An approach to the organizational strategic decision-moment in new product development
Authors: Hernández Betancur Juan-Esteban , Montoya Luz Alexandra , Montoya Restrepo Iván
Published: September 2022

Purpose: To explain the strategic decision-moment behaviour from an organizational approach, particularly from the cross-functional integration in new product development processing. Design: The methodology is focused on agent-based simulation, particularly using NetLogo software. Virtual experiments were developed to identify the effect of the agents interactions with each other and with the environment. Results: The presence of prior information and the disposition of the interaction meetings among departments in the cross-functional integration processes have a decreasing impact on the number of steps required to reach an agreement, but the number of necessary decisional interactions is not affected. Limitations: The comprehension of the decision-moment that is made within this research process is focused on the organizational approach to the development of new products. It is interesting to contrast the results with other organizational approaches and with studies on real cases. Originality: Application of agentbased simulation on the functional understanding of the strategic decision-moment in the organizational context.
Aesthetic heuristics for design: perceptual and absolute standards of beauty determinants
Authors: Ruiz Córdoba Stefany , Maya Jorge
Published: September 2022

The extraction and formalization of design heuristics used in design is an increasingly important area of research because of their multiple possibilities of application, especially for design practitioners. However, most of the attention has been paid to design heuristics for designing the product's functionality, usability, or architecture, three design tasks where plenty of methods are already successfully used. On the contrary, aesthetic design is an area where intuition is the prevalent method used to seek the generation of aesthetic pleasure for the user. Some methods exist but they are rather of descriptive nature, stating what to do, but without explaining how to do it. To tackle this problem, this paper describes a method to extract and validate a set of 223aesthetic design heuristics obtained from textbooks and scientific literature. These heuristics were validated through the analysis of 50 products winners of design awards; 123 were coincident and 36 new. Out of the 123, 46 heuristics were randomly selected and validated by analyzing the interrater agreement of an experts' survey (n=24). Eighteen aesthetic design heuristics resulted in potentially increasing the users' aesthetic pleasure.

Published: September 2022

In response to the enormous amounts of coal discard generated during coal mining and preparation, the development of an efficient and sustainable strategic use of this resource is essential. Furthermore, the rising urban population over the next decades is confronted with the depletion of quality raw materials for building components. To this end, this study reports new information on the morphology, water absorption, and flexural strength properties of ceramic composites produced from three different coal discards and polysiloxane pre-ceramic polymer (PCP) resin. In addition, test results relating to the continuous operating temperature, chemical resistance, and efflorescence potential of the composites are presented. The results show that the water absorption and flexural strength of the coal composites, up to 1.94% and 36.46 MPa respectively, exceed the requirements for ceramic and clay roof tiles. The continuous operating temperature of composites is found to be more thermally stable than conventional roofing tiles (concrete and ceramic) between ambient temperature and 600°C. In addition, the excellent chemical resistance of the composites (94.43%-99.98%) compared to conventional roofing tiles (67.82%-99.97%) eliminates the need for additional external coatings. The interesting results documented so far suggest that this technique could be used to produce low-temperature application building products such as bricks, panels, roofing tiles, etc. This new recycling technique offers an excellent opportunity to eliminate enormous volumes of coal discard and to advance the circular economy in the coal industry.

Authors: Desai Urvi , Ilieva Hirstelina , Peltier Amanda
Published: September 2022

Familial amyloid polyneuropathy is a rare autosomal dominant disorder caused by mutations in the transthyretin gene, TTR. More than 100 mutations in the TTR gene are known. p.Val30Met was identified first as a cause of FAP and is the most common mutation worldwide. p.Val30Met is associated with peripheral neuropathy while p.Val142lle (C.424G>A) (also known as p.Val122lle)  is associated with cardiac amyloidosis [1, 2, 3] . In this context, we report a patient harboring p.Val142lle mutation with exclusive small fiber neuropathy and absence of any cardiac involvement representing genotypic-phenotypic heterogenicity.

