School health education (e.g., classroom training) is an essential component of school health programs; such education promotes the health of youth and improves overall public health. February-May 1996. The School Health Education Profiles monitor characteristics of health education in middle or junior high schools and senior high schools. The Profiles are school-based surveys conducted by state and local education agencies. This report summarizes results from 35 state surveys and 13 local surveys conducted among representative samples of school principals and lead health education teachers. The lead health education teacher is the person who coordinates health education policies and programs within a middle or junior high school and senior high school. During the study period, almost all schools in states and cities required health education in grades 6-12; of these, a median of 87.6% of states and 75.8% of cities taught a separate health education course. The median percentage of schools that tried to increase student knowledge on certain topics (i.e., prevention of tobacco use, alcohol and other drug use, pregnancy, human immunodeficiency virus [HIV] infection, other sexually transmitted diseases, violence, or suicide; dietary behaviors and nutrition; and physical activity and fitness) was > 72% for each of these topics. The median percentage of schools that tried to improve certain student skills (i.e., communication, decision making, goal setting, resisting social pressures, nonviolent conflict resolution, stress management, and analysis of media messages) was > 69% for each of these skills. The median percentage of schools that had a health education teacher coordinate health education was 33.0% across states and 26.8% across cities. Almost all schools taught HIV education as part of a required health education course (state median: 94.3%; local median: 98.1%), and more than half (state median: 69.5%; local median: 82.5%) had a written policy on HIV infection

The prevalence of alcohol consumption has increased in modern dietary life and alcoholic liver injury can follow. Dendrobium huoshanense polysaccharide (DHP) is a homogeneous polysaccharide isolated from Dendrobium huoshanense, which possesses hepatoprotection function. In this study, we investigated the metabolic profiles of serum and liver tissues extracts from control, ethanol-treated and DHP\\ethanol-treated mice using a UHPLC/LTQ Orbitrap XL MS-based metabolomics approach. Our results indicated that DHP alleviated early steatosis and inflammation in liver histology and the metabolomic analysis of serum and hepatic tissue revealed that first, ethanol treatment mainly altered phosphatidylcholines (PCs) including PC (13:0) and phosphocholine, arachidonic acid metabolites including 20-ethyl PGF2α and amino acids including L-Proline; Second, DHP supplementation ameliorated the altered metabolic levels particularly involved in phosphocholine and L-Proline. These data suggested that DHP might restore the perturbed metabolism pathways by ethanol exposure to prevent the progression of alcoholic liver injury. Copyright © 2015 Elsevier B.V.

This research discusses the profile and education of the community health agents. There is no clarity about the kind of professional needed and the appropriate training to the fulfillment of the function. The research is a case study with exploratory methodology and qualitative approach. The data was collected with a focused group, formed by ten agents, intentional selected from those with more time in service in Family Health Strategy teams from the municipality of Santa Maria, Rio Grande do Sul State. The discussions were recorded and transcribed by the researcher. The data was interpreted by content analysis. The results pointed to some important questions concerning the identity of the community health agents: integration on the health team, insertion in the community, profile and education. The profile which emerges from the research, is not different from the one proposed by the Ministry of Health. However, the difference is the professionalization, an initiative assumed by the agent, guided by reality, which he faces in his activity. The gaps, perceived in his formation, cause the agent to construct his professional identity, determined more by the technical aspect of the scientific knowledge than by his social competence as a community agent.

Pyrrolizidine alkaloids (PAs) require metabolic activation to exert cytotoxicity, genotoxicity, and tumorigenicity. We previously reported that (±)-6,7-dihydro-7-hydroxy-1-hydroxymethyl-5H-pyrrolizine (DHP)-derived DNA adducts are responsible for PA-induced liver tumor formation in rats. In this study, we determined that metabolism of riddelliine and monocrotaline by human or rat liver microsomes produced 7-cysteine-DHP and DHP. The metabolism of 7-glutathionyl-DHP by human and rat liver microsomes also generated 7-cysteine-DHP. Further, reaction of 7-cysteine-DHP with calf thymus DNA in aqueous solution yielded the described DHP-derived DNA adducts. This study represents the first report that 7-cysteine-DHP is a new PA metabolite that can lead to DNA adduct formation.

Plants containing pyrrolizidine alkaloids (PAs) are widespread throughout the world and are the most common poisonous plants affecting livestock, wildlife, and humans. PAs require metabolic activation to form reactive dehydropyrrolizidine alkaloids (dehydro-PAs) that are capable of alkylating cellular DNA and proteins, form (±)-6,7-dihydro-7-hydroxy-1-hydroxymethyl-5H-pyrrolizine (DHP)-DNA and DHP-protein adducts, and lead to cytotoxicity, genotoxicity, and tumorigenicity. In this study, we determined that the metabolism of riddelliine and monocrotaline by human and rat liver microsomes in the presence of N-acetylcysteine both produced 7-N-acetylcysteine-DHP (7-NAC-DHP) and DHP. Reactions of 7-NAC-DHP with 2'-deoxyguanosine (dG), 2'-deoxyadenosine (dA), and calf thymus DNA in aqueous solution followed by enzymatic hydrolysis yielded DHP-dG and/or DHP-dA adducts. These results indicate that 7-NAC-DHP is a reactive metabolite that can lead to DNA adduct formation. Copyright © 2016. Published by Elsevier B.V.

Many pyrrolizidine alkaloids (PAs) are hepatotoxic, genotoxic, and carcinogenic phytochemicals. Metabolism of PAs in vivo generates four (±)-6,7-dihydro-7-hydroxy-1-hydroxymethyl-5H-pyrrolizine (DHP)-DNA adducts that have been proposed to be responsible for PA-induced liver tumor formation in rats. In this present study, we determined that the same set of DHP-DNA adducts was formed upon the incubation of 7-glutathione-DHP and 7-cysteine-DHP with cultured human hepatocarcinoma HepG2 cells. These results suggest that 7-glutathione-DHP and 7-cysteine-DHP are reactive metabolites of PAs that can bind to cellular DNA to form DHP-DNA adducts in HepG2 cells, and can potentially initiate liver tumor formation.

The worldwide burden of mental disorders is considerable, and on the rise, putting pressure on health care systems. Current reforms aim to improve the efficiency of mental health care systems by increasing service integration in communities and strengthening primary mental health care. In this context, mental health care professionals (MHPs) are increasingly required to work on interdisciplinary teams in a variety of settings. Little is known, however, about the profiles of MHPs in relation to their perceived work role performance. MHPs in Quebec (N = 315) from four local service networks completed a self-administered questionnaire eliciting information on individual and team characteristics, as well as team processes and states. Profiles of MHPs were created using a two-step cluster analysis. Five profiles were generated. MHPs belonging to profiles labelled senior medical outpatient specialized care MHPs and senior psychosocial outpatient specialized care MHPs perceived themselves as more performing than MHPs in other profiles. The profile labelled low-collaborators was significantly less performing than all other groups. Two other profiles were identified, positioned between the aforementioned groups in terms of the perceived performance of MHPs: the junior primary care MHPs and the diversified specialized care MHPs. Seniority within the team, delivering specialized type of care, and positive team processes were all features associated with profiles where perceived work performance was high. Overall, this study supports the case for initiatives aimed at improving stability and interdisciplinary collaboration in health teams, especially in primary care.

Multidimensional profiles of health status: an application of the grade of membership model to the world health survey.

Directory of Open Access Journals (Sweden)

Alessandra Andreotti

Full Text Available BACKGROUND: The World Health Organization (WHO conducted the World Health Survey (WHS between 2002 and 2004 in 70 countries to provide cross-population comparable data on health, health-related outcomes and risk factors. The aim of this study was to apply Grade of Membership (GoM modelling as a means to condense extensive health information from the WHS into a set of easily understandable health profiles and to assign the degree to which an individual belongs to each profile. PRINCIPAL FINDINGS: This paper described the application of the GoM models to summarize population health status using World Health Survey data. Grade of Membership analysis is a flexible, non-parametric, multivariate method, used to calculate health profiles from WHS self-reported health state and health conditions. The WHS dataset was divided into four country economic categories based on the World Bank economic groupings (high, upper-middle, lower-middle and low income economies for separate GoM analysis. Three main health profiles were produced for each of the four areas: I. Robust; II. Intermediate; III. Frail; moreover population health, wealth and inequalities are defined for countries in each economic area as a means to put the health results into perspective. CONCLUSIONS: These analyses have provided a robust method to better understand health profiles and the components which can help to identify healthy and non-healthy individuals. The obtained profiles have described concrete levels of health and have clearly delineated characteristics of healthy and non-healthy respondents. The GoM results provided both a useable way of summarising complex individual health information and a selection of intermediate determinants which can be targeted for interventions to improve health. As populations' age, and with limited budgets for additional costs for health care and social services, applying the GoM methods may assist with identifying higher risk profiles for decision

To construct profiles of self-reported health indicators to examine differences and similarities between people with lower limb loss and a normative sample (hereafter called the norm) and to compare health indicators between subgroups based on level and etiology of limb loss. Survey. General community. Adults with unilateral lower limb loss (N=1091) participated in this study. Eligibility criteria included lower limb loss due to trauma or dysvascular complications and regular use of a prosthesis. Not applicable. The Patient-Reported Outcomes Measurement Information System 29-item Health Profile version 1.0 measures physical function, pain interference, fatigue, sleep disturbance, anxiety, depression, and satisfaction with participation in social roles. The norm includes 5239 individuals representative of the U.S. general population in sex, age, race, ethnicity, and education. People with lower limb loss reported statistically significantly worse physical function, pain interference, and satisfaction with participation in social roles and significantly less fatigue than did the norm. People with transfemoral (ie, above-knee) amputation significantly differed in physical function from people with transtibial (ie, below-knee) amputation. Similarly, people with amputation due to trauma and dysvascular etiology significantly differed in physical function and satisfaction with social roles after adjusting for relevant clinical characteristics. People with lower limb loss generally report worse physical function, pain interference, and satisfaction with social roles than do the norm. People with dysvascular amputation reported worse physical function and satisfaction with social roles than did people with traumatic amputation. Health indicator profiles are an efficient way of providing clinically meaningful information about numerous aspects of self-reported health in people with lower limb loss.

The objective of this study is to document the health profile of 252 African-American grandparents raising their grandchildren solo, compared with 1552 African-American single parents. The 2012 Behavior Risk Factor Surveillance System is used to compare the specific physical and mental health profiles of these two family groups. The findings suggest solo grandparents have prevalence of many health conditions, including arthritis (50.3 %), diabetes (20.1 %), heart attack (16.6 %) and coronary heart disease (16.6 %). Logistic regression analyses suggest that solo grandparents have much higher odds of several chronic health disorders in comparison with single parents, but this difference is largely explained by age. Although solo grandparents have good access to health care insurance and primary care providers, a substantial percentage (44 %) rate their health as fair or poor. Practice interventions to address African American solo grandparents' health needs are discussed.

Full Text Available Pyrrolizidine alkaloids (PAs are hepatotoxic, genotoxic, and carcinogenic in experimental animals. Because of their widespread distribution in the world, PA-containing plants are probably the most common poisonous plants affecting livestock, wildlife, and humans. Upon metabolism, PAs generate reactive dehydro-PAs and other pyrrolic metabolites that lead to toxicity. Dehydro-PAs are known to react with glutathione (GSH to form 7-GSH-(+/−-6,7-dihydro-7-hydroxy-1-hydroxymethyl-5H-pyrrolizine (7-GS-DHP in vivo and in vitro and 7,9-diGS-DHP in vitro. To date, the phototoxicity of GS-DHP adducts has not been well studied. In this study, we synthesized 7-GS-DHP, a tentatively assigned 9-GS-DHP, and two enantiomeric 7,9-diGS-DHP adducts by reaction of dehydromonocrotaline with GSH. The two 7,9-diGS-DHPs were separated by high performance liquid chromatography (HPLC and their structures were characterized by 1H nuclear magnetic resonance (NMR and 1H–1H correlation spectroscopy (COSY NMR spectral analysis. Photoirradiation of 7-GS-DHP, 9-GS-DHP, and the two 7,9-diGS-DHPs as well as dehydromonocrotaline, dehydroheliotrine, and the 7-R enantiomer of DHP (DHR, by UVA light at 0 J/cm2, 14 J/cm2, and 35 J/cm2 in the presence of a lipid, methyl linoleate, all resulted in lipid peroxidation in a light dose-responsive manner. The levels of lipid peroxidation induced by the two isomeric 7,9-diGS-DHPs were significantly higher than that by 7-GS-DHP and 9-GS-DHP. When 7,9-diGS-DHP was irradiated in the presence of sodium azide (NaN3, the level of lipid peroxidation decreased; lipid peroxidation was enhanced when methanol was replaced by deuterated methanol. These results suggest that singlet oxygen is a product induced by the irradiation of 7,9-diGS-DHP. When irradiated in the presence of superoxide dismutase (SOD, the level of lipid peroxidation decreased, indicating that lipid peroxidation is also mediated by superoxide. These results indicate that lipid

Role of L-type Ca2+ channel isoforms in the extinction of conditioned fear.

2008-05-01

Dihydropyridine (DHP) L-type Ca(2+) channel (LTCC) antagonists, such as nifedipine, have been reported to impair the extinction of conditioned fear without interfering with its acquisition. Identification of the LTCC isoforms mediating this DHP effect is an essential basis to reveal their role as potential drug targets for the treatment of specific anxiety disorders. Ca(V)1.2 and Ca(V)1.3 are the predominant LTCCs in the mammalian brain. However, since no isoform-selective DHP blockers are available, their individual contribution to fear memory extinction is unknown. We used a novel mouse model expressing DHP-insensitive Ca(V)1.2 LTCCs (Ca(V)1.2DHP(-/-) mice) to address this question. In line with previous studies, wild-type (WT) mice treated with systemic nifedipine displayed markedly impaired fear extinction. This DHP effect was completely abolished in Ca(V)1.2DHP(-/-) mice, indicating that it is mediated by Ca(V)1.2, but not by Ca(V)1.3 LTCCs. Supporting this conclusion, Ca(V)1.3-deficient mice (Ca(V)1.3(-/-)) showed extinction identical to the respective WT mice. The inhibition of fear extinction was not observed after intracerebroventricular (i.c.v.) application of different doses of nifedipine, suggesting that this effect is secondary to inhibition of peripheral Ca(V)1.2 channels. The LTCC activator BayK, which lacks neurotoxic effects in Ca(V)1.2DHP(-/-) mice, did not influence the extinction time course. In summary, we demonstrate that LTCC signaling through the Ca(V)1.2 isoform of LTCCs interferes with fear memory extinction, presumably via a peripherally mediated mechanism. Activation of other LTCC isoforms (predominantly Ca(V)1.3) is not sufficient to accelerate extinction of conditioned fear in mice.

Public health leaders play pivotal roles in ensuring the population health for our nation. Since 2000, the number of schools of public health has almost doubled. The scholarly credentials for leaders of public health in academic and practice are important, as they make decisions that shape the future public health workforce and important public health policies. This research brief describes the educational degrees of deans of schools of public health and state health directors, as well as their demographic profiles, providing important information for future public health leadership planning. Data were extracted from a database containing information obtained from multiple Web sites including academic institution Web sites and state government Web sites. Variables describe 2 sets of public health leaders: academic deans of schools of public health and state health directors. Deans of schools of public health were 73% males and 27% females; the PhD degree was held by 40% deans, and the MD degree by 33% deans. Seventy percent of deans obtained their terminal degree more than 35 years ago. State health directors were 60% males and 40% females. Sixty percent of state health directors had an MD degree, 4% a PhD degree, and 26% no terminal degree at all. Sixty-four percent of state health directors received their terminal degree more than 25 years ago. In addition to terminal degrees, 56% of deans and 40% of state health directors held MPH degrees. The findings call into question competencies needed by future public health professionals and leadership and the need to clarify further the level of public health training and degree type that should be required for leadership qualifications in public health.

In this study, the annual cycle of the gonadal steroids testosterone (T), 11-ketotestosterone (11-KT), 17β-oestradiol (E2) and 17α, 20β-dihydroxy-4-pregnen-3-one (DHP) was determined using radioimmunoassay and then compared, for XY males (n=35) and sex-reversed XX males (n=27) rainbow trout, to establish possible endocrinology differences. Both in XY males and sex-reversed XX males, significant correlation was shown between body weight and T (r=0.5046 and 0.34078, respectively; psex-reversed XX males were similar and showed an intense seasonal variation. The highest levels for T and 11-KT were detected from December to April with a peak in January (51.67 ± 5.11 and 61.95 ± 4.25 ng/ml, for XY males and 57.1 ± 5.82 and 59.27 ± 4.84 ng/ml, respectively, for XX males). In addition, there was a positive correlation (psex-reversed XX males (r=0.6019). Concentrations of DHP in XY males also showed seasonal variation with a peak in February (25.18 ± 12.99 ng/ml). However, DHP levels in sex-reversed XX males were undetectable (sex-reversed XX males were similar to those observed in XY males. The only difference in the annual gonadal steroid cycle between XY and sex-reversed XX males was in the DHP profile. © 2009 Blackwell Verlag GmbH.

Full Text Available Objective: Higher education institutions must include curricular strategies that enable students to make decisions according to the values and principles related to their professions. The objective of this study was to determine the values profile expressed by health career students from Southern Chile. Materials and methods: This is a quantitative cross-sectional descriptive study with a purposive sample of 242 (M = 20.1 years old nursing, psychology and kinesiology students to whom the Schwartz Value Survey was applied. Software SPSS 20.0 was used to perform a hierarchical clustering analysis and verify the values dimensions associated with each other. One-way ANOVA with post-hoc tests were conducted to verify the means differences among the scores of the values subscales. Results: Two large homogeneous clusters of values were identified. One consisted of the dimensions of Conformity, Security, Achievement, Tradition and Benevolence, and the other one of the dimensions of Hedonism and Stimulation. During the analysis of means, significant statistical differences were observed between the groups in the dimensions of Universalism, Power, Self-Direction, Benevolence, Conformity, Tradition and Achievement (p < 0.01. The most outstanding means differences were those between psychology and nursing students. In the dimensions of Power, Conformity and Tradition, kinesiology and nursing students showed higher means than psychology students (p < 0.01. Conclusions: The results reveal health career students’ values profile. The next step should be to compare those profiles with the values profile of graduates from each discipline, in order to contribute to the strengthening of the dimensions which students from each career consider important for their professional performance.

Full Text Available ABSTRACT Objective To describe the profile and performance of nutritionists in Primary Health Care. Methods A cross-sectional study was carried out, and all nutritionists in two municipalities of Paraíba, Brazil, were interviewed. Information was collected through structured interviews on demographic characteristics, professional qualification, development of food and nutrition activities, knowledge and use of essential bibliography for the work in Primary Care. Results In one municipality there were 28 teams of the Family Health Strategy and in the other, nineteen teams. In all, nineteen nutritionists were interviewed, fourteen of whom were working in the health teams and five were working exclusively in the Family Health Support Centers. All but one were women and the majority were between 20 and 39 years; the majority (n=10 had no graduate training. Nutritionists from the basic health teams developed more public health nutrition actions, such as defining nutritional care protocols and vitamin A and iron supplementation than those from the Family Health Support Centers (11 versus 1; and 13 versus 1, respectively. About half were satisfied with work in general, and dissatisfaction was related to deficiencies in the availability and quality of anthropometric equipment, physical structure and material. Conclusion Nutritionists work in food and nutrition actions in collective health, emphasizing the importance of qualification and practices that better combine the programmatic agenda of this area with Primary Care.

This study investigated the characteristics and health behavior profiles of 1,803 workers who had experienced industrial accidents. Average weekly exercise days, average number of cigarettes smoked per day, average daily sleep duration, and number of days of alcohol consumption were selected to investigate health behavior profiles. Specifically, latent profile analysis was applied to identify the health behavior profiles of people who had completed industrial accident care; the latent classes were the health-conscious type (n=240), the potential-risk type (n=850), and the high-risk type (n=713). Comparison of the health-conscious and potential-risk types indicated that younger subjects, the employed, and those with lower social status and life satisfaction were more likely to be the potential-risk type. Comparison of the health-conscious and high-risk types revealed that males, younger subjects, the employed, those without chronic illnesses, and those with lower social status and life satisfaction were more likely to be the high-risk type. The results suggest that industrial accident victims who have completed accident care have different health behaviors and it is necessary to improve health promotion based on health type characteristics.

Full Text Available Abstract Background The continual monitoring of population health-related quality of life (HRQoL with validated instruments helps public health agencies assess, protect, and promote population health. This study aimed to determine norms for the French adolescent and adult general population for the Duke Health Profile (DUKE questionnaire in a large representative community sample. Methods We randomly selected 17,733 French people aged 12 to 75 years old in 2 steps, by households and individuals, from the National Health Barometer 2005, a periodic population study by the French National Institute for Prevention and Health Education. Quality of life and other data were collected by computer-assisted telephone interview. Results Normative data for the French population were analyzed by age, gender and self-reported chronic disease. Globally, function scores (best HRQoL=100 for physical, mental, social, and general health, as well as perceived health and self-esteem, were 72.3 (SEM 0.2, 74.6 (0.2, 66.8 (0.1, 71.3 (0.1, 71.3 (0.3, 76.5 (0.1, respectively. Dysfunction scores (worst HRQoL=100 for anxiety, depression, pain and disability domains were 30.9 (0.1, 27.6 (0.2, 34.3 (0.3, 3.1 (0.1, respectively. Conclusion The French norms for adolescents and adults for the DUKE could be used as a reference for other studies assessing HRQoL, for specific illnesses, in France and for international comparisons.

The present work aimed at investigating the pattern recognition receptor (PRR) and immunostimulatory mechanism of a purified Dendrobium huoshanense polysaccharide (DHP). We found that DHP could bind to the surface of macrophages and stimulate macrophages to secrete NO, TNF-α and IL-1β. To unravel the mechanism for the binding of DHP to macrophages, flow cytometry, confocal laser-scanning microscopy, affinity electrophoresis, SDS-PAGE and western blotting were employed to verify the type of PRR responsible for the recognition of DHP by RAW264.7 macrophages and peritoneal macrophages of C3H/HeN and C3H/HeJ macrophages. Results showed that toll-like receptor 4 (TLR4) was an essential receptor for macrophages to directly bind DHP. Further, the phosphorylation of ERK, JNK, Akt and p38 were observed to be time-dependently promoted by DHP, as well as the nuclear translocation of NF-κB p65. These results suggest that DHP activates macrophages via its direct binding to TLR4 to trigger TLR4 signaling pathways. Copyright © 2016 Elsevier Ltd. All rights reserved.

To estimate the profile of intimate partner violence involving women in a scenario of Family Health Strategy in the municipality of Nova Iguaçu (Rio de Janeiro). A transversal study was conducted in four units with a sample of 640 women between the ages of 25 to 64. The phenomena of violence was determined using the tool Revised Conflict Tactics Scales, validated for Brazil. Statistical analysis took into consideration an estimation of prevalence in the calculation of the p values. The situations of violence and the sociodemographic profiles demonstrated a statistically significant relationship with the variables of educational level and housing conditions. Age, ethnicity and economic class demonstrated an association with certain types of violence, varying in type and severity. The study investigated the profile of these situations of violence and enabled reflection regarding the approaches adopted by the Family Health Strategy teams.

"The graying of the globe" has resulted in exponential rise in health care expenses, over-worked health care professionals and a growing patient base suffering from multiple chronic diseases, one of which is diabetes. Consumer health technologies (CHT) are considered important catalysts for empowering health care consumers to take a proactive role in managing their health and related costs. Adoption rate and usability of such devices among the aging is far from being satisfactory. Past studies noted the motivation for adoption by the aging is dependent on the suitability/relevance, perceived usability and anticipated benefits associated with usage of technological innovation. Traditional information technology (IT) development adopts a systematic approach without necessarily using a specific user model that personalizes the system to the aging user groups. The aging patient population has unique needs arising from progressive deterioration in both physiological and psychological abilities. These needs are often ignored in the design, development, trial and adoption of consumer health products resulting in low adoption and usage. The main objective of this research is to investigate the user-centered design (UCD), specifically user profiles and personas, as methodological tools to inform the design and development of CHT devices for an aging population. The adoption of user profile and persona has not received much attention in health care informatics research and, in particular, research involving CHT. Our work begins to fill this void in three ways. We (1) illuminate the process of developing CHT user profiles and personas for a Chinese elder population with a demanding health care needs, i.e., self-management of chronic diabetes, with the hope that the resulting profiles and personas may be used as foundational material for informing the design, development and evaluation of CHT in other similar contexts; (2) call attention to how to further enhance and

The aims of this study were to profile and compare the health and health services characteristics for children with special health care needs (CSHCN), with and without disabilities, and to determine factors associated with unmet need. Secondary data analysis of the 2005-2006 National Survey of Children with Special Health Care Needs was conducted. The sociodemographics, health, and health services of CSHCN with and without disabilities were compared. Multivariable logistic regression was employed to examine factors associated with unmet need for health services. Children from minority racial and ethnic groups and children living in or near poverty were over-represented among CSHCN with disabilities, compared with other CSHCN. Statistically higher percentages of CSHCN with disabilities had behavioral problems (39.6% vs 25.2%), anxiety/depressed mood (46.1% vs 24.0%), and trouble making/keeping friends (38.1% vs 15.6%) compared with other CSHCN. Thirty-two percent of CSHCN with disabilities received care in a medical home compared with 51% of other CSHCN. CSHCN with disabilities had higher rates of need and unmet need than other CSHCN for specialty care, therapy services, mental health services, home health, assistive devices, medical supplies, and durable medical equipment. The adjusted odds of unmet need for CSHCN with disabilities were 71% higher than for other CSHCN. CSHCN with disabilities had more severe health conditions and more health services need, but they less commonly received care within a medical home and had more unmet need. These health care inequities should be amenable to policy and health service delivery interventions to improve outcomes for CSHCN with disabilities. Copyright © 2011 Academic Pediatric Association.

Professionals working in the multidisciplinary field of eHealth vary in their educational background. However, knowledge in the areas of medicine, engineering and management is required to fulfil the tasks associated with eHealth sufficiently. Based on the results of an analysis of national and international educational offers a survey gathering user requirements for the development of knowledge profiles in eHealth was conducted (n=75) by professionals and students. During a workshop the first results were presented and discussed together with the network partners and the attendees. The resulting knowledge profiles contain knowledge areas of all three thematic content categories including fundamentals of medical terminology, standards and interoperability and usability as well as basics of all three content categories. The knowledge profiles are currently applied in a master's degree programme at the UAS Technikum Wien and will be developed further.

Detection of Riddelliine-Derived DNA Adducts in Blood of Rats Fed Riddelliine

Directory of Open Access Journals (Sweden)

Ming W. Chou

2002-09-01

Full Text Available Abstract: We have previously shown that riddelliine, a naturally occurring genotoxic pyrrolizidine alkaloid, induces liver tumors in rats and mice through a genotoxic mechanism mediated by the formation of a set of eight 6,7-dihydro-7-hydroxy-1-hydroxymethyl-5Hpyrrolizine ( DHP-derived DNA adducts. In this study we report the formation of these DHP-derived DNA adducts in blood DNA of rats fed riddelliine. In an adduct formation and removal experiment, male and female F344 rats (8 weeks of age were administered riddelliine by gavage at a single dose of 10.0 mg/kg body weight in 0.1 M phosphate buffer. At 8, 24, 48, and 168 hrs after dosing, the levels of DHP-derived DNA adduct in blood and liver were determined by 32P-postlabeling/HPLC. Maximum DNA adduct formation occurred at 48 hr after treatment. From 48 to 168 hours, the adduct levels in female rat blood were 4-fold greater than those in male rats. In a dose response experiment, female rats were gavaged 0.1 and 1.0 mg/kg doses of riddelliine for three consecutive days and the DHPderived DNA adducts in blood DNA were assayed. The levels of the DHP-derived DNA adducts in blood of rats receiving 0.1 and 1.0 mg/kg doses were 12.9 and 51.8 adducts/107 nucleotides. These results suggest that: (i leucocyte DNA can bind with DHP to form a set of DHP-derived DNA adducts generated in liver; (ii DHP-derived DNA adducts in blood can serve as a potential non-invasive biomarkers for assessing the exposure to riddelliine.

Smith, Rachel A.; Greenberg, Marisa; Parrott, Roxanne L.

2014-01-01

With a growing interest in using genetic information to motivate young adults’ health behaviors, audience segmentation is needed for effective campaign design. Using latent class analysis, this study identifies segments based on young adults’ (N = 327) beliefs about genetic threats to their health and personal efficacy over genetic influences on their health. A four-class model was identified. The model indicators fit the risk perception attitude framework (Rimal & Real, 2003), but the covariates (e.g., current health behaviors) did not. In addition, opinion leader qualities covaried with one profile: those in this profile engaged in fewer preventative behaviors and more dangerous treatment options, and also liked to persuade others, making them a particularly salient group for campaign efforts. The implications for adult-onset disorders, like alpha-1 antitrypsin deficiency are discussed. PMID:24111749

Robust/optimal temperature profile control of a high-speed aerospace vehicle using neural networks.

Yadav, Vivek; Padhi, Radhakant; Balakrishnan, S N

2007-07-01

An approximate dynamic programming (ADP)-based suboptimal neurocontroller to obtain desired temperature for a high-speed aerospace vehicle is synthesized in this paper. A 1-D distributed parameter model of a fin is developed from basic thermal physics principles. "Snapshot" solutions of the dynamics are generated with a simple dynamic inversion-based feedback controller. Empirical basis functions are designed using the "proper orthogonal decomposition" (POD) technique and the snapshot solutions. A low-order nonlinear lumped parameter system to characterize the infinite dimensional system is obtained by carrying out a Galerkin projection. An ADP-based neurocontroller with a dual heuristic programming (DHP) formulation is obtained with a single-network-adaptive-critic (SNAC) controller for this approximate nonlinear model. Actual control in the original domain is calculated with the same POD basis functions through a reverse mapping. Further contribution of this paper includes development of an online robust neurocontroller to account for unmodeled dynamics and parametric uncertainties inherent in such a complex dynamic system. A neural network (NN) weight update rule that guarantees boundedness of the weights and relaxes the need for persistence of excitation (PE) condition is presented. Simulation studies show that in a fairly extensive but compact domain, any desired temperature profile can be achieved starting from any initial temperature profile. Therefore, the ADP and NN-based controllers appear to have the potential to become controller synthesis tools for nonlinear distributed parameter systems.

The synergistic inhibition effect of 5-aminotetrazole (AT) and 4,6-dihydroxypyrimidine (DHP) on the corrosion of cold rolled steel (CRS) in H{sub 3}PO{sub 4} solution was studied by weight loss, potentiodynamic polarization curves, electrochemical impedance spectroscopy (EIS), scanning electron microscope (SEM), quantum chemical calculation and molecular dynamics (MD) methods. The results show that AT exhibits a moderate inhibitive effect, and DHP has a poor effect. However, incorporation AT with DHP significantly improves the inhibitive performance, and yields synergism. The adsorption of AT in the absence and presence of DHP obeys Langmuir adsorption isotherm. AT/DHP mixture acts as a mixed-type inhibitor. The combined AT and DHP molecules co-adsorb on the Fe (001) surface in the nearly flat manner, and the adsorption energy is larger than individual AT or DHP. - Highlights: • There is a synergistic inhibition effect of AT and DHP for steel in H{sub 3}PO{sub 4} solution. • The adsorption of AT whether it is mixed with DHP or not obeys Langmuir isotherm. • The AT/DHP mixture behaves as a mixed-type inhibitor. • E{sub HOMO} increases and E{sub LUMO} decreases in the combined AT and DHP. • AT and DHP co-adsorb on Fe (001) surface with the nearly flat manner.

A considerable number of studies have sought to examine the determinants of elderly health. Nevertheless, few of them incorporate a life-course perspective to analyze the dynamics of transition for both health conditions and their predictors. We utilize a nationally representative longitudinal data set of 4007 Taiwanese aged 60 or over and employ discrete-time duration models to investigate the association between annual mortality and its potential risk factors over a nearly twenty-year period (1989-2007). We place particular emphasis on the inherently dynamic character of Grossman's model, and specifically on how public and private health investment shape the personal health outcome over time. Our results support the hypothesis that depreciation rates depend on personal characteristics. In addition, we find that the dynamic profiles of both public and private health investment significantly influence the elderly mortality. An important implication of our study is that implementing universal health insurance and tobacco control programs are effective channels through which the government improves personal health.

Using cluster analytical procedure, this study aimed (i) to determine whether people could be differentiated on the basis of coping profiles (or unique combinations of coping strategies); and (ii) to examine the relationships between these profiles and perceived stress and health-related behaviors. A sample of 578 French students (345 females, 233 males; M(age)= 21.78, SD(age)= 2.21) completed the Perceived Stress Scale-14 ( Bruchon-Schweitzer, 2002), the Brief COPE ( Muller and Spitz, 2003) and a series of items measuring health-related behaviors. A two-phased cluster analytic procedure (i.e. hierarchical and non-hierarchical-k-means) was employed to derive clusters of coping strategy profiles. The results yielded four distinctive coping profiles: High Copers, Adaptive Copers, Avoidant Copers and Low Copers. The results showed that clusters differed significantly in perceived stress and health-related behaviors. High Copers and Avoidant Copers displayed higher levels of perceived stress and engaged more in unhealthy behavior, compared with Adaptive Copers and Low Copers who reported lower levels of stress and engaged more in healthy behaviors. These findings suggested that individuals' relative reliance on some strategies and de-emphasis on others may be a more advantageous way of understanding the manner in which individuals cope with stress. Therefore, cluster analysis approach may provide an advantage over more traditional statistical techniques by identifying distinct coping profiles that might best benefit from interventions. Future research should consider coping profiles to provide a deeper understanding of the relationships between coping strategies and health outcomes and to identify risk groups. © The Author 2014.

Little has been published about the application profiles and development patterns of open source software (OSS) in health and medical informatics. This study explores these issues with an analysis of health and medical informatics related OSS projects on SourceForge, a large repository of open source projects. A search was conducted on the SourceForge website during the period from May 1 to 15, 2007, to identify health and medical informatics OSS projects. This search resulted in a sample of 174 projects. A Java-based parser was written to extract data for several of the key variables of each project. Several visually descriptive statistics were generated to analyze the profiles of the OSS projects. Many of the projects have sponsors, implying a growing interest in OSS among organizations. Sponsorship, we discovered, has a significant impact on project success metrics. Nearly two-thirds of the projects have a restrictive license type. Restrictive licensing may indicate tighter control over the development process. Our sample includes a wide range of projects that are at various stages of development (status). Projects targeted towards the advanced end user are primarily focused on bio-informatics, data formats, database and medical science applications. We conclude that there exists an active and thriving OSS development community that is focusing on health and medical informatics. A wide range of OSS applications are in development, from bio-informatics to hospital information systems. A profile of OSS in health and medical informatics emerges that is distinct and unique to the health care field. Future research can focus on OSS acceptance and diffusion and impact on cost, efficiency and quality of health care.

On the front line of primary health care: the profile of community health workers in rural Quechua communities in Peru.

2006-05-17

To describe the profile of community health workers--health promoters, traditional birth attendants and traditional healers--in rural Quechua communities from Ayacucho, Peru. Basic quantitative and qualitative information was gathered as part of a community health project implemented between 1997 and 2002 in 40 Andean communities with information from questionnaires, personal interviews and group discussions. The majority of current community health workers are men with limited education who are primarily Quechua speakers undertaking their work on a voluntary basis. Health promoters are mostly young, male, high school graduates. There exists a high drop-out rate among these workers. In contrast, traditional healers and traditional birth attendants possess an almost diametrically opposite profile in terms of age, education and drop-out rates, though males still predominate. At the community level the health promoters are the most visible community health workers. It is very important to consider and to be aware of the profile of community health workers in order to provide appropriate alternatives when working with these groups as well as with the indigenous population, particularly in terms of culture, language and gender issues.

Health Profiles of Mosaic Versus Non-mosaic FMR1 Premutation Carrier Mothers of Children With Fragile X Syndrome

Full Text Available The FMR1 premutation is of increasing interest to the FXS community, as questions about a primary premutation phenotype warrant research attention. 100 FMR1 premutation carrier mothers (mean age = 58; 67–138 CGG repeats of adults with fragile X syndrome were studied with respect to their physical and mental health, motor, and neurocognitive characteristics. We explored the correlates of CGG repeat mosaicism in women with expanded alleles. Mothers provided buccal swabs from which DNA was extracted and the FMR1 CGG genotyping was performed (Amplidex Kit, Asuragen. Mothers were categorized into three groups: Group 1: premutation non-mosaic (n = 45; Group 2: premutation mosaic (n = 41, and Group 3: premutation/full mutation mosaic (n = 14. Group 2 mothers had at least two populations of cells with different allele sizes in the premutation range besides their major expanded allele. Group 3 mothers had a very small population of cells in the full mutation range (>200 CGGs in addition to one or multiple populations of cells with different allele sizes in the premutation range. Machine learning (random forest was used to identify symptoms and conditions that correctly classified mothers with respect to mosaicism; follow-up comparisons were made to characterize the three groups. In categorizing mosaicism, the random forest yielded significantly better classification than random classification, with overall area under the receiver operating characteristic curve (AUROC of 0.737. Among the most important symptoms and conditions that contributed to the classification were anxiety, menopause symptoms, executive functioning limitations, and difficulty walking several blocks, with the women who had full mutation mosaicism (Group 3 unexpectedly having better health. Although only 14 premutation carrier mothers in the present sample also had a small population of full mutation cells, their profile of comparatively better health, mental health, and executive

Pyrrolizidine alkaloid-containing plants are widespread in the world and are probably the most common poisonous plants affecting livestock, wildlife, and humans. Pyrrolizidine alkaloids are among the first chemical carcinogens identified in plants. Previously, we determined that metabolism of pyrrolizidine alkaloids in vivo and in vitro generated a common set of DNA adducts that are responsible for tumor induction. Using LC-ESI/MS/MS analysis, we previously determined that four DNA adducts (DHP-dG-3, DHP-dG-4, DHP-dA-3, and DHP-dA-4) were formed in rats dosed with riddelliine, a tumorigenic pyrrolizidine alkaloid. Because of the lack of an adequate amount of authentic standards, the structures of DHP-dA-3 and DHP-dA-4 were not elucidated, and the structural assignment for DHP-dG-4 warranted further validation. In this study, we developed an improved synthetic methodology for these DNA adducts, enabling their full structural elucidation by mass spectrometry and NMR spectroscopy. We determined that DHP-dA-3 and DHP-dA-4 are a pair of epimers of 7-hydroxy-9-(deoxyadenosin-N(6)-yl) dehydrosupinidine, while DHP-dG-4 is 7-hydroxy-9-(deoxyguanosin-N(2)-yl)dehydrosupinidine, an epimer of DHP-dG-3. With the structures of these DNA adducts unequivocally elucidated, we conclude that cellular DNA preferentially binds dehydropyrrolizidine alkaloid, for example, dehydroriddelliine, at the C9 position of the necine base, rather than at the C7 position. We also determined that DHP-dA-3 and DHP-dA-4, as well as DHP-dG-3 and DHP-dG-4, are interconvertible. This study represents the first report with detailed structural assignments of the DNA adducts that are responsible for pyrrolizidine alkaloid tumor induction on the molecular level. A mechanism of tumor initiation by pyrrolizidine alkaloids is consequently fully determined.

Dihydroartemisinin-piperaquine (DhP) is highly recommended for the treatment of uncomplicated malaria. This study aims to compare the costs, health benefits and cost-effectiveness of DhP and artemether-lumefantrine (AL) alongside "do-nothing" as a baseline comparator in order to consider the appropriateness of DhP as a first-line anti-malarial drug for children in Tanzania. A cost-effectiveness analysis was performed using a Markov decision model, from a provider's perspective. The study used cost data from Tanzania and secondary effectiveness data from a review of articles from sub-Saharan Africa. Probabilistic sensitivity analysis was used to incorporate uncertainties in the model parameters. In addition, sensitivity analyses were used to test plausible variations of key parameters and the key assumptions were tested in scenario analyses. The model predicts that DhP is more cost-effective than AL, with an incremental cost-effectiveness ratio (ICER) of US$ 12.40 per DALY averted. This result relies on the assumption that compliance to treatment with DhP is higher than that with AL due to its relatively simple once-a-day dosage regimen. When compliance was assumed to be identical for the two drugs, AL was more cost-effective than DhP with an ICER of US$ 12.54 per DALY averted. DhP is, however, slightly more likely to be cost-effective compared to a willingness-to-pay threshold of US$ 150 per DALY averted. Dihydroartemisinin-piperaquine is a very cost-effective anti-malarial drug. The findings support its use as an alternative first-line drug for treatment of uncomplicated malaria in children in Tanzania and other sub-Saharan African countries with similar healthcare infrastructures and epidemiology of malaria.

