RESUMO
Background: Transgender women are disproportionately affected by gender-based violence (GBV). However, little is known about how they respond to GBV. Aims: This study aims to understand transgender women's response to GBV and identify barriers and facilitators in accessing healthcare and legal aid after experiencing the violence. Methods: We conducted a qualitative study between February to March 2020 in Phnom Penh, Cambodia. Data were collected through in-depth interviews with 20 transgender women aged between 21 and 49 who had experienced GBV or knew a peer who had experienced GBV. Thematic analysis was conducted for the coding process, and an inductive approach was used to develop a coding frame. Results: All participants had experienced at least one form of GBV in their lifetime, and most participants had experienced multiple forms of GBV. However, most of them did not seek any services from healthcare providers, law enforcement officers, or assistance for healthcare and legal aid from non-governmental organizations (NGOs). Participants reported the following barriers to access to GBV services: anticipated stigma, the internalized stigma, which resulted in shame and low self-esteem, a lack of knowledge on NGOs' services that can assist with healthcare and legal aid, the perception that mental health services were unavailable, a lack of social support, enacted stigma by the police, and the perceived healthcare cost. The participants reported social support and knowledge of NGOs' services as facilitators of access to GBV service. Social media and NGO staff were reported to be preferred sources of information. Participants wanted more effective law enforcement services, comprehensive healthcare catered to the unique transgender women's needs, and non-discriminating service providers. Discussion: Interventions to address GBV and improve the health outcomes of transgender women should involve creating an enabling environment for help-seeking with the partnership between NGOs and different sectors and building social support.
RESUMO
BACKGROUND: Maintaining oral health is essential for improving overall health of children living with HIV. Therefore, we evaluated the effectiveness of an oral health intervention for improving their oral and overall health. In addition, we examined their longitudinal association between changes in oral and overall health. METHODS: We conducted a 2-year randomized controlled trial involving children living with HIV in Cambodia. Children aged 3-15 years and their caregivers were randomly allocated either to the intervention (group A) or control (group B) arm. A second control arm (group C) included children without HIV. The group A children received oral health education sessions and practiced home-based daily care. RESULTS: In the baseline survey, 482 children participated (group A: n = 160, group B: n = 168, group C: n = 154), and 350 completed the endline survey. An interaction effect in teeth brushing duration was observed in children in group A relative to group B (AOR = 2.69, 95% CI: 1.37-5.31) and group C (AOR = 3.78, 95% CI: 1.70-8.40). Longitudinal associations were observed between changes in oral hygiene and overall health, as presented by alterations in dental caries in permanent teeth with viral load detection (adjusted odds ratio = 3.58, 95% CI: 1.10 - 11.73), in salivary flow quantity with the overall quality of life (ß = 0.07, 95% CI: < 0.01 - 0.13), as well as in dental caries, salivary pH, debris index with body mass index for age among group A children. CONCLUSIONS: Oral health intervention may improve oral care behaviors and potentially enhance overall health among children living with HIV in antiretroviral therapy in a resource-constrained setting. TRIAL REGISTRATION: ISRCTN 15177479.

BACKGROUND: Cambodia has achieved great success in tuberculosis (TB) control in the past decade. Nevertheless, people with TB are missed by the health systems at different stages of the care pathway. This programme review corroborated the care-seeking behaviours of people with TB and TB services availability and estimated the number of people completing each step of the TB disease and TB preventive treatment (TPT) care cascade. METHODS: Patient pathways and the care cascades for TB disease and TPT were constructed using data from the latest national TB prevalence survey, routine surveillance and programme, the global TB database and published studies. We also randomly selected TB survivors in the 2019 cohort to assess recurrence-free survival 1-year post-treatment. TPT care cascade was constructed for people living with HIV (PLHIV) and household contacts (children <5 years and all ages) of persons with bacteriologically-confirmed TB in 2019 and 2020. RESULTS: Nationally, 54% of those who exhibited TB symptoms sought initial care in the private sector. Overall, 93% and 58% of people with presumptive TB did not access a facility with TB diagnostic and treatment services, respectively, at the first point of care-seeking. Approximately 56% (95% CI 52% to 57%) of the 47 000 (95% CI 31 000 to 68 000) estimated TB cases in 2019 achieved recurrence-free survival. Among the estimated PLHIV in Cambodia, <30% completed TPT. Among children <5 years, 53% (95% CI 29% to 65%) (2019) and 67% (95% CI 36% to 80%) (2020) of those eligible for TPT completed the regimen successfully. In 2019 and 2020, 23% (95% CI 22% to 25%) and 54% (95% CI 50% to 58%) of the estimated household contacts (all ages) eligible for TPT completed the regimen successfully. CONCLUSION: There are significant gaps in care-seeking, coverage and access to TB services and TPT in Cambodia. Action plans to improve TB response have been co-developed with local stakeholders to address the gaps throughout the care cascades.

