Socio - demographic characteristics of HIV patients diagnosed at immunization centres in Calabar, South – south, Calabar, Nigeria

Introduction: The World Health Organization (WHO) estimated that 3.2 million children were living with Human Immunodeficiency Virus (HIV) at the end of 2013, mostly in sub- Saharan Africa. Socio- economic and demographic factors do not only affect viral transmission but also the success of preventive strategies and treatment.Objective: To determine the socio -demographic characteristics of mothers, and the relationship between maternal and HIV status of their infants attending immunization clinics in Calabar.Methods: Using multistage sampling method, 330 subjects were enrolled and screened from 63 immunization centres. The sociodemographic characteristic ofeach infant’s mother was documented. The results of Rapid test for mothers and Dried Blood Spots (DBS) results for infants were compared.Results: Of the 330 subjects recruited, 173 (52.4%) were males while 157(47.6%) were females. Mean age of the infants was 9.20 ± 3.1 weeks. Twenty four mothers and infants tested positive for HIV antibodies. After confirmatory tests using HIV Deoxyribosenucleic acid (DNA PCR), 14(58.3%) out of 24 antibody seropositive infants were infected. The transmission rate after confirmation was 58.3%.Conclusion: Parental education, social class and low maternal Antiretroviral drug (ARV) use were responsible for transmission. It is therefore recommended that health education on ARV use during antenatal period and HIV status of mother baby pair be done at immunization centres. HIV positive mothers and babies should be promptly referred for therapy.Keywords: Immunization, HIV, Infants, DNA PCR, PMTCT, AR

Malariometric indices among Nigerian children in a rural setting

Malaria contributes to high childhood morbidity and mortality in Nigeria. To determine its endemicity in a rural farming community in the south-south of Nigeria, the following malariometric indices, namely, malaria parasitaemia, spleen rates, and anaemia were evaluated in children aged 2-10 years. This was a descriptive cross-sectional survey among school-age children residing in a rubber plantation settlement. The children were selected from six primary schools using a multistaged stratified cluster sampling technique. They were all examined for pallor, enlarged spleen, or liver among other clinical parameters and had blood films for malaria parasites. Of the 461 children recruited, 329 (71.4%) had malaria parasites. The prevalence of malaria parasitaemia was slightly higher in the under fives than that of those ≥5 years, 76.2% and 70.3%, respectively. Splenic enlargement was present in 133 children (28.9%). The overall prevalence of anaemia was 35.7%. Anaemia was more common in the under-fives (48.8%) than in those ≥5 years (32.8%). The odds of anaemia in the under fives were significantly higher than the odds of those ≥5 years (OR = 1.95 [1.19-3.18]). Malaria is highly endemic in this farming community and calls for intensification of control interventions in the area with special attention to school-age children

Birth defects in newborns and stillborns: an example of the Brazilian reality

<p>Abstract</p> <p>Background</p> <p>This study constitutes a clinical and genetic study of all newborn and stillborn infants with birth defects seen in a period of one year in a medical school hospital located in Brazil. The aims of this study were to estimate the incidence, causes and consequences of the defects.</p> <p>Methods</p> <p>For all infants we carried out physical assessment, photographic records, analysis of medical records and collection of additional information with the family, besides the karyotypic analysis or molecular tests in indicated cases.</p> <p>Result</p> <p>The incidence of birth defects was 2.8%. Among them, the etiology was identified in 73.6% (ci95%: 64.4-81.6%). Etiology involving the participation of genetic factors single or associated with environmental factors) was more frequent 94.5%, ci95%: 88.5-98.0%) than those caused exclusively by environmental factors (alcohol in and gestational diabetes mellitus). The conclusive or presumed diagnosis was possible in 85% of the cases. Among them, the isolated congenital heart disease (9.5%) and Down syndrome (9.5%) were the most common, followed by gastroschisis (8.4%), neural tube defects (7.4%) and clubfoot (5.3%). Maternal age, parental consanguinity, exposure to teratogenic agents and family susceptibility were some of the identified risk factors. The most common observed consequences were prolonged hospital stays and death.</p> <p>Conclusions</p> <p>The current incidence of birth defects among newborns and stillbirths of in our population is similar to those obtained by other studies performed in Brazil and in other underdeveloped countries. Birth defects are one of the major causes leading to lost years of potential life. The study of birth defects in underdeveloped countries should continue. The identification of incidence, risk factors and consequences are essential for planning preventive measures and effective treatments.</p

Consanguinity and reproductive health among Arabs

Consanguineous marriages have been practiced since the early existence of modern humans. Until now consanguinity is widely practiced in several global communities with variable rates depending on religion, culture, and geography. Arab populations have a long tradition of consanguinity due to socio-cultural factors. Many Arab countries display some of the highest rates of consanguineous marriages in the world, and specifically first cousin marriages which may reach 25-30% of all marriages. In some countries like Qatar, Yemen, and UAE, consanguinity rates are increasing in the current generation. Research among Arabs and worldwide has indicated that consanguinity could have an effect on some reproductive health parameters such as postnatal mortality and rates of congenital malformations. The association of consanguinity with other reproductive health parameters, such as fertility and fetal wastage, is controversial. The main impact of consanguinity, however, is an increase in the rate of homozygotes for autosomal recessive genetic disorders. Worldwide, known dominant disorders are more numerous than known recessive disorders. However, data on genetic disorders in Arab populations as extracted from the Catalogue of Transmission Genetics in Arabs (CTGA) database indicate a relative abundance of recessive disorders in the region that is clearly associated with the practice of consanguinity

Zinc function in childhood brain

Zinc is essential in the metabolic activities in the body including protein, DNA and RNA synthesis. It plays a role in neurogenesis, maturation, and migration of neurons and in synapse formation. Zinc is high in the hippocampal neurons which is involved in learning and memory. Deficiency of zinc during pregnancy has been related to many congenital abnormalities of the foetal nervous system. Furthermore insufficient levels of zinc in children is associated with lowered learning ability, apathy, lethargy and mental retardation. Maternal deficiency of zinc during lactation has been associated with impairment of infant brain development. Zinc status in mother and child can be assessed by measurement of zinc in plasma; zinc deficiency can be corrected with appropriate diet and zinc supplements. Red meat, poultry items, oysters, cashew nuts and almonds are rich sources of zinc
