Identifying SCS Trial Responders Immediately After Postoperative Programming with ECAP Dose-Controlled Closed-Loop Therapy.

INTRODUCTION: Drawbacks of fixed-output spinal cord stimulation (SCS) screening trials may lead to compromised trial outcomes and poor predictability of long-term success. Evoked compound action potential (ECAP) dose-controlled closed-loop (CL) SCS allows objective confirmation of therapeutic neural activation and pulse-to-pulse stimulation adjustment. We report on the immediate patient-reported and neurophysiologic treatment response post-physiologic CL-SCS and feasibility of early SCS trial responder prediction. METHODS: Patient-reported pain relief, functional improvement, and willingness to proceed to permanent implant were compared between the day of the trial procedure (Day 0) and end of trial (EOT) for 132 participants in the ECAP Study undergoing a trial stimulation period. ECAP-based neurophysiologic measurements from Day 0 and EOT were compared between responder groups. RESULTS: A high positive predictive value (PPV) was achieved with 98.4% (60/61) of patients successful on the Day 0 evaluation also responding at EOT. The false-positive rate (FPR) was 5.6% (1/18). ECAP-based neurophysiologic measures were not different between patients who passed all Day 0 success criteria ("Day 0 successes") and those who did not ("needed longer to evaluate the therapy"). However, at EOT, responders had higher therapeutic usage and dose levels compared to non-responders. CONCLUSIONS: The high PPV and low FPR of the Day 0 evaluation provide confidence in predicting trial outcomes as early as the day of the procedure. Day 0 trials may be beneficial for reducing patient burden and complication rates associated with extended trials. ECAP dose-controlled CL-SCS therapy may provide objective data and rapid-onset pain relief to improve prognostic ability of SCS trials in predicting outcomes. TRIAL REGISTRATION: The ECAP Study is registered with ClinicalTrials.gov (NCT04319887).

Enhancing safety culture in radiology: Key practices and recommendations for sustainable excellence.

OBJECTIVES: This review aims to explore and thematically synthesize the existing literature on safety culture within the context of radiology. The primary objective is to identify key practices that effectively strengthen safety culture, highlighting the pivotal roles of leadership, effective teamwork, and interprofessional collaboration in these efforts. The review intends to showcase actionable recommendations that are particularly relevant to the radiology setting. KEY FINDINGS: The study highlights that effective leadership is fundamental in establishing and nurturing a safety-first approach within radiology departments. Key practices for promoting a safety culture include safety huddles, leadership walkarounds, quality learning boards, intentional patient rounding (frequent patient-care provider interactions), morbidity and mortality meetings, and multidisciplinary team rounds. These practices have been found to facilitate open communication and transparency, which are crucial elements in creating a sustainable safety culture. Additionally, the study underscores the significant role of radiology managers in driving these safety initiatives and acting as facilitators for a culture of safety, focused on long-term excellence and continuous improvement. CONCLUSION: The study concludes that a multifaceted and comprehensive approach is vital for fostering a safety culture in radiology departments, with a focus on sustainable excellence in patient care. The leadership role is critical in this process, with radiology managers being instrumental in implementing and maintaining effective safety practices. IMPLICATIONS FOR PRACTICE: This study provides best practices for sustainable safety culture in radiology departments. It advocates for healthcare managers to adopt and integrate these identified practices into their operational strategies. Continuous professional development, focusing on safety and quality in patient care, and fostering a collaborative environment for open discussion and learning from safety incidents are essential for the continued advancement and excellence of healthcare services.

Human Epidermal Growth Factor Receptor 2 Overexpression/Amplification in Primary Ovarian Endometrioid Carcinoma.

