A follow-up study on the pain changes trend and effects in patients diagnosed with herpes zoster in Beijing City / 中华预防医学杂志

Objective: To understand the changes in pain and its effects in patients with the diagnosis of herpes zoster. Methods: A total of 3 487 patients diagnosed with herpes zoster (HZ) for the first time at the outpatient department of Miyun District Hospital from January 1, 2017, to December 31, 2019, were included in the study. The information of patients was registered and issued with a record card. Patients were required to record the time of pain and rash by themselves. Telephone follow-up was conducted at 21, 90, 180 and 365 days after the onset of rashes, including hospitalization, location of rash and pain, and the time of start and end. The impact of pain on life was evaluated by the Zoster Brief Pain Inventory (ZBPI). Results: The age of 2 999 HZ patients included in the analysis were (53±16) years old, including 1 377 (45.91%) males and 1 903 (63.45%) patients aged 50 years and older. After 21 days of rash, mild, moderate and severe pain accounted for 20.87% (626 cases), 37.98% (1 139 cases) and 33.81% (1 014 cases), respectively. Only 5.07% (152 cases) had no pain or discomfort, and 2.27% (68 cases) had no pain but discomfort. Most of the pain sites were consistent with the rash sites. The chest and back and waist and abdomen were the most common, accounting for 35.58% (1 067 cases) and 29.18% (875 cases), respectively, followed by the limbs and face and neck, accounting for 16.74% (502 cases) and 16.40% (492 cases), respectively. The M (Q1, Q3) of pain days in the HZ patients was 14 (8, 20) days, and the incidence of post-herpetic neuralgia (PHN) was 6.63% (171/2 580) (excluding 419 patients who refused to visit or lost to visit on 90 days after the onset of rash). The pain score of HZ patients within 21 days after the rash was (5.19±2.73) points, and the pain score of PHN patients was (7.61±2.13) points, which was significantly higher than that of non-PHN patients [(5.04±2.69) points] (P<0.001). Daily activities, emotions, walking ability, work, social interaction, sleep and recreation were affected for 21 days after the rash in HZ patients, ranging from 60.79% to 83.83%, with sleep being the most affected (83.83%). The impact scores of pain and life dimensions in PHN patients ranged from 4.59 to 7.61 points on the ZBPI scale, which were higher than those in non-PHN patients (2.49-5.04) (t values ranged from 8.86 to 11.67, all P values <0.001). Conclusion: The proportion of pain in HZ patients after the diagnosis is high, and the pain is more obvious in patients with PHN and HZ patients aged 50 and older, which has a greater impact on their daily lives.

Analysis of measles immunity level in persistent populations in Beijing, 2012 / 中华预防医学杂志

<p><b>OBJECTIVE</b>To analyze the measles immunity level of persistent population in Beijing.</p><p><b>METHODS</b>A total of 2125 objects from 10 age groups, who had been living in Beijing for over 6 months, were selected from urban and rural areas in Beijing in 2012. Demographic characteristics, history of measles and vaccine immunization were investigated by questionnaire. 5 ml blood sample of each subject was collected, and the Measles IgG antibody was measured by ELISA assay.</p><p><b>RESULTS</b>Positive rate of measles antibody was 84.71% (1800/2125) and standardized positive rate was 88.07% . Median of antibody was 960.46 IU/L. Positive rate and median of measles antibody were significantly different between population from different age groups (χ(2) = 341.60, P < 0.01; H = 216.27, P < 0.01). Antibody positive rate and median were lowest in the <1 year age group, which were separately 43.06% (90/209) and 185.80 IU/L; and highest in the 1-4 (97.31% (181/186) and 2448.81 IU/L) and 5-9 years age group (96.46% (218/226) and 1910.72 IU/L). The range of antibody positive rate and median in adults of ≥ 15 years were 81.98%-90.14% and 744.38-1474.84 IU/L. Antibody positive rate and median in persistent population, which were separately 82.45% (883/1071) and 899.82 IU/L, were lower than those in migrant population, which were 87.00% (917/1054) and 166.19 IU/L, respectively (χ(2) = 8.51, P < 0.01;U = 538 704.00, P < 0.01). Antibody positive rate and median in population with vaccination history, which were separately 91.95% (891/969) and 1443.11 IU/L, were higher than those population without vaccination history and people whose history unknown (32.95% (57/173) , 127.33 IU/L; 86.67% (852/983) , 923.73 IU/L). The difference showed statistical significance (χ(2) = 399.92, P < 0.01; H = 202.11, P < 0.01).</p><p><b>CONCLUSION</b>Among the persistent population in China, measles antibody level among the children aging 1-9 years old was high enough to prevent outbreak and epidemic of measles. However, we should try our best to strengthen the measles antibody level among the babies younger than 1 year old and the migrant population aging between 15 and 40 years old.</p>

Reported willingness and associated factors related to utilization of voluntary counseling and testing services by female sex workers in Shandong Province, China / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To explore reported willingness and factors associated with utilization of voluntary counseling and testing services by female sex workers (FSWs) in China and to offer recommendations to optimize use of such services.</p><p><b>METHODS</b>A questionnaire to explore willingness to use VCT was designed based on social ecological theory and formative qualitative research. A cross-sectional survey was conducted among FSWs from entertainment venues. Single and multiple logistic regression analyses were employed to examine factors associated with reported willingness to utilize VCT.</p><p><b>RESULTS</b>A total of 970 FSWs provided valid questionnaires, with 69% (669) expressing willingness to utilize VCT. Factors at the interpersonal level associated with reported willingness included knowledge about VCT, desire to get help if diagnosed as HIV positive, ability to imagine life after an HIV positive diagnosis, and perceived support for VCT from peers, managers, and family members. Availability of free antiretroviral (ARV) treatment represented a factor at policy level. Other factors included intention to leave sex work in the near future, having had a previous HIV test, and lack of a suspected STD history.</p><p><b>CONCLUSIONS</b>The rate of reported willingness to use VCT among FSWs was substantially higher than that of actual VCT utilization (11%). The next step is to explore the connection between reported willingness and actual use. Based on these findings, peer education, VCT knowledge dissemination, and free ARV treatment should be emphasized to increase FSWs' willingness to use VCT.</p>
