RESUMO

BACKGROUND: Since 2000, there has been a substantial global reduction in the vertical transmission of HIV. Despite effective interventions, gaps still remain in progress towards elimination in many low-income and middle-income countries. We developed a mathematical model to determine the most cost-effective combinations of interventions to prevent vertical transmission. METHODS: We developed a 12-month Markov model to follow a cohort of women of childbearing age (aged 15-49 years) in Zambia (n=1 107 255) who were either pregnant, in delivery, or breastfeeding; the population included in the model reflects the estimated number of pregnant women in Zambia from the 2018 Zambia Demographic and Health Survey. The model incorporated nine interventions: infant prophylaxis; three different HIV retesting schedule options; oral pre-exposure prophylaxis; maternal peer-support groups; regimen shift; tracing of loss to follow-up; and point-of-care viral load testing. We analysed incident HIV infections among mothers and infants, intervention costs, and evaluated 190 scenarios of different combinations of inventions to calculate the incremental cost-effectiveness ratios (ICERs) over 1 year. FINDINGS: Three interventions with the greatest reduction in vertical transmission, individually, were support groups for 80% of those in need (35% reduction in infant infections), HIV retesting schedules (6·5% reduction), and infant prophylaxis (4·5% reduction). Of all 190 scenarios evaluated, eight were on the cost-effectiveness frontier (ie, were considered to be cost-effective); all eight included increasing infant prophylaxis, regimen shift, and use of support groups. Excluding the highest-cost scenarios, for a 1-22% increase in total budget, 23-43% of infant infections could be prevented, producing ICERs between US$244 and $16 242. INTERPRETATION: Using the interventions modelled, it is possible to reduce vertical transmission and to cost-effectively prevent up to 1734 infant HIV infections (43% reduction) in Zambia over a period of 1 year. To optimise their effect, these interventions must be scaled with fidelity. Future work is needed to incorporate evidence on additional innovative interventions and HIV risk factors, and to apply the model to other country contexts to support targeted implementation and resource use.

RESUMO

OBJECTIVES: There is an unmet need for therapeutically relevant biomarkers for advanced penile squamous cell carcinoma (pSCC). Proposed immunohistochemistry (IHC)-based biomarkers include programmed death-ligand 1 (PD-L1), trophoblast cell-surface antigen 2 (TROP2), and nectin-4; however, there is a paucity of data pertaining to these biomarkers. Herein, we investigated the expression of PD-L1, TROP2, and nectin-4 in a well-annotated cohort of pSCCs. METHODS: A single-institution pathology archive was queried for patients who had a partial or total penectomy for pSCC between January 2000 and December 2022. Whole-slide sections were stained with antibodies against PD-L1 (22C3), TROP2, and nectin-4. Expression in tumor cells was quantified using H-scores (0-300). Associations between IHC expression, human papilloma virus (HPV) status, clinicopathologic findings, and outcome parameters were evaluated. RESULTS: This study included 121 patients. For PD-L1, the median combined positive and H-scores were 1 and 0, respectively; 32.7 % of the cases had an H-score>0. Compared to PD-L1-negative tumors, PD-L1-positive tumors had higher pT stage and grade. The median TROP2 and nectin-4 H-scores were 230 and 140, respectively, with high TROP2 and nectin-4, defined by an H-score>200, noted in 80.7 % and 10.9 % of cases, respectively. High-risk HPV-positive cases had higher TROP2 and nectin-4 scores compared to HPV-negative cases. Patients with high TROP2 expression had significantly more disease progression, and patients with high nectin-4 expression had significantly fewer deaths due to disease. CONCLUSIONS: High expression of TROP2 and nectin-4 in pSCC support evaluation of these markers as therapeutic targets pending validation of our findings.

