Essure no Brasil: desvendando sentidos e usos sociais de um dispositivo biomédico que prometia esterilizar mulheres
Authors: Brandão Elaine Reis , Pimentel Ana Cristina de Lima
Published: April 2020

Resumo Denúncias graves de efeitos colaterais sofridos por mulheres em vários países (Estados Unidos, nações da Europa e Brasil) desvelaram controvérsias na difusão de um dispositivo permanente para controle reprodutivo, designado Essure, pelo laboratório farmacêutico Bayer. Este trabalho busca compreender a circulação internacional e a introdução desse artefato biomédico no Brasil, a partir de pesquisa documental em sites de agências regulatórias, do laboratório farmacêutico e da divulgação pública feita por hospitais no país, associados ao Sistema Único de Saúde, para convocarem mulheres para o procedimento. Trata-se de primeira aproximação ao tema para se inquirir sobre as condições sociais da implantação do dispositivo em usuárias desses serviços de saúde no período em que ele esteve disponível no país, de 2009 a 2017. Apresentado como um dispositivo seguro, inócuo e de fácil manejo clínico, a promessa de um objeto permanente que impediria a gravidez sem necessidade de recorrer ao método cirúrgico foi vendida pela Bayer ao staff médico como solução simples, prática e moderna de controle reprodutivo. O percurso do dispositivo no Brasil evidencia certo entusiasmo médico com a nova técnica, não acompanhado de monitoramento clínico de longo prazo, principalmente quando as mulheres passaram a demandar a sua retirada em razão de muitas sequelas e efeitos colaterais dele decorrentes.
A study on three different hydropower operation rules by monthly and daily time steps
Authors: Haktanir Tefaruk , Aydemir Alper , Acanal Nese
Published: April 2020

Operation simulation models are developed for monthly and daily time steps for computing the hydroelectric energy and its financial benefits in an economic life by three different operation policies: steady-rate, three-shift and pumped-storage rules. The pump is operated during the night and consumes low-cost energy. The resulting computer programs, three on monthly and three on daily steps, are applied to the Yamula dam – which is a fairly large dam generating energy, located in the Inland Anatolia region of Turkey – over a period of 35 years using the gauged daily stream flows and daily pan evaporations. The results indicate that the pumped storage is more profitable than the other two rules aside from the intangible benefits of regulating the within-day fluctuations of demand for electrical energy. Another result is that both the average annual energy and the financial benefits given by the three rules computed by the monthly time steps are about 1−2% greater than those given by the daily time steps. This study is the first one comparing all these three operation schemes quantitatively in a realistic way both in monthly and daily time steps.

Published: April 2020

Okuma günlük hayatta sıkça kullanılan ve bireyin öğrenim hayatına yön vermesi açısından önemli olan bir beceri alanıdır. Okuma becerisinin geliştirilmesi, zayıf okuyucuların daha iyi okuyucular hâline gelmesinin sağlanması ve bireylerin okuma alışkanlığını kazanmaları Türkçe dersinin hedeflerinden biridir. Okuma becerisi sadece Türkçe dersi ile ilgili gibi görünse de öğrencinin diğer alanlardaki başarısı ve öğrenme düzeyi okuduğunu anlama becerisinden geçmektedir. Bu nedenle okuma becerisini geliştirmeye ve okuduğunu anlama düzeyini arttırmaya yönelik farklı çalışmalar yapılmaktadır. Okuma becerisi karmaşık bir bütünden oluştuğundan okumanın geliştirilmesinin pek çok farklı yolu bulunmaktadır. Bu yollardan biri bireylerin okuma stratejilerini etkili kullanmalarından geçmektedir. Bu araştırmada üniversite öğrencilerinin okuma stratejileri üstbilişsel farkındalıklarının etkilendiği değişkenleri belirlemek amaçlandığından araştırma problemi "Üniversite öğrencilerinin cinsiyet, yaş ve günlük ritim özellikleri okuma stratejileri üstbilişsel farkındalıklarını anlamlı düzeyde yordamakta mıdır?" olarak belirlenmiştir. Araştırma korelasyonel bir araştırmadır ve araştırmaya Sakarya Üniversitesi Eğitim Fakültesi’nde formasyon eğitimi alan 818 öğrenci katılmıştır. Araştırmada bağımlı değişken katılımcıların okuma stratejileri üstbilişsel farkındalıkları, bağımsız değişkenler bağımlı değişken üzerinde etkileri incelenen cinsiyet, yaş ve günlük ritim özellikleridir. Araştırmada okuma stratejileri üstbilişsel farkındalık ölçeği, günlük ritim ölçeği, kişisel bilgi formu kullanılarak veriler toplanmış ve verilerin analizinde SPSS 20 programı kullanılmıştır. Araştırma bulgularına göre öğrencilerin okuma stratejileri üstbilişsel farkındalıkları yaş, cinsiyet ve günlük ritim özelliklerinden etkilenmektedir. Araştırma sonuçlarına göre öğrencilerin yaşı arttıkça okuma stratejileri üstbilişsel farkındalıkları artmaktadır. Ayrıca kadınların okuma stratejileri üstbilişsel farkındalıkları daha fazladır. Günlük ritim tercihleri açısından okuma stratejileri üstbilişsel farkındalıklar incelendiğinde gündüzcü ritim tercihi olan öğrencilerin okuma stratejileri üstbilişsel farkındalığının daha yüksek olduğu tespit edilmiştir.

