    Terttu Heikinheimo

    Full Text Available BACKGROUND: Stroke contributes significantly to disability and mortality in developing countries yet little is known about the determinants of stroke outcomes in such countries. 12% of Malawian adults have HIV/AIDS. It is not known whether having HIV-infection alters the outcome of stroke. The aim of this study was to document the functional outcome and mortality at 1 year of first-ever acute stroke in Malawi. Also to find out if the baseline variables, including HIV-infection, affect the outcome of stroke. METHODS AND FINDINGS: 147 adult patients with first-ever acute stroke were prospectively followed up for 12 months. Conventional risk factors and HIV-infection were assessed at baseline. Stroke severity was evaluated with modified National Institute of Health Stroke Scale (mNIHSS and functional outcome with modified Rankin scale (mRS. Fifty (34% of patients were HIV-seropositive. 53.4% of patients had a poor outcome (severe disability or death, mRS 4-6 at 1 year. Poor outcome was related to stroke severity and female gender but not to presence of HIV-infection. HIV-seropositive patients were younger and had less often common risk factors for stroke. They suffer more often ischemic stroke than HIV-seronegative patients. CONCLUSIONS: Mild stroke and male gender were associated with favourable outcome. HIV-infection is common in stroke patients in Malawi but does not worsen the outcome of stroke. However, it may be a risk factor for ischemic stroke for young people, who do not have the common stroke risk factors. Our results are significant, because stroke outcome in HIV-seropositive patients has not been studied before in a setting such as ours, with very limited resources and a high prevalence of HIV.

    It is not clear which screening examinations are best suited for gastric cancer prevention, especially in patients with atrophic gastritis and intestinal metaplasia. Therefore, we investigated the gastric cancer screening methods and intervals that are performed in clinical practice in an area with a high prevalence of gastric cancer. Eighty-seven physicians voted by keypad and discussed the consistency of endoscopic diagnosis of atrophic gastritis and intestinal metaplasia at the Annual Symposium of the Korean College of Helicobacter and Upper Gastrointestinal Research. Additionally, 100 core members of this academic society were asked via e-mail to complete the questionnaires related to screening strategies for gastric cancer. The most common recommendation for the subjects with intestinal metaplasia was an annual endoscopic follow-up (95.5% vs. 80.4% in the expert and non-expert groups, respectively; P = 0.118). Annual endoscopic follow-up was also the most predominant recommendation for atrophic gastritis (95.5% vs. 76.5%; P = 0.092), regardless of the physicians' endoscopic experience, position, and degree of the hospital. However, the correct answer rate for the diagnosis of normal endoscopic findings was only 16.7 and 14.1% in the expert and non-expert groups, respectively (P = 0.883). The most common practical screening strategy for patients with atrophic gastritis and intestinal metaplasia in Korea was annual endoscopic examination. However, a new program estimating individualized gastric cancer risk might be needed because of the low inter-observer agreement in the endoscopic diagnosis of atrophic gastritis and intestinal metaplasia.

  3. High Prevalence of the BIM Deletion Polymorphism in Young Female Breast Cancer in an East Asian Country.

    Ching-Hung Lin

    Full Text Available A rapid surge of female breast cancer has been observed in young women in several East Asian countries. The BIM deletion polymorphism, which confers cell resistance to apoptosis, was recently found exclusively in East Asian people with prevalence rate of 12%. We aimed to evaluate the possible role of this genetic alteration in carcinogenesis of breast cancer in East Asians.Female healthy volunteers (n = 307, patients in one consecutive stage I-III breast cancer cohort (n = 692 and one metastatic breast cancer cohort (n = 189 were evaluated. BIM wild-type and deletion alleles were separately genotyped in genomic DNAs.Both cancer cohorts consistently showed inverse associations between the BIM deletion polymorphism and patient age (≤35 y vs. 36-50 y vs. >50 y: 29% vs. 22% vs. 15%, P = 0.006 in the consecutive cohort, and 40% vs. 23% vs. 13%, P = 0.023 in the metastatic cohort. In healthy volunteers, the frequencies of the BIM deletion polymorphism were similar (13%-14% in all age groups. Further analyses indicated that the BIM deletion polymorphism was not associated with specific clinicopathologic features, but it was associated with poor overall survival (adjusted hazard ratio 1.71 in the consecutive cohort.BIM deletion polymorphism may be involved in the tumorigenesis of the early-onset breast cancer among East Asians.

    This study examined the association of depression, anxiety, and stress with Type 2 diabetes (T2DM) in Bahrain, an island-country with a very high prevalence of T2DM. This was a cross-sectional study involving administering Depression Anxiety Stress Scales (DASS)-21 structured depression, anxiety, and stress scale to 143 T2DM patients and 132 healthy controls. Higher proportion of T2DM patients were found in the mild-moderate and severe- extremely severe depression (p=0.002), anxiety (pstress (pstress were associated with T2DM after adjusting for all variables, while age was the only significant variable associated with stress. These results suggest a positive contribution of T2DM to increased depressive and/or anxiety and/or stress disorders among the patients examined, thereby recommending counseling for T2DM patients.

    The World Health Organization's (WHO) antiretroviral therapy (ART) guidelines have generally been adopted rapidly and with high fidelity by countries in sub-Saharan Africa. Thus far, however, WHO has not published specific guidance on nutritional care and support for (non-pregnant) adults living with HIV despite a solid evidence base for some interventions. This offers an opportunity for a case study on whether national clinical guidelines in sub-Saharan Africa provide concrete recommendations in the face of limited guidance by WHO. This study, therefore, aims to determine if national HIV treatment guidelines in sub-Saharan Africa contain specific guidance on nutritional care and support for non-pregnant adults living with HIV. We identified the most recent national HIV treatment guidelines in sub-Saharan African countries with English as an official language. Using pre-specified criteria, we determined for each guideline whether it provides guidance to clinicians on each of five components of nutritional care and support for adults living with HIV: assessment of nutritional status, dietary counseling, micronutrient supplementation, ready-to-use therapeutic or supplementary foods, and food subsidies. We found that national HIV treatment guidelines in sub-Saharan Africa generally do not contain concrete recommendations on nutritional care and support for non-pregnant adults living with HIV. Given that decisions on nutritional care and support are inevitably being made at the clinician-patient level, and that clinicians have a relative disadvantage in systematically identifying, summarizing, and weighing up research evidence compared to WHO and national governments, there is a need for more specific clinical guidance. In our view, such guidance should at a minimum recommend daily micronutrient supplements for adults living with HIV who are in pre-ART stages, regular dietary counseling, periodic assessment of anthropometric status, and additional nutritional

  6. Using stool antigen to screen for Helicobacter pylori in immigrants and refugees from high prevalence countries is relatively cost effective in reducing the burden of gastric cancer and peptic ulceration.

    Thomas R Schulz

    Full Text Available OBJECTIVES: Refugees and immigrants from developing countries settling in industrialised countries have a high prevalence of Helicobacter pylori (H. pylori. Screening these groups for H. pylori and use of eradication therapy to reduce the future burden of gastric cancer and peptic ulcer disease is not currently recommended in most countries. We investigated whether a screening and eradication approach would be cost effective in high prevalence populations. METHODS: Nine different screening and follow-up strategies for asymptomatic immigrants from high H. pylori prevalence areas were compared with the current approach of no screening. Cost effectiveness comparisons assumed population prevalence's of H. pylori of 25%, 50% or 75%. The main outcome measure was the net cost for each cancer prevented for each strategy. Total costs of each strategy and net costs including savings from reductions in ulcers and gastric cancer were also calculated. RESULTS: Stool antigen testing with repeat testing after treatment was the most cost effective approach relative to others, for each prevalence value. The net cost per cancer prevented with this strategy was US$111,800 (assuming 75% prevalence, $132,300 (50% and $193,900 (25%. A test and treat strategy using stool antigen remained relatively cost effective, even when the prevalence was 25%. CONCLUSIONS: H. pylori screening and eradication can be an effective strategy for reducing rates of gastric cancer and peptic ulcers in high prevalence populations and our data suggest that use of stool antigen testing is the most cost effective approach.

    Full Text Available Abstract Background Few studies of miners have been carried out in African countries; most are from South Africa, where the working conditions are assumed to be better than in the rest of Africa. Several studies have focused on respiratory disorders among miners, but development workers responsible for creating underground road ways have not been studied explicitly. This is the first study assessing the associations between exposure to dust and quartz and respiratory symptoms among coal mine workers in a manually operated coal mine in Tanzania, focusing on development workers, as they have the highest exposure to coal dust. Methods A cross-sectional study was carried out among 250 production workers from a coal mine. Interviews were performed using modified standardized questionnaires to elicit information on occupational history, demographics, smoking habits and acute and chronic respiratory symptoms. The relationships between current dust exposure as well as cumulative respirable dust and quartz and symptoms were studied by group comparisons as well as logistic regression. Results Workers from the development group had the highest dust exposure, with arithmetic mean of 10.3 mg/m3 for current respirable dust and 1.268 mg/m3 for quartz. Analogous exposure results for mine workers were 0.66 mg/m3 and 0.03 mg/m3, respectively; and for other development workers were 0.88 mg/m3 and 0.10 mg/m3, respectively. The workers from the development section had significantly higher prevalence of the acute symptoms of dry cough (45.7%, breathlessness (34.8% and blocked nose (23.9%. In addition, development workers had significantly more chronic symptoms of breathlessness (17.0% than the mine workers (6.4% and the other production workers (2.4%. The highest decile of cumulative exposure to respirable dust was significantly associated with cough (OR = 2.91, 95% CI 1.06, 7.97 as were cumulative exposure to quartz and cough (OR = 2.87, CI 1.05, 7.88, compared with

    El-Desouki, Mahmoud I.; Sulimani, Riyadh A.

    2007-01-01

    Objective was to determine the prevalence of osteoporosis in healthy Saudi men. We randomly recruited 429 Saudi men from the community. The recruited Saudi men were subjected to an interview to reveal their lifestyle parameters, calcium intake and level of activity. Bone densitometry was assessed at lumbar spine (L-4) and the femoral neck. The dual x-ray absorptiometry (DXA) scan was carried out in the Nuclear Medicine at King Khalid University Hospital, Riyadh, Saudi Arabia from September 2002 to December 2004. The World Health Organization definition of low bone mineral density was used. Poor oral calcium intake and low level of daily activity were noted. The overall prevalence of osteopenia for the lumbar spine in the whole group was 35.7% while osteoporosis was present in 21.4% of the subjects. In the femoral neck, osteopenia was noted in 38% and osteoporosis in 11.4%. When either lumbar spine or femoral neck osteoporosis is used for diagnosis, the prevalence of osteoporosis rises to 23.5%. Within the whole group, osteopenia and osteoporosis were more common in individuals above the age of 50 than those below 50 years old. Low bone mineral density occurs with high frequency in Saudi men. Lumbar spine appears to be affected to a higher degree. The reason for the high prevalence of osteoporosis in Saudi men is unclear. Possible underlying causes include nutritional, life style and genetic factors. (author)

The aim of the present study was to determine the prevalence of COPD in patients with cerebral and/or peripheral artery disease and to assess factors associated with the presence of COPD. Following the diagnosis of cerebral and/or peripheral artery disease by means of duplex sonography, 166 consecutive patients underwent body plethysmography with capillary blood gas analysis. Thereafter, blood tests with determination of different parameters such as lipid profile, inflammatory and coagulation markers were conducted in remaining 136 patients who fulfilled inclusion criteria of the study. Thirty-six out of 136 patients suffered from COPD, mostly in early stages of the disease. Residual volume indicating emphysema was increased (162.9%±55.9% vs 124.5%±37.0%, p<0.05 and diffusion capacity was decreased (55.1%±19.5% vs 75.3%±18.6%, p<0.05 in COPD patients vs non-COPD group. In capillary blood gas analysis, COPD patients had lower partial pressure of oxygen (70.9±11.5 vs 75.2±11.0 mmHg, p<0.05 and higher partial pressure of carbon dioxide (36.8±7.5 vs 34.4±4.4 mmHg, p<0.05 compared with non-COPD individuals. Presence of COPD was associated with predominance of diabetes mellitus, interleukin-8-related systemic neutrophilic inflammation and anemia. In conclusion, COPD is highly prevalent in patients with atherosclerotic artery disease.

    Most halftoning techniques allow screen dots to overlap. They rely on the assumption that the inks are transparent, i.e. the inks do not scatter a significant portion of the light back to the air. However, many special effect inks such as metallic inks, iridescent inks or pigmented inks are not transparent. In order to create halftone images, halftone dots formed by such inks should be juxtaposed, i.e. printed side by side. We propose an efficient juxtaposed color halftoning technique for pla...

    We have investigated a new radiation pressure trap which relies on optical pumping and does not require any magnetic field. It employs six circularly polarized divergent beams and works on the red of a J g →J e = J g + 1 atomic transition with J g ≥1/2. We have demonstrated this trap with cesium atoms from a vapour cell using the 852 nm J g = 4→J e = 5 resonance transition. The trap contained up to 3.10 7 atoms in a cloud of 1/√e radius of 330 μm.

They rely on the assumption that the inks are transparent, i.e., the inks do not scatter a significant portion of the light back to the air. However, many special effect inks, such as metallic inks, iridescent inks, or pigmented inks, are not transparent. In order to create halftone images, halftone dots formed by such inks should be juxtaposed, i.e., printed side by side. We propose an efficient juxtaposed color halftoning technique for placing any desired number of colorant layers side by side without overlapping. The method uses a monochrome library of screen elements made of discrete lines with rational thicknesses. Discrete line juxtaposed color halftoning is performed efficiently by multiple accesses to the screen element library.

    Hepatitis E virus (HEV) is a major cause of acute hepatitis worldwide, primarily transmitted by fecal-oral route. Zoonotic transmission of HEV from HEV-infected pigs (pork) or cows (milk) to human or non-human primate has been confirmed, but the risk of HEV in goat is still rarely assessed. In the present study, stool, blood, tissues, and milk of goat were collected for HEV infection investigation from Dali City of Yunnan Province in China, where raw mutton and goat milk are traditionally consumed. Surprisingly, a high prevalence of HEV infection in goat was found. Phylogenetic analysis revealed that all HEV isolates from goat belong to genotype 4 and subtype 4h, and shared a high similarity homology (>99.6%) with HEV isolated from human, swine, and cows in the same area. Results suggested that goats are a previously unrecognized HEV host. © 2017 Wiley Periodicals, Inc.

    Refractory coeliac disease (RCD) is thought to be a rare disorder, but the accurate prevalence is unknown. We aimed to identify the prevalence of and the risk factors for developing RCD in a Finnish population where the clinical detection rate of coeliac disease is high. The study involved 11 hospital districts in Finland where the number of treated RCD patients (n = 44), clinically diagnosed coeliac disease patients (n = 12 243) and adult inhabitants (n = 1.7 million) was known. Clinical characteristics at diagnosis of coeliac disease between the RCD patients and patients with uncomplicated disease were compared. The prevalence of RCD was 0.31% among diagnosed coeliac disease patients and 0.002% in the general population. Of the enrolled 44 RCD patients, 68% had type I and 23% type II; in 9% the type was undetermined. Comparing 886 patients with uncomplicated coeliac disease with these 44 patients that developed RCD later in life, the latter were significantly older (median 56 vs 44 years, P coeliac disease. Patients with evolving RCD had more severe symptoms at the diagnosis of coeliac disease, including weight loss in 36% (vs. 16%, P = 0.001) and diarrhoea in 54% (vs. 38%, P = 0.050). Refractory coeliac disease is very rare in the general population. Patients of male gender, older age, severe symptoms or seronegativity at the diagnosis of coeliac disease are at risk of future refractory coeliac disease and should be followed up carefully. © 2014 John Wiley & Sons Ltd.

    Genetic and environmental factors are responsible for variations in the frequency of osteoporosis. Prevalence of osteoporosis in Mapuche women (native Chileans) is unknown. To assess the prevalence and risk factors for osteoporosis in Mapuche women. A random sample of 95 asymptomatic postmenopausal Mapuche females, stratified by age, was studied. Women with diseases or medications that could interfere with calcium metabolism were excluded. Spine and femoral neck bone mass density was determined using a Lunar DPX Alpha densitometer. Seventeen percent of women had normal bone mineral density in both spine and femoral neck. In the spine, 25.3% had a normal bone mineral density, 17.9% had osteopenia and 56.8% had osteoporosis. In the femoral neck, 34.7% had a normal bone mineral density, 57.9% had osteopenia, and 7.4% had osteoporosis. There was a positive correlation between bone mineral density and body mass index. Women with more than one hour per day of physical activity, had a significantly lower proportion of osteopenia or osteoporosis. No association between bone mineral density and parity or calcium intake, was observed. There is a high prevalence of osteopenia and osteoporosis among Mapuche women. Osteoporosis was associated with low body mass index.

    To determine the prevalence of gonioscopically narrow anterior chamber angles in a Filipino-American clinic population. The records of 122 consecutive, new, self-declared Filipino-American patients examined in a comprehensive ophthalmology clinic in Vallejo, California were reviewed retrospectively. After exclusion, 222 eyes from 112 patients remained for analysis. Data were collected for anterior chamber angle grade as determined by gonioscopy (Shaffer system), age, sex, manifest refraction (spherical equivalent), intraocular pressure, and cup-to-disk ratio. Data from both eyes of patients were included and modeled using standard linear mixed-effects regression. As a comparison, data were also collected from a group of 30 consecutive White patients from the same clinic. After exclusion, 50 eyes from 25 White patients remained for comparison. At least 1 eye of 24% of Filipino-American patients had a narrow anterior chamber angle (Shaffer grade ≤ 2). Filipino-American angle grade significantly decreased with increasingly hyperopic refraction (P=0.007) and larger cup-to-disk ratio (P=0.038). Filipino-American women had significantly decreased angle grades compared with men (P=0.028), but angle grade did not vary by intraocular pressure or age (all, P≥ 0.059). Narrow anterior chamber angles are highly prevalent in Filipino-American patients in our clinic population.

    The prevalence of infection by Anaplasma spp. (including Anaplasma phagocytophilum) was determined using blood smear microscopy and PCR through screening of small ruminant blood samples collected from seven regions of Morocco. Co-infections of Anaplasma spp., Babesia spp, Theileria spp. and Mycoplasma spp. were investigated and risk factors for Anaplasma spp. infection assessed. A total of 422 small ruminant blood samples were randomly collected from 70 flocks. Individual animal (breed, age, tick burden and previous treatment) and flock data (GPS coordinate of farm, size of flock and livestock production system) were collected. Upon examination of blood smears, 375 blood samples (88.9%) were found to contain Anaplasma-like erythrocytic inclusion bodies. Upon screening with a large spectrum PCR targeting the Anaplasma 16S rRNA region, 303 (71%) samples were found to be positive. All 303 samples screened with the A. phagocytophilum-specific PCR, which targets the msp2 region, were found to be negative. Differences in prevalence were found to be statistically significant with regard to region, altitude, flock size, livestock production system, grazing system, presence of clinical cases and application of tick and tick-borne diseases prophylactic measures. Kappa analysis revealed a poor concordance between microscopy and PCR (k = 0.14). Agreement with PCR is improved by considering microscopy and packed cell volume (PCV) in parallel. The prevalence of double infections was found to be 1.7, 2.5 and 24% for Anaplasma-Babesia, Anaplasma-Mycoplasma and Anaplasma-Theileria, respectively. Co-infection with three or more haemoparasites was found in 1.6% of animals examined. In conclusion, we demonstrate the high burden of anaplasmosis in small ruminants in Morocco and the high prevalence of co-infections of tick-borne diseases. There is an urgent need to improve the control of this neglected group of diseases. © 2015 Blackwell Verlag GmbH.

    Large parts of African and American countries are colonized by Mansonella, a very common but poorly described filarial nematode. Bloodsucking flies of the genus Culicoides are suspected to be the vector of Mansonella perstans, but no study in Senegal has confirmed that Culicoides can transmit the parasite. Designed specific real-time quantitative polymerase chain reaction (qPCR) can be used to identify microfilaria in stained blood smears. This study was performed in July and December 2010 in the southeastern Senegal, which is known to be endemic for M. perstans. We analyzed 297 blood smears from febrile and afebrile resident people by qPCR. The global prevalence of M. perstans was approximately 14.5% in both febrile and afebrile individuals. The age group of > 30 years had the highest prevalence (22.0%). No Culicoides among 1,159 studied specimens was positive for M. perstans and its vector in Senegal still requires identification.

    2015-08-07

    To describe the pattern of drug use among men who have sex with men (MSM) living in Spain and its association with sexual risk practices. The European MSM Internet Survey was implemented in 2010 in 38 European countries on websites for MSM and collected data on sociodemographics, sexual behavior, and other sexual health variables. The association between unprotected anal intercourse (UAI) with casual partners and drug consumption was evaluated using multivariate logistic regression models. Among the 13,111 participants, most consumed drugs were cannabis (30.1%), popper (28.4%) and cocaine (18.7%). The risk of UAI with casual partners was 1.5 among those who had used drugs in relation to the other participants. The proportion of MSM who had injected drugs at least once in life was 2.5%, and 1.4% in the last 12 months. The prevalence of UAI with casual partners (53.4%), human immunodeficiency virus (HIV) (23%), hepatitis C (8.2%) and sexually transmitted infections (STI) (15.8%) was higher in MSM injectors related to those who had not used injected drugs (P<.05). The results of this study confirm a high prevalence of drug use in MSM and their relationship to sexual risk behavior. Although the use of injected drugs in MSM is a minority, this group reported a higher level of sexual risk behaviors, self-reported HIV, hepatitis C and other STI.

    Neurocysticercosis is a common helminthic infection of the central nervous system and an important cause of adult-onset epilepsy in endemic countries. However, few studies have examined associations between neurologic symptoms, serology and radiographic findings on a community-level. We conducted a population-based study of resident's ≥2 years old in a highly endemic village in Peru (pop. 454). We applied a 14 -question neurologic screening tool and evaluated serum for antibodies against Taenia solium cysticercosis using enzyme-linked immunoelectrotransfer blot (LLGP-EITB). We invited all residents ≥18 years old to have non-contrast computerized tomography (CT) of the head. Of the 385 residents who provided serum samples, 142 (36.9%) were seropositive. Of the 256 residents who underwent CT scan, 48 (18.8%) had brain calcifications consistent with NCC; 8/48 (17.0%) reported a history of headache and/or seizures. Exposure to T. solium is very common in this endemic community where 1 out of 5 residents had brain calcifications. However, the vast majority of people with calcifications were asymptomatic. This study reports a high prevalence of NCC infection in an endemic community in Peru and confirms that a large proportion of apparently asymptomatic residents have brain calcifications that could provoke seizures in the future.

    Full Text Available Many children in low- and middle-income countries may have inadequate intake of vitamin B12 and folate; data confirming these inadequacies are limited. We used biochemical, demographic, behavioral and anthropometric data to describe the folate and vitamin B12 concentrations among six- to 23-month-old Nepalese children. Vitamin B12 (serum B12 < 150 pmol/L and folate deficiencies (red blood cell (RBC folate < 226.5 nmol/L were assessed. We used logistic regression to identify predictors of vitamin B12 deficiency. The vitamin B12 geometric mean was 186 pmol/L; 30.2% of children were deficient. The mean RBC folate concentration was 13,612 nmol/L; there was no deficiency. Factors associated with vitamin B12 deficiency included: (a age six to 11 months (adjusted odds ratio (aOR 1.51; 95% confidence interval (CI: 1.18, 1.92 or 12–17 months (aOR 1.38; 95% CI: 1.10, 1.72 compared to 18–23 months; (b being stunted (aOR 1.24; 95% CI: 1.03, 1.50 compared to not being stunted; (c and not eating animal-source foods (aOR 1.85; 95% CI: 1.42, 2.41 compared to eating animal-source foods the previous day. There was a high prevalence of vitamin B12 deficiency, but no folate deficiency. Improving early feeding practices, including the consumption of rich sources of vitamin B12, such as animal-source foods and fortified foods, may help decrease deficiency.

    In a district of Japanese pear cultivators, a questionnaire survey and an IgE antibody survey were conducted on the pollinosis. A high prevalence of 36.3 percent of the farmers complained of pollinosis symptoms. By the IgE antibody survey, the symptoms were found to be related to the airborne pollens in the orchard.

  9. Intuitive Face Judgments Rely on Holistic Eye Movement Pattern

    Laura F. Mega

    2017-06-01

    Full Text Available Non-verbal signals such as facial expressions are of paramount importance for social encounters. Their perception predominantly occurs without conscious awareness and is effortlessly integrated into social interactions. In other words, face perception is intuitive. Contrary to classical intuition tasks, this work investigates intuitive processes in the realm of every-day type social judgments. Two differently instructed groups of participants judged the authenticity of emotional facial expressions, while their eye movements were recorded: an ‘intuitive group,’ instructed to rely on their “gut feeling” for the authenticity judgments, and a ‘deliberative group,’ instructed to make their judgments after careful analysis of the face. Pixel-wise statistical maps of the resulting eye movements revealed a differential viewing pattern, wherein the intuitive judgments relied on fewer, longer and more centrally located fixations. These markers have been associated with a global/holistic viewing strategy. The holistic pattern of intuitive face judgments is in line with evidence showing that intuition is related to processing the “gestalt” of an object, rather than focusing on details. Our work thereby provides further evidence that intuitive processes are characterized by holistic perception, in an understudied and real world domain of intuition research.

  11. Maladies reliées aux loisirs aquatiques

    Sanborn, Margaret; Takaro, Tim

    2013-01-01

    Résumé Objectif Passer en revue les facteurs de risque, la prise en charge et la prévention des maladies reliées aux loisirs aquatiques en pratique familiale. Sources des données Des articles originaux et de synthèse entre janvier 1998 et février 2012 ont été identifiés à l’aide de PubMed et des expressions de recherche en anglais water-related illness, recreational water illness et swimmer illness. Message principal Il y a un risque de 3 % à 8 % de maladies gastrointestinales (MGI) après la baignade. Les groupes à risque élevé de MGI sont les enfants de moins de 5 ans, surtout s’ils n’ont pas été vaccinés contre le rotavirus, les personnes âgées et les patients immunodéficients. Les enfants sont à plus grand risque parce qu’ils avalent plus d’eau quand ils nagent, restent dans l’eau plus longtemps et jouent dans l’eau peu profonde et le sable qui sont plus contaminés. Les adeptes des sports dans lesquels le contact avec l’eau est abondant comme le triathlon et le surf cerf-volant sont aussi à risque élevé et même ceux qui s’adonnent à des activités impliquant un contact partiel avec l’eau comme la navigation de plaisance et la pêche ont un risque de 40 % à 50 % fois plus grand de MGI par rapport à ceux qui ne pratiquent pas de sports aquatiques. Il y a lieu de faire une culture des selles quand on soupçonne une maladie reliée aux loisirs aquatiques et l’échelle clinique de la déshydratation est utile pour l’évaluation des besoins de traitement chez les enfants affectés. Conclusion Les maladies reliées aux loisirs aquatiques est la principale cause de MGI durant la saison des baignades. La reconnaissance que la baignade est une source importante de maladies peut aider à prévenir les cas récurrents et secondaires. On recommande fortement le vaccin contre le rotavirus chez les enfants qui se baignent souvent.

  12. Robust Sensing of Approaching Vehicles Relying on Acoustic Cues

    Mitsunori Mizumachi

    2014-05-01

    Full Text Available The latest developments in automobile design have allowed them to be equipped with various sensing devices. Multiple sensors such as cameras and radar systems can be simultaneously used for active safety systems in order to overcome blind spots of individual sensors. This paper proposes a novel sensing technique for catching up and tracking an approaching vehicle relying on an acoustic cue. First, it is necessary to extract a robust spatial feature from noisy acoustical observations. In this paper, the spatio-temporal gradient method is employed for the feature extraction. Then, the spatial feature is filtered out through sequential state estimation. A particle filter is employed to cope with a highly non-linear problem. Feasibility of the proposed method has been confirmed with real acoustical observations, which are obtained by microphones outside a cruising vehicle.

  13. Intermediation in Foreign Trade: When do Exporters Rely on Intermediaries?

    2005-01-01

    The paper explores the question of why trade intermediaries (TIs) are frequently used as agents for exports to some countries but not to others. First, we adapt a standard intra-industry trade model with variable export costs (e.g. transport) and fixed export costs (e.g. market access) to include...... a TI that is able to pool market access cost. This framework suggests explanatory factors for the TI share in a country's exports, which are largely in line with the literature. Second, we test these explanatory factors with a new data set based on French customs information. The paper finds that: (i......) higher market access costs increase the TI share, (ii) smaller export markets feature a larger TI share, (iii) network effects are important determinants of trade intermediation....

  15. da Vinci decoded: does da Vinci stereopsis rely on disparity?

    Tsirlin, Inna; Wilcox, Laurie M; Allison, Robert S

    2012-11-01

    In conventional stereopsis, the depth between two objects is computed based on the retinal disparity in the position of matching points in the two eyes. When an object is occluded by another object in the scene, so that it is visible only in one eye, its retinal disparity cannot be computed. Nakayama and Shimojo (1990) found that a precept of quantitative depth between the two objects could still be established for such stimuli and proposed that this precept is based on the constraints imposed by occlusion geometry. They named this and other occlusion-based depth phenomena "da Vinci stereopsis." Subsequent research found quantitative depth based on occlusion geometry in several other classes of stimuli grouped under the term da Vinci stereopsis. However, Nakayama and Shimojo's findings were later brought into question by Gillam, Cook, and Blackburn (2003), who suggested that quantitative depth in their stimuli was perceived based on conventional disparity. In order to understand whether da Vinci stereopsis relies on one type of mechanism or whether its function is stimulus dependent we examine the nature and source of depth in the class of stimuli used by Nakayama and Shimojo (1990). We use three different psychophysical and computational methods to show that the most likely source for depth in these stimuli is occlusion geometry. Based on these experiments and previous data we discuss the potential mechanisms responsible for processing depth from monocular features in da Vinci stereopsis.

  16. Human children rely more on social information than chimpanzees do.

    van Leeuwen, Edwin J C; Call, Josep; Haun, Daniel B M

    2014-11-01

    Human societies are characterized by more cultural diversity than chimpanzee communities. However, it is currently unclear what mechanism might be driving this difference. Because reliance on social information is a pivotal characteristic of culture, we investigated individual and social information reliance in children and chimpanzees. We repeatedly presented subjects with a reward-retrieval task on which they had collected conflicting individual and social information of equal accuracy in counterbalanced order. While both species relied mostly on their individual information, children but not chimpanzees searched for the reward at the socially demonstrated location more than at a random location. Moreover, only children used social information adaptively when individual knowledge on the location of the reward had not yet been obtained. Social information usage determines information transmission and in conjunction with mechanisms that create cultural variants, such as innovation, it facilitates diversity. Our results may help explain why humans are more culturally diversified than chimpanzees. © 2014 The Author(s) Published by the Royal Society. All rights reserved.

  17. Clustered Regularly Interspaced Short Palindromic Repeats Are emm Type-Specific in Highly Prevalent Group A Streptococci.

    2015-01-01

    Clustered regularly interspaced short palindromic repeats (CRISPR) are the bacterial adaptive immune system against foreign nucleic acids. Given the variable nature of CRISPR, it could be a good marker for molecular epidemiology. Group A streptococcus is one of the major human pathogens. It has two CRISPR loci, including CRISPR01 and CRISPR02. The aim of this study was to analyze the distribution of CRISPR-associated gene cassettes (cas) and CRISPR arrays in highly prevalent emm types. The cas cassette and CRISPR array in two CRISPR loci were analyzed in a total of 332 strains, including emm1, emm3, emm4, emm12, and emm28 strains. The CRISPR type was defined by the spacer content of each CRISPR array. All strains had at least one cas cassette or CRISPR array. More than 90% of the spacers were found in one emm type, specifically. Comparing the consistency between emm and CRISPR types by Simpson's index of diversity and the adjusted Wallace coefficient, CRISPR01 type was concordant to emm type, and CRISPR02 showed unidirectional congruence to emm type, suggesting that at least for the majority of isolates causing infection in high income countries, the emm type can be inferred from CRISPR analysis, which can further discriminate isolates sharing the same emm type.

  18. [Scope of the latest RE-LY substudies: clinical implications].

    Ruiz-Giménez Arrieta, N

    2012-03-01

    The approval of the use of dabiatran in stroke prevention in patients with nonvalvular atrial fibrilation (NVAF) is based on the results of the RE-LY (Randomized Evaluation of Long-Term Anticoagulation Therapy) trial, one of the largest studies to date in this entity. In this trial, dabigatran showed similar safety and efficacy to warfarin in primary and secondary prevention of stroke in patients with AF. At a dose of 150 mg twice daily, dabigatran was superior to warfarin in the prevention of stroke or systemic embolism and the 110 mg dose twice daily showed similar efficacy and greater safety, given the lower incidence of hemorrhage. These results were consistently found in the various subanalyses, with some slight differences of interest for clinical practice. The ideal candidates for dabiatran are patients with NVAF suitable for cardioversion, who require short periods of anticoagulation, patients in remote geographical areas with difficulty in achieving good anticoagulation control or good control with anti-vitamin K treatment due to IRN fluctuations, and patients with a low risk of hemorrhage and a CHADS score ≥ 3 and/or with prior stroke, whenever there are no contraindications. The choice of dabigatran dose should be evaluated according to the patient's individual characteristics (caution must be exercised when prescribing this drug in the elderly and in renal insufficiency) and embolic and/or hemorrhagic risk. Studies of the long-term safety of this drug, pharmacoeconomic analyses in Spain and post-commercialization pharmacovigilance data are required before the definitive uses of this drug can be established.

    The cause of zoonotic schistosomiasis in the Philippines is Schistosoma japonicum, which infects up to 46 mammalian hosts, including humans and bovines. In China, water buffaloes have been identified as major reservoir hosts for schistosomiasis japonica, contributing up to 75% of human transmission. In the Philippines, water buffaloes (carabao; Bubalus bubalis carabanesis) have, historically, been considered unimportant reservoirs. We therefore revisited the possible role of bovines in schistosome transmission in the Philippines, using the recently described formalin-ethyl acetate sedimentation (FEA-SD) technique and a qPCR assay to examine fecal samples from 153 bovines (both carabao and cattle) from six barangays in Northern Samar. A high prevalence of S. japonicum was found using qPCR and FEA-SD in both cattle (87.50% and 77.08%, respectively) and carabao (80.00% and 55.24%, respectively). The average daily egg output for each bovine was calculated at 195,000. High prevalence and infection intensity of F. gigantica was also found in the bovines by qPCR and FEA-SD (95.33% and 96.00%, respectively). The identification of bovines as major reservoir hosts for S. japonicum transmission suggests that bovine treatment and/or vaccination, as one becomes available, should be included in any future control program that aims to reduce the disease burden due to schistosomiasis in the Philippines.

    Full Text Available Objectives. Prevalence of hypertension has not been studied in the Ethiopian HIV-infected population, which represents 60% of the patients in our AIDS unit. Our aim was to identify risk factors and characterize the prevalence of hypertension in the population monitored at our unit. Methods. A retrospective chart review categorized subjects according to their blood pressure levels. Hypertension prevalence was determined and stratified according to variables perceived to contribute to elevated blood pressure. Results. The prevalence of hypertension in our study population was significantly higher compared to the general population (53% versus 20%, P<0.0001 and was associated with known risk factors and not with patients’ viral load and CD4 levels. Ethiopian HIV-infected adults had a prominently higher rate of blood pressure rise over time as compared to non-Ethiopians (P=0.016. Conclusions. The high prevalence of hypertension in this cohort and the rapid increase in blood pressure in Ethiopians are alarming. We could not attribute high prevalence to HIV-related factors and we presume it is part of the metabolic syndrome. The lifelong cardiovascular risk associated with HIV infection mandates hypertension screening and close monitoring in this population.

    2017-01-01

    Full Text Available Madagascar is a geographically isolated country considered a biodiversity hotspot with unique genomics. Both the low-income and the geographical isolation represent risk factors for the development of diabetes. During a humanitarian health campaign conducted in Ambanja, a rural city in the northern part of Madagascar, we identified 42 adult subjects with diabetes and compared their features to 24 randomly enrolled healthy controls. 42.9% (n=18 of diabetic subjects showed HbA1c values ≥ 9.0%. Unexpectedly, waist circumference and BMI were similar in people with diabetes and controls. Different from the healthy controls, diabetic subjects showed a low prevalence of obesity (5.7% versus 30%, p=0.02. Accordingly, we found a high prevalence of autoimmune diabetes as 12% of people with diabetes showed positivity for the autoantibody against glutamic acid decarboxylase. Diabetic subjects with positive autoantibody had higher HbA1c values (11.3 ± 4.1% versus 8.3 ± 2.6%, p=0.03 compared to diabetic subjects with negative autoantibody. In conclusion, here we describe the presence of diabetes and its features in a rural area of Northern Madagascar, documenting poor glycaemic control and a high prevalence of autoimmune diabetes. These data highlight that the diabetes epidemic involves every corner of the world possibly with different patterns and features.

    This study aimed to: 1) evaluate the prevalence of cranial asymmetry (positional plagiocephaly) in infants with neonatal brachial plexus palsy (NBPP); 2) examine the association of patient demographics, arm function, and NBPP-related factors to positional plagiocephaly; and 3) determine percentage of spontaneous recovery from positional plagiocephaly and its association with arm function. Infants plagio group), including infants with resolved positional plagiocephaly (plagio-resolved subgroup); and 2) those who never had positional plagiocephaly (non-plagio group). Standard statistics were applied. Eighteen of 28 infants (64%) had positional plagiocephaly. Delivery type might be predictive for plagiocephaly. Infants in the non-plagio group exhibited more active range of motion than infants in the plagio group. All other factors had no significant correlations. A high prevalence of positional plagiocephaly exists among the NBPP population examined. Parents and physicians should encourage infants to use their upper extremities to change position and reduce chance of cranial asymmetry.

    This study aimed to evaluate the prevalence of carbapenemase-producing Enterobacteriaceae in Luanda, Angola. A total of 157 rectal samples were collected from children visiting a pediatric hospital in Luanda in March 2015. Fifty-seven imipenem-nonsusceptible enterobacterial isolates were recovered, most of which were non-clonally related. The blaOXA-181 (50/57) and blaNDM-1 (7/57) carbapenemase genes were identified. Notably, OXA-181-producing Escherichia coli isolates rarely coproduced extended-spectrum β-lactamases and consequently remained susceptible to broad-spectrum cephalosporins. The blaOXA-181 gene was always located on an IncX3 plasmid, while the blaNDM-1 gene was located on either IncFIA or IncA/C plasmids. The study identified a high prevalence of OXA-181 among hospitalized children in Angola. Copyright © 2016, American Society for Microbiology. All Rights Reserved.

  7. High Prevalence of Co-Infections by Invasive and Non-Invasive Chlamydia trachomatis Genotypes during the Lymphogranuloma Venereum Outbreak in Spain.

    Mario Rodriguez-Dominguez

    Full Text Available The evolution of Chlamydia trachomatis is mainly driven by recombination events. This fact can be fuelled by the coincidence in several European regions of the high prevalence of non-invasive urogenital genotypes and lymphogranuloma venereum (LGV outbreaks. This scenario could modify the local epidemiology and favor the selection of new C. trachomatis variants. Quantifying the prevalence of co-infection could help to predict the potential risk in the selection of new variants with unpredictable results in pathogenesis or transmissibility. In the 2009-2013 period, 287 clinical samples with demonstrated presence of C. trachomatis were selected. They were divided in two groups. The first group was constituted by 137 samples with C. trachomatis of the LGV genotypes, and the second by the remaining 150 samples in which the presence of LGV genotypes was previously excluded. They were analyzed to detect the simultaneous presence of non-LGV genotypes based on pmpH and ompA genes. In the first group, co-infections were detected in 10.9% of the cases whereas in the second group the prevalence was 14.6%, which is the highest percentage ever described among European countries. Moreover, bioinformatic analyses suggested the presence among men who have sex with men of a pmpH-recombinant variant, similar to strains described in Seattle in 2002. This variant was the result of genetic exchange between genotypes belonging to LGV and members of G-genotype. Sequencing of other genes, phylogenetically related to pathotype, confirmed that the putative recombinant found in Madrid could have a common origin with the strains described in Seattle. Countries with a high prevalence of co-infections and high migration flows should enhance surveillance programs in at least their vulnerable population.

    The aim of the study was to characterise the incidence, type and presentation of tuberculosis in pregnancy over a 5-year period in women booked for antenatal care in a District General Hospital located in a high prevalence area in London. We also aimed to identify any problems and difficulties in the diagnosis and management of tuberculosis associated with pregnancy. Retrospective review of computer records and hospital notes over a period of 5 years from January 1997 to December 2001. Demographic and clinical data were collected for all the cases identified. All women with tuberculosis who conceived on antituberculous treatment, or had onset of symptoms or diagnosis made in pregnancy or the immediate postpartum period (6 weeks), and booked for antenatal care at a District General Hospital located in an area of high prevalence for tuberculosis (52.2 per 100,000 population in Ealing, Hammersmith and Hounslow Health authority according to the National Tuberculosis Survey of England and Wales in 1998). Thirty-two women were identified over the 5-year period, giving an incidence of 252/100,000 deliveries. The number of cases increased from 3 in 1997 to 10 in each of 2000 and 2001. All of these women were from ethnic minorities and 88% of them were immigrants with the median interval from arrival in UK being 2 years. Fifty-three percent were diagnosed with extrapulmonary tuberculosis, 38% with pulmonary tuberculosis and 9% had both. The median duration of symptoms prior to presentation was 31 days (being longer in women with extrapulmonary tuberculosis); the longest was 10 years. The median interval from presentation of symptoms to diagnosis was 32 days and the majority of women started treatment immediately. The commonest reason for a delay in diagnosis was late presentation (52%), followed by non-specific symptoms (in 38%). There was a trend towards late presentation among recent immigrants (odds ratio 2.14, 95% confidence interval 0.44-10.53) and those having

    The assessment of country risk is of crucial importance for both developing countries and international lenders and investors. Many existing country risk approaches are opaque and heavily rely on subjective choices. In general, they lack a theoretical basis. To assess country risk, we use the Merton

    In China, the prevalence of overweight and obesity appears to be increasing at unacceptable levels among young people living in major cities undergoing rapid economic growth. To report the prevalence of overweight and obesity among Shanghai inner city youth using the recently published International Obesity Task Force (IOTF) Asian definition. Secondary analysis of children aged 8-15 years who participated in the Shanghai Schools' Physical Fitness Examinations, a representative school-based survey. Height and weight were measured and body mass index (kg/m(2)) was calculated. The prevalence of overweight and obesity was determined using the IOTF children's BMI cut-points for Asian populations, equivalent to an adult BMI of 23 g/m(2) (overweight) and 27 kg/m(2) (obese). The prevalence of combined overweight and obesity was 49.1% for boys and 30.8% for girls aged 8-15-years. Almost one-in-five boys were obese, compared with 8.4% of girls. In boys the prevalence of overweight appeared to increase from age 10 years. The high prevalence of combined overweight and obesity among urban Chinese youth, especially among boys, requires immediate health promotion intervention.

    2016-01-01

    Full Text Available The role of Human Papillomavirus (HPV in colorectal carcinogenesis remains elusive. Based on the high incidence of HPV-associated malignancies among Puerto Rican Hispanics, this study aimed to assess the prevalence of HPV infection and viral integration in colorectal tissues in order to evaluate its putative role in colorectal cancer (CRC. In this case-control study, the prevalence of HPV infection in CRC (cases n = 45 and normal colon mucosa from cancer-free subjects (controls n = 36 was assessed by a nested PCR strategy. HPV-16 genotyping was performed in HPV-positive tissues and the physical status of the HPV-16 genome was determined by E2 detection. HPV was detected in 19 of 45 (42.2% CRC cases (mean age 61.1 ± 10.7 years, 24 males and in 1 of 36 (2.8% controls (mean age 60.9 ± 9.6 years, 24 males with an OR = 25.58 (95% CI 3.21 to 203.49. HPV-16 was detected in 63.2% of the HPV-positive colorectal tumors; genome integration was observed in all HPV-16 positive cases. This is the first report showing the high prevalence of HPV infections in Caribbean Hispanic colorectal tumors. Despite evidence of HPV integration into the host genome, further mechanistic analysis examining HPV oncoprotein expression and the putative role of these oncoproteins in colorectal carcinogenesis is warranted.

    2010-01-01

    Loeys-Dietz syndrome (LDS) is a connective tissue disease caused by mutations in the genes encoding the transforming growth factor-β receptor (TGFBR). LDS is associated with aneurysms or dissections of the aorta similar to Marfan syndrome (MFS) as well as arterial tortuosity and aneurysms in the peripheral arteries. The purpose of this study was to evaluate the arterial diseases of LDS to differentiate it from MFS. A total of 10 LDS patients with an identified mutation in TGFBR (6 male, 4 female; mean age 36.3 years) and 20 MFS patients with an identified mutation in fibrilin-1 who were age- and sex-matched to the LDS subjects (12 male, 8 female; mean age 37.1 years) were reviewed. The prevalence of vertebral arterial tortuosity (VAT) and peripheral aneurysm (PAN) was studied using computed tomography angiography. In all, 9 of the 10 LDS patients had VAT, and five PANs were observed in 3 patients. In contrast, 8 (40%) of the MFS patients had VAT, and 1 patient had a PAN. LDS had a higher prevalence of VAT (P=0.017) by Fisher's exact test. The VAT was highly prevalent among LDS patients. Thus, the presence of VAT has the potential to differentiate LDS from MFS.

    The human genome encodes a gene for an enzymatically active chitinase (CHIT1) located in a single copy on Chromosome 1, which is highly expressed by activated macrophages and in other cells of the innate immune response. Several dysfunctional mutations are known in CHIT1, including a 24-bp duplication in Exon 10 causing catalytic deficiency. This duplication is a common variant conserved in many human populations, except in West and South Africans. Thus it has been proposed that human migration out of Africa and the consequent reduction of exposure to chitin from environmental factors may have enabled the conservation of dysfunctional mutations in human chitinases. Our data obtained from 85 indigenous Amerindians from Peru, representative of populations characterized by high prevalence of chitin-bearing enteroparasites and intense entomophagy, reveal a very high frequency of the 24-bp duplication (47.06%), and of other single nucleotide polymorphisms which are known to partially affect enzymatic activity (G102S: 42.7% and A442G/V: 25.5%). Our finding is in line with a founder effect, but appears to confute our previous hypothesis of a protective role against parasite infection and sustains the discussion on the redundancy of chitinolytic function.

  17. Spherical equivalent refractive error in preschool children from a population with a high prevalence of astigmatism.

    Dobson, Velma; Harvey, Erin M; Miller, Joseph M

    2007-02-01

    To describe spherical equivalent (sph eq) refractive errors in preschool members of a Native American tribe with a high prevalence of astigmatism. Cycloplegic autorefraction measurements were obtained for 819 three- and four-year-old Tohono O'odham children, with follow-up measurements in 146 after 4 to 8 years. Mean sph eq was significantly more hyperopic in the astigmatic group than in the non-astigmatic group (1.24 vs. 0.87 D). At follow-up, prevalence of hyperopic sph eq and hyperopic astigmatism had significantly decreased, and prevalence of emmetropic/myopic sph eq and myopic astigmatism had significantly increased. The decrease in mean sph eq was similar in astigmats and non-astigmats. Astigmatism did not change over time. Most preschool children in this highly astigmatic population are hyperopic, with astigmats showing higher mean hyperopic sph eq than non-astigmats. Astigmats and non-astigmats show a similar decrease in amount of hyperopic sph eq over follow-up of 4 to 8 years.

    Full Text Available SUMMARY Little is known about the frequency of intestinal parasites in the elderly due to a lack of attention given to the occurrence of these infections among older adults. This study compares the frequency of Strongyloides stercoralis and other enteroparasites between elderly living in nursing homes (n = 100 and those noninstitutionalized (n = 100 from Uberlândia, state of Minas Gerais, southeastern Brazil, associated with data of epidemiological and socio-demographic conditions. Through coproparasitological examination of both groups, enteroparasites were detected in 15 of 200 individuals examined (7.5%; CI: 5.1- 9.9. S. stercoralis was the most frequent parasite 10/200 (5%; CI: 4.2-5.8, being significantly higher in males and in individuals with autonomy for daily living activities. There were no statistical differences in the prevalence of parasites between the two groups compared. In conclusion, S. stercoralis infection was highly prevalent in elderly patients and it does not depend on whether the individual was institutionalized or not.

    2013-01-01

    Full Text Available The aim of this study was to determine the prevalence of human papillomavirus (HPV in a women population living within the state of Amazonas, Brazil, and to determine the viral genotypes found. The study included 361 sexually active women over 18 years of age. We performed the Pap test and the molecular diagnosis for HPV DNA using polymerase chain reaction (PCR. The amplicons obtained were sequenced in automatic sequencer for genotyping. The presence of HPV DNA was found in 29.1% (105 of the women. Only 321 women presented satisfactory slides for cytological diagnosis, 97.9% (314 had normal cytology (negative for cancer, and 2.1% (7 had abnormal cytology (4 ASCUS, 1 LSIL, and 2 HSIL. The types more frequently found were HPV 16 (58.1% and HPV 58 (20.0%. Additionally, we found more 13 types of HPV. Compared with previous studies in Brazil, our data confirmed a high prevalence and genotypic diversity of HPV in Brazilian women.

  20. Proteomic analysis of highly prevalent amyloid A amyloidosis endemic to endangered island foxes.

    Patricia M Gaffney

    Full Text Available Amyloid A (AA amyloidosis is a debilitating, often fatal, systemic amyloid disease associated with chronic inflammation and persistently elevated serum amyloid A (SAA. Elevated SAA is necessary but not sufficient to cause disease and the risk factors for AA amyloidosis remain poorly understood. Here we identify an extraordinarily high prevalence of AA amyloidosis (34% in a genetically isolated population of island foxes (Urocyon littoralis with concurrent chronic inflammatory diseases. Amyloid deposits were most common in kidney (76%, spleen (58%, oral cavity (45%, and vasculature (44% and were composed of unbranching, 10 nm in diameter fibrils. Peptide sequencing by mass spectrometry revealed that SAA peptides were dominant in amyloid-laden kidney, together with high levels of apolipoprotein E, apolipoprotein A-IV, fibrinogen-α chain, and complement C3 and C4 (false discovery rate ≤ 0.05. Reassembled peptide sequences showed island fox SAA as an 111 amino acid protein, most similar to dog and artic fox, with 5 unique amino acid variants among carnivores. SAA peptides extended to the last two C-terminal amino acids in 5 of 9 samples, indicating that near full length SAA was often present in amyloid aggregates. These studies define a remarkably prevalent AA amyloidosis in island foxes with widespread systemic amyloid deposition, a unique SAA sequence, and the co-occurrence of AA with apolipoproteins.

    Candida dubliniensis is a recently described yeast species, closely related to Candida albicans. This work represents the first general survey of the carriage of C. dubliniensis in the oral cavities of HIV-positive patients in Argentina. We studied 133 strains isolated from 162 HIV-positive patients, using the following identification tests: chlamydospore production on corn meal agar with Tween 80; colony color on CHROMagar Candida media; differential growth at 45 degrees C on potato dextrose agar; D-xylose assimilation; chlamydospore formation on sunflower seed agar (SSA); carbohydrate assimilation profiles using the API 20 C Aux commercial kit and PCR using primers that hybridize to the class IV intron of the ACT1 gene. Out of the 133 strains, 21 were identified as C. dubliniensis, representing approximately 13% of the 162 patients in this study. From these data, we conclude that although the PCR assay is the most reliable method, clamydospore formation on SSA is an easier and less expensive test for the screening of C. dubliniensis in the routine laboratory. Our results show that C. dubliniensis has a high prevalence among HIV-positive patients in Argentina.

    2018-03-01

    Ichthyophonus occurred at high prevalence but low intensity in Pacific Halibut Hippoglossus stenolepis throughout the West Coast of North America, ranging from coastal Oregon to the Bering Sea. Infection prevalence in adults was variable on spatial and temporal scales, with the lowest prevalence typically occurring on the edges of the geographic range and highest prevalence consistently occurring inside Prince William Sound, Alaska (58-77%). Additionally, intra-annual differences occurred at Albatross-Portlock, Alaska (71% versus 32% within 2012), and interannual differences occurred along coastal Oregon (50% in 2012 versus 12% in 2015). The infection prevalence was influenced by host age, increasing from 3% or less among the youngest cohorts (age ≤ 6) to 39-54% among age-9-17 cohorts, then decreasing to 27% among the oldest (age-18+) cohorts. There was little indication of significant disease impacts to Pacific Halibut, as the intensity of infection was uniformly low and length at age was similar between infected and uninfected cohorts. These results suggest that Ichthyophonus in Pacific Halibut currently represents a stable parasite-host paradigm in the North Pacific. © 2018 American Fisheries Society.

    2014-12-01

    Full Text Available Background: Men who have sex with men (MSM are disproportionately affected by sexually transmitted infection. The aim of this cross-sectional study is to prospectively detect the prevalence of chlamydia trachomatis (CT, neisseria gonorrhoeae (NG, mycoplasma genitalium (MG, and high risk human papillomavirus (HR-HPV, and syphilis in a population of asymptomatic sexually active MSM. Methods: Rectal, pharyngeal, and urine samples for CT, NG, MG, and HR-HPV were analyzed in 116 MSM patients attending the clinic for their routine follow-up during the period the study was conducted: 99 patients were issued from the clinic routine follow-up for their HIV infection, and 17 attended the clinic because they were sexual partners of an HIV infected male. Results: An STI was found in 16% of the patients (19/116, with at least one bacterial strain (CT, NG, or MG found in one site (the pharynx, rectum, or urine. Conclusions: In this study, 16% of the MSM reporting recent RAI were asymptomatic carriers of rectal CT, NG, or MG. According to the high prevalence of asymptomatic STIs found in our MSM population and in other studies, prevention efforts in the form of counseling about the risk of STI need to be done in the population of MSM.

