Abstract
BACKGROUND Viral hepatitis imposes a heavy disease burden worldwide and is also one of the most serious public health problems in China. We aimed to describe the epidemiological characteristics of hepatitis in China and to investigate the influencing factors. METHODS We first used the JoinPoint model to analyze the percentage change (APC) and average annual percentage change (AAPC) of hepatitis in Chinese provinces from 2002 to 2021. We then explored the influencing factors by using the time-series global principal component analysis (GPCA) and the panel fixed-effects model. RESULTS The disease burden varied across different provinces from 2002 to 2021. The AAPC of the total HAV incidence decreased by 10.39% (95% CI: [-12.70%, -8.02%]) from 2002 to 2021. Yet the AAPC of HBV, HCV, and HEV increased by 1.50% (95% CI: [0.23%, 2.79%]), 13.99% (95% CI: [11.28%, 16.77%]), and 7.10% (95% CI: [0.90%, 13.69%]), respectively. The hotspots of HAV, HBV, HCV, and HEV moved from the west to the center, from the northwest to the southeast, from the northeast to the whole country, and from the northeast to the southeast, respectively. Different types of viral hepatitis infections were associated with hygiene, pollutant, and meteorological factors. Their roles in spatial-temporal incidence were expressed by panel regression functions. CONCLUSIONS Viral hepatitis infection in China showed spatiotemporal heterogeneity. Interventions should be tailored to its epidemiological characteristics and determinants of viral hepatitis.

[PMID: 38974348 PMCID: PMC11225665 DOI: 10.1016/j.imj.2024.100110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Revised: 12/17/2023] [Accepted: 04/02/2024] [Indexed: 07/09/2024]
Abstract
Background Fujian Province has one of the highest reported incidences of hepatitis B virus infection in China. This study aimed to provide a theoretical framework for preventing and controlling hepatitis B in Fujian Province, and to assess the trends and the spatial-temporal distribution patterns of hepatitis B in this region. Methods Data on hepatitis B cases were extracted from the National Notifiable Infectious Disease Surveillance System. Spatial autocorrelation analysis, trend surface analysis, and spatial-temporal scanning statistics were used to identify the spatial and aggregation patterns at the county level. The Joinpoint was used to assess the reported incidence trends. Results The average reported incidence of hepatitis B in Fujian from 2012 to 2021 was 14.46/10,000 population, with 583,262 notified cases. The age-adjusted reported incidence of hepatitis B decreased from 17.44/10,000 population in 2012 to 11.88/10,000 population in 2021, with an average reduction in the annual percentage change of 4.5%. There were obvious spatial-temporal aggregation characteristics in hepatitis B cases, and a high-incidence area was located in eastern Fujian. Spatio-temporal scanning statistics revealed four levels of aggregation of hepatitis B reporting rates. The first level of aggregation area included Minhou, Gulou, Jin'an, Taijiang, and nine other districts and counties. Conclusion The incidence of hepatitis B is declining in Fujian Province. Spatial clusters of hepatitis B cases in Fujian Province were identified, and high-risk areas in eastern Fujian still exist. Closely monitoring the general patterns in the occurrence of hepatitis B and implementing focused control and preventative strategies are important.

Neisseria gonorrhea in Ethiopia, prevalence among STI suspected patients and its antimicrobial susceptibility: a systematic review and meta-analysis. Front Microbiol 2024; 15:1390001. [PMID: 38694795 PMCID: PMC11062254 DOI: 10.3389/fmicb.2024.1390001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Accepted: 04/04/2024] [Indexed: 05/04/2024] Open
Abstract
Introduction Neisseria gonorrhea (N. gonorrhea) represents a significant causative agent of sexually transmitted infections (STIs), posing considerable global health challenges. Despite the presence of diagnostic tools and empirically guided therapies, the escalating AMR of N. gonorrhea continues to pose a threat. This study aims to assess the prevalence of N. gonorrhea among STI suspected patients in Ethiopia and explore the patterns of AMR to common antimicrobials. Methods Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a systematic review and meta-analysis. A thorough search of electronic databases from July 11 to July 24, 2023, identified 10 eligible studies. Data were extracted and analyzed using a random-effects model. Heterogeneity was assessed using the I2 statistic, and publication bias was evaluated through Egger's regression test and funnel plots. Results The overall pooled prevalence of N. gonorrhea among STI suspected patients in Ethiopia was 20% (95% confidence interval (CI): 8-30, I2 = 99.0%; p-value <0.001). Substantial regional variations were observed, with the highest prevalence in Addis Ababa (55, 95% CI: 45-65) and the lowest in the Southern Nations, Nationalities, and Peoples' Region (SNNPR) (4, 95% CI: 2-8). The pooled prevalence of AMR to ciprofloxacin, ceftriaxone, azithromycin, benzylpenicillin, tetracycline, and spectinomycin was 37, 9, 10, 79, 93, and 2%, respectively. Significant heterogeneity existed between studies (I2 = 99.0%; p value <0.001). Publication bias, identified through funnel plot examination and Egger's regression test (p < 0.001), execution of trim and fill analysis resulted in an adjusted pooled prevalence of (6.2, 95% CI: -6.8 to 19.3). Conclusion The prevalence of N. gonorrhea among STI suspected patients in Ethiopia is alarming, particularly in specific regions. The elevated AMR to ciprofloxacin underscores the immediate need for alternative treatment options and enhanced surveillance systems. Future initiatives should prioritize strengthening laboratory capacities and implementing targeted interventions to curtail N. gonorrhea transmission and prevent the emergence of AMR.

Abstract
OBJECTIVES China has the largest number of hepatitis C virus (HCV) infection in the world, but current levels of diagnosis and treatment are low. The objective of this study was to assess the cost-effectiveness of various universal HCV screening and treatment strategies in China and inform decisions on health policy. STUDY DESIGN A cost-effectiveness analytical study. METHODS We developed a Markov model to investigate cost-effectiveness of different HCV screening and treatment strategies in China. We simulated several screening scenarios for Chinese people aged 18-70 years. We estimated incremental cost-effectiveness ratios (ICERs) of different intervention scenarios compared with status quo. RESULTS Expanded HCV screening and treatment strategy with prioritisation for high-risk groups (Scenario S5) was the most cost-effective strategy (ICER: USD $11,667.71/quality-adjusted life-year [QALY] gained), which resulted in great reduction in HCV-related diseases and deaths, with a 67.11% reduction in cases of chronic HCV. Universal HCV screening and treatment implementation remains a cost-effective strategy when delayed until 2025 (ICER: USD $17,093.69/QALY), yet the delayed strategy is less effective in reducing HCV-related deaths. CONCLUSIONS Expanded HCV screening and treatment strategy with prioritisation for high-risk groups is the most cost-effective strategy and has lead to a significant reduction in both HCV morbidity and mortality in China, which would essentially eliminate HCV as a public threat.

