RESUMO

INTRODUCTION: Reliable methods for identifying prematurity and low birth weight (LBW) are crucial to ending preventable deaths in newborns. This study explored healthcare providers' (HCPs) knowledge, practice, perceived barriers in assessing gestational age and birth weight and their referral methods for preterm and LBW infants. The study additionally assessed the potential of using a mobile app for the identification and referral decision of preterm and LBW. METHODS: This qualitative descriptive study was conducted in Thatta District, Sindh, Pakistan. Participants, including doctors, nurses, lady health visitors, and midwives, were purposefully selected from a district headquarter hospital, and private providers in the catchment area of Global Network's Maternal and Newborn Health Registry (MNHR). Interviews were conducted using an interview guide after obtaining written informed consent. Audio recordings of the interviews were transcribed and analyzed using NVIVO® software with an inductive approach. RESULTS: The HCPs had extensive knowledge about antenatal and postnatal methods for assessing gestational age. They expressed a preference for antenatal ultrasound due to the perceived accuracy, though accept practical barriers including workload, machine malfunctions, and cost. Postnatal assessment using the Ballard score was only undertaken sparingly due to insufficient training and subjectivity. All HCPs preferred electronic weighing scales for birth weight Barriers encountered included weighing scale calibration and battery issues. There was variation in the definition of prematurity and LBW, leading to delays in referral. Limited resources, inadequate education, and negative parent past experiences were barriers to referral. Foot length measurements were not currently being used. While mobile apps are felt to have potential, unreliable electricity supply and internet connectivity are barriers. CONCLUSION: The HCPs in this study were knowledgeable in terms of potential tools, but acknowledged the logistical and parental barriers to implementation.

RESUMO

Objective. To create a prediction model for preterm neonatal mortality. Methods. A secondary analysis was conducted using data from a prospective cohort study, the Project to Understand and Research Preterm Pregnancy Outcome South Asia. The Cox proportional hazard model was used and adjusted hazard ratios (AHR) with 95% confidence intervals (95% CI) were reported. Results. Overall, 3446 preterm neonates were included. The mean age of preterm neonates was 0.65 (1.25) hours and 52% were female. The preterm neonatal mortality rate was 23.3%. The maternal factors predicting preterm neonatal death was any antepartum hemorrhage, AHR 1.99 (1.60-2.47), while neonatal predictors were preterm who received positive pressure ventilation AHR 1.30 (1.08-1.57), temperature <35.5°C AHR 1.18 (1.00-1.39), and congenital malformations AHR 3.31 (2.64-4.16). Conclusion. This study identified key maternal and neonatal predictors of preterm neonatal mortality, emphasizing the need for targeted interventions and collaborative public health efforts to address disparities and regional variations.

RESUMO

OBJECTIVE: Because low-dose aspirin is now commonly prescribed in pregnancy, we sought to assess the association between early antenatal exposure and child neurodevelopment. METHODS: We performed a noninferiority, masked, neurodevelopmental follow-up study of children between age 33 and 39 months whose mothers had been randomized to daily low-dose aspirin (81 mg) or placebo between 6 0/7 and 13 6/7 weeks of gestation through 37 weeks. Neurodevelopment was assessed with the Bayley-III (Bayley Scales of Infant and Toddler Development, 3rd Edition) and the ASQ-3 (Ages and Stages Questionnaire, 3rd Edition). The primary outcome was the Bayley-III cognitive composite score with a difference within 4 points demonstrating noninferiority. RESULTS: A total of 640 children (329 in the low-dose aspirin group, 311 in the placebo group) were evaluated between September 2021 and June 2022. The Bayley-III cognitive composite score was noninferior between the two groups (-1, adjusted mean -0.8, 95% CI, -2.2 to 0.60). Significant differences were not seen in the language composite score (difference 0.7, 95% CI, -0.8 to 2.1) or the motor composite score (difference -0.6, 95% CI, -2.5 to 1.2). The proportion of children who had any component of the Bayley-III score lower than 70 did not differ between the two groups. Similarly, the communication, gross motor, fine motor, problem-solving, and personal-social components of the ASQ-3 did not differ between groups. Maternal characteristics, delivery outcomes, breastfeeding rates, breastfeeding duration, and home environment as measured by the Family Care Indicators were similar. CONCLUSION: Antenatal low-dose aspirin exposure was not associated with altered neurodevelopmental outcomes at age 3 years. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov , NCT04888377.

