Background

Decades of political and economic instability have taken a significant toll on health outcomes among children in Iraq. In a health system with optimal resources, five-year rates of survival for childhood cancer would exceed 80%; however, a study in Iraq demonstrated a much lower survival rate of 50%, reflecting a disrupted health care infrastructure. Under such conditions, it is a struggle to sustain good treatment outcomes. The aims of the present study are to: i) estimate the median time from initial presentation to diagnosis of childhood cancer at a tertiary center in Iraq; and ii) examine sociodemographic and clinical factors associated with delay in diagnosis in this vulnerable population.

Methods

A cohort of 346 children presenting for cancer care between January 1-December 31, 2012 was included in the study. Data were obtained through structured interviews with caregivers and from medical charts. The median total delay in cancer diagnosis was calculated in addition to the median patient delay and physician delay. Factors associated with delay in diagnosis were also examined.

Results

The majority of the patients were less than five years of age and 59% were boys. The median number of days from the onset of symptoms to diagnosis was 55 (range: 3-1,093). This was largely due to physician delay. Clinical factors associated with a longer delay to diagnosis included number of doctors visited, as well as tumor location and type.

Conclusions

Despite recent advances in cancer treatment outcomes, there are persistent disparities between high-resource versus low- and middle-income countries in childhood cancer survival. Lack of access to care, medication shortages, and inadequate access to medical equipment fuel these disparities. Such factors contribute to delay in access to care and increased mortality risk for children suffering from cancer. The situation will continue unless action to improve access to quality care is taken at national and international levels.

Published: July 2021

In this paper, the analysis of a numerical study for consolidation analysis of short bored pile subjected to axial loads is presented. An analysis of short-bored pile is performed using finite element analysis software Abaqus CAE with the base of procured experimental data in sand media and a comparative analysis on Ansys FEA. Three models in combination of pile and footing system were developed by the application of incremental axial load for which the displacement upon each load was analyzed taking in consideration the stresses and strains. A parametric study was conducted to study the effect of load on and it’s observed displacement on the pile with or without footing. A close correlation is found between the results obtained by the FE models and the Experimental Model solution. The results indicates that the load bearing capacity of pile–footing system increases drastically when both acts together instead of acting individually.

Four central rivers of Bangladesh were selected for this research. The name of the rivers is Buriganga, Dhaleshwari, Shitalakshya and Meghna. The Electrical Conductivity (EC), pH, Total Dissolved Solid (TDS), and Salinity of the four river waters were evaluated. The EC values of the water of the Buriganga, Dhaleshwari, Shitalakshya and Meghna rivers were found to be 366.0, 299.2, 290.4 and 130.8 µS/cm respectively. Similarly, the pH values of 7.67, 7.38, 7.30 and 7.18 were found for the river waters of the Buriganga, Dhaleshwari, Shitalakshya and Meghna respectively. The EC and pH values were found higher for the Buriganga river water than that of the other three river waters. The TDS and salinity of the Buriganga river water were found 180 mg/l and 0.72% respectively. On the other hand, the TDS and salinity of the Meghna river water was found lower compared to the other three rivers. From this research, this is clear that the quality of the Meghna river water is much better than the river waters of the Buriganga, Dhaleshwari, and Shitalakshya. The quality of the Buriganga river water was found inferior. Dhaka city, the capital of Bangladesh, stands on the bank of the Buriganga river, and as a result a large number of unban waste goes directly to the river Buriganga. As a result, the water of Buriganga became polluted. This investigation proved that the Meghna river water quality is still much better and suitable for many applications.

Morinda lucida Benth (Rubiaceae) is a versatile plant used in traditional medicine for the treatment of a variety of ailments and the claims of its efficacy are particularly remarkable in the treatment of infections and immuno-inflammatory disorders. This study evaluates the anti-inflammatory properties of methanolic stem bark extract and fractions of M. lucida and also identifies the phytochemicals responsible for its anti-inflammatory activity. The crude extract was subjected to liquid- liquid partitioning successively with n- hexane, ethylacetate, butanol and water. High performance liquid chromatography (HPLC) of the four fractions and Vacuum Liquid Chromatography fraction (VLC) of the promising fraction was evaluated. The effect of the fractions on egg albumen induced rat paw oedema were also evaluated. Anti-inflammatory activity of the fractions was further screened using xylene induce ear oedema models and human red blood cell membrane stabilization test. Ulcerogenic test on the normal stomach mucosa was also evaluated. The result of the egg albumen induced rat paw oedema showed that the butanol fractions maximally inhibited egg albumen induced effect at 400 mg/kg (70%) and 200mg/kg (67.5%) after 180 minutes compared to the positive control, ibuprofen (20mg/kg) with 100% inhibition after 180 minutes. The result of the xylene induced ear oedema showed that the inhibition produced by 100 µg/ear of the Butanol fraction (BF) was 56.67 % and was greater than inhibition produced by 200 µg/ear of ibuprofen (38.89 %). HPLC analysis of the fractions revealed the following phytocompounds; Cytreo- a-pyrone, Cytosporin- J and Waol A. Ulcerogenic test was negative at the doses of 200 mg/kg and 400 mg/kg of the fractions when compare with the indomethacin (positive control) at dose of 50 mg/kg. Human red blood cell membrane stabilization assay showed that BF-VLC 2 (Dichloromethane: methanol (8:2) VLC of Butanol fraction) exhibited concentration dependent inhibition of heat-induced haemolysis while other extract showed a non- concentration dependent inhibition of haemolysis when compared to the standard, ibuprofen. These findings suggest that the stem bark of M. lucida possess promising anti-inflammatory phytocompounds which justify its use in ethno-medicine.

