Lot-to-lot consistency of a hexavalent DTwP-IPV-HB-PRP∼T vaccine and non-inferiority to separate DTwP-HB-PRP∼T and IPV antigen-matching vaccines at 6-8, 10-12, and 14-16 weeks of age co-administered with oral rotavirus vaccine in healthy infants in India: A multi-center, randomized, controlled study.

Background: Combination vaccines reduce the number of pediatric injections but must be as safe, immunogenic, and effective as each of the individual vaccines given separately. Additionally, consistency in manufacturing lots is essential for WHO prequalification. This study aimed to establish the lot-to-lot consistency of a fully liquid, hexavalent diphtheria (D)-tetanus (T)-whole-cell pertussis (wP)-inactivated poliovirus (IPV)-hepatitis B (HB)-Haemophilus influenzae b (PRP-T) (DTwP-IPV-HB-PRP∼T) vaccine and to demonstrate non-inferiority to licensed DTwP-HB-PRP∼T and IPV vaccines. Methods: A Phase III, randomized, active-controlled, and open-label study was conducted at multiple centers across India. Healthy infants who had received a birth dose of oral poliovirus vaccine and hepatitis B vaccine received one of three lots of DTwP-IPV-HB-PRP∼T or separate DTwP-HB-PRP∼T and IPV vaccines at 6-8, 10-12, and 14-16 weeks of age. Oral rotavirus vaccine was co-administered at 6-8 weeks of age and 10-12/14-16 weeks of age. DTwP-IPV-HB-PRP∼T lot-to-lot consistency and non-inferiority (pooled DTwP-IPV-HB-PRP∼T) versus DTwP-HB-PRP∼T and IPV post-third dose were assessed using seroprotection rates (anti-D, anti-T, anti-HBs, anti-PRP, anti-polio 1, 2, 3) and adjusted geometric mean concentrations (anti-PT, anti-FIM). Safety was assessed by parental reports. Results: Lot-to-lot consistency was demonstrated for DTwP-IPV-HB-PRP∼T and non-inferiority versus DTwP-HB-PRP∼T and IPV was confirmed with 95% CIs for seroprotection rate differences and adjusted geometric mean concentration ratios within pre-defined clinical margins. Pooled seroprotection rate was ≥ 99.7% for anti-D ≥ 0.01 IU/mL, anti-T ≥ 0.01 IU/mL, anti-HBs ≥ 10 mIU/mL, anti-PRP ≥ 0.15 µg/mL, and anti-polio 1, 2, and 3 ≥ 8 (1/dil) and vaccine response rate was 83.9% for anti-PT and 97.7% for anti-FIM. There were no safety concerns. Conclusions: Immunogenicity of three lots of the fully liquid DTwP-IPV-HB-PRP∼T vaccine was consistent and non-inferior to licensed comparators following vaccination at 6-8, 10-12, and 14-16 weeks of age. There were no safety concerns and no evidence of any effect of co-administration with rotavirus vaccine.

Preventable stillbirths in India and Pakistan: a prospective, observational study.

OBJECTIVE: Stillbirths occur 10-20 times more frequently in low-income settings compared with high-income settings. We created a methodology to define the proportion of stillbirths that are potentially preventable in low-income settings and applied it to stillbirths in sites in India and Pakistan. DESIGN: Prospective observational study. SETTING: Three maternity hospitals in Davangere, India and a large public hospital in Karachi, Pakistan. POPULATION: All cases of stillbirth at ≥20 weeks of gestation occurring from July 2018 to February 2020 were screened for participation; 872 stillbirths were included in this analysis. METHODS: We prospectively defined the conditions and gestational ages that defined the stillbirth cases considered potentially preventable. Informed consent was sought from the parent(s) once the stillbirth was identified, either before or soon after delivery. All information available, including obstetric and medical history, clinical course, fetal heart sounds on admission, the presence of maceration as well as examination of the stillbirth after delivery, histology, and polymerase chain reaction for infectious pathogens of the placenta and various fetal tissues, was used to assess whether a stillbirth was potentially preventable. MAIN OUTCOME MEASURES: Whether a stillbirth was determined to be potentially preventable and the criteria for assignment to those categories. RESULTS: Of 984 enrolled, 872 stillbirths at ≥20 weeks of gestation met the inclusion criteria and were included; of these, 55.5% were deemed to be potentially preventable. Of the 649 stillbirths at ≥28 weeks of gestation and ≥1000 g birthweight, 73.5% were considered potentially preventable. The most common conditions associated with a potentially preventable stillbirth at ≥28 weeks of gestation and ≥1000 g birthweight were small for gestational age (SGA) (52.8%), maternal hypertension (50.2%), antepartum haemorrhage (31.4%) and death that occurred after hospital admission (15.7%). CONCLUSIONS: Most stillbirths in these sites were deemed preventable and were often associated with maternal hypertension, antepartum haemorrhage, SGA and intrapartum demise. TWEETABLE ABSTRACT: Most stillbirths are preventable by better care for women with hypertension, growth restriction and antepartum haemorrhage.