RESUMO

OBJECTIVE: Group B streptococcus (GBS) has been associated with adverse pregnancy outcomes, but few prospective studies have assessed its prevalence in low- and middle-income country settings. We sought to evaluate the prevalence of GBS by polymerase chain reaction (PCR) in internal organ tissues and placentas of deceased neonates and stillbirths. DESIGN: This was a prospective, observational study. SETTING: The study was conducted in hospitals in India and Pakistan. POPULATION: Pregnant women with stillbirths or preterm births were recruited at delivery, as was a group of women with term, live births, to serve as a control group. METHODS: A rectovaginal culture was collected from the women in Pakistan to assess GBS carriage. Using PCR, we evaluated GBS in various tissues of stillbirths and deceased neonates and their placentas, as well as the placentas of live-born preterm and term control infants. MAIN OUTCOME MEASURES: GBS identified by PCR in various tissues and the placentas; rate of stillbirths and 28-day neonatal deaths. RESULTS: The most obvious finding from this series of analyses from India and Pakistan was that no matter the country, the condition of the subject, the tissue studied or the methodology used, the prevalence of GBS was low, generally ranging between 3% and 6%. Among the risk factors evaluated, only GBS positivity in primigravidae was increased. CONCLUSIONS: GBS diagnosed by PCR was identified in <6% of internal organs of stillbirths and neonatal deaths, and their placentas, and control groups in South Asian sites. This is consistent with other reports from South Asia and is lower than the reported GBS rates from the USA, Europe and Africa.

RESUMO

The PURPOSe study was a prospective, observational study conducted in India and Pakistan to determine the cause of death for stillbirths and preterm neonatal deaths, using clinical data together with minimally invasive tissue sampling (MITS) and the histologic and polymerase chain reaction (PCR) evaluation of fetal/neonatal tissues and the placenta. After evaluating all available data, an independent panel chose a maternal, a placental and a fetal/neonatal cause of death. Here, we summarise the major results. Among the most important findings were that most stillbirths were caused by fetal asphyxia, often preceded by placental malperfusion, and clinically associated with pre-eclampsia, placental abruption and a small-for-gestational-age fetus. The preterm neonatal deaths were primarily caused by birth asphyxia, followed by various infections. An important finding was that many of the preterm neonatal deaths were caused by a nosocomial infection acquired after neonatal intensive care (NICU) admission; the most common organisms were Acinetobacter baumannii, followed by Klebsiella pneumoniae, Escherichia coli/Shigella and Haemophilus influenzae. Group B streptococcus was less commonly present in the placentas or internal organs of the neonatal deaths.

RESUMO

OBJECTIVE: To evaluate the usefulness of data to determine cause of stillbirth in India and Pakistan. DESIGN: Prospective, observational study. SETTINGS: Study hospitals in India and Pakistan. POPULATION: 200 fetal deaths with placental evaluation and minimally invasive tissue sampling (MITS) of internal organs and polymerase chain reaction (PCR) test for 75 pathogens. MAIN OUTCOME MEASURES: Data defined as useful to determine stillbirth causes. RESULTS: Placental pathology was the most useful to determine cause of stillbirth. Comparing placental and fetal weight with standard weights was useful in 44.5% and 48.5%, respectively. Lung histology was useful in 42.5%. Most of the other findings of internal organ histology were only occasionally useful. Signs of abruption, by maternal history or placental evaluation, were always deemed useful. Placenta, brain and cord blood PCR were also useful, but less often than histology. CONCLUSION: Based on this analysis, maternal clinical history, placental histology and fetal examination were most informative. Comparing the placental and fetal weights with recognised standards was useful in nearly half the cases. Fetal tissue histology and PCR were also informative. Of all the potential tests of MITS-obtained specimens, we would first recommend histological evaluation of the lungs, and using a multiplex PCR platform would determine pathogens in blood and brain/CSF. We recognise that this approach will not identify some causes, including some genetic and internal organ anomalies, but will confirm most common causes of stillbirth and most of the preventable causes of stillbirth in low- and middle-income countries.

