ABSTRACT

The main objective of this work is to develop a novel multi-scale analysis framework for coronavirus disease diagnosis from Chest X-Ray images. A scale-space representation is created by applying the numerical approximation algorithm that solves a new well-posed nonlinear anisotropic diffusion-based model. A 2D circular filter-based feature extraction is performed at each scale and the feature vectors determined at multiple scales are then combined into the final medical image descriptor. Next, a supervised binary classification process is performed on these final feature vectors, by using a training medical image set, its output representing the COVID-19 detection result. Some numerical simulations representing coronavirus detection tests are finally discussed in this paper.

ABSTRACT

Background: Medical research is critical to professional advancement, and mentoring is an important means of early research engagement in medical training. In contrast to international research collaborations, research mentoring programs are often locally limited. With the COVID- 19 pandemic causing drifts to virtual classes and conferences, virtual international medical research mentoring may be viable. We hereby describe our experience with a virtual, international mentorship group for cardiovascular research. Methods: Our virtual international research mentorship group has been running since 2015. The group focuses on risk stratification and outcomes research in cardiovascular medicine and epidemiology. Mentees from any country or region in all stages of medical careers are welcomed. Considering the increasing emphasis of contemporary research on multidisciplinary healthcare and translational research, our team also includes allied healthcare professionals or students, and graduates from natural sciences (Figure 1). With our members' diverse backgrounds, we firmly adhere to the principle that all members must be given equal opportunities and treatment, regardless of their age, gender, race, nationality, sexual orientation, family background, and institution of study or practice. We make use of virtual platforms and multi-level mentoring (both senior and peer mentoring), and emphasize active participation, early leadership, open culture, accessible research support, and a distributed research workflow (i.e. an accessible-distributed model). Results: Since establishment, our group has expanded to include 63 active members from 14 countries (Figure 2), leading a total of 109 peer-reviewed original studies and reviews published. We observed no significant difficulty in communication between team members, nor conflicts due to differences in nationality or ethnicity. Most studies involve cross-country and ethnicity collaborations, and inter-disciplinary and inter-regional knowledge exchanges are frequent. Multi-level mentoring ensured mentoring quality without compromising bonding and communication. Conclusion: An accessible-distributed model of virtual international medical research collaboration and multi-level mentoring is viable, efficient, and caters to the needs of contemporary healthcare. We hope that others will build similar models and improve medical research mentoring globally. (Figure Presented).

ABSTRACT

Background: Dupilumab has been recently approved for treatment in patients with severe AD in Portugal-until now there is no published data regarding Portuguese experience in Allergy centers. Method: Cross sectional clinical and laboratory assessment of 33 patients (pts) with moderate to severe AD treated with dupilumab (dupi) for at least 16 weeks (W): prospective evaluation of severity scores (SCORAD-Scoring Atopic Dermatitis, EASI-Eczema Area and Severity Index, P-VAS-Pruritus Visual Analogic Scale), report of adverse events up to 52 weeks of treatment. SCORAD and EASI were assessed in 23 pts at W52, P-VAS in 21 pts at W52. Results: Of the 33 pts, 18 were female (55%) with a mean age (SD, range) of 35.3 years (13.2, 15-60). In 16 pts the age of onset was before 2 years old, mean (SD) disease duration 28.1 years (12);94% patients had a diffuse pattern of skin lesions;97% of pts had allergic rhinitis, 82% asthma, 52% conjunctivitis and 30% food allergy. Median total IgE at baseline was of 6313 U/ml (P25-P75: 2842-12491) with a 76% reduction at W52 in 16 pts. Median eosinophil count at baseline was 520 eosinophils/mm3 (P25-P75: 270-740). Before starting dupi 29 pts had been treated with cyclosporine. At the beginning, 15 pts were under oral corticosteroids, 14 under oral systemic immunosuppressive drugs (all pts but two stopped both until W12 of dupi) and 5 switched from omalizumab. At baseline, median SCORAD and EASI were 69.3 and 24.2 points. At W16, W36 and W52, median SCORAD was 27.4, 22.3 and 21.5, and median EASI 5.3, 4.1 and 2.1. At W16, the EASI-50, EASI-75 and EASI-90 were achieved by 91%, 61% and 18% pts, and at W52, by 87%, 70% and 52% pts. The mean percentage of SCORAD reduction at W16 and W52 was 55% and 73%;and of EASI was 76% and 82%. At W16 and W52, an improvement of ≥4 points in P-VAS was achieved by 77% and 95% pts. There was a mean reduction of P-VAS at W2, W4, W16 and W52 of 2.6;3.6;4.7 and 6.3 points, respectively. Conjunctivitis was reported in 10 (30%) pts, two of them with keratoconjunctivitis and blepharitis, without needing to interrupt treatment;two pts also had facial erythema. One patient had COVID, and dupilumab scheme treatment was maintained. Conclusion: The majority of AD patients had a significant and consistent improvement in all the severity scores, after one year of treatment with dupilumab. No relevant adverse events were reported.

ABSTRACT

Gestational diabetes mellitus (GDM) is recognized as one of the most common medical complications of pregnancy that can lead to significant short-term and long-term risks for the mother and the fetus if not detected early and treated appropriately. Current evidence suggests that, with the use of appropriate screening programs for GDM, those women diagnosed and treated have reduced perinatal morbidity. It has been implied that, when screening for GDM, there should be uniformity in the testing used and in further management. This paper summarizes and compares current screening strategies proposed by international bodies and discusses application in the context of the COVID-19 pandemic.
