Alterations of bacterial dielectric characteristics due to pulsed magnetic field exposure
Authors: El-Kaliuoby Mai Ismail , Khalil Alaa Mahmoud , El-Khatib Ahmed Mohamed
Published: January 2020

The effect of exposure to 0·1 Hz–0·1 kHz pulsed magnetic fields on models of gram-positive and gram-negative bacterial cells was investigated. The possible alterations in the electrical characteristics of dead and alive bacteria cells were monitored by using dielectric spectroscopy. The dielectric dispersions of cells were obtained over the range 42 Hz–8 MHz by measuring their dielectric permittivity and conductivity. The acquired results indicated exposure enhancement and inhibition effects on both bacterial models in different frequency windows. The spectroscopy results for all bacterial cells indicated two sizeable dispersions in low- and high-frequency ranges (so-called α- and β-dispersions) due to different polarization mechanisms. Remarkable variations in the dielectric relaxations were observed due to exposure as a result of possible alterations in the counterion clouds and ionic membrane permeability, plasma and cell wall charge residues. In conclusion, both bacterial models demonstrated considerable response to exposure, resulting in a significant electrochange in the cell membrane/wall structure. Moreover, by performing dielectric spectroscopy, it is possible to distinguish between normal and abnormal cells. It is worth mentioning that the observed results can be achieved when using resonance frequencies outside the range used in the study.
Collaborative maritime design using sequential optimisation and reliability assessment
Authors: Meng Debiao , Li Yan , Zhu Shun-Peng , Hu Zhengguo , Xie Tianwen , Fan Zhengrong
Published: January 2020

The collaborative design of maritime structures involves not only multiple disciplines, but also uncertainty of information. Collaborative optimisation (CO) is a powerful multidisciplinary design and optimisation strategy known for its two-layer structure. In the original mathematical formulation of system-level optimisation, the second-level compatibility constraints are utilised. However, this makes a system-level CO algorithm have additional non-linear characteristics. Furthermore, during design optimisation considering uncertainty, the introduction of uncertainty quantisation increases complexity. Overall, the approach can reduce accuracy and efficiency. To solve these problems, a decoupling strategy called sequential optimisation and reliability assessment is proposed in this paper together with a collaborative uncertainty design and optimisation model. Three examples are provided to show how this hierarchical strategy can be applied to modern distributed maritime engineering design processes.

Published: January 2020

Modified LSK109 ligation prep using needle shear and bead purification Using HMW DNA purified as above we have been performing 29G and 26G needle shears to produce fragmentation to around 18Kb and 34kb respectively (reported read N50’s after basecalling). Also by going into the library preparations with 5-10ug of DNA have been able to produce enough material to provide up to 10 library loads from a single prep. We have not been performing the FFPE repair during the end-prep step, and have been diluting the sample at the cleanup points in the protocol with EB to prevent bead clumping during 0.4-0.5x AMPureXP purifications when DNA fragments are large and at high concentrations. Shown below are the results from a batch of 12 runs we performed using this approach.

Authors: Takahashi Hazuki , Nishiyori-Sueki Hiromi , Carninci Piero
Published: January 2020

The Cap Analysis of Gene Expression (CAGE) is a powerful method to identify the Transcription Starting Sites (TSSs) of capped RNAs while simultaneously measuring transcript level. CAGE allows mapping at single nucleotide resolution all active promoters and enhancers. Large CAGE datasets have been over the years by individual labs and consortia, including the Encyclopedia of DNA Elements (ENCODE) and Functional Annotation Of the Mammalian Genome (FANTOM). These dataset constitute open resource for TSS annotations and gene expression analysis. Here we provide a protocol for the most recent CAGE version of the method, which is called Low Quantity (LQ) single strand (ss) CAGE (LQ-)ssCAGE. The methods allow to profile samples starting from low quantity of RNAs. Samples may typically include cells cultured in small volumes to maximizing large scale perturbations, cellular compartments like nuclear RNAs or samples from developmental stages. The advantage of (LQ-)ssCAGE is to allow working with small samples and simultaneously avoiding PCR amplification: this step help to preserve exquisite quantification of expression. The protocol makes use of simplified steps, by loading single stranded cap selected cDNA. Further, is allows reducing the RNA amount down to 25 ng and to shorten preparation time (less than 3 days) and to prepare libraries parallel, increasing the number of samples that one operator can reasonably handle (up to 96 samples). By proper organization of the flow of libraries preparation, an operator could further scale up the throughput. The obtained libraries are suitable for sequencing by various Illumina sequencing platforms using indexed reads and original barcode identifiers.

