    The development and validation of a new coeliac disease quality of life survey (CD-QOL)

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 6 2010
    S. D. DORN
    Aliment Pharmacol Ther,31, 666,675 Summary Background, Previous studies on coeliac disease (CD)-related quality of life (QOL) have been limited by their use of a ,generic' rather than coeliac disease-specific assessment instruments. Aim, To develop and psychometrically validate a new coeliac disease-specific instrument, the CD-QOL. Methods, Through a series of focus groups, we elicited items from patients that related to the specific nature of their disease and its impact on their basic needs. Through expert review, cognitive debriefing with patients and pilot testing, a scale was developed, refined and administered to 387 patients on a gluten-free diet from both community-based support groups and a tertiary care referral centre. Finally, a formal validation study was conducted to assess the psychometric properties of the CD-QOL. Results, The final CD-QOL has 20 items across four clinically relevant subscales (Limitations, Dysphoria, Health Concerns, and Inadequate Treatment). The CD-QOL has high internal consistency, reliability, and psychometric validation indicates both convergent and discriminate validity. Conclusions, The CD-QOL is a reliable and valid measure of coeliac disease related QOL. As a new disease-specific instrument, it is likely to be a useful tool for evaluating patients with this disorder. [source]

    Tanning and Cutaneous Malignancy

    DERMATOLOGIC SURGERY, Issue 4 2008
    SHERRIF F. IBRAHIM MD
    BACKGROUND Exposure to ultraviolet radiation (UVR) results in a darkening of the skin known as tanning. Recently, it has been shown that tanning is a response to UVR-induced DNA damage and represents the skin's efforts to protect itself against further injury. Despite the link between UVR and cutaneous malignancy, people continue to pursue tanning from natural and artificial sources. This trend is reflected in the exponential rise in skin cancer incidence. OBJECTIVE The objective of this study was to review our current understanding of the factors controlling the tanning response and the relationship to cutaneous carcinogenesis, as well as the impact that the multibillion dollar tanning industry has had on the practice of dermatology. MATERIALS AND METHODS Extensive literature review was conducted in subjects related to tanning and the relationship to cutaneous malignancy. RESULTS Our knowledge of tanning and its effects on the skin has increased tremendously. It is clear that tanning contributes to the development of skin cancer. Despite this information, the incidence of skin cancer continues to increase exponentially. CONCLUSIONS Skin cancer poses a major public health concern and tanning remains the most modifiable risk factor in its etiology. Social, economic, and legislative issues have become tightly intertwined with the complex nature of human behavior in the continued pursuit of an activity that clearly has detrimental effects on one's health.

    Inadequacies of absolute threshold levels for diagnosing prediabetes

    DIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue 1 2010
    Michael Bergman
    Abstract Prediabetes comprising Impaired Fasting Glucose (IFG) and Impaired Glucose Tolerance (IGT) represents an intermediate stage of altered glucose metabolism between normal glucose levels and type 2 diabetes mellitus and is associated with an increased risk for the development of diabetes and cardiovascular disease. There is considerable evidence that glucose levels lower than those meeting the current definition of prediabetes may also be associated with similar risks particularly in high-risk individuals. Prediabetes is often unrecognized and therefore constitutes a major public health concern suggesting the need for earlier intervention than is currently recommended.

    Human papillomavirus prevalence and cytopathology correlation in young Ugandan women using a low-cost liquid-based pap preparation

    DIAGNOSTIC CYTOPATHOLOGY, Issue 8 2010
    Janis M. Taube M.D.
    Abstract Screening for HPV-driven cervical dysplasia and neoplasia is a significant public health concern in the developing world. The purpose of this study was to use a manual, low-cost liquid-based Pap preparation to determine HPV prevalence in HIV-positive and HIV-negative young women in Kampala, Uganda and to correlate cervical cytopathology with HPV-DNA genotype. About 196 post-partum women aged 18,30 years underwent rapid HIV testing and pelvic examination. Liquid-based cervical cytology samples were processed using a low-cost manual technique. A DNA collection device was used to collect specimens for HPV genotyping. HIV and HPV prevalence was 18 and 64%, respectively. Overall, 49% of women were infected with a high-risk HPV genotype. The most common high-risk HPV genotypes were 16 (8.2%), 33 (7.7%), 35 (6.6%), 45 (5.1%), and 58 (5.1%). The prevalence of HPV 18 was 3.6%. HIV-positive women had an HPV prevalence of 86% compared to 59% in HIV-negative women (P = 0.003). The prevalence of HPV 16/18 did not differ by HIV status. HIV-positive women were infected with a significantly greater number of HPV genotypes compared to HIV-negative women. By multivariate analysis, the main risk factor for HPV infection was coinfection with HIV. HIV-positive women were four times more likely to have abnormal cytology than HIV-negative women (43% vs. 11.6%, P < 0.001). These data highlight that HIV infection is a strong risk factor for HPV infection and resultant abnormal cervical cytology. Notably, the manual low-cost liquid-based Pap preparation is practical in this setting and offers an alternate method for local studies of HPV vaccine efficacy. Diagn.

