Causes of stillbirths and neonatal deaths in Dhanusha district, Nepal: a verbal autopsy study.

BACKGROUND: Perinatal (stillbirths and first week neonatal deaths) and neonatal (deaths in the first 4 weeks) mortality rates remain high in developing countries like Nepal. As most births and deaths occur in the community, an option to ascertain causes of death is to conduct verbal autopsy. OBJECTIVE: The objective of this study was to classify and review the causes of stillbirths and neonatal deaths in Dhanusha district, Nepal. MATERIALS AND METHODS: Births and neonatal deaths were identified prospectively in 60 village development committees of Dhanusha district. Families were interviewed at six weeks after delivery, using a structured questionnaire. Cause of death was assigned independently by two pediatricians according to a predefined algorithm; disagreement was resolved in discussion with a consultant neonatologist. RESULTS: There were 25,982 deliveries in the 2 years from September 2006 to August 2008. Verbal autopsies were available for 601/813 stillbirths and 671/954 neonatal deaths. The perinatal mortality rate was 60 per 1000 births and the neonatal mortality rate 38 per 1000 live births. 84% of stillbirths were fresh and obstetric complications were the leading cause (67%). The three leading causes of neonatal death were birth asphyxia (37%), severe infection (30%) and prematurity or low birth weight (15%). Most infants were delivered at home (65%), 28% by relatives. Half of women received an injection (presumably an oxytocic) during home delivery to augment labour. Description of symptoms commensurate with birth asphyxia was commoner in the group of infants who died (41%) than in the surviving group (14%). CONCLUSION: The current high rates of stillbirth and neonatal death in Dhanusha suggest that the quality of care provided during pregnancy and delivery remains sub-optimal. The high rates of stillbirth and asphyxial mortality imply that, while efforts to improve hygiene need to continue, intrapartum care is a priority. A second area for consideration is the need to reduce the uncontrolled use of oxytocic for augmentation of labour.

Development and evaluation of a real-time PCR assay for detection of Pneumocystis jirovecii DNA in bronchoalveolar lavage fluid of HIV-infected patients.

BACKGROUND: Pneumocystis pneumonia (PCP) is conventionally diagnosed by identifying Pneumocystis jirovecii in lower respiratory tract samples using cytochemical stains. Molecular diagnosis of PCP is potentially more sensitive. METHODS: A study was undertaken to use an extensively optimised real-time polymerase chain reaction (PCR) using primers designed to hybridise with the P. jirovecii heat shock protein 70 (HSP70) gene to quantify P. jirovecii DNA in bronchoalveolar lavage (BAL) fluid from HIV-infected patients with and without PCP, and to compare this assay with conventional PCR targeting the P. jirovecii mitochondrial large subunit rRNA gene sequence (mt LSU rRNA). RESULTS: Sixty-one patients had 62 episodes of PCP (defined by detection of P. jirovecii in BAL fluid by cytochemical stains and typical clinical presentation). Quantifiable HSP70 DNA was detected in 61/62 (range approximately 13-18,608 copies/reaction; median approximately 332) and was detectable but below the limit of quantification (approximately 5 copies/reaction) in 1/62. Seventy-one other patients had 74 episodes with alternative diagnoses. Quantifiable HSP70 DNA was detectable in 6/74 (8%) episodes (range approximately 6-590 copies/reaction; median approximately 14) and detectable but below the limit of quantification in 34/74 (46%). Receiver-operator curve analysis (cut-off >10 copies/reaction) showed a clinical sensitivity of 98% (95% 91% to 100%) and specificity of 96% (95% CI 87% to 99%) for diagnosis of PCP. By contrast, clinical sensitivity of mt LSU rRNA PCR was 97% (95% CI 89% to 99%) and specificity was 68% (95% CI 56% to 78%). CONCLUSION: The HSP70 real-time PCR assay detects P. jirovecii DNA in BAL fluid and may have a diagnostic application. Quantification of P. jirovecii DNA by real-time PCR may also discriminate between colonisation with P. jirovecii and infection.

Prevalence of childhood and adolescent disabilities in rural Nepal.

