Causes and outcome of young infant admissions to a Kenyan district hospital

Prevalence, Scope and Quality of Extemporaneous Medications in Selected Healthcare Facilities and Implications for Pharmacy Practice

Background: Extemporaneous compounding is the preparation of medicines for individual patients when no commercially available authorized form exists. Unlike registered medications, these products are not subjected to various tests for quality by Regulatory Authorities. Data on compounded medications in Ghana is currently inadequate or unavailable. There is the need to collate data that can be used to influence policy and to regulate preparation of extemporaneous products. Aim: To establish the prevalence, scope and quality of extemporaneously compounded medicines at selected hospitals in Accra, Ghana. Methodology: Prescriptions presented at the pharmacies in selected hospitals were reviewed to determine the requests that needed to be extemporaneously prepared as well as the prevalence and the scope of formulations. Three of the most frequently compounded medications were procured and subjected to microbial contamination tests using the pour plate method followed by differential tests if microbes were present. Content analysis of the active ingredients was determined using High Performance Liquid Chromatography (HPLC). Results: 641 requests comprising 49 different extemporaneous products were collated from the hospitals studied. Hydroxyurea, furosemide and spironolactone suspensions were the three most frequently prescribed. Patients aged from 0-2 years had majority of the prescriptions. Conclusion: A population of patients still exist who depend on compounding for their drug needs. 49 different formulations were prepared at one of the hospitals visited. Samples of products analyzed were of good quality.

Comparison of prognosis between hyperbilirubinemic infants with and without hypernatremia

OBJECTIVES

Hypernatremia may facilitate the diffusion of bilirubin through the blood-brain barrier and increase the risk of bilirubin encephalopathy. This study was conducted to compare the prognosis of jaundice infants with those with jaundice and hypernatremia.

METHODS

A total of 615 term infants with idiopathic jaundice with or without hypernatremia were enrolled in this cohort study with 24-months follow-up at Ghaem Hospital, Mashhad, Iran, between 2010 and 2022. An in-house questionnaire including the laboratory evaluation and neonatal characteristics was used as the data collection tool. The follow-up of neonatal development status was performed using the Denver test II at 6, 12, 18, and 24 months after discharging from hospital.

RESULTS

Normal outcomes were seen in 555 (90.2%) out of 615 studied infants, while 60 cases (9.8%) showed abnormal outcomes. Serum levels of sodium (P = 0.017), bilirubin (P = 0.001), urea (P = 0.024), and creatinine (P = 0.011) as well as hyperthermia (P = 0.046) and unconsciousness (P = 0.005) showed significant differences between the two groups. Approximately 16% of the newborns with both jaundice and hypernatremia, and 9% of those with only jaundice had unfavorable prognoses. Also, bilirubin level had the most predictive power (91.3%).

CONCLUSIONS

Our results suggest that hypernatremia or jaundice alone, may affect the prognosis of infants aged 2 years; but jaundice and hypernatremia together, will intensify the developmental problems in jaundice infants. However, the role of hyperbilirubinemia in the incidence of complications is more than hypernatremia.

Neurocognitive outcomes of children exposed to and living with HIV aged 3-5 years in Kilifi, Kenya

Introduction

Globally, 1.7 million children are living with HIV, with the majority of them residing in sub-Saharan Africa. Due to reduced rates of vertical transmission of HIV, there is an increasing population of children born to HIV-infected mothers who remain uninfected. There is a growing concern around the development of these children in the antiretroviral therapy era. This study examined the neurocognitive outcomes of children who are HIV-exposed infected (CHEI), HIV-exposed uninfected (CHEU) and HIV-unexposed uninfected (CHUU) and explored the relationship between child neurocognitive outcomes and child's biomedical and caregivers' psychosocial factors.

Methods

CHEI, CHUU and CHEU aged 3-5 years and their caregivers were recruited into the study. Neurocognitive outcomes were assessed using a validated battery of assessments. One-way analysis of variance and covariance (ANOVA and ANCOVA) were used to evaluate differences among the three groups by neurocognitive outcomes. Linear regression models were used to investigate the association between child neurocognitive outcomes and biomedical factors (nutritional status, HIV disease staging) and caregivers' psychosocial factors [symptoms of common mental disorders (CMDs) and parenting behaviour].

Results

The study included 153 children and their caregivers: 43 (28.1%) CHEI, 52 (34.0%) CHEU and 58 (39.9%) CHUU. ANOVA and ANCOVA revealed a significant difference in cognitive ability mean scores across the child groups. Post hoc analysis indicated that CHEU children had higher cognitive ability mean scores than the CHUU group. Better nutritional status was significantly associated with higher cognitive ability scores (β = 0.68, 95% CI [0.18-1.18], p = 0.008). Higher scores of CMDs were negatively associated with inhibitory control (β = -0.28, 95% CI [-0.53 to 0.02], p = 0.036). While comparing HIV stages 2 and 3, large effect sizes were seen in working memory (0.96, CI [0.08-1.80]) and cognitive ability scores (0.83 CI [0.01-1.63]), indicating those in stage 3 had poor performance.

Conclusions

Neurocognitive outcomes were similar across CHEI, CHEU and CHUU, although subtle differences were seen in cognitive ability scores where CHEU had significantly higher cognitive mean scores than the CHUU. Well-designed longitudinal studies are needed to ascertain these findings. Nonetheless, study findings underscore the need for strategies to promote better child nutrition, mental health, and early antiretroviral therapy initiation.

Development and internal validation of a Neonatal Healthcare-associated infectiOn Prediction score (NeoHoP score) for very low birthweight infants in low-resource settings: a retrospective case-control study

BACKGROUND AND OBJECTIVES

Early diagnosis of neonatal infection is essential to prevent serious complications and to avoid unnecessary use of antibiotics. The prevalence of healthcare-associated infections (HAIs) among very low birthweight (VLBW; <1500 g) infants is 20%; and the mortality in low-resource settings can be as high as 70%. This study aimed to develop an Infection Prediction Score to diagnose bacterial HAIs.

METHODS

A retrospective cohort of VLBW infants investigated for HAI was randomised into two unmatched cohorts. The first cohort was used for development of the score, and the second cohort was used for the internal validation thereof. Potential predictors included risk factors, clinical features, interventions, and laboratory data. The model was developed based on logistic regression analysis.

RESULTS

The study population of 655 VLBW infants with 1116 episodes of clinically suspected HAIs was used to develop the model. The model had five significant variables: capillary refill time >3 s, lethargy, abdominal distention, presence of a central venous catheter in the previous 48 hours and a C reactive protein ≥10 mg/L. The area below the receiver operating characteristic curve was 0.868. A score of ≥2 had a sensitivity of 54.2% and a specificity of 96.4%.

CONCLUSION

A novel Infection Prediction Score for HAIs among VLBW infants may be an important tool for healthcare providers working in low-resource settings but external validation needs to be performed before widespread use can be recommended.

Parental detection of neonatal jaundice using a low-cost colour card: a multicentre prospective study

BACKGROUND

Since most infants are usually discharged before age 48-72 hours, peak bilirubin levels will almost always occur after discharge. Parents may be the first to observe the onset of jaundice after discharge, but visual assessment is unreliable. The jaundice colour card (JCard) is a low-cost icterometer designed for the assessment of neonatal jaundice. The objective of this study was to evaluate parental use of JCard to detect jaundice in neonates.

METHODS

We conducted a multicentre, prospective, observational cohort study in nine sites across China. A total of 1161 newborns ≥35 weeks of gestation were enrolled in the study. Measurements of total serum bilirubin (TSB) levels were based on clinical indications. The JCard measurements by parents and paediatricians were compared with the TSB.

RESULTS

JCard values of parents and paediatricians were correlated with TSB (r=0.754 and 0.788, respectively). The parents' and paediatricians' JCard values 9 had sensitivities of 95.2% vs 97.6% and specificities of 84.5% vs 71.7% for identifying neonates with TSB ≥153.9 µmol/L. The parents' and paediatricians' JCard values 15 had sensitivities of 79.9% vs 89.0% and specificities of 66.7% vs 64.9% for identifying neonates with TSB ≥256.5 µmol/L. Areas under the receiver operating characteristic curves of parents for identifying TSB ≥119.7, ≥153.9, ≥205.2, and ≥256.5 µmol/L were 0.967, 0.960, 0.915, and 0.813, respectively, and those of paediatricians were 0.966, 0.961, 0.926 and 0.840, respectively. The intraclass correlation coefficient was 0.933 between parents and paediatricians.

CONCLUSION

The JCard can be used to classify different levels of bilirubin, but it is less accurate with high bilirubin levels. The JCard diagnostic performance of parents was slightly lower than that of paediatricians.

Trends in inpatient and post-discharge mortality among young infants admitted to Kilifi County Hospital, Kenya: a retrospective cohort study

OBJECTIVES

To describe admission trends and estimate inpatient and post-discharge mortality and its associated exposures, among young infants (YI) admitted to a county hospital in Kenya.

DESIGN

Retrospective cohort study.

SETTING

Secondary level hospital.

PARTICIPANTS

YI aged less than 60 days admitted to hospital from January 2009 to December 2019: 12 271 admissions in 11 877 individuals. YI who were resident within a Kilifi Health and Demographic Surveillance System (KHDSS): n=3625 with 4421 admissions were followed-up for 1 year after discharge.

PRIMARY AND SECONDARY OUTCOME MEASURES

Inpatient and 1-year post-discharge mortality, the latter in KHDSS residents.