Sosiale weerbaarheid, strukturele kwesbaarheid en instaatstellende geleenthede in Genadendal, Suid-Afrika
Authors: Conradie I , Hüman-Hendricks A , Roman N
Published: April 2020

Die dorpie Genadendal in die Wes-Kaap is in 1837 deur die Morawiese Kerk gestig. Ons het 'n reeks in-diepte kwalitatiewe onderhoude met twaalf afgetrede inwoners van die dorp gevoer en hulle belewenisse en herinneringe geanaliseer om hulle geleenthede, sosiale weerbaarheid en strukturele kwesbaarheid te evalueer. Ons gebruik Amartya Sen se benadering van Instaatstellende Geleenthede ("capability approach"), sowel as Weerbaarheidsteorie (kyk voetnoot 2) as teoretiese raamwerke. Ons het gevind dat daar 'n baie sterk sosiale verbondenheid bestaan het terwyl die deelnemers grootgeword het, wat hulle meer weerbaarheid gegee het gedurende die apartheidsperiode. Na die oorgang na demokrasie het hulle werksgeleenthede en geleenthede vir beter integrasie in die breë samelewing uitgebrei, maar as gevolg van die feit dat Kaapse bendefamilies in Genadendal ingetrek het, het hulle op nuwe maniere struktureel kwesbaar geword. Die analise van geleenthede, sosiale weerbaarheid en strukturele kwes-baarheid in Genadendal tydens en na apartheid illustreer die belewenisse van 'n atipiese, afgesonderde landelike gemeenskap in die Wes-Kaap tydens hierdie twee historiese periodes.
'n Kritiek op normatiewe konstruksies van ouderdom in vier intertekstueel verbinde tekste: Alba Bouwer se Stories van Rivierplaas, Reza de Wet se Diepe Grond en African Gothic, en Etienne Kallos se Eersgeborene
Authors: Stander D
Published: April 2020

Hierdie artikel ondersoek die intertekstuele verhouding tussen 'n groepering tekste deur drie Suid-Afrikaanse skrywers uit drie generasies: Stories van Rivierplaas (1955-6) deur Alba Bouwer; Diepe Grond (1985), 'n drama deur Reza de Wet asook De Wet se eie Engelse vertaling en verwerking van Diepe Grond as African Gothic (2003) en Eersgeborene (2009), 'n kortfilm deur Etienne Kallos. Onder die drie skrywers kan slegs Bouwer se werk geklassifiseer word as kinderfiksie. Tog is De Wet en Kallos se tekste nie alleenlik verwerkings en toeëienings van Stories van Rivierplaas nie, maar hulle tematiseer ook kindskap en kinderjare. Ten einde Bouwer, De Wet en Kallos se kritiek op normatiewe konstruksies van ouderdom te bespreek, gebruik ek Maria Nikolajeva se konsep van "aetonormatiwiteit", 'n ouderdomsgebaseerde norm en die spesifieke aanname dat volwassenes en volwasse ervarings normatief is, terwyl die belewenisse van 'n kind daarenteen geklassifiseer moet word as afwykend (2010:8). Aetonormatiwiteit kan dus beskryf word as 'n soort performatiwiteit ("performativity") soos Judith Butler dit omskryf, dit wil sê 'n subjekposisie wat deur middel van sosiale meganismes voorgestel word as 'n ontologiese essensie, terwyl daar geen universele konsensus of bewys van die natuurlikheid daarvan bestaan nie (Butler 1999:viii). In lyn met die geanaliseerde tekste se tematiese gemoeidheid met kinderjare en ouerskap, gebruik ek die metafoor van moederskap om die konstruksie van 'n genetiese lens aan te wend en ek beskryf die tekste se verhouding tot mekaar as kompleks, in teenstelling met eenvoudig vyandig of korrektief.
"Egtheid" in beeide: Die verwerking van verbatim tekste na verhoogbeelde met spesifieke verwysing na tot stof \ tot stilte - 'n paniekreaksie (2018)
Authors: Gerber A
Published: April 2020