Authors: Luster Joshua D. , Jacobus II Brent , Sladky John , Fullam Timothy
Published: September 2022

Myasthenia Gravis is a disorder characterized by autoantibodies targeting different proteins across the neuromuscular junction. The typical presentation of Myasthenia Gravis involves oculobulbar weakness, classically ptosis that may or may not be symmetric. Patients may also present with a more dramatic presentation of generalized weakness or even in myasthenic crisis requiring respiratory support for oxygenation. While these are the common presentations, our patient, a 63 year old male, presented with an atypical presentation of what is described as Limb-Girdle Myasthenia Gravis. This patient presented with proximal arm and leg weakness that rapidly progressed and lead to loss of reflexes, appearing to be a myelopathy prior to obtaining an electromyography/nerve conduction study which demonstrated decrement of 21% in ulnar, 22% in median, and 59% of radial nerves during 2Hz repetitive stimulation. Our patient improved with plasmapheresis and prednisone with full recovery of strength.

Design and Fabrication of Soft 3D Printed Sensors and Performance Analysis of the Soft Sensors in a C-leg as Sensing Element
Authors: ÖZBEK Doğa , YILMAZ Talip Batuhan , KALIN Mert Ali İhsan , ÖZCAN Onur
Published: September 2022

In soft robotics, a recent challenge is to decrease the number of rigid components used tocreate entirely soft robots. A common rigid component used in soft robots is the rigid encoder, which should be replaced with a soft counterpart if possible. In this work, we de-sign and manufacture a soft sensor, which is embedded into a C-shaped leg of a soft, legged, miniature robot. Our main goal is to show that we can embed a soft sensor into and receive contact feedback from a soft C-shaped leg of our soft miniature quadruped. We test various sensor parameters using custom test setups to analyze the soft sensor performance. Our soft sensor design is iterated by experimentally investigating several sensor shape options. For the C-leg of the soft miniature quadruped, optimal sensor geometry and position for the sensor implementation are found from a discrete design space as the outcome of this work. We received feedback from the soft sensor and compared commercial encoder data to the soft sensor embedded C-leg data. We managed to detect the rotation speed of the C-leg with the accuracy of 87.5% on a treadmill and with the accuracy of %86.7 under free rotation of the C-leg. However, if connection loss occurs in the miniature slipring mechanism, the error percentage in estimating the rotational speed increases significantly.

Authors: ÖZTÜRK İbrahim İsmet , GÜRGAN ESER Muazzez
Published: September 2022

Bismuth, known as a heavy metal, is excluded from this class due to its low toxicity. Due to this feature, bismuth containing compounds have always been interesting compounds in the field of medicinal chemistry. For this reason, the discovery of new bismuth compounds and the investigation of their biological properties are very important for this field. In this study, three new bismuth(III) compounds formulated as [Bi(L)2X3] (L: 5-chloro-2-mercaptobenzothiazole (ClMBZT); X: Cl, Br, and I) were synthesized for the first time and, the molecular structure of them were elucidated by a series of spectroscopic techniques. Thermal stability and degradation steps of the title compounds were analyzed by Thermogravimetric-Differential Thermal Analysis (TG-DTA). The antibacterial study has been conducted against six strains bacteria, and the results indicated that bismuth(III) compounds generally showed more effective antibacterial activity than free ligand. The anti-inflammatory potential of bismuth(III) compounds was investigated through in vitro lipoxygenase enzyme inhibition studies. The results show that bismuth(III) compounds have higher anti-inflammatory potential than free ligand.
Epistemic Turbulence in Renewable Energy Engineering on the Chinese “Belt and Road”
Authors: Chen Zhuo , Tilt Bryan , Zhang Shaozeng
Published: September 2022

Energy issues constitute a nexus of technological, political and economic challenges, particularly in light of the global climate crisis. Chinese banks and corporations, guided by a multi-trillion dollar infrastructure investment program called the “Belt and Road Initiative,” now account for one-third of global investment in renewable energy. In this ethnographic study, we explore the professional knowledge and practices of Chinese, Israeli and European engineers working on a pumped-storage hydropower project in Israel with financial and technical backing from Chinese energy firms. We examine how these experts construct and maintain a set of epistemic cultural practices within transnational flows of capital, technology, materials and expertise. Situating our findings within Science and Technology Studies (STS), we use the hydrological engineering concept of “turbulence” as a metaphor for the rapid transnational movements of engineering concepts and personnel in the renewable energy sector.
Ethics of Emerging Technologies: An Interview with Geoffrey C. Bowker
Authors: Nas Elen
Published: September 2022

The challenges of research in ethics and technology require attentive listening. Geoffrey Charles Bowker, began to give attention to the theme over twenty years ago. What ensues is a contemporary commentary on the ethics of emerging technologies with extracts from an audio interview (by Zoom) between Elen Nas and Bowker, which took place during the early part of the Covid-19 pandemic. The main question of this open dialogue is regarding the use of technologies such as AI to ask—what has changed with the problems identified now and in the past in relation to ethical computing? To paraphrase Bowker—it is impossible to think of new technologies that would not change human values then and now.