    Health outcomes associated with methamphetamine use among young people: a systematic review

    ADDICTION, Issue 6 2010
    Brandon D. L. Marshall
    ABSTRACT Objectives Methamphetamine (MA) use among young people is of significant social, economic and public health concern to affected communities and policy makers. While responses have focused upon various perceived severe harms of MA use, effective public health interventions require a strong scientific evidence base. Methods We conducted a systematic review to identify scientific studies investigating health outcomes associated with MA use among young people aged 10,24 years. The International Classification of Diseases (ICD-10) was used to categorize outcomes and determine the level of evidence for each series of harms. Results We identified 47 eligible studies for review. Consistent associations were observed between MA use and several mental health outcomes, including depression, suicidal ideation and psychosis. Suicide and overdose appear to be significant sources of morbidity and mortality among young MA users. Evidence for a strong association between MA use and increased risk of human immunodeficiency virus (HIV) and other sexually transmitted infections is equivocal. Finally, we identified only weak evidence of an association between MA use and dental diseases among young people. Conclusions Available evidence indicates a consistent relationship between MA use and mental health outcomes (e.g. depression, psychosis) and an increased risk of mortality due to suicide and overdose. We found insufficient evidence of an association between MA use and other previously cited harms, including infectious diseases and dental outcomes. As such, future research of higher methodological quality is required to further investigate possible associations. Current interventions should focus attention upon MA-related health outcomes for which sound scientific evidence is available. [source]


    Ambient temperature and risk of death from accidental drug overdose in New York City, 1990,2006

    ADDICTION, Issue 6 2010
    Amy S. B. Bohnert
    ABSTRACT Background Mortality increases as ambient temperature increases. Because cocaine affects core body temperature, ambient temperature may play a role in cocaine-related mortality in particular. The present study examined the association between ambient temperature and fatal overdoses over time in New York City. Methods Mortality data were obtained from the Office of the Chief Medical Examiner for 1990 to 2006, and temperature data from the National Oceanic and Atmospheric Association. We used generalized additive models to test the relationship between weekly average temperatures and counts of accidental overdose deaths in New York City, controlling for year and average length of daylight hours. Results We found a significant relation between ambient temperature and accidental overdose fatality for all models where the overdoses were due in whole or in part to cocaine (all P < 0.05), but not for non-cocaine overdoses. Risk of accidental overdose deaths increased for weeks when the average temperature was above 24°Celsius. Conclusions These results suggest a strong relation between temperature and accidental overdose mortality that is driven by cocaine-related overdoses rising at temperatures above 24°Celsius; this is a substantially lower temperature than prior estimates. To put this into perspective, approximately 7 weeks a year between 1990 and 2006 had an average weekly temperature of 24 or above in New York City. Heat-related mortality presents a considerable public health concern, and cocaine users constitute a high-risk group. [source]


    Mephentermine dependence without psychosis: a Brazilian case report

    ADDICTION, Issue 6 2010
    Henrique Faria De Sousa
    ABSTRACT Background Substance abuse is a serious health concern. This report presents the case of a 22-year-old Brazilian man with a history of mephentermine use who fulfils all the criteria for chemical dependence listed by ICD-10. Mephentermine is a sympathomimetic agent derived from methamphetamine which, in Brazil, is restricted to veterinary use. Case description The subject used the substance at a high dose (120 mg) to improve his physical performance while working out at a gym. His symptoms included anorexia and insomnia. After days of intense activity, he felt fatigue and soreness. A physical examination revealed scars on both forearms from the injections and a psychological examination revealed moderate speech and motor agitation. Conclusions Cases such as this may be common among the general public. They should have some bearing upon medical practice and public health policies involving drugs. [source]


    Quantitative microbial faecal source tracking with sampling guided by hydrological catchment dynamics

