Authors: RAVICHANDRAN SUBRAMANIAN , VENGATESAN E. , RAMAKRISHNAN A.
Published: April 2019

Composite materials are replacing traditional materials, because of their superior physical and mechanical properties. The main objective of the present work is to perform stress-strain analysis on Styrene-Ethylene-Butylene-Styrene (SEBS)-epoxy resin composites under reinforcement of fibres and dispersion of CuO, ZnO, MgO, SiO and TiO2nano metal oxides. Combination of glass fibre with particle reinforcement (GFRPs) applications has increased in recent days. In this study, glass fibre reinforced epoxy composites with different nano metal oxides are developed by compression moulding method and their mechanical properties such as breaking load, elastic limit, plastic range and fracture point are evaluated. The results indicate that the incorporation of nanophase material with glass fibre can improve the properties of composites.

Temperature Effect in Adsorption of Blue HE-3R on Calendula officinalis: Isotherm, Kinetics and Thermodynamics
Authors: RAMAN M.K. , MUTHURAMAN G.
Published: April 2019

Adsorption of a textile reactive dye blue HE-3R was carried out with a low-cost adsorbent material i.e., Calendula officinalis. The batch adsorption experiment was done with respect to the effect of pH, concentration of dyes, adsorbent dose and contact time. All the experimental results were analyzed for the suitability of Isotherm models (Freundlich, Langmuir, Redlich-Peterson and Tempkin) and kinetic models (pseudo-first-order, pseudo-second-order, intra-particle diffusion and Elovich). Adsorption process follows Redlich-Peterson isotherm and Pseudo-second order kinetics. The maximum adsorption quantity was found to be 17.85 mg g-1 for the adsorption of blue HE-3R on Calendula officinalis. The low temperature favours the adsorption process. The difference in the SEM image and changes in the group frequencies in FT-IR spectra supports the adsorption of Blue HE-3R on Calendula officinalis effectively.

“It’s like fifty-fifty”: Using the Student Voice towards Enhancing Undergraduates’ Engagement with Online Feedback Provision
Authors: Hast Michael , Healy Caroline
Published: April 2019

Reflecting the continuing change in higher education student experiences in light of the electronic age it is crucial to examine whether digital feedback provision approaches are seen as helpful in promoting self-regulated learning. In the present study students (N = 99) completed a survey examining preferences and gathering initial qualitative data. A sub-set (N = 18) took part in focus groups. In line with trends observed in previous research, a high proportion of students preferred submitting work and accessing feedback online. Attitudes towards the shift from hard copy to online feedback provision were largely positive, focusing on improved aspects of spatial and temporal distance. However, the student insight also highlighted concerns around communication and motivation to engage with feedback, indicating there is a need for appropriate training to support the access to feedback and how to engage in post-feedback communication beyond the computer screen.

Authors: Rojas Luis Ricardo , Rueda Varon Jenifer
Published: April 2019

Bilingual indigenous students who attend public schools around the country are to develop English language skills as part of the suggested curriculum created by the Colombian Ministry of Education. This is the case of the Embera Chamí students in Florencia, Caquetá whose conditions for learning English differ from those of monolingual Spanish students. The purpose of this study is to analyze the difficulties and the advantages of learning English through task- and project-based learning in bilingual indigenous students. The analysis of the study was developed through the method of systematization of experience. Results suggest that the two learning approaches enhanced indigenous students’ speaking skills and facilitated vocabulary recognition. However, the students mentioned being more interesting in learning English for specific purposes.
Effect of nitrogen application on the phytochemical production in Jatropha curcas L. (Angiosperms: Euphorbiaceae) during drought conditions
Authors: Adebusola Adewole , Victor Odjegba , Emmanuel Iwuala , Alam Afroz
Published: April 2019