Hierdie artikel ondersoek die verwerking van verbatim teks na verhoogbeelde deur 'n ontleding van die jeugteaterproduksie getiteld tot stof | tot stilte - 'n paniekreaksie wat deur die Hoër Meisieskool Bloemhof in 2018 opgevoer is. 'n Ondersoek word gedoen na die konvensionele skeppingsmetodologie van verbatim teater. Daar word krities gekyk na die data-insamelings-, seleksie- en redigeringsproses van die gesproke teks. Daar word tot die gevolgtrekking gekom dat die seleksie- en redigeringsproses van die gesproke data-verwerkings van verbatim teks nie noodwendig die volledige omvang van die rou data vasvang nie. Dit is veral die geval wanneer die rou data nie noodwendig toneelmatige trefkrag het wanneer dit byvoorbeeld as teaterdialoog beskou word nie. Deur gebruik te maak van Lehmann (2016) se teorieë van postdramatiese estetika argumenteer ek in hierdie artikel dat 'n verwerker die rou gesproke data na beelde kan omskep om die kontekste, inhoud en prosesse van die data-insamelingsproses vas te vang. Hierdie verwerking kan as potensieel meer "eg" beskou word omdat daar moontlik 'n breër omvang van die rou data uitgebeeld kan word, veral gegewe sekere kontekstuele beperkings (die teatermatige ervaring van die spelers, of die lengte van die toneelstuk in verhouding tot die rou data). Deur die klem van die produksie op die verhoogbeelde te plaas, word die implisiete kunsmatigheid van verbatim teater belig. Daardeur word die problematiek van lewensgetrouheid, "egtheid" en die "samestelling van egtheid" in beide die verbatim vorm en verwerkingspraktyk op 'n nuwe manier ondersoek.
Oskar en die Pienk Tannie: Die reis van 'n onwaar-skynlike tweemanskap van 'n Franse na 'n Afrikaanse verhoog
Authors: Morgan N
Published: April 2020

Eric-Emmanuel Schmitt, die skrywer van die novelle en eponieme drama Oskar en die pienk tannie, is een van Frankryk se mees gewilde en bekroonde outeurs. Hy word beskou as 'n dramaturg vir akteurs eerder as regisseurs: sy intriges is maklik om te volg en sy natuurlike dialoog is 'n groot aantrekkingskrag vir bekende teater- en filmakteurs. Gegewe sy onbekendheid in Suid-Afrika was dit egter 'n groot uitdaging om belangstelling vir die novelle en dramaverwerking deur Schmitt self by Afrikaanse uitgewers, regisseurs en produsente te wek. Die gedomestikeerde Afrikaanse dramavertaling is uiteindelik deur Sandra Prinsloo-produksies opgevoer met die aktrise self as Oskar èn die pienk tannie en Lara Bye as regisseuse. Danksy die sukses van die produksie is die novelle-vertaling die daaropvolgende jaar gepubliseer. Die dramaproduksie het uiteindelik toekennings vir beste aktrise, regisseuse en produksie op verskillende Afrikaanse kunstefeeste gewen. Oskar en die pienk tannie kan beskou word as een van die mees suksesvolle vertaalde dramas wat die afgelope paar jaar in Afrikaans op Suid-Afrikaanse verhoë opgevoer is. As speelteks is die Afrikaanse dramavertaling verder aangepas deur Sandra Prinsloo en Lara Bye; die outeurskap van die speelteks van die Bye-produksie word bespreek na aanleiding van Sirkku Aaltonen se Time-sharing on stage (2000). Die oorspronklike Franse en Afrikaanse produksies word vergelyk as bydrae tot die enscenerings-argief van Afrikaanse teaterproduksies. Daar word ook kortliks na die terapeutiese waarde van hierdie besondere dramateks verwys.
Die triomf van die silwerdoek: Christiaan Olwagen se filmverwerking van Die seemeeu
Authors: van Niekerk J , van der Merwe M
Published: April 2020

Hierdie artikel ontleed enkele aspekte van Christiaan Olwagen se 2018-filmverwerking van Anton Tsjekow se drama Die seemeeu. In hierdie verwerking is die gegewe van die oorspronklike dramateks verplaas na die vroeë negentigerjare van die twintigste eeu in Suid-Afrika, 'n tydperk van ommekeer vir die Afrikaanse teaterbedryf. Olwagen se verwerking beeld die noodsaak vir hierdie verandering uit, maar lewer ook kommentaar op die kuns van verwerking ("adaptation") en die huidige stand van die Afrikaanse drama- en filmwereld. Dit span doelbewus simboliek en stereotipes in wat deur sommige Tsjekow-kenners verwerp sou word met die doel om aan die vereistes van die gehoor, spesifiek die filmkyker, te voldoen. Daar word aangetoon dat ofskoon Die seemeeu 'n verwerking is, dit vormlik en tematies aansluit by die ander films in Olwagen ('n moontlike auteur-regisseur-in-wording) se oeuvre.
INVITED ARTICLE: Building Journal Impact Factor Quartile into the Assessment of Academic Performance: A Case Study
Authors: ORBAY Keziban , MİRANDA Ruben , ORBAY Metin
Published: April 2020

