RESUMEN

BACKGROUND/OBJECTIVES: The use of mobile ophthalmology applications (MOA) is increasing, but many of these tools have not been validated. This study was performed to assess the accuracy of a popular MOA, Eye Handbook, in measuring five commonly-tested vision assessment parameters (distance visual acuity (DVA), near visual acuity (NVA), colour vision testing (CVT), contrast sensitivity (CS), and pupillary distance (PD)) was compared with traditional vision assessment methods (TVAM) [i.e. Snellen chart, Rosenbaum near card, Ishihara, Pelli Robson test, etc.] performed in the eye clinic setting. SUBJECTS/METHODS: Prospective crossover clinical trial of 129 patients meeting inclusion criteria. RESULTS: Participants averaged significantly better DVA (p = 0.0008), NVA (p < 0.0001), and CVT (p = 0.0105) in the MOA than the TVAM, but all three MOA assessments were predictive of the TVAM values. CS was significantly better with the MOA (p < 0.0001). Linear regression and Spearman correlation tests were applied to assess the effect of CS on NVA, which showed no clear relationship between the difference in NVA and the difference in CS. PD using the two methods was in agreement with no significant difference (p = 0.2889). CONCLUSION: The studied MOA offers an effective means of measuring four common vision parameters: DVA, NVA, CVT, and PD. The MOA can potentially be used by eye care providers, health care providers, and patients, both as a screening tool with correction factor and to monitor ocular pathologies. Atypical MOA measurements should prompt testing in the clinic with formal TVAMs.

RESUMEN

PURPOSE: Collaboration in the field of speech-language pathology occurs across a variety of digital devices and can entail the usage of multiple software tools, systems, file formats, and even programming languages. Unfortunately, gaps between the laboratory, clinic, and classroom can emerge in part because of siloing of data and workflows, as well as the digital divide between users. The purpose of this tutorial is to present the Collaboverse, a web-based collaborative system that unifies these domains, and describe the application of this tool to common tasks in speech-language pathology. In addition, we demonstrate its utility in machine learning (ML) applications. METHOD: This tutorial outlines key concepts in the digital divide, data management, distributed computing, and ML. It introduces the Collaboverse workspace for researchers, clinicians, and educators in speech-language pathology who wish to improve their collaborative network and leverage advanced computation abilities. It also details an ML approach to prosodic analysis. CONCLUSIONS: The Collaboverse shows promise in narrowing the digital divide and is capable of generating clinically relevant data, specifically in the area of prosody, whose computational complexity has limited widespread analysis in research and clinic alike. In addition, it includes an augmentative and alternative communication app allowing visual, nontextual communication.

RESUMEN

PURPOSE: To determine roles of patient history, donor tissue characteristics, tissue preparation methods, and surgeon technique for graft detachment requiring rebubbling after Descemet stripping automated endothelial keratoplasty (DSAEK) and Descemet membrane endothelial keratoplasty (DMEK) procedures. METHODS: Retrospective analysis of all eyes undergoing first-time DSAEK or DMEK at the study institution between 2013 and 2022. Data were collected regarding recipients' history, donors' medical history, tissue preparation methods, intraoperative details, and postoperative clinical outcomes. Multivariate statistical analysis was conducted to identify risk factors for graft detachment necessitating rebubbling. RESULTS: Of 1240 eyes meeting inclusion criteria, 746 (60.2%) underwent DSAEK, and 494 (39.8%) underwent DMEK. DSAEK procedures had 12.5% rebubbling rate, whereas DMEK procedures had 18.4% rebubbling rate (P = 0.005). Sub50-DSAEK (<50 µm) grafts had 16.0% rebubble rate, whereas sub100-DSAEK (51-99 µm) and >100 µm DSAEKs had rebubble rate of 9.9% and 9.5%, respectively (P = 0.006). Significant risk factors for DSAEK graft detachment included history of retinal surgery (OR = 2.59), preloaded tissue (OR = 2.70), forceps insertion (OR = 2.33), use of sub50-DSAEK lenticules versus sub100-DSAEK (OR = 2.44) and >100 µm DSAEK (OR = 2.38) lenticules, and donor history of noninsulin-dependent diabetes mellitus (OR = 4.18). DMEK risk factors included recipient history of cancer (OR = 2.51) and use of higher SF6 gas concentration (OR = 1.09). Although rebubbled DMEK eyes had comparable refractive outcomes to nonrebubbled eyes (P >0.05), rebubbled DSAEK eyes had worse refractive outcomes at all time points (P < 0.05). CONCLUSIONS: Graft detachments in DSAEK and DMEK are influenced by various factors, including donor tissue characteristics, tissue preparation, and surgical technique. Identifying and understanding these factors can potentially improve postoperative outcomes.