Authors: Kazi Madina Maraz  , Ruhul Amin Khan
Published: July 2021

Microorganisms or microbes are microscopic organisms that exist as unicellular, multicellular, or cell clusters. Microorganisms are widespread in nature and are beneficial to life, but some can cause serious harm. They can be divided into five major types: Bacteria, Archaea, Fungi, Protozoa, and Viruses. Microbes are everywhere in the biosphere, and their presence invariably affects the environment that they are growing in. Microorganisms are beneficial in producing oxygen in environment, decomposing organic material, medicine, providing nutrients for plants, and maintaining human health, but some can be pathogenic and cause diseases in plants and humans. They perform a key role and act as main engineers in governing all ecological processes. They act as universal catalyst and provide ecological transformations. Regardless of whether they influence human health and welfare favorably or unfavorably, microorganisms are capable of profound influences on life. That is to say, it is an integral part of our lives, and therefore acquiring knowledge about it should also be essential and the main thing.

Published: July 2021

Magnesium (Mg) is an essential electrolyte for living organisms. It is the fourth most abundant mineral in the body. Although Mg is usually found in hard water and high-fiber diets, wide use of soft water and refined flour impose people at risk of Mg deficiency. Imbalances in Mg status and Mg deficiency may result in a variety of complications associated with the immune, cardiovascular, urinary, nervous, and respiratory systems. Because of the important roles of magnesium in the prevention and treatment of many diseases, several studies are focusing on the correlation between Mg status and Coronavirus disease 2019 (COVID-19). The present study reviewed several types of research to indicate the importance of monitoring of Mg status as well as the possible role of Mg supplementation for supportive treatment in COVID-19 patients. The results indicated that Mg deficiency could be a risk factor for multi-organ dysfunction in COVID-19 infection. Mg supplementation improves functions of the immune, cardiovascular, nervous, urinary, and respiratory systems through different mechanisms. Suppression of cytokine storm, bronchodilation, antithrombotic function, a decrease of arterial blood pressure, preventing electrolyte imbalance, increase stress resistance are some of the related mechanisms. These findings may provide a reference regarding the possible beneficial effects of the Mg supplement as an inexpensive, safe, and easily available drug for supportive treatment in COVID-19 patients.

Perhitungan harga pokok produksi terhadap suatu produk atau jasa sangat penting dilakukan untuk menentukan harga jual, apabila metode perhitungan harga pokok produk atau jasa yang digunakan tidak sesuai untuk diterapkan di era yang modern seperti ini, maka akan terjadi distorsi biaya. Distorsi timbul karena adanya ketidakakuratan dalam pembebanan biaya, sehingga dapat mengakibatkan kesalahan dalam penentuan biaya, pembuatan keputusan, perencanaan dan pengendalian. Tujuan dari penelitian ini adalah untuk mengetahui bagaimana penentuan tarif jasa rawat inap dengan menggunakan activity based costing dan mengetahui besarnya perbandingan tarif jasa rawat inap dengan menggunakan sistem tradisional dan activity based costing system, yang dapat dijadikan acuan dalam menerapkan tarif jasa rawat inap pada Rumah Sakit Umum Haji Medan. Metode analisis yang digunakan adalah metode deskriptif komparatif yaitu menganalisis tarif rumah sakit saat ini, menghitung tarif berdasarkan activity based costing, kemudian membandingkan tarif jasa rawat inap rumah sakit berdasarkan activity based costing dengan realisasinya. Metode pengumpulan data dalam penelitian ini yaitu penelitian kepustakaan, wawancara, dan dokumentasi. Hasil penelitian diketahui bahwa perhitungan menggunakan activity based costing memberikan hasil yang berbeda. Hasil perhitungan dengan menggunakan sistem activity based costing dibandingkan dengan tarif yang ditentukan rumah sakit memberikan hasil yang lebih mahal pada kelas Super VIP, kelas II, dan kelas III. Sedangkan untuk kelas Suite Room, kelas VIP, dan kelas I memberikan hasil yang lebih murah.

