Association of oral health status with the CD4+ cell count in children living with HIV in Phnom Penh, Cambodia

The association between oral and overall health, and particularly between dental and immune health, in children living with HIV remains unclear. This study examined the association between the decayed, missing and filled teeth (DMFT) score and CD4+ cell counts in 142 children living with HIV aged 8–15 years (male, 51%) from Phnom Penh, Cambodia. Other indicators of oral health (e.g., debris index, salivary flow, salivary pH and oral health-related quality of life) and overall health (e.g., nutritional status and quality of life) were also evaluated. DMFT scores were negatively associated with the CD4+ cell count in male children (β: −0.13, 95% confidence interval [CI]: −0.25, −0.02). In all children, positive associations were observed between salivary pH and CD4+ count (β: −0.645, 95% CI: 0.02, 1.25) and between salivary flow and height-for-age Z-score (β: 1.22, 95% CI: 0.50, 1.95). The debris index was negatively associated with the height-for-age Z-score (β: −2.04, 95% CI: −3.38, −0.71). In summary, oral health was associated with immune and nutritional status. Oral health policies for children living with HIV should be emphasised, and further studies should evaluate the mechanism underlying the relationship between oral and overall health.

"Who cares" is key: factors associated with oral health status in children living with HIV in Phnom Penh, Cambodia

This cross-sectional study aimed to identify social, clinical, and behavioral factors associated with the oral health status of children living with HIV in Phnom Penh, focusing particularly on the effect of primary caregiver type. Data were collected through separate interviews with children and caregivers. The decayed, missing, filled permanent teeth (DMFT) index and debris index scores were assessed for each child. Associations between oral health status and caregiver type as well as with other factors were examined using multiple linear regression. Of 142 total dyads (mean child and caregiver age, 12.3 (SD 1.8) and 44.8 (SD 10.6) years, respectively) 48.6% and 29.6% of caregivers were biological parents and institutional staff, respectively. Children with institutional staff as a primary caregiver had a lower DMFT score (2.81 vs. 5.50), higher rate of ever visiting a dentist (90.5% vs. 50.7%), and better oral health status than those cared for by biological parents. Higher DMFT score was negatively associated with institutional staff as primary caregiver (β: -1.642, 95% CI: -2.925, -0.360) and positively associated with longer antiretroviral therapy period (β: 0.223, 95% CI: 0.056, 0.390). Targeted oral health care programs are needed for children living with HIV whose biological parents are their primary caregivers.

The impact of completion thyroidectomy

INTRODUCTION

The oncological benefit of completion thyroidectomy (CT) following thyroid lobectomy (TL) is presumed to be similar to that of upfront total thyroidectomy(TT), from a patient's perspective the risk and inconvenience of further surgery adds significantly to the impact of the overall treatment. The aim of this study is to assess the impact of CT in terms of the duration of admission and associated complications.

METHODS

A study of consecutive patients with DTC identified from prospective MDT records of South-East Scotland from 2009 to 2015. Surgical data was extracted from electronic medical record.

RESULTS

Of 361 patients diagnosed with DTC, 161 (45%) had CT. The median postoperative stay was 1 day (range 1-5days). In total 22 patients (14%)suffered complications. Four patients (3%) developed postoperative haematoma. Two (1%) had an identified permanent nerve palsy on the completion side. 13 patients (8%) remained on calcium supplementation for more than 6 months postoperatively and three patients (2%) developed wound complications.

CONCLUSIONS

Our study confirms that CT is regularly performed (45%). Recent changes in international guidelines recognize increasing number of patients as eligible for a conservative approach but recommend CT based on whether upfront TT would have been recommended if the TL pathology were known from the outset. Such an approach fails to consider the additional risk and inconvenience of CT on the overall patient experience. Due to a relatively high rate of complications, only those patients who are most likely to benefit from further surgery to facilitate adjuvant radioactive iodine should be offered additional surgery.

Characteristics of adolescents living with HIV receiving care and treatment services in antiretroviral therapy clinics in Cambodia: descriptive findings from a cross-sectional study

Background

Adolescents living with HIV experience worse HIV care outcomes compared to adults, especially during transition from pediatric to adult care. However, data regarding adolescents are limited. This paper describes and compares characteristics of male and female adolescents living with HIV preparing for transition from pediatric to adult care in Cambodia.

Methods

This cross-sectional study was conducted in August 2016 among 328 adolescents aged 15–17, randomly selected from 11 antiretroviral therapy (ART) clinics. Data were collected using a structured questionnaire, and descriptive analyses were conducted to compare characteristics of male and female adolescents.

Results

Of total, 55.2% were male, and 40.8% were living with parents. Majority (82.6%) got HIV infection from their mothers. Overall, adolescents had received ART for an average of 8.4 years, and HIV care for 9.5 years. Additionally, 82.4% were on first line ART regimen. Mean CD4 count from the most recent test was 672 cells/mm³, and viral load was 7686 copies/mL. Overall, 95.6% were adherent to ART on Visual Analogue Scale. About half (50.7%) had never disclosed their HIV status to anyone, while the remaining had disclosed it to their siblings (24.2%), friends (13.0%), schoolteachers (2.4%), or other (5.8%). A fifth reported having had boy or girlfriends, but few (2.1%) had ever had sexual intercourse. Females were more likely to have been engaged in sexual intercourse, and none reported having used a condom in their last intercourse. Few participants reported having ever used tobacco (1.8%), or any kind of illicit drugs (0.9%), but almost a fifth (20.7%) had a history of alcohol use. The majority (82.1%) were aware that they were receiving ART. HIV-related knowledge was suboptimal among the sample.

Conclusions

This study provides a snapshot of immunological, virological, adherence, and disclosure outcomes that should be tracked during and following healthcare transition to evaluate the effectiveness of the transition program. Findings showed high ART adherence, low likelihood of disclosure outside of family circles, sub-optimal condom use, and poor knowledge of HIV. To provide individualized support for healthcare transition, pediatric and adult clinics need to ensure that these characteristics are taken into account.

Social and behavioural factors associated with depressive symptoms among university students in Cambodia: a cross-sectional study

OBJECTIVE

To explore social and behavioural factors associated with depressive symptoms among university students in Cambodia.

DESIGN

Cross-sectional study.

SETTINGS

Two public universities-one in the capital city of Phnom Penh and another in Battambang provincial town.

PARTICIPANTS

This study included 1359 students randomly selected from all departments in the two universities using a multistage cluster sampling method for a self-administered questionnaire survey in 2015.