RESUMEN

Trauma is a leading cause of death in the United States for people under 45. Amongst trauma-related injuries, orthopedic injuries represent a significant component of trauma-related morbidity. In addition to the potential morbidity and mortality secondary to the specific traumatic injury or injuries sustained, sepsis is a significant cause of morbidity and mortality in trauma patients as well, and infection related to orthopedic trauma can be especially devastating. Therefore, infection prevention and early recognition of infections is crucial to lowering morbidity and mortality in trauma. Risk factors for fracture-related infection include obesity, tobacco use, open fracture, and need for flap coverage, as well as fracture of the tibia and the degree of contamination. Timely administration of prophylactic antibiotics for patients presenting with open fractures has been shown to decrease the risk of fracture-related infection, and in patients that do experience sepsis from an orthopedic injury, prompt source control is critical, which may include the removal of implanted hardware in infections that occur more than 6 weeks from operative fixation. Given that orthopedic injury constitutes a significant proportion of traumatic injuries, and will likely continue to increase in number in the future, surgeons caring for patients with orthopedic trauma must be able to promptly recognize and manage sepsis secondary to orthopedic injury.

RESUMEN

Background: Despite the high prevalence of post-operative fever, a variety of approaches are taken as to the components of a fever evaluation, when it should be undertaken, and when empiric antibiotic agents should be started. Hypothesis: There is a lack of consensus surrounding many common components of a post-operative fever evaluation. Patients and Methods: The Surgical Infection Society membership was surveyed to determine practices surrounding evaluation of post-operative fever. Eight scenarios were posed in febrile (38.5°C), post-operative general surgery or trauma patients, with 19 possible components of work-up (physical examination, complete blood count [CBC], fungal biomarkers, lactate and procalcitonin [PCT] concentrations, cultures, imaging) and management (antibiotic agents). Each scenario was then re-considered for intensive care unit (ICU) patients (intubated/unstable hemodynamics). Agreement on a parameter (<1/4 or >3/4 of respondents) achieved consensus, positive or negative. Parameters between had equipoise; α was set at 0.05. Results: Among the examined scenarios, only CBC and physical examination received positive consensus across most scenarios. Blood/urine cultures, imaging, lactate, inflammatory biomarkers, and the empiric administration of antibiotic agents did not reach consensus; support was variable depending on the clinical scenario, illness severity, and the individual preferences of the answering clinician. The qualitative portion of the survey identified "fever threshold and duration," "clinical suspicion," and "physiologic manifestation" as the most important factors for deciding about the initiation of a fever evaluation and the potential empiric administration of antibiotic agents. Conclusions: There is consensus only for physical and examination routine laboratory work when initiating the evaluation of febrile post-operative patients. However, there are multiple components of a fever evaluation that individual respondents would select depending on the clinical scenario and severity of illness. Parameters demonstrating equipoise are potential candidates for formal guidance or pragmatic prospective trials.

