Long-Term Predictors of Gestational Hypertension: Placental Growth Factor, Pregnancy-Associated Plasma Protein-A and Free Beta-Hcg Versus Mean Arterial Pressure and Uterine Artery Doppler Versus a Combination of Both: A Comparative Study.

Background: According to WHO, hypertensive disease is the leading cause of direct maternal mortality accounting for 10-25% in developing countries (James in Heart, 90(12):1499-504). This study compares the combinations of mean arterial pressure (MAP) and uterine artery doppler (UAD) versus serum-free ß HCG, pregnancy-associated plasma protein-A, and placental growth factor (PlGF) versus a combination of all variables at 11 to 13+6 as long-term predictors of pregnancy-induced hypertension (PIH). Materials and Methods: A prospective, observational cohort study recruited 97 primigravidae at 11 to 13+6 weeks gestation at GMCH. Follow-up was done at 32-34 weeks and before delivery. Development of PIH, mode of delivery, birthweight, maternal and fetal adverse outcomes were documented, analyzed and compared among three groups. In Group A-biophysical markers, Group B-biochemical markers and in Group C all variables were used. Results: The mean age, maternal weight, height and BMI of patients developing gestational hypertension were 30 ± 5 years, 64.3 ± 12.5 kg, 155.8 ± 5.5 cm and 26.4 ± 4.1, respectively. Out of the 3, Group C is the best screening test for predicting the overall chance of development of gestational hypertension with a sensitivity of 97.37% and specificity of 38.98% (p < 0.0001). A mild negative correlation is seen between PlGF levels and severity of PIH (p-0.0382). Conclusion: MAP and UAD can be easily incorporated into the infrastructure of most hospitals. If the biochemical test kits are made available at a low cost through available programs such as JSSK, it can bring down the MMR by preventing gestational hypertension.

An investigation into the role of Notch signaling, altered angiogenesis, and inflammatory-induced preterm delivery and related complications in Northeast Indian patients.

INTRODUCTION: Notch signaling is crucial during pregnancy with ability to regulate angiogenesis and inflammatory response. Considering the enigmatic importance of Notch signaling in pregnancy including placenta development, gestational disorders and adverse pregnancy; we performed experimental analysis to identify the Notch receptor-ligands association with Preterm delivery (PTD) and linked complication. METHOD: A total of 245 cases [Term n = 135 and Preterm n = 110] were enrolled for the study from Northeast Indian Population. The differential mRNA expression of Notch receptors , ligands, its downstream target Hes1 and Immune markers (IL-10, IL-12 and TNF-α) was studied by real time polymerase chain reaction. Further the protein study of Notch1 and 4, Hes1, VEGF and TNF-α was performed by immunofluorescence. RESULTS: Placental mRNA expression of all the four notch receptors [Notch1 = 2.15 ± 1.02 fold, Notch2 = 6.85 ± 2.70 fold, and Notch3 = 1.74 ± 0.90 fold and Notch4 = 14.15 ± 6.72 fold]; ligands [JAG1 = 2.71 ± 1.22, JAG2 = 4.41 ± 2.31, DLL1 = 3.55 ± 1.38, DLL3 = 4.31 ± 2.82 and DLL4 = 3.07 ± 1.30 folds] and downstream target [Hes1 = 6.09 ± 2.89 folds] was elevated in PTD cases compared to Term delivery (TD) cases. The mRNA expression of pro-inflammatory marker (IL-12 = 3.99 ± 1.02 fold and TNF-α = 16.83 ± 2.97), was upregulated. The upregulated expression of Notch1(p < 0.001), JAG1 (p = 0.006), JAG2 (p = 0.009), DLL1 (p = 0.001), DLL4 (p < 0.001) Hes1 (p < 0.001), TNF-α (p < 0.001) and IL-12 (p = 0.006) were associated with the baby death; and Notch4 significantly inversely correlated with low birth weight (LBW). Consistently higher protein level expression of Notch1, Hes1, VEGFA and TNF-α was observed in preterm with highest expression in negative outcome cases. DISCUSSION: To conclude, the increased Notch1 expression and angiogenesis linked inflammation holds key in understanding the pathogenesis of PTD and linked complications and underlines its potential as therapeutic target for PTD interventions.

