Abstract Objectives Surface the urgent dilemma that healthcare delivery organizations (HDOs) face navigating the US Food and Drug Administration (FDA) final guidance on the use of clinical decision support (CDS) software. Materials and Methods We use sepsis as a case study to highlight the patient safety and regulatory compliance tradeoffs that 6129 hospitals in the United States must navigate. Results Sepsis CDS remains in broad, routine use. There is no commercially available sepsis CDS system that is FDA cleared as a medical device. There is no public disclosure of an HDO turning off sepsis CDS due to regulatory compliance concerns. And there is no public disclosure of FDA enforcement action against an HDO for using sepsis CDS that is not cleared as a medical device. Discussion and Conclusion We present multiple policy interventions that would relieve the current tension to enable HDOs to utilize artificial intelligence to improve patient care while also addressing FDA concerns about product safety, efficacy, and equity.
A Systematic Review Supporting the Endocrine Society Clinical Practice Guidelines on Vitamin D
Abstract Context Low vitamin D status is common and is associated with various common medical conditions. Objective To support the development of the Endocrine Society's Clinical Practice Guideline on Vitamin D for the Prevention of Disease. Methods We searched multiple databases for studies that addressed 14 clinical questions prioritized by the guideline panel. Of the 14 questions, 10 clinical questions assessed the effect of vitamin D vs no vitamin D in the general population throughout the lifespan, during pregnancy, and in adults with prediabetes; 1 question assessed dosing; and 3 questions addressed screening with serum 25-hydroxyvitamin D (25[OH]D). The Grading of Recommendations Assessment, Development and Evaluation approach was used to assess certainty of evidence. Results Electronic searches yielded 37 007 citations, from which we included 151 studies. In children and adolescents, low-certainty evidence suggested reduction in respiratory tract infections with empiric vitamin D. There was no significant effect on select outcomes in healthy adults aged 19 to 74 years with variable certainty of evidence. There was a very small reduction in mortality among adults older than 75 years with high certainty of evidence. In pregnant women, low-certainty evidence suggested possible benefit on various maternal, fetal, and neonatal outcomes. In adults with prediabetes, moderate certainty of evidence suggested reduction in the rate of progression to diabetes. Administration of high-dose intermittent vitamin D may increase falls, compared to lower-dose daily dosing. We did not identify trials on the benefits and harms of screening with serum 25(OH)D. Conclusion The evidence summarized in this systematic review addresses the benefits and harms of vitamin D for the prevention of disease. The guideline panel considered additional information about individuals’ and providers’ values and preferences and other important decisional and contextual factors to develop clinical recommendations.
Wild Seizing Gliomas! Time-Dependent Characteristics and Prognosis of Glioblastoma-Related Epilepsy
Characteristics and Prognosis of Tumor-Related Epilepsy During Tumor Evolution in Patients With IDH Wild-Type Glioblastoma Pallud J, Roux A, Moiraghi A, Aboubakr O, Elia A, Guinard E, Oppenheim C, Tauziede-Espariat A, Parraga E, Gavaret M, Chrètien F, Huberfeld G, Zanello M. Neurology . 2024;102(1): e207902. doi: 10.1212/WNL.0000000000207902 Background and Objectives: Tumor-related epilepsy is a well-known symptom of glioblastoma. However, the particular characteristics of epileptic seizures related to glioblastoma, isocitrate dehydrogenase (IDH)-wild-type is almost unexplored longitudinally during the whole course of the disease. We assessed tumor-related epilepsy and seizure control during tumor evolution and the prognostic significance of tumor-related epilepsy. Methods: We performed an observational, retrospective single-center study at one tertiary referral neuro-oncology surgical center (2000-2020). We included adult patients treated for a newly diagnosed supratentorial glioblastoma, IDH-wild-type with available preoperative and postoperative MRI and with available epileptic seizure status at diagnosis. To determine factors associated with tumor-related epilepsy or seizure control, univariate analyses were performed using the χ 2 or Fisher exact tests for categorical variables and the unpaired t test or Mann-Whitney rank-sum test for continuous variables. Predictors associated with tumor-related epilepsy and seizure control in unadjusted analysis were entered into backward stepwise logistic regression models. Results: One thousand six patients were enrolled. The cumulative incidence of tumor-related epilepsy increased during tumor evolution (33.1% at diagnosis, 44.7% after oncologic treatment, 52.4% at progression, and 51.8% at the end-of-life phase) and is related to tumor features (cortex involvement, no necrosis, and small volume). Uncontrolled epileptic seizures increased during tumor evolution (20.1% at diagnosis, 32.0% after oncologic treatment, 46.7% at progression, and 41.1% at the end-of-life phase). Epileptic seizure control after oncologic treatment was related to seizure features (uncontrolled before oncologic treatment and focal-to-bilateral tonic-clonic seizures) and to the extent of resection. Epileptic seizure control at tumor progression was related to seizure features (presence at diagnosis and uncontrolled after oncologic treatment) and to the time to progression. Tumor-related epilepsy at diagnosis was a predictor of a longer overall survival (adjusted hazard ratio, 0.78; 95% CI 0.67-0.90; p < 0.001) independent of age, Karnofsky Performance Status score, tumor location and volume, extent of resection, standard combined chemoradiotherapy, levetiracetam use, and MGMT promoter methylation. Discussion: The progression of tumor-related epilepsy with the evolution of glioblastoma, IDH-wild-type, and the effects of surgery on seizure control argue for proper antiseizure medication and maximal safe resection. Tumor-related epilepsy is an independent predictor of a longer survival.
