    In this paper, we evaluate the level of knowledge and awareness among 120 radiology personnel working in 7 public hospitals in Johor, Malaysia, concerning Computed Tomography (CT) technology and radiation doses based on a set of questionnaires. Subjects were divided into two groups (Medical profession (Med, n=32) and Allied health profession (AH, n=88). The questionnaires are addressed: (1) demographic data (2) relative radiation dose and (3) knowledge of current CT technology. One-third of respondents from both groups were able to estimate relative radiation dose for routine CT examinations. 68% of the allied health profession personnel knew of the Malaysia regulations entitled ‘Basic Safety Standard (BSS) 2010’, although notably 80% of them had previously attended a radiation protection course. No significant difference (p < 0.05) in mean scores of CT technology knowledge detected between the two groups, with the medical professions producing a mean score of (26.7 ± 2.7) and the allied health professions a mean score of (25.2 ± 4.3). This study points to considerable variation among the respondents concerning their understanding of knowledge and awareness of risks of radiation and CT optimization techniques.

    Background Nearly 80 million people in the U.S. are currently infected with at least one of two strains of human papillomavirus (HPV), which is associated with 70% of cervical cancers. Greater cervical cancer mortality has been observed among women of lower SES and those living in rural, versus urban, areas. African American and Hispanic women are significantly more likely to die from cervical cancer than non-Hispanic white women. Purpose To assess current population awareness of and knowledge about HPV and the HPV vaccine, as well as the contribution of sociodemographic characteristics to disparities in HPV awareness and knowledge. Methods Cross-sectional data were obtained from the National Cancer Institute’s 2013 Health Information National Trends Survey (HINTS; N=3,185). Multivariable logistic regression was employed to identify gaps in awareness and knowledge by sex, education, income, race/ethnicity, geographic area, and other important sociodemographic characteristics. Analyses were conducted in 2014. Results Sixty-eight percent of Americans had heard of HPV and the HPV vaccine. Consistent with the Knowledge Gap Hypothesis, awareness and knowledge were patterned by sex, age, education, and other important sociodemographic factors. Those in rural areas were less likely than those in urban areas to know that HPV causes cervical cancer. Less than 5% of Americans were aware that HPV often clears on its own without treatment. Conclusions Although awareness and knowledge of HPV is increasing, there are opportunities to target communication with populations for whom knowledge gaps currently exist, in order to promote dialogue about the vaccine among patients and their providers.

    AIM: To investigate grandparent’s knowledge and awareness about the oral health of their grandchildren. METHODS: Grandparents accompanying patients aged 4-8 years, who were living with their grandchildren and caring for them for a major part of the day, when both their parents were at work were included in the study. A 20-item questionnaire covering socio-demographic characteristics, dietary and oral hygiene practices was distributed to them. The sample comprised of 200 grandparents (59 males, 141 females). χ2 analysis and Gamma test of symmetrical measures were applied to assess responses across respondent gender and level of education. RESULTS: Oral health related awareness was found to be low among grandparents. In most questions asked, grandparents with a higher level of education exhibited a better knowledge about children's oral health. Level of awareness was not related to their gender. CONCLUSION: Oral hygiene and dietary habits are established during childhood. There is a great need for dental education of grandparents as they serve as role models for young children.

    There have been numerous efforts to create comprehensive databases from multiple sources to monitor the dynamics of public health and most specifically to detect the potential threats of bioterrorism before widespread dissemination. But there are not many evidences for the assertion that these systems are timely and dependable, or can reliably identify man made from natural incident. One must evaluate the value of so called 'syndromic surveillance systems' along with the costs involved in design, development, implementation and maintenance of such systems and the costs involved in investigation of the inevitable false alarms1. In this article we will introduce a new perspective to the problem domain with a shift in paradigm from 'surveillance' toward 'awareness'. As we conceptualize a rather different approach to tackle the problem, we will introduce a different methodology in application of information science, computer science, cognitive science and human-computer interaction concepts in design and development of so called 'public health situation awareness systems'. We will share some of our design and implementation concepts for the prototype system that is under development in the Center for Biosecurity and Public Health Informatics Research, in the University of Texas Health Science Center at Houston. The system is based on a knowledgebase containing ontologies with different layers of abstraction, from multiple domains, that provide the context for information integration, knowledge discovery, interactive data mining, information visualization, information sharing and communications. The modular design of the knowledgebase and its knowledge representation formalism enables incremental evolution of the system from a partial system to a comprehensive knowledgebase of 'public health situation awareness' as it acquires new knowledge through interactions with domain experts or automatic discovery of new knowledge.

    Risk assessment is of importance for the reduction of natural disasters. By utilizing the risk information such as producing shake maps or tsunami hazard maps, people can learn what kind of natural hazards they have to deal with. Japanese government takes it as an effective strategy in mitigating earthquake disaster to transfer the basic knowledge of the tectonic background of Japan and of the latest research results. In fact, the Headquarters for Earthquake Research Promotion describes in their webpage that their basic concept is: to transfer the knowledge of research results such as long-term evaluation of large earthquake occurrence to the public, so that people will be aware and conscious of the existing risks, and then they take action to mitigate earthquake disaster. On the other hand, it goes without saying that there always exists a constant risk of earthquake disaster in Japan and every single person living in this earthquake prone country knows that. Moreover, residents know what will happen when a big earthquake occurs such as collapse of houses or tsunamis unlike cases for unknown infectious diseases. Thus they do not have to wait for the government's releasing latest research results of long-term evaluation and possibility of large earthquake occurrence to take action to mitigate disaster. Yet, people die from earthquakes of magnitude-7 class almost every year in Japan, and the causes of death are very common ones such as collapse of houses, falloff of furniture, fire or tsunamis. This fact tells us that the knowledge itself will not give serious awareness of earthquake risks or not motivate people to take action for disaster prevention. We have to have another look at the personnel risk management of earthquake disaster, for the concept of 3-steps; giving knowledge, giving awareness, and taking action would not work as expected. To examine this, we conducted experiments to see if knowledge of earthquake science helps people to be aware the risks or to

    We report results from two studies on the underlying dimensions of morphological awareness and vocabulary knowledge in elementary-aged children. In Study 1, 99 fourth-grade students were given multiple measures of morphological awareness and vocabulary. A single factor accounted for individual differences in all morphology and vocabulary assessments. Study 2 extended these results by giving 90 eighth-grade students expanded measures of vocabulary and morphology that assessed (a) definitional knowledge, (b) usage, (c) relational knowledge, and (d) knowledge of morphological variants, with each potential aspect of knowledge assessed using an identical set of 23 words to control for differential knowledge of specific vocabulary items. Results indicated that a single-factor model that encompassed morphological and vocabulary knowledge provided the best fit to the data. Finally, explanatory item response modeling was used to investigate sources of variance in the vocabulary and morphological awareness tasks we administered. Implications for assessment and instruction are discussed. PMID:26273128

    2015-01-01

    The aim of this study is to examine the developmental relationship between compounding awareness and vocabulary knowledge from grades 1 to 2 in Chinese children. In this study, 149 Chinese children were tested on compounding awareness and vocabulary knowledge from Time 1 to Time 4, with non-verbal IQ, working memory, phonological awareness, orthographical awareness, and rapid automatized naming at Time 1 as control variables. Latent growth modeling was conducted to analyze the data. Univariate models separately calculated children's initial levels and growth rates in compounding awareness and vocabulary knowledge. Bivariate model was used to examine the direction of the developmental relationships between the two variables with other cognitive and linguistic variables and the autoregression controlled. The results demonstrated that the initial level of compounding awareness predicted the growth rate of vocabulary knowledge, and the reverse relation was also found, after controlling for other cognitive and linguistic variables and the autoregression. The results suggested a reciprocal developmental relationship between children's compounding awareness and vocabulary knowledge for Chinese children, a finding that informs current models of the relationship between morphological awareness and vocabulary knowledge.

    2012-01-01

    Pancreatic cancer is the fourth leading cause of cancer death with a median survival of 6 months and a dismal 5-year survival rate of 3–5%. The development and progression of pancreatic cancer are caused by the activation of oncogenes, the inactivation of tumor suppressor genes, and the deregulation of many signaling pathways. Therefore, the strategies targeting these molecules as well as their downstream signaling could be promising for the prevention and treatment of pancreatic cancer. However, although targeted therapies for pancreatic cancer have yielded encouraging results in vitro and in animal models, these findings have not been translated into improved outcomes in clinical trials. This failure is due to an incomplete understanding of the biology of pancreatic cancer and to the selection of poorly efficient or imperfectly targeted agents. In this review, we will critically present the current knowledge regarding the molecular, biochemical, clinical, and therapeutic aspects of pancreatic cancer. PMID:22655256

  6. Family physicians' awareness and knowledge of the Genetic Information Non-Discrimination Act (GINA).

    PubMed

    2012-04-01

    Historically, physicians have expressed concern about their patients' risk of genetic discrimination, which has acted as a barrier to uptake of genetic services. The Genetic Information Nondiscrimination Act of 2008 (GINA) is intended to protect patients against employer and health insurance discrimination. Physicians' awareness and knowledge of GINA has yet to be evaluated. In 2009, we mailed surveys to 1500 randomly selected members of the American Academy of Family Physicians. Questions measured physicians' current knowledge of GINA and their level of concern for genetic discrimination. In total, 401 physicians completed the survey (response rate 26.9%). Approximately half (54.5%) of physicians had no awareness of GINA. Of physicians who reported basic knowledge of GINA, the majority were aware of the protections offered for group health insurance (92.7%), private health insurance (82.9%), and employment (70.7%). Fewer physicians were aware of GINA's limitations regarding life insurance (53.7%) and long-term care insurance (58.8%). Physicians demonstrated highest levels of concern for health insurance, life insurance, and long-term care insurance discrimination, with less concern for employer and family/social discrimination. Level of concern for the risk of genetic discrimination did not correlate significantly with awareness of GINA. Approximately 17 months after GINA was signed into federal law, physicians' knowledge remained limited regarding the existence of this legislation and relevant details. Physicians who are aware of GINA continue to have significant concerns regarding the risk of genetic discrimination. This study reveals the need to further educate physicians about the existence of GINA and the protections offered.

  16. Practical robotic self-awareness and self-knowledge

    NASA Astrophysics Data System (ADS)

    Gage, Douglas W.

    2011-05-01

    The functional software components of an autonomous robotic system express behavior via commands to its actuators, based on processed inputs from its sensors; we propose an additional set of "cognitive" capabilities for robotic systems of all types, based on the comprehensive logging of all available data, including sensor inputs, behavioral states, and outputs sent to actuators. A robot should maintain a "sense" of its own (piecewise) continuous existence through time and space; it should in some sense "get a life," providing a level of self-awareness and self-knowledge. Self-awareness includes the ability to survive and work through unexpected power glitches while executing a task or mission. Selfknowledge includes an extensive world model including a model of self and the purpose context in which it is operating (deontics). Our system must support proactive self-test, monitoring, and calibration, and maintain a "personal" health/repair history, supporting system test and evaluation by continuously measuring performance throughout the entire product lifecycle. It will include episodic memory, and a system "lifelog," and will also participate in multiple modes of Human Robotic interaction (HRI).

    2015-01-01

    Although only a single serotype of hepatitis E virus (HEV), the causative agent of hepatitis E, has been identified, there is great genetic variation among the different HEV isolates reported. There are at least four major recognized genotypes of HEV: genotypes 1 and 2 are mainly restricted to humans and linked to epidemic outbreaks in nonindustrialized countries, whereas genotypes 3 and 4 are zoonotic in both developing and industrialized countries. Besides human strains, genotype 3 and 4 strains of HEV have been genetically characterized from swine, sika deer, mongooses, sheep, and rabbits. Currently, there are approximately 11,000 human and animal sequences of HEV available at the International Nucleotide Sequence Database Collaboration. HEV is the major cause of waterborne outbreaks of hepatitis in areas of poor sanitation. Additionally, it is responsible for sporadic cases of viral hepatitis in not only endemic but industrialized countries as well. Transmission of HEV occurs predominantly by the fecal-oral route, although parenteral and perinatal routes have been reported. HEV infection develops in most individuals as a self-limiting, acute, icteric hepatitis; with mortality rates around 1%. However, some affected individuals will develop fulminant hepatic failure, a serious condition that is frequently fatal without a liver transplant. This complication is particularly common when the infection occurs in pregnant women, where mortality rates rise dramatically to up to 25%. Among the preventive measures available to avoid HEV infection, two separate subunit vaccines containing recombinant truncated capsid proteins of HEV have been shown to be highly effective in the prevention of disease. One of them, HEV 239, was approved in China, and its commercialization by Innovax began in November 2012 under the name Hecolin®. PMID:26355220

    Bmore » ackground . Congenital cytomegalovirus (CMV) infection is a leading cause of disabilities in children, yet the general public appears to have little awareness of CMV. Methods . Women were surveyed about newborn infections at 7 different geographic locations. Results . Of the 643 women surveyed, 142 ( 22 % ) had heard of congenital CMV. Awareness increased with increasing levels of education ( P < .0001 ). Women who had worked as a healthcare professional had a higher prevalence of awareness of CMV than had other women ( 56 % versus 16 % , P < .0001 ). Women who were aware of CMV were most likely to have heard about it from a healthcare provider ( 54 % ), but most could not correctly identify modes of CMV transmission or prevention. Among common causes of birth defects and childhood illnesses, women's awareness of CMV ranked last. Conclusion . Despite its large public health burden, few women had heard of congenital CMV, and even fewer were aware of prevention strategies.« less

    This case-control study aimed to assess tuberculosis (TB) awareness and its associated sociodemographic characteristics in Gezira, Sudan. New smear-positive TB patients registered in Gezira in 2010 (n = 425) and age-matched controls who attended the same health facilities for other reasons (n = 850) formed the study sample. Awareness was measured using a modified standard World Health Organization TB knowledge, attitude and practice instrument. There was no significant difference between TB cases and the controls in overall levels of TB awareness. About two-thirds of TB cases and controls had good TB awareness. Respondents' sex was associated with awareness among the controls. Age, level of education, type of residence and type of occupation were significantly associated with TB awareness, whereas marital status had no effect. The good level of TB awareness found among TB cases and controls is a baseline for further TB awareness-raising among the Gezira population.

    In response to current and projected demographic changes in the United States, many dental schools have taken steps to increase the cultural competence of their students through various educational methods. The aim of this study was to evaluate the effectiveness of the cultural competency curriculum at Boston University Henry M. Goldman School of Dental Medicine (GSDM). The curriculum was evaluated using a pre and post design, utilizing an instrument developed for pharmacy students and modified for dental students. The questionnaire was comprised of 11 items designed to assess changes in students' awareness, knowledge, and skills in providing culturally competent care. Data were collected for two classes of second-year DMD students and first-year Advanced Standing students. The total number of returned surveys was 485, for a response rate of 79.5%. The students' post-curriculum mean scores were all higher than their pre-curriculum scores for overall cultural competence (pre 26.5±6.3 to post 29.8±7.2) and for individual subscores on awareness (pre 5.3±1.4 to post 5.5±1.5), knowledge (pre 7.2±1.9 to post 8.1±2.1), and skills (pre 14.1±4.4 to post 16.2±4.4). The improvements on all scores were statistically significant (p<0.0001), with the exception of the awareness component. This evaluation suggests that the cultural competency curriculum at GSDM has been effective in producing improvements in these students' cultural competence in the domains of knowledge and skills.

    Objectives: To examine the awareness, knowledge, and attitudes regarding vitamin D and its sources among Saudi Arabian children. Methods: One hundred patients (vitamin D-deficient children) and 100 healthy children participated in the study. Participants were interviewed separately on topics including their awareness, knowledge, and attitudes regarding vitamin D using multiple-choice, and short-answer questions. This prospective, cross-sectional study was performed on children and adolescents between January 2011 and December 2011 at the Security Forces Hospital, Riyadh, Saudi Arabia. Results: Only 28% were aware of the sources of vitamin D, while 64% of healthy subjects were aware. Similarly, only 50% of patients and their parents knew of the health benefits of vitamin D, while 70% of healthy subjects had knowledge. Hence, our findings agree with previous findings that low levels of awareness and knowledge regarding vitamin D and its sources persist. Conclusion: Most vitamin D deficient cases were unaware of vitamin D sources. However, half of the patient/parents were aware of benefits of vitamin D. Hence, we recommend that an improved campaign for awareness, knowledge, and attitudes regarding vitamin D and its sources are needed. PMID:27146624

    Accurate knowledge about human Papillomavirus (HPV) and its link to cervical cancer is essential for women to understand and make use of cervical cancer prevention and detection opportunities. This study was the first to survey awareness and knowledge of HPV in a population of Canadian Inuit. The objectives of this study were to assess the level of awareness and knowledge of Inuit women in Nunavik, Quebec, Canada, about HPV infection and its relation to cervical cancer and to study correlates of this awareness. A cross-sectional survey design was used. Women were recruited through convenience sampling at two recruitment sites in Ungava Bay from March 2008 to June 2009. Questionnaires were completed by 175 women aged 18-63. Thirty one percentage reported that they had heard of HPV. Of the women who had heard of HPV, 53% knew that HPV causes cervical cancer. The level of HPV awareness was not found to vary with participants' age. Awareness of HPV was found to be associated with greater or equal to 13 years of education (OR = 4.4, 95%: 1.3-15.1) and knowing someone with cervical cancer (OR = 3.6, 95%: 1.4-8.9). Despite the high prevalence of HPV and incidence of cervical cancer in Inuit populations, there is a low level of knowledge in this population. The lack of awareness and knowledge and misconceptions found in this study has been consistently found in other non-Indigenous populations.

    The response of roots to a moisture gradient has been reexamined, and positive hydrotropism has been demonstrated in recent years. Agravitropic roots of a pea mutant have contributed to the studies on hydrotropism. The kinetics of hydrotropic curvature, interactions between hydrotropism and gravitropism, moisture gradients required for the induction of hydrotropism, the sensing site for moisture gradients, characteristics of hydrotropic signal and differential growth, and calcium involvement in signal transduction have been subjects of these studies. This review summarizes the current state of our knowledge on hydrotropism in roots. PMID:11541137

    Background Ovarian cancer is the most lethal gynecologic disease in the United States, with more women dying from this cancer than all gynecological cancers combined. Ovarian cancer has been termed the “silent killer” because some patients do not show clear symptoms at an early stage. Currently, there is a lack of approved and effective early diagnostic tools for ovarian cancer. There is also an apparent severe knowledge gap of ovarian cancer in general and of its indicative symptoms among both public and many health professionals. These factors have significantly contributed to the late stage diagnosis of most ovarian cancer patients (63% are diagnosed at Stage III or above), where the 5-year survival rate is less than 30%. The paucity of knowledge concerning ovarian cancer in the United States is unknown. Methods The present investigation examined current public awareness and knowledge about ovarian cancer. The study implemented design strategies to develop an unbiased survey with quality control measures, including the modern application of multiple statistical analyses. The survey assessed a reasonable proxy of the US population by crowdsourcing participants through the online task marketplace Amazon Mechanical Turk, at a highly condensed rate of cost and time compared to traditional recruitment methods. Conclusion Knowledge of ovarian cancer was compared to that of breast cancer using repeated measures, bias control and other quality control measures in the survey design. Analyses included multinomial logistic regression and categorical data analysis procedures such as correspondence analysis, among other statistics. We confirmed the relatively poor public knowledge of ovarian cancer among the US population. The simple, yet novel design should set an example for designing surveys to obtain quality data via Amazon Mechanical Turk with the associated analyses. PMID:24465580

    Kangaroo Mother Intervention (KMI) started in 1978 in Colombia as a way of dealing with overcrowding and scarcity of resources in hospitals caring for low birth weight infants. Currently the intervention comprises three components: kangaroo position (skin-to-skin contact), kangaroo nutrition (exclusive or nearly exclusive breast-feeding), and kangaroo discharge policies (early discharge in kangaroo position regardless of weight or gestational age). Different authors have adopted and adapted diverse components of the KMI to suit the particular needs of their parents. We discuss different modalities of kangaroo care reported in developed and in developing countries and also describe in some detail the components of the whole KMI program. In addition, results from a systematic review of kangaroo-related papers published in English between 1991 and 1995 are provided, together with a summary of current knowledge (evidence-based) and research needs.

Due to the fact that male-based contraceptive methods are mostly represented by condoms and vasectomy, researchers are working on the new solutions, which could let the men be more involved in a conscious family planning. In this review we will present the current state of knowledge on this subject. There is a lot going on in the field of hormonal contraception. Studies including testosterone, progestins, synthetic androgens and other derivatives are on a different stages of clinical trials and mostly demonstrate high efficacy rates. Recent discovers of Izumo and Juno proteins, essential for the fertilization process, give hope for an easily reversible, non-hormonal method. Researchers are also trying to interfere with the process of spermatogenesis using BRDT inhibitor - JQ1, or neutralize the sperm by injecting styrene maleic anhydride (SMA) into the lumen of the vas deferens. The other studies explore processes involved in proper sperm motility. A vaccine which induces an immune response to the reproductive system is also an interesting method. The latest research use ultrasound waves and mechanical device which blocks the patency of vas deferens. The aim of the study current state of knowledge male contraception.

    African Americans are the most affected by HIV/AIDS. Both males and females continue to be disproportionately affected by HIV/AIDS. They are often drug users or participate in street/drug subculture. Recent weather disasters have required identification of knowledge, beliefs, conduct norms and behavior patterns that are HIV/AIDS risk factors for disaster survivors. This paper examines patterns of behavior and common practices related to HIV among disaster survivors. Study background Data for this paper come from a three year renewal project which focused upon the processes by which illicit drug markets were reformulated after disasters and practices of risk behaviors for HIV/AIDS. Hurricanes Katrina, Gustav and Ike presented the opportunity to examine the impact of disasters upon risky behavior among illicit drug users and sellers. Methods From 2010-2013 ethnographic study was conducted in New Orleans, Louisiana, Houston and Galveston, Texas. Staff completed in-depth interviews with 132 focal respondents of drug users and sellers. There were 57 focus groups with 243 focus group participants; 350 drug using/selling respondents completed a survey protocol (CAPI), organized around their experiences during the hurricanes. Results In both cities respondents displayed knowledge about HIV, modes of transmission and knew that HIV infection can lead to AIDS. Knowledge about time between exposure and infection was mostly imprecise. Most respondents reported they had been tested for HIV multiple times. A large number of participants reported learning about HIV in school, older respondents (mid-40s to 60) reported their knowledge came from television or the streets. Participants expressed fatalistic attitudes toward HIV, believing the virus was fatal even with medication. Conclusion With the increase of disasters, more attention needs to be placed upon programs focused on drug consumers. Schools, clinics, public information sources, i.e., TV and radio can make understanding

    In the 1970s several states in the Great Lakes region became concerned about mercury contamination in lakes and rivers and were the first to issue local fish consumption advisories. In 2001, the Food and Drug Administration (FDA) advised pregnant women, nursing mothers, young children, and women who may become pregnant not to consume shark, swordfish, king mackerel, and tilefish and recommended that these women not exceed 12 ounces of other fish per week. In 2004, FDA reissued this advice jointly with the U.S. Environmental Protection Agency (EPA) and modified it slightly to provide information about consumption of canned tuna and more details about consumption of recreationally caught fish. Though several studies have examined consumers' awareness of the joint FDA and EPA advisory as well as different state advisories, few used representative data. We examined the changes in awareness and knowledge of mercury as a problem in fish using the pooled nationally representative 2001 and 2006 Food Safety Surveys (FSS) with sample sizes of 4482 in 2001 and 2275 in 2006. Our results indicated an increase in consumers' awareness of mercury as a problem in fish (69% in 2001 to 80% in 2006, p<.001). In our regression models, we found that in both years, parents having children less than 5 years of age were more aware of mercury in fish and knowledgeable about the information contained in the national advisories about mercury in fish (p<.01) than other adults. In both 2001 and 2006, women of childbearing age (aged 18-45) were less aware and knowledgeable about this information than other women. However, women of all age groups had larger gains in awareness and knowledge than their male counterparts during this time. Participants' race, education, income, region, fish preparation experiences, having a foodborne illness in the past year, and risk perceptions about the safety of food were significant predictors of their awareness and knowledge. - Research highlights: {yields} We

  9. Assessing awareness, interest, and knowledge of fractal geometry among secondary mathematics teachers in the United States and China

    Chen, Suanrong

    Fractal geometry has gained great attention from mathematicians and scientists in the past three decades (Fraboni & Moller, 2008). As a new geometry language and subject, fractal geometry has significant value in teaching and learning secondary mathematics. The present study focused on investigating the current state of mathematics teachers' awareness, interest, and knowledge of fractal geometry in the United States (U.S.) and China, as well as the factors that influence them. The instrument of the study included a survey and a test designed by the researcher and validated by five experts. The results of the study indicated that secondary math teachers in the U.S. and China had very low levels of awareness of fractals and lack the knowledge and skills of solving fractal problems, but they had a higher level of interest in fractals related to classroom teaching and professional development as compared with their levels of awareness. Furthermore, the results of this study indicated that the factor 'experience of learning fractals' had the most positive effect on the average score of awareness. The factor nationality (U.S.) had the most positive effect on the average score of interest. The factor nationality (U.S.) had the most negative effect on the average score of knowledge.

    Infertility is a condition that occurs very frequently and understanding what defines normal fertility is crucial to helping patients. Causes of infertility are numerous and the treatment often does not lead to desired pregnancy especially when there is a lack of functional gametes. In humans, the primordial germ cell (PGC) is the primary undifferentiated stem cell type that will differentiate towards gametes: spermatozoa or oocytes. With the development of stem cell biology and differentiation protocols, PGC can be obtained from pluripotent stem cells providing a new therapeutic possibility to treat infertile couples. Recent studies demonstrated that viable mouse pups could be obtained from in vitro differentiated stem cells suggesting that translation of these results to human is closer. Therefore, the aim of this review is to summarize current knowledge about PGC indicating the perspective of their use in both research and medical application for the treatment of infertility.

    Background Incorrect knowledge of laws may affect how women enter the health system or seek services, and it likely contributes to the disconnect between official laws and practical applications of the laws that influence women’s access to safe, legal abortion services. Objective To provide a synthesis of evidence of women’s awareness and knowledge of the legal status of abortion in their country, and the accuracy of women’s knowledge on specific legal grounds and restrictions outlined in a country’s abortion law. Methods A systematic search was carried for articles published between 1980–2015. Quantitative, mixed-method data collection, and objectives related to women’s awareness or knowledge of the abortion law was included. Full texts were assessed, and data extraction done by a single reviewer. Final inclusion for analysis was assessed by two reviewers. The results were synthesised into tables, using narrative synthesis. Results Of the original 3,126 articles, and 16 hand searched citations, 24 studies were included for analysis. Women’s correct general awareness and knowledge of the legal status was less than 50% in nine studies. In six studies, knowledge of legalization/liberalisation ranged between 32.3% - 68.2%. Correct knowledge of abortion on the grounds of rape ranged from 12.8% – 98%, while in the case of incest, ranged from 9.8% - 64.5%. Abortion on the grounds of fetal impairment and gestational limits, varied widely from 7% - 94% and 0% - 89.5% respectively. Conclusion This systematic review synthesizes literature on women’s awareness and knowledge of the abortion law in their own context. The findings show that correct general awareness and knowledge of the abortion law and legal grounds and restrictions amongst women was limited, even in countries where the laws were liberal. Thus, interventions to disseminate accurate information on the legal context are necessary. PMID:27010629

    In the 1970s several states in the Great Lakes region became concerned about mercury contamination in lakes and rivers and were the first to issue local fish consumption advisories. In 2001, the Food and Drug Administration (FDA) advised pregnant women, nursing mothers, young children, and women who may become pregnant not to consume shark, swordfish, king mackerel, and tilefish and recommended that these women not exceed 12 ounces of other fish per week. In 2004, FDA reissued this advice jointly with the U.S. Environmental Protection Agency (EPA) and modified it slightly to provide information about consumption of canned tuna and more details about consumption of recreationally caught fish. Though several studies have examined consumers' awareness of the joint FDA and EPA advisory as well as different state advisories, few used representative data. We examined the changes in awareness and knowledge of mercury as a problem in fish using the pooled nationally representative 2001 and 2006 Food Safety Surveys (FSS) with sample sizes of 4482 in 2001 and 2275 in 2006. Our results indicated an increase in consumers' awareness of mercury as a problem in fish (69% in 2001 to 80% in 2006, p<.001). In our regression models, we found that in both years, parents having children less than 5 years of age were more aware of mercury in fish and knowledgeable about the information contained in the national advisories about mercury in fish (p<.01) than other adults. In both 2001 and 2006, women of childbearing age (aged 18-45) were less aware and knowledgeable about this information than other women. However, women of all age groups had larger gains in awareness and knowledge than their male counterparts during this time. Participants' race, education, income, region, fish preparation experiences, having a foodborne illness in the past year, and risk perceptions about the safety of food were significant predictors of their awareness and knowledge.

  13. The task of the HIV translator: transforming global AIDS knowledge in an awareness workshop.

    2012-01-01

    The globalization of standardized knowledge about HIV and AIDS depends in part on local AIDS awareness educators who receive training from national and international organizations and then, ideally, disseminate what they have learned. In this article I analyze textual and observational data from a five-day introductory AIDS awareness workshop in rural Papua New Guinea. Although the instructor adhered to the handbook provided by the National AIDS Council for much of the information, she departed from it significantly when informing participants about the "root causes" of HIV's spread and in giving them advice about prevention. I explicate where her extratextual knowledge came from as well as its overall message to target audiences. I suggest that textual silences in AIDS awareness handbooks can motivate local HIV translators to embark on a kind of semiosis-the ongoing production of new, hybrid knowledge about HIV.

    Objective To assess correlates of human papillomavirus (HPV) awareness, knowledge, and attitudes among older, church-going African-American women. Methods Participants (N = 759), aged 40-80, answered survey questions about HPV awareness, knowledge, and attitudes toward vaccination of adolescent daughters. Associations between participant characteristics and HPV items were assessed using chi-square tests and logistic regression analyses. Results Younger age, higher education, a family history of cancer, and less spirituality were each associated with HPV awareness individually, and when considered jointly in a single model (p values ≤.038). Higher education was related to HPV knowledge (p = .006). Conclusions African-American women of older age, less education, no family history of cancer, and/or higher spirituality might benefit from targeted church-based HPV educational campaigns.

    Setting: Forty hard-to-reach villages in the East and West Singhbhum Districts of Jharkhand State, India. Objectives: To document knowledge and awareness of tuberculosis (TB) among the general population, understand gender differences and inform intervention activities for the improvement of TB control programmes in tribal-dominant hard-to-reach areas in India. Design: A cross-sectional community-based survey was carried out among 825 respondents using population proportionate sampling. Results: Most of the respondents were in the 18–35 years age group, tribal and married; 44% were illiterate. The study shows poor knowledge about TB symptoms, causes, modes of transmission and moderate awareness about government TB services. Correct knowledge about the cause of TB was negligible: half of the respondents reported local liquor as the cause, 61% considered TB as transmissible and one third considered sharing of food as the mode of transmission. Awareness about the availability of free treatment services at government health facilities was high, but awareness about DOTS was low. Significant gender differences were observed in knowledge and awareness levels. Conclusion: Study findings point to the importance of urgent intensification of culturally congruent and gender-sensitive advocacy, communication and social mobilisation activities. PMID:26400809

    Introduction Various studies have reported poor awareness and knowledge of dentistry in the Nigerian population. There is, however, paucity of information assessing the knowledge and awareness of medical doctors/students and nurses about dentistry. The present study is aimed at determining the knowledge and awareness of medical doctors/students and nurses about dentistry. Methods Self-administered questionnaires were randomly distributed among medical doctors/students, and nurses of Obafemi Awolowo Teaching Hospitals’ Complex, Ile-Ife, Nigeria. Information collected using the questionnaire included participants’ biodata, questions evaluating dental awareness, knowledge of systemic and oral health connections as well as referral practices. The data analysis was done with STATA version 11 software. Results A total of 300 questionnaires were randomly distributed among doctors/students and nurses, 206 were returned (response rate of 69%). Of the returned questionnaires, 129(63%) were males and 77(37%) were females. There were 42 medical doctors, 49 nurses and 115 medical students. The mean age of the participants was 26.7 years (SD 5.2). Majority (99.5%) was aware of dental profession, but 92% had never referred patients for dental consultation. One third (31%) of medical doctors believed that Ludwig angina was a cardiac disease. A large proportion of the respondents (61%) see no need for routine dental visit while 27% would want to visit the dentist only when they had a dental complaint. Conclusion Although a large percentage of the participants claimed to be aware of dentistry, our findings revealed low level of knowledge and attitude to Dentistry. Efforts should be made towards closing this knowledge gap to achieve efficient oral health. PMID:27303588

    2013-09-01

    We describe a foveated compressive sensing approach for image analysis applications that utilizes knowledge of the task to be performed to reduce the number of required measurements compared to conventional Nyquist sampling and compressive sensing based approaches. Our Compressive Optical Foveated Architecture (COFA) adapts the dictionary and compressive measurements to structure and sparsity in the signal, task, and scene by reducing measurement and dictionary mutual coherence and increasing sparsity using principles of actionable information and foveated compressive sensing. Actionable information is used to extract task-relevant regions of interest (ROIs) from a low-resolution scene analysis by eliminating the effects of nuisances for occlusion and anomalous motion detection. From the extracted ROIs, preferential measurements are taken using foveation as part of the compressive sensing adaptation process. The task-specific measurement matrix is optimized by using a novel saliency-weighted coherence minimization with respect to the learned signal dictionary. This incorporates the relative usage of the atoms in the dictionary. Therefore, the measurement matrix is not random, as in conventional compressive sensing, but is based on the dictionary structure and atom distributions. We utilize a patch-based method to learn the signal priors. A treestructured dictionary of image patches using KSVD is learned which can sparsely represent any given image patch with the tree-structure. We have implemented COFA in an end-to-end simulation of a vehicle fingerprinting task for aerial surveillance using foveated compressive measurements adapted to hierarchical ROIs consisting of background, roads, and vehicles. Our results show 113x reduction in measurements over conventional sensing and 28x reduction over compressive sensing using random measurements.

  19. Local newspapers, drinking water pathways, and dimensions of knowledge: Public awareness amid the hydrofracking debate

    NASA Astrophysics Data System (ADS)

    Berg, Weston

    Studies on determinants of pro-environmental behavior have found environmental knowledge to be a prerequisite for public participation. While much has been written on correlations between media coverage and environmental knowledge in general, a gap exists concerning the linkages between media coverage and knowledge of an individual's local environment. This study measures public awareness of local drinking water supplies in urban communities, using a face-to-face survey of 90 respondents in three upstate New York cities. The findings show no significant correlation between newspaper coverage of local water issues and awareness of one's drinking water source; however, the surveys revealed high correlations between such awareness and home ownership (as opposed to renting) and between awareness and receiving a water bill. In addition, there was a positive correlation between reading about a local water-related issue (in this case, hydraulic fracturing for natural gas in the Marcellus Shale) in a local newspaper and possessing basic knowledge of that issue. These findings contribute to previous research on environmental knowledge, and have practical applications in efforts addressing: civic engagement, public understanding of science, citizen participation, and democratic practices.

    Human bocavirus (HBoV) is a parvovirus isolated about a decade ago and found worldwide in both respiratory samples, mainly from early life and children of 6-24 mo of age with acute respiratory infection, and in stool samples, from patients with gastroenteritis. Since then, other viruses related to the first HBoV isolate (HBoV1), namely HBoV2, HBoV3 and HBoV4, have been detected principally in human faeces. HBoVs are small non-enveloped single-stranded DNA viruses of about 5300 nucleotides, consisting of three open reading frames encoding the first two the non-structural protein 1 (NS1) and nuclear phosphoprotein (NP1) and the third the viral capsid proteins 1 and 2 (VP1 and VP2). HBoV pathogenicity remains to be fully clarified mainly due to the lack of animal models for the difficulties in replicating the virus in in vitro cell cultures, and the fact that HBoV infection is frequently accompanied by at least another viral and/or bacterial respiratory and/or gastroenteric pathogen infection. Current diagnostic methods to support HBoV detection include polymerase chain reaction, real-time PCR, enzyme-linked immunosorbent assay and enzyme immunoassay using recombinant VP2 or virus-like particle capsid proteins, although sequence-independent amplification techniques combined with next-generation sequencing platforms promise rapid and simultaneous detection of the pathogens in the future. This review presents the current knowledge on HBoV genotypes with emphasis on taxonomy, phylogenetic relationship and genomic analysis, biology, epidemiology, pathogenesis and diagnostic methods. The emerging discussion on HBoVs as true pathogen or innocent bystander is also emphasized.

    Only some, but not all, individuals who practice tasks with dual structure, overt and covert, are able to comprehend consciously a hidden regularity. The formation of implicit representations of regularity has been proposed to be critical for subsequent awareness. However, explicit knowledge also has been predicted by the activation of executive control systems during task encoding. The present study analyzed performance patterns in participants who could comprehend task regularity and those who could not at delayed recall. Specifically, the role of practice-based knowledge of sequence for individual awareness was focused on. A lateralized variant of the visual serial response time task (SRTT) comprising structured and random blocks was practiced in implicit conditions by 109 participants before and after 10-h retention, with explicit knowledge about covert sequence tested thereafter. Sequence learning was quantified using the normalized difference between response speed in regular and subsequent random blocks. Patterns of performance dynamics were evaluated using response speed, response variability, and error rate. Major results demonstrate that (1) All participants who became aware of the sequence (solvers), gained practice-based sequence knowledge at learning or after retention, (2) Such knowledge also was accumulated during learning by participants who remained fully unaware about covert task structure, (3) Only in explicit solvers, however, was sequence-specific learning accompanied by a prominent increase in performance variability. (4) Specific features and dynamics of performance patterns distinguished different cognitive modes of SRTT processing, each of which supported subsequent knowledge awareness. It is concluded that a behavioral precursor of sequence awareness is the combination of speeded sequence processing and increased performance variability, pointing to an interaction between implicit and explicit processing systems.

