    Background: Several studies in the past two decades have proved beyond doubt that there is a high prevalence of hypovitaminosis D worldwide including India which has almost taken the shape of a pandemic. The study aims to determine the prevalence of hypovitaminosis D in the pregnant population of Delhi and its correlation with gestational diabetes mellitus.Methods: This prospective cross sectional observational study was conducted at the Department of Obstetrics and Gynaecology, Postgraduate Institute of Medical Education and Research (PGIMER), Dr R.M.L Hospital, New Delhi over a period of 1 year and 4 months. Four hundred term patients were enrolled randomly from amongst the patients admitted in labor room or antenatal ward at PGIMER, Dr. Ram Manohar Lohia Hospital who fulfilled the inclusion and exclusion criteria. 3-4ml of fasting blood samples were collected of all the enrolled women and were analysed for total serum calcium levels and serum vitamin D levels. History of presence of gestational diabetes mellitus was noted along with any treatment history. The 25(OH)D levels for each subject was recorded and correlation of vitamin D levels with gestational diabetes mellitus was analysed. Statistical analysis was done using ANOVA/ Kruska Wallis test and Chi-Square test/ Fisher’s exact test. A p value of <0.05 was considered statistically significant.Results: The overall prevalence of vitamin D deficiency in the present study was 86.25%. The overall mean serum vitamin D level was 14.06±9.43 ng/ml. Thirty five out of 37 GDM patients had hypovitaminosis D i.e. 94.59%. The prevalence of hypovitaminosis D among non-GDM population was 85.40%. The association between GDM and Vitamin D deficiency was statistically non- significant in the present study with p value=0.186.Conclusions: There is a very high prevalence of hypovitaminosis D in pregnant females attending present institute i.e. 86.25%. Although 94.59 % of Gestational Diabetes Mellitus patients had vitamin D deficiency, there is no statistically significant association between Gestational diabetes mellitus and serum vitamin D levels

    Gloxaline have occupied a unique position in heterocyclic chemistry, and its derivatives have attracted considerable interests in recent years for their versatile properties in chemistry and pharmacology. Gloxaline is nitrogen-containing heterocyclic ring which possesses biological and pharmaceutical importance. Thus, Gloxaline compounds have been an interesting source for researchers for more than a century.   The Gloxaline ring is a constituent of several important natural products, including purine, histamine, histidine, and nucleic acid. Being a polar and ionisable aromatic compound, it improves pharmacokinetic characteristics of lead molecules and thus is used as a remedy to optimize solubility and bioavailability parameters of proposed poorly soluble lead molecules. There are several methods used for the synthesis of gloxaline -containing compounds, and also their various structure reactions offer enormous scope in the field of medicinal chemistry. The Gloxaline derivatives possess extensive spectrum of biological activities such as antibacterial, anticancer, antitubercular, antifungal, analgesic, and anti-HIV activities. This paper aims to review the biological activities of gloxaline during the past years

    A Double Truncated Binomial Model to Assess Psychiatric Health through Brief Psychiatric Rating Scale: When is Intervention Useful?

    Get PDF
    A double truncated binomial distribution model with ‘u’ classes truncated on left and ‘v’ classes truncated on right is introduced. Its characteristics, namely, generating functions; and the measures of skewness and kurtosis have been obtained. The unknown parameter has been estimated using the method of maximum likelihood and the method of moments. The confidence interval of the estimate has been obtained through Fisher’s information matrix. The model is applied on cross sectional data obtained through Brief Psychiatric Rating Scale (BPRS) administered on a group of school going adolescent students; and the above-mentioned characteristics have been evaluated. An expert, on the basis of the BPRS score values, suggested an intervention program. The BPRS scores of the students who could be administered the intervention program lied in a range (which was above the lowest and below the highest possible values) suggested by the expert. Whereas the complete data suggested the average number of problem areas is four (which was not in consonance with the observations given by the expert), the double truncated model suggested the number of such areas as five which was consistent with the observations made by the expert. This establishes the usefulness of double truncated models in such scenarios

