THERMAL ANALYSIS OF A PLATE HEAT EXCHANGER (PHE) FITTED WITH CARDING TOOL PATTERNS USING CFD MODELING
Authors: Djemel Hassene , Chtourou Sirine , Kaffel Mohamed , Baccar Mounir
Published: October 2023

Inspired by the wool carding tools, a new plate heat exchanger (PHE) design was developed, tested, and analyzed numerically. The present research work used computational fluid dynamics (CFD) simulations to examine the impact of various parameters, such as the rib type (continuous and discrete), the arrangement type (rectangular, square, and triangular), and the geometrical parameters (transversal and longitudinal pitches) on the PHE hydraulic and thermal performances. A three-dimensional (3D) evaluation of turbulent flow over a plate fitted with carding tool patterns was conducted using the k-ε turbulence model within the Reynolds number range from 400 to 1800. The numerical results were compared to previous experimental research to validate the dependability of the technique, and a mesh independence analysis was performed to confirm the precision and the accuracy of the CFD method. The results show that CFD ANSYS software can effectively predict the pressure drop across the carding tools and provide valuable insights into the fluid flow behavior within the system in terms of calculating the thermal hydraulic performance parameter (THPP) and the thermal effectiveness ε . The ultimate goal of this research work was to identify the ideal arrangement with the highest heat transfer rate and the lowest pressure losses in terms of determining the best THPP. Compared to the conventional chevron-type PHE, the thermal performance of the novel PHE design was enhanced by 25.63% and 47% in terms of nondimensional parameters e and THPP, respectively.

Authors: Lee Jeonghan , Suh Jaewoo , Oh Juseok , Ki Seunghee
Published: October 2023

Background: Internal jugular veins are the most frequently accessed site for central venous catheterization in patient management, whereas complications involving vertebral veins are a rare occurrence.Case: A 73-year-old male suspected to have a urothelial carcinoma was scheduled for elective left nephroureterectomy. During central venous catheterization using the anatomic landmark technique to target the internal jugular vein, a guidewire is inadvertently inserted into the suspected vertebral vein. Following the correction of the catheterization, a radiologist reviewed the preoperative enhanced computed tomography and confirmed that the initially punctured vessel was the vertebral vein. On the third day after surgery, the central venous catheter was removed, and the patient did not exhibit any complications, such as bleeding, swelling, and neurological symptoms.Conclusions: The use of ultrasonography during central venous catheterization is recommended to evaluate the anatomy of the puncture site and prevent misinsertion of the catheter, which can lead to several complications.

Tinnitus detection and characterization requires a carefully elaborated diagnosis mainly owing to its heterogeneity nature. The present investigation aims to find features in Electroencephalographic (EEG) signals from time and frequency domain analysis that could distinguish between healthy and tinnitus sufferers with different levels of hearing loss. For this purpose, 24 volunteers were recruited and equally divided into four groups: 1) controls, 2) slow tinnitus, 3) middle tinnitus and 4) high tinnitus. EEG signals were registered in two states, with eyes closed and opened for 60 seconds. EEG analysis was focused on two bandwidths: delta and alpha band. For time domain, the EEG features estimated were mean, standard deviation, kurtosis, maximum peak, skewness and shape. For frequency domain, the EEG features obtained were mean, skewness, power spectral density. Normality of EEG data was evaluated by the Lilliefors test, and as a result, the nonparametric technique Kruskal-Wallis H statistic to test significance was applied. Results show that EEG features are more differentiable between tinnitus sufferers and controls in frequency domain than in time domain. EEG features from tinnitus patients with high HL are significantly different from the rest of the groups in alpha frequency band activity when shape and skewness are computed.
Spatial distribution of δ18O in rainwater and groundwater to identify areas of recharge in the Colombian Northwest

