Selected AbstractsWhy Girls Smoke: A Proposed Community-Based Prevention ProgramJOURNAL OF OBSTETRIC, GYNECOLOGIC & NEONATAL NURSING, Issue 5 2001Mary Ann Faucher CNM Objectives: To review the literature on reasons teenage girls start smoking and to identify the role and opportunities for nurses to have an impact on this public health problem. In addition, a proposed smoking prevention program targeted to teenage girls is presented. Data Sources: Information was gathered from professional journals and texts and from MEDLINE and PROQUEST. Keywords used in the searches were smoking prevention, tobacco use, smoking and adolescents, teenage girls and smoking, health education and smoking, and smoking prevention programs. Data Synthesis and Conclusions: Smoking initiation in teenage girls is a problem with ramifications for individual health as well as for public health. Although the literature demonstrates the rising incidence of smoking in teenage girls and evidence suggests the reasons girls start smoking differ from those of their male counterparts, a dearth of information on smoking prevention programs exists for this population. It is reasonable to assume that the best practices for adolescent smoking prevention can be applied to programs specifically for girls, along with efforts to address social influences, self-image, and self-esteem, which may be particularly important to teenage girls. The theory of reasoned action provides a framework for prevention strategies that target the behavioral beliefs and attitudes that influence teenage girls to smoke. Nurses can educate themselves about contributing factors that lead teenage girls to start smoking. Implementing this knowledge into nursing practice in a variety of settings could help meet the Healthy People 2010 goals of reducing teenage smoking to 16%. [source] Attributes of an ideal oral health care systemJOURNAL OF PUBLIC HEALTH DENTISTRY, Issue 2010DrPH, Scott L. Tomar DMD Abstract Objectives: The sense of urgency concerning the inadequacies of the current U.S. oral health care system in better preventing oral diseases, eliminating oral health disparities, and ensuring access to basic oral health services has increased in recent years. This paper sought to articulate the attributes that an ideal oral health care system would possess, which would be consistent with the principles of the leading authorities on the public's health. Methods: The authors reviewed policy statements and position papers of the World Health Organization, The Institute of Medicine, The American Public Health Association, Healthy People 2010 Objectives for the Nation, and the American Association of Public Health Dentistry. Results: Consistent with leading public health authorities, an ideal oral health care system would be have the following attributes: integration with the rest of the health care system; emphasis on health promotion and disease prevention; monitoring of population oral health status and needs; evidence-based; effective; cost-effective; sustainable; equitable; universal; comprehensive; ethical; includes continuous quality assessment and assurance; culturally competent; and empowers communities and individuals to create conditions conducive to health. Conclusions: Although there are some attributes of an ideal oral health care system on which the United States has made initial strides, it falls far short in many areas. The development of an oral health care delivery system that meets the characteristics described above is possible but would require tremendous commitment and political will on the part of the American public and its elected officials to bring it to fruition.

[source] Overview and Summary: School Health Policies and Programs Study 2006JOURNAL OF SCHOOL HEALTH, Issue 8 2007Laura Kann PhD ABSTRACT Background:, The School Health Policies and Programs Study (SHPPS) 2006 is the largest, most comprehensive assessment of school health programs in the United States ever conducted. Methods:, The Centers for Disease Control and Prevention conducts SHPPS every 6 years. In 2006, computer-assisted telephone interviews or self-administered mail questionnaires were completed by state education agency personnel in all 50 states plus the District of Columbia and among a nationally representative sample of districts (n = 538). Computer-assisted personal interviews were conducted with personnel in a nationally representative sample of elementary, middle, and high schools (n = 1103) and with a nationally representative sample of teachers of classes covering required health instruction in elementary schools and required health education courses in middle and high schools (n = 912) and teachers of required physical education classes and courses (n = 1194). Results:, SHPPS 2006 describes key school health policies and programs across all 8 school health program components: health education, physical education and activity, health services, mental health and social services, nutrition services, healthy and safe school environment, faculty and staff health promotion, and family and community involvement. SHPPS 2006 also provides data to monitor 6 Healthy People 2010 objectives. Conclusions:, SHPPS 2006 is a new and important resource for school and public health practitioners, scientists, advocates, policymakers, and all those who care about the health and safety of youth and their ability to succeed academically and socially. [source] Clinical use of physical activity measuresJOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 2 2009CRNP (Associate Professor), Lorraine M Reiser PhD Abstract Purpose:, To provide a review of physical activity measures and subjective and objective methods of its