PURPOSE: Cardiac implantable electronic devices (CIEDs) have traditionally been a contraindication for magnetic resonance imaging (MRI). Recent studies suggest that MRI can be conducted safely in select patients with pacemakers (PPMs) and implantable cardioverter defibrillators (ICDs). We sought to determine the safety of MRI in patients with CIEDs, using a protocol for patient selection and device programming. METHODS: This is a prospective, single-center study...

Preimplantation genetic diagnosis (PGD) has successfully assisted couples with genetic diseases to conceive healthy babies during the past decades. However, biopsy of the blastomere has potential lesion to the embryos which commonly results in abortion. Thus, a noninvasive PGD is needed. In the past, the presence of genetic materials in maternal plasma or serum has triggered a great innovation of noninvasive prenatal diagnosis. Nevertheless, it is not clear whether embryonic DNA is also present in embryonic culture medium...

Triploid plants are usually highly aborted owing to unbalanced meiotic chromosome segregation, but limited viable gametes can participate in the transition to different ploidy levels. In this study, numerous meiotic abnormalities were found with high frequency in an intersectional allotriploid poplar (Populus alba × P. berolinensis 'Yinzhong'), including univalents, precocious chromosome migration, lagging chromosomes, chromosome bridges, micronuclei, and precocious cytokinesis, indicating high genetic imbalance in this allotriploid...

Cambodia's current abortion rate and ratio could be among the highest in Southeast Asia. In 1997, the Cambodian parliament passed the first law regulating abortions. This law was adopted to contribute to reduce the high maternal mortality ratio, as a significant number of maternal deaths were believed to be related to complications of unsafe abortion. A decade later, the Ministry of Health had not yet established medical protocols for safe abortion access and women often continued to induce their own terminations or seek unsafe services...

The Epstein-Barr virus (EBV) is a gamma-herpesvirus associated with several malignancies. It establishes a latent infection in B lymphocytes and is occasionally reactivated to enter the lytic cycle. Here we examined the role of the EBV gene BRRF1, which is expressed in the lytic state. We first confirmed, using a DNA polymerase inhibitor, that the BRRF1 gene is expressed with early kinetics. A BRRF1-deficient recombinant virus was constructed using a bacterial artificial chromosome system. No obvious differences were observed between the wild-type, BRRF1-deficient mutant and the revertant virus in HEK293 cells in terms of viral lytic protein expression, viral DNA synthesis, progeny production, pre-latent abortive lytic gene expression and transformation of primary B cells...

OBJECTIVES: Differentiation of an eccentric intrauterine pregnancy (IUP) from an interstitial ectopic pregnancy (EP) is challenging. No sign for differentiation is reported. The purpose of this study was to determine whether the presence of surrounding endometrium (SE) can distinguish eccentric IUP from interstitial EP. METHODS: This study was approved by the institutional ethics board; consent acquisition was waived. Cases were identified using ultrasound (US) reports that included the words "interstitial," "cornual," and "angular...

Twenty years after the introduction of alcohol septal ablation (ASA) for the treatment of obstructive hypertrophic cardiomyopathy, the arrhythmogenicity of the ablation scar appears to be overemphasized. When systematically reviewing all studies comparing ASA with myectomy with long-term follow-up, (aborted) sudden cardiac death and mortality rates were found to be similarly low. The focus should instead shift toward lowering the rate of reinterventions and pacemaker implantations following ASA because, in this area, ASA still seems inferior to myectomy...

BACKGROUND: Long QT syndrome (LQTS) is a potentially lethal cardiac channelopathy with a 1% to 5% annual risk of LQTS-triggered syncope, aborted cardiac arrest, or sudden cardiac death. OBJECTIVES: This study sought to evaluate LQTS outcomes from a single center in the contemporary era. METHODS: The authors conducted a retrospective study comprising the 606 patients with LQTS (LQT1 in 47%, LQT2 in 34%, and LQT3 in 9%) who were evaluated in Mayo Clinic's Genetic Heart Rhythm Clinic from January 1999 to December 2015...

