RESUMO

Advancing the well-being of individuals living with HIV necessitates attention to social determinants of health, including food insecurity. Through a clinical and community-based needs assessment, we aimed to gain insight into experiences of food insecurity among patients receiving care at a large pediatric HIV outpatient clinic in the Southeastern United States. We adopted a multimodal assessment approach involving a literature review, community profiling, key informant interviews, focus group discussions with staff, patients and parents and a community stakeholder advisory meeting. Our needs assessment demonstrates that food insecurity is an important aspect of the lived experience of children, adolescents and young adults living with HIV. Clinical staff agreed that food insecurity screening should be incorporated into the patient care workflow but ideally only in concert with providing resources that meet their needs. We formulated a recommendation matrix for addressing food insecurity based on priority importance and feasibility. Collaborative relationships between healthcare practitioners and leaders, community-based organizations and local and federal funding sources are vital for enhancing patients' access to sustainable, reliable solutions to this fundamental determinant of health. Our approach provides a tested model for other clinics seeking to identify and alleviate food insecurity among patients.

RESUMO

Interferon-induced ubiquitin (Ub)-like modifier ISG15 covalently modifies host and viral proteins to restrict viral infections. Its function is counteracted by the canonical deISGylase USP18 or Ub-specific protease 18. Notwithstanding indications for the existence of other ISG15 cross-reactive proteases, these remain to be identified. Here, we identify deubiquitinase USP16 as an ISG15 cross-reactive protease by means of ISG15 activity-based profiling. Recombinant USP16 cleaved pro-ISG15 and ISG15 isopeptide-linked model substrates in vitro, as well as ISGylated substrates from cell lysates. Moreover, interferon-induced stimulation of ISGylation was increased by depletion of USP16. The USP16-dependent ISG15 interactome indicated that the deISGylating function of USP16 may regulate metabolic pathways. Targeted enzymes include malate dehydrogenase, cytoplasmic superoxide dismutase 1, fructose-bisphosphate aldolase A, and cytoplasmic glutamic-oxaloacetic transaminase 1. USP16 may thus contribute to the regulation of a subset of metabolism-related proteins during type-I interferon responses.

RESUMO

BACKGROUND: Although patient advocates have developed templates for standard consent forms, evaluating patient preferences for first in human (FIH) and window of opportunity (Window) trial consent forms is critical due to their unique risks. FIH trials are the initial use of a novel compound in study participants. In contrast, Window trials give an investigational agent over a fixed duration to treatment naïve patients in the time between diagnosis and standard of care (SOC) surgery. Our goal was to determine the patient-preferred presentation of important information in consent forms for these trials. METHODS: The study consisted of two phases: (1) analyses of oncology FIH and Window consents; (2) interviews of trial participants. FIH consent forms were analyzed for the location(s) of information stating that the study drug has not been tested in humans (FIH information); Window consents were analyzed for the location(s) of information stating the trial may delay SOC surgery (delay information). Participants were asked about their preferred placement of the information in their own trial's consent form. The location of information in the consent forms was compared to the participants' suggestions for placement. RESULTS: 34 [17 FIH; 17 Window] of 42(81%) cancer patients approached participated. 25 consents [20 FIH; 5 Window] were analyzed. 19/20 FIH consent forms included FIH information, and 4/5 Window consent forms included delay information. 19/20(95%) FIH consent forms contained FIH information in the risks section 12/17(71%) patients preferred the same. Fourteen (82%) patients wanted FIH information in the purpose, but only 5(25%) consents mentioned it there. 9/17(53%) Window patients preferred delay information to be located early in the consent, before the "Risks" section.  3/5(60%) consents did this. CONCLUSIONS: Designing consents that reflect patient preferences more accurately is essential for ethical informed consent; however, a one-size fits all approach will not accurately capture patient preferences. We found that preferences differed for FIH and Window trial consents, though for both, patients preferred key risk information early in the consent. Next steps include determining if FIH and Window consent templates improve understanding.

RESUMO

A 26-year-old male presented with a 2-year history of a hyperkeratotic growth from the left index finger. Histopathology was consistent with an acquired digital fibrokeratoma with changes of a pleomorphic fibroma. Lesional cells were negative for CD34, Rb, and p53, and were positive for FXIIIa. We introduce the pleomorphic acquired digital fibrokeratoma as a novel clinicopathologic entity.