A 1-Year Study on Association between Peripherally Inserted Central Catheter Tip Position and Complications in Neonates.

AIMS: A peripherally inserted central catheter (PICC) is required in preterm neonates, especially those with low birth weight. However, PICC is associated with various complications resulting in increased morbidity and mortality. The objective of the study was to evaluate the association between PICC tip position and complications in neonates. MATERIALS AND METHODS: One hundred neonates were recruited in a 1-year hospital-based, longitudinal, observational study. Radiographs were obtained to confirm the position of the catheter tip as central or noncentral in relation to vertebral level (T9-L5). The variables studied included site of insertion, duration of stay of PICC, time of removal, reason for removal, and associated complications. These were compared between the groups using SPSS version 20. Fisher's exact test was used to find the associations. RESULTS: Most of the neonates were preterm (78%) and 81% were low birth weight. Catheter was placed in the right lower limb in most of the neonates (85%), and the catheter tip was central in position in 84% of neonates. The incidence of complications was observed in 29%. Noninfectious complications were common (26%) compared to infectious (3%). The most frequent PICC-induced complication was phlebitis (11%). Incidence of complications (P = 0.020), especially occlusion (P = 0.008), was significantly higher in neonates with noncentral catheter tip compared to the central tip. CONCLUSION: We observed a high incidence of PICC-induced complications in neonates, with phlebitis being most common. Further, the incidence of complications is influenced by noncentral tip position.

A Prospective, Population-Based Study of Trends in Operative Vaginal Delivery Compared to Cesarean Delivery Rates in Low- and Middle-Income Countries, 2010-2016.

OBJECTIVE: Few data are available on cesarean delivery and operative vaginal delivery trends in low- and middle-income countries. Our objective was to analyze a prospective population-based registry including eight sites in seven low- and middle-income countries to observe trends in operative vaginal delivery versus cesarean delivery rates over time, across sites. STUDY DESIGN: A prospective population-based study, including home and facility births among women enrolled from 2010 to 2016, was performed in communities in Argentina, Democratic Republic of Congo, Guatemala, India, Kenya, Pakistan, and Zambia. Women were enrolled during pregnancy and delivery outcome data were collected. RESULTS: We analyzed 354,287 women; 4,119 (1.2%) underwent an operative vaginal delivery and 45,032 (11.2%) delivered by cesarean. Across all sites with data for 7 years, rates of operative vaginal delivery decreased from 1.6 to 0.3%, while cesarean delivery increased from 6.4 to 14.4%. Similar trends were seen when individual country data were analyzed. Operative vaginal delivery rates decreased in both hospitals and clinics, except in the hospital setting at one of the Indian sites. CONCLUSION: In low- and middle-income countries, operative vaginal delivery is becoming less utilized while cesarean delivery is becoming an increasingly common mode of delivery.

A prospective cause of death classification system for maternal deaths in low and middle-income countries: results from the Global Network Maternal Newborn Health Registry.