This study aims to provide information about the Q Concept defined as the division of journal impact factors into quartiles based on given field categories so that the disadvantages resulting from the direct use of journal impact factors can be eliminated. While the number of "Original articles published in the Web of Science (WoS) database-indexed journals like SCI, SSCI and A&HCI" is an important indicator for research assessment in Turkey, neither the journal impact factors nor the Q Concept of these papers have been taken into account. Present study analyzes the scientific production of the Amasya University researchers in journals indexed in WoS database in the period 2014-2018 using the Q concept. The share of publications by Q category journals as well as the average citations received by the works from Amasya University were compared to the average situation in Turkey and other different countries in the world. Results indicate that the articles published by Amasya University researchers were mostly published in low impact factor journals (Q4 journals) (36.49%), in fact, only a small share of papers were published in high impact journals (14.32% in Q1 journals). The share of papers published in low impact journals by researchers from Amasya University is higher than the Turkish average and much higher than the scientific leading countries. The average citations received by papers published in Q1 journals was around six times higher than papers published in Q4 journals (8.92 vs. 1.56), thus papers published in Q1 journals received 30.02% citations despite only 14.32% of the papers was published in these journals. The share of papers published which were never cited in WoS was 27.48%, increasing from 9.68% in Q1 to almost half (48.10%) in Q4. The study concludes with some suggestions on how and where the Q Concept can be used.

Published: April 2020

Obstructive sleep apnea hypopnea syndrome (OSAHS) is a common condition; when conservative approaches are not effective, surgical techniques aimed at reducing the airway obstruction effect are used. This retrospective study aimed at comparing the functional outcomes in patients with OSAHS undergoing uvulopalatopharyngoplasty (UPPP) according to Fairbanks and barbed reposition pharyngoplasty (BRP) according to Mantovani, with or without hyoid suspension (HS). One-hundred twenty-two consecutive OSAHS patients who underwent surgical treatment were included in the study. Patients were divided into 4 groups; all patients underwent preoperative and postoperative polysomnography (PSG) with apnea/hypopnea index (AHI) and oxygen desaturation index (ODI) evaluation, and Epworth Sleepiness Scale (ESS) evaluation. The results were analyzed according to the different surgical procedures, in relation to the preoperative PSG and anthropometric data. A significant reduction was observed at 18-month follow-up for patients in BRP group for BMI (p = 0.004), ESS (p < 0.0001), ODI (p < 0.0001), and AHI (p < 0.0001). Risk factors for poor postoperative AHI reduction were evaluated; preoperative AHI was the strongest independent protective factor, while preoperative ODI was the strongest risk factor. The association of HS with UPPP or BRP showed significant results in terms of higher postoperative AHI reduction only when associated to UPPP (p < 0.0001). This study showed that the BRP technique was more effective compared to UPPP for patients with OSAHS. The association of HS showed greater benefits in UPPP compared to BRP.  Randomized prospective trials with longer follow-up are necessary to confirm our results and formulate a more accurate indication of the optimal therapeutic strategy.

Published: April 2020

We report a urea-amino sugar clearing reagent for the murine liver that rapidly renders the tissue clear with preservation of native architecture, fluorescent proteins and lipophilic dyes. Optical clearing protocols for three-dimensional (3D) imaging, such as confocal or light sheet microscopy, can consist of several steps and solutions, complex apparatuses, or days to weeks for whole-organ clearing. Established protocols that demonstrate efficient clearing can unfortunately quench endogenous proteins, whereas some methods formulated to preserve protein fluorophores can be underwhelming in clearing capability. Many clearing methods have been optimized for neural tissue, with little described for the liver. Our method, a single step modified protocol of the UbasM protocol created by Chen et al., uses Ub-1 to clear the murine liver with only 24 hours incubation and one simple solution. We additionally describe a technique for labeling the murine intrahepatic biliary tree and vasculature. Our methods can benefit investigations of tissue composition and structural relationships in 3D.

Social Media as a Disguise and an Aid: Disabled Women in the Cyber Workforce in China
Authors: Zheng Jing , Pei Yuxin , Gao Ya
Published: April 2020

Existing literature shows that people living with physical impairment are systematically disadvantaged in the workforce and their voices are often silenced. With a perspective of intersectionality, this article looks into how disabled women suffer from multiple forms of discrimination and how social media may emerge as a tool of empowerment for them in both the workforce and their everyday lives. Drawing on five cases of Chinese disabled women in the cyber workforce, the study finds that the booming Internet economy enables more disabled women to financially support themselves. Social media appears as a cover for these women to disguise their disability identity and get more job opportunities. It serves as an aid in many cases to allow these women to increase social participation, to project their voice, and to form alliances. The risks and challenges that disabled women often encounter in the cyber workforce are also discussed.

