RESUMEN

INTRODUCTION: This study examined the relative efficacy of growth factor therapies in healing diabetes-related foot ulcers (DFU). METHODS: PubMed and Cochrane databases were searched for randomized controlled trials testing growth factor therapies for treating DFU. The primary outcome was complete wound closure. Results were reported as relative risk (RR) ± 95% credible intervals (CrI). The risk of bias was assessed using Cochrane's RoB-2 tool. RESULTS: A total of 31 RCTs involving 2174 participants were included. Only 13 of the trials (n = 924) reported on the aetiology of the ulcers (85.4% neuropathic and 14.6% ischaemic). Epidermal growth factor (RR 3.83; 95% CrI 1.81, 9.10), plasma-rich protein (PRP) (RR 3.36; 95% CrI 1.66, 8.03) and platelet-derived growth factor (PDGF) (RR 2.47; 95% CrI 1.23, 5.17) significantly improved the likelihood of complete ulcer healing compared to control. Sub-analyses suggested that PRP (3 trials - RR 9.69; 95% CrI 1.37, 103.37) and PDGF (6 trials - RR 2.22; 95% CrI 1.12, 5.19) significantly improved the likelihood of wound closure amongst trial mainly recruiting participants with neuropathic ulcers. Eleven trials had a low risk of bias, 9 had some concerns and 11 had a high risk of bias. Sub-analysis of trials with a low risk of bias suggested that none of the growth factors significantly improved ulcer healing compared with control. DISCUSSION: This network meta-analysis found low-quality evidence that Epidermal growth factor, PRP and PDGF therapy improved DFU healing likelihood compared with control. Larger well-designed trials are needed.

RESUMEN

BACKGROUND: The Philippines is experiencing an HIV crisis and is considering implementing pre-exposure prophylaxis (PrEP) as a national public health strategy for HIV prevention for cisgender men who have sex with men (cis-MSM). However, critical information on the awareness of PrEP among cis-MSM is needed to roll out this public health initiative. OBJECTIVE: This study aims to assess PrEP awareness and related correlates (ie, sociodemographic variables, social factors, and health care access and use) among Filipino cis-MSM. METHODS: We conducted a web-based survey with Filipino cis-MSM (n=179) residing in the cities of Manila and Cebu, Philippines. Multivariable analysis procedures were performed to examine the factors associated with PrEP awareness. RESULTS: Our sample demonstrated high awareness (134/179, 74.9%) and interest (159/179, 88.8%) in taking PrEP. The adjusted model showed that greater odds of PrEP awareness were associated with having a college education or higher versus a high school education or lower (adjusted odds ratio [aOR] 7.30, 95% CI 1.01-52.47), earning between PHP 10,000 (US $198.6) and PHP 20,000 (US $397.2) versus

RESUMEN

Background: This study aimed to investigate whether home exercise programs informed by wearable activity monitors improved walking ability of patients with peripheral artery disease (PAD). Methods: A systematic literature search was performed to identify randomised controlled trials (RCT) testing home exercise that were or were not informed by wearable activity monitors. The primary outcome was the change in walking distance measured by a six-minute walking test or treadmill test over the course of the trial. Network meta-analysis (NMA) was performed using the gemtc R statistical package. The risk of bias was assessed using Cochrane tool for assessing risk of bias in RCTs (RoB 2.0). Results: A total of 14 RCTs involving 1544 participants were included. Nine trials used wearable activity monitors to inform the home exercise program tested, while five trials did not use wearable activity monitors to inform the home exercise program tested. Overall quality assessment showed 12 trials to be at low risk of bias and two trials at high risk of bias. Home exercise programs informed by wearable activity monitors significantly improved walking distance compared to non-exercise controls (Mean difference, MD: 32.8 m [95% credible interval, CrI: 6.1, 71.0]) but not compared to home exercise programs not informed by wearable activity monitors (MD: 4.7 m [95% CrI: -38.5, 55.4]). Conclusions: Home exercise informed by wearable activity monitors improve walking ability of patients with PAD. It is, however, unclear if activity monitoring informed exercise programs are more effective than exercise programs not using activity monitors.

