Developing Leaders in Surgical Residency: A Curriculum for Success.

OBJECTIVE: As surgical residents continue in their training, they are expected to not only take part in more complicated procedures, but to also serve as leaders in their respective care teams. While surgical skills are intensively taught in surgical residency programs, leadership is often learned informally, to the detriment of residents. Our curriculum was developed and implemented to provide foundational knowledge for surgical residents as they take on senior roles so that they may successfully act as leaders. This educational workshop was effective and efficient and can be applied at other residency programs that seek to improve the leadership skills of their residents. DESIGN: Implementation of a 3-day program focused on leadership, surgical skills, and career development to provide rising PGY-4 surgical residents with the abilities necessary for successful training. SETTING: This program was implemented at the University of Minnesota General Surgery residency program. PARTICIPANTS: Rising PGY-4 general surgery residents. RESULTS: The program consisted of a 3-day workshop which all rising PGY-4 residents participating in before transitioning into their respective roles. The program was led by the general surgery faculty. CONCLUSIONS: Curricula focused on developing leadership skills in residents can be effectively applied in a time-efficient manner that can benefit the residents as they move into official leadership roles on the care team.

Maternal hepatitis C virus infection and three adverse maternal outcomes in the United States.

BACKGROUND: Hepatitis Virus C (HCV) infection rates have trended upwards among pregnant people in the USA since 2009. Existing evidence about HCV infections and maternal outcomes is limited; therefore, we used birth certificate data to investigate the association between HCV infection and maternal health outcomes. METHODS: We used the 2017 US birth certificate dataset (a cross-section of 1.4 million birth records) to assess the association between prevalent HCV infection and gestational diabetes, gestational hypertension, and eclampsia. Potential confounding variables included prenatal care, age, education, smoking, presence of sexually transmitted infections (STIs), body mass index (BMI), and weight gain during pregnancy. We restricted our analysis to only women with a first singleton pregnancy. Odds ratios were estimated by logistic regression models and separate models were tested for white and Black women. RESULTS: Only 0.31% of the women in our sample were infected with HCV (n = 4412). In an unadjusted model, we observed a modest significant protective association between HCV infection and gestational diabetes (Odds ratio [OR]: 0.83; 95% CI: 0.76-0.96); but this was attenuated with adjustment for confounding variables (Adjusted odds ratio [AOR]: 0.88; 95% CI: 0.76, 1.02). There was no association between HCV and gestational hypertension (AOR: 1.03; 95% CI: 0.91, 1.16) or eclampsia (AOR: 1.15; 95% CI: 0.69, 1.93). Results from the race stratified models were similar to the non-stratified summary models. CONCLUSION: We observed no statistically significant associations between maternal HCV infection with maternal health outcomes. Although, our analysis did indicate that HCV may lower the risk of gestational diabetes, this may be attributable to confounding. Studies utilizing more accurately measured HCV infection including those collecting type and timing of testing, and timing of infection are warranted to ensure HCV does not adversely impact maternal and/or fetal health. Particularly in the absence of recommended therapy for HCV during pregnancy.

Maternal Hepatitis C Virus Infection and Adverse Newborn Outcomes in the US.

OBJECTIVES: We investigated the relationship between maternal hepatitis C virus (HCV) infection and infant health. Furthermore, we evaluated racial disparities with these associations. METHODS: Using 2017 US birth certificate data, we investigated the association between maternal HCV infection and infant birthweight, preterm birth, and Apgar score. We used unadjusted and adjusted linear regression and logistic regression models. Models were adjusted for use of prenatal care, maternal age, maternal education, maternal smoking status, and the presence of other sexually transmitted infections. We stratified the models by race to describe the experiences of White and Black women separately. RESULTS: Maternal HCV infection was associated with reduced infant birthweight on average by 42.0 g (95% CI: -58.81, -25.30) for women of all races, 64.6 g (95% CI: -81.91, -47.26) for White women and 80.3 g (95% CI: -162.48, 1.93) for Black women. Women with maternal HCV infection had increased odds of having a preterm birth of 1.06 (95% CI: 0.96, 1.17) for women of all races, 1.06 (95% CI: 0.96, 1.18) for White women and 1.35 (95% CI: 0.93, 1.97) for Black women. Overall, women with maternal HCV infection had increased odds 1.26 (95% CI: 1.03, 1.55) of having a low/intermediate Apgar score; White and Black women with HCV infection had similarly increased odds of an infant with low/intermediate Apgar score in a stratified analysis: 1.23 (95% CI: 0.98, 1.53) for White women and 1.24 (95% CI: 0.51, 3.02) for Black women. CONCLUSIONS: Maternal HCV infection was associated with lower infant birthweight and higher odds of having a low/intermediate Apgar score. Given the potential for residual confounding, these results should be interpreted with caution.

