A new attribute-linked residential property price dataset for England and Wales, 2011–2019
Authors: Chi Bin , Dennett Adam , Oléron-Evans Thomas , Morphet Robin
Published: May 2021

Current research on residential house price variation in the UK is limited by the lack of an open and comprehensive house price database that contains both transaction price alongside dwelling attributes such as size. This research outlines one approach which addresses this deficiency in England and Wales through combining transaction information from the official open Land Registry Price Paid Data (LR-PPD) and property size information from the official open Domestic Energy Performance Certificates (EPCs). A four-stage data linkage is created to generate a new linked dataset, representing 79% of the full market sales in the LR-PPD. This new linked dataset offers greater flexibility for the exploration of house price (£/m2) variation in England and Wales at different scales over postcode units between 2011 and 2019. Open access linkage codes will allow for future updates beyond 2019.
Rechte Gefühle
Authors: Strick Simon
Published: May 2021

Dem Faschismus geht es gut - er ist Meme, Konsumgut und Gefühlswelt geworden. Seine Gewaltträume und Männerphantasien finden im Netz ein perfektes Biotop. Rechte Agitator*innen schaffen marktfähige Gefühlsmuster, die von YouTube und den Parlamenten bis auf die Straße reichen. Sie bauen anziehende Gegenrealitäten - und gewinnen damit Wahlen, Follower und Publikum. Von GamerGate bis Halle, »großer Austausch« bis »Corona-Lüge« - Simon Strick untersucht die affektiven Strategien rechter Akteur*innen. Zahlreiche Analysen zeigen, wie sie Gefährdungsgefühle für Weiße und Männer populär und anschlussfähig machen: Dieser Faschismus spricht die Sprache der Risikogesellschaft und manipuliert effektiv demokratische Öffentlichkeiten. Distanzierung ist kein Mittel gegen diese rechte Gefühlsrevolution. Auf Rechte Gefühle muss kollektiv und affektiv geantwortet werden.
Häusliche Pflege am Limit
Authors: Münch Anne
Published: May 2021

Demenz zählt zu den zentralen Herausforderungen der gegenwärtigen Gesellschaft des langen Lebens. Dabei ist nicht nur der Umgang mit der Diagnose von Relevanz, sondern insbesondere auch die Pflege der Betroffenen. Diese wird in Deutschland mehrheitlich von Angehörigen übernommen. Anne Münch lässt in ihrer empirisch geleiteten Studie die Angehörigen selbst zu Wort kommen und liefert einen differenzierten Einblick in ihre Lebenssituation. Mit Analysen zur Bedeutung von Raum, Zeit, Geschlecht und den dabei stetig neu auszuhandelnden Grenzen leistet sie einen wichtigen Beitrag dazu, den Pflegenden eine Stimme zu geben und die Bedingungen in der häuslichen Pflege sichtbar zu machen.
Regulating Transitions from School to Work
Authors: Dahmen Stephan
Published: May 2021

How are activation programs for the young unemployed implemented? How do street-level bureaucrats deal with competing rationalities and demands for action? Transition policies increasingly aim at promoting self-regulation and constructing employable subjects. Stephan Dahmen explores the practical regulation of biographical transitions in activation programs for the young unemployed by focusing on the interactive accomplishment of activation work. The study reveals how the critical tensions of activation policies are continually re-interpreted and adapted to local contingencies and describes the various organisational technologies used for creating employable subjects.

Published: May 2021

Wie fühlt es sich an, als Sicherheitsproblem wahrgenommen zu werden? Wie wirkt sich das auf das Leben von »Muslim:innen« aus? Wie gehen sie in ihrem Alltag, ihren Beziehungen und bei ihrer Arbeit damit um? In Einzelinterviews und Gruppendiskussionen sprechen muslimische Akteur:innen darüber, wie sie angesichts des Sicherheitsdiskurses ihre Deutungs- und Handlungsmacht (wieder) gewinnen. Dabei wird rekonstruiert, wie Muslim:innen (oder als solche Markierte) das Verhältnis von Zustimmung und Kritik angesichts ihrer Adressierung austarieren und wie es ihnen gelingt, ihre Diskursivierung nicht (gänzlich) anderen zu überlassen und ihre Interessen umzusetzen.
Berührbarkeit als conditio humana
Authors: Hecker Héla
Published: May 2021

