Modifiable Risk Factors and Atrial Fibrillation

There has been increasing focus on the rising burden of atrial fibrillation (AF) since the turn of the millennium. The AF epidemic is projected not only to have an impact on morbidity and mortality, but also to result in increasing healthcare use and cost. Intensive research over the previous decades has improved our understanding of this complex arrhythmia while unraveling more knowledge gaps and inadequacies of current therapeutic options. Specifically, the advances in catheter ablation technology and strategies have not translated into significant gains in procedural success rates over recent years. Therefore, strategies aiming at lowering the risk of AF development and progression are urgently needed to curtail the AF epidemic and improve outcomes in affected individuals. Recent research has highlighted the potential beneficial effects of lifestyle and risk factor management for AF as upstream noninvasive therapy. The evidence supporting this treatment paradigm beyond routine clinical AF management argues for change in the delivery of care to patients who have this debilitating arrhythmia. In this review, we highlight the contributory role of risk factors to AF pathogenesis from both bench and bedside studies. Next, we discuss the rationale and potential benefits of risk factor modification for sinus rhythm maintenance. Last, we propose an integrated care model to incorporate risk factor modification as the fourth pillar of AF care in conjunction with established pillars of rate control, rhythm control, and anticoagulation therapy.
Depression: Current treatments with low-cost strategies

Depression has profound social, economic and personal consequences for the affected individual, and it shows no signs of abating in the general population. There are several treatment modalities available for this debilitating illness, however, effective as they are, these treatments have pitfalls. Antidepressants are the most common form of treatment for depression; they are relatively cheap and effective, but induce uncomfortable side-effects, some of which can be life threatening. These can include cardiotoxicity, weight gain, serotonin syndrome, sexual dysfunction, dry mouth and urinary retention. Electroconvulsive therapy has been used in the treatment of depression since the late 1930s and is effective particularly in severe depression. It is quick acting, but its use tend to evoke moral and ethical debates. Psychological therapies have been used since the 9th century and are effective and have little side-effects but they are relatively expensive and there is a long waiting list in the NHS for thes.
Evidence of Endoplasmic Reticulum Stress Mediating Cell Death in Transplanted Human Islets

A key limitation to the success of islet transplantation is islet cell exhaustion and cell death during islet isolation and following transplantation. Endoplasmic reticulum (ER) stress has been identified as an important mechanism in the development of β-cell dysfunction, cell death, and diabetes. This study investigated the role of ER stress in islet loss during human islet isolation and posttransplantation in a diabetic athymic mouse model. Islets were isolated from human organ donor pancreata using intraductal enzymatic dissociation and continuous density gradient purification. ER stress mediators were assessed by Western blot and by RT-PCR. Caspase-3 activity was quantified by a bioluminescent peptide cleavage assay. Normal and streptozotocin-treated diabetic nude mice were transplanted with 2,000 IEQ of human islets under the kidney capsule and the grafts were harvested 3 or 28 days after transplantation. The grafts were analyzed for the presence for ER stress signals by immunohistochemistry. Isolated islets demonstrated higher levels of ER chaperone Bip, ER stress mediators eIF2α, ATF, spliced XBP-1, and CHOP, and also ER stress-associated apoptotic signals like JNK, caspase-3/7, and cleaved PARP. Donor pancreatic tissue did not show expression of any of these ER stress mediators. After transplantation, low expression of only protective ER stress mediators was evident in the grafts from the normal recipients. In contrast, both protective and apoptotic ER stress mediators were highly expressed in the grafts of hyperglycemic mice. ER stress mediators were induced during islet isolation and may contribute to islet apoptosis and cell death. Islet isolation activates ER stress and apoptotic pathways in isolated islets. Hyperglycemia may prolong this ER stress signal in engrafted islets, converting the protective aspects of the ER stress response to a proapoptotic response and thus contribute to deterioration of β-cell function and survival.
What is the role of risk stratification for sudden death in the defibrillator era

Accurate and timely prediction of sudden cardiac death (SCD) is a necessary prerequisite for effective prevention and therapy. Although the largest numbers of SCD events occur in patients without overt heart disease, there are currently no tests that are of proven predictive value in this population. Efforts in risk stratification for SCD have focused primarily on predicting SCD in patients with known structural heart disease. Despite the ubiquity of tests that have been purported to predict SCD vulnerability in such patients, there is little consensus on which test, in addition to the left ventricular ejection fraction, should be used to select patients for implantable cardioverter defibrillators (ICDs). Effective therapy exists for SCD but it is costly and is associated with potential complications. Currently used strategies for selection of the best candidates for ICDs are imperfect and leave many high-risk patients unprotected. At the same time, some patients who receive ICDs will never develop ventricular tachyarrhythmia requiring ICD intervention. This article summarizes the current status and applicability of the non-invasive and invasive tests used for SCD risk assessment.
Avaliação de diferentes métodos de extração lipídica sobre a composição de ácidos graxos poliinsaturados em leite de vaca

