RESUMEN

Transgender and nonbinary (trans) young adults report high rates of substance use and adverse mental health outcomes; however, few studies have examined how social, economic, and legal factors may contribute to health inequities in this population. Guided by the structural vulnerability framework, this study sought to explore structural needs and whether these needs were associated with substance use and mental health outcomes among trans young adults. Between 2019 and 2021, 215 trans young adults aged 18-29 from San Francisco Bay Area were recruited into a longitudinal study. Baseline data were used to examine bivariate and multivariable associations between structural needs and substance use and mental health outcomes. There were bivariate differences in the number of structural needs by education, income source, incarceration history, and ethnicity, and the number of unmet structural needs was associated with education and income source. After adjusting for sociodemographics, the number of structural needs was associated with daily marijuana use (AOR 1.29, 95% CI: 1.10-1.49) and suicidal ideation (AOR 1.24, 95% CI: 1.06-1.45), and the number of unmet structural needs was associated with daily marijuana use (AOR 1.30, 95% CI: 1. 10-1.55) and depressive symptoms (ß 2.00, 95% CI: 1.00-3.00). Additionally, both numbers of structural needs and unmet structural needs mediated the relationship between income source (traditional employment vs. other income only) and depressive symptoms (TIE ß 2.51, 95% CI: 0.99-4.04; ß 1.37, 95% CI: 0.23-2.52, respectively). Findings highlight a need for multisector efforts to address structural vulnerabilities among trans young adults.

RESUMEN

The baseline data of the intervention project for African American transgender women living with HIV showed that more than one-third of the participants having ever enrolled in HIV care had not received ART and that among those in ART, more than half reported their adherence to ART was poor. Those who had engaged in sex work, sold drugs, or experienced higher levels of transphobia were less likely to have enrolled in care. The qualitative interviews with participants who had completed the intervention or dropped out revealed barriers to enroll in care, such as community stigma and transphobia.

RESUMEN

Many transgender (trans) young adults migrate to urban enclaves with known infrastructures to fulfil gender affirmation needs such as obtaining trans-inclusive healthcare and support. This study sought to explore experiences of intranational migration (i.e. migration within a single country) for gender affirmation among trans young adults who relocated to San Francisco. A convenience sample of 61 trans young adults aged 18 to 29 (32% nonbinary, 28% trans women, and 40% trans men; 84% identified as a person of colour) participated in a one-time qualitative interview as part of a larger study. Thematic analysis was used to develop and refine the codes and themes. Three overarching themes became apparent regarding intranational migration and gender affirmation needs: (1) access to basic gender affirmation needs; (2) safety; and (3) the price of gender affirmation. Migration for gender affirmation and safety placed informants at risk for structural vulnerabilities including homelessness, unemployment and racism. Despite these structural vulnerabilities, participants were willing to "pay" the price in order to gain gender affirmation and safety. Findings underscore the importance of moving beyond individual-level risk factors to understand how unmet gender affirmation needs may place trans young adults in structurally vulnerable positions that can affect health and wellness.