Full Text Available Abstract Background TGF-beta is a multifunctional growth factor involved in regulating a variety of cellular activities. Unlike mammals, the function of TGF-beta in the reproduction of lower vertebrates, such as fish, is not clear. Recently, we showed that TGF-beta1 inhibits gonadotropin- and 17alpha, 20beta-dihydroxyprogesterone (DHP-induced maturation in zebrafish. The aim of the present study was to investigate the mechanisms underlying this action. Method To determine if the effect of TGF-beta1 on oocyte maturation involves transcription and/or translation, ovarian follicles were pre-treated with actinomycin D, a blocker of transcription, and cyclohexamide, an inhibitor of translation, and incubated with hCG or DHP, either alone or in combination with TGF-beta1 and oocyte maturation scored. To determine the effect of TGF-beta1 on mRNA levels of several key effectors of oocyte maturation, three sets of experiments were performed. First, follicles were treated with control medium or TGF-beta1 for 2, 6, 12, and 24 h. Second, follicles were treated with different concentrations of TGF-beta1 (0 to 10 ng/ml for 18 h. Third, follicles were incubated with hCG in the absence or presence of TGF-beta1 for 18 h. At the end of each experiment, total RNA was extracted and reverse transcribed. PCR using primers specific for 20beta-hydroxysteroid dehydrogenase (20beta-HSD which is involved in DHP production, follicle stimulating hormone receptor (FSHR, luteinizing hormone receptor (LHR, the two forms of membrane progestin receptor: mPR-alpha and mPR-beta, as well as GAPDH (control, were performed. Results Treatment with actinomycin D, a blocker of transcription, reduced the inhibitory effect of TGF-beta1 on DHP-induced oocyte maturation, indicating that the inhibitory action of TGF-beta1 is in part due to regulation of gene transcription. Treatment with TGF-beta1 caused a dose and time-dependent decrease in mRNA levels of 20beta-HSD, LHR and mPR-beta in

To understand the needs and health profile of men incarcerated in the Pau dos Ferros Regional Criminal Complex (Rio Grande do Norte, Brazil). Quanti-qualitative research conducted with 30 men incarcerated in November 2012. Semi-structured interviews were the primary data collection method. Descriptive statistics and thematic analysis of the speeches were used for data analysis. The participants' health profile, resulting from deficits in living conditions prior to their imprisonment, is heightened by the degrading conditions of their prison stay, and plays a role in their exclusion and lack of care when admitted as prisoners. The disorders and symptoms most often self-reported by participants were: headache (86.6%), respiratory infections (66.6%), diarrhea (60.0%), stress (60.0%), and depression or deep sadness (56.6%). The responses showed that there is a social gap, especially related to health care, in the prison complex. We recognize a need to ensure the physical and moral integrity of inmates, which is compromised by life in prison; the inmates' health problems and needs differ from those of the general population, and require solutions; the inmates' health-disease process deteriorates due to the mere situation of entering the prison system; the inmates' health problems and health needs are treated with palliative and / or no assistance by those legally responsible for their protection; few human and financial resources exist to ensure health actions for the inmates; and there are no interventions or actions of disease prevention and health promotion.

Metabolites of [ 3 H]progesterone were quantitated from incubations of hypothalamus, pituitary, and uterus of rats during different stages of pregnancy. The hypothalamus, anterior pituitary, and a section of uterus from five rats on Days 1, 8, 15, and 21 of pregnancy were incubated individually with [3H]progesterone and analyzed for metabolite formation by reverse isotopic dilution analysis. The radioactive metabolites present were 5 alpha-pregnane-3,20-dione (5 alpha-DHP), 3 alpha-hydroxy-5 alpha-pregnan-20-one, 20 alpha-hydroxy-4-pregnen-3-one, 20 alpha-hydroxy-5 alpha-pregnan-3-one, and 5 alpha-pregnane-3 alpha, 20 alpha-diol. The major metabolite formed by the hypothalamus and pituitary was 5 alpha-DHP. In the pituitary samples, formation of 5 alpha-DHP was decreased on Days 15 and 21 of pregnancy compared to Day 1, and formation of 20 alpha-hydroxy-5 alpha-pregnan-3-one was decreased on Day 21 compared to Day 1. In the uterine samples, 3 alpha-hydroxy-5 alpha-pregnan-20-one was the major metabolite formed at all stages of pregnancy. The formation of all metabolic products of progesterone by the uterus was increased on Day 21 compared to Days 1, 8, and 15 of pregnancy. No changes in the formation of progesterone metabolites were observed in the hypothalamic samples during pregnancy. It is concluded that there are different profiles in the in vitro metabolism of [3H]progesterone by the hypothalamus, pituitary, and uterus of the rat during the course of pregnancy

Full Text Available Abstract Objective To describe the profile of community health workers – health promoters, traditional birth attendants and traditional healers – in rural Quechua communities from Ayacucho, Peru. Methods Basic quantitative and qualitative information was gathered as part of a community health project implemented between 1997 and 2002 in 40 Andean communities with information from questionnaires, personal interviews and group discussions. Results The majority of current community health workers are men with limited education who are primarily Quechua speakers undertaking their work on a voluntary basis. Health promoters are mostly young, male, high school graduates. There exists a high drop-out rate among these workers. In contrast, traditional healers and traditional birth attendants possess an almost diametrically opposite profile in terms of age, education and drop-out rates, though males still predominate. At the community level the health promoters are the most visible community health workers. Conclusion It is very important to consider and to be aware of the profile of community health workers in order to provide appropriate alternatives when working with these groups as well as with the indigenous population, particularly in terms of culture, language and gender issues.

This study examined the health risk profile of prostitutes in Dublin. Clinical records of all 150 new prostitutes who attended a drop-in clinic for prostitutes in Dublin city during the period 1991-1997 were reviewed. Variables examined included: age, use of injectable drugs, human immunodeficiency virus (HIV) status, hepatitis B and C status, presence of sexually transmitted disease (STD), cervical cytology. Results showed the mean age of the women was 32 years. Among those tested, 2.5% were HIV positive, 5% were hepatitis B positive, 8% were hepatitis C positive and 25% had an STD. Almost 8% were injecting drug users (IDU) with higher prevalences of HIV, hepatitis B and C compared with non-IDU (P < 0.001). The clinic has been successful in providing a health-care facility for the specific health needs of this patient cohort.

Holstein steer calves received a single injection of Miglyol (Sasol Chemical Industries, Ltd.) subcutaneously as a placebo, dihydroheptaprenol (DHP) (4 mg/kg) emulsified with lecithin subcutaneously, DHP in solution in Miglyol (4 mg/kg) subcutaneously, or DHP in solution in Miglyol (4 mg/kg) intranasally. The DHP emulsified in lecithin emulsion administered subcutaneously caused a substantial increase in body temperature, total leukocyte count, total neutrophil count, neutrophil cytochrome-c reduction, and neutrophil iodination 24 hours after administration and, for some of the parameters, at 48 hours. The DHP formulation in Miglyol did not have any of these effects when administered subcutaneously or intranasally. The carrier and formulation of DHP apparently have major effects on the biologic activity of DHP.

Literature suggests that overweight and obese young people use healthcare services more often, but this awaits confirmation in primary care. To identify health profiles of underweight, overweight and obese young people attending general practice and compare them to normal-weight youth and also to explore the weight-related health risks of eating and exercise behaviour in the four different weight categories. This study used a cross-sectional design with baseline data from a trial including 683 young people (14-24 years of age) presenting to general practice. Through computer-assisted telephone interviews data were obtained on number and type of health complaints and consultations, emotional distress, health-related quality of life (HRQoL) and eating and exercise behaviour. General practitioners (GPs) were consulted more often by overweight (incidence rate ratio (IRR): 1.28, 95% CI (1.04 to 1.57)) and obese youth (IRR: 1.54, 95% CI (1.21 to 1.97), but not for different health problems compared with normal-weight youth. The reason for presentation was seldom a weight issue. Obese youth reported lower physical HRQoL. Obese and underweight youth were less likely to be satisfied with their eating behaviour than their normal-weight peers. Exercise levels were low in the entire cohort. Our study highlights the need for effective weight management given that overweight and obese youth consult their GP more often. Since young people do not present with weight issues, it becomes important for GPs to find ways to initiate the discussion about weight, healthy eating and exercise with youth. ISRCTN16059206.

2006-01-01

To begin a renewal of national health policy in Cameroon, a steering committee from the Cameroon Ministry of Health and its partners sought to analyze health demand through a national population survey and supply capacity through a national survey of retail drug stores. A survey of healthcare consumers was also conducted. The present publication describes the results of the consumer survey. Their socioeconomic profile of these consumers was much higher than that of the general population. This indicates that the poorest do not use health facilities or even self-medication. Within the population of healthcare consumers, women and children used private for-profit (60 %) and nonprofit (65 %) private health facilities most often, while men used mainly private pharmacies (60 %) and street drug (medication) sellers (62 %). In all, 85 % of the users of formal drug retailers had had a consultation with a healthcare provider. The average consultation cost was 1,440 CFA Francs, but the 7 % who paid the provider directly had an average cost of 1,794 CFA Francs. In all, 22 % did not pay at all, because of free consultations in some health facilities (40 %), personal relationships with prescribers, or other reasons. Hospitalization costs averaged 4,800 CFA Francs, and medical examinations 4,534 CFA Francs. These two categories had the highest percentage of insured patients (12 % and 5 %). Drug costs were 5,067 CFA Francs from pharmacies and 1,308 CFA Francs in the street. Total healthcare costs per person averaged 14,990 CFA Francs. Weighted, drugs accounted for the largest share, followed by hospitalisation, medical examinations, consultations, and transportation. In the formal sector, less than 10 % reported paying fees directly to the healthcare providers rather than to the HF cashier. Except for consultation in the public sector, paying providers was associated with a lower bill. However, 24 % purchased drugs from the healthcare workers, which indicates that drug sales are

This study aimed to evaluate the within- and between-session reliability of force, velocity and power performances and to assess the force-velocity relationship during the deadlift high pull (DHP). Nine participants performed two identical sessions of DHP with loads ranging from 30 to 70% of body mass. The force was measured by a force plate under the participants' feet. The velocity of the 'body + lifted mass' system was calculated by integrating the acceleration and the power was calculated as the product of force and velocity. The force-velocity relationships were obtained from linear regression of both mean and peak values of force and velocity. The within- and between-session reliability was evaluated by using coefficients of variation (CV) and intraclass correlation coefficients (ICC). Results showed that DHP force-velocity relationships were significantly linear (R² > 0.90, p  0.94), mean and peak velocities showed a good agreement (CV reliable and can therefore be utilised as a tool to characterise individuals' muscular profiles.

Collaborative healthcare environments offer potential benefits, including enhancing the healthcare quality delivered to patients and reducing costs. As a direct consequence, sharing of electronic health records (EHRs) among healthcare providers has experienced a noteworthy growth in the last years, since it enables physicians to remotely monitor patients' health and enables individuals to manage their own health data more easily. However, these scenarios face significant challenges regarding security and privacy of the extremely sensitive information contained in EHRs. Thus, a flexible, efficient, and standards-based solution is indispensable to guarantee selective identity information disclosure and preserve patient's privacy. We propose a privacy-aware profile management approach that empowers the patient role, enabling him to bring together various healthcare providers as well as user-generated claims into an unique credential. User profiles are represented through an adaptive Merkle Tree, for which we formalize the underlying mathematical model. Furthermore, performance of the proposed solution is empirically validated through simulation experiments.

Milk fat composition is important to consumer health. During the last decade, some fatty acids (FA) have received attention because of their functional and beneficial effects on human health. The milk FA profile is affected by both diet and genetics. Differences in milk fat composition are based on biochemical pathways, and candidate genes have been proposed to explain FA profile variation. Here, the association between DGAT1 K232A, SCD1 A293V, and LEPR T945M markers with milk fat composition in southern Chile was evaluated. We selected five herds of Holstein-Friesian, Jersey, Frisón Negro, Montbeliarde, and Overo Colorado cows (pasture-grazed) that received strategic supplementation with concentrates and conserved forages. We genotyped the SNPs and calculated allele frequencies and Hardy-Weinberg equilibrium. Milk fat composition was determined for individual milk samples over a year, and associations between genotypes and milk composition were studied. The most frequent variants for DGAT1, SCD1, and LEPR polymorphisms were GC/GC, C, and C, respectively. The DGAT1 GC/GC allele was associated with lower milk fat and protein content, lower saturated fatty acid levels, and higher polyunsaturated FA (PUFA), n-3 and n-6 FA, and a linolenic acid to cholesterolemic FA ratios, which implied a healthier FA profile. The SCD1 CC genotype was associated with a low cholesterolemic FA content, a high ratio of linolenic acid to cholesterolemic FA, and lower conjugated-linolenic acid and PUFA content. These results suggest the possible modulation of milk fat profiles, using specific genotypes, to improve the nutritional quality of dairy products.

Dr. Ruchama Marton, an Israeli psychiatrist and activist for peace in the Middle East, is a founder of Physicians for Human Rights/Israel. Dr. Jane Green Schaller is a US pediatrician whose 1985 trip to South Africa initiated her human rights involvement, which includes the founding of Physicians for Human Rights. Dr. Judith van Heerden, a primary care physician in South Africa, has worked for reform of prison health care, to establish hospice care, and, most recently, for acquired immune deficiency syndrome (AIDS) education for medical students. Dr. Ma Thida, the only physician not interviewed for this article, is currently held in a Burmese prison because of her work on behalf of the National League for Democracy. The profiles suggest the breadth of human rights work worldwide and are a testament to what physicians can do.

A modified method of extraction and radioimmunological determination (iodine-125) is described, designed to monitor the concentrations of 5..cap alpha..-pregnandione (5..cap alpha..-DHP) in patients showing a pathological course of pregnancy and to examine the role of 5..cap alpha..-DHP blood levels in the development of gestosis. In this study, a control group was compared with two patient groups showing either (a) gestosis or (b) reduced levels of estriol and/or HPL. (1) In gestosis, the levels of 5..cap alpha..-DHP showed significant reductions that were proportionate to the degree of the disease, whereas decreases in these hormone levels were only observed to a minor extent in connection with pathological values of estriol and/or HPL. (2) The age of the patient had no influence on the hormone concentrations. (3) The increases in 5..cap alpha..-DHP seen in multiparae were only slight and did not attain any statistical significance. (4) No links were established between the concentrations of HPL and 5..cap alpha..-DHP in the maternal plasma and the development of the fetus. (5) Significantly reduced values of 5..cap alpha..-DHP were determined in mothers showing disorders of fetoplacental function (birth weights between 2500 and 3500 g) or gestosis (birth weights above 3500 g). (6) There were no relationships between the maternal serum levels of estriol, HPL and 5..cap alpha..-DHP and the sex of the fetus. (TRV).

New media platforms, such as Twitter, provide the ideal opportunity to positively influence the health of large audiences. Saudi Arabia has one of the highest number of Twitter users of any country, some of whom are very influential in setting agendas and contributing to the dissemination of ideas. Those opinion leaders, both individuals and organizations, influential in the new media environment have the potential to raise awareness of health issues, advocate for health and potentially instigate change at a social level. To realize the potential of the new media platforms for public health, the function of opinion leaders is key. This study aims to identify and profile the most influential Twitter accounts in Saudi Arabia. Multiple measures, including: number of followers and four influence scores, were used to evaluate Twitter accounts. The data were then filtered and analysed using ratio and percentage calculations to identify the most influential users. In total, 99 Saudi Twitter accounts were classified, resulting in the identification of 25 religious men/women, 16 traditional media, 14 sports related, 10 new media, 6 political, 6 company and 4 health accounts. The methods used to identify the key influential Saudi accounts can be applied to inform profile development of Twitter users in other countries. © The Author 2015.

Full Text Available Background: In Mexico, there is no available instrument based on a biopsychosocial model to evaluate the impact of periodontal disease on oral health-related quality of life (OHRQL. The Oral Health Impact Profile (OHIP-14 was developed in Australia and the United States based on the same model and can be adapted to evaluate the impact of periodontal disease on OHRQL. Objectives: To adapt the OHIP-14 questions to periodontal disease evaluation and validate the content of this new instrument. Materials and Methods: One expert in periodontics and one expert in health psychology adapted the OHIP-14 to evaluate the impact of periodontal disease on OHRQL, creating the Oral Health Impact Profile applied to Periodontal Disease (OHIP-14-PD. Using the format proposed by Escobar and Cuervo, five experts in periodontics and public health performed the OHIP-14-PD content validation. Results: Item 7 had a compliance rate of 80% for clarity, and the other items, a compliance rate of 100%, for clarity, sufficiency, coherence and relevance. The kappa coefficient showed perfect agreement for items 1 to 6 (k= 1 and 8 to 14, and very high agreement for item 7 (k= 0.967. Conclusion: The OHIP-14-PD shows content validity.

In this paper, bond cleavage reactions are discussed in relation to the softening and solubilization of coal. Were used 9,10-dihydroanthracene (DHA) and 9,10-dihydrophenanthrene (DHP) as models of hydrogen donating compounds in coal, and bibenzyl, 1,2-diethane, benzylphenylether, and 1,5-dibenzylnaphthalene were used as models of bridge structure compounds. They were compared mutually, as to reactivity of coal against DHA and DHP. For the homolytic cleavage of bridges, DHA with excellent radical supplement performance provided excellent hydrogen donating performance. While, for the ipso-position cleavage of bridges, it was found that DHP can act as an effective hydrogen donor. For the reaction between coal and hydrogenated aromatic compounds, cleavage of relatively weak bonds, such as ether linkage and dimethylene linkage, occurred at about 380{degree}C, and hydrogen from DHA or DHP was consumed. On the other hand, the results suggested that the cleavage reaction at ipso-position affected by hydrogen donating solvent is also important at temperature range around 420{degree}C. 2 refs., 3 figs., 1 tab.

We investigated the musculoskeletal health profile of elite female football players (ET) in comparison to untrained (UT) young women subjected to 16 weeks of football training (2 × 1 h per week). DXA scans, blood sampling, sprint testing and Flamingo postural balance testing were carried out for 27 Danish national team players and 28 untrained women, with eight women being tested after training. At baseline total BMD and BMC were 13% (1.305 ± 0.050 versus 1.159 ± 0.056 g · cm(-2)) and 23% (3047 ± 235 versus 2477 ± 526 g) higher (P football training for UT, lean body mass increased by 1.4 ± 0.5 kg and the number of left leg falls decreased by 29% (P footballers have an impressive musculoskeletal health profile compared with untrained controls, but short-term football training seems to reduce the risk of falls and increase bone formation.

Metabolic Activation of the Tumorigenic Pyrrolizidine Alkaloid, Retrorsine, Leading to DNA Adduct Formation In Vivo

Full Text Available Pyrrolizidine alkaloids are naturally occurring genotoxic chemicals produced by a large number of plants. The high toxicity of many pyrrolizidine alkaloids has caused considerable loss of free-ranging livestock due to liver and pulmonary lesions. Chronic exposure of toxic pyrrolizidine alkaloids to laboratory animals induces cancer. This investigation studies the metabolic activation of retrorsine, a representative naturally occurring tumorigenic pyrrolizidine alkaloid, and shows that a genotoxic mechanism is correlated to the tumorigenicity of retrorsine. Metabolism of retrorsine by liver microsomes of F344 female rats produced two metabolites, 6, 7-dihydro-7-hydroxy-1-hydroxymethyl-5H-pyrrolizine (DHP, at a rate of 4.8 ± 0.1 nmol/mg/min, and retrorsine-N-oxide, at a rate of 17.6±0.5 nmol/mg/min. Metabolism was enhanced 1.7-fold by using liver microsomes prepared from dexamethasone-treated rats. DHP formation was inhibited 77% and retrorsine N-oxide formation was inhibited 29% by troleandomycin, a P450 3A enzyme inhibitor. Metabolism of retrorsine with lung, kidney, and spleen microsomes from dexamethasone-treated rats also generated DHP and the N-oxide derivative. When rat liver microsomal metabolism of retrorsine occurred in the presence of calf thymus DNA, a set of DHP-derived DNA adducts was formed; these adducts were detected and quantified by using a previously developed 32P-postlabeling/HPLC method. These same DNA adducts were also found in liver DNA of rats gavaged with retrorsine. Since DHP-derived DNA adducts are suggested to be potential biomarkers of riddelliine-induced tumorigenicity, our results indicate that (i similar to the metabolic activation of riddelliine, the mechanism of retrorsine-induced carcinogenicity in rats is also through a genotoxic mechanism involving DHP; and (ii the set of DHP-derived DNA adducts found in liver DNA of rats gavaged with retrorsine or riddelliine can serve as biomarkers for the

Full Text Available When applied to solving the data modeling and optimal control problems of complex systems, the dual heuristic dynamic programming (DHP technique, which is based on the BP neural network algorithm (BP-DHP, has difficulty in prediction accuracy, slow convergence speed, poor stability, and so forth. In this paper, a dual DHP technique based on Extreme Learning Machine (ELM algorithm (ELM-DHP was proposed. Through constructing three kinds of network structures, the paper gives the detailed realization process of the DHP technique in the ELM. The controller designed upon the ELM-DHP algorithm controlled a molecular distillation system with complex features, such as multivariability, strong coupling, and nonlinearity. Finally, the effectiveness of the algorithm is verified by the simulation that compares DHP and HDP algorithms based on ELM and BP neural network. The algorithm can also be applied to solve the data modeling and optimal control problems of similar complex systems.

Studies into cortical thickness in psychiatric diseases based on T1-weighted MRI frequently report on aberrations in the cerebral cortex. Due to limitations in image resolution for studies conducted at conventional MRI field strengths (e.g. 3 Tesla (T)) this information cannot be used to establish which of the cortical layers may be implicated. Here we propose a new analysis method that computes one high-resolution average cortical profile per brain region extracting myeloarchitectural information from T1-weighted MRI scans that are routinely acquired at a conventional field strength. To assess this new method, we acquired standard T1-weighted scans at 3 T and compared them with state-of-the-art ultra-high resolution T1-weighted scans optimised for intracortical myelin contrast acquired at 7 T. Average cortical profiles were computed for seven different brain regions. Besides a qualitative comparison between the 3 T scans, 7 T scans, and results from literature, we tested if the results from dynamic time warping-based clustering are similar for the cortical profiles computed from 7 T and 3 T data. In addition, we quantitatively compared cortical profiles computed for V1, V2 and V7 for both 7 T and 3 T data using a priori information on their relative myelin concentration. Although qualitative comparisons show that at an individual level average profiles computed for 7 T have more pronounced features than 3 T profiles the results from the quantitative analyses suggest that average cortical profiles computed from T1-weighted scans acquired at 3 T indeed contain myeloarchitectural information similar to profiles computed from the scans acquired at 7 T. The proposed method therefore provides a step forward to study cortical myeloarchitecture in vivo at conventional magnetic field strength both in health and disease.

Full Text Available Indirect spectrophotometric method is described for quantification of five of 1,4-dihydropyridine (1,4-DHP drugs using N-bromosuccinimide (NBS with the aid of indigo carmine (INC dye. The method is based on addition of known excess of NBS to an acidified solution of 1,4-DHP drugs and determining the residual of NBS through its ability to bleach the colour of the used dye; the amount of NBS that reacted corresponded to the amount of drugs. Beer’s law is obeyed in the concentration range 1.25–13.00 μg/mL. Good correlation coefficients (0.998-0.999 were found between the absorbance values and the corresponding concentrations. Limits of detections ranged from 0.141 to 0.500 μg/mL. The proposed method was successfully applied to the analysis of dosage forms; percent of recoveries ranged from 97.31 to 99.46% without interference from any common excipients. The statistical comparison by Student’s t-test and variance ratio F-test showed no significant difference between the proposed and official or reported methods.

To systematically evaluate the literature to investigate associations between social, demographic, economic, psychosocial, and behavioral factors and the self-perception of oral health measured using the Oral Health Impact Profile (OHIP). In this systematic review of the literature, the Preferred Reporting Items for Systematic Reviews (PRISMA) were adapted for the performance of a qualitative metasummary, without meta-analysis. Articles about oral health and associated factors with implications for quality of life were selected, with a focus on the tool for self-rating of the oral health-disease process, the OHIP. Pubmed/National Library of Medicine (NLM) and the Virtual Health Library (Biblioteca Virtual em Saúde - BVS/BIREME) were searched. Articles published between 2001 and 2011 were included. The following Medical Subject Headings (MeSH) were employed: oral health, quality of life, sickness impact profile, and socioeconomic factors. Of 57 articles identified, 20 met the inclusion criteria. The metasummary revealed that a poor self-perception of oral health was associated with unfavorable social, economic, demographic, and psychosocial factors, as well as with undesirable habits and poor clinical oral conditions. There is consensus in the literature about the influence of the investigated factors on the self-perception of oral health and on quality of life. The OHIP is an important aid for determining oral health needs and for developing strategies to control/reduce disease and promote oral health, with a consequent positive impact on quality of life.

2013-06-01

Full Text Available This paper describes progress on formulating a national asbestos profile for the country of Vietnam. The Center of Asbestos Resource, Vietnam, formulated a National Profile on Asbestos-related Occupational Health, with due reference to the International Labor Organization/World Health Organization National Asbestos Profile. The Center of Asbestos Resource was established by the Vietnamese Health Environment Management Agency and the National Institute of Labor Protection, with the support of the Australian Agency for International Development, as a coordinating point for asbestos-related issues in Vietnam. Under the National Profile on Asbestos-related Occupational Health framework, the Center of Asbestos Resource succeeded in compiling relevant information for 15 of the 18 designated items outlined in the International Labor Organization/World Health Organization National Asbestos Profile, some overlaps of the information items notwithstanding. Today, Vietnam continues to import and use an average of more than 60,000 metric tons of raw asbestos per year. Information on asbestos-related diseases is limited, but the country has begun to diagnose mesothelioma cases, with the technical cooperation of Japan. As it stands, the National Profile on Asbestos-related Occupational Health needs further work and updating. However, we envisage that the National Profile on Asbestos-related Occupational Health will ultimately facilitate the smooth transition to an asbestos-free Vietnam.

The purpose of this research was to identify the profile of an excellent nurse manager who can lead effective health care teams. Leadership attributes and competencies that characterize an excellent nurse manager and tools to identify them are lacking in the literature but are required to efficiently and effectively address the growing shortage of registered nurses (RNs) in health care team leadership roles and the critical linkage of these roles to patient outcomes. A profile of an excellent nurse manager was developed on the basis of the responses of nurse managers across the United States who had been identified as excellent or competent by chief nurse executive assessment or/and the Nurse Manager Ability, Leadership, and Support of Nurses staff survey to the Kouzes and Posner Leadership Practices Inventory: Self Instrument. Statistically significant distinctions exist between nurse managers who are excellent and those who are competent as assessed by the Five Practices of Exemplary Leadership, which together comprise the profile of an excellent nurse manager. The Kouzes and Posner Leadership Practices Inventory: Self Instrument can be used to identify, recruit, and develop RNs in the nurse manager role as excellent leaders of effective health care teams.

Full Text Available A novel nicotine hydroxylase was isolated from Pseudomonas sp. ZZ-5 (HSPHZZ. The sequence encoding the enzyme was 1206 nucleotides long, and encoded a protein of 401 amino acids. Recombinant HSPHZZ was functionally overexpressed in Escherichia coli BL21-Codon Plus (DE3-RIL cells and purified to homogeneity after Ni-NTA affinity chromatography. Liquid chromatography-mass spectrometry (LC-MS analyses indicated that the enzyme could efficiently catalyze the conversion of 6-hydroxy-3-succinoylpyridine (HSP into 2,5-dihydroxypyridine (2,5-DHP and succinic acid in the presence of nicotinamide adenine dinucleotide (NADH and flavin adenine dinucleotide (FAD. The kinetic constants (Km, kcat, and kcat/Km of HSPHZZ toward HSP were 0.18 mM, 2.1 s−1, and 11.7 s−1 mM−1, respectively. The optimum temperature, pH, and optimum concentrations of substrate and enzyme for 2,5-DHP production were 30 °C, 8.5, 1.0 mM, and 1.0 μM, respectively. Under optimum conditions, 85.3 mg/L 2,5-DHP was produced in 40 min with a conversion of 74.9%. These results demonstrated that HSPHZZ could be used for the enzymatic production of 2,5-DHP in biotechnology applications.

Public health leadership has been criticized as being ineffective. The public health profession is relatively small. Critics have argued that there is over-emphasis on technical aspects and insufficient use of the 'community as a source of public health actions'. The paper analyses the resources, motivations and skills utilized by high-profile individuals who have made contributions to the public health agenda. The phenomenon of celebrity diplomacy is critiqued. Two exemplars are discussed: Jamie Oliver and Michael Bloomberg. The risks of involving celebrities are also considered. Leaders for public health demonstrate 'a paradoxical blend of personal humility and professional will' to make the 'right decisions happen'. While they may have ego or self-interest, in this context, at least, they channel their ambition for the public health cause, not themselves. Leaders from outside public health may have no understanding of what public health is nor consider their work as part of a wider public health agenda. It is important to understand why they become leaders for public health. This will inform a strategy for how others may be encouraged to collaborate for public health causes. Some key points for working with high-profile leaders for public health are identified. © The Author 2014. Published by Oxford University Press on behalf of Faculty of Public Health.

This country profile for Zambia was compiled between 1998 and 2002. The objectives of the exercise were to first of all avail policymakers, other key decision makers and leaders in Zambia, information about mental health in Zambia in order to assist policy and services development. Secondly, to facilitate comparative analyses of mental health services between countries. The work involved formation of a core group of experts who coordinated the collection of information from the various organizations in Zambia. The information was later shared to a broad spectrum of stakeholders for consensus. A series of focus group discussions (FGDs) supplemented the information collected. There are various factors that contribute to mental health in Zambia. It is clear from the Zambian perspective that social, demographic, economic, political, environmental, cultural and religious influences affect the mental health of the people. With a population of 10.3 million and annual growth rate of 2.9%, Zambia is one of the most urbanized countries in sub-Saharan Africa. Poverty levels stood at 72.9% in 1998. In terms of unemployment, the most urbanized provinces, Lusaka (the capital city), and the copper-belt are the most affected. The gross domestic product (GDP) is US$3.09 billion dollars while per capita income is US$300. The total budget allocation for health in the year 2002 was 15% while the proportion of the GDP per capita expenditure for health was 5.6%. The HIV/AIDS prevalence rates stand at 20% among the reproductive age group 15-49 years. Political instability and wars in neighbouring states has resulted in an influx of refugees. Environmental factors affecting the country include natural and man-made disasters such as floods and drought, mine accidents, and deforestation. To a large extent in Zambia, people who are mentally ill are stigmatized, feared, scorned at, humiliated and condemned. However, caring for mental ill health in old age is positively perceived. It is

This study was designed to test the reliability and validity of an instrument to assess adolescent health status. Reliability and validity were examined by administration to adolescents (ages 11-17 years) in eight schools in two urban areas, one area in Appalachia, and one area in the rural South. Integrity of the domains and subdomains and construct validity were tested in all areas. Test/retest stability, criterion validity, and convergent and discriminant validity were tested in the two urban areas. Iterative testing has resulted in the final form of the CHIP-AE (Child Health and Illness Profile-Adolescent Edition) having 6 domains with 20 subdomains. The domains are Discomfort, Disorders, Satisfaction with Health, Achievement (of age-appropriate social roles), Risks, and Resilience. Tested aspects of reliability and validity have achieved acceptable levels for all retained subdomains. The CHIP-AE in its current form is suitable for assessing the health status of populations and subpopulations of adolescents. Evidence from test-retest stability analyses suggests that the CHIP-AE also can be used to assess changes occurring over time or in response to health services interventions targeted at groups of adolescents.

Background: Recently, under National Health Mission alternate systems of Medicine are mainstreamed in public health care system. Effective action plan generation, logistic arrangement and roll out of these alternate systems of Medicine needs understanding on profile of morbidities among attendees who come to these facilities. Objectives: This study was planned to report profile of morbidities, age and sex differentials in specific morbidities among geriatric attendees in secondary level siddha health facilities. Materials and Methods: A facility based cross sectional study was conducted among elderly person (60 years and above) attending Siddha outpatient department (OPD) from two of the randomly selected sub district level siddha facilities in Erode district, Tamil Nadu, India. Information on socio-demographic variables like age, gender, education and clinical profile (diagnosis) were collected from records already maintained in the siddha OPD. Morbidities were summarized in terms of proportions based on age and gender. Age and sex specific differentials on specific morbidities were compared using ‘z’ test. Results: Of 2710 patients who visited these two siddha facilities during the reference period, 763 (28.1%) patients were elderly. Arthritis (45.2%), neuritis (8.8%), diabetes (6.6%), bronchial asthma (5.2%), hemiplegia (3.7%) were the top five morbidities diagnosed and treated among elderly attending the siddha OPD. There was a predilection towards elderly male for morbidities such as bronchial asthma and hemiplegia compared to elderly female. Similarly, higher proportions of lumbar spondylosis, hypertension and fungal skin diseases were reported among aged 80 years or more compared to elderly aged 60-79 years. Conclusion: Elderly constitute more than one fourth of outpatients load from siddha health facilities. Degenerative diseases like arthritis and non-communicable diseases were the common morbidities in this age group. Geriatric clinics and mobile

Pyrrolizidine alkaloid-containing plants are the most common poisonous plants affecting livestock, wildlife, and humans. The U.S. National Toxicology Program (NTP) classified riddelliine, a tumorigenic pyrrolizidine alkaloid, as "reasonably anticipated to be a human carcinogen" in the NTP 12th Report on Carcinogens in 2011. We previously determined that four DNA adducts were formed in rats dosed with riddelliine. The structures of the four DNA adducts were elucidated as (i) a pair of epimers of 7-hydroxy-9-(deoxyguanosin-N(2)-yl)dehydrosupinidine adducts (termed as DHP-dG-3 and DHP-dG-4) as the predominant adducts; and (ii) a pair of epimers of 7-hydroxy-9-(deoxyadenosin-N(6)-yl)dehydrosupinidine adducts (termed as DHP-dA-3 and DHP-dA-4 adducts). In this study, we selected a nontumorigenic pyrrolizidine alkaloid, platyphylliine, a pyrrolizidine alkaloid N-oxide, riddelliine N-oxide, and nine tumorigenic pyrrolizidine alkaloids (riddelliine, retrorsine, monocrotaline, lycopsamine, retronecine, lasiocarpine, heliotrine, clivorine, and senkirkine) for study in animals. Seven of the nine tumorigenic pyrrolizidine alkaloids, with the exception of lycopsamine and retronecine, are liver carcinogens. At 8-10 weeks of age, female F344 rats were orally gavaged for 3 consecutive days with 4.5 and 24 μmol/kg body weight test article in 0.5 mL of 10% DMSO in water. Twenty-four hours after the last dose, the rats were sacrificed, livers were removed, and liver DNA was isolated for DNA adduct analysis. DHP-dG-3, DHP-dG-4, DHP-dA-3, and DHP-dA-4 adducts were formed in the liver of rats treated with the individual seven hepatocarcinogenic pyrrolizidine alkaloids and riddelliine N-oxide. These DNA adducts were not formed in the liver of rats administered retronecine, the nontumorigenic pyrrolizidine alkaloid, platyphylliine, or vehicle control. These results indicate that this set of DNA adducts, DHP-dG-3, DHP-dG-4, DHP-dA-3, and DHP-dA-4, is a common biological biomarker of

Direct hemoperfusion with polymyxin B-immobilized fiber (PMX-DHP) might be beneficial for treating acute exacerbation (AE) of interstitial pneumonia (IP). Venovenous extracorporeal membranous oxygenation (VV-ECMO) is an emerging tool to avoid ventilator-induced lung injury. This is a report presenting the first three patients with AE of IP treated with a combined therapy of PMX-DHP and VV-ECMO. Patient 1 was a 68-year-old male with acute interstitial pneumonia, patient 2 a 67-year-old male with AE of idiopathic pulmonary fibrosis, and patient 3 a 61-year-old female with AE of collagen vascular disease-associated interstitial pneumonia. All patients were severely hypoxemic and required mechanical ventilation. A combined therapy using PMX-DHP and VV-ECMO was initiated with support of intravenous corticosteroids and antibiotics. Radiological findings, oxygenation and laboratory findings markedly improved and all patients survived without severe complications. A combined therapy of PMX-DHP and VV-ECMO might be a therapeutic option for AE of IP.

Compounds with the structural motif of 1,4-dihydropyridine display a broad spectrum of biological activities, often defined as bioprotective. Among them are L-type calcium channel blockers, however, also derivatives which do not block calcium channels exert various effects at the cellular and organismal levels. We examined the effect of sodium 3,5-bis-ethoxycarbonyl-2,6-dimethyl-1,4-dihydropyridine-4-carboxylate (denoted here as DHP and previously also as AV-153) on X-ray-induced DNA damage and mutation frequency at the HGPRT (hypoxanthine-guanine phosphoribosyl transferase) locus in Chinese hamster ovary CHO-K1 cells. Using formamido-pyrimidine glycosylase (FPG) comet assay, we found that 1-h DHP (10 nM) treatment before X-irradiation considerably reduced the initial level of FPG-recognized DNA base damage, which was consistent with decreased 8-oxo-7,8-dihydro-2'-deoxyguanosine content and mutation frequency lowered by about 40%. No effect on single strand break rejoining or on cell survival was observed. Similar base damage-protective effect was observed for two calcium channel blockers: nifedipine (structurally similar to DHP) or verapamil (structurally unrelated). So far, the specificity of the DHP-caused reduction in DNA damage - practically limited to base damage - has no satisfactory explanation.

The aim of this study was to investigate the relationship between patients' oral health-related quality of life, satisfaction with their dentition, and their personality profiles. Eighty-four patients (30 males and 54 females; mean age 31.9+/-12.7 years) seeking routine dental treatment were recruited for this study. A "Dental Impact on Daily Living" (DIDL) questionnaire was used to assess dental satisfaction and impact on daily living. An "Oral Health Impact Profile" (OHIP) was used to measure self-reported discomfort, disability, and dysfunction caused by oral conditions. Oral health-related quality of life was assessed using the "United Kingdom Oral Health Related Quality of Life" measure (OHQoL-U.K). A "NEO Five Factor inventory" (NEO-FFI) was used to assess personality profiles. The dentition has a measurable impact on daily living as well as with satisfaction with appearance, pain levels, oral comfort, general performance, and eating capability (p=0.000). Younger patients had more profound oral health impacts (p=0.045) and higher neuroticism scores (0.043). OHIP scores were significantly related to OHQoL-UK scores (p=0.000). DIDL scores had significant correlations with OHIP and OHQoL-UK scores (p<0.05). Significant correlations were established between neuroticism and satisfaction with oral comfort, extraversion and total satisfaction and satisfaction with general performance, and openness and satisfaction with appearance (p<0.05). OHIP and OHQoL-UK scores had no significant correlations with psychological profiles. The status of the oral cavity can have a definitive impact on patients' daily living and quality of life regardless age, gender, and level of education. Patients' satisfaction with their dentition has definitive impacts on daily living, quality of life, and dental perceptions. Personality profiles (neuroticism; extraversion, and openness) may influence dental perceptions, play a significant role in shaping satisfaction with dentition, and help

Full Text Available Objective: analyze  profile of users of primary health care services affected by leprosy, as well as the medical professionals and nurses responsible for the follow - up of these patients.   Methods: This is a field study that surveyed the socioeconomic and clinical profile of 26 patients affected by leprosy, attended at the municipal health units of the urban area of ​​Teresina-PI, as well as the professional profile and clinical practices of 15 physicians and 19 nurses responsible for the follow-up of these patients. Results: It was observed a profile of people affected by leprosy, characterized by: individuals aged 50 years or more; predominantly male; with low schooling and income. The clinical characteristics reveal a high prevalence of multibacillary cases of leprosy and with a significant diagnosis of some degree of physical disability. Regarding the profile of the professionals and their clinical behaviors, it was verified that the majority had post-graduation and a long time of experience in primary health care and leprosy control actions, however, it has been shown that they do not always put into practice all actions necessary for the diagnosis and treatment of the disease. Conclusions: The profile of patients with leprosy treated at the municipal health units in the urban area of Teresina was similar to that found in other Brazilian territories, thus evidencing the need to implement public social support policies and more effective diagnostic and therapeutic follow-up practices by reduce the high rates of endemicity of the disease.

