Clinical applications of deep learning in neuroinflammatory diseases: A scoping review.

BACKGROUND: Deep learning (DL) is an artificial intelligence technology that has aroused much excitement for predictive medicine due to its ability to process raw data modalities such as images, text, and time series of signals. OBJECTIVES: Here, we intend to give the clinical reader elements to understand this technology, taking neuroinflammatory diseases as an illustrative use case of clinical translation efforts. We reviewed the scope of this rapidly evolving field to get quantitative insights about which clinical applications concentrate the efforts and which data modalities are most commonly used. METHODS: We queried the PubMed database for articles reporting DL algorithms for clinical applications in neuroinflammatory diseases and the radiology.healthairegister.com website for commercial algorithms. RESULTS: The review included 148 articles published between 2018 and 2024 and five commercial algorithms. The clinical applications could be grouped as computer-aided diagnosis, individual prognosis, functional assessment, the segmentation of radiological structures, and the optimization of data acquisition. Our review highlighted important discrepancies in efforts. The segmentation of radiological structures and computer-aided diagnosis currently concentrate most efforts with an overrepresentation of imaging. Various model architectures have addressed different applications, relatively low volume of data, and diverse data modalities. We report the high-level technical characteristics of the algorithms and synthesize narratively the clinical applications. Predictive performances and some common a priori on this topic are finally discussed. CONCLUSION: The currently reported efforts position DL as an information processing technology, enhancing existing modalities of paraclinical investigations and bringing perspectives to make innovative ones actionable for healthcare.

Geographic Distribution of Facial Plastic and Reconstructive Surgeons.

Background: Distribution of the general otolaryngology workforce has been described, but not specifically for the facial plastic and reconstructive surgeon (FPRS) workforce. Objective: To describe the distribution of FPRS within the United States. Methods: The 2022 American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS) registry was used to identify active FPRSs. Member addresses were converted into coordinates and overlayed onto a geographic representation of 2020 census data within ArcGIS software. A centroid model of U.S. counties was constructed to determine the average distances residents were from the nearest FPRS. Results: In total, 1312 AAFPRS active members practiced in 373 counties. Thirty-three percent of all residents (115 million) resided in counties without an FPRS and 15.3% of FPRSs practiced in New York City or the Greater Los Angeles Area, which accounted for 8% of the total U.S. population. The mean and median distances a resident in a county without an FPRS was from the nearest FPRS are 63 and 49 miles (101 and 79 kilometers), respectively. Conclusions: Metropolitan areas have greater concentrations of FPRSs than the national average and the distances U.S. residents are from FPRS services are quantifiable.

Hybrid quantum systems with high-T[Formula: see text] superconducting resonators.

Superconducting microwave resonators are crucial elements of microwave circuits, offering a wide range of potential applications in modern science and technology. While conventional low-T[Formula: see text] superconductors are mainly employed, high-T[Formula: see text] cuprates could offer enhanced temperature and magnetic field operating ranges. Here, we report the realization of [Formula: see text] superconducting coplanar waveguide resonators, and demonstrate a continuous evolution from a lossy undercoupled regime, to a lossless overcoupled regime by adjusting the device geometry, in good agreement with circuit model theory. A high-quality factor resonator was then used to perform electron spin resonance measurements on a molecular spin ensemble across a temperature range spanning two decades. We observe spin-cavity hybridization indicating coherent coupling between the microwave field and the spins in a highly cooperative regime. The temperature dependence of the Rabi splitting and the spin relaxation time point toward an antiferromagnetic coupling of the spins below 2 K. Our findings indicate that high-Tc superconducting resonators hold great promise for the development of functional circuits. Additionally, they suggest novel approaches for achieving hybrid quantum systems based on high-T[Formula: see text] superconductors and for conducting electron spin resonance measurements over a wide range of magnetic fields and temperatures.

SAMCEP Society consensus on the treatment of upper facial lines with botulinum neurotoxin type A: A tailored approach.