Nitrogen is an important nutrient for the successful metabolism of plants, but its occurrence in soil is always very limited. This nutrient has a significant role to preserve plants during various stress conditions by altering the production rate of phytochemicals as defense weapons. Hence, this study was carried out to analyze the effect of nitrogen supply on the phytochemical composition and relative water content in Jatropha curcas L. under a simulated drought condition. The selected seedlings were grown from stem cuttings and categorized into different treated three groups along with the control. After the completion of the experiment, the growth pattern and phytochemical production were investigated. An increased malondialdehyde activity (MDA) was reported with a reduction in relative water content (RWC) of the leaf and in the biomass of seedlings under drought stress. A significant decrease in the levels of alkaloids, phenol, flavonoids and tannins with an increase in saponins and terpenoids was also observed in only simulated drought stressed plants. While a significant increase in the levels of total alkaloid, tannins, flavonoids and phenols was observed in those plants where exogenous nitrogen was supplied before the start of drought periods, unlike in treated and control plants. Therefore, it was revealed that application of Nitrogen enabled the plants to possess protective mechanism through the production of phytochemicals that facilitate the cell membrane to reduce the detrimental effects caused by drought stress.
COGNITIVE AND AFFECTIVE DIMENSIONS OF FOREIGN LANGUAGE LEARNING ENVIRONMENTS: A POLISH-TURKISH COMPARATIVE STUDY
Authors: Gabryś-Barker Danuta
Published: April 2019

The term learning environment is a construct perceived by researchers as embracing different aspects of the teaching-learning continuum. It can be described as the physical location where learning occurs: learning in class versus learning beyond it, learning in a home country (with focus on the effects of a learning environment on outcomes of teaching) versus learning abroad (Dewey, 2004, Diaz-Campos, 2004), the latter constituting a fast-growing area of study. Learning environment also means the physical space where formal instruction is carried out (Gabryś-Barker, 2010). But above all, learning environment studies focus on interactions between adults (teachers, parents) and students and show how these relations can affect the latter’s achievement and more generally well-being at school and outside. Thus, it can be seen as mostly affective. This chapter aims to comment on the perceptions pre-service teachers have of a foreign language learning environment, as expressed in their narrative texts on the topic. The data obtained in this study will be compared with the result of a similar study carried out with a group of pre-service EFL teachers in a different cultural setting, in Turkey (Sağlam, Sali, 2013). This should shed some light on whether the trainees’ perceptions are in some way culture-specific and therefore grounded in the educational policies of a given country. The conclusions drawn from the study will hopefully contribute to the ongoing discussion on how to improve FL teachers’ training programmes.
LANGUAGES AND THE SELF
Authors: Komorowska Hanna
Published: April 2019

The article looks into the meaning of concepts of L2 Self, L2 Ideal self and L2 Motivational Self Systems from the point of view of their usefulness for SLA/FLT research. Psychological and sociological terminology related to the Self, Identity, Storied Self, Social Identity and Ethnicity is then discussed as well as various types of the Self useful in the analysis of attitudes to first, second and foreign languages. Examples of linguistic decisions are offered that lead to language maintenance, language loss or changes of the dominant language. Linguistic behaviour is traced back to possible ways of presenting the Self as well as to different approaches to ethnicity, integration and assimilation. Conclusions and implications for classroom language learning and teacher education are also presented.

Published: April 2019

There is much controversy surrounding the influence of affect on foreign language aptitude. In most foreign language aptitude models and tests this factor is treated marginally or it is entirely absent. In research studies, much attention is devoted to individual factors defined in the context of positive psychology, but their relationships with cognitive factors are rarely analyzed. This paper is an attempt to present the role of factors other than cognitive in foreign language aptitude theory and research, selected reasons for their weak position, as well as pedagogical implications and suggestions for further research.
ROLA MOTYWACJI W PROCESIE UCZENIA SIĘ JĘZYKA PRZEZ UCZNIÓW Z DOŚWIADCZENIEM MIGRACJI – METODA JES-PL
Authors: Pamuła-Behrens Małgorzata , Morena Katarzyna
Published: April 2019

An increasing number of immigrant students pose new challenges for the Polish school. The immigrant groups consist of foreign children, but also Polish children who migrate with their parents. Their adaptation to a new place and integration are not always easy. These children do not only need professional support from the school and its staff, but also from Polish students. The key to succeeding in this complex process is to learn the language and culture of the country of settlement. Acquisition of this knowledge is conditioned by a motivation to face the Other, the language and culture. The purpose of the paper is to explore the role of motivation to learn the new language and culture of the country of settlement. In particular, we focus on determinants of motivation in the context of language learning and problems immigrant and refugee students are faced with in a new country. We also present the JES-PL Method which aims to support the development of language and communication skills within an immigrant family in the context of school language education (JES).
Unique brain regions involved in positive versus negative emotional modulation of pain
Authors: Kornelsen Jennifer , McIver Theresa A. , Stroman Patrick W.
Published: April 2019

Background and aims

Research has shown that negative emotions increase perceived pain whereas positive emotions reduce pain. Here we aim to investigate the neural mechanisms underlying this phenomenon.

