Published: July 2020

As coronavirus disease 2019 (COVID-19) spreads worldwide, there have been few reports of infections among the cancer population, although more than six million cases have been confirmed. Here we studied a surgical specimen from a patient with colon cancer and COVID-19 and two tissue microarrays comprising 103 colorectal cancer and 108 enterocyte cases pathologically. The results showed that, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleocapsid antibody was positively expressed in colon cancer tissues. Moreover, the angiotensin converting enzyme 2 (ACE2) was overexpressed in both colorectal cancer tissue microarray and tumor tissue from this patient, with a positive rate as high as 93.2%. Finally, this case of SARS-CoV-2 infection in colon cancer tumor microenvironment (TME) is a failure of immune homeostasis, due to the decrease in TIA + and Granzyme B+ (GrB) CD8 + T cell proportion and the increase in PD-1 + CD8 + T cell proportion. In summary, we speculate that these three factors may have contributed significantly to infection risk and severity in the patient.

Published: July 2020

Background
Surgical Site Infections (SSIs) are among the leading causes of the postoperative complications. This study aimed at investigating the epidemiologic characteristics of orthopedic SSIs and estimating the under-reporting of registries using the capture-recapture method.
Methods
This study, which was a registry-based, cross-sectional one, was conducted in six educational hospitals in Tehran during a one-year period, from March, 2017 to March, 2018. The data were collected from two hospital registries (National Nosocomial Infection Surveillance System (NNIS) and health information management database (HIM)). First, all orthopedic SSIs registered in these sources were used to perform capture-recapture (N = 503). Second, 202 samples were randomly selected to assess patients` characteristics.
Results
Totally, 76.24% of SSIs were detected post-discharge. Staphylococcus.aureus (11.38%) was the most frequently detected bacterium in orthopedic SSIs. The median time between the detection of a SSI and the discharge was 17 days. The results of a study done on 503 SSIs showed that the coverage of NNIS and HIM was 59.95% and 65.17%, respectively. After capture-recapture estimation, it was found that about 221 of orthopedic SSIs were not detected by two sources among six hospitals and the real number of SSIs were estimated to be 623 ± 36.58 (95% CI, 552–695) and under-reporting percentage was 63.32%.
Conclusions
To recognize the trends of SSIs mortality and morbidity in national level, it is significant to have access to a registry with minimum underestimated data. Therefore, according to the weak coverage of NNIS and HIM among Iranian hospitals, a plan for promoting the national Infection prevention and control (IPC) programs and providing updated protocols is recommended.

Published: July 2020

BackgroundTotal hip arthroplasty (THR) is considered as the most effective available method of treatment of end-stage hip osteoarthritis (OA). This surgery can be performed via many different approaches. One of the newly developed technique is called direct anterior approach (DAA). It gains popularity and recognition as the least traumatic to the soft tissues, thus quickening rehabilitation and improving joint stability in the early postoperative period. There are no systematic reviews covering this subject in terms of potential differences in radiological prosthesis placement, and while there is still unsatisfactory evidence concerning long-term outcomes of DAA, such review may prove useful in the debate. The objective of our study was to systematically collect and review available data from randomized-controlled trials (RCTs) regarding radiographic assessment of prosthesis placement after total hip arthroplasty using direct anterior approach compared to other common approaches.MethodsA systematic review of randomized controlled trials (RCTs) will be conducted. SciFinder, Scopus, ScienceDirect, PubMed, Embase, Clinical Key and The Cochrane Library databases will be searched without restriction to date up to June 2020. Primary outcomes will include measurements related with the radiological analysis of trials comparing use of DAA to other approaches used for THR, containing at least two of the following: femoral stem alignment, mean radiographic cup inclination, mean radiographic cup anteversion, mean radiographic cup abduction, position in Lewinnek's safe zone. Study selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the methodological appraisal of the studies will be assessed by the Cochrane Risk-of-Bias Tool for RCTs. DiscussionThis systematic review will provide missing information regarding influence of differences between DAA and other surgical approaches in total hip replacement on prosthesis implants placement in case of femoral stem and cup. This may result in improving knowledge and awareness of surgeons, improving patients satisfaction and functional outcome and lowering the risk of hip dislocations and other complications.

