While previous epidemiologic research has demonstrated that sexual assault survivors (SAS) may be at disproportionate risk for exposure to Hepatitis C (HCV), HCV screening in SAS is not addressed in current post-sexual assault testing recommendations. We sought to identify the prevalence of HCV among a SAS cohort along with associated basic demographics. Opt-out HCV antibody screening and RNA confirmatory testing was provided for all SAS at a Sexual Assault Nurse Examiner (SANE) clinic in Birmingham, Alabama, from April 2020 through March 2021. A retrospective chart review was conducted using descriptive statistical and Chi-squared analyses. A total of 293 SAS presented to the clinic during the study timeframe. Two hundred forty-two (82.6%) were screened for HCV and 26 (8.9%) were found to be HCV antibody (Ab) positive [significantly higher than state (1.0%) and national (1.0%) HCV incidence rates (p 0.0001)]. SAS age groups 25-34 and 35-44 were more likely to screen HCV Ab-positive (15.2% and 14.9% respectively; p = 0.02). Female SAS were more likely to be tested for HCV then males (p = 0.02), although male SAS were more likely to be found HCV Ab-positive when screened (24.4%, p 0.0001). Overall, SAS demographics also demonstrate the presence of significant social vulnerabilities, specifically high rates of homelessness (4.4%) and incarceration (5.1%). This data highlight the potential impact of universal HCV screening and risk counselling in a high social risk population and suggests a potential for future focused interventions.

The promising developments in gene and cell therapy bring an array of hope to the7000 rare disease patient communities, of which 90% to 95% are still working toward a treatment. However, the pace of gene and cell therapy development pathways often resembles ultramarathon relay races that potentially span decades. It is a pace that is incongruent to the sprint that most individuals with rare diseases and their families are living and working in pursuit of life-saving treatments. It is also challenging for the medical professionals, academic researchers, and pharmaceutical partners working tirelessly to bring a treatment to reality. Gene and cell therapy development programs can have many parallels to an ultramarathon, including extensive training and preparation leading up to clinical trials, selecting inclusion and exclusion criteria, supporting trial participants, and creating support teams. All aspects of the development course carry the greatest hope that as many treatments as possible can cross the finish line. Drawing on this analogy, perspectives and insights from a patient family member and rare disease advocacy leader in a community that has experienced its first clinical trial of gene therapy is shared. Bringing attention to these experiences, challenges, barriers, and potential learnings from a patient family perspective will likely encourage continued improvements in development of patient-driven gene and cell drug and therapy for the rare disease community.

Introduction: Research has shown higher rates of suicidal ideation among people who identify as sexual minorities (e.g., homosexual, bisexual, asexual, pansexual, other). This increased risk may stem from the relationship between internalized stigma and negative mental health outcomes in sexual minorities. However, there is a gap in research surrounding the effects of stigma on internal mechanisms, such as psychological pain, in sexual minorities. This study examined the relationship between internalized stigma of sexual orientation, psychological pain, and suicidal thoughts and behaviors. Methods: The data was from a larger study conducted at a northeastern university (mean age = 19, SD = 1.86). Participants completed measures related to internalized stigma of sexual orientation, psychological pain, and suicidal thoughts and behaviors. Results: There was a significant group difference in internalized stigma of sexual orientation, with sexual minorities having higher scores. It was found that internalized stigma of sexual orientation moderated the relationship between psychological pain and suicidal thoughts and behaviors, where higher levels of internalized stigma of sexual orientation was related to higher levels of psychological pain and suicidal thoughts and behaviors. Discussion: The results highlight the importance of understanding internalized stigma and its relationships with psychological pain and suicidal thoughts and behaviors.

Childhood sexual abuse (CSA) increases risk for posttraumatic stress disorder (PTSD), and both CSA and PTSD are strongly associated with impaired social functioning. Interpersonal psychotherapy (IPT) has demonstrated promise for adults with PTSD and has been shown to be effective for women with PTSD and histories of CSA, but the mechanisms by which IPT might improve PTSD are unknown. The current secondary analysis tested whether the ameliorative effect of IPT-trauma (IPT-T) on PTSD, demonstrated in a randomized effectiveness trial, was mediated by improved social function.The randomized effectiveness trial compared IPT-T to clinic psychotherapy in a publicly funded community mental health center. Women with CSA histories and major depression (Mediation models confirmed hypotheses, showing that the effect of IPT-T on improved PTSD symptoms at Week 32 (end of treatment) was partially mediated by better social functioning at Week 16 (middle of treatment period; pathFindings support that a non-exposure-based therapy can reduce PTSD symptoms via improved social functioning. Given extensive literature showing the importance of social functioning in mental health generally and PTSD specifically, integrating a focus on social functioning (e.g., building social skills, expanding support networks) into treatments, including exposure-based treatments, may enhance outcomes.