J Public Health (Oxf) 2024; 46:72-82. [PMID: 38031291 DOI: 10.1093/pubmed/fdad222] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 09/27/2023] [Accepted: 09/29/2023] [Indexed: 12/01/2023] Open
Abstract
BACKGROUND Female sex workers (FSW) are particularly vulnerable to chlamydia and gonorrhea infections. However, there were few studies that detail the evolving patterns of chlamydia and gonorrhea among Chinese FSW. Therefore, our study endeavors to assess the prevalence of chlamydia and gonorrhea epidemics within FSW, investigate their changing trends and scrutinize associated factors. METHODS In 2019, China instituted a sentinel surveillance network focused on FSW in Guangdong Province. This network conducted an annual serial cross-sectional survey spanning from April to August. All analyses are predicated on surveillance data accumulated between 2019 and 2022. RESULTS The prevalence of chlamydia increased from 10.1 to 12.3%, exhibiting an annual percentage shift of 6.8%. Conversely, the prevalence of gonorrhea dwindled from 2.0 to 1.3%, marking an annual percentage decline of 13.4% (P < 0.001). After adjusting for covariates, chlamydia exhibited associations with having household registration in other provinces (adjusted odds ratio (aOR = 0.55)), displaying symptoms of sexually transmitted infections (STIs) (aOR = 1.65) and infected with gonorrhea (aOR = 5.68). In parallel, gonorrhea demonstrated associations with providing oral sex to clients (aOR = 3.74), manifesting STIs symptoms (aOR = 4.27) and those infected with chlamydia (aOR = 5.43). CONCLUSIONS Our observations underscore the imperative to implement a comprehensive intervention strategy concentrating on chlamydia, while simultaneously fortifying endeavors to expand the scope of gonorrhea prevention services.

Social and structural determinants associated with the prevalence of sexually transmitted infections among female commercial sex workers in Dhaka City, Bangladesh. PLOS GLOBAL PUBLIC HEALTH 2024; 4:e0002797. [PMID: 38236834 PMCID: PMC10796017 DOI: 10.1371/journal.pgph.0002797] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Accepted: 12/16/2023] [Indexed: 01/22/2024]
Abstract
Female commercial sex workers (FCSWs) bear higher rates of sexually transmitted infections (STIs) among key populations. The association of structural determinants and STIs among FCSWs was not at the forefront of research earlier in Bangladesh. This study examined how structural factors correlate with the prevalence of STIs at physical/social/economic/policy levels among FCSWs in Dhaka city. 495 FCSWs were screened for HIV, hepatitis B, and syphilis. Structural variables (Individual risks, high-risk sexual behaviors, work environments) were extracted from the previous multi-level study on FCSWs and analyzed in 2020 to determine whether macro/micro-structural factors were associated with STIs. The prevalence of STIs was 43.6% (95% CI: 39.1%-48). Most (n = 207/495) FCSWs were infected with Syphilis or Hepatitis B, only 1.8% had co-infection, and none was positive for HIV. Multiple logistic regression revealed that 'Individual risk' factors like age (≤18 years, adjusted odds ratio = AOR = .28; 18.1-29.9 years, AOR = .57), years in the sex industry (<1 year AOR = .15; 1-5 years, AOR = .39), and condoms as contraceptives (AOR = 2.7) were significantly associated with STIs. Considering 'High-risk behaviors' like monthly coitus with regular clients (AOR = .33), performing no anal sex ever (AOR = .03), and consistent condom use (AOR = .13) were less likely to be associated with STIs (P<0.05), while the association of ever group sex with STIs reported to double (AOR = 2.1). 'Work environment' like sex on roads/parks/shrines/markets (AOR = 2.6) and ever HIV-testing (AOR = 2.5) were significantly linked with STIs. However, micro-level factors like experiencing forced sex in the past year (AOR = 1.79) and condoms collected from hotel boys (AOR = .34) were significantly associated with STIs in the 'Hierarchical- model' with increasing model-power. 'Micro-structural' determinants predominated over 'Macro/policy-level factors' and profoundly influenced STIs. FCSWs need comprehensive and integrated interventions to promote accurate condom use perception, eliminate risky sexual behaviors, and provide quality reproductive health care. Necessary steps at the policy level are urgently needed to decriminalize commercial sex work.

Abstract
Syphilis is a sexually and vertically transmitted bacterial infection caused by the bacterium Treponema pallidum. Its prevalence is high in low-income and middle-income countries, and its incidence has increased in high-income countries in the last few decades among men who have sex with men. Syphilis is a major cause of adverse pregnancy outcomes in low-income and middle-income countries. Clinical features include a primary chancre at the point of inoculation, followed weeks later by the rash of secondary syphilis, a latent period, and in some cases, involvement of the eyes, CNS, and cardiovascular systems. It is diagnosed serologically. A single intramuscular dose of long-acting benzathine penicillin is recommended for people who have had syphilis for less than 1 year and longer courses for people with late latent syphilis. Control strategies include screening and treatment of all pregnant women, and targeted interventions for groups at high risk. Vaccine development, research on antibiotic prophylaxis, and digital messaging as prevention strategies are ongoing.

Abstract
OBJECTIVES This systematic review was conducted to estimate the respective prevalence of gonorrhea among two high-risk populations in China and determine the epidemiological features of gonorrhea in them. STUDY DESIGN Systematic review. METHODS PubMed, Web of Science, China National Knowledge Infrastructure, and Wanfang databases were searched to identify studies published between January 1, 1990, and October 31, 2022, with gonorrhea prevalence tested by polymerase chain reaction among female sex workers (FSWs) and men who have sex with men (MSM). Meta-regression and subgroup analyses were used to investigate potential factors of heterogeneity across studies. Trend analysis of prevalence was conducted by the Jonckheere-Terpstra method. RESULTS We identified 88 prevalence data points from 49 studies in China, with 30,853 participants of FSWs and 5523 participants of MSM. Pooled prevalence of gonorrhea among FSWs and MSM were 6.9% (95% confidence interval: 4.6-9.7%) and 2.5% (95% confidence interval: 1.5-3.7%), respectively. The subgroup analyses showed there were period, regional, and specimen collection methods diversities among FSWs, and diversities of the regions and specimen collection anatomical sites were found among MSM, in which the prevalence of rectum and pharynx was significantly higher than the urethra. A decreasing trend in the prevalence of gonorrhea was seen among FSWs (z = -4.03) from 1999 to 2021, not found for MSM in China. CONCLUSION The prevalence of gonorrhea is high in two high-risk groups in China, with extragenital infections requiring particular attention. The findings of this study will provide evidence to formulate national policy and guidance for gonorrhea prevention and control.

