RESUMEN

Computed tomography (CT) is used as a valuable tool for device selection for interventional therapy in tricuspid regurgitation (TR). We aimed to evaluate predictors of TR reduction using CT and automated deep learning algorithms. Patients with severe to torrential TR and CTs prior to either percutaneous annuloplasty (PA) or tricuspid transcatheter edge-to-edge repair (T-TEER) were enrolled. CTs were analyzed using automated deep learning algorithms to assess tricuspid valve anatomy, right heart morphology, and function. Outcome parameters comprised post-interventional TR ≤ 1 and all-cause mortality. 84 patients with T-TEER (n = 32) or PA treatment (n = 52) were enrolled. Patients with a post-interventional TR ≤ 1 presented lower tenting heights and smaller tenting angles compared to patients with a TR > 1. Tenting height showed the best accuracy for post-interventional TR > 1 with an AUC of 0.756 (95% CI 0.560-0.951) in the T-TEER and 0.658 (95% CI 0.501-0.815) in the PA group, consistent with a suggested threshold of 6.8 mm and 9.2 mm, respectively. Patients with a post-interventional TR ≤ 1 exhibited a mortality of 4% and those with a TR > 1 of 12% during a follow-up of 331 ± 300 and 370 ± 265 days, respectively (p = 0.124). To conclude, tenting is associated with procedural outcomes and should be considered during screening for interventional TR therapy.

RESUMEN

PURPOSE: American Indian/Alaska Native (AI/AN) populations experience significantly higher incidence and mortality rates of cervical cancer. The objective of this systematic scoping review is to characterize the volume and nature of research being conducted specific to the AI/AN population regarding cervical cancer and related clinical themes. METHODS: This scoping review was conducted in collaboration with the Pacific Northwest Evidence-based Practice Center. Search strategies identified eligible publications from 1990 through 4 February 2022. Two reviewers independently abstracted study data, including clinical area, number of participants and percent inclusion of AI/AN, intervention or risk factor, outcomes reported, Indian Health Service (IHS) Region, and funding source. We used published algorithms to assess study design. RESULTS: Database searches identified 300 unique citations. After full-text evaluation of 129 articles, 78 studies and 9 secondary publications were included (total of 87). Approximately 74% of studies were observational in design, with cross-sectional methodology accounting for 42.7% of all included studies. The most common clinical theme was cervical cancer screening. The most common intervention/exposure was risk factor, typically race (AI/AN compared with other groups) (69%). For studies with documented funding sources, 67% were funded by the US Government. CONCLUSION: Of the small number of publications identified, the majority are funded through government agencies, are descriptive and/or cross-sectional studies that are hypothesis generating in nature, and fail to represent the diversity of the AI/AN populations in the US. This systematic scoping review highlights the paucity of rigorous research being conducted in a population suffering from a greater burden of disease.

RESUMEN

OBJECTIVE: We investigated the utility of telehealth instruction versus mail-based written instruction in facilitating high-risk human papillomavirus (hrHPV) self-collection among post-menopausal patients compared with pre-menopausal patients, as well as the impact on acceptability and feasibility. METHODS: We conducted a prospective, randomized study of people eligible for cervical cancer screening, stratified by menopausal status, to undergo standard written or telehealth-based instructions for hrHPV self-collection. English speaking individuals residing in Oregon, with a cervix, eligible for primary hrHPV testing, and with access to a video-capable device were included. Patients with prior hysterectomy, trachelectomy, diagnosis of cervical cancer, or pelvic radiation for gynecologic cancer were excluded. We compared preference for and opinions about self-collection and hrHPV test results, by randomization group and stratified by menopausal status using descriptive statistics. RESULTS: Among 123 patients enrolled, 61 identified as post-menopausal with a median age of 57 years. While the majority of post-menopausal participants who received telehealth instructions found it helpful, only 6.1% considered telehealth instructions necessary to complete self-testing. There was no difference in opinion of telehealth by menopausal status. Overall, 88.5% of post-menopausal participants preferred self-collection to provider-collection. There were no significant differences between pre- and post-menopausal participants in terms of test preference, discomfort, ease of use, or perceptions of self-collection. CONCLUSION: Telehealth instruction did not add significant value to patients participating in hrHPV self-collection, nor did it alter the acceptability of hrHPV-self collection among an English-speaking cohort. Compared with prior experiences with provider-collected screening, hrHPV self-collection was preferred by both pre- and post-menopausal participants. There were no significant differences in preference for provider- versus self-collection when stratified by menopausal status.

RESUMEN

STUDY OBJECTIVE: The objective is to evaluate the rate of sentinel lymph node (SLN) mapping in patients with body mass index (BMI [kg/m2]) BMI ≥ 45 compared with < 45. DESIGN: A retrospective chart review. SETTING: Three urban referral-based settings-1 academic and 2 community based. PATIENTS: Patients age ≥ 18 years, with endometrial intraepithelial neoplasia or clinical stage 1 endometrial cancer who underwent robot-assisted total laparoscopic hysterectomy with attempted SLN mapping between January 2015 and December 2021. INTERVENTIONS: Robot-assisted total laparoscopic hysterectomy with attempted SLN mapping. MEASUREMENTS AND MAIN RESULTS: A total of 933 subjects were included: 795 (85.2%) with BMI < 45 and 138 (14.8%) with BMI ≥ 45. Comparing the BMI < 45 with BMI ≥ 45 group, bilateral mapping was successful in 541 (68.1%) vs 63 (45.7%), respectively. Unilateral mapping was successful in 162 (20.4%) vs 33 (23.9%), respectively. Failure to map occurred in 92 (11.6%) vs 42 (30.4%) (p <.001), respectively. Exploratory analysis also suggested an inverse relationship between success rate of bilateral SLN mapping and BMI, with patients with BMI < 20 having bilateral SLN mapping rates of 86.5% and patients with BMI ≥ 61 having rates of 20.0%. The steepest decline in bilateral SLN mapping rates was from BMI group 46 to 50 compared to 51 to 55, at 55.4% to 37.5%, respectively. Adjusted odds ratio (compared with those with BMI < 30) for those in the BMI 30 to 44 group was 0.36 (95% confidence interval 0.21-0.60) and for those in the BMI ≥ 45 group was 0.10 (95% confidence interval 0.06-0.19). CONCLUSION: There is a statistically significant lower rate of SLN mapping in patients with a BMI ≥ 45 than BMI < 45. Understanding the success of SLN mapping in patients with morbid obesity is essential for preoperative counseling, surgical planning, and developing a risk-appropriate postoperative treatment plan.

