RESUMO

Purpose: An evidence basis is lacking but needed to compare reading ability outcomes after magnification device training remotely via telerehabilitation versus in office. Methods: A multicenter randomized controlled trial at academic centers and vision rehabilitation private practices randomized 61 visually impaired adults to telerehabilitation or in-office training 1 to 4 months after dispensing new portable electronic, hand-held, or stand optical magnifiers. Telerehabilitation included loaner equipment for Zoom videoconferencing with remote control access software. Using a multilevel regression model, changes in Activity Inventory responses using Rasch analysis estimated reading ability in dimensionless log odds units (logits) (0.14-logit change corresponds with ability change expected from a one-line change in visual acuity). Results: Across 47 participants who completed the trial, reading ability with new magnifiers improved significantly by 0.61 logits on average (95% confidence interval [CI], 0.36-0.86; P < 0.001) from baseline to 1 month, and by an additional 0.44 logits on average (95% CI, 0.19-0.69; P < 0.001) from 1 to 4months (i.e., after magnifier training), with very similar significant findings for both telerehabilitation (n = 29; mean improvement = 0.44 logits; 95% CI, 0.08-0.80; P = 0.018) and in-office training (n = 18; mean improvement = 0.43 logits; 95% CI, 0.15-0.71; P = .003), and no significant difference between randomized groups across both follow-ups (95% CI, -0.43 to 0.61; P = .73). Vision, demographics, and health factors were nonsignificantly related to reading ability changes from 1 to 4 months. Conclusions: Reading ability improved after the provision of newly dispensed magnifiers, with further improvements following additional magnifier training via either telerehabilitation or in-office usual care. Translational Relevance: These findings provide support for the use of telerehabilitation to enhance reading ability with newly prescribed magnifiers as an alternative modality of care delivery.

RESUMO

SIGNIFICANCE: Vision rehabilitation providers tend to recommend handheld, illuminated optical magnifiers for short-duration spot reading tasks, but this study indicates that they are also a viable option to improve sustained, continuous text reading (e.g., books or magazines), especially for visually impaired adults who read slowly with only spectacle-based near correction. PURPOSE: The utility of handheld optical magnifiers for sustained silent reading tasks involving normal-sized continuous text could be a valuable indication that is not recognized by vision rehabilitation providers and patients. METHODS: Handheld, illuminated optical magnifiers were dispensed to 29 visually impaired adults who completed the sustained silent reading test by phone at baseline without the new magnifier and 1 month after using the magnifier. Reading speed in words per minute (wpm) was calculated from the time to read each page and then averaged across up to 10 pages or determined for the fastest read page (maximum). RESULTS: From baseline without the magnifier to 1 month with the magnifier, there was a significant improvement in mean reading speed by 14 wpm (95% confidence interval [CI], 2.6 to 24; P = .02) and for maximum reading speed by 18 wpm (95% CI, 5.4 to 30; P = .005) on average across participants. Participants who had slower baseline reading speeds without the magnifier demonstrated significantly greater improvements in mean and maximum reading speeds on average with the magnifier (95% CI, 8 to 32 [ P = .003]; 95% CI, 4 to 36 [ P = .02]). A significantly greater number of pages were read with the new magnifier than without it (Wilcoxon z = -2.5; P = .01). A significantly greater number of pages were read with the magnifier by participants who read fewer pages at baseline (95% CI, 0.57 to 5.6; P = .02) or had greater improvements in mean reading speed (95% CI, 0.57 to 5.6; P = .007). CONCLUSIONS: Many visually impaired adults read more quickly and/or read a greater number of pages after using a new magnifier for a month than compared to without it. The largest gains occurred among those with more difficulty at baseline, indicating the potential to improve reading rates with magnifiers for those with greater deficits.

RESUMO

The health care sector is a resource-intensive industry, consuming significant amounts of water and energy, and producing a multitude of waste. Health care providers are increasingly implementing strategies to reduce energy use and waste. Little is currently known about existing sustainability strategies and how they may be supported by radiology practices. Here, we review concepts and ideas that minimize energy use and waste, and that can be supported or implemented by radiologists.