OBJECTIVE: To investigate perspectives of patients, family members, caregivers (PFC), and healthcare professionals (HCP) on tracheostomy care during the COVID-19 pandemic. METHODS: The cross-sectional survey investigating barriers and facilitators to tracheostomy care was collaboratively developed by patients, family members, nurses, speech-language pathologists, respiratory care practitioners, physicians, and surgeons. The survey was distributed to the Global Tracheostomy Collaborative's learning community, and responses were analyzed. RESULTS: Survey respondents (n = 191) from 17 countries included individuals with a tracheostomy (85 [45 %]), families/caregivers (43 [22 %]), and diverse HCP (63 [33.0 %]). Overall, 94 % of respondents reported concern that patients with tracheostomy were at increased risk of critical illness from SARS-CoV-2 infection and COVID-19; 93 % reported fear or anxiety. With respect to prioritization of care, 38 % of PFC versus 16 % of HCP reported concern that patients with tracheostomies might not be valued or prioritized (p = 0.002). Respondents also differed in fear of contracting COVID-19 (69 % PFC vs. 49 % HCP group, p = 0.009); concern for hospitalization (55.5 % PFC vs. 27 % HCP, p

Undifferentiated carcinoma with osteoclast-like giant cells (UC-OGC) is an exceedingly rare subtype of pancreatic ductal adenocarcinoma. Histologically, UC-OGC is characterized by three cell types namely, a neoplastic mononuclear cell component, non-neoplastic osteoclast-like giant cells, and a non-neoplastic mononuclear histiocytic component. The behavior of this tumor is unpredictable; but many patients survive many years after diagnosis. UC-OGC may have a better prognosis compared to conventional pancreatic adenocarcinoma due to its slower local spread, less aggressive nature, better response to surgical resection and/or chemotherapy, and fewer metastases. Due to likely differences in prognosis and significant impact on patient management, it is important to distinguish this subtype from other types of pancreatic adenocarcinoma. We report a case of a small (1 cm) undifferentiated carcinoma with osteoclast-like giant cells of the posterior pancreatic body discovered incidentally on magnetic resonance image (MRI) scan of a middle-aged man. The radiologic and pathologic findings are presented along with a discussion of the differential diagnosis of this exceedingly rare entity.

OBJECTIVE: Investigate healthcare providers, caregivers, and patient perspectives on tracheostomy care barriers during COVID-19. STUDY DESIGN: Cross-sectional anonymous survey SETTING: Global Tracheostomy Collaborative Learning Community METHODS: A 17-item questionnaire was electronically distributed, assessing demographic and occupational data; challenges in ten domains of tracheostomy care; and perceptions regarding knowledge and preparedness for navigating the COVID-19 pandemic. RESULTS: Respondents (n = 115) were from 20 countries, consisting of patients/caregivers (10.4%) and healthcare professionals (87.0%), including primarily otolaryngologists (20.9%), nurses (24.3%), speech-language pathologists (18.3%), respiratory therapists (11.3%), and other physicians (12.2%). The most common tracheostomy care problem was inability to communicate (33.9%), followed by mucus plugging and wound care. Need for information on how to manage cuffs and initiate speech trials was rated highly by most respondents, along with other technical and knowledge areas. Access to care and disposable supplies were also prominent concerns, reflecting competition between community needs for routine tracheostomy supplies and shortages in intensive care units. Integrated teamwork was reported in 40 to 67% of respondents, depending on geography. Forty percent of respondents reported concern regarding personal protective equipment (PPE), and 70% emphasized proper PPE use. CONCLUSION: While safety concerns, centering on personal protective equipment and pandemic resources are prominent concerns in COVID-19 tracheostomy care, patient-centered concerns must also be prioritized. Communication and speech, adequate supplies, and care standards are critical considerations in tracheostomy. Stakeholders in tracheostomy care can partner to identify creative solutions for delays in restoring communication, supply disruptions, and reduced access to tracheostomy care in both inpatient and community settings.

BACKGROUND Cognitive behavioral therapy (CBT)-based interventions are effective in reducing prenatal stress, which can have severe adverse health effects on mother and newborn if unaddressed. Predicting next-day physiologic or perceived stress can help to inform and enable preemptive interventions for a likely physiologically and/or perceptibly stressful day. Machine learning models are useful tools that can be developed to predict next-day physiologic and perceived stress using data collected the previous day. Such models can improve our understanding of the specific factors that predict physiologic and perceived stress and will also allow researchers to develop systems that collect selected features for assessment for clinical trials in order to minimize the burden of data collection. OBJECTIVE To build and evaluate a machine-learned model that predicts next-day physiologic and perceived stress using sensor-based, ecological momentary assessment (EMA)-based, and intervention-based features and to explain the prediction results. METHODS We enrolled pregnant women into a prospective proof-of-concept study and collected electrocardiography, EMA, and CBT intervention data over 12 weeks. We used the data to train and evaluate six machine learning models to predict next-day physiologic and perceived stress. After selecting the best performing model, SHapley Additive exPlanations (SHAP) were used to identify feature importance and explainability of each feature. RESULTS A total of 16 pregnant women enrolled in the study. Overall, 4157.18 hours of data were collected, and participants answered 2838 EMAs. After applying feature selection, 8 and 10 features were found to positively predict next-day physiologic and perceived stress, respectively. A random forest classifier performed the best in predicting next-day physiologic (F1-score 0.84) and next-day perceived stress (F1-score 0.74) using all features. While any subset of sensor-based, EMA-based, and/or intervention-based features could reliably predict next-day physiologic stress, EMA-based features were necessary to predict next-day perceived stress. Analysis of explainability metrics showed that prolonged duration of physiologic stress was highly predictive of next-day physiologic stress and that physiologic stress and perceived stress were temporally divergent. CONCLUSIONS In this study we were able to build interpretable machine learning models to predict next-day physiologic and perceived stress, and we identify unique features that were highly predictive of next-day stress that can help reduce the burden of data collection.