Outcome of Guillain-Barré Syndrome (GBS) During Peripartum Period: A Hospital-Based Observational Study.

Objective: 1. To study the clinical profile, progression and outcome of GBS during peripartum period in a tertiary care hospital. 2. To identify the determinants of outcome in GBS during peripartum period. Background: Guillain-Barré Syndrome (GBS) is an acute, autoimmune disorder of the peripheral nervous system triggered by a bacterial or viral infection or other antecedent events. Modern day critical care has dramatically improved the outcome of GBS. GBS during pregnancy is rare with an annual incidence of 2.8/100,000 population. Pregnancy itself is a life-threatening condition and full of complications. GBS during pregnancy makes its more complicated in terms of both maternal and fetal care during peripartum period. Methods: This was a prospective study conducted by the Department of Neurology, Gauhati Medical College including 36 patients of GBS presenting during peripartum period in between December 2019 and November 2021. Their clinical and electrophysiological features were analyzed. Hughes grading, EGRIS, mEGOS, MRC sum score were used. The fetal outcome was observed and patients were followed up for GBS outcome at 3 months and 6 months. Results: The mean age of patients was 25.97 years. AIDP was the most common subtype found in 21 (58.33%) patients followed by AMAN in 7 (19.4%), AMSAN in 3 (8.33%). In 3 cases NCS was equivocal and in 3 cases inexcitable. Respiratory distress was found in 13 (36.1%) cases, out of which 4 (11.1%) required mechanical ventilation and 1 (2.8%) died. The pre-term birth rate and stillbirth rate were 35.7% (n = 10) and 8.33% (n = 3), respectively with 66.7% (n = 24) spontaneous vaginal delivery(SVD). At 3 month 26 (72.2%) had complete recovery. 5 (13.9%) and 4 (11.1%) had partial and poor recovery, respectively. 78.9% of primigravidae had complete recovery in comparison to 64.7% in multigravidae indicating better outcome in primigravidae in this study. Conclusion: The outcome of GBS during peripartum period is favorable. Primigravidae are more commonly affected but have better outcome than the multigravidae. The risk of developing GBS in pregnancy decreases significantly after delivery and is minimal after 2 weeks. GBS is not an indication for LSCS. Stillbirth rate and preterm birth rate is higher in pregnancy associated with GBS without fearsome neonatal complications.

Relationship between anaemia, coagulation parameters during pregnancy and postpartum haemorrhage at childbirth: a prospective cohort study.

OBJECTIVES: To investigate the association between coagulation parameters and severity of anaemia (moderate anaemia: haemoglobin (Hb) 7-9.9 g/dL and severe anaemia: Hb <7 g/dL) during pregnancy and relate these to postpartum haemorrhage (PPH) at childbirth. DESIGN: A prospective cohort study of pregnant women recruited in the third trimester and followed-up after childbirth. SETTING: Ten hospitals across four states in India. PARTICIPANTS: 1342 pregnant women. INTERVENTION: Not applicable. METHODS: Hb and coagulation parameters: fibrinogen, D-dimer, D-dimer/fibrinogen ratio, platelets and international normalised ratio (INR) were measured at baseline. Participants were followed-up to measure blood loss within 2 hours after childbirth and PPH was defined based on blood loss and clinical assessment. Associations between coagulation parameters, Hb, anaemia and PPH were examined using multivariable logistic regression models. OUTCOMES MEASURES: Adjusted OR with 95% CI. RESULTS: In women with severe anaemia during the third trimester, the D-dimer was 27% higher, mean fibrinogen 117 mg/dL lower, D-dimer/fibrinogen ratio 69% higher and INR 12% higher compared with women with no/mild anaemia. Mean platelets in severe anaemia was 37.8×109/L lower compared with women with moderate anaemia. Similar relationships with smaller effect sizes were identified for women with moderate anaemia compared with women with no/mild anaemia. Low Hb and high INR at third trimester of pregnancy independently increased the odds of PPH at childbirth, but the other coagulation parameters were not found to be significantly associated with PPH. CONCLUSION: Altered blood coagulation profile in pregnant women with severe anaemia could be a risk factor for PPH and requires further evaluation.