Published: April 2020

The essence of labor potential of Kyiv region and its taxonomic levels is revealed. There are 4 thematic blocks of development of labor potential: environmental, demographic, economic and cultural blocks. 13 indicators of formation and use of labor potential in the district dimension were calculated. The integral rank of development of labor potential for each district is calculated. The ranking of the districts of the Kiev region by the values ​​of block indexes. The spatiotemporal framework of the development of labor potential is substantiated. Cluster analysis was performed using the Vard and K-means methods. The existence of hierarchical clustering of districts in the selected three clusters by the level of development of labor potential is established. Clusters are identified: outsider areas and buffer areas. The existence of the core of the development of labor potential of Kyiv region is substantiated. The presence of a fixed space-time frame of labor potential is established. Three types (groups) of districts were identified according to the studied indicator. The field of differentiation of districts of Kyiv region by the magnitude of the basic increase of the integral rank of development of labor potential is revealed. The level of polarization of labor potential development or the gap between the maximum and minimum value of the integral rank of labor potential development is established. A centre-peripheral model of labor potential development has been constructed. The dynamics of the integral rank of development of labor potential in the section of districts is analyzed. Four are identified:1) central or core / central areas; 2) districts of semi-peripheral type or semi-peripheral areas; 3) peripheral or peripheral areas; 4) lacunar type areas or lacunar areas (areas that are exceptions to the rules of center-peripheral spatial distribution). The specifics of formation, functioning of districts are revealed and the main problems and perspective directions of their development are highlighted.
A difusão do agronegócio nos cerrados do centro norte brasileiro e nas áreas irrigadas da caatinga nordestina
Authors: Oliveira Thiago José Arruda de , Rodrigues Waldecy
Published: April 2020

O estudo compara duas áreas que se inseriram no contexto econômico via difusão do agronegócio: os Cerrados do Centro Norte brasileiro, especializados na produção de grãos, e as áreas irrigadas da Caatinga nordestina, com predominância no plantio de frutas. Em comum, são consideradas Regiões Produtivas do Agronegócio (RPA), dado que possuem polos regionais onde localizam-se as empresas e holdings que são responsáveis pela consolidação dessas cadeias agrícolas em suas zonas de influência, delimitadas através do conceito de Região Geográfica Imediata, elaborado pelo Instituto Brasileiro de Geografia e Estatística (IBGE). Para tanto, utilizou-se da análise de agrupamentos com o propósito de identificar a intensidade das suas semelhanças e diferenças. Os resultados apontaram que a região de Barreiras(BA) auferiu um patamar superior ao abrigar grandes quantidades de empresas que apoiam o plantio intensivo de grãos. Sobre as demais, restrições de ordem física, climática e de infraestrutura impedem a atração de novos agentes do agronegócio. Diante disso, concluiu-se que a tecnologia é um fator dominante, uma vez que as inovações influenciam na produtividade, diversificação, tempo de colheita e na logística, e as empresas se inserem nesse contexto ao disponibilizar tais serviços. A junção desses elementos é a que torna as RPAs diferentes umas das outras.

Published: April 2020

As organizações vêm sendo cada vez mais pressionadas a mudarem as formas de produzirem e de extraírem matéria-prima da natureza. Estas mudanças, muitas vezes, têm ocorrido por meio de inovações que trazem benefícios ao meio ambiente, sejam elas em processos, produtos, tecnologias ou mercados. Neste contexto se encontram os laticínios, que fazem parte da importante atividade econômica do complexo agroindustrial do leite. Estes também têm sido levados a atuarem de modo ambientalmente favorável, por pressão do mercado e por exigências da legislação. Este estudo avaliou as racionalidades presentes nos discursos dos gestores de laticínios quanto à inovação ambiental. Estes laticínios operam na região do Alto Paranaíba, Estado de Minas Gerais. Trata-se de um estudo qualitativo e, como método, recorreu-se ao estudo de casos múltiplos. Os dados foram coletados por meio de entrevistas semiestruturadas e analisados sob a técnica da análise de conteúdo de Bardin. Identificou-se o predomínio da racionalidade instrumental nos argumentos, pois a maioria deles se referia às mudanças nos processos empresariais motivadas, principalmente, por fiscalização, ou seja, como uma forma de se adequarem à legislação vigente e, assim, evitarem multas e outras penalidades.
District-level analysis of climate vulnerability and household nutrition status among rural communities in Odisha, India
Authors: Acharya Arabinda , Das Anup Kumar
Published: April 2020