RESULTS

Of 12 271 YI admissions, 4421 (36%) were KHDSS-resident. Neonatal sepsis, preterm complications and birth asphyxia accounted for 83% of the admissions. The proportion of YI among under-5s admissions increased from 19% in 2009 to 34% in 2019 (P_trend=0.02). Inpatient case fatality was 16%, with 66% of the deaths occurring within 48 hours of admission. The introduction of free maternity care in 2013 was not associated with a change in admissions or inpatient mortality among YI. During 1-year post-discharge, 208/3625 (5.7%) YI died, 64.3 (95% CI 56.2 to 73.7) per 1000 infant-years. 49% of the post-discharge deaths occurred within 1 month of discharge, and 49% of post-discharge deaths occurred at home. Both inpatient and post-discharge deaths were associated with low admission weight. Inpatient mortality was associated with clinical signs of disease severity, while post-discharge mortality was associated with the length of hospitalisation, leaving against advice and referral to a specialised hospital.

CONCLUSIONS

YIs accounted for an increasing proportion of paediatric admissions and their overall mortality remains high. Post-discharge mortality accounts for a lower proportion of deaths but mortality rate is higher than among children aged 2-59 months. Services to address post-discharge mortality are needed and should focus on infants at higher risk.

Disruptions to healthcare quality and early child health outcomes: Evidence from health-worker strikes in Kenya

This paper measures the effects of disruptions to healthcare quality at birth on early child health outcomes in Kenya. To identify impacts, we exploit variation in the timing and location of health-worker strikes at individual hospitals across the country between 1999 and 2014. Using data from Demographic Health Surveys, we find that children born during strikes are more likely to suffer a neonatal death. We find similar results using separate data collected in two informal settlements in Nairobi located near hospitals with frequent strikes. These results show that interruptions to healthcare quality can have large immediate health impacts, and suggests that status quo hospital care provides positive benefits. We also find suggestive evidence of reductions in later health investments, measured by vaccine take-up, among those who survive. This study provides the first rigorous evidence on the consequences of health-worker strikes, a frequent but understudied phenomenon in Sub-Saharan Africa.

Healthcare utilization by children with neurological impairments and disabilities in rural Kenya: a retrospective cohort study combined with secondary analysis of audit data

Background: There is a paucity of data on healthcare utilization by children with neurological impairments (NI) in sub-Saharan Africa. We determined the rate, risk factors, causes, and outcomes of hospital admission and utilization patterns for rehabilitative care among children with NI in a defined rural area in Kenya. Methods: We designed two sub-studies to address the primary objectives. Firstly, we retrospectively observed 251 children aged 6–9 years with NI and 2162 age-matched controls to determine the rate, causes and outcomes of hospitalization in a local referral hospital. The two cohorts were identified from an epidemiological survey conducted in 2015 in a defined geographical area. Secondly, we reviewed hospital records to characterize utilization patterns for rehabilitative care. Results: Thirty-four in-patient admissions occurred in 8503 person-years of observation (PYO), yielding a crude rate of 400 admissions per 100 000 PYO (95% confidence interval (Cl): 286–560). The risk of admission was similar between cases and controls (rate ratio=0.70, 95%CI: 0.10–2.30, p = 0.31). The presence of electricity in the household was associated with reduced odds of admission (odds ratio=0.32, 95% Cl: 0.10–0.90, p < 0.01). Seizures and malaria were the main causes of admission. We confirmed six (0.3%) deaths during the follow-up period. Over 93% of outpatient paediatric visits for rehabilitative care were related to cerebral palsy and intellectual developmental delay. Health education (87%), rehabilitative exercises (79%) and assistive technology (64%) were the most common interventions. Conclusions: Surprisingly, the risk of hospitalization was not different between children with NI and those without, possibly because those with severe NI who died before this follow-up were under seclusion and restraint in the community. Evidence-based and tailored rehabilitative interventions are urgently required based on the existing secondary data.

2.5 Million Annual Deaths-Are Neonates in Low- and Middle-Income Countries Too Small to Be Seen? A Bottom-Up Overview on Neonatal Morbi-Mortality

(1) Background: Every year, 2.5 million neonates die, mostly in low- and middle-income countries (LMIC), in total disregard of their fundamental human rights. Many of these deaths are preventable. For decades, the leading causes of neonatal mortality (prematurity, perinatal hypoxia, and infection) have been known, so why does neonatal mortality fail to diminish effectively? A bottom-up understanding of neonatal morbi-mortality and neonatal rights is essential to achieve adequate progress, and so is increased visibility. (2) Methods: We performed an overview on the leading causes of neonatal morbi-mortality and analyzed the key interventions to reduce it with a bottom-up approach: from the clinician in the field to the policy maker. (3) Results and Conclusions: Overall, more than half of neonatal deaths in LMIC are avoidable through established and well-known cost-effective interventions, good quality antenatal and intrapartum care, neonatal resuscitation, thermal care, nasal CPAP, infection control and prevention, and antibiotic stewardship. Implementing these requires education and training, particularly at the bottom of the healthcare pyramid, and advocacy at the highest levels of government for health policies supporting better newborn care. Moreover, to plan and follow interventions, better-quality data are paramount. For healthcare developments and improvement, neonates must be acknowledged as humans entitled to rights and freedoms, as stipulated by international law. Most importantly, they deserve more respectful care.

Performance Comparison of Infection Prediction Scores in a South African Neonatal Unit: A Retrospective Case-Control Study

BACKGROUND AND OBJECTIVES

Infection prediction scores are useful ancillary tests in determining the likelihood of neonatal hospital-acquired infection (HAI), particularly in very low birth weight (VLBW; <1,500 g) infants who are most vulnerable to HAI and have high antibiotic utilization rates. None of the existing infection prediction scores were developed for or evaluated in South African VLBW neonates.

METHODS

We identified existing infection prediction scores through literature searches and assessed each score for suitability and feasibility of use in resource-limited settings. Performance of suitable scores were compared using a retrospective dataset of VLBW infants (2016-2017) from a tertiary hospital neonatal unit in Cape Town, South Africa. Sensitivity, specificity, predictive values, and likelihood ratios were calculated for each score.

RESULTS

Eleven infection prediction scores were identified, but only five were suitable for use in resource-limited settings (NOSEP1, Singh, Rosenberg, and Bekhof scores). The five selected scores were evaluated using data from 841 episodes of HAI in 659 VLBW infants. The sensitivity for the scores ranged between 3% (NOSEP1 ≥14; proven and presumed infection), to a maximum of 74% (Singh score ≥1; proven infection). The specificity of these scores ranged from 31% (Singh score ≥1; proven and presumed infection) to 100% (NOSEP1 ≥11 and ≥14, NOSEP-NEW-1 ≥11; proven and presumed infection).

CONCLUSION

Existing infection prediction scores did not achieve comparable predictive performance in South African VLBW infants and should therefore only be used as an adjunct to clinical judgment in antimicrobial decision making. Future studies should develop infection prediction scores that have high diagnostic accuracy and are feasible to implement in resource-limited neonatal units.

Risk factors for death in suspected severe bacterial infection in infants aged <90 days in Luanda, Angola

BACKGROUND

Yearly, about two million infants die during the first 28 days of life. Most of these deaths occur in sub-Saharan Africa and a third of those are caused by severe infections. The early identification of infants at risk of death is important when trying to prevent poor outcomes.

OBJECTIVE

The aim of this study was to identify risk factors for death among young infants with possible serious bacterial infection (pSBI) at hospital admission.

METHODS

This prospective, observational, single-site, descriptive study forms part of a larger study on bacterial meningitis in infants <90 days of age admitted to the Pediatric Hospital of Luanda, the capital of Angola, from February 1, 2016 to October 23, 2017. Infants with pSBI, a known outcome, and a final diagnosis were included.

RESULTS

Of 574 young infants with pSBI, 115 (20%) died in hospital. An altered level of consciousness, absence of spontaneous movements, dyspnea, CSF that is not clear, low CSF glucose, high CSF protein, heart rate over the median, and seizures were identified as risk factors for death in the univariate analysis. In the multivariate analysis, only heart rate over the median and seizures were independent predictors of death.

CONCLUSIONS

Easily recognizable clinical signs - tachycardia and seizures - may guide clinicians to identify infants at high risk of death due to severe bacterial infections in sub-Saharan Africa.

Clinical signs predictive of severe illness in young Pakistani infants

Objective

Early detection of specific signs and symptoms to predict severe illness is essential to prevent infant mortality. As a continuation of the results from the multicenter Young Infants Clinical Signs and Symptoms (YICSS) study, we present here the performance of the seven-sign algorithm in 3 age categories (0–6 days, 7–27 days and 28–59 days) in Pakistani infants aged 0–59 days.

Results

From September 2003 to November 2004, 2950 infants were enrolled (age group 0–6 days = 1633, 7–27 days = 817, 28–59 days = 500). The common reason for seeking care was umbilical redness or discharge (29.2%) in the 0–6 days group. Older age groups presented with cough (16.9%) in the 7–27 age group and (26.9%) infants in the 28–59 days group. Severe infection/sepsis was the most common primary diagnoses in infants requiring hospitalization across all age groups. The algorithm performed well in every age group, with a sensitivity of 85.9% and specificity of 71.6% in the 0–6 days age group and a sensitivity of 80.5% and specificity of 80.2% in the 28–59 days group; the sensitivity was slightly lower in the 7–27 age group (72.4%) but the specificity remained high (83.1%).

Mortality during and following hospital admission among school-aged children: a cohort study

Background: Far less is known about the reasons for hospitalization or mortality during and after hospitalization among school-aged children than among under-fives in low- and middle-income countries. This study aimed to describe common types of illness causing hospitalisation; inpatient mortality and post-discharge mortality among school-age children at Kilifi County Hospital (KCH), Kenya.

Methods: A retrospective cohort study of children 5−12 years old admitted at KCH, 2007 to 2016, and resident within the Kilifi Health Demographic Surveillance System (KHDSS). Children discharged alive were followed up for one year by quarterly census. Outcomes were inpatient and one-year post-discharge mortality.

