Engagement Along the PrEP Care Continuum Among Men Who Have Sex with Men in China: A Systematic Review and Meta-analysis.

Pre-exposure prophylaxis (PrEP), including daily oral, on-demand, and long-acting injectable (LAI), is a promising HIV prevention intervention for men who have sex with men (MSM). We conducted a systematic review on engagement with the PrEP continuum among MSM in China. A total of 756 studies were initially identified and 36 studies were included (N = 26,021). In the 20 studies (N = 13,886) examining PrEP awareness, 32.4% (95% CI: 25.1-40.7) of MSM were aware of PrEP. In the 25 studies (N = 18,587) examining willingness, 54.5% (95% CI: 41.9-66.5) MSM indicated they were willing to use PrEP. The pooled prevalence of PrEP uptake from 9 studies (N = 6,575) was 4.9% (95% CI: 1.4-15.8%), while pooled estimates of adequate adherence from five studies (N = 2,344) among MSM on PrEP was 40.7% (95% CI: 20.0-65.2%). Subgroup analyses suggested studies conducted after 2015 (versus before) tended to report higher awareness and uptake. Awareness was highest for daily oral PrEP, followed by on-demand, and LAI PrEP; willingness to use was highest for LAI PrEP. The operationalization of willingness and adherence constructs varied across studies and complicated the interpretation of pooled estimates. This review revealed gaps in the PrEP care continuum among MSM in China, with relatively low awareness and uptake (in contrast to willingness and adherence) as the major potential barriers to widespread implementation and the need for a unified approach to defining and measuring PrEP outcomes.

Discrimination and hypertension among a diverse sample of racial and sexual minority men living with HIV: baseline findings of a longitudinal cohort study.

Racial and sexual orientation discrimination may exacerbate the double epidemic of hypertension (HTN) and HIV that affects men of color who have sex with men (MSM). This was a cross-sectional analysis of African American, Asian American, Native Hawaiian, or Pacific Islander (NHPI) MSM living with HIV (PLWH) cohort in Honolulu and Philadelphia. Racial and sexual orientation discrimination, stress, anxiety, and depression were measured with computer-assisted self-interview questionnaires (CASI). We examined the associations between racial and sexual orientation discrimination with hypertension measured both in the office and by 24-h ambulatory blood pressure monitoring (ABPM) using multivariable logistic regression. Sixty participants (60% African American, 18% Asian, and 22% NHPI) completed CASIs and 24-h ABPM. African American participants (80%) reported a higher rate of daily racial discrimination than Asian American (36%) and NHPI participants (17%, p < 0.001). Many participants (51%) reported daily sexual orientation discrimination. Sixty-six percent of participants had HTN by office measurement and 59% had HTN by 24-h ABPM measurement. Participants who experienced racial discrimination had greater odds of having office-measured HTN than those who did not, even after adjustment (Odds Ratio 5.0 (95% Confidence Interval [1.2-20.8], p = 0.03)). This association was not seen with 24-h ABPM. Hypertension was not associated with sexual orientation discrimination. In this cohort, MSM of color PLWH experience significant amounts of discrimination and HTN. Those who experienced racial discrimination had higher in-office blood pressure. This difference was not observed in 24-h APBM and future research is necessary to examine the long-term cardiovascular effects.

Examining biopsychosocial predictors of risk for cognitive impairment among a racially diverse sample of men who have sex with men living with HIV.

