Selected AbstractsPostcementation hypersensitivity: Scientific data versus dentists' perceptionsJOURNAL OF PROSTHODONTICS, Issue 2 2003Stephen F. Rosenstiel BDS Purpose The purpose of this article was to obtain dentists' opinions via an Internet survey as to the prevalence, causes, and prevention of postcementation sensitivity and compare their responses with published data on the problem. Materials and Methods Information as to respondents opinions of postcementation sensitivity was obtained from an Internet survey asking about their experience and for a ranking of the importance of each of 15 factors. Results A total of 466 valid responses were received. The incidence of postcementation sensitivity was estimated to be less than 2% by more than 2/3 of the dentists. The factors considered "very important" in reducing sensitivity by more than 50% of the respondents were desiccation, luting agent, occlusion, provisional, and water spray. Conclusions Comparing respondents' opinions with published clinical studies, the incidence of postcementation sensitivity appears to be underestimated. There is little published evidence to support the importance of antimicrobials, desensitizing, or bonding agents, although these are considered effective by some dentists. Many respondents consider luting agent to be an important variable. [source] Intradiscal Electrothermal Coagulation and Percutaneous Neuromodulation Therapy in the Treatment of Discogenic Low Back PainPAIN PRACTICE, Issue 3 2005Dima Rozen MD Abstract: Low back pain (LBP) is a major physical and socioeconomic entity. A significant percentage of LBP is attributable to internal disc disruption. The management of internal disc disruption has traditionally been limited to either conservative treatment or spinal fusion. Intradiscal electrothermal coagulation (IDET) and percutaneous neuromodulation therapy (PNT) are now being performed as an alternative to these therapies. Scientific data regarding the pathophysiology, biologic effects, and clinical results are relatively scarce. Early biomechanical and histologic investigations into the effects of IDET are conflicting. However, in early prospective human trials, IDET seems to provide some benefit with little risk. PNT represents a new less invasive technique for the treatment of discogenic pain, but limited research is available to determine long-term clinical efficacy. IDET and PNT are potentially beneficial treatments for internal disc disruption in carefully selected patients as an alternative to spinal fusion. More basic science and clinical research with long-term follow-up evaluation is necessary. [source] MULTIDISCIPLINARY PAIN ABSTRACTS: 39PAIN PRACTICE, Issue 1 2004Article first published online: 15 MAR 200 A literature review was conducted to review the anatomy, pathophysiology, diagnosis, procedure, and clinical results of intradiscal electrothermal therapy (IDET). Low back pain is a major physical and socioeconomic entity. A significant percentage of low back pain is attributable to internal disc disruption. The management of internal disc disruption has traditionally been limited to either conservative treatment or spinal fusion. IDET has been performed as an alternative to these therapies. The available literature was reviewed. Scientific data regarding the pathophysiology, biologic effects, and clinical results are relatively scarce. Early biomechanical and histologic investigations into the effects of IDET are conflicting. However, in early prospective human trials, IDET seems to provide some benefit with little risk. It was concluded that IDET is a potentially beneficial treatment for internal disc disruption in carefully selected patients as an alternative to spinal fusion. More basic science and clinical research with long-term follow-up evaluation is necessary. [source] Neuroscience instrumentation and distributed analysis of brain activity data: a case for eScience on global GridsCONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 15 2005Rajkumar Buyya Abstract The distribution of knowledge (by scientists) and data sources (advanced scientific instruments), and the need for large-scale computational resources for analyzing massive scientific data are two major problems commonly observed in scientific disciplines. Two popular scientific disciplines of this nature are brain science and high-energy physics. The analysis of brain-activity data gathered from the MEG (magnetoencephalography) instrument is an important research topic in medical science since it helps doctors in identifying symptoms of diseases. The data needs to be analyzed exhaustively to efficiently diagnose and analyze brain functions and requires access to large-scale computational resources. The potential platform for solving such resource intensive applications is the Grid. This paper presents the design and development of MEG data analysis system by leveraging Grid technologies, primarily Nimrod-G, Gridbus, and Globus. It describes the composition of the neuroscience (brain-activity analysis) application as parameter-sweep application and its on-demand deployment on global Grids for distributed execution. The results of economic-based scheduling of analysis jobs for three different optimizations scenarios on the world-wide Grid testbed resources are presented along with their graphical visualization.

