Pregnancy and STI/HIV prevention intervention preferences of South African adolescent girls: findings from a cultural consensus modelling qualitative study.

South African adolescent girls experience high rates of unintended pregnancy and sexually transmitted infections including HIV. To inform culturally-tailored dual protection interventions to prevent both unintended pregnancy and STIs/HIV, this study qualitatively examined girls' sexual health intervention preferences. Participants were aged 14-17 years old and Sesotho-speaking (N = 25). To elucidate shared cultural beliefs, individual interviews examined participants' perceptions about other adolescent girls' pregnancy and STI/HIV prevention intervention preferences. Interviews were conducted in Sesotho and translated into English. Two independent coders identified key themes in the data using a conventional content analysis approach with discrepancies resolved by a third coder. Participants indicated that intervention content should include efficacious pregnancy and STI/HIV prevention methods and ways to navigate peer pressure. Interventions should be accessible, avoid criticism and provide high-quality information. Preferred intervention formats included online, SMS/text, or delivery by social workers or older, knowledgeable peers, with mixed acceptability for delivery by parents or same-age peers. Schools, youth centres and sexual health clinics were preferred intervention settings. Results highlight the importance of cultural context in tailoring dual protection interventions to address the reproductive health disparities among adolescent girls in South Africa.

Integrating long-acting injectable treatment to improve medication adherence among persons living with HIV and opioid use disorder: study protocol.

BACKGROUND: Oral antiretroviral therapy (ART) has been effective at reducing mortality rates of people with HIV. However, despite its effectiveness, people who use drugs face barriers to maintaining ART adherence. Receipt of opioid agonist treatment, in the context of HIV care, is associated with medication adherence and decreased HIV viral loads. Recent pharmacological advancements have led to the development of novel long-acting, injectable, medications for both HIV (cabotegravir co-administered with rilpivirine) and OUD (extended-release buprenorphine). These therapies have the potential to dramatically improve adherence by eliminating the need for daily pill-taking. Despite the extensive evidence base supporting long-acting injectable medications for both HIV and OUD, and clinical guidelines supporting integrated care provision, currently little is known about how these medications may be optimally delivered to this population. This paper presents the study design for the development of a clinical protocol to guide the delivery of combined treatment for HIV and OUD using long-acting injectable medications. METHODS: The study aims are to: (1) develop a clinical protocol to guide the delivery of combined LAI for HIV and OUD by conducting in-depth interviews with prospective patients, clinical content experts, and other key stakeholders; and (2) conduct This single group, open pilot trial protocol to assess feasibility, acceptability, and safety among patients diagnosed with HIV and OUD. Throughout all phases of the study, information on patient-, provider-, and organizational-level variables will be collected to inform future implementation. DISCUSSION: Findings from this study will inform the development of a future study to conduct a fully-powered Hybrid Type 1 Effectiveness-Implementation design.

Concordance of Ethyl Glucuronide, Blood Alcohol Content, and Self-Reported Alcohol Use in Russian Women with HIV and Hepatitis C Virus Co-Infection.

Problematic alcohol use is prevalent in Russia and is deleterious for individuals with HIV and Hepatitis C Virus (HCV). Ethyl glucuronide (EtG) and blood alcohol content (BAC) provide objective biomarkers of drinking that can be compared to self-reported alcohol use. This paper describes patterns of alcohol use measured by biomarkers and self-report along with concordance across measures. Participants were Russian women with HIV and HCV co-infection (N = 200; Mean age = 34.9) from two Saint Petersburg comprehensive HIV care centers enrolled in an alcohol reduction intervention clinical trial. Measures were: (a) urine specimen analyzed for EtG; (b) breathalyzer reading of BAC; and (c) self-reported frequency of drinking, typical number of drinks consumed, and number of standard drinks consumed in the past month. At baseline, 64.0% (n = 128) had a positive EtG (> 500 ng/mL) and 76.5% (n = 153) had a positive breathalyzer reading (non-zero reading). There was agreement between EtG and BAC (kappa = 0.66, p < .001; Phi coefficient = 0.69, p < .001); self-reported alcohol measures were positively correlated with positive EtG and BAC (p's < 0.001). There was concordance between EtG and BAC measures, which have differing alcohol detection windows. Most participants endorsed frequent drinking at high quantities, with very few reporting no alcohol consumption in the past month. Concordance between biomarkers and self-reported alcohol use suggests that underreporting of alcohol use was minimal. Results highlight the need for alcohol screening within HIV care. Implications for alcohol assessment within research and clinical contexts are discussed.

