Benefits of fetal echocardiographic surveillance in pregnancies at risk of congenital heart block: single‐center study of 212 anti‐Ro52‐positive pregnancies

Assuming that autoimmune congenital heart block (CHB) is a progressive disease amenable to therapeutic modulation, we introduced a surveillance program for at‐risk pregnancies with the dual aim of investigating if fetal atrioventricular block (AVB) could be detected and treated before becoming complete and irreversible, and to establish the incidence of AVB I, II and III in a large prospective cohort.
Unveiling an ‘invisible population’: health, substance use, sexual behavior, culture, and discrimination among urban American Indian/Alaska Native adolescents in California

ABSTRACT Objectives: There are limited public health data on urban American Indian/Alaska Native (AI/AN) populations, particularly adolescents. The current study attempted to address gaps by providing descriptive information on experiences of urban AI/AN adolescents across northern, central, and southern California. Design: We describe demographics and several behavioral health and cultural domains, including: alcohol and other drug (AOD) use, risky sexual behavior, mental and physical health, discrimination experiences, involvement in traditional practices, and cultural pride and belonging. We recruited 185 urban AI/AN adolescents across northern, central, and southern California from 2014 to 2017 who completed a baseline survey as part of a randomized controlled intervention trial. Results: Average age was 15.6 years; 51% female; 59% of adolescents that indicated AI/AN descent also endorsed another race or ethnicity. Rates of AOD use in this urban AI/AN sample were similar to rates for Monitoring the Future. About one-third of adolescents reported ever having sexual intercourse, with 15% reporting using alcohol or drugs before sex. Most reported good mental and physical health. Most urban AI/AN adolescents participated in traditional practices, such as attending Pow Wows and learning their tribal history. Adolescents also reported discrimination experiences, including being a victim of racial slurs and discrimination by law enforcement. Conclusions: This study describes a select sample of California urban AI/AN adolescents across several behavioral health and cultural domains. Although these adolescents reported numerous discrimination experiences and other stressors, findings suggest that this sample of urban AI/AN teens may be particularly resilient with regard to behavioral health.
Resveratrol supplementation during in vitro maturation improves embryo development of prepubertal goat oocytes selected by brilliant cresyl blue staining

This study aimed to investigate the effect of resveratrol supplementation in maturation medium on the developmental ability and bioenergetic\oxidative status of prepubertal goat oocytes selected by brilliant cresyl blue (BCB). Oocytes collected from slaughterhouse-derived ovaries were selected by 13 µM BCB staining and classified as grown BCB+ and growing BCB- oocytes. All oocytes were matured in vitro in our conventional maturation medium and supplemented with 1 µM (BCB+R and BCB-R) and without (Control groups: BCB+C and BCB-C) resveratrol. After 24 h, IVM-oocytes were fertilized with fresh semen and presumptive zygotes were in vitro cultured for 8 days. Oocytes were assessed for blastocyst development and quality, mitochondrial activity and distribution, and levels of GSH, ROS, and ATP. BCB+R (28.3%) oocytes matured with resveratrol presented significantly higher blastocyst development than BCB+C (13.0%) and BCB- groups (BCB-R: 8.3% and BCB-C: 4.7%). Resveratrol improved blastocyst development of BCB-R oocytes at the same rate as BCB+C oocytes. No differences were observed in blastocyst quality among groups. GSH levels were significantly higher in resveratrol groups (BCB+R: 36554.6; BCB-R: 34946.7 pixels/oocyte) than in control groups (BCB+C: 27624.0; BCB-C: 27655.4 pixels/oocyte). No differences were found in mitochondrial activity, ROS level, and ATP content among the groups. Resveratrol-treated oocytes had a higher proportion of clustered active mitochondria in both BCB groups (BCB+R: 73.07%; BCB-R: 79.16%) than control groups (BCB+C: 19.35%; BCB-C: 40%). In conclusion, resveratrol increased blastocyst production from oocytes of prepubertal goats, particularly in better quality oocytes (BCB+).
Lateral Transport of Organic and Inorganic Solutes