measurement. Considerations for the use of these measurements in research and practice will be discussed. Data sources:, The PubMed, CINAHL, and Health and Psychosocial Instruments databases, and the Centers for Disease Control Web site were searched using the search term "Physical Activity Measurement." Conclusions:, Physical activity is a lifestyle factor that is a key focus in chronic disease,related research, prevention, and interventions. Healthy People 2010 set goals of decreasing the prevalence of preventable diseases by encouraging healthier lifestyle patterns. Shifts toward more sedentary lifestyles have resulted in increases in life-limiting disease states, including obesity, diabetes, heart disease, cancer, and osteoporosis. Physical activity measurements have been used widely in research studies but are less commonly used in primary care. Measuring individuals' physical activity levels as part of the health assessment will enhance the provider's ability to engage in health promotion and suggest health protection interventions. The strengths, weaknesses, and potential applications to practice of physical activity measures are summarized in an effort to familiarize nurse practitioners (NPs) with commonly used tools and encourage integration of physical activity assessment into their current practice. Implications for practice:, NPs are in an ideal position to promote health by encouraging appropriate amounts of physical activity. Screening, health promotion, and disease prevention are part of the core competencies of NP practice established by the National Organization of Nurse Practitioner Faculties. Increased knowledge of physical activity measures will enhance the NP's ability to evaluate relevant physical activity research for use in evidence-based practice. Incorporation of simple yet appropriate physical activity measurements into practice will expand the NP's ability to identify and thus address sedentary lifestyles in their clientele. [source] Primary care health issues among men who have sex with menJOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 4 2006Royal Gee MSN Abstract Purpose: The purpose of the article is to examine "appropriate" health care for men who have sex with men (MSM), which is not to suggest "special" health care. As a group, MSM are at increased risk for sexually transmitted infections, anal cancer, and mental health disorders. Focus areas in this article will address health issues that the primary care nurse practitioner (NP) may encounter in clinical practice: anal carcinoma, sexually transmitted diseases (STDs), high-risk sexual practices, depression, and substance abuse were topics chosen for inclusion in this article. These topics were among those highlighted in the Healthy People 2010 Companion Document for LGBT Health, which served to examine the healthcare disparities and lack of access to needed services related to sexual orientation. Data source: Extensive literature review of research articles, journals, clinical practice guidelines, books, and public health department Internet Web sites. Conclusions: There are unique health disparities that exist for MSM related to social, emotional, and mental health factors, in addition to physical issues such as STDs. There is an increasing need for primary care providers to be aware of these disparities, as well as the factors that influence these disparities, in order to provide multidimensional care and health counseling that is unique to NP practice. Implications for practice: Both the primary care NP and the patient should be aware of the unique healthcare issues among MSM that should be incorporated into the patient's routine health maintenance program. As primary care providers, it is within the standards of practice for NPs to provide culturally competent care, along with health promotion and disease prevention for MSM.

Nottingham MPH The outcome is an evolving universitycommunity partnership designed to meet changing workforce and community health needs in the heart of rural Appalachia. West Virginia University's (WVU's) application of the original Carnegie Commission AHEC recommendations (1970) resulted in the Charleston AHEC, now part of the Robert C. Byrd Health Sciences Center of WVU. AHEC today trains more than 135 residents and interns, and one-third of the third-year and fourth-year WVU medical students. Charleston offers clinical and continuing education for nurses, dentists, pharmacists, and allied health professionals. A health sciences library, distance learning, and a neiwork of primary care clinics help define Charleston's unique AHEC role. This AHEC hub continues to meet the classic Carnegie goals of recruiting and retaining health professionals, and providing access to care in the original service area and statewide. Based on the Charleston experience, four new federally funded AHECs are being developed to link rural primary care residencies with the state-funded West Virginia rural health education partnerships. These rural consortia AHECs are applying the concept of community competency, a performance-based methodology, to integrate learning while achieving the goals of Healthy People 2010. [source] Public Health Rural Health Priorities in America: Where You Stand Depends on Where You SitTHE JOURNAL OF RURAL HEALTH, Issue 3 2003Larry Gamm PhD Methods: Analysis of responses to a mail survey sent to 999 rural health leaders, with 501 responses. Respondents were asked to rank importance to rural health of focus areas named in Healthy People 2010 Findings: There was substantial agreement on top rural health priorities among state and local rural health leaders across the 50 states. "Access to quality health services" was the top