Published: January 2020

Personal safety is a critical aspect of daily life, but also in the military. Active soldiers often have to carry heavy gear during missions, which puts pressure on their backs. Therefore, the military must come up with new technologies that allow both protection and movement. In this paper, it is explaining the development of an armored upper limb exoskeleton with three degrees of freedom. To ensure portability, it is used battery-fed DC actuators. The system was encased in a metal matrix that doubles up as a protective plate. The exoskeleton, the control system, the actuators, and the plate are integrated so that they offer protection while supporting the flexion and extension of the upper limb.

Authors: Berrios-Barcena David Reinaldo , Franco-Rodríguez Rosendo , Rumiche-Zapata Francisco Aurelio
Published: January 2020

A procedure to calibrate the NASGRO equation in a high yield-strength steel under mixed-mode loading (I + II) is presented. The calibration consists in obtaining the material parameters known as C, m, p and q. The procedure is based on experimental and numerical results. The experimental tests were used to characterize the material and obtain fatigue crack growth data. For the fatigue tests, tapered double cantilever beam (TDCB) specimens with different maximum load and load ratio values were used. Through the numerical analysis, the stress intensity factors, the crack growth direction and the crack path coordinates were calculated. The numerical analysis was performed using XFEM and the maximum energy release rate criterion. The calibrated model allows predicting the number of load cycles with an RMS value of less than 5%, compared with the experimental results.
DANIEL BELL ABOUT THE «FLUIDITY» OF AUTHORITIES IN THE AGE OF POSTINDUSTRIALISM
Authors: Sashchuk Hanna
Published: January 2020

The article analyze the position of one of the most respected researchers of post-industrialism, Daniel Bell, on the impact of new information technologies on “politics-power” relations. The following two features of the influence of information and knowledge on the political sphere of public life are clarified: “Situs as Political Units» and «Rightful Meritocracy.” According to D. Bell, there are three analyzed current models of power: 1) the previous model of power, which is based on property, and besides it is inherited; 2) a model of government, the basis of which is knowledge acquired through education; and 3) a model of power, the source of which is a political office obtained through an organizational apparatus. The concept of the rightful meritocracy of D. Bell was analyzed, it’s meaning in the idea that the power belong to the most gifted. He believed that a capitalist society іs gradually transforming into a society in which gifted people will be promoted to senior positions, including political. He defined a certain “merit formula”: “Intelligence + Achievements = Merit”. D. Bell argued, that people with such merits should take up leadership positions in politics, business, science and other activities. In post-industrial society, the principle of “achievement” is relevant, there is a thought, that power is achieved through the personal virtues of the people, their high level of education and skills. In such society, there are almost no senior positions available to people without qualifications. In conclusion, we can say that the politician, from the point of view of D. Bell, is a highly skilled specialist which have the necessary management skills. Post-industrial society implies the emergence of a new intellectual class, whose representatives can at political level act as consultants, experts or technocrats.