Background: HIV-positive children are at high risk for oral mucosal disorders. Additionally, their low immune status is associated with dental caries. However, little is known about how their dental caries and related risk factors, such as salivary flow, salivary pH level and oral health-related quality of life, differ from those of HIV-negative children. The study aimed to assess (1) dental caries and related risk factors in HIV-positive compared with HIV-negative children and (2) the association between these factors and HIV seropositive status in Phnom Penh, Cambodia. Methods: This was a cross-sectional study conducted as a baseline survey of a randomised controlled trial. The study setting was the National Pediatric Hospital's catchment area. The study population comprised 328 HIV-positive and 154 HIV-negative children aged 3-15 years and their caregivers. We collected clinical oral health data, questionnaire data to assess oral health-related quality of life and growth data. Results: The mean number of decayed, missing or filled permanent teeth (DMFT) and deciduous teeth (dmft) among HIV-positive children was 4.0 (SD 3.6) and 7.0 (SD 4.9), respectively. Among HIV-negative children, the respective values were 3.3 (SD 3.7) and 7.1 (SD 4.6). Living with HIV was positively associated with DMFT (adjusted OR 1.85, 95% CI 1.14 to 3.01) and salivary flow (ß=0.72, 95% CI 0.44 to 1.00) and negatively associated with salivary pH (ß=-0.13, 95% CI -0.24 to -0.02). However, HIV-positive status was not significantly associated with dmft or oral health-related quality of life. Conclusions: HIV-positive children had poorer oral health status regarding DMFT and salivary pH level. Specific strategies and further efforts are required to align their oral health status with that of HIV-negative children.

BACKGROUND: Stigma is a significant barrier to healthcare and a factor that drives the global burden of tuberculosis (TB). However, there is a scarcity of information on TB stigma in developing countries. We aimed to characterize, measure, and explore the determinants of TB stigma among people with TB in Cambodia. METHODS: We conducted a mixed-methods study between February and August 2019 using a triangulation convergent design-a cross-sectional survey (nâ =â 730) and nested in-depth interviews (nâ =â 31) among people with TB. Quantitative data were analyzed using descriptive statistics and generalized linear regression models. Qualitative transcripts were thematically analyzed. RESULTS: A total of 56% and 51% of participants experienced self-stigma and perceived stigma by the community, respectively. We found rural dwellers, knowledge of how TB is transmitted, and knowledge that anybody can get TB were associated with higher levels of self-stigma and perceived stigma by the community. Higher scores on knowledge of TB symptoms were inversely associated with both self-stigma and community stigma. Thematic analyses revealed accounts of experienced stigma, acts of intentional distancing and hiding TB diagnosis from others, and feelings of embarrassment and shame. CONCLUSIONS: Tuberculosis stigma was prevalent, suggesting a need for the incorporation of stigma-reduction strategies in the national TB responses. These strategies should be contextualized and developed through community engagement. Future research should continue to measure the levels and dimensions of TB stigma among people with TB through behavioral surveillance using standardized tools.
RESUMO
BACKGROUND AND OBJECTIVES: The effects of active case finding (ACF) models that mobilise community networks for early identification and treatment of tuberculosis (TB) remain unknown. We investigated and compared the effect of community-based ACF using a seed-and-recruit model with one-off roving ACF and passive case finding (PCF) on the time to treatment initiation and identification of bacteriologically confirmed TB. METHODS: In this retrospective cohort study conducted in 12 operational districts in Cambodia, we assessed relationships between ACF models and: 1) the time to treatment initiation using Cox proportional hazards regression; and 2) the identification of bacteriologically confirmed TB using modified Poisson regression with robust sandwich variance. RESULTS: We included 728 adults with TB, of whom 36% were identified via the community-based ACF using a seed-and-recruit model. We found community-based ACF using a seed-and-recruit model was associated with shorter delay to treatment initiation compared to one-off roving ACF (hazard ratio 0.81, 95% CI 0.68-0.96). Compared to one-off roving ACF and PCF, community-based ACF using a seed-and-recruit model was 45% (prevalence ratio (PR) 1.45, 95% CI 1.19-1.78) and 39% (PR 1.39, 95% CI 0.99-1.94) more likely to find and detect bacteriologically confirmed TB, respectively. CONCLUSION: Mobilising community networks to find TB cases was associated with early initiation of TB treatment in Cambodia. This approach was more likely to find bacteriologically confirmed TB cases, contributing to the reduction of risk of transmission within the community.