RESUMEN

A large proportion of HIV infections among men who have sex with men occur within primary partnerships, however, there is a lack of research focused on serodiscordant male couples. We used baseline data collected as part of Project Stronger Together-a randomized controlled trial to improve treatment outcomes among 155 serodiscordant male couples. We described engagement in HIV care/prevention using the HIV treatment cascade and PrEP care continuum. Among partners living with HIV, 86.5% were linked to care, 77.4% retained in care, 81.3% prescribed ART, 60.7% adherent, and 67.7%virally suppressed. Among HIV-negative partners, 62.6% were willing to take PrEP, 48.4% had ever taken PrEP, and 26.5% were adherent to PrEP. Black partners living with HIV had lower odds of being virally suppressed compared to White partners. Our findings provide evidence to suggest designing programs to address the racial disparities in viral suppression, addressing barriers to HIV prevention/treatment, and improving PrEP education.

RESUMEN

Sexual agreements (SAs)-guidelines that outline what type of sexual behaviors are permissible with sexual partners outside of their primary relationship-are often negotiated within same-sex male relationships to reduce their risk for HIV infection. However, HIV risk is not only a function of sexual behavior, but is also affected by factors such as antiretroviral therapy (ART) adherence. We examined whether HIV-positive partners in serodiscordant male couples who have better communication about SAs and report concordant SAs with their partners have greater odds of being adherent to ART to not only improve their health, but to also reduce the risk of transmitting HIV to partners. We analyzed longitudinal data from 135 HIV-positive partners in serodiscordant male couples recruited from Atlanta, GA, Boston, MA, and Chicago, IL to examine the relationship between optimal ART adherence and two independent variables: communication about SAs and if the couples have discrepant SAs. HIV-positive male partners who reported high levels of communication regarding SAs had nearly three times the odds of optimal adherence to ART compared to those who reported lower levels. The HIV-positive partners with discrepant SAs with their male partner had approximately half the odds of optimal adherence to ART compared to those with concordant SAs. Our findings suggest that integrating communication skills training into dyad-level HIV interventions to improve communication regarding HIV may provide more opportunities for couples to discuss ways of reducing the risk of HIV transmission. Couples may benefit from interventions that assist them in composing SAs.

RESUMEN

Nigerian gay, bisexual and other men who have sex with men (GBMSM) experience negative psychosocial health problems, which may increase their risk for HIV infection. Few studies have explored the syndemic effect of co-occurring psychosocial health problems on HIV sexual risk among Nigerian GBMSM. We investigated the co-occurrence of syndemic psychosocial health problems and their synergistic effect on HIV risk behaviors. We assessed depressive symptoms, post-traumatic stress disorder, alcohol dependence, tobacco use, and hard-drug use. The outcome variables were the number of male sexual partners and consistent condom use. In a multivariable model, experiencing 4 or more psychosocial health problems - compared to experience none or one psychosocial health problem - was significantly associated with increasing number of male sexual partners. We found no statistically significant association between the number of syndemic psychosocial health problems and consistent condom use. Our study findings provides evidence of a synergistic relationship between negative psychosocial health factors and HIV sexual risk behavior. These findings underscore the importance of developing HIV prevention programming aimed at reducing HIV transmission risk that incorporate substance use and mental health treatments, in order to improve the overall health and quality of life for Nigerian GBMSM.

RESUMEN

BACKGROUND: Medicaid expansion has led to unique opportunities for sexually transmitted disease (STD) clinics to improve the sustainability of services by billing insurance. We evaluated changes in patient visits after the implementation of insurance billing at a STD clinic in a Medicaid expansion state. METHODS: The Rhode Island STD Clinic offered HIV/STD screening services at no cost to patients until October 2016, when insurance billing was implemented. Care for uninsured patients was still provided for free. We compared the clinic visits in the preinsurance period with the postinsurance period using t-tests, Poisson regressions, and a logistic regression. RESULTS: A total of 5560 patients were seen during the preinsurance (n = 2555) and postinsurance (n = 3005) periods. Compared with the preinsurance period, the postinsurance period had a significantly higher average number of patient visits/month (212.9 vs. 250.4, P = 0.0016), including among patients who were black (36.8 vs. 50.3, P = 0.0029), Hispanic/Latino (50.8 vs. 65.8, P = 0.0018), and insured (106.3 vs. 130.1, P = 0.0025). The growth rate of uninsured (+0.10 vs. +4.11, P = 0.0026) and new patients (-4.28 vs. +1.07, P = 0.0007) also increased between the two periods. New patients whose first visit was before the billing change had greater odds (adjusted odds ratio, 2.68, 95% confidence interval, 2.09-3.44; P < 0.0001) of returning compared with new patients whose first visit was after the billing change. CONCLUSIONS: Implementation of insurance billing at a publicly funded STD clinic, with free services provided to uninsured individuals, was associated with a modest increase in patient visits and a decline in patients returning for second visits.