RESUMO

PURPOSE: The purpose of this study is to evaluate the quality of patient education materials accessible through popular online search engines regarding anterior cruciate ligament (ACL) injuries and anterior cruciate ligament reconstruction (ACLR).  Methods: Two search terms ("ACL surgery" and "ACL reconstruction") were entered into three search engines (Google, Yahoo, and Bing). The quality of information was scored using a novel scoring system developed and overseen by sports medicine orthopedic clinical research fellows and fellowship-trained orthopedic surgeons. Website quality, credibility, and readability were further assessed by the DISCERN score, Journal of the American Medical Association (JAMA) benchmark criteria, and Flesch-Kincaid Reading Grade Level (FKRGL), respectively. The Health On the Net Code of Conduct (HONcode) certification was also utilized to assess the transparency of health information for each website. RESULTS: We evaluated 39 websites. The average score for all websites was 11.2±5.6 out of 28 total points. Six out of the 39 websites (41%) were HONcode certified. The websites that contained HONcode certification had a higher average JAMA benchmark score (3.5±0.7) and DISCERN score (44.6±14.7) when compared to the websites without the certification, 2.2±1.2 and 37.6 ± 15.9 for JAMA and DISCERN, respectively. The mean JAMA benchmark score was 2.7±1.2 (67.5%) for all websites out of a possible four points. The average FKRGL for all 39 websites was 10.0±2.0 (range: 5.4-13). CONCLUSION: The quality of patient education materials accessible on the internet regarding ACL injuries and ACLR can be misleading and directly impact the patient's decision-making process essential to the patient-physician relationship over the past decade. CLINICAL RELEVANCE: The internet can be a helpful online resource, however, surgeon clarification and consultation with qualified healthcare professionals are strongly recommended prior to clinical decision-making regarding potential treatment options.

RESUMO

INTRODUCTION: Reductions in HIV acquisition have slowed, and the global community is significantly off track from global goals. Oral pre-exposure prophylaxis (PrEP) alone cannot address the diverse needs of the millions of people at risk of HIV acquisition. Long-acting injectable cabotegravir (CAB-LA) received United States Food and Drug Administration approval for HIV prevention in December 2021. When studied, CAB-LA demonstrated high effectiveness, provides months of protection versus daily use, is preferred by some users and has the potential to achieve commodity cost reduction. These factors position CAB-LA to catalyse transformation in HIV prevention. Significant work must be undertaken to ensure at-scale uptake in low- and middle-income countries. Leveraging decades of product introduction experience, Clinton Health Access Initiative (CHAI) has developed an innovative roadmap to support equitable CAB-LA introduction, comprising tightly executed market-shaping, product development, regulatory, and programmatic and implementation action. DISCUSSION: Proven models exist (e.g. long-acting reversible contraceptives, paediatric tuberculosis treatment and antiretrovirals (ARVs), such as paediatric dolutegravir and tenofovir disoproxil fumarate, lamivudine, and dolutegravir) for partnership-driven, accelerated, impactful product introduction. Based on learnings from these models and needs in the prevention space, CHAI developed a roadmap to maximize the near-term impact of CAB-LA and accelerate the development of, access to and impact of quality-assured, low-cost generic CAB-LA. This roadmap is intended to inform introduction planning and investment decision-making across a range of stakeholders, including donors, governments, manufacturers and other partners working in the HIV prevention space. Elements include (1) ensuring coordination and alignment across partners, and avoiding redundancy experienced during oral PrEP introduction; (2) preparing national programmes and providing support to maximize impact, including the development of national policies, guidelines and introduction plans; system strengthening; quantification and procurement; and addressing evidence needs, among other areas; (3) supporting community engagement, ensuring that demand generation and delivery approaches are person-centred and community-led; (4) incentivizing generic product development through, for example, milestone-based commercialization incentives and product development cost-sharing; and (5) expediting regulatory reviews. CONCLUSIONS: Accelerating access to affordable, generic CAB-LA can transform progress towards HIV epidemic control. This vision of impact at scale in prevention is achievable, if informed by results-backed approaches to introduction.

