Ground penetrating radar used to detect drowning victims under ice.

Unlabelled: Every year, people drown after falling through ice on rivers and lakes. In some cases, the body of the victim floats up to the underside of the ice, making detection and recovery difficult using traditional search methods with divers. A robust and contact-less sensing system is required to locate drowning victims that does not put rescue teams at risk of falling through the ice themselves.

Generation of Prior Information in a Dual-Mode Microwave-Ultrasound Breast Imaging System.

A new breast imaging system capable of obtaining ultrasound and microwave scattered-field measurements with minimal or no movement of the breast between measurements has recently been reported. In this work, we describe the methodology that has been developed to generate prior information about the internal structures of the breast based on ultrasound data measured with the dual-mode system. This prior information, estimating both the geometry and complex-valued permittivity of tissues within the breast, is incorporated into the microwave inversion algorithm as a means of enhancing image quality.

Novel Stopping Criteria for Optimization-Based Microwave Breast Imaging Algorithms.

A discontinuous Galerkin formulation of the Contrast Source Inversion algorithm (DGM-CSI) for microwave breast imaging employing a frequency-cycling reconstruction technique has been modified here to include a set of automated stopping criteria that determine a suitable time to shift imaging frequencies and to globally terminate the reconstruction. Recent studies have explored the use of tissue-dependent geometrical mapping of the well-reconstructed real part to its imaginary part as initial guesses during consecutive frequency hops. This practice was shown to improve resulting 2D images of the dielectric properties of synthetic breast models, but a fixed number of iterations was used to halt DGM-CSI inversions arbitrarily.

Intranasal Sufentanil Versus Intravenous Morphine for Acute Pain in the Emergency Department: A Randomized Pilot Trial.

Background: Patients in the United States frequently seek medical attention in the emergency department (ED) to address their pain. The intranasal (i.n.

Exome-Wide Rare Variant Analyses in Sudden Infant Death Syndrome.

Objective: To determine whether a monogenic basis explains sudden infant death syndrome (SIDS) using an exome-wide focus.

Study Design: A cohort of 427 unrelated cases of SIDS (257 male; average age = 2.7 ± 1.

Noncardiac genetic predisposition in sudden infant death syndrome.

Purpose: Sudden infant death syndrome (SIDS) is the commonest cause of sudden death of an infant; however, the genetic basis remains poorly understood. We aimed to identify noncardiac genes underpinning SIDS and determine their prevalence compared with ethnically matched controls.

Methods: Using exome sequencing we assessed the yield of ultrarare nonsynonymous variants (minor allele frequency [MAF] ≤0.

Dysfunction of NaV1.4, a skeletal muscle voltage-gated sodium channel, in sudden infant death syndrome: a case-control study.

Background: Sudden infant death syndrome (SIDS) is the leading cause of post-neonatal infant death in high-income countries. Central respiratory system dysfunction seems to contribute to these deaths. Excitation that drives contraction of skeletal respiratory muscles is controlled by the sodium channel NaV1.

Cardiac Genetic Predisposition in Sudden Infant Death Syndrome.

Background: Sudden infant death syndrome (SIDS) is a leading cause of postneonatal mortality. Genetic heart diseases (GHDs) underlie some cases of SIDS.

Objectives: This study aimed to determine the spectrum and prevalence of GHD-associated mutations as a potential monogenic basis for SIDS.

Organ weights and ratios for postmortem identification of fetal growth restriction: utility and confounding factors.

Objectives: The postmortem fetal brain:liver weight ratio is commonly used as a marker of nutrition for diagnosis of fetal growth restriction (FGR). However, there are limited data regarding the effects of intrauterine retention, fetal maceration and postmortem interval on organ weights and their ratios at autopsy. Our aims were to examine the relationships between gestational-age-adjusted and sex-adjusted fetal organ weights at autopsy, cause of intrauterine death and effects of intrauterine retention, and to determine whether the brain:liver weight ratio is a reliable marker of FGR in intrauterine death.

Stillbirth and intrauterine fetal death: contemporary demographic features of >1000 cases from an urban population.

Objectives: Of 780 000 births annually in the UK, around 3300 are stillborn, a rate of approximately 4 per 1000 births. Traditional epidemiological associations are based on historic data. The aim of this study was to document contemporary demographic findings in a large series of > 1000 deaths in utero in London and compare these with national datasets.

Stillbirth and intrauterine fetal death: role of routine histopathological placental findings to determine cause of death.

Objectives: Placental abnormalities are a common cause of death in stillbirth, ranking second only to unexplained deaths, though there is wide variation in the proportion attributed to placental disease. In clinical practice, interpretation of the significance of placental findings is difficult, since many placental features in stillbirths overlap with those in live births. Our aim was to examine objectively classified placental findings from a series of > 1000 autopsies following intrauterine death in order to evaluate the role of placental histological examination in determining the cause of death.