Research on Distributed Data Stream Mining of Financial Risk Based on Double Privacy Protection
Authors: Zhao Yuhao
Published: July 2020

With the advancement of network technology and large-scale computing, distributed data streams have been widely used in the application of financial risk analysis. However, while data mining reveals financial models, it also increasingly poses a threat to privacy. Therefore, how to prevent privacy leakage during the efficient mining process poses new challenges to the data mining technology. This article is mainly aimed at the current privacy data leakage in financial data mining, combined with existing data mining technology to study data mining and privacy protection. First, a data mining model for dual privacy protection is defined, which can better meet the characteristics of distributed data streams while achieving privacy protection effects. Secondly, a privacy-oriented data stream mining algorithm is proposed, which uses random interference technology to effectively protect the original sensitive data. Finally, the analysis and discussion of the algorithm in this paper through simulation experiments show that the algorithm is feasible and effective, and can better adapt to the distributed data flow distribution and dynamic characteristics, while achieving better privacy protection effects, effectively Reduced communication load.

Published: July 2020

OBJECTIVESAntegrade cerebral perfusion (ACP) under moderate hypothermic circulatory arrest is used during total aortic arch replacement surgery (TARS) in patients with acute type A aortic dissection, but it is associated with high mortality and morbidity. We hypothesized that combining ACP with retrograde inferior vena caval perfusion (RIVP) improves outcomes.METHODSThis pilot study was prospective, randomized, controlled and assessor-blinded. Patients scheduled for TARS were randomly treated with either ACP or RIVP + ACP. The primary outcome was a composite of mortality and major complications including paraplegia, postoperative renal failure, severe liver dysfunction, and gastrointestinal complications. Secondary outcomes included neurological complications, length of intubation and requirement of blood products.RESULTSA total of 76 patients were recruited (n = 38 per group). Primary outcome occurred in 23 patients (61%) in the ACP group and 16 (42%) in the RIVP + ACP group (OR: 0.60, 95% CI: 0.21–1.62; p = 0.31). There was a lower incidence of transient neurological deficits in the RIVP + ACP group (26% vs. 58%, p = 0.006; OR: 0.26; 95% CI: 0.10–0.67). The RIVP + ACP group underwent shorter intubation (25 vs 47 h, p = 0.022) and required fewer blood products (red cells, 3.8 units vs 6.5 units, p = 0.047; platelet: 2.0 units vs 2.0 units, p = 0.023) compared with the ACP group.CONCLUSIONSRIVP + ACP may be associated with lower incidence of transient neurological deficits, shorter intubation and less blood transfusion requirement than ACP alone during TARS. Multi-center, randomized trials with larger samples are required to determine whether RIVP + ACP is associated with lower rates of mortality and major complications.Trial registrationPilot study of a RCT registered in clinicaltrials.gov (NCT03607786)，Registered 30 July, 2018- Retrospectively registered, https://clinicaltrials.gov/ct2/show/NCT03607786.
Seeking Healthcare at Their 'Right' Time: The Iterative Decision Process for Women with Breast Cancer
Authors: Agbeko Anita Eseenam , Arthur Joshua , Bayuo Jonathan , Kaburi Basil Benduri , Kyei Ishmael
Published: July 2020

Introduction: About 85% of breast cancer patients attending Komfo Anokye Teaching Hospital (KATH), Ghana, present with stage III/IV disease. In spite of great investments into the early diagnosis and management of breast cancer, late presentation persists and poses a barrier to realising the possible benefits of the gains made in breast cancer management. This study assessed the symptom appraisal and medical health seeking behaviour of women with either locally advanced or metastatic breast cancer attending breast clinic at KATHMethod: In-depth interviews of women presenting with clinical stage III/IV breast cancer were conducted to explore the women’s care seeking pathways after symptom identification until arrival at KATH from May 2015 to March 2016. Thematic data analysis was conducted using the Andersen behavioural model for health service use.Results: Fifteen women aged 24 – 79 years were interviewed. The time from symptom identification to reporting to KATH was 4 - 24 months. The initial symptom was a breast lump or breast swelling which all the women identified themselves. These were initially appraised as not serious because most importantly, they did not interfere with their daily function. Symptom progression such as prevented them from undertaking their usual economic, social and family function triggered seeking care from health facilities. The availability of money to pay for care and diagnostic investigations influenced the time taken to navigate the referral pathway. While the women initially deferred healthcare for reasons related to their ability to perform economic, family and social roles, ultimately, aggressively pursuing healthcare was also for the same economic, family and social reasons or goals.Conclusion: Deciding to seek care and pursue treatment for breast cancer symptoms may be much more complicated than it appears. Economic, family and social function significantly drive the health seeking process both at the personal and health facility phases of health seeking. Breast cancer education messages must be adapted to incorporate these functional goals and their influence on symptom appraisal and decision making to seek help and not just focus on the breast symptom as an isolated entity.