In this study we developed a Fast Healthcare Interoperability Resources (FHIR) profile to support exchanging a full pedigree based family health history (FHH) information across multiple systems and applications used by clinicians, patients, and researchers. We used previously developed clinical element models (CEMs) that are capable of representing the FHH information, and derived essential data elements including attributes, constraints, and value sets. We analyzed gaps between the FHH CEM elements and existing FHIR resources. Based on the analysis, we developed a profile that consists of 1) FHIR resources for essential FHH data elements, 2) extensions for additional elements that were not covered by the resources, and 3) a structured definition to integrate patient and family member information in a FHIR message. We implemented the profile using an open-source based FHIR framework and validated it using patient-entered FHH data that was captured through a locally developed FHH tool.

To characterize the distribution of total cholesterol (TC), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C) and triglycerides in primary health care users. We performed a cross-sectional study in a primary care setting, involving 719 general practitioners based on stratified distribution proportional to the population density of each region of Portugal. The first two adult patients scheduled for an appointment on a given day were invited to participate. A questionnaire was applied to assess sociodemographic, clinical and laboratory data including lipid profile. The study included 16 856 individuals (mean age 58.1±15.1 years; 61.6% women). Data on TC, LDL-C, HDL-C and triglycerides were available for 95.9% (n=16 159), 59.1% (n=9956), 95.4% (n=16 074) and 97.9% (n=16 494) of the population, respectively. Hypercholesterolemia (TC ≥200 mg/dl) was detected in 47%, and 38.4% had high levels of LDL-C (≥130 mg/dl). Hypertriglyceridemia (≥200 mg/dl) and low HDL-C (<40 mg/dl) were less prevalent, affecting roughly 13% of the population. Dyslipidemia was more common in middle-aged men and in post-menopausal women. Of the population aged over 40, 54.1% met eligibility criteria for lipid-lowering therapy and 44.7% were medicated with statins, but only 16.0% of these had TC ≤175 mg/dl. Dyslipidemia is highly prevalent in primary health care users in Portugal. It is particularly common in middle-aged men and post-menopausal women, who should be considered target groups for preventive public health measures.

Full Text Available Objective: Adrenal insufficiency (AI is a chronic condition associated with increased mortality and morbidity. The treatment of AI in the last years has been object of important changes due to the development of a dual-release preparation of hydrocortisone. It differs from previous therapeutic strategy as it contemplates a once-daily tablet that allows more closely mimicking the physiological circadian cortisol rhythm. The aim of the study was to evaluate the effects of dual-release hydrocortisone treatment on the glycometabolic profile and health-related quality of life of patients with AI. Design and Methods: In this clinical open trial, we enrolled ten patients with primary AI (41 ± 2.67 years and nine patients with AI secondary to hypopituitarism (53.2 ± 17.7 years. We evaluated the glycometabolic profile before and 3, 6, 9 and 12 months after dual-release hydrocortisone administration. We also evaluated health-related quality of life, estimated by the AddiQol questionnaire. The mean dose administered of dual-release hydrocortisone was 28.33 ± 6.68 mg/day. Results: One female hypopituitary patient dropped out from the study. After 12 months of treatment, the mean dosage administered of dual-release hydrocortisone was significantly lower (P < 0.05 and all patients reported improved quality of life and well-being. The glycometabolic profile improved and the glycosylated hemoglobin decreased significantly in patients with primary AI (6.25 ± 0.2 vs 5.35 ± 0.17, P < 0.05. In contrast, hypopituitary patients had worse glycometabolic profile and a trend toward hypertriglyceridemia. Conclusions: Dual-release hydrocortisone treatment improved the quality of life of patients with AI, and it allowed a decrease of cortisol dosage administered in the absence of side effects. The glycometabolic profile worsened in hypopituitary patients.

This study examined the intermittent exercise performance and cardiovascular health profile in elite female football players in comparison to untrained young women, as well as a subgroup subjected to football training 2x1 h · week(-1) for 16 weeks. Twenty-seven Danish national team players (elite trained, ET) and 28 untrained women (UT) underwent dual-energy X-ray absorptiometry-scanning (DXA), comprehensive transthoracic echocardiography, treadmill and Yo-Yo Intermittent Endurance level 2 (IE2) testing. Eight women in UT were also tested after the football training period. Maximal oxygen uptake rate (VO2max), peak ventilation and peak lactate were 40, 18 and 51% higher (Pfootball elevated VO2max and Yo-Yo IE2 performance by 16 and 40%, respectively, and lowered fat mass by 6%. Cardiac function was markedly improved by 16 weeks of football training with 26 and 46% increases in TAPSE and E/A ratio, respectively, reaching levels comparable to ET. In summary, elite female football players have a superior cardiovascular health profile and intermittent exercise performance compared to untrained controls, but short-term football training can markedly improve the cardiovascular health status.

In high and upper-middle income countries poly-victimisation (exposure to multiple forms of victimisation) is associated with worse health-related quality of life (HRQoL) among adolescents. There is a lack of empirical evidence about these associations from low- and lower-middle income countries. The aims of this study were to examine the associations between exposure to 1) individual forms of victimisation and 2) poly-victimisation and the HRQoL of adolescents in Vietnam. A cross-sectional, anonymously-completed survey of high school students in Hanoi, Vietnam. Lifetime exposure to eight individual forms of victimisation and poly-victimisation were assessed using the Juvenile Victimisation Questionnaire Revised-2 (JVQ R2). Health-related quality of life was assessed using the Duke Health Profile Adolescent Version (DHP-A). Bi-variate analyses and multiple linear regressions were conducted to assess the associations between individual forms of victimisation, poly-victimisation and HRQoL among girls and boys. In total 1616/1745 students (92.6 %) completed the questionnaire. Adolescent girls had significantly worse HRQoL than boys in all domains, except disability. Different forms of victimisation were associated with different HRQoL domains among girls and boys. Cyber victimisation was the most detrimental to girls' HRQoL while for boys maltreatment was the most detrimental. Experiences of poly-victimisation were associated with worse HRQoL in physical, mental, social and general health, lower levels of self-esteem and increased levels of anxiety, depression and pain domains among both sexes. Among Vietnamese adolescents, experiences of individual forms of victimisation were associated with poorer HRQoL in specific domains; the most detrimental forms of victimisation varied for girls and boys. However, it was experiences of poly-victimisation that had the most detrimental impacts on the HRQoL of both sexes. Recognition of violence, including poly-victimisation, is

The world population has become more globalised with increasing number of people residing in another country for work or other reasons. Little is known about the health profiles of foreign population in Malaysia. The aim of this study was to provide a detailed description of the health problems presented by foreigners attending primary care clinics in Malaysia. Data were derived from the 2012 National Medical Care Survey (NMCS), a cross sectional survey of primary care encounters from public and private primary care clinics sampled from five regions in Malaysia. Patients with foreign nationality were identified and analysed for demographic profiles, reasons for encounter (RFEs), diagnosis, and provision of care. Foreigners accounted for 7.7 % (10,830) of all patient encounters from NMCS. Most encounters were from private clinics (90.2 %). Median age was 28 years (IQR: 24.0, 34.8) and 69.9 % were male. Most visits to the primary care clinics were for symptom-based complaints (69.5 %), followed by procedures (23.0 %) and follow-up visit (7.4 %). The commonest diagnosis in public clinics was antenatal care (21.8 %), followed by high risk pregnancies (7.5 %) and upper respiratory tract infection (URTI) (6.8 %). Private clinics had more cases for general medical examination (13.5 %), URTI (13.1 %) and fever (3.9 %). Medications were prescribed to 76.5 % of these encounters. More foreigners were seeking primary medical care from private clinics and the encounters were for general medical examinations and acute minor ailments. Those who sought care from public clinics were for obstetric problems and chronic diseases. Medications were prescribed to two-thirds of the encounters while other interventions: laboratory investigations, medical procedures and follow-up appointment had lower rates in private clinics. Foreigners are generally of young working group and are expected to have mandatory medical checks. The preponderance of obstetrics seen in public

Radioimmunological investigations of arterial and venous blood from the umbilical cord for 5a-DHP and progesterone were carried out in 60 newly delivered infants using 3 H as a tracer substance. The following findings were revealed: 1) The correlation between progesterone and 5a-DHP was better in the venous blood than in the arterial blood from the umbilical cord and the concentrations measured for the two hormones were higher in the vein. 2) Both the umbilical vein and artery showed more elevated hormone levels in male infants as compared to female infants. 3) The duration of gestation, the concentration of hydrogen ions in the fetal plasma and various other maternal and fetal factors have an influence on the height of the 5a-DHP and progesterone levels in the umbilical blood. This was also concluded from the fact that the (arterial and venous) hormone concentrations measured in infants from primiparae were higher than those in infants from multiparae. The metabolisation of 5a-DHP varies between the sexes, which does not hold true for progosterone. (TRV) [de

Examine relationships between weight-related factors and weight status, body dissatisfaction, chronic health conditions, and quality of life across sexual orientation and gender. Two- and four-year college students participated in the College Student Health Survey (n = 28,703; 2009-2013). Risk differences were calculated to estimate relationships between behavioral profiles and weight status, body satisfaction, diagnosis of a chronic condition, and quality of life, stratified by gender and sexual orientation. Four behavioral profiles, characterized as "healthier eating habits, more physically active," "healthier eating habits," "moderate eating habits," and "unhealthy weight control," were utilized based on latent class analyses, estimated from nine weight-related behavioral survey items. Sexual orientation differences in weight and quality of life were identified. For example, sexual minority groups reported significantly poorer quality of life than their heterosexual counterparts (females: 22.5%-38.6% (sexual minority) vs. 19.8% (heterosexual); males: 14.3%-26.7% (sexual minority) vs. 11.8% (heterosexual)). Compared with the "healthier eating habits, more physically active" profile, the "unhealthy weight control" profile was associated with obesity, poor body satisfaction, and poor quality of life in multiple gender/sexual orientation subgroups. Interventions are needed to address obesity, body dissatisfaction, and poor quality of life among sexual minority college students. © 2016 The Obesity Society.

2004-01-01

Direct hemoperfusion (DHP) with an adsorbent column using polymyxin B-immobilized polystyrene beads has been used to investigate the changes of hemorheology in rabbits with endotoxemia. We measured whole blood viscosity and hemotocrit before and after DHP with polymyxin B-immobilized polystyrene beads. Reduction in blood endotoxin concentration by DHP therapy positively correlated with improvement in hemorheological indexs. Our findings indicate that the amelioration in hemorheology was related directly to endotoxin removal by the adsorbent column with polymyxin B-immobilize polystyrene beads. So DHP with polymyxin B-immobilized polystyrene beads seems to be an important therapeutic strategy for endotoxemia.

Full Text Available Abstract Background The Nottingham Health Profile index of Distress (NHPD has been proposed as a generic undimensional 24-item measure of illness-related distress that is embedded in the Nottingham Health Profile (NHP. Data indicate that the NHPD may have psychometric advantages to the 6-dimensional NHP profile scores. Detailed psychometric evaluations are, however, lacking. Furthermore, to support the validity of the generic property of outcome measures evidence that scores can be interpreted in the same manner in different diagnostic groups are needed. It is currently unknown if NHPD scores have the same meaning across patient populations. This study evaluated the measurement properties and cross-diagnostic validity of the NHPD as a survey instrument among people with Parkinson's disease (PD and peripheral arterial disease (PAD. Methods Data from 215 (PD and 258 (PAD people were Rasch analyzed regarding model fit, reliability, differential item functioning (DIF, unidimensionality and targeting. In cases of cross-diagnostic DIF this was adjusted for and the impact of DIF on the total score and person measures was assessed. Results The NHPD was found to have good overall and individual item fit in both disorders as well as in the pooled sample, but seven items displayed signs of cross-diagnostic DIF. Following adjustment for DIF some aspects of model fit were slightly compromised, whereas others improved somewhat. DIF did not impact total NHPD scores or resulting person measures, but the unadjusted scale displayed minor signs of multidimensionality. Reliability was > 0.8 in all within- and cross-diagnostic analyses. Items tended to represent more distress (mean, 0 logits than that experienced by the sample (mean, -1.6 logits. Conclusion This study supports the within- and cross-diagnostic validity of the NHPD as a survey tool among people with PD and PAD. We encourage others to reassess available NHP data within the NHPD framework to further

2015-01-01

To identify distinct antibody profiles among adults 50-to-74 years old using influenza A/H1N1 HI titers up to 75 days after vaccination. Healthy subjects 50 to 74 years old received the 2010-2011 trivalent inactivated influenza vaccine. We measured venous samples from Days 0, 28, and 75 for HI and VNA and B-cell ELISPOTs. Of 106 subjects, HI titers demonstrated a ceiling effect for 11 or 10% for those with a pre-vaccination HI titer of 1:640 where no subject post-vaccination had an increase in titer. Of the remaining 95 subjects, only 37 or 35% overall had at least a 4-fold increase by Day 28. Of these 37, 3 waned at least 4-fold, and 13 others 2-fold. Thus 15% of the subjects showed waning antibody titers by Day 75. More than half failed to respond at all. The profiles populated by these subjects as defined by HI did not vary with age or gender. The VNA results mimicked the HI profiles, but the profiles for B-cell ELISPOT did not. HI titers at Days 0, 28, and 75 populate 4 biologically plausible profiles. Limitations include lack of consensus for operationally defining waning as well as for the apparent ceiling. Furthermore, though well accepted as a marker for vaccine response, assigning thresholds with HI has limitations. However, VNA closely matches HI in populating these profiles. Thus, we hold that these profiles, having face- and content-validity, may provide a basis for understanding variation in genomic and transcriptomic response to influenza vaccination in this age group.

Full Text Available This Short Communication builds on recent findings that documented an anomaly in the education–health gradient: adults who attended college but did not earn a BA (the subbaccalaureate group reported an equal or higher level of health problems than adults with high school (HS diploma. Our aim is to test whether this anomaly holds when we eliminate potential reporting differences, by examining biomarker levels in the subbaccalaureate vs HS groups.Using the restricted 1999–2012 NHANES, we estimate models of biomarkers for cardiovascular and metabolic diseases as a function of educational attainment, including three subbaccalaureate levels: “some college”, vocational associate degree (AA, and academic AA.The data show that adults with “some college” or vocational AA have no systematic advantage over HS graduates in most biomarker indices while academic AA is associated with a significantly better risk profile compared to HS. The findings indicate that the adults with some college and vocational AA degrees do not benefit from their college experience in terms of improved physiological risk profile.This pattern underscores the need to understand and explain the anomalous health pattern that concerns 28% of American adults in the subbaccalaureate group among whom many reap little health payoffs to postsecondary schooling.

Continuing education (CE) can support health care professionals in maintaining and developing their knowledge and competencies. Although lack of motivation is one of the most important barriers of pharmacists' participation in CE, we know little about the quality or the quantity of motivation. We used the self-determination theory, which describes autonomous motivation (AM) as originating from within an individual and controlled motivation (CM) as originating from external factors, as a framework for this study. Our aim was to obtain insight into the quality and quantity of pharmacists' motivation for CE. The scores of 425 pharmacists on Academic Motivation Scale were subjected to K-means cluster analysis to generate motivational profiles. We unraveled four motivational profiles: (1) good quality with high AM/low CM, (2) high quantity with high AM/high CM, (3) poor quality with low AM/high CM, and (4) low quantity with low AM/low CM. Female pharmacists, pharmacists working in a hospital pharmacy, pharmacists working for more than 10 years, and pharmacists not in training were highly represented in the good-quality profile. Pharmacists working in a community pharmacy, pharmacists working for less than 10 years, and pharmacists in training were highly represented in the high-quantity profile. Male pharmacists were more or less equally distributed over the four profiles. The highest percentage of pharmacy owners was shown in the low-quantity profile, and the highest percentage of the nonowners was shown in the good-quality profile. Pharmacists exhibit different motivational profiles, which are associated with their background characteristics, such as gender, ownership of business, practice setting, and current training. Motivational profiles could be used to tailor CE courses for pharmacists.

FERNANDA DOS SANTOS

Full Text Available ABSTRACT Objective: to analyze the profile of appendectomies performed in the Brazilian Public Health System (SUS and to compare the laparoscopic and laparotomic techniques of appendectomy. Methods: This work used information from DataSus from 2008 to 2014 (http://datasus.saude.gov.br. We compared the data of patients submitted to laparotomic appendectomy with those submitted to laparoscopic one. Results: when comparing the total growth of appendectomies, the laparoscopic route increased 279.7%, while the increase in laparotomic surgery was 25% (p <0.001 in the study period. With regard to medical and hospital costs, laparoscopic appendectomy accounted for only 2.6% of the total expenditure on appendectomies performed by the Unified Health System (SUS hospitals, with an average cost 7.6% lower than that of laparotomy procedures, but without statistical significance. The mortality rate was 57.1% lower in the laparoscopic approach when compared with laparotomy. Conclusion: there has been a significant increase in the laparoscopic route in the treatment of appendicitis, but the method is still rarely used in SUS patients. The costs of laparoscopic appendectomy were similar to those observed in laparotomic access.

IHE XDS-I profile proposes an architecture model for cross-enterprise medical image sharing, but there are only a few clinical implementations reported. Here, we investigate three pilot studies based on the IHE XDS-I profile to see whether we can use this architecture as a foundation for image sharing solutions in a variety of health-care settings. The first pilot study was image sharing for cross-enterprise health care with federated integration, which was implemented in Huadong Hospital and Shanghai Sixth People's Hospital within the Shanghai Shen-Kang Hospital Management Center; the second pilot study was XDS-I-based patient-controlled image sharing solution, which was implemented by the Radiological Society of North America (RSNA) team in the USA; and the third pilot study was collaborative imaging diagnosis with electronic health-care record integration in regional health care, which was implemented in two districts in Shanghai. In order to support these pilot studies, we designed and developed new image access methods, components, and data models such as RAD-69/WADO hybrid image retrieval, RSNA clearinghouse, and extension of metadata definitions in both the submission set and the cross-enterprise document sharing (XDS) registry. We identified several key issues that impact the implementation of XDS-I in practical applications, and conclude that the IHE XDS-I profile is a theoretically good architecture and a useful foundation for medical image sharing solutions across multiple regional health-care providers.

Sea worm, Amphitrite ornata, has evolved its globin (an O₂ carrier) also to serves as a dehaloperoxidase (DHP) to detoxify haloaromatic pollutants generated by competing species. A previous mutagenesis study by our groups on both DHP and sperm whale myoglobin (SW Mb) revealed some structural factors that influence the dehaloperoxidase activities (significantly lower for Mb) of both proteins. Using an isocyanide/O₂ partition constant measurement method in this study, we have examined the effects of these structural factors on the O₂ equilibrium constants (K_O2) of DHP, SW Mb, and their mutants. A clear trend of decreasing O₂ affinity and increasing catalytic activity along with the increase in the distal His N^ε–heme iron distance is observed. An H93K/T95H Mb double mutant mimicking the DHP proximal His positioning exhibited markedly enhanced O₂ affinity, confirming the essential effect of proximal His rotation on the globin function of DHP. For DHP, the L100F, T56G and M86E variants showed the effects of distal volume, distal His flexibility and proximal electronic push, respectively, on the O₂ affinity. This study provides insights into how DHP has evolved its heme environment to gain significantly enhanced peroxidase capability without compromising its primary function as an O₂ carrier.

As the seed of Zizyphus jujuba var. spinosa (Bunge) Hu ex H.F. Chow (Rhamnaceae) has been used to sleep disturbances in traditional Chinese and Korean medicine, many previous studies have focused on its sedative effect. Recently, we reported the neuroprotective effect of the effect of Z. jujuba var. spinosa. However, its effects on synaptic function have not yet been studied. In this project, we examined the action of ethanol extract of the seed of Z. jujuba var. spinosa (DHP1401) on synaptic transmission in the hippocampus. To investigate the effects of DHP1401, field recordings were conducted using hippocampal slices (400µm). Object recognition test was introduced to examine whether DHP1401 affect normal recognition memory. DHP1401 (50μg/ml) induced a significant increase in synaptic activity in Shaffer collateral pathway in a concentration-dependent manner. This increase of synaptic responses was blocked by NBQX, a broad spectrum α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor antagonist, but not IEM-1460, a Ca 2+ -permeable AMPAR blocker. Moreover, U0126, a mitogen-activated protein kinase inhibitor, SQ22536, an adenylyl cyclase inhibitor, and PKI, a protein kinase A inhibitor, blocked DHP1401-induced increase in synaptic transmission. Finally, DHP1401 facilitated object recognition memory. These results suggest that DHP1401 increase synaptic transmission through increase of synaptic AMPAR transmission via MAPK, AC and PAK.

Recent theories suggest that behavioural addictions and substance use disorders may be the result of the same underlying vulnerability. The present study investigates profiles of family background, personality and mental health factors and their associations with seven behavioural addictions (to the internet, gaming, smartphones, internet sex, gambling, exercise and work) and three substance use disorder scales (for alcohol, cannabis and tobacco). The sample consisted of 5287 young Swiss men (mean age = 25.42) from the Cohort Study on Substance Use Risk Factors (C-SURF). A latent profile analysis was performed on family background, personality and mental health factors. The derived profiles were compared with regards to means and prevalence rates of the behavioural addiction and substance use disorder scales. Seven latent profiles were identified, ranging from profiles with a positive family background, favourable personality patterns and low values on mental health scales to profiles with a negative family background, unfavourable personality pattern and high values on mental health scales. Addiction scale means, corresponding prevalence rates and the number of concurrent addictions were highest in profiles with high values on mental health scales and a personality pattern dominated by neuroticism. Overall, behavioural addictions and substance use disorders showed similar patterns across latent profiles. Patterns of family background, personality and mental health factors were associated with different levels of vulnerability to addictions. Behavioural addictions and substance use disorders may thus be the result of the same underlying vulnerabilities. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

India, the second most populated country of the world with a population of 1.027 billion, is a country of contrasts. It is characterized as one of the world's largest industrial nations, yet most of the negative characteristics of poor and developing countries define India too. The population is predominantly rural, and 36% of people still live below poverty line. There is a continuous migration of rural people into urban slums creating major health and economic problems. India is one of the pioneer countries in health services planning with a focus on primary health care. Improvement in the health status of the population has been one of the major thrust areas for social development programmes in the country. However, only a small percentage of the total annual budget is spent on health. Mental health is part of the general health services, and carries no separate budget. The National Mental Health Programme serves practically as the mental health policy. Recently, there was an eight-fold increase in budget allocation for the National Mental Health Programme for the Tenth Five-Year Plan (2002-2007). India is a multicultural traditional society where people visit religious and traditional healers for general and mental health related problems. However, wherever modern health services are available, people do come forward. India has a number of public policy and judicial enactments, which may impact on mental health. These have tried to address the issues of stigma attached to the mental illnesses and the rights of mentally ill people in society. A large number of epidemiological surveys done in India on mental disorders have demonstrated the prevalence of mental morbidity in rural and urban areas of the country; these rates are comparable to global rates. Although India is well placed as far as trained manpower in general health services is concerned, the mental health trained personnel are quite limited, and these are mostly based in urban areas. Considering this

UK social firms are under-researched but are a potentially important vocational option for people with mental health problems. To describe the clinical profile, satisfaction levels and experiences of social firms employees with mental health problems. Clinical, work and service use characteristics were collected from social firms' employees with mental health problems in England and Wales. Workplace experience and satisfaction were explored qualitatively. Predominantly, social firms' employees (N = 80) report that they have a diagnosis of depression (56%) and anxiety (41%). People with schizophrenia (20%) or bipolar disorder (5%) were a minority. Respondents had low symptom and disability levels, high quality of life and job satisfaction and experienced reductions in secondary mental health service use over time. High-workplace satisfaction was related to flexibility, manager and colleague support and workplace accommodations. The clinical profile, quality of life and job satisfaction level of employees with mental health problems suggest social firms could be a useful addition to UK vocational services for some people. Current employees mainly have common mental disorders, and social firms will need to shift their focus if they are to form a substantial pathway for the vocational recovery of people currently using community mental health teams.

Millions of low-income people of diverse ethnicities inhabit stressful old urban industrial neighborhoods. Yet we know little about the health impacts of built-environment stressors and risk perceptions in such settings; we lack even basic health profiles. Difficult access is one reason (it took us 30 months to survey 80 households); the lack of multifaceted survey tools is another. We designed and implemented a pilot vulnerability assessment tool in Worcester, Massachusetts. We answer: (1) H...

To examine the association of favorable cardiovascular health (CVH) status with 1-year health care expenditures and resource utilization in a large health care employee population. Employees of Baptist Health South Florida participated in a health risk assessment from January 1 through September 30, 2014. Information on dietary patterns, physical activity, blood pressure, blood glucose level, total cholesterol level, and smoking were collected. Participants were categorized into CVH profiles using the American Heart Association's ideal CVH construct as optimal (6-7 metrics), moderate (3-5 metrics), and low (0-2 metrics). Two-part econometric models were used to analyze health care expenditures. Of 9097 participants (mean ± SD age, 42.7±12.1 years), 1054 (11.6%) had optimal, 6945 (76.3%) had moderate, and 1098 (12.1%) had low CVH profiles. The mean annual health care expenditures among those with a low CVH profile was $10,104 (95% CI, $8633-$11,576) compared with $5824 (95% CI, $5485-$6164) and $4282 (95% CI, $3639-$4926) in employees with moderate and optimal CVH profiles, respectively. In adjusted analyses, persons with optimal and moderate CVH had a $2021 (95% CI, -$3241 to -$801) and $940 (95% CI, -$1560 to $80) lower mean expenditure, respectively, than those with low CVH. This trend remained even after adjusting for demographic characteristics and comorbid conditions as well as across all demographic subgroups. Similarly, health care resource utilization was significantly lower in those with optimal CVH profiles compared with those with moderate or low CVH profiles. Favorable CVH profile is associated with significantly lower total medical expenditures and health care utilization in a large, young, ethnically diverse, and fully insured employee population.

Zajacova, Anna; Johnson-Lawrence, Vicki

2016-12-01

This Short Communication builds on recent findings that documented an anomaly in the education-health gradient: adults who attended college but did not earn a BA (the subbaccalaureate group) reported an equal or higher level of health problems than adults with high school (HS) diploma. Our aim is to test whether this anomaly holds when we eliminate potential reporting differences, by examining biomarker levels in the subbaccalaureate vs HS groups. Using the restricted 1999-2012 NHANES, we estimate models of biomarkers for cardiovascular and metabolic diseases as a function of educational attainment, including three subbaccalaureate levels: "some college", vocational associate degree (AA), and academic AA. The data show that adults with "some college" or vocational AA have no systematic advantage over HS graduates in most biomarker indices while academic AA is associated with a significantly better risk profile compared to HS. The findings indicate that the adults with some college and vocational AA degrees do not benefit from their college experience in terms of improved physiological risk profile. This pattern underscores the need to understand and explain the anomalous health pattern that concerns 28% of American adults in the subbaccalaureate group among whom many reap little health payoffs to postsecondary schooling.

People with intellectual disability are a minority group who experience poorer physical and mental health than the general population and have difficulty accessing healthcare services. There is lack of knowledge about healthcare service needs and gaps experienced by people with intellectual disability. This study aims to interrogate a large linked administrative data set containing hospital admissions, presentations to emergency departments (ED) and mortality data to provide evidence to inform the development of improved health and mental health services for this population. A retrospective cohort of people with intellectual disability (n=51 452) from New South Wales (NSW), Australia, to explore health and mental health profiles, mortality, pattern of health service use and associated costs between 2005 and 2013. The cohort is drawn from: the Disability Services Minimum Data Set; Admitted Patients Data Collection; Emergency Department Data Collection, Australian Bureau of Statistics Death Registry and Registry of Births, Deaths and Marriages. Mental health service usage among those with intellectual disability will be compared to a cohort of people who used mental health services (n=1 073 139) and service usage other than for mental health will be compared with published data from the general population. The median age of the cohort was 24 at the time of the last hospital admission and 21 at the last ED presentation. The cohort has a higher proportion of men than women and accounts for 0.6% of the NSW population in 2011. Over 70% had up to 5 ED presentations and hospitalisations between 2005 and 2012. A high proportion of people with intellectual disability live in the most disadvantaged neighbourhoods. Results will be used to inform the development of more responsive healthcare, including improved interactions between health, social and disability supports. More generally, the results will assist the development of more inclusive policy frameworks for people

Full Text Available This study aims to verify the epidemiological profile of the pregnant women attending the Basic Health Unit (BHU of the Jardim Botânico in Sinop Mato Grosso, who presented the probable date of delivery until January 2017. Tracing the epidemiological profile of pregnant women, we hope to obtain pertinent information to identify possible gestational problems, to list their social conditions that may negatively influence pregnancy, to identify possible gestational risk factors and to identify the main complaints of this population. The research has a descriptive profile, with quantitative and qualitative approach. Twenty women, aged 18 years and over, regardless of their obstetric history, were treated at BHU Jardim Botânico, who were registered at Sispré-natal and who agreed to participate in the study. Pregnant women under the age of 18 years, who are not registered in Sispré-natal, and those who are not willing to participate in the survey were excluded. Data collection was done through a structured questionnaire with closed and open questions, being performed individually or with the companion's company during pre-scheduled interviews that were performed at the health unit or at a place indicated by the pregnant woman. The quantitative data obtained during the study were analyzed, structured in spreadsheets and graphs through the programs Microsoft Office Excel and Word 2010, and the qualitative data were analyzed and distributed in categories according to Bardin method. To begin the data collection, the Ethics Committee of the Institution was requested in accordance with Resolution 466/2012 of the National Health Council.

Previous research suggests that childhood maltreatment is associated with the onset of eating disorders (ED). In turn, EDs are associated with alternative psychopathologies such as depression and posttraumatic stress disorder (PTSD), and with suicidality. Moreover, it has been reported that various ED profiles may exist. The aim of the current study was to examine the profiles of disordered eating and the associations of these with childhood maltreatment and with mental health psychopathology. The current study utilised a representative sample of English females (N = 4206) and assessed for the presence of disordered eating profiles using Latent Class Analysis. Multinomial logistic regression was implemented to examine the associations of childhood sexual and physical abuse with the disordered eating profiles and the associations of these with PTSD, depression and suicidality. Results supported those of previous findings in that we found five latent classes of which three were regarded as disordered eating classes. Significant relationships were found between these and measures of childhood trauma and mental health outcomes. Childhood sexual and physical abuse increased the likelihood of membership in disordered eating classes and these in turn increased the likelihood of adverse mental health and suicidal outcomes.

Chronic headache is common among patients in neurology clinics. Patients may suffer important economic and social losses because of headaches, which may result in high expectations for treatment outcomes. When their treatment goals are not reached quickly, treatment may be difficult to maintain and patients may consult with numerous health professionals. This retrospective study evaluated the relationship between treatment and the profiles of previous health professionals consulted by patients in a tertiary headache center. The records were reviewed of all patients from a headache center who were seen in initial consultation between January 2000 and June 2003. Data related to patient demographic characteristics (sex and age), headache diagnosis, and the profile (quality and quantity) of previous healthcare consultations exclusively related to headache, were collected. The headache diagnoses were confirmed according to the IHS criteria (1988) and to the Silberstein criteria (1994,1996). Although adherence includes taking the prescribed medicines, discontinuing overused symptomatic medications, and changing behavior, among other things, for this study, adherence was defined as when the patient returned at least 2 times within a 3- to 3.5-month period. Patients were separated into groups depending on the number of different healthcare professionals they had consulted, from none to more than 7. Data from 495 patients were analyzed; 357 were women and 138 were men (ages 6 to 90 years; mean, 41.1 +/- 15.05 years). The headache diagnoses included migraine without aura (43.2%), chronic (transformed) migraine (40%), cluster headache (6.5%), episodic tension-type headache (0.8%), and hemicrania continua (0.4%). The 24.2% of patients who sought care from no more than 1 health professional showed a 59.8% adherence rate; 29% of the total had consulted 7 or more health professionals and showed an adherence rate of 74.3% (P = .0004). In Brazil, the belief is widespread that

The PROMIS-29 v2.0 profile assesses pain intensity using a single 0-10 numeric rating item and seven health domains (physical function, fatigue, pain interference, depressive symptoms, anxiety, ability to participate in social roles and activities, and sleep disturbance) using four items per domain. This paper describes the development of physical and mental health summary scores for the PROMIS-29 v2.0. We conducted factor analyses of PROMIS-29 scales on data collected from two internet panels (n = 3000 and 2000). Confirmatory factor analyses provided support for a physical health factor defined by physical function, pain (interference and intensity), and ability to participate in social roles and activities, and a mental health factor defined primarily by emotional distress (anxiety and depressive symptoms). Reliabilities for these two summary scores were 0.98 (physical health) and 0.97 (mental health). Correlations of the PROMIS-29 v2.0 physical and mental health summary scores with chronic conditions and other health-related quality of life measures were consistent with a priori hypotheses. This study develops and provides preliminary evidence supporting the reliability and validity of PROMIS-29 v2.0 physical and mental health summary scores that can be used in future studies to assess impacts of health care interventions and track changes in health over time. Further evaluation of these and alternative summary measures is recommended.

The food industry holds great potential for driving consumers to adopt healthy food choices as (re)formulation of foods can improve the nutritional quality of these foods. Reformulation has been identified as a cost-effective intervention in addressing non-communicable diseases as it does not require significant alterations of consumer behaviour and dietary habits. Nutrient profiling (NP), the science of categorizing foods based on their nutrient composition, has emerged as an essential tool and is implemented through many different profiling systems to guide reformulation and other nutrition policies. NP systems should be adapted to their specific purposes as it is not possible to design one system that can equally address all policies and purposes, e.g. reformulation and labelling. The present paper discusses some of the key principles and specificities that underlie a NP system designed for reformulation with the example of the Nestlé nutritional profiling system. Furthermore, the impact of reformulation at the level of the food product, dietary intakes and public health are reviewed. Several studies showed that food and beverage reformulation, guided by a NP system, may be effective in improving population nutritional intakes and thereby its health status. In order to achieve its maximum potential and modify the food environment in a beneficial manner, reformulation should be implemented by the entire food sector. Multi-stakeholder partnerships including governments, food industry, retailers and consumer associations that will state concrete time-bound objectives accompanied by an independent monitoring system are the potential solution.

Full Text Available OBJECTIVES: To analyze the dietary profile of participants who used two health promotion services located in socially vulnerable areas in a Brazilian metropolis. METHODS: A cross-sectional comparative study was conducted with participants (n = 370 aged ≥ 20 years who joined two services of the Academias da Cidade program in Belo Horizonte, Minas Gerais, Brazil. The study participants engaged in physical activity and nutritional education actions directed by the services from 2009 to 2010. The sociodemographic and economic conditions and health and nutrition profiles of each individual were assessed. RESULTS: Participants from a high social-risk who used the service did not demonstrate adequate intake of vegetables (54.6 versus 43.6%; p = 0.038, sweets (33.5 versus 23.2%; p = 0.030, soft drinks (28.5 versus 11.9%; p < 0.001, artificial juice (34.7 versus 22.6%; p = 0.011, and processed meat (48.8 versus 32.7; p = 0.002. However, in the other service, lower social vulnerability, a higher prevalence of abdominal adiposity (60.7 versus 43.0%; p = 0.004 and consumption of high-fat meat products (53.0 versus 36.5%; p = 0.002 was observed. CONCLUSION: Participants who used both services demonstrated inadequate food intake compatible with the development of chronic disease profiles. However, the participants in each service were distinct from each other. This suggests that promotion of healthy eating should to contemplate the territory and its interface with people health.

'Changing climate, changing health, changing stories' profile: using an EcoHealth approach to explore impacts of climate change on inuit health.

Global climate change and its impact on public health exemplify the challenge of managing complexity and uncertainty in health research. The Canadian North is currently experiencing dramatic shifts in climate, resulting in environmental changes which impact Inuit livelihoods, cultural practices, and health. For researchers investigating potential climate change impacts on Inuit health, it has become clear that comprehensive and meaningful research outcomes depend on taking a systemic and transdisciplinary approach that engages local citizens in project design, data collection, and analysis. While it is increasingly recognised that using approaches that embrace complexity is a necessity in public health, mobilizing such approaches from theory into practice can be challenging. In 2009, the Rigolet Inuit Community Government in Rigolet, Nunatsiavut, Canada partnered with a transdisciplinary team of researchers, health practitioners, and community storytelling facilitators to create the Changing Climate, Changing Health, Changing Stories project, aimed at developing a multi-media participatory, community-run methodological strategy to gather locally appropriate and meaningful data to explore climate-health relationships. The goal of this profile paper is to describe how an EcoHealth approach guided by principles of transdisciplinarity, community participation, and social equity was used to plan and implement this climate-health research project. An overview of the project, including project development, research methods, project outcomes to date, and challenges encountered, is presented. Though introduced in this one case study, the processes, methods, and lessons learned are broadly applicable to researchers and communities interested in implementing EcoHealth approaches in community-based research.

This study examined characteristics and profiles of youth receiving services in 1 of Florida's Medicaid-funded residential mental health treatment programs--State Inpatient Psychiatric Program (SIPP)--between July 1, 2004, and June 30, 2008 (N=1,432). Latent class analysis (LCA) was used to classify youth, and 3 classes were identified: Children With Multiple Needs, Children With No Caregivers, and Abused Children With Substantial Maltreatment History. The results of LCA showed that Children With Multiple Needs experienced the greatest risk for adverse outcomes. Compared with youth in the other 2 classes, these children were more likely to get readmitted to SIPP, more likely to become involved with the juvenile justice system, and more likely to experience involuntary mental health assessments. Implications of the findings are discussed. PsycINFO Database Record (c) 2014 APA, all rights reserved

Are home nurses (also known as community nurses) ready for their changing role in primary care? A quantitative study was performed in home nursing in Flanders, Belgium, to explore the activity profile of home nurses and health care assistants, using the 24-hour recall instrument for home nursing. Seven dates were determined, covering each day of the week and the weekend, on which data collection would take place. All the home nurses and health care assistants from the participating organisations across Flanders were invited to participate in the study. All data were measured at nominal level. A total of 2478 home nurses and 277 health care assistants registered 336 128 (47 977 patients) and 36 905 (4558 patients) activities, respectively. Home nurses and health care assistants mainly perform 'self-care facilitation' activities in combination with 'psychosocial care' activities. Health care assistants also support home nurses in the 'selfcare facilitation' of patients who do not have a specific nursing indication.

Mindfulness and Psychological Health Outcomes: A Latent Profile Analysis among Military Personnel and College Students.

Previous research on trait mindfulness facets using person-centered analyses (e.g., latent profile analysis [LPA]) has identified four distinct mindfulness profiles among college students: a high mindfulness group (high on all facets of the Five-Factor Mindfulness Questionnaire [FFMQ]), a judgmentally observing group (highest on observing, but low on non-judging of inner experience and acting with awareness), a non-judgmentally aware group (high on non-judging of inner experience and acting with awareness, but very low on observing), and a low mindfulness group (low on all facets of the FFMQ). In the present study, we used LPA to identify distinct mindfulness profiles in a community based sample of U.S. military personnel (majority veterans; n = 407) and non-military college students ( n = 310) and compare these profiles on symptoms of psychological health outcomes (e.g., suicidality, PTSD, anxiety, rumination) and percentage of participants exceeding clinically significant cut-offs for depressive symptoms, substance use, and alcohol use. In the subsample of college students, we replicated previous research and found four distinct mindfulness profiles; however, in the military subsample we found three distinct mindfulness profiles (a combined low mindfulness/judgmentally observing class). In both subsamples, we found that the most adaptive profile was the "high mindfulness" profile (i.e., demonstrated the lowest scores on all psychological symptoms and the lowest probability of exceeding clinical cut-offs). Based on these findings, we purport that the comprehensive examination of an individual's mindfulness profile could help clinicians tailor interventions/treatments that capitalize on individual's specific strengths and work to address their specific deficits.

Mental health issue was a serious matter that was often neglected by people. This article will describe a study of the mental health profile among the learners of Malaysia Technical University (MTU) that focus on Universiti Tun Hussein Onn Malaysia (UTHM). A survey using DASS-21 inventory and self-developed questionnaire was used for this study to investigate learners’ mental health level in three elements and factors contribute towards mental health. A total number of 450 students from seven faculties in UTHM was strata randomly selected as sampel for this study. The relationships between factors of mental health and the elements of mental health was identified. Collected data was analysed using percentage, mean score, standard deviation and multiple linear regression. Findings showed that majority of students possess normal level but the percentage of severe and extremely severe level was increasing. The main factor highly significantly correlate to all the mental health elements was self-evaluation. Hence, it is highly recommended that mental health issue needs great attention and remedial action from higher learning institution, non-governmental organizations, parents, students themselves and other concerned bodies.