Organic (e.g., sugars and amino acids) and inorganic (e.g., K+, Na+, PO42−, and SO42−) solutes are transported long-distance throughout plants. Lateral movement of these compounds between the xylem and the phloem, and vice versa, has also been reported in several plant species since the 1930s, and is believed to be important in the overall resource allocation. Studies of Arabidopsis thaliana have provided us with a better knowledge of the anatomical framework in which the lateral transport takes place, and have highlighted the role of specialized vascular and perivascular cells as an interface for solute exchanges. Important breakthroughs have also been made, mainly in Arabidopsis, in identifying some of the proteins involved in the cell-to-cell translocation of solutes, most notably a range of plasma membrane transporters that act in different cell types. Finally, in the future, state-of-art imaging techniques should help to better characterize the lateral transport of these compounds on a cellular level. This review brings the lateral transport of sugars and inorganic solutes back into focus and highlights its importance in terms of our overall understanding of plant resource allocation.
Phosphodiesterase type 5 inhibitor attenuates chronic ischemia‐induced prostatic hyperplasia in a rat model

Many elderly men suffer from benign prostatic hyperplasia (BPH). Recently, chronic ischemia in the prostate has been suggested to be related to BPH. Thus, the impact of chronic ischemia on the development of prostatic hyperplasia and the efficacy of phosphodiesterase type 5 (PDE5) inhibitor for hyperplasia were evaluated in a rat model with chronic ischemia induced by local atherosclerosis.
Inhibition of chemotherapy resistant breast cancer stem cells by a ROR1 specific antibody

Significance We report that breast cancer cells surviving treatment with paclitaxel express relatively high levels of ROR1, which can induce activation of stem-cell signaling pathways in response to Wnt5a. A humanized anti-ROR1 drug, cirmtuzumab, can inhibit ROR1-dependent activation of such signaling and impair the capacity of post-treatment breast cancer cells to metastasize or reengraft immune-deficient mice. Breast cancers enduring treatment with chemotherapy may be enriched for cancer stem cells or tumor-initiating cells, which have an enhanced capacity for self-renewal, tumor initiation, and/or metastasis. Breast cancer cells that express the type I tyrosine kinaselike orphan receptor ROR1 also may have such features. Here we find that the expression of ROR1 increased in breast cancer cells following treatment with chemotherapy, which also enhanced expression of genes induced by the activation of Rho-GTPases, Hippo-YAP/TAZ, or B lymphoma Mo-MLV insertion region 1 homolog (BMI1). Expression of ROR1 also enhanced the capacity of breast cancer cells to invade Matrigel, form spheroids, engraft in Rag2−/−γc−/− mice, or survive treatment with paclitaxel. Treatment of mice bearing breast cancer patient-derived xenografts (PDXs) with the humanized anti-ROR1 monoclonal antibody cirmtuzumab repressed expression of genes associated with breast cancer stemness, reduced activation of Rho-GTPases, Hippo-YAP/TAZ, or BMI1, and impaired the capacity of breast cancer PDXs to metastasize or reengraft Rag2−/−γc−/− mice. Finally, treatment of PDX-bearing mice with cirmtuzumab and paclitaxel was more effective than treatment with either alone in eradicating breast cancer PDXs. These results indicate that targeting ROR1 may improve the response to chemotherapy of patients with breast cancer.
A Brief History of Sequence Logos

The seeds of the origin of sequence logos were planted in early 1980s when researchers, equipped with large amounts of DNA and RNA sequence data, started to develop keen interest in understanding how base (A, C, G and T/U) composition at different positions of these aligned sequences, together with the compositional patterns at neighboring positions, contribute to structural and functional properties. For example, a protein or a macromolecule tends to bind at a site in the DNA that has a characteristic pattern. Initial attempts to determine this pattern focused on building a consensus sequence from many aligned sequences-however, this approach was criticized for its lack of predictive power [1,2]. In 1986, Schneider et al. [3] proposed measures to estimate the amount of information at each site of the sequence. An obvious next step was to visualize succinctly, this flow of information along the sequence and the proportional contribution of the different bases to the information content at each position. This resulted in the origin of sequence logo plots in 1990 in a seminal work by Schneider & Stephens [4].
The prognostic potential of long noncoding RNA HOTAIR expression in human digestive system carcinomas: A meta‐analysis