PRIMARY OUTCOME MEASURE

Depressive symptoms measured by using the Center for Epidemiologic Studies Depression scale. All measures in the study were self-reported.

RESULTS

The proportion of students with depressive symptoms and severe depressive symptoms were 50.6% and 19.6%, respectively. After adjustment in multivariate logistic regression analysis, depressive symptoms remained significantly associated with poor academic performance (adjusted OR (AOR)=7.31, 95% CI 2.24 to 23.86), higher consumption of unhealthy food (AOR=1.72, 95% CI 1.08 to 2.76), a negative self-perception about body shape (AOR=0.54, 95% CI 0.29 to 0.99) and general health status (AOR=2.99, 95% CI 1.28 to 7.00), and limited physical activeness (AOR=0.30, 95% CI 0.16 to 0.58). Depressive symptoms also remained significantly associated with adverse childhood experiences including physical violence (AOR=1.39, 95% CI 1.04 to 1.86), psychological abuse (AOR=1.82, 95% CI 1.37 to 2.42) and lack of general and medical care (AOR=0.51, 95% CI 0.30 to 0.86) by family during childhood.

CONCLUSIONS

The key factors associated with depressive symptoms were family related and individual behaviours and attitudes. Thus, efforts should be invested in comprehensive screening and intervention programmes to diagnose those vulnerable students early, offer immediate treatment and cater appropriate support.

Sexual behaviors, HIV knowledge, HIV testing attitudes and recent HIV testing among female entertainment workers in Cambodia: A cross-sectional study

Background

In Cambodian context, female entertainment workers (FEWs) are young women working at establishments such as karaoke bars, restaurants, beer gardens or massage parlors. FEWs may sell sex to male patrons and are considered a high-risk group for HIV. This study aimed to identify factors associated with recent HIV testing among FEWs in Cambodia to inform future prevention activities.

Methods

Data were collected in 2014 as part of the evaluation of a larger HIV prevention project. A two-stage cluster sampling method was used to select participants from Phnom Penh and Siem Reap for face-to-face interviews using a structured questionnaire. A logistic regression model was constructed to identify independent factors associated with recent HIV testing.

Results

Data were collected from 667 FEWs with a mean age of 25.6 (SD = 5.5). Of total, 81.7% reported ever having had an HIV test, and 52.8% had at least one test in the past six months. After adjustment for other covariates, factors independently associated with recent HIV testing included living in Phnom Penh (AOR = 2.17, 95% CI = 1.43–3.28), having received HIV education in the past six months (AOR = 3.48, 95% CI = 2.35–5.15), disagreeing with a statement that ‘I would rather not know if I have HIV’ (AOR = 2.15, 95% CI = 1.41–3.30), agreeing with a statement that ‘getting tested for HIV helps people feel better’ (AOR = 0.32, 95% CI = 0.13–0.81) and not using a condom in the last sexual intercourse with a non-commercial partner (AOR = 0.48, 95% CI = 0.26–0.88).

Conclusions

FEWs with greater knowledge and positive attitudes towards HIV testing got tested for HIV more frequently than those with lesser knowledge and less positive attitudes. These findings suggest that future interventions should focus on disseminating tailored health messages around testing practices as well as specific topics such as condom use with non-commercial partners.

Prevention of chemotherapy toxicity by agents that neutralize or degrade cell-free chromatin

Background

Toxicity associated with chemotherapy is a major therapeutic challenge and is caused by chemotherapy-induced DNA damage and inflammation. We have recently reported that cell-free chromatin (cfCh) fragments released from dying cells can readily enter into healthy cells of the body to integrate into their genomes and induce DNA double-strand breaks, apoptosis and inflammation in them. We hypothesized that much of the toxicity of chemotherapy might be due to release of large quantities of cfCh from dying cells that could trigger an exaggerated DNA damage, apoptotic and inflammatory response in healthy cells over and above that caused by the drugs themselves.

Methods

We tested this hypothesis by administering cfCh neutralizing/degrading agents namely, anti-histone antibody complexed nanoparticles, DNase I and a novel DNA degrading agent-Resveratrol-Cu concurrently with five different chemotherapeutic agents to examine if chemotherapy-induced toxicity could be minimized.

Results

We observed (i) significant reduction in chemotherapy-induced surge of cfCh in blood; (ii) significant reduction in chemotherapy-induced surge of inflammatory cytokines CRP, IL-6, IFNγ and TNFα in blood; (iii) abolition of chemotherapy-induced tissue DNA damage (γH2AX), apoptosis (active caspase-3) and inflammation (NFκB and IL-6) in multiple organs and peripheral blood mononuclear cells; (iv) prevention of prolonged neutropenia following a single injection of adriamycin and (v) significant reduction in death following a lethal dose of adriamycin.

Conclusion

Our results suggest that toxicity of chemotherapy is caused to a large extent by cfCh released from dying cells and can be prevented by concurrent treatment with cfCh neutralizing/degrading agents.

Patterns of HIV testing, drug use, and sexual behaviors in people who use drugs: findings from a community-based outreach program in Phnom Penh, Cambodia

Background

People who use drugs are an important priority for HIV programs. However, data related to their utilization of HIV services are limited. This paper reports patterns of HIV testing, drug use, and risk and service perception among people who use drugs. Study participants were receiving HIV and harm reduction services from a community-based program in Phnom Penh, comprised of itinerant peer-led outreach and static drop-in centers.

Methods

This was a mixed-methods study conducted in 2014, comprising of a quantitative survey using a structured questionnaire, followed by two focus group discussions among a sub-sample of survey participants. Participants were recruited from hotspots in five HIV high-burden communes using a two-stage cluster sampling method. Quantitative descriptive analyses and qualitative thematic analyses were performed.

Results

This study included 151 people who use drugs with a mean age of 31.2 (SD = 6.5) years; 77.5% were male and 39.1% were married. The most common drugs used were methamphetamines (72.8%) and heroin (39.7%), and 38.0% injected drugs in the past 3 months. Overall, 83.3% had been tested for HIV in the past 6 months, of whom 62.5% had been tested by peers through community-based outreach. However, there were ongoing HIV risks: 37.3% were engaging in sex on drugs, only 35.6% used a condom at last sexual intercourse, and 10.8% had had a sexually transmitted infection in the last 6 months. Among people who reported injecting drugs in the past 3 months, 27.5% reported re-using needles/syringes. Almost half (46.5%) perceived themselves as being at lower risk of HIV compared to the general population. Qualitative results contextualized the findings of low perception of HIV risks and suggested that although services were often unavailable on weekends, at night, or during national holidays, peer-led community-based outreach was highly accepted.