Good nutrition is the foundation of human well-being that leads to better health, effective engagement of the workforce, and productive lifestyle, resulting in higher income and an integrated development trajectory. This paper attempts to comprehend the impact of climate vulnerability on household nutrition status through agriculture production systems in Odisha, India. This study using secondary data estimates a composite index of climate vulnerability on the agriculture ecosystem in Odisha at the district scale. Results suggest that among all the districts in Odisha, Bhadrak (0.193) is the most vulnerable district followed by Sonepur (0.191) and Baudh (0.190). On the other hand, Mayurbhanj (0.099) is the least vulnerable district followed by Ganjam (0.103) and Sundargarh (0.105). The fi ndings also suggest that there is a wide variation in vulnerability indicators among the districts in Odisha (0.099 – the lowest district value vs. 0.193 – the highest). The results of multivariate analysis evince that in households (both women and children) nutritional status, the composite value of “climate vulnerability” has a greater role in predicting the predictors in Odisha through the agriculture production system. The climate vulnerability has a positive and signifi cant relationship with forest area (r=0.403*), gross cropped area (r=0.489**), percent of scheduled caste population (r=0.510**), percent of urban area (r=0.427*), and per-capita income (r=0.712**). The fi ndings also signify that district-wise gross cropped area (t=3.01), average annual rainfall (t=4.05), area under irrigation (t=3.36), cropping intensity (t=3.60), and forest areas (t=1.81) play a more predictive role to determine the household nutritional status along with socioeconomic and health factors such as per-capita income (t=1.8), urbanization (t=1.91), and women’s anemic status (t=2.74). Drawing inferences from the empirical evidence, the study suggests that climate vulnerability has a much greater role in influencing household nutrition status, particularly with women and child nutrition through the agriculture production system. Appropriate policy level measures for climate-sensitive and adaptive action are the need of the hour to make agriculture production ecosystem contributes positively to nutrition status.
The sunshine vitamin D: ubiquitous source, still so deficient in mother and baby duo
Authors: K. Shilpa S. , Fatima Naima
Published: April 2020

Background: Vitamin D is a fat-soluble vitamin, a sunshine vitamin. Vitamin D deficiency is now recognized as a pandemic. Fetus depends on mother for its need of vitamin D, thus there is growing concern for its impact on neonates. This study was designed to determine the correlation between 25-hydroxyvitamin D (vitamin D3) levels in maternal blood and in cord blood.Methods: A total 50 term pregnant women attending antenatal clinic at SVS medical college, Telangana and their neonates were included in the study. At term after taking written consent, maternal and cord blood vitamin D3 were measured, and values were correlated. Antenatal and neonatal complications were noted, and correlated with vitamin D3 levels.Results: In this study 80% of pregnant women and 88% of neonates were vitamin D3 deficient. Mean maternal blood vitamin D3 was 17.62±10.01 and cord blood vitamin D3 was 12.84±7.68. Maternal blood vitamin D3 correlated positively with cord blood vitamin D3 (r=0.951, p<0.001). Antenatal and neonatal complications were observed, but statistically significant association with vitamin D3 deficiency could not be established.Conclusions: This study has demonstrated a very high prevalence of vitamin D deficiency in apparently healthy, young, pregnant women despite abundant sunlight leading to deficiency in their neonates. To establish strong association between vitamin D3 deficiency and various antenatal and neonatal complications further studies with large subject groups are required.
Distracted multinomial model for corona screening at entry ports
Authors: Shanmugam Ramalingam
Published: April 2020

Background: On 24 January 2020, 1287 corona cases were noticed in Wuhan, China, causing 41 deaths. Its incubation period is at least 14 days. Now, this deadly virus has spread to other foreign countries. The prevalence of corona cases is changing daily. See www.who.org for daily reports. The corona cases are mystic and nightmare to the public, health professionals, and governing agencies globally.Methods: The Center for Disease Control (CDC) compiled in their webpage (www.cdc.org) the number of confirmed, number of healthy, and the number of pending cases at the port of entries in United States of America (USA). These numbers are perhaps under-estimates because of inappropriate diagnostics and imprecise incubation period. To resolve the under estimating, this article, introduces a distracted multinomial model to refine the imprecise corona screening process and interpret the probability of detecting a corona case in US entry gates.Results: An alternate expression (2) for the correlation between the corona ill and corona free cases at the USA ports of entry reveals that it was rising since 31st January 2020, reached its maximum on 5th February 2020, then declined to hit a bottom on 7th February 2020 only to rise again.Conclusions: Most desirable is an accurate predictability of a traveller with the corona virus at the portal entry to minimize its spread. To make such prediction, a regression is necessary with involvement of covariates like age, body’s immunity level, comorbidity, and precise understanding of its incubation period. The model in this article is the starting point for further future research work.

