Migraine headache in patients with spontaneous coronary artery dissection: A report of the iSCAD Registry.

INTRODUCTION: Spontaneous coronary artery dissection (SCAD) is a nonatherosclerotic cause of myocardial infarction. Migraine headache has been reported to be common among patients with SCAD, but the degree of migraine-related disability has not been quantified. METHODS: Clinical data and headache variables were obtained from the baseline assessment of the prospective, multicenter iSCAD Registry. Migraine-related disability was quantified using the self-reported Migraine Disability Assessment (MIDAS). Demographic, clinical, psychosocial, and medical characteristics from data entry forms were compared between patients with and without migraine. RESULTS: Of the 773 patients with available data, 46% reported previous or current migraines. Those with migraines were more likely to be women (96.9% vs 90.3%, p = 0.0003). The presence of underlying carotid fibromuscular dysplasia was associated with migraine (35% vs 27%, p = 0.0175). There was not a significant association with carotid artery dissection and migraine. Current migraine frequency was less than monthly (58%), monthly (24%), weekly (16%), and daily (3%). Triptan use was reported in 32.5% of patients, and 17.5% used daily migraine prophylactic medications. Using the MIDAS to quantify disability related to migraine, 60.2% reported little or no disability, 14.4% mild, 12.7% moderate, and 12.7% severe. The mean MIDAS score was 9.9 (mild to moderate disability). Patients with SCAD had higher rates of depression and anxiety (28.2% vs 17.7% [p = 0.0004] and 35.3% vs 26.7% [p = 0.0099], respectively). CONCLUSIONS: Migraines are common, frequent, and a source of disability in patients with SCAD. The association between female sex, anxiety, and depression may provide some insight for potential treatment modalities.

The Expression of PRAME as an Aid for Diagnosis and Evaluation of Histologic Margins of Intraepidermal Cutaneous Melanoma in Xeroderma Pigmentosum Patients.

Xeroderma Pigmentosum (XP) is a genetic disorder characterized by photosensitivity, dyschromia, and high risk of skin cancer. From a clinical and histologic view, it can be difficult to diagnose cutaneous melanoma (CM) in XP patients and to define its resection margins. We aimed to study the role of PRAME (PReferentially Expressed Antigen in MElanoma) in differentiating intraepidermal CM from superficial atypical melanocytic proliferation of uncertain significance (SAMPUS) and evaluating the histological margins of CMs. We included XP patients. melanocitic and nonmelanocytic lesions with adjacent skin, and, as control groups, sun-damaged skin from non-XP individuals. Melanocytic lesions with a consensus diagnosis were grouped into CM, SAMPUS, or benign. The selected samples were PRAME-immunoshistochemically stained, and the ratio between immuno-positive cells/mm was recorded, according to Olds and colleagues for intraepidermal lesions. Lezcano and colleagues' method was used for intradermal lesions. Clinical data from XP patients were reviewed. All 9 patients were alive and well at the study closure, even those who developed melanoma metastases. Positive/diffuse PRAME expression was found in 29% (7/24) of intraepidermal CMs and 20% (1/5) SAMPUS samples. All 103 XP control samples and 24 adjacent lesions skin of non-XP patients were PRAME negative. This was a single-center and retrospective study, using a relatively small sample, limiting our conclusions. In XP patients' lesions, PRAME expression could help in the setting of challenging melanocytic tumors and surgical margins evaluation. It is also possible that the method can avoid overdiagnosis and, consequently, more aggressive treatment recommendation in unequivocal CM cases.

ACR Appropriateness Criteria® Screening for Abdominal Aortic Aneurysm.

Abdominal aortic aneurysm (AAA) is a significant vascular disease found in 4% to 8% of the screening population. If ruptured, its mortality rate is between 75% and 90%, and it accounts for up to 5% of sudden deaths in the United States. Therefore, screening of AAA while asymptomatic has been a crucial portion of preventive health care worldwide. Ultrasound of the abdominal aorta is the primary imaging modality for screening of AAA recommended for asymptomatic adults regardless of their family history or smoking history. Alternatively, duplex ultrasound and CT abdomen and pelvis without contrast may be appropriate for screening. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

The complexity of online patient education materials for wound care strategies: A readability analysis.