BACKGROUND: The safety and efficacy of botulinum neurotoxin type A (BoNTA) treatments are well established, but injection techniques, target muscles, and toxin doses continue to evolve, with each refinement producing improvements in treatment outcomes. The recommendations in this consensus move away from standard templates and illustrate how to tailor treatments to individual patterns and strengths of muscle activity, and patient preferences. METHODS: Seventeen experts in the fields of plastic surgery, dermatology, ophthalmology, otorhinolaryngology, and neurology convened in 2022 to develop consensus-based recommendations for the use of botulinum toxin A for the treatment of horizontal forehead lines, glabellar frown lines, and crow's feet lines that reflect current clinical practice. The focus was on how to tailor injections to individual patients to optimize treatment outcomes. RESULTS: For each upper face indication, consensus members describe how to perform a dynamic assessment to optimize the dose and injection technique for each patient. A tailored treatment protocol is presented for commonly observed patterns of dynamic lines. Units of Inco are defined and the precise location of injection points, illustrated with the use of anatomical images. CONCLUSION: This consensus provides up-to-date recommendations on the tailored treatment of upper facial lines based on the latest research and collective clinical experience of the expert injectors. Optimal outcomes require thorough patient evaluation, both at rest and during animation, using both visual and tactile cues; detailed understanding of facial muscular anatomy and how opposing muscles interact; and use of a BoNTA with high precision to target identified zones of excess muscle activity.

[Autoimmune and inflammatory pathologies associated with systemic scleroderma: Clinical, serological and prognostic profiles. Bi-centric retrospective series in the PACA region]. / Pathologies auto-immunes et inflammatoires associées à la sclérodermie systémique : profils cliniques, sérologiques et pronostiques. Série rétrospective bi-centrique en région PACA.

INTRODUCTION: Systemic sclerosis (SSc) is a rare auto-immune disease, affecting principally women between 40 and 60 years old. It is caracterised by a cutaneous and visceral fibrosis, an alteration of the microvascular network and the presence of autoantibodies. SSc can be associated with another connectivite tissue disease or to other autoimmune diseases, thus defining the overlap syndrome. The goal of our study is to describe these overlap syndromes. METHODS: We have analysed the data of a retrospective and bicentrique cohort, from the internal medicine unit of Hôpital Nord in Marseille and from the internal medicine unit of the Hôpital Sainte-Anne in Toulon, of patients followed for a SSc between January 1st, 2019 and December 1st, 2021. We have collected clinical, imunological features, associated auto-immune and inflammatory diseases with its morbidity and mortality. RESULTS: The cohort included 151 patients including 134 limited cutaneous SSc. Fifty-two (34.4%) patients presented at least one associated auto-immune or inflammatory disease. The association of two connectivite tissue diseases including SSc was found in 24 patients (15.9%), a third with Sjögren's syndrome and a third with autoimmune myositis. The principal associated disease to SSc was the autoimmune thyroiditis found in 17 patients (11.3%). The occurrence of complications (hospitalization, long-term oxygene therapy, death) was not significantly different depending on the existence or not of an overlap syndrom. CONCLUSION: SSc is often associated with other autoimmune diseases. This interrelation between associated pathologies and SSc, modifying sometimes the evolution of SSc, enhances the need of a personalized follow-up.

Impact of Moderate Aortic Stenosis in Patients With Heart Failure With Reduced Ejection Fraction.

BACKGROUND: Afterload from moderate aortic stenosis (AS) may contribute to adverse outcomes in patients with heart failure with reduced ejection fraction (HFrEF). OBJECTIVES: The authors evaluated clinical outcomes in patients with HFrEF and moderate AS relative to those without AS and with severe AS. METHODS: Patients with HFrEF, defined by left ventricular ejection fraction (LVEF) <50% and no, moderate, or severe AS were retrospectively identified. The primary endpoint, defined as a composite of all-cause mortality and heart failure (HF) hospitalization, was compared across groups and within a propensity score-matched cohort. RESULTS: We included 9,133 patients with HFrEF, of whom 374 and 362 had moderate and severe AS, respectively. Over a median follow-up time of 3.1 years, the primary outcome occurred in 62.7% of patients with moderate AS vs 45.9% with no AS (P < 0.0001); rates were similar with severe and moderate AS (62.0% vs 62.7%; P = 0.68). Patients with severe AS had a lower incidence of HF hospitalization (36.2% vs 43.6%; P < 0.05) and were more likely to undergo AVR within the follow-up period. Within a propensity score-matched cohort, moderate AS was associated with an increased risk of HF hospitalization and mortality (HR: 1.24; 95% CI: 1.04-1.49; P = 0.01) and fewer days alive outside of the hospital (P < 0.0001). Aortic valve replacement (AVR) was associated with improved survival (HR: 0.60; CI: 0.36-0.99; P < 0.05). CONCLUSIONS: In patients with HFrEF, moderate AS is associated with increased rates of HF hospitalization and mortality. Further investigation is warranted to determine whether AVR in this population improves clinical outcomes.

Linked fate among underrepresented groups: Investigating the relationships between Black college students' perceptions of institutional diversity climate and mental health.