Published: July 2020

Background: Hip arthroplasty is increasingly performed in young people actively playing sports, professionally active, or treated with steroid drugs in the course of autoimmune diseases. Significantly more often in this group of patients the cause of osteoarthritis is sterile femoral head necrosis. Femoral neck endoprosthesis can be an alternative to pituitary or classical cementlessarthroplastyin the surgical treatment of osteoarthritis.Material and methods: The study group consisted of 27 men aged 32 to 65 years (average 46 years) in whom femoral neck endoprosthesis was implanted (16 on the left side, 11 on the right side).The most common indications for surgical treatment were idiopathic osteoarthritis of the hip (19 patients) and arthrosis due to sterile femoral osteonecrosis (8 patients).Operational access according to Hardinge in the patient's position on the back by embedding a uncemented femoral neck endoprosthesis in ceramic articulation was applied.In the studied group of patients, clinical condition was assessed using the HHS, WOMAC-HIP classification. An assessment of the quality of life was also carried out on the SF-12 scale and pain assessment on the VAS scale.Analyzes were performed before surgery, while the control test was carried out on average over a 5-year observation period.Results: The clinical condition of the examined men on the HHS (49.81 vs 84.05) and WOMAC-HIP (40.59 vs 13.5) scale significantly improved (p <0.05) in relation to the value before surgery.Similar results were obtained in the assessment of quality of life on the SF-12 scale (9.89 points vs. 32 points); (p <0.05) and pain on the VAS scale (6.74 vs 0.58); (p <0.05) during follow-up.Conclusions: The use of femoral neck endoprosthesis in men with hip arthrosis in the mean follow-up of 5 years improved both the clinical condition and the quality of life of the operated patients while reducing the pain.

Authors: Negarandeh Reza , Shayan Shah Jahan , Nazari Rajab , Kiwanuka BSc. Frank , Rad MSc. Sanaz Akhavan
Published: July 2020

Background

Recently, inappropriate use of antibiotics has been correlated with life-threatening side-effects such as adverse effects, increased cost of treatment, and the higher rate of microbial resistance. Besides, it leads to a waste of resources. Therefore, this review sought to determine the pooled prevalence of self-medication with antibiotics, self-medicated illness, reasons for self-medication, antibiotics used for self-medication, source of obtaining antibiotics, the inappropriate practice of antibiotics and suggested recommendations for talking self-medication with antibiotics in the Eastern Mediterranean Region of the World Health Organization (EMRWHO).
Methods

Review conforms to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. Database search was conducted in PubMed, Scopus, Embase, and Web of Science using a combination of keywords which included; antimicrobial, antibacterial, antibiotic, self-medication, self-treatment, self-prescription, non-prescribed, irrational use, inappropriate use, misuse, abuse and Eastern Mediterranean Region of WHO countries. The lists of references of the selected articles were also hand-searched to obtained additional relevant articles. Studies published in English from 2000 to 2018 were included in the review.
Results

We report on data from 60 articles and 49629 participants in this review. The overall prevalence of self-medication with antibiotics in EMRWHO was 47.2% (95% CI 41.6% – 52.9%). Yemen has the highest pooled rate with a rate of 75.0% (95% CI 63.4% − 83.9%), whilst Lebanon has the lowest pooled rate with a prevalence of 28.7% (95% CI 18.4% − 41.8%). The most common illnesses implicated in antibiotic self-medication were upper-respiratory infections and the most common antibiotic was Amoxicillin-Clavulanic acid. The commonest reasons for antibiotic self-medication include: saving time and money. Pharmacies pointed out as the most common source of obtaining antibiotics for self-medication.
Conclusion

Self-medication with antibiotics is significantly high in the member states of EMRWHO. Intervention such as an educational program for communities’ members to change their behaviors, policy on the mechanism of distribution of antibiotics is called for in this area.