RESUMEN

People with HIV (PWH) in Malaysia experience high levels of stigma, which may act as a barrier to accessing healthcare. Stigma against PWH in medical settings is understudied in Malaysia. In the present study, we examine factors associated with physicians' intention to discriminate against PWH in Malaysia. A cross-sectional online survey was emailed to all 1431 physicians at two major university hospitals in Malaysia; 568 (39.6%) participants completed the survey and were included in this analysis. Measures included intention to discriminate against PWH, stigma-related constructs, and socio-demographic characteristics. Multivariate linear regression was used to identify factors associated with intention to discriminate against PWH. Participants were comprised of women (53.5%), Malays (43.1%), and Chinese (35.0%) with nearly 10 years of clinical experience. Most participants were from non-surgical specialties (77.6%). The final multivariate linear regression showed that physicians who expressed greater discriminatory intent against PWH also expressed more negative feelings toward PWH, more HIV-related shame, were more fearful of HIV, and believed that PWH do not deserve good care. Physicians from surgical-based specialties were also significantly more likely to endorse discriminatory intent toward PWH. Stigma and intentions to discriminate against a class of patients, including PWH, can undermine engagement in care, which is central to international HIV prevention and treatment strategies. Interventions that reduce stigma toward PWH among physicians are crucial to ensuring equitable and stigma-free healthcare.

RESUMEN

Young transgender women (YTW) are disproportionately affected by HIV, however, little is known about the factors associated with HIV infection and treatment engagement. We examined correlates of HIV infection and the steps of the HIV treatment cascade, specifically, being aware of their HIV infection, linked to care, on ART, and adherent to ART. We analyzed the baseline data of Project LifeSkills, a randomized control trial of sexually active YTW recruited from Chicago, Illinois and Boston, Massachusetts. We conducted multivariable Poisson regressions to evaluate correlates of HIV infection and the steps of the HIV treatment cascade. Nearly a quarter (24.7%) of YTW were HIV-infected. Among HIV-infected YTW, 86.2% were aware of their HIV status, 72.3% were linked to care, 56.9% were on ART, and 46.2% were adherent to ART. Having avoided healthcare due to cost in the past 12 months and not having a primary care provider were associated with suboptimal engagement in HIV care. Our results suggest that improving linkage and retention in care by addressing financial barriers and improving access to primary care providers could significantly improve health outcomes of YTW as well as reduce forward transmission of HIV.

RESUMEN

Respondent-driven sampling (RDS) peer referral has been proven to be an effective recruitment method for hard-to-reach populations; however, its application in diverse populations is limited. Recruitment occurred in two phases: RDS-only followed by development and implementation of an online social network strategy in combination with RDS peer referral (RDS + SNS). Compared to RDS-only, RDS + SNS reached a sample that was younger (χ(2) = 9.19, P = .03), more likely to identify with a non-binary gender identity (χ(2) = 10.4247, P = .03), with less housing instability (50.5 vs. 68.6 %, χ(2) = 9.0038, P = .002) and less sex work (19.7 vs. 31.4 %, χ(2) = 5.0798, P = .02). Additionally, we describe lessons learned as a result of implementing our online social network strategy. Our findings underscore the importance of integrating Internet-driven strategies to meet challenges in sample diversity and recruitment of young transwomen.