SUMMARY. Different lipid extraction methods on fatty acids composition in cow milk. Comparative studies among 4 (four) different methods of total lipids extraction were carried out to evaluate the lipid extraction efficiency and fatty acids contents in cow milk. Total lipids extraction methods were Bligh e Dyer (BD), Folch et al. (FLS), Roese-Gottlieb (RG) and Gerber (GB). There were non-significant (p<0.05) difference, in total lipids content among the extraction methods. The smallest concentrations of omega-3 (n-3) fatty acids and polyunsaturated fatty acids (PUFA) were observed on method GE, possibly due degradation of PUFA immersed in sulfuric acid used during analysis of total lipids. The highest concentrations of n-3 PUFA were observed by BD method, especially to omega-3/omega-6 ratio and alpha-linolenic acid (LNA, 18:3n-3), eicosapentaenoic (EPA, 20:5n-3) and docosahexaenoic (DHA, 22:6n-3), significant differences were observed among the methods. The results demonstrate that the different extractions influenced decisively on quantitative fatty acids composition and evaluations indicated the methods BD as better and GE as the worst to polyunsaturated fatty acids determination.
African American Women and AIDS: Factors Influencing Risk and Reaction to HIV Disease

African American women represent the fastest growing group of individuals infected with HIV in the United States. Social and contextual influences on HIV risk vulnerability in this group are discussed, with particular emphasis on risk behaviors related to heterosexual contact and injection drug use. Social factors associated with the sex-ratio imbalance and low rates of condom use in the African American community are addressed, as are contextual influences related to environmental stress and psychosocial issues. We describe interventions that directly address both social and contextual influences on African American women’s risk behaviors. Finally, mental health and psychological concerns are presented as a framework for better understanding women’s reactions to HIV/AIDS and for developing comprehensive programs and services that better meet their needs.

Scientific Opinion on the risk of Phyllosticta citricarpa (Guignardia citricarpa) for the EU territory with identification and evaluation of risk reduction options

The Panel conducted a risk assessment of Phyllosticta citricarpa for the EU. P. citricarpa causes citrus black spot (CBS) and is absent from the EU. Under the scenario of absence of specific risk reduction options against P. citricarpa, the risk of entry of P. citricarpa was rated as likely for citrus plants for planting and citrus fruit with leaves, moderately likely for citrus fruit without leaves, unlikely for citrus leaves for cooking and very unlikely for Tahiti lime fruit without leaves. Establishment was rated as moderately likely because susceptible hosts are widely available and environmental conditions in many EU citrus-growing areas are suitable (with high uncertainty) for P. citricarpa ascospore production, dispersal and infection. Current fungicide treatments will not prevent establishment. Environmental favourability is increased by the use of sprinkler and micro-sprinkler irrigation in some EU citrus-growing locations. Spread with trade was rated as moderately likely. Model results indicate that CBS epidemics are most likely to develop in EU citrus-growing areas in late summer to early autumn and in some locations also in late spring to early summer. CBS is expected to affect mainly lemons and late-maturing sweet orange and mandarin varieties, with moderate negative consequences for the production of fresh fruit, but with environmental impact of additional fungicide treatments. Negative consequences would be minor for early-maturing citrus varieties and minimal for citrus for processing. Uncertainty concerning the consequences is high, mainly because of the lack of data on critical climate response parameters for the pathogen but also because information on impact in areas at the limits of the current distribution is scarce. Since eradication and containment are difficult, phytosanitary measures should focus on preventing entry. Current phytosanitary measures are evaluated to be effective, with the exception of pest-free production sites.
The CMYA5 gene confers risk for both schizophrenia and major depressive disorder in the Han Chinese population

Abstract Objectives. A recent genome-wide association study (GWAS) of the European population implicated the CMYA5 gene in schizophrenia. Previous functional studies showed that the CMYA5 protein can interact with DTNBP1 and PKA, providing further support for a role of CMYA5 in the pathogenesis of schizophrenia. However, this association requires additional validation in independent populations. Methods. To validate the association between CMYA5 and schizophrenia and major depressive disorder, we genotyped 16 SNPs within the CMYA5 gene and performed case–control studies in 1330 schizophrenia patients, 1045 patients with major depressive disorder, and 1235 normal controls. All patients were of Han Chinese origin. Results. rs6883197 and rs259127 were significantly associated with schizophrenia, and rs12514461, rs259127, and rs7343 were associated with major depressive disorder. Additionally, one risk haplotype of rs16877109–rs3828611 (G–G) was associated with both schizophrenia (P = 0.0000784, after correction) and major depressive disorder (P = 0.00230, after correction). Conclusions. Our findings support the idea that specific alleles and haplotype in the CMYA5 confer genetic risk for both schizophrenia and major depressive disorder in the Han Chinese population.
γδ T cells as a major source of IL-17 production during age-dependent RPE degeneration.

