The Impact of Recycled Neonatal Incubators in Nigeria: A 6-Year Follow-Up Study
Nigeria has a record of high newborn mortality as an estimated 778 babies die daily, accounting for a ratio of 48 deaths per 1000 live births. The aim of this paper was to show how a deteriorating neonatal delivery system in Nigeria may have, in part, been improved by the application of a novel recycled incubator technique (RIT). Retrospective assessment of clinical, technical, and human factors in 15 Nigerian neonatal centres was carried out to investigate how the application of RIT impacted these factors. Pre-RIT and post-RIT neonatal mortalities were compared by studying case files. Effect on neonatal nursing was studied through questionnaires that were completed by 79 nurses from 9 centres across the country. Technical performance was assessed based on 10-indices scores from clinicians and nurses. The results showed an increase in neonatal survival, nursing enthusiasm, and practice confidence. Appropriately recycled incubators are good substitutes to the less affordable modern incubators in boosting neonatal practice outcome in low-income countries
Pediatric Bacterial Meningitis Surveillance in Nigeria From 2010 to 2016, Prior to and During the Phased Introduction of the 10-Valent Pneumococcal Conjugate Vaccine.
BACKGROUND: Historically, Nigeria has experienced large bacterial meningitis outbreaks with high mortality in children. Streptococcus pneumoniae (pneumococcus), Neisseria meningitidis (meningococcus), and Haemophilus influenzae are major causes of this invasive disease. In collaboration with the World Health Organization, we conducted longitudinal surveillance in sentinel hospitals within Nigeria to establish the burden of pediatric bacterial meningitis (PBM). METHODS: From 2010 to 2016, cerebrospinal fluid was collected from children <5 years of age, admitted to 5 sentinel hospitals in 5 Nigerian states. Microbiological and latex agglutination techniques were performed to detect the presence of pneumococcus, meningococcus, and H. influenzae. Species-specific polymerase chain reaction and serotyping/grouping were conducted to determine specific causative agents of PBM. RESULTS: A total of 5134 children with suspected meningitis were enrolled at the participating hospitals; of these 153 (2.9%) were confirmed PBM cases. The mortality rate for those infected was 15.0% (23/153). The dominant pathogen was pneumococcus (46.4%: 71/153) followed by meningococcus (34.6%: 53/153) and H. influenzae (19.0%: 29/153). Nearly half the pneumococcal meningitis cases successfully serotyped (46.4%: 13/28) were caused by serotypes that are included in the 10-valent pneumococcal conjugate vaccine. The most prevalent meningococcal and H. influenzae strains were serogroup W and serotype b, respectively. CONCLUSIONS: Vaccine-type bacterial meningitis continues to be common among children <5 years in Nigeria. Challenges with vaccine introduction and coverage may explain some of these finding. Continued surveillance is needed to determine the distribution of serotypes/groups of meningeal pathogens across Nigeria and help inform and sustain vaccination policies in the country
Effects of diet containing monosodium glutamate on organ weights, acute blood steroidal sex hor mone levels, lipid profile and er ythrocyte antioxidant enzymes activities of rats
Objective: To study the effects of diet containing monosodium glutamate on visceral
organ weights, acute blood steroidal sex hormone levels, serum lipid profile (SLP) and
erythrocyte antioxidant enzymes activities of Wistar rats.
Methods: The Wistar rats were grouped into two groups of six rats each. The ones in
Group 1 (control group) were placed on water and pelletized standard guinea feed ad
libitum, whereas Group 2 was regarded as test group [Wistar rats (WR)-monosodium
glutamate (MSG) group] and the Wistar rats received water, compounded diet of MSG
and pelletized standard guinea feed ad libitum. After 33 days of feeding study, rat body
weight was obtained. Rats were sacrificed and the incisions were made into the thoracic
cavity and blood samples were drawn by cardiac puncture as a terminal event. Plasma
was assayed for estradiol and testosterone concentrations, SLP and erythrocyte peroxidase and catalase activities. Visceral organ weights were also measured.
Results: WR-MSG exhibited marginal alterations in blood estradiol and testosterone concentrations. Elevation of serum triacylglycerol concentration in WR-MSG was corresponded
to 77.7%. Increases in serum concentrations of very low-density lipoprotein cholesterol and
low-density lipoprotein cholesterol in WR-MSG were corresponded to 70.6% and 41.0%
respectively. Erythrocyte peroxidase and catalase activities showed marginal alterations.
Alterations in visceral organs-to-body weights ratios were not profound.
Conclusions: Blood testosterone and estradiol concentrations were not significantly
(P > 0.05) altered, which may not be connected with the low dose of MSG in the diet.
Marginal alterations of SLP did not indicate atherogenicity in WR-MSG. The visceral
organs were not atrophic or hypertrophic because of the comparatively low dose of MSG
consumed by WR-MSG and the duration of the feeding experiment