priority among leaders of state-level rural agencies and health associations, local rural public health agencies, rural health clinics and community health centers, and rural hospitals. It was the top priority across all 4 major census regions of the nation as well. The next 4 top-ranking rural priorities,"heart disease and stroke,""diabetes,""mental health and mental disorders," and "oral health",were selected as 1 of the top 5 rural priorities by one third or more of respondents across most groups and regions. At the same time, some observed differences in rural health priorities suggest opportunities for community partnership strategies or for regional multistate policy initiatives by states sharing similar rural health priorities. [source] Healthy Country, Healthy People: Policy Implications of Links between Indigenous Human Health and Environmental Condition in Tropical AustraliaAUSTRALIAN JOURNAL OF PUBLIC ADMINISTRATION, Issue 1 2009Stephen T. Garnett Investment in programs that help Indigenous people undertake work maintaining the environmental health of their country has benefits for the environment as well as the physical, mental and cultural health of the Indigenous people involved. For health these findings have direct implications for some national health policies, service provision to homelands, health promotion and Indigenous health research. There are also direct implications for environmental investment in northern Australia and the design and regulation of markets in resource entitlements. Indirectly the findings should be important for economic, employment and education policies as well as those promoting social harmony. Given the range of benefits there is a strong argument for cross-agency investment in working on country by Indigenous people. [source] Progress in cancer screening practices in the United States,CANCER, Issue 6 2003Results from the 2000 National Health Interview Survey Abstract BACKGROUND Understanding differences in cancer screening among population groups in 2000 and successes or failures in reducing disparities over time among groups is important for planning a public health strategy to reduce or eliminate health disparities, a major goal of Healthy People 2010 national cancer screening objectives. In 2000, the new cancer control module added to the National Health Interview Survey (NHIS) collected more detailed information on cancer screening compared with previous surveys. METHODS Data from the 2000 NHIS and earlier surveys were analyzed to discern patterns and trends in cancer screening practices, including Pap tests, mammography, prostate specific antigen (PSA) screening, and colorectal screening. The data are reported for population subgroups that were defined by a number of demographic and socioeconomic characteristics. RESULTS Women who were least likely to have had a mammogram within the last 2 years were those with no usual source of health care (61%), women with no health insurance (67%), and women who immigrated to the United States within the last 10 years (61%). Results for Pap tests within the last 3 years were similar. Among both men and women, those least likely to have had a fecal occult blood test or endoscopy within the recommended screening interval had no usual source of care (14% for men and 18% for women), no health insurance (20% for men and 18% for women), or were recent immigrants (20% for men and 18% for women). An analysis of changes in test use since the 1987 survey indicates that the disparities are widening among groups with no usual source of care. CONCLUSIONS No striking improvements have been observed for the groups with greatest need. Although screening use for most groups has increased since 1987, major disparities remain. Some groups, notably individuals with no usual source of care and the uninsured are falling further behind; and, according to the 2000 data, recent immigrants also experience a significant gap in screening utilization. More attention is needed to overcome screening barriers for these groups if the population benefits of cancer screening are to be achieved. Cancer 2003;97:1528,40.

However, little is known about the underlying mechanisms. In this study we investigated the nonverbal communication between 101 patients with remitted depression and interviewers. We related the interaction between the patients' and interviewers' behavior to patients' satisfaction with the interview and to the risk of recurrence of depression. We registered the patients' and interviewers' nonverbal displays of involvement during a clinical interview and assessed the patients' satisfaction with the interview. Possible recurrence of depression was assessed within a 2-year follow-up. Based on findings in healthy people, we hypothesized that the more similar the levels of the patients' and interviewers' behavior became during the interview, the more satisfied the patients would turn out to be. Furthermore, we hypothesized that lack of similarity in the levels of the patients' and interviewers' involvement behavior would predict recurrence of depression. Our hypotheses were confirmed: The more the patients' and interviewers' behavior converged, the more satisfied the patients were with the interview and the lower the risk of recurrence of depression. Satisfaction did not mediate the association between convergence and risk of recurrence. Also, no gender effects were found. We conclude that nonverbal communication processes are involved in the risk of recurrence of depression. Remitted people's difficulties in reaching nonverbal convergence with others may hamper them in their interpersonal functioning and, as a consequence, may put them at risk for new episodes of depression.