Conclusions

A peer-led community-based approach was effective in reaching people who use drugs with HIV and harm reduction interventions. To mitigate ongoing HIV risks, expanding access to combination prevention interventions and implementing strategies to enable people who use drugs to objectively assess their HIV risks are required. Additionally, community-based programs should collect data along the care continuum, to enable decentralized tracking of progress towards 90–90–90 goals at local levels.

High prevalence of non-communicable diseases and associated risk factors amongst adults living with HIV in Cambodia

Background

With rapid expansion of antiretroviral therapy for HIV, there are rising life expectancies among people living with HIV. As a result, co-morbidity from non-communicable diseases in those living and aging with HIV is increasingly being reported. Published data on this issue have been limited in Cambodia. The aim of this study was to determine the prevalence of diabetes mellitus, hypertension and hypercholesterolemia and associated risk factors in adults living with HIV in Cambodia.

Methods

This cross-sectional study was conducted in five provinces of Cambodia from May-June 2015. Information was obtained on socio-demographic and clinical characteristics through face-to-face interviews using a structured questionnaire, and anthropometric and biochemical measurements were performed. Diabetes mellitus was diagnosed with fasting blood glucose ≥126 mg/dl, hypertension with systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥ 90 mmHg and hypercholesterolemia with fasting blood cholesterol ≥190 mg/dl. Multivariable logistic regression analyses were used to explore risk factors.

Results

The study sample included 510 adults living with HIV; 67% were female, with a mean age of 45 (standard deviation = 8) years. Of these, 8.8% had diabetes mellitus, 15.1% had hypertension and 34.7% had hypercholesterolemia. Of the total participants with non-communicable diseases (n = 244), 47.8% had one or more diseases, and 75% were not aware of their diseases prior to the study: new disease was diagnosed in 90% of diabetes mellitus, 44% of hypertension and 90% of hypercholesterolemia. Single disease occurred in 81%, dual disease in 17% and triple disease in 2%. In adjusted analyses, those consuming 1 serving of fruit compare to 2 servings as significantly with diabetes mellitus, those eating 1 serving of fruit compare to 2 servings and using lard for cooking were significantly associated with hypertension, and those being unemployed, having monthly income less than 100 USD and being underweighted were significantly associated with hypercholesterolemia.

Conclusions

The prevalence of diabetes mellitus, hypertension and hypercholesterolemia in adults living with HIV in this study was considerably high, with most of these diseases newly identified through active screening in the survey. These findings strongly suggest that screening of non-communicable diseases should be integrated into routine HIV care in Cambodia.

Non-communicable diseases and related risk behaviors among men and women living with HIV in Cambodia: findings from a cross-sectional study

BACKGROUND

There is a growing concern for an increasing burden of non-communicable diseases (NCDs) in people living with HIV. This concern is evident especially in developing countries where dietary and lifestyle risk factors associated with NCDs are becoming more prominent. This study explored the prevalence of diabetes mellitus, hypertension, and hyperlipidemia and related risk factors in men and women living with HIV in Cambodia.

METHODS

This cross-sectional study was conducted among 510 adult people living with HIV randomly selected from one city and four provinces in Cambodia. A structured questionnaire was used to collect data on socio-demographic characteristics, health behaviors, medical history, and antiretroviral therapy (ART). Anthropometric and biological measurements were performed. Descriptive statistics were used to calculate proportions and means of the measured variables. An independent Student's t-test was used for continuous variables. Chi square test or Fisher's exact test was used for categorical variables to explore gender differences.

RESULTS

Prevalence of diabetes mellitus, hypertension, and hyperlipidemia was 9.4, 15.1, and 33.7%, respectively. The prevalence of hyperlipidemia was significantly higher among men compared to women. Mean systolic and diastolic blood pressures were also significantly higher among men. Regarding risk factors, 17.3% of participants were overweight, and 4.1% were obese. Tobacco and alcohol use was common, particularly among men. Fruit and vegetable consumption was considerably low among both men and women. Physical activity levels were also low. About 40% of participants reported having a job that involved mostly sitting or standing; 46.3% reported engaging in moderate activities; and 11.8% reported engaging in vigorous activities during leisure time. A significantly higher proportion of men compared to women engaged in vigorous activities both at work and during leisure time.

CONCLUSIONS

The prevalence of diabetes mellitus, hypertension, and hyperlipidemia among men and women living with HIV in Cambodia is considerably high. Related risk factors were also common. Given the comorbidity of NCDs and HIV, policy and programmatic interventions are required, including integration of NCD screening into HIV programs. Distinctions in the levels of diseases and in health behaviors between men and women suggest that interventions need to be tailor-made and gender-specific, targeting their respective diseases and behaviors.

How understanding and application of drug-related legal instruments affects harm reduction interventions in Cambodia: a qualitative study

BACKGROUND

Harm reduction interventions in Cambodia face numerous obstacles because of conflicting understanding and interests and inconsistencies in the implementation by law enforcement officials. This study aims to examine how understanding and application of Drug Control Law (DCL) and Village/Commune Safety Policy (VCSP) affects harm reduction interventions in Cambodia from the standpoints of law enforcement officials, people who inject drugs and people who use drugs (PWID/PWUD), as well as other key stakeholders.

METHODS

This qualitative study was conducted in the capital city of Phnom Penh in 2015. We held five focus group discussions (FGDs) with groups of PWID/PWUD, police officers, Sangkat/commune officers, and local non-governmental organization (NGO) field staff. We also conducted ten key informant interviews (KIIs) with representatives from government agencies, donor agencies, and NGOs. FGDs and KIIs with Cambodian participants were transcribed in Khmer and translated into English. KIIs with foreign participants were transcribed in English. Transcripts were read and re-read to identify emerging themes, which were reviewed and refined to develop common and divergent patterns.

RESULTS

There was a huge gap between what the DCL and VCSP say and how law enforcement officers and PWID/PWUD understood them. The gap was also evident in how law enforcement officers implemented the DCL and VCSP. Harm reduction services, including health- and non-health-related interventions, were limited and challenged by unsupportive attitudes, misinterpretation of the DCL and VCSP, and the lack of full engagement with NGOs in the development of these instruments. The needs of PWID/PWUD in accessing health care services were not met due to misconduct of authorities while practicing the DCL and VCSP. Further, the misconduct and enforcement of the law and policy lead to increased social discrimination and physical abuses against PWID/PWUD.

