Thyroid carcinoma is the first cancer found in general population and the second diagnosed during pregnancy following the breast one. Diagnostic and therapeutic approaches to thyroid malignancy in pregnant women pose several and serious issues to the physicians. Even if there is no consensus about the surgical treatment of thyroid carcinomas during pregnancy, a large number of women undergo surgery over the world. The best surgical and anesthesiological treatment should be chosen after reaching a consensus between surgeons, anesthesiologists, obstetrics, and the patients...

OBJECTIVE: The factors angiopoeitin-2 (Ang-2), endoglin (Eng), and placental growth factor (PlGF) have been implicated in the pathophysiology of preeclampsia (PE). This study assessed their serum levels in HIV-negative and HIV-positive pregnant normotensive and pre-eclamptic women. METHODS: Participants were recruited at the antenatal clinic, serum samples were evaluated using the Bioplex Human Cancer Biomarker (panel 2). RESULTS: Ang-2 and Eng levels were higher, whilst PlGF levels were lower in the PE compared with the normotensive group...

Biological responses to carcinogens from environmental exposure during adulthood are modulated over years or decades. Conversely, during transplacental exposure, the effects on the human foetus change within weeks, intertwining with developmental mechanisms: even short periods of transplacental exposure may be imprinted in the organism for a lifetime. The pathways leading to childhood and juvenile cancers, such as leukaemias, neuroblastoma/brain tumours, hepatoblastoma, and Willm's tumor involve prenatally-induced genomic, epigenomic and/or non-genomic effects caused by xenobiotics...

Metformin is everywhere. Originally introduced in clinical practice as an anti-diabetic agent, its role as a therapeutic agent is expanding to include treatment of pre-diabetes, gestational diabetes, polycystic ovarian disease, and more recently, experimental studies, as well as observations in randomized clinical trials, suggest that metformin could have a place in the treatment or prevention of preeclampsia. This article provides a brief overview of the history of metformin in the treatment of diabetes, reviews the results of meta-analyses of metformin in gestational diabetes, and the treatment of obese non-diabetic pregnant women to prevent macrosomia...

Imaging during pregnancy has increased in frequency. Radiation protection is extremely important although tissue reactions of the conceptus, requiring a threshold dose of around 100mGy, are unlikely in the diagnostic use of X-rays and stochastic effects of cancerogenesis have a rather low risk (around 10(-4)/mGy for childhood cancer due to in utero exposure). This article will review the risk depending on dose and phase of pregnancy and the exposure by frequent examinations; it will then concentrate on the duties of an imaging department: screening for pregnancy, examination justification, planning and optimization, patient information, counseling, involving the patient in the decisions, and managing the situation of pregnant staff members...

Folate deficiency has been linked to a wide range of disorders, including cancer, neural tube defects, and fetal growth restriction. Folate regulates cellular function mediated by its involvement in the synthesis of nucleotides, which are needed for DNA synthesis, and its function as a methyl donor, which is critical for DNA methylation. Here we review current data showing that folate sensing by mechanistic target of rapamycin (mTOR) constitutes a novel and distinct pathway by which folate modulates cell functions such as nutrient transport, protein synthesis, and mitochondrial respiration...

Differentiated thyroid cancer (DTC) is markedly more common in women than men, the highest female-to-male ratio being recorded during the reproductive period. This evidence has led to the suggestion that female hormonal and reproductive factors may account for the observed DTC gender disparity. This review focuses on current evidence on the risk of DTC in conjunction with major female reproductive factors, including the impact of pregnancy on DTC occurrence and progression/recurrence. Overall, studies exploring the link between the risk of DTC and menstrual and menopausal factors, oral contraceptives and/or hormone replacement therapy, showed these associations, if any, to be generally weak...

Epigenetic changes such as DNA methylation may be a molecular mechanism through which environmental exposures affect health. Phthalates are known endocrine disruptors with ubiquitous exposures in the general population including pregnant women, and they have been linked with a number of adverse health outcomes. We examined the association between in utero phthalate exposure and altered patterns of cord blood DNA methylation in 336 Mexican-American newborns. Concentrations of 11 phthalate metabolites were analyzed in maternal urine samples collected at 13 and 26 weeks gestation as a measure of fetal exposure...

Colorectal cancer is a rare occurrence during pregnancy and can present with symptoms that are common during pregnancy such as constipation.This can make the diagnosis of colorectal cancer during pregnancy difficult. Management of colorectal cancer during pregnancy is similar to the treatment of non-pregnant patients, but with fetal safety in mind. This case report describes a 33-year-old female gravida two para one (G2P1) at 29 weeks gestation who presented with a complete bowel obstruction. Colonoscopy, magnetic resonance imaging (MRI) and later resection showed an obstructing malignancy which was then resected through an exploratory laparotomy with left hemicolectomy...

It is well known that ketamine abuse can induce liver damage in adult addicts, but the effects of ketamine abuse in pregnant mothers on their offspring have received less attention. In this study, we investigated the effects of 5-day ketamine injections (30 mg/kg) to pregnant Institute for Cancer Research (ICR) mice during early gestation or mid-gestation on the aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activities of the mothers and the offspring. We also looked into whether administering ketamine treatment to the mothers had any effects on the extent of fibrosis, cell proliferation and cell death in the livers of the newborns...

OBJECTIVES: One of every four pregnant women in Chile is obese. Gestational obesity is associated with maternal metabolic complications in pregnancy (e.g., gestational diabetes, preeclampsia), but to our knowledge, there is little evidence on relationships with future metabolic risk. The aim of this study was to evaluate the association between prepregnancy obesity (prepregnancy body mass index ≥30 kg/m(2)) or excessive gestational weight gain (GWG; according to the 2009 recommendations from the Institute of Medicine), and maternal metabolic complications 10 y postpartum in premenopausal Chilean women...

REVIEW
Paolo Zanotti-Fregonara, Elif Hindie
The number of nuclear medicine examinations performed worldwide has been steadily increasing over the last few years. By consequence, an ever increasing number of pregnant women are likely to be exposed to radioisotopes. The range of doses encountered in nuclear medicine practice is well below the threshold for deterministic effects, such as embryonic death, birth defects or mental retardation. According to the linear no-threshold hypothesis, however, stochastic effects (e.g. an increased risk of cancer) remain possible even at this dose range...