Bolick Liquid based Pap (LBP) specimen adequacy is a highly documented, yet poorly understood cornerstone of our GYN cytology practice. Each day, as cytology professionals, we make adequacy assessments and seldom wonder how the criteria we use were established. Are the criteria appropriate? Are they safe? What is the scientific data that support them? Were they clinically and statistically tested or refined to achieve optimal patient care? In this presentation, we will take a fresh look at what we know about Pap specimen adequacy and challenge some of the core assumptions of our daily practice. LBP tests have a consistent, well-defined surface area for screening, facilitating the quantitative estimates of slide cellularity. This provides an unprecedented opportunity to establish reproducible adequacy standards that can be subjected to scientific scrutiny and rigorous statistical analysis. Capitalizing on this opportunity, the TBS2001 took the landmark step to define specimen adequacy quantitatively, and set the threshold for a satisfactory LBP at greater than 5,000 well visualized squamous epithelial cells. To date, few published studies have attempted to evaluate the validity or receiver operator characteristics for this threshold, define an optimal threshold for clinical utility or assess risks of detection failure in ,satisfactory' but relatively hypocellular Pap specimens. Five years of cumulative adequacy and cellularity data of prospectively collected Pap samples from the author's laboratory will be presented, which will serve as a foundation for a discussion on ,Pap failure'. A relationship between cellularity and detection of HSIL will be presented. Risk levels for Pap failure will be presented for Pap samples of different cellularities. The effect of different cellularity criterion on unsatisfactory Pap rates and Pap failure rates will be demonstrated. Results from this data set raise serious questions as to the safety of current TBS2001 adequacy guidelines and suggest that the risk of Pap failure in specimens with 5,000 to 20 000 squamous cells on the slide is significantly higher than those assumed by the current criteria. TBS2001 designated all LBP to have the same adequacy criterion. Up to this point, it has been assumed that ThinPrep, SurePath, or any other LBP would be sufficiently similar that they should have the same adequacy criteria. Data for squamous cellularity and other performance characteristics of ThinPrep and SurePath from the author's laboratory will be compared. Intriguing data involving the recently approved MonoPrep Pap Test will be reviewed. MonoPrep clinical trial data show the unexpected finding of a strong correlation between abundance of endocervical component and the detection of high-grade lesions, provoking an inquiry of a potential new role for a quantitative assessment of the transition zone component. The current science of LBP adequacy criteria is underdeveloped and does not appear to be founded on statistically valid methods. This condition calls us forward as a body of practitioners and scientists to rigorously explore, clarify and define the fundamental nature of cytology adequacy. As we forge this emerging science, we will improve diagnostic performance, guide the development of future technologies, and better serve the patients who give us their trust.

[source] Phytosanitary measures in the European Union: a call for more dynamic risk management allowing more focus on real pest risks Case study: Potato spindle tuber viroid (PSTVd) on ornamental Solanaceae in EuropeEPPO BULLETIN, Issue 3 2008M. B. De Hoop After fifteen years of harmonisation of phytosanitary measures in the European Union, today's legislation has become increasingly stagnant, complex and detailed. The recent finding of Potato spindle tuber viroid in ornamental plants in the Netherlands and other Member States illustrates the struggle to take prompt emergency measures when specific knowledge is not available. It is proposed that the European Commission should take the initiative to organise the process of pest risk analysis from beginning to end. In addition, the Commission should have budgets at their disposal for instantaneous research to generate the required data and fill in knowledge gaps. Such policy enables evaluation of emergency measures and implementation of permanent requirements on the basis of scientific data within a short period, thereby creating a dynamic legislation that focuses on real pest risks. [source] Quantification by real-time PCR of the magnitude and duration of leucocyte-associated viraemia in horses infected with neuropathogenic vs. non-neuropathogenic strains of EHV- 1EQUINE VETERINARY JOURNAL, Issue 3 2006G. P. Allen Summary Reasons for performing study: Neurological disease in horses caused by infection with certain ,paralytic' strains of equine herpesvirus-1 (EHV-1) is a potentially devastating condition the pathogenesis of which is poorly understood. Preliminary observations in both experimentally induced and naturally occurring cases of the central nervous system disease have revealed a more robust cell-associated viraemia in horses infected with paralytic isolates of EHV-1, relative to horses infected with abortigenic isolates. To investigate further this pathogenesis - rdevant question, the present study was performed using a greater number of horses and a more precise