Continuous Fetal Cardiac Monitoring During Fetoscopic Myelomeningocele Repair and Relationship to Spectral Doppler Changes.

INTRODUCTION: No evidence-based protocols exist for fetal cardiac monitoring during fetoscopic myelomeningocele (fMMC) repair and intraprocedural spectral Doppler data is limited. We determined the feasibility of continuous fetal echocardiography during fMMC repair and correlated Doppler changes with qualitative fetal cardiac function during each phase of fMMC repair. METHODS: Patients undergoing fMMC repair had continuous fetal echocardiography interpreted in real-time by pediatric cardiology. Fetal data included fetal heart rate (FHR), qualitative cardiac function, mitral and tricuspid valve inflow waveforms, and umbilical artery (UA), umbilical vein (UV), ductus arteriosus (DA) and ductus venosus (DV) Dopplers. RESULTS: UA abnormalities were noted in 14/25 patients, UV abnormalities were observed in two patients, and DV and DA abnormalities were each noted in 4 patients. Qualitative cardiac function was normal for all patients with the exception of one with isolated left ventricular dysfunction during myofascial flap creation, concurrent with an abnormal UA flow pattern. All abnormalities resolved by the first postoperative day. CONCLUSIONS: Continuous fetal echocardiography was feasible during all fMMC repairs. Spectral Doppler changes in the UA were common during fMMC procedures but qualitative cardiac dysfunction was rare. Abnormalities in the UV, DV and DA Dopplers, FHR, and cardiac function were less common findings.

Variation in prenatal surveillance and management of anti-SSA/Ro autoantibody positive pregnancies.

OBJECTIVE: To describe international surveillance and treatment strategies for managing anti-SSA/Ro autoantibody positive pregnancies. STUDY DESIGN: An electronic REDCap questionnaire was distributed to Fetal Heart Society and North American Fetal Therapy Network members which queried institution-based risk stratification, surveillance methods/frequency, conduction abnormality treatments, and postnatal anti-SSA/Ro pregnancy assessment. RESULTS: 101 responses from 59 centers (59% US, 17% international) were collected. Most (79%) do not risk stratify pregnancies by anti-SSA/Ro titer; those that do use varied cutoff values. Many pregnant rheumatology patients are monitored for cardiac abnormalities regardless of maternal anti-SSA/Ro status. Surveillance strategies were based on maternal factors (anti-SSA/Ro status 85%, titer 25%, prior affected child 79%) and monitoring durations varied. Most respondents treat 2° and 3° fetal atrioventricular block, commonly with dexamethasone and/or IVIG. CONCLUSIONS: Wide variation exists in current fetal cardiac surveillance and treatment for anti-SSA/Ro autoantibody positive pregnancies, highlighting the need for evidence-based protocols to optimize care.

Understanding the Care Journey and Needs of Advanced Fetal Care Center Patients.

Introduction This study describes the parental perspective of the management and care experience of patients experiencing a pregnancy complicated by a fetal diagnosis to inform more supportive patient-centered care. Methods We conducted a prospective multicenter qualitative patient experience study at three metropolitan children's hospitals' advanced fetal care centers: the Cincinnati, Colorado, and Midwest Fetal Care Centers. Data were collected from pregnant patients who experienced the management of a pregnancy complicated by a fetal anomaly. Clinical journey data were obtained using qualitative research methods in post-birth semistructured interviews. We assembled a generalizable patient journey map to identify the general clinical encounters, and present common participant experiences from diagnosis to post-birth discharge. Results Fifteen families were interviewed; four experienced a loss (27%). Common experiences of trust, education, surrounding support, consistency, and abandonment emerged across all centers. Participant trust in their care team was gained through strong referrals, institutional reputation, and transparent outcomes. Unconditional care team support and continual reassurance was paramount to maintaining participant trust throughout their care journey. Participants appreciated both active and passive educational techniques at clinical touch points. A consistent point of contact assured participants. All families mentioned they felt close to their fetal care team; however, several mentioned that the post-birth transition of care created feelings of abandonment. Conclusions When a family understands the clinical information and feels supported, they are empowered and confident in their ability to navigate their circumstances. Listening to the parental perspective is important to delivering sensitive fetal care.

