    Food security is the condition where the food fulfilment is managed well for the country till the individual. Indonesia is one of the country which has the commitment to create the food security becomes main priority. However, the food necessity becomes common thing means that it doesn’t care about nutrient standard and the health condition of family member, so in the fulfilment of food necessity also has to consider the disease suffered by the family member, one of them is pulmonary tuberculosa. From that reasons, this research is conducted to know the factors which influence on household food security status which suffered from pulmonary tuberculosis in the coastal area of Surabaya by using binary logistic regression method. The analysis result by using binary logistic regression shows that the variables wife latest education, house density and spacious house ventilation significantly affect on household food security status which suffered from pulmonary tuberculosis in the coastal area of Surabaya, where the wife education level is University/equivalent, the house density is eligible or 8 m2/person and spacious house ventilation 10% of the floor area has the opportunity to become food secure households amounted to 0.911089. While the chance of becoming food insecure households amounted to 0.088911. The model household food security status which suffered from pulmonary tuberculosis in the coastal area of Surabaya has been conformable, and the overall percentages of those classifications are at 71.8%.

    New Yale isochrones, which have been tested for accuracy (Paper II), provide the means to investigate interesting visual binaries, especially those whose classifications and photometry do not match well (Paper I). Various parameters are deduced for those binaries which fitted the isochrones (e.g., ages, metal abundances, luminosities of peculiar stars); various solutions are systematically developed for those which did not fit, and a likely status of evolution proposed (e.g., duplicity of the components, pre-main-sequence, blue straggler, horizontal branch, optical pair, data inaccuracies). Evolution around the helium flash and diffusion theory are briefly considered. These parameters and statuses provide a wealth of new stellar data and suggestions for further investigation

    Rhythm perception appears to be non-linear as human subjects are better at discriminating, categorizing and reproducing rhythms containing binary vs non-binary (e.a. 1:2 vs 1:3) as well as metrical vs non-metrical (e.a. 1:2 vs 1:2.5) interval ratios. This study examined the representation of binary and non-binary interval ratios within the sensory memory, thus yielding a truly sensory, pre-motor, attention-independent neural representation of rhythmical intervals. Five interval ratios, one binary, flanked by four non-binary ones, were compared on the basis of the MMN they evoked when contrasted against a common standard interval. For all five intervals, the larger the contrast was, the larger the MMN amplitude was. The binary interval evoked a significantly much shorter (by at least 23 ms) MMN latency than the other intervals, whereas no latency difference was observed between the four non-binary intervals. These results show that the privileged perceptual status of binary rhythmical intervals is already present in the sensory representations found in echoic memory at an early, automatic, pre-perceptual and pre-motor level. MMN latency can be used to study rhythm perception at a truly sensory level, without any contribution from the motor system.

    To describe the nutritional status of elderly subjects with mild to moderate Alzheimer's disease. Subjects of both genders (n=40) diagnosed with mild to moderate Alzheimer's disease according to NINCDS-ADRDA criteria, participated in the study. Socioeconomic status, activities of daily life, anthropometric, clinical and dietary profiles were surveyed. Of the total, 65% were female. More than 70% were capable of accomplishing daily activities by themselves. Subjects were eutrophic with a statistically significant difference of the arm circumference between the mild and moderate groups. As for illnesses secondary to Alzheimer's, 52% of the elderly presented hypertension, followed by arthrosis type alterations (17%). The mean consumption of energy and macronutrients in the elderly classified as mild dementia was of 1645 kcal, distributed in 53.7% of carbohydrate, 17.5% of proteins or 0.9 g/kg and 28.8% of lipids. For those classified as moderate dementia it was of 1482 kcal, distributed in 59.3% of carbohydrate, 16.1% of proteins and 24.6% of lipids. In this descriptive study of elderly outpatients with mild and moderate Alzheimer's disease, most presented a nutritional status of eutrophy, with adequate dietary intake of carbohydrates, proteins, lipids and vitamin C, but with low dietary intake of vitamin E.

  5. Status of black-hole-binary simulations for gravitational-wave detection

    2009-01-01

    It is now possible to theoretically calculate the gravitational-wave (GW) signal from the inspiral, merger and ringdown of a black-hole-binary system. The late inspiral, merger and ringdown can be calculated in full general relativity using numerical methods. The numerical waveforms can then be either stitched to inspiral waveforms predicted by approximation techniques (in particular post-Newtonian calculations) that start at an arbitrarily low frequency, or used to calibrate free parameters in analytic models of the full waveforms. In this paper, I summarize the status of numerical-relativity (NR) waveforms that include at least ten cycles of the dominant mode of the GW signal before merger, which should be long enough to produce accurate, complete waveforms for GW observations.

    The available information on the mass of four candidate black holes in X-ray binary systems is summarized; these systems are compared with neutron star binaries with regard to the mass of their components. In mass, the relativistic objects form two distinct groups, neutron stars with masses equal to about 1-2 solar masses and black hole candidates with masses equal to about 10-60 solar masses (there seem to be no intermediate cases), but there is no correlation with the mass of the optical star. Mass exchange between the optical component of a close binary and its neutron star companion would be unlikely to produce a black hole more massive than 5-7 solar masses. Instead, the black holes having masses greater than about 10 solar masses might result from core collapse in stars of initial mass equating 20-100 solar masses through either a rise in the presupernova core mass or weakness of the magnetic field. The (10-30)-fold disparity in the incidence of black holes coupled with OB stars and with radio pulsars could indicate that black holes tend to form in pairs. 36 references

  8. Retrospective Binary-Trait Association Test Elucidates Genetic Architecture of Crohn Disease

    In genetic association testing, failure to properly control for population structure can lead to severely inflated type 1 error and power loss. Meanwhile, adjustment for relevant covariates is often desirable and sometimes necessary to protect against spurious association and to improve power. Many recent methods to account for population structure and covariates are based on linear mixed models (LMMs), which are primarily designed for quantitative traits. For binary traits, however, LMM is a misspecified model and can lead to deteriorated performance. We propose CARAT, a binary-trait association testing approach based on a mixed-effects quasi-likelihood framework, which exploits the dichotomous nature of the trait and achieves computational efficiency through estimating equations. We show in simulation studies that CARAT consistently outperforms existing methods and maintains high power in a wide range of population structure settings and trait models. Furthermore, CARAT is based on a retrospective approach, which is robust to misspecification of the phenotype model. We apply our approach to a genome-wide analysis of Crohn disease, in which we replicate association with 17 previously identified regions. Moreover, our analysis on 5p13.1, an extensively reported region of association, shows evidence for the presence of multiple independent association signals in the region. This example shows how CARAT can leverage known disease risk factors to shed light on the genetic architecture of complex traits. PMID:26833331

    2017-04-01

    The Pneumonia Etiology Research for Child Health (PERCH) study seeks to use modern measurement technology to infer the causes of pneumonia for which gold-standard evidence is unavailable. Based on case-control data, the article describes a latent variable model designed to infer the etiology distribution for the population of cases, and for an individual case given her measurements. We assume each observation is drawn from a mixture model for which each component represents one disease class. The model conisidered here addresses a major limitation of the traditional latent class approach by taking account of residual dependence among multivariate binary outcomes given disease class, hence reducing estimation bias, retaining efficiency and offering more valid inference. Such "local dependence" on each subject is induced in the model by nesting latent subclasses within each disease class. Measurement precision and covariation can be estimated using the control sample for whom the class is known. In a Bayesian framework, we use stick-breaking priors on the subclass indicators for model-averaged inference across different numbers of subclasses. Assessment of model fit and individual diagnosis are done using posterior samples drawn by Gibbs sampling. We demonstrate the utility of the method on simulated and on the motivating PERCH data. © The Author 2016. Published by Oxford University Press. All rights reserved.

    To describe and compare nutritional status, pulmonary function, gender and marital status in patients with chronic obstructive pulmonary disease. Chronic obstructive pulmonary disease is a chronic illness that can lead to poor nutritional status due to an increased energy requirements related to laboured breathing. Inadequate nutritional intake has often been described in this patient group. Nutritional support for patients with chronic obstructive pulmonary disease who suffer from nutritional problems is essential, both for their sense of well-being and for their survival with chronic obstructive pulmonary disease. The study design was descriptive and comparative. Quantitative data collection was carried out among 81 patients with chronic obstructive pulmonary disease (47 women and 34 men) with an average age of 65 years (SD 3·5). The Mini Nutritional Assessment was used to assess nutritional status. Participants who lived alone had worse nutritional status than those who did not live alone, and female participants had worse nutritional status than their male counterparts. No significant correlation was found between pulmonary function and nutritional status. This study contributes knowledge of a potential correlation between nutritional status, gender and marital status in patients with chronic obstructive pulmonary disease. Women with chronic obstructive pulmonary disease may be at an increased risk of malnutrition. Despite the previous results showing malnutrition and underweight to be common, the present study found that many of the participants were overweight, which may reflect a global health trend regardless of disease. Early identification of patients at risk of malnutrition is important. Registered nurses should be aware that patients with chronic obstructive pulmonary disease who are female or who live alone may be at an increased risk of nutritional problems. Patients with chronic obstructive pulmonary disease must be offered information and support

    Thyroid hormones play an important role in the regulation of physiologic processes. Thyroid disease can lead to imbalance in the homeostasis of the body and affect the healing capacity of tissues. However, limited data are available regarding the relationship between thyroid hormone imbalance (thyroid disease) and periodontal health. This review is carried out to summarize the relationship between thyroid disease and periodontal status. PUBMED and MEDLINE searches of both human and animal studies were performed to investigate the relationship between thyroid disease, periodontal status, and dental implants. Results suggest that thyroid diseases may affect the status of periodontal diseases, especially in hypothyroid conditions. The duration from disease onset to treatment of thyroid disorders may be critical, since uncontrolled thyroid disease may result in destruction of the periodontium. Further controlled studies are needed to explore the relationship between thyroid hormone imbalance and periodontal status. Periodontal therapies, including dental implant placement, appear to be safe with no increase in treatment failure, so long as the status of the thyroid gland is controlled.

    To evaluate the current use of adrenalectomy in the treatment of Cushing's disease, we reviewed seven consecutive patients who have undergone adrenalectomy for Cushing's disease at this medical center during 1983 to 1984. Seventy-one percent (5/7) had pituitary, or type I, Cushing's disease, while 29% (2/7) had adrenal, or type II, Cushing's disease from either an adenoma or an adrenocortical carcinoma. Presenting signs and symptoms, either initially or at the time of recurrence, were typical of Cushing's syndrome. Four of five patients with type I disease had recurrent disease after transphenoidal hypophysectomy, bilateral adrenalectomy, or unilateral adrenalectomy. In three of five patients, medical therapy of hypercortisolism was abandoned because of adverse side effects. Preoperative evaluation in all patients included cortisol and ACTH levels, dexamethasone suppression tests, and computerized tomography (both abdominal and head). In patients with a prior history of adrenalectomy, radiocholesterol scans were also performed and were useful. Angiographic procedures were not required in these patients. In patients with type I disease, posterior operative approaches were used. In patients with type II disease, an anterolateral approach was used. Posterolateral incisions are preferred over Hugh-Young incisions and provide better exposure with a reduced risk of poor wound healing. Morbidity and mortality included one death and three nonhealing wounds. In the six surviving patients, symptoms resolved with variable frequency. Findings suggestive of Nelson's syndrome (hyperpigmentation) have occurred in two patients; serial computerized tomographic scans fail to reveal evidence of pituitary tumors

    Blount disease can be defined as idiopathic proximal tibial vara. Several etiologies including the mechanical theory have been described. Obesity is the only causative factor proven to be associated with Blount disease. The aim of this study is to assess if there is an association of vitamin D deficiency and Blount disease. This a retrospective study of preoperative and postoperative patients with Blount disease who were screened for vitamin D deficiency. Patients with genu varum due to confirmed vitamin D deficiency and rickets were excluded. The study patients had the following blood tests done: calcium, phosphate, alkaline phosphatase, parathyroid, and 25-hydroxyvitamin D (25(OH)D) hormones. We recruited 50 patients. The mean age of these patients was 10.4 years (SD±3.88) with average body mass index of 28.7 kg/m (±10.2). Thirty (60%) patients were diagnosed with infantile, 4 (8%) juvenile, and 16 (32%) adolescent Blount disease. Eight (16%) patients were found to be vitamin D deplete (25(OH)D levels children with Blount disease was similar to that of healthy children living in Johannesburg. There is no evidence that vitamin D deficiency is a factor in causing Blount disease. Level III-retrospective study.

    Sheep are the moving banks of shepherds and their economic contribution in terms of meat, wool and skin/hide is immense. Various infectious diseases jeopardize the optimum productivity; among which sheep pox is more important as the disease restricts the export of sheep and their products besides other economic losses. Although, clinical signs are indicative of the disease but a laboratory confirmation is necessary for unequivocal diagnosis and studying epidemiology. The causative agent, sheep pox virus (SPV), is antigenically and genetically closely related to goat pox virus (GPV) and lumpy skin disease virus (LSDV), the other members of the genus capripox virus. In some countries, SPV and GPV are cross infective to small ruminants posing problem in diagnosis and epidemiology. However, recent studies have showed that the viruses are phylogenetically distinct and can be differentiated by molecular tools. Prophylaxis using attenuated vaccines is the choice of control measure as the immunity is long lasting. Detailed information on isolation, identification, pathology, epidemiology, diagnosis and prophylaxis would not only help in updating the knowledge of scientific fraternity but will be useful to the policy makers in order to formulate appropriate measures for control and eradication of the disease. This synthesis is to present an up-to-date review of the disease and its control to provide the reader with an overview of the problem.

    In human genomes, long non-coding RNAs (lncRNAs) have attracted more and more attention because their dysfunctions are involved in many diseases. However, the associations between lncRNAs and diseases (LDA) still remain unknown in most cases. While identifying disease-related lncRNAs in vivo is costly, computational approaches are promising to not only accelerate the possible identification of associations but also provide clues on the underlying mechanism of various lncRNA-caused diseases. Former computational approaches usually only focus on predicting new associations between lncRNAs having known associations with diseases and other lncRNA-associated diseases. They also only work on binary lncRNA-disease associations (whether the pair has an association or not), which cannot reflect and reveal other biological facts, such as the number of proteins involved in LDA or how strong the association is (i.e., the intensity of LDA). To address abovementioned issues, we propose a graph regression-based unified framework (GRUF). In particular, our method can work on lncRNAs, which have no previously known disease association and diseases that have no known association with any lncRNAs. Also, instead of only a binary answer for the association, our method tries to uncover more biological relationship between a pair of lncRNA and disease, which may provide better clues for researchers. We compared GRUF with three state-of-the-art approaches and demonstrated the superiority of GRUF, which achieves 5%~16% improvement in terms of the area under the receiver operating characteristic curve (AUC). GRUF also provides a predicted confidence score for the predicted LDA, which reveals the significant correlation between the score and the number of RNA-Binding Proteins involved in LDAs. Lastly, three out of top-5 LDA candidates generated by GRUF in novel prediction are verified indirectly by medical literature and known biological facts. The proposed GRUF has two advantages over

    To assess the prevalence of (risk of) undernutrition in Dutch elder Parkinson's disease patients as well as it's risk factors. Observational cross-sectional study. An outpatient clinic at the department Neurology of Medical Centre Leeuwarden, a large teaching hospital. 102 outpatients with Parkinson's disease aged 65 years and older were recruited. Data regarding various aspects of undernutrition including socio-demographic aspect, disease characterisitics, nutritional status, appetite and overall-physical and psychological functioning were collected. Undernutrition was diagnosed in 2.0% and 20.5% of the patients were categorized as being at risk of undernutrition. Care dependency and appetite were the two risk factors with the highest predictive value for an unfavorable nutritional status. Of Dutch elderly patients with Parkinson's Disease 22.5% had an unfavourable nutritional status. Dependency and appetite were the two risk factors with the highest predictive value fort his outcome. Because undernutrition can be regarded as a geriatric syndrome a comprehensive nutritional assessment should be done followed by nutritional interventions next to interventions focused on the risk factors. Further studies are needed to evaluate these interventions.

    In recent years, the authors of epidemiological studies have documented that autoimmune diseases are a major problem of modern society and are classified as diseases of civilization. Autoimmune thyroid diseases (ATDs) are caused by an abnormal immune response to autoantigens present in the thyroid gland - they often coexist with other autoimmune diseases. The most common dysfunctions of the thyroid gland are hypothyroidism, Graves-Basedow disease and Hashimoto's disease. Hashimoto's thyroiditis can be the main cause of primary hypothyroidism of the thyroid gland. Anthropometric, biochemical and physicochemical parameters are used to assess the nutritional status during the diagnosis and treatment of thyroid diseases. Patients with hypothyroidism are often obese, whereas patients with hyperthyroidism are often afflicted with rapid weight loss. The consequence of obesity is a change of the thyroid hormones' activity; however, weight reduction leads to their normalization. The activity and metabolic rate of thyroid hormones are modifiable. ATDs are associated with abnormalities of glucose metabolism and thus increased risk of developing diabetes mellitus type 1 and type 2. Celiac disease (CD) also increases the risk of developing other autoimmune diseases. Malnutrition or the presence of numerous nutritional deficiencies in a patient's body can be the cause of thyroid disorders. Coexisting deficiencies of such elements as iodine, iron, selenium and zinc may impair the function of the thyroid gland. Other nutrient deficiencies usually observed in patients suffering from ATD are: protein deficiencies, vitamin deficiencies (A, C, B6, B5, B1) and mineral deficiencies (phosphorus, magnesium, potassium, sodium, chromium). Proper diet helps to reduce the symptoms of the disease, maintains a healthy weight and prevents the occurrence of malnutrition.

    To assess the nutritional status of Alzheimer's disease (AD) patients with no other associated dementia, according to disease stage. Cross-sectional observational study. Neurobehavioral Diseases Outpatient Clinic, Clinical Hospital, Ribeirao Preto Medical School (University of São Paulo). The sample consisted of 36 individuals of both genders with AD diagnosis, and no other associated type of dementia, in various stages of the disease, according to the Clinical Dementia Rating (CDR 0.5-3). Nutritional status was evaluated using the Mini Nutritional Assessment (MNA) and anthropometric measurements such as weight, body mass index (BMI) and arm, waist, abdomen and hip circumferences. In addition, body composition was assessed by bioelectrical impedance analysis (BIA). The mean age of the group was 74.2 ± 10.1 years, 72.2 % of them were women. The MNA showed that most of these individuals were at risk for malnutrition (55.5 %) and many of them (43.7 %) were underweight according to BMI. Data from BIA analysis revealed that 41.7 % of these individuals had a quantity of body fat classified as malnutrition and 11.1 % had a phase angle (PA) below recommended values for age group. There was a negative and significant correlation of lean mass and PA with age, and of global MNA evaluation with CDR, as well as a positive correlation of MNA total score with fat mass and BMI. Worse classifications of nutritional status obtained by MNA scores were also observed in the more severe stages of the disease, according to the CDR. Patients with AD are mostly elderly with changes in body composition that are typical of aging, with signs of peripheral malnutrition and preservation of abdominal fat. However, greater impairment of general nutritional status was observed in the more advanced stages of AD, creating a situation of greater vulnerability for these patients.

    Malnutrition has been found in up to 24% of patients with Parkinson's disease; dopaminergic drugs might impair nutritional status. We evaluated the association of nutritional status with the use of dopaminergic agents. We analyzed data from 75 elderly patients with Parkinson's disease attending a geriatric day hospital. Nutritional status was assessed by the Mini Nutritional Assessment (MNA). Dopaminergic drugs were normalized for weight. In linear regression, total levodopa (l-dopa) equivalent daily dose (LEDD) was associated with worse MNA (B = -0.14, 95% CI = -0.26--0.02; P = 0.019). This association remained significant only for l-dopa (B = -0.19, 95% CI = -0.32--0.52; P = 0.007), but not dopaminergic agent dosages. Increasing l-dopa dosages were associated with increasing probability of risk of malnutrition (P for trend = 0.049).

    Susan Secore

    Full Text Available Clostridium difficile infections (CDI are a leading cause of nosocomial diarrhea in the developed world. The main virulence factors of the bacterium are the large clostridial toxins (LCTs, TcdA and TcdB, which are largely responsible for the symptoms of the disease. Recent outbreaks of CDI have been associated with the emergence of hypervirulent strains, such as NAP1/BI/027, many strains of which also produce a third toxin, binary toxin (CDTa and CDTb. These hypervirulent strains have been associated with increased morbidity and higher mortality. Here we present pre-clinical data describing a novel tetravalent vaccine composed of attenuated forms of TcdA, TcdB and binary toxin components CDTa and CDTb. We demonstrate, using the Syrian golden hamster model of CDI, that the inclusion of binary toxin components CDTa and CDTb significantly improves the efficacy of the vaccine against challenge with NAP1 strains in comparison to vaccines containing only TcdA and TcdB antigens, while providing comparable efficacy against challenge with the prototypic, non-epidemic strain VPI10463. This combination vaccine elicits high neutralizing antibody titers against TcdA, TcdB and binary toxin in both hamsters and rhesus macaques. Finally we present data that binary toxin alone can act as a virulence factor in animal models. Taken together, these data strongly support the inclusion of binary toxin in a vaccine against CDI to provide enhanced protection from epidemic strains of C. difficile.

    Full Text Available Newcastle disease (ND is one of the most important diseases that affect birds; the epizootic nature of the disease has caused severe economic losses in the poultry industry worldwide. In this experiment ND virus (NDV was inactivated by two different chemicals binary ethylenimine (BEI and formaldehyde. Formaldehyde was used at 0.1%, while BEI was used at concentrations of 1 to 4 mM. NDV inactivation with BEI was done in various incubation temperatures and periods and the best result (30 °C, 4 mM BEI and 21 hrs treatment used as an experimental vaccine. Prepared inactivated NDV vaccines and a commercial vaccine were tested for their efficiency in generating humoral immune response in different groups of specific pathogen free (SPF chicks. Test groups received 0.2 ml formaldehyde inactivated NDV (NDVF, BEI inactivated NDV (NDVEI and Razi institute produced NDV vaccine (NDVR subcutaneously respectively. HI Log 2 total mean titer of NDVEI group (8.42 ± 0.12 were significantly higher than NDVF (7.64 ± 0.16 and NDVR (7.86 ± 0.11 groups (p<0.05. BEI-inactivated vaccine gave higher antibody titers than formaldehyde-inactivated vaccine and preserves both structural integrity and antigenicity of the virus. Thus, it might be possible to use these compounds as an inactivator agent for commercial NDV inactivated vaccines in future.

    Nutrition is among the most important factors influencing coronary artery disease. Here we aimed to study the nutritional status of patients with and without coronary artery disease (CAD). We performed a cross-sectional study on 600 patients referred to a cardiology clinic with the signs of ACS. The patients were then classified in to two groups (CAD group and the normal group) based on angiographic findings. The amount of nutritional profile was questioned from all participants. Men were more often diagnosed with CAD compared to women (198/362 vs. 102/238; P nutritional factors predicting CAD. White mean and type of tea were the most important predictors of CAD. Dietary prevention strategies from childhood could prevent early CAD.

    2012-01-01

    The population of patients with chronic kidney disease is aging, and approximately 50% of those starting renal replacement therapy are older than 65 years. Aging poses challenges to maintaining the nutritional status of these patients. As patients get older, purchasing and preparing food may become difficult if the patient is not supported by relatives or social workers. In addition, appetite may decrease as a result of depression. Furthermore, intercurrent illnesses may become more frequent, leading to changes in nutrient requirements. Mobility and cognitive function often decline in elderly patients and the combination of these factors may result in malnutrition. Since malnutrition has been demonstrated to impact on survival in dialysis patients of all ages, appropriate attention to nutritional status and its management is essential in the elderly patient, both in the predialysis phase and on dialysis. This article reviews the issues associated with the maintenance of good nutrition in elderly patients and describes the potential causes of malnutrition. It also reviews the nutrient requirements of older dialysis patients (which differ somewhat from those of younger patients) as well as the assessment of their nutritional status. Finally, recommendations for the management of nutrition in the elderly patient are discussed.

  12. Health Status Measurement Instruments in Chronic Obstructive Pulmonary Disease

    1997-01-01

    Full Text Available Chronic obstructive pulmonary disease (COPD is associated with primary respiratory impairment, disability and handicap, as well as with secondary impairments not necessarily confined to the respiratory system. Because the primary goals of managing patients with COPD include relief of dyspnea and the improvement of health-related quality of life (HRQL, a direct measurement of HRQL is important. Fourteen disease-specific and nine generic questionnaires (four health profiles and five utility measures most commonly used to measure health status in patients with COPD were reviewed. The measures were classified according to their domain of interest, and their measurement properties - specifications, validity, reliability, responsiveness and interpretability - were described. This review suggests several findings. Currently used health status instruments usually refer to the patients’ perception of performance in three major domains of HRQL - somatic sensation, physical and occupational function, and psychological state. The choice of a questionnaire must be related to its purpose, with a clear distinction being made between its evaluative and discriminative function. In their evaluative function, only a few instruments fulfilled the criteria of responsiveness, and the interpretability of most questionnaires is limited. Generic questionnaires should not be used alone in clinical trials as evaluative instruments because of their inability to detect change over time. Further validation and improved interpretability of existing instruments would be of greater benefit to clinicians and scientists than the development of new questionnaires.

    The cohort-level risk of Huntington disease (HD) is related to the age and symptom level of the cohort, but this relationship has not been made precise. To predict the evolving likelihood of carrying the Huntington disease (HD) gene for at-risk adults using age and sign level. Using data from adults with early signs and symptoms of HD linked to information on genetic status, we use Bayes' theorem to calculate the probability that an undiagnosed individual of a certain age and sign level has an expanded CAG repeat. Both age and sign levels have substantial influence on the likelihood of HD onset, and the probability of eventual diagnosis changes as those at risk age and exhibit (or fail to exhibit) symptoms. For example, our data suggest that in a cohort of individuals age 26 with a Unified Huntington's Disease Rating Scale (UHDRS) motor score of 7-10 70% of them will carry the HD mutation. For individuals age 56, the same motor score suggests only a 40% chance of carrying the mutation. Early motor signs of HD, overall and the chorea subscore, were highly predictive of disease onset at any age. However, body mass index (BMI) and cognitive performance scores were not as highly predictive. These results suggest that if researchers or clinicians are looking for early clues of HD, it may be more foretelling to look at motor rather than cognitive signs. Application of similar approaches could be used with other adult-onset genetic conditions.

    Infectious bursal disease virus (IBDV) is the aetiological agent of the acute and highly contagious infectious bursal disease (IBD) or "Gumboro disease". IBD is one of the economically most important diseases that affects commercially produced chickens worldwide. Along with strict hygiene management of poultry farms, vaccination programmes with inactivated and live attenuated viruses have been used to prevent IBD. Live vaccines show a different degree of attenuation; many of them may cause bursal atrophy and thus immunosuppression with poor immune response to vaccination against other pathogens and an increase in vulnerability to various types of infections as possible consequences. Depending on their intrinsic characteristics or on the vaccination procedures, some of the vaccines may not induce full protection against the very virulent IBDV strains and antigenic variants observed in the last three decades. As chickens are most susceptible to IBDV in their first weeks of life, active immunity to the virus has to be induced early after hatching. However, maternally derived IBDV-specific antibodies may interfere with early vaccination with live vaccines. Thus new technologies and second-generation vaccines including rationally designed and subunit vaccines have been developed. Recently, live viral vector vaccines have been licensed in several countries and are reaching the market. Here, the current status of IBD vaccines is discussed.

    Full Text Available The objective of this study was to determine the frequency of occurrence and to characterize the typology of dysfluencies in individuals with Parkinson’s disease (PD, including the variables age, gender, schooling, disease duration, score on the Hoehn and Yahr scale and cognitive status (score on Mini-Mental State Examination. A cross-sectional study of a sample comprising 60 adults matched for gender, age and schooling was conducted. Group I comprised 30 adults with idiopathic PD, and Group II comprised 30 healthy adults. For assessment of fluency of speech, subjects were asked to utter a narrative based on a sequence of drawings and a transcription of 200 fluent syllables was performed to identify speech dysfluencies. PD patients exhibited a higher overall number of dysfluencies in speech with a large number of atypical dysfluencies. Additionally, results showed an influence of the variables cognitive status, disease duration and age on occurrence of dysfluencies.

    The achievement of a normal nutritional status, that is a normal body composition and a normal pattern of growth, is a cornerstone in the management of children with chronic kidney disease (CKD). Protein-energy wasting (PEW) which indicates the state of decreased body protein mass and fuel reserves (body protein and fat mass), is a common condition in this population, and a source of morbidity and mortality. For the diagnosis of this condition, a lot of methods have been proposed, but due to the clinical characteristics of children with CKD, the intrinsic limits of the available indices and some methodological issues concerning published pediatric studies, none of these parameters could be considered as the gold standard. Given these limitations, a general consensus exists according to which only the combination of more indices integrated in a multidisciplinary approach can give the idea of the individual nutritional status. Among these indices, recent guidelines recommend dietary intake (by means of 3-day diary or 24-hour recall), anthropometric parameters (weight, height, height velocity, body mass index, head circumference) and, only for adolescent on hemodialysis, normalized protein catabolic rate as the most accurate ones. Other methods, such as mid-arm anthropometry, bioimpedance analysis, biochemical indices, and dual-energy X-ray absorptiometry could certainly help in the nutritional evaluation, taking into account the advantages and drawbacks of each method.

    The cognitive status of patients with Parkinson's disease (PD) who developed pathological gambling (PG) during dopamine replacement therapy has been poorly explored. We compared clinical and cognitive features of 21 consecutive PD patients with active PG (PD-PG) versus 42 PD controls of similar disease duration without any impulse control disorder. All patients underwent full neuropsychological testing to evaluate executive and other frontal lobe-related functions, attention, learning and memory, language, visuospatial abilities and neuropsychiatric status [using Geriatric Depression Scale (GDS) and Neuropsychiatric Inventory (NPI)] as well as the South Oaks Gambling Screen Scale (SOGS). PD-PG were younger (60.4 vs. 64.9, p = 0.01) and more frequently of male gender (85 vs. 57%, p = 0.02). The two groups did not differ in medication dosages and kind of dopamine agonist. PD-PG had higher MMSE (29.1 vs. 27.4, p = 0.02) and performed better at Rey Auditory Verbal learning Test (45.9 vs. 40.4, p = 0.04), verbal phonemic fluencies (38.7 vs. 31.8, p = 0.02), verbal semantic fluencies (44.9 vs. 37.4, p = 0.01) and attentive matrices (47.6 vs. 43.5, p = 0.05) while the remaining cognitive performances were comparable to controls. Moreover, based on the NPI, PD-PG had higher aggressiveness, irritability, disinhibition and eating disorders than controls. In conclusion the occurrence of PG in our cohort of patients with PD was associated with preserved executive functions.

    Studies have shown that various antioxidants are decreased in different age-related degenerative diseases and thus, oxidative stress would have a central role in the pathogenesis of many disorders that involve neuronal degeneration, including Alzheimer's disease (AD). The present study aimed to assess the nutritional status of Se in AD patients and to compare with control subjects with normal cognitive function. The case-control study was carried out on a group of elderly with AD (n 28) and compared with a control group (n 29), both aged between 60 and 89 years. Se intake was evaluated by using a 3-d dietary food record. Se was evaluated in plasma, erythrocytes and nails by using the method of hydride generation atomic absorption spectroscopy. Deficient Se intake was largely observed in the AD group. AD patients showed significantly lower Se levels in plasma, erythrocytes and nails (32.59 microg/l, 43.74 microg/l and 0.302 microg/g) when compared with the control group (50.99 microg/l, 79.16 microg/l and 0.400 microg/g). The results allowed us to suggest that AD has an important relation with Se deficiency.

    The objective of this study is to identify, in a sample of very mild Alzheimer disease (AD) patients, factors associated with disease progression. The authors followed 160 AD patients from a multicenter cohort with a Clinical Dementia Rating (CDR) of 0.5, corresponding to very mild AD but with impairment insufficient to be classified as dementia. Patients with disease progression were defined as those with CDR> or =1 at 1 year; those with no progression (stable) remained at CDR 0.5. The baseline characteristics of these 2 groups of patients were compared in search of predictors of progression. After a 1-year follow-up, 84 (52.5%) of the patients remained stable, CDR 0.5; 76 (47.5%) progressed to a CDR score > or =1. A baseline lower nutritional status assessed by the Mini Nutritional Assessment [odds ratio 0.80, 95% confidence interval (0.68-0.94), P=0.007] and a lower cognitive performance on the Alzheimer Disease Assessment Scale [odds ratio 1.22, 95% confidence interval (1.07-1.39), P=0.003] were found as predictors of progression. The results suggest that clinical assessment of nutritional status, along with cognitive data, may help detect patients at risk of progression in very early AD. Nutritional assessment should therefore form part of clinical evaluation of patients with AD at an early stage of the disease.

    Full Text Available We review the current status of studies of the coalescence of binary neutron star systems. We begin with a discussion of the formation channels of merging binaries and we discuss the most recent theoretical predictions for merger rates. Next, we turn to the quasi-equilibrium formalisms that are used to study binaries prior to the merger phase and to generate initial data for fully dynamical simulations. The quasi-equilibrium approximation has played a key role in developing our understanding of the physics of binary coalescence and, in particular, of the orbital instability processes that can drive binaries to merger at the end of their lifetimes. We then turn to the numerical techniques used in dynamical simulations, including relativistic formalisms, (magneto-hydrodynamics, gravitational-wave extraction techniques, and nuclear microphysics treatments. This is followed by a summary of the simulations performed across the field to date, including the most recent results from both fully relativistic and microphysically detailed simulations. Finally, we discuss the likely directions for the field as we transition from the first to the second generation of gravitational-wave interferometers and while supercomputers reach the petascale frontier.

    Full Text Available Abstract Background There had been conflicting reports with levels of markers of iron metabolism in HIV infection. This study was therefore aimed at investigating iron status and its possible mediation of severity of HIV- 1 infection and pathogenesis. Method Eighty (80 anti-retroviral naive HIV-1 positive and 50 sero-negative controls were recruited for the study. Concentrations of serum total iron, transferrin, total iron binding capacity (TIBC, CD4+ T -lymphocytes, vitamin C, zinc, selenium and transferrin saturation were estimated. Results The mean CD4+ T-lymphocyte cell counts, serum iron, TIBC, transferrin saturation for the tests and controls were 319 ± 22, 952 ± 57 cells/μl (P 4+ T-lymphocyte cell count had a positive correlation with levels of vitamin C (r = 0.497, P Conclusion It could be inferred that derangement in iron metabolism, in addition to oxidative stress, might have contributed to the depletion of CD4+ T cell population in our subjects and this may result in poor prognosis of the disease.

    We aimed to assess levels of education attained, employment, and marital status of adults diagnosed with inflammatory bowel diseases (IBD) during childhood or adolescence, compared with healthy individuals in Canada. We performed a cross-sectional study of adults diagnosed with IBD in childhood or adolescence at Children's Hospital in Winnipeg, Manitoba from January 1978 through December 2007. Participants (n = 112) answered a semi-structured questionnaire on educational achievements, employment, and marital status. Patients were matched for age and sex with random healthy individuals from the 2012 Canadian Community Health Survey (controls, 5 per patient). Conditional binary logistic regression and random-effects ordinal logistic regression models were used for analysis. Patients were followed for a mean duration of 14.3 years (range, 3.1-34.5 years). Persons with IBD were more likely to earn more money per annum and attain a post-secondary school degree or receive a diploma than controls (odds ratio, 1.72; 95% confidence interval, 1.13-2.60; P education levels than individuals without IBD. This observation should provide reassurance to children with IBD and their parents. ClinicalTrials.gov number: NCT02152241. Copyright © 2017 AGA Institute. Published by Elsevier Inc.

    Full Text Available Arteriosclerosis is the basis of all cardiovascular diseases. Numerous risk factors lead to the rise of malignant and cardiovascular diseases. Those are: elevated artery blood pressure, raised plasma cholesterol and triglycerides, low level of HDL-cholesterol, smoking, diabetes mellitus, diet, lack of physical exercises, heredity, stress, gender.The aim of the study was to compare the lipid status of patients with cardiovascular disease or malignancy.The database of the biochemical laboratory and oncology counseling unit of the "Ostrog Clinic" was used. The method of random sample was used and patients (n=29 of both genders were selected, who were at the age of 40 to 47, with cardiovascular diseases, and had significant occlusive coronary disease, which required operation or surgical revascularization procedure. The patients were classified in two groups: G1 (n=14 with statin therapy and G2 (n=15 without statin therapy. Both groups were statistically compared with a group of female patients (n=30 with breast cancer, who were between 37 and 69 years of age. Control group comprised 25 healthy subjects. Standard statistical methods were used for processing the lipid status parameters, namely: the arithmetic mean, standard deviation SDn and SDn-1, correlation coefficient, post hock test and a single factor analysis of variance.The results obtained have pointed to the existence of a marked hyperlipoproteinemia type 4 in the group of cardiovascular patients who did not use statin (G2. In G2, higher levels of cholesterol, LDL-cholesterol and plasma triglycerides in comparison with the control and G1, while the value of HDL-cholesterol was within the range of referent values. The obvious suppressing effect of statin on cholesterol and LDL-cholesterol was observed in G1.

    Full Text Available Dentist and oral health screening may be the latest weapon in identifying persons at risk of cardiovascular disease. Oral infections, specifically periodontitis, may confer independent risks for different systemic conditions. The risk factors associated with cardiovascular diseases also suggest that the relationship between periodontal disease and diabetes works in both ways. The aim of this study was to support and strengthen the association and relationship between oral hygiene status of individuals with cardiovascular diseases and its associated risk factors. A simple random sampling was carried out in 200 inhabitants of Western Utter Pradesh, India. An oral health visit and examination was made for an equal number of males and females of different age groups with cardiovascular diseases. Evaluation of the oral status was made by means of an oral hygiene index, community periodontal index of treatment needs and loss of attachment. Evaluation of oral status in patients with cardiovascular diseases and in the control group has shown a statistically significant low level of oral health in patients with cardiovascular diseases as compared to control. Prevalence of systemic diseases in different age groups significantly correlated with the prevalence of severe periodontal diseases. Treating gum disease may reduce the risk of heart disease and improve health outcomes for patients with periodontal disease and vascular heart problems.

    To determine the association between social, economic and behavioural risk factors and national prevalences of: oral cancer, dental caries (12-year-olds) and destructive periodontal disease (35-44-year-olds). Sources for the social and economic parameters were the UN Development Program; the behavioural risk factors' source was the World Health Organization, the UN Food and Agricultural Organization and the World Atlas of History. Oral diseases data came from UICC Globocan and the World Health Organization databases. Data were extracted by hand from official publications. Data were synthesized and analyzed in sequence using SPSS, Pearson's correlation coefficient and multiple regression analyses. There is a discernable association between the three oral diseases and the variables selected, which varies in strength, being strongest for chronic destructive periodontitis and weakest for oral cancer. Dental caries lies in between. The degree to which variables account for differences in the three oral diseases between the countries studied is striking, being insignificant for oral cancer incidence, modest for oral cancer mortality, stronger for dental caries and strongest for destructive periodontal disease. Removing variables with strong co-linearity with the Human Development Index has little effect on the regression coefficients.

    Tandel, G M; John, K Riji; Rosalind George, M; Prince Jeyaseelan, M J

    The intensification of aquaculture has been unique in showing the overwhelming changes in global food production in the last 100 years. Presently, it is playing a vital role in the economies of several countries. Conversely, it is also to be noted that the progression of aquaculture has been the foundation of anthropogenic alteration of a gigantic hierarchy and hence not astonishingly, it resulted in spread and emergence of an increasing group of new unknown diseases. In India, Penaeus monodon, black tiger shrimp was previously the foremost-cultivated shrimp species. Subsequently in 2008, the American white leg shrimp Litopenaeus vannamei has effectively replaced it. The change in dominant species has affected disease concerns in India as well as in world shrimp aquaculture. White spot syndrome virus (WSSV) is the most deleterious for both species. Hepatopancreatic parvovirus (HPV), Monodon baculovirus (MBV) and Infectious hypodermal and hematopoietic necrosis virus (IHHNV) are the other significant infectious agents of P. monodon and L. vannamei. An emerging disease of loose shell syndrome (LSS) was already reported from India during late 1998. A more recent disease of L. vannamei in India is monodon slow growth syndrome (MSGS), a component of which seems to be Laem-Singh virus (LSNV). Thus, most of the information in this review relates to new emerging pathogens that threaten the cultivation shrimp industry in India.

    Full Text Available OBJECTIVES: This study investigated the serum 25-hydroxyvitamin D levels of patients with Behcet's Disease. DESIGN AND METHODS: Thirty-two patients with Behcet's Disease and 31 matched healthy controls were enrolled in this study. The erythrocyte sedimentation rate (ESR and the levels of C-reactive protein (CRP, serum 25-hydroxyvitamin D, calcium (Ca, phosphate (P, and total alkaline phosphatase (ALP were measured in both groups. RESULTS: There were no significant differences between the two groups regarding demographic data. The serum 25-hydroxyvitamin D levels of patients and controls were 13.76 (range: 4.00-35.79 and 18.97 (range: 12.05-36.94 ng/ml, respectively. In patients with Behcet's Disease, 25-hydroxyvitamin D values were significantly lower than those of the healthy controls (p<0.001. Serum Ca, P, and ALP levels were similar in both groups. Serum ESR and CRP levels were significantly higher in patients than controls (p<0.05. There was no correlation between 25-hydroxyvitamin D levels and age, body mass index (BMI, disease duration, ESR, or CRP levels. Multivariate regression analysis parameters showed that smoking, alcohol intake, and use of colchicine were the main predictors of 25-hydroxyvitamin D levels. Of the parameters studied, the largest impact was due to colchicine therapy (p<0.001. We did not find a significant relationship between the use of corticosteroids and 25-hydroxyvitamin D levels. CONCLUSION: Our results suggest that serum 25-hydroxyvitamin D levels are decreased in patients with Behcet's Disease. Smoking, alcohol intake, and use of colchicine appear to affect vitamin D levels.

  12. Adult lactose digestion status and effects on disease

    Science.gov (United States)

    Szilagyi, Andrew

    2015-01-01

    BACKGROUND: Adult assimilation of lactose divides humans into dominant lactase-persistent and recessive nonpersistent phenotypes. OBJECTIVES: To review three medical parameters of lactose digestion, namely: the changing concept of lactose intolerance; the possible impact on diseases of microbial adaptation in lactase-nonpersistent populations; and the possibility that the evolution of lactase has influenced some disease pattern distributions. METHODS: A PubMed, Google Scholar and manual review of articles were used to provide a narrative review of the topic. RESULTS: The concept of lactose intolerance is changing and merging with food intolerances. Microbial adaptation to regular lactose consumption in lactase-nonpersistent individuals is supported by limited evidence. There is evidence suggestive of a relationship among geographical distributions of latitude, sunhine exposure and lactase proportional distributions worldwide. DISCUSSION: The definition of lactose intolerance has shifted away from association with lactose maldigestion. Lactose sensitivity is described equally in lactose digesters and maldigesters. The important medical consequence of withholding dairy foods could have a detrimental impact on several diseases; in addition, microbial adaptation in lactase-nonpersistent populations may alter risk for some diseases. There is suggestive evidence that the emergence of lactase persistence, together with human migrations before and after the emergence of lactase persistence, have impacted modern-day diseases. CONCLUSIONS: Lactose maldigestion and lactose intolerance are not synonymous. Withholding dairy foods is a poor method to treat lactose intolerance. Further epidemiological work could shed light on the possible effects of microbial adaptation in lactose maldigesters. The evolutionary impact of lactase may be still ongoing. PMID:25855879

    2009-12-01

    The seroprevalence of anti-HAV (hepatitis A virus) has been decreasing in Korea. The decrease in HAV infection in young adults has resulted in the reduction of individuals with protective antibody and an increase in hepatitis A in the adult population. The increase in HAV infection in adults will have an impact on the magnitude and severity of the disease. In Korea, symptomatic hepatitis A has been gradually increasing since the mid-1990s, with a tendency toward an increase in mean age and disease severity. The endemic genotype of HAV in Korea has been changing from genotype IA alone to a mixture of genotype IA and IIIA. Therefore, preventive measures including universal vaccination in infants and active immunization of the adult population should be considered.

    The human major histocompatibility complex is a multi-gene ~4 Mb of DNA including the highly polymorphic HLA genes which are fundamental in effecting a healthy immune response. Detailed knowledge of the structure and function of HLA genes and their alleles and HLA proteins and their allotypes has rapidly evolved because of their role in clinical transplantation. A significant additional finding is the association or linkage of a wide range of diseases with HLA. We review the function of HLA and the history of disease association studies and focus on specific informative examples in the context of recent genome-wide screening analyses.

    The prevalence of gastroesophageal reflux disease (GERD) and the incidence of some of its complications have risen strikingly over the last few decades. With the increase in our understanding of the pathophysiology of GERD along with the development of proton pump inhibitors, the diagnostic and therapeutic approaches to GERD have changed dramatically over the past decade. However, GERD still poses a problem to many clinicians since the spectrum of the disease has evolved to encompass more challenging presentations such as refractory GERD and extra-esophageal manifestations. The aim of this article is to provide a review of available current translational research on GERD. This review includes acid pocket, ambulatory pH monitoring, impedance pH monitoring, mucosa impedance, and high resolution manometry. This article discusses current translational research on GERD.

    Full Text Available Objective: The aim of the present study was to examine the periodontal condition of an adult population in three isolated regions in Greece and to determine the association of periodontal disease with several demographic, behavioral and environmental factors.Materials and Methods: The study population consisted of 640 individuals, aged 20to69 years from three isolated regions. The following indices were assessed: Pocket Depth (PD, Clinical Attachment Level (CAL, Dental Plaque, Calculus and Bleeding on Probing (BOP. Statistical analysis was accomplished by multiple linear regression model which was used to assess the association between the mean clinical attachment loss and clinical, demographic and behavioral parameters.Results: The samples of the study showed high levels of dental plaque, dental calculus and BOP. The final multivariate model showed that age (p=0.000, gender (p=0.016 and presence of calculus (p=0.000 were associated with the mean clinical attachment loss. Age (p=0.000, gender (p=0.000 and dental plaque (p=0.027 were associated with gingival recession, while age (p=0.018 and gender (p=0.000 were associated with probing depth. Bleeding on probing, dental plaque, toothbrush frequency, level of education, tobacco consumption and reasons for dental visits were not associated with the mean clinical attachment loss.Conclusion: Periodontal disease consists of a complicated destructive condition of the Periodontal tissue with a.multi-factorial etiology. Oral hygiene instructions and a regular dental follow-up could play a significant role in the prevention of periodontal disease.Key Words: Periodontal Disease; Epidemiology; Risk Factors

    2010-01-01

    Full Text Available There are approximately 7.8 million people in Latin America, including Chile, who suffer from Chagas disease and another 28 million who are at risk of contracting it. Chagas is caused by the flagellate protozoan Trypanosoma cruzi. It is a chronic disease, where 20%-30% of infected individuals develop severe cardiopathy, with heart failure and potentially fatal arrhythmias. Currently, Chagas disease treatment is more effective in the acute phase, but does not always produce complete parasite eradication during indeterminate and chronic phases. At present, only nifurtimox or benznidazole have been proven to be superior to new drugs being tested. Therefore, it is necessary to find alternative approaches to treatment of chronic Chagas. The current treatment may be rendered more effective by increasing the activity of anti-Chagasic drugs or by modifying the host's immune response. We have previously shown that glutathione synthesis inhibition increases nifurtimox and benznidazole activity. In addition, there is increasing evidence that cyclooxygenase inhibitors present an important effect on T. cruzi infection. Therefore, we found that aspirin reduced the intracellular infection in RAW 264.7 cells and, decreased myocarditis extension and mortality rates in mice. However, the long-term benefit of prostaglandin inhibition for Chagasic patients is still unknown.

  20. Biomarkers of psychiatric diseases: current status and future prospects.

    Science.gov (United States)

    Kalia, Madhu; Costa E Silva, Jorge

    2015-03-01

    Abnormal behavior and disturbed cognition, often assumed to represent psychiatric illness, may actually result from some form of occult organic brain disease that can be detected by means of one or more biomarkers. This truth was discovered more than a century ago by Aloysius Alzheimer, a German psychiatrist and neuropathologist. As a psychiatrist, he described the behavioral manifestations of "senile dementia" in a 51-year-old female; as a neuropathologist, he was the first to recognize the significance of the senile plaques and neurofibrillary tangles found in her brain after her death at age 55 years. It was Alzheimer who made the connection between these "biomarkers" and the symptoms of the increasingly prevalent disease that now bears his name. In recent years, the search for psychiatry-relevant biomarkers of major depression, schizophrenia, bipolar disease, and other important psychiatric/neuropsychiatric disorders has intensified. Biomarkers in psychiatry and neuropsychiatry have the potential of clarifying the etiology of an ambiguous clinical presentation-making it possible, for example, to detect underlying differences between psychological maladies that have confusingly similar symptoms. In addition, attempts are now being made to classify mental disorders on the basis of biomarkers. Biomarkers may also disclose the presence of a previously unsuspected physical explanation for behavior(s) originally presumed to be "psychiatric" in origin. Although clinically usable biomarkers in the diagnosis and treatment of mental illness await validation, candidate genomic biomarkers and protein profiling of candidate biomarkers in psychiatry are rapidly gaining ground as areas of interest, with considerable future potential. This review considers biomarker-related issues germane to psychiatry and neuropsychiatry in the context of new data that can be used to tailor therapies to the individual psychiatric patient.

