PURPOSE: Hypertension in pregnancy has been associated with decreased future risk of breast cancer in many but not all studies. In the Marin Women's Study, pregnancy-induced hypertension was shown to interact with the T allele of a functional IGF1R gene variant, rs2016347, to result in lower breast density, as well as decreased breast cancer risk. Our objective was to explore these findings in a larger sample of women from the California Teachers Study (CTS). METHODS: The CTS cohort consists of over 130,000 female educators...

Duchenne muscular dystrophy (DMD) is a rare, fatal X-linked disorder characterized by the lack of dystrophin, a key sarcolemma muscle protein. Cardiac failure is a significant cause of death in DMD subjects. The purpose of our research was to identify potential cardiac serum biomarkers associated with DMD cardiomyopathy. This is an observational, case-controlled study using subjects from the CINRG DMD natural history study with cardiomyopathy (ejection fraction (EF) <55%; shortening fraction (SF) <28%), subjects without cardiomyopathy (EF ≥ 55%; SF ≥ 28%) compared to normal healthy volunteer subjects...

The island rule describes a graded trend in insular populations of vertebrates from gigantism in small species to dwarfism in large species. The dwarfing of large mammals on islands has been observed both in the present fauna and in the fossil record. Elephants, hippopotami, deer, and other species became dwarfed on islands scattered all over the world, from the Mediterranean Sea to Indonesia, from the Eastern to Western Pacific Ocean, from the Caribbean to Canary Islands. The most rapid and well documented cases of island dwarfing known thus far took place over thousands of years...

The dwindling wildlife species of our planet have become a cause célèbre for conservation groups, governments, and concerned citizens throughout the world. The application of powerful new genetic technologies to surviving populations of threatened mammals has revolutionized our ability to recognize hidden perils that afflict them. We have learned new lessons of survival, adaptation, and evolution from viewing the natural history of genomes in hundreds of detailed studies. A single case history of one species, the African cheetah, Acinonyx jubatus, is here reviewed to reveal a long-term story of conservation challenges and action informed by genetic discoveries and insights...

In cognitive radio communication, spectrum sensing plays a vital role in sensing the existence of the primary user (PU). The sensing performance is badly affected by fading and shadowing in case of single secondary user(SU). To overcome this issue, cooperative spectrum sensing (CSS) is proposed. Although the reliability of the system is improved with cooperation but existence of malicious user (MU) in the CSS deteriorates the performance. In this work, we consider the Kullback-Leibler (KL) divergence method for minimizing spectrum sensing data falsification (SSDF) attack...

Lynch syndrome (LS) is a hereditary cancer syndrome caused by a germline mutation in a DNA mismatch repair gene, usually MLH1, MSH2, MSH6, or PMS2. The most common cancers associated with LS are colorectal adenocarcinoma and endometrial carcinoma. Identification of women with LS-associated endometrial cancer is important, as these women and their affected siblings and children are at-risk of developing these same cancers. Germline testing of all endometrial cancer patients is not cost effective, and screening using young age of cancer diagnosis and/or presence of family history of syndrome-associated is underutilized and ineffective...

Gastrointestinal stromal tumor (GIST), the most common mesenchymal neoplasm of the gastrointestinal tract, exhibits diverse histologic and clinical manifestations. With its putative origin in the gastrointestinal pacemaker cell of Cajal, GIST can arise in association with any portion of the tubular gastrointestinal tract. Morphologically, GISTs are classified as spindled or epithelioid, though each of these subtypes encompasses a broad spectrum of microscopic appearances, many of which mimic other histologic entities...

Fecal contamination of drinking water is associated with large hepatitis E virus (HEV) outbreaks of genotypes 1 and 2 in endemic areas. Sporadic transmission of HEV genotypes 3 and 4 in high-income countries has been associated with exposure to blood and animal contact. The objective of the study was to identify the risk factors for hepatitis E and the genotype(s) causing sporadic hepatitis E in Dhaka, Bangladesh. We selected, from a diagnostic center in Dhaka between November 2008 and November 2009, cases presenting with jaundice and anti-HEV IgM antibodies and age-matched controls were defined as those with no history of jaundice and normal blood test results...

The number of new syphilis cases in Brazil has risen alarmingly in recent years. However, there is limited data regarding syphilis prevalence in the Brazilian prison population. To facilitate the development of effective interventions, a cross-sectional study was undertaken to determine the prevalence of Treponema pallidum infection, active syphilis, and associated risk factors among Brazilian prisoners. We administered a questionnaire to a population-based sample of prisoners from 12 prisons in Central-West Brazil and collected sera for syphilis testing, from January to December 2013...

Purpose In the United States, 3.8 million women have a history of breast (BC) or ovarian cancer (OC). Up to 15% of cases are attributable to heritable mutations, which, if identified, provide critical knowledge for treatment and preventive care. It is unknown how many patients who are at high risk for these mutations have not been tested and how rates vary by risk criteria. Methods We used pooled cross-sectional data from three Cancer Control Modules (2005, 2010, 2015) of the National Health Interview Survey, a national in-person household interview survey...

Major obstetric hemorrhage is the leading cause of maternal morbidity and mortality. In rare cases, life-threatening hemorrhage in pregnant women may result from abnormal adherence of placenta. Three grades of abnormal placental attachment are defined according to the depth of invasion: placenta accreta, placenta increta, and placenta percreta. An important risk factor for placenta abnormal adherence of placenta is placenta previa in the presence of a uterine scar. The increased prevalence of cesarean section, uterine surgery, and increasing parturient age and parity have led to an increased incidence of abnormal placentation, from one in 2,500 a quarter century ago, to one in 533 deliveries currently...

Occurrence of pregnancy after in vitro fertilization depends of two components: functional adequacy of the embryo at the blastocyst stage and receptivity of endometrium, which, according to modern perception, are determinate in achieving optimal conditions of implantation. From the pregnancy occurrence point of view, as well as in regard to its further development , implantation is the most crucial phase of IVF/ICSI and ET. As the same time, this phase is also the most vulnerable. Multiple researches have proven the role of mother thrombophilia for genesis of gestation complications and early embryo losses, but in relation to this problem i the context of IVF there is still a lot to be detailed...

We describe a case of a 13-year-old male patient of Coats' disease who developed sympathetic ophthalmia (SO) following contact diode laser cyclophotocoagulation. There was no history of invasive surgery or any perforating injuries preceding cyclodestructive therapy. The eye had neovascular glaucoma secondary to Coats' disease, which was treated once with contact cyclophotocoagulation. Subsequently, the intraocular pressure slowly decreased, and the eye became phthisical. Intraocular inflammation developed in the fellow eye and SO was suspected, which was confirmed by characteristic findings seen on fluorescein angiography...