RESUMEN

Men who have sex with men (MSM) living in countries with strong stigma toward MSM are vulnerable to HIV and experience significant barriers to HIV care. Research is needed to inform interventions to reduce stigma toward MSM in these countries, particularly among healthcare providers. A cross-sectional survey of 1158 medical and dental students was conducted at seven Malaysian universities in 2012. Multivariate analyses of variance suggest that students who had interpersonal contact with MSM were less prejudiced toward and had lower intentions to discriminate against MSM. Path analyses with bootstrapping suggest stereotypes and fear mediate associations between contact with prejudice and discrimination. Intervention strategies to reduce MSM stigma among healthcare providers in Malaysia and other countries with strong stigma toward MSM may include facilitating opportunities for direct, in-person or indirect, media-based prosocial contact between medical and dental students with MSM.

RESUMEN

Despite efforts to eliminate it at the societal level, HIV stigma persists and continues to threaten the health of people living with HIV (PLWH). We tested whether social support, adaptive coping, and/or HIV identity centrality act as resilience resources by buffering people from the negative impact of enacted and/or anticipated stigma on stress and ultimately HIV symptoms. Ninety-three PLWH completed a survey, and data analyses tested for evidence of mediation and moderation. Results demonstrated that instrumental social support, perceived community support, and HIV identity centrality buffered participants from the association between anticipated stigma and HIV symptoms. That is, anticipated stigma was associated with HIV symptoms via stress only at low levels of these resources. No resources buffered participants from the impact of enacted stigma. Identifying and enhancing resilience resources among PLWH is critical for protecting PLWH from the harmful effects of stigma.

RESUMEN

Heavy episodic drinking, "binge drinking", is highly prevalent among men who have sex with men (MSM) and is associated with sexual risk behaviors and HIV seroconversion in this population. We characterized the magnitude of binge drinking and explored correlates of increasing levels of binge drinking among MSM in San Francisco. In this study, 67% of MSM reported binge drinking in the prior year. The mean number of drinking days in the past month was 11.6. On average, we estimate that 2,699,372 drinks are consumed by MSM in San Francisco every month. Increasing levels of binge drinking was independently associated with younger age, modest income, being born in the United States, never accessing alcohol treatment and reporting unprotected insertive anal intercourse. Our findings underscore the need to target effective strategies to address heavy alcohol consumption and highlight the urgent need to develop novel interventions beyond traditional alcohol treatment settings among MSM.

RESUMEN

OBJECTIVES: Stigma towards people living with HIV/AIDS (PLWHA) is strong in Malaysia. Although stigma has been understudied, it may be a barrier to treating the approximately 81 000 Malaysian PLWHA. The current study explores correlates of intentions to discriminate against PLWHA among medical and dental students, the future healthcare providers of Malaysia. METHODS: An online, cross-sectional survey of 1296 medical and dental students was conducted in 2012 at seven Malaysian universities; 1165 (89.9%) completed the survey and were analysed. Socio-demographic characteristics, stigma-related constructs and intentions to discriminate against PLWHA were measured. Linear mixed models were conducted, controlling for clustering by university. RESULTS: The final multivariate model demonstrated that students who intended to discriminate more against PLWHA were female, less advanced in their training, and studying dentistry. They further endorsed more negative attitudes towards PLWHA, internalised greater HIV-related shame, reported more HIV-related fear and disagreed more strongly that PLWHA deserve good care. The final model accounted for 38% of the variance in discrimination intent, with 10% accounted for by socio-demographic characteristics and 28% accounted for by stigma-related constructs. CONCLUSIONS: It is critical to reduce stigma among medical and dental students to eliminate intentions to discriminate and achieve equitable care for Malaysian PLWHA. Stigma-reduction interventions should be multipronged, addressing attitudes, internalised shame, fear and perceptions of deservingness of care.