Published: September 2022

O ensino-aprendizagem de línguas pode contribuir tanto para a manutenção de hierarquizações e apagamentos ideológicos quanto para a promoção de espaços acolhedores e problematizadores. Mesmo assim, a produção de materiais didáticos que contribuam para que as subjetividades e os saberes indígenas penetrem os muros das instituições educacionais pode ser considerado um processo capaz de contribuir para a união de forças e movimentos sociais articulados, dirigidos à mudar essa realidade. Partindo desse pressuposto, neste artigo, visamos analisar como os povos originários e as literaturas indígenas foram abordados num volume da coleção pedagógica intitulada Rotas de Educação Crítica para Docentes do Inglês. Ainda mais, avaliamos o potencial de suleamento da educaçâo em línguas e aprofondamos no análisis das noções de língua(gem), identidades e literaturas que informam o material. Ainda, avaliamos a profundidade das discussões propostas e a possível (re)produção de repertórios pejorativos e narrativas únicas sobre os povos originários. Entendemos que o material tem uma proposta inovadora, com possibilidade de contribuir para a formação docente engajada socialmente e atenta a diferentes identidades, saberes, culturas e epistemologias. Assim, apontamos que, embora o material não tenha sido concebido na base de propostas decoloniais, ele constitui-se como uma resposta do Sul dedicada à formação docente empenhada em promover um olhar crítico e engajado nas questões sociais. As implicações de propostas como essa são a ampliação de movimentos de identificação, denúncia e interrupção de hierarquizações, invisibilidades e inviabilidades da colonialidade que nos constitui, contribuindo assim para a construção de realidades outras.

Published: September 2022

Esta investigación cualitativa permitió analizar y describir la naturaleza de las revelaciones en notas a los estados financieros anuales del 2019 e intermedios del 2020, en empresas chilenas y peruanas cotizadas en el contexto de pandemia por COVID-19, bajo el marco de la teoría institucional. Los resultados del estudio confirman que el nivel de revelación sobre el impacto de la COVID-19 no cumple con todos los criterios de la normativa y recomendaciones a pesar de la influencia institucional de entes reguladores y firmas de auditoría. Si bien, algunas empresas revelan información sobre efectos financieros, un gran grupo no ha sido capaz de cuantificarlos y ha terminado afectando el cumplimiento del objetivo de la información financiera según NIIF de utilidad para la toma de decisiones. Esto ha llevado a encontrar una influencia institucional mimética o normativa de efectivo cumplimiento de las NIIF o recomendaciones de firmas de auditoría.

Published: September 2022

Aim: to study the factors leading to adverse perinatal outcomes allowing, on this basis, to predict degree of perinatal risk.

Materials and Methods. The medical records of 155 patients who performed delivery in 2019–2021 were retrospectively analyzed. The following groups were formed: main group included 56 patients with adverse perinatal outcomes (9 fetuses died antenatally, 36 fetuses born below Apgar score 5, 9 newborns died within the first 168 hours of extrauterine life, 2 infant deaths). The control group included 99 patients with favorable perinatal outcomes. While assessing the data retrieved from medical records, sociobiological and laboratory-instrumental indicators, obstetric-gynecological and somatic anamnesis, the presence of extragenital pathology, the delivery process, information related to child condition at the time of birth and in early neonatal period were analyzed.