Results: We included 3,907 admissions among 3,196 children with a median age of 7 years 8 months (IQR 74−116 months). Severe anaemia (792, 20%), malaria (749, 19%), sickle cell disease (408, 10%), trauma (408, 10%), and severe pneumonia (340, 8.7%) were the commonest reasons for admission. Comorbidities included 623 (16%) with severe wasting, 386 (10%) with severe stunting, 90 (2.3%) with oedematous malnutrition and 194 (5.0%) with HIV infection. 132 (3.4%) children died during hospitalisation. Inpatient death was associated with signs of disease severity, age, bacteraemia, HIV infection and severe stunting. After discharge, 89/2,997 (3.0%) children died within one year during 2,853 child-years observed (31.2 deaths [95%CI, 25.3−38.4] per 1,000 child-years). 63/89 (71%) of post-discharge deaths occurred within three months and 45% of deaths occurred outside hospital. Post-discharge mortality was positively associated with weak pulse, tachypnoea, severe anaemia, HIV infection and severe wasting and negatively associated with malaria. 

Conclusions: Reasons for admissions are markedly different from those reported in under-fives. There was significant post-discharge mortality, suggesting hospitalisation is a marker of risk in this population. Our findings inform guideline development to include risk stratification, targeted post-discharge care and facilitate access to healthcare to improve survival in the early months post-discharge in school-aged children.

Long-term neurocognitive and educational outcomes of neonatal insults in Kilifi, Kenya

BACKGROUND

There is little data on the long-term neurocognitive and educational outcomes among school-aged survivors of neonatal jaundice (NNJ) and hypoxic-ischemic encephalopathy (HIE) in Africa. This study investigates the long-term neurocognitive and educational outcomes and the correlates of these outcomes in school-aged survivors of NNJ or HIE in Kilifi, Kenya.

METHODS

We conducted a cross-sectional study on neurocognitive and educational outcomes among school-aged survivors (6-12 years) of NNJ (n = 134) and HIE (n = 107) and compared them to a community comparison group (n = 134). We assessed nonverbal intelligence, planning, working memory, attention, syntax, pragmatics, word-finding, memory, perceptual-motor, mathematical, and reading abilities. We also collected information on medical history, caregivers' mental health, and family environment.

RESULTS

The survivors of NNJ had lower mean total scores in word-finding [F (1, 250) = 3.89, p = 0.050] and memory [F (1, 248) = 6.74, p = 0.010] than the comparison group. The survivors of HIE had lower mean scores in pragmatics [F (1, 230) = 6.61, p = 0.011] and higher scores higher scores in non-verbal reasoning [F (1, 225) =4.10, p = 0.044] than the comparison group. Stunted growth was associated with almost all the outcomes in HIE.

CONCLUSION

Survivors of NNJ and HIE present with impairment in the multiple domains, which need to be taken into consideration in the planning of educational and rehabilitative services.

The Epidemiology of Hypoxemic Pneumonia among Young Infants in Malawi

We describe hypoxemic pneumonia prevalence in outpatient and inpatient settings, in-hospital mortality, and clinical guideline performance for identifying hypoxemia in young infants in Malawi. In this retrospective analysis of a prospective cohort study, we investigate infants younger than 2 months participating in pneumonia surveillance at seven hospitals and 18 outpatient health centers in Malawi between 2011 and 2014. Logistic regression, multiple imputation with chained equations, and pattern mixture modeling were used to determine the association between peripheral capillary oxyhemoglobin saturation (SpO₂) levels and hospital mortality. We describe outpatient clinician hospital referral recommendations based on clinical characteristics and SpO₂ distributions. Among 1,879 analyzed cases, SpO₂ < 90% was more prevalent among outpatient health center cases compared with hospitalized cases (22.6% versus 13.5%, 95% CI: 17.6-28.4% and 12.0-15.3%, respectively). A larger proportion of hospitalized infants had signs of respiratory distress compared with infants at health centers (67.7% versus 56.6%, P < 0.001) and most hospitalized infants were boys (56.7% versus 40.6%, P < 0.001). An SpO₂ of 90-92% and < 90% was associated with similarly increased odds of in-hospital mortality (adjusted odds ratio [aOR]: 4.3 and 4.4, 95% CI: 1.7-11.1 and 1.8-10.5, respectively). Unrecorded, or unobtainable, SpO₂ was highly associated with mortality (n = 127, aOR: 18.1; 95% CI: 7.6-42.8). Four of 22 (18%) infants at health centers who did not meet clinical referral criteria had an SpO₂ ≤ 92%. Clinicians should consider hospital referral in young infants with a SpO₂ ≤ 92%. Infants with unobtainable SpO₂ readings should be considered a high-risk group, and hospital referral of these cases may be appropriate.

Neonatal jaundice and developmental impairment among infants in Kilifi, Kenya

BACKGROUND

Neonatal jaundice (NNJ) is common in sub-Saharan Africa (SSA), and it is associated with sepsis. Despite the high incidence, little has been documented about developmental impairments associated with NNJ in SSA. In particular, it is not clear if sepsis is associated with greater impairment following NNJ.

METHODS

We followed up 169 participants aged 12 months (57 cases and 112 controls) within the Kilifi Health Demographic Surveillance System. The diagnosis of NNJ was based on clinical laboratory measurement of total serum bilirubin on admission, whereas the developmental outcomes were assessed using the Developmental Milestones Checklist and Kilifi Development Inventory.

RESULTS

There were significant differences between the cases and controls in all developmental domains. Cases scored lower in language functioning (mean [M] = 6.5, standard deviation [SD] = 4.3 vs. M = 8.9, SD = 4.6; p < .001); psychomotor functioning (Mdn = 23, interquartile range [IQR] = 17-34 vs. Mdn = 31.0, IQR = 22.0-44.0; Mann-Whitney U = 4,122, p = .002); and socio-emotional functioning ([Mdn = 30.0, IQR = 27.0-33.0 vs. Mdn = 34.0, IQR = 30.0-37.0], Mann-Whitney U = 4,289, p < .001). There was no evidence of association between sepsis and psychomotor (r_pb = -.2, p = .214), language (r_pb = -.1, p = .510), and socio-emotional functioning (r_pb = .0, p = .916). Significant and medium to large portions of the variance (34-64%) in the developmental outcomes among children who survived NNJ were associated with home birth, low maternal education, and feeding problems during the first days of life.

CONCLUSIONS

NNJ is associated with developmental impairments in the early childhood years; however, NNJ associated with sepsis does not lead to more severe impairment. Prenatal and postnatal care services are needed to reduce the negative impact of NNJ for children from low resourced settings.

Determinants of neonatal jaundice among neonates admitted to five referral hospitals in Amhara region, Northern Ethiopia: an unmatched case-control study

BACKGROUND

Neonatal jaundice is associated with a significant risk of neonatal morbidity and mortality. It is a major cause of hospital neonatal intensive care unit admission and readmissions during the neonatal period. Hence, the study aimed to identify the determinant factors of neonatal jaundice among neonates admitted at five referral hospitals in Amhara region, Northern Ethiopia.

METHOD

A hospital-based unmatched case-control study design was employed, on 447 neonates (149 cases and 298 controls) at referral hospitals in Amhara region, Northern Ethiopia, from 1 March to 30 July 2019. Consecutive sampling method was used to select both the cases and controls. The collected data were entered into Epi data V.4.2 and then exported into SPSS window V.24 for analysis. Bivariable and multivariable analysis were carried out by using binary logistic regression. A p value of <0.05 was considered as significant difference between cases and controls for the exposure variable of interest.

RESULTS

The median (±IQR) age of neonate at the time of admission and gestational age were 3±2 days and 38 (±3) weeks, respectively. Prolonged duration of labour (adjusted OR (AOR)=2.45, 95% CI 1.34 to 4.47), being male sex (AOR=3.54, 95% CI 1.99 to 6.29), low birth weight (AOR=5.06, 95% CI 2.61 to 9.82), birth asphyxia (AOR=2.88, 95% CI 1.38 to 5.99), sepsis (AOR=2.49, 95% CI 1.22 to 5.11) and hypothermia (AOR=2.88, 95% CI 2.63 to 14.02) were the determinant factors for neonatal jaundice.

CONCLUSIONS

Prolonged duration of labour, hypothermia, sepsis, birth asphyxia, low birth weight and sex of neonate were independent determinants of neonatal jaundice. Early recognition and management of identified modifiable determinants are the recommended interventions.

Oxygen systems to improve clinical care and outcomes for children and neonates: A stepped-wedge cluster-randomised trial in Nigeria

BACKGROUND

Improving oxygen systems may improve clinical outcomes for hospitalised children with acute lower respiratory infection (ALRI). This paper reports the effects of an improved oxygen system on mortality and clinical practices in 12 general, paediatric, and maternity hospitals in southwest Nigeria.

METHODS AND FINDINGS

We conducted an unblinded stepped-wedge cluster-randomised trial comparing three study periods: baseline (usual care), pulse oximetry introduction, and stepped introduction of a multifaceted oxygen system. We collected data from clinical records of all admitted neonates (<28 days old) and children (28 days to 14 years old). Primary analysis compared the full oxygen system period to the pulse oximetry period and evaluated odds of death for children, children with ALRI, neonates, and preterm neonates using mixed-effects logistic regression. Secondary analyses included the baseline period (enabling evaluation of pulse oximetry introduction) and evaluated mortality and practice outcomes on additional subgroups. Three hospitals received the oxygen system intervention at 4-month intervals. Primary analysis included 7,716 neonates and 17,143 children admitted during the 2-year stepped crossover period (November 2015 to October 2017). Compared to the pulse oximetry period, the full oxygen system had no association with death for children (adjusted odds ratio [aOR] 1.06; 95% confidence interval [CI] 0.77-1.46; p = 0.721) or children with ALRI (aOR 1.09; 95% CI 0.50-2.41; p = 0.824) and was associated with an increased risk of death for neonates overall (aOR 1.45; 95% CI 1.04-2.00; p = 0.026) but not preterm/low-birth-weight neonates (aOR 1.30; 95% CI 0.76-2.23; p = 0.366). Secondary analyses suggested that the introduction of pulse oximetry improved oxygen practices prior to implementation of the full oxygen system and was associated with lower odds of death for children with ALRI (aOR 0.33; 95% CI 0.12-0.92; p = 0.035) but not for children, preterm neonates, or neonates overall (aOR 0.97, 95% CI 0.60-1.58, p = 0.913; aOR 1.12, 95% CI 0.56-2.26, p = 0.762; aOR 0.90, 95% CI 0.57-1.43, p = 0.651). Limitations of our study are a lower-than-anticipated power to detect change in mortality outcomes (low event rates, low participant numbers, high intracluster correlation) and major contextual changes related to the 2016-2017 Nigerian economic recession that influenced care-seeking and hospital function during the study period, potentially confounding mortality outcomes.