Risk factors for maternal mortality among 1.9 million women in nine empowered action group states in India: secondary analysis of Annual Health Survey data.

OBJECTIVE: To examine the risk factors for pregnancy-related death in India's nine Empowered Action Group (EAG) states. DESIGN: Secondary data analysis of the Indian Annual Health Survey (2010-2013). SETTING: Nine states: Assam, Bihar, Chhattisgarh, Jharkhand, Madhya Pradesh, Odisha, Rajasthan, Uttar Pradesh and Uttarakhand. PARTICIPANTS: 1 989 396 pregnant women. METHODS: Maternal mortality ratio (MMR), overall and for each state, with 95% CI was calculated. Stepwise multivariable logistic regression was used to investigate the association of risk factors with maternal mortality. Area under the receiver-operating characteristic (AUROC) curve was used to assess the prediction of the model. OUTCOME MEASURES: MMR adjusted for survey design, adjusted OR (aOR)with 95% CI and C-statistic with 95% CI. RESULTS: MMR calculated for the nine states was 383/100 000 live births (95% CI 346 to 423 per 100 000). Age exhibited a U-shaped association with maternal mortality. Not having a health scheme and belonging to a scheduled caste or scheduled tribe group were significant risk factors for maternal death with aOR of 2.72 (95% CI 2.41 to 3.07), 1.10 (95% CI 1.02 to 1.18) and 1.43 (95% CI 1.31 to 1.56), respectively. Socioeconomic status and rural residence were not associated with maternal mortality after adjusting for access to a healthcare facility. Complications of pregnancy and medical comorbidities were the strongest risk factors for maternal death (aOR 50.2, 95% CI 44.5 to 56.6). Together, the risk factors identified accounted for 89% (95% CI 0.887 to 0.894) of the AUROC. CONCLUSIONS: Maternal mortality in India's EAG states greatly exceeds the national average. The identified risk factors demonstrate the importance of improving the quality of pregnancy care. Notably, the study showed that the risk conferred by poor socioeconomic status could be mitigated by universal access to healthcare during pregnancy and childbirth.

Unsafe abortion and abortion-related death among 1.8 million women in India.

INTRODUCTION: Unsafe abortion is a preventable cause of maternal mortality. While studies report high number of abortions in India, the population-level rates of unsafe abortion and their risk factors are not well understood. Our objective was to analyse the rates of and risk factors for unsafe abortion and abortion-related maternal death in India. METHODS: We conducted a secondary analysis of data from 1 876 462 pregnant women aged 15-58 years from nine states in the Indian Annual Health Survey (2010-2013). We calculated the rate of unsafe abortion and abortion-related mortality with 95% CI. Multivariable logistic regression models examined the associations of sociodemographic characteristics, health seeking behaviours and family planning with unsafe abortion and abortion-related mortality. RESULTS: There were 89 447 abortions among 1 876 462 pregnant women in 2007-2011 (4.8%; 95% CI 4.8 to 4.9). Of these, 58 266 were classified as unsafe (67.1%; 95% CI 66.7 to 67.5). There were 253 abortion-related maternal deaths (0.3%; 95% CI 0.2 to 0.3). Factors associated with unsafe abortion: maternal age 20-24 years (adjusted OR (aOR): 1.13; 95% CI 1.09 to 1.18), illiteracy (aOR: 1.48; 95% CI 1.39 to 1.59), rural residence (aOR: 1.26; 95% CI 1.21 to 1.32), Muslim religion (aOR: 1.16; 95% CI 1.12 to 1.22), Schedule caste social group (aOR: 1.08; 95% CI 1.04 to 1.12), poorest asset quintile (aOR: 1.45; 95% CI 1.38 to 1.53), antenatal care (aOR: 0.69; 95% CI 0.67 to 0.72), no surviving children (aOR: 1.30; 95% CI 1.16 to 1.46), all surviving children being female (aOR: 1.12; 95% CI 1.07 to 1.17), use of family planning methods (aOR: 0.69; 95% CI 0.66 to 0.71). Factors associated with abortion-related deaths: maternal age 15-19 (aOR: 7.79; 95% CI 2.73 to 22.23), rural residence (aOR: 3.28; 95% CI 1.76 to 6.11), Schedule tribe social group (aOR: 4.06; 95% CI 1.39 to 11.87). CONCLUSION: Despite abortion being legal, the high estimated prevalence of unsafe abortion demonstrates a major public health problem in India. Socioeconomic vulnerability and inadequate access to healthcare services combine to leave large numbers of women at risk of unsafe abortion and abortion-related death.