Hannah Arendts leidenschaftliches Denken offenbart sich in ihrem Werk u.a. durch die häufige Nennung emotionaler Phänomene wie Wut, Liebe, Mut oder Mitleid. Bislang wurde diese affektive Argumentationsebene jedoch nicht systematisch untersucht. Héla Hecker argumentiert dafür, dass Arendt Gefühle und Affekte nicht als per se apolitisch, sondern als welteröffnende bzw. -verschließende Artikulationen einer grundsätzlich menschlichen Berührbarkeit bewertet. Das Politische ist der Bereich, in dem diese Berührbarkeit als conditio humana frei und geschützt gelebt werden kann. Gleichzeitig bürgt die Fähigkeit, sich vom Anderen und von der Welt berühren zu lassen, für die Möglichkeit von Freiheit und Neubeginn.
Evaluation of four point cloud similarity measures for the use in autonomous driving
Authors: Berens Felix , Elser Stefan , Reischl Markus
Published: May 2021

Measuring the similarity between point clouds is required in many areas. In autonomous driving, point clouds for 3D perception are estimated from camera images but these estimations are error-prone. Furthermore, there is a lack of measures for quality quantification using ground truth. In this paper, we derive conditions point cloud comparisons need to fulfill and accordingly evaluate the Chamfer distance, a lower bound of the Gromov Wasserstein metric, and the ratio measure. We show that the ratio measure is not affected by erroneous points and therefore introduce the new measure “average ratio”. All measures are evaluated and compared using exemplary point clouds. We discuss characteristics, advantages and drawbacks with respect to interpretability, noise resistance, environmental representation, and computation.

Seasonal color matching method of ornamental plants in urban landscape construction
Authors: Wang Dayan
Published: May 2021

Traditional seasonal color matching methods of ornamental plants only study the color attributes of plants, but not through qualitative and quantitative research on seasonal color matching of plants, resulting in imperfect matching methods. Five landscape units were selected from five representative streets in Harbin, namely, Central Avenue, Gogoli, Zhongshan Road, Xinyang Road, and Huanghe Road. Seasonal periods of Harbin from 2014 to 2018 were defined using the difference in seasonal time division and duration characteristics by the method of climate temperature division, and the beginning time of each season in 2019 was deduced. Meanwhile, according to the NCS color value data of each species in different seasons and the length of each season, the seasonal color matching results of each landscape unit case were established. The results of seasonal color matching of each landscape unit case were evaluated by weighted method. The results showed that the richer the NCS color value of plant species ornamental traits in plant landscape, the more the color seasonal encounter of ornamental traits and the longer the duration, the better the matching results of plant seasonal color. Based on the research results, the NCS color value and its ornamental period of ornamental characters of plant species, the color matching scheme of landscape color, and the selection of plant species were proposed.

Some Observations on the Study of the History of Cultural Interactions in East Asia
Authors: Huang Chun-chieh
Published: May 2021

This paper attempts to incorporate the history of East Asian cultural interactions into the field of regional history, and toward that end proposes that certain subjects to be explored. The paper consists of five sections. Section 1 draws attention to the newer fields of regional history and global history, as distinct from national history, which occupied great academic interest in the twentieth century. Section 2 suggests a new way to study regional history: shifting our focus from the results of cultural interactions to the process, thus bringing about a paradigm shift in the study of the history of East Asian cultural interactions. Section 3 raises two problematiques in the proposed field of regional history: the mutual influence between self and other, and that between culture and the power structure. Section 4 proposes three types of exchange for further research: (1) exchanges of persons (especially professional intermediate agents), (2) exchanges of goods (especially books), and (3) exchanges of thought. The last section concludes that, with the rising of East Asian countries on the world stage in the twenty-first century, the state-centered style of historical study will be redirected to a broader East Asian perspective. By redefining the history of East Asian cultural interactions as regional history, we will be able to undertake the important task of revisiting and reconsidering on our traditional cultures.
Translating Western Concepts by Creating New Characters: A Comparison of Japanese and Chinese Attempts
Authors: Guowei Shen
Published: May 2021