BACKGROUND: In the United States, over 6 million people are affected by chronic wounds. Patients often rely on the Internet for treatment information; however, these educational materials typically exceed the average eighth-grade health literacy level. This study aimed to assess the readability and language accessibility of online patient education materials on wound care strategies. METHODS: A search was conducted on Google for articles related to wound care strategies. The first 12 unique websites from each search strategy were selected for further analysis. Readability was assessed using 11 tests, with the mean scores calculated for each. RESULTS: A total of 66 articles pertaining to wound care strategies were retrieved from 43 websites. All articles had an average reading grade level of 13.5 ± 2.5 and an average reading age of 18.7 ± 2.5 years. Websites were categorized by the following sources: academic (34.9%), reagent/biologic manufacturers (27.9%), wound care (18.6%), news media organizations (14%), and other (4.7%). Flesch Reading Ease Score, graded from 0 for most difficult to 100 for least difficult, was found to be highest for academic websites (44.2, P = .01) and lowest for news media websites (24.9, P = .01). Academic websites were available in the more languages compared to all other website categories (P < .01). CONCLUSION: Online materials related to wound care strategies often exceed the National Institute of Health recommended eighth-grade reading level. This study emphasizes the need for healthcare providers to create more accessible educational materials to address the gap in health literacy and optimize patient care.

Gender Is a Spectrum: Evaluating Current and Novel Ways to Inquire About Gender Identity in the Health Care Setting.

PURPOSE: The use of visuals to inquire about gender in the clinical setting has been rare. We developed a survey that included a visual spectrum to assess perceptions about the most and least inclusive ways of inquiring about gender in patients with gender dysphoria. METHODS: The survey included a multiple-choice question (MCQ), free-response question, and a visual spectrum on which respondents were asked to select one box that best depicts their gender. The survey was administered to all patients diagnosed with gender dysphoria at our institution between April and June 2022. RESULTS: A total of 223 of 856 patients responded. Those with more masculine gender identities selected boxes near the visual spectrum corner of "man," whereas responses were more variable for more feminine genders. The free-response question was identified by 59% of respondents as the most inclusive. The MCQ was identified as least inclusive by 70.4%. The visual spectrum was considered the most inclusive method by the majority of patients who self-identified as woman and demiwoman/demifemale. Being asked about pronouns was extremely or very important in the health care setting for 52% of respondents, but 68.6% indicated that they are rarely or sometimes asked about their pronouns in this setting. CONCLUSIONS: The traditional MCQ format for self-identifying gender may be lacking in inclusivity and fails to represent the nuances of gender identity. Free response was considered the most inclusive way to inquire about gender among our respondents. These findings highlight the importance of formatting gender identity questionnaires to foster inclusivity for transgender patients.

Endoscopic Repair of Internal Carotid Artery Injury with a Lateral Tongue Muscle Patch Graft: Novel Technique and Literature Review.

Objectives Iatrogenic injury to the internal carotid artery (ICA) is one of the most catastrophic complications of endoscopic sinus and skull base surgery. Previous research has shown that packing with a crushed muscle graft at the injury site can be an effective management technique to control bleeding and prevent the need for ICA sacrifice. Here, we describe a novel and readily available repair donor site-an autologous lateral tongue muscle patch. Design Three representative cases of a successful repair of ICA injuries using a lateral tongue muscle patch are included in this study. The graft measured approximately 2 × 3 cm and was taken from the lateral intrinsic tongue musculature. We describe the harvest of the graft, its advantages, and the details of operative repair. Results The lateral tongue provides a large and readily accessible source of muscle within the surgical field that can be quickly harvested during an endoscopic procedure. For the first case, an expanding parasellar ICA pseudoaneurysm was managed with a tongue muscle patch and nasal packing. In the second case, a cavernous ICA injury was sustained during craniopharyngioma resection. Case three involved an ICA injury during endonasal debridement of invasive fungal rhinosinusitis. None of the patients required embolization or neurovascular stenting. Postoperative angiograms and serial computed tomography angiograms showed complete resolution of the pseudoaneurysm, and the patients continued to do well at least 1 year after repair. Conclusion Lateral tongue muscle graft is an effective and efficient method to manage ICA injuries during endoscopic endonasal surgery. Advantages include the speed of harvest, donor site being readily accessible in the surgical field, and low donor site morbidity. It should be added to the repertoire of possible donor sites for addressing catastrophic sinonasal bleeding.

Small Hemothoraces Not Drained on Admission: Initial Volume Predicts Need for Intervention.

