Objective:To explore the influencing factors of AIDS-related deaths among HIV-infected patients in Shandong Province, to help reduce the risk of death and prolong survival time.Methods:The study population was HIV-infected patients in Shandong Province from 2017-2021, and Cox proportional hazards regression model was used to analyze the influencing factors of AIDS-related deaths and deaths within one year of confirmation.Results:Among 14 700 HIV- infected patients reported in Shandong Province in 2017-2021, 351 AIDS-related deaths occurred, accounting for 2.4% (351/14 700). The results of multifactorial Cox proportional hazards regression model analysis showed that the risk factors for AIDS-related deaths among HIV-infected patients included education level of junior high school, high school, and secondary school (a HR=1.37, 95% CI:1.01-1.84), sample source from healthcare institutions (a HR=1.61, 95% CI:1.22-2.12), duration of disease in AIDS stage (a HR=9.86,95% CI:6.86-14.19), baseline CD4 +T lymphocytes (CD4) undetected (a HR=3.93, 95% CI:2.69-5.75), duration of antiviral treatment (ART) <6 months (a HR=3.46, 95% CI:2.42-4.93) and no ART (a HR=1.45, 95% CI:1.02-2.07), final CD4 <200 cells/μl (a HR=3.51, 95% CI:2.18-5.65) and final CD4 undetected (a HR=10.58, 95% CI:6.15-18.19), and final viral load (VL) values of 50-999 copies/ml,≥1 000 copies/ml and undetected (a HR=2.59, 95% CI:1.07-6.26; a HR=9.50, 95% CI:5.60-16.12; a HR=15.33, 95% CI:8.91-26.36). Factors with higher risk of AIDS-related deaths within one year of confirmation of HIV-infected patients included samples originating from healthcare facilities (a HR=1.68, 95% CI: 1.19-2.36), AIDS stage of disease (a HR=10.60, 95% CI:7.13-15.75), baseline CD4 undetected (a HR=3.71, 95% CI:2.34-5.90), duration of ART <6 months (a HR=4.30, 95% CI:2.85-6.49) and no ART (a HR=2.05, 95% CI:1.35-3.13), final CD4 <200 cells/μl (a HR=5.45,95% CI:2.04-14.60) and final CD4 undetected (a HR=20.95, 95% CI: 7.69- 57.04), and final VL values of 50-999 copies/ml, ≥1 000 copies/ml and undetected (a HR=15.21, 95% CI: 2.54-91.21; a HR=42.93, 95% CI:9.64-191.20; a HR=61.35, 95% CI:13.85-271.77). Conclusions:Expanding the coverage of testing, promoting early detection and treatment, strengthening regular follow-up and the test of HIV-infected patients, grasping the progress of the disease to provide accurate management and treatment are important for reducing the disease mortality rate and prolonging the survival time of HIV-infected patients.

Objective:To observe the occurrence of medication deviation in elderly patients with chronic diseases, and analyze the related factors leading to its occurrence.Methods:Convenience sampling method was used to select 164 elderly patients with chronic diseases who were discharged from the hospital after treatment from April 2021 to March 2022 as the study subjects.The pharmacists reviewed the patient's discharge medication and counted the occurrence of medication deviation.The patients were divided into the occurrence group and the non-occurrence group, and the relevant data of the two groups and their attending physicians were analyzed and compared. Logistic regression analysis was used to test the influencing factors of medication deviation in elderly patients with chronic diseases. Results:Medication deviation were identified in 110 of the 164 patients, and the incidence of medication deviation was 67.1%.Compared with the non-occurrence group, the number of diseases, discharge prescriptions of patients were more, the differences were statistically significant( Z=2.552, t=3.063, both P<0.05). The age of attending physicians in the occurrence group were younger, and their working years were shorter, professional title was lower compared with those in the non-occurrence group( Z=3.754, 3.713, Z=2.016, P<0.05 for all); Logistic regression analysis showed that the number of diseases and discharge prescriptions were the risk factors for medication deviation in elderly patients with chronic diseases( OR=1.260, 1.227, both P<0.05); older age and longer working years of attending physicians were the protective factors for medication deviation( OR=0.925, 0.930, both P<0.05). Conclusions:The incidence of medication deviation in elderly patients with chronic diseases in our hospital is high.Number of chronic diseases, discharge prescriptions, younger age and relatively shorter working years of attending physicians may lead to medication deviation.