Chinese characters are considered as an adaptable system, open to expansion and revision. Throughout history, the creation of new characters was one of the most important solutions to enlargements of the conceptual repertoire. Both scholars of “Dutch Learning” in Japan and missionaries active in nineteenth- century China used Chinese characters in their translations of western concepts. From a methodological point of view, Japanese scholars mostly coined compound words rendering the literal meanings of their terms of departure while translators in China, invigorated by the success of the new characters devised for chemical elements, believed that drafting new characters was more in line with the characteristics of the Chinese language. However, notwithstanding the painstaking efforts with which they were created, the new characters proposed by missionaries were eventually replaced by compound terms first used in Japanese adaptations. This paper examines the different practices and attitudes of Chinese and Japanese authors toward the creation of new characters as a method of translation. Analyzing the influence of their divergent approaches on the lexical systems of their respective languages, since Chinese has a very limited number of phonetic patterns, I conclude that it is impossible to create viable technical terminologies only by increasing new characters.
Perfect Storm: Climate Change and Tourism
Authors: Cevik Serhan , Ghazanchyan Manuk
Published: May 2021

While the world’s attention is on dealing with the COVID-19 pandemic, climate change remains a greater existential threat to vulnerable countries that are highly dependent on a weather-sensitive sector like tourism. Using a multidimensional index, this study investigates the long-term impact of climate change vulnerability on international tourism in a panel of 15 Caribbean countries over the period 1995–2017. Empirical results show that climate vulnerability already has a statistically and economically significant negative effect on international tourism revenues across the region. As extreme weather events are becoming more frequent and severe over time, our findings indicate that the Caribbean countries need to invest more in adaptation and mitigation in order to reduce vulnerabilities.
Necrosecurity, Immunosupremacy, and Survivorship in the Political Imagination of COVID-19
Authors: Lincoln Martha
Published: May 2021

The neologism ‘necrosecurity’ describes the cultural idea that mass death among less grievable subjects plays an essential role in maintaining social welfare and public order. In the early months of the novel coronavirus pandemic in the United States, this perspective on the social value of death emerged in diverse contexts, particularly in claims that deaths were a necessary consequence of returning economies to normal. Necrosecurity discourse encourages audiences to perceive coronavirus fatalities as neither preventable nor exceptional, and to perceive themselves as facing little risk of infection or death. Overlooking the realities of infectious disease epidemiology, these accounts portrayed COVID-19 as a mild disease and imagined a population of robust and physically normative individuals who would survive an epidemic unscathed and ready to return to work. These appeals articulate with powerful cultural tropes of survivorship, in which statistical calculations of relative risk and life chances—ostensibly cited to inspire hope for an individual outcome—conceal a zero-sum calculus in which ill or susceptible individuals are pitted against one another. In contrast to the construct of biosecurity—the securing of collective life against risk—necrosecurity paradoxically imagines the deaths of vulnerable others as a means of managing shared existential dangers.

Published: May 2021

This study was conducted on crude enzyme from the novel strain Acanthophysium sp. KMF001 using a mediator (surfactant). The surfactant was applied to the steam-exploded pretreated domestic wood biomass, and response surface methodology (RSM) was conducted to determine the optimum conditions for saccharification using the optimum substrate concentration, enzyme concentration, and surfactant concentration. Steam-explosion of Korean oak (25 kgf/cm2) for 7 min showed a maximum-predicted saccharification of approximately 99.9% at 7.0% substrate concentration, 37.5 FPU (filter paper units) enzyme concentration, and 475.8 mg/g-glucan surfactant (polysorbate 80) concentration. Steam-explosion of red pine (25 kgf/cm2) for 7 min revealed a maximum prediction saccharification rate of approximately 58.7% at 6.5% substrate concentration, 36.3 FPU enzyme concentration, and 330.3 mg/g-glucan surfactant (polysorbate 80) concentration. The extents of saccharification of Korean oak (99.9%) and pine (58.7%) demonstrated the high applicability of the crude enzyme from Acanthophysium sp. KMF001.