Abstract
INTRODUCTION Neisseria gonorrhoeae causes gonorrhoea, a globally neglected but increasing disease. This systematic review and meta-analysis reviewed the epidemiology and economic burden of gonorrhoea in Latin America and the Caribbean (LAC). METHODS We searched PubMed, EMBase, Cochrane Library, EconLIT, CINAHL, CRD, LILACS, Global Health, Global Dissertations and Theses, SciELO, Web of Science databases, countries' ministries of health, and the IHME's Global Burden of Disease databases. Studies published in the last 10 years (20 years for economic studies) were included if conducted in any LAC country, without language restrictions. The main outcome measures were incidence/prevalence, proportion of co-infections, case fatality rates, specific mortality/hospitalisation rates, direct/indirect costs, and impact of gonorrhoea on quality of life. To assess evidence quality, we used a checklist developed by the US National Heart, Lung, and Blood Institute for observational studies and trial control arms, the Cochrane Effective Practice Organization of Care Group tool for randomised controlled trials, and the CICERO checklist for economic studies. RESULTS We identified 1290 articles; 115 included epidemiological studies and one included an economic study. Ministry of health data from Argentina, Brazil, Chile, Colombia, Mexico, and Uruguay were identified. Gonorrhoea prevalence was 1.46% (95% confidence interval [CI] 1.00-2.00%) from 48 studies and 5.68% (95% CI 4.23-7.32%) from 58 studies for non-high-risk and high-risk populations, respectively. Cumulative incidence for the high-risk population was 2.05 cases per 100 persons/year. Few published studies were rated as "good" in the risk of bias assessments. Variations in the methodology of the sources and limited information found in the countries' surveillance systems hinder the comparison of data. CONCLUSION The burden of gonorrhoea in LAC is not negligible. Our results provide public health and clinical decision support to assess potential interventions to prevent gonorrhoea. TRIAL REGISTRATION The protocol is registered on PROSPERO (CRD42021253342). The study was funded by GlaxoSmithKline Biologicals SA (GSK study identifier VEO-000025).

Abstract
BACKGROUND AND AIMS A high prevalence of hepatitis delta virus (HDV) infection, the most severe form of viral hepatitis, has been reported among persons living with HIV (PLWH) in Europe. We analysed data from a large HIV cohort collaboration to characterize HDV epidemiological trends across Europe, as well as its impact on clinical outcomes. METHODS All PLWH with a positive hepatitis B surface antigen (HBsAg) in the Swiss HIV Cohort Study and EuroSIDA between 1988 and 2019 were tested for anti-HDV antibodies and, if positive, for HDV RNA. Demographic and clinical characteristics at initiation of antiretroviral therapy were compared between HDV-positive and HDV-negative individuals using descriptive statistics. The associations between HDV infection and overall mortality, liver-related mortality as well as hepatocellular carcinoma (HCC) were assessed using cumulative incidence plots and cause-specific multivariable Cox regression. RESULTS Of 2793 HBsAg-positive participants, 1556 (56%) had stored serum available and were included. The prevalence of HDV coinfection was 15.2% (237/1556, 95% confidence interval [CI]: 13.5%-17.1%) and 66% (132/200) of HDV-positive individuals had active HDV replication. Among persons who inject drugs (PWID), the prevalence of HDV coinfection was 50.5% (182/360, 95% CI: 45.3%-55.7%), with similar estimates across Europe, compared to 4.7% (52/1109, 95% CI: 3.5%-5.9%) among other participants. During a median follow-up of 10.8 years (interquartile range 5.6-17.8), 82 (34.6%) HDV-positive and 265 (20.1%) HDV-negative individuals died. 41.5% (34/82) of deaths were liver-related in HDV-positive individuals compared to 17.7% (47/265) in HDV-negative individuals. HDV infection was associated with overall mortality (adjusted hazard ratio 1.6; 95% CI 1.2-2.1), liver-related death (2.9, 1.6-5.0) and HCC (6.3, 2.5-16.0). CONCLUSION We found a very high prevalence of hepatitis delta among PWID across Europe. Among PLWH who do not inject drugs, the prevalence was similar to that reported from populations without HIV. HDV coinfection was associated with liver-related mortality and HCC incidence.

Abstract
A dose-escalation, randomized, double-blind, placebo-controlled phase 1 clinical trial enrolled 145 eligible participants aged 18-55 years in March 2015 in Liuzhou, China. Stratified by age and sex, the participants were randomly assigned to receive either 30, 60, or 90 μg of the HPV-6/11 vaccine (n = 41/40/40) or the parallel placebo vaccine (n = 8/8/8) with a 0/1/6-month dose-escalation schedule. Participants were actively followed-up to record local and systemic AEs occurring within 30 days after each vaccination, and SAEs occurred in 7 months. Blood and urine samples of each participant were collected before and 2 days after the first and third vaccination to determine changes in routine blood, serum biochemical, and urine indexes. Serum HPV-6/11-specific IgG and neutralizing antibody levels at month 7 were analyzed. A total of 79 adverse events were reported, and no SAEs occurred. The incidences of total adverse reactions in the 30 μg, 60 μg, and 90 μg HPV vaccine groups and the control group were 31.7%, 50.0%, 42.5%, and 62.5%, respectively. All but one of the adverse reactions was mild or moderate with grade 1 or 2. No vaccine-related changes with clinical significance were found in paired blood and urine indexes before and after vaccinations. All the participants in the per-protocol set seroconverted at month 7 for both IgG and neutralizing antibodies. The candidate novel Escherichia-coli-produced bivalent HPV-6/11 vaccine has been preliminarily proven to be well tolerated and with robust immunogenicity in a phase 1 clinical study, supporting further trials with larger sample size. The study has been registered at ClinicalTrials.gov (NCT02405520).