Treatment with progesterone protects the male and female brain against damage after middle cerebral artery occlusion (MCAO). However, in both sexes, the brain contains significant amounts of endogenous progesterone. It is not known whether endogenously produced progesterone enhances the resistance of the brain to ischemic insult. Here, we used steroid profiling by gas chromatography-tandem mass spectrometry (GC-MS/MS) for exploring adaptive and sex-specific changes in brain levels of progesterone and its metabolites after MCAO. We show that, in the male mouse brain, progesterone is mainly metabolized via 5α-reduction leading to 5α-dihydroprogesterone (5α-DHP), also a progesterone receptor (PR) agonist ligand in neural cells, then to 3α,5α-tetrahydroprogesterone (3α,5α-THP). In the female mouse brain, levels of 5α-DHP and 3α,5α-THP are lower and levels of 20α-DHP are higher than in males. After MCAO, levels of progesterone and 5α-DHP are upregulated rapidly to pregnancy-like levels in the male but not in the female brain. To assess whether endogenous progesterone and 5α-DHP contribute to the resistance of neural cells to ischemic damage, we inactivated PR selectively in the CNS. Deletion of PR in the brain reduced its resistance to MCAO, resulting in increased infarct volumes and neurological deficits in both sexes. Importantly, endogenous PR ligands continue to protect the brain of aging mice. These results uncover the unexpected importance of endogenous progesterone and its metabolites in cerebroprotection. They also reveal that the female reproductive hormone progesterone is an endogenous cerebroprotective neurosteroid in both sexes. SIGNIFICANCE STATEMENT The brain responds to injury with protective signaling and has a remarkable capacity to protect itself. We show here that, in response to ischemic stroke, levels of progesterone and its neuroactive metabolite 5α-dihydroprogesterone are upregulated rapidly in the male mouse brain but not in the

To describe the health, treatment and health care resources consumption profile among Spanish adults with diabetes and chronic obstructive pulmonary disease (COPD), and compare it with that of non-diabetic COPD patients. An observational and descriptive epidemiological study (EPIDEPOC study). The study included patients with stable COPD and aged > or =40 years, evaluated in primary care. Data were collected relating to sociodemographic variables, health profile, quality of life (SF-12), treatment and health care resources consumption. The results corresponding to diabetic and non-diabetic patients were compared. A total of 10,711 patients (75.6% males) with COPD were evaluated. The prevalence of diabetes was 16.9%. The diabetic patients were significantly older, with a larger percentage of women, and a lesser educational level compared with the non-diabetic patients. In addition, the diabetics were more sedentary, smoked less, and presented a higher percentage of obesity (33.6% versus 19.7%) than the non-diabetic patients. The severity of airways obstruction was greater among the diabetics than in the non-diabetic patients (54.57+/-13.37% versus 57.92+/-13.39%, respectively, pconsumption of drugs for COPD. In addition, they consumed significantly more health care (and thus economical) resources than the non-diabetic patients. The results of the multivariate logistic regression analysis showed that the variables that were independently associated to COPD among diabetic patients were: higher age, higher BMI, concomitant chronic heart disease, use of inhaled corticoids, SF-12 mental component, SF-12 physical component and total cost of COPD. The presence of diabetes in patients with COPD shows in the bivariate analysis a more severe lung disease, greater co-morbidity, poorer quality of life, and a greater consumption of resources, as well as a less favorable course in the previous year. However, the multivariate logistic regression shows that the variables that are

Full Text Available Sex steroid hormones have neuroprotective properties which may be mediated by brain-derived neurotrophic factor (BDNF. This study sought to determine the interactive effects of preadolescent hormone manipulation and BDNF heterozygosity (+/− on hippocampal NMDA-R expression. Wild-type and BDNF+/− mice were gonadectomised, and females received either 17β-estradiol or progesterone treatment, while males received either testosterone or dihydrotestosterone (DHT treatment. Dorsal (DHP and ventral hippocampus (VHP were dissected, and protein expression of GluN1, GluN2A, GluN2B, and PSD-95 was assessed by Western blot analysis. Significant genotype × OVX interactions were found for GluN1 and GluN2 expression within the DHP of female mice, suggesting modulation of select NMDA-R levels by female sex hormones is mediated by BDNF. Furthermore, within the DHP BDNF+/− mice show a hypersensitive response to hormone treatment on GluN2 expression which may result from upstream alterations in TrkB phosphorylation. In contrast to the DHP, the VHP showed no effects of hormone manipulation but significant effects of genotype on NMDA-R expression. Castration had no effect on NMDA-R expression; however, androgen treatment had selective effects on GluN2B. These data show case distinct, interactive roles for sex steroid hormones and BDNF in the regulation of NMDA-R expression that are dependent on dorsal versus ventral hippocampal region.

The aim of the present study was to assess the effects of subclinical inflammation on specific humoral immunity in dogs vaccinated with Nobivac® DHP based on serum levels of CRP and Hp. Dogs from the group I were administered Nobivac® DHP, the vaccine against distemper, infectious hepatitis and parvovirus whereas group II animals received subcutaneous turpentine oil to induce subclinical inflammation, followed by Nobivac® DHP after 24 h. Animals in group III received only turpentine oil in the way and amount identical to that as in group II. Nobivac DHP relatively poorly induced the immune inflammatory response showing good immunogenic properties, which was evidenced by only a double increase in mean CRP and Hp levels associated with antigenic stimulation in group I. In group II, serum neutralization (SN) and haemagglutination inhibition (HI) results were quite closely correlated with serum levels of CPR and Hp. Our findings suggest that the efficacy of vaccinations in dogs can be significantly affected by subclinical inflammations, which is indicated by a correlation between serum CRP and Hp levels versus antibody titres for canine distemper and parvovirus in both experimental groups of dogs (group I and II). The correlation of mean CRP and Hp values in dogs with subclinical inflammation and after vaccination with the kinetics of increasing antibody titres against distemper and parvovirus in group II dogs reflects the severity of inflammatory response and the extent of specific humoral immunity. Routine determinations of serum CRP and Hp levels as the indices of inflammation severity can be the essential biochemical markers for assessment of dogs' health in the period preceding specific immunoprophylaxis and efficacy of the vaccine.

Objectives Early identification of distinct patterns of child social–emotional strengths and vulnerabilities has the potential to improve our understanding of child mental health and well-being; however, few studies have explored natural groupings of indicators of child vulnerability and strengths at a population level. The purpose of this study was to examine heterogeneity in the patterns of young children's social and emotional health and investigate the extent to which sociodemographic characteristics were associated. Design Cross-sectional study based on a population-level cohort. Setting All kindergarten children attending public schools between 2004 and 2007 in British Columbia (BC), Canada. Participants 35 818 kindergarten children (age of 5 years) with available linked data from the Early Development Instrument (EDI), BC Ministry of Health and BC Ministry of Education. Outcome measure We used latent profile analysis (LPA) to identify distinct profiles of social–emotional health according to children's mean scores across eight social–emotional subscales on the EDI, a teacher-rated measure of children's early development. Subscales measured children's overall social competence, responsibility and respect, approaches to learning, readiness to explore, prosocial behaviour, anxiety, aggression and hyperactivity. Results Six social–emotional profiles were identified: (1) overall high social–emotional functioning, (2) inhibited-adaptive (3) uninhibited-adaptive, (4) inhibited-disengaged, (5) uninhibited-aggressive/hyperactive and (6) overall low social–emotional functioning. Boys, children with English as a second language (ESL) status and children with lower household income had higher odds of membership to the lower social–emotional functioning groups; however, this association was less negative among boys with ESL status. Conclusions Over 40% of children exhibited some vulnerability in early social–emotional health, and profiles were

The Tore Supra polarimeter used to measure the poloidal field distribution is described. The current density profiles are computed in two different ways using the interferometric and polarimetric data in conjunction with the magnetic data and the location of the inversion radius determined by the soft X-ray camera. The current density inside the q=1 surface is investigated for normal and monster sawteeth. Its variation are also measured by the polarimeter and compared with that predicted by the current diffusion equation assuming complete reconnection. Finally, the safety factor profile is compared with that obtained with the striation data of the pellet ablation. The results of the evolution of the q profile during sawteeth are in good agreement with those obtained in other devices. (author) 9 refs.; 4 figs

Risk Profile in a Sample of Patients with Breast Cancer from the Public Health Perspective

Full Text Available Cancer represents a major public health and economical burden in developed countries and has emerged as a major public health problem in developing countries, matching its effect in industrialized nations. Although there have been recent declines in breast cancer mortality rates in some European Union countries, breast cancer remains of key importance to public health in Europe. Now days there is increasing recognition of the causative role of lifestyle factors, as smoking, diet, alcohol consumption, or lake of physical activity. The present study aimed to appreciate the presence and magnitude of modifiable risk factors for breast cancer in a sample of patients diagnosed with the disease, and to outline a risk profile liable to be changed in the intention of reducing the global risk. Risk factors have been investigated in 65 patients diagnosed with breast cancer using a questionnaire for breast cancer risk factors evaluation. The high risk profile was identified as taking shape for urban environment, modulated by the impact of overweight-obesity, smoking, reproductive factors and environmental exposure to different chemical substances. From the public health perspective, the control of overweight and obesity comes out in the foreground of preventive activities. Public health approaches emphasize on inexpensive, practical methods and in this perspective the approach of obesity should focus on the alteration of environmental context, promoting healthy eating and increased physical activity which could have a positive, independent impact on breast cancer risk

Practice guidelines advocate combining pharmacotherapy with lifestyle counseling for patients with hypertension. To allow for appropriate tailoring of interventions to meet individual patient needs, a comprehensive understanding of baseline patient characteristics is essential. However, few studies have empirically assessed behavioral profiles of hypertensive patients in Web-based lifestyle counseling programs. The objectives of this study were to (1) specify baseline psychobehavioral profiles of patients with hypertension who were enrolled in a Web-based lifestyle counseling trial, and (2) examine mean differences among the identified profile groups in demographics, psychological distress, self-reported self-care behaviors, physiological outcomes, and program engagement to determine prognostic implications. Participants (N=264; mean age 57.5 years; 154/264, 58.3% female; 193/264, 73.1% white) were recruited into a longitudinal, double-blind, randomized controlled trial, designed to evaluate an online lifestyle intervention for hypertensive patients. A series of latent profile analyses identified psychobehavioral profiles, indicated by baseline measures of mood, motivation, and health behaviors. Mean differences between profile groups were then explored. A 2-class solution provided the best model fit (the Bayesian information criterion (BIC) is 10,133.11; sample-size adjusted BIC is 10,006.54; Lo-Mendell-Rubin likelihood ratio test is 65.56, P=.001). The 2 profile groups were (1) adaptive adjustment, marked by low distress, high motivation, and somewhat satisfactory engagement in health behaviors and (2) affectively distressed, marked by clinically significant distress. At baseline, on average, affectively distressed patients had lower income, higher body mass index, and endorsed higher stress compared with their adaptive adjustment counterparts. At 12-months post intervention, treatment effects were sustained for systolic blood pressure and Framingham risk index

Malaysia mental health country profile.

Malaysia is a tropical country in the heart of south east Asia with a population of 24 million people of diverse ethnic, cultural and religious backgrounds living in harmony in 330,000 km(2) of land on the Asian mainland and Borneo. Malaysia, which lies on the crossroads of trade between east and west Asia, has an ancient history as a centre of trading attracting commerce between Europe, west Asia, India and China. It has had influences from major powers that dominated the region throughout its history. Today the country, after independence in 1957, has embarked on an ambitious development project to make it a developed country by 2020. In this effort the economy has changed from one producing raw material to one manufacturing consumer goods and services and the colonial health system has been overhauled and social systems strengthened to provide better services for its people. The per capita income, which was under 1,000 US dollars at independence, has now passed 4,000 US dollars and continues to grow, with the economy largely based on strong exports that amount to over 100 billion US dollars. The mental health system that was based on institutional care in four mental hospitals at independence from British colonial rule in 1957 with no Malaysian psychiatrists is today largely based on over 30 general hospital psychiatric units spread throughout the country. With three local postgraduate training programmes in psychiatry and 12 undergraduate departments of psychiatry in the country--all started after independence--there is now a healthy development of mental health services. This is being supplemented by a newly established primary care mental health service that covers community mental health by integrating mental health into primary health care. Mental health care at the level of psychiatrists rests with about 140 psychiatrists most of whom had undertaken a four-year masters course in postgraduate psychiatry in Malaysia since 1973. However, there continues to be

The purpose of this study was to determine whether distinct latent profiles of religiousness/spirituality exist for ALWH, and if so, are latent profile memberships associated with health-related quality of life (HRQoL). Latent profile analysis of religiosity identified four profiles/groups. Compared to the other three groups, higher levels of emotional well-being were found among young perinatally infected adolescents who attended religious services, but who did not pray privately, feel God's presence or identify as religious or spiritual. Social HRQoL was significantly higher among the highest overall religious/spiritual group. Understanding adolescent profiles of religiousness/spirituality on HRQoL could inform faith-based interventions. Trial registration NCT01289444.

Pyrrolizidine alkaloids (PAs) are phytochemicals present in hundreds of plant species from different families widely distributed in many geographical regions around the world. PA-containing plants are probably the most common type of poisonous plants affecting livestock, wildlife, and humans. There have been many large-scale human poisonings caused by the consumption of food contaminated with toxic PAs. PAs require metabolic activation to generate pyrrolic metabolites to exert their toxicity. In this study, we developed a novel method to quantify pyrrole-protein adducts present in the blood. This method involves the use of AgNO3 in acidic ethanol to cleave the thiol linkage of pyrrole-protein (DHP-protein) adducts, and the resulting 7,9-di-C2H5O-DHP is quantified by HPLC-ES-MS/MS multiple reaction monitoring analysis in the presence of a known quantity of isotopically labeled 7,9-di-C2D5O-DHP internal standard. Using this method, we determined that diester-type PAs administered to rats produced higher levels of DHP-protein adducts than other types of PAs. The results suggest that DHP-protein adducts can potentially serve as minimally invasive biomarkers of PA exposure.

The aims of this study were to delineate cytokine profiles of systemic lupus erythematosus (SLE), construct prediction models for diagnosis and disease activity using those profiles, and to examine the associations between TNFB Ncol polymorphism, body mass index (BMI) and vitamin D levels with cytokine levels. Two hundred SLE patients and 196 healthy controls participated in this case-control study. Plasma cytokines levels of tumor necrosis factor (TNF)-α, interferon (IFN)-γ, interleukin (IL)-1β, IL- 4, IL-6, IL-10, IL-12 and IL-17 were measured and cytokines profiles were computed. IL-6, IL-12, IL-17, IFN-γ and IL-10 levels were significantly higher in SLE, while IL-4 was lower in SLE. The Th1/Th2 and Th1+Th17/Th2 profiles were significantly higher in SLE than in healthy controls, whereas there were no significant differences in the proinflammatory cytokine profile (TNFα+IL-6+IL-1β). In total, 90.4% of all subjects were correctly classified using Th1+Th17 profile and IL-10 (positively associated) and IL-4 (negatively associated) as predictor variables (sensitivity=66.7% and specificity=96.9%). In all, 20.9% of the variance in the SLE Disease Activity Index was predicted by the Th1+Th17/Th2 ratio, IL-10 and BMI (all positively) and proinflammatory profile (inversely associated). B1/B1 genotype is accompanied by increased IL-17 and Th17/Th2 ratio, while B1/B2 genotype is accompanied by higher IL-4 and IFNγ values. 25-OH vitamin D was inversely associated with IFN-γ levels. SLE is accompanied by Th1, Th17 and Treg profile and lowered IL-4 production. Lowered vitamin D levels and B1/B1 genotype, but not BMI, contribute to changes in cytokines profiles. Future treatments should target Th1, Th2 and Th17 profiles rather than inflammatory cytokines.

Full Text Available Abstract Background: Unhealthy lifestyles occur more often in low-socioeconomic status (SES groups. The assessment of isolated factors reduces the understanding of the problem instead of clarifying the dynamic interaction of these factors in influencing the health. Objective: To study the relationship between nutrition habits and health, and the coexistence of dietary risk factors, according to the occupational status of public municipal employees. Materials and Methods: An electronic epidemiological survey was conducted from September to December 2009. In total, 5,646 public municipal employees (temporary and permanent of the municipality (14.7% answered the questionnaire. Sociodemographic information, health, physical activity, nutritional profile, and working conditions related to eating were investigated. Occupational status was defined by the International Socio-Economic Index. The coexistence of dietary risk factors (low consumption of fruits and vegetables, high consumption of chicken skin and meat fat, and insufficient time to eat at work were evaluated using Venn diagrams. Results: Arterial hypertension, diabetes mellitus and overweight were more frequently reported in the low occupational status, and positive self-reported health was directly related to the occupational status of participants. Conclusion: Differences in health conditions and in the dietary habits of individuals according to occupational status indicate its relevance in the development of public and institutional policies that aim to promote health and reduce inequalities and the need for greater focus on those with lower occupational status.

1986-01-01

Dihydropyridine (DHP)receptor was purified from T-tubules isolated from freeze-thawed rabbit skeletal muscle after French press treatment of microsomal membranes. DHP receptor was labeled with 25 nM [ 3 H]-(+)-PN-200-110 (PN, one of the most potent Ca-antagonists) and solubilized with 1% digitonin. The solubilized receptor was purified in the presence of protease inhibitors (0.1 mM PMSF, 1 mM iodoacetamide, 1μM pepstatin A, 1 mg/l antipain and 0.2 mM o-phenanthroline) using WGA-Sepharose and DEAE-Biogel A column chromatography as well as sucrose density gradient (SDG) centrifugation. The pooled fractions of the SDG had a maximum binding of 590 pmol/mg protein even without correcting for dissociation of PN from the receptors during purification. On SDS-PAGE, a single major band (191 K dalton) was shown both in presence and absence of 20 mM N-ethyl maleimide. However, two major (145 and 103 K dalton) a few minor bands (55,46,32 and 31K dalton) were obtained if the fraction was treated with 20 mM dithiothreitol prior to electrophoresis. The authors data suggest that 191 and 145 k dalton proteins correspond to the α-subunit of the DHP receptor as reported by Curtis and Catterall

The Oral Health Impact Profile (OHIP) has been translated for comparisons across cultural boundaries. This report on a systematic search of literature published between 1994 and 2014 aims to identify an acceptable method of translating psychometric instruments for cross-cultural equivalence, and how they were used to translate the OHIP. An electronic search used the keywords 'cultural adaptation', 'validation', 'Oral Health Impact Profile' and 'OHIP' in MEDLINE and EMBASE databases supplemented by reference links and grey literature. It included papers on methods of cross-cultural translation and translations of the OHIP for dentulous adults and adolescents, and excluded papers without translational details or limited to specific disorders. The search identified eight steps to cross-cultural equivalence, and 36 (plus three supplemental) translations of the OHIP. The steps involve assessment of (i) forward/backward translation by committee, (ii) constructs, (iii) item interpretations, (iv) interval scales, (v) convergent validity, (vi) discriminant validity, (vii) responsiveness to clinical change and (viii) pilot tests. Most (>60%) of the translations involved forward/backward translation by committee, item interpretations, interval scales, convergence, discrimination and pilot tests, but fewer assessed the underlying theory (47%) or responsiveness to clinical change (28%). An acceptable method for translating quality of life-related psychometric instruments for cross-cultural equivalence has eight procedural steps, and most of the 36 OHIP translations involved at least five of the steps. Only translations to Saudi Arabian Arabic, Chinese Mandarin, German and Japanese used all eight steps to claim cultural equivalence with the original OHIP. © 2015 John Wiley & Sons A/S.

Functional interactivity in social media: an examination of Chinese health care organizations' microblog profiles.

Science.gov (United States)

Jiang, Shaohai

2017-09-08

Social media hold enormous potentials as a communication tool for health care due to its interactive nature. However, prior research mainly focused on contingency interactivity of social media, by examining messages sent from health care organizations to audiences, while little is known about functional interactivity, which refers to social media's presence of functions for facilitating communication between users and its interface. That is, how health care organizations use interactive features on social media to communicate with the public. Thus, with a general basis of the functional interactivity framework proposed by Waters et al. (Engaging stakeholders through social networking: how nonprofit organizations are using Facebook. Pub Relat Rev 2009;35:102-106), the current study investigated three aspects of functional interactivity in microblogging, and its subsequent effects. Specifically, this study analyzed 500 Chinese hospitals' profiles on Sina Weibo, the most popular microblogging platform in China. The results showed that the most common functional interactivity feature was organization disclosure, followed by information dissemination, and audience involvement. These interactive features all positively predicted the number of followers. Also, Chinese private hospitals scored significantly higher than public hospitals to use interactive features offered by social media. The findings of this study provide important implications for health care organizations to understand new communicative functions available on social media, incorporate more functions into their profiles and thus provide audiences with greater opportunity to interact with them via social media. © The Author 2017.

Millions of low-income people of diverse ethnicities inhabit stressful old urban industrial neighborhoods. Yet we know little about the health impacts of built-environment stressors and risk perceptions in such settings; we lack even basic health profiles. Difficult access is one reason (it took us 30 months to survey 80 households); the lack of multifaceted survey tools is another. We designed and implemented a pilot vulnerability assessment tool in Worcester, Massachusetts. We answer: (1) How can we assess vulnerability to multiple stressors? (2) What is the nature of complex vulnerability-including risk perceptions and health profiles? (3) How can findings be used by our wider community, and what lessons did we learn? (4) What implications arise for science and policy? We sought a holistic picture of neighborhood life. A reasonably representative sample of 80 respondents captured data for 254 people about: demographics, community concerns and resources, time-activity patterns, health information, risk/stress perceptions, and resources/capacities for coping. Our key findings derive partly from the survey data and partly from our experience in obtaining those data. Data strongly suggest complex vulnerability dominated by psychosocial stress. Unexpected significant gender and ethnic disease disparities emerged: notably, females have twice the disease burden of males, and white females twice the burden of females of color (p Risk Analysis.

The solute specificity profiles (transport and binding) for the nucleobase cation symporter 1 (NCS1) proteins, from the closely related C4 grasses Zea mays and Setaria viridis, differ from that of Arabidopsis thaliana and Chlamydomonas reinhardtii NCS1. Solute specificity profiles for NCS1 from Z. mays (ZmNCS1) and S. viridis (SvNCS1) were determined through heterologous complementation studies in NCS1-deficient Saccharomyces cerevisiae strains. The four Viridiplantae NCS1 proteins transport the purines adenine and guanine, but unlike the dicot and algal NCS1, grass NCS1 proteins fail to transport the pyrimidine uracil. Despite the high level of amino acid sequence similarity, ZmNCS1 and SvNCS1 display distinct solute transport and recognition profiles. SvNCS1 transports adenine, guanine, hypoxanthine, cytosine, and allantoin and competitively binds xanthine and uric acid. ZmNCS1 transports adenine, guanine, and cytosine and competitively binds, 5-fluorocytosine, hypoxanthine, xanthine, and uric acid. The differences in grass NCS1 profiles are due to a limited number of amino acid alterations. These amino acid residues do not correspond to amino acids essential for overall solute and cation binding or solute transport, as previously identified in bacterial and fungal NCS1, but rather may represent residues involved in subtle solute discrimination. The data presented here reveal that within Viridiplantae, NCS1 proteins transport a broad range of nucleobase compounds and that the solute specificity profile varies with species.

Previous studies indicated that maturation inducing hormone, 17α, 20β-Dihydroxy-4-pregnen-3-one (DHP), probably through nuclear progestin receptor (Pgr), might be involved in spermatogenesis and oogenesis in fish. To further elucidate DHP actions in teleostean ovarian differentiation, we analyzed the expression of pgr in the ovary of Nile tilapia (Oreochromis niloticus), and performed RU486 (a synthetic Pgr antagonist) treatment in XX fish from 5 days after hatching (dah) to 120dah. Tilapia Pgr was abundantly expressed in the follicular cells surrounding oocytes at 30 and 90dah. Continuous RU486 treatment led to the blockage of oogenesis and masculinization of somatic cells in XX fish. Termination of RU486 treatment and maintenance in normal condition resulted in testicular differentiation, and estrogen compensation in RU486-treated XX fish successfully restored oogenesis. In RU486-treated XX fish, transcript levels of female dominant genes were significantly reduced, while male-biased genes were evidently augmented. Meanwhile, both germ cell mitotic and meiotic markers were substantially reduced. Consistently, estrogen production levels were significantly declined in RU486-treated XX fish. Taken together, our data further proved that DHP, possibly through Pgr, might be essential in the ovarian differentiation and estrogen production in fish. - Highlights: • DHP plays a critical role in early stage oogenesis of XX tilapia. • Blockage of DHP actions by RU486 treatment led to masculinization and/or sex reversal in XX tilapia. • Both DHP and estrogen are indispensable for ovarian differentiation.

Dihydropyrimidinase (DHP) deficiency is an autosomal recessive disease caused by mutations in the DPYS gene. Patients present with highly elevated levels of dihydrouracil and dihydrothymine in their urine, blood and cerebrospinal fluid. The analysis of the effect of mutations in DPYS on pre-mRNA splicing is hampered by the fact that DHP is primarily expressed in liver and kidney cells. The minigene approach can detect mRNA splicing aberrations using cells that do not express the endogenous mRNA. We have used a minigene-based approach to analyze the effects of a presumptive pre-mRNA splicing mutation in two newly identified Chinese pediatric patients with DHP deficiency. Mutation analysis of DPYS showed that both patients were compound heterozygous for a novel intronic mutation c.1443+5G>A in intron 8 and a previously described missense mutation c.1001A>G (p.Q334R) in exon 6. Wild-type and the mutated minigene constructs, containing exons 7, 8 and 9 of DPYS, yielded different splicing products after expression in HEK293 cells. The c.1443+5G>A mutation resulted in altered pre-mRNA splicing of the DPYS minigene construct with full skipping of exon 8. Analysis of the DHP crystal structure showed that the deletion of exon 8 severely affects folding, stability and homooligomerization of the enzyme as well as disruption of the catalytic site. Thus, the analysis suggests that the c.1443+5G>A mutation results in aberrant splicing of the pre-mRNA encoding DHP, underlying the DHP deficiency in two unrelated Chinese patients.

The principle and method of the electron temperature measurement by means of electron cyclotron emission (ECE) have been described. Several results under different conditions on HL-1M tokamak have been given. The hollow profile of electron temperature appears in some stages, such as current rising, pellet injection and impurity concentration in the plasma centre. When the bias voltage is applied, the electron temperature profile become steeper. All of the phenomena are related with the transport in plasma centre

Receptor model for the molecular basis of tissue selectivity of 1,4-dihydropyridine calcium channel drugs

Our analysis of the solid state conformations of nifedipine [dimethyl 1,4-dihydro-2,6-dimethyl-4-(2-nitrophenyl)-3,5-pyridinecarboxylate] and its 1,4-dihydropyridine (1,4-DHP) analogues produced a cartoon description of the important interactions between these drugs and their voltage-dependent calcium channel receptor. In the present study a molecular-level detailed model of the 1,4-DHP receptor binding site has been built from the published amino acid sequence of the 215-1 subunit of the voltage-dependent calcium channel isolated from rabbit skeletal muscle transverse tubule membranes. The voltage-sensing component of the channel described in this work differs from others reported for the homologous sodium channel in that it incorporates a water structure and a staggered, rather than eclipsed, hydrogen bonded S4 helix conformation. The major recognition surfaces of the receptor lie in helical grooves on the S4 or voltagesensing α-helix that is positioned in the center of the bundle of transmembrane helices that define each of the four calcium channel domains. Multiple binding clefts defined by Arg-X-X-Arg-P-X-X-S `reading frames' exist on the S4 strand. The tissue selectivity of nifedipine and its analogues may arise, in part, from conservative changes in the amino acid residues at the P and S positions of the reading frame that define the ester-binding regions of receptors from different tissues. The crystal structures of two tissue-selective nifedipine analogues, nimodipine [isopropyl (2-methoxyethyl) 1,4-dihydro-2,6- dimethyl-4-(3-nitrophenyl)-3,5-pyridinecarboxylate] and nitrendipine [ethyl methyl 1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3,5-pyridinecarboxylate] are reported. Nimodipine was observed to have an unusual ester side chain conformation that enhances the fit to the proposed ester-sensing region of the receptor.

Favorable levels of all readily measurable major cardiovascular disease risk factors (ie, low risk [LR]) are associated with lower risks of cardiovascular disease morbidity and mortality. Data are not available on LR prevalence among Hispanic/Latino adults of diverse ethnic backgrounds. This study aimed to describe the prevalence of a low cardiovascular disease risk profile among Hispanic/Latino adults in the United States and to examine cross-sectional associations of LR with measures of acculturation. The multicenter, prospective, population-based Hispanic Community Health Study/Study of Latinos examined 16 415 men and women aged 18 to 74 years at baseline (2008-2011) with diverse Hispanic/Latino backgrounds. Analyses involved 14 757 adults (mean age 41.3 years; 60.6% women). LR was defined using national guidelines for favorable levels of serum cholesterol, blood pressure, and body mass index and by not having diabetes mellitus and not currently smoking. Age-adjusted LR prevalence was low (8.4% overall; 5.1% for men, 11.2% for women) and varied by background (4.2% in men of Mexican heritage versus 15.0% in women of Cuban heritage). Lower acculturation (assessed using proxy measures) was significantly associated with higher odds of a LR profile among women only: Age-adjusted odds ratios of having LR were 1.64 (95% CI 1.24-2.17) for foreign-born versus US-born women and 1.96 (95% CI 1.49-2.58) for women residing in the United States profile is low. Lower acculturation is associated with higher odds of a LR profile among women but not men. Comprehensive public health strategies are needed to improve the cardiovascular health of US Hispanic/Latino adults. © 2016 The Authors.

The assessment of changes in oral health-related quality of life (OHRQoL) is challenging because individuals' concepts and internal standards of OHRQoL may change over time. The aim of this study was to detect response shifts in OHRQoL assessments made using the Oral Health Impact Profile (OHIP). Oral health-related quality of life was assessed in a consecutive sample of 126 patients seeking prosthodontic care. Patients were asked to rate their OHRQoL before treatment started and 1 month after treatment was finished, using the German 49-item version of the OHIP. When rating their OHRQoL after treatment, patients were also asked to rate their pre-treatment OHRQoL without having access to their baseline data. The response shift was calculated as the difference in OHIP summary scores between the initial assessment and the retrospective baseline assessment. The OHIP mean scores decreased from 31.8 at the initial baseline assessment to 24.4 after treatment. The retrospective baseline assessment resulted in an OHIP mean score of 38.1, corresponding to a response shift of 6.3 OHIP points. The effect size (Cohen's d = 0.21) of the response shift was considered small. The response shift phenomenon and its magnitude have important implications for dental practice, where patients and dentists often assess perceived treatment effects retrospectively. © 2012 Eur J Oral Sci.

Full Text Available Abstract Background Little is known about the health and social profile of adolescents and adults with Asperger syndrome (AS living in the community. We conducted a study to describe the living, employment and psycho-social situation of a community sample of forty two adults and adolescents with AS, and to describe these indivdiuals' experiences of accessing health services and taking medication. Findings Most respondents (including those over eighteen years of age lived at home with their parents. Most had trouble reading and responding to other people's feelings, and coping with unexpected changes. Difficulties with life skills, such as cleaning, washing and hygiene were prevalent. The majority of respondents were socially isolated and a large minority had been sexually or financially exploited. Almost all respondents had been bullied. Mental health problems such as anxiety or depression were common. 30% of respondents said that they regularly became violent and hit other people and 15% had attempted suicide. More positively, the majority of respondents felt that they could access health services if they had a health problem. Conclusions The results of this study suggest a relatively poor social and health profile for many people with Asperger syndrome living in the community, with high levels of social problems and social exclusion, and difficulties managing day to day tasks such as washing and cleaning; these findings support the results of other studies that have examined psycho-social functioning in this group.

Health profiles and quality of life of 518 survivors of thyroid cancer.

Available literature describes the long-term outcome of thyroid cancer survivors with respect to thyroid cancer but not their overall medical and social well-being. Five hundred eighteen thyroid cancer survivors responded to a survey regarding medical and social impacts of their cancer experience. All had surgery, and 417 (80.5%) also had some radiation. Two thirds (64.5%) reported that cancer created health effects varying by gender and passage of time; neurologic, musculoskeletal, and psychologic problems seemed most prominent. They reported more memory loss and psychologic problems than other cancer survivors and more migraine headaches than both other cancer survivors and the general population. Regarding family and work, they integrated well in society overall. However, unsolicited comments by 24.5% of responders disclosed symptoms reminiscent of thyroid hormone imbalance. Thyroid cancer survivors generally report good health long term but describe distinct, lasting medical problems including symptoms of thyroid dysregulation. The extent and manner in which cancer therapy contributes to the health profile of the group merits further inquiry. Copyright 2003 Wiley Periodicals, Inc.

The effects of lignin content on the activity and action pattern of GH11 endoxylanase from Thermobacillus xylanilyticus were investigated using in vitro reconstituted non-covalent glucuronoarabinoxylan-model lignin (GAX-DHP) nanocomposites. Four types of nanocomposites were prepared, each displaying different lignin contents. Variations in the DHP (model lignin) polymerization process were induced by increasing the coniferyl alcohol concentration. Examination of the morphology of the nanocomposites revealed globular particles enrobed in a matrix. The size of these particles increased in line with the lignin concentration. Physicochemical characterization of the in vitro reconstituted GAX-DHPs strongly suggested that increased particle size is directly related to the solubility and reactivity of coniferyl alcohol, as reflected by changes in the amount of β-O-4 linkages. Evaluation of the impact of the GH11 endoxylanase on the GAX-DHP nanocomposites revealed a negative correlation between the proportion and organization patterns of DHP in the nanocomposites and enzyme activity.

The Australian population that relies on mobile phones exclusively has increased from 5% in 2005 to 29% in 2014. Failing to include this mobile-only population leads to a potential bias in estimates from landline-based telephone surveys. This paper considers the impacts on selected health prevalence estimates with and without the mobile-only population. Using data from the Australian Health Survey - which, for the first time, included a question on telephone status - we examined demographic, geographic and health differences between the landline-accessible and mobile-only population. These groups were also compared to the full population, controlling for the sampling design and differential non-response patterns in the observed sample through weighting and benchmarking. The landline-accessible population differs from the mobile-only population for selected health measures resulting in biased prevalence estimates for smoking, alcohol risk and private health insurance coverage in the full population. The differences remain even after adjusting for age and gender. Using landline telephones only for conducting population health surveys will have an impact on prevalence rate estimates of health risk factors due to the differing profiles of the mobile-only population from the landline-accessible population. © 2016 Public Health Association of Australia.

Health-related behavior, profile of health locus of control and acceptance of illness in patients suffering from chronic somatic diseases.

Konrad Janowski

Full Text Available PURPOSE: The purpose of the study was to determine health-related behaviors, profile of health locus of control (HLC, and to assess the relationships between these constructs among patients suffering from chronic somatic diseases. MATERIAL AND METHODS: Three-hundred adult patients suffering from various chronic diseases participated in the study. The patients' mean age was 54.6 years (SD = 17.57. RESULTS: No statistically significant differences were found between the different clinical groups in health-related behavior, acceptance of illness, internal HLC or chance HLC. Patients with neurologic conditions showed slightly lower powerful others HLC than did some other clinical groups. Health-related behavior was significantly positively related to all three categories of HLC, with most prominent associations observed with powerful others HLC. Only one type of health-related behavior--preventive behavior--correlated significantly and negatively with acceptance of illness. Differences in the frequency of health-related behavior were also found due to gender (women showing more healthy nutritional habits than men, age (older subjects showing more frequent health-promoting behavior, education (higher education was associated with less frequent health-promoting behavior and marital status (widowed subjects reporting more frequent health-promoting behavior. CONCLUSIONS: Health-related behavior in patients with chronic diseases seems to be unrelated to a specific diagnosis; however it shows associations with both internal and external HLC. Sociodemographic factors are also crucial factors determining frequency of health-related behavior in such patients.

The relationship between the chemical structure and biological activity (log IC 50 ) of 40 derivatives of 1,4-dihydropyridines (DHPs) was studied using density functional theory (DFT) and multiple linear regression analysis methods. With the aim of improving the quantitative structure-activity relationship (QSAR) model, the reduced density gradient s( r) of the optimized equilibrium geometries was used as a descriptor to include weak non-covalent interactions. The QSAR model highlights the correlation between the log IC 50 with highest molecular orbital energy (E HOMO ), molecular volume (V), partition coefficient (log P), non-covalent interactions NCI(H4-G) and the dual descriptor [Δf(r)]. The model yielded values of R 2 =79.57 and Q 2 =69.67 that were validated with the next four internal analytical validations DK=0.076, DQ=-0.006, R P =0.056, and R N =0.000, and the external validation Q 2 boot =64.26. The QSAR model found can be used to estimate biological activity with high reliability in new compounds based on a DHP series.

Racial/ethnic disparities in self-rated health persist and according to the social determinants of health framework, may be partially explained by residential context. The relationship between neighborhood factors and self-rated health has been examined in isolation but a more holistic approach is needed to understand how these factors may cluster together and how these neighborhood typologies relate to health. To address this gap, we conducted a latent profile analysis using data from the Chicago Community Adult Health Study (CCAHS; N = 2969 respondents in 342 neighborhood clusters) to identify neighborhood profiles, examined differences in neighborhood characteristics among the identified typologies and tested their relationship to self-rated health. Results indicated four distinct classes of neighborhoods that vary significantly on most neighborhood-level social determinants of health and can be defined by racial/ethnic composition and class. Residents in Hispanic, majority black disadvantaged, and majority black non-poor neighborhoods all had significantly poorer self-rated health when compared to majority white neighborhoods. The difference between black non-poor and white neighborhoods in self-rated health was not significant when controlling for individual race/ethnicity. The results indicate that neighborhood factors do cluster by race and class of the neighborhood and that this clustering is related to poorer self-rated health. Copyright © 2017.

Thermotolerance depends mainly on the health and immune status of the animals. The variation in the immune status of the animals may alter the level of tolerance of animals exposed to heat or cold stress. The present study was conducted to investigate the expression profile of two important nucleotide binding and oligomerization domain receptors (NLRs) (NOD1 and NOD2) and their central signalling molecule RIP2 gene during in vitro thermal-stressed bovine peripheral blood mononuclear cells (PBMCs) of native (Sahiwal) and crossbred (Sahiwal X HF) cattle. We also examined the differential expression profile of certain acute inflammatory cytokines in in vitro thermal-stressed PBMC culture among native and its crossbred counterparts. Results revealed that the expression profile of NOD1/2 positively correlates with the thermal stress, signalling molecule and cytokines. Present findings also highlighted that the expression patterns during thermal stress were comparatively superior among indigenous compared to crossbred cattle which may add references regarding the better immune adaptability of Zebu cattle.

Full Text Available The importance of preventive health care practices has increasingly been recognized in the wake of changing disease profile in India. The disease burden has been shifting from communicable to non-communicable diseases as a result of greater focus on achieving competitiveness in a fast globalizing economy. The rapid pace of social and technological changes has led to adverse life style choices resulting in higher incidence of heart diseases, diabetes, obesity, cancer, and deteriorating inter-personal relations and psychological well-being among individuals. Most of these health risks can considerably be reduced through disseminating science-based information on health promotion and disease prevention including exercise, nutrition, smoking and tobacco cessation, immunization, counseling, fostering good habits of health and hygiene, disease screening and preventive medicine. Prior evidences indicate that preventive health interventions can improve health outcomes in a great deal. In a regressive health delivery system of India where major health expenses on curative health is met by out-of-pocket money, preventive health services hold promise to be cost efficient, clinically effective and equity promoting. This article, therefore, examines in depth the issues and prospects of preventive and promotive health care services in realizing optimum health care needs of the people.

The Republic of Pakistan is a South East Asian country with a population of over 140.7 million. Its population is fast growing and the majority (70%) live in rural areas with a feudal or tribal value system. The economy is dependent on agriculture and 35% of the population live below the poverty line. Islam is the main religion and 'mental illnesses' are stigmatized and widely perceived to have supernatural causes. The traditional healers along with psychiatric services are the main mental health service providers. The number of trained mental health professionals is small as compared to the population demands and specialist services are virtually non-existent. Lack of data on prevalence of various mental illnesses and monitory constraints are the major hurdles in the development of mental health services. A number of innovative programmes to develop indigenous models of care like the 'Community Mental Health Programme' and 'Schools Mental Health Programme' have been developed. These programmes have been found effective in reducing stigma and increase awareness of mental illness amongst the adults and children living in rural areas. Efforts by the government and mental health professionals have led to the implementation of a 'National Mental Health Policy' and 'Mental Health Act' in 2001. These aim at integrating mental health services with the existing health services, improving mental health care delivery and safeguarding the rights of mentally ill people. A favourable political will and the help of international institutions like the World Health Organization are required to achieve these aims.