Published: July 2020

Background
The spread of ESBLs-producing bacteria has been strikingly rapid in many regions of the world and it causes therapeutic difficulties in everyday practice. The aims of this study were to investigate the prevalence and susceptibilities of ESBLs-producing Escherichia coli isolates from healthy Tibetan yaks in China, to evaluate the activity of drug combinations on ESBLs-producing E. coli isolates.
Methods
From July 2018 to August 2019, a total of 750 nasal swab samples were tested for the presence of E. coli and ESBLs-producing strains. The MICs of 11 antimicrobial agents alone and combinations with sulbactam, EDTA or sulbactam-EDTA against 240 ESBLs-producing E.coli strains were determined by the broth microdilution method.
Results
Overall, 59.87% (n = 449) of the samples were positive for E. coli, 240 (53.45%) of 449 E. coli isolates were confirmed to be ESBLs-producing. The addition of sulbactam to the third generation cephalosporins, amikacin and fosfomycin for all isolates resulted in low MICs, increasing the level of susceptibility from 0, 0 and 0% to 50 ~ 87.5, 4.2 and 100% respectively. The addition of EDTA to fluoroquinolones, doxycycline, florfenicol, amikacin and fosfomycin, showed improved activities and resulted in low MICs, increasing the level of susceptibility from 0, 0, 8.3, 0 and 0% to 4.2 ~ 29.2, 33.3, 33.3, 66.7 and 45.8%, respectively. All other antibacterials (except fluoroquinolones, doxycycline and florfenicol), when combined with sulbactam-EDTA, were found to be more active than combinations only with sulbactam or with EDTA against most of isolates, with lower MIC50s and MIC90s.
Conclusion
In conclusion, ESBLs-producing E. coli isolates were widespread in healthy Tibetan yaks in China. ESBLs-producing E. coli isolates exhibited varying degrees of multidrug resistance. This study these findings suggested that sulbactam can enhance activity of β-lactams and some non-β-lactams of antimicrobial agents and had a synergistic effects with EDTA in improving activities of some families of antimicrobials.

Published: July 2020

Background: Although transarterial chemoembolization（TACE）has been widely used for spontaneously ruptured hepatocellular carcinoma (HCC), no existing models can be used for survival prediction. Thus, the aim of the present study was to develop and validate a nomogram for risk prediction of HCC rupture after TACE treatment.Methods: The medical records of patients who underwent transarterial chemoembolization therapy from January 2015 to April 2019 at our Hospital were retrospectively screened. HCC was diagnosed by either imaging or histological evaluation according to the AASLD guideline. Factors that were found to be significant in univariate analysis were subjected to multivariate analysis. Factors in the nomogram were identified by multivariate Cox hazard analysis. The concordance index was calculated. Results: This study consisted of 55 patients with spontaneously ruptured HCC receiving TACE at our center from January 2015 to April 2019. The median overall survival was 6.4 months, with 0.5-year and 1-year survival being 52.7% and 41.8%, respectively. In univariate analysis, largest tumor size, total bilirubin level, and aspartate aminotransferase level were associated with overall survival. Multivariate analysis suggested that total bilirubin level and the max diameter of the tumors were independent prognostic factors to predict overall survival. Based on these variables, we developed and validated a nomogram for individual patient risk stratification of HCC rupture after TACE treatment. The concordance index for overall survival prediction was 0.748 (95% CI: 0.691-0.805).Conclusions: Based on the nomogram, we have provided an intuitive tool for estimating the prediction of ruptured HCC patients. This study may help to improve the perioperative strategy and treatment outcome.