The aim of this study is to assess the impact of preoperative comanagement with complex care pediatricians (CCP) on children with neuromuscular scoliosis undergoing spinal fusion. We performed chart review of 79 children aged 5–21 years undergoing spinal fusion 1/2014–6/2016 at a children’s hospital, with abstraction of clinical documentation from preoperative health evaluations performed regularly by anesthesiologists and irregularly by a CCP. Preoperative referrals to specialists, labs, tests, and care plans needed last minute for surgical clearance were measured. The mean age at surgery was 14 (SD 3) years; cerebral palsy (64%) was the most common neuromuscular condition. Thirty-nine children (49%) had a preoperative CCP evaluation a median 63 days (interquartile range (IQR) 33–156) before the preanesthesia visit. Children with CCP evaluation had more organ systems affected by coexisting conditions than children without an evaluation (median 11 (IQR 9–12) vs. 8 (IQR 5–11); p < .001). The rate of last-minute care coordination activities required for surgical clearance was lower for children with versus without CCP evaluation (1.8 vs. 3.6). A lower percentage of children with CCP evaluation required last-minute development of new preoperative plans (26% vs. 50%, p = .002). Children with CCP involvement were better prepared for surgery, requiring fewer last-minute care coordination activities for surgical clearance.

An incidental appendectomy is performed by some surgeons during operative treatment for intussusception to eliminate future appendicitis as a diagnostic consideration. However, an appendectomy can increase the risk of infection and other noninfectious complications making an incidental appendectomy controversial. We examined outcomes for surgical intervention for intussusception with appendectomy (SWA) compared to surgical reduction alone (SRA).The Pediatric Health Information System database, 8/2008-9/2015, was retrospectively analyzed for patients under the age of five who required an operative intervention for intussusception without bowel resection. Demographic data and postoperative outcomes were analyzed. Available data included need for postoperative enema, subsequent small bowel obstruction, recurrent intussusception, length of stay (LOS), and adjusted total cost (ATC).Fifty-seven percent (748/1312) of patients had appendectomy performed during surgical reduction, 564 (43%) did not. ATC ($10,594 vs. $8939, p 0.001) and LOS (3.0 vs. 2.48, p 0.001) are higher in the SWA group. Rates of readmission are similar, but post-operative small bowel obstruction may be higher in the SWA group (1.3% vs. 0.35%, p = 0.06).There is a higher mean LOS and ATC in the SWA group. This study suggests that appendectomy during surgery for uncomplicated intussusception should be reconsidered and requires further investigation.retrospective comparative study.III.

Family perspectives on short-term recovery after spinal fusion for neuromuscular scoliosis are essential for improving patient outcomes. Semistructured interviews were conducted with 18 families of children within 3 months after spinal fusion performed August 2017 to January 2019 at a children’s hospital. Interviews were recorded, transcribed, and coded line-by-line by 2 independent reviewers using grounded theory to identify themes. Five themes emerged among families when reflecting back on the postoperative recovery: (1) communicating and making shared decisions regarding postoperative care in a patient- and family-centered manner, (2) setting hospital discharge goals and being ready for discharge, (3) planning for transportation from hospital to home, (4) acquiring supports for caregiving at home after discharge, and (5) anticipating a long recovery at home. Important family perceptions were elicited about the recovery of children from spinal fusion for neuromuscular scoliosis that will inform better perioperative planning for clinicians, future patients, and their families.

Global health care is experiencing an unprecedented surge in the number of critically ill patients who require mechanical ventilation due to the COVID-19 pandemic. The requirement for relatively long periods of ventilation in those who survive means that many are considered for tracheostomy to free patients from ventilatory support and maximise scarce resources. COVID-19 provides unique challenges for tracheostomy care: health-care workers need to safely undertake tracheostomy procedures and manage patients afterwards, minimising risks of nosocomial transmission and compromises in the quality of care. Conflicting recommendations exist about case selection, the timing and performance of tracheostomy, and the subsequent management of patients. In response, we convened an international working group of individuals with relevant expertise in tracheostomy. We did a literature and internet search for reports of research pertaining to tracheostomy during the COVID-19 pandemic, supplemented by sources comprising statements and guidance on tracheostomy care. By synthesising early experiences from countries that have managed a surge in patient numbers, emerging virological data, and international, multidisciplinary expert opinion, we aim to provide consensus guidelines and recommendations on the conduct and management of tracheostomy during the COVID-19 pandemic.

BackgroundWork describing patient and family outcomes after tracheostomy has indicated that patients do not feel prepared at the time of discharge.ObjectivesTo assess healthcare professional–patient interactions in tracheostomy care and the current provision of care.MethodA global electronic survey was disseminated via e-mail.ResultsThe majority of respondents were nursing or speech and language staff, from over 10 countries. Only 23 per cent of respondents’ institutions routinely offered patients the ability to meet people with a tracheostomy pre-operatively. Only 31 per cent consistently provided or co-ordinated full nursing and equipment requirements on discharge. Only half of the institutions participated in tracheostomy quality improvement initiatives; less than one-third of these involved patients.ConclusionThe provision of tracheostomy care in hospital and at discharge can be improved. The current practice of clinician-led audit is becoming less viable; future initiatives should focus upon patient-centred outcomes to ensure excellence in healthcare delivery.