Results. In patients of the main group, significant differences were revealed compared to control group, respectively: high parity (3 or more deliveries) – 11 (19.6 %) and 15 (15.1 %) (p = 0.001); vomiting of pregnant women in early gestation – 27 (48.2 %) and 14 (14.1 %) (p = 0.005); the presence of uterine scar after two or more caesarean sections – 7 (12.5 %) and 2 (2.1 %) (p = 0.009); former abortions – 24 (42.8 %) and 16 (16.1 %) (p = 0.0017); acute respiratory viral infection in the first trimester – 21 (37.5 %) and 13 (13.1 %) (p = 0.005); threatened abortion in the second trimester – 23 (41.0 %) and 15 (15.1 %) (p = 0.0005); Doppler-based blood flow disorders in the second trimester – 17 (30.3 %) and 11 (11.1 %) (p = 0.008) and in the third trimester – 9 (16.0 %) and 3 (3.0 %) (p = 0.006); altered amniotic fluid index according to ultrasound data in the second trimester – 6 (10.7 %) and 1 (1.0 %) (p = 0.011); intrauterine growth retardation in the third trimester – 15 (26.7 %) and 4 (4.0 %) (p = 0.012); severe preeclampsia – 6 (10.7 %) and 1 (1.0 %) (p = 0.04). In patients of the main group, pregnancy was finished prematurely in 41.1 % of cases compared to 100% term delivery in control group.

Conclusion. The risk factors identified, which were manifested in the first and second trimesters of pregnancy may be predictors for adverse perinatal outcomes. Based on the study results for patients of the main and control groups, it was convinced that the topic of predicting favorable and unfavorable perinatal outcome is currently far from being disclosed, which is a long meticulous path of search, analysis and comparison.

Published: September 2022

Background/Aim: The profile of patients with hepatocellular carcinoma (HCC) has changed globally; the role of etiology in predicting prognosis of HCC patients remains unclear. We aimed to analyze the characteristics and prognosis of Korean patients with HCC according to disease etiology.Methods: This retrospective observational study included patients diagnosed with HCC between 2010 and 2014 in a single center in Korea. Patients with HCC aged <19 years old, had coinfection with other viral hepatitis, had missing follow-up data, were Barcelona Clinic Liver Cancer stage D, or died before 1 month were excluded.Results: A total of 1,595 patients with HCC were analyzed; they were classified into the hepatitis B virus (HBV) group (1,183 [74.2%]), hepatitis C virus (HCV) group (146 [9.2%]), and non-B non-C (NBNC) group (266 [16.7%]). The median overall survival of all patients was 74 months. The survival rates at 1, 3, and 5 years were 78.8%, 62.0% and 54.9% in the HBV group; 86.0%, 64.0%, and 48.6% in the HCV group; and 78.4%, 56.5%, and 45.9% in the NBNC group, respectively. NBNC-HCC has a poorer prognosis than other causes of HCC. Survival was significantly longer in the HBV group with early-stage HCC than in the NBNC group. Furthermore, survival was shorter in patients with early-stage HCC and diabetes mellitus (DM) than in those without DM.Conclusions: The etiology of HCC affected clinical characteristics and prognosis to some extent. NBNC-HCC patients showed shorter overall survival than viral-related HCC patients. Additionally, the presence of DM is an additional important prognostic factor in patients with early-stage HCC.
Polyphenols of Artichoke Fractions and Their In-Vitro Digestion
Authors: TÜRKMEN EROL Nihal
Published: September 2022

This study was aimed to determine total polyphenols (TP), total flavonoids (TF), chlorogenic acid (CA), antioxidant capacity (AC) and in-vitro bioaccessibility of polyphenols (as gastric and intestinal stages) of the extracts from artichoke fractions (head, bract and stalk) using different solvents (80% ethanol, 80% methanol and water). The results showed that artichoke fraction and solvent used significantly affected all parameters measured (P<0.05). TP and TF contents of the samples varied in the range of 1.74-5.52 mg gallic acid equivalents per gram of dry matter (mg GAE g-1 DM) and 1.30-7.34 mg rutin equivalents per gram of dry matter (mg RE g-1 DM), respectively. AC of the samples varied from 433.73 to 1243.21 mmol of ascorbic acid equivalents per 100g of dry matter (mmol AAE 100g-1 DM).TP and AC of the extracts varied depending on artichoke fraction and solvent used after in-vitro digestion. They were found to be lower than their initial (before digestion) values. Bioaccessibility of the polyphenols was in the range of 17.36-64.37%. CA detected in all extracts except water extracts of artichoke head (AH) and artichoke stalk (AS). These results suggest that artichoke bract (AB) and AS which are artichoke byproducts might represent a potential source of natural antioxidants as well as AH.