CONCLUSIONS

There is a lack of common understanding of the drug-related law and policy and their implications to harm reduction services among both law enforcement officers and PWID/PWUD. Thus, there is a need to mainstream and simplify the law and policy for better comprehension among these actors. To improve the quality and coverage of harm reduction interventions, the gap of understanding and enforcement of laws and policies should be narrowed, and coordination between the government and NGOs and other key stakeholders should be strengthened.

HIV prevalence, risky behaviors, and discrimination experiences among transgender women in Cambodia: descriptive findings from a national integrated biological and behavioral survey

BACKGROUND

Transgender people are disproportionately affected by HIV. Despite their high vulnerability to HIV, lack of adequate epidemiological and surveillance data related to this population in many countries prevents provision of appropriate services. This paper summarizes descriptive findings from a national integrated biological and behavioral survey and discusses policy implications of the findings on HIV prevention among transgender women in Cambodia.

METHODS

This cross-sectional study was conducted between December 2015 and February 2016. Participants were recruited from 20 sites in the capital city and 12 provinces of Cambodia using Respondent Driven Sampling (RDS) method. Behavioral data were collected through structured questionnaire interviews, and rapid finger-prick HIV testing was performed. Descriptive data analyses were conducted using STATA.

RESULTS

This study included 1,375 transgender women with a mean age of 25.9 years (SD = 7.1). The overall prevalence of HIV was 5.9%. The prevalence of HIV was significantly higher among urban participants compared to their rural counterparts (6.5 vs. 2.6%, p = 0.02). Almost one in five (19.6%) had never been tested for HIV prior to the study. Overall, 45.0% reported ever using gender affirming hormones. More than one-third (39.1%) reported not using condoms in their last sex, 29.8% had engaged in sex in exchange for money/gifts, and 14.0% reported that they had experienced at least one symptom of sexually transmitted infections (STI) in the past year. About one in ten (10.1%) reported having used some form of amphetamine-type stimulant drugs, while 6.5% reported having sex during or after using illicit drugs. A significant number of participants experienced sexual abuse (39.2%), losing a job (24.3%), or physical abuse (23.6%) because of their transgender identity. In addition, 82.9 and 88.9% would be willing to use the HIV self-test and pre-exposure prophylaxis (PrEP), respectively, if they become available.

CONCLUSIONS

The high prevalence of HIV, STI, and related risk behaviors among transgender women in Cambodia is of great concern, suggesting an urgent need to further expand tailored prevention interventions for this key population focusing on individual, social, and structural drivers of HIV. HIV self-test and PrEP should be explored as a priority.

Sex with sweethearts: Exploring factors associated with inconsistent condom use among unmarried female entertainment workers in Cambodia

BACKGROUND

Despite the success in promoting condom use in commercial relationships, condom use with regular, noncommercial partners remains low among key populations in Cambodia. This study explores factors associated inconsistent condom use with sweethearts among unmarried sexually active female entertainment workers (FEWs).

METHODS

In 2014, the probability proportional to size sampling method was used to randomly select 204 FEWs from entertainment venues in Phnom Penh and Siem Reap for face-to-face interviews. Multivariate logistic regression analysis was conducted to examine independent determinants of inconsistent condom use.

RESULTS

Of total, 31.4% of the respondents reported consistent condom use with sweethearts in the past three months. After adjustment, respondents who reported inconsistent condom use with sweethearts remained significantly less likely to report having received any form of sexual and reproductive health education (AOR = 0.49, 95% CI = 0.22-0.99), but more likely to report having been tested for HIV in the past six months (AOR = 2.19, 95% CI = 1.03-4.65). They were significantly more likely to report having used higher amount of alcohol in the past three months (AOR = 1.29, 95% CI = 1.01-1.99) and currently using a contraceptive method other than condoms such as pills (AOR = 4.46, 95% CI = 1.34-10.52) or other methods (AOR = 9.75, 95% CI = 2.07-9.86).

CONCLUSIONS

The rate of consistent condom use in romantic relationships among unmarried FEWs in this study is considerably low. The importance of consistent condom use with regular, non-commercial partners should be emphasized in the education sessions and materials, particularly for FEWs who use non-barrier contraceptive methods.

Mobile phone use among female entertainment workers in Cambodia: an observation study

BACKGROUND

Text or voice messages containing health behavior change content may be an inexpensive, discreet, sustainable and scalable way to reach populations at high risk for HIV. In Cambodia, one of the important high-risk populations is female entertainment workers (FEWs). This ethnographic study aims to explore typical phone use, examining patterns and behaviors that may influence the design of future mHealth interventions.

METHODS

The study consisted of one 8-hour non-participant observation session for 15 randomly sampled FEWs. Observations focused on capturing normal daily use of mobile devices. Observation checklists were populated by observers during the observations and a post-observation survey was conducted. Findings were discussed with Cambodian HIV outreach workers and HIV research fellows and their interpretations are summarized below.

RESULTS

In this ethnographic study, all 15 participants made calls, checked the time and received research-related texts. More than half (n=8) of the participants engaged in texting to a non-research recipient. About half (n=7) went on Facebook (FB) and some (n=5) listened to music and looked at their FB newsfeed. Fewer played a mobile game, posted a photo to FB, went on YouTube, used FB chat/messenger, watched a video on FB, played a game on FB, used FB call/voice chat, looked at their phone's background or used the LINE app. Fewer still shared their phones, left them unattended, added airtime or changed their SIM cards. When participants received a research text message, most did not share the text message with anyone, did not ask for help deciphering the message and did not receive help composing a response. Notable themes from observer notes, HIV outreach workers and researchers include reasons why phone calls were the most frequent mode of communication, examples of how cell phone company text messages are used as a form of behavior change, literacy as a persistent barrier for some FEWs, and FEWs' high interest in receiving health-related messages and less concern about privacy and phone-sharing issues than expected.

CONCLUSIONS

This study suggests texting is a part of normal phone use although not as frequently used as voice calls or Facebook. Despite the less frequent use, FEWs were able to send and receive messages, were interested in health messages and were not overly concerned about privacy issues. Texting and voice messaging may be useful tools for health behavior change within the FEW population in Cambodia.