    Background: Ergonomics awareness helps in its right application and contributes significantly to general wellbeing and safety of worker at workplace. Aim: This cross-sectional descriptive study aimed at assessing the level of awareness and knowledge of the science of ergonomics among Medical Laboratory Scientists in Benin City, Nigeria. Subjects and Methods: A total of 106 medical laboratory scientists comprising 64 and 42 in public and private laboratories, respectively, were recruited for this study using systematic random sampling technique. Data were obtained from the study participants using a questionnaire and subsequently analyzed with the statistical software INSTAT®. Results: Out of 106 study participants, 27 (25.5%) were reported to have heard of the term ergonomics. Awareness was significantly associated with gender (male vs. female: 38.5% [15/39] vs. 17.9% [12/67]; odds ratio = 2.9; 95% confidence interval = 1.2, 7.1;P = 0.02). Awareness of ergonomics was not significantly affected by affiliation (P = 0.18), area of specialization (P = 0.78), post-qualification experience (P = 0.43), and educational qualification (P = 0.23) of the study participants. Irrespective of the affiliation of the participant, only 6 of 27 (22.2%) participants who were aware of ergonomics knew at least a benefit of right application of ergonomics in the laboratory. Knowledge of risk factors for the development of musculoskeletal disorders was reported by 8 of 27 (29.6%) persons who claimed to be aware of ergonomics. Conclusions: Awareness of ergonomics and knowledge of gains of its right application was poor among the study participants. Regular ergonomic education of medical laboratory scientists in Nigeria is advocated. PMID:27057381

    Lee, Dayong; Huestis, Marilyn A.

    2015-01-01

    Oral fluid (OF) is a new biological matrix for clinical and forensic drug testing, offering non-invasive and directly observable sample collection reducing adulteration potential, ease of multiple sample collections, lower biohazard risk during collection, recent exposure identification, and stronger correlation with blood than urine concentrations. Because cannabinoids are usually the most prevalent analytes in illicit drug testing, application of OF drug testing requires sufficient scientific data to support sensitive and specific OF cannabinoid detection. This review presents current knowledge on OF cannabinoids, evaluating pharmacokinetic properties, detection windows, and correlation with other biological matrices and impairment from field applications and controlled drug administration studies. In addition, on-site screening technologies, confirmatory analytical methods, drug stability, and effects of sample collection procedure, adulterants, and passive environmental exposure are reviewed. Delta-9-tetrahydrocannabinol OF concentrations could be > 1000 μg/L shortly after smoking, whereas minor cannabinoids are detected at 10-fold and metabolites at 1000-fold lower concentrations. OF research over the past decade demonstrated that appropriate interpretation of test results requires a comprehensive understanding of distinct elimination profiles and detection windows for different cannabinoids, which are influenced by administration route, dose, and drug use history. Thus, each drug testing program should establish cutoff criteria, collection/analysis procedures, and storage conditions tailored to its purposes. Building a scientific basis for OF testing is on-going, with continuing OF cannabinoids research on passive environmental exposure, drug use history, donor physiological conditions, and oral cavity metabolism needed to better understand mechanisms of cannabinoid OF disposition and expand OF drug testing applicability.

    2013-05-01

    Being aware of someone else's existing knowledge is a prerequisite to effectively adapting an explanation to that person's learning needs. However, such knowledge awareness introduces the potential for motivated self-evaluation based on relative knowledge, that is, for social comparison. Because favorable social comparisons are actively defended, we propose that knowledge awareness might undermine information sharing in explanation when social comparison motives are active. We tested this hypothesis in a series of experiments in which participants provided explanations to an ostensible learning partner with or without knowledge awareness. Both dispositionally and situationally motivated social comparison interacted with knowledge awareness to reduce information sharing in explanation. Intriguingly, knowledge awareness uniformly facilitated adaptation of the information that was shared to address partner knowledge deficit. These results illustrate a tension in the components of effective explanation. At the same time that knowledge awareness effectively coordinates explanation content, it can lead to knowledge hoarding by knowledgeable explainers who are motivated to rely on knowledge differences between the self and the explanation recipient for self-evaluation.

    2016-08-01

    Individuals overdue for recommended cancer screenings may not be receiving adequate cancer prevention education. Since Latinas have the highest incidence of cervical cancer among all racial/ethnic groups, human papillomavirus (HPV) vaccination education is especially important for this population. The correlates of HPV vaccine-related awareness and knowledge were assessed among Latinas who were overdue for recommended cancer screenings. N = 206 Latinas who were overdue for recommended cancer screenings were recruited by health educators from local community groups. Bivariate analyses and multivariable regression models were used to investigate factors associated with HPV vaccine-related awareness and knowledge among participants as well as to assess correlates of HPV vaccine receipt for eligible children of participants. In multivariable regression analyses, years living in the U.S. (p = 0.05) and health insurance status (p = 0.03) were significantly related to HPV vaccine-related knowledge measures. Age (p < 0.01), birthplace (p = 0.02), years living in the U.S. (p = 0.05), annual household income (p = 0.05), cervical cancer screening status (p = 0.03), and HPV vaccine-related knowledge measures (p < 0.01) were significantly associated with HPV vaccination outcomes for eligible daughters of participants. Cervical cancer screening status (p = 0.02) and HPV vaccine-related knowledge measures (p = 0.01) were significantly associated with HPV vaccination outcomes for eligible sons of participants. Results indicate poor HPV vaccine-related awareness and knowledge among Latinas. Interventions to improve HPV vaccine-related awareness and knowledge in Utah's growing Latino population should target vulnerable individuals (e.g., not employed outside the home, less educated, less acculturated, poor, uninsured, overdue for cervical cancer screening) by using materials that are culturally sensitive, linguistically appropriate, and easily accessible.

    Background. Our study examined hepatitis B virus (HBV) awareness and knowledge in Asian communities in British Columbia (BC). Methods. A statistical random sample representation of Chinese, Korean, Filipino, South Asian, and Southeast Asian populations in Greater Vancouver was surveyed by telephone. Multiple logistic regression analysis was performed to identify predictors of HBV knowledge. Results. General awareness of HBV was reported in 78.8% (798/1013). HBV awareness was the highest in Chinese (89%) and Filipino (88%) populations and the lowest in the South Asian (56%) population. "Reasonable" knowledge of HBV was elicited in 76.8% (778/1013). Higher HBV knowledge was associated with younger age (p = 0.014), higher education (p < 0.0001), Chinese ethnicity (p < 0.0001), and use of media (p = 0.01) and Internet (p = 0.024) for health information. Compared to the Chinese (OR = 1.0) population, "reasonable" knowledge of HBV was lower in Korean (OR = 0.3, 95% CI: 0.1-0.5), Filipino (OR = 0.3, 95% CI: 0.2-0.6), South Asian (OR = 0.3, 95% CI: 0.2-0.4), and Southeast Asian (OR = 0.3, 95% CI: 0.1-0.6) populations. 54.8% (555/1013) felt that HBV education was inadequate and 80.1% (811/1013) preferred HBV education in their native languages. Conclusion. Compared to the Chinese population, other Asian communities in BC have lower HBV awareness and knowledge. Public education should target older and less educated and Korean, Filipino, South Asian, and Southeast Asian populations in their native languages via media and Internet. PMID:27446839

    2014-01-01

    Objective Listeners use their knowledge of how language is structured to aid speech recognition in everyday communication. When it comes to children with congenital hearing loss severe enough to warrant cochlear implants (CIs), the question arises of whether these children can acquire the language knowledge needed to aid speech recognition, in spite of only having spectrally degraded signals available to them. That question was addressed in the current study. Specifically there were three goals: (1) to compare the language structures used by children with CIs to those of children with normal hearing (NH); (2) to assess the amount of variance in the language measures explained by phonological awareness and lexical knowledge; and (3) to assess the amount of variance in the language measures explained by factors related to the hearing loss itself and subsequent treatment. Design Language samples were obtained and transcribed for 40 children who had just completed kindergarten: 19 with NH and 21 with CIs. Five measures were derived from Systematic Analysis of Language Transcripts (SALT): (1) mean length of utterance in morphemes, (2) number of conjunctions, excluding and, (3) number of personal pronouns, (4) number of bound morphemes, and (5) number of different words. Measures were also collected on phonological awareness and lexical knowledge. Statistics examined group differences, as well as the amount of variance in the language measures explained by phonological awareness, lexical knowledge, and factors related to hearing loss and its treatment for children with CIs. Results Mean scores of children with CIs were roughly one standard deviation below those of children with NH on all language measures, including lexical knowledge, matching outcomes of other studies. Mean scores of children with CIs were closer to two standard deviations below those of children with NH on two out of three measures of phonological awareness (specifically those related to phonemic

    ABSTRACT Introduction: Often people responsible for the oral care of children feel or believe that since primary teeth will eventually shed, it is not worthwhile to spend time/money on providing good oral health to children. Parents are the ones who take care of their children and make decisions for them. Hence, they should have knowledge about primary teeth, their health and caring in order to build confidence in their children through tiny teeth. Aim: To assess the knowledge of primary teeth and their importance among parents with children below 12 years. Materials and methods: A total of 1,000 questionnaires containing questions written both in English and in the local language (Kannada) were prepared for data collection and were personally distributed to parents visiting dental clinics for their children’s dental treatment. Statistical analysis: Both descriptive statistics and Chi-square test were used. Results: Complaints related to dental caries constituted 82% of children visiting dental clinics among children in Bengaluru city. Only 39% of respondents were aware of all functions of primary teeth. Conclusion: The present study revealed that the parents of Bengaluru city had superficial or partial knowledge of primary teeth and that there is a need to improve this awareness.

    Objective: This study aimed to assess the knowledge, awareness, and perception of contraception among senior pharmacy students of a public sector university in Malaysia. Methods: A cross-sectional, questionnaire-based study was conducted among senior pharmacy students. The pretested questionnaire was used to collect data from the participants over the period of 1-month. The questionnaire was divided into four sections, for gathering the information about students’ demographic data, and their knowledge, attitudes, and perception toward contraception. Data were statistically analyzed using SPSS version 20. Findings: The response rate was 68.6%. The results showed that the contraceptive knowledge was comparatively higher in year four students (P < 0.001), married respondents (P < 0.001) and those taking elective courses (P = 0.022) as compared to their respective counterparts. Majority of the students were well aware and had a positive perception about contraception. Conclusion: Overall findings reflect that the majority of the students had good knowledge, perception, and awareness about contraception. The study recommends future studies to be conducted covering different pharmacy schools across the country to further establish the results. PMID:25984548

    Sleep has been identified as a critical brain state enhancing the probability of gaining insight into covert task regularities. Both non-rapid eye movement (NREM) and rapid eye movement (REM) sleep have been implicated with offline re-activation and reorganization of memories supporting explicit knowledge generation. According to two-stage models of sleep function, offline processing of information during sleep is sequential requiring multiple cycles of NREM and REM sleep stages. However, the role of overnight dynamic sleep macrostructure for insightfulness has not been studied so far. In the present study, we test the hypothesis that the frequency of interactions between NREM and REM sleep stages might be critical for awareness after sleep. For that aim, the rate of sleep stage transitions was evaluated in 53 participants who learned implicitly a serial reaction time task (SRTT) in which a determined sequence was inserted. The amount of explicit knowledge about the sequence was established by verbal recall after a night of sleep following SRTT learning. Polysomnography was recorded in this night and in a control night before and was analyzed to compare the rate of sleep-stage transitions between participants who did or did not gain awareness of task regularity after sleep. Indeed, individual ability of explicit knowledge generation was strongly associated with increased rate of transitions between NREM and REM sleep stages and between light sleep stages and slow wave sleep. However, the rate of NREM–REM transitions specifically predicted the amount of explicit knowledge after sleep in a trait-dependent way. These results demonstrate that enhanced lability of sleep goes along with individual ability of knowledge awareness. Observations suggest that facilitated dynamic interactions between sleep stages, particularly between NREM and REM sleep stages play a role for offline processing which promotes rule extraction and awareness.

    Introduction Individuals residing in Limpopo, KwaZulu-Natal and the Eastern Cape provinces who had access to public health services were surveyed to determine public knowledge and awareness of the new National Health Insurance (NHI). Methods A descriptive cross-sectional study was conducted and a total of 748 adult respondents were sampled using a two-stage systematic sampling design. Data were collected using mobile phone assisted personal interviews. Results The study found that 80.3% of the respondents were aware of the NHI and slightly less than half (49.8%) of the respondents did not have knowledge of how the NHI works and 71.8% lacked awareness about the origin of the development of the NHI concept in South Africa. The knowledge of what the NHI would pay for was poor and 48.1% knew that the NHI Fund would pay for medical expenses if a person got sick and 45.7% knew that with health insurance, basic health requirement is ensured and that if one becomes ill, medical treatment would be paid for by the NHI Fund, 50.9% of respondents did not understand how the NHI Fund will pay for health care received, only 44.8% understood how the NHI will pay for health care services received. Conclusion The public education campaigns to increase knowledge and understanding of the NHI scheme might have been inadequate hence might not have penetrated many communities. It is recommended that a comprehensive community consultation plan be established to increase awareness and knowledge of the NHI among community members targeting clinics, schools, pension pay points and other community sites.

    Aim: The present study was conducted to assess the awareness, knowledge, and risks of zoonotic diseases among livestock farmers in Punjab. Materials and Methods: 250 livestock farmers were selected randomly and interviewed with a pretested questionnaire, which contained both open and close ended questions on different aspects of zoonotic diseases, i.e., awareness, knowledge, risks, etc. Knowledge scorecard was developed, and each correct answer was awarded one mark, and each incorrect answer was given zero mark. Respondents were categorized into low (mean − ½ standard deviation [SD]), moderate (mean ± ½ SD), and high knowledge (Mean + ½ SD) category based on the mean and SD. The information about independent variables viz., age, education, and herd size were collected with the help of structured schedule and scales. The data were analyzed by ANOVA, and results were prepared to assess awareness, knowledge, and risks of zoonotic diseases and its relation with independent variables. Results: Majority of the respondents had age up to 40 years (70%), had their qualification from primary to higher secondary level (77.6%), and had their herd size up to 10 animals (79.6%). About 51.2% and 54.0% respondents had the history of abortion and retained placenta, respectively, at their farms. The respondents not only disposed off the infected placenta (35.6%), aborted fetus (39.6%), or feces (56.4%) from a diarrheic animal but also gave intrauterine medication (23.2%) bare-handedly. About 3.6-69.6% respondents consumed uncooked or unpasteurized animal products. About 84.8%, 46.0%, 32.8%, 4.61%, and 92.4% of livestock farmers were aware of zoonotic nature of rabies, brucellosis, tuberculosis, anthrax, and bird flu, respectively. The 55.6%, 67.2%, 52.0%, 64.0%, and 51.2% respondents were aware of the transmission of zoonotic diseases to human being through contaminated milk, meat, air, feed, or through contact with infected animals, respectively.

    Background. Sickle cell anaemia (SCA) is an inherited condition whose clinical manifestations arise from the tendency of haemoglobin to polymerize and deform red blood cells into characteristic sickle shape. Allogeneic bone marrow transplantation offers a cure. The aim of this study was to determine the level of awareness, knowledge, and acceptance of this beneficial procedure in Nigeria. Materials and Methods. This multicentre cross-sectional study was conducted in 7 tertiary hospitals in Nigeria in 2015. Approval was obtained from each institution's research and ethics committee. A pretested structured questionnaire was administered to respondents aged 18 years and above and to the parents or guardians of those below 18 years of age. Results. There were 265 respondents comprising 120 males and 145 females. One hundred and seventy-one (64.5%) respondents were aware of BMT for the treatment of SCA. About 67.8% (116 of 171) of those who were aware believed SCA can be cured with BMT (p = 0.001) and 49.7% (85 of 171) of the respondents accepted BMT (p = 0.001). Conclusion. Awareness of BMT in Nigeria is low when compared with reports from developed countries. The knowledge is poor and acceptance is low. With adequate information, improved education, and psychological support, more Nigerians will embrace BMT. PMID:27774320

    Aim: Despite fixed professional opinion of what might constitute optimal treatment, patients must be informed of the various treatment options available in orthodontics to manage their clinical problem. The purpose of this study was to compare and evaluate the knowledge and awareness among practicing orthodontists and patients with regard to informed consent in clinical practice and research. Materials and Methods: Twenty-five orthodontists and 25 patients were enrolled in a questionnaire study which was descriptive and cross-sectional in the nature. The questionnaire focused on the following aspects; contents of informed consent, at what age and who can give consent. Results: The study showed a majority of orthodontists (79.14%) were aware of knowledge regarding informed consent when compared to patients(35.14%). Conclusion: The overall result showed the huge gap that exists between orthodontists and patients and thus making it categorical for patients to be more involved in the decision-making process.

    Forensic dentistry involves the processing, review, evaluation, and presentation of dental evidence with the purpose of contributing scientific and objective data to legal processes. The present, systematic review was conducted to assess knowledge and awareness of forensic odontology among dentists in India. A systematic review of relevant cross-sectional studies was conducted regarding the level of knowledge, awareness, and practical application of forensic odontology among dentists in India. Four out of 129 studies were finally included in the present review after conducting a search of both electronic and manual scientific databases. Potential biases were addressed and the relevant data were extracted by the concerned investigators. Almost all the subjects were familiar with the subject of forensic odontology in one of the study reports. Only 12% of dentists were maintaining complete dental records in the findings of another study. Only 4% of dentists reported to have contributed to the identification of victims in a mass disaster in yet another study. The findings of another study revealed that 40% of dental practitioners did not have the expertise to identify child abuse. The results of the present review showed that the knowledge and awareness level of subjects was inadequate and that there is considerable variation in the practice of forensic odontology among dentists. It is necessary to expose dentists to the basic principles and techniques of the subject. PMID:27051215

    After further controversies, the definition of hypnosis is to be at the same time a modified state of consciousness and a particular intersubjective relation between a practitioner and his patient. In a synthetic way, we can say that mechanisms of hypnosis on acute pain are now well known, and its efficiency is particularly proved in the pain provoked by the care. On the other hand, the knowledge concerning the action of the hypnosis on chronic pain is much more complex to understand. If the hypnosis allows connoting differently pain and to decrease its implication in patient's life, otherWise the long-term reorganizations of hypnosis on chronic pain are still for the study. In practice, the field which his particularly in development is the analogical processes of the speech, because they are particularly present in pain medicine, and easy to use in hypnotic method.

    Individuals overdue for recommended cancer screenings may not be receiving adequate cancer prevention education. Since Latinas have the highest incidence of cervical cancer among all racial/ethnic groups, human papillomavirus (HPV) vaccination education is especially important for this population. The correlates of HPV vaccine-related awareness and knowledge were assessed among Latinas who were overdue for recommended cancer screenings. N = 206 Latinas who were overdue for recommended cancer screenings were recruited by health educators from local community groups. Bivariate analyses and multivariable regression models were used to investigate factors associated with HPV vaccine-related awareness and knowledge among participants as well as to assess correlates of HPV vaccine receipt for eligible children of participants. In multivariable regression analyses, years living in the U.S. (p = 0.05) and health insurance status (p = 0.03) were significantly related to HPV vaccine-related knowledge measures. Age (p < 0.01), birthplace (p = 0.02), years living in the U.S. (p = 0.05), annual household income (p = 0.05), cervical cancer screening status (p = 0.03), and HPV vaccine-related knowledge measures (p < 0.01) were significantly associated with HPV vaccination outcomes for eligible daughters of participants. Cervical cancer screening status (p = 0.02) and HPV vaccine-related knowledge measures (p = 0.01) were significantly associated with HPV vaccination outcomes for eligible sons of participants. Results indicate poor HPV vaccine-related awareness and knowledge among Latinas. Interventions to improve HPV vaccine-related awareness and knowledge in Utah's growing Latino population should target vulnerable individuals (e.g., not employed outside the home, less educated, less acculturated, poor, uninsured, overdue for cervical cancer screening) by using materials that are culturally sensitive, linguistically appropriate, and easily accessible.

    Experimental animal models are crucial in the study of biological behavior and pathological development of cancer, and evaluation of the efficacy of novel therapeutic or preventive agents. A variety of animal models that recapitulate human urothelial cell carcinoma have thus far been established and described, while models generated by novel techniques are emerging. At present a number of reviews on animal models of bladder cancer comprise the introduction of one type of method, as opposed to commenting on and comparing all classifications, with the merits of a certain method being explicit but the shortcomings not fully clarified. Thus the aim of the present study was to provide a summary of the currently available animal models of bladder cancer including transplantable (which could be divided into xenogeneic or syngeneic, heterotopic or orthotopic), carcinogen-induced and genetically engineered models in order to introduce their materials and methods and compare their merits as well as focus on the weaknesses, difficulties in operation, associated problems and translational potential of the respective models. Findings of these models would provide information for authors and clinicians to select an appropriate model or to judge relevant preclinical study findings. Pertinent detection methods are therefore briefly introduced and compared. PMID:25120584

    Francisella tularensis belongs to the family Francisellaceae. It is the aetiological agent of a zoonosis called tularaemia, spread throughout the northern hemisphere. Currently, several subspecies of F. tularensis may be distinguished with various pathogenicity and geographical distribution. In human medicine, only sporadic infections or local epidemics are reported. Given the fact that F. tularensis is highly pathogenic for humans and is easily spread by aerosol, water or food, it may be exploited as a biological weapon. It belongs to fastidious strains requiring specially prepared culture media.

    Faecal incontinence (FI) is a disabling and frequent symptom since its prevalence can vary between 5% and 15% of the general population. It has a particular negative impact on quality of life. Many tools are currently available for the treatment of FI, from conservative measures to invasive surgical treatments. The conservative treatment may be dietetic measures, various pharmacological agents, anorectal rehabilitation, posterior tibial nerve stimulation, and transanal irrigation. If needed, patients may have miniinvasive approaches such as sacral nerve modulation or antegrade irrigation. In some cases, a surgical treatment is proposed, mainly external anal sphincter repair. Although these different therapeutic options are available, new techniques are arriving allowing new hopes for the patients. Moreover, most of them are non-invasive such as local application of an α1-adrenoceptor agonist, stem cell injections, rectal injection of botulinum toxin, acupuncture. New more invasive techniques with promising results are also coming such as anal magnetic sphincter and antropylorus transposition. This review reports the main current available treatments of FI and the developing therapeutics tools. PMID:26909229

    Recent findings link fronto-temporal gamma electroencephalographic (EEG) activity to conscious awareness in dreams, but a causal relationship has not yet been established. We found that current stimulation in the lower gamma band during REM sleep influences ongoing brain activity and induces self-reflective awareness in dreams. Other stimulation frequencies were not effective, suggesting that higher order consciousness is indeed related to synchronous oscillations around 25 and 40 Hz.

    Bruxism is defined as the repetitive jaw muscle activity characterized by the clenching or grinding of teeth. It can be categorized into awake and sleep bruxism (SB). Frequent SB occurs in about 13% of adults. The exact etiology of SB is still unknown and probably multifactorial in nature. Current literature suggests that SB is regulated centrally (pathophysiological and psychosocial factors) and not peripherally (morphological factors). Cited consequences of SB include temporomandibular disorders, headaches, tooth wear/fracture, implant, and other restoration failure. Chairside recognition of SB involves the use of subjective reports, clinical examinations, and trial oral splints. Definitive diagnosis of SB can only be achieved using electrophysiological tools. Pharmacological, psychological, and dental strategies had been employed to manage SB. There is at present, no effective treatment that “cures” or “stops” SB permanently. Management is usually directed toward tooth/restoration protection, reduction of bruxism activity, and pain relief.

    Micronutrient deficiency in the human body, popularly known as "hidden hunger", causes many health problems. It presently affects >2 billion people worldwide, especially in South Asia and sub-Saharan Africa. Biofortification of food crop varieties is one way to combat the problem of hidden hunger using conventional plant breeding and transgenic methods. Lentils are rich sources of protein, micronutrients, and vitamins including iron, zinc, selenium, folates, and carotenoids. Lentil genetic resources including germplasm and wild species showed genetic variability for these traits. Studies revealed that a single serving of lentils could provide a significant amount of the recommended daily allowance of micronutrients and vitamins for adults. Therefore, lentils have been identified as a food legume for biofortification, which could provide a whole food solution to the global micronutrient malnutrition. The present review discusses the current ongoing efforts toward genetic biofortification in lentils using classical breeding and molecular marker-assisted approaches.

    2016-01-01

    Background: Eyesight plays an important role in our day today life. When the vision gets hampered, daily activities of an individual will be affected. The prevalence of visual impairment is increasing across the globe, with more burdens on the developing world. The uptake of low vision services remains to be low in developing countries like India. Methods: A newly constructed questionnaire using information from previously conducted telephonic interviews and article search was administered among 50 eye care practitioners from Kerala, India for the pilot study. Modifications were made in the questionnaire, based on the responses obtained from the pilot study. From their responses, awareness, knowledge, and barriers for the low vision services among eye care practitioners were assessed. Results: (1) Pilot study - the Cronbach's alpha values obtained for knowledge, awareness and barrier questions were 0.814, 0.297, and 0.810, respectively, and content validity index was found to be 0.64. (2) Main study - 211 eye care practitioners from 12 states of India took part in the study that accounted for a response rate of 16.7%. The participants included were 95 (45%) men and 116 (55%) women with a mean age of 28.18 ± 7.04 years. The lack of awareness was found to be the major barrier in the provision and uptake of low vision services from the practitioner's perspective. Conclusion: The study results showed that there is a lack of awareness among eye care practitioners about low vision services, which acts as a major barrier in the effective delivery of these services.

    2013-01-01

    Point-of-care information needs are common and frequently unmet. One solution to this problem is the use of Infobuttons, which are context-sensitive links from electronic health records (EHR) to knowledge resources, sometimes involving an intermediate broker known as an Infobutton Manager. Health Level Seven (HL7) has developed the Context-Aware Knowledge Retrieval (Infobutton) standard to standardize the integration between EHR systems and knowledge resources. While the standard specifies a set of context attributes and standard terminologies, it leaves to knowledge resources the flexibility to decide how to use these attributes and terminologies to retrieve the most relevant content. This paper describes some of the challenges faced by knowledge resources in trying to locate the most relevant content based on the attribute values for a given Infobutton request. Various approaches to content retrieval are discussed, including the role of indexing with standardized codes, the role of text-based search engines together with their ranking algorithms, and the role of hybrid approaches. Knowledge resource developers must carefully consider business rules, heuristics, and precision/recall tradeoffs when implementing the HL7 Infobutton standard. PMID:23077131

    2016-01-01

    It is a controversially debated topic whether stimuli can be analyzed up to the semantic level when they are suppressed from visual awareness during continuous flash suppression (CFS). Here, we investigated whether affective knowledge, i.e., affective biographical information about faces, influences the time it takes for initially invisible faces with neutral expressions to overcome suppression and break into consciousness. To test this, we used negative, positive, and neutral famous faces as well as initially unfamiliar faces, which were associated with negative, positive or neutral biographical information. Affective knowledge influenced ratings of facial expressions, corroborating recent evidence and indicating the success of our affective learning paradigm. Furthermore, we replicated shorter suppression durations for upright than for inverted faces, demonstrating the suitability of our CFS paradigm. However, affective biographical information did not modulate suppression durations for newly learned faces, and even though suppression durations for famous faces were influenced by affective knowledge, these effects did not differ between upright and inverted faces, indicating that they might have been due to low-level visual differences. Thus, we did not obtain unequivocal evidence for genuine influences of affective biographical information on access to visual awareness for faces during CFS. PMID:27119743

    Colorectal cancer ranks as one of the most incidental and death malignancies worldwide. Colorectal cancer screening has proven its benefit in terms of incidence and mortality reduction in randomized controlled trials. In fact, it has been recommended by medical organizations either in average-risk or family-risk populations. Success of a screening campaign highly depends on how compliant the target population is. Several factors influence colorectal cancer screening uptake including sociodemographics, provider and healthcare system factors, and psychosocial factors. Awareness of the target population of colorectal cancer and screening is crucial in order to increase screening participation rates. Knowledge about this disease and its prevention has been used across studies as a measurement of public awareness. Some studies found a positive relationship between knowledge about colorectal cancer, risk perception, and attitudes (perceived benefits and barriers against screening) and willingness to participate in a colorectal cancer screening campaign. The mentioned factors are modifiable and therefore susceptible of intervention. In fact, interventional studies focused on average-risk population have tried to increase colorectal cancer screening uptake by improving public knowledge and modifying attitudes. In the present paper, we reviewed the factors impacting adherence to colorectal cancer screening and interventions targeting participants for increasing screening uptake. PMID:24729896

    Objectives: Proper handling, treatment and disposal of biomedical wastes are important elements in any health care setting. Not much attention has been paid to the management of Biomedical Waste (BMW) in recent years, in dental colleges and hospitals in India. The present systematic review was conducted to assess knowledge and awareness regarding BMW management among staff and students of dental teaching institutions in India. Material and Methods: A systematic review of relevant cross-sectional studies was conducted regarding BMW management in India in dental teaching institutions in India. Six studies were finally included in the present review after conducting both electronic and manual search like Pubmed, EMBASE etc. and after making necessary exclusions. Potential biases were addressed and relevant data was extracted by the concerned investigators. Results: Six studies were finally included in the review. Colour coding of wastes was not done by 67% of the subjects in one of the studies conducted in Haryana. Almost all the subjects agreed to the fact that exposure to hazardous health care waste can result in disease or infection in another study. According to another study reports, none of the respondents was able to list the legislative act regarding BMW when asked. Conclusions: The results of the present review showed that knowledge and awareness level of subjects was inadequate and there is considerable variation in practice and management regarding BMW. There is a great need for continuing education and training programmes to be conducted in dental teaching institutions in India. Key words:Biomedical waste, knowledge, awareness, dentists, institution. PMID:25593667

    The purpose of this review was to collect and interpret the findings of all published qualitative or quantitative research that assessed African Americans' 1) general awareness and/or specific knowledge of the U.S. Public Health Service (USPHS) Syphilis Study at Tuskegee, and 2) attitudes towards and/or willingness to participate in biomedical research. An exhaustive review of the literature produced eight articles that fit the aforementioned selection criteria. All articles that assessed both awareness and knowledge found that familiarity with the USPHS Syphilis Study at Tuskegee did not necessarily ensure accurate knowledge of it. Four studies also found that awareness of the USPHS Syphilis Study at Tuskegee did not relate to willingness to participate in biomedical research. In addition to awareness and knowledge of the USPHS Syphilis Study at Tuskegee, published studies suggest that a broad array of structural and sociocultural factors influence minorities' willingness to participate in biomedical studies.

    College students enrolled in university dining plans are exposed daily to a food environment characterized by foods high in energy, fats, and added sugars, and low in nutrient density. Their decisions about what to eat are currently made in an environment where no nutrition labeling is required. To fill the gap in current literature regarding whether or not increased nutrition knowledge of dietary guidance actually translates into positive behavior, this cross-sectional study investigated self-reported eating patterns of 200 college students. An Internet-based survey was used to identify how closely respondents followed the Dietary Guidelines for Americans 2005, and whether their eating patterns were related to their knowledge of dietary guidance. It was observed that, for fruit, dairy, protein, and whole grains, increased knowledge is related to increased likelihood of meeting dietary guidelines. Moreover, when asked about individual food choices, nutrition knowledge was related to making more healthful choices in every case. Ultimately, increased knowledge of dietary guidance appears to be positively related to more healthful eating patterns. This suggests that guidelines such as the Dietary Guidelines for Americans 2005, in conjunction with effective public-awareness campaigns, may be a useful mechanism for promoting change in what foods consumers choose to eat.

    Introduction: The most prevalent form of hypertension is systolic blood pressure (SBP) and it is considered to be predisposing risk factor for cardiovascular disease. The objective of the study was to assess self-care practices, knowledge and awareness of hypertension, especially related to SBP among cardiac hypertensive patients. Methodology: A Cross sectional study was conducted on 664 cardiac hypertensive patients, which were selected by non-probability convenience sampling from cardiology outpatient department of three tertiary care hospitals. Face to face interviews were conducted using a pre designed questionnaire. Data was entered and analyzed by SPSS (V17). Results: 81.8%, did not know that hypertension is defined as high blood pressure. 97.1% of the sample population did not know that top measurement of blood pressure was referred to as systolic and only 25.0% correctly recognized normal systolic blood pressure to be less than 140mmHg. 7.4% of the patients consulted their doctor for hypertension once or twice in a month. Risk factor for high blood pressure most commonly identified by the participants was too much salt intake Conclusions: The results state that there is an inadequate general knowledge of hypertension among cardiac patients and they do not recognise the significance of elevated SBP levels. There is a need to initiate programs that create community awareness regarding long term complications of uncontrolled hypertension, particularly elevated SBP levels so that there is an improvement in self-care practices of the cardiacpatients.

    Hispanic women have more than a 1.5-fold increased cervical cancer incidence and mortality compared to non-Hispanic white women in the United States. The Centers for Disease Control recommends the HPV vaccine for females at ages 11 and 12 years, though it is approved for females aged 9–26 to protect against the primary types of high-risk HPV (HPV-16 and HPV-18) that cause approximately 70% of cervical cancer cases. Few culturally-tailored Spanish HPV vaccine awareness programs have been developed. This study evaluates the efficacy of a Spanish radionovela as an educational tool. Rural Hispanic parents of daughters aged 9–17 (n = 88; 78 mothers and 10 fathers) were randomized to listen to the HPV vaccine radionovela or to another public service announcement. Participants completed a 30 min pretest posttest questionnaire. Parents who listened to the HPV radionovela (intervention group) scored higher on six knowledge and belief items. They were more likely to confirm that HPV is a common infection (70% vs. 48%, P = .002), to deny that women are able to detect HPV (53% vs. 31%, P = .003), to know vaccine age recommendations (87% vs. 68%, P = .003), and to confirm multiple doses (48% vs. 26%, P = .03) than control group parents. The HPV vaccine radionovela improved HPV and HPV vaccine knowledge and attitudes. Radionovela health education may be an efficacious strategy to increase HPV vaccine awareness among Hispanic parents.

    The purpose of this study was to assess the effects of a cultural competence training (CCT) program on pediatric health care providers' self-reported ability to provide culturally competent care to a diverse pediatric patient population. This quantitative, nested ecologic level study design used a repeated measure in the form of pre-test and post-test data to assess percent change in providers' cultural awareness, experience working or learning about different cultures, and preparedness and skills in working with different cultures before and after CCT. The study was conducted between 2011 and 2012 in a pediatric hospital and associated outpatient offices. The sample consisted of pediatric health care providers from various departments, mainly physicians and nurses (n = 69). Participants completed a pre-intervention cultural competence assessment and then were subjected to a cultural competence-training program, after which they completed the assessment a second time. The baseline and post-intervention data were collected in the form of Likert scales and transformed into a quintile or quartile scale as appropriate. Data were assessed using paired t-tests or Wilcoxon's signed-rank tests. Providers indicated a 13% increase in knowledge (53.9% vs. 66.7%, t = 3.4, p = 0.001), 8.7% increase in awareness (46.7% vs. 55.4%, t = 3.0, p = 0.002), and 8% statistically marginal increase in skills (66.4% vs. 74.5%, z = 1.8, p = 0.06). Culturally competent training in a pediatric environment significantly enhances knowledge, awareness and to some extent skills in providing care to culturally diverse patient population.

    Background Medical students can be exposed to serious health care-associated infections, if they are not following infection prevention and control (IPC) measures. There is limited information regarding the knowledge, awareness, and practices of medical students regarding IPC and the educational approaches used to teach them these practices. Aim To evaluate the knowledge, awareness, and attitude of medical students toward IPC guidelines, and the learning approaches to help improve their knowledge. Methods A cross-sectional, interview-based survey included 73 medical students from Weill Cornell Medical College, Qatar. Students completed a questionnaire concerning awareness, knowledge, and attitude regarding IPC practices. Students’ knowledge was assessed by their correct answers to the survey questions. Findings A total of 48.44% of the respondents were aware of standard isolation precautions, 61.90% were satisfied with their training in IPC, 66.13% were exposed to hand hygiene training, while 85.48% had sufficient knowledge about hand hygiene and practiced it on a routine basis, but only 33.87% knew the duration of the hand hygiene procedure. Conclusion Knowledge, attitude, and awareness of IPC measures among Weill Cornell Medical Students in Qatar were found to be inadequate. Multifaceted training programs may have to target newly graduated medical practitioners or the training has to be included in the graduate medical curriculum to enable them to adopt and adhere to IPC guidelines.

    Background: The awareness, knowledge, and involvement of teachers in the implementation of School Health Programme (SHP) in secondary schools are essential in ensuring the effectiveness and overall success of the School Health Policy. This study assessed the awareness and knowledge of teachers on SHP in Ibadan metropolis. Methods: A descriptive cross-sectional study was carried out using a two-stage sampling technique to select 426 secondary school teachers across all the five Urban Local Government Areas (LGAs) in Ibadan metropolis by balloting. Pretested semi-structured questionnaires were used to collect data from 426 teachers. Quantitative data were analyzed using descriptive statistics, Chi-square, and logistics regression tests at 5% level of significance. Results: About one-third of the respondents had heard of National School Health Policy (NSHP); however, few had seen the document. About half of the respondents were aware of the SHP in their schools. Many of the respondents had a good knowledge of SHP. Age and level of education of participants significantly influenced the knowledge of SHP. Above 50 years of age and postgraduate qualification were the significant predictors for the good knowledge of SHP. Conclusions: Awareness of the NSHP was low despite the good knowledge of SHP. This could be due to the tertiary education that most of the respondents had. Concerted efforts of stakeholders are required to intensify the health education awareness campaign to improve teachers’ knowledge based on NSHP.

    This study extended the findings of Tighe and Schatschneider (2015) by investigating the predictive utility of separate dimensions of morphological awareness as well as vocabulary knowledge to reading comprehension in adult basic education (ABE) students. We competed two- and three-factor structural equation models of reading comprehension. A three-factor model of real word morphological awareness, pseudoword morphological awareness, and vocabulary knowledge emerged as the best fit and accounted for 79% of the reading comprehension variance. The results indicated that the constructs contributed jointly to reading comprehension; however, vocabulary knowledge was the only potentially unique predictor (p = 0.052), accounting for an additional 5.6% of the variance. This study demonstrates the feasibility of applying a latent variable modeling approach to examine individual differences in the reading comprehension skills of ABE students. Further, this study replicates the findings of Tighe and Schatschneider (2015) on the importance of differentiating among dimensions of morphological awareness in this population.

    Our study investigated if phonological awareness and letter-sound knowledge were predictors of reading progress in children with intellectual disabilities (ID) with unspecified etiology. An academic achievement test was administered to 129 children with mild or moderate ID when they were 6-8 years old, as well as one and two school years later. Findings indicated that phonological awareness and letter-sound knowledge at 6-8 years of age predicted progress in word and non-word reading after one school year and two school years after controlling for IQ, age, expressive vocabulary, spoken language, and type of placement. Phonological awareness and letter-sound knowledge at 6-8 years of age also predicted progress in reading comprehension after one school year and two school years. These findings suggest that training phonological awareness skills combined with explicit phonics instruction is important to foster reading progress in children with mild and moderate ID with unspecified etiology.