Published: May 2021

Objetivos: Verificar a associação da distância da habitação em relação a sítios de reciclagem sobre habilidades cognitivas em escolares.Métodos: Estudo transversal, no qual aplicou-se a escala Wechsler Abreviada de Inteligência em 100 escolares de 6 a 14 anos. As crianças foram divididas em um grupo de estudo (expostos), cujas residências estavam situadas a menos de 100 metros de sítios de reciclagem, em um bairro da cidade de Caxias do Sul. Houve um grupo controle, cujas residências estavam a mais de 150 metros de algum sítio de reciclagem, no mesmo bairro ou adjacências.Resultados: A habitação próxima a sítios de reciclagem aumentou a chance de apresentar quociente de inteligência baixo nos escolares na análise univariada (OR 2,19; IC95% 1,21–3,95). No quociente de inteligência total, o escore obtido foi de 84 no grupo exposto e 95 no grupo controle (p≤0,01). Quando ajustadas para outras variáveis potencialmente prejudiciais, a escolaridade materna elevada mostrou-se um fator atenuador do impacto da distância (OR 0,28; IC95% 0,11–0,72). A diferença encontrada entre os escores de quociente de inteligência verbal foi de 14 pontos (p<0,01); no quociente de inteligência de execução a diferença foi de 4 pontos (p=0,04).Conclusões: A distância entre a habitação e os sítios de reciclagem de resíduos pode reduzir habilidades cognitivas em escolares, mas esse efeito parece ser atenuado pela escolaridade materna. Essa associação reforça as preocupações sobre o impacto do manejo inadequado de resíduos urbanos, podendo vir a subsidiar a criação de políticas públicas que visem diminuir exposições ambientais potencialmente danosas.

Nineteen sites with 198 oriented-core samples have been collected from the Upper Permian-Lower Triassic volcanic rocks of Vien Nam Formation at Quynh Nhai locality, Son La Province, northwestern Vietnam. The characteristic remanent magnetization components carried by magnetite and hematite were successfully isolated from secondary components reveal a mean paleomagnetic direction Ds = 48.3°, Is = -10.0°, a95 = 8.0°, corresponding to a virtual geomagnetic pole located at l = 35.7°N, f = 217.4°E and a paleo-latitude of study area situated at 5.1°S during the Permian time. Compared with the Late Permian-Early Triassic pole of the South China Block (SCB), the data show that crustal elements of NW Vietnam have been close to, but not unequivocally a coherent part of the SCB, since the Late Permian. Development of the parallel NW-SE striking Song Ma and Song Chay orogenic belts did not involve the closure of wide (> 500 km) ocean basins.

Authors: B. Longpia C.
Published: May 2021

The PVL springs are used for both domestic and agricultural purposes. The seepage from the springs has resulted in producing a large expanse of wetlands and is therefore intensively use for dry season farming. The aim of this study was to determine the hydrogeological, hydrochemical characteristics, origin and their suitability for domestic and irrigation. The hydrogeology of the springs was determined by field mapping. The physico-chemical parameters were determined in the field and by laboratory methods. For the cation and anion analysis the ICP-MS and the wet methods were employed respectively. The stable isotope composition of oxygen (δ18O) and hydrogen (δ2H) were analyzed by Isotope Ratio Mass Spectrometer. The hydrochemical analysis revealed that the PVL springs waters are generally neutral with an average pH value of 7.3. The average TDS and EC values are 127.8mg/l and 246µs/cm respectively. These values fall within fresh water class. The average Mg2+,Ca2+, Na+ and K+ cation concentration values are 16.3mg/l, 15.8mg/l, 10.8mg/l and 5.58mg/l respectively. The average anions concentration of HCO3-, SO4 and Cl- are 140mg/l, 8.6mg/l and 3.4mg/l respectively. Piper trilinear diagram show that the spring waters is predominantly Mg-Ca-HCO3 water type with potable qualities based on WHO drinking water standards. The sodium Adsorption Ratio (SAR) and Sodium Soluble Percentage (SSP) values range between 0.44 to 0.84 and 26.4 to 54% respectively and falls within irrigation quality standards. Stable isotope compositions of δ18O and δ2H ranges from -3.60/00 to -4.90/00 and -200/00 to -280/00 respectively falls within the meteoric water composition. This is further affirmed by the δ2H versus δ18O plot on the correlation diagram with Standard Meteoric Water Line.

