Prevalence of Hearing Impairment Among High-Risk Newborns in Ibadan, Nigeria
The burden of severe hearing impairment is increasing with two-thirds of these hearing impaired people residing in developing countries. Newborn hearing screening helps to identify early, babies who need intervention in order to prevent future disability. Neither universal nor targeted hearing screening programme is available in Nigeria.Objectives: This study was carried out to assess the prevalence of hearing impairment among high-risk newborns in UCH and the associated risk factors.Materials and Methods: Two hundred one newborns in the neonatal unit of UCH with risk factors for hearing impairment had hearing screening done using automated auditory brainstem response (AABR) at 30, 45, and 70 dB at admission and discharge, and those that failed screening at discharge were rescreened at 6 weeks post-discharge.Results: Eighty-three (41.3%) and 32 (15.9%) high-risk newborns failed at admission and discharge screening respectively, and 19 (9.5%) still failed at follow up screening. The majority of hearing loss at follow up was bilateral (94.7%) and severe (52.6%). The risk factors associated with persistent hearing loss at follow up were acute bilirubin encephalopathy (RR = 11.2, CI: 1.4–90.6), IVH (RR = 8.8, CI: 1.1–71.8), meningitis (RR = 4.8, CI: 1.01–29), recurrent apnoea (RR = 2.7, CI: 1.01–7.3), severe perinatal asphyxia NNE III (RR = 7, CI: 2.4–20.2).Conclusion: Severe and bilateral hearing impairment is a common complication among high risk newborns in UCH persisting till 6 weeks post-neonatal care. Severe perinatal asphyxia with NNE III, ABE, IVH, meningitis and administration of amikacin for more than 5 days were significant risk factors. We recommend that SCBU graduates with these risk factors should have mandatory audiologic evaluation at discharge
Detection of fever in children emergency care: comparisons of tactile and rectal temperatures in Nigerian children
<p>Abstract</p> <p>Background</p> <p>Clinical thermometry is the objective method for temperature measurements but tactile assessment of fever at home is usually the basis for seeking medical attention especially where the cost and level of literacy preclude the use of thermometers. This study was carried out to determine the reliability of tactile perception of fever by caregivers, nurses and house physicians in comparison to rectal thermometry and also the use of commonly practiced surface of the hand in the care of ill children. All caregivers of children aged 6 to 59 months who presented to the emergency department were approached consecutively at the triage stage but 182 children participated. Each child had tactile assessment of fever using palmar and dorsal surfaces of the hand by the caregivers, House Physicians and Nursing Officers. Rectal temperature was also measured and read independently by nurses and house physicians. Comparisons were made between tactile assessments and thermometer readings using a cut-off for fever, 38.0°C and above.</p> <p>Findings</p> <p>The caregivers' perception of fever had a sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 95%, 23%, 66% and 73%, respectively compared with 93%, 26%, 67% and 69%, respectively for nursing officers. Irrespective of the groups studied, 77.1% of 336 assessors opined that the dorsal surface of the hand was more sensitive in tactile assessment of temperature and the frequently used site for assessment of fever were the head (35.6%) and neck (33.3%). Tactile assessment of temperature over-detected fever in ≥ 24% of cases among the three groups of assessors.</p> <p>Conclusions</p> <p>The present study suggests that tactile assessment of temperature may over estimate the prevalence of fever, it does not detect some cases and the need for objective measurement of temperature is emphasised in paediatric emergency care.</p
Aetiology of neonatal jaundice in apparently well late-preterm and term neonates at a mission hospital, Southwestern Nigeria
Background: The knowledge of the aetiology for neonatal jaundice is important in the early detection and effective management of infants with or at risk of severe jaundice before hospital discharge. This study assessed the aetiological factors of neonatal jaundice among apparently well late preterm and termnewborns to ensure timely intervention where these risk factors exist.Method: This was a cross sectional study involving 174 apparently well neonates at a tertiary mission hospital. Detailed history, physical examination, relevant haematological and biochemical tests were undertaken. Significant jaundice was defined as serum bilirubin greater than 2 standard deviations above the postnatal age and weight dependent treatment concentration.Results: Of the 844 neonates admitted into the neonatal care unit, 174 (20.6%) had significant jaundice. Median age at presentation was 3 days (95% CI of median 3-4days). The mean ±SD gestation age and birth weight of the neonates at recruitment were 38.1±1.6 weeks and 3.1± 0.5kg respectively. Males were 108 (62.4%; M: F.1.6.1). The mean ±SD total serum bilirubin was 13.9±4.7mg/dl. Significant jaundice was more common with maternal-baby concordant paired blood group of AA, O-O compared with discordant materno-baby group pairs. Of the known causes of significant neonatal jaundice, G6PD deficiency (57-38.5%) ranked topmost. Half (87-50.0%) of the causes of significant jaundice were unidentified.Conclusion : G6PD deficiency remains the leading aetiology for significant neonatal jaundice. G6PD screening should be mandated before hospital discharge, compatible mother-baby blood group pairs do not rule the risk for significant jaundice; further research is required to elucidate other inherent unidentified aetiologies
Intestinal Bacterial Colonization in the First 2 Weeks of Life of Nigerian Neonates Using Standard Culture Methods
Time to full enteral feeds in hospitalised preterm and very low birth weight infants in Nigeria and Kenya
Background: Preterm (born \u3c 37 weeks’ gestation) and very low birthweight (VLBW; \u3c1.5kg) infants are at the greatest risk of morbidity and mortality within the first 28 days of life. Establishing full enteral feeds is a vital aspect of their clinical care. Evidence predominantly from high income countries shows that early and rapid advancement of feeds is safe and reduces length of hospital stay and adverse health outcomes. However, there are limited data on feeding practices and factors that influence the attainment of full enteral feeds among these vulnera- ble infants in sub-Saharan Africa.