Stillbirth among women in nine states in India: rate and risk factors in study of 886,505 women from the annual health survey.

OBJECTIVES: To assess the rate of stillbirth and associated risk factors across nine states in India. DESIGN: Secondary analysis of cross-sectional data from the Indian Annual Health Survey (2010-2013). SETTING: Nine states in India: Madhya Pradesh, Chhattisgarh, Rajasthan, Uttarakhand, Jharkhand, Odisha, Bihar, Assam and Uttar Pradesh. PARTICIPANTS: 886 505 women, aged 15-49 years. MAIN OUTCOME MEASURES: Stillbirth rate with 95% CI. Adjusted OR to examine the associations between stillbirth and (1) socioeconomic, behavioural and biodemographic risk factors and (2) complications in pregnancy (anaemia, eclampsia, other hypertensive disorders, antepartum and intrapartum haemorrhage, obstructed labour, breech presentation, abnormal fetal position). RESULTS: The overall rate of stillbirth was 10 per 1000 total births (95% CI 9.8 to 10.3). Indicators of socioeconomic deprivation were strongly associated with an increase in stillbirth: rural residence (adjusted OR (aOR) 1.27, 95% CI 1.16 to 1.39), female illiteracy (aOR 1.43, 95% CI 1.17 to 1.74), low socioeconomic status (aOR 2.42, 95% CI 1.82 to 3.21), schedule caste background (aOR 1.11, 95% CI 1.04 to 1.19) and woman not in paid employment (aOR 1.15, 95% CI 1.07 to 1.24). Women from minority religious groups were at higher risk than the Hindu majority (Muslim (aOR 1.33, 95% CI 1.25 to 1.43); Christian (aOR 1.42, 95% CI 1.19 to 1.70)). While a few women smoked (<1%), around 9% reported chewing tobacco, which was associated with an increased odds of stillbirth (aOR 1.11, 95% CI 1.02 to 1.21). Adverse pregnancy and birth characteristics were also associated with stillbirth: antenatal care visits <4 (aOR 1.08, 95% CI 1.01 to 1.15), maternal age <25 years (aOR 1.29, 95% CI 1.21 to 1.37) and ≥35 years (aOR 1.16, 95% CI 1.04 to 1.29), multigravida (aOR 3.06, 95% CI 2.42 to 3.86), multiple pregnancy (aOR 1.77, 95% CI 1.47 to 2.15), assisted delivery (aOR 3.45, 95% CI 3.02 to 3.93), caesarean section (aOR 1.73, 95% CI 1.58 to 1.89), as were pregnancy complications (aOR 1.42, 95% CI 1.33 to 1.51). CONCLUSION: India is an emerging market economy experiencing a rapid health transition, yet these findings demonstrate the marked disparity in risk of stillbirth by women's socioeconomic status. Tobacco chewing and maternal and fetal complications were each found to be important modifiable risk factors. Targeting the 'at-risk' population identified here, improved recording of stillbirths and the introduction of local reviews would be important steps to reduce the high burden of stillbirths in India.