Placental Location in Maternal-Fetal Surgery for Myelomeningocele.

INTRODUCTION: Uterine incision based on the placental location in open maternal-fetal surgery (OMFS) has never been evaluated in regard to maternal or fetal outcomes. OBJECTIVE: The aim of this study was to investigate whether an anterior placenta was associated with increased rates of intraoperative, perioperative, antepartum, obstetric, or neonatal complications in mothers and babies who underwent OMFS for fetal myelomeningocele (fMMC) closure. METHODS: Data from the international multicenter prospective registry of patients who underwent OMFS for fMMC closure (fMMC Consortium Registry, December 15, 2010-June 31, 2019) was used to compare fetal and maternal outcomes between anterior and posterior placental locations. RESULTS: The placental location for 623 patients was evenly distributed between anterior (51%) and posterior (49%) locations. Intraoperative fetal bradycardia (8.3% vs. 3.0%, p = 0.005) and performance of fetal resuscitation (3.6% vs. 1.0%, p = 0.034) occurred more frequently in cases with an anterior placenta when compared to those with a posterior placenta. Obstetric outcomes including membrane separation, placental abruption, and spontaneous rupture of membranes were not different among the 2 groups. However, thinning of the hysterotomy site (27.7% vs. 17.7%, p = 0.008) occurred more frequently in cases of an anterior placenta. Gestational age (GA) at delivery (p = 0.583) and length of stay in the neonatal intensive care unit (p = 0.655) were similar between the 2 groups. Fetal incision dehiscence and wound revision were not significantly different between groups. Critical clinical outcomes including fetal demise, perinatal death, and neonatal death were all infrequent occurrences and not associated with the placental location. CONCLUSIONS: An anterior placental location is associated with increased risk of intraoperative fetal resuscitation and increased thinning at the hysterotomy closure site. Individual institutional experiences may have varied, but the aggregate data from the fMMC Consortium did not show a significant impact on the GA at delivery or maternal or fetal clinical outcomes.

Fetal Non-Ovarian Abdominopelvic Cystic Lesions: A Single-Center Report.

INTRODUCTION: There is a paucity of reports describing the clinical course and likely postnatal outcomes of prenatally identified simple cystic abdominopelvic lesions which are not associated with the ovary. OBJECTIVE: The aim of this study was to describe the natural history and postnatal outcomes of prenatally discovered abdominopelvic cystic lesions seen at our center. METHODS: This study is a retrospective review of all newborns with prenatally discovered non-ovarian simple cystic abdominal or pelvic lesions (September 2012-December 2018). Prenatal solid organ involvement, lesion size, and postnatal clinical outcomes are described. RESULTS: Sixty-six patients with 68 cystic lesions were identified; 22 patients with 24 lesions met the defined study criteria and were included. Eleven (46%) resolved prenatally, while 5 (21%) resolved by 18 months of age. Of the 10 lesions associated with an organ, 4 (40%) resolved prenatally. Of the remaining 14 lesions not associated with a solid organ, 7 (50%) resolved prenatally. Seven lesions (29%) required postnatal surgical intervention. Larger maximum prenatal lesions tended toward postnatal surgical intervention (one-way ANOVA: p = 0.072). CONCLUSIONS: The majority of simple non-ovarian cystic abdominopelvic lesions at our center resolved in the perinatal period. Due to the low frequency of these lesions at fetal centers, a larger multicenter study based on a consistent monitoring protocol should be undertaken to better describe the resolution patterns of simple non-ovarian cystic lesions for improved prenatal counseling.

Clinical Diagnosis of Infection in Surgical Intensive Care Unit: You're Not as Good as You Think!