RESUMEN

Most organisms, from Bacteria to Eukarya, synthesize UDP-N-acetylglucosamine (UDP-GlcNAc) from fructose-6-phosphate via a four-step reaction, and UDP-N-acetylgalactosamine (UDP-GalNAc) can only be synthesized from UDP-GlcNAc by UDP-GlcNAc 4-epimerase. In Archaea, the bacterial-type UDP-GlcNAc biosynthetic pathway was reported for Methanococcales. However, the complete biosynthetic pathways for UDP-GlcNAc and UDP-GalNAc present in one archaeal species are unidentified. Previous experimental analyses on enzymatic activities of the ST0452 protein, identified from the thermophilic crenarchaeon Sulfolobus tokodaii, predicted the presence of both a bacterial-type UDP-GlcNAc and an independent UDP-GalNAc biosynthetic pathway in this archaeon. In the present work, functional analyses revealed that the recombinant ST2186 protein possessed an glutamine:fructose-6-phosphate amidotransferase activity and that the recombinant ST0242 protein possessed a phosphoglucosamine-mutase activity. Along with the acetyltransferase and uridyltransferase activities of the ST0452 protein, the activities of the ST2186 and ST0242 proteins confirmed the presence of a bacterial-type UDP-GlcNAc biosynthetic pathway in S. tokodaii In contrast, the UDP-GlcNAc 4-epimerase homologue gene was not detected within the genomic data. Thus, it was expected that galactosamine-1-phosphate or galactosamine-6-phosphate (GalN-6-P) was provided by conversion of glucosamine-1-phosphate or glucosamine-6-phosphate (GlcN-6-P). A novel epimerase converting GlcN-6-P to GalN-6-P was detected in a cell extract of S. tokodaii, and the N-terminal sequence of the purified protein indicated that the novel epimerase was encoded by the ST2245 gene. Along with the ST0242 phosphogalactosamine-mutase activity, this observation confirmed the presence of a novel UDP-GalNAc biosynthetic pathway from GlcN-6-P in S. tokodaii Discovery of the novel pathway provides a new insight into the evolution of nucleotide sugar metabolic pathways.IMPORTANCE In this work, a novel protein capable of directly converting glucosamine-6-phosphate to galactosamine-6-phosphate was successfully purified from a cell extract of the thermophilic crenarchaeon Sulfolobus tokodaii Confirmation of this novel activity using the recombinant protein indicates that S. tokodaii possesses a novel UDP-GalNAc biosynthetic pathway derived from glucosamine-6-phosphate. The distributions of this and related genes indicate the presence of three different types of UDP-GalNAc biosynthetic pathways: a direct pathway using a novel enzyme and two conversion pathways from UDP-GlcNAc using known enzymes. Additionally, Crenarchaeota species lacking all three pathways were found, predicting the presence of one more unknown pathway. Identification of these novel proteins and pathways provides important insights into the evolution of nucleotide sugar biosynthesis, as well as being potentially important industrially.

RESUMEN

HIV risk among transgender women has been attributed to condomless sex with primary male partners. This study pilot tested a couples-focused HIV intervention program for transgender women and their primary male partners. We analyzed data from 56 transgender women and their male partners (n = 112 participants) who were randomized as a couple to one of two groups. Participants in the intervention group (27 couples) received 3 counseling sessions: 2 couples-focused sessions, which discussed relationship dynamics, communication, and HIV risk, and 1 individual-focused session on HIV prevention concerns. Participants in the control group (29 couples) received 1 session on general HIV prevention information delivered to both partners together. At 3-month follow-up, participants in the intervention reported lower odds of condomless sex with primary partners (OR 0.5, 95 % CI 0.3-1.0), reduced odds of engaging in sex with a casual partner (OR 0.3, 95 % CI 0.1-1.0), and reduction in the number of casual partners (B = -1.45, SE = 0.4) compared with the control group. Findings provide support for the feasibility and promise of a couples-focused HIV prevention intervention for transgender women and their primary male partners.

RESUMEN

INTRODUCTION: Research has demonstrated associations between reports of minority stressors and smoking behaviors among lesbian, gay, and bisexual populations; however, little is known about how minority stressors are related to smoking behaviors and cessation attempts among transgender women. The purpose of this study was twofold: (1) to examine the associations between transgender-based discrimination and smoking patterns among a sample of transgender women; and (2) to identify barriers to smoking cessation in a sample of transgender women with a history of smoking. METHODS: A community sample of 241 transgender women completed a one-time survey. Binary and multinomial logistic regression models examined associations between minority stressors and (1) smoking behaviors and (2) cessation attempts. Both models adjusted for income, education, race/ethnicity, recent sex work, HIV status, depression, alcohol use, and current hormone use. RESULTS: Overall, 83% of participants indicated that they had smoked a cigarette in the last month. Of these women, 62.3% reported daily smoking and 51.7% reported an unsuccessful quit attempt. Discrimination was positively associated with currently smoking (adjusted odds ratio [AOR] = 1.04, 95% confidence interval [CI]: 1.01, 1.08). Discrimination was positively associated with unsuccessful cessation (AOR = 1.03, 95% CI: 1.01, 1.18) and never attempting (AOR = 1.04, 95% CI: 1.01, 1.11) compared to successful cessation. Discrimination was also positively associated with never attempting compared to unsuccessful cessation (AOR = 1.01, 95% CI: 1.00, 1.03). CONCLUSIONS: Smoking cessation may be driven by unique transgender-related minority stressors, such as discrimination. Future research is warranted to address unique stigmatizing contexts when understanding and providing tailored intervention addressing smoking among transgender women.