RESUMO
BACKGROUND: Cambodia is among the 30 countries in the world with the highest burden of tuberculosis (TB), and it is estimated that 40% of people with TB remain undiagnosed. In this study, we aimed to investigate the determinants of delayed diagnosis and treatment of TB in Cambodia. METHODS: This mixed-method explanatory sequential study was conducted between February and September 2019 in 12 operational districts in Cambodia. It comprised of a retrospective cohort study of 721 people with TB, followed by a series of in-depth interviews. We assessed factors associated with time to TB diagnosis and treatment initiation using Cox proportional hazards model. Subsequently, we conducted in-depth interviews with 31 people with TB purposively selected based on the time taken to reach TB diagnosis, sex, and residence. Transcripts were coded, and thematic analyses were performed. RESULTS: The median time from the onset of symptoms to TB diagnosis was 49 days (Interquartile range [IQR]: 21-112). We found that longer time to diagnosis was significantly associated with living in rural area (Adjusted hazards ratio [aHR] = 1.25; 95% confidence interval [CI]: 1.06-1.48); TB symptoms-cough (aHR: 1.52; 95% CI: 1.18-1.94), hemoptysis (aHR 1.32; 95% CI: 1.07-1.63), and night sweats (aHR: 1.24; 95% CI: 1.05-1.46); seeking private health care/self-medication (aHR: 1.23; 95% CI: 1.04-1.45); and higher self-stigma (aHR: 1.02; 95% CI: 1.01-1.03). Participants who received education level above the primary level were inversely associated with longer time to diagnosis (aHR: 0.78; 95% CI: 0.62-0.97). The median time from TB diagnosis to the initiation of treatment was two days (IQR: 1-3). The use of smear microscopy for TB diagnosis (aHR: 1.50; 95% CI: 1.16-1.95) was associated with longer time to treatment initiation. Seeking private health care and self-medication before TB diagnosis, lack of perceived risk, threat, susceptibility, and stigma derived qualitatively further explained the quantitative findings. CONCLUSIONS: TB diagnostic delay was substantial. Increasing public awareness about TB and consciousness regarding stigma, engaging the private healthcare providers, and tailoring approaches targeting the rural areas could further improve early detection of TB and narrowing the gap of missing cases in Cambodia.

BACKGROUND: Cambodia has made notable progress in the fight against tuberculosis (TB). However, these gains are impeded by a significant proportion of undiagnosed cases. To effectively reach people with TB, active case-finding (ACF) strategies have been adopted by countries affected by the epidemic, including Cambodia, alongside passive case finding (PCF). Despite increased efforts to improve case detection, approximately 40% of TB cases in Cambodia remained undiagnosed in 2018. In Cambodia, several community-based TB ACF modalities have been implemented, but their effectiveness has yet to be systematically assessed. METHODS: This pragmatic cluster randomized controlled trial will be conducted between December 2019 and June 2021. We will randomize eight operational districts (clusters) in seven provinces (Kampong Cham, Kampong Thom, Prey Veng, Thbong Khmum, Kampong Chhnang, Kandal, and Kampong Speu) to either the control group (PCF) or the intervention groups (ACF using a seed-and-recruit model, ACF targeting household and neighborhood contacts, and ACF targeting persons aged ≥ 55 years using mobile screening units). The primary endpoints will be TB case notification rates, additionality, and cumulative yield of TB cases. The secondary endpoints include treatment outcomes, the number needed to screen to find one TB case, and cost-effectiveness outcome measures. We will analyze the primary and secondary endpoints by intention to treat. We will compare cluster and individual-level characteristics using Student's t test and hierarchical or mixed-effect models to estimate the ratio of these means. The incremental cost-effectiveness ratio per disability-adjusted life year averted will also be considered as a benchmark to determine whether the interventions are cost-effective. DISCUSSION: This study will build an evidence base to inform future scale-up, implementation, and sustainability of ACF strategies in Cambodia and other similar settings. Implementation of this study will also complement TB control strategies in Cambodia by conducting ACF in operational districts without active interventions to find TB cases currently. Those who are ill and might have TB will be promptly screened, diagnosed, and linked to care. Early diagnosis and treatment initiation will also benefit their community by interrupting transmission and prevent further infections. The experience gained from this project will inform future attempts in conducting pragmatic trials in low-resource settings. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04094350.