Serum D-dimer has been proposed as a biomarker to aid in the diagnosis of pediatric traumatic brain injury (TBI). We investigated the accuracy of D-dimer in predicting the absence of TBI and evaluated the degree by which D-dimer could limit unnecessary computed tomography scans of the head (CTH).Retrospective review of patients with suspected TBI from 2011 to 2013 who underwent evaluation with CTH and quantitative D-dimer. D-dimer levels were compared among patients with clinically-important TBI (ciTBI), TBI, isolated skull fracture and no injury.Of the 663 patients evaluated for suspected TBI, ciTBI was identified in 116 (17.5%), TBI in 77 (11.6%), skull fracture in 61 (9.2%) and no head injury in 409 (61.7%). Patients with no head injury had significantly lower D-dimer values (1531±1791pg/μL) compared to those with skull fracture, TBI and ciTBI (2504±1769, 2870±1633 and 4059±1287pg/μL, respectively, p0.005). Using a D-dimer value750pg/μL as a negative screen, no ciTBIs would be missed and 209 CTHs avoided (39.7% of total).Low plasma D-dimer predicts the absence of ciTBI for pediatric patient with suspected TBI. Incorporating D-dimer into current diagnostic algorithms may significantly limit the number of unnecessary CTHs performed in this population.Study of diagnostic test.I.

Background Retained foreign bodies (RFOs) have substantial clinical and financial consequences. In laparoscopic surgery, RFOs can be a cause of needing to convert a minimally invasive surgery (MIS) procedure to an open operation. A coating for surgical models was developed to augment localization of needles using fluorescence appropriate for open and minimally invasive surgeries procedures. Methods An epoxy matrix containing both dansyl chloride and indocyanine green was coated as visible and near infrared labels, respectively. With ultraviolet excitation, dansyl chloride emits green fluorescence and with NIR excitation, the ICG dye emits radiation observable with specialized near infrared capable laparoscopes. To evaluate the coatings, open and laproscopic surgeries were simulated in rabbits. Surgeons blinded to the type of needles (coated or non-coated) were timed while finding needles in standard conditions and with the use of the adjunct coatings. Control needles not located within 300 seconds were researched with the corresponding near infrared or ultraviolet light. Localization time was evaluated for statistical significance, P Results All dual dye coated needles searched utilizing the near infrared camera (n = 26) or ultraviolet light (n = 26) were located within 300 seconds. Conversely, 9 needles in both control settings (no dye usage) were not located within 300 seconds. Mean time to locate control needles in open surgery and laparoscopic surgery was statistically 2-3× greater than time to localization with the use of dye as an adjunct (P = .0027 open, P Conclusion Incorporation of a dual-dye fluorescent coating on surgical needles improved the efficiency of locating needles, may minimize the need to convert minimally invasive surgeries procedures to open, and may decrease the consequences of a missed RFO.

Uncontrolled noise in the hospital setting can have a negative physiological and psychological impact on patients and nurses. To reduce unit noise levels and create a quiet patient and nurse experience, an evidence-based practice project was conducted in 4 progressive care units in a community hospital. The Quiet Time Bundle implementation improved patient satisfaction and patient and nurse perceptions of noise even though the decrease in noise levels may not be discernible.

Patients with congenital diaphragmatic hernia (CDH), gastroschisis, and omphalocele are prone to abnormalities of intestinal rotation and thus future midgut volvulus. Controversy exists whether routine preemptive Ladd procedure in this subgroup of asymptomatic patients is of value to reduce future volvulus.The Pediatric Health Information System (PHIS) database was queried for neonates with CDH, gastroschisis, and omphalocele between January 2009 and September 2015. Standard univariate and multivariate analysis was completed to compare risk of volvulus between patients treated with a preemptive Ladd versus no Ladd (p0.05).Seven thousand seven hundred forty-nine neonates with CDH (40%), gastroschisis (38%), omphalocele (14%), and abdominal wall malformation (NOS) (9%) were identified. Overall, 3.6% (n=279) had a preemptive. Thirty-two patients had subsequent volvulus. Ladd procedure did not reduce volvulus readmissions for any diagnosis and was associated with a significantly increased risk of volvulus for omphalocele patients (9.1% vs 0.1%, p0.001). Overall, a Ladd procedure during the index admission was associated with a higher risk for volvulus (1.4% vs. 0.4%, p=0.021) and was associated with a 3.28 increased odds ratio of future volvulus (95% CI 1.12-9.68).Ladd procedure performed prophylactically in patients with CDH, gastroschisis, and omphalocele did not reduce subsequent volvulus.III, Retrospective Comparative Study.

Ultrasound (US) guided medical devices placement is a widely used clinical technology, yet many factors affect the visualization of these devices in the human body. In this research, an ultrasound-activated film was developed that can be coated on the surface of medical devices. The film contains 2 μm silica microshells and poly(methyl 2-cyanoacrylate) (PMCA) adhesive. The air sealed in the hollow space of the microshells acted as the US contrast agent. Ozone and perfluorooctyltriethoxysilane (PFO) were used to treat the surface of the film to enhance the US signals and provide durable antifouling properties for multiple passes through tissue, consistent with the dual oleophobic and hydrophobic nature of PFO. In vitro and in vivo tests showed that hypodermic needles and tumor marking wires coated with US activated film gave strong and persistent color Doppler signals. This technology can significantly improve the visibility of medical devices and the accuracy of US guided medical device placement.