    ENVIRONMENTAL MICROBIOLOGY, Issue 10 2008
    G. H. Reischer
    Summary The impairment of water quality by faecal pollution is a global public health concern. Microbial source tracking methods help to identify faecal sources but the few recent quantitative microbial source tracking applications disregarded catchment hydrology and pollution dynamics. This quantitative microbial source tracking study, conducted in a large karstic spring catchment potentially influenced by humans and ruminant animals, was based on a tiered sampling approach: a 31-month water quality monitoring (Monitoring) covering seasonal hydrological dynamics and an investigation of flood events (Events) as periods of the strongest pollution. The detection of a ruminant-specific and a human-specific faecal Bacteroidetes marker by quantitative real-time PCR was complemented by standard microbiological and on-line hydrological parameters. Both quantitative microbial source tracking markers were detected in spring water during Monitoring and Events, with preponderance of the ruminant-specific marker. Applying multiparametric analysis of all data allowed linking the ruminant-specific marker to general faecal pollution indicators, especially during Events. Up to 80% of the variation of faecal indicator levels during Events could be explained by ruminant-specific marker levels proving the dominance of ruminant faecal sources in the catchment. Furthermore, soil was ruled out as a source of quantitative microbial source tracking markers. This study demonstrates the applicability of quantitative microbial source tracking methods and highlights the prerequisite of considering hydrological catchment dynamics in source tracking study design.

    Methyl- tert -hexyl ether and methyl- tert -octyl ether as gasoline oxygenates: Anticipating widespread risks to community water supply wells,

    ENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 11 2007
    Jeff Snelling
    Abstract The widespread contamination of groundwater resources associated with methyl- tert -butyl ether (MtBE) use has prompted a search for replacement oxygenates in gasoline. Among the alternatives currently under development are higher methyl- tert -alkyl ethers, notably methyl- tert -hexyl ether (MtHxE) and methyl- tert -octyl ether (MtOcE). As was the case with MtBE, the introduction of these ethers into fuel supplies guarantees their migration into groundwater resources. In the present study, a screening-level risk assessment compared predicted well water concentrations of these ethers to concentrations that might cause adverse effects. A physicochemical model which has been successfully applied to the prediction of MtBE concentrations in community water supply wells (CSWs) was used to predict well water concentrations of MtHxE and MtOcE. The results indicate that these ethers are likely to contaminate water supply wells at slightly lower levels than MtBE as a result of migrating from leaking underground fuel tanks to CSWs. Because very little data is available on the physicochemical and environmental properties of MtHxE and MtOcE, estimation methods were employed in conjunction with the model to predict well water concentrations. Model calculations indicated that MtHxE and MtOcE will be present in many CSWs at concentrations approaching the concentrations that have caused widespread public health concern for MtBE. Based on these results and the possibility that MtHxE and MtOcE are potential carcinogens, testing of the toxicological properties of these ethers is recommended before they are used to replace MtBE in gasoline.

    Seasonality effects on pharmaceuticals and s -triazine herbicides in wastewater effluent and surface water from the Canadian side of the upper Detroit River

    ENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 9 2006
    Wen Yi Hua
    Abstract The influence of seasonal changes in water conditions and parameters on several major pharmacologically active compounds (PhACs) and s -triazine herbicides was assessed in the wastewater and sewage treatment plant (WSTP) effluent as well as the downstream surface water from sites on the Canadian side of the upper Detroit River, between the Little River WSTP and near the water intake of a major drinking water treatment facility for the City of Windsor (ON, Canada). The assessed PhACs were of neutral (carbamazepine, cotinine, caffeine, cyclophosphamide, fluoxetine, norfluoxetine, pentoxifylline, and trimethoprim) and acidic (ibuprofen, bezafibrate, clofibric acid, diclofenac, fenoprofen, gemfibrozil, indomethacin, naproxen, and ketoprofen) varieties. The major assessed s -triazine herbicides were atrazine, simazine, propazine, prometon, ametryn, prometryn, and terbutryn. At sampling times from September 2002 to June 2003, 15 PhACs were detected in the WSTP effluent at concentrations ranging from 1.7 to 1,244 ng/L. The PhAC concentrations decreased by as much 92 to 100% at the Little River/Detroit River confluence because of the river dilution effect, with further continual decreases at sites downstream from the WSTP. The only quantifiable s -triazine in WSTP effluent, atrazine, ranged from 6.7 to 200 ng/L and was higher in Detroit River surface waters than in WSTP effluent. Only carbamazepine, cotinine, and atrazine were detectable at the low-nanogram and subnanogram levels in surface waters near a drinking water intake site. Unlike the PhACs, atrazine in the Detroit River is not attributable to point sources, and it is heavily influenced by seasonal agricultural usage and runoff. Detroit River surface water concentrations of carbamazepine, cotinine, and atrazine may present a health concern to aquatic wildlife and to humans via the consumption of drinking water. [source]


    Bauxite manufacturing residues from Gardanne (France) and Portovesme (Italy) exert different patterns of pollution and toxicity to sea urchin embryos

    ENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 6 2002
    Giovanni Pagano
    Abstract This study was designed to investigate the composition and toxicity of solid residues from bauxite manufacturing plants. Soil and dust samples were collected in the proximity of two bauxite plants (Gardanne, France, and Portovesme, Italy). Samples were analyzed for their content of some selected inorganic contaminants by means of inductively coupled plasma optical emission spectroscopy (ICP-OES) either following acid digestion procedures or by seawater release of soluble components. Toxicity was tested by sea urchin bioassays to evaluate a set of toxicity endpoints including acute embryotoxicity, developmental defects, changes in sperm fertilization success, transmissible damage from sperm to the offspring, and cytogenetic abnormalities. Inorganic analysis showed two distinct sets of inorganic contaminants in Gardanne versus Portovesme, including Al, Cr, Cu, Fe, Mn, Pb, Ti, and Zn; sample composition (seawater-soluble cotaminants) and toxicity showed a noteworthy association. The most severe toxicity to embryogenesis and to sperm fertilization success was exerted by some Portovesme samples (0.03,0.5% w/v), with a significant association between toxicity and dose-related seawater release of Zn, Pb, and Mn. Seawater extraction of a toxic dust sample (G20) from the Gardanne factory showed increasing seawater release of Al, Fe, and Mn; the G20 sample, at the level of 0.5%, affected both developing sea urchin embryos and sperm (offspring quality). Soil samples around the Gardanne factory showed the highest frequency of toxic soil sites eastward from the factory. The present data point to solid deposition from bauxite plants as a potential subject of environmental health concern. The results suggest that extraction methods for evaluating the toxicity of complex mixtures should be based on the environmental availability of mixture components. The differences in sample toxicity among the tested sites, however, suggest possible site-to-site variability in geochemical and/or technological parameters. [source]

    Impaired CD4+ T-cell proliferation and effector function correlates with repressive histone methylation events in a mouse model of severe sepsis

    EUROPEAN JOURNAL OF IMMUNOLOGY, Issue 4 2010
    William F. Carson
    Abstract Immunosuppression following severe sepsis remains a significant human health concern, as long-term morbidity and mortality rates of patients who have recovered from life-threatening septic shock remain poor. Mouse models of severe sepsis indicate this immunosuppression may be partly due to alterations in myeloid cell function; however, the effect of severe sepsis on subsequent CD4+ T-cell responses remains unclear. In the present study, CD4+ T cells from mice subjected to an experimental model of severe sepsis (cecal ligation and puncture (CLP)) were analyzed in vitro. CD4+CD62L+ T cells from CLP mice exhibited reduced proliferative capacity and altered gene expression. Additionally, CD4+CD62L+ T cells from CLP mice exhibit dysregulated cytokine production after in vitro skewing with exogenous cytokines, indicating a decreased capability of these cells to commit to either the TH1 or TH2 lineage. Repressive histone methylation marks were also evident at promoter regions for the TH1 cytokine IFN-, and the TH2 transcription factor GATA-3 in naļve CD4+ T cells from CLP mice. These results provide evidence that CD4+ T-cell subsets from post-septic mice exhibit defects in activation and effector function, possibly due to chromatin remodeling proximal to genes involved in cytokine production or gene transcription.

    Nonalcoholic steatohepatitis and hepatocellular carcinoma in galectin-3 knockout mice

    HEPATOLOGY RESEARCH, Issue 12 2008
    Yuko Nakanishi
    Aim:, Nonalcoholic fatty liver disease (NAFLD) represents a growing health concern due to its rapidly increasing prevalence worldwide. Nonalcoholic steatohepatitis (NASH) is a progressing form of NAFLD, and recently many studies have reported that it could eventually develop into hepatocellular carcinoma (HCC). We previously reported that 6-month-old male galectin-3 knockout (gal3,/,) mice developed clinicopathological features similar to those of NAFLD in humans. Our aim was to investigate the changes in liver histology in gal3,/, mice by long-term observation. Methods:, We initially investigated three 15-month-old gal3,/, mice, of which two developed multiple liver nodules with dysplastic changes. Then, we histopathologically examined the liver specimens of the 15-, 20- and 25-month-old gal3,/, mice and attempted to evaluate the liver morphology by contrast enhanced computed tomography (CT) before sacrifice. Results:, At the age of 15 months or later, gal3,/, mice developed liver nodules with varying degrees of architectural and nuclear atypia based on mild to moderate delicate zone 3 fibrosis. In addition, we successfully confirmed the presence of some of the liver nodules by CT. We report herein that gal3,/, mice develop dysplastic liver nodules and HCC. Conclusions:, We believe that it would be interesting to use this murine model to investigate liver carcinogenesis based on a natural history of NAFLD. Furthermore, CT scanning might be a useful tool for longitudinal evaluation of morphological changes in vivo. [source]