RESUMO

Breast cancer recurrence after autologous flap reconstruction is rare and typically occurs at the contact zone between the flap and the native tissue. When a new lesion is found in a reconstructed breast without the characteristic appearance of benign entities such as fat necrosis, definitive tissue diagnosis is often warranted to rule out recurrence or metastasis. Angiolipomas are rare, benign lipomatous tumors that have nonspecific imaging appearances and are thus frequently biopsied or excised for definitive diagnosis. Here, we report a case of a new breast mass found at the contact zone of a reconstructed breast in a patient with a history of ductal carcinoma in situ (DCIS), which was ultimately excised and proven to be an angiolipoma.

RESUMO

Purpose: We examined different methods to reduce the burden of accessing technology for videoconferencing during telerehabilitation for magnification devices for the visually impaired. Methods: During telerehabilitation studies over the past 5 years, vision rehabilitation providers assessed and gave training to visually impaired participants with newly dispensed magnification devices at home who connected to Zoom videoconferencing via loaner tablets or smartphones with assistance from (phase 1; n = 10) investigators by phone, (phase 2; n = 11) local Lions Club volunteers in participants' homes, or (phase 3; n = 24) remote access control software in a randomized controlled trial with 13 usual care controls who received in-office training. All participants completed the same post-telerehabilitation phone survey. Results: A significantly greater proportion of phase 3 subjects indicated they strongly or mostly agreed that the technology did not interfere with the session (96%) compared to phase 1 (60%; 95% confidence interval [CI], 1.2-12.5; P = 0.03) or phase 2 (55%; 95% CI, 1.8-188; P = 0.01). The majority indicated telerehabilitation was as accurate as in person (68%), they were comfortable with telerehabilitation (91%) and interested in a future session (83%), and their magnifier use improved (79%), with no significant differences in these responses between phases (all P > 0.10), including comparisons of participants randomized to telerehabilitation or in-office training in phase 3 who reported similar overall satisfaction levels (P = 0.84). Conclusions: Participants across all phases reported high levels of acceptance for telerehabilitation, with least interference from technology using remote access control in phase 3. Translational Relevance: With accommodations for accessibility to videoconferencing technology, telerehabilitation for magnification devices can be a feasible, acceptable, and valuable option in countries with resources to support the technology.

RESUMO

PURPOSE: To assess the percentage of papillomas from all biopsies performed, comparing differences in patient age and race at a single institution. To assess trends in biopsied papillomas at institutions throughout the United States (US). METHODS: This is a HIPPA-compliant IRB-approved single-institution (Southern1) retrospective review to assess race and age of all-modality-biopsied non-malignant papillomas as a percentage of all biopsies (percentage papillomas calculated as papilloma biopsies/all biopsies) from January 2012 to December 2019. To assess national variation, several academic or large referral centers were contacted to provide data regarding papilloma percentages, biopsy modalities, and trends in case numbers. Trends were estimated using the method of analysis of variance (ANOVA). Comparisons of differences in trends were assessed. RESULTS: Southern1 institution demonstrated a significant association between race and percentage of papillomas (p < 0.0001). After adjustment for multiple comparisons with Bonferroni correction at 5% type I family error, the percentage of biopsied papillomas in Black and Asian patients remained significantly higher than in White patients (p < 0.0001 and p = 0.0032, respectively) using a Chi-square test. The regional variation in percentage of papillomas was found to be 3-9%. Southern1 institution showed a 7-year significant trend of increase in percentage of papillomas. Other institutions showed a decreasing trend (p < 0.05). CONCLUSION: Black and Asian women had significantly higher papilloma percentages compared to white patients in our single institution review. This institution also showed a statistically significant trend of increasing percentage papillomas from 2012 to 2019. Multi-institutional survey found regional variation in percentage papillomas, ranging from 3% to 9%.

RESUMO

OBJECTIVE: To assess how a virtual shadowing (VS) session on breast imaging (BI), shared through social media, can increase interest and awareness of radiology in pre-medical students. METHODS: This study was IRB exempt. A VS slide presentation on BI mentorship, didactic lecture, and deidentified image-rich, case-based learning was created. This session was advertised and presented live through an Instagram page (Pre-Health Virtual Shadowing, @virtualshadowing) geared toward pre-health students. Students were asked to complete a two-question self-assessment using a 5-point Likert scale on which 1 was "least" and 5 was "most." Question 1 read: "Please rate your overall knowledge about radiology and what a radiologist does," and question 2 read: "Please rate your interest in possibly looking into radiology as a potential career." RESULTS: A total of 420 participants logged into the VS session; 82% (345/420) answered the pre-session survey and 48% (202/420) answered the post-session survey. Of post-survey respondents, 84% (170/202) were female and 70% (143/202) were 22 years old or younger. There was a significant difference in mean pre-session survey responses to question 1 when compared to mean post-session survey responses (2.67 vs 3.55, P < 0.001). There was also a significant difference in mean pre-session survey responses to question 2 when compared to mean post-session survey responses (3.16 vs 3.58, P < 0.001). Our VS session remains on YouTube and has 6157 views to date. CONCLUSION: When shared through VS on social media, breast imaging can increase interest and awareness of radiology in pre-medical students.