Introduction: Online breast cancer communities provide users with both information and emotional support. Members of these communities include both patients and caregivers. We aimed to characterize the differences in content between patients' and caregivers' first posts. Methods: 20189 posts were downloaded from a public online breast cancer community. Posts were sorted by user name and date to identify unique posters and coded for user demographics and content. Descriptive statistics (e.g. chi-square test) characterized differences between patients and caregivers in terms of topics and content. Results: Of the 1827 unique posters, 83% were identified as the patient (n=1277, 70%) and 13% were identified as a caregiver (n=230). 835 (69%) patients had been previously diagnosed with breast cancer. Chemotherapy was the most common topic among cancer patients. Patients tended to seek information about physical concerns more often than psychosocial concerns. In contrast, caregivers used the community significantly more often as a source of emotional support (p Breast Cancer Patients' Topics of ConversationTopicN(%)ExplanationExampleChemotherapy296 (36)Patients discussing the decision for chemotherapy, or their experiences with it.“I was allergic to some of the chemo meds”Radiation255 (31)Patients discussing the decision for radiation, or their experiences with it.“I wanted to answer your query about radiation…”Estrogen Modulating Therapy156 (19)Patients discussing the decision to take estrogen modulating medications (e.g. Tamoxifen) or their experiences with it.“I don't know if I'm going to take this with all the side effects I read.”Surgery55 (7)Patients discussing surgical options for breast cancer treatment (not reconstruction) or experiences with the procedures.“I don't want them to leave half of my breast with a chance for a new diagnosis”Reconstruction49 (6)Patients discussing reconstruction options or experiences with the procedures.“I recently had a TE recon and it went fine but a week later i developed an infection…” Thematic Content of Posts: Patients v.

Patients' first posts were often information-seeking about physical concerns, whereas caregivers tended to use the forum as a source of emotional support. By analyzing the frequency of topics and content of posts, clinicians may better understand the educational needs of patients and caregivers.

Ultrasound imaging is a safe, low-cost, and in situ method for detecting in vivo medical devices. A poly(methyl-2-cyanoacrylate) film containing 2 μm boron-doped, calcined, porous silica microshells was developed as an ultrasound imaging marker for multiple medical devices. A macrophase separation drove the gas-filled porous silica microshells to the top surface of the polymer film by controlled curing of the cyanoacrylate glue and the amount of microshell loading. A thin film of polymer blocked the wall pores of the microshells to seal air in their hollow core, which served as an ultrasound contrast agent. The ultrasound activity disappeared when curing conditions were modified to prevent the macrophase segregation. Phase segregated films were attached to multiple surgical tools and needles and gave strong color Doppler signals in vitro and in vivo with the use of a clinical ultrasound imaging instrument. Postprocessing of the simultaneous color Doppler and B-mode images can be used for autonomous identification of implanted surgical items by correlating the two images. The thin films were also hydrophobic, thereby extending the lifetime of ultrasound signals to hours of imaging in tissues by preventing liquid penetration. This technology can be used as a coating to guide the placement of implantable medical devices or used to image and help remove retained surgical items.

Background Currently, the gold standard diagnostic examination for significant aortoiliac lesions is angiography. Fractional flow reserve (FFR) has a growing body of literature in coronary artery disease as a minimally invasive diagnostic procedure. Improvements in numerical hemodynamics have allowed for an accurate and minimally invasive approach to estimating FFR, utilizing cross-sectional imaging. We aim to demonstrate a similar approach to aortoiliac occlusive disease (AIOD). Methods A retrospective review evaluated 7 patients with claudication and cross-sectional imaging showing AIOD. FFR was subsequently measured during conventional angiogram with pull-back pressures in a retrograde fashion. To estimate computed tomography (CT) FFR, CT angiography (CTA) image data were analyzed using the SimVascular software suite to create a computational fluid dynamics model of the aortoiliac system. Inlet flow conditions were derived based on cardiac output, while 3-element Windkessel outlet boundary conditions were optimized to match the expected systolic and diastolic pressures, with outlet resistance distributed based on Murray's law. The data were evaluated with a Student's t-test and receiver operating characteristic curve. Results All patients had evidence of AIOD on CT and FFR was successfully measured during angiography. The modeled data were found to have high sensitivity and specificity between the measured and CT FFR (P = 0.986, area under the curve = 1). The average difference between the measured and calculated FFRs was 0.136, with a range from 0.03 to 0.30. Conclusions CT FFR successfully identified aortoiliac lesions with significant pressure drops that were identified with angiographically measured FFR. CT FFR has the potential to provide a minimally invasive approach to identify flow-limiting stenosis for AIOD.

Summary There is growing recognition of the need for a coordinated, systematic approach to caring for patients with a tracheostomy. Tracheostomy-related adverse events remain a pervasive global problem, accounting for half of all airway-related deaths and hypoxic brain damage in critical care units. The Global Tracheostomy Collaborative (GTC) was formed in 2012 to improve patient safety and quality of care, emphasising knowledge, skills, teamwork, and patient-centred approaches. Inspired by quality improvement leads in Australia, the UK, and the USA, the GTC implements and disseminates best practices across hospitals and healthcare trusts. Its database collects patient-level information on quality, safety, and organisational efficiencies. The GTC provides an organising structure for quality improvement efforts, promoting safety of paediatric and adult patients. Successful implementation requires instituting key drivers for change that include effective training for health professionals; multidisciplinary team collaboration; engagement and involvement of patients, their families, and carers; and data collection that allows tracking of outcomes. We report the history of the collaborative, its database infrastructure and analytics, and patient outcomes from more than 6500 patients globally. We characterise this patient population for the first time at such scale, reporting predictors of adverse events, mortality, and length of stay indexed to patient characteristics, co-morbidities, risk factors, and context. In one example, the database allowed identification of a previously unrecognised association between bleeding and mortality, reflecting ability to uncover latent risks and promote safety. The GTC provides the foundation for future risk-adjusted benchmarking and a learning community that drives ongoing quality improvement efforts worldwide.