RESUMEN

OBJECTIVE: Polymerase chain reaction based human papilloma virus (HPV) self-collection for cervical cancer screening is well established. It is utilized worldwide, accepted by patients, is cost-effective, has comparable sensitivity to provider-collected samples, and increases screening rates, however clinical practice in the United States has not shifted to include HPV self-collection. This study sought to examine provider knowledge and attitudes to better understand why HPV self-collection is not being utilized. METHODS: An observational, qualitative study was conducted. Data were collected with semi-structured focus groups and individual interviews with Oregon healthcare providers. Focus groups and interviews were continued until data saturation was achieved. A grounded theory method was used for analysis, a cyclical process of coding data, memo-writing, and theoretical sampling to the point of saturation. RESULTS: Eighteen healthcare providers participated in the focus group and interviews. They represented 14 of 36 counties across Oregon and 50% were physicians, 33% were nurse practitioners, and 94% worked within family medicine. All providers performed cervical cancer screening according to current American Society for Colposcopy and Cervical Pathology guidelines. Five overarching themes emerged: provider concerns, clinical and provider barriers, patient perspective and barriers, process-based themes, and barriers to cervical cancer screening. Nearly all providers stated they will offer HPV self-collection to most of their patients once available. CONCLUSION: While providers identified concerns and barriers for initiating HPV self-collection, there was a strong desire to implement HPV self-collection and acceptance within patient populations was assumed. Providers indicated the need for HPV self-collection to be incorporated into national screening guidelines along with best practices on how to successfully implement this modality to further increase cervical cancer screening rates.

RESUMEN

PolyADP ribose polymerase inhibitors (PARPi) have transformed the treatment of ovarian cancer. Particularly in high-grade serous ovarian cancer (HGSOC), a disease characterized by homologous recombination deficiency (HRD), PARPi have had a rapid and profound impact on the disease course, as well as biologic and biomarker definitions of HGSOC, thereby creating a paradigm shift in the approach to treatment. In this review, we discuss the role of PARPi in the maintenance treatment of HGSOC, its effect on platinum sensitivity, and cross-resistance between platinum and PARP inhibitors.

RESUMEN

INTRODUCTION: "Long COVID" is a multisystem disease that lasts for 4 or more weeks following initial symptoms of COVID-19. In the UK, at least 10% of patient report symptoms at 12 weeks following a positive COVID-19 test. The aims of this quality improvement survey were to explore patients' acute and post-acute "long" COVID-19 symptoms, their experiences of community services and their recommendations for improving these services. METHODS: Seventy patients diagnosed with COVID were randomly selected from 2 large socially and ethnically diverse primary care practices. Of those contactable by telephone, 85% (41/48) agreed to participate in the quality improvement survey. They were interviewed by telephone using a semi-structured questionnaire about community services for COVID-19 patients. Interviews lasted 10 to 15 minutes. RESULTS: Forty-nine percent of patients reported at least 1 post-acute COVID-19 symptom. The most common were severe fatigue (45%), breathlessness (30%), neurocognitive difficulties (such as poor memory), poor concentration and "brain fog" (30%), headaches (20%), and joint pain (20%). Many patients felt isolated and fearful, with scant information about community resources and little safety netting advice. Patients also expected more from primary care with over half (56%) recommending regular phone calls and follow up from healthcare staff as the most important approach in their recovery. CONCLUSIONS: In line with patients' requests for more support, the practices now routinely refer patients with long COVID to an on-site social prescriber who explores how they are getting on, refers them to the GP or practice nurse when required, and sign posts them to support services in the community.

RESUMEN

Exposure to environmental trace elements has been studied in relation to many cancers. However, an association between exposure to trace elements and skin cancer remains less understood. Therefore, we conducted a systematic review of published epidemiologic literature examining the association between exposure to trace elements, and risk of melanoma and keratinocyte carcinoma in humans. We identified epidemiologic studies investigating exposure to arsenic, cadmium, chromium, copper, iron, selenium, and zinc and risk of skin cancer in humans. Among the minerals, arsenic, selenium, and zinc had more than five studies available. Exposure to arsenic was associated with increased risk of keratinocyte carcinoma, while too few studies existed on melanoma to draw conclusions. Exposure to selenium was associated with possible increased risk of keratinocyte carcinoma. Studies of zinc and skin cancer were case-control in design and were found to have inconsistent associations. The data on the association between cadmium, chromium, copper, and iron and risk of skin cancer remain too sparse to draw any conclusions. In summary, epidemiologic studies on exposure to trace elements and cutaneous malignancies are limited. Studies with larger sample sizes and prospective designs are warranted to improve our knowledge of trace elements and skin cancer.