RESUMEN

Social media (e.g., TikTok) challenge is a relatively new phenomenon wherein a user creates and posts videos performing an often-dangerous task. The ease of access and availability of social media in recent times make teens and young adults susceptible to these viral Internet challenges and accidental injury. The severity, morbidity, and mortality of burn injuries from social media challenges have not readily been documented in the medical literature. In this brief report, we present three cases of accidental burns after attempting social media challenges involving boiling water or flame. The injuries ranged from superficial partial thickness burns to 24% total body surface area (TBSA) full thickness burns. Online challenges show the potential for severe injury and disability and underlie the importance of awareness and education of the public, further research into the usage of TikTok and other media platforms, and early referral to the American Burn Association recognized center.

RESUMEN

Background: There is little guidance regarding empiric therapy for superficial surgical site infections (SSIs). Management of incisions with signs of SSI lacks consensus and management is variable among individual surgeons. Methods: The Surgical Infection Society was surveyed regarding management of SSIs. Cases were provided with varying wound descriptions, initial wound class (WC), post-operative day, and presence of a prosthesis. Responses were in multiple-choice format; statistics: χ2; α = 0.05. Results: Seventy-eight members responded. For appearance scenarios, respondents believed that both mild erythema (55%) and clear drainage (64%) could be observed, whereas substantial (>3 cm) erythema or purulence should be treated with complete (22% and 50%) or partial (55% and 40%) opening of the incision. Degree of erythema did not influence administration of antibiotic agents, but purulence was more likely than clear drainage to be treated with antibiotics (38% vs. 6%; p < 0.001). There were no differences based on WC, except that clean cases were more likely than higher WC scenarios to be treated with gram-positive coverage alone (WC 1 [26%] vs. 2 [10%] vs. 3 [13%] vs. 4 [4%]; p < 0.001). Post-operative day (POD) three appeared to be an inflection point for more aggressive treatment of suspected incisional SSI, with fewer (POD 0 [86%] vs. POD day 3 [54%]; p < 0.001) reporting observation. Respondents were more likely to obtain imaging, start broad-spectrum antibiotic agents, and return to the operating room for purulence in the presence of a mesh. Conclusions: Presented with escalating possibility of SSI, respondents reported lower rates of observation, increased use of antibiotic agents, and increased surgical drainage. Many scenarios lack consensus regarding appropriate therapy. The complete elimination of SSIs is unlikely to be accomplished soon, and this study provides a framework for understanding how surgeons approach SSIs, and potential areas for further research or pragmatic guidance.

RESUMEN

Background: Many techniques for closure of surgical incisions are available to the surgeon, but there is minimal guidance regarding which technique(s) should be utilized at the conclusion of surgery and under what circumstances. Hypothesis: Management of incisions at the conclusion of surgery lacks consensus and varies among individual surgeons. Methods: The Surgical Infection Society membership was surveyed on the management of incisions at the conclusion of surgery. Several case scenarios were provided to test the influences of operation type, intra-operative contamination, and hemodynamic stability on incision management (e.g., close fascia or skin, use of incision/wound vacuum-assisted closure [VAC] device). Responses by two-thirds of participants were required to achieve consensus. Data analysis by χ2 test and logistic regression, a = 0.05. Response heterogeneity was quantified by the Shannon index (SI). Results: Among 78 respondents, consensus was achieved for elective splenectomy (91% close skin/dry dressing). Open appendectomy and left colectomy/end-colostomy had the greatest heterogeneity (SI, 1.68 and 1.63, respectively). During trauma laparotomy, the majority used damage control for hemodynamic instability (53%-67%) but not for hemodynamically stable patients (0%-1.3%; p < 0.001). Additional consensus was achieved for close skin/dry dressing for hemodynamically stable trauma splenectomy patients (87%) and fascia open/wound VAC for hemodynamically unstable colon resection/anastomosis (67%). Fecal diversion for rectal injury and colon resection/anastomosis (both when hemodynamically stable) had high heterogeneity (SI, 1.56 and 1.48, respectively). In penetrating trauma, sentiment was for more use of wet-to-dry dressings and incision/wound VAC with increased contamination in hemodynamically stable patients. Conclusions: Damage control was favored in hemodynamically unstable trauma patients, with use of wet-to-dry dressings and incision/wound VAC with spillage after penetrating trauma. However, most scenarios did not achieve consensus. High variability of practices regarding incision management at the conclusion of surgery was confirmed. Prospective studies and evidence-based guidance are needed to guide decision making at end-operation.