method for quantification of EHV-1 DNA present in viraemic leucocytes. Objective: To compare the magnitude and duration of leucocyte-associated viraemia in seronegative, age-matched foals following infection with paralytic vs. abortigenic isolates of EHV-1. Methods: Peripheral blood mononuclear cells (PBMC) were collected from 20 weanling foals at 2, 4, 7, 9, 11, 14 and 21 days after intranasal inoculation with either paralytic or abortigenic isolates of EHV-1. The amount of EHV-1 DNA present in each PBMC sample was measured by real-time quantitative PCR. Results: Foals inoculated with paralytic strains of EHV-1 developed both a greater magnitude and longer duration of PBMC-associated viraemia than foals inoculated with abortigenic strains of the virus. Conclusions: Both the higher magnitude and longer duration of cell-associated viraemia contribute to the risk for development of neurological signs in horses infected with paralytic strains of EHV-1. Potential relevance: Our results provide empirically derived, scientific data that contributes to a better understanding of the pathogenetic basis for the differing abilities of paralytic and abortigenic strains of EHV-1 to cause post infection central nervous system disease in the horse. The findings identify the importance of minimising the quantitative burden of viraemic leucocytes that follows exposure to the virus, by the use of effective therapeutic antiviral drugs and efficacious prophylactic vaccines that stimulate cytotoxic immune responses against EHV-1 infected cells.

SHURPALI Abstract Marginal organic soils, abundant in the boreal region, are being increasingly used for bioenergy crop cultivation. Using long-term field experimental data on greenhouse gas (GHG) balance from a perennial bioenergy crop [reed canary grass (RCG), Phalaris arundinaceae L.] cultivated on a drained organic soil as an example, we show here for the first time that, with a proper cultivation and land-use practice, environmentally sound bioenergy production is possible on these problematic soil types. We performed a life cycle assessment (LCA) for RCG on this organic soil. We found that, on an average, this system produces 40% less CO2 -equivalents per MWh of energy in comparison with a conventional energy source such as coal. Climatic conditions regulating the RCG carbon exchange processes have a high impact on the benefits from this bioenergy production system. Under appropriate hydrological conditions, this system can even be carbon-negative. An LCA sensitivity analysis revealed that net ecosystem CO2 exchange and crop yield are the major LCA components, while non-CO2 GHG emissions and costs associated with crop production are the minor ones. Net bioenergy GHG emissions resulting from restricted net CO2 uptake and low crop yields, due to climatic and moisture stress during dry years, were comparable with coal emissions. However, net bioenergy emissions during wet years with high net uptake and crop yield were only a third of the coal emissions. As long-term experimental data on GHG balance of bioenergy production are scarce, scientific data stemming from field experiments are needed in shaping renewable energy source policies. [source] Isotretinoin and the controversy of psychiatric adverse effectsINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 7 2006Jamison E. Strahan MD Isotretinoin is a synthetic oral retinoid that has great efficacy against severe, recalcitrant, nodulocystic acne. Since its introduction to the market, it has been associated with a variety of adverse psychiatric effects, including depression, psychosis, mood swings, violent behavior, suicide, and suicide attempts. A MEDLINE review was performed to compile all case reports, case series, adverse drug event reportings, and prospective and retrospective studies relating psychiatric adverse events to isotretinoin. In addition, literature linking a biological mechanism for psychiatric adverse events to retinoid signaling pathways was also reviewed. Although a variety of anecdotal and epidemiologic studies are available, the overall lack of concrete scientific data limits any conclusion that can be drawn about a causal relationship between istotretinoin and psychiatric adverse events. Several lines of evidence link retinoid signaling to theorized psychiatric pathogenesis, but are limited in their applicability to adult neurophysiology. [source] Improving geriatric mental health nursing care: Making a case for going beyond psychotropic medicationsINTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 1 2003Philippe Voyer ABSTRACT Providing high-quality mental health nursing care should be an important and continuous preoccupation in the gerontological nursing field. As the proportion of elderly people in our society is growing, the emphasis on high-quality care will receive increasing attention from administrators, politicians, organized groups, researchers and clinical nurses. Recent findings illustrate unequivocally the important contribution of nurses to achieving the goal of high-quality geriatric care. However, the quality of care for the elderly with psychological difficulties has not been addressed. The objective of this article is to illustrate that while nurses can accomplish much to improve the well-being and mental health of the elderly, their skills are often underutilized. Psychotropic drugs are often