Acceptability Study on HIV Self-Testing among Transgender Women, Men who Have Sex with Men, and Female Entertainment Workers in Cambodia: A Qualitative Analysis

BACKGROUND

In Cambodia, HIV prevalence is high while HIV testing rates remain low among transgender women (TG women), men who have sex with men (MSM), and female entertainment workers (FEW). Introducing self-testing for HIV to these key populations (KPs) could potentially overcome the under-diagnosis of HIV and significantly increase testing rates and receipt of the results, and thus could decrease transmission. Therefore, this study aimed to determine the acceptability of HIV self-testing (HIVST) among these three categories of KPs.

METHODS

This study was conducted through focus group discussions (FGDs) with TG women, MSM, and FEW in Phnom Penh city, Kampong Cham, Battambang, and Siem Reap provinces of Cambodia. Convenience sampling was used to recruit the participants. Two FGDs (six participants in each FGD) were conducted in each target group in each study site, totaling 24 FGDs (144 participants). Thematic analysis was performed to identify common or divergent patterns across the target groups.

RESULTS

Almost all participants among the three groups (TG women, MSM, and FEW) had not heard about HIVST, but all of them expressed willingness to try it. They perceived HIVST as confidential, convenient, time-saving, and high-tech. Barriers to obtaining HIVST included cost, access, administration technique, embarrassment, and fear of pain. The majority preferred counseling before and after testing.

CONCLUSIONS

Participants showed high willingness to use and acceptability of HIVST due to its confidentiality/privacy and convenience even if it is not linked to a confirmatory test or care and treatment. Notwithstanding, to increase HIVST, the target groups would need affordable self-test kits, education about how to perform HIVST and read results, assurance about accuracy and reliability of HIVST, and provision of post-test counseling and facilitation of linkage to care and treatment.

Improving prevention and care for HIV and sexually transmitted infections among men who have sex with men in Cambodia: the sustainable action against HIV and AIDS in communities (SAHACOM)

BACKGROUND

The prevalence of HIV and sexually transmitted infections (STIs) among key populations in Cambodia continues to rise. To address this issue, KHANA, the largest national HIV organization in the country developed and implemented the Sustainable Action against HIV and AIDS in Communities (SAHACOM) project. This study aims to determine the impacts of the SAHACOM on sexual behaviors and the uptake of HIV/STI services among men who have sex with men (MSM) in Cambodia.

METHODS

We compared outcome indicators at midterm (n = 352) and endline (n = 394). Surveys were conducted in 2012 and 2014 in Battambang and Siem Reap provinces. A two-stage cluster sampling method was employed to select the study sample for structured interviews.

RESULTS

The midterm and endline samples were similar. The average number of sexual partners in the past three months decreased significantly from 6.2 to 4.0 (p = 0.03). The proportion of MSM who reported paying for sex with men in the past three months also decreased significantly from 19.0 % to 9.7 % (OR = 2.0, 95 % CI = 1.3-3.0). No significant change was found in condom and lubricant use in all types of relationships. Regarding STIs, 28.1 % of MSM at midterm reported having at least one STI symptom in the past three months compared to 6.1 % at endline (OR = 4.6, 95 % CI = 2.9-7.4); out of them, 14.1 % of MSM at midterm sought treatment compared to 20.7 % at endline (OR = 2.6, 95 % CI = 1.1-6.9). The proportion of MSM who reported using illicit drugs in the past three months also decreased significantly from 12.2 % to 5.1 % (OR = 2.4, 95 % CI = 1.4-4.2). However, the proportion of MSM who reported having been tested for HIV in the past six months decreased significantly from 94.1 % to 77.1 % (OR = 2.9, 95 % CI = 1.8-3.6).

CONCLUSIONS

Findings from this study indicate that the SAHACOM was effective in improving sexual behaviors and related health outcomes among MSM under the project. However, it could not increase condom use and HIV testing rates among this key population. Tailored intervention programs are needed to improve condom use and HIV testing among MSM in Cambodia.

Prevalence and correlates of psychological distress among drug users in Phnom Penh, Cambodia

BACKGROUND

Compared to the general population, drug users are at increased risk of both poor mental health and HIV infection. The aim of this study was to determine the prevalence and correlates of high psychological distress among drug users in Cambodia.

METHODS

In April 2014, a two-stage cluster sampling method was used to randomly select 169 drug users from hotspots in Phnom Penh. Psychological distress was measured using General Health Questionnaire (GHQ-12). Bivariate and multivariable analyses were conducted to identify factors associated with levels of psychological distress among this population.

RESULTS

Our study found high prevalence of attempted suicide (15.3%), drug related arrests (46.2%), and incarceration (31.4%). Of the 169 participants, 42.0% were found to have high levels of psychological distress, indicating poor mental health. After adjustment, high levels of psychological distress were independently associated with suicidal ideation (p<0.001), higher frequency of drug use (p=0.02), sharing of needles or syringes (p=0.005), and having been sent to a rehabilitation centre (p=0.02). In addition, participants who perceived their overall health as being poor or very poor were more likely to have high levels of psychological distress (p=0.002).

CONCLUSION

Integration of mental health within HIV and needle and syringe exchange programmes is required to address psychological distress among drug users in Cambodia. Health system interventions, such as screening, referral, and training of health providers, need to be strengthened. In addition, interventions addressing social determinants of mental health and mitigation of frequent arrests and improving conditions in rehabilitation centres are required.

Are Text Messages a Feasible and Acceptable Way to Reach Female Entertainment Workers in Cambodia with Health Messages? A Cross-Sectional Phone Survey

Background

Despite great achievements in reducing the prevalence of HIV, eliminating new HIV infections remains a challenge in Cambodia. Entertainment venues such as restaurants, karaoke bars, beer gardens, cafes, pubs, and massage parlors are now considered important venues for HIV prevention efforts and other health outreach interventions.

Objective

The purpose of this study was to explore phone use and texting practices of female entertainment workers (FEWs) in order to determine if text messaging is a feasible and acceptable way to link FEWs to health services.

Methods

This cross-sectional phone survey was conducted in May 2015 with 97 FEWs aged 18–35 years and currently working at an entertainment venue in Phnom Penh.

Results

Of the 96 respondents, 51% reported sending text messages daily; of them, 47% used Khmer script and 45% used Romanized Khmer. Younger FEWs were more likely to report daily texting (P<.001). Most FEWs (98%) in this study reported feeling comfortable receiving private health messages despite the fact that 39% were sharing their phone with others. Younger FEWs were less likely to share their phone with others (P=.02). Of all of the FEWs, 47% reported owning a smartphone, and younger women were more likely to own a smartphone than were older women (P=.08).