    It is fairly easy to detect advanced valve lesions of established rheumatic heart disease by echocardiography in the clinically identified cases of rheumatic heart disease. However, to diagnose a subclinical case of rheumatic heart disease, no uniform set of echocardiographic criteria exist. Moderate thickening of valve leaflets is considered an indicator of established rheumatic heart disease. World Health Organization criteria for diagnosing probable rheumatic heart disease are more sensitive and are based on the detection of significant regurgitation of mitral and/or aortic valves by color Doppler. We attempted diagnosing RHD in school children in Bikaner city by cardiac ultrasound. The stratified cluster sampling technique was employed to identify 31 random clusters in the coeducational schools of Bikaner city. We selected 1059 school children aged 6-15 years from these schools. An experienced operator did careful cardiac auscultation and echocardiographic study. A second expert confirmed the echocardiographic findings. The prevalence of lesions suggestive of rheumatic heart disease by echocardiography was 51 per 1,000 (denominator = 1059; 95% CI: 38-64 per 1,000). We were able to clinically diagnose RHD in one child. None of these children or their parents having echocardiographic evidence of RHD could provide a positive history of acute rheumatic fever. By echocardiographic screening, we found a high prevalence of rheumatic heart disease in the surveyed population. Clinical auscultation had much lower diagnostic efficacy.

    To identify areas of risk for canine-related zoonoses in Serbia, the aim of this study was to provide baseline knowledge about intestinal parasites in 151 dogs (65 household pets, 75 stray and 11 military working dogs) from Belgrade. The following parasites, with their respective prevalences, were detected: Giardia duodenalis (14.6%), Ancylostomatidae (24.5%), Toxocara canis (30.5%), Trichuris vulpis (47.0%) and Taenia-type helminths (6.6%). Of all examined dogs, 75.5% (114/151) were found to harbour at least one parasite species. Of these, mixed infections with up to four species per dog occurred in 44.7% (51/114). Infections with all detected species were significantly higher (p dogs (93.3%) versus household pets (50.8%). Among all parasites, agents with zoonotic potential including Giardia, Ancylostomatidae and Toxocara were detected in 58.3% (88/151) of all examined dogs with a significant difference (p dogs, stray dogs and household pets, respectively). The high prevalence of zoonotic parasites registered in the dog population from a highly urban area in south-eastern Europe indicates a potential risk to human health. Thus, veterinarians should play an important role in helping to prevent or minimise zoonotic transmission.

    Canine babesiosis is an important vector-borne hemoparasitic disease caused by Babesia canis vogeli and Babesia gibsoni , in India. The communication places on record the salient findings of the study directed to detect and characterize the pathogenic B. gibsoni isolates of Kerala state. A total of 150 dogs were examined for the presence of hemoparasites by light microscopy as well as by PCR targeting the 18S rRNA gene of B. gibsoni . Hematological parameters were also analysed. Phylogenetic tree was constructed based on Tamura kei model adopting ML method. A sensitive and specific polymerase chain reaction assay was developed with newly designed primer pair BAGI-F/BAGI-R for the amplification of 488 bp fragment of 18S rRNA gene of B. gibsoni . Out of the 150 dogs examined, molecular evidence of B. gibsoni was recorded in 47.3% animals, while light microscopy detected the infection in 26.67% cases. The phylogenetic analyses revealed that B. gibsoni , Kerala, isolate was closest and occurred together with Bareilly isolate. Anemia and thrombocytopenia were the significant hematological alterations in chronic B. gibsoni infection. A high prevalence of natural infection of B. gibsoni was detected among the study population. The affected animals showed anaemia and thrombocytopenia. Phylogenetic analysis of this pathogenic isolate from south India revealed the closest similarity with Bareilly isolates.

  9. Unexpected finding of a high prevalence of perinatal hypertension in a rural Haitian village: An observational study

    Bryce C Gagliano

    2016-01-01

    Full Text Available Background Hypertensive disorders in pregnancy are associated with maternal mortality worldwide. In Haiti, the risk of perinatal maternal death is high with sparse data concerning the prevalence of gestational hypertension (HTN reported from remote regions. Maternal morbidity associated with HTN-related sequellae will place a strain on the family unit. Thus, it is vital to the health of mothers as well as the rural communities to gain a better understanding of HTN with the goal of decreasing perinatal morbidity and mortality in areas without access to advanced healthcare. Methods In this study, we measured the prevalence of HTN in perinatal women in the Thomazeau region of Haiti who presented to a regional clinic staffed by volunteer international providers. Retrospective pre- and postpartum data was analyzed from 436 women who presented between January 2013 and July 2015. Additionally, a subset of current (June-July 2015 prepartum (n=200 and postpartum (n=82 women had a urinalysis performed to access for proteinuria and other urine markers. Demographic data collected included blood pressure, age, weight, height, gravidity, and parity. The criteria for HTN was defined as two blood pressure readings taken at separate time points with systolic and diastolic pressures greater than 140 and 90 mmHg, respectively. Results In this cohort of 436 women, 57 (13.1% met the criteria of HTN before giving birth and 98 (22.5% afterwards. Of the women found to be hypertensive, 64 (65.3% of the hypertensive women after birth had not been hypertensive prepartum. Within the two-week current period assessing 282 women, 3 (1.5% prepartum and 13 (15.9% postpartum women with HTN had trace proteinuria. Conclusions In this cohort of rural women, we describe an unusually high prevalence of new onset postpartum HTN. As complications of gestational HTN including preeclampsia and eclampsia may contribute to perinatal morbidity and mortality for both mother and baby in

  10. Design basis knowledge management for the newcomer countries. Relying on the owner/operator as a knowledgeable customer

    Lepouze, Benoît

    2013-01-01

    Becoming a knowledgeable customer is the first step to manage knowledge: • Vendors, consulting firms, TSOs can assist the future operator but it will remain the sole owner of the decisions; • Future owner operator has to become a knowledgeable customer: • Know what to ask for, • Know how to ask for it, • Know how to check if it got what it asked. • Where should knowledge management belong (management?, HRD?, procurement?) and is it important? What it means for DBKM ? (example): • The owner/operator (the licensee) is responsible in front of the safety agency: it should answer its questions at every stage of the program; • It will often turn back to its vendor/suppliers especially for detailed design questions; • But that means it has to know what to ask for and to check the result before talking to the regulator; • That also means it has to make sure knowledge is managed throughout the life of the program

  11. High prevalence but limited evidence in complementary and alternative medicine: guidelines for future research

    2014-01-01

    The use of complementary and alternative Medicine (CAM) has increased over the past two decades in Europe. Nonetheless, research investigating the evidence to support its use remains limited. The CAMbrella project funded by the European Commission aimed to develop a strategic research agenda starting by systematically evaluating the state of CAM in the EU. CAMbrella involved 9 work packages covering issues such as the definition of CAM; its legal status, provision and use in the EU; and a synthesis of international research perspectives. Based on the work package reports, we developed a strategic and methodologically robust research roadmap based on expert workshops, a systematic Delphi-based process and a final consensus conference. The CAMbrella project suggests six core areas for research to examine the potential contribution of CAM to the health care challenges faced by the EU. These areas include evaluating the prevalence of CAM use in Europe; the EU cititzens’ needs and attitudes regarding CAM; the safety of CAM; the comparative effectiveness of CAM; the effects of meaning and context on CAM outcomes; and different models for integrating CAM into existing health care systems. CAM research should use methods generally accepted in the evaluation of health services, including comparative effectiveness studies and mixed-methods designs. A research strategy is urgently needed, ideally led by a European CAM coordinating research office dedicated to fostering systematic communication between EU governments, the public, charitable and industry funders, researchers and other stakeholders. A European Centre for CAM should also be established to monitor and further a coordinated research strategy with sufficient funds to commission and promote high quality, independent research focusing on the public’s health needs and pan-European collaboration. There is a disparity between highly prevalent use of CAM in Europe and solid knowledge about it. A strategic approach on

    Hypogonadism may complicate Addison's disease (primary hypoadrenalism), but prevalence and metabolic sequelae of hypogonadism in Addison's disease are poorly described. We recruited patients from the South African Addison's disease national registry who received stable replacement doses of hydrocortisone and had no acute illness. Male biochemical testosterone deficiency was defined as an early morning basal testosterone10 or 12 IU/l). Testosterone deficiency did not correlate with age, disease duration or hydrocortisone dose. Untreated male hypogonadal subjects had a higher (mean ± standard deviation) BMI compared to eugonadal subjects 29.2 ± 4.9 kg/m(2) vs. 24.7 ± 3.4 kg/m(2) (p=0.01) and a higher median (interquartile range) high-sensitive-CRP 6.4 (2.5-14.0) mg/l vs. 1.45 (0.6-2.8) mg/l (p=0.002). There were no differences between the 2 groups in lipids, lipoproteins and fasting glucose. The median (interquartile range) DHEAS was lower in the hypogonadal 0.31 (0.27-0.37) μmol/l, compared with the eugonadal group 0.75 (0.50-1.51) μmol/l (p=0.005). POF was documented in 11% of female patients. Male testosterone deficiency was highly prevalent in this cohort and was primarily due to secondary hypogonadism.

Male and female hypogonadism appears to be a common complication of Addison's disease and may contribute to its morbidity. © Georg Thieme Verlag KG Stuttgart · New York.

  13. High prevalence of respiratory muscle weakness in hospitalized acute heart failure elderly patients.

    Pedro Verissimo

    Full Text Available Respiratory Muscle Weakness (RMW has been defined when the maximum inspiratory pressure (MIP is lower than 70% of the predictive value. The prevalence of RMW in chronic heart failure patients is 30 to 50%. So far there are no studies on the prevalence of RMW in acute heart failure (AHF patients.Evaluate the prevalence of RMW in patients admitted because of AHF and the condition of respiratory muscle strength on discharge from the hospital.Sixty-three patients had their MIP measured on two occasions: at the beginning of the hospital stay, after they had reached respiratory, hemodynamic and clinical stability and before discharge from the hospital. The apparatus and technique to measure MIP were adapted because of age-related limitations of the patients. Data on cardiac ejection fraction, ECG, brain natriuretic peptide (BNP levels and on the use of noninvasive ventilation (NIV were collected.The mean age of the 63 patients under study was 75 years. On admission the mean ejection fraction was 33% (95% CI: 31-35 and the BNP hormone median value was 726.5 pg/ml (range: 217 to 2283 pg/ml; 65% of the patients used NIV. The median value of MIP measured after clinical stabilization was -52.7 cmH2O (range: -20 to -120 cmH2O; 76% of the patients had MIP values below 70% of the predictive value. On discharge, after a median hospital stay of 11 days, the median MIP was -53.5 cmH2O (range:-20 to -150 cmH2O; 71% of the patients maintained their MIP values below 70% of the predictive value. The differences found were not statistically significant.Elderly patients admitted with AHF may present a high prevalence of RMW on admission; this condition may be maintained at similar levels on discharge in a large percentage of these patients, even after clinical stabilization of the heart condition.

    Samples collected in 2008 and 2009, from 49 turkey flocks of 6 to 43 days in age and presenting clinical signs of enteric disease and high mortality, were tested by polymerase chain reaction and reverse transcription-polymerase chain reaction for the presence of viruses currently associated with enteric disease (ED) syndromes: astrovirus, reovirus, rotavirus, coronavirus, adenovirus, and parvovirus. Turkey astroviruses were found in 83.67% of the cases and turkey astrovirus 2 (TAst-2) in 26.53%. The investigations directly demonstrated the high prevalence of turkey parvovirus (TuPV) in 23 flocks (46.9%) experiencing signs of ED, making this pathogen the second most identified after astroviruses. Phylogenetic analysis on a 527 base pair-long region from the NS1 gene revealed two main clusters, a chicken parvovirus (ChPV) and a TuPV group, but also the presence of a divergent branch of tentatively named "TuPV-like ChPV" strains. The 23 Hungarian TuPV strains were separately positioned in two groups from the American origin sequences in the TuPV cluster. An Avail-based restriction fragment length polymorphism assay has also been developed for the quick differentiation of TuPV, ChPV, and divergent TuPV-like ChPV strains. As most detected enteric viruses have been directly demonstrated in healthy turkey flocks as well, the epidemiology of this disease complex remains unclear, suggesting that a certain combination of pathogens, environmental factors, or both are necessary for the development of clinical signs.

    Sporothrix schenckii, previously assumed to be the sole agent of human and animal sporotrichosis, is in fact a species complex. Recently recognized taxa include S. brasiliensis, S. globosa, S. mexicana, and S. luriei, in addition to S. schenckii sensu stricto. Over the last decades, large epidemics of sporotrichosis occurred in Brazil due to zoonotic transmission, and cats were pointed out as key susceptible hosts. In order to understand the eco-epidemiology of feline sporotrichosis and its role in human sporotrichosis a survey was conducted among symptomatic cats. Prevalence and phylogenetic relationships among feline Sporothrix species were investigated by reconstructing their phylogenetic origin using the calmodulin (CAL) and the translation elongation factor-1 alpha (EF1α) loci in strains originated from Rio de Janeiro (RJ, n = 15), Rio Grande do Sul (RS, n = 10), Paraná (PR, n = 4), São Paulo (SP, n =3) and Minas Gerais (MG, n = 1). Our results showed that S. brasiliensis is highly prevalent among cats (96.9%) with sporotrichosis, while S. schenckii was identified only once. The genotype of Sporothrix from cats was found identical to S. brasiliensis from human sources confirming that the disease is transmitted by cats. Sporothrix brasiliensis presented low genetic diversity compared to its sister taxon S. schenckii. No evidence of recombination in S. brasiliensis was found by split decomposition or PHI-test analysis, suggesting that S. brasiliensis is a clonal species. Strains recovered in states SP, MG and PR share the genotype of the RJ outbreak, different from the RS clone. The occurrence of separate genotypes among strains indicated that the Brazilian S. brasiliensis epidemic has at least two distinct sources. We suggest that cats represent a major host and the main source of cat and human S. brasiliensis infections in Brazil.

    Bronchiectasis is one of the common chronic respiratory diseases and associated with respiratory morbidity and mortality. However, neither its prevalence nor its etiology is well-defined. We aimed to estimate the prevalence and risk factors of bronchiectasis in adults. In a retrospective study, we analyzed radiologic findings on chest computed tomography (CT) images performed as part of a health-screening program. From January to December 2008, 1,409 (24.6%) of 5,727 participants in the screening program of a health promotion center at a university hospital underwent chest CT scans based on the subject's decision. Bronchiectasis was diagnosed, if there was abnormal bronchial dilatation in any area of both lungs on chest CT. Respiratory symptoms, smoking status, and past medical history were also analyzed to define clinical characteristics and risk factors of bronchiectasis. Of 1,409 patients (aged 23-86 years), who were screened for respiratory diseases using chest CT for one year in a health promotion center, 129 patients (9.1%) were diagnosed with bronchiectasis. The prevalence of bronchiectasis was higher in females than in males (11.5% vs. 7.9%, p=0.022) and increased with age. Respiratory symptoms were reported in 53.7% of subjects. Previous history of tuberculosis (TB) (odds ratio (OR) 4.61, 95% confidence interval (Cl) 2.39-8.88, p=0.001) and age (OR 2.49, 95% Cl 1.56-3.98, p=0.001) were significantly associated with bronchiectasis. This retrospective analysis of chest CT findings in health screening examinees revealed a very high prevalence of bronchiectasis in adults. Previous TB infection is one of the major causes of bronchiectasis. (author)

    Our study aimed to determine the prevalence of occult left-heart disease in patients with scleroderma and pulmonary hypertension. In patients with pulmonary hypertension (mean pulmonary artery pressure (mean PAP)≥25 mmHg), differentiation between pre- and post-capillary pulmonary hypertension has been made according to pulmonary artery wedge pressure (PAWP) less than or more than 15 mmHg, respectively. We performed a retrospective chart review of 107 scleroderma patients. All patients with suspected pulmonary hypertension had routine right or left heart catheterisation with left ventricular end-diastolic pressure (LVEDP) measurement pre-/post-fluid challenge. We extracted demographic, haemodynamic and echocardiographic data. Patients were classified into one of four groups: haemodynamically normal (mean PAP15 mmHg); occult PVH (mean PAP≥25 mmHg, PAWP≤15 mmHg, LVEDP>15 mmHg before or after fluid challenge); and pulmonary arterial hypertension (PAH) (mean PAP≥25 mmHg, PAWP≤15 mmHg and LVEDP≤15 mmHg before or after fluid challenge). 53 out of 107 patients had pulmonary hypertension. Based on the PAWP-based definition, 29 out of 53 had PAH and 24 out of 53 had PVH. After considering the resting and post-fluid-challenge LVEDP, 11 PAH patients were reclassified as occult PVH. The occult PVH group was haemodynamically, echocardiographically and demographically closer to the PVH group than the PAH group. PVH had high prevalence in our scleroderma-pulmonary hypertension population. Distinguishing PAH from PVH with only PAWP may result in some PVH patients being misclassified as having PAH.

    2017-07-01

    Beak and feather disease virus (BFDV) is a circovirus and the cause of psittacine beak and feather disease (PBFD). This disease is characterized by feather and beak deformities and is a recognized threat to endangered Psittaciformes (parrots and cockatoos). The role that non-psittacine birds may play as reservoirs of infection is unclear. This study aimed to begin addressing this gap in our knowledge of PBFD. Liver samples were collected from birds presented to the Australian Wildlife Health Centre at Zoos Victoria's Healesville Sanctuary for veterinary care between December 2014 and December 2015, and tested for BFDV DNA using polymerase chain reaction coupled with sequencing and phylogenetic analyses.Results/Key findings. Overall BFDV was detected in 38.1 % of 210 birds. BFDV was detected at high prevalence (56.2 %) in psittacine birds, in the majority of cases without any observed clinical signs of PBFD. We also found that BFDV was more common in non-psittacine species than previously recognized, with BFDV detected at 20.0 % prevalence in the non-psittacine birds tested, including species with no clear ecological association with psittacines, and without showing any detectable clinical signs of BFDV infection. Further research to determine the infectivity and transmissibility of BFDV in non-psittacine species is indicated. Until such work is undertaken the findings from this study suggest that every bird should be considered a potential carrier of BFDV, regardless of species and clinical presentation. Veterinary clinics and wildlife rehabilitation facilities caring for birds that are susceptible to PBFD should reconsider biosecurity protocols aimed at controlling BFDV.

    QT-interval prolongation of unknown aetiology is common in Turner syndrome. This study set out to explore the presence of known long QT mutations in Turner syndrome and to examine the corrected QT-interval (QTc) over time and relate the findings to the Turner syndrome phenotype. Adult women with Turner syndrome (n = 88) were examined thrice and 68 age-matched healthy controls were examined once. QTc was measured by one blinded reader (intra-reader variability: 0.7%), and adjusted for influence of heart rate by Bazett's (bQTc) and Hodges's formula (hQTc). The prevalence of mutations in genes related to Long QT syndrome was determined in women with Turner syndrome and a QTc >432.0 milliseconds (ms). Echocardiographic assessment of aortic valve morphology, 24-hour blood pressures and blood samples were done. The mean hQTc in women with Turner syndrome (414.0 ± 25.5 ms) compared to controls (390.4 ± 17.8 ms) was prolonged (pTurner syndrome karyotypes (418.2 ± 24.8 vs. 407.6 ± 25.5 ms; p = 0.055). In women with Turner syndrome and a bQTc >432 ms, 7 had mutations in major Long QT syndrome genes (SCN5A and KCNH2) and one in a minor Long QT syndrome gene (KCNE2). There is a high prevalence of mutations in the major LQTS genes in women with TS and prolonged QTc. It remains to be settled, whether these findings are related to the unexplained excess mortality in Turner women.

    Oxidative stress has been linked to many obesity-related conditions among children including cardiovascular disease, diabetes mellitus and hypertension. Exposure to environmental chemicals such as phthalates, ubiquitously found in humans, may also generate reactive oxygen species and subsequent oxidative stress. We examined longitudinal changes of 8-isoprostane urinary concentrations, a validated biomarker of oxidative stress, and associations with maternal prenatal urinary concentrations of phthalate metabolites for 258 children at 5, 9 and 14 years of age participating in a birth cohort residing in an agricultural area in California. Phthalates are endocrine disruptors, and in utero exposure has been also linked to altered lipid metabolism, as well as adverse birth and neurodevelopmental outcomes. We found that median creatinine-corrected 8-isoprostane concentrations remained constant across all age groups and did not differ by sex. Total cholesterol, systolic and diastolic blood pressure were positively associated with 8-isoprostane in 14-year-old children. No associations were observed between 8-isoprostane and body mass index (BMI), BMI Z-score or waist circumference at any age. Concentrations of three metabolites of high molecular weight phthalates measured at 13 weeks of gestation (monobenzyl, monocarboxyoctyl and monocarboxynonyl phthalates) were negatively associated with 8-isoprostane concentrations among 9-year olds. However, at 14 years of age, isoprostane concentrations were positively associated with two other metabolites (mono(2-ethylhexyl) and mono(2-ethyl-5-carboxypentyl) phthalates) measured in early pregnancy. Longitudinal data on 8-isoprostane in this pediatric population with a high prevalence of obesity provides new insight on certain potential cardiometabolic risks of prenatal exposure to phthalates.

    In patients with cancer, weight loss can be related to simple starvation, disturbed metabolism, or both. In patients with head and neck cancer (HNC), weight loss often is attributed to simple starvation because the obvious oral symptoms are known to hinder dietary intake. In this population, cachexia remains a relatively unexplored phenomenon. The aim of this study was to explore the prevalence of cachexia and precachexia in patients with newly diagnosed HNC. Fifty-nine patients with newly diagnosed HNC were asked to participate in the prospective cohort study, from which only baseline data were used in the analyses. Measurements were performed 1 wk before cancer treatment, that is, cachexia status by Fearon's cancer-specific framework, dietary intake, muscle mass, muscle strength, and biochemical markers (C-reactive protein, albumin, hemoglobin, interleukin-1β, interleukin-6, and tumor necrosis factor-α) were assessed. Data of 26 patients were included in the analyses (59% participation rate). Forty-two percent of the patients (n = 12) were classified as cachectic and 15% (n = 4) as precachectic. Muscle mass depletion was significantly more frequent in cachectic patients (67%) than in noncachectic patients (14%; P = 0.014). No differences in inflammatory markers were observed between cachectic and noncachectic patients. This exploratory study suggested a high prevalence of cachexia (42%) in patients with newly diagnosed HNC. Although a large study is needed to further elucidate the role of cachexia in patients with HNC, the data presented here suggest that cachexia is a common problem in this patient population, which has therapeutic and prognostic implications.

    Previous studies assessing vitamin D status in adolescents with eating disorders showed inconsistent results. The aim of the current study was to assess vitamin D status in a large cohort of adolescent inpatients with eating disorders and its relation to bone mineral density (BMD) and depression. 25-Hydroxyvitamin D (25OHD), calcium, phosphorus, and alkaline phosphatase levels as well as BMD and depression were assessed on admission in 87 inpatients (aged 16 ± 2 years, females = 81) with eating disorders [anorexia nervosa (AN) = 64; bulimia nervosa (BN) = 5; eating disorders not otherwise specified-binge/purge type (EDNOS-B/P) = 18]. Mean 25OHD levels were 24.1 ± 7.5 ng/ml (25.0 ± 7.6, 25.4 ± 9.9, and 22.0 ± 9.9 ng/ml in patients with AB, BN, and EDNOS-B/P, respectively). Vitamin D deficiency (32 ng/ml, considered optimal by some experts. No associations were found between 25OHD levels and BMD or comorbid depression. 25OHD levels during winter were significantly lower than summer levels (p EDNOS-B/P type was low (-1.5 ± 1.1) and correlated with body mass index standard deviation score (p = .03). Adolescents with eating disorders show a high prevalence of vitamin D deficiency and insufficiency. Given the risk of osteoporosis in this population, 25OHD levels found in this group may not offer optimal bone protection. Vitamin D levels should be routinely checked and supplementation should be administered as required. © 2014 Wiley Periodicals, Inc.

    Tropheryma whipplei is the causative agent of Whipple disease. T. whipplei has also been detected in asymptomatic carriers with a very different prevalence. To date, in Spain, there are no data regarding the prevalence of T. whipplei in a healthy population or in HIV-positive patients, or in chronic fatigue syndrome (CFS). Therefore, the aim of this work was to assess the prevalence of T. whipplei in stools in those populations. Stools from 21 HIV-negative subjects, 65 HIV-infected, and 12 CFS patients were analysed using real time-PCR. HIV-negative and positive subjects were divided into two groups, depending on the presence/absence of metabolic syndrome (MS). Positive samples were sequenced. The prevalence of T. whipplei was 25.51% in 98 stool samples analysed. Prevalence in HIV-positive patients was significantly higher than in HIV-negative (33.8% vs. 9.09%, p=0.008). Prevalence in the control group with no associated diseases was 20%, whereas no positive samples were observed in HIV-negative patients with MS, or in those diagnosed with CFS. The prevalence observed in HIV-positive patients without MS was 30.35%, and with MS it was 55.5%. The number of positive samples varies depending on the primers used, although no statistically significant differences were observed. There is a high prevalence of asymptomatic carriers of T. whipplei among healthy and in HIV-infected people from Spain. The role of T. whipplei in HIV patients with MS is unclear, but the prevalence is higher than in other populations.

  5. Alcoholic Liver Disease in the Asian–Pacific Region with High Prevalence of Chronic Viral Hepatitis

    Sien-Sing Yang

    2016-09-01

    Full Text Available The hospitalized cases and mortality from alcoholic liver disease (ALD are increasing in Taiwan and worldwide. Meanwhile, the Asia–Pacific region also has a high prevalence of hepatitis B virus (HBV and hepatocellular carcinoma (HCC. The Taiwanese have the highest percentage of aldehyde dehydrogenase 2 (ALDH2 deficiency and the lowest amount of alcohol consumption. Based on the histological changes, ALD is clinically classified as steatosis, alcoholic hepatitis, alcoholic fibrosis, alcoholic cirrhosis, and alcoholic hepatitis on cirrhosis. Patients with overt alcoholic hepatitis often develop marked hepatomegaly, audible hepatic arterial bruit, mild leukocytosis, and mild fever. Patients having alcoholic cirrhosis had much more serious complications and mortality. It is clinically important to identify hepatic fibrosis and cirrhosis earlier for early management. Active assessments for esophageal varices and ascites may help the diagnosis of cirrhosis. Sonography is helpful for exanimating features of cirrhosis including portal hypertension, ascites, increased hepatic portal flow, and collaterals. Synergistic damage of viral hepatitis on ALD patients lead to rapid progression to cirrhosis and HCC. Distinct from the Western population, 30% of Taiwanese alcoholics had concomitant chronic HBV regardless of the different histologic categories. Patient groups with combined alcoholics and HBV had fewer platelet counts and much more cirrhosis with Ishak Stage 5–6 fibrosis. The annual incidences of HCC were significantly higher in alcoholic cirrhotic patients having concomitant HBV infection than those with only HBV infection or alcoholism alone. Antiviral nucleotide and nucleoside analogs therapy reduces the prevalence of HCC to a similar level to those ALD patients without active HBV.

    Full Text Available Abstract Background There are few data on the prevalence of schistosomiasis in Darfur. We conducted this study in response to reports of 15 laboratory confirmed cases of schistosomiasis and visible haematuria among children from two communities in South Darfur. The aim of the study was to estimate the prevalence of schistosomiasis in the area and to decide on modalities of intervention. Methods A cross-sectional survey involving 811 children and adults from schools and health facilities was conducted in two communities of South Darfur in March 2010. Urine samples were collected and examined for ova of Schistosoma haematobium using a sedimentation technique. A semi-structured format was used to collect socio-demographic characteristics of the participants. Results Eight hundred eleven (811 urine samples were collected, 415 from Alsafia and 396 from Abuselala. Of the collected samples in 56.0% (95% Confidence Interval (CI; 52.6-59.4 Schistosoma eggs were found. The prevalence was high in both Abuselala 73.3% (95% CI; 68.9-77.6 and Alsafia 39.5% (95% CI; 34.8-44.2. More males (61.7%, 95%CI; 56.5-64.9 were infected than females (52.1%, 95%CI; 48.2-56.0. Children in the age group 10-14 has the highest (73.0%, 95%CI; 68.7-77.2 infection rate. School age children (6-15 years are more likely to be infected than those >15 years (Adjusted Odds Ratio (AOR = 2.70, 95% CI; 1.80-4.06. Individuals in Abuselala are more likely to be infected than those who live in Alsafia (AOR = 4.3, 95% CI; 3.2-5.9. Conclusion The findings of this study indicate that S. hematobium is endemic in Alsafia and Abuselala South Darfur in Sudan with a high prevalence of infection among older children. This signifies the importance of urgent intervention through Mass Drug Administration (MDA to halt the infection cycle and tailored health messages to targeted groups. Based on the findings MDA was conducted in the villages.

School age children (6-15 years) are more likely to be infected than those >15 years (Adjusted Odds Ratio (AOR) = 2.70, 95% CI; 1.80-4.06). Individuals in Abuselala are more likely to be infected than those who live in Alsafia (AOR = 4.3, 95% CI; 3.2-5.9). The findings of this study indicate that S. hematobium is endemic in Alsafia and Abuselala South Darfur in Sudan with a high prevalence of infection among older children. This signifies the importance of urgent intervention through Mass Drug Administration (MDA) to halt the infection cycle and tailored health messages to targeted groups. Based on the findings MDA was conducted in the villages.

    Human papillomaviruses (HPV) are causally associated with ano-genital and a subset of head and neck cancers. Rising incidence of HPV+ anal cancers and head and neck cancers have now been demonstrated in the developed world over the last decade. The majority of published data on HPV prevalence at the anal and oro-pharyngeal sites are from studies of higher-risk populations. There is a paucity of data on the prevalence of HPV at non-cervical sites in lower risk, non-HIV+ women and this study was designed to provide initial pilot data on a population of women recalled for colposcopy as part of the UK cervical screening programme. 100 non-HIV+ women with abnormal cervical cytology, attending clinic for colposcopic examination were recruited. Swabs from the oro-pharyngeal, anal and cervical sites were taken and DNA extracted. HPV detection and genotyping were performed using a standardised, commercially available PCR-line blot assay, which is used to genotype 37 HPV subtypes known to infect the ano-genital and oro-pharyngeal areas. Strict sampling and laboratory precautions were taken to prevent cross-contamination. There was a very high prevalence of HPV infection at all three sites: 96.0%, 91.4% and 92.4% at the cervix, anus and oro-pharynx, respectively. Multiple HPV subtype infections were dominant at all 3 mucosal sites. At least one or more HR genotype was present at both the cervix/anus in 39/52 (75.0%) patients; both the cervix/oro-pharynx in 48/56 (85.7%) patients; and both the anus/oro-pharynx in 39/52 (75.0%) patients. HPV 16 infection was highly dominant across all mucosal sites, with over a 2-fold increase over the next most prevalent subtype (HPV 31). Women with abnormal smears have widespread infection with high-risk HPV at the cervical, anal and oro-pharyngeal mucosal sites and may represent a higher risk population for HPV disease in the future

    Background Legionella is the causative agent of Legionnaires' disease, and hot springs are a major source of outbreaks of this disease. It is important from a public health perspective to survey hot spring environments for the presence of Legionella. Methods Prospective surveillance of the extent of Legionella pollution was conducted at three hot spring recreational areas in Beijing, China in 2011. Pulsed-field gel electrophoresis (PFGE) and sequence-based typing (SBT) were used to describe the genetic polymorphism of isolates. The intracellular growth ability of the isolates was determined by interacting with J774 cells and plating the dilutions onto BCYE agar plates. Results Overall, 51.9% of spring water samples showed Legionella-positive, and their concentrations ranged from 1 CFU/liter to 2,218 CFU/liter. The positive rates of Legionella were significantly associated with a free chlorine concentration of ≥0.2 mg/L, urea concentration of ≥0.05 mg/L, total microbial counts of ≥400 CFU/ml and total coliform of ≥3 MPN/L (pLegionella concentrations were significantly associated with sample temperature, pH, total microbial counts and total coliform (pLegionella pneumophila was the most frequently isolated species (98.9%), and the isolated serogroups included serogroups 3 (25.3%), 6 (23.4%), 5 (19.2%), 1 (18.5%), 2 (10.2%), 8 (0.4%), 10 (0.8%), 9 (1.9%) and 12 (0.4%). Two hundred and twenty-eight isolates were analyzed by PFGE and 62 different patterns were obtained. Fifty-seven L. pneumophila isolates were selected for SBT analysis and divided into 35 different sequence types with 5 main clonal groups. All the 57 isolates had high intracellular growth ability. Conclusions Our results demonstrated high prevalence and genetic polymorphism of Legionella in springs in Beijing, China, and the SBT and intracellular growth assay results suggested that the Legionella isolates of hot spring environments were pathogenic.

  14. High prevalence of hepatitis C infection in a Brazilian prison: identification of risk factors for infection

    Thaís Guimarães

    Full Text Available Hepatitis C virus (HCV causes infectious hepatitis worldwide. It is transmitted mainly by blood products and sharing of intravenous paraphernalia during illicit drug use. High prevalence rates have been described among specific groups considered to be at higher risk for HCV infection, including prison inmates. The objectives of this study were: to determine the HCV seroprevalence among inmates of Casa de Detenção de São Paulo; to identify risk factors for HCV infection; and to compare the seroprevalence of HCV to other blood borne or sexually transmitted diseases. From December, 1993, to January, 1994, a total of 779 inmates were interviewed to collect information on sociodemographic status, sexual behavior, and past experience with illicit drugs. Blood samples were obtained from 756 inmates for serological tests. 310 (41% blood samples were positive for anti-HCV, 425 (56.2% were negative, and 21 (2.8% showed indeterminate results. In this population, we found a seroprevalence of 13.7% for HIV, 3.3% for syphilis (VDRL, and 68.1% for hepatitis B virus previous infection. Four variables were each identified as associated with a positive anti-HCV serologic test: a positive VDRL (OR = 2.63 IC 95% 1.08 to 6.36; a time of current imprisonment longer than 130 months (OR = 2.44 IC 95% 1.04 to 5.71; previous incarceration at Casa de Detenção de São Paulo (OR = 1.73 IC 95% 1.19 to 2.52 and; illicit drug use before admission to the Casa de Detenção de São Paulo (OR = 1.64 IC 95% 1.15 to 2.33. The seroprevalence of HCV antibodies among the study population was high (41%, indeed, one of the highest clusters of HCV infection recorded until now. Four variables were each shown to be associated with HCV infection. The simultaneous presence of these 4 variables is associated with an 82% probability of being anti-HCV positive. Although risk factor analysis indicates most HCV infections occur prior to inprisonment, initiation of control measures to prevent

    There are few data in Argentina on the prevalence and management of bone and mineral metabolism (BMM) in patients with chronic kidney disease (CKD). A survey was carried out in dialysis units in 2010 to measure the prevalence of and types of treatments for BMM disorders in Argentina. The data obtained was then compared to the published results from other large population studies. We recorded characteristics of dialysis centres and participating patients, the frequency of measurements and individual results for BMM biochemical markers, as well as the type of management used to control hyperphosphataemia and secondary hyperparathyroidism. 1210 patients from 25 dialysis centres in Argentina participated in the study (representing 4.7% of the country’s prevalent dialysis population in 2010). The mean patient age was 55.3±17.6 years, 60.8% were male, 3.3% were on peritoneal dialysis and 29.1% suffered diabetes. In all centres, phosphataemia and calcaemia were measured on a monthly basis, 60% of centres measured intact parathyroid hormone (iPTH) every 6 months, 36% every 3 to 4 months, and 4% annually. As recommended by K/DOQI, 51.6% of patients had adequate levels of calcium (8.4-9.5 mg/dl), 51.6% had adequate phosphorus (3.5-5.5 mg/dl) and 21.1% displayed acceptable iPTH levels (150-300 pg/ml). 24% had iPTH 300 pg/ml. iPTH ≥600 pg/ml was present in 28.3%, and 13.3% had values ≥1000 pg/ml. These figures differed from those published by the DOPPS II study, in which 51.1% of patients had iPTH hyperparathyroidism, oral or intravenous calcitriol was predominantly used (50.5%) with a small percentage of patients receiving paricalcitol or doxercalciferol. The present study shows a high prevalence of secondary hyperparathyroidism, which differs from that published by other large population studies. There was a high proportion of patients with BMM markers outside the ranges suggested by K/DOQI. Mainly phosphate binders based on calcium and calcitriol continue to be used

    The aim of this project was to detail the costs associated with the high prevalence mental disorders (depression, anxiety-related and substance use) in Australia, using community-based, nationally representative survey data. Respondents diagnosed, within the preceding 12 months, with high prevalence mental disorders using the Confidentialised Unit Record Files of the 2007 National Survey of Mental Health and Wellbeing were analysed. The use of healthcare resources (hospitalisations, consultations and medications), productivity loss, income tax loss and welfare benefits were estimated. Unit costs of healthcare services were obtained from the Independent Hospital Pricing Authority, Medicare and Pharmaceutical Benefits Scheme. Labour participation rates and unemployment rates were determined from the National Survey of Mental Health and Wellbeing. Daily wage rates adjusted by age and sex were obtained from Australian Bureau of Statistics and used to estimate productivity losses. Income tax loss was estimated based on the Australian Taxation Office rates. The average cost of commonly received Government welfare benefits adjusted by age was used to estimate welfare payments. All estimates were expressed in 2013-2014 AUD and presented from multiple perspectives including public sector, individuals, private insurers, health sector and societal. The average annual treatment cost for people seeking treatment was AUD660 (public), AUD195 (individual), AUD1058 (private) and AUD845 from the health sector's perspective. The total annual healthcare cost was estimated at AUD974m, consisting of AUD700m to the public sector, AUD168m to individuals, and AUD107m to the private sector. The total annual productivity loss attributed to the population with high prevalence mental disorders was estimated at AUD11.8b, coupled with the yearly income tax loss at AUD1.23b and welfare payments at AUD12.9b. The population with high prevalence mental disorders not only incurs substantial cost to

    2008-07-01

    Full Text Available Abstract Background A very high prevalence (22.3% of gestational diabetes mellitus (GDM was recently reported following our study on a large group of Sardinian women. In order to explain such a high prevalence we sought to characterise our obstetric population through the analysis of risk factors and their association with the development of GDM. Methods The prevalence of risk factors and their association with the development of GDM were evaluated in 1103 pregnancies (247 GDM and 856 control women. The association of risk factors with GDM was calculated according to logistic regression. Sensitivity and specificity of risk assessment strategy were also calculated. Results None of the risk factors evaluated showed an elevated frequency in our population. The high risk patients were 231 (20.9%. Factors with a stronger association with GDM development were obesity (OR 3.7, 95% CI 2.08–6.8, prior GDM (OR 3.1, 95% CI 1.69–5.69, and family history of Type 2 diabetes (OR 2.6, 95% CI 1.81–3.86. Only patients over 35 years of age were more represented in the GDM group (38.2% vs 22.6% in the non-GDM cases, P P Conclusion Such a high prevalence of GDM in our population does not seem to be related to the abnormal presence of some known risk factors, and appears in contrast with the prevalence of Type 2 diabetes in Sardinia. Further studies are needed to explain the cause such a high prevalence of GDM in Sardinia. The "average risk" definition is not adequate to predict GDM in our population.

  20. Economic impact of HIV and antiretroviral therapy on education supply in high prevalence regions.

    Claire L Risley

    Full Text Available We set out to estimate, for the three geographical regions with the highest HIV prevalence, (sub-Saharan Africa [SSA], the Caribbean and the Greater Mekong sub-region of East Asia, the human resource and economic impact of HIV on the supply of education from 2008 to 2015, the target date for the achievement of Education For All (EFA, contrasting the continuation of access to care, support and Antiretroviral therapy (ART to the scenario of universal access.A costed mathematical model of the impact of HIV and ART on teacher recruitment, mortality and absenteeism (Ed-SIDA was run using best available data for 58 countries, and results aggregated by region. It was estimated that (1 The impact of HIV on teacher supply is sufficient to derail efforts to achieve EFA in several countries and universal access can mitigate this. (2 In SSA, the 2008 costs to education of HIV were about half of those estimated in 2002. Providing universal access for teachers in SSA is cost-effective on education returns alone and provides a return of $3.99 on the dollar. (3 The impacts on education in the hyperendemic countries in Southern Africa will continue to increase to 2015 from its 2008 level, already the highest in the world. (4 If treatment roll-out is successful, numbers of HIV positive teachers are set to increase in all the regions studied.The return on investing in care and support is also greater in those areas with highest impact. SSA requires increased investment in teacher support, testing and particularly ART if it is to achieve EFA. The situation for teachers in the Caribbean and East Asia is similar but on a smaller scale proportionate to the lower levels of infection and greater existing access to care and support.

    The Republic of Djibouti is an African country that exhibits one of the highest incidence rate of tuberculosis in the world. The aim of this study was to evaluate the prevalence of multidrug-resistant tuberculosis among new cases. We studied retrospectively every tuberculosis case diagnosed over a 12-month period in patients hospitalized at the French Military Hospital of Bouffard. During this period, 1,274 samples from 675 patients were tested. We isolated 266 mycobacteria corresponding to 180 cases of tuberculosis. Thirty-three were fully susceptible and 57% met the tuberculosis criteria, with 46% primary resistance. No extensively-drug-resistant tuberculosis was found. Our results highlight a major concern about the situation in this part of the world.

  6. Mexican patients with HIV have a high prevalence of vertebral fractures

    José Antonio Mata-Marín

    2018-04-01

    Full Text Available Low bone mineral density (BMD and fragility fractures are common in individuals infected with HIV, who are undergoing antiretroviral therapy (ART. In high-income countries, dual energy X-ray absorptiometrry is typically used to evaluate osteopenia or osteoporosis in HIV infected individuals. However, this technology is unavailable in low and-middle income countries, so a different approach is needed. The aim of this study was to use X-ray scans of the spine to determine the prevalence of and associated risk factors for vertebral fractures in HIV-infected patients in a tertiary-care hospital in Mexico. We conducted a cross-sectional study of outpatients who were >40 years old and receiving ART at the Hospital de Infectología, La Raza National Medical Center in Mexico City, Mexico. We used semi-quantitative morphometric analysis of centrally digitized X-ray images to assess vertebral deformities in the spine. Anterior, middle and posterior vertebral heights were measured, and height ratios were calculated. For each vertebral body, fractures were graded on the basis of height ratio reductions, and a spine deformity index’ (SDI value was calculated by summing the grades of the vertebral deformities: An SDI>1 was indicative of a vertebral fracture. We included 104 patients, 87% of whom were men. The median age was 49 years [interquartile range (IQR 42-52]. Themost common stage of HIV infection, as defined by the Centers for Disease Control,was B2 in 40 (39% of patients. Forty seven (45% patients were on ART regimens that included protease inhibitors (PIs and 100 (96% being treated with tenofovir. The median time of ART was 6.5 years (IQR1.6-9.0. Of the 104 patients in our study, 83 (80% had undetectable viral load, as assessed by HIV-1 RNA levels, 32 (31% showed evidence of a previous fracture, 4 (4% were co-infected with hepatitis C virus, and 57 (55% had a history of corticosteroid treatment. The prevalence of vertebral fractures was 25%, 95

    Waterborne infections have been shown to be important in outbreaks of gastroenteritis throughout the world. Although improved sanitary conditions are being progressively applied, fecal contaminations remain an emerging problem also in developed countries. The aim of our study was to investigate the prevalence of fecal contaminated water sources in Slovenia, including surface waters and groundwater sources throughout the country. In total, 152 water samples were investigated, of which 72 samples represents groundwater from individual wells, 17 samples from public collection supplies and 63 samples from surface stream waters. Two liters of untreated water samples were collected and concentrated by the adsorption/elution technique with positively charged filters followed by an additional ultracentrifugation step. Group A rotaviruses, noroviruses (genogroups I and II) and astroviruses were detected with real-time RT-PCR method in 69 (45.4%) out of 152 samples collected, of which 31/89 (34.8%) drinking water and 38/63 (60.3%) surface water samples were positive for at least one virus tested. In 30.3% of drinking water samples group A rotaviruses were detected (27/89), followed by noroviruses GI (2.2%; 2/89) and astroviruses (2.2%; 2/89). In drinking groundwater samples group A rotaviruses were detected in 27 out of 72 tested samples (37.5%), genogroup I noroviruses in two (2.8%), and human astroviruses in one (1.4%) samples. In surface water samples norovirus genogroup GII was the most frequently detected (41.3%; 26/63), followed by norovirus GI (33.3%; 21/63), human astrovirus (27.0%; 17/63) and group A rotavirus (17.5%; 11/63). Our study demonstrates relatively high percentage of groundwater contamination in Slovenia and, suggests that raw groundwater used as individual drinking water supply may constitute a possible source of enteric virus infections. In the future, testing for enteric viruses should be applied for drinking water sources in waterborne outbreaks

    2016-01-01

    Background: Anemia is highly prevalent in Cambodian women and children, but data on causes of anemia are scarce. We performed a national micronutrient survey in children and women that was linked to the Cambodian Demographic Health Survey 2014 (CDHS-2014) to assess the prevalence of micronutrient deficiency, hemoglobin disorders and intestinal parasite infection. Methods: One-sixth of households from the CDHS-2014 were selected for a follow-up visit for the micronutrient survey. Households were visited from two weeks to two months after the CDHS-2014 visit. Data on micronutrient status were available for 1512 subjects (792 children and 720 women). Results: Anemia was found in 43% of the women and 53% of the children. Hemoglobin disorders affected >50% of the population, with Hemoglobin-E the most prevalent disorder. Deficiencies of iron (ferritin children, the prevalence of iron, vitamin A, vitamin B12 or folic acid deficiency was anemia in children, whereas in the women none of the factors was significantly associated with anemia. Iron deficiency anemia (IDA) was more prevalent in children children and women, the prevalence of IDA was anemia were hookworm infection and zinc and folic acid deficiency. Over 40% of the anemia was not caused by nutritional factors. Conclusion: The very high prevalence of anemia in Cambodian women and children cannot be explained solely by micronutrient deficiencies and hemoglobin disorders. Micronutrient interventions to improve anemia prevalence are likely to have limited impact in the Cambodian setting. The focus of current interventions to reduce the high prevalence of anemia in children and women should be broadened to include zinc and folic acid as well as effective anti-hookworm measures.

    2011-11-01

    Full Text Available Abstract Background The prevalence of hyperglycaemia and its association with socioeconomic factors have been well studied in developed countries, however, little is known about them in transforming rural China. Methods A cross-sectional study was carried out in 4 rural communities of Deqing County located in East China in 2006-07, including 4,506 subjects aged 18 to 64 years. Fasting plasma glucose (FPG was measured. Subjects were considered to have impaired fasting glucose (IFG if FPG was in the range from 5.6 to 6.9 mmol/L and to have diabetes mellitus (DM if FG was 7.0 mmol/L or above. Results The crude prevalences of IFG and DM were 5.4% and 2.2%, respectively. The average ratio of IFG/DM was 2.5, and tended to be higher for those under the age of 35 years than older subjects. After adjustment for covariates including age (continuous, sex, BMI (continuous, smoking, alcohol drinking, and regular leisure physical activity, subjects in the high household income group had a significantly higher risk of IFG compared with the medium household income group (OR: 1.74, 95% CI: 1.11-2.72 and no significant difference in IFG was observed between the low and medium household income groups. Education and farmer occupation were not significantly associated with IFG. Conclusions High household income was significantly associated with an increased risk of IFG. A high ratio of IFG/DM suggests a high risk of diabetes in foreseeable future in the Chinese transforming rural communities.

  11. Outcomes after chemotherapy with WHO category II regimen in a population with high prevalence of drug resistant tuberculosis.

    Francine Matthys

    Full Text Available Standard short course chemotherapy is recommended by the World Health Organization to control tuberculosis worldwide. However, in settings with high drug resistance, first line standard regimens are linked with high treatment failure. We evaluated treatment outcomes after standardized chemotherapy with the WHO recommended category II retreatment regimen in a prison with a high prevalence of drug resistant tuberculosis (TB. A cohort of 233 culture positive TB patients was followed through smear microscopy, culture, drug susceptibility testing and DNA fingerprinting at baseline, after 3 months and at the end of treatment. Overall 172 patients (74% became culture negative, while 43 (18% remained positive at the end of treatment. Among those 43 cases, 58% of failures were determined to be due to treatment with an inadequate drug regimen and 42% to either an initial mixed infection or re-infection while under treatment. Overall, drug resistance amplification during treatment occurred in 3.4% of the patient cohort. This study demonstrates that treatment failure is linked to initial drug resistance, that amplification of drug resistance occurs, and that mixed infection and re-infection during standard treatment contribute to treatment failure in confined settings with high prevalence of drug resistance.

  14. Extensive dissemination of methicillin-resistant Staphylococcus aureus (MRSA between the hospital and the community in a country with a high prevalence of nosocomial MRSA.

    Diana Espadinha

    Full Text Available According to the EARS-Net surveillance data, Portugal has the highest prevalence of nosocomial methicillin-resistant Staphylococcus aureus (MRSA in Europe, but the information on MRSA in the community is very scarce and the links between the hospital and community are not known. In this study we aimed to understand the events associated to the recent sharp increase in MRSA frequency in Portugal and to evaluate how this has shaped MRSA epidemiology in the community. With this purpose, 180 nosocomial MRSA isolates recovered from infection in two time periods and 14 MRSA isolates recovered from 89 samples of skin and soft tissue infections (SSTI were analyzed by pulsed-field gel electrophoresis (PFGE, staphylococcal chromosome cassette mec (SCCmec typing, spa typing and multilocus sequence typing (MLST. All isolates were also screened for the presence of Panton Valentine leukocidin (PVL and arginine catabolic mobile element (ACME by PCR. The results showed that ST22-IVh, accounting for 72% of the nosocomial isolates, was the major clone circulating in the hospital in 2010, having replaced two previous dominant clones in 1993, the Iberian (ST247-I and Portuguese (ST239-III variant clones. Moreover in 2010, three clones belonging to CC5 (ST105-II, ST125-IVc and ST5-IVc accounted for 20% of the isolates and may represent the beginning of new waves of MRSA in this hospital. Interestingly, more than half of the MRSA isolates (8/14 causing SSTI in people attending healthcare centers in Portugal belonged to the most predominant clones found in the hospital, namely ST22-IVh (n = 4, ST5-IVc (n = 2 and ST105-II (n = 1. Other clones found included ST5-V (n = 6 and ST8-VI (n = 1. None of the MRSA isolates carried PVL and only five isolates (ST5-V-t179 carried ACME type II. The emergence and spread of EMRSA-15 may be associated to the observed increase in MRSA frequency in the hospital and the consequent spillover of MRSA into the community.

  18. High Prevalence of Aleutian Mink Disease Virus in Free-ranging Mink on a Remote Danish Island

    Jensen, Trine Hammer; Christensen, Laurids Siig; Chriél, Mariann

    2012-01-01

    Aleutian mink disease virus (AMDV) causes severe disease in farmed mink (Neovison vison) worldwide. In Denmark, AMDV in farmed mink has been confined to the northern part of the mainland since 2002. From 1998 to 2009, samples from 396 free-ranging mink were collected from mainland Denmark......, and a low AMDV antibody prevalence (3% of 296) was found using countercurrent immune electrophoresis. However, on the island of Bornholm in the Baltic Sea, a high prevalence (45% of 142 mink) was detected in the free-ranging mink. Aleutian mink disease virus was detected by polymerase chain reaction in 32...... of 49 antibody-positive free-ranging mink on Bornholm, but not in mink collected from other parts of Denmark. Sequence analysis of 370 base pairs of the nonstructural gene of the AMDV of 17 samples revealed two clusters with closest similarity to Swedish AMDV strains....

  19. The high prevalence of anemia in Cambodian children and women cannot be satisfactorily explained by nutritional deficiencies or hemoglobin disorders

    Wieringa, Frank Tammo; Dahl, Miriam; Chamnan, Chhoun

    2016-01-01

    BACKGROUND: Anemia is highly prevalent in Cambodian women and children, but data on causes of anemia are scarce. We performed a national micronutrient survey in children and women that was linked to the Cambodian Demographic Health Survey 2014 (CDHS-2014) to assess the prevalence of micronutrient...... for 1512 subjects (792 children and 720 women). RESULTS: Anemia was found in 43% of the women and 53% of the children. Hemoglobin disorders affected >50% of the population, with Hemoglobin-E the most prevalent disorder. Deficiencies of iron (ferritin ... and hemoglobinopathy were significantly associated with anemia in children, whereas in the women none of the factors was significantly associated with anemia. Iron deficiency anemia (IDA) was more prevalent in children

    Deficiencies of micronutrients can affect the growth and development of children. There is increasing evidence of vitamin D deficiency world-wide resulting in nutritional rickets in children and osteoporosis in adulthood. Data on the micronutrient status of children in Malaysia is limited. The aim of this study was to determine the anthropometric and micronutrient status of primary school children in the capital city of Kuala Lumpur. A cross sectional study of primary aged school children was undertaken in 2008. A total of 402 boys and girls aged 7-12 years, attending primary schools in Kuala Lumpur participated in the study. Fasting blood samples were taken to assess vitamin D [as 25(OH)D], vitamin B12, folate, zinc, iron, and ferritin and haemoglobin concentrations. Height-for-age and body mass index for age (BMI-for-age) of the children were computed. Most of the children had normal height-for-age (96.5%) while slightly over half (58.0%) had normal BMI-for-age. A total of 17.9% were overweight and 16.4% obese. Prevalence of obesity was significantly higher among the boys (25%) than in the girls (9.5%) (χ2 = 22.949; P 37.5-≤ 50 nmol/L). Among the boys, a significant inverse association was found between serum vitamin D status and BMI-for-age (χ2 = 5.958; P = .016). This study highlights the presence of a high prevalence of sub-optimal vitamin D status among urban primary school children in a tropical country. In light of the growing problem of obesity in Malaysian children, these findings emphasize the important need for appropriate interventions to address both problems of obesity and poor vitamin D status in children.

