BACKGROUND: Women play important roles in translating health knowledge, particularly around pregnancy and birth, in Indigenous societies. We investigated elder Indigenous women's perceptions around optimal perinatal health. METHODS: Using a methodological framework that integrated a constructivist grounded-theory approach with an Indigenous epistemology, we conducted and analyzed in-depth interviews and focus groups with women from the Six Nations community in southern Ontario who self-identified as grandmothers...

Myofibroma is a rare, benign myofibroblastic tumor that commonly presents at birth or in early infancy, usually as a painless, slow-growing, solitary, nodular mass. We present a case of a 40-year-old woman with a painful, solitary, myofibroma on the right elbow. The unique features of this case include age and gender of the patient, site, pain on presentation, tumor morphology, and putative intravascular nature of the tumor.

Edward Korzus
Rubinstein-Taybi syndrome (RSTS) is a rare genetic disorder in humans characterized by growth and psychomotor delay, abnormal gross anatomy, and mild to severe mental retardation (Rubinstein and Taybi, Am J Dis Child 105:588-608, 1963, Hennekam et al., Am J Med Genet Suppl 6:56-64, 1990). RSTS is caused by de novo mutations in epigenetics-associated genes, including the cAMP response element-binding protein (CREBBP), the gene-encoding protein referred to as CBP, and the EP300 gene, which encodes the p300 protein, a CBP homologue...

BACKGROUND: A male fetus is suggested to be more susceptible to in utero and birth complications. This may be due in part to altered morphology or function of the XY placenta. We hypothesised that sexual dimorphism begins at the blastocyst stage with sex differences in the progenitor trophectoderm (TE) and its derived trophoblast lineages, as these cells populate the majority of cell types within the placenta. We investigated sex-specific differences in cell allocation in the pre-implantation embryo and further characterised growth and gene expression of the placental compartments from the early stages of the definitive placenta through to late gestation...

BACKGROUND: Arsenic in drinking water has been associated with adverse reproductive outcomes in areas with high levels of naturally occurring arsenic. Less is known about the reproductive effects of arsenic at lower levels. OBJECTIVES: This research examined the association between low-level arsenic in drinking water and small for gestational age (SGA), term low birth weight (term LBW), very low birth weight (VLBW), preterm birth (PTB), and very preterm birth (VPTB) in the state of Ohio...

BACKGROUND: Despite recommendations that women give birth with a skilled birth attendant (SBA), 70% of births in Guatemala occur outside health facilities with informally trained traditional birth attendants (TBAs). To increase SBA in rural, indigenous communities, a professional midwifery school accredited by the government is scheduled to open in 2017. Drawing from Filby's model on barriers to the successful integration of professional midwifery into health systems, this paper aims to identify threats - and facilitators-toward professional midwifery's re-introduction in Guatemala...

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...

Ureaplasma spp. are associated with preterm birth. In recent times, it has become apparent that U. parvum, but not U. urealyticum, is of most relevance. We recently demonstrated this in Australian pregnant women and using high-resolution melt (HRM) PCR, further showed that U. parvum genotype SV6 was of particular significance. However, our assay was unable to identify multiple genotypes in the same sample, required a separate species-level qPCR for low titre samples and was not ideal for diagnostic laboratories due to the nature of HRM PCR result interpretation...

INTRODUCTION: Spinal cord injury (SCI) has increased over the years, and so has the survival. Women with SCI remain fertile and have equal chance of pregnancy. CASE PRESENTATION: We described a case of a 29-year-old lady with traumatic spinal cord injury (SCI) resultant with paraplegia in 2008, who conceived naturally 2 years after the injury. She only had her antenatal check-up at a low-risk antenatal center throughout her pregnancy and was not referred to specialized obstetric care...

BACKGROUND: The developmentally important DLK1-DIO3 imprinted domain on human chromosome 14 is regulated by two differentially methylated regions(DMRs), the IG-DMR and the MEG3 DMR. OBJECTIVES: The aim was to determine the natural variation in DNA methylation at these DMRs in human placentas, and to determine its link to gene expression levels at the domain. Second, to explore whether the domain's methylation and gene expression correlate with pre- and early-postnatal growth of the conceptus...

Polycystic ovary syndrome (PCOS) is a complex endocrinopathy that is characterized by anovulation, hyperandrogenism and polycystic ovary. However, there is a lack of effective treatment for PCOS at present because the pathologic cause of PCOS has not been elucidated. Although it has been known that brown adipose tissue transplantation ameliorates PCOS by activating endogenous BAT, BAT transplantation is not applicable in clinic. Therefore, BAT activation with natural compound could be an effective treatment strategy for PCOS patients...

AbstractMalaria incidence is highly heterogeneous even in areas of high transmission, although no conclusive evidence exists that innate or naturally acquired resistance can prevent infection over an extended period of time. This longitudinal study examined immunoparasitological evidence for a malaria-resistant phenotype in which children do not develop malaria despite an extended period of exposure to parasites. Within a birth cohort followed from 2002 to 2006 in Muheza, Tanzania, an area of intense transmission, children (N = 687) provided blood smears biweekly during infancy and monthly thereafter...

Cancer is a genetic disorder, meaning that a plethora of different mutations, whether somatic or germ line, underlie the etiology of the 'Emperor of Maladies'. Point mutations, chromosomal rearrangements and copy number changes, whether they have occurred spontaneously in predisposed individuals or have been induced by intrinsic or extrinsic (environmental) mutagens, lead to the activation of oncogenes and inactivation of tumor suppressor genes, thereby promoting malignancy. This scenario has now been recognized and experimentally confirmed in a wide range of different contexts...

PURPOSE OF REVIEW: Arsenic, a known carcinogen and developmental toxicant, is a major threat to global health. While the contribution of arsenic exposure to chronic diseases and adverse pregnancy and birth outcomes is recognized, its ability to impair critical functions of humoral and cell-mediated immunity-including the specific mechanisms in humans-is not well understood. Arsenic has been shown to increase risk of infectious diseases that have significant health implications during pregnancy and early life...

STUDY QUESTION: What is the cost-effectiveness of lifestyle intervention preceding infertility treatment in obese infertile women? SUMMARY ANSWER: Lifestyle intervention preceding infertility treatment as compared to prompt infertility treatment in obese infertile women is not a cost-effective strategy in terms of healthy live birth rate within 24 months after randomization, but is more likely to be cost-effective using a longer follow-up period and live birth rate as endpoint...

OBJECTIVES: HIV-exposed uninfected (HEU) infants have higher rates of severe and fatal infections compared with HIV-unexposed (HUU) infants, likely due to immune perturbations. We hypothesized that alterations in natural killer (NK) cell activity might occur in HEU infants and predispose them to severe infections. DESIGN: Case-control study using cryopreserved peripheral blood mononuclear cells (PBMCs) at birth and 6 months from HEU infants enrolled from 2002 to 2009 and HUU infants enrolled from 2011 to 2013...