HPV types 16/18 L1 E6 and E7 proteins seropositivity and cervical cancer risk in HIV-positive and HIV-negative black South African women. Infect Agent Cancer 2022; 17:14. [PMID: 35351184 PMCID: PMC8966297 DOI: 10.1186/s13027-022-00418-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Accepted: 02/11/2022] [Indexed: 11/24/2022] Open
Abstract
Background In populations with high rates of human immunodeficiency virus (HIV)-coinfection, the nature of the relationship between human papillomavirus (HPV)-16 and -18 (L1, E6 and E7) antibodies and cervical cancer is still uncertain. We measured the association between seropositivity to HPV (L1, E6 and E7) proteins and cervical cancer among black South African women with and without HIV co-infection. Methods We used questionnaire data and serum collected from consecutively recruited patients with a newly diagnosed cancer from the Johannesburg Cancer Study from 1346 cervical cancer cases and 2532 controls (diagnosed with other non-infection related cancers). Seropositivity to HPV proteins was measured using a multiplex serological assay based on recombinant glutathione S-transferase (GST) fusion proteins. We measured associations between their presence and cervical cancer using unconditional logistic regression models and evaluated the sensitivity and specificity of these HPV biomarkers. Results Among controls, HIV-negative women from rural areas compared to urban had significantly higher HPV seroprevalence, HPV16 E7 (8.6% vs 3.7%) and HPV18 E7 (7.9% vs 2.0%). HPV16 E6 and E7 antibodies were positively associated with cervical cancer in HIV-positive (Adjusted Odds Ratio (AOR) = 33; 95% CI 10–107) and HIV-negative women (AOR = 97; 95% CI 46–203). In HIV-positive women, HPV E6/E7 antibodies had low sensitivity (43.0%) and high specificity (90.6%) for cervical cancer detection. In HIV-negative women, HPV E6/E7 antibodies sensitivity was 70.6% and specificity was 89.7%. Conclusions Our data show that HPV (L1, especially E6 and E7) antibody positivity is associated with cervical cancer in both HIV-positive and HIV-negative women. Nonetheless, being HIV-positive plays an important role in the development of cervical cancer.

Abstract
Background Female sex workers (FSWs) are a marginalized group notoriously having limited healthcare access and poor-quality care. Inevitably, they are vulnerable to sexually transmitted infections including hepatitis B virus. However; Hepatitis B virus infection is one of the most serious infections and major public health problem considered to be at soaring risk for transmission and acquisition of the infection. Hence, this study was aimed to assess the prevalence and associated factors of HBV infections among FSWs in southern Ethiopia. Methods A cross-sectional study was conducted from November to February 2019 at Hawassa city in ISHDO confidential clinic among 383 FSWs. Respondent-driven consecutive sampling was used to select study participants using a standardized questionnaire. Blood sample was collected and viral surface antigen was detected using ELISA from separated serum. Data were entered to SPSS version 21.0. Descriptive and logistic regression analyses were used. Result The overall prevalence of FSWs who were tested for HBV using ELISA was 35(9.2%) (95% CI: 6.3–12.1). Among 381 FSWs 249(65.4%) were stayed for 2–5 years in sexual work and 240(63%) of them were used condom consistently during sexual practice. In multivariate logistic regression analysis, FSWs who didn’t use condom were six and two times more risk full to acquire HBV than those who used condom commonly (AOR = 6.38, CI 2.04–18.51) and condom breakage (AOR = 2.10, CI 1.95–4.65), during sexual practice respectively. Similarly, use of stimulants (AOR = 3.25, CI 1.59–18.63), previous history of STI (AOR = 2.15, CI 1.02–6.93), genital ulcer (AOR = 4.64, CI 1.31–11.35), number of sexual partners (AOR = 3.25, CI 1.59–7.47), sex during menses (AOR = 5.85, CI (1.29–21.44), sexual assault (AOR = 2.93, CI 1.23–9.01), sharp material sharing, (AOR = 4.98, CI 1.34–10.95) and history of abortion, (AOR = 2.46, CI 1.18, 12.19), were statistically associated with HBV infection. Factors such as age, residence, and alcohol consumption were not associated with HBV infection. Conclusion The prevalence of HBV infection in this study was relatively high compared to the general population. Factors like sociodemographic, behavioral, and previous history-related information were associated with HBV infection shows the need for ongoing screening of high-risk population to inform planning for vaccination and preventive measures.

Prevalence and associated factors of sexually transmitted infections among methamphetamine users in Eastern China: a cross-sectional study. BMC Infect Dis 2022; 22:7. [PMID: 34983422 PMCID: PMC8725376 DOI: 10.1186/s12879-021-06987-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Accepted: 12/14/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The reported incidence of sexually transmitted infections (STIs) in China has been increasing over the last decades, especially among drug users, which has become one of the main burdens of public health in China. This study was conducted to estimate the prevalence and associated factors of STIs among non-injecting methamphetamine (MA) users in Eastern China. METHODS A cross-sectional survey was conducted among 632 MA users in Eastern China in 2017. Demographic characteristics, sexual behaviors, behaviors of MA use and sexual health knowledge were collected through questionnaire. First pass urine specimens were collected and detected for deoxyribonucleic acid (DNA) of Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) with Nucleic Acid Amplification Technology (NAAT), while blood specimens were collected and detected for antibodies of Human immunodeficiency virus (HIV), Herpes simplex virus type-2 (HSV-2), and syphilis with enzyme-linked immune sorbent assay (ELISA). RESULTS Among the 632 MA users, 464 (73.42%) were males, 60.92% were < 35 years of age, 546 (86.39%) were Shandong residents. 317 (50.16%, 95% CI 46.26-54.06%) participants were tested positive for at least one kind of STIs, including 242 (38.29%, 95% CI 34.50-42.08%) for HSV-2, 107 (16.93%, 95% CI 14.01-19.85%) for active syphilis, 46 (7.28%, 95% CI 5.25-9.31%) for treated syphilis, 40 (6.33%, 95% CI 4.43-8.23%) for CT, 6 (0.95%, 95% CI 0.19-1.71%) for HIV, and 3 (0.47%, 95% CI 0.06-1.00%) for NG infection. 99 (15.66%, 95% CI 12.83-18.49%) participants were co-infected with two kinds of STIs, including 91 (14.40%, 95% CI 11.66-17.14%) participants were co-infected with HSV-2 and syphilis. 14 (2.22%, 95% CI 1.07-3.37%) participants were co-infected with three kinds of STIs, and 4 HIV positive participants were co-infected with both syphilis and HSV-2. In the multiple logistic regression analysis, the results showed that females (adjusted OR [AOR] = 7.30, 95% CI 4.34-12.30) and individuals ≥ 35 years of age (AOR = 2.97, 95% CI 2.04-4.32) were more likely to test positive for STIs among MA users, whereas participants who acquired sexual health knowledge primarily from the Internet (AOR = 0.57, 95% CI 0.40-0.82) and those whose regular partners did not use drugs (AOR = 0.59, 95% CI 0.37-0.94) were less likely. CONCLUSIONS This study found that the prevalence of HSV-2 and syphilis are alarming high among non-injecting MA users in Shandong Province in Eastern China. The prevention and control intervention of STIs among MA users in Shandong were needed, especially on females and MA users ≥ 35 years of age.

