Full Text Available The health status was analyzed in extremely preterm infants at a postconceptual age of 38–40 weeks and in the first year of life. All the infants in the analyzed group were shown to have respiratory disorders, severe perinatal CNS lesions, and the high incidence of bronchopulmonary dysplasia and infectious and inflammatory diseases. In the first year of life, these children belonged to a group of the frequently ill. Dysfunction of the digestive system and intestinal microflora and residual signs of rickets were detected in the majority of the patients; the manifestations of bronchopulmonary dysplasia persisted in 50%. 40% of the infants had disabling complications.
Extreme weather events and infectious disease outbreaks.

Human-driven climatic changes will fundamentally influence patterns of human health, including infectious disease clusters and epidemics following extreme weather events. Extreme weather events are projected to increase further with the advance of human-driven climate change. Both recent and historical experiences indicate that infectious disease outbreaks very often follow extreme weather events, as microbes, vectors and reservoir animal hosts exploit the disrupted social and environmental conditions of extreme weather events. This review article examines infectious disease risks associated with extreme weather events; it draws on recent experiences including Hurricane Katrina in 2005 and the 2010 Pakistan mega-floods, and historical examples from previous centuries of epidemics and 'pestilence' associated with extreme weather disasters and climatic changes. A fuller understanding of climatic change, the precursors and triggers of extreme weather events and health consequences is needed in order to anticipate and respond to the infectious disease risks associated with human-driven climate change. Post-event risks to human health can be constrained, nonetheless, by reducing background rates of persistent infection, preparatory action such as coordinated disease surveillance and vaccination coverage, and strengthened disaster response. In the face of changing climate and weather conditions, it is critically important to think in ecological terms about the determinants of health, disease and death in human populations.

Evaluate whether mortality after discharge is elevated in geriatric fracture patients whose lower extremity weight-bearing is restricted. Retrospective cohort study SETTING: Urban Level 1 trauma center PATIENTS/PARTICIPANTS: 1746 patients >65 years of age INTERVENTION: Post-operative lower extremity weight-bearing status MAIN OUTCOME MEASURE: Mortality, as determined by the Social Security Death Index RESULTS: Univariate analysis demonstrated that patients who were weight-bearing as tolerated on bilateral lower extremities (BLE) had significantly higher 5-year mortality compared to patients with restricted weight-bearing on one lower extremity and restricted weight-bearing on BLE (30%, 21% and 22% respectively, p bearing as tolerated on BLE, restricted weight-bearing on one lower extremity had a hazard ratio (HR) of 0.97 (95% confidence interval 0.78 to 1.20, p = 0.76) and restricted weight-bearing in BLE had a HR of 0.91 (95% confidence interval 0.60 to 1.36, p = 0.73). In geriatric patients, prescribed weight-bearing status did not have a statistically significant association with mortality after discharge, when controlling for age, sex, body mass index, medical comorbidities, Injury Severity Scale (ISS), mechanism of injury, nonoperative treatment and admission GCS. This remained true in when the analysis was restricted to operative injuries only. Copyright © 2017 Elsevier Ltd. All rights reserved.

Using Blood Indexes to Predict Overweight Statuses: An Extreme Learning Machine-Based Approach.

Directory of Open Access Journals (Sweden)

Huiling Chen

Full Text Available The number of the overweight people continues to rise across the world. Studies have shown that being overweight can increase health risks, such as high blood pressure, diabetes mellitus, coronary heart disease, and certain forms of cancer. Therefore, identifying the overweight status in people is critical to prevent and decrease health risks. This study explores a new technique that uses blood and biochemical measurements to recognize the overweight condition. A new machine learning technique, an extreme learning machine, was developed to accurately detect the overweight status from a pool of 225 overweight and 251 healthy subjects. The group included 179 males and 297 females. The detection method was rigorously evaluated against the real-life dataset for accuracy, sensitivity, specificity, and AUC (area under the receiver operating characteristic (ROC curve criterion. Additionally, the feature selection was investigated to identify correlating factors for the overweight status. The results demonstrate that there are significant differences in blood and biochemical indexes between healthy and overweight people (p-value < 0.01. According to the feature selection, the most important correlated indexes are creatinine, hemoglobin, hematokrit, uric Acid, red blood cells, high density lipoprotein, alanine transaminase, triglyceride, and γ-glutamyl transpeptidase. These are consistent with the results of Spearman test analysis. The proposed method holds promise as a new, accurate method for identifying the overweight status in subjects.

The manifestation of motor signs in Huntington's disease (HD) has a well-known inverse relationship with HTT CAG repeat length, but the prediction is far from perfect. The probability of finding disease modifiers is enhanced in individuals with extreme HD phenotypes. We aimed to identify extreme HD motor phenotypes conditional on CAG and age, such as patients with very early or very late onset of motor manifestation. Retrospective data were available from 1,218 healthy controls and 9,743 HD participants with CAG repeats ≥40, and a total of about 30,000 visits. Boundaries (2.5% and 97.5% quantiles) for extreme motor phenotypes (UHDRS total motor score (TMS) and motor age-at-onset) were estimated using quantile regression for longitudinal data. More than 15% of HD participants had an extreme TMS phenotype for at least one visit. In contrast, only about 4% of participants were consistent TMS extremes at two or more visits. Data from healthy controls revealed an upper cut-off of 13 for the TMS representing the extreme of motor ratings for a normal aging population. In HD, boundaries of motor age-at-onset based on diagnostic confidence or derived from the TMS data cut-off in controls were similar. In summary, a UHDRS TMS of more than 13 in an individual carrying the HD mutation indicates a high likelihood of motor manifestations of HD irrespective of CAG repeat length or age. The identification of motor phenotype extremes can be useful in the search for disease modifiers, for example, genetic or environmental such as medication. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.
Extreme delta brush evolving into status epilepticus in a patient with anti-NMDA encephalitis

Directory of Open Access Journals (Sweden)

Aline Herlopian, MD

2017-01-01

Full Text Available Extreme delta brush (EDB is an EEG pattern unique to anti-NMDA encephalitis. It is correlated with seizures and status epilepticus in patients who have a prolonged course of illness. The etiology of the underlying association between EDB and seizures is not understood. We present a patient with anti-NMDA encephalitis who developed status epilepticus evolving from the high frequency activity of the extreme delta brush. This case demonstrates that EDB is not only a marker for a greater propensity for seizures but also directly implicated in seizure generation.

We performed both peripheral and coronary angiographies in 52 patients with an arteriosclerosis in lower extremities. The severity of arteriosclerotic narrowing of the coronary and peripheral arteries were compared on angiographies. An angiographic vascular score(AVS, 0-5) reflecting the number and the degree of stenosis in 12 lower extremity arteries and three major coronary arteries was assigned to each angiogram and the sun of scores in the lower extremity arteries was compared with the incidence of significant coronary artery disease (more than grade 3) and coronary score. Relation of incidence and severity of vascular stenosis and risk factors (diabetes metallitus, hypertension, smoking, and hypercholesterolemia) was also analyzed. Thirty-four of 52 patients (65%) had an angiographically significant coronary artery disease. Thirteen of these 34 patients (38%) had no clinical symptom and sign of the ischemic heart disease. There was no statistically significant difference in the incidence and severity of coronary artery disease between high (more than 30) and low AVS group in lower extremity (p>0.14). All patients had at least one risk factor and 49 of 52 patients (94%) had multiple risk factors. Coronary angiography was normal in there patients with only one risk factors, and angiographically significant coronary artery disease existed in nine of 16 cases (56.3%) with two risk factors. 13 of 17 case (76.5%) with three risk factors, and 12 of 16 cases (75.0%) with all four risk factors. There were no significant correlations between individual risk factors and incidence, severity of arteriosclerosis in coronary and lower extremity arteries. In conclusion, angiographic evaluation of the coronary artery disease in patients with lower extremity arteriosclerosis is necessary because of the high chance of coronary artery disease and difficulty in the prediction of coronary artery disease with a severity of the peripheral arteriosclerosis, presence of various risk

Kimura's disease is a rare chronic inflammatory disorder predominantly affecting young Asian male patients, occurring mainly in the head and neck regions. Kimura's disease of the upper extremity is extremely rare, and previous case reports in the literature show similar imaging characteristics with consistent location at the medial epitrochlear region, predominantly with unilateral involvement. We present the first reported case of Kimura's disease affecting the anterolateral aspect of the upper arm, sparing the medial epitrochlear region, illustrating that with typical MR appearance and serology, the involvement of this rare disease in an atypical location still warrants consideration of this diagnosis. There was also bilateral asymmetrical involvement in our patient, suggesting the possibility of a propensity for Kimura's disease affecting the upper extremities to have bilateral involvement, which may necessitate imaging of the clinically asymptomatic contralateral limb in these patients for early lesion identification and treatment.

