Abstract
BACKGROUND Due to the restricted availability of health services in Thailand, there are still some transgender women (TGW) who do not have access to HIV counseling and testing. Telehealth, which is accessible to individuals who are reluctant to undergo face-to-face interviewing, played an especially important role during the COVID-19 epidemic. The objectives of this study are to compare the characteristics, pattern of accessing HIV testing, and the HIV-positive rates of TGW between the face-to-face and telemedicine services. METHODS We conducted a cross-sectional study to compare the access to HIV testing and the HIV-positive rates among TGW via face-to-face service and telemedicine services and examined the influence of potential associated factors on the risk of being HIV-positive. RESULTS Of the 637 TGW participants, 26 (4.1%) were HIV-positive. Accessing the telemedicine service increased in the third and fourth COVID-19 waves (28.1% in the first and second vs. 71.9% in the third and fourth). There was no difference in the risk of being HIV-positive between the types of service. Having sex work experience (adjusted odds ratio (aOR) = 5.92; 95% confidence interval (CI): 1.57-22.30) and either never having been or tested more than 1 year ago were independently significantly associated with a higher risk of being HIV-positive (aOR = 4.05; 95% CI: 1.11-14.77). CONCLUSION The telemedicine service became more popular among TGW during the COVID-19 pandemic and was not related to a higher risk of being HIV-positive. Moreover, it proved to be an effective alternative channel to access HIV testing, especially for intravenous drug users. Sex work experience and irregular HIV testing are key risk factors for HIV infection in TGW seeking either the telemedicine or face-to-face service.

Abstract
BACKGROUND To date, there have been no major studies of alcohol-associated unnatural deaths in Thailand or South East Asia. Thailand leads South East Asia in per capita alcohol consumption. The objectives of this study were to determine the incidence of alcohol-associated unnatural deaths in Thailand and their relation to post-mortem blood alcohol concentration (BAC); to investigate correlations between BAC and selected demographic variables; and to evaluate the incidence of co-use of alcohol and illicit substances. METHODS We conducted a retrospective register-based study of alcohol-investigated unnatural deaths in Thailand for the period 2007-2019. The core study sample (n = 77,006) was derived from a Thai government computerized database of unnatural-death autopsies. RESULTS Of the total autopsy sample 32.49% was alcohol positive (BAC ≥0.20 g/L). The rate at which male autopsy cases were alcohol positive (35.52%) was approximately twice that of female autopsy cases (16.62%), with males having significantly higher median BAC levels, 1.64 and 1.31 g/L, respectively. The incidence of female alcohol-positive cases with extremely high BACs (≥3.50 g/L) was comparable to that of male alcohol-positive autopsies. The rates at which victims of accidents, homicides, and suicides were alcohol positive were 42.44%, 38.81%, and 33.25%, respectively. Drowning fatalities had the highest rate of alcohol detection (49.12%) and the highest median BAC (2.47 g/L). The next highest rate (48.47%) was among road traffic fatalities (RTFs, BAC 1.92 g/L), which accounted for about one-half of all RTFs and one-third of all alcohol-positive autopsies. Of the total alcohol-positive population, 8.33% tested positive for illicit substances, most commonly methamphetamine/amphetamine. CONCLUSIONS BAC results for the majority of male and female alcohol-positive victims exceeded the generally accepted threshold for Heavy Episodic Drinking (0.8 g/L) and provided a rare BAC-documented (≥3.50 g/L) example of gender parity in the incidence of heavy alcohol consumption. The median BAC value for alcohol-positive RTFs (1.92 g/L) was about 10% higher than in studies in most other countries and about four times greater the Thai legal limit for motor-vehicle operation (0.50 g/L).

Abstract
OBJECTIVE We study factors affecting neutrophil-to-lymphocyte ratio (NLR) and its changes throughout the treatment (ΔNLR) of nasopharyngeal carcinoma (NPC) underwent chemoradiotherapy (CCRT) followed by adjuvant chemotherapy (AC) and oncological outcomes including overall survival (OS) and disease-free survival (DFS). METHODS Data from 81 NPC patients was retrospectively evaluated. NLRs were obtained from first week of CCRT (pre-CCRT), last week of CCRT (end-CCRT), and at last cycle of AC (end-AC). Pre-CCRT NLR was categorized into "low" and "high". End-CCRT and end-AC ΔNLRs were divided into "increased" and "decreased" based on NLR at these two timepoints relative to the value at pre-CCRT. Associations between sex, age, cancer stage and NLR, ΔNLRs were investigated. OS and DFS were reported. RESULTS Median NLR at pre-CCRT (2.47) was lower than NLR at end-CCRT (6.29) and end-AC (3.77) (P-value = 0.043). Advanced cancer stage associated with high pre-CCRT NLR (P-value = 0.047). Male gender was associated with "increased" end-CCRT ΔNLR, whereas male gender and age ≤51 were associated with "increased" end-AC ΔNLR. Three-year OS and DFS rates were 85.25% and 76.39%, respectively. There were no statistically significant differences observed in OS and DFS among groups categorized by pre-CCRT NLR, ΔNLRs, gender, age, and cancer stage. CONCLUSIONS NLR increases during NPC treatment. Advanced staging is associated with higher baseline NLR. Increased ΔNLR is associated with male gender at end-CCRT and male gender with age ≤51 years at end-AC. No relation between NLR and its dynamic change with either OS or DFS was demonstrated.