BACKGROUND: Unlike large hemothoraces (HTX), small HTX after blunt trauma may be observed without drainage. We aimed to study if there were risk factors that would predict the need for intervention in initially observed small HTX. METHODS: A retrospective review of patients with blunt traumatic HTX from 2016 to 2022 was performed. Patients with small HTX (pleural fluid volume <400 mL on admission chest computerized tomography [CT]) were included. Patients were considered as being "initially observed" if there was no intervention for the HTX within 48 hours after admission. Primary outcome was any HTX-related intervention (open, thoracoscopic or percutaneous procedures) occurring after 48 hours and up to 6 months after injury. Univariable and multivariable statistical analyses were employed. A P-value of <.05 was considered significant. RESULTS: Of 335 patients with HTX, 188 (59.6%) met inclusion criteria. Median (interquartile range) HTX volume was 90 (36-134) ml. One hundred and twenty-seven (68%) were initially observed. Of these, 31 (24%) had the primary outcome. These patients had a larger HTX volume (median, 129 vs 68 mL, P = .0001), and number of rib fractures (median, 7 vs 4, P = .0002) compared to those without the primary outcome. Chest-related readmission occurred in 8 (6%) with a median of 20 days from injury. Of these, 7 required an HTX-related intervention. Logistic regression analysis found that both the number of rib fractures and HTX volume independently predicted the primary outcome. CONCLUSION: For small HTX initially observed, number of rib fractures and initial volume predicted delayed HTX-related intervention.

Paraspinous Muscle Flaps in Complex Pediatric Spine Surgeries: A 12-Year Single Institution Experience.

PURPOSE: The benefits of paraspinous flaps in adult complex spine surgery patients are established in the literature; however, their use in pediatric patients has not been well described. This study compares clinical outcomes with and without paraspinous muscle flap closure in pediatric patients who have undergone spine surgery. METHODS: We conducted a retrospective review of all pediatric spine surgeries at the University of California, San Francisco from 2011 to 2022. Patients were divided into 2 cohorts based on whether the plastic surgery service closed or did not close the wound with paraspinous muscle flaps. We matched patients by age, American Society of Anesthesiology classification, prior spinal surgical history, and diagnosis. Surgical outcomes were compared between the 2 cohorts. RESULTS: We identified 226 pediatric patients who underwent at least one spinal surgery, 14 of whom received paraspinous flap closure by plastic surgery. They were matched in a 1:4 ratio with controls (n = 56) that did not have plastic surgery closure. The most common indication for plastic surgery involvement was perceived complexity of disease by the spine surgeon with concern for inadequate healthy tissue coverage (78.6%), followed by infection (21.4%). Postoperative complications were similar between the two groups. The plastic surgery cohort had a higher rate of patients who were underweight (57.1% vs 14.3%, P < 0.01) and had positive preoperative wound cultures (28.6% vs 8.9%, P = 0.05), as well as a higher rate of postoperative antibiotic usage (78.6 vs 17.9%, P < 0.01). There was no difference in recorded postoperative outcomes. CONCLUSIONS: Spine surgeons requested paraspinous flap closure for patients with more complex disease, preoperative infections, history of chemotherapy, or if they were underweight. Patients with paraspinous flap coverage did not have increased postoperative complications despite their elevated risk profile. Our findings suggest that paraspinous muscle flaps should be considered in high-risk pediatric patients who undergo spine surgery.

Autoradiographic labelling of metabotropic glutamate type 2/3 receptors in the hemi-parkinsonian rat brain.