The study aimed to determine the number of children and young people reported as having a disability by family members, and to classify impairments leading to disability. A Cross-sectional census was conducted of all households in 24 rural geopolitical units of Makwanpur district, Nepal. Heads of household were asked about family members under the age of 20 with disability. Such members were resident in 733 of 28,376 households, a household prevalence of 2.58%. 829 people under the age of 20 were reported as having a disability, a population prevalence of 0.95%. The commonest functional impairments reported were motor and the commonest anatomical impairments involved the limbs. More males with disability were identified than females.

Strengthening health care systems to improve infant health in rural Nepal.

PIP: The functioning of the government primary health care system as it affects infant health in the Baglung District of Nepal, is discussed. the Baglung District is a remote rural area of 232,000 population in the western Himalayan foothills, entirely based on subsistence farming, and without drivable roads. The government has a 15-bed hospital in the district capital, 11 health posts and 80 village-based community workers (VHWs). The Save the Children Fund also has a Maternal-Child Health Clinic with an expatriot doctor and 35 staff, funded by US $88,000 in 1984-5, and caring for about 10% of the district. District health administration could be improved by setting up communication links between the district capital, health posts and VHWs. The SCF funded a newsletter publicizing immunization and family planning campaigns, which were previously unannounced. The government has also tried to decentralize the control of staffing, pay, and health campaign scheduling from the national to the district level since 1985, with mixed success. Since the hospital runs out of drugs and supplies, and the health posts lack these as well as diagnostic equipment, water and sanitation, the public usually resorts to traditional healers. It is suggested that staff rotations be made during monsoons when people cannot travel, and that supplies be upgraded during the pre-monsoon when food is limited and morbidity is higher, VHWs are usually young men with little training, supplies or respect from the community. It would be best to strengthen health posts initially, then train VHWs by associating them with the health posts. Other suggestions are to gain the respect of the traditional healers for referrals, and to emphasize cost-effective ways to improve female education and literacy.^ieng

Perinatal health in developing countries.

PIP: In developing countries, child mortality declined during the 1980s, but neonatal mortality did not improve. Ministries of Health do not consider reduction of early neonatal mortality to be a priority. Underreporting of perinatal deaths is common (e.g., at least 40% of perinatal deaths). Researchers sometimes categorize perinatal deaths as other causes of infant mortality. Many people believe too technological or costly interventions are needed to reduce perinatal mortality, but simple, low-cost principles of newborn care do exist: keep the newborn warm, feed often, avoid infection, and keep the newborn close to the mother. A study in Zimbabwe shows that asphyxia, a preventable condition, occurred in 76% of cases. Prenatal care; education; improved treatment of syphilis, hypertension, diabetes, and amniotic fluid infection; closer monitoring of the fetal condition during labor; and proper management of abnormal labor would reduce perinatal deaths. Premature infants are at greater risk of death than are intrauterine growth retarded infants. Research is needed to learn more about the epidemiology, causes,, and sequelae of asphyxia as well as the most cost-effective interventions. 38% of newborns at a hospital in Kathmandu had mild or moderate hypoglycemia, 44% of whom experienced at least 3 hypoglycemic episodes in the first 2 days. Known hypoglycemic risk factors are low birth weight and hypothermia. Possible hypoglycemic risk factors are prelactal feeds and a delay in beginning breast feeding. Effective perinatal health care in developing countries requires a tired system of referral and a motivated community health worker trained to manage safe delivery and newborn care. Unfriendly staff and user charges are obstacles to primary perinatal health care, however. UNICEF's Baby Friendly Hospital initiative aims to stop distribution of free infant formula in maternity wards and to improve perinatal care.^ieng

Raised levels of agalactosyl IgG in childhood tuberculosis.

Raised levels of agalactosyl immunoglobulin G (IgG) have been found in adults with tuberculosis, Crohn's disease and rheumatoid arthritis, and recent evidence, both circumstantial and experimental, suggests that it has distinct functional properties that play a role in pathogenesis. Since tuberculosis in infants is strikingly different from the disease seen in adults, but switches to the adult form at adrenarche or puberty, we documented the association of agalactosyl IgG with tuberculosis in childhood between the ages of 0 and 16 years. Sera were collected from 99 children diagnosed as cases of tuberculosis in Istanbul, Turkey, and compared with levels in non-tuberculous controls. The percentage of agalactosyl IgG was significantly raised in children with tuberculosis overall (P < 0.001, Mann-Whitney U test) and in all age groups except for children over 12 years old, whose numbers were too small to be meaningful. Therefore the differences between adult and childhood tuberculosis are not due to a difference in the tendency for agalactosyl IgG to be produced at different ages. The percentage of agalactosyl IgG may be useful for monitoring the progress of individual complicated cases.