Causes and risk factors of death among people who inject drugs in Indonesia, Ukraine and Vietnam: findings from HPTN 074 randomized trial.

INTRODUCTION: The HIV Prevention Trials Network (HPTN) 074 study demonstrated a positive effect of an integrated systems navigation and psychosocial counseling intervention on HIV treatment initiation, viral suppression, medication assisted treatment (MAT) enrollment, and risk of death among people who inject drugs (PWID). In this sub-study, we analyzed the incidence, causes, and predictors of death among HIV-infected and uninfected participants. METHODS: The HPTN 074 randomized clinical trial was conducted in Indonesia, Ukraine, and Vietnam. HIV-infected PWID with unsuppressed viral load (indexes) were recruited together with at least one of their HIV-negative injection partners. Indexes were randomized in a 1:3 ratio to the intervention or standard of care. RESULTS: The trial enrolled 502 index and 806 partner participants. Overall, 13% (66/502) of indexes and 3% (19/806) of partners died during follow-up (crude mortality rates 10.4 [95% CI 8.1-13.3] and 2.1 [1.3-3.3], respectively). These mortality rates were for indexes nearly 30 times and for partners 6 times higher than expected in a population of the same country, age, and gender (standardized mortality ratios 30.7 [23.7-39.0] and 5.8 [3.5-9.1], respectively). HIV-related causes, including a recent CD4 < 200 cells/µL, accounted for 50% of deaths among indexes. Among partners, medical conditions were the most common cause of death (47%). In the multivariable Cox model, the mortality among indexes was associated with sex (male versus female aHR = 4.2 [1.5-17.9]), CD4 count (≥ 200 versus < 200 cells/µL aHR = 0.3 [0.2-0.5]), depression (moderate-to-severe versus no/mild aHR = 2.6 [1.2-5.0]) and study arm (intervention versus control aHR = 0.4 [0.2-0.9]). Among partners, the study arm of the index remained the only significant predictor (intervention versus control aHR = 0.2 [0.0-0.9]) while controlling for the effect of MAT (never versus ever receiving MAT aHR = 2.4 [0.9-7.4]). CONCLUSIONS: The results confirm that both HIV-infected and uninfected PWID remain at a starkly elevated risk of death compared to general population. Mortality related to HIV and other causes can be significantly reduced by scaling-up ART and MAT. Access to these life-saving treatments can be effectively improved by flexible integrated interventions, such as the one developed and tested in HPTN 074.

Multiple Infection and Human Immunodeficiency Virus Superinfection Among Persons who Inject Drugs in Indonesia and Ukraine.

BACKGROUND: The HIV Prevention Trials Network (HPTN) 074 study evaluated an integrated human immunodeficiency virus (HIV) treatment and prevention strategy among persons who inject drugs (PWID) in Indonesia, Ukraine, and Vietnam. We previously detected multiple HIV infection in 3 of 7 (43%) of seroconverters with 3-8 HIV strains per person. In this report, we analyzed multiple HIV infection and HIV superinfection (SI) in the HPTN 074 cohort. METHODS: We analyzed samples from 70 participants in Indonesia and Ukraine who had viral load >400 copies/mL at enrollment and the final study visit (median follow-up, 2.5 years). HIV was characterized with Sanger sequencing, next-generation sequencing, and phylogenetic analysis. Additional methods were used to characterize a rare case of triple-variant SI. RESULTS: At enrollment, multiple infection was detected in only 3 of 58 (5.2%) participants with env sequence data. SI was detected in only 1 of 70 participants over 172.3 person-years of follow-up (SI incidence, 0.58/100 person-years [95% confidence interval, .015-3.2]). The SI case involved acquisition of 3 HIV strains with rapid selection of a strain with a single pol region cluster. CONCLUSIONS: These data from a large cohort of PWID suggest that intrahost viral selection and other factors may lead to underestimation of the frequency of multiple HIV infection and SI events.

