The potential of residual clinical Group B Streptococcus swabs for assessing the vaginorectal microbiome in late pregnancy.

The maternal pregnancy microbiome (including genitourinary and gut) has been linked to important pregnancy/birth and later childhood health outcomes. However, such sampling as part of large population cohort studies is logistically and financially challenging. Many countries routinely collect vaginal or vaginal-rectal swabs in late pregnancy for Group B Streptococcus (GBS) screening, but their utility for population-based research is still unclear.

The Lawlessness of Loss: Poetry and Autoethnographic Writing as Therapy in Grief and Loss.

This study seeks to locate and evaluate 'poetry therapy' as a form of therapeutic method for use by practitioners of humanistic psychotherapy especially when used in responding to the traumas associated with grief and loss. Following an initial survey of the literature, the study will explore some examples of the use of poetry therapy for grief, with an especial qualitative focus upon the insights to be gained from first-hand autoethnographic accounts. The study undertakes a literature review which also includes some consideration of peer-reviewed autoethnographic explorations authored by theorists and practitioners of psychotherapy in order to identify what additional insights, if any, may be gained from accessing these personal accounts of process.

Childhood cancer survival in the highly vulnerable population of South Texas: A cohort study.

This study examines childhood cancer survival rates and prognostic factors related to survival in the majority Hispanic population of South Texas. The population-based cohort study used Texas Cancer Registry data (1995-2017) to examine survival and prognostic factors. Cox proportional hazard models and Kaplan-Meier survival curves were used for survival analyses.

Breastfeeding practices and associations with pregnancy, maternal and infant characteristics in Australia: a cross-sectional study.

Background: Exclusive breastfeeding to six months of age is a major global public health priority. Several characteristics are known to be associated with early cessation of breastfeeding, however, limited evidence exists regarding whether women's reported reasons for cessation are associated with maternal, pregnancy and infant characteristics. The aims of this study were to: i) describe women's reported intention to breastfeed and their subsequent breastfeeding practices; ii) describe women's reported reasons for breastfeeding cessation prior to the infant being five months of age; and iii) examine associations between these factors and maternal, pregnancy and infant characteristics.

The risks of birth defects and childhood cancer with conception by assisted reproductive technology.

Study Question: Is there an association between fertility status, method of conception and the risks of birth defects and childhood cancer?

Summary Answer: The risk of childhood cancer had two independent components: (i) method of conception and (ii) presence, type and number of birth defects.

What Is Known Already: The rarity of the co-occurrence of birth defects, cancer and ART makes studying their association challenging. Prior studies have indicated that infertility and ART are associated with an increased risk of birth defects or cancer but have been limited by small sample size and inadequate statistical power, failure to adjust for or include plurality, differences in definitions and/or methods of ascertainment, lack of information on ART treatment parameters or study periods spanning decades resulting in a substantial historical bias as ART techniques have improved.

Assessment of Birth Defects and Cancer Risk in Children Conceived via In Vitro Fertilization in the US.

Importance: Children with birth defects have a greater risk of developing cancer, but this association has not yet been evaluated in children conceived with in vitro fertilization (IVF).

Objective: To assess whether the association between birth defects and cancer is greater in children conceived via IVF compared with children conceived naturally.

Design, Setting, And Participants: This cohort study of live births, birth defects, and cancer from Massachusetts, New York, North Carolina, and Texas included 1 000 639 children born to fertile women and 52 776 children conceived via IVF (using autologous oocytes and fresh embryos) during 2004-2016 in Massachusetts and North Carolina, 2004-2015 in New York, and 2004-2013 in Texas.

Immunoglobulin G from single plasma donor in immune globulin intravenous causes false positive pyrogen test.

A sudden, unprecedented failure of USP rabbit pyrogen tests for multiple 10% IGIV-C lots prompted a thorough investigation of the root cause for this phenomenon. All microbe-related testing, including Limulus amebocyte lysate test for endotoxin, proved negative, and no deficiencies were discovered in manufacturing. Plasma pool composition analysis revealed that a single plasma donor ("Donor X″) was common to all pyrogenic IGIV-C lots and that as little as one unit of "Donor X″ plasma (in a pool of ∼4500 units) was sufficient to cause IGIV-C lot failure in the USP rabbit pyrogen test.