CONCLUSIONS

We observed no mortality benefit for children and a possible higher risk of neonatal death following the introduction of a multifaceted oxygen system compared to introducing pulse oximetry alone. Where some oxygen is available, pulse oximetry may improve oxygen usage and clinical outcomes for children with ALRI.

Hypoxaemia in hospitalised children and neonates: A prospective cohort study in Nigerian secondary-level hospitals

BACKGROUND

Hypoxaemia is a common complication of pneumonia and a major risk factor for death, but less is known about hypoxaemia in other common conditions. We evaluated the epidemiology of hypoxaemia and oxygen use in hospitalised neonates and children in Nigeria.

METHODS

We conducted a prospective cohort study among neonates and children (<15 years of age) admitted to 12 secondary-level hospitals in southwest Nigeria (November 2015-November 2017) using data extracted from clinical records (documented during routine care). We report summary statistics on hypoxaemia prevalence, oxygen use, and clinical predictors of hypoxaemia. We used generalised linear mixed-models to calculate relative odds of death (hypoxaemia vs not).

FINDINGS

Participating hospitals admitted 23,926 neonates and children during the study period. Pooled hypoxaemia prevalence was 22.2% (95%CI 21.2-23.2) for neonates and 10.2% (9.7-10.8) for children. Hypoxaemia was common among children with acute lower respiratory infection (28.0%), asthma (20.4%), meningitis/encephalitis (17.4%), malnutrition (16.3%), acute febrile encephalopathy (15.4%), sepsis (8.7%) and malaria (8.5%), and neonates with neonatal encephalopathy (33.4%), prematurity (26.6%), and sepsis (21.0%). Hypoxaemia increased the adjusted odds of death 6-fold in neonates and 7-fold in children. Clinical signs predicted hypoxaemia poorly, and their predictive ability varied across ages and conditions. Hypoxaemic children received oxygen for a median of 2-3 days, consuming ∼3500 L of oxygen per admission.

INTERPRETATION

Hypoxaemia is common in respiratory and non-respiratory acute childhood illness and increases the risk of death substantially. Given the limitations of clinical signs, pulse oximetry is an essential tool for detecting hypoxaemia, and should be part of the routine assessment of all hospitalised neonates and children.

Aetiology of invasive bacterial infection and antimicrobial resistance in neonates in sub-Saharan Africa: a systematic review and meta-analysis in line with the STROBE-NI reporting guidelines

BACKGROUND

Aetiological data for neonatal infections are essential to inform policies and programme strategies, but such data are scarce from sub-Saharan Africa. We therefore completed a systematic review and meta-analysis of available data from the African continent since 1980, with a focus on regional differences in aetiology and antimicrobial resistance (AMR) in the past decade (2008-18).

METHODS

We included data for microbiologically confirmed invasive bacterial infection including meningitis and AMR among neonates in sub-Saharan Africa and assessed the quality of scientific reporting according to Strengthening the Reporting of Observational Studies in Epidemiology for Newborn Infection (STROBE-NI) checklist. We calculated pooled proportions for reported bacterial isolates and AMR.

FINDINGS

We included 151 studies comprising data from 84 534 neonates from 26 countries, almost all of which were hospital-based. Of the 82 studies published between 2008 and 2018, insufficient details were reported regarding most STROBE-NI items. Regarding culture positive bacteraemia or sepsis, Staphylococcus aureus, Klebsiella spp, and Escherichia coli accounted for 25% (95% CI 21-29), 21% (16-27), and 10% (8-10) respectively. For meningitis, the predominant identified causes were group B streptococcus 25% (16-33), Streptococcus pneumoniae 17% (9-6), and S aureus 12% (3-25). Resistance to WHO recommended β-lactams was reported in 614 (68%) of 904 cases and resistance to aminoglycosides in 317 (27%) of 1176 cases.

INTERPRETATION

Hospital-acquired neonatal infections and AMR are a major burden in Africa. More population-based neonatal infection studies and improved routine surveillance are needed to improve clinical care, plan health systems approaches, and address AMR. Future studies should be reported according to standardised reporting guidelines, such as STROBE-NI, to aid comparability and reduce research waste.

Correlation of 25-hydroxy vitamin D level with neonatal hyperbilirubinemia in term healthy newborn: A prospective hospital-based observation study

Background

Neonatal hyperbilirubinemia is one of the common entities that lead to frequent hospital admission of newborn. There are many risk factors that, when present, can lead to increased chances of neonatal hyperbilirubinemia. It is essential to identify these risk factors that are involved in the increased incidence of neonatal hyperbilirubinemia because its incidence can be decreased by modifying them.

Objective

To compare and determine any correlation of 25-hydroxy vitamin D levels of newborn and their mothers with the serum bilirubin level of newborn.

Methodology

This was a case–control study conducted in a tertiary care hospital on 100 newborn who were divided into two groups (50 in each group) on the basis of their serum bilirubin level on the 5th day of life. Newborns having serum bilirubin levels in the physiological range were included in the control group, and newborns having serum bilirubin levels out of the physiological range and who needed treatment were included in the case group. The blood samples of both newborns and their mothers were collected on the 5th day and sent to the laboratory for serum bilirubin and 25-hydroxy vitamin D estimation.

Results

The mean serum vitamin D level of cases was found to be lower than that of controls in both newborn and their mothers. A statistically significant difference was noted only between the vitamin D level of newborn but not in mothers when cases and controls were compared. Negative, statistically insignificant correlation was seen between vitamin D level and serum bilirubin in cases and controls. However, correlation of the vitamin D level of cases and their serum bilirubin was statistically significant, with a correlation coefficient of −0.335 and a p value of 0.0172.

Conclusion

Term healthy newborn having hyperbilirubinemia, with serum bilirubin levels out of the physiological range, have significantly low vitamin D levels and show a statistically negatively correlation with neonatal hyperbilirubinemia (which is out of the physiological range). Thus, decreased vitamin D can be included in the list of risk factors for neonatal jaundice.

The effects of hyperbilirubinaemia on synaptic plasticity in the dentate gyrus region of the rat hippocampus in vivo

INTRODUCTION

The aim of our study is to investigate the effect of hyperbilirubinaemia on synaptic plasticity in the dentate gyrus (DG) region of the rat hippocampus.

MATERIAL AND METHODS

Seven-day-old healthy Sprague Dawley (SD) rats were randomly divided into a control group and an experiment group (n = 20 in each group). The input/output (I/O) functions, paired-pulse reactions (PPR), excitatory postsynaptic potential (EPSP), and population spike (PS) amplitude were measured in the DG area of both groups of rats in response to stimulation applied to the lateral perforant path.

RESULTS

Compared with that in the control rats, the current-voltage curves of both EPSP slope and PS amplitude in the experimental rats were significantly depressed. The average peak facilitation was 187 ±16% in the control and 164 ±18% in the experiment group (F = 21.054, p < 0.01). The facilitation period duration of PS was 155 ms in the experimental rats, which was less than that of the controls (235 ms). In the control group, the long-term potentiation (LTP) amplitudes were 140 ±3.5% and 242 ±6%, when estimated from the EPSP slope and PS amplitude, respectively, which were significantly depressed to 124 ±3.4% (EPSP slope, F = 70.489, p < 0.01) and 138 ±8.6% (PS amplitude, F = 253.46, p < 0.01), respectively, in the experiment group.

CONCLUSIONS

These findings suggest that hyperbilirubinaemia could induce impairment of synaptic plasticity in the rat DG area in vivo, including I/O function, paired-pulse ratio (PPR), and LTP, which may be closely related to cognitive impairment.

A randomized control trial of phototherapy and 20% albumin versus phototherapy and saline in Kilifi, Kenya

Objective

The study evaluated the efficacy of phototherapy and 20% albumin infusion to reduce total serum bilirubin (TSB) in neonates with severe hyperbilirubinemia. The primary outcome was a reduction of TSB at the end of treatment. The secondary outcomes were the need for exchange transfusion, inpatient mortality, neurological outcomes at discharge, and development outcomes at 12-months follow-up.

Results

One hundred and eighteen neonates were randomly assigned to phototherapy and 20% albumin (n = 59) and phototherapy and saline (n = 69). The median age at admission was 5 (interquartile range (IQR) 3–6) days, and the median gestation was 36 (IQR 36–38) weeks. No significant differences were found in the change in TSB (Mann–Whitney U =609, p = 0.98) and rate of change in TSB per hour after treatment (Mann–Whitney U = 540, p = 0.39) between the two groups. There were no significant differences between the two groups in the proportion of participants who required exchange transfusion (χ² (2) = 0.36, p = 0.546); repeat phototherapy (χ² (2) = 2.37, p = 0.123); and those who died (χ² (2) = 0.92, p = 0.337). Trial registration The trial was registered in the International Standardized Randomized Controlled Trial Number (ISRCTN); trial registration number ISRCTN89732754.