The health gap between Indigenous and non-Indigenous Australians may be exacerbated by climate change if temperature extremes have disproportionate adverse effects on Indigenous people. To explore this issue, we analysed the effect of temperature extremes on hospital admissions for respiratory diseases, stratified by age, Indigenous status and sex, for people living in two different climates zones in the Northern Territory during the period 1993–2011. We examined admissions for both acute and chronic respiratory diagnoses, controlling for day of the week and seasonality variables. Our analysis showed that: (1) overall, Indigenous hospital admission rates far exceeded non-Indigenous admission rates for acute and chronic diagnoses, and Top End climate zone admission rates exceeded Central Australia climate zone admission rates; (2) extreme cold and hot temperatures were associated with inconsistent changes in admission rates for acute respiratory disease in Indigenous and non-Indigenous children and older adults; and (3) no response to cold or hot temperature extremes was found for chronic respiratory diagnoses. These findings support our two hypotheses, that extreme hot and cold temperatures have a different effect on hospitalisations for respiratory disease between Indigenous and non-Indigenous people, and that these health risks vary between the different climate zones. We did not, however, find that there were differing responses to temperature extremes in the two populations, suggesting that any increased vulnerability to climate change in the Indigenous population of the Northern Territory arises from an increased underlying risk to respiratory disease and an already greater existing health burden.

Vitamins K and D are important for the function of vitamin K-dependent proteins in joint tissues. It is unclear if these nutrients are mutually important to functional outcomes related to knee osteoarthritis (OA). We evaluated the association of vitamin K and D sufficiency with lower-extremity function in the Health, Aging Body Composition Knee OA Sub-study (Health ABC) and conducted a replication analysis in an independent cohort, the Osteoarthritis Initiative (OAI). In Health ABC (60% female, 75±3 years) baseline nutrient status was measured using circulating vitamin K and 25(OH)D. Lower-extremity function was assessed using the short physical performance battery (SPPB) and usual 20-meter gait speed. In the OAI (58% female, 61±9 years), baseline nutrient intake was estimated by food frequency questionnaire. Lower-extremity function was assessed using usual 20-meter gait speed and chair stand completion time. Multivariate mixed models were used to evaluate the association of vitamin K and D status and intake with lower-extremity function over 4-5 years. Health ABC participants with sufficient plasma vitamin K (≥1.0 nmol/L) and serum 25(OH)D (≥50 nmol/L) generally had better SPPB scores and faster usual gait speed over follow-up (p≤0.002). In the OAI, sufficient vitamin K and vitamin D intake combined was associated with overall faster usual gait speed and chair stand completion time over follow-up (p≤0.029). Sufficient vitamin K status combined with sufficient vitamin D status was associated with better lower-extremity function in two knee OA cohorts. These findings merit confirmation in vitamin K and D co-supplementation trials. This article is protected by copyright. All rights reserved. This article is protected by copyright.

Poverty alleviation programs for the extreme poor improve participants' economic status and may impact other important outcomes that are seldom evaluated. A program targeted to the extreme poor by BRAG, a development organization in Bangladesh, has been successful in significantly alleviating extreme poverty. We hypothesized that the program also improved the nutritional status of women and preschool children. A nonequivalent control, pre- and posttest quasi-experimental design that was longitudinal at the village level was used to test the hypotheses. Data were collected from a random sample of 4,131 children and 3,551 women from 3,409 households in 159 villages of 3 northern districts of Bangladesh in 2002 and 2006. Linear mixed random-intercept models accounted for clustering effects and potential confounders. The weight-for-height of children between 24 and 35 months of age from program households was significantly higher (p growth and body-composition indicators in three other age categories of preschool children or in women. These results are important, as this is a large-scale program that has already been extended to more than half the country. The findings will contribute to judging the cost-benefit and cost-effectiveness of the program and in garnering support for the expansion of such programs.

Clinical and pathologic features in Alzheimer's disease (AD) patients differ depending on the age of onset. The aim of our study was to compare the regional cerebral blood flow (rCBF) patterns of younger, elderly, and extremely elderly patients with AD with that of controls to characterize the rCBF patterns in extremely elderly patients with AD. Single photon emission CT (SPECT) was performed in 113 patients with probable AD, including 34 younger (<70 years), 41 elderly (70-84 years), and 38 extremely elderly (≥85 years) patients divided according to age at examination. The SPECT data were analyzed using three-dimensional stereotactic surface projection (3D-SSP). No significant differences regarding gender, duration of disease, education, and Mini-Mental State Examination score were found among the groups. As compared with controls, younger and elderly AD demonstrated significant reduction of rCBF in the temporo-parietal areas, posterior cingulate cortices and precunei, which is considered to be a characteristic rCBF pattern in AD. On the other hand, the extremely elderly AD group demonstrated significant reduction of rCBF in the frontal and medial temporal areas, in addition to the temporo-parietal areas, posterior cingulate cortices and precunei, but the reductions were milder than in those in younger and elderly AD groups. The extremely elderly patients with AD showed atypical rCBF patterns in AD compared to younger and elderly patients with AD. Our data suggest that pathological features in extremely elderly AD may be different from those in younger and elderly AD and that diseases different from AD, such as senile dementia of the neurofibrillary tangle type may be clinically diagnosed as extremely elderly AD.

OBJECTIVE - : Sex hormones may be critical determinants of ischemic heart disease and death in women, but results from previous studies are conflicting. To clarify this, we tested the hypothesis that extreme plasma concentrations of endogenous estradiol and testosterone are associated with risk...... for ischemic heart disease, 36% (18%-58%) higher for any death, and 38% (15%-65%) higher for death from other causes than cardiovascular disease and cancer. These results were similar for postmenopausal women alone. CONCLUSIONS - : In women, extreme low concentrations of endogenous estradiol were associated...
Employment and weight status: The extreme case of body concern in South Korea.

For an industrialized nation, obesity rates in South Korea are extremely low. Yet, reflecting an extremely fat-averse, thin-positive society, efforts to lose weight are now reportedly very common. Since the 1980s, South Korea has experienced an increasingly flexible and insecure labor market which was exacerbated by the 1997 economic recession. In this social and economic setting, body shape and weight status, as human capital, may have gained significant bargaining power in the labor market. Consequently, we propose that Koreans, particularly those who are employed in "stable" jobs (i.e., non-manual and regular jobs), would increasingly engage in intense weight management and reduction activities even when not technically overweight or obese as a means to job security and upward mobility. Using nationally-representative data from the Korean Nutrition and Health Examination Survey (KNHANES), we identify the changing role of weight concerns versus actual body weight in predicting South Korean efforts to lose weight between 2001 (KNHANES-phase 1) and 2007-2009 (phase 4). The patterns were examined by occupation type (manual and non-manual jobs) and status (regular and non-regular jobs). Oaxaca decomposition analysis supported that people's perception of being "fat," rather than actual weight status, was crucial to explaining accelerated weight management efforts in South Korea over the decade (coef. = 0.062 and p-value < .0001 for male with regular work; coef. = 0.031 and p-value = .002 for female with regular work). Occupation status, rather than employment in itself, mattered. Job stability predicted increased effort; the pattern of change through time suggests efforts to invest high levels of effort in appearance positively impacts both employment opportunity and stability.

