Cancer
3,619 female participants of the Childhood Cancer Survivor Study and 2,081 of their female siblings were asked to complete a questionnaire. Overall, women who were 5-year survivors of childhood cancer were as likely as their siblings to report a pregnancy. However, those who had received radiation doses ≥22 Gy to treat hypothalamic or pituitary cancer had a decreased chance of pregnancy compared with the cancer survivors who had not received radiation therapy.
Metabolism
Phosphate incorporation during glycogen synthesis and Lafora disease Tagliabracci, V. S. et al. Cell Metab. 13, 274–282 (2011)
Glycogen synthase can incorporate β-phosphate from its substrate (UDP-glucose) at a rate of one per 10,000 glucose molecules, which could be a catalytic error. Lafora disease, a fatal progressive myoclonus epilepsy, is caused by hyperphosphorylation of glycogen; therefore, removal of phosphate by laforin could be a repair or damage control mechanism.
Cardiovascular endocrinology
Relationship between neck circumference and cardiometabolic parameters in HIV-infected and non-HIV-infected adults Fitch, K. V. et al. Diabetes Care 34, 1026–1031 (2011)
In an analysis of 174 men and women with HIV and 154 without the infection, a large neck circumference was associated with reduced levels of HDL cholesterol and poor glucose homeostasis in both groups of patients. In those without HIV, neck circumference was also predictive of increased carotid intima–media thickness.
Obesity
The expression levels of microRNAs (miRNAs) in the omentum, subcutaneous fat and blood of 50 obese and nonobese patients were compared. Expression of miR-17-5p and miR-132 in the omentum fat of obese patients were different to the expression in nonobese patients. In those with obesity, the expression profiles in omental fat and blood correlated with BMI, fasting blood glucose and HbA1c; therefore, miRNAs could be used as biomarkers for the metabolic syndrome.