    A cross-sectional study was carried out among HCPs in Northwest General Hospital & Research Centre, Hayatabad Peshawar, Pakistan. The purpose of this study was to investigate knowledge, awareness and attitude of HCPs towards influenza vaccination. A total of N=170 questionnaires were distributed among the staff. There was a 97% response rate to this survey (n=165). The median age of the respondents was 30 years and most of them, 98 (59.0%), were from age group of 24-30 years. The majority of the HCPs that participated in this study were male 106 (64.2%), and by profession, the majority were physicians 77 (46.7%), followed by pharmacists and nurses. A majority 114 (69.1%) believed that it was not compulsory for HCPs to get vaccinated for influenza. Top three identified barriers to vaccination were: not everyone is familiar with the availability of the influenza vaccination at their institution (Relative importance weight factors (RIWF)=0.71), due to needle fear I do not like to get vaccinated (RIWF=0.70) and it is not compulsory for healthcare professionals to get vaccinated for influenza (RIWF=0.64). The logistic regression analysis has revealed association for job experience and profession with the most of the eleven knowledge item. However, when overall sum of eleven items were tested to identify the factors affecting the knowledge score, along with profession (-0.215 [-0.389 to 0.040]; p=0.016) and job experience (0.823 [0.521-1.125]; p<0.001) HCPs age (-0.409 [-0.755 to -0.064]; p=0.020) was found to be another significant factor affecting the total knowledge score of HCPs. Overall, scoring of the correct responses revealed that nurses have better knowledge and understanding about influenza and the influenza vaccination (6.5 ± 0.8, p<0.001*), followed by pharmacists (6.3 ± 1.14) and physicians. In spite of the published guidelines and recommendations, a very low percentage of the healthcare professionals in our hospital were vaccinated against influenza, and

    Background Inappropriate use of antibiotics is a public health problem of great concern. Objective To evaluate knowledge of antibiotics, race, gender and age as independent risk factors for self-medication. Setting Residents and population from different regions of Saudi Arabia. Methods We conducted a cross sectional survey study among residents. Data were collected between June 2014 to May, 2015 from 1310 participants and data were recorded anonymously. The questionnaire was randomly distributed by interview of participants and included sociodemographic characteristics, antibiotics knowledge, attitudes and behavior with respect to antibiotics usage. Main outcome measure Population aggregate scores on questions and data were analyzed using univariate logistic regression to evaluate the influence of variables on self-prescription of antibiotics. Results The response rate was 87.7 %. A cumulative 63.6 % of participants reported to have purchased antibiotics without a prescription from pharmacies; 71.1 % reported that they did not finish the antibiotic course as they felt better. The availability of antibiotics without prescription was found to be positively associated with self-medication (OR 0.238, 95 % CI 0.17-0.33). Of those who used prescribed or non-prescribed antibiotics, 44.7 % reported that they kept left-over antibiotics from the incomplete course of treatment for future need. Interestingly, 62 % of respondents who used drugs without prescription agreed with the statement that antibiotics should be access-controlled prescribed by a physician. We also found significant association between storage, knowledge/attitudes and education. Conclusions The overall level of awareness on antibiotics use among residents in Saudi Arabia is low. This mandates public health awareness intervention programs to be implemented on the use of antibiotics.

    Background Inappropriate use of antibiotics is a public health problem of great concern. Objective To evaluate knowledge of antibiotics, race, gender and age as independent risk factors for self-medication. Setting Residents and population from different regions of Saudi Arabia. Methods We conducted a cross sectional survey study among residents. Data were collected between June 2014 to May, 2015 from 1310 participants and data were recorded anonymously. The questionnaire was randomly distributed by interview of participants and included sociodemographic characteristics, antibiotics knowledge, attitudes and behavior with respect to antibiotics usage. Main outcome measure Population aggregate scores on questions and data were analyzed using univariate logistic regression to evaluate the influence of variables on self-prescription of antibiotics. Results The response rate was 87.7 %. A cumulative 63.6 % of participants reported to have purchased antibiotics without a prescription from pharmacies; 71.1 % reported that they did not finish the antibiotic course as they felt better. The availability of antibiotics without prescription was found to be positively associated with self-medication (OR 0.238, 95 % CI 0.17-0.33). Of those who used prescribed or non-prescribed antibiotics, 44.7 % reported that they kept left-over antibiotics from the incomplete course of treatment for future need. Interestingly, 62 % of respondents who used drugs without prescription agreed with the statement that antibiotics should be access-controlled prescribed by a physician. We also found significant association between storage, knowledge/attitudes and education. Conclusions The overall level of awareness on antibiotics use among residents in Saudi Arabia is low. This mandates public health awareness intervention programs to be implemented on the use of antibiotics. PMID:27573719

    Iodine is a key component of the thyroid hormones, which are critical for healthy growth, development and metabolism. The UK population is now classified as mildly iodine-insufficient. Adequate levels of iodine during pregnancy are essential for fetal neurodevelopment, and mild iodine deficiency is linked to developmental impairments. In the absence of prophylaxis in the UK, awareness of nutritional recommendations during pregnancy would empower mothers to make the right dietary choices leading to adequate iodine intake. The present study aimed to: estimate mothers' dietary iodine intake in pregnancy (using a FFQ); assess awareness of the importance of iodine in pregnancy with an understanding of existing pregnancy dietary and lifestyle recommendations with relevance for iodine; examine the level of confidence in meeting adequate iodine intake. A cross-sectional survey was conducted and questionnaires were distributed between August 2011 and February 2012 on local (Glasgow) and national levels (online electronic questionnaire); 1026 women, UK-resident and pregnant or mother to a child aged up to 36 months participated in the study. While self-reported awareness about general nutritional recommendations during pregnancy was high (96 %), awareness of iodine-specific recommendations was very low (12 %), as well as the level of confidence of how to achieve adequate iodine intake (28 %). Median pregnancy iodine intake, without supplements, calculated from the FFQ, was 190 μg/d (interquartile range 144-256μg/d), which was lower than that of the WHO's recommended intake for pregnant women (250 μg/d). Current dietary recommendations in pregnancy, and their dissemination, are found not to equip women to meet the requirements for iodine intake.

    2014-01-01

    High salt intake increases the risk of hypertension and cardiovascular diseases. Given the role of knowledge as a determinant of food intake, this paper aims to review the current levels of salt knowledge and the association between salt knowledge and dietary salt intake and salt-related dietary practices in the general population. Twenty two studies were included in the review. In general, the studies showed consumers were able to identify the health risks associated with high salt intake. However, knowledge of recommended daily intakes, understanding of the relationships between salt and sodium and foods that contribute most salt to the diet were poor. Four of the five studies which examined the relationships between salt knowledge and salt-related dietary practices reported significant associations. Two important gaps in the current literature were identified. First, there is a need for a robustly validated tool to examine salt knowledge and its impact on salt intake. Second, a comprehensive salt knowledge assessment should include assessment of procedural, as well as declarative, knowledge. PMID:25470377

    Adults have been increasingly motivated to compete in recreational endurance sports events. Amateurs may lack a complete understanding of recommended strategies for handling heat and humidity, making heat-related illnesses increasingly possible. This is compounded by global climate change and increasing average surface and air temperatures, especially in urban areas of industrialized nations in Europe and North America that have hosted most events to date. We conducted an on-line, secure survey at the 2nd Annual ING Georgia Marathon and Half-Marathon in Atlanta, Georgia, in 2008. We included previously validated questions on participant socio-demographics, training locations, and knowledge and awareness of heat-related illnesses. Participants were aware of heat illnesses, and of heat stroke as a serious form of heat stress. However, the majority, across age and gender, did not understand the potential severity of heat stroke. Furthermore, 1-in-5 participants did not understand the concept of heat stress as a form of heat-related illness, and how heat stress may result from buildup of muscle-generated heat in the body. Adult recreational endurance athletes are another susceptible, vulnerable population sub-group for applied research and public health educational interventions, especially in urban areas of industrialized nations in Europe and North America.

    PURPOSE The purpose of this study was to evaluate the patients' knowledge on dental implants in a Turkish subpopulation. MATERIALS AND METHODS Five hundred twenty seven Turkish adults referred to Yeditepe University Faculty of Dentistry, Istanbul, Turkey, were presented with a questionnaire including 20 questions regarding the level of information and awareness about the dental implants. The data were collected and statistical analyses were performed with Chi square test to compare the descriptive data. RESULTS Among 527 subjects, 54% were female and 46% were male with a mean age of 42.2 years. The rate of patients' implant awareness was 27.7%. When the patients were questioned about the treatment options for rehabilitation of tooth missing, 60.9% of patients were informed about fixed partial denture, followed by conventional complete denture (32.5%) and removable partial denture (24.9%). Six percent reported that they were very well informed about the dental implants whereas 48.2% were poorly informed. The information sources of the implants were from the dentist (44.5%), printed media (31.6%) and friends and acquaintances (17.3%), respectively. Sixteen percent of the population believed that their implants would last forever. CONCLUSION The dentists should give more detailed information to the patients about dental implants and tooth-supported fixed partial dentures in the future. PMID:24843399

    A cross sectional study was conducted to assess the level of awareness and knowledge of common eye diseases (cataract, glaucoma, diabetic retinopathy and refractive errors) among 473 academic staff (non-medical faculties) of University Malaya. The awareness of cataract was in 88.2%, diabetic retinopathy in 83.5%, refractive errors in 75.3% and glaucoma in 71.5% of the study population. The knowledge about all the above common eye diseases was moderate, except presbyopia which was poor. Multivariate analysis revealed that females, older people, and those having family history of eye diseases were significantly more aware and more knowledgeable about the eye diseases. Health education about eye diseases would be beneficial to seek early treatment and prevent visual impairment in the society.

    Adolescents with type 1 diabetes typically receive clinical care every 3 months. Between visits, diabetes-related issues may not be frequently reflected, learned, and documented by the patients, limiting their self-awareness and knowledge about their condition. We designed a text-messaging system to help resolve this problem. In a pilot, randomized controlled trial with 30 adolescents, we examined the effect of text messages about symptom awareness and diabetes knowledge on glucose control and quality of life. The intervention group that received more text messages between visits had significant improvements in quality of life. PMID:25720675

    Objective Patients with severe sepsis or septic shock require timely, aggressive management to improve their outcomes, and early presentation of patients to the hospital may also be important. Thus, public awareness about sepsis may be important for improved outcomes. However, there are no studies regarding the public awareness of sepsis in the general Korean population. Therefore, the objective of this survey was to gain insight into the public awareness of sepsis. Methods Prospective paper-based and web-based surveys were issued between May and June 2013 to adults aged ≥18 years. Results A total of 1,081 participants responded to the survey (394 paper-based and 687 web-based). Mean age was 38.7±11.4 years, and 541 participants (50%) were men. Of the 1,081 participants, 831 (76.9%) had heard of the term “sepsis.” Of these participants, only 295 (35%) responded correctly regarding the definition of sepsis. However, 1,019 participants (94.3%) had heard of acute myocardial infarction, and 817 of these (80%) correctly defined acute myocardial infarction. Regarding stroke, 1,047 (96.9%) had heard of stroke, and 975 of these responded (93.1%) correctly to the definition of stroke. Conclusion There is poor public awareness about sepsis compared with that of acute myocardial infarction and stroke. This may limit the timely management of severe sepsis and septic shock.

    Background As social media becomes increasingly popular online venues for engaging in communication about public health issues, it is important to understand how users promote knowledge and awareness about specific topics. Objective The aim of this study is to examine the frequency of discussion and differences by race and ethnicity of cancer-related topics among unique users via Twitter. Methods Tweets were collected from April 1, 2014 through January 21, 2015 using the Twitter public streaming Application Programming Interface (API) to collect 1% of public tweets. Twitter users were classified into racial and ethnic groups using a new text mining approach applied to English-only tweets. Each ethnic group was then analyzed for frequency in cancer-related terms within user timelines, investigated for changes over time and across groups, and measured for statistical significance. Results Observable usage patterns of the terms "cancer", "breast cancer", "prostate cancer", and "lung cancer" between Caucasian and African American groups were evident across the study period. We observed some variation in the frequency of term usage during months known to be labeled as cancer awareness months, particularly September, October, and November. Interestingly, we found that of the terms studied, "colorectal cancer" received the least Twitter attention. Conclusions The findings of the study provide evidence that social media can serve as a very powerful and important tool in implementing and disseminating critical prevention, screening, and treatment messages to the community in real-time. The study also introduced and tested a new methodology of identifying race and ethnicity among users of the social media. Study findings highlight the potential benefits of social media as a tool in reducing racial and ethnic disparities. PMID:27227152

    The purpose of this study was to examine factors associated with human papillomavirus (HPV) knowledge and awareness, and HPV vaccination among White and Hispanic males and females. Differences in HPV knowledge, sources of information, vaccine awareness, vaccination status, and interest in vaccination were examined. A community sample was recruited from local health care clinics in a medium sized Midwestern city between May 2010 and December 2011. Participants (N = 507) were White (n = 243) and Hispanic, males (n = 202) and females between the ages of 15-30. Results indicate that White and female participants were significantly more likely to have heard of HPV, have higher levels of HPV knowledge, have been diagnosed with HPV, and be aware of the HPV vaccine for women. White and female participants were also more likely to have heard of HPV from their physician and were significantly more interested in receiving the HPV vaccine in the future. There was no effect of ethnicity on interest in the vaccine per a doctor's recommendation, however. Findings suggest that Whites and females have greater levels of HPV awareness and knowledge and that, while Hispanic participants are less likely than White participants to be told about the HPV vaccine from their provider, they may be equally receptive to such a recommendation.

    2016-01-01

    Background The burden of healthcare-associated infection worldwide is considerable, and there is a need to improve surveillance and infection control practices such as hand hygiene. Objectives The aims of this study were to explore direct care providers’ knowledge about infection prevention and hand hygiene, their attitudes regarding their own and others’ hand hygiene practices, and their ideas and advice for improving infection prevention efforts. Methods This exploratory study included interviews with direct care providers in three pediatric long-term care facilities. Two trained nurse interviewers conducted semistructured interviews using an interview guide with open-ended questions. Two other nurse researchers independently transcribed the audio recordings and conducted a thematic analysis using a strategy adapted from the systematic text condensation approach. Results From 31 interviews, four major thematic categories with subthemes emerged from the analysis: (a) hand hygiene products; (b) knowledge, awareness, perceptions, and beliefs; (c) barriers to infection prevention practices; and (d) suggested improvements. There was confusion regarding hand hygiene recommendations, use of soap or sanitizer, and isolation precaution policies. There was a robust “us” and “them” mentality between professionals. Discussion One essential driver of staff behavior change is having expectations that are meaningful to staff, and many staff members stated that they wanted more in-person staff meetings with education and hands-on, practical advice. Workflow patterns and/or the physical environment need to be carefully evaluated to identify systems and methods to minimize cross-contamination. Further studies need to evaluate if personal sized containers of hand sanitizer (e.g., for the pocket, attached to a belt or lanyard) would facilitate improvement of hand hygiene in these facilities.

    2012-01-01

    Objective To present a framework for combining implicit knowledge acquisition from multiple experts with machine learning and to evaluate this framework in the context of anemia alerts. Materials and Methods Five internal medicine residents reviewed 18 anemia alerts, while ‘talking aloud’. They identified features that were reviewed by two or more physicians to determine appropriate alert level, etiology and treatment recommendation. Based on these features, data were extracted from 100 randomly-selected anemia cases for a training set and an additional 82 cases for a test set. Two staff internists assigned an alert level, etiology and treatment recommendation before and after reviewing the entire electronic medical record. The training set of 118 cases (100 plus 18) and the test set of 82 cases were explored using RIDOR and JRip algorithms. Results The feature set was sufficient to assess 93% of anemia cases (intraclass correlation for alert level before and after review of the records by internists 1 and 2 were 0.92 and 0.95, respectively). High-precision classifiers were constructed to identify low-level alerts (precision p=0.87, recall R=0.4), iron deficiency (p=1.0, R=0.73), and anemia associated with kidney disease (p=0.87, R=0.77). Discussion It was possible to identify low-level alerts and several conditions commonly associated with chronic anemia. This approach may reduce the number of clinically unimportant alerts. The study was limited to anemia alerts. Furthermore, clinicians were aware of the study hypotheses potentially biasing their evaluation. Conclusion Implicit knowledge acquisition, collaborative filtering and machine learning were combined automatically to induce clinically meaningful and precise decision rules. PMID:22744961

    Objective: The aim of the study is to analyze the knowledge, attitude and practice of forensic odontology among dental practitioners in Chennai. Materials and Methods: A cross-sectional study was conducted in a sample of 322 dental practitioners in Chennai and data was collected by means of a questionnaire. Results: Twenty-one percent of the dental practitioners did not maintain dental records in their clinic/workplace, with only 12% of the practitioners maintaining complete records. Ninety-three percent of dental practitioners were not maintaining dental records for more than seven years. The significance of ante-mortem records in identifying deceased suspects was not known to 17% of the dental practitioners. Forty percent of the dental practitioners were not aware of child abuse and the actions to be taken. Dental age estimation was not known to 41% of the dental practitioners. Thirty-eight percent of the practitioners were unaware of the accurate method of individual identification. About 18% of the dental practitioners did not know the significance of bite mark patterns of the teeth. Ninety-three percent of the practitioners lacked formal training in collecting, evaluating and presenting dental evidence. Thirty percent of dental practitioners did not know they can testify as an expert witness in the court of law. Forty percent of the dental practitioners were unaware of identifying the age and gender of an individual in mass disasters. Conclusion: Our study revealed inadequate knowledge, poor attitude and lack of practice of forensic odontology prevailing among the dental practitioners in Chennai. PMID:22408322

    In 1992, the Indonesian CDC implemented strategies to control and prevent dengue fever (DF) by including community involvement to reduce larva breeding sites and a mass health education program. To contribute to this effort, we incorporated an educational component into a prospective study of DF conducted at two textile factories in Bandung. This education provided: a lecture on the signs and symptoms of dengue and ways to prevent the disease, posters in the health clinic at each factory and handouts given to each volunteer with an explanation of symptoms. Upon enrollment, each participant completed a questionnaire to gather demographic information. Additionally they were given a brief (non-standardized) test (PRE-test) of their dengue knowledge, which was verbally administered by the study physicians. Five questions (15 point system) were designed to assess the participant's ability to recognize and describe aspects of dengue in lay terms. The subject material included: the symptoms of acute DF, transmission of dengue virus, and basic steps for disease prevention. The same questionnaire was re-administered 18 months later (POST-test), and the results were compared. A total of 2,340 participants completed both the PRE- and POST-tests; there were 1,373 males and 967 females, median age 36 years (range 18-59). Only 0.3% of participants scored EXCELLENT (15-14 points) on the PRE-test whereas 8.4% scored EXCELLENT on the POST-test. Fewer participants scored VERY BAD (2-0 points) on the POST-test compared to the PRE-test (1.4% vs 4.0%). The average raw scores for the PRE- and POST-tests were 7.8 and 10.1, respectively. Improvement of individual scores correlated highly with educational level. No significant correlation was identified for gender, age, factory location or a diagnosis of dengue during the study. These findings demonstrate that our prospective study enhanced knowledge and awareness of dengue in the volunteers.

    About one in five Americans spends a considerable number of hours in school each week, and thus, is exposed to a variety of environmental agents. Community health nursing professionals require resources and specific training to acquire the environmental knowledge needed to raise personal and community awareness as an enhancement of their practice. Given limited resources for schools and local public health education initiatives, identifying and prioritizing environmental concerns comes before actions to prevent or reduce exposures. With the rise in prevalence of childhood asthma, of special concern are those agents within the school environment that may serve as asthma triggers. This pilot project, within a larger study in a large school district in metropolitan Atlanta, Georgia, developed and piloted an environmental health priorities survey with school nurses and other school staff about indoor and outdoor microenvironments relevant to school-aged children. Findings indicate that participants (N = 34) could prioritize environmental issues to inform future intervention activities (such as continuing education training), and distinguish predominantly indoor from typical outdoor exposure agents and their major sources.

    2015-10-01

    This study examined the relations among perceived and actual knowledge of phonemic awareness (PA), exposure to PA instruction during practicum, and self-efficacy for teaching PA in a sample of 54 teacher candidates (TCs) enrolled in a 1-year Bachelor of Education program in a Canadian university. It also assessed the effects of a brief multimedia-enhanced lecture on TCs' actual knowledge of PA and efficacy ratings. Prior to the lecture, teacher candidates' scores on the PA assessment were relatively low with a mean percentage correct of 56.3%. Actual knowledge was not significantly correlated with perceived knowledge or self-efficacy ratings. Perceived knowledge was significantly and positively correlated with efficacy ratings and students' rating of their exposure to PA instruction during their practicum experience. A path analysis revealed that the relationship between exposure to PA instruction and self-efficacy beliefs was mediated by perceived knowledge controlling for actual knowledge and general prior experience working with young children. Analyses also revealed that TCs made significant gains in self-efficacy as well as actual knowledge when re-assessed after the lecture with a mean post-lecture score of 71.4%. Written feedback from the TCs indicated that the digital video clips included in the lecture provided clarity regarding the type of instructional practices that teachers could use to support phonemic awareness development in children. Implications for practice and future research on teacher preparation are discussed.

    This study examined the relations among perceived and actual knowledge of phonemic awareness (PA), exposure to PA instruction during practicum, and self-efficacy for teaching PA in a sample of 54 teacher candidates (TCs) enrolled in a 1-year Bachelor of Education program in a Canadian university. It also assessed the effects of a brief multimedia-enhanced lecture on TCs' actual knowledge of PA and efficacy ratings. Prior to the lecture, teacher candidates' scores on the PA assessment were relatively low with a mean percentage correct of 56.3%. Actual knowledge was not significantly correlated with perceived knowledge or self-efficacy ratings. Perceived knowledge was significantly and positively correlated with efficacy ratings and students' rating of their exposure to PA instruction during their practicum experience. A path analysis revealed that the relationship between exposure to PA instruction and self-efficacy beliefs was mediated by perceived knowledge controlling for actual knowledge and general prior experience working with young children. Analyses also revealed that TCs made significant gains in self-efficacy as well as actual knowledge when re-assessed after the lecture with a mean post-lecture score of 71.4%. Written feedback from the TCs indicated that the digital video clips included in the lecture provided clarity regarding the type of instructional practices that teachers could use to support phonemic awareness development in children. Implications for practice and future research on teacher preparation are discussed. PMID:26024995

    Dilated cardiomyopathy (DCM) is a primary heart muscle disease characterized by a progressive dilation and dysfunction of either the left or both ventricles. The management of DCM is currently challenging for clinicians. The persistent lack of knowledge about the etiology and pathophysiology of this disease continues to determine important fields of uncertainty in managing this condition. Molecular cardiology and genetics currently represent the most crucial horizon of increasing knowledge. Understanding the mechanisms underlying the disease allows clinicians to treat this disease more effectively and to further improve outcomes of DCM patients through advancements in etiologic characterization, prognostic stratification and individualized therapy. Left ventricular reverse remodeling predicts a lower rate of major cardiac adverse events independently from other factors. Optimized medical treatment and device implantation are pivotal in inducing left ventricular reverse remodeling. Newly identified targets, such as angiotensin-neprilysin inhibition, phosphodiesterase inhibition and calcium sensitizing are important in improving prognosis in patients affected by DCM.

    2014-01-01

    Background A majority of Ethiopians rely on traditional medicine as their primary form of health care, yet they are in danger of losing both their knowledge and the plants they have used as medicines for millennia. This study, conducted in the rural town of Fiche in Ethiopia, was undertaken with the support of Southern Cross University (SCU) Australia, Addis Ababa University (AAU) Ethiopia, and the Ethiopian Institute of Biodiversity (EIB), Ethiopia. The aim of this study, which included an ethnobotanical survey, was to explore the maintenance of tradition in the passing on of knowledge, the current level of knowledge about medicinal herbs and whether there is awareness and concern about the potential loss of both herbal knowledge and access to traditional medicinal plants. Methods This study was conducted using an oral history framework with focus groups, unstructured and semi-structured interviews, field-walk/discussion sessions, and a market survey. Fifteen people were selected via purposeful and snowball sampling. Analysis was undertaken using a grounded theory methodology. Results Fourteen lay community members and one professional herbalist provided information about 73 medicinal plants used locally. An ethnobotanical survey was performed and voucher specimens of 53 of the plants, representing 33 families, were collected and deposited at the EIB Herbarium. The community members are knowledgeable about recognition of medicinal plants and their usage to treat common ailments, and they continue to use herbs to treat sickness as they have in the past. A willingness to share knowledge was demonstrated by both the professional herbalist and lay informants. Participants are aware of the threat to the continued existence of the plants and the knowledge about their use, and showed willingness to take steps to address the situation. Conclusion There is urgent need to document the valuable knowledge of medicinal herbs in Ethiopia. Ethnobotanical studies are imperative

    A documentary film on HIV was developed based on social cognitive theory and entertainment educational methods in an effort to increase awareness and encourage protective behavior change related to HIV among older adults. The documentary includes perspectives from racial- or ethnic-minority older adults who are living with HIV and those of health care providers, and was screened in several venues. Authors of this article conducted thematic content analysis of anonymous, written, open-ended responses from 341 film viewers (clinicians and laypeople) who described what they learned about HIV after viewing the film. Four key themes emerged from the analysis: (1) increased awareness about the epidemiology of HIV among older, minority groups and about sexuality among older people; (2) improved general HIV knowledge, including risk reduction strategies and details about HIV testing; (3) awareness of lack of sexual health education among health care providers, and that a call to action is needed; and (4) awareness that HIV reinfection can occur in certain circumstances with people who are already infected. Findings suggest that an educational documentary can be used to effectively increase awareness and knowledge about the impact of HIV among minority older adults, and may also encourage HIV prevention action steps by providers.

    Although there is a general lack of empirical evidence that advertising influences gambling participation, the regulation of gambling advertising is hotly debated among academic researchers, treatment specialists, lobby groups, regulators, and policymakers. This study contributes to the ongoing debate by investigating perceived impacts of gambling advertising in a sample of gamblers drawn from the general population in Norway (n = 6,034). Three dimensions of advertising impacts were identified, representing perceived impacts on (a) gambling-related attitudes, interest, and behavior ("involvement"); (b) knowledge about gambling options and providers ("knowledge"); and (c) the degree to which people are aware of gambling advertising ("awareness"). Overall, impacts were strongest for the knowledge dimension, and, for all 3 dimensions, the impact increased with level of advertising exposure. Those identified as problem gamblers in the sample (n = 57) reported advertising impacts concerning involvement more than recreational gamblers, and this finding was not attributable to differences in advertising exposure. Additionally, younger gamblers reported stronger impacts on involvement and knowledge but were less likely to agree that they were aware of gambling advertising than older gamblers. Male gamblers were more likely than female gamblers to report stronger impacts on both involvement and knowledge. These findings are discussed with regard to existing research on gambling advertising as well as their implications for future research and policy-making. (PsycINFO Database Record PMID:25730628

    Sickle cell trait (SCT; HbAS), the heterozygous state for the sickle cell allele of the beta globin gene, is carried by as many as 100 million individuals worldwide. Nigeria has the highest prevalence of SCT, impacting an estimated 25 % of adult population. This study was designed to assess timing of awareness, knowledge of SCT status and preferred method of education among parents of children with sickle cell disease (SCD). We conducted a cross-sectional survey of parents of children with SCD from June 2013-March 2014. Participants completed a 20-item questionnaire to assess (1) awareness of personal sickle cell genotype, (2) timing of awareness of personal sickle cell genotype, and (3) knowledge of SCT. One hundred and fifty-five participants completed the survey. Seventy-eight percent were females, and 87 % (135/155) were aware of their own sickle cell genotype. Timing of awareness varied as follows: following birth of a child with sickle cell disease (45 %); during marriage (21.5 %); school admission (9.6 %); during pregnancy (9.6 %); and other times (14 %). Approximately 35.5 % of participants thought that sickle cell trait was a mild form of sickle cell disease. Radio (43.9 %), informational community meetings (27.7 %), and television (21.9 %) were identified by participants as the most effective method of increasing sickle cell trait awareness. Innovative approaches are needed to increase the proportion of individuals who are aware of their own sickle cell genotype prior to having a child with sickle cell anemia in line with the Healthy People 2020 objective.

    The knowledge domain of anticipation is still in the process of being defined, and is therefore subject to controversies. Science was never an endeavour of consensus but rather of debate. This additional argument to the debate integrates awareness of the early Soviet/Russian contributions to a science of anticipation. From this awareness derives the understanding of why anticipation faces opposition from established viewpoints. This article ascertains that anticipation advances a fundamental view of the living. Within this view, anticipation is always expressed in action. Short of this definitory condition, anticipation fades into the grey mass of speculative predictive methods.

    In hearing children, reading skills have been found to be closely related to phonological awareness. We used several standardized tests to investigate the reading and phonological awareness skills of 27 deaf school-age children who were experienced cochlear implant users. Approximately two-thirds of the children performed at or above the level of their hearing peers on the phonological awareness and reading tasks. Reading scores were found to be strongly correlated with measures of phonological awareness. These correlations remained the same when we statistically controlled for potentially confounding demographic variables such as age at testing and speech perception skills. However, these correlations decreased even after we statistically controlled for vocabulary size. This finding suggests that lexicon size is a mediating factor in the relationship between the children's phonological awareness and reading skills, a finding that has also been reported for typically developing hearing children.

    Geoparks are the ideal destination for international study tours based on the sustainable tourism concept, in which the travel is conceived as an opportunity for sharing both scientific knowledge and intangible and tangible culture. Equally, they are the appropriate places for testing and practicing innovative educational strategies, shareable in an international context. The innovative idea of EduGeoPark project is to involve students and teachers in research activities in Geoparks, including sampling and digital mapping: practical field and laboratory activities for stimulating the geological interpretation of an unknown territory. An approach devoted to improve teamwork and problem solving competences. By means of a partnerships between the Rokua (Finland) and the Sesia-Val Grande (Italy) Geoparks, an exchange program for Secondary School's students started during 2014 (Vaala High School; I.I.S. Luigi Cobianchi High School in Verbania). The study and the visit of both territories was an opportunity for students to observe some relevant geological elements and processes that do not exist in their own country. Moreover, the hosting in families allowed them to feel the culture of the area. Teachers and staff of the Geoparks led field trips to the main geological and cultural attractions of both areas. During the activities, students used mobile devices (smartphone and tablet) and GPS to track field trips, to catch and gather georeferenced data and pictures. They acted as researchers, by using both digital and traditional tools: they observed, asked questions, gathered data, and made hypothesis. By sharing ideas, together with the local guides, they reconstructed the cultural and geological history of the area. Students appreciated the experience: not only they had the opportunity of visiting a different country, but also of deepening the geological awareness on their own territory. EduGeoPark project is opening the participation to other Geoparks, in order to

    The diseases caused by various types of Clostridium perfringens are critically reviewed in the light of current knowledge. Particular emphasis is placed on information concerning these diseases in Canadian livestock. There are two etiologically clearly-defined acute C. perfringens diseases recognized in Canada: hemorrhagic enteritis of the new born calf, caused by C. perfringens type C, and enterotoxemia of sheep, caused by type D. Clostridium perfringens type A may play a role as a secondary pathological agent in various disease conditions, such as necrotic enteritis of chickens. It may also cause wound infections and may provide a source for human food poisoning outbreaks. There appears to be a considerable lack of knowledge regarding the distribution of C. perfringens types, their pathogenesis, diagnosis and the incidence of diseases caused by this organism.

    Background: Swimming pool attendance exposes users to infection and chemical risks that could be largely reduced with the adoption of healthy behaviors. This study aims to investigate if the knowledge of swimming pool regulations and awareness of health risks can be associated with users’ health-related behaviors. Methods: A cross-sectional study was conducted using self-administered questionnaires to collect data from two different target groups of swimming users: 184 adults and 184 children/adolescents. The association between specific variables and patterns of behaviors and knowledge was assessed through multivariate logistic regression models. Results: Although more than 80% of both groups declared they knew the regulations, compliance with healthy behaviors was often unsatisfactory, especially in adolescents and youth. In the children/adolescents group, healthy behaviors significantly increased with the frequency of attendance per week. In both groups, compliance increased with educational level (of parents for children/adolescents), while no positive association was observed between viewing the regulations and adopting appropriate behaviors. In the adult group, a higher knowledge/awareness of health risks was related to decreased odds of at least one unhealthy behavior. Conclusions: Guaranteeing the public display of regulations in swimming facilities is not sufficient to promote and change health-related behaviors. Much more attention should be given to educational interventions aimed to increase knowledge of health risks and the awareness that bathers are directly responsible for their own well-being.

    INTRODUCTION Treatment of gout, specifically with colchicine, varies globally. Colchicine can be fatal due to its narrow therapeutic index and potential for interactions. In New Zealand, cases of intentional and unintentional colchicine overdose have been documented. AIMS To explore patients' knowledge on the use of gout medicines, and in particular their awareness of the maximum dose of colchicine, the dangers of colchicine overdose, and their opinions on restricting colchicine dispensing. The study also investigates where patients receive gout information. METHODS Thirty people with gout presenting to their regular gout clinic in Auckland currently or previously taking colchicine were invited to participate in a 30-min semi-structured interview. Data were analysed using a general inductive thematic approach. FINDINGS Overall, participants had a lack of knowledge regarding colchicine and used variable doses during an acute gout attack. Participants were unsure of the maximum dose of colchicine and several took more than prescribed. The prophylactic use of colchicine and allopurinol varied from 3 weeks to 15 years. Mixed views were reported on restricting colchicine supply. Most participants received gout information from their general practitioner (GP). CONCLUSION Poor understanding of colchicine contributed to inappropriate use and highlights the need for targeted patient education. Considerable inter-patient variability exists in the use of colchicine for acute gout, suggesting the efficacy of low dose regimens be explored. The length of adjunctive colchicine use, as part of a prophylaxis regimen, needs to be regularly reviewed and tailored to each patient. Further research is required on limiting the amount of colchicine dispensed. PMID:27477556

    The knowledge base regarding the production of geomagnetically induced currents (GIC) in power systems is briefly reviewed. The relationship between electric and magnetic fields for a layered earth is derived and used to calculate the electric fields produced in Quebec during the March 13, 1989, magnetic disturbance. Factors influencing the distribution of GIC throughout a system are also examined. The transfer functions of the earth and of power systems vary with frequency and so the relation between GIC and magnetic field variations is most appropriately examined in the frequency domain. Data collection requirements to allow this in future research are discussed.

    Addiction to psychoactive substances is a debilitating condition underpinned by the interplay of genetic and environmental factors. At present, a key challenge for research is to delineate how, at a molecular level, these influences become "biologically embedded," contributing to the onset and persistence of addictive behaviors. Recently, epigenetic processes that regulate gene expression have emerged as a potential mechanism of interest. In this commentary, we discuss the relevance of epigenetics to addiction research, starting with the current state of knowledge, what challenges we have yet to overcome, and what the future may hold in terms of research methodology and translational potential.

    Nausea is a subjective sensation, which often acts as a signal that emesis is imminent. It is a widespread problem that occurs as a clinical sign of disease or as an adverse effect of a drug therapy or surgical procedure. The mechanisms of nausea are complex and the neural pathways are currently poorly understood. This review summarises the current knowledge of nausea mechanisms, the available animal models for nausea research and the anti-nausea properties of commercially available anti-emetic drugs. The review also presents subjective assessment and scoring of nausea. A better understanding of the underlying mechanisms of nausea might reveal potential clinically useful biomarkers for objective measurement of nausea in species of veterinary interest.

    New knowledge advances our current understanding on the selection and application of the appropriate tools for assessing the state of the marine environment in the Southern European Seas (SES). Diminishing the lack of knowledge is a prerequisite for sound policy decisions. Although gaps and knowledge are fewer today, the health of marine and coastal ecosystems in the SES is under pressure and shows, in places, some signs of deterioration and declining quality. Overall, there is a lack of data accessibility and long time series in the SES, while in many cases poorly constrained processes cannot really support knowledge-based policy making (e.g. ecosystem functioning, climate change, fisheries management, etc.). New knowledge has to be produced and excellence must be promoted to support sustainable economic growth. At the same time, existing and new capacities have to be upgraded and increased in order to support sustainable convergence between SES countries. There are several gaps that have been identified and processes that have been poorly understood in the SES, mainly from research projects that have been working at basin level. The main research priorities that have been identified from the SeasERA Project for both, the Mediterranean and the Black Sea include: the climate change and its impacts, the hydrological cycle, the ventilation and the inter-basin coupling, the marine biodiversity and the provision of goods and services, the marine protected areas, the deep sea ecosystems, the biological invasions, the marine pollution and the ocean and human health, the renewable energy, the maritime transport, the fisheries and aquaculture activities and the biotechnology and the exploitation of marine resources for industrial application. More important, however, is the fact that the economic, the social and the scientific and the environmental challenges must be collectively tackled. They should have prioritisation and clear objectives as well as data sharing for

    Objectives Cervical cancer (CC) incidence and mortality among young women have been increasing in Japan. To develop effective measures to combat this, we assessed the feasibility of using a social networking site (SNS) to recruit a representative sample of young women to conduct a knowledge and attitude study about CC prevention via an internet-based questionnaire. Methods From July 2012 to March 2013, advertising banners targeting women aged 16 to 35 years in Kanagawa Prefecture were placed on Facebook in a similar manner as an Australian (AUS) study conducted in 16- to 25-year-olds in 2010 and on a homepage to advertise our CC advocacy activities. Eligible participants were emailed instructions for accessing our secure Web site where they completed an online survey including demographics, awareness, and knowledge of human papillomavirus (HPV) and CC. Data for the study population were compared with the general Japanese population and the AUS study. Results Among 394 women who expressed interest, 243 (62%) completed the survey, with 52% completing it via Facebook. Women aged 26 to 35 years, living in Yokohama City, with an education beyond high school, were overrepresented. Participants had high awareness and knowledge of HPV and CC, comparable with the AUS study participants. However, the self-reported HPV vaccination rate (22% among participants aged 16–25 years) and the recognition rate of the link between smoking and CC (31%) were significantly lower than in the AUS study (58% and 43%, respectively) (P < 0.05). Significant predictors of high knowledge scores about HPV included awareness of HPV vaccine (P < 0.001) and self-reported HPV vaccination (P < 0.05). Conclusions The SNS and homepage are efficient methods to recruit young women into health surveys, which can effectively be performed online. A nationwide survey using SNSs would be an appropriate next step to better understand the current lack of uptake of the national HPV vaccine program by young women

    Introduction Awareness and knowledge of treatment as prevention (TasP) was assessed among HIV-positive and HIV-negative gay, bisexual and other men who have sex with men (GBMSM) in Vancouver, Canada. Methods Baseline cross-sectional survey data were analyzed for GBMSM enrolled, via respondent-driven sampling (RDS), in the Momentum Health Study. TasP awareness was defined as ever versus never heard of the term “TasP.” Multivariable logistic regression identified covariates of TasP awareness. Among those aware of TasP, men's level of knowledge of TasP was explored through an examination of self-perceived knowledge levels, risk perceptions and short-answer definitions of TasP which were coded as “complete” if three TasP-related components were identified (i.e. HIV treatment, viral suppression and prevention of transmission). Information source was also assessed. Analyses were stratified by HIV status and RDS adjusted. Results Of 719 participants, 23% were HIV-positive, 68% Caucasian and median age was 33 (Interquartile range (IQR) 26,47). Overall, 46% heard of TasP with differences by HIV status [69% HIV-positive vs. 41% HIV-negative GBMSM (p<0.0001)]. In adjusted models: HIV-positive GBMSM were more likely to have heard of TasP if they were Canadian born, unemployed, not using party drugs and had higher CD4 counts; HIV-negative GBMSM were more likely to have heard of TasP if they were Caucasian (vs. Aboriginal), students, had higher education, a regular partner and multiple sexual partners. Among those aware of TasP 91% of HIV-positive and 69% of HIV-negative GBMSM (p<0.0001) felt they knew “a lot” or “a bit in general” about TasP; 64 and 41% (p=0.002) felt HIV treatment made the risk of transmission “a lot lower”; and 21 and 13% (p<0.0001) demonstrated “complete” TasP definitions. The leading information source was doctors (44%) for HIV-positive GBMSM and community agencies (38%) for HIV-negative GBMSM, followed by gay media for both

    2015-01-01

    Cyanobacteria are considered to be one of the most promising sources of new, natural products. Apart from non-ribosomal peptides and polyketides, ribosomally synthesized and post-translationally modified peptides (RiPPs) are one of the leading groups of bioactive compounds produced by cyanobacteria. Among these, cyanobactins have sparked attention due to their interesting bioactivities and for their potential to be prospective candidates in the development of drugs. It is assumed that the primary source of cyanobactins is cyanobacteria, although these compounds have also been isolated from marine animals such as ascidians, sponges and mollusks. The aim of this review is to update the current knowledge of cyanobactins, recognized as being produced by cyanobacteria, and to emphasize their genetic clusters and chemical structures as well as their bioactivities, ecological roles and biotechnological potential.