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

Directory of Open Access Journals (Sweden)

Wenqiong Xue

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 describe ultrasound findings of Kimura's disease arising in the upper extremities. Five patients with Kimura's disease confirmed by surgical resection were retrospectively reviewed by two musculoskeletal radiologists and a pathologist. All six lesions involved the epitrochlear area and appeared as partially (n = 5) or poorly (n = 1) marginated subcutaneous masses with the presence of curvilinear hyperechoic bands intermingled within the hypoechoic components by US. Moderate (n = 4) to severe (n = 2) vascular signals were observed in some proportion of the hyperechoic bands by color Doppler US. The associated findings were the increased echogenicity of surrounding subcutaneous fat (n = 6) and adjacent lymphadenopathy (n = 4). Microscopic examination showed proliferation of lymphoid follicles with prominent germinal centers and intervening fibrosis. In this study, Kimura's disease arising in the upper extremities showed a partially defined hypoechoic subcutaneous mass with internal hyperechoic bands and moderate-to-severe vascularities, increased echogenicity of the surrounding subcutaneous fat and adjacent lymphadenopathy on US. Thus, when these US features are observed in the typical epitrochlear region of an Asian individual, especially if accompanied by peripheral eosinophilia, Kimura's disease should be considered as a possible diagnosis.
Effects of extreme precipitation to the distribution of infectious diseases in Taiwan, 1994-2008.

Directory of Open Access Journals (Sweden)

Mu-Jean Chen

Full Text Available The incidence of extreme precipitation has increased with the exacerbation of worldwide climate disruption. We hypothesize an association between precipitation and the distribution patterns that would affect the endemic burden of 8 infectious diseases in Taiwan, including water- and vector-borne infectious diseases. A database integrating daily precipitation and temperature, along with the infectious disease case registry for all 352 townships in the main island of Taiwan was analysed for the period from 1994 to 2008. Four precipitation levels, 350 mm, were categorized to represent quantitative differences, and their associations with each specific disease was investigated using the Generalized Additive Mixed Model and afterwards mapped on to the Geographical Information System. Daily precipitation levels were significantly correlated with all 8 mandatory-notified infectious diseases in Taiwan. For water-borne infections, extreme torrential precipitation (>350 mm/day was found to result in the highest relative risk for bacillary dysentery and enterovirus infections when compared to ordinary rain (<130 mm/day. Yet, for vector-borne diseases, the relative risk of dengue fever and Japanese encephalitis increased with greater precipitation only up to 350 mm. Differential lag effects following precipitation were statistically associated with increased risk for contracting individual infectious diseases. This study's findings can help health resource sector management better allocate medical resources and be better prepared to deal with infectious disease outbreaks following future extreme precipitation events.

To examine the extent to which weight gain and weight status in the first 2 years of life relate to the risk of neurodevelopmental impairment in extremely preterm infants. In a cohort of 1070 infants born between 23 and 27 weeks' gestation, we examined weight gain from 7-28 days of life (in quartiles) and weight z-score at 12 and 24 months corrected age (in 4 categories: Weight gain in the lowest quartile from 7-28 days was not associated with higher risk of adverse outcomes. Children with a 12-month weight z-score weight z-score weight z-score at 24 months with adverse outcomes were attenuated with exclusion of children with motor impairment. Excluding children who have gross motor impairment appears to eliminate the association of low weight status with neurodevelopmental impairments at 2 years in extremely preterm infants.

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.

Bacterial diarrheal diseases have a high incidence rate during and after flooding episodes. In the Brazilian Amazon, flood extreme events have become more frequent, leading to high incidence rates for infant diarrhea. In this study we aimed to find a statistical association between rainfall, river levels and diarrheal diseases in children under 5, in the river Acre basin, in the State of Acre (Brazil). We also aimed to identify the time-lag and annual season of extreme rainfall and flooding in different cities in the water basin. The results using Tropical Rainfall Measuring Mission (TRMM) Satellite rainfall data show robustness of these estimates against observational stations on-ground. The Pearson coefficient correlation results (highest 0.35) indicate a time-lag, up to 4 days in three of the cities in the water-basin. In addition, a correlation was also tested between monthly accumulated rainfall and the diarrheal incidence during the rainy season (DJF). Correlation results were higher, especially in Acrelândia (0.7) and Brasiléia and Epitaciolândia (0.5). The correlation between water level monthly averages and diarrheal diseases incidence was 0.3 and 0.5 in Brasiléia and Epitaciolândia. The time-lag evidence found in this paper is critical to inform stakeholders, local populations and civil defense authorities about the time available for preventive and adaptation measures between extreme rainfall and flooding events in vulnerable cities. This study was part of a pilot application in the state of Acre of the PULSE-Brazil project (http://www.pulse-brasil.org/tool/), an interface of climate, environmental and health data to support climate adaptation. The next step of this research is to expand the analysis to other climate variables on diarrheal diseases across the whole Brazilian Amazon Basin and estimate the relative risk (RR) of a child getting sick. A statistical model will estimate RR based on the observed values and seasonal forecasts (higher

Cambodia is prone to extreme weather events, especially floods, droughts and typhoons. Climate change is predicted to increase the frequency and intensity of such events. The Cambodian population is highly vulnerable to the impacts of these events due to poverty; malnutrition; agricultural dependence; settlements in flood-prone areas, and public health, governance and technological limitations. Yet little is known about the health impacts of extreme weather events in Cambodia. Given the extremely low adaptive capacity of the population, this is a crucial knowledge gap. A literature review of the health impacts of floods, droughts and typhoons in Cambodia was conducted, with regional and global information reviewed where Cambodia-specific literature was lacking. Water-borne diseases are of particular concern in Cambodia, in the face of extreme weather events and climate change, due to, inter alia, a high pre-existing burden of diseases such as diarrhoeal illness and a lack of improved sanitation infrastructure in rural areas. A time-series analysis under quasi-Poisson distribution was used to evaluate the association between floods and diarrhoeal disease incidence in Cambodian children between 2001 and 2012 in 16 Cambodian provinces. Floods were significantly associated with increased diarrhoeal disease in two provinces, while the analysis conducted suggested a possible protective effect from toilets and piped water. Addressing the specific, local pre-existing vulnerabilities is vital to promoting population health resilience and strengthening adaptive capacity to extreme weather events and climate change in Cambodia.

Seizures can be provoked by systemic diseases associated with metabolic derangements, but the association between liver disease and seizures remains unclear. We performed a retrospective cohort study using inpatient and outpatient claims between 2008 and 2015 from a nationally representative 5% sample of Medicare beneficiaries. The primary exposure variable was cirrhosis, and the secondary exposure was mild, noncirrhotic liver disease. The primary outcome was seizure, and the secondary outcome was status epilepticus. Diagnoses were ascertained using validated International Classification of Diseases, Ninth Edition, Clinical Modification codes. Survival statistics were used to calculate incidence rates, and Cox proportional hazards models were used to examine the association between exposures and outcomes while adjusting for seizure risk factors. Among 1 782 402 beneficiaries, we identified 10 393 (0.6%) beneficiaries with cirrhosis and 19 557 (1.1%) with mild, noncirrhotic liver disease. Individuals with liver disease were older and had more seizure risk factors than those without liver disease. Over 4.6 ± 2.2 years of follow-up, 49 843 (2.8%) individuals were diagnosed with seizures and 25 patients (0.001%) were diagnosed with status epilepticus. Cirrhosis was not associated with seizures (hazard ratio [HR] = 1.1, 95% confidence interval [CI] = 1.0-1.3), but there was an association with status epilepticus (HR = 1.9, 95% CI = 1.3-2.8). Mild liver disease was not associated with a higher risk of seizures (HR = 0.8, 95% CI = 0.6-0.9) or status epilepticus (HR = 1.1, 95% CI = 0.7-1.5). In a large, population-based cohort, we found an association between cirrhosis and status epilepticus, but no overall association between liver disease and seizures.