Authors: Lamenha Lins R M , Cavalcanti Campêlo M C , Mello Figueiredo L , Vilela Heimer M , dos Santos-Junior V E
Published: January 2020

Objective: To establish the prevalence of Probable Sleep Bruxism (PSB) and its association with gender, breast or bottle-feeding, posterior and anterior crossbite, oral habits and oral breathing. Study Design: Consists of a cross-sectional study in which 151 children were submitted to a clinical oral examination for the evaluation of tooth wear, muscle discomfort and the presence of anterior and/or posterior crossbite. Parents/caregivers were asked about the frequency of teeth grinding during the child's sleep and the occurrence of harmful oral habits, as well as the type of childbirth and breastfeeding. Data were statistically analyzed through Chi-square or Fisher's exact tests at a 5% level of significance to determine an association among variables. Results: The prevalence of PSB was of 27.8% among the examined children. Among the analyzed variables, only oral breathing was statistically associated to PSB (p < 0.001), and it was verified that children with oral breathing are 2.71 times more likely to present sleep bruxism. Conclusions: The prevalence of PSB in schoolchildren was high and the disorder was associated with oral breathing. Thus, pediatric dentists have an important role in the diagnosis of sleep bruxism and in monitoring breathing-related disorders.

Published: January 2020

Regenerative endodontic therapy (RET) provides a novel treatment modality for the immature teeth with pulp necrosis. The aim of this case series was to evaluate RET of immature permanent teeth using platelet rich fibrin (PRF) at 36-month follow-up periods. In the present case series, three immature maxillary incisors diagnosed with pulp necrosis and apical periodontitis were treated with RET. The root canals were irrigated with 1.5% sodium hypochlorite (NaOCl) and medicated with triple antibiotic paste(TAP). At the second visit, TAP was removed and root canals were conditioned with 17% EDTA. PRF was used as a scaffold. MTA was placed over PRF and the teeth were restored with composite resin. Periapical radiographs and cone beam computerized tomography(CBCT) were used to evaluate the healing. At the end of the 36-month follow-up periods, there was no response to pulp sensibility tests with cold and electric pulp tester, but all teeth showed decreased periapical lesions or evidence of healing.

Published: January 2020

Purpose: Molar Incisor Hypomineralization (MIH) is a developmental enamel anomaly of systemic origin affecting the first permanent molars and often the permanent incisors. Despite MIH being a prevalent anomaly, its diagnosis and management are challenging for practitioners; including poor anesthesia, failure of restorations, rapid enamel breakdown, poor resin adhesion, and related child anxiety. This study aimed to evaluate knowledge regarding and management of MIH amongst orthodontists and dentists. Study design: The study was performed from March to September 2017 and included 336 dentists and 32 orthodontists. Questionnaires comprised questions on MIH diagnosis, socio-demographic characteristics of the subjects, and photographs of a case of MIH with related questions regarding management. Results: Our results showed that 48% of dentists and 25% of orthodontists misdiagnosed MIH; with misdiagnosis associated with graduation prior to 1986 (p < 0.001). Amongst dentists, 59% applied a fluoridated product and 34% applied fissure sealants in the case of moderate MIH. The application of fluoride was associated with graduation after 1986 (p < 0.0001).Conclusion: Large disparities about knowledge and management of MIH exist between dental practitioners in France. Education regarding diagnosis and management of MIH is necessary.

Published: January 2020

Myopia in schoolchildren is a serious problem. The frequency of its detection in the lower grades of the school is 68%, and by the end of school at least 2530%. In special school this indicator reaches 50%, which is associated with more intense and longer visual loads, prolonged work at the computer and more frequent use of other electronic storage media. The genesis and progression of myopia is largely due to the intensive educational process in which schoolchildren are involved already from the first year of study, as well as to the corresponding violations of the hygiene of their visual work at close range. The article presents the results of a retrospective analysis of case histories of 53 school-age children living in St. Petersburg. The role of socio-hygienic factors related to the schoolchildrens connected their family life (including material well-being) and the availability of modern technical means (computers, video game consoles, mobile phones, etc.) was studied. An analysis of external factors (deficient physical activity of the child, change of the daily regimen, later visit of the childs parents by an ophthalmologist), which have a negative impact on the development and progression of myopia in schoolchildren, was also relevant. Based on the results of the study, recommendations were developed for the observation and correction of myopia in schoolchildren.
Glycated proteins
Authors: Danilova Lubov A.
Published: January 2020