    Cardiovascular diseases are one of the leading causes of death in India. There is high prevalence of cardiovascular risk factors in urban Tamil Nadu. There are limited data on the prevalence of behavioral risk factors and overweight in rural Tamil Nadu. We estimated prevalence of behavioral risk factors, overweight and central obesity in a rural population in Tamil Nadu, India. We conducted a cross-sectional survey in 11 villages in Kancheepuram/Thiruvallur districts, Tamil Nadu. Study population included 10,500 subjects aged 25-64 years. We collected data on behavioral risk factors and anthropometric measurements. Body mass index (BMI) was categorized using the classification recommended for Asians. Central obesity was defined as waist circumference ≥90 cm for men and ≥80 cm for women. We computed proportions for all risk factors and used trend chi-square to examine trend. Among the 10,500 subjects, 4927 (47%) were males. Among males, 1852 (37.6%) were current smokers and 3073 (62.4%) were current alcohol users. Among females, 840 (15.1%) were smokeless tobacco users. BMI was ≥23.0 kg/m 2 for 1618 (32.8%) males and 2126 (38.2%) females. 867 (17.6%) males and 1323 (23.7%) females were centrally obese. Most commonly used edible oil was palm oil followed by sunflower oil and groundnut oil. We observed high prevalence of tobacco use, alcohol use and central obesity in the rural population in Tamil Nadu. There is need for health promotion programs to encourage adoption of healthy lifestyle and policy interventions to create enabling environment.

    Use of antibiotics in food animals may contribute to development and spread of resistant organisms, particularly so in some countries. The aim of this study was two-fold; first, to establish the prevalence of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in chicken production in a region within Romania. Second, to study the relatedness of ESBL-producing E. coli isolates recovered from broilers, abattoir workers where the chickens were slaughtered and from the human clinical specimens from two regional hospitals. The results indicated a very high (69%) rate of carriage of ESBL and AmpC-producing E. coli in chickens with 36% CTX-M producers. Sequencing showed that chickens in Romania have the highest worldwide prevalence (53%) of blaCTX-M-15 reported in poultry E. coli isolates. The majority (53%) of the extended-spectrum cephalosporin-resistant E. coli carried plasmid-mediated blaampC genes, mostly blaCMY-2 type, one of the highest prevalences reported in Europe. The predominant CTX-M type found in the human clinical E. coli isolates was blaCTX-M-15 and most isolates coharbored blaOXA-1, blaTEM, and aac(6')-ib-cr. The majority (60%) of the human clinical isolates belonged to the pandemic virulent clone B2-ST131. The clonal relationship between broiler and the human CTX-M-producing E. coli isolates was assessed by macrorestriction pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST), which indicated strain diversity with no common STs found between human and poultry isolates. Moreover, IncI1 was the most prevalent replicon found in broiler ESBL-producing E. coli isolates and also in transconjugants, indicating that plasmids and not clonal spread may play a role in the transfer of blaCTX-M genes. This study identifies a high prevalence of ESBL-producing E. coli from broiler chickens in Romania with a high occurrence incidence of blaCTX-M-15, which reflects the main ESBL type found in human E. coli infections in this

  4. Co-Circulation of Canine Coronavirus I and IIa/b with High Prevalence and Genetic Diversity in Heilongjiang Province, Northeast China.

    Xinyu Wang

    Full Text Available To trace the evolution of canine coronavirus (CCoV, 201 stool samples from diarrheic dogs in northeast China were subjected to reverse transcription-polymerase chain reactions (RT-PCRs targeting the partial M and S genes of CCoV, followed by an epidemiological analysis. M gene RT-PCRs showed that 28.36% (57/201 of the samples were positive for CCoV; of the 57 positive samples, CCoV-I and CCoV-II accounted for 15.79% (9/57 and 84.21% (48/57, respectively. A sequence comparison of the partial M gene revealed nucleotide homologies of 88.4%-100% among the 57 CCoV strains, and 88.7%-96.2% identity between the 57 CCoV strains and the Chinese reference strain HF3. The CCoV-I and CCoV-II strains exhibited genetic diversity when compared with reference strains from China and other countries. The 57 CCoV strains exhibited high co-infection rates with canine kobuvirus (CaKV (33.33% and canine parvovirus-2 (CPV-2 (31.58%. The CCoV prevalence in diarrheic dogs differed significantly with immunization status, regions, seasons, and ages. Moreover, 28 S genes were amplified from the 57 CCoV-positive samples, including 26 CCoV-IIa strains, one CCoV-IIb strain, and one CCoV-I strain. A sequence comparison of the partial S gene revealed 86.3%-100% nucleotide identity among the 26 CCoV-IIa strains, and 89.6%-92.2% identity between the 26 CCoV-IIa strains and the Chinese reference strain V1. The 26 CCoV-IIa strains showed genetic diversity when compared with reference strains from China and other countries. Our data provide evidence that CCoV-I, CCoV-IIa, and CCoV-IIb strains co-circulate in the diarrhoetic dogs in northeast China, high co-infection rates with CaKV and CPV-2 were observed, and the CCoV-II strains exhibited high prevalence and genetic diversity.

    2009-06-01

    The expansion of HIV/AIDS care and treatment in resource-constrained countries, especially in sub-Saharan Africa, has generally developed in a top-down manner. Further expansion will involve primary health centers where human and other resources are limited. This article describes the World Health Organization/President's Emergency Plan for AIDS Relief collaboration formed to help scale up HIV services in primary health centers in high-prevalence, resource-constrained settings. It reviews the contents of the Operations Manual developed, with emphasis on the Laboratory Services chapter, which discusses essential laboratory services, both at the center and the district hospital level, laboratory safety, laboratory testing, specimen transport, how to set up a laboratory, human resources, equipment maintenance, training materials, and references. The chapter provides specific information on essential tests and generic job aids for them. It also includes annexes containing a list of laboratory supplies for the health center and sample forms.

  6. [High prevalence of work-family conflict among female physicians: lack of social support as a potential antecedent].

    Adám, Szilvia

    2009-12-13

    According to stress theory, social support from work and non-work-related sources may influence the level of perceived work-family conflict. Despite the high prevalence of work-family conflict as a source of distress among female physicians, no information is available on the associations between work-family conflict and social support in a traditional, family-centric cultural setting, where female role expectations are demanding. The author hypothesized that high prevalence of work-family conflict could be attributed to the lack of social support among female physicians. To investigate the prevalence and psychosocial characteristics of social support and its relations to work-family conflict among female physicians. Quantitative and qualitative study using questionnaires ( n = 420) and in-depth interviews ( n = 123) among female and male physicians. Female physicians reported significantly higher mean level and prevalence of work-family conflict compared to men. The predominant form of work-family was work-to-family conflict among physicians; however, significantly more female physicians experienced family-to-work conflict and strain-based work-family conflict compared to men (39% vs. 18% and 68% vs. 20%, respectively). Significantly more male physicians experienced time-based work-family conflict compared to women. Content analyses of interview data revealed that provision of support to physicians manifested itself in parental support in career selection, spousal support with household duties, peer support with enabling access to professional role models-mentors, peer support to ensure gender equity, and organizational support with family-centric policies. Female physicians reported significantly less parental, spousal, and peer support compared to men. Female physicians lacking parental, peer, or organizational support experienced significantly higher level of work-family conflict compared to appropriate control. In regression analyses, high job demands, job

  8. Regulated Medicare Advantage And Marketplace Individual Health Insurance Markets Rely On Insurer Competition.

    Frank, Richard G; McGuire, Thomas G

    2017-09-01

    Two important individual health insurance markets-Medicare Advantage and the Marketplaces-are tightly regulated but rely on competition among insurers to supply and price health insurance products. Many local health insurance markets have little competition, which increases prices to consumers. Furthermore, both markets are highly subsidized in ways that can exacerbate the impact of market power-that is, the ability to set price above cost-on health insurance prices. Policy makers need to foster robust competition in both sectors and avoid designing subsidies that make the market-power problem worse. Project HOPE—The People-to-People Health Foundation, Inc.

  9. High Prevalence of Diabetes and Prediabetes and Their Coexistence with Cardiovascular Risk Factors in a Hispanic Community

    Soto-Salgado, Marievelisse; Suárez, Erick; Guzmán, Manuel; Ortiz, Ana Patricia

    2014-01-01

    This study examined the prevalence and association of diabetes mellitus (DM) and prediabetes with cardiovascular risk factors among Puerto Ricans adults. Data from a household survey of 857 adults aged 21–79 years who underwent interviews, physical exams, and blood draws were analyzed. Prevalence of total DM and prediabetes was estimated using American Diabetes Association diagnostic criteria of fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c). Poisson regression models were used to estimate the prevalence ratio for each cardiovascular risk factor under study. Age-standardized prevalence of total DM and prediabetes, detected by FPG and/or HbA1c, was 25.5 and 47.4 %, respectively. Compared with participants with normoglycemia, those with previously diagnosed DM, undiagnosed DM, and prediabetes had more adverse cardiovascular risk factor profiles, characterized by a higher prevalence of general and abdominal obesity, hypertension, low HDL cholesterol, elevated LDL cholesterol, elevated triglycerides, and elevated plasminogen activator inhibitor 1 (p < 0.05). The high prevalence of DM and prediabetes calls for public health actions to plan and implement lifestyle interventions to prevent or delay the onset of DM and cardiovascular disease. PMID:24781780

  10. Limited referral to nephrologists from a tertiary geriatric outpatient clinic despite a high prevalence of chronic kidney disease and anaemia

    Boudville Neil

    2012-08-01

    Full Text Available Abstract Background Chronic kidney disease (CKD is increasing in prevalence world-wide with the largest growth being in the elderly. The aim of this study was to examine the prevalence of CKD in a geriatric outpatient clinic within a tertiary hospital and its association with anaemia and mortality with a focus on the referral patterns towards nephrologists. Methods Retrospective study utilising administrative databases. The cohort was defined as all patients that attended the geriatric outpatient clinics of a single tertiary hospital within the first 3 months of 2006. Patients were followed for 18 months for mortality and referral to a nephrologist. Results The mean Glomerular filtration rate (eGFR of the 439 patients was 67.4 ± 29.1 mL/min/1.73 m2 (44% 2. 11.8% had a haemoglobin 2 (p = 0.0092. Kidney function and anaemia were significantly associated with mortality on multivariate analysis (p = 0.019 and p = 0.0074. After 18 months, 8.8% of patients with CKD were referred to a nephrologist. Conclusion Despite a high prevalence of CKD in patients attending a geriatric outpatient clinic and its association with anaemia and mortality, few of these patients were referred to a nephrologist. An examination of the reasons behind this bias is required.

  11. High prevalence of Hepatozoon-infection among shepherd dogs in a region considered to be free of Rhipicephalus sanguineus.

    2013-09-01

    Blood samples and ticks were collected from 100 shepherd dogs, 12 hunting dogs and 14 stray dogs in southern Hungary, in order to screen them for the presence of Hepatozoon spp. by PCR. Out of 126 blood samples, 33 were positive (26%). Significantly more shepherd dogs (31%) were infected, than hunting (8%) and stray dogs (7%). Three genotypes of Hepatozoon canis were identified by sequencing, differing from each other in up to six nucleotides in the amplified portion of their 18S rRNA gene. In Dermacentor marginatus larvae/nymphs and Dermacentor reticulatus nymphs, H. canis was present only if they had been collected from PCR-positive dogs, and the genotypes were identical in the ticks and their hosts. However, two Haemaphysalis concinna nymphs removed from a PCR-negative dog were found positive for H. canis, and the genotype detected in specimens of this tick species differed from that in the blood of their respective hosts. These results indicate that canine hepatozoonosis may be highly prevalent in regions where Rhipicephalus sanguineus is considered to be non-endemic. In addition, H. canis was identified for the first time in Hungary, as well as in D. marginatus, D. reticulatus and Ha. concinna ticks. Canine hepatozoonosis was significantly more prevalent west of the Danube river (where higher densities of red fox and golden jackal populations occur), suggesting a role of wild carnivores in its epidemiology.

  12. Parasites of importance for human health in Nigerian dogs: high prevalence and limited knowledge of pet owners.

    Ugbomoiko, Uade Samuel; Ariza, Liana; Heukelbach, Jorg

    2008-12-09

    Dogs are the most common pet animals worldwide. They may harbour a wide range of parasites with zoonotic potential, thus causing a health risk to humans. In Nigeria, epidemiological knowledge on these parasites is limited. In a community-based study, we examined 396 dogs in urban and rural areas of Ilorin (Kwara State, Central Nigeria) for ectoparasites and intestinal helminths. In addition, a questionnaire regarding knowledge and practices was applied to pet owners. Nine ectoparasite species belonging to four taxa and six intestinal helminth species were identified: fleas (Ctenocephalides canis, Pulex irritans, Tunga penetrans), mites (Demodex canis, Otodectes sp., Sarcoptes scabiei var. canis), ticks (Rhipicephalus sanguineus, Ixodes sp.), and lice (Trichodectes canis); and Toxocara canis, Ancylostoma sp., Trichuris vulpis, Dipylidium caninum, Taenidae and Strongyloides sp. Overall prevalence of ectoparasites was 60.4% and of intestinal helminths 68.4%. The occurrence of C. canis, R. sanguineus, T. canis, Ancylostoma sp. and T. vulpis was most common (prevalence 14.4% to 41.7%). Prevalence patterns in helminths were age-dependent, with T. canis showing a decreasing prevalence with age of host, and a reverse trend in other parasite species. Knowledge regarding zoonoses was very limited and the diseases not considered a major health problem. Treatment with antiparasitic drugs was more frequent in urban areas. Parasites of importance for human health were highly prevalent in Nigerian dogs. Interventions should include health education provided to dog owners and the establishment of a program focusing on zoonotic diseases.

    Vitamin D is important in promoting healthy pregnancy and fetal development. We undertook this study to measure 25-hydroxyvitamin D in maternal and cord blood and to identify maternal factors related to vitamin D status in Calgary. Blood samples collected at the time of delivery from the Alberta Pregnancy Outcomes and Nutrition study cohort (ApronStudy.ca) participants were processed for plasma and assayed using liquid chromatography mass spectrometry methodology for 25(OH)D 3 . Ninety-two pairs of maternal and cord blood samples were obtained. The prevalence of 25(OH)D 3 insufficiency-25(OH)D 3 <75 nmol/L-was 38% and 80% in women and neonates, respectively. Vitamin D supplementation was the only clinical factor associated with 25(OH)D 3 sufficiency, and the odds of sufficiency were 3.75 (95% CI 1.00 to 14.07) higher for women and 5.27 (95% CI 1.37 to 20.27) when over 2000 IU/day were used. Using liquid chromatography mass spectrometry, we demonstrated a very high prevalence of vitamin D insufficiency in cord blood and that the use of high dose vitamin D was associated with greater odds of sufficiency in pregnant women and cord blood in Alberta.

    2012-05-01

    Full Text Available Abstract Background Both colorectal cancer (CRC and diabetes mellitus (DM are important public health problems worldwide. As there are controversies about survival impact on CRC patients with preexisting DM, the purpose of the present study is to evaluate the incidence and the survival impact of preexisting DM on the long-term outcomes of patients with CRC in Taiwan. Methods From January 2002 to December 2008, 1,197 consecutive patients with histologically proven primary CRC, who received surgical treatment at a single institution, were enrolled. The clinicopathologic features between these patients with and without DM were retrospectively investigated. Moreover, we intended to analyze the impact of DM on overall survival (OS and cancer-specific survival (CSS rates. Results Of 1,197 CRC patients, 23.6% of patients had either a reported history of DM or were currently taking one or more diabetes-controlling medications. CRC patients with DM were significantly older than those without DM (P P vs 6.01%, P = 0.040. Conclusions A considerably high prevalence of DM in CRC patients but no significant impact of DM on survival was observed in the single-institution retrospective study, regardless of cancer stages and tumor locations. Therefore, treatment strategies for CRC patients with DM should be the same as patients without DM.

  15. High prevalence of sedentary risk factors amongst university employees and potential health benefits of campus workplace exercise intervention.

    Alkhatib, Ahmad

    2015-01-01

    Sedentariness and physical inactivity are often reported within white-collar workers, including university campus employees. However, the prevalence of the associated sedentary risk factors and risk reduction intervention strategies within a university campus workplace are less known. This study investigates whether the prevalence of sedentary risk factors within university campus employees could be reduced with a campus based exercise intervention. 56 UK university employees (age = 50.7 ± 10.2, stature = 1.68.8 ± 8.6, body mass = 73.9 ± 15.1) were tested for body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP) and maximal cardiorespiratory capacity (V̇O2max). The prevalence was analyzed across genders and job roles. An exercise intervention followed for the sedentary employees involving walking and running for 25 min twice/week for 10 weeks at an intensity corresponding to individual's ventilatory threshold (VT). The university workplace demonstrated a prevalence of higher BMI, SBP and DBP than the recommended healthy thresholds, with gender having a significant effect. Males' BMI, SBP and DBP were higher than in females (p employees have a high prevalence of sedentary risk factors across different genders and job roles. These risks can be reduced by an exercise-based intervention administered within the campus workplace, which should be considered in university workplace policies.

    Facial trauma in sports has been associated with temporomandibular disorders. Because of the intensity and duration of training needed for elite-level competitions, high-performance athletes can have two to five times more traumatic injuries than recreational athletes. This study aimed to investigate the prevalence of temporomandibular disorders in high-performance martial arts fighters and compare it with the prevalence in recreational athletes and non-athletes. The Research Diagnostic Criteria for Temporomandibular Disorders was used to diagnose and classify professional karate-do practitioners (group I; n = 24), amateur karate-do practitioners (group II; n = 17), high-performance mixed martial arts fighters (group III; n = 13), and non-athletes (n = 28). The groups were compared with the chi-square test and tested for the difference between two proportions using a significance level of 5% (P 0.05). A diagnosis of arthralgia from disk displacement was made more frequently in groups I (45.8%; P = 0.013) and III (38.5%; P = 0.012) than in group IV (7.1%). The chronic pain associated with TMD was low intensity and low disability. While there was a high prevalence of temporomandibular disorders in the professional athletes in our study, the prevalence of the condition in recreational athletes was similar to that in individuals who did not practice martial arts. © 2015 John Wiley & Sons A/S.

    To determine whether the elephantiasis in Midakegn district, central Ethiopia, is filarial or non-filarial (podoconiosis) using serological, parasitological and clinical examinations, and to estimate its prevalence. At house-to-house visits in 330 randomly selected households, all household members who had elephantiasis were interviewed and clinically examined at the nearby health centre to confirm the presence of elephantiasis, check the presence of scrotal swelling and rule out the other causes of lymphoedema. A midnight blood sample was obtained from each participant with elephantiasis for microscopic examination of Wuchereria bancrofti microfilaria. A daytime blood sample was obtained from half of the participants for serological confirmation using the immuno-chromatographic test card. Consistent with the features of podoconiosis, none of the elephantiasis cases had consistently worn shoes since childhood; 94.3% had bilateral swelling limited below the level of the knees; no individual had thigh or scrotal elephantiasis; parasitological test for microfilariae and serological tests for W. bancrofti antigen were negative in all samples. The prevalence of the disease was 7.4% and it peaked in the third decade of life, the most economically active age. Midakegn District has a high prevalence of podoconiosis and no filarial elephantiasis. Prevention, treatment and control of podoconiosis must be among the top priorities of public health programmes. © 2012 Blackwell Publishing Ltd.

    The prevalence of mild adverse reactions, i.e. complaints, in tattoos is sparsely described. The demography of tattoos in a young population representing an index population of the recent trend was studied. The prevalence of complaints related to tattoos, and tattoos by number, size, localization and colour were registered. The data were collected through personal interviews and examinations of consecutive individuals who spontaneously attended a clinic of venereology. Of 154 participants with 342 tattoos, 27% reported complaints in a tattoo beyond 3 months after tattooing. The complaints were predominantly related to black and red pigments. The participants reported complaints in 16% of their tattoos. Fifty-eight per cent of those complaints were sun induced. The complaints varied in intensity but were mainly minor. Skin elevation and itching were most frequent. The responders stated overall satisfaction with 80% of all tattoos. Eight per cent of tattoos were situated on anatomical sites prohibited by Danish law. We found a remarkably high prevalence of tattoo complaints, including photosensitivity, among young individuals tattooed with carbon black and organic pigments especially red. © 2012 The Authors.

  19. Impairments in static standing balance are highly prevalent among older adults receiving home-based physical therapy.

    Bohannon, Richard W

    2012-01-01

    Measures of balance are an important component of the physical therapist examination. This study investigated the usefulness of timed static stance durations for identifying balance impairments among patients receiving home-based physical therapy. This study involved the retrospective retrieval of data from the records of 48 patients at least 60 years of age. Their balance was measured under 3 foot configurations; that is, feet apart, feet together, and on each foot. Every patient demonstrated impaired standing balance. Most, but not all could balance 30 seconds with the feet apart or together. Only 19 could maintain balance on each of both feet. Of those who could so balance, none was able to achieve the average time of normal individuals of comparable age. Although not able to identify all aspects of balance, timed durations of stance under different configurations demonstrate a high prevalence of balance impairments among patients receiving home-based physical therapy. As the tests are objective, fast, and require little space, they can be advocated in such a setting.

  20. Genital herpes stigma: Toward the Measurement and Validation of a highly prevalent yet hidden public health problem.

    2018-02-01

    Despite its highly prevalent and stigmatizing nature, genital herpes has received little attention from stigma researchers relative to other sexually transmitted infections. This limitation is of great relevance to researchers and practitioners in both clinical and healthcare settings, given that stigma can cause psychological distress and hinder disclosure to sexual partners, hence contributing to the spread of genital herpes. The present research developed and examined the psychometric properties of a quantitative measure of genital herpes stigma. Two hundred individuals diagnosed with genital herpes recruited through online genital herpes support groups completed a survey containing 37 items adapted from the HIV Stigma Scale, questions about demographic and herpes-related characteristics, and measures of relevant psychosocial variables. A confirmatory factor analysis yielded an 18-item scale with four factors: personalized stigma, disclosure concerns, negative self-image, and concern with public attitudes. All subscales demonstrated good internal consistency, with Cronbach alphas ranging from 0.74 to 0.87. Construct validity was supported by correlations with relevant psychosocial variables, including negative affect, rumination, and perceived social support. As a psychometrically sound assessment tool, the Genital Herpes Stigma Scale can be used in both clinical and research settings to facilitate future efforts to alleviate the negative psychological consequences of this incurable viral infection.

    Rourk, Angela R; Nolte, Frederick S; Litwin, Christine M

    2016-11-01

    With the recent introduction of automated treponemal tests, a new reverse syphilis algorithm has been proposed and now used by many clinical laboratories. We analyzed the impact of instituting the reverse screening syphilis algorithm in a laboratory that serves a geographic area with a moderately high prevalence of syphilis infection. Serum samples sent for syphilis testing were tested using a treponemal enzyme immunoassay (EIA) as the screening assay. EIA reactive samples were tested by rapid plasma reagin (RPR) and titered to end point if reactive. RPR nonreactive samples were analyzed by the Treponema pallidum particle agglutination test (TP-PA). Pertinent medical records were reviewed for false-reactive screens and samples with evidence of past syphilis infection. Among 10,060 patients tested, 502 (5%) were reactive on the initial EIA screen. The RPR was reactive in 150 (1.5%). TP-PA testing determined that 103 (1.0%) were falsely reactive on initial EIA screen. The reverse screening algorithm, however, identified 242 (2.4%) with evidence of latent, secondary, or past syphilis, 21 of whom had no or unknown prior treatment with antibiotics. Despite a 1.0% false-reactive rate, the reverse syphilis algorithm detected 21 patients with possible latent syphilis that may have gone undetected by traditional syphilis screening. © American Society for Clinical Pathology, 2016.

    Identification of risk factors within precursor syndromes, such as depression, anxiety or substance use disorders (SUD), might help to pinpoint high-risk stages where preventive interventions for Bipolar Disorder (BD) could be evaluated. We examined baseline demographic, clinical, quality of life, and temperament measures along with risk clusters among 52 young people seeking help for depression, anxiety or SUDs without psychosis or BD. The risk clusters included Bipolar At-Risk (BAR) and the Bipolarity Index as measures of bipolarity and the Ultra-High Risk assessment for psychosis. The participants were followed up for 12 months to identify conversion to BD. Those who converted and did not convert to BD were compared using Chi-Square and Mann Whitney U tests. The sample was predominantly female (85%) and a majority had prior treatment (64%). Four participants converted to BD over the 1-year follow up period. Having an alcohol use disorder at baseline (75% vs 8%, χ(2)=14.1, pdepressive symptoms and cannabis use had high effects sizes of association with BD outcomes, without statistical significance. The small number of conversions limited the power of the study to identify associations with risk factors that have previously been reported to predict BD. However, subthreshold affective symptoms and SUDs might predict the onset of BD among help-seeking young people with high-prevalence disorders. Copyright © 2015 Elsevier B.V. All rights reserved.

  3. Anemonefishes rely on visual and chemical cues to correctly identify conspecifics

    Johnston, Nicole K.; Dixson, Danielle L.

    2017-09-01

    Organisms rely on sensory cues to interpret their environment and make important life-history decisions. Accurate recognition is of particular importance in diverse reef environments. Most evidence on the use of sensory cues focuses on those used in predator avoidance or habitat recognition, with little information on their role in conspecific recognition. Yet conspecific recognition is essential for life-history decisions including settlement, mate choice, and dominance interactions. Using a sensory manipulated tank and a two-chamber choice flume, anemonefish conspecific response was measured in the presence and absence of chemical and/or visual cues. Experiments were then repeated in the presence or absence of two heterospecific species to evaluate whether a heterospecific fish altered the conspecific response. Anemonefishes responded to both the visual and chemical cues of conspecifics, but relied on the combination of the two cues to recognize conspecifics inside the sensory manipulated tank. These results contrast previous studies focusing on predator detection where anemonefishes were found to compensate for the loss of one sensory cue (chemical) by utilizing a second cue (visual). This lack of sensory compensation may impact the ability of anemonefishes to acclimate to changing reef environments in the future.

    2011-02-01

    Full Text Available Abstract Background Deficiencies of micronutrients can affect the growth and development of children. There is increasing evidence of vitamin D deficiency world-wide resulting in nutritional rickets in children and osteoporosis in adulthood. Data on the micronutrient status of children in Malaysia is limited. The aim of this study was to determine the anthropometric and micronutrient status of primary school children in the capital city of Kuala Lumpur. Methods A cross sectional study of primary aged school children was undertaken in 2008. A total of 402 boys and girls aged 7-12 years, attending primary schools in Kuala Lumpur participated in the study. Fasting blood samples were taken to assess vitamin D [as 25(OHD], vitamin B12, folate, zinc, iron, and ferritin and haemoglobin concentrations. Height-for-age and body mass index for age (BMI-for-age of the children were computed. Results Most of the children had normal height-for-age (96.5% while slightly over half (58.0% had normal BMI-for-age. A total of 17.9% were overweight and 16.4% obese. Prevalence of obesity was significantly higher among the boys (25% than in the girls (9.5% (χ2 = 22.949; P 12. In contrast, 35.3% of the children had serum 25(OHD concentrations indicative of vitamin D deficiency(≤37.5 nmol/L and a further 37.1% had insufficiency concentrations (> 37.5-≤50 nmol/L. Among the boys, a significant inverse association was found between serum vitamin D status and BMI-for-age (χ2 = 5.958; P = .016. Conclusions This study highlights the presence of a high prevalence of sub-optimal vitamin D status among urban primary school children in a tropical country. In light of the growing problem of obesity in Malaysian children, these findings emphasize the important need for appropriate interventions to address both problems of obesity and poor vitamin D status in children.

    The purpose of this study was to describe the prevalence of dysfunctional, asymmetrical, and painful movement in junior Australian Football players using the Functional Movement Screen (FMS). Cross-sectional study. Elite junior male Australian Football players (n=301) aged 15-18 years completed pre-season FMS testing. The FMS consists of 7 sub-tests: deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, trunk stability push-up (TSPU) and rotary stability. The shoulder mobility, TSPU, and rotary stability tests were combined with an accompanying clearing test to assess pain. Each sub-test was scored on an ordinal scale from 0 to 3 and summed to give a composite score out of 21. Composite scores ≤14 were operationally defined as indicating dysfunctional movement. Players scoring differently on left and right sides were considered asymmetrical. Players reported whether they missed any games due to injury in the preceding 22 game season. Sixty percent of players (n=182) had composite scores ≤14, 65% of players (n=196) had at least one asymmetrical sub-test, and 38% of players (n=113) had at least one painful sub-test. Forty-two percent of players (n=126) missed at least one game in the previous season due to injury. Previous injury did not influence composite score (p=0.951) or asymmetry (p=0.629). Players reporting an injury during the previous season were more likely to experience pain during FMS testing (odds ratio 1.97, 95% confidence interval 1.23-3.18; p=0.005). Junior Australian Football players demonstrate a high prevalence of dysfunctional, asymmetrical, and painful movement during FMS testing. Copyright © 2016 Sports Medicine Australia.

    2015-03-01

    An investigation was conducted in a population of paediatric patients with a high risk of caries in order to assess the association between caries history (CH) and the number of early carious lesions (ECLs) and the frequency and timing of cariogenic food and beverage intake, sugar-containing medication, the frequency and efficacy of tooth brushing, and the use of topical fluorides. Study design: descriptive study. One hundred children aged 6-15 years with≥ ECL of a permanent tooth and not enrolled in any dental health educational or preventive programme were selected. For diagnosis it was used an explorer according to the ICDAS II criteria. The participants completed a closed-list questionnaire on the frequency and timing of cariogenic food intake. There was a nonsignificant tendency to present more ECLs and a greater CH among patients who consumed cariogenic foods and beverages. A significant relationship (pcariogenic beverages and the number of ECL or CH. Using the number of ECLs as dependent variable, regular fluoridated rinses (p=0.003), frequent sugar-containing medication (p=0.007), and cariogenic beverage consumption (p=0.024) were identified as explanatory parameters in the linear regression model. The Student t-test was used to compare ECL and CH with dietetic factors, fluoridated rinses, sugar- containing medicines, and the frequency and efficacy of tooth brushing. Linear regression analysis correlated the number of ECLs to the mentioned explanatory variables. The frequent consumption of sugary beverages and medications, and failure to regularly use fluoridated rinses, were positively correlated to an increased number of ECLs in patients with a high prevalence of caries.

  9. Parasites of importance for human health in Nigerian dogs: high prevalence and limited knowledge of pet owners

    2008-12-01

    Full Text Available Abstract Background Dogs are the most common pet animals worldwide. They may harbour a wide range of parasites with zoonotic potential, thus causing a health risk to humans. In Nigeria, epidemiological knowledge on these parasites is limited. Methods In a community-based study, we examined 396 dogs in urban and rural areas of Ilorin (Kwara State, Central Nigeria for ectoparasites and intestinal helminths. In addition, a questionnaire regarding knowledge and practices was applied to pet owners. Results Nine ectoparasite species belonging to four taxa and six intestinal helminth species were identified: fleas (Ctenocephalides canis, Pulex irritans, Tunga penetrans, mites (Demodex canis, Otodectes sp., Sarcoptes scabiei var. canis, ticks (Rhipicephalus sanguineus, Ixodes sp., and lice (Trichodectes canis; and Toxocara canis, Ancylostoma sp., Trichuris vulpis, Dipylidium caninum, Taenidae and Strongyloides sp. Overall prevalence of ectoparasites was 60.4% and of intestinal helminths 68.4%. The occurrence of C. canis, R. sanguineus, T. canis, Ancylostoma sp. and T. vulpis was most common (prevalence 14.4% to 41.7%. Prevalence patterns in helminths were age-dependent, with T. canis showing a decreasing prevalence with age of host, and a reverse trend in other parasite species. Knowledge regarding zoonoses was very limited and the diseases not considered a major health problem. Treatment with antiparasitic drugs was more frequent in urban areas. Conclusion Parasites of importance for human health were highly prevalent in Nigerian dogs. Interventions should include health education provided to dog owners and the establishment of a program focusing on zoonotic diseases.

  10. High Prevalence of Hyper-Aerotolerant Campylobacter jejuni in Retail Poultry with Potential Implication in Human Infection.

    Oh, Euna; McMullen, Lynn; Jeon, Byeonghwa

    2015-01-01

    Campylobacter jejuni is a leading cause of foodborne illnesses around the world. Since C. jejuni is microaerophilic and sensitive to oxygen, aerotolerance is important in the transmission of C. jejuni to humans via foods under aerobic conditions. In this study, 70 C. jejuni strains were isolated from retail raw chicken meats and were subject to multilocus sequence typing (MLST) analysis. In the aerotolerance testing by aerobic shaking at 200 rpm, 50 (71.4%) isolates survived after 12 h (i.e., aerotolerant), whereas 20 (28.6%) isolates did not (i.e., aerosensitive). Interestingly, further aerobic cultivation showed that 25 (35.7%) isolates still survived even after 24 h of vigorous aerobic shaking (i.e., hyper-aerotolerant). Compared to aerosensitive strains, the hyper-aerotolerant strains exhibited increased resistance to oxidative stress, both peroxide and superoxide. A mutation of ahpC in hyper-aerotolerant strains significantly impaired aerotolerance, indicating oxidative stress defense plays an important role in hyper-aerotolerance. The aerotolerant and hyper-aerotolerant strains were primarily classified into MLST clonal complexes (CCs)-21 and -45, which are known to be the major CCs implicated in human gastroenteritis. Compared to the aerosensitive strains, CC-21 was more dominant than CC-45 in aerotolerant and hyper-aerotolerant strains. The findings in this study revealed that hyper-aerotolerant C. jejuni is highly prevalent in raw chicken meats. The enhanced aerotolerance in C. jejuni would impact human infection by increasing possibilities of the foodborne transmission of C. jejuni under aerobic conditions.

  11. Extreme high prevalence of a defective mannose-binding lectin (MBL2 genotype in native South American West Andean populations.

    José Raul Sandoval

    Full Text Available Mannose-binding lectin (MBL is one of the five recognition molecules in the lectin complement pathway. Common variant alleles in the promoter and structural regions of the human MBL gene (MBL2 influence the stability and serum concentration of the protein. Epidemiological studies have shown that MBL2 variant alleles are associated with susceptibility to and the course of different types of infectious and inflammatory conditions. However, it has been suggested that these alleles are maintained in different populations due to selected advantages for carriers. We investigated the MBL2 allelic variation in indigenous individuals from 12 different West Central South America localities spanning from the desert coast, high altitude Andean plates and the Amazon tropical forest within the territories of Peru (n = 249 (Departments of Loreto, Ucayali, Lambayeque, Junin, Ayacucho, Huancayo and Puno, and Ecuador (n = 182 (Region of Esmeraldas and Santo Domingo de los Colorados. The distribution of MBL2 genotypes among the populations showed that the defective variant LYPB haplotype was very common. It showed the highest frequencies in Puno (Taquile (0.80, Amantani (0.80 and Anapia (0.58 islander communities of the Lake Titicaca, but lower frequencies of 0.22 in Junin (Central Andean highland and Ucayali (Central Amazonian forest, as well as 0.27 and 0.24 in the Congoma and Cayapa/Chachis populations in the Amazonian forest in Ecuador were also observed. Our results suggest that the high prevalence of the MBL2 LYPB variant causing low levels of functional MBL in serum may mainly reflect a random distribution due to a population bottleneck in the founder populations.

    Malnutrition and food insecurity are associated with increased mortality and poor clinical outcomes among people living with HIV/AIDS; however, the prevalence of malnutrition and food insecurity among people living with HIV/AIDS in Senegal, West Africa is unknown. The objective of this study was to determine the prevalence and severity of food insecurity and malnutrition among HIV-infected adults in Senegal, and to identify associations between food insecurity, malnutrition, and HIV outcomes. We conducted a cross-sectional study at outpatient clinics in Dakar and Ziguinchor, Senegal. Data were collected using participant interviews, anthropometry, the Household Food Insecurity Access Scale, the Individual Dietary Diversity Scale, and chart review. One hundred and nine HIV-1 and/or HIV-2 participants were enrolled. The prevalence of food insecurity was 84.6% in Dakar and 89.5% in Ziguinchor. The prevalence of severe food insecurity was 59.6% in Dakar and 75.4% in Ziguinchor. The prevalence of malnutrition (BMI insecurity was associated with missing clinic appointments (p = 0.01) and not taking antiretroviral therapy due to hunger (p = 0.02). Malnutrition was associated with lower CD4 cell counts (p = 0.01). Severe food insecurity and malnutrition are highly prevalent among HIV-infected adults in both Dakar and Ziguinchor, and are associated with poor HIV outcomes. Our findings warrant further studies to determine the root causes of malnutrition and food insecurity in Senegal, and the short- and long-term impacts of malnutrition and food insecurity on HIV care. Urgent interventions are needed to address the unacceptably high rates of malnutrition and food insecurity in this population.

    Full Text Available Background:   This study was to evaluate the prevalence of CTX-Mand TEM type ESBLs-producing K. pneumoniae and determination of MDR, XDR, and PDR phenotypes of these isolates as well as find out the genetic relationship and molecular typing of these isolates using phenotypic and genotypic methods.Methods:   Non-repetitive 96 K. pneumonia isolates were isolated from hospitalized patients in Al-Zahra hospital of Isfahan, Iran. The antibiotic susceptibility test was assessed for 20 antibiotics using Kirby-Bauer disk diffusion method. The frequency of ESBL-producing isolates was determined by phenotypic confirmatory test. All ESBLs-producing isolates were assessed for blaTEM and blaCTX-M genes using PCR method. Molecular typing was performed by enterobacterial repetitive intergenic consensus sequence-based PCR (ERIC-PCR.Results:  Among 96 isolates, 58 isolates (60.4% were ESBL-producers. In this study, 85.7% and 30.3% of ESBL-producing isolates showed MDR and XDR phenotypes, respectively. No PDR isolate was found. PCR amplification on ESBL-producing isolates showed that 47 (81% isolates were carried blaTEM gene, while blaCTX-M was detected in all isolates (100%. ERIC-PCR typing was characterized the high genetic similarity among ESBL-producing K. pneumonia isolates and revealed 32 band pattern for the isolates. Conclusion:  This study showed high prevalence of important ESBL genes (blaCTX-M and blaTEM genes among the K. pneumoniae isolated from in-patients. Constant following of ESBLs, also identification of their types, in bacteria isolated from hospitalized patients has an important clinical impact. It can provide valuable information for the choice of appropriate antibacterial therapy and decrease of antibiotic resistance.

    2017-10-01

    Echocardiography has been proposed as a method to screen children for rheumatic heart disease. The World Heart Federation has established guidelines for echocardiographic screening. In this study, we describe a rapid echocardiogram screening protocol according to the World Heart Federation guidelines in Samoa, endemic for rheumatic heart disease. We performed echocardiogram screening in schoolchildren in Samoa between 2013 and 2015. A brief screening echocardiogram was performed on all students. Children with predefined criteria suspicious for rheumatic hear diseases were referred for a more comprehensive echocardiogram. Complete echocardiograms were classified according to the World Heart Federation guidelines and severity of valve disease. Echocardiographic screening was performed on 11,434 children, with a mean age of 10.2 years; 51% of them were females. A total of 558 (4.8%) children underwent comprehensive echocardiography, including 49 students who were randomly selected as controls. Definite rheumatic heart disease was observed in 115 students (10.0 per 1000): 92 students were classified as borderline (8.0 per 1000) and 23 with CHD. Advanced disease was identified in 50 students (4.4 per 1000): 15 with severe mitral regurgitation, five with severe aortic regurgitation, 11 with mitral stenoses, and 19 with mitral and aortic valve disease. We successfully applied a rapid echocardiographic screening protocol to a large number of students over a short time period - 28 days of screening over a 3-year time period - to identify a high prevalence of rheumatic heart disease. We also reported a significantly higher rate of advanced disease compared with previously published echocardiographic screening programmes.

    This study aimed at investigating the presence of antibiotic-resistant Escherichia coli in river bed sediments of the Apies River, Gauteng, South Africa, in order to better inform health management decisions designed to protect users of the river. Overall, 180 water and sediment samples were collected at 10 sites along the Apies River from January to February 2014. E. coli was enumerated using the Colilert® 18/Quanti-Tray® 2000 (IDEXX). Isolates were purified by streaking on eosin methylene blue agar followed by the indole test. Pure E. coli isolates were tested for resistance to nine antibiotics by the Kirby-Bauer disc diffusion method. Over 98% of the isolates were resistant to at least one of the antibiotics tested. The highest resistance was observed against nitrofurantoin (sediments) and ampicillin (water). Over 80% of all resistant isolates showed multiple antibiotic resistance (resistance to ≥3 antibiotics). The abundance of E. coli in the sediments not only adds to the evidence that sediments are a reservoir for bacteria and possibly other pathogens including antibiotic-resistant bacteria but also suggests that antibiotic-resistant genes could be transferred to pathogens due to the high prevalence of multiple-antibiotic-resistant (MAR) strains of E. coli observed in the sediment. Using untreated water from the Apies River following resuspension for drinking and other household purposes could pose serious health risks for users. Our results suggest that river bed sediments could serve as reservoirs for MAR bacteria including pathogens under different climatic conditions and their analysis could provide information of public health concerns.

    To describe the relation between magnitude of anisometropia and interocular acuity difference (IAD), stereoacuity (SA), and the presence of amblyopia in school-aged members of a Native American tribe with a high prevalence of astigmatism. Refractive error (cycloplegic autorefraction confirmed by retinoscopy), best corrected monocular visual acuity (VA; Early Treatment Diabetic Retinopathy Study logMAR charts), and best corrected SA (Randot Preschool Stereoacuity Test) were measured in 4- to 13-year-old Tohono O'odham children (N = 972). Anisometropia was calculated in clinical notation (spherical equivalent and cylinder) and in two forms of vector notation that take into account interocular differences in both axis and cylinder magnitude. Astigmatism >or= 1.00 D was present in one or both eyes of 415 children (42.7%). Significant increases in IAD and presence of amblyopia (IAD >or= 2 logMAR lines) occurred, with >or=1 D of hyperopic anisometropia and >or=2 to 3 D of cylinder anisometropia. Significant decreases in SA occurred with >or=0.5 D of hyperopic, myopic, or cylinder anisometropia. Results for vector notation depended on the analysis used, but also showed disruption of SA at lower values of anisometropia than were associated with increases in IAD and presence of amblyopia. Best corrected IAD and presence of amblyopia are related to amount and type of refractive error difference (hyperopic, myopic, or cylindrical) between eyes. Disruption of best corrected random dot SA occurs with smaller interocular differences than those producing an increase in IAD, suggesting that the development of SA is particularly dependent on similarity of the refractive error between eyes.

    A National Health and Nutrition Survey (ENSANUT) conducted in Mexico in 1999 identified a high prevalence of inadequate mineral intakes in the population by using 24-h recall questionnaires. However, the 1999 survey did not adjust for within-person variance. The 2012 ENSANUT implemented a more up-to-date 24-h recall methodology to estimate usual intake distributions and prevalence of inadequate intakes. We examined the distribution of usual intakes and prevalences of inadequate intakes of calcium, iron, magnesium, and zinc in the Mexican population in groups defined according to sex, rural or urban area, geographic region of residence, and socioeconomic status (SES). We used dietary intake data obtained through the 24-h recall automated multiple-pass method for 10,886 subjects as part of ENSANUT 2012. A second measurement on a nonconsecutive day was obtained for 9% of the sample. Distributions of usual intakes of the 4 minerals were obtained by using the Iowa State University method, and the prevalence of inadequacy was estimated by using the Institute of Medicine's Estimated Average Requirement cutoff. Calcium inadequacy was 25.6% in children aged 1-4 y and 54.5-88.1% in subjects >5 y old. More than 45% of subjects >5 y old had an inadequate intake of iron. Less than 5% of children aged 12 y had inadequate intakes of magnesium, whereas zinc inadequacy ranged from <10% in children aged <12 y to 21.6% in men aged ≥20 y. Few differences were found between rural and urban areas, regions, and tertiles of SES. Intakes of calcium, iron, magnesium, and zinc are inadequate in the Mexican population, especially among adolescents and adults. These results suggest a public health concern that must be addressed. © 2016 American Society for Nutrition.

    2018-04-03

    Squalene-based adjuvants have been included in influenza vaccines since 1997. Despite several advantages of adjuvanted seasonal and pandemic influenza vaccines, laypeople's perception of such formulations may be hesitant or even negative under certain circumstances. Moreover, in Italian, the term "squalene" has the same root as such common words as "shark" (squalo), "squalid" and "squalidness" that tend to have negative connotations. This study aimed to quantitatively and qualitatively analyze a representative sample of Italian web pages mentioning squalene-based adjuvants used in influenza vaccines. Every effort was made to limit the subjectivity of judgments. Eighty-four unique web pages were assessed. A high prevalence (47.6%) of pages with negative or ambiguous attitudes toward squalene-based adjuvants was established. Compared with web pages reporting balanced information on squalene-based adjuvants, those categorized as negative/ambiguous had significantly lower odds of belonging to a professional institution [adjusted odds ratio (aOR) = 0.12, p = .004], and significantly higher odds of containing pictures (aOR = 1.91, p = .034) and being more readable (aOR = 1.34, p = .006). Some differences in wording between positive/neutral and negative/ambiguous web pages were also observed. The most common scientifically unsound claims concerned safety issues and, in particular, claims linking squalene-based adjuvants to the Gulf War Syndrome and autoimmune disorders. Italian users searching the web for information on vaccine adjuvants have a high likelihood of finding unbalanced and misleading material. Information provided by institutional websites should be not only evidence-based but also carefully targeted towards laypeople. Conversely, authors writing for non-institutional websites should avoid sensationalism and provide their readers with more balanced information.

  1. High prevalence of cannabis use among Aka foragers of the Congo Basin and its possible relationship to helminthiasis.

    Little is known about cannabis use in hunter-gatherers. Therefore, we investigated cannabis use in the Aka, a population of foragers of the Congo Basin. Because cannabis contains anthelminthic compounds, and the Aka have a high prevalence of helminthiasis, we also tested the hypothesis that cannabis use might be an unconscious form of self-medication against helminths. We collected self- and peer-reports of cannabis use from all adult Aka in the Lobaye district of the Central African Republic (n = 379). Because female cannabis use was low, we restricted sample collection to men. Using an immunoassay for Δ9-tetrahydrocannabinol-11-oic acid (THCA), a urinary biomarker of recent cannabis consumption, we validated cannabis use in men currently residing in camps near a logging road (n = 62). We also collected stool samples to assay worm burden. A longitudinal reinfection study was conducted among a subsample of the male participants (n = 23) who had been treated with a commercial anthelmintic 1 year ago. The prevalence of self- and peer-reported cannabis use was 70.9% among men and 6.1% among women, for a total prevalence of 38.6%. Using a 50 ng/ml threshold for THCA, 67.7% of men used cannabis. Cannabis users were significantly younger and had less material wealth than the non-cannabis users. There were significant negative associations between THCA levels and worm burden, and reinfection with helminths 1 year after treatment with a commercial anthelmintic. The prevalence of cannabis use among adult Aka men was high when compared to most global populations. THCA levels were negatively correlated with parasite infection and reinfection, supporting the self-medication hypothesis. © 2015 Wiley Periodicals, Inc.

    Hispanics are the fastest growing segment of the U.S. population and have a higher prevalence of cardiometabolic risk factors as compared with non-Hispanic whites. Further data suggests that Hispanics have undiagnosed complications of metabolic syndrome, namely diabetes mellitus, at an earlier age. We sought to better understand the epidemiology of metabolic syndrome in Hispanic women using data from a large, community-based health screening program. Using data from the Sister to Sister: The Women's Heart Health Foundation community health fairs from 2008 to 2009 held in 17 U.S. cities, we sought to characterize how cardiometabolic risk profiles vary across age for women by race and ethnicity. Metabolic syndrome was defined using the updated National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guidelines, which included three or more of the following: Waist circumference ≥35 inches, triglycerides ≥150 mg/dL, high-density lipoprotein (HDL) <50 mg/dL, systolic blood pressure ≥130 mmHg or diastolic blood pressure ≥85 mmHg, or a fasting glucose ≥100 mg/dL. A total of 6843 community women were included in the analyses. Metabolic syndrome had a prevalence of 35%. The risk-adjusted odds ratio for metabolic syndrome in Hispanic women versus white women was 1.7 (95% confidence interval, 1.4, 2.0). Dyslipidemia was the strongest predictor of metabolic syndrome among Hispanic women. This disparity appeared most pronounced for younger women. Additional predictors of metabolic syndrome included black race, increasing age, and smoking. In a large, nationally representative sample of women, we found that metabolic syndrome was highly prevalent among young Hispanic women. Efforts specifically targeted to identifying these high-risk women are necessary to prevent the cardiovascular morbidity and mortality associated with metabolic syndrome.

    Hypertension and other chronic disease risks are common among Aboriginal and Torres Strait Islander adults but there is little evidence regarding the epidemiology of these risk factors during adolescence. This study examines the prevalence of pre-hypertension, hypertension and other cardiovascular risk factors in Aboriginal and Torres Strait Islander people aged 15-24 years living in remote Indigenous communities in north Queensland. In so doing, it aims to better inform the approach to cardiovascular disease in this population. This is a descriptive study that retrospectively examines health service data from a program of community screening, the Young Persons Check (YPC). Participants were 1,883 Aboriginal and Torres Strait Islander people aged 15-24 years who attended for a YPC in 11 remote communities in north Queensland between March 2009 and April 2011. Overall, the prevalence of pre-hypertension was 34.0%; stage I hypertension was 17.7% and stage II hypertension was 3.3%. The prevalence of elevated waist circumference was 47.6%, overweight or obesity 45.9%, elevated triglycerides 18.3%, decreased HDL 54.8% and proteinuria 24.3%. The prevalence of hypertension (stage I or II) among Torres Strait Islander males was 34.1%, Aboriginal males 26.9%, Torres Strait Islander females 12.6% and Aboriginal females 13.0%. Hypertension was associated with sex (males) (OR= 4.37, p<0.000), overweight (OR=2.46, p<0.000), obesity (OR=4.59, p<0.000) and elevated triglycerides (OR=2.38, p<0.000). Pre-hypertension, hypertension and other cardiovascular risk in this population is highly prevalent. Hypertension was particularly prevalent among male participants. The results reiterate the importance of early life experience in cardiovascular disease prevention. © 2015 The Authors.

    Sex differentials in the uptake of HIV testing have been reported in a range of settings, however, men's and women's testing patterns are not consistent across these settings, suggesting the need to set sex differentials against gender norms in patient testing behaviour and provider practices. A community-based, cross-sectional survey among 347 people living with HIV in three HIV high prevalence districts of India examined reasons for undergoing an HIV test, location of testing and conditions under which individuals were tested. HIV testing was almost always provider-initiated for men. Men were more likely to be advised to test by a private practitioner and to test in the private sector. Women were more likely to be advised to test by a family member, and to test in the public sector. Men were more likely to receive pre-test information than women, when tested in the private sector. Men were also more likely to receive direct disclosure of their HIV positive status by a health provider, regardless of the sector in which they tested. More women than men were repeatedly tested for HIV, regardless of sector. These sex differentials in the uptake and process of HIV testing are partially explained through differences in public and private sector testing practices. However, they also reflect women's lack of awareness and agency in HIV care seeking and differential treatment by providers. Examining gender dynamics that underpin sex differentials in HIV testing patterns and practices is essential for a realistic assessment of the challenges and implications of scaling-up HIV testing and mainstreaming gender in HIV/AIDS programmes.

  5. Global warming will reshuffle the areas of high prevalence and richness of three genera of avian blood parasites.

    The importance of parasitism for host populations depends on local parasite richness and prevalence: usually host individuals face higher infection risk in areas where parasites are most diverse, and host dispersal to or from these areas may have fitness consequences. Knowing how parasites are and will be distributed in space and time (in a context of global change) is thus crucial from both an ecological and a biological conservation perspective. Nevertheless, most research articles focus just on elaborating models of parasite distribution instead of parasite diversity. We produced distribution models of the areas where haemosporidian parasites are currently highly diverse (both at community and at within-host levels) and prevalent among Iberian populations of a model passerine host: the blackcap Sylvia atricapilla; and how these areas are expected to vary according to three scenarios of climate change. On the basis of these models, we analysed whether variation among populations in parasite richness or prevalence are expected to remain the same or change in the future, thereby reshuffling the geographic mosaic of host-parasite interactions as we observe it today. Our models predict a rearrangement of areas of high prevalence and richness of parasites in the future, with Haemoproteus and Leucocytozoon parasites (today the most diverse genera in blackcaps) losing areas of high diversity and Plasmodium parasites (the most virulent ones) gaining them. Likewise, the prevalence of multiple infections and parasite infracommunity richness would be reduced. Importantly, differences among populations in the prevalence and richness of parasites are expected to decrease in the future, creating a more homogeneous parasitic landscape. This predicts an altered geographic mosaic of host-parasite relationships, which will modify the interaction arena in which parasite virulence evolves. © 2014 John Wiley & Sons Ltd.