Background: Because of the everincreasing costs and the complexity of institutional medical reimbursement policies, the necessity for extensive laboratory work-up of potentially infected patients has come into question. We hypothesized that intensivists are able to differentiate between infected and non-infected patients clinically, without the need to pan-culture, and are able to identify the location of the infection clinically in order to administer timely and appropriate treatment. Methods: Data collected prospectively on critically ill patients suspected of having an infection in the surgical intensive care unit (SICU) was obtained over a six-month period in a single tertiary academic medical center. Objective evidence of infection derived from laboratory or imaging data was compared with the subjective answers of the three most senior physicians' clinical diagnoses. Results: Thirty-nine critically ill surgical patients received 52 work-ups for suspected infections on the basis of signs and symptoms (e.g., fever, altered mental status). Thirty patients were found to be infected. Clinical diagnosis differentiated infected and non-infected patients with only 61.5% accuracy (sensitivity 60.3%; specificity 64.4%; p = 0.0049). Concordance between physicians was poor (κ = 0.33). Providers were able to predict the infectious source correctly only 60% of the time. Utilization of culture/objective data and SICU antibiotic protocols led to overall 78% appropriate initiation of antibiotics compared with 48% when treatment was based on clinical evaluation alone. Conclusion: Clinical diagnosis of infection is difficult, inaccurate, and unreliable in the absence of culture and sensitivity data. Infection suspected on the basis of signs and symptoms should be confirmed via objective and thorough work-up.

Investigating Clinical and Cost Burdens of Law Enforcement-Related K9 Injuries: The Impact of "the Bite" on a Community Hospital.

The decision to introduce canines (K9s) to a law enforcement (LE) agency does not typically involve the evaluation of the fiscal or clinical impact on local hospitals. This study compared injury, cost, and care associated with K9s to a common nonlethal force method, the Thomas A Swift Electrical Rifle (TASER), to highlight the cost and resources required to treat both patient types. Patients treated for LE-related K9 and TASER injuries at a Level I community-based trauma center (2011-2016) were evaluated for level of care required (e.g., surgeon/specialist), clinical interventions, proxy medical costs, and length of stay (LOS). Nearly one-third of K9 patients required tertiary-level medical care. The cost of treating the K9-inflicted injuries (n = 75) was almost twice as costly as care for patients subdued with a TASER (n = 80); the K9 patients had significantly (one-tailed t tests) higher medical costs (P = 0.036), required more medical procedures (P = 0.014), and had longer LOS (P = 0.0046) than the TASER patients. Patients with K9 injuries had higher acuity and were significantly more expensive to treat with longer LOS than TASER injuries. LE agencies considering establishing and operating a K9 unit should initiate discussions with their local medical first responders and health-care facilities regarding the capabilities to treat severe K9 injuries to ensure adequate resource allocation.

STATISTICAL COMPARISON OF AFIRMA GSC AND AFIRMA GEC OUTCOMES IN A COMMUNITY ENDOCRINE SURGICAL PRACTICE: EARLY FINDINGS.

OBJECTIVE: The Veracyte Afirma Gene Expression Classifier (GEC) has been the most widely used negative predictive value molecular classifier for indeterminate cytology thyroid nodules since January 2011. To improve the specificity and further reduce unnecessary thyroid surgeries, a second-generation assay (Afirma Genetic Sequence Classifier [GSC]) was released for clinical use in August 2017. We report 11 months of clinical outcomes experience with the GSC and compare them to our 6.5-year experience with the GEC. METHODS: We searched our practice registry for FNAB nodules with Afirma results from January 2011through June 2018. GEC versus GSC results were compared overall, in oncocytic and nononcocytic aspirates and by pathologic outcomes. RESULTS: GSC identified less indeterminate cytology nodules as suspicious (38.8%; 54/139) when compared to GEC (58.4%; 281/481). There was a decrease of in the percentage of oncocytic fine-needle aspiration thyroid biopsy (FNAB) subjects classified as suspicious in the GSC group, with 86 of 104 oncocytic indeterminates (82.7%) classified as suspicious by GEC and 12 of 34 (35.3%) classified as suspicious by GSC. The surgery rate in patients with oncocytic aspirates fell from 56% in the GEC group to 31% in the GSC-evaluated group (45%). Pathology analysis demonstrated a false-negative percentage for an incomplete surgical group of 9.5% for GEC and 1.2% for GSC. CONCLUSION: Our GSC data suggest that the GSC further reduces surgery in indeterminate thyroid nodules by improving the specificity of Afirma technology without compromising sensitivity. A primary determinant for this change is a significant improvement in the specificity of the Afirma GSC test in oncocytic FNAB aspirates. ABBREVIATIONS: FNAB = fine-needle aspiration biopsy; GEC = Gene Expression Classifier; GSC = Genetic Sequence Classifier.