RESUMEN

PURPOSE: To compare subjective and objective dry eye syndrome (DES) metrics preoperatively and postoperatively in patients undergoing bilateral upper eyelid blepharoplasty (ULB) using orbicularis-sparing versus orbicularis-excising techniques. METHODS: A double-blind, randomized clinical trial was conducted on patients without prior DES or other severe conditions who presented to our institution between 2017 and 2019 for routine functional ULB. Patients were randomized into two treatment arms: bilateral ULB using the orbicularis-sparing technique or bilateral ULB using the orbicularis-excising technique. One subjective and seven objective DES assessments were performed on all patients preoperatively and 1 month and 1 year after surgery. RESULTS: A total of 63 patients were recruited for the study. Standard Patient Evaluation of Eye Dryness (SPEED) scores decreased in both treatment groups at 1 month and 1 year postoperatively. This change did not significantly vary based on surgical technique. Objective DES assessments were not significantly changed at both postoperative time points for either group. There was a correlation between the severity of preoperative DES symptoms and the subjective improvement of DES symptoms postoperatively in both groups. CONCLUSIONS: ULB with an orbicularis-sparing or orbicularis-excising technique does not worsen subjective or objective DES metrics and so, surgeons may confidently use either surgical technique. These findings may impact postoperative expectations for surgeons and patients alike.

RESUMEN

INTRODUCTION: SPEAK-OUT!® is a behavioral treatment for hypokinetic dysarthria in persons with Parkinson's disease (PD) that has become an alternative to the gold-standard Lee Silverman Voice Treatment (LSVT) in recent years. Acoustic evaluation of the efficacy of SPEAK-OUT!® therapy has focused on prosody. The purpose of this study was to investigate SPEAK-OUT!® efficacy in terms of vocal quality and its impact on quality of life. Vocal quality was measured acoustically using cepstral peak prominence (CPP) analysis and the Acoustic Voice Quality Index (AVQI) and perceptually using clinical ratings of speech performance. Impact on quality of life was measured with the Voice Handicap Index (VHI) and Voice-Related Quality of Life (V-RQOL). An additional goal of this study was to investigate whether dysarthria severity and disease duration were predictive of changes in voice quality due to SPEAK-OUT!®. METHODS: Pre- and post-therapy data included PD participants' acoustic and perceptual ratings of audio recordings. Demographic data included age, sex, diagnosis, duration of PD, and severity of dysarthria. RESULTS: Participants achieved significant improvement in the vowel and sentence CPP smoothed (CPPS) mean score as well as in their AVQI score post SPEAK-OUT!® treatment. Improvements in AVQI correlated negatively with disease duration and positively with dysarthria severity. DISCUSSION/CONCLUSION: SPEAK-OUT!® is effective in improving voice quality in patients with hypokinetic dysarthria due to idiopathic PD. Patients with more severe dysarthria and with a shorter disease duration may benefit the most, supporting earlier intervention. As for the type of measurement, AVQI combines acoustics from both vowel and sentence contexts and may therefore be the measure of choice over CPPS (vowel) or CPPS (sentence).