    Service provision for elderly depressed persons and political and professional awareness for this subject: a comparison of six European countries

    INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 5 2003

    Abstract Objective Under-treatment of depression in late-life is a subject of rising public health concern throughout Europe. This study investigates and compares the availability of services for depressed elderly persons in Denmark, France, Germany, Sweden, Switzerland and the UK. Additionally, it explores factors that might contribute to an adequate services supply for depressed elderly people. Method Review of the literature and guide supported expert interviews. Analysis of the practice of care provision for depressed elderly persons and of indicators for political and professional awareness, such as university chairs, certification processes and political programmes in gerontopsychiatry. Results Only Switzerland and the UK offer countrywide community-oriented services for depressed elderly persons. Clinical experience in treating depression in late-life is not regularly acquired in the vocational training of the concerned professionals. Indicators suggest that the ,medical society' and health politics in Switzerland and the UK regard psychiatric disease in the elderly more importantly than it is the case in the other investigated countries. Conclusions Service provision for depressed elderly persons seems to be more elaborated and better available in countries where gerontopsychiatry is institutionalised to a greater extend in the ,medical society' and health politics.

    The feasibility of providing community pharmacy-based services for alcohol misuse: A literature review

    INTERNATIONAL JOURNAL OF PHARMACY PRACTICE, Issue 4 2009
    Dr Margaret C. Watson
    Abstract Objectives Excessive consumption of alcohol is a major public health concern. The use of community pharmacies and pharmacists as sources of public health information and services is gaining greater recognition. The objective of this review was to provide an overview of the evidence on the feasibility, effectiveness and acceptability of providing community pharmacy-based services to address the excessive consumption of alcohol. Methods Electronic databases were searched for the period 1996,2007 to identify relevant evidence. Searches were also conducted of relevant pharmacy and addiction journals. Information was sought from key contacts in pharmacy and alcohol research. Studies were included if they were conducted in a community pharmacy setting. Key findings The review comprised three feasibility studies which included 14 pharmacies and 500 customers. Non-significant reductions in alcohol consumption were reported with two studies following brief interventions by pharmacists. Between 30% and 53% of pharmacy customers were identified as having hazardous or harmful drinking behaviour. Customer opinion of the pharmacy-based alcohol services was not reported. Conclusions There has been little empirical evaluation of the effectiveness of community pharmacy-based services for alcohol misuse. The evidence presented in this review suggests that community pharmacy-based screening is feasible. Organisations and individuals involved with tackling excessive alcohol consumption should consider the inclusion of community pharmacies and pharmacists as part of their strategies to address this problem. Large-scale studies are needed to evaluate the short- and long-term effects and cost-effectiveness of community pharmacy-based interventions to reduce excessive alcohol consumption, as well as to explore the acceptability of the service to users.

    Nurses' attitudes towards adult patients who are obese: literature review

    JOURNAL OF ADVANCED NURSING, Issue 2 2006
    Ian Brown BSc RGN RHV PhD PGCE
    Aims., This paper presents a review of all empirical studies focusing on nurses' attitudes towards adult overweight or obese patients, with the aim of clarifying the dimensions and patterns of these attitudes and the methods by which they have been studied. Background., Obesity has become a common condition and a major public health concern, but it is often associated with negative attitudes and discrimination. Nurses play a key role in providing support and care to patients who are obese. Methods., Electronic searches were carried out on seven databases from inception to December 2004, along with hand-searching of references in relevant studies. The search terms were built around obesity (and related terms), nursing (and its branches) and attitudes (and related terms). Eleven studies met the inclusion criteria. Data were extracted and summarized in tabular form and analysed in relation to the aims of this review during January 2005. Findings., There is relatively little research about nurses' attitudes towards obese patients, and the studies reviewed mostly have weaknesses of sampling and measurement. However, they do consistently suggest that a proportion of nurses have negative attitudes and beliefs, reflecting wider stereotypes within Western cultures. There is also a hint of a more complex mix of attitudes among nurses, some of which may counter the consequences of negative attitudes, but these have not been adequately investigated. A number of variables that influence attitudes of nurses can be identified, including age, gender, experience and the weight/body mass index of the nurse. Conclusion., Further research (both qualitative and quantitative) is needed with more rigorous sampling and, where appropriate, more consistency of measurement. A shift in focus towards the sets of attitudes (positive as well as negative) and behaviours that influence health service quality and outcomes for obese persons would be useful. [source]


