Abstract. Accurately mapping impervious-surface dynamics has great scientific
significance and application value for research on urban sustainable development, the assessment of anthropogenic carbon emissions and global ecological-environment modeling. In this study, a novel and automatic method of
combining the advantages of spectral-generalization and automatic-sample-extraction strategies was proposed, and then an accurate global 30 m impervious-surface dynamic dataset (GISD30) for 1985 to 2020 was produced using
time-series Landsat imagery on the Google Earth Engine cloud computing
platform. Firstly, the global training samples and corresponding reflectance
spectra were automatically derived from prior global 30 m land-cover
products after employing the multitemporal compositing method and relative
radiometric normalization. Then, spatiotemporal adaptive classification
models, trained with the migrated reflectance spectra of impervious surfaces
from 2020 and transferred pervious-surface samples in each epoch for every
5∘×5∘ geographical tile, were applied to map
the impervious surface in each period. Furthermore, a spatiotemporal-consistency correction method was presented to minimize the effects of
independent classification errors and improve the spatiotemporal consistency
of impervious-surface dynamics. Our global 30 m impervious-surface dynamic
model achieved an overall accuracy of 90.1 % and a kappa coefficient of
0.865 using 23 322 global time-series validation samples. Cross-comparisons
with five existing global 30 m impervious-surface products further indicated
that our GISD30 dynamic product achieved the best performance in capturing
the spatial distributions and spatiotemporal dynamics of impervious surfaces
in various impervious landscapes. The statistical results indicated that the
global impervious surface has doubled in the past 35 years, from
5.116×105 km2 in 1985 to 10.871×105 km2 in 2020, and Asia saw the largest increase in impervious surface area compared to other continents, with a total increase of 2.946×105 km2. Therefore, it was concluded that our global 30 m
impervious-surface dynamic dataset is an accurate and promising product and
could provide vital support in monitoring regional or global urbanization as
well as in related applications. The global 30 m impervious-surface dynamic
dataset from 1985 to 2020 generated in this paper is free to access at

Objective: Perturbation exercises conducted on mobile surfaces in the latter period of the rehabilitation increase the neuromuscular control. The purpose of the study was to investigate the effects of single session perturbation exercises’ on active joint position sense and on the electromyography activation of the trapezius muscle in patients who underwent arthroscopic rotator cuff repair in the previous 6 months.
Method: 12 individuals who underwent arthroscopic rotator cuff repair were included in the study as the study group (age: 54.83±3.5), and 13 individuals with in an asymptomatic shoulder joint were included as the control group (age: 49.07±4.5). All subjects were evaluated before and after single-session perturbation exercise. Active joint position sense at 90° shoulder flexion and abduction was assessed using a laser pointer-assisted angle reproduction test. The activation of the trapezius muscles during this test was recorded by the superficial electromyography tool. The pre-exercise and post-exercise values were analyzed using an in-group Wilcoxon signed-rank test. The Mann–Whitney U test was used for group comparisons.
Results: There was no difference between groups in the active angle reproduction test before and after the perturbation exercise (flexion p:0.124; abduction p:0.421). When electromyography activations after the exercise were compared, the activation of the operated upper trapezius (p:0.01) and the non-operated lower trapezius decreased (p:0.024). There was no correlation between the electromyography activation of the trapezius muscle and active joint position sense (flexion p:0.657; abduction p:0.662).