    2012-01-01

    Full Text Available The research was undertaken to assess the health status of the fish eaters and non-fish eaters and assess the prevalence of nutritional and life style diseases among them. Totally 340 subjects, 173 fish eaters and 167 non fish eaters, in the age group of 20 to 40 years, both male and female subjects were selected. A sub sample of 10 fish eaters and 10 non - fish eaters were selected for the estimation of blood lipid profile. The demographic details, nutritional status, prevalence of nutritional and life style diseases and health status were evaluated. The results brought out the beneficial effects of consuming fish. Fish eaters had good nutritional status, normal blood lipid values and anthropometric measurements which were in the normal range. It was alarming to note that the total cholesterol, low density lipoprotein and very low density lipoprotein were more than the recommended values for the non-fish eating group. Prevalence of non communicable diseases showed that fish eaters had fewer incidences of these diseases while the prevalence of non communicable diseases was more among non-fish eaters. Consumption of fish was beneficial in protecting health and preventing degenerative diseases. The study brought out the beneficial effect of fish consumption.

    Health-related quality of life (HRQOL) is an important outcome in dialysis care. Previous research has related protein-energy nutritional status to generic HRQOL domains, but it is still not clear as to how it relates to HRQOL domains that are unique to hemodialysis patients. Therefore, our aim was to study the relation between protein-energy nutritional status and kidney disease-specific HRQOL domains in hemodialysis patients. This was a cross-sectional study. This study was performed at multiple centers. We evaluated the first 590 hemodialysis patients who had enrolled in the Convective Transport Study. We measured protein-energy nutritional status by using the Subjective Global Assessment, albumin, normalized nitrogen appearance, creatinine, body mass index, and cholesterol. HRQOL was assessed by using the Kidney Disease Quality Of Life-Short Form. In all, 83% of the cohort was found to be well-nourished on the basis of the Subjective Global Assessment. Multiple nutritional parameters were positively related to the physical summary of generic HRQOL and to the following kidney disease-specific HRQOL scales: the effects of the kidney disease on daily life, the burden of the kidney disease, and overall health. This study showed that, even in predominantly well-nourished hemodialysis patients, protein-energy nutritional status was significantly related to kidney disease-specific HRQOL.

    Chronic obstructive pulmonary disease (COPD) is a progressive disease with a prevalence that increases with the aging of the subject. It presents a high prevalence of comorbidities, such as cognitive decline, which is gaining great clinical relevance in recent years. Factors such as pulmonary function, hypoxemia, hypercapnia or exacerbations contribute to the decline of cognitive functions. The nutritional status has been added to these factors as contributing to cognitive function decline when presenting in COPD. To evidence the relationship between cognitive decline, nutritional status and the clinical profile of patients admitted because of an acute exacerbation of COPD (AECOPD). 110 subjects hospitalized because of COPD, divided in two groups according to their nutritional status and assessment of cognitive decline at admittance, nutritional status and clinical profile. Significant differences between groups concerning nutritional status in anthropometric variables (sex and IMC), functional ability (Barthel index and Daily Life Activities Scale), quality of life (Euroqol- 5D y SGRQ), sleep quality (Pittsburgh), mood (HAD) and cognitive decline (MoCa attention, MoCa abstraction). (pCognitive function is affected in COPD patients with an altered nutritional status when compared to those with a normal nutritional status. The nutritional decline is a factor contributing to the impairment of cognitive functions in this kind of patients, particularly a decline in attention and abstraction ability.

Cross-sectional study. Alzheimer Center, SS. Trinità Hospital, Cagliari (Italy). 83 free-living patients (29 men, 54 women) with mild-moderate Alzheimer's disease, aged 66 to 96 years, and 91 age-matched controls (37 men and 54 women). Nutritional status was evaluated by anthropometry (weight, height, waist and upper arm circumferences, triceps skinfold; body mass index, BMI; arm muscle area, AMA); Mini Nutritional Assessment, MNA®; bioelectrical impedance vector analysis, BIVA. Psycho-functional status was assessed by the Mini Mental State Examination (MMSE), Geriatric Depression Scale (GDS), Activities of Daily Living (ADL), and Instrumental Activities of Daily Living (IADL). Compared to the control groups, patients with Alzheimer's disease had a worse psycho-functional and nutritional status. BIVA detected lower body cell mass in Alzheimer's patients with respect to controls (men: T²= 23.4; women: T²=27.3; pnutritional status in Alzheimer's disease.

  5. Nutritional status in chronic obstructive pulmonary disease: role of hypoxia.

    Raguso, Comasia A; Luthy, Christophe

    2011-02-01

    In patients with chronic obstructive pulmonary disease (COPD), malnutrition and limited physical activity are very common and contribute to disease prognosis, whereas a balance between caloric intake and exercise allows body weight stability and muscle mass preservation. The goal of this review is to analyze the implications of chronic hypoxia on three key elements involved in energy homeostasis and its role in COPD cachexia. The first one is energy intake. Body weight loss, often observed in patients with COPD, is related to lack of appetite. Inflammatory cytokines are known to be involved in anorexia and to be correlated to arterial partial pressure of oxygen. Recent studies in animals have investigated the role of hypoxia in peptides involved in food consumption such as leptin, ghrelin, and adenosine monophosphate activated protein kinase. The second element is muscle function, which is strongly related to energy use. In COPD, muscle atrophy and muscle fiber shift to the glycolytic type might be an adaptation to chronic hypoxia to preserve the muscle from oxidative stress. Muscle atrophy could be the result of a marked activation of the ubiquitin-proteasome pathway as found in muscle of patients with COPD. Hypoxia, via hypoxia inducible factor-1, is implicated in mitochondrial biogenesis and autophagy. Third, hormonal control of energy balance seems to be affected in patients with COPD. Insulin resistance has been described in this group of patients as well as a sort of "growth hormone resistance." Hypoxia, by hypoxia inducible factor-1, accelerates the degradation of tri-iodothyronine and thyroxine, decreasing cellular oxygen consumption, suggesting an adaptive mechanism rather than a primary cause of COPD cachexia. COPD rehabilitation aimed at maintaining function and quality of life needs to address body weight stabilization and, in particular, muscle mass preservation. Copyright © 2011 Elsevier Inc.

    Low vitamin D status has been associated with cardiovascular disease (CVD) and mortality primarily in selected groups, smaller studies, or with self-reported vitamin D intake. We investigated the association of serum vitamin D status with the incidence of a registry-based diagnosis of ischemic...... heart disease (IHD), stroke, and all-cause mortality in a large sample of the general population. A total of 9,146 individuals from the two population-based studies, Monica10 and Inter99, were included. Measurements of serum 25-hydroxyvitamin D at baseline were carried out using the IDS ISYS immunoassay...

    We aimed to assess whether partially reversible and fixed airway obstructions are associated with different health status profiles of chronic obstructive pulmonary disease (COPD) patients. We characterized health status profiles of outpatients over 64 years suffering from COPD with fixed (n = 181) or partially reversible obstruction (n = 95) and from chronic bronchitis with forced expiratory volume in the first second (FEV1) > 69% of that predicted (n = 109) on the basis of the Saint George Respiratory Questionnaire (SGRQ) and indexes assessing cognitive (Mini Mental State), affective (15-item Geriatric Depression Scale) and physical status (Index of Barthel, six-minute walking test) and quality of sleep (Index of disturbed sleep). The degree of group-specificity of health status profiles was assessed by discriminant analysis. The 54.1% of COPD patients with partially reversible obstruction were recognized to have a distinctive health status profile characterized by a moderate to severe impairment of all components ('Symptoms', 'Activity', 'Impacts') of the SGRQ and of select indexes of performance. According to logistic regression analysis, this health status profile was associated with FEV respiratory drugs (OR: 2.28, CI: 1.46-3.57) and living alone (OR: 2.01, 95% CI: 1.3-2.29). COPD patients with fixed obstruction had a very heterogeneous health status. Research is needed to verify whether the unfavorable health status profile typical of a subset of COPD patients is associated with a distinctive prognosis and can be improved by dedicated therapeutic interventions.

    Full Text Available The therapeutic target in Crohn's disease (CD has been raised to the achievement of mucosal healing. Although effective treatments that target cytokines and other molecules has been widely used for CD, intestinal strictures are still a major cause of surgery. Endoscopic balloon dilation (EBD is known to be an effective and safe intervention for intestinal strictures in CD. Since frequent intestinal resection often results in short bowel syndrome and can decrease the quality of life, EBD can help avoid surgery. EBD with a conventional colonoscope for Crohn's strictures of the colon and ileo-colonic anastomosis has established efficacy and safety. In addition, EBD using balloon-assisted enteroscopy has recently been applied for small bowel Crohn's strictures. Although the evidence is not strong, EBD may become an alternative to surgery in small bowel strictures in CD. EBD and other new methods such as self-expanding stent implantation for Crohn's strictures may be useful and safe; however, it is important to address several issues regarding these interventions and to establish a protocol for combined therapies.

    Full Text Available The co-existence of high prevalence of vitamin D inadequacy among Canadians and high prevalence of systematic autoimmune rheumatic diseases (SARDs raise the question on relationship between the two situations. Objective: To determine vitamin D status in known cases of common SARDs and compare to those with non-autoimmune diseases; further, to evaluate the impact of vitamin D on disease activity in rheumatoid arthritis (RA cases. Methods: In a retrospective case-control study design, we evaluated 116 patients in a community clinic classified in two groups, Control group: patients with non-rheumatic disease (n = 56, and Case group: those with rheumatic diseases (n = 60. We compared plasma vitamin D status (25(OHD, indicators of disease activity and other potential confounders. Further, we determined factors associated with disease activity in RA cases. Results: The plasma 25(OHD was significantly lower in Case group (64.8 ± 29.8 compared to Control group (86.8 ± 37.7. High number of SARDs outpatients 56% had considerably low plasma 25(OHD concentration. RA cases with low plasma 25(OHD had over five times higher risk of disease activity (OR = 5.15 95% CI 1.16, 22.9; p = 0.031. Conclusion: Inadequate vitamin D status in SARDs cases, along with considerably strong association with disease activity in RA cases, indicate the need for proper evaluation of vitamin D status in this clinical population. Moreover, appropriate training should be given to the patients to ensure the intake of the recommended amount of vitamin D per day through diet or supplement.

    Cardiovascular diseases (CVDs) are among the top health problems of the Chinese population. Although mounting evidence suggests that early childhood health status has an enduring effect on late life chronic morbidity, no study so far has analyzed the issue in China. Using nationally representative data from the 2013 China Health and Retirement Longitudinal Study (CHARLS), a Probit model and Two-Stage Residual Inclusion estimation estimator were applied to analyze the relationship between childhood health status and adulthood cardiovascular disease in rural China. Good childhood health was associated with reduced risk of adult CVDs. Given the long-term effects of childhood health on adulthood health later on, health policy and programs to improve the health status and well-being of Chinese populations over the entire life cycle, especially in persons' early life, are expected to be effective and successful.

    2018-01-01

    Full Text Available Disease maps are important tools in the management of disease. By communicating risk, disease maps can help raise awareness of disease and encourage farmers and veterinarians to employ best practice to eliminate the spread of disease. However, despite the importance of disease maps in communicating risk and the existence of various online disease maps, there are few studies that explicitly examine their usability. Where disease maps are complicated to use, it seems that they are unlikely to be used effectively. The paper outlines an attempt to create an open access, online, searchable map of incidents of bovine tuberculosis in England and Wales, and analyzes its usability among veterinarians. The paper describes the process of creating the map before describing the results of a series of usability trials. Results show the map to score highly on different measures of usability. However, the trials also revealed a number of social and technical limitations and challenges facing the use of online disease maps, including reputational dangers, role confusion, data accuracy, and data representation. The paper considers the challenges facing disease maps and their potential role in designing new methodologies to evaluate the effectiveness of disease prevention initiatives.

    2014-01-01

    High-quality person-centred care for people with Parkinson's disease (PwPD) and their families relies on identifying and addressing factors that specifically impact on quality of life (QoL). Deficits in executive functions (EF) are common in Parkinson's disease, but their impact on PwPD and their caregivers is not well understood. The present study evaluated how EF contributes to QoL and health status for the PwPD and caregiver burden. Sixty-five PwPD completed measures of QoL, health status and EF, and 50 caregivers rated the EF of the PwPD and their own burden. Multiple regression analyses examined predictors of QoL (general life, health and movement disorders domains), health status and caregiver burden. Quality of life in the health and movement disorders domains was best explained by caregiver-rated EF, whereas QoL in the general life domain was best explained by level of depression. Health status was predicted by self-rated EF, with an objective EF measure also included in the regression model. Caregiver burden was best explained by caregiver-rated EF and disease severity, with general cognition and other factors also included in the regression model. Executive functions-related behavioural problems may contribute to QoL and health status in PwPD and affect caregiver burden. The findings support the view that the concepts of subjective QoL and self-assessed health status are only partially related and should not be seen as identical. Adequate strategies to reduce the impact of EF deficits are needed as this may have the potential to improve QoL in PwPD. Copyright © 2013 John Wiley & Sons, Ltd.

    Full Text Available CONTEXT: Malnutrition is frequently observed in inpatients with malignant diseases and may contribute to longer hospital stays. OBJECTIVE: To compare the nutritional status, lymphocyte count, hemoglobin values and length of hospital stay of patients with and without malignant diseases. METHODS: This comparative study assessed indicators of nutritional status, namely body mass index, recent weight loss, lymphocyte count, hemoglobin and length of hospital stay, of 928 surgical patients with and without malignant diseases (50.2% females and 49.8% males. The chi-square test was used to compare proportions and the Mann-Whitney test was used to compare continuous measurements between two groups. The significance level was set at 5%. RESULTS: Patients with malignant diseases had longer hospital stays (P<0.0001, furthermore, a higher percentage of patients with malignant diseases had body mass index <18.5 (P<0.0001 and experienced recent weight changes (P<0.0002. Lymphocyte count also differed statistically between the groups (P = 0.0131, which lower levels were identified among patients with malignant diseases. CONCLUSION: The lymphocyte count, hemoglobin values and weight loss are important findings of nutritional depletion in patients with malignant diseases.

    measure of the data heterogeneity, has been used to modify formulae for individual sample size estimation. However, subgroups of animals sharing common characteristics, may exhibit excessively less or more heterogeneity. Hence, sample size estimates based on the ICC may not achieve the desired precision...... and power when applied to these groups. We propose the use of the variance partition coefficient (VPC), which measures the clustering of infection/disease for individuals with a common risk profile. Sample size estimates are obtained separately for those groups that exhibit markedly different heterogeneity......, thus, optimizing resource allocation. A VPC-based predictive simulation method for sample size estimation to substantiate freedom from disease is presented. To illustrate the benefits of the proposed approach we give two examples with the analysis of data from a risk factor study on Mycobacterium avium...

    2015-01-01

    Background Evaluations of the impact of interventions for resource allocation purposes commonly focus on health status. There is, however, also concern about broader impacts on wellbeing and, increasingly, on a person's capability. This study aims to compare the impact on health status and capability of seven major health conditions, and highlight differences in treatment priorities when outcomes are measured by capability as opposed to health status. Methods The study was a cross-sectional four country survey (n = 6650) of eight population groups: seven disease groups with: arthritis, asthma, cancer, depression, diabetes, hearing loss, and heart disease and one health population ‘comparator’ group. Two simple self-complete questionnaires were used to measure health status (EQ-5D-5L) and capability (ICECAP-A). Individuals were classified by illness severity using condition-specific questionnaires. Effect sizes were used to estimate: (i) the difference in health status and capability for those with conditions, relative to a healthy population; and (ii) the impact of the severity of the condition on health status and capability within each disease group. Findings 5248 individuals were included in the analysis. Individuals with depression have the greatest mean reduction in both health (effect size, 1.26) and capability (1.22) compared to the healthy population. The effect sizes for capability for depression are much greater than for all other conditions, which is not the case for health. For example, the arthritis group effect size for health (1.24) is also high and similar to that of depression, whereas for the same arthritis group, the effect size for capability is much lower than that for depression (0.55). In terms of severity within disease groups, individuals categorised as 'mild' have similar capability levels to the healthy population (effect sizes population (≥0.4). Conclusion Significant differences exist in the relative effect sizes across diseases

    The most common indication for treating patients with peripheral arterial disease is to improve their health status: their symptoms, function, and quality of life. Quantifying health status requires a valid, reproducible, and sensitive disease-specific measure. The Peripheral Artery Questionnaire (PAQ) is a 20-item questionnaire developed to meet this need by quantifying patients' physical limitations, symptoms, social function, treatment satisfaction, and quality of life. Psychometric and clinical properties of the PAQ were evaluated in a prospective cohort study of 44 patients undergoing elective percutaneous peripheral revascularization. To establish reproducibility, 2 assessments were performed 2 weeks apart and before revascularization. The change in scores before and 6 weeks after revascularization were used to determine the instruments' responsiveness and were compared with the Short Form-36 and the Walking Impairment Questionnaire. A series of cross-sectional analyses were performed to establish the construct validity of the PAQ. The 7 domains of the PAQ were internally reliable, with Cronbach alpha = 0.80 to 0.94. The test-retest reliability analyses revealed insignificant mean changes of 0.6 to 2.3 points (P = not significant for all). Conversely, the change after revascularization ranged from 13.7 to 41.9 points (P PAQ to clinical improvement. The PAQ Summary Scale was the most sensitive of all scales tested. Construct validity was established by demonstrating correlations with other measures of patient health status. The PAQ is a valid, reliable, and responsive disease-specific measure for patients with peripheral arterial disease. It may prove to be a useful end point in clinical trials and a potential aid in disease management.

    It is difficult for current simulation tools to simulate sequence data in a pre-specified pedigree structure and pre-specified affection status. Previously, we developed a flexible tool, SeqSIMLA2, for simulating sequence data in either unrelated case-control or family samples with different disease and quantitative trait models. Here we extended the tool to efficiently simulate sequences with multiple disease sites in large pedigrees with a given disease status for each pedigree member, assuming that the disease prevalence is low.

    Little is known about the role of socioeconomic status in relation to Parkinson's disease (PD) risk, and no study has investigated whether the impact of socioeconomic status on all-cause mortality differs between individuals with and without PD.In this population-based prospective study, over 4.6 million Swedish inhabitants who participated in the Swedish census in 1980 were followed from 1981 to 2010. The incidence rate of PD and incidence rate ratio were estimated for the association between socioeconomic status and PD risk. Age-standardized mortality rate and hazard ratio (HR) were estimated for the association between socioeconomic status and all-cause mortality for individuals with and without PD.During follow-up, 66,332 incident PD cases at a mean age of 76.0 years were recorded. Compared to individuals with the highest socioeconomic status (high nonmanual workers), all other socioeconomic groups (manual or nonmanual and self-employed workers) had a lower PD risk. All-cause mortality rates were higher in individuals with lower socioeconomic status compared with high nonmanual workers, but relative risks for all-cause mortality were lower in PD patients than in non-PD individuals (e.g., for low manual workers, HR: 1.12, 95% confidence interval [CI]: 1.09-1.15 for PD patients; HR: 1.36, 95% CI: 1.35-1.36 for non-PD individuals).Individuals with lower socioeconomic status had a lower PD incidence compared to the highest socioeconomic group. Lower socioeconomic status was associated with higher all-cause mortality among individuals with and without PD, but such impact was weaker among PD patients.

    Oliveira, Aparecida de; Mancini Filho, Jorge

    2005-04-01

    To assess the nutritional status and lipid profile of postmenopausal women with coronary heart disease. A retrospective cross-sectional study was conducted with information obtained from the medical records of 217 women on the occasion of their first visit to the InCor Nutrition Outpatient Care Clinic. The data referred to the patients' nutritional status, body mass index, use of lipid-lowering medication, and serum lipid levels (cholesterol and fractions). The mean age was 60.98 +/- 9.23 years, and obesity prevailed in 56% of the patients. The use of lipid-lowering drugs was observed in 73% of the population. In regard to lipid profile, 56% had adequate serum levels of HDL-C. The nutritional status was inadequate due to the prevalence of obesity, which results in the appearance of other chronic diseases, such as dyslipidemias. Although the dosages of the lipid-lowering drugs used were not assessed, their use by the population studied did not seem to be favorable, because high levels of total cholesterol and LDL-C were observed, and those high levels in that condition are strongly related to the occurrence of cardiovascular diseases. Multidisciplinary action in the form of programs to promote women's health is required, comprising preventive aspects related to coronary heart disease, to improve the quality of life in that population.

    A Mendelian randomization (MR) analysis is performed to analyze the causal effect of an exposure variable on a disease outcome in observational studies, by using genetic variants that affect the disease outcome only through the exposure variable. This method has recently gained popularity among epidemiologists given the success of genetic association studies. Many exposure variables of interest in epidemiological studies are time varying, for example, body mass index (BMI). Although longitudinal data have been collected in many cohort studies, current MR studies only use one measurement of a time-varying exposure variable, which cannot adequately capture the long-term time-varying information. We propose using the functional principal component analysis method to recover the underlying individual trajectory of the time-varying exposure from the sparsely and irregularly observed longitudinal data, and then conduct MR analysis using the recovered curves. We further propose two MR analysis methods. The first assumes a cumulative effect of the time-varying exposure variable on the disease risk, while the second assumes a time-varying genetic effect and employs functional regression models. We focus on statistical testing for a causal effect. Our simulation studies mimicking the real data show that the proposed functional data analysis based methods incorporating longitudinal data have substantial power gains compared to standard MR analysis using only one measurement. We used the Framingham Heart Study data to demonstrate the promising performance of the new methods as well as inconsistent results produced by the standard MR analysis that relies on a single measurement of the exposure at some arbitrary time point. © 2016 WILEY PERIODICALS, INC.

    PURPOSE: It is well known that a significant proportion of heart failure patients (10-44 %) do not show improvement in symptoms or functioning from cardiac resynchronization therapy (CRT), yet no study has examined patient-reported health status trajectories after implantation. METHODS: A cohort...... of 139 patients with a CRT-defibrillator (70 % men; age 65.7 ± 10.1 years) completed the Kansas City Cardiomyopathy Questionnaire (KCCQ) prior to implantation (baseline) and at 2, 6, and 12-14 months post-implantation. Latent class analyses were used to identify trajectories and associates of disease......-specific health status over time. RESULTS: All health status trajectories showed an initial small to large improvement from baseline to 2-month follow-up, whereafter most trajectories displayed a stable pattern between short- and long-term follow-up.

    Abstract Background: Previous studies have investigated associations between apolipoprotein E (APOE)-ɛ4 allele status and acetylcholinesterase inhibitor treatment response in patients with Alzheimer’s disease. The ability to draw definitive conclusions regarding the effect of APOE-ɛ4 genotype on treatment response has been hindered by inconsistent results among studies and methodological limitations that restrict interpretation of study findings. Objective: To determine whether APOE-ɛ4 carrier status influences the magnitude of change in 13-item Alzheimer’s Disease Assessment Scale−Cognitive Subscale (ADAS-cog) score associated with acetylcholinesterase inhibitor treatment (i.e., donepezil). Methods: Analyses were performed using pooled data from the donepezil and placebo treatment arms of three consecutive, similarly designed, 12-week, multi-national, randomized clinical studies that enrolled patients with mild-to-moderate Alzheimer’s disease. Correlations between APOE-ɛ4 carrier status and ADAS-cog scores were evaluated using analysis of covariance. Results: No appreciable interaction between donepezil response and APOE-ɛ4 carrier status or copy number was detected. Both carriers and non-carriers of APOE-ɛ4 who received donepezil experienced significant improvements from baseline in ADAS-cog score versus placebo (p donepezil treatment group was – 2.95 for APOE-ɛ4 carriers and – 4.09 for non-carriers (p = 0.23). In contrast, non-carriers of APOE-ɛ4 in the placebo treatment group exhibited a greater improvement from baseline versus carriers (–2.38 versus – 0.60, p = 0.05). Conclusion: Within this population, APOE genotype had no statistically significant effect on cognitive response to donepezil treatment; however, APOE-ɛ4 allele status was associated with a difference in the magnitude of the change in ADAS-cog of placebo-treated patients.

    Full Text Available Central nervous system (CNS inflammatory demyelinating diseases (IDDs are a group of disorders with different aetiologies, characterized by inflammatory lesions. These disorders include multiple sclerosis (MS, neuromyelitis optica spectrum disorder (NMOSD, and idiopathic transverse myelitis (ITM. Differential diagnosis of the CNS IDDs still remains challenging due to frequent overlap of clinical and radiological manifestation, leading to increased demands for new biomarker discovery. Since cerebrospinal fluid (CSF metabolites may reflect the status of CNS tissues and provide an interfacial linkage between blood and CNS tissues, we explored multi-component biomarker for different IDDs from CSF samples using gas chromatography mass spectrometry-based metabolite profiling coupled to multiplex bioinformatics approach. We successfully constructed the single model with multiple metabolite variables in coordinated regression with clinical characteristics, expanded disability status scale, oligoclonal bands, and protein levels. The multi-composite biomarker simultaneously discriminated four different immune statuses (a total of 145 samples; 54 MS, 49 NMOSD, 30 ITM, and 12 normal controls. Furthermore, systematic characterization of transitional metabolic modulation identified relapse-associated metabolites and proposed insights into the disease network underlying type-specific metabolic dysfunctionality. The comparative analysis revealed the lipids, 1-monopalmitin and 1-monostearin were common indicative for MS, NMOSD, and ITM whereas fatty acids were specific for the relapse identified in all types of IDDs.

    Atopic dermatitis is one of the most common pediatric chronic inflammatory skin diseases, and certain food allergens and nutrients are closely related to the development and severity of atopic dermatitis. While avoidance of the causative foods is considered the mainstay of treatment, unverified excessive restriction might induce unnecessary limitations in the food intake, consequently leading to nutritional deficiencies and poor growth. This study aimed to identify the characteristics and nutrient intake status in children with atopic dermatitis and to investigate the effects of individualized nutrition intervention. We retrospectively reviewed electronic medical records of 77 pediatric patients with atopic dermatitis who received 4 months of individualized nutrition intervention combined with an elimination diet. The patient characteristics, nutrient intake status, and clinical status were examined before and after the intervention. Before the intervention, 5 children had a weight for height z-score below -2.0, and 48.1% had experienced food restriction; these children showed a significantly higher SCORing of Atopic Dermatitis index than those without experiences, with the number of restricted foods before the intervention positively correlating with the disease severity. The intakes of n-6 and n-3 fatty acids, calcium, folate, and vitamin D were lower than the recommended nutrient intakes for Koreans. After the intervention, the weight for height z-score of 35 children was significantly increased and their SCORing of Atopic Dermatitis index was significantly reduced (pnutrition intervention appears useful for alleviating the severity of atopic dermatitis and improving the growth status by improving the nutrient intake.

    To study nutritional status in chronic obstructive pulmonary disease (COPD) in relation to the serum content of adipose tissue hormones. Ninety-four patients with Stages II and III COPD and 20 gender- and age-matched healthy non-smoking volunteers were examined. Interviews, analysis of laboratory data, enzyme immunoassay, and somatometry were made. The patients with COPD are characterized by the development of malnutrition, even in the absence of body weight loss and in the presence of normal body mass index (BMI) with predominant lean body mass (LBM) loss, normal serum concentrations of adipose tissue hormones. With more advanced COPD and a worse nutritional status, the level of leptin decreases and that of adiponectin increases. The content of adiponectins is closely related to the indicators of nutritional status, mainly to the value of body weight loss, BMI, LBM, absolute blood lymphocyte count, and degree of malnutrition. The COPD patients with emphysema show the most pronounced changes in nutritional status and higher adiponectin levels. An integrated assessment of the degree of protein-energy malnutrition and measurement of the level of adipose tissue hormones should be made when nutritional status is studied in patients with COPD.

    Malnutrition is common in infants and children with congenital heart disease (CHD). Cardiac surgery has improved patient survival and nutritional status. To evaluate the impact of cardiac surgery on nutritional status of pediatric patients with CHD. A prospective cohort study was conducted in pediatric patients with CHD, admitted for cardiac surgery at Queen Sirikit National Institute of Child Health (QSNICH), Bangkok, from August 1st, 2002 to 2003. Demographic data, cardiac and related problems were obtained before operation. Anthropometry was performed at the presentation and post cardiac surgery. Nutritional status was assessed by Z-score of weight for age (ZWA), weight for height (ZWH) and height for age (ZHA). Malnutrition was defined as Z-score nutritional status of the patients before surgery was defined as normal 57%, malnutrition 40% and over-nutrition 3%. Malnutrition included underweight 28%, wasting 22% and stunting 16%. Post cardiac surgery, the means of ZWA, ZWH and ZHA were significantly increased and the prevalence of underweight and wasting were decreased to 17% and 6% respectively, with statistically significant from the baseline (p nutritional status.

    To assess the prevalence of nutritional disorders in children with inflammatory bowel disease (IBD) in Saudi Arabia. The data from a national cohort of children newly diagnosed with IBD between 2003 and 2012 were analyzed. The diagnosis of IBD and the differentiation between Crohn's disease (CD) and ulcerative colitis (UC) were confirmed by gastroenterologists according to the standard criteria. The body mass index (BMI) of each child [weight (kg)/height(2) (m)] was calculated at the time of diagnosis. The World Health Organization standards and references were used and the BMI for age > +1 and nutritional status between children underweight. Awareness of this finding is important for patient care.

    Persons living with human immunodeficiency virus (HIV) are living longer; therefore, they are more likely to suffer significant morbidity due to potentially treatable liver diseases. Clinical evidence suggests that the growing number of individuals living with HIV and liver disease may have a poorer health-related quality of life (HRQOL) than persons living with HIV who do not have comorbid liver disease. Thus, this study examined the multiple components of HRQOL by testing Wilson and Cleary's model in a sample of 532 individuals (305 persons with HIV and 227 persons living with HIV and liver disease) using structural equation modeling. The model components include biological/physiological factors (HIV viral load, CD4 counts), symptom status (Beck Depression Inventory II and the Medical Outcomes Study HIV Health Survey (MOS-HIV) mental function), functional status (missed appointments and MOS-HIV physical function), general health perceptions (perceived burden visual analogue scale and MOS-HIV health transition), and overall quality of life (QOL) (Satisfaction with Life Scale and MOS-HIV overall QOL). The Wilson and Cleary model was found to be useful in linking clinical indicators to patient-related outcomes. The findings provide the foundation for development and future testing of targeted biobehavioral nursing interventions to improve HRQOL in persons living with HIV and liver disease.

    Study Objective: Health-care workers (HCW) have an increased risk of acquiring infectious diseases and constitute a risk of transmission to their patients. Medical students working as HCW should therefore have the same immunity against vaccine preventable diseases as HCW. The aim of the study was to assess medical students' knowledge and attitudes towards occupationally indicated vaccinations as well as their vaccination status. Methods: Questionnaires were anonymously answered by medical students of the fourth preclinical semester at the Goethe-University Frankfurt. Results and Conclusion: Despite a high acceptance among medical students concerning vaccinations in general, the knowledge and vaccination status of the students should be improved. For instance, only 46.4% of the medical students knew that there is a general recommendation for HCW to receive the influenza vaccination and only 76.8% of the students stated to have received 2 measles vaccinations. Overall, 2/3 of the students were "very much in favour of vaccinations" or "completely in favour of vaccinations" and estimated the probability for unvaccinated HCW to acquire an occupationally associated infectious disease to be "quite high" or "very high". Having observed a positive attitude among medical students towards vaccinations, it should be possible to reach high vaccination coverage amongst students by offering them occupationally indicated vaccinations. Further knowledge concerning vaccine preventable diseases and the occupation-related increased risk for infectious diseases should be offered, as well. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Patients with lysosomal storage diseases (LSDs suffer from physical and mental disabilities, which together with poor access to professional care may lead to impaired oral health. This cross-sectional case-control study characterized the status of oral health in patients with LSDs in Poland. Thirty-six children and young adults with various forms of LSDs were examined. The data were compared with those from age- and sex-matched healthy controls. Exemplary cases were presented to highlight typical problems in oral care associated with LSDs. When possible, saliva was collected and analyzed for total protein, inflammatory mediators, and antioxidant status. Generally, patients with LSDs had significantly higher prevalence of caries, inferior gingival status, and inadequate oral hygiene. The severity of oral health impairment in mucopolysaccaridoses, the most common LSD in Poland, was similar to that seen in patients with mannosidoses or Pompe disease. Saliva could be collected only from few less handicapped patients. In MPS, it did not appear to differ significantly from the controls, but in patients with Pompe disease it contained lower concentrations of vascular endothelial growth factor (VEGF and monocyte chemoattractant protein-1 (MCP-1, but higher levels of tumor necrosis factor receptors 1 and 2 (TNF-R1, TNF-R2 and myeloperoxidase (MPO. In conclusion, Polish patients with LSDs have an inadequate level of oral hygiene and substantially deteriorated oral health.

    It is well established that nutritional status is an important factor affecting the outcome and recovery from disease or injury. Assessment of nutritional status is an integral part of care for patients with chronic kidney disease, especially for those treated with dialysis procedures. According to available literature, 18%-80% of patients on dialysis have some form of nutritional deficiency. Furthermore, in patients treated with dialysis procedures there is a rule called 'reverse epidemiology', according which patients with better nutritional status have better survival rate. Therefore, nutritional assessment should detect malnutrition and rate the overall nutritional status of each patient through clinical data categories: medical history, physical examination, nutrition physical examination, psychosocial history, demographics, physical activity, and current medical/surgical issues. Consequently, the main aim of our study was to analyze the nutritional status of our patients treated with hemodialysis procedures. Another aim was to analyze the applicability of measuring skinfold by caliper as a method of nutritional status assessment. During a six-month period, we analyzed 129 patients (57.4% of men and 42.6% of women), mean age 68.1 ± 12.4 years, treated with hemodialysis procedures (24.8% of patients were treated with online hemodiafiltration and 75.2% with standard, conventional hemodialysis) as the method of choice of renal replacement therapy (RRT) for more than 6 months. All patients were dialyzed three times a week for four hours on biocompatible synthetic membranes. The patients treated with online hemodiafiltration were dialyzed on high-flux helixone membranes, while those treated with standard, conventional hemodialysis were dialyzed on polysulfone membranes and helixone low-flux membranes. The mean time of RRT was 71.2 ± 56.7 months. During the study period, in each patient we followed medical history, and clinical and laboratory parameters of

    Full Text Available Abstract Background Social factors could offer useful information for planning prevention strategy for cardiovascular diseases. This analysis aims to explore the relationship between education, marital status and major cardiovascular risk factors and to evaluate the role of social status indicators in predicting cardiovascular events and deaths in several Italian cohorts. Methods The population is representative of Italy, where the incidence of the disease is low. Data from the Progetto CUORE, a prospective study of cohorts enrolled between 1983-1997, were used; 7520 men and 13127 women aged 35-69 years free of previous cardiovascular events and followed for an average of 11 years. Educational level and marital status were used as the main indicators of social status. Results About 70% of the studied population had a low or medium level of education (less than high school and more than 80% was married or cohabitating. There was an inverse relationship between educational level and major cardiovascular risk factors in both genders. Significantly higher major cardiovascular risk factors were detected in married or cohabitating women, with the exception of smoking. Cardiovascular risk score was lower in married or cohabitating men. No relationship between incidence of cardiac events and the two social status indicators was observed. Cardiovascular case-fatality was significantly higher in men who were not married and not cohabitating (HR 3.20, 95%CI: 2.21-4.64. The higher cardiovascular risk observed in those with a low level of education deserves careful attention even if during the follow-up it did not seem to determine an increase of cardiac events. Conclusions Preventive interventions on cardiovascular risk should be addressed mostly to people with less education. Cardiovascular risk score and case-fatality resulted higher in men living alone while cardiovascular factors were higher in women married or cohabitating. Such gender differences seem

    Full Text Available Background/Aims: One of the most common causes of anemia of chronic disease (ACD is chronic kidney disease. The main pathomechanism responsible for ACD is subclinical inflammation. The key element involved in iron metabolism is hepcidin, however, studies on new indices of iron status are in progress.The aim of the study was to assess the iron status in patients in early stages of chronic kidney disease, iron correlation with inflammation parameters and novel biomarkers of iron metabolism. Methods: The study included 69 patients. Standard laboratory measurements were used to measure the iron status, complete blood count, fibrinogen, prothrombin index, C-reactive protein concentration (CRP, creatinine, urea, uric acid. Commercially available kits were used to measure high-sensitivity CRP, interleukin 6 (IL-6, hepcidin-25, hemojuvelin, soluble transferrin receptor (sTfR, growth differentiation factor-15 (GDF-15 and zonulin. Results: Absolute iron deficiency was present in 17% of the patients, functional iron deficiency was present in 12% of the patients. Functional iron deficiency was associated with significantly higher serum levels of fibrinogen, ferritin, transferrin saturation, total iron binding capacity, hepcidin and older age relative to patients with absolute iron deficiency. In comparison with patients without iron deficiency, patients with functional iron deficiency were older, with lower prothrombin index, higher fibrinogen, CRP, hsCRP, sTfR, GDF-15, urea and lower eGFR. Hepcidin was predicted by markers of inflammation:ferritin, fibrinogen and IL-6. Conclusion: Inflammation is correlated with iron status. Novel biomarkers of iron metabolism might be useful to distinguish iron deficiency anemia connected with inflammation and absolute iron deficiency.

    Body composition assessment has the potential to improve the care of patients with chronic kidney disease (CKD). Whole-body multiple-frequency bioimpedance spectroscopy (BIS) appears to be a useful and appropriate technique for assessing hydration status and body composition in CKD patients. The aims of this study were to determine the hydration status by BIS in patients with advanced CKD, and to analyse the association of body fluid status with common clinical and biochemical characteristics. The prognostic value of the phase angle at 50 KHz (PA) was also evaluated. The study group consisted of 175 patients (66 ± 14 year, 77 females) with eGFR < 40 ml/min not yet on dialysis. Body composition was assessed by BIS (BCM, Fresenius). Hydration status was expressed as a percentage of the total body water (TBW). Patients were prospectively followed-up for a median of 481 days, and the main determinants of mortality were estimated by Cox regression analysis. The majority of patients (85%) showed a hydration status within ± 5% TBW. Patients with oedemas or uncontrolled arterial hypertension showed mean estimate fluid overload significantly higher than that of the other study patients. Fluid overload was negatively associated with serum albumin levels, body mass index and urinary sodium/potassium ratio; and positively with male gender and diabetes. During the follow-up period, 16 patients died (9%). The main determinants of mortality adjusted for other potential covariates were: Davies comorbidity index (HR = 4.304; P = .001), and PA (per each °; HR = 0.491; P = .026). BIS may help identify changes in hydration status in CKD patients not fully appreciated by clinical or biochemical assessment. PA was a significant predictor of mortality in these patients.

  19. A Bayesian Spatial Model to Predict Disease Status Using Imaging Data From Various Modalities

    2018-03-01

    Full Text Available Relating disease status to imaging data stands to increase the clinical significance of neuroimaging studies. Many neurological and psychiatric disorders involve complex, systems-level alterations that manifest in functional and structural properties of the brain and possibly other clinical and biologic measures. We propose a Bayesian hierarchical model to predict disease status, which is able to incorporate information from both functional and structural brain imaging scans. We consider a two-stage whole brain parcellation, partitioning the brain into 282 subregions, and our model accounts for correlations between voxels from different brain regions defined by the parcellations. Our approach models the imaging data and uses posterior predictive probabilities to perform prediction. The estimates of our model parameters are based on samples drawn from the joint posterior distribution using Markov Chain Monte Carlo (MCMC methods. We evaluate our method by examining the prediction accuracy rates based on leave-one-out cross validation, and we employ an importance sampling strategy to reduce the computation time. We conduct both whole-brain and voxel-level prediction and identify the brain regions that are highly associated with the disease based on the voxel-level prediction results. We apply our model to multimodal brain imaging data from a study of Parkinson's disease. We achieve extremely high accuracy, in general, and our model identifies key regions contributing to accurate prediction including caudate, putamen, and fusiform gyrus as well as several sensory system regions.

    To diagnosis and understand the pathophysiologic status of thyroid disease, not only hormonal measurements but also thyroid scan is believed to have a unique role. Especially in the cases of the change of the thyroid function by thyroiditis, it is emphasized that thyroid scan can be helpful in differential diagnosis, Discordant results of thyroid hormone levels and thyroid scan are found in transient hyperthyroidism, or in transient hypothyroidism. We analysed and reevaluated thyroid scan to look at the importance of thyroid scan. The results are summarised as follows: 1) 80%. of hyperthyroid patients had hyperthyroidism increased RAIU with even density, they are compatible with Graves' disease. 2) 2.1% of hyperthyroid patients had normal or decreased RAIU, which are classified as high iodine turn over genuine hyperthyroidism. 3) 8.5% of hyperthyroid patients had markedly decreased RAIU at both 2 hour and 24 hour, whose pathologic processes are suggested to be heterogenous namely subacute thyroiditis, postpartum thyroiditis, Hashimoto's thyroiditis, and pamless thyroiditis. 4) 45% of hypothyroid patients had increased 24 hr RAIU, 30% of hypothyroid patients were normal, 25%, decreased. In conclusion, thyroid scan should be reevaluated its useful role to asses the pathophysiologic status of thyroid disease. Especially in cases of transient thyrotoxicosis, thyroid scan is essential to diagnose and follow up the disease process.

    A system includes host and learning machines in electrical communication with sensors positioned with respect to an item of interest, e.g., a weld, and memory. The host executes instructions from memory to predict a binary quality status of the item. The learning machine receives signals from the sensor(s), identifies candidate features, and extracts features from the candidates that are more predictive of the binary quality status relative to other candidate features. The learning machine maps the extracted features to a dimensional space that includes most of the items from a passing binary class and excludes all or most of the items from a failing binary class. The host also compares the received signals for a subsequent item of interest to the dimensional space to thereby predict, in real time, the binary quality status of the subsequent item of interest.

    There is growing awareness of the coexistence of Alzheimer's disease and cerebrovascular disease (AD+CVD), however, due to lack of well-defined criteria and treatment guidelines AD+CVD may be underdiagnosed in Asia. Sixteen dementia specialists from nine Asia Pacific countries completed a survey in September 2014 and met in November 2014 to review the epidemiology, diagnosis and treatment of AD+CVD in Asia. A consensus was reached by discussion, with evidence provided by published studies when available. AD accounts for up to 60% and AD+CVD accounts for 10-20% of all dementia cases in Asia. The reasons for underdiagnosis of AD+CVD include lack of awareness as a result of a lack of diagnostic criteria, misdiagnosis as vascular dementia or AD, lack of diagnostic facilities, resource constraints and cost of investigations. There is variability in the tools used to diagnose AD+CVD in clinical practice. Diagnosis of AD+CVD should be performed in a stepwise manner of clinical evaluation followed by neuroimaging. Dementia patients should be assessed for cognition, behavioural and psychological symptoms, functional staging and instrumental activities of daily living. Neuroimaging should be performed using computed tomography or magnetic resonance imaging. The treatment goals are to stabilize or slow progression as well as to reduce behavioural and psychological symptoms, improve quality of life and reduce disease burden. First-line therapy is usually an acetylcholinesterase inhibitor such as donepezil. AD+CVD is likely to be under-recognised in Asia. Further research is needed to establish the true prevalence of this treatable and potentially preventable disease. © 2016 The Association for the Publication of the Journal of Internal Medicine.

    Malnutrition is one of the most important conditions that negatively affects the health of elder people, particularly in patients with dementia. To provide an assessment of nutritional status of patients affected by Alzheimer's disease (AD) living at home and of their caregivers by means of Mini Nutritional Assessment (MNA), and to explore the influence of different factors on nutrition. 90 patients affected by AD living at home and 90 age- and sex-matched caregivers were enrolled. Patients and caregivers, coming from an urban-rural fringe of Southern Italy, were assessed using full MNA, Mini-Mental State Examination, Geriatric Depression Scale- short form, Activity of Daily Living, and Instrumental Activities of Daily Living scales. Malnutrition was found with high prevalence in patients affected by AD of different severity (more than 95% of patients were malnourished or at risk of malnutrition), and associated with reduced functional status. An altered nutrition was also recognized with high rate in the group of caregivers (23.3% were malnourished and 41.1% at risk of malnutrition) and the worse nutritional condition was correlated with higher age and lower functional and cognitive status and education. A positive correlation between MNA score of AD patients and caregivers was found. Corrective measures should be taken in order to early identify nutritional deficiencies and risk of malnutrition observed with high rate in both groups of AD patients and their caregivers; in these subjects a nutrition education program and intervention policies are mandatory to restore nutritional status.

    Unique isolates of Vibrio parahaemolyticus (VPAHPND) have previously been identified as the causative agent of acute hepatopancreatic necrosis disease (AHPND) in shrimp. AHPND is characterized by massive sloughing of tubule epithelial cells of the hepatopancreas (HP), proposed to be induced by soluble toxins released from VPAHPND that colonize the shrimp stomach. Since these toxins (produced in broth culture) have been reported to cause AHPND pathology in reverse gavage bioassays with shrimp, we used ammonium sulfate precipitation to prepare protein fractions from broth cultures of VPAHPND isolates for screening by reverse gavage assays. The dialyzed 60% ammonium sulfate fraction caused high mortality within 24-48 hours post-administration, and histological analysis of the moribund shrimp showed typical massive sloughing of hepatopancreatic tubule epithelial cells characteristic of AHPND. Analysis of the active fraction by SDS-PAGE revealed two major bands at marker levels of approximately 16 kDa (ToxA) and 50 kDa (ToxB). Mass spectrometry analysis followed by MASCOT analysis revealed that both proteins had similarity to hypothetical proteins of V. parahaemolyticus M0605 (contig034 GenBank accession no. JALL01000066.1) and similarity to known binary insecticidal toxins called 'Photorhabdus insect related' proteins A and B (Pir-A and Pir-B), respectively, produced by the symbiotic, nematode bacterium Photorhabdus luminescens. In in vivo tests, it was shown that recombinant ToxA and ToxB were both required in a dose dependent manner to cause AHPND pathology, indicating further similarity to Pir-A and -B. A single-step PCR method was designed for detection of the ToxA gene and was validated using 104 bacterial isolates consisting of 51 VPAHPND isolates, 34 non-AHPND VP isolates and 19 other isolates of bacteria commonly found in shrimp ponds (including other species of Vibrio and Photobacterium). The results showed 100% specificity and sensitivity for detection of

    Full Text Available Abstract Background Volunteering participants in disease studies tend to be healthier than the general population partially due to specific enrollment criteria. Using modeling to accurately predict outcomes of cohort studies enrolling volunteers requires adjusting for the bias introduced in this way. Here we propose a new method to account for the effect of a specific form of healthy volunteer bias resulting from imposing disease status-related eligibility criteria, on disease-specific mortality, by explicitly modeling the length of the time interval between the moment when the subject becomes ineligible for the study, and the outcome. Methods Using survival time data from 1190 newly diagnosed lung cancer patients at MD Anderson Cancer Center, we model the time from clinical lung cancer diagnosis to death using an exponential distribution to approximate the length of this interval for a study where lung cancer death serves as the outcome. Incorporating this interval into our previously developed lung cancer risk model, we adjust for the effect of disease status-related eligibility criteria in predicting the number of lung cancer deaths in the control arm of CARET. The effect of the adjustment using the MD Anderson-derived approximation is compared to that based on SEER data. Results Using the adjustment developed in conjunction with our existing lung cancer model, we are able to accurately predict the number of lung cancer deaths observed in the control arm of CARET. Conclusions The resulting adjustment was accurate in predicting the lower rates of disease observed in the early years while still maintaining reasonable prediction ability in the later years of the trial. This method could be used to adjust for, or predict the duration and relative effect of any possible biases related to disease-specific eligibility criteria in modeling studies of volunteer-based cohorts.

    Full Text Available BACKGROUND: The inverse association between socioeconomic status and cardiovascular disease is well documented. We examined whether the impact of health counselling on cardiovascular risk factors in middle-aged men differed according to socioeconomic status. METHODS: We used data from a community based study assessing the risk for cardiovascular disease among middle-aged men in Helsinki, Finland. Traditional cardiovascular disease risk factors were measured and cardiovascular disease risk was assessed by a modified risk tool used in the North Karelia project (CVD Risk Score. Those men with increased risk for cardiovascular disease at their baseline visit in 2006 received lifestyle counselling. After two years these high-risk men were invited to a follow-up visit. The same measurements and risk assessments were repeated. RESULTS: Based on the CVD Risk Score there were significant differences between the groups at baseline (p = 0.001 and at follow-up (p<0.001 with the highest scores in the lowest educational group. There were no significant differences in traditional cardiovascular risk factors according to educational attainment between groups either at baseline or at follow-up. Baseline lifestyle characteristics differed between the groups regarding use of soft fat (p = 0.019. All groups responded positively to lifestyle counselling. CONCLUSIONS: The present study showed that lifestyle counselling is feasible in high-risk middle-aged men and lifestyle intervention works in all educational groups. Interestingly the traditional risk factors did not show improvement, but the risk score improved. From a practical point of view our findings stress the importance of using risk score calculators in health counselling instead of looking at individual cardiovascular disease risk factors.

