Amniotic Fluid Embolism
Authors: Jain Divyanu
Published: May 2023

Amniotic fluid embolism (AFE) is a rare yet devastating complication of pregnancy. The outcomes are often poor, proving fatal for both mother and neonate. The incidence and mortality rate due to AFE is quite high even in developed countries and may be much higher in developing countries. Data from developing countries are unavailable. There is no uniform internationally accepted diagnostic criterion for AFE. No single diagnostic test has been found sufficient to suspect AFE in the early stages. Recently, complement system activation and an anaphylactoid reaction in the uterine tissue have been proposed in relation to its pathophysiology. In few cases, the use of complement C1 inhibitor with tranexamic acid, atropine, ondansetron, ketorolac therapy, and extracorporeal membrane oxygenation was observed to be very effective for early management. The studies on the pathophysiology of AFE are still limited. Further research is required to know the mechanism of this disease. Reliable rapid diagnostic tests are much needed at this stage. It is important to investigate the histopathology of tissues affected by AFE and find the origin of the disease in the maternal system. This review intends to highlight the best known and the unknown aspects of AFE relevant for future research purposes to minimize the fatality/mortality rate due to AFE, which remains an undiagnosed cause.

Authors: Khalaf Asmaa R. , Foad Amira M. , Hemdan Shimaa B. , Nabil Emad E. , Esmaeel Hend M.
Published: May 2023

Background

Lung cancer is known as one of the commonest cancers globally. It is considered an important cause of mortality all over the world. Survivin, a member of the family of inhibitor of apoptosis proteins, is involved in cell division regulation and apoptosis inhibition. The survivin gene is located on the human chromosome 17q25 and consists of 142 amino acids. Cancer risk was shown to be affected by the survivin promoter −31G/C genetic polymorphism. Such genetic variance was found to be associated with aberrant survivin expression in malignant cell at both protein and mRNA levels. One of the tumor suppressor gene is the p53 protein that induces cell apoptosis. Therefore, survivin polymorphism and p53 antibodies level association was considered in non-small-cell lung cancer (NSCLC).

Aim

To assess survivin promoter −31G/C polymorphisms in NSCLC, with detection of p53 antibodies level and the association between it and the gene polymorphism in those patients.

Patients and methods

In 2019–2020, a case–control designed research work was performed at Sohag University Hospital, Egypt. A total of 60 study participants were included in our study and categorized into 15 control group and 45 histopathologically confirmed NSCLC case group. The blood samples were collected into an EDTA tube and preserved frozen till DNA extraction.

Results

Our study shows a highly significant variation in the prevalence of the surviving gene promoter −31G/C polymorphism between cases and control groups (P<0.001). Moreover, regarding the level of p53 antibodies, it was higher in cases (17.01±5.97) than the control group (45.9±46.01), but the difference was not statistically significant (P=0.59). In our study, survivin −31G/C polymorphism was accompanied by epidermal growth factor receptor mutations detected in 33.3% of the cases, whereas 66.7% of the cases showed no mutation (wild type) of epidermal growth factor receptor.

Conclusion

Survivin promoter −31G/C gene polymorphism might have an association with lung cancer risk.

Authors: Elkholy Maha M. , Sadek Samiaa H. , Elmorshedy Reham M. , Abdulmoez Marwa S.
Published: May 2023

Background

Extubation failure is defined as the need for reinstitution of artificial airway within 48–72 h after planned extubation. It is associated with prolonged ICU and hospital stay and is more liable to serious complications and mortality.

Objectives

To evaluate the frequency of incidence and predictors of extubation failure in mechanically ventilated patients with chronic obstructive pulmonary disease (COPD) and its effect on their outcome.

