BACKGROUND: Established in 2000, Millennium Development Goal 4 (MDG4) catalysed extraordinary political, financial, and social commitments to reduce under-5 mortality by two-thirds between 1990 and 2015. At the country level, the pace of progress in improving child survival has varied markedly, highlighting a crucial need to further examine potential drivers of accelerated or slowed decreases in child mortality. The Global Burden of Disease 2015 Study (GBD 2015) provides an analytical framework to comprehensively assess these trends for under-5 mortality, age-specific and cause-specific mortality among children under 5 years, and stillbirths by geography over time...

PURPOSE OF REVIEW: The number of HIV-exposed but uninfected (HEU) infants exposed to both HIV and multiple antiretroviral drugs in utero and during prolonged breastfeeding is increasing in low-income countries where HIV prevalence is the highest. We review recent evidence on the effects of perinatal/postnatal exposure to maternal HIV and combined antiretroviral therapy (cART) on health outcomes of HEU children (mitochondrial and metabolic toxicity, adverse pregnancy outcomes, neurodevelopment, growth, infectious morbidity, and mortality)...

P. vivax infection during pregnancy has been associated with poor outcomes such as anemia, low birth weight and congenital malaria, thus representing an important global health problem. However, no vaccine is currently available for its prevention. Vir genes were the first putative virulent factors associated with P. vivax infections, yet very few studies have examined their potential role as targets of immunity. We investigated the immunogenic properties of five VIR proteins and two long synthetic peptides containing conserved VIR sequences (PvLP1 and PvLP2) in the context of the PregVax cohort study including women from five malaria endemic countries: Brazil, Colombia, Guatemala, India and Papua New Guinea (PNG) at different timepoints during and after pregnancy...

Transcription factor EKLF (Erythroid Krüppel-Like Factor) belongs to the group of Krüppellike factors, which regulate proliferation, differentiation, development and apoptosis of mammalian cells. EKLF factor is present in erythroid cells, where it participates in regulation of hematopoiesis, expression of genes encoding transmembrane proteins (including blood group antigens), and heme biosynthesis enzymes. It is also a key factor in downregulation of γ-globins and activation of β-globin gene expression...

Although malaria is endemic in India, congenital malaria is not very common. Congenital malaria is a very rare condition in both endemic and nonendemic areas. We report a case of congenital malaria in a six-day-old neonate with fever and splenomegaly. The diagnosis was picked up accidentally on a peripheral smear examination. Congenital malaria should be kept as differential diagnosis of neonatal sepsis. Timely detection of this condition could lead to early diagnosis and treatment, thereby preventing neonatal mortality...

BACKGROUND: Congenital malaria, defined as the presence of asexual forms of malaria parasites in the peripheral blood during the first 7 days of life, remains a neglected area of research. Knowledge gaps exist about prevalence and management of malaria in this age group. The objective of this study was to evaluate the prevalence of congenital malaria and the validity of a rapid diagnostic test (RDT) for its diagnosis in rural Burundi. METHODS: A cross-sectional study was conducted in a meso-endemic malaria context in Burundi among 290 mothers, and their newborns (n = 303), who delivered at the maternity departments of Kirundo and Mukenke Hospitals during March and April 2014...

The majority of world's population-live in areas at risk of malaria transmission. Malaria is a serious Anopheles-borne disease that pauses symptoms like the flu, as a high fever, chills, and muscle pain also, anemia, bloody stools, coma, convulsion, fever, headache, jaundice, nausea, sweating and vomiting. Symptoms tend to come and go in cycles. Apart from Anopheles vector, malaria could be transmitted nosocomial, blood transfusion or needle-stick injury Some types of malaria may cause more serious damage problems to heart, lungs, kidneys, or brain...

BACKGROUND: The World Health Organization recommends intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP) in African regions with moderate to high malaria transmission. However, growing resistance to SP threatens the effectiveness of IPTp-SP, and alternative drugs are needed. This study tested the efficacy, tolerability, and safety of a fixed-dose combination azithromycin-chloroquine (AZCQ; 250 mg AZ/155 mg CQ base) for IPTp relative to IPTp-SP. METHODS AND FINDINGS: A randomized, Phase 3, open-label, multi-center study was conducted in sub-Saharan Africa (Benin, Kenya, Malawi, Tanzania, and Uganda) between October 2010 and November 2013...

