (RabV) and tetanus vaccine (TV) vaccination simultaneously. A total of 819.8 thousand doses of adult vaccines were administered in 2021. The adult inoculation doses of RabV, lnfV and HPV accounted for 42.60%, 27.47% and 17.54% of the total inoculation doses, respectively. The inoculation doses of InfV, HPV and RabV accounted for 49.33%, 21.97% and 13.80% of child-adult vaccination clinics, respectively. The inoculation doses of HPV, HepB and RabV accounted for 49.36%, 15.40% and 14.71% of adult vaccination clinics, respectively. The proportion of RabV reached 94.44% in the hydrophobia vaccination clinics alone. Conclusion: Adult vaccination is at the initial stage in Shandong province. The children's vaccination clinic is mainly responsible for adult vaccination. The variety of adult vaccines is relatively concentrated, and the adult vaccination rate is lower. The construction and publicity of adult vaccination should be further strengthened.

Objective: To analyze the utilization of adult vaccination among people aged 18 and above in Shandong Province from 2018 to 2022. Methods: Data on vaccination units in 2022 and individual cases of vaccination information for people aged 18 and above were extracted from the Shandong Immunization Information System. A descriptive analysis was conducted on the distribution of adult vaccination units and adult vaccination varieties. The total vaccination amount and vaccination rate were calculated. Results: By the end of 2022, there were 3 948 vaccination units providing adult vaccination in Shandong Province, with 0.36 adult vaccination clinics per 10 000 people. Adult vaccination including RabV(rabies vaccine for human use), InfV(influenza vaccine), HPV(human papillomavirus), HepB(hepatitis B vaccine), PPV23(23-valent pneumococcal polysaccharide vaccine), MenACYW135(meningococcal polysaccharide vaccine group ACYW135), MMR(measles, mumps and rubella combined attenuated live vaccine), HEV(hepatitise E vaccine), RZV(recombinant zoster vaccine), TV(tetanus vaccine) and HF(haemorrhagic fever with renal syndrome vaccine) vaccines were administered, with a cumulative dose of 40.056 9 million and an average of 0.1 doses per person per year from 2018 to 2022. The top three vaccines were RabV, InfV and HPV, accounting for 31.48%, 22.57%, and 15.93% of the total vaccination amount, respectively. The annual vaccination dose for adults increased from 3.477 3 million in 2018 to 13.308 6 million in 2022, with an average annual growth rate of 56.55%. The cumulative 5-year doses of RabV and TV were 15.90 doses per 100 people and 0.21 doses per 100 people. The average annual vaccination rate of InfV was 2.28%. The cumulative full vaccination rates of HPV, HepB, PPV23 and RZV were 12.44%, 1.61%, 0.52% and 0.17%, respectively. The cumulative 5-year doses of RabV and TV were 29.19 doses per 100 people and 0.43 doses per 100 people in the age group of 20 to<30 years old. The vaccination rates of InfV and PPV23 were 9.08% and 1.27% in the age group of 70 to<80 years old. The vaccination rate of RZV was 0.11% in the age group of 50 to<60 years old. The HPV vaccination rate was 18.09% in the age group of 20 to<30 years old, and the HepB, MenACYW135, MMR and HEV vaccination rates were 6.21%, 9.55%, 2.65%, and 2.83% in the 18-19 age group, respectively. Conclusion: There are relatively few types of adult vaccination in Shandong Province, with narrow coverage and low vaccination rates.

Objective: To investigate the operation of children's vaccination clinics in Shandong Province, simulate the efficiency of vaccination capacity utilization, and explore the feasibility of carrying out adult vaccination in children's vaccination clinics. Methods: Using the extreme hypothesis method to determine the maximum vaccination capacity of children's vaccination clinics. Based on on-site surveys, population, and vaccination rate data, simulation parameters were determined, and the simulation method was used to simulate the utilization efficiency of vaccination capacity in different scenarios of children's vaccination clinics. Results: There were 2 654 children's vaccination clinics by the end of 2021 in Shandong province. There was (6.93±4.02) staff per vaccination clinic, with an average opening day of (4.16±2.19) days per week. In the scenario of only vaccinating children, the utilization efficiency of vaccination capacity during the non-influenza vaccination season was only 30.74% and 14.07% in urban and rural vaccination clinics, respectively. During the influenza vaccination season, the utilization efficiency of the vaccination capacity of urban vaccination clinics reached 49.26% when the child influenza vaccination rate reached 20%. In the scenario of simultaneous vaccination of children and adults, the utilization efficiency of vaccination capacity during the non-influenza vaccination season was 41.48% and 18.52% in urban and rural vaccination clinics, respectively. During the influenza vaccination season, the utilization efficiency of vaccination capacity in urban vaccination clinics reached 51.47% when the influenza vaccination rate of the entire population reached 3%. The utilization efficiency of vaccination capacity in rural vaccination clinics reached 52.44% when the influenza vaccination rate of the entire population reached 20%. Conclusion: The accessibility of children's vaccination is good in Shandong province, and the utilization efficiency of vaccination capacity can meet the current vaccination needs of children and adults. The vaccination capacity in urban areas needs to be strengthened to meet the growing vaccination needs of children and adults in the future.