Does antibody to mycobacterial antigens, including lipoarabinomannan, limit dissemination in childhood tuberculosis?

Serum immunoglobulin (Ig) G responses to a variety of mycobacterial antigens were measured in children from the UK, in children with tuberculosis from Hyderabad, India and Dhaka, Bangladesh, classified according to whether the disease was disseminated or localized, and in non-tuberculous controls. Anti-lipoarabinomannan (LAM) IgG responses in UK children showed a marked trough between 6 months and 3 years coincident with the reported peak incidence of disseminated tuberculosis. Geometric mean IgG responses to sonicates of slow-growing mycobacteria (rich in LAM) in 36 children with disseminated tuberculosis were markedly lower than in 99 children with localized tuberculous lesions (for Mycobacterium scrofulaceum P < 0.01, for M. tuberculosis P < 0.01, and for M. vaccae P < 0.01). Responses to purified LAM were also lower in the disseminated tuberculosis group (P < 0.05) but there was no difference between the groups in their response to mycobacterial 65 kDa protein. Multiple regression analysis showed that the reduced response to sonicated mycobacterial antigens and to LAM in children with disseminated disease was independent of age, nutritional status, skin test reactivity, duration of previous symptoms, and city of origin. There was no evidence for sequestration of antibody to immune complexes. These findings are compatible with the hypothesis that children with low levels of antibody to sonicated mycobacterial antigen and to LAM, or those who cannot mount an antibody response, are predisposed to dissemination. A role for antibody in preventing disseminated forms of tuberculosis in childhood has implications for the development of improved vaccines and for the optimum timing of vaccination with bacille Calmette-Guérin.

Efficacy of outreach nutrition rehabilitation centres in reducing mortality and improving nutritional outcome of severely malnourished children in Guinea Bissau.

OBJECTIVE: There is still controversy about the efficacy and cost-effectiveness of outreach nutrition rehabilitation centres (NRCs) for severely malnourished children. We wanted to compare the mortality rates and nutritional status of severely malnourished children admitted to rural NRCs in Gabu region, Guinea Bissau, with other severely malnourished children who were not rehabilitated and stayed in their villages. DESIGN: Retrospective cohort study over a 3-year period. Mortality rates and nutritional outcome compared for children who were admitted to rural NRCs and those who were not rehabilitated. Selection for admission to the NRCs was based on availability of places only. SETTING: 19 health areas of the Gabu region, Guinea Bissau, West Africa. SUBJECTS: 1038 severely malnourished children (< 60% weight-for-age using NCHS standards) aged 6 to 47 months. 354 were rehabilitated in NRCs and 684 received no rehabilitation. RESULTS: Up to 36 months follow-up the relative risk of death in the rehabilitated group was 0.75 [95% confidence interval (c.i.) = 0.57-0.99], equivalent to a 25% reduction in mortality. The difference in mortality between the two groups was much higher during the first 3 months [P < 0.02, relative risk = 0.59 (95% c.i. = 0.39-0.91)]. Rehabilitated children had a higher mean weight gain in the first 3 months (1.63 compared to 0.56 weight-for-age standard deviation score, P < 0.001), and weight gain differences lasted up to 18 months (P < 0.01). CONCLUSIONS: Low-cost, outreach NRCs are effective both in the short term and in the mid-term to improve the nutritional situation and reduce the mortality of severely malnourished children.

PIP: Whether or not to provide nutrition rehabilitation for children with protein-energy malnutrition remains controversial. Hospital-based rehabilitation has been criticized as a waste of time and money due to the high levels of case fatality during treatment, after discharge, and among children who abscond. Nutrition rehabilitation centers (NRCs) were strongly recommended during the 1970s as an alternative to hospital treatment. International agencies have not, however, generally promoted NRCs as an integral part of primary health care. The authors measured the efficacy of rural NRCs in nineteen health areas in Gabu region, Guinea-Bissau, in reducing the mortality rates and improving the nutritional outcomes of severely malnourished children. The mortality rates and nutritional status of severely malnourished children admitted to the rural NRCs were compared with data on other severely malnourished children who were not rehabilitated and remained in their villages. 1038 children aged 6-47 months were involved in the study; 354 were rehabilitated and 684 were not. Up to 36 months follow-up, the relative risk of death in the rehabilitated group was 0.75, equivalent to a 25% reduction in mortality. The difference in mortality between the two groups was much higher during the first three months following intervention, with rehabilitated children having a higher mean weight gain during the first three months with weight gain differences lasting up to 18 months. Low-cost, outreach NRCs were therefore found to be effective both in the short term and in the mid term in improving the nutritional situation and reducing the mortality of severely malnourished children.