Patients and methods

This observational descriptive cross-sectional study was carried out on 150 mechanically ventilated patients with COPD. All patients were assessed regarding the severity of the disease using both acute physiology and chronic health evaluation (APACHE) II and simplified acute physiology score scores and cough strength by white card test, with assessment of the amount of the secretion. All ventilatory parameters were monitored, with more attention given to the following: rapid shallow breathing index, negative inspiratory force (NIF), airway occlusion pressure, and weaning indices. Duration of sedation, complications, length of ICU stay, and also mortality rate were recorded.

Results

According to outcome of extubation, patients were classified into two basic groups: successfully extubated and failed extubation. Extubation failure occurred in 14.7% of the studied patients. Independent predictors of extubation failure were APACHE II more than 26, NIF less than −19, negative white card, CROP less than 11.5, large amount of secretions, and need for sedation more than 2 days. There were significant increases in the incidence of ventilator-associated pneumonia, mortality, ICU, and hospital stay among reintubated group.

Conclusion

APACHE II more than 26, NIF less than −19, negative white card, CROP less than 11.5, large amount of secretions, and need for sedation more than 2 days are good predictors of extubation failure in patients with COPD. Extubation failure is associated with more frequent morbidity and mortality.

Published: May 2023

Background

Lung cancer mortality is high all over the globe. A total of three million deaths are expected to be reached in 2035. There is a rising effort nationally for cancer data documentation and networking. This study is in line with this effort.

Purpose

This study aimed at assessment of the survival of patients with lung cancer in the regional locality and assessing factors affecting mortality in the studied population.

Patients and methods

This retrospective study included patients with lung cancer who were diagnosed and received treatment in the Oncology Department, Sohag University Hospital and Sohag Oncology Institute during the period from January 2016 to June 2019. The available data in patients’ records were collected, and it included medical history, clinical finding, diagnostic and metastatic workup, treatment, and follow-up for outcome.

Results

A total of 160 patients were enrolled in this study. Their median survival time was 1.21 year. Nonsmall-cell lung carcinoma, squamous subtype, showed higher 3-year survival (35.67%) than other histopathological subtype. Earlier tumor stage, stage II B, showed better survival than more advanced stages. Presence of positive local signs, current smoking status, and poorly differentiated tumor were significant risk factors for mortality in final multivariate analysis.

Conclusion

The study documented bad prognosis of lung cancer in our regional locality. It emphasized the worse prognosis for advanced stage of tumor and confirmed the role of smoking not only in development of lung cancer but also as mortality risk factor, which highlights the importance of smoking cessation programs to be initiated with focus on public awareness about it.
BRCA mutations
Authors: Talwar Vineet , Rauthan Amit
Published: May 2023

Ovarian cancer (OC) is one of the most lethal gynecological cancers with a 5-year survival rate that ranges from 30% to 40%. Breast cancer genes (BRCA1 and BRCA2) play a key role in maintaining genomic stability. Mutations in BRCA1/2 genes lead to the accumulation of double-strand breaks, resulting in tumorigenesis. The risk of developing OC in women with BRCA1 and BRCA2 mutations is 39% and 11%, respectively, by 70 years of age. BRCA1/2 mutation testing is thus important to identify women at greatest risk of developing OC in addition to its impact on diagnosis, prognosis, and targeted therapy. Genetic testing is required to identify the BRCA mutations and thus select patients who can benefit from polyadenosine diphosphate (ADP)–ribose polymerase (PARP) inhibitor therapy. Tumor BRCA mutation testing can detect both germline and somatic mutations allowing implementation of preventive strategies on a broader population. Various international guidelines recommend BRCA1/2 mutation genetic testing in all OC patients irrespective of age and family history. This review focuses on the role of BRCA mutation testing in OC.
Placental expression of striatin & endothelial nitric oxide synthase in women with & without pre-eclampsia
Authors: Viveka M , Chaturvedula Latha , Ram Amit Kumar , Vairappan Balasubramaniyan
Published: May 2023

Background & objectives:

Striatin is a multi-domain scaffolding protein essential for activating endothelial nitric oxide synthase (eNOS). However, its role in pre-eclampsia remains use explored. Hence, this study aimed to investigate the association between striatin and eNOS in regulating nitric oxide (NO) production in the placenta of women with and without pre-eclampsia.