Methods

While undergoing functional magnetic resonance imaging of the brain, 20 healthy adult females were presented with negative, neutral, and positive emotion-evoking visual stimuli in combination with the presentation of a noxious thermal stimulus to the hand. Participants rated the intensity and unpleasantness of the noxious thermal stimulus during each of the valence conditions. General linear model analyses were performed on the imaging data for each valence condition and specific contrasts were run.

Results

Significant differences were detected for the emotional modulation of pain (EMP) between the positive and negative conditions. Unique to the positive condition, there was increased activity in the inferior parietal, parahippocampal/perirhinal, precuneus/superior parietal, and the prefrontal cortices. Unique to the negative condition, there was increased activity in anterior and posterior cingulate and angular gyrus.

Conclusions

Positive and negative EMP appear to involve different brain regions.

Implications

Although there is some overlap in the brain regions involved in the positive and negative EMP, brain regions unique to each condition are identified and, moreover, the regions identified are involved in internal and external focus, respectively, pointing to a potential mechanism underlying this phenomenon.
Clothing pressure alters brain wave activity in the occipital and parietal lobes
Authors: Liu Yunjuan , Wang Yan
Published: April 2019

Despite the importance of clothing pressure discomfort in the undergarment industry, a reliable unbiased measurement of clothing pressure discomfort has not been well-established. In the present study, we investigate changes in brain wave activity as a potential objective and consistent measuring tool for clothing pressure discomfort. We recorded α wave activity in 5 functional regions (30 channels) of the brain in 10 females with or without a girdle. We determined that α wave power spectrum significantly increases when the girdle is worn compared to when it is not worn, specifically in the parietal and occipital regions. These findings suggest that clothing pressure exerted by wearing a girdle mostly stimulates the parietal and occipital regions and that these regions should be investigated in future studies using α wave energy to measure clothing pressure discomfort.
Digital image recognition based on improved cognitive neural network
Authors: Liu Yuxi
Published: April 2019

This paper presents an innovative cognitive neural network method application in digital image recognition. The following conclusion can be drawn. Each point of the graph is transformed, and the original color of the transformed new coordinates is given to the point. If after all the points have transformed, if there is a point and no point has converted to this point, the point is not given a color. Then this point will form a hole or a stripe, and the color is the color of the point initialization. The innovative method can effectively separate the digital image recognition signal from the mixed signal and maintain the waveform of the source signal with high accuracy, thus laying the foundation for the next step of recognition.

Why Kant is a Weak Conceptualist
Authors: Baranovas Ruslanas
Published: April 2019

[full article, abstract in English; abstract in Lithuanian] The question whether Kant is a conceptualist has attracted significant attention of Kant scholars in recent decades. I present all three dominant positions in the debate (strong conceptualism, weak conceptualism, nonconceptualism) and argue that strong conceptualism and nonconceptualism are less plausible interpretations of Kant’s philosophy. I argue that the first cannot explain Kant’s commitments related to the incongruents, animals, and infants. The second one, meanwhile, cannot explain Kant’s argument on causation against Hume. At the end of the paper, I try to show that the key to a plausible and convincing interpretation of Kant as a weak conceptualist is the distinction between categories and empirical concepts.
A művi abortusz a férfi partner szemszögéből
Authors: Nagy Beáta Magda , Rigó Adrien
Published: April 2019

Abstract:

Induced abortion is an intervention that scientific research primarily addresses from the concerned women’s point of view in terms of either the causes or the consequences of the abortion decision. Nevertheless, each case of abortion involves a man as much as a woman (in the same vein as conception), which calls for the better knowledge of male partners’ needs, expectations and experiences related to induced abortion. The present summary addresses male partners’ status and importance in abortion care in a practical approach based on professional considerations. Available empirical findings suggest that male partners’ involvement in abortion care has importance both in protecting men’s emotional balance and in providing support for women in adapting to the abortion process. Male partners’ deeper involvement possibly includes roles such as seeing the female partner to the intervention, participation in pre-abortion counselling, presence during the intervention, and participation in post-abortion care. Related findings show that all of these forms of support are related to women’s positive abortion-related experiences and thus to their better recovery (provided that the female partner expresses a need for her male partner’s personal support). Furthermore, male partners’ involvement in abortion care enables health care providers to tailor counselling (information on the intervention, on possible consequences, on contraceptive methods etc.) to men’s specific needs. These practices facilitate partners’ joint and informed decision making, joint responsibility for conception or contraception, and eventually contribute to reducing the incidence of induced abortion.

Disputable Issues in the Russian History of the 16th Century
Authors: Rasmussen Knud
Published: April 2019

Knud Rasmussen (1930–1985) was a famous Danish historian, Professor at Institute of Slavic Studies at University of Copenhagen, specialist in medieval Russia, author of a dozen of scientific monographs published in large editions including in Russian. In 1973, he defended his thesis titled “The Livonian crisis of 1554–1561”. According to the list of works published by J. Lind, 13 publications are devoted to the epoch of Ivan the Terrible. This article, published for the first time, is presented in the form of a report at the conference in Hungary. The scientist consistently outlined the main tasks and problems related to the study of Russian history abroad, in particular, in Denmark. He told what plan was built for the team of Danish historians who decided in the early 1970s to prepare a textbook on Russian history in the form of a problem historiographic course for Danish students, and how this plan was implemented. The study of works on Russian history and their systematization helped the team of Danish historians, which included K. Rasmussen, develop a special historiographic method and its principles, which led to developing understanding of the problematic historical field as a whole and placing individual research in it. As a result, a multivolume manual was written; by the time of K. Rasmussen’s speech, 3 volumes were published, covering the period of Russian history from the 17th to the 20th century inclusive. K. Rasmussen worked on preparing a volume on the Russian history of the 16th century. In the second part of his speech (article), the author shared his thoughts on the chosen approach to the assessment of historiography and spoke about the content of this volume, where he outlined the controversial problem of enslaving peasants, discussions on the reasons for backwardness of Russian cities as the basis of Moscow defeats in Livonia, possible ways of Russian revival, on the state and its institutions and on the development of historical events in the field of domestic policy. This volume was published after the death of the author in the same year: Rasmussen Knud. Ruslands historie i det 16. Arhundrede: En forsknings-og kildeoversigt. Kobenhavn, 1985. 161 s.

This research paper is devoted to the topic of gabion structures in the road construction. Nowadays, gabion structures are one of the key tools to protect beach line, caving, strengthening slopes of embankments and depressions, slopes, ravines and other road and bridge structures. The world experience shows that gabion structures are one of the most universal, effective and perspective structures used in construction of road and bridges. In this article gabions are considered as strengthening of culvert heads. In the work are presented the theoretical aspects of these constructions and analysis of gabions and traditional structures in order to estimate the effectiveness of these constructions in strengthening of culvert heads. For each type of construction has been formed cost account thanks to in research was analyzed economical aspects. In addition, based on the received data in this article presents an empirical analysis of the relevance of considered hypotheses. Thus, based on an estimation of structures in the research was revealed that the most effective for strengthening the heads of culverts is a structure in combination with gabions and riprap. The conducted research and experience of road and bridge construction of many countries, including the domestic experience of recent years, demonstrated that gabion constructions have very wide capabilities and properties, such as economy, strength and durability, which are importance key for the road construction.
Analysis of the influence of environmental factors on the economic development of the region (on the example of the Republic of Mordovia)
Authors: Zemskova Zemskova
Published: April 2019