RESUMO

OBJECTIVE: To determine whether providing a biopsy marker informational handout to patients improves patient knowledge and comfort with receiving a marker. METHODS: In this IRB-exempt prospective study, a patient educational handout on breast biopsy markers was developed. A questionnaire was created with four questions asking patients to self-evaluate their knowledge of biopsy markers and their comfort level with marker placement before and after reading the handout. Technologists distributed the educational handouts to patients presenting for a percutaneous breast biopsy under any modality from December 11, 2020, to April 23, 2021. Data from the completed questionnaires were entered into a database. Statistical analyses included paired t-test and Wilcoxon analyses. RESULTS: In total, 141 completed surveys were included in the analysis. The mean scores prior to reading the handout for knowledge and comfort were 2.59 and 3.40, respectively. After reading the handout, there was a significant increase in mean scores for knowledge and comfort (4.26 and 4.20, respectively) (P < 0.001). There was a 64% increase vs 23% increase for knowledge and comfort, respectively. CONCLUSION: Patient-assessed knowledge of biopsy markers increased significantly after reading our educational handout. Patient-assessed comfort with biopsy marker placement also increased significantly after reading the educational handout, though to a lesser degree than knowledge. Although not included in our study, use of an educational handout may impact patient acceptance of marker placement. Future directions may include quantitatively assessing the effect of the handout on time to consent for a biopsy or influence on acceptance of marker placement.

RESUMO

SIGNIFICANCE: Identification of modifiable barriers to low vision rehabilitation (LVR) can inform efforts to improve practice management of patients with low vision (LV), through, for example, targeted educational programs for optometrists who do not practice LVR. PURPOSE: Mild vision loss (20/25 to 20/70) is increasing in prevalence among the aging population, yet it is unclear whether near-reading complaints (the highest presenting chief complaint) are being addressed. Studies of LVR provision by U.S. optometrists are currently lacking. This study elucidated self-reported optometric practice patterns for patients with mild vision loss. METHODS: Anonymous surveys were completed by 229 actively practicing optometrists across the United States. The survey inquired about the frequency of providing LVR for mild vision loss patients and the top barriers that prevent them from offering LVR management (including optical aids or referral). RESULTS: Compared with those moderately actively practicing LVR, twice as many (2.08×) practitioners who do not practice any LVR reported that they never prescribe near-reading add power of 4 D or greater for mild vision loss (P < .001). Among those who do not practice LVR, 39 and 11% indicated that they never prescribe any LVR management strategies for patients with visual acuity of 20/25 to 20/40 and 20/50 to 20/70, respectively. The two most commonly reported barriers to LVR indicated by about half of respondents were "cost of the LV exam and/or devices" and that "patients are not interested or would not go to an LV exam." Nearly a third of providers reported that "it is not feasible to stock magnifiers in office." CONCLUSIONS: A sizable group of non-LVR providers in the United States may not be addressing the near-vision needs of patients with mild vision loss. Several of the reported top barriers are potentially modifiable through the development of targeted educational programs for providers.

RESUMO

Radiology as a discipline thrives on the dynamic interplay between technological and clinical advances. Progress in almost all facets of the imaging sciences is highly dependent on complex tools sourced from physics, engineering, biology, and the clinical sciences to obtain, process, and view imaging studies. The application of these tools, however, requires broad and deep medical knowledge about disease pathophysiology and its relationship with medical imaging. This relationship between clinical medicine and imaging technology, nurtured and fostered over the past 75 years, has cultivated extraordinarily rich collaborative opportunities between basic scientists, engineers, and physicians. In this review, we attempt to provide a framework to identify both currently successful collaborative ventures and future opportunities for scientific partnership. This invited review is a product of a special working group within the Association of University Radiologists-Radiology Research Alliance.