Methods:

Forty pregnant women each without (controls) and with pre-eclampsia (cases) were enrolled in the study. Blood striatin and NO concentrations were detected by the ELISA. Protein expression of striatin, phosphorylated eNOS (peNOS), inducible NOS (iNOS) and phosphorylated NF-κB were measured in the placental tissues by Western blot. Twenty four hour urinary protein and serum urea, uric acid and creatinine were analyzed as an autoanalyzer. Placental histology was analyzed by haematoxylin and eosin staining.

Results:

Compared to normotensive pregnant women, the levels of serum NO and striatin were decreased in pre-eclamptic women. The protein expression of striatin and peNOS was significantly reduced (P<0.05) while p65NF-κB and iNOS were upregulated considerably (P<0.05) in the placenta of cases compared to controls.

Interpretation & conclusions:

Our results show for the first time that decreased striatin expression was associated with decreased peNOS protein expression in the placental tissue of pre-eclamptic women. Interestingly, no significant difference was found in blood striatin or NO levels between controls and cases. Thus, therapies that improve placental striatin expression are attractive possibilities, both for prevention as well as treatment of endothelial dysfunction in pre-eclampsia.
“Lockdown Was a Blessing in Disguise for Me as it Stopped Me Gambling” – First Person Account of a Lottery Addict from God's Own Country (Kerala, India)
Authors: George Sanju , Fenn Jessy , Chacko Noble
Published: May 2023

Playing the lottery is the only legal form of gambling in Kerala and it is hugely popular. The Government of Kerala, which exclusively runs the sale of lotteries in the State, abruptly stopped its sale for two months as part of the National lock down. Here, we discuss how the lock down helped a lottery addict use this lock down period as a window of opportunity to seek help and escape from his gambling addiction. There are wider public health lessons to be learnt about how this approach might be utilised to address other substance addictions.
Do We Really Understand Addictions to Internet Well Enough to be able to Manage it in the Young Population
Authors: Srivastava Chhitij
Published: May 2023

Behavior addictions, including those to internet and smartphones, stem largely from underlying vulnerabilities. This article describes a framework that takes into consideration these vulnerabilities, the environmental conditions that contribute to addictions, the actual addiction and the secondary effects of addictions. In the author's view, this framework can be used to help come up with a comprehensive and individualized formulation when assessing behavior addictions in the young population thereby helping in tailored management. Some important underlying vulnerabilities include symptoms of attention deficit hyperactivity disorders, anxiety, depression, and trait impulsivity. The modifying effects of the environment on these vulnerabilities need to be understood comprehensively, especially those relating to parenting, schooling, and secondary effects of psychiatric problems in family members. The content of the actual addiction has to be properly understood as it can include a variety of different things such as gaming, social media, shopping, and gambling. Addiction processes including impulsive-compulsive phenomena, withdrawal, and craving have to be factored in the management plan. The secondary effects of addictions including the physical, psychiatric, and those related to exploitation of these children also need to be addressed systematically. The formulation and management plan therefore can possibly include a number of psychiatric disorders, temperamental traits, environmental conditions, and various secondary health aspects of the addiction. The goals of managing behavior addictions related to internet and smartphone usage are predominantly about harm reduction as our lives have become increasingly dependent on the benefits of this smart technology.
Vision for Total Care of Persons with Developmental Disabilities
Authors: Murthy R. Srinivasa , Divya B. , Nischitha S.
Published: May 2023

