Published: September 2020

Background

Impaired quality of life (QOL) is common in coronary heart disease and is the major indications for coronary artery bypass graft (CABG) operations. This study aims to compare the QOL of patients with coronary heart disease before and after CABG surgery.

Results

A translated Arabic version of the Mac-New health-related QOL questionnaire was used to evaluate QOL improvement in 446 patients who benefited from elective CABG at Nasser Institute for Research and Treatment. There was a statistically significant improvement in physical, emotional, social, and global domains of QOL, as evaluated 3 and 6 months after surgery. Follow-up was 90.4% complete. At 3 months, multiple linear regression has shown that male patients (β= 0.48,p≤ 0.001) and rural residence (β= 0.39,p≤ 0.001) were significant independent predictors of improvement in physical QOL domain. While hypercholesterolemia (β= −0.20, −0.49, −0.37, −0.46,p≤ 0.001), hypertension (β= −0.29, −0.39,p≤ 0.001,β= −0.35, −β= 0.35,p= 0.001), and smoking (β = −0.79,p≤ 0.001,β= −0.33,p= 0.04,β= −0.69,p≤ 0.001,β= −0.47,p= 0.005) were significant predictors of worsening in physical, emotional, social, and global domains, respectively. At 6 months, low preoperative ejection fraction (EF) ≤ 40% was the strongest predictor of improvement (β= 0.54, 0.49, 0.44, and 0.52,p≤ 0.001) in physical, emotional, social, and global domains of QOL, respectively. But, peripheral vascular disease (PVD) (β = −0.53,p= 0.05,β= −0.81,p= 0.005,β= −0.62,p= 0.03,β= −0.76,p= 0.008) and smoking (β= −0.53,p= 0.001,β= −0.42,p= 0.01,β= −0.42,p= 0.01,β= −0.41,p= 0.02) were significant predictors of worsening in physical, emotional, social, and global domains of QOL, respectively.

Conclusions

CABG surgery improved in all domains of QOL. Further studies are required to evaluate changes in QOL at longer period intervals.

Authors: Mortada Mohamed A. , Zidan Haidy E. , Abdelsalam Noha A. , Eltoukhy Mirvat A.
Published: September 2020

Background

Impaired deoxyribonucleic acid (DNA) repair may induce an autoimmune response in susceptible individuals. The association between DNA repair gene XRCC1 Arg399Gln gene polymorphism and susceptibility of systemic lupus erythematosus (SLE) is controversial. This study aimed to detect the association of XRCC1 Arg399Gln gene polymorphism with SLE and its clinical manifestations in the Egyptian population.

Results

A significant association was found between weight loss and genotype GG (P = 0.048); however, genotype AG was significantly associated with high serum creatinine and low C3 level (P = 0.039, P = 0.009, respectively). On the other hand, there was no significant difference between patients and controls regarding genotype and allele frequency.

Conclusions

An association was found between weight loss, high serum creatinine, and low C3 level and genotypes of XRCC1 Arg 399 Gln gene polymorphism.

Inter-compound and Intra-compound Global Sensitivity Analysis of a Physiological Model for Pulmonary Absorption of Inhaled Compounds
Authors: Melillo Nicola , Grandoni Silvia , Cesari Nicola , Brogin Giandomenico , Puccini Paola , Magni Paolo
Published: August 2020

In recent years, global sensitivity analysis (GSA) has gained interest in physiologically based pharmacokinetics (PBPK) modelling and simulation from pharmaceutical industry, regulatory authorities, and academia. With the case study of an in-house PBPK model for inhaled compounds in rats, the aim of this work is to show how GSA can contribute in PBPK model development and daily use. We identified two types of GSA that differ in the aims and, thus, in the parameter variability: inter-compound and intra-compound GSA. The inter-compound GSA aims to understand which are the parameters that mostly influence the variability of the metrics of interest in the whole space of the drugs’ properties, and thus, it is useful during the model development. On the other hand, the intra-compound GSA aims to highlight how much the uncertainty associated with the parameters of a given drug impacts the uncertainty in the model prediction and so, it is useful during routine PBPK use. In this work, inter-compound GSA highlighted that dissolution- and formulation-related parameters were mostly important for the prediction of the fraction absorbed, while the permeability is the most important parameter for lung AUC and MRT. Intra-compound GSA highlighted that, for all the considered compounds, the permeability was one of the most important parameters for lung AUC, MRT and plasma MRT, while the extraction ratio and the dose for the plasma AUC. GSA is a crucial instrument for the quality assessment of model-based inference; for this reason, we suggest its use during both PBPK model development and use.
Self-Fulfilling Debt Dilution: Maturity and Multiplicity in Debt Models
Authors: Aguiar Mark , Amador Manuel
Published: September 2020