Published: October 2023

The understanding of the spatiotemporal variability of the water molecule stable isotopes (δ18O and δ2H) in rain and groundwater has been used in hydrogeology to validate recharge zones. In this study, we analyzed the recharge of four aquifer systems located in northwestern Colombia. This region is characterized by highly complex topography, as the Andes Mountain range splits into three branches, two of them included in the study area. The relation in the variation of values of the δ18O‰ between Precipitation (P) and groundwater (GW) was analyzed through the arithmetic expression P/GW; when P/GW is equal or larger than 1, the recharge is direct, and values less than 1 indicate recharge from regional flows. For the purposes of this research, according to statistics criteria, values between 0.98 and 1.02 are considered as 1. It was found that on Bajo Cauca, Occidente and Urabá, the phreatic aquifers are recharged directly with rainwater or after slight evaporation processes, while the recharge of deep aquifers occur through regional flows. The Valle de Aburrá´s phreatic aquifer is also recharged from distant areas; this occurs because the surface has been impermeabilized by urban processes.  The P/GW ratio seems to be useful in identifying recharge processes in regions with higher elevation gradients. In low-lying areas, the applicability of this method should be restricted.

Authors: Muñoz-Pérez Sócrates Pedro , Lozano-Sánchez Jaime Jamill , Ramírez-Silva Diana Mareline , Vallejos-Madianero Joicie Elizabeth
Published: October 2023

Concrete production is characterized by a significant demand for energy and raw materials. The construction, maintenance, and demolition of engineering works cause excessive polluting waste that requires costly disposal. For this reason, alternative reusable materials that improve the mechanical properties of concrete, such as fly ash, are currently being investigated as an effective solution to reduce problems related to environmental impact.  This paper analyzed 80 articles indexed in different databases such as ScienceDirect, IOPscience, Scielo, Ebsco, Scopus, SpringerLink, ProQuest, Dialnet, and Semanticscholar, which were not older than seven years since publication, to conduct an updated systematic review of the use, effect, and influence of fly ash on concrete. The methodologies and designs used to obtain the optimum percentages of 5, 10, and 15% were reviewed, analyzing mainly the results obtained when fly ash is used in concrete. Finally, according to the review carried out, it was concluded that fly ashes improve the mechanical and physical characteristics of concrete, and that the optimum dosage is 10% in substitution of ordinary Portland cement applied in simple concrete.

Authors: YILDIRIM Yıldırım , AKBAŞ Zafer
Published: October 2023

Tüm dünyayı etkisi altına alan koronavirüs pandemisinin siyasi tutumlarla ilişkisini öğrenmek ve siyasetin kriz durumlarında halkın tutum ve davranışlarını yönlendirip yönlendirmediğini öğrenmek amacıyla 767 kişiyle çevrimiçi anket yapılmıştır. Yapılan nicel araştırma sonucunda, alınan önleyici tedbirlere uymanın, bu tedbirlerin yerinde oluşuna/haklılığına olan tutumun, aşı olma niyetinin ve aşının koruyuculuğuna olan inancın siyasi görüşlere göre farklılaştığı bulunmuştur. Ayrıca katılımcıların yapılan Covid-19 açıklamaları bakımından siyasi partilerine, parti temsilcilerinden daha çok güvendikleri, alınan önlem ve tedbirleri kısmen yerinde/haklı buldukları ve çok büyük çoğunluğun bu önlemlere uyduğu görülmüştür. Araştırma sonucunda virüsün kökenine yönelik inançlar bakımından virüsün gerçek olduğuna inanıldığı, ortaya çıkış nedeni bakımından ise ülkelerin ekonomilerini kötüleştirmek ve dünya nüfusunu azaltmak için ortaya çıktığına inanıldığı görülmüştür. Araştırmadan çıkan bir başka sonuç ise katılımcıların televizyon, dergi ve gazetelerin ideolojik nedenlerle ve siyasi yanlılıklarına bağlı olarak virüs haberlerini halka farklı yansıttığını düşündükleridir. Sosyal medyadaki haberlerin ise yanıltıcı, yanlış olduğu görüşündelerdir. Bu çalışma sonucunda salgın hastalık, afet, savaş, ekonomik krizler gibi olağanüstü durumlarda siyasetin, siyasi görüşlerin dikkate alınmasının hem krizin üstesinden gelmede hem de toplumun tüm üyelerini kapsamada önemli bir rol oynayacağı vurgulanmaktadır.