RESUMO

Introduction: Women in sub-Saharan Africa (SSA) experience the world's highest rates of both HIV infection and unintended pregnancy. The Dual Prevention Pill (DPP) is a novel multipurpose prevention technology (MPT) that co-formulates HIV pre-exposure prophylaxis (PrEP) and combined hormonal oral contraception into a single daily pill. As a dual indication product, the DPP may be preferred by women facing these overlapping health risks. However, most SSA countries face severe healthcare resource constraints. Research is needed to assess whether, in what populations, and in what use cases the DPP would be cost-effective. Methods: We augmented an agent-based SSA HIV model with maternal health parameters including unintended pregnancy, abortion, and maternal mortality. Based on a previous market analysis, we assumed a primary DPP user population of current oral contraceptive users ages 25-49, and alternative user populations in different risk groups (age 15-24, sex workers, HIV-serodiscordant couples) and baseline product use profiles (unmet need for contraception, oral PrEP use, condom use). In three geographies (western Kenya, Zimbabwe, South Africa), we estimated HIV infections averted, pregnancies averted, disability-adjusted life-years (DALYs) averted, and the incremental cost-effectiveness ratio (ICER) over a 30-year time horizon, assuming equivalent adherence to the DPP as to oral contraceptives, higher adherence, or lower adherence. Results: The DPP is likely to be a cost-effective alternative to oral PrEP among users in need of contraception. Among women not already using PrEP, the DPP is likely to be cost-saving in sex workers and serodiscordant couples. The DPP is unlikely to be cost-effective in oral contraceptive users in the general population. Switching from oral contraception to the DPP could be net harmful in some settings and populations if it were to substantially reduces adherence to oral contraception. Results were robust to a range of time horizons or discount rates. Conclusion: The DPP has the potential to be cost-effective and cost-saving in populations at substantial HIV risk. Outcomes are sensitive to adherence, implying that effective counseling and decision-making tools for users considering the DPP will be essential. More research is needed to understand real-life adherence patterns and ensure health benefits achieved from contraception alone are not lost.

RESUMO

BACKGROUND: The COVID-19 pandemic has overwhelmed health systems with knock on effects on diagnosis, treatment, and care. To mitigate the impact, the government of Zimbabwe enforced a strict lockdown beginning 30 March 2020 which ran intermittently until early 2021. In this period, the Ministry of Health and Childcare strategically prioritized delivery of services leading to partial and full suspension of services considered non-essential, including HIV prevention. As a result, Voluntary Medical Male Circumcision (VMMC) services were disrupted leading to an 80% decline in circumcisions conducted in 2020. Given the efficacy of VMMC, we quantified the potential effects of VMMC service disruption on new HIV infections in Zimbabwe. METHODS: We applied the GOALS model to evaluate the impact of COVID-19-related disruptions on reducing new HIV infections over 30-years. GOALS is an HIV simulation model that estimates number of new HIV infections based on sexual behaviours of population groups. The model is parameterized based on national surveys and HIV program data. We hypothesized three coverage scenarios by 2030: scenario I - pre-COVID trajectory: 80% VMMC coverage; Scenario II - marginal COVID-19 impact: 60% VMMC coverage, and scenario III - severe COVID-19 impact: 45% VMMC coverage. VMMC coverage between 2020 and 2030 was linearly interpolated to attain the estimated coverage and then held constant from 2030 to 2050, and discounted outcomes at 3%. RESULTS: Compared to the baseline scenario I, in scenario II, we estimated that the disruption of VMMC services would generate an average of 200 (176-224) additional new infections per year and 7,200 new HIV infections over the next 30 years. For scenario III, we estimated an average of 413 (389-437) additional new HIV infections per year and 15,000 new HIV infections over the next 30 years. The disruption of VMMC services could generate additional future HIV treatment costs ranging from $27 million to $55 million dollars across scenarios II and III, respectively. CONCLUSION: COVID-19 disruptions destabilized delivery of VMMC services which could contribute to an additional 7,200 new infections over the next 30 years. Unless mitigated, these disruptions could derail the national goals of reducing new infections by 2030.