RESUMO

In this article, we discuss the impact of the COVID-19 pandemic on various areas of global health dermatology, including patient care, neglected tropical diseases, education, and collaborations. Information was collected from literature review and informal interviews with more than 20 dermatologists from around the world. Many of the setbacks and hardships experienced by the global health community in the last year highlight long-standing global interdependencies and systems that perpetuate ethnic, economic, and social inequalities on local and global scales. The pandemic has brought discussions on global health colonialism and domestic health inequality to the forefront.

RESUMO

BACKGROUND: It is critical patients understand the terms used to describe oncology treatments; however, even basic chemotherapy terminology can be misunderstood. Rural communities tend to have especially low levels of health literacy compared with nonrural communities. To address low health literacy in rural communities, this study tested rural participants' understanding of previously developed educational chemotherapy videos that were designed for an underserved urban population. Participants were also asked for feedback to determine if the videos could be improved. METHODS: Fifty English-speaking patients who reside in counties classified as rural according to the Rural-Urban Continuum Code designations (RUCC 4-9) participated in the study. Participants were asked to define 6 chemotherapy terms before and after viewing a short, animated video explaining the term in English. Rates of correct and incorrect definitions provided by participants were also compared with previously published results from an urban cohort. RESULTS: All participants had statistically significantly higher rates of correct definitions for all 6 terms following the video intervention. Palliative chemotherapy understanding improved the most (10% correct prevideo and 76% postvideo intervention). For each video, the majority of participants (77%-92%) suggested no changes to the videos. CONCLUSION: Given the prevalence of low health literacy in rural communities, it is important to have effective educational interventions to improve the understanding of basic oncology-treatment terminology. This study found that short, educational videos, originally designed for an underserved urban population, can significantly improve understanding of commonly misunderstood chemotherapy terminology in a rural setting as well. LAY SUMMARY: Chemotherapy terminology can be confusing to patients. Understanding can be especially difficult in areas with low health literacy, such as underserved urban and rural communities. To address this concern, previously developed short, animated videos describing basic chemotherapy terminology were found to improve patient understanding in an underserved urban setting. In this study, the videos were tested in a rural population and their effectiveness was established. Participants in the rural setting were significantly more likely to correctly define all 6 tested terms after watching the videos. Educational tools for high-need populations are essential to ensure patients can understand the treatment they receive.

RESUMO

PURPOSE: To assess TNM 8 staging in discriminating overall survival (OS) amongst patients with locally advanced oral cavity squamous cell carcinoma (OCSCC) treated with surgery and post-operative radiotherapy (PORT), compared to TNM 7. MATERIAL AND METHODS: Data from OCSCC patients treated with surgery and PORT between January 2010 and December 2018 were reviewed. Demographics, tumour characteristics and treatment response data were collected, and patients staged according to both TNM 7 and TNM 8. OS and disease free survival (DFS) were estimated using the Kaplan Meier method. Univariate and multivariable analyses were conducted for factors affecting OS, DFS and early disease recurrence within 12 months. RESULTS: Overall 172 patients were analyzed. Median follow up was 32 months for all patients and 48 months for surviving patients. TNM 8 staging demonstrated significant stratification of OS and DFS amongst the entire cohort, whereas TNM 7 staging did not. On multivariable analysis, TNM 8 stage, performance status (PS) and a positive surgical margin were prognostic for OS. Looking at disease recurrence within 12 months, TNM 8 stage IVB, presence of lymphovascular invasion (LVSI), younger age and lesser smoking history were predictive factors on multivariable analysis. CONCLUSION: TNM 8 is a good development of its predecessor in terms of predicting survival for patients with locally advanced OCSCC. We have also identified younger age (<60 years) and a smoking history of <10 pack years as risk factors for early disease recurrence, potentially representing a separate biological cohort within OCSCC patients.

RESUMO

PURPOSE: The publicly available Society for Adolescent Health and Medicine (SAHM) Resident Curriculum provides resources for blended learning. This report presents a formal evaluation of this blended learning curriculum. METHODS: We adapted the SAHM curriculum for a required four-week rotation for pediatricians in training. We selected webinars, videos, articles, and Web sites from the SAHM curriculum to complement the local clinical context. We evaluated the effectiveness of our curriculum using resident pre- and post-self-assessments, weekly knowledge quizzes, and a standardized patient encounter. RESULTS: Resident self-assessment improved in all domains except managing urologic conditions. Residents scored 85% or higher on knowledge quizzes. Standardized patients rated residents a mean of 90.2 out of 100 on adolescent communication and 89.0 out of 100 on parent communication. CONCLUSIONS: A blended learning curriculum consisting of SAHM online materials and local clinical experiences improved resident self-assessment, knowledge, and communication skills.

