Background: India plays an important role in global research on gestational diabetes mellitus (GDM), but a bibliometric assessment of this research is lacking., Objective: To provide a comprehensive analysis of Indian GDM research during the last 30 years using select bibliometric indicators., Methods: The Scopus international database was used to retrieve publication data, using a defined search strategy. The analysis focused on research output of Indian authors and organizations and their collaborations. The qualitative performance was assessed in terms of relative citation index and citations per paper (CPP)., Results: Overall, 100 countries participated in GDM research producing 13,193 publications during 1990-2019. India ranked ninth in global output (1182 publications, 3.1% share) and CPP of 18.6. Only 21.3% of publications had international collaboration and 9.4% were funded. Of the 235 organizations and 544 authors that participated in India's research on GDM, the top 50 organizations and authors contributed 53.8 and 36.4% to national publication share, respectively. The leading productive organizations were AIIMS, New Delhi, KEMH, Pune and PGIMER, Chandigarh, whereas the most productive authors were S. Kalra, V. Seshiah and C.S. Yajnik. Indian Journal of Endocrinology and Metabolism, Journal of Clinical and Diagnostic Research, Journal of Obstetrics and Gynecology of India and Diabetes Research and Clinical Practice were the most productive journals., Conclusions: Indian research on GDM is lagging behind other countries which have a similar disease burden. Increasing national and international collaborations, and active support of national and international funding agencies is urgently required to produce quality research on GDM., Supplementary Information: The online version contains supplementary material available at 10.1007/s13224-021-01444-7., Competing Interests: Conflict of interestNone., (© Federation of Obstetric & Gynecological Societies of India 2021.)

Pre-eclampsia is commonly associated with higher serum uric acid levels, which is known to increase vascular tone. A previous retrospective study established a positive correlation between raised serum uric acid levels and reduced incidence of post-spinal hypotension. However, until date, this correlation has not been prospectively evaluated in exclusively pre-eclamptic women. Pre-eclamptic parturients undergoing emergency cesarean delivery under subarachnoid block were included. Sample for measuring serum uric acid level was obtained prior to shifting patients for cesarean delivery. Following spinal anesthesia, we recorded episodes of hypotension (fall of mean arterial pressure more than 20% from baseline values), use of vasopressors, and intraoperative blood loss. Our primary objective was to study the association between maternal hyperuricemia and incidence of post-spinal hypotension. Our secondary objectives included amount of vasopressors administered to maintain targeted mean arterial pressure before delivery of the baby, intraoperative blood loss, and immediate neonatal outcome. A total of 95% parturients had hyperuricemia, with mean serum uric acid level being 6.94 ± 0.9 mg/dl. Incidence of post-spinal hypotension was significantly lower in women who had hyperuricemia as compared with those with normal serum uric acid levels (21% vs 75%; p = 0.015). Mean serum uric acid levels were significantly high (p = 0.001) in patients not requiring any vasopressors (7.2 ± 1.2 mg/dl) than in those requiring moderate (5.70 ± 0.79 mg/dl) to high dose (5.75 ± 0.77 mg/dl) of vasopressors. There is a high incidence of hyperuricemia in pre-eclamptic parturients. In these patients, elevated serum uric acid levels is associated with lower incidence of post-spinal hypotension and reduced need of vasopressors to maintain maternal blood pressure within a normal range.

Objective: Brain Age Index (BAI), calculated from sleep electroencephalography (EEG), has been proposed as a biomarker of brain health. This study quantifies night-to-night variability of BAI and establishes probability thresholds for inferring underlying brain pathology based on a patient's BAI., Methods: 86 patients with multiple nights of consecutive EEG recordings were selected from Epilepsy Monitoring Unit patients whose EEGs reported as within normal limits. While EEGs with epileptiform activity were excluded, the majority of patients included in the study had a diagnosis of chronic epilepsy. BAI was calculated for each 12-hour segment of patient data using a previously established algorithm, and the night-to-night variability in BAI was measured., Results: The within-patient night-to-night standard deviation in BAI was 7.5 years. Estimates of BAI derived by averaging over 2, 3, and 4 nights had standard deviations of 4.7, 3.7, and 3.0 years, respectively., Conclusions: Averaging BAI over n nights reduces night-to-night variability of BAI by a factor of n, rendering BAI a more suitable biomarker of brain health at the individual level. A brain age risk lookup table of results provides thresholds above which a patient has a high probability of excess BAI., Significance: With increasing ease of EEG acquisition, including wearable technology, BAI has the potential to track brain health and detect deviations from normal physiologic function. The measure of night-to-night variability and how this is reduced by averaging across multiple nights provides a basis for using BAI in patients' homes to identify patients who should undergo further investigation or monitoring., Competing Interests: Declaration of Competing Interest Dr. Thomas declares the following conflicts: 1) Patent and license for a technology using ECG to assess sleep quality and sleep apnea, licensed to MyCardio, LLC; 2) Patent and license for an auto-CPAP algorithm, licensed to DeVilbiss-Drive. 3) Unlicensed [patent to treat central sleep apnea with low concentration CO2 with positive airway pressure. 4) Consultant to Jazz Pharmaceuticals; 5) General sleep medicine consulting for GLG Councils and Guidepoint Global., (Copyright © 2020 International Federation of Clinical Neurophysiology.