Human epidermal growth factor receptor 2 (HER2) expression has become increasingly helpful in predicting responses to anti-HER2 agents in gynecological cancers. This study retrospectively analyzed HER2 expression in 48 primary ovarian endometrioid carcinomas. HER2 immunohistochemistry was performed using the Ventana platform (Clone 4B5 monoclonal predilute) following the manufacturer's protocol. HER2 expression was equivocal (score 2+) by image analysis in 2 cases (4.17%) based on the breast cancer criteria. Fluorescence in situ hybridization was negative for HER2 amplification in one case (International Federation of Gynecology and Obstetrics, grade 1) and positive in the other (International Federation of Gynecology and Obstetrics, grade 3). Our findings contribute to the growing evidence that HER2 is overexpressed in a small proportion of ovarian endometrioid carcinoma, and thus may serve as a potential therapeutic target in selected cases.

Quantitative Assessment of Subjective Symptoms and Corneal Sensitivity in Chronic Orbital Pain Patients.

PURPOSE: To objectively evaluate the subjective symptoms and characteristics of chronic orbital pain as well as to quantify sensitization of peripheral trigeminal nerves. METHODS: In this prospective cohort study, patients who previously showed a response to peripheral trigeminal nerve blocks for unilateral, idiopathic chronic orbital pain and healthy subjects completed validated questionnaires assessing headaches, neuropathic signs and symptoms, photophobia, and pain qualities. Corneal sensitivity was measured in both eyes for all subjects with a Cochet-Bonnet aesthesiometer. For pain patients, the full assessment protocol was repeated 2-4 weeks after the study injection, and corneal sensitivity was also measured 30 minutes postinjection. Outcomes assessed were headache, neuropathic pain, and photophobia scores; pain qualities; and corneal sensitivity. RESULTS: Six female chronic orbital pain patients (mean age 48.2 years) and 11 female controls (mean age 47.5) were included. The mean headache, neuropathic pain, and photophobia questionnaire scores were significantly higher for pain patients than for controls (p < 0.001). On sensory testing, 5 pain patients (83.3%) endorsed allodynia, and all 6 (100%) had hyperalgesia in the ipsilateral frontal nerve dermatome. No controls had allodynia or hyperalgesia. Corneal sensitivity was similar between eyes in pain patients and between groups. Questionnaire scores and corneal sensitivity did not change significantly after the injection. CONCLUSIONS: Chronic orbital pain patients have a measurable reduction in quality of life due to headaches and photophobia. The supraorbital and supratrochlear nerves are sensitized, resulting in cutaneous hypersensitivity in the corresponding dermatome, but corneal nerves have normal sensitivity.

Retrospective Optimization of the Hawkeye Orbital Fracture Prioritization and Evaluation Algorithms for Triaging Ophthalmic Care.

Objectives: Many orbital fracture patients are transferred to tertiary care centers for immediate ophthalmology consultation, though few require urgent ophthalmic evaluation or intervention. This overutilizes limited resources and overburdens patients and the health care system with travel and emergency department (ED) expenses. A simple, easy-to-use, clinical decision-making tool is needed to aid local EDs and triage services in effectively identifying orbital fracture patients who need urgent ophthalmic evaluation. Design: Single center, retrospective cohort study. Subjects: Orbital fracture patients aged ≥ 18 years who presented to the study institution's emergency department and received an ophthalmology consultation. Methods: Ocular injuries that required close monitoring or an intervention within the first few hours after presentation were termed urgent. Two Hawkeye Orbital Fracture Prioritization and Evaluation (HOPE) algorithms were developed to identify orbital fracture patients needing urgent evaluation; including 1 algorithm incorporating computerized tomography (CT) scans interpreted by ophthalmology (HOPE+CT). Algorithms were compared with 3 previously published protocols: the University of Texas Health Science Center at Houston (UTH), the South Texas Orbital Fracture Protocol (STOP), and Massachusetts Eye and Ear (MEE) algorithms. Main Outcome Measures: Correct triage of patients with orbital fractures who have urgent ocular or orbital conditions. Results: In the study institution's ED, 134 adult patients (145 orbits) were seen with orbital fractures in 2019. Eighteen (13.4%) had ocular or orbital conditions categorized as urgent. The HOPE tool resulted in 100% sensitivity and 78.4% specificity. The HOPE+CT tool resulted in 100.0% sensitivity and 94.0% specificity. The UTH algorithm was 91.7% sensitive and 76.5% specific. South Texas Orbital Fracture Protocol and MEE were both 100% sensitive but only 35.1% and 32.8% specific, respectively. Conclusions: The HOPE and HOPE+CT algorithms were superior or equal to the UTH, STOP, and MEE algorithms in terms of specificity while detecting all urgent cases. Implementation of a triage protocol that uses the HOPE or HOPE+CT algorithms could improve resource utilization and reduce health care costs through identification of orbital fracture patients needing urgent evaluation. An online tool that deploys the HOPE+CT algorithm in a user-friendly interface has been developed and is undergoing prospective validation before public dissemination.