    Objective: To evaluate changes in nutritional status of hospitalized patients with different diseases by subjective global assessment (SGA) and nutritional risk screening (NRS-2002). Methods: A prospective and parallel research done by multi-center collaboration from 34 hospitals in China from June to September 2014. Hospitalized patients with the following diseases were investigated: malignant tumor (2 487 cases), benign disease of the digestive system (1 358 cases), benign disease of the nervous system (1 043 cases), benign bone disease (451 cases), benign disease of the respiratory system(395 cases), cardiovascular disease (227 cases), benign thyroid and breast disease (179 cases), and endocrine disease (149 cases). Patients above the age of 18 and hospitalization time between 7-30 days were included. Physical indexes were measured, the NRS-2002 and SGA scores were recorded, the nutritional support were recorded during hospitalization and 24 hours after discharge from hospital. Measurement data between groups were analyzed using t test or Wilcoxon rank sum test, enumeration data and ranked data between groups were analyzed using chi-square test or Fisher exact test. Results: There were 6 638 cases of hospitalized patients, 3 861 cases were males and 2 777 were females, the male/female ratio was 1.4∶1.0; the median age was 60 years; the median height was 1.66 m; the median weight was 62 kg; the median body mass index (BMI)was 22.89 kg/m(2). At discharge, compared with that of admission, the body weight, BMI, grip strength, upper arm and calf circumferences of patients with malignant tumor were significantly decreased ( t =20.15-259.67, all P nutritional risk incidence rate (from NRS-2002) of patients with malignant tumor was significantly higher(χ(2)=21.275, P =0.000); moderate malnutrition (from SGA) incidence rate was significantly higher(χ(2)=62.318, P =0.000; χ(2)=11.312, P nutritional deficiency(except those with digestive benign diseases )received

    To investigate if the reduced cardiometabolic risk in Parkinson's disease (PD) is independent of nutritional status, body composition and fat distribution. We designed a case-control study comparing 80 non underweight PD patients with 80 controls matched for sex, age and body mass index (BMI). Nutritional assessment included: anthropometry (BMI and waist circumference [WC]), body composition estimated by impedance and biochemistry (fasting glucose, serum lipids and transaminases). The presence of arterial hypertension, diabetes mellitus and metabolic syndrome (MetS) were noted. Compared to controls and independently of gender, PD patients showed lower percentage of body fat (P nutritional status, body composition and fat distribution.

    Full Text Available Background To estimate Oral Hygiene (OH status in the Iranian population in 2011, and to determine the influence of socio-economic characteristics on OH, and its interrelation with common risk factors of Non-Communicable Diseases (NCDs. Methods Data including a total of 12,105 individuals aged 6-70 years were obtained from the sixth round of the surveys of NCDs risk factors in Iran. OH was recorded through a structured questionnaire measuring daily frequencies of tooth brushing and dental flossing. Descriptive analyses were performed on demographic characteristics in the complex sample survey setting. We also employed weighted binary logistic regression to compute Odds Ratio (OR as a measure of association between the response and explanatory factors. Furthermore, to construct an asset index, we utilized Principal Component Analysis (PCA. Results The percentage with minimum recommended daily OH practices was 3.7% among men and 7.7% among women (OR= 2.3; P< 0.001. Urban citizens were more likely to have their teeth cleaned compared to rural people (OR= 2.8; P< 0.001. For both genders, a relatively better condition was observed in the 25–34 age group (male: 5.6%; female: 10.3%. In addition, OH status improved significantly by increase in both level of education (P< 0.001 and economic status (P< 0.001. There were also apparent associations between self-care practices and specific behavioral risk factors, though the correlation with dietary habits and tobacco use could be largely explained by socio-economic factors. Conclusion OH situation in Iran calls for urgent need to assign proper interventions and strategies toward raising public awareness and reducing disparities in access to health facilities.

    Full Text Available In celiac disease (CD, for its multifactorial nature, the target organs are not limited to the gut, but include thyroid, liver, skin and reproductive and nervous systems. Between the extraintestinal symptoms associated with CD, autoimmune thyroid diseases (AITDs are more evident, underlining as CD-related autoimmune alterations can be modulated not only by gluten but also by various concurrent endogenous (genetic affinity, over-expression of cytokines and exogenous (environment, nutritional deficiency factors. In their pathogenesis a central role for over-expression of interleukin-15 (IL-15 is shown, by inhibiting apoptosis, leading to the perpetuation of inflammation and tissue destruction. Thyroid is particularly sensitive to selenium deficiency because selenoproteins are significant in biosynthesis and activity of thyroid hormones; besides, some selenoproteins as glutathione peroxidase are involved in inhibiting apoptosis. Thus, selenium malabsorption in CD can be thought as a key factor directly leading to thyroid and intestinal damage. Considering the complexity of this interaction and on the basis of available evidence, the aim of this review is to assess as preventive and therapeutic target the role of IL-15 and selenium in the pathogeneses of both CD and AITD.

    Full Text Available Objective: The objective of this study was to explore how Thai women of low socioeconomic status handle their type 2 diabetes. Methods: A qualitative interpretative method was used to study 19 women with type 2 diabetes in a suburban community in Thailand. Data were collected via semi-structured interviews and were analysed using inductive and constructive processes. Results: Participants’ lives underwent many changes between their initial diagnoses and later stages when they became adept at handling diabetes. Two themes emerged, which involved (1 the transition to handling diabetes and (2 the influences of the social environment. The first theme encompassed confronting the disease, reaching a turning point in the process of adaptation and developing expertise in handling diabetes. The second theme involved threats of loss of status and empowerment by families. These findings showed that becoming adept at handling diabetes required significant changes in women’s behaviours and required taking advantage of influences from the social environment. Conclusion: The process of developing expertise in handling diabetes was influenced by both inner and outer factors that required adjustment to learn to live with diabetes. Furthermore, the reductions found in women’s social statuses when they become patients in the healthcare system might pose a barrier to women of low socioeconomic status becoming adept at handling diabetes. However, the experiences of empowerment received from the women’s families acted as a powerful strategy to strengthen their handling of the disease. To develop accessible and sensitive health care for this population, it is important to pay attention to these findings.

    Objective: To assess the socioeconomic status, treatment being offered and the impact of congenital heart disease treatment on families. Study Design: Observational study. Place and Duration of Study: The Children's Hospital / Institute of Child Health, Lahore, from first March to 31 August 2010. Methodology: All patients undergoing a cardiac surgical or angiographic intervention were enrolled. Socioeconomic status was assessed by Kuppuswamy socioeconomic status scale with income group modification. The impact was measured by the source of financing, effect on family financing source and schooling and health of siblings. Results: Of 211 patients undergoing treatment in the study period, surgery was the definitive treatment in 164 (77.7%) and angiographic intervention in 47 (22.3%) patients. Male to female ratio was 1.5:1. The mean age of the patient was 39.1 +- 3.2 months (range 01 day to 15 years). Majority of families belonged to middle (66.4%, n=140) and lower (27%, n=57) socioeconomic class. The mean cost of medicines and disposable was PKR 78378.2 +- 8845.9 (US$ 933.1 +- 105.3) in open heart surgery, PKR 12581 +- 7010.8 (US$ 149.8 +- 83.5) in closed heart surgery and PKR 69091 + 60906 in angiographic interventions. In 63.1% patients, families contributed towards these costs either completely (12.3%) or partly (50.8%) with significant contribution from the hospital. Adverse effect on families ranged from leave without pay to losing jobs or business (46%), and selling their assets (11.3%). It also affected schooling and health of siblings (22.7% and 26.1% respectively). Conclusion: Majority of children with congenital heart disease belonged to middle and lower socioeconomic status in this study. Main definitive treatment was surgery. The cost of health care facilities posed a marked socioeconomic burden on those families. (author)

    Full Text Available Recent research on vitamin D in young children has expanded from bone development to exploring immunomodulatory effects. Our aim was to investigate the relationship of vitamin D status and allergic diseases in preschool-aged children in New Zealand. Dried capillary blood spots were collected from 1329 children during late-winter to early-spring for 25(OHD measurement by LC-MS/MS. Caregivers completed a questionnaire about their child’s recent medical history. Analysis was by multivariable logistic regression. Mean 25(OHD concentration was 52(SD19 nmol/L, with 7% of children <25 nmol/L and 49% <50 nmol/L. Children with 25(OHD concentrations ≥75 nmol/L (n = 29 had a two-fold increased risk for parent-report of doctor-diagnosed food allergy compared to children with 25(OHD 50–74.9 nmol/L (OR = 2.21, 1.33–3.68, p = 0.002. No associations were present between 25(OHD concentration and presence of parent-reported eczema, allergic rhinoconjunctivitis or atopic asthma. Vitamin D deficiency was not associated with several allergic diseases in these New Zealand preschool children. In contrast, high 25(OHD concentrations were associated with a two-fold increased risk of parental-report food allergy. This increase supports further research into the association between vitamin D status and allergic disease in preschool children.

    Despite vast availability of modern methods of treatment of chronic kidney disease and its complications, the short stature still is a major point of concern in adolescents with chronic kidney disease. The aim of the study was to assess changes in growth and nutritional status of Polish children on renal replacement therapy in the decade, 2004-2013. The study was designed as a cross-sectional analysis of anthropometric values and selected indices of growth status amongst children receiving dialysis in Poland between the years 2004 and 2013. Data were acquired during two different multicentre studies on hypertension in dialyzed children in Poland. Basic anthropometric parameters (body weight, body height/length, body mass index - BMI), dialysis adequacy and duration of RRT were assessed. The study showed that anthropometric parameters of children undergoing renal replacement therapy had not significantly changed in the last 10 years of observation. Children on RRT were still of short stature despite availability of modern methods of hormonal therapy and nutrition. Median of height z-score was -2.10 in 2004 and -2.19 in 2013. Expected clinical improvement in these measures was not proven. The cause of chronic kidney disease, method of dialysis, time on dialysis or dialysis adequacy did not influence the anthropometric parameters significantly in dialyzed children in Poland.

    Chronic obstructive pulmonary disease (COPD) is a leading cause of death and 70% of the cost of COPD is due to hospitalizations. Self-reported daily physical activity and health status have been reported as predictors of a hospitalization in COPD but are not routinely assessed. We tested the hypothesis that self-reported daily physical activity and health status assessed by a simple question were predictors of a hospitalization in a well-characterized cohort of patients with severe emphysema. Investigators gathered daily physical activity and health status data assessed by a simple question in 597 patients with severe emphysema and tested the association of those patient-reported outcomes to the occurrence of a hospitalization in the following year. Multiple logistic regression analyses were used to determine predictors of hospitalization during the first 12 months after randomization. The two variables tested in the hypothesis were significant predictors of a hospitalization after adjusting for all univariable significant predictors: >2 h of physical activity per week had a protective effect [odds ratio (OR) 0.60; 95% confidence interval (95% CI) 0.41-0.88] and self-reported health status as fair or poor had a deleterious effect (OR 1.57; 95% CI 1.10-2.23). In addition, two other variables became significant in the multivariate model: total lung capacity (every 10% increase) had a protective effect (OR 0.88; 95% CI 0.78-0.99) and self-reported anxiety had a deleterious effect (OR 1.75; 95% CI 1.13-2.70). Self-reported daily physical activity and health status are independently associated with COPD hospitalizations. Our findings, assessed by simple questions, suggest the value of patient-reported outcomes in developing risk assessment tools that are easy to use.

    To assess the stability of metabolic status and body mass index (BMI) status and their relative contribution to risk of diabetes, cardiovascular events, and mortality. A total of 14,685 participants from the Atherosclerosis Risk in Communities Study and 4,990 from the Coronary Artery Risk Development in Young Adults Study were included. People with healthy obesity (HO) are defined as those meeting all three indices of blood pressure, blood glucose, and blood lipids. People with unhealthy obesity crossed the risk threshold for all three criteria. In both healthy and unhealthy subgroups, risks for coronary heart disease (CHD), stroke, and mortality were comparable among BMI status during a mean 18.7-year follow-up. When compared with HO, hazard ratios were increased for diabetes (5.56, 95% confidence interval [CI] 4.12-7.48), CHD (5.60, 95% CI 3.14-9.98), stroke (4.84, 95% CI 2.13-10.97), and mortality (2.6, 95% CI 1.88-3.61) in people with unhealthy obesity. BMI only moderately increased the risks for diabetes among healthy subjects. In the Coronary Artery Risk Development in Young Adults Study over 20 years, 17.5% of lean subjects and 67.3% of overweight subjects at baseline developed obesity during follow-up. Despite rising BMI, metabolic status remained relatively stable. Metabolic status is relatively stable despite rising BMI. HO had lower risks for diabetes, CHD, stroke, and mortality than unhealthy subjects but increased diabetes risks than healthy lean people. Cardiometabolic risk factors confer much higher risk than obesity per se. © 2015 The Obesity Society.

    Chronic diseases are the leading causes of death in the United States. Chronic disease management occurs within all aspects of an individual's life, including the workplace. Though the social constructs of gender, race, class, and immigration status within the workplace have been considered, their connection to disease management among workers has been less explicitly explored. Using a sample of immigrant hotel housekeepers, we explored the connections between these four social constructs and hypertension management. This qualitative research study was guided by critical ethnography methodology. Twenty-seven hotel room cleaners and four housemen were recruited ( N = 31) and invited to discuss their experiences with hypertension and hypertension management within the context of their work environments. Being a woman worker within the hotel industry was perceived to negatively influence participants' experience with hypertension and hypertension management. In contrast, being a woman played a protective role outside the workplace. Being an immigrant played both a positive and a negative role in hypertension and its management. Being black and from a low socioeconomic class had only adverse influences on participants' experience with hypertension and its management. Being a woman, black, lower class, and an immigrant simultaneously contribute to immigrant hotel housekeepers' health and their ability to effectively manage their hypertension. The connection between these four constructs (gender, race, class, and immigration status) and disease management must be considered during care provision. Hotel employers and policy stakeholders need to consider those constructs and how they impact workers' well-being. More studies are needed to identify what mitigates the associations between the intersectionality of these constructs and immigrant workers' health and disease management within their work environment.

    To investigate the serological status of Old English Game (OEG) cockerels for a range of infectious diseases of poultry. Standard methods were used to screen serum collected from approximately 200 birds during routine dubbing operations, in 2004 and 2005. There was no serological evidence of infection with Newcastle disease, infectious bursal disease, or Salmonella Pullorum. Antibodies to infectious bronchitis virus, avian encephalomyelitis (AE) virus, Mycoplasma gallisepticum and Mycoplasma synoviae were detected. The disease status of OEG birds is similar to that of commercial poultry.

    Insect-borne diseases cause significant human morbidity and mortality. Current control and preventive methods against vector-borne diseases rely mainly on insecticides. The emergence of insecticide resistance in many disease vectors highlights the necessity to develop new strategies to control these insects. Vector transgenesis and paratransgenesis are novel strategies that aim at reducing insect vectorial capacity, or seek to eliminate transmission of pathogens such as Plasmodium sp., Trypanosoma sp., and Dengue virus currently being developed. Vector transgenesis relies on direct genetic manipulation of disease vectors making them incapable of functioning as vectors of a given pathogen. Paratransgenesis focuses on utilizing genetically modified insect symbionts to express molecules within the vector that are deleterious to pathogens they transmit. Despite the many successes achieved in developing such techniques in the last several years, many significant barriers remain and need to be overcome prior to any of these approaches become a reality. Here, we highlight the current status of these strategies, pointing out advantages and constraints, and also explore issues that need to be resolved before the establishment of transgenesis and paratransgenesis as tools to prevent vector-borne diseases.

    Vitamin C intake, and serum and leukocyte ascorbate levels were assessed serially over 6 months in 137 outpatients with Crohn's disease. Vitamin C intake was low in 18% of males and 37% of females. Serum ascorbate levels were suboptimal in 11% of males and 18% of females. Leukocyte ascorbate levels were low in 26% of males and 49% of females. Serum ascorbate levels were more frequently below the reference range in patients who smoked, but neither the serum nor the leukocyte ascorbate levels were affected by Crohn's disease activity, the use of an oral contraceptive agent, or by taking prednisone or sulfasalazine. Monthly diet counseling sessions significantly increased vitamin C intake, led to more patients consuming a normal ascorbate intake, and to a normalization of serum ascorbate values. We did not establish the importance of these ascorbate abnormalities on the clinical course of Crohn's disease. We conclude that low serum or leukocyte ascorbate levels are relatively common in patients with active or inactive Crohn's disease; these abnormalities are due in part to the reduced intake of dietary ascorbate; and the ascorbate status in patients with Crohn's disease may be normalized by improving the dietary intake of vitamin C.

    Measuring patient-centered outcomes is becoming increasingly important in patients with peripheral arterial disease (PAD), both as a means of determining the benefits of treatment and as an aid for disease management. In order to monitor health status in a reliable and sensitive way, the disease-specific measure Peripheral Artery Questionnaire (PAQ) was developed. However, to date, its correlation with traditional clinical indices is unknown. The primary aim of this study was to better establish the clinical validity of the PAQ by examining its association with functional indices related to PAD. Furthermore, we hypothesized that the clinical validity of this disease-specific measure is better as compared with the EuroQol-5-dimensional (EQ-5D), a standardized generic instrument. Data on 711 consecutive PAD patients undergoing surgery were collected from 11 Dutch hospitals in 2004. At 3-year follow-up, questionnaires including the PAQ, EQ-5D, and EuroQol-Visual Analogue Scale (EQ VAS) were completed in 84% of survivors. The PAQ was analyzed according to three domains, as established by a factor analyses in the Dutch population, and the summary score. Baseline clinical indices included the presence and severity of claudication intermittent (CI) and the Lee Cardiac Risk Index. All three PAQ domains (Physical Function, Perceived Disability, and Treatment Satisfaction) were significantly associated with CI symptoms (P values PAQ summary scores as compared with asymptomatic patients (58.6 +/- 27.8 vs 68.6 +/- 27.8, P = PAQ summary score and the subscale scores for Physical Functioning and Perceived Disability demonstrated a clear dose-response relation for walking distance and the Lee Risk Index (P values PAQ proved to be good as the PAQ subscales discriminated well between patients with or without symptomatic PAD and its severity as defined by walking distance. Furthermore, the PAQ subscales were directly proportional to the presence and number of risk factors relevant

    Beside its traditional role in skeletal health, vitamin D is believed to have multiple immunosuppressant properties, and low vitamin D status has been suggested to be a risk factor in the development of autoimmune disease. We investigated the association between vitamin D status and development...... of autoimmune disease. We included a total of 12,555 individuals from three population-based studies with measurements of vitamin D status (25-hydroxy vitamin D). We followed the participants by linkage to the Danish National Patient Register (median follow-up time 10.8 years). Relative risks of autoimmune...... disease were estimated by Cox regression and expressed as hazard ratios, HRs (95 % confidence intervals CIs). There were 525 cases of incident autoimmune disease. The risk for a 10 nmol/l higher vitamin D was: for any autoimmune disease (HR = 0.94 % CI 0.90, 0.98); thyrotoxicosis (HR = 0.83, 95 % CI 0...

    Full Text Available The paper presents the study of the relationship between the attitude to the disease, coping behavior of patients with coronary heart disease prior to coronary bypass grafting (CABG, and indicators of cognitive status. Bekhterev Institute Personality Questionnaire, Ways of Coping Behavior test by R. Lazarus, Mini-Mental State Examination scale, Frontal Dysfunction Battery test, and Clock- Drawing test were used in the study. The sample included 132 patients. The results of study show that in patients with coronary artery disease prior to CABG the most frequently observed type of attitude to the disease is either the harmonious type or a combination of harmonious and ergopathic types. Confrontation, Distancing, and Problem Solution Planning were identified as the preferred coping strategies. Correlation analysis revealed positive associations between cognitive status and harmonious, ergopathic, and hypochondriac types of attitude to the disease, and negative associations between cognitive status and anosognostic and sensitive types of attitude to the disease. Furthermore, positive correlations between cognitive status and Confrontation, Self-control, Responsibility taking, Problem Solution Planning, Positive revaluation coping strategies and negative correlations between cognitive status and Distancing and Escape-avoidance coping strategies were found. The results of this study will help to improve the level of diagnostic and rehabilitation psychological care of patients with coronary artery disease in preparation for CABG.

    To characterize pet ownership and pet health status in families of immunocompromised (IS) children, with emphasis in zoonotic diseases. Families of IS children from two hospitals in Santiago, Chile, were interviewed and their pets were evaluated by veterinary examination, coproparasitologic and skin dermatophytes test. In specific cases, other laboratory tests were performed in IS children or their relatives. 47 out of 70 contacted families had pets, 42 participated in the study. Several risk factors for IS children were observed, as having a turtle as a pet and to clean cat or turtle faeces. Lack of adequate veterinary control, immunizations and deparasitation of pets were observed. Some animals showed zoonotic diseases or agents, as Brucella canis, Cryptosporidium sp, Giardia intestinalis, Toxocara canis and scabies. 44% of dogs had ticks and 37% had fleas, both potential vectors of infections. Our results suggest that policies to provide safer pet contact in IS children are needed.

    The pathophysiology behind psychosis in patients with Alzheimer's disease (AD) remains unknown. Recently, vascular risk factors have been recognized as important modifiers of the clinical presentation of AD. The purpose of our study is to investigate the mechanism through which vascular risk factors mediate psychosis and whether or not it involves cerebrovascular lesions. Data was provided by the National Alzheimer's Coordinating Centre. The Uniform Data Set was used to collect information on subject-reported history of vascular risk factors, clinician-reported state of cognitive performance, and presence of psychosis based on the Neuropsychiatric Inventory Questionnaire (NPI-Q). The Neuropathology Data Set was used to evaluate the presence of vascular lesions and the severity of AD pathology. Subjects with high probability of AD based on the NIA/AA Reagan criteria were included in the analysis. We identified 1,459 patients with high probability of AD and corresponding NPI-Q scores. We confirmed the association between hypertension and diabetes on psychosis, specifically in delusions and the co-occurrence of delusions and hallucinations. Furthermore, the presence of white matter rarefaction based on pathological evaluation was associated with hallucinations. A history of vascular risk factors was positively associated with vascular lesions. However, vascular lesions in the presence of vascular risk factors did not increase the likelihood of psychosis. Furthermore, vascular lesions were not associated with greater cognitive or functional impairments in this group with severe AD pathology. Vascular risk factors and vascular lesions are independently associated with psychosis in patients with severe AD. However, vascular lesions are not the mechanism through which vascular risk factors mediate psychosis.

    Nutritional abnormalities and physical inactivity are highly prevalent in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to determine the association between nutritional status/body composition and physical performance in patients with COPD. A cross-sectional observational study was conducted in outpatients with clinically stable, moderate to very severe COPD. In the assessment of nutritional status, we used dual energy X-ray absorptiometry, anthropometry, serum biomarkers, and the Mini-Nutritional Assessment (MNA) questionnaire. Physical performance was measured by the 6-minute walk distance (6MWD), 4-metre gait speed (4MGS), and physical activity. Univariate and multivariate analyses were performed. In 111 patients (mean age 68 years, 69% men), the mean 6MWD was 376 ± 119 m, 4MGS 0.9 ± 0.2 m/s, and the average daily step count 8,059 ± 4,757. Patients with low exercise capacity (6MWD ≤ 350 m) had a significantly lower lean mass index (LMI) (p nutritional variables showed an independent association with low physical performance in the multivariate models. In conclusion, patients with low physical performance have deficient nutritional status, but we could not demonstrate an independent relationship between nutritional parameters and physical performance.

    A comprehensive approach to health highlights its close relationship with the social and economic conditions, physical environment and individual lifestyles. However, this relationship is not exempt from methodological problems that may bias the establishment of direct effects between the variables studied. Thus, further research is necessary to investigate the role of socioeconomic variables, their composition and distribution according to health status, particularly on non-communicable diseases. To shed light on this field, here a systematic review is performed using PubMed, the Cochrane Library and Web of Science. A 7-year retrospective horizon was considered until 21 July 2017. Twenty-six papers were obtained from the database search. Additionally, results from "hand searching" were also included, where a wider horizon was considered. Five of the 26 studies analyzed used aggregated data compared to 21 using individual data. Eleven considered income as a study variable, while 17 analyzed the effect of income inequality on health status (2 of the studies considered both the absolute level and distribution of income). The most used indicator of inequality in the literature was the Gini index. Although different types of analysis produce very different results concerning the role of health determinants, the general conclusion is that income distribution is related to health where it represents a measure of the differences in social class in the society. The effect of income inequality is to increase the gap between social classes or to widen differences in status.

    Reduced quality of life (QoL) is a known consequence of chronic disease in children, and this association may be more evident in those who are socio-economically disadvantaged. The aims of this systematic review were to assess the association between socio-economic disadvantage and QoL among children with chronic disease, and to identify the specific socio-economic factors that are most influential. MEDLINE, Embase and PsycINFO were searched to March 2015. Observational studies that reported the association between at least one measure of social disadvantage in caregivers and at least one QoL measure in children and young people (age 2-21 years) with a debilitating non-communicable childhood disease (asthma, chronic kidney disease, type 1 diabetes mellitus and epilepsy) were eligible. A total of 30 studies involving 6957 patients were included (asthma (six studies, n = 576), chronic kidney disease (four studies, n = 796), epilepsy (14 studies, n = 2121), type 1 diabetes mellitus (six studies, n = 3464)). A total of 22 (73%) studies reported a statistically significant association between at least one socio-economic determinant and QoL. Parental education, occupation, marital status, income and health insurance coverage were associated with reduced QoL in children with chronic disease. The quality of the included studies varied widely and there was a high risk of reporting bias. Children with chronic disease from lower socio-economic backgrounds experience reduced QoL compared with their wealthier counterparts. Initiatives to improve access to and usage of medical and psychological services by children and their families who are socio-economically disadvantaged may help to mitigate the disparities and improve outcomes in children with chronic illnesses. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    Full Text Available Abstract Background Children and adolescents with inflammatory bowel disease (IBD are at increased risk of vaccine preventable diseases (VPD. This includes invasive pneumococcal disease and influenza. The primary aim of this study was to describe compliance with current Australian guidelines for vaccination of children and adolescents diagnosed with IBD. A secondary aim was to review the serological screening for VPD. Methods A random sample of patients (0-18 years at diagnosis, were selected from the Victoria Australia state based Pediatric Inflammatory Bowel Disease Register. A multi-faceted retrospective review of immunization status was undertaken, with hospital records audited, a telephone interview survey conducted with consenting parents and the vaccination history was checked against the primary care physician and Australian Childhood Immunization Register (ACIR records. The routine primary childhood vaccinations and administration of the recommended additional influenza and pneumococcal vaccines was clarified. Results This 2007 audit reviewed the immunization status of 101individuals on the Victorian Pediatric IBD database. Median age at diagnosis was 12.1 years, 50% were on active immunosuppressive therapy. 90% (38/42 [95% confidence intervals (CI 77%; 97%] with complete immunization information were up-to-date with routine primary immunizations. Only 5% (5/101 [95% CI 2%; 11%] received a recommended pneumococcal vaccine booster and 10% (10/101 [95% CI 5%; 17%] had evidence of having ever received a seasonal influenza vaccine. Those living in rural Victoria (p = 0.005 and younger at the age of diagnosis (p = 0.002 were more likely to have ever received an influenza vaccine Serological testing, reviewing historical protection from VPD, identified 18% (17/94 with evidence of at least one serology sample. Conclusion This study highlights poor compliance in IBD patients for additional recommended vaccines. A multi-faceted approach is

    Infectious diseases and fish feeds management are probably the major expenses in the aquaculture business. Hence, it is a priority to define sustainable strategies which simultaneously avoid therapeutic procedures and reinforce fish immunity. Currently, one preferred approach is the use of immunostimulants which can be supplemented to the fish diets. Arginine is a versatile amino acid with important mechanisms closely related to the immune response. Aiming at finding out how arginine affects the innate immune status or improve disease resistance of European seabass (Dicentrarchus labrax) against vibriosis, fish were fed two arginine-supplemented diets (1% and 2% arginine supplementation). A third diet meeting arginine requirement level for seabass served as control diet. Following 15 or 29 days of feeding, fish were sampled for blood, spleen and gut to assess cell-mediated immune parameters and immune-related gene expression. At the same time, fish from each dietary group were challenged against Vibrio anguillarum and survival was monitored. Cell-mediated immune parameters such as the extracellular superoxide and nitric oxide decreased in fish fed arginine-supplemented diets. Interleukins and immune-cell marker transcripts were down-regulated by the highest supplementation level. Disease resistance data were in accordance with a generally depressed immune status, with increased susceptibility to vibriosis in fish fed arginine supplemented diets. Altogether, these results suggest a general inhibitory effect of arginine on the immune defences and disease resistance of European seabass. Still, further research will certainly clarify arginine immunomodulation pathways thereby allowing the validation of its potential as a prophylactic strategy.

    Full Text Available ABSTRACT Background Patients with liver disease often present protein-energy malnutrition. The assessment of food intake is very important in the investigation regarding the "health-disease" process. Objective To assess dietary intake of cirrhotic patients through food record during 3 days, correlating it with the nutritional status of the patient and the stage of the disease. Methods Cirrhotic outpatients from the Santa Casa de Misericórdia Hospital, RS, Brazil, were assessed. Nutritional assessment was performed by anthropometry; non-dominating handgrip strength; adductor pollicis muscle thickness; phase angle by bioelectrical impedance analysis; and Subjective Global Assessment. For analysis of food consumption we used the food records of 3 days using scales for weighing of all foods. Results We evaluated 25 (68% patients, in which there was a prevalence of cirrhosis by hepatitis C virus. The upper arm circumference, handgrip strength and phase angle by bioelectrical impedance analysis diagnosed 56% of malnourished. Phase angle by bioelectrical impedance analysis and upper arm circumference were associated with Child-Pugh score (P<0.05. The average consumption of calories, carbohydrates, proteins and lipids were within the recommended. However, sodium was above the recommendations, 106±57.2 mEq, and was inversely associated with Child-Pugh score (rs=-0.410; P=0.042. Conclusion Food intake did not have a significant difference between the Child-Pugh scores and nutritional status. In addition, food intake did not vary neither according to the stage of the disease, nor to the nutritional assessment, by the phase angle by bioelectrical impedance analysis.

    Full Text Available OBJECTIVE: To test the hypotheses that 1 coronary artery disease patients with lower aerobic fitness exhibit a lower ventilatory efficiency and 2 coronary artery disease patients with lower initial aerobic fitness exhibit greater improvements in ventilatory efficiency with aerobic exercise training. METHOD: A total of 123 patients (61.0±0.7 years with coronary artery disease were divided according to aerobic fitness status into 3 groups: group 1 (n = 34, peak VO217.5 and 24.5 ml/kg/min. All patients performed a cardiorespiratory exercise test on a treadmill. Ventilatory efficiency was determined by the lowest VE/VCO2 ratio observed. The exercise training program comprised moderate-intensity aerobic exercise performed 3 times per week for 3 months. Clinicaltrials.gov: NCT02106533 RESULTS: Before intervention, group 1 exhibited both lower peak VO2 and lower ventilatory efficiency compared with the other 2 groups (p<0.05. After the exercise training program, group 1 exhibited greater improvements in aerobic fitness and ventilatory efficiency compared with the 2 other groups (group 1: ▵ = -2.5±0.5 units; group 2: ▵ = -0.8±0.3 units; and group 3: ▵ = -1.4±0.6 units, respectively; p<0.05. CONCLUSIONS: Coronary artery disease patients with lower aerobic fitness status exhibited lower ventilatory efficiency during a graded exercise test. In addition, after 3 months of aerobic exercise training, only the patients with initially lower levels of aerobic fitness exhibited greater improvements in ventilatory efficiency.

    Visual hallucinations are frequent, disabling complications of advanced Parkinson’s disease, but their neuroanatomical basis is incompletely understood. Previous structural brain magnetic resonance imaging studies suggest volume loss in the mesial temporal lobe and limbic regions in subjects with Parkinson’s disease with visual hallucinations, relative to those without visual hallucinations. However, these studies have not always controlled for the presence of cognitive impairment or dementia, which are common co-morbidities of hallucinations in Parkinson’s disease and whose neuroanatomical substrates may involve mesial temporal lobe and limbic regions. Therefore, we used structural magnetic resonance imaging to examine grey matter atrophy patterns associated with visual hallucinations, comparing Parkinson’s disease hallucinators to Parkinson’s disease non-hallucinators of comparable cognitive function. We studied 50 subjects with Parkinson’s disease: 25 classified as current and chronic visual hallucinators and 25 as non-hallucinators, who were matched for cognitive status (demented or non-demented) and age (±3 years). Subjects underwent (i) clinical evaluations; and (ii) brain MRI scans analysed using whole-brain voxel-based morphometry techniques. Clinically, the Parkinson’s disease hallucinators did not differ in their cognitive classification or performance in any of the five assessed cognitive domains, compared with the non-hallucinators. The Parkinson’s disease groups also did not differ significantly in age, motor severity, medication use or duration of disease. On imaging analyses, the hallucinators, all of whom experienced visual hallucinations, exhibited grey matter atrophy with significant voxel-wise differences in the cuneus, lingual and fusiform gyri, middle occipital lobe, inferior parietal lobule, and also cingulate, paracentral, and precentral gyri, compared with the non-hallucinators.

    Full Text Available Abstract Background The infection rate of hepatitis B virus is continuously increasing in Pakistan. Therefore, a comprehensive study of epidemiological data is the need of time. Methods A total of 1300 individuals were screened for HBV infection markers including HBsAg, anti-HBsAg, HBeAg and anti-HBcAg. The association of these disease indicators was compared with patients' epidemiological characteristics like age, socio-economic status and residential area to analyze and find out the possible correlation among these variables and the patients disease status. Results 52 (4% individuals were found positive for HBsAg with mean age 23.5 ± 3.7 years. 9.30%, 33.47% and 12% individuals had HBeAg, antibodies for HBsAg, and antibodies for HBcAg respectively. HBsAg seropositivity rate was significantly associated (p = 0.03 with the residing locality indicating high infection in rural areas. Antibodies titer against HBsAg decreased with the increasing age reflecting an inverse correlation. Conclusion Our results indicate high prevalence rate of Hepatitis B virus infection and nationwide vaccination campaigns along with public awareness and educational programs are needed to be practiced urgently.

    Protein-energy wasting (PEW) is defined as a state of decreased body protein mass and fuel reserves (body protein and fat mass) and is a common complication of chronic kidney disease (CKD). It is multifactorial: the main causative factors are hormonal imbalances and a low nutrient intake, but low residual renal function, inadequate dialysis dose, chronic inflammation and metabolic acidosis are other important contributory factors. Adult PEW has been defined, but there is no accepted definition of pediatric PEW and consequently no precise diagnostic criteria. Assessing nutritional status in children is also complicated by the absence of a gold standard, specific abnormalities in body composition, and the slowly progressive course of the disease. The evaluation of PEW should take into account all of its pathogenetic aspects, which include dietary assessment, clinical and anthropometric assessment (based on weight, height, and body mass index), a panel of biochemical parameters, and a normalized protein catabolic rate (in the case of adolescents on hemodialysis). Bioimpedance indices can be used in individual patients on a regular basis in centers with expertise. The longitudinal follow-up data relating to the above parameters are valuable for comparing patient and normative data. Given the complex nature of PEW, only a multidisciplinary approach can provide an accurate assessment of nutritional status and its derangements in children with CKD and on dialysis.

Nutritional status has been shown to deteriorate with the progression of PD, due to motor and nonmotor complications. Dietary protein can reduce the effectiveness of levodopa treatment in PD patients, since the large neutral amino acids and levodopa share the same saturated carrier system, while fiber can improve the drug bioavailability. Moreover, nutrition seems to be directly involved in PD risk: high dietary intakes of animal fat, iron, mercury, and dairy, as well as western dietary patterns can increase it, while intake of some antioxidant compounds and plant-based dietary patterns can be protective. The means of ensuring good nutritional status in PD range from providing adequate energy and nutrients for the body, to considering in a broader perspective, the management of motor and nonmotor symptoms and chronic levodopa treatment complications, as well as pursuing potential neuroprotection. This review summarizes the most relevant results in the literature, and discusses the contribution of diet in the management of PD. Keywords: levodopa, Mediterranean diet, plant-based diet, protein-redistribution diet, vegetarian diet

    Full Text Available Malnutrition has been associated with increased morbidity and mortality. The objective of this study was to determine the nutritional status and micronutrient levels of hospitalized patients in an infectious disease clinic and investigate their association with adverse clinical outcomes. The nutritional status of the study participants was assessed using the Nutritional Risk Screening 2002 (NRS 2002 and micronutrient levels and routine biochemical parameters were tested within the first 24 h of the patient’s admission. The incidence of zinc, selenium, thiamine, vitamin B6, vitamin B12 deficiency were 66.7% (n = 40, 46.6% (n = 29, 39.7% (n = 27, 35.3% (n = 24, 14.1% (n = 9, respectively. Selenium levels were significantly higher in patients with urinary tract infections, but lower in soft tissue infections. Copper levels were significantly higher in patients with soft tissue infections. In the Cox regression models, lower albumin, higher serum lactate dehydrogenase levels and higher NRS-2002 scores were associated with increased death. Thiamine, selenium, zinc and vitamin B6 deficiencies but not chromium deficiencies are common in infectious disease clinics. New associations were found between micronutrient levels and infection type and their adverse clinical outcomes. Hypoalbuminemia and a high NRS-2002 score had the greatest accuracy in predicting death, systemic inflammatory response syndrome and sepsis on admission.

    Chronic obstructive pulmonary disease (COPD) is an important cause of morbidity and disability. Many studies have investigated factors influencing quality of life (QoL) in middle-aged COPD sufferers, but little attention has been given to elderly COPD. The aim of the present study was to investigate the impact of COPD on QoL and functional status in the elderly. Sixty COPD patients and 58 healthy controls over 65 years old were administered Pulmonary Function Tests, 6 min Walking Test (6MWD) for exercise tolerance, the Barthel Index and Mini Mental State Examination (MMSE) for functional status, the Geriatric Depression Scale (GDS) for mood, and the Saint George Respiratory Questionnaire (SGRQ) for QoL. FEV1 and PaO2 were reduced in COPD patients. Also the distance walked during 6MWD was significantly shorter for patients than controls (282.5 +/- 89.5 vs. 332.9 +/- 95.2 m; P < 0.01). Moreover, COPD patients had significantly worse outcomes for the Barthel Index, GDS and SGRQ. The logistic regression model demonstrated that a decrease in FEV1 is the factor most strictly related to the deterioration of QoL in COPD patients. Mood was also an independent factor influencing QoL. In conclusion, elderly COPD patients show a substantial impairment in QoL depending on the severity of airway obstruction; symptoms related to the disease may be exaggerated by mood deflection.

    Imbalance between antioxidant and oxidative stress is a major risk factor for pathogenesis of some chronic diseases such as chronic obstructive pulmonary disease (COPD). This study aimed to determine antioxidant and oxidative stress status, and also theirs association with respiratory function of male COPD patients to find the antioxidant predictors' factors. A total of 149 subjects were involved in a cross-sectional study. The study was conducted at two medical centers in Kuala Lumpur, Malaysia. Results of the study showed that plasma vitamin C was low in most of the subjects (86.6%). Total antioxidant capacity was the lowest in COPD stage IV compare to other stages (p < 0.05). Level of plasma vitamin A (p= 0.012) and vitamin C (p= 0.007) were low in malnourished subjects. The predictors for total antioxidant capacity were forced vital capacity (FVC) % predicted and intake of ?-carotene (R2= 0.104, p= 0.002). Number of cigarette (pack/ year) and smoking index (number/ year) were not associated with total antioxidant capacity of this COPD population. Plasma oxidative stress as assessed plasma lipid peroxidation (LPO) was only positively correlated with plasma glutathione (p= 0.002). It might be a need to evaluate antioxidant status especially in older COPD patients to treat antioxidant deficiency which is leading to prevent COPD progression.

    Increasing prevalence of non-communicable diseases (NCDs) has been observed in Ghana as in other developing countries. Past research focused on NCDs among adults. Recent researches, however, provide evidence on NCDs among children in many countries, including Ghana. Beliefs about the cause of NCDs among children may be determined by the socioeconomic status of parents and care givers. This paper examines the relationship between educational status of parents and/or care givers of children with NCDs on admission and their beliefs regarding NCDs among children. A total of 225 parents and/or care givers of children with NCDS hospitalized in seven hospitals in three regions (Greater Accra, Ashanti and Volta) were selected for the study. Statistical techniques, including the chi-square and multinomial logistic regression, were used for the data analysis. Educational status is a predictor of care giver's belief about whether enemies can cause NCDs among children or not. This is the only belief with which all the educational categories have significant relationship. Also, post-secondary/polytechnic (p-value =0.029) and university (p-value = 0.009) levels of education are both predictors of care givers being undecided about the belief that NCDs among children can be caused by enemies, when background characteristics are controlled for. Significant relationship is found between only some educational categories regarding the other types of beliefs and NCDs among children. For example, those with Middle/Juniour Secondary School (JSS)/Juniour High School (JHS) education are significantly undecided about the belief that the sin of parents can cause NCDs among children. Education is more of a predictor of the belief that enemies can cause NCDs among children than the other types of beliefs. Some categories of ethnicity, residential status and age have significant relationship with the beliefs when background characteristics of the parents and/or care givers were controlled

    Studies on the systemic availability of nutrients and nutritional status in Alzheimer's disease (AD) are widely available, but the majority included patients in a moderate stage of AD. This study compares the nutritional status between mild AD outpatients and healthy controls. A subgroup of Dutch drug-naïve patients with mild AD (Mini-Mental State Examination (MMSE) ≥20) from the Souvenir II randomized controlled study (NTR1975) and a group of Dutch healthy controls were included. Nutritional status was assessed by measuring levels of several nutrients, conducting the Mini Nutritional Assessment (MNA®) questionnaire and through anthropometric measures. In total, data of 93 healthy cognitively intact controls (MMSE 29.0 [23.0-30.0]) and 79 very mild AD patients (MMSE = 25.0 [20.0-30.0]) were included. Plasma selenium (p < 0.001) and uridine (p = 0.046) levels were significantly lower in AD patients, with a similar trend for plasma vitamin D (p = 0.094) levels. In addition, the fatty acid profile in erythrocyte membranes was different between groups for several fatty acids. Mean MNA screening score was significantly lower in AD patients (p = 0.008), but not indicative of malnutrition risk. No significant differences were observed for other micronutrient or anthropometric parameters. In non-malnourished patients with very mild AD, lower levels of some micronutrients, a different fatty acid profile in erythrocyte membranes and a slightly but significantly lower MNA screening score were observed. This suggests that subtle differences in nutrient status are present already in a very early stage of AD and in the absence of protein/energy malnutrition.

    To study the specific features of the nutritional status of patients with persistent chronic obstructive pulmonary disease (COPD) in relation to the hormone-regulating function of energy exchange in terms of leptin and to concurrently evaluate the functional status of fat and protein digestion and absorption and to measure body fat percentage. To assess the influence of these factors on the regulation of the serum concentration of leptin and its potential role in the development of trophological insufficiency in patients. In 93 patients with COPD (Stages I, II, and III in 22, 36, and 35 patients, respectively, the nutritional status was evaluated by somatometric methods. The concentration of leptin was measured by enzyme immunoassay using a test system (DSL, USA). Absorption was estimated by biochemical studies and by using radionuclides. Body fat content was determined, by measuring bioelectric impedance with an OmRon BF-302 apparatus (Japan). Protein and fat absorption was decreased in patients with moderate and mainly severe COPD as compared with that in the control group and correlated with body weight deficit and lower body fat percentage. Decreased leptin levels were detected in Stages II-III COPD and correlated with the degree of the disease and reduced protein (r = 0.68 +/- 0.02) and fat (r = 0.64 +/- 0.18) absorption. Protein and fat absorption impairments correlating with body weight deficit in patients with COPD underline the significant role of this mechanism in the development of trophological insufficiency. In COPD patients with trophological insufficiency, the lower circulating leptin levels that correlate with impaired absorption of fatty acids and protein characterize the pathogenetic role of secondary malabsorption syndrome in leptin-mediated impairments of energy exchange mechanisms. Functional insufficiency of the hormone-regulating mechanism responsible for energy exchange in terms of leptin in patients with Stages II-III COPD gives warning of

    To review the developments of recent decades and the current status of PET molecular imaging in Huntington's disease (HD). A systematic review of PET studies in HD was performed. The MEDLINE, Web of Science, Cochrane and Scopus databases were searched for articles in all languages published up to 19 August 2015 using the major medical subject heading ''Huntington Disease'' combined with text and key words ''Huntington Disease'', ''Neuroimaging'' and ''PET''. Only peer-reviewed, primary research studies in HD patients and premanifest HD carriers, and studies in which clinical features were described in association with PET neuroimaging results, were included in this review. Reviews, case reports and nonhuman studies were excluded. A total of 54 PET studies were identified and analysed in this review. Brain metabolism ([ 18 F]FDG and [ 15 O]H 2 O), presynaptic ([ 18 F]fluorodopa, [ 11 C]β-CIT and [ 11 C]DTBZ) and postsynaptic ([ 11 C]SCH22390, [ 11 C]FLB457 and [ 11 C]raclopride) dopaminergic function, phosphodiesterases ([ 18 F]JNJ42259152, [ 18 F]MNI-659 and [ 11 C]IMA107), and adenosine ([ 18 F]CPFPX), cannabinoid ([ 18 F]MK-9470), opioid ([ 11 C]diprenorphine) and GABA ([ 11 C]flumazenil) receptors were evaluated as potential biomarkers for monitoring disease progression and for assessing the development and efficacy of novel disease-modifying drugs in premanifest HD carriers and HD patients. PET studies evaluating brain restoration and neuroprotection were also identified and described in detail. Brain metabolism, postsynaptic dopaminergic function and phosphodiesterase 10A levels were proven to be powerful in assessing disease progression. However, no single technique may be currently considered an optimal biomarker and an integrative multimodal imaging approach combining different techniques should be developed for monitoring potential neuroprotective and preventive treatment

    To study the psycho-emotional status and prevalence of the coronary heart disease (CHD) and the idiopathic hypertensia (IH) at patients with the peptic ulcer of a stomach (PUS) and at patients with a peptic ulcer of a duodenum is (YaB DPK). Examination of 226 patients with an exacerbation of a peptic ulcer was conducted. Patients were distributed in 3 groups of observation depending on localization of ulcerative process. At all surveyed questioning was carried out, data on heriditary burdeness, smoking, alcohol intake, existence of somatopathies were specified, clinic-morphological implications of a peptic ulcer were studied. Feeling of alarm was present at 109 (48.2%) patients with a peptic ulcer, from them at 92 (40.7%) the subclinical level of alarm is noted, and at 17 (7.5%) clinically expressed form is taped. At 39.3% of the examined patients the depression is defined, from them two thirds of patients had the subclinical level of a depression, and 13 people suffered from clinically expressed depression form. Communication of recurrence with a stress was noted at 86.0% of patients, professionally caused stress--at 44.4%. In our research at the time of the beginning of a disease prevalence of an ischemic heart disease among patients with an ulcer of a duodenum (DPK) made 18.2%. In group of patients with the combined localization of ulcerative defect in a stomach and in DPK which already had an ischemic heart disease before emergence of the second ulcerative defect there were 26.6% that statistically significantly doesn't differ. However that by the time of emergence of the combined lesion this category of patients made already 73.4% is indicative. In case of DPK ulcer prevalence of an ischemic heart disease increased from the moment of the beginning of a disease until carrying out research twice (to 36.4%), but patients with the combined ultserozny lesion nevertheless distinguished both larger initial prevalence of an ischemic heart disease, and more expressed

    The threat of non-communicable diseases ("NCDs") is increasingly becoming a global health crisis and are pervasive in high, middle, and low-income populations resulting in an estimated 36 million deaths per year. There is a need to assess intellectual property rights ("IPRs") that may impede generic production and availability and affordability to essential NCD medicines. Using the data sources listed below, the study design systematically eliminated NCD drugs that had no patent/exclusivity provisions on API, dosage, or administration route. The first step identified essential medicines that treat certain high disease burden NCDs. A second step examined the patent and exclusivity status of active ingredient, dosage and listed route of administration using exclusion criteria outlined in this study. We examined the patent and exclusivity status of medicines listed in the World Health Organization's ("WHO") Model List of Essential Drugs (Medicines) ("MLEM") and other WHO sources for drugs treating certain NCDs. i.e., cardiovascular and respiratory disease, cancers, and diabetes. We utilized the USA Food and Drug Administration Orange Book and the USA Patent and Trademark Office databases as references given the predominant number of medicines registered in the USA. Of the 359 MLEM medicines identified, 22% (79/359) address targeted NCDs. Of these 79, only eight required in-depth patent or exclusivity assessment. Upon further review, no NCD MLEM medicines had study patent or exclusivity protection for reviewed criteria. We find that ensuring availability and affordability of potential generic formulations of NCD MLEM medicines appears to be more complex than the presence of IPRs with API, dosage, or administration patent or exclusivity protection. Hence, more sophisticated analysis of NCD barriers to generic availability and affordability should be conducted in order to ensure equitable access to global populations for these essential medicines.