Association of In Vitro Fertilization With Childhood Cancer in the United States.

Importance: In vitro fertilization (IVF) is associated with birth defects and imprinting disorders. Because these conditions are associated with an increased risk of childhood cancer, many of which originate in utero, descriptions of cancers among children conceived via IVF are imperative.

Objective: To compare the incidence of childhood cancers among children conceived in vitro with those conceived naturally.

Zonation of Ca transport and enzyme activity in the caeca of rainbow trout - a simple structure with complex functions.

Trout caeca are vermiform structures projecting from the anterior intestine of the gastrointestinal tract. Despite their simple gross morphology, these appendages are physically distinct along the anterior-posterior axis, and ultrastructural evidence suggests zonation of function within the structures. Individual caeca from three sections (anterior, middle and posterior) were removed from the intestine of freshwater rainbow trout and investigated for ion transport and enzyme activity.

Behavioral and Neurochemical Phenotyping of Mice Incapable of Homer1a Induction.

Immediate early and constitutively expressed products of the gene regulate the functional assembly of post-synaptic density proteins at glutamatergic synapses to influence excitatory neurotransmission and synaptic plasticity. Earlier studies of gene knock-out (KO) mice indicated active, but distinct, roles for IEG and constitutively expressed gene products in regulating cognitive, emotional, motivational and sensorimotor processing, as well as behavioral and neurochemical sensitivity to cocaine. More recent characterization of transgenic mice engineered to prevent generation of the IEG form (a.

The RUDY study: using digital technologies to enable a research partnership.

Patients have extensive experience of their disease that can enhance the design and execution of research leading to significant innovations and efficiencies in the research process. The research community on the whole have been slow to adopt practices that enable patients to become active partners in research. Digital technologies are providing the means to do this more easily and so are increasingly being used to interact with patients and involve them in the design and execution of research.

Truncated Latrunculins as Actin Inhibitors Targeting Plasmodium falciparum Motility and Host Cell Invasion.

Polymerization of the cytosolic protein actin is critical to cell movement and host cell invasion by the malaria parasite, Plasmodium falciparum. Any disruption to actin polymerization dynamics will render the parasite incapable of invading a host cell and thereby unable to cause infection. Here, we explore the potential of using truncated latrunculins as potential chemotherapeutics for the treatment of malaria.

CYP3A5 Mediates Effects of Cocaine on Human Neocorticogenesis: Studies using an In Vitro 3D Self-Organized hPSC Model with a Single Cortex-Like Unit.

Because of unavoidable confounding variables in the direct study of human subjects, it has been difficult to unravel the effects of prenatal cocaine exposure on the human fetal brain, as well as the cellular and biochemical mechanisms involved. Here, we propose a novel approach using a human pluripotent stem cell (hPSC)-based 3D neocortical organoid model. This model retains essential features of human neocortical development by encompassing a single self-organized neocortical structure, without including an animal-derived gelatinous matrix.

Applicability of the Calgary-Cambridge Guide to Dog and Cat Owners for Teaching Veterinary Clinical Communications.

Effective communication in health care benefits patients. Medical and veterinary schools not only have a responsibility to teach communication skills, the American Veterinary Medical Association (AVMA) Council on Education (COE) requires that communication be taught in all accredited colleges of veterinary medicine. However, the best strategy for designing a communications curriculum is unclear.

Embryo banking among women diagnosed with cancer: a pilot population-based study in New York, Texas, and Illinois.

Purpose: The purpose of the present study is to estimate the proportion of women with cancer who return to use the embryos that they have banked and to compare this proportion to that of women without cancer who bank embryos.