the first-line interventions used by health-care professionals to treat mental health concerns of elderly persons. Alternative therapies that could be implemented and evaluated, such as psychological counselling, supportive counselling, education and life review, are infrequently used. Nevertheless, current scientific data suggest that it would be very advantageous if nurses were to play a dominant role in the care of elderly people who are depressed or experiencing sleep pattern disturbances. The same can be said about elderly chronic users of benzodiazepines, as well as those with cognitive impairment. Evidence for the use of psychotropic medications as a viable treatment option for the elderly both in the community and in the long-term care setting who are experiencing mental health challenges is examined. Alternative non-pharmacological approaches that nurses can use to augment care are also briefly discussed. [source] Data collection from the Antarctic region through a W-band low Earth orbit satelliteINTERNATIONAL JOURNAL OF SATELLITE COMMUNICATIONS AND NETWORKING, Issue 4 2001Marina Ruggieri Abstract The DAVID (DAta and Video Interactive Distribution) mission is being carried out in the framework of the Science Small Missions Program of the Italian Space Agency. The mission is aimed at the deployment of two scientific telecommunication experiments through a low Earth orbit (LEO) satellite. The paper will focus on one of these experiments, that will test a satellite system architecture for the exchange of a large amount of data and high definition images through a W-band link and a Ka-band inter-satellite link between the LEO and the ARTEMIS satellite. The proposed architecture, that will explore various innovative aspects, will also allow for the first time the distribution of large volumes of scientific data collected from the Antarctic region and other extremely remote areas of the Earth. The availability of a return link in the envisaged system will also allow interactive control of the various laboratories located in the remote sites. Copyright © 2001 John Wiley & Sons, Ltd.

Peer-reviewed scientific data for intense pulsed light systems are lacking. Objective, A chronicle of three patients who have participated in the treatment of inflamed, hypertrophic, and colloidal scars, using intense pulsed light. Methods, Intense pulsed light with a selection of wavelengths, pulse durations, and energy densities was used on patients with inflamed, hypertrophic, and colloidal scars. Results, A definite improvement in scar tissue was observed and achieved in all the cases. Conclusion, Intense pulsed light source with the correct outputs is an effective tool for the treatment and improvement of inflamed, hypertrophic, and colloidal scars. [source] Herpetic Cytopathic Features Confined to Folliculosebaceous Units: What does it Mean?JOURNAL OF CUTANEOUS PATHOLOGY, Issue 1 2005N Walsh The histopathological changes of herpes simplex, zoster and varicella are considered to be indistinguishable from one another. The clinical setting with adjunctive studies generally clarifies the diagnosis. Vesicular lesions in all 3 conditions can involve epidermal and adnexal epithelium with characteristic cytopathic features. We describe 3 patients with non-vesicular eruptions on the head and neck whose biopsies revealed exclusive folliculosebaceous involvement by herpes. All three patients developed typical herpes zoster within days of the biopsy. There is compelling scientific evidence in the literature indicating that, in herpes zoster, the virus is transported from dorsal root or trigeminal ganglia via myelinated nerves to the skin. These terminate at the isthmus of hair follicles and primary infection of follicular and sebaceous epithelium occurs. Secondary spread of infection to the epidermis follows. In contrast, data pertaining to recurrent herpes simplex indicates that axonal transport of the virus from sensory ganglia to the skin is directed primarily to the epidermis, via terminal non-myelinated nerve twigs. The clinical evolution of our 3 cases and scientific data in the literature indicate that exclusive folliculosebaceous involvement by herpes, in the setting of a non-vesicular eruption, represents early herpes zoster. [source] NOVEL NONTHERMAL METHODS TO REDUCE VIBRIO VULNIFICUS IN RAW OYSTERSJOURNAL OF FOOD SAFETY, Issue 3 2003ABDOLSAMAD BORAZJANI ABSTRACT Vibrio vulnificus is a foodborne pathogen associated with consumption of raw oyster. No scientific data is available on postharvest treatments of oyster by ultrasound, ozone, and organic acids. This study was designed to investigate the effects of these treatments on inactivation of V. vulnificus naturally present in the in-shell or half-shelled oysters. In in-shell oysters, these treatments were not effective in reducing the number of this pathogen. Half-shelled oysters treated with ultrasound, and ozone in 2% saline for 30 min had 1 and 1.5 log less V. vulnificus, respectively (p<0.05). Treatment of half-shelled oysters by 50 and 100% lemon juice, 5% citric acid, 10% citric acid, or vinegar for 30 min resulted in a significant reduction (2,4 log) in the numbers of V. vulnificus (p<0.05). Although these methods significantly reduced the population of V. vulnificus in raw oysters, they were not able to reduce the numbers of this pathogen to acceptable level (<3 MPN/g).