    When data representing a preferred measurement of risk cannot be obtained, as is often the case for global animal diseases, decisions that affect millions of people and their animals are typically made based on expert opinion. Expert opinion can be and has been used to address the critical lack of data existing for prevalence and incidence of many global diseases, including foot-and-mouth disease (FMD). However, when a conclusion based on expert opinion applies to a topic as sensitive as FMD, which has tremendous economic, political, and social implications, care should be taken to understand the accuracy of and differences in the opinion data. The differences in experts' opinions and the relative accuracy of an expert opinion elicitation for "diagnosing" country-level FMD presence were examined for the years 1997-2003 using Bayesian methods. A formal survey of eight international FMD experts revealed that individual experts had different opinions as to the probability of finding FMD in a country. However, a weighted average of the experts' responses was relatively accurate (91% sensitivity and 85% specificity) at identifying the FMD status of a country, compared to using a method that employed information available from World Organization for Animal Health (OIE). The most apparent disagreements between individual experts and available information were found for Indonesia, South Korea, and South America, and, in general, the experts seemed to believe that countries in South Asia were more likely to be positive than other countries that reported FMD cases to OIE. This study highlights new methodology that offers a standardized, quantitative, and systematic means by which expert opinion can be used and assessed.

    Full Text Available Creutzfeldt-Jakob disease (CJD, the most common form of human prion diseases, is a fatal condition with a mortality rate reaching 85% within one year of clinical presentation. CJD is characterized by rapidly progressive neurological deterioration in combination with typical electroencephalography (EEG and magnetic resonance imaging (MRI findings and positive cerebrospinal spinal fluid (CSF analysis for 14-3-3 proteins. Unfortunately, CJD can have atypical clinical and radiological presentation in approximately 10% of cases, thus making the diagnosis often challenging. We report a rare clinical presentation of sporadic CJD (sCJD with combination of both expressive aphasia and nonconvulsive status epilepticus. This patient presented with slurred speech, confusion, myoclonus, headaches, and vertigo and succumbed to his disease within ten weeks of initial onset of his symptoms. He had a normal initial diagnostic workup, but subsequent workup initiated due to persistent clinical deterioration revealed CJD with typical MRI, EEG, and CSF findings. Other causes of rapidly progressive dementia and encephalopathy were ruled out. Though a rare condition, we recommend consideration of CJD on patients with expressive aphasia, progressive unexplained neurocognitive decline, and refractory epileptiform activity seen on EEG. Frequent reimaging (MRI, video EEGs and CSF examination might help diagnose this fatal condition earlier.

    To determine whether disabled diabetic persons have a higher prevalence of risk factors for heart disease and stroke than do diabetic persons without disability. RESEARCH, DESIGN, AND METHODS: Data were analyzed for noninstitutionalized adults in 27 states and the District of Columbia that participated in the Behavioral Risk Factor Surveillance System (BRFSS) in 2001 and/or 2003. Logistic regression analysis was used to estimate the adjusted prevalence and odds ratios of disabled diabetic persons, by sociodemographic characteristics. The logit form of each model was used to estimate conditional marginal probabilities of risk factors for heart disease and stroke among diabetic persons, by disability status. Diabetic persons with disability were more likely than those without disability to have more risk factors for heart disease and stroke, including insufficient leisure-time physical activity or inactivity (adjusted prevalence: 75.2% vs. 63.3%; Pvs. 43.3%; Pvs. 48.4%; P=.038), and hypertension (63.9% vs. 56.6%; Ptwo or more, three or more, and four or more risk factors (97.2% vs. 95.6%, 83.5% vs. 74.0%, 56.5% vs. 41.1%, and 22.2% vs. 13.6%, respectively; Pstroke. Health care guidelines specifically targeting diabetic patients with disability may be needed to aid health care providers in addressing these risk factors.

    Objective We assessed the protective effect of medical male circumcision (MMC) against HIV, herpes simplex virus type 2 (HSV-2), and genital ulcer disease (GUD) incidence. Design Two thousand, seven hundred and eighty-seven men aged 18–24 years living in Kisumu, Kenya were randomly assigned to circumcision (n=1391) or delayed circumcision (n =1393) and assessed by HIV and HSV-2 testing and medical examinations during follow-ups at 1, 3, 6, 12, 18, and 24 months. Methods Cox regression estimated the risk ratio of each outcome (incident HIV, GUD, HSV-2) for circumcision status and multivariable models estimated HIV risk associated with HSV-2, GUD, and circumcision status as time-varying covariates. Results HIV incidence was 1.42 per 100 person-years. Circumcision was 62% protective against HIV [risk ratio =0.38; 95% confidence interval (CI) 0.22–0.67] and did not change when controlling for HSV-2 and GUD (risk ratio =0.39; 95% CI 0.23–0.69). GUD incidence was halved among circumcised men (risk ratio =0.52; 95% CI 0.37–0.73). HSV-2 incidence did not differ by circumcision status (risk ratio =0.94; 95% CI 0.70–1.25). In the multivariable model, HIV seroconversions were tripled (risk ratio =3.44; 95% CI 1.52–7.80) among men with incident HSV-2 and seven times greater (risk ratio =6.98; 95% CI 3.50–13.9) for men with GUD. Conclusion Contrary to findings from the South African and Ugandan trials, the protective effect of MMC against HIV was independent of GUD and HSV-2, and MMC had no effect on HSV-2 incidence. Determining the causes of GUD is necessary to reduce associated HIV risk and to understand how circumcision confers protection against GUD and HIV PMID:22382150

Selenium has been implicated in the aetiology of asthma, and associations between low selenium status and asthma in New Zealand children have been reported. The aim was to investigate the association between selenium status and allergic disease in a birth cohort of New Zealand children. The New Zealand Asthma and Allergy Cohort Study is a prospective birth cohort in Wellington and Christchurch, involving 1105 infants born 1997-2001. During the 6-year assessment (n = 635), associations were investigated between plasma selenium (PlSe) and whole blood glutathione peroxidase activity (WBGPx) and allergy-related health outcomes including asthma, wheeze, hayfever, rhinitis, eczema and rash. Wellington children had greater PlSe and WBGPx than Christchurch children (P location, current household smoking (5-6 years), maternal smoking during pregnancy, family history (either parent with asthma, eczema or hayfever), prioritized ethnicity (Maori, Pacific peoples, Other, European), gender, season born, number of siblings, New Zealand Deprivation Index and body mass index at 6 years. Analysis of PlSe or WBGPx as continuous variables or of quartiles of PlSe with health outcomes showed no significant associations after adjustment. Univariate analysis of quartiles of PlSe and WBGPx with persistent wheeze showed significant inverse trends (P = 0.005 for both), but these reduced after adjustment. Our results do not support a strong association between selenium status and the high incidence of asthma in New Zealand. However, there was a modest association between lower PlSe and WBGPx activity and higher incidence of persistent wheeze. © 2012 Blackwell Publishing Ltd.

    To determine the prevalence of malnutrition and its relation to various factors in community-dwelling elderly with newly diagnosed Alzheimer's disease (AD). Retrospective cross-sectional study. Memory clinic in a rural part of the Netherlands. 312 Community-dwelling AD patients, aged 65 years or older, were included. At the time the diagnosis AD was made, socio-demographic characteristics and data on nutritional status (Mini Nutritional Assessment (MNA)), cognitive function (Mini Mental State Examination (MMSE), Cambridge Cognitive Examination (Camcog)), functional status (Interview for Deterioration in Daily Living Activities in Dementia (IDDD), Barthel Index (BI)) and behaviour (Revised Memory and Behaviour Problems Checklist (RMBPC)) were assessed. Characteristics of well-nourished patients (MNA score >23.5) were compared to characteristics of patients at risk of malnutrition (MNA score 17-23.5). Linear regression analysis was performed to assess the effect of various factors on nutritional status. The prevalence of malnutrition was 0% and 14.1% was at risk of malnutrition. AD patients at risk of malnutrition were more impaired in basic and complex daily functioning than well-nourished AD patients (median IDDD score 41.5 [25th -75th percentile 38.8-48.0] versus median IDDD score 40.0 [25th -75th percentile 37.0-43.0], p = 0.028). The degree of impairment in basic and complex daily functioning (IDDD) was independently related to nutritional status (MNA) (p = 0.001, B = -0.062). One in seven community-dwelling elderly with newly diagnosed AD is at risk of malnutrition. The degree of impairment in daily functioning is independently related to nutritional status. Therefore, assessment of the nutritional status should be included in the comprehensive assessment of AD patients. The relation between daily functioning, nutritional status and AD warrants further investigation.

    The etiology of weight loss in Alzheimer's disease (AD) patients is still uncertain. This study was designed to investigate the possible factors that might contribute to weight change of AD patients. From July 1999 to June 2001, we recruited 51 AD patients and 27 non-demented controls. Demographic data, neuropsychological tests, Geriatric Depression Scale-Short Form, eating behavior questionnaire, dietary and physical activity diaries, anthropometric and laboratory measures of nutritional status were assessed. More than half of our AD patients developed body weight loss, and overall, the AD patients were significantly thinner than the non-demented subjects. Anthropometric and laboratory measures suggested a poorer nutritional status in the AD patients. The AD patients had fewer daily physical activities. More AD patients had the problem of poor appetite. However, daily calorie intake was not significantly different between the two groups. The AD patients, especially those who presented with body weight loss, even consumed more calories per body weight kilogram (kg) per day. In the food composition analysis, AD patients took more carbohydrate than controls. Multivariate regression analysis showed the existence of AD and poor appetite were the main risk factors of weight loss. We suggest that the pathophysiological process in AD gives rise to the changes of appetite and metabolic state in AD patients, and that these changes contribute to the weight loss.

    It is now well accepted that theory of mind (ToM) functioning is impaired in Parkinson's disease (PD) patients. However, what remain unknown are the functions that underlie this impairment. It has been suggested that cognitive skills may be key in this area of functioning; however, many of the cognitive tests used to assess this have relied on intact visuospatial abilities. This study aimed to examine whether deficits in ToM were generated by cognitive or visuospatial dysfunction and the mediating effect of visuospatial function on ToM performance. Fifty PD patients (31 male, 19 female; mean age = 66.34 years) and 49 healthy controls (16 male, 33 female; mean age = 67.29 years) completed a ToM task (reading the mind in the eyes) and visuospatial task (line orientation). The results revealed that current cognitive status was a significant predictor for performance on the ToM task, and that 54% of the total effect of cognitive status on ToM was mediated by visuospatial abilities. It was concluded that visuospatial functioning plays an important mediating role for the relationship between executive dysfunction and affective ToM deficits in PD patients, and that visuospatial deficits may directly contribute to the presence of affective ToM difficulties seen in individuals with PD.

    This study reviews empirical findings on two debated issues related to the phenomenon of impulse control disorders (ICD) in patients with Parkinson's disease (PD) treated with dopamine agonists: the role of "premorbid" or "baseline" personality traits and the role of cognitive status. A review of both these issues may help clinicians to understand why only some PD patients, when treated with dopamine agonists, develop an ICD: besides the treatment, which other neuropsychiatric characteristics represent a risk factor to develop an ICD? A literature review was performed on studies of ICD in PD patients, in electronic databases ISI Web of Knowledge, Medline and PsychInfo, conducted in January 2011. In the general population, impulsivity, depression and difficulties with executive functions, especially of inhibitory control, are factors associated with ICD development. As regards cognitive functions, PD patients present executive difficulties, and patients with ICD present more difficulties in comparison to patients without ICD. As regards personality characteristics, PD patients present a trait of negative affect, which could predispose them to affective disorders and could represent an affective risk factor for the development of ICD; as regards impulsivity, preliminary findings support the hypothesis that premorbid "baseline" levels may moderate the decrease of impulsivity because of the progressive dopaminergic deficit in PD patients and therefore also moderate the development of ICD. Longitudinal psychometric and cognitive studies, following PD patients since the clinical diagnosis and during dopaminergic treatment, are needed to confirm the role of personality traits and cognitive status on ICD development in this clinical population.

    Full Text Available Abstract Background The population in Norway has become multi-ethnic due to migration from Asia and Africa over the recent decades. The aim of the present study was to explore differences in the self-reported prevalence of cardiovascular disease (CVD and associated risk factors by diabetes status in five ethnic minority groups compared to ethnic Norwegians. Methods Pooled data from three population-based cross-sectional studies conducted in Oslo between 2000 and 2002 was used. Of 54,473 invited individuals 24,749 (45.4% participated. The participants self-reported health status, underwent a clinical examination and blood samples were drawn. A total of 17,854 individuals aged 30 to 61 years born in Norway, Sri-Lanka, Pakistan, Iran, Vietnam or Turkey were included in the study. Chi-square tests, one-way ANOVAs, ANCOVAs, multiple and logistic regression were used. Results Age- and gender-standardized prevalence of self-reported CVD varied between 5.8% and 8.2% for the ethnic minority groups, compared to 2.9% among ethnic Norwegians (p Conclusions Ethnic differences in the prevalence of CVD were prominent for individuals without diabetes. Primary CVD prevention including identification of undiagnosed diabetes should be prioritized for ethnic minorities without known diabetes.

    Full Text Available Bioimpedance analysis is a noninvasive, low cost and a commonly used approach for body composition measurements and assessment of clinical condition. There are a variety of methods applied for interpretation of measured bioimpedance data and a wide range of utilizations of bioimpedance in body composition estimation and evaluation of clinical status. This paper reviews the main concepts of bioimpedance measurement techniques including the frequency based, the allocation based, bioimpedance vector analysis and the real time bioimpedance analysis systems. Commonly used prediction equations for body composition assessment and influence of anthropometric measurements, gender, ethnic groups, postures, measurements protocols and electrode artifacts in estimated values are also discussed. In addition, this paper also contributes to the deliberations of bioimpedance analysis assessment of abnormal loss in lean body mass and unbalanced shift in body fluids and to the summary of diagnostic usage in different kinds of conditions such as cardiac, pulmonary, renal, and neural and infection diseases.

    Weight loss and malnutrition are frequent and serious complications of Alzheimer's disease. The aim of the present article was to describe the cognitive and behavioural characteristics of the test population within the frame of the PHRC REAL.FR cohort (for Réseau sur la Maladie d'Alzheimer Français), depending on their nutritional state, and to consider their evolution one year after the original inclusion. The study population' stratification was done in three groups according to their Mini Nutritional Assessment (MNA) score: malnutrition group (MNA nutritional status group (MNA > or = 23.5). 561 patients were evaluated at inclusion time, 393 at one year. The evaluation included the following scales: Mini Nutritional Assessment (MNA), Mini Mental State Examination (MMSE), Activities Daily Living (ADL), Instrumental Activities Daily Living (IADL), Neuro Psychiatric Inventory (NPI) and Zarit scale (ZARIT). Comparison and descriptive analysis for each MNA group at baseline and at one year has been performed. at baseline, the well-nourished and the malnutrition risk groups are significantly different concerning age, IADL and NPI; the well-nourished and undernutrition groups are different concerning MMSE, NPI and Zarit; the malnutrition risk and undernutrition groups are only different concerning NPI. At one year, the well-nourished and the malnutrition risk and undernutrition groups are different concerning one lonely variable, the NPI, in a significant way. The comparison of the three groups between baseline and one-year evaluation demonstrate for the well-nourished group an aggravation of MMSE, ADL, IADL, NPI, for the malnutrition risk group of MMSE and IADL, and for the undernutrition group of MMSE, IADL and NPI. Among the patients suffering from Alzheimer's disease, the most malnutritioned worsen highly on cognitive and functional capacities. Furthermore, the nutritional aggravation seems strongly linked to behavioural disorders aggravation. The improvement of

    In West Africa, the prevalence of sickle cell disease (SCD) is 2%. The disease adversely affects growth, development and organ function including the kidneys. There is however a dearth of information about the renal status of SCD children in Ghana. To assess the renal status of children with SCD in steady state. A cross-sectional case-control study. Paediatric Sickle Cell Clinic, Korle Bu Teaching Hospital, Accra. Cases-357 SCD cases and 70 of their HbAA siblings as controls. Documentation of their socio-demographic data, clinical data and dipstick urinalysis findings, and renal ultrasonography on selected participants. The mean [SD] age was 7.18 [3.15]yrs for cases and 5.16[3.28]yrs for controls. The genotypes were Hb SS (76.7%), Hb SC (21.8 %), and Hb Sβthal (1.4%). Urinalysis showed leucocyturia in 12.6% versus 5.7% (χ2=62.5 and the p=0.000)), isolated proteinuria in 2.8% versus 1.43% (χ2=10.01 and p=0.001) haematuria in 2.6% versus 0% (χ2=9.233, p=0.002) and nitrites in 2.2% versus 1.4% (χ2=16.3,p=0.02) of cases and controls respectively. The youngest SCD case with proteinuria was 2 yrs. old. Proteinuria prevalence increased with age, , occurring in 5.7% of cases aged 9-11yrs. and 20.6% of cases aged 12 yrs. Two-thirds of the proteinuria cases were aged 9-12 yrs., of whom 50% were aged 12 yrs. Renal ultrasound findings were normal in all those examined. Urinary abnormalities suggesting nephropathy occur early in SCD patients in Ghana. Routine dipstick screening at clinic visits countrywide would help early detection and prompt intervention to limit renal impairment.

    Factors related with hyperhomocysteinemia (HHcy) and the impact of HHcy in Parkinson's disease (PD) are not well understood. We investigated the factors associated with increased levels of homocysteine (Hcy) and the relationship between HHcy and motor symptoms, cognitive status, and vascular risk in patients with Parkinson's disease. Among 60 patients (29 males, 48.3%) with PD, the stage of the disease, the severity of clinical symptoms, and the patients' cognitive status were measured using a modified Hoehn and Yahr Staging Scale (mHY), Unified Parkinson's Disease Rating Scale (UPDRS) II and III, and Mini-Mental State Examination (MMSE), respectively. Patients were also noted for having dyskinesia and hallucinations. Serum vitamin B12, folic acid, and plasma Hcy levels were measured. Furthermore, the presence of vascular risk factors was recorded. Finally, we investigated carotid artery intima-media thickening and stenosis using colour Doppler ultrasonography as well as the presence of ischemic lesions using brain imaging techniques. Plasma Hcy levels were higher with advanced age and in males. In addition, there was an inverse relationship between Hcy and vitamin B12 levels. There was no correlation between HHcy and the stage of the disease, severity of motor symptoms, cognitive status as assessed by the MMSE, vascular risk factors, carotid artery atherosclerotic findings, and ischemic brain lesions. Plasma Hcy levels may rise due to several factors in PD. However, the resulting HHcy has no significant effect on the clinical picture in terms of motor features, cognitive status, and vascular diseases.

    Studies of close binary stars are being persued more vigorously than ever, with about 3000 research papers and notes pertaining to the field being published during the triennium 1976-1978. Many major advances and spectacular discoveries were made, mostly due to increased observational efficiency and precision, especially in the X-ray, radio, and ultraviolet domains. Progress reports are presented in the following areas: observational techniques, methods of analyzing light curves, observational data, physical data, structure and models of close binaries, statistical investigations, and origin and evolution of close binaries. Reports from the Coordinates Programs Committee, the Committee for Extra-Terrestrial Observations and the Working Group on RS CVn binaries are included. (Auth./C.F.)

    There are pronounced socioeconomic disparities in coronary heart disease, but the extent to which these primarily reflect gradients in underlying coronary artery disease severity or in the clinical manifestation of advanced disease is uncertain. We measured the relationship between socioeconomic status (SES) as indexed by grade of employment and coronary artery calcification (CAC) in the Whitehall II epidemiological cohort, and tested the contribution of lifestyle, biological and psychosocial factors in accounting for this association. CAC was assessed in 528 asymptomatic men and women aged 53-76 years, stratified into higher, intermediate and lower by grade of employment groups. Lifestyle (smoking, body mass index, alcohol consumption, physical activity), biological (blood pressure, lipids, fasting glucose, inflammatory markers) and psychosocial factors (work stress, financial strain, social support, depression, hostility, optimism) were also measured. Detectable CAC was present in 293 participants (55.5%). The presence of calcification was related to lifestyle and biological risk factors, but not to grade of employment. But among individuals with detectable calcification, the severity of CAC was inversely associated with grade of employment (p = 0.010), and this relationship remained after controlling for demographic, lifestyle, biological and psychosocial factors. Compared with the higher grade group, there was a mean increase in log Agatston scores of 0.783 (95% C.I. 0.265-1.302, p = 0.003) in the intermediate and 0.941 (C.I. 0.226-1.657, p = 0.010) in the lower grade of employment groups, after adjustment for demographic, lifestyle, biological and psychosocial factors. Low grade of employment did not predict the presence of calcification in this cohort, but was related to the severity of CAC. These findings suggest that lower SES may be particularly relevant at advanced stages of subclinical coronary artery disease, when calcification has developed.

    Coronary heart disease is a narrowing of coronary artery due to plaque build-up. [1] Chronic periodontitis increases risk of cardiovascular disease. P.gingivalis is linked to both diseases. Objective: to analyse quantitative difference of P.gingivalis on dental plaque and its relationship with periodontal status of CHD patient and control. Methods: Periodontal status of 66 CHD patient and 40 control was checked. Subgingival plaque was isolated and P.gingivalis was measured using real-time PCR. Result: P.gingivalis of CHD patient differs from control. P.gingivalis is linked to pocket depth of CHD patient. Conclusion: P.gingivalis count of CHD patient is higher than control. P.gingivalis count is not linked to any periodontal status, except for pocket depth of CHD patient.

  19. Evolution of cataclysmic binaries

    Paczynski, B.

    1981-01-01

    Cataclysmic binaries with short orbital periods have low mass secondary components. Their nuclear time scale is too long to be of evolutionary significance. Angular momentum loss from the binary drives the mass transfer between the two components. As long as the characteristic time scale is compared with the Kelvin-Helmholtz time scale of the mass losing secondary the star remains close to the main sequence, and the binary period decreases with time. If angular momentum loss is due to gravitational radiation then the mass transfer time scale becomes comparable to the Kelvin-Helmoltz time scale when the secondary's mass decreases to 0.12 Msub(sun), and the binary period is reduced to 80 minutes. Later, the mass losing secondary departs from the main sequence and gradually becomes degenerate. Now the orbital period increases with time. The observed lower limit to the orbital periods of hydrogen rich cataclysmic binaries implies that gravitational radiation is the main driving force for the evolution of those systems. It is shown that binaries emerging from a common envelope phase of evolution are well detached. They have to lose additional angular momentum to become semidetached cataclysmic variables. (author)

    To review the developments of recent decades and the current status of PET molecular imaging in Huntington's disease (HD). A systematic review of PET studies in HD was performed. The MEDLINE, Web of Science, Cochrane and Scopus databases were searched for articles in all languages published up to 19 August 2015 using the major medical subject heading ''Huntington Disease'' combined with text and key words ''Huntington Disease'', ''Neuroimaging'' and ''PET''. Only peer-reviewed, primary research studies in HD patients and premanifest HD carriers, and studies in which clinical features were described in association with PET neuroimaging results, were included in this review. Reviews, case reports and nonhuman studies were excluded. A total of 54 PET studies were identified and analysed in this review. Brain metabolism ([{sup 18}F]FDG and [{sup 15}O]H{sub 2}O), presynaptic ([{sup 18}F]fluorodopa, [{sup 11}C]β-CIT and [{sup 11}C]DTBZ) and postsynaptic ([{sup 11}C]SCH22390, [{sup 11}C]FLB457 and [{sup 11}C]raclopride) dopaminergic function, phosphodiesterases ([{sup 18}F]JNJ42259152, [{sup 18}F]MNI-659 and [{sup 11}C]IMA107), and adenosine ([{sup 18}F]CPFPX), cannabinoid ([{sup 18}F]MK-9470), opioid ([{sup 11}C]diprenorphine) and GABA ([{sup 11}C]flumazenil) receptors were evaluated as potential biomarkers for monitoring disease progression and for assessing the development and efficacy of novel disease-modifying drugs in premanifest HD carriers and HD patients. PET studies evaluating brain restoration and neuroprotection were also identified and described in detail. Brain metabolism, postsynaptic dopaminergic function and phosphodiesterase 10A levels were proven to be powerful in assessing disease progression. However, no single technique may be currently considered an optimal biomarker and an integrative multimodal imaging approach combining different techniques should be developed

    To explore the relationship between socioeconomic status and the risk factors of cardiovascular diseases in retirees from a community in Shanghai. Observational study involved 9 943 retirees aged 50 and over in Shanghai. Both single factor and multi-factor analyses methods were used to describe the correlation between factors as:educational level, marital status, annual household income and risk of hypertension, coronary heart disease, stroke etc. A new defined compound index was used to assess the relevance of socioeconomic status on the risk of cardiovascular diseases, based on logistic regression model. After adjusted for age, the risk of cardiovascular diseases in these retirees was influenced by socioeconomic status. In general, opponent correlations in education levels and prevalence of hypertension were found between female and male. Compared with those having received college or higher education, the risk of hypertension increased in females when the education level declined, with OR as 1.08 (95% CI:0.89-1.30). For those having had senior high school junior high school or elementary education, the risks of hypertension were 1.26 (95%CI:1.05-1.51), 1.34 (95%CI:1.08-1.65), 0.72 (95%CI:0.59-0.87),0.78 (95%CI:0.64-0.94), and 0.70 (95%CI:0.52-0.92) for males, respectively. The risk of cardiovascular diseases increased with annual household income. Compared with high level of socioeconomic status, lower socioeconomic status might decline the risk of cardiovascular diseases in males by approximately 30%, with OR for medium being 0.72 (95%CI:0.61-0.84) and for lower ones it was 0.70 (95% CI:0.57-0.87). However, similar correlations were not found in females. No significant relationship was found between marital status and the prevalence of cardiovascular diseases in this study. The risks of cardiovascular diseases varied with different socioeconomic status, indicating that tailored interventions should be conducted in different socioeconomic groups.

    Thallium-201 myocardial scintigraphy (TMS) is the most important, accurate and noninvasive diagnostic tool for the detection of regional myocardial perfusion. This agent is a potassium analog and the biologic half life in normal myocardium is 4 hours. Therefore, serial imaging after a single dose of Tl-201 at the peak of the exercise makes differential diagnosis possible between stress induced ischemia (transient perfusion defect with redistribution) and myocardial fibrosis or scar (permanent defect). The reproducibility is around 90%. The overall sensitivity in 4,094 patients reviewed from the literature was 83% with a specificity of 87%. The accuracy of TMS for the diagnosis of ischemic heart disease was 85%. Sensitivity increases in the order of visual (83%), computer analysis of standard scintigraphy (91%), and computer analysis of pinhole tomography (96%), but there is no significant difference in specificity among them. Also, sensitivity increases in the order of single (73%), double (83%) and triple (90%) vessel d isease. However, TMS does not indicate the correct number of vessels involved. In this paper, we discuss the current status of use and limitations of TMS in the diagnosis of ischemic heart disease. (author)

    Full Text Available Worldwide malaria remains a major public health problem. The situation is worst in South East Asian Region & Sub-Saharan Africa. In India more than 90% of people live in malaria endemic areas. Apart from increased morbidity & mortality malaria affects the socio-economic status of a country. Odisha, a State with only 4 % of India’s population records maximum disease burden. In last decade a changed epidemiology is being observed and malaria has spread from rural and tribal areas to urban and newer territories due to urbanization, industrialization and developmental projects. Many decades have passed after launch of National Malaria Control Program but the rate of decrease in malaria caseload seems unsatisfactory. The various challenges involved in malaria control are under-reporting, increased drug and insecticide resistance, inaccessible areas and poor health infrastructure in high burden areas. Various newer interventions have been included in malaria control program such as Insecticide treated bed net; Artesunate-based combination therapy for P falciparum cases, bivalent Rapid diagnostic test etc. In addition to robust surveillance and appropriate treatment, a strong political commitment, community awareness and more funding is required to reduce disease burden.

    Background Coronary artery disease (CAD) is a leading cause of mortality, morbidity, and disability in the world. The high prevalence and morbidity associated with CAD in Iran is one of the most pressing health problems. Methods We have reviewed the status of CAD and prevalence of its traditional and novel risk factors based on the published papers in recent years that may have an impact on the rate of CAD in Iran. Evaluation of current impact of metabolic syndrome in Iran was the other aim of this review, as it contributes to pathogenesis of coronary artery disease. We reviewed all PubMed indexed related studies. Some evidences from national articles which were published by the Ministry Of Health and Medical Education Research Council Certified Medical Journals of Islamic Republic of Iran were also included. Results The prevalence of CAD, coronary risk factors and metabolic syndrome in Iran is higher than Western countries and similar to some Middle East countries. There are limited data with regard to novel coronary risk factors in Iran. Conclusion Primary and secondary prevention of CAD including life style modifications and dietary interventions strongly recommended in Iranian population. PMID:24069531

    Clinicopathologic correlation studies are critically important for the field of Alzheimer disease (AD) research. Studies on human subjects with autopsy confirmation entail numerous potential biases that affect both their general applicability and the validity of the correlations. Many sources of data variability can weaken the apparent correlation between cognitive status and AD neuropathologic changes. Indeed, most persons in advanced old age have significant non-AD brain lesions that may alter cognition independently of AD. Worldwide research efforts have evaluated thousands of human subjects to assess the causes of cognitive impairment in the elderly, and these studies have been interpreted in different ways. We review the literature focusing on the correlation of AD neuropathologic changes (i.e. β-amyloid plaques and neurofibrillary tangles) with cognitive impairment. We discuss the various patterns of brain changes that have been observed in elderly individuals to provide a perspective for understanding AD clinicopathologic correlation and conclude that evidence from many independent research centers strongly supports the existence of a specific disease, as defined by the presence of Aβ plaques and neurofibrillary tangles. Although Aβ plaques may play a key role in AD pathogenesis, the severity of cognitive impairment correlates best with the burden of neocortical neurofibrillary tangles. PMID:22487856

    In chronic kidney disease (CKD) a deficiency of 1,25-dihydroxyvitamin D is common. The aim of this review was to compare vitamin D status after oral supplementation of vitamin D3 to that of serial suberythemal irradiation in end-stage kidney disease (ESKD) patients. Ninety-five patients, with a mean age of 62 (range=35-82) years, were treated with a mean dose of 35,000 (20,000-60,000) IU vitamin D3 per week for a period of 18 months. Fourteen patients, with a mean age of 51 (range=41-57) years, were whole-body UVB irradiated for over 6 months. From 3 hemodialysis patients skin biopsies were performed. With oral supplementation 25(OH)D3 increased by 60%. With UV irradiation 25(OH)D3 increased by 400%. Gene expression analysis demonstrated an improvement in the vitamin D receptor (VDR) by 0.65 fold, in 1-alpha-hydroxylase (CYP27B1) by 1.0 fold, and in 25-hydroxylase (CYP2R) by 1.2 fold. Serial suberythemal UVB irradiation of patients with CKD on dialysis is capable to improve serum 25(OH)D3 and 1,25(OH)2D3 by enhancing the skin's ability to activate vitamin D.

    We evaluated the periodontal health status and oral health behavior among hospitalized patients with chronic obstructive pulmonary disease (COPD) to assess the association of COPD with dental health. A group of 100 hospitalized patients with COPD and a group of 100 age, sex, and race-matched control patients were included in this study. Detailed case histories along with standardized measures of oral health including gingival index, plaque index (PI), and simplified oral hygiene index (OHI) were estimated and compared. Probing depths and clinical attachment levels (CALs) were recorded at four sites per tooth. C-reactive protein (CRP) levels in saliva and serum were also measured. The study subjects had similar demographics and distribution in either group. Patients with COPD had significantly lower brushing frequency, poor periodontal health (OHI and PI), greater gingival inflammation, and deeper pockets/CALs compared to controls. Further COPD patients had significantly higher serum and salivary CRP levels compared to control groups. Lower brushing frequency, poor oral health, and presence of destructive periodontal disease were observed among patients with COPD, which warrants promoting dental care and oral health knowledge as an integrated approach to treating COPD patients.

    Full Text Available Abstract Background Inflammatory Bowel Disease (IBD, which includes both Crohn’s disease (CD and ulcerative colitis (UC, is caused by a complex interplay involving genetic predisposition, environmental factors and an infectious agent. Mycobacterium avium subsp. paratuberculosis (MAP is a promising pathogen candidate since it produces a chronic intestinal inflammatory disease in ruminants that resembles CD in humans. MAP is a ubiquitous microorganism, although its presence in the food chain, especially in milk from infected animals, is what made us think that there could be an association between lactase persistence (LP and IBD. The LCT mutation has brought adaptation to dairy farming which in turn would have increased exposure of the population to infection by MAP. NOD2 gene mutations are highly associated to CD. Methods In our study, CD and UC patients and controls from the North of Spain were genotyped for the lactase gene (LCT and for three NOD-2 variants, R702W, G908R and Cins1007fs. MAP PCR was carried out in order to assess MAP infection status and these results were correlated with LCT and NOD2 genotypes. Results As for LP, no association was found with IBD, although UC patients were less likely to present the T/T−13910 variant compared to controls, showing a higher C-allele frequency and a tendency to lactase non-persistence (LNP. NOD2 mutations were associated to CD being the per-allele risk higher for the Cins1007fs variant. MAP infection was more extended among the healthy controls (45.2% compared to CD patients (21.38% and UC patients (19.04% and this was attributed to therapy. The Asturian CD cohort presented higher levels of MAP prevalence (38.6% compared to the Basque CD cohort (15.5%, differences also attributed to therapy. No interaction was found between MAP infection and LCT or NOD2 status. Conclusions We conclude that LP is not significantly associated with IBD, but that MAP infection and NOD2 do show not mutually

    The fact that chronic diseases are leading causes of mortality and morbidity in hospitals in Vietnam was certified by yearly statistical information. However, population-based knowledge of chronic diseases is still largely lacking. This article examines the prevalence of major chronic diseases and their relationships with sociodemographic status and selected lifestyle risk factors among the adult population in a rural community in the north of Vietnam. A representative sample comprising 2500 adults aged 25-74 years was surveyed in 2005 using a structured questionnaire. Both descriptive and analytical statistical analyses were applied. Thirty-nine per cent of the respondents had at least one of the studied chronic diseases. The prevalence of current smoking was 59% among men and 0.7% among women. The prevalence of at-risk alcohol drinking was 67% among men and 3% among women. Increasing age, low education and doing other jobs (small traders, temporary workers, housekeepers, handicraft makers and jobless), as well as tobacco use and at-risk alcohol drinking, were found to be associated with a higher probability of having at least one chronic disease of interest. Economic status was found to be inversely correlated with the probability of having at least one chronic disease among women only. The findings from this study indicated that chronic conditions and lifestyle risk factors were very common among the adult population in rural Vietnam. There is an association between chronic diseases and lower socioeconomic status and unhealthy lifestyle risk factors.

    Full Text Available Chaetocnema pulicaria and C. denticulata are recognized as vectors of Stewart wilt disease caused by Pantoea stewartii on maize. These insects have not been reported yet in Indonesia, but Stewart wilt disease has been reported in Java and Sumatera Islands. Genus Chaetocnema which presented in Indonesia is C.basalis. It is not cleared whether C. basalis is a vector for Stewart wilt disease like C. pulicaria and C. denticulata. This reseach was aimed to conduct the confirmation on status whether C. basalis have a role as vector of Stewart wilt disease on maize or not. C. basalis imago were collected from maize growing areas in Yogyakarta, and then starved for 24 h. Treatments were applied by placing imago of C. basalis on infected-P. stewartii plants for 72 h. Five insects were then transferred to each plot of healthy plant (1 plot consisted of 5 plants for 72 h. For control, imago of C. basalis were put on healthy plants for 72 h and five insects were then transferred to other healthy plant (1 plot consisted of 5 plants for 72 h. Each treatment was repeated three times. On the fifteenth days after transmission, PCR assays were carried out on leaf samples and isolates of bacteria. All sampled leaves analysis showed that there were no Stewart wilt diseases transmission based on PCR assay and bacterial isolates. This concluded that C. basalis is not a vector for  Stewart wilt disease on maize.   Intisari Chaetocnema pulicaria dan C. denticulata merupakan serangga vektor penyakit layu stewart yang disebabkan oleh bakteri Pantoea stewartii pada tanaman jagung.

    Full Text Available Children with recurrent respiratory diseases according to various authors comprise from 20% to 90% of children’s population of the Russian Federation. In such children neurotic reactions can develop easier, they get tired quicker, study worse, all that in turn provokes formation of pedagogical problems and deterioration of psychological climate in a family.The purpose of this research was detection of medico-social features of health status and quality of life in children with recurrent respiratory diseases for scientifically based development of improving and correctional actions. Under our supervision there were 195 children aged from 5 to 12 years with various levels of health.Methods of research included a complex assessment of level of health, functional, laboratory and biochemical techniques, assessment of quality of life with a questionnaire PedsQL™4.0. As a result of the conducted research ball scaling was carried out and groups of high and moderate risk for decline in quality of life of children with recurrent respiratory diseases were allocated. The comprehensive correctional and improving program for children from group of «high risk» for decline in quality of life and level of health was developed. After intervention more than 16% of examined children began to attend sports sections (physical functioning improved, and because of reduction of absence from schools, their role, emotional and social functioning improved (children became more attentive at lessons, progress increased. The received results allow to confirm efficiency of the developed program in comparison with temporary industry standards of rendering medical care to children.

    Full Text Available Background. Atherosclerosis is a chronic inflammatory disease and the acute clinical manifestations represent acute on chronic inflammation. Neutrophil gelatinase-associated lipocalin (NGAL is found in the granules of human neutrophils, with many diverse functions. The aim of this study was to evaluate the hypothesis that levels NGAL in blood may reflect the inflammatory process in various stages of coronary artery disease. Methods. We studied 140 patients, with SA 40, UA 35, NSTEMI 40, and STEMI 25, and 20 healthy controls. Serum NGAL was measured upon admission and before coronary angiography. Results. Significant differences were observed in median serum-NGAL(ng/mL between patients with SA (79.23 (IQR, 37.50–100.32, when compared with UA (108.00 (68.34–177.59, NSTEMI (166.49 (109.24–247.20, and STEMI (178.63 (111.18–305.92 patients and controls (50.31 (44.30–69.78 with significant incremental value from SA to STEMI. We observed a positive and significant correlation between serum-NGAL and hs-CRP (spearman coefficient rho = 0.685, <0.0001 as well as with neutrophil counts (r = 0.511, <0.0001. Conclusions. In patients with coronary artery disease serum levels of NGAL increase and reflect the degree of inflammatory process. In patients with acute coronary syndromes, serum levels of NGAL have high negative predictive value and reflecting the inflammatory status could show the severity of coronary clinical syndrome.

    Full Text Available BackgroundWhile the evidence supporting a positive association between diabetes mellitus and kidney stone disease (KSD is solid, studies examining the association between impaired fasting glucose (IFG and KSD show inconsistent results. Currently, there are no studies examining the relationship between impaired glucose tolerance (IGT and KSD. The objective of this study is to investigate the effects of different glycemic statuses on KSD. The results may help to motivate patients with diabetes to conform to treatment regimens.MethodsWe conducted a cross sectional study of a population that underwent health check-ups between January 2000 and August 2009 at the Health Evaluation Center of National Cheng Kung University Hospital. A total of 14,186 subjects were enrolled. The following categories of glycemic status were used according to the criteria of the 2009 American Diabetes Association: normal glucose tolerance, isolated IGT, isolated IFG, combined IFG/IGT, and diabetes. The existence of KSD was evaluated using renal ultrasonography, and the presence of any hyperechoic structures causing acoustic shadowing was considered to be indicative of KSD.ResultsThe prevalence of KSD was 7.4% (712/9,621, 9.3% (163/1,755, 10.8% (78/719, 12.0% (66/548, and 11.3% (174/1,543 in subjects with NGT, isolated IGT, isolated IFG, combined IFG/IGT, and diabetes, respectively. Isolated IFG, combined IFG/IGT, and diabetes were associated with KSD after adjusting for other clinical variables, but isolated IGT was not. Age (41 to 64 years vs. ≤40 years, ≥65 years vs. ≤40 years, male gender, hypertension, and hyperuricemia were also independently associated with KSD.ConclusionIsolated IFG, combined IFG/IGT, and diabetes, but not isolated IGT, were associated with a higher risk of KSD.

    Dyslipidemia, hypertension, and diabetes are well-established risk factors for cardiovascular disease (CVD). This study investigated the prevalence and management status of these factors for dyslipidemia among Korean adults aged 30 years old and older. The prevalence and management status of dyslipidemia, hypertension, and diabetes were analyzed among 12229 subjects (≥30 years) participating in the Korea National Health and Nutrition Survey 2010-2012. Dyslipidemia was defined according to treatment criteria rather than diagnostic criteria in Korea. Therefore, hyper-low-density lipoprotein (LDL) cholesterolemia was defined if LDL cholesterol levels exceeded the appropriate risk-based threshold established by the National Cholesterol Education Program Adult Treatment Panel III. The age-standardized prevalence was highest for dyslipidemia (39.6%), followed by hypertension (32.8%) and diabetes (9.8%). The lowest patient awareness was found for dyslipidemia (27.9%). The treatment rate was 66.5% for diabetes and 57.3% for hypertension, but only 15.7% for dyslipidemia. The control rate among those undergoing treatment was highest for hypertension (64.2%), followed by dyslipidemia (59.2%) and diabetes (22.1%). The higher the risk levels of CVD were, the lower the control rate of dyslipidemia. While the prevalence of dyslipidemia was higher than hypertension and diabetes, awareness and treatment rates thereof were lower. Higher CVD-risk categories showed lower control rates of dyslipidemia. In order to improve awareness and control rates of dyslipidemia, diagnostic criteria should be reconciled with treatment targets based on cardiovascular risk in Korean populations.

    Full Text Available OBJETIVO: Descrever aspectos nutricionais de idosos com doença de Alzheimer leve a moderada em ambulatório. MÉTODOS: A amostra contou com a participação de 40 idosos de ambos os sexos, diagnosticados com doença da Alzheimer (NINCDS-ADRDA por seleção consecutiva. Foram realizadas avaliações socioeconômicas de atividades de vida diária, antropométrica, clínica e dietética. RESULTADOS: Do total, 65% eram do sexo feminino. Ao se verificar a capacidade funcional, constatou-se que mais de 70% dos idosos mostraram-se independentes para a realização de suas atividades de vida diária. Com base na avaliação do estado nutricional e na gravidade da doença, os idosos encontraram-se eutróficos, com diferença estatisticamente significativa na circunferência do braço entre os graus de demência. Quanto à presença de enfermidades secundárias à doença, 52% dos idosos apresentaram hipertensão arterial sistêmica, seguido de alterações do tipo artrose (17%. O consumo médio de energia e de macronutrientes dos idosos classificados no estágio leve foi de 1645 kcal, distribuídos em 53,7% para carboidratos, 17,5% para proteínas e 28,8% para lipídeos, enquanto que aqueles no estágio moderado foi de 1482 kcal, distribuídos em 59,3% para carboidratos, 16,1% para proteínas e 24,6% para lipídeos. CONCLUSÃO: Neste estudo descritivo de uma amostra ambulatorial de idosos com DA leve e moderada a maior parte deles apresentou estado nutricional de eutrofia, com consumo dietético adequado de carboidratos, proteínas, lipídeos e vitamina C, embora com baixo consumo alimentar de vitamina E.OBJECTIVE: To describe the nutritional status of elderly subjects with mild to moderate Alzheimer's disease.

    It is well-known that to minimize the number of comparisons a binary search tree should be perfectly balanced. Previous work has shown that a dominating factor over the running time for a search is the number of cache faults performed, and that an appropriate memory layout of a binary search tree...... can reduce the number of cache faults by several hundred percent. Motivated by the fact that during a search branching to the left or right at a node does not necessarily have the same cost, e.g. because of branch prediction schemes, we in this paper study the class of skewed binary search trees....... For all nodes in a skewed binary search tree the ratio between the size of the left subtree and the size of the tree is a fixed constant (a ratio of 1/2 gives perfect balanced trees). In this paper we present an experimental study of various memory layouts of static skewed binary search trees, where each...

    Full Text Available Spine is the most common site for skeletal metastasis in patients with malignancy. Vertebral involvement quantification, neurological status, general health status and primary tumor histology are factors to set surgical planning and therapeutic targets. We evaluated the impact of general clinical and neurological status, histologic type and surgery in survival. Method : The study sample consisted of consecutive patients admitted from July 2010 to January 2013 for treatment. Results : Sixty eight patients were evaluated. 23 were female and 45 were male. Main primary neoplasic sites were: breast, prostate, lung/pleura and linfoproliferative. Thirty three out of 68 received surgical treatment, 2 received percutaneous biopsy and 33 had nonsurgical treatment. Survival : Log Rank curves revealed no statistical significant difference according to histological type, surgical approach and Frankel Score. Karnofsky Score was statistically different. Conclusion : Histological type and clinical status were statistically associated with life expectancy in vertebral metastatic disease.

    The aim of the study was to elucidate the interaction and clinical significance between melatonin and cortisol and the status of disease in patients with bronchial asthma. Ten mild persistent and 10 moderate-to-severe persistent asthma patients were recruited to participate in the study. Fifteen normal subjects served as contrds Salivary free melatonin and cortisol were measured simultaneously by radioimmunoassay in all subjects, and 8 salivary samples were collected in a series during a 24-hour period in each subject. The intensity of light was restricted to natural light at room during the daytime and less than 50 lux at night. The results showed that salivary free melatonin levels were significantly lower in mild (15.5 +/- 5.3) micro g/L and moderate-to-severe (7.1 +/- 2.5) micro g/L persistent asthma patients as compared to control subjects (28.9 +/- 8.7) micro g/L (F = 4.47, P cortisol levels were significantly lower in mild (3.1 +/- 0.5) micro g/L and moderate-to-severe (4.2 +/- 0.5) micro g/L persistent asthma patients as compared to control subjects (5.9 +/- 0.7) micro g/L (F = 10.45, P cortisol level was reduced in mild and moderate-to-severe persistent asthma patients, and salivary cortisol peak level was significantly delayed in mild and moderate-to-severe persistent asthma patients (P melatonin and cortisol levels in control and mild persistent asthma patients (r = 0.174, P = 0.057; r = -0.138, P = 0.221, respectively). However, a significant negative correlation was found between the salivary free melatonin and cortisol levels in moderate-to-severe persistent asthma patients (r = -0.275, P = 0.013). There were lower salivary free melatonin and cortisol levels in asthmatic patients. A significant negative correlation was found between melatonin and cortisol levels in moderate-to-severe persistent asthma patients. Furthermore, the reciprocal inhibition of melatonin and cortisol was closely associated with the status of disease in asthmatic patients.

    The conditions of mass exchange in close binary systems with masses of components less or equal to one solar mass have been analysed for the case, when the system radiates gravitational waves. It has been shown that the mass exchange rate depends in a certain way on the mass ratio of components and on the mass of component that fills its inner critical lobe. The comparison of observed periods, masses of contact components, and mass exchange rates of observed cataclysmic binaries have led to the conclusion that the evolution of close binaries WZ Sge, OY Car, Z Cha, TT Ari, 2A 0311-227, and G 61-29 may be driven by the emission of gravitational waves [ru

    The circumstances of mass exchange in close binary systems whose components have a mass < or approx. =1 M/sub sun/ are analyzed for the case where the system is losing orbital angular momentum by radiation of gravitational waves. The mass exchange rate will depend on the mass ratio of the components and on the mass of the component that is overfilling its critical Roche lobe. A comparison of the observed orbital periods, masses of the components losing material, and mass exchange rates against the theoretical values for cataclysmic binaries indicates that the evolution of the close binaries WZ Sge, OY Car, Z Cha, TT Ari, 2A 0311-227, and G61-29 may be driven by the emission of gravitational waves

    Full Text Available We review the main properties, demographics and applications of binary and millisecond radio pulsars. Our knowledge of these exciting objects has greatly increased in recent years, mainly due to successful surveys which have brought the known pulsar population to over 1800. There are now 83 binary and millisecond pulsars associated with the disk of our Galaxy, and a further 140 pulsars in 26 of the Galactic globular clusters. Recent highlights include the discovery of the young relativistic binary system PSR J1906+0746, a rejuvination in globular cluster pulsar research including growing numbers of pulsars with masses in excess of 1.5M_⊙, a precise measurement of relativistic spin precession in the double pulsar system and a Galactic millisecond pulsar in an eccentric (e = 0.44 orbit around an unevolved companion.

    Full Text Available Purpose: We aimed to investigate the current management status of urologic diseases in geriatric hospitals in South Korea. Materials and Methods: Questionnaire surveys and in-depth person-to-person interviews were conducted at 13 hospitals within the Seoul and Incheon areas. Results: The study was carried out from July to December 2014; 75.6% of patients (1,858/2,458 and 77.5% (779/1,031 of medical personnel responded to our survey. All surveys and interviews were performed by urology specialists, fellows, residents, or nurses. The hospitals included in the study had an average of 215.2 beds (range, 110–367, 189.1 patients (range, 90–345, and 40.2 nurses (range, 10–83. The average number of physicians was 6.2 (range, 3–11, but none of these were certified urologists. Only 4 hospitals provided consultation services for urological disorders. In total, 64% of patients had urological disorders, although only 20.7% of patients were receiving medication. Most patients were being treated using urological interventions; diapers (49.7%, indwelling catheters (19.5%, clean intermittent catheters (12.2%, and external collection urinary drainage (7.9%. However, most interventions were inadequately implemented, and only 17% of the patients had been examined by a certified urologist. Urological complications were found in 20.2% of patients, and secondary complications occurred in 18.8%. Excluding redundant cases, the total prevalence of urological complications was 39.0%. Conclusions: Urologic diseases are poorly managed, and no certified urologists work in geriatric hospitals. Therefore, more designated urologists are needed in geriatric hospitals.