Methods: This is a cohort study of three groups of women from New York, Texas, and Illinois who used embryo banking in their first assisted reproductive technology (ART) treatment cycle: two groups with cancer (222 women without an infertility diagnosis and 48 women with an infertility diagnosis) and a control group without cancer (68 women with the infertility diagnosis of male factor only). Women were included only if their first ART cycle reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) occurred between 2004 and 2009.

Assisted reproductive technology use and outcomes among women with a history of cancer.

Study Question: How do the assisted reproductive technology (ART) outcomes of women presenting for ART after cancer diagnosis compare to women without cancer?

Summary Answer: The likelihood of a live birth after ART among women with prior cancer using autologous oocytes is reduced and varies by cancer diagnosis but is similar to women without cancer when donor oocytes are used.

What Is Known Already: Premenopausal patients faced with a cancer diagnosis frequently present for fertility preservation.

Study Design, Size, Duration: Population-based cohort study of women treated with ART in NY, TX and IL, USA.

Two Essential Light Chains Regulate the MyoA Lever Arm To Promote Toxoplasma Gliding Motility.

Unlabelled: Key to the virulence of apicomplexan parasites is their ability to move through tissue and to invade and egress from host cells. Apicomplexan motility requires the activity of the glideosome, a multicomponent molecular motor composed of a type XIV myosin, MyoA. Here we identify a novel glideosome component, essential light chain 2 (ELC2), and functionally characterize the two essential light chains (ELC1 and ELC2) of MyoA in Toxoplasma.

Cancer in women after assisted reproductive technology.

Objective: To evaluate the risk of cancer after assisted reproductive technology (ART) therapy.

Design: Longitudinal cohort study.

Setting: Not applicable.

Functional consequences of 17q21.31/WNT3-WNT9B amplification in hPSCs with respect to neural differentiation.

Human pluripotent stem cell (hPSC) lines exhibit repeated patterns of genetic variation, which can alter in vitro properties as well as suitability for clinical use. We examined associations between copy-number variations (CNVs) on chromosome 17 and hPSC mesodiencephalic dopaminergic (mDA) differentiation. Among 24 hPSC lines, two karyotypically normal lines, BG03 and CT3, and BG01V2, with trisomy 17, exhibited amplification of the WNT3/WNT9B region and rapid mDA differentiation.

All-cancers mortality rates approaching diseases of the heart mortality rates as leading cause of death in Texas.

Objectives: Diseases of the heart and malignant neoplasms (all-cancers) are the leading causes of death in the United States. The gap between the two has been closing in recent years. To assess the gap status in Texas and to establish a baseline to support evaluation efforts for the Cancer Prevention Research Institute of Texas, mortality data from 2006 to 2009 were analyzed.

Silica desiccant packets for storage and transport of Streptococcus pneumoniae and other clinically relevant species.

Bacterial isolates are often transported between laboratories for research and diagnostic purposes. Silica desiccant packets (SDPs), which are inexpensive and do not require freezing, were evaluated for storage and recovery of bacterial isolates. Conditions such as inoculum size, swab type and temperature of storage were investigated using ten Streptococcus pneumoniae isolates.

Muddy water? Variation in reporting receipt of breast cancer radiation therapy by population-based tumor registries.

Purpose: To evaluate, in the setting of breast cancer, the accuracy of registry radiation therapy (RT) coding compared with the gold standard of Medicare claims.

Methods And Materials: Using Surveillance, Epidemiology, and End Results (SEER)-Medicare data, we identified 73,077 patients aged ≥66 years diagnosed with breast cancer in the period 2001-2007. Underascertainment (1 - sensitivity), sensitivity, specificity, κ, and χ(2) were calculated for RT receipt determined by registry data versus claims.

Disparities in the treatment and outcomes of lung cancer among HIV-infected individuals.

Objectives: HIV-infected people have elevated risk for lung cancer and higher mortality following cancer diagnosis than HIV-uninfected individuals. It is unclear whether HIV-infected individuals with lung cancer receive similar cancer treatment as HIV-uninfected individuals.

Design/methods: We studied adults more than 18 years of age with lung cancer reported to the Texas Cancer Registry (N = 156 930) from 1995 to 2009.