RESUMEN

It is urgent to develop efficacious HIV prevention programs to curb the reported extremely high HIV prevalence and incidence among transgender women (male-to-female transgender persons) who reside in large cities in the USA. This study aimed to describe unprotected receptive anal sex (URAS) and unprotected insertive anal sex (UIAS) among high-risk transgender women in relation to partner types, psychosocial factors, and background variables. Based on purposive sampling from the targeted communities and AIDS service organizations in San Francisco and Oakland, a total of 573 transgender women who had a history of sex work were recruited and individually interviewed using a structured survey questionnaire. Significant correlates with URAS with primary, casual, and commercial sex partners were found (e.g., needs for social support, frequency of social support received, exposure to transphobia, self-esteem, economic pressure, norms toward practicing healthy behaviors, and self-efficacy toward practicing safe sex). Multiple logistic regression analyses revealed that transgender women who had engaged in URAS with commercial partners were more likely to have higher levels of transphobia or lower levels of the norms or self-efficacy to practice safe sex. Among the participants who did not have vaginoplasty (preoperative transgender women), 16.4% had engaged in insertive anal sex (IAS) with commercial partners in the past 30 days. The participants who were HIV positive and had engaged in IAS were more likely to be African-American or Caucasians, coinfected with sexually transmitted infections, or identified themselves as homosexual. Practices of IAS among transgender women have not been thoroughly investigated in relation to sexual and gender identity. UIAS with homosexual and bisexual men in addition to URAS may be a cause for high HIV incidence among transgender women. An HIV prevention intervention study must be developed and evaluated, which aims to reduce HIV-positive and -negative transgender women's URAS and UIAS.

RESUMEN

Recently, the number of indirect female sex workers (FSWs) who work at bars/clubs and massage parlors is substantially increasing in Thailand; however, there are huge gaps in knowledge about HIV risk behaviors among indirect FSWs. This study aimed to describe and understand HIV risk behaviors among Thai FSWs in Bangkok in relation to sociocultural factors and work environment (e.g., bars/clubs, massage parlors, brothels, and street). Based on venue-based purposive sampling methods, Thai FSWs were recruited for qualitative interviews (n=50) and survey interviews (n=205). Based on mixed methods, the study revealed that HIV risk and substance use behaviors among FSWs significantly differed depending on work venues, although there were no significant differences between work venues on some key risk behaviors (e.g., inconsistent condom use with primary partners and customers; willingness to engage in unsafe sex with customers). A multiple linear regression analysis revealed that FSWs who had used illicit drugs, were young, had low levels of self-esteem, or reported STIs had frequently engaged in unprotected vaginal sex with customers. Also, FSWs who worked at bars/clubs, were young, had higher income, or reported STIs had frequently engaged in sex with customers under the influence of alcohol. Qualitative interviews illustrated FSWs' alcohol and drug use due to their stressful life (e.g., long working hours and a large number of customers) and easy access to alcohol and drugs. FSWs had shown inaccurate knowledge about HIV prevention methods and engaged in risky behaviors, such as washing vagina with water or toothpaste after having had sex with customers. The HIV prevention strategies in Thailand need to be re-structured through implementing evidence-based HIV prevention intervention programs for FSWs, which must address sociocultural factors (e.g., self-esteem) and alcohol and drug use specific to work venues.