Maternal periodontal disease is found in pregnancy outcomes. Vitamin D deficiency may play a role in periodontal disease and tooth loss, and insufficient vitamin D status is common among pregnant women. The objective of this study is to examine the relationship between maternal vitamin D status and periodontal disease. A case-control study was conducted. Cases were defined as pregnant women with clinical moderate to severe periodontal disease; controls were pregnant women who were periodontally healthy. Maternal data were chart abstracted and serum was collected between 14 and 26 weeks of gestation. Serum 25-hydroxyvitamin D (25[OH]D) levels were measured using liquid chromatography-tandem mass spectrometry. Median serum 25(OH)D levels and prevalence of vitamin D insufficiency (defined as periodontal disease among women with vitamin D insufficiency was calculated using multivariable logistic regression, adjusting for maternal race, season of blood draw, and other potential confounders. A total of 117 cases were compared to 118 controls. Cases had lower median 25(OH)D levels than controls (59 versus 100 nmol/l; P periodontal disease among women with vitamin D insufficiency was 2.1 (0.99 to 4.5).

The societal and individual burden caused by acute and chronic lower extremity venous disease is considerable. In the past several decades, minimally invasive endovascular interventions have been developed to reduce thrombus burden in the setting of acute deep venous thrombosis to prevent both short- and long-term morbidity and to recanalize chronically occluded or stenosed postthrombotic or nonthrombotic veins in symptomatic patients. This state-of-the-art review provides an overview of the techniques and challenges, rationale, patient selection criteria, complications, postinterventional care, and outcomes data for endovascular intervention in the setting of acute and chronic lower extremity deep venous disease.

Examine whether unhealthy and extreme weight control behaviors (WCBs) mediate the relationship between youth weight status and disease-specific health-related quality of life (HRQOL) in treatment-seeking youth who are overweight and obese (OV/OB). 82 youth 10-17 years of age who were OV/OB and attending an outpatient obesity-related medical appointment completed measures assessing unhealthy and extreme WCBs and disease-specific HRQOL. Parents completed a demographic questionnaire and medical staff measured youth height and weight. Regression analyses revealed that unhealthy WCBs mediated the associations between youth weight status and emotional and social avoidance disease-specific HRQOL, such that higher body mass index (BMI) predicted unhealthy WCBs, which were ultimately associated with poorer emotional and social HRQOL. Mediation analyses were not significant for total, physical, teasing/marginalization, and positive attributes disease-specific HRQOL. In addition, extreme WCBs did not mediate the association between youth weight status and any subscales of the disease-specific HRQOL measure. Weight status is an important predictor of disease-specific HRQOL in OV/OB youth; however, the association with emotional and social HRQOL is partially accounted for by youth engagement in unhealthy WCBs. Clinicians and researchers should assess WCBs and further research should explore and evaluate appropriate intervention strategies to address unhealthy WCBs in pediatric weight management prevention and treatment efforts.

To evaluate the efficacy of endovascular management of lower extremity deep vein thrombosis (DVT) in patients with malignant disease. Between January 2002 and January 2008, six consecutive patients (5 male and 1 female, mean age-65 years) with lower extremity DVT and malignant disease underwent endovascular management. The duration of symptoms lasted 4-120 days (mean-31 days; 20 days or less in four patients and more than 20 days in two). A catheter-directed thrombolysis was performed via the ipsilateral popliteal vein or common femoral vein, used alone or combined with a percutaneous mechanical thrombectomy. Angioplasty or stent placement was performed in residual stenosis or occlusion of the vein. The follow-up period lasted 1-14 months (mean 7.6 months) and was performed via a color Doppler ultrasonography or computed tomographic venography. Technical success and relief from symptoms was achieved within two days was achieved in five patients. Minor hemorrhagic complications occurred in two cases: hematuria and a hematoma at the puncture site. Upon follow-up, a recurrent DVT occurred in three patients as well as a patent venous flow in two. One patient died within 1 month due to a metastatic mediastinal lymphadenopathy. Endovascular management of the lower extremity DVT is effective for quickly eliminating a thrombus, relieving symptoms, and decreasing hemorrhagic complications in patients with malignant disease

OBJECTIVES: Vitamin D deficiency is common among persons with chronic obstructive pulmonary disease (COPD). Whether vitamin D affects the development and deterioration of COPD or is a consequence of the disease lacks clarity. We investigated the association between vitamin D status and prevalent...... and incident COPD in the general population. METHODS: We included a total of 12,041 individuals from three general population studies conducted in 1993-94, 1999-2001, and 2006-2008, respectively, with vitamin D measurements. Information on COPD was obtained from the Danish National Patient Register...... and The Danish Registry of Causes of Death. RESULTS: There were 85 prevalent and 463 incident cases of COPD (median follow-up 9.7 years). We found a statistically significant inverse association between vitamin D status and prevalent COPD with odds ratio = 0.89 (95% confidence interval, CI: 0.79, 1...

The states of being are conventionally defined by the simultaneous occurrence of behavioral, neurophysiological and autonomic descriptors. State dissociation disorders are due to the intrusion of features typical of a different state into an ongoing state. Disorders related to these conditions are classified according to the ongoing main state and comprise: 1) Dissociation from prevailing wakefulness as seen in hypnagogic or hypnopompic hallucinations, automatic behaviors, sleep drunkenness, cataplexy and sleep paralysis 2) Dissociation from rapid eye movement (REM) sleep as seen in REM sleep behavior disorder and lucid dreaming and 3) Dissociation from NREM sleep as seen in the disorders of arousal. The extreme expression of states dissociation is characterized by the asynchronous occurrence of the various components of the different states that prevents the recognition of any state of being. This condition has been named status dissociatus. According to the underlying disorders/diseases and to their severity, among status dissociatus we may recognize disorders in which such an extreme dissociation occurs only at night time or intermittently (i.e., autoimmune encephalopathies, narcolepsy type 1 and IgLON5 parasomnia), and others in which it occurs nearly continuously with complete loss of any conventionally defined state of being, and of the circadian pattern (agrypnia excitata). Here, we render a comprehensive review of all diseases/disorders associated with state dissociation and status dissociatus and propose a critical classification of this complex scenario.

Outcome disparities associated with lower extremity bypass (LEB) for peripheral artery disease (PAD) have been identified but are poorly understood. Marital status may affect outcomes through factors related to health risk behaviors, adherence, and access to care but has not been characterized as a predictor of surgical outcomes and is often omitted from administrative data sets. We evaluated associations between marital status and vein graft patency following LEB using multivariable models adjusting for established risk factors. Consecutive patients undergoing autogenous LEB for PAD were identified and analyzed. Survival analysis and Cox proportional hazards models were used to evaluate patency stratified by marital status (married versus single, divorced, or widow[er]) adjusting for demographic, comorbidity, and anatomic factors in multivariable models. Seventy-three participants who underwent 79 autogenous vein LEB had complete data and were analyzed. Forty-three patients (58.9%) were married, and 30 (41.1%) were unmarried. Compared with unmarried patients, married patients were older at the time of their bypass procedure (67.3 ± 10.8 years vs. 62.2 ± 10.6 years; P = 0.05). Married patients also had a lower prevalence of female gender (11.6% vs. 33.3%; P = 0.02). Diabetes, hypertension, hyperlipidemia, and smoking were common among both married and unmarried patients. Minimum great saphenous vein conduit diameters were larger in married versus unmarried patients (2.82 ± 0.57 mm vs. 2.52 ± 0.65 mm; P = 0.04). Twenty-four-month primary patency was 66% for married versus 38% for unmarried patients. In a multivariable proportional hazards model adjusting for proximal and distal graft inflow/outflow, medications, gender, age, race, smoking, diabetes, and minimum vein graft diameter, married status was associated with superior primary patency (hazard ratio [HR] = 0.33; 95% confidence limits [0.11, 0.99]; P = 0.05); other predictive covariates