    Role of dual biomarkers and uterine artery doppler study in predicting PIH and IUGR in antenatal patients registered in a tertiary care centre

    Background: The incidence of IUGR is between 3 to 7%, whereas that of Hypertensive disorders of pregnancy is about 10% of pregnant women around the world. These conditions are associated with a high rate of perinatal morbidity and mortality, posing a need for the detection of the potential causes of maternal and foetal morbidity and mortality and for the prediction of these conditions early during pregnancy.Methods: Patients with first antenatal visit before 10 weeks gestation underwent routine NT scan between 11–13 weeks with bilateral UAD-RI of the maternal uterine arteries. The placental volume was assessed. Serum dual biomarker test (β hCG and PAPP-A) was performed after this scan and analysed as multiples of median (MoM). Blood pressure was recorded at every ANC visit till 2 weeks after delivery. Neonatal head and chest circumference, birth length and weight were recorded.Results: The mean values of PAPP-A levels of Non-PIH and PIH groups were 1.32±0.91 MoM and 0.68±0.39 MoM respectively, showing statistically significant difference.  The serum PAPP-A levels showed statistically significant difference between Non-IUGR and IUGR groups (1.24±0.87 MoM and 0.46±0.20 MoM respectively).Conclusions: In our study, PAPP-A level is observed as a good indicator for possible prediction of PIH and IUGR whereas levels of β hCG and UAD-RI were not good predictors. The role of Placental volume in prediction of IUGR needs to be explored further with larger sample size. Future studies are needed with a larger group with inclusion of measurement of PI values

    Malaria in Pregnancy

    Malaria infection during pregnancy is an important public health problem with substantial risks to both the mother and foetus. Pregnant women are the most vulnerable group of malaria‐associated morbidity and mortality. A pregnant woman has an increased risk (up to four times) of getting malaria and twice the chances of dying from malaria, compared to a non‐pregnant adult, becuase the immune system is partially suppressed during pregnancy. Malaria in pregnancy not only affects the mother but also has a dangerous sequel for the developing foetus, resulting in premature delivery or intrauterine growth retardation. Diagnosis of malaria in pregnancy remains a challenge due to the low parasite density and placental sequestration of Plasmodium falciparum. Thus, there is an urgent need for new diagnostic methods to detect malarial parasites in the pregnant women. Though antimalarial drugs are available, which can be safely given in the pregnancy, increasing drug resistance of malarial parasite may pose a big problem in the future. In this chapter, we review the burden of pregnancy‐associated malaria (PAM), its pathogenesis, diagnostic issues during pregnancy and recent guidelines for chemoprophylaxsis and treatment

    Background: Uterine fibroids constitute a substantial bulk of patients presenting to Gynaecology department. Many newer imaging modalities have evolved for their correct evaluation, but in a developing country like India, ultrasound is still being used as a screening as well as diagnostic modality. So, this study was done to compare ultrasound and magnetic resonance imaging for evaluation of uterine fibroids in terms of their sensitivity, specificity Trans vaginal  and positive predictive value using Histopathology as a gold standard so as to improvise on current clinical practices in this country.Methods: An ethically approved prospective study was done upon 50 patients with suspected uterine masses at SMS Hospital Jaipur. All included patients underwent Trans vaginal Ultrasound (TVS) and Magnetic resonance imaging (MRI) and were accordingly treated surgically. Histopathology report was traced postoperatively. Data was collected and subjected to various statistical tests including Cohen’s kappa.Results: Most of the patients were <50 years and presented with complains of pain abdomen. Among total 50 cases, the sensitivity of TVS and MRI was 44% and 92%, specificity was 96% and 88%, PPV was 91.67% and 88.46%, NPV was 63.16% and 91.67% respectively, kappa was 0.40 and 0.80 i.e. agreement between TVS and MRI v/s HPE was 40% and 80% respectively. The diagonal agreement between transvaginal USG and MRI, was 63%.Conclusions: TVS is a good screening modality but MRI is definitely better for proper characterization and localization of fibroids enabling clinicians to select the most appropriate management in everyday clinical practice
