HIV testing and counselling is the first crucial step for linkage to HIV treatment and prevention. However, despite high HIV burden in sub-Saharan Africa, testing coverage is low, particularly among young adults and men. Community-based HIV testing and counselling (testing outside of health facilities) has the potential to reduce coverage gaps, but the relative impact of different modalities is not well assessed. We conducted a systematic review of HIV testing and counselling modalities, characterizing facility and community (home, mobile, index, key populations, campaign, workplace and self-testing) approaches by population reached, HIV-positivity, CD4 count at diagnosis and linkage. Of 2,520 abstracts screened, 126 met eligibility criteria. Community HIV testing had high coverage and uptake and identified HIV-positive individuals at higher CD4 counts than facility testing. Mobile HIV testing reached the highest proportion of men of all modalities examined (50%, 95% CI = 47–54%) and home with self-testing reached the highest proportion of young adults (66%, 95% CI = 65–67%). Few studies evaluated HIV testing and counselling for key populations (commercial sex workers and men who have sex with men), but these interventions yielded high HIV positivity (38%, 95% CI = 19–62%) combined with the highest proportion of first-time testers (78%, 95% CI = 63–88%), indicating service gaps. Facilitated linkage (for example, counsellor follow-up to support linkage) achieved high linkage to care (95%, 95% CI = 87–98%) and ART initiation (75%, 95% CI = 68–82%). Expanding mobile HIV testing, self-testing and outreach to key populations with facilitated linkage can increase the proportion of men, young adults and high-risk individuals linked to HIV treatment and prevention.

HIV-positive women have higher risk of acquiring HPV, with risk inversely associated with CD4 cell count. ART lowered HPV acquisition, increased clearance, and reduced precancer progression, likely via immune reconstitution. Although some of our results are limited by small number of studies, our study can inform screening guidelines and mathematical modeling for cervical cancer prevention.

Background The COVID-19 pandemic has severely impacted Intensive Care Units (ICUs) and Critical Care Healthcare Providers (HCPs) worldwide. Research Question How do regional differences and perceived lack of ICU resources affect critical care resource utilization and the well-being of HCPs? Study Design and Methods Between April 23 rd -May 7 th 2020, we electronically administered a 41-question survey to interdisciplinary HCPs caring for critically ill COVID-19 patients. The survey was distributed via critical care societies, research networks, personal contacts, and social media portals. Responses were tabulated by World Bank region. We performed multivariate log-binomial regression to assess factors associated with three main outcomes: 1) Limiting mechanical ventilation (MV), 2) changes in cardiopulmonary resuscitation (CPR) practices, and 3) emotional distress or burnout. Results We included 2700 respondents from 77 countries, including physicians (41%), nurses (40%), respiratory therapists (10%) and advanced practice providers (8%). The reported lack of ICU nurses was higher than that of intensivists (32% vs 15%). Limiting MV for COVID-19 patients was reported by 16% of respondents, was lowest in North America (10%), and was associated with reduced ventilator availability (aRR:2.10, 95% CI:1.61-2.74). Overall, 66% of respondents reported changes in CPR practices. Emotional distress or burnout was high across regions (52%, highest in North America), and associated with female gender (aRR:1.16, 95% CI:1.01-1.33), being a nurse (aRR:1.31, 95% CI:1.13-1.53), reporting a shortage of ICU nurses (aRR:1.18, 95% CI:1.05-1.33) and powered air-purifying respirators (PAPRs) (aRR:1.30 95% CI:1.09-1.55), as well as experiencing poor communication from supervisors (aRR:1.30, 95% CI:1.16-1.46). Interpretation Our findings demonstrate variability in ICU resource availability and utilization worldwide. The high prevalence of provider burnout, and its association with reported insufficient resources and poor communication from supervisors suggest a need for targeted interventions to support HCPs on the front lines.

Mathematical models of cervical cancer have been widely used to evaluate the comparative effectiveness and cost-effectiveness of preventive strategies. Major advances in the understanding of cervical carcinogenesis motivate the creation of a new disease paradigm in such models. To keep pace with the most recent evidence, we updated a previously developed microsimulation model of human papillomavirus (HPV) infection and cervical cancer to reflect 1) a shift towards health states based on HPV rather than poorly reproducible histological diagnoses and 2) HPV clearance and progression to precancer as a function of infection duration and genotype, as derived from the control arm of the Costa Rica Vaccine Trial (2004-2010). The model was calibrated leveraging empirical data from the New Mexico Surveillance, Epidemiology, and End Results Registry (1980-1999) and a state-of-the-art cervical cancer screening registry in New Mexico (2007-2009). The calibrated model had good correspondence with data on genotype- and age-specific HPV prevalence, genotype frequency in precancer and cancer, and age-specific cancer incidence. We present this model in response to a call for new natural history models of cervical cancer intended for decision analysis and economic evaluation at a time when global cervical cancer prevention policy continues to evolve and evidence of the long-term health effects of cervical interventions remains critical.

Background Assessing the impact of COVID-19 on intensive care unit (ICU) providers’ perceptions of resource availability and evaluating factors associated with emotional distress/burnout can inform interventions to promote provider well-being. Methods Between April 23-May 7, 2020, we electronically administered a survey to physicians, nurses, respiratory therapist (RTs) and advanced practice providers (APPs) caring for COVID-19 patients in the US. We conducted multivariate regression to assess associations between concerns, reported lack of resources and three outcomes: emotional distress/burnout (primary outcome), and two secondary outcomes: 1) fear that hospital is unable to keep providers safe, and 2) concern about transmitting COVID-19 to family/community. Results We included 1,651 respondents from all 50 states; 47% nurses, 25% physicians, 17% RTs, 11% APPS. Shortages of intensivists and ICU nurses were reported by 12% and 28% of providers, respectively. The largest supply restrictions reported were for powered air purifying respirators (PAPRs); (56% reporting restricted availability). Provider concerns included worries about transmitting COVID-19 to family/community (66%), emotional distress/burnout (58%), and insufficient personal protective equipment (PPE) (40%). After adjustment, emotional distress/burnout was significantly associated with insufficient PPE access (aRR: 1.43, 95% CI: 1.32 - 1.55), stigma from community (aRR: 1.32, 95% CI: 1.24 - 1.41), and poor communication with supervisors (aRR:1.13, 95% CI: 1.06 - 1.21). Insufficient PPE access was the strongest predictor of feeling that the hospital is unable to keep providers safe and worries about transmitting infection to families/communities. Conclusion Addressing insufficient PPE access, poor communication from supervisors, and community stigma may improve provider mental well-being during the COVID-19 pandemic.