At this current digital era, business platforms have been drastically shifted toward online stores on internet. With the internet-based platform, customers can order goods easily using their smart phones and get delivery at their place without going to the shopping mall. However, the drawback of this business platform is that customers do not really know about the quality of the products they ordered. Therefore, such platform service often provides the review section to let previous customers leave a review about the received product. The reviews are a good source to analyze customer's satisfaction. Business owners can assess review trend as either positive or negative based on a feedback score that customers had given, but it takes too much time for human to analyze this data. In this research, we develop computational models using machine learning techniques to classify product reviews as positive or negative based on the sentiment analysis. In our experiments, we use the book review data from amazon.com to develop the models. For a machine learning based strategy, the data had been transformed with the bag of word technique before developing models using logistic regression, naïve bayes, support vector machine, and neural network algorithms. For a deep learning strategy, the word embedding is a technique that we used to transform data before applying the long short-term memory and gated recurrent unit techniques. On comparing performance of machine learning against deep learning models, we compare results from the two methods with both the preprocessed dataset and the non-preprocessed dataset. The result is that the bag of words with neural network outperforms other techniques on both non-preprocess and preprocess datasets.

Employees are the most valuable resources for any organization. The cost associated with professional training, the developed loyalty over the years and the sensitivity of some organizational positions, all make it very essential to identify who might leave the organization. Many reasons can lead to employee attrition. In this paper, several machine learning models are developed to automatically and accurately predict employee attrition. IBM attrition dataset is used in this work to train and evaluate machine learning models; namely Decision Tree, Random Forest Regressor, Logistic Regressor, Adaboost Model, and Gradient Boosting Classifier models. The ultimate goal is to accurately detect attrition to help any company to improve different retention strategies on crucial employees and boost those employee satisfactions.
An Incremental Learning Based Convolutional Neural Network Model for Large-Scale and Short-Term Traffic Flow
Authors:   School of Computer Science, Hangzhou Dianzi University, Hangzhou, China, Yu Feng , Fang Jinglong , Chen Bin , Shao Yanli
Published: May 2021

Traffic flow prediction is very important for smooth road conditions in cities and convenient travel for residents. With the explosive growth of traffic flow data size, traditional machine learning algorithms cannot fit large-scale training data effectively and the deep learning algorithms do not work well because of the huge training and update costs, and the prediction accuracy may need to be further improved when an emergency affecting traffic occurs. In this study, an incremental learning based convolutional neural network model, TF-net, is proposed to achieve the efficient and accurate prediction of large-scale and short-term traffic flow. The key idea is to introduce the uncertainty features into the model without increasing the training cost to improve the prediction accuracy. Meanwhile, based on the idea of combining incremental learning with active learning, a certain percentage of typical samples in historical traffic flow data are sampled to fine-tune the prediction model, so as to further improve the prediction accuracy for special situations and ensure the real-time requirement. The experimental results show that the proposed traffic flow prediction model has better performance than the existing methods.
Enhance System Utilization and Business Revenue with AI-based Queue Reservation System
Authors:   Department of Industrial Engineering, Faculty of Engineering, Kasetsart Univeristy, Thailand, Limlawan V. , Anussornnitisarn P.
Published: May 2021

Queue management is a crucial part of service industry. Business has to deal with the uncertainty of arrival customer and the trade-off between the costs of providing capacity and customer satisfaction. Matching service capacity with the arrival customer is difficult so the system utilization is low in the low periods and customers have to wait for a long time in the peak period. Due to long waiting, some customer abandons the queue before receiving service. Customer abandonment affects business revenue and the system utilization. To relieve the effect of the customer abandonment, this paper aims to propose Artificial Neural Network based waiting time predictor with queue reservation system. The proposed system increases the system utilization and increase customer satisfaction at the same time. Instead of abandonment, customers can reserve their place in queue if the waiting time is too long and they can do other activities while waiting. Moreover, the proposed system provides the accurate estimated waiting time to each customer instead of queue-length. The accurate waiting time enables arrival customers to better decide on the reservation options. 95% of our predicted waiting time is accurate within 5 minutes.