L-3,4-dihydroxyphenylalanine (L-DOPA) is the treatment of choice for Parkinson's disease (PD) motor symptoms, but its chronic use is hindered by complications such as dyskinesia. Pre-clinical studies discovered that activation of metabotropic glutamate type 2 and 3 (mGlu2/3) receptors alleviates L-DOPA-induced dyskinesia. To gain mechanistic insight into the anti-dyskinetic activity of mGlu2/3 activation, we performed autoradiographic binding with [3H]-LY-341,495 in brain sections from L-DOPA-treated 6-hydroxydopamine (6-OHDA)-lesioned rats that developed mild or severe dyskinesia, as well as L-DOPA-untreated 6-OHDA-lesioned and sham-lesioned animals. In the ipsilateral hemisphere, mildly dyskinetic 6-OHDA-lesioned rats showed a decrease in [3H]-LY-341,495 binding in the entopeduncular nucleus (EPN, 30 % vs sham-lesioned rats, P<0.05), globus pallidus (GP, 28 % vs sham-lesioned rats, P<0.05; 23 % vs L-DOPA-untreated 6-OHDA-lesioned rats, P<0.001), and primary motor cortex (49 % vs sham-lesioned rats, P<0.05; 45 % vs L-DOPA-untreated 6-OHDA-lesioned rats, P<0.001). Severely dyskinetic 6-OHDA-lesioned rats exhibited an increase in binding in the primary motor cortex (43 % vs mildly dyskinetic 6-OHDA-lesioned rats, P<0.05). In the contralateral hemisphere, mildly dyskinetic 6-OHDA-lesioned rats harboured a decrease in binding in the EPN (30 % vs sham-lesioned rats; 24 % vs L-DOPA-untreated 6-OHDA-lesioned rats, both P<0.05), GP (34 % vs sham-lesioned rats, P<0.05; 23 % vs L-DOPA-untreated 6-OHDA-lesioned rats, P<0.001), and primary motor cortex (50 % vs sham-lesioned rats; 44 % vs L-DOPA-untreated 6-OHDA-lesioned rats, both P<0.05). Severely dyskinetic 6-OHDA-lesioned rats presented a decrease in binding in the GP (30 % vs sham-lesioned rats; 19 % vs L-DOPA-untreated 6-OHDA-lesioned rats, both P<0.05). Abnormal involuntary movements scores of 6-OHDA-lesioned animals were positively correlated with [3H]-LY-341,495 binding in the ipsilateral striatum, ipsilateral EPN, ipsilateral primary motor cortex and contralateral primary motor cortex (all P<0.05). These results suggest that alterations in mGlu2/3 receptor levels may be part of an endogenous compensatory mechanism to alleviate dyskinesia.

Spontaneous coronary artery dissection: a focus on post-dissection care for the vascular medicine clinician.

Spontaneous coronary artery dissection (SCAD) is an uncommon condition which is increasingly recognized as a cause of significant morbidity. SCAD can cause acute coronary syndrome and myocardial infarction (MI), as well as sudden cardiac death. It presents similarly to atherosclerotic MI although typically in patients with few or no atherosclerotic risk factors, and particularly in women. As more patients are recognized to have this condition, there is a great need for clinician familiarity with diagnostic criteria, as well as with contemporary treatment approaches, and with appropriate patient-centered counseling, including genetic testing, exercise recommendations, and psychological care. The standard of care for patients with SCAD is rapidly evolving. This review therefore summarizes the diagnosis of SCAD, epidemiology, modern treatment, cardiac rehabilitation and preconception counseling, and the current approach to genetic testing, exercise recommendations, and psychological care, all of which are crucial to the vascular medicine specialist.

Posttraumatic Stress Disorder After Spontaneous Coronary Artery Dissection: A Report of the International Spontaneous Coronary Artery Dissection Registry.

BACKGROUND: Myocardial infarction secondary to spontaneous coronary artery dissection (SCAD) can be traumatic and potentially trigger posttraumatic stress disorder (PTSD). In a large, multicenter, registry-based cohort, we documented prevalence of lifetime and past-month SCAD-induced PTSD, as well as related treatment seeking, and examined a range of health-relevant correlates of SCAD-induced PTSD. METHODS AND RESULTS: Patients with SCAD were enrolled in the iSCAD (International SCAD) Registry. At baseline, site investigators completed medical report forms, and patients reported demographics, medical/SCAD history, psychosocial factors (including SCAD-induced PTSD symptoms), health behaviors, and health status via online questionnaires. Of 1156 registry patients, 859 patients (93.9% women; mean age, 52.3 years) completed questionnaires querying SCAD-induced PTSD. Nearly 35% (n=298) of patients met diagnostic criteria for probable SCAD-induced PTSD in their lifetime, and 6.4% (n=55) met criteria for probable past-month PTSD. Of 811 patients ever reporting any SCAD-induced PTSD symptoms, 34.8% indicated seeking treatment for this distress. However, 46.0% of the 298 patients with lifetime probable SCAD-induced PTSD diagnoses reported never receiving trauma-related treatment. Younger age at first SCAD, fewer years since SCAD, being single, unemployed status, more lifetime trauma, and history of anxiety were associated with greater past-month PTSD symptom severity in multivariable regression models. Greater past-month SCAD-induced PTSD symptoms were associated with greater past-week sleep disturbance and worse past-month disease-specific health status when adjusting for various risk factors. CONCLUSIONS: Given the high prevalence of SCAD-induced PTSD symptoms, efforts to support screening for these symptoms and connecting patients experiencing distress with empirically supported treatments are critical next steps.