Postnatal hypothermia and cold stress among newborn infants in Nepal monitored by continuous ambulatory recording.

AIMS: To describe the pattern of hypothermia and cold stress after delivery among a normal neonatal population in Nepal; to provide practical advice for improving thermal care in a resource limited maternity hospital. METHODS: The principal government funded maternity hospital in Kathmandu, Nepal, with an annual delivery rate of 15,000 (constituting 40% of all Kathmandu Valley deliveries), severe resource limitations (annual budget Pounds 250,000), and a cold winter climate provided the setting. Thirty five healthy term neonates not requiring special care were enrolled for study within 90 minutes of birth. Continuous ambulatory temperature monitoring, using microthermistor skin probes for forehead and axilla, a flexible rectal probe, and a black ball probe placed next to the infant for ambient temperature, was carried out. All probes were connected to a compact battery powered Squirrel Memory Logger, giving a temperature reading to 0.2 degree C at five minute intervals for 24 hours. Severity and duration of hypothermia, using cutoff values of core temperature less than 36 degrees C, 34 degrees C, and 32 degrees C; and cold stress, using cutoff values of skin-core (forehead-axilla) temperature difference greater than 3 degrees C and 4 degrees C were the main outcome measures. RESULTS: Twenty four hour mean ambient temperatures were generally lower than the WHO recommended level of 25 degrees C (median 22.3 degrees C, range 15.1-27.5 degrees C). Postnatal hypothermia was prolonged, with axillary core temperatures only reaching 36 degrees C after a mean of 6.4 hours (range 0-21.1; SD 4.6). There was persistent and increasing cold stress over the first 24 hours with the core-skin (axillary-forehead) temperature gap exceeding 3 degrees C for more than half of the first 24 hours. CONCLUSIONS: Continuous ambulatory recording identifies weak links in the "warm chain" for neonates. The severity and duration of thermal problems was greater than expected even in a hospital setting where some of the WHO recommendations had already been implemented.

Neonatal hypoglycaemia in Nepal 1. Prevalence and risk factors.

AIMS: To measure the prevalence of hypoglycaemia among newborn infants in Nepal, where classic risk factors prevail, and to evaluate their importance. METHODS: A cross sectional study was done of 578 term newborn infants aged 0 to 48 hours on the postnatal wards of a government maternity hospital in Kathmandu, with unmatched case-control analysis of risk factors for moderate hypoglycaemia (less than 2.0 mmol /l). RESULTS: Two hundred and thirty eight (41%) newborn infants had mild (less than 2.6 mmol/l) and 66 (11%) moderate hypoglycaemia. Significant independent risk factors for moderate hypoglycaemia included postmaturity (OR 2.62), birthweight under 2.5 kg (OR 2.11), small head size (OR 0.59), infant haemoglobin >210 g/l (OR 2.77), and raised maternal thyroid stimulating hormone (TSH) (OR 3.08). Feeding delay increased the risk of hypoglycaemia at age 12-24 hours (OR 4.09). Disproportionality affected the risk of moderate hypoglycaemia: lower with increasing ponderal index (OR 0.29), higher as the head circumference to birthweight ratio increased (OR 1.41). Regression expressing blood glucose concentration as a continuous variable revealed associations with infant haemoglobin (negative) and maternal haemoglobin (positive), but no other textbook risk factors. CONCLUSIONS: Neonatal hypoglycaemia is more common in a developing country, but may not be a clinical problem unless all fuel availability is reduced. Some textbook risk factors, such as hypothermia, disappear after controlling for confounding variables. Early feeding could reduce moderate hypoglycaemia in the second 12 hours of life. The clinical significance of raised maternal TSH and maternal anaemia as prenatal risk factors requires further research.

Neonatal hypoglycaemia in Nepal 2. Availability of alternative fuels.