Objective:To compare the characteristics of MSM with different types of primary sexual partners and to analyze the factors associated with MSM not being tested for HIV in the last six months.Methods:MSM were recruited in nine cities of Shandong Province from April to July 2021, and face-to-face questionnaires were conducted to collect information on sociodemographic characteristics, high-risk behaviors, and HIV testing of MSM. Blood samples were taken for serological tests of HIV and syphilis antibodies.Results:A total of 3 008 men who had anal sex with men in the last six months were divided into three groups according to the type of primary sexual partner in the last six months: the fixed sexual partner group (36.83%, 1 108/3 008), the commercial sexual partner group (3.06%, 92/3 008), and casual sexual partner group (60.11%, 1 808/3 008). There were statistically significant differences in the distribution of age, local residence time, education level, the primary place to find male sexual partners, use of new-type drugs in the last six months, consistent condom use every time during same-sex anal sex in the last six months, group sex in the last six months, no HIV testing in the last six months, having had a sexually transmitted disease in the last year, receiving peer education in the last year, and frequency of syphilis testing in the last year among different groups ( P<0.05). Multivariable logistic regression analysis showed that related factors of not being tested for HIV in the last six months in MSM were those aged less than 30 years old (a OR=1.39, 95% CI: 1.06-1.83), married/cohabiting (a OR=1.74, 95% CI: 1.39-2.16), high school education or less (a OR=1.39, 95% CI: 1.15-1.67), had not used new-type drugs in the last six months (a OR=2.27, 95% CI: 1.89-2.71), had not received peer education in the last year (a OR=1.59, 95% CI: 1.28-1.98), had never been tested for syphilis (a OR=11.30, 95% CI: 8.15-15.66), had not been tested in the last year but had been previously tested for syphilis (a OR=5.65, 95% CI: 4.19-7.62), the type of primary sexual partner in the last six months being a commercial sexual partner (a OR=1.80, 95% CI: 1.01-3.20), and the type of primary sexual partner in the last six months being a casual sexual partner (a OR=1.50, 95% CI: 1.26-1.80). Conclusions:The characteristics of MSM with different types of primary sexual partners are different, and the proportion of HIV testing still needs to be improved. In the future, we should make full use of the Internet and peer education to expand the coverage of HIV testing for MSM, targeting the characteristics of MSM with different types of primary sexual partners.

The diagnosis of food allergy in children is one hotspot attracting people′s attention in recent years.The incidence of it shows an increasing trend which exposes problems in the understanding of children′s food allergy in China, especially in the misdiagnosis and missed diagnosis.To further standardize the diagnosis and treatment of food allergy in children, based on the current domestic, foreign guidelines and relevant research evidence, the guideline recommends 16 clinical hot-button issues in the 4 aspects of diagnosis, treatment, prognosis, and prevention.Finally, a diagnosis flowchart has been formulated.The guideline aims to improve the standard diagnosis and treatment of food allergies in children in China.

Objective:To analyze the status of first viral load (VL) suppression for newly diagnosed HIV/AIDS on antiretroviral therapy (ART) from 2014 to 2016 in Shandong province, to provide theoretical evidence for improvement of ART effectiveness.Methods:Based on a retrospective cohort study, logistic regression model was used to identify influencing factors about VL suppression.Results:There were 4 833 newly diagnosed HIV/AIDS cases who received ART from 2014 to 2016 in Shandong province, and 3 449 cases achieved VL suppression at the first VL testing. The rate of first VL suppression was 71.36%. The possibilities of first VL suppression among patients on ART with education at junior high school, junior college and above were higher than those with education at primary school and below, with OR values at 1.75 and 2.00, separately. The possibilities of first VL suppression for patients treated at medical institutions was higher than those by CDC, with OR value 1.29. The possibilities of first VL suppression among patients whose CD4 count level at 201-350, 351-500 and ≥501 cells/μl were higher than that of the patients whose CD4 count level at ≤200 cells/μl, with OR values at 2.36, 2.11 and 2.66, respectively. The possibilities of first VL suppression among patients who missed doses was lower than those who did not miss doses, with OR value at 0.55. All the Pvalues for the above comparisons was <0.05. Conclusions:The suppression of viral load for HIV/AIDS on ART was influenced by culture level, CD4 count level at the entry of ART, treatment institutions and adherence to the therapy. Earlier diagnosis, treatment services provided by medical institutions and improvement of drug adherence can enhance ART effectiveness.