Kose Summary Blood/injury phobia is one of the specific phobias. The aim of this study was to determine the fear of injection and blood in patients and healthy people. This study was carried out at Tepecik Hospital, Clinical Biochemistry Laboratory and Blood Center. Data were collected from 1500 adults who agreed to participate in the study (237 patients with chronic diseases and 1263 healthy people) during the period from January 2003 to February 2005. All participants completed two self-administered questionnaires (17-item Symptom Questionnaire and 20-item Blood/Injection Fear Scale) after giving blood samples by blood donation. 30.1% of the patients and 19.5% of the healthy adults reported that they had fear of blood/injection. Symptoms related to having blood drawn or injection were more frequently reported among women than men. Patients' educational level was also associated with the Symptom Questionnaire and fear of blood/injection scores. Fear of blood/injection was significantly higher in patients with chronic diseases. Fear of blood/injection should be considered by healthcare professionals as it is important for assessing the treatment-seeking individuals. [source] Lack of association between pro-inflammatory cytokine (IL-6, IL-8 and TNF-,) gene polymorphisms and Graves' diseaseINTERNATIONAL JOURNAL OF IMMUNOGENETICS, Issue 6 2005R.-H. Chen Summary Graves' disease (GD) is a common, autoimmune disease involving the thyroid gland, and it has been previously suggested that pro-inflammatory cytokines are involved in the disease's pathogenesis. The aim of this study was to test whether the interleukin (IL)-6 gene promoter region, or tumour necrosis factor (TNF)-, or IL-8 gene 3,-untranslated region (3,-UTR) polymorphisms could provide useful genetic markers for an individual's susceptibility to GD. A normal control group of 60 healthy people and 95 patients featuring GD were examined. Polymerase chain reaction (PCR)-based restriction analysis was performed for the three gene polymorphisms using endonucleases BsrBI, NcoI and ApaLI, respectively. We found no significant difference between the frequencies of genotype and allelic variants for the IL-6 gene promoter (,572 G/C), the TNF-, gene promoter (,308 A/G) and the IL-8 gene 3,-UTR (2767 A/G) for GD patients and for normal controls. Cytokines are a large group of proteins that may elicit multiple effects upon immunological reactions. It still appears to be very worthwhile to continue to aggressively search for cytokine gene polymorphisms in order to predict the development of such disease. [source] Mechanism of calcium oxalate renal stone formation and renal tubular cell injuryINTERNATIONAL JOURNAL OF UROLOGY, Issue 2 2008Masao Tsujihata Abstract: Formation of calcium oxalate stones tends to increase with age and begins from the attachment of a crystal formed in the cavity of renal tubules to the surface of renal tubular epithelial cells. Though most of the crystals formed in the cavity of renal tubules are discharged as is in the urine, in healthy people, crystals that attach to the surface of renal tubular epithelial cells are thought to be digested by macrophages and/or lysosomes inside of cells. However, in individuals with hyperoxaluria or crystal urine, renal tubular cells are injured and crystals easily become attached to them. Various factors are thought to be involved in renal tubular cell injury. Crystals attached to the surface of renal tubular cells are taken into the cells (crystal,cell interaction). And then the crystal and crystal aggregates grow, and finally a stone is formed. [source] Biocompatibility investigation and urea removal from blood by urease-immobilized HEMA incorporated poly(ethyleneglycol dimethacrylate) microbeadsJOURNAL OF BIOMEDICAL MATERIALS RESEARCH, Issue 1 2003F. Ayhan Abstract The biocompatibility of modified and urease-immobilized poly(ethyleneglycol dimethacrylate/2-hydroxyethylmetacrylate) [poly(EGDMA/HEMA)] microbeads was tested through blood compatibility tests. Twelve percent HEMA incorporated nonporous particles of 105,125 ,m were used in the research. Hydroxyl groups on microbeads were chemically modified by following a three-step procedure that is composed of activation, spacer-arm incorporation (hexamethylene diamine) and, finally, glutaraldehyde bounding. Enzyme urease was immobilized on microbead surfaces, and adsorption of blood proteins in serum and plasma, blood coagulation time, and leukocyte and platelet adhesion were tested. Incubation of 1.5 cc of biological fluid with 100 mg of urease-immobilized poly(EGDMA/HEMA) microbeads at room temperature shows that protein adsorption on surfaces occurs, but protein content after treatment was in the range of healthy people. Adsorbed albumin and total globulin amounts per gram of microbeads is much greater than fibrinogen. Immobilization of urease reduced the protein adsorption and blood coagulation times compared with those of modified microbeads. Prothrombin time (PT) was not altered much, whereas poly(EGDMA/HEMA) microbeads induced a significant increase of activated partial thromboplastin time (APTT). The platelet and leukocyte adhesion slightly increased with the modification of poly(EGDMA/HEMA) and decreased with the introduction of urease. When blood samples were treated with urease-immobilized microbeads, BUN values of patients were lowered to almost acceptable amounts. © 2002 Wiley Periodicals, Inc.