Big data are key building blocks for creating information value. However, information systems are increasingly plagued with useless, waste data that can impede their effective use and threaten sustainability objectives. Using a constructive design science approach, this work first, defines digital data waste. Then, it develops an ensemble artifact comprising two components. The first component comprises 13 machine learning models for detecting data waste. Applying these to 35,576 online reviews in two domains reveals data waste of 1.9% for restaurant reviews compared to 35.8% for app reviews. Machine learning can accurately identify 83% to 99.8% of data waste; deep learning models are particularly promising, with accuracy ranging from 96.4% to 99.8%. The second component comprises a sustainability cost calculator to quantify the social, economic, and environmental benefits of reducing data waste. Eliminating 5948 useless reviews in the sample would result in saving 6.9 person hours, $2.93 in server, middleware and client costs, and 9.52 kg of carbon emissions. Extrapolating these results to reviews on the internet shows substantially greater savings. This work contributes to design knowledge relating to sustainable information systems by highlighting the new class of problem of data waste and by designing approaches for addressing this problem.
"CRISIS OF ART" AND "CRISIS OF AESTHETICS" IN RESEARCH OF POLISH HUMANITIES OF THE SECOND HALF OF THE 20th CENTURY
Authors:   Rivne State University of Humanities, Shevchuk Kateryna
Published: October 2023

In the second half of the 20th century, discussions around the understanding of crisis phenomena that permeated all spheres of human life became more frequent, in particular, the spheres of art and aesthetics were also touched upon. The crisis in the artistic sphere was connected with the general cultural crisis of the late 19th and early 20th centuries, the decline of spirituality, and the relativization of values, primarily moral and aesthetic. Analysis of the crisis in the sphere of artistic practice and aesthetics of the 20th century was the subject of scientific research by several representatives of Polish aesthetics of the second half of the 20th century: R. Ingarden, S. Morawski, B. Dziemidok, and others. The primary attention of these thinkers was devoted to the understanding of transformational processes in modern artistic creativity and the analysis of its influence on aesthetics with a clear emphasis on the importance of the axiological perspective. A thorough analysis of the problems of the crisis in artistic creativity and aesthetics of the 20th century can be found in the works of S. Morawski. He studied the causes and consequences of transformations in artistic creativity since the beginning of the 20th century, in particular, the consequences for the formation of the modern axiosphere, and its role in changing modern aesthetic consciousness. However, S. Morawski's prediction regarding the replacement of aesthetics with anti-aesthetics was not confirmed. On the contrary, art that implements aesthetic values has survived, although the range of aesthetic values has increased significantly. Modern philosophy of art is open to the most controversial artistic proposals. This is because it breaks with those normative principles that limit freedom. The most important thing, however, is that normative and descriptive aesthetics always have an axiological character, which all representatives of Polish aesthetics emphasized in the second half of the 20th century.