RESUMO

BACKGROUND: Long-acting injectable cabotegravir pre-exposure prophylaxis (PrEP) is recommended by WHO as an additional option for HIV prevention in sub-Saharan Africa, but there is concern that its introduction could lead to an increase in integrase-inhibitor resistance undermining treatment programmes that rely on dolutegravir. We aimed to project the health benefits and risks of cabotegravir-PrEP introduction in settings in sub-Saharan Africa. METHODS: With HIV Synthesis, an individual-based HIV model, we simulated 1000 setting-scenarios reflecting both variability and uncertainty about HIV epidemics in sub-Saharan Africa and compared outcomes for each with and without cabotegravir-PrEP introduction. PrEP use is assumed to be risk-informed and to be used only in 3-month periods (the time step for the model) when having condomless sex. We consider three groups at risk of integrase-inhibitor resistance emergence: people who start cabotegravir-PrEP after (unknowingly) being infected with HIV, those who seroconvert while on PrEP, and those with HIV who have residual cabotegravir drugs concentrations during the early tail period after recently stopping PrEP. We projected the outcomes of policies of cabotegravir-PrEP introduction and of no introduction in 2022 across 50 years. In 50% of setting-scenarios we considered that more sensitive nucleic-acid-based HIV diagnostic testing (NAT), rather than regular antibody-based HIV rapid testing, might be used to reduce resistance risk. For cost-effectiveness analysis we assumed in our base case a cost of cabotegravir-PrEP drug to be similar to oral PrEP, resulting in a total annual cost of USD$144 per year ($114 per year and $264 per year considered in sensitivity analyses), a cost-effectiveness threshold of $500 per disability-adjusted life years averted, and a discount rate of 3% per year. FINDINGS: Reflecting our assumptions on the appeal of cabotegravir-PrEP, its introduction is predicted to lead to a substantial increase in PrEP use with approximately 2·6% of the adult population (and 46% of those with a current indication for PrEP) receiving PrEP compared with 1·5% (28%) without cabotegravir-PrEP introduction across 20 years. As a result, HIV incidence is expected to be lower by 29% (90% range across setting-scenarios 6-52%) across the same period compared with no introduction of cabotegravir-PrEP. In people initiating antiretroviral therapy, the proportion with integrase-inhibitor resistance after 20 years is projected to be 1·7% (0-6·4%) without cabotegravir-PrEP introduction but 13·1% (4·1-30·9%) with. Cabotegravir-PrEP introduction is predicted to lower the proportion of all people on antiretroviral therapy with viral loads less than 1000 copies per mL by 0·9% (-2·5% to 0·3%) at 20 years. For an adult population of 10 million an overall decrease in number of AIDS deaths of about 4540 per year (-13 000 to -300) across 50 years is predicted, with little discernible benefit with NAT when compared with standard antibody-based rapid testing. AIDS deaths are predicted to be averted with cabotegravir-PrEP introduction in 99% of setting-scenarios. Across the 50-year time horizon, overall HIV programme costs are predicted to be similar regardless of whether cabotegravir-PrEP is introduced (total mean discounted annual HIV programme costs per year across 50 years is $151·3 million vs $150·7 million), assuming the use of standard antibody testing. With antibody-based rapid HIV testing, the introduction of cabotegravir-PrEP is predicted to be cost-effective under an assumed threshold of $500 per disability-adjusted life year averted in 82% of setting-scenarios at the cost of $144 per year, in 52% at $264, and in 87% at $114. INTERPRETATION: Despite leading to increases in integrase-inhibitor drug resistance, cabotegravir-PrEP introduction is likely to reduce AIDS deaths in addition to HIV incidence. Long-acting cabotegravir-PrEP is predicted to be cost-effective if delivered at similar cost to oral PrEP with antibody-based rapid HIV testing.