PURPOSE OF REVIEW: Athough more than 90% of syphilis cases are diagnosed in developing countries, syphilis rates in industrialized countries have been increasing since the 1980s. Untreated syphilis in pregnancy is associated with high rates of adverse pregnancy outcomes, including fetal loss, premature birth, congenital syphilis, and neonatal death. We reviewed the recent literature on adverse pregnancy outcomes associated with untreated syphilis and the benefits of early and effective treatment...

Apicomplexan parasites cause diseases of medical and agricultural importance linked to dramatic changes they impart upon infected host cells. Following invasion, the malaria parasite Plasmodium falciparum renovates the host erythrocyte using mechanisms previously believed to be malaria-specific. This involves proteolytic cleavage of effectors in the endoplasmic reticulum that licences proteins for translocation into the host cell. Recently, it was demonstrated that the related parasite Toxoplasma gondii, responsible for disease in immunocompromised individuals and congenital birth defects, has an analogous pathway with some differences, including proteolytic processing in the Golgi...

PROBLEM/CONDITION: Malaria in humans is caused by intraerythrocytic protozoa of the genus Plasmodium. These parasites are transmitted by the bite of an infective female Anopheles mosquito. The majority of malaria infections in the United States occur among persons who have traveled to regions with ongoing malaria transmission. However, malaria is also occasionally acquired by persons who have not traveled out of the country through exposure to infected blood products, congenital transmission, laboratory exposure, or local mosquitoborne transmission...

BACKGROUND: Artemisinins, the most effective antimalarials available, are not recommended for falciparum malaria during the first trimester of pregnancy because of safety concerns. Therefore, quinine is used despite its poor effectiveness. Assessing artemisinin safety requires weighing the risks of malaria and its treatment. We aimed to assess the effect of first-trimester malaria and artemisinin treatment on miscarriage and major congenital malformations. METHODS: In this observational study, we assessed data from antenatal clinics on the Thai-Myanmar border between Jan 1, 1994, and Dec 31, 2013...

An estimated 2.6 million third trimester stillbirths occurred in 2015 (uncertainty range 2.4-3.0 million). The number of stillbirths has reduced more slowly than has maternal mortality or mortality in children younger than 5 years, which were explicitly targeted in the Millennium Development Goals. The Every Newborn Action Plan has the target of 12 or fewer stillbirths per 1000 births in every country by 2030. 94 mainly high-income countries and upper middle-income countries have already met this target, although with noticeable disparities...

The World Health Organization recommends artemisinin-based combination therapies (ACTs) for the treatment of uncomplicated falciparum malaria in the second and third trimesters of pregnancy. We conducted a meta-analysis to compare efficacy, safety and tolerability of ACTs versus quinine and other non-ACT antimalarials. The median PCR-adjusted failure rate by days 28 to 63 in the non-ACT group was 6 (range 0-37) per 100 women, lower in the ACT group overall (pooled risk ratio [PRR] random effects, 0.41; 95% confidence interval [CI], 0...

Neonates with congenital malaria may present with non-specific signs and symptoms which may be mistaken for neonatal sepsis and inborn error of metabolism resulting in delay of diagnosis.and significant mortality and morbidity. Here we present a unique case of 25 days old premature female baby who was diagnosed to have mixed malarial infection. Despite standard treatment the patient was not responding well and was also diagnosed to have congenital adrenal hyperplasia.

Congenital malaria is the presence of malarial parasites in the blood of newborns. The disease is acquired from mother either during pregnancy or perinatally at the time of birth. Congenital malaria in an endemic area can present without an obvious history of fever and parasitaemia in both mother and her infant. A case of Plasmodium vivax malaria in a 6-week infant is documented. Infant presented with pallor, jaundice and massive spleen. Laboratory tests revealed anaemia, thrombocytopenia and bilirubinemia...

Worldwide, 98% of stillbirths occur in low-income countries (LIC), where stillbirth rates are ten-fold higher than in high-income countries (HIC). Although most HIC stillbirths occur prenatally, in LIC most stillbirths occur at term and during labor/delivery. Conditions causing stillbirths include those of maternal origin (obstructed labor, trauma, antepartum hemorrhage, preeclampsia/eclampsia, infection, diabetes, other maternal diseases), and fetal origin (fetal growth restriction, fetal distress, cord prolapse, multiples, malpresentations, congenital anomalies)...