Although the results of clinical trials often guide best practices, changing clinical practice based on clinical trial results can be challenging. The objective of this study was to examine provider-reported barriers to adopting best clinical practices according to clinical trial data. A cross-sectional survey was conducted of providers from the National Accreditation Program for Breast Centers about barriers that prevent the incorporation of trial findings. Descriptive analyses and multivariable analyses were performed to determine provider characteristics that were significantly associated with reported barriers. Overall, 383 institutions participated (63.5% response rate), with a total of 1226 physicians responding to the survey (80% response rate). Providers identified national guidelines and meetings as the most compelling way to receive practice-changing information. They reported the following internal barriers to trial implementation: patient preference (45%), strongly held beliefs by partners/colleagues (37%), and insufficient time to discuss new practices (30%). External barriers preventing trial implementation included a lack of agreement from multidisciplinary tumor boards (32%), fear of reimbursement loss (23%), and resistance from clinical staff (20%). Reported barriers differed by provider specialty, with plastic surgeons and radiation oncologists reporting that strongly held beliefs by partners/colleagues and disagreement from multidisciplinary tumor boards were the most significant factors preventing clinical trial implementation. Physician beliefs and patient preferences are the most frequently reported barriers to clinical trial implementation. Tactics to better educate providers about how to explain new clinical trial data to their patients and colleagues are needed.

Objectives To convey advice from families whose children recently underwent spinal fusion to families whose children are under consideration for initial spinal fusion for neuromuscular scoliosis and to providers who counsel families on this decision. Study design We interviewed 18 families of children who underwent spinal fusion between August 2017 and January 2019 at a freestanding children's hospital. We conducted phone interviews a median of 65 (IQR 51-77) days after surgery. We audio recorded, transcribed, and coded (line-by-line) interviews using grounded theory by 2 independent reviewers, and discussed among investigators to induce themes associated with surgical decision making and preparation. Results Six themes emerged about decision making and preparation for spinal fusion: (1) simplify risks and benefits; it is easy to get lost in the details; (2) families prolonging the decision whether or not to pursue spinal fusion surgery may not benefit the child; (3) anticipate anxiety and fear when making a decision about spinal fusion; (4) realize that your child might experience a large amount of pain; (5) anticipate a long recovery and healing process after spinal fusion; and (6) be engaged and advocate for your child throughout the perioperative spinal fusion process. Conclusions Parents of children who had recently undergone spinal fusion had strong perceptions about what information to convey to families considering surgery, which may improve communication between future parents and physicians. Further investigation is needed to assess how best to incorporate the wisdom and experiences of parent peers into shared decision making and preparation for spinal fusion in children with neuromuscular scoliosis.

The purpose of this study was to understand nurses' perceptions of a newly adopted electronic health record (EHR).As use of EHRs in hospital settings increases, leaders prepare staff members for change. There is limited information about impacts of EHR adoption on RNs using EHRs at the point of care.Clinical RNs were surveyed about 3 domains (ease of use, usefulness, and attitude) before and after implementation of an EHR. A small subset of nurses was interviewed for a deeper understanding of perceptions associated with this change.One year after adoption, nurses believed that the EHR did not improve patient care, the learning curve was steep, and they had lower confidence using the EHR than anticipated. Nurses commented on both their frustration and optimism about EHRs.This study provides insight into RNs' perceptions of an EHR, providing important information for nursing administrators.

Marking colon tumors for surgery is normally done with the use of India ink. However, non-fluorescent dyes such as India ink cannot be imaged below the tissue surface and there is evidence for physiological complications such as abscess, intestinal perforation and inconsistency of dye injection. A novel infrared marker was developed using FDA approved indocyanine green (ICG) dye and ultrathin hollow silica nanoshells (ICG/HSS). Using a positively charged amine linker, ICG was non-covalently adsorbed onto the nanoparticle surface. For ultra-thin wall 100 nm diameter silica shells, a bimodal ICG layer of < 3 nm is was formed. Conversely, for thicker walls on 2 μm diameter silica shells, the ICG layer was only bound to the outer surface and was 6 nm thick. In vitro testing of fluorescent emission showed the particles with the thinner coating were considerably more efficient, which is consistent with self-quenching reducing emission shown in the thicker ICG coatings. Ex-vivo testing showed that ICG bound to the 100 nm hollow silica shells was visible even under 1.5 cm of tissue. In vivo experiments showed that there was no diffusion of the ICG/nanoparticle marker in tissue and it remained imageable for as long as 12 days.