PURPOSE Chronic inflammation is a key factor contributing to the progression of age-related macular degeneration (AMD). The goals of the current study were to develop an improved mouse model with retinal pathologic features similar to those of AMD and to characterize the immunoreactive cells in the outer retina and choroid during degeneration of the retinal pigment epithelium (RPE). METHODS Mice deficient in nuclear erythroid 2-related factor 2 (Nrf2) at 12 months of age were fed a high-fat, cholesterol-rich diet for up to 16 weeks. Ocular phenotype was monitored by optical coherence tomography (OCT) and scanning laser ophthalmoscopy (SLO) in live animals, and was further validated by retinal histopathology. Immunofluorescence staining of either cryosections or RPE flat mounts was used to define immunoreactive cells. Flow cytometry analyses were further performed to define the subsets of intraocular T lymphocytes. RESULTS After 16 weeks on a high-fat (HF) diet, 58% of the eyes from Nrf2-/- mice had progression of retinal lesions. Major histocompatibility complex class II (MHC II)-positive microglia, FoxP3+ regulatory T cells (Tregs), and CD3+ IL-17-producing T cells were detected in either the retina or sub-RPE space. Flow cytometry analyses further revealed that most of the IL-17-producing cells were CD3+ CD4- TCRγδ+ cells. CONCLUSIONS The results suggest that the T cell-mediated immune responses played important roles in controlling the progression of AMD-like phenotype in Nrf2-deficient mice.
A Contextual Approach to Privacy Online

Abstract Recent media revelations have demonstrated the extent of third-party tracking and monitoring online, much of it spurred by data aggregation, profiling, and selective targeting. How to protect privacy online is a frequent question in public discourse and has reignited the interest of government actors. In the United States, notice-and-consent remains the fallback approach in online privacy policies, despite its weaknesses. This essay presents an alternative approach, rooted in the theory of contextual integrity. Proposals to improve and fortify notice-and-consent, such as clearer privacy policies and fairer information practices, will not overcome a fundamental flaw in the model, namely, its assumption that individuals can understand all facts relevant to true choice at the moment of pair-wise contracting between individuals and data gatherers. Instead, we must articulate a backdrop of context-specific substantive norms that constrain what information websites can collect, with whom they can share it, and under what conditions it can be shared. In developing this approach, the paper warns that the current bias in conceiving of the Net as a predominantly commercial enterprise seriously limits the privacy agenda.
A Scalable Multi-Target Tracking Algorithm for Wireless Sensor Networks

Multi-target tracking is a representative real-time application of sensor networks as it exhibits different aspects of sensor networks such as event detection, sensor information fusion, multihop communication, sensor management, and real-time decision making. The task of tracking multiple objects in a wireless sensor network is challenging due to constraints on a sensor node such as short communication and sensing ranges, a limited amount of memory, and limited computational power. In addition, since a sensor network surveillance system needs to operate autonomously without human operators, it requires an autonomous real-time tracking algorithm which can track an unknown number of targets. In this paper, we develop a scalable real-time multi-target tracking algorithm that is autonomous and robust against transmission failures, communication delays, and sensor localization error. The algorithm is based on a rigorous probabilistic model and an approximation scheme for the optimal Bayesian filter. In particular, an extensive simulation study shows that there is no performance loss up to an average localization error of 0.7 times the separation between sensors and the algorithm tolerates up to 50% lost-to-total packet ratio and 90% delayed-to-total packet ratio. The proposed algorithm has been successfully applied to real-time multi-target tracking problems using wireless sensor networks.
Evaluation of retained testes in adolescent girls and women with complete androgen insensitivity syndrome.