AIMS: To study early neonatal metabolic adaptation in a hospital population of neonates in Nepal. METHODS: A cross sectional study was made of 578 neonates, 0 to 48 hours after birth, in the main maternity hospital in Kathmandu. The following clinical and nutritional variables were assessed: concentrations and age profiles of blood glucose, hydroxybutyrate, lactate, pyruvate, free fatty acids (FFA) and glycerol; associations between alternative fuel levels and hypoglycaemia; and regression of possible risk factors for ketone availability. RESULTS: Risk factors for impaired metabolic adaptation were common, especially low birthweight (32%), feeding delays, and cold stress. Blood glucose and ketones rose with age, but important age effects were also found for risk factors like hypothermia, thyroid hormone activities, and feeding practices. Alternative fuel concentrations, except FFA, were significantly reduced in infants with moderate hypoglycaemia during the first 48 hours after birth. Unlike earlier studies, small for gestational age (SGA) infants had significantly higher hydroxybutyrate:glucose ratios which suggested counter regulatory ketogenesis. Hypoglycaemic infants were not hyperinsulinaemic. Regression analysis showed risk factors for impaired counter regulation which included male and large infants, hypothermia, and poorer infant thyroid function. SGA infants and those whose mothers had received no antenatal care had increased counter regulation. CONCLUSIONS: Alternative fuels are important in the metabolic assessment of neonates, and they might provide effective cerebral metabolism even during moderate hypoglycaemia. Hypoglycaemic infants generally had lower concentrations of alternative fuels through either reduced availability or increased consumption. SGA and post term infants increased counter regulatory ketogenesis with early neonatal hypoglycaemia, but hypothermia, male gender, and low infant T4 were associated with impaired counter regulation after birth.

Comparison of two cotside methods for the detection of hypoglycaemia among neonates in Nepal.

AIMS: To compare two cotside methods of blood glucose measurement (HemoCue and Reflolux II) against a standard laboratory method for the detection of neonatal hypoglycaemia in a developing country maternity hospital where hypoglycaemia is common. METHODS: 94 newborn infants and 75 of their mothers had blood glucose assessed on the same venous sample using three different methods in the Special Care Baby Unit and postnatal wards, Prasuti Griha Maternity Hospital, Kathmandu, Nepal: HemoCue and Reflolux II at the cotside; Roche Ultimate glucose oxidase method (GOM) in the laboratory. RESULTS: The mean (SD) values for blood glucose in newborn infants were GOM 2.5 (1.1) mmol/l; Reflolux II 2.1 (0.9); and HemoCue 4.2 (1.2). For mothers the values were GOM 5.3 (1.2) mmol/l; Reflolux II 3.6 (1.2); and HemoCue 5.6 (1.0). Bland-Altman plots showed that Reflolux II consistently underreads GOM blood glucose in neonates by 0.5 mmol/l (SD 0.7) and that HemoCue overreads glucose by 1.7 mmol/l (SD 0.8). For the detection of hypoglycaemia (< 2.0 mmol/l), Reflolux II achieved a sensitivity of 83%, a specificity of 62%, and a likelihood ratio of 2.2. HemoCue produced a sensitivity of 0% and a specificity of 100% using measured values. If 2.0 mmol were subtracted from all Hemocue values this rose to 81% and 68% and a likelihood ratio of 2.5. CONCLUSION: Although more accurate than Reflolux II for the measurement of blood glucose in mothers, HemoCue overreads glucose concentrations in neonates and is therefore potentially dangerous as a screening method for neonatal hypoglycaemia. Reflolux II is useful as a screening method for high risk infants (low birthweight, post-term) and could achieve a post-test probability of detecting hypoglycaemia in a high risk setting like Nepal of 50-60%.

Impact and sustainability of a "baby friendly" health education intervention at a district hospital in Bihar, India.