Objective: Negative perceptions of institutional racial climate relate to worse mental health outcomes for Black college students. Yet, few scholars have considered how Black students' perceptions of the institutional climate for other underrepresented groups may impact mental health. Participants and Methods: We drew on a national sample of Black college students across 15 institutions (n = 1188) to examine the effects of institutional diversity climate on students' anxiety, depression, and positive mental health. Results: Black students who perceived the campus as more welcoming to first-generation reported higher positive mental health. Black students who perceived the campus as more welcoming to racial minorities, lesbian, gay, bisexual (LGB), and low socioeconomic status (SES) students reported lower levels of depression and anxiety. Conclusions: Black students' perceptions of the institutional diversity climate for other groups influences their mental health outcomes, and underscores the need for more research on individual-level differences in students' mental health processes.

Effects of ACE inhibitors and angiotensin receptor blockers: protocol for a UK cohort study using routinely collected electronic health records with validation against the ONTARGET trial.

INTRODUCTION: Cardiovascular disease is a leading cause of death globally, responsible for nearly 18 million deaths worldwide in 2017. Medications to reduce the risk of cardiovascular events are prescribed based on evidence from clinical trials which explore treatment effects in an indicated sample of the general population. However, these results may not be fully generalisable because of trial eligibility criteria that generally restrict to younger patients with fewer comorbidities. Therefore, evidence of effectiveness of medications for groups underrepresented in clinical trials such as those aged ≥75 years, from ethnic minority backgrounds or with low kidney function may be limited.Using individual anonymised data from the Ongoing Telmisartan Alone and the Ramipril Global Endpoint Trial (ONTARGET) trial, in collaboration with the original trial investigators, we aim to investigate clinical trial replicability within a real-world setting in the area of cardiovascular disease. If the original trial results are replicable, we will estimate treatment effects and risk in groups underrepresented and excluded from the original clinical trial. METHODS AND ANALYSIS: We will develop a cohort analogous to the ONTARGET trial within the Clinical Practice Research Datalink between 1 January 2001 and 31 July 2019 using the trial eligibility criteria and propensity score matching. The primary outcome is a composite of cardiovascular death, non-fatal myocardial infarction, non-fatal stroke and hospitalisation for congestive heart failure. If results from the cohort study fall within pre-specified limits, we will expand the cohort to include under represented and excluded groups. ETHICS AND DISSEMINATION: Ethical approval has been granted by the London School of Hygiene & Tropical Medicine Ethics Committee (Ref: 22658). The study has been approved by the Independent Scientific Advisory Committee of the UK Medicines and Healthcare Products Regulatory Agency (protocol no. 20_012). Access to the individual patient data from the ONTARGET trial was obtained by the trial investigators. Findings will be submitted to peer-reviewed journals and presented at conferences.

[Diagnostic issues of Whipple's disease during chronic inflammatory rheumatism: About three cases]. / Difficultés diagnostiques de la maladie de Whipple au cours des rhumatismes inflammatoires chroniques : trois observations.

INTRODUCTION: Whipple's disease (WD) can mimic chronic inflammatory rheumatism leading to incorrect prescription of tumor necrosis factor inhibitors (TNFI). Several complicated cases of WD have been reported during TNFI treatment which is strongly suspected to modify the host-pathogen relationship. Tropheryma whipplei asymptomatic carriage is high in the general population, making the diagnosis of WD more difficult face to unexplained arthritis. OBSERVATIONS: We report three observations that illustrate situations for which the detection of T. whipplei might be valuable to investigate the differential diagnosis of inflammatory rheumatism. CONCLUSION: The decision to check for T. whipplei infection should rely on individual clinical assessment. It should be considered in the absence of clinical response or in case of worsening of an inflammatory rheumatism under TNFI treatment, especially in front of atypical features. A systematic screening for T. whipplei before anti-TNF treatment seems unjustified since asymptomatic carriers are frequent.

[Perceptions of family doctors, pulmonologists and allergists on the approach to patients with chronic cough. Results of an anonymous survey]. / Percepciones de médicos de familia, neumólogos y alergólogos sobre el abordaje de los pacientes con tos crónica. Resultados de una encuesta anónima.