Background: Cognitive decline among people living with HIV (PLWH) is growing concern as world populations become increasing older including higher proportions of PLWH. It is vitally important to understand psychosocial predictors of age-related cognitive decline men who have sex with men (MSM) living with HIV. Objectives: The current study seeks to examine psychosocial risk factors the contribute to the risk of age-related cognitive impairment as measured by Cardiovascular Risk Factors, Aging, and Incidence of Dementia (CAIDE) score in a racially diverse sample of MSM living with HIV. Design: The present analysis utilizes data from the baseline (n = 196) and 6-month follow-up (n = 135) time points of a longitudinal cohort study of PLWH. Methods: Using a self-report survey, we examine the associations between psychosocial predictors (e.g. trauma, mental health, chronic pain, sleep disturbance, etc.) and risk of dementia using the CAIDE risk score. Analyses include linear and logistic regression. Results: In adjusted model stress, chronic pain, Black racial identity, and having a sexual identity that is bisexual or another category are all positively associated with CAIDE scores. Childhood sexual abuse history was negatively associated with CAIDE scores indicating a protective effect. Sleep disorder has a positive association with CAIDE scores after adjusting for the baseline CAIDE scores. Conclusion: These results indicate modifiable correlates of cognitive risk (stress and chronic pain). Interventions should seek to address these comorbid factors including the consideration of minority stress and stigma. Interventions should seek to reach Black and bisexual men living with HIV, including possible cultural tailoring to interventions and messaging. Lastly, future research should examine the impact of variation within childhood sexual abuse histories to better understand their association with cognitive impairment later in life. This may include considering the nature, severity, and potential treatment of trauma symptoms.

What makes middle-aged or older people who have HIV more likely to have memory problems later in life? We asked a racially diverse group of gay and bisexual men who have HIV. Why was the study done? Older people are becoming a larger portion of our communities including older people living with HIV. It's important to understand what makes older people more likely to have memory problems as they age including older people living with HIV. What did the researchers do? We asked 196 middle-aged and older adults who have HIV to answer questions about their health including things that we know might make them more likely to have memory problems later in life. What did the researchers find? We found that having more stress or reoccurring pain was related to being more likely to have memory problems later in life. People who have trouble sleeping were more likely to have memory problems later in life. We also found that Black people were more likely to have memory problems later in life. People who had been abused sexually as children were less likely to have memory problems later in life. What do the findings mean? These findings help us understand things that may make someone more likely to have memory problems later in life. These include things that could be changed like reoccurring pain and troubles sleeping. It also highlighted that Black people may need more support to prevent memory problems later in life.

Health Service Utilization and Its Associations with Depression and Sexual Risk Behaviors Among Transgender Women in Shanghai, China.

Purpose: Given the limited research on health care utilization among transgender women in China, we described the use of primary health care and gender-affirming health care, and the associations between utilization of gender-affirming health care and depression and sexual risk behaviors. Methods: We conducted a cross-sectional survey in 2017 among a purposive sample of transgender women in Shanghai, China (N=199). We examined correlates of health care utilization and its association with depression and sexual risk behaviors with Chi-square (χ2), Fisher's exact tests, and analysis of variance. Results: The majority of the sample (78.5%) only had physician appointments when having an illness, while about one-fifth of the sample had physician appointments for yearly checkups. Nineteen out of 199 participants (9.5%) received gender-affirming surgery, among which only five used hormone therapy prescribed by a doctor (26.3%). Receiving some form of gender-affirming surgery was associated with higher depression scores [Welch's F(2, 12.22)=4.16, p=0.04], engagement in sex work (p=0.001), having 7 or more male sexual partners in the last 30 days (p=0.003), lifetime unprotected sex with a man (p=0.050), and unprotected sex with a main partner (p=0.043). Compared with transgender women who received both breast augmentation and vulvo-vaginoplasty (mean=5.86), those who received breast augmentation only (mean=12.33) scored higher on depression (p=0.04). Conclusions: Access to gender-affirming health care is low among transgender women in this study. The utilization of gender-affirming surgery is associated with depression and sexual risk behaviors. Findings suggest China should establish national guidelines on transgender-related health care and set up more clinics to provide consultation and services for the transgender population in China.

Depression as a mediator between intimate partner violence (IPV) and CD4 cell count among men who have sex with men (MSM) living with HIV in China.