Authors: Hossain Md. Solaiman
Published: September 2022

This study aims to investigate the impact of different parts of the disclosure index on concerned components of investors’ decisions. For this consideration, this study has constructed an unweighted disclosure index under eight headings: corporate profile items, corporate governance items, employees and social responsibility items, risk management items, indicators of financial performance, income statement items, balance sheet items, and accounting policy items. The individual disclosure of each part of the disclosure index has been calculated. This study also identified some concerning components of investors' decisions like current ratio, working capital ratio, deposit assets ratio, cash deposit ratio, return on equity, return on assets, dividend yield ratio, and dividend payout ratio. To achieve the study objective, this study has used secondary data extracted from published audited annual reports of ten sample banks in Bangladesh from 2015 to 2019. The ANOVA test and multiple regression analysis with the ordinary least square model (OLS) have been employed to reveal the study findings. The results of the ANOVA test report significant variation in the disclosure scores of different parts of the disclosure index and the various concerned components of investors’ decisions. The results of multiple regression analysis illustrated that the disclosure scores of the other parts of the disclosure index had a significant positive impact on the different concerned components of investors’ decisions.

Authors: Jallouli Rim , Kaabi Safa
Published: September 2022

The increasing use of e-commerce technologies has been studied in several fields and from different perspectives: technological, economic, organizational and social: hence, the need for a literature review that provides a map of top strategic e-commerce technologies from a managerial perspective and, more specifically, for digital marketing research. This paper aims to provide researchers with a comprehensive overview of the range of e-commerce technologies that have had a significant role in shaping digital marketing strategies. Based on a thematic analysis, e-commerce technologies were classified through eleven categories. The objective is to reveal how each set of technologies affected the different digital marketing strategies. Both descriptive and clustering analyses show that the most evoked technologies in the digital marketing literature are Information and Communication Technologies and platforms. Results outline the growing interest in artificial intelligence technologies. Moreover, this literature review reveals how digital marketing research has focused on technology-enabled segmentation and targeting strategies, along with the use of social platforms and the development of new products and services. The scarcity of marketing papers studying the impact of cloud technologies, IoT, blockchain and data analytics orient researchers towards exploring further the potential of these technologies for digital strategies.

Authors: Shahria Golam
Published: September 2022

Research aims: The primary aim of this study is to examine the effect of the COVID-19 pandemic during and after this pandemic on manufacturing sectors in Bangladesh. In the context mentioned above, some issues are then taken as the specific objectives.Design/Methodology/Approach: The study was conducted on the manufacturing sectors listed under Dhaka Stock Exchange (DSE). The study's target population was 42 manufacturing companies out of 153 listed on Dhaka Stock Exchange (DSE). Four research variables were used to evaluate sample companies' financial performance and financial position. Documentary analysis, descriptive analysis, data normality test, and Wilcoxon Signed–Rank Test were employed to evaluate the hypotheses. The years of annual reports, 2018-2019 to 2020-2021, were utilized for the documentary analysis of sample companies' financial performance and financial position.Research findings: The study's conclusions demonstrated that this pandemic significantly impacted Bangladeshi companies' financial performance (essentially ROA and ROE) at a 5% significance level compared to before the pandemic. In addition, the recovery growth rate of financial performance of sample companies increased optimistically, and the growth of liquidity position of manufacturing companies was also seen in an advantageous position after the COVID-19 pandemic compared to during the COVID-19 pandemic based on Wilcoxon statistical test tool.Theoretical contribution/Originality: The findings of this study can be used as a source of relevant data by investors or future investors for their investment decisions shortly. The findings of this study will also assist the government in determining or preparing the appropriate tax incentive scheme for the impacted industries and whether the correct sector would profit from the tax incentive scheme.Practitioner/Policy implication: Considering that the COVID-19 pandemic has significantly impacted the import process of raw materials for production from China in specific and from other countries generally, the study advised the government of Bangladesh to boost its logistic and financial support for the local facility of raw materials.Research limitation/Implication: More extensive research is projected to be conducted on the recovery growth rate of financial performance in Bangladesh's sub-sector manufacturing industries.

