RESUMEN
PURPOSE: We aimed to assess knowledge, attitudes, and perceived barriers among health care professionals (HCPs), policymakers, and regulators in Vietnam related to opioid therapy for cancer pain. METHODS: We conducted a cross-sectional study in Vietnam from June to August 2022. Participants completed a questionnaire on their demographic characteristics, knowledge and attitudes toward opioid therapy, and barriers to accessing opioids for cancer pain. RESULTS: Two hundred seven HCPs and 15 policymakers/regulators completed the questionnaire. Poor knowledge about opioids in cancer pain was found in 63.3% of HCPs and 80.0% of policymakers/regulators. Poor knowledge was associated with a lack of training in cancer pain management or palliative care (PC; prevalence ratio [PR], 1.14 [95% CI, 1.04 to 1.24]). Negative attitudes toward opioid therapy in cancer pain were held by 64.7% of HCPs and 80.0% of policymakers/regulators. Negative attitudes were associated with the unavailability of oral morphine in the workplace (PR, 1.10 [95% CI, 1.01 to 1.20]). The most common major barriers reported were the absence of national policy on pain management and PC (34.7%), inadequate training in opioid use for cancer pain (33.8%), lockdown of health facilities during the COVID-19 pandemic (32.4%), limited opioid availability in local health facilities (32.4%), and excessively restrictive regulation of opioid dispensing in pharmacies (32.4%). CONCLUSION: This study found a knowledge deficit and negative attitudes toward opioid therapy for cancer pain among HCPs and policymakers/regulators. Improving education and training in opioid therapy is essential. Recognizing major barriers can guide strategies to enhance safe opioid accessibility for cancer pain management in Vietnam.

BACKGROUND: Safe Spaces are a harm reduction approach commonly utilised in nightlife and festival settings to address alcohol and other drug-related harms. Despite increasing use, there has been little independent evaluation of safe space programs. This study aimed to explore (1) program user satisfaction with and use of a safe space program implemented in Sydney, Australia (The Take Kare Safe Space (TKSS)), and (2) the strengths and weaknesses of TKSS from the perspective of key stakeholders. METHODS: Semi-structured, in-depth, interviews lasting between 30 min to 1 h were conducted with 38 key program stakeholders, including staff from police (n = 4), ambulance (n = 4), a local hospital accident and emergency room (n = 4), local council (n = 2), city 'rangers' (n = 2), the TKSS program (n = 4), licensed venues and other nightlife service providers (n = 4), and program users (n = 14). Purposive sampling was used to identify key stakeholders to participate in interviews. RESULTS: Stakeholders stated that the TKSS program had a number of core benefits, including that it filled a service gap in nightlife settings; improved the efficiency and effectiveness of emergency services and other stakeholders operating in nightlife precincts; provided welfare services through proactive and non-judgmental interventions; and facilitated a means to de-escalate conflict without engaging police. Perceived weaknesses of the program included a lack of public awareness about the program; staff and volunteer levels; and misunderstandings regarding the scope and function of the TKSS program by some stakeholders. CONCLUSION: This study demonstrates the complex relationships that exist around the delivery of harm reduction in nightlife settings. In particular, it highlights the relative lack of servicing of public nightlife settings and the value of safe spaces/peer-to-peer safety ambassador programs in linking up care and filling this service gap. Further, it documents the extended benefit across key stakeholder groups of delivering proactive and non-judgemental harm reduction services and, in doing so, provides critical evidence around their efficacy in reducing AOD-related harms in the night-time economy.

Background: This study aims to examine the psychometric properties of the nine-item Patient Health Questionnaire (PHQ-9) and assess the relationship between the PHQ-9 domain and demographics and health behaviors in Vietnamese people. Materials and Methods: The PHQ9 was administered to 899 participants. Exploratory factor and reliability analyses were performed. Tobit regression and Ordered logistic regression were further performed to determine factors associated with the PHQ-9 score and characteristics of depression. Results: The 2-factor model of PHQ-9, including factor 1 "Somatic" and factor 2 "Cognitive/Affective," showed good psychometric properties. The Cronbach's alpha value showed high internal consistency in two factors (0.84 and 0.80, respectively). Gender, health behavior exercising, drinking, and health status had associations with both factors of the PHQ-9 model. Conclusion: The PHQ-9 scale is a valid and reliable instrument to assess depression in the Vietnam population. This scale can be a useful screening tool for depression; however, further validation studies in other populations are required.
RESUMEN
Safe spaces are increasingly utilized to reduce alcohol-related harm, violence, crime and improve public safety in nightlife settings. This study aimed to determine the impact and return on investment of the Take Kare Safe Space (TKSS) program-a harm reduction program implemented to address alcohol-related violence and disorder in three locations in Sydney's night-time economy between 2014 and 2019. TKSS ambassadors provided support at static safe spaces and patrolled designated nightlife precincts to provide practical assistance to vulnerable and intoxicated people. Ambassadors recorded information relating to these interactions including 'client' age, gender, perceived level of intoxication, time and length of engagement with the program. Costs of program implementation and benefits of major incidents averted were obtained to allow calculation of return on investment. From December 2014 to April 2019, 66,455 people were supported by TKSS ambassadors. Most users were male (62%) and aged 18-25 years (66%). Of 3633 interventions by ambassadors, serious risk of harm was averted in 735 cases (20%). The program's return on investment is estimated at 2.67, suggesting that a $1 investment results in $2.67 in benefits. Safe Spaces are extensively utilized, particularly by young males with high levels of intoxication, and represent a positive return on investment. Despite the growth of such services, there remains a notable absence of rigorous, independent evaluation regarding the outcomes and/or social benefit of safe space programs. From a policy perspective, there is a need for more high-quality economic evaluations to better inform decisions about competing uses of limited resources.