A presente pesquisa objectivou evidenciar a importância da Geodiversidade para o desenvolvimento do Geoturismo, bem como inventariar e avaliar os atractivos turísticos naturais do Distrito de Moatize, de modo a perceber suas potencialidades. Os procedimentos metodológicos aplicados para a realização deste estudo, assentam na pesquisa bibliográfica, trabalho de campo, entrevistas semi-estruturadas e informais; e trabalho de gabinete. De igual modo, com um receptor GPS foram colectados pontos (atractivos turísticos) e, posteriormente inseridos em ambiente de SIG- Sistema de Informação Geográfica (software ArCGIS 10, versão ARCMap 10.3) permitindo a espacialização dos atractivos em um mapa. Na mesma perspectiva, aplicou-se a Metodologia de Hierarquização de Atractivos Turísticos exposta pela OMT e adaptada pelo CICATUR. Para a caracterização dos potenciais atrativos, efetuou-se uma seleção através da pesquisa de campo, o que possibilitou uma breve inventariação turística do local, utilizando os formulários de inventariação da proposta metodológica do Ministério do Turismo (Brasil, 2006). Da pesquisa efetuada, os resultados evidenciam a existência de vários atractivos naturais com elevada potencialidade para a prática da actividade geoturísitica. Contudo, apesar da inestimável potencialidade, percebe-se que os atractivos são praticamente desconhecidos pelo público, embora apresentem elevada sigularidade. Os atractivos turísticos inventariados na região estudada estão extritamente ligados aos elementos da geodiversidade, nomeadamente: Nascentes hidrotermais de Nhaondue e Mawhira 1 e 2, respectivamente; Cavernas de Nhaondue e Phiriganga, Paisagem do Mirante da comunidade de Nhaondue, cascatas do rio Moatize, Monte Zobue, Rocha Cogumelo e Pinturas Rupestres de Nakalata. Com uma boa estruturação destes atractivos, Moatize poderá registar ganhos significativos no sector turístico resultante da demanda pelos seus serviços e/ou produtos turísticos, podendo contribuir assim, na melhoria das condições de vida das comunidades locais e quiçá no desenvolvimento da província e do país de modo geral.
Dedans et contre le patrimoine
Authors: Giromini Patrick

There are the Alps, the Alpine space, and there is heritage or heritages, depending on the meaning of the term and on the position adopted with regard to the questions raised by this notion. Heritage is not only something that exists and to which we are attached, but it should also be possible to produce it. It is this production that is addressed in these brief reflections on architectural works that attempt to combine heritage and “montagnité”.
As soon as the mountain is built upon, the problem of form and, therefore, of its shaping arises. It is the latter that requires production, i.e. a way of thinking that is capable of thematising both the mountain and the heritage. But what are we talking about when we apply the heritage label to Alpine architecture? Is this what is commonly defined as edilizia rurale (rural housing)? Or is it the architectural work that interprets the edilizia rurale and, in a way, absorbs it?
Assuming that the heritage regime in the mountains is part of the variation and not the fixity of a notion such as that of the monument, and that the notion of heritage informs and conforms every architectural project in the mountains, it is possible to put forward a second hypothesis and to affirm that both the edilizia rurale and the architectural projects that transform it, operating within and against it, are heritage. For the latter, however, the rules that Adolf Loos wrote for those who build in the mountains remain valid.
Lentius, profundius, suavius, tre coordinate dell'abitare contemporaneo
Authors: Rizzi Chiara
Published: July 2021

The aphorism lentius, profundius, suavius of Alexander Langer overturns the most famous citius, altius, fortius. It is both a program and a vision to face the most urgent challenges of our time.
Outdoor is the priority action context to design possible ways of reconciliation with the environment, the only way to rediscover the balanced integration with nature that Adriano Olivetti indicated as an antidote to the harmfulness of the urban environment.
Nature plays a decisive role in our society. According to the German philosopher Gernot Böhme, this general reference to nature on the one hand is indicative of a desire to compensate for a lifestyle that is increasingly distant from its rhythms and its essence, on the other it represents a profound and radical removal.
The pandemic has definitively undermined some of the dominant paradigms, leading to the establishment of a new phenomenology of nature based on perception. The health issue has quickly, and perhaps irreversibly, changed our lifestyles and our relationships with nature.
In high-altitude contexts, the archetypes of architecture become the concepts through which architecture redefines its dialogue with the landscape by innovating its grammar and semantic relationships. A complex dialogue that triggers new genealogies and belonging in which design solutions become an opportunity for experimenting and innovating processes, forms and technologies.
The following projects address these issues with respect to two founding themes of architecture: the refuge and the threshold.

Objective The current study aims to explore precipitating and social risk factors for internet addiction (IA) in university undergraduate students, and to provide evidence for interventions and the early prevention of IA in different genders.Methods Four thousand eight hundred and fifty-eight college sophomores completed an online survey on their internet use-related behaviours and social risk factors.Results We found that more male (8.3%) than female students (5.4%) had moderate and severe IA. The main online activity in the moderate and severe IA groups was online gaming in males and online streaming in females. Roommates engaging in similar internetbased entertainment was a risk factor of IA only for males, while not being in a romantic relationship was a risk factor of IA for females only. Infatuation with the internet before college and adjustment problems for college life were shared risk factors for both genders in the mild and moderate IA groups.Conclusion IA was a common phenomenon in college students with shared and unique precipitating and social risk factors in males and females. The gender-sensitive risk factors for IA warranted earlier and individualized intervention and prevention strategies for IA in this population.