OBJECTIVE: To describe the causes of maternal death in a population-based cohort in six low- and middle-income countries using a standardised, hierarchical, algorithmic cause of death (COD) methodology. DESIGN: A population-based, prospective observational study. SETTING: Seven sites in six low- to middle-income countries including the Democratic Republic of the Congo (DRC), Guatemala, India (two sites), Kenya, Pakistan and Zambia. POPULATION: All deaths among pregnant women resident in the study sites from 2014 to December 2016. METHODS: For women who died, we used a standardised questionnaire to collect clinical data regarding maternal conditions present during pregnancy and delivery. These data were analysed using a computer-based algorithm to assign cause of maternal death based on the International Classification of Disease-Maternal Mortality system (trauma, termination of pregnancy-related, eclampsia, haemorrhage, pregnancy-related infection and medical conditions). We also compared the COD results to healthcare-provider-assigned maternal COD. MAIN OUTCOME MEASURES: Assigned causes of maternal mortality. RESULTS: Among 158 205 women, there were 221 maternal deaths. The most common algorithm-assigned maternal COD were obstetric haemorrhage (38.6%), pregnancy-related infection (26.4%) and pre-eclampsia/eclampsia (18.2%). Agreement between algorithm-assigned COD and COD assigned by healthcare providers ranged from 75% for haemorrhage to 25% for medical causes coincident to pregnancy. CONCLUSIONS: The major maternal COD in the Global Network sites were haemorrhage, pregnancy-related infection and pre-eclampsia/eclampsia. This system could allow public health programmes in low- and middle-income countries to generate transparent and comparable data for maternal COD across time or regions. TWEETABLE ABSTRACT: An algorithmic system for determining maternal cause of death in low-resource settings is described.

Global Network for Women's and Children's Health Research: probable causes of stillbirth in low- and middle-income countries using a prospectively defined classification system.

OBJECTIVE: We sought to classify causes of stillbirth for six low-middle-income countries using a prospectively defined algorithm. DESIGN: Prospective, observational study. SETTING: Communities in India, Pakistan, Guatemala, Democratic Republic of Congo, Zambia and Kenya. POPULATION: Pregnant women residing in defined study regions. METHODS: Basic data regarding conditions present during pregnancy and delivery were collected. Using these data, a computer-based hierarchal algorithm assigned cause of stillbirth. Causes included birth trauma, congenital anomaly, infection, asphyxia, and preterm birth, based on existing cause of death classifications and included contributing maternal conditions. MAIN OUTCOME MEASURES: Primary cause of stillbirth. RESULTS: Of 109 911 women who were enrolled and delivered (99% of those screened in pregnancy), 2847 had a stillbirth (a rate of 27.2 per 1000 births). Asphyxia was the cause of 46.6% of the stillbirths, followed by infection (20.8%), congenital anomalies (8.4%) and prematurity (6.6%). Among those caused by asphyxia, 38% had prolonged or obstructed labour, 19% antepartum haemorrhage and 18% pre-eclampsia/eclampsia. About two-thirds (67.4%) of the stillbirths did not have signs of maceration. CONCLUSIONS: Our algorithm determined cause of stillbirth from basic data obtained from lay-health providers. The major cause of stillbirth was fetal asphyxia associated with prolonged or obstructed labour, pre-eclampsia and antepartum haemorrhage. In the African sites, infection also was an important contributor to stillbirth. Using this algorithm, we documented cause of stillbirth and its trends to inform public health programs, using consistency, transparency, and comparability across time or regions with minimal burden on the healthcare system. TWEETABLE ABSTRACT: Major causes of stillbirth are asphyxia, pre-eclampsia and haemorrhage. Infections are important in Africa.

A prospective population-based study of maternal, fetal, and neonatal outcomes in the setting of prolonged labor, obstructed labor and failure to progress in low- and middle-income countries.