During the last 75 years of Independent India, there has been significant progress in the care and recognition of the rights of persons with disabilities (PwDs). The setting up of the National Institute for Mentally Handicapped in 1984, Rehabilitation Council in 1992, the National Trust in 1999, the revision of the legislation covering the rights of the PwDs in 2016 are all indicative of the recognition of the rights of persons living with developmental disabilities and their caregivers. However, in spite of the articulation of a need for a National Plan, over four decades back, there is much that needs to be addressed. The most recent program to disseminate from village level to national level, the rights of persons with disability is a positive step. There is an urgent need to initiate pilot programs in geographically limited areas to develop care programs from birth to the end of life. This article presents a comprehensive vision for the future with the hope this will find support from the public, professionals, and policymakers.
Impact of Lockdown and Psychological First Aid
Authors: Varma Ruchi , Yannawar Pravin B , Antony Reshma
Published: May 2023

Introduction:

The COVID-19 pandemic and the subsequent lockdown declared by the Indian Government in March 2020 lead to an unexpected turn of events for many, causing a huge psychosocial impact on them.

Methodology:

The study focused on evaluating a family from Kerala with major language difficulties and the distress being faced by them during their stay in the government provided shelter home in Delhi. The family was assessed by the multidisciplinary team from the Institute of Human Behavior and Allied Sciences visiting various shelter homes across the state. The study was aimed to assess the importance of psychological first aid (PFA) on the individual and the family in distress.

Results:

The family was assessed by the student counselor, who was well versed in their native language Malayalam. They were able to connect well, and hence, an appropriate psychosocial intervention was provided to them under the guidance of her supervisor. The family was highly distressed and had almost developed xenophobia. They were very happy to get a Malayalam-speaking counselor and were provided with all possible support. The authorities were also explained about their specific needs, which was not possible earlier due to the language barrier. They were ultimately successfully integrated with the other residents and returned to their home state, i.e., Kerala.

Conclusion:

Although PFA is definitely not a substitute for mental health care, ample research and experience has shown that it is a useful tool to assist people in acute distress when applied with a truly professional yet sensitive, empathetic approach.
Complete quadrics: Schubert calculus for Gaussian models and semidefinite programming
Authors: Manivel Laurent , Michałek Mateusz , Monin Leonid , Seynnaeve Tim , Vodička Martin
Published: May 2023

We establish connections between the maximum likelihood degree (ML-degree) for linear concentration models, the algebraic degree of semidefinite programming (SDP), and Schubert calculus for complete quadrics. We prove a conjecture by Sturmfels and Uhler on the polynomiality of the ML-degree. We also prove a conjecture by Nie, Ranestad and Sturmfels providing an explicit formula for the degree of SDP. The interactions between the three fields shed new light on the asymptotic behaviour of enumerative invariants for the variety of complete quadrics. We also extend these results to spaces of general matrices and of skew-symmetric matrices.

Introducción. Se analiza el impacto de los contenidos publicados sobre Banksy en los principales diarios generalistas. Se trata de detectar el tratamiento que hace la prensa española sobre esta figura. Determinar si se publica contenido en la misma proporción, cuál es la temática principal o si existen connotaciones evaluativas. Metodología. Algunas hipótesis apuntan a que Banksy consigue poner el foco mediático en las causas sociales que reivindica y que los medios más conservadores le dedican un espacio más limitado y crítico. Se analizan las publicaciones que contienen la palabra Banksy durante un período de repercusión, mediante una ficha elaborada ad hoc para este estudio. Se registran un total de 2248 items, de 221 piezas analizadas. Resultados. El diario ABC es donde en mayor proporción aflora el carácter evaluativo negativo, pero también el que más espacio le dedica Banksy o a su obra, seguido de El País. La causa reivindicada por Banksy es escasamente tratada por todos los diarios, siendo nula en el caso de El Mundo. Conclusiones. Se constata que un diario conservador como ABC no necesariamente limita su espacio a este tipo de contenidos a priori vinculados a reivindicaciones sociales. Sin embargo, el debate sobre el valor de su obra y la propia figura de Banksy, altamente adjetivada en general, cobran protagonismo frente a las causas sociales que reivindica. Se constata el carácter icónico de Banksy, incluso como concepto, que es empleado por los diarios como una marca, hasta en los contenidos que no se refieren directamente a él.