The brain age index (BAI) measures the difference between an individual's apparent "brain age" (BA; estimated by comparing EEG features during sleep from an individual with age norms), and their chronological age (CA); that is BAI = BA-CA. Here, we evaluate whether BAI predicts life expectancy. Brain age was quantified using a previously published machine learning algorithm for a cohort of participants ≥40 years old who underwent an overnight sleep electroencephalogram (EEG) as part of the Sleep Heart Health Study (n = 4877). Excess brain age (BAI >0) was associated with reduced life expectancy (adjusted hazard ratio: 1.12, [1.03, 1.21], p = 0.002). Life expectancy decreased by -0.81 [-1.44, -0.24] years per standard-deviation increase in BAI. Our findings show that BAI, a sleep EEG-based biomarker of the deviation of sleep microstructure from patterns normal for age, is an independent predictor of life expectancy., (Copyright © 2019 Elsevier Inc.

Background: Near miss (NM) concept has led to a more comprehensive and better assessment of effect of care on maternal health. It indicates the degree of organ function failure in the wide spectrum of severity., Methods: This was a prospective observational study conducted from July 2015 to Feb 2016. Among women with potentially life-threatening conditions (PLTCs), those fulfilling one or more WHO NM criteria were included and followed up till the final outcome (NM or death). Various critical interventions done in them were associated with the final outcome. Standardized mortality ratio (SMR) was calculated for assessment of overall quality of health care provided., Results: One thousand seven hundred and thirty-nine patients had PLTCs of which 174 (10%) patients were identified as NM. Of 174 patients, 116 patients (66.66%) were discharged in stable condition (group A) and 58 patients (33.34%) died (group B). Hemorrhage (31.8%) was the most frequent complication in group A followed by hypertensive disorders (18.1%) and severe anemia (11.2%). The two most common causes of maternal mortality were hypertensive disorders (27.6%) and hemorrhage (24.1%). Only two critical interventions (assisted ventilation and massive blood transfusion) had significant association with the final outcome. SMR of our center was 1.187 indicating adequate quality of provision of care to the patients., Conclusion: Hemorrhage and hypertensive disorders were the two most common causes of NM and deaths highlighting the importance of their prompt diagnosis and vigorous management. Periodic SMR calculation can be used as an audit to guide us in improving the overall status of maternal health., Competing Interests: Conflict of interestAll authors declare that they have no conflicts of interest., (© Federation of Obstetric & Gynecological Societies of India 2019.)

Purpose: Raised serum uric acid, a marker of oxidative stress, is known to increase vascular tone and depress myometrial contractility. A rise in serum uric acid levels has also been reported during labor, warranting its correlation with post-spinal hypotension and uterine tone., Methods: Serum UA sample was drawn from enrolled healthy, laboring parturients. Of these, 100 women who required emergency cesarean delivery were re-sampled prior to surgery. Following spinal anesthesia we recorded episodes of hypotension (MAP < 80% of baseline), use of vasopressors and supplemental uterotonics. The primary outcome was maternal hyperuricemia (1SD > appropriate for gestation age) and its correlation with post-spinal hypotension. Secondary outcomes were total vasopressors used, duration of labor and its effect on uric acid levels, uterine tone and neonatal outcome., Results: Hyperuricemia was observed in 33% of parturients. On comparing with women showing normal uric acid levels, hyperuricemic parturients experienced significantly lower incidence of post-spinal hypotension (45.5% vs. 67.2%; p value = 0.04) and lower vasopressor usage (p value = 0.06). Clinically, an increased use of supplemental uterotonics in these parturients was noted (p = 0.20). The duration of labor had no impact on uric acid levels. Neonatal outcome was unaffected., Conclusions: In healthy, normotensive parturients undergoing emergency cesarean delivery, maternal hyperuricemia is associated with lower incidence of post-spinal hypotension and reduced need of vasopressors. Elevated serum uric acid levels may also be associated with decreased uterine tone, necessitating greater requirement of supplemental uterotonics. However, further prospective trials are needed to strongly establish this association.

Objective: To assess the applicability of WHO Maternal Severity Score (MSS) and Maternal Severity Index (MSI) Model in near miss (NM) obstetric patients METHODS: It was a prospective observational study conducted at a tertiary health care center from July 2015 to Feb 2016. All patients fulfilling one or more WHO NM criteria were included. MSS and MSI were calculated for all NM patients on admission. They were then followed up till the final outcome (NM or death). Each NM parameter, system-wise MSS, total MSS and MSI were then associated with the final outcome., Results: Of 4822 patients, 1739 had potentially life-threatening conditions of which 174 were identified as NM. The average MSS and MSI of patients who remained NM was 4.41 and 11.67%, respectively, and those who died was 9.47 and 58.16%, respectively. Both were found to be significantly associated with the outcome (p < 0.001). MSI had good accuracy for maternal death prediction in women with markers of organ dysfunction (AUROC - 0.838 [95% CI 0.766-0.910]). However, of 25 NM criteria, only 17 NM criteria and 3 system dysfunctions (cardiovascular, respiratory and neurological) were found to associate significantly with the outcome., Conclusion: MSS and MSI act as good prognostic tools to assess the severity of maternal complications and estimate the probability of death in NM patients. As all NM parameters are not equally predictive of severity of maternal morbidity, different scores per NM parameter and system should be assigned while calculating MSS for better prognostication.