RESUMO

Ovarian remnant syndrome (ORS) is a rare condition in which ovarian tissue persists at the site of prior oophorectomy and often causes debilitating pelvic pain. Gold standard of treatment is surgical resection. We report a case of persistent ORS in a 44-year-old female who was successfully treated with ovarian artery embolization after failure of standard medical and gynecologic therapies. The ovarian tissue remnant was reduced by 75% in volume, and the patient was near symptom-free four months after the procedure.

RESUMO

OBJECTIVE: To present a method of estimating and equating scales across functional assessment instruments that appropriately represents changes in a patient's functional ability and can be meaningfully mapped to changes in Medicare G-code severity modifiers. DESIGN: Previously published measures of patients' overall visual ability, estimated from low-vision patient responses to 7 different visual function rating scale questionnaires, are equated and mapped onto Medicare G-code severity modifiers. SETTING: Outpatient low-vision rehabilitation clinics. PARTICIPANTS: The analyses presented in this article were performed on raw or summarized low-vision patient ratings of visual function questionnaire (VFQ) items obtained from previously published research studies. INTERVENTIONS: Previously published visual ability measures from Rasch analysis of low-vision patient ratings of items in different VFQs (National Eye Institute Visual Functioning Questionnaire, Index of Visual Functioning, Activities of Daily Vision Scale, Visual Activities Questionnaire) were equated with the Activity Inventory (AI) scale. The 39 items in the Self-Report Assessment of Functional Visual Performance (SRAFVP) and the 48 items in the Veterans Affairs Low Vision Visual Functioning Questionnaire (VA LV VFQ) were paired with similar items in the AI in order to equate the scales. MAIN OUTCOME MEASURES: Tests using different observation methods and indicators cannot be directly compared on the same scale. All test results would have to be transformed to measures of the same functional ability variable on a common scale as described here, before a single measure could be estimated from the multiple measures. RESULTS: Bivariate regression analysis was performed to linearly transform the SRAFVP and VA LV VFQ item measures to the AI item measure scale. The nonlinear relationship between person measures of visual ability on a logit scale and item response raw scores was approximated with a logistic function, and the 2 regression coefficients were estimated for each of the 7 VFQs. These coefficients can be used with the logistic function to estimate functional ability on the same interval scale for each VFQ and for transforming raw VFQ responses to Medicare's G-code severity modifier categories. CONCLUSIONS: The principle of using equated interval scales allows for comparison across measurement instruments of low-vision functional status and outcomes, but can be applied to any area of rehabilitation.

RESUMO

BACKGROUND: Thyroid surgery is associated with low mortality and morbidity and often is performed in an ambulatory setting. The majority of patients undergoing thyroidectomy have an uncomplicated outcome, but common comorbidities may increase mortality and morbidity. Due to low complication rates, studies using single surgeon or single institutional data to identify risk factors for adverse outcomes may be limited by inadequate patient volume. STUDY DESIGN: This retrospective cohort study used data from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). The study group included all thyroidectomy patients over a 6-year period (2005 to 2010). Common patient comorbidities were identified and analyzed using logistic regression. Risk of adverse outcomes was calculated for single and multiple comorbidities. Statistical significance was set at p < 0.05. RESULTS: The study group included 38,577 consecutive patients. Thirty-day mortality and postoperative morbidity were 0.06% and 1.49%, respectively. The risk factors independently associated with morbidity included hypertension, diabetes, advanced age greater than 70 years, COPD, dialysis, malignant thyroid disease, and surgical approach (total thyroidectomy). Substernal thyroidectomy, hypertension, diabetes, age greater than 70 years, COPD, and dialysis were significant predictors (unadjusted) of mortality. Multiple comorbidities resulted in significant cumulative risk. The presence of 3 or more comorbidities was associated with a postoperative morbidity of 5.1% (p < 0.001) and mortality as high as 12.5%. CONCLUSIONS: Thyroid surgery is generally safe. Common comorbidities significantly increase the risk of adverse outcomes and death. Clinically applicable risk calculation based on overall health may improve patient selection, surgical management, and informed consent.