RESUMEN

Background: Surgical stabilization of rib fractures is recommended in patients with flail chest or multiple displaced rib fractures with physiologic compromise. Surgical stabilization of rib fractures (SSRF) and surgical stabilization of sternal fractures (SSSF) involve open reduction and internal fixation of fractures with a plate construct to restore anatomic alignment. Most plate constructs are composed of titanium and presence of this foreign, non-absorbable material presents opportunity for implant infection. Although implant infection rates after SSRF and SSSF are low, they present a challenging clinical entity often requiring prolonged antibiotic therapy, debridement, and potentially implant removal. Methods: The Surgical Infection Society's Therapeutics and Guidelines Committee and Chest Wall Injury Society's Publication Committee convened to develop recommendations for antibiotic use during and after surgical stabilization of traumatic rib and sternal fractures. Clinical scenarios included patients with concomitant infectious processes (sepsis, pneumonia, empyema, cellulitis) or sources of contamination (open chest, gross contamination) incurred as a result of their trauma and present at the time of their surgical stabilization. PubMed, Embase, and Cochrane databases were searched for pertinent studies. Using a process of iterative consensus, all committee members voted to accept or reject each recommendation. Results: For patients undergoing SSRF or SSSF in the absence of pre-existing infectious process, there is insufficient evidence to suggest existing peri-operative guidelines or recommendations are inadequate. For patients undergoing SSRF or SSSF in the presence of sepsis, pneumonia, or an empyema, there is insufficient evidence to provide recommendations on duration and choice of antibiotic. This decision may be informed by existing guidelines for the concomitant infection. For patients undergoing SSRF or SSSF with an open or contaminated chest there is insufficient evidence to provide specific antibiotic recommendations. Conclusions: This guideline document summarizes the current Surgical Infection Society and Chest Wall Injury Society recommendations regarding antibiotic use during and after surgical stabilization of traumatic rib or sternal fractures. Limited evidence exists in the chest wall surgical stabilization literature and further studies should be performed to delineate risk of implant infection among patients undergoing SSSRF or SSSF with concomitant infectious processes.

RESUMEN

PURPOSE: The Motor Planning Theory of Prosody and reading prosody research indicate that "out of the blue" oral reading, as practiced in clinical and research settings, invokes surface rather than covert prosody, particularly when readers are recorded, less skilled, and/or speech impaired. Warm-up is not considered in passage reading for motor-speech assessment. We report on a preliminary study aimed to investigate the effect of warm-up on reading prosody in two conditions: silent reading alone and reading "out of the blue" followed by silent reading. A secondary aim of the study was to examine the effect of reading skill on reading prosody. METHOD: Twenty-one monolingual, English-speaking volunteers were recorded reading the My Grandfather Passage (GP) while their eye movements were tracked. Participants were randomly assigned to one of two reading conditions: (a) silent-oral (SO) and (b) oral-silent-oral (OSO). In the SO condition, participants read the GP silently as a warm-up for the subsequent oral reading. In the OSO condition, participants first read the GP aloud ("out of the blue") and then read the same passage silently with the instruction to do this in preparation for a second oral reading. Reading skill was quantified using eye-voice span and Wide Range Achievement Test-Fourth Edition testing. Reading prosody was evaluated using pause indexes, the Acoustic Multidimensional Prosody Index, and speech rate. CONCLUSIONS: One oral reading before a silent reading but not a silent reading alone before oral reading was shown to affect reading prosody. In terms of reading skill, results indicate that predictive associations patterned differently in the reading conditions explored, suggesting different underlying skill sets.

RESUMEN

Whole-body cryotherapy involves the use of a specially designed liquid nitrogen cryochamber to expose the body to cold, dry air (below -100°C) for short periods of time and has been gaining popularity in the field of sports and exercise science as an aid in recovery following exercise or injury. While proponents of cryotherapy claim that it can reduce inflammation and expedite muscle recovery, there has yet to be published literature that supports these claims. While there is no evidence that cryotherapy provides any benefits, there is a risk for injury with the use of these devices owing to the extreme cold temperatures that are used. We present the three cases of patients who suffered frostbite injuries secondary to single cryotherapy sessions. The first case involved a 26-year-old male who suffered a full-thickness frostbite injury that eventually required excision and grafting, while cases 2 and 3 involve a 17-year-old male and a 28-year-old male who both suffered partial-thickness injuries.