  2. The Brightest Binaries

    Vanbeveren, D., Van Rensbergen, W., De Loore, C.

    Massive stars are distributed all over the upper part of the Hertzsprung-Russell diagram according to their subsequent phases of stellar evolution from main sequence to supernova. Massive stars may either be single or they may be a component of a close binary. The observed single star/binary frequency is known only in a small part of the Galaxy. Whether this holds for the whole galaxy or for the whole cosmos is questionable and needs many more high quality observations. Massive star evolution depends critically on mass loss by stellar wind and this stellar wind mass loss may change dramatically when stars evolve from one phase to another. We start the book with a critical discussion of observations of the different types of massive stars, observations that are of fundamental importance in relation to stellar evolution, with special emphasis on mass loss by stellar wind. We update our knowledge of the physics that models the structure and evolution of massive single stars and we present new calculations. The conclusions resulting from a comparison between these calculations and observations are then used to study the evolution of massive binaries. This book provides our current knowledge of a great variety of massive binaries, and hence of a great variety of evolutionary phases. A large number of case studies illustrates the existence of these phases. Finally, we present the results of massive star population number synthesis, including the effect of binaries. The results indicate that neglecting them leads to a conclusion which may be far from reality. This book is written for researchers in massive star evolution. We hope that, after reading this book, university-level astrophysics students will become fascinated by the exciting world of the `Brightest Binaries'.

  3. The effects of socioeconomic status, clinical factors, and genetic ancestry on pulmonary tuberculosis disease in northeastern Mexico.

    Bonnie N Young

    Full Text Available Diverse socioeconomic and clinical factors influence susceptibility to tuberculosis (TB disease in Mexico. The role of genetic factors, particularly those that differ between the parental groups that admixed in Mexico, is unclear. The objectives of this study are to identify the socioeconomic and clinical predictors of the transition from latent TB infection (LTBI to pulmonary TB disease in an urban population in northeastern Mexico, and to examine whether genetic ancestry plays an independent role in this transition. We recruited 97 pulmonary TB disease patients and 97 LTBI individuals from a public hospital in Monterrey, Nuevo León. Socioeconomic and clinical variables were collected from interviews and medical records, and genetic ancestry was estimated for a subset of 142 study participants from 291,917 single nucleotide polymorphisms (SNPs. We examined crude associations between the variables and TB disease status. Significant predictors from crude association tests were analyzed using multivariable logistic regression. We also compared genetic ancestry between LTBI individuals and TB disease patients at 1,314 SNPs in 273 genes from the TB biosystem in the NCBI BioSystems database. In crude association tests, 12 socioeconomic and clinical variables were associated with TB disease. Multivariable logistic regression analyses indicated that marital status, diabetes, and smoking were independently associated with TB status. Genetic ancestry was not associated with TB disease in either crude or multivariable analyses. Separate analyses showed that LTBI individuals recruited from hospital staff had significantly higher European genetic ancestry than LTBI individuals recruited from the clinics and waiting rooms. Genetic ancestry differed between individuals with LTBI and TB disease at SNPs located in two genes in the TB biosystem. These results indicate that Monterrey may be structured with respect to genetic ancestry, and that genetic

    Vitamin D is hypothesized to prevent periodontal disease progression through its immune-modulating properties and its role in maintaining systemic calcium concentrations. The authors investigated associations between plasma 25-hydroxyvitamin D [25(OH)D] (collected 1997 to 2000) and the 5-year change in periodontal disease measures from baseline (1997 to 2000) to follow-up (2002 to 2005) among 655 postmenopausal women in a Women's Health Initiative Observational Study ancillary study. Exploratory analyses were conducted in 628 women who also had 25(OH)D measures at follow-up. Four continuous measures of the 5-year change in periodontal disease were assessed using alveolar crest height (ACH), clinical attachment level (CAL), probing depth (PD), and percentage of gingival sites that bled on assessment. Linear regression was used to estimate β-coefficients, standard errors, and P values corresponding to change in periodontal disease (a 1-mm change in ACH, CAL, or PD or a 1-unit change in the percentage of gingival sites that bled) for a 10-nmol/L difference in 25(OH)D. Models were adjusted for age, education, dental visit frequency, smoking, diabetes status, current medications affecting bone health, baseline measures of periodontal disease, body mass index, and recreational physical activity. No statistically significant associations were observed between baseline 25(OH)D and change in periodontal disease measures, overall or in a subset (n = 442) of women with stable 25(OH)D concentrations [25(OH)D change periodontal disease status. No association between baseline 25(OH)D and the subsequent 5-year change in periodontal disease measures was observed. Vitamin D status may not influence periodontal disease progression. More studies are needed to confirm these results.

    C-reactive protein (CRP) is an acute-phase marker of systemic inflammation and considered an established risk marker for cardiovascular disease (CVD) in old age. Previous studies have suggested that low childhood intelligence, lower socioeconomic status (SES) in childhood or in later life, unhealthy behaviors, poor wellbeing, and high body mass index (BMI) are associated with inflammation. Life course models that simultaneously incorporate all these risk factors can explain how CVD risks accumulate over time, from childhood to old age. Using the data from 1,091 Scottish adults (Lothian Birth Cohort Study, 1936), a path model was constructed to predict CRP at age 70 from concurrent health behaviors, self-perceived quality of life, and BMI and adulthood SES as mediating variables, and from parental SES and childhood intelligence as distal risk factors. A well-fitting path model (CFI = .92, SRMR = .05) demonstrated significant indirect effects from childhood intelligence and parental social class to inflammation via BMI, health behaviors and quality of life (all ps intelligence, unhealthy behaviors, and higher BMI were also direct predictors of CRP. The life course model illustrated how CVD risks may accumulate over time, beginning in childhood and being both direct and transmitted indirectly via low adult SES, unhealthy behaviors, impaired quality of life, and high BMI. Knowledge on the childhood risk factors and their pathways to poor health can be used to identify high-risk individuals for more intensive and tailored behavior change interventions, and to develop effective public health policies.

    The Duke Activity Status Index (DASI) assesses the functional capacity of patients with cardiovascular disease (CVD), but there is no Portuguese version validated for CVD. To translate and adapt cross-culturally the DASI for the Portuguese-Brazil language, and to verify its psychometric properties in the assessment of functional capacity of patients with CVD. The DASI was translated into Portuguese, then checked by back-translation into English and evaluated by an expert committee. The pre-test version was first evaluated in 30 subjects. The psychometric properties and correlation with exercise testing was performed in a second group of 67 subjects. An exploratory factor analyses was performed in all 97 subjects to verify the construct validity of the DASI. The intraclass correlation coefficient for test-retest reliability was 0.87 and for the inter-rater reliability was 0.84. Cronbach's α for internal consistency was 0.93. The concurrent validity was verified by significant positive correlations of DASI scores with the VO 2 max (r = 0.51, p < 0.001). The factor analysis yielded two factors, which explained 54% of the total variance, with factor 1 accounting for 40% of the variance. Application of the DASI required between one and three and a half minutes per patient. The Brazilian version of the DASI appears to be a valid, reliable, fast and easy to administer tool to assess functional capacity among patients with CVD

    The objective of this study was to determine whether blacks with lower extremity peripheral artery disease (PAD) have faster functional decline than whites with PAD. Participants with ankle-brachial index sex, ankle-brachial index, comorbidities, and other confounders (hazard ratio, 1.45; 95% confidence interval, 1.05-1.99; P = .022). This association was attenuated after adjustment for income and education (P = .229). Among 844 participants without baseline mobility impairment, black participants had a higher rate of mobility loss (64/209 [30.6%] vs 164/635 [25.8%]; log-rank, P = .009). Black race was associated with increased mobility loss, adjusting for potential confounders (hazard ratio, 1.42; 95% confidence interval, 1.04-1.94; P = .028). This association was attenuated after additional adjustment for income and education (P = .392) and physical activity (P = .113). There were no racial differences in average annual declines in 6-minute walk, usual-paced 4-meter walking velocity, or fast-paced 4-meter walking velocity. Black PAD patients have higher rates of mobility loss and becoming unable to walk for 6 minutes continuously. These differences appear related to racial differences in socioeconomic status and physical activity. Copyright © 2017 Society for Vascular Surgery. All rights reserved.

    Nutrition is an important issue for elderly people, especially in patients with dementia. It is also related to clinical outcome, such as cognition, autonomy and behavior. The present study investigated the role of nutritional status on cognitive, functional and neuropsychiatric deficits in patients with Alzheimer's disease (AD). Forty-nine patients underwent neuropsychological, nutritional and neuropsychiatric assessments. The sample was divided into at risk of malnutrition (21 patients) and well-nourished (28 patients) according to the Mini Nutritional Assessment (MNA) score. The groups were similar for clinical and demographic variables, except for MNA score and age. The mean body mass index (BMI) was higher than the normal range. Patients at risk of malnutrition showed greater impairment, both in simple and instrumental activities of daily living (ADL and IADL) and a more severe ideomotor praxis deficit than well-nourished patients. Neuropsychiatric symptoms showed significant differences in hallucination, apathy, aberrant motor behavior and night-time subscales of Neuropsychiatric Inventory (NPI). These symptoms were more severe in patients at risk of malnutrition. Logistic regression analysis showed that malnutrition was an important risk factor for the onset of apathy. We hypothesized that changes in dietary habits and intake and the onset of these disorders reflect the involvement of a common neuroanatomical network.

    The Duke Activity Status Index (DASI) assesses the functional capacity of patients with cardiovascular disease (CVD), but there is no Portuguese version validated for CVD. To translate and adapt cross-culturally the DASI for the Portuguese-Brazil language, and to verify its psychometric properties in the assessment of functional capacity of patients with CVD. The DASI was translated into Portuguese, then checked by back-translation into English and evaluated by an expert committee. The pre-test version was first evaluated in 30 subjects. The psychometric properties and correlation with exercise testing was performed in a second group of 67 subjects. An exploratory factor analyses was performed in all 97 subjects to verify the construct validity of the DASI. The intraclass correlation coefficient for test-retest reliability was 0.87 and for the inter-rater reliability was 0.84. Cronbach's α for internal consistency was 0.93. The concurrent validity was verified by significant positive correlations of DASI scores with the VO{sub 2}max (r = 0.51, p < 0.001). The factor analysis yielded two factors, which explained 54% of the total variance, with factor 1 accounting for 40% of the variance.

    Full Text Available Cognitive impairment and depressive symptoms are of great interest in Parkinson’s disease (PD, since they are very common and lead to increased disability with poor quality of life. Inflammatory mechanisms have been implicated in PD and its nonmotor symptoms. In the current pilot study, we aimed to evaluate plasma levels of chemokines in PD patients and to analyze the putative association of chemokines with depressive symptoms and cognitive performance. We hypothesized that higher chemokines levels are associated with worse cognitive performance and increased depressive symptoms in PD. For this purpose, 40 PD patients and 25 age- and gender-matched controls were subjected to a clinical evaluation including cognitive and mood tests. Peripheral blood was drawn and plasma levels of CCL2/MCP-1, CCL11/eotaxin, CCL24/eotaxin-2, and CXCL10/IP-10 were measured by enzyme-linked immunosorbent assay. PD patients and control individuals presented comparable plasma concentrations of all the evaluated chemokines. In PD patients, CXCL10/IP-10 plasma levels correlated positively with Hoehn and Yahr staging scale. In addition, the higher CXCL10/IP-10 levels, the worse performance on cognitive tests. Although there was no significant difference between PD patients and control individuals regarding chemokines levels, our preliminary results showed that CXCL10/IP-10 may be associated with cognitive status in PD.

    A study was made of the bone marrow status in unirradiated zones on 33 patients with stage 1-2 Hodgkin's disease in complete 9-12 year remission after therapeutic irradiation of the lymphatic collectors of the upper part of the trunk in combination with irradiation of the system (16 patients) or splenectomy (17 patients). The total count of myelokaryocytes, myelogram, a relative and absolute content of lymphoid cells, immature granulocytes and elements of the erythroid series were defined in the punctates of the upper portion of the ilium. T- and B-lymphocyte count, the number of granulocytomacrophage (CFU-C) and stromal (CFU-F) precursor cells were defined using morphocytochemical and immunological methods. At that time an increase in the relative and absolute content of C- ad B-lymphocytes was noted. The T-cell count and the total number of myelokaryocytes, on the one hand, and the content of immature granulocytes and erythronormoblasts, on the other had, showed correlation of various degree which was particularly noticeable in the group of unoperated patients. The total number of myelokaryocytes in 1 μl of the bone marrow of the patients after splenectomy, on an average, significantly exceeded that in the group of patients with the irradiated spleen. These changes were considered to be a result of the rearragement of T-differentiating lymphocytes with their raised accumulation in the bone marrow after irradiation of a considerable volume of the lymphoid tissue and spleen or after splenectomy

    Gravitational encounters of pairs of binaries have been studied numerically. Various cross-sections have been calculated for qualitative final results of the interaction and for energy transfer between the binding energy and the centre of mass kinetic energy. The distribution of the kinetic energies, resulting from the gravitational collision, were found to be virtually independent of the impact velocity in the case of collision of hard binaries. It was found that one out of five collisions, which are not simple fly-by's, leads to the formation of a stable three-body system. (author)

    Full Text Available Our knowledge of binary and millisecond pulsars has greatly increased in recent years. This is largely due to the success of large-area surveys which have brought the known population of such systems in the Galactic disk to around 50. As well as being interesting as a population of astronomical sources, many pulsars turn out to be superb celestial clocks. In this review we summarise the main properties of binary and millisecond pulsars and highlight some of their applications to relativistic astrophysics.

    Full Text Available We review the main properties, demographics and applications of binary and millisecond radio pulsars. Our knowledge of these exciting objects has greatly increased in recent years, mainly due to successful surveys which have brought the known pulsar population to over 1700. There are now 80 binary and millisecond pulsars associated with the disk of our Galaxy, and a further 103 pulsars in 24 of the Galactic globular clusters. Recent highlights have been the discovery of the first ever double pulsar system and a recent flurry of discoveries in globular clusters, in particular Terzan 5.

    2017-04-01

    The Latin American and Caribbean region (LAC) is a leading global producer and exporter of animal products. Its livestock production systems are diverse, ranging from large-scale commercial enterprises to family farms. Countries in this region have sought to improve their animal health status through both public and private efforts. Despite significant advances in eradicating such diseases as foot and mouth disease and classical swine fever, other animal health challenges remain; constraining exports, causing negative economic impacts and threatening food security. Obtaining certification of disease-free status is only the first step towards gaining benefits from improvements in animal health. Increasing international trade means that countries must manage the sustainability of their disease-free status in conjunction with trade partners and must comply with additional food safety and animal welfare standards. This paper comments on the challenges created by this new scenario in relation to the epidemiology and economics of animal health, when seeking to improve decisionmaking for animal health management. The authors characterise the current LAC livestock landscape and animal health situation, describing transitions in disease control and the use of economics in improving animal health. They conclude with remarks on the challenges presented by decision-making, economic rationality, sources of benefits, distribution and incentives.

    Clinical trials have shown the efficacy of adalimumab in Crohn's disease, but the outcome in regular practice remains unknown. The aim of the study was to examine clinical status, quality of life, and work productivity of Crohn's disease patients receiving adalimumab for one year in the context of usual clinical practice. This was a prospective, observational study with a one-year follow-up. After baseline, Crohn's disease patients were evaluated at 1, 3, 6, 9, and 12 months after starting treatment with adalimumab. Outcome variables included: clinical status (measured with CDAI), quality of life (measured with EuroQoL-5D and IBDQ), and work productivity (measured with WPAI questionnaire). These outcome variables were compared using the Student's t test or Wilcoxon test for paired comparison data according to the data distribution. Statistical significance was set at two-sided p work productivity impact decreased from 53% to 24% (p quality of life and work productivity.

    Short-term nutritional supplements enable an improvement in Alzheimer patients' nutritional status, but it remains to be seen whether they will be sufficient to improve long-term nutritional status. The aim of this study was to evaluate the long-term impact of a 3-week nutritional supplementation on the nutritional status of undernourished patients with probable mild Alzheimer disease. A 21-day prospective randomized nonblinded controlled trial was conducted. Patients were followed-up for an additional period until the 90th day after the beginning of the intervention. Intervention resulted in significant improvements in Mini Nutritional Assessment (MNA) score [Mean=1.4, standard deviation (SD)=0.8 vs. 0.0 (0.1) in the control group, PAlzheimer disease (AD) patients' nutritional status. Further improvements in the AD patients' MNA mean score=1.4 (SD=2.3) versus -0.5 (SD=0.6) in the control group (P=0.003) were seen at 90 days follow-up. Data show that a 3-week nutritional supplementation has a positive long-term impact on the nutritional status of undernourished patients with mild probable AD.

    This study aimed to identify those comorbidities with greatest impact on patient-reported health status in patients with chronic obstructive pulmonary disease (COPD) and to develop a comorbidity index that reflects their combined impact. We included 408 Swiss and Dutch primary care patients with COPD from the International Collaborative Effort on Chronic Obstructive Lung Disease: Exacerbation Risk Index Cohorts (ICE COLD ERIC) in this cross-sectional analysis. Primary outcome was the Feeling Thermometer, a patient-reported health status instrument. We assessed the impact of comorbidities at five cohort assessment times using multiple linear regression adjusted for FEV1, retaining comorbidities with associations P ≤ 0.1. We developed an index that reflects strength of association of comorbidities with health status. Depression (prevalence: 13.0%; regression coefficient: -9.00; 95% CI: -13.52, -4.48), anxiety (prevalence: 11.8%; regression coefficient: -5.53; 95% CI -10.25, -0.81), peripheral artery disease (prevalence: 6.4%; regression coefficient: -5.02; 95% CI-10.64, 0.60), cerebrovascular disease (prevalence: 8.8%; regression coefficient: -4.57; 95% CI -9.43, 0.29), and symptomatic heart disease (prevalence: 20.3%; regression coefficient: -3.81; 95% CI -7.23, -0.39) were most strongly associated with the Feeling Thermometer. These five comorbidities, weighted, compose the COMorbidities in Chronic Obstructive Lung Disease (COMCOLD) index. The COMCOLD index reflects the combined impact of five important comorbidities from patients' perspective and complements existing comorbidity indices that predict death. It may help clinicians focus on comorbidities affecting patients' health status the most. Copyright © 2014 The Authors. Published by Elsevier Inc. All rights reserved.

    Papillary thyroid carcinoma (PTC) accounts for about 80% of the cases in thyroid cancer. Routine surveillance by serum thyroglobulin (Tg) and medical imaging is the current practice to monitor disease progression of the patients. Whether enumeration of circulating epithelial cells (CECs) helps to define disease status of PTC patients was investigated. CECs were enriched from the peripheral blood of the healthy control subjects (G1, n = 17) and the patients at disease-free status (G2, n = 26) or with distant metastasis (G3, n = 22). The number of CECs expressing epithelial cell adhesion molecule (EpCAM) or thyroid-stimulating hormone receptor (TSHR) was determined by immunofluorescence microscopy analyses. The medium number of EpCAM+-CECs was 6 (interquartile range 1-11), 12 (interquartile range 7-16) and 91 (interquartile range 31-206) cells/ml of blood for G1, G2 and G3, respectively. EpCAM+-CEC counts were significantly higher in G3 than in G1 (p interquartile range 3-13), 16 (interquartile range 10-24) and 100 (interquartile range 31-226) cells/ml of blood for G1, G2 and G3, respectively. The TSHR+-CEC counts also distinguished G3 from G1 (p < 0.05) and G2 (p < 0.05). With an appropriate cut off value of CEC count, the disease status for 97.9% (47/48) of the cases was clearly defined. Notably, the metastatic disease for all patients in G3 (22/22) was revealed by combined analysis of serum Tg and CEC. This study implicates that CEC testing can supplement the current standard methods for monitoring disease status of PTC.

    Full Text Available Factors related with hyperhomocysteinemia (HHcy and the impact of HHcy in Parkinson’s disease (PD are not well understood. We investigated the factors associated with increased levels of homocysteine (Hcy and the relationship between HHcy and motor symptoms, cognitive status, and vascular risk in patients with Parkinson’s disease. Among 60 patients (29 males, 48.3% with PD, the stage of the disease, the severity of clinical symptoms, and the patients’ cognitive status were measured using a modified Hoehn and Yahr Staging Scale (mHY, Unified Parkinson’s Disease Rating Scale (UPDRS II and III, and Mini-Mental State Examination (MMSE, respectively. Patients were also noted for having dyskinesia and hallucinations. Serum vitamin B12, folic acid, and plasma Hcy ​​levels were measured. Furthermore, the presence of vascular risk factors was recorded. Finally, we investigated carotid artery intima-media thickening and stenosis using colour Doppler ultrasonography as well as the presence of ischemic lesions using brain imaging techniques. Plasma Hcy ​​levels were higher with advanced age and in males. In addition, there was an inverse relationship between Hcy ​​and vitamin B12 levels. There was no correlation between HHcy and the stage of the disease, severity of motor symptoms, cognitive status as assessed by the MMSE, vascular risk factors, carotid artery atherosclerotic findings, and ischemic brain lesions. Plasma Hcy levels may rise due to several factors in PD. However, the resulting HHcy has no significant effect on the clinical picture in terms of motor features, cognitive status, and vascular diseases.

    Recently, malnutrition has been shown to be related to worse clinical outcomes in patients with heart failure. However, the association between nutritional status and clinical outcomes in patients with coronary artery disease (CAD) remains unclear. We investigated the prognostic value of malnutrition assessed by the Controlling Nutritional Status (CONUT; range 0-12, higher = worse, consisting of serum albumin, cholesterol and lymphocytes) score in patients with CAD. The CONUT score was measured on admission in a total of 1987 patients with stable CAD who underwent elective percutaneous coronary intervention (PCI) between 2000 and 2011. Patients were divided into two groups according to their CONUT score (0-1 vs. ≥2). The incidence of major adverse cardiac events (MACE), including all-cause death and non-fatal myocardial infarction, was evaluated. The median CONUT score was 1 (interquartile range 0-2). During the median follow-up of 7.4 years, 342 MACE occurred (17.2%). Kaplan-Meier curves revealed that patients with high CONUT scores had higher rates of MACE (log-rank p Nutritional status assessed by the CONUT score was significantly associated with long-term clinical outcomes in patients with CAD. Pre-PCI assessment of the CONUT score may provide useful prognostic information.

    Full Text Available Background: Investigators have identified an association of socio-demographic and medical factors with periodontal risk. This study observed status and association of periodontal disease and associated risk factors/indictors. Materials and Methods: All patients attending a dental teaching hospital were interviewed for socio-demographic and medical information through a structured questionnaire. Participants were examined for periodontal status using the community periodontal index (CPI, by a single examiner during September to November 2012. An association of age, gender, smoking habit, systemic conditions, and oral hygiene measures with periodontal status ([periodontitis CPI score ≥3]/nonperiodontitis [CPI score ≤2] was analyzed by applying Chi-square test and forward selection stepwise regression analysis. Results: One thousand nine hundred and eighteen patients were examined during the study period. The findings revealed that 63.5% of the subjects had CPI score ≤2 (nonperiodontitis, while 34.5% were found with CPI score ≥3 (periodontitis. Age, gender, occupation, smoking, diabetes, arthritis, cardiovascular disease, kidney disease, stress, medications, and oral hygiene habits of using tooth powder or tooth brushing were significantly (P ≤ 0.037 associated with periodontal status. Regression analysis showed a significant association of age, occupation, and smoking with periodontitis. Conclusion: This study observed prevalence of periodontitis in one-fourth of study sample. The study confirmed various socio-demographic risk factors/indictors associated with increased risk of periodontitis.

    Alzheimer disease (AD) patients are at risk of nutritional insufficiencies because of physiological and psychological factors. Nutritional compounds are postulated to play a role in the pathophysiological processes that are affected in AD. We here provide the first systematic review and meta-analysis that compares plasma levels of micronutrients and fatty acids in AD patients to those in cognitively intact elderly controls. A secondary objective was to explore the presence of different plasma nutrient levels between AD and control populations that did not differ in measures of protein/energy nourishment. We screened literature published after 1990 in the Cochrane Central Register of Controlled Trials, Medline, and Embase electronic databases using Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines for AD patients, controls, micronutrient, vitamins, and fatty acids, resulting in 3397 publications, of which 80 met all inclusion criteria. Status of protein/energy malnutrition was assessed by body mass index, mini nutritional assessment score, or plasma albumin. Meta-analysis, with correction for differences in mean age between AD patients and controls, was performed when more than five publications were retrieved for a specific nutrient. We identified five or more studies for folate, vitamin A, vitamin B12, vitamin C, vitamin D, vitamin E, copper, iron, and zinc but fewer than five studies for vitamins B1 and B6, long-chain omega-3 fatty acids, calcium, magnesium, manganese, and selenium (the results of the individual publications are discussed). Meta-analysis showed significantly lower plasma levels of folate and vitamin A, vitamin B12, vitamin C, and vitamin E (P vitamin D (P = .075) were found in AD patients. No significant differences were observed for plasma levels of copper and iron. A meta-analysis that was limited to studies reporting no differences in protein/energy malnourishment between AD and control populations yielded

    Neonates with single ventricle congenital heart disease are at risk for structural cerebral abnormalities. Little is known about the further evolution of cerebral abnormalities until Fontan procedure. Between August 2012 and July 2015, we conducted a prospective cross-sectional two centre study using cerebral magnetic resonance imaging (MRI) and neuro-developmental outcome assessed by the Bayley-III. Forty-seven children (31 male) were evaluated at a mean age of 25.9 ± 3.4 months with hypoplastic left heart syndrome (25) or other single ventricle (22). Cerebral MRI was abnormal in 17 patients (36.2%) including liquor space enlargements (10), small grey (9) and minimal white (5) matter injuries. Eight of 17 individuals had combined lesions. Median (range) cognitive composite score (CCS) (100, 65-120) and motor composite score (MCS) (97, 55-124) were comparable to the reference data, while language composite score (LCS) (97, 68-124) was significantly lower ( P  = 0.040). Liquor space enlargement was associated with poorer performance on all Bayley-III subscores (CCS: P  = 0.02; LCS: P  = 0.002; MCS: P  = 0.013). The number of re-operations [odds ratio (OR) 2.2, 95% confidence interval (CI) 1.1-4.3] ( P  = 0.03) and re-interventions (OR 2.1, 95% CI 1.1-3.8) ( P  = 0.03) was associated with a higher rate of overall MRI abnormalities. Cerebral MRI abnormalities occur in more than one third of children with single ventricle, while the neuro-developmental status is less severely affected before Fontan procedure. Liquor space enlargement is the predominant MRI finding associated with poorer neuro-developmental status, warranting further studies to determine aetiology and further evolution until school-age. © The Author 2016.

The above information inspired us to evaluate the nutritional status in these patients by measuring daily oral intake and anthropom etric measures. METHOD : This cross - sectional study was conducted during the period October 2008 to April 2009. Seventy two COPD patients in the age group of 40 - 65 years, with an FEV (1 < 65% of predicted and an FEV (1/FVC ratio < 70% were included in the study. All the patients were assessed for anthropometric parameters such as height, body weight (BW, Body Mass Index (BMI, Hip Circumference, waist circumference and mid upper arm circumference (MUAC. Daily dietary intakes were calculated by 24 hour re call method with the help of cups, spoons, and glasses which were standardized with commonly consumed recipes. Standardized models of chapatti, rice, fruits, and snacks items were used for accurate data. Energy and nutrient intakes were derived using the N utritive value of Indian foods. RESULTS : The prevalence of under nutrition were (30/72 41.6% based on body mass index (<18.5 kg/m(2 and (46/72 63.8% based on mid - upper arm circumference (<24 cm.More number of patients was above 60 years of age in the income grouping 3000 - 5000 INR / month living with family members of more than 3 per house. The daily intake of food as compared to reference RDA is as follows energy 54.51%, carbohydrates 84.85%, protein60.52% and Fats 71.2%. CONCLUSION : The prevalence of u nder nutrition were (30/72 41.6% based on body mass index (<18.5 kg/m2 and (46/72 63.8% based on mid - upper arm circumference (<24 cm . Nutritional assessment should be made mandatory in order to recognize

    Importance Long-term multivitamin use had no effect on risk of cardiovascular disease (CVD) in the Physicians’ Health Study II. Baseline nutritional status may have modified the lack of effect. Objective To investigate effect modification by various baseline dietary factors on CVD risk in the Physicians’ Health Study II. Design, Setting, and Participants The Physicians’ Health Study II was a randomized, double-blind, placebo-controlled trial testing multivitamin use (multivitamin [Centrum Silver] or placebo daily) among US male physicians. The Physicians’ Health Study II included 14 641 male physicians 50 years or older, 13 316 of whom (91.0%) completed a baseline 116-item semiquantitative food frequency questionnaire and were included in the analyses. This study examined effect modification by baseline intake of key foods, individual nutrients, dietary patterns (Alternate Healthy Eating Index and Alternate Mediterranean Diet Score), and dietary supplement use. The study began in 1997, with continued treatment and follow-up through June 1, 2011. Interventions Multivitamin or placebo daily. Main Outcomes and Measures Major cardiovascular events, including nonfatal myocardial infarction, nonfatal stroke, and CVD mortality. Secondary outcomes included myocardial infarction, total stroke, CVD mortality, and total mortality individually. Results In total, 13 316 male physicians (mean [SD] age at randomization, 64.0 [9.0] years in those receiving the active multivitamin and 64.0 [9.1] years in those receiving the placebo) were observed for a mean (SD) follow-up of 11.4 (2.3) years. There was no consistent evidence of effect modification by various foods, nutrients, dietary patterns, or baseline supplement use on the effect of multivitamin use on CVD end points. Statistically significant interaction effects were observed between multivitamin use and vitamin B6 intake on myocardial infarction, between multivitamin use and vitamin D intake on CVD mortality

    Work and marital status have been shown to be associated with health outcome in women. However, the effect of employment and marriage on psychosocial functioning has been studied predominantly in healthy subjects. We investigated whether work and marital status are associated with depressive symptoms, social support, and daily stress behavior in women with coronary artery disease (CAD). Data of 105 women with CAD and of working age were analyzed. General linear models were used to determine the association between work and marital status and depressive symptoms, social support, and daily stress behavior. Women who were working at the time of measurement had lower levels of depressive symptoms (7.0 +/- 1.2 vs. 12.1 +/- 0.9, p women, whereas marital status was not related to any of the outcome variables. Results were similar after adjusting for potential confounders, that is, age, education, self-reported health, and risk factors for CAD. There was no significant interaction between marital status and working status on depressive symptoms, social support, or daily stress behavior. In women with CAD, all working had lower levels of depressive symptoms and a better social integration than those not working, regardless of reason for being nonemployed. Daily stress behavior, depression, and social support did not differ between cohabiting and not cohabiting women. Future interventions should take into consideration that women with CAD who are unemployed may have a higher risk for depression and social isolation and, therefore, poor clinical outcomes.

    To investigate the nutritional status of children on maintenance hemodialysis due to stage 5 chronic kidney disease (CKD) and the clinical significance of nutritional assessment indices. A total of 21 children on maintenance hemodialysis due to stage 5 CKD were grouped according to body mass index. The nutritional status was assessed based on anthropometric parameters, biochemical parameters, inflammatory factors, residual renal function, indices of dialysis adequacy, and resting energy expenditure. Related indices were compared between the children with malnutrition and those with normal nutritional status. Of the 21 children, 10 had malnutrition and 11 had normal nutritional status. There were significant differences between the two groups in anthropometric parameters, levels of leptin, insulin-like growth factor-1, interleukin-1, interleukin-6, and tumor necrosis factor-α, and mean 24-hour residual urine volume (Pnutritional status of children with stage 5 CKD on maintenance hemodialysis. Further studies are needed to investigate the value of the measurement of resting energy expenditure in the evaluation and monitoring of nutritional status in children with stage 5 CKD on maintenance hemodialysis.

    Full Text Available Vitamin D has a potential role in slowing HIV disease progression and preventing mortality based on its extensive involvement in the immune system; however, this relationship has not been examined in large studies or in resource-limited settings.Vitamin D levels were assessed in 884 HIV-infected pregnant women at enrollment in a trial of multivitamin supplementation (not including vitamin D in Tanzania. Women were followed up for a median of 69.5 months, and information on hemoglobin levels, HIV disease progression, and mortality was recorded. Proportional hazard models and generalized estimating equations were used to assess the relationship of these outcomes with vitamin D status.Low vitamin D status (serum 25-hydroxyvitamin D<32 ng/mL was significantly associated with progression to WHO HIV disease stage III or greater in multivariate models (incidence rate ratio [RR]: 1.25; 95% confidence intervals [CI]: 1.05, 1.50. No significant relationship was observed between vitamin D status and T-cell counts during follow-up. Women with low vitamin D status had 46% higher risk of developing severe anemia during follow-up, compared to women with adequate vitamin D levels (RR: 1.46; 95% CI: 1.09, 1.96. Women in the highest vitamin D quintile had a 42% lower risk of all-cause mortality, compared to the lowest quintile (RR: 0.58; 95% CI: 0.40, 0.84. Vitamin D status had a protective association with HIV disease progression, all-cause mortality, and development of anemia during follow-up in HIV-infected women. If confirmed in randomized trials, vitamin D supplementation could represent a simple and inexpensive method to prolonging the time to initiation of antiretroviral therapy in HIV-infected patients, particularly in resource-limited settings.

    Full Text Available Background: Growth failure and delayed puberty are well known features of children and adolescents with inflammatory bowel disease (IBD, in addition to the chronic course of the disease. Urinary metabonomics was applied in order to better understand metabolic changes between healthy and IBD children. Methods: 21 Pediatric patients with IBD (mean age 14.8 years, 8 males were enrolled from the Pediatric Gastroenterology Outpatient Clinic over two years. Clinical and biological data were collected at baseline, 6, and 12 months. 27 healthy children (mean age 12.9 years, 16 males were assessed at baseline. Urine samples were collected at each visit and subjected to 1H Nuclear Magnetic Resonance (NMR spectroscopy. Results: Using 1H NMR metabonomics, we determined that urine metabolic profiles of IBD children differ significantly from healthy controls. Metabolic differences include central energy metabolism, amino acid, and gut microbial metabolic pathways. The analysis described that combined urinary urea and phenylacetylglutamine—two readouts of nitrogen metabolism—may be relevant to monitor metabolic status in the course of disease. Conclusion: Non-invasive sampling of urine followed by metabonomic profiling can elucidate and monitor the metabolic status of children in relation to disease status. Further developments of omic-approaches in pediatric research might deliver novel nutritional and metabolic hypotheses.

  17. Profiles of extracellular miRNA in cerebrospinal fluid and serum from patients with Alzheimer's and Parkinson's diseases correlate with disease status and features of pathology.

    Directory of Open Access Journals (Sweden)

    Full Text Available The discovery and reliable detection of markers for neurodegenerative diseases have been complicated by the inaccessibility of the diseased tissue--such as the inability to biopsy or test tissue from the central nervous system directly. RNAs originating from hard to access tissues, such as neurons within the brain and spinal cord, have the potential to get to the periphery where they can be detected non-invasively. The formation and extracellular release of microvesicles and RNA binding proteins have been found to carry RNA from cells of the central nervous system to the periphery and protect the RNA from degradation. Extracellular miRNAs detectable in peripheral circulation can provide information about cellular changes associated with human health and disease. In order to associate miRNA signals present in cell-free peripheral biofluids with neurodegenerative disease status of patients with Alzheimer's and Parkinson's diseases, we assessed the miRNA content in cerebrospinal fluid and serum from postmortem subjects with full neuropathology evaluations. We profiled the miRNA content from 69 patients with Alzheimer's disease, 67 with Parkinson's disease and 78 neurologically normal controls using next generation small RNA sequencing (NGS. We report the average abundance of each detected miRNA in cerebrospinal fluid and in serum and describe 13 novel miRNAs that were identified. We correlated changes in miRNA expression with aspects of disease severity such as Braak stage, dementia status, plaque and tangle densities, and the presence and severity of Lewy body pathology. Many of the differentially expressed miRNAs detected in peripheral cell-free cerebrospinal fluid and serum were previously reported in the literature to be deregulated in brain tissue from patients with neurodegenerative disease. These data indicate that extracellular miRNAs detectable in the cerebrospinal fluid and serum are reflective of cell-based changes in pathology and can

    MicroRNAs are key players in cardiac stress responses, but the mRNAs, whose abundance and translational potential are primarily affected by changes in cardiac microRNAs, are not well defined. Stimulus-induced, large-scale alterations in the cardiac transcriptome, together with consideration of the law of mass action, further suggest that the mRNAs most substantively targeted by individual microRNAs will vary between unstressed and stressed conditions. To test the hypothesis that microRNA target profiles differ in health and disease, we traced the fate of empirically determined miR-133a and miR-378 targets in mouse hearts undergoing pressure overload hypertrophy. Ago2 immunoprecipitation with RNA sequencing (RNA-induced silencing complex sequencing) was used for unbiased definition of microRNA-dependent and microRNA-independent alterations occurring among ≈13 000 mRNAs in response to transverse aortic constriction (TAC). Of 37 direct targets of miR-133a defined in unstressed hearts (fold change ≥25%, false discovery rate the effect of TAC on microRNA direct target selection resulted in widespread alterations of signaling function. Numerous microRNA-mediated regulatory events occurring exclusively during pressure overload revealed signaling networks that may be responsive to the endogenous decreases in miR-133a during TAC. Pressure overload-mediated changes in overall cardiac RNA content alter microRNA targeting profiles, reinforcing the need to define microRNA targets in tissue-, cell-, and status-specific contexts. © 2015 American Heart Association, Inc.

    Background/Aims Dementia is a worldwide public health problem and there are several diagnostic tools for its assessment. The aim of this study was to evaluate the performance of the Memory Alteration Test (M@T) to discriminate between patients with early Alzheimer's disease (AD), patients with amnestic mild cognitive impairment (a-MCI), and subjects with a cognitively healthy status (CHS). Methods The discriminative validity was assessed in a sample of 90 patients with AD, 45 patients with a-MCI, and 180 subjects with CHS. Clinical, functional, and cognitive studies were independently performed in a blinded fashion and the gold standard diagnosis was established by consensus on the basis of these results. The test performance was assessed by means of a receiver operating characteristic curve analysis as area under the curve (AUC). Results M@T mean scores were 17.7 (SD = 5.7) in AD, 30.8 (SD = 2.3) in a-MCI, and 44.5 (SD = 3.1) in CHS. A cutoff score of 37 points had a sensitivity of 98.3% and a specificity of 97.8% to differentiate a-MCI from CHS (AUC = 0.999). A cutoff score of 27 points had a sensitivity of 100% and a specificity of 98.9% to differentiate mild AD from a-MCI and from CHS (AUC = 1.000). Conclusions The M@T had a high performance in the discrimination between early AD, a-MCI and CHS. PMID:25298775

    Temporal trends of myocardial perfusion imaging (MPI) among diabetics and non-diabetics and the influence of gender and prior coronary artery disease (CAD) status has not been previously investigated. Consecutive patients who underwent clinically indicated stress-MPI over a 17-year period (1996 through 2012) were studied. Data were collected prospectively as a part of the ongoing clinical databases. Study patients were divided into 4 temporal subgroups (1996 to 2000, 2001 to 2004, 2005 to 2008 and 2009 to 2012) to compare the trends of cardiac risk factors and the frequency of abnormal and ischemic MPI. Of 78,344 total stress MPI studies, 30.2% were in diabetics. The frequency of abnormal MPI studies, while substantially higher in diabetics, significantly declined over time both in diabetics (53.6% in 1996 to 39.8% in 2012) and non-diabetics (37% in 1996 to 27.4% in 2012), despite an increase in the cardiac risk factor profile. Furthermore, among patients with no known CAD, the temporal prevalence of abnormal MPI was highest in diabetic men (57.5% in 1996 to 31.9% in 2012), lowest in non-diabetic women (18.8% in 1996 to 11% in 2012), and both intermediate and comparable in non-diabetic men and diabetic women (36.4% and 35.7% in 1996 and 20.7% and 17.5% in 2012, respectively). Despite a temporal reduction in the prevalence of abnormal studies from 1996 through 2012, stress MPI continues to play an important clinical role, particularly in diabetics, men and patients with known-CAD.

    OBJECTIVE To investigate the impact of iron status on survival in patients with type 2 diabetes and coronary artery disease (CAD). RESEARCH DESIGN AND METHODS Serum ferritin, transferrin saturation (Tsat), and soluble transferrin receptor (sTfR) were measured in 287 patients with type 2 diabetes and stable CAD (65 ± 9 years of age, 78% men). RESULTS During a mean follow-up of 45 ± 19 months, there were 59 (21%) deaths and 60 (21%) cardiovascular hospitalizations. Both serum ferritin and sTfR strongly predicted 5-year all-cause mortality rates, independently of other variables (including hemoglobin, measures of renal function, inflammation, and neurohormonal activation). There was an exponential relationship between sTfR and mortality (adjusted hazard ratio [HR] per 1 log mg/L: 4.24 [95% CI 1.43–12.58], P = 0.01), whereas the relationship between ferritin and mortality was U-shaped (for the lowest and the highest quintiles vs. the middle quintile [reference group], respectively: adjusted HR 7.18 [95% CI 2.03–25.46], P = 0.002, and adjusted HR 5.12 [1.48–17.73], P = 0.01). Similar patterns were observed for the composite outcome of all-cause mortality or cardiovascular hospitalization, and in these multivariable models, low Tsat was related to unfavorable outcome. CONCLUSIONS Both low and high serum ferritin (possibly reflecting depleted and excessive iron stores, respectively) along with high serum sTfR (reflecting reduced metabolically available iron) identify patients with type 2 diabetes and CAD who have a poor prognosis.

    Patients with epithelial ovarian cancer have a poor prognosis and often undergo intensive treatment. These patients are therefore at risk for experiencing distress and reduced quality of life. The aim of this study was to explore the self-reported distress severity, experienced problems, and quality of life in relation to their disease status. This cross-sectional study was conducted in 2011 at a University Medical Center. Women with ovarian cancer (n = 273), both during and after treatment, were asked by mail to fill in self-report questionnaires. Distress was measured using with the Distress Thermometer (DT), Hospital Anxiety and Depression Scale, and Impact of Event Scale. Problems and quality of life were assessed with the problem list of the DT, and European Organization for Research and Treatment of Cancer Quality of Life C-30 and OV28. The questionnaire data of 104 patients were analyzed. Screening with the DT revealed distress in 32% [mean (SD), 3.1 (2.6)]. Distress was found with the Hospital Anxiety and Depression Scale in 14% [8.6 (5.9)] and with the Impact of Event Scale in 18% of the patients [17.5 (15.5)]. No significant differences were found in distress severity and self-reported problems between patients with and without recurrence. In both groups, the problems fatigue, condition, and neuropathy were most reported. Patients with distress (DT ≥ 5) experienced significantly worse functioning, more problems, and lower quality of life than patients without distress (P influence on distress, quality of life, and the problems encountered. However, distressed patients experienced more problems, with physical and emotional functioning, and had lower quality of life. The problems fatigue, physical condition, and neuropathy are the most prevailing.

    In order to understand the current status and trends of the important parasitic diseases in human population, to evaluate the effect of control activities in the past decade and provide scientific base for further developing control strategies, a national survey was carried out in the country (Taiwan, Hongkong and Macau not included) from June, 2001 to 2004 under the sponsorship of the Ministry of Health. The sample sizes of the nationwide survey and of the survey in each province (autonomous region and municipality, P/A/M) were determined following a calculating formula based on an estimation of the sample size of random sampling to the rate of population. A procedure of stratified cluster random sampling was conducted in each province based on geographical location and economical condition with three strata: county/city, township/town, and spot, each spot covered a sample of 500 people. Parasitological examinations were conducted for the infections of soil-transmitted nematodes, Taenia spp, and Clonorchis sinensis, including Kato-Katz thick smear method, scotch cellulose adhesive tape technique and test tube-filter paper culture (for larvae). At the same time, another sampled investigation for Clonorchis sinensis infection was carried out in the known endemic areas in 27 provinces. Serological tests combined with questionnaire and/or clinical diagnosis were applied for hydatid disease, cysticercosis, paragonimiasis, trichinosis, and toxoplasmosis. A total sampled population of 356 629 from the 31 P/A/M was examined by parasitological methods and 26 species of helminth were recorded. Among these helminth, human infections of Metorchis orientalis and Echinostoma aegypti were detected in Fujian Province which seemed to be the first report in the world, and Haplorchis taichui infection in Guangxi Region was the first human infection record in the country. The overall prevalence of helminth infections was 21.74%. The prevalence of soil-transmitted nematodes was 19

    The association between bronchial obstruction severity and mortality in Chronic Obstructive Pulmonary Disease (COPD) is well established, but it is unknown whether disease-specific health status measures and multidimensional assessment (MDA) have comparable prognostic value. We analyzed data coming from the Salute Respiratoria nell'Anziano (Respiratory Health in the Elderly--SaRA) study, enrolling elderly people attending outpatient clinics for respiratory and non-respiratory problems. From this population we selected 449 patients with bronchial obstruction (77.3% men, mean age 73.1). We classified patients' health status using tertiles of the Saint George Respiratory Questionnaire (SGRQ) and a MDA including functional (the 6' walking test, WT), cognitive (Mini-Mental State Examination, MMSE) and affective status (Geriatric Depression Scale, GDS). The agreement of the classification methods was calculated using the kappa statistic, and survival associated with group membership was evaluated using survival analysis. Pulmonary function, expressed by the FEV1, worsened with increasing SGRQ or MDA scores. Cognitive function was not associated with the SGRQ, while physical performance and mood status were impaired only in the highest tertile of SGRQ. A poor agreement was found between the two classification systems tested (k = 0.194). Compared to people in the first tertile of SGRQ score, those in the second tertile had a sex-adjusted HR of 1.22 (0.75-1.98) and those in the third tertile of 2.90 (1.92-4.40). The corresponding figures of the MDA were 1.49 (95% CI 1.02-2.18) and 2.01 (95% CI: 1.31-3.08). After adjustment for severity of obstruction, only a SGRQ in the upper tertile was associated with mortality (HR: 1.86; 95% CI: 1.14-3.02). In elderly outpatients with mild-moderate COPD, a disease-specific health status index seems to be a better predictor of death compared to a MDA.

    Peripheral artery disease (PAD) is associated with poor health status (symptoms, functioning, quality of life (QOL)). Whether sex differences exist in PAD-specific health status is unknown. In patients presenting to a specialty clinic with new-onset or recent exacerbation of PAD, we examined sex differences as assessed by the Peripheral Artery Questionnaire (PAQ). The Patient-centered Outcomes Related to TReatment Practices in Peripheral Arterial Disease: Investigating Trajectories (PORTRAIT) study is a multicenter, international prospective study of patients with new or worsening PAD symptoms. Baseline characteristics and mean PAQ scores were compared among women ( n=481) and men ( n=793) before they underwent treatment. The independent association of sex with health status was assessed with multivariable linear regression. As compared with men, women were less often Caucasian, married and employed, and more often lacking health insurance, living alone (36.2% vs 23.6%, pPAQ scores on all domains (physical functioning adjusted mean difference of -8.40, p<0.001; social functioning adjusted mean difference of -6.8, p<0.001; QOL adjusted mean difference of -6.7, p<0.001), although no differences were observed in treatment satisfaction (adjusted mean difference -0.20, p=0.904). Despite similar ABIs, women presenting with symptoms of PAD had poorer PAD-specific functioning as compared with men, impacting all major health status domains, independent of socio-economic and clinical characteristics.

    Thyroid disorders are associated with a wide variety of skin disorders that respond to treatment of hormone imbalance in most cases and thus are of vital importance to dermatologists. This study aimed to evaluate skin findings associated with autoimmune and nonautoimmune thyroid disease with respect to thyroid functional status and healthy controls. A total of 300 consecutive patients with either autoimmune (n = 173) or nonautoimmune (n = 127) thyroid disease and 100 healthy control subjects were included in this cross-sectional study. Data on patient demographics, thyroid function tests, and skin findings were recorded for patient and control groups. Compared to control subjects, patients had higher proportions in populations with alopecia (P respect to controls, autoimmune etiology, and thyroid functional status.

    Weight loss is frequently observed in patients with Alzheimer's disease (AD); however, the underlying mechanisms are not well understood. To clarify the associations between nutritional status and AD-related brain changes using Pittsburgh Compound-B (PiB)-PET, fluorodeoxyglucose (FDG)-PET, and structural MRI. The subjects were 34 amyloid-β (Aβ)-positive individuals with mild cognitive impairment or early AD (prodromal/early AD), and 55 Aβ-negative cognitively normal (CN) subjects who attended the Multimodal Neuroimaging for AD Diagnosis (MULNIAD) study. Nutritional status of the subjects was assessed by body mass index and waist to height ratio (waist circumference/height). The associations between nutritional status and brain changes were examined by multiple regression analysis using statistical parametric mapping. In the prodromal/early AD group, nutritional status was significantly positively correlated with regional cerebral glucose metabolism (rCGM) in the medial prefrontal cortices, while different topographical associations were seen in the CN group, suggesting these changes were AD-specific. Aβ deposition and gray matter volume were not significantly associated with nutritional status. Sub-analysis in the prodromal/early AD group demonstrated that fat mass index, but not fat-free mass index, was positively correlated with rCGM in the medial prefrontal areas. This present study provides preliminary results suggesting that hypometabolism in the medial prefrontal areas is specifically associated with AD-related weight loss, and decrease in fat mass may have a key role.