A transporter associated with the antigen processing 1 gene (TAP1) is involved in antigen processing, and is therefore considered to play a role in the pathogenesis of bronchial asthma. The aim of this study was to test whether the polymorphisms of the TAP1 gene are a genetic marker for susceptibility to bronchial asthma. A normal control group comprised of 43 healthy people, and 116 patients with allergic asthma were examined in this study. The polymorphism was detected by polymerase chain reaction (PCR)-based restriction analysis. Associations between atopic bronchial asthma and TAP1 polymorphisms were evaluated. The results revealed no significant differences between normal individuals and asthmatics in regard to the TAP1 gene DpnII polymorphism (P=0.752). However, there was a significant difference between the control and asthma groups as regards the TAP1 gene AccI polymorphism (P=0.020). The odds ratio (OR) of GG homozygotes of the TAP1 AccI polymorphism was 229.8 compared with the AA homozygote group. The results show that the AccI polymorphism may be an indicator for atopic bronchial asthma. J. Clin. Lab. Anal. 17:57,60, 2003. © 2003 Wiley-Liss, Inc. [source] Altered binding of MYF-5 to FOXE1 promoter in non-syndromic and CHARGE-associated cleft palateJOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 1 2009Mario Venza Background:, Three different homozygous loss-of-function mutations of the Forkhead box E1 (FOXE1) gene have been associated with syndromic cleft palate. Here, we screened the entire promoter region to identify the variations in significant consensus motifs affecting FOXE1 transcription. Method:, Genomic DNAs of 35 cleft palate patients, 10 of whom with CHARGE association, 80 unrelated healthy people and 80 unaffected first-degree relatives were analysed by automatic sequencing. The Transcription Element Search System program was employed to identify transcription factor binding sites. The protein-DNA complexes were observed using DNA band-shift assays and oligonucleotide competition analyses. Real-time PCR was used to estimate FOXE1 expression at mRNA level. Results:, In 11 non-syndromic cleft palate patients, a novel non-coding polymorphism (C,G) in the 5,-untranslated region of FOXE1 was found. The variation fell into a putative consensus sequence for the transcription factor MYF-5 and completely impaired the ability of MYF -5 to bind to its motif, as shown by EMSA experiments. As a consequence, a significantly reduced FOXE1 mRNA expression was observed. Conclusions:, In 45% of non-syndromic cleft palate patients, a novel homozygous polymorphism that prevented the binding of MYF -5 to FOXE1 promoter and affected the FOXE1 expression was found. As recent data show the role of MYF-5 in the muscle-dependent craniofacial skeletal development and in the fusion of primary palate and secondary palate, the results reported here strongly suggest a more significant involvement of this factor in the cleft palate onset. [source] Incidence-based estimates of life expectancy of the healthy for the UK: coherence between transition probabilities and aggregate life-tablesJOURNAL OF THE ROYAL STATISTICAL SOCIETY: SERIES A (STATISTICS IN SOCIETY), Issue 1 2008Ehsan Khoman Summary., Will the UK's aging population be fit and independent, or suffer from greater chronic ill health? Life expectancy of healthy people represents the expected number of years of healthy well-being that a life-table cohort would experience if age-specific rates of mortality and disability prevailed throughout the cohort's lifetime. Robust estimation of this life expectancy is thus essential for examining whether additional years of life are spent in good health and whether life expectancy is increasing faster than the decline of rates of disability. The paper examines a means of generating estimates of life expectancy for people who are healthy and unhealthy for the UK that are consistent with exogenous population mortality data. The method takes population transition matrices and adjusts these in a statistically coherent way so as to render them consistent with aggregate life-tables. [source] Hepatitis C virus-specific T-cell immune responses in seronegative injection drug usersJOURNAL OF VIRAL HEPATITIS, Issue 1 2009M. Zeremski Summary., T-cell responses to hepatits C virus (HCV) antigens have been reported in high-risk HCV seronegative persons, suggesting that an effective cellular immune response might be able to clear infection without the development of antibodies. Such findings, however, could be explained by waning antibody or cross-reactivity to other antigens. To