Conclusions

The findings from this study support the development of mHealth interventions targeting high-risk groups in urban areas of Cambodia. Our data suggest that mHealth interventions using texting may be a feasible way of reaching FEWs in Phnom Penh.

Mental health among men who have sex with men in Cambodia: Implications for integration of mental health services within HIV programmes

Background

Poor mental health contributes to poor HIV prevention, treatment and care outcomes. This paper documents factors associated with psychological distress among men who have sex with men (MSM) in Cambodia and discusses potential ways in which routine mental health management could be integrated into HIV services.

Methods

A cross-sectional study was conducted in 2014 among 394 MSM randomly selected from two provinces using a two-stage cluster sampling method. A structured questionnaire was used to assess psychological distress, sexual behaviors, substance use, adverse childhood experiences and family dysfunction. Multivariate logistic regression analysis was performed to explore factors associated with levels of psychological distress.

Results

In total, 10.7 % of the respondents reported having suicidal thoughts and 6.6 % reported having attempted to commit suicide in the past three months, while 38.8 % had a higher level of psychological distress (GHQ-12 > 3), which indicates poor mental health. Higher levels of psychological distress were independently associated with older age (AOR = 1.09, 95 % CI 1.03–1.14), alcohol use (AOR = 3.3, 95 % CI 1.36–7.83), illicit drug use (AOR = 3.53, 95 % CI 1.12–11.18), poor self-reported quality of life (AOR = 7.45, 95 % CI 1.79–3.04), and reduced condom use at last sex (AOR = 0.40, 95 % CI 0.21–0.73). MSM with higher levels of psychological distress were significantly more likely to report that a family member said hurtful things to them (AOR = 1.80, 95 % CI 1.10–2.97), a parent or guardian had been physically abused (AOR = 3.51, 95 % CI 1.86–6.62), and a family member had been mentally ill (AOR = 4.01, 95 % CI 2.06–7.81) when they were growing up.

Conclusions

In order to mitigate psychological distress among MSM in Cambodia, integration of mental health interventions within HIV programmes should be strengthened. To achieve optimal impact, these interventions should also address alcohol and other substance use, and low condom use among distressed MSM. In addition, training of clinical and non-clinical HIV service providers to screen for mental health symptoms, and subsequent provision of peer-based outreach and social support for MSM identified with psychological distress is required.

HIV risk and psychological distress among female entertainment workers in Cambodia: a cross-sectional study

Background

In Cambodia, there has been an increase in entertainment work as a result of the breakdown of the traditional brothel-based sex industry, presenting new challenges to addressing the health issues and needs of people working in the entertainment industry. This study aims to identify factors associated with psychological distress among female entertainment workers (FEWs) in Cambodia.

Methods

A two-stage cluster sampling method was used to randomly select 657 FEWs from entertainment establishments in Phnom Penh and Siem Reap in April and May 2014 for interviews using a structured questionnaire. Psychological distress was measured using the General Health Questionnaire (GHQ-12), and multivariate logistic regression analysis was conducted.

Results

Almost half of FEWs (43.2 %) had a higher level of psychological distress (GHQ-12 > 3), while 19.5 % reported having suicidal thoughts, and 7.3 % reported having attempted to commit suicide in the past 3 months. Controlling for confounding factors, women with a higher level of psychological distress were significantly more likely to rate their overall health (AOR = 1.88, 95 % CI 1.20 to 2.94) and quality of life (AOR = 2.39, 95 % CI 1.47 to 3.87) as poor. They were also significantly more likely to have suicidal ideation (AOR = 2.41, 95 % CI 1.45 to 3.76), rate their HIV risk as higher than the general population (AOR = 0.48, 95 % CI 0.31 to 0.74), have been forced to drink at work (AOR = 1.77, 95 % CI 1.19 to 2.62), have had clients requesting not to use a condom (AOR = 3.48, 95 % CI 1.14 to 10.62), be not able to find condoms when they needed it (AOR = 0.64, 95 % CI 0.45 to 0.93), have had a family member who said hurtful things to them during childhood (AOR = 1.84, 95 % CI 1.24 to 2.75), and have had a parent or guardian who had been physically abused (AOR = 1.93, 95 % CI 1.34 to 2.82).

Conclusions

FEWs in Cambodia experience high levels of psychological distress, which likely stems from both past negative experiences and current working conditions. For women that are experiencing psychological distress, intervention programs aimed at improving mental health should specifically address substance use, condom availability and negotiation skills, and suicide risk.

Factors Associated with Inconsistent Condom Use among Men Who Have Sex with Men in Cambodia

Background

Compared to the general population, men who have sex with men (MSM) are at greater risk for HIV and less understood due to their more hidden and stigmatized nature. Moreover, the discrepancy in findings in the literature merits further investigations in MSM populations from different cultures and settings. We therefore conducted this study to explore factors associated with inconsistent condom use among high-risk MSM in Cambodia.

Methods

This cross-sectional study was conducted in 2014 among 367 MSM randomly selected from Battembang and Siem Reap using a two-stage cluster sampling method. A structured questionnaire was used for face-to-face interviews to collect information on characteristics of respondents, HIV testing history, self-perception of HIV risk, substance use, sexual behaviors, mental disorders, and HIV knowledge. Multivariable logistic regression analysis was performed to identify factors independently associated with inconsistent condom use.

Results

On average, 62.3% of respondents reported that they always used condoms over the past three months. The rates varied with types of sexual partners; the proportion of respondents who reported always using condoms was 55.1%, 64.2%, 75.9%, 73.0%, 78.1%, and 70.3%, for sexual partners who were girlfriends, boyfriends, female sex workers, male sex workers, female clients, or male clients, respectively. After adjustment, inconsistent condom use was significantly associated with age of ≥25 (AOR = 1.77, 95% CI = 1.09–2.86), self-rated quality of life as good or very good (AOR = 4.37, 95% CI = 1.79–5.67), self-perception of higher HIV risk compared to the general population (AOR = 2.37, 95% CI = 1.35–4.17), illicit drug use in the past three months (AOR = 5.76, 95% CI = 1.65–10.09), and reported consistent lubricant use when selling anal sex to men in the past three months (AOR = 2.85, 95% CI = 1.07–8.12).