[3H]-NFPS binding to the glycine transporter 1 in the hemi-parkinsonian rat brain.

L-3,4-dihydroxyphenylalanine (L-DOPA) is the main treatment for Parkinson's disease (PD) but with long term administration, motor complications such as dyskinesia are induced. Glycine transporter 1 (GlyT1) inhibition was shown to produce an anti-dyskinetic effect in parkinsonian rats and primates, coupled with an improvement in the anti-parkinsonian action of L-DOPA. The expression of GlyT1 in the brain in the dyskinetic state remains to be investigated. Here, we quantified the levels of GlyT1 across different brain regions using [3H]-NFPS in the presence of Org-25,935. Brain sections were chosen from sham-lesioned rats, L-DOPA-naïve 6-hydroxydopamine (6-OHDA)-lesioned rats and 6-OHDA-lesioned rats exhibiting mild or severe abnormal involuntary movements (AIMs). [3H]-NFPS binding decreased in the ipsilateral and contralateral thalamus, by 28% and 41%, in 6-OHDA-lesioned rats with severe AIMs compared to sham-lesioned animals (P < 0.01 and 0.001). [3H]-NFPS binding increased by 21% in the ipsilateral substantia nigra of 6-OHDA-lesioned rats with severe AIMs compared to 6-OHDA-lesioned rats with mild AIMs (P < 0.05). [3H]-NFPS binding was lower by 19% in the contralateral primary motor cortex and by 20% in the contralateral subthalamic nucleus of 6-OHDA-lesioned rats with mild AIMs animals compared to rats with severe AIMs (both P < 0.05). The severity of AIMs scores positively correlated with [3H]-NFPS binding in the ipsilateral substantia nigra (P < 0.05), ipsilateral entopeduncular nucleus (P < 0.05) and contralateral primary motor cortex (P < 0.05). These data provide an anatomical basis to explain the efficacy of GlyT1 inhibitors in dyskinesia in PD.

Statistical fragility of outcomes in acellular dermal matrix literature: A systematic review of randomized controlled trials.

BACKGROUND: Acellular dermal matrix (ADM) is commonly used in plastic and reconstructive surgery. With the abundance of randomized controlled trials (RCTs) reporting P-values for ADM outcomes, this study used the fragility index (FI), reverse fragility index (rFI), and fragility quotient (FQ) to evaluate the statistical stability of the outcomes in ADM RCTs. METHODS: PubMed, Embase, SCOPUS, Medline, and Cochrane databases were reviewed for ADM RCTs (2003-present) reporting a dichotomous, categorical outcome. FI and rFI (event reversals influencing outcome significance) and FQ (standardized fragility) were calculated and reported as median. Subgroup analysis was performed based on intervention types. RESULTS: Among the 127 studies screened, 56 RCTs with 579 outcomes were included. The median FI stood at 4 (3-5) and FQ was 0.04 (0.03-0.07). Only 101 outcomes were statistically significant with a median FI of 3 (1-6) and FQ of 0.04 (0.02-0.08). The nonsignificant outcomes had a median FI of 4 (3-5) and FQ of 0.04 (0.03-0.07). Notably, 26% of the outcomes had several patients lost to follow up equal to or surpassing the FI. Based on the intervention type, the median FIs showed minor fluctuations but remained low. CONCLUSIONS: Outcomes from ADM-related RCTs were statistically fragile. Slight outcome reversals or maintenance of patient follow-up can alter the significance of results. Therefore, future researchers are recommended to jointly report FI, FQ, and P-values to offer a comprehensive view of the robustness in ADM literature.

Faster discharge with lactated ringers than normal saline in first 72 h of acute pancreatitis: A multicenter randomized trial.