  6. Decreasing prevalence of the full metabolic syndrome but a persistently high prevalence of dyslipidemia among adult Arabs.

    Nasser M Al-Daghri

    Full Text Available A decade has passed since metabolic syndrome (MetS was documented to be highly prevalent in the kingdom of Saudi Arabia. No follow-up epidemiologic study was done. This study aims to fill this gap. In this cross-sectional, observational study, a total of 2850 randomly selected Saudi adults aged 18-55 years were recruited. Subjects' information was generated from a database of more than 10,000 Saudi citizens from the existing Biomarkers Screening in Riyadh Program (RIYADH Cohort, Saudi Arabia. Anthropometrics included body mass index (BMI, blood pressure, as well as waist and hip circumferences. Fasting blood glucose and lipid profile were determined using routine laboratory procedures. The definition of ATP-III (NHANES III was used for the diagnosis of the full MetS. The overall prevalence of complete MetS was 35.3% [Confidence-Interval (CI 33.5-37.01]. Age-adjusted prevalence according to the European standard population is 37.0%. Low HDL-cholesterol was the most prevalent of all MetS risk factors, affecting 88.6% (CI 87.5-89.7 and hypertriglyceridemia the second most prevalent, affecting 34% (CI 32.3-35.7 of the subjects. The prevalence of the full MetS decreased from previous estimates but remains high, while dyslipidemia remains extremely high, affecting almost 90% of middle-aged Arabs. Screening for dyslipidemia among Saudi adults is warranted, especially among those most at risk. Scientific inquiry into the molecular causes of these manifestations should be pursued as a first step in the discovery of etiologic therapies.

  7. Hummingbirds rely on both paracellular and carrier-mediated intestinal glucose absorption to fuel high metabolism

    McWhorter, Todd J; Bakken, Bradley Hartman; Karasov, William H; del Rio, Carlos Martínez

    2005-01-01

    Twenty years ago, the highest active glucose transport rate and lowest passive glucose permeability in vertebrates were reported in Rufous and Anna's hummingbirds (Selasphorus rufus, Calypte anna). These first measurements of intestinal nutrient absorption in nectarivores provided an unprecedented physiological foundation for understanding their foraging ecology. They showed that physiological processes are determinants of feeding behaviour. The conclusion that active, mediated transport accounts for essentially all glucose absorption in hummingbirds influenced two decades of subsequent research on the digestive physiology and nutritional ecology of nectarivores. Here, we report new findings demonstrating that the passive permeability of hummingbird intestines to glucose is much higher than previously reported, suggesting that not all sugar uptake is mediated. Even while possessing the highest active glucose transport rates measured in vertebrates, hummingbirds must rely partially on passive non-mediated intestinal nutrient absorption to meet their high mass-specific metabolic demands.

  8. Episodic Memory Retrieval Functionally Relies on Very Rapid Reactivation of Sensory Information.

    Waldhauser, Gerd T; Braun, Verena; Hanslmayr, Simon

    2016-01-06

    Episodic memory retrieval is assumed to rely on the rapid reactivation of sensory information that was present during encoding, a process termed "ecphory." We investigated the functional relevance of this scarcely understood process in two experiments in human participants. We presented stimuli to the left or right of fixation at encoding, followed by an episodic memory test with centrally presented retrieval cues. This allowed us to track the reactivation of lateralized sensory memory traces during retrieval. Successful episodic retrieval led to a very early (∼100-200 ms) reactivation of lateralized alpha/beta (10-25 Hz) electroencephalographic (EEG) power decreases in the visual cortex contralateral to the visual field at encoding. Applying rhythmic transcranial magnetic stimulation to interfere with early retrieval processing in the visual cortex led to decreased episodic memory performance specifically for items encoded in the visual field contralateral to the site of stimulation. These results demonstrate, for the first time, that episodic memory functionally relies on very rapid reactivation of sensory information. Remembering personal experiences requires a "mental time travel" to revisit sensory information perceived in the past. This process is typically described as a controlled, relatively slow process. However, by using electroencephalography to measure neural activity with a high time resolution, we show that such episodic retrieval entails a very rapid reactivation of sensory brain areas. Using transcranial magnetic stimulation to alter brain function during retrieval revealed that this early sensory reactivation is causally relevant for conscious remembering. These results give first neural evidence for a functional, preconscious component of episodic remembering. This provides new insight into the nature of human memory and may help in the understanding of psychiatric conditions that involve the automatic intrusion of unwanted memories. Copyright

  9. Cochlear implant users rely on tempo rather than on pitch information during perception of musical emotion.

    2015-09-01

    The purpose of this study was to investigate the extent to which cochlear implant (CI) users rely on tempo and mode in perception of musical emotion when compared with normal hearing (NH) individuals. A test battery of novel four-bar melodies was created and adapted to four permutations with alterations of tonality (major vs. minor) and tempo (presto vs. largo), resulting in non-ambiguous (major key/fast tempo and minor key/slow tempo) and ambiguous (major key/slow tempo, and minor key/fast tempo) musical stimuli. Both CI and NH participants listened to each clip and provided emotional ratings on a Likert scale of +5 (happy) to -5 (sad). A three-way ANOVA demonstrated an overall effect for tempo in both groups, and an overall effect for mode in the NH group. The CI group rated stimuli of the same tempo similarly, regardless of changes in mode, whereas the NH group did not. A subgroup analysis indicated the same effects in both musician and non-musician CI users and NH listeners. The results suggest that the CI group relied more heavily on tempo than mode in making musical emotion decisions. The subgroup analysis further suggests that level of musical training did not significantly impact this finding. CI users weigh temporal cues more heavily than pitch cues in inferring musical emotion. These findings highlight the significant disadvantage of CI users in comparison with NH listeners for music perception, particularly during recognition of musical emotion, a critically important feature of music.

  10. Access to Grafts in a Liver Transplant Center: Does It Rely on the Severity of the Waiting List Population?

    2018-03-01

    The number of transplants performed relies, partially, on recipients' variables on the waiting list. The goal of this study was to compare recipients from a high-volume liver center in Argentina with the rest of the country. This study was a retrospective analysis of liver transplant recipients nationally between January 2013 and April 2017. It involved extracting data from the open database CRESI-SINTRA (the Argentinian database of the National Procurement Organization, an equivalent to the United Network for Organ Sharing); expressing results by percentages, medians, and interquartile ranges (IQRs); and comparing the national population with the population transplanted at Hospital El Cruce (HEC). The Mann-Whitney U test was used for analysis. Nationally, 1434 liver transplants were performed. A total of 177 (12.34%) were emergency status; 811 (56.6%) were by the Model for End-Stage Liver Disease (MELD) (n = 759)/PELD (Pediatric End-Stage Liver Disease) (n = 52), with a median graft assignment position of 5 (IQR, 3-10) in 57.2 days (IQR, 11-217). Median MELD access was 29 points (IQR, 24-33). A total of 446 (31.1%) had MELD exceptions; 249 (55.8%) of these were due to Milan hepatocellular carcinoma. At the HEC, 167 liver transplantations were performed; 26 (15.6%) were emergency status and 97 (58.1%) by MELD (none PELD). Their median graft assignment position was 4 (IQR, 4-16) in 19.1 days (IQR, 4-90); median MELD access was 28 points (IQR, 24-31). Forty-five patients (26.9%) had MELD exceptions; 31 (68.9%) were due to hepatocellular carcinoma. Our center has a larger proportion of recipients transplanted by emergency status and MELD, similar MELD access, and less waiting list time, reflecting our wide policy of liver graft acceptance.

  13. Defining the buffering process by a triprotic acid without relying on Stewart-electroneutrality considerations.

    Nguyen, Minhtri K; Kao, Liyo; Kurtz, Ira

    2011-08-17

    Upon the addition of protons to an aqueous solution, a component of the H+ load will be bound i.e. buffered. In an aqueous solution containing a triprotic acid, H+ can be bound to three different states of the acid as well as to OH- ions that are derived from the auto-ionization of H2O. In quantifying the buffering process of a triprotic acid, one must define the partitioning of H+ among the three states of the acid and also the OH- ions in solution in order to predict the equilibrium pH value. However, previous quantitative approaches that model triprotic acid titration behaviour and used to predict the equilibrium pH rely on the mathematical convenience of electroneutrality/charge balance considerations. This fact has caused confusion in the literature, and has led to the assumption that charge balance/electroneutrality is a causal factor in modulating proton buffering (Stewart formulation). However, as we have previously shown, although charge balance can be used mathematically as a convenient tool in deriving various formulae, electroneutrality per se is not a fundamental physicochemical parameter that is mechanistically involved in the underlying buffering and proton transfer reactions. The lack of distinction between a mathematical tool, and a fundamental physicochemical parameter is in part a reason for the current debate regarding the Stewart formulation of acid-base analysis. We therefore posed the following question: Is it possible to generate an equation that defines and predicts the buffering of a triprotic acid that is based only on H+ partitioning without incorporating electroneutrality in the derivation? Towards this goal, we derived our new equation utilizing: 1) partitioning of H+ buffering; 2) conservation of mass; and 3) acid-base equilibria. In validating this model, we compared the predicted equilibrium pH with the measured pH of an aqueous solution consisting of Na2HPO4 to which HCl was added. The measured pH values were in excellent agreement

However, as we have previously shown, although charge balance can be used mathematically as a convenient tool in deriving various formulae, electroneutrality per se is not a fundamental physicochemical parameter that is mechanistically involved in the underlying buffering and proton transfer reactions. The lack of distinction between a mathematical tool, and a fundamental physicochemical parameter is in part a reason for the current debate regarding the Stewart formulation of acid-base analysis. We therefore posed the following question: Is it possible to generate an equation that defines and predicts the buffering of a triprotic acid that is based only on H+ partitioning without incorporating electroneutrality in the derivation? Towards this goal, we derived our new equation utilizing: 1) partitioning of H+ buffering; 2) conservation of mass; and 3) acid-base equilibria. In validating this model, we compared the predicted equilibrium pH with the measured pH of an aqueous solution consisting of Na2HPO4 to which HCl was added. The measured pH values were in excellent agreement

    Alyousefi, Naelah A.; Mahdy, Mohammed A. K.; Mahmud, Rohela; Lim, Yvonne A. L.

    2011-01-01

    Background Intestinal protozoan diseases in Yemen are a significant health problem with prevalence ranging from 18% to 27%. The present study is a cross-sectional study aimed at determining the factors associated with the high prevalence of intestinal protozoan infections among patients seeking health care in Sana'a City, the capital of Yemen. Methodology/Principal Findings Stool samples were collected from 503 patients aged between 1 and 80 years old; 219 were males and 284 females. Biodata were collected via pretested standard questionnaire. Faecal samples were processed and examined for (oo)cysts or ova using a wet mount preparation after formal-ether concentration technique. Cryptosporidium oocysts were detected using the Ziehl-Neelsen staining technique. The overall prevalence of intestinal protozoan infections was 30.9%. Infection rates of Giardia duodenalis, Entamoeba histolytica/dispar and Cryptosporidium were 17.7%, 17.1% and 1%, respectively. Other parasites detected included Ascaris lumbricoides (2.4%), Schistosoma mansoni (0.3%), Hymenolepis nana (1.4%) and Enterobius vermicularis (0.4%). Multivariate analysis using forward stepwise logistic regression based on intestinal protozoan infections showed that contact with animals (OR = 1.748, 95% CI = 1.168–2.617) and taking bath less than twice a week (OR = 1.820, 95% CI = 1.192–2.779) were significant risk factors of protozoan infections. Conclusions/Significance This present study indicated that intestinal protozoan infections are still a public health problem in Yemen, with Giardia and Entamoeba infections being most common. Statistical analysis indicated that low personal hygiene and contact with animals were important predictors for intestinal protozoan infections. As highlighted in this study, in order to effectively reduce these infections, a multi-sectoral effort is needed. Preventive measures should include good hygienic practices, good animal husbandry practices, heightened

  1. Frugivorous bats maintain functional habitat connectivity in agricultural landscapes but rely strongly on natural forest fragments.

    Ripperger, Simon P; Kalko, Elisabeth K V; Rodríguez-Herrera, Bernal; Mayer, Frieder; Tschapka, Marco

    2015-01-01

    Anthropogenic changes in land use threaten biodiversity and ecosystem functioning by the conversion of natural habitat into agricultural mosaic landscapes, often with drastic consequences for the associated fauna. The first step in the development of efficient conservation plans is to understand movement of animals through complex habitat mosaics. Therefore, we studied ranging behavior and habitat use in Dermanura watsoni (Phyllostomidae), a frugivorous bat species that is a valuable seed disperser in degraded ecosystems. Radio-tracking of sixteen bats showed that the animals strongly rely on natural forest. Day roosts were exclusively located within mature forest fragments. Selection ratios showed that the bats foraged selectively within the available habitat and positively selected natural forest. However, larger daily ranges were associated with higher use of degraded habitats. Home range geometry and composition of focal foraging areas indicated that wider ranging bats performed directional foraging bouts from natural to degraded forest sites traversing the matrix over distances of up to three hundred meters. This behavior demonstrates the potential of frugivorous bats to functionally connect fragmented areas by providing ecosystem services between natural and degraded sites, and highlights the need for conservation of natural habitat patches within agricultural landscapes that meet the roosting requirements of bats.

  2. Efficient secretion of small proteins in mammalian cells relies on Sec62-dependent posttranslational translocation

    Lakkaraju, Asvin K. K.; Thankappan, Ratheeshkumar; Mary, Camille; Garrison, Jennifer L.; Taunton, Jack; Strub, Katharina

    2012-01-01

    Mammalian cells secrete a large number of small proteins, but their mode of translocation into the endoplasmic reticulum is not fully understood. Cotranslational translocation was expected to be inefficient due to the small time window for signal sequence recognition by the signal recognition particle (SRP). Impairing the SRP pathway and reducing cellular levels of the translocon component Sec62 by RNA interference, we found an alternate, Sec62-dependent translocation path in mammalian cells required for the efficient translocation of small proteins with N-terminal signal sequences. The Sec62-dependent translocation occurs posttranslationally via the Sec61 translocon and requires ATP. We classified preproteins into three groups: 1) those that comprise ≤100 amino acids are strongly dependent on Sec62 for efficient translocation; 2) those in the size range of 120–160 amino acids use the SRP pathway, albeit inefficiently, and therefore rely on Sec62 for efficient translocation; and 3) those larger than 160 amino acids depend on the SRP pathway to preserve a transient translocation competence independent of Sec62. Thus, unlike in yeast, the Sec62-dependent translocation pathway in mammalian cells serves mainly as a fail-safe mechanism to ensure efficient secretion of small proteins and provides cells with an opportunity to regulate secretion of small proteins independent of the SRP pathway.

  3. Regulatory theory: commercially sustainable markets rely upon satisfying the public interest in obtaining credible goods.

    Warren-Jones, Amanda

    2017-10-01

    Regulatory theory is premised on the failure of markets, prompting a focus on regulators and industry from economic perspectives. This article argues that overlooking the public interest in the sustainability of commercial markets risks markets failing completely. This point is exemplified through health care markets - meeting an essential need - and focuses upon innovative medicines as the most desired products in that market. If this seemingly invulnerable market risks failure, there is a pressing need to consider the public interest in sustainable markets within regulatory literature and practice. Innovative medicines are credence goods, meaning that the sustainability of the market fundamentally relies upon the public trusting regulators to vouch for product quality. Yet, quality is being eroded by patent bodies focused on economic benefits from market growth, rather than ensuring innovatory value. Remunerative bodies are not funding medicines relative to market value, and market authorisation bodies are not vouching for robust safety standards or confining market entry to products for 'unmet medical need'. Arguably, this failure to assure quality heightens the risk of the market failing where it cannot be substituted by the reputation or credibility of providers of goods and/or information such as health care professionals/institutions, patient groups or industry.

  4. Quality of record linkage in a highly automated cancer registry that relies on encrypted identity data

    Schmidtmann, Irene

    2016-06-01

    Full Text Available Objectives: In the absence of unique ID numbers, cancer and other registries in Germany and elsewhere rely on identity data to link records pertaining to the same patient. These data are often encrypted to ensure privacy. Some record linkage errors unavoidably occur. These errors were quantified for the cancer registry of North Rhine Westphalia which uses encrypted identity data. Methods: A sample of records was drawn from the registry, record linkage information was included. In parallel, plain text data for these records were retrieved to generate a gold standard. Record linkage error frequencies in the cancer registry were determined by comparison of the results of the routine linkage with the gold standard. Error rates were projected to larger registries.Results: In the sample studied, the homonym error rate was 0.015%; the synonym error rate was 0.2%. The F-measure was 0.9921. Projection to larger databases indicated that for a realistic development the homonym error rate will be around 1%, the synonym error rate around 2%.Conclusion: Observed error rates are low. This shows that effective methods to standardize and improve the quality of the input data have been implemented. This is crucial to keep error rates low when the registry’s database grows. The planned inclusion of unique health insurance numbers is likely to further improve record linkage quality. Cancer registration entirely based on electronic notification of records can process large amounts of data with high quality of record linkage.

  5. Pneumococcal Competence Coordination Relies on a Cell-Contact Sensing Mechanism.

    Marc Prudhomme

    2016-06-01

    Full Text Available Bacteria have evolved various inducible genetic programs to face many types of stress that challenge their growth and survival. Competence is one such program. It enables genetic transformation, a major horizontal gene transfer process. Competence development in liquid cultures of Streptococcus pneumoniae is synchronized within the whole cell population. This collective behavior is known to depend on an exported signaling Competence Stimulating Peptide (CSP, whose action generates a positive feedback loop. However, it is unclear how this CSP-dependent population switch is coordinated. By monitoring spontaneous competence development in real time during growth of four distinct pneumococcal lineages, we have found that competence shift in the population relies on a self-activated cell fraction that arises via a growth time-dependent mechanism. We demonstrate that CSP remains bound to cells during this event, and conclude that the rate of competence development corresponds to the propagation of competence by contact between activated and quiescent cells. We validated this two-step cell-contact sensing mechanism by measuring competence development during co-cultivation of strains with altered capacity to produce or respond to CSP. Finally, we found that the membrane protein ComD retains the CSP, limiting its free diffusion in the medium. We propose that competence initiator cells originate stochastically in response to stress, to form a distinct subpopulation that then transmits the CSP by cell-cell contact.

    2017-08-01

    Introduction Examining various problems in the aftermath of disasters is very important to the disaster victims. Managing and coordinating food supply and its distribution among the victims is one of the most important problems after an earthquake. Therefore, the purpose of this study was to recognize problems and experiences in the field of nutritional aiding during an earthquake. This qualitative study was of phenomenological type. Using the purposive sampling method, 10 people who had experienced nutritional aiding during the Bam Earthquake (Iran; 2003) were interviewed. Colaizzi's method of analysis was used to analyze interview data. The findings of this study identified four main categories and 19 sub-categories concerning challenges in the nutritional aiding during the Bam Earthquake. The main topics included managerial, aiding, infrastructural, and administrative problems. The major problems in nutritional aiding include lack of prediction and development of a specific program of suitable nutritional pattern and nutritional assessment of the victims in critical conditions. Forming specialized teams, educating team members about nutrition, and making use of experts' knowledge are the most important steps to resolve these problems in the critical conditions; these measures are the duties of the relevant authorities.

  8. The Low Pitch of High-Frequency Complex Tones Relies on Temporal Fine Structure Information

    Santurette, Sébastien; Dau, Torsten

    2010-01-01

    High-frequency complex tones containing only unresolved harmonic components with a frequency spacing Δf usually evoke a low pitch equal to Δf. However, for inharmonic components, the low pitch is often found to deviate slightly from Δf. Whether this pitch shift relies exclusively on temporal fine...... structure (TFS) cues has been a matter of debate. It is also controversial up to which frequency TFS information remains available, and to what extent envelope cues become dominant as frequency increases. Using a pitch-matching paradigm, this study investigated whether the pitch of transposed tones.......5]. All stimuli were presented at 50 dB SPL in broadband pink-noise (13.5 dB/Hz at 1 kHz), and 40 matches per condition were obtained.

  9. Mouse V1 population correlates of visual detection rely on heterogeneity within neuronal response patterns

    Montijn, Jorrit S; Goltstein, Pieter M; Pennartz, Cyriel MA

    2015-01-01

    Previous studies have demonstrated the importance of the primary sensory cortex for the detection, discrimination, and awareness of visual stimuli, but it is unknown how neuronal populations in this area process detected and undetected stimuli differently. Critical differences may reside in the mean strength of responses to visual stimuli, as reflected in bulk signals detectable in functional magnetic resonance imaging, electro-encephalogram, or magnetoencephalography studies, or may be more subtly composed of differentiated activity of individual sensory neurons. Quantifying single-cell Ca2+ responses to visual stimuli recorded with in vivo two-photon imaging, we found that visual detection correlates more strongly with population response heterogeneity rather than overall response strength. Moreover, neuronal populations showed consistencies in activation patterns across temporally spaced trials in association with hit responses, but not during nondetections. Contrary to models relying on temporally stable networks or bulk signaling, these results suggest that detection depends on transient differentiation in neuronal activity within cortical populations.

  10. Unparalleled sample treatment throughput for proteomics workflows relying on ultrasonic energy.

    Jorge, Susana; Araújo, J E; Pimentel-Santos, F M; Branco, Jaime C; Santos, Hugo M; Lodeiro, Carlos; Capelo, J L

    2018-02-01

    We report on the new microplate horn ultrasonic device as a powerful tool to speed proteomics workflows with unparalleled throughput. 96 complex proteomes were digested at the same time in 4min. Variables such as ultrasonication time, ultrasonication amplitude, and protein to enzyme ratio were optimized. The "classic" method relying on overnight protein digestion (12h) and the sonoreactor-based method were also employed for comparative purposes. We found the protein digestion efficiency homogeneously distributed in the entire microplate horn surface using the following conditions: 4min sonication time and 25% amplitude. Using this approach, patients with lymphoma and myeloma were classified using principal component analysis and a 2D gel-mass spectrometry based approach. Furthermore, we demonstrate the excellent performance by using MALDI-mass spectrometry based profiling as a fast way to classify patients with rheumatoid arthritis, systemic lupus erythematosus, and ankylosing spondylitis. Finally, the speed and simplicity of this method were demonstrated by clustering 90 patients with knee osteoarthritis disease (30), with a prosthesis (30, control group) and healthy individuals (30) with no history of joint disease. Overall, the new approach allows profiling a disease in just one week while allows to match the minimalism rules as outlined by Halls. Copyright © 2017 Elsevier B.V. All rights reserved.

  11. Laser-induced breakdown spectroscopy and chemometrics for classification of toys relying on toxic elements

    Godoi, Quienly; Leme, Flavio O.; Trevizan, Lilian C.; Pereira Filho, Edenir R.; Rufini, Iolanda A.; Santos, Dario; Krug, Francisco J.

    2011-01-01

    Quality control of toys for avoiding children exposure to potentially toxic elements is of utmost relevance and it is a common requirement in national and/or international norms for health and safety reasons. Laser-induced breakdown spectroscopy (LIBS) was recently evaluated at authors' laboratory for direct analysis of plastic toys and one of the main difficulties for the determination of Cd, Cr and Pb was the variety of mixtures and types of polymers. As most norms rely on migration (lixiviation) protocols, chemometric classification models from LIBS spectra were tested for sampling toys that present potential risk of Cd, Cr and Pb contamination. The classification models were generated from the emission spectra of 51 polymeric toys and by using Partial Least Squares - Discriminant Analysis (PLS-DA), Soft Independent Modeling of Class Analogy (SIMCA) and K-Nearest Neighbor (KNN). The classification models and validations were carried out with 40 and 11 test samples, respectively. Best results were obtained when KNN was used, with corrected predictions varying from 95% for Cd to 100% for Cr and Pb.

  12. Learning Similar Actions by Reinforcement or Sensory-Prediction Errors Rely on Distinct Physiological Mechanisms.

    Uehara, Shintaro; Mawase, Firas; Celnik, Pablo

    2017-09-14

    Humans can acquire knowledge of new motor behavior via different forms of learning. The two forms most commonly studied have been the development of internal models based on sensory-prediction errors (error-based learning) and success-based feedback (reinforcement learning). Human behavioral studies suggest these are distinct learning processes, though the neurophysiological mechanisms that are involved have not been characterized. Here, we evaluated physiological markers from the cerebellum and the primary motor cortex (M1) using noninvasive brain stimulations while healthy participants trained finger-reaching tasks. We manipulated the extent to which subjects rely on error-based or reinforcement by providing either vector or binary feedback about task performance. Our results demonstrated a double dissociation where learning the task mainly via error-based mechanisms leads to cerebellar plasticity modifications but not long-term potentiation (LTP)-like plasticity changes in M1; while learning a similar action via reinforcement mechanisms elicited M1 LTP-like plasticity but not cerebellar plasticity changes. Our findings indicate that learning complex motor behavior is mediated by the interplay of different forms of learning, weighing distinct neural mechanisms in M1 and the cerebellum. Our study provides insights for designing effective interventions to enhance human motor learning. © The Author 2017. Published by Oxford University Press. All rights reserved.

  13. Palliative care in Argentina: perspectives from a country in crisis.

    De Simone, Gustavo G

    2003-01-01

    Argentina is a large South American country with a high prevalence of chronic disease-related mortality and a clear need for implementation of palliative care. Primary concerns related to palliative care are cultural, socio-economic and educational. Increasing poverty, patients and families receiving inadequate information about their diagnosis or prognosis, drug availability and costs, and insufficient knowledge by health care providers are obstacles to palliative care. Palliative care programs are developing throughout the country and methods by which they are meeting their needs are described. Several Argentinean palliative care initiatives are described and the role of the Pallium Latinomérica training program is discussed.

    2009-03-01

    Full Text Available Hypothyroidism is one of the most common endocrine diseases. The prevalence of hypothyroidism in adults is estimated to be 1–2% for overt hypothyroidism and 7–10% for subclinical hypothyroidism, especially in elder women. Considering high prevalence of hypothyroidism and negative consequences of nontreated hypothyroidism for health, we conducted the work which aim was the assessment of consumption of thyroid hormones in Russia in comparison with the countries of Europe. The aim of this analysis, in turn, is the approximate estimation of hypodiagnostics of hypothyroidism in our country.

  15. Call Home? Mobile Phones and Contacts with Mother in 24 Countries.

    Gubernskaya, Zoya; Treas, Judith

    2016-10-01

    This paper explores how the diffusion of mobile phones is associated with communication between adult children and their mothers. The paper analyzes 2001 International Social Survey Program (ISSP) data from 24 countries (N = 12,313) combined with the country-level data on the prevalence of mobile phones. Net of individual-level predictors and country wealth, adult children who resided in countries with high prevalence of mobile phones contacted their mothers more frequently. High prevalence of mobile phones was also associated with larger differences in maternal contact by gender and smaller differences by education. These findings suggest that any impact of new communication technology on intergenerational relations is complex. Although mobile phones point to higher levels of at-a-distance contact with mothers and narrower socio-economic disparities related to access and affordability of communication technology, they are also linked to wider contact disparities following gendered cultural expectations.

  16. Fruit production in three masting tree species does not rely on stored carbon reserves.

    Hoch, Günter; Siegwolf, Rolf T W; Keel, Sonja G; Körner, Christian; Han, Qingmin

    2013-03-01

    Fruiting is typically considered to massively burden the seasonal carbon budget of trees. The cost of reproduction has therefore been suggested as a proximate factor explaining observed mast-fruiting patterns. Here, we used a large-scale, continuous (13)C labeling of mature, deciduous trees in a temperate Swiss forest to investigate to what extent fruit formation in three species with masting reproduction behavior (Carpinus betulus, Fagus sylvatica, Quercus petraea) relies on the import of stored carbon reserves. Using a free-air CO2 enrichment system, we exposed trees to (13)C-depleted CO2 during 8 consecutive years. By the end of this experiment, carbon reserve pools had significantly lower δ(13)C values compared to control trees. δ(13)C analysis of new biomass during the first season after termination of the CO2 enrichment allowed us to distinguish the sources of built-in carbon (old carbon reserves vs. current assimilates). Flowers and expanding leaves carried a significant (13)C label from old carbon stores. In contrast, fruits and vegetative infructescence tissues were exclusively produced from current, unlabeled photoassimilates in all three species, including F. sylvatica, which had a strong masting season. Analyses of δ(13)C in purified starch from xylem of fruit-bearing shoots revealed a complete turn-over of starch during the season, likely due to its usage for bud break. This study is the first to directly demonstrate that fruiting is independent from old carbon reserves in masting trees, with significant implications for mechanistic models that explain mast seeding.

  17. High sugar-induced insulin resistance in Drosophila relies on the lipocalin Neural Lazarillo.

    Matthieu Y Pasco

    Full Text Available In multicellular organisms, insulin/IGF signaling (IIS plays a central role in matching energy needs with uptake and storage, participating in functions as diverse as metabolic homeostasis, growth, reproduction and ageing. In mammals, this pleiotropy of action relies in part on a dichotomy of action of insulin, IGF-I and their respective membrane-bound receptors. In organisms with simpler IIS, this functional separation is questionable. In Drosophila IIS consists of several insulin-like peptides called Dilps, activating a unique membrane receptor and its downstream signaling cascade. During larval development, IIS is involved in metabolic homeostasis and growth. We have used feeding conditions (high sugar diet, HSD that induce an important change in metabolic homeostasis to monitor possible effects on growth. Unexpectedly we observed that HSD-fed animals exhibited severe growth inhibition as a consequence of peripheral Dilp resistance. Dilp-resistant animals present several metabolic disorders similar to those observed in type II diabetes (T2D patients. By exploring the molecular mechanisms involved in Drosophila Dilp resistance, we found a major role for the lipocalin Neural Lazarillo (NLaz, a target of JNK signaling. NLaz expression is strongly increased upon HSD and animals heterozygous for an NLaz null mutation are fully protected from HSD-induced Dilp resistance. NLaz is a secreted protein homologous to the Retinol-Binding Protein 4 involved in the onset of T2D in human and mice. These results indicate that insulin resistance shares common molecular mechanisms in flies and human and that Drosophila could emerge as a powerful genetic system to study some aspects of this complex syndrome.

Nitrite-positive urines were actually 18% more likely to be associated with negative urine cultures in the setting of positive STI cases, (95% CI [4.95–30.42], p=0.0048. Antibiotics were prescribed for 295 patients with suspected UTI.

Chi-square analysis yielded a difference of these proportions of 32% (95% CI [23.92–39.62], p<0.0001. Conclusion: This study demonstrated that in female patients with STIs who have pyuria, there is a high prevalence of sterile pyuria. Our results suggest that reliance on pyuria or positive nitrite for the decision to add antimicrobial therapy empirically for a presumed urinary tract infection in cases in which an STI is confirmed or highly suspected is likely to result in substantial over-treatment.

    2018-04-09

    High prevalence mental disorders including depression, anxiety and substance use disorders are associated with high economic and disease burden. However, there is little information regarding the health state utility values of such disorders according to their clinical severity using comparable instruments across all disorders. This study reports utility values for high prevalence mental disorders using data from the 2007 Australian National Survey of Mental Health and Wellbeing (NSMHWB). Utility values were derived from the AQoL-4D and analysed by disorder classification (affective only (AD), anxiety-related only (ANX), substance use only (SUB) plus four comorbidity groups), severity level (mild, moderate, severe), symptom recency (reported in the past 30 days), and comorbidity (combination of disorders). The adjusted Wald test was applied to detect statistically significant differences of weighted means and the magnitude of difference between groups was presented as a modified Cohen's d. In total, 1526 individuals met criteria for a 12-month mental disorder. The mean utility value was 0.67 (SD = 0.27), with lower utility values associated with higher severity levels and some comorbidities. Utility values for AD, ANX and SUB were 0.64 (SD = 0.25), 0.71 (SD = 0.25) and 0.81 (SD = 0.19), respectively. No differences in utility values were observed between disorders within disorder groups. Utility values were significantly lower among people with recent symptoms (within past 30 days) than those without; when examined by diagnostic group, this pattern held for people with SUB, but not for people with ANX or AD. Health state utility values of people with high prevalence mental disorders differ significantly by severity level, number of mental health comorbidities and the recency of symptoms, which provide new insights on the burden associated with high prevalence mental disorders in Australia. The derived utility values can be used to populate future

    The human visual system contains a hierarchical sequence of modules that take part in visual perception at different levels of abstraction, i.e., superordinate, basic, and subordinate levels. One important question is to identify the "entry" level at which the visual representation is commenced in the process of object recognition. For a long time, it was believed that the basic level had a temporal advantage over two others. This claim has been challenged recently. Here we used a series of psychophysics experiments, based on a rapid presentation paradigm, as well as two computational models, with bandpass filtered images of five object classes to study the processing order of the categorization levels. In these experiments, we investigated the type of visual information required for categorizing objects in each level by varying the spatial frequency bands of the input image. The results of our psychophysics experiments and computational models are consistent. They indicate that the different spatial frequency information had different effects on object categorization in each level. In the absence of high frequency information, subordinate and basic level categorization are performed less accurately, while the superordinate level is performed well. This means that low frequency information is sufficient for superordinate level, but not for the basic and subordinate levels. These finer levels rely more on high frequency information, which appears to take longer to be processed, leading to longer reaction times. Finally, to avoid the ceiling effect, we evaluated the robustness of the results by adding different amounts of noise to the input images and repeating the experiments. As expected, the categorization accuracy decreased and the reaction time increased significantly, but the trends were the same. This shows that our results are not due to a ceiling effect. The compatibility between our psychophysical and computational results suggests that the temporal

  4. Energetic solutions of Rock Sandpipers to harsh winter conditions rely on prey quality

    Rock Sandpipers Calidris ptilocnemis have the most northerly non-breeding distribution of any shorebird in the Pacific Basin (upper Cook Inlet, Alaska; 61°N, 151°W). In terms of freezing temperatures, persistent winds and pervasive ice, this site is the harshest used by shorebirds during winter. We integrated physiological, metabolic, behavioural and environmental aspects of the non-breeding ecology of Rock Sandpipers at the northern extent of their range to determine the relative importance of these factors in facilitating their unique non-breeding ecology. Not surprisingly, estimated daily energetic demands were greatest during January, the coldest period of winter. These estimates were greatest for foraging birds, and exceeded basal metabolic rates by a factor of 6.5, a scope of increase that approaches the maximum sustained rate of energetic output by shorebirds during periods of migration, but far exceeds these periods in duration. We assessed the quality of their primary prey, the bivalve Macoma balthica, to determine the daily foraging duration required by Rock Sandpipers to satisfy such energetic demands. Based on size-specific estimates of M. balthica quality, Rock Sandpipers require over 13 h/day of foraging time in upper Cook Inlet in January, even when feeding on the highest quality prey. This range approaches the average daily duration of mudflat availability in this region (c. 18 h), a maximum value that annually decreases due to the accumulation of shore-fast ice. Rock Sandpipers are likely to maximize access to foraging sites by following the exposure of ice-free mudflats across the upper Cook Inlet region and by selecting smaller, higher quality M. balthica to minimize foraging times. Ultimately, this unusual non-breeding ecology relies on the high quality of their prey resources. Compared with other sites across their range, M. balthica from upper Cook Inlet have relatively light shells, potentially the result of the region

  5. You can't rely on color, yet we all do 2.0 (Manuscript Only)

    van Nes, Floris L.

    2014-01-01

    Everybody views and uses color from early childhood onwards. But this magnificent property of all objects around us turns out to be elusive if you try to specify it and communicate it to another person. Also, people often don't know what effects color may have under different conditions. However, color is so important and omnipresent, that people can hardly avoid to 'rely on it' - so they do, in particular on its predictability. Thus, there is a discrepancy between the seeming self-evidence of color and the difficulty in specifying it accurately, for the prevailing circumstances. In order to analyze this situation, and possibly remedy it, a short historic perspective of the utilization and specification of color is given. The 'utilization' includes the emotional effects of color, which are important in, for instance, interior decorating but also play a role in literature and religion. 'Specification' begins with the early efforts by scientists, philosophers and artists to bring some order and understanding in what was observed with and while using color. Color has a number of basic functions: embellishment; attracting attention; coding; and bringing order in text by causing text parts presented in the same color to be judged as belonging together. People with a profession that involves color choices for many others, such as designers and manufacturers of products, including electronic visual displays, should have a fairly thorough knowledge of colorimetry and color perception. Unfortunately, they often don't, simply because for 'practitioners' whose work involves different aspects, applying color being only one of those, the available tools for specifying and applying color turn out to be too difficult to use. Two consequences of an insufficient knowledge of the effects color may have are given here. The first of these consequences, on color blindness, relates to 8% of the population, but the second one, on reading colored text, bears on everyone. Practical

    Blood transfusion service centers in Nigeria screen donated blood for markers of HIV infection using antibody- (Ab) based rapid test and in some centers, positives are re-tested using Ab-based ELISA. Paucity of data exists on p24 antigen prevalence among HIV Ab-negative donors in Nigeria. This study aims at detecting HIV p24 antigen among prospective blood donors in Osun State, Nigeria. Prospective blood donors negative for HIV antibodies using Determine test kit were re-tested using BIORAD GENSCREEN Ultra Ag-Ab ELISA kit, a fourth-generation ELISA kit that detects HIV antibodies/p24 antigen. Of the 169 HIV Ab-negative prospective donors, 10 (5.9%) were positive for HIV p24 antigen and 70% (7/10) of them were in the age range 18-30 years. Results of this study show that blood transfusion is still one of the major routes of HIV transmission in Nigeria and a higher proportion is among youth. Inclusion of p24 antigen testing into the blood donor screening will help reduce transfusion associated HIV in Nigeria if Nucleic Acid Testing (NAT) of all blood donor samples is not affordable; also, HIV enlightenment programs tailored toward youth may help reduce this rate among donors since more young people donate blood in low/middle-income countries than in high-income countries.

Where and how early career researchers find scholarly information. Learned Publishing, 30(1, 19-29. http://dx.doi.org/10.1002/leap.1087 Abstract Objective – To examine the attitudes and information behaviours of early career researchers (ECRs when locating scholarly information. Design – Qualitative longitudinal study. Setting – Research participants from the United Kingdom, United States of America, China, France, Malaysia, Poland, and Spain. Subjects – A total 116 participants from various disciplines, aged 35 and younger, who were holding or had previously held a research position, but not in a tenured position. All participants held a doctorate or were in the process of earning one. Methods – Using structured interviews of 60-90 minutes, researchers asked 60 questions of each participant via face-to-face, Skype, or telephone interviews. The interview format and questions were formed via focus groups. Main Results – As part of a longitudinal project, results reported are limited to the first year of the study, and focused on three primary questions identified by the authors: where do ECRs find scholarly information, whether they use their smartphones to locate and read scholarly information, and what social media do they use to find scholarly information. Researchers describe how ECRs themselves interpreted the phrase scholarly information to primarily mean journal articles, while the researchers themselves had a much expanded definition to include professional and “scholarly contacts, ideas, and data” (p. 22. This research shows that Google and Google Scholar are widely used by ECRs for locating scholarly information regardless of discipline, language, or geography. Their analysis by country points to currency and the combined breadth-and-depth search experience that Google provides as

    The aim of the study was to assess the prevalence of antiretroviral drug resistance mutations in HIV-1 from recently diagnosed and untreated patients living in Conakry, Guinea-Conakry and in Niamey, Niger. The study was performed in two countries of Western Africa - Guinea-Conakry and Niger - using the same survey method in both sites. All newly HIV-1 diagnosed patients, naive of antiretroviral drugs, were consecutively included during September 2009 in each of the two sites. Protease and reverse transcriptase sequencing was performed using the ANRS procedures. Drug resistance mutations were identified according to the 2009 update surveillance drug resistance mutations. In Conakry, 99 patients were included, most of whom (89%) were infected with CRF02_AG recombinant virus. Resistance analysis among the 93 samples showed that ≥1 drug resistance mutation was observed in 8 samples, leading to a prevalence of primary resistance of 8.6% (95% CI 2.91-14.29%). In Niamey, 96 patients were included; a high diversity in HIV-1 subtypes was observed with 47 (51%) patients infected with CRF02_AG. Resistance analysis performed among the 92 samples with successful genotypic resistance test showed that ≥1 drug resistance mutation was observed in 6 samples, leading to a prevalence of primary resistance of 6.5% (95% CI 1.50-11.50%). We reported the first antiretroviral drug resistance survey studies in antiretroviral-naive patients living in Guinea-Conakry and in Niger. The prevalence of resistance was between 6% and 9% in both sites, which is higher than most of the other countries from Western Africa region.

  9. High prevalence of undiagnosed chronic kidney disease among at-risk population in Kinshasa, the Democratic Republic of Congo

    2009-07-01

    Full Text Available Abstract Background There is limited knowledge of Chronic Kidney Disease (CKD among high risk populations, especially in the developing countries. We report our study of testing for CKD in at-risk subjects. Methods In a cross-sectional study, 527 people from primary and secondary health care areas in the city of Kinshasa were studied from a random sample of at-risk out-patients with hypertension, diabetes, obesity, or HIV+. We measured blood pressure (BP, blood glucose level, proteinuria, body mass index, and estimated glomerular filtration rate (eGFR by MDRD equation using calibrated creatinine levels based on one random measurement. The associations between health characteristics, indicators of kidney damage (proteinuria and kidney function (2 were also examined. Results The prevalence of CKD in this study was 36%, but only 12% were aware of their condition. 4% of patients had stage 1 CKD, 6% stage 2, 18% stage 3, 2% stage 4, and 6% had stage 5. 24 hour quantitative proteinuria (>300 mg/day was found in 19%. In those with the at-risk conditions, the % of CKD was: 44% in patients with hypertension, 39% in those with diabetes; 16% in the obese and 12% in those who were HIV+. 82% of those with a history of diabetes had elevated serum glucose levels at screening (≥ 126 mg/dl. Only 6% of individuals with hypertension having CKD had reduced BP to lower than 130/80 mmHg. In multivariate analysis, diabetes, proteinuria and hypertension were the strongest determinants of CKD 3+. Conclusion It appears that one out of three people in this at-risk population has undiagnosed CKD and poorly controlled CKD risk factors. This growing problem poses clear challenges to this developing country. Therefore, CKD should be addressed through the development of multidisciplinary teams and improved communication between traditional health care givers and nephrology services. Attention to CKD risk factors must become a priority.

  10. Malaria epidemiology in low-endemicity areas of the northern coast of Ecuador: high prevalence of asymptomatic infections.

    The recent scale-up in malaria control measures in Latin America has resulted in a significant decrease in the number of reported cases in several countries including Ecuador, where it presented a low malaria incidence in recent years (558 reported cases in 2015) with occasional outbreaks of both Plasmodium falciparum and Plasmodium vivax in the coastal and Amazonian regions. This success in malaria control in recent years has led Ecuador to transition its malaria policy from control to elimination. This study evaluated the general knowledge, attitude and practices (KAP) about malaria, as well as its prevalence in four communities of an endemic area in northwest Ecuador. A total of 258 interviews to assess KAP in the community indicated that most people in the study area have a basic knowledge about the disease but did not use to contribute to its control. Six hundred and forty-eight blood samples were collected and analysed by thick blood smear and real-time PCR. In addition, the distribution of the infections was mapped in the study communities. Although, no parasites were found by microscopy, by PCR the total malaria prevalence was 7.5% (6.9% P. vivax and 0.6% P. falciparum), much higher than expected and comparable to that reported in endemic areas of neighbouring countries with higher malaria transmission. Serology using ELISA and immunofluorescence indicated 27% respondents for P. vivax and 22% respondents for P. falciparum. Results suggest that despite a great malaria reduction in Ecuador, transition from control to elimination would demand further improvement in malaria diagnostics, including active case detection to identify and treat parasite asymptomatic carriers, as well as community participation in its elimination.

  11. Multidrug resistant tuberculosis in prisons located in former Soviet countries: A systematic review.

    Maxwell Droznin

    Full Text Available A systematic literature review was performed to investigate the occurrence of multidrug-resistant tuberculosis (MDR TB in prisons located in countries formerly part of the Soviet Union.A systematic search of published studies reporting MDR TB occurrence in prisons located in former Soviet countries was conducted by probing PubMed and Cumulative Index Nursing and Allied Health Literature for articles that met predetermined inclusion criteria.Seventeen studies were identified for systematic review. Studies were conducted in six different countries. Overall, prevalence of MDR TB among prisoners varied greatly between studies. Our findings suggest a high prevalence of MDR TB in prisons of Post-Soviet states with percentages as high as 16 times more than the worldwide prevalence estimated by the WHO in 2014.All studies suggested a high prevalence of MDR TB in prison populations in Post-Soviet states.

    2014-01-01

    Full Text Available Background & objectives: Studies conducted to assess the prevalence of cardiovascular (CV risk factors among different regions of the country show variation in risk factors in different age groups and urban and rural population. We undertook this study to determine the prevalence of cardiovascular risk factors among urban adults in a north Indian city. Methods: In a cross-sectional survey, 2227 subjects aged ≥ 20 yr were studied from April 2008 to June 2009 in Urban Chandigarh, a north Indian city. Demographic history, anthropometry and blood pressure were assessed. Fasting, and 2 h capillary plasma glucose after 75 g glucose load, HDL-C and triglycerides were estimated. Results: The most prevalent cardiovascular risk factors in the age group of 20-29 yr was sedentary lifestyle (63%, while from fourth decade and onwards, it was overweight/obesity (59-85%. The second most common prevalent cardiovascular risk factor in the age group of 20-29 yr was overweight/obesity, in 30-49 yr sedentary lifestyle, in 50-69 yr hypertension and in subjects ≥70 yr, it was hypertriglyceridaemia. The prevalence of overweight/obesity, hypertension, dysglycaemia and smoking was almost double in subjects in the fourth decade of life, as compared to those in the third decade of life. The prevalence of CV risk factors significantly increased with age irrespective of gender and prevalence of low HDL-C was significantly more common in women as compared to men. Interpretation & conclusions: Sedentary lifestyle, obesity and low HDL-C are the most prevalent CV risk factors in subjects in the third and fourth decade of life in this north Indian population and clustering of these cardiovascular risk factors increases with advancing age. Strategies need to be formulated to target this population to prevent the epidemic of cardiovascular disease.

    Cardiovascular diseases are the leading cause of mortality among women in several countries. Early detection of subclinical atherosclerosis (SA) could enable the adoption of preventive measures to avoid cardiovascular events. This study aimed to determine the prevalence of SA in Brazilian asymptomatic postmenopausal women in Framingham Risk Score (FRS) low and intermediate groups. Computed tomography (CT) and ultrasound (US) scans were performed in 138 asymptomatic postmenopausal women (56.1 ± 4.9 years of age) to survey for coronary artery and aortic calcification (CT scan) and assess carotid intima-media thickness (CIMT) and identify carotid plaques (US). The mean FRS was 2.64 ± 2.13 %. The prevalence of increased CIMT, carotid plaques, increased CIMT and/or plaques, coronary artery calcification (CAC) >0 and aortic calcification (AC) were, respectively, 45.7, 37.7, 62.3, 23.9 and 45.7 %. Normal imaging tests were found in 22.4 %. SA, defined as at least one abnormal imaging test, was associated with age, FRS, waist-to-rip ratio, systolic and diastolic blood pressure, HDL-c and ApoA1 levels, and ApoA1/ApoB ratio. In logistic regression, SA was associated with higher age (OR 1.108, 95 % CI 1.010-1.215, p = 0.029) and lower ApoA1 levels (OR 0.979, 95 % CI 0.960-0.998, p = 0.029). SA was prevalent in Brazilian postmenopausal women with low and intermediate risk groups (FRS) and was associated with higher age and lower levels of ApoA1. Carotid atherosclerosis was the most common presentation of SA in this group.

    Full Text Available α-Amylase from Anoxybacillus sp. SK3-4 (ASKA is a thermostable enzyme that produces a high level of maltose from starches. A truncated ASKA (TASKA variant with improved expression and purification efficiency was characterized in an earlier study. In this work, TASKA was purified and immobilized through covalent attachment on three epoxide (ReliZyme EP403/M, Immobead IB-150P, and Immobead IB-150A and an amino-epoxide (ReliZyme HFA403/M activated supports. Several parameters affecting immobilization were analyzed, including the pH, temperature, and quantity (mg of enzyme added per gram of support. The influence of the carrier surface properties, pore sizes, and lengths of spacer arms (functional groups on biocatalyst performances were studied. Free and immobilized TASKAs were stable at pH 6.0–9.0 and active at pH 8.0. The enzyme showed optimal activity and considerable stability at 60 °C. Immobilized TASKA retained 50% of its initial activity after 5–12 cycles of reuse. Upon degradation of starches and amylose, only immobilized TASKA on ReliZyme HFA403/M has comparable hydrolytic ability with the free enzyme. To the best of our knowledge, this is the first report of an immobilization study of an α-amylase from Anoxybacillus spp. and the first report of α-amylase immobilization using ReliZyme and Immobeads as supports.

  20. Head and neck squamous cell carcinoma of unknown primary: Outcomes of a pre-defined institutional treatment policy in a region with a high prevalence of skin cancer.

    2018-02-01

    To determine the rate of subsequent primary site failure in patients with head and neck squamous cell carcinoma of unknown primary (UKP HNSCC) in a region with a high prevalence of cutaneous squamous cell carcinoma, according to a pre-determined institutional policy. Secondary aims included regional and distant control, and overall survival. Patients presenting between April 2005 and June 2016 to the Princess Alexandra Hospital Head and Neck Multidisciplinary Meeting with UKP HNSCC from either presumed mucosal or cutaneous sites treated with curative intent were eligible. Patients with presumed mucosal origin were treated with radiation therapy (RT) with or without chemotherapy, while patients with presumed cutaneous SCC were treated with surgery and post-operative RT with or without chemotherapy. A total of 63 patients met the inclusion criteria. Median follow up duration was 3.9 years (IQR 2.07-5.14). There were no subsequent primary site failures. The rate of nodal failure among presumed mucosal patients was 11.5%, and 8.1% among presumed cutaneous patients. The rate of distant metastatic failure was 11.1% among all patients. The estimated 5 year overall survival was 71.2% (95% CI 59.2-85.7%). Treatment according to our pre-defined institutional policy for UKP HNSCC in a region with a high prevalence of cutaneous SCC appears to be safe and effective with low rates of mucosal primary emergence and nodal failure.

  1. High prevalence of tuberculosis and insufficient case detection in two communities in the Western Cape, South Africa.

    Mareli Claassens

    Full Text Available In South Africa the estimated incidence of all forms of tuberculosis (TB for 2008 was 960/100000. It was reported that all South Africans lived in districts with Directly Observed Therapy, Short-course. However, the 2011 WHO report indicated South Africa as the only country in the world where the TB incidence is still rising.To report the results of a TB prevalence survey and to determine the speed of TB case detection in the study communities.In 2005 a TB prevalence survey was done to inform the sample size calculation for the ZAMSTAR (Zambia South Africa TB and AIDS Reduction trial. It was a cluster survey with clustering by enumeration area; all households were visited within enumeration areas and informed consent obtained from eligible adults. A questionnaire was completed and a sputum sample collected from each adult. Samples were inoculated on both liquid mycobacterium growth indicator tube (MGIT and Löwenstein-Jensen media. A follow-up HIV prevalence survey was done in 2007.In Community A, the adjusted prevalence of culture positive TB was 32/1000 (95%CI 25-41/1000 and of smear positive TB 8/1000 (95%CI 5-13/1000. In Community B, the adjusted prevalence of culture positive TB was 24/1000 (95%CI 17-32/1000 and of smear positive TB 9/1000 (95%CI 6-15/1000. In Community A the patient diagnostic rate was 0.38/person-year while in community B it was 0.30/person-year. In both communities the adjusted HIV prevalence was 25% (19-30%.In both communities a higher TB prevalence than national estimates and a low patient diagnostic rate was calculated, suggesting that cases are not detected at a sufficient rate to interrupt transmission. These findings may contribute to the rising TB incidence in South Africa. The TB epidemic should therefore be addressed rapidly and effectively, especially in the presence of the concurrently high HIV prevalence.

  2. Hypovitaminosis D and mild hypocalcaemia are highly prevalent among young Vietnamese children and women and related to low dietary intake.

    Arnaud Laillou

    Full Text Available INTRODUCTION: In many developing countries including Vietnam, data are lacking on vitamin D and calcium deficiencies whereas those deficiencies can play an important role in the development of bone health and possibly non-communicable diseases. The purpose of this study was to determine the overall prevalence of vitamin D and calcium deficiencies in women and young children and their nutritional related risk factors. METHODS: A cross-sectional study conducted among 595 women of reproductive age and 532 children <5 years from 19 provinces of Vietnam. For each individual, data concerning daily diet, socioeconomic group, anthropometric status were obtained, and plasma concentrations of calcium and vitamin D were measured. RESULTS: The prevalence of hypovitaminosis D status was very high, with the prevalence of vitamin D deficiency (25(OHD<30 nmol/L and insufficiency (25(OHD between 30-49.9 nmol/L being 17% and 40% in women and 21% and 37% in children, respectively. Using more liberal cut-off of 75 nmol/L, approximately 90% of the women and children were classified as having hypovitaminosis D. Overweight/obese women had a 2 times lower risk (OR = 0.46, [0.24-0.90] for vitamin D deficiency than non-overweight and non-obese women. No participant had severe calcium deficiency but moderate and mild hypocalcaemia (plasma calcium concentrations between 1.15-0.9 mmol/L for mild deficiency and between 0.9-0.8 mmol/L for moderate deficiency affected respectively 14% and 83% of the women with 97% of the children having mild hypocalcaemia. Women and children consumed about 1% of the Institute of Medicine (IOM recommended nutrient intake (RNI for vitamin D and less than 43% of the RNI for calcium. CONCLUSION: Our study suggests that calcium and vitamin D deficiencies represent a major public health concern in Vietnam. Thus, actions to improve the vitamin D and calcium status of the Vietnamese population should be considered.