Full Text Available Abstract Background A practical and simple regimen for all malaria species is needed towards malaria elimination in Indonesia. It is worth to compare the efficacy and safety of a single dose of artemisinin-naphthoquine (AN with a three-day regimen of dihydroartemisinin-piperaquine (DHP, the existing programme drug, in adults with uncomplicated symptomatic malaria. Methods This is a phase III, randomized, open label using sealed envelopes, multi-centre, comparative study between a single dose of AN and a three-day dose of DHP in Jayapura and Maumere. The modified WHO inclusion and exclusion criteria for efficacy study were used in this trial. A total of 401 eligible adult malaria subjects were hospitalized for three days and randomly treated with AN four tablets single dose on day 0 or DHP three to four tablets single daily dose for three days, and followed for 42 days for physical examination, thick and thin smears microscopy, and other necessary tests. The efficacy of drug was assessed by polymerase chain reaction (PCR uncorrected and corrected. Results There were 153 Plasmodium falciparum, 158 Plasmodium vivax and 90 P. falciparum/P. vivax malaria. Mean of fever clearance times were similar, 13.0 ± 10.3 hours in AN and 11.3 ± 7.3 hours in DHP groups. The mean of parasite clearance times were longer in AN compared with DHP (28.0 ± 11.7 hours vs 25.5 ± 12.2 hours, p = 0.04. There were only 12 PCR-corrected P. falciparum late treatment failures: seven in AN and five in DHP groups. The PCR uncorrected and corrected on day −42 of adequate clinical and parasitological responses for treatment of any malaria were 93.7% (95% Cl: 90.3–97.2 and 96.3% (95% Cl: 93.6–99.0 in AN, 96.3% (95% Cl: 93.5–99.0 and 97.3% (95% Cl: 95.0–99.6 in DHP groups. Few and mild adverse events were reported. All the abnormal haematology and blood chemistry values had no clinical abnormality. Conclusion AN and DHP are confirmed very effective

1. It has been suggested that neuronal voltage-sensitive calcium channels (VSCC) may be divided into dihydropyridine (DHP)-sensitive (L) and DHP-insensitive (N and T), and that both the L and the N type channels are attenuated by the peptide blocker omega-conotoxin. Here the effects of omega-conotoxin on release of noradrenaline and uptake of calcium in bovine adrenal chromaffin cells were investigated. 2. Release of noradrenaline in response to 25 mM K+, 65 mM K+, 10 nM bradykinin or 10 microM prostaglandin E1 was not affected by omega-conotoxin in the range 10 nM-1 microM. 3. 45Ca2+ uptake stimulated by high K+ and prostaglandin was attenuated by 1 microM nitrendipine and enhanced by 1 microM Bay K 8644; these calcium fluxes were not modified by 20 nM omega-conotoxin. 4. With superfused rat brain striatal slices in the same medium as the above cell studies, release of dopamine in response to 25 mM K+ was attenuated by 20 nM omega-conotoxin. 5. These results show that in these neurone-like cells, release may be effected by calcium influx through DHP-sensitive but omega-conotoxin-insensitive VSCC, a result inconsistent with the suggestion that omega-conotoxin blocks both L-type and N-type neuronal calcium channels.

Full Text Available Background: Increase in life expectancy of Indians will require revamping the health-care infrastructure for the elderly. In India, either there are not too many specialized geriatric mental health services available across the country or those that are available have problems of resources and quality. With this perspective, the Department of Psychiatry, Government Medical College and Hospital, Chandigarh, developed the Geriatric Mental Health Clinic (GMHC for the elderly residing in and around Chandigarh. The aim of the study was to study the initial 1-year cohort and assess their satisfaction levels as well as to see whether their functioning improves with the intervention so provided. Materials and Methods: Using the “service evaluation framework,” the patients and caregivers who attended the GMHC over a period of 1 year were evaluated using tools such as Hindi Mental State Examination (HMSE, Everyday Abilities Scale for India (EASI, Global Assessment of Function (GAF scale, World Health Organization quality of life-BREF (WHO-QoL-BREF-Hindi version, and Patient Satisfaction Scale (PAT-SAT. In addition, sociodemographic and clinical profile data of the service users were compiled. Results: A total of 105 cases formed the cohort under study, wherein 70% had functional psychiatric illness and almost more than half of the cases had comorbid physical illness, hypertension being the most common. GAF score of 45.42 and WHO-QoL-BREF score of 78.7 at the time of follow-up suggested that there was “slight impairment in socio-occupational functioning” and “poor QoL,” respectively. However, GAF and HMSE scores were significantly decreased in those with organicity. Overall service users reported good service-cum-clinician satisfaction scores on PAT-SAT; there was also significant reduction of EASI score from that of baseline, suggesting improvement in functioning. Conclusions: Findings show that the newly started GMHC, even though in its

The structural similarity among lipid species and the low sensitivity and spectral resolution of nuclear magnetic resonance (NMR) have traditionally hampered the routine use of 1 H NMR lipid profiling of complex biological samples in metabolomics, which remains mostly manual and lacks freely available bioinformatics tools. However, 1 H NMR lipid profiling provides fast quantitative screening of major lipid classes (fatty acids, glycerolipids, phospholipids, and sterols) and some individual species and has been used in several clinical and nutritional studies, leading to improved risk prediction models. In this Article, we present LipSpin, a free and open-source bioinformatics tool for quantitative 1 H NMR lipid profiling. LipSpin implements a constrained line shape fitting algorithm based on voigt profiles and spectral templates from spectra of lipid standards, which automates the analysis of severely overlapped spectral regions and lipid signals with complex coupling patterns. LipSpin provides the most detailed quantification of fatty acid families and choline phospholipids in serum lipid samples by 1 H NMR to date. Moreover, analytical and clinical results using LipSpin quantifications conform with other techniques commonly used for lipid analysis.

The purpose of this study is to confirm the impact of polar functional groups on inter and intra-molecular hydrogen bonding in haloperidol (HP) and droperidol (DP) and, hence, their effects on dissolution using a new approach. To confirm our theory, a new molecule: deshydroxy-haloperidol (DHP) was designed and its synthesis was requested from a contract laboratory. The molecule was then studied and compared to DP and HP. Unlike DHP, both the HP and DP molecules have hydrogen donor groups, therefore, DHP was used to confirm the relative effects of the hydrogen donor group on solubility and crystal packing. The solid dispersions of the three structurally related molecules: HP, DP, and DHP were prepared using PVPK30, and characterized using XRPD and IR. A comparative dissolution study was carried out in aqueous medium. The absence of a hydrogen bonding donor group in DHP resulted in an unexpected increase in its aqueous solubility and dissolution rate from solid dispersion, which is attributed to weaker crystal pack. The increased dissolution rate of HP and DP from solid dispersions is attributed to drug-polymer hydrogen bonding that interferes with the drug-drug intermolecular hydrogen bonding and provides thermodynamic stability of the dispersed drug molecules. The drug-drug intermolecular hydrogen bond is the driving force for precipitation and crystal packing.

Androgen can directly modulate the induction of steroidogenic enzymes by FSH (follicle stimulating hormone) in ovary granulosa cells. In studies of its mechanism of action, the authors examined the androgen effect on granulosa cell interaction with lipoproteins, the physiologic source of cholesterol. After granulosa cells were cultured for 48 hours with and without androgen and/or FSH, the cells were incubated for 24 hours with 125 I-lipoproteins [human high density lipoprotein (HDL), rat HDL, or human low density lipoprotein (LDL)]. The media were then analyzed for lipoprotein protein coat degradation products (mainly 125 I-monoiodotyrosine) and progestin [mainly 20 alpha-dihydroprogesterone (20 alpha-DHP)]. In the absence of FSH and androgen, 2 X 10(5) granulosa cells degraded basal levels of all three lipoproteins, but produced no measurable 20 alpha-DHP. The addition of 10(-7) M androstenedione (A), testosterone (T), or 5 alpha-dihydrotestosterone (DHT) had no effect on lipoprotein protein degradation or 20 alpha-DHP production. FSH alone stimulated lipoprotein protein degradation by 50 to 300% while the addition of androgen synergistically augmented the FSH-stimulated 20 alpha-DHP production as well as protein coat degradation of all three lipoproteins. DHT and T were both effective, indicating that androgens themselves, and not estrogen products, were responsible for the effect on lipoprotein protein degradation and 20 alpha-DHP production

Reliable and valid instruments are essential for understanding health-promoting behaviors in adolescents. This study analyzed the psychometric properties of the Portuguese version of the Adolescent Lifestyle Profile (ALP). A linguistic and cultural translation of the ALP was conducted with 236 adolescents from two different settings: a community (n=141) and a clinical setting (n=95). Internal consistency reliability and confirmatory factor analysis were performed. Results showed an adequate fit to data, yielding a 36-item, seven-factor structure (CMIN/DF=1.667, CFI=0.807, GFI=0.822, RMR=0.051, RMSEA=0.053, PNFI=0.575, PCFI=0.731). The ALP presented a high internal consistency (α=0.866), with the subscales presenting moderate reliability values (from 0.492 to 0.747). The highest values were in Interpersonal Relations (3.059±0.523) and Positive Life Perspective (2.985±0.588). Some gender differences were found. Findings showed that adolescents from the clinic reported an overall healthier lifestyle than those from the community setting (2.598±0.379 vs. 2.504±0.346; t=1.976, p=0.049). The ALP Portuguese version is a psychometrically reliable, valid, and useful measurement instrument for assessing health-promoting lifestyles in adolescence. The ALP is cross-culturally validated and can decisively contribute to a better understanding of adolescent health promotion needs. Additional research is needed to evaluate the instrument's predictive validity, as well as its clinical relevance for practice and research. Copyright © 2015 Sociedade Brasileira de Pediatria.

The differences in health between men and women have been object of great interest, but interpretations tend to be naturalized and essentialists. Gender-oriented studies have criticized this literature and offered new analythical alternatives. The present study was intended to describe the profile and trends of scientific production on gender and health in Brazil. Data sources comprised the Research Groups Directory of Conselho Nacional de Desenvolvimento Científico e Tecnológico (National Research Council), CAPES (Coordination for the Improvement of Higher Education Personnel) Thesis Bank, and four journals available in SciELO--Scientific Eletronic Library Online. Fifty-one groups with at least one line of research in the subject were identified, with regional and institutional concentrations. The results confirmed the marked growth of scientific production in this field as 98 master and 42 doctoral dissertations and 665 articles on gender and health were retrieved. Women authored 86.0% and 89.0% of doctoral and master dissertations respectively, and 70.5% of the articles. Most were published in the 2000s when diversification of the studied topics was also seen. The studied subjects can be divided into five subgroups: reproduction and contraception; gender and violence; sexuality and health with emphasis on STD/AIDS; work and health, including domestic and night work; other emergent or less explored topics. There are major political, epistemological and methodological challenges for strengthening these advancements. The gender perspective offers possibilities for enlightment of theoretical dilemmas in public health. Furthermore, it can be added to other intellectual and political efforts towards understanding health and its determinants and fighting against inequalities and for social justice.

The issue of students' academic failure is one of the most important educational, economic, and social issues. Cognizance of the factors related to academic downfall is so efficient in its prevention and control and leads to protecting governmental assets and labor force. In order to achieve this goal, this study intends to determine the predictive factors of the students' academic performance in Isfahan University of Medical Sciences in terms of their personality profile, mental health, and their demographic characteristics. This study was a descriptive-correlation study on 771 students who entered Isfahan University of Medical Sciences between 2005 and 2007. The information was gathered through using the students' educational and clinical files (for measuring personality characteristics and mental health) and SAMA Software (To get the mean scores). Minnesota Multiphasic Personality Inventory short form and General Health Questionnaire were used for collecting clinical data. The data were analyzed using SPSS 15 (stepwise regression coefficient, variance analysis, Student's t-test, and Spearman correlation coefficient). The results showed that the aforementioned students obtained a normal average for their personality profile and mental health indicators. Of all the reviewed variables, education, age, gender, depression, and hypochondria were the predictive factors of the students' educational performance. It could be concluded that some of the personality features, mental health indicators, and personality profile play such a significant role in the students' educational life that the disorder in any of them affects the students' educational performance and academic failure.

The toroidal equilibrium position in the Extrap T1 toroidal Z-pinch is studied by measuring the currents induced in the external octupole field rings. Radial profiles are obtained by an internal magnetic coil array. From the magnetic field, profiles of current density, plasma pressure, safety factor, resistivity and input power density are deduced. A polynomial model is developed to simulate the measured profiles. The classical ion heat conduction losses in Extrap discharges are calculated using this model and compared to the power input. for polynomials matched to magnetic field profiles measured in present experiments, these losses are small. By varying the coefficients of the polynomials, a region is found where the power input can balance the classical heat conduction losses at higher values of Θ and β o . (Author)

Childhood adversities are key etiological factors in the onset and persistence of psychopathology. In Northern Ireland the Troubles also impacted on the population's psychological health. This study used data from the Northern Ireland Study of Health and Stress a collaborative epidemiological study which used the WMH-CIDI to assess mental health disorders in a nationally representative sample (Part 2, n = 1986). The aims of the study were to assess co-occurrences of childhood adversities and investigate the impact of adversity profiles and conflict experience on psychopathology and suicidal behaviour. Latent Class Analysis uncovered 3 discrete childhood adversity profiles, a low, medium, and high risk class. Individuals from higher risk adversity profiles displayed significantly increased odds of having psychological problems, with conflict exposure also impacting on psychopathology. However, the study revealed that the impact of conflict exposure on suicidal behaviour was moderated by latent class membership and that some adversity may actually be protective. The findings highlight the need to consider that, while adversity can have a negative impact on psychopathology, a lack of adversity early in life may hinder some people from developing adequate coping strategies. Further research is required to identify adversity patterns and other interacting factors that are protective. Copyright © 2018 Elsevier B.V. All rights reserved.

Radioimmunological determination of 5a-pregnane-3, 20-dione and progesterone in the serum in the case of abortus imminens in early pregnancy

1986-01-01

The standardised method of radioimmunological hormone determination of the progesterone concentration in the mother's serum between the sixth and eighteenth week of pregnancy allows for a reliable prognosis in the case of abortus imminens (Knapstein, 1980). Permanently low or declining values with living fetuses indicate an unfavourable ending of the pregnancy. In this work it shall be clarified to what extent the two hormones, progesterone and 5a-DHP, can be used as prognostic parameters. The hormones were retrospectively determined in 83 women with normally progressing pregnancies and 57 women with abortus imminens symptomatology. In the women with abortus imminens symptomatology and with an abortion within a week the progesterone as well as the 5a-DHP median values lay statistically significantly below the values of the normal ones. In the corresponding women with premature births, respectively full term births, the values do not differentiate so clearly. In the abortus imminens group 61% of the women showed progesterone values which lay below the 10th percentile of the normal group, 44% aborted within a week, 10% after a several week long latency, 5% carried full term. 46% of the women had 5a-DHP values which lay below the 10th percentile of the normal group, 35% aborted within a week, 7% after a several week long latency, there was one premature birth and one full term birth. 30% of the women had progesterone values which lay within the 80th interpercentile level of the normal group, 5% aborted within a week. 28% of the women had 5a-DHP values within this same level and 14% aborted within a week. In the normal and abortus imminens groups there is an association between serum progesterone and 5a-MHP. Specificity: 95% for progesterone and 5a-DHP. Sensitivity: 58% (progesterone) and 44% (5a-DHP). (TRV) [de

The aims of this study were to develop a Spanish version (OHIP-Sp of the Oral Health Impact Profile and to evaluate its convergent and discriminative validity, and its internal consistency. Methods The original 49-items OHIP was translated to Spanish, revised for understanding and semantics by two independent dentists, and then translated back to English by an independent bilingual dentist. The data originated in a cross sectional study conducted among high school students from the Province of Santiago, Chile. The study group was sampled using a multistage random cluster procedure yielding 9,203 students aged 12–21 years. All selected students were invited to participate and all filled a questionnaire with information on socio-demographic factors; oral health related behaviors; and self-reported oral health status (good, fair or poor. From this group, 9,163 students also accepted to fill a detailed questionnaire on socio-economic indicators and to receive a clinical examination comprising direct recordings of clinical attachment levels (CAL in molars and incisors, tooth loss, and the presence of necrotizing ulcerative gingival lesions. Results The participation rate and the questionnaire completeness were high with OHIP-Sp total scores being computed for 9,133 subjects. Self-perceived oral health status was associated with the total OHIP-Sp score and all its domains (Spearman rank correlation. The OHIP-Sp total score was also directly associated with the 4 dental outcomes investigated (Mann-Whitney test and the largest impact was found for the outcomes, 'tooth loss' with a mean OHIP-Sp score = 13.5 and 'CAL >= 3 mm' with a mean OHIP-Sp score = 13.0. Conclusion The OHIP-Sp revealed suitable convergent and discriminative validity and appropriate internal consistency (Cronbach's α. Further studies on OHIP

The phylogeny and resistance profiles of human immunodeficiency virus type 1 (HIV-1) protease (PR) and reverse transcriptase (RT) sequences were compared among six patients with HIV-1 who had received numerous treatments. RNA and DNA fractions were obtained from concurrent blood and rectal biopsy...... samples. Phylogenetic trees and resistance profiles showed that the rectal mucosa and the peripheral blood mononuclear cells (PBMCs) harbored different HIV-1 strains. The resistance-associated mutations found in each strain corresponded to the treatment history of the patients. The resistance mutations...... acquired during earlier treatment regimens were detected in the sequences obtained from the rectal samples and in the PBMCs in several of the patients. Also, differences in the resistance profiles were observed between anatomical sites and between RNA and DNA fractions. Thus, a single sample probably...

To analyze the correlation between the satisfaction of professionals from the Hearing Health Care network in two micro-regions of Minas Gerais state and the sociodemographic profile, work process, and work performance in the health service. This is a cross-sectional, observational, analytic study with a non-probabilistic sample including 34 professionals from the Hearing Health Care services. Data collection occurred through individual interviews in the municipality of professional practice. Associations between the Professional Satisfaction variable and the explanatory variables Sociodemographic Data, Work Routine, and Developed Actions were conducted. Professionals with graduate studies were more satisfied with the human resources policy and the activities developed, whereas health civil servants showed more satisfaction with the wage policy and the work schedule. The correlation analysis between work process and satisfaction revealed a moderate positive correlation between items such as Health Promotion Actions, Satisfaction with Diagnostic Equipment, and Satisfaction with Maintenance Equipment. The present study revealed a higher level of satisfaction among professionals with graduate studies (human resources policy and activities developed) and civil servants (wage policy and work schedule). The relevance of this study lies on the important role that health professionals play on the Health Care Network. Additionally, the study of satisfaction level can provide a search for improvements, considering that satisfied professionals not only improve service quality, but also show greater creativity, commitment, and performance.

Transformation invariant image recognition has been an active research area due to its widespread applications in a variety of fields such as military operations, robotics, medical practices, geographic scene analysis, and many others. The primary goal for this research is detection of objects in the presence of image transformations such as changes in resolution, rotation, translation, scale and occlusion. We investigate a biologically-inspired neural network (NN) model for such transformation-invariant object recognition. In a classical training-testing setup for NN, the performance is largely dependent on the range of transformation or orientation involved in training. However, an even more serious dilemma is that there may not be enough training data available for successful learning or even no training data at all. To alleviate this problem, a biologically inspired reinforcement learning (RL) approach is proposed. In this paper, the RL approach is explored for object recognition with different types of transformations such as changes in scale, size, resolution and rotation. The RL is implemented in an adaptive critic design (ACD) framework, which approximates the neuro-dynamic programming of an action network and a critic network, respectively. Two ACD algorithms such as Heuristic Dynamic Programming (HDP) and Dual Heuristic dynamic Programming (DHP) are investigated to obtain transformation invariant object recognition. The two learning algorithms are evaluated statistically using simulated transformations in images as well as with a large-scale UMIST face database with pose variations. In the face database authentication case, the 90° out-of-plane rotation of faces from 20 different subjects in the UMIST database is used. Our simulations show promising results for both designs for transformation-invariant object recognition and authentication of faces. Comparing the two algorithms, DHP outperforms HDP in learning capability, as DHP takes fewer steps to

The Child Oral Health Impact Profile (COHIP) is a validated instrument created to measure the oral health-related quality of life of school-aged children. The purpose of this study was to develop and validate a preschool version of the COHIP (COHIP-PS) for children aged 2-5. The COHIP-PS was developed and validated using a multi-stage process consisting of item selection, face validity testing, item impact testing, reliability and validity testing, and factor analysis. A cross-sectional convenience sample of caregivers having children 2-5 years old from four groups completed item clarity and impact forms. Groups were recruited from pediatric health clinics or preschools/daycare centers, speech clinics, dental clinics, or cleft/craniofacial centers. Participants had a variety of oral health-related conditions, including caries, congenital orofacial anomalies, and speech/language deficiencies such as articulation and language disorders. COHIP-PS. The COHIP-PS was found to have acceptable internal validity (a = 0.71) and high test-retest reliability (0.87), though internal validity was below the accepted threshold for the community sample. While discriminant validity results indicated significant differences across study groups, the overall magnitude of differences was modest. Results from confirmatory factor analyses support the use of a four-factor model consisting of 11 items across oral health, functional well-being, social-emotional well-being, and self-image domains. Quality of life is an integral factor in understanding and assessing children's well-being. The COHIP-PS is a validated oral health-related quality of life measure for preschool children with cleft or other oral conditions. Copyright© 2017 Dennis Barber Ltd.

Posttraumatic stress disorder (PTSD) has been consistently reported as being highly comorbid with major depressive disorder (MDD) and as being associated with health related functional impairment (HRF). We used archival data from 283 previously war-zone deployed Canadian veterans. Latent profile analysis (LPA) was used to uncover patterns of PTSD and MDD comorbidity as measured via the PTSD Checklist-Military version (PCL-M) and the Patient Health Questionnaire-9 (PHQ-9). Individual membership of latent classes was used in a series of one-way ANOVAs to ascertain group differences related to HRF as measured via the Short-Form-36 Health Survey (SF-36). LPA resulted in three discrete patterns of PTSD and MDD comorbidity which were characterized by high symptoms of PTSD and MDD, moderate symptoms, and low symptoms. All ANOVAs comparing class membership on the SF-36 subscales were statistically significant demonstrating group differences across levels of HRF. The group with the highest symptoms reported the worst HRF followed by the medium and low symptom groups. These findings are clinically relevant as they demonstrate the need for continual assessment and targeted treatment of co-occurring PTSD and MDD. Copyright © 2015 Elsevier Ireland Ltd.

Maternal exposure to the endocrine disruptor bisphenol A (BPA) has been linked to offspring reproductive abnormalities. However, exactly how BPA affects offspring fertility remains poorly understood. The aim of the present study was to evaluate the effects of gestational BPA exposure on sperm function, fertility, and proteome profile of F1 spermatozoa in adult mice. Pregnant CD-1 mice (F0) were gavaged with BPA at three different doses (50 μg/kg bw/day, 5 mg/kg bw/day, and 50 mg/kg bw/day) on embryonic days 7 to 14. We investigated the function, fertility, and related processes of F1 spermatozoa at postnatal day 120. We also evaluated protein profiles of F1 spermatozoa to monitor their functional affiliation to disease. BPA inhibited sperm count, motility parameters, and intracellular ATP levels in a dose-dependent manner. These effects appeared to be caused by reduced numbers of stage VIII seminiferous epithelial cells in testis and decreased protein kinase A (PKA) activity and tyrosine phosphorylation in spermatozoa. We also found that BPA compromised average litter size. Proteins differentially expressed in spermatozoa from BPA treatment groups are known to play a critical role in ATP generation, oxidative stress response, fertility, and in the pathogenesis of several diseases. Our study provides mechanistic support for the hypothesis that gestational exposure to BPA alters sperm function and fertility via down-regulation of tyrosine phosphorylation through a PKA-dependent mechanism. In addition, we anticipate that the BPA-induced changes in the sperm proteome might be partly responsible for the observed effects in spermatozoa.

Full Text Available Physical exercise has shown positive effects on symptomatology and on the reduction of comorbidities in population with autism spectrum disorder (ASD. However, there is still no consensus about the most appropriate exercise intervention model for children with ASD. The physical exercise program for children with autism (PEP-Aut protocol designed allow us to (i examine the multivariate associations between ASD symptoms, metabolic profile, physical activity level, physical fitness, and health-related quality of life of children with ASD; (ii assess the effects of a 40-week exercise program on all these aspects of children with ASD. The impact of the exercise program will be assessed based on the sequence of the two phases. Phase 1 is a 12-week cross-sectional study assessing the symptomatology, metabolic profile, physical fitness and physical activity levels, socioeconomic status profile, and health-related quality of life of participants. This phase is the baseline of the following phase. Phase 2 is a 48-week intervention study with a 40-week intervention with exercise that will take place in a specialized center for children with ASD in the city of Maceió-Alagoas, Brazil. The primary outcomes will be change in the symptomatic profile and the level of physical activity of children. Secondary outcomes will be anthropometric and metabolic profiles, aerobic function, grip strength, socioeconomic status, and health-related quality of life. The study will provide critical information on the efficacy of exercise for children with ASD and help guide design and delivery of future programs.

Objective Fieldwork experience is a significant component of many health professional education programs and affects future practice for graduates. The present study used self-reported student data to produce a profile of undergraduate student placement experiences. Methods Cross-sectional surveys exploring placement location, setting and client types, models of supervision, interventions and financial costs were completed by students following each placement. Data were analysed using descriptive analysis. Results Placements were predominantly conducted outside capital cities (69.8%; n=184), with 25.8% (n=68) in rural settings. Students experienced predominantly public health in-patient settings and community settings, with only 15% experiencing private settings. Conclusions The placement profile of undergraduate occupational therapy students appeared to be consistent with workforce reports on occupational therapy professional practice. What is known about the topic? Fieldwork experienced by health professional students is critical to preparing new graduates for practice. Although the World Federation of Occupational Therapy provides guidance on what is required for occupational therapy fieldwork experience, little is known about what students actually experience during their fieldwork placements. What does this paper add? The present study is the first to document the range of fieldwork experienced by occupational therapy students in one program over 1 year, and provides the basis for comparison with other occupational therapy programs, as well as other disciplines nationally and internationally. What are the implications for practitioners? Occupational therapy students experienced few opportunities in private practice or speciality services, and had mostly one-on-one supervision. To provide a future workforce that is able to address the changing health system, it is vital that students are exposed to a range of fieldwork experiences and supervision styles that

To describe the epidemiological profile of tuberculosis cases reported among health care workers in the Tuberculosis Control Program of the Cassiano Antonio of Moraes University Hospital in Vitoria, Brazil. A retrospective descriptive study of secondary data was conducted between 2002 and 2006. Twenty-five cases of health care workers with tuberculosis were reported: 8 in nursing technicians (32%); 4 in doctors (16%); 3 in nurses (12%); 2 in radiology technicians (8%) and 8 in professionals from other categories (32%). Of those 25 health care workers, 14 (56%) were male and 11 (44%) were female. The incidence of the disease was highest among those from 35 to 39 years of age. The predominant clinical presentation was extrapulmonary (12 cases, 48%), followed by pulmonary (11 cases, 44%) and a combination of the two (2 cases, 8%). Regarding comorbidities, AIDS, alcoholism and smoking, respectively, were present in 33.3% of the study population. Outcomes were as follows: 22 cases of cure (88%); 2 transfers (8%); and 1 death (4%). The proportion of health care workers diagnosed with tuberculosis in the period studied was 2.53%. The results show the need for heath care workers who work in the tuberculosis control program to fill out the field "professional occupation" on the tuberculosis case registry database reporting forms. In addition, this situation draws attention to the need to implement an occupational tuberculosis control program.

Several studies have evaluated the independent prognostic value of impairments in single geriatric-assessment (GA) components in elderly cancer patients. None identified homogeneous subgroups. Our aims were to identify such subgroups based on combinations of GA components and to assess their associations with treatment decisions, admission, and death. We prospectively included 1,021 patients aged ≥70 years who had solid or hematologic malignancies and who underwent a GA in one of two French teaching hospitals. Two geriatricians independently selected candidate GA parameters for latent class analysis, which was then performed on the 821 cases without missing data. Age, gender, tumor site, metastatic status, and inpatient versus outpatient status were used as active covariates and predictors of class membership. Outcomes were cancer treatment decisions, overall 1-year mortality, and 6-month unscheduled admissions. Sensitivity analyses were performed on the overall population of 1,021 patients and on 375 newly enrolled patients. We identified four classes: relatively healthy (LC1, 28%), malnourished (LC2, 36%), cognitive and mood impaired (LC3, 15%), and globally impaired (LC4, 21%). Tumor site, metastatic status, age, and in/outpatient status independently predicted class membership (p LC4 was associated with 1-year mortality and palliative treatment compared to LC2 and LC3 (p ≤ .05). We identified four health profiles that may help physicians select cancer treatments and geriatric interventions. Researchers may find these profiles useful for stratifying patients in clinical trials. © The Author 2016. Published by Oxford University Press on behalf of The Gerontological Society of America.

Metabolic syndrome is a cluster of risk factors for type 2 diabetes mellitus and cardiovascular disease. Associations between metabolic syndrome and several types of cancer have recently been documented. We analyzed the sample cohort data from the Korean National Health Insurance Service from 2002, with a follow-up period extending to 2013. The cohort data included 99 565 individuals who participated in the health examination program and whose data were therefore present in the cohort database. The metabolic risk profile of each participant was assessed based on obesity, high serum glucose and total cholesterol levels, and high blood pressure. The occurrence of cancer was identified using Korean National Health Insurance claims data. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models, adjusting for age group, smoking status, alcohol intake, and regular exercise. A total of 5937 cases of cancer occurred during a mean follow-up period of 10.4 years. In men with a high-risk metabolic profile, the risk of colon cancer was elevated (HR, 1.40; 95% CI, 1.14 to 1.71). In women, a high-risk metabolic profile was associated with a significantly increased risk of gallbladder and biliary tract cancer (HR, 2.05; 95% CI, 1.24 to 3.42). Non-significantly increased risks were observed in men for pharynx, larynx, rectum, and kidney cancer, and in women for colon, liver, breast, and ovarian cancer. The findings of this study support the previously suggested association between metabolic syndrome and the risk of several cancers. A high-risk metabolic profile may be an important risk factor for colon cancer in Korean men and gallbladder and biliary tract cancer in Korean women.

A high intake of n-3 PUFA provides health benefits via changes in the n-6/n-3 ratio in blood. In addition to such dietary PUFAs, variants in the fatty acid desaturase 1 (FADS1) gene are also associated with altered PUFA profiles. We used mathematical modeling to predict levels of PUFA in whole blood, based on multiple hypothesis testing and bootstrapped LASSO selected food items, anthropometric and lifestyle factors, and the rs174546 genotypes in FADS1 from 1607 participants (Food4Me Study). The models were developed using data from the first reported time point (training set) and their predictive power was evaluated using data from the last reported time point (test set). Among other food items, fish, pizza, chicken, and cereals were identified as being associated with the PUFA profiles. Using these food items and the rs174546 genotypes as predictors, models explained 26-43% of the variability in PUFA concentrations in the training set and 22-33% in the test set. Selecting food items using multiple hypothesis testing is a valuable contribution to determine predictors, as our models' predictive power is higher compared to analogue studies. As unique feature, we additionally confirmed our models' power based on a test set. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Full Text Available We provide a population-based overview of health behaviours of children and adolescents with type 1 diabetes in comparison to the general population, and analyse their relevance for glycaemic control and self-rated health status.Data from questionnaires of 11- to 17-year-old children and adolescents with diabetes (n = 629 were compared to a representative sample (n = 6,813.Children and adolescents with type 1 diabetes had a significantly increased odds of infrequent physical activity (adjusted OR 1.56, short overall duration of physical activity per week (OR 1.55, difference -1.3 hours/week, and high daily computer use (OR 2.51. They had a lower odds of active and passive smoking (OR 0.31 and OR 0.29, and high daily television time (OR 0.68. The odds of an at least good and excellent self-rated health status was increased with intense physical activity, and decreased with active smoking and prolonged daily use of computer and television. Active smoking and prolonged daily use of computer were associated with higher HbA1c.Children and adolescents with type 1 diabetes showed a different profile of health behaviour. Their overall health may improve if their education stresses specifically frequent physical activity with longer overall duration and less frequent television or computer use.

Ozone profile retrieval from nadir-viewing satellite instruments operating in the ultraviolet-visible range requires accurate calibration of Level-1 (L1) radiance data. Here we study the effects of calibration on the derived Level-2 (L2) ozone profiles for three versions of SCanning Imaging Absorption spectroMeter for Atmospheric ChartograpHY (SCIAMACHY) L1 data: version 7 (v7), version 7 with m-factors (v7mfac) and version 8 (v8). We retrieve nadir ozone profiles from the SCIAMACHY instrument that flew on board Envisat using the Ozone ProfilE Retrieval Algorithm (OPERA) developed at KNMI with a focus on stratospheric ozone. We study and assess the quality of these profiles and compare retrieved L2 products from L1 SCIAMACHY data versions from the years 2003 to 2011 without further radiometric correction. From validation of the profiles against ozone sonde measurements, we find that the v8 performs better than v7 and v7mfac due to correction for the scan-angle dependency of the instrument's optical degradation. Validation for the years 2003 and 2009 with ozone sondes shows deviations of SCIAMACHY ozone profiles of 0.8-15 % in the stratosphere (corresponding to pressure range ˜ 100-10 hPa) and 2.5-100 % in the troposphere (corresponding to pressure range ˜ 1000-100 hPa), depending on the latitude and the L1 version used. Using L1 v8 for the years 2003-2011 leads to deviations of ˜ 1-11 % in stratospheric ozone and ˜ 1-45 % in tropospheric ozone. The SCIAMACHY L1 v8 data can still be improved upon in the 265-330 nm range used for ozone profile retrieval. The slit function can be improved with a spectral shift and squeeze, which leads to a few percent residue reduction compared to reference solar irradiance spectra. Furthermore, studies of the ratio of measured to simulated reflectance spectra show that a bias correction in the reflectance for wavelengths below 300 nm appears to be necessary.

Saw palmetto extract (SPE), used widely for the treatment of benign prostatic hyperplasia (BPH) has been shown to bind alpha(1)-adrenergic, muscarinic and 1,4-dihydropyridine (1,4-DHP) calcium channel antagonist receptors. Major constituents of SPE are lauric acid, oleic acid, myristic acid, palmitic acid and linoleic acid. The aim of this study was to investigate binding affinities of these fatty acids for pharmacologically relevant (alpha(1)-adrenergic, muscarinic and 1,4-DHP) receptors. The fatty acids inhibited specific [(3)H]prazosin binding in rat brain in a concentration-dependent manner with IC(50) values of 23.8 to 136 microg/ml, and specific (+)-[(3)H]PN 200-110 binding with IC(50) values of 24.5 to 79.5 microg/ml. Also, lauric acid, oleic acid, myristic acid and linoleic acid inhibited specific [(3)H]N-methylscopolamine ([(3)H]NMS) binding in rat brain with IC(50) values of 56.4 to 169 microg/ml. Palmitic acid had no effect on specific [(3)H]NMS binding. The affinity of oleic acid, myristic acid and linoleic acid for each receptor was greater than the affinity of SPE. Scatchard analysis revealed that oleic acid and lauric acid caused a significant decrease in the maximal number of binding sites (B(max)) for [(3)H]prazosin, [(3)H]NMS and (+)-[(3)H]PN 200-110. The results suggest that lauric acid and oleic acid bind noncompetitively to alpha(1)-adrenergic, muscarinic and 1,4-DHP calcium channel antagonist receptors. We developed a novel and convenient method of determining 5alpha-reductase activity using LC/MS. With this method, SPE was shown to inhibit 5alpha-reductase activity in rat liver with an IC(50) of 101 microg/ml. Similarly, all the fatty acids except palmitic acid inhibited 5alpha-reductase activity, with IC(50) values of 42.1 to 67.6 microg/ml. In conclusion, lauric acid, oleic acid, myristic acid, and linoleic acid, major constituents of SPE, exerted binding activities of alpha(1)-adrenergic, muscarinic and 1,4-DHP receptors and inhibited 5

Projected impacts of climate change on hydropower potential in China

Hydropower is an important renewable energy source in China, but it is sensitive to climate change, because the changing climate may alter hydrological conditions (e.g., river flow and reservoir storage). Future changes and associated uncertainties in China's gross hydropower potential (GHP) and developed hydropower potential (DHP) are projected using simulations from eight global hydrological models (GHMs), including a large-scale reservoir regulation model, forced by five general circulation models (GCMs) with climate data under two representative concentration pathways (RCP2.6 and RCP8.5). Results show that the estimation of the present GHP of China is comparable to other studies; overall, the annual GHP is projected to change by −1.7 to 2 % in the near future (2020–2050) and increase by 3 to 6 % in the late 21st century (2070–2099). The annual DHP is projected to change by −2.2 to −5.4 % (0.7–1.7 % of the total installed hydropower capacity (IHC)) and −1.3 to −4 % (0.4–1.3 % of total IHC) for 2020–2050 and 2070–2099, respectively. Regional variations emerge: GHP will increase in northern China but decrease in southern China – mostly in south central China and eastern China – where numerous reservoirs and large IHCs currently are located. The area with the highest GHP in southwest China will have more GHP, while DHP will reduce in the regions with high IHC (e.g., Sichuan and Hubei) in the future. The largest decrease in DHP (in %) will occur in autumn or winter, when streamflow is relatively low and water use is competitive. Large ranges in hydropower estimates across GHMs and GCMs highlight the necessity of using multimodel assessments under climate change conditions. This study prompts the consideration of climate change in planning for hydropower development and operations in China, to be further combined with a socioeconomic analysis for strategic expansion.

The urinary excretion profiles of delta 1-tetrahydrocannabinol (delta 1-THC) metabolites have been evaluated in two chronic and two naive marijuana users after smoking and oral administration of [ 14 C]delta 1-THC. Urine was collected for five days after each administration route and analyzed for total delta 1-THC metabolites by radioactivity determination, for delta 1-THC-7-oic acid by high-performance liquid chromatography, and for cross-reacting cannabinoids by the EMIT d.a.u. cannabinoid assay. The average urinary excretion half-life of 14 C-labeled delta 1-THC metabolites was calculated to be 18.2 +/- 4.9 h (+/- SD). The excretion profiles of delta 1-THC-7-oic acid and EMIT readings were similar to the excretion profile of 14 C-labeled metabolites in the naive users. However, in the chronic users the excretion profiles of delta 1-THC-7-oic acid and EMIT readings did not resemble the radioactive excretion due to the heavy influence from previous Cannabis use. Between 8-14% of the radioactive dose was recovered in the urine in both user groups after oral administration. Lower urinary recovery was obtained both in the chronic and naive users after smoking--5 and 2%, respectively

, respectively; p = 0.001). The T1ρ profile of normal hyaline cartilage of the hip is not uniform with the topographic differences identified suggesting regional variations in PG concentration. This study, through determination of lower T1ρ relaxation values, suggests inherently greater PG concentrations in the more anterolateral region of the normal hip hyaline cartilage. Furthermore, it demonstrates that T1ρ MRI has the ability to detect even subtle, microscopic local differences in hyaline cartilage composition. This technique has the potential to facilitate basic science and clinical research by serving as a noninvasive surrogate or biomarker of cartilage health and thus may be added to the growing repertoire of advanced, biochemical MRI techniques for evaluating hyaline cartilage.

Hippocampal CA1 transcriptional profile of sleep deprivation: relation to aging and stress.