We establish that creditor beliefs regarding future borrowing can be self-fulfilling, leading to multiple equilibria with markedly different debt accumulation patterns. We characterize such indeterminacy in the Eaton-Gersovitz sovereign debt model augmented with long maturity bonds. Two necessary conditions for the multiplicity are (i) the government is more impatient than foreign creditors, and (ii) there are deadweight losses from default. The multiplicity is dynamic and stems from the self-fulfilling beliefs of how future creditors will price bonds; long maturity bonds are therefore a crucial component of the multiplicity. We introduce a third party with deep pockets to discuss the policy implications of this source of multiplicity and identify the potentially perverse consequences of traditional “lender of last resort” policies.

Role of a regulatory and governance framework in human biological materials and data sharing in National Biobanks: Case studies from Biobank Integrating Platform, Taiwan and the National Biorepository, Uganda
Authors: Nansumba Hellen , Ssewanyana Isaac , Tai Micheal , Wassenaar Douglas
Published: September 2020

Background: In the last decade, Low- and Middle-Income Countries (LMICs) have set up Biobanks to collect human biological materials and associated data for genomic research and public health purposes. Biobanking gives rise to ethical challenges, such as informed consent, benefit sharing, confidentiality, ownership, commercialization and public participation which are harder to navigate in LMIC settings due to disparities in research infrastructure and capacity.  This paper summarizes presentations on Biobank related case studies from two countries, with a focus on challenges in the regulatory and governance framework and suggestions on how to mitigate them.  

Methods: Two case studies of Biobanks from LMICs have been used. The case studies were presented at the 2018 Global Forum on Bioethics in Research (GFBR) meeting on the “Ethics of data sharing and Biobanking in health research”.

Results: The case studies show that an integrated, well-regulated platform for human biological materials and data ensures good quality of human biological materials, saves resources and promotes mutual collaboration of work among researchers. National regulatory bodies are required to generate Biobanking guidelines and policies to facilitate guidance to the rapidly changing landscape of science.

Discussion: In general, LMICs have weaker research regulatory infrastructure and governance mechanisms for Biobanks than high-income countries. This has increased the fear of exploitation i.e. unfair distribution of risks and benefits. Establishment of Biobanks and producing effective scientific outcomes based on the Biobanking resources is difficult without a proper legislative, regulatory and governance framework.

Conclusion: These two case studies from different LMICs settings show that although in both settings there is strong awareness of the scientific and population health value of Biobanks and strong commitment to their establishment, regulatory and ethical guidance show gaps that need to be addressed.

Authors: Sarayloo Fatemeh , Crainic Teodor Gabriel , Rei Walter
Published: September 2020

This paper proposes a solution approach for the multicommodity capacitated fixed-charge network design problem with uncertain demand modeled as a two-stage stochastic program. The proposed learning-based matheuristic combines heuristic search techniques with mathematical programming. It provides a systematic approach to identifying structures of good-quality solutions by gradually considering scenarios and their influences on design decisions. Extensive computational experiments illustrate the efficiency of the proposed matheuristic in obtaining high-quality solutions with limited computational efforts.

Influence of task-oriented circuit training on upper limb function among rural community-dwelling survivors of stroke
Authors: Deshpande Shruti , Mohapatra Sidhiparada , Girish N
Published: September 2020

Background

Task-oriented circuit training using a Multi-Activities workstation emphasises goal-oriented tasks practiced in a circuit or series in order to learn a new skill. It can be used for upper limb rehabilitation among stroke patients in a community setting, but there is currently very little evidence available regarding its use in this patient group and setting. This study aimed to explore the influence of task-oriented circuit training using a Multi-Activities workstation on upper limb function among community-dwelling individuals with chronic stroke.

Methods

A pre-test–post-test study was conducted involving 17 community-dwelling individuals with chronic stroke who were attending a stroke rehabilitation centre. Six weeks of task-oriented circuit training was given using a Multi-Activities workstation aimed to improve strength, range of motion and dexterity. Streamlined Wolf Motor Function Test and Chedoke Arm and Hand Activity Inventory were used to measure outcomes. Wilcoxon signed-rank test was used for data analysis.