address these issues, we evaluated HCV-specific T-cell responses in 26 young (age 18,33 years) aviremic, seronegative injection drug users (IDUs) (median duration of injection, 6 years) by interferon-, enzyme-linked immunospot (ELISpot) assay using 429 overlapping HCV peptides pooled in 21 mixes. Seventeen aviremic, seropositive IDUs (spontaneous resolvers) and 15 healthy people were used as positive and negative controls, respectively. The percentage of patients with HCV-specific cellular immune responses was similar in seronegative and seropositive aviremic IDUs (46%vs 59%, P = 0.4), while these responses were not detected in any of the negative controls. Among the seronegative IDUs, six (23%) had intermediate to very strong responses to 10,20 peptide mixes and another six (23%) had moderately strong responses for two to six mixes. The 12 seronegative IDUs with HCV-specific T-cell responses had higher demographical and behavioural risk profiles than the 14 IDUs without T-cell responses (estimated risk of HCV infection, 0.47 vs 0.26, P < 0.01). In conclusion, HCV-specific T-cell responses are common among high-risk, seronegative IDUs. The responses are broad and are associated with risk factors for HCV exposure, suggesting that they reflect true exposure to HCV in seronegative persons. [source] Subclinical reactivation of herpes simplex virus type 1 in the oral cavityMOLECULAR ORAL MICROBIOLOGY, Issue 5 2000B. Knaup Reactivation in the oral cavity either symptomatically (recrudescence) or without symptoms (recurrence) may contribute to the transmission of herpes simplex virus type 1 (HSV-1), especially in critical areas of exposure such as dentistry. In order to measure the frequency of HSV-1 reactivation, nested polymerase chain reaction (PCR) was performed on oral swabs collected from 30 healthy people over a period of 58,161 days. In total 19 of 25 (76%) seropositive people were PCR-positive at least once, 6 of these 19 (32%) had recrudescence and 13 (68%) had only asymptomatic reactivation. Frequencies of additional recurrences were higher in people showing symptomatic reactivation than in those who had only recurrences. Recrudescence is a risk factor for elevated levels of asymptomatic HSV-shedding. In most cases HSV-1 was detected only by nested PCR investigated by early onset of therapy or time span before sampling.

[source] Executive dysfunction can explain word-list learning disability in very mild Alzheimer's disease: The Tajiri ProjectPSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 1 2004RYUSAKU HASHIMOTO msc Abstract, Elderly people with questionable dementia (i.e. a Clinical Dementia Rating (CDR) of 0.5) have been focused on as representing the borderline zone condition between healthy people and dementia patients. Many of them are known to have pathologic traits of very mild Alzheimer's disease (AD). Although they present mild memory disorder, the underlying mechanism has not been fully investigated. Herein is reported the mechanism of learning disability in very mild AD. Eighty-six CDR 0.5 participants and 101 age- and education-matched healthy controls (CDR 0) were randomly selected from a community in the town of Tajiri, Miyagi Prefecture. The word-recall task of the Alzheimer Disease Assessment Scale,Japanese (i.e. learning and recall of 10 words) was administered. The numbers of words recalled in each trial and those never recalled throughout the trials were compared for the two CDR groups. The serial-position function was depicted for three parts (i.e. primary, middle, and recency). The CDR 0.5 group recalled significantly fewer words than the CDR 0 group. The number of never-recalled words was greater in the CDR 0.5 group. A remarkable difference was found in the middle part of the word list. The number of never-recalled words of the CDR 0.5 group was greater in the middle part. The large number of never-recalled words accounted for the poor learning performance of very mild AD participants. The results suggested that very mild AD participants have difficulty in learning and retaining words in the middle part of the word-list because of a functional decline of the central executive system. [source] Acute changes in carbon dioxide levels alter the electroencephalogram without affecting cognitive functionPSYCHOPHYSIOLOGY, Issue 4 2000Elisabeth Bloch-Salisbury The partial pressure of carbon dioxide in the arterial blood (PaCO2) is usually tightly regulated, yet it varies among healthy people at rest (range ,32,44 mmHg) as well as within an individual during many natural life situations. The present study examined whether modest changes