Abstract
Purpose The objective of this study is to identify factors associated with depression and the quality of life of Thai transgender women (TGW) from Chiang Mai province, Thailand, who have experienced being bullied. Methods We conducted the study on TGW ≥18 years of age in Chiang Mai province, Thailand, from May to November 2020. Data were collected using self-reporting questionnaires at the MPlus Chiang Mai foundation. Binary logistic regression analysis was used to examine the association between potential factors associated with depression and quality of life. Results Of the 205 TGW individuals who participated in this study with a median age of 24 years, most were students (43.3%), and the most common type of bullying was verbal (30.9%). The prevalence of depression among the TGW participants was 30.1%, although most of the participants had a good overall quality of life (53.4%). The impacts of being physically bullied at primary or secondary school and experiencing cyberbullying at primary school were associated with a higher risk of depression. The impacts of being cyberbullied within the previous 6 months and physically bullied at primary or secondary school were associated with a fair quality of life. Conclusion Our results show that many TGW had experienced bullying in their childhood and within the previous 6 months. Screening for experiences of having been bullied and psychological problems might be advantageous for the wellbeing of TGW, while counseling programs or psychotherapy should be provided for those who have experienced bullying to mitigate depression and improve their quality of life.

Abstract
BACKGROUND Although discriminatory experiences of transgender people seeking healthcare services have been well-documented in several studies, differentiating those experiences based on gender identity/expression and related factors has been limited. The aim of this study was to compare the characteristics, experiences, attitude, and expectation toward accessing healthcare service and healthcare providers of transgender women and transgender men in Thailand. METHODS A cross-sectional study was conducted from October 2017 to March 2018. The data were collected from transgender women and transgender men aged ≥ 18 years old who lived in Thailand using online platform via different websites and Facebook pages of local transgender group. Binary logistic regression was used to identify the factors related to the study outcomes. RESULTS Of 186 transgender people who responded to the questionnaire and were eligible for the study, 73.7% (95% confidence interval [CI] = 66.7-79.8) were transgender women and 26.3% (95% CI = 20.2-33.3) were transgender men. Transgender women were more likely to seek general healthcare from non-traditional healthcare services (crude odds ratio [cOR] = 4.28; 95% CI = 1.55-11.81; P = 0.005), buy hormone treatment from non-traditional healthcare services (cOR = 3.89; 95% CI = 1.18-12.83; P = 0.026), and receive healthcare counseling from non-traditional healthcare providers (cOR = 5.16; 95% CI = 1.42-18.75; P = 0.013) than transgender men. According to the results of applying a multivariable model, transgender respondents who did not know that gender-affirming healthcare services existed in Thailand were more unwilling to receive counseling from gender-affirming healthcare providers than those who did (adjusted odds ratio = 3.70; 95% CI = 1.11-12.36; P = 0.033). CONCLUSIONS The findings from this cross-sectional study indicate that transgender women are more likely than transgender men to receive general healthcare and hormone treatment from non-traditional healthcare services and buy hormone treatment without a physician's supervision. We also found approximately 15% of transgender individuals who did not receive gender-affirming counseling services. Continuing to improve access to care for the transgender community, increasing public relations channels may encourage transgender people to access more healthcare services.