RESUMO

African American (AA) churches are valuable partners in implementing health promotion programming (HPP) to combat health disparities. The study purpose was to evaluate AA church characteristics associated with enrollment into the FAITH! (Fostering African American Improvement in Total Health) Trial, a community-based, cluster randomized controlled trial (RCT) of a mobile health intervention for cardiovascular health promotion among AA churches. Churches located in Minneapolis-St. Paul and Rochester, Minnesota were invited to complete an electronic screening survey and follow-up telephone interview including the PREACH (Predicting Readiness to Engage African American Churches in Health) tool to assess church characteristics and infrastructure for HPP. The primary outcome was church enrollment in the FAITH! Trial. Key predictors included overall PREACH scores and its subscales (Personnel, Physical Structure, Faith-based Approach, Funding), congregation size, and mean congregation member age. Of the 26 churches screened, 16 (61.5%) enrolled in the trial. The enrolled churches had higher overall mean PREACH scores (36.1 vs. 30.2) and subscales for Personnel (8.8 vs. 5.6), Faith-based Approach (11.0 vs. 9.6), and Funding (7.3 vs. 4.8) compared with non-enrolled churches; all differences were not statistically significant due to small sample size. Twelve (75.0%) of the enrolled churches had >75 members versus six (60.0%) of the non-enrolled churches. Twelve (80.0%) of the enrolled churches had an average congregation member age ≤54 years versus six (67.0%) of the non-enrolled churches. AA churches enrolling into a community-based RCT reported greater infrastructure for HPP, larger congregations, and members of younger age. These characteristics may be helpful to consider among researchers partnering with AA churches for HPP studies.

RESUMO

BACKGROUND: African Americans (AAs) and other racial/ethnic minority groups continue to be underrepresented in medical research and clinical trials. Failure to create more racially diverse research cohorts can exacerbate existing health disparities among these groups. OBJECTIVE: To investigate best practices and strategies for enhancing participation of AAs in medical research among attendees of a preconference Institute at a faith-based public health conference. DESIGN: Qualitative study using semi-structured interviews. PARTICIPANTS: A total of 21 out of 29 attendees (90% AA) of the Institute (72% response rate). APPROACH: A culturally tailored preconference Institute was held at the 2017 Healthy Churches 2020 National Conference. The Institute was led by AA researchers focused on underrepresentation of AAs in medical research. Semi-structured interviews were conducted 1-year post-Institute (n=21) and were audio-recorded, transcribed verbatim, and reviewed using thematic analysis. KEY RESULTS: The majority of attendees reported that they were more likely to participate in medical research after attending the Institute (75%). Salient learning points reported by attendees demonstrated attainment of the Institute objectives. Key themes emerged describing barriers preventing AAs from participating in medical research including fear/lack of trust, lack of information on research projects, and not being approached to participate. Key themes regarding facilitators for participation in medical research by AAs were clear communication of study objectives and research benefits along with trust in researchers. CONCLUSIONS: Attendees' perceptions of participation in medical research were largely positive following their attendance at a conference-based Institute aimed to address the underrepresentation of AAs in medical research. Our culturally tailored approach to disseminating knowledge of the research process could extend to other national conferences prioritizing AAs and other racial/ethnic minority populations to improve research participation.