Authors: Gulya Marina O. , Zavadovsky Konstantin V.
Published: October 2023

BACKGROUND: This review outlines the features of the pharmacokinetics of the perfusion radiopharmaceutical 99mTc-MIBI, which allows the assessment of myocardial mitochondrial dysfunction, and shows the main clinical applications of the phenomenon of increased 99mTc-MIBI washout rate.
AIM: To systematize the data of fundamental (experimental) and clinical studies evaluating and estimating mitochondrial dysfunction according to myocardial perfusion scintigraphy data and perform meta-analysis of clinical studies in this field.
MATERIALS AND METHODS: PubMed, Scopus, Google Scholar, and eLibrary databases were searched until mid-2023. The following keywords, their combinations, and Russian-language counterparts were used: mitochondrial dysfunction, 99mTc-MIBI, 99mTc-Tetrofosmin, myocardial perfusion scintigraphy, reverse redistribution, washout, and washout rate. In the meta-analysis, a random-effects model was used to calculate the mean difference estimate.
RESULTS: Forty articles were selected for systematic analysis: 13 were experimental, 24 were original clinical papers, 2 were clinical cases, and 1 was a review. Six studies using a case–control design were selected for the meta-analyses. The total number of patients in the systematic review and meta-analysis were 551 and 196, respectively. In the analysis of the literature, the severity of the reverse redistribution phenomenon and 99mTc-MIBI washout rate correlated with mitochondrial and myocardial microstructure, left ventricular contractility and hemodynamics, natriuretic peptide levels, exercise tolerance, coronary atherosclerosis severity, myocardial oxidative metabolism, and risk of cardiovascular events. The meta-analysis showed that the washout rate was statistically significantly accelerated in individuals with cardiac pathologies, relative to controls (mean difference score, 9.5771 [95%]; confidence interval, 6.6001–12.5540; z=6.3053, p 0.0001).
CONCLUSION: The assessment of mitochondrial function by 99mTc-MIBI washout evaluation may provide additional insights into the functional status of cardiac muscles.

Published: October 2023

BACKGROUND: Factors that may trigger episodes of binge eating include mental and physical stress, dietary restrictions of high-calorie foods. In a rodent model it has been shown that intermittent consumption of high-calorie foods causes binge eating regardless of body weight gain.
AIM: To investigate the effect of a novel ghrelin receptor antagonist Agrelax on binge eating in in adult rats after maternal deprivation in early ontogeny.
MATERIALS AND METHODS: Animals were weaned for 180 min from day 2 to day 12 after birth; males 90100 days of age were used in the experiments. In the development of binge eating, animals received a high-carbohydrate diet (Nutella paste based chocolate mixture) for 1 h every day or every third day for 1.5 months. Fifteen minutes before feeding, the chocolate paste was placed within 5 cm of reach with visual contact. Agrelax, a novel ghrelin receptor antagonist, was administered intranasally 1g/1l, 20l for 7 days.
RESULTS: Maternal deprivation induced bindge eating of high-calorie foods in adult rats. When chocolate was given 3 times a week, its consumption increased (p 0.001) in the maternal deprivation group relative to the control group. After a course of administration of agrelax, chocolate consumption did not differ significantly from that in the control group. The daily consumption of standard food did not differ relative to the control group both before and after the course of agrelax administration. When chocolate was given daily, the maternal deprivation rats did not develop food addiction. At the same time agrelax did not induce a change in chocolate consumption relative to the control group.
CONCLUSIONS: The findings suggest new ways to synthesize pharmacological agents of peptide nature based on ghrelin and its antagonists for correction of food addiction caused by psychogenic stresses in ontogenesis.
Modern representations about signaling pathways and protective mechanisms of ferroptosis. A biological role of diffusion of death signals of ferroptotic cells
Authors: Vashchenko Vladimir I. , Sorocoletova Elena F. , Shabanov Petr D.
Published: October 2023

Ferroptosis as the type nonapoptosis adjustable destruction of cells arises and develops by means of difficult signals and regulatory mechanisms. The reactive oxygen species (ROS) used to initiate ferroptosis come from a variety of sources, including iron-mediated Fenton reactions, mitochondrial ROS, and membrane-associated ROS driven by the NOX protein family. Polyunsaturated fatty acid-containing phospholipids are the main substrates of lipid peroxidation in ferroptosis, which is positively regulated by enzymes, such as ACSL4, LPCAT3, ALOXs, or POR. Selective activation of autophagic degradation pathways promotes ferroptosis by increasing iron accumulation to cause lipid peroxidation. In contrast, system Xc-glutathioneGPX4 axis plays a central role in limiting lipid peroxidation, although other antioxidants (such as coenzyme Q10 and tetrahydrobiopterin) can also inhibit ferroptosis. A main nuclear mechanism of cell defense against ferroptosis is the activation of the NFE2L2-dependent antioxidant response by transcriptionally upregulating the expression of antioxidants or cytoprotective genes. Additionally, the membrane damage caused by ferroptotic stimulus can be repaired by ESCRT-III-dependent membrane scission machinery. In this review, we summarize recent progress in understanding the signaling pathways and defense mechanisms of ferroptosis.
Role of oxidative stress in the pathogenesis of autism spectrum disorders
Authors: Belokoskova Svetlana G. , Tsikunov Sergey G.
Published: October 2023