Intimate partner violence (IPV) is associated with adverse mental and physical outcomes among men who have sex with men (MSM) living with HIV. Few studies focus on psychological IPV, such as verbal threats. This study examined the associations between different forms of IPV and depression and CD4+ cell count, with depression as a mediator for the association between IPV and CD4+ cell count. Data for these analyses were derived from a larger cross-sectional study on HIV-HCV co-infection among MSM in Shanghai, China (N = 1623). We estimated the average causal mediation effects (ACME) and average direct effects (ADE) through three steps. About 16% of participants experienced IPV, with forced sex (7%), verbal threats (5%), and thrown objects (4%) being most common. Verbal threats showed the strongest link with depression and low CD4+ cell count. Depression fully mediated the relationship between verbal abuse and low CD4+ cell count, suggesting it as a potential pathway between psychological IPV and poorer HIV-related health outcomes. More research on psychological IPV is warranted to examine its health impacts. Mental health could be a potential focus of intervention to enhance HIV-related health outcomes among MSM with IPV experience.

Dating violence prevalence and risk factors among adolescents (14-19 years) in urban public schools in Panama.

Background: Adolescent dating violence (ADV) can have lasting effects on youth's well-being and development. However, few studies in Latin America have described its prevalence and risk factors for having experienced ADV. Methods: We conducted a multisite, cross-sectional study using two-stage cluster sampling among adolescents (14-19 years) attending public high schools in the urban districts of Panama, San Miguelito, Colón, and Arraiján/La Chorrera from 2015 to 2018 (N = 2469). All completed a tablet-based, self-administered questionnaire. Random effects logistic regression was used to identify risk factors for each ADV type among adolescent boys and girls separately. Findings: Participants reported experiencing a range of ADV at least once (girls: emotional 61.6%, physical 7.9%, sexual 21.0%; boys: emotional 73.4%, physical 24.1%, sexual 28.9%). In adjusted models, participants with a history of sexual intercourse had greater odds of ADV than those without such history across types (boys: emotional and sexual; girls: emotional, physical, and sexual). Additionally, participants who reported three or more romantic partners in the past year had greater odds of ADV than those with one partner (boys: emotional, physical; girls: physical). Girls with an earlier sexual debut (≤14 years vs ≥15 years) had greater odds of reporting ADV (emotional and sexual violence). No associations were found between reporting dating violence survival and the sex of romantic partners in the past year or the age of the current/most recent sex partner. Interpretation: This study reveals a high prevalence of ADV among adolescents in urban public schools in Panama. These findings support the need for program implementation to address ADV. Funding: Funding to undertake this study was acquired from Panama's Ministry of Economics and Finance, project number 009044.049.

Detection of Clade 2.3.4.4b Avian Influenza A(H5N8) Virus in Cambodia, 2021.

In late 2021, highly pathogenic avian influenza A(H5N8) clade 2.3.4.4b viruses were detected in domestic ducks in poultry markets in Cambodia. Surveillance, biosafety, and biosecurity efforts should be bolstered along the poultry value chain to limit spread and infection risk at the animal-human interface.

H7N9 bearing a mutation in the nucleoprotein leads to increased pathology in chickens.

The zoonotic H7N9 avian influenza (AI) virus first emerged in 2013 as a low pathogenic (LPAI) strain, and has repeatedly caused human infection resulting in severe respiratory illness and a mortality of ~39% (>600 deaths) across five epidemic waves. This virus has circulated in poultry with little to no discernible clinical signs, making detection and control difficult. Contrary to published data, our group has observed a subset of specific pathogen free chickens infected with the H7N9 virus succumb to disease, showing clinical signs consistent with highly pathogenic AI (HPAI). Viral genome sequencing revealed two key mutations had occurred following infection in the haemagglutinin (HA 226 L>Q) and nucleoprotein (NP 373 A>T) proteins. We further investigated the impact of the NP mutation and demonstrated that only chickens bearing a single nucleotide polymorphism (SNP) in their IFITM1 gene were susceptible to the H7N9 virus. Susceptible chickens demonstrated a distinct loss of CD8+ T cells from the periphery as well as a dysregulation of IFNγ that was not observed for resistant chickens, suggesting a role for the NP mutation in altered T cell activation. Alternatively, it is possible that this mutation led to altered polymerase activity, as the mutation occurs in the NP 360-373 loop which has been previously show to be important in RNA binding. These data have broad ramifications for our understanding of the pathobiology of AI in chickens and humans and provide an excellent model for investigating the role of antiviral genes in a natural host species.