Patient and Caregiver Perspectives on an eHealth Tool: A Qualitative Investigation of Preferred Formats, Features and Characteristics of a Presurgical eHealth Education Module.

INTRODUCTION: Total hip and total knee replacement (THR and TKR) are suggested for reducing joint pain resulting from hip and knee osteoarthritis (OA), especially when other interventions have not resulted in desired outcomes. Providing prehabilitation education can improve patients' psychological and physical well-being before and after surgery. The use of electronic health (eHealth) tools can be considered an effective method to increase patients' access to prehabilitation, particularly for those facing barriers to attending diagnosis-specific in-person education sessions. However, limited attention is paid to both caregiver and patient perspectives regarding the delivery formats, features, and characteristics of eHealth tools. METHOD: Patients with hip (n = 46) and knee OA (n = 14) and their family caregivers (n = 16) participated in in-person focus groups or phone interviews. Participants were shown a mock-up of an eHealth module, and asked to share their preferences regarding the formats, features, and characteristics of the eHealth prehabilitation tool. Data was transcribed verbatim and coded using primary thematic and secondary content analyses. RESULT: Analyses revealed 3 main themes: 1. "easier to understand" emphasizes patients' preferences on delivery formats and features; 2. "what does that mean?" highlights requests for clear and simple information; and 3. "Preparation, right?" shows patients' perspectives on the best time to have access to the eHealth tool. DISCUSSION: Participants' preferences for prehabilitation tools included offering eHealth tools in multiple mediums of delivery (eg, written materials, pictures, videos). Participants preferred simplified information that emphasized the key points and rationale for the knowledge. There were differences in preferred timeline for having access to prehabilitation education, such as some participants wanting to receive prehabilitation well in advance, while others stated just before surgery was adequate. Our findings provide novel and actionable information about patient and caregiver perspectives on features and characteristics of prehabilitation education for patients with hip and knee OA.

The Hip Instructional Prehabilitation Program for Enhanced Recovery (HIPPER) as an eHealth Approach to Presurgical Hip Replacement Education: Protocol for a Randomized Controlled Trial.

BACKGROUND: Osteoarthritis (OA), leading to hip replacement (THR), is a primary contributor to global mobility impairment. In 2018, more than 59,000 THR surgeries were performed in Canada. Health promotion education, such as prehabilitation, is vital to optimizing surgical outcomes. OBJECTIVE: This study aims to evaluate the feasibility of the Hip Instructional Prehabilitation Program for Enhanced Recovery (HIPPER), an eHealth approach to prehabilitation education. METHODS: A single-blind (assessor-blind), 2-arm, feasibility randomized controlled trial will be conducted. We will recruit 40 (HIPPER group, n=20; control group, n=20) older adults with hip OA and on a waitlist for a THR. The HIPPER intervention consists of 12 online, interactive modules. The control group will receive the current standard practice consisting of 2 online educational sessions lasting 2 hours each (webinars). Feasibility outcomes (eg, recruitment and retention rates) will be evaluated. RESULTS: Recruitment started in March 2021. As of April 20, 2021, 18 participants were recruited. All 18 completed T1 measures. Only 1 participant has been scheduled to have a surgery and therefore has been scheduled to complete T2 measures. The remainder of the participants are waiting to be notified of their surgery date. This project was funded by a Canadian Institutes of Health Research Project Grant. Our institute's research ethics board approved this study in November 2016. CONCLUSIONS: Results will lead to refinement of the HIPPER protocol in order to evaluate a standardized and geographically accessible prehabilitation program.

A randomized controlled trial evaluating combination detection of HIV in Malawian sexually transmitted infections clinics.