Full Text Available We determined the association between vitamin D status as 25hydroxyvitamin D [25(OHD] and disease activity in a cohort of 201 Crohn’s Disease (CD patients in Saskatoon, Canada over three years. The association between high-sensitivity C-reactive protein (hs-CRP and 25(OHD and several disease predictors were evaluated by the generalized estimating equation (GEE over three time-point measurements. A GEE binary logistic regression test was used to evaluate the association between vitamin D status and the Harvey-Bradshaw Index (HBI. The deficient vitamin D group (≤29 nmol/L had significantly higher mean hs-CRP levels compared with the three other categories of vitamin D status (p < 0.05. CRP was significantly lower in all of the other groups compared with the vitamin D-deficient group, which had Coef. = 12.8 units lower (95% CI −19.8, −5.8, Coef. 7.85 units (95% CI −14.9, −0.7, Coef. 9.87 units (95% CI −17.6, −2.0 for the vitamin D insufficient, adequate, and optimal groups, respectively. The vitamin D status was associated with the HBI active disease category. However, the difference in the odds ratio compared with the reference category of deficient vitamin D category was only significant in the insufficient category (odds ratio = 3.45, p = 0.03, 95% CI 1.0, 10.8. Vitamin D status was inversely associated with indicators of disease activity in Crohn’s disease, particularly with the objective measures of inflammation.

"Médecins du Monde" healthcare centers receive individuals living in extremely precarious conditions for primary health care; 94% of these are foreigners. These medical consultations are an opportunity to discuss their serological status and to offer them screening tests. Two standardized questionnaires were implemented in all healthcare centers in 2000. The medical record covers knowledge of HIV and hepatitis B and C status. 41,033 consultations were given in 2012 in the 20 healthcare centers, for 23,181 patients. Only 29% of the patients knew their hepatitis status and 35% their HIV status. 42% of French patients were unaware of their HIV status compared to 67% of foreign patients. The lack of knowledge of foreign patients' HIV status was more frequent among men and in age classes60 years of age. Patients from non-EU Europe, the Middle East, and Asia were significantly more likely to be unaware of their HIV status compared to people from Sub-Saharan Africa and Oceania/America. The rate of foreigners not having undergone screening remained stable, regardless of the duration of residence in France. These results highlight the need to develop specific prevention projects among immigrant populations in precarious situations. Copyright © 2015 Elsevier Masson SAS. All rights reserved.
Hepatic tuberculosis presenting with extreme hyperferritinemia masquerading as adult-onset Still’s disease: a case report

Directory of Open Access Journals (Sweden)

Manoj Edirisooriya

2012-07-01

Full Text Available Abstract Introduction Isolated hepatic tuberculosis is an uncommon manifestation of one of the most common infections worldwide, caused by Mycobacterium tuberculosis. Extremely high serum ferritin, which is regarded as a marker of adult onset Still’s disease, has not been observed in patients with tuberculosis of the liver. We report a case of hepatic tuberculosis who presented with clinical criteria of adult-onset Still’s disease and extreme hyperferritinemia, which posed a diagnostic confusion. Case presentation Our patient was a 48-year-old Sri Lankan man who presented with fever, polyarthralgia and a generalized skin rash of three months duration. He had marked constitutional symptoms, oral ulcers, hair loss, anemia and hepatomegaly. Laboratory investigations disclosed an inflammatory syndrome, evidence of hepatic dysfunction, bone marrow suppression and a raised serum ferritin level of 34,674 ng/ml. A rapidly deteriorating course of illness prompted treatment based on a presumptive diagnosis of adult-onset Still’s disease until liver histology was available. The patient died of sepsis followed by multi-organ dysfunction. Later, the liver histology revealed tuberculosis. Conclusion Extrapulmonary tuberculosis, although well known to present with peculiar manifestations, has not been reported to be associated with extremely high levels of serum ferritin in immunocompetent individuals. Isolated hepatic tuberculosis presenting with clinical criteria of adult-onset Still’s disease is remarkable. Since tuberculosis remains a potentially curable disease, an awareness of its’ protean manifestations is essential.

We document significant worldwide weather anomalies that affected agriculture and vector-borne disease outbreaks during the 2010-2012 period. We utilized 2000-2012 vegetation index and land surface temperature data from NASA's satellite-based Moderate Resolution Imaging Spectroradiometer (MODIS) to map the magnitude and extent of these anomalies for diverse regions including the continental United States, Russia, East Africa, Southern Africa, and Australia. We demonstrate that shifts in temperature and/or precipitation have significant impacts on vegetation patterns with attendant consequences for agriculture and public health. Weather extremes resulted in excessive rainfall and flooding as well as severe drought, which caused,10 to 80% variation in major agricultural commodity production (including wheat, corn, cotton, sorghum) and created exceptional conditions for extensive mosquito-borne disease outbreaks of dengue, Rift Valley fever, Murray Valley encephalitis, and West Nile virus disease. Analysis of MODIS data provided a standardized method for quantifying the extreme weather anomalies observed during this period. Assessments of land surface conditions from satellite-based systems such as MODIS can be a valuable tool in national, regional, and global weather impact determinations.

Objective: To compare the difference between multi-slice spiral CT angiography (MSCTA) and color doppler ultrasound in diagnosis of arteriosclerotic occlusive disease of lower extremity. Methods: Patients with arteriosclerosis occlusion were assessed by color doppler ultrasound, multi-slice spiral CT angiography and digital subtraction angiography (DSA). The image information of color doppler ultrasound and MSCTA were compared with that of DSA. Results: Color doppler ultrasound showed the anatomical shape and hemodynamics of the arteries of lower extremity. The sensitivity, specificity, and accuracy for diagnosis arteriosclerotic occlusive disease of lower extremity were 88.04%, 90.69% and 88.77% respectively. MSCTA showed the three dimensional structure of the arteries of lower extremity as well as the collateral arteries and the distal arterials. The sensitivity, specificity and accuracy of MSCTA were 97.69%, 96.90% and 97.66%, respectively. Conclusion: Multi-slice spiral CT angiography is an ideal imaging method for the diagnosis of arteriosclerotic occlusive disease of lower extremity. (authors)

The metabolic changes compounded by anorexia associated with chronic liver disease adversely affect growth in children. In many cases, this requires the administration of artificial nutritional support. It is important in this group of patients that those who are becoming nutritionally depleted are identified quickly and in those receiving artificial nutritional support, the effectiveness is monitored. The current review is an examination of methods available to assess nutritional status. These include anthropometry, methods available in the laboratory and a selection of less commonly used methods undergoing evaluation at research level. A brief discussion accompanies each technique, outlining the limitations of its use in children with chronic liver disease. The review concludes with an outline of how nutritional status should be assessed in this group of children, and suggests further research.

This study explored whether there is any change of periodontal disease status during and after pregnancy. We also examined whether the change is different between females with a history of gestational diabetes mellitus (GDM) and females without GDM during pregnancy. A follow-up study was conducted at Woman's Hospital, Baton Rouge, Louisiana. Thirty-nine females who were previously enrolled in a case-control study during pregnancy were followed an average of 22 months postpartum. Periodontal status was assessed through dental examinations performed both during and after pregnancy. Clinical periodontal parameters included bleeding on probing (BOP), mean probing depth (PD), and mean clinical attachment level (CAL). Periodontitis was defined as the presence of ≥1 sites exhibiting PD ≥4 mm or CAL ≥4 mm. We used generalized estimating equation analysis to examine the change of periodontal status. Mean number and percentage of sites with BOP decreased from 10.7 ± 11.6 (mean ± SD) and 6.5% ± 7.0% during pregnancy to 7.1 ± 8.8 and 4.3% ± 5.3% at 22 months postpartum (P periodontitis decreased from 66.7% to 33.3% (P periodontal status between females with GDM and females without GDM during pregnancy. Pregnancy may be associated with an increased risk of periodontal disease. The association is not different between females with GDM and females without GDM during pregnancy.