Objective: To improve the rates of first hour initiation of breastfeeding in neonates born through cesarean section from 0 to 80% over 3 months through a quality improvement (QI) process., Design: Quality improvement study., Setting: Labor Room-Operation Theatre of a tertiary care hospital., Participants: Stable newborns ≥35 weeks of gestation born by cesarean section under spinal anesthesia., Procedure: A team of nurses, pediatricians, obstetricians and anesthetists analyzed possible reasons for delayed initiation of breastfeeding by Process flow mapping and Fish bone analysis. Various change ideas were tested through sequential Plan-Do-Study-Act (PDSA) cycles., Outcome Measure: Proportion of eligible babies breast fed within 1 hour of delivery., Results: The rate of first-hour initiation of breastfeeding increased from 0% to 93% over the study period. The result was sustained even after the last PDSA cycle, without any additional resources., Conclusion: A QI approach was able to accomplish sustained improvement in first-hour breastfeeding rates in cesarean deliveries.

Retained surgical sponges in the peritoneal cavities are an infrequent operative/surgical complication and an error which is avoidable. The unfortunate situation of forgotten or missed foreign bodies after any surgical procedure may lead to medico legal problems. Though gossypiboma can be found at any operative site but intraperitoneal cavity is the most frequent site reported in literature. Over a period of three years, June 2009-2012, we conducted retrospective analysis of case summaries of eight patients who underwent re-laparotomy for retained surgical sponge at our institute. Pre operative diagnosis was made in 7out of 8 patients, 5 of whom underwent re-laparotomy and one had sponge removed through the caesarean incision, while in another it was removed per-vaginum through the open vault (post hysterectomy). In one patient, gossypiboma was an incidental finding on laparotomy done for adnexal mass. There was no mortality in any of the cases.

Objective: This study was undertaken to analyze the maternal and perinatal outcome in women with prosthetic heart valves on different anticoagulant regimens., Study Design: A retrospective chart review of pregnancies in 40 women with mechanical valve prostheses at a tertiary referral centre from 1997 to 2010. The main outcome measures were major maternal complications and perinatal outcome., Results: The valves replaced were mitral (67.5%), aortic (15.0%), or both (17.5%). Forty-nine pregnancies (72.1%) resulted in live births, 3(4.4%) had stillbirths, and 13(19.1%) had spontaneous abortions and 1(1.4%) underwent therapeutic abortions. The live birth rate was higher in women on heparin (78.3%) compared with those on warfarin (66.9%). There were 2 maternal deaths due to acute mitral valvular thrombosis while on acenocoumarol in the second trimester. Hemorrhagic complications occurred in 3 patients on heparin in the postpartum period, 2 of whom required transfusion. In addition one patient who was on acenocoumarol developed secondary hemorrhage., Conclusion: No anticoagulant regimen can be said to be entirely safe for use during pregnancy as there is a degree of risk with each regimen. Further larger studies are needed to come up with sufficient evidence-based recommendations for the best possible management of such patients to reduce the maternal risks after mechanical heart valve replacement without compromising fetal outcome., (Copyright © 2011 Elsevier Ireland Ltd.

Objectives and Methods: In 100 anovulatory infertile women with polycystic ovary syndrome attending the infertility clinic of this institute, transvaginal ultrasound findings of ovaries were correlated with both clinical and hormonal parameters using Chi-square test., Results: All women in the study had oligomenorrhea or amenorrhea, 70% had hirsutism and more than half were obese. On transvaginal ultrasound, ovarian volume was more than 10 cm3 in all, 90% had more than 10 follicles in each ovary, 75% had stromal thickness more than 1 cm and more than half had increased stromal echogenicity. Seventy percent had high testosterone levels and 60% were detected to have insulin resistance. Ovarian volume correlated positively with body mass index, waist/hip ratio and menstrual cycle irregularity (p < 0.05). The correlation between ovarian size, LH/FSH ratio and hyperinsulinemia was highly significant (p < 0.005), but was low for serum androgens and also hirsutism. Number of follicles per ovary correlated positively with body mass index, menstrual irregularity (p < 0.01), insulin resistance as well as androgens (p < 0.005). Positive predictive value of ovarian follicle number was 100% for insulin resistance as well as D4 androstenedione. Increased stromal thickness also showed 70% positive prediction for clinical parameters, 66% for insulin resistance and 82% for serum D4 androstenedione. Contrary to the other ultrasound parameters of polycystic ovary, stromal echogenicity did not significantly correlate with any of the clinical or hormonal parameters except serum testosterone., Conclusion: Transvaginal ultrasonography of the ovaries confirms the clinical profile and also gives an insight to the hormonal milieu of the women with PCOS.