RESUMO

OBJECTIVE: To explore potential reasons for differences in preterm neonatal mortality in neonatal intensive care units (NICUs) in India and Pakistan. DESIGN: A prospective observational study, the Project to Understand and Research Stillbirth and Preterms in Southeast Asia (PURPOSe) was conducted July 2018 to February 2020. SETTING: Three hospitals in Davangere, India, and a large public hospital in Karachi, Pakistan. POPULATION: Of a total of 3,202 preterm infants enrolled, 1,512 were admitted to a study NICU. METHODS: We collected data for neonates, including length of stay, diagnoses, and diagnostic tests. MAIN OUTCOME MEASURES: Neonatal mortality, tests performed, diagnoses ascertained. RESULTS: For infants of equivalent weights and gestational ages, neonatal mortality in Pakistan was twice that in the Indian NICU. The mean newborn length of stay in Pakistan was 2 days compared with 10 days for India. Fewer diagnostics and other investigations were used to determine neonatal condition or guide treatment in the Pakistani NICU. Because of limited information from testing in Pakistan concerning clinical respiratory distress, respiratory distress syndrome appeared to be over-diagnosed, whereas other conditions including pneumonia, sepsis, necrotising entercolitis and intraventricular haemorrhage were rarely diagnosed. CONCLUSION: In the Pakistani site, the limited resources available to the NICU appeared related to a shorter length of stay and decreased diagnostic testing, likely explaining the higher mortality. With improved care, reduction in mortality among preterm neonates should be achievable.

RESUMO

OBJECTIVE: To evaluate perinatal outcomes in preterm multiple compared with singleton pregnancies in India and Pakistan. DESIGN: Prospective, observational study. SETTINGS: Study hospitals in India and Pakistan. POPULATION: We evaluated 3897 preterm pregnancies. These mothers gave birth to 3615 (92.8%) singleton infants, 267 (6.8%) sets of twins, 14 (0.4%) sets of triplets and one set of quadruplets. MAIN OUTCOME MEASURES: Neonatal mortality, stillbirth, cause of death. RESULTS: Of the singleton infants, 691 (19.1%) were stillborn and 2924 (80.9%) live born. Of the 534 infants from twin pregnancies, 41 (7.7%) were stillborn and 493 (92.3%) were live born. Of the 267 sets of twins, in 14 cases (5.2%) both were stillborn, in 13 cases (4.8%) one was stillborn and one live born, and in 240 cases (90.0%) both were live born. In both preterm twins and preterm singletons, the three most common causes of death were intrauterine hypoxia, infections acquired prior to birth and infections acquired at or after birth. The preterm twins appeared less likely to have died from intrauterine hypoxia but more likely to have died from infections acquired at or after birth. Respiratory distress syndrome (RDS) was less likely considered by the panel to be the primary cause of death in either the twins (9.6%) or singletons (9.7%). Congenital anomalies were also not often judged to be the cause of death in either the preterm twins 2 (2.4%) or singletons 27 (5.3%). CONCLUSION: In the PURPOSe study, neonatal mortality rates in preterm twins compared with singletons when evaluated by sex, GA, birthweight and SGA, were generally similar to rates of preterm singleton neonatal mortality in those groups. Thus, the higher rate of mortality in live-born twin infants is related to the fact that these infants were more likely to be born earlier rather than to any inherent characteristics of the babies themselves.