Aetiology of neonatal sepsis in Nigeria, and relevance of Group b streptococcus: A systematic review

BACKGROUND

Group B Streptococcus (GBS) causes invasive infections in neonates and has been implicated as a cause of prelabour rupture of membranes, preterm delivery and stillbirths. The success of phase II trials of polyvalent polysaccharide GBS vaccines indicates that these infections are potentially preventable. Nigeria is the most populous country in Africa with one of the highest birth rates, one of the highest neonatal sepsis incidence rates and one of the highest mortality rates in the world. Therefore, before the possible introduction of preventive strategies such as intrapartum antibiotic prophylaxis or GBS vaccine into Nigeria, it is vital that there is accurate data on the aetiology of neonatal sepsis and on the incidence of GBS neonatal sepsis in particular. The objective of this study was to determine the incidence and aetiology of neonatal sepsis in Nigeria with a focus on GBS sepsis and also to assess the potential impact of a GBS vaccine.

METHODS

A literature search was conducted on the databases of African journals online, PubMed and Google Scholar for works conducted between 1987 to 2017. Case reports, reviews, and studies not stating specific culture methods or specific bacteria isolated were excluded. Data extracted included; incidence of neonatal sepsis, method of blood culture, blood volume, sample size, bacterial agents isolated and history of antibiotic use. PRISMA guidelines were followed and modified Down's and Black criteria used to evaluate the quality of studies.

RESULTS

A total of 5,114 studies were reviewed for neonatal sepsis out of which 24 consisting of a total of 2,280 cases were selected for final review. Nine studies met criteria for assessment of hospital based incidence of neonatal sepsis representing 31,305 hospital births. The incidence of neonatal sepsis was 18.2/1000 livebirths with range from 7-55/1000 livebirths while the GBS incidence was 0.06/1000 livebirths with range from 0-2/1000 live births. We discovered various limitations such as identification techniques that could result in underestimation of the true incidence of GBS sepsis. Pathogens such as Klebsiella pneumoniae and Staphylococcus aureus were more commonly isolated than GBS.

IMPLICATIONS OF KEY FINDINGS

The hospital based incidence of neonatal sepsis was high at 18.2/1000 live births while that due to GBS was 0.06/1000 live births. The burden of neonatal sepsis, including that attributable to GBS is substantial and could be reduced by preventive strategies such as intrapartum antibiotic prophylaxis or GBS vaccine. There is however very sparse meaningful data currently. Well planned prospective studies with larger sample sizes, more advanced isolation and identification techniques and those following up invasive disease cases for possible short and long term sequelae are needed-not only prior to possible introduction of the vaccine to determine the baseline epidemiology, but also thereafter to monitor its impact on the population. Strategies need to be developed to also reduce the morbidity and mortality attributable to other bacteria that have an incidence even greater than that of GBS.

Correlation between serum vitamin D level and neonatal indirect hyperbilirubinemia

BACKGROUND

Considering the significant prevalence of Neonatal Indirect Hyperbilirubinemia (NIH) and its irreversible neurological complications, identifying the factors involved in the prevalence of neonatal jaundice is essential. The present study was conducted to determine the relationship between serum vitamin D levels and the prevalence of NIH in infants admitted to Qods Hospital of Qazvin in Iran in 2015-16.

METHODS

In this case-control study, 30 term infants with NIH (the case group) were compared with 30 healthy, non- icteric, term infants (the control group) in terms of serum levels of 25-hydroxyvitamin D. The results were analyzed and compared between the two groups using t-test and the Chi-square test.

RESULTS

The mean and standard deviation of serum 25-hydroxyvitamin D levels were 10.76 ± 8.6 ng/dl in the case group and 14.88 ± 11.38 ng/dl in the control group. There were no significant differences between the two groups (P = 0.11).

CONCLUSION

The results suggest the lack of a relationship between vitamin D levels and NIH. However, further prospective studies are needed to conclude that vitamin D has no role in the pathogenesis of NIH.

An observational study of monitoring of vital signs in children admitted to Kenyan hospitals: an insight into the quality of nursing care?

Background

Measurement and correct interpretation of vital signs is part of routine clinical care. Repeated measurement enhances early recognition of deterioration, may help prevent morbidity and mortality and is a standard of care in most countries.

Objective

To examine documentation of vital signs by clinicians for admissions to paediatric wards in Kenyan hospitals, to describe monitoring frequency by nurses and explore factors influencing frequency.

Methods

Vital signs information (temperature, respiratory and pulse rate) for the first 48 hours of admission was collected from case records of children admitted with non-surgical conditions to 13 Kenyan county hospitals between September 2013 and April 2016. A mixed effect negative binomial regression model was used to explore whether the severity of illness (indicated by danger signs or severe diagnostic episodes) is associated with increased vital signs observation frequency.

Results

We examined 54 800 admission episodes with an overall mortality 6.1%. Nurse to bed ratios were very low (1:10 to 1:41 across hospitals). Admitting clinicians documented all or no vital signs in 57.0% and 8.4% cases respectively. For respiratory and pulse rates there was pronounced even end-digit preference (an indicator of incorrect information) and high frequency recording of specific values (P < 0.001) suggesting approximation. Monitoring frequency was explored in 41 738 children. Those with inpatient stays ≥48 hours were expected to have a vital signs count of 18, hospitals varied but most did not achieve this benchmark (median 9, range 2-30). There were clinically small but significant associations between vital signs count and presence of multiple severe illnesses or presence of severe pallor (adjusted relative risk ratio = 1.04, P < 0.01, 95% confidence interval CI = 1.02-1.06 and 1.05, P = 0.02, 95% CI = 1.01-1.09, respectively).

Conclusions

Data suggest accurate admission measures are sometimes missing especially for pulse and respiratory rates, possibly linked to manual measurement. Monitoring frequency is often low in the high risk population studied probably indicating how quality of nursing care is undermined by considerable human resource shortages.

Pulse oximetry values of neonates admitted for care and receiving routine oxygen therapy at a resource-limited hospital in Kenya

AIM

There are 2.7 million neonatal deaths annually, 75% of which occur in sub-Saharan Africa and South Asia. Effective treatment of hypoxaemia through tailored oxygen therapy could reduce neonatal mortality and prevent oxygen toxicity.

METHODS

We undertook a two-part prospective study of neonates admitted to a neonatal unit in Nairobi, Kenya, between January and December 2015. We determined the prevalence of hypoxaemia and explored associations of clinical risk factors and signs of respiratory distress with hypoxaemia and mortality. After staff training on oxygen saturation (SpO₂ ) target ranges, we enrolled a consecutive sample of neonates admitted for oxygen and measured SpO₂ at 0, 6, 12, 18 and 24 h post-admission. We estimated the proportion of neonates outside the target range (≥34 weeks: ≥92%; <34 weeks: 89-93%) with 95% confidence intervals (CIs).

RESULTS

A total of 477 neonates were enrolled. Prevalence of hypoxaemia was 29.2%. Retractions (odds ratio (OR) 2.83, 95% CI 1.47-5.47), nasal flaring (OR 2.68, 95% CI 1.51-4.75), and grunting (OR 2.47, 95% CI 1.27-4.80) were significantly associated with hypoxaemia. Nasal flaring (OR 2.85, 95% CI 1.25-6.54), and hypoxaemia (OR 3.06, 95% CI 1.54-6.07) were significantly associated with mortality; 64% of neonates receiving oxygen were out of range at ≥2 time points and 43% at ≥3 time points.

CONCLUSION

There is a high prevalence of hypoxaemia at admission and a strong association between hypoxaemia and mortality in this Kenyan neonatal unit. Many neonates had out of range SpO₂ values while receiving oxygen. Further research is needed to test strategies aimed at improving the accuracy of oxygen provision in low-resource settings.

The Treatment of Possible Severe Infection in Infants: An Open Randomized Safety Trial of Parenteral Benzylpenicillin and Gentamicin Versus Ceftriaxone in Infants <60 days of Age in Malawi

BACKGROUND

The World Health Organization recommends benzylpenicillin and gentamicin as antimicrobial treatment for infants with sepsis in low-income settings, and ceftriaxone or cefotaxime as an alternative. In a meta-analysis from 13 low-income settings, Staphylococcus aureus, Klebsiella spp. and Escherichia coli accounted for 55% of infants with sepsis. In a review of bacterial meningitis, resistance to third generation cephalosporins was >50% of all isolates, and 44% of Gram-negative isolates were gentamicin resistant. However, ceftriaxone may cause neonatal jaundice, and gentamicin may cause deafness. Therefore, we compared parenteral benzylpenicillin plus gentamicin with ceftriaxone as first-line treatment, assessing outcome and adverse events.

METHODS

This was an open randomized trial carried out in the Queen Elizabeth Central Hospital, Blantyre, Malawi, from 2010 to 2013. Infants <60 days of age with possible severe sepsis received either benzylpenicillin and gentamicin or ceftriaxone. Adverse events and outcomes were recorded until 6 months post discharge.

RESULTS

Three-hundred forty-eight infants were included in analyses. Outcome in the benzylpenicillin and gentamicin and ceftriaxone groups was similar; deaths were 13.7% and 16.5% and sequelae were 14.5% and 11.2%, respectively. More infants in the penicillin/gentamicin group required phototherapy: 15% versus 5%, P = 0.03. Thirteen (6%) survivors had bilateral hearing loss. There was no difference between the treatment groups. By 6 months post discharge, 11 more infants had died, and 17 more children were found to have sequelae.

CONCLUSIONS

Ceftriaxone and gentamicin are safe for infants in our setting. Infants should receive long-term follow-up as many poor outcomes occurred after hospital discharge.

The effects of prenatal HIV exposure on language functioning in Kenyan children: establishing an evaluative framework

BACKGROUND

HIV infection has been associated with impaired language development in prenatally exposed children. Although most of the burden of HIV occurs in sub-Saharan Africa, there have not been any comprehensive studies of HIV exposure on multiple aspects of language development using instruments appropriate for the population.