OBJECTIVES: To evaluate the impact and sustainability of a baby friendly training intervention for staff at an Indian district hospital on initiation of breast feeding and use of prelacteal feeds by mothers. DESIGN: Intervention study with assessment by interviewing mothers. SUBJECTS: 172 mothers recruited before the intervention, 195 recruited immediately after the intervention, and 101 recruited six months later. SETTING: District hospital in a small town in Bihar, India. MAIN OUTCOME MEASURES: Age of infant when breast feeding started, use of prelacteal feeds, and colostrum feeding. INTERVENTION: 10 day training programme for doctors, nurses, and midwives, explaining the benefits and feasibility of early breast feeding and dangers of prelacteal feeds together with instruction on explaining this information to mothers. RESULTS: Breast feeding was started within 24 hours of birth by 53 (29%) of control mothers, 164 (84%) in the early follow up group, and 60 (59%) in the late follow up group. Prelacteal feeds were used by 165 (96%), 84 (43%), and 78 (77%) respectively. Only 36 mothers in the late follow up group reported receiving education on feeding. Mothers in this group who had received the education were significantly more likely than mothers who received no education to breast feed early (28 (78%) v 11 (17%), P < 0.001) and not use prelacteal feeds (21 (58%) v 2 (3%), P < 0.001). CONCLUSIONS: Training doctors and midwives greatly improves the feeding practices of mothers. However, the impact of the training fell off quickly and refresher training is needed to sustain the improvement.

PIP: A health education intervention implemented at a district hospital in Bihar, India, sought to encourage new mothers to abandon harmful traditional practices such as delayed breast feeding initiation, disposal of colostrum, and prelacteal feeds. Hospital physicians, nurses, and midwives were exposed to a 10-day training program focused on "baby friendly" practices. In the 20 days following the staff intervention, 195 mothers were enrolled in the study and interviewed at home two weeks after delivery; also interviewed at home were 172 controls who delivered before the staff training. An additional 101 mothers were enrolled and interviewed six months after the staff training. Most mothers were illiterate Hindus from rural areas. Breast feeding was initiated within 24 hours by 164 mothers (84%) in the early group, 60 (59%) in the late group, and 53 (29%) mothers in the control group. The percentages of mothers giving prelacteal feeds were 43%, 77%, and 96%, respectively. Of note was the finding that only 36 mothers (36%) in the second intervention group reported having received guidance from staff on infant feeding. Overall, these findings suggest that training hospital staff in infant feeding practices has a beneficial effect on maternal behaviors, but this effect declines quickly over time as a result of staff turnover and loss of interest. Refresher training every six months is recommended for program sustainability.

Risk factors for neonatal encephalopathy in Kathmandu, Nepal, a developing country: unmatched case-control study.

OBJECTIVE: To determine the risk factors for neonatal encephalopathy among term infants in a developing country. DESIGN: Unmatched case-control study. SETTING: Principal maternity hospital of Kathmandu, Nepal. SUBJECTS: All 131 infants with neonatal encephalopathy from a population of 21 609 infants born over an 18 month period, and 635 unmatched infants systematically recruited over 12 months. MAIN OUTCOME MEASURES: Adjusted odds ratio estimates for antepartum and intrapartum risk factors. RESULTS: The prevalence of neonatal encephalopathy was 6.1 per 1,000 live births of which 63% were infants with moderate or severe encephalopathy. The risk of death from neonatal encephalopathy was 31%. The risk of neonatal encephalopathy increased with increasing maternal age and decreasing maternal height. Antepartum risk factors included primiparity (odds ratio 2.0) and non-attendance for antenatal care (2.1). Multiple births were at greatly increased risk (22). Intrapartum risk factors included non-cephalic presentation (3.4), prolonged rupture of membranes (3.8), and various other complications. Particulate meconium was strongly associated with encephalopathy (18). Induction of labour with oxytocin was associated with encephalopathy in 12 of 41 deliveries (5.7). Overall, 78 affected infants (60%) compared with 36 controls (6%) either had evidence of intrapartum compromise or were born after an intrapartum difficulty likely to result in fetal compromise. A concentration of maternal haemoglobin of less than 8.0 g/dl in the puerperium was significantly associated with encephalopathy (2.5) as was a maternal thyroid stimulating hormone concentration greater than 5 mIU/l (2.1). CONCLUSIONS: Intrapartum risk factors remain important for neonatal encephalopathy in developing countries. There is some evidence of a protective effect from antenatal care. The use of oxytocin in low income countries where intrapartum monitoring is suboptimal presents a major risk to the fetus. More work is required to explore the association between maternal deficiency states and neonatal encephalopathy.