OBJECTIVE: To understand the perception of family doctors, pulmonologists and allergists about the current approach to chronic cough and its impact on patients' quality of life. MATERIAL AND METHODS: Cross-sectional and anonymous survey disseminated through the scientific societies SEAIC, SEMERGEN, semFYC, SEMG and SEPAR. The participants were 620 family doctors, 92 pulmonologists and 62 allergists. A descriptive analysis of the answers was conducted. Response percentages, medians and interquartile intervals were presented. The differences in the percentages between specialties were evaluated with the chi-square. RESULTS: Only half of the respondents chose a duration greater than 8 weeks as a criterion for diagnosing chronic cough, and less than half considered refractory/unexplained chronic cough a disease in itself. Family doctors perceived that chronic cough had less impact on patients than did pulmonologists or allergists. After a diagnosis of refractory/unexplained chronic cough, all 3specialties considered the most common approach to be to initiate treatment and to do the follow-up of the patient themselves. Most stated that they had no protocols for managing chronic cough, and more than 90% considered these to be necessary. CONCLUSIONS: The management of patients with chronic cough by family doctors, pulmonologists or allergists seems to be heterogeneous. There is a need for protocols that standardise diagnosis, referral and treatment criteria to optimise patients' management and reduce the impact of chronic cough.

Compliance with the clinical guidelines for managing asthma by primary care physicians: An ambispective observational study.

OBJECTIVE: To assess the degree of compliance with the recommendations of the 2009 and 2015 versions of the Spanish guidelines for managing asthma (Guía Española para el Manejo del Asma [GEMA]) and the effect of this compliance on controlling the disease. MATERIAL AND METHODS: We conducted an observational ambispective study between September 2015 and April 2016 in which 314 primary care physicians and 2864 patients participated. RESULTS: Using retrospective data, we found that 81 of the 314 physicians (25.8%; 95% CI 21.3-30.9) stated that they complied with the GEMA2009 recommendations. At the start of the study, 88 of the 314 physicians (28.0%; 95% CI 23.4-33.2) complied with the GEMA2015 recommendations. Poorly controlled asthma (OR, 0.19; 95% CI 0.13-0.28) and persistent severe asthma at the start of the study (OR, 0.20; 95% CI 0.12-0.34) were negatively associated with having well-controlled asthma by the end of the follow-up. In contrast, compliance with the GEMA2015 recommendations was positively associated with a greater likelihood that the patient would have well-controlled asthma by the end of the follow-up (OR, 1.70; 95% CI 1.40-2.06). CONCLUSIONS: Low compliance with the clinical guidelines for managing asthma is a common problem among primary care physicians. Compliance with these guidelines is associated with a better asthma control. Actions need to be taken to improve primary care physician compliance with the asthma management guidelines.

Eosinophilic pericardial effusion in a cat with complex systemic disease and associated peripheral eosinophilia.

An 11-year-old domestic shorthair cat was referred for investigation of dry cough of 1-week duration and cardiomegaly. Echocardiography revealed pericardial effusion, and eosinophils were identified as the predominant cell type in fluid collected by pericardiocentesis. Thoracic computed tomography imaging and bronchoscopy were supportive of mild lower airway disease, while bronchoalveolar lavage confirmed eosinophilic inflammation and concurrent Mycoplasma felis infection. A few months after the initial presentation, there was clinical deterioration, and further investigation suggested intestinal lymphoma. It was hypothesized that pericardial effusion and lower airway inflammation were an early manifestation of hypereosinophilic syndrome, possibly as a paraneoplastic consequence of lymphoma.

BrdU Positive Cells Induced in a Genetic Mouse Model of Glaucoma.

Previous studies have shown that eye drop application of the selective α7 nicotinic acetylcholine receptor agonist, PNU-282987, induces neurogenesis of RGCs in adult wild-type rodents. This study was designed to test the hypothesis that PNU-282987 reverses the loss of RGCs associated with glaucoma. A DBA/2J mouse model that auto-induces a glaucoma-like condition in adulthood was used for these studies. Short-term effects using PNU-282987 and BrdU eye drop treatments were examined, as well as the effects of early treatment and the effects in a chronic early treatment group in DBA/2J mice aged 3, 6 and 10 months. With and without treatment, retinas were removed, fixed, immunostained and RGC counts were assessed. IOP measurements were obtained weekly using a Tonolab tonometer. Results showed an average typical loss of BrdU positive RGCs by 29% by 10 months of age in this DBA/2J colony corresponding with a significant increase in IOP. However, the two-week short term application of PNU-282987 and BrdU induced a significant 21% increase in RGCs for DBA/2J mice at all ages. Chronic early PNU-282987 treatment produced a similarly significant increase in RGCs, while acute early treatment had no effect on RGC numbers. IOP measurements were not affected with PNU-282987 treatment. These studies demonstrated that 2-week treatment with PNU-282987, as well as chronic long-term treatment, induced a significant increase in the number of RGCs in the DBA/2J retina, counteracting the effects of the DBA/2J genetic glaucoma-like condition. These results suggest a potential future treatment of degenerative retinal diseases with PNU-282987.