in end-tidal PCO2 (PetCO2; a noninvasive measure of PaCO2) affect electroencephalographic (EEG) activity, cognitive function, and vigilance. Nine adults were ventilated mechanically using a mouthpiece; respiratory rate and breath size were held constant while PetCO2 was set to levels that produced minimal discomfort. Despite discrete changes in EEG, neither acute PetCO2 increases (mean = 47 mmHg) nor decreases (mean = 30 mmHg) from resting levels (mean = 38 mmHg) affected performance on cognitive tasks, latency or amplitude of the N1, P2, or P3 event-related potential, or alertness. Modest changes in PetCO2 may cause significant alterations in the EEG without disturbing cognitive function. [source] Changes in malondialdehyde levels in bronchoalveolar fluid and serum by the treatment of asthma with inhaled steroid and beta2 -agonistRESPIROLOGY, Issue 3 2000Resat Ozaras Objective: Oxidative stress plays an important role in the pathogenesis of asthma. Recent data suggest that clinical indices of the patients with asthma may not correlate with the underlying inflammatory process. We aimed to measure the level of malondialdehyde (MDA), which is a marker of lipid peroxidation, a free radical-mediated process, before and after a well-accepted treatment of asthma. Methodology: Nine non-smoking females and five non-smoking males with mild,moderate asthma were included. Twenty-four age- and sex-matched, non-smoking healthy people (17 females and seven males, mean age 32.1 years, range 20,59) were included for control. After initial evaluation, spirometry, broncoscopy with bronchoalveolar lavage (BAL), and blood sample were maintained. The patients were treated with twice-daily salmeterol inhaler (100 ,g/d) and fluticasone propionate inhaler (500 ,g/d). One month later the investigations were repeated. Serum MDA levels before treatment were compared with both the levels after treatment and levels of controls. Malondialdehyde levels of BAL were compared before and after treatment. Results: Serum MDA level of the patient before treatment was 6.7 ± 0.8 nmol/mL, significantly higher than that of healthy controls; 3.8 ± 0.4, P < 0.001. One month after the treatment, serum MDA level decreased to 5.3 ± 0.7 nmol/mL (P < 0.001). However, this level is still significantly higher than healthy controls (P < 0.0001). Forced expiratory volume in 1 s level of the patients increased from 2.43 ± 0.79 L to 3.50 ± 1.21 L after the treatment (P < 0.001). Conclusion: Although treatment with beta2 -agonist and corticosteroid inhalers for the duration of 1 month reduced lipid peroxidation significantly, it was still at a level significantly higher than healthy controls. The treatment may need a longer duration to improve lipid peroxidation or an alternative regimen which is more effective in controlling inflammation may be warranted. [source] The Duty of States to Assist Other States in Need: Ethics, Human Rights, and International LawTHE JOURNAL OF LAW, MEDICINE & ETHICS, Issue 4 2007Lawrence O. Gostin In this article, Gostin and Archer explore the varied lenses through which governments are obligated to address humanitarian needs. States'responsibilities to help others derive from domestic law, political commitments, ethical values, national interests, and international law. What is needed, however, is clarity and detailed standards so that States can operationalize this responsibility, making it real for developing countries. Transnational cooperation needs to be more effective and consistent to provide assistance for the world's poorest and least healthy people. [source] ABSTRACTS: 1 Implication of soluble receptors of VEGF, sVEGFR-1 and sVEGFR-2, in angiogenesisAMERICAN JOURNAL OF REPRODUCTIVE IMMUNOLOGY, Issue 1 20082TH -6TH JUNE 2008 TOP SELECTED ABSTRACTS, 4TH EMBIC SUMMER SCHOOL, BARCELONA, SPAIN Introduction:, sVEGFR-1 and sVEGFR-2 are soluble forms of the membrane-bound receptors of VEGF. sVEGFR-1 is detected in plasma of pre-eclamptic women, during ischemia and in some cancer cases. sVEGFR-2, was recently detected in plasma of healthy people, in leukaemia and in systemic erythematosus lupus cases. sVEGFR-1 has anti-angiogenic properties in vitro and in vivo but sVEGFR-2 remains uncharacterized and its physiological or pathological role is still unknown. Material and Methods:, The aim of this study was to understand and to characterize the role of sVEGFR2 in angiogenesis and in endothelial function. Results:, In aortic ring assay, an ex vivo model of angiogenesis, sVEGFR1 and sVEGFR2 were able to abolish VEGF-induced angiogenesis. However, when used alone, they induced the formation