Background: Dopamine is an important component in the pathophysiology of ADHD. Dopamine synthesis is regulated by the enzyme tyrosine hydroxylase and influenced by iron deposits in the brain. Several studies have shown that low ferritin levels in children with ADHD and iron supplementation are said to show good clinical outcomes, but this study has never been conducted at Sanglah General Hospital.Methods: This study used an observational analytic study design with unpaired case control design. Research held in Policlinic RSUP Sanglah from July 2018 to April 2019.Results: In a total of 25 children with ADHD and 25 children without ADHD, median ferritin level was 43.7(7.9-77.0) in the case group and 68.2(33.1-319.0) in control group. Bivariate analysis of ferritin level categories using the chi-square test showed significantly different results. Low ferritin levels (<45 ng/mL) was obtained in 56% of the case group and 16% in the control group. Odd ratios determine the relationship between ferritin and the incidence of ADHD at 6.7 (95% KI 1.8-25.2). The results of multivariate analysis showed that adjusted OR was 6.5(95% KI 1.2-34.6) and was statistically significant with p value 0.027.Conclusions: There was correlation between ferritin levels and ADHD in children.

Background: To compare bone mineral densities via dual energy X-ray absorptiometry method (DXA) between various hyperparathyroidism (HPT) types such as primary, vitamin D induced secondary, and both conditions.Methods: Participants who were aged between 18-45 years and had elevated parathyroid hormone levels were included. After initial evaluations, patients were divided into 3 groups according to diagnoses: primary HPT (pHPT), vitamin D induced secondary HPT (sHPT), and combined (primary+secondary) one. In addition to the bone mineral density (BMD), demographic and laboratory datas were recorded.Results: Of 166 patients, 147 of the patients were female, 19 were male, and average age was 38.10±7.24 years. Significant difference was found in terms of age (p=0.03) between pHPT and sHPT. Blood calcium, PTH, 25-OH vitamin D, and daily urine calcium excretion levels were significantly higher and phosphorus levels were lower in the pHPT group compared to the sHPT and combined disease group. Both T and Z scores of the pHPT group were significantly lower than the sHPT group especially in the lumbar region. However, no significant difference was noted between pHPT and combined disease group with respect to T and Z scores in all regions.Conclusions: The results of this study indicate that pHPT has a significantly worse impact on skeletal mineral density particularly in the lumbar region than sHPT. The addition of vitamin D deficiency to the clinical picture seems to have no significant influence on BMD in pHPT. To confirm and clarify these findings, prospective studies with larger number of participants are needed.

Published: April 2020

Background: Non-alcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease in the United States and other industrialized countries, many study has identified NAFLD as a risk factor not only for premature coronary artery disease and cardiovascular events, but also for early subclinical abnormalities in myocardial structure and function. Aim of this study was to the presence of NAFLD in patients with Ischemic Heart Disease (IHD) and Relation of NAFLD with other risk factors of IHD.Methods: The study group consisted of 150 patients that comply with inclusion criteria and selected of 100 consecutive patients who underwent coronary angiographies. Coronary artery disease was defined as a stenosis at least 50% in at least one major coronary artery. Fatty liver was diagnosed by abdominal ultrasonography (4 stages: Grades 0, 1, 2 and 3). Statistical evaluations were performed using T test, Chi- square test.Results: The present study was done in 100 patients of coronary artery disease divided into two groups i.e. Non NAFLD group n= 62 (62%) and NAFLD group n= 38 (38%). The present study shows that the prevalence of NAFLD was highest (86.8%) in more than 40 years of age group. The present study shows that the prevalence of NAFLD was more in males (84.2%) as compare to females (15.8%). The present study also shows significantly high incidence of metabolic syndrome in patients with NAFLD (23.7%) as compared to Non-NAFLD (3.2%) patients with Coronary Artery (CAD).Conclusions: The presence of fatty liver and its severity should be carefully considered as independent risk factors for IHD. The study results suggest the synergistic effect in between fatty liver and deranged lipid profile for developing IHD. Abdominal ultrasonography may provide valuable information about IHD risk assessment.

Published: April 2020

Background: Recent studies suggest that the incidence and severity of tuberculosis is associated with low levels of Vitamin D, this is especially important in developing countries like India which carries a major portion of global Tuberculosis burden. Therefore, this study aimed to determine the prevalence of Vitamin D deficiency in newly diagnosed tuberculosis patients in our institute. Aims and objective is to study the deficiency of Vitamin D In newly diagnosed sputum positive pulmonary TB and to compare the level of Vitamin d with that of age matched healthy control population.Methods: This was a descriptive cross-sectional case control study to asses Vitamin D deficiency among 140 cases which included 2 categories of patients (a) Group 1: 70 sputum AFB positive newly diagnosed pulmonary TB patients, (b) Group 2: 70 apparently healthy people who came to the hospital with regular checkup.Results: Mean age of study groups and control in years were, Control: 40.3857±10.231, Cases: 36.885±11.076. Mean BMI was significantly higher in controls when compared with new TB cases (19.27±2.455 vs 15.215±1.774) kg/m2 p <0.05).There was significant decrease in mean Vitamin D3 value when new cases TB patients were compared with controls (18.212±9.3027 vs 36.1267±8.410 p <0.05).Conclusions: Patients with tuberculosis are significantly Vitamin D deficient as compared to normal people. This deficiency is more marked in females and those with low BMI. The present finding favours the role of Vitamin D in the prevention and treatment of tuberculosis in developing countries like India.