To understand the experiences, needs, and preferences for supportive care, among children and adolescents (0-19 years) diagnosed with cancer: a systematic review of qualitative studies.

PURPOSE: This study aimed to understand the experiences, needs, and preferences for supportive care, among children and adolescents (0-19 years) diagnosed with cancer. METHODS: A qualitative systematic review has been reported according to PRISMA guidelines. A comprehensive search was conducted across multiple databases (APA PsycINFO, CINAHL, and Medline) and citation searches. Studies were screened according to pre-determined inclusion and exclusion criteria. Methodological quality was evaluated. Findings were extracted in relation to the context of interest of experiences, needs, and preferences of supportive care. Each finding was accompanied by a qualitative verbatim illustration representing the participant's voice. RESULTS: 4449 publications were screened, and 44 studies were included. Cancer populations represented in the included studies included lymphoma, leukaemia, brain cancer, sarcomas, and neuroblastoma. Two overarching synthesised findings were identified as (1) coping, caring relationships, communication, and impact of the clinical environment, and (2) experiences of isolation, fear of the unknown, restricted information, and changing self. Children and adolescents articulated that cancer care would be enhanced by developing a sense of control over their body and healthcare, being involved in communication and shared decision-making, and ensuring the clinical environment is age-appropriate. Many experienced a sense of disconnection from the rest of the world (including peers, school, and experiences of prejudice and bullying), and a lack of tailored support and information were identified as key unmet care needs that require further intervention. CONCLUSIONS: Children and adolescent who are diagnosed with cancer are a unique and understudied group in oncological survivorship research, with the slowest progress in improvement of care over time. This review will facilitate the development of future interventions and promote the importance of tailored support for children and adolescents at all stages of the cancer journey. IMPLICATIONS FOR CANCER SURVIVORS: Children and adolescents continue to experience a range of difficulties despite routine contact with cancer healthcare professionals. Children and adolescents should be carefully assessed about their individual circumstances and preferences for support given the clear implications from this review that "one size" does not fit all.

Pain Education and Knowledge (PEAK) Consensus Guidelines for Neuromodulation: A Proposal for Standardization in Fellowship and Training Programs.

The need to be competent in neuromodulation is and should be a prerequisite prior to completing a fellowship in interventional pain medicine. Unfortunately, many programs lack acceptable candidates for these advanced therapies, and fellows may not receive adequate exposure to neuromodulation procedures. The American Society of Pain and Neuroscience (ASPN) desires to create a consensus of experts to set a minimum standard of competence for neurostimulation procedures, including spinal cord stimulation (SCS), dorsal root ganglion stimulation (DRG-S), and peripheral nerve stimulation (PNS). The executive board of ASPN accepted nominations for colleagues with excellence in the subject matter of neuromodulation and physician education. This diverse group used peer-reviewed literature and, based on grading of evidence and expert opinion, developed critical consensus guides for training that all accredited fellowship programs should adopt. For each consensus point, transparency and recusal were used to eliminate bias, and an author was nominated for evidence grading oversight and bias control. Pain Education and Knowledge (PEAK) Consensus Guidelines for Neuromodulation sets a standard for neuromodulation training in pain fellowship training programs. The consensus panel has determined several recommendations to improve care in the United States for patients undergoing neuromodulation. As neuromodulation training in the United States has evolved dramatically, these therapies have become ubiquitous in pain medicine. Unfortunately, fellowship programs and the Accreditation Council for Graduate Medical Education (ACGME) pain program requirements have not progressed training to match the demands of modern advancements. PEAK sets a new standard for fellowship training and presents thirteen practice areas vital for physician competence in neuromodulation.