Acute
Coxiella burnetii
Infection: A 10-Year Clinical Experience at a Tertiary Care Center in the United States
Abstract Background Identifying and treating patients with acute Q fever who are at an increased risk of progressing to persistent disease is crucial for preventing future complications. In this study, we share our decade-long clinical experience with acute Q fever, highlighting the challenges that clinicians encounter from making an initial diagnosis and performing risk stratification to determining the appropriate prophylaxis regimen and duration. Methods We retrieved records of adult Mayo Clinic patients (≥18 years) with positive Coxiella burnetii serology results between 1 January 2012 and 31 March 2022. Patients with Q fever anti–phase II immunoglobulin G ≥1:256 by indirect immunofluorescence were further analyzed. Results Thirty-one patients were included. Their median age was 58 years (IQR, 50–64), and the majority were men (84%). Acute hepatitis (29%), flu-like illness (25.8%), and pneumonia (16%) were the most common presentations. Thirteen patients (42%) received antibiotic prophylaxis to prevent disease progression, with significant variation in the indications and duration across physicians. The combination of doxycycline and hydroxychloroquine was the preferred regimen. Prophylaxis was administered for a median 333 days (IQR, 168–414). Four patients (13%) progressed to Q fever native valve infective endocarditis, with elevated anticardiolipin immunoglobulin G levels being the sole risk factor in 2 cases. The small sample size precluded drawing conclusions on the impact of prophylaxis in preventing disease progression. Conclusions Management of acute Q fever is complicated by the lack of comprehensive clinical guidelines leading to varied clinical practices. There is a critical need for randomized trials to establish robust evidence-based protocols for management.
Polycystic ovary syndrome and cardiovascular risk: asking the right questions
AbstractBackgroundThe potential association of long‐term oral corticosteroid (OCS) use with adverse events (AEs) in patients with bullous pemphigoid (BP) is not well characterized in a real‐world setting.ObjectivesTo evaluate the effect of OCS use and treatment duration on the incident AEs in patients with BP.MethodsThis retrospective cohort study used medical and pharmacy claims and patient enrollment data from IQVIA PharMetrics® Plus from 2006−2021. Eligible patients had a diagnosis of BP between 1 January 2006 and 30 June 2020 (≥2 claims for BP ≥ 30 days apart). Patients in the OCS cohort also had a claim for OCS use, ≥7.5 mg daily dose of prednisone or equivalent, and no claims for a nonoral systemic corticosteroid (CS) at any time during the study period. A control cohort of patients with BP not using OCS was also selected. Relative risk ratios were estimated between the incidence of AEs in OCS users with different exposure durations (short‐term, <30 days; medium‐term, 30−90 days; long‐term, >90 days) and nonusers by Poisson regression, after adjusting for age, sex, prior drug use, and baseline Charlson Comorbidity Index score within the follow‐up period.ResultsAt the 1‐year follow‐up, long‐term OCS users had a higher incidence of infections, cataract, osteoporosis, heart failure, depression or anxiety, and diabetes compared with OCS nonusers (p < 0.05). Furthermore, compared with nonusers, long‐term users had increased 1‐year risks (risk ratio; 95% confidence interval) for heart failure (2.27; 1.50−3.44), diabetes (2.05; 1.30−3.24), osteoporosis (1.72; 1.23−2.41), and infection (1.50; 1.13−1.99). Long‐term OCS users also had increased 1‐year risks for heart failure (2.00; 1.21−3.28) and osteoporosis (1.70; 1.16−2.50) compared with short‐term OCS users.ConclusionsLong‐term OCS use (≥7.5 mg) in patients with BP was associated with an increased risk of AEs. Study findings demonstrate a need for steroid‐sparing options with an improved safety profile.
