What Do You Do For Breast Milk Jaundice?
Discussion
Almost all infants in the first few days of life have some elevation of their bilirubin because of the various physiologic changes they undergo in the transition to extra-uterine life. This is a common problem managed by many different inpatient and outpatient healthcare providers. This hyperbilirubinemia is usually unconjugated and resolves in the first 1-2 weeks of life. However, when it does not resolve, health care providers have 3 general paths to follow when considering a cause: inadequate breast milk intake, an underlying organic cause or breast milk jaundice.
Inadequate breastfeeding is not uncommon and...

Targeting tumor phenotypic plasticity and metabolic remodeling in adaptive cross-drug tolerance
Metastable phenotypic state transitions in cancer cells can lead to the development of transient adaptive resistance or tolerance to chemotherapy. Here, we report that the acquisition of a phenotype marked by increased abundance of CD44 (CD44Hi) by breast cancer cells as a tolerance response to routinely used cytotoxic drugs, such as taxanes, activated a metabolic switch that conferred tolerance against unrelated standard-of-care chemotherapeutic agents, such as anthracyclines. We characterized the sequence of molecular events that connected the induced CD44Hi phenotype to increased activity of both the glycolytic and oxid...

Relationship of glucose-6-phosphate dehydrogenase deficiency and neonatal sepsis: a single-center investigation on the major cause of neonatal morbidity and mortality
This study was designed to investigate the relationship between G6PD deficiency and neonatal sepsis, since it is a major cause of neonatal morbidity and mortality. Our study showed higher incidence of G6PD deficiency in neonates who had been admitted due to sepsis. We suggest quantitative G6PD-level assessment instead of the routine qualitative methods in prevalent G6PD deficiency. It is also recommended that neonates with G6PD deficiency be under close supervision during the first month of life, especially those with other risks of neonatal sepsis, such as prematurity or low birth weight.

Safety of vitamin C in sepsis: a neglected topic.
Although vitamin C is essentially a nontoxic vitamin; however, it is important to be aware regarding the safety of high doses before the wide clinical use. Minor side effects of vitamin C have been reported, many being reported in earlier studies. High doses of vitamin C (up to 1.5 g/kg three times a week as intravenously) were safe in cancer patients with normal renal function and perfect glucose-6-phosphate dehydrogenase activity. As the dose and duration of administration of vitamin C in sepsis are lower and shorter than those used in cancer patients, it seems that it is relatively safe for this population. In ...

Cochrane seeks Clinical Research Associate - Liverpool, UK
Liverpool school of Tropical Medicine ' s Centre for Evidence Synthesis in Global Health has led developments in systematic reviews in tropical medicine and international health. In the 1990s, staff contributed to setting up Cochrane, and established theCochrane Infectious Diseases Group (CIDG). This is now recognised as one of Cochrane ' s premier groups, with over 150 Cochrane reviews and 600 authors, and is well-linked with the World Health Organization.We are looking to expand the centre. As part of this, we are recruiting staff for the "Research, Evidence and Development Initiative " (READ-It) programme that is just...

Mitochondrial redox sensing by the kinase ATM maintains cellular antioxidant capacity
Mitochondria are integral to cellular energy metabolism and ATP production and are involved in regulating many cellular processes. Mitochondria produce reactive oxygen species (ROS), which not only can damage cellular components but also participate in signal transduction. The kinase ATM, which is mutated in the neurodegenerative, autosomal recessive disease ataxia-telangiectasia (A-T), is a key player in the nuclear DNA damage response. However, ATM also performs a redox-sensing function mediated through formation of ROS-dependent disulfide-linked dimers. We found that mitochondria-derived hydrogen peroxide promoted ATM d...

23andMe is back: FDA allows marketing of genetic health risk tests
[Image courtesy of 23andMe]FDA this month allowed genetic testing company 23andMe to market genetic health risk tests for 10 diseases and conditions including Parkinson’s disease and late-onset Alzheimer’s disease.
The de novo premarket review authorization, announced April 6, also included celiac disease, which results in the inability to digest gluten; alpha-1 antitrypsin deficiency, which raises the risk of lung and liver disease; early-onset primary dystonia, a movement disorder; factor XI deficiency, a blood clotting disorder; Gaucher disease type 1, a disorder involving organs and tissue; glucose-6-phosphate deh...

Red blood cell traits associated with malaria risk in children
Certain red blood cell traits in children can increase or decrease their risk for malaria, researchers say. Researchers also found that a genetic condition known as homozygous X-linked G6PD deficiency correlated with a reduced risk of malaria in girls only. Meanwhile, HbC-trait, in which the body makes an abnormal hemoglobin called hemoglobin C, appeared to increase malaria risk in children. Scientists hope this study will lead to further research into the molecular mechanisms of the malaria-protective effects of red blood cell variants. (Source: ScienceDaily Headlines)

What Medicines Should Be Avoided with G6PD Deficiency?
Discussion
Glucose 6-phosphate dehydrogenase deficiency (G6PD) is an X-linked disease that has multiple mutations. Each mutation causes a different amount of the enzyme to be produced within cells and therefore not all mutations will produce disease. Glucose 6-phosphate dehydrogenase is an enzyme that is critical to the metabolism of all aerobic cells as it catalyzes the rate-limiting step of the pentose phosphate pathway reducing NADP to NADPH. NADPH is important for nucleic acid replication and therefore cell division. G6PD is the only source of NADPH within the cell, so deficiency makes red blood cells susceptible to he...