Pyeloduodenal Fistula in Xanthogranulomatous Pyelonephritis: A Series of Two Cases.

Xanthogranulomatous inflammation, characterized by destruction and replacement of tissues with chronic inflammatory cells, including foamy histiocytes and hemosiderin-laden macrophages, is uncommon. In patients with xanthogranulomatous pyelonephritis, inflammation may extend from the kidney to the overlying duodenum, creating a pyeloduodenal fistula that further complicates medical and surgical management. We present two cases with recurrent kidney infections who each ultimately received a nephrectomy and repair of their duodenal fistula.

Prospective study of myelin water fraction changes after mild traumatic brain injury in collegiate contact sports.

OBJECTIVE: Mild traumatic brain injury (mTBI) in athletes, including concussion, is increasingly being found to have long-term sequelae. Current imaging techniques have not been able to identify early damage caused by mTBI that is predictive of long-term symptoms or chronic traumatic encephalopathy. In this preliminary feasibility study, the authors investigated the use of an emerging magnetic resonance imaging (MRI) technique, multicomponent driven equilibrium single pulse observation of T1 and T2 (mcDESPOT), in visualizing acute and chronic white matter changes after mTBI in collegiate football and rugby players. METHODS: This study was a nonrandomized, nonblinded prospective trial designed to quantify changes in the myelin water fraction (MWF), used as a surrogate MRI measure of myelin content, in a group of male collegiate football and rugby players, classified here as a contact sport player (CSP) cohort, at the time of mTBI diagnosis and 3 months after injury when the acute symptoms of the injury had resolved. In addition, differences in the MWF between the CSP cohort and a control cohort of noncontact sport players (NCSPs) were quantified. T-tests and a threshold-free cluster enhancement (TFCE) statistical analysis technique were used to identify brain structures with significant changes in the MWF between the CSP and NCSP cohorts and between immediately postinjury and follow-up images obtained in the CSP cohort. RESULTS: Brain MR images of 12 right-handed male CSPs were analyzed and compared with brain images of 10 right-handed male NCSPs from the same institution. A comparison of CSP and NCSP baseline images using TFCE showed significantly higher MWFs in the bilateral basal ganglia, anterior and posterior corpora callosa, left corticospinal tract, and left anterior and superior temporal lobe (p < 0.05). At the 3-month follow-up examination, images from the CSP cohort still showed significantly higher MWFs than those identified on baseline images from the NCSP cohort in the bilateral basal ganglia, anterior and posterior corpora callosa, and left anterior temporal lobe, and also in the bilateral corticospinal tracts, parahippocampal gyrus, and bilateral juxtapositional (previously known as supplemental motor) areas (p < 0.05). In the CSP cohort, a t-test comparing the MWF at the time of injury and 3 months later showed a significant increase in the overall MWF at follow-up (p < 0.005). These increases were greatest in the bilateral basal ganglia and deep white matter. MWF decreases were seen in more superficial white matter (p < 0.005). CONCLUSIONS: In this preliminary study, MWF was found to be increased in the brains of CSPs compared with the brains of controls, suggesting acute/chronic MWF alterations in CSPs from previous injuries. Increases in the MWF were also demonstrated in the brains of CSPs 3 months after the players sustained an mTBI. The full clinical significance of an increased MWF and whether this reflects axon neuropathology or disorderly remyelination leading to hypermyelination has yet to be determined.

COMMUNITY ENDOCRINE SURGICAL EXPERIENCE WITH FALSE-NEGATIVE AFIRMA GEC® RESULTS: 2011-2017.