[PMID: 34688632 DOI: 10.1016/j.actatropica.2021.106204] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 10/08/2021] [Accepted: 10/16/2021] [Indexed: 11/19/2022]
Abstract
BACKGROUND Two cervical cancer screening (CCS) projects have been ongoing for years in Guangxi Zhuang autonomous region (Guangxi), and some Trichomonas vaginalis infection (TVI) cases have been found as an opportunistic finding. This study aimed to identify the high-risk population and expound the spatial epidemiological features of TVI in Guangxi. METHODS This study was based on CCS from 2012 to 2019. Adjusted odds ratio (AOR), and spatial analyses were used to identify the high-risk subgroups, as well as to depict the spatial epidemiological feature and its relationship with meteorological factors. RESULTS The infection rate of TVI was 0.38% in 873,880 samples. Significant association with a high risk of TVI was found in the following: females aged 40-49 years (aOR=4.464; 95% CI, 3.359-5.932; p<0.001), aged 50-59 years (aOR=3.169; 95% CI, 2.370-4.237; p<0.001), from urban (aOR=1.577; 95% CI, 1.471-1.691; p<0.001), from minority areas (aOR=1.183; 95% CI, 1.060-1.320; p=0.003), areas with GPD <41,500 CNY (aOR=1.191; 95% CI, 1.106-1.282; p<0.001), and inland areas (aOR=1.520; 95% CI, 1.339-1.726; p<0.001). Counties with higher infection rate were concentrated in northwest Guangxi's mountainous area (Z-score=3.9656, p<0.001), in the upper reaches of the Hongshui River and Yu River, and with a significant spatial autocorrelation (Moran's I=0.581, p=0.002). Spatial error model showed significantly negative regressions among temperature (B=-0.295, p=0.002), annual temperature range (B=-0.295, p=0.002), and TVI spatial distribution. CONCLUSION The spatial clustering and disparity of TVI in northwest Guangxi warrant further study, and meteorological conditions may play an important role in TVI in northwest Guangxi.

[PMID: 34707375 PMCID: PMC8542596 DOI: 10.2147/idr.s332333] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Accepted: 10/05/2021] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Female sex workers (FSWs) are a marginalized group having limited healthcare access and poor-quality care. Inevitably, they are vulnerable to sexually transmitted infections including hepatitis B virus. It is one of the most serious and major public health problems, with an increased risk of transmission and acquisition of the infection. Hence, this study was aimed to assess the prevalence and associated factors of HBV infection among FSWs in southern Ethiopia. METHODS A cross-sectional study was conducted from November to February 2019 at Hawassa city among ISHDO confidential clinics among 383 FSWs using respondent-driven consecutive sampling techniques to select study participants using a standardized questionnaire. The blood samples were collected to detect viral surface antigen using ELISA. Data were entered into SPSS version 21. Descriptive and logistic regression analysis was used. RESULTS The overall prevalence of HBV was 35 (9.2%) (95% CI=6.3-12.1). Among 381 FSWs, 249 (65.4%) of them had stayed for 2-5 years in sexual work. A total of 240 (63%) of them used condoms consistently during sexual practice. In multivariate analysis, FSWs who did not use a condom during sexual practice were 6-times more at risk than those who used a condom (AOR=6.38, CI=2.04-18.51). Condom breakage (AOR=2.10, CI=1.95-4.65), use of stimulants (AOR=3.25, CI=1.59-18.63), history of STI (AOR=2.15, CI=1.02-6.93), and genital ulcer (AOR=4.64, CI=1.31-11.35), number of sexual partners (AOR=3.25, CI=1.59-7.47), sex during menses (AOR=5.85, CI=1.29-21.44), sexual assault (AOR=2.93, CI=1.23-9.01), sharp material sharing (AOR=4.98, CI=1.34-10.95), and history of abortion (AOR=2.46, CI=1.18-12.19) were statistically associated with HBV infection. CONCLUSION The prevalence of HBV infection in this study was relatively high compared to the general population. Factors like sociodemographic, behavioral, and previous information were associated with HBV infection. There is a need for ongoing screening of this high-risk population to inform planning for vaccination and preventive measures.

Abstract
Sex workers, including female ones, have a higher risk of developing cancer and oral diseases due to the overlapping of risk factors. To characterize oral health status and healthcare practices and behaviors in female sex workers. Both quantitative and qualitative concomitant approaches were used. A closed-ended questionnaire, clinical examination, and semi-structured interview were administered, from July 2017 to August 2018, to 21 intentionally selected participants, in the city of Itajaí, southern Brazil. Although the participants reported having good oral health and healthcare habits, some oral diseases and harmful habits were observed. Poor oral hygiene and habits such as smoking, alcohol, and illicit drug use were found. Most of the participants had undergone gynecological follow-up in the last 12 months. Qualitative analysis gave rise to six categories: Social aspects of working as a sex worker, Work routine, Sexual practices and behaviors and protection from sexually transmitted infections, Practices and behaviors (including unprotected sun exposure, smoking, and alcohol use at work), Use of illicit drugs at work, and General and oral health care and perceptions about their oral health. Oral health status of the participants was variable, and most of them smoked cigarettes, drank alcohol, and consumed illicit drugs at work. Preventive condom use was reported. Most of them underwent recent serological tests for sexual diseases and gynecological follow-up, incentivized by the community health workers that facilitate access to public services.