Apart from non-ribosomal peptides and polyketides, ribosomally synthesized and post-translationally modified peptides (RiPPs) are one of the leading groups of bioactive compounds produced by cyanobacteria. Among these, cyanobactins have sparked attention due to their interesting bioactivities and for their potential to be prospective candidates in the development of drugs. It is assumed that the primary source of cyanobactins is cyanobacteria, although these compounds have also been isolated from marine animals such as ascidians, sponges and mollusks. The aim of this review is to update the current knowledge of cyanobactins, recognized as being produced by cyanobacteria, and to emphasize their genetic clusters and chemical structures as well as their bioactivities, ecological roles and biotechnological potential.

  1. The Transition to High School: Current Knowledge, Future Directions

    PubMed Central

    2011-01-01

    In the American educational system, school transitions are frequent and predictable, but they can disrupt student functioning across developmental domains. How students experience school transitions has been a focus of research for some time, but the high school transition has received less attention, and the limited research often focuses on a particular developmental domain (e.g., academics and socioemotional well-being) to the exclusion of a more integrated model. This review relies on life course theory to establish an organizational framework for interpreting and connecting the diffuse and sometimes disparate findings on the high school transition, including adolescent developmental trajectories and the influence of social ties, changing sociocultural contexts, and stratification systems. Conclusions identify aspects for future inquiry suggested by current knowledge and the tenets of the life course perspective. PMID:21966178

    A national school-based human papillomavirus (HPV) vaccination programme has been available for 12-13 year old females in the UK since 2008, offering protection against HPV types 16 and 18, which are responsible for the majority of cervical cancer. Little is known about HPV knowledge in girls who have been offered the vaccine. Girls offered the school-based vaccine in the first routine cohort (n=1033) were recruited from 13 schools in London three years post-vaccination. Participants completed a questionnaire about HPV awareness, knowledge about HPV and the vaccine, and demographic characteristics including vaccine status. About a fifth of the girls reported they were unaware of the HPV infection. Among those who reported being aware of HPV (n=759) knowledge was relatively low. Approximately half of the participants knew that HPV infection causes cervical cancer, condoms can reduce the risk of transmission and that cervical screening is needed regardless of vaccination status. These results are helpful in benchmarking HPV-related knowledge in vaccinated girls and could be used in the development of appropriate educational messages to accompany the first cervical screening invitation in this cohort in the future.

  3. Awareness and perceptions on prevention, first aid and treatment of snakebites among Sri Lankan farmers: a knowledge practice mismatch?

    PubMed Central

    2014-01-01

    Background Snakebite is a global health problem associated with high morbidity and mortality. In Sri Lanka, snakebite is mainly an occupational health hazard associated with farming. Understanding awareness and perceptions in risk populations on the preventive measures, first aid and treatment for snakebite becomes pivotal in designing snakebite prevention and control programs. Using an investigator assisted self completed questionnaire, we assessed the awareness and perceptions of 176 part-time and full-time, Chena and paddy farmers from three dry zone districts of Sri Lanka where agriculture is the main economic activity. Findings High percentages of the participants were aware of practices that minimize snakebites in houses and outside, available treatments and most of the recommended first aid measures. Western medical treatment was preferred by the vast majority of the farmers over the traditional treatment. Conclusion Some of the protective measures that the farmers were aware of are not practiced generally in Sri Lanka, suggesting a knowledge-practice mismatch. We suggest studies to understand the effects of socioeconomic and cultural determinants on snakebite prevention in Sri Lanka. PMID:24847375

    Despite the importance of phonological awareness for the development of reading in alphabetic languages, little attention has been paid to its developmental origins. In this study, dual-process, latent growth models were used to examine patterns of bidirectional relations between letter knowledge and phonological awareness during preschool. The sample comprised 358 children (mean age=48.60 months, SD=7.26). Growth models were used to quantify the unique longitudinal relations between the initial level of each skill and growth in the other skill during the preschool year, after controlling for initial level of the same skill, vocabulary, age, and growth in the code-related skill being used as a predictor. Letter-name knowledge and phonological awareness were bidirectionally related; the initial level of each uniquely predicted growth in the other. Initial letter-sound knowledge and phonological awareness growth were not uniquely related, and vocabulary was not related to growth in phonological awareness. These findings extend the evidence of the relation between letter knowledge and phonological awareness to supra-phonemic tasks, indicating that this bidirectional relation begins at an earlier point in the development of phonological awareness than previously reported. In addition, these findings help to rule out general growth in letter knowledge and phonological awareness as an alternative explanation for the bidirectional relation between these two code-related skills.

    Background Ebola Virus Disease (EVD) is not new to the world. However, the West African EVD epidemic which started in 2014 evolved into the largest, most severe and most complex outbreak in the history of the disease. The three most-affected countries faced enormous challenges in stopping the transmission and providing care for all patients. Although Ghana had not recorded any confirmed Ebola case, social factors have been reported to hinder efforts to control the outbreak in the three most affected countries. This qualitative study was designed to explore community knowledge and attitudes about Ebola and its transmission. Methods This study was carried out in five of the ten regions in Ghana. Twenty-five focus group discussions (N = 235) and 40 in-depth interviews were conducted across the five regions with community members, stakeholders and opinion leaders. The interviews were recorded digitally and transcribed verbatim. Framework analysis was adopted in the analysis of the data using Nvivo 10. Results The results showed a high level of awareness and knowledge about Ebola. The study further showed that knowledge on how to identify suspected cases of Ebola was also high among respondents. However, there was a firm belief that Ebola was a spiritual condition and could also be transmitted through air, mosquito bites and houseflies. These misconceptions resulted in perceptions of stigma and discrimination towards people who may get Ebola or work with Ebola patients. Conclusion We conclude that although knowledge and awareness about Ebola is high among Ghanaians who participated in the study, there are still misconceptions about the disease. The study recommends that health education on Ebola disease should move beyond creating awareness to targeting the identified misconceptions to improve future containment efforts. PMID:26889683

    Although rove beetles (Paederus spp.) play a beneficial role as biological control agents to manage crop pests in agro-ecosystems, their high prevalence in human settings has elevated them to pest status in urban areas. Rove beetles neither bite nor sting, but accidental crushing on human skin causes them to release the toxin paederin, which causes dermatitis linearis. This review integrates currently available knowledge about the issues pertaining to Paederus infestation. For instance, the results of life history studies conducted under different food and temperature regimes are summarized, as they indicate how large a population can be in a habitat to cause massive and widespread infestation and illustrate the physiological traits required to maintain the population at the maximum level even under adverse conditions. In contrast to what is generally reported, we speculate that climatic factors do not necessarily result in Paederus dispersal in temperate regions; instead, habitat disturbance and site unsuitability may be the main factors that lead to massive dispersal to human settings. Factors such as whether dispersers are adaptable to xeric conditions in human settings, the probability that dispersed Paederus mate with the opposite sex, and whether dispersers have adequate nutrient intake to reproduce are considered to evaluate their potential to reproduce in human settings. Finally, the effectiveness of current commercial insecticides, challenges faced in managing infestations, and sustainable management practices are discussed to provide information for long-term control programs.

    Specific musical instruments can be a source of physical problems to their players. Based on reviews of the literature and personal experience, this paper summarizes current knowledge of problems affecting musicians who play instruments in the bassoon family (including the bassoon, contrabassoon, and several other instruments). Prevalence rates are higher in reports of surveys (ranging up to 86%), compared to clinical reports of patients seen and treated. Significant risk factors include young age, small body size, female gender, and use of large instruments. Problems unique to bassoonists are rare; most physical difficulties also are seen in general musculoskeletal clinical practices and in musicians playing all types of instruments. The left upper extremity is more commonly affected by overuse-related conditions in bassoonists. Non-playing-related problems are equally important for consideration (such as degenerative disorders and acute trauma), since they also affect practice and performance. Little experimental data exist to validate current and widely-held principles of treatment, rehabilitation, and prevention.

    Tendons mainly function as load-bearing tissues in the muscloskeletal system, transmitting loads from muscle to bone. Tendons are dynamic structures that respond to the magnitude, direction, frequency, and duration of physiologic as well as pathologic mechanical loads via complex interactions between cellular pathways and the highly specialized extracellular matrix. This paper reviews the evolution and current knowledge of mechanobiology in tendon development, homeostasis, disease, and repair. In addition, we review several novel mechanotransduction pathways that have been identified recently in other tissues and cell types, providing potential research opportunities in the field of tendon mechanobiology. We also highlight current methods, models, and technologies being used in a wide variety of mechanobiology research that could be investigated in the context of their potential applicability for answering some of the fundamental unanswered questions in this field. The article concludes with a review of the major questions and future goals discussed during the recent ORS/ISMMS New Frontiers in Tendon Research Conference held September 10–11, 2014 in New York City.

  18. Anatomy of the human mammary gland: Current status of knowledge.

    2013-01-01

    Mammary glands are unique to mammals, with the specific function of synthesizing, secreting, and delivering milk to the newborn. Given this function, it is only during a pregnancy/lactation cycle that the gland reaches a mature developmental state via hormonal influences at the cellular level that effect drastic modifications in the micro- and macro-anatomy of the gland, resulting in remodeling of the gland into a milk-secretory organ. Pubertal and post-pubertal development of the breast in females aids in preparing it to assume a functional state during pregnancy and lactation. Remarkably, this organ has the capacity to regress to a resting state upon cessation of lactation, and then undergo the same cycle of expansion and regression again in subsequent pregnancies during reproductive life. This plasticity suggests tight hormonal regulation, which is paramount for the normal function of the gland. This review presents the current status of knowledge of the normal macro- and micro-anatomy of the human mammary gland and the distinct changes it undergoes during the key developmental stages that characterize it, from embryonic life through to post-menopausal age. In addition, it discusses recent advances in our understanding of the normal function of the breast during lactation, with special reference to breastmilk, its composition, and how it can be utilized as a tool to advance knowledge on normal and aberrant breast development and function. Finally, anatomical and molecular traits associated with aberrant expansion of the breast are discussed to set the basis for future comparisons that may illuminate the origin of breast cancer.

    Pharmacogenomics (PGx) is the science that examines how an individual's genetic make-up affects the safety and efficacy of therapeutic drugs. PGx of response to cardiovascular (CV) medications is of the most successfully translated branches of PGx into the clinical workout. However, the clinical implementation of PGx of CV drugs is yet far beyond the growth of our understanding of the role of genetics in drug therapy. A considerable amount of efforts have been devoted by the regulatory agents like the food and drug administration (FDA) as well as the expert-based networks such as the Clinical Pharmacogenetics Implementation Consortium (CPIC) to overcome the existing barriers. This has been done, at least in part, for some of the most widely prescribed CV drugs, including clopidogrel, warfarin and simvastatin for which the PGx knowledge have been satisfactorily robust to provoke the CPIC to issue the guidelines for these drugs and the FDA to update the drugs' labeling, both strongly recommended the use of genotype-guided dosing for these medications, provided that the genetic data are available. For other drugs, however, studies have produced contradictory results and further large and well-designed clinical trials are required to expand and confirm the clinical utility of their PGx data. This review paper presents the current state of knowledge in the field of PGx of CV medications and describes the facilities assisting to the translation of PGx data into the clinical practice. Afterward, the existing body of PGx literature of the most-commonly used CV medications is comprehensively discussed.

    2015-01-01

    Background Sex trafficking has been a long-standing concern in Nepal. Very little has been achieved, however, in terms of actual reduction in the number of victims despite numerous anti-sex trafficking programs. This situation may be attributable to a lack of empirical evidence upon which to formulate anti-sexual trafficking interventions. This study aimed to assess sex trafficking-related knowledge, awareness and attitudes, and factors associated with sex trafficking awareness and attitudes towards the victims of sex trafficking and/or anti-sex trafficking campaigns among adolescent female students in Nepal. Methods A cross-sectional study was conducted between August–September 2013 among 292 adolescent female students (>10 years old) using systematic random sampling from three high schools in Sindhupalchowk district, Nepal. As an initial step, descriptive analyses were employed to characterize the data and multivariate logistic regression analyses were used to explore factors associated with sex trafficking awareness and related attitudes. Results Seventy-six percent of sampled students reported that they were aware of sex trafficking and 94.6% indicated media (i.e., radio or television) as the primary sources of their knowledge. Fifty-one percent mentioned relatives/friends as mediators of sex trafficking, 60.4% reported promise for better jobs as the primary attraction behind sex trafficking, and 48.6% mentioned adolescent females as the most vulnerable group for sex trafficking. Over half (56.8%) of the respondents had positive attitudes towards the victims of sex trafficking and/or anti-sex trafficking campaigns. Age (OR = 3.38, 95% CI:2.51–4.55), parents’ occupation (OR = 3.89, 95% CI:1.58–9.58), and having a radio/TV at home (OR = 6.67, 95% CI:3.99–9.54) were significantly associated with awareness, whereas being younger (OR = 0.67, 95% CI:0.55–0.79) and having joint-family (OR = 2.67, 95% CI:1.49–4.80) were significantly associated with

    Farmers' knowledge of IPM has been considered, as prerequisites to IPM adoption. In Iran the most prevalent extension method for training farmers in different fields like IPM is extension workshops. The main purpose of this study was to investigate workshop effectiveness to change farmer's knowledge of IPM through assessing and comparing farmer's knowledge of IPM. A survey was conducted among 90 farmers in Karaj City in 2007--08 that included 30 workshop participants, 30 farmers who had exposed to workshop participants, and 30 randomly selected farmers, which were outside of this community. A questionnaire including open and close ended questions was designed. Data was collected through personal structured interviews with respondents at their farms. The study found that workshop participants (10.38) had significantly higher knowledge scores than their non workshop counterparts (5.90). Data also showed very little diffusion of workshop-acquired knowledge from workshop participants to other community members.

    This paper applies interpretative phenomenological analysis as a tool to understand ways African American families discuss and make sense of their knowledge, awareness, and commitment of the organ donation process. African American families (n = 20) participated in self-directed conversations based on the organ donor model, which is grounded in the theory of reasoned action and the theory of motivated information management. Results indicate that the media strongly influences an individual's willingness to participate in the organ donation process and their commitment to further discuss their decisions with close family members. Greater attention should be given to cultural-specific campaigns to increase the number of African American donors. PMID:23560358

    Multiple-choice questionnaires devised to evaluate knowledge and awareness of testicular carcinoma and the practice of testicular self-examination (TSE) were distributed to 717 male soldiers and 200 military physicians in the Israeli army. Twenty-one percent of the soldiers had received explanations about the importance of TSE; 16% actually received instruction on TSE; yet only 2% practiced TSE regularly. Seventy percent of physicians had been taught how to examine testicles, but only 10% of physicians examined testicles in their routine physical exams. TSE was practiced most frequently among soldiers who had received instruction in the technique. Physicians should encourage their young male patients to practice TSE.

    Centipedes are among the oldest extant venomous predators on the planet. Armed with a pair of modified, venom-bearing limbs, they are an important group of predatory arthropods and are infamous for their ability to deliver painful stings. Despite this, very little is known about centipede venom and its composition. Advances in analytical tools, however, have recently provided the first detailed insights into the composition and evolution of centipede venoms. This has revealed that centipede venom proteins are highly diverse, with 61 phylogenetically distinct venom protein and peptide families. A number of these have been convergently recruited into the venoms of other animals, providing valuable information on potential underlying causes of the occasionally serious complications arising from human centipede envenomations. However, the majority of venom protein and peptide families bear no resemblance to any characterised protein or peptide family, highlighting the novelty of centipede venoms. This review highlights recent discoveries and summarises the current state of knowledge on the fascinating venom system of centipedes.

    Phocine distemper virus (PDV) was first recognized in 1988 following a massive epidemic in harbor and grey seals in north-western Europe. Since then, the epidemiology of infection in North Atlantic and Arctic pinnipeds has been investigated. In the western North Atlantic endemic infection in harp and grey seals predates the European epidemic, with relatively small, localized mortality events occurring primarily in harbor seals. By contrast, PDV seems not to have become established in European harbor seals following the 1988 epidemic and a second event of similar magnitude and extent occurred in 2002. PDV is a distinct species within the Morbillivirus genus with minor sequence variation between outbreaks over time. There is now mounting evidence of PDV-like viruses in the North Pacific/Western Arctic with serological and molecular evidence of infection in pinnipeds and sea otters. However, despite the absence of associated mortality in the region, there is concern that the virus may infect the large Pacific harbor seal and northern elephant seal populations or the endangered Hawaiian monk seals. Here, we review the current state of knowledge on PDV with particular focus on developments in diagnostics, pathogenesis, immune response, vaccine development, phylogenetics and modeling over the past 20 years.

A number of these have been convergently recruited into the venoms of other animals, providing valuable information on potential underlying causes of the occasionally serious complications arising from human centipede envenomations. However, the majority of venom protein and peptide families bear no resemblance to any characterised protein or peptide family, highlighting the novelty of centipede venoms. This review highlights recent discoveries and summarises the current state of knowledge on the fascinating venom system of centipedes. PMID:25723324

  12. Greenhouse gas emissions from grasslands: current knowledge and challenges

    Grassland ecosystems in a wider sense cover up to 40% of the global terrestrial surface (White et al. 2000). Knowledge about the exchange of the major greenhouse gases (GHG's, carbon dioxide - CO2, methane - CH4 and nitrous oxide - N2O) remains still limited for grasslands, while other ecosystems such as forests and peatlands (particularly systems storing large amounts of carbon) have been investigated more intensively. Here, we give an overview of the current state of GHG measurements in the alpine region of Europe (Switzerland, Austria) and the associated challenges in deriving annual GHG budgets as well as determining the abiotic and biotic variables driving the fluxes of CO2, CH4 and N2O. In particular the importance of management activities, that is fertilization and removal of above-ground biomass through harvesting and grazing, besides climate, the challenges when trying to measure small fluxes of CH4 and N2O using chamber or micrometeorological methods and the need of including winter emissions in annual balances will be stressed.

    Phocine distemper virus (PDV) was first recognized in 1988 following a massive epidemic in harbor and grey seals in north-western Europe. Since then, the epidemiology of infection in North Atlantic and Arctic pinnipeds has been investigated. In the western North Atlantic endemic infection in harp and grey seals predates the European epidemic, with relatively small, localized mortality events occurring primarily in harbor seals. By contrast, PDV seems not to have become established in European harbor seals following the 1988 epidemic and a second event of similar magnitude and extent occurred in 2002. PDV is a distinct species within the Morbillivirus genus with minor sequence variation between outbreaks over time. There is now mounting evidence of PDV-like viruses in the North Pacific/Western Arctic with serological and molecular evidence of infection in pinnipeds and sea otters. However, despite the absence of associated mortality in the region, there is concern that the virus may infect the large Pacific harbor seal and northern elephant seal populations or the endangered Hawaiian monk seals. Here, we review the current state of knowledge on PDV with particular focus on developments in diagnostics, pathogenesis, immune response, vaccine development, phylogenetics and modeling over the past 20 years.

    Introduction Traumatic dental injuries are one of the commonly encountered dental emergencies. Missing anterior tooth in children due to any injury can be a source of considerable physical and psychological discomfort for the child. The prognosis of some dental injuries depends to a great extent on parents’ knowledge of correct and prompt emergency measures. Aim The purpose of this cross-sectional study was to assess the knowledge, attitude and awareness level of parents regarding the emergency management of dental trauma and to find out the relation of the responses to social variables. Materials and Methods A total of 2000 parents were surveyed over a period of three months using a pretested close ended questionnaire prepared in English, Hindi as well as in the regional language which was divided into three parts: Part 1 contained questions on personal information, Part 2 on an imaginary case of trauma to assess their knowledge regarding trauma management and Part 3 related to their attitude towards dental trauma management education. The data was statistically analysed using descriptive and chi-square statistics. Results The overall knowledge of parents regarding emergency management of trauma was not satisfactory. Although most of the people were in favour of taking professional consultation for emergency management of trauma but most of them were unaware of the steps that need to be taken on their part so as to minimize complications and improve prognosis. Conclusion Educational campaigns are the need of the day to increase the knowledge of parents regarding emergency management of dental trauma.

  19. Prophylaxis and therapeutic potential of ozone in buiatrics: Current knowledge.

    PubMed

    Đuričić, Dražen; Valpotić, Hrvoje; Samardžija, Marko

    2015-08-01

    Ozone therapy has been in use since 1896 in the USA. As a highly reactive molecule, ozone may inactivate bacteria, viruses, fungi, yeasts and protozoans, stimulate the oxygen metabolism of tissue, treat diseases, activate the immune system, and exhibit strong analgesic activity. More recently, ozone has been used in veterinary medicine, particularly in buiatrics, but still insufficiently. Medical ozone therapy has shown effectiveness as an alternative to the use of antibiotics, which are restricted to clinical use and have been withdrawn from non-clinical use as in-feed growth promoters in animal production. This review is an overview of current knowledge regarding the preventive and therapeutic effects of ozone in ruminants for the treatment of puerperal diseases and improvement in their fertility. In particular, ozone preparations have been tested in the treatment of reproductive tract lesions, urovagina and pneumomovagina, metritis, endometritis, fetal membrane retention and mastitis, as well as in the functional restoration of endometrium in dairy cows and goats. In addition, the preventive use of the intrauterine application of ozone has been assessed in order to evaluate its effectiveness in improving reproductive efficiency in dairy cows. No adverse effects were observed in cows and goats treated with ozone preparations. Moreover, there is a lot of evidence indicating the advantages of ozone preparation therapy in comparison to the application of antibiotics. However, there are certain limitations on ozone use in veterinary medicine and buiatrics, such as inactivity against intracellular microbes and selective activity against the same bacterial species, as well as the induction of tissue inflammation through inappropriate application of the preparation.

    Renal transplantation is well established in the USA, Europe, India, and South Africa. However, it is still in its infancy in Nigeria. The objective of our study is to determine the knowledge, awareness, and acceptability of renal transplant among patients with end-stage renal disease (ESRD) and the factors which are responsible for the low level of transplantation in Ibadan, Nigeria. A 15-item pilot-tested questionnaire was administered to willing patients with ESRD seen at the medical outpatient clinic of the University Teaching Hospital, from January to December 2011. There was 81% participation rate of the respondents. Exactly 90.1% had formal education and 44% earned <50,000 naira per month. Seventy-nine percent of respondents was aware of renal transplantation, 70.4% would recommend it to others, and 66.7% accepted renal transplantation; 77.8% would maintain a close relationship with their donors. About 61.7% considered it very expensive, while 33.3% did not know the cost for transplantation. Of the reason for the low level of kidney transplantation in Nigeria, 39.5% had no idea and in 27.2% of the respondents, the fear of death by potential donors may be responsible. Eleven percent of responded that recipients had no money for kidney transplantation and another 11% thought the potential donors would like to be paid for donating their kidneys. Most of the respondents with ESRD were knowledgeable, aware of, and accepted renal transplantation as the next step to treat chronic renal failure. However, majority of these patients could not afford the cost for renal transplantation. PMID:27424696

    Recent disasters have shown that having clearly defined preventive procedures and decisions is a critical component that minimizes evacuation hazards and ensures a rapid and successful evolution of evacuation plans. In this context, we present our Situation-Aware System for enhancing Evacuation Plans (SASEP) system, which allows creating end-user business rules that technically support the specific events, conditions and actions related to evacuation plans. An experimental validation was carried out where 32 people faced a simulated emergency situation, 16 of them using SASEP and the other 16 using a legacy system based on static signs. From the results obtained, we compare both techniques and discuss in which situations SASEP offers a better evacuation route option, confirming that it is highly valuable when there is a threat in the evacuation route. In addition, a study about user satisfaction using both systems is presented showing in which cases the systems are assessed as satisfactory, relevant and not frustrating. PMID:24961212

The study was a descriptive cross-sectional design. Five hundred and fifty adolescents selected from public and private secondary schools in Ado Local Government Area of Ekiti State were recruited using a multistage sampling technique. Results. Four hundred and ninety-nine (92.4%) respondents had heard about sexually transmitted infections before, the three most important sources of information being electronic media (68.7%); teachers (68.1%); and print media (44.9%). Eighty percent of the respondents knew only one STI and the two most commonly mentioned ones were HIV/AIDS (78.0%) and gonorrhea (23.0%). More than 75% of the respondents knew the modes of transmission of STIs while some of them equally had misconceptions. The most important symptoms mentioned were weight loss (77.4%), painful micturition (68.9%), and genital ulcer (54.1%). On the whole, only 6.9% of the respondents had good knowledge of STIs; the rest had fair and poor knowledge. Conclusion. Secondary school adolescents in Ado Local Government Area have only a fair knowledge of sexually transmitted diseases. STI studies should be inculcated into the school curriculum and media publicity/enlightenment campaigns about them should be intensified. PMID:26345225

    Objective. To determine if exposure to an intervention course impacts pharmacy students’ mental health stigma (MHS) and mental health knowledge (MHK). Methods. A one-group pre/posttest intervention study of third-year pharmacy students (N=120) was conducted. Dependent variables were subdomains of MHS (recovery, safety, disclosure, separation, comfort) which were measured on a 5-point Likert scale (1=strongly disagree; 5=strongly agree). Mental health knowledge was measured with 10 true/false questions. The 2.5-hour intervention included presentations, videos, discussions, and active-learning exercises. Pre/posttests were administered, and data were analyzed using paired t tests and McNemar’s tests. Results. Among responding students (n=88; 73.3% response rate), the following stigma subdomains significantly decreased after the intervention for depression and schizophrenia: recovery, safety, separation, and comfort. Mental health knowledge scores significantly increased from 5.9 (1.5) to 6.8 (1.5). Conclusion. Pharmacy students’ MHS and MHK related to depression and schizophrenia can be improved through a brief and interactive anti-stigma intervention. PMID:27402983

    Increased consumption of fruits and vegetables is recommended to reduce chronic disease risk. Few studies have examined awareness of the current fruit and vegetable campaign in the United States, Fruits and Veggies-More Matters. This study assessed awareness of the Fruits and Veggies-More Matters campaign and knowledge of the 7-13 serving recommendation for fruit and vegetable consumption among adults, and determined whether these were associated with fruit and vegetable intake. Cross-sectional data from 3021 adults in the United States' National Cancer Institute's 2007 Food Attitudes and Behaviors Survey were analyzed. Few participants were aware of the Fruits and Veggies-More Matters campaign (2%) and the 7-13 recommendation (6%) for adults. More participants were aware of the former 5 A Day campaign (29%) and recommendation (30%). Thirty-nine percent reported consuming ≥5 servings of fruits and vegetables daily. Participants were more likely to consume ≥5 servings of fruits and vegetables/day if they were aware of the 5 A Day/Fruits and Veggies-More Matters campaign, and reported that the recommendation for adults was ≥5 servings/day. Findings suggest the need to increase awareness of the Fruits and Veggies-More Matters campaign, and the 7-13 recommendation among adults to support high fruit and vegetable intake.

    Prevention of infective endocardit s (IE) is mportant because it has a high mortalty rate.This study sets out to to gather information from patients who were at risk of developing IE of their knowledge of the need for prophylaxis for the disease. Forty-one black patients suffering from severe rheumatic heart disease (RHD) were interviewed. Only one patient (2.4%) was regularly visiting a dentist to maintain good oral health and only five (12.2%) had received advice about the need for antibiotic cover prior to dental extraction. The vast majority of patients (97.5%) visited a dentist only when driven by dental pain, 36.6 % had to travel for more than an hour to reach their nearest dentist, and 87.8% indicated that they brushed their teeth. It may be concluded that in this group of black patients with severe RHD there was a lack of knowledge of the need for and of measures recommended for prophylaxs against IE. In addition, attempts by the health care team to ensure good oral health and access to dental care for these patients were inadequate, if not non-existent. PMID:23951767

    The experience of collection of data on earthquake effects and diffusion of information to people, carried on through the site "haisentitoilterremoto.it" (didyoufeelit) managed by the Istituto Nazionale di Geofisica e Vulcanologia (INGV), has evidenced a constantly growing interest by Italian citizens. Started in 2007, the site has collected more than 520,000 compiled intensity questionnaires, producing intensity maps of almost 6,000 earthquakes. One of the most peculiar feature of this experience is constituted by a bi-directional information exchange. Every person can record observed effects of the earthquake and, at the same time, look at the generated maps. Seismologists, on the other side, can find each earthquake described in real time through its effects on the whole territory. In this way people, giving punctual information, receive global information from the community, mediated and interpreted by seismological knowledge. The relationship amongst seismologists, mass media and civil society is, thus, deep and rich. The presence of almost 20,000 permanent subscribers distributed on the whole Italian territory, alerted in case of earthquake, has reinforced the participation: the subscriber is constantly informed by the seismologists, through e-mail, about events occurred in his-her area, even if with very small magnitude. The "alert" service provides the possibility to remember that earthquakes are a phenomenon continuously present, on the other hand it shows that high magnitude events are very rare. This kind of information is helpful as it is fully complementary to that one given by media. We analyze the effects of our activity on society and mass media. The knowledge of seismic phenomena is present in each person, having roots on fear, idea of death and destruction, often with the deep belief of very rare occurrence. This position feeds refusal and repression. When a strong earthquake occurs, surprise immediately changes into shock and desperation. A

    Genomic tests are increasingly complex, less expensive, and more widely available with the advent of next-generation sequencing (NGS). We assessed knowledge and perceptions among genetic counselors pertaining to NGS genomic testing via an online survey. Associations between selected characteristics and perceptions were examined. Recent education on NGS testing was common, but practical experience limited. Perceived understanding of clinical NGS was modest, specifically concerning tumor testing. Greater perceived understanding of clinical NGS testing correlated with more time spent in cancer-related counseling, exposure to NGS testing, and NGS-focused education. Substantial disagreement about the role of counseling for tumor-based testing was seen. Finally, a majority of counselors agreed with the need for more education about clinical NGS testing, supporting this approach to optimizing implementation.

Study Selection: 36 studies that provided a quantitative measure of nutrition knowledge and described the measurement tool that was used were included. Data extraction: Participant description, questionnaire description, results (mean correct and responses to individual items), study quality, and questionnaire quality. Data synthesis: All studies were of neutral quality. Tools used to measure knowledge did not consider health literacy, were outdated with regards to consensus recommendations, and lacked appropriate and adequate validation. The current status of nutrition knowledge in athletes and coaches is difficult to ascertain. Gaps in knowledge also remain unclear, but it is likely that energy density, the need for supplementation, and the role of protein are frequently misunderstood. Conclusions: Previous reports of nutrition knowledge need to be interpreted with caution. A new, universal, up-to-date, validated measure of general and sports nutrition knowledge is required to allow for assessment of nutrition knowledge. PMID:27649242

    Depressive disturbances are common in patients with Parkinson’s disease (PD) and influence many other clinical aspects of the disease. In addition to causing inherent emotional distress, depressive disorders negatively impact quality of life, motor and cognitive deficits, functional disability, and other psychiatric comorbidities in patients with PD. Knowledge of the pathophysiology of PD depression remains limited. However, clinical studies demonstrate the efficacy of medications and psychotherapies for PD depression, underscoring the importance of their timely detection and concerted management. PMID:24190780

    Recent studies conducted in hydrogen sulfide (H2S) signaling have revealed potential importance of persulfides (RSSH) in redox biology. The inherent instability of RSSH makes these species difficult to study and sometimes controversial results are reported. In this review article we summarize known knowledge about both small molecule persulfides and protein persulfides. Their fundamental physical and chemical properties such as preparation/formation and reactivity are discussed. The biological implications of persulfides and their detection methods are also discussed. PMID:25969163

    Microbes are essential for every part of life on Earth. Numerous microbes inhabit the biosphere, many of which are uncharacterized or uncultivable. They form a complex microbial community that deeply affects against surrounding environments. Metagenome analysis provides a radically new way of examining such complex microbial community without isolation or cultivation of individual bacterial community members. In this article, we present a brief discussion about a metagenomics and the development of knowledge bases, and also discuss about the future trends in metagenomics.

    Type 1 diabetes mellitus (T1DM) has a wide presence in children and has a high mortality rates. The disease, if left unmanaged, poses various challenges to the patient and healthcare providers, including development of diabetic complications and thus decreasing the life expectancy of the affected child. The challenges of T1DM include awareness of the disease that is very poor among the general public and also in parents of T1DM children along with the health care professionals. The challenge of lack of awareness of T1DM can be met by increasing public awareness programs, conducting workshops for diabetes educators regarding T1DM in children, newsletters, CMEs, online courses, and by structured teaching modules for diabetes educators. Diagnosis of T1DM was a challenge a few decades ago but the situation has improved today with diagnostic tests and facilities, made available even in villages. Investigation facilities and infrastructure, however, are very poor at the primary care level, especially in rural areas. Insulin availability, acceptability, and affordability are also major problems, compounded by the various types of insulin that are available in the market with a varied price range. But effective use of insulin remains a matter of utmost importance. PMID:25941655

    This study aimed to determine the prevalence of dental fluorosis and its relationship to socioeconomic status, knowledge, and awareness among 12-year-old school children in Quetta, Pakistan. A cross sectional study was conducted among 349 school children aged 12 years in Quetta, Pakistan. By interviewing children and questionnaire for parents, socioeconomic status, knowledge, and awareness of fluorosis were collected. Dental fluorosis was examined using Dean's Index and Community Fluorosis Index. Prevalence of dental fluorosis was high (63.6%) among children with a majority of moderate and mild degree at 32.1% and 27.5%, respectively. The community fluorosis index was 1.6. While most children and parents had low-to-moderate levels of fluorosis knowledge, the majority of them worried about dental fluorosis. Most parents (84.8%) were uncertain about the condition of fluorosis in their children, and 87.4% did not know about fluorosis before. Dental fluorosis was found significantly associated with gender, family income, and parents' awareness (p ≤ 0.05). Multivariate analysis indicated that gender, and parent's awareness significantly predicted children's dental fluorosis. Knowledge and basic information regarding dental fluorosis is lacking in the community. Efforts in dissemination and communication about dental fluorosis should be increased in order to raise awareness and prevent the dental fluorosis in Pakistan.

  8. A neurocognitive theory of higher mental emergence: from anoetic affective experiences to noetic knowledge and autonoetic awareness.

    PubMed

    Vandekerckhove, Marie; Panksepp, Jaak

    2011-10-01

    This essay provides an overview of evolutionary levels of consciousness, with a focus on a continuum of consciousness: from primarily affective to more advanced cognitive forms of neural processing-from anoetic (without knowledge) consciousness based on affective feelings, elaborated by brain networks that are subcortical- and can function without neocortical involvement, to noetic (knowledge based) and autonoetic (higher reflective mental) processes that permits conscious awareness. An abundance of such mind-brain linkages have been established using standard neuropsychological and brain-imaging procedures. Much of the characterization of human mental landscapes has been achieved with long accepted psychometric procedures that often do not adequately tap the lived anoetic experiential phenomenological aspects of mind. Without an understanding of affective based anoetic forms of consciousness, an adequate characterization of the human mind may never be achieved. A full synthesis will require us to view mental-experiential processes concurrently at several distinct neurophysiological levels, including foundational affective-emotional issues that are best probed with cross-species affective neuroscience strategies. This essay attempts to relate these levels of analysis to the neural systems that constitute lived experience in the human mind. PMID:21530586

    A natural hazard that is expected to affect coastal areas in the near future is Sea-Level Rise (SLR) due to climate change. According to recent reports the eustatic sea-level rise caused by global warming will reach approximately 18-59 cm by the year 2100. Potential impacts of future sea-level rise include coastal erosion, frequent and intensified cyclonic activity and associated storm surge flooding that may affect the coastal zones, saltwater intrusion into groundwater aquifers, the inundation of ecologically significant wetlands, and threats to cultural and historical resources, as well as to infrastructure. The identification of sensitive sections of coasts and the assessment of potential impacts of SLR on these is therefore a fundamental, yet initial, step towards their protection. Greece has the most extensive coastline among all Mediterranean countries with most of the socio-economic activities concentrated along the coastal zone. Almost all big urban centres are coastal ones and the same stands for a great part of infrastructure (ports, airports, roads, electricity and telecommunications network etc). As a result, the impacts of a potential rise of the sea level are expected to seriously affect the entire country. The paper examines the vulnerability to SLR of coastal zones in Greece; however its main focus is how knowledge can lead to policy making and the protection of coastal areas. The main actors in respect to protection from SLR in Greece are identified and there is an attempt to pin point how the knowledge is communicated and shared between them. Barriers, bridges and gaps are detected as regards how information and knowledge lead to risk awareness and finally to the implementation of protection policies. A main finding of the paper is that SLR risk is far from becoming a policy priority in Greece, although steps are taken for addressing impacts attributed to SLR such as coastal erosion. In order to address this risk, there are many potential

    In recent years, studies on the mucosal immunity in fish species have shown much progress. Although there are some organs such as skin, gills, and gut are directly associated with the mucosal immunity of fish species, this mini review emphasizes the general knowledge on the role and production figures of skin mucus and factors affecting the secretion of skin mucus of fish species. As the skin mucus of fish species is the first defense line for protection against invading microorganisms such as pathogens (bacteria, virus), parasites, etc., the information for understanding the roles of the skin mucus is very important. Furthermore, the information in the review will shed light on the development of high quality aquafeeds for the sustainable aquaculture field as well. PMID:26779184

(1963); C R Hebd Seances Acad Sci 257:3098-3102]. 5p- is caused by partial or total deletion of the short arm of chromosome 5. The most recognizable phenotype is characterized by a high-pitched cry, dysmorphic features, poor growth, and developmental delay. This report reviews 5p- disorders and their molecular basis. Hemizygosity for genes located within this region have been implicated in contributing to the phenotype. A review of the genes on 5p which may be dosage sensitive is summarized. Because of the growing knowledge of these specific genes, future directions to explore potential targeted therapies for individuals with 5p- are discussed. © 2015 Wiley Periodicals, Inc.