The literature review reflects the contemporary information on the role of oxidative stress in the pathogenesis of autism spectrum disorders. We present data on the importance of genetic predisposition, environmental factors, and epigenetic influences on the development of oxidative stress, which, during critical periods of early brain development, may influence the induction and progression of the disease. The role of mitochondrial dysfunction, immunological disorders, increased permeability of the blood-brain barrier, hypoperfusion of the brain causing or aggravating the redox imbalance in patients with autism spectrum disorders is shown. Analysis of the literature data indicates that the increased content of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione, ceruloplasmin and transferrin in the blood and brain of patients with autism spectrum disorders reflects the activation of compensatory mechanisms. Increased levels of malondialdehyde, xanthine oxidase, nitric oxide in various biological media indicate insufficiency of antioxidant protection system. Taking into account the role of oxidative stress in the pathogenesis of autism spectrum disorders, therapy including antioxidant drugs is indicated for correction of metabolic disorders.

Issues of Sustainable Finance Rating Assessment
Authors:   Southern Federal University, Morozov Serafim A.
Published: October 2023

The formation of a sustainable finance market creates the need for independent and reliable information necessary for making investment decisions. The most important source of such information is ESG-ratings designed to assess the degree of commitment of enterprises to the declared priorities of sustainable development. Such ratings are already included in the professional toolbox of most investors. However, the ESG-ratings market is currently in its infancy stage and is relatively immature with a number of characteristic problems inherent in it. Based on the analysis of Russian and foreign scientific literature and analytical reports of consulting companies, the key problems hindering the development of this market, limiting the practical potential of using ESG ratings and undermining the trust of customers and users to these ratings have been identified. The analysis of the correlation between ratings calculated by various providers with consideration of methodological factors that predetermine discrepancies between ratings at the fundamental level is carried out. The review of the current state of the Russian ESG-ratings market is made taking into account current geopolitical challenges and the latest regulatory initiatives proposed by the Bank of Russia
Radon Daughter Ion Implantation in the nEXO Cathode
Authors:   , Chambers Evan Thomas , Dolinski Michelle J
Published: October 2023

The search for neutrinoless double-beta decay, a theoretical particle decay process in which a nucleus undergoes two simultaneous beta decays without emitting any neutrinos, is a field on the cutting edge of neutrino physics because of this type of decay's potential to expand our knowledge beyond the standard model. nEXO will be a next-generation neutrinoless double-beta decay detector with a lifetime sensitivity on the order of 10²⁸years. An important task in detecting neutrinoless double-beta decay is mitigating background radiation, particularly from radioactive impurities within the detector. An important class of radioactive impurities are radon-222 and its decay daughters. Radon daughter ions, attracted to the negatively-charged cathode, have a chance to embed themselves into the cathode material due to nuclear recoil. This ion implantation presents a more complicated problem in modelling the effect of these radon daughters on radioactive background. As demonstrated in this thesis, ion implantation is significant enough of a factor in how background radiation will be detected in nEXO that this phenomenon must be carefully studied in the detector design.