RESUMEN

Based on combined methods, this study investigated substance use and HIV risk behaviors among kathoey sex workers (KSWs) in Bangkok, Thailand. The study found that only half of the KSW participants reported having been tested for HIV, and that except for one participant, all others had not seen health care providers in the past 12 months. About one third of the participants reported having engaged in unprotected anal sex with customers in the past six months. Almost all participants reported alcohol use, as well as having had sex with customers under the influence of alcohol. The prevalence of marijuana and ecstasy use in the past 12 months was high (32 and 36%, respectively); as was for ketamine (20%) and non-injecting methamphetamine (yaba) use (10%). A multiple regression analysis showed that the participants who were post-operative status, had used illicit drugs, or had been abused by their father and brothers were less likely to use condoms for anal sex with customers. Three quarters of the participants sent money to their families and 35% of the participants expressed their willingness to engage in unsafe sex when customers offer extra money. The qualitative interviews revealed that many identified as girl or kathoey in early age and had been exposed to transphobia and violence from father and brothers. Some reported support for gender transition from their mothers. More than half of the participants currently had difficulties in living as kathoey, such as challenges in the job market and relationship with family members. Family obligation for sending money and the Buddhist concept of karma were discussed in relation to risk behaviors among KSWs. The study provided implications for facilitating HIV testing and developing future HIV prevention intervention programs for KSWs in Thailand.

RESUMEN

HIV risk behaviors and psychological well-being among men who have sex with men (MSM) in Kuala Lumpur, Malaysia (n = 140), were quantitatively described in relation to demographic and psychosocial factors. Most participants were tested for HIV and 41.4% reported living with HIV. Malay participants had significantly higher levels of depression (p < .05), homophobia (p < .01), and needs for social support (p < .01) than Chinese. More Chinese participants reported suicidal thoughts than Malaysians (p < .05). A multivariate analysis revealed that participants with gay/MSM-identified or had lower levels of self-esteem showed significantly higher levels of depression. Future intervention projects should address depression and mental health issues among MSM and strengthen self-esteem and social support through culturally competent support and individual counseling programs (e.g., addressing MSM's conflicts with religious beliefs and norms). Structural changes must be made incrementally to reduce homophobia against MSM in Malaysia while advocating human rights.

RESUMEN

OBJECTIVES: We determined racial/ethnic differences in social support and exposure to violence and transphobia, and explored correlates of depression among male-to-female transgender women with a history of sex work (THSW). METHODS: A total of 573 THSW who worked or resided in San Francisco or Oakland, California, were recruited through street outreach and referrals and completed individual interviews using a structured questionnaire. RESULTS: More than half of Latina and White participants were depressed on the basis of Center For Epidemiologic Studies Depression Scale scores. About three quarters of White participants reported ever having suicidal ideation, of whom 64% reported suicide attempts. Half of the participants reported being physically assaulted, and 38% reported being raped or sexually assaulted before age 18 years. White and African American participants reported transphobia experiences more frequently than did others. Social support, transphobia, suicidal ideation, and levels of income and education were significantly and independently correlated with depression. CONCLUSIONS: For THSW, psychological vulnerability must be addressed in counseling, support groups, and health promotion programs specifically tailored to race/ethnicity.

RESUMEN

Previous research has reported that transgender women are likely to be exposed to HIV through unprotected sex with a male primary partner. We examined prevalence and correlates of unprotected sex with a primary male partner in a sample of n = 174 transgender women. Participants completed surveys on demographic characteristics, relationship dynamics with their male primary partner, sexual behavior, substance use, and psychosocial factors. Overall, 41% reported HIV positive status, 13% had another sexually transmitted infection during the past year, and 34% had unprotected sex with a male primary partner during the past 3 months. Factors associated with unprotected sex with a primary partner included living with the partner, drug use, alcohol use, education level, low self-efficacy to use condoms, and perceived discrimination. Notably, 35% of transgender women in HIV-discordant primary partnerships had unprotected sex with their male primary partner during the past 3 months, and 18% of transgender women in HIV-positive concordant primary partnerships had unprotected sex with an outside partner during the past 3 months. HIV prevention interventions for transgender women must address risk behavior in the context of primary partnerships as well as sex with concurrent partners outside the relationship. Couples-focused interventions involving transgender women and their male primary partners can be particularly promising.