Diabetic foot disease is associated with major morbidity, mortality, costs, and reduction of a person's quality of life. Investigating the epidemiology of diabetic foot disease is the backbone of diabetic foot research and clinical practice, yet the full burden of diabetic foot disease in Australia is unknown. This study aims to describe the protocol for a systematic review of the epidemiology of diabetic foot disease and diabetes-related lower-extremity amputation in Australia. The systematic review will be performed according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. PubMed and EMBASE will be searched for publications in any language and without restrictions to date. Two independent investigators will screen publications for eligibility, with publications reporting Australian population-based incidence or prevalence of diabetic foot disease or diabetes-related lower-extremity amputation to be included. Additionally, a forward literature search will be performed in Google Scholar, and a grey literature search will be performed to identify government publications. Quality assessment will be performed using customised checklists. The summary statistic used for each study will be an incidence or prevalence proportion of diabetic foot disease or diabetes-related lower-extremity amputation. The standard error for each proportion will be calculated. A meta-analysis will be performed when three or more publications of adequate quality, reporting on similar outcomes and in similar populations, are identified. The results of this systematic review can be used to adequately inform stakeholders in the field of diabetic foot disease on the extent of the problem in incidence and prevalence of diabetic foot disease in Australia, and to help guide appropriate use of resources to reduce the burden of this disease.

Anna Kawicka

2015-01-01

Full Text Available 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.

[Purpose] The purpose of this study was to examine the effects of interactive metronome training on the postural stability and upper extremity function of an individual with Parkinson's disease. [Subject and Methods] The participant of this case study was a 75-year-old female with Parkinson's disease diagnosed 7 years prior. This study was a single-subject research with an A-B-A design. She received IM training during the treatment phase (B phase) for 40 minutes per session. She was assessed pretest and posttest using the Berg balance scale and Wolf motor function test, and at baseline and the treatment phase using the measured box-and-block test and a Tetrax system. [Results] After training, the patient's static and dynamic balance, functional activity, and performance time of the upper extremity improved. Interactive metronome therapy improved the manual dexterity of both hands. Interactive metronome therapy also improved the limit of stability of the Parkinson's disease. [Conclusion] Though a case study, the results of this study suggest that IM therapy is effective at restoring the postural stability and upper extremity function of patients with Parkinson's disease.

Recent weather extremes and impacts on agricultural production and vector-borne disease outbreak patterns.

Directory of Open Access Journals (Sweden)

Assaf Anyamba

Full Text Available We document significant worldwide weather anomalies that affected agriculture and vector-borne disease outbreaks during the 2010-2012 period. We utilized 2000-2012 vegetation index and land surface temperature data from NASA's satellite-based Moderate Resolution Imaging Spectroradiometer (MODIS to map the magnitude and extent of these anomalies for diverse regions including the continental United States, Russia, East Africa, Southern Africa, and Australia. We demonstrate that shifts in temperature and/or precipitation have significant impacts on vegetation patterns with attendant consequences for agriculture and public health. Weather extremes resulted in excessive rainfall and flooding as well as severe drought, which caused ∼10 to 80% variation in major agricultural commodity production (including wheat, corn, cotton, sorghum and created exceptional conditions for extensive mosquito-borne disease outbreaks of dengue, Rift Valley fever, Murray Valley encephalitis, and West Nile virus disease. Analysis of MODIS data provided a standardized method for quantifying the extreme weather anomalies observed during this period. Assessments of land surface conditions from satellite-based systems such as MODIS can be a valuable tool in national, regional, and global weather impact determinations.

To review the available scientific literature about the effects of nutritional status on the multiple sclerosis disease. A systematic review of the scientific literature in the Medline (PubMed), Scopus, Cochrane Library and Web of Science databases through November 2016. Search equation: ("Multiple Sclerosis"[Mesh] OR "Multiple Sclerosis"[Title/Abstract] OR "Disseminated Sclerosis"[Title/Abstract] OR "Multiple Sclerosis Acute Fulminating"[Title/Abstract]) AND ("Nutritional Status"[Mesh] OR "Nutritional Status"[Title/Abstract] OR "Nutrition Status"[Title/Abstract]). The quality of the selected articles was discussed using the STROBE questionnaire. The search was completed through experts inquiry and additional review of the bibliographic references included in the selected papers. The concordance between authors (Kappa index) had to be higher than 80% for inclusion in this review. Of the 160 references recovered, after applying inclusion and exclusion criteria, 29 articles were selected for review. Concordance between evaluators was 100.00%. The most studies established vitamin D levels. Others focused their research on finding out which nutrient deficits might be related to the multiple sclerosis development. Vitamin D may influence multiple sclerosis improvement. Sunlight and physical activity would be important factors, with nutritional status, in the course of this disease. It is necessary to produce new specific works that will delve into the subject to find out more about the relationship between nutritional status and multiple sclerosis.

2014-03-01

To compare employee overall well-being to chronic disease status, which has a long-established relationship to productivity, as relative contributors to on-the-job productivity. Data from two annual surveys of three companies were used in longitudinal analyses of well-being as a predictor of productivity level and productivity change among 2629 employees with diabetes or without any chronic conditions. Well-being was the most significant predictor of productivity cross-sectionally in a model that included disease status and demographic characteristics. Longitudinally, changes in well-being contributed to changes in productivity above and beyond what could be explained by the presence of chronic disease or other fixed characteristics. These findings support the use of well-being as the broader framework for understanding, explaining, and improving employee productivity in both the healthy and those with disease.

Being unmarried is associated with decreased survival in the general population. Whether married, divorced, separated, widowed, or never-married status affects outcomes in patients with cardiovascular disease has not been well characterized. A prospective cohort (inception period 2003-2015) of 6051 patients (mean age 63 years, 64% male, 23% black) undergoing cardiac catheterization for suspected or confirmed coronary artery disease was followed for a median of 3.7 years (interquartile range: 1.7-6.7 years). Marital status was stratified as married (n=4088) versus unmarried (n=1963), which included those who were never married (n=451), divorced or separated (n=842), or widowed (n=670). The relationship between marital status and primary outcome of cardiovascular death and myocardial infarction was examined using Cox regression models adjusted for clinical characteristics. There were 1085 (18%) deaths from all causes, 688 (11%) cardiovascular-related deaths, and 272 (4.5%) incident myocardial infarction events. Compared with married participants, being unmarried was associated with higher risk of all-cause mortality (hazard ratio [HR]: 1.24; 95% confidence interval [CI], 1.06-1.47), cardiovascular death (HR: 1.45; 95% CI, 1.18-1.78), and cardiovascular death or myocardial infarction (HR: 1.52; 95% CI, 1.27-1.83). Compared with married participants, the increase in cardiovascular death or myocardial infarction was similar for the participants who were divorced or separated (HR: 1.41; 95% CI, 1.10-1.81), widowed (HR: 1.71; 95% CI, 1.32-2.20), or never married (HR: 1.40; 95% CI, 0.97-2.03). The findings persisted after adjustment for medications and other socioeconomic factors. Marital status is independently associated with cardiovascular outcomes in patients with or at high risk of cardiovascular disease, with higher mortality in the unmarried population. The mechanisms responsible for this increased risk require further study. © 2017 The Authors. Published on

Full Text Available Objective. To investigate the relationship between alcohol consumption and diabetic lower extremity arterial disease (LEAD in hospitalized patients with type 2 diabetes mellitus (T2DM. Methods. We evaluated 138 hospitalized patients with T2DM who consumed alcohol and 833 who did not. We used propensity score matching to reduce the confounding bias between groups. Additionally, a logistic regression analysis was performed with the matched data to evaluate the LEAD risk. Results. In total, 119 pairs of patients who did and did not consume alcohol were matched. According to the logistic regression analysis, patients who consumed >8 U of alcohol/day had a higher risk of LEAD (odds ratio (OR: 6.35, 95% confidence interval (CI: 1.78–22.65 than patients who did not consume alcohol. Additionally, after adjusting for age, gender, region, occupation, smoking status, body mass index, weight change, and duration of diabetes, the OR of peripheral artery disease after >20 years of alcohol consumption was 3.48 (95% CI: 1.09–11.15. Furthermore, we observed a significant dose-response relationship between alcohol consumption and LEAD. Conclusions. Alcohol consumption may be a risk factor of LEAD in patients with T2DM. Patients with T2DM should be advised to stop drinking, to prevent the onset of LEAD.
Socioeconomic status and risk factors for cardiovascular disease: Impact of dietary mediators.