    2011-01-01

    The impact of genomics and pharmacogenomics in the current arena of clinical oncology is well-established. In breast cancer, mutations in the BRCA1 and BRCA2 genes have been well-characterized to carry a high risk of the disease during a woman's lifespan. However, these high risk genes contribute to only a small proportion of the familial cases of breast cancer. Hence, further efforts aimed to study the contribution of genetic mutations in other genes, including the estrogen receptor gene, TP53, CYP19, and mismatch repair genes to further investigate the genetic component of breast cancer. Multiple pharmacogenomic studies have previously linked genetic variants in known pathways with treatment response in cancer patients. Currently, polymorphisms in drug metabolizing enzymes, efflux transporters, as well as, drug targets have shown correlations to variations in response and toxicity to commonly prescribed chemotherapeutic treatments of breast cancer. CYP2D6 variants have been correlated with tamoxifen response and interindividual variability seen. An emerging application of cancer genetics and pharmacogenetics involves the use of inherited or acquired genetic abnormalities to predict treatment toxicity or outcomes. Recently, methods that involve the scanning of entire genomes for common variants have begun to influence studies of cancer causation. Currently, treatment individualization for breast cancer can take place on the basis of few molecular targets including the estrogen receptor and the overexpression of the HER2 receptor. Overall, the current review summarizes the recent findings in the genetic and pharmacogenetic research of breast cancer and the advances made in personalization of treatment. PMID:21875255

    Seizures are the most common neurological emergencies in the neonatal period and are associated with poor neurodevelopmental outcomes. Seizures affect up to five per 1000 term births and population-based studies suggest that they occur even more frequently in premature infants. Seizures are a sign of an underlying cerebral pathology, the most common of which is hypoxic-ischaemic encephalopathy in term infants. Due to a growing body of evidence that seizures exacerbate cerebral injury, effective diagnosis and treatment of neonatal seizures is of paramount importance to reduce long-term adverse outcomes. Electroencephalography is essential for the diagnosis of seizures in neonates due to their subtle clinical expression, non-specific neurological presentation and a high frequency of electro-clinical uncoupling in the neonatal period. Hypoxic-ischaemic encephalopathy may require neuroprotective therapeutic hypothermia, accompanying sedation with opioids, anticonvulsant drugs or a combination of all of these. The efficacy, safety, tolerability and pharmacokinetics of seven anticonvulsant drugs (phenobarbital, phenytoin, levetiracetam, lidocaine, midazolam, topiramate and bumetanide) are reviewed. This review is focused only on studies reporting electrographically confirmed seizures and highlights the knowledge gaps that exist in optimal treatment regimens for neonatal seizures. Randomised controlled trials are needed to establish a safe and effective treatment protocol for neonatal seizures. PMID:26943929

    A keystone of the competitive strategy in health insurance markets is the assumption that "consumers" can make informed choices based on the costs and quality of competing health plans, and that selection effects are not large. However, little is known about how individuals use information other than price in the decision making process. This review summarizes the state of knowledge about how individuals make choices among health plans and outlines an agenda for future research. We find that the existing literature on health plan choice is no longer sufficient given the widespread growth and acceptance of managed care, and the increased proportion of consumers' income now going toward the purchase of health plans. Instead, today's environment of health plan choice requires better understanding of how plan attributes other than price influence plan choice, how other variables such as health status interact with plan attributes in the decision making process, and how specific populations differ from one another in terms of the sensitivity of their health plan choices to these different types of variables.

Material and methods The participants were asked to answer to 14 questions of a questionnaire about age, education, economic and social condition, knowledge about PCa, state of being examined and their related factors. According to demographic characteristics of the participants, levels of awareness about PCa, sources of information, affecting factors and their interrelationships were examined. Two groups were formed according to age (<60 years, >60 years) and variations according to ages were investigated. Results Two hundred and ninety-three men with an average age of 57 years (range 40–85) were included in the study. Our findings showed that 68.3% of the participants were thinking that PCa is a frequently seen disease, 88.4% were thinking that it can be treated and 62.8% of men specified that their information sources are doctors. We also found that 60.8% of the participants had not undergone prostate examination and prostate specific antigen (PSA) control. The most reason for not having annual examinations was (44.4%) “negligence”. Significantly greater number of men with higher education (high school/university) were highly informed about PCa (p=0.037). Check-up rates were statistically significantly higher among men with intermediate income (p=0.041). Curability of PCa diagnosed at an early stage was acknowledged by statistically higher number of individuals under the age 60 (p<0.05). Health control, prostate examination and/or PSA control rates were higher in men with a family history of PCa and in the group of >60 years. Conclusion Although PCa has a high prevalence and mortality rates, personal and social information and sensitivity levels must be increased as it can be treated if diagnosed at an early stage.

    Alzheimer's disease (AD) is highly heritable, but genetically complex. Recently, three large-scale genome-wide association studies have made substantial breakthroughs in disentangling the genetic architecture of the disease. These studies combined include data from over 43 000 independent individuals and provide compelling evidence that variants in four novel susceptibility genes (CLU, PICALM, CR1, BIN1) are associated with disease risk. These findings are tremendously exciting, not only in providing new avenues for exploration, but also highlighting the potential for further gene discovery when larger samples are analysed. Here we discuss progress to date in identifying risk genes for dementia, ways forward and how current findings are refining previous ideas and defining new putative primary disease mechanisms.

    Aortic valve bioprostheses are commonly implanted in the current era (also in younger patients) as they may obviate the need for anticoagulation while providing better hemodynamic performance and a more favorable quality of life. The steady increase in the use of biological valves has prompted the development of several different models of conventional stented bioprostheses. At present, there are four main types of stented aortic bioprostheses that compete in the market: the LivaNova Crown PRT (LivaNova Group, Burnaby, Canada), the St. Jude Medical Trifecta (St. Jude Medical, St. Paul, MN, USA), the Carpentier-Edwards Perimount Magna Ease (Edwards Lifesciences, Irvine, CA, USA), and the Medtronic Mosaic Ultra (Medtronic, Inc., Minneapolis, MN, USA). The purpose of this review is to describe the features of these bioprosthetic valve models and to compare the data provided by the manufacturers with those derived from the available literature.

    Studies relying on looking-time measures have found evidence of a far more precocious understanding of hidden objects than Piaget originally described. However, there is now a heated controversy surrounding the results from looking-time studies - do they constitute any evidence of a conceptual or explicit understanding of objects? Moreover, even within the looking-time paradigm, young infants show rapid changes in their understanding of what constitutes a legitimate occlusion event, and in their ability to use feature information to individuate or keep track of the number of hidden objects. The picture that emerges from these studies is that young infants have a limited and sometimes fragmented understanding of hidden objects. We suggest that computational modelling could help provide a coherent account of the emergence of object-directed behaviours in infancy, although the fit between current models and existing data remains poor.

    Patients with adult-onset autoimmune diabetes have less Human Leucocyte Antigen (HLA)-associated genetic risk and fewer diabetes-associated autoantibodies compared with patients with childhood-onset Type 1 diabetes. Metabolic changes at diagnosis reflect a broad clinical phenotype ranging from diabetic ketoacidosis to mild non-insulin-requiring diabetes, also known as latent autoimmune diabetes of the adult (LADA). This latter phenotype is the most prevalent form of adult-onset autoimmune diabetes and probably the most prevalent form of autoimmune diabetes in general. Although LADA is associated with the same genetic and immunological features as childhood-onset Type 1 diabetes, it also shares some genetic features with Type 2 diabetes, which raises the question of genetic heterogeneity predisposing to this form of the disease. The potential value of screening patients with adult-onset diabetes for diabetes-associated autoantibodies to identify those with LADA is emphasized by their lack of clinically distinct features, their different natural history compared with Type 2 diabetes and their potential need for a dedicated management strategy. The fact that, in some studies, patients with LADA show worse glucose control than patients with Type 2 diabetes, highlights the need for further therapeutic studies. Challenges regarding classification, epidemiology, genetics, metabolism, immunology, clinical presentation and treatment of LADA were discussed at a 2014 workshop arranged by the Danish Diabetes Academy. The presentations and discussions are summarized in this review, which sets out the current ideas and controversies surrounding this form of diabetes. What’s new? Latent autoimmune diabetes of the adult (LADA) is an autoimmune diabetes defined by adult-onset, presence of diabetes associated autoantibodies, and no insulin treatment requirement for a period after diagnosis. Immunologically, glutamic acid decarboxylase 65 autoantibodies are by far the most

    Primary infection with the human cytomegalovirus (CMV) occurs in 1-4% of pregnancies. The rates of maternal-fetal CMV transmissions are around 25, 36, 41, and 66%, for infections occurring in the peri-conceptional weeks, first, second, and third trimester of pregnancy, respectively. On the other hand, the severity of fetal organ damage and dysfunction diminishes with increasing gestational age. Congenitally CMV-infected newborns may have neurosensory impairments like mental retardation, cerebral palsy, epilepsy, progressive hearing loss or visual defects, or even may have a fatal outcome. In in-vitro experiments, CMV specific neutralizing IgG antibodies - which are abundant in CMV specific hyperimmune globulin (HIG) products - inhibited the entry of the virus into target cells and hampered viral cell-to-cell spread. This article provides a brief overview on the epidemiology and diagnostic tools in congenital CMV infection. It also concisely summarizes the currently available study results on the safety and effectiveness of HIG treatment. Accordingly, in clinical studies HIG administration to expectant mothers following primary CMV infection (prophylactic use) was shown to lower the risk of maternal-fetal transmission of CMV compared to untreated controls. HIG was also able to ameliorate the disease sequelae in evidently infected fetuses (therapeutic use), as demonstrated by the regression or even resolution of sonographic pathologies including placental inflammation.

    Neurodegenerative diseases are going to increase as the life expectancy is getting longer. The management of neurodegenerative diseases such as Alzheimer's disease (AD) and other dementias, Parkinson's disease (PD) and PD related disorders, motor neuron diseases (MND), Huntington's disease (HD), spinocerebellar ataxia (SCA), and spinal muscular atrophy (SMA), is mainly addressed to motor and cognitive impairment, with special care to vital functions as breathing and feeding. Many of these patients complain of painful symptoms though their origin is variable, and their presence is frequently not considered in the treatment guidelines, leaving their management to the decision of the clinicians alone. However, studies focusing on pain frequency in such disorders suggest a high prevalence of pain in selected populations from 38 to 75% in AD, 40% to 86% in PD, and 19 to 85% in MND. The methods of pain assessment vary between studies so the type of pain has been rarely reported. However, a prevalent nonneuropathic origin of pain emerged for MND and PD. In AD, no data on pain features are available. No controlled therapeutic trials and guidelines are currently available. Given the relevance of pain in neurodegenerative disorders, the comprehensive understanding of mechanisms and predisposing factors, the application and validation of specific scales, and new specific therapeutic trials are needed.

    The oxytocin (OT) system is involved in various aspects of social cognition and prosocial behavior. Specifically, OT has been examined in the context of social memory, emotion recognition, cooperation, trust, empathy, and bonding, and—though evidence is somewhat mixed-intranasal OT appears to benefit aspects of socioemotional functioning. However, most of the extant data on aging and OT is from animal research and human OT research has focused largely on young adults. As such, though we know that various socioemotional capacities change with age, we know little about whether age-related changes in the OT system may underlie age-related differences in socioemotional functioning. In this review, we take a genetic-neuro-behavioral approach and evaluate current evidence on age-related changes in the OT system as well as the putative effects of these alterations on age-related socioemotional functioning. Looking forward, we identify informational gaps and propose an Age-Related Genetic, Neurobiological, Sociobehavioral Model of Oxytocin (AGeNeS-OT model) which may structure and inform investigations into aging-related genetic, neural, and sociocognitive processes related to OT. As an exemplar of the use of the model, we report exploratory data suggesting differences in socioemotional processing associated with genetic variation in the oxytocin receptor gene (OXTR) in samples of young and older adults. Information gained from this arena has translational potential in depression, social stress, and anxiety-all of which have high relevance in aging—and may contribute to reducing social isolation and improving well-being of individuals across the lifespan.

    Within the past 4 years, poliomyelitis outbreaks associated with circulating vaccine-derived polioviruses (cVDPVs) have occurred in Hispaniola (2000-01), the Philippines (2001), and Madagascar (2001-02). Retrospective studies have also detected the circulation of endemic cVDPV in Egypt (1988-93) and the likely localized spread of oral poliovirus vaccine (OPV)-derived virus in Belarus (1965-66). Gaps in OPV coverage and the previous eradication of the corresponding serotype of indigenous wild poliovirus were the critical risk factors for all cVDPV outbreaks. The cVDPV outbreaks were stopped by mass immunization campaigns using OPV. To increase sensitivity for detecting vaccine-derived polioviruses (VDPVs), in 2001 the Global Polio Laboratory Network implemented additional testing requirements for all poliovirus isolates under investigation. This approach quickly led to the recognition of the Philippines and Madagascar cVDPV outbreaks, but of no other current outbreaks. The potential risk of cVDPV emergence has increased dramatically in recent years as wild poliovirus circulation has ceased in most of the world. The risk appears highest for the type 2 OPV strain because of its greater tendency to spread to contacts. The emergence of cVDPVs underscores the critical importance of eliminating the last pockets of wild poliovirus circulation, maintaining universally high levels of polio vaccine coverage, stopping OPV use as soon as it is safely possible to do so, and continuing sensitive poliovirus surveillance into the foreseeable future. Particular attention must be given to areas where the risks for wild poliovirus circulation have been highest, and where the highest rates of polio vaccine coverage must be maintained to suppress cVDPV emergence.

    Vitamin D, i.e., 1.25(OH)2D, is an essential factor, not only of homeostasis of calcium and phosphorus, but also of cell proliferation, differentiation and apoptosis, immune and hormonal regulation, as well as other body processes.Thus, its optimal presence in the body is of exceptional significance for health, both of children, as well as adults and elderly persons. Today, it is known that the lack of vitamin D, besides having negative effects on the skeleton and teeth, also contributes to the development of various malignancies, primarily of the large bowel, prostate and breasts, as well as of autoimmune and allergic diseases, diabetes mellitus type II, arterial hypertension and others. Considered from the biological aspect, physiological requirements in vitamin D are achieved by cutaneous synthesis from 7-dehydrocholesterol during sun exposure, while, except rarely, it is very scarce in food. Having in mind extensive evidence that sun exposure presents a high risk for the development of skin malignancies, primarily melanoma, it is clear that humans are deprived of the natural and basic source of vitamin D. In accordance, as well as based on numerous epidemiological studies showing the increase of diseases, in the basis of which vitamin D deficiency plays the important role, next led to the recommended dietary allowance of vitamin D, regardless of age. According to current attitudes, it is recommended that the daily dietary allowances of vitamin D, i.e., the quantity of oral intake that would safely cover the optimal body requirements should be 400 IU for ages 0-18 years, 600 IU for ages 19-70 years and 800 IU for persons aged over 70 years.

    This review briefly summarizes the latest findings on reproductive endocrinology of Atlantic hagfish (Myxine glutinosa) and implications for fisheries management. In response to a major decline or collapse of the fisheries (groundfish and anadromous species) industry in the Northeast, species that were once considered alternative or underutilized have and are being identified that may be suitable for commercial harvest, one such example is the hagfish. Hagfish in recent years have been sought after as valuable fish not only for their flesh, but also their skin. Currently, there are no regulations governing the harvesting of hagfish along the East Coast. There has been little to no information of the life history of hagfish including growth rate, age determination, reproductive biology, life span, and larval size at hatching. Thus, the level at which a sustainable fisheries for this species can be maintained is unknown. In some parts of the world, hagfish stocks are being depleted due to overfishing. In order for fisheries management to manage its hagfish stocks and develop a sustainable commercial hagfish fishery, critical information is needed to assist in determining the optimal use of this valuable resource.Key elements of the reproductive system have not been elucidated in hagfish. However, there is new evidence from recent reproductive studies that Atlantic hagfish may have a seasonal reproductive cycle. These data include seasonal changes in gonadotropin-releasing hormone (GnRH), gonadal steroids, estradiol and progesterone, corresponding to gonadal reproductive stages along with the putative identity of a functional corpus luteum. This newly acquired data may provide important information to fisheries managers of the East Coast.

  18. Diagnosis and management of chronic pancreatitis: current knowledge.

    Ammann, Rudolf W

    2006-03-18

    This paper reviews the current literature on chronic pancreatitis (CP). Despite marked progress in diagnostic tools, predominately imaging methods, no consensus has been reached on the nomenclature of CP, ie diagnosis, classification, staging, pathomechanisms of pain and its optimal treatment. A major problem is that no single reliable diagnostic test exists for early-stage CP except histopathology (rarely available). This stage is characterised typically by recurrent acute pancreatitis +/- necrosis (eg pseudocysts). Acute pancreatitis is a well-defined condition caused in 80% of cases by gallstones or alcohol abuse. Alcoholic pancreatitis, in contrast to biliary pancreatitis, progresses to CP in the majority of patients. However, a definite CP-diagnosis is often delayed because progressive dysfunction and/or calcification, the clinical markers of CP, develop on average 5 years from disease onset. The progression rate is variable and depends on several factors eg aetiology, smoking, continued alcohol abuse. Repeated function testing eg by the faecal elastase test, is the best alternative for histology to monitor progression (or non-progression) of suspected (probable) to definite CP. The pathomechanism of pain in CP is multifactorial and data from different series are hardly comparable mainly because insufficient data of the various variables ie diagnosis, classification, staging of CP, pain pattern and presumptive pain cause, are provided. Pain in CP is rarely intractable except in the presence of cancer, opiate addiction or extra-pancreatic pain causes. Local complications like pseudocysts or obstructive cholestasis are the most common causes of severe persistent pain which can be relieved promptly by an appropriate drainage procedure. Notably, partial to complete pain relief is a common feature in 50-80% of patients with late-stage CP irrespective of surgery and about 50% of CP-patients never need surgery (or endoscopic intervention).

    Background: Flexibility of digital photography enables it to be an integral part of pathology practice. An assessment of guidelines of imaging is essential for proper usage of photographs. Objectives: The purpose of the study was to assess awareness of oral pathologists about various aspects of medical photography. Methods: Questionnaire based on the availability of facilities, usage, technical details and ethical issues of medical photography was sent to postgraduate students and teaching faculties of Oral Pathology in various localities in India. Results: Photographs were taken mostly for the purposes of publication, medical documentation and education. Significant number of postgraduate students and faculties of Oral Pathology didn’t receive any training or hadn’t gone through any publications/books (P = 0.000) about medical photography. Consent for patient photography was taken by significant number of respondents (P = 0.000) but in a verbal form. Majority of people used image editing software, but 19.0% of faculties and 21.1% of postgraduate students were unaware of deleterious effect of image editing. Firm and sensible instructions concerning image storage, sharing and accessibility were not yet created. Conclusion: This survey drew attention towards lack of proper understanding about the technical details, medical protocols and ethical issues related to medical photography. These findings recommend implementation of basic training for medical photography and policy for image management for students and faculties in every health care institution. PMID:26604489

    Trauma and immunosuppressed patients are at risk for cytomegalovirus (CMV) disease. Attributing pathogenicity in burn patients remains difficult and controversial because data are sparse. In this work, we surveyed U.S. and German burn centers and evaluated them for awareness, perceptions, diagnosis, and treatment of CMV in patients with burn injury. A total of 58% German (G) and 21% U.S. centers responded. CMV infection incidence was 1:280 G and 1:870 U.S. A total of 41% G and 78% U.S. burn centers considered CMV to be of minor importance and 41% G and 13% U.S. centers considered CMV to be of significant importance. A total of 70% G and 97% U.S. centers performed no admission screening. When testing, 70% G and 19% U.S. centers used serology; 52% G and 25% U.S. centers used body fluid viral isolation; and 43% G and 6% U.S. centers used leukocyte CMV-DNA analysis. A total of 72% G and 48% U.S. centers distinguished infection from disease. Human CMV disease was diagnosed by CMV-DNA (82% G, 19% U.S.), direct virus isolation (43% G, 13% U.S.), or RNA detection (26% G, 0% U.S.). A total of 43% G and 19% U.S. would treat the established disease. Establishing consistent guidelines for screening, diagnosis, and treatment seems prudent in caring for the immunocompromised burn patient.

    Allergic rhinitis (AR) affects ~60 million people in the United States. This study evaluates awareness, attitudes, and behaviors of AR sufferers on the management of their condition. This U.S.-based survey evaluated 1600 adult AR sufferers to assess their perceptions of AR diagnosis, treatment preferences, and interactions with health care practitioners (HCPs). Two consumer groups of AR sufferers were assessed: users of over-the-counter (OTC) medications only (n = 1020) and users of prescription (Rx) ± OTC medications (n = 580). The Rx group included 451 intranasal steroid (INS) users. Eighty-two percent of respondents indicated that they require minimal to no HCP guidance to manage AR; 51% had not visited an HCP in the past 2 years. Eighty-six percent of respondents agreed that they can self-recognize AR symptoms, and 69% suspected allergies before diagnosis. On suspecting nasal allergies, 52% of sufferers purchased an OTC medication. Seventy-two percent of AR sufferers said they are likely to go to an HCP if symptoms persist after they tried multiple OTC options. Rx users perceived INSs to be more beneficial in treating AR and showed a high level of satisfaction (a score of 7.4 out of 10). Forty-eight percent of AR sufferers felt the need for more efficacious OTC medications to better manage their AR symptoms. This study indicated that AR sufferers perceive that they self-recognize AR symptoms and initiate their management with OTC options. The availability of OTC medications did not deter AR sufferers from visiting HCPs for advice when symptoms worsen. Nonetheless, more efficacious OTC options are still desired.

    Background and Objective Cervical cancer is one of the leading causes of morbidity and mortality amongst the gynecological cancers worldwide, especially in developing countries. It is imperative for at least health professionals in developing countries like Pakistan to have a sound knowledge about the disease. This study was carried out to assess the knowledge and awareness about cervical cancer and its prevention amongst health professionals in tertiary care hospitals in Karachi, Pakistan. Methods and Design A cross-sectional, interview based survey was conducted in June, 2009. Sample of 400 was divided between the three tertiary care centers. Convenience sampling was applied as no definitive data was available regarding the number of registered interns and nurses at each center. Results Of all the interviews conducted, 1.8% did not know cervical cancer as a disease. Only 23.3% of the respondents were aware that cervical cancer is the most common cause of gynecological cancers and 26% knew it is second in rank in mortality. Seventy-eight percent were aware that infection is the most common cause of cervical cancer, of these 62% said that virus is the cause and 61% of the respondents knew that the virus is Human Papilloma Virus (HPV). Majority recognized that it is sexually transmitted but only a minority (41%) knew that it can be detected by PCR. Only 26% of the study population was aware of one or more risk factors. Thirty seven percent recognized Pap smear as a screening test. In total only 37 out of 400 respondents were aware of the HPV vaccine. Conclusion This study serves to highlight that the majority of working health professionals are not adequately equipped with knowledge concerning cervical cancer. Continuing Medical Education program should be started at the hospital level along with conferences to spread knowledge about this disease. PMID:20548787

    In preparation for the introduction of human papillomavirus (HPV) vaccine, we investigated awareness and knowledge of HPV/HPV vaccine and potential acceptability to HPV vaccine among mothers with a teenage daughter in Weihai, Shandong, China. A cross-sectional survey was conducted in 2013 with a sample of 1850 mothers who had a daughter (aged 9–17 years) attending primary, junior and senior high schools. In the final sample (N = 1578, response rate 85.30%), awareness of HPV was reported by 305 (19.32%) mothers. Awareness varied significantly by daughter’s age (P<0.01), mother’s education level (P<0.01), mother’s occupation (P<0.01), household income (P<0.01) and residence type (P<0.01). Knowledge about HPV/HPV vaccine was poor with a mean total score of 3.56 (SD = 2.40) out of a possible score of 13. Mothers with a higher education level reported higher levels of knowledge (P = 0.02). Slightly more than one-fourth (26.49%) of mothers expressed their potential acceptability of HPV vaccine for their daughters. Acceptability increased along with increased daughters’ age (P<0.01), household income (P<0.01) and knowledge level (P<0.01). House wives and unemployed mothers had the highest acceptability (P<0.01). The most common reasons for not accepting HPV vaccination were “My daughter is too young to have risk of cervical cancer (30.95%)”, “The vaccine has not been widely used, and the decision will be made after it is widely used (24.91%)”, “Worry about the safety of the vaccine (22.85%)”. Awareness and knowledge of HPV/HPV vaccines are poor and HPV vaccine acceptability is low among these Chinese mothers. These results may help inform appropriate health education programs in this population. PMID:26766565

    Background Adverse pregnancy outcomes are undesirable events occurring during pregnancy and childbirth in mother or child, such as Preterm Low Birth Weight (PLBW) and preeclampsia. There is growing evidence that periodontitis may be a risk factor for preterm birth even after adjusting for known risk factors. Aim 1. To determine the knowledge and attitude of pregnant females about oral health. 2. To evaluate the oral hygiene practices of pregnant females. 3. To evaluate their awareness regarding effect of oral health on adverse pregnancy outcomes. 4. To assess whether there was any significant difference from their non pregnant counter parts. 5. To evaluate whether their awareness towards dental treatment had increased after conceiving. Materials and Methods 200 pregnant and 200 non-pregnant women filled up a validated questionnaire which comprised of questions on personal data, oral hygiene knowledge, attitude, oral hygiene practices and their awareness regarding the correlation of oral health to adverse pregnancy outcomes. Statistical Analysis Analyses were conducted using SPSS for Windows (version 15.0; SPSS Inc., Chicago, IL, USA). Results The results indicate no statistically significant differences in the variables assessed in both the groups, indicating that no further knowledge had been imparted to the women after they conceived. 96% women of both groups (p>0.05) had received no knowledge from the gynaecologist regarding the impact of oral health on pregnancy outcomes. 93.9% of pregnant women, and 89.5% of non pregnant women (p>0.05) did not go for routine dental check-ups. Only 3% of pregnant women were aware of oral health having a correlation with adverse pregnancy outcomes. Conclusion In our study, pregnancy did little to change future attitudes to dental care. To provide better oral health care, more knowledge needs to be made available to the pregnant women and the medical community. PMID:26674176

    Awareness about folic acid's effectiveness in reducing the risk of certain birth defects has increased among women in the United States; however, few Hispanic women are consuming enough folic acid daily. A 1998 survey conducted by the Gallup Organization for the National March of Dimes Birth Defects Foundation found that English-speaking Hispanic women had lower folic acid awareness (53% vs. 72%) and lower daily consumption (29% vs. 33%) than non-Hispanic White women. In 1999, the Centers for Disease Control and Prevention (CDC) conducted baseline surveys with Spanish-speaking Hispanic women in selected U.S. markets to measure folic acid awareness, knowledge, and consumption. A Spanish-language public service announcement (PSA) volunteer campaign and a paid Spanish-language media and community education campaign were conducted in 2000 and 2002, respectively. Comparisons of postcampaign surveys indicate that the paid media campaign was significantly more effective than the PSA campaign in increasing folic acid awareness, knowledge, and consumption among Spanish-speaking Hispanic women.

    Aim To assess awareness, knowledge, use, and attitudes toward evidence-based medicine (EBM) and The Cochrane Library (CL) among physicians from Zenica-Doboj Canton (ZDC), Bosnia and Herzegovina. Methods In this cross-sectional study, a self-administered anonymous questionnaire was sent by post to all state owned health institutions (2 hospitals and 11 Primary Health Care Institutions) in ZDC. The main outcome measures were physicians’ awareness of the Cochrane, awareness and use of CL, access to EBM databases, and access to internet at work. 358 of 559 physicians responded (63.69%). Results 23.18% of respondents stated they had access to EBM databases, but only 3.91% named the actual EBM databases they used. The question on the highest level of evidence in EBM was correctly answered by 35.7% respondents, 34.64% heard about Cochrane and 32.68% heard about CL. They obtained information about CL mostly on the internet and from colleagues, whereas the information about EBM was obtained mainly during continuous medical education. Conclusion Although the attitudes toward EBM are positive, there is a low awareness of EBM among physicians in ZDC. Open access to the CL should be used more. Educational interventions in popularizing EBM and Cochrane are needed to raise awareness both among students and practicing physicians, and finally among lay audience. PMID:26718762

    Australian nurses and midwives are expected to compile a professional development portfolio during their annual registration process. This study aimed to ascertain the current understanding, practice and future continuing professional development (CPD) needs of nurses and midwives employed in a regional area of Queensland, Australia. Perceived barriers and incentives for CPD were also measured. 289 public and private hospital nurses and midwives responded to the survey. Results showed that participants understood the new requirements, valued ongoing learning, preferred education to occur within work hours, and considered their workplaces as accepting of change. Approximately two-thirds of participants believed CPD should be shared between them and their employers. Barriers to undertaking CPD included understaffing, and the concern that CPD would interfere with time outside work. Organisational support positively influenced attitudes to CPD. This study highlights the importance of supportive management in encouraging their workforce to embrace ongoing learning and change. PMID:24099224

    Casemix is a tool that classifies patients according to their clinical similarity and the homogeneity of resources required. A descriptive study was conducted to assess the level of knowledge and attitude toward the casemix-based funding system among staff working in the Iranian Social Security Organization in Tehran. The survey showed that knowledge of casemix and diagnosis-related groups (DRG) was poor among the study group and any attempt to implement the casemix system--which about three-quarters of high-level staff had never heard of--would be likely to fail. This highlights the necessity for creating awareness of the casemix and DRG systems among the hospital staff before any action takes place. PMID:19166177

    The National Collaborating Centre for Methods and Tools (NCCMT) has developed several resources to support evidence-informed decision-making - the process of distilling and disseminating best available evidence from research, context, and experience - and knowledge translation, applying best evidence in practice. One such resource, the Registry of Methods and Tools, is a free online database of 195 methods and tools to support knowledge translation. Building on the identification of webinars as a strategy to improve the dissemination of information, NCCMT launched the Spotlight on Knowledge Translation Methods and Tools webinar series in 2012 to promote awareness and use of the Registry. To inform continued implementation of this webinar series, NCCMT conducted an evaluation of the series' potential to improve awareness and use of the methods/tools within the Registry, as well as identify areas for improvement and "what worked." For this evaluation, the following data were analyzed: electronic follow-up surveys administered immediately following each webinar; an additional electronic survey administered 6 months after two webinars; and Google Analytics for each webinar. As of November 2015, there have been 22 webinars conducted, reaching 2048 people in multiple sectors across Canada and around the world. Evaluation results indicate that the webinars increase awareness about the Registry and stimulate use of the methods/tools. Although webinar attendees were significantly less likely to have used the methods/tools 6 months after webinars, this may be attributed to the lack of an identified opportunity in their work to use the method/tool.

    ABSTRACT Aims: The aim of this study was to evaluate the knowledge and awareness among parents and general dental practitioners regarding rehabilitation with full coverage restoration in children following pulp therapy. Materials and methods: A multiple choice questionnaire was given to 1,000 parents and 400 general practitioners in this multicentric trial. The questionnaire assessed their beliefs, knowledge regarding care of primary teeth, assessment of treating children, and knowledge regarding importance of primary teeth. All the questionnaires were then compiled and statistically analyzed using Statistical Package for Social Sciences (SPSS) software. Results and discussion: 53% parents did not know the importance of primary teeth and 73% parents also thought that no treatment is possible for pulpally involved primary teeth. 20% parents believed that root canal treatment can be possible for children and only 10% knew about full coverage restorations. 40% of the general dentists felt that the best treatment in the case of primary necrotic teeth is extraction and only 13% knew about stainless steel crowns. 62% of general dental practitioners pointed out patients’ noninterest in providing crowns whereas 68% parents reported non-information by dentists. Conclusion: Both parents and general dental practitioners have incomplete and inadequate knowledge regarding full coverage restorations, and we need to improve the knowledge and dental awareness of the parents and the general dental practitioners.

    2013-01-01

    Background Awareness of infertility risk factors is an essential first step to safeguard future fertility. Whereas several studies have examined university students’ awareness of female fertility and related risk factors, the topic of male infertility has not been well examined. The objective of this study was to assess young men and women’s awareness, knowledge and perceptions of infertility, male and female infertility risk factors and assisted reproductive technologies (ART). Methods Semi-structured interviews were conducted in 2008 with a multi-ethnic sample of sixteen male and twenty-three female Ottawa university students, followed by qualitative data analysis to identify major themes. Interview topics included awareness of male and female infertility risk factors, infertility diagnosis/treatments and personal options in the event of future infertility. Results Participants were generally familiar with infertility as a biomedical health problem, could identify sex-specific risk factors but overestimated fertility of women in their thirties and ART success rates. Reproductive health knowledge gaps and confusion of the physiological life-stage of menopause with infertility were apparent. Most participants would pursue in vitro fertilization or international adoption in the event of personal infertility. Some participants wished to use a ‘natural’ approach and were concerned with potential side effects of ART-related medications. Conclusions The general awareness of infertility in young adults is promising and supports the potential uptake for health promotion of fertility preservation. This study underscores the continued need for comprehensive sexual and reproductive health education and promotion for adolescents and young adults. PMID:23962162

    Introduction Swine flu or Influenza A (H1N1) flu is the most recent of the pandemic disease that has affected the world’s population. We, as health care providers should feel responsible for reducing the transmission of influenza. Aim To conduct a systematic review of observational studies and to assess dental professionals’ knowledge and awareness regarding swine flu. Materials and Methods Relevant cross-sectional observational studies were included in the systematic review to assess the level of knowledge and awareness regarding swine flu among dental professionals. Three studies out of 28 were finally included in the present review after conducting both electronic and manual search of scientific databases like Pubmed, Medline, and EMBASE. No limitation in terms of publication date and language was considered. Potential biases were reported and appropriate data were extracted by the concerned investigators. Descriptive statistics, student t-test were used for analysis. Results Majority of the subjects (92.6%) had heard about swine flu, and 64.3% of them knew about the H1N1 virus in one of the study reports. More than 80% of subjects were aware regarding the availability of swine flu vaccine in one study reports as compared to another study in which only 31.5% had awareness. Majority of the subjects were of the opinion that frequent hand washing and use of sanitizer are one of the effective methods to prevent swine flu in all the three studies. Conclusion The results of the present review showed that some knowledge gaps existed among dental professionals regarding swine flu. Therefore, there is an urgent need for training and continuous education programs regarding infectious diseases. PMID:27790597

    AMP! (Arts-based, Multiple component, Peer-education) is an HIV intervention developed for high school adolescents. AMP! uses interactive theater-based scenarios developed by trained college undergraduates to deliver messages addressing HIV/STI prevention strategies, healthy relationships, and stigma reduction towards people living with HIV/AIDS. We used a pre-test/post-test, control group study design to simultaneously assess intervention effect on ninth grade students in an urban county in California (N = 159) and a suburban county in North Carolina (N = 317). In each location, the control group received standard health education curricula delivered by teachers; the intervention group received AMP! in addition to standard health education curricula. Structural equation modeling was used to determine intervention effects. The post-test sample was 46 % male, 90 % self-identified as heterosexual, 32 % reported receiving free or reduced lunch, and 49 % White. Structural models indicated that participation in AMP! predicted higher scores on HIV knowledge (p = 0.05), HIV awareness (p = 0.01), and HIV attitudes (p = 0.05) at the post-test. Latent means comparison analyses revealed post-test scores were significantly higher than pre-test scores on HIV knowledge (p = 0.001), HIV awareness (p = 0.001), and HIV attitudes (p = 0.001). Further analyses indicated that scores rose for both groups, but the post-test scores of intervention participants were significantly higher than controls (HIV knowledge (p = 0.01), HIV awareness (p = 0.01), and HIV attitudes (p = 0.05)). Thus, AMP!'s theater-based approach shows promise for addressing multiple adolescent risk factors and attitudes concerning HIV in school settings. PMID:27056632

    Personalized medicine, the ability to tailor diagnostic and treatment decisions for individual patients, is seen as the evolution of modern medicine. We characterize here the informatics resources available today or envisioned in the near future that can support clinical interpretation of genomic test results. We assume a clinical sequencing scenario (germline whole-exome sequencing) in which a clinical specialist, such as an endocrinologist, needs to tailor patient management decisions within his or her specialty (targeted findings) but relies on a genetic counselor to interpret off-target incidental findings. We characterize the genomic input data and list various types of knowledge bases that provide genomic knowledge for generating clinical decision support. We highlight the need for patient-level databases with detailed lifelong phenotype content in addition to genotype data and provide a list of recommendations for personalized medicine knowledge bases and databases. We conclude that no single knowledge base can currently support all aspects of personalized recommendations and that consolidation of several current resources into larger, more dynamic and collaborative knowledge bases may offer a future path forward.

    2015-01-01

    Febrile seizures are the most common paroxysmal episode during childhood, affecting up to one in 10 children. They are a major cause of emergency facility visits and a source of family distress and anxiety. Their etiology and pathophysiological pathways are being understood better over time; however, there is still more to learn. Genetic predisposition is thought to be a major contributor. Febrile seizures have been historically classified as benign; however, many emerging febrile seizure syndromes behave differently. The way in which human knowledge has evolved over the years in regard to febrile seizures has not been dealt with in depth in the current literature, up to our current knowledge. This review serves as a documentary of how scientists have explored febrile seizures, elaborating on the journey of knowledge as far as etiology, clinical features, approach, and treatment strategies are concerned. Although this review cannot cover all clinical aspects related to febrile seizures at the textbook level, we believe it can function as a quick summary of the past and current sources of knowledge for all varieties of febrile seizure types and syndromes.

