Researchers have observed in some studies that brain tumor patients (or their mothers) have generally consumed more cured foods (also known as Curing) than control groups. Recently, Drs. Lee, Wrensch and others found that adults with glioma were more likely to consume diets high in cured foods and low in vitamin C-rich fruits and vegetables, and to consume diets high in nitrites and low in vitamin C. The effect was more pronounced in men than women. However, the pattern of increased risk with increased consumption of cured foods, and decreased risk with greater consumption of fruits, vegetables, and antioxidant vitamins is compatible with other cancer studies that show increased consumption of vegetables and possibly of fruits is associated with decreased cancer risk. Radiation
A link between gliomas and electromagnetic radiation from cell phones has not been conclusively proven. It was considered possible, though several large studies have found no conclusive evidence, as summarized by the NIHs National Cancer Institute review of the topic and its numerous citations, and the FCC. However, further research is still being pursued to obtain more robust evidence and verify that there is no relationship (the NIHs National Institute of Environmental Health Sciences most recent press release discussed an ongoing study showing mildly positive results, although it appears there may have been issues with the control group dying prematurely). Infection with cytomegalovirus
Some studies have reported that glioblastomas are infected with cytomegalovirus, with suggestions that this may speed the development of tumors.
Prolonged labor is the inability of a woman to proceed with childbirth upon going into labor. Prolonged labor typically lasts over 20 hours for first time mothers, and over 14 hours for women that have already had children. Failure to progress can take place during two different phases; the latent phase and active phase of labor. The latent phase of labor can be emotionally tiring and cause fatigue, but it typically does not result in further problems. The active phase of labor, on the other hand, if prolonged, can result in long term complications.It is important that the vital signs of the woman and fetus are being monitored so preventive measures can be taken if prolonged labor begins. Women experiencing prolonged labor should be under supervision of a surgically equipped doctor. Prolonged labor is determined based on the information that is being collected regarding the strength and time between contractions. Medical teams track this data using intrauterine pressure catheter placement (IUPC) and continuous electronic fetal monitoring (EFM). IUPC is a straw that is inserted into the womb with a monitor that reads when contractions are coming and how strong they are. EFMs are used to track the fetal heart rate. If either devices indicate that vital signs are off and prolonged labor is beginning, it is important that the medical team begin discussing treatment and alternative options for delivery. Prolonged labor can result from a variety of different issues, such as fetal malpresentation, issues with uterine contractions, cervical dystocia  or stenosis, and cephalopelvic disproportion.