METHODS

We compared language development in children exposed to HIV in utero to community controls (N = 262, 8-30 months) in rural Kenya, using locally adapted and validated communicative development inventories.

RESULTS

The mean score of the younger HIV-exposed uninfected infants (8-15 months) was not significantly below that of the controls; however older HIV-exposed uninfected children had significantly poorer language scores, with HIV positive children scoring more poorly than community controls, on several measures.

CONCLUSIONS

Our preliminary data indicates that HIV infection is associated with impaired early language development, and that the methodology developed would be responsive to a more detailed investigation of the variability in outcome amongst children exposed to HIV, irrespective of their infection status.

Predictive value of cord blood bilirubin for hyperbilirubinemia in neonates at risk for maternal-fetal blood group incompatibility and hemolytic disease of the newborn

OBJECTIVE

To determine the predictive ability of cord blood bilirubin (CBB) for hyperbilirubinemia in a population at risk for maternal-fetal blood group incompatibility and hemolytic disease of the newborn.

STUDY DESIGN

This is a single center retrospective case-control study. Cases received phototherapy; controls did not. Cases were matched 1:3 to controls by gender and treating physician. Inclusion criteria included: ≥35 weeks gestation, CBB, and one or more total serum bilirubin (TSB) concentrations. The primary outcome was CBB. Secondary outcomes were a TSB >75th percentile, length of stay, and neonatal intensive care unit admission. The prognostic ability of CBB for phototherapy and TSB >75th percentile was assessed using area under the receiver operating characteristic (ROC) curve. Logistic regression analyses were performed to determine predictors for phototherapy and TSB >75th percentile.

RESULT

When compared to controls (n = 142), cases (n = 54) were more likely to have a positive Coombs' test (82% vs. 41% , p <  0.001) and TSB >75th percentile (85% vs. 21% , p <  0.001). When compared to controls, cases had a higher mean (±SD) CBB (2.5 ± 0.5 vs. 1.8 ± 0.4 mg/dL, p <  0.001). The area under the ROC curve (±SEM) for CBB for phototherapy and TSB >75th percentile was 0.87 ± 0.03 (p <  0.001, 95% CI 0.82, 0.93) and 0.87 ± 0.03 (p <  0.001, 95% CI 0.82, 0.92), respectively.

CONCLUSION

In this study, the mean CBB concentration was higher in neonates who received phototherapy compared to those who did not. CBB concentrations may help predict severe hyperbilirubinemia and phototherapy in a population at risk for hemolytic disease of the newborn.

Characteristics of admissions and variations in the use of basic investigations, treatments and outcomes in Kenyan hospitals within a new Clinical Information Network

BACKGROUND

Lack of detailed information about hospital activities, processes and outcomes hampers planning, performance monitoring and improvement in low-income countries (LIC). Clinical networks offer one means to advance methods for data collection and use, informing wider health system development in time, but are rare in LIC. We report baseline data from a new Clinical Information Network (CIN) in Kenya seeking to promote data-informed improvement and learning.

METHODS

Data from 13 hospitals engaged in the Kenyan CIN between April 2014 and March 2015 were captured from medical and laboratory records. We use these data to characterise clinical care and outcomes of hospital admission.

RESULTS

Data were available for a total of 30 042 children aged between 2 months and 15 years. Malaria (in five hospitals), pneumonia and diarrhoea/dehydration (all hospitals) accounted for the majority of diagnoses and comorbidity was found in 17 710 (59%) patients. Overall, 1808 deaths (6%) occurred (range per hospital 2.5%-11.1%) with 1037 deaths (57.4%) occurring by day 2 of admission (range 41%-67.8%). While malaria investigations are commonly done, clinical health workers rarely investigate for other possible causes of fever, test for blood glucose in severe illness or ascertain HIV status of admissions. Adherence to clinical guideline-recommended treatment for malaria, pneumonia, meningitis and acute severe malnutrition varied widely across hospitals.

CONCLUSION

Developing clinical networks is feasible with appropriate support. Early data demonstrate that hospital mortality remains high in Kenya, that resources to investigate severe illness are limited, that care provided and outcomes vary widely and that adoption of effective interventions remains slow. Findings suggest considerable scope for improving care within and across sites.

Evaluation of phototherapy with reflectors: A randomized controlled trial

BACKGROUND AND OBJECTIVES

Neonatal jaundice is one of the most prevalent clinical conditions requiring evaluation and management within the first few days of life. Phototherapy is the single most common intervention used for the treatment of neonatal jaundice. The aim of our study was to evaluate the efficacy and tolerability of phototherapy with reflectors compared to conventional phototherapy in controlling neonatal hyperbilirubinaemia.

PATIENTS AND METHODS

In this randomized controlled study, we studied neonates for one year (from June 2010 to June 2011) who were full term and healthy with uncomplicated jaundice and who were admitted to the neonatal intensive care unit (NICU) of El-Nasr General Hospital, Port-Said, Egypt. The subjects were randomized in two groups: group A (n = 30) received phototherapy with reflectors and group B (n = 30) received conventional phototherapy. Serum bilirubin levels were measured on admission and every 12 h thereafter. With declining readings, bilirubin was measured once daily until hospital discharge.

RESULTS

There was no significant difference in total serum bilirubin on admission between the two groups. On discharge, bilirubin levels significantly decreased in group A compared to group B. There was a reduction in the duration of the hospital stay in group A compared to group B. The only observed complication in the groups was hyperthermia, which was not significantly different between the two groups.

CONCLUSION

The present study examined the efficacy and tolerability of phototherapy with reflectors in comparison to conventional phototherapy and found that phototherapy with reflectors was significantly better at controlling bilirubin levels in neonates with indirect hyperbilirubinaemia and at shortening hospitalization time.

Management of late-preterm and term infants with hyperbilirubinaemia in resource-constrained settings

Hyperbilirubinaemia is a ubiquitous transitional morbidity in the vast majority of newborns and a leading cause of hospitalisation in the first week of life worldwide. While timely and effective phototherapy and exchange transfusion are well proven treatments for severe neonatal hyperbilirubinaemia, inappropriate or ineffective treatment of hyperbilirubinaemia, at secondary and tertiary hospitals, still prevails in many poorly-resourced countries accounting for a disproportionately high burden of bilirubin-induced mortality and long-term morbidity. As part of the efforts to curtail the widely reported risks of frequent but avoidable bilirubin-induced neurologic dysfunction (acute bilirubin encephalopathy (ABE) and kernicterus) in low and middle-income countries (LMICs) with significant resource constraints, this article presents a practical framework for the management of late-preterm and term infants (≥ 35 weeks of gestation) with clinically significant hyperbilirubinaemia in these countries particularly where local practice guidelines are lacking. Standard and validated protocols were followed in adapting available evidence-based national guidelines on the management of hyperbilirubinaemia through a collaboration among clinicians and experts on newborn jaundice from different world regions. Tasks and resources required for the comprehensive management of infants with or at risk of severe hyperbilirubinaemia at all levels of healthcare delivery are proposed, covering primary prevention, early detection, diagnosis, monitoring, treatment, and follow-up. Additionally, actionable treatment or referral levels for phototherapy and exchange transfusion are proposed within the context of several confounding factors such as widespread exclusive breastfeeding, infections, blood group incompatibilities and G6PD deficiency, which place infants at high risk of severe hyperbilirubinaemia and bilirubin-induced neurologic dysfunction in LMICs, as well as the limited facilities for clinical investigations and inconsistent functionality of available phototherapy devices. The need to adjust these levels as appropriate depending on the available facilities in each clinical setting and the risk profile of the infant is emphasised with a view to avoiding over-treatment or under-treatment. These recommendations should serve as a valuable reference material for health workers, guide the development of contextually-relevant national guidelines in each LMIC, as well as facilitate effective advocacy and mobilisation of requisite resources for the optimal care of infants with hyperbilirubinaemia at all levels.

Risk factors for severe neonatal hyperbilirubinemia in low and middle-income countries: a systematic review and meta-analysis

BACKGROUND

Available evidence suggests that low- and middle-income countries (LMICs) bear the greatest burden of severe neonatal hyperbilirubinemia characterized by disproportionately high rates of morbidity, mortality and neurodevelopmental disorders compared to high-income countries. We set out to identify the risk factors that contribute to the burden of severe hyperbilirubinemia in the most developmentally disadvantaged LMICs to highlight areas for action and further research.

METHODS

We systematically searched PubMed, Scopus, Ovid EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), WHO Library Database (WHOLIS), African Index Medicus (AIM), African Journals Online (AJOL), LILACS, and IndMed for reports published between January 1990 and June 2014. We included only studies that controlled for the effects of confounding variables in determining maternal and infant risk factors for severe hyperbilirubinemia. We conducted meta-analysis of the eligible studies and computed the summary risk estimates with random effects models.

RESULTS

A total of 13 studies with 1,951 subjects and 32,208 controls from India, Nigeria, Pakistan, Nepal and Egypt were identified and analyzed. The pooled data showed that primiparity (OR, 1.59; 95% CI:1.26-2.00), delivery outside public hospitals (OR, 6.42; 95% CI:1.76-23.36), ABO incompatibility (OR, 4.01; 95% CI:2.44-6.61), Rhesus hemolytic disease (OR, 20.63; 95% CI:3.95-107.65), G6PD deficiency (OR, 8.01; 95% CI:2.09-30.69), UGT1A1 polymorphisms (OR, 4.92; 95% CI:1.30-18.62), low gestational age (OR, 1.71; 95% CI:1.40-2.11), underweight/weight loss (OR, 6.26; 95% CI:1.23-31.86), sepsis (OR, 9.15; 95% CI:2.78-30.10) and high transcutaneous/total serum bilirubin levels (OR, 1.46; 95% CI:1.10-1.92) placed infants at increased risk of severe hyperbilirubinemia or bilirubin induced neurologic dysfunctions. Low social class was not associated with an increased risk of severe hyperbilirubinemia.