RESUMEN

PURPOSE: To explore surgeons' perspectives and practice patterns in gray area surgical complications (GASCs) within cataract surgery. SETTING: Tertiary care academic referral center. DESIGN: Retrospective observational cross-sectional study. METHODS: An anonymous, online survey consisting of 11 potential intraoperative GASC scenarios was developed and distributed to practicing and resident ophthalmologists in the U.S. Demographic data such as gender, experience, and practice settings were recorded. Using a Likert scale, respondents scaled their perception of likelihood that a GASC could lead to postoperative complications and their obligation toward patient disclosure and documentation in the operative report. Respondents also scaled their likelihood of agreement with a series of statements inserted to assess baseline anxiety levels and inherent perspectives regarding disclosure. RESULTS: 389 responses were analyzed. Female surgeons were more likely than male surgeons to disclose GASCs to their patients and experience psychological anxiety regarding patient outcomes. Both early- and late-stage residents were more likely to believe that GASCs could lead to vision-limiting outcomes when compared with attending surgeons. Surgeons at academic centers were more likely than community-based surgeons to disclose GASCs in the operative report and experience psychological anxiety regarding patient outcomes. CONCLUSIONS: Significant differences based on gender, practice setting, and level of experience exist in disclosure and documentation of intraoperative GASCs. Additional studies are needed to further explore reasons for these differences, as reporting patterns may affect patient satisfaction, medicolegal risks, and postoperative surgeon-experienced anxiety.

RESUMEN

Background: Venous thromboembolism (VTE) is a preventable, common vascular disease that has been estimated to affect up to 900,000 people per year. It has been associated with risk factors such as recent surgery, cancer, and hospitalization. VTE surveillance for patient management and safety can be improved via natural language processing (NLP). NLP tools have the ability to access electronic medical records, identify patients that meet the VTE case definition, and subsequently enter the relevant information into a database for hospital review. Objective: We aimed to evaluate the performance of a VTE identification model of IDEAL-X (Information and Data Extraction Using Adaptive Learning; Emory University)-an NLP tool-in automatically classifying cases of VTE by "reading" unstructured text from diagnostic imaging records collected from 2012 to 2014. Methods: After accessing imaging records from pilot surveillance systems for VTE from Duke University and the University of Oklahoma Health Sciences Center (OUHSC), we used a VTE identification model of IDEAL-X to classify cases of VTE that had previously been manually classified. Experts reviewed the technicians' comments in each record to determine if a VTE event occurred. The performance measures calculated (with 95% CIs) were accuracy, sensitivity, specificity, and positive and negative predictive values. Chi-square tests of homogeneity were conducted to evaluate differences in performance measures by site, using a significance level of .05. Results: The VTE model of IDEAL-X "read" 1591 records from Duke University and 1487 records from the OUHSC, for a total of 3078 records. The combined performance measures were 93.7% accuracy (95% CI 93.7%-93.8%), 96.3% sensitivity (95% CI 96.2%-96.4%), 92% specificity (95% CI 91.9%-92%), an 89.1% positive predictive value (95% CI 89%-89.2%), and a 97.3% negative predictive value (95% CI 97.3%-97.4%). The sensitivity was higher at Duke University (97.9%, 95% CI 97.8%-98%) than at the OUHSC (93.3%, 95% CI 93.1%-93.4%; P<.001), but the specificity was higher at the OUHSC (95.9%, 95% CI 95.8%-96%) than at Duke University (86.5%, 95% CI 86.4%-86.7%; P<.001). Conclusions: The VTE model of IDEAL-X accurately classified cases of VTE from the pilot surveillance systems of two separate health systems in Durham, North Carolina, and Oklahoma City, Oklahoma. NLP is a promising tool for the design and implementation of an automated, cost-effective national surveillance system for VTE. Conducting public health surveillance at a national scale is important for measuring disease burden and the impact of prevention measures. We recommend additional studies to identify how integrating IDEAL-X in a medical record system could further automate the surveillance process.