Homeobox transcript antisense intergenic RNA (HOTAIR), one of the well‐known long noncoding RNAs (lncRNAs), plays an important role in initiation and development of various tumors. Elevated level of HOTAIR is associated with metastatic behavior of primary tumor and poor outcome in several cancers. Therefore, we conducted a meta‐analysis to clearly measure the prognostic impact of HOTAIR in patients with digestive system carcinomas. Fourteen studies including 2,666 patients with five different type of digestive system cancers were selected to be entered in meta‐analysis. Finding demonstrated that HOTAIR overexpression could predict unfavorable outcome in digestive system carcinomas (hazard ratio [HR] = 2.4, 95% confidence interval [CI]: 2.0–2.9; p < 0.001; fixed‐effect model). In stratified analysis, increased level of HOTAIR predicted poor overall survival in gastric cancer (HR = 2.1, 95% CI: 1.6–2.9; p < 0.001), colorectal cancer (HR = 4.1, 95% CI: 1.6–10.2; p = 0.002), esophageal squamous cell carcinoma (HR = 2.3, 95% CI: 1.7–3.0; p < 0.001), and hepatocellular carcinoma (HR = 3.4, 95% CI: 1.9–6.1; p < 0.001). Our meta‐analysis results clearly support the prognostic value of HOTAIR to predict unfavorable prognostic outcomes in diverse digestive system carcinomas.
Health-care use and information needs of children with neonatal brachial plexus palsy: A cross-sectional survey among 465 Dutch patients

To investigate health-care use (HCU) and information needs of children aged 0–18 years with neonatal brachial plexus palsy (NBPP), a cross-sectional study was performed. Patients and/or parents seen in our NBPP clinic were invited to complete a survey comprising questions on HCU due to NBPP and current information needs. Outcomes were described for three age-groups (0–1/2–9/10–18 years), based on follow-up status (early/late/no-discharge). Four hundred sixty-five parents/patients participated (59 in the 0–1, 226 in the 2–9, and 180 in the 10–18-year group). Two hundred ninety-three patients had C5–C6 lesions, 193 were discharged from follow-up, 83 of whom categorized as ‘early discharged’ (<1 year of age). Over the past year, 198 patients had contact with the expert team (49 in the 0–1, 81 in the 2–9, and 68 in the 10–18-year group) and 288 with at least one other health-care professional (53 in the 0–1, 133 in the 2–9, and 102 in the 10–18-year group). Of the 83 patients discharged early, 34 reported health-care use. Two hundred twenty-eight participants reported current information needs of whom 23 were discharged early. HCU and information needs of Dutch children with NBPP remains considerable even in children who were discharged. Stricter follow-up and information provision for these patients is needed.
Tissue-mimicking materials for breast phantoms up to 50 GHz

Millimeter (mm)-wave imaging has been recently proposed as a new technique for breast cancer detection, based on the significant dielectric contrast between healthy and tumor tissues. Here we propose a procedure to fabricate, electromagnetically characterize and preserve realistic breast tissue-mimicking phantoms for testing mm-wave imaging prototypes. Low-cost, non-toxic and easy-to-produce mixtures made of sunflower oil, water and gelatin were prepared and their dielectric properties were for the first time measured in the (0.5–50) GHz frequency range using a coaxial probe kit. Different oil and gelatin percentages were tested. An alternative recipe based on a waste-oil hardener was also proposed. Finally, water and sunflower oil were investigated as preservation media. The mixtures electromagnetic properties were in good agreement with those of human breast ex vivo samples. By changing the ingredient concentrations or using different solidifying agents it was possible to mimic different tissue types. Besides, we show that sunflower oil represents an effective preservation medium for the developed materials. The first breast phantom mimicking a tumor mass into healthy tissues up to 50 GHz was also successfully fabricated. Results demonstrated the potential of the designed recipes to mimic breast tissues with different biological characteristics, preserving dielectric properties over time. Thus, this study represents a fundamental step towards the development of heterogeneous breast phantoms able to mimic the electromagnetic behavior of healthy and tumor tissues for mm-wave imaging applications.
Characterization of Dmrt3-Derived Neurons Suggest a Role within Locomotor Circuits