PURPOSE To evaluate the magnetic resonance (MR) imaging appearance of the testes in women with complete androgen insensitivity syndrome (CAIS), including any benign or malignant changes. MATERIALS AND METHODS This was a retrospective review of the testicular MR images and histologic reports from 25 patients with CAIS who chose to retain their testes beyond age 16 years and who were imaged between January 2004 and December 2010. Ethical approval was obtained, and informed consent was obtained from each subject to review the medical records, images, and histologic slides and reports. Imaging and histologic findings were compared. RESULTS Twelve patients (mean age, 24 years; age range, 18-39 years) retained their testes and 13 (mean age, 22 years; age range, 17-37 years) eventually underwent gonadectomy. Review of the MR images showed that testicular parenchyma was heterogeneous in 30 of 46 testes (65%). The most common changes on MR images included simple-looking paratesticular cysts (34 of 46 testes, 74%) and low-signal-intensity, well-defined Sertoli cell adenomas (26 of 46 testes, 56%). Correlation of the histologic and MR imaging findings showed that MR imaging could correctly depict the presence or absence of Sertoli cell adenomas in 19 of 23 testes (83%). Paratesticular cysts were correctly detected in 22 of 23 testes (96%). Microscopic examination showed that the testes were composed of atrophic seminiferous tubules, whereas germ cells were found in 13 of 26 testes (50%). All paratesticular cysts were confirmed to be benign; however, a focus of intratubular germ cell neoplasia was found in a Sertoli cell adenoma. Premalignant foci were detected in three patients, two with intratubular germ cell neoplasia and one with sex cord tumor with annular tubules. No invasive cancers were found. CONCLUSION MR imaging is accurate in the detection of testicular changes, including paratesticular cysts and Sertoli cell adenomas. Although these changes are usually benign, Sertoli adenomas can sometimes harbor premalignant lesions. MR imaging cannot depict premalignant changes; therefore, the standard of care for patients with CAIS should remain gonadectomy after puberty.
A Community’s Awareness and Perceptions of Genomic Medicine

Background: Focus groups were conducted in a mid-sized community to explore community members’ awareness and perceptions of genomic medicine and identify effective methods to educate the public about this topic. Methods: Thirteen focus groups were conducted with a demographically representative pool of 121 participants using a semi-structured interview guide. Transcripts were analyzed through a computer assisted approach with Atlas TI consisting of coding, categorizing, comparing, and contrasting relevant data. Results: Identified categories were organized into 6 main themes, which were similar across the groups and included: a lack of awareness, perceived benefits, concerns about genomic medicine, reasons for poor health related behavior, the potential impact of genetic information on health behavior, and the best ways to educate the community. Common concerns included lack of affordability, unanticipated physical harm, mistrust of the government and researchers, downstream effects like overpopulation, playing God/disturbing the natural order, lack of regulations, loss of privacy, genetic discrimination, and moral dilemmas posed by genetic engineering, cloning, choosing traits, and abortions resulting from genetic information. Participants also discussed ways to educate the community. Conclusions: While individuals recognized that diseases run in families, personal experience was a driving factor in participants’ level of knowledge. Many expressed optimism about genomic medicine. However, the lack of depth in responses and their misconceptions reflect a deficiency of knowledge, which along with their personal, moral, and global concerns could impede acceptance and utilization of genomic medicine. Many community members are receptive to learning more about genomic medicine, and many of their concerns and misconceptions can be addressed through a well designed education strategy.
Exploring the Role of Wealth and Religion on the Ownership of Captive Lemurs in Madagascar Using Qualitative and Quantitative Data

Primates are kept as pets for various reasons including as indicators of wealth. Ownership of primates can also be influenced by religion. In Madagascar, thousands of lemurs are kept as pets, but the roles of wealth and religion in the ownership of captive lemurs have not been explored. We use quantitative and qualitative data to examine these aspects of ownership. Quantitative data were collected (July to August 2016) in households (n = 596) of 12 urban and rural towns in Madagascar using semi-structured interviews. International standards for research ethics were followed. Research was approved by an ethics oversight committee. We also opportunistically visited 13 religious facilities. Qualitative data were used to frame the context of the quantitative data. We found that pet lemur owners do not speak about their lemurs as a symbol of wealth, but non-owners associate pet lemurs with wealth. Therefore, status/wealth may be a motivating factor in the ownership of pet lemurs. We also found evidence that Catholic entities in Madagascar sometimes take in captive lemurs when the owner can no longer care for the animal (being viewed as animal-friendly institutions). However, we did not find evidence of religion (institutional or traditional) influencing the ownership of pet lemurs.
Assessment of Chemical Factors in Relation to Child Hyperactivity

A questionnaire evaluation of 486 hyperactive children (HA) (82% boys, aged 7-13 years and 18% girls, aged 8-13 years) showed that more than 60% of cases reported a positive behavioural response (i.e. increased problems) in relation to consuming or being exposed to synthetic colourings and flavourings, food and beverage preservatives, cow's milk and associated products, chemical detergents and perfume. In contrast, 172 sex- and age-matched control children (C) reported only 12% of cases responding to synthetic colourings and flavourings and chemical solvents. The main health problems reported by the 96% of hyperactive children affected by synthetic colourings and flavourings were persistent thirst problems, the development of eczema, ear and/or chest infections, and the production of excessive amounts of catarrh. Trace element measurements undertaken by inductively coupled plasma mass spectrometry showed that a low zinc and iron status is associated with hyperactive children when compared with control chi.