Seguimiento de las guías españolas para el manejo del asma por el médico de atención primaria: un estudio observacional ambispectivo / Compliance with the clinical guidelines for managing asthma by primary care physicians: An ambispective observational study

Objetivo Evaluar el grado de seguimiento de las recomendaciones de las versiones de la Guía española para el manejo del asma (GEMA 2009 y 2015) y su repercusión en el control de la enfermedad. Material y métodos Estudio observacional y ambispectivo realizado entre septiembre del 2015 y abril del 2016, en el que participaron 314 médicos de atención primaria y 2.864 pacientes. Resultados Utilizando datos retrospectivos, 81 de los 314 médicos (25,8% [IC del 95%, 21,3 a 30,9]) comunicaron seguir las recomendaciones de la GEMA 2009. Al inicio del estudio, 88 de los 314 médicos (28,0% [IC del 95%, 23,4 a 33,2]) seguían las recomendaciones de la GEMA 2015. El tener un asma mal controlada (OR 0,19, IC del 95%, 0,13 a 0,28) y presentar un asma persistente grave al inicio del estudio (OR 0,20, IC del 95%, 0,12 a 0,34) se asociaron negativamente con tener un asma bien controlada al final del seguimiento. Por el contrario, el seguimiento de las recomendaciones de la GEMA 2015 se asoció de manera positiva con una mayor posibilidad de que el paciente tuviera un asma bien controlada al final del periodo de seguimiento (OR 1,70, IC del 95%, 1,40 a 2,06). Conclusiones El escaso seguimiento de las guías clínicas para el manejo del asma constituye un problema común entre los médicos de atención primaria. Un seguimiento de estas guías se asocia con un control mejor del asma. Existe la necesidad de actuaciones que puedan mejorar el seguimiento por parte de los médicos de atención primaria de las guías para el manejo del asma (AU)

Endometrial Sarcoma Metastasis to the Pterygopalatine Fossa: A Case Report and Review of the Literature.

Metastatic skull base malignancies infrequently occur but, when present, typically arise from breast malignancies. Pterygopalatine fossa (PPF) metastasis of any malignancy is further seldom reported, and metastasis of gynecologic malignancies to the PPF has not been previously described in the literature. We present a single case of a 42-year-old female with the first likely case of high-grade endometrial sarcoma metastatic to the PPF. The patient presented with facial pain and numbness in the V2 distribution presented for evaluation. History was significant for several months of dysmenorrhea and metrorrhagia. Computed tomography, magnetic resonance imaging, and positron emission tomography imaging revealed a PPF mass with local extension and bony metastases. Endoscopic biopsy was performed, and final pathology was most consistent with metastatic high-grade endometrial stromal sarcoma. This is the first reported case of likely metastatic endometrial sarcoma to the PPF. This case report highlights the possibility of rare distant metastasis of gynecologic malignancy to this area of the skull base.

Assessment of physical functioning in patients with chronic obstructive pulmonary disease (COPD) requiring long-acting dual bronchodilation in routine clinical practice.

OBJECTIVE: We aim to determine the effect of a fixed-dose combination (FDC) of tiotropium/olodaterol on Physical activity (PA) in patients with chronic obstructive pulmonary disease (COPD) in a real world setting. METHODS: COPD patients were prospectively enrolled to evaluate the effect of a FDC of tiotropium/olodaterol inhaler therapy via the Respimat® Soft Mist™ inhaler (SMI) on the physical functioning scale (PF-10), and the general condition of the patient as assessed by the physician (Physician's Global Evaluation, PGE), and the patient's satisfaction after 6 weeks of treatment. The primary end-point was the percentage of patients with therapeutic success at 6th week follow-up, defined as a ≥10-points increase in the standardised PF-10 score from baseline. RESULTS: A total of 257 patients from 57 sites were enrolled, and 234 completed the follow up. After 6 weeks of treatment, 155 out of 234 patients (66.2%) showed therapeutic success in the physical functioning score, coupled with significant improvement in PGE score: 78 (33.3%) patients with good/excellent PGE score at baseline, increasing to 172 (73.5%) at 6th week (p<0.0001). The patient's satisfaction was excellent: 77.2% reporting to be satisfied/very satisfied with the treatment, 79.9% with inhaling and 79.0% with the handling of SMI device. 1.6% of patients reported an investigator-defined drug-related adverse event. CONCLUSION: Treatment of COPD patients with a FDC of tiotropium/olodaterol SMI for 6 weeks resulted in significant improvements in the patients' condition as assessed by patients and physicians, with no new safety findings.