Glycation is a biological reaction that occurs in all proteins. Thisreaction proceeds more slowly in healthy subjects and more rapidly in patients suffering from a hyperglycemia. Glycated proteins cannot fulfill their functions that could lead to metabolic disorders. The process of glycation leads to building of advanced glycation end-products (AGEs). Thestructureof AGEs has not been fully researched yet. Glycated proteins have diagnostic meaning in different health conditions and not only in patients with diabetes mellitus. Determination of glycated proteins level (hemoglobin and plasma proteins) in diagnostics of diabetes mellitus and the effectiveness of its treatment; measurements of glycated proteins could be used as a predictor of different illnesses and their complications. Glycated hemoglobin was researched in children with diabetes mellitus of different severity. It has been shown that the level of glycated proteins does not always correlate with blood sugar level. Results of glycated proteins measurements in patients with thyroid disorders shows that the glycation takes place not only in patients with diabetes mellitus, but also with other illnesses without hyperglycemia. Our research in patients with diabetes mellitus has shown that the measured level of glycated proteins and plasma proteins could be more significant in the course of disease than the level of blood sugar. Compensation of diabetes mellitus in children in regard of the blood sugar level does not always correlate with the level of glycated proteins. This assumption could lead to the conclusion that only the combination of measurements like blood sugar, glycated hemoglobin and glycated proteins could give a full picture of disease compensation.

Published: January 2020

Pituitary gigantism is a disease caused by an excess of growth hormone and characterized by tallness with a proportional increase in all parts of the body. Almost always in patients with pituitary gigantism found pituitary adenoma, producing growth hormone (somatotropin). In rare cases, there is excess production of somatoliberin by the hypothalamus or tumors outside the brain. Somatotropinoma can be sporadic or caused by a disease with genetic defects: multiple endocrine neoplasia type 1, McCuneAlbright syndrome, Carney complex, X-LAG syndrome, AIP-mutation. All associated with genetic defects somatotropinoma more invasive and less amenable to drug therapy than sporadic. Clinical recommendations (protocols) for the treatment of pituitary gigantism in children currently does not exist. The issue of preliminary medical treatment to improve the outcome of neurosurgical interventions has not been resolved, and further methodologically based studies are needed to clarify this point. The article presents a clinical case of pituitarygigantism caused by pituitary adenoma, which produces growth hormone in a 12-year-old boy. The diagnosis was established on the basis of clinical and anamnestic, laboratory data and magnetic resonance imaging. Clinical and laboratory manifestations of hypopituitarism and diabetes insipidus, visual field disorders, neurological symptoms, as well as signs of genetic diseases in the patient were not noted. Treatment with bromocriptin gave a partial positive effect: the size of the formation in the pituitary gland decreased, but the target hormonal parameters were not achieved. A trial administration of octreotide subcutaneously was carried out, as a result of which the level of growth hormone decreased to the target values, no side effects of the drug were noted, which led to the choice of a conservative method as the first line of therapy. Thedecision to treat with bromocryptine in combination with octreotide extended action. The dynamics of tumor sizeonthebackgroundofconservative therapy will answer the question of the need for subsequent neurosurgical treatment.
A Myth of Preferred Days of Strong Earthquakes?
Authors: Kossobokov Vladimir G. , Panza Giuliano F.
Published: January 2020