Nada M Porter

Full Text Available Many aging changes seem similar to those elicited by sleep-deprivation and psychosocial stress. Further, sleep architecture changes with age suggest an age-related loss of sleep. Here, we hypothesized that sleep deprivation in young subjects would elicit both stress and aging-like transcriptional responses.F344 rats were divided into control and sleep deprivation groups. Body weight, adrenal weight, corticosterone level and hippocampal CA1 transcriptional profiles were measured. A second group of animals was exposed to novel environment stress (NES, and their hippocampal transcriptional profiles measured. A third cohort exposed to control or SD was used to validate transcriptional results with Western blots. Microarray results were statistically contrasted with prior transcriptional studies. Microarray results pointed to sleep pressure signaling and macromolecular synthesis disruptions in the hippocampal CA1 region. Animals exposed to NES recapitulated nearly one third of the SD transcriptional profile. However, the SD-aging relationship was more complex. Compared to aging, SD profiles influenced a significant subset of genes. mRNA associated with neurogenesis and energy pathways showed agreement between aging and SD, while immune, glial, and macromolecular synthesis pathways showed SD profiles that opposed those seen in aging.We conclude that although NES and SD exert similar transcriptional changes, selective presynaptic release machinery and Homer1 expression changes are seen in SD. Among other changes, the marked decrease in Homer1 expression with age may represent an important divergence between young and aged brain response to SD. Based on this, it seems reasonable to conclude that therapeutic strategies designed to promote sleep in young subjects may have off-target effects in the aged. Finally, this work identifies presynaptic vesicular release and intercellular adhesion molecular signatures as novel therapeutic targets to counter

Zhuoyuan Zheng

2014-01-01

Full Text Available Hypertension is a highly prevalent risk factor for cardiovascular disease and it can also lead to other diseases which seriously harm the human health. Screening the risks and finding a clinical model for estimating the risk of onset, maintenance, or the prognosis of hypertension are of great importance to the prevention or treatment of the disease, especially if the indicator can be derived from simple health profile. In this study, we investigate a chronic disease questionnaire data set of 6563 rural citizens in East China and find out a clinical signature that can assess the risk of hypertension easily and accurately. The signature achieves an accuracy of about 83% on the external test dataset, with an AUC of 0.91. Our study demonstrates that a combination of simple lifestyle features can sufficiently reflect the risk of hypertension onset. This finding provides potential guidance for disease prevention and control as well as development of home care and home-care technologies.

Research on the transition to adult care for young adults with type 1 diabetes (T1D) emphasizes transition readiness, with less emphasis on transition outcomes. The relatively few studies that focus on outcomes use a wide variety of measures with little reliance on stakeholder engagement for measure selection. This study engaged multiple stakeholders (i.e., young adults with T1D, parents, pediatric and adult health care providers, and experts) in qualitative interviews to identify the content domain for developing a multidimensional measure of health care transition (HCT) outcomes. The following constructs were identified for a planned measure of HCT outcomes: biomedical markers of T1D control; T1D knowledge/skills; navigation of a new health care system; integration of T1D into emerging adult roles; balance of parental involvement with autonomy; and "ownership" of T1D self-management. The results can guide creation of an initial item pool for a multidimensional profile of HCT outcomes. © The Author 2017.

New approaches are urgently needed to evaluate potential hazards posed by exposure to nanomaterials. Gene expression profiling provides information on potential modes of action and human relevance, and tools have recently become available for pathway-based quantitative risk assessment. The objective of this study was to use toxicogenomics in the context of human health risk assessment. We explore the utility of toxicogenomics in risk assessment, using published gene expression data from C57BL/6 mice exposed to 18, 54 and 162 μg Printex 90 carbon black nanoparticles (CBNP). Analysis of CBNP-perturbed pathways, networks and transcription factors revealed concomitant changes in predicted phenotypes (e.g., pulmonary inflammation and genotoxicity), that correlated with dose and time. Benchmark doses (BMDs) for apical endpoints were comparable to minimum BMDs for relevant pathway-specific expression changes. Comparison to inflammatory lung disease models (i.e., allergic airway inflammation, bacterial infection and tissue injury and fibrosis) and human disease profiles revealed that induced gene expression changes in Printex 90 exposed mice were similar to those typical for pulmonary injury and fibrosis. Very similar fibrotic pathways were perturbed in CBNP-exposed mice and human fibrosis disease models. Our synthesis demonstrates how toxicogenomic profiles may be used in human health risk assessment of nanoparticles and constitutes an important step forward in the ultimate recognition of toxicogenomic endpoints in human health risk. As our knowledge of molecular pathways, dose-response characteristics and relevance to human disease continues to grow, we anticipate that toxicogenomics will become increasingly useful in assessing chemical toxicities and in human health risk assessment.

Full Text Available The 1,4-Dyhidropyridine (DHP is a class of substances that presents a wide spectrum of biological activities. Among these applications, it can be applied on the treatment of cardiovascular diseases e.g. hypertension. This project proposes the synthesis of some DHPs through multicomponent reactions (one pot using bis-(L zinc prolinate (II as catalyst. Initially the synthesis of the precursor enamine was held using the catalyst and later, there was an addition of cinnmaldehyde to the same reaction media. Such procedure resulted on the formation of the compound of interest (Figure 1. Another important factor is that the ultrasound was used to reach the results, which makes such reactions highly convergent and coherent with the principles of the Green Chemistry.

SLE is a common autoimmune disease with considerable morbidity. Ramadan fasting is a religious custom Muslims regularly practice. We aimed to evaluate the effect of Ramadan fasting on SLE patients' disease activity, health quality of life and lipid profile. We conducted this case control study as a pilot study in 40 quiescent SLE patients, 21 cases who decided to fast and 19 controls who decided not to have Ramadan fasting between August and November 2009 in lupus unit of Rheumatology Research Center in Tehran University of Medical Sciences, Iran. They were assessed for SLE Disease Activity Index, lipid profile and quality of life with Short-Form 36 (SF-36) Health Survey, 1 day before Ramadan, the day after and 3 months after Ramadan fasting. After 24.1 ± 5.4 (mean ± SD) days of fasting, anti-ds DNA increased for 0.34 ± 0.41 mmol/dL in cases versus 0.07 ± 0.31 in controls (P = 0.026). Likewise C3 increased more dramatically in cases (16.8 ± 17.5 vs. 2.3 ± 13.2 mg/dL, P = 0.006). Three months after fasting, anti-ds DNA was still increased 0.28 ± 0.46 mmol/dL in cases while a 0.02 ± 0.43 mmol/dL drop in controls was detected (P = 0.04). On the contrary, C3 returned to baseline. These changes were not accompanied with significant changes in disease activity and health quality of life. Ramadan fasting had no effect on lipid profile except for delayed total cholesterol decrease in cases in comparison with controls (16.4 ± 29.4 decrease vs. 4.6 ± 23.9 mg/dL decrease, P = 0.018). Ramadan fasting probably has no detrimental effect on SLE patients' disease activity and their quality of life in the quiescent phase of disease.

Beatty, Kate E; Erwin, Paul Campbell; Brownson, Ross C; Meit, Michael; Fey, James

Health department accreditation is a crucial strategy for strengthening public health infrastructure. The purpose of this study was to investigate local health department (LHD) characteristics that are associated with accreditation-seeking behavior. This study sought to ascertain the effects of rurality on the likelihood of seeking accreditation through the Public Health Accreditation Board (PHAB). Cross-sectional study using secondary data from the 2013 National Association of County & City Health Officials (NACCHO) National Profile of Local Health Departments Study (Profile Study). United States. LHDs (n = 490) that responded to the 2013 NACCHO Profile Survey. LHDs decision to seek PHAB accreditation. Significantly more accreditation-seeking LHDs were located in urban areas (87.0%) than in micropolition (8.9%) or rural areas (4.1%) (P < .001). LHDs residing in urban communities were 16.6 times (95% confidence interval [CI], 5.3-52.3) and micropolitan LHDs were 3.4 times (95% CI, 1.1-11.3) more likely to seek PHAB accreditation than rural LHDs (RLHDs). LHDs that had completed an agency-wide strategic plan were 8.5 times (95% CI, 4.0-17.9), LHDs with a local board of health were 3.3 times (95% CI, 1.5-7.0), and LHDs governed by their state health department were 12.9 times (95% CI, 3.3-50.0) more likely to seek accreditation. The most commonly cited barrier was time and effort required for accreditation application exceeded benefits (73.5%). The strongest predictor for seeking PHAB accreditation was serving an urban jurisdiction. Micropolitan LHDs were more likely to seek accreditation than smaller RLHDs, which are typically understaffed and underfunded. Major barriers identified by the RLHDs included fees being too high and the time and effort needed for accreditation exceeded their perceived benefits. RLHDs will need additional financial and technical support to achieve accreditation. Even with additional funds, clear messaging of the benefits of accreditation

To assess the dietary characteristics of a closed community and their relationship with several health markers and lipid and lipoprotein values in postmenopausal women. Energy and nutrient intake, serum lipids, lipoproteins, antioxidants, peroxides and low-density lipoprotein (LDL) peroxides in addition to several health markers were measured in a closed, postmenopausal female community consuming a diet without meat, meat products and alcoholic beverages. Departamento de Nutrición and Sección Departamental de Química Analítica and Escuela de Especialización de Análisis Clínicos, Universidad Complutense de Madrid, Spain and Lerma, Burgos, Spain. Cereals, vegetables, legumes and fruit, together with milk and eggs, constituted the most important ingredients of the diet consumed. Dietary carbohydrates contributed 42%en and lipids 46.4%en. The SFA/MUFA/PUFA ratio was 1/2/1 and the n-3/n-6 ratio 0.05 (SFA=saturated fatty acids, MUFA=monounsaturated fatty acids, PUFA=polyunsaturated fatty acids). The study community diet was monotonous and made for possible deficiencies of iron, magnesium, zinc, vitamin B(6) and vitamin D, in variable proportions. Routine biochemical and haematological normality markers indicate that only one woman presented hyperglycaemia and hyperuricaemia. Two women had haemoglobin levels 6.21 mmol/l) was 42.8%, while that of high LDL-cholesterol levels (>3.88 mmol/l) was 35.7%, but none of the women displayed levels of high-density lipoprotein (HDL)-cholesterol 1.2 mmol/l or an LDL-cholesterol/HDL-cholesterol ratio>3. Only one woman had apolipoprotein (Apo) B levels >1.5 g/l, while most of the women presented Apo B values <1.2 g/l and an ApoA-1/ApoB ratio &<1.1. Plasma and LDL-peroxide levels, together with the tocopherol and carotene intakes, suggest a good antioxidant status in this population. The diet of the study group seems compatible with a healthy life-profile and permits a more-than-acceptable degree of cardiovascular disease

Tong, Seng Fah; Low, Wah Yun; Ng, Chirk Jenn

2011-01-01

Men's health concerns have evolved from the traditional andrology and male sexual health to a more holistic approach that encompasses male psychological, social and physical health. The poor state of health in men compared to their female counterparts is well documented. A review of the epidemiological data from Malaysia noted a similar trend in which men die at higher rates in under 1 and above 15 years old groups and most disease categories compared to women. In Malaysia, the main causes of death in men are non-communicable diseases and injuries. Risk factors, such as risk-taking behaviour, smoking and hypertension, are prevalent and amenable to early interventions. Erectile dysfunction, premature ejaculation and prostate disorders are also prevalent. However, many of these morbidities go unreported and are not diagnosed early; therefore, opportunities for early intervention are missed. This reflects poor health knowledge and inadequate health-care utilisation among Malaysian men. Their health-seeking behaviour has been shown to be strongly influenced by family members and friends. However, more research is needed to identify men's unmet health-care needs and to develop optimal strategies for addressing them. Because the Malaysian population is aging and there is an increase in sedentary lifestyles, optimizing men's health will remain a challenge unless effective measures are implemented. The existing male-unfriendly health-care system and the negative influence of masculinity on men's health behaviour must be addressed. A national men's health policy based on a male-friendly approach to health-care delivery is urgently needed to provide a framework for addressing these challenges. PMID:21358664

This article seeks to describe the profile of treatment and internment in public psychiatric hospitals in Belo Horizonte, Brazil, from 2002 to 2011. The changes in the characteristics of treatment and the profiles of the patients treated are analyzed in the context of health care reform. It is a study of temporal series with trend analysis by means of linear regression. There was a reduction in the total of patients treated in the period under scrutiny. Inversely, there was an increase in internments with a reduction in length of stay, though no change in readmission rates. Patients from Belo Horizonte prevailed, however a relative increase in demand from the surrounding area was observed. There was a reversal in the prevalence of morbidity switching from psychotic disorders to disorders resulting from the use of alcohol and/or other drugs. The alteration observed in the profile of treatment in public psychiatric hospitals in Belo Horizonte was concomitant with the progressive implementation of community mental health services, which have probably met the demand that was formerly directed to these hospitals. Currently the psychiatric hospital is not the first, much less the only venue for treatment in the mental health network in Minas Gerais.

Full Text Available Background: The Endometriosis Health Profile-30 (EHP-30 is a disease-specific questionnaire to measure the health-related quality of life in patients with endometriosis. The aim of this study was to evaluate the validity and reliability of the Persian version of Endometriosis Health Profile (EHP-30 in women with endometriosis referring to three Gynecology Clinics in Tehran, Iran. Methods: One hundred women (20 to 50 years old with surgically confirmed endometriosis recruited from three outpatient Gynecology Clinics affiliated to the Iran University of Medical Sciences. All 100 patients were asked to complete EHP-30 questionnaire while referring to the Clinics. The findings were analyzed using descriptive statistics, internal reliability consistency, construct validity (using short form-36, which had already been validated in Iran, factor analysis (with principle component analysis method, and item total correlation to assess the validity and reliability of the questionnaire. Results: The internal consistency reliability of the questionnaire was high (Cronbach’s α ranged between 0.80 and 0.93 for core, and 0.78 and 0.90 for modular parts. All items were loaded on their own factors except item 17 (feeling aggressive or violent and item 18 (feeling unwell, which were loaded on pain and social support domains, respectively. Construct validity of EHP-30, established by using SF-36, indicates good correlations in several similar scales of these two questionnaires. Conclusion: The findings of the study demonstrate that Persian version of EHP-30 is a valid and reliable measure to assess the quality of life in women with endometriosis

Near-Optimal Tracking Control of Mobile Robots Via Receding-Horizon Dual Heuristic Programming.

Lian, Chuanqiang; Xu, Xin; Chen, Hong; He, Haibo

2016-11-01

Trajectory tracking control of wheeled mobile robots (WMRs) has been an important research topic in control theory and robotics. Although various tracking control methods with stability have been developed for WMRs, it is still difficult to design optimal or near-optimal tracking controller under uncertainties and disturbances. In this paper, a near-optimal tracking control method is presented for WMRs based on receding-horizon dual heuristic programming (RHDHP). In the proposed method, a backstepping kinematic controller is designed to generate desired velocity profiles and the receding horizon strategy is used to decompose the infinite-horizon optimal control problem into a series of finite-horizon optimal control problems. In each horizon, a closed-loop tracking control policy is successively updated using a class of approximate dynamic programming algorithms called finite-horizon dual heuristic programming (DHP). The convergence property of the proposed method is analyzed and it is shown that the tracking control system based on RHDHP is asymptotically stable by using the Lyapunov approach. Simulation results on three tracking control problems demonstrate that the proposed method has improved control performance when compared with conventional model predictive control (MPC) and DHP. It is also illustrated that the proposed method has lower computational burden than conventional MPC, which is very beneficial for real-time tracking control.

2018-03-01

The evaluation of freestanding integrative cancer clinical programs is challenging and is rarely done. We have developed an approach called the Claim Assessment Profile (CAP) to identify whether evaluation of a practice is justified, feasible, and likely to provide useful information. A CAP was performed in order to (1) clarify the healing claims at InspireHealth, an integrative oncology treatment program, by defining the most important impacts on its clients; (2) gather information about current research capacity at the clinic; and (3) create a program theory and path model for use in prospective research. This case study design incorporates methods from a variety of rapid assessment approaches. Procedures included site visits to observe the program, structured qualitative interviews with 26 providers and staff, surveys to capture descriptive data about the program, and observational data on program implementation. The InspireHealth program is a well-established, multi-site, thriving integrative oncology clinical practice that focuses on patient support, motivation, and health behavior engagement. It delivers patient-centered care via a standardized treatment protocol. There arehigh levels of research interest from staff and resources by which to conduct research. This analysis provides the primary descriptive and claims clarification of an integrative oncology treatment program, an evaluation readiness report, a detailed logic model explicating program theory, and a clinical outcomes path model for conducting prospective research. Prospective evaluation of this program would be feasible and valuable, adding to our knowledge base of integrative cancer therapies.

This study aimed to establish a profile of users of the mental health service for homeless in Cork, comparing this group with those attending a General Adult Service. The homeless group were significantly more likely to be male (89% v. 46%o), unemployed (96% v. 68%), unmarried (98% v. 75%) and under 65 (94% v. 83%). Diagnostically, there was a significantly higher prevalence of schizophrenia (50% v. 34%); personality disorder (37% v. 11%) and substance dependence (74% v. 19%) in the homeless service users. They were more likely to have a history of deliberate self harm (54% v. 21%) and violence (48% v. 10%). Severe mental illness has a high prevalence in the homeless population, with particularly high levels of factors associated with suicide and homicide. Poor compliance and complexity of illness lead to a requirement for significant input from multidisciplinary mental health teams members.

To describe socioeconomic and antiretroviral (ARV) drug resistance profiles among young pregnant women infected with HIV-1. A public health antenatal programme responsible for screening ∼90 000 pregnant women per year for nine different infectious diseases in Central Western Brazil. 96 young pregnant women (15-24 years) infected with HIV-1. Standard interviews and blood samples were taken at the time of recruitment, at the first medical appointment after confirmation of diagnosis of HIV-1 infection, and before ARV prophylaxis initiation. Clinical and laboratory data were retrieved from medical files. HIV-1 pol gene sequences (entire protease/PR, partial reverse transcriptase/RT) were obtained from plasma RNA. ARV resistance mutations (CPR/Stanford HIV-1; International AIDS Society-USA databases) were identified. The median age was 21 years; most reported pregnancies. Possible heterosexual transmission by an HIV-1 infected partner (17%) and commercial sex work (2%) were reported. The median of CD4 cell count was 526 cells/mm(3); the median viral load was: 10 056 copies/mL in ARV-naïve (48/96) patients and 5881 copies/mL in ARV-exposed (48/96) patients. Two probable seroconversion cases during pregnancy were identified in adolescents. One mother-to-child transmission case (1.0%) was observed. Transmitted drug resistance among ARV-naïve patients was 9.3% (CI 95% 3.3% to 19.6%); secondary drug resistance among ARV-exposed patients was 12.5% (CI 95% 4.7% to 25.6%). Despite high access to antenatal care, the low socioeconomic-educational profiles seen in these young HIV-1-infected women highlight the necessity of improved public health educational and preventive strategies regarding HIV infection and early unplanned pregnancy.

A strategy for evaluating the performance of quantitative spectral analysis tools in conditions that better approximate background variation in a metabonomics experiment is presented. Three different urine samples were mixed in known proportions according to a {3, 3} simplex lattice experimental design and analyzed in triplicate by 1D (1)H NMR spectroscopy. Fifty-four urinary metabolites were subsequently quantified from the sample spectra using two methods common in metabolic profiling studies: (1) targeted spectral fitting and (2) targeted spectral integration. Multivariate analysis using partial least-squares (PLS) regression showed the latent structure of the spectral set recapitulated the experimental mixture design. The goodness-of-prediction statistic (Q(2)) of each metabolite variable in a PLS model was calculated as a metric for the reliability of measurement, across the sample compositional space. Several metabolites were observed to have low Q(2) values, largely as a consequence of their spectral resonances having low s/n or strong overlap with other sample components. This strategy has the potential to allow evaluation of spectral features obtained from metabolic profiling platforms in the context of the compositional background found in real biological sample sets, which may be subject to considerable variation. We suggest that it be incorporated into metabolic profiling studies to improve the estimation of matrix effects that confound accurate metabolite measurement. This novel method provides a rational basis for exploiting information from several samples in an efficient manner and avoids the use of multiple spike-in authentic standards, which may be difficult to obtain.

Gut Microbiota Profiling: Metabolomics Based Approach to Unravel Compounds Affecting Human Health.

Vernocchi, Pamela; Del Chierico, Federica; Putignani, Lorenza

2016-01-01

The gut microbiota is composed of a huge number of different bacteria, that produce a large amount of compounds playing a key role in microbe selection and in the construction of a metabolic signaling network. The microbial activities are affected by environmental stimuli leading to the generation of a wide number of compounds, that influence the host metabolome and human health. Indeed, metabolite profiles related to the gut microbiota can offer deep insights on the impact of lifestyle and dietary factors on chronic and acute diseases. Metagenomics, metaproteomics and metabolomics are some of the meta-omics approaches to study the modulation of the gut microbiota. Metabolomic research applied to biofluids allows to: define the metabolic profile; identify and quantify classes and compounds of interest; characterize small molecules produced by intestinal microbes; and define the biochemical pathways of metabolites. Mass spectrometry and nuclear magnetic resonance spectroscopy are the principal technologies applied to metabolomics in terms of coverage, sensitivity and quantification. Moreover, the use of biostatistics and mathematical approaches coupled with metabolomics play a key role in the extraction of biologically meaningful information from wide datasets. Metabolomic studies in gut microbiota-related research have increased, focusing on the generation of novel biomarkers, which could lead to the development of mechanistic hypotheses potentially applicable to the development of nutritional and personalized therapies.

The urinary excretion profiles of delta 1-tetrahydrocannabinol (delta 1-THC) metabolites have been evaluated in two chronic and two naive marijuana users after smoking and oral administration of ({sup 14}C)delta 1-THC. Urine was collected for five days after each administration route and analyzed for total delta 1-THC metabolites by radioactivity determination, for delta 1-THC-7-oic acid by high-performance liquid chromatography, and for cross-reacting cannabinoids by the EMIT d.a.u. cannabinoid assay. The average urinary excretion half-life of {sup 14}C-labeled delta 1-THC metabolites was calculated to be 18.2 +/- 4.9 h (+/- SD). The excretion profiles of delta 1-THC-7-oic acid and EMIT readings were similar to the excretion profile of {sup 14}C-labeled metabolites in the naive users. However, in the chronic users the excretion profiles of delta 1-THC-7-oic acid and EMIT readings did not resemble the radioactive excretion due to the heavy influence from previous Cannabis use. Between 8-14% of the radioactive dose was recovered in the urine in both user groups after oral administration. Lower urinary recovery was obtained both in the chronic and naive users after smoking--5 and 2%, respectively.

2002-09-01

Full Text Available Abstract: Plants that contain pyrrolizidine alkaloids are widely distributed in the world. Although pyrrolizidine alkaloids have been shown to be genotoxic and tumorigenic in experimental animals, the mechanisms of actions have not been fully understood. The results of our recent mechanistic studies suggest that pyrrolizidine alkaloids induce tumors via a genotoxic mechanism mediated by 6,7-dihydro-7-hydroxy-1-hydroxymethyl-5Hpyrrolizine (DHP-derived DNA adduct formation. This mechanism may be general to most carcinogenic pyrrolizidine alkaloids, including the retronecine-, heliotridine-, and otonecinetype pyrrolizidine alkaloids. It is hypothesized that these DHP-derived DNA adducts are potential biomarkers of pyrrolizidine alkaloid tumorigenicity. The mechanisms that involve the formation of DNA cross-linking and endogenous DNA adducts are also discussed.

The use of sets of indicators to assess progress has become commonplace in the global health arena. Exploratory research has suggested that indicators used for global monitoring purposes can play a role in national policy-making, however, the mechanisms through which this occurs are poorly understood. This article reports findings from two qualitative studies that aimed to explore national policy-makers' interpretation and use of indicators from country profiles and reports developed by Countdown to 2015. An initial study aimed at exploring comprehension of Countdown data was conducted at the 2010 joint Women Deliver/Countdown conference. A second study was conducted at the 64th World Health Assembly in 2011, specifically targeting national policy-makers. Semi-structured interviews were carried out with 29 and 22 participants, respectively, at each event. Participants were asked about their understanding of specific graphs and indicators used or proposed for use in Countdown country profiles, and their perception of how such data can inform national policy-making. Responses were categorised using a framework analysis. Respondents in both studies acknowledged the importance of the profiles for tracking progress on key health indicators in and across countries, noting that they could be used to highlight changes in coverage, possible directions for future policy, for lobbying finance ministers to increase resources for health, and to stimulate competition between neighbouring or socioeconomically similar countries. However, some respondents raised questions about discrepancies between global estimates and data produced by national governments, and some struggled to understand the profile graphs shown in the absence of explanatory text. Some respondents reported that use of Countdown data in national policy-making was constrained by limited awareness of the initiative, insufficient detail in the country profiles to inform policy, and the absence of indicators felt to

Despite early dietary treatment phenylketonuria patients have lower IQ and poorer executive functions compared to healthy controls. Cognitive problems in phenylketonuria have often been associated with phenylalanine levels. The present study examined the cognitive profile and mental health in adult phenylketonuria, in relation to phenylalanine levels and tetrahydrobiopterin treatment. Fifty-seven early treated adult patients with phenylketonuria and 57 healthy matched controls (18-40 years) performed IQ subtests and executive function tests from the Amsterdam Neuropsychological Tasks. They also completed the Adult Self-Report on mental health problems. Analyses of variance were performed to examine group differences. Patients with phenylketonuria had normal IQs although lower than controls. They performed poorer on working memory, inhibitory control, and sustained attention tasks. Patients reported Depressive and Avoidant Personality problems more frequently. Specifically, patients with childhood and lifetime phenylalanine ≥360 μmol/L had poorer cognitive and mental health outcomes than controls. In a subset of patients, comparisons between patients on and off tetrahydrobiopterin showed that nontetrahydrobiopterin users (matched for childhood, pretreatment phenylalanine) were slower (on number of tasks) and reported more mental health problems. Adult patients had lower IQ and poorer executive functions than controls, resembling problems observed in younger patients with phenylketonuria, as well as more internalizing problems. Group differences and phenylalanine-outcome associations were smaller than those observed in younger populations. A subset of nontetrahydrobiopterin users, matched for childhood phenylalanine level, had a poorer outcome on some tests than tetrahydrobiopterin users, which might indicate an impact of tetrahydrobiopterin treatment beyond lowering phenylalanine. However, clinical relevance needs further investigation. (PsycINFO Database Record

Full Text Available Introduction: Oral health has an impact on overall general health. It is important to assess the influence of these oral disorders on quality of life. Aim: To validate a Hindi version of the oral health impact profile-14 (OHIP-14 and to assess the instrument's psychometric properties in the Indian population. Materials and Methods: A cross-sectional study was performed in Moradabad city with a sample of 186 participants. The same individuals underwent clinical examinations by a calibrated dentist for recording simplified oral hygiene index (OHI-S index. The OHIP was initially translated and cross-culturally adapted to Hindi following guidelines; then, subsequently validated for the psychometric characteristics of reliability and validity. The reliability of the OHIP-14 was assessed by the use of Cronbach's coefficient. Reproducibility was evaluated by measuring test-retest reliability (intraclass correlation coefficient. Results: The overall value of Cronbach's alpha (α coefficient of the OHIP-14 was estimated to be 0.8. The corrected item-total correlation coefficients values were above 0.2 that has been recommended for including an item in a scale. All Spearman's rank correlation coefficients were statistically significant, whereas the highest association was detected within the physical disability subscale (rs = 0.37, and the lowest within the social disability (rs = 0.08. It was seen that the OHIP-14 scores were higher for those individuals who had higher OHI-S scores and vice-versa. Conclusion: The translated Hindi version of OHIP-14 questionnaire is a reliable and valid instrument to measure the oral health-related quality of life in the Indian adult population.

Population ageing is rapidly becoming a global issue and will have a major impact on health policies and programmes. The World Health Organization's Study on global AGEing and adult health (SAGE) aims to address the gap in reliable data and scientific knowledge on ageing and health in low- and middle-income countries. SAGE is a longitudinal study with nationally representative samples of persons aged 50+ years in China, Ghana, India, Mexico, Russia and South Africa, with a smaller sample of adults aged 18-49 years in each country for comparisons. Instruments are compatible with other large high-income country longitudinal ageing studies. Wave 1 was conducted during 2007-2010 and included a total of 34 124 respondents aged 50+ and 8340 aged 18-49. In four countries, a subsample consisting of 8160 respondents participated in Wave 1 and the 2002/04 World Health Survey (referred to as SAGE Wave 0). Wave 2 data collection will start in 2012/13, following up all Wave 1 respondents. Wave 3 is planned for 2014/15. SAGE is committed to the public release of study instruments, protocols and meta- and micro-data: access is provided upon completion of a Users Agreement available through WHO's SAGE website (www.who.int/healthinfo/systems/sage) and WHO's archive using the National Data Archive application (http://apps.who.int/healthinfo/systems/surveydata).

Horizontal carbon dioxide (CO2) distribution and wind profiles are important information for understanding of the regional sink and source of CO2. The differential absorption lidar (DIAL) and the Doppler lidar with the range resolution is expected to bring several advantages over passive measurements. We have developed a new scanning 1.6μm DIAL and incoherent Doppler lidar system to perform simultaniously measurements of CO2 concentration and wind speed profiles in the atmosphere. The 1.6μm DIAL and Doppler lidar system consists of the Optical Parametric Generator (OPG) transmitter that excited by the LD pumped Nd:YAG laser with high repetition rate (500 Hz). The receiving optics include the near-infrared photomultiplier tube with high quantum efficiency operating at the photon counting mode, a fiber Bragg grating (FBG) filter to detct Doppler shift, and a 25 cm telescope[1][2]. Laser beam is transmitted coaxially and motorized scanning mirror system can scan the laser beam and field of view 0-360deg horizontally and 0-52deg vertically. We report the results of vertical CO2 scanning measurenents and vertical wind profiles. The scanning elevation angles were from 12deg to 24deg with angular step of 4deg and CO2 concentration profiles were obtained up to 1 km altitude with 200 m altitude resolution. We also obtained vertical wind vector profiles by measuring line-of-sight wind profiles at two azimuth angles with a fixed elevation angle 52deg. Vertical wind vector profiles were obtained up to 5 km altitude with 1 km altitude rasolution. This work was financially supported by the System Development Program for Advanced Measurement and Analysis of the Japan Science and Technology Agency. References [1] L. B.

The Brazilian Unified Health Care System (SUS) offers treatment for patients with RA through federal funding (Ministry of Health) and state co-financing. The Clinical Protocol and Therapeutic Guidelines for the treatment of rheumatoid arthritis describe the therapeutic regimen for the disease, including the anticytokines adalimumab, etanercept or infliximab. The aim of this study was to evaluate the profile of registered users of those anticytokines, biologics registered in the Information System of the Pharmaceutical Assistance Specialized Division, managed by the Paraná State Drug Center. A cross-sectional study regarding data from March 2010 was conducted. Based on dispensation data, information regarding the following variables were collected: age; gender; regional health care centers; International Classification of Diseases (ICD); and drug dispensed. In addition, the monthly cost with anticytokines for the SUS was calculated. In the state of Paraná, 923 patients on anticytokines were identified, 40%, 44% and 16% of whom receiving adalimumab, etanercept and infliximab, respectively. This generated a monthly cost of R$3,403,195.59. Regarding the ICD, the distribution of patients was as follows: 55% had ICD M05.8; 27%, ICD M06.0; 9%, ICD M6.8; 8%, ICD M5.0; and 1% had other ICDs related to the disease. The regional health care centers of the state of Paraná with the largest number of patients on anticytokines were in the following municipalities: Ponta Grossa; Cornélio Procópio; Londrina; Cianorte; Maringá; Irati; and Campo Mourão. This study assessed the distribution and profile of users of anticytokines for the rheumatoid arthritis treatment covered by the SUS in the state of Paraná, in March 2010.

Leaf area index (LAI) is an important indicator of ecosystem health. Remote sensing offers the only feasible method of estimating LAI at global and regional scales. Land managers can efficiently monitor changes in vegetation by using NASA data products such as the MODIS LAI 1km product. To increase confidence in use of the MODIS LAI product in Yosemite National Park, we investigated the accuracy of remotely sensed LAI data and created LAI maps using three optical in-situ instruments: the LAI-2000 instrument, digital hemispheric photography (DHP), and the Tracing Radiation and Architecture of Canopies (TRAC) instrument. We compared our in-situ data with three spectral vegetation indices derived from Landsat Thematic Mapper imagery: Reduced Simple Ratio (RSR), Simple Ratio (SR), and Normalized Difference Vegetation Index (NDVI) to produce models which created LAI maps at 30m and 1km resolution. The strongest correlations occurred between DHP LAI values and RSR. Pixel values from the 1km LAI map were then compared to pixel values from a MODIS LAI map. A strong correlation exists between our in-situ data and MODIS LAI values which confirms its accuracy for use by the National Park Service as a decision support tool in Yosemite. The MODIS LAI product is particularly useful because of its high temporal resolution of 1-2 days and can be used to monitor current and future vegetation changes. The model created using the in-situ data can also be applied to Landsat data to provide thirty years of historical LAI values.

Stress is common among college students and associated with adverse health outcomes. This study used the social networking Web site Facebook to identify self-reported stress and associated conditions among college students. Public Facebook profiles of undergraduate freshman at a large Midwestern State University (n = 300) were identified using a Facebook search. Content analysis of Facebook profiles included demographic information and displayed references to stress, weight concerns, depressive symptoms, and alcohol. The mean reported age was 18.4 years, and the majority of profile owners were female (62%). Stress references were displayed on 37% of the profiles, weight concerns on 6%, depressive symptoms on 24%, and alcohol on 73%. The display of stress references was associated with female sex (odds ratio [OR], 2.81; confidence interval [CI], 1.7-4.7), weight concerns (OR, 5.36; CI, 1.87-15.34), and depressive symptoms (OR, 2.7; CI, 1.57-4.63). No associations were found between stress and alcohol references. College freshmen frequently display references to stress on Facebook profiles with prevalence rates similar to self-reported national survey data. Findings suggest a positive association between referencing stress and both weight concerns and depressive symptoms. Facebook may be a useful venue to identify students at risk for stress-related conditions and to disseminate information about campus resources to these students.

Structure, stability and behaviour of nucleic acids in ionic liquids

2014-01-01

Nucleic acids have become a powerful tool in nanotechnology because of their conformational polymorphism. However, lack of a medium in which nucleic acid structures exhibit long-term stability has been a bottleneck. Ionic liquids (ILs) are potential solvents in the nanotechnology field. Hydrated ILs, such as choline dihydrogen phosphate (choline dhp) and deep eutectic solvent (DES) prepared from choline chloride and urea, are ‘green’ solvents that ensure long-term stability of biomolecules. An understanding of the behaviour of nucleic acids in hydrated ILs is necessary for developing DNA materials. We here review current knowledge about the structures and stabilities of nucleic acids in choline dhp and DES. Interestingly, in choline dhp, A–T base pairs are more stable than G–C base pairs, the reverse of the situation in buffered NaCl solution. Moreover, DNA triplex formation is markedly stabilized in hydrated ILs compared with aqueous solution. In choline dhp, the stability of Hoogsteen base pairs is comparable to that of Watson–Crick base pairs. Moreover, the parallel form of the G-quadruplex is stabilized in DES compared with aqueous solution. The behaviours of various DNA molecules in ILs detailed here should be useful for designing oligonucleotides for the development of nanomaterials and nanodevices. PMID:25013178

Confirmations of 2,4-dihydroxypentane (DHP), a model molecule for poly(vinyl alcohol), have been studied by quantum chemistry (QC) calculations and molecular dynamics (MD) simulations. QC calculations at the 6-311G MP2 level show the meso tt conformer to be lowest in energy followed by the racemic tg, due to intramolecular hydrogen bond between the hydroxy groups. The Dreiding force field has been modified to reproduce the QC conformer energies for DHP. MD simulations using this force field have been carried out for DHP molecules in the gas phase, melt, and CHCl3 and water solutions. Extensive intramolecular hydrogen bonding is observed for the gas phase and CHCl3 solution, but not for the melt or aqueous solution, Such a condensed phase effect due to intermolecular interactions results in a drastic change in chain conformations, in agreement with experiments.

The aims of the study were to validate the English and Spanish Versions of the Health-Promoting Lifestyle Profile II (HPLP II) with Hispanic male truck drivers and to determine if there were any differences in drivers' responses based on driving responsibility. The methods included a descriptive correlation design, the HPLP II (English and Spanish versions), and a demographic questionnaire. Fifty-two Hispanic drivers participated in the study. There were no significant differences in long haul and short haul drivers' responses to the HPLP II. Cronbach's alpha for the Spanish version was .97 and the subscales alphas ranged from .74 to .94. The English version alpha was .92 and the subscales ranged from .68 to .84. Findings suggest the subscales of Health Responsibility, Physical Activities, Nutrition, and Spirituality Growth on the HPLP II Spanish and English versions may not adequately assess health-promoting behaviors and cultural influences for the Hispanic male population in the southwestern border region.

To compare the glycemic control and lipid profile of children and adolescents undergoing two different dietetic treatments for type 1 Diabetes Mellitus assisted at the Children and Adolescent's Diabetes Mellitus Health Center-UFRJ. A retrospective longitudinal study conducted between 2002 and 2006. We evaluated the same subjects in two different periods: after 1 year in TD and subsequently after 1 year in CCHO. The evolution of the nutritional status during the dietary treatments was evaluated using Body Mass Index (BMI) for age. The lipid panel was evaluated according to the 1st Guideline for Prevention of Atherosclerosis in Childhood and Adolescence, used in Brazil, and the glycemic control was evaluated by measuring glycated hemoglobin (HbA1c). We evaluated 93 individuals, 38.7% children and 61.3% adolescents. The mean age at study entry was 11.1 (± 2.66) years and the mean disease duration was 6.1 (± 3.2) years. A significant difference in the percentage of adequacy of HbA1c (p = 0.000) and in the values of total plasma cholesterol (p = 0.043) was found after 1 year of CCHO diet, which did not happen during the observation time of TD. The evolution of anthropometric nutritional status showed no significant difference between the beginning and the end of both dietary treatments. The results of this study suggest that a more flexible food orientation program can contribute to the improvement of blood glucose levels without causing deterioration of the lipid profile when compared to TD.

Full Text Available 1-phenoxy-2-propanol is a common and effective anaesthetic for aquatic organisms such as bivalves and pulmonates. However, there are no data regarding its influence on fish organisms. In the present study the anaesthetic efficacy of 1-phenoxy-2-propanol and its influence on biochemical and haematological blood indices of juvenile common carp were studied. For blood profile test, fish were divided into four groups (n = 10. The haematological and blood biochemical profiles of common carp were evaluated 10 min and 24 h after anaesthesia with 1-phenoxy-2-propanol (400 mg·dm-3 and compared to non-anaesthetized control groups. Significant changes (P < 0.05 in red blood cell indices and in white blood cell count were found as well. Increased concentrations of glucose, ammonia and inorganic phosphates indicate that stress reaction occurred. No changes in total protein, globulin, triacylglycerols, alkaline phosphatase, aspartate aminotransferase and calcium were found. Although exposure to 1-phenoxy-2-propanol caused a moderate, temporary stress response in examined fish, we can state that 1-phenoxy-2-propanol can be used as an effective anaesthetic for common carp.

strategy, which makes use of SRP for achieving healthy aging and extending the healthspan, is that of strengthening the homeodynamics through repeated mild stress-induced hormesis by physical, biological and nutritional hormetins. Furthermore, SRP can also be the basis for defining health as a state......Aging is the progressive shrinkage of the homeodynamic space. A crucial component of the homeodynamic space is the stress response (SR), by virtue of which a living system senses disturbance and initiates a series of events for maintenance, repair, adaptation, remodeling and survival. Here we...... discuss the main intracellular SR pathways in human cells, and argue for the need to define and establish the immediate and delayed stress response profiles (SRP) during aging. Such SRP are required to be established at several age-points, which can be the molecular biomarkers of homeodynamic space...

To investigate the effect of retinoblastoma protein-interacting zinc finger gene 1 (RIZ1) upregulation in gene expression profile and oncogenicity of human esophageal squamous cell carcinoma (ESCC) cell line TE13. TE13 cells were transfected with pcDNA3.1(+)/RIZ1 and pcDNA3.1(+). Changes in gene expression profile were screened and the microarray results were confirmed by reverse transcription-polymerase chain reaction (RT-PCR). Nude mice were inoculated with TE13 cells to establish ESCC xenografts. After two weeks, the inoculated mice were randomly divided into three groups. Tumors were injected with normal saline, transfection reagent pcDNA3.1(+) and transfection reagent pcDNA3.1(+)/RIZ1, respectively. Tumor development was quantified, and changes in gene expression of RIZ1 transfected tumors were detected by RT-PCR and Western blotting. DNA microarray data showed that RIZ1 transfection induced widespread changes in gene expression profile of cell line TE13, with 960 genes upregulated and 1163 downregulated. Treatment of tumor xenografts with RIZ1 recombinant plasmid significantly inhibited tumor growth, decreased tumor size, and increased expression of RIZ1 mRNA compared to control groups. The changes in gene expression profile were also observed in vivo after RIZ1 transfection. Most of the differentially expressed genes were associated with cell development, supervision of viral replication, lymphocyte costimulatory and immune system development in esophageal cells. RIZ1 gene may be involved in multiple cancer pathways, such as cytokine receptor interaction and transforming growth factor beta signaling. The development and progression of esophageal cancer are related to the inactivation of RIZ1. Virus infection may also be an important factor.

