RESUMEN

BACKGROUND: As cardiovascular computed tomography (CCT) practice evolves, the demand for specialists continues to increase. However, CCT training remains variable globally with limited contemporaneous data to understand this heterogeneity. We sought to understand the role of CCT globally and the training available to underpin its use. METHODS: We performed two consecutive surveys of cardiology and radiology physicians, two years apart, utilizing the Society of Cardiovascular Computed Tomography (SCCT) website, weblinks, social media platforms, and meeting handouts to maximize our response rate. We compared United States (US)-based vs. international responses to understand global similarities and differences in practice and training in the surveys. RESULTS: 235 respondents (37% trainees and 63% educators/non-trainees) initiated the first survey with 174 (74%) completing the core survey, with 205 providing their work location (114 US and 91 international). Eighty-four percent (92/110) of educator respondents stated a need for increased training opportunities to meet growing demand. Dedicated training fellowships are heterogenous, with limited access to structural heart imaging training, despite structural scanning being performed within institutions. The lack of a standardized curriculum was identified as the main obstacle to effective CCT learning, particularly in the US, with web-based learning platforms being the most popular option for improving access to CCT training. 148 trainees initiated the second survey with 107 (72%) completing the core components (51% North America, 49% international). Only 68% said they would be able to meet their required CCT education needs via their training program. Obstacles in obtaining CCT training again included a lack of a developed curriculum (51%), a lack of dedicated training time (35%), and a lack of local faculty expertise (31%). There was regional variability in access to CCT training, and, in contrast to the first survey, most (89%) felt 1:1 live review of cases with trained/expert reader was most useful for improving CCT training alongside formal curriculum/live lectures (72%). CONCLUSIONS: There is a need to expand dedicated CCT training globally to meet the demand for complex CCT practice. Access to CCT education (didactic and 1:1 case-based teaching from expert faculty), implementation of recently published global training curricula, and increased teaching resources (web-based) as an adjunct to existing experiential learning opportunities, are all deemed necessary to address current educational shortfalls.

RESUMEN

Importance: Neuropsychiatric manifestations of COVID-19 have been reported in the pediatric population. Objective: To determine whether anti-SARS-CoV-2 and autoreactive antibodies are present in the cerebrospinal fluid (CSF) of pediatric patients with COVID-19 and subacute neuropsychiatric dysfunction. Design, Setting, and Participants: This case series includes 3 patients with recent SARS-CoV-2 infection as confirmed by reverse transcriptase-polymerase chain reaction or IgG serology with recent exposure history who were hospitalized at the University of California, San Francisco Benioff Children's Hospital and for whom a neurology consultation was requested over a 5-month period in 2020. During this period, 18 total children were hospitalized and tested positive for acute SARS-CoV-2 infection by reverse transcriptase-polymerase chain reaction or rapid antigen test. Main Outcomes and Measures: Detection and characterization of CSF anti-SARS-CoV-2 IgG and antineural antibodies. Results: Of 3 included teenaged patients, 2 patients had intrathecal anti-SARS-CoV-2 antibodies. CSF IgG from these 2 patients also indicated antineural autoantibodies on anatomic immunostaining. Autoantibodies targeting transcription factor 4 (TCF4) in 1 patient who appeared to have a robust response to immunotherapy were also validated. Conclusions and Relevance: Pediatric patients with COVID-19 and prominent subacute neuropsychiatric symptoms, ranging from severe anxiety to delusional psychosis, may have anti-SARS-CoV-2 and antineural antibodies in their CSF and may respond to immunotherapy.

RESUMEN

BACKGROUND AND OBJECTIVES: In previous studies, researchers highlight that children have higher rates of transfusion reactions than adults. However, little is known about the pediatric populations that experience reactions, and there are no reports that consider appropriateness of pediatric transfusions in relation to preventable harm. With this study, we aim to describe pediatric transfusion reactions occurring at an academic institution and to quantify transfusion reactions that resulted from inappropriate transfusion indications, thereby identifying an area of potentially preventable patient harm (PPH). METHODS: This is a case series of acute transfusion reactions in pediatric patients at a single institution from January 2018 to December 2019. We reviewed patient data, clinical documentation, and transfusion reaction reports to determine the appropriateness of transfusions and calculate PPH. RESULTS: A total 155 acute transfusion reactions occurred in 106 pediatric patients, amounting to a total reaction rate of 544 of 100 000 transfusions. In 65% of reactions, the indication for transfusion was appropriate by institutional standards; 23% had questionable indication; and 12% were not indicated. The rate of potential PPH from inappropriate transfusions was 67 of 100 000 transfusions. CONCLUSIONS: Transfusion reactions that occur during inappropriately ordered blood transfusions represent PPH. Efforts should be made to develop transfusion guidelines, standardize practice, and educate physicians to prevent transfusion-related harm.