Existing evidence on the origin times of magnitude M≥7.5 earthquakes worldwide, based on authoritative earthquake catalogs, does not permit rejection of the null hypotheses of random coincidental occurrence at any time during the Earth or the Moon cycles. Specifically, the nonparametric Kuiper test statistics for cyclic variations applied to seismic evidence resulting from the empirical distributions of the M≥7.5 earthquake origin time Julian day (JD) and the Moon phase (MP) do not allow the rejection of the null hypotheses of uniform distributions within the corresponding cycles. On the other hand, the same Kuiper test permits the rejection of the null hypotheses of the same chance of occurrence on any JD or MP for strong magnitude M≥6.0 earthquakes, at least for the past four decades of presumably the best-earthquake determinations and, in particular, for earthquakes in the Northern Hemisphere (with an evident seasonal pattern). The nonparametric two-sample Kolmogorov–Smirnov test statistics suggest no preferred distances to the Moon at the occurrence of large earthquakes. All of this contributes, to the results of solid statistical testing of hypotheses, for a better understanding of the complex seismic response of the Earth’s lithosphere to periodic gravitational loading.

Numerical simulations of sequences of earthquakes and aseismic slip (SEAS) have made great progress over past decades to address important questions in earthquake physics. However, significant challenges in SEAS modeling remain in resolving multiscale interactions between earthquake nucleation, dynamic rupture, and aseismic slip, and understanding physical factors controlling observables such as seismicity and ground deformation. The increasing complexity of SEAS modeling calls for extensive efforts to verify codes and advance these simulations with rigor, reproducibility, and broadened impact. In 2018, we initiated a community code-verification exercise for SEAS simulations, supported by the Southern California Earthquake Center. Here, we report the findings from our first two benchmark problems (BP1 and BP2), designed to verify different computational methods in solving a mathematically well-defined, basic faulting problem. We consider a 2D antiplane problem, with a 1D planar vertical strike-slip fault obeying rate-and-state friction, embedded in a 2D homogeneous, linear elastic half-space. Sequences of quasi-dynamic earthquakes with periodic occurrences (BP1) or bimodal sizes (BP2) and their interactions with aseismic slip are simulated. The comparison of results from 11 groups using different numerical methods show excellent agreements in long-term and coseismic fault behavior. In BP1, we found that truncated domain boundaries influence interseismic stressing, earthquake recurrence, and coseismic rupture, and that model agreement is only achieved with sufficiently large domain sizes. In BP2, we found that complexity of fault behavior depends on how well physical length scales related to spontaneous nucleation and rupture propagation are resolved. Poor numerical resolution can result in artificial complexity, impacting simulation results that are of potential interest for characterizing seismic hazard such as earthquake size distributions, moment release, and recurrence times. These results inform the development of more advanced SEAS models, contributing to our further understanding of earthquake system dynamics.
MEDIUM OPTIMIZATION FOR PROTEASE PRODUCTION VIA MODERATELY HALOTOLERANT VIRGIBACILLUS PANTOTHENTICUS USING RESPONSE SURFACE METHODOLOGY
Authors: BANGER Gizem , NİKEREL Emrah
Published: January 2020

Virgibacillus pantothenticus is an industrially promising, yet scarcely studied, moderately halotolerant microorganism (up to 10% NaCl) with high activity protease production potential. Following Response Surface Methodology, we employed a Central Composite Design for the experiments and constructed a second order polynomial model to represent the resulting data. For medium optimization for protease production we optimized the resulting model. 32 experiments (following the central composite design scheme) where, carbon (glucose), nitrogen (ammonium sulfate), potassium (potassium phosphate monobasic) and magnesium (magnesium sulfate) sources were studied in the media. Bacterial growth, residual glucose and protease activities were determined at the 48th hour of each experiment. The model was optimized and the concentrations were found for each parameter. Under the optimum conditions, the predicted protease activity is also experimentally verified and the model prediction was in very good agreement with experimental results. The interactions between medium components and their effect on cell growth and protease production are also sought. This work reports the improvements on protease production of a potentially interesting industrial host, Virgibacillus pantothenticus.