  3. High prevalence of curable sexually transmitted infections among pregnant women in a rural county hospital in Kilifi, Kenya.

    Simon Chengo Masha

    Full Text Available Women attending antenatal care (ANC in resource-limited countries are frequently screened for syphilis and HIV, but rarely for other sexually transmitted infections (STIs. We assessed the prevalence of curable STIs, defined as infection with either Chlamydia trachomatis or Neisseria gonorrhoeae or Trichomonas vaginalis, from July to September 2015.In a cross-sectional study, women attending ANC at the Kilifi County Hospital, Kenya, had a urine sample tested for C. trachomatis/N. gonorrhoeae by GeneXpert® and a vaginal swab for T. vaginalis by culture. Bacterial vaginosis (BV was defined as a Nugent score of 7-10 of the Gram stain of a vaginal smear in combination with self-reported vaginal discharge.

    Women attending antenatal care (ANC) in resource-limited countries are frequently screened for syphilis and HIV, but rarely for other sexually transmitted infections (STIs). We assessed the prevalence of curable STIs, defined as infection with either Chlamydia trachomatis or Neisseria gonorrhoeae or Trichomonas vaginalis, from July to September 2015. In a cross-sectional study, women attending ANC at the Kilifi County Hospital, Kenya, had a urine sample tested for C. trachomatis/N. gonorrhoeae by GeneXpert® and a vaginal swab for T. vaginalis by culture. Bacterial vaginosis (BV) was defined as a Nugent score of 7-10 of the Gram stain of a vaginal smear in combination with self-reported vaginal discharge. Genital ulcers were observed during collection of vaginal swabs. All women responded to questions on socio-demographics and sexual health and clinical symptoms of STIs. Predictors for curable STIs were assessed in multivariable logistic regression. A total of 42/202 (20.8%, 95% confidence interval (CI):15.4-27.0) women had a curable STI. The prevalence was 14.9% for C. trachomatis (95% CI:10.2-20.5), 1.0% for N. gonorrhoeae (95% CI: 0.1-3.5), 7.4% for T. vaginalis (95% CI:4.2-12.0), 19.3% for BV (95% CI: 14.1-25.4) and 2.5% for genital ulcers (95% CI: 0.8-5.7). Predictors for infection with curable STIs included women with a genital ulcer (adjusted odds ratio (AOR) = 35.0, 95% CI: 2.7-461.6) compared to women without a genital ulcer, women who used water for cleaning after visiting the toilet compared to those who used toilet paper or other solid means (AOR = 4.1, 95% CI:1.5-11.3), women who reported having sexual debut ≤ 17 years compared to women having sexual debut ≥18 years (AOR = 2.7, 95% CI:1.1-6.6), and BV-positive women (AOR = 2.7, 95% CI:1.1-6.6) compared to BV-negative women.

    In dentistry, a luting agent is a viscous material placed between tooth structure and a prosthesis that by polymerization firmly attach the prosthesis to the tooth structure. Luting agents contact a large area of dentin when used for crown cementation. There is little information on biocompatibility tests, especially on the effect of electron beam irradiation on cytotoxicity for luting resin cements. To determine the in vitro cytotoxicity and genotoxicity of Rely X luting cement on human lymphocyte cells before and after irradiation. Rely X luting cement was obtained commercially. Samples were prepared as per the ISO standard size of 25x2x2 mm using polytetrafluoroethylene teflon mould and divided into two groups - non irradiated and irradiated groups. The samples in irradiated category were exposed to 200 Gy of electron beam irradiation at Microtron Centre, Mangalore University, Mangalore, India. For hemolysis the samples were immersed in phosphate buffer saline and incubated at 370℃ for 24 hrs, 7 days and 14 days. 200 μl of 24 hr material extract was mixed with human peripheral blood lymphocyte tested for comet assay by single cell DNA comet assay. Hemolytic activity of non irradiated Rely X luting cement after 24 hrs, 7 days and 14 days was 54.78±1.48, 69.91±2.41 and 43.21±0.92 respectively whereas hemolytic activity of irradiated Rely X luting cement after 24 hrs, 7 days and 14 days was 91.8±8.29, 56.95±19.7 and 41.34±12.30. The irradiation of Rely X luting cement with 200 Gy dose of electron beam irradiation caused an increase in the frequency of DNA damage when compared to that of the non-irradiated group. Based on the experimental condition, it is concluded that incomplete polymerization of the dental luting cements has resulted in the elution of the resin components which are responsible for the cytotoxicity and genotoxicity of Rely X luting cement on human lymphocyte cells.

  6. Childhood overweight, obesity, and the metabolic syndrome in developing countries.

    Kelishadi, Roya

    2007-01-01

    The incidence of chronic disease is escalating much more rapidly in developing countries than in industrialized countries. A potential emerging public health issue may be the increasing incidence of childhood obesity in developing countries and the resulting socioeconomic and public health burden faced by these countries in the near future. In a systematic review carried out through an electronic search of the literature from 1950-2007, the author compared data from surveys on the prevalence of overweight, obesity, and the metabolic syndrome among children living in developing countries. The highest prevalence of childhood overweight was found in Eastern Europe and the Middle East, whereas India and Sri Lanka had the lowest prevalence. The few studies conducted in developing countries showed a considerably high prevalence of the metabolic syndrome among youth. These findings provide alarming data for health professionals and policy-makers about the extent of these problems in developing countries, many of which are still grappling with malnutrition and micronutrient deficiencies. Time trends in childhood obesity and its metabolic consequences, defined by uniform criteria, should be monitored in developing countries in order to obtain useful insights for primordial and primary prevention of the upcoming chronic disease epidemic in such communities.

    Thalassemia can lead to severe transfusion-dependent anemia, and it is the most common genetic disorder in Malaysia. This paper aims to determine the prevalence of thalassemia in the Kadazandusuns, the largest indigenous group in Sabah, East Malaysia. α- and β-thalassemia were confirmed in 33.6% and 12.8%, of the individuals studied respectively. The high prevalence of α- and β-thalassemia in the Kadazandusuns indicates that thalassemia screening, genetic counseling, and prenatal diagnosis should be included as part of their healthcare system. This preliminary paper serves as a baseline for further investigations into the health and genetic defects of the major indigenous population in Sabah, East Malaysia.

    The aim of the study was to elucidate the association between the zoonotic pathogen Salmonella and a population of land iguana, Colonophus subcristatus, endemic to Galápagos Islands in Ecuador. We assessed the presence of Salmonella subspecies and serovars and estimated the prevalence of the pathogen in that population. Additionally, we investigated the genetic relatedness among isolates and serovars utilising pulsed field gel electrophoresis (PFGE) on XbaI-digested DNA and determined the antimicrobial susceptibility to a panel of antimicrobials. The study was carried out by sampling cloacal swabs from animals (n = 63) in their natural environment on in the island of Santa Cruz. A high prevalence (62/63, 98.4%) was observed with heterogeneity of Salmonella subspecies and serovars, all known to be associated with reptiles and with reptile-associated salomonellosis in humans. Serotyping revealed 14 different serovars among four Salmonella enterica subspecies: S. enterica subsp. enterica (n = 48), S. enterica subsp. salamae (n = 2), S. enterica subsp. diarizonae (n = 1), and S. enterica subsp. houtenae (n = 7). Four serovars were predominant: S. Poona (n = 18), S. Pomona (n = 10), S. Abaetetuba (n = 8), and S. Newport (n = 5). The S. Poona isolates revealed nine unique XbaI PFGE patterns, with 15 isolates showing a similarity of 70%. Nine S. Pomona isolates had a similarity of 84%. One main cluster with seven (88%) indistinguishable isolates of S. Abaetetuba was observed. All the Salmonella isolates were pan-susceptible to antimicrobials representative of the most relevant therapeutic classes. The high prevalence and absence of clinical signs suggest a natural interaction of the different Salmonella serovars with the host species. The interaction may have been established before any possible exposure of the iguanas and the biocenosis to direct or indirect environmental factors influenced by the use of antimicrobials in agriculture

    Adults of the peri-urban Peruvian shantytown of Lomas de Zapallal have a high prevalence of risk factors for developing cardiovascular disease (CVD)-likely due to behavioral choices established during childhood and adolescence. To guide the development of community-based risk reduction programs, we assessed the prevalence of risk factors for developing CVD among adolescents. We collected cross sectional data from adolescents of Peruvian peri-urban shantytown to evaluate four domains of CVD risk factors: (1) clinical (blood pressure, fasting blood glucose, and blood lipids), (2) anthropometric (height, weight, and waist circumference), (3) behavioral (physical activity, diet, and substance abuse), and (4) psychosocial (mental health and violence). We enrolled 275 adolescents (56.4% female, mean age 14 years). Prevalence of overweight or obese status was 27.8%. High blood pressure was more common in males (37.4%) than females (20.5%) (p = 0.002). Total cholesterol was elevated (>170 mg/dL) in nearly half (45.5%) of the adolescents, and 71% had impaired fasting blood glucose (>100 mg/dL). Females were less likely to exercise daily (95.4%) than males (84.2%) (p = 0.002) but reported higher rates of depression (66.4%), anhedonia (67.6%), and self-harm behavior (37.9%) (all p < 0.01). Adolescents living in the peri-urban population of Puente Piedra had high prevalence of risk factors for future development of CVD; preventative efforts focused on improving nutrition, increasing physical inactivity, and addressing mental health conditions could reduce such risk factors.

    Staphylococcus aureus is highly prevalent among patients with atopic dermatitis (AD), and this pathogen may trigger and aggravate AD lesions. The aim of this study was to determine the prevalence of S. aureus in the nares of pediatric subjects and verify the phenotypic and molecular characteristics of the isolates in pediatric patients with AD. Isolates were tested for antimicrobial susceptibility, SCCmectyping, and Panton-Valentine Leukocidin (PVL) genes. Lineages were determined by pulsed-field gel electrophoresis and multilocus sequence typing (MLST). AD severity was assessed with the Scoring Atopic Dermatitis (SCORAD) index. Among 106 patients, 90 (85%) presented S. aureus isolates in their nares, and 8 also presented the pathogen in their skin infections. Two patients had two positive lesions, making a total of 10 S. aureusisolates from skin infections. Methicillin-resistant S. aureus(MRSA) was detected in 24 (26.6%) patients, and PVL genes were identified in 21 (23.3%), including 6 (75%) of the 8 patients with skin lesions but mainly in patients with severe and moderate SCORAD values (P=0.0095). All 24 MRSA isolates were susceptible to trimethoprim/sulfamethoxazole, while 8 isolates had a minimum inhibitory concentration (MIC) to mupirocin >1024 μg/mL. High lineage diversity was found among the isolates including USA1100/ST30, USA400/ST1, USA800/ST5, ST83, ST188, ST718, ST1635, and ST2791. There was a high prevalence of MRSA and PVL genes among the isolates recovered in this study. PVL genes were found mostly among patients with severe and moderate SCORAD values. These findings can help clinicians improve the therapies and strategies for the management of pediatric patients with AD.

    Rapid and accurate diagnosis of Clostridium difficile infection (CDI) is crucial for patient care, infection control, and efficient surveillance. We evaluated C. DIFF QUIK CHEK COMPLETE (QCC; TechLab), which detects glutamate dehydrogenase (GDH) antigen (QCC-Ag) and toxin A/B (QCC-Tox) simultaneously, and compared it to the laboratory diagnostics for CDI currently in use in a tertiary hospital setting with a high prevalence of CDI. QCC, RIDASCREEN C. difficile toxin A/B assay (Toxin EIA; R-Biopharm AG), chromID C. difficile agar (bioMérieux) culture (ChromID culture), and Xpert C. difficile PCR assay (Xpert PCR; Cepheid) were performed according to the manufacturers' instructions. Performances of the assays were compared against that of Xpert PCR as a reference. Of the 231 loose stool specimens, 83 (35.9%) were positive by Xpert PCR. The sensitivity, specificity, and positive and negative predictive values were 97.6%, 93.9%, 90.0%, and 98.6%, respectively, for QCC-Ag and 55.4%, 100%, 100%, and 80.0%, respectively, for QCC-Tox. The median threshold cycle values of the QCC-Tox(+) specimens were lower than those of the QCC-Tox(-) specimens. Results of QCC as an initial screening test were confirmed in 81.0% (187/231) of samples; these specimens did not require further testing. QCC is a rapid, easy, and cost-effective method that would be a useful first-line screening assay for laboratory diagnosis of CDI in a tertiary hospital with a high prevalence of CDI. A two-step algorithm using QCC as an initial screening tool, followed by Xpert PCR as a confirmatory test, is a practical and cost-effective approach.

  18. Phonological memory in sign language relies on the visuomotor neural system outside the left hemisphere language network.

    Kanazawa, Yuji; Nakamura, Kimihiro; Ishii, Toru; Aso, Toshihiko; Yamazaki, Hiroshi; Omori, Koichi

    Sign language is an essential medium for everyday social interaction for deaf people and plays a critical role in verbal learning. In particular, language development in those people should heavily rely on the verbal short-term memory (STM) via sign language. Most previous studies compared neural activations during signed language processing in deaf signers and those during spoken language processing in hearing speakers. For sign language users, it thus remains unclear how visuospatial inputs are converted into the verbal STM operating in the left-hemisphere language network. Using functional magnetic resonance imaging, the present study investigated neural activation while bilinguals of spoken and signed language were engaged in a sequence memory span task. On each trial, participants viewed a nonsense syllable sequence presented either as written letters or as fingerspelling (4-7 syllables in length) and then held the syllable sequence for 12 s. Behavioral analysis revealed that participants relied on phonological memory while holding verbal information regardless of the type of input modality. At the neural level, this maintenance stage broadly activated the left-hemisphere language network, including the inferior frontal gyrus, supplementary motor area, superior temporal gyrus and inferior parietal lobule, for both letter and fingerspelling conditions. Interestingly, while most participants reported that they relied on phonological memory during maintenance, direct comparisons between letters and fingers revealed strikingly different patterns of neural activation during the same period. Namely, the effortful maintenance of fingerspelling inputs relative to letter inputs activated the left superior parietal lobule and dorsal premotor area, i.e., brain regions known to play a role in visuomotor analysis of hand/arm movements. These findings suggest that the dorsal visuomotor neural system subserves verbal learning via sign language by relaying gestural inputs to

    Full Text Available The same branding principles are used for countries as they are used for the products, only the methods are different. Countries are competing among themselves in tourism, foreign investments and exports. Country turnover is at the level that the country's reputation is. The countries that begin as unknown or with a bad image will have limits in operations or they will be marginalized. As a result they will be at the bottom of the international influence scale. On the other hand, countries with a good image, like Germany (despite two world wars will have their products covered with a special "aura".

    2017-10-01

    To examine the availability of radiotherapy in small countries. A small country was defined as a country with a population less than one million persons. The economic status of each country was defined using the World Bank Classification. The number of cancers in each country was obtained from GLOBOCAN 2012. The number of cancer cases with an indication or radiotherapy was calculated using the CCORE model. There were 41 countries with a population of under 1 million; 15 were classified as High Income, 15 Upper Middle Income, 10 Lower Middle Income and one Low Income. 28 countries were islands. Populations ranged from 799 (Holy See) to 886450 (Fiji) and the total number of cancer cases occurring in small countries was 21,043 (range by country from 4 to 2476). Overall the total number of radiotherapy cases in small countries was 10982 (range by country from 2 to 1239). Radiotherapy was available in all HIC islands with 80 or more new cases of cancer in 2012 but was not available in any LMIC island. Fiji was the only LMIC island with a large radiotherapy caseload. Similar caseloads in non-island LMIC all had radiotherapy services. Most non-island HIC did not have radiotherapy services presumably because of the easy access to radiotherapy in neighbouring countries. There are no radiotherapy services in any LMIC islands.

    2015-02-01

    Full Text Available Amphimerus sp. is a liver fluke which recently has been shown to have a high prevalence of infection among an indigenous group, Chachi, who reside in a tropical rainforest in the northwestern region of Ecuador. Since it is unknown which animals can act as a reservoir and/or definitive hosts for Amphimerus sp. in this endemic area, a study was done to determine the prevalence of infection in domestic cats and dogs. This information is important to understand the epidemiology, life cycle and control of this parasite.In July 2012, three Chachi communities located on Rio Cayapas, province of Esmeraldas, were surveyed. A total of 89 of the 109 registered households participated in the study. Of the 27 cats and 43 dogs found residing in the communities, stool samples were collected from 14 cats and 31 dogs (total of 45 animals and examined microscopically for the presence of Amphimerus eggs. The prevalence of infection was 71.4% in cats and 38.7% in dogs, with similar rates of infection in all three communities. Significantly more cats were infected than dogs (p = 0.042.The data show a high rate of Amphimerus sp. infection in domestic cats and dogs residing in Chachi communities. It can be concluded that these animals act as definitive and reservoir hosts for this liver fluke and that amphimeriasis is a zoonotic disease. These findings provide important epidemiological data which will aid in the development and implementation of control strategies against the transmission of Amphimerus.

    Porocephalus crotali is a pentastomid parasite that uses crotaline snakes as definitive hosts and a variety of rodents as intermediate hosts. A study of definitive and intermediate pentastome hosts on Cumberland Island, Georgia, revealed high prevalence of P. crotali infection in crotalid snakes as well as several mammalian species. Despite the presence of numerous nymphs in some animals, clinical signs of disease were not observed. In intermediate hosts, the liver, mesentery, and reproductive organs were most commonly infected. No gross evidence of tissue damage was noted in association with the numerous encysted nymphal pentastomes, and histopathology demonstrated minimal reaction to the encysted nymphs. Partial 18S rRNA gene sequences confirmed the parasites were P. crotali. In contrast to many previous reports in rodents, the prevalence on this barrier island was high, and this is the first report of Virginia opossums (Didelphis virginiana) and any insectivore species as intermediate hosts. Although generally not considered pathogenic, the long-term consequences of high nymph intensities on individuals deserve attention.

    This paper presents key methodological approaches and challenges in implementing and analysing the first round of the integrated biobehavioural assessment of most-at-risk populations, conducted in conjunction with evaluation of Avahan, the India AIDS initiative. The survey collected data on HIV risk behaviours, sexually transmitted infections and HIV prevalence in 29 districts in six high-prevalence states of India. Groups included female sex workers and clients, men who have sex with men, injecting drug users and truck drivers. Strategies for overcoming some challenges of the large-scale surveys among vulnerable populations, including sampling hidden populations, involvement of the communities targeted by the survey, laboratory and quality control in remote, non-clinic field settings, and data analysis and data use are presented. Satisfying the need for protocols, guidelines and tools that allowed for sufficient standardization, while being tailored enough to fit diverse local situations on such a large scale, with so many implementing partners, emerged as a major management challenge. A major lesson from the first round is the vital importance of investing upfront time in tailoring the sampling methods, data collection instruments, and analysis plan to match measurement objectives. Despite the challenges, the integrated biobehavioural assessment was a huge achievement, and was largely successful in providing previously unavailable information about the HIV situation among populations that are critical to the curtailment of HIV spread in India. Lessons from the first round will be used to evolve the second round into an exercise with increased evaluative capability for Avahan.

    Vitamin D status, as indicated by 25-hydroxyvitamin D is inversely associated with adiposity, glucose homeostasis, lipid profiles, and blood pressure along with its classic role in calcium homeostasis and bone metabolism. It is also shown to be inversely associated with metabolic syndrome and cardiovascular diseases in western populations. However, evidence from the Asian population is limited. Therefore, we aim to study the prevalence of vitamin D insufficiency (obesity, HDL-cholesterol, diastolic blood pressure), insufficient Vitamin D status was significantly associated with 1-year age increments (OR: 0.93; 95% CI: 0.88, 0.98), being female (OR: 8.68; 95% CI: 5.08, 14.83) and abdominal obesity (OR: 2.57; 95% CI: 1.51, 4.39). Respondents with insufficient vitamin D were found to have higher odds of having Metabolic Syndrome (OR: 1.73; 95% CI: 1.02, 2.92) after adjusting for age and sex. Our results highlight the high prevalence of vitamin D insufficiency among Malay adults in Kuala Lumpur. Vitamin D insufficiency is independently associated with younger age, female sex and greater abdominal obesity. Vitamin D insufficiency is also associated with Metabolic Syndrome.

  7. Risk behaviors of 15–21 year olds in Mexico lead to a high prevalence of sexually transmitted infections: results of a survey in disadvantaged urban areas

    2006-02-01

    Full Text Available Abstract Background Due to the fact that adolescents are more likely to participate in high-risk behaviors, this sector of the population is particularly vulnerable to contracting sexually transmitted infections (STIs and resultant health problems. Methods A survey was carried out among adolescents from poor homes in 204 small-urban areas of Mexico. Information was collected in relation to risk behaviors and socio-economic environment. A sub-group of the participants also provided blood and urine samples which were analyzed to detect sexually transmitted infections. Results The presence of Chlamydia was detected in nearly 8% of participants who had stated that they were sexually active (18% and approximately 12% were positive for herpes type 2-specific antibodies. For both, a greater proportion of girls resulted positive compared to boys. The presence of these biological outcomes of sexual risk behavior was associated with other risk behaviors (smoking, but not with self-reported indicators of protected sex (reported use of condom during most recent sexual activity. Conclusion The results presented in this study show a startlingly high prevalence of HSV-2 among sexually active Mexican adolescents in poor urban areas, suggesting that this group has participated to a great extent in risky sexual practices. The relationships between socioeconomic environment and adolescent risk behavior need to be better understood if we are to design preventive interventions that modify the determinants of risk behaviors.

    Full Text Available Background: The level of physical fitness in south Asian immigrants living in Norway is largely unknown, but the level of physical activity seems to be low, possibly in part explaining their high prevalence of diabetes and cardiovascular diseases. However, previous studies have used self-reported measures of physical activity, and it might be questioned whether the previous data reflect the true physical activity level.Aim: To describe objectively measured physical activity level, cardiorespiratory fitness and diabetes risk in a group of Pakistani immigrant men living in Oslo, Norway.Methods: One hundred and fifty Pakistani immigrant men in the age group 25-60 years were included. Physical activity level was assessed with an accelerometer. Cardiorespiratory fitness was measured until exhaustion on a treadmill, and diabetes risk was evaluated with an oral glucose tolerance test.Results: Mean age was 37.3 years (SD=7.7. Total physical activity level was 308 counts/min (SD=131, and peak oxygen uptake was 34.2 ml·kg-1·min-1 (SD=5.6. Fifty percent of the participants had the metabolic syndrome, and 76% were obese. Physical activity level and cardiorespiratory fitness level were lower, and prevalence of the metabolic syndrome higher in a subgroup of taxi drivers as compared with those inother occupations (P<0.05.Conclusions: Physical activity and cardiorespiratory fitness levels are low and diabetes risk high among Pakistani immigrant men living in Oslo, especially in taxi drivers

  9. Corneal and refractive astigmatism in a sample of 3- to 5-year-old children with a high prevalence of astigmatism.

    1999-12-01

    To examine the relation between corneal and refractive astigmatism in a sample of pre-school-age Native American children with a high prevalence of astigmatism. Subjects were 250 Tohono O'Odham children, 3 to 5 years of age. Each child had corneal astigmatism measured with the Marco Nidek KM-500 portable autokeratometer without pupil dilation, and with the Nikon Retinomax K-Plus portable autorefractor/autokeratometer without and with pupil dilation. Refractive astigmatism was measured using the Retinomax K-Plus, with cycloplegia, confirmed by retinoscopy. Corneal astigmatism exceeded refractive astigmatism, with a median vector dioptric difference of 0.88 D for the KM-500, 0.76 D for the Retinomax K-Plus without dilation, and 0.75 for the Retinomax K-Plus with dilation. The relation between corneal and refractive astigmatism was adequately described by the modification by Grosvenor et al. of Javal's rule, but not by laval's rule. The results are in agreement with data reported previously for older Native American and non-Native American populations. The modified laval's rule adequately describes the relation between corneal and refractive astigmatism in a population; however, this rule does not provide accurate prediction of refractive astigmatism in individual children or adults.

    Girls with Turner syndrome are prone to cholesteatoma, a serious suppurative middle ear disease. We aimed to confirm its high prevalence in Turner syndrome, identify risk factors and suggest possible strategies for earlier detection. We reviewed 179 girls with Turner syndrome between 1989 and 2012 to identify cases of cholesteatoma. Seven girls (3.9%) had cholesteatoma (index girls) and each was compared with three age-matched girls without cholesteatoma (comparison girls). All the index girls had either the 45,X or 45,X/46X,i(Xq) karyotypes. Nine ears were initially affected, with three recurrences in two girls. Median age at first cholesteatoma presentation was 11.9 years (range: 7.5-15.2), with otorrhoea for three (range: one to seven) months in all 12 affected ears. Index girls had a significantly higher proportion of previous recurrent acute (p = 0.007) and chronic otitis media (p = 0.008), chronic perforation (p = 0.038) aural polyps (p Turner syndrome. Risk factors include 45,X and 46,XiXq karyotypes; a history of chronic otitis media, tympanic membrane retraction and persistent otorrhoea; and older age. Earlier recognition of ear disease is needed and otoscopy training for paediatricians caring for Turner syndrome patients may be beneficial. ©2014 Foundation Acta Paediatrica.

    The present study aimed to assess the adequacy of Ca intake and major food sources of Ca in Korean children and adolescents. A cross-sectional study. Data from the Korean National Health and Nutrition Examination Survey (KNHANES) 2007-2010. We analysed the daily Ca intake, major food sources of Ca and the prevalence of inadequate Ca intake in the study population. Ca intake was categorized as inadequate when the participant's daily Ca intake was less than the Estimated Average Requirement. Subject The study population consisted of 7233 children and adolescents (3973 boys, 3260 girls; aged 1-18 years). Mean Ca intake was 510·2 mg/d in boys and 431·7 mg/d in girls. Overall, 75·0 % of adolescents (boys 71·6 %, girls 79·1 %) had inadequate Ca intake. The prevalence of inadequate Ca intake increased significantly from toddlers (45-55 %) to adolescents (78-86 %) in both genders. The highest ranked food sources for Ca were dairy products (35·0 %), followed by vegetables (17·3 %), grains (11·3 %) and seafood (9·9 %). Ca intake from dairy products decreased significantly from 57 % in toddlers to 30 % in adolescents, while Ca intakes from other foods increased with age. Inadequate Ca intake is highly prevalent and increased with age in Korean children and adolescents. It should be emphasized to encourage children and adolescents to eat more Ca-rich products to meet their Ca needs.

    Little data are available for sub-Saharan African women on changes in body composition in menopause transition (MT). The study aimed to determine whether there are differences in body adiposity, lean muscle mass, and bone mineral density (BMD) across MT groups in urban African women, who have a high prevalence of obesity and HIV infection, and if this is related to an altered hormonal milieu. Participants were 702 black urban women. Menopause stage was defined using STRAW+10 criteria. Levels of follicle stimulating hormone (FSH), estradiol (E2), dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), testosterone (T) and sex hormone blinding globulin (SHBG) were measured. Body composition was measured with dual-energy X-ray absorptiometry (DXA) and ultrasound scans. Whole body lean mass (p=0.002) and BMD (pART) correlated negatively with total fat mass (β=-2.92, p=0.008) and total bone mineral content (BMC; β=-78.8, p=0.003). The MT in this population is characterized by lower whole body lean mass and BMD in post- compared to premenopausal subjects but there are minimal differences in fat mass. Lower lean mass and BMD were associated with higher FSH and lower E2 serum levels, respectively. Use of ART was associated with lower fat mass and BMC. Copyright © 2015. Published by Elsevier Inc.

    Full Text Available Abstract Background The goal of this study was to identify the clinicopathological factors of co-existing papillary thyroid cancer (PTC in patients with Hashimoto���s thyroiditis (HT and provide information to aid in the diagnosis of such patients. Methods This study included 6109 patients treated in a university-based tertiary care cancer hospital over a 3-year period. All of the patients were categorised based on their final diagnosis. Several clinicopathological factors, such as age, gender, nodular size, invasive status, central compartment lymph node metastasis (CLNM and serum thyroid-stimulating hormone (TSH level, were compared between the various groups of patients. Results There were 653 patients with a final diagnosis of HT. More PTC was found in those with HT (58.3%; 381 of 653 than those without HT (2416 of 5456; 44.3%; p Conclusion PTC and HT have a close relationship in this region of highly prevalent HT disease. Based on the results of our study, we hypothesise that long-term HT leads to elevated serum TSH, which is the real risk factor for thyroid cancer.

  14. Influence of Computerized Sounding Out on Spelling Performance for Children who do and not rely on AAC

    2015-01-01

    Purpose Spelling is an important skill for individuals who rely on augmentative alternative communication (AAC). The purpose of this study was to investigate how computerized sounding out influenced spelling accuracy of pseudo-words. Computerized sounding out was defined as a word elongated, thus providing an opportunity for a child to hear all the sounds in the word at a slower rate. Methods Seven children with cerebral palsy, four who use AAC and three who do not, participated in a single subject AB design. Results The results of the study indicated that the use of computerized sounding out increased the phonologic accuracy of the pseudo-words produced by participants. Conclusion The study provides preliminary evidence for the use of computerized sounding out during spelling tasks for children with cerebral palsy who do and do not use AAC. Future directions and clinical implications are discussed. PMID:24512195

    Humans excel at assessing conspecific emotional valence and intensity, based solely on non-verbal vocal bursts that are also common in other mammals. It is not known, however, whether human listeners rely on similar acoustic cues to assess emotional content in conspecific and heterospecific vocalizations, and which acoustical parameters affect their performance. Here, for the first time, we directly compared the emotional valence and intensity perception of dog and human non-verbal vocalizations. We revealed similar relationships between acoustic features and emotional valence and intensity ratings of human and dog vocalizations: those with shorter call lengths were rated as more positive, whereas those with a higher pitch were rated as more intense. Our findings demonstrate that humans rate conspecific emotional vocalizations along basic acoustic rules, and that they apply similar rules when processing dog vocal expressions. This suggests that humans may utilize similar mental mechanisms for recognizing human and heterospecific vocal emotions.

    2015-11-01

    The evidence that supports the preventive effect of combination antiretroviral treatment (cART) in HIV sexual transmission suggested the so-called 'treatment as prevention' (TAP) strategy as a promising tool for slowing down HIV transmission. As the messages and attitudes towards condom use in the context of TAP appear to be somehow confusing, the aim here is to assess whether relying on cART alone to prevent HIV transmission can currently be recommended from the Public Health perspective. A review is made of the literature on the effects of TAP strategy on HIV transmission and the epidemiology of other sexual transmitted infections (STIs) in the cART era, and recommendations from Public Health institutions on the TAP as of February 2014. The evolution of HIV and other STIs in Barcelona from 2007 to 2012 has also been analysed. Given that the widespread use of cART has coincided with an increasing incidence of HIV and other STIs, mainly amongst men who have sex with men, a combination and diversified prevention methods should always be considered and recommended in counselling. An informed decision on whether to stop using condoms should only be made by partners within stable couples, and after receiving all the up-to-date information regarding TAP. From the public health perspective, primary prevention should be a priority; therefore relying on cART alone is not a sufficient strategy to prevent new HIV and other STIs.

  18. Energy and environmental consciousness. Differences between advanced and developing countries

    Takeshita, Takashi

    1999-01-01

    The purpose of the present study is to understand how much differences there are between advanced countries and developing countries in terms of environmental and energy consciousness. We are experiencing now a big dilemma of the human desire to continue to exist and, at the same time, to develop the economy against the worsening of the Earth's environmental conditions. Understanding international differences of environmental and energy consciousness is a short way to solve this dilemma. The results of the present study were that peoples from advanced countries feel that science and technology are sometimes unreliable, while those from developing countries, are willing to rely upon them. However regardless of the country, people share the same consciousness about Earth's environment. In both, advanced and developing countries, people are reluctant to give up living comforts, unless this leads to a higher standard of living. Based on this result, the author would like to conduct another survey concerning the consciousness of future lifestyle. (author)

  19. Social plasticity relies on different neuroplasticity mechanisms across the brain social decision-making network in zebrafish

    Full Text Available Social living animals need to adjust the expression of their behavior to their status within the group and to changes in social context and this ability (social plasticity has an impact on their Darwinian fitness. At the proximate level social plasticity must rely on neuroplasticity in the brain social decision-making network (SDMN that underlies the expression of social behavior, such that the same neural circuit may underlie the expression of different behaviors depending on social context. Here we tested this hypothesis in zebrafish by characterizing the gene expression response in the SDMN to changes in social status of a set of genes involved in different types of neural plasticity: bdnf, involved in changes in synaptic strength; npas4, involved in contextual learning and dependent establishment of GABAergic synapses; neuroligins (nlgn1 and nlgn2 as synaptogenesis markers; and genes involved in adult neurogenesis (wnt3 and neurod. Four social phenotypes were experimentally induced: Winners and Losers of a real-opponent interaction; Mirror-fighters, that fight their own image in a mirror and thus do not experience a change in social status despite the expression of aggressive behavior; and non-interacting fish, which were used as a reference group. Our results show that each social phenotype (i.e. Winners, Losers and Mirror-fighters present specific patterns of gene expression across the SDMN, and that different neuroplasticity genes are differentially expressed in different nodes of the network (e.g. BDNF in the dorsolateral telencephalon, which is a putative teleost homologue of the mammalian hippocampus.

    Optimal blood folate levels of women before pregnancy are critical to the prevention of neural tube defects (NTDs). However, few studies have focused on blood folate levels of women planning to become pregnant. The aims of this study were to assess plasma folate levels in women who planned to become pregnant in a population with high prevalence of NTDs, to identify factors associated with plasma folate levels, and to evaluate the risk of NTDs at the population level. A total of 2065 women were enrolled at the time of premarital health check-up in two rural counties in northern China from November 2009 to December 2012. Fasting venous blood samples were collected and plasma folate concentrations were measured by microbiological method. The overall median of plasma folate was 10.5 nmol/L. 50% of the women had a plasma folate level below 10.5 nmol/L, a cutoff for megaloblastic anemia, and 88% below 18 nmol/L, a proposed optimal plasma folate level for the prevention of NTDs. Folic acid supplementation was the only factor to be associated with plasma folate concentrations, but only 1.9% of the women reported having taken folic acid supplements. A population risk of 29.3 NTD cases per 10,000 births was predicted. Women who planned to become pregnant had very low plasma folate in the population. Folic acid supplementation was the only factor to be associated with a high plasma folate concentration. High NTD risk would remain if women would get pregnant without having taken folic acid supplements.

    The screening Rose Bengal test (RBT), the buffered plate agglutination test (BPAT), and the confirmatory complement fixation test (CFT) are currently approved by the World Organization for Animal Health (OIE) for diagnosis of goat brucellosis. However, RBT (at 3% or 8% cell concentration) is known to be affected by vaccinal antibodies. In the present study, Mexican and Canadian OIE tests were compared with the fluorescence polarization assay (FPA), alone or in combination, using indirect and competitive enzyme-linked immunosorbent assays as classification variables for goat sera obtained from an area of high prevalence and widespread vaccination. The relative sensitivities and specificities were, respectively, 99.7% and 32.5% for RBT3, 92.8% and 68.8% for RBT8, 98.4% and 84.8% for Canadian CFT, 83.7% and 65.5% for Mexican CFT, and 78.1% and 89.3% for FPA. The use of FPA as the confirmatory test in combination with other tests significantly increased the final specificities of the screening tests alone; BPAT, RBT3, and RBT8 plus FPA resulted in final specificities of 90%, 91.2%, and 91.3%, respectively, whereas for the combinations RBT3 plus Mexican CFT, RBT8 plus Mexican CFT, and BPAT plus Canadian CFT, specificities were 65.5%, 63.2%, and 91.7%, respectively. We suggest that FPA may be routinely applied as an adaptable screening test for diagnosis of goat brucellosis and as a confirmatory test for screening test series. Some advantages of FPA are that its cutoff can be adjusted to improve its sensitivity or specificity, it is a low-cost and easy-to-perform test of choice when specificity is relevant or when an alternative confirmatory test is not available, and it is not affected by vaccination, thus reducing the number of misdiagnosed and killed goats.

    Previous studies have suggested a higher prevalence of intracranial aneurysms (IAs) in patients with aortic aneurysms (AAs). To carry out a preliminary study to evaluate the prevalence of IAs in these patients and the diagnostic feasibility of extended aorta CT angiography (CTA), including intracranial arteries as well as the aorta. We retrospectively reviewed all patients with a clinical diagnosis of AA or aortic dissection (AD) who had undergone aorta CTA as well as MR angiography, CTA, and/or DSA of the brain between 2009 and 2014. Since 2012, the extended aorta CTA protocol has been applied in these patients. Characteristics of IAs were classified with baseline clinical data. For quantitative and qualitative assessment by two independent raters, brain images obtained by extended aorta CTA and brain CTA were compared. The radiation dose of the two aorta protocols was compared. The prevalence of IA was 22.2% (35/158). All IAs were detected by extended aorta CTA, except one small aneurysm (product of the extended aorta CTA increased with increment of the scan range (p=0.048). With a high prevalence of IAs in patients with ADs or AAs, extended aorta CTA could be used to evaluate aorta disease and IA in a single session. However, further prospective studies are needed to prove efficacy and safety of the extended aorta CTA protocol in patients with AAs or ADs. Published by the BMJ Publishing Group Limited.

    To find out the prevalence of hyperhomocysteinemia, and deficiencies of folate, vitamin B6 and vitamin B12 in an urban population in Karachi, Pakistan. Methodology: In a pre and post experimental study, eight hundred and seventy-two apparently healthy adults (aged 18-60 years; 355 males and 517 females) were recruited from a low-income urban locality in East of Karachi from February 2006 to March 2007. Fasting venous blood was obtained. Serum was analyzed for folate and vitamin B12. Plasma was analyzed for pyridoxal phosphate (PLP, co enzymic form of B6) and total homocysteine. A group of vitamin-deficient individuals (n=194) was given 3-week supplementation with folic acid (5mg/ day), methylcobalamin (0.5mg/day) and pyridoxine hydrochloride (vitamin B6, 50 mg/day). After supplementation, serum/plasma levels of folate, vitamin B12, PLP and homocysteine were again determined. Prevalence of hyperhomocysteinemia (>15 mu mol/l) was 32%. Similarly percent values of folate deficiency (<3.5ng/ml), vitamin B6 deficiency (PLP<20 nmol/l) and vitamin B12 deficiency (<200pg/ml) in the study population were 27.5%, 33.7% and 9.74%, respectively. Hyperhomocysteinemia was associated with male sex, folate deficiency, vitamin B12 deficiency [OR (95%CI), 8.3(5.7-12.1); 2.5(1.76-3.58); 2.6(1.5-4.5), respectively]. A 3-week supplementation with folic acid, methylcobalamin and pyridoxine hydrochloride in vitamin deficient subjects decreased plasma homocysteine levels by 37%. High prevalence estimates of folate, vitamin B12, and vitamin B6 deficiencies appear to be the major determinants of hyperhomocysteinemia in a low income general population in Karachi. (author)

    Polycystic ovary syndrome (PCOS) is more frequently observed in type 1 diabetes mellitus (T1DM) adult women than in nondiabetic women. No such prevalence has yet been studied in adolescent girls with T1DM. The aim of this study was to evaluate the prevalence of PCOS in adolescent girls with T1DM and to determine the clinical and hormonal features associated with the disorder. A cross-sectional study of 53 adolescent girls (gynecological age >2 years) referred for routine evaluation for T1DM was conducted. We diagnosed PCOS using the National Institutes of Health (NIH) and Rotterdam criteria. 26.4 and 47.9% of adolescents had PCOS according to NIH (NIH-PCOS) and Rotterdam (Rotterdam-PCOS) criteria. 66.7% of NIH-PCOS adolescents had a complete phenotype associated with hyperandrogenism, oligomenorrhea, and polycystic ovarian morphology, unlike only 33.3% of the Rotterdam-PCOS adolescents. A family history of type 2 diabetes mellitus (T2DM) was more frequent in PCOS than in non-PCOS girls, whichever criteria were used. Late pubertal development and a T1DM diagnosis close to puberty were factors associated with NIH-PCOS. Adolescents with T1DM had a high prevalence of PCOS. More differences between PCOS and non-PCOS patients were found using the NIH criteria, suggesting that clinical characteristics might be more accurate for diagnosing PCOS in girls with T1DM. A family history of T2DM is associated with a high risk of PCOS. © 2017 S. Karger AG, Basel.

    Fantahun Biadglegne

    Full Text Available BACKGROUND: Tuberculosis (TB transmission in prisons poses significant risks to inmates as well as the general population. Currently, there are no data on smear-negative pulmonary TB cases in prisons and by extension no data on the impact such cases have on TB incidence. This study was designed to obtain initial data on the prevalence of smear-negative cases of TB in prisons as well as preliminary risk factor analysis for such TB cases. METHODS: This cross-sectional survey was conducted in November 2013 at eight main prisons located in the state of Amhara, Ethiopia. Interviews using a structured and pretested questionnaire were done first to identify symptomatic prisoners. Three consecutive sputum samples were collected and examined using acid fast bacilli (AFB microscopy at the point of care. All smear-negative sputum samples were taken for culture and Xpert testing. Descriptive and multivariate analysis was done using SPSS version 16. RESULTS: Overall the prevalence of smear-negative pulmonary TB cases in the study prisons was 8% (16/200. Using multivariate analysis, a contact history to TB patients in prison, educational level, cough and night sweating were found to be predictors of TB positivity among smear-negative pulmonary TB cases (p ≤ 0.05. CONCLUSIONS: In the studied prisons, high prevalence of undiagnosed TB cases using AFB microscopy was documented, which is an important public health concern that urgently needs to be addressed. Furthermore, patients with night sweating, non-productive cough, a contact history with TB patients and who are illiterate merit special attention, larger studies are warranted in the future to assess the associations more precisely. Further studies are also needed to examine TB transmission dynamics by patients with smear-negative pulmonary TB in a prison setting.

    Full Text Available Abstract Background Vitamin D status, as indicated by 25-hydroxyvitamin D is inversely associated with adiposity, glucose homeostasis, lipid profiles, and blood pressure along with its classic role in calcium homeostasis and bone metabolism. It is also shown to be inversely associated with metabolic syndrome and cardiovascular diseases in western populations. However, evidence from the Asian population is limited. Therefore, we aim to study the prevalence of vitamin D insufficiency ( Methods This is an analytical cross sectional study. A total of 380 subjects were sampled and their vitamins D status (25-hydroxyvitamin D, fasting blood glucose, full lipid profile were assessed using venous blood. Systolic and diastolic blood pressure, weight, height and waist circumference were measured following standard protocols. Socio-demographic data such as sex, age, smoking status etc were also collected. Data was analysed using t-test, chi-square test, General Linear Model and multiple logistic regression. Results Females made up 58% of the sample. The mean age of respondents was 48.5 (SD 5.2 years. Females had significantly lower mean Vitamin D levels (36.2; 95% CI: 34.5, 38.0 nmol/L compared to males (56.2; 95% CI: 53.2, 59.2 nmol/L. Approximately 41% and 87% of males and females respectively had insufficient ( Conclusions Our results highlight the high prevalence of vitamin D insufficiency among Malay adults in Kuala Lumpur. Vitamin D insufficiency is independently associated with younger age, female sex and greater abdominal obesity. Vitamin D insufficiency is also associated with Metabolic Syndrome.

  9. High prevalence and associated risk factors for impaired renal function and urinary abnormalities in a rural adult population from southern China.

    Qinghua Liu

    Full Text Available BACKGROUND: The prevalence of chronic kidney disease (CKD has increased and will continue to rise worldwide. However, data regarding the prevalence of CKD in a rural area of China are limited. We therefore investigated the prevalence and associated risk factors of impaired renal function and urinary abnormalities in an adult rural population in southern China. METHODS: Between December 2006 and January 2007, residents older than 20 years from four villages in Zhuhai city were randomly selected using a stratified, multistage sampling technique. All participants were interviewed and tested for hematuria, albuminuria and estimated glomerular filtration rate (eGFR. The associations between age, gender, diabetes mellitus, hypertension, hyperuricemia, education level and indicators of renal damage were examined. RESULTS: Overall, 1,214 subjects were enrolled in this study. After adjustment for age and gender, the prevalence of albuminuria was 7.1% (95% CI: 4.5, 8.1, reduced eGFR was 2.6% (95% CI: 1.7%, 3.3%, and hematuria was 4.6% (95% CI: 3.3%, 6.0%. Approximately 13.6% (95% CI: 12.0%, 15.1% of the patients had at least one indicator of renal damage, but only 8.3% were previously aware. Age, diabetes, hyperlipidemia, hypertension, hyperuricemia, use of nephrotoxic medications, coronary heart disease and history of CKD were independently associated with impaired renal function and urinary abnormalities. Additionally, age, diabetes, and hypertension were independently associated with albuminuria. Age, hypertension, hyperuricemia, central obesity, and coronary heart disease were independently associated with reduced renal function. CONCLUSIONS: The high prevalence and low awareness of impaired renal function and urinary abnormalities in this population illustrates the urgent need to implement a CKD prevention program in the rural areas of southern China.

    Alaska Native colorectal cancer (CRC) incidence and mortality rates are the highest of any ethnic/racial group in the United States. CRC screening using guaiac-based fecal occult blood tests (gFOBT) are not recommended for Alaska Native people because of false-positive results associated with a high prevalence of Helicobacter pylori-associated hemorrhagic gastritis. This study evaluated whether the newer immunochemical FOBT (iFOBT) resulted in a lower false-positive rate and higher specificity for detecting advanced colorectal neoplasia than gFOBT in a population with elevated prevalence of H. pylori infection. We used a population-based sample of 304 asymptomatic Alaska Native adults aged 40 years or older undergoing screening or surveillance colonoscopy (April 2008-January 2012). Specificity differed significantly (P < .001) between gFOBT (76%; 95% CI, 71%-81%) and iFOBT (92%; 95% CI, 89%-96%). Among H. pylori-positive participants (54%), specificity of iFOBT was even higher (93% vs 69%). Overall, sensitivity did not differ significantly (P = .73) between gFOBT (29%) and iFOBT (36%). Positive predictive value was 11% for gFOBT and 32% for iFOBT. The iFOBT had a significantly higher specificity than gFOBT, especially in participants with current H. pylori infection. The iFOBT represents a potential strategy for expanding CRC screening among Alaska Native and other populations with elevated prevalence of H. pylori, especially where access to screening endoscopy is limited.

    To compare visual acuity results obtained by use of the Lea Symbols chart with results obtained with Early Treatment Diabetic Retinopathy Study (ETDRS) charts in young children who are members of a population with a high prevalence of astigmatism. Subjects were 438 children ages 5 through 7 years who were enrolled in kindergarten or first grade on the Tohono O'odham Reservation: 241 (55%) had astigmatism >or=1.00 D in one or both eyes (range, 0.00-6.75 D). While wearing best correction, each child had right eye visual acuity tested with the 62 cm by 65 cm Lea Symbols chart at 3 m and with the 62 cm by 65 cm ETDRS chart at 4 m. Visual acuity was scored as the smallest optotype size at which the child correctly identified 3 of a maximum of 5 optotypes. ETDRS visual acuity also was scored based on the total number of letters that the child correctly identified. Correlation between Lea Symbols visual acuity and ETDRS visual acuity was 0.78 (p < 0.001). Mean Lea Symbols visual acuity was one-half line (0.04-0.06 logMAR) better than mean ETDRS visual acuity (p < 0.001). The difference between Lea Symbols and ETDRS visual acuity was not correlated with the mean of the Lea Symbols and ETDRS visual acuity scores, which ranged from -0.3 logMAR (20/10) to 0.74 logMAR (20/110). In this population of young children, in whom the primary source of reduced visual acuity is astigmatism-related amblyopia, the Lea Symbols chart produced visual acuity scores that were about 0.5 line better than visual acuity scores obtained with ETDRS charts.

    Highlights: •Secretin improved visualization of ductal communication of a cystic pancreatic lesion. •No association between cysts and gender, ethnicity or type of high risk. •Incremental value of secretin could offset the added cost and time. -- Abstract: Purpose: We investigated the incremental diagnostic yield of S-MRCP in a population with high prevalence of small pancreatic cysts. Methods: Standard MRCP protocol was performed with and without secretin using 1.5 T units in subjects undergoing pancreatic screening because of a strong family history of pancreatic cancer as part of the multicenter Cancer of the Pancreas Screening-3 trial (CAPS 3). All studies were reviewed prospectively by two independent readers who recorded the presence and number of pancreatic cysts, the presence of visualized ductal communication before and after secretin, and the degree of confidence in the diagnoses. Result: Of 202 individuals enrolled (mean age 56 years, 46% males), 93 (46%) had pancreatic cysts detected by MRCP, and 64 of the 93 had pre-and post-secretin MRCP images available for comparison. Data from the 128 readings show that 6 (6/128 = 4.7%) had ductal communication visualized only on the secretin studies compared to pre-secretin studies (odds ratio 1.28, p = 0.04). In addition, there was a statistically significant increase in confidence in reporting ductal communication after secretin compared to before secretin (p < 0.0005). Conclusion: At 1.5 T MRI, the use of secretin can improve the visualization of ductal communication of cystic pancreatic lesions.

    Evaluation of causal abnormalities identified on CT and MR imaging in children with unilateral sensorineural hearing loss (USNHL), and the association with age and severity of hearing loss. Retrospective cohort study. Tertiary referral otology/audiology center. 102 children diagnosed with USNHL between 2006 and 2016 were included. They underwent CT and/or MR imaging for the evaluation of the etiology of their hearing loss. Radiologic abnormalities of the inner ear and brain associated with USNHL. Using CT and/or MR imaging, causal abnormalities were identified in 49%, which is higher than previously reported (25-40%). The most frequently affected site was the labyrinth (29%), followed by the cochlear nerve (9%) and brain (7%). No significant difference in the number or type of abnormalities was found for the degree of hearing loss or age categories. Imaging is essential in the etiologic analysis of USNHL because of the high prevalence of causative abnormalities that can be identified with radiology, irrespective of the patients' age or degree of hearing loss. CT and MR imaging are complementary imaging options. The ideal imaging algorithm is controversial. Based on our findings, we conclude that there is limited additional diagnostic value of simultaneous dual modality imaging over sequential diagnostics. We therefore perform a stepwise radiological workup in order to maximize the diagnostic yield while minimizing impact and costs. If the primary imaging modality does not identify a cause for USNHL, performing the alternative imaging modality should be considered. Retrospective cohort study 2b. Copyright © 2017 Elsevier B.V.

    In this prospective cohort study, we investigated the prevalence of diabetic peripheral neuropathy at baseline and after five years of follow-up in children and adolescents with type 1 diabetes mellitus using both measurements of nerve conduction velocity and clinical neurological examination. A total of 38 patients who underwent insulin pump or intensive insulin therapy were included. The subjects averaged 12.6 ± 2.4 years of age and their diabetes duration averaged 5.6 ± 3.2 years. All patients underwent a detailed physical, neurological, and electrophysiological examination, as well as laboratory testing at their annual checkup. At baseline, the prevalence of diabetic peripheral neuropathy diagnosed using neurological examination was 13.2%, whereas nerve conduction velocity testing revealed diabetic peripheral neuropathy in 31.6%, highlighting a high prevalence of subclinical diabetic peripheral neuropathy. During follow-up, there was a strong increase in the prevalence of clinically diagnosed diabetic peripheral neuropathy, which reached 34.2% (P = 0.039) after five years; the proportion of patients with subclinical diabetic peripheral neuropathy even reached 63.2% (P = 0.002). The most significant changes in electrophysiological parameters were observed in the tibial sensory nerve (P = 0.001). The prevalence of diabetic peripheral neuropathy in children and adolescents with type 1 diabetes mellitus was high, and there was a rapid increase in the prevalence of diabetic peripheral neuropathy during a five-year follow-up interval. Importantly, our data show that a mere clinical evaluation is not sensitive enough to diagnose diabetic peripheral neuropathy in these patients. Nerve conduction velocity measurement, which is regarded as the gold standard for the assessment of diabetic peripheral neuropathy, should be applied more broadly. Copyright © 2017 Elsevier Inc.

    Full Text Available Adult community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA and methicillin-susceptible S. aureus (CA-MSSA skin and soft tissue infection (SSTI in China is not well described. A prospective cohort of adults with SSTI was established between January 2009 and August 2010 at 4 hospitals in Beijing. Susceptibility testing and molecular typing, including multilocus sequence typing, spa, agr typing, and toxin detection were assessed for all S. aureus isolates. Overall, 501 SSTI patients were enrolled. Cutaneous abscess (40.7% was the most common infection, followed by impetigo (6.8% and cellulitis (4.8%. S. aureus accounted for 32.7% (164/501 of SSTIs. Five isolates (5/164, 3.0% were CA-MRSA. The most dominant ST in CA-MSSA was ST398 (17.6%. The prevalence of Panton-Valentine Leukocidin (pvl gene was 41.5% (66/159 in MSSA. Female, younger patients and infections requiring incision or drainage were more commonly associated with pvl-positive S. aureus (P<0.03; sec gene was more often identified in CC5 (P<0.03; seh gene was more prevalent in CC1 (P = 0.001. Importantly, ST59 isolates showed more resistance to erythromycin, clindamycin and tetracycline, and needed more surgical intervention. In conclusion, CA-MRSA infections were rare among adult SSTI patients in Beijing. Six major MSSA clones were identified and associated with unique antimicrobial susceptibility, toxin profiles, and agr types. A high prevalence of livestock ST398 clone (17.1% of all S. aureus infections was found with no apparent association to animal contact.