This study determines an optimal strategy for scaling up ART in Vietnam by examining three initiation thresholds [350 cells/mm(3), 500 cells/mm(3), and treat all people living with HIV (PLHIV) regardless of CD4 cell counts] and treatment commencement rates among treatment-eligible PLHIV ranging from 5% to 100% within 12 months of diagnosis. Incremental cost-effectiveness ratios (ICERs) were calculated using a Markov model, based on data from a cohort of 3449 patients who initiated ART between January 1, 2005 and December 31, 2009 in 13 outpatient clinics across six provinces in Vietnam. Our analyses indicated that raising treatment eligibility criteria, in line with WHO guidelines (CD4 ≤500 cells/mm(3)) or removing CD4-based criteria would both be cost-effective in Vietnam. However, the cost-effective strategy from an economic viewpoint is first to increase coverage substantially among those with lowest CD4 levels, and only when coverage increases towards saturation should initiation criteria be lifted. Universal coverage under current guidelines would cost an additional $85 million and $96 million per year if the treatment threshold was 500 cells/mm(3). These scenarios would avert 15,000 and 22,000 HIV-related deaths in 2010-2019, with ICERs of $500-$660 per QALY gained. It is imperative to increase treatment coverage for newly diagnosed PLHIV in Vietnam according to the current guidelines prior to increasing the CD4 threshold for ART initiation.

OBJECTIVE: This study examines the proportions and causes of virological failure after one year of antiretroviral therapy (ART) among people living with HIV (PLHIV) in Vietnam. It also evaluates the positive predictive value (PPV) of immunological criteria to detect treatment failure. METHOD: A retrospective cohort of 3449 people with HIV who started ART between 1 January 2005 and 31 December 2009 in 13 outpatient clinics in Vietnam was studied. Multivariate logistic regression modeling was used to calculate crude and adjusted ORs and 95% CIs for associations between patient characteristics and virological failure. RESULTS: An estimated 6.5% (226/3449) of HIV patients in the participating clinics in Vietnam had confirmed virological failure one year after the start of ART. After adjusting for other factors, patients with a baseline CD4 count of 50-100 cells/mm(3) and 101-200 cells/mm(3) were statistically significantly less likely to have virological failure, compared to those with a baseline CD4 count lower than 50 cells/mm(3) (OR=0.61, 95% CI 0.23-0.89; and OR=0.43, 0.18-0.78, respectively). In contrast, patients with a history of injecting drug use were statistically significantly more likely to have viraemia than otherwise (OR=1.32, 1.16-1.67). The PPV of the WHO immunological criteria was 60.1% (57.1-69.3%). CONCLUSIONS: Routine viral load tests should be conducted early to detect virological failure and prevent unnecessary changes to second-line treatments. To improve treatment outcomes, timely ART initiation and adherence to treatment among those with history of injecting drug use should be promoted.