For a long time, the gross domestic product was the only indicator that allowed one or another state to be classified as “developed» or «developing» without taking into account the created externalities. It is now recognized that not only the amount of added value, but also the environmental factor, appears as an important element of a regional socio-economic system that makes it possible to understand how resource-saving the economy is and to form the basis for sustainable development of the territory. The importance of reflecting the environmental factor in generalizing indicators of the economic development of the territory does not raise doubts at the highest state level, as evidenced by a number of policy documents adopted by the Government of the Russian Federation. In this article, the author has attempted an alternative assessment of sustainable development in the region, taking into account the environmental factor. The subject of the study is the problems of measuring the balance of the ecological and economic development of the territory. As methods in this article, we used analysis, synthesis, deduction, and forecasting in the exponential smoothing model in the Statistica program. On the basis of a compilation of available official statistics, it was decided to use the forecast of the adjusted GRP of the Republic of Mordovia, taking into account the output of the extractive sector and investment in the region in the region. The results of the calculations carried out by the author have demonstrated that GRP, taking into account the criteria of sustainable development, will be greater than the actually predicted value of gross output in the region. In addition, the integration of the integrated environmental index in the calculation of the adjusted GRP will make it possible to reflect more in the indicator the contribution of current environmental pollution. The proposed recommendations can be used to improve the constructed forecast models and conduct inter-regional comparisons.
The actual operation assessment of the railway bridge superstructure using a mobile monitoring system
Authors: Baranov Timofey , Tolstikov Evgeniy
Published: April 2019

Deviations in the operation of the operated bridge structures on the railway are detected when damage occurs. At the same time, early detection and prognosis of damage progress can be obtained using monitoring systems. The article presents the methods and technologies for the use of mobile monitoring systems for assessing the actual operation of the metal superstructure of the railway bridge with the main driving trusses. The hardware of the measuring complex is considered, the main measuring instrument is the glued electrical strain gauges. The monitoring system kept a continuous record of sensor readings for 28 days. To process the data received by the monitoring system, specialized software has been developed that systematizes the incoming information. Analysis of the actual supertructure operation is carried out by finding the relationship of stresses in the various elements of the superstructure, arising under the same load. This approach allowed us to exclude the factor of unknown intensity of the temporary load. The results of monitoring the work of the superstructure are given. In total, over 680 train passage records were analyzed, which allowed for a statistical description of the data. The theoretical values of the relationship of stresses in the elements of the superstructure are determined using the apparatus of the influence lines obtained by a numerical method. The conclusions are made about the distribution of deformations of the superstructure under temporary load and about the degree of compliance with theoretical calculations. The construction factors and the values of their statistical scatter are determined, the actual dynamic factors are statistically calculated. The construction factors calculated from the stress ratios lie in the range of 0.8-1.116. Dynamic factors are within 1.13 and do not exceed the rated values.

Background: Chronic pelvic pain of myofascial origin is an underdiagnosed condition and with partial responses to the different treatment modalities. The objective of this study was to report the results of the multimodal management of Myofascial Chronic Pelvic Pain.Methods: Retrospective cohort of 33 patients with myofascial chronic pelvic pain, during the period 01 January 2016 to August 31, 2018, who were treated based on trigger point infiltration and analgesic vaginal electrostimulation. The analogous visual pain scale (VAS) was used at the beginning, sixth, twelfth and six months after the last electrostimulation session, in order to measure the effect of the treatment.Results: During the study period, 32 patients with chronic myofascial pelvic pain were found who received the multimodal scheme that is offered in our clinic. The average score of the EVA before starting the treatment was 8.5 points, at the sixth session of the treatment the average EVA was 3.6 points, at the twelfth session of 1.3 points and the average score of the EVA at six months after the last session of the multimodal treatment was 2.9 points. A significant difference was demonstrated in the average EVA score in the first with respect to the sixth, twelfth and six months (p = <0.000). There were no complications or adverse effects secondary to the multimodal treatment.Conclusions: Multimodal treatment was associated with progressive improvement in 80% of patients with miofascial chronic pelvic pain.

Published: April 2019

Background: Arterial tone parameters in young African women during the different phases of menstrual cycle were assessed in the present study.Methods: Out of the 30 student volunteers who participated in the study, only 15 completed the study. Anthropometric data using stadiometer, blood pressure using automated oscillometric pressure gauge were measured. Arterial stiffness parameters at the radial and ECG gated carotid and femoral arteries using sphygmocor tonometry was mesured in two consecutive menstrual cycles at early follicular, ovulation and luteal phase. Estrogen and progesterone concentrations were analyzed using Elisa kits in all three phases.Results: Estrogen level in ovulation phase and progesterone in luteal phase were higher. Peripheral augmentation index in ovulation phase was higher compared to luteal phase. Pulse pressure amplification value at follicular and luteal phases was higher than in ovulation phase. Pulse wave velocity and pulse pressure amplification was negatively correlated to progesterone in follicular phase. The arterial stiffness increased at ovulation and decreased in follicular and luteal phases of menstrual cycle.Conclusions: No significant correlation between arterial stiffness parameters and ovarian hormones was found.