OBJECTIVES: Data driven strategies for acute pancreatitis (AP) in pediatrics are limited; adult data suggests lactated ringers (LR) compared to normal saline (NS) resulted in favorable outcomes, but has not been studied in pediatrics. Our objective was to evaluate the efficacy of LR during the first 48 h of an AP episode compared with NS. STUDY DESIGN: A multisite randomized controlled clinical trial, from 2015 to 2020 (Clinical Trials.gov NCT03242473). Patients were randomized to exclusively LR or NS for the first 48 h. Primary outcomes were serial C-reactive protein (CRP) values. Secondary outcomes included other lab values, time to feeds, length of stay (LOS), systemic inflammatory response syndrome (SIRS) development, and progression to severe AP (SAP). RESULTS: We studied 76 patients (38 LR, 38 NS). CRP at 24 and 48 h were not significantly different between LR or NS group. Additionally, there were no differences in trends of BUN, amylase, lipase, SIRS status, or SAP development between the LR and NS group at 24 and 48 h. A higher proportion of LR patients (32%, 12/38) were discharged before 48 h compared to NS (13%, 5/38). The LR group had a significantly higher rate of discharge within the first 72 h compared to the NS group (p = 0.02). CONCLUSION: The use of LR was associated with a faster rate of discharge during the intervention period and in the first 72 h, but no other differences compared to NS. This reduction in length of hospitalization has significant implications for patients and healthcare costs.

[Reform of early access program in France: Impact on workload in a pharmacy and risk identification]. / Réforme de l'accès dérogatoire : impact sur la gestion dans une PUI et identification des risques.

The reform of derogatory access authorisations (DAs) on 1st July 2021 has distorted the routine of the hospital pharmacists dealing with innovative medicines that are waiting for marketing authorization or approval. There are two distinct categories of DAs: Compassionate Access Authorisations (CAAs) are granted by the French National Agency for the Safety of Medicines (ANSM) while Early Access Authorisations (EAPs) are granted at the request of pharmaceutical companies by the French National Authority for Health (HAS). All AAPs and a majority of the AACs are supported by a Protocol for Therapeutic Use and Data Collection (PTU-DC). The aim of this study is to assess the impact of the reform on pharmacy process one year following its implementation, and to identify the risks related to the new circuits. The working group, composed of three pharmacists carried out an initial assessment of the effects first measured the impact of the reform on medicine processes in DAs. They performed a comparison of the changes in their management methods: 3 months prior to the reform (M0), and 3 (M3) and 12 months (M12) post-reform. Risks analysis was conducted using the Failure Modes, Effects and Criticality Analysis (FMEA) method. The analysis was limited to the process steps specific related to DAs drugs were analyzed. The critical severity of the risk situations identified was rated. A critical hierarchy matrix was used to establish priority actions. The priority actions to be taken were determined using the critical hierarchy matrix. Over the span of one year, the number of DAs in our establishment showed a 31.7% increase, from 41 at M0 to 54 at M12. At M0, the proportion of drugs needed inclusion via a drug-specific digital platform, specific to each drug, stood at 27% (11/41) of drugs at M0 while at M12, it rose to 52% (28/54). The percentage of PTU-DCs therefore increased by a factor of 1.7, rising from 29% (12/41) at M0 to 47% (21/45) at M3 and 60% (32/54) at M12. For orders, which are always nominative, approval depends on both the presence of the PTU-DC tracking sheet being present in 12% of PAAs, and the inclusion number in 26% of PAAs. The risk analysis shows 49 failure modes leading to risk situations. Among the failure modes, 36 have a consequence of acceptable or tolerable criticality under control, whilst 13 are deemed of unacceptable criticality. A suitable control method exists has been identifies for 5 of them. Finally, the ranking evaluation of criticalities has highlighted 4 situations which require immediate action as a priority: delivery times, obtaining completed tracking sheets and ordering procedures. The aim of the DAs reform is to simplify access to innovative medicines. However, the reform has significant and damaging repercussions on pharmaceutical activities. Corrective measures need to be taken in conjunction with all parties involved in the circuits including laboratories and service providers (CROs), authorities and healthcare professionals.

Rad Path in a Flash: Creation of the First AMSER Sponsored Digital Flashcard Deck and a Review of Digital Flashcard Use among? Medical Students.