Neuronal networks within the spinal cord, collectively known as the central pattern generator (CPG), coordinate rhythmic movements underlying locomotion. The transcription factor doublesex and mab-3-related transcription factor 3 (DMRT3) is involved in the differentiation of the dorsal interneuron 6 class of spinal cord interneurons. In horses, a non-sense mutation in the Dmrt3 gene has major effects on gaiting ability, whereas mice lacking the Dmrt3 gene display impaired locomotor activity. Although the Dmrt3 gene is necessary for normal spinal network formation and function in mice, a direct role for Dmrt3-derived neurons in locomotor-related activities has not been demonstrated. Here we present the characteristics of the Dmrt3-derived spinal cord interneurons. Using transgenic mice of both sexes, we characterized interneurons labeled by their expression of Cre driven by the endogenous Dmrt3 promoter. We used molecular, retrograde tracing and electrophysiological techniques to examine the anatomical, morphological, and electrical properties of the Dmrt3-Cre neurons. We demonstrate that inhibitory Dmrt3-Cre neurons receive extensive synaptic inputs, innervate surrounding CPG neurons, intrinsically regulate CPG neuron's electrical activity, and are rhythmically active during fictive locomotion, bursting at frequencies independent to the ventral root output. The present study provides novel insights on the character of spinal Dmrt3-derived neurons, data demonstrating that these neurons participate in locomotor coordination. SIGNIFICANCE STATEMENT In this work, we provide evidence for a role of the Dmrt3 interneurons in spinal cord locomotor circuits as well as molecular and functional insights on the cellular and microcircuit level of the Dmrt3-expressing neurons in the spinal cord. Dmrt3 neurons provide the first example of an interneuron population displaying different oscillation frequencies. This study presents novel findings on an under-reported population of spinal cord neurons, which will aid in deciphering the locomotor network and will facilitate the design and development of therapeutics for spinal cord injury and motor disorders.
Compound motor action potential guided 240 seconds plus bonus freeze for safe and durable left atrial appendage isolation in patients with recurrent persistent atrial fibrillation: How to isolate the appendage with cryoballoon (the CMAP guided ICE‐B protocol)

Pulmonary vein isolation (PVI) is the cornerstone ablation strategy for treatment of atrial fibrillation (AF). Ablation outside the PVs is sometimes needed particularly in persistent or longstanding AF. This study reported left atrial appendage isolation (LAAI) using cryoballoon (CB) focusing on technical data and short‐term clinical follow‐up.
Fine-Mapping of Xq25.1–27.2 Shows Association of Early Childhood Caries with Genetic Variants Depending on Dietary Habits, Protecting Children Who Drink Milk before Going to Bed

Early childhood caries (ECC) is a chronic, infectious disease that affects the primary dentition of young children. It is the result of unequal contributions of risk factors and protective factors that influence the disease. The aim of this study was to assess if the X chromosome region previously linked to caries was associated with ECC. Two hundred and fifty-nine unrelated children with no chronic illnesses from 2 to 5 years of age who had no systemic fluoride consumption were evaluated using a cross-sectional design. Data on oral habits were obtained through a questionnaire, and caries experience data were collected by clinical examination. Twenty-three markers in ten genes were studied. Genotyping of the selected polymorphisms was carried out by real-time polymerase chain reaction. Regression analyses were performed comparing individuals with and without caries experience. Of 259 subjects, 123 were caries free. The markers in Xq25.1–27.2 were associated with ECC when children were using milk bottle for longer times (p = 0.01) and had more snacks over the course of a day (p = 0.05). Conversely, the markers in the X chromosome studied here were protective for ECC (p = 0.008) in children consuming milk before going to sleep. The genes located in the X chromosome possibly contribute to ECC and have an impact on ECC depending on the dietary habits.
Short article: Willingness to undergo colonoscopy with virtual reality instead of procedural sedation and analgesia