RESUMEN

INTRODUCTION: There is a dearth of studies to quantify the use of illicit fillers by transwomen. Case studies of illicit filler injections have pointed to an array of serious health complications, including death. AIMS: The aims of this study were to determine the population prevalence and identify correlates of filler use among transwomen in San Francisco, CA. METHODS: An analysis of data collected in 2013 with a population-based sample of 233 transwomen recruited using respondent-driven sampling (RDS). We used RDS weights to conduct bivariate and multivariate analyses of correlates of filler use. MAIN OUTCOME MEASURES: Main outcome measures were an RDS-weighted population prevalence of filler use among transwomen and differences in demographic characteristics, transition-related care factors, and self-esteem related to appearance. RESULTS: Weighted filler prevalence among transwomen was 16.7%. Being a transwoman between 30 and 49 years of age, owning/renting or living with a partner/family/friend, having had and planning to have surgery in the future, and having used nonprescribed hormones were all significantly associated with filler use. HIV was not associated with filler use. CONCLUSIONS: This study provides the first known estimate to date of the prevalence of filler use in a population-based sample of transwomen in San Francisco. Accessing illicit fillers may be the only choice available for many transwomen to make changes to their appearance due to the high cost of legal surgeries and other cosmetic procedures. An important next step in this research is to determine the overall prevalence and long-term consequences of filler use among transwomen, to explore how the use of fillers is protective to the safety and well-being of transwomen, and to find safe and affordable alternatives to this method that meet important gender-related appearance needs.

RESUMEN

Stigma perpetuated by health-care providers has been found to be a barrier to care for vulnerable populations, including HIV-infected, people who inject drugs (PWIDs), and men who have sex with men (MSM) in multiple clinical contexts and remains unexamined among professional health-care students in Malaysia. This cross-sectional, anonymous, and Internet-based survey assessed the attitudes of medical and dental students toward HIV-infected, PWID, and MSM patients. Survey invitation was emailed to 3191 students at 8 professional schools; 1296 (40.6%) responded and scored their attitudes toward these patient groups using a feeling thermometer, indicating their attitudes on a sliding scale from 0 (most negative) to 100 (most positive). Compared to general patients (mean = 76.50), the mean scores for HIV-infected (mean = 54.04; p < 0.001), PWID (mean = 37.50; p < 0.001), and MSM (mean = 32.13; p < 0.001) patients were significantly lower and significantly different between each group comparison. Within group differences, most notably religion, ethnicity, and personally knowing someone from these populations were associated with significant differences in attitudes. No differences were noted between pre-clinical and clinical year of training. Health-care students represent the next generation of clinicians who will be responsible for future HIV prevention and treatment efforts. Our findings suggest alarmingly negative attitudes toward these patients, especially MSM, necessitating prompt and effective interventions designed to ameliorate the negative attitudes of health-care students toward vulnerable populations, specifically HIV-infected, PWID, and MSM patients in Malaysia.

RESUMEN

PURPOSE: The evolving epidemiology and treatment landscape of COVID-19 necessitates research into potential drug-drug interactions (pDDIs) from the use of new treatments for COVID-19, particularly those that contain ritonavir, a potent inhibitor of the cytochrome P350 3A4 (CYP3A4) metabolic pathway. In this study, we assessed the prevalence of pDDIs between medications for chronic conditions metabolized through the CYP3A4 metabolic pathway and ritonavir-containing COVID-19 medications in the US general population. METHODS: This study combined National Health and Nutrition Examination Survey (NHANES) waves 2015 to 2016 and 2017 to March 2020 to observe pDDI prevalence between ritonavir-containing therapy and coadministered medications among US adults 18 years or older. CYP3A4-mediated medications were identified from affirmative medication questionnaire response and associated prescription examination by surveyors. CYP3A4-mediated medications with associated pDDIs with ritonavir and assessed pDDI severity (minor, major, moderate, and severe) were obtained from the University of Liverpool's COVID-19 online drug interaction checker, Lexicomp, and US Food and Drug Administration fact sheets. pDDI prevalence and severity were evaluated by demographic characteristics and COVID-19 risk factors. FINDINGS: A total of 15,685 adult participants were identified during the 2015 to 2020 NHANES waves. Survey participants used a mean (SD) of 2.7 (1.8) drugs with likelihood of a pDDI. The weighted prevalence of major to contraindicated pDDIs among the US population was 29.3%. Prevalence rates among those 60 years and older, with serious heart conditions, with moderate chronic kidney disease (CKD), with severe CKD, with diabetes, and with HIV were 60.2%, 80.7%, 73.9%, 69.5%, 63.4%, and 68.5%, respectively. Results remained largely unchanged after removal of statins from the list of drugs associated with ritonavir-based pDDIs. IMPLICATIONS: Approximately one-third of the US population would be at risk for a major or contraindicated pDDI should they receive a ritonavir-containing regimen, and this risk increases significantly among individuals 60 years or older and with comorbidities such as serious heart conditions, CKD, diabetes, and HIV. The state of polypharmacy in the US population and the quickly changing COVID-19 landscape indicate significant risk of pDDIs among those requiring treatment with ritonavir-containing COVID-19 medications. Practitioners should take polypharmacy, age, and comorbidity profile into account when prescribing COVID-19 therapies. Alternative treatment regimens should be considered, especially for those of older age and those with risk factors for progression to severe COVID-19.