Problem-based learning in medical radiation science education: A scoping review.

INTRODUCTION: The current educational and technological environment in medical radiation science is dynamic. Educators must seek both proven and contemporary methods to ensure graduates are equipped for the clinical environment. This scoping review sought to assess the evidence regarding the value of problem-based learning (PBL) as part of medical radiation undergraduate curricula. METHODS: A systematic search of Medline, Emcare, and CINAHL was undertaken. Studies using both quantitative and qualitative methodologies were eligible if they reported the outcomes relating to PBL intervention for medical radiation science students in undergraduate education (diagnostic radiography, radiation therapy, or nuclear medicine). Outcomes included self-perceived benefits, disadvantages, and skills. Screening and data extraction was conducted independently by two reviewers. RESULTS: Eleven studies were included. Data regarding perceived benefits, perceived disadvantages, and skills were gathered. Pre-post studies demonstrated statistically significant findings suggesting better preparedness and improved attitudes for PBL students. Across institutions globally, there is evidence suggesting PBL is positively received by medical radiation students. High satisfaction was experienced amongst participants. Negative feedback included lack of resources, limitations in realism, and issues associated with groupwork. CONCLUSION: PBL may positively impact student satisfaction, knowledge acquisition, and skills, though this necessitates further research. IMPLICATIONS FOR PRACTICE: Medical radiation is an evolving discipline, and problem-based learning poses an educational tool to equip graduates with adaptive qualities.

Cystathionine-ß-synthase X proteins negatively regulate NADPH-thioredoxin reductase C activity.

Redox regulation is a posttranslational modification based on the redox reaction of protein thiols. A small ubiquitous protein thioredoxin (Trx) plays a central role in redox regulation, but a unique redox-regulatory factor called NADPH-Trx reductase C (NTRC) is also found in plant chloroplasts and some cyanobacteria. Several important functions of NTRC have been suggested, but the mechanism for controlling NTRC activity remains undetermined. Cystathionine-ß-synthase X (CBSX) proteins have been previously shown to interact with NTRC physically. Based on these observations, this study biochemically investigated the functional interaction between CBSX proteins and NTRC from Arabidopsis thaliana in vitro. Consequently, we concluded that CBSX proteins act as negative regulators of NTRC in the presence of AMP.

TRPS1 Is Differentially Expressed in a Variety of Malignant and Benign Cutaneous Sweat Gland Neoplasms.

Neoplasms of sweat glands and the breast may be morphologically and immunophenotypically similar. A recent study showed that TRPS1 staining is a highly sensitive and specific marker for breast carcinoma. In this study, we analyzed TRPS1 expression in a spectrum of cutaneous sweat gland tumors. We stained five microcystic adnexal carcinomas (MACs), three eccrine adenocarcinomas, two syringoid eccrine carcinomas, four hidradenocarcinomas, six porocarcinomas, one eccrine carcinoma-NOS, 11 hidradenomas, nine poromas, seven cylindromas, three spiradenomas, and 10 syringomas with TRPS1 antibodies. All of the MACs and syringomas were negative. Every cylindroma and two of the three spiradenomas demonstrated intense staining in cells lining the ductular spaces, with negative to relatively weak expression in surrounding cells. Of the 16 remaining malignant entities, 13 were intermediate to high positive, one was low positive, and two were negative. From the 20 hidradenomas and poromas, intermediate to high positivity was revealed in 14 cases, low positivity in three cases, and negative staining in three cases. Our study demonstrates a very high (86%) expression of TRPS1 in malignant and benign adnexal tumors that are mainly composed of islands or nodules with polygonal cells, e.g., hidradenomas. On the other hand, tumors with small ducts or strands of cells, such as MACs, appear to be completely negative. This differential staining among types of sweat gland tumors may represent either differential cells of origin or divergent differentiation and has the potential to be used as a diagnostic tool in the future.

Interprofessional education (IPE) in medical radiation science: A scoping review.