Authors: Jain Amrita , Asrani Sonia S.
Published: May 2021

Background: Iron deficiency is a common nutritional deficiency amongst women of childbearing age. Peri-partum iron deficiency anemia (IDA) is associated with significant maternal, fetal and infant morbidity. Ferric carboxymaltose (FCM) may be better tolerated than the conventional blood transfusions and oral iron supplements. The study was designed to assess the safety and efficacy of IDA correction with intravenous (I.V.) FCM in pregnant women with mild, moderate and severe anemia in their second and third trimesters and their post-partum period. Methods: Prospective observational study; Treatment effectiveness was assessed by repeat hemoglobin (Hb) measurements and patient report of well-being in the postpartum period. Safety was assessed by analysis of adverse drug reactions and fetal heart rate monitoring during the infusion.Results: Intravenous FCM infusion significantly increased Hb values above baseline levels in all women. Fetal heart rate monitoring did not indicate a drug related negative impact on the fetus. No serious adverse effects were found Conclusions: Our prospective data is consistent with existing observational reports of the safe and effective use of ferric carboxymaltose in the treatment of iron deficiency anemia in peri-partum period.

Background: Preterm birth is the leading cause of infant morbidity and mortality in the world. It affects not only the immediate neonatal period but also affects infancy, childhood and even adulthood. The aim of the study was to ascertain the causes and outcome of preterm labor and delivery and also the neonatal outcome.Methods: A hospital based cross-sectional study was conducted among patients who entered the third trimester of pregnancy and diagnosed as a case of threatened preterm labor or preterm labor from September 2017 to August 2019 in the department of obstetrics & gynaecology in collaboration with department of paediatrics, Regional institute of Medical Sciences, Imphal. Detailed clinical history and socio-demographic profile were recorded in pre-designed proforma. General physical examination and systemic examination and obstetrical examination was carried out for the participants.Results: Out of 918 preterm births 88.9% of neonates between the gestation period 28 weeks and <32 weeks were admitted to NICU. 48.8% of the neonates were having low birth weight. 23.8% of neonates required NICU admission and the most common neonatal complications were sepsis (5.2%), asphyxia (4%), jaundice (4%) and hyaline membrane disease (1.7%). Apgar score significantly improved as the period of gestation increased at 5 minute and 10 minutes (p=0.006 and p<0.001 respectively). The overall mortality among preterm births was 8.1% and only 3.7% neonatal deaths were seen in gestational age 34 weeks to <37 weeks, whereas 24.1% and 22.2% mortality were seen in 32 weeks to <34 weeks and 28 weeks to <32 weeks of gestation (p=<0.001).Conclusions: Preterm infants are at high risk for overall morbidity and mortality compared with term infants. Proper antenatal care, clinical suspicion, early detection and correction of risk factors, institutional delivery and good neonatal care facilities can improve the outcome of preterm labour.

Uterine sarcomas are rare soft tissue tumors which constitute 3% to 7% of overall uterine malignancies. Endometrial stromal sarcoma (ESS) is a rare type of uterine sarcoma arising from the mesodermal component of the body of the uterus. It constitutes around 0.2% of all the uterine tumors. It primarily occurs in perimenopausal women. One third of cases are seen in postmenopausal women. The presentation is not very different from an abnormal uterine bleeding, abdominal pain or a mass effect. Here we discuss an interesting case of 70 years female with a very common presentation of utero-vaginal prolapse but turned out to be a very rare postoperative diagnosis of uterine sarcoma.

One of the known complications after caesarean delivery is uterine caesarean scar defect or isthmocele. Isthmocele is usually asymptomatic or may cause gynecological problems, such as menometrorrhagia, infertility, chronic abdominal/pelvic pain. Isthmocele may cause obstetrical sequalae like preterm delivery, uterine rupture, caesarean scar pregnancy or abnormal placental implantation. In the present case report, asymptomatic patient underwent laparoscopic surgery for isthmocele repair after shared decision-making and medical treatment have been evaluated. We suggested that isthmoplasty should be offered to women with symptoms or if it is causing infertility.

Published: May 2021

Krukenberg tumor is a malignancy of ovary that metastasizes from a primary site. Krukenberg tumors are uncommon and account for less than 2% of all ovarian tumors. It is usually a bilateral involvement of ovaries from the metastatic deposit from adenocarcinoma of the stomach. Krukenberg tumors mostly occur after 40 years. Metastatic ovarian tumors in young age are very rare. Here, we reported a very rare case of bilateral Krukenberg tumors of the ovaries arising from a primary adenocarcinoma of the stomach in a 20 year old Indian female.