The Cumulative Influence of Perceived Discrimination, Stress, and Coping Responses on Symptoms of Depression Among Young African American Mothers.

BACKGROUND: African American women have an elevated risk for experiencing depressive symptoms, and discrimination, stress, and coping contribute to symptoms of depression. AIMS: We aimed to examine the associations between discrimination, stress, and coping on symptoms of depression among young African American mothers. METHODS: In this retrospective study, we utilized a hierarchical linear regression to explore the effects of perceived racial discrimination, stress, and general and discrimination-related coping responses on depressive symptoms in a sample of African American mothers (N = 250). The data were drawn from the Intergenerational Impact of Genetic and Psychological Factors on Blood Pressure study (InterGEN), a study conducted between 2014 and 2019 and based in Connecticut. RESULTS: After accounting for maternal age, level of education, and income, greater perceived racial discrimination (p = .03), higher levels of stress (p < .001), greater engagement in avoidance coping (p < .001), and use of passive coping responses to discrimination (p = .04) were uniquely associated with increased depressive symptoms. Other forms of coping, specifically, problem-solving and support seeking, did not appear to influence depressive symptoms in this sample. CONCLUSION: The findings highlight the negative impact of discrimination, heightened stress, and maladaptive coping on the emotional health of young African American mothers.

Australia as a global sink for the genetic diversity of avian influenza A virus.

Most of our understanding of the ecology and evolution of avian influenza A virus (AIV) in wild birds is derived from studies conducted in the northern hemisphere on waterfowl, with a substantial bias towards dabbling ducks. However, relevant environmental conditions and patterns of avian migration and reproduction are substantially different in the southern hemisphere. Through the sequencing and analysis of 333 unique AIV genomes collected from wild birds collected over 15 years we show that Australia is a global sink for AIV diversity and not integrally linked with the Eurasian gene pool. Rather, AIV are infrequently introduced to Australia, followed by decades of isolated circulation and eventual extinction. The number of co-circulating viral lineages varies per subtype. AIV haemagglutinin (HA) subtypes that are rarely identified at duck-centric study sites (H8-12) had more detected introductions and contemporary co-circulating lineages in Australia. Combined with a lack of duck migration beyond the Australian-Papuan region, these findings suggest introductions by long-distance migratory shorebirds. In addition, on the available data we found no evidence of directional or consistent patterns in virus movement across the Australian continent. This feature corresponds to patterns of bird movement, whereby waterfowl have nomadic and erratic rainfall-dependant distributions rather than consistent intra-continental migratory routes. Finally, we detected high levels of virus gene segment reassortment, with a high diversity of AIV genome constellations across years and locations. These data, in addition to those from other studies in Africa and South America, clearly show that patterns of AIV dynamics in the Southern Hemisphere are distinct from those in the temperate north.

Exploratory Study of NPC-0501 Trial: Optimal Cisplatin Dose of Concurrent and Induction/Adjuvant Chemotherapy for Locoregionally Advanced Nasopharyngeal Carcinoma.