RESUMO

OBJECTIVE: To examine internal organ tissues and placentas of stillbirths for various pathogens. DESIGN: Prospective, observational study. SETTINGS: Three study hospitals in India and a large maternity hospital in Pakistan. POPULATION: Stillborn infants delivered in a study hospital. METHODS: A prospective observational study. MAIN OUTCOME MEASURES: Organisms identified by pathogen polymerase chain reaction (PCR) in internal organs and placental tissues of stillbirths. RESULTS: Of 2437 stillbirth internal tissues, 8.3% (95% CI 7.2-9.4) were positive. Organisms were most commonly detected in brain (12.3%), cerebrospinal fluid (CSF) (9.5%) and whole blood (8.4%). Ureaplasma urealyticum/parvum was the organism most frequently detected in at least one internal organ (6.4% of stillbirths and 2% of all tissues). Escherichia coli/Shigella was the next most common (4.1% one or more internal organ tissue sample and 1.3% of tissue samples), followed by Staphylococcus aureus in at least one internal organ tissue (1.9% and 0.9% of all tissues). None of the other organisms was found in more than 1.4% of the tissue samples in stillbirths or more than 0.6% of the internal tissues examined. In the placenta tissue, membrane or cord blood combined, 42.8% (95% CI 40.2-45.3) had at least one organism identified, with U. urealyticum/parvum representing the most commonly identified (27.8%). CONCLUSIONS: In about 8% of stillbirths, there was evidence of a pathogen in an internal organ. Ureaplasma urealyticum/parvum was the most common organism found in the placenta and in the internal tissues, especially in the fetal brain.

RESUMO

The objective of the study was to determine the diagnostic accuracy of Mentzer Index in children with hypochromic microcytic anemia by taking serum ferritin levels as a gold standard. This cross-sectional study was conducted in the Department of Pediatric Medicine, Liaquat National Hospital Karachi, from 1st January to 30th June 2022. Children age 1 to 5 years and both genders were included in this study. Children who have had a history of blood transfusion in the past 3 months or Thalassemia or blood disorders, chronic liver disease or kidney diseases, and children with malignancy and congenital abnormalities were excluded. Eligible children were enrolled after taking written informed consent. Complete blood count (CBC) and serum ferritin were sent to the laboratory. Sensitivity, specificity, diagnostic accuracy, and likelihood ratio were calculated taking serum ferritin levels as a gold standard. A total of 347 subjects were enrolled. The median age was 26 (IQR-18) months and 42.9% were males. The most common symptom was fatigue 40.9%. The sensitivity of the Mentzer index was 80.7% while the specificity was 77.7%. Similarly, the positive predictive value (PPV) was 56.8% while the negative predictive value (NPV) was 91.6%. Finally, the accuracy of the Mentzer index in determining iron deficiency anemia was 78.4%. Diagnostic accuracy was 78.4% and the likelihood ratio was 3.6. Mentzer index is a valuable tool in the early detection of IDA in children. It has got high sensitivity, specificity diagnostic accuracy, and likelihood ratio.

RESUMO

BACKGROUND: We identified pathogens found in internal organs and placentas of deceased preterm infants cared for in hospitals in India and Pakistan. METHODS: Prospective, observational study conducted in delivery units and neonatal intensive care units. Tissue samples from deceased neonates obtained by minimally invasive tissue sampling and placentas were examined for 73 different pathogens using multiplex polymerase chain reaction (PCR). RESULTS: Tissue for pathogen PCR was obtained from liver, lung, brain, blood, cerebrospinal fluid, and placentas from 377 deceased preterm infants. Between 17.6% and 34.1% of each type of tissue had at least 1 organism identified. Organism detection was highest in blood (34.1%), followed by lung (31.1%), liver (23.3%), cerebrospinal fluid (22.3%), and brain (17.6%). A total of 49.7% of the deceased infants had at least 1 organism. Acinetobacter baumannii was in 28.4% of the neonates compared with 14.6% for Klebsiella pneumoniae, 11.9% for Escherichia coli/Shigella, and 11.1% for Haemophilus influenzae. Group B streptococcus was identified in only 1.3% of the neonatal deaths. A. baumannii was rarely found in the placenta and was found more commonly in the internal organs of neonates who died later in the neonatal period. The most common organism found in placentas was Ureaplasma urealyticum in 34% of the samples, with no other organism found in >4% of samples. CONCLUSIONS: In organ samples from deceased infants in India and Pakistan, evaluated with multiplex pathogen PCR, A. baumannii was the most commonly identified organism. Group B streptococcus was rarely found. A. baumannii was rarely found in the placentas of these deceased neonates.

