BACKGROUND: Leukaemia remains the most common type of paediatric cancer and its aetiology remains unknown, but considered to be multifactorial. It is suggested that the initiation in utero by relevant exposures and/or inherited genetic variants and, other promotional postnatal exposures are probably required to develop leukaemia. This study aimed to map the incidence and analyse possible clusters in the geographical distribution of childhood acute leukaemia during the critical periods and to evaluate the factors that may be involved in the aetiology by conducting community and individual risk assessments...

INTRODUCTION: To ascertain whether combined ultrasound assessment of fetal head circumference (HC) and maternal subpubic angle (SPA) prior to the onset of labour may predict the likelihood of an unplanned operative delivery (UOD) in nulliparous women at term. MATERIAL AND METHODS: Prospective cohort study of singleton pregnancies in cephalic presentation. Pregnancies experiencing UOD secondary to fetal distress were excluded. HC was assessed transabdominally while SPA values were obtained from a reconstructed coronal plane on three-dimensional(3D) ultrasound performed trans-labially at 36-38 weeks of gestation...

Autism spectrum disorder is a complex trait with a high degree of heritability as well as documented susceptibility from environmental factors. In this study the contributions of copy number variation, exposure to air pollutants, and the interaction between the two on autism risk, were evaluated in the population-based case-control Childhood Autism Risks from Genetics and Environment (CHARGE) Study. For the current investigation, we included only those CHARGE children (a) who met criteria for autism or typical development and (b) for whom our team had conducted both genetic evaluation of copy number burden and determination of environmental air pollution exposures based on mapping addresses from the pregnancy and early childhood...

BACKGROUND: Use of narcotic or "recreational" drugs has been associated with adverse pregnancy outcomes such as preterm delivery. However, the associations might be confounded by other factors related to high-risk behaviours. This is the first study to investigate the association between traditional opium use during pregnancy and risk of preterm delivery. METHOD AND FINDINGS: We performed a population-based cohort study in the rural areas of the Golestan province, Iran between 2008 and 2010...

In this study, we examine the phenomenology of maternal identity development among U.S. women hospitalized with medically high risk pregnancies (MHRP). We conducted 16 in-depth interviews with women and find that they drew on culturally normative notions of maternal nurture, worry, and sacrifice to construct maternal identity in the context of MHRP. Based on our findings, we suggest that MHRP shapes women's sense of a unique connection to and distinctive cognitive representations of their fetus that are facilitated by the use of technology...

INTRODUCTION: A cesarean section is the most frequently performed surgery in modern obstetrics. In case of an incorrect wound healing process there is a risk of a persistent uterine wall defect. Nowadays, due to the high frequency of cesarean sections, obstetricians have to deal with the threat of uterine rupture due to pathological wound healing. It has been proven that isthmocele can cause abnormal uterine bleeding (AUB), pelvic pain (PP), and secondary infertility (SI), and can be a place of improper pregnancy placement...

BACKGROUND: Gestational diabetes mellitus (GDM) is one of the common complications that occur during pregnancy. Early intervention is essential to prevent the development of the disease in the non-pregnant state but also helpful in preventing the occurrence of GDM. The aim of the study was to assess the effect of aerobic exercises on insulin sensitivity and fasting plasma glucose level in pregnant women with risk for gestational diabetes mellitus. MATERIALS AND METHODS: Forty multigravidae women between 20-24 weeks of gestation with risk for GDM were randomly selected (age range was 25-35 years), body mass index ranged from 30-35 kg/m(2)...

Anemia and micronutrient (MN) deficiencies in pregnant women are associated with adverse pregnancy outcomes. In Niger, 58.6% of pregnant women are anemic; however, MN statuses are unknown. The study objectives were to estimate the prevalence of MN deficiencies among pregnant women in Zinder, Niger and explore associated risk factors. Pregnant women living in randomly selected rural villages (n = 88) were included. Capillary and venous blood samples (n = 770) were analyzed for hemoglobin (Hb) and plasma ferritin, soluble transferrin receptor (sTfR), zinc (pZn), retinol binding protein (RBP), folate and vitamin B12...