Abstract
BACKGROUND Female sex workers (FSW) are highly susceptible to chlamydia and gonorrhea infection. However, there is limited literature examining their testing uptake to date. This study aimed to assess the uptake and determinants of chlamydia and gonorrhea testing among FSW in Southern China. METHODS A cross-sectional study with convenience sampling was performed in five cities in Southern China. Data on socio-demographic characteristics, sexual behaviors, chlamydia and gonorrhea testing, and the utilization of health care services from participants were collected through face-to-face interviews. Univariate and multivariable logistic regressions were used to determine factors associated with chlamydia and gonorrhea testing, respectively. RESULTS Overall, 1207 FSWs were recruited, with the mean age of 30.7 ± 6.8 years and an average number of clients of 7.0 (4.0-10.0) per week. 65.4% participants constantly used condoms with clients during the past month. Only 7.5 and 10.4% had been tested for chlamydia and gonorrhea in the last year, respectively. Multivariable analysis indicated that FSW who worked at low tiers (adjusted Odds Ratio (aOR) = 2.36, 95%CI:1.23-10.14), had more clients in the last month (aOR = 1.03, 95%CI:1.01-1.05), used condoms consistently (aOR = 1.79, 95%CI:1.12-2.86), had STD symptoms (aOR = 4.09,95%CI:2.62-6.40), had been tested for HIV (aOR = 5.16, 95%CI:3.21-8.30) or syphilis (aOR = 6.90, 95%CI:4.21-11.22) in the last year were more likely to have chlamydia testing. In addition, FSW who had more clients in the past month (aOR = 1.02,95%CI:1.00-1.04), had STD symptoms (aOR = 3.33, 95%CI:2.03-5.46), had been tested for HIV (aOR = 3.94, 95%CI:2.34-6.65) and syphilis (aOR = 3.27, 95%CI:1.96-5.46) in the last year were more likely to have gonorrhea testing. CONCLUSIONS The testing rates of chlamydia and gonorrhea are low among Chinese FSW. Integrating chlamydia and gonorrhea testing into HIV testing promotion programs may help bridge the gap among FSW.

Abstract
Background There are limited published data on factors related to risky sexual practices (RSP) affecting sexually transmitted infections (STIs) among female sex workers (FSWs) in Ecuador. Methods Cross-sectional study of FSWs presenting for a consultation in a primary health care centre during 2017. A questionnaire was administered to collect information on RSP and potential risk factors including age, membership of an FSW association, self-report of previous STI diagnosis, previous treatment for suspected STI and temporary migration for sex work. Associations between RSP and potential risk factors were estimated by logistic regression. The proportion of STI was estimated from vaginal swabs by real-time PCR for four sexually transmitted pathogens (Neisseria gonorrhoeae, Trichomonas vaginalis, Chlamydia trachomatis, and Mycoplasma genitalium). Results Of 249 FSWs recruited, 22.5% had reported RSPs at least once during sex work. Among FSWs reporting unprotected vaginal sex in the previous three months, 25.5% had at least one other RSP type. 17.6% (95%CI 13.3–22.8) had at least one active STI. Prevalence of co-infections was 2.4% (95%CI 1.1–5.2). In multivariable analysis, RSP was associated with age (adjusted OR 1.06; 95%CI 1.02–1.10), membership of an FSWs association (aOR 3.51; 95%CI 1.60–7.72) and self-reported previous STI (aOR 3.43; 95%CI 1.28–9.17). Conclusions Among a population of female sex workers with high proportion of STIs, increasing age and belonging to an FSWs association was associated with a higher likelihood of engaging in RSP with clients. Engaging with FSWs organisations may reduce the burden of STI among sex workers.

Abstract
Syphilis control programs have been scaled up due to the substantial burden in China. We analyzed syphilis incidence according to demographic, spatiotemporal, and economic factors. The increasing latent syphilis diagnoses and declining congenital syphilis suggest the effectiveness of scale-up screening. However, primary and secondary cases persist, especially in inland provinces.

Abstract
OBJECTIVES To explore the prevalence and changing trends of HIV, syphilis, hepatitis C virus (HCV) infections and risk behaviours among female sex workers (FSWs) and to provide reference and theoretical basis for formulating targeted interventions. DESIGN Six consecutive cross-sectional surveys. SETTING Chongqing, China. PARTICIPANTS FSWs were included if they (1) were aged ≥16 years, (2) provided commercial sex for money or goods during the previous month and (3) were willing to participate in the survey and could provide verbal informed consent. This study included 16 791 of 16 810 participants recruited between 2013 and 2018. PRIMARY AND SECONDARY OUTCOME MEASURES The prevalence of HIV/syphilis/HCV infection. RESULTS The HIV and HCV prevalence among FSWs in Chongqing was stable during the study period, but the prevalence of syphilis had an increasing trend, particularly among low-tier and middle-tier FSWs. Improvements in HIV-related knowledge, condom use, injecting drug use and participation in HIV-related services were observed. However, no change was found in the prevalence of drug use. HIV infection was correlated with no condom use in the last commercial sex (adjusted OR (aOR) 3.48, 95% CI 1.90 to 6.37) and syphilis infection (aOR 4.88, 95% CI 1.95 to 12.18). Syphilis infection was correlated with inconsistent condom use (aOR 1.30, 95% CI 1.02 to 1.65), HIV infection (aOR 5.88, 95% CI 2.40 to 14.41), HCV infection (aOR 7.68, 95% CI 4.37 to 13.49) and sexually transmitted infection (STI) diagnosis in the past year (aOR 3.81, 95% CI 2.40 to 6.03). HCV infection was associated with injecting drug use (aOR 8.91, 95% CI 4.45 to 17.86) and syphilis infection (aOR 7.88, 95% CI 4.49 to 13.83). CONCLUSIONS Comprehensive interventions targeting FSWs, particularly low-tier and middle-tier FSWs, should be increasingly implemented to prevent and control HIV, syphilis and other STIs.

Abstract
This paper evaluates correlates of trichomoniasis among female sex workers who inject drugs (FSWIDs) in two Mexico-US border cities. HIV-negative FSWIDs aged 18 years or older were enrolled in a study between 2008 and 2010 in Tijuana and Ciudad Juarez (Cd.), Mexico. All participants underwent a baseline interviewer-administered survey and did a rapid test for trichomoniasis. Using regression to estimate prevalence ratios, we examined sociodemographics, sex work characteristics, sexual health and behavior, substance use, and police and violence exposures as potential correlates of trichomoniasis. Of 584 women (284 in Tijuana, 300 in Cd. Juarez), prevalence of trichomoniasis was 33.6%. Factors associated with trichomoniasis in multivariable analysis were having money stolen by police in the past six months (adjusted prevalence ratio [aPR] =1.448, 95% confidence interval [CI] = 1.152-1.821), recent methamphetamine use (aPR = 1.432, CI = 1.055-1.944), lifetime syphilis infection (aPR = 1.360, CI = 1.061-1.743), ever use of a home remedy to treat vaginal symptoms (aPR = 1.301, CI = 1.027-1.649), and number of regular clients in the past month (aPR = 1.006 per client, CI = 1.004-1.009), while controlling for age and city of interview. Alongside the need for trichomoniasis surveillance and treatment programs, findings indicate that both structural and behavioral factors serve as primary correlates of trichomoniasis among FSWIDs in these cities.