OBJECTIVE: Afirma Gene Expression Classifier® (Afirma GEC) molecular analysis (Veracyte, Inc, San Francisco, CA) is a negative predictive value test developed to reduce the number of thyroidectomies in thyroid nodule patients with indeterminate cytology. GEC technology has reportedly reduced unnecessary thyroid surgery, but few studies have examined Afirma GEC false-negative rates, since usually patients with GEC benign nodules do not undergo surgery for definitive diagnosis. Occasionally, Afirma GEC benign patients require removal of their thyroid nodules for other reasons; this work describes the incidence of malignancy and noninvasive follicular thyroid neoplasms with papillary-like nuclear features (NIFTP) in this population. METHODS: We reviewed our community endocrine surgical practice database for patients who had undergone thyroid surgery from January 2011 through April 2017 despite benign Afirma GEC results. RESULTS: Afirma GEC testing was completed for 475 patients during the study period. Surgery was clinically indicated for other reasons in 42 of the 193 patients (22%) with Afirma GEC benign results. Malignancy or NIFTP in the targeted nodule was found in the final histologic evaluation of 14 of the 42 Afirma GEC benign surgical patients. The Afirma GEC false-negative percentage for our incomplete surgical group (FNP-ISG), defined as the surgically proven false negatives divided by the total Afirma GEC benign patients, was 7.3%. CONCLUSION: Our high surgical rate in Afirma GEC benign nodules reveals an FNP-ISG of 7.3% in our community endocrine surgical patient population; this value exceeds the 5.7% reported in the multicenter 2012 Afirma GEC validation study. ABBREVIATIONS: Afirma GEC = Afirma Gene Expression Classifier; FNA = fine-needle aspiration; FNP = false-negative percentage; FNP-ISG = false-negative percentage for an incomplete surgical group; NIFTP = noninvasive follicular thyroid neoplasms with papillary-like nuclear features.

Trauma and Intensive Care Nursing Knowledge and Attitude of Foley Catheter Insertion and Maintenance.

In the acute care setting, the majority of urinary tract infections are associated with indwelling urinary catheters. Despite guidelines for proper use, catheter-associated urinary tract infections (CAUTIs) continue to occur in critically ill/injured patients. There is a paucity of data on the translation between CAUTI prevention education and behavioral change. This project evaluated nurse's clinical knowledge and attitude toward Foley catheter insertion and maintenance to determine the benefits of addressing gaps in knowledge and inconsistencies in attitude through education.A prospective cohort study was conducted with registered nurses from the emergency room, trauma/surgical, and medical intensive care units. Participant's clinical knowledge and attitude toward Foley catheter usage and CAUTIs were evaluated using a 20-question survey tool before and after a CAUTI education program.Forty-eight nurses completed the presurvey, educational training, and postsurvey. The mean postsurvey score was significantly higher (86.9 ± 8.3%) than the presurvey score (76.0 ± 12.3%) for the knowledge section of the survey. There was no marked difference in participant attitude following the educational training, with mean presurvey and postsurvey scores of 91.3 ± 7.0% and 89.8 ± 5.3%, respectively. After the course, participants were more confident in their clinical knowledge; however, perception regarding CAUTI prevention did not improve. A series of unannounced rounding observations before and after the intervention showed an improvement in proper Foley catheter maintenance.Catheter-associated urinary tract infection prevention education was an effective countermeasure to address gaps in clinical knowledge, but modifying attitudes was difficult to achieve. In the short term, the training appeared to improve proper maintenance in clinical practice.

Lightning Burns and Electrical Trauma in a Couple Simultaneously Struck by Lightning.

More people are struck and killed by lightning each year in Florida than any other state in the United States. This report discusses a couple that was simultaneously struck by lightning while walking arm-in-arm. Both patients presented with characteristic lightning burns and were admitted for hemodynamic monitoring, serum labs, and observation and were subsequently discharged home. Despite the superficial appearance of lightning burns, serious internal electrical injuries are common. Therefore, lightning strike victims should be admitted and evaluated for cardiac arrhythmias, renal injury, and neurological sequelae.