RESUMO

BACKGROUND: Physicians play a key role in mitigating and managing costs in healthcare which are rising. OBJECTIVE: Conduct a cross-sectional survey in 2017, comparing results to a 2012 survey to understand US physicians' evolving attitudes and strategies concerning healthcare costs. PARTICIPANTS: Random sample of 1200 US physicians from the AMA Masterfile. MEASURES: Physician views on responsibility for costs of care, enthusiasm for cost-saving strategies, cost-consciousness scale, and practice strategies on addressing cost. KEY RESULTS: Among 1200 physicians surveyed in 2017, 489 responded (41%). In 2017, slightly more physicians reported that physicians have a major responsibility for addressing healthcare costs (32% vs. 27%, p = 0.03). In 2017, more physicians attributed "major responsibility" for addressing healthcare costs to pharmaceutical companies (68% vs. 56%, p < 0.001) and hospital and health systems (63% vs. 56%%, p = 0.008) in contrast to 2012. Fewer respondents in 2017 attributed major responsibility for addressing costs to trial lawyers (53% vs. 59%, p = 0.007) and patients (42% vs. 52%, p < 0.0001) as compared to 2012. Physician enthusiasm for patient-focused cost-containment strategies like high deductible health plans and higher co-pays (62% vs. 42%, p < 0.0001 and 62% vs. 39%, p < 0.0001, not enthusiastic, respectively) declined. Physicians reported that when they discussed cost, it resulted in a change in disease management 56% of the time. Cost-consciousness within surveyed physicians had not changed meaningfully in 2017 since 2012 (31.7 vs. 31.2). Most physicians continued to agree that decision support tools showing costs would be helpful in their practice (> 70%). After adjusting for specialty, political affiliation, practice setting, age, and gender, only democratic/independent affiliation remained a significant predictor of cost-consciousness. CONCLUSIONS AND RELEVANCE: US physicians increasingly attribute responsibility for rising healthcare costs to organizations and express less enthusiasm for strategies that increase patient out-of-pocket cost. Interventions that focus on physician knowledge and communication strategies regarding cost of care may be helpful.

RESUMO

OBJECTIVES: We explored the impact and cost-effectiveness of preexposure prophylaxis (PrEP) provision to different populations in South Africa, with and without effective self-selection by individuals at highest risk of contracting HIV (through concurrent partnerships and/or commercial sex). DESIGN AND METHODS: We used a previously developed HIV transmission model to analyse the epidemiological impact of PrEP provision to adolescents, young adults, pregnant women, female sex workers (FSWs) and (MSM), and data from South African PrEP programmes to estimate the cost and cost-effectiveness of PrEP (cost in 2019 USD per HIV infection averted over 20 years, 2019, 38). PrEP uptake followed data from early implementation sites, scaled-up linearly over 3 years, with target coverage set to 18% for adolescents, young adults and pregnant women, 30% for FSW and 54% for MSM. RESULTS: The annual cost of PrEP provision ranges between $75 and $134 per person. PrEP provision adolescents and young adults, regardless of risk behaviour, will each avert 3.2--4.8% of HIV infections over 20 years; provision to high-risk individuals only has similar impact at lower total cost. The incremental cost per HIV infection averted is lower in high-risk vs. all-risk sub-populations within female adolescents ($507 vs. $4537), male adolescents ($2108 vs. $5637), young women ($1592 vs. $10 323) and young men ($2605 vs. $7715), becoming cost saving within 20 years for high-risk adolescents, young women, MSM and FSWs. CONCLUSION: PrEP is an expensive prevention intervention but uptake by those at the highest risk of HIV infection will make it more cost-effective, and cost-saving after 14-18 years.

RESUMO

PURPOSE: The purpose of this study was to describe participant characteristics and effective teaching methods at a national continuing medical education (CME) conference on hospital medicine for physician assistants (PAs) and nurse practitioners (NPs). METHODS: In this cross-sectional study, participants provided demographic information and teaching effectiveness scores for each presentation. Associations between teaching effectiveness score and presentation characteristics were determined. RESULTS: In total, 163 of 253 participants (64.4%) completed evaluations of 28 presentations. Many of the participants were younger than 50 years (69.0%), had practiced for fewer than 5 years (41.5%), and worked in nonacademic settings (76.7%). Teaching effectiveness scores were significantly associated with the use of clinical cases (perfect scores for 68.8% of presentations with clinical cases vs. 59.8% without; P = .04). CONCLUSION: Many PAs and NPs at an HM CME conference were early-career clinicians working in nonacademic settings. Presenters at CME conferences in hospital medicine should consider using clinical cases to improve their teaching effectiveness among PA and NP learners.