INTRODUCTION: HIV diagnosis is the necessary first step towards HIV care initiation, yet many persons living with HIV (PLWH) remain undiagnosed. Employing multiple HIV testing strategies in tandem could increase HIV detection and promote linkage to care. We aimed to assess an intervention to improve HIV detection within socio-sexual networks of PLWH in two sexually transmitted infections (STI) clinics in Lilongwe, Malawi. METHODS: We conducted a randomized controlled trial to evaluate an intervention combining acute HIV infection (AHI) screening, contract partner notification and social contact referral versus the Malawian standard of care: serial rapid serological HIV tests and passive partner referral. Enrolment occurred between 2015 and 2019. HIV-seropositive persons (two positive rapid tests) were randomized to the trial arms and HIV-seronegative (one negative rapid test) and -serodiscordant (one positive test followed by a negative confirmatory test) persons were screened for AHI with HIV RNA testing. Those found to have AHI were offered enrolment into the intervention arm. Our primary outcome of interest was the number of new HIV diagnoses made per index participant within participants' sexual and social networks. We also calculated total persons, sexual partners and PLWH (including those previously diagnosed) referred per index participant. RESULTS: A total of 1230 HIV-seropositive persons were randomized to the control arm, and 561 to the intervention arm. Another 12,713 HIV-seronegative or -serodiscordant persons underwent AHI screening, resulting in 136 AHI cases, of whom 94 enrolled into the intervention arm. The intervention increased the number of new HIV diagnoses made per index participant versus the control (ratio: 1.9; 95% confidence interval (CI): 1.2 to 3.1). The intervention also increased the numbers of persons (ratio: 2.5; 95% CI: 2.0 to 3.2), sexual partners (ratio: 1.7; 95% CI: 1.4 to 2.0) and PLWH (ratio: 2.3; 95% CI: 1.7 to 3.2) referred per index participant. CONCLUSIONS: Combining three distinct HIV testing and referral strategies increased the detection of previously undiagnosed HIV infections within the socio-sexual networks of PLWH seeking STI care. Combination HIV detection strategies that leverage AHI screening and socio-sexual contact networks offer a novel and efficacious approach to increasing HIV status awareness.

Evidence on definitions, concepts, outcome instruments, and interventions for chronic fatigue in spinal cord injury: a scoping review protocol.

OBJECTIVE: The objective of this review is to review the existing evidence on definitions, concepts, measurement instruments, and interventions for chronic fatigue in spinal cord injury. INTRODUCTION: Chronic fatigue in people with spinal cord injury is an under-studied issue that affects between 25% and 56.6% of people with spinal cord injury. There are questions about how it is defined and managed due to its complex, multifactorial nature and relationship with related conditions. No overview of chronic fatigue in spinal cord injury exists and we are in need of a shared definition of chronic fatigue, as well as a comprehensive review of concepts and evidence supporting outcome instruments and interventions. INCLUSION CRITERIA: This review will include empirical and non-empirical studies that focus on definitions, concepts, measurement instruments, and interventions for chronic fatigue in spinal cord injury. Studies that focus on peripheral muscle fatigue will only be included if they include chronic fatigue as a secondary outcome. METHODS: This review will be done in three phases. Phase I will provide an overview of definitions of chronic fatigue in spinal cord injury and will include a qualitative analysis of concept attributes and characteristics. Phase II will focus on factors related to chronic fatigue and measurement instruments used to measure chronic fatigue, and phase III will focus on interventions. Full texts will be screened by two independent reviewers against inclusion criteria. Results will be presented in tabular form with a narrative summary.

Effectiveness of eHealth Tools for Hip and Knee Arthroplasty: A Systematic Review.

Objective: This study aimed to compare the effectiveness and costs of eHealth tools with usual care in delivering health-related education to patients' undergoing total hip or knee arthroplasty due to osteoarthritis. Data Sources: Six electronic databases were searched to identify randomized controlled trials and experimental designs (randomized or not) examining the effect of eHealth tools on pre- or post-operative care. Only manuscripts written in English were included. In the current study, no specific primary or secondary outcomes were selected. Any study that investigated the impacts of eHealth tools on hip or knee arthroplasty outcomes were included. Review Methods: Two researchers reviewed all titles and abstracts independently and in duplicate. Two researchers also conducted full-text screening and data extraction from the 26 selected articles. Results: The data were descriptively reported, and themes could emerge from each outcome. Two researchers separately assessed the Risk of Bias for each paper using the Cochrane risk of bias assessment tool. The majority of studies evaluated the impact of eHealth tools on physical (n = 23) and psychosocial outcomes (n = 19). Cost-related outcomes were measured in 7 studies. eHealth tools were found to be equivocal to usual care, with few studies reporting statistically significant differences in physical or psychosocial outcome measures. However, cost-related outcomes showed that using eHealth tools is more cost-effective than usual care. Conclusions: This review demonstrated that eHealth tools might be as effective as usual care, and possibly more cost-effective, a crucial implication for many overly burdened health care systems.