PIP: This unmatched case-control study determined the risk factors for neonatal encephalopathy among term infants in Kathmandu, Nepal. Study participants included 131 infants with neonatal encephalopathy born between January 1995 and July 1996, and 635 unmatched infants systematically recruited over 12 months. The prevalence of neonatal encephalopathy was 6.1% per 1000 live births, of which 63% were infants with moderate encephalopathy. Antepartum risk factors included multiple births (odds ratio, OR = 22), primiparity (OR = 2.0), and nonattendance for antenatal care (OR = 2.1). Intrapartum risk factors were particulate meconium (OR = 18), noncephalic presentation (OR = 3.4), prolonged rupture of membranes (OR = 3.8), and other complications. In addition, induction of labor with oxytocin was associated with encephalopathy in 12 of 41 deliveries (OR = 5.7). Overall, 78 affected infants (60%) compared with 36 controls (6%) either had evidence of intrapartum compromise or were born after an intrapartum difficulty likely to result in fetal compromise. Moreover, maternal hemoglobin concentration 8.0 g/dl (OR = 2.5) and thyroid stimulating hormone 5 ml U/l (OR = 2.1) were associated with encephalopathy. Intrapartum risk factors remain important for neonatal encephalopathy in developing countries. There is some evidence of a protective effect from antenatal care. The use of oxytocin in low-income countries where intrapartum monitoring is suboptimal presents a major risk to the fetus. Further studies are required to explore the association between maternal deficiency states and neonatal encephalopathy.

The effects of postnatal health education for mothers on infant care and family planning practices in Nepal: a randomised controlled trial.

OBJECTIVES: To evaluate impact of postnatal health education for mothers on infant care and postnatal family planning practices in Nepal. DESIGN: Randomised controlled trial with community follow up at 3 and 6 months post partum by interview. Initial household survey of study areas to identify all pregnant women to facilitate follow up. SETTING: Main maternity hospital in Kathmandu, Nepal. Follow up in urban Kathmandu and a periurban area southwest of the city. SUBJECTS: 540 mothers randomly allocated to one of four groups: health education immediately after birth and three months later (group A), at birth only (group B), at three months only (group C), or none (group D). INTERVENTIONS: Structured baseline household questionnaire; 20 minute, one to one health education at birth and three months later. MAIN OUTCOME MEASURES: Duration of exclusive breast feeding, appropriate immunisation of infant, knowledge of oral rehydration solution and need to continue breast feeding in diarrhoea, knowledge of infant signs suggesting pneumonia, uptake of postnatal family planning. RESULTS: Mothers in groups A and B (received health education at birth) were slightly more likely to use contraception at six months after birth compared with mothers in groups C and D (no health education at birth) (odds ratio 1.62, 95% confidence interval 1.06 to 2.5). There were no other significant differences between groups with regards to infant feeding, infant care, or immunisation. CONCLUSIONS: Our findings suggest that the recommended practice of individual health education for postnatal mothers in poor communities has no impact on infant feeding, care, or immunisation, although uptake of family planning may be slightly enhanced.

An Apgar score of three or less at one minute is not diagnostic of birth asphyxia but is a useful screening test for neonatal encephalopathy.

OBJECTIVE: To evaluate the relationship between an Apgar score of three or less at one minute of life and the subsequent risk of developing neonatal encephalopathy (NE). DESIGN: Prospective. SETTING: The principal maternity hospital of Kathmandu, Nepal, a low income country, where over 50% of the local population deliver. METHODS: All liveborn infants over a 12 month period with a birthweight of 500 g or more were assessed by the Apgar scoring system at one minute of age. All term infants with neurological abnormalities presenting in the first day of life were systematically examined and described according to a conventionally defined encephalopathy grading system. Major congenital malformations and neonatal infections were excluded. RESULTS: Over 12 months there were 14,771 total births of a weight of 500 g or more of which 14,371 were live births and 400 were stillbirths. Of 734 infants with 1 min Apgar of three or less, 91 developed NE. The positive and negative predictive values of 1 min Apgar of three or less for NE were 11.4% and 99.9%, respectively. The probability of developing NE rose from 0.6% (amongst all infants born at this hospital) to 11.2% (amongst infants born with a one minute Apgar of three or less). CONCLUSIONS: An Apgar score of 3 or less at one minute is a useful screening test for clinically significant birth asphyxia (NE). It overestimates by eight fold the scale of the birth asphyxia problem, but identifies a high risk group requiring further observation of their neurological condition.
