Heliotherapy for Neonatal Hyperbilirubinemia in Southwest,Nigeria: A Baseline Pre-Intervention Study
Background
A novel filtered-sunlight phototherapy (FSPT) device has been demonstrated to be safe and efficacious for treating infants with neonatal jaundice in resource-constrained tropical settings. We set out to provide baseline data for evaluating the clinical impact of this device in a referral pediatric hospital.Methods
We reviewed the medical records of infants admitted for neonatal hyperbilirubinemia in an inner-city Children’s Hospital in Lagos, between January 2012 and December 2014 to determine the pattern, treatment and outcomes during the pre-intervention period. Factors associated with adverse outcomes were identified through multivariable logistic regression.Results
Of the 5,229 neonatal admissions over the period, a total of 1,153 (22.1%) were admitted for neonatal hyperbilirubinemia. Complete records for 1,118 infants were available for analysis. The incidence of acute bilirubin encephalopathy (ABE) and exchange transfusion (ET) were 17.0% (95% CI: 14.9%–19.3%) and 31.5% (95% CI: 28.8%–34.3%) respectively. A total of 61 (5.5%, 95% CI: 4.3%–6.9%) of the jaundiced infants died. Weight on admission, peak total serum bilirubin (TSB), sepsis and exposure to hemolytic products were predictive of ABE, while age on admission, peak TSB, ABO incompatibility and ABE were predictive of ET. Rhesus incompatibility, asphyxia, exposure to hemolytic substances and ABE were associated with elevated mortality risk, while ET was a protective factor. Lack of routine irradiance monitoring and steady energy supply were frequent challenges for conventional blue-light phototherapy.Conclusions
Severe hyperbilirubinemia is associated with high rates of ABE and ET in this setting, and remains a significant contributor to neonatal admissions and mortality. To be impactful, FSPT, complemented with improved diagnostic facilities, should effectively curtail jaundice-related adverse outcomes in this and comparable settings. 相似文献2.
Studies on the impact of subclinical hypothyroidism in infertility are scarce and this seeks to determine the proportion of infertile Nigerian women with hyperprolactinaemia that had subclinical hypothyroidism. Serum prolactin and thyroid stimulating hormone were determined using ELECSYS 1010 auto analyzer. Two hundred infertile women were evaluated and 67(33.7%) had hyperprolactinaemia. Subclinical hypothyroidism was observed in 14.9% of women with hyperprolactinaemia, 4.5% and 10.5% of women with primary and secondary infertility, while hyperprolactinaemia was observed in 29.9% and 70.1% in primary and secondary infertility respectively. Mean levels of thyroid stimulating hormone and prolactin were higher in secondary infertility than primary infertility. Subclinical hypothyroidism and hyperprolactinaemia were higher in secondary infertility than primary infertility. The ratio of proportions between hypothyroidism and hyperprolactinaemia was 1:7. Keywords: Sub clinical hypothyroidism, Hyperprolactinaemia, Primary infertility, Secondary infertility. 相似文献

Increasing evidence indicates that neurodegeneration involves the activation of the cell cycle machinery in postmitotic neurons. However, the purpose of these cell cycle-associated events in neuronal apoptosis remains unknown. Here we tested the hypothesis that cell cycle activation is a critical component of the DNA damage response in postmitotic neurons. Different genotoxic compounds (etoposide, methotrexate, and homocysteine) induced apoptosis accompanied by cell cycle reentry of terminally differentiated cortical neurons. In contrast, apoptosis initiated by stimuli that do not target DNA (staurosporine and colchicine) did not initiate cell cycle activation. Suppression of the function of ataxia telangiectasia mutated (ATM), a proximal component of DNA damage-induced cell cycle checkpoint pathways, attenuated both apoptosis and cell cycle reentry triggered by DNA damage but did not change the fate of neurons exposed to staurosporine and colchicine. Our data suggest that cell cycle activation is a critical element of the DNA damage response of postmitotic neurons leading to apoptosis. 相似文献

1. The non-saponifiable fractions (NSF) of the liver lipids of the common Nigerian shark Carcharias taurus were identified by mass-spectrometry. 2. The lipids were extracted from the liver microsomes. 3. Hydrocarbons made up 21.29% of the NSF, sterols 26.45% and coenzymes 52.26%. 4. Thin layer chromatography followed by mass-spectral analysis showed that squalene was the major hydrocarbon present. 5. The sterol fraction consisted of cholesterol, 1-octanol and 1-hexadecyl glycerol ether. 6. The coenzymes consisted clearly of vitamin A, coenzyme Q and probably also vitamin E. 相似文献