Published: April 2022

Background: Aspirin-exacerbated respiratory disease (AERD) is a chronic disease characterized by chronic rhinosinusitis, nasal polyposis, asthma, and intolerance to nonsteroidal anti-inflammatory drugs (NSAIDs). Aspirin challenge is considered the gold standard for diagnosing AERD. Many patients with AERD have reported clinical benefits when desensitized to aspirin and maintained on daily aspirin therapy. In this study, we have summarized aspirin challenges and aspirin desensitization in our division during the past ten years.
Methods: We reviewed aspirin challenges and desensitization procedures performed in the Allergy and Immunology Division at the Hamad Medical Corporation, Doha, Qatar, between 2010 and 2020 from our procedures log registry and reported the results of the procedures.
Results: The procedures were performed for patients with chronic rhinosinusitis, nasal polyposis, and bronchial asthma with a historical reaction to NSAIDs or those never exposed to NSAIDs. The challenge and desensitization procedure protocol is outlined in table.1. Of the 45 procedures performed, 36 (80%) patients reacted during aspirin desensitization; and their characteristics, historical reaction to NSAIDs, provoking dose, length of desensitization, and types of reactions were reviewed. Of the reactors, 32 (88%) patients completed aspirin desensitization successfully. The mean ( ± SD) age of patients was 46 ( ± 11.6) years, and 51% were women. The historical symptoms were asthma symptoms (56%) and naso-ocular (21%). The common (71%) reaction during the procedure was asthma symptoms, and 29% had naso-ocular symptoms. The provoking dose was 50–75 mg in most patients. The desensitization procedure was carried out over 2 days in most patients; however, 29% of the patients needed more than 2 days to complete the desensitization. None of the reactors needed emergency epinephrine use or hospital admission.
Conclusion: In our review, desensitization was successful in all the patients who reacted to aspirin, and it was the only therapeutic choice for patients with AERD before the era of biologics. The procedure was well tolerated in most patients. Aspirin challenge was positive in 80% of our patients with suspected AERD, and this has an important diagnostic value that may help in choosing the proper biologic, such as dupilumab, for these patients.
Myths, misconceptions, and hesitancy in people residing in Qatar toward mRNA COVID-19 vaccines: An experience exchange from Qatar University health center

Published: April 2022

The hesitancy in taking COVID-19 vaccines is a complex process influenced by several factors, including individual, social, and cultural. Health literacy and community awareness around mRNA COVID-19 vaccines are critical for successfully combating the pandemic. Healthcare professionals, including family physicians and nurses, can help increase community awareness and mitigate some misconceptions and hesitancy regarding mRNA COVID-19 vaccines in people's attitudes. Therefore, in this study, we aimed to explore how the interaction between an individual's social identities such as gender, ethnicity, culture, knowledge, and belief impact their hesitancy and attitudes toward mRNA COVID-19 vaccines. We aimed to describe our experience in dealing with people residing in Qatar from the perspective of healthcare practitioners from the Qatar University Health Center during the period when mRNA COVID-19 vaccines was introduced in a time frame of 6 months (April to October, 2021).
We identified several factors associated with the reluctance to receive mRNA COVID-19 vaccines once vaccination services were available, affordable, and accessible to everyone in Qatar (). Most individuals were hesitant and refused to take mRNA COVID-19 vaccines owing to the unjustified myths and fear about potential side effects of vaccines in general and unknown long-term effects of vaccination, especially among women who were uneducated. We believe we have been able to put forth a fair, unbiased, and balanced argument between an individual's right to take or refuse the vaccine and the overall benefits to the public and community health in terms of the overall community immunity when the vast majority of the population will be vaccinated. Our experience could assist in developing culturally sensitive and tailored community outreach programs to increase community awareness as it is the cornerstone on which public health can fight the irrational myths, fear, misconceptions, vaccine hesitancy, and improve vaccination coverages. Moreover, our shared experiences might be able to better prepare future launching of pandemic vaccination campaigns in order to minimize vaccine hesitancy.

Authors: Mohammed-Ali Ramzy , Jerobin Jayakumar , Khalil Sally , Sivaraman Siveen , Ramanjaneya Manjunath , Betahi Ilham , Badi Abou Samra Abdul , Al-Nesf Maryam 
Published: April 2022

Background: Chronic urticaria (CU) is a common and complex disorder that occurs without any identifiable provoking factor. The mechanisms underlying CU pathogenesis are still not fully understood. The autoimmune theory of IgG autoantibodies to IgE/high-affinity receptor of IgE on mast cells and mast cell activation and autoallergy (IgE-mediated disease) might contribute to CU pathogenesis. Extracellular vesicles (EVs) are membranous vesicles released from apoptotic or activated cells of different types. Elevated circulating levels of EVs in allergic diseases were associated with inflammation and disease progression. In this study, we aimed to investigate circulating EVs as potential biomarkers in patients with CU compared with that in healthy controls. Methods: We studied 15 patients with CU and 16 healthy controls. Circulatory EVs (plasma) were characterized by the presence of externalized phosphatidylserine (annexin V staining). Endothelial cells, platelets, T and B cells, macrophages, granulocytes, PECAM 2 1, and tissue factors were investigated. An unpaired t-test was used, and P < 0.05 was considered statistically significant. Results: We did not find significant differences in the total number of EVs in patients with CU. A significant decrease in the levels of T-cells (CD3) and endothelial cells (CD146) (P < 0.05) in these patients than in controls was found. No significant differences were observed between patients with CU and healthy controls in terms of platelets, macrophages, PECAM-1, B cells, and tissue factors. Conclusion: Endothelial cells have been shown to contribute to the pathogenesis of CU and are also targeted by mediators released by mast cells and other cellular infiltrates. We identified that circulatory endothelial and T-cell EVs might play an important role in CU pathogenesis. In addition, our study highlights the importance of EVs as future therapeutic targets to be investigated.