RESUMO

Objective: Understanding gender differences in self-perception of health (SPH) and self-efficacy can inform the design of tailored programs to improve health behaviors. We aimed to assess gender-specific differences in SPH and self-efficacy for maintaining wellness habits at a work-place wellness center. Methods: A workplace wellness center member survey was conducted in 2016. Information about SPH and self-efficacy to maintain wellness habits was assessed. Data were analyzed to assess gender differences in SPH and self-efficacy. Results: The survey was completed by 2784 members (mean age, 49.2 years; 68.2% women). SPH was similar between genders despite more men reporting health problems such as hypertension, diabetes, high cholesterol, and cigarette smoking. Women had higher self-efficacy about maintaining healthy diet, but the difference was not clinically meaningful. Women had lower self-efficacy in their ability to maintain physical activity. Conclusions: In this large cohort of worksite wellness center members, men and women had similar self-perception of health despite higher disease burden among men. Women had lower self-efficacy in their ability to maintain physical activity level but similar self-efficacy for maintaining healthy diet. These differences may inform the design of tailored wellness programs to meet the needs of both genders.

RESUMO

Physicians play a key role in implementing health policy, and US physicians were split in their opinions about the Affordable Care Act (ACA) soon after its implementation began. We readministered elements of a prior survey of US physicians to a similar sample to understand how US physicians' opinions of the ACA may have changed over a crucial five-year implementation period (2012-17), and we compared responses across both surveys. Of the 1,200 physicians to whom we sent a survey in the summer of 2017, 489 responded (a response rate of 41 percent). A majority of respondents (60 percent) believed that the ACA had improved access to care and insurance, yet many (43 percent) felt that it had reduced the affordability of coverage. More physicians agreed in 2017 than in 2012 that the ACA "would turn United States health care in the right direction" (53 percent versus 42 percent), despite reporting perceived worsening in several practice conditions over the same time period. After we adjusted for specialty, political party affiliation, practice setting type, perceived social responsibility, age, and sex, we found that only political party affiliation was a significant predictor of support for the ACA in the 2017 results.

RESUMO

OBJECTIVES: Long-term follow-up is important for determining performance characteristics of thyroid fine-needle aspiration (FNA). METHODS: Histologic or 3 or more years of clinical follow-up was used to calculate performance characteristics of thyroid FNA before and after implementation of The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). The impact of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) classification was also investigated. RESULTS: Follow-up was obtained for 1,277/1,134 and 1,616/1,393 aspirates/patients (median clinical follow-up, 9.9 and 4.4 years, pre- and post-TBSRTC, respectively). Nondiagnostic, suspicious for follicular neoplasm, and suspicious for malignancy (SFM) diagnoses decreased and benign diagnoses increased post-TBSRTC, while atypical rate remained less than 1%. Negative predictive value for benign nodules and positive predictive value (PPV) for SFM increased significantly. Eleven nodules were reclassified as NIFTP, slightly decreasing PPV/risk of malignancy (ROM). CONCLUSIONS: Appropriate ROM for thyroid FNA can be achieved through application of TBSRTC terminology with minimal use of atypical category.

RESUMO

Striking cardiovascular health disparities exist among African-Americans in Minnesota compared to Whites; however, community-based interventions to address cardiovascular disease risk are lacking. This study explored participant perceptions of a culturally tailored, cardiovascular disease prevention program developed using a community-based participatory research process. Research participation perceptions, program benefits, and program satisfaction/acceptability were analyzed using a mixed-methods approach. Overall, acceptability was high. Findings highlight the favorable inclusion of African-Americans (research perception), knowledge gained about healthy lifestyle practices (benefits), and quality of the curriculum/speakers (satisfaction). Community-based participatory research may be useful in fostering the acceptability of behavior change interventions among marginalized African-American communities.