Results

A total of 12 sessions of task-oriented circuit training using Multi-Activities workstations did not result in any statistically significant differences in outcome measures.

Conclusions

Task-oriented circuit training using the Multi-Activities workstation did not improve upper limb function in community-dwelling individuals with chronic stroke.
Cement augmentation of calcar screws may provide the greatest reduction in predicted screw cut-out risk for proximal humerus plating based on validated parametric computational modelling
Authors: Varga Peter , Inzana Jason A. , Fletcher James W. A. , Hofmann-Fliri Ladina , Runer Armin , Südkamp Norbert P. , Windolf Markus
Published: September 2020

Aims

Fixation of osteoporotic proximal humerus fractures remains challenging even with state-of-the-art locking plates. Despite the demonstrated biomechanical benefit of screw tip augmentation with bone cement, the clinical findings have remained unclear, potentially as the optimal augmentation combinations are unknown. The aim of this study was to systematically evaluate the biomechanical benefits of the augmentation options in a humeral locking plate using finite element analysis (FEA).

Methods

A total of 64 cement augmentation configurations were analyzed using six screws of a locking plate to virtually fix unstable three-part fractures in 24 low-density proximal humerus models under three physiological loading cases (4,608 simulations). The biomechanical benefit of augmentation was evaluated through an established FEA methodology using the average peri-screw bone strain as a validated predictor of cyclic cut-out failure.

Results

The biomechanical benefit was already significant with a single cemented screw and increased with the number of augmented screws, but the configuration was highly influential. The best two-screw (mean 23%, SD 3% reduction) and the worst four-screw (mean 22%, SD 5%) combinations performed similarly. The largest benefits were achieved with augmenting screws purchasing into the calcar and having posteriorly located tips. Local bone mineral density was not directly related to the improvement.

Conclusion

The number and configuration of cemented screws strongly determined how augmentation can alleviate the predicted risk of cut-out failure. Screws purchasing in the calcar and posterior humeral head regions may be prioritized. Although requiring clinical corroborations, these findings may explain the controversial results of previous clinical studies not controlling the choices of screw augmentation.

Weighted-encoding-based image interpolation with the nonlocal linear regression model
Authors: Zhang Junchao
Published: September 2020

An image interpolation model based on sparse representation is proposed. Two widely used priors including sparsity and nonlocal self-similarity are used as the regularization terms to boost the performance of the interpolation model. Meanwhile, we incorporate nonlocal linear regression into this model, since nonlocal similar patches could provide a better approximation to a given patch. Moreover, we propose a new approach to learn an adaptive sub-dictionary online instead of clustering. For each patch, similar patches are grouped to learn the adaptive sub-dictionary, generating a more sparse and accurate representation. Finally, weighted encoding is introduced to suppress tailing of fitting residuals in data fidelity. Abundant experimental results show that our proposed method achieves better performance compared to several state-of-the-art methods in terms of subjective and objective evaluations.
Multiband metamaterial selective absorber for infrared stealth
Authors: Zou Jinglan , Zhang Jianfa , He Yuwen , Hong Qilin , Quan Cong , Zhu Zhihong
Published: September 2020

Nanostructured selective absorbers have widespread applications ranging from artificial color to thermophotovoltaics and radiative cooling. In this paper, we propose a metamaterial selective absorber with a metal–insulator–metal structure for infrared stealth. It can realize multiband absorption, and one sharp peak is at 1.54 µm, which can be used to reduce the scattering signals in laser-guided missiles. The other two relatively broad absorption peaks are at 2.83 µm and 6.11 µm, which can match the atmospheric absorption band. It can reduce up to 90 % of the detected infrared signals while maintaining a relatively high level of thermal emission capability. The dependence of the spectral characteristics on the incident angle is studied. The infrared signatures of the structure could be suppressed across a wide temperature range.
Tracking reference phase with a Kalman filter in continuous-variable quantum key distribution
Authors: Huang Biao , Huang Yongmei , Peng Zhenming
Published: August 2020

The continuous-variable quantum key distribution with a local local-oscillator is extremely sensitive to the phase compensation noise caused by the inaccurate reference phase estimation. In order to overcome the influence of slow drift caused by the residual optical frequency difference, we utilize a vector Kalman filter to estimate and track the reference phase from pilots. The fast drift and slow drift are taken into account in the variation of the reference phase, so that phase estimation becomes more accurate than the conventional scalar Kalman filter. The mean square error of reference phase estimation is deduced theoretically, and the specified frame is designed to estimate the phase noise variance in real time. In simulations, the performances involving of the estimation accuracy, the actual excess noise and the secret key rate are compared between with four different phase estimation methods. The simulation results show that the vector Kalman filter is superior to the other methods, even though under a serious phase noise and a large optical frequency difference.
Single-pixel imaging 12 years on: a review
Authors: Gibson Graham M. , Johnson Steven D. , Padgett Miles J.
Published: August 2020