As long-term survival is high for children and young adults diagnosed with leukemia and lymphoma, delineating maternal, fetal and offspring health risks is important to their family planning. This systematic review examined data comparing these health risks between leukemia and lymphoma survivors and women without a history of cancer. Following a search of Embase, PubMed, CINAHL, Cochrane, and Web of Science, 142 articles were screened and 18 were included in this review. No higher risks of spontaneous abortion, maternal diabetes and anemia, stillbirth, birth defects, or childhood cancer in offspring were observed in survivors compared to controls...

The Zika virus epidemic rapidly spread across Brazil and Latin America, gaining international attention because of the causal relationship between Zika and birth defects. The high number of cases in Brazil has been attributed to a failure of the state to contain the epidemic and protect the affected people, especially women. Therefore, the public health crisis created by Zika exposed a stark conflict between Brazil's constitutional right to health and the long-standing violation of reproductive rights in the country...

Consumption of ponderosa pine needles, as well as needles and bark from a number of other trees, can cause abortions in cattle. The abortifacient compounds in these trees are labdane resin acids, including isocupressic acid and agathic acid. Previous research has demonstrated that cattle conditioned to pine needles metabolize the labdane resin acids more quickly than naïve cattle. The results from that study indicated that changes had occurred in the rumen of conditioned cattle. Therefore, in this study, the changes that occurred in the rumen bacterial microflora of cattle during exposure to ponderosa pine needles were evaluated...

Toxoplasma gondii is considered as one of the most successful intracellular pathogens, because it can reproduce in varied nutritional milieus, encountered in diverse host-cell types of essentially any warm-blooded organism. Our earlier work has demonstrated that the acute (tachyzoite) stage of T. gondii depends on cooperativity of glucose and glutamine catabolism to meet biosynthetic demands. Either of these two nutrients can sustain the parasite survival; however, what determines the metabolic plasticity has not been resolved yet...

AIM: To explore attitudes to safe-induced abortion among pregnant women in Iran. BACKGROUND: In Islamic teachings abortion is generally forbidden. However in specific circumstances abortion may be permitted and currently, in Iran, the law allows termination of pregnancy only if three specialist physicians confirm that the pregnancy outcome may be harmful for the mother during pregnancy or after birth. DESIGN: Pilot, descriptive survey. METHODS: A 15-item structured questionnaire focusing on attitudes to safe-induced abortion was developed and pilot tested...

Questions concerning the beginning of human life have pervaded society since antiquity. In the post-modern world, scientific and technological advances have fueled discussions on the issue, such that debates previously concentrated on abortion now also focus on biotechnological interventions. The article addresses the latter, reflecting on the extent to which human dignity can be considered a (hermeneutic) reference in establishing ethical and legal parameters for biotechnological advances in the definition of the beginning of human life...

GOALS: To examine the impact of maternal hepatitis B virus infection on pregnancy outcomes. BACKGROUND: Studies regarding hepatitis B virus infection and pregnancy outcomes are limited with inconsistent results, and none of them have evaluated the effect of maternal viral load in pregnancy on pregnancy outcomes. STUDY: A hospital-based case-control study was conducted. In total, 1728 hepatitis B surface antigen (HBsAg)-positive women who delivered consecutively at Wuhan Women and Children Medical and Healthcare Center, Wuhan, China, from June 2008 to May 2015, were compared with 1497 HBsAg-negative women giving birth in the same hospital during the same period who were randomly identified and selected from the computerized medical record database in parallel...

We present a series of four pregnant women with Rocky Mountain spotted fever (RMSF) that occurred in Sonora, Mexico, during 2015-2016. Confirmatory diagnoses were made by polymerase chain reaction or serological reactivity to antigens of Rickettsia rickettsii by using an indirect immunofluorescence antibody assay. Each patient presented with fever and petechial rash and was treated successfully with doxycycline. Each of the women and one full-term infant delivered at 36 weeks gestation survived the infection...

The degree of fetal growth restriction has been unclear in equine reproduction. In this study, 2,195 fetuses from 2,137 abortions during 11 seasons were examined to determine the causes of abortion, and fetal size dimensions (crown rump length and body weight) were measured. In total, 900 cases (42.1%) of abortion were identified as caused by viral infection (215, 10.1%), bacterial infection (156, 7.3%), fungal infection (25, 1.2%), circulation failure (406, 19.0%), multiple causes (66, 3.1%), deformity (13, 0...