Background: Ovarian cancer is the second most common gynecologic malignancy. The aim of the study was to evaluate the tissue expression of HER-2/NEU and CA-125 in various epithelial ovarian carcinoma and assess the prognostic significance.Methods: A retrospective study was done in 76 cases of ovarian tumor. IHC was done in 16 cases of epithelial ovarian cancer with HER-2/NEU and CA-125.Results: Total number of cases were 76. Out of these 76 cases, 22 cases were malignant. 16 cases were malignant epithelial ovarian cancer. The highest incidence of malignant tumor was seen in the 41-50 years age group with 9 cases (11.84%). Out of 11 serous adenocarcinoma, 9 cases (81.8%) showed tissue expression of CA-125 and rest 2 cases (18.18%) did not show expression. All the 5 cases (100%) of mucinous adenocarcinoma did not show any tissue expression of CA-125. HER-2/NEU expression was positive in 7 out of 16 cases that is 43.75% and negative expression was seen in 9 out of 16 cases that is 56.25% of cases. Maximum HER-2/NEU positivity is seen among grade 3 tumors, that is (62.5%) (5 out of 8 cases).  Conclusions: The incidence of epithelial ovarian tumors are more common. The tissue expression of CA-125 on malignant epithelial ovarian tumors was studied, which showed positive expression in serous cystadenocarcinomas, but not in mucinous cystadenocarcinoma. HER-2/NEU expression was seen to be increasing with advanced grade of the tumors.

Background: The inspiratory parameters of pulmonary function test commonly used for various purposes in clinical practice including diagnosing airway obstruction. Expiratory portion of the flow volume loop of the pulmonary function test is studied in detail. The prediction equations for expiratory parameters are available for different population. However, the reference equation for inspiratory parameters is not available in Indian context. The current study derived the prediction equation for inspiratory parameters of pulmonary function test.Methods: The current study was carried out in school going 732 healthy girls and 1377 boys aged 6-15 years in India.  The children who meet the inclusion criteria were recruited in the study after detailed medical examination by registered medical practitioner. The lung function parameters were recorded by spirometry. The multivariate regression analysis was done to develop the prediction model.Results: The prediction equation for predicting inspiratory parameter were developed. This study revealed gender-wise and geographical variation in the inspiratory parameters. Hence this study recommends to derive gender wise prediction equations. The reference equations derived in this study can be used in population with similar background.Conclusions: Use of these equations for population having similar backgrounds will help for early and accurate diagnosis of the airway abnormalities in children. The inspiratory parameter assessment shall be included in the routine assessment of respiratory patient.
Correlation between serum ferritin level and severity of dengue fever in a tertiary care center: an observational study
Authors: Murmu Akash R. , R. Mubarak
Published: May 2021

Background: Serum ferritin is an acute phase protein and elevated levels of ferritin have been associated with the pathogenesis of many inflammatory infectious viral diseases. Dengue is a mosquito-borne tropical infection that caused by the dengue virus. TNFα and interleukin 1α, another proinflammatory cytokine, transcriptionally induce the H-chain of ferritin. Therefore, serum ferritin can be used as a prognostic marker for dengue severity.Methods: This is a case control study conducted between July 2017 to December 2018.Results: On the 3rd day of fever, the median values of serum ferritin in dengue, fever without warning signs, with warning signs, and severe dengue were 513.5 ng/ml, 1002 ng/ml and 2352.4 ng/ml respectively. On the 7th day of fever, the median values were 474 ng/ml, 900 ng/ml, and 2949 ng/ml respectively. Serum ferritin 1247 ng/ml on day 3 has a sensitivity of 96.4% and specificity of 91% for prediction of severity. Area under the curve for serum ferritin on day 3 was 0.963 (95% confidence limit: 0.934-0.991). Serum ferritin 1050 ng/ml on day 7 has a sensitivity of 98.2 % and specificity of 93% for prediction of severity. Area under the curve for serum ferritin on day 7 was 0.977 (95% confidence limit: 0.957-0.998).Conclusions: Elevation of serum ferritin was significantly seen in those with severe dengue. Serum ferritin can be used as a prognostic marker for dengue severity. Day 3 serum ferritin can be used as a prognostic marker for dengue severity.