It is shown that the red, yellow and black samples are cinnabar, PbSO4,PbO and carbon black, respectively, and well preserved, which provide scientific data for later conservation. Moreover, the results indicate that HREM and Raman analysis are very effective for identifying ancient inorganic pigments at low concentrations. Copyright © 2004 John Wiley & Sons, Ltd. [source] Review article: complementary and alternative therapies for inflammatory bowel diseaseALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 3 2006L. LANGMEAD Summary Complementary and alternative medicine includes a wide range of practices and therapies outside the realms of conventional western medicine. Despite a lack of scientific data in the form of controlled trials for either efficacy or safety of complementary and alternative medicine, use by patients with inflammatory bowel disease, particularly of herbal therapies, is widespread and increasing. There is limited controlled evidence indicating efficacy of traditional Chinese medicines, aloe vera gel, wheat grass juice, Boswellia serrata and bovine colostrum enemas in ulcerative colitis. Encouraging results have also been reported in small studies of acupuncture for Crohn's disease and ulcerative colitis. Contrary to popular belief, natural therapies are not necessarily safe: fatal hepatic and irreversible renal failure have occurred with some preparations and interactions with conventional drugs are potentially dangerous. There is a need for further controlled clinical trials of the potential efficacy of complementary and alternative approaches in inflammatory bowel disease, together with enhanced legislation to maximize their quality and safety. [source] The impact of human herpesvirus-6 and -7 infection on the outcome of liver transplantationLIVER TRANSPLANTATION, Issue 8 2002Raymund R. Razonable Human herpesvirus (HHV)-6 and -7 are novel members of the ,-herpesvirus family that maintain latency in the human host after primary infection. Reactivation from latency and/or increased degree of viral replication occurs during periods of immune dysfunction. The clinical effect of HHV-6 and HHV-7 reactivation in recipients of liver transplants is now being recognized. Clinical illnesses such as fever, rash, pneumonitis, encephalitis, hepatitis, and myelosuppression have been described in a number of anecdotal reports. Moreover, a growing body of evidence suggests that the more important effect of HHV-6 and HHV-7 reactivation on the outcomes of liver transplantation may be mediated indirectly by their interactions with the other ,-herpesvirus,cytomegalovirus (CMV). Coinfection among these three ,-herpesviruses in clinical syndromes that were classically ascribed to be solely caused by CMV has been shown and has raised substantial interest in the potential role of HHV-6 and HHV-7 as copathogens in the direct and indirect illnesses caused by CMV. This article reviews the current scientific data on the role and the magnitude of impact of HHV-6 and HHV-7 infection on the outcomes of liver transplantation. [source] Use and practice of patient diaries in Swedish intensive care units: a national surveyNURSING IN CRITICAL CARE, Issue 1 2010Eva Åkerman Aims and objectives: To describe and compare the extent and application of patients' diaries in Sweden. Background: Since 1991, patient diaries have been used in intensive care unit (ICU) follow-up in Sweden. There is paucity of relevant data evaluating the effect of this tool and also on what premises patients are enrolled. Likewise, data are sparse on the diaries' design, content structure and the use of photographs. Design: Descriptive explorative design by a semi-structured telephone interview. Methods: The interview results were analysed with descriptive statistics and differences between the ICU levels were explored by ,2 analysis. Qualitative manifest content analysis was performed to explore the purpose of diary writing. Results: Of all ICUs (n = 85), 99% responded and 75% used diaries. The source of inspiration was collegial rather than from scientific data. The main reason for keeping a diary was to help the patient to recapitulate the ICU stay. Discrepancies between the different levels of ICUs were detected in patient selection, dedicated staff for follow-up and the use of photographs. Comparison between the ,2 analysis and the content analysis outcome displayed incongruence between the set unit-goals and the activities for achievement but did not explain the procedural differences detected. Conclusion: The uses of diaries in post ICU follow up were found to be common in Sweden. A majority used defined goals and content structure. However, there were differences in practice and patient recruitment among the levels of ICUs. These discrepancies seemed not to be based on evidence-based data nor on ongoing research or evaluation but merely on professional judgement. As ICU follow-up is resource intense and time consuming, it is paramount that solid criteria for patient selection and guidelines for the structure and use of diaries in post-ICU follow-up are defined.