Industry groups in international governance: a framework for reform
Authors: Durkee Melissa J
Published: May 2023

The Sustainable Development Goals and the UN Guiding Principles on Business and Human Rights encourage engaging with businesses as partners in important global governance agendas. Indeed, many international organizations are now partnering with business groups to secure funding and private sector engagement. At the same time, reforms at the World Health Organization, Food and Agriculture Organization and others seek to restrain the dangers of mission distortion and capture by business groups. Shareholders at major multinational oil and gas companies also recognize these dangers and seek to rein in lobbying that is at odds with the goals of the Paris Climate Agreement. Despite these tensions, little scholarly attention has been paid to the regulations that govern how industry and trade groups may participate in the work of international organizations. Specifically, little attention has been devoted to how those regulations could best capture the potential benefits of business engagement while restraining the potential harms. This article offers a history of engagement between international organizations and industry and trade associations, reviews arguments for embracing or restraining their participation, and develops a framework for regulations to govern their access.
A new discrete theory of pseudoconvexity
Authors: Keszegh Balázs
Published: May 2023

Recently geometric hypergraphs that can be defined by intersections of
pseudohalfplanes with a finite point set were defined in a purely combinatorial
way. This led to extensions of earlier results about points and halfplanes to
pseudohalfplanes, including polychromatic colorings and discrete Helly-type
theorems about pseudohalfplanes.
Here we continue this line of research and introduce the notion of convex
sets of such pseudohalfplane hypergraphs. In this context we prove several
results corresponding to classical results about convexity, namely Helly's
Theorem, Carath\'eodory's Theorem, Kirchberger's Theorem, Separation Theorem,
Radon's Theorem and the Cup-Cap Theorem. These results imply the respective
results about pseudoconvex sets in the plane defined using pseudohalfplanes.
It turns out that most of our results can be also proved using oriented
matroids and topological affine planes (TAPs) but our approach is different
from both of them. Compared to oriented matroids, our theory is based on a
linear ordering of the vertex set which makes our definitions and proofs quite
different and perhaps more elementary. Compared to TAPs, which are continuous
objects, our proofs are purely combinatorial and again quite different in
flavor. Altogether, we believe that our new approach can further our
understanding of these fundamental convexity results.
Regional Development through the Lens of Geographical Indications in Northeast Brazil
Authors: Silva André Almeida , Silva Gabriel Francisco da
Published: May 2023

Regional development is directly linked to the historical evolution of communities and the occupation of their territories, as well as the current state of the occupied or explored spaces, and their economic dynamics. In this sense, knowing that discussions on regional development are crucial, one should note that geographical indications (GIs) can contribute to its achievement. Therefore, this paper aims at investigating the relations between geographical indications and the regional development of Brazil’s Northeast, seeking to understand if there has been any relevant development in the region since the granting of GIs. By adopting a qualitative and quantitative approach, including bibliographic study, documentary analysis, and data survey through questionnaires applied to representatives of the 16 current geographical indications in the Northeast, we observed that there was, in fact, regional development after the certification of these GIs, especially concerning the valorization of manufacturers, products, and locations. However, it was also evident that there is a need for restructuring, mainly of the GIs that are not using the stamp. It is of the utmost importance to establish a partnership between public and private institutions, associations, and manufacturers to strengthen and integrate the actors of different production chains, generating a kind of development guided by the balance between economic, environmental, social, and cultural benefits.
ADAPTIVE COAL CLASSIFICATION USING DEEP LEARNING
Authors: D.Mohanapriya  , N.Nafreen Banu  , K.Vannamathi  , L.Sharnitha shri
Published: May 2023