Gastric cancer is the fourth most common cancer and the second most deadly cancer worldwide. Study on molecular mechanisms of carcinogenesis will play a significant role in diagnosing and treating gastric cancer. Metabolic profiling may offer the opportunity to understand the molecular mechanism of carcinogenesis and help to identify the potential biomarkers for the early diagnosis of gastric cancer. In this study, we reported the metabolic profiling of tissue samples on a large cohort of human gastric cancer subjects (n = 125) and normal controls (n = 54) based on 1 H nuclear magnetic resonance ( 1 H NMR) together with multivariate statistical analyses (PCA, PLS-DA, OPLS-DA and ROC curve). The OPLS-DA model showed adequate discrimination between cancer tissues and normal controls, and meanwhile, the model excellently discriminated the stage-related of tissue samples (stage I, 30; stage II, 46; stage III, 37; stage IV, 12) and normal controls. A total of 48 endogenous distinguishing metabolites (VIP > 1 and p < 0.05) were identified, 13 of which were changed with the progression of gastric cancer. These modified metabolites revealed disturbance of glycolysis, glutaminolysis, TCA, amino acids and choline metabolism, which were correlated with the occurrence and development of human gastric cancer. The receiver operating characteristic diagnostic AUC of OPLS-DA model between cancer tissues and normal controls was 0.945. And the ROC curves among different stages cancer subjects and normal controls were gradually improved, the corresponding AUC values were 0.952, 0.994, 0.998 and 0.999, demonstrating the robust diagnostic power of this metabolic profiling approach. As far as we know, the present study firstly identified the differential metabolites in various stages of gastric cancer tissues. And the AUC values were relatively high. So these results suggest that the metabolic profiling of gastric cancer tissues has great potential in detecting this disease and helping

The health and nutritional conditions of older adults in Mexico are heterogeneous. The prevalence of chronic noncommunicable diseases is elevated with disparities in functionality and socioeconomic inequities. To obtain updated information of the health and nutritional profile of older adults in Mexico in a national representative sample. Information was obtained from 6,687 60 years and older adults from the 2012 National Health and Nutrition Survey (ENSANUT 2012). An index defining the status of «healthy adult» was constructed taking into account the variables of independence in performing activities of daily living (ADL), based on the development by Katz, instrumental ADL, no chronic diseases, nonsmoker and no active use of alcohol. Tables of frequencies and proportions were constructed and expanded to describe the general characteristics and nutritional status of the adult Mexican population. A logistic regression model was used to study changes in the probability of being classified as a healthy adult with respect to different variables of interest. Probabilities using the delta method were estimated to establish 95% confidence intervals. In this study 12.2% of the older adults, were classified as healthy. The logistic regression model adjusted for the variables included in the study shows that the interaction of age and gender is significant (P = 0.068), where the probability of healthy adult status decreases in women with ageing and remains stable for men. Also, living in the southern region of the country significantly decreases the probability of healthy adult status (P = 0.001). Gender of the older adult was not significant. In Mexico, the health conditions of older adults are deficient. Public policies need to be generated that are directed at this population group and will translate into self-care actions in the early stages of life so as to guarantee a healthy future.

The Massachusetts Community Health Information Profile (MassCHIP) has many distinctive features. These features evolved to maximize the usefulness of this query system for a broad group of users with varied needs, differing levels of knowledge about public health, and diverse experience using public health data. Three major features of MassCHIP help target our large user population. These features are as follows: (1) multiple avenues of entry to initiate queries ranging from an alphabetical list of simple topics to detailed International Classification of Disease codes; (2) the inclusion of data sets from other state agencies in addition to those of the Massachusetts Department of Public Health to reflect a broad view of public health; and (3) the capacity to retrieve data for multiple levels of geography, from the neighborhood through the state, including planning districts and hospitals. In this article, we discuss the history and design of MassCHIP, and focus on the features of MassCHIP that target a great variety of user needs and capabilities, and which are distinctive among Web-based data query systems.

1H-13C NMR-based profiling of biotechnological starch utilization

Starch is used in food-and non-food applications as a renewable and degradable source of carbon and energy. Insight into the chemical detail of starch degradation remains challenging as the starch constituents amylose and amylopectin are homopolymers. We show that considerable molecular detail...... of starch fragmentation can be obtained from multivariate analysis of spectral features in optimized 1H-13C NMR spectroscopy of starch fragments to identify relevant features that distinguish processes in starch utilization. As a case study, we compare the profiles of starch fragments in commercial beer...... samples. Spectroscopic profiles of homooligomeric starch fragments can be excellent indicators of process conditions. In addition, differences in the structure and composition of starch fragments have predictive value for down-stream process output such as ethanol production from starch. Thus, high...

An effective HIV vaccine will be essential for the control of the HIV pandemic. This study evaluated the potential global market size and value of a hypothetical HIV vaccine and considered clade diversity, disease burden, partial prevention of acquisition, impact of a reduction in viral load resulting in a decrease in transmission and delay to treatment, health care system differences regarding access, and HIV screening and vaccination, across all public and private markets. Vaccine product profiles varied from a vaccine that would have no effect on preventing infection to a vaccine that would effectively prevent infection and reduce viral load. High disease burden countries (HDBC; HIV prevalence > or = 1%) were assumed to routinely vaccinate pre-sexually active adolescents (10 years old), whereas low disease burden countries (LDBC; HIV prevalence rate market value of $210 million to $2.7 billion, depending on the vaccine product profile. If one-time catch-up campaigns were included (11-14 years old for HDBC and higher risk groups for LDBC), the additional cumulative approximately 70-237 million doses were needed over a 10-year period with a potential market value of approximately $695 million to $13.4 billion, depending on the vaccine product profile. Market size and value varied across market segments with the majority of the value in high income countries and the majority of the demand in low income countries. However, the value of the potential market in low income countries is still significant with up to $550 million annually for routine vaccination only and up to $1.7 billion for a one-time only catch-up campaign in 11-14 years old. In the most detail to date, this study evaluated market size and value of a potential multi-clade HIV vaccine, accounting for differences in disease burden, product profile and health care complexities. These findings provide donors and suppliers highly credible new data to consider in their continued efforts to develop an HIV-1

Proteins incorporated into phospholipid Langmuir-Blodgett (LB) films are a good model system for biomembranes and enzyme immobilization studies. The specific fluidity of biomembranes, an important requisite for enzymatic activity, is naturally controlled by varying phospholipid compositions. In a model system, instead, LB film fluidity may be varied by covering the top layer with different substances able to interact simultaneously with the phospholipid and the protein to be immobilized. In this study, we immobilized a carbohydrate rich Neurospora crassa alkaline phosphatase (NCAP) in monolayers of the sodium salt of dihexadecylphosphoric acid (DHP), a synthetic phospholipid that provides very condensed Langmuir films. The binding of NCAP to DHP Langmuir-Blodgett (LB) films was mediated by the anionic polysaccharide iota-carrageenan (iota-car). Combining results from surface isotherms and the quartz crystal microbalance technique, we concluded that the polysaccharide was essential to promote the interaction between DHP and NCAP and also to increase the fluidity of the film. An estimate of DHP:iota-car ratio within the film also revealed that the polysaccharide binds to DHP LB film in an extended conformation. Furthermore, the investigation of the polysaccharide conformation at molecular level, using sum-frequency vibrational spectroscopy (SFG), indicated a preferential conformation of the carrageenan molecules with the sulfate groups oriented toward the phospholipid monolayer, and both the hydroxyl and ether groups interacting preferentially with the protein. These results demonstrate how interfacial electric fields can reorient and induce conformational changes in macromolecules, which may significantly affect intermolecular interactions at interfaces. This detailed knowledge of the interaction mechanism between the enzyme and the LB film is relevant to design strategies for enzyme immobilization when orientation and fluidity properties of the film provided by the

To investigate the prevalence and severity of oral health-related quality of life in patients treated with removable partial dentures at a publicly-funded dental hospital. The association between patients' demographic profiles, denture-related, variables and oral health-related quality of life was also investigated. A questionnaire was designed to investigate the use and satisfaction of removable partial dentures, and oral health-related quality of life of removable partial denture wearers using the Oral Health Impact Profile-14. The questionnaire was administered to 740 randomly-selected patients who received removable partial dentures during 2005-2008. The response rate was 31.35%. Non-parametric tests and a logistic regression model were used to analyze the association between denture-related variables and oral health-related quality of life. A question on symptoms unrelated to dentures was also analyzed. The Oral Health Impact Profile-14 prevalence calculated was 43.1%. The removable partial denture experience and frequency of use was inversely associated with Oral Health Impact Profile-14 scores. Metal-based removable partial dentures were associated with lower Oral Health Impact Profile prevalence and severity scores. No significant association was found between demographic profile, circumstance for provision of removable partial dentures and Oral Health Impact Profile-14 score. The participants of this study indicated that perceived denture performance, removable partial dentures material, experience, and frequency of use are associated with oral health-related quality of life. © 2012 Blackwell Publishing Asia Pty Ltd.

Doxycycline is an antibiotic agent that inhibits the activity of matrix metalloproteinases (MMPs) present in the extracellular matrix. In this study, the rat incisor was submitted to a hypofunctional condition, and the effects of doxycycline (80 mg/kg/d) on the expression and activity of MMP-2, as well as on eruption rate, were determined in the odontogenic region and in the periodontal ligament for 14 d. Rats were distributed into four groups: normofunctional (NF); doxycyline normofunctional (DNF); hypofunctional (HP); and doxycyline hypofunctional (DHP). The left lower incisors of 10 rats were shortened every 2 d, using a high-rotation drill, to produce the HP and DHP groups, after starting doxycycline treatment (80 mg/kg) by gavage. Eruption was measured using a millimeter ocular, from the gingival margin to the top of the tooth in the HP and DHP groups, and also by a mark made in the tooth previously, in the NF and DNF groups. The hemimandibles were removed and the teeth were extracted to collect the periodontal and odontogenic tissues for immunohistochemical analyses and zymography. The eruption rates were higher in the HP and the DHP groups than in the NF and DNF groups, respectively (p matrix of the periodontal ligament during the tooth-eruption process. © 2016 John Wiley & Sons A/S.

Volker, Arno; Zon, Tim van; Enthoven, Daniel; Verburg, Wesley

2015-01-01

Corrosion is one of the industries major issues regarding the integrity of assets. Currently inspections are conducted at regular intervals to ensure a sufficient integrity level of these assets. Cost reduction while maintaining a high level of reliability and safety of installations is a major challenge. There are many situations where the actual defect location is not accessible, e.g., a pipe support or a partially buried pipe. Guided wave tomography has been developed to reconstruct the wall thickness. In case of bottom of the line corrosion, i.e., a single corrosion pit, a simpler approach may be followed. Data is collected in a pit-catch configuration at the 12 o'clock position using highly dispersive guided waves. The phase spectrum is used to invert for a wall thickness profile in the circumferential direction, assuming a Gaussian defect profile. An EMAT sensor design has been made to measure at the 12 o'clock position of a pipe. The concept is evaluated on measured data, showing good sizing capabilities on a variety simple defect profiles

Reversed field pinch magnetic equilibrium and profile dynamics in Extrap T1-upgrade

Nordlund, P.; Mazur, S.; Drake, J.R.

1992-05-01

An eight station insertable magnetic probe has been installed on the Extrap T1-U machine. The structure of the reversed field pinch magnetic equilibrium and the time evolution of the profiles has been studied. The probe was inserted into sustained high current density RFP plasma, typically 12-16 MA/m 2 on axis. When the probe was inserted there was a somewhat shorter pulse duration and a slightly decaying current. The magnetic field profiles are shift corrected and expressed in a cylindrically symmetric form. All quantities are then derived from cylindrically symmetric equations. In the beginning of the sustainment phase, where the best reproducibility is achieved, we have been able to obtain estimates of the pressure profile consistent with independent measurements of the central pressure. Values of βθ approx = 0.19 and approx = 0.09 are found leading to an estimation of the energy confinement time, with the probe inserted, of τε approx = 5 μs. Profiles of the effective parallel conductivity clearly indicates the presence of a 'dynamo mechanism' sustaining the field configuration. Higher Θ discharges usually exhibit large oscillations in the F-Θ plane. We find that these oscillations represents macroscopic redistribution of the current in the plasma. A cyclic process is found where the parallel current density (μ-profile) tends to peak in the center and then relax towards a flatter and broader configuration. Towards the end of the discharge there is an increasing fluctuation level along with an increasing V loop /I p - Here we find a relative increase in the current density in the edge region resulting in a hollow μ-profile.

Claim Assessment Profile: A Method for Capturing Healthcare Evidence in the Scientific Evaluation and Review of Claims in Health Care (SEaRCH).

Science.gov (United States)

Hilton, Lara; Jonas, Wayne B

2017-02-01

Grounding health claims in an evidence base is essential for determining safety and effectiveness. However, it is not appropriate to evaluate all healthcare claims with the same methods. "Gold standard" randomized controlled trials may skip over important qualitative and observational data about use, benefits, side effects, and preferences, issues especially salient in research on complementary and integrative health (CIH) practices. This gap has prompted a move toward studying treatments in their naturalistic settings. In the 1990s, a program initiated under the National Institutes of Health was designed to provide an outreach to CIH practices for assessing the feasibility of conducting retrospective or prospective evaluations. The Claim Assessment Profile further develops this approach, within the framework of Samueli Institute's Scientific Evaluation and Review of Claims in Health Care (SEaRCH) method. The goals of a Claim Assessment Profile are to clarify the elements that constitute a practice, define key outcomes, and create an explanatory model of these impacts. The main objective is to determine readiness and capacity of a practice to engage in evaluation of effectiveness. This approach is informed by a variety of rapid assessment and stakeholder-driven methods. Site visits, structured qualitative interviews, surveys, and observational data on implementation provide descriptive data about the practice. Logic modeling defines inputs, processes, and outcome variables; Path modeling defines an analytic map to explore. The Claim Assessment Profile is a rapid assessment of the evaluability of a healthcare practice. The method was developed for use on CIH practices but has also been applied in resilience research and may be applied beyond the healthcare sector. Findings are meant to provide sufficient data to improve decision-making for stakeholders. This method provides an important first step for moving existing promising yet untested practices into

2017-07-12

Despite the impact of oral diseases on the quality of life, there is limited updated evidence on oral health status in Limpopo province. To determine the epidemiological profile of patients utilising public oral health services in Limpopo province. This was a descriptive retrospective clinical chart review conducted in five purposively selected district hospitals in Limpopo province. The collected data included the patient's sociodemographic information, reasons for dental consultation, information on the dental or oral diseases and the treatment received. Five hundred clinical files were systematically selected (100 from each district hospital) for the period 01 January 1995 to 31 December 2013. Data were collected using the World Health Organization's indicator age groups, namely 6-year-olds, 12-year-olds, 18-year-olds and 35-44-year-old groups. A data capturing sheet was used to record the collected information. Data were analysed using the statistical software package for social sciences SPSS version 23.0. The majority of patients were in the age group of 6 to 20 years (n = 375, 75%). The majority were male patients (n = 309; 62%). Dental caries was the most common complaint (n = 298, 60%). The second most common main complaint in this age group was retained primary or deciduous teeth (n = 60, 12%) affecting children mainly in the age group of 6 to 12 years. The most common clinical procedure across all five districts was dental extractions (n = 324, 64%). Other clinical interventions included scaling and polishing (n = 33, 12%) and dental restorative care (n = 20, 3%). There is an urgent need to reorient oral health service delivery in Limpopo province to focus more on preventive oral health programmes.

There have been fundamental shifts in the attitude towards, access to and nature of long term care in high income countries. The proportion and profile of the older population living in such settings varies according to social, cultural, and economic characteristics as well as governmental policies. Changes in the profiles of people in different settings are important for policy makers and care providers. Although details will differ, how change occurs across time is important to all, including lower and middle income countries developing policies themselves. Here change is examined across two decades in England. Using the two Cognitive Function and Ageing Studies (CFAS I: 77% response, CFAS II: 56% response), two population based studies of older people carried out in the same areas conducted two decades apart, the study diagnosis of dementia using the Automated Geriatric Examination for Computer Assisted Taxonomy, health and wellbeing were examined, focusing on long term care. The proportion of individuals with three or more health conditions increased for everyone living in long term care between CFAS I (47.6%, 95% CI: 42.3-53.1) and CFAS II (62.7%, 95% CI: 54.8-70.0) and was consistently higher in those without dementia compared to those with dementia in both studies. Functional impairment measured by activities of daily living increased in assisted living facilities from 48% (95% CI: 44%-52%) to 67% (95% CI: 62%-71%). Health profiles of residents in long term care have changed dramatically over time. Dementia prevalence and reporting multiple health conditions have increased. Receiving care in the community puts pressure on unpaid carers and formal services; these results have implications for policies about supporting people at home as well as for service provision within long term care including quality of care, health management, cost, and the development of a skilled, caring, and informed workforce.

Students enter the medical study with different types of motives. Given the importance of academic motivation for good academic achievement of the students, the present study was designed to reveal the possible relationship between academic motivation and achievement in medical students. In this cross-sectional study medical students (N=364) of Nepalese Army institute of Health Sciences were participated and classified to different subgroups using intrinsic and controlled motivation scores. Cluster membership was used as an independent variable to assess differences in study strategies and academic performance. Four clusters were obtained: High Intrinsic High Controlled, Low Intrinsic High Controlled, High Intrinsic Low Controlled, and Low Intrinsic Low Controlled. High Intrinsic High Controlled and High Intrinsic Low Controlled profile students constituted 36.1%, 22.6% of the population, respectively. No significant differences were observed as regards to deep strategy and surface strategy between high interest status motivated and high interest-motivated students. However, both of the clusters had significantly deeper, surface strategy and better academic performance than status-motivated and low-motivation clusters (p motivated and interest-motivated medical students were associated with good deep and surface study strategy and good academic performance. Low-motivation and status-motivated students were associated with the least academic performance with less interest learning behaviors. This reflected that motivation is important required component for good learning outcomes for medical students Keywords: Academic performance; controlled motivation; clusters; intrinsic motivation; motivation.

This study examines the associations between health and stress management (HSM) practices and mental-health disability claims. Data from the Salveo study was collected during 2009-2012 within 60 workplaces nested in 37 companies located in Canada (Quebec) and insured by a large insurance company. In each company, 1 h interviews were conducted with human resources managers in order to obtain data on 63 HSM practices. Companies and workplaces were sorted into the low-claims and high-claims groups according to the median rate of the population of the insurer's corporate clients. Logistic regression adjusted for design effect and multidimensional scaling was used to analyse the data. After controlling for company size and economic sector, task design, demands control, gratifications, physical activity and work-family balance were associated with low mental-health disability claims rates. Further analyses revealed three company profiles that were qualified as laissez-faire, integrated and partially integrated approaches to HSM. Of the three, the integrated profile was associated with low mental-health disability claims rates. The results of this study provide evidence-based guidance for a better control of mental-health disability claims. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract Objective The aim of this study was to compare the prevalence of periodontal pathogens, systemic inflammatory mediators and lipid profiles in type 1 diabetes children (DM) with those observed in children without diabetes (NDM), both with gingivitis. Material and methods Twenty-four DM children and twenty-seven NDM controls were evaluated. The periodontal status, glycemic and lipid profiles were determined for both groups. Subgingival samples of periodontal sites were collected to determine the prevalence of periodontal microorganisms by PCR. Blood samples were collected for IL-1-β, TNF-α and IL-6 analysis using ELISA kits. Results Periodontal conditions of DM and NDM patients were similar, without statistical differences in periodontal indices. When considering patients with gingivitis, all lipid parameters evaluated were highest in the DM group; Capnocytophaga sputigena and Capnocytophaga ochracea were more prevalent in the periodontal sites of DM children. “Red complex” bacteria were detected in few sites of DM and NDM groups. Fusobacterium nucleatum and Campylobacter rectus were frequently found in both groups. Similar levels of IL-1-β, TNF-α and IL-6 were detected in DM and NDM children. Conclusion Clinical and immunological profiles are similar between DM and NDM children. The presence of Capnocytophaga sputigena and Capnocytophaga ochracea were associated with gingivitis in DM children. PMID:28403363

This study aims to develop new antibacterial hydrogel wound dressings composed of poly(aminoethyl) modified chitosan (PAEMCS). FTIR, 1 H NMR, and elemental analysis demonstrated that PAEMCS was successfully synthesized via grafting poly(aminoethyl) groups onto hydroxyl groups on chitin first, and removing acetyl groups from the grafted polymer afterward. XRD and TGA implied its well-defined crystallinity and thermostability. Furthermore, a series of hydrogels were fabricated under the participation of dipotassium hydrogen phosphate (DHP). The gelation tests suggested that the higher concentration of PAEMCS or DHP was beneficial to the formation of hydrogels. The pH values of hydrogels at 37°C were all in the range of 7.12-7.50. The rheological tests indicated that PAEMCS-based hydrogels were of lower DHP addition and higher elasticity than CS-based hydrogels to achieve the same gelation temperature under the same polymer's concentration. Additionally, the swelling, anti-bacteria, and cytotoxicity experiments showed that PAEMCS-based hydrogels possessed excellent hygroscopicity, high antibacterial activity against E. coli, S. aureus, or S. epidermidis, and good cytocompatibility toward L929 cells or HUVECs, respectively. All the results implied that PAEMCS-based hydrogels not only maintained inherent multiple properties of chitosan but also possessed excellent antibacterial activity, and might be promising antibacterial hydrogel dressings used in wound therapy.

Wind tunnel models with a profile depth of t=0.5 m were measured in a laminar wind tunnel by the usual measuring processes. The profile resistance was determined by integration along the width of span. The smooth profiles were examined at Re=0.7/1.0 and 1.5 million. At Re=1.0 million, the position of the changeover points were determined with a stethoscope. Also at this Reynolds number measurements were taken with a trip wire of d=2 mm diameter, directly on the profile nose. The tables contain the co-ordinates of the profiles, the contours, the theoretical speed distributions for 4 different angles of attack, the csub(a)-csub(w) polar measurements and changeover points, and the torque coefficients around the t/4 point.

The physical health of people with serious mental illness is a cause of growing concern to clinicians. Life expectancy in this population may be reduced by up to 25 years and patients often live with considerable physical morbidity that can dramatically reduce quality of life and contribute to social exclusion. This study sought to determine whether the serious mental illness health improvement profile [HIP], facilitated by mental health nurses [MHNs], has the clinical potential to identify physical morbidity and inform future evidence-based care. Retrospective documentation audit and qualitative evaluation of patients' and clinicians' views about the use of the HIP in practice. A nurse-led outpatient medication management clinic, for community adult patients with serious mental illness in Scotland. 31 Community patients with serious mental illness seen in the clinic by 2 MHNs trained to use the HIP. All 31 patients, 9 MHNs, 4 consultant psychiatrists and 12 general practitioners [GPs] (primary care physicians) participated in the qualitative evaluation. A retrospective documentation audit of case notes for all patients where the HIP had been implemented. Semi-structured interviews with patients and their secondary care clinicians. Postal survey of GPs. 189 Physical health issues were identified (mean 6.1 per patient). Items most frequently flagged 'red', suggesting that intervention was required, were body mass index [BMI] (n=24), breast self-examination (n=23), waist circumference (n=21), pulse (n=14) and diet (n=13). Some rates of physical health problems observed were broadly similar to those reported in studies of patients receiving antipsychotics in primary care but much lower than those reported in epidemiological studies. Individualised care was planned and delivered with each patient based on the profile. 28 discreet interventions that included providing advice, promoting health behavioural change, performing an electrocardiogram and making a referral to

Full Text Available Increasing concentrations of in surface water and groundwater can cause ecological and public health effects and has come under increased scrutiny by both environmental scientists and regulatory agencies. For many regions though, including the Sahel of Tunisia, little is known about the sorption capacity of soils. In this project we measured sorption by a profile of an iso-humic soil from Chott Meriem, Tunisia. Soil samples were collected from four soil depths (0–25, 25–60, 60–90, and 90–120 cm on 1 June 2011, and their sorption capacity was determined using batch experiments under laboratory conditions. The effects of contact time, the initial concentration, and the soil-solution ratio on sorption were investigated. In general, the results suggested that was weakly retained by the Chott Meriem soil profile. The quantity of sorption increased with depth, contact time, initial concentration, and soil-solution ratios. To evaluate the sorption capacities of the soil samples at concentrations ranging between 25 and 150 mg L−1 experimental data were fitted to both Freundlich and Langmuir isotherm sorption models. The results indicated that Freundlich model was better for describing sorption in this soil profile.

There is a high prevalence of stress, depression, and burn-out in medical students. Medical students differ widely in personality traits, self-perceptions, and values that may have an impact on their well-being. This study aimed to investigate variability in their personality profiles in relation to their potential for well-being and resilience. Participants were 808 medical students from The University of Queensland. An online questionnaire collected socio-demographics and the Temperament and Character Inventory to assess personality traits. Latent profile analyses identified students' trait profiles. Two distinct personality profiles were identified. Profile 1 ("Resilient") characterized 60% of the sample and was distinguished by low Harm Avoidance combined with very high Persistence, Self-Directedness and Cooperativeness compared to Profile 2 ("Conscientious"). Both Profiles had average levels of Reward Dependence and Novelty Seeking and low levels of Self-Transcendence. Profiles did not differ by age, gender, or country of birth, but rural background students were more likely to have Profile 1. While both Profiles indicate mature and healthy personalities, the combination of traits in Profile 1 is more strongly indicative of well-being and resilience. Finding two distinct profiles of personality highlights the importance of considering combinations of traits and how they may interact with medical students' potential for well-being. Although both profiles of students show healthy personalities, many may lack the resilience to maintain well-being over years of medical training. Programs that develop character and personality self-awareness would enhance their well-being and prepare them to promote the health of their patients.

Full Text Available Objective: The objective of this study was to determine the morbidity profile of patients being treated at the Primary Health Center, their distribution according to gender, and the seasonal trend of diseases. Materials and Methods: The study was done retrospectively using secondary data, over a period of 1 year from June 2007 to July 2008, at the OPD of the Primary Health Center at Patara in Kanpur District, India. The study was aimed to study the pattern of diseases according to the classification provided by the Government of India. The data were collected from the OPD registers of the consultant medical officer, and the diagnosis was classified into communicable diseases, nutritional and metabolic disorders, infectious diseases, obstetric complications, and other diseases including injuries. Results: A total of 6838 patients had been treated at the OPD, which included 2707 males and 4131 females. It was observed that, while communicable diseases constituted about half of the total burden of the diseases with skin infections being the commonest; the non-communicable diseases constituted about one-fifth of the total disease burden. Significant gender differences were evident in the prevalence of certain diseases such as worm infestation, acute respiratory tract infection, urinary tract infection, reproductive tract infection, chronic obstructive pulmonary disease, gastritis, arthritis/gout, falls/injuries/fractures, anemia, pyrexia of unknown origin, and snake bite. Most of the diseases were observed to have a seasonal variation, with the communicable and infectious diseases peaking in the monsoon months. Surprisingly, the non-communicable diseases such as gastritis and falls and injuries also showed a seasonal variation. Conclusion: Many diseases have a seasonal variation and the burden of these diseases could be reduced if we devise measures to detect the changes in their trend through the implementation of surveillance programs in this part

Full Text Available Objective The current study aimed to investigate the impact of high-fat diets composed of different animal and vegetable fat sources on serum metabolic health markers in Japanese quail, as well as the overall lipid content and fatty acid profiles of the edible bird tissues following significantly increased dietary lipid supplementation. Methods Fifty seven male quail were divided into six groups and fed either a standard diet or a diet enriched with one of five different fats (22% coconut oil, lard, palm oil, soybean oil, or sunflower oil for 12 weeks. The birds were subjected to an oral glucose tolerance test following the feeding period, after which they were euthanized and blood, liver, breast, and thigh muscle samples collected. Total fat content and fatty acid profiles of the tissue samples, as well as serum uric acid, triglyceride, cholesterol, total protein, albumin, aspartate transaminase, and total bilirubin concentrations were assessed. Results High-fat diet feeding had no significant effects on the glucose tolerance of the birds. Dietary fatty acid profiles of the added fats were reflected in the lipid profiles of both the liver and breast and thigh muscle tissues, indicating successful transfer of dietary fatty acids to the edible bird tissues. The significantly increased level of lipid inclusion in the diets of the quail used in the present study was unsuccessful in increasing the overall lipid content of the edible bird tissues. Serum metabolic health markers in birds on the high-fat diets were not significantly different from those observed in birds on the standard diet. Conclusion Thus, despite the various high-fat diets modifying the fatty acid profile of the birds’ tissues, unlike in most mammals, the birds maintained a normal health status following consumption of the various high-fat diets.

The objectives of this study were to describe the work done by Brazilian children and adolescents and compare the socioeconomic and health profile of those that worked (or were looking for work) versus non-working youngsters. Based on the 2008 Brazilian National Sample Household Survey (PNAD/2008), we selected children and adolescents 5 to 17 years of age, divided into two analytical categories: "workers" (working or looking for employment) and "non-workers". We calculated prevalence rates for the characteristics of their main work, as well as socioeconomic and health variables comparing the two categories. Poisson regression was used to estimate prevalence ratios, adjusted by health characteristics, with "non-workers" as the reference category. Compared to "non-workers", the "workers" category was associated with a higher proportion of boys; age 14 to 17 years; black or brown skin color; lower school attendance; and worse housing conditions. Child labor was associated with worse self-rated health; chronic backache; arthritis or rheumatism; and depression. Effective policies to support families need to be strengthened to effectively fight child labor.

Uses of nutrient profiling to address public health needs: from regulation to reformulation.

Drewnowski, Adam

Nutrient profiling (NP) models rate the nutritional quality of individual foods, based on their nutrient composition. Their goal is to identify nutrient-rich foods, generally defined as those that contain more nutrients than calories and are low in fat, sugar and salt. NP models have provided the scientific basis for evaluating nutrition and health claims and regulating marketing and advertising to children. The food industry has used NP methods to reformulate product portfolios. To help define what we mean by healthy foods, NP models need to be based on published nutrition standards, mandated serving sizes and open-source nutrient composition databases. Specifically, the development and testing of NP models for public health should follow the seven decision steps outlined by the European Food Safety Authority. Consistent with this scheme, the nutrient-rich food (NRF) family of indices was based on a variable number of qualifying nutrients (from six to fifteen) and on three disqualifying nutrients (saturated fat, added sugar, sodium). The selection of nutrients and daily reference amounts followed nutrient standards for the USA. The base of calculation was 418·4 kJ (100 kcal), in preference to 100 g, or serving sizes. The NRF algorithms, based on unweighted sums of percent daily values, subtracted negative (LIM) from positive (NRn) subscores (NRn - LIM). NRF model performance was tested with respect to energy density and independent measures of a healthy diet. Whereas past uses of NP modelling have been regulatory or educational, voluntary product reformulation by the food industry may have most impact on public health.

The extent to which health and social care (HSC) students hold stereotypical views of other HSC professional groups is of great potential importance to team working in health care. This paper explores students' perceptions of different HSC professional groups at the beginning of their university programmes. Findings are presented from an analysis of baseline data collected as part of the New Generation Project longitudinal cohort study which is assessing the impact of interprofessional education over time on a range of variables including stereotyping. Questionnaires were administered to a cohort of over 1200 students from 10 different HSC professional groups entering their first year of university. Stereotypes were measured using a tool adapted from Barnes et al. (2000) designed to elicit stereotype ratings on a range of nine characteristics. The findings confirm that students arrive at university with an established and consistent set of stereotypes about other health and social care professional groups. Stereotypical profiles were compiled for each professional group indicating the distinctive characteristics of the groups as well as the similarities and differences between groups.Midwives, social workers and nurses were rated most highly on interpersonal skills and on being a team player whilst doctors were rated most highly on academic ability. Doctors, midwives and social workers were perceived as having the strongest leadership role, whilst doctors were also rated most highly on decision making. All professions were rated highly on confidence and professional competence and, with the exception of social workers, on practical skills. A comparison of profiles for each professional group reveals that, for example, pharmacists and doctors were perceived as having very similar characteristics as were social workers, midwives and nurses. However, the profiles of nurses and doctors were perceived to be very different. The implications of these similarities and

The National Health Insurance Service-Health Screening Cohort (NHIS-HEALS) is a cohort of participants who participated in health screening programmes provided by the NHIS in the Republic of Korea. The NHIS constructed the NHIS-HEALS cohort database in 2015. The purpose of this cohort is to offer relevant and useful data for health researchers, especially in the field of non-communicable diseases and health risk factors, and policy-maker. To construct the NHIS-HEALS database, a sample cohort was first selected from the 2002 and 2003 health screening participants, who were aged between 40 and 79 in 2002 and followed up through 2013. This cohort included 514 866 health screening participants who comprised a random selection of 10% of all health screening participants in 2002 and 2003. The age-standardised prevalence of anaemia, diabetes mellitus, hypertension, obesity, hypercholesterolaemia and abnormal urine protein were 9.8%, 8.2%, 35.6%, 2.7%, 14.2% and 2.0%, respectively. The age-standardised mortality rate for the first 2 years (through 2004) was 442.0 per 100 000 person-years, while the rate for 10 years (through 2012) was 865.9 per 100 000 person-years. The most common cause of death was malignant neoplasm in both sexes (364.1 per 100 000 person-years for men, 128.3 per 100 000 person-years for women). This database can be used to study the risk factors of non-communicable diseases and dental health problems, which are important health issues that have not yet been fully investigated. The cohort will be maintained and continuously updated by the NHIS. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

Psychological factors have been suspected to be associated with the development of systemic lupus erythematosus (SLE) and patient's health status. However, psychological profiles among Japanese patients with SLE have been poorly understood. We started a prospective study of female patients with SLE in 1995. Using the baseline data from 279 patients in this prospective study, we cross-sectionally analyzed the relations of clinical factors and social factors to psychological factors, and the association between psychological factors and mental and physical health status. We used the Japanese notion ikigai as an indicator of mental health, and ambulatory activity as an indicator of their physical health, respectively. To measure psychological factors, the short-form of the Eysenck Personality Questionnaire-Revised (short EPQ-R) and the Multidimensional Health Locus of Control (HLOC) scale were used. Active phase of the disease was significantly related to the neuroticism score in the short EPQ-R. Educational level was inversely related to the scores of powerful others and chance HLOC belief. As for health status, the internal HLOC belief was significantly associated with ikigai, and the chance HLOC belief was inversely associated with ambulatory activity. The scores on the short EPQ-R (Extraversion/Introversion and Neuroticism) were exclusively related to ikigai. This study suggests that psychological factors may have effects on both the development of SLE and patient's health status.

To assess the role of protein kinase C (PKC) in the respiratory burst of adherent human polymorphonuclear leukocytes (PMNL), reduction of ferricytochrome C by cells triggered with a phorbol ester (PMA), ionophore A23187, serum-treated zymosan (STZ) or three lipid derivatives, 3-decanoyl-sn-glycerol (G-3-OCOC9), (R,R)-1,4-diethyl-2-O-decyl-L-tartrate (Tt-2-OC10) and 3-decyloxy-5-hydroxymethylphenol (DHP) was examined in a microtiter plate procedure in the presence of inhibitors of PKC and, for comparison, inhibitors of calmodulin, diacylglycerol and myosin light chain kinases and the peptidyl-prolyl cis-trans isomerase activity of fujiphilin. 1) Of the protein kinase inhibitors examined, Ro 31-7549 and staurosporine reduced responses to all stimuli except possibly STZ; in contrast, K252a and the myosin light chain kinase inhibitors ML-7 and ML-9 blocked responses to A23187 and STZ better than those triggered by PMA. H-7 reduced responses to A23187, DHP and G-3-OCOC9, and calphostin, palmitoyl carnitine, sphingosine and the multifunctional drugs TMB-8 and W-7 reduced A23187; they also, when examined, reduced decane derivative-induced O2- production more effectively than PMA- and STZ-triggered responses. Polymyxin B, 4 alpha-PMA and retinal displayed no inhibitory capacity. 2) Of the selective calmodulin antagonists, CGS 9343B, Ro 22-4839 and calmidazolium did not inhibit the oxidative response irrespective of the stimulus used, whereas metofenazate reduced those evoked by A23187, DHP, G-3-OCOC9 and STZ.(ABSTRACT TRUNCATED AT 250 WORDS)

Full Text Available In polypharmacy patients under home health management, pharmacogenetic testing coupled with guidance from a clinical decision support tool (CDST on reducing drug, gene, and cumulative interaction risk may provide valuable insights in prescription drug treatment, reducing re-hospitalization and emergency department (ED visits. We assessed the clinical impact of pharmacogenetic profiling integrating binary and cumulative drug and gene interaction warnings on home health polypharmacy patients.This prospective, open-label, randomized controlled trial was conducted at one hospital-based home health agency between February 2015 and February 2016. Recruitment came from patient referrals to home health at hospital discharge. Eligible patients were aged 50 years and older and taking or initiating treatment with medications with potential or significant drug-gene-based interactions. Subjects (n = 110 were randomized to pharmacogenetic profiling (n = 57. The study pharmacist reviewed drug-drug, drug-gene, and cumulative drug and/or gene interactions using the YouScript® CDST to provide drug therapy recommendations to clinicians. The control group (n = 53 received treatment as usual including pharmacist guided medication management using a standard drug information resource. The primary outcome measure was the number of re-hospitalizations and ED visits at 30 and 60 days after discharge from the hospital. The mean number of re-hospitalizations per patient in the tested vs. untested group was 0.25 vs. 0.38 at 30 days (relative risk (RR, 0.65; 95% confidence interval (CI, 0.32-1.28; P = 0.21 and 0.33 vs. 0.70 at 60 days following enrollment (RR, 0.48; 95% CI, 0.27-0.82; P = 0.007.

Metabolomic analysis of feces can provide useful insight on the metabolic status, the health/disease state of the human/animal and the symbiosis with the gut microbiome. As a result, recently there is increased interest on the application of holistic analysis of feces for biomarker discovery. For metabolomics applications, the sample preparation process used prior to the analysis of fecal samples is of high importance, as it greatly affects the obtained metabolic profile, especially since feces, as matrix are diversifying in their physicochemical characteristics and molecular content. However there is still little information in the literature and lack of a universal approach on sample treatment for fecal metabolic profiling. The scope of the present work was to study the conditions for sample preparation of rat feces with the ultimate goal of the acquisition of comprehensive metabolic profiles either untargeted by NMR spectroscopy and GC-MS or targeted by HILIC-MS/MS. A fecal sample pooled from male and female Wistar rats was extracted under various conditions by modifying the pH value, the nature of the organic solvent and the sample weight to solvent volume ratio. It was found that the 1/2 (w f /v s ) ratio provided the highest number of metabolites under neutral and basic conditions in both untargeted profiling techniques. Concerning LC-MS profiles, neutral acetonitrile and propanol provided higher signals and wide metabolite coverage, though extraction efficiency is metabolite dependent. Copyright © 2016 Elsevier B.V.

Full Text Available Marine biodiversity represents an exceptional source of natural resources. Their use in a sustainable way may ensure alternative food sources for human consumption, which scarcity is anticipated. Macroalgae, also known as seaweed, are an outstanding example of this biodiversity and are considered an excellent source of a wide number of chemical compounds with beneficial health effects [1]. According to their pigmentation, they can be distinguished in green (Chlorophytaea, brown (Phaeophytaea and red (Rhodophytaea, showing differences in nutritional and chemical compositions [1]. Some macroalgae are widely used as food ingredients in oriental countries as a good source of fiber and protein. Alternatively, they are also considered a source of nutraceuticals, providing health benefits such as anti-inflamatory, anti-allergic, antimutagenic, antitumor, antidiabetic, antioxidant, antihyperthensive and neuroprotective properties [2]. Indeed, macroalgae are a very attractive material for the food, pharmaceutical and cosmetic industries. According to some studies red seaweeds seem to be the most suitable source of proteins for human nutrition [3]. The aim of this study was to evaluate the nutritional profile of the most consumed species of red seaweed that are commercially available in the market. Red species as Palmaria palmata (Dulse, Porphyra tenera (Nori and Eisenia bicyclis (Arame, were analyzed. Moisture determination was performed using a Scaltec SMO01 moisture analyzer. The ashes were obtained by incineration at 500ºC. The protein content was determined using the Kjeldahl procedure and total fat was measured through Soxhlet method. The carbohydrates were calculated indirectly by difference. In addition, chlorides were volumetrically determined and vitamin E profile was analysed by HPLC/DAD/FLD. The algae samples are commercialized dry, so the moisture content was very low, around 10%. The ash content was around 10-17%. Protein levels ranged from

Simultaneous contributions of self-esteem, depression, and anxiety to weight and perceived physical health in young adults is understudied. A diverse sample of 424 young adults completed measures of shape/weight based self-esteem, depression, anxiety, and perceived physical health. Height and weight were measured to calculate body mass index (BMI). Latent profile analysis was conducted to derive patterns of depression, anxiety, and shape/weight based self-esteem. Then, we examined the association of the profiles with weight status and perceived physical health. Three profiles emerged: (1) High Shape/Weight Influence (HSWI); (2) Low Shape/Weight, Depression, & Anxiety Influence (LSWDAI); and (3) High Depression & Anxiety Influence (HDAI). The HSWI profile had significantly higher BMI than the LSWDAI and HDAI profiles, and significantly lower perceived physical health than the LSWDAI profile. Over emphasis on shape/weight, regardless of depression and anxiety, is associated with elevated weight and negative internalized health views. Copyright © 2018 Elsevier Ltd. All rights reserved.