Background The Schistosomiasis Consortium for Operational Research and Evaluation (SCORE) coordinated a five-year study implemented in several countries, including Niger, to provide an evidence-base for programmatic decisions regarding cost-effective approaches to preventive chemotherapy for schistosomiasis control. Methods This was a cluster-randomised trial investigating six possible combinations of annual or biannual community-wide treatment (CWT), school-based treatment (SBT), and holidays from mass treatment over four years. The most intense arm involved two years of annual CWT followed by two years of biannual CWT, while the least intensive arm involved one year of annual SBT followed by a year without treatment and two more years of annual SBT. The primary outcome of interest was prevalence and intensity of S. haematobium among 100 children aged 9-to-12-years sampled each year. In addition, 100 children aged 5-to-8 years in their first year of school and 50 adults (aged 20-to-55 years) were tested in the first and final fifth year of the study. Results In total, data was collected from 167,500 individuals across 225 villages in nine districts within the Niger River valley, Western Niger. Overall, prevalence of S. haematobium decreased from baseline to Year 5 across all study arms. The relative reduction of prevalence was greater in biannual compared with annual treatment across all arms, however, the only significant difference was seen in areas with a high starting prevalence. Although adults were not targeted for treatment in SBT arms, a statistically significant decrease in prevalence among adults was seen in moderate prevalence areas receiving biannual (10.7% to 4.8%) SBT (p<0.001). Adults tested in the annual SBT group also showed a decrease in prevalence between Year 1 and Year 5 (12.2% to 11.0%), but this difference was not significant.Conclusions These findings are an important consideration for schistosomiasis control programs that are considering elimination and support the idea that scaling up the frequency of treatment rounds, particularly in areas of low prevalence, will not eliminate schistosomiasis. Interestingly, the finding that prevalence decreased among adults in SBT arms suggests that transmission in the community can be reduced, even where only school children are being treated, which could have logistical and cost-saving implications for the national control programmes.
Who Indicates Caesarean Section in Romania? A Cross-Sectional Survey in Tertiary Level Maternity on Childbirth Patients and Doctors' Profiles
Authors: Simionescu Anca Angela , Horobet Alexandra , Marin Erika , Belascu Lucian
Published: July 2020

Background. C-section rate in Romania is the second-highest in the European Union (44.1% in 2017) and the number of C-sections performed in the country increased by 32.1% between 2009 and 2017. We offer for the first time insights into the practice and perceptions of patients and doctors in Romania towards delivery mode and on health system particularities that lead to increased numbers of C-sections. The objectives are 1) to compare the preferred modes of birth among women 2) to draw a profile of patients in whose case the actual birth method is different from the preferred method, and 3) to outline a profile of doctors and patients based on the modes of delivery. Methods. We conduct a statistical analysis based on an observational, analytical, and cross-sectional survey on 117 singleton pregnant women more than 36 weeks in spontaneous labor in tertiary level maternity in Romania. Various statistical tests have been used to indicate statistical significance. Results. Our results show an increase of almost 58% in actual childbirth mode against preferred childbirth by C-sections, rather difficult to justify based only on medical emergencies. There are 22 patients with non-concordant C-section indications between preferred and actual mode of birth, 7 of them (31.8%) preferred natural birth and 15 (68.2%) preferred C-section. Scarred uterus is the most frequent medical indication for C-section (30.7%). Overall, birth and birth pain assessment correlates to preferred and actual delivery modes, but respondents distinguish clearly between birth pain alone and their overall birth experience. The profiles of patients with concordant and non-concordant delivery modes are different, and indicate a statistically significant difference between the preference for delivery and actual birth method. Patients who preferred vaginal birth, but gave birth by C-section, are mature and more educated women, in the middle to the high-income category, mostly attended by consultant doctors and specialists. Doctors’ profiles show that specialists and consultants attend the largest share of non-concordant births, while residents and young senior doctors attend mostly vaginal births. Conclusions. We emphasize health system particularities in Romania as triggers of high C-section rates that favor womens’ preferences against C-section medical indication.
On the crystal chemistry of sulfur-rich lazurite, ideally Na7Ca(Al6Si6O24)(SO4)(S3)–·nH2O

Dark blue lazurite from the Malo-Bystrinskoe lazurite deposit, Baikal Lake area, Eastern Siberian region, Russia, was analyzed by electron microprobe and revealed an unusually high content of total sulfur corresponding to 8.3 wt% S. The relative content of sulfur in sulfate and sulfur in sulfide form was determined by wet chemical analysis. The H2O content was measured by means of differential thermal analysis in combination with mass spectrometry and infrared (IR) spectroscopy. The charge-balanced empirical formula of lazurite calculated on the basis of 12 (Al+Si) atoms per formula unit was (Na6.97Ca0.88K0.10)Σ7.96[(Al5.96Si6.04)Σ12O24](SO4)1.092−(S3−)0.55S0.052− Cl0.04·0.72H2O. The presence of H2O molecules and (S3)– and (SO4)2– groups was confirmed by the combination of IR, Raman, electron paramagnetic resonance (EPR), and X-ray photoelectron spectroscopy (XPS) methods. The idealized formula of lazurite is Na7Ca[Al6Si6O24](SO4)2–(S3)–·H2O, and it is believed that extra-framework cations and anions are grouped into clusters of [Na3Ca·SO4]3+ and [Na4(S3)–]3+. The types of isomorphous substitutions in nosean and haüyne are discussed. Lazurite is a clathrate-type mineral, which may be an effective (S3)– sensor due to the stability of the trisulfur radical anion in isolated cages of the crystal structure. This specific feature makes it possible to study the behavior of this ubiquitous radical anion over larger T and P ranges as compared to free species. This kind of lazurite, with oxidized and reduced sulfur species, seems to be appropriate for the estimation of the fugacity of SO2 and O2 in metasomatic systems forming lazurite-containing rocks. The systematic presence of incommensurate modulations is a unique structural feature of Baikal lazurite and may be an important marker indicating provenance of the mineral.