Aim: To identify factors that influence the time to full enteral feeds, defined as tolerance of 120ml/ kg/day, in hospitalised preterm and VLBW infants in neonatal units in two sub-Saharan Afri- can countries.
Methods: Demographic and clinical variables were collected for newborns admitted to 7 neonatal units in Nigeria and Kenya over 6-months. Multiple linear regression analysis was conducted to identify factors independently associated with time to full enteral feeds.
Results: Of the 2280 newborn infants admitted, 484 were preterm and VLBW. Overall, 222/484 (45.8%) infants died with over half of the deaths (136/222; 61.7%) occurring before the first feed. The median (inter-quartile range) time to first feed was 46 (27, 72) hours of life and time to full enteral feeds (tFEF) was 8 (4.5,12) days with marked variation between neonatal units. Independent predictors of tFEF were time to first feed (unstandardised coefficient B 1.69; 95% CI 1.11 to 2.26; p value \u3c0.001), gestational age (1.77; 0.72 to 2.81; \u3c0.001), the occurrence of respiratory distress (-1.89; -3.50 to -0.79; \u3c0.002) and necrotising enterocoli- tis (4.31; 1.00 to 7.62; \u3c0.011).
Conclusion: The use of standardised feeding guidelines may decrease variations in clinical practice, shorten tFEF and thereby improve preterm and VLBW outcome
Utilisation of malaria preventive measures during pregnancy and birth outcomes in Ibadan, Nigeria
<p>Abstract</p> <p>Background</p> <p>Malaria remains a major public health problem in sub Saharan Africa and the extent of utilisation of malaria preventive measures may impact on the burden of malaria in pregnancy. This study sought to determine the association between malaria preventive measures utilized during pregnancy and the birth outcomes of birth weight and preterm delivery.</p> <p>Methods</p> <p>This cross sectional survey involved 800 mothers who delivered at the University College Hospital, and Adeoyo Maternity Hospital, Ibadan. Data obtained included obstetric information, gestational age, birth weight and self reported use of malaria prevention strategies in index pregnancy.</p> <p>Results</p> <p>Most (95.6%) mothers used one or more malaria control measures. The most commonly used vector control measures were window net (84.0%), insecticide spray (71.5%) and insecticide treated bed nets (20.1%), while chemoprophylactic agents were pyrimethamine (23.5%), Intermittent Preventive Treatments with Sulphadoxine-Pyrimethamine (IPTsp) (18.5%) and intermittent chloroquine (9.5%) and 21.7% used herbal medications. The mean ± SD birthweight and gestational age of the babies were 3.02 kg ± 0.56 and 37.9 weeks ± 2.5 respectively. Preterm delivery rate was 19.4% and 9% had low birth weight.</p> <p>Comparing babies whose mothers had IPTsp with those who did not, mean birth weight was 3.13 kg ± 0.52 versus 3.0 kg ± 0.56 (p = 0.016) and mean gestational age was 38.5 weeks ± 2.1 versus 37.8 weeks ± 2.5 (p = 0.002).</p> <p>The non-use of IPTsp was associated with increased risk of having low birth weight babies (AOR: 2.27, 95% CI: 0.98; 5.28) and preterm birth (AOR: 1.93, 95% CI: 1.08, 3.44). The non use of herbal preparations (AOR: 0.55, 95% CI: 0.36, 0.85) was associated with reduced risk of preterm birth. The mean ± SD birth weight and gestational ages of babies born to mothers who slept under ITNs were not significantly different from those who did not (p = 0.07 and 0.09 respectively).</p> <p>Conclusions</p> <p>There is a need for improved utilisation of IPTsp as well as discouraging the use of herbal medications in pregnancy in order to reduce pregnancy outcome measures of low birth weight and preterm deliveries in this environment.</p
Parents' perceptions of core outcomes in neonatal research in two Nigerian neonatal units.