RESUMO

BACKGROUND: Preterm birth remains the major cause of neonatal death worldwide. South Asia contributes disproportionately to deaths among preterm births worldwide, yet few population-based studies have assessed the underlying causes of deaths. Novel evaluations, including histological and bacteriological assessments of placental and fetal tissues, facilitate more precise determination of the underlying causes of preterm deaths. We sought to assess underlying and contributing causes of preterm neonatal deaths in India and Pakistan. METHODS: The project to understand and research preterm pregnancy outcomes and stillbirths in South Asia (PURPOSe) was a prospective cohort study done in three hospitals in Davangere, India, and two hospitals in Karachi, Pakistan. All pregnant females older than 14 years were screened at the time of presentation for delivery, and those with an expected or known preterm birth, defined as less than 37 weeks of gestation, were enrolled. Liveborn neonates with a weight of 1000 g or more who died by 28 days after birth were included in analyses. Placentas were collected and histologically evaluated. In addition, among all neonatal deaths, with consent, minimally invasive tissue sampling was performed for histological analyses. PCR testing was performed to assess microbial pathogens in the placental, blood, and fetal tissues collected. An independent panel reviewed available data, including clinical description of the case and all clinical maternal, fetal, and placental findings, and results of PCR bacteriological investigation and minimally invasive tissue sampling histology, from all eligible preterm neonates to determine the primary and contributing maternal, placental, and neonatal causes of death. FINDINGS: Between July 1, 2018, and March 26, 2020, of the 3470 preterm neonates enrolled, 804 (23%) died by 28 days after birth, and, of those, 615 were eligible and had their cases reviewed by the panel. Primary maternal causes of neonatal death were hypertensive disease (204 [33%] of 615 cases), followed by maternal complication of pregnancy (76 [12%]) and preterm labour (76 [11%]), whereas the primary placental causes were maternal and fetal vascular malperfusion (172 [28%] of 615) and chorioamnionitis, funisitis, or both (149 [26%]). The primary neonatal cause of death was intrauterine hypoxia (212 [34%] of 615) followed by congenital infections (126 [20%]), neonatal infections (122 [20%]), and respiratory distress syndrome (126 [20%]). INTERPRETATION: In south Asia, intrauterine hypoxia and congenital infections were the major causes of neonatal death among preterm babies. Maternal hypertensive disorders and placental disorders, especially maternal and fetal vascular malperfusion and placental abruption, substantially contributed to these deaths.

RESUMO

BACKGROUND: South Asia contributes more than a third of all global stillbirths, yet the causes remain largely unstudied in this region. New investigations, including novel assessments of placental and fetal tissues, facilitate more precise determination of the underlying causes of stillbirth. We sought to assess underlying and contributing causes of stillbirth from settings in India and Pakistan. METHODS: In this prospective cohort study (PURPOSe), we report the cause of death in stillbirths in hospitals in central India and south Pakistan (Davangere, India [three public and private hospitals] and Karachi, Pakistan [one public maternity and one children's hospital]). Women aged 15 years or older and with a known stillbirth (defined as a pregnancy at 20 or more weeks of gestation with the in-utero death of a fetus) weighing 1000 g or more were included in the study. Maternal clinical factors, placental evaluation, fetal tissue evaluation (from minimally invasive tissue sampling), and PCR for microbial pathogens were used to identify the causes of death. An expert panel reviewed available data for all stillbirths to identify the primary and contributing maternal, placental, and fetal causes of stillbirth. FINDINGS: Between Sept 1, 2018, and Feb 12, 2020, 981 stillborns were included and, of those, 611 were reviewed by the expert panel. The primary maternal causes of stillbirth were hypertensive disease in 221 (36%) of 611 stillbirths, followed by severe anaemia in 66 (11%) stillbirths. The primary placental causes were maternal and fetal vascular malperfusion, in 289 (47%) stillbirths. The primary fetal cause of stillbirth was intrauterine hypoxia, in 437 (72%) stillbirths. We assessed the overlap of main causes and 116 (19%) stillbirths had intrauterine hypoxia, placental malperfusion, and eclampsia or pre-eclampsia indicated as primary causes of death. Infection (including of the placenta, its membranes, and in the fetus) and congenital anomalies also were causative of stillbirth. INTERPRETATION: In south Asia, fetal asphyxia is the major cause of stillbirth. Several placental lesions, especially those associated with maternal and fetal vascular malperfusion and placental abruption, have an important role in asphyxia and fetal death. Maternal hypertension, and especially pre-eclampsia, is often the primary maternal condition associated with this pathway. FUNDING: Bill & Melinda Gates Foundation.