Published: July 2020

Ensuring Ukrainian enterprises’ personnel sustainability is a real challenge because the structural transformation of the labor market in the context of globalization of the world economy leads to increased competition for qualified personnel. In the Ukrainian labor market, the tendency to imbalance professional and qualification structure is the result of the progress of migration, urbanization, and demographic crisis. Thus, the study aims to develop a procedure for diagnostics and predicting the personnel sustainability of the enterprises due to the construction of the forecast model. The formation of “Predictable Model of the Personnel Sustainability” (“PMPS”), which is based on an analysis of the personnel sustainability indicators and predictors of release, was proposed. Approbation was carried out on the example of the Ukrainian enterprises of a recreational complex. The results of the personnel sustainability forecasting showed that the extent of the violation of the personnel sustainability is significant because the high projected performance of the indicators of fluctuation movement of the personnel and employee turnover changes, the structural components associated with wages indicate its further growth, and trends in the predictors of the violation of sustainability signal the possible dismissal of the personnel in the future.

Would the disappearance of one's building influence his own daydreams, experience, and sense of belonging? Would this person remember it? Would these memories preserve the demolished building? This paper explores people's memories and perceptions upon the demolition of a historical building, and their effect on the produced space and sense of belonging. It documents people's narratives as a way of conserving the building through their memories. The paper focuses on Wikāliẗ ạl-’Anbariyin, a market that dates to the Fatimid period and represents a significant Mamluk architectural style. Its location is at ạl-Mu’iz Street, near ạl-Ạzhar Street, ạl-jmmạliyha district, Cairo. However, nowadays, it is just a ruin with a fence and street vendors next to it, after its demolition in February 2019. The study utilizes qualitative methodology through site visits, observations, and random semi-structured interviews with people in ạl-Muʿiz Street. The collected data is thematically analyzed. The results reveal the diversity of memories and their dependence upon the level of interaction with Wikāliẗ ạl-’Anbariyin. The ability of people's memories to conserve, not only the tangible heritage, building's architectural design and materials, but also the spatial experience, events, and social activities. Furthermore, memories show people's sense of belonging and place attachment, especially to those who used to work there, even after the building's demolition. During site visits, it is remarkable to observe the ability of previous shop owners and workers to conserve their memories about Wikāliẗ ạl-’Anbariyin by using simple elements.

Conservation Techniques of Architectural Heritage and Private Property Legal Rights – Case Study Alexandria, Egypt
Authors: El-Daghar Khaled
Published: July 2020

Conservation projects of architectural heritage primarily aim at preserving the cultural character and protecting the historical and value buildings through a set of techniques/approaches and concepts that deal with valuable urban heritage. These concepts and approaches are sometimes a major obstacle to community development. Thus, for a better understanding of the debate over conservation versus development in terms of ownership and private property legal rights, the study will review the classification of different techniques by applying them at the level of architecture, urban, and society. Hence, these have been classified into three basic levels: building, urban, and community, whereby policies for each type will be reviewed. These arguments will be discussed within the Alexandrian experience in architectural heritage listing and management. Moreover, the study also explores evaluation criteria of historical and value buildings, clarifying the attempts to conserve the architectural heritage in Alexandria. The study focuses mainly on the conflict between conservation techniques and the concept of private property legal rights, and hence, proposing some future measures to address the conflict of interests between conservation on one hand and private property ownership legal rights on the other. In addition, it will present some recommendations for preserving the unique architectural style of the Mediterranean Sea that distinguishes the city of Alexandria. It will also adhere to the remains of this heritage by taking into consideration the legal rights of private property, which can contribute to the conservation techniques of architectural heritage for Alexandria.