    (1)To assess the nutritional status of chronic renal insufficiency (CRI) and dialysis patients using the subjective global assessment (SGA) method. (2) To validate SGA in assessing the nutritional status of this group of patients. The nutritional status of 81 patients was evaluated using dietary recall, anthropometry, biochemical parameters and SGA. There were 51 males and 30 females. Their mean +/- SD age was 53.8 +/- 14.3 years. There were 27 patients with (CRI) on conservative management, 38 patients with end stage renal disease (ESRD) on maintenance hemodialysis (HD) and 16 patients with ESRD on continuous ambulatory peritoneal dialysis (CAPD). SGA was done using seven variables derived from medical history and physical examination. Each variable was scored from 1-7 depending on the severity. The SGA scores were correlated with the standard methods. Thirteen (48%) patients with CRI, 22 (58%) patients on HD and 8 (50%) patients on CAPD were malnourished. It was seen that the dietary protein & calorie intake and serum albumin level did not correlate well with the SGA scores. The anthropometric measures correlated with the SGA scores (Skinfolds and SGA r = 0.2, MAC and SGA r = 0.5 and MAMC and SGA r = 0.5). Malnutrition is an important complication in CRI patients and ESRD patients on dialysis. SGA is a reliable method of assessing nutritional status. Most important is the fact that it can detect the changing trend of nutritional status, which may be missed by one-time anthropometry and biochemical methods.

    Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality worldwide, and educational level seems to be an important determinant of the disease occurrence. The aim of this work was to investigate the association between education status and 10-year incidence of CVD, controlling for various socio-demographic lifestyle and clinical factors. From May 2001 to December 2002, 1514 men and 1528 women (>18 years) without any clinical evidence of CVD or any other chronic disease, at baseline, living in greater Athens area, Greece, were enrolled. In 2011-2012, the 10-year follow-up was performed in 2583 participants (15% of the participants were lost to follow-up). Incidence of fatal or non-fatal CVD was defined according to WHO-ICD-10 criteria. Education status was measured in years of schooling. The 10-year incidence of CVD was 15.7% [95% confidence intervals (CI) 14.1%-17.4%], 19.7% in men and 11.7% in women (Pgender 12 years of schooling). People in the low education group had higher prevalence of hypertension, diabetes and dyslipidaemias, were more likely to be smokers and sedentary, had less healthy dietary habits, as compared with those in the high education group. When controlling for participants' medical history, smoking, dietary and lifestyle habits, low education was no longer significantly associated with CVD, illustrating the mediating effect of clinical and behavioural factors in the link between education and disease. It was of interest that low education status interacted with alcohol drinking, enhancing the adverse effect of low education on CVD risk (relative risk 1.44, 95% CI 0.94%-2.20%), after various adjustments made. In this study, it was concluded that low educational level was associated with increased CVD risk. This was mainly explained by the intermediate association of low education with unhealthy choices that consequently worsen clinical status. © 2015 John Wiley & Sons Ltd.

    Directly disclosing a positive HIV serostatus to family members can affect psychological and disease status. Perceptions that one is in a supportive family environment may moderate these effects; however, ethnic differences may exist in the support processes of families coping with HIV. We examined the role of serostatus disclosure to parents, HIV-specific family support, and ethnicity (Latino versus non-Hispanic White) in explaining disease status (HIV Viral Load, CD4+ cell count) in a sample of men living with HIV (MLWH). Men (n=120) reported whether they had disclosed their serostatus to their mothers and fathers, rated their perceptions of HIV-specific social support received from family members, and provided morning peripheral venous blood samples to assess immune function. We also collected psychosocial and urinary neuroendocrine indicators of stress/distress as possible mediator variables. A three-way interaction emerged between serostatus disclosure to mothers, HIV-specific family support, and ethnicity in explaining both viral load and CD4+ cell count. Non-Hispanic White men who had disclosed to mothers and were receiving high family support had a lower viral load and higher CD4+ cell count, but Latino men who had disclosed to mothers and were receiving low family support had a higher viral load. These associations were not accounted for by men's medication adherence, psychological distress, or neuroendocrine hormones. Disclosure to fathers was not related to disease status. The effects of serostatus disclosure on disease status may depend, in part, on ethnic differences in the interpersonal processes of men's close family relationships.

    The aim of this study is to investigate sleep quality in patients with ankylosing spondylitis (AS) and to evaluate the relationship of the disease parameters with sleep disturbance. Eighty AS patients (60 males and 20 females) fulfilling the modified New York criteria, and 52 age- and gender-matched controls (33 males and 19 females) were enrolled in the study. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Pain was measured by visual analogue scale. The disease activity and functional status were assessed by the Bath AS disease Activity Index and the Bath AS Functional Index. The Bath AS Metrology Index was used to evaluate mobility restrictions, and the Bath AS Radiology Index was employed to evaluate the radiological damage. The psychological status and quality of life were assessed with the hospital anxiety-depression scale and AS quality of life scale. The patients with AS had significantly more unfavourable scores in the subjective sleep quality, habitual sleep efficiency domains (p sleep quality (total PSQI score) was positively correlated with increased pain, poor quality of life, higher depressed mood, higher disease activity and mobility restrictions. Pain was also an independent contributor to poorer sleep quality (p = 0.002). The sleep quality is disturbed in patients with AS. The lower quality of sleep is greatly associated with the pain, disease activity, depression, quality of life and increased limitation of mobility.

  19. Parametric binary dissection

    Binary dissection is widely used to partition non-uniform domains over parallel computers. This algorithm does not consider the perimeter, surface area, or aspect ratio of the regions being generated and can yield decompositions that have poor communication to computation ratio. Parametric Binary Dissection (PBD) is a new algorithm in which each cut is chosen to minimize load + lambda x(shape). In a 2 (or 3) dimensional problem, load is the amount of computation to be performed in a subregion and shape could refer to the perimeter (respectively surface) of that subregion. Shape is a measure of communication overhead and the parameter permits us to trade off load imbalance against communication overhead. When A is zero, the algorithm reduces to plain binary dissection. This algorithm can be used to partition graphs embedded in 2 or 3-d. Load is the number of nodes in a subregion, shape the number of edges that leave that subregion, and lambda the ratio of time to communicate over an edge to the time to compute at a node. An algorithm is presented that finds the depth d parametric dissection of an embedded graph with n vertices and e edges in O(max(n log n, de)) time, which is an improvement over the O(dn log n) time of plain binary dissection. Parallel versions of this algorithm are also presented; the best of these requires O((n/p) log(sup 3)p) time on a p processor hypercube, assuming graphs of bounded degree. How PBD is applied to 3-d unstructured meshes and yields partitions that are better than those obtained by plain dissection is described. Its application to the color image quantization problem is also discussed, in which samples in a high-resolution color space are mapped onto a lower resolution space in a way that minimizes the color error.

    2006-10-01

    Full Text Available Abstract Background Almost all societies carry responsibility towards patients who require continuous medical care at home. In many health systems the general practitioner cooperates with community based services of home care and coordinates all medical and non medical activities. In Austria the general practitioner together and in cooperation with relatives of the patient and professional organisations usually takes on this task by visiting his patients. This study was carried out to identify diseases that need home care and to describe the functional profile of home care patients in eastern Austria. Methods Cross sectional observational study with 17 GP practices participating during 2 study periods in 1997 and in 2004 in eastern Austria. Each GP identified patients requiring home care and assessed their underlying diseases and functional status by filling in a questionnaire personally after an encounter. Patients in nursing homes were excluded. Statistical tests used were t-tests, contingency tables, nonparametric Wilcoxon signed rank sum test and Fisher-combination test. Results Patients with degenerative diseases of the central nervous system (65% caused by Alzheimer's disease and cerebrovascular occlusive disease and patients with degenerative diseases of the skeletal system (53% were the largest groups among the 198 (1997 and 261 (2004 home care cases of the 11 (1997 and 13 (2004 practices. Malignant diseases in a terminal state constituted only 5% of the cases. More than two thirds of all cases were female with an average age of 80 years. Slightly more than 70% of the patients were at least partially mobile. Conclusion Home care and home visits for patients with degenerative diseases of the central nervous and skeletal system are important elements of GP's work. Further research should therefore focus on effective methods of training and rehabilitation to better the mental and physical status of patients living in their private homes.

    Some studies have suggested that overweight is associated with lower mortality, but these results may be affected by reverse causality. We analysed how body mass index (BMI) in young adulthood is associated with mortality in the general population and after the diagnoses of coronary heart disease (CHD), stroke and cancer. BMI was measured at an average age of 18 years in 734 438 Swedish men born in 1950-65. Diagnoses of CHD, stroke and cancer as well as all-cause mortality were derived from registers covering the whole population, up to 31 December 2010. The follow-up of 24.56 million person-years included 33 067 cases of mortality and 19 843 CHD, 13 578 stroke and 27 365 cancer diagnoses. Hazard ratios (HR) [with 95% confidence intervals (CI)] were estimated by the Cox proportional hazards model. Higher mortality in the whole cohort (HR = 1.26, 1.21-1.32) as well as after the diagnosis of CHD (HR = 1.33, 1.09-1.63) or cancer (HR = 1.13, 1.01-1.25) was found in moderately overweight men (BMI 25.0-27.4 kg/m(2)) as compared with normal weight men (BMI 20.1-22.4 kg/m(2)); for stroke patients the result for the same BMI categories was not statistically significant (HR = 1.17, 0.94-1.45). Mortality increased with increasing weight status and was highest in obese men (BMI >30 kg/m(2)): HR = 2.17 (2.02-2.34) for the whole cohort, 2.35 (1.81-3.05) after the diagnosis of CHD, 2.08 (1.56-2.77) after stroke and 1.68 (1.40-2.01) after cancer. Even moderate overweight in young adulthood increases all-cause mortality and mortality after the diagnosis of CHD, stroke and cancer in men. Preventing overweight in young adulthood remains as an important public health issue. © The Author 2014; all rights reserved.

    Zinc and copper are beneficial to health, growth and development and also for the prevention of cardiovascular disease (CVD) with regards to improved dietary habits as a preliminary step in CVD prevention. This study was conducted among 2-18 year old children with high family risk of premature CVD in comparison to controls. One hundred randomly selected children whose parents had premature myocardial infarction were included in this study. The controls were 100 individuals randomly selected from the case group's neighbors and matched for age, sex and socioeconomic status. A four-day food record questionnaire was used to assess zinc and copper intakes and their serum levels were determined using Flame-Atomic Absorption Spectrophotometry. The data were analyzed by SPSS/Windows V6 software, using the student's t and Mantel-Hanzel tests. Significance of differences was considered at P 0.05). Zinc deficiency was more prevalent among the case in boys than their controls (58% vs. 18%, P=0.04). This difference was not significant in girls (44% vs. 40%). The daily intake and serum of level of copper were not significantly different between the case and control groups. No case of copper efficiency was found. The mean systolic blood pressure was not significantly different between the zinc-deficient and zinc-sufficient subjects. Although the mean diastolic blood pressure of the former was higher than the latter, there was no statistically significant difference. About 23.7% of all studied sample had mild-to-moderate degree of failure to thrive, with significantly lower daily intake and serum zinc level than other subjects (5.41+-1.06 mg, 82.09+-12.74 ug/dL vs. 6.89+-2.14 mg, 99.25+-27.15 ug/dL, respectively, P<0.05). It is recommended that emphasis be placed on the consumption of food rich in zinc by children, especially those with high family risk of premature CVD. (author)

  5. Massive Black Hole Binary Evolution

    Directory of Open Access Journals (Sweden)

    Merritt David

    2005-11-01

    Full Text Available Coalescence of binary supermassive black holes (SBHs would constitute the strongest sources of gravitational waves to be observed by LISA. While the formation of binary SBHs during galaxy mergers is almost inevitable, coalescence requires that the separation between binary components first drop by a few orders of magnitude, due presumably to interaction of the binary with stars and gas in a galactic nucleus. This article reviews the observational evidence for binary SBHs and discusses how they would evolve. No completely convincing case of a bound, binary SBH has yet been found, although a handful of systems (e.g. interacting galaxies; remnants of galaxy mergers are now believed to contain two SBHs at projected separations of <~ 1kpc. N-body studies of binary evolution in gas-free galaxies have reached large enough particle numbers to reproduce the slow, “diffusive” refilling of the binary’s loss cone that is believed to characterize binary evolution in real galactic nuclei. While some of the results of these simulations - e.g. the binary hardening rate and eccentricity evolution - are strongly N-dependent, others - e.g. the “damage” inflicted by the binary on the nucleus - are not. Luminous early-type galaxies often exhibit depleted cores with masses of ~ 1-2 times the mass of their nuclear SBHs, consistent with the predictions of the binary model. Studies of the interaction of massive binaries with gas are still in their infancy, although much progress is expected in the near future. Binary coalescence has a large influence on the spins of SBHs, even for mass ratios as extreme as 10:1, and evidence of spin-flips may have been observed.

    A high number of coral colonies, Montipora spp., with progressive tissue loss were reported from the north shore of Kaua‘i by a member of the Eyes of the Reef volunteer reporting network. The disease has a distinct lesion (semi-circular pattern of tissue loss with an adjacent dark band) that was first observed in Hanalei Bay, Kaua‘i in 2004. The disease, initially termedMontipora banded tissue loss, appeared grossly similar to black band disease (BBD), which affects corals worldwide. Following the initial report, a rapid response was initiated as outlined in Hawai‘i’s rapid response contingency plan to determine outbreak status and investigate the disease. Our study identified the three dominant bacterial constituents indicative of BBD (filamentous cyanobacteria, sulfate-reducing bacteria, sulfide-oxidizing bacteria) in coral disease lesions from Kaua‘i, which provided the first evidence of BBD in the Hawaiian archipelago. A rapid survey at the alleged outbreak site found disease to affect 6-7% of the montiporids, which is higher than a prior prevalence of less than 1% measured on Kaua‘i in 2004, indicative of an epizootic. Tagged colonies with BBD had an average rate of tissue loss of 5.7 cm2/day over a two-month period. Treatment of diseased colonies with a double band of marine epoxy, mixed with chlorine powder, effectively reduced colony mortality. Within two months, treated colonies lost an average of 30% less tissue compared to untreated controls.

    This study was carried out to estimate the modification of hydration status within the first three months of renal transplantation. Fifty patients who underwent a first kidney allograft were prospectively followed for three months after renal transplantation to assess hydration status by bioimpedance spectroscopy. Two hours before the transplant procedure, 10/42 (23.8%) patients were overhydrated. Two days after surgery, 32/40 (80.0%) patients were overhydrated and at three months, 14/27 (51.9%) patients remained fluid-overloaded. Peritoneal dialysis (PD) patients had a lower hydration status (-0.60 L) than hemodialysis (HD) patients (0.70 L; p hydration status before transplantation (p = 0.031). At three months, 12/14 of the overhydrated patients had a creatinine clearance between 30 and 60 mL/min/1.73 m(2) . Patients receiving a first kidney transplant frequently have a hydration disorder. Transplantation is associated with increased hydration status, which seems to persist if DGF or SGF occurs. © 2011 John Wiley & Sons A/S.

    Iron status is a modifiable trait that has been implicated in cardiovascular disease. This study uses the Mendelian randomization technique to investigate whether there is any causal effect of iron status on risk of coronary artery disease (CAD). A 2-sample Mendelian randomization approach is used to estimate the effect of iron status on CAD risk. Three loci (rs1800562 and rs1799945 in the HFE gene and rs855791 in TMPRSS6 ) that are each associated with serum iron, transferrin saturation, ferritin, and transferrin in a pattern suggestive of an association with systemic iron status are used as instruments. SNP (single-nucleotide polymorphism)-iron status association estimates are based on a genome-wide association study meta-analysis of 48 972 individuals. SNP-CAD estimates are derived by combining the results of a genome-wide association study meta-analysis of 60 801 CAD cases and 123 504 controls with those of a meta-analysis of 63 746 CAD cases and 130 681 controls obtained from Metabochip and genome-wide association studies. Combined Mendelian randomization estimates are obtained for each marker by pooling results across the 3 instruments. We find evidence of a protective effect of higher iron status on CAD risk (iron odds ratio, 0.94 per SD unit increase; 95% confidence interval, 0.88-1.00; P =0.039; transferrin saturation odds ratio, 0.95 per SD unit increase; 95% confidence interval, 0.91-0.99; P =0.027; log-transformed ferritin odds ratio, 0.85 per SD unit increase; 95% confidence interval, 0.73-0.98; P =0.024; and transferrin odds ratio, 1.08 per SD unit increase; 95% confidence interval, 1.01-1.16; P =0.034). This Mendelian randomization study supports the hypothesis that higher iron status reduces CAD risk. These findings may highlight a therapeutic target. © 2017 American Heart Association, Inc.

    Malnutrition is a common finding in cancer patients, which can affect disease progression and survival. This review aims to critically summarize the prognostic role of nutritional status, from Body Mass Index (BMI) and weight loss to nutrition screening tools and biochemical indices, in cancer patients. According to the currently available data, Prognostic Nutritional Index (PNI) was a significant prognostic factor of patients' survival, both in univariate and multivariate analyses. Pre-operative albumin was also correlated with worse outcomes, being an independent prognostic factor of survival in several studies. BMI was also well-studied, with contradictory results. Although, lower BMI was found to be an independent prognostic factor of shorter survival in some studies, in others it did not have an impact on survival. In this aspect, this review highlights the significant prognostic role of nutritional status in the disease progression and survival of cancer patients. Further, good-quality prospective studies are needed in order to draw precise conclusions on the prognostic role of specific nutritional assessment tools, and biochemical indices associated with the nutritional status in more cancer types, such as liver, breast and prostate cancer, and hematological malignancies.

    Full Text Available Background: Hepatitis C virus (HCV infection is one of the most frequently encountered public health problems in Egypt. It is associated with many autoimmune diseases such as rheumatoid arthritis. Aim of the work: To assess the impact of HCV infection in rheumatoid arthritis (RA Egyptian patients; its relation to disease activity, functional status and ultrasonography findings. Patients and methods: The study included 155 RA patients further classified according to the presence of concomitant HCV infection into 2 groups; rheumatoid arthritis (RA and rheumatoid arthritis/hepatitis C virus (RA/HCV groups. All patients were subjected to full history taking, thorough clinical examination, laboratory investigations, assessment of disease activity using the disease activity score 28 (DAS28 and assessment of functional status using the modified health assessment questionnaire (MHAQ. Ultrasonography (US assessment was done using the German US7 score. Results: Both DAS28 and MHAQ scores showed significant differences between both the RA and the RA/HCV groups (p < 0.001, with higher mean values observed in the RA/HCV group (5.4 ± 1.1 and 1.05 ± 0.79 respectively. Significantly higher US7 synovitis scores were found in the RA/HCV group compared to the RA group (p = 0.03. US7 synovitis tenosynovitis scores revealed significant correlations with DAS28 and US7 synovitis scores correlated with MHAQ in both groups. Conclusion: Concomitant HCV infection in RA patients had an impact on disease activity. RA patients with concomitant HCV infection (RA/HCV had higher DAS28 and MHAQ scores, with higher US7 synovitis scores compared to RA patients. US7 score is a valuable objective tool for the assessment of RA disease activity. Keywords: Rheumatoid arthritis, HCV infection, Ultrasonography, DAS28, MHAQ

    Full Text Available We review the current status of general relativistic studies for the coalescence of black hole-neutron star (BH-NS binaries. First, procedures for a solution of BH-NS binaries in quasi-equilibrium circular orbits and the numerical results, such as quasi-equilibrium sequence and mass-shedding limit, of the high-precision computation, are summarized. Then, the current status of numerical-relativity simulations for the merger of BH-NS binaries is described. We summarize our understanding for the merger and/or tidal disruption processes, the criterion for tidal disruption, the properties of the remnant formed after the tidal disruption, gravitational waveform, and gravitational-wave spectrum.

    This exploratory pilot study aimed to investigate the physical and mental disease burden of unaccompanied asylum-seeking adolescents arriving in Bielefeld, a medium-size city in Germany. A cross-sectional survey with purposive sampling of 102 unaccompanied asylum-seeking adolescents aged 12-18 years was performed. Information on general health status, selected infectious and non-communicable diseases, iron deficiency anaemia and mental illness was collected during routine check-up medical examinations upon arrival in Bielefeld, Germany. The data were analysed using descriptive statistics. The analysis revealed a complex disease burden with a high prevalence of infections (58.8%), mental illness (13.7%) and iron deficiency anaemia (17.6%) and a very low prevalence of non-communicable diseases (<2.0%). One in five of the refugees were infected with parasites. Whilst sub-Saharan Africans showed the highest prevalence of infections (86.7%), including highest prevalences of parasites (46.7%), West Asians had the highest prevalence of mental disorders (20.0%). Overall, the disease burden in females was higher. A thorough medical and psychological screening after arrival is highly recommended to reduce the individual disease burden and the risk of infection for others. This promotes good physical and mental health, which is needed for successful integration into the receiving society. Barriers to health service access for unaccompanied asylum-seeking adolescents need to be lowered to allow need-specific health care and prevention. © 2015 John Wiley & Sons Ltd.

    Africa is a continent characterized by marked ethnic, sociodemographic, and economic diversity, with profound changes in many regions over the past 2 decades. This diversity has an impact on cardiovascular disease presentation and outcomes. Within Africa and within the individual countries, one can find regions having predominantly communicable diseases such as rheumatic heart disease, tuberculous pericarditis, or cardiomyopathy and others having a marked increase in noncommunicable disease such as hypertension and hypertensive heart disease. Ischemic heart disease remains rare in most countries. Difficulties in the planning and implementation of effective health care in most African countries are compounded by a paucity of studies and a low rate of investment in research and data acquisition. The fiduciary responsibilities of companies working in Africa should include the effective and efficient use of natural resources to promote the overall health of populations. © 2016 American Heart Association, Inc.

    Oxidative stress is intimately associated with many diseases, including chronic obstructive pulmonary disease (COPD). Study objectives include a comparison of the oxidative stress, antioxidant status, and lipid profile between COPD patients and controls and evaluation of the effect of spirulina intervention on oxidative stress, antioxidant status, and lipid profile of COPD patients. 30 patients with COPD and 20 controls with no respiratory problems were selected. Global Initiative for Chronic Obstructive Lung Disease criteria were served as the basis of COPD diagnosis. The serum content of malondialdehyde (MDA), lipid hydroperoxide, glutathione (GSH), vitamin C, cholesterol, triglyceride (TG), and high density lipoprotein (HDL) was measured. The activity of superoxide dismutase (SOD), catalase (CAT), and glutathione-s-transferase (GST) was also measured. Two different doses, (500 × 2) mg and (500 × 4) mg spirulina, were given to two groups, each of which comprises 15 COPD patients. All targeted blood parameters have significant difference (P = 0.000) between COPD patients and controls except triglyceride (TG). Spirulina intake for 30 and 60 days at (500 × 2) mg dose has significantly reduced serum content of MDA, lipid hydroperoxide, and cholesterol (P = 0.000) while increasing GSH, Vit C level (P = 0.000), and the activity of SOD (P = 0.000) and GST (P = 0.038). At the same time, spirulina intake for 30 and 60 days at (500 × 4) mg dose has favorable significant effect (P = 0.000) on all targeted blood parameters except for HDL (P = 0.163).

    Full Text Available Abstract Background The association between bronchial obstruction severity and mortality in Chronic Obstructive Pulmonary Disease (COPD is well established, but it is unknown whether disease-specific health status measures and multidimensional assessment (MDA have comparable prognostic value. Methods We analyzed data coming from the Salute Respiratoria nell'Anziano (Respiratory Health in the Elderly – SaRA study, enrolling elderly people attending outpatient clinics for respiratory and non-respiratory problems. From this population we selected 449 patients with bronchial obstruction (77.3% men, mean age 73.1. We classified patients' health status using tertiles of the Saint George Respiratory Questionnaire (SGRQ and a MDA including functional (the 6' walking test, WT, cognitive (Mini-Mental State Examination, MMSE and affective status (Geriatric Depression Scale, GDS. The agreement of the classification methods was calculated using the kappa statistic, and survival associated with group membership was evaluated using survival analysis. Results Pulmonary function, expressed by the FEV1, worsened with increasing SGRQ or MDA scores. Cognitive function was not associated with the SGRQ, while physical performance and mood status were impaired only in the highest tertile of SGRQ. A poor agreement was found between the two classification systems tested (k = 0.194. Compared to people in the first tertile of SGRQ score, those in the second tertile had a sex-adjusted HR of 1.22 (0.75 – 1.98 and those in the third tertile of 2.90 (1.92 – 4.40. The corresponding figures of the MDA were 1.49 (95% CI 1.02 – 2.18 and 2.01 (95% CI: 1.31 – 3.08. After adjustment for severity of obstruction, only a SGRQ in the upper tertile was associated with mortality (HR: 1.86; 95% CI: 1.14 – 3.02. Conclusion In elderly outpatients with mild-moderate COPD, a disease-specific health status index seems to be a better predictor of death compared to a MDA.

    Magnetic binary nanofillers containing multiwall carbon nanotubes (MWCNT) and hercynite were synthesized by Chemical Vapor Deposition (CVD) on Fe/AlOOH prepared by the sol-gel method. The catalyst precursor was fired at 450 Degree-Sign C, ground and sifted through different meshes. Two powders were obtained with different particle sizes: sample A (50-75 {mu}m) and sample B (smaller than 50 {mu}m). These powders are composed of iron oxide particles widely dispersed in the non-crystalline matrix of aluminum oxide and they are not ferromagnetic. After reduction process the powders are composed of {alpha}-Fe nanoparticles inside hercynite matrix. These nanofillers are composed of hercynite containing {alpha}-Fe nanoparticles and MWCNT. The binary magnetic nanofillers were slightly ferromagnetic. The saturation magnetization of the nanofillers depended on the powder particle size. The nanofiller obtained from powder particles in the range 50-75 {mu}m showed a saturation magnetization 36% higher than the one formed from powder particles smaller than 50 {mu}m. The phenomenon is explained in terms of changes in the magnetic environment of the particles as consequence of the presence of MWCNT.

    Small vessel disease (SVD) and Alzheimer's disease (AD) are two common causes of cognitive impairment and dementia, traditionally considered as distinct processes. The relationship between radiological features suggestive of AD and SVD was explored, and the association of each of these features with cognitive status at 1 year was investigated in patients with stroke or transient ischaemic attack. Anonymized data were accessed from the Virtual International Stroke Trials Archive (VISTA). Medial temporal lobe atrophy (MTA; a marker of AD) and markers of SVD were rated using validated ordinal visual scales. Cognitive status was evaluated with the Mini Mental State Examination (MMSE) 1 year after the index stroke. Logistic regression models were used to investigate independent associations between (i) baseline SVD features and MTA and (ii) all baseline neuroimaging features and cognitive status 1 year post-stroke. In all, 234 patients were included, mean (±SD) age 65.7 ± 13.1 years, 145 (62%) male. Moderate to severe MTA was present in 104 (44%) patients. SVD features were independently associated with MTA (P stroke, hypertension and diabetes mellitus, MTA was the only radiological feature independently associated with cognitive impairment, defined using thresholds of MMSE ≤ 26 (odds ratio 1.94; 95% confidence interval 1.28-2.94) and MMSE ≤ 23 (odds ratio 2.31; 95% confidence interval 1.48-3.62). In patients with ischaemic cerebrovascular disease, SVD features are associated with MTA, which is a common finding in stroke survivors. SVD and AD type neurodegeneration coexist, but the AD marker MTA, rather than SVD markers, is associated with post-stroke cognitive impairment. © 2016 EAN.

    Full Text Available Background: With regard to patients' self-reported somatic diseases some researchers transformed “don't know (DK” responses into “no” responses. The present study examines the appropriateness of this procedure. Methods: Analyses were based on the nationally representative German National Health Interview and Examination Survey (GHS, which assessed both self-reported diseases and physician-diagnosed diseases (N = 7124. Prevalence rates of persons’ DK responses and the corresponding prevalences of physicians’ diagnoses were calculated for persons with hypertension, coronary heart disease (CHD, heart failure, asthma, chronic bronchitis, thyroid disease, diabetes, cancer, gout, arthrosis, arthritis and osteoporosis. Correlates of physicians' diagnosed diseases of DK cases are reported. Results: Between 1.6% and 9.8% of the participants responded with DK to the question of whether they have the disease. In 3.7% to 29.5% of DK cases, the physicians did regard the respective disease as being present. With regard to persons who responded with DK, the probability of a physicians' diagnosis was increased in the case of increased age and a higher number of somatic comorbidities. Conclusion: The procedure of transforming DK responses into “no” answers does not appear to be recommendable.

    Research on rare diseases cannot be performed without appropriate samples from patients with such diseases. Due to the limited number of such patients, securing biosamples of sufficient quality for extensive research is a challenge and represents an important barrier to the advancement of research on rare diseases. To tackle this problem, the Rare Disease Bank (RDB) was established in 2009 at the National Institute of Biomedical Innovation (NIBIO; currently, the National Institutes of Biomedical Innovation, Health and Nutrition in Japan). Since then, the RDB has focused on three objectives: (1) emphasizing the importance of collecting biosamples from patients with rare diseases, together with appropriate clinical information, from various medical facilities nationwide; (2) maintaining strict high-quality sample management standards; and (3) sharing biosamples with research scientists across Japan for the advancement of research on rare diseases. As of August 2017, the bank has collected 4147 biosamples from patients with rare diseases, including DNA, serum, plasma, and cell samples from various university hospitals and other medical institutions across the country, and provided various research institutions with 13,686 biosample aliquots from 2850 cases. In addition, the management committee has successfully established a bank system that provides high-quality biosamples together with the results of human leukocyte antigen analysis. It is anticipated that the RDB, through the collection and sharing of biosamples with the medical research community, will enhance the understanding, prevention, and treatment of rare diseases in Japan and the world at large.

    2014-01-01

    Lung diseases remain a significant and devastating cause of morbidity and mortality worldwide. In contrast to many other major diseases, lung diseases notably chronic obstructive pulmonary diseases (COPDs), including both asthma and emphysema, are increasing in prevalence and COPD is expected to become the third leading cause of disease mortality worldwide by 2020. New therapeutic options are desperately needed. A rapidly growing number of investigations of stem cells and cell therapies in lung biology and diseases as well as in ex vivo lung bioengineering have offered exciting new avenues for advancing knowledge of lung biology as well as providing novel potential therapeutic approaches for lung diseases. These initial observations have led to a growing exploration of endothelial progenitor cells and mesenchymal stem (stromal) cells in clinical trials of pulmonary hypertension and COPD with other clinical investigations planned. Ex vivo bioengineering of the trachea, larynx, diaphragm, and the lung itself with both biosynthetic constructs as well as decellularized tissues have been used to explore engineering both airway and vascular systems of the lung. Lung is thus a ripe organ for a variety of cell therapy and regenerative medicine approaches.

    To assess the association of low socioeconomic status and risk factors for non-communicable diseases (diabetes, high alcohol intake, high blood pressure, obesity, physical inactivity, smoking) with loss of physical functioning at older ages. Multi-cohort population based study. 37 cohort studies from 24 countries in Europe, the United States, Latin America, Africa, and Asia, 1990-2017. 109 107 men and women aged 45-90 years. Physical functioning assessed using the walking speed test, a valid index of overall functional capacity. Years of functioning lost was computed as a metric to quantify the difference in walking speed between those exposed and unexposed to low socioeconomic status and risk factors. According to mixed model estimations, men aged 60 and of low socioeconomic status had the same walking speed as men aged 66.6 of high socioeconomic status (years of functioning lost 6.6 years, 95% confidence interval 5.0 to 9.4). The years of functioning lost for women were 4.6 (3.6 to 6.2). In men and women, respectively, 5.7 (4.4 to 8.1) and 5.4 (4.3 to 7.3) years of functioning were lost by age 60 due to insufficient physical activity, 5.1 (3.9 to 7.0) and 7.5 (6.1 to 9.5) due to obesity, 2.3 (1.6 to 3.4) and 3.0 (2.3 to 4.0) due to hypertension, 5.6 (4.2 to 8.0) and 6.3 (4.9 to 8.4) due to diabetes, and 3.0 (2.2 to 4.3) and 0.7 (0.1 to 1.5) due to tobacco use. In analyses restricted to high income countries, the number of years of functioning lost attributable to low socioeconomic status by age 60 was 8.0 (5.7 to 13.1) for men and 5.4 (4.0 to 8.0) for women, whereas in low and middle income countries it was 2.6 (0.2 to 6.8) for men and 2.7 (1.0 to 5.5) for women. Within high income countries, the number of years of functioning lost attributable to low socioeconomic status by age 60 was greater in the United States than in Europe. Physical functioning continued to decline as a function of unfavourable risk factors between ages 60 and 85. Years of functioning

    The morbidity of 1557 grandchildren of subjects occupationally exposed to chronic radiation were analyzed. Three groups were singled out. Group 1 consisted of children whose grandfathers were exposed, group 2 of children grandmothers were exposed and group 3 of children whose both grandparent were exposed. Total morbidity level and morbidity structure for 13 classes of diseases and 60 nosological entities was assessed. The study showed that disease incidence in general, structure by disease and individual nosological entities, the share of frequently falling ill children, and health index in the test group corresponded to those in controls. Reliable differences were observed only for respiratory diseases, at the expense of acute respiratory diseases, which were frequent during the second-third years of life in children whose both grandparents were occupationally exposed to radiation [ru

    Periodontitis is a serious disease that affects up to 50% of an adult population. It is a chronic condition involving inflammation of the periodontal ligament and associated tissues leading to eventual tooth loss. Some evidence suggests that trace metals, especially zinc and copper, may be involved in the onset and severity of periodontitis. Thus we have used synchrotron X-ray fluorescence imaging on cross sections of diseased and healthy teeth using a microbeam to explore the distribution of trace metals in cementum and adhering plaque. The comparison between diseased and healthy teeth indicates that there are elevated levels of zinc, copper and nickel in diseased teeth as opposed to healthy teeth. This preliminary correlation between elevated levels of trace metals in the cementum and plaque of diseased teeth suggests that metals may play a role in the progress of periodontitis.

    To assess the clinical application value of iodine metabolism biomarkers in assessing iodine nutrition status in surgically treated patients with thyroid disease. Blood,morning urine and 24-hour urine samples were collected in 31 healthy volunteers and in 30 surgically treated patients with thyroid disease before and after surgery. Iodine concentration was analyzed by inductively coupled plasma mass spectrometry. The iodine metabolism biomarkers including serum iodine (SI), morning urine iodine(UI), morning urine iodine/urine creatinine ratio (UI/UCr), 24-hour urine iodine (24 h UI), and 24-hour urine iodine excretion (24 h UIE) were evaluated in these two groups. In addition, the validation coincidence rate of iodine metabolism biomarkers in healthy volunteers to different reference ranges including World Health Organization, Mayo Clinic, and Quest Diagnostics were calculated. The UI/UCr ratio of pre-operative thyroid disease patients was significantly lower than that of healthy volunteers (P0.05) between these two groups. The SI, UI ,and 24 h UI in postoperative thyroid disease patients were significantly higher than those of the pre-operative patients (all Piodine metabolism biomarkers. The UI/UCr ratio may be used for iodine nutrition evaluation in surgically treated patients with thyroid disease.

  7. Contact Binary Asteroids

    2015-05-01

    Recent observations have found that some contact binaries are oriented such that the secondary impacts with the primary at a high inclination. This research investigates the evolution of how such contact binaries came to exist. This process begins with an asteroid pair, where the secondary lies on the Laplace plane. The Laplace plane is a plane normal to the axis about which the pole of a satellites orbit precesses, causing a near constant inclination for such an orbit. For the study of the classical Laplace plane, the secondary asteroid is in circular orbit around an oblate primary with axial tilt. This system is also orbiting the Sun. Thus, there are two perturbations on the secondarys orbit: J2 and third body Sun perturbations. The Laplace surface is defined as the group of orbits that lie on the Laplace plane at varying distances from the primary. If the secondary is very close to the primary, the inclination of the Laplace plane will be near the equator of the asteroid, while further from the primary the inclination will be similar to the asteroid-Sun plane. The secondary will lie on the Laplace plane because near the asteroid the Laplace plane is stable to large deviations in motion, causing the asteroid to come to rest in this orbit. Assuming the secondary is asymmetrical in shape and the bodys rotation is synchronous with its orbit, the secondary will experience the BYORP effect. BYORP can cause secular motion such as the semi-major axis of the secondary expanding or contracting. Assuming the secondary expands due to BYORP, the secondary will eventually reach the unstable region of the Laplace plane. The unstable region exists if the primary has an obliquity of 68.875 degrees or greater. The unstable region exists at 0.9 Laplace radius to 1.25 Laplace radius, where the Laplace radius is defined as the distance from the central body where the inclination of the Laplace plane orbit is half the obliquity. In the unstable region, the eccentricity of the orbit

    2013-03-01

    Full Text Available Galactic globular clusters are old, dense star systems typically containing 10^4 – 10^6 stars. As an old population of stars, globular clusters contain many collapsed and degenerate objects. As a dense population of stars, globular clusters are the scene of many interesting close dynamical interactions between stars. These dynamical interactions can alter the evolution of individual stars and can produce tight binary systems containing one or two compact objects. In this review, we discuss theoretical models of globular cluster evolution and binary evolution, techniques for simulating this evolution that leads to relativistic binaries, and current and possible future observational evidence for this population. Our discussion of globular cluster evolution will focus on the processes that boost the production of tight binary systems and the subsequent interaction of these binaries that can alter the properties of both bodies and can lead to exotic objects. Direct N-body integrations and Fokker–Planck simulations of the evolution of globular clusters that incorporate tidal interactions and lead to predictions of relativistic binary populations are also discussed. We discuss the current observational evidence for cataclysmic variables, millisecond pulsars, and low-mass X-ray binaries as well as possible future detection of relativistic binaries with gravitational radiation.

    Full Text Available Background: Undernutrition frequently occurs in children under five. If not treated, it will cause acute health effects and affect on cognitive development, social, physical work capacity and productivity. Undernutrition can be accompanied by the presence of infectious disease that can worsen the children’s nutritional status. This study aimed to describe the nutritional status and infectious disease of undernutrition children under five in Jatinangor Subdistrict. Methods: A qualitative study was carried out to 7 parents and undernourished children under five, in Desa Cipacing, Jatinangor. It was conducted from April to December 2012. The inclusion criterias were undernourished children under five with a history of infectious disease in the previous year, and the parents were willing to participate in this study. Exclusion criteria were parents and/or the children who were not at home when the collection of the data was conducted.. Data collection was conducted using measurement of nutritional status, in depth interview and environmental observation. The data were presented in tables, figures and narration. Results: Three subjects with undernutrition (-3SD to -2SD and four subjects with severe undernutrition (<-3SD. Factors affecting poor nutritional status were weight loss, no significant weight gain, diet and eating habit, and onset of disease. Commonly occurred infectious diseases were common cold, diarrhea, fever and cough. Some factors affecting infectious diseases were family member transmission, immunization, and treatment behavior. Conclusions: Poor nutritional status and infectious diseases contribute to undernutrition in children under five.

    What is the family history of periodontal disease and the prevalence of smoking status among patients with professionally diagnosed periodontitis? Are these factors related to extent and severity of periodontitis? Over a 10-year period, referred patients from a clinic for periodontology in the Netherlands were examined in a cross-sectional study. Patients received at the intake appointment a full-mouth periodontal examination. Data regarding family history of periodontitis and smoking status were recorded. A total of 5375 adult periodontitis patients were included in this study sample with a mean age of 50 years. The prevalence of smoking was 34% and 37% of the subjects had at least one parent or sibling with periodontitis. The chance to have severe periodontitis was higher if the patient was male, smoker or had a brother with periodontitis. Being male, smoker and having a parent with periodontitis were significantly associated with a larger extent of periodontitis. Within the investigated population familial aggregation, smoking status, age and gender are factors that were related to extent and severity of adult periodontitis. © 2016 John Wiley & Sons A/S.

    The role of SLNB for in-transit (IT) melanoma is controversial. The objective of this study was to determine the rate and prognostic significance of occult nodal disease in patients undergoing surgical nodal staging for IT disease. We conducted a retrospective review of patients with IT melanoma from May 2005 through September 2014. Analysis was limited to patients with a first-time IT event who underwent surgical excision. Associations between clinicopathologic characteristics, patterns of recurrence, and survival were analyzed. A total of 261 patients treated at our center were identified and 157 met inclusion criteria, of which 135 (86%) presented with no evidence of nodal disease. At the time of surgical excision of the IT lesion, 80 (58%) clinically node-negative patients underwent observation of the nodal basin and 55 (41%) surgical nodal staging. Twenty (36%) clinically node-negative but surgically staged patients were found to have nodal disease. Distant metastasis-free survival was 70.8 months for surgically staged node-negative patients, 19.2 months for surgically staged node-positive patients, 22.8 months for those staged node-negative by clinical examination only and 4.8 months for those with clinical nodal disease (p = 0.01). The regional nodal basin was the first site of failure in 14 of 66 (21%) clinically staged patients, 5 of 50 (10%) for those surgically staged, and 6 of 16 (38%) for those with clinical nodal disease. Patients with IT disease are at high risk for occult nodal metastasis. Because clinical staging is unreliable, SLNB should be considered. For patients with IT recurrence, the status of the regional basin is strongly prognostic and stratifies patients into low-, intermediate-, and high-risk groups.

    Full Text Available Alzheimer’s disease (AD is characterized by disorders that can impair the nutrition of the patient and lead to weight loss and nutritional deficits during the course of the disease. The aim of this study was to assess the nutritional status and food intake of Brazilian patients with Alzheimer’s disease at 3 different stages of the disease. The sample consisted of 30 subjects of both genders, mean age 77 years, with probable AD. Subjects were assessed by collecting anthropometric data, the Mini Nutritional Assessment (MNA, serum albumin content, Mini Mental State Examination and 24-hour records of food and drink. Although a steady decrease in average weight was observed as the disease progressed (CDR1: 70.8±15.9 kg; CDR2: 61.4±15.7 kg; CDR3: 56.1± 8.4 kg, the differences were not significant. MNA and serum albumin both fell during the progression of the disease (p = 0.042; p = 0.047, respectively and, at the severe stage, half the patients were found to be undernourished and the other half at risk of undernutrition. According to their body mass index, 23.3% of patients were overweight. The nutritional value of the food consumed was similar across the stages of AD. In conclusion, the majority of Brazilian patients with AD in this study exhibited cognitive decline and malnutrition. However, food intake was similar among the stages of the disease, thus having no direct association with the progression of AD.

    Calcinosis is a major cause of morbidity in JDM and has previously been linked to anti-NXP2 autoantibodies, younger age at disease onset and more persistent disease activity. This study aimed to investigate the clinical associations of anti-NXP2 autoantibodies in patients with JDM stratified by age at disease onset. A total of 285 patients with samples and clinical data were recruited via the UK Juvenile Dermatomyositis Cohort and Biomarker Study. The presence of anti-NXP2 was determined by both immunoprecipitation and ELISA. Logistic regression analysis was performed to assess the age-dependent relationship between anti-NXP2 and the development of calcinosis and disease activity measures. We identified anti-NXP2 autoantibodies in 56 patients (20%). While in all patients younger age at disease onset was associated with an increased risk of calcinosis and this relationship was nearly linear, anti-NXP2 autoantibodies substantially increased the risk of calcinosis across all ages (P = 0.025) and were detectable prior to calcinosis development. Children with anti-NXP2 autoantibodies had a greater degree of weakness (median lowest ever Childhood Myositis Assessment Score 29.6 vs 42) and were less likely to be in remission at 2 years post-diagnosis. No difference in disease activity was seen 4 years post-diagnosis. Children diagnosed at a young age have a high risk of calcinosis regardless of autoantibody status. However, the presence of anti-NXP2 autoantibodies substantially increases the risk of calcinosis across all ages and is associated with disease severity. © The Author 2014.

    Full Text Available Background: Psychological profile of inflammatory bowel disease patients is not well studied in Iran. We investigated the psychological status of Iranian patients with ulcerative colitis (UC and its relationship with disease activity and quality of life (QOL. Materials and Methods: A cross-sectional study was conducted on adult UC patients. The Lichtiger Colitis Activity Index, Hospital Anxiety and Depression Scale, General Health Questionnaire-12, and WHOQOL-BREF, were completed by the patients. Results: From 120 studied patients, 35 (29.2%, 48 (40.0%, and 46 (38.3% had significant anxiety, depression, and psychological distress, respectively. Anxiety, depression, and psychological distress were strongly correlated with disease activity (r = 0.357 to 0.439, P < 0.01. Disease activity was negatively correlated with all QOL dimensions (r = −0.245 to −0.550, P < 0.01. Anxiety, depression, and psychological distress were also negatively correlated with all QOL domains (r = −0.356 to −0.789, P < 0.01. In the regression models, anxiety was independently associated with active disease (β = 4.150, P = 0.049. Furthermore, disease activity was associated with the physical health (β = −0.371, P < 0.001. For almost all of the QOL domains, depression and psychological distress were independent predictors (β = −0.296 to −0.453, P < 0.001. Conclusion: Anxiety, depression, and psychological distress are highly frequent in UC patients of our society and are strongly associated with disease activity. Depression and psychological distress are important predictors of poor QOL in these patients. Further prospective studies, as well as clinical trials, are warranted in this regard.

    Isolated hepatitis B core antibody (anti-HBc) is a common serologic finding in HIV-infected persons, but the clinical significance is uncertain. We studied HIV/hepatitis C virus (HCV)-infected women over time to determine whether the trajectory of liver disease progression is affected by isolated anti-HBc serologic status. We performed serial enhanced liver fibrosis (ELF) markers on HIV/HCV-coinfected women to assess liver disease progression trajectory over time comparing women with isolated anti-HBc to women with either negative HB serologies, anti-HBs alone, or anti-HBc and anti-HBs. ELF, a serum marker that combines direct markers of extracellular matrix remodeling and fibrosis, was performed on serum stored biannually. Women with at least 3 ELF determinations and persistent HCV RNA positivity were included. Three hundred forty-four women, including 132 with isolated anti-HBc and 212 with other serologic findings, were included. A median of 6 (interquartile range, 5-7) biannual ELF values was available for each woman, totaling 2119 visits. ELF increased over time from a median of 9.07 for women with isolated anti-HBc and 9.10 for those without isolated anti-HBc to 9.83 and 9.88, respectively, with no difference in degree of change or slope in the mixed-effects model including age, race, CD4 count, antiretroviral therapy, and drug and alcohol use. Factors independently associated with liver disease progression were older age, lower CD4, antiretroviral therapy nonuse, and Hispanic ethnicity. Isolated anti-HBc serologic status was not associated with accelerated liver disease progression over a median of 9.5 years among HIV/HCV-coinfected women.

    Pain remains the most important problem for people with rheumatoid arthritis (RA). Active inflammatory disease contributes to pain, but pain due to non-inflammatory mechanisms can confound the assessment of disease activity. We hypothesize that augmented pain processing, fibromyalgic features, poorer mental health, and patient-reported 28-joint disease activity score (DAS28) components are associated in RA. In total, 50 people with stable, long-standing RA recruited from a rheumatology outpatient clinic were assessed for pain-pressure thresholds (PPTs) at three separate sites (knee, tibia, and sternum), DAS28, fibromyalgia, and mental health status. Multivariable analysis was performed to assess the association between PPT and DAS28 components, DAS28-P (the proportion of DAS28 derived from the patient-reported components of visual analogue score and tender joint count), or fibromyalgia status. More-sensitive PPTs at sites over or distant from joints were each associated with greater reported pain, higher patient-reported DAS28 components, and poorer mental health. A high proportion of participants (48%) satisfied classification criteria for fibromyalgia, and fibromyalgia classification or characteristics were each associated with more sensitive PPTs, higher patient-reported DAS28 components, and poorer mental health. Widespread sensitivity to pressure-induced pain, a high prevalence of fibromyalgic features, higher patient-reported DAS28 components, and poorer mental health are all linked in established RA. The increased sensitivity at nonjoint sites (sternum and anterior tibia), as well as over joints, indicates that central mechanisms may contribute to pain sensitivity in RA. The contribution of patient-reported components to high DAS28 should inform decisions on disease-modifying or pain-management approaches in the treatment of RA when inflammation may be well controlled.

    The Middle East and North Africa has witnessed a dramatic transformation over the last 30 years caused by rapid urbanization and modernization and significant changes to diet and lifestyle. This review attempts to highlight recent data in regards to ischemic heart disease and its risk factors from the region. Ischemic heart disease is now the leading cause of death in the region. Age at presentation with myocardial infarction and acute coronary syndrome appears to be significantly younger than global averages. Increased rates of all major risk factors including diabetes, hypertension, hyperlipidemia, smoking, obesity, and sedentary lifestyle have been noted. Specifically, significant changes to dietary habits and growing epidemic of use of alternative tobacco products are noted. This review article highlights the growing epidemic of ischemic heart disease in the region led by dramatic increases in incidence of its risk factors. This epidemic will require a multipronged approach to address the varied issues and mitigate the growing prevalence of the disease.