    Context: There is a widespread ignorance among the public about the role of anesthesiologists and their responsibilities inside or outside the operating room both in developed and developing countries. Aims: The present study was conducted to assess the knowledge of literate and illiterate patient about the role of anesthesiologists and their concerns regarding anesthesiology. Setting and Design: This is a prospective study conducted in a preoperative anesthetic clinic of a large tertiary care hospital. The study consisted of a standard preanesthetic interview and questionnaire. Materials and Methods: After obtaining permission from the Ethics committee, patients in the age group 18–75 years of either sex undergoing elective surgery were included. The patients were divided into two groups on the basis of their education: Group A: included patient who are illiterate; Group B: included patients who are literate, completed a questionnaire, which was later evaluated. Statistical Analysis Used: Unpaired t test and correlation r test were used. Results: There was limited knowledge among both literates and illiterates regarding the perioperative role of anesthesiologists. They wanted to be fully explained about the anesthesiology technique and were keen to meet their anesthesiologist both before and after the surgery. Conclusion: To eliminate the ignorance among general public regarding the role of anesthesiologists, efforts must be made to educate and generate awareness among the population. PMID:25885722

  16. Epigenetic mechanisms in microbial members of the human microbiota: current knowledge and perspectives.

    The human microbiota and epigenetic processes have both been shown to play a crucial role in health and disease. However, there is extremely scarce information on epigenetic modulation of microbiota members except for a few pathogens. Mainly DNA adenine methylation has been described extensively in modulating the virulence of pathogenic bacteria in particular. It would thus appear likely that such mechanisms are widespread for most bacterial members of the microbiota. This review will present briefly the current knowledge on epigenetic processes in bacteria, give examples of known methylation processes in microbial members of the human microbiota and summarize the knowledge on regulation of host epigenetic processes by the human microbiota.

    When examining the healthcare industry, the need for continuing education in internal functions (i.e., HR management) has been documented. However, equally important to success in the healthcare industry are external functions such as marketing. In an expansion of research on internally focused functions, we report findings from an exploratory study designed to examine the perceptions of executives about managerial skill needs in the externally focused area of marketing. Specifically, we examine eight key tasks in marketing and ask executives to rate the level of knowledge required for each and then to assess current, or actual, levels of knowledge in the field. Findings suggest that pricing strategy, product strategy, and segmentation and targeting were the tasks that require the most knowledge for healthcare marketers, and that they do, in fact, perceive various gaps in all of the areas examined. Implications and suggestions for future research are provided.

    2011-01-01

    Q fever is an ubiquitous zoonosis caused by an resistant intracellular bacterium, Coxiella burnetii. In certain areas, Q fever can be a severe public health problem, and awareness of the disease must be promoted worldwide. Nevertheless, knowledge of Coxiella burnetii remains limited to this day. Its resistant (intracellular and environmental) and infectious properties have been poorly investigated. Further understanding of the interactions between the infected host and the bacteria is necessary. Domestic ruminants are considered as the main reservoir of bacteria. Infected animals shed highly infectious organisms in milk, feces, urine, vaginal mucus, and, very importantly, birth products. Inhalation is the main route of infection. Frequently asymptomatic in humans and animals, Q fever can cause acute or chronic infections. Financial consequences of infection can be dramatic at herd level. Vaccination with inactive whole-cell bacteria has been performed and proved effective in humans and animals. However, inactive whole-cell vaccines present several defects. Recombinant vaccines have been developed in experimental conditions and have great potential for the future. Q fever is a challenging disease for scientists as significant further investigations are necessary. Great research opportunities are available to reach a better understanding and thus a better prevention and control of the infection. PMID:22194752

    There are 32 individual specimens of Mantispidae (Insecta: Neuroptera) currently recorded from the fossil record, the oldest of which dates back to the Lower Jurassic. These include 19 described species (in 16 genera), 1 specimen described to genus level and 9 unnamed specimens The specimens have been assigned to the extant subfamilies Drepanicinae (4), Mantispinae (10), Symphrasinae (1), and the extinct subfamily Mesomantispinae (16), with one incertae sedis within Mantispidae. There are currently no known fossil representatives of the subfamily Calomantispinae. Mesithoninae has been removed from Mantispidae and placed back within Berothidae. The species Mesithone carnaria and M. monstruosa, however, are true mantispids and have been removed from Mesithone and placed within a new genus Karataumantispa gen. nov. in the subfamily Mesomantispinae. The current state of knowledge of the fossil record of Mantispidae is reviewed and a key to the genera of Mesomantispinae is provided. PMID:26249453

    Promoting environmental and health education is crucial to allow students to make conscious decisions based on scientific criteria. The study is based on the outcomes of an Educational Project implemented with Portuguese students and consisted of several activities, exploring pre-existent Scientific Gardens at the School, aiming to investigate the antibacterial, antitumor and anti-inflammatory properties of plant extracts, with posterior incorporation in soaps and creams. A logo and a webpage were also created. The effectiveness of the project was assessed via the application of a questionnaire (pre- and post-test) and observations of the participants in terms of engagement and interaction with all individuals involved in the project. This project increased the knowledge about autochthonous plants and the potential medical properties of the corresponding plant extracts and increased the awareness about the correct design of scientific experiments and the importance of the use of experimental models of disease. The students regarded their experiences as exciting and valuable and believed that the project helped to improve their understanding and increase their interest in these subjects and in science in general. This study emphasizes the importance of raising students’ awareness on the valorization of autochthonous plants and exploitation of their medicinal properties. PMID:25711362

    In this article, we advance the concept of "evolutionary awareness," a metacognitive framework that examines human thought and emotion from a naturalistic, evolutionary perspective. We begin by discussing the evolution and current functioning of the moral foundations on which our framework rests. Next, we discuss the possible applications of such an evolutionarily-informed ethical framework to several domains of human behavior, namely: sexual maturation, mate attraction, intrasexual competition, culture, and the separation between various academic disciplines. Finally, we discuss ways in which an evolutionary awareness can inform our cross-generational activities-which we refer to as "intergenerational extended phenotypes"-by helping us to construct a better future for ourselves, for other sentient beings, and for our environment.

    Monitoring the educational level of farmers and retailers on pesticide use would be useful to assess the appropriateness of information for reducing or/and avoiding the risks from pesticides in rural regions. The levels of knowledge and awareness of the dangers to the environment and human health were investigated by questionnaires for farmers (209) and retailers (20) in two rural regions (Qianyang County (S1) and Chencang County (S2)) of the Wei River catchment in China where the modes of farming and the state of erosion are very different. The results showed that farmers learned the use and dangers of pesticides mainly by oral communication (p<0.01). Protective measures were inadequate; 65% (S1) and 55% (S2) of farmers never used any protective measures during spraying (p<0.05). Washing hands (>70%) was the most common mode of personal hygiene, relative to wearing masks, showering, and changing clothes, but no significant differences were observed between the selected regions. Most pesticide wastes were dumped directly onto the land or into water, suggesting that educational measures should be taken to address the potential risks from the residues in the wastes. Over 85% of farmers (S1 and S2) claimed to use illegal pesticides, but the reasons for their use varied (p<0.01). Retailers were well-informed and highly conscious of their responsibility for the safe use of pesticides, especially in S2 (p<0.01). A canonical correspondence analysis indicated that educational level and age differed between the two regions and contributed greatly to the risks from pesticide use (p<0.01). Educational programmes targeted to age groups, proper disposal of pesticide waste, and sufficient supervision from authorities should consequently be considered for improving the levels of knowledge and awareness of the dangers of pesticides to human health and environmental pollution in the Wei River catchment, China.

    The principal aim of this study was to define and apply a procedure based on a structured questionnaire survey useful to analyze the people's environmental knowledge in order to select the areas and age groups with a low level of knowledge in a municipality (in Southern Italy) and, therefore, suggest a specific educational campaign for each. The detailed sampling procedure made it possible to carry out a meticulous statistical analysis of the results. The youngest and oldest people showed the lowest level of awareness for each district. A high level of education did not necessarily imply a high level of environmental awareness as well as a greater acceptance of MSW facilities. The satisfaction level of the recycling program was higher amongst the oldest age group. All the citizens in the several areas were unanimous in pointing out the presence of dirt in the street as the main shortcoming of the bring separate collection program. Only the youngest age group self-criticised, considering that they revealed a low level of participation to the separate collection program. While, the oldest people retaining them less influential, claimed that the citizens were not responsible for the failure of the separate collection program. The prevailing opinion of the sample was that people protested against the construction of waste facilities because they were not well-informed, with the most significant opinion of all the age subdivisions being that incineration is a hazardous treatment. The presence of criminal organizations was indicated as the main reason why the Campania Region suffers a serious solid waste emergency. While, the percentage of people pointing their finger at politicians increases with the average age of the respondents with there being a very strong correlation (r(2)=0.9903).

  13. Using Knowledge Translation to Craft “Sticky” Social Media Health Messages That Provoke Interest, Raise Awareness, Impart Knowledge, and Inspire Change

    2016-01-01

    Background In Australia, there is growing use of technology supported knowledge translation (KT) strategies such as social media and mobile apps in health promotion and in Indigenous health. However, little is known about how individuals use technologies and the evidence base for the impact of these health interventions on health behavior change is meager. Objective The objective of our study was to examine how Facebook is used to promote health messages to Indigenous people and discuss how KT can support planning and implementing health messages to ensure chosen strategies are fit for the purpose and achieve impact. Methods A desktop audit of health promotion campaigns on smoking prevention and cessation for Australian Indigenous people using Facebook was conducted. Results Our audit identified 13 out of 21 eligible campaigns that used Facebook. Facebook pages with the highest number of likes (more than 5000) were linked to a website and to other social media applications and demonstrated stickiness characteristics by posting frequently (triggers and unexpected), recruiting sporting or public personalities to promote campaigns (social currency and public), recruiting Indigenous people from the local region (stories and emotion), and sharing stories and experiences based on real-life events (credible and practical value). Conclusions KT planning may support campaigns to identify and select KT strategies that are best suited and well-aligned to the campaign’s goals, messages, and target audiences. KT planning can also help mitigate unforeseen and expected risks, reduce unwarranted costs and expenses, achieve goals, and limit the peer pressure of using strategies that may not be fit for purpose. One of the main challenges in using KT systems and processes involves coming to an adequate conceptualization of the KT process itself. PMID:27707685

    Neuromyelitis optica (NMO) is an autoimmune, demyelinating disorder of the central nervous system (CNS) with typical clinical manifestations of optic neuritis and acute transverse myelitis attacks. Previously believed to be a variant of multiple sclerosis (MS), it is now considered an independent disorder which needs to be differentiated from MS. The discovery of autoantibodies against aquaporin-4 (AQP4-IgGs) changed our understanding of NMO immunopathogenesis and revolutionized the diagnostic process. AQP4-IgG is currently regarded as a specific biomarker of NMO and NMO spectrum disorders (NMOsd) and a key factor in its pathogenesis. Nevertheless, AQP4-IgG seronegativity in 10%–25% of NMO patients suggests that there are several other factors involved in NMO immunopathogenesis, i.e., autoantibodies against aquaporin-1 (AQP1-Abs) and antibodies against myelin oligodendrocyte glycoprotein (MOG-IgGs). This manuscript reviews current knowledge about NMO immunopathogenesis, pointing out the controversial issues and showing potential directions for future research. Further efforts should be made to broaden our knowledge of NMO immunology which could have important implications for clinical practice, including the use of potential novel biomarkers to facilitate an early and accurate diagnosis, and modern treatment strategies improving long-term outcome of NMO patients.

  16. Current knowledge on the genetics of autism and propositions for future research.

    2016-01-01

    Autism spectrum disorders (ASD) are a heterogeneous group of neuropsychiatric disorders characterized by problems in social communication, as well as by the presence of restricted interests, stereotyped and repetitive behaviours. In the last 40years, genetic studies have provided crucial information on the causes of ASD and its diversity. In this article, I will first review the current knowledge on the genetics of ASD and then suggest three propositions to foster research in this field. Twin and familial studies estimated the heritability of ASD to be 50%. While most of the inherited part of ASD is captured by common variants, our current knowledge on the genetics of ASD comes almost exclusively from the identification of highly penetrant de novo mutations through candidate gene or whole exome/genome sequencing studies. Approximately 10% of patients with ASD, especially those with intellectual disability, are carriers of de novo copy-number (CNV) or single nucleotide variants (SNV) affecting clinically relevant genes for ASD. Given the function of these genes, it was hypothesized that abnormal synaptic plasticity and failure of neuronal/synaptic homeostasis could increase the risk of ASD. In addition to these discoveries, three propositions coming from institutions, researchers and/or communities of patients and families can be made to foster research on ASD: (i) to use more dimensional and quantitative data than diagnostic categories; (ii) to increase data sharing and research on genetic and brain diversity in human populations; (iii) to involve patients and relatives as participants for research. Hopefully, this knowledge will lead to a better diagnosis, care and integration of individuals with ASD.

    This study evaluated the effects of mobilizing community coalitions and implementing prevention intervention concerning public awareness, knowledge, and perception of the risks associated with club drug use by Taiwanese urban youth. A quasi-experimental design was used. Three communities in Taipei city were included in the present study. A total of 328 residents successfully participated in the baseline survey (April 2008), and 276 residents were successfully interviewed for the follow-up survey (September 2008). The generalized estimating equation (GEE) method was used. The percentage of the intervention respondents who reported having seen or heard antidrug messages increased significantly between the time of the baseline survey (63.7%) and the follow-up survey (77.4%), while the percentage of attendance at antidrug events increased from 23.1% to 38.7% during the same time interval. In addition, community knowledge and perception of the problem of club drug use by youth rose significantly between the baseline and the follow-up in the intervention communities. The study's limitations are noted. PMID:21619445

    Tardigrades are microscopic animals found worldwide in aquatic as well as terrestrial ecosystems. They belong to the invertebrate superclade Ecdysozoa, as do the two major invertebrate model organisms: Caenorhabditis elegans and Drosophila melanogaster. We present a brief description of the tardigrades and highlight species that are currently used as models for physiological and molecular investigations. Tardigrades are uniquely adapted to a range of environmental extremes. Cryptobiosis, currently referred to as a reversible ametabolic state induced by e.g. desiccation, is common especially among limno-terrestrial species. It has been shown that the entry and exit of cryptobiosis may involve synthesis of bioprotectants in the form of selective carbohydrates and proteins as well as high levels of antioxidant enzymes and other free radical scavengers. However, at present a general scheme of mechanisms explaining this phenomenon is lacking. Importantly, recent research has shown that tardigrades even in their active states may be extremely tolerant to environmental stress, handling extreme levels of ionizing radiation, large fluctuation in external salinity and avoiding freezing by supercooling to below -20 °C, presumably relying on efficient DNA repair mechanisms and osmoregulation. This review summarizes the current knowledge on adaptations found among tardigrades, and presents new data on tardigrade cell numbers and osmoregulation.

    Expert opinion was canvassed to identify crucial knowledge gaps in current understanding of climate change impacts on coral reef fishes. Scientists that had published three or more papers on the effects of climate and environmental factors on reef fishes were invited to submit five questions that, if addressed, would improve our understanding of climate change effects on coral reef fishes. Thirty-three scientists provided 155 questions, and 32 scientists scored these questions in terms of: (i) identifying a knowledge gap, (ii) achievability, (iii) applicability to a broad spectrum of species and reef habitats, and (iv) priority. Forty-two per cent of the questions related to habitat associations and community dynamics of fish, reflecting the established effects and immediate concern relating to climate-induced coral loss and habitat degradation. However, there were also questions on fish demographics, physiology, behaviour and management, all of which could be potentially affected by climate change. Irrespective of their individual expertise and background, scientists scored questions from different topics similarly, suggesting limited bias and recognition of a need for greater interdisciplinary and collaborative research. Presented here are the 53 highest-scoring unique questions. These questions should act as a guide for future research, providing a basis for better assessment and management of climate change impacts on coral reefs and associated fish communities.

    Cardiovascular and neuroendocrine reactivity to acute stress are important predictors of health outcomes in non-pregnant populations. Greater magnitude and duration of physiological responses have been associated with increased risk of hypertensive disorders and diabetes, greater susceptibility to infectious illnesses, suppression of cell-mediated immunity as well as risk for depression and anxiety disorders. Stress reactivity during pregnancy has unique implications for maternal health, birth outcomes, and fetal development. However, as compared to the larger literature, our understanding of the predictors and consequences of exaggerated stress reactivity in pregnancy is limited. This paper reviews the current state of this literature with an emphasis on gaps in knowledge and future directions. PMID:22800930

    Influenza viruses are a public health threat, as they are pathogenic, highly transmissible and prone to genetic changes. For decades vaccination strategies have been based on trivalent inactivated vaccines, which are regulated by specific guidelines. The progress in scientific knowledge and the lessons learned from the A(H1N1)2009 pandemic have highlighted further the need to improve current guidelines, including the immunogenicity criteria set by the CHMP in 1997, and to promote the discussion on the shortcomings encountered, e.g. the evaluation of vaccine efficacy in the paediatric and elderly populations, the measurement of the naivety of a population, the impact of prior immunity on subsequent vaccinations, and the technical issues with the serological assays for detection of immunity and immunogenicity. The authors attempted to summarise and tackle key gaps in the existing evidence concerning quality and efficacy of influenza vaccines, aiming at favouring a common understanding and a coordinated approach across stakeholders.

    Emergency responders need access to information but what counts as actionable information depends on their role, task, location, and other variables. For example, experts who have unique knowledge and experience and are called on to serve as scientific and teclmical responders, require correspondingly unique situation awareness in order to do their work. In our research-in-progress we leverage emerging and evolving web and digital library technologies to create personalized situation awareness tools that address the needs of these scientific and technical responders in real time, through focused information collection, extraction, integration, representation, and dissemination. We describe three personalized situation awareness tools in this paper: the Theme Awareness Tool (THEMAT), Social Awareness Tool (SAT), and Expertise Awareness Tool (EXPAT). The concepts and technologies we are developing in collaboration with experts apply to those who use the Web, in general, and offer an approach to the general issue of HCI design for emergencies.

    Currently, 17–19% of all new primary malignancies occur in survivors of cancer, causing substantial morbidity and mortality. Research has shown that cancer treatments are important contributors to second malignant neoplasm (SMN) risk. In this paper we summarise current knowledge with regard to treatment-related SMNs and provide recommendations for future research. We address the risks associated with radiotherapy and systemic treatments, modifying factors of treatment-related risks (genetic susceptibility, lifestyle) and the potential benefits of screening and interventions. Research priorities were identified during a workshop at the 2014 Cancer Survivorship Summit organised by the European Organisation for Research and Treatment of Cancer. Recently, both systemic cancer treatments and radiotherapy approaches have evolved rapidly, with the carcinogenic potential of new treatments being unknown. Also, little knowledge is available about modifying factors of treatment-associated risk, such as genetic variants and lifestyle. Therefore, large prospective studies with biobanking, high quality treatment data (radiation dose–volume, cumulative drug doses), and data on other cancer risk factors are needed. International collaboration will be essential to have adequate statistical power for such investigations. While screening for SMNs is included in several follow-up guidelines for cancer survivors, its effectiveness in this special population has not been demonstrated. Research into the pathogenesis, tumour characteristics and survival of SMNs is essential, as well as the development of interventions to reduce SMN-related morbidity and mortality. Prediction models for SMN risk are needed to inform initial treatment decisions, balancing chances of cure and SMNs and to identify high-risk subgroups of survivors eligible for screening.

    Most of the lentil growing countries face a certain set of abiotic and biotic stresses causing substantial reduction in crop growth, yield, and production. Until-to date, lentil breeders have used conventional plant breeding techniques of selection-recombination-selection cycle to develop improved cultivars.These techniques have been successful in mainstreaming some of the easy-to-manage monogenic traits. However, in case of complex quantitative traits, these conventional techniques are less precise. As most of the economic traits are complex, quantitative, and often influenced by environments and genotype–environment interaction, the genetic improvement of these traits becomes difficult. Genomics assisted breeding is relatively powerful and fast approach to develop high yielding varieties more suitable to adverse environmental conditions. New tools such as molecular markers and bioinformatics are expected to generate new knowledge and improve our understanding on the genetics of complex traits. In the past, the limited availability of genomic resources in lentil could not allow breeders to employ these tools in mainstream breeding program.The recent application of the next generation sequencing and genotyping by sequencing technologies has facilitated to speed up the lentil genome sequencing project and large discovery of genome-wide single nucleotide polymorphism (SNP) markers. Currently, several linkage maps have been developed in lentil through the use of expressed sequenced tag (EST) derived simple sequence repeat (SSR) and SNP markers.These maps have emerged as useful genomic resources to identify quantitative trait loci imparting tolerance to biotic and abiotic stresses in lentil. In this review, the current knowledge on available genomic resources and its application in lentil breeding program are discussed. PMID:25755659

    Exposure to heparin is associated with a high incidence of immunization against platelet factor 4 (PF4)/heparin complexes. A subgroup of immunized patients is at risk of developing heparin-induced thrombocytopenia (HIT), an immune mediated prothrombotic adverse drug effect. Transplant recipients are frequently exposed to heparin either due to the underlying end-stage disease, which leads to listing and transplantation or during the transplant procedure and the perioperative period. To review the current scientific knowledge on anti-heparin/PF4 antibodies and HIT in transplant recipients a systematic PubMed literature search on articles in English language was performed. The definition of HIT is inconsistent amongst the publications. Overall, six studies and 15 case reports have been published on HIT before or after heart, liver, kidney, and lung transplantation, respectively. The frequency of seroconversion for anti-PF4/heparin antibodies ranged between 1.9% and 57.9%. However, different methods to detect anti-PF4/heparin antibodies were applied. In none of the studies HIT-associated thromboembolic events or fatalities were observed. More importantly, in patients with a history of HIT, reexposure to heparin during transplantation was not associated with thrombotic complications. Taken together, the overall incidence of HIT after solid organ transplantation seems to be very low. However, according to the current knowledge, cardiac transplant recipients may have the highest risk to develop HIT. Different alternative suggestions for heparin-free anticoagulation have been reported for recipients with suspected HIT albeit no official recommendations on management have been published for this special collective so far.

    Occurrence of quadricuspid aortic valves has been reported in humans, in nine dogs and in a greater white-toothed shrew. Moreover, two cases of developing aortic valves with four anticipated leaflets have been described in Syrian hamster embryos. Currently, however, no case of quadricuspid aortic valve in adult hamsters has been recorded. The aim here is to present four adults of this rodent species, two of them with unequivocally quadricuspid aortic valves and the other two with quadricuspid-like aortic valves. The four anomalous aortic valves were detected among 4,190 Syrian hamsters examined in our laboratory, representing an incidence of 0.09%. None of the affected hamsters showed apparent signs of disease. The present findings are considered on the light of current empirical knowledge about the morphogenesis of quadricuspid and bicuspid aortic and pulmonary valves. Quadricuspid aortic valves result from the partition of one of the normal mesenchymal cushions which normally give rise to normal (tricuspid) valves, while quadricuspid-like valves might be the product of a combined mechanism of fusion and partition of the cushions at the onset of the valvulogenesis. The presence of aortic valves with four leaflets in ancient mammalian lineages such as insectivors and rodents suggest that quadricuspid aortic valves, although showing almost certainly a low incidence, may be widespread among the different groups of mammals, including domestic animals.

    The Middle East respiratory syndrome coronavirus (MERS-CoV) that causes a severe lower respiratory tract infection in humans is now considered a pandemic threat to the Gulf region. Since its discovery in 2012, MERS-CoV has reached 23 countries affecting about 1100 people, including a dozen children, and claiming over 400 lives. Compared to SARS (severe acute respiratory syndrome), MERS-CoV appears to kill more people (40% versus 10%), more quickly, and is especially more severe in those with pre-existing medical conditions. Most MERS-CoV cases (>85%) reported thus far have a history of residence in, or travel to the Middle East. The current epidemiology is characterised by slow and sustained transmission with occasional sparks. The dromedary camel is the intermediate host of MERS-CoV, but the transmission cycle is not fully understood. In this current review, we have briefly summarised the latest information on the epidemiology, clinical features, diagnosis, treatment and prevention of MERS-CoV especially highlighting the knowledge gaps in its transmission dynamics, diagnosis and preventive strategy.

    Subpopulation growth rates and the probability of decline at current harvest levels were determined for 13 subpopulations of polar bears (Ursus maritimus) that are within or shared with Canada based on mark-recapture estimates of population numbers and vital rates, and harvest statistics using population viability analyses (PVA). Aboriginal traditional ecological knowledge (TEK) on subpopulation trend agreed with the seven stable/increasing results and one of the declining results, but disagreed with PVA status of five other declining subpopulations. The decline in the Baffin Bay subpopulation appeared to be due to over-reporting of harvested numbers from outside Canada. The remaining four disputed subpopulations (Southern Beaufort Sea, Northern Beaufort Sea, Southern Hudson Bay, and Western Hudson Bay) were all incompletely mark-recapture (M-R) sampled, which may have biased their survival and subpopulation estimates. Three of the four incompletely sampled subpopulations were PVA identified as nonviable (i.e., declining even with zero harvest mortality). TEK disagreement was nonrandom with respect to M-R sampling protocols. Cluster analysis also grouped subpopulations with ambiguous demographic and harvest rate estimates separately from those with apparently reliable demographic estimates based on PVA probability of decline and unharvested subpopulation growth rate criteria. We suggest that the correspondence between TEK and scientific results can be used to improve the reliability of information on natural systems and thus improve resource management. Considering both TEK and scientific information, we suggest that the current status of Canadian polar bear subpopulations in 2013 was 12 stable/increasing and one declining (Kane Basin). We do not find support for the perspective that polar bears within or shared with Canada are currently in any sort of climate crisis.

    Game theoretical methods have been used for spectral awareness, space situational awareness (SSA), cyber situational awareness (CSA), and Intelligence, Surveillance, and Reconnaissance situation awareness (ISA). Each of these cases, awareness is supported by sensor estimation for assessment and the situation is determined from the actions of multiple players. Game theory assumes rational actors in a defined scenario; however, variations in social, cultural and behavioral factors include the dynamic nature of the context. In a dynamic data-driven application system (DDDAS), modeling must include both the measurements but also how models are used by different actors with different priorities. In this paper, we highlight the applications of game theory by reviewing the literature to determine the current state of the art and future needs. Future developments would include building towards knowledge awareness with information technology (e.g., data aggregation, access, indexing); multiscale analysis (e.g., space, time, and frequency), and software methods (e.g., architectures, cloud computing, protocols).

  16. Sea urchin overgrazing of seagrasses: A review of current knowledge on causes, consequences, and management

    Sea urchins are one of the most common seagrass macro-grazers in contemporary seagrass systems. Occasionally their grazing rates exceed seagrass growth rates, a phenomenon sometimes referred to as overgrazing. Because of a reported increasing frequency of overgrazing events, concomitant with loss of seagrass-associated ecosystem services, it has been suggested that overgrazing is one of the key threats to tropical and subtropical seagrasses. In light of this, we review the current knowledge on causes, consequences, and management of sea urchin overgrazing of seagrasses. Initially we argue that the definition of overgrazing must include scale and impairment of ecosystem services, since this is the de facto definition used in the literature, and will highlight the potential societal costs of seagrass overgrazing. A review of 16 identified cases suggests that urchin overgrazing is a global phenomenon, ranging from temperate to tropical coastal waters and involving at least 11 seagrass and 7 urchin species. Even though most overgrazing events seem to affect areas of <0.5 km 2, and recovery often occurs within a few years, overgrazing can have a range of large, long-term indirect effects such as loss of associated fauna and decreased sediment stabilization. A range of drivers behind overgrazing have been suggested, including bottom-up (nutrient enrichment), top-down (reduced predation control due to e.g. overfishing), "side-in" mechanisms (e.g. changes in water temperature) and natural population fluctuations. Based on recent studies, there seems to be fairly strong support for the top-down and bottom-up hypotheses. However, many potential drivers often co-occur and interact, especially in areas with high anthropogenic pressure, suggesting that multiple disturbances—by simultaneously reducing predation control, increasing urchin recruitment and reducing the resistance of seagrasses—could pave the way for overgrazing. In management, the most common response to

    2010-01-01

    Background Global Assessment of Functioning (GAF) is well known internationally and widely used for scoring the severity of illness in psychiatry. Problems with GAF show a need for its further development (for example validity and reliability problems). The aim of the present study was to identify gaps in current knowledge about properties of GAF that are of interest for further development. Properties of GAF are defined as characteristic traits or attributes that serve to define GAF (or may have a role to define a future updated GAF). Methods A thorough literature search was conducted. Results A number of gaps in knowledge about the properties of GAF were identified: for example, the current GAF has a continuous scale, but is a continuous or categorical scale better? Scoring is not performed by setting a mark directly on a visual scale, but could this improve scoring? Would new anchor points, including key words and examples, improve GAF (anchor points for symptoms, functioning, positive mental health, prognosis, improvement of generic properties, exclusion criteria for scoring in 10-point intervals, and anchor points at the endpoints of the scale)? Is a change in the number of anchor points and their distribution over the total scale important? Could better instructions for scoring within 10-point intervals improve scoring? Internationally, both single and dual scales for GAF are used, but what is the advantage of having separate symptom and functioning scales? Symptom (GAF-S) and functioning (GAF-F) scales should score different dimensions and still be correlated, but what is the best combination of definitions for GAF-S and GAF-F? For GAF with more than two scales there is limited empirical testing, but what is gained or lost by using more than two scales? Conclusions In the history of GAF, its basic properties have undergone limited changes. Problems with GAF may, in part, be due to lack of a research programme testing the effects of different changes in basic

    A review of the current state of knowledge on the effects of radiation on concrete in nuclear applications is presented. Emphasis is placed on the effects of radiation damage as reflected by changes in engineering properties of concrete in the evaluation of the long-term operation (LTO) and for Plant Life or Aging Management of nuclear power plants (NPPs) in Japan, Spain, and the United States. National issues and concerns are described for Japan and the US followed by a discussion of the fundamental understanding of the effects radiation on concrete. Specifically, the effects of temperature, moisture content, and irradiation onmore » ordinary Portland cement paste and the role of temperature and neutron energy spectra on radiation induced volumetric expansion (RIVE) of aggregate-forming minerals are described. This is followed by a discussion of the bounding conditions for extended operation, the significance of accelerated irradiation conditions, the role of temperature, creep, and how these issues are being incorporated into numerical and meso-scale models. From these insights on radiation damage, analyses of these effects on concrete structures are reviewed and the current status of work in Japan and the US are described. Also discussed is the recent formation of a new international scientific and technical organization, the International Committee on Irradiated Concrete (ICIC), to provide a forum for timely information exchanges among organizations pursuing the identification, quantification, and modeling of the effects of radiation on concrete in commercial nuclear applications. Lastly, the paper concludes with a discussion of research gaps including: 1) interpreting test-reactor data, 2) evaluating service-irradiated concrete for aging management and to inform radiation damage models with the Zorita NPP (Spain) serving as the first comprehensive test case, 3) irradiated-assisted alkali-silica reactions, and 4) RIVE under constrained conditions.« less

    The growing availability of innovative treatments for rare genetic diseases with a cardiac component-such as the mucopolysaccharidoses (MPSs)-has changed these syndromes from 'back of the textbook' curiosities of childhood to chronic, but rare, adult cardiac conditions that require both centres of expertise and knowledgeable subspecialists. The MPSs are inherited progressive lysosomal storage diseases, occurring in about 1:25 000 births and resulting from absence of functional hydrolases responsible for the degradation of glycosaminoglycans, naturally occurring complex sugars ubiquitous throughout the body. In the heart, accumulation of glycosaminoglycans occurs within the cardiac valves, the epicardial coronary arteries, the myocytes and cardiac interstitium and the walls of the great vessels. As a consequence, cardiac valve regurgitation and stenosis, diffuse coronary artery stenosis, myocardial dysfunction and aortic root dilation often occur. Haematopoietic cell transplantation and enzyme replacement therapy have changed the previously lethal natural history of the MPSs to one of survival well into adulthood. Despite this improved lifespan, the left-sided cardiac valves continue to show progressive functional involvement and cardiac valve replacement is not uncommon, especially in adults. The risk of any intervention is increased in these patients because of the systemic effects of the disease on the respiratory system and cervical cord. Our current understanding of other cardiac issues in adults with the MPSs, especially with the coronary circulation and myocardium, is meagre and more needs to be known to effectively care for this emerging population of adults. Incorporation of the MPSs, as well as other now-treatable rare diseases, into the educational curriculum of current and future adult subspecialists is an important next step. PMID:27102649

    Awareness is the knowledge about present and past group’s activities and it is a relevant issue for cooperative work. There are many devices that supply awareness information in synchronous collaborative editing systems. However, the current awareness devices have restrictions to both accomplish effective awareness and show the focus of attention identifying the exact place of the participants’ attention. This paper presents an awareness widget for synchronous collaborative editing systems called TeleEye that provides information about the localization of the participants’ attention during a collaborative session by means of eye tracking.

    The interest in effects of strontium (Sr) on bone has greatly increased in the last decade due to the development of the promising drug strontium ranelate. This drug is used for treating osteoporosis, a major bone disease affecting hundreds of millions of people worldwide, especially postmenopausal women. The novelty of strontium ranelate compared to other treatments for osteoporosis is its unique effect on bone: it simultaneously promotes bone formation by osteoblasts and inhibits bone resorption by osteoclasts. Besides affecting bone cells, treatment with strontium ranelate also has a direct effect on the mineralized bone matrix. Due to the chemical similarities between Sr and Ca, a topic that has long been of particular interest is the incorporation of Sr into bones replacing Ca from the mineral phase, which is composed by carbonated hydroxyapatite nanocrystals. Several groups have analyzed the mineral produced during treatment; however, most analysis were done with relatively large samples containing numerous nanocrystals, resulting thus on data that represents an average of many crystalline domains. The nanoscale analysis of the bone apatite crystals containing Sr has only been described in a few studies. In this study, we review the current knowledge on the effects of Sr on bone mineral and discuss the methodological approaches that have been used in the field. In particular, we focus on the great potential that advanced microscopy and microanalytical techniques may have on the detailed analysis of the nanostructure and composition of bone apatite nanocrystals produced during treatment with strontium ranelate.

    Among the many cetacean species that occupy Australian coastal waters, Australian humpback dolphins, Sousa sahulensis, are one of the most vulnerable to extirpation due to human activities. This review summarises the existing knowledge, presently occurring and planned research projects, and current conservation measures for humpback dolphins in Western Australia (WA). Rapid and wide-scale coastal development along the northern WA coastline has occurred despite a lack of baseline data for inshore dolphins and, therefore, without a precautionary approach to their conservation. The distribution, abundance, habitat use, and population structure of humpback dolphins remain poorly understood. Less than 1% of their inferred distribution has so far been studied to understand local population demography. The sparse data available suggest that WA humpback dolphins occur as localised populations in low numbers within a range of inshore habitats, including both clear and turbid coastal waters. Marine protected areas cover a third of their inferred distribution in WA, but the efficacy of these reserves in protecting local cetacean populations is unknown. There is a pressing need for coordination and collaboration among scientists, government agencies, industry bodies, Traditional Owners, and local community groups to fill in the gaps of information on humpback dolphins in WA. The recently developed strategies and sampling guidelines developed by state and federal governments should serve as a best practise standard for collection of data aimed at assessing the conservation status of humpback dolphins in WA and Australia.

    Saccharomyces cerevisiae is by far the most widely used yeast in oenology. However, during the last decade, several other yeasts species has been purposed for winemaking as they could positively impact wine quality. Some of these non-conventional yeasts (Torulaspora delbrueckii, Metschnikowia pulcherrima, Pichia kluyveri, Lachancea thermotolerans, etc.) are now proposed as starters culture for winemakers in mixed fermentation with S. cerevisiae, and several others are the subject of various studies (Hanseniaspora uvarum, Starmerella bacillaris, etc.). Along with their biotechnological use, the knowledge of these non-conventional yeasts greatly increased these last 10 years. The aim of this review is to describe the last updates and the current state-of-art of the genetics of non-conventional yeasts (including S. uvarum, T. delbrueckii, S. bacillaris, etc.). We describe how genomics and genetics tools provide new data into the population structure and biodiversity of non-conventional yeasts in winemaking environments. Future challenges will lie on the development of selection programs and/or genetic improvement of these non-conventional species. We discuss how genetics, genomics and the advances in next-generation sequencing will help the wine industry to develop the biotechnological use of non-conventional yeasts to improve the quality and differentiation of wines.

    Many metabolic pathways and cellular processes occurring in most sub-cellular compartments depend on the functioning of iron-sulfur (Fe-S) proteins, whose cofactors are assembled through dedicated protein machineries. Recent advances have been made in the knowledge of the functions of individual components through a combination of genetic, biochemical and structural approaches, primarily in prokaryotes and non-plant eukaryotes. Whereas most of the components of these machineries are conserved between kingdoms, their complexity is likely increased in plants owing to the presence of additional assembly proteins and to the existence of expanded families for several assembly proteins. This review focuses on the new actors discovered in the past few years, such as glutaredoxin, BOLA and NEET proteins as well as MIP18, MMS19, TAH18, DRE2 for the cytosolic machinery, which are integrated into a model for the plant Fe-S cluster biogenesis systems. It also discusses a few issues currently subjected to an intense debate such as the role of the mitochondrial frataxin and of glutaredoxins, the functional separation between scaffold, carrier and iron-delivery proteins and the crosstalk existing between different organelles.

    One of the side effects of each electrical device work is the electromagnetic field generated near its workplace. All organisms, including humans, are exposed daily to the influence of different types of this field, characterized by various physical parameters. Therefore, it is important to accurately determine the effects of an electromagnetic field on the physiological and pathological processes occurring in cells, tissues, and organs. Numerous epidemiological and experimental data suggest that the extremely low frequency magnetic field generated by electrical transmission lines and electrically powered devices and the high frequencies electromagnetic radiation emitted by electronic devices have a potentially negative impact on the circadian system. On the other hand, several studies have found no influence of these fields on chronobiological parameters. According to the current state of knowledge, some previously proposed hypotheses, including one concerning the key role of melatonin secretion disruption in pathogenesis of electromagnetic field induced diseases, need to be revised. This paper reviews the data on the effect of electric, magnetic, and electromagnetic fields on melatonin and cortisol rhythms—two major markers of the circadian system as well as on sleep. It also provides the basic information about the nature, classification, parameters, and sources of these fields. PMID:25136557

    Magnetic properties of soils have adverse effects on metal detectors, particularly hampering operations during clearance of landmines and unexploded ordnance. Although there is well established research in soil magnetism and modeling electromagnetic induction systems these have tended to exist in disparate disciplines. Hence, a workshop was organized to bring together researchers, academics, stakeholders and manufacturers to discuss key priorities for research and technology in a unique multidisciplinary environment. Key knowledge gaps identified include limited information on the spatial heterogeneity of soil magnetic properties in 2D and 3D, whether current models describing soil responses are appropriate for all soils and the need for compensation mechanisms in detectors to be improved. Several priorities were identified that would maximize future developments for multidisciplinary research in soil magnetism and detector technology. These include acquiring well constrained empirical data on soil electromagnetic properties and detector response over the frequency range of detectors; development of predictive models of soil magnetic properties; investigating variability of soil magnetic properties in two and three dimensions across a range of scales. Improved communication between disciplines is key to effective targeting and realization of research priorities. Possible platforms include a multidisciplinary pilot study at an appropriate site and the development of an online repository to assist dissemination of results and information.