Factors associated with infectious diseases fellowship academic success
The purpose of this study is to investigate the potential of using ultrasound gel to mitigate the risks of skin burn at the insertion site during microwave ablation (MWA) using non-actively cooled applicators. Ex vivo experiments in porcine tissue were conducted using two identical MWA systems. Five MWA scenarios were tested at different applicator insertion depths with an ultrasound gel layer applied at the applicator insertion sites: 8 cm insertion depth with and without 4 cm thick gel, 10 cm insertion depth with and without 2 cm thick gel, and 12 cm insertion depth without gel (reference). In all experiments, temperature elevations at the applicator insertion site on the tissue surface were recorded using thermal sensors in all experiments during 10-min MWA. The application of ultrasound gel and increasing applicator insertion depths resulted in measurable reductions in temperature elevations at the applicator insertion sites. For an insertion depth of 8 cm, the temperature elevations were 39.9 ± 4.7°C and 23.2±6.5°C without and with gel, respectively (P < 0.001). For an insertion depth of 10 cm, the temperature elevations were 20.8 ± 1.5°C and 14.4 ± 1.5°C without and with gel, respectively (P < 0.001). The maximal temperature elevations corresponding to an 8 cm insertion depth with gel were comparable with those corresponding to a 10 cm insertion depth without gel. Similarly, the maximal temperature elevations (12.2 ± 1.8°C) corresponding to 12 cm insertion depth without gel were comparable to those corresponding to 10 cm insertion depth with gel. Applying ultrasound gel at the applicator insertion site can significantly reduce temperature elevations at the tissue surface during MWA procedures.
Long‐term pneumatic stenting with positive expiratory pressure therapy for severe expiratory central airway collapse
AbstractExpiratory central airway collapse (ECAC) comprising excessive central airway collapse (EDAC) and tracheobronchomalacia. Treatment is challenging for severe cases that are not candidates for surgical management. We report a case of severe ECAC successfully managed with continuous positive airway pressure (CPAP) therapy. A 75‐year‐old female patient status post right pneumonectomy, presented with chronic cough. Dynamic bronchoscopy evaluation showed severe EDAC which improved with intraprocedural noninvasive positive pressure (NIPPV) therapy. Due to patients' comorbidities, she was not a candidate to surgical tracheobronchoplasty. Therefore, we attempted pneumatic stenting with long‐term CPAP therapy resulting in improvement of symptoms and functional capacity. The long‐term efficacy of pneumatic stenting has not been clearly established yet. Literature review of management of ECAC with NIPPV consist primarily of case reports and there is only one clinical trial being conducted to assess the efficacy of CPAP therapy in ECAC. While NIPPV arises as a sufficient alternative for management of severe ECAC, larger scale studies are needed to prove the real efficacy of NIPPV in this setting.
Listening to patients, for the patients: The COVAD Study—Vision, organizational structure, and challenges
AbstractBackgroundThe pandemic presented unique challenges for individuals with autoimmune and rheumatic diseases (AIRDs) due to their underlying condition, the effects of immunosuppressive treatments, and increased vaccine hesitancy.ObjectivesThe COVID‐19 vaccination in autoimmune diseases (COVAD) study, a series of ongoing, patient self‐reported surveys were conceived with the vision of being a unique tool to gather patient perspectives on AIRDs. It involved a multinational, multicenter collaborative effort amidst a global lockdown.MethodsLeveraging social media as a research tool, COVAD collected data using validated patient‐reported outcomes (PROs). The study, comprising a core team, steering committee, and global collaborators, facilitated data collection and analysis. A pilot‐tested, validated survey, featuring questions regarding COVID‐19 infection, vaccination and outcomes, patient demographics, and PROs was circulated to patients with AIRDs and healthy controls (HCs).DiscussionWe present the challenges encountered during this international collaborative project, including coordination, data management, funding constraints, language barriers, and authorship concerns, while highlighting the measures taken to address them.ConclusionCollaborative virtual models offer a dynamic new frontier in medical research and are vital to studying rare diseases. The COVAD study demonstrates the potential of online platforms for conducting large‐scale, patient‐focused research and underscores the importance of integrating patient perspective into clinical care. Care of patients is our central motivation, and it is essential to recognize their voices as equal stakeholders and valued partners in the study of the conditions that affect them.