Authors: Huang Tao
Published: October 2023

With the gradual deterioration of today's ecological environment, there is an urgent need to improve the quality of environmental education. The current environmental education has grown somewhat with the increase in government investment. However older teaching methods seem inadequate to deal with the current situation. The integration of music teaching into environmental education, as explored in this paper, can be a good solution to this problem. This fun and educational approach is a good way to enhance students' interest in learning. After the corresponding discussion on the value of integration, the article used hierarchical analysis to conduct a fuzzy comprehensive evaluation of the combined utility. After stratifying the corresponding influencing factors, the weights were assigned and satisfactory evaluation results were obtained. An example was used for the analysis in this paper. The results showed that third graders with appropriate education got a significant improvement in their scores than sixth graders with no education. Both their median and mean scores improved from 66 and 60 to 70, respectively. More students are also concentrated in the high-score segment. In terms of the direction of focus, the percentages of the four areas of saving food, saving water, saving electricity, and separating garbage all changed. The values of the corresponding numbers for the third and sixth grades are 29%, 20%, 23%, 28% and 29%, 15%, 21%, 35%, respectively.

Aim    To evaluate the incidence of iron deficiency (ID) in men and women with chronic heart failure (CHF) and to compare clinical and functional indexes in patient with and without ID depending on the gender.Material and methods    An additional analysis of the study “Prevalence of Iron Deficiency in Patients With Chronic Heart Failure in the Russian Federation (ID-CHF-RF)” was performed. The study included 498 (198 women, 300 men) patients with CHF, in whom, in addition to iron metabolism, the quality of life and exercise tolerance (ET) were studied. 97 % of patients were enrolled during their stay in a hospital. ID was defined in consistency with the European Society of Cardiology (ESC) Guidelines. Also, and additional analysis was performed according to ID criteria validated by the morphological picture of the bone marrow.Results    ID was detected in 174 (87.9 %) women and 239 (79.8 %) men (p=0.028) according to the ESC criteria, and in 154 (77.8 %) women and 217 (72.3 %) men (p=0.208) according to the criteria validated by the morphological picture of the bone marrow. Men with ID were older and had more severe CHF. They more frequently had HF functional class (FC) III and IV (63.4 % vs. 43.3 % in men without ID); higher concentrations of N-terminal pro-brain natriuretic peptide (NT-proBNP) and lower ET. HF FC III increased the probability of ID presence 3.4 times (p=0.02) and the probability of HF FC IV 13.7 times (p=0.003). This clinical picture was characteristic of men when either method of determining ID was used. In women, ID was not associated with more severe CHF.Conclusion    Based on the presented analysis, it is possible to characterize the male and female ID phenotypes. The male ID phenotype is associated with more severe CHF, low ET, and poor quality of life. In females of the study cohort, ID was not associated with either the severity of CHF or with ET.

Published: October 2023

La dimensión crítica en su vinculación al área de Lengua Castellana y Literatura es uno de los grandes retos educativos del momento. Por esta razón, se plantea como objetivo principal evaluar la capacidad que poseen los estudiantes de Educación Primaria para responder a temáticas controvertidas presentadas a través de la literatura infantil. Los objetivos específicos derivan de las variables del estudio, las cuales se basan en las características de los centros participantes y tienen la finalidad de analizar posibles diferencias en cuanto a su pertenencia al programa Centros Digitales y su ubicación urbana o rural. En consecuencia, se analizaron 1191 producciones creadas por estudiantes de cuarto, quinto y sexto curso de Educación Primaria. El alumnado realizó las composiciones escritas a través de un pretexto de literatura infantil que trataba una cuestión socialmente viva, concretamente el abuso tecnológico. Dicho análisis se basa en un paradigma cualitativo, el cual se enfocó con el programa informático Atlas.ti mediante la asociación de categorías. Los resultados han permitido detectar que esta capacidad crítica no se encuentra arraigada entre los estudiantes de Educación Primaria, por lo que la literatura infantil se sitúa como un elemento esencial para potenciar el tratamiento de problemas socialmente relevantes.
A Study on the Issue of‘Relationship with Authentic Context’in Learning Experience: Interpretation o