  7. The rings of Saturn: State of current knowledge and some suggestions for future studies

    The state of our current knowledge of the properties of the ring system as a whole, and of the particles individually, is assessed. Attention is primarily devoted to recent results and possibilities for exploration of the ring system by a Saturn orbiter. In particular, the infrared and microwave properties of the ring system are discussed. The behavior of the ring brightness is not well understood in the critical transition spectral region from approximately 100 micrometers to approximately 1 cm. Also, the dynamical behavior of the ring system is discussed. Recent theoretical studies show that ongoing dynamical effects continually affect the ring structure in azimuth (possibly producing the A ring brightness asymmetry) and in the vertical direction. Orbital spacecraft-based studies of the rings will offer several unique advantages and impact important cosmogonical questions. Bistatic radar studies and millimeter-wavelength spectrometer/radiometry will give particle sizes and composition limits needed to resolve the question of the density of the rings, and provide important boundary conditions on the state of Saturn's protoplanetary nebula near the time of planetary formation.

  8. Defining Established and Emerging Microbial Risks in the Aquatic Environment: Current Knowledge, Implications, and Outlooks

    This timely review primarily addresses important but presently undefined microbial risks to public health and to the natural environment. It specifically focuses on current knowledge, future outlooks and offers some potential alleviation strategies that may reduce or eliminate the risk of problematic microbes in their viable but nonculturable (VBNC) state and Cryptosporidium oocysts in the aquatic environment. As emphasis is placed on water quality, particularly surrounding efficacy of decontamination at the wastewater treatment plant level, this review also touches upon other related emerging issues, namely, the fate and potential ecotoxicological impact of untreated antibiotics and other pharmaceutically active compounds in water. Deciphering best published data has elucidated gaps between science and policy that will help stakeholders work towards the European Union's Water Framework Directive (2000/60/EC), which provides an ambitious legislative framework for water quality improvements within its region and seeks to restore all water bodies to “good ecological status” by 2015. Future effective risk-based assessment and management, post definition of the plethora of dynamic inter-related factors governing the occurrence, persistence and/or control of these presently undefined hazards in water will also demand exploiting and harnessing tangential advances in allied disciplines such as mathematical and computer modeling that will permit efficient data generation and transparent reporting to be undertaken by well-balanced consortia of stakeholders.

    African swine fever (ASF) is a major threat to the pig industry in Europe. Since 2007, ASF outbreaks have been ongoing in the Caucasus, Eastern Europe and the Baltic countries, causing severe economic losses for many pig farmers and pork producers. In addition, the number of ASF cases in wild boar populations has dramatically increased over the past few years. Evidence supports direct contact with infectious domestic pigs and wild boars, and consumption of contaminated feed, as the main transmission routes of ASF virus (ASFV) to domestic pigs. However, significant knowledge gaps highlight the urgent need for research to investigate the dynamics of indirect transmission via the environment, the minimal infective doses for contaminated feed ingestion, the probability of effective contacts between infectious wild boars and domestic pigs, the potential for recovered animals to become carriers and a reservoir for transmission, the potential virus persistence within wild boar populations and the influence of human behaviour for the spread of ASFV. This will provide an improved scientific basis to optimise current interventions and develop new tools and strategies to reduce the risk of ASFV transmission to domestic pigs. PMID:26966305

    Understanding of the effects of wildland fire and fire management on aquatic and riparian ecosystems is an evolving field, with many questions still to be resolved. Limitations of current knowledge, and the certainty that fire management will continue, underscore the need to summarize available information. Integrating fire and fuels management with aquatic ecosystem conservation begins with recognizing that terrestrial and aquatic ecosystems are linked and dynamic, and that fire can play a critical role in maintaining aquatic ecological diversity. To protect aquatic ecosystems we argue that it will be important to: (1) accommodate fire-related and other ecological processes that maintain aquatic habitats and biodiversity, and not simply control fires or fuels; (2) prioritize projects according to risks and opportunities for fire control and the protection of aquatic ecosystems; and (3) develop new consistency in the management and regulatory process. Ultimately, all natural resource management is uncertain; the role of science is to apply experimental design and hypothesis testing to management applications that affect fire and aquatic ecosystems. Policy-makers and the public will benefit from an expanded appreciation of fire ecology that enables them to implement watershed management projects as experiments with hypothesized outcomes, adequate controls, and replication.

    Elevated atmospheric [CO2] (ca) will undoubtedly affect the metabolism of tropical forests worldwide; however, critical aspects of how tropical forests will respond remain largely unknown. Here we review the current state of knowledge about physiological and ecological responses, with the aim of providing a framework that can help to guide future experimental research. Modelling studies have indicated that elevated ca can potentially stimulate photosynthesis more in the tropics than at higher latitudes, because suppression of photorespiration by elevated ca increases with temperature. However, canopy leaves in tropical forests could also potentially reach a high temperature threshold under elevated ca that will moderate the rise in photosynthesis. Belowground responses, including fine root production, nutrient foraging, and soil organic matter processing, will be especially important to the integrated ecosystem response to elevated CO2. Water-use efficiency will increase as ca rises, potentially impacting upon soil moisture status and nutrient availability. Recruitment may be differentially altered for some functional groups, potentially decreasing ecosystem carbon storage. Whole-forest CO2 enrichment experiments are urgently needed to test predictions of tropical forest functioning under elevated ca. Smaller scale experiments in the understory and in gaps would also be informative, and could provide stepping stones toward stand-scale manipulations.

    Rich evidence has shown that cannabis products exert a broad gamut of effects on emotional regulation. The main psychoactive ingredient of hemp, Δ9-tetrahydrocannabinol (THC), and its synthetic cannabinoid analogs have been reported to either attenuate or exacerbate anxiety and fear-related behaviors in humans and experimental animals. The heterogeneity of cannabis-induced psychological outcomes reflects a complex network of molecular interactions between the key neurobiological substrates of anxiety and fear and the endogenous cannabinoid system, mainly consisting of the arachidonic acid derivatives anandamide and 2-arachidonoylglycerol (2-AG) and two receptors, respectively termed CB1 and CB2. The high degree of interindividual variability in the responses to cannabis is contributed by a wide spectrum of factors, including genetic and environmental determinants, as well as differences in the relative concentrations of THC and other alkaloids (such as cannabidiol) within the plant itself. The present article reviews the currently available knowledge on the herbal, synthetic and endogenous cannabinoids with respect to the modulation of anxiety responses, and highlights the challenges that should be overcome to harness the therapeutic potential of some of these compounds, all the while limiting the side effects associated with cannabis consumption.

    Among the many cetacean species that occupy Australian coastal waters, Australian humpback dolphins, Sousa sahulensis, are one of the most vulnerable to extirpation due to human activities. This review summarises the existing knowledge, presently occurring and planned research projects, and current conservation measures for humpback dolphins in Western Australia (WA). Rapid and wide-scale coastal development along the northern WA coastline has occurred despite a lack of baseline data for inshore dolphins and, therefore, without a precautionary approach to their conservation. The distribution, abundance, habitat use, and population structure of humpback dolphins remain poorly understood. Less than 1% of their inferred distribution has so far been studied to understand local population demography. The sparse data available suggest that WA humpback dolphins occur as localised populations in low numbers within a range of inshore habitats, including both clear and turbid coastal waters. Marine protected areas cover a third of their inferred distribution in WA, but the efficacy of these reserves in protecting local cetacean populations is unknown. There is a pressing need for coordination and collaboration among scientists, government agencies, industry bodies, Traditional Owners, and local community groups to fill in the gaps of information on humpback dolphins in WA. The recently developed strategies and sampling guidelines developed by state and federal governments should serve as a best practise standard for collection of data aimed at assessing the conservation status of humpback dolphins in WA and Australia.

    The interest in effects of strontium (Sr) on bone has greatly increased in the last decade due to the development of the promising drug strontium ranelate. This drug is used for treating osteoporosis, a major bone disease affecting hundreds of millions of people worldwide, especially postmenopausal women. The novelty of strontium ranelate compared to other treatments for osteoporosis is its unique effect on bone: it simultaneously promotes bone formation by osteoblasts and inhibits bone resorption by osteoclasts. Besides affecting bone cells, treatment with strontium ranelate also has a direct effect on the mineralized bone matrix. Due to the chemical similarities between Sr and Ca, a topic that has long been of particular interest is the incorporation of Sr into bones replacing Ca from the mineral phase, which is composed by carbonated hydroxyapatite nanocrystals. Several groups have analyzed the mineral produced during treatment; however, most analysis were done with relatively large samples containing numerous nanocrystals, resulting thus on data that represents an average of many crystalline domains. The nanoscale analysis of the bone apatite crystals containing Sr has only been described in a few studies. In this study, we review the current knowledge on the effects of Sr on bone mineral and discuss the methodological approaches that have been used in the field. In particular, we focus on the great potential that advanced microscopy and microanalytical techniques may have on the detailed analysis of the nanostructure and composition of bone apatite nanocrystals produced during treatment with strontium ranelate.

    ABSTRACT The aims of this study were to describe awareness and knowledge of HIV/AIDS among Bangladeshi married women in rural areas and to examine associations between exposure to mass media and their awareness and comprehensive knowledge of HIV/AIDS where mass media has been suggested to be vital sources of information. From the original dataset of the sixth Bangladesh Demographic Health Survey in 2011, the data of 11,570 rural married women aged 15–49 years old were extracted. Logistic regression analyses were performed to estimate odds ratios (ORs) and 95% confidence intervals (CIs). We found that approximately two-thirds of women (63.0%) aged 15–49 years had heard about HIV/AIDS. Exposure to each type of media was significantly associated with awareness of HIV/AIDS. Comparing to those who were not exposed to each of the investigated media, the adjusted ORs of comprehensive knowledge of HIV/AIDS were significantly high for those exposed to newspapers/magazines less than once a week (1.34, 95% CI 1.09–1.65), newspapers/ magazines at least once a week (1.44, 95% CI 1.07–1.94), television at least once a week (1.41, 95% CI 1.18–1.68). It was suggested that television can be utilized to increase awareness and comprehensive knowledge of HIV/AIDS through effective programs. Although the level of exposure was still low, significant associations between exposure to newspapers/magazines and comprehensive knowledge of HIV/AIDS suggested potential of written messages to promote knowledge of HIV/AIDS.

    2014-01-01

    In 2012, world mollusk production in aquaculture reached a volume of 15,171,000 tons, representing 23% of total aquaculture production and positioning mollusks as the second most important category of aquaculture products (fishes are the first). Clams and oysters are the mollusk species with the highest production levels, followed in descending order by mussels, scallops, and abalones. In view of the increasing importance attached to genetic information on aquaculture, which can help with good maintenance and thus the sustainability of production, the present work offers a review of the state of knowledge on genetic and genomic information about mollusks produced in aquaculture. The analysis was applied to mollusks which are of importance for aquaculture, with emphasis on the 5 species with the highest production levels. According to FAO, these are: Japanese clam Ruditapes philippinarum; Pacific oyster Crassostrea gigas; Chilean mussel Mytilus chilensis; Blood clam Anadara granosa and Chinese clam Sinonovacula constricta. To date, the genomes of 5 species of mollusks have been sequenced, only one of which, Crassostrea gigas, coincides with the species with the greatest production in aquaculture. Another important species whose genome has been sequenced is Mytilus galloprovincialis, which is the second most important mussel in aquaculture production, after M. chilensis. Few genetic improvement programs have been reported in comparison with the number reported in fish species. The most commonly investigated species are oysters, with at least 5 genetic improvement programs reported, followed by abalones with 2 programs and mussels with one. The results of this work will establish the current situation with respect to the genetics of mollusks which are of importance for aquaculture production, in order to assist future decisions to ensure the sustainability of these resources.

    Dental caries is the most prevalent and costly oral infectious disease worldwide. Virulent biofilms firmly attached to tooth surfaces are prime biological factors associated with this disease. The formation of an exopolysaccharide-rich biofilm matrix, acidification of the milieu and persistent low pH at the tooth-biofilm interface are major controlling virulence factors that modulate dental caries pathogenesis. Each one offers a selective therapeutic target for prevention. Although fluoride, delivered in various modalities, remains the mainstay for the prevention of caries, additional approaches are required to enhance its effectiveness. Available antiplaque approaches are based on the use of broad-spectrum microbicidal agents, e.g. chlorhexidine. Natural products offer a rich source of structurally diverse substances with a wide range of biological activities, which could be useful for the development of alternative or adjunctive anticaries therapies. However, it is a challenging approach owing to complex chemistry and isolation procedures to derive active compounds from natural products. Furthermore, most of the studies have been focused on the general inhibitory effects on glucan synthesis as well as on bacterial metabolism and growth, often employing methods that do not address the pathophysiological aspects of the disease (e.g. bacteria in biofilms) and the length of exposure/retention in the mouth. Thus, the true value of natural products in caries prevention and/or their exact mechanisms of action remain largely unknown. Nevertheless, natural substances potentially active against virulent properties of cariogenic organisms have been identified. This review focuses on gaps in the current knowledge and presents a model for investigating the use of natural products in anticaries chemotherapy. PMID:21576957

    The release of harmful chemicals in the Asian environment has recently increased dramatically due to rising industrial and agricultural activities. About 60% of the global human population is currently living on the Asian continent and may thus be exposed to a large range of different chemicals. Different classes of organohalogen chemicals have indeed been reported in various environmental compartments from Asia including humans and wildlife, but this issue has received less attention in birds. In this article, we reviewed the available literature on levels of legacy persistent organic pollutants (POPs) and various flame retardants (FRs) in Asian avifauna to analyze the existing pool of knowledge as well as to identify the gaps that should be addressed in future research. Furthermore, we discussed the variation in levels of organohalogens based on differences in regions, trophic level, dietary sources and migratory behaviors of species including distribution patterns in different tissues of birds. Although the mass of published literature is very low and even absent in many important regions of Asia, we deduced from the reported studies that levels of almost all classes of organohalogens (OHCs) including FRs were highest in East Asian countries such as Japan, China and South Korea, except for HCHs that were found at maximum levels in birds of South India. Concentrations (ng/g LW) of different OHCs in Asian birds ranged between

  11. Mycobacterium bovis infection in the lion (Panthera leo): Current knowledge, conundrums and research challenges.

    PubMed

    2015-06-12

    Mycobacterium bovis has global public-health and socio-economic significance and can infect a wide range of species including the lion (Panthera leo) resulting in tuberculosis. Lions are classified as vulnerable under the IUCN Red List of Threatened Species and have experienced a 30% population decline in the past two decades. However, no attempt has been made to collate and critically evaluate the available knowledge of M. bovis infections in lions and potential effects on population. In this review we set out to redress this. Arguments suggesting that ingestion of infected prey animals are the main route of infection for lions have not been scientifically proven and research is needed into other possible sources and routes of infection. The paucity of knowledge on host susceptibility, transmission directions and therefore host status, manifestation of pathology, and epidemiology of the disease in lions also needs to be addressed. Advances have been made in diagnosing the presence of M. bovis in lions. However, these diagnostic tests are unable to differentiate between exposure, presence of infection, or stage of disease. Furthermore, there are contradictory reports on the effects of M. bovis on lion populations with more data needed on disease dynamics versus the lion population's reproductive dynamics. Knowledge on disease effects on the lion reproduction and how additional stressors such as drought or co-morbidities may interact with tuberculosis is also lacking. Filling these knowledge gaps will contribute to the understanding of mycobacterial infections and disease in captive and wild lions and assist in lion conservation endeavours.

    This study used a Chinese-language version of the Index of Science Reading Awareness to explore the science reading metacognition and comprehension of Taiwanese students. Structural equation modelling results confirmed the underlying model comprised three clusters of metacognitive knowledge: beliefs and confidence in science reading, knowledge of structure of science text, and knowledge of science reading strategies. The main contribution of the current research was to provide evidence about the relationship between metacognitive awareness and comprehension of science text. In addition, data comparisons to Canadian (British Columbia) benchmarks from the original development revealed that metacognitive awareness of science reading deteriorated from elementary to middle school in both countries, and there were no significant differences of metacognitive awareness of science reading between Canadian and Taiwanese students. Instructional suggestions for raising students' metacognitive awareness on science reading were discussed.

    2015-04-01

    Introduction The NER 300 programme, managed by the European Commission is one of the largest funding programmes for innovative low-carbon energy demonstration projects. NER 300 is so called because it is funded from the sale of 300 million emission allowances from the new entrants' reserve (NER) set up for the third phase of the EU emissions trading system (ETS). The programme aims to successfully demonstrate environmentally safe carbon capture and storage (CCS) and innovative renewable energy (RES) technologies on a commercial scale with a view to scaling up production of low-carbon technologies in the EU. Consequently, it supports a wide range of CCS and RES technologies (bioenergy, concentrated solar power, photovoltaics, geothermal, wind, ocean, hydropower, and smart grids). Funded projects and the role of geothermal projects for the programme In total, about EUR 2.1 billion have been awarded to 39 projects through the programme's 2 calls for proposals (the first awarded in December 2012, the second in July 2014). The programme has awarded around 70 mEUR funding to 3 geothermal projects in Hungary, Croatia and France (see Annex). The Hungarian geothermal project awarded funding under the first call will enter into operation at the end of 2015 and the rest are expected to start in 2016 (HR) and in 2018 (FR), respectively. Knowledge Sharing Knowledge sharing requirements are built into the legal basis of the programme as a critical tool to lower risks in bridging the transition to large-scale production of innovative renewable energy and CCS deployment. Projects have to submit annually to the European Commission relevant knowledge gained during that year in the implementation of their project. The relevant knowledge is aggregated and disseminated by the European Commission to industry, research, government, NGO and other interest groups and associations in order to provide a better understanding of the practical challenges that arise in the important step of

    2015-06-12

    Mycobacterium bovis has global public-health and socio-economic significance and can infect a wide range of species including the lion (Panthera leo) resulting in tuberculosis. Lions are classified as vulnerable under the IUCN Red List of Threatened Species and have experienced a 30% population decline in the past two decades. However, no attempt has been made to collate and critically evaluate the available knowledge of M. bovis infections in lions and potential effects on population. In this review we set out to redress this. Arguments suggesting that ingestion of infected prey animals are the main route of infection for lions have not been scientifically proven and research is needed into other possible sources and routes of infection. The paucity of knowledge on host susceptibility, transmission directions and therefore host status, manifestation of pathology, and epidemiology of the disease in lions also needs to be addressed. Advances have been made in diagnosing the presence of M. bovis in lions. However, these diagnostic tests are unable to differentiate between exposure, presence of infection, or stage of disease. Furthermore, there are contradictory reports on the effects of M. bovis on lion populations with more data needed on disease dynamics versus the lion population's reproductive dynamics. Knowledge on disease effects on the lion reproduction and how additional stressors such as drought or co-morbidities may interact with tuberculosis is also lacking. Filling these knowledge gaps will contribute to the understanding of mycobacterial infections and disease in captive and wild lions and assist in lion conservation endeavours. PMID:25891424

Field studies had also indented to estimate and map the impacts of fire in soil properties. Contrary to remote sensing studies, the mapping of fire effects on ash and soil properties in the field is specially carried out at small scale (e.g. slope or plot). The small scale resolution studies are important because identify small patterns that are normally ignored by remote sensing studies, but fundamental to understand the post-fire evolution of the burned areas. One of the important aspects of the small scale studies of fire effect on ash and soil properties is the great spatial variability, showing that the impact of fire is extremely heterogeneous in space and time (Outeiro et al., 2008; Pereira et al. in press). The small scale mapping of fire effects on soil properties normally is carried out using Geostatistical methods or using deterministic interpolation methods (Robichaud and Miller, 1999; Pereira et al., 2013). Several reports were published on the spatial distribution and mapping of ash and duff thickness (Robichaud and Miller, 1999; Pereira et al., 2013; Pereira et al. in press), fire severity (Pereira et al., 2014), ash chemical characteristics as total nitrogen (Pereira et al., 2010a), and ash extractable elements (Pereira et al., 2010b). Also, previous works mapped fire effects on soil temperature (Gimeno-Garcia et al., 2004), soil hydrophobicity (Woods et al., 2007), total nitrogen (Hirobe et al., 2003), phosphorous (Rodriguez et al., 2009) and major cations (Outeiro et al., 2008). It is important to integrate remote sensing and field based works of fire effects on ash and soil properties in order to have a better validation of the models predicted. The aim of this work is present the current knowledge about mapping fire effects in ash and soil properties at diverse

    Atopic eczema is a chronic skin condition affecting between 5% and 20% of children aged up to 11 years at one time or other. Research suggests that prevalence is increasing and various environmental factors have been implicated in the aetiology. While often seen to be a minor problem, research suggests that it can cause considerable disruption to the lives of children and their carers and involves significant cost for the family and health care systems. The current consensus is that the majority of cases of atopic eczema are most appropriately managed within primary care. However, management of the condition is problematic because diagnosis is often difficult. Consultations tend to focus on the physical aspects of the problems neglecting the psychosocial, while treatment remains mainly palliative and can be as diverse as the condition itself. More appropriate and effective primary care management and support for children with atopic eczema and their carers will only be developed if health professionals become more aware of the social context of the disease and the impact on the lives of those affected. Public health responses focusing on primary prevention are also needed. This paper reviews a diverse literature on the epidemiology of the condition, the way in which it affects the lives of children and their carers and the factors that shape their help seeking decisions. The aim is to contribute to a more substantial knowledge base for public health and primary care developments and to point to areas for future research

    This study aims to explore in depth the needs, current knowledge, and attitudes of all ranks of old age home staff. A large-scale qualitative study with 13 semistructured focus groups was conducted in Hong Kong. Key themes were extracted by framework analysis. Three major themes were extracted, including role as a service provider, current knowledge, and attitude toward palliative care. There was a marked difference in familiarity with the concept of ''palliative care'' between different groups of staff, yet both shared the motivation for enhancement. The biggest concerns for the staff were elderly residents' readiness to accept palliative care, manpower, and resources. Care staff, regardless of rank, seemed to welcome and be ready to adopt a palliative care approach in caring for old age home residents, though not without worries and concerns. PMID:19959840

    Maternal diabetes constitutes an unfavorable environment for fetal-placental and embryonic development. It is has important repercussion in modern obstetrics, since it is associated to an increased risk of neonatal and maternal morbidity, and it still is a significant medical challenge. The increased occurrence of diabetes worldwide, the increase in diabetes type 2 in women at reproductive age and the crossed generation of intrauterine programming for diabetes type 2 are the bases for the growing interest in utilization of diabetic experimental samples, with the aim to acquire knowledge about the mechanisms that induce development alterations in gestational diabetes. Several studies have shown the benefits of diabetes prevention, with interventions in lifestyle, metabolic improvement and control of cardiovascular risk factors to substantially prevent the complications of this devastating disease. Despite these findings, the recent revolution in the scientific knowledge, and the infinite number of new therapies for diabetes, there is still a large gap between what was learned through research and what is really done in public, clinical and community health. The negative economic impact of this complacency in people, families, and national economies is alarming. It is expected that translational research in the binomial diabetes and pregnancy are implemented in centers of excellence, in both basic and applied research, and complemented by multicenter clinical studies, conducted in a pragmatic way to increase the level of scientific evidence with more reliable diagnostic and propaedeutic resources.

    2013-02-01

    Although numerous studies have addressed the relationship between intrapartum neuraxial analgesia, particularly epidural fentanyl, and breastfeeding, substantial study design limitations have precluded the current literature from furnishing strong, clinically significant conclusions. Lack of randomized controlled trials, nonstandardization of breastfeeding evaluations across studies, and failure to control for confounding variables all pose significant problems. Further research is needed to elucidate the specific relationship between neuraxial opioids and breastfeeding and, if there are significant associations, whether these drugs act directly on neonatal brain tissue to attenuate exhibition of breastfeeding behaviors. In this review, I will detail the deficiencies of the current literature and make recommendations for future research. PMID:23302971

    One of the most dynamic events in public health is being mediated by the global spread of the invasive mosquito Aedes albopictus. Its rapid expansion and vectorial capacity for various arboviruses affect an increasingly larger proportion of the world population. Responses to the challenges of controlling this vector are expected to be enhanced by an increased knowledge of its biology, ecology, and vector competence. Details of population genetics and structure will allow following, and possibly predicting, the geographical and temporal dynamics of its expansion, and will inform the practical operations of control programs. Experts are coming together now to describe the history, characterize the present circumstances, and collaborate on future efforts to understand and mitigate this emerging public health threat.

    Mental illness is a growing, and largely unaddressed, problem for the population and for emergency department (ED) patients in particular. Extensive literature outlines sex and gender differences in mental illness’ epidemiology and risk and protective factors. Few studies, however, examined sex and gender differences in screening, diagnosis, and management of mental illness in the ED setting. Our consensus group used the nominal group technique to outline major gaps in knowledge and research priorities for these areas, including the influence of violence and other risk factors on the course of mental illness for ED patients. Our consensus group urges the pursuit of this research in general, and conscious use of a gender lens when conducting, analyzing, and authoring future ED-based investigations of mental illness.

Although there are some organs such as skin, gills, and gut are directly associated with the mucosal immunity of fish species, this mini review emphasizes the general knowledge on the role and production figures of skin mucus and factors affecting the secretion of skin mucus of fish species. As the skin mucus of fish species is the first defense line for protection against invading microorganisms such as pathogens (bacteria, virus), parasites, etc., the information for understanding the roles of the skin mucus is very important. Furthermore, the information in the review will shed light on the development of high quality aquafeeds for the sustainable aquaculture field as well. PMID:26779184

    Pancreatic cystic lesions are being detected with increasing frequency, largely due to advances in cross-sectional imaging. The most common neoplasms include serous cystadenomas, mucinous cystic neoplasms, intraductal papillary mucinous neoplasms, solid pseudopapillary neoplasms, and cystic pancreatic endocrine neoplasms. Computed tomography (CT), magnetic resonance imaging (MRI), and endoscopic ultrasound (EUS) are currently used as imaging modalities. EUS-guided fine needle aspiration has proved to be a useful diagnostic tool, and enables an assessment of tumor markers, cytology, chemistries, and DNA analysis. Here, we review the current literature on pancreatic cystic neoplasms, including classification, diagnosis, treatment, and recommendations for surveillance. Data for this manuscript was acquired via searching the literature from inception to December 2014 on PubMed and Ovid MEDLINE. PMID:25821410

    Shoulder pain is one of the most common musculoskeletal pathologies. Treatment by ESWT (extracorporeal shockwave therapy) has emerged as an alternative when conservative treatment fails in rotator cuff calcific tendinopathy, prior to invasive procedures. The clinical efficacy of ESWT in non-calcific tendinopathy remains controversial. The good results in the treatment of rotator cuff calcifications, have led to indications of ESWT being expanded to other shoulder pathologies. We review the current state of indications and evidence based practice.

    In the early 1990s, the equine hindgut microbial ecosystem looked like a "black box." Its vital role in hydrolyzing and fermenting fiber, thus providing energy to the host, was recognized. Although there was a critical lack of information on the hindgut microbes, their role in preventing intestinal diseases was suggested. Traditionally, the microbes of the horse hindgut were studied using culture-dependent techniques. More recently, culture-independent methods have been used and provided further insight. This review presents the history and updated knowledge regarding the microbes that live inside the different intestinal ecosystems and which collective genomes compose the hindgut microbiome. In the first section, the quantification and diversity are described for each microbial community as well as the implication of plant fiber degradation and their crucial role for an herbivore host. The microbial communities are presented in chronological order of discovery: due to their large size, protozoa were brought to light as early as 1843 in the horse cecum; in 1897, bacteria were described in the horse intestine; as early as 1910, monoflagellated eukaryotic organisms resembling protozoa were observed in the horse cecum; since then, they have been identified to be zoospores of anaerobic fungi; in 1970, bacteriophage-like particles were recognized in the cecum and colon of pony and horse; and finally, in 1996, archaea were identified in the horse cecum. The second section discusses the variations that can occur between digestive segments or between individuals. The representativeness of the fecal microbiota to the hindgut one is debated, especially as the majority of recent studies conducted on the horse hindgut are in fact focused on the feces, rather than the cecum or colon. Also, the representation of microbiota between individuals is questioned. It has long been suggested in the literature that some ponies or horses that were more susceptible to intestinal diseases

    2006-01-01

    The complement activation system, a key component of the innate immune system, protects the host from microorganisms such as bacteria, and other foreign threats including abnormal cells. However, it is also double-edged in that it can have negative effects in the host; excessive complement activation damages the host and can even kill in anaphylactic shock and septic shock. Regulation of the complement system is a useful strategy to control inflammatory diseases, including inflammatory arthritis. Rheumatoid arthritis is a common inflammatory disease worldwide. Many medicines are developed to control inflammation, including recently developed biological response modifiers such as anti-TNF and IL-6 agents. Nevertheless, in some patients disease remains difficult to control because of complications, side effects and tolerance of medicines. In inflammatory arthritis, including rheumatoid arthritis, there is abundant evidence implicating complement activation in humans and animal models. Therefore, anti-complement agents might be beneficial as part of clinical treatment. However, at present, there are still no applicable agents for therapeutic regulation of excessive complement activation in chronic disease. Novel agents in development might be useful as a strategy to control complement activation. Here I describe recent knowledge of the complement system in inflammatory arthritis, the recent developments in anti-complement agents and their considerable potential for the future.

    Pigs have been associated with several episodes of influenza outbreaks in the past and are considered to play a significant role in the ecology of influenza virus. The recent 2009 pandemic influenza A/H1N1 virus originated from swine and not only did it cause widespread infection in humans, but was also transmitted back to swine in Asia, Europe and America. What may be the prevailing situation in Africa, particularly in sub-Saharan Africa, with respect to the circulation of classical swine or pandemic influenza? The ecology of influenza viruses, as well as the epidemiology of human or animal influenza, is poorly understood in the region. In particular, little is known about swine influenza in Africa despite the relevance of this production in the continent and the widespread pig husbandry operations in urban and rural areas. In this review, the gap in the knowledge of classical and pandemic swine influenza is attributed to negligence of disease surveillance, as well as to the economic and public health impact that the disease may cause in sub-Saharan Africa. However, emerging serological and virological evidence of swine influenza virus in some countries in the region underscores the importance of integrated surveillance to better understand the circulation and epidemiology of swine influenza, a disease of global economic and public health importance.

    The retinoids are a pharmacologic class based on the vitamin A or retinol. The most known related derivatives are the all-trans (ATRA), 13 and 9 Cis retinoic acids. The antitumor and differenciative activities have been demonstrated in: in vitro, in vivo and clinical studies. In head and neck cancers, the clinical phase III trials in chemoprevention of second primary tumors have shown discordant results related to the type of retinoic acid. Nuclear retinoic acid receptors are members of the steroid-thyroid and vitamin D3 superfamily of nuclear receptors which regulate differenciation proliferation and apoptosis in cooperation with mediated proteins of the apoptosis (especially p53 protein). A thorough knowledge on the earlier mechanisms involved in carcinogenesis of squamous cell carcinomas would lead to futur reversal therapy with the reversal of pathologic to normal tissues by the restauration of mechanisms of the physiologic control. This futur clinical trial research could provide cancer prevention and control by the induction of cellular differentiation rather than proliferation (retinoids) and/or the expression of tumor-suppressor genes (p53 protein transfection). Finally, the retinoids treatment should be performed in control studies because of the toxicity at high doses.

    Chronic pancreatitis is a complex disease both for the epidemiology, with uncertain data on the exact prevalence, but also for the etiology, often not identified and for whom, compared to the past, post acute pancreatitis forms are showing a high impact; also smoking is an etiological factor often underestimated compared to alcohol. Chronic pancreatitis is associated with high mortality and morbidity, mostly due to extrapancreatic diseases. The eventual occurrence of exocrine or endocrine pancreatic insufficiency can lead to complications, often serious and not prevented in time. It is, in fact, well known how this can cause micro or macronutrient and vitamin deficit which, if not screened and corrected, can cause complications such as osteoporosis. Abdominal pain is the most relevant symptom, with a complex pathogenesis, due not only to obstructive or mechanical factors or inflammation, but also to a chronic alteration of the adaptation process of pain in the central nervous system. Also for this reason, therapies are often not effective. Derivative surgery is indicated in obstructive forms, with results superior to those of endoscopy, while resective surgery is indicated when an inflammatory mass is present. A new opportunity is total pancreatectomy with islet autotransplantation, which offers excellent results in terms of pain relief and possibility to avoid diabetes in a high percentage of patients. This review will discuss these hot topics comprehending both most recent evidence and a view on how our knowledge on this disease will change in the upcoming years. PMID:27362725

  8. Terrestrial movement energetics: current knowledge and its application to the optimising animal.

    PubMed

    Halsey, Lewis G

    2016-05-15

    The energetic cost of locomotion can be a substantial proportion of an animal's daily energy budget and thus key to its ecology. Studies on myriad species have added to our knowledge about the general cost of animal movement, including the effects of variations in the environment such as terrain angle. However, further such studies might provide diminishing returns on the development of a deeper understanding of how animals trade-off the cost of movement with other energy costs, and other ecological currencies such as time. Here, I propose the 'individual energy landscape' as an approach to conceptualising the choices facing the optimising animal. In this Commentary, first I outline previous broad findings about animal walking and running locomotion, focusing in particular on the use of net cost of transport as a metric of comparison between species, and then considering the effects of environmental perturbations and other extrinsic factors on movement costs. I then introduce and explore the idea that these factors combine with the behaviour of the animal in seeking short-term optimality to create that animal's individual energy landscape - the result of the geographical landscape and environmental factors combined with the animal's selected trade-offs. Considering an animal's locomotion energy expenditure within this context enables hard-won empirical data on transport costs to be applied to questions about how an animal can and does move through its environment to maximise its fitness, and the relative importance, or otherwise, of locomotion energy economy.

    Santiago Ramón y Cajal developed a great body of scientific research during the last decade of 19th century, mainly between 1888 and 1892, when he published more than 30 manuscripts. The neuronal theory, the structure of dendrites and spines, and fine microscopic descriptions of numerous neural circuits are among these studies. In addition, numerous cell types (neuronal and glial) were described by Ramón y Cajal during this time using this “reazione nera” or Golgi method. Among these neurons were the special cells of the molecular layer of the neocortex. These cells were also termed Cajal cells or Retzius cells by other colleagues. Today these cells are known as Cajal–Retzius cells. From the earliest description, several biological aspects of these fascinating cells have been analyzed (e.g., cell morphology, physiological properties, origin and cellular fate, putative function during cortical development, etc). In this review we will summarize in a temporal basis the emerging knowledge concerning this cell population with specific attention the pioneer studies of Santiago Ramón y Cajal. PMID:24904301

    Worldwide, 500 million people a year acquire a sexually transmitted disease (STD). Adolescents, accounting for 25% of the sexually active population, are the most affected. To analyze sexual behavior among Italian adolescents and their knowledge of STDs, with the goal of preventing their transmission, a questionnaire was administered to 2867 secondary school students (1271 males and 1596 females) aged 14–21 years. For the study, 1492 students were interviewed in Genoa (Northern Italy) and 1375 in Lecce (Southern Italy). For 37% of the respondents, parents and teachers were the main source of information on sex, and 95% believed that school should play the primary role in sex education. However, only 9% considered the sex education they received in school good. Noteworthy, only 0.5% of the teenagers recognized the sexually transmitted diseases from a list of diseases, and 54% of them did not know what a Pap test was. Confusion about the meaning of contraception and prevention was evident; only 22% knew that condoms and abstinence are the only methods for preventing STDs. Finally, a consistent number of students are exposed to risk factors for STDs transmission; e.g., alcohol and recreational drug use, promiscuity and improper condom use. On the basis of our study, there is an urgent need for the introduction of sex education as a proper subject in Italian schools. PMID:27089354

    2012-01-01

    Antibiotics are widely used in the therapy of infections. Besides the respective interactions between antibiotics and pathogens it seems that antibiotics also directly interact with the immune system. Some commonly used antibiotics are currently known to have effects on the innate immune response, as shown by in vitro, ex vivo and also in vivo animal experiments and clinical studies. Most of the experimental papers published to date, as well as most reviews, relate to how antibiotics affect the innate immune response or non-specific monocyte or lymphocyte proliferation. However the effects of antibiotics on the adaptive immune response are still not well characterized. This review of the literature considering different in vivo experiments indicate the real importance of interrelations existing between acquired immune responses and antibiotics, however, the mechanism of immunomodulatory effects of antibiotics are still poorly understood. Currently, data on the immunomodulating effects of antibiotics often remain heterogeneous, contradictory or insufficient, but most results published to date revealed the immunosuppressive effect of antibiotics on the antigen-specific immune response in vivo. In pigs as well as in poultry herds, it is not uncommon practice to add antibiotics to drinking water or feed at the time of vaccination. Information on the effects of such practices on the immune system of animals is restricted and more in vivo studies are needed to investigate the effects of antimicrobial drugs on the immune system, especially in the field conditions.

    Genetics is an essential subject to be mastered by health professional students of all types. However, technological advances in genomics and recent pedagogical research have changed the way in which many medical training programs teach genetics to their students. These advances favor a more experience-based education focused primarily on developing student’s critical thinking skills. In this review, we examine the current state of genetics education at both the preclinical and clinical levels and the ways in which medical and pedagogical research have guided reforms to current and emerging teaching practices in genetics. We discover exciting trends taking place in which genetics is integrated with other scientific disciplines both horizontally and vertically across medical curricula to emphasize training in scientific critical thinking skills among students via the evaluation of clinical evidence and consultation of online databases. These trends will produce future health professionals with the skills and confidence necessary to embrace the new tools of medical practice that have emerged from scientific advances in genetics, genomics, and bioinformatics.