Background: Objective of the study was to evaluate the effects of vicrylrapide (VR) (polyglactin 910) and chromic catgut (CC) for episiotomy repair.Methods: A prospective, randomized, comparative study carried over a period of one year. 200 women were included in the study after taking informed consent and randomly allocated to repair with VR group and CC group (100 each). The outcome measures were assessed in terms of postpartum perineal pain, nature of wound healing, need for resuturing and resumption of sexual activity and dyspareunia at 24-hour, 7th day, 6th week and 12th week postpartum.Results: The mean age was 24.39±2.95 (range: 19-31 years) for VR and 24.38±3.80 (range: 18-37 years) for CC group. The VR group was associated with less severe pain (31%) compared with CC group (74%) indicating higher pain intensity in CC group. There was also a significant difference in the uncomfortable stitches, urinary retention, defecation difficulty, wound indurations, and wound dehiscence (0% versus 7%) and a better wound healing (p=0.004) in the VR group. Insignificant statistical difference was noted at 6 weeks and 12 weeks (p=0.786 and 0.627) between two groups in terms of dyspareunia.Conclusions: VR is an ideal suture material for episiotomy repair compared to CC as it is associated with less perineal pain, less uncomfortable sutures and a better wound healing.

Background: Cancer cervix is in the top rank of gynecological cancers in the developing countries cervical cancer has a long latent period and can be prevented by simple treatment of cervical intraepithelial neoplasm. The incidence of invasive cancer can be decreased by early detection of preinvasive stage which can be treated at the same sitting, “see & treat approach” strategy. Objectives were to estimate the strength of correlation in detecting preinvasive lesions of cervix between colposcopy and directed biopsy and to correlate various socio-demographic data with cervical pre-invasive and invasive lesion. To compare the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of colposcopy with colposcopic directed biopsy.Methods: On selecting the patients based on the criteria, per speculum examination was done and in the presence of abnormal cervix, advised for PAP smear. Based on PAP smear scaled according to Bethedsa staging, patients were accordingly advised for colposcopy. Reid’s colposcopic index applied and biopsy was taken over the site with highest score and sent for HPE in a labelled bottle with fixative.Results: Colposcopy when compared to histopathology had a sensitivity of 100 %, specificity of 48.3%, with PPV of 22.4 % and NPV of 100 %. The p value was 0.001 suggesting a significant strength of agreement between colposcopic diagnosis using Reid’s index and histopathological diagnosis.Conclusions: Correlation of colposcopic impression with directed biopsy is described as the reference investigation or ‘gold standard’ for the diagnosis of cervical precancerous lesions.

Published: September 2022

Background: Aim was to evaluate the differences in platelet count and platelet indices between pregnant women with gestational diabetes mellitus (GDM) and apparently healthy pregnant women.Methods: A cross-sectional study was performed with 68 pregnant women with GDM (cases) and 68 apparently healthy pregnant women (controls) after 24 weeks of gestation. The study groups were compared in terms of demographic, clinical and laboratory characteristics including platelet count and platelet indices.Results: Mean platelet volume (MPV) (p=0.002*) and platelet distribution width (PDW) (p=0.010*) were significantly increased in pregnant women with GDM compared to the apparent healthy pregnant women (p<0.05). MPV was well correlated with PDW (p=0.00). Conclusions: The platelet indices on CBC testing can aid in identification of GDM, and can help to prevent various complications associated with GDM. The clinical relevance of these platelet indices needs further studies.

Background: Postpartum haemorrhage is the most important cause of maternal mortality which is near about 13% in developed countries and 34% in developing countries. When postpartum haemorrhage is not controlled even after aggressive medical management, immediate surgical intervention is needed which includes bilateral internal iliac artery ligation, B-Lynch compression sutures, hysterectomy as a last resort. Bilateral internal iliac artery ligation is much quicker and having lesser risk of uterine necrosis as compare to B-Lynch suture. That’s why a study was conducted to evaluate and compare the role of bilateral internal iliac artery ligation with B-Lynch compression sutures.Methods: A prospective observational study was conducted in the department of obstetrics and gynaecology in Burdwan medical college and hospital for a period of 3 years from 1st July 2019 to 30th June 2022. Out of total 62 cases of intractable postpartum haemorrhage, 31 cases underwent bilateral internal iliac artery ligation (group A) and another 31 cases underwent B-Lynch compression sutures (group B).Results: In this study, most of the women were in the age group of 21-30 years. both in group A and group B. Risk factors for postpartum haemorrhage in both groups were pre-eclampsia, abruption, placenta previa, nonprogress of labour, multiple pregnancy. Blood products requirements were much more in group B than group A. Hysterectomy needed in 12.9% cases of group A and 29.03% cases of group B. In terms of maternal outcome, out of total maternal death, 37.5% cases were under group A, 62.5% cases were under group B.Conclusions: In our study, need for hysterectomy was less in cases of bilateral internal iliac artery ligation compared with B-Lynch compression sutures. So, bilateral internal iliac artery ligation should be early resort to prevent hysterectomy in cases of atonic postpartum haemorrhage with low parity. As bilateral internal iliac artery ligation is a life saving procedure, every obstetrician must be able to perform it and should have proper knowledge of retroperitoneal anatomy to avoid injury of iliac veins and ureter.