Coal classification is an essential process in the mining industry, which involves identifying the quality and type of coal extracted from the earth. Traditional methods of coal classification rely on manual inspection and analysis, which can be time-consuming and prone to errors. With the advent of machine learning techniques, it is now possible to automate this process and achieve higher accuracy and speed in coal classification. The first effort in learning about coal is observing coal features. This project developed a coal search system that allows users to do a search even when they do not know the coal name simply by observing coal characteristics. At present, coal classification uses machine vision to extract and analyze color, size, shape, and surface texture. Still, the new extraction margin method can be carried out roughly yet there is still a difference between the margin of extracted polygon, shape and the margin of the shape of original image. The project aims in finding the gangue in the coal. Total gangue percent in the coal data is then calculated and displayed which is based on pixels count of gangue colors. This assists in evaluating the coal quality. If future researchers were to expand to other features, coal gangue, etc., even those that are hard to quantify, can also be quantified. Artificial Neural Network is used for classifying the coal dataset. The project is designed using Python as frontend environment. The coding language used is the Python 3.7.

Published: May 2023

Ornamental vegetable gardens have many benefits. They are aesthetic, educational, ecological, economical, sanitary, and are a source of fresh food. Small allotments in urban and peri-urban areas do not allow the implementation of utilitarian gardens. Thus, ornamental vegetable gardens are the best choice. Raised beds can be used to enhance the decorative effect of the entire vegetable garden. This type of construction presents, in turn, several advantages both for the user and crop: reduced effort for maintenance work, early heating of the substrate, loose substrate, reduced volume of weeds, efficient use of space for plants, etc. Establishing ornamental vegetable gardens on raised beds is easily achieved using geometric modules, as they can be adapted to various designs. This paper presents several design options for a decorative vegetable garden on private properties. The case studies presented showed different methods of using modular raised beds depending on the property's area, the owner's wishes, and the desired area to be planted. Also, depending on the results obtained from the experimental batch, three other variations of modular layouts with different purposes were proposed: focal point, physically closed but visually open space, and relaxation space.

In the world of education, there are many elements that can affect the achievement of learning outcomes, including elements of teachers, students, curriculum and facilities and infrastructure that can support learning. Currently, there are still many students in learning who have not found the answer on their own because they are not given the opportunity to practice by the teacher, thus making students feel bored and more passive. Currently, there are still many schools whose students are only given memorization about concepts and not understanding and mastering concepts in terms of solving a problem plus the support of teachers who are less creative in using media in the learning process which makes it increasingly difficult for students to understand the material. Learning methods that take place effectively and efficiently and can be done anytime, anywhere, using any path and with any access speed can be done with the E-learning method. The E-learning method, apart from being able to provide teaching materials and instruction in learning that can be accessed anytime and anywhere, also does not require a large room like a conventional room. In the teaching and learning process there are several problems that arise, namely the problem of limited learning time at AD-DA'WAH Vocational School, the lack of interaction between teachers and teachers outside school hours, limitations between classrooms and the number of students who are not commensurate, which makes the learning process less efficiency. These problems will be solved by designing a learning application with e-learning, which is proven to be efficient in solving problems such as those that occur in the teaching and learning process. The results showed that the e-learning method succeeded in increasing positive efficiency when applied to solve problems.

Face non-spoofing detection is an important job used to ensure authentication security by performing an analysis of the captured faces. Face spoofing is the process of fake faces by other people to gain illegal access to the biometric system which can be done by displaying videos or images of someone's face on the monitor screen or using printed images. There are various forms of attacks that can be carried out on the face authentication system in the form of face sketches, face photos, face videos and 3D face masks. Such attacks can occur because photos and videos of faces from users of the facial authentication system are very easy to obtain via the internet or cameras. To solve this problem, in this research proposes a non-spoofing face detection model on video using Faster R-CNN. The results obtained in this study are the Faster R-CNN model that can detect non-spoof and spoof face in real time using the Raspberry Pi as a camera with a frame rate of 1 fps.