The research was carried out using the explanatory sequential mixed method design of the mixed method designs. In the quantitative part of the study, the sample group consisted of 380 children, their families and teachers, and the qualitative part participants consisted of 9 children, 9 families and 9 teachers. As a result of the study, it was concluded that there was a statistically significant difference between the employment status of the mothers and the overprotective parent attitudes. Teachers stated that there were children in their classroom who did not like school and showed the behavior of not wanting to come to school and that these were caused by reasons such as family problems, over-dependence on the mother and absenteeism. The conclusion has been reached that some teachers were not aware of children who have problems with school adjustment. It was found that a part of the parents stated that their children did not want to go to school because of reasons such as getting caught up in play at home, sleeping problems (being unable to wake up in the morning) and making excuses not to go.

Background: Urinary tract infection is a common pathology during pregnancy due to hormonal and morphological changes. Objective of this study was to improve management of urinary tract infection during prenatal care.Methods: A total of 987 pregnant women who have been in prenatal care have freely accepted to participate in cross-sectional study carried out from 1st May 2016 to 30th April 2017 at Yopougon University Hospital (Abidjan Côte d’Ivoire) were included. Patients were submitted to questionnaire by one of investigators for epidemiological component and then physical examination was carried out by her attending physician for clinical component. Then at laboratory urine was taken for culture after dipstick test.Results: Of the 987 patients included 9.4% had a urinary tract infection of which 81.7% were asymptomatic. Significant risk factors retained were existence of a history of urinary tract infection (OR=0.46; p=0,038) and gestational age of pregnancy (OR=0.44; p=0.05). Urine culture isolated germs were mainly Escherichia Coli (51.6%) and Klebsiella pneumoniaie (23.6%). These germs were all susceptible to cephalosporins. They had resistances of more than 50% to penicillins.Conclusions: Escherichia coli and Klebsiella pneumoniae are most common germs of urinary tract infections in pregnant women. Escherichia coli is not susceptible to penicillins with a resistance of 70% for penicillins except for clavulanic acid amoxicillin. It appears as first choice antibiotic for our prescriptions in case of probabilistic antibiotic therapy.
A prospective study of outcome in infertility patients diagnosed with genital tuberculosis
Authors: Yadav Sumitra , Kumar Neha
Published: January 2020

Background: Tuberculosis is an increasing health problem worldwide with around 9.6 billion new cases reported every year. Female genital tuberculosis (FGTB) has a varying incidence ranging from a very low of 0.69% in developed nations to as high as 19% in developing nations like India. The average incidence of infertility due to tuberculosis is 5-10% worldwide.Methods: The study was a hospital based prospective clinical study, from September 2014-2017 with sample size of 355 infertility cases. Endometrial sampling and diagnostic hystero-laparoscopy were used for diagnosis. Endometrial sample subjected for both the test CBNAAT and HPR was used for confirmation of positive patients. Inclusion criteria were, infertile patients diagnosed with genital tuberculosis who were then given treatment. Patients diagnosed to have infertility due to causes other than TB were excluded from the study. Highly suspected cases and those who were willing underwent diagnostic laparoscopy.Results: Out of 355 cases of infertility, 83 were because of genital TB, received treatment out of which 32 conceived.  CBNAAT was very sensitive than histopathology or laparoscopy. The live birth rate and conception rate were 20.24% and 38.09 % respectively.Conclusions: CBNAAT is OPD based economical test (free by GOI), very sensitive and picked up more cases than histopathology or laparoscopy. The live birth rate and conception rate were found to be higher than other studies possible due to intervention at an earlier stage of the disease process. This test should be widely used by gynecologist for early detection of genital tuberculosis.