PURPOSE: The current recommendation for patients with locoregionally advanced nasopharyngeal carcinoma (NPC) is cisplatin-based induction chemotherapy (IC) or adjuvant chemotherapy (AC) plus concurrent chemoradiotherapy (CRT). However, data on the optimal platinum doses for each phase of combined regimens are lacking. EXPERIMENTAL DESIGN: 742 patients with NPC in the NPC-0501 trial treated with CRT plus IC/AC and irradiated with intensity-modulated radiotherapy (IMRT) were analyzed. The optimal platinum dose to achieve the best overall survival (OS) in the concurrent and induction/adjuvant phases was studied. RESULTS: Evaluation of the whole series shows the optimal platinum dose was 160 mg/m2 in the concurrent and 260 mg/m2 in the induction/adjuvant phase. Repeating the analyses on 591 patients treated with cisplatin throughout (no replacement by carboplatin) confirmed the same results. The cohort with optimal platinum doses in both phases had better OS than the cohort suboptimal in both phases (stage III: 90% vs. 75%; stage IVA-B: 80% vs. 56%, at 5-year). Multivariable analyses confirmed optimal platinum doses in both phases versus suboptimal dose in each phase are significant independent factors for OS, with HR of 0.61 [95% confidence interval (CI), 0.41-0.91] and 0.67 (95% CI, 0.48-0.94), respectively. Treatment sequence was statistically insignificant after adjusting for platinum doses. CONCLUSIONS: Both concurrent and IC/AC are needed for locoregionally advanced NPC, even for patients irradiated by IMRT; the concurrent platinum dosage could be set at ≥160 mg/m2 when coupled with adequate induction/adjuvant dosage at ≥260 mg/m2 (or at least ≥240 mg/m2). To achieve these optimal dosages, IC-CRT at conventional fractionation is favored.

Health-care access and utilization among HIV-infected men who have sex with men in two Chinese municipalities with or without lockdown amidst early COVID-19 pandemic.

City lockdown is critical to successfully contain the COVID-19 pandemic. The impact of lockdown and COVID-19 pandemic on healthcare among vulnerable population has yet to be explicated. A cross-sectional survey was conducted among HIV-infected men who have sex with men (MSM) in Wuhan with city lockdown and Shanghai without lockdown, and healthcare interruptions were evaluated and compared. A logistic regression analysis was employed to examine associates of HIV-related healthcare interruptions and compromised mental health. Compared to participants in Shanghai (N = 440), HIV-infected MSM in Wuhan (N = 503) had significantly higher proportion of untimely availability of antiretroviral drugs (ARVs) (20.6% vs. 8.4%), obtaining ARVs from outside institutions (29.1% vs. 8.1%), postponed non-AIDS treatment (6.4% vs. 2.8%) and untimely follow-up appointments (33.4% vs. 14.5%). HIV-related healthcare interruptions were positively associated with lockdown (OR = 4.89, 95% CI: 3.49-6.85) and non-local residence (OR = 1.91, 95% CI: 1.37-2.64). Compromised mental health, including insomnia and generalized anxiety disorders, was associated with non-local residence (OR = 1.35, 95% CI: 1.01-1.81) and healthcare interruptions (OR = 1.34, 95% CI: 1.01-1.79). HIV-infected MSM are vulnerable to healthcare interruptions and mental health problems during the COVID-19 pandemic, underscoring the need for tailored intervention strategies to minimize deleterious health consequences.

Living While Black, Gay, and Poor: The Association of Race, Neighborhood Structural Disadvantage, and PrEP Utilization Among a Sample of Black Men Who Have Sex With Men in the Deep South.

Utilizing the Andersen Healthcare Utilization Model, we examined the role of neighborhood context on pre-exposure prophylaxis (PrEP) utilization among a sample of Black men who have sex with men (MSM) residing in a medium-sized city in the Deep South. Data were derived from a sample of 142 Black MSM aged 18-64 years who were eligible for PrEP from a community-based study known as "ACCELERATE!" We used multilevel structural equation modeling to assess PrEP use. Social support, sexual risk, and health care access were predictive of PrEP use. Notably, residing in a neighborhood with concentrated poverty was associated with decreased PrEP use. Our findings reveal neighborhood structural disadvantage is associated with decreased PrEP use among Black MSM, after adjusting of individual-level sociodemographic characteristics. There is an urgent need to develop HIV prevention interventions and programs that explicitly address structural-level factors to eliminate racial/ethnic differences in HIV.