Background:There is a scarcity of information regarding the most important outcomes for research in neonatal units in low-resource settings. Identification of important outcomes by different stakeholder groups would inform the development of a core outcome set (COS) for use in neonatal research. Objective:To determine the perceptions and opinions of parents of newborn babies regarding what outcomes were most important to them in order to contribute towards development of a COS for neonatal research in sub-Saharan Africa. Methods:Semistructured interviews were undertaken with parents, mostly mothers, of babies admitted to one neonatal unit in North central and one in Southwest Nigeria. Participants were purposively sampled to include parents of babies with common neonatal problems such as prematurity. Results:We conducted 31 interviews. The most frequently raised outcomes were breast feeding, good health outcomes for their baby, education, growth and financial cost. Parents placed more emphasis on quality of life and functional status than health complications. Conclusions:The opinions of parents need to be considered in developing a COS for neonatal research in low-resource settings. Further research should assess the opinions of families in other low-resource settings and also engage a broader range of stakeholders
Newborn resuscitation practices and paucity of resuscitative devices in Nigeria; a call to action
Background: Neonatal resuscitation is a method of preventing
morbidities & mortality from asphyxia. Up to 85% of facilities in
sub-Saharan Africa lack supplies or skilled personnel for neonatal
resuscitation. Relative to the place of birth and the skill of the
birth attendant, a variety of resuscitative practice are employed to
make babies cry instead of helping the baby breathe. Many painful
procedures are applied when the baby is unable to cry after birth in
the absence of a health care worker trained in bag-mask ventilation.
Objectives: To ascertain the resuscitation practices in communities
lacking bag-mask-valve devices Methods: Surveys on the resuscitation
practices during NISONM annual community outreach and mENCC trainings
for four consecutive years in different geopolitical zones of the
country. Results: Spanking of the baby usually in the upside down
position (>90%), body massage with hot compress or salicylate
containing balms, herbal concoctions, injection hydrocortisone or
crystalline penicillin were used. Conclusion: There is an urgent need
to address the issue of training on bag-mask ventilation and provision
for frontline healthcare workers in Nigeria as a neonatal mortality
reduction strategy. DOI: https://dx.doi.org/10.4314/ahs.v19i1.30 Cite

Time to full enteral feeding for very low-birth-weight infants varies markedly among hospitals worldwide but may not be associated with incidence of necrotizing enterocolitis:The NEOMUNE-NeoNutriNet Cohort Study
Background: Transition to enteral feeding is difficult for very low-birth-weight (VLBW; ≤1500 g) infants, and optimal nutrition is important for clinical outcomes. Method: Data on feeding practices and short-term clinical outcomes (growth, necrotizing enterocolitis [NEC], mortality) in VLBW infants were collected from 13 neonatal intensive care units (NICUs) in 5 continents (n = 2947). Specifically, 5 NICUs in Guangdong province in China (GD), mainly using formula feeding and slow feeding advancement (n = 1366), were compared with the remaining NICUs (non-GD, n = 1581, Oceania, Europe, United States, Taiwan, Africa) using mainly human milk with faster advancement rates. Results: Across NICUs, large differences were observed for time to reach full enteral feeding (TFF; 8–33 days), weight gain (5.0–14.6 g/kg/day), ∆z-scores (−0.54 to −1.64), incidence of NEC (1%–13%), and mortality (1%–18%). Adjusted for gestational age, GD units had longer TFF (26 vs 11 days), lower weight gain (8.7 vs 10.9 g/kg/day), and more days on antibiotics (17 vs 11 days; all P <.001) than non-GD units, but NEC incidence and mortality were similar. Conclusion: Feeding practices for VLBW infants vary markedly around the world. Use of formula and long TFF in South China was associated with more use of antibiotics and slower weight gain, but apparently not with more NEC or higher mortality. Both infant- and hospital-related factors influence feeding practices for preterm infants. Multicenter, randomized controlled trials are required to identify the optimal feeding strategy during the first weeks of life