Modern cameras typically use an array of millions of detector pixels to capture images. By contrast, single-pixel cameras use a sequence of mask patterns to filter the scene along with the corresponding measurements of the transmitted intensity which is recorded using a single-pixel detector. This review considers the development of single-pixel cameras from the seminal work of Duarte et al. up to the present state of the art. We cover the variety of hardware configurations, design of mask patterns and the associated reconstruction algorithms, many of which relate to the field of compressed sensing and, more recently, machine learning. Overall, single-pixel cameras lend themselves to imaging at non-visible wavelengths and with precise timing or depth resolution. We discuss the suitability of single-pixel cameras for different application areas, including infrared imaging and 3D situation awareness for autonomous vehicles.

Maskless lithography for versatile and low cost fabrication of polymer based micro optical structures
Authors: Khan Muhammad Shaukat , lachmayer Roland , Roth Bernhard
Published: August 2020

For applications in optical communication, sensing or information projection in automotive lighting, polymer based optical devices are of keen interest. Optical structures such as waveguides and gratings are basic blocks for these devices. We report on a simple, versatile, and yet low-cost fabrication method suited for both binary and multilevel diffractive microstructures as well as multimode optical waveguides in polymers. The fabrication of the diffractive structures, i.e. gratings, with two and multiple levels, is achieved by using a maskless optical lithography system employing a spatial light modulator. With the same system, waveguide cladding structures are realized by stitching of multiple single exposure patterns. For replication of these structures on polymer, e.g. polymethyl methacrylate (PMMA), a lab-made hot embossing machine is used. We then employ UV curable material and doctor blading to realize the waveguide cores. The created diffractive and waveguide structures are characterized in terms of diffraction efficiency and optical propagation loss, respectively, showing good optical quality and performance. With our fabrication system we have demonstrated a diffraction efficiency of 71% for multilevel grating structure and a propagation loss for stitched waveguides of 2.07 dB/cm at a wavelength of 638 nm. These basic elements will be employed to realize entire optical measurement systems for applications in sensing and integrated photonics in the next step.
To what extent is ‘thinking on your feet’/reflection-in-action relevant to the role of Further and Higher Education Examination Invigilators? Implications for examination policy and practice
Authors: Minott Mark A
Published: September 2020

The aim of this small-scale grounded approach qualitative study was to examine the extent to which the skill of ‘thinking on your feet’/reflection-in-action is relevant to the role of Further and Higher Education Examination Invigilators particularly during the phases of an examination where students are present. The importance of this study rested in the fact that there is a paucity of research which examines the role of examination invigilators at the further and higher education levels. Therefore, it aids in filling a literary gap and gives them a ‘voice’ in the research literature. Study participants were six examination invigilators, working in a London Further Education College. Purposeful convenience or opportunity sampling was used in their selection. Interviews and documentary analysis were the research methods used. The main research question was: ‘To what extent is ‘thinking on your feet’/reflection-in-action relevant to the role of Further and Higher Education Examination Invigilators? This also formed the topic for this paper’. The findings revealed the fact examination invigilators have a common understanding of the research term ‘thinking on your feet’/reflection-in-action, and rated it relevant, very relevant and extremely relevant to their role. Relevance was linked to its usefulness i.e., usefulness in various circumstances; decision making; preventing mistakes and uncovering students’ duplicity. The implications of the findings are discussed.

A clinical case of aromatase excess syndrome associated with 15Q21.2 duplication
Authors: Kasyanova Yulia V. , Chernyak Irina Yu. , Voronina Inobatchon K. , Kalinchenko Natalia Yu.
Published: August 2020

Aromatase excess syndrome (SIA) is a rare autosomal dominant disease caused by increased extraglandular conversion of androgens to estrogens. SIA is characterizedby early gonadotropin-independent hyperestrogenemia, causing pre-pubertal gynecomastia in boys and premature isosexual development in girls. Adults patients have short stature, due to the early closure of epiphyses because of hyperestrogenemia. Women usually have macromastia, endometrial hyperplastic processes and the late onset of menopause. In men, there is a moderate decrease of gonadotropins, leading to secondary hypogonadism. SIA in children can be suspected on a combination of the clinical picture of an excess of estrogens, increased levels of estrogens with low levels of gonadotropins after the exclusion of an estrogen-producing tumor. The frequency of occurrence of SIA is unknown, due to the rarity of the disease and the complexity of its molecular and genetic verification. In this article, we describe a clinical case of a 10-year-old patient with a late diagnosis of aromatase overactivity syndrome caused by a 15q21.2 microduplication of the CYP19A1 gene, and conduct a brief review of the literature.