Background: Development of pre-eclampsia (PE) at less than 34 weeks of gestation is known as early onset PE (EOPE) and is commonly associated with more severe adverse maternal and fetal outcomes. The purpose of this study was to study Doppler parameters of uterine, umbilical and fetal middle cerebral arteries exclusively in women with EOPE and its correlation with perinatal outcomes. This study was a hospital-based observational prospective study.Methods: 60 patient of early onset PE with singleton live pregnancy were included in the study and followed up. The results of sonographic and Doppler examination were analysed and correlated with perinatal outcomes.Results: Adverse perinatal outcomes were seen in 66.66% cases of early onset PE. To predict adverse perinatal outcomes, umbilical artery (Umb A) RI, PI were found to be most sensitive, cerebroplacental ratio (CPR) was most specific indicator with highest positive predictive value (PPV). Absent end diastolic flow /reverse end diastolic flow (AEDF/REDF) were ominous signs.Conclusions: Early onset PE is recently considered a more severe disease with different etiopathogenesis. Doppler study is the primary imaging modality for fetomaternal surveillance for follow up and prediction of perinatal outcome, thus allowing planning of timely management in early onset PE patients, as these patients are at higher risk of adverse perinatal outcomes.

Pre-implantation genetic testing (PGT) is an advanced form of prenatal genetic testing that is done as a part of ART cycles. The purpose of PGT is to identify genetically normal embryos in a given cohort, in order to select the most desirable embryos for implantation. With the gaining popularity of day 5 trophectoderms biopsy over day 3 blastomere biopsy, the role of PGT has become more clinically significant. To report the data of 13 couples, with diagnosed genetic condition and having risk of transmitting this condition to their offspring’s, who underwent Pre-implantation genetic diagnostics (PGT M/SR). PGT was performed in 13 couples with various rare chromosomal conditions like Hereditary Inclusion body myopathy, Col4a1 gene mutation etc at our Infertility Centre from January 2016 to January 2020. The clinical data of all these patients was reviewed and is reported in our study. A total of 193 oocytes were retrieved and 158 oocytes were fertilized by ICSI. 62 blastocysts were obtained and 55 blastocysts were biopsied for analysis. Among the 35 normal embryos, 17 embryos were transferred. 11 clinical pregnancies were established resulting in 8, disease free, live births. PGT (M/SR) is an effective molecular diagnostic test, that is a ray of hope for many genetically affected couples, as its prevents the transmission of their unwanted genetic condition to their offspring’s.

Genital prolapse is one of the most common disorder affecting women of varying age group; though it typically affects older and parous women. Malfunction of the pelvic support is the most common cause of this disorder. Increasing age and excess weight are established risk factors for pelvic organ prolapse.In young nulliparous women conservative surgery is preferred to preserve the fertility of the patient. The approach of surgery can be either vaginal or abdominal depending on the classification of prolapse. We reported a rare case of a 36-year-old P1L0 (IUFD1) A1 with cervical elongation who was apprehensive to have a child. She was managed at our institute and had a successful pregnancy outcome in spite of undergoing embolization for secondary haemorrhage following modified Manchester-Fothergill operation.

Sirenomelia is a rare congenital anomaly with an incidence of 0.8 to 1 case per 1,00,000 births. The prognosis is grim due to associated genitourinary and gastrointestinal anomalies. Antenatal registration in the first trimester and timely ultrasound go a long way in detection of the anamoly when termination can be still be offered and the mental agony of giving birth to a term neonate with a fatal congenital anomaly can be avoided.