Published: April 2022

Background: Allergic rhinitis and asthma exacerbation are strongly linked to respiratory viral and bacterial infections. COVID-19 pandemic has raised concerns about the risk of infection and the severity of COVID-19 infection in patients with asthma and allergic rhinitis. However, increasing evidence suggests that atopic disease protects against severe COVID-19 illness owing to the underlying type 2 inflammatory process. Many studies have reported the impact of asthma on COVID-19 disease; however, data on allergic rhinitis are scarce. In this study, we aimed to investigate the severity and outcome of COVID-19 disease in adult patients with allergic rhinitis in Qatar during the first pandemic wave.
Methods: We conducted a retrospective chart review of adult patients with a confirmed diagnosis of asthma and/or allergic rhinitis who had a positive COVID-19 RT-PCR between February 01, 2020, and December 01, 2020. Parameters evaluated included the WHO classification of COVID-19 disease severity as mild, moderate, severe, and critical; COVID-19 disease outcome; and mortality. Patients with allergic rhinitis were defined as those with typical allergic rhinitis symptoms and positive skin prick test or specific IgE to perennial or seasonal inhaled allergens. Only data about patients with allergic rhinitis has been presented in this report.
Results: We screened 97 EMR Cerner records of patients who had the diagnosis code for allergic rhinitis. Nine patients met the inclusion criteria of allergic rhinitis diagnosis; the remaining either had no allergy testing or had negative allergy tests. Seven (77.7%) patients had mild COVID-19, whereas only one (11.1%) patient each had moderate and severe disease. The length of hospital stays for 6 patients ranged from 5–13 days, and the remaining 3 patients were quarantined at home. No reports of critical cases or death were identified. All the patients recovered from COVID-19 with a favorable outcome.
Conclusion: This preliminary data showed that most patients with allergic rhinitis had mild COVID-19 disease. Furthermore, all of them recovered well, similar to the available data from previous studies. A limitation of this study is the small population size.

Published: April 2022

Neste artigo tem-se como objetivo geral: refletir sobre os comprometimentos da saúde docente no contexto do trabalho remoto em tempos da pandemia da Covid-19. Utiliza-se como base de análise observações participantes em reuniões dos/as docentes do Curso de Pedagogia da Universidade Federal do Maranhão. Como instrumentos de investigação usou-se observação participante e pesquisa bibliográfica. Para análise dos dados, fez-se uso da interpretação e inferência dos dados. Concluiu-se que a pandemia da Covid-19 intensificou um quadro que expõe os docentes a um cenário de adoecimentos atravessado por sentimentos de medo, ansiedade, estresse e depressão. Adoecimentos que têm levado muitos docentes a afastamentos, assim como a quadros sérios de enfermidade, destituindo-os da possibilidade de orgulhar-se de seu fazer profissional. Assim, considera-se fundamental equilibrar a produção da pesquisa básica e aplicada em todos os setores da sociedade, em especial Saúde e Educação, campos da ciência fundamentais à qualidade de vida.

Exclusive study on operation of 31 bis of trips-with special reference to public health
Authors: Maheswari S. Uma , Balu N. 
Published: April 2022

World wars brought economic depression resulting in the need to regulate the trade relationship among the international community. Such a need to regulate trade relationships among world states compelled them to sign the General Agreement on Tariffs and Trade (GATT) agreement. The initial stages of GATT did not have provisions to protect Intellectual Property Rights. There were international conventions to address the issues concerning Trade aspects of intellectual property. The international conventions were like the Paris convention for protecting an invention, Berne for Copyright, Madrid for Trademarks etc… Several rounds of GATT gave birth to the World Trade Organization in 1995. The World Trade Organization (WTO) planned to bring unification of Intellectual Property Laws and enacted a new multilateral agreement on Trade-related aspects of Intellectual Property Rights (TRIPS). TRIPS are multifaceted agreements where many aspects of IPR are discussed. Article 31 bis of TRIPs agreement concerning public health will be critically analysed in this paper. Article 31 Bis was the result of the Doha declaration that deeply discussed the issue of Article 31 F and its gap in serving the countries that lack the manufacturing capacity to address their issues of accessibility and affordability to pharmaceutical products.