In Vitro and In Vivo Characterization of a Pigeon Paramyxovirus Type 1 Isolated from Domestic Pigeons in Victoria, Australia 2011.

Significant mortalities of racing pigeons occurred in Australia in late 2011 associated with a pigeon paramyxovirus serotype 1 (PPMV-1) infection. The causative agent, designated APMV-1/pigeon/Australia/3/2011 (P/Aus/3/11), was isolated from diagnostic specimens in specific pathogen free (SPF) embryonated eggs and was identified by a Newcastle Disease virus (NDV)-specific RT-PCR and haemagglutination inhibition (HI) test using reference polyclonal antiserum specific for NDV. The P/Aus/3/11 strain was further classified as PPMV-1 using the HI test and monoclonal antibody 617/161 by HI and phylogenetic analysis of the fusion gene sequence. The isolate P/Aus/3/11 had a slow haemagglutin-elution rate and was inactivated within 45 min at 56 °C. Cross HI tests generated an R value of 0.25, indicating a significant antigenic difference between P/Aus/3/11 and NDV V4 isolates. The mean death time (MDT) of SPF eggs infected with the P/Aus/3/11 isolate was 89.2 hr, characteristic of a mesogenic pathotype, consistent with other PPMV-1 strains. The plaque size of the P/Aus/3/11 isolate on chicken embryo fibroblast (CEF) cells was smaller than those of mesogenic and velogenic NDV reference strains, indicating a lower virulence phenotype in vitro and challenge of six-week-old SPF chickens did not induce clinical signs. However, sequence analysis of the fusion protein cleavage site demonstrated an 112RRQKRF117 motif, which is typical of a velogenic NDV pathotype. Phylogenetic analysis indicated that the P/Aus/3/11 isolate belongs to a distinct subgenotype within class II genotype VI of avian paramyxovirus type 1. This is the first time this genotype has been detected in Australia causing disease in domestic pigeons and is the first time since 2002 that an NDV with potential for virulence has been detected in Australia.

Associations between social determinants of health, perceived discrimination, and body mass index on symptoms of depression among young African American mothers.

PURPOSE: The association between symptoms of depression and risks for cardiovascular disease (CVD) remains equivocal for African American (AA) mothers. We examined the association between social determinants of health (perceived discrimination), and cardiovascular risk (BMI) on symptoms of depression in a sample of young AA mothers. METHODS: Secondary data from 219 adult AA mothers between the ages of 21 and 46 with an average BMI of 29.8 and yearly family income of $14,999 were analyzed using a latent growth model that evaluated four time points to assess changes in symptoms of depression. RESULTS: Initial BMI was significantly associated with initial symptoms of depression (b = 0.12, p = .019). Perceived discrimination (unfair treatment) was associated with higher initial symptoms of depression (b = 1.14, p = .017). CONCLUSION: The findings suggest that elevated BMI and perceived discrimination are associated with higher reported symptoms of depression among young, socioeconomically disadvantaged AA mothers. These results advance the scientific understanding of young AA mothers' risk for symptoms of depression and CVD by elucidating the impact of perceived discrimination and social experiences on mental health. Further studies of SDoH and CVD risk factors and perceived racism and depression are needed to shed light on the long-term mental health impact on AA mothers and their children.

Association of HIV infection with metabolic syndrome among normal or underweight young adults: evidence from the CHART cohort.