RESUMEN

OBJECTIVE: Analyze the impact of the Affordable Care Act (ACA) on trauma outcomes at a population level and within at-risk subgroups. BACKGROUND: Trauma disproportionately affects the uninsured. Compared to the insured, uninsured patients have worse functional outcomes and increased mortality. The goal of the ACA was to increase access to insurance. METHODS: An interrupted time series was conducted using data from the National Inpatient Sample database between 2011 and 2016. Data from Alberta, Canada was used as a control group. Mortality, length of stay, and probability of discharge home with or without home health care was examined using monthly time intervals, with January 2014 as the intervention time. Single and multiple group interrupted time series were conducted. Subgroup analyses were conducted using income quartiles and race. RESULTS: After the intervention, there was a monthly reduction in mortality of 0.0148% ( P < 0.01) in the American cohort: there was no change in the Canadian cohort. The White subgroup experienced a mortality reduction: the non-White subgroup did not. There was no significant change in length of stay or discharge home rate at a population level. There was a monthly increase in the probability of discharge with home health (0.0247%: P < 0.01); this was present in the lower-income quartiles and both race groups. The White subgroup had a higher rate of utilization of home health pre-ACA, and this discrepancy persisted post-ACA. CONCLUSIONS: The ACA is associated with improved mortality and increased use of home health services. Discrepancies amongst racial groups and income quartiles are present.

RESUMEN

PURPOSE: To determine volume fill levels, estimated costs, and force expulsion requirements per bottle of topical ophthalmic steroids commonly used in the United States. SETTING: Tertiary care academic referral center. DESIGN: Prospective laboratory investigation. METHODS: 8 commercially available medications were tested: loteprednol 0.5%, loteprednol gel 0.5%, loteprednol gel 0.38%, difluprednate 0.05%, generic fluorometholone 0.1%, branded fluorometholone 0.1%, generic prednisolone 1.0%, and branded prednisolone 1.0%. 10 bottles of each medication were tested. A double-blinded method was used to measure actual bottle fill volume and number of drops dispensed per bottle. The total perioperative cost per drop was calculated for each medication using a mean cash price. Force requirements were measured using a customized force gauge apparatus. Formulations were compared using Kruskal-Wallis 1way analysis of variances. RESULTS: All formulations were able to cover postoperative periods commensurate with commonly used dosing regimens for cataract surgery. All medications had greater than sticker volume. Loteprednol 0.5% suspension and branded fluorometholone had the highest and lowest number of drops among the medications tested, respectively. Loteprednol 0.38% gel was the most expensive medication, whereas generic prednisolone 1.0% was the least expensive. Gel and branded formulations of ophthalmic steroids required less expulsion force compared with other tested formulations. CONCLUSIONS: Volume fill levels, patient-incurred costs, and expulsion force requirements per bottle of topical steroid medications vary widely. Clinicians may wish to consider these findings when determining their perioperative prescribing regimen.

RESUMEN

PURPOSE: To report refractive and keratometric astigmatism outcomes of resident-performed limbal relaxing incisions (LRIs) during cataract surgery. SETTING: Tertiary care academic teaching hospital. DESIGN: Retrospective case series. METHODS: The length, location, and number of LRIs were determined preoperatively using an online calculator. Variables studied were preoperative keratometry and postoperative uncorrected and corrected distance visual acuity, refraction, and keratometry at 1-month, 3-month, and 12-month visits (POM1, POM3, and POM12, respectively). Subgroup analysis was performed on amount and type of astigmatism. The astigmatism double-angle plot tool and analysis of with-the-wound (WtW) and against-the-wound (AtW) changes were used to assess the effect of astigmatism correction at POM1, POM3, and POM12 visits. RESULTS: In 118 eyes, a higher percentage of eyes demonstrated refractive astigmatism 0.25 diopter (D) or less, 0.50 D or less, 0.75D or less, and 1.0 D or less at POM1 and POM12 (all P < .05) compared with preoperative keratometric astigmatism. Subgroup analysis showed improvement in all groups and types of astigmatism (P < .01). Patients achieved a statistically significant reduction of keratometric astigmatism at POM1, POM3, and POM12 (all P ≤ .0001) relative to baseline, and changes differed significantly based on the preoperative amount of astigmatism (all P ≤ .0001, with greater reductions associated with higher baseline astigmatism) but not by location of the steep meridian. There were significant WtW-AtW changes at POM1, POM3, and POM12. Regression of effect after 1 month was approximately 0.11 D. CONCLUSIONS: Resident-performed LRIs achieved effective and sustained reduction of both refractive and keratometric astigmatism regardless of meridian or magnitude of astigmatism for at least 1 year postoperatively.