It is well known that cardiovascular disease is the leading cause of mortality in the western societies. A number of risk factors such as family history, diabetes, hypertension, obesity, diabetes, smoking and physical inactivity are responsible for a significant proportion of the overall cardiovascular risk. Interestingly, recent data suggest there is a gradient in the incidence, morbidity and mortality of cardiovascular disease across the spectrum of socioeconomic status, as this is defined by educational level, occupation or income. Additionally, dietary mediators seem to play significant role in the pathogenesis of cardiovascular disease, mediating some of the discrepancies in atherosclerosis among different socioeconomic layers. Therefore, in the present article, we aim to review the association between socioeconomic status and cardiovascular disease risk factors and the role of different dietary mediators.

Patients managed in European or North American cancer centres have a variety of ethnic backgrounds and primary languages. To gain insight into the impact of ethnic origin, we have investigated understanding of disease status and quality of life (QoL) for 202 patients. Patients completed questionnaires in their first language (52 English, 50 Chinese, 50 Italian, 50 Spanish or Portuguese), including the Functional Assessment of Cancer Therapy - General (FACT-G) QoL instrument, questions about disease status, expectations of cure and the language and/or type of interpretation used at initial consultation. Physicians also evaluated their status of disease and expectation of cure, and performance status was estimated by a trained health professional. The initial consultation was usually provided in English (except for 32% of Chinese-speaking patients); interpretation was provided by a family member for 34% of patients with limited English proficiency (LEP) and by a bilingual member of staff for 21%. Patients underestimated their extent of disease and overestimated their probability of cure (P=0.001 and cultural differences is important for optimal management of patients with cancer.

Fry, D E; Marek, J M; Langsfeld, M

1998-06-01

Infections in the lower extremity of the patient with ischemia can cover a broad spectrum of different diseases. An understanding of the particular pathophysiologic circumstances in the ischemic extremity can be of great value in understanding the natural history of the disease and the potential complications that may occur. Optimizing blood flow to the extremity by using revascularization techniques is important for any patient with an ischemic lower extremity complicated by infection or ulceration. Infections in the ischemic lower extremity require local débridement and systemic antibiotics. For severe infections, such as necrotizing fasciitis or the fetid foot, more extensive local débridement and even amputation may be required. Fundamentals of managing prosthetic graft infection require removing the infected prosthesis, local wound débridement, and systemic antibiotics while attempting to preserve viability of the lower extremity using autogenous graft reconstruction.

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.

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.

Cardiovascular disease is the leading cause of morbidity, mortality and disability in Portugal. Socioeconomic level is known to influence health status but there is scant evidence on socioeconomic inequalities in cardiovascular disease in Portugal. To analyze the distribution of cardiovascular disease in the Portuguese population according to socioeconomic status. We conducted a cross-sectional study using data from the fourth National Health Survey on a representative sample of the Portuguese population. Socioeconomic inequalities in cardiovascular disease, risk factors and number of medical visits were analyzed using odds ratios according to socioeconomic status (household equivalent income) in the adult population (35-74 years). Comparisons focused on the top and bottom 50% and 10% of household income distribution. Of the 21 807 individuals included, 53.3% were female, and mean age was 54 ± 11 years. Cardiovascular disease, stroke, ischemic heart disease, hypertension, diabetes, obesity and physical inactivity were associated with lower socioeconomic status, while smoking was associated with higher status; number of medical visits and psychological distress showed no association. When present, inequality was greater at the extremes of income distribution. The results reveal an association between morbidity, lifestyle and socioeconomic status. They also suggest that besides improved access to effective medical intervention, there is a need for a comprehensive strategy for health promotion and disease prevention that takes account of individual, cultural and socioeconomic characteristics.

Until now, there has been no study on the relationship between the calcification of the lower extremity arteries and significant coronary arterial disease (CAD). To evaluate whether lower extremity calcium scores (LECS) are associated with CAD and whether this can predict multivessel-CAD in patients with peripheral arterial disease (PAD). We retrospectively enrolled 103 PAD patients without cardiac symptoms or known CAD. All patients underwent cardiac computed tomography (CT) and lower extremity CT within 1 month and were categorized as nonsignificant CAD, single-CAD, or multivessel-CAD. The coronary calcium scores (CCS) were quantitatively measured according to the Agatston method and LECS were semi-quantitatively measured according to the presence of lower extremity calcification in the segment. The extent of CAD was evaluated according to the presence of ≥ 50% luminal diameter stenosis in the segment of CAD. LECS in multivessel-CAD were significantly higher than those in nonsignificant CAD (10.0 ± 5.8 versus 4.0 ± 3.1, P < 0.001). LECS significantly correlated with CCS (r = 0.831, P < 0.001) and the extent of CAD (r = 0.631, P < 0.001). Multivariate regression analysis demonstrated LECS and log-transformed CCS were independent predictors for multivessel-CAD. In receiver operating characteristic curve analysis, the diagnostic performance of LECS was 0.807 (95% confidence interval = 0.724-0.891, P < 0.001) for predicting multivessel-CAD. Peripheral arterial calcification is significantly correlated with CAD extent in patients with PAD. Peripheral arterial calcification can be a useful marker for predicting multivessel-CAD

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.

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 awareness, treatment and prevention of chronic diseases are generally poor among the elderly population of China, whereas the prevention and control of chronic diseases in elderly veteran communities have been ongoing for more than 30 years. Therefore, investigating the awareness status of chronic disabling neurological diseases (CDND) and common chronic diseases (CCD) among elderly veterans may provide references for related programs among the elderly in the general population. A cross-sectional survey was conducted among veterans ≥60 years old in veteran communities in Beijing. The awareness of preventive strategies against dementia, Alzheimer's disease (AD), Parkinson's disease (PD), sleep disorders, cerebrovascular disease (CVD) and CCD such as hypertension, and the approaches used to access this information, including media, word of mouth (verbal communication among the elderly) and health care professionals, were investigated via face-to-face interviews. The awareness rates for CCD and CVD were approximately 100%, but that for AD was the lowest at word-of-mouth peer education.

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.

Limited evidence is available for the effects of extreme temperatures on cause-specific cardiovascular mortality in China. We collected data from Beijing and Shanghai, China, during 2007-2009, including the daily mortality of cardiovascular disease, cerebrovascular disease, ischemic heart disease and hypertensive disease, as well as air pollution concentrations and weather conditions. We used Poisson regression with a distributed lag non-linear model to examine the effects of extremely high and low ambient temperatures on cause-specific cardiovascular mortality. For all cause-specific cardiovascular mortality, Beijing had stronger cold and hot effects than those in Shanghai. The cold effects on cause-specific cardiovascular mortality reached the strongest at lag 0-27, while the hot effects reached the strongest at lag 0-14. The effects of extremely low and high temperatures differed by mortality types in the two cities. Hypertensive disease in Beijing was particularly susceptible to both extremely high and low temperatures; while for Shanghai, people with ischemic heart disease showed the greatest relative risk (RRs = 1.16, 95% CI: 1.03, 1.34) to extremely low temperature. People with hypertensive disease were particularly susceptible to extremely low and high temperatures in Beijing. People with ischemic heart disease in Shanghai showed greater susceptibility to extremely cold days.