    Depleted uranium,the growing concern

    JOURNAL OF APPLIED TOXICOLOGY, Issue 3 2002
    Aqel W. Abu-Qare
    Abstract Recently, several studies have reported on the health and environmental consequences of the use of depleted uranium. Depleted uranium is a heavy metal that is also radioactive. It is commonly used in missiles as a counterweight because of its very high density (1.6 times more than lead). Immediate health risks associated with exposure to depleted uranium include kidney and respiratory problems, with conditions such as kidney stones, chronic cough and severe dermatitis. Long-term risks include lung and bone cancer. Several published reports implicated exposure to depleted uranium in kidney damage, mutagenicity, cancer, inhibition of bone, neurological deficits, significant decrease in the pregnancy rate in mice and adverse effects on the reproductive and central nervous systems. Acute poisoning with depleted uranium elicited renal failure that could lead to death. The environmental consequences of its residue will be felt for thousands of years. It is inhaled and passed through the skin and eyes, transferred through the placenta into the fetus, distributed into tissues and eliminated in urine. The use of depleted uranium during the Gulf and Kosovo Wars and the crash of a Boeing airplane carrying depleted uranium in Amsterdam in 1992 were implicated in a health concern related to exposure to depleted uranium.

    Direct analysis of clinical relevant single bacterial cells from cerebrospinal fluid during bacterial meningitis by means of micro-Raman spectroscopy

    JOURNAL OF BIOPHOTONICS, Issue 1-2 2009
    Michaela Harz
    Abstract Bacterial meningitis is a relevant public health concern. Despite the availability of modern treatment strategies it is still a life-threatening disease that causes significant morbidity and mortality. Therefore, an initial treatment approach plays an important role. For in-time identification of specific bacterial pathogens of the cerebrospinal fluid (CSF) and emerged antimicrobial and adjunctive treatment, microbiological examination is of major importance. This contribution spotlights the potential of micro-Raman spectroscopy as a biomedical assay for direct analysis of bacteria in cerebrospinal fluid of patients with bacterial meningitis. The influence of miscellaneous artificial environments on several bacterial species present during bacterial meningitis was studied by means of Raman spectroscopy. The application of chemometric data interpretation via hierarchical cluster analysis (HCA) allows for the differentiation of in vitro cultured bacterial cells and can also be achieved on a single cell level. Moreover as proof of principle the investigation of a CSF sample obtained from a patient with meningococcal meningitis showed that the cerebrospinal fluid matrix does not mask the Raman spectrum of a bacterial cell notably since via chemometric analysis with HCA an identification of N. meningitidis cells from patients with bacterial meningitis could be achieved.

    How Many Women Have Osteoporosis?

    JOURNAL OF BONE AND MINERAL RESEARCH, Issue 5 2005
    L. Joseph Melton III
    Osteoporosis is widely viewed as a major public health concern, but the exact magnitude of the problem is uncertain and likely to depend on how the condition is defined. Noninvasive bone mineral measurements can be used to define a state of heightened fracture risk (osteopenia), or the ultimate clinical manifestation of fracture can be assessed (established osteoporosis). If bone mineral measurements more than 2 standard deviations below the mean of young normal women represent osteopenia, then 45% of white women aged 50 years and over have the condition at one or more sites in the hip, spine, or forearm on the basis of population-based data from Rochester, Minnesota. A smaller proportion is affected at each specific skeletal site: 32% have bone mineral values this low in the lumbar spine, 29% in either of two regions in the proximal femur, and 26% in the midradius. Although this overall estimate is substantial, some other serious chronic diseases are almost as common. More importantly, low bone mass is associated with adverse health outcomes, especially fractures. The lifetime risk of any fracture of the hip, spine, or distal forearm is almost 40% in white women and 13% in white men from age 50 years onward. If the enormous costs associated with these fractures are to be reduced, increased attention must be given to the design and implementation of control programs directed at this major health problem.

    Effects of Gain Versus Loss Frame Antidrug Ads on Adolescents

    JOURNAL OF COMMUNICATION, Issue 3 2008
    Hyunyi Cho
    Improving the effectiveness of antidrug ads is an important public health concern. Central to achieving this aim is identifying the message strategies that address the differential characteristics of adolescent audiences. This study examined the effects of gain versus loss frame antidrug ads on adolescents with different social and behavioral characteristics. A posttest-only experiment was conducted to examine if these audience factors moderate the effects of message framing. Loss-frame messages, rather than gain-frame messages, were more persuasive for adolescents who report that their friends use drugs. Neither gain nor loss framing had a persuasive advantage for adolescents who report that their friends do not use drugs, although this outcome may be the result of a ceiling effect. Implications of the results for future theory and research are discussed. [source]


    Invasiveness and Intracellular Growth of Multidrug-Resistant Salmonella and Other Pathogens in Caco-2 Cells