RESUMO

PURPOSE: To characterize functional complaints of new low-vision rehabilitation patients. DESIGN: Prospective observational study. PARTICIPANTS: The Low Vision Rehabilitation Outcomes Study recruited 819 patients between 2008 and 2011 from 28 clinical centers in the United States. METHODS: New patients referred for low-vision rehabilitation were asked, "What are your chief complaints about your vision?" before their appointment. Full patient statements were transcribed as free text. Two methods assessed whether statements indicated difficulty in each of 13 functional categories: (1) assessment by 2 masked clinicians reading the statement, and (2) a computerized search of the text for specific words or word fragments. Logistic regression models were used to predict the influence of age, gender, and visual acuity on the likelihood of reporting a complaint in each functional category. MAIN OUTCOME MEASURES: Prevalence and risk factors for patient concerns within various functional categories. RESULTS: Reading was the most common functional complaint (66.4% of patients). Other functional difficulties expressed by at least 10% of patients included driving (27.8%), using visual assistive equipment (17.5%), mobility (16.3%), performing in-home activities (15.1%), lighting and glare (11.7%), and facial recognition and social interactions (10.3%). Good agreement was noted between the masked clinician graders and the computerized algorithm for categorization of functional complaints (median κ of 0.84 across the 13 categories). Multivariate logistic regression models demonstrated that the likelihood of reading difficulties increased mildly with age (odds ratio, 1.4 per 10-year increment in age; 95% confidence interval, 1.3-1.6), but did not differ with visual acuity (P = 0.09). Additionally, men were more likely to report driving difficulties and difficulties related to lighting, whereas women were more likely to report difficulty with either in-home activities or facial recognition or social interaction (P<0.05 for all). Mobility concerns, defined as walking difficulty and out-of-home activities, showed no relationship to gender, age, or visual acuity. CONCLUSIONS: Reading was the most commonly reported difficulty, regardless of the patient's diagnosis. Neither visual acuity nor gender were predictive of reading concerns, although, age showed a small effect. Addressing reading rehabilitation should be a cornerstone of low-vision therapy.

RESUMO

PURPOSE: To compare low-vision rehabilitation (LVR) clinicians' predictions of the probability of success of LVR with patients' self-reported outcomes after provision of usual outpatient LVR services and to determine if patients' traits influence clinician ratings. METHODS: The Activity Inventory (AI), a self-report visual function questionnaire, was administered pre-and post-LVR to 316 low-vision patients served by 28 LVR centers that participated in a collaborative observational study. The physical component of the Short Form-36, Geriatric Depression Scale, and Telephone Interview for Cognitive Status were also administered pre-LVR to measure physical capability, depression, and cognitive status. After patient evaluation, 38 LVR clinicians estimated the probability of outcome success (POS) using their own criteria. The POS ratings and change in functional ability were used to assess the effects of patients' baseline traits on predicted outcomes. RESULTS: A regression analysis with a hierarchical random-effects model showed no relationship between LVR physician POS estimates and AI-based outcomes. In another analysis, kappa statistics were calculated to determine the probability of agreement between POS and AI-based outcomes for different outcome criteria. Across all comparisons, none of the kappa values were significantly different from 0, which indicates that the rate of agreement is equivalent to chance. In an exploratory analysis, hierarchical mixed-effects regression models show that POS ratings are associated with information about the patient's cognitive functioning and the combination of visual acuity and functional ability, as opposed to visual acuity or functional ability alone. CONCLUSIONS: Clinicians' predictions of LVR outcomes seem to be influenced by knowledge of patients' cognitive functioning and the combination of visual acuity and functional ability-information clinicians acquire from the patient's history and examination. However, clinicians' predictions do not agree with observed changes in functional ability from the patient's perspective; they are no better than chance.

RESUMO

The subdivision of mesodermal cells into muscle and non-muscle cells is crucial to animal development. In the C. elegans postembryonic mesoderm, this subdivision is a result of an asymmetric cell division that leads to the formation of striated body wall muscles and non-muscle coelomocytes. Here we report that the Six homeodomain protein CEH-34 and its cofactor Eyes Absent, EYA-1, function synergistically to promote the non-muscle fate in cells also competent to form muscles. We further show that the asymmetric expression of ceh-34 and eya-1 is regulated by a combination of 1) mesodermal intrinsic factors MAB-5, HLH-1 and FOZI-1, 2) differential POP-1 (TCF/LEF) transcriptional activity along the anterior-posterior axis, and 3) coelomocyte competence factor(s). These factors are conserved in both vertebrates and invertebrates, suggesting a conserved paradigm for mesoderm development in metazoans.