Locally contextualizing understandings of depression, the EPDS, and PHQ-9 among a sample of postpartum women living with HIV in Malawi.

BACKGROUND: The Edinburgh Postnatal Depression Scale (EPDS) and Patient Health Questionnaire-9 (PHQ-9) are widely used depression screening tools, yet perceptions and understandings of their questions and of depression are not well defined in cross-cultural research. METHODS: 30 postpartum women living with HIV in Malawi were recruited from a cohort study and participated in in-depth cognitive interviews. Transcripts were evaluated following an inductive approach to identify common themes. RESULTS: Participants most frequently described looking sad or different than usual, self-isolation, 'thinking too much,' and anger as key symptoms of being depressed. HIV-associated stigma was commonly identified as a cause of depression. The EPDS and PHQ-9 were generally well understood but did not capture all the important symptoms of depression that women described. Participants sometimes requested clarification or rephrasing of certain EPDS and PHQ-9 questions when asked to explain the questions' meanings in their own words, and requested rephrasing more often for EPDS questions than PHQ-9 questions. Few women believed either tool was sufficient to detect depression. LIMITATIONS: Our results may not be generalizable, but are locally contextualized. Women suffering with depression may have been more or less likely to agree to the qualitative interview depending on their comfort level discussing any current depressive symptoms. CONCLUSIONS: Researchers and practitioners who use the EPDS and PHQ-9 should be aware of the tools' limitations in their context and population. New instruments may need to be developed or adaptations to existing tools made to improve accuracy of depression screening and diagnosis in different cultural contexts.

The Influence of Screening, Misclassification, and Reporting Biases on Reported Chlamydia Case Rates Among Young Women in the United States, 2000 Through 2017.

BACKGROUND: National chlamydia case rate trends are difficult to interpret because of biases from partial screening coverage, imperfect diagnostic tests, and underreporting. We examined the extent to which these time-varying biases could influence reported annual chlamydia case rates. METHODS: Annual reported case rates among women aged 15 through 24 years from 2000 through 2017 were obtained from the Centers for Disease Control and Prevention's National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention AtlasPlus tool. Estimates of reporting completeness, diagnostic test sensitivity and specificity, and screening coverage were derived from literature review and expert opinion. We adjusted annual reported case rates for incomplete reporting, imperfect diagnostic tests, and partial screening coverage through a series of corrections, and calculated annual adjusted case rates of correctly diagnosed chlamydia. RESULTS: Adjusted chlamydia case rates among young women were higher than reported case rates throughout the study period. Reported case rates increased over the study period, but adjusted rates declined from 12,900 to 7900 cases per 100,000 person-years between 2000 and 2007. After 2007, adjusted case rates declined to 7500 cases per 100,000 person-years in 2017. Bias from partial screening coverage had a larger impact on case rate magnitude and trend shape than bias from imperfect diagnostic tests or underreporting. CONCLUSIONS: Reported chlamydia case rates may be substantially lower than true chlamydia case rates because of incomplete reporting, imperfect diagnostic tests, and partial screening coverage. Because the magnitude of these biases has declined over time, the differences between reported and adjusted case rates have narrowed, revealing a sharp decline in adjusted case rates even as reported case rates have risen. The decline in adjusted case rates suggests that the rise in reported case rates should not be interpreted strictly as increasing chlamydia incidence, as the observed rise can be explained by improvements in screening coverage, diagnostic tests, and reporting.

Factors Associated With Human Immunodeficiency Virus Infections Linked in Genetic Clusters But Disconnected in Partner Tracing.