RESUMO

OBJECTIVE: To assess respiratory distress syndrome (RDS) compared with birth asphyxia as the cause of death in preterm newborns, assigned by the neonatal intensive care unit (NICU) physician at the time of death and assigned by a panel with complete obstetric history, placental evaluation, tissue histology and microbiology. DESIGN: Prospective, observational study. SETTINGS: Study NICUs in India and Pakistan. POPULATION: Preterm infants delivered in study facility. METHODS: A total of 410 preterm infants who died in the NICU with cause of death ascertained by the NICU physicians and independently by expert panels. We compared the percentage of cases assigned RDS versus birth asphyxia as cause of death by the physician and the panel. MAIN OUTCOME MEASURES: RDS and birth asphyxia. RESULTS: Of 410 preterm neonatal deaths, the discharging NICU physicians found RDS as a cause of death among 83.2% of the cases, compared with the panel finding RDS in only 51.0%. In the same neonatal deaths, the NICU physicians found birth asphyxia as a cause of death in 14.9% of the deaths, whereas the panels found birth asphyxia in 57.6% of the deaths. The difference was greater in Pakistan were the physicians attributed 89.7% of the deaths to RDS and less than 1% to birth asphyxia whereas the panel attributed 35.6% of the deaths to RDS and 62.7% to birth asphyxia. CONCLUSIONS: NICU physicians who reported cause of death in deceased preterm infants less often attributed the death to birth asphyxia, and instead more often chose RDS, whereas expert panels with more extensive data attributed a greater proportion of deaths to birth asphyxia than did the physicians.

RESUMO

Introduction: Maternal infections likely are an important cause of stillbirths, especially in sub-Saharan Africa and south Asia, where the burden is highest. Due to the lack of routine testing for infection, which can be complex and often expensive, the prevalence of infection during pregnancy and the association of many infections with stillbirth are not well-documented, especially in low-resource countries.Methods: Following an extensive literature review of infection and stillbirth initially published in 2010, we conducted a review of literature in the last 10 years to identify infections associated with stillbirth, focused on those in low-resource settings.Results: During the last 10 years, over 40 bacterial, viral and other pathogens have been associated with stillbirth. Newly emerging viral infections such as Denge as well as several well-established, but not yet eliminated infections such as rubella have been associated with stillbirth. Two of the maternal infections most strongly associated with stillbirth, each with about a 2-fold risk, are malaria and syphilis but others have been associated with risk in a range of studies. With a lack of routine antenatal screening, many pathogens are identified as associated with stillbirth only through case reports. Infection remains an important, yet understudied, cause of stillbirth.Conclusion: Research studies to determine definitive associations between various infections and stillbirth are important to better understand the role of infections and strategies to reduce infection-related stillbirth.Summary This review explores the association between infections and stillbirths focusing on low-income country studies published in the last 10 years. Much information about these relationships comes from case reports. Research resulting in a better understanding of the causes and strategies to reduce infection-related stillbirth is necessary.

BACKGROUND: Minimally invasive tissue sampling (MITS) is a noninvasive technique used to determine the cause of deaths. Very little is known about the factors that affect MITS acceptance or refusal. We present findings from a prospective study conducted in Southeast Asia on the reasons for accepting or refusing MITS. METHODS: This substudy was conducted in India and Pakistan to determine the acceptability of MITS in women who had a stillbirth or preterm live birth who later died. A formal questionnaire was used to gather observations during the consent for MITS, such as reasons for acceptance or refusal of MITS, as well as which family members were involved in the decision process. RESULTS: In Pakistan, the MITS acceptability forms were completed for 470 of 477 women (98.5%) with an eligible stillbirth for this substudy, and 334 of 337 (99.1%) with an eligible preterm neonatal death. In India, MITS acceptability forms were completed in 219 of 305 women (71.8%) with an eligible stillbirth and 260 of 264 (98.4%) with an eligible preterm neonatal death. In India, the most common reasons for MITS refusal for both stillbirths and preterm neonatal deaths were cultural concerns, while in Pakistan, the most common reason for MITS refusal was a potential delay in the funeral. The primary reason for accepting MITS was that the parents wanted to understand the cause of death. At both sites, fathers, mothers, and relatives, often in consultation, choose whether or not to accept MITS to determine the cause of death in stillbirths and preterm neonatal deaths. CONCLUSIONS: MITS was more commonly accepted in India than in Pakistan. Cultural concerns in India and funeral delays in Pakistan were common reasons for refusal. Parents from both sites were curious to know the cause of stillbirths and preterm neonatal deaths. The father, mother, and relatives were key decision makers for consenting to or declining MITS.