BackgroundPreoperative breast and lung markers have significant drawbacks, including migration, patient discomfort, and scheduling difficulties. SignalMark is a novel localizer device with a unique signal on Doppler ultrasound.ObjectiveWe aimed to evaluate intraoperative identification of SignalMark microspheres compared with HydroMARK® clips. We also assessed the safety and efficacy of SignalMark in the lung.MethodsTwelve breasts of lactating pigs were injected with SignalMark or HydroMARK® by a breast radiologist, and subsequently identified using a standard ultrasound machine by three surgeons blinded to marker location. Time to identification of each marker was recorded, with a maximum allotted time of 300s. To further demonstrate efficacy in lung parenchyma, a second cohort of pigs underwent lung injections.ResultsA total of eight SignalMark markers and four HydroMARK® clips were placed in pig breasts. Overall, the surgeons correctly identified SignalMark 95.8% of the time (n = 23/24) and HydroMARK® clips 41.7% of the time (n = 5/12) within 300 s (p

Background Patient selection for cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is critically important to optimizing outcomes. There is currently no literature regarding the safety of CRS/HIPEC in patients with cirrhosis. The aim of this case series is to report the outcomes of three patients with well-compensated cirrhosis who underwent CRS/HIPEC. Methods Patients were identified from a prospectively maintained peritoneal surface malignancy database. Patient, tumor, and operative-related details were recorded as short-term postoperative outcomes. Results were analyzed using descriptive statistics. Results All patients had well-compensated (Child-Pugh Class A) cirrhosis and Eastern Cooperative Oncology Group (ECOG) performance status of 0. One patient had preoperative evidence of portal hypertension. All safely underwent CRS/HIPEC with completeness of cytoreduction (CC) scores of 0. The postoperative morbidity profile was unique, but all complications were manageable and resulted in full recovery to preoperative baseline status. Conclusions Patient selection for CRS/HIPEC is critical for optimization of short- and long-term outcomes. This small series suggests that well-compensated cirrhosis should not be an absolute contraindication to CRS/HIPEC.

To report patient/family experiences and outcomes after tracheostomyInternational survey of patients and families with tracheostomy.Collaboration of the Patient Safety and Quality Improvement Committee of the American Academy of Otolaryngology-Head and Neck Surgery and the Global Tracheostomy Collaborative.A 50-item survey was developed with multistakeholder collaboration. The survey was disseminated via international social networks used by patients with a tracheostomy and their families. Qualitative and quantitative data were analyzed.Of 220 respondents, 90% cared for a pediatric patient with a tracheostomy. Only 48% of respondents felt "very prepared" at time of discharge, and 11% did not receive emergency preparedness training prior to discharge. Home nursing needs were inadequately met in 17% of families, with resulting difficulties shortly after discharge; 14% sought emergent care within 1 week of discharge. Nearly half of respondents indicated a desire to have met with a patient with a tracheostomy prior to surgery but were not offered that opportunity. Fragmented care or limited teamwork was reported by 32% of respondents, whereas tracheotomy care was described as "integrated" or "maximally integrated" for 67%.While many families report satisfaction with tracheostomy care, opportunities remain for improving care. This study highlights the importance of teaching, teamwork, and smoothing transition from the hospital. Potential quality improvement areas include standardizing tracheostomy teaching for routine and emergency needs and optimizing postdischarge support and coordination. Prior to surgery, connecting families to people with a tracheostomy may also be beneficial.

The purpose of this study is to better characterize the current incidence and treatment patterns of DCIS in women greater than 80 years of age (80) and to evaluate the effect of grade on treatment efficacy.Retrospective observational study of women diagnosed with single primary DCIS from 2000 to 2012 in SEER. Statistics including incidence, multivariable Cox proportional hazards model and subset analysis were performed.42,899 female patients with DCIS were identified, 2566 (5.98%) were80. Incidence of DCIS in the less than 80 (80) cohort was 8 per 100,000 and 11.7 per 100,000 for80.80 patients have a similar incidence of high grade DCIS (9.8%) as compared to80 cohort (10.7%, P = 0.246). Compared to the80 population the80 population received significantly less surgery (97 vs. 92%, P 0.001) and radiation (22 vs. 47%, P 0.001). Although on multivariate analysis surgery did not provide a survival benefit for80 population, it conveyed a survival benefit for high grade DCIS (HR 0.14, 95% CI 02-0.68) that was not observed for low grade DCIS (HR 0.46, 95% CI 0.1-2.03).Patients over 80 years of age have a relatively high incidence of DCIS and receive low relative rates of treatment. Although surgery does not provide a survival benefit for all patients over 80, it does provide a significant survival benefit for patients with high grade DCIS. Our results suggest that perhaps the biology of the DCIS, not the age of the patient should direct who warrants treatment.

We evaluated the impact of travel distance and insurance status on contralateral prophylactic mastectomy (CPM) rates in breast cancer.We queried the National Cancer Data Base (NCDB) for women18 years of age with a nonmetastatic primary breast cancer of ductal, lobular, or mixed histology. Patient- and facility-specific CPM rates were calculated based on insurance, race, and distance to treatment center. Standard univariable and multivariable regression analysis was performed.Overall, the CPM rate was 6.5% for the 864,105 patients identified. Most patients traveled20 miles to a treatment center (79.5%) and had private insurance or Medicare (58.3 and 33.4%, respectively). In general, younger, White, non-Hispanic, and privately insured patients residing further from a treatment center was associated with increased rates of CPM. However, distance to the treatment center and insurance type had a greater absolute impact on rates of CPM for Black and Hispanic patients. Absolute CPM rate increases for patients100 miles from a treatment center compared with those20 miles from a treatment center were observed to be greater for Black and Hispanic patients (3.5 and 3.9%, respectively) compared with White and non-Hispanic patients (2.5 and 2.6%). Additionally, further patient travel distance was associated with higher treatment center-specific CPM rates.Increased travel distance is independently associated with increased rates of CPM for all patients and increased facility-specific rates of CPM. Black and Hispanic patients were found to be more vulnerable to the impact of travel distance and insurance status on rates of CPM.