RESUMO

BACKGROUND: Interferon (IFN) signalling pathways, a key element of the innate immune response, contribute to resistance to conventional chemotherapy, radiotherapy, and immunotherapy, and are often deregulated in cancer. The deubiquitylating enzyme USP18 is a major negative regulator of the IFN signalling cascade and is the predominant human protease that cleaves ISG15, a ubiquitin-like protein tightly regulated in the context of innate immunity, from its modified substrate proteins in vivo. METHODS: In this study, using advanced proteomic techniques, we have significantly expanded the USP18-dependent ISGylome and proteome in a chronic myeloid leukaemia (CML)-derived cell line. USP18-dependent effects were explored further in CML and colorectal carcinoma cellular models. RESULTS: Novel ISGylation targets were characterised that modulate the sensing of innate ligands, antigen presentation and secretion of cytokines. Consequently, CML USP18-deficient cells are more antigenic, driving increased activation of cytotoxic T lymphocytes (CTLs) and are more susceptible to irradiation. CONCLUSIONS: Our results provide strong evidence for USP18 in regulating antigenicity and radiosensitivity, highlighting its potential as a cancer target.

RESUMO

BACKGROUND: The prevalence of infections due to nontuberculous mycobacteria (NTM) is increasing worldwide, yet little is known about the epidemiology and pathophysiology of these ubiquitous environmental organisms. Pulmonary disease due to Mycobacterium avium complex is most prevalent, but many other NTM species can cause disease in virtually any organ system. As NTM becomes an increasingly common cause of morbidity and mortality, more information is needed about the epidemiology of NTM disease. METHODS: We conducted a retrospective chart review of all patients with cultures that grew NTM at a Midwestern tertiary hospital from 1996 to 2017. Information on demographics, medical history, clinical findings, treatment, and outcome was obtained from medical records of all NTM isolates. American Thoracic Society/Infectious Diseases Society of America criteria were used to define pulmonary NTM infections. RESULTS: We identified 1064 NTM isolates, 365 of which met criteria for NTM infection. Pulmonary cases predominated (185 of 365; 50.7%), followed by skin/soft tissue (56 of 365; 15.3%), disseminated (40 of 365; 11%), and lymphatic (28 of 365; 7.7%) disease. Mycobacterium avium complex was the most common species (184 of 365; 50.4%). Individuals aged >50 years were most affected (207 of 365; 56.7%). Common comorbidities included structural lung disease (116 of 365; 31.8%), use of immunosuppressive medications (78 of 365; 21.4%), malignancy (59 of 365; 16.2%), and human immunodeficiency virus (42 of 365; 11.5%). CONCLUSIONS: This large cohort provides information on the demographics, risk factors, and disease course of patients with pulmonary and extrapulmonary NTM infections. Most patients had medical comorbidities that resulted in anatomic, genetic, or immunologic risk factors for NTM infection. Further population-based studies and increased disease surveillance are warranted to further characterize NTM infection prevalence and trends.

RESUMO

Introduction: The problems associated with recruitment and retention of patients in clinical trials have been widely addressed in literature; however, similar problems associated with healthcare workers are rarely reported. The aim of this paper is to outline the factors that can impede a participant's successful participation in a research project and to analyse the characteristics of participants that withdrew. Methods: The Laparoscopic Simulation Skills Program (LSSP) was a prospective randomised cohort study investigating the efficacy of self-directed learning for basic laparoscopic skills acquisition. Two hundred and seven medical students, junior doctors, as well as surgical and gynaecology trainees were enrolled between June 2015 and November 2016. Results: Fifty-six (27%) participants failed to attend the final assessment. Of these, 43 participants (77%) responded to the follow-up survey and/or phone contact regarding non-attendance. Most participants failed to attend due to lack of free time/conflicting clinical duties and university requirements. Participants who did not attend the final assessment and did not provide further responses were less motivated by a career in surgery, surgical simulation and perceived less benefits of laparoscopic simulation. The 43 participants who answered the survey and/or phone contact provided similar responses to the participants who completed the study requirements and had more intrinsic motivators to enrol. Conclusions: Clinical duties and other educational commitments are the biggest barriers to participation in simulation based-education research.