of a "network", supposed to be vascular in visible microscopy. As they were able to abolish the effect of VEGF on endothelial function but showed no direct effect alone, we performed an immuno-staining of the "vascular network" induced by the soluble receptors. It showed that there were a few endothelial cells but mostly pericytes/smooth muscle cells (PC/SMC). Our first in vitro experiments on PC/SMC showed that sVEGFR-1 and sVEGFR-2 were able to promote the migration of PC/SMC, only in presence of endothelial cells. Conclusions:, Our results evidence that sVEGFR1 and sVEGFR2 inhibit VEGF-induced angiogenesis in a similar way. However, they have also a direct effect on PC/SMC, promoting their migration. Our results suggest that these soluble receptors could act, not only on endothelial cells themselves, but by a direct effect on PC/SMC too. These results contribute to identify factors by which it could be possible to regulate the balance between pro-angiogenic and anti-angiogenic factors, especially in the case of the anti-VEGF drugs used now as anti-cancer therapies in clinics, where a transient "normalization" of the vessels is observed. [source] Evaluation of Urinary 8-Hydroxydeoxyguanine inHealthy Japanese PeopleBASIC AND CLINICAL PHARMACOLOGY & TOXICOLOGY, Issue 5 2006Shingo Kimura The mean urinary concentration of 8-OHdG was 15.2±5.71 ng/mg creatinine. Mean urinary 8-OHdG was not significantly different in terms of age (<45, ,45), gender, smoking (no, <20, ,20), and alcohol consumption (no, occasionally, sometimes and usually). Moreover, multiple regression analysis showed a significant association between urinary 8-OHdG and urinary arsenic (As) or chromium (Cr), and a tendency for association between the former and aluminum (Al) and nickel (Ni). Age, gender and plasma or serum factors including antioxidants, lipid peroxide, HbA1c, BUN, and iron did not show such an association. The present study suggests that natural exposure to toxic metal elements such as As, Cr, and Ni may influence oxidative DNA damage in healthy people under usual environmental management. Therefore, the measurement of urinary metals such as As, Ni and Cr is prerequisite for the study of the relationship between urinary 8-OHdG and other variable factors. [source] CTG repeats at the myotonic protein kinase gene in a healthy Chilean population sampleACTA NEUROLOGICA SCANDINAVICA, Issue 5 2009F. Amenabar Objectives,,, To study the variability at the myotonic dystrophy protein kinase (DMPK) gene in a Chilean sample of healthy people. DM1 is an autosomal dominant disorder caused by an expansion of a (CTG) repeat at the 3,-UTR of the gene DMPK. Healthy individuals have alleles under 35 repeats and diseased individuals have over 50. Methods,,, Genotyping the number of (CTG) repeats at this gene in a sample of healthy Chilean people. Results,,, Allele frequencies were significantly different from those of other populations. The most frequent allele was with five repeats. The frequency of larger alleles (>18 CTG repeats) was 11%, close to the European frequency (12%) and higher than the Japanese (8%) and Aboriginal Pehuenche samples (8%). Conclusions,,, Allelic frequencies in the Chilean sample studied were intermediate between those of the two ancestral populations (European and Pehuenche). [source] Frequent and preferential infection of Treponema denticola, Streptococcus mitis, and Streptococcus anginosus in esophageal cancersCANCER SCIENCE, Issue 7 2004Michihiro Narikiyo Multiple cancers frequently occur in the upper digestive tract. One possible explanation is that specific bacterial infection stimulates the normal epithelium to initiate inflammation and/or promotes carcinogenesis. This study was undertaken to determine which bacterial species is predominantly associated with esophageal cancer. We examined the bacterial diversity in this type of cancer and in the saliva from healthy people by using a culture-independent molecular method. Here we report the preferential and frequent infection of the oral periodontopathic spirochete Treponema denticola (T. denticola), Streptococcus mitis (S. mitis), and Streptococus anginosus (S. anginosus) in esophageal cancer from different regions of the world, and we also describe the induction of inflammatory cytokines by infection of S. anginosus and S. mitis. Our present data suggest that these three bacteria could have significant roles in the carcinogenic process of many cases of esophageal cancer by causing inflammation and by promoting the carcinogenic process, and that eradication of these three bacteria may decrease the risk of recurrence.