BACKGROUND: This population-based study sought to quantify maternal, fetal, and neonatal morbidity and mortality in low- and middle-income countries associated with obstructed labor, prolonged labor and failure to progress (OL/PL/FTP). METHODS: A prospective, population-based observational study of pregnancy outcomes was performed at seven sites in Argentina, Guatemala, India (2 sites, Belgaum and Nagpur), Kenya, Pakistan and Zambia. Women were enrolled in pregnancy and delivery and 6-week follow-up obtained to evaluate rates of OL/PL/FTP and outcomes resulting from OL/PL/FTP, including: maternal and delivery characteristics, maternal and neonatal morbidity and mortality and stillbirth. RESULTS: Between 2010 and 2013, 266,723 of 267,270 records (99.8%) included data on OL/PL/FTP with an overall rate of 110.4/1000 deliveries that ranged from 41.6 in Zambia to 200.1 in Pakistan. OL/PL/FTP was more common in women aged <20, nulliparous women, more educated women, women with infants >3500g, and women with a BMI >25 (RR 1.4, 95% CI 1.3 - 1.5), with the suggestion of OL/PL/FTP being less common in preterm deliveries. Protective characteristics included parity of ≥3, having an infant <1500g, and having a BMI <18. Women with OL/PL/FTP were more likely to die within 42 days (RR 1.9, 95% CI 1.4 - 2.4), be infected (RR 1.8, 95% CI 1.5 - 2.2), and have hemorrhage antepartum (RR 2.8, 95% CI 2.1 - 3.7) or postpartum (RR 2.4, 95% CI 1.8 - 3.3). They were also more likely to have a stillbirth (RR 1.6, 95% CI 1.3 - 1.9), a neonatal demise at < 28 days (RR 1.9, 95% CI 1.6 - 2.1), or a neonatal infection (RR 1.2, 95% CI 1.1 - 1.3). As compared to operative vaginal delivery and cesarean section (CS), women experiencing OL/PL/FTP who gave birth vaginally were more likely to become infected, to have an infected neonate, to hemorrhage in the antepartum and postpartum period, and to die, have a stillbirth, or have a neonatal demise. Women with OL/PL/FTP were far more likely to deliver in a facility and be attended by a physician or other skilled provider than women without this diagnosis. CONCLUSIONS: Women with OL/PL/FTP in the communities studied were more likely to be primiparous, younger than age 20, overweight, and of higher education, with an infant with birthweight of >3500g. Women with this diagnosis were more likely to experience a maternal, fetal, or neonatal death, antepartum and postpartum hemorrhage, and maternal and neonatal infection. They were also more likely to deliver in a facility with a skilled provider. CS may decrease the risk of poor outcomes (as in the case of antepartum hemorrhage), but unassisted vaginal delivery exacerbates all of the maternal, fetal, and neonatal outcomes evaluated in the setting of OL/PL/FTP.

MRI abnormalities of the anterior temporal lobe: a new indicator of congenital cytomegalovirus infection.

Abnormalities of the anterior part of the temporal lobe (abnormal and swollen white matter, cysts, and focal enlargement of the anterior part of the inferior horn- either alone or more often in combination) suggest congenital cytomegalovirus (CMV) infection. This is not widely known. These can be seen in neonatal period and they continue to persist in later life.

Delayed presentation of false abdominal aortic aneurysm following umbilical artery catheterisation.

An eight-month-old male child presented with a nonpulsatile abdominal mass, which was detected during a routine follow-up examination. After ultrasound examination a tentative diagnosis of pseudoaneurysm of the abdominal aorta was made. An umbilical artery catheterisation had been performed for procuring arterial blood gases after birth for treatment of birth hypoxia. There was a history of fever subsequent to the umbilical artery catheterisation with positive blood and catheter tip cultures for coagulase-positive Staphylococci and Klebsiella pneumoniae. He had also suffered from infectious arthritis of the left hip joint one month after the catheterisation. CT scan with enhancement and angiography confirmed the diagnosis. He was treated successfully with excision of the aneurysm and direct repair of the aorta. A false abdominal artery aneurysm has been noted very rarely as a complication of umbilical artery catheterisation. Such an aneurysm most probably develops from infected thrombi which weaken the aortic wall. Diagnosis may be delayed as the child can remain asymptomatic. CT scan with contrast enhancement can give precise diagnosis. Angiography may be done preoperatively. The safest management is early surgery with direct repair.

Clinical spectrum and follow-up study of congenital hypothyroidism at District Hospital in India.

Twenty cases of clinically diagnosed congenital hypothyroidism during a 7-year period at a District Hospital in South India are analysed. A maximum of nine cases were diagnosed in the age group 1-5 years, only two before 3 months of age and five after 10 years of age. Two siblings of one family had the disease. Three children were associated with muscular hypertrophy, i.e. Kocher-Debre-Semelaigne Syndrome. Constipation and delayed milestones were the commonest symptoms (60 per cent). Classical facies (100 per cent), wide open anterior fontanella (65 per cent), coarse skin (60 per cent), and stunted growth (60 per cent) were the common physical findings. IQ was in between 30 and 40 in 60 per cent of cases. Only 50 per cent of them were followed up for a period of 1-5 years. Though physical growth was good on thyroxine IQ of above 80 was achieved in only three (30 per cent).