Conclusions

We found risky sexual behaviors to be considerably high among MSM in this study, especially among those who used illicit drugs or were older than 25. HIV education and social marketing should be expanded and specifically designed for MSM to better educate on the increased risk of HIV with unprotected anal sex and illicit drug use as risk factors, and the importance of the use of both condoms and lubricant during anal intercourse.

Factors associated with recent HIV testing among high-risk men who have sex with men: a cross-sectional study in Cambodia

Background

Despite remarkable success in the fight against HIV, HIV prevalence in many countries remains high among key populations including men who have sex with men (MSM), and HIV testing rates is relatively low among this hard-to-reach population. This cross-sectional study explores factors associated with recent HIV testing among MSM in Cambodia.

Methods

This study was conducted in 2014 and included 384 MSM randomly selected from two provinces of Battembang and Siem Reap, using a two-stage cluster sampling method. A structured questionnaire was used for face-to-face interviews to collect data on socio-demographic characteristics, HIV testing history, sexual behaviors, HIV testing attitudes, and HIV knowledge. Multivariate logistic regression analysis was performed to identify factors independently associated with recent HIV testing.

Results

Mean age of the participants was 23.4 (SD = 5.2). Of total, 83.6 % had been tested for HIV at least once in their lifetime, and 65.1 % had been tested for HIV in the past six months. After controlling for other covariates, MSM who had been tested for HIV in the past six months were significantly more likely to regard themselves as female (AOR = 2.29, 95 % CI = 1.06-5.37), have received some form of HIV education in the past six months (AOR = 3.97, 95 % CI = 1.91-8.26), perceive that they were at higher HIV risk compared to the general population (AOR = 2.48, 95 % CI = 1.14-4.86), have been diagnosed with an STI in the past six months (AOR = 3.19, 95 % CI = 1.02-9.24), report using a condom at last sexual intercourse with a man or woman (AOR = 2.24, 95 % CI = 1.06-3.13), and report using a condom at last sexual intercourse with a boyfriend (AOR = 2.17, 95 % CI = 1.04-5.31).

Conclusions

This study highlights the common practices of risky sexual behaviors and relatively low rate of recent HIV testing among MSM in Cambodia. HIV education and social marketing should be expanded and tailored for MSM, specifically addressing the risk of unprotected anal intercourse and the importance of regular HIV testing for early enrolment in the care and treatment cascade.

Factors associated with induced abortion among female entertainment workers: a cross-sectional study in Cambodia

OBJECTIVE

To explore risk factors associated with induced abortion among sexually active female entertainment workers (FEWs) in Cambodia.

DESIGN

Cross-sectional study.

SETTING

Phnom Penh and Siem Reap, Cambodia.

PARTICIPANTS

This study included 556 FEWs aged 18-47 years randomly selected from entertainment establishments in the two cities in 2014 using a two-stage cluster sampling method. Data were collected through face-to-face interviews using a structured questionnaire.

PRIMARY OUTCOME MEASURE

History of induced abortion during the time working as a FEW.

RESULTS

Of the total sample, 45.6% reported currently using a contraceptive method with condom (42.4%) being the most common method, followed by pills (25.6%). One-fourth (25%) of the respondents reported having been pregnant at least once, and 21.4% reported having at least one induced abortion during the time working as a FEW. After controlling for other covariates in a multivariate logistic regression model, FEWs with a history of induced abortion remained significantly more likely to be currently working in a karaoke bar (AOR=1.75, 95% CI 1.10 to 2.78), to have worked longer as a FEW (AOR=1.42, 95% CI 1.06 to 1.43), to have had a greater number of sexual partners in the past 12 months (AOR=1.86, 95% CI 1.02 to 1.54), to be currently using a contraceptive method (AOR=1.52, 95% CI 1.01 to 2.29), to be able to find condoms when they needed them (AOR=2.03, 95% CI 1.09 to 3.82), and to report inconsistent condom use with non-commercial partners in the past 3 months (AOR=1.62, 95% CI 1.06 to 3.44).

CONCLUSIONS

This study highlights the high rates of unwanted pregnancies that ended in induced abortions among FEWs in Cambodia. Access of FEWs to quality sexual and reproductive healthcare services is deemed a high priority. Integrated interventions to improve sexual and reproductive health among these vulnerable women should be tailored to reach the most-at-risk groups.

Nickel doped nanohydroxyapatite: vascular endothelial growth factor inducing biomaterial for bone tissue engineering

Biomaterial induced activation of vascular endothelial growth factor (VEGF) pathway for angiogenesis is now gaining recognition as an effective option for tissue engineering.

Molecular docking and interactions of pueraria tuberosa with vascular endothelial growth factor receptors

Pueraria tuberosa is known for its therapeutic potentials in cardiovascular disorders, but its effect in angiogenesis has not been studied so far. In this study, a computational approach has been applied to elucidate the role of the phytochemicals in inhibition of angiogenesis through modulation of vascular endothelial growth factor receptors: Vascular endothelial growth factor receptor-1 and vascular endothelial growth factor receptor-2, major factors responsible for angiogenesis. Metabolite structures retrieved from PubChem and KNApSAcK – 3D databases, were docked using AutoDock4.2 tool. Hydrogen bond and molecular docking, absorption, distribution, metabolism and excretion and toxicity predictions were carried out using UCSF Chimera, LigPlot⁺ and PreADMET server, respectively. From the docking analysis, it was observed that puerarone and tuberostan had significant binding affinity for the intracellular kinase domain of vascular endothelial growth factor receptors-1 and vascular endothelial growth factor receptor-2 respectively. It is important to mention that both the phytochemicals shared similar interaction profile as that of standard inhibitors of vascular endothelial growth factor receptors. Also, both puerarone and tuberostan interacted with Lys861/Lys868 (adenosine 5’-triphosphate binding site of vascular endothelial growth factor receptors-1/vascular endothelial growth factor receptors-2), thus providing a clue that they may enforce their inhibitory effect by blocking the adenosine 5’-triphosphate binding domain of vascular endothelial growth factor receptors. Moreover, these molecules exhibited good drug-likeness, absorption, distribution, metabolism and excretion properties without any carcinogenic and toxic effects. The interaction pattern of the puerarone and tuberostan may provide a hint for a novel drug design for vascular endothelial growth factor tyrosine kinase receptors with better specificity to treat angiogenic disorders.