RESUMEN

BACKGROUND: The use and potential benefit of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) monoclonal antibodies (mAbs) for the treatment of mild-to-moderate coronavirus disease 2019 (COVID-19) in people living with multiple sclerosis (pwMS) remains poorly studied. The objective of this study is to describe the therapeutic use of anti-SARS-CoV-2 mAbs among pwMS. METHODS: This retrospective cohort study used electronic medical records data from the TriNetX Dataworks USA Network and included adult pwMS, diagnosed with COVID-19, who received anti-SARS-CoV-2 mAbs in the outpatient setting between November 2020 and April 2022. We analyzed COVID-19 severity at anti-SARS-CoV-2 mAb initiation and up to 30 days, stratified by before/after emergence of Omicron variant and by disease-modifying therapy (DMT). RESULTS: The study included 434 pwMS treated with anti-SARS-CoV-2 mAbs for mild-to-moderate COVID-19, including 270 patients before and 174 after Omicron emergence. Most pwMS were female (80.2%), mean age (SD) was 51.5 (12.5) years. Two-hundred-and-five patients were on DMTs, 51% of whom received anti-CD20s. One patient with moderate COVID-19 was hospitalized whilst receiving glatiramer acetate. No patients required intensive care and there were no deaths. COVID-19 outcomes were comparable following anti-SARS-CoV-2 mAb therapy in patients receiving different DMTs. CONCLUSION: Anti-SARS-CoV-2 mAb treatment for pwMS with mild-to-moderate COVID-19 may reduce the risk of COVID-19-related hospitalization and death.

RESUMEN

Despite increasingly stringent requirements from regulatory agencies, clinical trials often fail to recruit study populations representative of real-world demographics and disease prevalence and are often skewed away from racial/ethnic minorities. Consequently, data produced by such trials can result in treatment guidelines and outcome expectations that do not apply to racial/ethnic minorities, further widening health disparities. In this study, we describe a new tool, the TriNetX Diversity Lens ("Diversity Lens"), which augments the existing electronic health record querying functionality of TriNetX and allows clinical trial sponsors to rapidly evaluate the potential impact of inclusion and exclusion criteria on the eligibility rates of different racial and ethnic groups. We describe the development of Diversity Lens in collaboration with public and private stakeholders. Additionally, we feature examples of how Diversity Lens can bring to the surface insights into existing health disparities and prospectively explore the impact of study criteria on the eligibility of racial/ethnic minorities.

RESUMEN

PURPOSE: To examine how recent sex work is identified and the HIV risk factors and service needs among Thai cisgender men who have sex with men (MSM) and transgender women (TGW) who exchange sex. METHODS: MSM and TGW in Bangkok and Pattaya who exchanged sex in the last year (n = 890) were recruited through social media, outreach, and word-of-mouth. Recent sex exchange was based on the primary question, "In the last 30 days, have you sold or traded sex"; secondary questions (regarding income source and client encounters) were also investigated. RESULTS: Overall, 436 (48%) participants engaged in sex work in the last 30 days; among those, 270 (62%) reported exchanging sex by the primary question, and 160 (37%) based on secondary questions only. Recent sex exchange was associated with gonorrhea, syphilis, discussing PrEP with others, and using condoms, alcohol, methamphetamine, amyl nitrate, and Viagra. Exchanging sex based on secondary questions only was associated with being in a relationship, social media recruitment, less recent anal intercourse, and not discussing PrEP. CONCLUSIONS: Thai MSM and TGW who exchange sex need regular access to HIV/STI prevention, testing, and treatment services, and multiple approaches to assessing sex work will help identify and serve this diverse and dynamic population.