Early warning of debris flow is one of the core contents of disaster prevention and mitigation work for debris flow disasters. There are few early warning methods based on the combination of rainfall threshold and geological environment conditions. In this paper, we presented an early warning method for debris flow based on the infinite irrelevance method (IIM) and self-organizing feature mapping (SOFM), and applied it to Liaoning Province, China. The proposed model consisted of three stages. Firstly, eight geological environmental conditions and two rainfall-inducing conditions were selected by analyzing the factors affecting the development of debris flow in the study area, and the rainfall threshold for debris flow outbreak was 150 mm. Secondly, the correlation between various factors was analyzed by IIM, which prevented the blindness of parameter selection and improved the prediction accuracy of the model. Finally, SOFM was employed to predict the test data. Experimental results showed that the IIM-SOFM model had a strong early warning ability. When 25 samples of low-frequency debris flow area were selected, the accuracy rate of the IIM-SOFM model with optimized network structure parameters was 100%, which it was obviously superior to the rainfall threshold method, BP neural network and competitive neural network. Consequently, it is feasible to use the IIM-SOFM model for early warning of debris flow, outperforming traditional machine learning methods.

Objective:

The study aimed to evaluate the influence of storage temperature on immunobiological efficacy and safety in autoimmune rheumatic disease treatment.

Methods:

This observational study included adult patients with autoimmune rheumatic diseases who used immunobiologicals stored at home and were followed up at the rheumatology outpatient clinic of the General University Hospital of Cuiabá, Mato Grosso, Brazil, in 2017/2018. Patients were evaluated regarding disease activity and occurrence of adverse events, and a household survey of the temperature of the storage environment of these drugs was conducted.

Results:

Sixty patients with a mean age of 50.4 years were evaluated. Of these, 39 patients (65%) stored their biological drugs outside the recommended temperature range. Storage of the immunobiological at the incorrect temperature was 76% higher among patients with moderate/high rheumatic disease activity (p=0.003).

Conclusion:

Most patients stored their immunobiologicals outside the temperature range recommended in the package insert, and there was an association between incorrect storage temperature and moderate/high autoimmune rheumatic disease activity.
Management of Market Surveillance Authorities for Construction Products
Authors: Kouros Kyriacos I. , Chrysostomou Christis Z.
Published: July 2020

Background:

The Construction Products Regulation (CPR) entered into full force in the European Union (EU) on 1 July 2013 aiming to improve the free movement of construction products. Several EU Commission Reports acknowledge as one of the main shortcomings, the less than active role of Member States in market surveillance and suggest examining and implementing methods for more efficient prioritisation and organisation of market surveillance activities.

Objective:

The purpose of the paper is to investigate management elements of the Market Surveillance Authorities (MSAs) for construction products in the EU. To this end, and to collect information on the current level of effectiveness of the organisational approach of the MSAs, it is imperative to collect information on the main relevant management activities of the MSAs, i.e. strategic analysis, risk assessment and performance measurement.

Methods:

The paper presents background information on the level of market surveillance in the EU. In order to provide further insight, a survey was carried out to collect information and views from representatives of the Member States’ MSAs of construction products participating in the EU committee “Administrative Cooperation Group for the Construction Products Regulation” (AdCo-CPR).

Results:

Through the findings of investigating management perspectives of the MSAs, it can be concluded that currently, market surveillance of construction products in the Member States markets is limited, and MSAs should consider implementing a quality management system to improve the effectiveness of market surveillance activities as well as to create public value.

Conclusion:

The findings also suggest that further investigation is needed to be related to strategy, risk and performance management of the MSAs in order to enhance performance and effectiveness.

Published: July 2020

Tonic accommodation decreased with age among children. In young adults, late-onset myopia will develop due to occupational near vision demands. This study aims to investigate the accommodation response and facility between children and young adults, in emmetrope (non-myopic) and myope group. The accommodation response and facility of young adults and children were measured using monocular estimation method (MEM), monocular accommodative facility (MAF) and binocular accommodative facility (BAF) with an exposure of near task for 15 minutes. Near task has significantly increased the lag of accommodation in all groups (p<0.05). However, the accommodation facility was not affected by near work in all groups (p>0.05).
Keywords: accommodation response, accommodation facility, myopes, emmetropes.