    2013-01-01

    Background Hepatitis D virus (HDV) infection is considered to cause more severe hepatitis than hepatitis B virus (HBV) monoinfection. With more than 9.5 million HBV-infected people, Vietnam will face an enormous health burden. The prevalence of HDV in Vietnamese HBsAg-positive patients is speculative. Therefore, we assessed the prevalence of HDV in Vietnamese patients, determined the HDV-genotype distribution and compared the findings with the clinical outcome. Methods 266 sera of well-characterized HBsAg-positive patients in Northern Vietnam were analysed for the presence of HDV using newly developed HDV-specific RT-PCRs. Sequencing and phylogenetic analysis were performed for HDV-genotyping. Results The HDV-genome prevalence observed in the Vietnamese HBsAg-positive patients was high with 15.4% while patients with acute hepatitis showed 43.3%. Phylogenetic analysis demonstrated a predominance of HDV-genotype 1 clustering in an Asian clade while HDV-genotype 2 could be also detected. The serum aminotransferase levels (AST, ALT) as well as total and direct bilirubin were significantly elevated in HDV-positive individuals (p<0.05). HDV loads were mainly low (<300 to 4.108 HDV-copies/ml). Of note, higher HDV loads were mainly found in HBV-genotype mix samples in contrast to single HBV-infections. In HBV/HDV-coinfections, HBV loads were significantly higher in HBV-genotype C in comparison to HBV-genotype A samples (p<0.05). Conclusion HDV prevalence is high in Vietnamese individuals, especially in patients with acute hepatitis B. HDV replication activity showed a HBV-genotype dependency and could be associated with elevated liver parameters. Besides serological assays molecular tests are recommended for diagnosis of HDV. Finally, the high prevalence of HBV and HDV prompts the urgent need for HBV-vaccination coverage. PMID:24205106

    To analyze the clinical and genetic characteristics of Chinese patients with pyridox(am)ine-5'-phosphate oxidase (PNPO) deficiency. The clinical presentations and the responses to treatments were analyzed in 4 patients. Blood and urinary metabolic screenings, electroencephalogram (EEG), brain magnetic resonance imaging (MRI) and epilepsy-related genes detection were performed in all patients. Patient 1 and 2 were identical twin brothers, who were born at 35 +5 w gestation with a sign of encephalopathy. Their seizures started within the first day and could not be controlled by pyridoxine or pyridoxal-5'-phosphate (PLP) completely. Patient 3 presented seizures at 5 months, responding well to pyridoxine. Seizures in patient 4 began at 40 days after birth and were controlled by valproic acid and topiramate. EEG showed atypical hypsarrhythmia or multifocal epileptiform discharges in 3 patients, and showed normality in patient 4. MRI showed nonspecific abnormality or normality. Blood metabolic screening showed multiple amino acids level abnormalities in all cases. Urinary metabolic screening showed vanillactic acid prominently elevated in 3 patients. Genetic analysis revealed 5 mutations of PNPO, three of which were novel. The mutation c.445_448del was carried by the twins and patient 3. Assessment of psychomotor development indicated severe delay in 3 patients and borderline to mild delay in patient 3. This is the first time to report patients with PNPO deficiency diagnosed by gene analysis in China. The novel clinical characteristics and novel mutations found here expanded the phenotypes and genotypes of this disease. Further, the frameshift mutation c.445_448del might be high prevalence in PNPO deficiency in Chinese patients.

    The genus Circovirus includes one of the most relevant infectious agents affecting domestic pigs, Porcine circovirus type 2 (PCV-2). The wild boar susceptibility to this pathogen has also been demonstrated although the actual epidemiological role of wild populations is still debated. In recent times, a new circovirus, Porcine circovirus type 3 (PCV-3), has been discovered and reported in the presence of several clinical conditions. However, no information is currently available about PCV-3 circulation and prevalence in wild boar. To fill this gap, 187 wild boar serum samples were collected in the Colli Euganei Regional Park (Northern Italy) and screened for PCV-3, demonstrating a high viral prevalence (approximately 30%). No gender differences were demonstrated while a lower infection prevalence was observed in animals younger than 12 months compared to older ones, differently from what described in commercial pigs. Almost all sampled animals were in good health conditions and no association was proven between PCV-3 status and clinical syndromes in wild animals. The genetic characterization of selected strains enlightened a relevant variability and the absence of closely related strains originating from domestic pigs. Therefore, the observed scenario is suggestive of multiple introductions from other wild or domestic swine populations followed by prolonged circulation and independent evolution. Worldwide, this study reports for the first time the high susceptibility of the wild boar to PCV-3 infection. The high prevalence and the absence of association with clinical signs support the marginal role of this virus in the wild boar population ecology. However, its epidemiological role as reservoir endangering commercial swine cannot be excluded and will require further investigations. © 2018 Blackwell Verlag GmbH.

    Like Many African countries, Uganda is not Immune to the problem of illicit trafficking of Nuclear and Radioactive materials. This has been worsened by the porosity of the Ugandan Borders. There is control on the few Entry points and much of the border line does not have adequate control on what enters and leaves the country. Uganda is also used as a transit route with the neighboring countries like Sudan, Democratic Republic of Congo, Kenya,Tanzania.

    Spelling is an important skill for individuals who rely on augmentative and alternative communication (AAC). The purpose of this study was to investigate how computerized sounding out influenced spelling accuracy of pseudo-words. Computerized sounding out was defined as a word elongated, thus providing an opportunity for a child to hear all the sounds in the word at a slower rate. Seven children with cerebral palsy, four who use AAC and three who do not, participated in a single subject AB design. The results of the study indicated that the use of computerized sounding out increased the phonologic accuracy of the pseudo-words produced by participants. The study provides preliminary evidence for the use of computerized sounding out during spelling tasks for children with cerebral palsy who do and do not use AAC. Future directions and clinical implications are discussed. We investigated how computerized sounding out influenced spelling accuracy of pseudowords for children with complex communication needs who did and did not use augmentative and alternative communication (AAC). Results indicated that the use of computerized sounding out increased the phonologic accuracy of the pseudo-words by participants, suggesting that computerized sounding out might assist in more accurate spelling for children who use AAC. Future research is needed to determine how language and reading abilities influence the use of computerized sounding out with children who have a range of speech intelligibility abilities and do and do not use AAC.

  2. Catalytic ozonation not relying on hydroxyl radical oxidation: A selective and competitive reaction process related to metal-carboxylate complexes

    Zhang, Tao

    2014-01-01

    Catalytic ozonation following non-hydroxyl radical pathway is an important technique not only to degrade refractory carboxylic-containing organic compounds/matter but also to avoid catalyst deactivation caused by metal-carboxylate complexation. It is unknown whether this process is effective for all carboxylates or selective to special molecule structures. In this work, the selectivity was confirmed using O3/(CuO/CeO2) and six distinct ozone-resistant probe carboxylates (i.e., acetate, citrate, malonate, oxalate, pyruvate and succinate). Among these probe compounds, pyruvate, oxalate, and citrate were readily degraded following the rate order of oxalate>citrate>pyruvate, while the degradation of acetate, malonate, and succinate was not promoted. The selectivity was independent on carboxylate group number of the probe compounds and solution pH. Competitive degradation was observed for carboxylate mixtures following the preference order of citrate, oxalate, and finally pyruvate. The competitive degradation was ascribed to competitive adsorption on the catalyst surface. It was revealed that the catalytically degradable compounds formed bidentate chelating or bridging complexes with surface copper sites of the catalyst, i.e., the active sites. The catalytically undegradable carboxylates formed monodentate complexes with surface copper sites or just electrostatically adsorbed on the catalyst surface. The selectivity, relying on the structure of surface metal-carboxylate complex, should be considered in the design of catalytic ozonation process. © 2013 Elsevier B.V.

  3. Spatial Reorganization of the Endoplasmic Reticulum during Mitosis Relies on Mitotic Kinase Cyclin A in the Early Drosophila Embryo

    Bergman, Zane J.; Mclaurin, Justin D.; Eritano, Anthony S.; Johnson, Brittany M.; Sims, Amanda Q.; Riggs, Blake

    Mitotic cyclin-dependent kinase with their cyclin partners (cyclin:Cdks) are the master regulators of cell cycle progression responsible for regulating a host of activities during mitosis. Nuclear mitotic events, including chromosome condensation and segregation have been directly linked to Cdk activity. However, the regulation and timing of cytoplasmic mitotic events by cyclin:Cdks is poorly understood. In order to examine these mitotic cytoplasmic events, we looked at the dramatic changes in the endoplasmic reticulum (ER) during mitosis in the early Drosophila embryo. The dynamic changes of the ER can be arrested in an interphase state by inhibition of either DNA or protein synthesis. Here we show that this block can be alleviated by micro-injection of Cyclin A (CycA) in which defined mitotic ER clusters gathered at the spindle poles. Conversely, micro-injection of Cyclin B (CycB) did not affect spatial reorganization of the ER, suggesting CycA possesses the ability to initiate mitotic ER events in the cytoplasm. Additionally, RNAi-mediated simultaneous inhibition of all 3 mitotic cyclins (A, B and B3) blocked spatial reorganization of the ER. Our results suggest that mitotic ER reorganization events rely on CycA and that control and timing of nuclear and cytoplasmic events during mitosis may be defined by release of CycA from the nucleus as a consequence of breakdown of the nuclear envelope.

    Full Text Available Social system based on mutual trust among members continues to exist. Social trust in modem era is more important than earlier periods. Subject of current report is focused on the trust of Iranian students in different aspects. Main question in this investigation is about social-political trust of these students (based on trust in Islamic Republic of Iran at the past and present. This matter explored by secondary analysis of data, Relying on secondary analysis of some national surveys. Based on data and consequences of other researches we are going to illustrate the objective aspects of student's trust in current decades. The main sources for data collection at this stage include: All the public surveys conducted in the past four decades, the general data about students and their related assays. Trust students were evaluated on the following dimensions: trust in trade unions and various groups, trust in the clergy, directors of public trust and confidence in judges. Furthermore, the level of political engagement and participation in elections, satisfaction with economic situation, political situation and level of satisfaction with confidence in radio and television news. Reduction of public trust leads to reduced maximum student trust especially in the social and political dimensions.

    Bonemei, Rob; Costantino, Andrea I; Battistel, Ilenia; Rivolta, Davide

    2018-05-01

    Faces and bodies are more difficult to perceive when presented inverted than when presented upright (i.e., stimulus inversion effect), an effect that has been attributed to the disruption of holistic processing. The features that can trigger holistic processing in faces and bodies, however, still remain elusive. In this study, using a sequential matching task, we tested whether stimulus inversion affects various categories of visual stimuli: faces, faceless heads, faceless heads in body context, headless bodies naked, whole bodies naked, headless bodies clothed, and whole bodies clothed. Both accuracy and inversion efficiency score results show inversion effects for all categories but for clothed bodies (with and without heads). In addition, the magnitude of the inversion effect for face, naked body, and faceless heads was similar. Our findings demonstrate that the perception of faces, faceless heads, and naked bodies relies on holistic processing. Clothed bodies (with and without heads), on the other side, may trigger clothes-sensitive rather than body-sensitive perceptual mechanisms. © 2017 The British Psychological Society.

    It has been hypothesized that dietary creatine could influence cognitive performance by increasing brain creatine in developing individuals. This double-blind, randomized, placebo-controlled, proof-of-principle study aimed to investigate the effects of creatine supplementation on cognitive function and brain creatine content in healthy youth. The sample comprised 67 healthy participants aged 10 to 12 years. The participants were given creatine or placebo supplementation for 7 days. At baseline and after the intervention, participants undertook a battery of cognitive tests. In a random subsample of participants, brain creatine content was also assessed in the regions of left dorsolateral prefrontal cortex, left hippocampus, and occipital lobe by proton magnetic resonance spectroscopy (1H-MRS) technique. The scores obtained from verbal learning and executive functions tests did not significantly differ between groups at baseline or after the intervention (all p > 0.05). Creatine content was not significantly different between groups in left dorsolateral prefrontal cortex, left hippocampus, and occipital lobe (all p > 0.05). In conclusion, a 7-day creatine supplementation protocol did not elicit improvements in brain creatine content or cognitive performance in healthy youth, suggesting that this population mainly relies on brain creatine synthesis rather than exogenous creatine intake to maintain brain creatine homeostasis.

  7. Symmetric Encryption Relying on Chaotic Henon System for Secure Hardware-Friendly Wireless Communication of Implantable Medical Systems

    2018-05-01

    Full Text Available Healthcare remote devices are recognized as a promising technology for treating health related issues. Among them are the wireless Implantable Medical Devices (IMDs: These electronic devices are manufactured to treat, monitor, support or replace defected vital organs while being implanted in the human body. Thus, they play a critical role in healing and even saving lives. Current IMDs research trends concentrate on their medical reliability. However, deploying wireless technology in such applications without considering security measures may offer adversaries an easy way to compromise them. With the aim to secure these devices, we explore a new scheme that creates symmetric encryption keys to encrypt the wireless communication portion. We will rely on chaotic systems to obtain a synchronized Pseudo-Random key. The latter will be generated separately in the system in such a way that avoids a wireless key exchange, thus protecting patients from the key theft. Once the key is defined, a simple encryption system that we propose in this paper will be used. We analyze the performance of this system from a cryptographic point of view to ensure that it offers a better safety and protection for patients.

  13. Telemedicine for Developing Countries

    Combi, Carlo; Pozzani, Gabriele

    2016-01-01

    Summary Background Developing countries need telemedicine applications that help in many situations, when physicians are a small number with respect to the population, when specialized physicians are not available, when patients and physicians in rural villages need assistance in the delivery of health care. Moreover, the requirements of telemedicine applications for developing countries are somewhat more demanding than for developed countries. Indeed, further social, organizational, and technical aspects need to be considered for successful telemedicine applications in developing countries. Objective We consider all the major projects in telemedicine, devoted to developing countries, as described by the proper scientific literature. On the basis of such literature, we want to define a specific taxonomy that allows a proper classification and a fast overview of telemedicine projects in developing countries. Moreover, by considering both the literature and some recent direct experiences, we want to complete such overview by discussing some design issues to be taken into consideration when developing telemedicine software systems. Methods We considered and reviewed the major conferences and journals in depth, and looked for reports on the telemedicine projects. Results We provide the reader with a survey of the main projects and systems, from which we derived a taxonomy of features of telemedicine systems for developing countries. We also propose and discuss some classification criteria for design issues, based on the lessons learned in this research area. Conclusions We highlight some challenges and recommendations to be considered when designing a telemedicine system for developing countries. PMID:27803948

    Full Text Available Abstract Background Occupational Physicians rely especially on advice from colleagues when answering their information demands. On the other hand, Evidence-based Medicine (EBM promotes the use of up-to-date research literature instead of experts. To find out if there was a difference between expert-based practice and EBM we compared professional advice on occupational health topics with best evidence from the literature. Methods We asked 14 occupational physicians to consult their usual information sources on 12 pre-conceived occupational health problems. The problems were presented in the form of case vignettes which contained sufficient clinical information to be used by the occupational physicians for the consultation of their experts. We had searched the literature for the best available evidence on the 12 problems, which made it possible to answer the clinical questions with a clear yes or no. Results The cases could be used by the occupational physicians as arising from their own practice. All together the occupational physicians consulted 75 different experts. Almost half of the consulted experts were near colleagues, 10% were industrial hygienists, 8% medical specialists and the rest had a varied background. Fifty three percent (95% confidence interval 42% to 65% of all professional advice was not in line with the research literature. In 18 cases (24% professional advice explicitly referred to up-to-date research literature as their used source. These cases were substantially less incorrect (17% than advice that had not mentioned the literature as a source (65% (difference 48%, 95% Confidence Interval from 27% to 69%. Conclusion Advice that occupational physicians routinely get in their daily practice differs substantially from best evidence from the literature. Occupational physicians who ask professional advice should always ask about the evidence of this advice.

    Full Text Available Vitamin C (L-ascorbic acid or ascorbate is a biomolecule that participates in many biochemical processes. It is an essential nutrient for humans, however, in some species such as rodents and guinea pigs is synthesized. It has a variety of functions in the body that we might venture to say make it a very important antioxidant nature and pro-oxidant. L-ascorbic acidic a reduced form of vitamin C and dehydroascorbic acid (DHA is the oxidized form of ascorbate, both L-ascorbic acid and dihydroascorbic acid retain the vitamin C activity. Dehydro-ascorbate is reconverted to ascorbate in the cytosol by cytochrome b reductase and thioredoxin reductase in reactions involving NADH and NADPH, respectively. Ascorbate is transported into the cell via the sodium-dependent vitamin C transporters (SVCTs, which causes accumulation of ascorbate within cells against a concentration gradient. Dehydroascorbic acid, the oxidized form of ascorbate, is transported via glucose transporters family (GLUTs. The highest concentrations of ascorbate in the body are found in brain and adrenal gland. Vitamin C also acts as a co-factor in several enzyme reactions. This vitamin is an essential biochemical factor in the reproductive process. The pharmacophore of vitamin C is the ascorbate, ascorbate is an antioxidant.Ascorbate is a neuromodulator of glutamatergic and dopaminergic system and related behaviors. It also improves components of the immune system. Given the wide role of ascorbate, further investigation is necessary to evaluate the exact mechanism(s underlying these effects. In this review we will consider a short overview of the characteristics and function of vitamin C (relying on antioxidant function in various tissues.

  19. High Prevalence but Insufficient Treatment of Iron-Deficiency Anemia in Patients with Inflammatory Bowel Disease: Results of a Population-Based Cohort

    Ott, Claudia; Liebold, Anne; Takses, Angela; Strauch, Ulrike G.; Obermeier, Florian

    2012-01-01

    Background. Iron-deficiency anemia is described to be a common problem in patients with inflammatory bowel disease (IBD), which is frequently associated with a reduced quality of life. Therefore, the aim of this study is to assess the prevalence of iron deficiency anemia in a population-based cohort at time of first diagnosis and during the early course of the disease. Methods. As far as available, lab values of patients registered in the population-based “Oberpfalz cohort” were screened. In anemic patients, we further investigated all laboratory results to differentiate between iron deficiency and other reasons for anemia. All patients with any kind of anemia were interviewed separately according to symptoms of iron-deficiency anemia and administration of iron. Results. In total, we evaluated hemoglobin values of 279 patients (183 Crohn's disease, 90 ulcerative colitis, and 6 indeterminate colitis). Lab data which allowed further differentiation of the type of anemia were available in 70% of anemic patients, in 34.4% values of iron, ferritin and transferrin saturation had been measured. At time of first diagnosis, an iron-deficiency anemia was diagnosed in 26 of 68 patients with anemia (38.2%, 20 CD, 4 UC, and 2 IC patients), but only 9 patients (34.6%) received subsequent iron therapy. After one year, 27 patients were identified to have an iron-deficiency anemia (19 CD, 8 UC), 20 of them were treated with iron (71.4%). Of 9 patients with proven iron-deficiency anemia at time of first diagnosis and subsequent administration of iron, 5 (55.5%) had iron-deficiency anemia despite permanent treatment after one year. In total, 38 patients (54.3%) did not receive any iron substitution at all despite of proven iron-deficiency anemia, and only 13 patients of 74 patients were treated with intravenous iron (17.6%). Conclusion. We found a high prevalence of iron-deficiency anemia at different points during the early course of disease in this population-based cohort of

    Hepatitis B virus (HBV) infection may be underestimated among high-risk individuals in regions of low HBs antigenemia. This study aimed to assess HBV serological markers, genotypes, and risk factors in Mexican patients with risk of HBV infection and low socioeconomic status. Demographics, clinical, and risk factor data were collected in patients with HIV (n = 289), HCV (n = 243), deferred blood donors (D-BD) (n = 83), and two native populations, Mixtecos (n = 57) and Purepechas (n = 44). HBV infection was assessed by HBsAg, anti-HBc, and HBV-DNA testing. Overall, patients had low education and very-low income. Totally, HBsAg prevalence was 16.5% (113/684) ranging from 0.7% (HCV) to 37.3% (D-BD), while anti-HBc was 30.2% (207/684). Among 52 sequences, genotypes H (n = 34, 65.4%), G (n = 4, 7.7%), subgenotypes F1b (n = 7, 13.5%), A2 (n = 6, 11.5%), and D4 (n = 1, 1.9%) were detected. Surgeries, sexual promiscuity, and blood transfusions had a differential pattern of distribution. In HCV patients, single (OR = 5.84, 95%Cl 1.91-17.80, P = 0.002), MSM (OR = 4.80, 95%Cl 0.75-30.56, P = 0.097), and IDU (OR = 2.93, 95%CI 1.058-8.09, P = 0.039) were predictors for HBV infection. While IDU (OR = 2.68, 95%CI 1.08-6.61, P = 0.033) and MSM (OR = 2.64, 95%CI 1.39-5.04, P = 0.003) were predictors in HIV patients. In this group, MSM was associated with HBsAg positivity (OR = 3.45, 95%CI 1.48-8.07, P = 0.004) and IDU with anti-HBc positivity (OR = 5.12, 95%CI 2.05-12.77, P HBV markers, a high prevalence of HBV infection, a differential distribution of HBV genotypes, including subgenotypes F1b, A2, and D4, as well as risk factors in low-income Mexican risk groups were detected. © 2017 Wiley Periodicals, Inc.

    Full Text Available ObjectivesThis study aimed to identify and characterize extended-spectrum β-lactamase (ESBL producing Enterobacteriaceae among clinical samples of companion animals.MethodsA total of 346 non-duplicate Enterobacteriaceae isolates were collected between 2012 and 2016 from diseased cats (n = 115 and dogs (n = 231. The presence of blaESBL, PMQR genes, and the azithromycin resistance gene mph(A was confirmed by PCR and sequencing of bla genes. Isolates were further characterized by antimicrobial resistance profiling, multilocus sequence typing, phylogenetic grouping, identification of mutations in the QRDR of gyrA and parC, and screening for virulence-associated genes.ResultsAmong the 346 isolates, 72 (20.8% were confirmed ESBL producers [58 Escherichia coli (E. coli, 11 Klebsiella pneumoniae (K. pneumoniae, and 3 Enterobacter cloacae]. The strains were cultured from urine (n = 45, skin and skin wounds (n = 8, abscesses (n = 6, surgical sites (n = 6, bile (n = 4, and other sites (n = 3. ESBL genes included blaCTX-M-1, 14, 15, 27, 55, and blaSHV-12, predominantly blaCTX-M-15 (54.8%, 40/73, and blaCTX-M-1 (24.7%, 18/73. Further genes included qnrB (4.2%, 3/72, qnrS (9.7%, 7/72, aac(6’-Ib-cr (47.2%, 34/72, and mph(A (38.9%, 28/72. Seventeen (23.6% isolates belonged to the major lineages of human pathogenic K. pneumoniae ST11, ST15, and ST147 and E. coli ST131. The most prevalent ST was E. coli ST410 belonging to phylogenetic group C.ConclusionThe high prevalence of ESBL producing clinical Enterobacteriaceae from cats and dogs in Switzerland and the presence of highly virulent human-related K. pneumoniae and E. coli clones raises concern about transmission prevention as well as infection management and prevention in veterinary medicine.

  2. The effectiveness of simple psychological and exercise interventions for high prevalence mental health problems in young people: a factorial randomised controlled trial

    Moller Bridget

    2011-03-01

    Full Text Available Abstract Background The prevalence of mental illness in young people is the highest of any age group, with the onset of depression, anxiety and substance use peaking between 18 and 24 years. Effective treatments that target sub-threshold or mild to moderate levels of disorder in young people are required to reduce the risk of persistence and recurrence. The aims of this study are to evaluate whether treatments that are less intensive than cognitive-behaviour therapy, such as problem solving therapy and exercise treatments, are acceptable and effective in managing depression and anxiety symptoms in young people and to identify possible attributes in those who are likely to respond to these treatments. Methods/design This is a factorial randomised controlled trial conducted at a large, metropolitan youth mental health service. Participants are young help-seekers aged 15-25 years with sub-threshold or mild to moderate levels of depression and anxiety (with or without comorbid substance use. The interventions comprise 4 treatment combinations delivered by psychologists over 6 sessions on a weekly basis: a psychological intervention (problem solving therapy versus supportive counselling and an exercise intervention (behavioural exercise versus psychoeducation. Structured assessments occur at baseline, mid-point, end-point (6 weeks and at a 6- and 12-month follow-up. The primary outcomes are depression and anxiety symptoms as measured by the Beck Depression and Anxiety Inventories. Secondary outcomes include remission (defined as no longer meeting the diagnostic criteria for a disorder if threshold level was reached at baseline, or no longer scoring in the clinical range on scale scores if sub-threshold at baseline, substance use, and functioning. Discussion The effectiveness of less complex psychological and exercise interventions in young help-seekers with sub-threshold or mild to moderate presentations of high prevalence disorders is yet to be

  3. High prevalence of HIV-1 transmitted drug-resistance mutations from proviral DNA massively parallel sequencing data of therapy-naïve chronically infected Brazilian blood donors.

    Rodrigo Pessôa

    Full Text Available An improved understanding of the prevalence of low-abundance transmitted drug-resistance mutations (TDRM in therapy-naïve HIV-1-infected patients may help determine which patients are the best candidates for therapy. In this study, we aimed to obtain a comprehensive picture of the evolving HIV-1 TDRM across the massive parallel sequences (MPS of the viral entire proviral genome in a well-characterized Brazilian blood donor naïve to antiretroviral drugs.The MPS data from 128 samples used in the analysis were sourced from Brazilian blood donors and were previously classified by less-sensitive (LS or "detuned" enzyme immunoassay as non-recent or longstanding HIV-1 infections. The Stanford HIV Resistance Database (HIVDBv 6.2 and IAS-USA mutation lists were used to interpret the pattern of drug resistance. The minority variants with TDRM were identified using a threshold of ≥ 1.0% and ≤ 20% of the reads sequenced. The rate of TDRM in the MPS data of the proviral genome were compared with the corresponding published consensus sequences of their plasma viruses.No TDRM were detected in the integrase or envelope regions. The overall prevalence of TDRM in the protease (PR and reverse transcriptase (RT regions of the HIV-1 pol gene was 44.5% (57/128, including any mutations to the nucleoside analogue reverse transcriptase inhibitors (NRTI and non-nucleoside analogue reverse transcriptase inhibitors (NNRTI. Of the 57 subjects, 43 (75.4% harbored a minority variant containing at least one clinically relevant TDRM. Among the 43 subjects, 33 (76.7% had detectable minority resistant variants to NRTIs, 6 (13.9% to NNRTIs, and 16 (37.2% to PR inhibitors. The comparison of viral sequences in both sources, plasma and cells, would have detected 48 DNA provirus disclosed TDRM by MPS previously missed by plasma bulk analysis.Our findings revealed a high prevalence of TDRM found in this group, as the use of MPS drastically increased the detection of these

    The prevalence of HIV and syphilis among middle and high-fee female sex workers (FSWs) has been widely reported but little is known among low-fee FSWs. This study aims to determine the prevalence and associated factors of HIV and syphilis among low-fee FSWs in China. A cross-sectional study design was used. A convenience sample of low-fee FSWs was recruited from venues by outreach workers in 12 cities. Structured questionnaire interviews and blood sampling for HIV and syphilis were carried out. Univariate and multivariate logistic regression were used for assessing potential associated factors. This study enrolled 781 low-fee FSWs. There were 37 (4.7%) HIV positive participants and 117 (15.0%) participants were infected with syphilis. Final multivariate analysis identified five factors associated with HIV infection: older age (OR:2.6, 95% CI:1.1-6.1), local household registration (OR:3.3, 95% CI:1.5-6.9), employed in Yunnan province (OR:2.7, 95% CI:1.1-6.7), soliciting in self-rented rooms and "market day" buildings (OR:3.9, 95% CI:1.5-10.0), injection drug use in the past 6 months (OR:13.5, 95% CI:4.5-40.1); and four factors associated with syphilis infection: older age (OR:1.8, 95% CI:1.2-2.9), employed in Yunnan province (OR:2.1, 95% CI:1.2-3.6), soliciting in self-rented rooms and "market day" buildings (OR:2.3, 95% CI:1.4-3.7) , and no consistent condom use with clients in the past 30 days (OR:1.6, 95% CI:1.0-2.6). A high prevalence of HIV and syphilis were found among low-fee FSWs. Those soliciting in self-rented rooms and "market day" buildings with the lowest income, and injection drug users (IDUs) in this population should take priority in further intervention strategies.

    Anaemia is frequently associated with both HIV-infection and HIV-related tuberculosis (TB) in antiretroviral therapy (ART)-naïve patients in sub-Saharan Africa and is strongly associated with poor prognosis. However, the effect of ART on the resolution of anaemia in patient cohorts with a high prevalence and incidence of tuberculosis is incompletely defined and the impact of TB episodes on haemoglobin recovery has not previously been reported. We therefore examined these issues using data from a well-characterised cohort of patients initiating ART in South Africa. Prospectively collected clinical and haematological data were retrospectively analysed from patients receiving ART in a South African township ART service. TB diagnoses and time-updated haemoglobin concentrations, CD4 counts and HIV viral loads were recorded. Anaemia severity was classified according to WHO criteria. Multivariable logistic regression analysis was used to determine factors independently associated with anaemia after 12 months of ART. Of 1,140 patients with baseline haemoglobin levels, 814 were alive in care and had repeat values available after 12 months of ART. The majority of patients were female (73%), the median CD4 count was 104 cells/uL and 30.5% had a TB diagnosis in the first year of ART. At baseline, anaemia (any severity) was present in 574 (70.5%) patients and was moderate/severe in 346 (42.5%). After 12 months of ART, 218 (26.8%) patients had anaemia of any severity and just 67 (8.2%) patients had moderate/severe anaemia. Independent predictors of anaemia after 12 months of ART included greater severity of anaemia at baseline, time-updated erythrocyte microcytosis and receipt of an AZT-containing regimen. In contrast, prevalent and/or incident TB, gender and baseline and time-updated CD4 cell count and viral load measurements were not independent predictors. Although anaemia was very common among ART-naive patients, the anaemia resolved during the first year of ART in a

  6. Hepatitis C virus in Vietnam: high prevalence of infection in dialysis and multi-transfused patients involving diverse and novel virus variants.

    Linda Dunford

    Full Text Available Hepatitis C virus (HCV is a genetically diverse pathogen infecting approximately 2-3% of the world's population. Herein, we describe results of a large, multicentre serological and molecular epidemiological study cataloguing the prevalence and genetic diversity of HCV in five regions of Vietnam; Ha Noi, Hai Phong, Da Nang, Khanh Hoa and Can Tho. Individuals (n=8654 with varying risk factors for infection were analysed for the presence of HCV Ab/Ag and, in a subset of positive specimens, for HCV RNA levels (n=475 and genotype (n=282. In lower risk individuals, including voluntary blood donors, military recruits and pregnant women, the prevalence of infection was 0.5% (n=26/5250. Prevalence rates were significantly higher (p<0.001 in intravenous drug users (IDUs; 55.6%, n=556/1000, dialysis patients (26.6%, n=153/575 commercial sex workers (CSWs; 8.7%, n=87/1000, and recipients of multiple blood transfusions (6.0%, n=32/529. The prevalence of HCV in dialysis patients varied but remained high in all regions (11-43% and was associated with the receipt of blood transfusions [OR: 2.08 (1.85-2.34, p=0.001], time from first transfusion [OR: 1.07 (1.01-1.13, p=0.023], duration of dialysis [OR: 1.31 (1.19-1.43, p<0.001] and male gender [OR: 1.60 (1.06-2.41, p=0.026]. Phylogenetic analysis revealed high genetic diversity, particularly amongst dialysis and multi-transfused patients, identifying subtypes 1a (33%, 1b (27%, 2a (0.4%, 3a (0.7%, 3b (1.1%, 6a (18.8%, 6e (6.0%, 6h (4.6%, 6l (6.4% and 2 clusters of novel genotype 6 variants (2.1%. HCV genotype 1 predominated in Vietnam (60%, n=169/282 but the proportion of infections attributable to genotype 1 varied between regions and risk groups and, in the Southern part of Vietnam, genotype 6 viruses dominated in dialysis and multi-transfused patients (73.9%. This study confirms a high prevalence of HCV infection in Vietnamese IDUs and, notably, reveals high levels of HCV infection associated with dialysis and

  7. Anabolic Adaptations Occur in Conscripts During Basic Military Training Despite High Prevalence of Vitamin D Deficiency and Decrease in Iron Status.

    In Estonian Defense Forces that are drawn up on the basis of the conscription model considerable numbers of young men are prematurely discharged from military service for medical reasons, but causes leading to premature dropout of conscripts have not been systematically studied. However, one of the factors involved could be relatively demanding physical training that starts at the beginning of military service in the form of basic military training (BMT). Cumulative training and nontraining stresses experienced by conscripts during BMT may exceed their physiological adaptability and increase the probability of becoming prematurely discharged. Therefore, the primary purpose of this study was to assess physiological responses to 10-week BMT in Estonian conscripts. The protocol of the study confirmed to the standards set by the Declaration of Helsinki and it was approved by the Research Ethics Committee of the University of Tartu. Mean ± SD age and body mass index of 94 conscripts studied was 20.9 ± 1.7 years and 24.2 ± 3.0 kg · m -2 , respectively. Fasting venous blood analysis was performed four times during BMT (October to December) and once 15 weeks after the end of BMT (in March). One-factor (time) repeated measures analysis of variance was used to evaluate the differences within the variables. Statistical significance was set at p anabolic physiological adaptations in conscripts despite vitamin D deficiency and decrease in iron status. However, high prevalence of vitamin D deficiency and decline in iron status may limit physiological adaptations and improvement in physical work capacity to a suboptimal level. Furthermore, as vitamin D influences a variety of functions important for health, deficiency in conscripts should be considered a major concern that needs treatment. An acknowledged limitation of the study is the lack of a control group of conscripts possessing normal vitamin D status and stable serum ferritin levels throughout the study period

    established and acute HIV infections) by 10.4% (95% CI, 8.8%-12.2%) and pooled HIV RNA testing increased the relative HIV diagnostic yield by 12.4% (95% CI, 10.7%-14.3%). In a high-prevalence population, HIV screening using an HIV Ag/Ab combination assay following a negative rapid test detected 82% of acute HIV infections detectable by pooled HIV RNA testing, with a positive predictive value of 59%. Further research is needed to evaluate this strategy in lower-prevalence populations and in persons using preexposure prophylaxis for HIV prevention.

  10. The energy situation in five Central American countries

    Trocki, L.; Booth, S.R.; Umana Q, A.

    1987-06-01

    This study describes the energy resources and the changes that have taken place in energy supply and demand in five Central American countries between 1970 and 1984. Economic changes are also reviewed because they influence and are affected by changes in the energy sector. The work was performed under the auspices of the US Agency for International Development. The Central American countries of Costa Rica, El Salvador, Guatemala, Honduras, and Panama are highly dependent on fuel wood as a source of energy, particularly in the residential sector. They also rely upon imported oil products to supply a growing modern sector. Most countries have significant hydroelectric and geothermal resources, and most countries produce a large portion of their electricity from hydroelectric projects. Demand for electricity has grown rapidly. Relative shares of primary versus secondary energy in the five countries vary significantly and strongly correlate with average per capita income. Consumption of secondary energy has declined during the recent economic recession suffered by the region.

    In many developing countries in the South Asian region, screening for chronic diseases in the community has shown a widely varying prevalence. However, certain geographical regions have shown a high prevalence of chronic kidney disease (CKD) of unknown etiology. This predominantly affects the young and middle-aged population with a lower socioeconomic status. Here, we describe the hotspots of CKD of undiagnosed etiology in South Asian countries including the North, Central and Eastern provinces of Sri Lanka and the coastal region of the state of Andhra Pradesh in India. Screening of these populations has revealed cases of CKD in various stages. Race has also been shown to be a factor, with a much lower prevalence of CKD in whites compared to Asians, which could be related to the known influence of ethnicity on CKD development as well as environmental factors. The difference between developed and developing nations is most stark in the realm of healthcare, which translates into CKD hotspots in many regions of South Asian countries. Additionally, the burden of CKD stage G5 remains unknown due to the lack of registry reports, poor access to healthcare and lack of an organized chronic disease management program. The population receiving various forms of renal replacement therapy has dramatically increased in the last decade due to better access to point of care, despite the disproportionate increase in nephrology manpower. In this article we will discuss the nephrology care provided in various countries in South Asia, including India, Bangladesh, Pakistan, Nepal, Bhutan, Sri Lanka and Afghanistan.

    1991-01-01

    The rapid growth of our industrial societies, together with an increased awareness and sense of responsibility towards the environment in most countries, has made us being to understand the urgency of halting and preventing further pollution and destruction of irreparable environments. The main issue sat present focus on neutralizing the harmful effects of toxic waste by isolating it from the biosphere for long periods of time, perhaps for many hundreds of thousands of years. These issues no longer focus on radioactive substances and their harmful ionizing radiation effects but also on heavy alloys and chemical pollutants generated during transformation processes of different types of waste, or through incineration of waste. Ash and sedimentary deposits from sewage plants for example, also contain heavy alloys. (au)

  19. Joint ownership of spouses and good faith acquisition of immovables by relying in the real estate cadastre

    Cvetić Radenka M.

    2016-01-01

    Full Text Available The paper examines the rules on transferring of immovables in the matrimonial ownership regime against the backdrop of general notion of joint ownership and joint ownership (property of spouses. It explores whether the party who invokes the principle of reliance in the real estate cadastre shall be protected in the absence of an explicit rule guaranteeing the protection of a good faith acquirer in case of an unauthoriesd transfer done by one of the spouses. In other words, should for the sake of protection of confidence in legal transactions, acquisition of ownership and other rights in rem exceptionally be allowed by the good faith acquirer, provided that general presumptions under which confidence in accuracy and completeness of public registry of rights on immovables are fulfilled, in case where ownership was not inscribed as a joint ownership. The answer has been given in the absence of general rules on joint ownership, taking into account existing rules in the neighbouring countries, principle of reliance in the real estate cadastre and with due regard to the stance taken by the highest judicial body in the Republic of Serbia. The conclusion is that a spouse who is not inscribed in the public registry should not benefit from the protection against the good faith acquirer.

  1. Country nuclear power profiles

    NONE

    1998-03-01

    The preparation of Country Nuclear Power Profiles was initiated within the framework of the IAEA`s programme for nuclear power plant performance assessment and feedback. It responded to a need for a database and a technical document containing a description of the energy and economic situation and the primary organizations involved in nuclear power in IAEA Member States. The task was included in the IAEA`s programmes for 1993/1994 and 1995/1996. In March 1993, the IAEA organized a Technical Committee meeting to discuss the establishment of country data ``profiles``, to define the information to be included in the profiles and to review the information already available in the IAEA. Two expert meetings were convened in November 1994 to provide guidance to the IAEA on the establishment of the country nuclear profiles, on the structure and content of the profiles, and on the preparation of the publication and the electronic database. In June 1995, an Advisory Group meeting provided the IAEA with comprehensive guidance on the establishment and dissemination of an information package on industrial and organizational aspects of nuclear power to be included in the profiles. The group of experts recommended that the profiles focus on the overall economic, energy and electricity situation in the country and on its nuclear power industrial structure and organizational framework. In its first release, the compilation would cover all countries with operating power plants by the end of 1995. It was also recommended to further promote information exchange on the lessons learned from the countries engaged in nuclear programmes. For the preparation of this publication, the IAEA received contributions from the 29 countries operating nuclear power plants and Italy. A database has been implemented and the profiles are supporting programmatic needs within the IAEA; it is expected that the database will be publicly accessible in the future. Refs, figs, tabs.

  5. Country report: a methodology

    Colin, A.

    2013-01-01

    This paper describes a methodology which could be applicable to establish a country report. In the framework of nuclear non proliferation appraisal and IAEA safeguards implementation, it is important to be able to assess the potential existence of undeclared nuclear materials and activities as undeclared facilities in the country under review. In our views a country report should aim at providing detailed information on nuclear related activities for each country examined taken 'as a whole' such as nuclear development, scientific and technical capabilities, etc. In order to study a specific country, we need to know if there is already an operating nuclear civil programme or not. In the first case, we have to check carefully if it could divert nuclear material, if there are misused declared facilities or if they operate undeclared facilities and conduct undeclared activities aiming at manufacturing nuclear weapon. In the second case, we should pay attention to the development of a nuclear civil project. A country report is based on a wide span of information (most of the time coming from open sources but sometimes coming also from confidential or private ones). Therefore, it is important to carefully check the nature and the credibility (reliability?) of these sources through cross-check examination. Eventually, it is necessary to merge information from different sources and apply an expertise filter. We have at our disposal a lot of performing tools to help us to assess, understand and evaluate the situation (cartography, imagery, bibliometry, etc.). These tools allow us to offer the best conclusions as far as possible. The paper is followed by the slides of the presentation. (author)

  6. Medium-to-high prevalence of screening-detected parkinsonism in the urban area of Tehran, Iran: data from a community-based door-to-door study.

    Parkinsonism occurs in all ethnic groups worldwide; however, there are wide variations in the prevalence rates reported from different countries, even for neighboring regions. The huge socioeconomic burden of parkinsonism necessitates the need for prevalence studies in each country. So far, there is neither data registry nor prevalence information on parkinsonism in the Iranian population. The aim of our study was to estimate the prevalence rate of probable parkinsonism in a huge urban area in Iran, Tehran using a community-based door-to-door survey. We used a random multistage sampling of the households within the network of health centers consisting of 374 subunits in all 22 districts throughout the entire urban area of Tehran. Overall, 20,621 individuals answered the baseline checklist and screening questionnaire and data from 19,500 persons aged ≥30 years were entered in the final analysis. Health care professionals used a new six-item screening questionnaire for parkinsonism, which has been previously shown to have a high validity and diagnostic value in the same population. A total of 157 cases were screened for parkinsonism using the validated six-item questionnaire. After age and sex adjustment based on the Tehran population, the prevalence of parkinsonism was calculated as 222.9 per 100,000. Using the World Health Organization's World Standard Population, the standardized prevalence rate of parkinsonism was 285 per 100,000 (95% confidence interval 240-329). The male:female ratio of probable parkinsonism was calculated as 1.62, and there was a significant increase in the screening rate by advancing age. The calculated rates for the prevalence of parkinsonism in our study are closer to reports from some European and Middle Eastern countries, higher than reports from Eastern Asian and African populations, and lower than Australia. The prevalence rate of >200 in 100,000 for parkinsonism in Tehran, Iran could be considered a medium-to-high rate.

    Classical homocystinuria is due to cystathionine beta-synthase (CBS) deficiency. More than 130 mutations, which differ in prevalence and severity, have been described at the CBS gene. Mutation p.I278T is very prevalent, has been found in all European countries where it has been looked for with the exception of the Iberian peninsula, and is known to respond to vitamin B6. On the other hand, mutation p.T191M is prevalent in Spain and Portugal and does not respond to B6. We analysed 30 pedigrees from Spain, Portugal, Colombia and Argentina, segregating for homocystinuria. The p.T191M mutation was detected in patients from all four countries and was particularly prevalent in Colombia. The number of p.T191M alleles described in this study, together with those previously published, is 71. The prevalence of p.T191M among CBS mutant alleles in the different countries was: 0.75 in Colombia, 0.52 in Spain, 0.33 in Portugal, 0.25 in Venezuela, 0.20 in Argentina and 0.14 in Brazil. Haplotype analyses suggested a double origin for this mutation. No genotype-phenotype correlation other than the B6-nonresponsiveness could be established for the p.T191M mutation. Additionally, three new mutations, p.M173V, p.I429del and c.69_70+8del10, were found. The p.M173V was associated with a mild, B6-responsive, phenotype.

  13. High prevalence of hepatitis E virus antibodies in Sao Paulo, Southeastern Brazil: analysis of a group of blood donors representative of the general population.

    Passos-Castilho, Ana Maria; Reinaldo, Mônica Renata; Sena, Anne de; Granato, Celso F H

    Brazil is a non-endemic country for hepatitis E virus (HEV) infection with seroprevalence from 1% to 4% in blood donors and the general population. However, data on seroprevalence of HEV in the country are still limited. This study evaluated the prevalence of past or present HEV infection in a group of blood donors representative of the general population of the city of Sao Paulo, Southeastern Brazil. Serum samples from 500 blood donors were tested from July to September 2014 by serological and molecular methods. Anti-HEV IgG antibodies were detected in 49 (9.8%) subjects and categorized age groups revealed an age-dependent increase of HEV seroprevalence. Among the anti-HEV IgG positive subjects, only 1 had anti-HEV IgM while none tested positive for HEV-RNA. The present data demonstrate a higher seroprevalence of anti-HEV IgG than previously reported in the region. Copyright © 2017 Sociedade Brasileira de Infectologia. Published by Elsevier Editora Ltda.

    2017-09-01

    Methicillin-resistant Staphylococcus aureus (MRSA) is a pathogen associated with severe infections in companion animals present in the community, and it is diagnosed in animals admitted to veterinary hospitals. However, reports that describe the circulation of MRSA in animal populations and veterinary settings in Latin America are scarce. Therefore, the objective of this study was to determine the prevalence and investigate the molecular epidemiology of MRSA in the environment of the largest veterinary teaching hospital in Costa Rica. Preselected contact surfaces were sampled twice within a 6-week period. Antimicrobial resistance, SCCmec type, Panton-Valentine leukocidin screening, USA type, and clonality were assessed in all recovered isolates. Overall, MRSA was isolated from 26.5% (27/102) of the surfaces sampled, with doors, desks, and examination tables most frequently contaminated. Molecular analysis demonstrated a variety of surfaces from different sections of the hospital contaminated by three highly related clones/pulsotypes. All, but one of the isolates were characterized as multidrug-resistant SCCmec type IV-USA700, a strain sporadically described in other countries and often classified as community acquired. The detection and frequency of this unique strain in this veterinary setting suggest Costa Rica has a distinctive MRSA ecology when compared with other countries/regions. The high level of environmental contamination highlights the necessity to establish and enforce standard cleaning and disinfection protocols to minimize further spread of this pathogen and reduce the risk of nosocomial and/or occupational transmission of MRSA.

    Soil-transmitted helminthiases (hookworms, Ascaris lumbricoides and Trichuris trichiura) are extremely prevalent in school-aged children living in poor sanitary conditions. Recent epidemiological data suggest that Strongyloides stercoralis is highly unreported. However, accurate data are essential for conducting interventions aimed at introducing control and elimination programmes. We conducted a cross-sectional survey of 396 randomly selected school-aged children in Amhara region in rural area in north-western Ethiopia, to assess the prevalence of S. stercoralis and other intestinal helminths. We examined stools using three techniques: conventional stool concentration; and two S. stercoralis-specific methods, i.e. the Baermann technique and polymerase chain reaction. The diagnostic accuracy of these three methods was then compared. There was an overall prevalence of helminths of 77.5%, with distribution differing according to school setting. Soil-transmitted helminths were recorded in 69.2%. Prevalence of S. stercoralis and hookworm infection was 20.7 and 54.5%, respectively, and co-infection was detected in 16.3% of cases. Schistosoma mansoni had a prevalence of 15.7%. Prevalence of S. stercoralis was shown 3.5% by the conventional method, 12.1% by the Baermann method, and 13.4% by PCR, which thus proved to be the most sensitive. Our results suggest that S. stercoralis could be overlooked and neglected in Ethiopia, if studies of soil-transmitted helminths rely on conventional diagnostic techniques alone. A combination of molecular and stool microscopy techniques yields a significantly higher prevalence. In view of the fact that current control policies for triggering drug administration are based on parasite prevalence levels, a comprehensive diagnostic approach should instead be applied to ensure comprehensive control of helminth infections.

  3. DEVELOPING COUNTRIES. TRANSITION ECONOMIES

    Dumitru FILIPEANU

    2016-05-01

    Full Text Available According to the modern theories of economic development – the take-off, backwardness, convergence and balanced growth hypothesis - the new industrialized states from Asia seem to have noticed the advantages of backwardness from which low income countries benefited, namely the possibility to take advantage of the latest technological discoveries of advanced countries, thus achieving a faster growth than the latter which operated closer to the technological border. The assimilation of appropriate technologies, however, required the efficient mobilization and allocation of resources and the improvement of human and physical capital. While the Western countries were confronted with crises generated by inflationary shocks and movements of speculative capital, the relative isolation of countries whose economy was planned by the world economy sheltered them until 1990, unemployment being practically non-existent. Asia's exceptional economic success is not only due to borrowing Western practices, but also to the fact that Asian societies maintained certain traditional features of their own culture - such as a strong work ethic - and integrated them in the modern business environment.

  11. Macroeconomics in develpoing countries

    Deepak Nayyar

    2007-09-01

    Full Text Available This essay analyzes the differences between the economies of industrialized countriesand developing countries, which have important implications for macroeconomics interms of theory and policy. It considers the differences in macroeconomic objectives andexamines why the reach of macroeconomic policies is different in the two sets ofcountries. It argues that the distinction between short-run macroeconomic models andlong-term growth models is not quite appropriate for developing countries, wheremacroeconomic constraints on growth straddle time horizons and short-term policieshave long-term consequences. The essential hypothesis is that the nature of relationshipsand the direction of causation in macroeconomics, which shape analysis, diagnosis andprescription, depend on the institutional setting and not the analytical structure of models.And even if some laws of economics are universal, the functioning of economies can bemarkedly different. Therefore, economic theory and policy analysis should recognize,rather than ignore, such myriad differences.

  12. Botswana country study

    1999-09-01

    This study was carried out in Botswana, Tanzania and Zambia as part of the project `Climate Change Mitigation in Southern Africa` funded by the Danish International Development Agency (Danida). The project was conducted parallel to the UNEP/GEF project `Economics of Greenhouse Gas Limitations` which involved 8 other developing countries and 2 regional projects in Latin America and the SADC region. The limitation of greenhouse gas (GHG) emissions is a complex issue, intimately connected with economic development at local, national, regional and global levels. Key economic sectors such as energy, agriculture, industry and forestry all produce GHGs, and are likely to be affected directly and indirectly by any mitigation policy. The UNEP Greenhouse Gas Abatement Costing Studies, initiated in 1991, attempted to address these complex issues, developing a methodological framework and testing it through practical application in ten countries.

  20. Cyclotrons in developing countries

    Vera Ruiz, Hernan

    2004-01-01

    Cyclotron accelerators are prolific sources of charged particle for the production of radionuclides and have become an essential tool in the practice of modern nuclear medicine by providing reliable radiotracers for SPECT and PET studies. In a recent survey conducted by the IAEA in 2001, the growth in the number of cyclotron facilities installed in laboratories and hospitals in developed as well as developing countries was recorded. This trend, which started in the late 70's, continues in the present time also and all indications are that it will continue in the next five to ten years. The reasons for this growth are several: technology involved has become more user or 'hospital friendly', third party reimbursement for several clinical studies based on F-18 PET radiopharmaceuticals at least in some of the advanced countries started in 1998 and above all, the clear irrefutable and demonstrable conclusion of the positive cost/benefit outcomes of PET studies in the field of oncology to a lesser degree, thus far, for cardiology and neurology. It is however recognizable that the overall financial cost of the technology, which comprises the premises to house the facility, the cyclotron accelerator, the corresponding radiochemistry and quality control equipment and the PET cameras can be nevertheless an expensive proposition that requires careful advance planning. This fact is even more relevant when the facility is planned for installation in a developing country, which, frequently, in addition to having a lack of sufficient financial resources, do have shortage of qualified human resources to efficiently run the facility. In spite of the above, it is fact that more and more public as well as private organizations in the developing countries are setting up cyclotron/PET programmes or are seriously considering the installation of such a facility

The huge socioeconomic burden of parkinsonism necessitates the need for prevalence studies in each country. So far, there is neither data registry nor prevalence information on parkinsonism in the Iranian population. The aim of our study was to estimate the prevalence rate of probable parkinsonism in a huge urban area in Iran, Tehran using a community-based door-to-door survey.Materials and methods: We used a random multistage sampling of the households within the network of health centers consisting of 374 subunits in all 22 districts throughout the entire urban area of Tehran. Overall, 20,621 individuals answered the baseline checklist and screening questionnaire and data from 19,500 persons aged ≥30 years were entered in the final analysis. Health care professionals used a new six-item screening questionnaire for parkinsonism, which has been previously shown to have a high validity and diagnostic value in the same population.Results: A total of 157 cases were screened for parkinsonism using the validated six-item questionnaire.