Pressure-induced structural changes and insulator-metal transition in layered bismuth triiodide, BiI3: a combined experimental and theoretical study

Noting that BiI3 and the well-known topological insulator (TI) Bi2Se3 have the same high symmetry parent structures, and that it is desirable to find a wide-band gap TI, we determine here the effects of pressure on the structure, phonons and electronic properties of rhombohedral BiI3. We report a pressure-induced insulator-metal transition near 1.5 GPa, using high pressure electrical resistivity and Raman measurements. X-ray diffraction studies, as a function of pressure, reveal a structural peculiarity of the BiI3 crystal, with a drastic drop in c/a ratio at 1.5 GPa, and a structural phase transition from rhombohedral to monoclinic structure at 8.8 GPa. Interestingly, the metallic phase, at relatively low pressures, exhibits minimal resistivity at low temperatures, similar to that in Bi2Se3. We corroborate these findings with first-principles calculations and suggest that the drop in the resistivity of BiI3 in the 1-3 GPa range of pressure arises possibly from the appearance of an intermediate crystal phase with a lower band-gap and hexagonal crystal structure. Calculated Born effective charges reveal the presence of metallic states in the structural vicinity of rhombohedral BiI3. Changes in the topology of the electronic bands of BiI3 with pressure, and a sharp decrease in the c/a ratio below 2 GPa, are shown to give rise to changes in the slope of phonon frequencies near that pressure.

Measurement of ψ(2S) meson production in pp collisions at [Formula: see text]

The differential cross-section for the inclusive production of ψ(2S) mesons in pp collisions at [Formula: see text] has been measured with the LHCb detector. The data sample corresponds to an integrated luminosity of 36 pb^-1. The ψ(2S) mesons are reconstructed in the decay channels ψ(2S)→μ⁺μ^- and ψ(2S)→J/ψπ⁺π^-, with the J/ψ meson decaying into two muons. Results are presented both for promptly produced ψ(2S) mesons and for those originating from b-hadron decays. In the kinematic range p_T(ψ(2S))≤16 GeV/c and 2<y(ψ(2S))≤4.5 we measure [Formula: see text] where the last uncertainty on the prompt cross-section is due to the unknown ψ(2S) polarization. Recent QCD calculations are found to be in good agreement with our measurements. Combining the present result with the LHCb J/ψ measurements we determine the inclusive branching fraction [Formula: see text] where the last uncertainty is due to the [Formula: see text], [Formula: see text] and [Formula: see text] branching fraction uncertainties.

Determination of the sign of the decay width difference in the B(s)(0) system

The interference between the K+ K- S-wave and P-wave amplitudes in B(s)(0) → J/ψK+ K- decays with the K+ K- pairs in the region around the ϕ(1020) resonance is used to determine the variation of the difference of the strong phase between these amplitudes as a function of K+ K- invariant mass. Combined with the results from our CP asymmetry measurement in B(s)(0) → J/ψϕ decays, we conclude that the B(s)(0) mass eigenstate that is almost CP = +1 is lighter and decays faster than the mass eigenstate that is almost CP = -1. This determines the sign of the decay width difference ΔΓ(s) ≡ Γ(L) - Γ(H) to be positive. Our result also resolves the ambiguity in the past measurements of the CP violating phase ϕ(s) to be close to zero rather than π. These conclusions are in agreement with the standard model expectations.

Opposite-side flavour tagging of B mesons at the LHCb experiment

The calibration and performance of the opposite-side flavour tagging algorithms used for the measurements of time-dependent asymmetries at the LHCb experiment are described. The algorithms have been developed using simulated events and optimized and calibrated with B⁺→J/ψK⁺, B⁰→J/ψK^∗0 and B⁰→D^∗-μ⁺ν_μ decay modes with 0.37 fb^-1 of data collected in pp collisions at [Formula: see text] during the 2011 physics run. The opposite-side tagging power is determined in the B⁺→J/ψK⁺ channel to be (2.10±0.08±0.24) %, where the first uncertainty is statistical and the second is systematic.

Measurement of production in collisions at [Formula: see text]

The production of ϒ(1S), ϒ(2S) and ϒ(3S) mesons in proton-proton collisions at the centre-of-mass energy of [Formula: see text] is studied with the LHCb detector. The analysis is based on a data sample of 25 pb-1 collected at the Large Hadron Collider. The ϒ mesons are reconstructed in the decay mode ϒ→μ+μ- and the signal yields are extracted from a fit to the μ+μ- invariant mass distributions. The differential production cross-sections times dimuon branching fractions are measured as a function of the ϒ transverse momentum pT and rapidity y, over the range pT <15 GeV/c and 2.0 Collapse

Differential branching fraction and angular analysis of the decay B0 → K*0 μ+ μ-

The angular distributions and the partial branching fraction of the decay B0 → K*0 μ+ μ- are studied by using an integrated luminosity of 0.37  fb(-1) of data collected with the LHCb detector. The forward-backward asymmetry of the muons, A(FB), the fraction of longitudinal polarization, F(L), and the partial branching fraction dB/dq2 are determined as a function of the dimuon invariant mass. The measurements are in good agreement with the standard model predictions and are the most precise to date. In the dimuon invariant mass squared range 1.00-6.00  GeV2/c4, the results are A(FB)=-0.06(-0.14)(+0.13)±0.04, F(L)=0.55±0.10±0.03, and dB/dq2=(0.42±0.06±0.03)×10(-7)  c4/GeV2. In each case, the first error is statistical and the second systematic.

First observation of the decays B(0) → D(+)K(-)π(+)π(-) and B(-) → D(0)K(-)π(+)π(-)

First observations of the Cabibbo-suppressed decays B(0) → D(+)K(-)π(+)π(-) and B(-) → D(0)K(-)π(+)π(-) are reported using 35 pb(-1) of data collected with the LHCb detector. Their branching fractions are measured with respect to the corresponding Cabibbo-favored decays, from which we obtain B(B(0) → D(+)K(-)π(+)π(-))/B(B(0) → D(+)π(-)π(+)π(-))=(5.9±1.1±0.5)×10(-2) and B(B(-) → D(0)K(-)π(+)π(-))/B(B(-) → D(0)π(-)π(+)π(-))=(9.4±1.3±0.9)×10(-2), where the uncertainties are statistical and systematic, respectively. The B(-) → D(0)K(-)π(+)π(-) decay is particularly interesting, as it can be used in a similar way to B(-) → D(0)K(-) to measure the Cabibbo-Kobayashi-Maskawa phase γ.