STUDY QUESTION: Is pregnancy outcome in triplet pregnancies improved with embryo reduction (ER) to twins compared to expectant management? SUMMARY ANSWER: In trichorionic triplet pregnancies, ER to twins reduces the risk of preterm birth (<34 weeks) without significantly increasing the risk of miscarriage (<24 weeks), whereas in dichorionic triplet pregnancies, the results are inconclusive. WHAT IS KNOWN ALREADY: Triplet pregnancies are associated with a high risk of miscarriage and preterm birth...

Attention-deficit/hyperactivity disorder (ADHD) has an uncertain etiology, with potential contributions from different risk factors such as prenatal environmental exposure to organochlorines and metals, social risk factors, and genetics. The degree to which geographic variability in ADHD is independent of, or explained by, risk factors may provide etiological insight. We investigated determinants of geographic variation in ADHD-related behaviors among children living near the polychlorinated biphenyl-contaminated New Bedford Harbor (NBH) Superfund site in Massachusetts...

We use a data-driven global stochastic epidemic model to analyze the spread of the Zika virus (ZIKV) in the Americas. The model has high spatial and temporal resolution and integrates real-world demographic, human mobility, socioeconomic, temperature, and vector density data. We estimate that the first introduction of ZIKV to Brazil likely occurred between August 2013 and April 2014 (90% credible interval). We provide simulated epidemic profiles of incident ZIKV infections for several countries in the Americas through February 2017...

This study aims to investigate the fetal outcomes and associated factors of adverse pregnancy outcomes (APOs) in pregnant women with systemic lupus erythematosus (SLE). Clinical data from 251 SLE patients with 263 pregnancies from 2001 to 2015 were analyzed retrospectively. APOs occurred in 70.0% of pregnancies, in which pregnancy loss occurred in 28.5%; preterm delivery occurred in 21.3%; intrauterine growth retardation occurred in 12.2%; and fetal distress occurred in 8.0%. Over time, the rate of APOs decreased from 82...

PROBLEM: Herpes simplex virus 1 (HSV-1) commonly causes orolabial infection, but can also infect the genital mucosa. In contrast, HSV-2 is usually genital. Genital herpes can transmit the virus vertically to the fetus during pregnancy. We sought to estimate the prevalence of HSV-1/2 on the maternal and fetal sides of the placenta. METHOD OF STUDY: Placental tissues were collected from pregnant women seen at the Rio Grande University Hospital. HSV-1 and HSV-2 were detected by nested PCR...

As Japan has achieved one of the lowest perinatal mortality rates (PMR), our study aims to estimate trends in and risk factors for perinatal mortality among singleton births in Japan. We used Japanese vital registration data to assess trends in and risk factors for perinatal outcomes between 1979 and 2010. Birth and death registration data were merged. An autoregressive integrated moving average model was fitted separately by sex to the PMR and the proportion of stillbirths. A multilevel Poisson regression model was used to estimate risk factors for perinatal mortality...

REVIEW
Lorenzo Rossi, Olivia Pagani
In the last few years, new adjuvant endocrine treatment options have become available in young women with early breast cancer, such as the addition of ovarian function suppression to tamoxifen or aromatase inhibitors. Treatment duration has been also adapted in the latest guidelines based on the individual risk of recurrence. The oncologist is therefore challenged to precisely assess the risk of recurrence according to currently available predictive and prognostic factors in order to offer the most appropriate therapeutic option to the individual patient, considering also potential side effects, quality of life, pregnancy planning and patients' preferences...

BACKGROUND: Obesity prevalence is increasing in Australia, particularly in non-metropolitan areas. The effect of obesity on acute surgical outcomes is not known. We aimed to record waist circumference (WC) (surrogate for obesity) amongst acute surgical unit (ASU) patients in a New South Wales regional hospital, and compare outcome measures (length of stay (LOS), unplanned return to theatre, readmission rates, intensive care unit (ICU) admission and mortality). METHODS: Retrospective cohort study of 4 months of consecutive ASU admissions, excluding age <16, pregnancy, out-of-area transfer and incomplete data...
