Screening for perceived stress among pregnant women availing antenatal care at a tertiary care teaching institution in Kerala, India

Background: Stress during pregnancy can have serious adverse outcomes on the mother, the foetus and the new-born. It can lead to low-birth-weight, preterm births and neuro-psychological effects such as anxiety and depression during pregnancy and puerperium. This cross-sectional research aims to assess the severity of stress among postnatal women in Kerala. This study analysed socio-demographic, obstetric, family dynamics, neonatal characteristics and psychiatric determinants of postpartum stress using perceived stress scale (PSS) among postnatal women in a tertiary hospital in Kerala state, India.Methods: 119 women between 2 to 6 weeks of postpartum period were subjected to a pre-tested pre-structured standard questionnaire. Terminal illness, still birth delivery and comorbid psychiatric illness was excluded. Screening and diagnosis of postpartum stress was done based on perceived stress scale (PSS) and graded as mild 0-13, moderate 14-26, severe 27-40.Results: Study findings indicated a statistically significant association between postpartum stress and risk factors such as unplanned/unwanted pregnancy. The mean age of women was 27±4.8 years. Support from spouse and in-laws was a negative predictor of developing both postnatal stress and depression. Family income, education of couple and husbands’ occupations were non-determinant factors (p>0.05) in this study. Psychiatric illness in the family and past history of psychiatric illness also contributed to postnatal stress. The most important variable which influenced perceived stress during pregnancy was lengthier NICU stay. Even breastfeeding problems and associated neonatal issues worsened the stress scales significantly in the immediate postnatal period.Conclusions: This research concluded that stress detection and timely counselling along with mental and physical support will mitigate stress and postpartum depression

Effect of alloy chemistry and exposure conditions on the oxidation of titanium

Multiwall is a new thermal protection system concept for advanced space transportation vehicles. The system consists of discrete panels made up of multiple layers of foil gage metal. Titanium is the proposed candidate metal for multiwall panels in the reentry temperature range up to 675 C. Oxidation and embrittlement are the principal concerns related to the use of Ti in heat shield applications. The results of a broad study on the oxidation kinetics of several titanium alloys subjected to different exposure conditions are described. The alloys include commercially pure titanium, Ti-6Al-4V, and Ti-6Al-2Sn-4Zr-2Mo. Oxidation studies were performed on these alloys exposed at 704 C in 5-760 torr air pressure and 0 to 50% relative humidity. The resulting weight gains were correlated with oxide thickness and substrate contamination. The contamination depth and weight gains due to solid solutioning were obtained from microhardness depth profiles and hardness versus weight percent oxygen calibration data

Prevalence and determinants of postnatal depression in a tertiary care teaching institute in Kerala, India

Background: Pregnancy and childbirth produce a variety of physiological, psychological and social consequences. Attitudes toward pregnancy and childbirth vary from culture to culture. Prevalence estimates range from 13 to 19% in resource-rich settings and 11 to 42% in resource- limited settings PND has a significant impact on the mother, the family, her partner and mother-infant interaction. This research aims to aid the early diagnosis of postnatal depression and the socio-demographic, obstetric, family dynamics, neonatal characteristics and psychiatric determinants of depression using EPDS among postnatal women in a tertiary hospital in Kerala state, India.Methods: 119 women between 2 to 6 weeks of postpartum period were subjected to a pre-tested pre-structured standard questionnaire. Diagnosis of depression was made using the Edinburgh postnatal depression scale. Possible depression is values >13 or more are invariably associated with depression.Results: Young age at marriage (p-value 0.022), love marriage (p-value 0.040) and low social support inadequate relationship with the in-laws was significantly associated with PND (p-0.003). Low birth weight was a significant determinant of PND (p-value-0.018). Gender of the new-born, fear and preference towards any particular gender and order of female child in multiparous woman had no association in determining postnatal depression. Childcare stress (p-value-0.011), psychiatry history in family and personal history of depression and mothers with low self-esteem (p-value-0.001) had odds of developing postnatal depression in the study.Conclusions: Early screening of the women and counselling of women and their family will reduce the maternal morbidity and adverse child outcomes

Determinants and outcomes of caesarean delivery: elective versus emergency in a tertiary care teaching institute in Kerala, India

Background: Globally, the caesarean delivery rate is rising continuously, making caesarean one of the most common surgical procedures. The purpose was to analyse the determinants and maternofoetal outcomes in elective versus emergency caesarean sections in a tertiary care centre.Methods: All women, who gave birth by Caesarean deliveries done over a period of 1 year (January 2018-December 2018), were studied in Travancore Medical College in Kerala, India. Indications of caesarean, whether emergency or elective, medical morbidities, Gestational age at decision, birthweights and extended hospital stay and new-borns needed to resuscitate were looked into. The data was collected and analysed from the hospital registry.Results: Out of the 378 selected patients, 95 patients in group of elective and 283 emergency caesarean section were studied. The indications of emergency caesarean sections were failed induction, non-progression of labour, CPD, Previous caesarean in labour, foetal distress. The most frequent indicator for elective lower segment caesarean section (LSCS) was patient with previous LSCS not willing for vaginal birth, followed by breech presentation and high risk pregnancy ( BOH and ART). Younger mothers, gestational age remote from term, low-birth weight, and extended hospital stay were statistically significant in mothers undergoing emergency caesarean delivery. Fever, urinary tract infections, need for maternal and neonatal ventilation, blood transfusion, scar dehiscence were more common in the emergency caesarean group.Conclusions: The antenatal morbidity, low birth weights, decision taken preterm for salvaging the baby, postoperative complications and extended stay were more in the emergency caesarean when compared to elective caesarean