Metabolic syndrome (MS) is common among obese people. Little is known about the magnitude and characteristics of MS in people living with HIV (PLWH) in Asian countries in general and China in particular. Using baseline data collected between February 2017 through January 2020 from the Comparative HIV and Aging Research in Taizhou (CHART) cohort in China, we examined MS among 2,227 PLWH and 5,264 matched people without HIV, respectively. MS was defined using the criteria set forth by the International Diabetes Federation (IDF). Approximately 76.7% of PLWH had body mass index (BMI) < 24.0 kg/m2, significantly higher than people without HIV (50.3%). Among participants with BMI < 24.0 kg/m2, PLWH had a significantly higher prevalence of MS than people without HIV (20.6% vs. 14.5%; aOR: 1.41, 95% CI: 1.19-1.68) overall, and at an age of 18-29 (10.4% vs. 3.4%, aOR: 3.49, 95% CI: 1.99-6.11) and 30-44 years (17.3% vs. 8.5%, aOR: 2.03, 95% CI: 1.47-2.81), respectively. Among participants with BMI ≥ 24.0 kg/m2, MS prevalence was not significantly different between PLWH and people without HIV overall, but significantly lower in PLWH than people without HIV for those aged over 60 years (65.9% vs. 77.8%, aOR: 0.53, 95% CI: 0.32-0.88). Among PLWH, MS was significantly associated with older age and higher CD4 cell count, and with stavudine (d4T) use only in the group of BMI < 24.0 kg/m2. Our finding is indicative of a relatively higher risk for early onset of MS among HIV-infected young adults with lower BMI. Research is needed to elucidate the pathogenic mechanism for MS among PLWH.

Intimate Partner Violence Among Chinese Transwomen: Associations With Sexual Risk Behaviors and HIV Testing.

BACKGROUND: Intimate partner violence (IPV) is an emerging risk factor for HIV infection. Given the high vulnerability of and limited research on transwomen in China, we described IPV, sexual risk behaviors, HIV, and sexually transmitted infection (STIs) testing rates and results, and investigated the pathways that link IPV to HIV infection among this population. METHODS: We conducted a cross-sectional survey and collected blood samples for HIV and syphilis testing among transwomen in Shanghai, China (n = 199). With logistic regression, we examined sexual risk behaviors and HIV/STI testing history among participants with and without IPV experience. RESULTS: More than half of the respondents reported IPV (57.3%), and the prevalence of unprotected sex ranged from 51.9% (with sex workers) to 87.8% (oral sex); 85.9% had ever tested for HIV and 49.3% for other STIs. Self-reported positivity results were as follows: HIV (2.3%), herpes simplex virus type 2 (8.3%), gonorrhea (18.8%), and syphilis (17.8%). Laboratory-confirmed positivity values were 5.0% for HIV and 6.5% for syphilis. Respondents with a history of IPV were significantly less likely to report HIV testing in the past 12 months (adjusted odds ratio, 0.20; 95% confidence interval, 0.10-0.38). CONCLUSIONS: Transwomen self-reported a high prevalence of IPV, which was related to a lower probability of HIV testing. The prevalence of HIV and other STIs was lower than reported in previous studies of Chinese transwomen, whereas the HIV/STI testing rates were higher. Findings suggest transwomen in China are at risk for IPV and need enhanced HIV prevention services to promote HIV testing in an IPV setting.

Effectiveness of an Automated Error Checking and Feedback System to Improve Text Message Reporting for Disease Surveillance in Viet Nam.

Purpose: Viet Nam currently relies on a manual paper-based system to track and monitor 28 major infectious diseases. This inefficient system takes 2 or more months to complete. Method: We designed and pilot tested the use of text messaging to report certain infectious disease symptoms in rural areas of northern Viet Nam. The project was divided into three 6-month phases carried out in two provinces. The current analysis focuses on the implementation of a two-way feedback system between Phases II and III, which aims at (1) evaluating whether this system improves efficiency by determining the number of correctly (vs. incorrectly) formatted text messages; (2) assessing this system's influence on accuracy by comparing text messages with their respective official paper-based documented forms; and (3) determining whether the amount of information required to report through text messages influences the efficiency and accuracy of the text messages. Results: Between Phases II and III, results revealed a significant improvement in correctly formatted texts in comparison to incorrectly formatted texts. As the number of fields required to report increased, the number of correctly formatted texts (efficiency) as well as the number of matched text messages (accuracy) decreased. Conclusion: Our research demonstrates that an automated error bidirectional feedback system can significantly improve both the efficiency and accuracy of a Short Message Service-based method for disease surveillance. Also, our data may suggest that two-way communication has better engaged health care staff to follow reporting protocols as well as to maintain accuracy from their clinic's own data.