CONCLUSIONS

Infants at risk of severe hyperbilirubinemia in LMICs are associated with maternal and neonatal factors that can be effectively addressed by available interventions to curtail the disease burden prevailing in the affected countries.

Addressing the burden of neonatal hyperbilirubinaemia in countries with significant glucose-6-phosphate dehydrogenase deficiency

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an established worldwide risk factor for severe hyperbilirubinaemia. This literature review examined the pattern and management of severe hyperbilirubinaemia in low- and middle-income countries (LMICs) where G6PD deficiency was 10% or more and found that it was frequently associated with neonatal mortality and, or, neurodevelopmental disorders.

CONCLUSION

Low- and middle-income countries need to pay urgent attention to G6PD deficiency to curtail the preventable burden of jaundice-related morbidity, mortality and disability.

Treatment of infections in young infants in low- and middle-income countries: a systematic review and meta-analysis of frontline health worker diagnosis and antibiotic access

BACKGROUND

Inadequate illness recognition and access to antibiotics contribute to high case fatality from infections in young infants (<2 months) in low- and middle-income countries (LMICs). We aimed to address three questions regarding access to treatment for young infant infections in LMICs: (1) Can frontline health workers accurately diagnose possible bacterial infection (pBI)?; (2) How available and affordable are antibiotics?; (3) How often are antibiotics procured without a prescription?

METHODS AND FINDINGS

We searched PubMed, Embase, WHO/Health Action International (HAI), databases, service provision assessments (SPAs), Demographic and Health Surveys, Multiple Indicator Cluster Surveys, and grey literature with no date restriction until May 2014. Data were identified from 37 published studies, 46 HAI national surveys, and eight SPAs. For study question 1, meta-analysis showed that clinical sign-based algorithms predicted bacterial infection in young infants with high sensitivity (87%, 95% CI 82%-91%) and lower specificity (62%, 95% CI 48%-75%) (six studies, n = 14,254). Frontline health workers diagnosed pBI in young infants with an average sensitivity of 82% (95% CI 76%-88%) and specificity of 69% (95% CI 54%-83%) (eight studies, n = 11,857) compared to physicians. For question 2, first-line injectable agents (ampicillin, gentamicin, and penicillin) had low variable availability in first-level health facilities in Africa and South Asia. Oral amoxicillin and cotrimoxazole were widely available at low cost in most regions. For question 3, no studies on young infants were identified, however 25% of pediatric antibiotic purchases in LMICs were obtained without a prescription (11 studies, 95% CI 18%-34%), with lower rates among infants <1 year. Study limitations included potential selection bias and lack of neonatal-specific data.

CONCLUSIONS

Trained frontline health workers may screen for pBI in young infants with relatively high sensitivity and lower specificity. Availability of first-line injectable antibiotics appears low in many health facilities in Africa and Asia. Improved data and advocacy are needed to increase the availability and appropriate utilization of antibiotics for young infant infections in LMICs.

Bacterial meningitis in Malawian infants <2 months of age: etiology and susceptibility to World Health Organization first-line antibiotics

BACKGROUND

Neonatal meningitis is an important cause of morbidity in sub-Saharan Africa and requires urgent empiric treatment with parenteral administered antibiotics. Here we describe the etiology, antimicrobial susceptibility and suitability of the World Health Organization first-line recommended antibiotics (penicillin and gentamicin) for bacterial meningitis in young infants in Malawi.

METHODS

We reviewed all cerebrospinal fluid samples received from infants ≤2 months of age with clinically suspected meningitis between January 1, 2002, and December 31, 2008, at the Queen Elizabeth Central Hospital in Blantyre, Malawi.

RESULTS

We identified 259 culture-positive isolates from 259 infants ≤2 months of age. Sixty isolates were from neonates ≤7 days old, in whom the most common pathogens were Group B Streptococcus (27/60; 45.0%), Streptococcus pneumoniae (13/60; 21.7%) and nontyphoidal Salmonella enterica (7/60; 11.7%). One hundred and ninety one isolates were from young infants who were >7 days and ≤2 months of age. In this group, the most common isolates were S. pneumoniae (80/191; 41.9%), Group B Streptococcus (38/191; 19.9%) and nontyphoidal Salmonella enterica (34/191; 17.8%). More isolates were susceptible to ceftriaxone than to the combination of penicillin and gentamicin (218/220; 99.1% vs. 202/220; 91.8%, Fisher's exact test P = 0.006). In particular, Gram-negative isolates were significantly more susceptible to ceftriaxone than to gentamicin (72/74; 97.3% vs. 63/74; 85.1%, Fisher's exact test P = 0.020). Penicillin and gentamicin provided less coverage for Gram-negative than Gram-positive isolates (74/86; 86.0% vs. 155/163; 95.1%, χ = 6.24, P = 0.012).

CONCLUSIONS

In view of these results, the World Health Organization recommendations for empiric penicillin and gentamicin for suspected neonatal meningitis should be reevaluated.

Pattern and predictors of maternal care-seeking practices for severe neonatal jaundice in Nigeria: a multi-centre survey

BACKGROUND

Nigeria is frequently associated with disproportionately high rates of severe neonatal jaundice (NNJ) underpinned by widespread Glucose-6-phosphate dehydrogenase (G6PD) deficiency. Timely and appropriate treatment of NNJ is crucial for preventing the associated morbidity and neuro-developmental sequelae. Since mothers are likely to be the first mostly to observe the onset of severe illness in their newborns, we set out to identify the pattern and predictors of maternal care-seeking practices for NNJ in three culturally-distinct settings in Nigeria.

METHODS

A multi-centre study was conducted among women attending antenatal clinics in Abuja, Lagos and Port Harcourt from October 2011 to April 2012 using a pretested questionnaire. Predictors of awareness of NNJ, accurate recognition of NNJ, use of potentially harmful therapies and preference for future hospital treatment were determined with multivariate logistic regressions.

RESULTS

Of the 488 participants drawn from the three locations, 431 (88.3%) reported awareness of NNJ, predominantly (57.8%) attributable to professional health workers. A total of 309 (63.3%) mothers with prior knowledge of NNJ claimed they could recognise NNJ, but 270 (87.4%) from this group accurately identified the features of NNJ. Multiparous mothers (Adjusted odds ratio, AOR:4.05; 95% CI:1.75-9.36), those with tertiary education (AOR:1.91; CI:1.01-3.61), and those residing in Lagos (AOR:2.96; CI:1.10-7.97) were more likely to have had prior knowledge of NNJ. Similarly, multiparous mothers (AOR:2.38; CI:1.27-4.46) and those with tertiary education (AOR:1.92; CI:1.21-3.05) were more likely to recognise an infant with jaundice accurately. Mothers educated by health workers were 40% less likely to resort to potentially harmful treatment for NNJ (AOR:0.60; CI:0.39-0.92) but more likely to seek hospital treatment in future for an infant suspected with jaundice (AOR:1.88; CI:1.20-2.95).

CONCLUSIONS

Women with tertiary education and multiparous mothers who attend routine antenatal clinics are more likely than less educated women, to be associated with appropriate care-seeking practices for infants with NNJ regardless of the socio-cultural setting. Systematic efforts by professional health workers are warranted, as part of routine antenatal care, to engage other groups of mothers especially those likely to indulge in self-use of potentially harmful therapies.

Treatment of neonatal jaundice with filtered sunlight in Nigerian neonates: study protocol of a non-inferiority, randomized controlled trial

Background

Severe neonatal jaundice and its progression to kernicterus is a leading cause of death and disability among newborns in poorly-resourced countries, particularly in sub-Saharan Africa. The standard treatment for jaundice using conventional phototherapy (CPT) with electric artificial blue light sources is often hampered by the lack of (functional) CPT devices due either to financial constraints or erratic electrical power. In an attempt to make phototherapy (PT) more readily available for the treatment of pathologic jaundice in underserved tropical regions, we set out to test the hypothesis that filtered sunlight phototherapy (FS-PT), in which potentially harmful ultraviolet and infrared rays are appropriately screened, will be as efficacious as CPT.

Methods/design

This prospective, non-blinded randomized controlled non-inferiority trial seeks to enroll infants with elevated total serum/plasma bilirubin (TSB, defined as 3 mg/dl below the level recommended by the American Academy of Pediatrics for high-risk infants requiring PT) who will be randomly and equally assigned to receive FS-PT or CPT for a total of 616 days at an inner-city maternity hospital in Lagos, Nigeria. Two FS-PT canopies with pre-tested films will be used. One canopy with a film that transmits roughly 33% blue light (wavelength range: 400 to 520 nm) will be used during sunny periods of a day. Another canopy with a film that transmits about 79% blue light will be used during overcast periods of the day. The infants will be moved from one canopy to the other as needed during the day with the goal of keeping the blue light irradiance level above 8 μW/cm²/nm.

Primary outcome: FS-PT will be as efficacious as CPT in reducing the rate of rise in bilirubin levels. Secondary outcome: The number of infants requiring exchange transfusion under FS-PT will not be more than those under CPT.

Conclusion

This novel study offers the prospect of an effective treatment for infants at risk of severe neonatal jaundice and avoidable exchange transfusion in poorly-resourced settings without access to (reliable) CPT in the tropics.

A three year descriptive study of early onset neonatal sepsis in a refugee population on the Thailand Myanmar border

BACKGROUND

Each year an estimated four million neonates die, the majority in the first week of life. One of the major causes of death is sepsis. Proving the incidence and aetiology of neonatal sepsis is difficult, particularly in resource poor settings where the majority of the deaths occur.

METHODS

We conducted a three year observational study of clinically diagnosed early onset (<7 days of age) neonatal sepsis (EONS) in infants born to mothers following antenatal care at the Shoklo Malaria Research Unit clinic in Maela camp for displaced persons on the Thailand-Myanmar border. Episodes of EONS were identified using a clinical case definition. Conventional and molecular microbiological techniques were employed in order to determine underlying aetiology.