Sexually transmissible infections among female sex workers in Amsterdam between 2011 and 2016: does risk vary by work location? Sex Health 2020; 17:368-376. [PMID: 32731918 DOI: 10.1071/sh19153] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Accepted: 06/11/2020] [Indexed: 11/23/2022]
Abstract
Background Female sex workers (FSW) are at risk for sexually transmissible infections (STI). This study aimed to investigate whether the risk for chlamydia and gonorrhoea differs by work location among FSW in Amsterdam. Additionally, trends in STI positivity rates between 2011 and 2016 were assessed. METHODS This was a retrospective analysis of routinely collected clinical data during STI consultations of FSW by the Prostitution and Healthcare Centre (P&G292). Work location was categorised as window prostitution, escorts/homeworkers, clubs/brothels/private houses/massage salons and other. RESULTS In total, 7558 STI consultations of 2529 FSW in the period 2011-16 were included. Positivity rates for chlamydia and gonorrhoea were 6.6% and 2.0%, respectively. Infectious hepatitis B virus, syphilis and HIV were diagnosed in <0.2% of consultations. Positivity rates of chlamydia and rectal gonorrhoea differed significantly by work location (P < 0.001). Genital and rectal chlamydia and rectal gonorrhoea were significantly less likely among women working in window prostitution, except for the other-group. Risk factors for STI did not vary by work location. Among women working in window prostitution, positivity rates for oropharyngeal and genital chlamydia and genital gonorrhoea were significantly decreasing between 2011 and 2016 (P trend <0.05). CONCLUSIONS The higher STI positivity among escorts/homeworkers and FSW in clubs/brothels/private houses/massage salons emphasises the need for extra attention to improve condom use and STI testing in this group. Factors associated with STI did not vary by work location, thus interventions, including those used by P&G292, to reduce STI risk, can be used for women at all work locations.

Abstract
Background Female sex workers (FSWs) are key groups in the transmission of sexual transmitted infections (STI), and vaginal microbiome variations play an important role in transmission. We aimed to explore the characteristics of vaginal microbiome among FSWs. Materials and Methods A total of 24 cross-border FSWs were randomly selected from a cross-sectional survey for female sex workers in southwest China. Thirty-seven female non-sex workers (FNSWs) were randomly selected from the gynecology clinic and health examination center. Vaginal swabs were collected, bacterial DNA extracted and 16S rRNA genes were sequenced. Differences in the vaginal microbiome between both groups were compared using bioinformatics analysis. Results One DNA sample was excluded due to unqualified concentration, therefore 60 samples were sequenced. FSWs had significantly different vaginal microbiota β diversity, but undifferentiated α diversity when compared with non-sex workers. The average relative abundance of Sneathia, Shigella, Neisseria, Chlamydia, Prevotella, Enterococcus and Ureaplasma among FSWs was higher than FNSWs, and relative abundance of Atopobium in FSWs was lower than FNSWs. The Lactobacillus genus was the major genus in both groups. At the species level, Lactobacllus crispatus, Lactobacllus gasseri and Lactobacllus jensenii, in female sex workers, were lower when compared to FNSWs. Conclusion There were distinct differences in vaginal bacteria variety between FSWs and FNSWs. Some disease-related genus were also more abundant in FSWs. Based on these observations, further research is required to identify microbiome communities related to high STI risks and other diseases in these cohorts.

Abstract
This cross-sectional study describes the prevalence and context of violence by sexual partners against female sex workers (FSWs, N = 589) in Andhra Pradesh and its association with alcohol use by FSWs and abusive partners. In all, 84% of FSWs reported alcohol use; 65% reported lifetime physical abuse by a sexual partner. Most abused women suffered abuse from multiple partners, often triggered by inebriation or FSW's defiance. In multivariate logistic regressions, frequency of FSW's alcohol use was associated with abuse by clients and primary partner, whereas partner's alcohol use was only significant for abuse by primary partner, not clients.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:E661. [PMID: 29614809 PMCID: PMC5923703 DOI: 10.3390/ijerph15040661] [Citation(s) in RCA: 38] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/13/2018] [Revised: 03/19/2018] [Accepted: 03/30/2018] [Indexed: 12/18/2022]
Abstract
Viral hepatitis, as one of the most serious notifiable infectious diseases in China, takes heavy tolls from the infected and causes a severe economic burden to society, yet few studies have systematically explored the spatio-temporal epidemiology of viral hepatitis in China. This study aims to explore, visualize and compare the epidemiologic trends and spatial changing patterns of different types of viral hepatitis (A, B, C, E and unspecified, based on the classification of CDC) at the provincial level in China. The growth rates of incidence are used and converted to box plots to visualize the epidemiologic trends, with the linear trend being tested by chi-square linear by linear association test. Two complementary spatial cluster methods are used to explore the overall agglomeration level and identify spatial clusters: spatial autocorrelation analysis (measured by global and local Moran's I) and space-time scan analysis. Based on the spatial autocorrelation analysis, the hotspots of hepatitis A remain relatively stable and gradually shrunk, with Yunnan and Sichuan successively moving out the high-high (HH) cluster area. The HH clustering feature of hepatitis B in China gradually disappeared with time. However, the HH cluster area of hepatitis C has gradually moved towards the west, while for hepatitis E, the provincial units around the Yangtze River Delta region have been revealing HH cluster features since 2005. The space-time scan analysis also indicates the distinct spatial changing patterns of different types of viral hepatitis in China. It is easy to conclude that there is no one-size-fits-all plan for the prevention and control of viral hepatitis in all the provincial units. An effective response requires a package of coordinated actions, which should vary across localities regarding the spatial-temporal epidemic dynamics of each type of virus and the specific conditions of each provincial unit.

[PMID: 29408881 PMCID: PMC5800545 DOI: 10.1371/journal.pmed.1002499] [Citation(s) in RCA: 63] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2017] [Accepted: 01/02/2018] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Gonorrhea remains one of the most common sexually transmitted diseases worldwide. Successful treatment has been hampered by emerging resistance to each of the antibiotics recommended as first-line therapies. We retrospectively analyzed the susceptibility of gonorrhea to azithromycin and ceftriaxone using data from the China Gonococcal Resistance Surveillance Programme (China-GRSP) in order to provide evidence for updating the treatment recommendations in China. METHODS AND FINDINGS In this study, we included 3,849 isolates collected from patients with a confirmed positive Neisseria gonorrhoeae (N. gonorrhoeae) culture at clinic visits during the period of 1 January 2013 through 31 December 2016 in 7 provinces. Antimicrobial susceptibility testing of gonorrhea isolates using agar dilution was conducted to determine minimum inhibitory concentration (MIC). Resistance to azithromycin (RTA) was defined as MIC ≥ 1.0 mg/l, and decreased susceptibility to ceftriaxone (DSC) was defined as MIC ≥ 0.125 mg/l. The prevalence of isolates with RTA was 18.6% (710/3,827; 95% CI 17.4%-19.8%). The percentage of patients with DSC fluctuated between 9.7% and 12.2% over this period. The overall prevalence of isolates with both RTA and DSC was 2.3% (87/3,827; 95% CI 1.9%-2.8%) and it increased from 1.9% in 2013 to 3.3% in 2016 (chi-squared test for trend, P = 0.03). Study limitations include the retrospective study design and potential biases in the sample, which may overrepresent men with symptomatic infection, coastal residents, and people reporting as heterosexual. CONCLUSIONS To our knowledge, this is the first national study on susceptibility of N. gonorrhoeae to azithromycin and ceftriaxone in China. Our findings indicate high rates of RTA and DSC from 2013 to 2016. Although dual therapy with azithromycin and ceftriaxone has been recommended by WHO and many countries to treat gonorrhea, reevaluation of this therapy is needed prior to its introduction in China.