RATIONALE AND OBJECTIVES: Digital flashcards are an increasingly popular study method for medical students today. The purpose of this study is to assess students' opinions on digital flashcards and to evaluate the need for radiology-focused digital flashcards. We created the first official Radiology-Pathology (Rad-Path) Correlation course digital flashcard deck sponsored by the Alliance of Medical Student Educators in Radiology (AMSER), and evaluated its effectiveness in increasing medical students' confidence levels of understanding Rad-Path concepts. MATERIALS AND METHODS: A 16-question survey was developed and publicly shared with medical students to assess the need for a high-quality radiology deck. In addition, students who trialed the AMSER Rad-Path Anki deck were assessed on their confidence of radiology pathology concepts prior to and after using these digital flashcards. RESULTS: 185 survey responses were received for the first survey about digital flashcard use. Overall, 87.6% of medical student respondents had used digital flashcards during medical school, and 33.5% had used digital flashcards to study radiology topics specifically. 67.6% of respondents stated they would use a digital flashcard deck if sponsored by an academic radiology society. Regarding the survey of the students who used the AMSER Rad-Path flashcards, 31 responses were received in the pre- and follow-up survey. Mean confidence in understanding the radiology pathology learning objectives increased when the Rad-Path Anki deck was utilized, and students rated the flashcards favorably. CONCLUSION: Students reported a high use of digital flashcards for studying topics in medical school. We identified a perceived need in students for a series of high-quality digital flashcards covering radiology topics. We created the first deck of AMSER Rad-Path flashcards which was well received by the medical students.

Association of Segment-Specific Pulse Wave Velocity With Vascular Calcification: The ARIC (Atherosclerosis Risk in Communities) Study.

BACKGROUND: Pulse wave velocity (PWV) is a noninvasive measure of arterial stiffness and predictor of cardiovascular disease. However, the association between PWV and vascular calcification across different vascular beds has not been fully investigated. This study aimed to quantify the association between PWV and multiterritory calcification and to explore whether PWV can identify individuals with vascular calcification beyond traditional risk factors. METHODS AND RESULTS: Among 1351 older adults (mean age, 79.2 years [SD, 4.1]) from the ARIC (Atherosclerosis Risk in Communities) study, we measured segment-specific PWVs: heart-carotid, heart-femoral, carotid-femoral, heart-ankle, brachial-ankle, and femoral-ankle. Dependent variables were high calcium score (≥75th percentile of Agatston score) across different vascular beds: coronary arteries, aortic valve ring, aortic valve, mitral valve, ascending aorta, and descending aorta. Quartiles of carotid-femoral, heart-femoral, heart-ankle, and brachial-ankle PWV were significantly associated with coronary artery calcium (eg, adjusted odds ratio [OR] for the highest versus lowest quartile of carotid-femoral PWV, 1.84 [95% CI, 1.24-2.74]). Overall, PWVs were most strongly associated with descending aorta calcification, with significant results for carotid-femoral, heart-femoral, heart-ankle, and brachial-ankle PWV (eg, adjusted OR for the highest versus lowest quartile of carotid-femoral PWV, 3.99 [95% CI, 2.61-6.17]). In contrast, femoral-ankle PWV was inversely associated with descending aorta calcification. Some PWVs improved the discrimination of coronary artery calcium and descending aorta calcification beyond traditional risk factors. CONCLUSIONS: The associations of PWV with vascular calcification varied substantially across segments, with descending aorta calcification most closely linked to PWVs. Our study suggests that some PWVs, especially carotid-femoral PWV, are helpful to identify individuals with coronary artery calcium and descending aorta calcification.

A single-cell atlas of IL-23 inhibition in cutaneous psoriasis distinguishes clinical response.

Psoriasis vulgaris and other chronic inflammatory diseases improve markedly with therapeutic blockade of interleukin-23 (IL-23) signaling, but the genetic mechanisms underlying clinical responses remain poorly understood. Using single-cell transcriptomics, we profiled immune cells isolated from lesional psoriatic skin before and during IL-23 blockade. In clinically responsive patients, a psoriatic transcriptional signature in skin-resident memory T cells was strongly attenuated. In contrast, poorly responsive patients were distinguished by persistent activation of IL-17-producing T (T17) cells, a mechanism distinct from alternative cytokine signaling or resistance isolated to epidermal keratinocytes. Even in IL-23 blockade-responsive patients, we detected a recurring set of recalcitrant, disease-specific transcriptional abnormalities. This irreversible immunological state may necessitate ongoing IL-23 inhibition. Spatial transcriptomic analyses also suggested that successful IL-23 blockade requires dampening of >90% of IL-17-induced response in lymphocyte-adjacent keratinocytes, an unexpectedly high threshold. Collectively, our data establish a patient-level paradigm for dissecting responses to immunomodulatory treatments.