RESUMEN

OBJECTIVE: Determine whether a regimen of fixed dose rate gemcitabine plus capecitabine is effective and tolerable for advanced pancreatic adenocarcinoma. METHODS: We performed a retrospective analysis of 62 patients with locally advanced or metastatic pancreatic adenocarcinoma treated at the University of California San Francisco between 2008 and 2016. Treatment was an alternate week schedule of fixed dose rate 1000 mg/m gemcitabine and capecitabine 1000 mg/m (58 patients), 1200 mg/m (12 patients), or 650 mg/m (1 patient) for intended 12 cycles. We evaluated overall survival (OS), progression-free survival (PFS), radiologic response, and adverse events necessitating treatment modification. RESULTS: For metastatic patients, median OS was 10.3 months (95% confidence interval [CI], 6.7-12.1 months), and PFS was 5.6 months (95% CI, 2.6-7.7 months). In locally advanced patients, OS was 12.0 months (95% CI, 4.9-17.1 months), and PFS was 5.4 months (95% CI, 2.5-9.4 months). Radiologic response for metastatic disease (42 patients) was 19% objective response, 45% stable disease, and 36% progressive disease. Treatment required modification for 22 patients due to adverse events, most frequently hand-foot syndrome (18 patients). CONCLUSIONS: Alternate week schedule of fixed dose rate gemcitabine and capecitabine was active and tolerable for advanced pancreatic adenocarcinoma. Overall survival and PFS were comparable to first-line treatments. Importantly, adverse effects appear less severe than first-line treatments.

RESUMEN

Patient-centered decision making about hot flash treatments often incorporates a balance of efficacy and side effects in addition to patient preference. This systematic review examines randomized controlled trials (RCTs) comparing at least two non-hormonal hot flash treatments in breast cancer survivors. In July 2015, PubMed, SCOPUS, CINAHL, Cochrane, and Web of Science databases were searched for RCTs comparing active, non-hormonal hot flash treatments in female breast cancer survivors. Thirteen trials were included after identifying 906 potential studies. Four trials were dose comparison studies of pharmacologic treatments citalopram, venlafaxine, gabapentin, and paroxetine. Hot flash reduction did not differ by tamoxifen or aromatase inhibitor use. Citalopram 10, 20, and 30 mg daily had comparable outcomes. Venlafaxine 75 mg daily improved hot flashes without additional side effects from higher dosing. Gabapentin 900 mg daily improved hot flashes more than 300 mg. Paroxetine 10 mg daily had fewer side effects than 20 mg. Among four trials comparing different pharmacologic treatments, venlafaxine alleviated hot flash symptoms faster than clonidine; participants preferred venlafaxine over gabapentin. Five trials compared pharmacologic to non-pharmacologic treatments. Acupuncture had similar efficacy to venlafaxine and gabapentin but may have longer durability after completing treatment and fewer side effects. We could not perform a pooled meta-analysis because outcomes were not reported in comparable formats. Clinical trial data on non-hormonal hot flash treatments provide comparisons of hot flash efficacy and other patient important outcomes to guide clinical management. Clinicians can use the information to help patients select hot flash interventions.

RESUMEN

To discover mechanisms that mediate plasticity in mammary cells, we characterized signaling networks that are present in the mammary stem cells responsible for fetal and adult mammary development. These analyses identified a signaling axis between FGF signaling and the transcription factor Sox10. Here, we show that Sox10 is specifically expressed in mammary cells exhibiting the highest levels of stem/progenitor activity. This includes fetal and adult mammary cells in vivo and mammary organoids in vitro. Sox10 is functionally relevant, as its deletion reduces stem/progenitor competence whereas its overexpression increases stem/progenitor activity. Intriguingly, we also show that Sox10 overexpression causes mammary cells to undergo a mesenchymal transition. Consistent with these findings, Sox10 is preferentially expressed in stem- and mesenchymal-like breast cancers. These results demonstrate a signaling mechanism through which stem and mesenchymal states are acquired in mammary cells and suggest therapeutic avenues in breast cancers for which targeted therapies are currently unavailable.