This study had a goal to discuss the transfer, which is related with real life, based on situated learning theory. Situated learning theory is known to have provided a new theoretical basis for the design of teaching and learning based on learning through interaction and contextuality of learning, which had been overlooked so far. Since situated learning theory also has a discussion of situativity and contextuality, it is expected that the results derived from situated learning theory would broaden the horizon of understanding of 'learning linked to life'. And In this study, by examining situational learning theory suggested the transfer can happen better by practicing the gap between the context of the outside world and their own context than discovering similarity of problems had and while learners have practiced to negotiate the context between problem and themselves. Considering the research of situated learning theory, education for transfer that linked life goes beyond the meaning of real context to the need for educational design that leads inquiry’s context. It is hoped that this study contributed to interpretation of situational learning theory, and can provide implications for teaching and learning design in the educational field to translate “real life”
Comparison of fatigue behaviour and fracture toughness of cobalt chromium alloy fabricated by casting and selective laser melting methods

Co-Cr alloys are most commonly used base metal alloy in dentistry for the fabrication of many types of metallic substructures. They gained popularity due to their good mechanical properties and low cost. There are different techniques for fabrication of Co-Cr alloys which includes casting and DMLS technique. However, change in the fabrication techniques showed variation in mechanical properties.

Forty Co-Cr samples each were made from two different techniques, Casting and DMLS. Fracture toughness was done with charpy’s impact test machine and fatigue behaviour test was done with nano universal testing machine. The samples were later observed under stereo electron microscope to assess the kind of failure.

Unpaired t test revealed that there was statistically significant difference between two different groups. The mean difference of fracture toughness in Casting group was higher when compared with DMLS group. The number of fatigue cycles were higher in DMLS group than the casting group.

Within the limitations of this in vitro study, casting group showed higher fracture toughness when compared to DMLS group, whereas fatigue limit was higher in DMLS group than casting group.

Irritable bowel syndrome (IBS) is functional bowel disorder characterized by abdominal pain or discomfort and altered bowel habits in the absence of detectable structural abnormalities. Protozoan cysts are commonly found in the stool samples of patients with IBS and a rising body of evidence suggests a direct causal relationship. Cryptosporidium infection can be a potential candidate for IBS. We studied prevalence, association, and genotype of cryptosporidium at a tertiary care centre.

Using a case-control design, a total of 100 cases and 100 controls were selected between 2016 and 2017. Fresh stool samples were collected and processed for microscopic examination. Positive samples were subjected to PCR RFLP for speciation and results analysed for Odd’s ratio, relative risk and relationship between variables.

There was a high male preponderance (m: f=9:1). Most patients belonged to the middle age group (34.8-42.4 years). Amongst the clinical subtype IBS with diarrhoea (IBS-D) was the most common subtype (63%). Odd’s ratio for having IBS was 57.5 with cryptosporidium with a relative risk of 2.09. Adjusted Odd’s ratio for age was 1.014 suggesting a linear correlation (r value=0.07) with age.

Our study shows a significant risk of developing IBS with cryptosporidium infection. The authors recommend studies with larger population samples both within the northern regions of India and across the country to determine prevalence, speciation of cryptosporidium and its relationship to IBS.

Conflict and poverty have forced millions of people in Latin America and the Caribbean to leave their homes and migrate to other countries without legal protection. This study identifies the challenges faced by migrants in Chile, Ecuador, and Peru in their attempt to access basic services and other benefits that, in many cases, require them to have specific documentation, including legally recognized identity credentials. A qualitative approach is applied using interviews to document the experiences of 16 migrants and refugees with different characteristics, such as age, gender, sexual orientation, country of origin, and physical abilities. This research provides evidence on how these refugees and migrants struggle to integrate into their host countries as well as recommendations based on their most pressing challenges when trying to access services and obtain documents. As a result, this document highlights that evolving legislation, a lack of information, and siloed government departments are among the key factors that influence the experiences of migrants and refugees in these countries.