    JOURNAL OF FOOD SCIENCE, Issue 2 2007
    S.-H. Kim
    ABSTRACT:, The increase of multidrug-resistant pathogens of human and animal origins is a major public health concern. For a better understanding of the health consequences of multidrug-resistant bacteria transmitted from animal products to humans, the host interaction of zoonotic Salmonella isolates along with other pathogenic and commensal bacteria was evaluated using a human intestinal Caco-2 cell system. Multidrug-resistant S. Agona, S. Heidelberg, and S. Typhimurium possessed plasmid-mediated class 1 integrons. The S. Typhimurium DT104 isolate from ground beef showed the well-known genotypic and phenotypic resistance characteristics of the species, and contained the chromosomally located class 1 integron. Among the multidrug-resistant Salmonella isolates, the S. Heidelberg 219 had the highest invasion number at 1.0 × 104 CFU/mL, followed by the S. Typhimurium DT104 isolate at 7.7 × 103 CFU/mL. Listeria monocytogenes was the best performer among the tested species in invading the Caco-2 cell. Multidrug-resistant opportunistic pathogens Klebsiella pneumoniae and Pseudomonas aeruginosa were also able to invade the cells. The invasion of S. Heidelberg 219, S. Typhimurium DT104, L. monocytogenes, K. pneumoniae, and P. aeruginosa into the Caco-2 cells was not affected even in the presence of commensal E. coli. During the intracellular growth of S. Heidelberg 219, S. Typhimurium DT104, and L. monocytogenes, the bacterial counts increased 2 log cycles in 9 h in the Caco-2 cells. Therefore, these strains could rapidly proliferate after their invasion into the cells. [source]


    When intimate partner violence against women and HIV collide:Challenges for healthcare assessment and intervention

    JOURNAL OF FORENSIC NURSING, Issue 2 2010
    FAAN, Kimberly Adams Tufts DNP, WHNP-BC
    Abstract Intimate Partner Violence (IPV) and Human Immunodeficiency Virus (HIV) both constitute major public health issues that impact the overall health of women. IPV, including sexual assault, remains a persistent public health concern that has proven to be both difficult and significantly dangerous to prevent and treat. Based on data from UNAIDS more than 14.5 million women were living with HIV by the end of 2005. IPV and HIV are often interrelated. Exposure to IPV has been associated with an increased risk for contracting HIV and women who are living with HIV may be more likely to become victims of IPV. Implications: comprehensive care and services have to be offered in the context of where women seek health care. Screening and effective intervention for IPV are essential components of HIV-related services including prevention programming, voluntary counseling and testing, and treatment. Including IPV-related services into the context of HIV-related services delivers the message that violence is not a taboo topic in the health-care setting. [source]


    Violence education in nursing: critical reflection on victims' stories

    JOURNAL OF FORENSIC NURSING, Issue 1 2008
    Angela Frederick Amar PhD
    Abstract Violence against women is a major public health concern. This paper describes an educational strategy to increase nursing students' understanding of the experience of violence and to foster recognition and intervention with victims of violence. Students in an elective course were asked to critically reflect on the personal stories of victims/survivors of violence. The assignment provided four learning opportunities that include examination of societal myths on sexual victimization, understanding the lived experience of the victim, exploration of personal beliefs and values, and the relationship of the individual's experience to theoretical content of the course. Students gave permission for the use of quotes from papers to illustrate the learning opportunities. [source]


    Concurrent Detection of Heroin, Fentanyl, and Xylazine in Seven Drug-related Deaths Reported from the Philadelphia Medical Examiner's Office

    JOURNAL OF FORENSIC SCIENCES, Issue 2 2008
    Stella C. Wong D.O.
    Abstract:, Recreational drugs, such as cocaine and heroin, are often adulterated with other pharmacological agents to either enhance or diminish the drug effects. Between April 21, 2006 and August 8, 2006, the Philadelphia Medical Examiner's Office detected xylazine (a veterinary sedative) and fentanyl (a synthetic opioid) in specimens taken from seven cases. Initial immunoassay screening was performed on urine and blood for fentanyl, opiate, cocaine, phencyclidine (PCP), and benzodiazepines. All tests reported positive were confirmed by gas chromatography-mass spectrometry. All seven xylazine positive cases tested positive for fentanyl and six cases tested positive for 6-acetylmorphine (a metabolite and definitive marker for heroin). The seventh case was positive for morphine and had a history of heroin abuse. Xylazine was present in urine in all seven cases and blood levels were detected in three cases. The blood concentrations ranged from trace to 130 ng/mL. Fentanyl was present in the blood and urine in each case and blood concentrations ranged from 4.7 to 47 ng/mL. Adulteration of illicit drugs has become an epidemic health concern for drug users. Healthcare professionals need to be aware of this issue, so the patients can be treated in an effective, timely manner. [source]