RESUMO

BACKGROUND/AIMS: The clinical utility of vedolizumab (VDZ) trough levels (VTLs) in inflammatory bowel disease (IBD) is not well defined. The aims of this study are to determine the median VTLs and frequency of detected antibodies, the correlation of VTLs with C-reactive protein (CRP) and mucosal healing (MH), and the change in clinical management based on VTLs. METHODS: A cross-sectional study of IBD patients treated with VDZ with VTLs checked between July 1, 2016, and March 1, 2017, was conducted. Mucosal healing was defined as absence of mucosal ulcers in Crohn's disease (CD) and Mayo endoscopic score ≤1 for ulcerative colitis (UC). Normal CRP was defined as ≤8 mg/L. RESULTS: A total of 171 patients (62% CD, 31% UC, 7% indeterminate colitis) were included. Median VTLs was 15.3 ug/mL (range, 0-60), and 1 patient had detectable antibodies to VDZ. Patients with a normal CRP had a median VTLs of 17.3 ug/mL vs 10.7 ug/mL in high CRP patients (P = 0.046). This was noted in CD (20.3 vs 10.4 ug/mL; P = 0.005) but not in UC patients (14.4 vs 20.8; P = 0.72). Mucosal healing was achieved in 35% of patients (37 of 105); among these, median VTLs was 13.7 ug/mL vs 16.1 ug/mL in patients who did not achieve MH (P = 0.64). Vedolizumab trough levels resulted in a change in clinical management in 73%. CONCLUSIONS: Our cohort showed a low rate of immunogenicity to VDZ and an association between VTLs and CRP in CD but not in UC patients. No relationship between VTLs and MH was detected. Vedolizumab trough level measurements altered management in approximately three fourths of patients.

RESUMO

PURPOSE: Novel approaches are needed to enhance employee well-being and perhaps supervisors can be an effective agent for worksite health promotion. The aim of this study was to examine the supervisor's perceived needs, barriers, and role for influencing employee well-being for incorporation into program development. DESIGN: Semistructured, qualitative interviews of supervisors. SETTING: Large, integrated academic health-care organization with over 30 000 employees and 2600 supervisors having access to comprehensive well-being programs and a successful well-being champion network comprised of 600 champions. PARTICIPANTS: Twenty supervisors representing clinical, research, and administrative units. METHODS: Semistructured, one-on-one interviews were conducted and audio recorded. Analysis included content log development and open coding by a trained analyst to reveal key themes. More formalized content coding using specialized software for qualitative analyses was also conducted. RESULTS: Supervisor responses were wide ranging regarding their perceived and desired role in promoting workplace well-being. Barriers from the supervisor perspective included high current workload, ambivalence about promoting wellness, lack of support from leadership, lack of flexibility and control at work, and difficulty accessing on-site resources. They perceived their potential role in well-being as remaining a positive role model and encouraging their staff in wellness activities. CONCLUSION: Although findings are generated from a small sample size, these qualitative data provide compelling and early insights into building a workplace well-being strategy leveraging an underutilized key stakeholder, the workplace supervisor.

RESUMO

BACKGROUND: Several specialty societies participate in the Choosing Wisely (CW) campaign in an attempt to reduce waste in health care spending. We surveyed internal medicine (IM) residents with an objective of classifying knowledge of and confidence in using the American Society of Hematology (ASH) CW principles in hemostasis, thrombosis, and non-malignant hematology. METHODS: Multi-institutional study of IM residents at 5 academic training programs in the United States. A 10-question, case-based multiple choice test, with each question accompanied by a 5-point Likert-scale confidence assessment, was distributed electronically. Responses were summarized with frequencies and percentages or medians and ranges, as appropriate. Two sample t-tests or Wilcoxon rank-sum tests were used to compare confidence and knowledge scores. RESULTS: Of 892 IM residents, 174 (19.5%) responded to all questions. Overall, residents answered a median of 7 of 10 questions correctly (range 2-10) and median resident confidence in their responses was 3.1 (on a 5-point scale). Correct responses were significantly associated with higher confidence for all but one question. Having a hematology rotation experience was significantly associated with more correct responses and with higher confidence (p = 0.001 and p<0.001, respectively). CONCLUSIONS: IM residents at several academic hospitals have variable knowledge of ASH-CW guidelines in thrombosis and hemostasis/non-malignant hematology. Residents who have done hematology rotations, particularly a hematology consult rotation, were more likely to answer questions correctly and to be more confident that their answers were correct. Adequate clinical exposure and training in cost-effective care is essential to train clinicians who are cost-conscious in any specialty.