    Mycoplasma pneumoniae (M. pneumoniae) belongs to the class Mollicutes and has been recognized as a common cause of respiratory tract infections (RTIs), including community-acquired pneumonia (CAP), that occur worldwide and in all age groups. In addition, M. pneumoniae can simultaneously or sequentially lead to damage in the nervous system and has been associated with a wide variety of other acute and chronic diseases. During the past 10 years, the proportion of LRTI in children and adults, associated with M. pneumoniae infection has ranged from 0 to more than 50%. This variation is due to the age and the geographic location of the population examined but also due to the diagnostic methods used. The true role of M. pneumoniae in RTIs remains a challenge given the many limitations and lack of standardization of the applied diagnostic tool in most cases, with resultant wide variations in data from different studies. Correct and rapid diagnosis and/or management of M. pneumoniae infections is, however, critical to initiate appropriate antibiotic treatment and is nowadays usually done by PCR and/or serology. Several recent reviews, have summarized current methods for the detection and identification of M. pneumoniae. This review will therefore provide a look at the general principles, advantages, diagnostic value, and limitations of the most currently used detection techniques for the etiological diagnosis of a M. pneumoniae infection as they evolve from research to daily practice.

    Background The African oil palm (Elaeis guineensis) is a monoecious species of the palm subfamily Arecoideae. It may be qualified as ‘temporally dioecious’ in that it produces functionally unisexual male and female inflorescences in an alternating cycle on the same plant, resulting in an allogamous mode of reproduction. The ‘sex ratio’ of an oil palm stand is influenced by both genetic and environmental factors. In particular, the enhancement of male inflorescence production in response to water stress has been well documented. Scope This paper presents a review of our current understanding of the sex determination process in oil palm and discusses possible insights that can be gained from other species. Although some informative phenological studies have been carried out, nothing is as yet known about the genetic basis of sex determination in oil palm, nor the mechanisms by which this process is regulated. Nevertheless new genomics-based techniques, when combined with field studies and biochemical and molecular cytological-based approaches, should provide a new understanding of the complex processes governing oil palm sex determination in the foreseeable future. Current hypotheses and strategies for future research are discussed. PMID:21712294

    Cassava (Manihot esculenta Crantz) is one of the most important staple crops worldwide. It constitutes the major source of carbohydrates for millions of low-income people living in rural areas, as well as a cash crop for smallholders in tropical and sub-tropical regions. The Food and Agriculture Organization of the United Nations predicts that cassava plantations will increase and production systems will intensify in the future, highlighting the need for developing strategies that improve the sustainability of production. Plant chemical defenses hold the potential for developing pest management strategies, as these plant traits can influence the behavior and performance of both pests and beneficial arthropods. Cassava plants are well-defended and produce a number of compounds involved in direct defense, such as cyanogenic glycosides, flavonoid glycosides, and hydroxycoumarins. In addition, volatile organic compounds induced upon herbivory and the secretion of extrafloral nectar act as indirect defense against herbivores by recruiting natural enemies. Here, cassava chemical defenses against pest arthropods are reviewed, with the aim of identifying gaps in our knowledge and areas of research that deserve further investigation for developing sound pest control strategies to improve sustainable production of this crop, and how these defenses can be used to benefit other crops. Cyanogenic content in cassava is also highly toxic to humans, and can cause irreversible health problems even at sub-lethal doses when consumed over prolonged periods. Therefore, the promotion of chemical defense in this crop should not aggravate these problems, and must be accompanied with the education on processing methods that reduce human exposure to cyanide.

    For centuries, the planet Mars has been imagined as a possible abode for life. Serious searches for life's signatures began in the 19th century via ground-based visual astronomy that stimulated a vibrant fantasy literature but little lasting scientific knowledge. Modern scientific inquiry has emphasized the search for chemical signatures of life in the soil and rocks at the planet's surface, and via biomarker gases in the atmosphere. Today, investigations are based on high-resolution spectroscopy at Earth's largest telescopes along with planet orbiting and landed space missions. Methane has assumed central importance in these searches. Living systems produce more than 900/0 of Earth's atmospheric methane; the balance is of geochemical origin. Abundant methane is not expected in an oxidizing atmosphere such as Mars', and its presence would imply recent release - whether biological or geochemical. F or that reason, the quest for methane on Mars has been a continuing thread in the fabric of searches conducted since 1969. I will review aspects of the discovery and distribution of methane on Mars, and will mention ongoing extended searches for clues to its origin and destruction. On Earth, hydrogen (generated via serpentinization or radiolysis of water) provides an important 'fuel' for carbonate-reducing and sulphate-reducing biota (CH4 and H2S producers, respectively). Several such communities are known to reside at depth in continental domains (e.g., Lidy Hot Springs, Idaho; Witwatersrand Basin, S. Africa). If similar conditions exist in favourable locations on Mars, organisms similar to these could likely prosper there. Geologic (abiotic) production will also be mentioned, especially abiotic methane production associated with low-temperature serpentinization (e.g., terrestrial ophiolites). It is vitally important to pursue evidence for geochemical and biological production with equal vigour and intellectual weight lest unwanted and unintended bias contaminate the

    In the past few decades, several devastating heat wave events have significantly challenged public health. As these events are projected to increase in both severity and frequency in the future, it is important to assess the relationship between heat waves and the health indicators that can be used in the early warning systems to guide the public health response. Yet there is a knowledge gap in the impact of heat waves on morbidity. In this study, a comprehensive review was conducted to assess the relationship between heat waves and different morbidity indicators, and to identify the vulnerable populations. The PubMed and ScienceDirect database were used to retrieve published literature in English from 1985 to 2014 on the relationship between heat waves and morbidity, and the following MeSH terms and keywords were used: heat wave, heat wave, morbidity, hospital admission, hospitalization, emergency call, emergency medical services, and outpatient visit. Thirty-three studies were included in the final analysis. Most studies found a short-term negative health impact of heat waves on morbidity. The elderly, children, and males were more vulnerable during heat waves, and the medical care demand increased for those with existing chronic diseases. Some social factors, such as lower socioeconomic status, can contribute to heat-susceptibility. In terms of study methods and heat wave definitions, there remain inconsistencies and uncertainties. Relevant policies and guidelines need to be developed to protect vulnerable populations. Morbidity indicators should be adopted in heat wave early warning systems in order to guide the effective implementation of public health actions.

    A functioning referral system is generally considered to be a necessary element of successful Safe Motherhood programmes. This paper draws on a scoping review of available literature to identify key requisites for successful maternity referral systems in developing countries, to highlight knowledge gaps, and to suggest items for a future research agenda. Key online social science, medical and health system bibliographic databases, and websites were searched in July 2004 for evidence relating to referral systems for maternity care. Documentary evidence on implementation is scarce, but it suggests that many healthcare systems in developing countries are failing to optimise women's rapid access to emergency obstetric care, and that the poor and marginalised are affected disproportionately. Likely requisites for successful maternity referral systems include: a referral strategy informed by the assessment of population needs and health system capabilities; an adequately resourced referral centre; active collaboration between referral levels and across sectors; formalised communication and transport arrangements; agreed setting-specific protocols for referrer and receiver; supervision and accountability for providers' performance; affordable service costs; the capacity to monitor effectiveness; and underpinning all of these, policy support. Theoretically informed social and organisational research is required on the referral care needs of the poor and marginalised, on the maternity workforce and organisation, and on the implications of the mixed economy of healthcare for referral networks. Clinical research is required to determine how maternity referral fits within newborn health priorities and where the needs are different. Finally, research is required to determine how and whether a more integrated approach to emergency care systems may benefit women and their communities.

    It is known that antimicrobial agents possess several, beneficial, secondary properties which complement their primary antimicrobial activity like the immunomodulatory capacity that enforces host defense mechanisms or reduces host inflammatory response. In this review the current state of our recent research about the interaction between some antimicrobial agents and the immune system as complex pyramid of redundant cellular factors, humoral effectors and mediators against various microbial pathogens, will be presented and compared with recent literature data. The nature of such interactions is diverse and depends on the drug, the host immunological status and the microorganism. A more complete understanding of the host immune modulation by antimicrobial drugs may guide the selection of appropriate regimens for given clinical situations.

    Motor symptomatology in autism is currently poorly understood, and still not included in the autism spectrum disorder (ASD) diagnostic criteria, although some studies suggest the presence of motor disturbances in this syndrome. We provide here a literature review on early motor symptoms in autism, focusing on studies on psychomotor issues (tone, postural control, manual dexterity, handedness, praxis). The approach adopted in research to study altered motor behaviors is generally global and there is no detailed semiology of the motor or neuromotor disorders observed in people with ASD. This global approach does not enable understanding of the neuro-developmental mechanisms involved in ASD. Identification of clinical neuro-psychomotor profiles in reference to a standard would help to better understand the origin and the nature of the disorders encountered in ASD, and would thus give new directions for treatment.

    Diving-related decompression illness is classified into 2 main categories: arterial gas embolism and decompression sickness. The latter is further divided into types 1 and 2, depending on the clinical presentation. MR imaging is currently the most accurate neuroimaging technique available for the detection of brain and spinal cord lesions in neurologic type 2 decompression sickness. Rapid bubble formation in tissues and the bloodstream during ascent is the basic pathophysiologic mechanism in decompression illness. These bubbles can damage the central nervous system through different mechanisms, namely arterial occlusion, venous obstruction, or in situ toxicity. Neuroimaging studies of decompression sickness have reported findings associated with each of these mechanisms: some typical results are summarized and illustrated in this article. We also review the limitations of previous work and make practical methodologic suggestions for future neuroimaging studies.

    Using forests to mitigate climate change has gained much interest in science and policy discussions. We examine the evidence for carbon benefits, environmental and monetary costs, risks and trade-offs for a variety of activities in three general strategies: (1) land use change to increase forest area (afforestation) and avoid deforestation; (2) carbon management in existing forests; and (3) the use of wood as biomass energy, in place of other building materials, or in wood products for carbon storage. We found that many strategies can increase forest sector carbon mitigation above the current 162-256 Tg C/yr, and that many strategies have co-benefits such as biodiversity, water, and economic opportunities. Each strategy also has trade-offs, risks, and uncertainties including possible leakage, permanence, disturbances, and climate change effects. Because approximately 60% of the carbon lost through deforestation and harvesting from 1700 to 1935 has not yet been recovered and because some strategies store carbon in forest products or use biomass energy, the biological potential for forest sector carbon mitigation is large. Several studies suggest that using these strategies could offset as much as 10-20% of current U.S. fossil fuel emissions.

    Using forests to mitigate climate change has gained much interest in science and policy discussions. We examine the evidence for carbon benefits, environmental and monetary costs, risks and trade-offs for a variety of activities in three general strategies: (1) land use change to increase forest area (afforestation) and avoid deforestation; (2) carbon management in existing forests; and (3) the use of wood as biomass energy, in place of other building materials, or in wood products for carbon storage. We found that many strategies can increase forest sector carbon mitigation above the current 162-256 Tg C/yr, and that many strategies have co-benefits such as biodiversity, water, and economic opportunities. Each strategy also has trade-offs, risks, and uncertainties including possible leakage, permanence, disturbances, and climate change effects. Because approximately 60% of the carbon lost through deforestation and harvesting from 1700 to 1935 has not yet been recovered and because some strategies store carbon in forest products or use biomass energy, the biological potential for forest sector carbon mitigation is large. Several studies suggest that using these strategies could offset as much as 10-20% of current U.S. fossil fuel emissions. To obtain such large offsets in the United States would require a combination of afforesting up to one-third of cropland or pastureland, using the equivalent of about one-half of the gross annual forest growth for biomass energy, or implementing more intensive management to increase forest growth on one-third of forestland.

  10. Social stress as a cause of diseases in farm animals: Current knowledge and future directions.

    Over the past 50 years, biomedical research has established a strong linkage between psychosocial stress and disease risk in humans, which has transformed the understanding of stress and the role it plays in human lives. This research has led to personalized medicine where a reduction in daily life stress is a main goal for many people with debilitating illnesses. This review describes the supporting evidence that social stress also plays a critical role in farm animal disease prevention, and may be a mediator by which common management practices can increase disease risk. There is evidence that social factors, including deprivation of social contact ('social isolation'), reducing space allowance ('crowding') and disturbing social order ('social instability') trigger physiological and behavioral indicators of stress in livestock. Less research exists, however, linking management practices that trigger social stress with higher disease risk. Suggestions are offered for future research opportunities, and practical, evidence-based recommendations are made for reducing the negative effects of social isolation, instability and crowding. The current evidence that social factors contribute to disease risk in farm animals is not as convincing as the human literature, but remains a promising and important area for future research.

  11. Current knowledge of coffee wilt disease, a major constraint to coffee production in Africa.

    ABSTRACT Coffee is vital to the economy of East and Central Africa, providing a major source of foreign exchange earnings and, as a cash crop, supporting the livelihoods of millions involved in cultivation, processing, marketing, and export. Coffee wilt disease (CWD), attributed to Gibberella xylarioides (Fusarium xylarioides), has caused losses to coffee production in Africa since 1927 but has been largely contained through the use of host resistance and in some instances wide-scale sanitation practices. A reemergence of CWD on Coffea canephora (Robusta coffee) in Uganda, Democratic Republic of Congo, and Tanzania has already led to heavy losses and threatens future production in these countries and elsewhere in the region. The relevance of CWD is all the more pertinent given the impact of a considerable fall in world coffee prices over the last decade. Recent research has clarified the extent of the problem in the region and revealed a low level of diversity within the pathogen, suggesting that two genetically and biologically distinct forms are responsible for current problems. These findings and related research and development initiatives undertaken under the auspices of the Regional Coffee Wilt Programme are of fundamental importance in providing an urgently needed solution to this devastating disease.

    As the tests for detecting growth hormone (GH) abuse develop further, it is likely that athletes will turn to doping with insulin-like growth factor-I (IGF-I). IGF-I mediates many of the anabolic actions of growth hormone. It stimulates muscle protein synthesis, promotes glycogen storage and enhances lipolysis, all of which make IGF-I attractive as a potential performance-enhancing agent. Pharmaceutical companies have developed commercial preparations of recombinant human IGF-I (rhIGF-I) for use in disorders of growth. The increased availability of rhIGF-I increases the opportunity for athletes to acquire supplies of the drug on the black market. The long-term effects of IGF-I administration are currently unknown but it is likely that these will be similar to the adverse effects of chronic GH abuse. The detection of IGF-I abuse is a challenge for anti-doping organisations. Research has commenced into the development of a test for IGF-I abuse based on the measurement of markers of GH action. Simultaneously, the effects of rhIGF-I on physical fitness, body composition and substrate utilisation in healthy volunteers are being investigated.

    Bruxism is commonly considered a detrimental motor activity, potentially causing overload of the stomatognathic structures and representing a risk factor for dental implant survival. The available literature does not provide evidence-based guidelines for the management of bruxers undergoing implant-retained restorations. The present paper reviewed current concepts on bruxism etiology, diagnosis and management, underlining its effects on dental implants in an attempt to provide clinically useful suggestions based on scientifically sound data. Unfortunately, very little data exists on the subject of a cause-and-effect relationship between bruxism and implant failure, to the point that expert opinions and cautionary approaches are still considered the best available sources for suggesting good practice indicators. By including experimental literature data on the effects of different types of occlusal loading on peri-implant marginal bone loss along with data from studies investigating the intensity of the forces transmitted to the bone itself during tooth-clenching and tooth-grinding activities, the authors were able to compile the suggestions presented here for prosthetic implant rehabilitations in patients with bruxism.

    2012-01-01

    Chronic complications of symptomatic gallstone disease, such as Mirizzi syndrome, are rare in Western developed countries with an incidence of less than 1% a year. The importance and implications of this condition are related to their associated and potentially serious surgical complications such as bile duct injury, and to its modern management when encountered during laparoscopic cholecystectomy. The pathophysiological process leading to the subtypes of Mirizzi syndrome has been explained by means of a pressure ulcer caused by an impacted gallstone at the gallbladder infundibulum, leading to an inflammatory response causing first external obstruction of the bile duct, and eventually eroding into the bile duct and evolving to a cholecystocholedochal or cholecystohepatic fistula. This article reviews the life of Pablo Luis Mirizzi, describes the earlier and later descriptions of Mirizzi syndrome, discusses the pathophysiological process leading to the development of these uncommon fistulas, reviews the current diagnostic modalities and surgical approaches and finally proposes a simplified classification for Mirizzi syndrome intended to standardize the reports on this condition and to eventually develop a consensual surgical approach to this unexpected and seriously dangerous condition.

    The importance of associations between microorganisms and their invertebrate hosts is becoming increasingly apparent. An emerging field, driven by the necessity to understand the microbial relationships that both maximize coral health and cause coral disease, is the study of coral-bacteria interactions. In this article, we review our current understanding of the diversity, specificity, development, and functions of coral-associated bacteria. We also summarize what is known regarding the role of coral microbiota in the health and disease of coral. We conduct a meta-analysis to determine whether the presence of unique taxa correlates with the state of coral health (i.e. healthy, diseased or bleached), as well as whether coral reef habitats harbor clusters of distinct taxa. We find that healthy and bleached corals harbor similar dominant taxa, although bleached corals had higher proportions of Vibrio and Acidobacteria. Diseased corals generally had more Rhodobacter, Clostridia, and Cyanobacteria sequences, and fewer Oceanospirillum sequences. We caution, however, that while 16S rRNA is useful for microbial species identification, it is a poor predictor of habitat or lifestyle, and care should be taken in interpretation of 16S rRNA surveys to identify potential pathogens amongst complex coral-microbial assemblages. Finally, we highlight evidence that coral-bacterial assemblages could be sensitive to the effects of climatic change. We suggest that the relationship between coral and their bacterial associates represents a valuable model that can be applied to the broader discipline of invertebrate-microbial interactions.

  16. The current state of knowledge about shatter cones: Introduction to the special issue

    2016-08-01

    Shatter cones are a fracture phenomenon that is exclusively associated with shock metamorphism and has also been produced in the laboratory in several shock experiments. The occurrence of shatter cones is the only accepted meso- to macroscopic recognition criterion for impact structures. Shatter cones exhibit a number of geometric characteristics (orientation, apical angles, striation angles, sizes) that can be best described as varied, from case to case. Possible links between geometric properties with impact or crater parameters have remained controversial and the lack of understanding of the mechanism of formation of shatter cones does not offer a physical framework to discuss or understand them. A database of shatter cone occurrences has been produced for this introduction paper to the special issue of Meteoritics and Planetary Science on shatter cones. Distribution of shatter cones with respect to crater size and lithology suggests that shatter cones do not occur in impact craters less than a few kilometers in diameter, with a few, currently questionable exceptions. All pertinent hypotheses of formation are presented and discussed. Several may be discarded in light of the most recent observations. The branching fracture mechanism and the interference models proposed, respectively, by Sagy et al. (2002) and Baratoux and Melosh (2003) require further evaluation. New observations, experiments, or theoretical considerations presented in this special issue promise an important step forward, based on a renewed effort to resolve the enigmatic origin of these important features.

    We review present understanding of the spatial and temporal diet variability (trophodynamics) of a range of pelagic marine top predators, at both early and adult life history stages. We begin with a review of methodologies used to advance our understanding of the trophodynamics of marine top predators, particularly in relation to climate change. We then explore how these developments are informing our understanding of the major trophic groups in food webs leading to, and including, marine top predators. We examine through specific examples how the impacts of ocean warming may affect pelagic food web relationships from both top-down and bottom-up perspectives. We examine the potential, in the absence of long-term data sets, of using large-scale spatial studies to examine how potential changes in biological oceanography could impact the biomass and composition of prey species, particularly the role of phytoplankton size spectra. We focus on examples from regions where biotic change with respect to climate change is likely. In particular, we detail the effects of climate change on oceanographic and bathymetric "hotspots" and provide the example involving seabirds in the Benguela Current system. We end by urging the development of international collaborations and databases to facilitate comprehensive ocean-scale understanding of climate impacts on marine top predators.

    Delivery of medications to the inner ear has been an area of considerable growth in both the research and clinical realms over the past several decades. Systemic delivery of medication destined for treatment of the inner ear is the foundation upon which newer delivery techniques have been developed. Due to systemic side effects, investigators and clinicians have begun developing and utilizing techniques to deliver therapeutic agents locally. Alongside the now commonplace use of intratympanic gentamicin for Meniere's disease and the emerging use of intratympanic steroids for sudden sensorineural hearing loss, novel technologies, such as hydrogels and nanoparticles, are being explored. At the horizon of inner ear drug delivery techniques, intracochlear devices that leverage recent advances in microsystems technology are being developed to apply medications directly into the inner ear. Potential uses for such devices include neurotrophic factor and steroid delivery with cochlear implantation, RNA interference technologies, and stem cell therapy. The historical, current, and future delivery techniques and uses of drug delivery for treatment of inner ear disease serve as the basis for this review. PMID:19952751

    Vaccination is the most adequate method to control infectious diseases that threaten the aquaculture industry worldwide. Unfortunately, vaccines are usually not able to confer protection on their own; especially those vaccines based on recombinant antigens or inactivated pathogens. Therefore, the use of adjuvants or immunostimulants is often necessary to increase the vaccine efficacy. Traditional adjuvants such as mineral oils are routinely used in different commercial bacterial vaccines available for fish; however, important side effects may occur with this type of adjuvants. A search for alternative molecules or certain combinations of them as adjuvants is desirable in order to increase animal welfare without reducing protection levels. Especially, combinations that may target specific cell responses and thus a specific pathogen, with no or minor side effects, should be explored. Despite this, the oil adjuvants currently used are quite friendlier with respect to side effects compared with the oil adjuvants previously used. The great lack of fish antiviral vaccines also evidences the importance of identifying optimal combinations of a vaccination strategy with the use of a targeting adjuvant, especially for the promising fish antiviral DNA vaccines. In this review, we summarise previous studies performed with both traditional adjuvants as well as the most promising new generation adjuvants such as ligands for Toll receptors or different cytokines, focussing mostly on their protective efficacies, and also on what is known concerning their effects on the fish immune system when delivered in vivo.

    Since the reinfestation of South American countries by Ae. aegypti, dengue fever (DF) and dengue hemorrhagic fever (DHF) have become a major public health concern. The aim of this paper was to review the information related with Aedes vectors and dengue in Argentina since the reintroduction of Ae. aegypti in 1986. The geographic distribution of Ae. albopictus is restricted to the Northeast, and that of Ae. aegypti has expanded towards the South and the West in comparison with the records during the eradication campaign in the 1960s. Since 1998, 4,718 DF cases have been reported concentrated in the provinces of Salta, Formosa, Misiones, Jujuy and Corrientes. Despite the circulation of three dengue virus serotypes (DENV-1, -2 and -3) in the North of the country, DHF has not occurred until the present. The information published over the last two decades regarding mosquito abundance, temporal variations, habitat characteristics, competition, and chemical and biological control, was reviewed. Considering the available information, issues pending in Argentina are discussed. The presence of three DENV, the potential spread of Ae. albopictus, and the predicted climate change suggest that dengue situation will get worse in the region. Research efforts should be increased in the Northern provinces, where DHF is currently an actual risk.

    The recent availability of high-throughput nucleic acid sequencing technologies has rapidly advanced approaches to analysing the role of the gut microbiome in governance of human health, including gut health, and also metabolic, cardiovascular and mental health, inter alia. Recent scientific studies suggest that energy intake (EI) perturbations at the population level cannot account for the current obesity epidemic, and significant work is investigating the potential role of the microbiome, and in particular its metabolic products, notably SCFA, predominantly acetate, propionate and butyrate, the last of which is an energy source for the epithelium of the large intestine. The energy yield from dietary residues may be a significant factor influencing energy balance. This review posits that the contribution towards EI is governed by EI diet composition (not just fibre), the composition of the microbiome and by the levels of physical activity. Furthermore, we hypothesise that these factors do not exist in a steady state, but rather are dynamic, with both short- and medium-term effects on appetite regulation. We suggest that the existing modelling strategies for bacterial dynamics, specifically for growth in chemostat culture, are of utility in understanding the dynamic interplay of diet, activity and microbiomic organisation. Such approaches may be informative in optimising the application of dietary and microbial therapy to promote health.

    Southern Podlasie is a specific region as regards HIV/AIDS hazards for its geographical position (border zone) as well as social problems (high level of unemployment). The aim of the research was to find out the level of knowledge of rural youth on the subject of risk factors and ways of spreading HIV as well as AIDS clinic. 405 students aged 15-17 (197 males and 208 females) that attend chosen rural schools on the territory of Southern Podlasie were questioned. The method of diagnostic poll was employed in the research using the questionnaire "HIV/AIDS knowledge and beliefs" from international studies on school youth health preservation (HBSC)--the supervisor of the project in Poland is professor B. Woynarowska). The research has shown different levels of knowledge of rural youth on the subject of HIV/AIDS. There were still many false opinions among the people questioned about the ways of HIV infection. Despite considerable knowledge about the ways of reducing the risk of HIV infection, there was low level of knowledge concerning AIDS treatment compared with the results of nationwide survey, there were fewer correct answers in our study group. It is the duty of schools, parents and mass media to provide the youth with relevant information on the subject of HIV/AIDS. Only systematic education in this domain can protect the infected persons and their partners or children against the consequences of ignoring the disease.

    Accurate assessment of early hip joint cartilage alterations may help optimize patient selection and follow-up of hip joint preservation surgery. Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) is sensitive to the glycosaminoglycan content in cartilage that is lost early in the development of osteoarthritis (OA). Hence, the dGEMRIC technique holds promise for the development of new diagnostic and therapeutic procedures. However, because of the location of the hip joint deep within the body and due to the fairly thin cartilage layers that require high spatial resolution, the diagnosis of early hip joint cartilage alterations may be problematic. The purpose of this review is to outline the current status of dGEMRIC in the assessment of hip joint cartilage. A literature search was performed with PubMed, using the terms "cartilage, osteoarthritis, hip joint, MRI, and dGEMRIC", considering all levels of studies. This review revealed that dGEMRIC can be reliably used in the evaluation of early stage cartilage pathology in various hip joint disorders. Modifications in the technique, such as the operation of three-dimensional imaging and dGEMRIC after intra-articular contrast medium administration, have expanded the range of application. Notably, the studies differ considerably in patient selection and technical prerequisites. Furthermore, there is a need for multicenter prospective studies with the required technical conditions in place to establish outcome based dGEMRIC data to obtain, in conjunction with clinical data, reliable threshold values for normal and abnormal cartilage, and for hips that may benefit from conservative or surgical treatment.

    Due to particular social and economical development, and to the impact of globalization of lifestyles, Latin America shows a superposition of cancers that are frequent in low resource countries (gastric, oesophageal squamous cell and cervical cancers) and high resource countries (cancers of breast, colon and rectum, lung and prostate). Latin America thus offers opportunities for investigating the impact on changing lifestyle patterns on the occurrence of cancer. At the molecular level, mutations in the tumor suppressor gene TP53 are common in many cancers and their distribution can be informative of the nature of the mutagenic mechanisms, thus giving clues to cancer etiology and molecular pathogenesis. However most of the data available are derived from studies in industrialized countries. In this review, we discuss current trends on cancer occurrence in Latin American countries, and we review the literature available on TP53 mutations and polymorphisms in patients from Latin America. Overall, a total of 285 mutations have been described in 1213 patients in 20 publications, representing 1.5% of the total number of mutations reported world-wide. Except for hematological cancers, TP53 mutation frequencies are similar to those reported in other regions of the world. The only tumor site presenting significant differences in mutation pattern as compared to other parts of the world is colon and rectum. However, this difference is based on a single study with 35 patients. Recently, a characteristic TP53 mutation at codon 337 (R337H) has been identified in the germline of children with adrenocortical carcinoma in Southern Brazil. Further and better focused analyses of TP53 mutation patterns in the context of epidemiological studies, should help to improve our understanding of cancer etiology in order to develop appropriate health policies and public health programs in Latin America.

    Men who sleep with men (MSM) and transgender individuals of color, the largest demographic in the House Ball community (HBC) are amongst the group at highest risk for HIV infection in the United States. The HBC have limited access to culturally appropriate HIV education. This study aimed to develop a partnership with HBC leaders to uncover strategies for increasing HIV prevention knowledge, including participation in HIV vaccine trials. To this end a research institution-community-HBC partnership was established. In-depth qualitative and quantitative data were collected from the 14 HBC leaders in western New York, revealing that knowledge of HIV and related vaccine trials was limited. Barriers to increasing HIV knowledge included fear of peer judgment, having inaccurate information about HIV, and lack of education. Among the HBC, community partnerships will further aid in the development of future HIV prevention programs and increase individuals’ willingness to participate in future HIV vaccine trials.

    Continental South Africa has a coastline of some 3,650 km and an Exclusive Economic Zone (EEZ) of just over 1 million km(2). Waters in the EEZ extend to a depth of 5,700 m, with more than 65% deeper than 2,000 m. Despite its status as a developing nation, South Africa has a relatively strong history of marine taxonomic research and maintains comprehensive and well-curated museum collections totaling over 291,000 records. Over 3 million locality records from more than 23,000 species have been lodged in the regional AfrOBIS (African Ocean Biogeographic Information System) data center (which stores data from a wider African region). A large number of regional guides to the marine fauna and flora are also available and are listed. The currently recorded marine biota of South Africa numbers at least 12,914 species, although many taxa, particularly those of small body size, remain poorly documented. The coastal zone is relatively well sampled with some 2,500 samples of benthic invertebrate communities have been taken by grab, dredge, or trawl. Almost none of these samples, however, were collected after 1980, and over 99% of existing samples are from depths shallower than 1,000 m--indeed 83% are from less than 100 m. The abyssal zone thus remains almost completely unexplored. South Africa has a fairly large industrial fishing industry, of which the largest fisheries are the pelagic (pilchard and anchovy) and demersal (hake) sectors, both focused on the west and south coasts. The east coast has fewer, smaller commercial fisheries, but a high coastal population density, resulting in intense exploitation of inshore resources by recreational and subsistence fishers, and this has resulted in the overexploitation of many coastal fish and invertebrate stocks. South Africa has a small aquaculture industry rearing mussels, oysters, prawns, and abalone-the latter two in land-based facilities.

Further research will be required to determine whether the current EG95 vaccine would be effective against the G6 or G7 genotypes, or whether it will be necessary, and possible, to develop genotype-specific vaccines.

    In 2008, between 129,000 and 194,000 of the 430,000 pediatric HIV infections worldwide were attributable to breastfeeding. Yet in many settings, the health, economic, and social consequences of not breastfeeding would have dire consequences for many more children. In the first part of this review we provide an overview of current knowledge about infant feeding in the context of HIV. Namely, we describe the benefits and risks of breastmilk, the evolution of recommended infant feeding modalities in high-income and low-income countries in the last two decades, and contextualize the recently revised guidelines for infant feeding in the context of HIV current knowledge. In the second section, we suggest areas for future research on the postnatal prevention of mother-to-child transmission of HIV (PMTCT) in developing and industrialized countries. We suggest two shifts in perspective. The first is to evaluate PMTCT interventions more holistically, to include the psychosocial and economic consequences as well as the biomedical ones. The second shift in perspective should be one that contextualizes postnatal PMTCT efforts in the cascade of maternal health services. We conclude by discussing basic, clinical, behavioral, and programmatic research questions pertaining to a number of PMTCT efforts, including extended postnatal ARV prophylaxis, exclusive breastfeeding promotion, counseling, breast milk pasteurization, breast milk banking, novel techniques for making breast milk safer, and optimal breastfeeding practices. We believe the research efforts outlined here will maximize the number of healthy, thriving, HIV-free children around the world. PMID:22332055

    Social network awareness (SNA) has been used extensively as one of the strategies to increase knowledge sharing and collaboration opportunities. However, most SNA studies either focus on being aware of peer's knowledge context or on social context. This work proposes online formative assessments with SNA, trying to address the problems of online…

    The current Ebola virus epidemic continues to pose a threat to the UK. Junior clinicians are often at the frontline of medical care in hospitals and their awareness of the clinical features and management of the Ebola virus disease (EVD) may significantly influence the timely implementation of infection control measures. In view of this, we carried out a cross-sectional survey of 119 junior doctors across four different hospitals in England in order to assess their level of knowledge of EVD. We demonstrate that there is currently a deficiency of knowledge about critical aspects of EVD in this population.

    Diabetes mellitus is a group of metabolic disorders in which the blood glucose is higher than normal levels, due to insufficiency of insulin release or improper response of cells to insulin, resulting in high blood pressure. The resultant hyperglycemia produces sever complications. Metformin drug has been shown to prevent diabetes in people who are at high risk and decrease most of the diabetic complications. Recent reports on metformin, not only indicate some implications such as renoprotective properties have been suggested for metformin, but some reports indicate its adverse effects as well that are negligible when its benefits are brought into account. We aimed here to review the new implications of metformin and discuss about the concerns in the use of metformin, referring to the recently published papers. PMID:25364368

    Development and optimisation of alternative strategies to reduce the use of classic chemical inputs for protection against diseases in vineyard is becoming a necessity. Among these strategies, one of the most promising consists in the stimulation and/or potentiation of the grapevine defence responses by the means of elicitors. Elicitors are highly diverse molecules both in nature and origins. This review aims at providing an overview of the current knowledge on these molecules and will highlight their potential efficacy from the laboratory in controlled conditions to vineyards. Recent findings and concepts (especially on plant innate immunity) and the new terminology (microbe-associated molecular patterns, effectors, etc.) are also discussed in this context. Other objectives of this review are to highlight the difficulty of transferring elicitors use and results from the controlled conditions to the vineyard, to determine their practical and effective use in viticulture and to propose ideas for improving their efficacy in non-controlled conditions.

    Background A myriad of interventions exist to treat postpartum hemorrhage (PPH), ranging from uterotonics and hemostatics to surgical and aortic compression devices. Nonetheless, PPH remains the leading cause of maternal mortality worldwide. The purpose of this article is to review the available evidence on the efficacy of misoprostol for the treatment of primary PPH and discuss implications for health care planning. Data and methods Using PubMed, Web of Science, and GoogleScholar, we reviewed the literature on randomized controlled trials of interventions to treat PPH with misoprostol and non-randomized field trials with controls. We discuss the current knowledge and implications for health care planning, especially in resource-poor settings. Results The treatment of PPH with 800 μg of misoprostol is equivalent to 40 IU of intravenous oxytocin in women who have received oxytocin for the prevention of PPH. The same dose might be an option for the treatment of PPH in women who did not receive oxytocin for the prevention of PPH and do not have access to oxytocin for treatment. Adding misoprostol to standard uterotonics has no additional benefits to women being treated for PPH, but the beneficial adjunctive role of misoprostol to conventional uterotonics is important in reducing intra- and postoperative hemorrhage during cesarean section. Conclusion Misoprostol is an effective uterotonic agent in the treatment of PPH. Clinical guidelines and treatment protocols should be updated to reflect the current knowledge on the efficacy of misoprostol for the treatment of PPH with 800 μg sublingually. PMID:27536161

    Benthic cyanobacteria are found globally in plethora of environments. Although they have received less attention than their planktonic freshwater counterparts, it is now well established that they produce toxins and reports of their involvement in animal poisonings have increased markedly during the last decade. Most of the known cyanotoxins have been identified from benthic cyanobacteria including: the hepatotoxic microcystins, nodularins and cylindrospermopsins, the neurotoxic saxitoxins, anatoxin-a and homoanatoxin-a and dermatotoxins, such as lyngbyatoxin. In most countries, observations of toxic benthic cyanobacteria are fragmented, descriptive and in response to animal toxicosis events. Only a limited number of long-term studies have aimed to understand why benthic proliferations occur, and/or how toxin production is regulated. These studies have shown that benthic cyanobacterial blooms are commonly a mixture of toxic and non-toxic genotypes and that toxin concentrations can be highly variable spatially and temporally. Physiochemical parameters responsible for benthic proliferation vary among habitat type with physical disturbance (e.g., flow regimes, wave action) and nutrients commonly identified as important. As climatic conditions change and anthropogenic pressures on waterways increase, it seems likely that the prevalence of blooms of benthic cyanobacteria will increase. In this article we review current knowledge on benthic cyanobacteria: ecology, toxin-producing species, variables that regulate toxin production and bloom formation, their impact on aquatic and terrestrial organisms and current monitoring and management strategies. We suggest research needs that will assist in filling knowledge gaps and ultimately allow more robust monitoring and management protocols to be developed.

    Universe Awareness (UNAWE) is an educational programme coordinated by Leiden University that uses the beauty and grandeur of the Universe to encourage young children, particularly those from an underprivileged background, to have an interest in science and technology and foster their sense of global citizenship from the earliest age.UNAWE's twofold vision uses our Universe to inspire and motivate very young children: the excitement of the Universe provides an exciting introduction to science and technology, while the vastness and beauty of the Universe helps broaden the mind and stimulate a sense of global citizenship and tolerance. UNAWE's goals are accomplished through four main activities: the coordination of a global network of more than 1000 astronomers, teachers and educators from more than 60 countries, development of educational resources, teacher training activities and evaluation of educational activities.Between 2011 and 2013, EU-UNAWE, the European branch of UNAWE, was funded by the European Commission to implement a project in 5 EU countries and South Africa. This project has been concluded successfully. Since then, the global project Universe Awareness has continued to grow with an expanding international network, new educational resources and teacher trainings and a planned International Workshop in collaboration with ESA in October 2015, among other activities.

    Background Wider adoption of reporting guidelines by veterinary journals could improve the quality of published veterinary research. The aims of this study were to assess the knowledge and views of veterinary Editors-in-Chief on reporting guidelines, identify the policies of their journals, and determine their information needs. Editors-in-Chief of 185 journals on the contact list for the International Association of Veterinary Editors (IAVE) were surveyed in April 2012 using an online questionnaire which contained both closed and open questions. Results The response rate was 36.8% (68/185). Thirty-six of 68 editors (52.9%) stated they knew what a reporting guideline was before receiving the questionnaire. Editors said they had found out about reporting guidelines primarily through articles in other journals, via the Internet and through their own journal. Twenty of 57 respondents (35.1%) said their journal referred to reporting guidelines in its instructions to authors. CONSORT, REFLECT, and ARRIVE were the most frequently cited. Forty-four of 68 respondents (68.2%) believed that reporting guidelines should be adopted by all refereed veterinary journals. Qualitative analysis of the open questions revealed that lack of knowledge, fear, resistance to change, and difficulty in implementation were perceived as barriers to the adoption of reporting guidelines by journals. Editors suggested that reporting guidelines be promoted through communication and education of the veterinary community, with roles for the IAVE and universities. Many respondents believed a consensus policy on guideline implementation was needed for veterinary journals. Conclusions Further communication and education about reporting guidelines for editors, authors and reviewers has the potential to increase their adoption by veterinary journals in the future.