Quantifying the impact of dissimilar HPV vaccination uptake among Manitoban school girls by ethnicity using a transmission dynamic model.

Background: Gardasil, a human papillomavirus (HPV) vaccine, began among grade 6 girls in Manitoba, Canada in 2008. In Manitoba, there is evidence that First Nations, Métis, and Inuit women (FNMI) have higher HPV prevalence, lower invasive cervical cancer (ICC) screening, and higher ICC incidence than all other Manitoban (AOM) women. We developed a mathematical model to assess the plausible impact of unequal vaccination coverage among school girls on future cervical cancer incidence.

Post tsunami psychological impact among survivors in Aceh and West Sumatra, Indonesia.

Objective: In 2004, the province of Aceh, Indonesia was rocked by tsunami and in September 2009, West Sumatra, Indonesia was hit by an earthquake. The aim of this study was to determine the long-term psychological impact on the residents inhabiting these regions and to identify factors associated with it.

Methods: A cross-sectional study was conducted among the residents.

Expression of the RNA-binding protein RBM3 is associated with a favourable prognosis and cisplatin sensitivity in epithelial ovarian cancer.

Background: We recently demonstrated that increased expression of the RNA-binding protein RBM3 is associated with a favourable prognosis in breast cancer. The aim of this study was to examine the prognostic value of RBM3 mRNA and protein expression in epithelial ovarian cancer (EOC) and the cisplatin response upon RBM3 depletion in a cisplatin-sensitive ovarian cancer cell line.

Methods: RBM3 mRNA expression was analysed in tumors from a cohort of 267 EOC cases (Cohort I) and RBM3 protein expression was analysed using immunohistochemistry (IHC) in an independent cohort of 154 prospectively collected EOC cases (Cohort II).

Cognitive modifiability of children with developmental disabilities: a multicentre study using Feuerstein's Instrumental Enrichment--Basic program.

The study aimed at exploring the effectiveness of cognitive intervention with the new "Instrumental Enrichment Basic" program (IE-basic), based on Feuerstein's theory of structural cognitive modifiability that contends that a child's cognitive functioning can be significantly modified through mediated learning intervention. The IE-basic progam is aimed at enhancing domain-general cognitive functioning in a number of areas (systematic perception, self-regulation abilities, conceptual vocabulary, planning, decoding emotions and social relations) as well as transferring learnt principles to daily life domains. Participants were children with DCD, CP, intellectual impairment of genetic origin, autistic spectrum disorder, ADHD or other learning disorders, with a mental age of 5-7 years, from Canada, Chile, Belgium, Italy and Israel.

Embolism of brain tissue in intrapartum and early neonatal deaths: report of 9 cases.

We report the clinical features and pathological findings in 9 cases of intrapartum and early neonatal death associated with embolism of brain tissue to the pulmonary and systemic circulation following difficult delivery. All except 1 of the cases in this series were born at, or near to, term, were vertex presentations, and were normally grown. All followed instrumental delivery and in 5, at least one mode of assisted delivery had failed.

Congenital vascular malformations: a series of five prenatally diagnosed cases.

In the literature there are single case reports of mediastinal/chest and limb combined vascular malformations (previously labeled "hemangiolymphangiomas"). A variable outcome in such prenatally diagnosed cases is reported. Presented here is the only series of patients reported with these macrocystic, predominantly lymphatic malformations.

Interferon-alpha induces sensitization of cells to inhibition of protein synthesis by tumour necrosis factor-related apoptosis-inducing ligand.

Tumour cells are often sensitized by interferons to the effects of tumour necrosis factor-alpha-related apoptosis-inducing ligand (TRAIL). We have demonstrated previously that TRAIL has an inhibitory effect on protein synthesis [Jeffrey IW, Bushell M, Tilleray VJ, Morley S & Clemens MJ (2002) Cancer Res62, 2272-2280] and we have therefore examined the consequences of prior interferon-alpha treatment for the sensitivity of translation to inhibition by TRAIL. Interferon treatment alone has only a minor effect on protein synthesis but it sensitizes both MCF-7 cells and HeLa cells to the downregulation of translation by TRAIL.

Oral clindamycin and histologic chorioamnionitis in women with abnormal vaginal flora.

Objective: Oral clindamycin reduced late miscarriage and preterm birth in asymptomatic women with bacterial vaginosis or intermediate flora. We investigated whether clindamycin reduced the incidence of histologic chorioamnionitis as a mechanism for these beneficial effects.

Methods: This was a subanalysis of 126 participants from a larger randomized controlled trial.