Detection of highly pathogenic avian influenza in Sekong Province Lao PDR 2018-Potential for improved surveillance and management in endemic regions.

Significant global efforts have been directed towards understanding the epidemiology of highly pathogenic avian influenza (HPAI) across poultry production systems and in wild-bird reservoirs, yet understanding of disease dynamics in the village poultry setting remains limited. This article provides a detailed account of the first laboratory-confirmed outbreak of HPAI in the south-eastern provinces of Lao PDR, which occurred in a village in Sekong Province in October 2018. Perspectives from an anthropologist conducting fieldwork at the time of the outbreak, clinical and epidemiological observations by an Australian veterinarian are combined with laboratory characterization and sequencing of the virus to provide insights about disease dynamics, biosecurity, outbreak response and impediments to disease surveillance. Market-purchased chickens were considered the likely source of the outbreak. Observations highlighted the significance of a-lack-of pathognomonic clinical signs and commonness of high-mortality poultry disease with consequent importance of laboratory diagnosis. Sample submission and testing was found to be efficient, despite the village being far from the national veterinary diagnostic laboratory. Extensively raised poultry play key roles in ritual, livelihoods and nutrition of rural Lao PDR people. Unfortunately, mass mortality of chickens due to diseases such as HPAI and Newcastle disease (ND) imposes a significant burden on smallholders in Lao PDR, as in most other SE Asian countries. We observed that high mortality of chickens is perceived by locals as a new 'normal' in raising poultry; this sense of it being 'normal' is a disincentive to reporting of mortality events. Establishing effective people-centred disease-surveillance approaches with local benefit, improving market-biosecurity and veterinary-service support to control vaccine-preventable poultry diseases could all reduce mass-mortality event frequency, improve veterinary-producer relationships and increase the likelihood that mortality events are reported. Priority in each of these aspects should be on working with smallholders and local traders, appreciating and respecting their perspectives and local knowledge.

Do the same socio-demographic variables predict testing uptake and sero-status? HIV and syphilis among an observational sample of Chinese men who have sex with men in Shanghai, China.

HIV and syphilis are pronounced among men who have sex with men (MSM) in China and often occur as co-infections, while testing remains low. Few studies examine common predictors across these outcomes. This observational venue-based sample of 546 MSM in Shanghai, China used a common set of psychosocial predictors to construct logistic models for the outcomes (HIV non-testing, syphilis non-testing, HIV sero-status, and syphilis sero-status). Fifty-seven (10.7%) participants tested positive for HIV, 126 (23.5%) for syphilis, and 33% of HIV-positive participants had a co-infection. Non-sex working MSM had consistently higher odds of HIV and syphilis non-testing (OR= 2.2, 95% CI 1.4-3.5, p < 0.001; OR = 2.4, 95, 95% CI 1.5-3.8, p < 0.001, respectively) compared to 'money boy' sex workers. Participants with a 0 score on HIV knowledge had 4.1 times (95% CI 1.4-12.5, p = 0.01) the odds of reporting HIV non-testing, 6.0 (95% CI 1.96-18.5, p < 0.01) times the odds of reporting non-testing for syphilis, and 8.44 times (95% CI 1.19-59.7, p = 0.03) the odds of testing positive for HIV, compared to a score of 8. The results highlighted the importance of integrating HIV/syphilis education and promoting testing for both HIV and syphilis among all sub-groups of MSM in China.