INTRODUCTION: Interprofessional education (IPE) in medical radiation education is designed to enhance both student and longer-term patient outcomes. This scoping review aims to provide an overview of the available evidence and examine the effectiveness of IPE strategies used to enhance the development of medical radiation science (MRS) students. METHODS: Medline, CINAHL, Cochrane Library and Emcare were searched for articles which employed an experimental study design to quantitatively assess the effectiveness of IPE for MRS students. Two reviewers screened and extracted relevant data independently. Critical appraisal was conducted using the JBI critical appraisal tool. RESULTS: Eighteen studies were included in this review. Diverse approaches to IPE were discovered, particularly in terms of the method of delivery, setting and duration of interventions. MRS students interact with many professions, particularly medical doctors and nurses. All studies which employed a control arm demonstrated statistically positive findings favoring IPE intervention(s). In pre-post studies, most IPE interventions reported significant positive differences after IPE was implemented. This entailed an enhanced perceived knowledge and understanding of other professions, and ability to undertake their role in the team. CONCLUSION: IPE was shown to be effective in enhancing students' perceptions and attitudes and to a limited extent, improve knowledge acquisition. Future research should assess long-term effects and patient-related outcomes. IMPLICATIONS FOR PRACTICE: IPE in a variety of formats demonstrates positive results for MRS students; however, interventions which are longer-term, conducted in small groups, and performed earlier in the educational pathway, may demonstrate greater effectiveness.

Two distinct pathogenic pathways of digital papillary adenocarcinoma - BRAF mutation or low-risk HPV infection.

Digital papillary adenocarcinoma (DPA) is a rare neoplasm that can exhibit local recurrence and distant metastasis. We present a series of eight cases of DPA showing two distinct clinical presentations, morphologies, immunophenotypes, and molecular features. Four cases were characterized by painless, slow-growing nodules located on the digits. The lesions were small, well-defined, and confined in the dermis. Histopathologically, these tumors were composed of glandular structures lined by cuboidal epithelium with luminal papillary infoldings. Only rare mitotic figures and minimal squamoid differentiation were present, and cellular necrosis was absent. All four cases were positive for the BRAF V600E immunohistochemistry but negative for p16, low-risk and high-risk HPV in situ hybridization (ISH). In contrast, the remaining four cases were characterized by painful, rapidly growing masses on the digits. These four lesions were located in the deep dermis and consisted of a solid, tightly packed papillary architecture lined by atypical epithelioid cells with inconspicuous nucleoli. Cellular necrosis, numerous mitotic figures, and prominent squamoid differentiation were seen. All cases were negative for the BRAF V600E IHC. However, they showed strong, patchy to diffuse reactivity for p16 and were positive for low-risk HPV ISH and negative for high-risk HPV ISH. Our findings suggest that the current classification of DPA encompasses tumors that show two discrete pathogenic pathways - BRAF mutation or low-risk HPV infection. DPAs with low-risk HPV infection exhibit aggressive clinical features, high-grade morphology, marked squamoid differentiation, and wild-type BRAF. DPAs with BRAF V600E have less aggressive clinical features, low-grade morphologic findings, mild to absent squamoid differentiation, and negative HPV infection.

Multiply Recurrent Composite Hemangioendothelioma of Penis with Histologic Progression to High-Grade Features.

Composite hemangioendothelioma (CHE) is a very rare low-grade malignant vascular neoplasm. Here, we present the first case of it occurring on a penis with two local recurrences over a 9 year span and its progression to a high-grade morphology.

Claudin-4 Upregulation in Acantholytic and Autoimmune-Mediated Bullous Disorders.