RESULTS

From April 2009 until April 2012, 187 infants had clinical signs of EONS, giving an incidence rate of 44.8 per 1000 live births (95% CI 38.7-51.5). One blood culture was positive for Escherichia coli, E. coli was detected in the cerebrospinal fluid specimen in this infant, and in an additional two infants, by PCR. Therefore, the incidence of bacteriologically proven EONS was 0.7 per 1000 live births (95% CI 0.1-2.1). No infants enrolled in study died as a direct result of EONS.

CONCLUSION

A low incidence of bacteriologically proven EONS was seen in this study, despite a high incidence of clinically diagnosed EONS. The use of molecular diagnostics and nonspecific markers of infection need to be studied in resource poor settings to improve the diagnosis of EONS and rationalise antibiotic use.

Full-term newborns with normal birth weight requiring special care in a resource-constrained setting

INTRODUCTION

The level of clinical care and facilities to support the often more viable full-term newborns with normal birth weight compared with preterm/low birth weight newborns that require special care at birth are likely to be attainable in many resource-poor settings. However, the nature of the required care is not evident in current literature. This study therefore set out to determine maternal and perinatal profile of surviving full-term newborns with normal birth weight in a poorly-resourced setting.

METHODS

A retrospective cohort study of newborns with gestational age ≥37 weeks and birth weight ≥2500g recruited in an inner-city maternity hospital in Lagos, Nigeria. Primary factors/outcomes were determined by multivariate logistic regression analyses and population attributable risk (PAR).

RESULTS

Of the 2687 full-term newborns with normal birth weight studied, 242 (9.0%) were admitted into special care baby unit (SCBU) representing 53.6% of all SCBU admissions. Fetal distress, low 5-minute Apgar scores, neonatal sepsis and hyperbilirubinemia as well as maternal factors such as primiparity, type of employment, lack of antenatal care and emergency cesarean delivery were predictive of SCBU admission. The leading contributors to SCBU admission were neonatal sepsis (PAR=96.8%), and hyperbilirubinemia (PAR=58.7%).

CONCLUSION

A significant proportion of newborns requiring special care are full-term with normal birth weight and are associated with modifiable risk factors that can be effectively addressed at appropriately equipped secondary-level hospitals. Prenatal maternal education on avoidable risk factors is warranted.

Trends in incidence of neonatal sepsis and antibiotic susceptibility of causative agents in two neonatal intensive care units in tehran, I.R iran

BACKGROUND

Neonatal sepsis is a worldwide problem that presents a management challenge to care groups for neonates and infants. Early diagnosis and management can considerably decrease the risk of sepsis, and improve the outcome.

AIM

The aim of the present study was to determine the incidence, causative pathogens, and the antibiotic sensitivity pattern for neonatal sepsis in Iran.

MATERIALS AND METHODS

A historical cohort study was conducted on 84 patients with neonatal sepsis who were admitted to the neonatal intensive care unit (NICU) wards of Baqiyatallah and Najmieh University hospitals in Tehran, between 2003 and 2006. Clinical, demographic and laboratory data was collected from medical records.

RESULTS

Among all the comprised neonates, 44 patients were diagnosed with early-onset sepsis, 23 cases with late-onset sepsis and others with nosocomial sepsis. The most common isolated pathogen in all groups was Enterobacter, and was responsible for 31.4%, 47.8% and 41.2% of the episodes of sepsis, according to the sepsis type mentioned above, respectively. Susceptibility of common sepsis related pathogens to imipenem and gentamycin gradually reduced over the years between 2003 and 2006. Total mortality and morbidity rates due to neonatal sepsis were estimated at 27.4% and 89.3%, respectively. Mortality following sepsis was found more in boys (Odds Ratio (OR)=4.897, Conifdence Interval (CI)=95%, P=0.031), and those with low birth weight (OR=4.406, CI: 95%, P=0.011). Higher sepsis related co-morbidity was found in neonates following cesarean delivery (OR=6.280, CI: 95%, P=0.025).

CONCLUSION

It seems that the mortality rate in this study was lower than similar studies in Iran and other developing countries. This difference between the mortality rates of the centers in our study and others could be due to the high occurrence of Enterobacter infections in the latter and also high resistance of these pathogens to commonly used antibiotics such as β-lactams and aminoglycosides reported in other studies.

The performance of children prenatally exposed to HIV on the A-not-B task in Kilifi, Kenya: a preliminary study

The aim of the study was to investigate early executive functioning in young children from 6–35 months of age. The study involved 319 randomly selected children from the community, 17 HIV exposed but uninfected children and 31 HIV infected ARV-naive children. A variation of the A-not-B task was used. While there were no group differences in total correct, perseverative errors, nor maximum error run, a significant percentage of children were unable to complete the task as a consequence of the children becoming overtly distressed or refusing to continue. In a multivariate analysis we observed that the significant predictors of non-completion were HIV exposure (both infected and exposed) and being under 24 months of age. These patterns of results indicate that future work with a broader array of tasks need to look at the association of HIV and EF tasks and potential contribution of factors such as emotion regulation, persistence and motivation on performance on EF tasks.

Phototherapy device effectiveness in Nigeria: irradiance assessment and potential for improvement

This study investigated the effectiveness of simple-to-implement adjustments of phototherapy devices on irradiance levels in a cross-section of Nigerian hospitals. A total of 76 phototherapy devices were evaluated in 16 hospitals while adjustments were implemented for a subset of 25 devices for which consent was obtained. The mean irradiance level was 7.6 ± 5.9 µW/cm(2)/nm for all devices prior to adjustments. The average irradiance level improved from 9.0 µW/cm(2)/nm to 27.3 µW/cm(2)/nm for the adjusted group (n = 25) compared with 6.8 ± 5.4 µW/cm(2)/nm for the unadjusted group (n = 51). Simple, inexpensive adjustments to phototherapy devices with sub-optimal irradiance levels can significantly improve their effectiveness to acceptable international standards and should be widely promoted in resource-constrained settings.

Changes in the body weight of term infants, born in the tropics, during the first seven days of life

BACKGROUND

Identifying unwell neonates, particularly in the first week of life, is often subjective. If normal values are known, calculating the weight lost or gained from birth weight can be a useful adjunct in the evaluation of the health of a neonate.

METHODS

Serial body weights of well, term, breast fed infants who were attending for routine follow up, were recorded at the Shoklo Malaria Research Unit clinic in Maela Camp for displaced persons on the Thailand Myanmar border. Newborn examination was routine. Weight loss, expressed as percent weight lost from birth weight, and weight gain, expressed as a velocity (g/kg/day), was calculated for the first seven days of life. The results from normal birth weight infants, low birth weight infants (<2.5 kg) and small for gestational age infants (SGA) were examined.

RESULTS

In the first week of life there were no significant differences in weight gained or lost across the three study groups. The maximum weight lost was 4.4% (95% CI 4.1 - 4.6%), which occurred on day three. Weight gain ranged from 13 g/kg/day [95% CI 10 - 16] on day four to 18 g/kg/day [95% CI 15 - 20] on days six and seven.

CONCLUSIONS

Use of these normal values for weight gain and loss, allows infants falling outside of the expected range (95% CI) to be easily identified and subsequently highlighted as needing further medical review.

Future challenges in the elimination of bacterial meningitis

Despite the widespread implementation of several effective vaccines over the past few decades, bacterial meningitis caused by Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis and Group B Streptococcus (GBS) still results in unacceptably high levels of human mortality and morbidity. A residual disease burden due to bacterial meningitis is also apparent due to a number of persistent or emerging pathogens, including Mycobacterium tuberculosis, Escherichia coli, Staphylococcus aureus, Salmonella spp. and Streptococcus suis. Here, we review the current status of bacterial meningitis caused by these pathogens, highlighting how past and present vaccination programs have attempted to counter these pathogens. We discuss how improved pathogen surveillance, implementation of current vaccines, and development of novel vaccines may be expected to further reduce bacterial meningitis and related diseases in the future.

Paediatricians' perspectives on global health priorities for newborn care in a developing country: a national survey from Nigeria

BACKGROUND

An understanding of the perception of paediatricians as key stakeholders in child healthcare delivery and the degree of congruence with current investment priorities is crucial in accelerating progress towards the attainment of global targets for child survival and overall health in developing countries. This study therefore elicited the views of paediatricians on current global priorities for newborn health in Nigeria as possible guide for policy makers.

METHODS

Paediatric consultants and residents in the country were surveyed nationally between February and March 2011 using a questionnaire requiring the ranking of nine prominent and other neonatal conditions based separately on hospital admissions, mortality, morbidity and disability as well as based on all health indices in order of importance or disease burden. Responses were analysed with Friedman test and differences between subgroups of respondents with Mann-Whitney U test.

RESULTS

Valid responses were received from 152 (65.8%) of 231 eligible physicians. Preterm birth/low birthweight ranked highest by all measures except for birth asphyxia which ranked highest for disability. Neonatal jaundice ranked next to sepsis by all measures except for disability and above tetanus except mortality. Preterm birth/low birthweight, birth asphyxia, sepsis, jaundice and meningitis ranked highest by composite measures while jaundice had comparable rating with sepsis. Birth trauma was most frequently cited under other unspecified conditions. There were no significant differences in ranking between consultants and residents except for birth asphyxia in relation to hospital admissions and morbidity as well as sepsis and tetanus in relation to mortality.

CONCLUSIONS

Current global priorities for neonatal survival in Nigeria largely accord with paediatricians' views except for neonatal jaundice which is commonly subsumed under "other" or "miscellaneous" neonatal conditions. While the importance of these priority conditions extends beyond mortality thus suggesting the need for a broader conceptualisation of newborn health to reflect the current realities, paediatricians should be actively engaged in advancing the attainment of global priorities for child survival and health in this population.