Authors: Patil Soumya R. , Patil Rajesh
Published: January 2020

Background: Worldwide Infertility rate prevails around 8-12% of all couples; approximately 80 million are infertile. In India 10-15% of couples are infertile. Investigating for infertility is to intervene into the modifiable/treatable causes. Therefore, the present study has been undertaken to investigate the morphological patterns of endometrial tissue in women with primary infertility.Methods: The study included 60 cases with complaints of infertility (primary). The premenstrual D and C was done to obtain endometrial biopsy. The present prospective study was a descriptive study and the values are mentioned in percentages.Results: In present study a total of 60 cases were studied. Out of which 36 cases (60%) belonged to the young adult age group. The predominant morphological pattern was that of secretory endometrium seen in 22 cases (36.66%) as opposed to proliferative, endometritic or tubercular pattern. The predominant menstrual pattern recorded was regular; seen in 41 cases (68.33%) as opposed to irregular or mennorhagic patterns.Conclusions: The endometrial biopsy has a great role in screening the cases of infertility as it helps to assess the information about ovulation, ripening of the endometrial tissue and other abnormal endometrial reaction, hormonal imbalance. This is the only method to label the diagnosis of endometrial tuberculosis in an apparently healthy female.

Authors: Saxena Rajiv Kumar , Ansari Noor Fathima Tameem , Singh Pallavi
Published: January 2020

Background: The oral glucose tolerance test (OGTT) is considered the current standard for diagnosis of gestational diabetes mellitus (GDM). International association of diabetes and pregnancy study groups (IADPSG) recommends OGTT, with fasting, one-hour and two-hour venous blood samples drawn after intake of 75g oral glucose. In the Indian context, diabetes in pregnancy study group in India (DIPSI) recommends glucose challenge test (GCT), where 75 g glucose is given irrespective of the fasting state, and a single venous sample is drawn after two-hour. Diagnosis of GDM is made, if any cut-off value is met or exceeded. This prospective study was conducted to compare the DIPSI and IADPSG criteria for diagnosis of GDM.Methods: Pregnant women between 24 to 28 weeks of gestation were subjected to non-fasting GCT. Capillary sample were also drawn simultaneously using Accu check active glucometer. These women were counselled to undergo a standard 75gram OGTT, within a week of recruitment.Results: According to IADPSG criteria, 17.6% (18/102) of our participants had GDM, as compared to 19.6% (20/102) by DIPSI criteria using venous samples, and 25.3% (25/99) by capillary sample method. Sensitivity and specificity of GCT using venous sample was 72.22% and 91.67%, and using capillary sample was 70.59% and 84.15% respectively. DIPSI criteria using venous samples wrongly labelled 8.3% women as GDM, and capillary samples wrongly labelled 15.9% women as GDM. More importantly DIPSI criteria using venous samples labelled 27.8% women as false-negative and capillary samples labelled 29.4% women as false-negative for GDM. Almost one quarter of women with GDM will be missed if DIPSI criteria is used as a universal screening modality.Conclusions: We suggest that the IADPSG criteria be used for diagnosis of GDM in antenatal women in India.

Background: Childbirth has a profound influence in a women’s life. One factor that has been more consistently identified as influencing the women’s physical and psychological symptoms following childbirth is the mode of birth.  This study aims at figuring out on women’s satisfaction with their mode of delivery and what difficulties they faced in the immediate postnatal period accordingly.Methods: All women who delivered between the period 1st July 2019 to 1st August 2019 were interviewed with a pretested semi structured questionnaire on postnatal day two. Patient was asked how much they were satisfied with their mode of delivery, immediate postnatal adjustments like ambulation, holding the baby first time, initiation of breastfeeding and pain score following different modes of delivery. The data was analysed to find out which mode of delivery made women more comfortable in the immediate postnatal period.Results: A total 97.1% women were satisfied with the support they got from health care professionals during labour. But when compared, spontaneous vaginal delivery group were satisfied with their mode of delivery (P-value-0.0005 highly significant) than the rest. Women who had vaginal delivery were ahead of caesarean group in terms of ambulation, holding the baby, initiation of breastfeeding and were well adjusted in their postnatal period.Conclusions: Authors conclude that women in our study were more satisfied with spontaneous vaginal delivery than caesarean section which was reflected in their immediate postnatal adjustments. As obstetricians’ authors need to understand the empowering effects of the psychological experience of vaginal delivery. The benefits of this process can be maximized through good communication skills and emotional support for women, enhancing their confidence to deliver normally so that caesarean section is done only when really indicated.