Claudin-4 is a key component of tight junctions, which play an important role in the formation of the epidermal barrier by forming a circumferential network in the granular layer that serves as a gatekeeper of the paracellular pathway. The aim of this study is to illustrate claudin-4 immunohistochemical staining patterns of different blistering disorders. We collected 35 cases, including two Hailey-Hailey disease, one Darier disease, three Grover disease, one acantholytic acanthoma, two warty dyskeratoma, 11 pemphigus vulgaris (PV) including six mucosal PV, and two pemphigus foliaceus. For comparison, we included five cases of normal skin, five eczema, and three bullous pemphigoid cases. Claudin-4 demonstrated weak-to-moderate expression in keratinocytes located in the stratum granulosum, keratinocytes surrounding hair follicles, and adnexal glands. Further, claudin-4 exhibited moderate-to-strong membranous staining in disrupted keratinocytes surrounding and within the acantholytic and bullous areas in 16/22 of the acantholytic cases (not seen in the six cases of mucosal PV) and all three bullous pemphigoids. This finding suggests that claudin-4 is upregulated in these conditions, which may be a compensatory response to the disrupted barrier function. This finding could shed light on the molecular mechanisms underlying disrupted barrier function in blistering disorders, independent of the specific underlying disease mechanism.

Nickel-catalyzed arylative substitution of homoallylic alcohols.

Direct coupling of unactivated alcohols remains a challenge in synthetic chemistry. Current approaches to cross-coupling of alcohol-derived electrophiles often involve activated alcohols such as tosylates or carbonates. We report the direct arylative substitution of homoallylic alcohols catalyzed by a nickel-bisphosphine complex as a facile method to generate allylic arenes. These reactions proceed via formation of an allylic alcohol intermediate. Subsequent allylic substitution with arylboroxine nucleophiles enables the formation of a variety of allylic arenes. The presence of p-methoxyphenylboronic acid is crucial to activate the allylic alcohol to achieve high product yields.

Caring for the whole person: transgender-competent HIV pre-exposure prophylaxis as part of integrated primary healthcare services in Vietnam.

INTRODUCTION: Although HIV prevalence among transgender women who have sex with men in Vietnam is high (16-18%), uptake of pre-exposure prophylaxis (PrEP) is low compared to other populations. When PrEP was initiated in 2017, gender-affirming healthcare was largely unavailable. Lack of access to competent, stigma-free healthcare is a well-documented barrier to transgender women's uptake of PrEP and primary healthcare (PHC). We aimed to demonstrate the utility of a PrEP quality improvement intervention in pinpointing and addressing barriers to PrEP use among transgender women in Vietnam. METHODS: We applied a real-world participatory continuous quality improvement (CQI) and Plan-Do-Study-Act (PDSA) methodology to ascertain barriers to PrEP uptake among transgender women and determine priority actions for quality improvement. A CQI team representing transgender women leaders, key population (KP)-clinic staff, public-sector HIV managers and project staff applied PDSA to test solutions to identified barriers that addressed the primary quality improvement outcome of the monthly change in PrEP uptake among transgender women and secondary outcomes, including month-3 PrEP continuation, the impact of offering PHC on PrEP uptake and unmet PrEP need. We utilized routine programmatic data and a descriptive cross-sectional study enrolling 124 transgender women to measure these outcomes from October 2018 to September 2021. RESULTS: Five key barriers to PrEP uptake among transgender women were identified and corresponding solutions were put in place: (1) offering gender-affirming care training to KP-clinics and community-based organizations; (2) integrating gender-affirming services into 10 KP-clinics; (3) offering PHC through five one-stop shop (OSS) clinics; (4) implementing a campaign addressing concerns related to hormone use and PrEP interactions; and (5) developing national HIV and transgender healthcare guidelines. New PrEP enrolment and month-3 PrEP continuation increased significantly among transgender women. Of 235 transgender women who initially sought healthcare other than PrEP at OSS clinics, 26.4% subsequently enrolled in PrEP. About one-third of transgender women reported unmet PrEP need, while two-thirds indicated an interest in long-acting cabotegravir. CONCLUSIONS: Offering gender-competent, integrated PHC can increase PrEP enrolment and continuation, and can be an entry-point for PrEP among those seeking care within PHC clinics. More work is needed to expand access to transgender women-led and -competent healthcare in Vietnam.

Neural activation associated with outgroup helping in adolescent rats.