BACKGROUND: Successful partner notification can improve community-level outcomes by increasing the proportion of persons living with human immunodeficiency virus (HIV) who are linked to HIV care and virally suppressed, but it is resource intensive. Understanding where HIV transmission pathways may be undetected by routine partner notification may help improve case finding strategies. METHODS: We combined partner notification interview and HIV sequence data for persons diagnosed with HIV in Wake County, NC in 2012 to 2013 to evaluate partner contact networks among persons with HIV pol gene sequences 2% or less pairwise genetic distance. We applied a set of multivariable generalized estimating equations to identify correlates of disparate membership in genetic versus partner contact networks. RESULTS: In the multivariable model, being in a male-male pair (adjusted odds ratio [AOR], 16.7; P = 0.01), chronic HIV infection status (AOR, 4.5; P < 0.01), and increasing percent genetic distance between each dyad member's HIV pol gene sequence (AOR, 8.3 per each 1% increase, P < 0.01) were all associated with persons with HIV clustering but not being identified in the partner notification network component. Having anonymous partners or other factors typically associated with risk behavior were not associated. CONCLUSIONS: Based on genetic networks, partnerships which may be stigmatized, may have occurred farther back in time or may have an intervening partner were more likely to be unobserved in the partner contact network. The HIV genetic cluster information contributes to public health understanding of HIV transmission networks in these settings where partner identifying information is not available.

Female adherence self-efficacy before and after couple HIV testing and counseling within Malawi's Option B+ program.

Adherence self-efficacy, belief in one's ability to adhere to daily medication, is strongly associated with antiretroviral therapy (ART) adherence and preventing mother-to-child HIV transmission. Couple-based interventions could enhance self-efficacy and adherence. We assessed the relationship between couple HIV testing and counseling (cHTC) and adherence self-efficacy using a 100-point culturally-adapted adherence self-efficacy scale (ASES). Secondarily, we explored the relationship between ASES and ART adherence. Ninety HIV-positive pregnant women at an antenatal clinic in Lilongwe, Malawi were enrolled in an observational cohort study. They were assessed with ASES immediately before and one month after receiving cHTC. Median ASES scores were 100 (IQR 95, 100) before and 100 (IQR 99, 100) after cHTC; there was a significant median difference (p = 0.02) for participants before and after cHTC. This change in ASES scores was associated with the odds of self-reported ART adherence in the full population (OR 1.1, p = 0.01), and there was a trend in the same direction for participants with imperfect baseline ASES scores (OR 1.1, p = 0.2). In our population, adherence self-efficacy and ART adherence were both quite high, and those who had room to improve in self-efficacy may have benefited from cHTC, which in turn could impact ART adherence and ultimately mother-to-child transmission.

Predictors of physical therapists' intentions to counsel for smoking cessation: Implications for practice and professional education.

OBJECTIVE: This study explored factors predicting intention (predominant construct in social cognitive behavioral models) for smoking cessation (SC) counseling that may provide salient information for designing/targeting SC counseling training for physical therapists (PTs). Design: Cross-sectional questionnaire survey of PTs licensed to practice in Canada. Methods: Self-efficacy items and PT views were assessed for internal consistency (Cronbach's α) and data reduced using principal axis factor analysis. Hierarchical linear regression modeling assessed predictors of intention to counsel for SC. Results: Internal consistency: self-efficacy and PT views: r = 0.937, r = 0.821, respectively. Factor structures from self-efficacy: "skills and knowledge" and "clinic incidentals" (57% total variance); from PT views': "professional role" and "role modeling" (63.8% total variance). Significant predictors of intent to counsel for SC were "professional role" (ß = 0.54, p ≤ 0.001), and "skills and knowledge" (ß = 0.23, p ≤ 0.001). Conclusions: Physical therapists' intent to engage in SC counseling increases when they consider it their "professional role." Encouraging PTs to view SC counseling as a professional role as well as increasing SC counseling self-efficacy focusing on skills and knowledge to do so needs to be incorporated into entry-level academic physical therapy programs and continuing professional PT education.

Preferences for Pre-exposure Prophylaxis Service Delivery Among Female Sex Workers in Malawi: A Discrete Choice Experiment.

Female sex workers (FSW) in Malawi have among the highest HIV prevalence estimates worldwide. Daily oral pre-exposure prophylaxis (PrEP) is an effective HIV prevention method, yet preferences for PrEP delivery among FSW are lacking. Eight focus group discussions, a literature review, and cognitive interviews were conducted to identify modifiable PrEP delivery attributes and inform discrete-choice experiment (DCE) development for FSW in Lilongwe. Enrolled FSW received an interviewer-assisted DCE. Data were analyzed using mixed logit regression. Dispensing location was most preferred, followed by the provision of additional services. Women preferred receiving PrEP at family planning clinics or non-governmental organization run drop-in centers. Cervical cancer screening was the most preferred additional service, while pregnancy testing and partner risk reduction counseling were less valued. This study was the first study to examine PrEP delivery preferences in Malawi using DCE-a powerful elicitation tool to apply to other key populations at risk for HIV.