Abstract
Although HIV pre-exposure prophylaxis (PrEP) is free in Thailand, many transgender women discontinue taking it after initiation. We determined the loss to follow-up (LTFU) rate of transgender women who initiated PrEP at the Mplus Foundation, Chiang Mai, Thailand, and identified associated risk factors using Cox proportional hazard models. Of 235 participants who initiated PrEP, 59 (55%) out of 108 remaining participants had reactive syphilis. The LTFU rate at 6 months was 38% (95% confidence interval [CI]: 29-48%). Multivariable analysis indicates that LTFU is independently associated with age ≥ 26 years old (adjusted hazard ratio [aHR] = 2.09; 95% CI: 1.06-4.14) and reactive syphilis (aHR = 1.98; 95% CI:1.01-3.88). Delayed appointment scheduling by the PrEP providers and the syphilis clinic was associated with transgender women having reactive syphilis, and the lockdown policy during the COVID-19 pandemic might have influenced them to discontinue PrEP and their subsequent LTFU.

Abstract
Working on outdoor farms affects elderly farmers' health, especially those who have chronic diseases. This study aims to identify the risk factors related to perceived hot conditions on outdoor farms among elderly Thai farmers aged 60 years and older with chronic diseases. A cross-sectional study was conducted on 352 elderly farmers in nine sub-districts of Nong Suea District, Pathum Thani Province, Thailand via convenience sampling. Questionnaires were used as instruments to gather data about demographic and working factors. The risk factors associated with elderly Thai farmers' perceptions of hot conditions on outdoor farms were identified by using binary logistic regression. The most common chronic illnesses were hypertension (35.8%), heart disease (34.4%), and diabetes mellitus (24.5%). More than 60.5% of the participants perceived their hot conditions to be high. The results of binary logistic regression show that low income and work duration ≤8.0 hours per day were risk factors related to perceived hot conditions on outdoor farms (P value < 0.05). These findings may be used by relevant authorities to support elderly farmers by emphasizing the importance of individual and work-related factors. Relevant government agencies should consider formulating working standards in hot conditions specifically for elderly farm workers.

Abstract
BACKGROUND Immune-enhancing nutrition (IMN) strengthens the systematic inflammatory response and the immune system. Neutrophil to lymphocyte ratio (NLR) and absolute lymphocyte count (ALC) are affected during cancer therapies. OBJECTIVE We carried out an analysis of the dynamic changes in NLR and ALC over time in cancer patients with or without IMN supplementation. METHODS 88 cancer patients receiving concurrent chemoradiotherapy (CCRT) were randomized into regular diet group, and regular diet and IMN group.Generalized estimation equation models were used to assess associations between patient's characteristics, IMN, and dynamic changes in NLR and ALC over time. RESULTS NLR and ALC at preCCRT were significantly associated with dynamic changes in NLR (adjusted β= 1.08, 95% confidence interval [CI]: 0.64-1.52) and ALC (adjusted β= 0.41, 95% CI: 0.36-0.46). The magnitudes of the NLR and ALC changes through CCRT were lower in patients receiving IMN, although the differences were not statistically significant except ALC at the end of CCRT in head and neck cancer patients (P= 0.023). CONCLUSION Dynamic negative changes in both markers were demonstrated throughout CCRT. There were non-significant trend in promising changes in both NLR and ALC values in the whole group in IMN supplementation.

Abstract
Human immunodeficiency virus (HIV) infection is still a major cause of death in Thais and new cases of infection are still emerging among the key population comprising men who have sex with men (MSM), sex workers and their clients, and transgender women (TGW) and people who inject drugs. The objective of this study was to compare the incidence of HIV infection between MSM and TGW who were tested at stand-alone and mobile HIV voluntary counseling and testing (VCT) centers and to identify factors associated with HIV-positive individuals from the two services. We conducted an observational study using MSM and TGW individuals with unknown HIV status from the databases at a stand-alone center and a mobile VCT belonging to the MPlus in Chiang Mai province, Thailand. Factors associated with HIV-positive status were identified using logistic regression model. HIV VCT data were obtained for 6971 individuals at both MPlus center and mobile care unit. Among 3033 and 3938 clients tested at each facility, respectively, 168 (5.6%) and 101 (2.6%) clients were HIV positive. Individuals tested at the stand-alone centers were at a 1.91-fold higher risk of being HIV positive compared with those tested at the mobile VCT unit. Individuals who were 20-24 or >24 years old, sex workers, or sexually transmitted infection positive were more likely to be HIV positive. Our results show the beneficial effect of mobile HIV VCT facilities that enable testing of more of the at-risk population. Developing mobile VCT activities that attract a particular target population is needed to be able to reach the 90-90-90 goals. This study was approved by the Ethics Committee of the Faculty of Medicine, Chiang Mai University (0BG-2562-06418).