Interpersonal abuse and alcohol use among African American young women: the mediating role of emotion dysregulation.

African American women experience a high prevalence of alcohol-related consequences, and no studies have explicitly examined the associations among lifetime interpersonal abuse, emotion dysregulation, and alcohol-related outcomes during the critical period of young adulthood within this population. This study used baseline data from a sample of African American young women (N = 560) who use alcohol, aged 18 to 24, enrolled in an HIV prevention intervention trial to examine whether emotion dysregulation mediated the relation between lifetime history of abuse and problematic alcohol use. Further, we sought to examine whether there were potential differential levels of problematic alcohol use based on the number of abuse types experienced. Multiple regression analyses showed that exposure to two or more forms of abuse was associated with problematic alcohol use, ß = .24, p < .001, and heavy alcohol consumption, ß = .23, p < .001, whereas history of a single form was not. Indirect effects of both single and multiple forms of abuse on problematic alcohol use (95% confidence interval [CI] [.16, 1.02]; [.46, 1.64]) and heavy alcohol consumption (95% CI [.02, .26]; [.05, .45]) via emotion dysregulation severity were found. Abuse and emotion dysregulation were associated with frequency of alcohol use and binge drinking, but not typical amount consumed. Hazardous alcohol consumption was prevalent among this sample of African American young women who use alcohol. This study provides preliminary evidence that emotion dysregulation may be an important mechanism buttressing the association between lifetime history of interpersonal abuse and problematic alcohol use among African American young women who use alcohol.

Development and Cultural Adaptation of a Computer-Delivered and Multi-Component Alcohol Reduction Intervention for Russian Women Living with HIV and HCV.

BACKGROUND: There is elevated prevalence of problem drinking among Russian women living with HIV and HCV co-infection. This paper describes the development and cultural adaptation of a multi-component alcohol reduction intervention incorporating a brief, computer-delivered module for Russian women living with HIV and HCV co-infection. METHODS: The format and content of the intervention were adapted to be linguistic-, cultural-, and gender-appropriate using the ADAPT-ITT framework. A computer-delivered module and brief clinician-delivered individual and telephone sessions were developed. RESULTS: We describe the theoretical foundations of the intervention, the cultural adaptation of the intervention, and overview the content of the intervention's multiple components. DISCUSSION: Interventions to reduce alcohol use that can be integrated within Russian HIV treatment centers are urgently needed. If efficacious, the culturally-adapted intervention offers the promise of a cost-effective, easily disseminated intervention approach for Russian women living with HIV/HCV co-infection engaging in problematic alcohol use.

Substance Use Screening in HIV Care Settings: a Review and Critique of the Literature.

PURPOSE OF REVIEW: People living with human immunodeficiency virus/AIDS (PLWHA) experience high prevalence of substance use disorders (SUD). HIV care settings represent a unique opportunity to identify possible SUD, to provide SUD interventions, and to improve linkage to SUD treatment. The aims of this paper are to (a) review and critique the extant literature examining substance use screening approaches among PLWHA in HIV care settings and (b) provide recommendations for future clinical practice. RECENT FINDINGS: Twenty-one peer-reviewed articles that examined substance screening approaches employed in HIV and other primary care settings were included in the review. There was limited literature reporting on the implementation and evaluation of substance use screening practices within HIV care settings, and methodological rigor varied across studies. Further, the use of validated substance use screening measures or incorporation of other substance use screening approaches (e.g., use of urine drug testing) within routine HIV care practice is limited. Strategies to implement routine substance use screening within HIV care and incorporate additional substance use assessment, brief interventions, and referral to specialty substance use treatment are discussed. Use of self-report substance use screening measures using web- or computer-delivered approaches that can be integrated within electronic health record systems is particularly promising. HIV care practices should consider potential models to optimally screen and treat SUD. Co-location of HIV and SUD treatment services may be optimal; when co-located services are not possible, strategies to consistently provide brief intervention approaches and referrals to specialty SUD treatment are needed.

The effect of fenoldopam and dopexamine on hepatic blood flow and hepatic function following coronary artery bypass grafting with hypothermic cardiopulmonary bypass.