Background: The term dysfunctional uterine bleeding (DUB) is used for abnormal uterine bleeding occurring in the absence of identifiable pathology. A number of drugs are available for management of DUB- nonsteroidal anti-inflammatory drugs, tranexamic acid, ethamsylate, hormones like Oral contraceptives progestins etc. The present study was done to determine the efficacy and safety of ormeloxifene in the management of DUB.Methods: This prospective clinical study involved 50 cases with DUB who were treated with ormeloxifene 60 mg tablet twice a week for first 12 weeks and the once a week for next 12 weeks. They were followed after 6 months of therapy. The outcome was studied by assessment of menstrual blood loss by PBAC score, Hb level in g/dl, endometrial thickness in mm, relief of dysmenorrheal and any side effects of drugs.Results: The median PBAC score was significantly reduced from 316 to 52 after 6 months of therapy. The mean Hb concentration was significantly increased from 7.8 g/dl to 9.1 g/dl at 6 months of therapy. The mean endometrial thickness was reduced from 10 mm to 7.9 mm after 6 months of therapy. 66% of women showed marked subjective improvement in symptoms. Amenorrhea was the main side effect (12%).Conclusions: Ormeloxifene has significant effect in reducing endometrial thickness, decreasing the amount of menstrual blood loss, reducing dysmenorrhea and thereby improving the general condition of the patient. It is definitely a better alternative to hysterectomy in women who wish to avoid surgeries and maintain their reproductive functions.

Background: The risks to the fetus increase after 41 weeks mainly due to increasing fetal weight, decline in placental function, oligohydramnios which increase chances of cord compression, and meconium aspiration. Perinatal mortality after 42 weeks is twice as compared to the perinatal mortality at 40 weeks and by 44 weeks the rate is increased up to threefold. In cases of prolonged pregnancy, fetus is more at risk of hypoxia during labor than a fetus at term.Methods: This cross sectional observational study of feto-maternal outcome in post dated pregnancy (Women beyond 40 weeks of gestation) was carried out in the department of obstetrics and gynaecology in a rural based tertiary care centre from October 2016 to September 2018, willing to participate and fulfilling the inclusion and exclusion criteria in the study period.Results: Majority i.e. 45 patients (46.9%) went into spontaneous labour and delivered vaginally, whereas 16 patients (16.7%) required caesarean section. Among all 45 participants who were given induction, maximum 26 (57.78%) were induced by Dinoprostone gel, 4 patients (8.89%) were induced by Tab. Misoprostol.Conclusions: The present study, we conclude that, the post dated pregnancy can be considered as a high risk factor from the point of view of fetal outcome as there is more fetal morbidity.

Background: Changes in thyroid function in normal pregnancy are well-documented but in complicated pregnancy like preeclampsia, very little is known. Studies have shown evidences of hypothyroidism in preeclampsia necessitating thyroid function tests to be done in preeclampsia. The study was done to analyze the fetomaternal outcome of preeclampsia with coexisting thyroid dysfunction.Methods: A cross-sectional analytical study was done over 18 months on 95 preeclamptic patients admitted at the antenatal ward and fetomaternal outcomes were analyzed according to thyroid status.Results: Out of 95 patients with preeclampsia, 42 (44.2%) had thyroid dysfunction. Among these 42 patients, 37 (38.9%) patients had subclinical hypothyroidism, 4 (4.2%) had overt hypothyroidism and 1 (1%) had hyperthyroidism. Severe preeclampsia was seen in 64.3% of the patients with thyroid dysfunction compared with 39.6% in euthyroid patients. The mean thyroid stimulating hormone (TSH) level was significantly higher and means free thyroxine (fT4) level was significantly lower in severe preeclampsia compared with non-severe preeclampsia. Complications like abruption, intrauterine fetal death (IUD), intrauterine growth restriction (IUGR), oligohydramnios, preterm deliveries, postpartum hemorrhage (PPH), low birth weight babies, birth asphyxia in babies and subsequent neonatal intensive care unit (NICU) admissions were significantly higher (p <0.05) in the preeclampsia patients with thyroid dysfunction in comparison with euthyroid ones.Conclusions: Hypothyroidism may be a modifiable risk factor for preeclampsia. Thyroid screening early in pregnancy may be helpful in predicting the occurrence of preeclampsia and timely thyroid hormone administration can reduce the maternal and perinatal morbidity and mortality associated with preeclampsia.