Objective This study explored the willingness of patients to start colonoscopy with virtual reality (VR) instead of procedural sedation and analgesia (PSA), as well as their motives and characteristics. There is a growing interest in colonoscopy without PSA. Offering VR as a distraction technique instead of PSA may increase the percentage of colonoscopies without PSA. Patients and methods A survey with demographic, colonoscopy-related and psychology-related questions was completed by 326 adults referred for colonoscopy with PSA. Results Overall, 25.7% reported to be willing to start with VR instead of PSA. Main reasons for this choice were receiving as little medication as possible, resuming daily life activities faster and participating in traffic independently afterwards. Logistic regression analysis showed that significant predictors of the willingness to use VR were male sex, higher educational level and absence of worries about the outcome of the colonoscopy. Conclusion If VR turns out to be effective in the future, present results may be useful to customize patient information to help patients choosing VR.
Typologies of Suicide: A Critical Literature Review

This review highlights proposed suicide typologies and identifies areas of future research. The current study is an illustrative, rather than exhaustive, qualitative review of theoretical and empirically derived typologies of suicide decedents. Theoretical and empirical typologies of suicide delineate between groups of suicide decedents based on individual, motivational, psychiatric, interpersonal, socio-demographic, and other variables. Certain core themes emerge across theoretical typologies including escape, aggression, intrapsychic pain, and relational concerns. Empirical typologies have identified unique patterns of life stressors, mental health history, health care utilization, and suicide method among suicide decedents. Future research should build on existing typological models of suicide to delineate when, and for whom, particular typologies of suicide may inform targeted prevention efforts. Researchers and clinicians should consider the characteristics and needs of particular high-risk groups when translating typological research into meaningful suicide prevention and intervention.
Novel β-lactam-β-lactamase inhibitor combinations: expectations for the treatment of carbapenem-resistant Gram-negative pathogens

ABSTRACT Introduction: The burden of antimicrobial resistance among Gram-negative bacteria is increasing and growing into a major threat of public health. Treatment options for carbapenem-resistant Enterobacteriaceae are limited and resistance rates to existing compounds are mounting. The pipeline includes only a small number of novel anti-infective agents in development or in the market with promising results against multidrug-resistant (MDR) Gram-negative. Areas covered: Herein the authors present the modern available knowledge regarding novel β-lactam-β-lactamase inhibitors, i.e. mechanisms of action, in vitro activity, current PK/PDs, clinical trials and clinical efficacy against MDR and XDR Gram-negatives, as well as toxicity issues. Expert opinion: Ceftazidime-avibactam and meropenem-vaborbactam are promising therapeutic options as both are active against Enterobacteriaceae producing ESBL, AmpC, and KPC, whereas only avibactam inhibits certain class D β-lactamases, mainly OXA-48. New drugs active against Gram-negative MDR isolates including imipenem/cilastatin with relebactam and avibactam combined with aztreonam or ceftaroline are in different stages of development. However, the disadvantage to be seriously considered by the clinician is that β-lactam/β-lactamase inhibitors are ineffective against metallo-β-lactamases (with the exception of aztreonam-avibactam) as well as Acinetobacter baumannii.
Friend-in-the-middle Attacks

In the ongoing arms race between spammers and the multimillion dollar anti-spam industry, the number of unsolicited e-mail messages (better known as “spam”) and phishing has increased heavily in the last decade. In this paper, we show that our novel friend-in-the-middle attack on social networking sites (SNSs) can be used to harvest social data in an automated fashion. This social data can then be exploited for large-scale attacks such as context-aware spam and social-phishing. We prove the feasibility of our attack exemplarily on Facebook and identify possible consequences based on a mathematical model and simulations. Alarmingly, all major SNSs are vulnerable to our attack as they fail to secure the network layer appropriately.