RESUMEN

Men who have sex with transgender women are a potentially high-risk population for HIV and other sexually transmitted infections (STIs). We administered structured quantitative surveys to 174 men whose primary partner was a transgender woman. We assessed men's demographic characteristics, sexual behaviors, substance use, and social-psychological factors, including condom use self-efficacy and depression. Overall, 19% reported being HIV-positive (8% had been diagnosed with AIDS), 11% had at least one other STI during the past year, and 16% reported being in a HIV serodiscordant relationship with their primary partner. In the past 3 months, 40% had unprotected anal or vaginal sex with any partner. In multivariate analysis, significant correlates of having unprotected sex included younger age, concurrent partnerships, alcohol intoxication, and low condom use self-efficacy; depression was marginally associated with having unprotected sex. Interventions are needed to reduce risk for HIV and other STIs among men who have sex with transgender women. Prevention programs for these men should build condom use self-efficacy and address the contributions of alcohol intoxication, concurrent sex partnerships, and depression to sexual risk behavior.

RESUMEN

Very few studies have been conducted to investigate HIV risk and protective behaviors in relation to psychosocial factors among Asian and Pacific Islander (API) MSM whose HIV/AIDS prevalence is lower than those of other racial/ethnic groups. This study, based on an online survey targeting API MSM in California revealed that API MSM often met sex partners online and that psychosocial factors (e.g., homophobia and identity with API gay community) were correlated with condomless receptive anal sex (RAS) with casual partners. In particular, an Asian cultural construct, interdependency, was correlated with condom use for RAS; that is, those who consider sex partners' health and value harmony tend to engage in safe sex. This finding sheds light on re-thinking the current over-emphasis on assertiveness and self-responsibility to keep free from HIV/STIs during negotiation with partners. Future STI prevention programs for API MSM should incorporate Asian cultural constructs and target specific risk groups.

RESUMEN

A total of 249 Japanese nationals - tourists (n = 107), students (n = 98), and temporary workers (n = 44) - were recruited at the targeted community venues in Honolulu, Hawaii, and completed a structured survey questionnaire. Reported lifetime sexually transmitted diseases, or STDs infection (10% male and 20% female participants), and HIV infection rates (7%, 2 out of 31 persons tested) were high. Male participants were more likely to practice safe sex with female sex workers than with steady and casual female partners both in Japan and Hawaii. More than 80% of the participants reported having had sex under the influence of alcohol. Multivariate analysis revealed that positive attitudes toward drug use and negative attitudes toward condom use were significantly correlated with the frequency of sex under the influence of drugs with steady partners in the past 12 months. Future HIV/STD prevention intervention programs must target Japanese youths who are planning to visit Hawaii or elsewhere abroad, as well as Japanese high-risk groups (e.g., temporary workers in Hawaii), and provide information about HIV/STD prevention in relation to substance use.

RESUMEN

Kathoey (male-to-female transgender) sex workers (KSW) in Thailand are at high risk for sexually transmitted infections; however, few qualitative studies have been conducted to understand the sociocultural context of engaging in HIV risk behaviors. A total of 24 participants were purposively sampled in Bangkok based on KSW work venues and substance use. Results revealed the importance of participants' understanding of the self in relation to establishing economic independence through sex work, which could then be used to re-establish support from family, who often have not accepted a son's gender transition. Participants linked being kathoey to a belief in fate but did not view engagement in sex work in the same way. Different sex work venues exposed KSW to different risky situations. HIV prevention programs for kathoey must address the importance of economic security and its relation to social support and gender transition within a cultural- and work-environment-specific framework.