The 2009 flu pandemic was a global outbreak of a new strain of H1N1 influenza virus often referred colloquially as "swine flu". The objectives of the study were: (1) To know the sociodemographic and awareness profile of visitors attending swine flu screening booths. (2) To reveal sources of information. The present cross-sectional study was undertaken among the visitors (18 years and above) attending swine flu screening booths organised within the Belgaum city during Ganesh festival from 28-08-2009 to 03-09-2009 by interviewing them using predesigned, pretested structured questionnaire on swine flu. The data was collected and analysed using SPSS software programme for windows (version 16). Chi-square test was applied. Out of 206 visitors, 132 (64.1%) were males and 107 (51.9%) were in the age group of 30-49 years; 183 (88.8%) had heard about swine flu. More than a third of the visitors (38.3%) disclosed that there was a vaccine to prevent swine flu. Majority responded that it could be transmitted by being in close proximity to pigs (49.0%) and by eating pork (51.5%). Newspaper/magazine (64.6%), television (61.7%), and public posters/pamphlets (44.2%) were common sources of information. The present study revealed that doctors/public health workers have played little role in creating awareness in the community. The improved communication between doctors and the community would help to spread correct information about the disease and the role that the community can play in controlling the spread of the disease.

We explored associations between natural mentoring relationship profiles and young adults’ life satisfaction and symptoms of depression via participants’ perceived support from important others accounting for participants’ perceived support and mental health prior to the onset of their natural mentoring relationships. Participants included 396 young adults (57% female; mean age = 30.97, SD = .6), the majority of whom identified as Black or African American (79% Black, 18% White, 3% Biracial). Most participants had completed high school but few participants (13%) had completed degrees from 4-year institutions. We used a latent profile approach to identify natural mentoring relationship profiles and employed structural equation modeling to test our study hypotheses. Slightly over half of study participants (53%) reported the presence of a natural mentor in their lives since the age of 14. Results suggest that natural mentoring relationships characterized by high levels of relational closeness and either extended relationship duration or frequent contact may promote improvements in psychological well-being among mentees over time via greater experiences of social support from important others.

This study was conducted to culturally adapt and validate the EHP-5 in Iran. Methods Using a standard "forward-backward' translation procedure, the English language version of the questionnaire was translated into Persian (Iranian language. Then a sample of 199 women aged 18-50 years completed the questionnaire. To test reliability the internal consistency was assessed by Cronbach's alpha coefficient. Validity was evaluated using known groups comparison. Results The mean age of respondents was 31.4 (SD = 5.4 years. Reliability analysis showed satisfactory result (Cronbach's alpha coefficient = 0.71. The questionnaire discriminated well between sub-groups of women differing in infertility and premenstrual syndrome (PMS in the expected direction. Conclusion This preliminary validation study of the Iranian version of the EHP-5 proved that it is an acceptable, reliable and valid measure of quality of life in endometriosis patients.

The Service of Health Professions of this facility (TO2 of Turin) aimed during the 2010 to devise/develop a new evaluation tool for the new employees , trying to fit them with the profiles set up the previous year. The conceptual model of reference for the construction of working drafts of the grids was inspired by the special insert edition of "L'infermiere" in 2007, a literature review was carried out and a number of internal meeting within 6 of the Service of health Professions were set up. A working group were set up - 93 people - as well as indicators were developed to monitor and implementation of the instruments. Once the drafts of the standard tools were made, working groups started to improve the tools provided under the supervision of a tutor. Finally half way through an evaluation was carried out using a questionnaire. The new template leads a number of problems which were later sorted out also with the support of tutors.

Health-related quality of life and financial burden among patients with multiple endocrine neoplasia type 1 is poorly described. It is not known how financial burden influences health-related quality of life in this population. We hypothesized that the financial burden attributable to multiple endocrine neoplasia type 1 is associated with worse health-related quality of life. United States adults (≥18 years) with multiple endocrine neoplasia type 1 were recruited from the AMENSupport MEN online support group. Patient demographics, clinical characteristics, and financial burden were assessed via an online survey. The instrument Patient-Reported Outcomes Measurement Information System 29-item profile measure was used to assess health-related quality of life. Multivariable linear regression was used to identify significant variables in each Patient-Reported Outcomes Measurement Information System domain. Out of 1,378 members in AMENSupport, our survey link was accessed 449 times (33%). Of 153 US respondents who completed our survey, 84% reported financial burden attributable to multiple endocrine neoplasia type 1. The degree of financial burden had a linear relationship with worse health-related quality of life across all Patient-Reported Outcomes Measurement Information System domains (r = 0.36-0.55, P financial event(s). Borrowing money from friends/family (30%), unemployment (13%), and spending >$100/month out-of-pocket on prescription medications (46%) were associated consistently with impaired health-related quality of life (ß = 3.75-6.77, P times more likely to be unemployed and declare bankruptcy than the US population, respectively. This study characterizes the financial burden in patients with multiple endocrine neoplasia type 1. Individuals with multiple endocrine neoplasia type 1 report a high degree of financial burden, negative financial events, and unemployment. Each of these factors was associated with worse health-related quality of life

Alternate colorectal cancer (CRC) screening and surveillance strategies are needed to pre-select candidates for invasive methods. We compared systemic inflammatory profiles in CRC (n=99), health (n=98), high CRC-risk conditions (n=48) and overt inflammation (n=69) by multiplexed analysis of IL-1β, IL-6, IL-8, FGF-2, G-CSF, GM-CSF, MCP-1, MIP-1α, TNF-α, VEGF-A, and PDGF-B and CEA. Cytokines corresponded with CRC advancement. FGF2, GM-CSF, IL-1β, IL-6, MIP-1α, PDGF-BB, TNF-α, and VEGF-A were higher than in controls already in stage I CRC with FGF2, IL1-β, and MIP-1α higher than in high CRC-risk individuals as well. Cytokine panels devised to differentiate early CRC from controls, adenomas, or inflammatory bowel disease patients (IBD) had good accuracy but only IBD panel had promising specificity at 95% sensitivity.

Traditionally, basal rate profiles in continuous subcutaneous insulin infusion therapy are individually adapted to cover expected insulin requirements. However, whether this approach is indeed superior to a more constant BR profile has not been assessed so far. This study analysed the associations between variability of BR profiles and acute and chronic complications in adult type 1 diabetes mellitus. BR profiles of 3118 female and 2427 male patients from the "Diabetes-Patienten-Verlaufsdokumentation" registry from Germany and Austria were analysed. Acute and chronic complications were recorded 6 months prior and after the most recently documented basal rate. The "variability index" was calculated as variation of basal rate intervals in percent and describes the excursions of the basal rate intervals from the median basal rate. The variability Index correlated positively with severe hypoglycemia (r = .06; p1), hypoglycemic coma (r = .05; p = 0.002), and microalbuminuria (r = 0.05; p = 0.006). In addition, a higher variability index was associated with higher frequency of diabetic ketoacidosis (r = .04; p = 0.029) in male adult patients. Logistic regression analysis adjusted for age, gender, duration of disease and total basal insulin confirmed significant correlations of the variability index with severe hypoglycemia (β = 0.013; p1) and diabetic ketoacidosis (β = 0.012; p = 0.017). Basal rate profiles with higher variability are associated with an increased frequency of acute complications in adults with type 1 diabetes.

Full Text Available The purpose of this study was to evaluate the knowledge and attitudes toward oral health of education and health professionals working in a children care program for handicapped children from 0 to 6 years of age, run by a public municipal institution in Rio de Janeiro. Using a printed questionnaire, 67 professionals (teachers, attendants and health professionals were interviewed. The results were compared to the children's oral hygiene habits, by directly observing their daily nursery routine. Although 97.0% said that oral health could play a part in general health, only 37.3% of the professionals answered correctly on this matter. As for methods for preventing caries, although 92.5% said that they were aware of them, only 17.9% went to the dentist for preventive treatment. Although the majority (81.3% indicated oral hygiene as a way of preventing caries, observation showed that this practice is not always put into effect in the program's day nursery. Regarding when to start toothbrushing in children, 75.0% of the teachers and 94.4% of the health professionals said that they were aware of the need to begin brushing before one year of age, although this reply was given by only 52.5% of the attendants (chi-square, p = 0.006. In view of these results, it was concluded that attitudes toward oral health were not always coherent with the knowledge that these professionals express.

Full Text Available Academic self-concept (ASC is comprised of individual perceptions of one's own academic ability. In a cross-sectional quasi-representative sample of 3,779 German elementary school children in grades 1 to 4, we investigated (a the structure of ASC, (b ASC profile formation, an aspect of differentiation that is reflected in lower correlations between domain-specific ASCs with increasing grade level, (c the impact of (internal dimensional comparisons of one's own ability in different school subjects for profile formation of ASC, and (d the role played by differences in school grades between subjects for these dimensional comparisons. The nested Marsh/Shavelson model, with general ASC at the apex and math, writing, and reading ASC as specific factors nested under general ASC fitted the data at all grade levels. A first-order factor model with math, writing, reading, and general ASCs as correlated factors provided a good fit, too. ASC profile formation became apparent during the first two to three years of school. Dimensional comparisons across subjects contributed to ASC profile formation. School grades enhanced these comparisons, especially when achievement profiles were uneven. In part, findings depended on the assumed structural model of ASCs. Implications for further research are discussed with special regard to factors influencing and moderating dimensional comparisons.

It is increasingly recognized that some patients self-manage in the context of social networks rather than alone. Consumer health information technology (IT) designed to support socially embedded self-management must be responsive to patients' everyday communication practices. There is an opportunity to improve consumer health IT design by explicating how patients currently leverage social media to support health information communication. The objective of this study was to determine types of health information communication patterns that typify Facebook users with chronic health conditions to guide consumer health IT design. Seven hundred participants with type 2 diabetes were recruited through a commercial survey access panel. Cluster analysis was used to identify distinct approaches to health information communication both on and off Facebook. Analysis of variance (ANOVA) methods were used to identify demographic and behavioral differences among profiles. Secondary analysis of qualitative interviews ( n  = 25) and analysis of open-ended survey questions were conducted to understand participant rationales for each profile. Our analysis yielded 7 distinct health information communication profiles. Five of 7 profiles had consistent patterns both on and off Facebook, while the remaining 2 demonstrated distinct practices, with no health information communication on Facebook but some off Facebook. One profile was distinct from all others in both health information communication practices and demographic composition. Rationales for following specific health information communication practices were categorized under 6 themes: altruism, instrumental support, social support, privacy and stigma, convenience, and Facebook knowledge. Facebook has been widely adopted for health information communication; This study demonstrates that Facebook has been widely adopted for health information communication. It also shows that the ways in which patients communicate health

Prosthodontic rehabilitation helps to improve the oral health-related quality of life (OHRQOL). The Liverpool Oral Rehabilitation Questionnaire (LORQ) and Oral Health Impact Profile (OHIP) are specific tools that measure OHRQOL. The primary objective of this study was to assess the impact of oral rehabilitation on patients' OHRQOL following treatment for cancer of oral cavity using LORQ version 3 (LORQv3) and OHIP-14 questionnaire. Secondary objectives were to identify issues specific to oral rehabilitation, patients compliance to prosthetic rehabilitation, the effect of radiation treatment on prosthetic rehabilitation, to achieve meaningful differences over a time before & after prosthetic intervention, to carryout and document specific patient-deprived problem. Seventy-five oral cancer patients were studied. Patients were asked to rate their experience of dental problems before fabrication of prosthesis and after 1 year using LORQv3 and OHIP-14. The responses were compared on Likert scale. Patients reported with extreme problems before rehabilitation. After 1 year of prosthetic rehabilitation, there was improvement noticed in all the domain of LORQv3 and OHIP-14. Complete compliance to the use of prosthetic appliances for 1 year study period was noted. In response to the question no. 40 (LORQv3), only 15 patients who belonged to the obturator group, brought to notice the problems which were not addressed in the LORQv3 questionnaire. The study showed that the oral cancer patients coped well and adapted to near normal oral status after prosthetic rehabilitation. This contributed to the improved overall health-related quality of life.

Immunological profile of HTLV-1-infected patients associated with infectious or autoimmune dermatological disorders.

Jordana Grazziela Alves Coelho-dos-Reis

Full Text Available In the present study, the frequency, the activation and the cytokine and chemokine profile of HTLV-1 carriers with or without dermatological lesions were thoroughly described and compared. The results indicated that HTLV-1-infected patients with dermatological lesions have distinct frequency and activation status when compared to asymptomatic carriers. Alterations in the CD4(+HLA-DR(+, CD8(+ T cell, macrophage-like and NKT subsets as well as in the serum chemokines CCL5, CXCL8, CXCL9 and CXCL10 were observed in the HTLV-1-infected group with skin lesions. Additionally, HTLV-1 carriers with dermatological skin lesions showed more frequently high proviral load as compared to asymptomatic carriers. The elevated proviral load in HTLV-1 patients with infectious skin lesions correlated significantly with TNF-α/IL-10 ratio, while the same significant correlation was found for the IL-12/IL-10 ratio and the high proviral load in HTLV-1-infected patients with autoimmune skin lesions. All in all, these results suggest a distinct and unique immunological profile in the peripheral blood of HTLV-1-infected patients with skin disorders, and the different nature of skin lesion observed in these patients may be an outcome of a distinct unbalance of the systemic inflammatory response upon HTLV-1 infection.

Full Text Available Nowadays, depending on the progress of science and technology, our eating habits have changed. The shape and quality of nutrition is important for human health. Especially, some food components have various effect on central nervous system such as depression, anxiety, sleep, appetite. Food constituents are transported into the central nervous system via the neutral amino acids such as phenylalanine, leucine, isoleucine, tyrosine and valine. Amino acids have an important role in human nutrition. It cannot be synthesized in the body and one of the essential amino acids that must be taken outside, trytophan, is indispensable in human nutrition because of it has the many functions. In recent years, scientific community concentrated on the various functions of L-Trytophan (L-Trp as pioneer in the secretion of the hormones serotonin and melatoninin in the human body. The hormones serotonin and melatonin is responsible for activities such as psychology, sleep, body temperature, blood pressure balance, antioxidant effect, cancer inhibitor, sexuality, autism and circadian rhythms in human body that they are available in various foods such as milk, kefir, yogurt, orange, strawberry, grape, olive oil, walnut, prune, nut, pomegranate, coffee, kiwi and banana. In this study, L-Trp, serotonin and melatonin biosynthesis and metabolism, food profiles and in terms of their physiological and biological effects on human health has been compiled.

While maintenance of a low cardiovascular risk profile is essential for cardiovascular disease (CVD) prevention, few people maintain a low CVD risk profile throughout their life. We studied the association of demographic, lifestyle, psychological factors and family history of CVD with attainment and maintenance of a low risk profile over three subsequent 5-year periods. Measurements of 6390 adults aged 26-65 years at baseline were completed from 1993 to 97 and subsequently at 5-year intervals until 2013. At each wave, participants were categorized into low risk profile (ideal levels of blood pressure, cholesterol and body mass index, non-smoking and no diabetes) and medium/high risk profile (all others). Multivariable-adjusted modified Poisson regression analyses were used to examine determinants of attainment and maintenance of low risk; risk ratios (RR) and 95% confidence intervals (95% CI) were obtained. Generalized estimating equations were used to combine multiple 5-year comparisons. Younger age, female gender and high educational level were associated with higher likelihood of both maintaining and attaining low risk profile (P risk was 9% higher with each 1-unit increment in Mediterranean diet score (RR: 1.09, 95% CI: 1.02-1.16), twice as high with any physical activity versus none (RR: 2.17, 95% CI: 1.16-4.04) and 35% higher with moderate alcohol consumption versus heavy consumption (RR: 1.35, 95% CI: 1.06-1.73). Healthy lifestyle factors such as adherence to a Mediterranean diet, physical activity and moderate as opposed to heavy alcohol consumption were associated with a higher likelihood of attaining a low risk profile. © The Author 2015.

Regions affected by deindustrialisation are often characterised by unfavourable local health profiles. This was the situation in coalfield areas in England, where the scale and suddenness of the job losses in the 1980s and 1990s left these communities experiencing difficult socioeconomic conditions, and associated poor health status. Using data from the Health Survey for England, this paper examines whether poorer health outcomes still characterise coalfield areas today. Findings confirm a 'coalfield health effect' related to limiting long-term illness. With regards to self reported general health and mental health outcomes, results are less clear. The population health profile of coalfield communities is not homogeneous, with some coalfield communities faring worse than others, indicating more localised health issues.

Social Disadvantage, Severe Child Abuse, and Biological Profiles in Adulthood.

Guided by the stress process model and the life course perspective, we hypothesize: (1) that childhood abuse is concentrated, in terms of type and intensity, among socially disadvantaged individuals, and (2) that experiencing serious abuse contributes to poor biological profiles in multiple body systems in adulthood. Data came from the Biomarker subsample of Midlife in the United States (2004-2006). We used latent class analysis to identify distinct profiles of childhood abuse, each reflecting a combination of type and severity. Results indicate that disadvantaged groups, women, and those from disadvantaged families are at greater risk of experiencing more severe and multiple types of abuse. Those with more severe and multifaceted childhood abuse show greater physiological dysregulation. Childhood abuse experiences partially accounted for the social status differences in physiological profiles. Our findings underscore that differential exposure to serious childhood stressors plays a significant role in gender and class inequalities in adult health.

The purpose of this exploratory cross-sectional study was to explore the health-related profile and quality of life among older persons living with and without pain in nursing homes. Ten nursing homes were approached, and 535 older persons were invited to join the study from 2009 to 2011. The nursing home residents' demographic information and information regarding their pain situation and the use of oral analgesic drug and nondrug therapy among the older residents with chronic pain were also collected. Residents' physical health (using the Barthel Activities of Daily Living (ADL) and Elderly Mobility Scores); psychologic health, including happiness, life satisfaction, depression, and loneliness (using the Happiness Scale, the Life Satisfaction Scale, the Geriatric Depression Scale, and the UCLA Loneliness Scale); and quality of life were investigated. Among the 535 nursing home residents, 396 (74%) of them suffered from pain, with mean pain scores of 4.09 ± 2.19, indicating medium pain intensity a remaining 139 (26%) reported no pain. The location of pain was mainly in the knees, back and shoulders. Our results demonstrated that, with the exception of the no-pain group (p nursing home residents' pain affected both their psychologic health, including happiness, life satisfaction, and depression, and their physical quality of life. Nevertheless, only one-half of the older persons with pain used oral analgesic drug or nondrug therapy to relieve their pain. Pain had a significant impact on their mobility and ADL, was positively correlated with happiness and life satisfaction, and was negatively correlated with loneliness and depression. Pain management is a high priority in elderly care; as such, innovative and interdisciplinary strategies are necessary to enhance quality of life particularly for older persons living in nursing homes.

2016-01-01

Energy-efficient technologies have the potential to provide savings to households and utilities, but consumers do not always adopt these innovations over traditional technologies. The ductless heat pump (DHP) is one such technology designed to increase energy efficiency and comfort in space conditioning. DHP adoption by single-family residences in the Pacific Northwest of the United States is investigated by quantifying the effects of utility-provided rebates and expenditures on activities such as advertising and installer training on the number of installations and forecasting installations through 2018. The number of installations is elastic with respect to net installation costs and inelastic with respect to expenditures. Given the proposed rebate budgets, doubling the current rebate is necessary to maximize installations through 2018. - Highlights: • The ductless heat pump (DHP) is an energy-efficient form of space conditioning. • Rebate and marketing programs designed to increase adoptions of DHPs are examined. • Residential adoption of DHPs is sensitive to rebates and tax credits. • Advertising and training have a smaller effect on adoption than rebates.

This article presents an action research project as a method to combine science and practical expertise in order to develop the practices of the health care system. The project aimed at developing mental health promotion in the school community in general and at finding tools for timely help when mental health is at risk. The underlying idea is that mental health is an integral part of health and by promoting general well-being it is also possible to promote and ensure mental health at school. The study was conducted in a Finnish lower secondary school of 446 pupils where the pupils are aged between 12 and 15 years. The initial survey was conducted using the School Well-being Profile, a tool developed by Anne Konu. A well-being questionnaire was used to identify the areas in need of improvement, providing the basis for planning and implementing development measures together with the local actors. The instrument proved to be a usable way of collecting feedback of the well-being of the school environment. As a result of the action research project, the school's physical conditions and social relationships improved and appropriate practices for future problem situations were set.

Saw palmetto extract (SPE) has been widely used for the treatment of lower urinary-tract symptoms secondary to benign prostatic hyperplasia. The mechanisms of pharmacological effects of SPE include the inhibition of 5alpha-reductase, anti-androgenic effects, anti-proliferative effects, and anti-inflammatory effects. Previously, we showed that SPE bound actively to alpha(1)-adrenergic, muscarinic and 1,4-dihydropyridine calcium channel (1,4-DHP) receptors in the prostate and bladder of rats, whereas its active constituents have not been fully clarified. The present investigation is aimed to identify the main active components contained in hexane and diethyl ether extracts of SPE with the use of column chromatography and preparative HPLC. Based on the binding activity with alpha(1)-adrenergic, muscarinic, and 1,4-DHP receptors, both isolated oleic and lauric acids were deduced to be active components. Authentic samples of oleic and lauric acids also exhibited similar binding activities to these receptors as the fatty acids isolated from SPE, consistent with our findings. In addition, oleic and lauric acids inhibited 5alpha-reductase, possibly leading to therapeutic effects against benign prostatic hyperplasia and related lower urinary-tract symptoms.

Determination of the subcritical multiplication curve profile (1/M) as a function of control rod bank position is of paramount importance to the development of a system which allows to foresee and also anticipate determination of criticality of a PWR reactor core. This work aims at determining this profile. For that, the 3D- two group-diffusion equations for a subcritical PWR reactor core with external neutron source is solved for different control rod bank positions. Results obtained are compared with the results from the corresponding eigenvalue problem, in order to verify how the external neutron source interferes with the reactor criticality search. (author)

This study collected and analyzed recent information regarding the sociodemographic profile and career decisions of Australian oral health profession students (earning B.D.Sc. and B.O.H. degrees) and the reasons for their career choice. Data were collected during the 2009-10 academic year via a web-based survey. A total of 829 students participated; the response rates for each oral health course at the seven participating universities ranged from 15.0 percent to 88.7 percent. The respondents had an average age of 21.4 years, ranging from eighteen to fifty-one. The majority of the respondents were female (61.4 percent), single (91.0 percent), and of Asian ethnicity (65.0 percent), and almost half had attended a public secondary school (49.7 percent). Most of the responding students either lived in rented accommodation (44.0 percent) or with their parents (28.6 percent), and 41.5 percent reported having an urban address. Most respondents' fathers (67.2 percent) and mothers (54.8 percent) had completed undergraduate or postgraduate education and were employed in managerial or professional occupations (68.5 percent and 54.9 percent, respectively). Most of the students said they had selected their course in high school (66.8 percent) and were most influenced in their career choice by self-motivation (85.3 percent) and caring for and helping other people (86.6 percent). The majority of the respondents reported wishing to work in a city (51.5 percent), practicing general dentistry (31.8 percent) in either the public or private sector (40.2 percent each). This article provides a preliminary look at the future dental workforce of Australia, identifying issues for further analysis and assisting each university to address current inequalities and challenges.

The health disparities literature has identified a common pattern among middle-aged African Americans that includes high rates of chronic disease along with low rates of psychiatric disorders despite exposure to high levels of cumulative socioeconomic status (SES) risk. The current study was designed to test hypotheses about the developmental precursors to this pattern. Hypotheses were tested with a representative sample of 443 African American youths living in the rural South. Cumulative SES risk and protective processes were assessed at ages 11-13 years; psychological adjustment was assessed at ages 14-18 years; genotyping at the 5-HTTLPR was conducted at age 16 years; and allostatic load (AL) was assessed at age 19 years. A latent profile analysis identified 5 profiles that evinced distinct patterns of SES risk, AL, and psychological adjustment, with 2 relatively large profiles designated as focal profiles: a physical health vulnerability profile characterized by high SES risk/high AL/low adjustment problems, and a resilient profile characterized by high SES risk/low AL/low adjustment problems. The physical health vulnerability profile mirrored the pattern found in the adult health disparities literature. Multinomial logistic regression analyses indicated that carrying an s allele at the 5-HTTLPR and receiving less peer support distinguished the physical health vulnerability profile from the resilient profile. Protective parenting and planful self-regulation distinguished both focal profiles from the other 3 profiles. The results suggest the public health importance of preventive interventions that enhance coping and reduce the effects of stress across childhood and adolescence.

The Japanese Study on Stratification, Health, Income, and Neighborhood (J-SHINE) aims to clarify the complex associations between social factors and health from an interdisciplinary perspective and to provide a database for use in various health policy evaluations. J-SHINE is an ongoing longitudinal panel study of households of adults aged 25-50 years. The wave 1 survey was carried out in 2010 among adults randomly selected from the resident registry of four urban and suburban municipalities in the greater Tokyo metropolitan area, Japan. In 2011, surveys for the participants' spouse/partner and child were additionally conducted. The wave 2 survey was conducted in 2012 for the wave 1 participants and will be followed by the wave 2 survey for spouse/partner and child in 2013. Wave 1 sample sizes were 4357 for wave 1 participants (valid response rate: 31.3%; cooperation rate: 51.8%), 1873 for spouse/partner (response rate: 61.9%), and 1520 for child (response rate: 67.7%). Wave 2 captured 69.0% of wave 1 participants. Information gathered covered socio-demographics, household economy, self-reported health conditions and healthcare utilization, stress and psychological values, and developmental history. A subpopulation underwent physiological (n = 2468) and biomarker (n = 1205) measurements. Longitudinal survey data, including repeated measures of social factors evaluated based on theories and techniques of various disciplines, like J-SHINE, should contribute toward opening a web of causality for society and health, which may have important policy implications for recent global health promotion strategies such as the World Health Organization's Social Determinants of Health approach and the second round of Japan's Healthy Japan 21.

The stability of the n=1 internal kink mode in a tokamak is numerically analyzed for plasmas with a centrally peaked pressure profile. These studies are carried out with the strongly peaked pressure inside the q=1 surface, which is based on the experimentally observed plasmas by means of injections of hydrogen-ice pellets in JT-60 tokamak. The effects of peaked pressure and shaping, i.e., elongation and triangularity, are also studied for JT-60U tokamak. The plasma with the strongly peaked pressure profile has higher critical value of poloidal beta defined within the q=1 surface than that with a parabolic pressure profile. Though the beta limit reduces with the increase of the elongation, the plasma with the peaked pressure profile has larger improvement due to the triangularity than that with the parabolic pressure profile. To access the second stability of the n=1 internal kink mode, the plasma with a flat pressure profile and the large minor radius of the q=1 surface is effective. (author)

In the last few years, bibliometric studies have proliferated, seeking to provide data on world research. This study analyzes the profile of the Brazilian scientific production in the A (H1N1) influenza field between 2009 and 2011. The research was conducted in MEDLINE, SciELO and LILACS databases, selecting papers in which the term "H1N1" and "Brazil" were defined as the main topics. The data were analyzed taking into consideration the Brazilian state and institution in which the articles were produced, the impact factor of the journal and the language. The research revealed 40 documents (27 from MEDLINE, 16 from SciELO and 24 from LILACS). The journal impact factor ranged from 0.0977 to 8.1230. A similar amount of articles were written in English and Portuguese and São Paulo was the most productive state in the country, with 95% of the Brazilian production originating from the Southern and Southeastern regions. Linguistic data indicate that previous efforts made in order to improve the scientific production of Brazilian researchers making their observations attain a broader scientific audience produced results. It is necessary to assess the scientific studies, especially those conducted with public funds, in order to ensure that the results will benefit society.

Full text: NPCIL with 20 operating units and 6 under construction is contributing the power generation of India in a safe and environmental friendly way. Spread across the country, NPCIL units are serving the nation since 25 years with present installed capacity of 4780 MWe. 'Radiation' is a term associated with nuclear power generation and is a concern for public because of the misconceptions related to it. In reality the proper use of radiation is a boon to the society especially in the field of agriculture, industry and in medicine. According to various studies carried out by international scientific groups in areas with highest exposure to radiation, there was not any increase in disease due to direct or biological effects of radiation. More over there is no significant increase in cancer due to working in a nuclear power plant or residing near to it. The Annual Medical examination of all the employees of a nuclear power plant is a statutory requirement as per the Radiation Protection rules of Govt. of India and it is scrutinised by the Atomic Energy Regulatory Board (AERB). Data of the health profile for 16 years period (i.e. 1995-2010) of employees of all units of NPCIL were collected and analysed. Prevalence of major disease like diabetes mellitus, Hypertension, coronary artery disease, respirator disease were comparable to other state-wise or national studies. Anaemia is found to be practically non-existent. Total number of cancer cases from all units for the said 16 years period was 80 (41 amongst radiation workers and 39 in non radiation workers). Average incidence rate and death rate due to cancer in male, female and combined population (both sexes) is less than the respective national average in each category. This health profile analysis of NPCIL employees shows that their health status is well comparable to the other studies conducted elsewhere across the country for general public and they do not show any variation in disease pattern nor do they have

Longitudinal Latent Cognitive Profiles and Psychosocial Well-being in Early Adolescence.

Engaging in exploratory risky behaviors and experiencing poor mental health during early adolescence are important markers for poor health during adulthood. Prior research suggests protective effects from cognition, but less is known about the associations between early childhood cognition and early adolescent psychosocial well-being, as identified by self-esteem, mental health, and exploratory risky behaviors. This article investigates the extent that early adolescent psychosocial well-being at the age of 11 years is associated with patterns of cognitive skills measured across the first decade of a child's life. We used data collected from the four follow-up sweeps of the UK Millennium Cohort Study and utilized latent profile analysis to identify three discernible cognitive profiles (n = 16,899). We find cohort members in low-achieving profiles to be more likely to engage in exploratory risky behaviors-drinking, smoking, and antisocial conduct-and to have poor self-esteem and more problem behaviors, compared with their peers in high-achieving profiles. Socioeconomic and family psychosocial markers considerably attenuated these disadvantages. Understanding which adolescents have adverse psychosocial well-being has implications for the prevention of chronic diseases and for clinical care and policy.

The γ-Aminobutyrate Permease GabP Serves as the Third Proline Transporter of Bacillus subtilis

PutP and OpuE serve as proline transporters when this imino acid is used by Bacillus subtilis as a nutrient or as an osmostress protectant, respectively. The simultaneous inactivation of the PutP and OpuE systems still allows the utilization of proline as a nutrient. This growth phenotype pointed to the presence of a third proline transport system in B. subtilis. We took advantage of the sensitivity of a putP opuE double mutant to the toxic proline analog 3,4-dehydro-dl-proline (DHP) to identify this additional proline uptake system. DHP-resistant mutants were selected and found to be defective in the use of proline as a nutrient. Whole-genome resequencing of one of these strains provided the lead that the inactivation of the γ-aminobutyrate (GABA) transporter GabP was responsible for these phenotypes. DNA sequencing of the gabP gene in 14 additionally analyzed DHP-resistant strains confirmed this finding. Consistently, each of the DHP-resistant mutants was defective not only in the use of proline as a nutrient but also in the use of GABA as a nitrogen source. The same phenotype resulted from the targeted deletion of the gabP gene in a putP opuE mutant strain. Hence, the GabP carrier not only serves as an uptake system for GABA but also functions as the third proline transporter of B. subtilis. Uptake studies with radiolabeled GABA and proline confirmed this conclusion and provided information on the kinetic parameters of the GabP carrier for both of these substrates. PMID:24142252

There are no published data on factors impacting on acute respiratory illness (ARI) among urban Indigenous children. We describe the characteristics and respiratory risk profile of young urban Indigenous children attending an Aboriginal-friendly primary health-care practice. We conducted a cross-sectional analysis of data collected at baseline in a cohort study investigating ARI in urban Indigenous children aged less than 5 years registered with an Aboriginal primary health-care service. Descriptive analyses of epidemiological, clinical, environmental and cultural factors were performed. Logistic regression was undertaken to examine associations between child characteristics and the presence of ARI at baseline. Between February 2013 and October 2015, 180 Indigenous children were enrolled; the median age was 18.4 months (7.7-35), 51% were male. A total of 40 (22%) children presented for a cough-related illness; however, ARI was identified in 33% of all children at the time of enrolment. A total of 72% of children were exposed to environmental tobacco smoke. ARI at baseline was associated with low birthweight (adjusted odds ratio (aOR) 2.54, 95% confidence interval (CI) 1.08-5.94), a history of eczema (aOR 2.67, 95% CI 1.00-7.15) and either having a family member from the Stolen Generation (aOR 3.47, 95% CI 1.33-9.03) or not knowing this family history (aOR 3.35, 95% CI 1.21-9.26). We identified an urban community of children of high socio-economic disadvantage and who have excessive exposure to environmental tobacco smoke. Connection to the Stolen Generation or not knowing the family history may be directly impacting on child health in this community. Further research is needed to understand the relationship between cultural factors and ARI. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Leek (Allium ampeloprasum var. porrum) is consumed as a vegetable throughout the world. However, little is known about the metabolites of leek cultivars, especially those with potentially important beneficial properties for human health. We provide new information for the overall metabolite composition of several leek cultivars grown in Europe by using HPLC-MS and (1) H NMR. The use of a novel CTLS/NMR (constrained total-line-shape nuclear magnetic resonance) approach was found to be capable of reliable quantification, even with overlapping metabolite signals in the (1) H NMR of plant metabolites. Additionally, a new application for leek flavonoids was optimised for HPLC-MS. The total concentration of carbohydrates (glucose, fructose, kestose/nystose and sucrose) and nine amino acids varied by fourfold in leek juice from different cultivars, while the total concentrations of four organic acids were similar in all cultivars. All the quantified flavonols were kaempferol derivatives or quercetin derivatives and threefold differences in flavonol concentrations were detected between cultivars. In this study, various phytochemical profiles were determined for several leek cultivars by (1) H NMR spectroscopy with CTLS combined with HPLC-MS. The wide variation in bioactive compounds among commercial leek cultivars offers promising opportunities for breeders to raise the levels of important biochemical compounds in leek breeding lines, and also provides some objective measure for quality assurance for the leek industry.

Genomic scan reveals loci under altitude adaptation in Tibetan and Dahe pigs.

Directory of Open Access Journals (Sweden)

Kunzhe Dong

Full Text Available High altitude environments are of particular interest in the studies of local adaptation as well as their implications in physiology and clinical medicine in human. Some Chinese pig breeds, such as Tibetan pig (TBP that is well adapted to the high altitude and Dahe pig (DHP that dwells at the moderate altitude, provide ideal materials to study local adaptation to altitudes. Yet, it is still short of in-depth analysis and understanding of the genetic adaptation to high altitude in the two pig populations. In this study we conducted a genomic scan for selective sweeps using FST to identify genes showing evidence of local adaptations in TBP and DHP, with Wuzhishan pig (WZSP as the low-altitude reference. Totally, we identified 12 specific selective genes (CCBE1, F2RL1, AGGF1, ZFPM2, IL2, FGF5, PLA2G4A, ADAMTS9, NRBF2, JMJD1C, VEGFC and ADAM19 for TBP and six (OGG1, FOXM, FLT3, RTEL1, CRELD1 and RHOG for DHP. In addition, six selective genes (VPS13A, GNA14, GDAP1, PARP8, FGF10 and ADAMTS16 were shared by the two pig breeds. Among these selective genes, three (VEGFC, FGF10 and ADAMTS9 were previously reported to be linked to the local adaptation to high altitudes in pigs, while many others were newly identified by this study. Further bioinformatics analysis demonstrated that majority of these selective signatures have some biological functions relevant to the altitude adaptation, for examples, response to hypoxia, development of blood vessels, DNA repair and several hematological involvements. These results suggest that the local adaptation to high altitude environments is sophisticated, involving numerous genes and multiple biological processes, and the shared selective signatures by the two pig breeds may provide an effective avenue to identify the common adaptive mechanisms to different altitudes.

The phytochemistry and bioactivity of wetland macrophytes are underexplored. Plants are known as the natural sources of phytochemical beneficial to health. The objective of this study is to analyze the phytochemical profiles and bioactivities of 10 extracts prepared from different plant parts of wetland macrophytes Hanguana malayana, Ludwigia adscendens and Monochoria hastata. High performance liquid chromatography (HPLC) was used to analyze the phytochemical profile of the extracts. Antioxidant assay such as 2,2-diphenyl-1-picrylhydrazyl, nitric oxide (NO) radical scavenging activity and ferric reducing antioxidant power were performed. Bioactivity assays carried out were anti-lipoxygenase, anti-glucosidase, and iron chelating. Leaf extract of L. adscendens had the highest 2,2-diphenyl-1-picrylhydrazyl (half of maximal effective concentration [EC50] =0.97 mg/mL) and NO (EC50 = 0.31 mg/mL) scavenging activities. The extract also exhibited the highest iron chelating (EC50 = 3.24 mg/mL) and anti-glucosidase (EC50 = 27.5 μg/mL) activities. The anti-glucosidase activity of L. adscendens leaf extract was comparable or superior to those of acarbose, myricetin and quercetin. Correlation between iron chelating and radical scavenging activities among the extracts implies the presence of dual-function phytoconstituents with concurrent iron chelating and radical scavenging activities. HPLC analysis revealed the presence of p-coumaric acid (p-CA), gallic acid (GA) and myricetin in all or most extracts. M. hastata fruit and leaf extracts had the highest p-hydroxybenzoic acid content. Antioxidant and anti-glucosidase activities of the extracts were correlated with p-CA, GA, and myricetin contents. Our study demonstrated that wetland macrophytes H. malayana, L. adscendens and M. hastata are potential sources of health-promoting phytochemicals with potent therapeutically-relevant bioactivities.

To investigate the effects of activated rat hepatic stellate cells (HSCs) on rat Th1/Th2 profile in vitro. Growth and survival of activated HSCs and CD4(+) T lymphocytes cultured alone or together was assessed after 24 or 48 h. CD4(+) T lymphocytes were then cultured with or without activated HSCs for 24 or 48 h and the proportion of Th1 [interferon (IFN)-γ(+)] and Th2 [interleukin (IL)-4(+)] cells was assessed by flow cytometry. Th1 and Th2 cell apoptosis was assessed after 24 h of co-culture using a caspase-3 staining procedure. Differentiation rates of Th1 and Th2 cells from CD4(+) T lymphocytes that were positive for CD25 but did not express IFN-γ or IL-4 were also assessed after 48 h of co-culture with activated HSCs. Galectin-9 expression in HSCs was determined by immunofluorescence and Western blotting. ELISA was performed to assess galectin-9 secretion from activated HSCs. Co-culture of CD4(+) T lymphocytes with activated rat HSCs for 48 h significantly reduced the proportion of Th1 cells compared to culture-alone conditions (-1.73% ± 0.71%; P Th1/Th2 ratio was significantly decreased (-0.44 ± 0.13; P Th1 cells was decreased (-65.71 ± 9.67; P Th1 (12.27% ± 0.99%; P Th1 cell apoptosis rate was significantly higher than in Th2 cells (P Th1 and Th2 cells; however, the increase in the proportion of Th2 cells was significantly higher than that of Th1 cells (1.85% ± 0.48%; P Th1/Th2 profile, inhibiting the Th1 response and enhancing the Th2 response, and this may be a novel pathway for liver fibrogenesis.

The Sickness Impact Profile (SIP) is a multidimensional, behaviorally based measure of the health status that has been successfully used in a wide range of applications. The characteristics of this measure have not been assessed with nursing home residents. The purpose of this study was to assess the feasibility, reliability (internal consistency), validity, and comprehensiveness of the SIP as a measure of the health status of a selected group of nursing home residents. One hundred sixty-eight veterans residing in community and VA nursing homes responded to a questionnaire consisting of the SIP, Index of Activities of Daily Living, Barthel Index, Life Satisfaction Index Z, and the Philadelphia Geriatric Center Morale Scale. In general, the respondents correctly interpreted instructions; reliability and validity were supported; and the SIP was found to provide a comprehensive assessment of physical function. Adding a measure of psychologic well-being to a study protocol involving this population may, however, provide additional useful information regarding this construct.