Abstract
INTRODUCTION In recent decades, the developing countries of Southeast Asia, including the Lao People's Democratic Republic (Lao PDR), have experienced a rapid growth of their urban population. Partly as a result of that, issues of undernutrition and overnutrition became a significant public health problem. OBJECTIVE To examine the prevalence of overweight and obesity and their related factors, among the school-attending adolescents in the Lao capital of Vientiane. METHODS A cross-sectional data on 300 adolescents aged 15-19 were collected during the months of March, April, and May 2018 by means of a self-administrated questionnaire. Anthropometric measurements were used to obtain data on height and weight. Pearson's chi-squared test, Fisher exact tests, and univariable and multivariable logistic regressions were applied in the course of the statistical analysis. RESULTS The study found a high prevalence of overweight/obesity (23.3%) and thinness (10.3%). Poor eating habits were noted in 67.0% of adolescents, even though 78.0% of them had a good knowledge of nutrition. Factors significantly associated with the overweight/obesity were low physical activities (aOR = 18.3; 95% CI: 5.51-60.66) and adolescents living with their guardians (aOR = 0.25; 95% CI: 0.08-0.79). Results also indicated that, in 47.3% of the cases, teachers, acting as a source of health and nutrition information, can prevent the risk of adolescents' overweight/obesity (aOR = 2.05, 95% CI = 1.11-3.80) but not their thinness (aOR = 0.4, 95% CI = 0.17-0.88). CONCLUSIONS Laotian adolescents are facing the spectrum of malnutrition in urban areas. To improve adolescents' nutritional status, there is a need for a collaborative approach of public health agencies that would address the issues of an effective food and nutrition policy. The school curricula should also include programs on nutrition and physical education.

Abstract
Background To access the long term relationship between efavirenz plasma concentrations and evolution of HIV RNA loads and CD4 cell counts in children. Methods Retrospective analysis of data from HIV-infected children on first line efavirenz-containing regimen. A population pharmacokinetic-pharmacodynamic (PK-PD) model was developed to describe the evolution of HIV RNA load and CD4 cell count (efficacy outcomes) in relation to efavirenz plasma concentration. Individual CYP2B6 516 G>T genotype data were not available for this analysis. A score (ISEFV) quantifying the effect of efavirenz concentrations on the long-term HIV replication was calculated from efavirenz concentrations and PD parameters and, a value of ISEFV below which HIV replication is likely not suppressed was determined. Cox proportional hazards regression models were used to assess the association of the risk of viral replication with ISEFV, and with efavirenz mid-dose concentration(C12). Results At treatment initiation, median (interquartile range, IQR) age was 8 years (5 to 10), body weight 17 kg (14 to 23), HIV RNA load 5.1 log10 copies/mL (4.6 to 5.4), and CD4 cell count 71 cells/mm3. A model of PK-PD viral dynamics assuming that efavirenz decreases the rate of infected host cells adequately described the relationship of interest. After adjusting for age, baseline HIV RNA load and CD4 cell counts an ISEFV <85% was significantly associated with a higher risk of viral replication (p-value <0.001) while no significant association was observed with C12 <1.0 mg/L. Conclusion The ISEFV score was a good predictor of viral replication in children on efavirenz-based treatment.

Abstract
Efavirenz use is associated with changes in cholesterol concentrations, but it is unclear whether this effect is related to drug concentrations. Using efavirenz and cholesterol plasma concentrations measured in 87 antiretroviral-naive children in Thailand, we assessed indirect response models to describe the evolution of high- and low-density lipoprotein (HDL, LDL) cholesterol concentrations in relation to efavirenz plasma concentrations over time where efavirenz was assumed to either stimulate cholesterol production or inhibit its elimination. Simulations of cholesterol evolution for children with different average efavirenz concentrations (Cav ) according to their assumed status of "fast" or "slow" metabolizers of efavirenz were performed. At treatment initiation, children's median (interquartile range, IQR) age was 8 years (5 to 10), body mass index z-score 0.01 (-1.05 to 1.44), HDL 31 mg/dL (24 to 44), and LDL 83 mg/dL (69 to 100). Median (IQR) efavirenz Cav was 1.7 mg/L (1.3 to 2.1) during the period of observation. The best model describing the evolution of HDL and LDL cholesterol concentrations over time assumed that efavirenz inhibited their elimination. HDL concentrations increase over 5 years, whereas LDL concentrations increased only during the first 4 months and then returned to baseline levels afterward. Simulations predicted that, after 3 years, HDL would increase to 63 mg/dL in "fast" metabolizers and 97 mg/dL in "slow" metabolizers of efavirenz. The population pharmacokinetic-pharmacodynamic (PK-PD) model shows that favorable HDL cholesterol changes can be expected in children with current efavirenz dosing guidelines over 5 years of treatment.