Objective: To analyze the epidemiological characteristics of HIV/AIDS infected students in Shandong Province, to provide a basis for the prevention and control of AIDS transmission in the student population. Methods: All 863 HIV/AIDS students cases during 2010-2019 were collected in Shandong Province. Epidemiological characteristics was described and the trends in the 10 years since 2010 was analyzed. Results: These 863 HIV/AIDS students were mainly transmitted through homosexual sex (763 cases, 88.41%), and the samples were mainly from voluntary consultation testing (433 cases, 50.17%). From 2010 to 2019, the proportion of student cases in the total number of cases showed an increasing trend ( χ 2 trend =30.21, P <0.01). Among them, the proportion of homosexual transmission cases increased year by year ( χ 2 trend =6.35, P =0.01), the proportion of cases aged 18-22 years increased year by year ( χ 2 trend =6.10, P =0.01), the proportion of cases with college degree or above increased year by year ( χ 2 trend =4.26, P =0.04). At present, voluntary consultation testing were the main source.There was no significant difference between the years of sample sources ( χ 2 trend =2.97, P =0.09). Conclusion The report number of students in Shandong Province are on the rise in recent years, especially those infected by same sex transmission, mainly with high education background, which calls for targeted strategies and intervention measures.

Objective:To analyze the timeliness and influencing factors of antiretroviral treatment (ART) among HIV/AIDS patients from 2017 to 2019 in Shandong province.Methods:Data were collected from the Chinese HIV/AIDS Comprehensive Response Information Management System, HIV/AIDS cases enrolled in antiretroviral therapy, from January 1, 2017 to December 31, 2019, ≥15 years of age and from the mainland of China were the subjects of the study. The general demographic characteristics (gender, age, ethnicity, education level, marital status, etc), infection routes, sample sources, date of diagnosis, baseline CD4+ T cell level, and clinical stage and other information were collected from the database. Univariate analysis was conducted for the timeliness of ART of the subjects by Chi square test, and the influencing factors associated with timeliness of ART were analyzed by binary non-conditional Logistic regression.Results:Among the 7 425 cases of HIV/AIDS, 6 813(91.8%) were male, 5 236(70.5%) had homosexual transmission, the age at the ART initiation was(36.05±12.51)years. The proportion of timeliness of ART within 30 d increased from 55.9% (1145/2050) in 2017 to 65.3% (1821/2789) in 2019. The possibility of timeliness of ART among HIV/AIDS who were married or cohabiting, education of high school and above were higher, with OR values at 1.136, 1.299. The possibility of timeliness of ART among HIV/AIDS cases whose domicile place is outside Shandong province were lower, with OR values at 0.664. The possibility of timeliness of ART in group of HIV/AIDS aging≥55, 45~54 and 35~44 years old were higher than that in 15~24 years old, with OR values at 1.530, 1.505 and 1.394. The possibility of timeliness of ART among the heterosexuals were lower than that of homosexuals, with OR values at 0.803. The possibility of timeliness of ART is lower for cases in places of detention centers than cases from volunteer testing and counseling, with OR values at 0.204. The possibility of timeliness of ART among HIV/AIDS cases whose CD4+ T lymphocyte at >500 cells/μL were lower than that of the cases whose CD4+ T lymphocyte at≤500 cells/μl, with OR values at 0.545. Patients without symptoms at baseline were less likely to receive prompt treatment than those with clinical symptoms, with OR values at 0.727. Patients with baseline clinical staging of stage Ⅳ, period of HIV/AIDS treatment with timeliness was longer than the cases with baseline clinical stages ofⅠ, Ⅱ, Ⅲ, with OR values at 1.307. Conclusions:The proportion of timeliness of ART increased from 2017 to 2019. Marital status, educational level, age, sample source, infection routes, baseline clinical stage, and CD4+ T lymphocyte levels were associated with the timeliness of ART.

Objective:To understand the use of drug and its related factors among men who have sex with men, and to provide reference for the development of reasonable intervention measures.Methods:MSM was recruited from Jinan and Qingdao by means of on-site and internet recruiting from March to June in 2016. Anonymous questionnaires were conducted and HIV and syphilis serological tests were performed. The questionnaire included the general situation, sexual behavior, HIV related services and so on. Multi-factor unconditioned logistic regression model was used to explore related factors about rush poppers use.Results:The rush poppers use rate of 901 MSM was 30.1%（271/901）, the age was (29.3±8.1) years, the HIV infection rate was 4.6% (41/901) and the syphilis infection rate was 8.7% (78/901). Multivariate analysis showed that compared with those who were>25 years old, the OR (95% CI) of those who were ≤ 25 years old was 1.571 (1.110-2.224); compared with the number of anal sexual behavior was<2 times in the last week, the OR (95% CI) of those whose number of anal sexual behavior was ≥2 times was 2.991 (1.100-8.132); compared with those who had not received peer education services in the last year, the OR (95% CI) of those who received peer education services was 13.651 (7.239-25.742). Conclusion:Rush poppers are very popular in the MSM crowd, and those who aged less than 25 years old, who had anal sex more than twice in the past week, and who had received peer education services were more likely to use rush poppers. We should carry out targeted interventions according to the characteristics.

