Introduction: Coronavirus disease 2019 (COVID-19) has impacted researchers' ability to continue to deliver HIV prevention and treatment interventions face to face. Although telehealth has been an important strategy to maintain research operations during the current pandemic, participants at increased risk of or living with HIV are often at higher risk of also experiencing poverty, housing instability, and other challenges that may present obstacles to successful remote delivery. Methods: We provide descriptions of remote adaptations to two randomized controlled efficacy trials of behavioral interventions for primary and secondary HIV prevention with descriptive enrollment and retention data. Results and Conclusions: Best practices for implementing telemedicine and e-health procedures are discussed, including procedures for addressing remote participation barriers (economic, health literacy, etc.) and other challenges, such as building rapport and staff support (NCT03092531 and NCT03175159).

OBJECTIVES: Acceptance and Commitment Therapy (ACT) is a third-wave behavioral and cognitive therapy that increases psychological flexibility through mindfulness, acceptance, and value-driven behavior change. ACT has been successfully used to inform a variety of health interventions. Using non-therapists to deliver ACT-based behavioral health interventions offers an opportunity to provide cost efficient and integrated care, particularly among underserved populations experiencing barriers to mental health care, such as inadequate insurance, mental health stigma, and provider shortages. This systematic review aims to: 1) identify ACT-informed behavioral health interventions delivered by laypeople and 2) review the specific characteristics of each intervention including number and duration of sessions, delivery modality, interventionist training, and intervention outcomes. METHODS: Two databases (PubMed and PsycINFO) were systematically searched for relevant literature. To further identify relevant studies, references of included manuscripts were checked, the Association for Contextual Behavioral Science’s webpage was examined, and an email was sent to the ACBS Health Special Interest Group listserv. Study abstracts and full texts (in English) were screened, resulting in 23 eligible articles describing 19 different interventions. RESULTS: A total of 1,781 abstracts were screened, 76 were eligible for full-text review, and 23 were included in a narrative synthesis. There were 19 unique interventions identified and delivered by the following: general healthcare workers (n= 7), trained researchers (n = 5), women/mothers (n= 2), municipal workers (n= 2), and teachers (n = 3). Eleven studies were RCTs and eight utilized alternative study designs. Study quality varied, with two rated as high risk for bias and eight rated to have some concerns. Target populations included clinical and non-clinical samples. There was some consistency in the effects reported in the studies: increases in pain tolerance, acceptance, and identifying and engaging in value driven behavior, improvements in cognitive flexibility, and reductions in psychological distress. CONCLUSIONS: Findings suggest that ACT interventions can be successfully delivered by a variety of laypeople and effectively address psychological distress and increase health behaviors.

Decarbazine is an imidazole dimethyltriazene with reproducible activity in patients with metastatic melanoma. CB10-277 is a phenyl dimethyltriazene which, like dacarbazine, requires metabolic activation to its corresponding monomethyl species for antitumour activity. In preclinical models (human melanoma xenografts and transplantable rodent tumours) CB10-277 showed a similar spectrum and level of activity when compared to dacarbazine. Pharmacokinetic studies were performed with CB10-277 in mice treated i.v. at the LD10 (750 mg m-2) and plasma analysed by HPLC. The parent drug area under the plasma concentration vs time curve (AUC) was 142 mM x minutes. Drug metabolism occurred as evidenced by the HPLC identification of the monomethyl species (AUC = 8 mM x minutes) as well as other metabolites. A Phase I trial using a short infusion with doses repeated every 21 days has been performed. Thirty-six patients received 80 courses over a dose range of 80-6,000 mg m-2. The dose limiting toxicity was nausea and vomiting which occurred in 80% of the evaluable courses > or = 900 mg m-2. The only other common side effect was a flushing or warm sensation, which occurred in over 75% of courses at > or = 1,350 mg m-2. There were no hemodynamic consequences. Responses occurred in patients with melanoma (one complete, two partial, one mixed/11), sarcoma (one mixed/6) and carcinoid (one partial/l). Pharmacokinetics were performed in 46 courses. The CB10-277 AUC increased linearly with dose (r = 0.9203, P < 0.001) up to 700 mM x minutes at 6,000 mg m-2). Evidence of CB10-277 metabolism was observed, as in mice, by detection of the monomethyl species and other metabolites. However, the plasma levels of the monomethyl species in patients (1.8 and 3.7 mM x minutes at 6,000 mg m-2) were less than those predicted from studies in mice. Despite this, antitumour activity in dacarbazine sensitive histologies was observed and additional studies with CB10-277 are recommended.

Integrated antibiotic resistance (AR) surveillance is one of the objectives of the World Health Organization global action plan on antimicrobial resistance. Urban wastewater treatment plants (UWTPs) are among the most important receptors and sources of environmental AR. On the basis of the consistent observation of an increasing north-to-south clinical AR prevalence in Europe, this study compared the influent and final effluent of 12 UWTPs located in seven countries (Portugal, Spain, Ireland, Cyprus, Germany, Finland, and Norway). Using highly parallel quantitative polymerase chain reaction, we analyzed 229 resistance genes and 25 mobile genetic elements. This first trans-Europe surveillance showed that UWTP AR profiles mirror the AR gradient observed in clinics. Antibiotic use, environmental temperature, and UWTP size were important factors related with resistance persistence and spread in the environment. These results highlight the need to implement regular surveillance and control measures, which may need to be appropriate for the geographic regions.