    The numerous antigens in the Kell blood group system result from missense nucleotide changes in KEL. Antibodies to antigens in this system can be clinically important. We describe six probands whose plasma contained antibodies to high-prevalence Kell antigens and discuss their relationship. Polymerase chain reaction amplification, direct sequencing, restriction fragment length polymorphism assays, hemagglutination, flow cytometry, and protein modeling were performed by standard methods. Proband 1 (KUCI) and her serologically compatible sister were heterozygous for a nucleotide change in Exon 11 (KEL*1271C/T; Ala424Val). Proband 2 (KANT) was heterozygous for KEL*1283G/T (Arg428Leu) and KEL*1216C/T (Arg406Stop) in Exon 11. Red blood cells (RBCs) from Proband 1 and her sister were not agglutinated by plasma from Proband 2; however, RBCs from Proband 2 were agglutinated by plasma from Proband 1. Probands 3, 4, 5, and 6 had the KEL*1391C>T change associated with the previously reported KETI- phenotype. Proband 5 was also homozygous for KEL*905T>C encoding the K11-K17+ phenotype. Hemagglutination studies revealed an association between KUCI, KANT, KETI, and K11. Protein modeling indicated that whereas Ala424 and Arg428 are clustered, Val302 and Thr464 are not. Ala424 in the Kell glycoprotein is associated with the high-prevalence Kell antigen, KUCI (ISBT 006032), which is detected by the antibody of Proband 1. Arg428 is associated with the high-prevalence Kell antigen, KANT (ISBT 006033). The association between KUCI, KANT, KETI, and K11 and the results of protein modeling are discussed. © 2013 New York Blood Center. Transfusion © 2013 American Association of Blood Banks.

  6. Alcohol consumption and psychological distress in adolescents: a multi-country study.

    Balogun, Olukunmi; Koyanagi, Ai; Stickley, Andrew; Gilmour, Stuart; Shibuya, Kenji

    2014-02-01

    To examine the association between alcohol use and psychological distress among adolescents in a range of developing countries. Secondary data analysis of the Global School-Based Student Health Survey was conducted using nationally representative data from 12 developing countries: Botswana, Grenada, Indonesia, Kenya, Myanmar, the Philippines, Saint Lucia, Saint Vincent and the Grenadines, the Seychelles, Thailand, Trinidad and Tobago, and Uganda. The surveys were conducted between 2003 and 2008 and involved 32,001 adolescents primarily aged 13-15 years. We used multivariate logistic regression analysis to determine the association between alcohol use and psychological distress. The prevalence of past 30-day alcohol use and lifetime drunkenness varied widely across countries, as did the occurrence of psychological distress (anxiety-induced sleeplessness and/or depression). The risk of psychological distress was significantly higher among adolescents when using alcohol in all countries except Myanmar. In nine of the 12 countries, past 30-day alcohol use was associated with psychological distress, while students who had been drunk at least once in their lifetime had an increased risk of experiencing psychological distress in 11 of the study countries. The high prevalence of alcohol use among adolescents and the strength of the association with psychological distress present a major public health challenge in developing countries. The urgent need to reduce adolescent alcohol use necessitates the implementation of context- and culture-specific strategies that reduce the physical availability of alcohol.

    Indonesia faces an HIV epidemic that is in rapid transition. Injecting drug users (IDUs) are among the most heavily affected risk populations, with estimated prevalence of HIV reaching 50% or more in most parts of the country. Although Indonesia started opening methadone clinics in 2003, coverage remains low. We used the Asian Epidemic Model and Resource Needs Model to evaluate the long-term population-level preventive impact of expanding Methadone Maintenance Therapy (MMT) in West Java (43 million people). We compared intervention costs and the number of incident HIV cases in the intervention scenario with current practice to establish the cost per infection averted by expanding MMT. An extensive sensitivity analysis was performed on costs and epidemiological input, as well as on the cost-effectiveness calculation itself. Our analysis shows that expanding MMT from 5% coverage now to 40% coverage in 2019 would avert approximately 2400 HIV infections, at a cost of approximately US$7000 per HIV infection averted. Sensitivity analyses demonstrate that the use of alternative assumptions does not change the study conclusions. Our analyses suggest that expanding MMT is cost-effective, and support government policies to make MMT widely available as an integrated component of HIV/AIDS control in West Java.

To study the adherence to a gluten-free diet of Mexican individuals with celiac disease and nonceliac gluten sensitivity at the time of their first medical and nutritional consultation at a tertiary referral center. A cross-sectional study was performed. A specific questionnaire was used to gather information on demographics, clinical condition, and self-reported adherence to a gluten-free diet, and to determine strict compliance and intentional or inadvertent gluten consumption. All questionnaires were applied by a nutritionist with expertise in gluten-related disorders. Fifty-six patients with celiac disease and 24 with non-celiac gluten sensitivity were included. Overall, 46 (57.5%) subjects perceived themselves as strictly adherent; however, inadvertent gluten intake was frequent in both celiac disease and non-celiac gluten sensitivity patients (39.2 vs. 33.3%; p = 0.2). Intentional consumption was more prevalent in subjects with celiac disease (48.8 vs. 29.1%; p = 0.048) and individuals with non-celiac gluten sensitivity showed better adherence (37.5 vs. 12.5%; p = 0.035). The importance of a gluten-free diet is underestimated by Mexican patients with celiac disease. The role of a team with expertise in gluten-related disorders is essential to identify inadvertent gluten intake.

    Drug-resistant strains of tuberculosis (TB) represent a major threat to global TB control. In low- and middle-income countries, resource constraints make it difficult to identify and monitor cases of resistance using drug susceptibility testing and culture. Molecular assays such as the GeneXpert Mycobacterium tuberculosis/rifampicin may prove to be a cost-effective solution to this problem in these settings. The objective of this study is to evaluate the use of GeneXpert in the diagnosis of pulmonary TB since it was introduced into two tertiary hospitals in Ghana in 2013. A 2-year retrospective audit of clinical cases involving patients who presented with clinically suspected TB or documented TB not improving on standard therapy and had samples sent for GeneXpert testing. GeneXpert identified 169 cases of TB, including 17 cases of rifampicin-resistant TB. Of the seven cases with final culture and drug susceptibility testing results, six demonstrated further drug resistance and five of these were multidrug-resistant TB. These findings call for a scale-up of TB control in Ghana and provide evidence that the expansion of GeneXpert may be an optimal means to improve case finding and guide treatment of drug-resistant TB in this setting.

    Cutaneous leishmaniasis is a neglected tropical disease transmitted by phlebotomine sand flies of the genus Lutzomyia. In South America, cutaneous leishmaniasis is endemic in the majority of countries. There are no previous reports of phlebotomine sand fly host feeding sources in Ecuador. We identified blood meal sources for phlebotomine sand fly species in Valle Hermoso, a hyper endemic area for leishmaniasis in Ecuador. Phlebotomine sand fly collections were carried out during the dry and rainy seasons. PCR and multiplex PCR were performed from DNA extracted from the abdomens of blood-fed females to specifically identify the avian and mammalian blood meal sources. Avian-blood (77%), mammalian-blood (16%) and mixed avian-mammalian blood (7%) were found in the samples. At the species level, blood from chickens (35.5%), humans (2.8%), cows (2.8%) and dogs (1.9%) was specifically detected. Nyssomyia trapidoi was the most common species of Lutzomyia found that fed on birds. The present results may aid the development of effective strategies to control leishmaniasis in Ecuador.

  11. Comparison of Radiation Protection Training in European Countries

    Kozelj, M.

    2001-01-01

    Full text: Practice and implementation of radiation protection in European countries and in majority of other countries all over the world relies on common principles and recommendations established by international organisations. These principles and recommendations were incorporated in national legislation ensuring similar and compatible standards of protection for occupationally exposed workers and members of the public. One of the basic requirements derived from international recommendations is also formal request for training of occupationally exposed workers. The final goals of the training are defined only indirectly through standards of safety and protection. Therefore national regulation regarding radiation protection training in particular country is a result of general approach to education and training, historical circumstances, influence and importance of nuclear technology and other factors influencing health protection and national well-being in general. The result is variety of national regulations ranging from very stringent and detailed to rather general and flexible. Nevertheless, results of implemented training do not differ sufficiently to significantly affect achieved standards of radiation protection. According to available information European countries implement radiation protection training in dissimilar ways. Institutions and organisations involved, as well as form and duration of training varies from country to country. Therefore, it is not possible to determine common rules just by reviewing radiation protection training in different countries. It is the intention of this contribution to analyse and discuss available information regarding radiation protection training and point out the necessity of international co-operation in this field, especially in the sense of the future trends.

  12. Slum residence and child health in developing countries.

    Fink, Günther; Günther, Isabel; Hill, Kenneth

    2014-08-01

    Continued population growth and increasing urbanization have led to the formation of large informal urban settlements in many developing countries in recent decades. The high prevalence of poverty, overcrowding, and poor sanitation observed in these settlements-commonly referred to as "slums"-suggests that slum residence constitutes a major health risk for children. In this article, we use data from 191 Demographic and Health Surveys (DHS) across 73 developing countries to investigate this concern empirically. Our results indicate that children in slums have better health outcomes than children living in rural areas yet fare worse than children in better-off neighborhoods of the same urban settlements. A large fraction of the observed health differences appears to be explained by pronounced differences in maternal education, household wealth, and access to health services across residential areas. After we control for these characteristics, children growing up in the slums and better-off neighborhoods of towns show levels of morbidity and mortality that are not statistically different from those of children living in rural areas. Compared with rural children, children living in cities (irrespective of slum or formal residence) fare better with respect to mortality and stunting but not with respect to recent illness episodes.

    Intestinal parasitic infections (IPIs) pose significant public health challenges in school children in developing countries. The aim of this study is to determine prevalence of intestinal parasites among elementary school children in Mizan-Aman town, southwest Ethiopia. Institution-based cross-sectional study involving 460 elementary school children in Mizan-Aman Town was conducted from May to June 2013. The school children were selected using multistage sampling technique. Data on demography and predisposing factors of IPIs were collected using pretested questionnaire. Moreover, single stool specimen was examined microscopically after wet mount and formol-ether sedimentation concentration procedures. Infection intensity of Schistosoma mansoni and soil-transmitted helminths (STHs) was estimated using Kato-Katz egg counting method. Age of the children ranged from 5 to 17 years. Overall, 76.7% (95%CI: 72.8-80.6) of the children harbored at least one species of intestinal parasite. Eight species of intestinal parasites were detected with S. mansoni (44.8%) and Ascaris lumbricoides (28.7%) being predominant. Helminths and pathogenic intestinal protozoa were detected in 73.9 and 7.8% of the children, respectively. After adjusting for other variables, age between 5 and 9 years (AOR, 2.6, 95%CI, 1.552-4.298), male gender (AOR, 2.1, 95%CI, 1.222-3.526), attending public school (AOR, 0.1, 95%CI, 0.060-0.256), using river/well water (AOR, 2.4, 95%CI, 0.912-6.191), irregular washing of hands before meal (AOR, 0.5, 95%CI, 0.254-0.865), consuming street food (AOR, 2.3, 95%CI, 1.341-3.813) and raw vegetables (AOR, 2.7, 95%CI, 1.594-4.540) were significantly associated with IPIs in the study participants. Prevalence of intestinal parasites among the school children was high. Deworming of the school children and continuous follow up is required.

    Full Text Available Abstract Background Despite the worldwide increasing burden of diabetes, there has been no corresponding scale-up of treatment in developing countries and limited evidence of program effectiveness. In 2002, in collaboration with the Ministry of Health of Cambodia, Médecins Sans Frontières initiated an outpatient program of subsidized diabetic care in two hospital-based chronic disease clinics in rural settings. We aimed to describe the outcomes of newly and previously diagnosed diabetic patients enrolled from 2002 to 2008. Methods We calculated the mean and proportion of patients who met the recommended treatment targets, and the drop from baseline values for random blood glucose (RBG, hemoglobin A1c (HbA1c, blood pressure (BP, and body mass index (BMI at regular intervals. Analysis was restricted to patients not lost to follow-up. We used the t test to compare baseline and subsequent paired values. Results Of 4404 patients enrolled, 2,872 (65% were still in care at the time of the study, 24 (0.5% had died, and 1,508 (34% were lost tofollow-up. Median age was 53 years, 2,905 (66% were female and 4,350 (99% had type 2 diabetes. Median (interquartile range (IQR follow-up was 20 months (5 to 39.5 months. A total of 24% (51/210 of patients had a HbA1c concentration of P P P P 2 after 1 year. Factors associated with loss to follow-up were male sex, age >60 years, living outside the province, normal BMI on admission, high RBG on last visit, and coming late for the last consultation. Conclusion Significant and clinically important improvements in glycemia and BP were observed, but a relatively low proportion of diabetic patients reached treatment targets. These results and the high loss to follow-up rate highlight the challenges of delivering diabetic care in rural, resource-limited settings.

    The diversity of the hepatitis B surface antigen (HBsAg) has a significant impact on the performance of diagnostic screening tests and the clinical outcome of hepatitis B infection. Neutralizing or diagnostic antibodies against the HBsAg are directed towards its highly conserved major hydrophilic region (MHR), in particular towards its "a" determinant subdomain. Here, we explored, on a global scale, the genetic diversity of the HBsAg MHR in a large, multi-ethnic cohort of randomly selected subjects with HBV infection from four continents. A total of 1553 HBsAg positive blood samples of subjects originating from 20 different countries across Africa, America, Asia and central Europe were characterized for amino acid variation in the MHR. Using highly sensitive ultra-deep sequencing, we found 72.8% of the successfully sequenced subjects (n = 1391) demonstrated amino acid sequence variation in the HBsAg MHR. This indicates that the global variation frequency in the HBsAg MHR is threefold higher than previously reported. The majority of the amino acid mutations were found in the HBV genotypes B (28.9%) and C (25.4%). Collectively, we identified 345 distinct amino acid mutations in the MHR. Among these, we report 62 previously unknown mutations, which extends the worldwide pool of currently known HBsAg MHR mutations by 22%. Importantly, topological analysis identified the "a" determinant upstream flanking region as the structurally most diverse subdomain of the HBsAg MHR. The highest prevalence of "a" determinant region mutations was observed in subjects from Asia, followed by the African, American and European cohorts, respectively. Finally, we found that more than half (59.3%) of all HBV subjects investigated carried multiple MHR mutations. Together, this worldwide ultra-deep sequencing based genotyping study reveals that the global prevalence and structural complexity of variation in the hepatitis B surface antigen have, to date, been significantly underappreciated.

    Background Voluntary Medical Male Circumcision (VMMC) is an effective strategy to reduce the risk of HIV infection. Studies conducted in the Dominican Republic (DR) suggest that acceptability of VMMC among men may be as high as 67%. The goal of this clinical trial was to assess the acceptability, uptake and safety for VMMC services in two areas of high HIV prevalence in the country. Methods This was a single-arm, non-randomized, pragmatic clinical trial. Study personnel received background information about the risks and benefits of VMMC and practical training on the surgical technique. A native speaking research assistant administered a questionnaire of demographics, sexual practices and knowledge about VMMC. One week after the surgery, participants returned for wound inspection and to answer questions about their post-surgical experience. Results 539 men consented for the study. Fifty seven were excluded from participation for medical or anatomical reasons and 28 decided not to have the procedure after providing consent. A total of 454 men were circumcised using the Forceps Guided Method Under Local Anesthesia. The rate of adverse events (AE) was 4.4% (20% moderate, 80% mild). There were no serious AEs and all complications resolved promptly with treatment. Eighty eight percent of clients reported being “very satisfied” and 12% were “somewhat satisfied” with the outcome at the one-week postoperative visit. Conclusions Recruitment and uptake were satisfactory. Client satisfaction with VMMC was high and the rate of AEs was low. Roll out of VMMC in targeted areas of the DR is feasible and should be considered. Trial Registration ClinicalTrials.gov NCT02337179 PMID:26367187

    The Middle East respiratory syndrome coronavirus (MERS-CoV) emerged in 2012 on the Arabian Peninsula and has caused severe respiratory disease with more than 800 laboratory-confirmed cases. The return of infected pilgrims to their home countries with a putative spread of MERS-CoV necessitates further surveillance. A cross sectional study of 839 adult African Hajj pilgrims returning to Accra in Ghana, West Africa, was conducted in 2013 to assess the prevalence of respiratory symptoms as well as of MERS-CoV, human rhinovirus (HRV), respiratory syncytial virus (RSV) and influenza A virus (FLU A) infection. Six hundred and fifty-one (77.6%) pilgrims had respiratory symptoms. Tests were positive for at least one of the viruses other than MERS-CoV in 179 (21.3%) of all pilgrims, with 22.4% detection in symptomatic vs. 17.6% detection in asymptomatic pilgrims. No MERS-CoV was detected, although common respiratory viruses were prevalent, with positive findings for HRV in 141 individuals (16.8%), RSV in 43 individuals (5.1%) and FLU A in 11 individuals (1.3%). Results were positive for more than one virus in 16 (1.9%) individuals, including 14 (1.7%) RSV/HRV co-infections and 2 (0.2%) FLU A/HRV co-infections. A total 146 (22.4%) of the symptomatic returnees tested positive for at least one respiratory virus compared with 33 (17.6%) of the asymptomatic pilgrims who had at least one detectable virus in their sample. The prevalence of viral respiratory infections among Hajj pilgrims in both symptomatic and asymptomatic subjects was high. Although it is reassuring that MERS-CoV was not detected in the tested population, there is a need for active surveillance of Hajj pilgrims. © 2015 John Wiley & Sons Ltd.

  18. High prevalence of hepatitis e virus in Swedish moose--a phylogenetic characterization and comparison of the virus from different regions.

    Jay Lin

    Full Text Available Hepatitis E virus (HEV infects a range of species, including humans, pigs, wild boars and deer. Zoonotic transmission may contribute to the high HEV seroprevalence in the human population of many countries. A novel divergent HEV from moose (Alces alces in Sweden was recently identified by partial genome sequencing. Since only one strain was found, its classification within the HEV family, prevalence in moose and zoonotic potential was unclear. We therefore investigated samples from 231 moose in seven Swedish counties for HEV, and sequenced a near complete moose HEV genome. Phylogenetic analysis to classify this virus within the family Hepeviridae and to explore potential host specific determinants was performed.The HEV prevalence of moose was determined by PCR (marker for active infection and serological assays (marker of past infection of sera and 51 fecal samples from 231 Swedish moose. Markers of active and past infection were found in 67 (29% animals, while 34 (15% were positive for HEV RNA, 43 (19% were seropositive for anti-HEV antibodies, and 10 (4% had both markers. The number of young individuals positive for HEV RNA was larger than for older individuals, and the number of anti-HEV antibody positive individuals increased with age. The high throughput sequenced moose HEV genome was 35-60% identical to existing HEVs. Partial ORF1 sequences from 13 moose strains showed high similarity among them, forming a distinct monophyletic clade with a common ancestor to HEV genotype 1-6 group, which includes members known for zoonotic transmission.This study demonstrates a high frequency of HEV in moose in Sweden, with markers of current and past infection demonstrated in 30% of the animals. Moose is thus an important animal reservoir of HEV. The phylogenetic relationship demonstrated that the moose HEV belonged to the genotype 1-6 group, which includes strains that also infect humans, and therefore may signify a potential for zoonotic transmission

  19. High prevalence of Beijing and EAI4-VNM genotypes among M. tuberculosis isolates in northern Vietnam: sampling effect, rural and urban disparities.

    Van Anh Thi Nguyen

    Full Text Available A total of 221 isolates of M. tuberculosis were sampled from hospitals and the general population in the northern plain of Vietnam, one of the most populated region of the country. Genotypic composition and diversity were characterized, and we investigated how they are affected by sampling (hospital vs. general population, correcting for potential confounding effects (location, age and gender of the patients. Spoligotyping and 12 MIRU-VNTR typing were used as first line. Then 15 MIRU-VNTR standard set was used, making 21 MIRU-VNTR typing for the clustered isolates. Result showed that 8 lineages and 13 sub-lineages were circulating in the region. The most predominant lineages were Beijing (38.5% and EAI (38.5%. Others appeared with small proportions H (1.4%, LAM (1.8%, T (8.1%, X (0.9%, MANU (2.3%, and Zero (0.4%. Higher clustering rate was found in the hospital samples (17.9% in urban and 19.2% in rural areas compared to the population ones (0%. The typical Vietnamese EAI4-VNM sub-lineage of EAI lineage accounted for 67% of EAI strains and was associated with older ages. Beijing genotypes were associated with younger, urban population and were characterized by high clustering rates. These characteristics strongly suggest that Beijing strains are invading the population, replacing the local EAI-VNM4, thus predicting a more serious tuberculosis situation in the future in the absence of more effective control strategies.

    Within months, Belgium will have to import practically all of its energy requirements; coal production will stop in 1992. Though nuclear will continue to provide the bulk of the country's power supply, government policy has shifted away from reliance on the atom for electricity generation towards natural gas. With no oil reserves of its own, keeping demand under check has been a priority for governments down the years. The actual level of oil imports runs well above consumption since the refining sector supplies products for the European market. Belgium's own petrol station businesses face considerable rationalisation, with average throughput well below EC levels. (author)

    The airborne geophysical surveys developed in Argentina are described. They have got more than 500.000 km 2 acquiring data for U, Th, K and total background activity. Other types of published data are also mentioned (satellite imagery, seismic hazard, climate, soil distributions, etc.). The availability of maps with the abundances of elements analyzed at the country and also at laboratories from Canada is described, as well as data of analysis of several elements at two study areas proposed at the outset of the project. The availability of process rate data and epidemiological data is also explained. Argentina intended fully to participate in the CRP at the outset of the project. Due, however, to external resource constraints imposed on the participating organization (Comision Nacional de Energia Atomica, CNEA), the level of participation had to be significantly reduced. Nonetheless, in the first period of the CRP, Argentina undertook to collate existing geological and geochemical information within the country, and began to define potential areas for site specific natural systems safety indicator studies.

    Illicit trafficking of radioactive minerals, precious metals and nuclear materials is generally expanded practice in some parts of the Democratic Republic of Congo. The phenomenon took place early in 1990 and amplified from 1998. The main causes of this practice are political instability that led to general poverty among population and the lack of legal framework governing the exploitation of minerals. Nuclear Illicit trafficking in Congo concerns radioactive mineral sand precious metals in eastern and southern parts of the country. The unfavorable political environment that took place in Congo in the 1990s resulted in local manpower and mine workers immigrating to neighboring countries. A great fraction of these new jobless started exploiting abandoned mines residues searching for Cu, Co and Au for survival. First cases of illicit exploitation of uranium minerals were reported very soon after rock sliding that occurred in 2004 on Shinkolobwe site in Katanga region. This uncontrolled mineral exploitation got worse when several mining companies were licensed by GECAMINES company to explore, exploit, purchase minerals from individuals and export raw materials and concentrates.

  9. High Prevalence of Vitamin D Deficiency in Native versus Migrant Mothers and Newborns in the North of Italy: A Call to Act with a Stronger Prevention Program.

    Francesco Cadario

    Full Text Available Vitamin D status during pregnancy is related to neonatal vitamin D status. Vitamin D deficiency has been associated with an increased risk of rickets in children and osteomalacia in adults. Aim of this study was to investigate 25OHD levels in maternal serum and in neonatal blood spots in native and migrant populations living in Novara (North Italy, 45°N latitude.We carried out a cross sectional study from April 1st 2012 to March 30th 2013, in a tertiary Care Center. Maternal blood samples after delivery and newborns' blood spots were analyzed for 25OHD levels in 533 pairs. Maternal country of origin, skin phototype, vitamin D dietary intake and supplementation during pregnancy were recorded. Multivariate regression analysis, showed a link between neonatal and maternal 25OHD levels (R-square:0.664. Severely deficient 25OHD values (<25 nmol/L were found in 38% of Italian and in 76.2% of migrant's newborns (p <0.0001, and in 18% of Italian and 48,4% of migrant mothers (p <0.0001 while 25OHD deficiency (≥25 and <50 nmol/L was shown in 40.1% of Italian and 21.7% of migrant's newborns (p <0.0001, and in 43.6% of Italian and 41.3% of migrant mothers (p <0.0001. Italian newborns and mothers had higher 25OHD levels (34.4±19.2 and 44.9±21.2 nmol/L than migrants (17.7±13.7 and 29.7±16.5 nmol/L; p<0.0001. A linear decrease of 25OHD levels was found with increasing skin pigmentation (phototype I 42.1 ±18.2 vs phototype VI 17.9±10.1 nmol/l; p<0.0001. Vitamin D supplementation resulted in higher 25OHD values both in mothers and in their newborns (p<0.0001.Vitamin D insufficiency in pregnancy and in newborns is frequent especially among migrants. A prevention program in Piedmont should urgently be considered and people identified as being at risk should be closely monitored. Vitamin D supplementation should be taken into account when considering a preventative health care policy.

    Since 1995, KNMI published a series of books(1), presenting an annual reconstruction of weather and climate in the Low Countries, covering the period AD 763-present, or roughly, the last millennium. The reconstructions are based on the interpretation of documentary sources predominantly and comparison with other proxies and instrumental observations. The series also comprises a number of classifications. Amongst them annual classifications for winter and summer temperature and for winter and summer dryness-wetness. The classification of temperature have been reworked into peer reviewed (2) series (AD 1000-present) of seasonal temperatures and temperature indices, the so called LCT (Low Countries Temperature) series, now incorporated in the Millennium databases. Recently we started a study to convert the dryness-wetness classifications into a series of precipitation; the so called LCP (Low Countries Precipitation) series. A brief outline is given here of the applied methodology and preliminary results. The WMO definition for meteorological drought has been followed being that a period is called wet respectively dry when the amount of precipitation is considerable more respectively less than usual (normal). To gain a more quantitative insight for four locations, geographically spread over the Low Countries area (De Bilt, Vlissingen, Maastricht and Uccle), we analysed the statistics of daily precipitation series, covering the period 1900-present. This brought us to the following definition, valid for the Low Countries: A period is considered as (very) dry respectively (very) wet if over a continuous period of at least 60 days (~two months) cq 90 days (~three months) on at least two out of the four locations 50% less resp. 50% more than the normal amount for the location (based on the 1961-1990 normal period) has been measured. This results into the following classification into five drought classes hat could be applied to non instrumental observations: Very wet period

  12. High prevalence of malaria in Zambezia, Mozambique: the protective effect of IRS versus increased risks due to pig-keeping and house construction.

    Emmanuel A Temu

    Full Text Available BACKGROUND: African countries are scaling up malaria interventions, especially insecticide treated nets (ITN and indoor residual spraying (IRS, for which ambitious coverage targets have been set. In spite of these efforts infection prevalence remains high in many parts of the continent. This study investigated risk factors for malaria infection in children using three malaria indicator surveys from Zambezia province, Mozambique. The impact of IRS and ITNs, the effects of keeping farm animals and of the construction material of roofs of houses and other potential risk factors associated with malaria infection in children were assessed. METHODS: Cross-sectional community-based surveys were conducted in October of 2006, 2007 and 2008. A total of 8338 children (ages 1-15 years from 2748 households were included in the study. All children were screened for malaria by rapid diagnostic tests. Caregiver interviews were used to assess household demographic and wealth characteristics and ITN and IRS coverage. Associations between malaria infection, vector control interventions and potential risk factors were assessed. RESULTS: Overall, the prevalence of malaria infection was 47.8% (95%CI: 38.7%-57.1% in children 1-15 years of age, less than a quarter of children (23.1%, 95%CI: 19.1%-27.6% were sleeping under ITN and almost two thirds were living in IRS treated houses (coverage 65.4%, 95%CI: 51.5%-77.0%. Protective factors that were independently associated with malaria infection were: sleeping in an IRS house without sleeping under ITN (Odds Ratio (OR= 0.6; 95%CI: 0.4-0.9; additional protection due to sleeping under ITN in an IRS treated house (OR = 0.5; 95%CI: 0.3-0.7 versus sleeping in an unsprayed house without a ITN; and parental education (primary/secondary: OR = 0.6; 95%CI: 0.5-0.7 versus parents with no education. Increased risk of infection was associated with: current fever (OR = 1.2; 95%CI: 1.0-1.5 versus no fever; pig keeping (OR

  13. Country profile: Hungary

    1991-09-01

    Country Profile: Hungary has been prepared as a background document for use by US Government agencies and US businesses interested in becoming involved with the new democracies of Eastern Europe as they pursue sustainable economic development. The focus of the Profile is on energy and highlights information on Hungary`s energy supply, demand, and utilization. It identifies patterns of energy usage in the important economic sectors, especially industry, and provides a preliminary assessment for opportunities to improve efficiencies in energy production, distribution and use by introducing more efficient technologies. The use of more efficient technologies would have the added benefit of reducing the environmental impact which, although is not the focus of the report, is an issue that effects energy choices. The Profile also presents considerable economic information, primarily in the context of how economic restructuring may affect energy supply, demand, and the introduction of more efficient technologies.

    BATAN started to study EB (electron beam) flue gas treatment in 2001 after a joint memorandum of understanding on application of EB flue gas treatment in Power Plant between BATAN (National Nuclear Energy Agency), BPPT (Technology Implementation and Assessment Agency) and Indonesia Power Company was signed. Among several power plants (coal or oil) in Indonesia only one is installed with flue gas treatment equipment. This is to reduce CO 2 emission from the newest of coal power plant in Indonesia with 1200 MWe. The BATAN starts by seeking and learning data and engineering concept and processes from other countries to install an EB flue gas treatment equipment. The role of demonstration plant installation is very important to the future EB flue gas treatment in Indonesia. (S. Ohno)

    2012-01-01

    Full Text Available Objective: To describe the background and strategy required for the prevention of blindness from glaucoma in developing countries. Materials and Methods: Extrapolation of existing data and experience in eye care delivery and teaching models in an unequally developed country (India are used to make recommendations. Results: Parameters like population attributable risk percentage indicate that glaucoma is a public health problem but lack of simple diagnostic techniques and therapeutic interventions are barriers to any effective plan. Case detection rather than population-based screening is the recommended strategy for detection. Population awareness of the disease is low and most patients attending eye clinics do not receive a routine comprehensive eye examination that is required to detect glaucoma (and other potentially blinding eye diseases. Such a routine is not taught or practiced by the majority of training institutions either. Angle closure can be detected clinically and relatively simple interventions (including well performed cataract surgery can prevent blindness from this condition. The strategy for open angle glaucoma should focus on those with established functional loss. Outcomes of this proposed strategy are not yet available. Conclusions: Glaucoma cannot be managed in isolation. The objective should be to detect and manage all potential causes of blindness and prevention of blindness from glaucoma should be integrated into existing programs. The original pyramidal model of eye care delivery incorporates this principle and provides an initial starting point. The routine of comprehensive eye examination in every clinic and its teaching (and use in residency programs is mandatory for the detection and management of potentially preventable blinding pathology from any cause, including glaucoma. Programs for detection of glaucoma should not be initiated unless adequate facilities for diagnosis and surgical intervention are in place and

    This paper analyzes the factors influencing whether countries become tax havens. Roughly 15 percent of countries are tax havens; as has been widely observed, these countries tend to be small and affluent. This paper documents another robust empirical regularity: better-governed countries are much more likely than others to become tax havens. Using a variety of empirical approaches, and controlling for other relevant factors, governance quality has a statistically significant and quantitativel...

    Henriques, H

    1996-01-01

    Prior to the successful, low-cost, multimedia campaigns of GAPA-Bahia (GAPA-BA), a nongovernmental organization (NGO), campaigns to educate people about HIV, AIDS, and sexually transmitted diseases (STDs) were produced by the Brazilian National AIDS/STD Program. Their first campaign, in 1990, focused on fear; their second, in 1995, known as the Braulio campaign, targeted poor men with little education via a conversation between a man and his penis "which had its own will power, opinions about condoms, and a compulsion to have sex." Both campaigns failed. GAPA-BA, in 1990, joined the chorus protesting the campaigns; the NGO believed the messages failed because 1) frightening people drives them away from information and 2) frequent association of AIDS with death is depressing and carries a subliminal message of guilt to those infected. GAPA-BA became the first NGO to produce low-cost, multimedia campaigns nationwide. They focused on "the social responsibility of fighting the disease while emphasizing the value of life and individual sexual freedom." The first campaign, in 1993 and in 1994, used charismatic singers to send short messages encouraging individual responsibility in condom use. The second campaign, in 1995, used "elements from the local culture by affirming the Afro-Bahain heritage expressed in popular music and dance." The light-hearted prevention message during Carnival was "Don't hide from pleasure, avoid AIDS" as a condom was inflated. The 1996 campaign ("Don't rely on luck; use a condom") required five newspaper ads, radio spots, TV ads, 25,000 posters, billboards, and ads on public buses. Five HIV-infected or HIV-affected persons spoke about their lives. This was the first time people living with HIV/AIDS took on educational roles and shed their dangerous and frightening stereotypes. The campaigns are sponsored by donors or remain low in cost because community-based organizations have sensitized other social actors who respond through the community

    Throughout many countries, professional bodies rely on yearly self-assessment of competence for ongoing registration; therefore, nursing competence is pivotal to safe clinical practice. Our aim was to describe and compare perioperative nurses' perceptions of competence in four countries, while examining the effect of specialist education and years of experience in the operating room. We conducted a secondary analysis of cross-sectional surveys from four countries including; Australia, Canada, Scotland, and Sweden. The 40-item Perceived Perioperative Competence Scale-Revised (PPCS-R), was used with a total sample of 768 respondents. We used a factorial design to examine the influence of country, years of experience in the operating room and specialist education on nurses' reported perceived perioperative competence. Regardless of country origin, nurses with specialist qualifications reported higher perceived perioperative competence when compared to nurses without specialist education. However, cross-country differences were dependent on nurses' number of years of experience in the operating room. Nurses from Sweden with 6-10 years of experience in the operating room reported lower perceived perioperative competence when compared to Australian nurses. In comparing nurses with > 10 years of experience, Swedish nurses reported significantly lower perceived perioperative competence when compared to nurses from Australia, Canada and Scotland. Researchers need to consider educational level and years of experience in the perioperative context when examining constructs such as competence.

  7. High prevalence of moderate and severe depressive and anxiety symptoms in polycystic ovary syndrome: a systematic review and meta-analysis.

    Cooney, Laura G; Lee, Iris; Sammel, Mary D; Dokras, Anuja

    2017-05-01

    Do women with polycystic ovary syndrome (PCOS) have an increased prevalence of moderate and severe depressive and anxiety symptoms compared with control women, and do these symptoms correlate with age, BMI, testosterone, hirsutism or insulin resistance (IR)? Women with PCOS have significantly increased odds of moderate and severe depressive and anxiety symptoms, independent of obesity, and the symptoms are weakly associated with age, BMI, elevated testosterone, hirsutism and IR. Previous studies have reported that women with PCOS have an increased prevalence of mild depressive and anxiety symptoms or an increase in mean depression and anxiety scores, although these scores are usually within the normal range. Thus, it is therefore not clear whether these findings are clinically significant. The prevalence of moderate and severe depressive and anxiety symptoms, which require follow-up and would benefit from treatment, is not known in this population. A comprehensive systematic review (SR) was performed up to January 2016 and included 30 cross-sectional studies, representing 3050 subjects with PCOS and 3858 controls, from 10 different countries. The meta-analysis (MA) on depressive symptoms included 18 studies and the MA on anxiety symptoms included 9 studies. A separate SR identified 15 studies for the meta-regression examining the associations with PCOS-related symptoms or comorbidities. All studies included adult women with PCOS, defined by the National Institutes of Health or Rotterdam criteria, and a control group without PCOS. Ovid, Embase, PsychInfo and Cochrane were searched up to January 2016. Included studies used a validated screening tool to compare the prevalence or mean scores of depressive and/or anxiety symptoms. Random effects MA was used to estimate the pooled odds ratio (OR) of depressive and anxiety symptoms.

    1982-01-01

    The advantages to the developing countries of exploiting their uranium deposits in the next two decades to aid their own economic growth are considered. It is pointed out that in spite of the little known geology of these countries less sophisticated surveying methods have turned up large uranium deposits even in developed countries. Carborne surveys with simple crystal-detectors coupled to scintillators can be effective. Intelligent exploration in developing countries can be cheap due to low labour costs and less stringent environmental restraints and the uranium found could be sold to developed countries for their nuclear power programme.

    Since recent financial crises in Asia and Latin America, developing countries have been strongly advised to rely primarily on foreign direct investment (FDI) in order to promote economic development on a sustainable basis. Even harsh critics of rash capital account liberalization argue in favor of opening up towards FDI. Yet, economists know surprisingly little about the driving forces and the economic effects of FDI. There are few undisputed insights on which policymakers can rely. Globaliza...

  10. Countries and companies

    Jenning, J.S.

    1990-01-01

    The trends and factors currently emerging are likely to have significant influence on the way the upstream oil and gas industry evolves in the coming decade. This paper discusses how these trends might influence events in the 1990s, particularly how they might influence relationships between host countries and companies in the oil industry. State owned companies will dominate the industry in resource terms. These statcos fall into three groups: a small group of technically able, financially sound, well-managed companies; a group of consumer statcos that have limited domestic production but significant domestic demand; a large group that are finding it difficult to maintain their production facilities in good standing to maximize recovery from their resources. This paper describes the future private sector as consisting of the Surviving Sisters and smaller, private companies very active in the upstream. How will these various players behave in the years to come? Conventional activity in the upstream will continue as companies seek to optimize their upstream portfolios

  11. Country risk analysis

    David, A.

    1992-01-01

    This paper reports that the oil industry has been an internationally based industry that has been heavily dependent on outside financing sources. Historically, financing came from investment houses that, in most cases, participated in the projects as equity investors. However, investment companies can no longer satisfy the capital requirements of the current high level of exploration and development activities. The current trend is to involve commercial banks on a purely lending basis. Commercial banks, by their nature, are risk averse. In the case of oil and gas exploration and production they are asked to take not only technical risk and price risk but geopolitical risk as well. Methods have been developed by commercial banks to reduce technical and price risks to point which enables them to be comfortable with a loan. However, geopolitical risks are more difficult to assess. The risk associated with many countries are the nationalization of the investment, new tax restrictions, restriction of currency movements, and/or revisions to the production sharing agreements

  12. Tanzania country study

    1999-09-01

    Objectives of this study are to analyse the role of the land use sectors of Tanzania (especially forestry) on mitigation of greenhouse gases. Specific emphasis is placed on the relationship between forestry and energy supply from biomass, as well as other forestry products. This is a follow up study on an earlier effort which worked on mitigation options in the country without and in-depth analysis of the forestry and land use sectors. Analysis of the mitigation scenario has been based on Comprehensive Mitigation Analysis (COMAP). This study has analysed the forestry and land use sector behaviour on the basis of the current policies on land and environment. Furthermore three scenarios have been developed on the basis of what is expected to happen in the sectors, the worse scenario being a catastrophic one where if things takes the business as usual trend then the forest resources will easily be depleted. The TFAP scenario takes into account the implementation of the current plans as scheduled while the mitigation scenario takes into account the GHG mitigation in the implementation of the plans. A Comprehensive Mitigation Analysis Process (COMAP) has been used to analyse the GHG and cost implications of the various programmes under the mitigation scenario. (au) 30 refs.

    Turra, M D

    1994-01-01

    Persons who are infected with human immunodeficiency virus (HIV) or who suffer from acquired immunodeficiency syndrome (AIDS) often have their civil rights violated in Brazil. To remedy this, the Candido Mendes College in Rio de Janeiro introduced a voluntary course, "AIDS - Legal Approaches", into its law curriculum. Incentive was provided by the college's Model Law Office (MLO), where students learn to defend the rights of people in need. Class size is about 25; law professors use recent magazine and newspaper articles, and documentation on lawsuits concerning persons with HIV to teach the class. Course topics include relevant civil law (suits against blood banks), contract law (suits against private health insurance companies which refuse to cover treatment expenses related to HIV or AIDS), family law, inheritance law, labor law (unjust dismissal of persons with HIV), criminal law (intentional transmission of AIDS), violations of basic human rights, and comparative jurisprudence and constitutional law (a comparison of Brazilian law in this area to the laws of other countries). Students, during their field practice periods at the MLO, provide legal assistance to persons with HIV. Approximately 150 cases have been handled, often with positive outcomes, to date. Clients hear about the program via television, radio, and newspapers. Materials and information about lawsuits handled by the MLO are available to other colleges and universities with the hope of stimulating the formation of similar programs elsewhere.

  14. Swaziland: country profile.

    Carrington, L

    1988-06-01

    Although Swaziland had been independent from colonialism for 20 years, a powerful monarch, King Mswati II, continues to control the country's political, religious, and social system. Swaziland has a population of 676,000, half of whom are under 15 years of age. The infant mortality rate is 105/1000 live births and 25% of children die before they reach their 5th birthday. Life expectancy is 54 years. Tribal chiefs, representing the king, hold and distribute about half of the national land. Most of the fertile land remains in the hands of white settler farmers. The concentration of income in foreign companies and urban centers has exacerbated poverty in rural areas. Depreciation of rand-linked local currency has boosted export earnings, but it has also raised the price of food and medical imports. Swaziland's main exports are sugar, wood pulp, chemicals, and fruit, most of which go to the UK and South Africa. The major food crops are maize, beans, groundnuts, and sorghum. About half of the working population is engaged in small-scale subsistence farming, but food yields are declining. The major producers are foreign companies attracted by Swaziland's low taxes and cheap labor supply.

    Fernando Callera

    Full Text Available CONTEXT AND OBJECTIVE: Geographical variations have been described in acute myelogenous leukemia (AML. In Brazil, few studies have been published on this. The aim of this study was to demonstrate the high prevalence of French-American-British (FAB M1 subtype in adults with de novo AML in São José dos Campos, State of São Paulo, Brazil. DESIGN AND SETTING: Retrospective analysis, at Hospital Pio XII in São José dos Campos, a public non-teaching institution. METHODS: Records from 39 consecutive adult patients with de novo AML referred to Hospital Pio XII between January 2002 and September 2004 were reviewed. Peripheral blood and blood marrow smears were reviewed blindly by five hematologists and classified according to FAB criteria. The rates of remission, relapse, mortality according treatment phase, survival and leukemia-free survival were calculated. RESULTS: The prevalence of each category as determined via a consensus among five observers was M0: 0%; M1: 43.6%; M2: 30.7%; M3: 12.8%; M4: 5.1%; M5: 2.6%: M6: 2.6%; and M7: 2.6%. The remission and the relapse rates were 82% and 41% respectively. The mortality rate was 69% (induction of remission: 7/39, 17.9%; post induction: 10/32, 31.2%; and relapse: 10/16, 62.5%. The survival rate was 30% and leukemia-free survival was 33%. CONCLUSIONS: The study demonstrated a high prevalence of FAB M1 subtype in adults with de novo AML in São José dos Campos. Our data suggest the occurrence of different regional prevalences of FAB AML categories in Brazil.

    Linking more than 3000 health and development organizations, the Voluntary Health Association of India (VHAI) is one of the largest networks in the country. In 1990 VHAI began incorporating HIV/STD-related activities into its broader programs. An existing infrastructure for intersectoral collaboration in the areas of community health promotion, public policy, information and documentation, and communications facilitated inclusion of the new activities. Several VHAI departments collaborate in offering training courses, workshops, and seminars at the state and community levels to involve nongovernmental organizations and professional groups in HIV/STD prevention and counseling. More than 950 persons have been trained so far, including trainers of primary health care workers, family physicians, medical practitioners, social scientists, teachers, community volunteer workers, and youth leaders. Local experts act as training resource persons; materials produced locally, abroad, and by VHAI itself are used. Training facilities are offered free of charge to member organizations; VHAI also awards fellowships for field training and financial support for approved projects. VHAI suggests intervention measures to governmental and nongovernmental organizations related to drug users, youth, truck drivers, blood donors, and people living with HIV/AIDS. The information, documentation, and communications departments provide members with a wide variety of information, education, and communication (IEC) materials that can be translated into local languages: posters, folders, flip charts, stickers, and folk songs. VHAI advocacy issues that have been highlighted through the press include: confidentiality, protection against discrimination, the right of all persons to health care, and the need to make properly-equipped STD clinics available. VHAI has established sub-networks in Tamil Nadu (155 organizations) and Manipur (55 organizations) states. VHAI has found that incorporating HIV

  18. COUNTRY IMAGE VS. COUNTRY BRAND: DIFFERENCES AND SIMILARITIES

    2015-08-01

    Full Text Available This article was written in order to provide an overview regarding the differences and similarities regarding two congruent, yet different concepts: country brand and country image. The geopolitical context and, implicitly, the current global context require a redefinition – or a more complex circumscription – of the “country image” and “country branding” concepts. In this paper, the author aimed to highlight the characteristics and particularities of the approached concepts in order to shape a framework of the context within these two operate; a brief analysis of the literature is presented, trying to emphasize the slight difference between the approached concepts

  19. The relationship between iron status and adiposity in women from developing countries: a review.

    Aderibigbe, Olaide Ruth; Pisa, Pedro T; Vorster, Hester H; Kruger, Salome H

    2014-01-01

    Scientific reports have shown that iron deficiency is positively associated with adiposity. With the high prevalence of iron deficiency and obesity in developing countries and women being particularly affected, this review was carried out with the aim of elucidating the link between iron status and adiposity in women from developing countries and to examine factors influencing this relationship. An extensive literature search was conducted using several search engines. A systematic approach with prespecified inclusion criteria was used in selecting relevant literature. Eight studies that met the inclusion criteria were selected for review. The relationship between iron status indices and adiposity in women in developing countries varied widely. While some studies observed negative relationships, some reported positive relationships, and others no significant relationships. Furthermore, other factors such as infection, alcohol consumption, type of diet, and genes were shown to affect the relationship between iron status and adiposity in women in developing countries. In conclusion, the possibility of iron status playing a role in adiposity in women from developing countries is likely, and it may be influenced by several other factors as described in the results. Thus, it is recommended that a special research effort should be directed toward this area.

  20. Cross-country differences in basal and stress-induced cortisol secretion in older adults.

    Juliana N Souza-Talarico

    Full Text Available Several studies have emphasized the association between socioeconomic status (SES and inadequate response of the biological stress system. However, other factors related to SES are rarely considered, such as cultural values, social norms, organization, language and communication skills, which raises the need to investigate cross-country differences in stress response. Although some studies have shown differences in cortisol levels between immigrants and natives, there is no cross-country evidence regarding cortisol levels in country-native elders.

    Several studies have emphasized the association between socioeconomic status (SES) and inadequate response of the biological stress system. However, other factors related to SES are rarely considered, such as cultural values, social norms, organization, language and communication skills, which raises the need to investigate cross-country differences in stress response. Although some studies have shown differences in cortisol levels between immigrants and natives, there is no cross-country evidence regarding cortisol levels in country-native elders. This is particularly important given the high prevalence of stress-related disorders across nations during aging. The current study examined basal diurnal and reactive cortisol levels in healthy older adults living in two different countries. Salivary cortisol of 260 older adults from Canada and Brazil were analyzed. Diurnal cortisol was measured in saliva samples collected at home throughout two working days at awakening, 30 min after waking, 1400 h, 1600 h and before bedtime. Cortisol reactivity was assessed in response to the Trier Social Stress Test (TSST) in both populations. Our results showed that even under similar health status, psychological and cognitive characteristics, Brazilian elders exhibited higher basal and stress-induced cortisol secretion compared to the Canadian participants. These findings suggest that country context may modulate cortisol secretion and could impact the population health.

  2. Strategies for Better Hypertension Control in India and Other Lower Middle Income Countries.

    Gupta, Rajeev; Khedar, Raghuvir Singh; Panwar, Raja Babu

    2016-09-01

    Hypertension is the most important cause of global burden of disease. It is highly prevalent in India and other low and lower-middle income countries. Prevalence of uncontrolled hypertension varies from 70-90% and is significantly greater in rural vs urban locations. Guidelines based treatment strategy has improved blood pressure (BP) control in high income countries but no context-specific guidelines exist in low and lower-middle income countries such as India. There are numerous barriers to proper BP control in these countries and include political apathy, bureaucratic inertia, weak health systems, overburdened healthcare providers and unempowered patients. Hypertension control can be improved in these countries by better political focus on social determinants of health such as education, development of health systems, proper healthcare financing, free or low-cost BP medicines, healthcare provider education for hypertension management, free primary care, task sharing with trained community health workers, patient empowerment and use of technological innovations. © Journal of the Association of Physicians of India 2011.

    Full Text Available Abstract Developing countries can generate effective solutions for today’s global health challenges. This paper reviews relevant literature to construct the case for international cooperation, and in particular, developed-developing country partnerships. Standard database and web-based searches were conducted for publications in English between 1990 and 2010. Studies containing full or partial data relating to international cooperation between developed and developing countries were retained for further analysis. Of 227 articles retained through initial screening, 65 were included in the final analysis. The results were two-fold: some articles pointed to intangible benefits accrued by developed country partners, but the majority of information pointed to developing country innovations that can potentially inform health systems in developed countries. This information spanned all six WHO health system components. Ten key health areas where developed countries have the most to learn from the developing world were identified and include, rural health service delivery; skills substitution; decentralisation of management; creative problem-solving; education in communicable disease control; innovation in mobile phone use; low technology simulation training; local product manufacture; health financing; and social entrepreneurship. While there are no guarantees that innovations from developing country experiences can effectively transfer to developed countries, combined developed-developing country learning processes can potentially generate effective solutions for global health systems. However, the global pool of knowledge in this area is virgin and further work needs to be undertaken to advance understanding of health innovation diffusion.

  6. Dealing with the problem countries

    Jones, R.W.

    1985-01-01

    The test of America's policies to prevent nuclear proliferation is the so-called problem countries, those states that pose the greatest risk of ''going nuclear.'' Most visible - and the source of greatest concern - are those countries which have developed or appear to be in the process of developing nuclear weapons capabilities. In addition to Pakistan, near-nuclear countries of note include India, Israel, South Africa, Argentina, South Korea, and Taiwan. Several other countries, including Iraq, Iran, Libya, and Brazil, seem to pose proliferation risks in the longer term. More problematic are countries, such as Mexico, that, although they seem to represent little or no proliferation risk themselves, pose difficult problems by challenging restrictions in nuclear export policy. The author examines US policy toward some of the problem countries, paying particular attention to Pakistan. The constants in US policy and the few changes wrought by the Reagan administration are noted throughout

  7. Hungary country study

    Uerge-Vorsatz, D.; Fuele, M. [eds.

    1999-09-01

    Hungary recognises the importance of limiting greenhouse gas emissions in order to prevent or mitigate their impact on the global climate. On an international level, Hungary is not a significant carbon dioxide emitter, neither to the absolute degree nor on a per capita basis. This means that the principal reason for Hungarian participation in emission`s reduction is not perceivable international consequences but solidarity and participation in the common action of the countries of the world. Hungary is a signatory to both the Framework Convention on Climate Change and the Kyoto protocol. However, the (Hungarian) National Environmental Program also emphasises that the fulfilment of international conventions must happen at a level and pace reasonable for Hungary. The goal of this study is to investigate the potentials, costs and implementation strategies of greenhouse gas abatement in Hungary. First presented is a background of Hungary`s economy and a summary of the economic transitions in Hungary. A brief description of the Hungarian energy sector is included, with a short summary of carbon dioxide emissions, and of the Hungarian forestry sector. The following chapter is devoted to the development of baseline scenarios, from bottom-up and top-down perspectives. In the chapter on mitigation, the spectrum of energy efficiency measures in the residential and public sectors is discussed. Fifteen specific measures, whose impact is considered important, are selected and discussed in detail. The cost curves are developed for the discussed mitigation options. Then, we discuss the issues related to the implementation of energy efficiency measures in the Hungarian residential and commercial sectors. After a general background and a framework on the implementation of the energy efficiency measures in the sectors chosen, we elaborate on the practicality of these concepts. As a case study, the concept and the feasibility of carbon/energy taxes are examined. To complete the

    2012-09-15

    IRENA Renewable Energy Country Profiles take stock of the latest developments in the field of renewables at country level around the world. Each profile combines analysis by IRENA's specialists with the latest available country data and additional information from a wide array of sources. The resulting reports provide a brief yet comprehensive picture of the situation with regard to renewable energy, including energy supply, electrical generation and grid capacity, and access. Energy policies, targets and projects are also considered, along with each country's investment climate and endowment with renewable energy resources. The energy statistics presented here span the period from 2009 until 2012, reflecting varying timelines in the source material. Since data availability differs from country to country, wider regional comparisons are possible only for the latest year with figures available for every country included. Despite the time lag in some cases, the evident differences and disparities between countries and regions around the world remain striking. The current package of country profiles is just a starting point. The geographic scope will continue to expand, and existing profiles will be enhanced with new indicators, with the whole series maintained as a live product on the IRENA website (www.irena.org)

  13. Domestic biogas development in developing countries

    Rakotojaona, Loic

    2013-07-01

    Communities that rely mostly on agriculture and livestock farming in developing countries can face strong pressure related to: - Energy access: for instance, in Africa, it is estimated that 68% of the population live without clean cooking facilities [1]. Energy access plays a key role in poverty alleviation. - Resources depletion: if a household uses firewood for cooking purposes, forests depletion in some areas makes firewood collection tougher. - Climate change mitigation: agriculture (i.e. the production of crop and livestock products) accounts for 13.5%2 of the global GHG emissions, and extensive systems are sometimes blamed for being less efficient than intensive ones when it comes to climate change mitigation (given that the later involve lower direct emissions per kg of product). In this context, access to clean and sustainable energy through domestic biogas production can help rural communities alleviate current pressures on the environment. In an urban context, domestic biogas in developing countries is also considered as a means for improving hygiene conditions (especially when it comes to public washrooms issues). This report only focuses on domestic biogas development within the frame of small scale agriculture and livestock production (i.e. in rural areas). The main objective of this document is to provide domestic biogas project developers with relevant information on the key issues to have in mind regarding national integration of such projects. This document gives a general presentation of domestic biogas and its main environmental, social and economic benefits. It also browses the main aspects one should have in mind (checklist) in order to assess local risks and opportunities for domestic biogas development

  14. Cytotoxicity Comparison of Harvard Zinc Phosphate Cement Versus Panavia F2 and Rely X Plus Resin Cements on Rat L929-fibroblasts.