Background: Stroke is one of the leading causes of mortality and morbidity worldwide. In this study, authors worked on clinical presentation and types of stroke. The two main types of strokes are ischemic and haemorrhagic. Brain infarction is caused by decrease blood flow due to either narrowing of artery or complete obstruction to blood flow owing to embolism. While haemorrhage is caused by rupture of artery or aneurysms leading to accumulation of blood in the brain parenchyma.Methods: Cross sectional study of group of patients in Nishtar hospital Multan, Pakistan who presented with variety of neurological symptoms who were subsequently diagnosed as non-traumatic stroke. All patients were subjected to a detailed history and thorough clinical examination and investigations after obtaining informed consent.Results: Of 122 patient, 66 patients were male and 56 were female. Ischemic stroke was more common: present in 76 patients as compared to 46 patients with hemorrhagic stroke. Hypertension was present in 40.9% of ischemic stroke and 27.8% of hemorrhagic strokes. Most of the patients (67.2%) had altered sensorium at presentation followed by hemiplegia in 39.3 % of patients.Conclusions: Prevalence of ischemic strokes is higher than that of haemorrhagic stroke. Hypertension is associated with both types of these strokes. Moreover, hyperglycaemia and high blood pressure are common in early phase of stroke. Vomiting in stroke favors haemorrhagic stroke.

Background: Maternal mortality is a vital index of the effectiveness of obstetric services prevailing in a country. The key to progress of a country lies in reducing its maternal morbidity and mortality, hence to give a better assessment of the problem a retrospective study on maternal mortality was carried out. An objective of the study was to find the cause and epidemiological factors for maternal mortality in a tertiary care hospital in western Maharashtra from January 2018 to August 2019.Methods: A retrospective, descriptive study done at tertiary care hospital in western Maharashtra from January 2018 to august 2019. Data was collected from medical records department and the study was conducted by reviewing the records of maternal death and scrutinizing for various aspects likely to be related to maternal death such as age, locality of residence, antenatal care, admission death time interval and cause of death.Results: during the study period 63 maternal deaths occurred and 75302 live births, Maternal Mortality Ratio were 83.66 per 1 lakh live birth. 46% of maternal deaths were in age group of 21-25 years, 87% of patients belonged to rural area, 74% belonged to lower socioeconomic status. 43%  were unregistered patients, 43% had vaginal delivery, 73% had no free transportation, 68% were referred patients, 60% were referred from private hospitals, 48% of maternal death occurred <24 hours, 73% of maternal death were due to direct cause, 28% of maternal deaths were due to pre-eclampsia and its complications, 15.8% due to sepsis and 12.6% due to Postpartum hemorrhage.Conclusions: Being a tertiary care hospital, where patients are referred from periphery maternal mortality was found to be on higher side. Proper implementation of government policies with community participation along with strengthening of First Referral Unit (FRU) and Primary Health Centres can help to reduce maternal mortality.

Authors: Singh Amrendra K. , Raghuvanshi Gyanendra
Published: April 2020

Background: Various psychiatric symptoms are seen after strokes which are usually deserted due to poor familiarity about it, hence better knowledge and understanding of various post stroke psychiatric manifestations may help in early identification and management of it. The aim of present research is to study the demographic and clinical profile of various post stroke psychiatric manifestations.Methods: The study was conducted on ninety patients developing psychiatric symptoms after stroke. Detailed socio-demographic characteristics, clinical profile along with psychiatric assessment were recorded in proforma specially designed for the study.Results: Bulk of this post- stroke psychiatric subjects (45%) was in the age range of 61-80 years of which male and female were 29% and 16% respectively.  Most of patients (90%) were residing at rural areas. 47.8 % patients were belonging to lower middle socio-economic status.  Majority of subjects (42.8%) were unemployed followed by farmer and skilled worker (20% each), and most of the patients were right handed (97.8%). On clinical parameters maximum subjects (52.2) developed post stroke major depression followed by depression mixed with anxiety (16.6%). Rest of patients suffered from organic anxiety disorder (8.8%), vascular dementia (10%), amnestic syndrome (5.5%), post stroke psychosis (3.3%), organic manic disorder (2.2%), pathological laughter and crying (1.1%).Conclusions: Huge number of patients (52.9%) developed psychiatric problems of diverse nature among patients with stroke syndrome. depression was most common post stroke psychiatric manifestation, followed by mixed anxiety with depression.  Generally the post stroke psychiatric manifestations are unrecognized and untreated, which has adverse impact on process of stroke rehabilitation. Thus a detailed psychiatric evaluation is mandatory in all patients of stroke syndrome to rule out psychiatric illness.