Territórios camponeses no município de Paranã (TO)
Authors: Quirino Tavares Silvaldo , Oliveira Bispo Marcileia
Published: September 2020

Os camponeses, ao produzirem na terra, estabelecem um conjunto de relações sociais que apresentam características próprias. Neste sentido a formação socioespacial de uma comunidade camponesa envolve uma série de relações que ocorrem ao longo do tempo, cujas  práticas camponesas se consolidam e produzem novos arranjos. Isso ocorre por meio da consolidação do modo de vida intrínseco à classe em lugares onde formam territórios por meio da conquista e resistência. Desse modo, o objetivo principal deste trabalho foi analisar o processo de formação territorial, as práticas produtivas e os elementos socioespaciais de resistência da Comunidade Angical em Paranã-To, frente às adversidades presentes na comunidade, por meio da análise de documentos, trabalho de campo, uso de entrevista semiestruturada e relatos orais. Observou-se que a existência e resistência do campesinato em Paranã-To se efetiva muito mais pelo protagonismo dos camponeses diante da necessidade de acesso e permanência na terra, que pelas possibilidades de reprodução social que as relações presentes no campo garantem, como também que o processo de formação e a permanência da Comunidade Angical em Paranã-To, envolvem questões específicas de luta e resistência.

TOLERANSI DAN MILITAN: POLITIK RELASI ANTARAGAMA SISWA MUSLIM KOTA PADANG
Authors: Ashadi Andri
Published: August 2020

Comfortable with people who different principles/religions and respecting these differences (tolerant), is often suspected of weakening one's religious commitment. Therefore, tolerance is often interpreted as simply allowing differences with all their uniqueness while refraining from all these uniqueness. Through surveys, in-depth interviews, analysis of Homi K. Bhabha's third space, and Frantz Fanon's theory of identity, especially towards Muslim students at Don Bosco Padang High School, this paper proves the opposite. These Muslim students who attend school in a predominantly Christian environment do show a fairly high tolerance, for example being willing to be part of diversity and to be empathetic. However, this coincides with the strengthening of militant attitudes such as seriousness in seeking religious knowledge even outside of school. Also their critical attitude towards school policies that do not accommodate Islamic values.

This paper looks at applications of visual mapping in post-secondary courses to engage university students more deeply from the very beginning of a course, through creating visuals to which students can be constantly referred. We discuss our efforts to design visuals of learning outcomes, objectives, concepts, and processes in multiple courses. We will highlight the process we used to build the graphics and keyways these graphics improve the communication and understanding of learning outcomes, content, themes, and processes, primarily via knowledge visualization and visual perceptual learning. We also discuss sharing our discoveries with colleagues to help further develop our understanding of this approach.

Published: August 2020

Bridge specifications do not consider the effect of parapet stiffness in the analysis and design of reinforced concrete slab bridges. This paper performs a parametric investigation using finite element analysis (FEA) to study the effects of parapet stiffness on live load-carrying capacity of two-span, three-and four-lane concrete slab bridges. This study analyzed 96 highway bridge cases with varied parameters such as span-length, bridge width, and parapet stiffness within practical ranges. Reinforced concrete parapets or railings, built integrally with the bridge deck, were placed on one and/or both sides of bridge deck. The longitudinal bending moments calculated using the FEA results were compared with reference bridge cases without parapets, as well as AASHTO Standard and LRFD specifications. The FEA results presented in this paper showed that the presence of concrete parapets reduces the negative bending moments by 15% to 60% and the positive bending moments by 10% to 45%. The reduction in longitudinal bending moments can mean an increase in the load-carrying capacity of such bridges depending on the parapet stiffness. This investigation can assist engineers in modeling the actual bridge geometry more accurately for estimating the load-carrying capacity of existing concrete bridges. Hence, new bridges can be designed by considering the presence of concrete parapets. Parapets can be used as an alternative for strengthening existing one and two-span reinforced concrete slab bridges.