RESUMEN

OBJECTIVES: To determine whether previously undetected occult micrometastasis (MM) or isolated tumor cells (ITC) is associated with increased recurrence odds in stage I-II endometrioid adenocarcinoma. METHODS: Women with recurrent stage I/II EC who had complete pelvic and para-aortic were identified as the outcome of interest. A case-control study was designed with the exposure defined as occult MM/ITC not seen on original nodal pathology. Controls were found by frequency-matching in a 1:2 case control ratio. Original nodal slides were re-reviewed, stained and tested with immunohistochemical to detect occult MM/ITC and the odds of associated recurrence was calculated. RESULTS: Of 153 included, 50 with and 103 without recurrence, there was no difference in age (p = 0.46), race (p = 0.24), stage (p = 0.75), FIGO grade (p = 0.64), lymphovascular space invasion (LVSI); p = 1.00, or GOG 99 high-intermediate risk (HIR) criteria (p = 0.35). A total of 18 ITC (11.8%) and 3 MM (2.0%) not previously identified were found in 19 patients. Finding occult MM/ITC was not associated with more lymph nodes (LN) removed (p = 0.67) or tumor grade (p = 0.48) but was significantly associated with stage (p < 0.01). LVSI (p = 0.09) and meeting high-intermediate risk criteria (p = 0.09), were closely associated but not statistically significant. Isolated ITC were not associated with increased odds for recurrence (OR 0.71, CL: 0.20 - 2.22, p = 0.57), recurrence free survival (RFS) (p = 0.85) or overall survival (OS) (p = 0.92). CONCLUSIONS: In early-stage EC, identification of occult MM or ITC is uncommon and associated with stage. The presence of ITC was not associated with increased odds of recurrence. Adjusting stage or treatment may avoided based on ITC alone. Isolated MM were rare in our population, and further investigation is warranted.

RESUMEN

Uninsured and low socioeconomic status patients who suffer burn injuries have disproportionately worse morbidity and mortality. The Affordable Care Act was signed into law with the goal of increasing access to insurance, with Medicaid expansion in January 2014 having the largest impact. To analyze the population-level impact of the Affordable Care Act on burn outcomes, and investigate its impact on identified at-risk subgroups, a retrospective time series of patients was created using data from the Healthcare Cost and Utilization Project National Inpatient Sample database between 2011 and 2016. An interrupted time series analysis was conducted to examine mortality, length of stay, and the probabilities of discharge home, home with home health, and to another facility before and after January 2014. There were no changes in burn mortality detected. There was a statistically significant reduction in the probability of being discharged home (-0.000967, P < .01; 95% confidence interval [CI] -0.0015379 to -0.0003962) or discharged home with home health (-0.000709, P < .01; 95% CI -0.00110 to 0.000317) after 2014. There was an increase in the probability of being discharged to another facility (0.00108, P = .01; 95% CI 0.000282-0.00188). While the enactment of the major provisions of the Affordable Care Act in 2014 was not associated with a change in mortality for burn patients, it was associated with more patients being discharged to a facility: This may represent a significant improvement in access to care and rehabilitation. Future studies will assess the societal and economic impact of improved access to post-discharge facilities and rehabilitation.