Background: Oligohydramnios is the term coined for a condition where the amount of liquor amnii is less than 200 ml at term. Using an ultrasonogram, oligohydramnios can be deliberated when the vertical pocket of liquor is less than 2 cm or when amniotic fluid index (AFI) is less than 5 cm. Oligohydramnios is reported to occur in 1 to 5% of total pregnancies. It has been associated with adverse maternal and foetal outcomes.Methods: This hospital-based follow-up study was conducted among 540 pregnant women at 37 weeks attending to the Department of Obstetrics and Gynaecology for a period of 1 year from January to December 2018. All included pregnant women were subjected to routine ultrasound examination and assessment of amniotic fluid volume using Amniotic fluid index.Results: The incidence of oligohydramnios was 17.04% (n=92) among the included women and 62% (n=57) among them were primigravida. Among those women diagnosed with Oligohydramnios, the caesarean section rate was 56.5% (n=52), the common indications for LSCS being fetal distress 44. 2% (n=23) and IUGR 34.6% (n=18). The oligohydramnios pregnancies had more associated post-dated deliveries (28.3%), pregnancy induced hypertension (10.9%) and gestational diabetes (8.7%). It was also associated with higher incidence of low birth weight (27.2%), NICU admissions (32.6%), congenital anomalies (3.3%) and fetal deaths (5.4%).Conclusions: The study showed that an amniotic fluid index of less than 5 at term was associated with adverse maternal and perinatal pregnancy outcomes emphasizing the importance of amniotic fluid volume surveillance during the antenatal period.

Background: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in reproductive age women. Some of the PCOS women show presence of hypothyroidism.Methods: This study was conducted at tertiary care centre Indira Gandhi Government Medical College and Hospital (IGGMC), Nagpur, Maharashtra, India. The study group had 50 diagnosed patients of PCOS and 50 age matched normal regular menstruating women were taken as controls.Results: In this study, PCOS patients showed higher mean TSH level than control group (4.024±1.09 and 2.84±0.83 respectively). And more women were diagnosed with overt hypothyroidism in the PCOS group (6%) than in the control group (2%).Conclusions: The findings of the study showed that PCOS is associated with hypothyroidism as compared to normal population.

Background: Pregnancy, although being considered a physiological state, carries the risk of serious maternal morbidity and at times mortality, due to various complications that may arise during pregnancy, labour or thereafter. The existing medical condition, infection, and surgical condition which is collectively called as non- obstetric cause pre disposes a women for more complication than a non-pregnant women, so much so that it can lead to maternal mortality. Thus, Pregnancy is more vulnerable state and present study was carried out to study, analyse and review various non-obstetrics causes of death of women during pregnancy or within 42 days of termination of pregnancy in Tertiary care centre.Methods: This was an Observational study, conducted in the department of obstetrics and gynaecology, at a tertiary care hospital attached with medical college, from October 2016 to October 2018. The details of maternal deaths were collected from various departments with non- obstetric causes and analyzed.Results: The total number of deliveries in my study period was 15,208. There were 197 maternal mortality in our study period, of which 51 women died of non-obstetric causes. The most common cause of maternal mortality in our study was hepatic cause i.e. 33.33% amongst which viral hepatitis was the most common cause followed by respiratory (19.60%), infectious (15.18%), heamoglobinopathy (13.72%), cardiac (5.88%), neurological (5.88%), surgical (5.88%) causes.Conclusions: Looking into our study, maternal mortality can be reduced by identifying various different indirect medical causes which are preventable by proper pre-pregnancy evaluation for pre-existing comorbid conditions.