High Cancer Burden Among Antiretroviral Therapy Users in Malawi: A Record Linkage Study of Observational Human Immunodeficiency Virus Cohorts and Cancer Registry Data.

BACKGROUND: With antiretroviral therapy (ART), AIDS-defining cancer incidence has declined and non-AIDS-defining cancers (NADCs) are now more frequent among human immunodeficiency virus (HIV)-infected populations in high-income countries. In sub-Saharan Africa, limited epidemiological data describe cancer burden among ART users. METHODS: We used probabilistic algorithms to link cases from the population-based cancer registry with electronic medical records supporting ART delivery in Malawi's 2 largest HIV cohorts from 2000-2010. Age-adjusted cancer incidence rates (IRs) and 95% confidence intervals were estimated by cancer site, early vs late incidence periods (4-24 and >24 months after ART start), and World Health Organization (WHO) stage among naive ART initiators enrolled for at least 90 days. RESULTS: We identified 4346 cancers among 28 576 persons. Most people initiated ART at advanced WHO stages 3 or 4 (60%); 12% of patients had prevalent malignancies at ART initiation, which were predominantly AIDS-defining eligibility criteria for initiating ART. Kaposi sarcoma (KS) had the highest IR (634.7 per 100 000 person-years) followed by cervical cancer (36.6). KS incidence was highest during the early period 4-24 months after ART initiation. NADCs accounted for 6% of new cancers. CONCLUSIONS: Under historical ART guidelines, NADCs were observed at low rates and were eclipsed by high KS and cervical cancer burden. Cancer burden among Malawian ART users does not yet mirror that in high-income countries. Integrated cancer screening and management in HIV clinics, especially for KS and cervical cancer, remain important priorities in the current Malawi context.

Prediction of HIV Transmission Cluster Growth With Statewide Surveillance Data.

BACKGROUND: Prediction of HIV transmission cluster growth may help guide public health action. We developed a predictive model for cluster growth in North Carolina (NC) using routine HIV surveillance data. METHODS: We identified putative transmission clusters with ≥2 members through pairwise genetic distances ≤1.5% from HIV-1 pol sequences sampled November 2010-December 2017 in NC. Clusters established by a baseline of January 2015 with any sequences sampled within 2 years before baseline were assessed for growth (new diagnoses) over 18 months. We developed a predictive model for cluster growth incorporating demographic, clinical, temporal, and contact tracing characteristics of baseline cluster members. We internally and temporally externally validated the final model in the periods January 2015-June 2016 and July 2016-December 2017. RESULTS: Cluster growth was predicted by larger baseline cluster size, shorter time between diagnosis and HIV care entry, younger age, shorter time since the most recent HIV diagnosis, higher proportion with no named contacts, and higher proportion with HIV viremia. The model showed areas under the receiver-operating characteristic curves of 0.82 and 0.83 in the internal and temporal external validation samples. CONCLUSIONS: The predictive model developed and validated here is a novel means of identifying HIV transmission clusters that may benefit from targeted HIV control resources.

Sustained Sexual Behavior Change After Acute HIV Diagnosis in Malawi.

BACKGROUND: Identification of acute HIV infection (AHI) allows for important opportunities for HIV prevention through behavior change and biomedical intervention. Here, we evaluate changes in sexual risk behaviors among persons with AHI enrolled in a combined behavioral and biomedical intervention designed to reduce onward transmission of HIV. METHODS: Participants were randomized to standard HIV counseling, a multisession behavioral intervention, or a multisession behavioral intervention plus antiretrovirals. Sexual behaviors were assessed periodically over 1 year. RESULTS: Four weeks after diagnosis, the predicted probability of reporting multiple sexual partners decreased from 24% to 9%, and the probability of reporting unprotected sex decreased from 71% to 27%. These declines in sexual risk behaviors were sustained over follow-up irrespective of study arm. CONCLUSIONS: Diagnosis of AHI alone may be sufficient to achieve immediate and sustained behavior change during this highly infectious period.