Dissolved Oxygen (DO) is one of the most important parameters reflecting the ecological health of the river. DO supply must be maintained to support the life of aquatic organisms. DO supply obtained by oxygen transfer from the atmosphere to water. This research aimed to determine reaeration (continuous addition of oxygen) coefficients (KR) of Bedadung Downstream using the exchange of DO deficit. This approach uses the rate of mass transfer of oxygen from the air to the river water. The raw data was obtained by measuring stream-flow, temperature, and DO at three observed stations segment Balung district, Jember. The result showed the values of the reaeration coefficient (3 stations) were 36,084, 47,397, and 83,114 /day sequentially and tended to line up. The amount of KR obtained from the oxygen deficit and travel time of river water. The average KR was 55.532/day. High KR values indicate the ability of rivers that can supply oxygen naturally.

Palasari Reservoir is the largest reservoir on the Bali island that serves as a water provider to meet the surrounding community's needs. The condition of the reservoir directly adjacent to the Palasari Forest makes the vegetation area around the reservoir play an essential role in maintaining groundwater reserves and reducing erosion in the reservoir area. This study aims to analyze the structure of vegetation and diversity and conservation efforts in the Palasari Reservoir green belt area. The method used is the density index, Shannon-Wiener index, the Simpson index, and the importance value index (INP) to determine plants' ecological position in a community. The results showed that the plants that had a role in the Palasari Reservoir green belt community included bananas, mahogany, and spathodea, which were demonstrated by the highest INP's ranging from 20.83%, 20.24%, and 19.80%. These three types of plants are adaptive and can reduce erosion. The value of plant diversity in the study area is moderate, with the dominance of species diversity at the tree level. Efforts to conserve green belts sustainably need to be done by increasing the number of endemic plants in reservoir areas such as pulai and bayur. Every element of society needs to watch out for it to maintain the regional identity.
Za dyplomem? Migracje młodych Polaków do miast akademickich
Authors: Datko Anna
Published: September 2020

The 21st century is an age of mobility. Young Poles have also adapted to this trend – they migrate both abroad and within the confines of their own country. In the paper the author presents the migration to Polish academic cities, to which people arrive because of beginning their studies. But they do not only want to graduate from a university. Moving from their hometown entails too some bigger aims, such as launching a successful professional career, or staying and living in a big city and in consequence being a member of the metropolitan middle class. Academic education is considered due to its usefulness in gaining these aims (through the instrumental role of higher education) – and studies are more and more only a legitimization of a permanent migration to a metropolis.

Authors: Kaczmarek Urszula
Published: September 2020

Głównym celem pracy jest opis i ocena wdrażania koncepcji slow city w małych miastach, położonych w strefach oddziaływania dużych miast. Podmiotem badań są dwa miasta: Murowana Goślina w aglomeracji poznańskiej (Polska) i Schneverdingen w obszarze metropolitalnym Hamburga (Niemcy). Analizie poddano zasoby lokalne obu miast, takie jak: walory środowiska przyrodniczego, dziedzictwo kulturowe, funkcje gospodarcze, infrastruktura społeczna i turystyczna oraz polityki miejskie związane z uzyskaniem certyfikatu członkostwa w organizacji międzynarodowej, jaką jest sieć Cittaslow. Stwierdzono szereg podobieństw wymienionych zasobów przy jednoczesnym ich różnym wykorzystaniu jako czynników rozwoju lokalnego. Na podstawie wyników badań społecznych (wywiady z przedstawicielami władz lokalnych i ankieta wśród mieszkańców) wykazano, że w procesie wdrażania idei slow city kluczową rolę odgrywają elementy kapitału społecznego, w tym wiedza i determinacja władz lokalnych oraz świadomość i zaangażowanie mieszkańców.

Adenosine deaminase (ADA) deficiency is a form of severe combined immunodeficiency. Aberrant mutations in the ADA gene result in loss of ADA activity and the toxic accumulation of metabolites that damage both immune and non-immune organs. While patients with complete ADA deficiency present during infancy with failure to thrive, recurrent bacterial, viral and fungal infections, those with incomplete (partial) deficiency may present at a later age with milder symptoms associated with reduced T, B, and NK cell subpopulations. Based on experience in Canadian centres, we provide management guidelines for patients with ADA deficiency, including a treatment algorithm for use of hematopoietic stem cell transplantation, gene therapy, and enzyme replacement therapy.

Statement of novelty: Herein, we define guidelines for the management and treatment of patients with ADA deficiency.