BACKGROUND: Hypothermic cardiopulmonary bypass is associated with low perfusion state causing a mismatch between demand and supply to various organs such as gut, kidneys and brain. The consequences are thought to be responsible for postoperative complications like systemic inflammatory response, renal failure, neurological injury, etc. Pharmacological agents like dopamine, dopexamine and dobutamine have been used in an attempt to reduce hypoperfusion and hence complications. Fenoldopam, a dopamine analog (DA-1 receptor agonist), has recently been shown to be specific reno-splanchnic vasodilator in animal studies. We studied the haemodynamic effects of fenoldopam and its effect on hepatic blood flow (HBF) during and after cardiopulmonary bypass and compared these with dopexamine. METHODS: Ethics committee approval was obtained. Forty-two consecutive patients with good/moderate left ventricular function undergoing either elective/urgent coronary artery bypass grafting were included in the study. Patients were randomised to receive either fenoldopam (0.2 microg/kgmin) (F; n=14) or dopexamine (2.0 microg/kgmin) (Dx; n=14) normal saline (NS; n=14) continuously after induction of anaesthesia for 24h following completion of surgery. HBF was measured using the Indocyanine green dye disappearance rate method, before, during and after cardiopulmonary bypass. Data were collected pre-, intra- and postoperatively. Serum liver enzymes were measured during the perioperative period. Repeated measures ANOVA test was used to compare timed samples in both groups. RESULTS: The study groups were comparable in pre- and intraoperative variables. In the fenoldopam and dopexamine groups there was a significant increase in heart rate 15 min following the commencement of the infusion (NS:F:DX::-2.0+/-7.8 beats/min:13.6+/-8.1 beats/min (p=0.007):18.36+/-20.2 beats/min (p=0.004)). However the change in mean arterial blood pressure was similar (NS:F:DX::-12.7+/-14.9:-4.0+/-23.1 (p=0.699):-2.6+/-22.3) (p=0.235). Cardiac index increased and systemic vascular resistance decreased (requiring noradrenaline infusion) in the fenoldopam group, however this did not reach statistical significance. Hepatic blood flow reduced during CPB and returned to near preoperative levels in all three groups with no statistical difference between groups. CONCLUSIONS: Fenoldopam infusion induced transient tachycardia, with no augmentation of hepatic blood flow whereas dopexamine induced tachycardia and did not augment hepatic blood flow. Fenoldopam and dopexamine may have hepato-protective effect.

Serum epidermal growth factor receptor and HER2 expression in primary and metastatic breast cancer patients.

BACKGROUND: Breast tissue expression of the ERBB proto-oncogene family has been extensively studied. It was recently shown that expression of epidermal growth factor receptor (EGFR; c-erbB-1) and epidermal growth factor receptor (HER)2 (c-erbB-2) can be detected in the serum of breast cancer patients. The clinical relevance of this has not been fully established. METHODS: EGFR and HER2 immunoassays were conducted in blood from 57 patients in whom paired serum samples were available (from the times of primary and metastatic diagnoses), from 96 primary breast cancer patients and from 49 normal individuals. Of the 57 patients with paired serum samples, paired tissue samples for HER2 expression were available for eight. RESULTS: Serum levels of EGFR serum levels were significantly higher in normal individuals (median 75.3 ng/ml, range 43.2 to 114.2 ng/ml) than in patients with primary breast cancer (median 59.3 ng/ml, range 21.3 to 94.1 ng/ml; P < 0.001). In the paired serum samples, EGFR levels decreased significantly between the time of primary diagnosis (median 56.3 ng/ml, range 29.1 to 142.7 ng/ml) and metastatic diagnosis (median 30.9 ng/ml, range 10.9 to 106.4 ng/ml; P < 0.001). In six (11%) a change occurred from over-expression (>78 ng/ml) to normal expression. In contrast, no significant difference was seen in HER2 serum levels in normal individuals (median 12.2 ng/ml, range 7.8 to 20.9 ng/ml) and primary breast cancer patients (median 12.5 ng/ml, range 6.9 to 122.2 ng/ml; P = 0.511). However, in the paired serum samples, HER2 levels increased significantly between the time of primary (median 12.2 ng/ml, range 5.7 to 85.0 ng/ml) and metastasis (median 17.7 ng/ml, range 6.3 to 3,337.4 ng/ml; P < 0.001). HER2 over-expression (>15 ng/ml) was observed in 16 out of 57 patients (28%) at primary breast cancer diagnosis and in 31 out of 57 (54%) at metastasis. In 18 patients (32%) HER2 expression changed from normal to over-expression. CONCLUSION: Decisions regarding the use of targeted therapies in the metastatic setting are often based on the oncogene expression of the primary tumour. Our results suggest that serum oncogene assessments may be complementary to this and could potentially widen the indications for these beneficial therapies.