Prosocial behavior, helping others in need in particular, occurs preferentially in response to the perceived distress of one's own group members or ingroup. To investigate the development of ingroup bias, neural activity during a helping test was analyzed in adolescent and adult rats. Although adults selectively released trapped ingroup members, adolescent rats helped both ingroup and outgroup members, suggesting that ingroup bias emerges in adulthood. Analysis of brain-wide neural activity, indexed by expression of the early-immediate gene c-Fos, revealed increased activity for ingroup members across a broad set of regions previously associated with empathy. Adolescents showed reduced hippocampal and insular activity and increased orbitofrontal cortex activity compared to adults. Non-helper adolescents demonstrated increased amygdala connectivity. These findings demonstrate that biases for group-dependent prosocial behavior develop with age in rats and suggest that specific brain regions contribute to prosocial selectivity, pointing to possible targets for the functional modulation of ingroup bias.

The Effect of Teprotumumab on Eyelid Position in Patients with Thyroid Eye Disease.

Teprotumumab has been shown to improve proptosis and clinical activity scores (CAS) in patients with thyroid eye disease, but little has been published regarding its effects on eyelid retraction. The purpose of this work was to evaluate changes in eyelid position in thyroid eye disease patients after teprotumumab. Eight patients completed eight cycles of teprotumumab. Data collected included exophthalmometry; clinical activity scores; margin reflex distance (MRD) 1; MRD2; and pre-, during, and posttreatment photographs. ImageJ analysis was also used to evaluate eyelid position in photographs. Proptosis significantly improved in 15 of 16 orbits [mean 4.75 ± 2.07 mm reduction (P = 0.0001) in study orbits and mean 3.00 ± 2.14 mm reduction (P = 0.0048) in nonstudy orbits]. CAS was significantly reduced (pretreatment mean 4.88 mm and posttreatment mean 1.88 mm, P = 0.006). MRD1 decreased in 11 of 16 orbits and increased in five orbits (P = 0.18 in study orbits and P = 0.22 in nonstudy orbits). MRD2 decreased in six of 16 orbits and increased in eight orbits (P = 0.49 in study orbits and P = 0.43 in nonstudy orbits). Patients exhibited variable changes in eyelid position with teprotumumab. There was a statistically insignificant decrease in MRD1 after teprotumumab. Proptosis reduction led to unpredictable changes in MRD1 and MRD2. Severity of eyelid retraction did not correlate with clinical activity score response to teprotumumab. There are inherent difficulties in evaluating eyelid position in thyroid eye disease, which may necessitate a paradigm shift in how patients are examined, measured, and photographed.

Exploring the diagnostic utility of genome sequencing for fetal congenital heart defects.

OBJECTIVE: The diagnostic yield for congenital heart defects (CHD) with routine genetic testing is around 10%-20% when considering pathogenic CNVs or aneuploidies as positive findings. This is a pilot study to investigate the utility of genome sequencing (GS) for prenatal diagnosis of CHD. METHODS: Genome sequencing (GS, 30X) was performed on 13 trios with CHD for which karyotyping and/or chromosomal microarray results were non-diagnostic. RESULTS: Trio GS provided a diagnosis for 4/13 (30.8%) fetuses with complex CHDs and other structural anomalies. Findings included pathogenic or likely pathogenic variants in DNAH5, COL4A1, PTPN11, and KRAS. Of the nine cases without a genetic etiology by GS, we had outcome follow-up data on eight. For five of them (60%), the parents chose to keep the pregnancy. A balanced translocation [46,XX,t(14; 22)(q32.33; q13.31)mat] was detected in a trio with biallelic DNAH5 mutations, which together explained the recurrent fetal situs inversus and dextrocardia that was presumably due to de novo Phelan-McDermid syndrome. A secondary finding of a BRCA2 variant and carrier status of HBB, USH2A, HBA1/HBA2 were detected in the cohort. CONCLUSIONS: GS expands the diagnostic scope of mutation types over conventional testing, revealing the genetic etiology for fetal heart anomalies. Patients without a known genetic abnormality indicated by GS likely opted to keep pregnancy especially if the heart defect could be surgically repaired. We provide evidence to support the application of GS for fetuses with CHD.