    We present the first attempt to characterize the distribution of taxonomic class among the population of binary asteroids (15% of all small asteroids). For that, an analysis of 0.8-2.5{μ m} near-infrared spectra obtained with the SpeX instrument on the NASA/IRTF is presented. Taxonomic class and meteorite analog is determined for each target, increasing the sample of binary asteroids with known taxonomy by 21%. Most binary systems are bound in the S-, X-, and C- classes, followed by Q and V-types. The rate of binary systems in each taxonomic class agrees within uncertainty with the background population of small near-Earth objects and inner main belt asteroids, but for the C-types which are under-represented among binaries.

    2010-01-01

    The discovery of extrasolar planets over the past decade has had major impacts on our understanding of the formation and dynamical evolution of planetary systems. There are features and characteristics unseen in our solar system and unexplainable by the current theories of planet formation and dynamics. Among these new surprises is the discovery of planets in binary and multiple-star systems. The discovery of such "binary-planetary" systems has confronted astrodynamicists with many new challenges, and has led them to re-examine the theories of planet formation and dynamics. Among these challenges are: How are planets formed in binary star systems? What would be the notion of habitability in such systems? Under what conditions can binary star systems have habitable planets? How will volatiles necessary for life appear on such planets? This volume seeks to gather the current research in the area of planets in binary and multistar systems and to familiarize readers with its associated theoretical and observation...

    This study aimed to demonstrate that dietary intake, anthropometric indicators, and body composition in children with end-stage kidney disease differs between those on peritoneal dialysis (PD) and those on hemodialysis (HD). This was a cross-sectional and consecutive study that included 55 children and adolescents with end-stage kidney disease who were undergoing replacement therapy (22 PD patients and 33 HD patients). Two 24-hour dietary recall surveys were conducted for each patient. Anthropometric, biochemical, and body composition indicators were estimated. A Student's t-test and a Mann-Whitney U test were used for the parametric variables, whereas association tests were estimated for the nonparametric variables (i.e., χ 2 , Fisher exact test, and odds ratio). Regression models were designed to predict dietary intake on anthropometric and body composition indicators. The mid-upper arm circumference was greater on the patients undergoing HD than on the PD patients (odds ratio = 15.8 [95% confidence interval (CI): 2.9, 85.1], P nutritional status in children on PD and 28% to 60% in children on HD. Nutritional status is affected in most patients on dialysis treatment, which differs significantly among those who are undergoing PD or HD. Copyright © 2017 National Kidney Foundation, Inc.

    We investigate whether or not Gaia can specify the binary fractions of massive stellar populations in the Galactic disk through astrometric microlensing. Furthermore, we study whether or not some information about their mass distributions can be inferred via this method. In this regard, we simulate the binary astrometric microlensing events due to massive stellar populations according to the Gaia observing strategy by considering (i) stellar-mass black holes, (ii) neutron stars, (iii) white dwarfs, and (iv) main-sequence stars as microlenses. The Gaia efficiency for detecting the binary signatures in binary astrometric microlensing events is ∼10%–20%. By calculating the optical depth due to the mentioned stellar populations, the numbers of the binary astrometric microlensing events being observed with Gaia with detectable binary signatures, for the binary fraction of about 0.1, are estimated to be 6, 11, 77, and 1316, respectively. Consequently, Gaia can potentially specify the binary fractions of these massive stellar populations. However, the binary fraction of black holes measured with this method has a large uncertainty owing to a low number of the estimated events. Knowing the binary fractions in massive stellar populations helps with studying the gravitational waves. Moreover, we investigate the number of massive microlenses for which Gaia specifies masses through astrometric microlensing of single lenses toward the Galactic bulge. The resulting efficiencies of measuring the mass of mentioned populations are 9.8%, 2.9%, 1.2%, and 0.8%, respectively. The numbers of their astrometric microlensing events being observed in the Gaia era in which the lens mass can be inferred with the relative error less than 0.5 toward the Galactic bulge are estimated as 45, 34, 76, and 786, respectively. Hence, Gaia potentially gives us some information about the mass distribution of these massive stellar populations.

    To document the type, location, extent, and complications of brain metastases in patients with breast cancer and identify associations with oestrogen receptor (ER) negative and human epidermal growth factor receptor 2 (HER-2) receptor expression. Breast cancer patients with known brain metastases were included in this retrospective study, if cross-sectional imaging of the brain [computed tomography (CT)] was available to review and HER-2 and ER status was known. Two neuroradiologists, who were blinded to the receptor status, separately and for each patient, documented on a proforma the location, number, and dimensions of the deposits and the presence or absence of hydrocephalus. Adjudication was sought where there was discrepancy between the two reports. ER status, HER-2 receptor status, and patient age were also documented. The results were analysed using two-sided Fisher's exact tests with Lancaster's mid-P correction and associations were sought between the tumour characteristics and the pattern of brain disease. Sixty patients were included in the study. There was an association between young age (brain stem metastases [11 of 18 (61%) versus three of 26 (11.5%); p = 0.035], more frequent occurrence of hydrocephalus [7 of 12 (36.8%) versus three of 26 (11.5%); p = 0.049], and a higher incidence of occipital metastases [12 of 18 (66.7%) versus eight of 26 (30.8%); p = 0.029]. ER-negative HER-2-positive women are more likely to present with a larger number of lesions, more brain stem/occipital metastases, and hydrocephalus, which may predispose them to unfavourable outcomes following treatment.

    Communication is fundamental to human interaction and the development and maintenance of human relationships and is frequently affected in Parkinson's disease (PD). However, research and clinical practice have both tended to focus on impairment rather than participation aspects of communicative deficit in PD. In contrast, people with PD have reported that it is these participation aspects of communication that are of greatest concern to them rather than physical speech impairment. To systematically review the existing body of evidence regarding the association between cognitive status and/or intelligibility and everyday communication in PD. Five online databases were systematically searched in May 2015 (Medline Ovid, EMBASE, AMED, PsycINFO and CINAHL) and supplementary searches were also conducted. Two reviewers independently evaluated retrieved records for inclusion and then performed data extraction and quality assessment using standardised forms. Articles were eligible for inclusion if they were English-language original peer-reviewed research articles, book chapters or doctoral theses investigating the associations between at least one of cognitive status and level of intelligibility impairment and an everyday communication outcome in human participants with PD. 4816 unique records were identified through database searches with 16 additional records identified through supplementary searches. 41 articles were suitable for full-text screening and 15 articles (12 studies) met the eligibility criteria. 10 studies assessed the role of cognitive status and 9 found that participants with greater cognitive impairment had greater everyday communication difficulties. 4 studies assessed the role of intelligibility and all found that participants with greater intelligibility impairment had greater everyday communication difficulties, although effects were often weak and not consistent. Both cognitive status and intelligibility may be associated with everyday communicative

    Gastrointestinal symptoms (GIS) are common in patients with end-stage renal disease (ESRD) and are associated with nutritional risks resulting from low food intake. Little is known about the relationship between GIS and malnutrition in geriatric patients with ESRD. The main objective of this study was to determine the relationship between nutritional status and severity of GIS in geriatric patients on dialysis therapy. Clinically-stable geriatric patients (older than 60 years old) who were dialysis outpatients were included in this cross-sectional study. The severity of GIS was assessed using the Gastrointestinal Symptoms Questionnaire (GSQ, short version), with patients classified into three groups: mild, moderate, and severe. Nutritional status was evaluated with the Malnutrition Inflammation Score (MIS), anthropometric assessment, biochemical parameters, and bioelectrical impedance. Descriptive statistics were used and differences between groups were analyzed with ANOVA and Kruskal Wallis, with a p hemodialysis (HD) and 27 were on peritoneal dialysis (PD). No significant differences were found according to dialysis modality, presence of diabetes, or gender. Ninety percent of patients had at least one GIS. Poorer nutritional status (evaluated by MIS) was related to a higher severity of GIS. There were no significant differences with other nutritional parameters. Our study showed a high prevalence of GIS in geriatric patients. There were no differences in observed GIS values that were attributed to dialysis modality, gender, or presence of type 2 diabetes mellitus (DM2). Severe GIS values were associated with poorer nutritional status determined by MIS, however, there was no association with anthropometry, biochemical values, or bioimpedance vector analysis.

    Fetuin-A is a hepatic secretory protein that both promotes insulin resistance and inhibits arterial calcification. Previous studies have suggested that the association of fetuin-A with incident cardiovascular disease (CVD) might be modified by glycemic status. We conducted a case-cohort study of fetuin-A and incident non-fatal CVD nested in the Multi-Ethnic Study of Atherosclerosis with follow-up from 2000 to 2007. Fetuin-A concentrations were measured from baseline serum samples among 2505 randomly selected subcohort members and 142 incident cases. In weighted multivariable Cox regression models, no association was observed between fetuin-A and incident CVD in the total study population (HR per SD = 1.01; 95% CI: 0.84, 1.23). Although associations with CVD events were not statistically significant within categories of glycemic status, our results tended to support the interaction with glycemic status observed in other studies, with a positive trend restricted to participants with impaired fasting glucose or diabetes (HR per SD = 1.20; 95% CI: 0.89, 1.63) and an inverse trend among normoglycemic individuals (HR = 0.89; 95% CI: 0.69-1.13) (p-interaction = 0.04). In addition, we observed significant interaction between fasting glucose and fetuin-A when both were treated continuously in the subset of participants not using diabetes medication (p-interaction = 0.006). Our results suggest that fetuin-A is not associated with an overall risk of CVD, but support prior evidence indicating that the association might be modified by glycemic status.

  9. Disease resistance breeding in rose: current status and potential of biotechnological tools.

    2014-11-01

    The cultivated rose is a multispecies complex for which a high level of disease protection is needed due to the low tolerance of blemishes in ornamental plants. The most important fungal diseases are black spot, powdery mildew, botrytis and downy mildew. Rose rosette, a lethal viral pathogen, is emerging as a devastating disease in North America. Currently rose breeders use a recurrent phenotypic selection approach and perform selection for disease resistance for most pathogen issues in a 2-3 year field trial. Marker assisted selection could accelerate this breeding process. Thus far markers have been identified for resistance to black spot (Rdrs) and powdery mildew and with the ability of genotyping by sequencing to generate 1000s of markers our ability to identify markers useful in plant improvement should increase exponentially. Transgenic rose lines with various fungal resistance genes inserted have shown limited success and RNAi technology has potential to provide virus resistance. Roses, as do other plants, have sequences homologous to characterized R-genes in their genomes, some which have been related to specific disease resistance. With improving next generation sequencing technology, our ability to do genomic and transcriptomic studies of the resistance related genes in both the rose and the pathogens to reveal novel gene targets to develop resistant roses will accelerate. Finally, the development of designer nucleases opens up a potentially non-GMO approach to directly modify a rose's DNA to create a disease resistant rose. Although there is much potential, at present rose breeders are not using marker assisted breeding primarily because a good suite of marker/trait associations (MTA) that would ensure a path to stable disease resistance is not available. As our genomic analytical tools improve, so will our ability to identify useful genes and linked markers. Once these MTAs are available, it will be the cost savings, both in time and money, that will

    2017-01-01

    An unprecedented rise in the number of asylum seekers and refugees was seen in Europe in 2015, and it seems that numbers are not going to be reduced considerably in 2016. Several studies have tried to estimate risk of infectious diseases associated with migration but only very rarely these studies make a distinction on reason for migration. In these studies, workers, students, and refugees who have moved to a foreign country are all taken to have the same disease epidemiology. A common disease epidemiology across very different migrant groups is unlikely, so in this review of infectious diseases in asylum seekers and refugees, we describe infectious disease prevalence in various types of migrants. We identified 51 studies eligible for inclusion. The highest infectious disease prevalence in refugee and asylum seeker populations have been reported for latent tuberculosis (9-45%), active tuberculosis (up to 11%), and hepatitis B (up to 12%). The same population had low prevalence of malaria (7%) and hepatitis C (up to 5%). There have been recent case reports from European countries of cutaneous diphtheria, louse-born relapsing fever, and shigella in the asylum-seeking and refugee population. The increased risk that refugees and asylum seekers have for infection with specific diseases can largely be attributed to poor living conditions during and after migration. Even though we see high transmission in the refugee populations, there is very little risk of spread to the autochthonous population. These findings support the efforts towards creating a common European standard for the health reception and reporting of asylum seekers and refugees.

    Full Text Available Introduction This is an open uncontrolled study about effects of physical treatment on disease activity parameters of patients with rheumatoid arthritis and psoriatic arthritis. Objective The aim of the study was to establish if there was any improvement of disease activity parameters after four weeks of physical and spa treatment. METHOD We compared morning stiffness, tender and swollen joint count, body pain level and Disease Activity Score 28 (DAS-28 in patients with rheumatoid and psoriatic arthritis, and assessed the effect of physical and spa treatment on those parameters. The research encompassed 109 patients: 69 with rheumatoid arthritis (RA group and 40 with psoriatic arthritis (PA group. They were from Norway, staying for four weeks in June-September 2003. The groups served as their own controls - "one group pre-test post test" study. Disease activity measurement was made twice: at the beginning and at the end of treatment. The therapeutic set consisted of mud applications, kinesitherapy, mineral water pool and electrotherapy. Results At the beginning there was no significant difference in observed disease activity parameters between patients with rheumatoid and psoriatic arthritis (p>0.05. After four weeks of physical and spa treatment disease activity was significantly reduced in all observed parameters in both groups: morning stiffness (p<0.001 RA+PA, tender joint count (p<0.01 RA+PA, swollen joint count (p<0.01 RA; p<0.05 PA, body pain (p<0.01 RA+PA and DAS-28 score (p<0.01 RA+PA. Conclusion Physical and spa treatment, together with climatic factors in Igalo, lead to a significant reduction of disease activity parameters of patients suffering from rheumatoid arthritis and psoriatic arthritis. .

  12. Current status of understanding of the genetic etiology of coronary heart disease

    2013-01-01

    Full Text Available Coronary heart disease (CHD, synonymously known as coronary artery disease (CAD is the most predominant among the cardiovascular diseases and ranked number one in prevalence among the developing countries. CHD is a multifactorial disease involving both genetic and environmental factors and is primarily caused due to a process of progressive damage of coronary arteries called atherosclerosis. We present here a comprehensive review of molecular genetic studies conducted so far on CAD. The information was gathered through the internet using appropriate search terms for CHD/CAD. We also compiled the relevant information from the following websites: http://www.bioguo.org/CADgene/and http://www.genome.gov. Besides several Mendelian forms of the CHD, ~300 more genes have been identified in different studies through candidate gene approach. Additionally 32 more loci have been identified through genome wide association studies that include 9p21.3 as the most replicated genetic locus across the globe. Nevertheless, overall, these studies have been characterized by a relative lack of consistency in the association pattern across the populations. A fair degree of ethnic variation in the nature of association of different genetic variants with the disease has also been apparent. Pleiotropic effects of genes, existence of subclinical phenotypes and genetic heterogeneity appear to have been the limiting factors for developing a genetic risk profile test for the disease. Given the high prevalence of this disease in India, the presence of environmental triggers and genetic variation, it would be prudent to conduct multi-ethnic large-scale studies in India, representing the subcontinent as a whole-there have been a very limited number of molecular genetic studies on Indian populations.

    One might expect that a perception of obesity being a risk factor and disease, contributes to effective obesity prevention and management strategies. However, obesity rates continue to increase worldwide. The question arises whether obesity is truly perceived as a risk factor and a disease. This paper aims at describing perception of obesity as risk factor and disease among individuals seeking care, individuals not seeking care, the society, and different professionals having a role in the field of obesity. The paper is a reflection of the lecture on the topic that was given at the EASO's New Investigators United's Summer School 2016 in Portugal and the discussion with the new investigators and other senior speakers. Individual obese patients seeking help are very much aware of obesity being a risk factor and disease, but perceptions regarding obesity seem to be flawed among those who do not seek help for obesity. Also, misperceptions regarding obesity play a role at different levels, including society, different political levels, the fields of health care and social work, prevention organizations, and the food and marketing industry. The food and marketing industry has an enormous role in changing perceptions by the society and policy makers. Obesity rates will continue to increase as long as individuals, the society, and professionals at different levels have false interpretations of the severity of obesity. Severe action is needed against those who are playing a role in maintaining false perceptions of obesity as a risk factor and disease. PMID:28278496

    Millet, P

    2006-12-01

    Tropical diseases neglected by the pharmaceutical industry usually involve developing countries. Neglected diseases can now be divided into two groups. The first includes the big three infections i.e., malaria, HIV/AIDS, and tuberculosis, that present strategic and political overtones. The second group includes a host of other fatal infections including worms, trypanosomiasis, and leishmaniasis. Fundamental research on neglected diseases has been highly productive, but there has been little success in transferring research findings to a pharmaceutical industry unwilling to take the risks associated with developing new drugs on its own. However several public-private initiatives have revived hopes of developing new products with growing involvement of industries in developing countries (India and Brazil) despite the high risks associated with fluctuating demand for medicines or funding shortages. To meet the need for testing new drugs, more clinical facilities and better patient recruitment will be needed in endemic countries. Although these new efforts to control neglected diseases are encouraging, there is now a need for coordination. Clinical research in developing countries must be organized in compliance with international principles of ethics. Testing must be aimed at validating fundamental data from industrialized countries. Appropriate incentives must be given to ensure that pharmaceutical companies use research findings for new product development. In this context, the time seems ripe for the establishment of an independent laboratory for technological innovation in neglected diseases. Such a facility could not only validate scientific data but also supervise the development of clinical applications from research data.

    1. The aim of the study was to collect baseline data on welfare, biosecurity and diseases of backyard chickens kept in the Greater London Urban Area (GLUA), United Kingdom (UK). 2. A total of 65 backyard chicken flock-keepers were recruited from May to July 2010 through adverts on websites, at City farms, veterinary practices and pet feed stores and surveyed by means of a questionnaire. A total of 30 responses were suitable for analysis. 3. Information on keepers' and flocks' characteristics, housing and husbandry practices and owners' knowledge of health problems in chickens and zoonotic diseases was collected. A welfare assessment protocol was developed and the flocks assessed accordingly. 4. Results showed that chickens were generally provided with living conditions that allowed them to perform their natural behaviours. 5. Most of the flock owners did not comply with the regulations of the Department for Environment, Food and Rural Affairs (Defra) on the feeding of catering waste. 6. Disease prevention measures such as vaccination and biosecurity, including limiting the access of human visitors, wild birds and rodents to the flocks were rare. 7. A lack of avian and zoonotic disease knowledge and awareness among the owners has implications for disease control and highlights the need for improved communication between owners, authorities and veterinarians.

    Vitamin D is hypothesized to reduce risk for tooth loss via its influence on bone health, inflammation, and the immune response. The association between plasma 25-hydroxyvitamin D [25(OH)D] concentrations and prevalence and 5-year incidence of tooth loss in a cohort of postmenopausal females was examined. Participants underwent oral examinations at study baseline (1997 to 2000) and follow-up (2002 to 2005) to determine the number of missing teeth and 5-year incidence of tooth loss, respectively. At both visits, females self-reported reasons for each missing tooth. At baseline, 152 females reported no history of tooth loss, and 628 were categorized as reporting a history of tooth loss as a result of periodontal disease (n = 70) or caries (n = 558) (total n = 780). At follow-up, 96, 376, 48, and 328 females were categorized into the aforementioned categories related to tooth loss (total n = 472). Logistic regression was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for tooth loss by category of baseline 25(OH)D (nmol/L) concentrations. Models were adjusted for age, income, smoking status, frequency of dental visits, waist circumference, and recreational physical activity. P value for trend was estimated using continuous concentrations of 25(OH)D. Among females with 25(OH)D ≥50 (adequate vitamin D status) compared to periodontal disease or caries and 1.07 (95% CI = 0.62 to 1.85), P-trend = 0.11 for the incidence of tooth loss resulting from periodontal disease or caries. No statistically significant association was observed between 25(OH)D and the history or incidence of tooth loss caused by periodontal disease. An increased odds of the history of tooth loss attributable to caries was observed with increasing concentrations of 25(OH)D (P-trend = <0.05) but was not confirmed in prospective analyses. In this cohort of postmenopausal females, the data do not support an association between vitamin D status and tooth loss.

    This study aims to estimate the impact of disease activity, obesity, functional disability, and depression on lipid status, glycoregulation, and risk for coronary heart disease (CHD) in patients with rheumatoid arthritis (RA). A total of 36 patients with RA (30 women and 6 men, mean age 54.9 years, mean disease duration 7.9 years) were included in this study. We estimated the impact of age, body mass index, disease activity [assessed by DAS28 index and C-reactive protein (CRP) value], functional ability (estimated using the HAQ disability index), and depression [assessed using the Beck Depression Inventory (BDI)] on glycoregulation, lipid status, and risk for CHD in our patients. Glycoregulation was assessed by measuring insulin resistance, insulin, and glucose in blood. Lipids tested in blood included total cholesterol, HDL and LDL cholesterol, and triglycerides (TG). The 10-year risk for CHD was estimated using the Framingham risk score. Of 36 patients, 11 (30.6 %) fulfilled the criteria for metabolic syndrome (MS). Ten of 11 patients (90.1 %) with MS have a 10-year risk for CHD greater than 10 % compared to only 3 of 25 patients (12 %) without MS (p = 0.0001). Patients with high disease activity had lower HDL values than patients with mild or moderate disease activity (1.4 vs. 1.7 mmol/l, p = 0.04). Significant correlations were observed between CRP level and insulinemia (ρ = 0.57, p = 0.003), as well as CRP level and the HOMA index (ρ = 0.59, p = 0.002). The body mass index (BMI) correlated significantly with total cholesterol (r = 0.46, p = 0.02), LDL (ρ = 0.41, p = 0.04), and TG (ρ = 0.65, p Obesity was found to be an independent risk factor for increased total cholesterol, LDL cholesterol, and TG.

    Full Text Available It has been found during the research that the changes of Th1 and Th2 marker cytokine content in Graves Disease are dynamic and are directly correlated not only with the severity of autoimmune thyrotoxicosis, but also with the method of treatment used and duration of Thiamazole therapy. The beginning of autoimmune thyrotoxicosis shows the largest amounts of both pro-inflammatory (IL-1a, IL-8, IFN-γ and anti-inflammatory (IL-10 cytokines which are significantly reduced during Thiamazole therapy, with the exception of the cases of severe disease course. Thyroid resection does not result in immunologic remission either, which is confirmed by persisting high serum levels of IL-1a, IL-8, IFN-γ, IL-10 and TSH antibodies in the severe GBD group. Among the unfavorable prognostic factors for recurrent disease are high serum levels of TSH antibodies, IL-1a and IFN-γ during pre-surgery period.

    Chronic obstructive pulmonary disease (COPD) is a major global health problem. The current therapies are inadequate and have numerous adverse effects. There is an acute need of potential alternative therapies. Medicinal plants are classical and most widespread form of medication for treating various human ailments throughout the world. For COPD also, various plants are practiced in many countries. We have surveyed the literatures for the medicinal plants which are used in obstructive lung diseases such as bronchitis and emphysema. These plants were segregated into two categories. Firstly, the plants which are used for obstructive lung diseases based on various traditional recommendations only. Secondly, the plants or their formulations which have been studied grossly in COPD patients and animal models for their scientific validation. Further, we have described some known cellular and molecular factors involved in COPD and their modulation by plant-derived compounds. Certain future perspectives have also been discussed.

    Full Text Available Alteration of gut microbiota is involved in several chronic inflammatory and autoimmune diseases, including rheumatoid arthritis, and gut microbial pro-arthritogenic profiles have been hypothesized. Intestinal inflammation may be involved in spondyloarthropathies and in a subset of patients affected by Juvenile Idiopathic Arthritis (JIA, the most common chronic rheumatic disease of childhood. We compared the fecal microbiota composition of JIA patients with healthy subjects (HS, evaluating differences in microbial profiles between sub-categories of JIA, such as enthesitis-related arthritis (JIA-ERA, in which inflammation of entheses occurs, and polyarticular JIA, non-enthesitis related arthritis (JIA-nERA. Through taxon-level analysis, we discovered alteration of fecal microbiota components that could be involved in subclinical gut inflammation, and promotion of joint inflammation. We observed abundance in Ruminococcaceae in both JIA categories, reduction in Clostridiaceae and Peptostreptococcaceae in JIA-ERA, and increase in Veillonellaceae in JIA-nERA, respectively compared with HS. Among the more relevant genera, we found an increase in Clostridium cluster XIVb, involved in colitis and arthritis, in JIA-ERA patients compared with HS, and a trend of decrease in Faecalibacterium, known for anti-inflammatory properties, in JIA-nERA compared with JIA-ERA and HS. Differential abundant taxa identified JIA patients for the HLA-B27 allele, including Bilophila, Clostridium cluster XIVb, Oscillibacter and Parvimonas. Prediction analysis of metabolic functions showed that JIA-ERA metagenome was differentially enriched in bacterial functions related to cell motility and chemotaxis, suggesting selection of potential virulence traits. We also discovered differential microbial profiles and intra-group variability among active disease and remission, suggesting instability of microbial ecosystem in autoimmune diseases with respect to healthy status.

    Full Text Available Background and Objective. Oxidative stress is intimately associated with many diseases, including chronic obstructive pulmonary disease (COPD. Study objectives include a comparison of the oxidative stress, antioxidant status, and lipid profile between COPD patients and controls and evaluation of the effect of spirulina intervention on oxidative stress, antioxidant status, and lipid profile of COPD patients. Methods. 30 patients with COPD and 20 controls with no respiratory problems were selected. Global Initiative for Chronic Obstructive Lung Disease criteria were served as the basis of COPD diagnosis. The serum content of malondialdehyde (MDA, lipid hydroperoxide, glutathione (GSH, vitamin C, cholesterol, triglyceride (TG, and high density lipoprotein (HDL was measured. The activity of superoxide dismutase (SOD, catalase (CAT, and glutathione-s-transferase (GST was also measured. Two different doses, (500 × 2 mg and (500 × 4 mg spirulina, were given to two groups, each of which comprises 15 COPD patients. Results. All targeted blood parameters have significant difference (P=0.000 between COPD patients and controls except triglyceride (TG. Spirulina intake for 30 and 60 days at (500 × 2 mg dose has significantly reduced serum content of MDA, lipid hydroperoxide, and cholesterol (P=0.000 while increasing GSH, Vit C level (P=0.000, and the activity of SOD (P=0.000 and GST (P=0.038. At the same time, spirulina intake for 30 and 60 days at (500 × 4 mg dose has favorable significant effect (P=0.000 on all targeted blood parameters except for HDL (P=0.163.

    The application of artificial intelligence in the diagnosis of obstructive lung diseases is an exciting phenomenon. Artificial intelligence algorithms work by finding patterns in data obtained from diagnostic tests, which can be used to predict clinical outcomes or to detect obstructive phenotypes. The purpose of this review is to describe the latest trends and to discuss the future potential of artificial intelligence in the diagnosis of obstructive lung diseases. Machine learning has been successfully used in automated interpretation of pulmonary function tests for differential diagnosis of obstructive lung diseases. Deep learning models such as convolutional neural network are state-of-the art for obstructive pattern recognition in computed tomography. Machine learning has also been applied in other diagnostic approaches such as forced oscillation test, breath analysis, lung sound analysis and telemedicine with promising results in small-scale studies. Overall, the application of artificial intelligence has produced encouraging results in the diagnosis of obstructive lung diseases. However, large-scale studies are still required to validate current findings and to boost its adoption by the medical community.

    Descriptive cross-sectional study. To determine the prevalence of vitamin D deficiency in patients with degenerative diseases of the spine about to undergo spinal surgery and the relations between such deficiency and potential risk factors. Vitamin D has a major role in musculoskeletal system health maintenance. Recently, studies on degenerative diseases of the spine have shown a high prevalence of vitamin D deficiency in patients undergoing spine surgery. Serum levels of 25(OH)D were determined by an electrochemiluminescence detection assay. The other variables were determined through relevant questionnaires, and the data was analyzed through analysis of variance, t -test, chi-square and multivariate logistic regression analysis. A total of 110 patients were enrolled in the study. The mean serum level of 25(OH)D was 27.45±18.75 ng/mL, and 44.5% of patients showed vitamin D deficiency (25(OH)Ddegenerative diseases of the spine. On the other hand, the conventional risk factors such as old age or female sex alone did not seem to be sufficient in determining the likelihood of deficiency. Thus, it is recommended that vitamin D deficiency prevention strategies comprise a broader spectrum of the population through which such degenerative diseases and their consequences may be prevented or delayed.

    2014-01-01

    The paper presents the most recent reports on celiac disease, especially its manifestations within the oral cavity. Particular attention should be paid to typical dental enamel defects with a various degree of advancement: discolorations, horizontal groves and pits, and even significant structural destruction causing the change of the dental crown. Symmetric location of defects within all dentition sections, and within the same anatomic groups of teeth (the most frequently: incisors and first permanent molars), is specific for celiac disease. The changes described above may be the only manifestation of celiac disease; therefore, in the case of their occurrence further studies towards gluten intolerance are recommended even when other symptoms are not present. In celiac patients, recurrent aphthae and other disorders of the oral mucosa such as ulceration, erythema, atrophic glossitis, as well as dryness and a burning sensation (particularly of the tongue) may be present, which may be caused by malnutrition. Delayed tooth eruption may also be a consequence of alimentary deficiency in celiac disease.

    2001-10-01

    Alzheimer's disease (AD) is a genetically complex and heterogeneous disorder. Recent estimates suggest that possibly over 70% of the genetic variance for the disease remains unaccounted for by apolipoprotein E (APOE) and the three known early-onset AD genes (APP, PSEN1, PSEN2). Specifically, one recent segregation analysis predicted the existence of up to four additional susceptibility genes having a similar or greater effect than APOE. However, most of the nearly three dozen putative AD loci proposed to date have only been inconsistently replicated in follow up analyses and more studies are necessary to distinguish false-positive findings from genuine signals. Novel AD genes will not only provide valuable clues for the development of novel therapeutic approaches, but will also allow the development of new genetic risk-profiling strategies that are an essential prerequisite for early prediction/prevention of this devastating disease. In this review, we will present a brief overview of analytic tools in complex disease genetics, as well as a summary of recent linkage and association findings indicating the existence of novel late-onset AD genes on chromosomes 12, 10, and 9.

    In Huntington's disease, 60% of the variance in onset age is not explained by the huntingtin gene mutation. Huntington's disease onset was earlier in caffeine users. The objective of this study was to assess the relationship of lifestyle factors with motor phenoconversion among persons at risk for Huntington's disease. The associations of motor phenoconversion and exposure to selected lifestyle and health factors were examined using Cox proportional hazards analyses adjusted for age, gender, and repeat length. Of 247 participants, 36 (14.6%) phenoconverted. Mean follow-up was 4.2 years. Greater caffeinated soda use was associated with an increased hazard of phenoconversion: moderate use hazard ratio 2.26 (95% confidence interval 0.59-8.71), high use hazard ratio 4.05 (95% confidence interval 1.18-13.96). Huntington's disease onset was earlier among consumers of caffeinated soda, but not other caffeinated beverages. This finding may be spurious or not related to caffeine. © 2018 International Parkinson and Movement Disorder Society. © 2018 International Parkinson and Movement Disorder Society.

    A six-months sports programme had been implemented to analyze the impact of movement, play and sports on the physical situation of persons having rheumatism, their mental well-being and attitudes towards sporting activities. 41 patients participated in the programme, attending training sessions in a fitness studio once a week. The sports programme contained general endurance training, functional and strengthening exercises, elements of gymnastics and play, as well as relaxation techniques. The following assessment tools were used: Measurement of Patient Outcome (MOPO) scales, sports questionnaire, and the STEP test. It was found that participants' health status, both physical and mental, had been influenced in a positive manner, with proof being provided of reduced levels of anxiety, depression, and pain. Moreover, attitudinal changes toward sports appear to have resulted, suggesting persistent motivation to engage in sporting activity.

    2014-02-01

    In this work, we address the problem of content identification. We consider content identification as a special case of multiclass classification. The conventional approach towards identification is based on content fingerprinting where a short binary content description known as a fingerprint is extracted from the content. We propose an alternative solution based on elements of machine learning theory and digital communications. Similar to binary content fingerprinting, binary content representation is generated based on a set of trained binary classifiers. We consider several training/encoding strategies and demonstrate that the proposed system can achieve the upper theoretical performance limits of content identification. The experimental results were carried out both on a synthetic dataset with different parameters and the FAMOS dataset of microstructures from consumer packages.

    Binary coherent state alphabets can be represented in a two-dimensional Hilbert space. We capitalize this formal connection between the otherwise distinct domains of qubits and continuous variable states to map binary phase-shift keyed coherent states onto the Bloch sphere and to derive their quantum-optimal clones. We analyze the Wigner function and the cumulants of the clones, and we conclude that optimal cloning of binary coherent states requires a nonlinearity above second order. We propose several practical and near-optimal cloning schemes and compare their cloning fidelity to the optimal cloner.

    2011-12-01

    Full Text Available Abstract Background Caused by Mycobacterium leprae (ML, leprosy presents a strong immune-inflammatory component, whose status dictates both the clinical form of the disease and the occurrence of reactional episodes. Evidence has shown that, during the immune-inflammatory response to infection, the growth hormone/insulin-like growth factor-I (GH/IGF-I plays a prominent regulatory role. However, in leprosy, little, if anything, is known about the interaction between the immune and neuroendocrine systems. Methods In the present retrospective study, we measured the serum levels of IGF-I and IGBP-3, its major binding protein. These measurements were taken at diagnosis in nonreactional borderline tuberculoid (NR BT, borderline lepromatous (NR BL, and lepromatous (NR LL leprosy patients in addition to healthy controls (HC. LL and BL patients who developed reaction during the course of the disease were also included in the study. The serum levels of IGF-I, IGFBP-3 and tumor necrosis factor-alpha (TNF-α were evaluated at diagnosis and during development of reversal (RR or erythema nodosum leprosum (ENL reaction by the solid phase, enzyme-labeled, chemiluminescent-immunometric method. Results The circulating IGF-I/IGFBP-3 levels showed significant differences according to disease status and occurrence of reactional episodes. At the time of leprosy diagnosis, significantly lower levels of circulating IGF-I/IGFBP-3 were found in NR BL and NR LL patients in contrast to NR BT patients and HCs. However, after treatment, serum IGF-I levels in BL/LL patients returned to normal. Notably, the levels of circulating IGF-I at diagnosis were low in 75% of patients who did not undergo ENL during treatment (NR LL patients in opposition to the normal levels observed in those who suffered ENL during treatment (R LL patients. Nonetheless, during ENL episodes, the levels observed in RLL sera tended to decrease, attaining similar levels to those found in NR LL patients

    Weight loss is frequently observed in patients with Alzheimer's disease (AD), as observed in clinical practice and reported in the literature. However, information on the evolution of nutritional status and its impact on the prognosis of AD is still scarce. Our aim was to determine the impact of nutritional status on the evolution of AD and on the response to treatment with acetylcholinesterase inhibitors (AChEI) by prospective one-year follow-up of AD patients living at home. We studied a cohort of 523 patients with Alzheimer's disease referred from 1994 to 2002 to an Alzheimer centre. After diagnosis, they were followed for one year in a prospective observational study in clinical practice. At entry and every 6 months, patients underwent standardised neurocognitive and geriatric evaluation (MMSE, ADAS-cog, IADL, MNA, caregiver burden). These evaluations were accompanied by complete clinical examination, standard paraclinical investigations and recording of treatment received. Of our patients, 25.8% presented at inclusion a risk of undernutrition with an MNA score of 23.5 or less. During follow-up, the number of patients with rapid loss on the MMSE (3 points or more in one year) was higher in subjects who presented a risk of undernutrition at inclusion (53.6%) than in well-nourished subjects (43.2%) (P = 0.07). Similarly, increased dependence at one year was more frequent in subjects at risk of undernutrition at inclusion (57.7% versus 44.4%, P = 0.0219). The beneficial effect of AChEI treatment on cognitive function was not influenced by initial nutritional status; on the contrary, among the subjects at risk of undernutrition at inclusion, the risk of rapid loss on the MMSE in one year was decreased in subjects treated during follow-up compared with untreated subjects (43.9% versus 73.1% ; OR = 0.29; 95% CI = 0.10-0.83; P = 0.0219). This relationship was not found in subjects whose initial MNA score was greater than 23.5. Our work indicates that AD patients

    Socioeconomic status (SES) is importantly associated with cardiovascular morbidity and mortality, but no information exists on the relationship between SES and progression of atherosclerotic vascular disease. We investigated the association between education and income and the 4-year progression of carotid atherosclerosis in a population-based sample of Finnish men. Data from the Kuopio Ischemic Heart Disease Risk Factor Study were used to estimate changes in maximum and mean intima-media thickness (IMT) and maximum plaque height across levels of SES in 1022 men. Associations between SES and atherosclerotic progression were examined in relation to risk factors and stratified by baseline levels of atherosclerosis and prevalent ischemic heart disease (IHD). There were significant, inverse, graded relationships between levels of education and income for all three progression measures, which were largely unaffected by risk factor adjustment. For education, the age- and baseline IMT-adjusted maximum progression for those with primary schooling or less was 0.28 mm and for those who graduated from high school, 0.24 mm (P = .05). Compared with the lowest SES group, men with the highest SES had 14% to 29% less atherosclerotic progression, depending on the measure used. Associations of the same magnitude were evident in subgroups without advanced baseline IMT and in men who were free of IHD. These results show that men with poor education and low income have significantly greater progression of carotid atherosclerosis than men with more advantages. The findings strengthen the contention that SES plays a significant role early in the atherosclerotic disease process and that reducing the burden of atherosclerotic vascular disease associated with lower SES will require approaches that focus on all stages of the life course.

    This report contains statistical interpretations of blood- and serum-levels of zinc, magnesium and copper, including dates of 380 patients with alopecia areata, alopecia androgenetica, psoriasis vulgaris, vitiligo, rosacea, venous ulcer and atopic eczema, compared with 31 healthy people. Significant low blood-levels of zinc were only proved in vitiligo, significant high levels were found in all patients of the psoriasis group. The serum-level of zinc was low in diagnoses as well as the blood-levels of copper. Blood- and serum-levels of magnesium were similar in all dermatological diseases; all of them were increased in comparison with the control group (significance level p = 0.05). Furthermore there were linear dependences of the variables, due to the examined diseases. It is of some interest that we could not prove a normal distribution of blood- and serum-levels of magnesium as often described in literature.

    Degenerative diseases of the brain have proven challenging to treat, let alone cure. One of the treatment options is the use of stem cell therapy, which has been under investigation for several years. However, treatment with stem cells comes with a number of drawbacks, for instance the source of these cells. Currently, a number of options are tested to produce stem cells, although the main issues of quantity and ethics remain for most of them. Over recent years, the potential of induced pluripotent stem cells (iPSCs) has been widely investigated and these cells seem promising for production of numerous different tissues both in vitro and in vivo. One of the major advantages of iPSCs is that they can be made autologous and can provide a sufficient quantity of cells by culturing, making the use of other stem cell sources unnecessary. As the first descriptions of iPSC production with the transcription factors Sox2, Klf4, Oct4 and C-Myc, called the Yamanaka factors, a variety of methods has been developed to convert somatic cells from all germ layers to pluripotent stem cells. Improvement of these methods is necessary to increase the efficiency of reprogramming, the quality of pluripotency and the safety of these cells before use in human trials. This review focusses on the current accomplishments and remaining challenges in the production and use of iPSCs for treatment of neurodegenerative diseases of the brain such as Alzheimer's disease and Parkinson's disease. © 2016 John Wiley & Sons A/S.

    Iron deficiency is important in the pathogenesis of restless legs syndrome (RLS), and serum ferritin measurement, using a cutoff of 45-50ng\\/ml, is widely recommended as the optimal screening test for iron deficiency in RLS. Serum ferritin often increases with inflammation, and a higher cutoff may be better in those with acute and chronic inflammatory conditions, including those with chronic kidney disease (CKD).

    The aim of the present study was to identify disease parameters, defensive styles and ego strength measurements associated with various forms of psychiatric complications in patients with multiple sclerosis (MS). Seventy-nine patients with MS participated in the study and 158 healthy subjects matched for age and sex served as controls. A wide range of clinical information was collected and the following self-report instruments were used: General Health Questionnaire, Symptom Distress Check List, Defense Style Questionnaire, MMPI Ego Strength Scale and Hostility and Direction of Hostility Questionnaire. The odds of being assessed with a psychiatric diagnosis upon interview were 6.7 times greater among patients compared to controls and 9.3 times greater among patients with recent-onset MS compared to patients with long-term disease. Psychiatric complications of MS were closely associated with age of the disease onset and the degree of disability due to MS. Additionally, higher rates of introverted hostility, adoption of maladaptive ego defenses and weakened ego strength were also closely associated with several forms of psychological distress, especially depressive symptoms. MS patients experience elevated symptoms of psychological distress, especially depressive symptoms, which are most closely associated with disease parameters. However, the crucial role of various personality traits such as ego defenses and hostility features in the psychiatric symptom formation also appear to contribute to the development of depressive symptoms. Clinicians involved in the clinical management of patients with MS should identify and modify treatment if these specific personality markers that indicate the exhaustion of the patient's resources to cope with the physical and psychological stress of the illness are present.

    To determine the prevalence and clinical characteristics of psoriatic arthritis mutilans (PAM) in the Nordic countries. Patients with putative PAM aged ≥ 18 years were recruited. Fifty-nine patients were included after clinical examination. The prevalence of PAM in the adult Nordic population was estimated to be 3.69 per million inhabitants [95% confidence interval (CI) 2.75-4.63]. The female to male ratio was close to 1:1. The mean age of skin disease onset was 25 years and the mean age of onset of joint disease was 30 years. The onset of skin disease was 2 years earlier among female patients. At inclusion, the mean duration of arthritis was 27 ± 11 years for male patients and 33 ± 11 years for female patients. PAM was most frequently seen in the distal interphalangeal (DIP) joints of the toes, followed by the IP joint of the thumb and the DIP joint of the little finger on the left hand. Female and male patients had similar numbers of painful and swollen joints. Enthesitis was found in 19 patients (32%), while 38 patients (64%) had a history of dactylitis. Twenty-three of these 38 patients (61%) had a history of dactylitis in the same finger/toe as they had PAM. At the time of inclusion, 45% of the patients were found to have clear or almost clear skin. PAM in the Nordic countries has a low prevalence, with only three to five cases per million inhabitants. The majority of the patients present with mild skin disease.

    Obesity, a complex disease determined both by genetic and environmental factors, is strongly associated with NAFLD, and has been demonstrated to have a negative impact on HCV and other chronic liver diseases (CLD). This study assessed the association between type and location of food sources and chronic liver disease (CLD) using Geographic Information Systems (GIS). CLD patients completed surveys [267 subjects, 56.5% female, age 55.8 ± 12.0, type of CLD: 36.5% hepatitis C (HCV), 19.9% hepatitis B (HBV), 19.9% non-alcoholic fatty liver disease (NAFLD); primary food source (PFS): 80.8% grocery store, secondary: 26.2% bulk food store, tertiary: 20.5% restaurants; fresh food (FF): 83%, pre-packaged (PP) 8.7%, already prepared (AP) 8.3%]. FF consumers had significantly fewer UEH servings/month (p = 0.030) and lived further away from convenience stores (1.69 vs. 0.95 km, p = 0.0001). Stepwise regression reveals the lowest FF consumers were NAFLD patients, subjects with UEH or restaurants and ethnic food stores as their PFS (R = 0.557, p = 0.0001). Eating already-packaged foods and utilizing restaurants or ethnic food stores as the PFS positively correlated with NAFLD (R = 0.546, p = 0.0001). Environmental food source measures, including type and density, should be included when examining areas hyper-saturated with a variety of food options. In hyper-saturated food environments, NAFLD patients consume more prepared food and less FF. CLD patients with UEH also eat significantly more prepared food and frequent restaurants and ethnic food stores as their PFS.

    Full Text Available The oral cavity has sometimes been described as a mirror that reflects a person's health. Systemic diseases such as diabetes or vitamin deficiency may be seen as alterations in the oral mucosa. A variety of external factors cause changes in the oral mucosa, thus altering mucosal structure and function, and promoting oral pathologies (most frequently bacterial, fungal and viral infections. Little is known, however, about immune surveillance mechanisms that involve the oral mucosa.

    The dietary intake of patients with nonalcoholic fatty liver disease (NAFLD) is generally characterized by high levels of carbohydrate, fat, and/or cholesterol, and these dietary patterns influence hepatic lipid metabolism in the patients. Therefore, careful investigation of dietary habits could lead to better nutrition therapy in NAFLD patients. The main treatment for chronic hepatitis C (CHC) is interferon-based antiviral therapy, which often causes a decrease in appetite and energy intake;...

    Full Text Available Behcet’s Disease (BD is a multisystem chronic inflammatory disease. The pathology is believed to involve both genetic susceptibility and environmental factors. Hypomethylation leading to activation of interspersed repetitive sequences (IRSs such as LINE-1 and Alu contributes to the pathologies of autoimmune diseases and cancer. Herein, the epigenetic changes of IRSs in BD were evaluated using combined bisulfite restriction analysis-interspersed repetitive sequences (COBRA-IRS. DNA from neutrophils and peripheral blood mononuclear cells (PBMCs of BD patients with ocular involvement that were in active or inactive states and healthy controls were used to analyze LINE-1 and Alu methylation levels. For Alu sequences, significant differences were observed in the frequency of CuCu alleles between PBMCs of patients and controls (p=0.03, and between inactive patients and controls (p=0.03. For neutrophils, the frequency of CuCu was significantly higher between patients and controls (p=0.006 and between inactive patients and controls (p=0.002. The partial methylation (CuCm+CmCu frequencies of Alu between inactive patients and control samples also differed (p=0.02. No statistically significant differences for LINE-1 were detected. Thus, changes in the methylation level of IRS elements might contribute to the pathogenesis of BD. The role of Alu transcripts in BD should be investigated further.

  15. Nutritional status and eating disorders: neglected risks factor for nontuberculous mycobacterial lung disease?

    2012-01-01

    Nontuberculous mycobacterial lung disease (NTMLD) in immunocompetent patients is an increasingly important epidemiologic concern. However, risk factors associated with susceptibility to NTMLD are not completely known. A prevalence of NTMLD appears to be rising, mainly in some populations such as middle-aged or elderly thin women, (a group including those with Lady Windermere syndrome) with neither remarkable history of respiratory disease nor smoking habit. Right middle lobe (RML) and lingula are often involved. Various predisposing factors and genetic defects have been described as possible causes of development of NTMLD, namely: voluntary suppression of cough, RML anatomical factors, menopause and mutations in cystic fibrosis transmembrane conductance regulator (CFTR). Malnutrition is also an important and common risk factor associated with other mycobacterial disease like tuberculosis (TB) and its probable association with NTMLD as have been pointed out for some authors. However, a real description of all nutritional aspects and eating habits of patients prior to NTMLD diagnosis is lacking. We hypothesized that malnutrition and eating disorders like anorexia nervosa could be risk factors that may promoting NTMLD. From a clinical viewpoint, if this hypothesis proves to be correct, eating habits and nutritional aspects should be taken into account in the diagnosis process of suspected NTMLD, since they are easily identifiable and treatable conditions.

    Studies of the roles of microbial communities in the development of inflammatory bowel disease (IBD) have reached an important milestone. A decade of genome-wide association studies and other genetic analyses have linked IBD with loci that implicate an aberrant immune response to the intestinal microbiota. More recently, profiling studies of the intestinal microbiome have associated the pathogenesis of IBD with characteristic shifts in the composition of the intestinal microbiota, reinforcing the view that IBD results from altered interactions between intestinal microbes and the mucosal immune system. Enhanced technologies can increase our understanding of the interactions between the host and its resident microbiota and their respective roles in IBD from both a large-scale pathway view and at the metabolic level. We review important microbiome studies of patients with IBD and describe what we have learned about the mechanisms of intestinal microbiota dysfunction. We describe the recent progress in microbiome research from exploratory 16S-based studies, reporting associations of specific organisms with a disease, to more recent studies that have taken a more nuanced view, addressing the function of the microbiota by metagenomic and metabolomic methods. Finally, we propose study designs and methodologies for future investigations of the microbiome in patients with inflammatory gut and autoimmune diseases in general. Copyright © 2014 AGA Institute.

  17. Status of adolescent pelvic inflammatory disease management in the United States.

    2013-10-01

    Pelvic inflammatory disease (PID) is a common and serious reproductive health disorder and disease rates remain unacceptably high among adolescent girls and young adult women in the United States. Despite data demonstrating that women experience major adverse health outcomes after PID, national recommendations for management of adolescents have become increasingly less cautious in an era of cost-containment. In this review, we take an alternative look at published data on adolescents with PID to frame the next steps for optimizing management for this vulnerable population. Several findings emerge from review of the literature. First, there is limited evidence to guide the best practice strategies for adolescents with PID due to low enrolment of early and middle adolescents in national trials. Second, adolescents and adult women in the United States receive suboptimal treatment regimens per Centers for Disease Control and Prevention (CDC) standards. Third, available evidence suggests that adolescents are at an increased risk for poor adherence to CDC recommendations for self-care, reacquisition of sexually transmitted infections (STIs) and PID, and subsequent adverse reproductive health outcomes. Efforts to develop and integrate adolescent-focused, evidence-based strategies for PID management and prevention of subsequent STIs and recurrent PID are warranted.