    Barriers to the self-care of type 2 diabetes from both patients' and providers' perspectives: literature review

    JOURNAL OF NURSING AND HEALTHCARE OF CHRONIC ILLNE SS: AN INTERNATIONAL INTERDISCIPLINARY JOURNAL, Issue 1 2009
    Sandra PY Pun MHA
    Aim., To review systematically the literature about barriers to diabetes self-care from both patients' and healthcare providers' perspectives. Background., Diabetes mellitus is a global health concern due to rapidly increasing prevalence. The healthcare costs for diabetes care and related complications are high. Tight glycaemic control achieved by intensive therapy has been shown to lower the risk of complications. Despite the provision of comprehensive management programmes, patients are often unable to achieve the desired outcomes. It is essential to understand the barriers to diabetes self-care in order to promote successfully self-care behaviours. Methods., A search of OVID Medline (R), CINAHL, Cochrane Library and British Nursing Index was carried out during 1986,2007 using keywords: Type 2 Diabetes Mellitus, self care, patient compliance, patient adherence and barriers to diabetes self care. Manual searching of relevant nursing journals and sourcing of secondary research extended the search. Results., A total of 16 original research papers using various methods including survey, descriptive correlational, sequential explanatory mixed-method and qualitative exploratory design were reviewed. In total, over 8900 patients and 4550 healthcare providers were recruited from over 28 countries in these studies. Major barriers identified included psychosocial, socioeconomic, physical, environmental and cultural factors. Conclusions., Healthcare providers can enhance patient empowerment and participation with family support to achieve feasible targets. Better health care delivery systems and reforms that improve affordability, accessibility, and efficiency of care are essential for helping both providers and patients to meet desirable standards of diabetes care. Relevance to clinical practice., Understanding barriers to diabetes self-care is the first step in facilitating providers to identify their role in enabling patients to overcome these barriers. Healthcare providers can develop strategies to clarify and individualise treatment guidelines, implement continuing education, improve communication skills, and help motivate patients to achieve desired behavioral changes.

    Rediscovering the "M" in "MCH": Maternal Health Promotion After Childbirth

    JOURNAL OF OBSTETRIC, GYNECOLOGIC & NEONATAL NURSING, Issue 3 2000
    THOUGHTS & OPINIONS
    Although maternal mortality is not a major health concern in the United States, evidence is accruing that after 6 weeks postpartum mothers continue to face mental and physical health, lifestyle, and parenting concerns. Exemplar areas for enhanced maternal health promotion after childbirth include (a) lifestyle changes in exercise, nutrition, and smoking, and (b) psychosocial well-being, particularly mood and body image. Research on health of women after childbirth supports rethinking the scope and duration of maternal health promotion. [source]


    Binge Drinking and Suboptimal Self-Rated Health Among Adult Drinkers

    ALCOHOLISM, Issue 8 2010
    James Tsai
    Background:, Binge drinking accounts for more than half of the 79,000 annual deaths in the United States that are owing to excessive drinking. The overall objective of our study was to examine the prevalence of binge drinking and consumption levels associated with suboptimal self-rated health among the general population of adult drinkers in all 50 states and territories in the United States. Methods:, The study included a total of 200,587 current drinkers who participated in the 2008 Behavioral Risk Factor Surveillance System (BRFSS) survey. We estimated the prevalence of binge drinking (i.e., ,5 drinks on 1 occasion for men or ,4 drinks on 1 occasion for women) and heavy drinking (i.e., an average of >14 drinks per week for men or >7 drinks per week for women), as well as the average number of binge episodes per person during a 30-day period. Odds ratios were produced with multivariate logistic regression models using binge-drinking levels as a predictor; status of suboptimal self-rated health was used as an outcome variable while controlling for sociodemographic, health, and behavioral risk factors. Results:, We estimate that 34.7 million adult drinkers in the United States engaged in binge drinking in 2008, including an estimated 42.2% who reported either heavy drinking or at least 4 binge-drinking episodes in a 30-day period. Binge drinking with such levels was associated with a 13,23% increased likelihood of reporting suboptimal self-rated health, when compared to the nonbinge drinkers. Conclusions:, Binge drinking continues to be a serious public health concern. Frequent binge drinkers or binge drinkers who consume alcohol heavily are especially at risk of suboptimal self-rated health. Our findings underscore the importance of broad-based implementation in health care settings of screening for and brief interventions to address alcohol misuse, as well as the continuing need to implement effective population-based prevention strategies to reduce alcohol-related morbidity and mortality.