    Resin cements, regardless of their biocompatibility, have been widely used in restorative dentistry during the recent years. These cements contain hydroxy ethyl methacrylate (HEMA) molecules which are claimed to penetrate into dentinal tubules and may affect dental pulp. Since tooth preparation for metal ceramic restorations involves a large surface of the tooth, cytotoxicity of these cements would be more important in fixed prosthodontic treatments. The purpose of this study was to compare the cytotoxicity of two resin cements (Panavia F2 and Rely X Plus) versus zinc phosphate cement (Harvard) using rat L929-fibroblasts in vitro. In this experimental study, ninety hollow glass cylinders (internal diameter 5-mm, height 2-mm) were made and divided into three groups. Each group was filled with one of three experimental cements; Harvard Zinc Phosphate cement, Panavia F2 resin cement and Rely X Plus resin cement. L929- Fibroblast were passaged and subsequently cultured in 6-well plates of 5×10(5) cells each. The culture medium was RPMI_ 1640. All samples were incubated in CO2. Using enzyme-linked immune-sorbent assay (ELISA) and (3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) (MTT) assay, the cytotoxicity of the cements was investigated at 1 hour, 24 hours and one week post exposure. Statistical analyses were performed via two-way ANOVA and honestly significant difference (HSD) Tukey tests. This study revealed significant differences between the three cements at the different time intervals. Harvard cement displayed the greatest cytotoxicity at all three intervals. After 1 hour Panavia F2 showed the next greatest cytotoxicity, but after 24-hours and oneweek intervals Rely X Plus showed the next greatest cytotoxicity. The results further showed that cytotoxicity decreased significantly in the Panavia F2 group with time (pHarvard cement group failed to showed no noticeable change in cytotoxicity with time. Although this study has limitations, it provides

  15. Compulsory Schooling Laws and Migration Across European Countries.

    Aparicio Fenoll, Ainhoa; Kuehn, Zoë

    2017-12-01

    Educational attainment is a key factor for understanding why some individuals migrate and others do not. Compulsory schooling laws, which determine an individual's minimum level of education, can potentially affect migration. We test whether and how increasing the length of compulsory schooling influences migration of affected cohorts across European countries, a context where labor mobility is essentially free. We construct a novel database that includes information for 31 European countries on compulsory education reforms passed between 1950 and 1990. Combining this data with information on recent migration flows by cohorts, we find that an additional year of compulsory education reduces the number of individuals from affected cohorts who migrate in a given year by 9 %. Our results rely on the exogeneity of compulsory schooling laws. A variety of empirical tests indicate that European legislators did not pass compulsory education reforms as a reaction to changes in emigration rates or educational attainment.

    Several nuclear research are currently operation in Serpong, Jakarta, Bandung and Yogyakarta; these facilities has been in operation step wisely and having strong link with various universities and laboratories within the country (30 MW in Serpong, 2 MW in Bandung, Cyclotron CS-30 Serpong, Accelerator Yogyakarta, Irradiator Co-60). Public Acceptance: Further more the routine activities of the public information by WiN regarding the peaceful uses of nuclear energy, especially to the immediate environment of the NPP candidate site are indeed of important steps. Future of nuclear power: Since 1990's, Indonesia planned to build NPP station in Jepara to anticipate future energy crisis. Indonesia National Energy Policy has four main objectives: - Securing the continuity of energy supply for domestic use at price affordable to the public, - Enhancing the life quality of the people, - Stimulating economic growth, and, - Reserving an adequate supply of oil and gas for expert to provide source of foreign exchange to fund the national development program. Nuclear Waste Management Policy: Law no 10/1997 on nuclear power became the basic policy in management of radioactive waste The only national agency dealing with radioactive substances, BATAN possesses all data and information concerning the use of nuclear power. Radioactive waste management is particularly earmarked for maximum protection of living creatures, the environment and its ecosystems. In order to guarantee maximum safety and protection, all parties involved in the acquisition of radioactive materials should abide by the ALARA (As Low As Reasonably Achievable) principle. In order to achieve radioactive waste management that complies with the principle of sustainable development, technological applications should be technically and economically viable for maximum protection of the environment and safety from any potential nuclear hazards, now and in future. The application must also be accepted by the community

  20. Transplantation in low resource countries

    2011-12-01

    Full Text Available Thalassemia major (TM is the most common deadly genetic disorder, a major cause of chronic non-infectious morbidity and financial burden in many low and middle-income regions. In these settings few children reach adulthood because proper long-term supportive care is seldom available. Bone marrow transplantation (BMT is the only available curative modality and it can be very successful and cost-effective for young children with low-risk features and a compatible related donor. However, in countries where TM is most prevalent, there is a dire shortage of BMT centers. The Cure2Children Foundation has supported a feasibility study evaluating safety, efficacy and costs of developing a new BMT center in an underserved lower-middle-income country with relatively untrained professionals within a structured collaboration and knowledge-transfer program. A total of 24 consecutive patients who underwent BMT in Pakistan between September 2008 and August 2010 are included in this prospective analysis, 17 from an established bone marrow transplant center, the National Institute for Blood Diseases in Karachi, Pakistan and the initial 7 BMTs from a start up unit in a government civil hospital, the Pakistan Institute of Medical Sciences Children’s Hospital in Islamabad. Patients were matched for age, nutritional status, growth, disease, disease status and post-BMT follow-up time. All patients had a matched-related sibling donor, were younger than 10 years of age at the time of transplantation, received the same conditioning regimen. All needy families could rely on a support program throughout the 8-month post-transplant period. The Cure2Children Foundation provided professional and financial support as well as a structured web-based data management and cooperation platform. At a median follow up of 19.6 months (range 8.7 to 31.5 actuarial thalassemia-free survival is 85.6% and 85.7% and overall survival 94.1% and 85.7% in the established and start-up center

  1. Optimal gasoline tax in developing, oil-producing countries: The case of Mexico

    Antón-Sarabia, Arturo; Hernández-Trillo, Fausto

    2014-01-01

    This paper uses the methodology of Parry and Small (2005) to estimate the optimal gasoline tax for a less-developed oil-producing country. The relevance of the estimation relies on the differences between less-developed countries (LDCs) and industrial countries. We argue that lawless roads, general subsidies on gasoline, poor mass transportation systems, older vehicle fleets and unregulated city growth make the tax rates in LDCs differ substantially from the rates in the developed world. We find that the optimal gasoline tax is $1.90 per gallon at 2011 prices and show that the estimate differences are in line with the factors hypothesized. In contrast to the existing literature on industrial countries, we show that the relative gasoline tax incidence may be progressive in Mexico and, more generally, in LDCs. - Highlights: • We estimate the optimal gasoline tax for a typical less-developed, oil-producing country like Mexico. • The relevance of the estimation relies on the differences between less-developed and industrial countries. • The optimal gasoline tax is $1.90 per gallon at 2011 prices. • Distance-related pollution damages, accident costs and gas subsidies account for the major differences. • Gasoline tax incidence may be progressive in less developed countries

  3. The description-experience gap and its relation to instructional control: Do people rely more on their experience than in objective descriptions?

    Álvaro Viúdez

    2017-11-01

    Full Text Available The present work aims to reveal contradictory results obtained on two different fields; particularly from two studies conducted on the description-experience gap field showing that descriptions are neglected when personal experience is available (1,2, and several others conducted on the instructional control field getting to the opposite conclusion (3–8. To account for this contradiction, we hypothesized that participants from the studies of Jessup, Bishara and Busemeyer (1 and Lejarraga and Gonzalez (2 relied on their experience rather than on the descriptions because of the difficult, demanding nature of the probabilistic descriptions they faced. Enriched descriptions were created in our experiment to assess the contribution of this factor to the differential influence of the descriptions in choice behavior. Nonetheless, our hypothesis did not find support in the results and further research is needed to account for the aforementioned contradiction.

  4. Imputation of missing genotypes within LD-blocks relying on the basic coalescent and beyond: consideration of population growth and structure.

    Kabisch, Maria; Hamann, Ute; Lorenzo Bermejo, Justo

    2017-10-17

    Genotypes not directly measured in genetic studies are often imputed to improve statistical power and to increase mapping resolution. The accuracy of standard imputation techniques strongly depends on the similarity of linkage disequilibrium (LD) patterns in the study and reference populations. Here we develop a novel approach for genotype imputation in low-recombination regions that relies on the coalescent and permits to explicitly account for population demographic factors. To test the new method, study and reference haplotypes were simulated and gene trees were inferred under the basic coalescent and also considering population growth and structure. The reference haplotypes that first coalesced with study haplotypes were used as templates for genotype imputation. Computer simulations were complemented with the analysis of real data. Genotype concordance rates were used to compare the accuracies of coalescent-based and standard (IMPUTE2) imputation. Simulations revealed that, in LD-blocks, imputation accuracy relying on the basic coalescent was higher and less variable than with IMPUTE2. Explicit consideration of population growth and structure, even if present, did not practically improve accuracy. The advantage of coalescent-based over standard imputation increased with the minor allele frequency and it decreased with population stratification. Results based on real data indicated that, even in low-recombination regions, further research is needed to incorporate recombination in coalescence inference, in particular for studies with genetically diverse and admixed individuals. To exploit the full potential of coalescent-based methods for the imputation of missing genotypes in genetic studies, further methodological research is needed to reduce computer time, to take into account recombination, and to implement these methods in user-friendly computer programs. Here we provide reproducible code which takes advantage of publicly available software to facilitate

    In order to rid the people's living of poverty in developing countries, first, the production of food has been planned to increase. And then, resource development and industrialization have been tried to improve with efforts. Because of such development and an increase in population, energy consumption has been increasing. Advanced countries have supported these countries in many ways, however, there is much difference in their assistance depend on various situations such as racial, religious, and political ones. Moreover, a gap between cities and farm villages has widen since infrastructure has not been fully equipped in developing countries. The electrification ratio is used as an index to show the degree of development in developing countries. It is low in the countries where development is lagging, particularly in farm villages. This gap is an urgent problem that faces developing countries. In order to cope with the actual conditions, advanced countries including Japan should be plan to reinforce their technological and economic assistance more suitable for farm villages. Furthermore, they should also improve the assistance system which includes a measure for environmental pollution control, considering the spot directly. 3 figs., 14 tabs.

  12. Photovoltaic marketing in developing countries

    Muntasser, M.A.; Bara, M.F.; Quadri, H.A.; El-Tarabelsi, R.; La-azebi, I.F.

    2000-01-01

    Photovoltaic (PV) insolation-harnessing is acknowledged as the most practical economic solution to meet the requirements of one hundred million people without electricity in the developing countries. Industrialised countries in particular, have been active in utilising such technologies because they can afford the current peak watt prices of US $3-15 for such systems. The market in those countries will soon be close to saturation and attention by suppliers will have to be shifted to the already established larger market in less developed countries (LDCs). PV marketing in these developing countries, i.e. ability to penetrate the potential market, is facing tremendous hurdles. This paper reviews the present status and future directions of the PV market in developing countries as well as discusses the current technical, social, financial or geopolitical barriers and constraints, which are in line with the trends in the world. The paper concludes by making a global policy package proposal, in terms of an appeal on the global community concerned with PV to propagate proposal, in terms of an appeal on the global community concerned with PV to propagate this proposal more convincingly, perhaps to emanate from an internationally recognised 'forum', like a PV conference and exhibition, with cooperation and participation of PV manufacturers, suppliers, industrialised countries, NGOs, financial institutions and developing countries.

    1. Nuclear 2007 highlights: - A magnitude 6.8 earthquake occurred in Niigata on July 16 2007. Owing to this earthquake, 3 units operating and 1 unit during start-up were shutdown automatically at TEPCO's Kashiwazaki-Kariwa NPS. Now, all 7 units of the NPS are in an outage for investigation. This influenced the capacity factor of Japanese NPPs in FY 2007, which stood at just 60.7%. - Debate on global warming is more and more active in Japan, as it is the host country of the G8 Hokkaido Toyako Summit in July. The Japan Atomic Energy Commission released 'White Paper on Nuclear Energy 2007' in March 2008. In the paper, they first expressed the view that the expansion of the peaceful use of nuclear energy is indispensable. 2. Nuclear overview: a. Energy policy: Electricity share: 25.4% of nuclear. The energy policy of Japan aims at nuclear power generation being maintained at the current level (30 to 40% of the total electricity generation) or increasing even after 2030, for stable energy supply and as a countermeasure against global warming. - Nuclear Fuel Cycle: The active tests at the JNFL reprocessing plant in Rokkasho-mura are in the final phase for commercial operation in 2008. By FY 2010 Plutonium utilization in LWRs in 16 to 18 NPP units. Around FY 2010 Installment of new centrifuges at the uranium enrichment plant at Rokkasho-mura. In FY 2012 Start of commercial operation of MOX fuel fabrication plant. Fast-breeder reactor cycle: Operation of the prototype reactor 'MONJU' has been suspended since a secondary sodium leak in 1995. JAEA (Japan Atomic Energy Agency) completed full-scale remodeling work and is implementing various tests to confirm the capabilities and soundness of MONJU. They aim to start its operation within FY 2008. Around 2025 Building a demonstration FBR. Before 2050 Development of a commercial FBR. - Electricity production (Operating): BWR: 32 units (including 4 units of APWR), PWR: 23 units. - Electricity production

  15. Business ethics in developing countries

    1992-03-01

    Full Text Available Underlying this paper is the conviction that it is of the utmost importance that business ethics should indeed become an integral part of business culture in all, and therefore also in developing countries. It is not to be denied that business ethics has to a much larger extent become pari of the business culture' in developed countries than in developing countries. The primary aim of this paper is to provide an explanation for the fact that business ethics is fighting an uphill battle in becoming pari of the business culture in developing countries. Secondly, a thumbnail sketch is given of the preconditions that have to be fulfilled in order to stimulate the development of a moral business culture in developing countries. In order to achieve these goals I will focus mainly on Africa, and more specifically on South Africa.

  16. Diet in chronic kidney disease in a Mediterranean African country.

    Mediterranean diet is characterized by low to moderate consumption of animal protein and high consumption of fruits, vegetables, bread, beans, nuts, seeds and other cereals. It has been associated with reduced risk of cardiovascular disease. However, it is not suitable for chronic kidney disease because of high potassium intake. Tunisia is an emerging Mediterranean country with limited resources, a high prevalence of chronic hemodialysis treatment and high dialysis expenditures. In order to limit dialysis cost, primary and secondary prevention of chronic renal disease are of paramount importance. In addition to drugs, secondary prevention includes diet measures (e.g. salt diet, protein diet). The aims of diet practice in chronic kidney disease are to slow chronic renal failure progression and to prevent its complications like hyperphosphatemia and hyperkaliemiae. A few decades ago, a Tunisian diet was exclusively Mediterranean, and protein consumption was not excessive. However, today, protein consumption is more comparable to western countries. Salt consumption is also excessive. Some Tunisian diets still include food with high potassium intake, which are not suitable for patients with chronic kidney disease. Therefore, the role of the dietician is extremely important to help calculate and create a dietary regimen tailored to each of our patients. Advice about diets should be adapted to both the patient and population habits to improve adherence rate. As such, the purpose of this article is to provide our own experience regarding medical nutrition therapy in patients with chronic kidney disease in Tunisia, with some changes in food habits. Prevention is far better than treatment. In this perspective, dietary measures must be at the core of our intervention.

  17. The birth rate decline in developing countries.

    Robey, B

    1993-01-01

    Family planning programs historically have played an important role in providing information and counseling and supplying modern methods. Most programs are effective due to socioeconomic development and strong political support. Potential demand for services will be growing. This means that donor agencies must commit additional funding, and users must begin paying or paying more for contraceptives. Services and method choices need to be expanded, and quality of care needs to be improved. Three primary factors will impact on fertility decline: 1) the rate of social development, 2) the speed with which small family norms spread and contraception is adopted, and 3) the facility of private and public suppliers to meet contraceptive demand. Other factors influence reproductive decisions (women's roles and status, economic hardships or opportunities, religion, ethnicity, culture, and tradition). Contraceptive prevalence has increased from under 10% in the 1960s to 38% of all married, reproductive age women in the developing world, excluding China, which has contraceptive prevalence of 72%. Regional differences are wide. In Latin America, contraceptive use averages nearly 60% and ranges from over 50% in 10 countries and below 38% in Bolivia, Guatemala, and Haiti. Contraceptive prevalence is above average in Indonesia (50%), Sri Lanka (62%), and Thailand (68%) and just below average in Bangladesh (40%), India (45%), Philippines (34%), and Vietnam (53%). Sub-Saharan Africa has the lowest prevalence, except for Zimbabwe (45%), Botswana (35%), and Kenya (27%). 80% of current users rely on modern methods. In most surveyed countries, 20-30% of married women have unmet demand. Fertility decline, unmet demand, and contraceptive use have all been affected by the diffusion of ideas about the use of family planning and the small family norm. Innovators are usually high status, educated women, who spread their views to other social groups or geographic areas. The spread can be rapid

  18. Alcohol fuels for developing countries

    Bhattacharya, Partha

    1993-01-01

    The importance of alcohol as an alternative fuel has been slowly established. In countries such as Brazil, they are already used in transport and other sectors of economy. Other developing countries are also trying out experiments with alcohol fuels. Chances of improving the economy of many developing nations depends to a large extent on the application of this fuel. The potential for alcohol fuels in developing countries should be considered as part of a general biomass-use strategy. The final strategies for the development of alcohol fuel will necessarily reflect the needs, values, and conditions of the individual nations, regions, and societies that develop them.

    This paper demonstrates that developing countries differ considerably from their developed counterparts when focus is on the nature and characteristics of short run macroeconomic fluctuations. Cycles are generally shorter, and the stylized facts of business cycles across countries are more diverse...... than those of the rather uniform industrialized countries. Supply-side models are generally superior in explaining changes in output, but a “one-size fits all” approach in formulating policy is inappropriate. Our results also illustrate the critical importance of understanding business regularities...

    Exposure to childhood religious affiliations where the majority of members discourage homosexuality may have negative psychological impacts for Black men who have sex with men. This study tested the hypothesis that exposures to these environments during childhood were associated with adulthood human immunodeficiency virus (HIV)/sexually transmitted infection (STI) behavioral risk and HIV infection, because these exposures influenced HIV/STI risk by undermining race/sexual identity congruence and increasing internalized homophobia and interpersonal anxiety. Structural equation modeling as well as logistic and Poisson regressions were performed using baseline data from HIV Prevention Trials Network 061 (N = 1,553). Childhood religion affiliations that were more discouraging of homosexuality were associated with increased likelihood of HIV infection; however, the association was no longer significant after adjusting for age, income, and education. Having a childhood religion affiliation with high prevalence of beliefs discouraging homosexuality was associated with increased numbers of sexual partners (adjusted odds ratio = 4.31; 95% confidence interval [3.76, 4.94], p < .01). The hypothesized path model was largely supported and accounted for 37% of the variance in HIV infection; however, interpersonal anxiety was not associated with HIV/STI risk behaviors. Structural interventions are needed that focus on developing affirming theologies in religious institutions with Black men who have sex with men congregants. PMID:26758708

  2. Effective anthelmintic therapy of residents living in endemic area of high prevalence for Hookworm and Schistosoma mansoni infections enhances the levels of allergy risk factor anti-Der p1 IgE

    2015-01-01

    Full Text Available In this work were investigated the relationship between Hookworm/Schistosoma mansoni infections and allergy related risk factors in two endemic areas with distinct prevalence of infections and co-infection. The intensity of infections, eosinophilia, allergy risk factors, infections status and anti-Der p1 IgE levels before and 2 years (population 1 and 3 years (population 2 after anthelmintic treatment, were evaluated. It was observed that the population with lower prevalence and intensity of infection (population 2 had lower eosinophils counts (>600/mm3 and higher animal contact than the population with higher parasites intensity (population 1. After anthelmintic treatment the intensity of S. mansoni single infection decreased, but no changes were observed in Hookworm and co-infected individuals. The anthelmintic treatment also enhanced anti-Der p1 IgE optical density in ELISA on the subgroups that became negative for helminth infection regardless of their previous infection condition in population 1. Facing that, we evaluated the anti-Der p1 IgE reactivity index, and the ratio (after/before treatment was significantly higher in patients co-infected before treatment. On the other hand, no association between anti-Der p1 IgE reactivity index and the intensity of infections were observed. In conclusion, effective anthelmintic therapy of subjects from endemic areas with high prevalence of Hookworm and S. mansoni infections enhances anti-Der p1 IgE levels.

    Recommendations for soil-transmitted helminth (STH) control give a key role to deworming of school and pre-school age children with albendazole or mebendazole; which might be insufficient to achieve adequate control, particularly against Strongyloides stercoralis. The impact of preventive chemotherapy (PC) against STH morbidity is still incompletely understood. The aim of this study was to assess the effectiveness of a community-based program with albendazole and ivermectin in a high transmission setting for S. stercoralis and hookworm. Community-based pragmatic trial conducted in Tartagal, Argentina; from 2012 to 2015. Six communities (5070 people) were enrolled for community-based PC with albendazole and ivermectin. Two communities (2721 people) were re-treated for second and third rounds. STH prevalence, anemia and malnutrition were explored through consecutive surveys. Anthropometric assessment of children, stool analysis, complete blood count and NIE-ELISA serology for S. stercoralis were performed. STH infection was associated with anemia and stunting in the baseline survey that included all communities and showed a STH prevalence of 47.6% (almost exclusively hookworm and S. stercoralis). Among communities with multiple interventions, STH prevalence decreased from 62% to 23% (palbendazole and ivermectin is effective for the reduction of STH prevalence and morbidity in communities with high prevalence of hookworm and S. stercoralis.

  5. Progress in the developing countries

    Simnad, M.

    1981-01-01

    Nuclear programmes in selective developing countries are briefly discussed. The oil rich countries of Iraq, Libya and Iran all have reactors on order. Turkey has decided to purchase a PWR from the USSR and Egypt's programme anticipates a capacity of 6600 MWe by 2000. The current projections for India are 6000 MWe by 1990 and 20,000 MWe by 2000. The progress of Pakistan, South Korea and other Asian countries are discussed. The predicted growth in reactors and population in Latin America is considered - 17 reactors presently planned for a population of 340 million and 18-57 possible additions in 2000 for an estimated population of 600 million. The role of the IAEA and experience of some Western countries in technology transfer is discussed with the ambitious Spanish nuclear power programme and the experience of Argentina in purchasing Candu reactors.

  7. Nuclear power in developing countries

    Morrison, R.W.

    1980-01-01

    A few of the essential issues which arise when we consider nuclear power and development together in the context of energy policy are discussed. Ethical concerns must ultimately be expressed through policies and their impact on people. There are ethical issues associated with nuclear power in the developing countries which deserve our attention. Four aspects of the question of nuclear power in developing countries are considered: their energy situation; the characteristics of nuclear power which are relevant to them; whether developing countries will undertake nuclear power programmes; and finally the ethical implications of such programmes. It is concluded that what happens in developing countries will depend more on the ethical nature of major political decisions and actions than on the particular technology they use to generate their electricity.

  10. Automatic and Intentional Number Processing Both Rely on Intact Right Parietal Cortex: A Combined fMRI and Neuronavigated TMS Study

    Cohen Kadosh, Roi; Bien, Nina; Sack, Alexander T.

    2012-01-01

    Practice and training usually lead to performance increase in a given task. In addition, a shift from intentional toward more automatic processing mechanisms is often observed. It is currently debated whether automatic and intentional processing is subserved by the same or by different mechanism(s), and whether the same or different regions in the brain are recruited. Previous correlational evidence provided by behavioral, neuroimaging, modeling, and neuropsychological studies addressing this question yielded conflicting results. Here we used transcranial magnetic stimulation (TMS) to compare the causal influence of disrupting either left or right parietal cortex during automatic and intentional numerical processing, as reflected by the size congruity effect and the numerical distance effect, respectively. We found a functional hemispheric asymmetry within parietal cortex with only the TMS-induced right parietal disruption impairing both automatic and intentional numerical processing. In contrast, disrupting the left parietal lobe with TMS, or applying sham stimulation, did not affect performance during automatic or intentional numerical processing. The current results provide causal evidence for the functional relevance of right, but not left, parietal cortex for intentional, and automatic numerical processing, implying that at least within the parietal cortices, automatic, and intentional numerical processing rely on the same underlying hemispheric lateralization.

    The IRENA Renewable Energy Country Profiles take stock of the latest development of renewable energy in two regions where renewable energy can make a significant contribution to combat climate change and bring modern energy services to everyone: Africa and the Pacific. These two regions are presented separately in this volume and its sister publication. The country profiles combine elements of IRENA analysis with the latest information available from a vast array of sources in order to give a brief yet comprehensive and up-to-date picture of the situation of renewable energy that includes energy supply, electrical capacity, energy access, policies, targets, investment climate, projects and endowment in renewable energy resources. Because of the different timelines of these sources, data presented here refer to years between 2008 and 2012. Data availability also differs from country to country, which makes comparison with a wider regional group possible only for the year for which figures are available for all the members of the group; while this may not be the most recent year, the differences between countries, regions and the world remain striking. The current country profiles are just a starting point; they will be extended upon with new indicators to make them more informative, and maintained as a live product on the IRENA website as a key source of information on renewable energy.

    2016-09-01

    This study aimed to explore the current landscape and identify challenges of pharmacovigilance (PV) among Association of Southeast Asian Nations (ASEAN) countries. This cross-sectional survey collected data from May 2014 to December 2015. Questionnaires seeking to collect information on resources, processes, roles and responsibility, and functions of PV systems were sent to relevant persons in the ASEAN countries. Functions of PV centers were measured using the minimum World Health Organization requirements for a functional national PV system. Performances of PV centers were measured by the following: (1) the indicators related to the average number of individual case safety reports (ICSR); (2) presence of signal detection activities and subsequent action; and (3) contribution to the global vigilance database. Cambodia, Indonesia, Laos, Malaysia, the Philippines, Singapore, Thailand, and Vietnam completed the survey. PV systems in four surveyed countries (Indonesia, Malaysia, Singapore, and Thailand) achieved all aspects of the World Health Organization minimum requirement for a functional national PV system; the remaining countries were deemed to have unclear communication strategies and/or no official advisory committee. Average numbers of recent ICSR national returns ranged from 7 to 3817 reports/year/million population; three countries (Malaysia, Singapore, and Thailand) demonstrated good performance in reporting system and reported signal detection activities and subsequent actions. All participating countries had submitted ICSRs to the Uppsala Monitoring Center during the survey period (2013-2015). Four participating countries had functional PV systems. PV capacity, functionality, and legislative framework varied depending on local healthcare ecosystem networks. Implementing effective communication strategies and/or technical assistance from the advisory committee are needed to strengthen PV in ASEAN. Copyright © 2016 John Wiley & Sons, Ltd. Copyright

  15. Comprehensive taxonomy and worldwide trends in pharmaceutical policies in relation to country income status.

    Maniadakis, N; Kourlaba, G; Shen, J; Holtorf, A

    2017-05-25

    Rapidly evolving socioeconomic and technological trends make it challenging to improve access, effectiveness and efficiency in the use of pharmaceuticals. This paper identifies and systematically classifies the prevailing pharmaceutical policies worldwide in relation to a country's income status. A literature search was undertaken to identify and taxonomize prevailing policies worldwide. Countries that apply those policies and those that do not were then grouped by income status. Pharmaceutical policies are linked to a country's socioeconomics. Developed countries have universal coverage and control pharmaceuticals with external and internal price referencing systems, and indirect price-cost controls; they carry out health technology assessments and demand utilization controls. Price-volume and risk-sharing agreements are also evolving. Developing countries are underperforming in terms of coverage and they rely mostly on restrictive state controls to regulate prices and expenditure. There are significant disparities worldwide in the access to pharmaceuticals, their use, and the reimbursement of costs. The challenge in high-income countries is to maintain access to care whilst dealing with trends in technology and aging. Essential drugs should be available to all; however, many low- and middle-income countries still provide most of their population with only poor access to medicines. As economies grow, there should be greater investment in pharmaceutical care, looking to the policies of high-income countries to increase efficiency. Pharmaceutical companies could also develop special access schemes with low prices to facilitate coverage in low-income countries.

  16. Information-communication technology impact on labor productivity growth of EU developing countries

    Ljiljana Lovrić

    2012-12-01

    Full Text Available The aim of this study is to investigate the ICT impact on labor productivity growth of EU developing countries. Empirical studies of the role of ICT as one of the main determinants of productivity growth, for developing countries have produced disagreement. To help clear up the subject, this paper employs a Generalized Method of Moments (GMM through a dynamic panel data approach on the sample of 25 European developed and developing countries over the period of 2001-2010. The results indicate a positive and significant impact of ICT on labor productivity growth in developed and developing countries, but the terms of impact in developing countries rely on human capital, a contribution of a higher educational level, advanced research qualifications and development activity. Comparing to developed countries, the growth accounting approach indicate that developing countries have similar relative ICT contribution to labor productivity growth, but their average growth rate of labor productivity is 6.8 times higher. The main conclusion is that education, especially of higher levels, is the critical factor of productivity and growth of EU developing countries and that must be taken as development policy implication in these countries.

  17. How and When Do Insects Rely on Endogenous Protein and Lipid Resources during Lethal Bouts of Starvation? A New Application for 13C-Breath testing.

    McCue, Marshall D; Guzman, R Marena; Passement, Celeste A; Davidowitz, Goggy

    2015-01-01

    Most of our understanding about the physiology of fasting and starvation comes from studies of vertebrates; however, for ethical reasons, studies that monitor vertebrates through the lethal endpoint are scant. Insects are convenient models to characterize the comparative strategies used to cope with starvation because they have diverse life histories and have evolved under the omnipresent challenge of food limitation. Moreover, we can study the physiology of starvation through its natural endpoint. In this study we raised populations of five species of insects (adult grasshoppers, crickets, cockroaches, and larval beetles and moths) on diets labeled with either 13C-palmitic acid or 13C-leucine to isotopically enrich the lipids or the proteins in their bodies, respectively. The insects were allowed to become postabsorptive and then starved. We periodically measured the δ13C of the exhaled breath to characterize how each species adjusted their reliance on endogenous lipids and proteins as energy sources. We found that starving insects employ a wide range of strategies for regulating lipid and protein oxidation. All of the insects except for the beetle larvae were capable of sharply reducing reliance on protein oxidation; however, this protein sparing strategy was usually unsustainable during the entire starvation period. All insects increased their reliance on lipid oxidation, but while some species (grasshoppers, cockroaches, and beetle larvae) were still relying extensively on lipids at the time of death, other species (crickets and moth larvae) allowed rates of lipid oxidation to return to prestarvation levels. Although lipids and proteins are critical metabolic fuels for both vertebrates and insects, insects apparently exhibit a much wider range of strategies for rationing these limited resources during starvation.

  18. Moralized Rationality: Relying on Logic and Evidence in the Formation and Evaluation of Belief Can Be Seen as a Moral Issue

    Skitka, Linda J.

    2016-01-01

    In the present article we demonstrate stable individual differences in the extent to which a reliance on logic and evidence in the formation and evaluation of beliefs is perceived as a moral virtue, and a reliance on less rational processes is perceived as a vice. We refer to this individual difference variable as moralized rationality. Eight studies are reported in which an instrument to measure individual differences in moralized rationality is validated. Results show that the Moralized Rationality Scale (MRS) is internally consistent, and captures something distinct from the personal importance people attach to being rational (Studies 1–3). Furthermore, the MRS has high test-retest reliability (Study 4), is conceptually distinct from frequently used measures of individual differences in moral values, and it is negatively related to common beliefs that are not supported by scientific evidence (Study 5). We further demonstrate that the MRS predicts morally laden reactions, such as a desire for punishment, of people who rely on irrational (vs. rational) ways of forming and evaluating beliefs (Studies 6 and 7). Finally, we show that the MRS uniquely predicts motivation to contribute to a charity that works to prevent the spread of irrational beliefs (Study 8). We conclude that (1) there are stable individual differences in the extent to which people moralize a reliance on rationality in the formation and evaluation of beliefs, (2) that these individual differences do not reduce to the personal importance attached to rationality, and (3) that individual differences in moralized rationality have important motivational and interpersonal consequences.

Furthermore, the MRS has high test-retest reliability (Study 4, is conceptually distinct from frequently used measures of individual differences in moral values, and it is negatively related to common beliefs that are not supported by scientific evidence (Study 5. We further demonstrate that the MRS predicts morally laden reactions, such as a desire for punishment, of people who rely on irrational (vs. rational ways of forming and evaluating beliefs (Studies 6 and 7. Finally, we show that the MRS uniquely predicts motivation to contribute to a charity that works to prevent the spread of irrational beliefs (Study 8. We conclude that (1 there are stable individual differences in the extent to which people moralize a reliance on rationality in the formation and evaluation of beliefs, (2 that these individual differences do not reduce to the personal importance attached to rationality, and (3 that individual differences in moralized rationality have important motivational and interpersonal consequences.

  20. How and When Do Insects Rely on Endogenous Protein and Lipid Resources during Lethal Bouts of Starvation? A New Application for 13C-Breath testing.

    Marshall D McCue

    Full Text Available Most of our understanding about the physiology of fasting and starvation comes from studies of vertebrates; however, for ethical reasons, studies that monitor vertebrates through the lethal endpoint are scant. Insects are convenient models to characterize the comparative strategies used to cope with starvation because they have diverse life histories and have evolved under the omnipresent challenge of food limitation. Moreover, we can study the physiology of starvation through its natural endpoint. In this study we raised populations of five species of insects (adult grasshoppers, crickets, cockroaches, and larval beetles and moths on diets labeled with either 13C-palmitic acid or 13C-leucine to isotopically enrich the lipids or the proteins in their bodies, respectively. The insects were allowed to become postabsorptive and then starved. We periodically measured the δ13C of the exhaled breath to characterize how each species adjusted their reliance on endogenous lipids and proteins as energy sources. We found that starving insects employ a wide range of strategies for regulating lipid and protein oxidation. All of the insects except for the beetle larvae were capable of sharply reducing reliance on protein oxidation; however, this protein sparing strategy was usually unsustainable during the entire starvation period. All insects increased their reliance on lipid oxidation, but while some species (grasshoppers, cockroaches, and beetle larvae were still relying extensively on lipids at the time of death, other species (crickets and moth larvae allowed rates of lipid oxidation to return to prestarvation levels. Although lipids and proteins are critical metabolic fuels for both vertebrates and insects, insects apparently exhibit a much wider range of strategies for rationing these limited resources during starvation.

  1. Stepped MS(All) Relied Transition (SMART): An approach to rapidly determine optimal multiple reaction monitoring mass spectrometry parameters for small molecules.

    Multiple reaction monitoring (MRM) is a universal approach for quantitative analysis because of its high specificity and sensitivity. Nevertheless, optimization of MRM parameters remains as a time and labor-intensive task particularly in multiplexed quantitative analysis of small molecules in complex mixtures. In this study, we have developed an approach named Stepped MS(All) Relied Transition (SMART) to predict the optimal MRM parameters of small molecules. SMART requires firstly a rapid and high-throughput analysis of samples using a Stepped MS(All) technique (sMS(All)) on a Q-TOF, which consists of serial MS(All) events acquired from low CE to gradually stepped-up CE values in a cycle. The optimal CE values can then be determined by comparing the extracted ion chromatograms for the ion pairs of interest among serial scans. The SMART-predicted parameters were found to agree well with the parameters optimized on a triple quadrupole from the same vendor using a mixture of standards. The parameters optimized on a triple quadrupole from a different vendor was also employed for comparison, and found to be linearly correlated with the SMART-predicted parameters, suggesting the potential applications of the SMART approach among different instrumental platforms. This approach was further validated by applying to simultaneous quantification of 31 herbal components in the plasma of rats treated with a herbal prescription. Because the sMS(All) acquisition can be accomplished in a single run for multiple components independent of standards, the SMART approach are expected to find its wide application in the multiplexed quantitative analysis of complex mixtures.

    Conclusion: Prevalence of toxoplasmosis among pregnant women in Addis Ababa, Ethiopia is higher than that reported from other countries. Efforts to describe risk factors for toxoplasma infection among Ethiopians should focus in children.

  3. Republic of Venezuela. Country profile.

    Hakkert, R

    1985-06-01

    Venezuela's current economic and demographic situation is described. Venezuela is a major oil country, and the oil industry accounts for 90% of the country's foreign exchange, 70% of the government's revenues, and 15% of the gross domestic product. The economy experienced a sudden and high rate of economic growth in the mid-1970s as a result of high oil prices; however, in recent years, declining oil prices have had a negative effect on the economy. The country is now faced with a serious trade deficit, and the government recently imposed restrictions on imports. Imports in recently years had increased markedly. The emphasis on the oil industry weakened the agricultural sector and, as a result, food imports increased. In addition, the rapid economic growth experienced during the 1970s greatly increased the demand for imported consumer goods. Venezuela has the 4th highest foreign debt in the world (US$35 billion). Despite these problems Venezuela has a relatively high per capita income (US$4,140) and living standard, compared to other countries in the region. Venezuela's total population is 14.6 million, and the population is unevenly distributed. 86% of the population lives in cities of 2500 or more. 37.4% of the population and 70% of the industry is concentrated in the Federal District which contains Caracas, and in the surrounding states of Aragua, Miranda, and Carabobo. This area constitutes only 2.36% of the country's territory. Most of the oil fields are located in the state of Zulia which also contains the country's 2nd largest city (Maracaibo). The country's coastal area contains most of the agricultural lands, and the prairies just south of the coastal mountain ranges are devoted primarily to cattle raising. The remaining 58.2% of the country's territory is essentially jungle and contains only 6.9% of the country's population. The annual population growth rate is 3.11%. Although the rate declined in recent years it is higher than in most of the other

  4. Export opportunities in developing countries

    Sullivan, J.

    1992-01-01

    Developing countries will offer major opportunities to US exporters of energy and related environmental equipment in the next ten years. These opportunities arise because the markets in developing countries will be growing much faster than those in the developed countries during this period, and because these countries will not in most cases have strong domestic manufacturers to compete against. US technologies will help these countries solve their energy, environmental, and economic development problems, and help the US solve its serious trade balance problems. This market will represent over $200 billion between now and 2000. There are, however, many potential problems. These include a lack of focus and coordination among US government trade assistance organizations, a lack of interest on the part of US firms in exporting and an unwillingness to make the needed investments, barriers put up by the governments of potential foreign customers, and strong international competition. This paper describes how the United States Agency for International Development's (A.I.D.) Office of Energy and other US agencies are helping US firms resolve these problems with a comprehensive program of information, trade promotion assistance, and co-funding of feasibility studies. In addition, there are monies available to match unfair concessionary financing offered by our major competitors

  5. Nuclear power for developing countries

    Kendall, J.; Kupitz, J.; Rogner, H. H.

    2000-01-01

    Nuclear power is a proven technology which currently makes a large contribution to the electricity supply in a number of countries and, to a much less extent, to heat supply in some countries. Nuclear power is economically competitive with fossil fuels for base load electricity generation in many countries, and is one of the commercially proven energy supply options that could be expanded in the future to reduce environmental burdens, especially greenhouse gas emissions, from the electricity sector. Over the past five decades, nearly ten thousand reactor-years of operating experience have been accumulated with current nuclear power plants. Building upon this background of success and applying lessons learned from the experience of operating plants, new generations of nuclear power plants have been, or are being developed. Improvements incorporated into these advance designs include features that will allow operators more time to perform equipment protection and safety actions in response to equipment failures and other off normal operating conditions, and that will reduce and simplify the actions required. Great attention is also paid to making new plants simpler to operate, inspect, maintain and repair, thus increasing their overall cost efficiency and their compatibility with the infrastructure of developing countries. The paper provides a discussion of future world energy supply and demand projections, current status and prospects for nuclear power, a short summary of advanced reactor concepts and non-electrical applications of nuclear energy for developing countries, and a review of the role of the IAEA.

  6. Pharmaceutical policies in European countries.

    Barros, Pedro Pita

    2010-01-01

    Pharmaceutical expenditures have an important role in Europe. The attempts to control expenditure have used a wide range of policy measures. We reviewed the main measures adopted by the European Union countries, especially in countries where governments are the largest third-party payers. To complement a literature review on the topic, data was gathered from national reviews of health systems and direct inquiries to several government bodies. Almost all countries regulate prices of pharmaceutical products. Popular policy measures include international referencing to set prices (using as benchmark countries that have set lower prices), internal reference pricing systems to promote price competition in domestic markets, and positive lists for reimbursement to promote consumption of generics (including in some cases substitution by pharmacists of drugs prescribed by physicians). Despite the wide range of policy measures, it is not possible to identify a "silver bullet" to control pharmaceutical expenditures. We also identified two main policy challenges: policy coordination among countries within the European Union to maintain incentives for R&D at the global level, and the development of new relationships with the pharmaceutical industry; namely, the so-called risk-sharing agreements between the pharmaceutical industry and governments/regulators (or large third-party payers).

  7. Impact, regulation and health policy implications of physician migration in OECD countries

    2004-07-01

    . As this is likely to continue, there is a need to create a global framework that enforces physician migration policies that confer benefits on home and host countries. In the long term, OECD countries need to put in place appropriate education and training policies rather than rely on physician migration to address their future needs.

  8. High prevalence of Angiostrongylus cantonensis (rat lungworm on eastern Hawai'i Island: A closer look at life cycle traits and patterns of infection in wild rats (Rattus spp..

    Susan I Jarvi

    Full Text Available The nematode Angiostrongylus cantonensis is a zoonotic pathogen and the etiological agent of human angiostrongyliasis or rat lungworm disease. Hawai'i, particularly east Hawai'i Island, is the epicenter for angiostrongyliasis in the USA. Rats (Rattus spp. are the definitive hosts while gastropods are intermediate hosts. The main objective of this study was to collect adult A. cantonensis from wild rats to isolate protein for the development of a blood-based diagnostic, in the process we evaluated the prevalence of infection in wild rats. A total of 545 wild rats were sampled from multiple sites in the South Hilo District of east Hawai'i Island. Adult male and female A. cantonensis (3,148 were collected from the hearts and lungs of humanely euthanized Rattus rattus, and R. exulans. Photomicrography and documentation of multiple stages of this parasitic nematode in situ were recorded. A total of 45.5% (197/433 of rats inspected had lung lobe(s (mostly upper right which appeared granular indicating this lobe may serve as a filter for worm passage to the rest of the lung. Across Rattus spp., 72.7% (396/545 were infected with adult worms, but 93.9% (512/545 of the rats were positive for A. cantonensis infection based on presence of live adult worms, encysted adult worms, L3 larvae and/or by PCR analysis of brain tissue. In R. rattus we observed an inverse correlation with increased body mass and infection level of adult worms, and a direct correlation between body mass and encysted adult worms in the lung tissue, indicating that larger (older rats may have developed a means of clearing infections or regulating the worm burden upon reinfection. The exceptionally high prevalence of A. cantonensis infection in Rattus spp. in east Hawai'i Island is cause for concern and indicates the potential for human infection with this emerging zoonosis is greater than previously thought.

  9. Community-based short-course treatment of pulmonary tuberculosis in a developing nation. Initial report of an eight-month, largely intermittent regimen in a population with a high prevalence of drug resistance.

    Manalo, F; Tan, F; Sbarbaro, J A; Iseman, M D

    1990-12-01

    A community-based tuberculosis case-finding and short-course chemotherapy program was conducted in a suburb of Manila and featured 1 month of daily isoniazid (INH), rifampin (RIF), ethambutol (EMB), and pyrazinamide (PZA) followed by 7 months of twice-weekly, high dose, directly observed INH + EMB + PZA. Church-affiliated lay workers obtained 1,990 sputum specimens from subjects who complained of chronic cough or wasting symptoms; 207 of the specimens were positive on Ziehl-Neelsen smears. On culture, 176 yielded a significant growth of M. tuberculosis. Of these 176 patients, 144 were selected to enter the study; 10 were lost because of withdrawal or death and four (2.7%) because of drug toxicity. This left 130 patients who were followed long-term. Remarkably, 80% (104) were initially shedding drug-resistant organisms; 26% (34) were resistant to one drug, 30% (40) were resistant to two drugs, and 24% (30) were resistant to three or more drugs. Responses to therapy corresponded closely to the extent of drug resistance: 80% (48 of 60) of patients with drug-susceptible or single resistance had a favorable outcome; 43% (28 of 65) were resistant to two or three drugs, and 0% (0 of 5) of those were resistant to four or more drugs. Notable findings of this study were the success of a community-based program in conducting prolonged, directly observed treatment, the unexpectedly high prevalence of multiple-drug-resistant organisms in this population, and the inadequacy of INH + PZA + EMB during the continuation phase of therapy in this setting.

The aim of this study was to assess the effectiveness of a community-based program with albendazole and ivermectin in a high transmission setting for S. stercoralis and hookworm.Community-based pragmatic trial conducted in Tartagal, Argentina; from 2012 to 2015. Six communities (5070 people were enrolled for community-based PC with albendazole and ivermectin. Two communities (2721 people were re-treated for second and third rounds. STH prevalence, anemia and malnutrition were explored through consecutive surveys. Anthropometric assessment of children, stool analysis, complete blood count and NIE-ELISA serology for S. stercoralis were performed.STH infection was associated with anemia and stunting in the baseline survey that included all communities and showed a STH prevalence of 47.6% (almost exclusively hookworm and S. stercoralis. Among communities with multiple interventions, STH prevalence decreased from 62% to 23% (p<0.001 after the first PC; anemia also diminished from 52% to 12% (p<0.001. After two interventions S. stercoralis seroprevalence declined, from 51% to 14% (p<0.001 and stunting prevalence decreased, from 19% to 12% (p = 0.009.Hookworm' infections are associated with anemia in the general population and nutritional impairment in children. S. stercoralis is also associated with anemia. Community-based deworming with albendazole and ivermectin is effective for the reduction of STH prevalence and morbidity in communities with high prevalence of hookworm and S. stercoralis.

  11. High prevalence of normal tests assessing hypercortisolism in subjects with mild and episodic Cushing's syndrome suggests that the paradigm for diagnosis and exclusion of Cushing's syndrome requires multiple testing.

    Many Endocrinologists believe that a single determination of eucortisolism or a single demonstration of appropriate suppression to dexamethasone excluded Cushing's syndrome, except in what was previously thought to be the rare patient with episodic or periodic Cushing's syndrome. We hypothesize that episodic Cushing's syndrome is relatively common and a single test assessing hypercortisolism may not be sufficient to accurately rule out or diagnose Cushing's syndrome and retrospectively examined the number of normal and abnormal tests assessing hypercortisolism performed on multiple occasions in 66 patients found to have mild and/or episodic Cushing's syndrome compared to a similar group of 54 patients evaluated for, but determined not to have Cushing's syndrome. We found that 65 of the 66 patients with Cushing's syndrome had at least one normal test of cortisol status and most patients had several normal tests. The probability of having Cushing's syndrome when one test was negative was 92% for 23:00 h salivary cortisol, 88% for 24-h UFC, 86% for 24-h 17OHS, and 54% for nighttime plasma cortisol. These results demonstrated that episodic hypercortisolism is highly prevalent in subjects with mild Cushing's syndrome and no single test was effective in conclusively diagnosing or excluding the condition. Rather, the paradigm for the diagnosis should be a careful history and physical examination and in those patients in whom mild Cushing's syndrome/disease is strongly suspected, multiple tests assessing hypercortisolism should be performed on subsequent occasions, especially when the patient is experiencing signs and symptoms of short-term hypercortisolism. © Georg Thieme Verlag KG Stuttgart · New York.

    I examine the relation between bureaucratic corruption ('to get things done') and firm performance in Central and Eastern European countries. While previous re- search relies on data from the BEEPS survey, which suffers from excessive non- reporting of corporate performance, I combine the information on bribery practices from the BEEPS with reliable firm performance data from the Amadeus database. The estimates, identified from within-firm variation, suggest that bureaucratic cor- ruption neg...

  14. Cancer epidemiology in developing countries

    Whelan, S.L.

    2002-01-01

    It is estimated that there were over 10 million new cancer cases in 2000, 5.4 million of them occurring in the developing countries (Parkin et al, 2001). The marked geographical variation in cancer occurrence results in differing therapeutic priorities: North America has more new cancer cases than South-Central Asia, but there are more deaths from cancer in South-Central Asia, reflecting a different pattern of cancer rather than differences in prognosis. Prediction of future trends is difficult, but the impact of population increase and ageing will be significant, with an expected 63% increase in the population of the less developed countries in 50 years. Four sites of cancer namely breast, cervix, colorectal and nasopharyngeal carcinoma are reviewed, looking at their present and possible future importance in the context of developing countries and their aetiology

  15. Energy investment in developing countries

    Rovani, Y.

    1982-01-01

    The developing countries are likely to represent the fastest growing component of the global energy demand over the next two decades. The paper presents considerations based on the World Bank's approach to the energy sector in these countries. It is considered that an accelerated development of conventional indigenous sources of energy is absolutely vital if developing countries are to attain a satisfactory rate of economic growth. The cost of the energy investment, the power sector issues, the optimal use of the resources, the role of the external financing and the need of technical assistance are reviewed. One emphasizes the role of the World Bank in analyzing and preparing projects, and in mobilizing financing from other official and commercial sources

  17. Fundamental research in developing countries

    Moravesik, M.J.

    1964-01-01

    Technical assistance is today a widespread activity. Large numbers of persons with special qualifications in the applied sciences go to the developing countries to work on specific research and development projects, as do educationists on Fulbright or other programmes - usually to teach elementary or intermediate courses. But I believe that until now it has been rare for a person primarily interested in fundamental research to go to one of these countries to help build up advanced education and pure research work. Having recently returned from such an assignment, and having found it a most stimulating and enlightening experience, I feel moved to urge strongly upon others who may be in a position to do so that they should seek similar experience themselves. The first step is to show that advanced education and fundamental research are badly needed in the under-developed countries.

  18. Screening for genital tuberculosis in a limited resource country: case report.

    Namani, Sadie; Qehaja-Buçaj, Emine; Namani, Diellëza

    2017-02-07

    Screening for benign or malignant process of pelvis in young females is a challenge for a physician in a limited resource country. Tuberculosis should be always considered in the differential diagnosis of a pelvic mass in countries with high prevalence of tuberculosis. Negative results of analysis of peritoneal fluid for acid-fast staining, late cultures, and unavailability of new diagnostics methods such as polymerase chain reaction and adenosine deaminase of the aspirated fluid from peritoneal cavity can often result in invasive diagnostic procedures such as laparotomy. We report a case of a 24 year old Albanian unemployed female living in urban place in Kosovo who presented with abdominal pain, loss of appetite, fever, headache, a weight loss, nonproductive cough and menstrual irregularity for three weeks. In this example case, the patient with cystic mass in tubo-ovarial complex and elevated serum cancer antigen 125 levels was diagnosed for genital tuberculosis after performing laparotomy. Caseose mass found in left tubo-ovarial complex and histopathological examination of biopsied tissue were the fastest diagnostic tools for confirming pelvis TB. The Lowenstein-Jensen cultures were positive after six weeks and her family history was positive for tuberculosis. Young females with abdominopelvic mass, ascites, a positive family history for tuberculosis and high serum cancer antigen 125, should always raise suspicion of tuberculosis especially in a limited resource country. A laparoscopy combined with peritoneal biopsy should be performed to confirm the diagnosis as this could lead to a prevention of unnecessary laparotomies.

  19. Policies of access to healthcare services for accompanied asylum-seeking children in the Nordic countries.

    Sandahl, Hinuga; Norredam, Marie; Hjern, Anders; Asher, Henry; Nielsen, Signe Smith

    2013-08-01

    Asylum-seeking children constitute a vulnerable group with high prevalence and risk for mental health problems. The aim of this study was to compare policies of access to healthcare services, including physical examination and screening for mental health problems on arrival, for accompanied asylum-seeking children in the Nordic countries. This study was based on the national reports "Reception of refugee children in the Nordic countries" written by independent national experts for the Nordic Network for Research on Refugee Children, supplemented by information from relevant authorities. In Sweden, Norway and Iceland, asylum-seeking children had access to healthcare services equal to children in the general population. On a policy level, Denmark imposed restrictions on non-acute hospitalisations and prolonged specialist treatments. Regarding health examinations, Sweden deviated from the Nordic pattern by not performing these systematically. In Denmark, Iceland, and some counties in Sweden, but not in Norway, screening for mental health problems was offered to asylum-seeking children. Access to healthcare services for asylum-seeking children differs in the Nordic countries; the consequences of these systematic differences for the individual asylum-seeking child are unknown. For asylum-seeking children, access to healthcare has to be considered in a wider context that includes the core conditions of being an asylum-seeker. A comparative study at policy level needs to be supplemented with empirical follow-up studies of the well-being of the study population to document potential consequences of policies in practice.

  20. Dietary health behaviour and beliefs among university students from 26 low, middle and high income countries.

    Pengpid, Supa; Peltzer, Karl

    2015-01-01

    The aim of this study was to assess the prevalence of six healthy dietary behaviours and associated factors in university students from 26 low, middle and high income countries. In a cross-sectional survey, we used a self-administered questionnaire (largely based on the European Health and Behaviour Survey) among 19503 undergraduate university students (mean age 20.8, Standard deviation=2.8, age range of 16-30 years) from 27 universities in 26 countries. Results indicated that for a total of six healthy dietary behaviours, overall, students scored a mean of 2.8 healthy dietary behaviours. More female than male students indicated healthy dietary behaviours. In multivariate linear regression among men and women, living in an upper middle income or high income country, dieting to lose weight, the high importance of dietary health benefits, high non-organized religious activity, high physical activity and currently a non-tobacco user were associated with the healthy dietary behaviour index. The study found a high prevalence of relatively poor dietary healthy behaviours.