RESUMEN

High prevalence of psychological distress, including greater depression, lower self-esteem, and suicidal ideation, has been documented across numerous samples of transgender women and has been attributed to high rates of discrimination and violence. According to the gender affirmation framework (Sevelius, 2013), access to sources of gender-affirmative support can offset such negative psychological effects of social oppression. However, critical questions remain unanswered in regards to how and which aspects of gender affirmation are related to psychological well-being. The aims of this study were to investigate the associations between three discrete areas of gender affirmation (psychological, medical, and social) and participants' reports of psychological well-being. A community sample of 573 transgender women with a history of sex work completed a one-time self-report survey that assessed demographic characteristics, gender affirmation, and mental health outcomes. In multivariate models, we found that social, psychological, and medical gender affirmation were significant predictors of lower depression and higher self-esteem while no domains of affirmation were significantly associated with suicidal ideation. Findings support the need for accessible and affordable transitioning resources for transgender women in order to promote better quality of life among an already vulnerable population. As the gender affirmation framework posits, the personal experience of feeling affirmed as a transgender person results from individuals' subjective perceptions of need along multiple dimensions of gender affirmation. Personalized assessment of gender affirmation may thus be a useful component of counseling and service provision for transgender women.

RESUMEN

Glycerol is a by-product in the biodiesel production process and considered as one of the prospective carbon sources for microbial fermentation including lactic acid fermentation, which has received considerable interest due to its potential application. Enterococcus faecalis isolated in our laboratory produced optically pure L-lactic acid from glycerol in the presence of acetic acid. Gas chromatography-mass spectrometry analysis using [1, 2-(13)C2] acetic acid proved that the E. faecalis strain QU 11 was capable of converting acetic acid to ethanol during lactic acid fermentation of glycerol. This indicated that strain QU 11 restored the redox balance by oxidizing excess NADH though acetic acid metabolism, during ethanol production, which resulted in lactic acid production from glycerol. The effects of pH control and substrate concentration on lactic acid fermentation were also investigated. Glycerol and acetic acid concentrations of 30 g/L and 10 g/L, respectively, were expected to be appropriate for lactic acid fermentation of glycerol by strain QU 11 at a pH of 6.5. Furthermore, fed-batch fermentation with 30 g/L glycerol and 10 g/L acetic acid wholly exhibited the best performance including lactic acid production (55.3 g/L), lactic acid yield (0.991 mol-lactic acid/mol-glycerol), total yield [1.08 mol-(lactic acid and ethanol)]/mol-(glycerol and acetic acid)], and total carbon yield [1.06 C-mol-(lactic acid and ethanol)/C-mol-(glycerol and acetic acid)] of lactic acid and ethanol. In summary, the strain QU 11 successfully produced lactic acid from glycerol with acetic acid metabolism, and an efficient fermentation system was established without carbon loss.

RESUMEN

This study investigates cognitive, cultural, and contextual factors that influence HIV-related risk behaviors among Asian women who engage in sex work at massage parlors in San Francisco. Focus groups and qualitative interviews were conducted for Vietnamese and Thai masseuses and massage parlor owners/managers. Economic pressure as well as subjective evaluation of customers for the risk of HIV/STD infection increase unprotected sexual behaviors among Asian masseuses. Massage parlor owners/managers do not establish a clear policy for condom use at their parlors. Consequently, male customers often manipulate their intention not to use a condom while negotiating with masseuses. HIV/STD prevention intervention programs should address specific risks and needs for Asian masseuses, owners/managers, and male customers in order to promote health and well being among Asian masseuses who have been neglected by public health and social services.

RESUMEN

PURPOSE: The San Francisco Bay Area attracts people from all over the country due to the perception of lesbian, gay, bisexual, and transgender (LGBT) acceptance and affirmation. African-American transgender women are severely marginalized across society and as such have many unmet health and social service needs. This study sought to quantitatively assess unmet needs among African-American transgender women with a history of sex work by comparing residents of Oakland versus San Francisco. METHODS: A total of 235 African-American transgender women were recruited from San Francisco (n=112) and Oakland (n=123) through community outreach and in collaboration with AIDS service organizations. Participants were surveyed regarding basic, health, and social needs and HIV risk behaviors. Pearson Chi-squared tests and a linear regression model examined associations between city of residence and unmet needs. RESULTS: While participants from both cities reported unmet needs, Oakland participants had a greater number of unmet needs in receiving basic assistance, mental health treatment, and health care services. Oakland participants also reported less transgender community identification but higher social support from the family. CONCLUSION: These findings demonstrate the enormity of African-American transgender women's needs within the Bay Area. Greater resources are needed for social service provision targeting this marginalized group of people, particularly in Oakland.