BACKGROUND: This study aims to describe the trends in and determinants of six month mortality and loss to follow up (LTFU) during 2005-2009 in 13 outpatient clinics in Vietnam. METHOD: Data were obtained from clinical records of 3,449 Vietnamese HIV/AIDS patients aged 18 years or older who initiated ART between 1 January 2005 and 31 December 2009. Mantel-Haenszel chi-square test, log rank test were conducted to examine the trends of baseline characteristics, six month mortality and LTFU. Cox proportional hazards regression models were performed to compute hazard ratio (HR) and 95% Confidence Interval (CI). RESULTS: Though there was a declining trend, the incidence of six month mortality and LTFU remained as high as 6% and 15%, respectively. Characteristics associated with six month mortality were gender (HR females versus males 0.54, 95%CI: 0.34-0.85), years of initiation (HR 2009 versus 2005 0.54, 95%CI: 0.41-0.80), low baseline CD4 (HR 350-500 cells/mm(3) versus <50 cells/mm(3) 0.26, 95%CI: 0.18-0.52), low baseline BMI (one unit increase: HR 0.96, 95%CI: 0.94-0.97), co-infection with TB (HR 1.61, 95%CI: 1.46-1.95), history of injecting drugs (HR 1.58, 95%CI: 1.31-1.78). Characteristics associated with LTFU were younger age (one year younger: HR 0.97, 95%CI: 0.95-0.98), males (HR females versus males 0.82, 95%CI: 0.63-0.95), and poor adherence (HR 0.55, 95%CI: 0.13-0.87). CONCLUSIONS: To reduce early mortality, special attention is required to ensure timely access to ART services, particularly for patients at higher risk. Patients at risk for LTFU after ART initiation should be targeted through enhancing treatment counselling and improving patient tracing system at ART clinics.

OBJECTIVES: This study explores patient characteristics that are significantly associated with very late combination antiretroviral therapy (cART) initiation (CD4 count ≤100 cells/mm³) and examines the association between patient characteristics and treatment outcomes, CD4 recovery, and mortality. DESIGN: Data were obtained from the clinical records of 2,198 HIV/AIDS patients in 13 outpatient clinics across 6 provinces in Vietnam. METHODS: Multivariate logistic regression and Cox proportional hazards regression were used to identify patient characteristics that are significantly associated with very late cART initiation and to measure relationships between patient characteristics and treatment outcomes. RESULTS: Very late cART initiation was significantly associated with being male compared with female (odds ratio [OR], 0.36; 95% CI, 0.23-0.58), becoming HIV infected through injecting drugs (OR, 2.13; 95% CI, 1.09-4.14), and having opportunistic infections at cART initiation (OR, 1.69; 95% CI, 1.02-2.86). Being male (female vs male: hazard ratio [HR], 0.45; 95% CI, 0.20-0.98), very late cART initiation (timely vs late: HR, 0.18; 95% CI, 0.04-0.72), low baseline body mass index (BMI) (HR, 0.95; 95% CI, 0.92-0.98), and later baseline WHO clinical stage (WHO clinical stage IV vs combined group of stage I and II: HR, 5.70; 95% CI, 3.90-7.80) were significantly associated with death, whereas being female compared with male (HR, 1.51; 95% CI, 1.14-1.99) and timely cART initiation (HR, 35.45; 95% CI, 13.67-91.91) were significant predictors of CD4 recovery. CONCLUSIONS: Timely testing of patients for HIV, increasing use of CD4 count testing services, and starting cART earlier are essential to reduce mortality and improve treatment outcomes.

In Vietnam, premature mortality due to AIDS-related conditions is commonly associated with late initiation to antiretroviral therapy (ART). This study explores reasons for late ART initiation among people living with HIV (PLHIV) from the perspectives of health care providers and PLHIV. The study was undertaken in six clinics from five provinces in Vietnam. Baseline CD4 counts were collected from patient records and grouped into three categories: very late initiators (≤100 cells/mm(3) CD4), late initiators (100-200 cells/mm(3)) and timely initiators (200-350 cells/mm(3)). Thirty in-depth interviews with patients who started ART and 15 focus group discussions with HIV service providers were conducted and thematic analysis of the content performed. Of 934 patients, 62% started ART very late and 11% initiated timely treatment. The proportion of patients for whom a CD4 count was obtained within six months of their HIV diagnosis ranged from 22% to 72%. The proportion of patients referred to ART clinics by voluntary testing and counselling centres ranged from 1% to 35%. Structural barriers to timely ART initiation were poor linkage between HIV testing and HIV care and treatment services, lack of patient confidentiality and a shortage of HIV/AIDS specialists. If Vietnam's treatment practice is to align with WHO recommendations then the connection between voluntary counselling and testing service and ART clinics must be improved. Expansion and decentralization of HIV/AIDS services to allow implementation at the community level increased task sharing between doctors and nurses to overcome limited human resources, and improved patient confidentiality are likely to increase timely access to HIV treatment services for more patients.

OBJECTIVE: Anomalous coronary vessels can result in sudden cardiac death. Coronary angiography is typically used to make the diagnosis; however, other modalities have been used, including transesophageal Doppler ultrasound, MRI, electron beam CT, and helical CT. We report two cases of evaluation of anomalous coronary vessels using multi-detector CT without cardiac gating. CONCLUSION: Our experience suggests that multi-detector CT with its rapid scanning time, superior spatial resolution, and wide availability could make it a viable tool in the evaluation of anomalous coronary anatomy in angiographically equivocal cases.