Abstract
To determine the incidence of anogenital warts (AGWs) in the Chinese general population, we compared the data from a prospective study and from the National Notifiable Disease Report System (NNDRS). A cohort study including 2378 women and 2309 men aged 18-55 years old enrolled from Liuzhou, China, was conducted with three scheduled visits at 6-month intervals from May 2014 to March 2016. And, a questionnaire survey was performed to collect the diagnosis history of AGWs at the enrollment visit. The data on reported AGW cases of Liuzhou in the NNDRS from 2006 to 2015 were also analyzed. Overall, the incidence rates of AGWs in the prospective study, in the self-reported diagnosis during past 12 months and in the NNDRS were 1.26 per 1000 person-years (95% confidence interval (CI): 0.16-2.37), 2.35 (95% CI: 1.17-4.20) and 0.183 (95% CI: 0.178-0.187), respectively. Human papillomavirus 6 or 11 were found in all the AGW biopsy samples (10/10). The onset time of AGWs in women was earlier, and the cumulative risk increased more quickly at a young age along with each subsequent younger birth cohort (P<0.0001), whereas slight differences were observed in the different male birth cohorts (P=0.0785). The sexual behavior of individuals and their sexual partners had a strong relationship with self-reported AGWs. Our study indicates that the incidence of AGWs in China is as high as that in developed countries, and the data based on the national surveillance system seriously underestimate the real disease burden of AGWs.

Abstract
Treponema pallidum subspecies pallidum (T. pallidum) causes syphilis via sexual exposure or via vertical transmission during pregnancy. T. pallidum is renowned for its invasiveness and immune-evasiveness; its clinical manifestations result from local inflammatory responses to replicating spirochaetes and often imitate those of other diseases. The spirochaete has a long latent period during which individuals have no signs or symptoms but can remain infectious. Despite the availability of simple diagnostic tests and the effectiveness of treatment with a single dose of long-acting penicillin, syphilis is re-emerging as a global public health problem, particularly among men who have sex with men (MSM) in high-income and middle-income countries. Syphilis also causes several hundred thousand stillbirths and neonatal deaths every year in developing nations. Although several low-income countries have achieved WHO targets for the elimination of congenital syphilis, an alarming increase in the prevalence of syphilis in HIV-infected MSM serves as a strong reminder of the tenacity of T. pallidum as a pathogen. Strong advocacy and community involvement are needed to ensure that syphilis is given a high priority on the global health agenda. More investment is needed in research on the interaction between HIV and syphilis in MSM as well as into improved diagnostics, a better test of cure, intensified public health measures and, ultimately, a vaccine.

Abstract
Background. Our study aimed to assess the burden of depression and evaluate factors associated with depression and status of HIV risk behaviors among female sex workers (FSWs) in Guangdong, China. Method. We recruited FSWs from massage parlors, saunas, restaurants, hotels, hair salons, and streets in Guangdong, China, in 2014. Information on demographic characteristics, HIV testing history, and sexual behaviors was collected using a questionnaire. A blood sample was collected to test for HIV, syphilis, and HCV. A participant was defined as being depressed if she obtained 6 points or above using the 12-item General Health Questionnaire. Results. Among the 653 participants, 41.7% were 21–30 years old and 43.6% married. Overall, 52.4% were found to be depressed. FSWs who had correct syphilis related knowledge [aOR = 1.45; 95% CI: 1.04–2.03] and had primary sex partner (1.63, 1.14–2.33) were more likely to be depressed. FSWs who did not use a condom during their last sex with the primary sex partner were less likely to be depressed (0.47, 0.31–0.71). Conclusion. Our study observed high level of depression and HIV risk behaviors among Chinese FSWs. Future interventions should integrate mental health services in comprehensive interventions to prevent depression among Chinese FSWs.

From conflict to partnership: growing collaboration between police and NGOs in countries with concentrated epidemics among key populations. J Int AIDS Soc 2016; 19:20939.

Abstract
Introduction Between September 2012 and December 2015, a series of national and regional consultations, aimed at resolving a persistent dynamic of conflict between law enforcement agencies (LEAs) and civil society organizations (CSOs) working on issues of access to HIV services in high-priority countries for people who use drugs have been organized by the HIV/AIDS Section of the United Nations Office on Drugs and Crime, the Joint United Nations Programme on HIV/AIDS, the Law Enforcement and HIV Network (LEAHN) and other international organizations. The aim of these consultations has been to understand, at a national and regional level, the key points of tension between police and CSOs and how to overcome these tensions to enhance access to and uptake of services by key populations, including people who inject drugs, sex workers, men who have sex with men and transgenders. This commentary briefly describes the methods, process, content and key outcomes of these consultations held across diverse number of countries and regions, including Africa, South East Asia, South Asia, Central Asia, Eastern Europe and Latin America. Discussion While the context varies, this paper highlights that there are commonalities that drive a persistent dynamic of conflict and therefore also common methods for resolution of conflict and forging partnerships. Both policing and CSOs have key sectoral responsibilities and reform agendas to implement to ensure that as an individual agency they are able to meet their obligations as partners in the HIV response. Using the key outcomes of discussions and recommendations from these consultations and drawing on existing literature, the objective of this paper is to present a preliminary model that roadmaps the critical path from resolution of conflict to partnership between LEAs and CSOs. Conclusions This paper seeks to highlight that critical resources are required to support ongoing development and harnessing of partnerships between LEAs and CSOs and argues that these resources should not just come from global HIV funding mechanisms but should be part of a more mainstreamed security sector reform agenda that understands the mutual benefits that programming for human rights–based policing reform would have on HIV, development and security.