Method , Major trends in information technology determine the progress made in craniofacial imaging and informatics. These trends include industry consolidation, disruptive technologies, Moore's law, electronic atlases and on-line databases. Each of these trends is explained and documented, relative to their influence on craniofacial imaging. Results , Craniofacial imaging is influenced by major trends that affect all medical imaging and related informatics applications. The introduction of cone beam craniofacial computed tomography scanners is an example of a disruptive technology entering the field. An important opportunity lies in the integration of biologic knowledge repositories with craniofacial images. Conclusion , The progress of craniofacial imaging will continue subject to limitations imposed by the underlying technologies, especially imaging informatics. Disruptive technologies will play a major role in the evolution of this field. [source] Associations Between Coerced Anal Sex and Psychopathology, Marital Distress and Non-Sexual ViolenceTHE JOURNAL OF SEXUAL MEDICINE, Issue 7 2009Parvaneh Mohammadkhani PhD ABSTRACT Background., There is a dearth of scientific data on anal intercourse in heterosexual relationships. Likewise, anal sex within marital relationships has yet to be fully explored. Objectives., Among a representative sample of married women in the Iranian capital, Tehran, we aimed to determine the association of self-reported coerced anal sex with: (i) self-reported coerced vaginal sex; (ii) self-reported non-sexual violence; (iii) psychopathology; and (iv) marital attitude. Method., The data presented here were obtained from the Family Violence Survey conducted in Tehran in 2007. A total of 230 married Iranian women were selected via a multi-cluster sampling method from four different randomized regions. The subjects' sociodemographic data, psychological distress (Symptom Check List; SCL-90-R), personality, and relationship characteristics (Personal and Relationships Profile), and marital attitude (Marital Attitude Survey) were gathered. In addition, the participants' self-reported histories of lifetime victimization through all types of violence by the husband, including coerced anal and vaginal sex as well as psychological and physical assault (Conflict Tactic Scales-Revised; CTS-2), were collected. Results., There were associations between self-reported victimization through coerced anal and vaginal sex (P < 0.001), psychological (P < 0.001), and physical aggression (P < 0.001). Those reporting to have been forced into anal intercourse cited higher rates of paranoid and psychotic features, jealousy, attribution of problems to one's own behavior, conflict, and male dominance, as well as lower expectations of improvement in one's marital relationship. Conclusion., In marital relationships, women are at a higher risk of coerced anal sex if subjected to other types of sexual or non-sexual violence. Higher rates of psychopathology and poorer marital relationships are also allied to self-reported anal sexual coercion.