Background Our aim was to evaluate the ease and utility of using indocyanine green fluorescence angiography for intraoperative localization of the parathyroid glands. Methods Indocyanine green fluorescence angiography was performed during 60 parathyroidectomies for primary hyperparathyroidism during a 22-month period. Indocyanine green was administered intravenously to guide operative navigation using a commercially available fluorescence imaging system. Video files were graded by 3 independent surgeons for strength of enhancement using an adapted numeric scoring system. Results There were 46 (77%) female patients and 14 (23%) male patients whose ages ranged from 17 to 87 (average 60) years old. Of the 60 patients, 43 (71.6%) showed strong enhancement, 13 (21.7%) demonstrated mild to moderate vascular enhancement, and 4 (6.7%) exhibited little or no vascular enhancement. Of the 54 patients who had a preoperative sestamibi scan, a parathyroid adenoma was identified in 36, while 18 failed to localize. Of the 18 patients who failed to localize, all 18 patients (100%) had an adenoma that fluoresced on indocyanine green imaging. The operations were performed safely with minimal blood loss and short operative times. Conclusion Indocyanine green angiography has the potential to assist surgeons in identifying parathyroid glands rapidly with minimal risk.

Background We aimed to evaluate the potential for ultrasound (US) visible biodegradable nanoshells (NS) as an alternative to wire-guided localization for nonpalpable tumors in vivo. Methods VX2 tumor was injected in bilateral thighs of 22 New Zealand rabbits and after 5 to 10 days, 1 tumor was marked with a wire as a control and the contralateral tumor was injected with 1 mL of 500 nm gas-filled silica NS under Doppler US. Tumors were excised after 24 hours. Chi-square was used for significance, P = .05. Results One rabbit was excluded on postoperative day 1 due to equipment failure, no ill effects were observed from the NS. The NS were used to localize and resect 100% of marked tissue, 4/21 wires were displaced (P Conclusions We have shown that preoperatively injected US visible silica NS can be successfully used to mark nonpalpable tumors in vivo more consistently than WL.

ABSTRACT AIM To examine national and international guidelines on sore throat management and subsequently, to explore the phenomenon of international medical graduates working in general and rural practice in New Zealand. METHOD Two separate systematic reviews were conducted that resulted in a contingent methodology. Contingent methodologies involve syntheses of data that are derived sequentially. The initial review for this study examined international sore throat guidelines and their key points. The results of this initial review resulted in the theory that international medical graduates may be unaware of the New Zealand specific sore throat guidelines and the problem of acute rheumatic fever in this country. The subsequent review examined the phenomenon of international medical graduates working in general or rural practice in New Zealand. Data sources were Medline, Google Scholar, Trip Database, and NHS Evidence, Embase and Scopus. Electronic databases were searched for relevant data published January 2000–December 2013. Additional hand searches found key references from articles and websites. RESULTS International guidelines for the management of sore throats differ from New Zealand guidelines. Of resource rich countries, New Zealand has the second highest number of international medical graduates: they may not use New Zealand specific sore throat guidelines. DISCUSSION Acute rheumatic fever is virtually eradicated in most resource rich countries. Rheumatic fever rates of among indigenous Māori and Pacifika people in New Zealand have failed to reduce over the last three decades. Knowledge and actions of international medical graduates in relation to sore throat management needs investigating. KEYWORDS Sore throats; acute rheumatic fever; clinical guidelines; international medical graduates; mixed methods review

Background: The elderly population is growing in the United States. Most clinical trials exclude patients over 80, therefore there is a paucity of data regarding the correct treatment of this group. The purpose of this systematic review was to investigate the treatment patterns for women with primary breast cancer aged 80 years old and older - modalities include surgery, chemotherapy, radiation and hormonal treatment, alone or in combination. Methods: A formal systematic review was performed with the support of the medical research librarian at the University of California San Diego Biomedical Library. PubMed and Web of Science were the databases used. A patient population of 2,947 was derived from the 16 papers reviewed. Results: Patients diagnosed over 80 were more likely to be diagnosed by clinical exam. Patients who had standard surgical treatment had an improved disease free survival. Surgical resection and radiation had a low morbidity. Conclusion: Multimodality treatment is safe in elderly women and is associated with better breast cancer specific survival outcomes.

The focus of this research was an evaluation of the impact of teacher professional development (PD) on student achievement during implementation of a reform curriculum. The PD consisted of five four‐hour workshop sessions distributed over the time teachers were implementing the reform curriculum in their classrooms. The research was conducted in a mid‐size, urban school district over the span of two years. Three groups of teachers were contrasted: teachers who continued to use the established curriculum (N = 5), teachers who implemented the reform curriculum without participating in the PD sessions (N = 5), and teachers who implemented the reform curriculum while participating in the PD sessions (N = 13). Teachers who participated in the PD had approximately a one standard deviation advantage in their students' achievement over those who did not. We collected evidence of particular features of the PD that explained the differences in student achievement. The features included: distributing the workshops t...