Objective:To explore the impact of achievement of the "90-90-90" goals on reductions in HIV incidence in Shandong province.Methods:An algebraic method was developed to link new HIV infections and the "90-90-90" goals in Shandong province. The risk estimation equation was used to analyze the effect of achievement of the "90-90-90" goals on reductions of HIV incidence, and explore the impact of application of antiviral therapy based prevention and control strategy on reduction of new HIV infections.Results:If "90-90-90" goals were achieved in 2020 in Shandong compared with annual new HIV infections in 2010, the percentage of reduction would be 17.27%, 35.99% and 67.55% respectively when transmission rate decreased by 26.00%, 53.00% and 96.00% respectively. Compared with 2017, when the transmission rate decreased by 53.00%, the annual new HIV infections would has a decrease of 10.10% if the rates of diagnosis and ART reached 90.00%; the annual new HIV infections would has a decrease of 20.80% if the rates of diagnosis and viral suppression reached 90.00%; the annual new HIV infections would has a decrease of 12.29% if the rates of ART and viral suppression reached 90.00%.Conclusions:HIV incidence would decrease with the achievement of "90-90-90" goals in Shandong. Compared with the improvement of ART, the improvement in diagnosis of HIV infection and viral suppression would result in more rapid decrease of new HIV infections. Besides expanding ART coverage, more attention should be paid to the strengthening of the diagnosis of HIV infection and viral suppression in Shandong.

Objective:To understand the relationship between new-type drug use and high risk behavior in men who have sex with men (MSM) in Shandong province.Methods:Cross-sectional surveys was conducted to collect the information about demographics, sexual and drug use behaviors of MSM and HIV-related services in MSM in three sentinel surveillance sites in Shandong from April to July in 2019. Blood samples were taken from the MSM for serological tests of HIV antibody and syphilis antibody.Results:A total of 1 203 MSM were included in this study. The average age of the MSM was 30.2±8.9 years. Among these MSM, 67.7 % (815) were unmarried; 66.9 % (805) had education level of college or above; 62.2 % (721/1 160) had unprotected sex behaviors and 16.3 % (189/1 160) had group sex behavior in the past six months and 54.2 % (652/1 203) ever used new-type drugs. HIV infection and syphilis prevalence rates were 3.1 % (37/1 203) and 4.7 % (56/1 203), respectively. Multivariable logistic analysis indicated that MSM who had unprotected anal sex in the past six months were more likely to be from Qingdao (a OR=1.59, 95 %CI:1.13-2.23), with education level of high school or below (a OR=1.61, 95 %CI: 1.20-2.16), with male sex partners from bars/dance halls or other venues (a OR=1.69, 95 %CI: 1.06-2.69), with HIV knowledge awareness score <6 (a OR=1.55, 95 %CI: 1.01-2.37), with ≥2 sex partner in the past week (a OR=1.48, 95 %CI: 1.12-1.95), to have group sex behaviors in the past six months (a OR=2.43, 95 %CI:1.61-3.67) and to use new-type drugs (a OR=1.46, 95 %CI: 1.11-1.91). MSM who had group sex were more likely to have following features: being from Qingdao (a OR=2.21, 95 %CI: 1.45-3.38), non-Shandong residents (a OR=2.13, 95 %CI: 1.28-3.55), HIV knowledge awareness score ≥6 (a OR=3.11, 95 %CI: 1.55-6.25), ever having unprotected anal sex behaviors (a OR=2.60, 95 %CI: 1.71-3.96) and ever having male commercial sex (a OR=3.38, 95 %CI: 1.92-5.95) in the past six months, ever using new-type drugs (a OR=2.71, 95 %CI: 1.82-4.04), and never having HIV testing in the past year (a OR=2.66, 95 %CI: 1.59-4.43). Conclusion:New-type drug use is common in MSM in Shandong. The use of new-type drugs promotes unprotected sex and group sex in MSM. Surveillance and intervention measures targeting this population should be strengthened.