    Full Text Available The relationship between congenital heart disease (CHD and growth retardation is well documented. We investigated the growth condition of Iranian children with several types of congenital heart disease (CHD and compared it with worldwide researches. Growth condition was investigated in 469 patients with important CHD aged from 1 month to 18 years. The patients were divided into two groups; infants (aged 12 months or less, and children (1-18 yrs of age. Children with hemodynamically unimportant small VSDs or small ASDs were not studied. Other exclusion criteria were prematurity, known genetic disorders and neurologic disease affecting growthd. All patients' cardiac diagnoses were made on the basis of clinical and laboratory examinations; including electrocardiography, echocardiography, cardiac catheterization, and angiography. Body weight and height of all patients were measured using conventional methods and compared with standard growth charts. In all patients body weights and heights were significantly lower than normal population. This difference was greater in the weight of female children. Other risk factors for growth failure were large left-to-right intracardiac shunts, pulmonary hypertension and cyanosis. Iranian children with CHD have growth failure somewhat different from other countries. Lower body weights of cyanotic patients and female children indicated that these patients need more nutritional and psychosocial attention.

    Brain tissue (hippocampus and cerebral cortex) from Alzheimer's disease and control individuals sampled from Eastern Canada and the United Kingdom were analyzed for Ag, Al, As, B, Br, Ca, Cd, Co, Cr, Cs, Cu, Fe, Hg, I, K, La, Mg, Mn, Mo, Ni, Rb, S, Sb, Sc, Se, Si, Sn, Sr, Ti, V and Zn. Neutron activation analysis (thermal and prompt gamma-ray) methods were used. Very highly significant differences (S**: probability less than 0.005) for both study areas were shown between Alzheimer's disease (AD) and control (C) individuals: AD>C for Al, Br, Ca and S, and AD< C for Se, V and Zn. Aluminium content of brain tissue ranged form 3.605 to 21.738 μg/g d.w. (AD) and 0.379 to 4.768 μg/g d.w. (C). No statistical evidence of aluminium accumulation with age was noted. Possible zinc deficiency (especially for hippocampal tissue), was observed with zinc ranges of 31.42 to 57.91 μg/g d.w. (AD) and 37.31 to 87.10 μg/g d.w. (C), for Alzheimer's disease patients.

    This study examined the relationships among stressors, social support, depressive symptoms and the general health status of Taiwanese caregivers of individuals with stroke or Alzheimer's disease. Caring for a disabled or cognitively impaired person can be extremely stressful and often has adverse effects on caregivers' health. While research on caregiving in Taiwan has examined caregivers' characteristics, caregivers' need and caregivers' burden in caring for older people in general, little is known about Taiwanese caregivers of individuals with stroke or Alzheimer's disease. Cross-sectional, descriptive correlation design. Data were obtained from a convenience sample of 103 Taiwanese informal caregivers in the South of Taiwan and analysed using descriptive statistics, Pearson's correlations, multiple and hierarchical regressions and t-tests. Caregivers who had lower household incomes and were taking care of individuals with more behaviour problems had more depressive symptoms. In addition, caregivers who were older and were taking care of individuals with more behaviour problems had worse general health. Caregivers who had more emotional support had less depressive symptoms. Caregivers of persons with Alzheimer's disease had more depressive symptoms and worse general health than caregivers of persons with stroke. Only emotional support moderated the relationship between one of the stressors (household income) and depressive symptoms. The findings of this study may be helpful for nurses and other health care professionals in designing effective interventions to minimise the negative impacts of stressors on the psychological and general health of caregivers in Taiwan.

    Huntington disease (HD) is a neurodegenerative disease associated with cognitive, motor, and psychiatric deterioration over time. Although there is currently no cure for HD, there has been a surge of clinical trials available to patients with HD over the past 5 years. However, cognitive measures have generally been lacking from these trials. A brief, repeatable neuropsychological battery is needed to assess cognitive endpoints. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) may be useful for assessing change in interventional studies or for clinical monitoring. A total of 38 patients with HD were assessed using the RBANS, other cognitive tests, and the standardized HD battery (Unified Huntington's Disease Rating Scale, UHDRS) at two clinic visits approximately 16 months apart. The RBANS Attention Index, as well as individual subtest scores on Coding, Digit Span, List Recognition, Figure Copy, and Figure Recall all declined significantly over this interval. Performance on the UHDRS cognitive tests (Symbol Digit Modalities; Stroop Color, and Stroop Word) also declined, as did functional capacity. Results suggest that cognitive changes were detected both on established cognitive tasks used in HD research and on the RBANS in patients with measurable functional decline. The RBANS provided additional information about other cognitive domains affected (e.g., memory) and may be a useful measure for tracking longitudinal change.

    We present the first period study of six contact binaries in the closest globular cluster M4 the data collected from June 1995‑June 2009 and Oct 2012‑Sept 2013. New times of minima are determined for all the six variables and eclipse timing (O-C) diagrams along with the quadratic fit are presented. For all the variables, the study of (O-C) variations reveals changes in the periods. In addition, the fundamental parameters for four of the contact binaries obtained using the Wilson-Devinney code (v2003) are presented. Planned observations of these binaries using the 3.6-m Devasthal Optical Telescope (DOT) and the 4-m International Liquid Mirror Telescope (ILMT) operated by the Aryabhatta Research Institute of Observational Sciences (ARIES; Nainital) can throw light on their evolutionary status from long term period variation studies.

    We propose a model for studying binary fluids based on the mesoscopic molecular simulation technique known as multiparticle collision, where the space and state variables are continuous, and time is discrete. We include a repulsion rule to simulate segregation processes that does not require calculation of the interaction forces between particles, so binary fluids can be described on a mesoscopic scale. The model is conceptually simple and computationally efficient; it maintains Galilean invariance and conserves the mass and energy in the system at the micro- and macro-scale, whereas momentum is conserved globally. For a wide range of temperatures and densities, the model yields results in good agreement with the known properties of binary fluids, such as the density profile, interface width, phase separation, and phase growth. We also apply the model to the study of binary fluids in crowded environments with consistent results.

    Purpose Through this study we aimed to assess the educational level and employment status of adults with CHD in Germany. Data were acquired from an online survey carried out in 2015 by the German National Register for Congenital Heart Defects. A total of 1458 adults with CHD participated in the survey (response rate: 37.6%). For 1198 participants, detailed medical information, such as main cardiac diagnosis and information from medical reports, was available. Of the participants surveyed (n=1198), 54.5% (n=653) were female, and the mean age was 30 years. The majority of respondents (59.4%) stated that they had high education levels and that they were currently employed (51.1%). Patients with simple CHD had significantly higher levels of education (pemployed (p=0.01) than were patients with complex CHD. More than half of the participants had high education levels and the majority were employed. The association between CHD and its severity and individuals' educational attainment should be investigated more closely in future studies.

    Assessment of myocardial variability is clinically important in the work-up of patients with ischemic cardiomyopathy. Numerous studies in the past 2 decades demonstrated that revascularization improves left ventricular ejection fraction (LVEF), heart failure symptoms and prognosis in patients with viable myocardium. Conversely patients without viable tissue do not benefit from revascularization. Also, a substantial amount of viable myocardium (at least 25% of the left ventricle) is needed to result in improvement of LVEF. Hence, both identification and quantification on the extent of viable myocardium are required for a careful selection of candidates for revascularization. Indeed, the presence of a substantial amount of viable myocardium decreases the risk of surgery in patients with reduced LVEV. Several diagnostic techniques are available to identify myocardial viability. Positron emission tomography (PET), myocardial perfusion imaging, and stress echocardiography are considered the traditional techniques to evaluate myocardial viability. Recently, newer techniques including cardiac magnetic resonance (CMR), myocardial contrast echography (MCE) and electro-mechanical mapping have been introduced. In this manuscript the status of the currently available techniques to assess viability was reviewed. Also the relative merits of each techniques for prediction of functional recovery and prognosis was addressed. The available retrospective data support the clinical use of viability assessment. Patients with ischemic cardiomyopathy should undergo viability testing to determine therapeutic strategy. In the presence of substantial amount of viable myocardium, patients should undergo revascularization since benefits in terms of left ventricular function, remodelling, symptoms and prognosis may be anticipated. However, prospective randomized trial are needed to confirm these data

    Zonulin is the only known regulator of intestinal permeability. It is also considered as a potential inflammatory marker in several conditions such as diabetes and inflammatory bowel syndrome. The aim of the study was to investigate zonulin levels in patients with early stages of CKD and its possible correlation with inflammation, anemia and iron status parameters. Eighty-eight patients with early stages of CKD and 23 healthy volunteers were enrolled in the study. Zonulin, hepcidin-25, soluble transferrin receptor, interleukin-6 and high-sensitivity C-reactive protein were measured using commercially available assays. Zonulin was significantly lower among patients with CKD in comparison with healthy volunteers. There were no statistically significant differences in zonulin concentration between patients with and without inflammation. Zonulin was significantly correlated with hepcidin only in patients with inflammation. Zonulin was neither related to iron nor related to ferritin. Zonulin cannot be considered as an inflammatory marker in CKD. It does not play a role in the disturbances of iron metabolism in CKD. Its physiological role remains to be elucidated.

    The growing attention to the role of vitamin D in skeletal and extra-skeletal diseases over the last decade induced an increased demand for vitamin D determination as well as a dramatic rise of sales of vitamin D supplement. However, several critical points in this field remain to be clarified. We lack a clear consensus about the definition of vitamin D deficiency, insufficiency, and sufficiency. The identification of different thresholds defining vitamin D status has relevant implications in clinical practice. In fact, the worldwide prevalence of low vitamin D status is highly varying according to the level of 25(OH)D utilized to define sufficiency. Therefore, the assessment of 25-hydroxyvitamin D levels may have a critical role, but a number of different technical problems associated with its determination may interfere in interpreting the results. The hydrophobic nature of vitamin D and the tight binding to its carrier (vitamin D binding protein), the different forms circulating in blood, and the issue of standardization are among the most important factors influencing the measurement of this metabolite. Another controversial point relies on the conflicting guidance on prevention and treatment of vitamin D deficiency endorsed by different medical and scientific communities. In particular, uncertainty exists about how to replete vitamin D stores, how to maintain normal 25(OH)D levels after repletion, which form of vitamin D is preferable for supplementation, and which route of administration and dosing regimens are advisable. Finally, concerns have been raised regarding vitamin D toxicity and its adverse effects.

    Full Text Available This study investigated a potential independent association between hypovitaminosis D and suspected nonalcoholic fatty liver disease (NAFLD in a nationally representative sample of the US adolescents. Data from 1630 subjects 12–19 years of age were examined using the National Health and Nutrition Examination Survey, 2001–2004. The vitamin D status of subjects was categorized into quartiles of serum 25-hydroxyvitamin D. Subjects with serum ALT>30 U/L were classified as having suspected NAFLD. Data regarding age, sex, race, BMI, and poverty level were also analyzed in bivariate and multivariate analyses using SAS and SUDAAN software. Suspected NAFLD was identified in 12.1% of adolescents in the lowest quartile compared to 6.9% of adolescents in the second quartile, 8.0% in the third quartile, and 13.17% in the highest quartile of serum 25(OHD concentrations (=.05. In analyses utilizing vitamin D as a continuous variable, no independent association was found between Vitamin D levels and rates of elevated ALT levels. In multivariate analyses, higher risks for suspected NAFLD were observed in males and overweight adolescents; however, vitamin D status was not found to be independently associated with suspected NAFLD after adjusting for obesity.

    To evaluate the effect of a whole formula diet on nutritional and cognitive status in Alzheimer's disease patients. Patients were randomly assigned to two interventions: a whole formula diet based on lyophilised foods (Treatment Group, n=24) or nutritional advice (Control Group, n=29). Energy intake, body weight, biochemistry, Mini Nutritional Assessment (MNA) and Pfeiffer's tests were determined at baseline and at 3 months of treatment. No differences were observed between groups at baseline. Energy intake tended to increase in the Treatment Group and to decrease in the Control Group, although differences were not significant. The improvement in MNA and Pfeiffer test scores was not significantly different between groups. Body weight increased by 2.06+/-1.9 kg in the Treatment Group and by 0.32+/-3.04 kg in the Control Group (P=0.007). The increases in albumin (P=0.007), haemoglobin (P=0.002) and serum ferritin (P=0.009) were higher in the Treatment Group than in controls. A similar rate of serious adverse events (hospitalisation or death) was observed in both groups. Administration of this whole formula has a positive impact on nutritional status. The great diversity in textures and tastes enable these formulations to be administered to a wide range of patients with or without liquid dysphagia.

    It is now well accepted that theory of mind (ToM) functioning is impaired in Parkinson’s disease (PD) patients. However, what remain unknown are the functions that underlie this impairment. It has been suggested that cognitive skills may be key in this area of functioning; however, many of the cognitive tests used to assess this have relied on intact visuospatial abilities. This study aimed to examine whether deficits in ToM were generated by cognitive or visuospatial dysfunction and the mediating effect of visuospatial function on ToM performance. Fifty PD patients (31 male, 19 female; mean age = 66.34 years) and 49 healthy controls (16 male, 33 female; mean age = 67.29 years) completed a ToM task (reading the mind in the eyes) and visuospatial task (line orientation). The results revealed that current cognitive status was a significant predictor for performance on the ToM task, and that 54% of the total effect of cognitive status on ToM was mediated by visuospatial abilities. It was concluded that visuospatial functioning plays an important mediating role for the relationship between executive dysfunction and affective ToM deficits in PD patients, and that visuospatial deficits may directly contribute to the presence of affective ToM difficulties seen in individuals with PD.

    Full Text Available Objective. Several tests are available in the diagnostics of sporadic Creutzfeldt-Jakob disease (sCJD; however, none of these is conclusive. We review the values of these tests, from an intensive care unit (ICU perspective. Methods. Case report and review of the literature. Results. A 53-year-old woman initially presenting with psychiatric symptoms developed myoclonus and was admitted 1 month later to the ICU with a suspected nonconvulsive status epilepticus and respiratory insufficiency, probably due to extensive antiepileptic drug therapy. Typical MRI and EEG findings and a positive 14-3-3 protein led to the diagnosis of sCJD. All treatments were terminated, and autopsy confirmed sCJD. Conclusions. Clinical signs combined with MRI, EEG, and 14-3-3 and/or tau protein determination might be sufficient to diagnose or exclude sCJD and may therefore prevent the application of unnecessary diagnostic tests.

    BACKGROUND: Despite increased knowledge about genetic aberrations in pediatric T-cell acute lymphoblastic leukemia (T-ALL), no clinically feasible treatment-stratifying marker exists at diagnosis. Instead patients are enrolled in intensive induction therapies with substantial side effects....... In modern protocols, therapy response is monitored by minimal residual disease (MRD) analysis and used for postinduction risk group stratification. DNA methylation profiling is a candidate for subtype discrimination at diagnosis and we investigated its role as a prognostic marker in pediatric T......-ALL.

    In the last decades, there have been several efforts to clarify the role of BRCA mutational status in women with advanced ovarian cancer, demonstrating its role in cancer development, as well as the prognostic significance of BRCA genotype. Our aim is to evaluate the correlation between BRCA mutational status and disease presentation in a large series of advanced high-grade serous ovarian cancer patients. This is a retrospective multicenter study including a consecutive series of newly diagnosed high-grade serous ovarian cancer patients with International Federation of Gynecology and Obstetrics stage IIIC-IV disease, at least 18 months of follow-up time, and tested for BRCA 1/2 germline mutation status. Disease presentation was analyzed using the following variables: laparoscopic predictive index value, incidence of bulky lymph nodes, and ovarian masses. Progression-free survival was defined as the months elapsed from initial diagnosis (staging laparoscopy) and recurrent disease or last follow-up. In all, 324 high-grade serous ovarian cancer patients received BRCA testing, and 273 fulfilled inclusion criteria. BRCA1/2 germline mutations were observed in 107 women (39.2%). No differences were documented according to BRCA mutation status in terms of International Federation of Gynecology and Obstetrics stage, CA125 levels, or presence of ascites. In patients with BRCA1/2 mutations we observed a higher incidence of peritoneal spread without ovarian mass (25.2% vs 13.9%; P value = .018) and of bulky lymph nodes (30.8% vs 17.5%; P value = .010) compared with women showing BRCA1/2 wild type genotype. Furthermore, women with BRCA1/2 mutations showed high peritoneal tumor load (laparoscopic predictive index value ≥8; 42.1% vs 27.1%; P value = .016) more frequently. Focusing on survival, no differences in term of median progression-free survival were observed among women treated with primary debulking surgery and neoadjuvant chemotherapy in the group of patients with

    Because Mongolia has much higher liver disease burden than any other regions of the world, it is necessary to provide information on real-time situation of chronic liver disease in Mongolia. In this article, we reviewed studies performed in Mongolia from 2000 to 2011 on seroprevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) among healthy individuals and patients with chronic liver diseases, and on the practice patterns for the management of liver cirrhosis and hepatocellular carcinoma (HCC). According to previous reports, the seroprevalence of HBV and HCV in general population in Mongolia is very high (11.8% and 15% for HBV and HCV, respectively). Liver cirrhosis is also highly prevalent, and mortality from liver cirrhosis remained high for the past decade (about 30 deaths per 100,000 populations per year). Among patients with cirrhosis, 40% and 39% are positive for HBsAg and anti-HCV, respectively, and 20% are positive for both. The seroprevalence is similar for HCC and more than 90% of HCC patients are positive for either HBV or HCV. The incidence of HCC in Mongolia is currently among the highest in the world. The mortality from HCC is also very high (52.2 deaths per 100,000 persons per year in 2010). Partly due to the lack of established surveillance systems, most cases of HCC are diagnosed at an advanced stage. The mortality from liver cirrhosis and HCC in Mongolia may be reduced by implementation of antiviral therapy program and control of alcohol consumption.

    Studies show that alcohol consumption appears to have a disproportionate impact on people of low socioeconomic status. Further exploration of the relationship between alcohol consumption, socioeconomic status and the development of chronic alcohol-attributable diseases is therefore important to inform the development of effective public health programmes. We used systematic review methodology to identify published studies of the association between socioeconomic factors and mortality and morbidity for alcohol-attributable conditions. To attempt to quantify differences in the impact of alcohol consumption for each condition, stratified by SES, we (i) investigated the relationship between SES and risk of mortality or morbidity for each alcohol-attributable condition, and (ii) where, feasible explored alcohol consumption as a mediating or interacting variable in this relationship. We identified differing relationships between a range of alcohol-attributable conditions and socioeconomic indicators. Pooled analyses showed that low, relative to high socioeconomic status, was associated with an increased risk of head and neck cancer and stroke, and in individual studies, with hypertension and liver disease. Conversely, risk of female breast cancer tended to be associated with higher socioeconomic status. These findings were attenuated but held when adjusted for a number of known risk factors and other potential confounding factors. A key finding was the lack of studies that have explored the interaction between alcohol-attributable disease, socioeconomic status and alcohol use. Despite some limitations to our review, we have described relationships between socioeconomic status and a range of alcohol-attributable conditions, and explored the mediating and interacting effects of alcohol consumption where feasible. However, further research is needed to better characterise the relationship between socioeconomic status alcohol consumption and alcohol-attributable disease risk

    Full Text Available Hand-foot-and-mouth disease (HFMD is becoming one of the extremely common airborne and contact transmission diseases in Guangzhou, southern China, leading public health authorities to be concerned about its increased incidence. In this study, it was used an ecological study plus the negative binomial regression to identify the epidemic status of HFMD and its relationship with meteorological variables. During 2008-2012, a total of 173,524 HFMD confirmed cases were reported, 12 cases of death, yielding a fatality rate of 0.69 per 10,000. The annual incidence rates from 2008 to 2012 were 60.56, 132.44, 311.40, 402.76, and 468.59 (per 100,000, respectively, showing a rapid increasing trend. Each 1 °C rise in temperature corresponded to an increase of 9.47% (95% CI 9.36% to 9.58% in the weekly number of HFMD cases, while a one hPa rise in atmospheric pressure corresponded to a decrease in the number of cases by 7.53% (95% CI -7.60% to -7.45%. Similarly, each one percent rise in relative humidity corresponded to an increase of 1.48% or 3.3%, and a one meter per hour rise in wind speed corresponded to an increase of 2.18% or 4.57%, in the weekly number of HFMD cases, depending on the variables considered in the model. These findings revealed that epidemic status of HFMD in Guangzhou is characterized by high morbidity but low fatality. Weather factors had a significant influence on the incidence of HFMD.

Hemoglobin, serum iron, transferrin, serum transferrin receptor (sTfR, serum ferritin, transferrin saturation and iron-binding capacity, white blood cell count (WBC, erythrocyte sedimentation rate (ESR, C-reactive protein (CRP, as well as IL-6, IL-1 and TNF-α, weight and height were determined by standard methods. Hepcidin-25 (Hep-25 was assessed by weak cation exchange time-of-flight mass-spectrometry.92% and 55% of HD and PD children, respectively, were stunted and 95% and 85% were anemic. Among iron status biomarkers, serum ferritin was massively increased and significantly higher in the HD group compared to the PD group. Hep-25 was also greatly elevated in both groups. 41% of HD patients showed increments in three or more inflammatory biomarkers, while it was 2 or less in all PD subjects.The degree of stunting, the prevalence and severity of anemia in Guatemalan juvenile ESRD far exceed the national statistics for this low-income Central American country. Ferritin and Hep-25 concentrations were elevated, with the latter to an extraordinary magnitude. Additional biomarkers of inflammation not directly related to iron status were elevated as well. The role of both disease- and environment-related factors in combination best explains the magnitude of the biomarker abnormalities.

    Nonalcoholic fatty liver disease (NAFLD) spans steatosis through nonalcoholic steatohepatis, cirrhosis, and hepatocellular carcinoma (HCC) associated with striking systemic features and excess cardiovascular and liver-related mortality. The pathogenesis of NAFLD is complex and multifactorial. Endocrine derangements are closely linked with dysmetabolic traits. For example, in animal and human studies, female sex is protected from dysmetabolism thanks to young individuals' ability to partition fatty acids towards ketone body production rather than very low density lipoprotein (VLDL)-triacylglycerol, and to sex-specific browning of white adipose tissue. Ovarian senescence facilitates both the development of massive hepatic steatosis and the fibrotic progression of liver disease in an experimental overfed zebrafish model. Consistently, estrogen deficiency, by potentiating hepatic inflammatory changes, hastens the progression of disease in a dietary model of nonalcoholic steatohepatitis (NASH) developing in ovariectomized mice fed a high-fat diet. In humans, NAFLD more often affects men; and premenopausal women are equally protected from developing NAFLD as they are from cardiovascular disease. It would be expected that early menarche, definitely associated with estrogen activation, would produce protection against the risk of NAFLD. Nevertheless, it has been suggested that early menarche may confer an increased risk of NAFLD in adulthood, excess adiposity being the primary culprit of this association. Fertile age may be associated with more severe hepatocyte injury and inflammation, but also with a decreased risk of liver fibrosis compared to men and postmenopausal status. Later in life, ovarian senescence is strongly associated with severe steatosis and fibrosing NASH, which may occur in postmenopausal women. Estrogen deficiency is deemed to be responsible for these findings via the development of postmenopausal metabolic syndrome. Estrogen supplementation may at

    Objectives Parkinson’s disease (PD) patients are more likely to develop impaired nutritional status because of the symptoms, medications and complications of the disease. However, little is known about the determinants and consequences of malnutrition in PD. This study aimed to investigate the association of motor, psychiatric and fatigue features with nutritional status as well as the effects of malnutrition on different aspects of quality of life (QoL) in PD patients. Methods One hundred and fifty patients with idiopathic PD (IPD) were recruited in this study. A demographic checklist, the Unified Parkinson’s Disease Rating Scale (UPDRS), the Hospital Anxiety and Depression Scale (HADS) and the Fatigue Severity Scale (FSS) were completed through face-to-face interviews and clinical examinations. The health-related QoL (HRQoL) was also evaluated by means of the Parkinson’s Disease Questionnaire (PDQ-39). For evaluation of nutritional status, the Mini Nutritional Assessment (MNA) questionnaire was applied together with anthropometric measurements. Results Thirty seven (25.3%) patients were at risk of malnutrition and another 3 (2.1%) were malnourished. The total score of the UPDRS scale (r = −0.613, Pnutritional status [2.5 vs. 2.0; Pnutritional status. Except for stigma, all other domains of the PDQ-39 were significantly correlated with the total score of the MNA. Conclusion Our study demonstrates that disease duration, severity of motor and psychiatric symptoms (depression, anxiety) and fatigue are associated with nutritional status in PD. Different aspects of the HRQoL were affected by patients’ nutritional status especially the emotional well-being and mobility domains. PMID:24608130

    Full Text Available β-thalassemias and sickle cell anemia (SCA are the most common monogenic diseases worldwide for which curative treatments remain a desired goal. Allogeneic hematopoietic stem cell transplantation (allo-HCT, - the only curative treatment currently available for hemoglobinopaties-, has a narrow application window whereas it incurs several immunological risks. Gene therapy (GT, that is the autologous transplantation of genetically modified hematopoietic stem cells (CD34+, represents a promising new therapeutic strategy which is anticipated to reestablish effective hemoglobin production and render patients transfusion- and drug- independent without the immunological complications that normally accompany allo-HCT. Prior to the application of GT for hemoglobinopathies in the clinic, many years of extensive preclinical research were spent for the optimization of the gene transfer tools and conditions. To date, three GT clinical trials for β-thalassemia and sickle cell disease (SCD have been conducted or are in progress and 3 cases of transfusion independence in thalassemic β0/βΕ patients have been reported. In the present review, the prerequisites for successful implementation of GT, the tough pathway of GT for hemoglobinopathies towards the clinic and the knowledge gained from the first clinical trials as well as the remaining questions and challenges, will be discussed. Overall, after decades of research including achievements but pitfalls as well, the path to GT of human patients with hemoglobinopathies is currently open and highly promising...

    Full Text Available Abstract The epidemics of overweight and obesity has resulted in a significant increase of non alcoholic fatty liver disease (NAFLD, a potentially progressive condition. Currently, obesity related hepatopathy represents therefore the main cause of pediatric chronic liver disease. The first choice treatment at all ages is weight loss and/or lifestyle changes, however compliance is very poor and a pharmacological approach has become necessary. In the present article we present a systematic literature review focusing on established pediatric NALFD drugs (ursodeoxycholic acid, insulin sensitizers, and antioxidants and on innovative therapeutic options as well. Regarding the former ones, a pediatric pilot study highlighted that ursodeoxycholic acid is not efficient on transaminases levels and bright liver. Similarly, a recent large scale, multicenter randomized clinical trial (TONIC study showed that also insulin sensitizers and antioxidant vitamin E have scarce effects on serum transaminase levels. Among a large series of novel therapeutic approaches acting on recently proposed different pathomechanisms, probiotics seem hitherto the most interesting and reasonable option for their safety and tolerability. Toll-like receptors modifiers, Pentoxifylline, and Farnesoid X receptors agonists have been still poorly investigated, and will need further studies before becoming possible promising innovative therapeutic strategies.

    Introduction: Mental health decline is one of the main responsible factors for augments in health care costs, and diagnosis of Alzheimer’s disease (AD). Some studies stated physical exercise is useful for reduction in cognitive decline and AD. Moreover, a recent review argued that evidence are scarce due to few studies published and lack of configuration information of exercise protocol, such as intensity and duration of exercise, number of sessions and other relevant data, to allow appropriate assessment. Materials and Methods: Here, we discussed the possible confounders or factors responsible for these differences and possible neurophysiological mechanisms. Results: Most studies revealed a possible positive association between physical exercise and cognitive assessments. There are inconsistencies in studies design responsible for varying use of cognitive assessments and different assessments of fitness. However, these studies do not fail to provide evidence about the benefits of exercise, but fail to make it possible because of the lack of dose-response information in AD patients. Physical exercise of moderate intensity should be considered as standard recommendation to reduce cognitive decline, probably due to the improvement in neurodegenerative mechanisms, and the increase in neuroplastic and neuroprotective neurotrophic factors. Conclusion: Therefore, it is suggested that physical exercise is an important neuroprotective modulator, bringing significant control of the disease and amplifying brain functions. PMID:29238394

    Full Text Available Incidence of leaf blast on nursery plants and pitting disease on maturing banana bunches has been recorded in banana plantations during rainy season in Eastern India during 2014 to 2015. Taxonomical identification as well as DNA sequence analysis of the internal transcribed spacer region of fungus isolated from affected tissue culture derived plantlets and fruits confirmed the pathogen to be Pyricularia angulata Hashioka “in both the cases”. Koch’s postulates were proved on young plantlets as well as on maturing fruits of cv. Grand Naine under simulated conditions. Evolutionary history was inferred and presented for our P. angulata strain PG9001 with GenBank accession no. KU984740. The analysis indicated that the P. angulata is phylogenitically distinct from other related species related to both Pyricularia and Magnaporthe. Detailed symptoms of blast lesions on young leaves, transition leaves, mid rib, petioles, peduncle, maturing bunches, bunch stalks and cushions were documented. Notably, the distinct small pitting spots on maturing bunches reduced the visual appeal of mature fruits. Appearance of pitting symptoms on fruits in relation with age of fruits and their distribution pattern on bunch and fingers was also documented in detail. Further, the roles of transitory leaves, weed hosts, seasonality on disease occurrence have also been documented.

    The cholinergic signalling system has been an attractive pathway to seek targets for modulation of arousal, cognition, and attention which are compromised in neurodegenerative and neuropsychiatric diseases. The acetylcholine muscarinic receptor M1 and M4 subtypes which are highly expressed in the central nervous system, in cortex, hippocampus and striatum, key areas of cognitive and neuropsychiatric control, have received particular attention. Historical muscarinic drug development yielded first generation agonists with modest selectivity for these two receptor targets over M2 and M3 receptors, the major peripheral sub-types hypothesised to underlie the dose-limiting clinical side effects. More recent compound screening and medicinal chemistry optimization of orthosteric and allosteric agonists, and positive allosteric modulators binding to sites distinct from the highly homologous acetylcholine binding pocket have yielded a collection of highly selective tool compounds for preclinical validation studies. Several M1 selective ligands have progressed to early clinical development and in time will hopefully lead to useful therapeutics for treating symptoms of Alzheimer's disease and related disorders.

    2013-06-01

    A questionnaire was widely distributed in 2011 to estimate the global prevalence of Marek's disease (MD) and gain a better understanding of current control strategies and future concerns. A total of 112 questionnaires were returned representing 116 countries from sources including national branch secretaries of the World Veterinary Poultry Association, vaccine, breeder, and production companies, as well as MD researchers from various backgrounds. Each country listed on a questionnaire was recorded as an individual entry, and on average there were 2.0 entries per country (median 1; range 1-13). All flock types were listed as having increased MD incidence during the last 10 yr in close to 50% of countries by at least one respondent, with the majority of these countries located within French-speaking Africa, Eastern Europe, East Asia, and South America. Only 18 countries (16%) indicated increasing MD incidence was likely due to higher virulent strains, while the presence of other immunosuppressive diseases was a more common explanation. Increased use of CVI988/Rispens was cited as the most likely reason for decreasing MD incidence in 49 countries (42%). In the United States, MD incidence has continued to decrease during the last 10 yr, reaching a record low in 2007 (0.0008%) as measured by leukosis condemnation rates in broilers at slaughter. However, a recent increase of leukosis condemnations in North Carolina and Pennsylvania needs to be closely monitored.

    Full Text Available Background/Aims: Inflammatory bowel disease (IBD primarily involves the intestinal tract and can affect vitamin absorption. This study was designed to assess the prevalence of vitamin B₁₂ and folate deficiencies in patients with IBD, and to identify the risk factors associated with abnormal serum vitamin B₁₂ and folate levels.Methods: We evaluated the medical records of 195 patients with Crohn's disease (CD and 62 patients with ulcerative colitis (UC, and selected 118 healthy subjects for the control group.Results: There were more CD patients with vitamin B₁₂ deficiency than UC patients (14.9% vs. 3.2%, P=0.014 and controls (14.9% vs. 4.2%, P=0.003. The prevalence of folate deficiency was higher in CD patients than in controls (13.3% vs. 3.4%, P=0.004. There were no significant differences in the serum vitamin B₁₂ and folate statuses of the UC and control groups. Patients with prior ileal or ileocolic resection showed a higher prevalence of abnormal vitamin B₁₂ levels than those without prior resection (n=6/16, n=23/179; P=0.018. A disease duration within 5 years was a risk factor of abnormal folate levels in CD patients.Conclusions: This study showed that vitamin B₁₂ and folate deficiencies were more common in patients with CD than in UC patients and controls. Prior ileal or ileocolonic resection was a risk factor of serum vitamin B₁₂ abnormalities, and a disease duration within 5 years was a risk factor of low serum folate levels in CD patients.

The aim of this study was to investigate oral health status in patients with diabetes mellitus type 2 in relation to metabolic control of the disease. Methods. The study included 47 randomly sampled diabetics patients, divided into two groups; those with poorly controlled diabetes (glycosylated haemoglobin - HbA1c ≥9% and those with better controlled diabetes (HbA1c<9%. All patients completed a questionnaire about their medical and oral health. Decayed, missing, and filled teeth (DMFT and plaque index (PI, bleeding on probing (BOP, probing pocket depth (PPD and clinical attachment loss (CAL were recorded. Results. The patients with poorly controlled diabetes had a significantly higher number of tooth caries compared to those with better controlled diabetes (6.5±4.3 vs. 4.3±2.9; p<0.05. Of periodontal parameters, only PPD was significantly higher in the patients with poorly controlled diabetes than in those with better controlled diabetes (5.8±0.9 vs. 5.2±0.8; p<0.05. DMFT index, PI, PPD and CAL exhibited positive correlation only with patients' age. Conclusion. The study indicates that there is a relationship between poor control of diabetes and caries, and periodontal disease.

    To develop a predictive dynamic model to generate and analyse the future status of the incidence rate of ischaemic heart disease in a population of 25 years and over in Mexico, according to the variation in time of some risk factors. Retrospective ecological study performed during the period 2013-2015, in San Luis Potosí City, Mexico. Secondary databases that corresponded to the years 2000, 2005, and 2010, were used along with official indicators of the 58 municipalities of the state of San Luis Potosí. Eight indicators were analysed at municipality level, using principal components analysis, structural equation modelling, dynamic modelling, and simulation software methods. Three components were extracted, which together explained 80.43% of the total variance of the official indicators used. The second component had a weight of 16.36 units that favoured an increase of the disease analysed. This component was integrated only by the indicator AGE 60-64 and the expected stage of it increasing. The structural model confirmed that the indicators explain 42% of the variation of this disease. The possible stages for the years 2015, 2020, and 2025 are 195.7, 240.7, and 298.0, respectively for every 100,000 inhabitants aged 25 and over. An exponential increase in the incidence rate of ischaemic heart disease is expected, with the age of 60-64 years being identified as the highest risk factor.

    Full Text Available Hepatic glycogen storage diseases (GSDs are genetic diseases associated with fasting hypoglycemia. Periodic intake of uncooked cornstarch is one of the treatment strategies available for those disorders. For reasons that are still not clear, patients with hepatic GSDs may be overweight. Aims: To assess nutritional status and body composition in patients with hepatic GSDs receiving uncooked cornstarch. Methods: The sample included 25 patients with hepatic GSD (type Ia = 14; Ib = 6; III = 3; IXα = 1; IXβ = 1, with a median age of 11.0 years (interquartile range [IQR] = 9.0-17.5, matched by age and gender with 25 healthy controls (median age = 12.0 years, IQR = 10.0-17.5. Clinical, biochemical, and treatment-related variables were obtained from medical records. Nutritional status and body composition were prospectively evaluated by bioelectrical impedance. Results: Patients and controls did not differ with regard to age and gender. Height was significantly reduced in patients (median = 1.43 m, IQR = 1.25-1.54 in comparison to controls (median = 1.54 m, IQR = 1.42-1.61; P = .04. Body mass index for age z -score and fat mass percentage were higher in patients (median = 1.84, IQR = 0.55-3.06; and 27.5%, IQR = 22.6-32.0, respectively than in controls (median = 0.86, IQR = −0.55 to 1.82; P = .04 and 21.1%, IQR = 13.0-28.3; P = .01, respectively. When patients were stratified by type, those with GSD Ia had significantly higher adiposity (median fat mass = 28.7%, IQR = 25.3-32.9 than those with GSD III and GSD IXα/β (median fat mass = 20.9%, IQR = 14.9-22.6; P = .02. Conclusions: Our findings suggest that patients with hepatic GSD on treatment with cornstarch, especially those with GSD Ia, exhibit abnormalities in nutritional status and body composition, such as short stature and a trend toward overweight and obesity.

    Full Text Available The aim of the study was to evaluate the current state of nutrition of patients with rheumatic diseases in the Polish population. Material and methods : An anonymous questionnaire study was carried out among the patients of the Institute of Rheumatology in Warsaw in the fourth quarter of 2012. Five hundred questionnaires were distributed, and 397 questionnaires were collected and accepted for further analysis (response rate = 79%. Results: Overweight or obesity was present in more than half (53% of the patients (overweight in 30.5% of respondents, obesity in 22.6%. Among obese subjects, 43% of men and 37% of women in the study think that their diet is correct. Sixty-eight percent of respondents declared that they do not follow any special diet and only 18% declared that they follow a diet with a reduced quantity of monosaccharides (no sweets. A milk-free diet was followed by 7% of respondents, a meat-free diet by 6%, and a fruit-and-vegetable diet by 5%. Dietary supplements were regularly used by 26.7% of respondents, whereas 33.8% did not use them at all. The average assessment of physical aptitude (Health Assessment Questionnaire – HAQ in the group of respondents was 0.71. No statistically significant differences were found between higher level of disability (e.g. HAQ ≥ 1 and the type of diet followed (p = 0.678 or body mass index (BMI value (p = 0.864 in relation to persons with the value of HAQ < 1. Conclusions : More than half of patients suffering from rheumatic diseases are overweight or obese, which corresponds to the body weight profile of the population of Poland. Most patients diagnosed with rheumatic diseases do not follow any special diet. In spite of the frequent use of dietary supplements, the patients do not consult a doctor or a dietician about it. The type of diet and BMI value do not differ according to the level of disability.

    Pain is one of the most disabling symptoms of rheumatoid diseases. Patients with pain secondary to osteoarthritis (OA), rheumatoid arthritis (RA), ankylosing spondylitis (AS) or gout require effective analgesic treatment, and the physician's task is to select a drug that is best suited for an individual patient. The choice of pharmacotherapy should be based both on drug potency and clinical efficacy, and its safety profile, particularly in the elderly population, as the number of comorbidities (and hence the risk of treatment complications and drug interactions) rises with age. In cases involving a high risk of gastrointestinal complications or concerns about hepatotoxicity, with a low cardiovascular risk, the first-line nonsteroidal anti-inflammatory drugs to consider should be coxibs including etoricoxib.

    This review illustrates the state of the art clinical applications and the future perspectives of ultrasound elastographic methods for the evaluation of chronic liver diseases, including the most widely used and validated technique, transient elastography, followed by shear wave elastography and strain imaging elastography. Liver ultrasound elastography allows the non-invasive evaluation of liver stiffness, providing information regarding the stage of fibrosis, comparable to liver biopsy which is still considered the gold standard; in this way, it can help physicians in managing patients, including the decision as to when to start antiviral treatment. The characterization of focal liver lesions and the prognostic role of the elastographic technique in the prediction of complications of cirrhosis are still under investigation.

    Patients with chronic kidney disease (CKD) often experience a decline in their nutrient intake starting at early stages of CKD. This reduction in intake can affect both energy-producing nutrients, such as carbohydrates, proteins, and fats, as well as vitamins, minerals, and trace elements. Knowledge of the burden and bioactivity of vitamins and their effect on the health of the patients with CKD is very incomplete. However, without sufficient data, the use of nutritional supplements to prevent inadequate intake may result in either excessive or insufficient intake of micronutrients for people with CKD. The purpose of this article is to briefly summarize the current knowledge regarding vitamin requirements for people with stages 3, 4, or 5 CKD who are not receiving dialysis.

    Inflammatory bowel disease (IBD) has the propensity to affect patients who are in their late teens and early 20s, an age when most people decide on their educational and career directions. This review describes the effects that IBD has on the continuum of education and employment. Patients with Crohn's disease and ulcerative colitis attain a similar level of education as that of the general population. The quality of life of such patients in school, as measured by both patients' and teachers' perceptions, indicates that, despite the difficulties that students face in terms of missed school time and physical inconveniences, teachers are generally perceived by students to have favorable attitudes toward helping them. Even though earlier work in the area of employment has suggested that the occurrence of IBD is clustered among people in white-collar positions, recent data have suggested that certain environmental risks for IBD (i.e., sedentary or indoor jobs) may be associated with jobs classified as being white-collar, and therefore having a white-collar job may in itself not be a risk factor for the development of IBD. Patients with IBD have a higher rate of nonparticipation in the labor force, and the participation rate seems to maintain steady levels over time. A majority of patients with IBD continue in the same employment positions over a period of years. Patients with IBD, especially those who have undergone surgery, took more sick leave than their counterparts without IBD. A majority of patients with IBD favored the disclosure of their diagnosis to their employers and perceived little discrimination in the workplace. Furthermore, most employers were perceived by their employees with IBD as having fair attitudes toward the compensation provided for their employees with IBD.

    Obese subjects frequently show skin diseases. However, less attention has been paid to the impact of obesity on skin disorders until now. The purposes of this study are: to highlight the incidence of some dermatoses in obese subjects and to study the water barrier function of the obese skin using transepidermal water loss (TEWL). Sixty obese subjects and 20 normal weight volunteers were recruited. Obese group was further divided into three body mass index (BMI) classes: class I (BMI 30-34.9 kg/m(2)), class II (BMI 35-39.9 kg/m(2)) and class III (BMI 40 g/m(2)). All subjects attended dermatological examination for skin diseases. To assess barrier function, TEWL measurements were performed on the volar surface of the forearm using a tewameter. The results of this study showed that: (i) obese subjects show a higher incidence of some dermatoses compared with normal-weight controls; in addition the dermatoses are more, frequent as BMI increases; (ii) the rate of TEWL is lower in obese subjects, than in the normal-weight subjects, particularly in patients with intra-abdominal obesity. Specific dermatoses as skin tags, striae distensae and plantar hyperkeratosis, could be considered as a cutaneous stigma of severe obesity. The low permeability of the skin to evaporative water loss is observed in obese subjects compared with normal weight control. Although the physiological mechanisms are still unknown, this finding has not been previously described and we believe that this may constitute a new field in the research on obesity.

    A serological survey for the prevalence of protective level of antibody to Foot-and-mouth disease (FMD) was carried out in 10 border districts in Peninsular Malaysia. A liquid phase blocking ELISA kit prepared and standardized by World Reference Laboratory (WRL) for FMD was used for the testing. A total of 800 serum samples collected by a random process were tested for protective level of antibody for virus types O, A and Asia I. An overall mean prevalence for antibody to FMD in the 'immune-belt' region was found to be 51.0%, 37.3%, 53.6% for virus types Q, A, and Asia I respectively and 28.9% for all the three sero-types. The percentage of cattle population having protective level of antibody was too low to prevent active spread of FMD infection. There was also substantial variation in the prevalence of antibody detected at the district level and varied from a low mean of 18.8% for the State of Kedah and a high of 67.5% for the district of Besut. More than 70% of the population need to have protective level of antibody to effectively prevent disease spread. The States of Kedah and Kelantan had variable levels of vaccination coverage from 1994 and had less than 45% coverage for the year 1996. A coverage of more than 90% would be essential to maintain high herd immunity and the current high variability in the vaccination coverage at the district level will only favour a higher infection on rate in the field.

    Full Text Available This study aims to assess the autoimmunological status and forms of celiac disease (CD among children with type 1 diabetes mellitus (T1DM . The study group comprises 27 patients at the mean age of 12.30 years (±SD 3.12. The measurement of the level of diabetes-specific antibodies and organ-specific antibodies was gained at the T1DM-onset and repeated annually. The following risk factors influencing time of CD diagnosis were analyzed: age, sex, T1DM duration, autoantibodies, and HLA-haplotype. The prevalence of antibodies was GADA-74%, IAA-63%, IA2A-67%, ATA-11%, and ATG-4%. The intestinal biopsy revealed in 19% no changes and in 77% stage 3 (Marsh scale. In most cases, no clinical manifestation of CD was observed. The diagnosis of Hashimoto's disease was made twice. The negative correlation between the age at T1DM-onset and the interval between onset of T1DM and CD (r=‐0.35, p<.05 was noted. The high-comorbidity ratio of CD and thyroiditis with T1DM demands regular screening tests especially in the first years after T1DM-onset.

    Full Text Available Growth failure is one of the most common and profound clinical manifestation of chronic kidney disease (CKD in infants, children and adolescents. The aim of this study was to assess the nutritional status of Egyptian children with end-stage renal disease (ESRD on regular hemodialysis (HD. The study included 50 Egyptian children with ESRD on regular HD, following-up at the Pediatric Nephrology unit, Cairo University. History, including dietary history, was taken for all patients and clinical examination was performed on all of them. Body weight, standing height, height or length SD score, the skin fold thickness, mid-arm circumference, mid-arm muscle circumference and mid-arm muscle circumference area were also assessed. The height of the patients was the most affected anthropometric parameter, as 78% of the patients were shorter (height SDS below -3. Body weight is less affected than height, as body weight SDS of 34% of patients was less than -3 SDS. In addition, the body mass index of 16% of the patients was 97 th percentile. Although most ESRD patients received adequate protein and caloric intake, their growth was markedly affected, especially with longer period on HD. We suggest that assessment of growth parameters should be performed at a minimum period of every six months in children with CKD stages 2-3. For children with more advanced CKD (stages 4-5 and 5D, more frequent evaluation may be warranted due to the greater risk of abnormalities.

    The pathogenesis of osteosarcoma involves complex genetic and epigenetic factors. This study was to explore the impact and clinical relevance of long non-coding RNA (lncRNA), Taurine up-regulated gene 1 (TUG1) on patients with osteosarcoma. Seventy-six osteosarcoma tissues and matched adjacent normal tissues were included for analysis. The plasma samples were obtained from 29 patients with osteosarcoma at pre-operation and post-operation, 42 at newly diagnosed, 18 who experienced disease progression or relapse, 45 post-treatment, 36 patients with benign bone tumor, and 20 healthy donors. Quantitative real-time reverse transcript polymerase chain reactions were used to assess the correlation of the expression levels of TUG1 with clinical parameters of osteosarcoma patients. TUG1 was significantly overexpressed in the osteosarcoma tissues compared with matched adjacent normal tissues (P TUG1 strongly correlated with poor prognosis and was an independent prognostic indicator for overall survival (HR = 2.78, 95% CI = 1.29-6.00, P = 0.009) and progression-free survival (HR = 1.81, 95% CI = 1.01-3.54, P = 0.037). Our constructed nomogram containing TUG1 had more predictive accuracy than that without TUG1 (c-index 0.807 versus 0.776, respectively). In addition, for plasma samples, TUG1 expression levels were obviously decreased in post-operative patients (mean ΔCT -4.98 ± 0.22) compared with pre-operation patients (mean ΔCT -6.09 ± 0.74), and the changes of TUG1 expression levels were significantly associated with disease status. Receiver operating characteristic (ROC) curve analysis demonstrated that TUG1 could distinguish patients with osteosarcoma from healthy individuals compared with alkaline phosphatase (ALP) (the area under curve 0.849 versus 0.544). TUG1 was overexpressed in patients with osteosarcoma and strongly correlated with disease status. In addition, TUG1 may serve as a molecular indicator in maintaining surveillance

    Incompatibility of red cell and platelet antigens can lead to maternal alloimmunization causing hemolytic disease of the fetus & newborn and fetal neonatal alloimmune thrombocytopenia respectively. As the molecular background of these polymorphisms emerged, prenatal testing using initially fetal DNA obtained from invasively obtained amniotic fluid or chorionic villus was implemented. This evolved into testing using maternal plasma as source of fetal DNA, and this is in routine use as a safe non-invasive diagnostic that has no risk to the fetus of alloimmunization or spontaneous miscarriage. These tests were initially applied to high risk pregnancies, but has been applied on a mass scale, to screen fetuses in D-negative pregnant populations as national screening programs. Fetal neonatal alloimmune thrombocytopenia management has had comparatively small take up in non-invasive testing for causative fetal platelet alleles (e.g., HPA-1A), but mass scale genotyping of mothers to identify at risk HPA-1b1b pregnancies and their treatment with prophylactic anti-HPA-1A is being considered in at least one country (Norway).

  8. The role of stents in the treatment of congenital heart disease: Current status and future perspectives

    Intravascular or intracardiac stenoses occur in many forms of congenital heart disease (CHD). Therefore, the implantation of stents has become an accepted interventional procedure for stenotic lesions in pediatric cardiology. Furthermore, stents are know to be used to exclude vessel aneurysm or to ensure patency of existing or newly created intracardiac communications. With the further refinement of the first generation of devices, a variety of “modern” stents with different design characteristics have evolved. Despite the tremendous technical improvement over the last 20 years, the “ideal stent” has not yet been developed. Therefore, the pediatric interventionalist has to decide which stent is suitable for each lesion. On this basis, currently available stents are discussed in regard to their advantages and disadvantages for common application in CHD. New concepts and designs developed to overcome some of the existing problems, like the failure of adaptation to somatic growth, are presented. Thus, in the future, biodegradable or growth stents might replace the currently used generation of stents. This might truly l