Hanafy MD ABSTRACT Introduction., With the recent increased recognition and treatment of hypogonadism in men, a caution has been given that testosterone replacement therapy (TRT) may cause or aggravate obstructive sleep apnea syndrome (OSA). Aim., To evaluate the scientific data behind the cautionary statements about TRT and OSA. Main Outcome Measures., Methodology and criteria for such studies and evaluation of documents and results based on methodology, duration, and outcome of treatment. Methods., A review of the literature on the subject of TRT and OSA was performed. The possible mechanisms of action of TRT, on breathing and respiration during sleep were explored. Result., Historically, the first such caution came in 1978. Since then, a few similar incidence reports have been cited. The total number of patients in such reports was very small, very disproportional to the millions of patients treated with TRT. Also, there was a lack of consistent findings connecting TRT to OSA. In addition, different results may occur with physiologic replacement vs. supraphysiologic doses in regard to breathing and OSA. The studies showing the effect of TRT on OSA and breathing were all case studies with small numbers of subjects and showed little effect of TRT on OSA in the majority of case reports. Only one study using supraphysiologic doses was a double-blind, placebo-controlled study, which showed a development of OSA in healthy pooled subjects. The other reports were case studies with limited numbers of subjects, suggesting an inconsistent effect of supraphysiologic TRT on OSA and breathing. Conclusion., Cautionary statements about TRT in OSA appear frequently in the TRT literature and guidelines, despite lack of convincing evidence that TRT causes and/or aggravates OSA. Also, there is a lack of consistency in the findings connecting TRT to OSA. It is evident that the link between TRT and OSA is weak, based on methodological issues in many of the studies, and most studies involved small numbers of men. Further studies in this area are needed. Hanafy HM. Testosterone therapy and obstructive sleep apnea: Is there a real connection? J Sex Med 2007;4;1241,1246. [source] Assessing ecological changes in and around marine reserves using community perceptions and biological surveysAQUATIC CONSERVATION: MARINE AND FRESHWATER ECOSYSTEMS, Issue 4 2010M. Yasué Abstract 1. Well-enforced partial or total no-fishing zones (collectively known as marine protected areas, or MPAs) can help restore degraded coral reefs and enhance fish populations. 2. A comparison was made of community perceptions of ecological changes in an MPA with concurrent scientific data on these changes in the same MPA. Such analyses are particularly important in community-based MPAs where local support is a key determinant of ecological success. 3. The no-take MPA in question was initially launched in partnership with the community in 1995 and formalized in 1998. The perceptions data come from interviews with community members in 1999 and 2004, the biological data come from underwater visual censuses of the MPA from 1998 to 2004. 4. Community members perceived more fish within the MPA and slight increases in catch outside the MPA. In contrast, fish censuses showed a high degree of stochastic variation and only minor increases in fish abundance, size and diversity in and around the MPA between 1998 and 2004. 5. Possible explanations for these discrepancies include different temporal, spatial or species frames of reference and/or limitations to the biological survey technique. Other options include wishful thinking, external influences, a desire to please, or confounding with other benefits. 6. This study demonstrates some of the strengths and weaknesses of community perceptions and biological data. In order to improve our understanding about the changes that occur over time in an MPA and engender community support for the long-term viability of MPAs, it is important to develop diverse and efficient monitoring schemes.

Keith Abstract 1.In 1995, the IUCN implemented new definitions to be used when drawing up red lists. However, in addition to being imprecise for fish species, these remain difficult to apply. 2.This paper describes a more exhaustive method under the IUCN (1995) definitions based on six quantitative and qualitative criteria where scientific data are given the greatest possible weight, as compared with ,expert opinion'. This dual system makes it possible both to allocate an IUCN category to each species, and to rank each species within a particular category according to given scores, so that priorities can be determined. 3.The new Red List for French Freshwater Fish drawn up with this method contains 27 species, or 54% of the French native fauna. Three species are extinct (EX), four are critically endangered (CR), two are endangered (EN), 14 are vulnerable (VU), and four are at lower risk (LR). 4.Based on sounder scientific grounds, this list modifies and replaces the one drawn up in 1992. In effect, it makes it easier to argue for the presence of one species in one category rather than in another. Copyright © 2002 John Wiley & Sons, Ltd. [source] Smoking and periodontal diseaseAUSTRALIAN DENTAL JOURNAL, Issue 2009K-Y Zee Abstract Periodontal disease is considered to be an opportunistic infection as a result of interactions between the causative agents (dental plaque) and the host responses which may be modulated by genetic, environmental and acquired risk factors. Besides being a well-confirmed risk factor in a number of systemic diseases, tobacco smoking has also been associated with periodontal disease. Over the past 10,15 years, more and more scientific data on the impact of smoking on various aspects of periodontal disease and the underlying mechanisms has been published. The purpose of this review was to provide an overview of the available data in order to give practitioners a better understanding of the relationship between smoking and periodontal disease. Subsequently, they can use some of the information in treatment decisions and give advice to patients who are smokers suffering from periodontal disease. [source] | |||||||||||||||||||