RESUMO

BACKGROUND: Complete diagnostic autopsy (CDA) is considered to be the gold-standard procedure that aids in determination of cause of death in stillbirths and neonatal deaths. However, CDA is not routinely practiced in South Asian countries due to religious beliefs, lack of expertise, and lack of resources. Minimally invasive tissue sampling (MITS) has been recommended as a less mutilating and less expensive alternative to CDA for obtaining tissues for analysis. The present study aims to evaluate the yield of lung tissue and histological findings using MITS as part of a cause of death analysis for stillborns and preterm neonatal deaths. METHODS: Data were collected during an observational multicenter prospective study called the Project to Understand and Research Preterm birth and Stillbirth (PURPOSe) conducted in India and Pakistan. After obtaining written informed consent from parents, the eligible stillbirths and neonatal deaths were subjected to MITS using a standard protocol. The tissues were obtained from both lungs for histological and microbiological analysis. RESULTS: At both sites, a total of 453 stillbirths and 352 neonatal deaths underwent MITS. For stillbirths and neonatal deaths, the yield of lung tissue using MITS was high (92%). Intrauterine fetal distress and respiratory distress syndrome were the leading lung pathologies reported in stillbirths and neonatal deaths, respectively. CONCLUSIONS: MITS appears to be a reasonable alternative to CDA in obtaining and evaluating lung tissue to inform accurate cause of death analysis in stillbirth and preterm deaths.

RESUMO

BACKGROUND: In dyspeptic patients with Helicobacter pylori contributes to non-alcoholic fatty liver disease. However, little evidence available from Pakistan. OBJECTIVE: The study aims to determine the frequency and risk factors of non-alcoholic fatty liver disease in dyspeptic patients with Helicobacter pylori. METHODS: This cross-sectional study was conducted between 22 November 2016 and 30 June 2018. Adults of age between 18 and 90 years who attended the out-patient department due to abdominal discomfort, pain, fullness, and bloating who underwent upper gastrointestinal tract endoscopy were enrolled after taking informed consent. Patients with celiac disease, inflammatory bowel disease, taking alcohol, pregnant women and lactating mothers, known cases of hepatitis B and C, and history of recent antibiotic use were excluded. Data on age, gender, smoking, alcohol use, dyslipidemia, hypertension, type 2 diabetes mellitus, and ischemic heart disease were collected. Non-alcoholic fatty liver disease was diagnosed through ultrasonography. Helicobacter pylori infection was detected using a carbon urea breath test. RESULTS: A total of 698 patients were screened for eligibility, and 399 (57.2%) had Helicobacter pylori infection and were enrolled in the study after consent. The median age was 50.1 (interquartile range = 14.5) years and 209 (52.4%) were males. Frequency of non-alcoholic fatty liver disease in patients with Helicobacter pylori dyspeptic patients was 153 (38.3%). Factors associated with non-alcoholic fatty liver disease in the presence of Helicobacter pylori were dyslipidemia 7.38 (95% confidence interval = 2.4-22.71), type 2 diabetes mellitus 5.96 (95% confidence interval = 1.86-19.07), hypertension 3.0 (95% confidence interval = 1.21-7.45), and moderate gastritis 2.81 (95% confidence interval = 1.2-6.59). CONCLUSION: The frequency of non-alcoholic fatty liver disease in Helicobacter Pylori dyspeptic patients was 38.3%. Male gender, dyslipidemia, hypertension, ischemic heart disease, and moderate gastritis were associated with non-alcoholic fatty liver disease.