We present 2 cases of teenager males presented with burning pain in extremities and turned out to be cases of Fabry disease.The purpose of presenting this case is to highlight the fact that suspicion of Fabry disease in patients presenting with these symptoms will lead to early diagnosis and treatment of this condition before occurrences of complications. A 14-year-old male presented with severe burning pain in both hands and feet since last 4 yrs which persisted despite consumption of painkillers and becoming more disabling and without having any family history for such condition. On general examination patient had small reddish coloured lesions around the umbilicus, appearing like angiokeratomas. Skin biopsy confirmed the lesion. On enzyme assay his alpha galactosidase activity found to be '0' nmol/hr/mg of protein, confirming his diagnosis. Patient's creatinine and 2 D ECHO were normal and urine had 1+ proteinuria. Patient started on carbamazepine tablets for pain and referred to higher centre for genetic diagnosis and enzyme replacement therapy. CASE REPORT 2: An 18-year-old male referred to our hospital by general practitioner for fatigue and pedal oedema with deranged renal function tests. On history taking patient gave history of severe burning pain in both hands and feet since age of 9 yrs. Patient's general examination revealed hypertension with pallor, pedal oedema along with angiokeratomas in bathing suit distribution. Patient's ultrasonography of kidney revealed bilaterally normal sized kidneys with altered echotexture and urine examination showed fine granular foamy cells with sub nephrotic range proteinuria. 2 D ECHO revealed concentric left ventricular hypertrophy. Skin biopsy report supported the diagnosis of Fabry disease. Patient advised to undergo renal biopsy to confirm Fabry nephropathy but patient denied any further diagnostic workup for nephropathy or Fabry disease. Patient started on conservative treatment and carbamazepine in renal dose

The primary purpose of this scoping review was to describe the nature and extent of the published research that assesses the relationship between psychological features and patient-reported outcome following surgery or rehabilitation of upper extremity disease or injury. Twenty-two included studies were examined for quantitative study design, outcome measure, inclusion/exclusion criteria, follow-up and recruitment strategy. Patient population and psychological assessment tools were examined for validity. Twenty-two studies met the inclusion criteria for this study. Only 7 of the 22 studies were longitudinal and the rest were cross sectional studies. Depression was the most common psychological status of interest and was included in 17 studies. Pain catastrophizing was the psychological status of interest in 5 of the studies. Four studies considered anxiety, 3 considered pain anxiety, 3 considered distress, 2 considered coping, 2 considered catastrophic thinking, and 2 considered fear avoidance beliefs. The majority of studies in this review were cross-sectional studies. Cross-sectional studies may not provide conclusive information about cause-and-effect relationships. This review encourages clinicians to be mindful of the psychological implications found in rehabilitation of individuals with upper extremity disease or injury along with being cognizant of choosing appropriate measurement tools that best represent each patient's characteristics and diagnoses. The nature of the research addressing psychological factors affecting outcomes after hand injury focus on negative traits and have limited strength to suggest causation as most have used cross-sectional designs. Stronger longitudinal designs and consideration of positive traits are needed in future studies. Copyright © 2017. Published by Elsevier Inc.
Current status of indications for surgery in peptic ulcer disease.

The eradication of Helicobacter pylori in patients with peptic ulcer disease has greatly diminished the need for antiulcer surgery. However, in societies where such drug therapy is considered too expensive and because occasional patients remain refractory to optimal medical therapy, elective surgery for duodenal ulcer disease is still carried out. If the required expertise is available, it can be undertaken laparoscopically. The advent of endoscopic therapies such as heater probe therapy and injection sclerotherapy has also greatly diminished the need for emergency surgery in bleeding peptic ulcer disease. Once again, however, when such therapy fails surgery is still indicated. Even with perforated peptic ulcer disease the role of surgery has receded somewhat, but here not because of changes in drug therapy. Nonoperative management of perforation is indicated in fit patients if the diagnosis is in doubt, in any patient when surgical facilities are unavailable (e.g., remote geographic areas, on board ship), or when a patient is extremely ill either because of co-morbidity or late presentation of the disease. Operation should be considered in all patients when the perforation is established to be unsealed, particularly after

Pulmonary arterial hypertension (PAH) is a rare disease. Although muscle strength, exercise capacity, quality of life, and activities of daily living of patients with PAH are affected, it is not known how they are affected by disease severity. The purpose of the present study was to investigate effects of disease severity on upper extremity muscle strength, exercise capacity, and performance of activities of daily living in patients with PAH. Twenty-five patients with disease severity classified according to the New York Heart Association (NYHA) as functional class II (n=14) or class III (n=11) were included in the study. Upper-extremity exercise capacity and limitations in performing activities of daily living were assessed with 6-minute pegboard and ring test (6PBRT) and the Milliken activities of daily living scale (MAS), respectively. Shoulder flexion, elbow extension, elbow flexion muscle strength, and handgrip strength were measured with dynamometer. There were no significant differences in age, gender, body mass index, or mean pulmonary artery pressure between groups (p>0.05). The 6PBRT, MAS, and elbow flexion (right) and grip strength (right and left) results were significantly lower in NYHA III group than in NYHA II group (p=0.004, p=0.002, p=0.043, p=0.002 and p=0.003, respectively). There was no significant difference in shoulder flexion, elbow flexion (left), or elbow extension between groups (p>0.05). Results suggest that upper extremity exercise capacity, elbow flexion muscle strength (right), and handgrip strength decrease and that limitations in activities of daily living grow as disease severity increases in patients with PAH. When planning rehabilitation programs, disease severity should be considered and evaluations and treatments for the upper extremities should be included.

Quadriceps weakness seems to be a hallmark in adult persons with severe haemophilia (PWH). The purpose of this study was to compare PWH and non-haemophilic controls in different age stages with reference to joint status and quadriceps strength. Further aims were to examine the extent of strength-specific inter-extremity-difference (IED) and the prevalence of abnormal IED (AIED). A total of 106 adults with severe haemophilia (H) and 80 controls (C) had undergone an orthopaedic examination for classification of knee and ankle status using the WFH score. Quadriceps strength was evaluated unilaterally as well as bilaterally with a knee extensor device. Each group was divided into four age-related subgroups (HA/CA: 18-29, HB/CB: 30-39, HC/CC: 40-49, HD/CD: 50-70; in years). H presented a worse knee and ankle status than C indicated by higher WFH scores (P age-matched subgroups only HB showed higher knee scores than CB (P age-matched controls (P age in H. We discovered an AIED in 35% of H. These findings highlight the importance for the early implementation of preventive and rehabilitative muscle training programmes in the comprehensive treatment of PWH. © 2012 Blackwell Publishing Ltd.

As a result of ischaemia/reperfusion, massive generation of reactive oxygen species occurs, followed by decreased activity of antioxidant enzymes. Extremely low frequency electromagnetic fields (ELF-EMF) can modulate oxidative stress, but there are no clinical antioxidant studies in brain stroke patients. The aim of our study was to investigate the effect of ELF-EMF on clinical and antioxidant status in post-stroke patients. Fifty-seven patients were divided into two groups: ELF-EMF and non-ELF-EMF. Both groups underwent the same 4-week rehabilitation program. Additionally, the ELF-EMF group was exposed to an ELF-EMF field of 40 Hz, 7 mT for 15 min/day for 4 weeks (5 days a week). The activity of catalase and superoxide dismutase was measured in hemolysates, and total antioxidant status (TAS) determined in plasma. Functional status was assessed before and after the series of treatments using Activities of Daily Living (ADL), Mini-Mental State Examination (MMSE), and Geriatric Depression Scale (GDS). Applied ELF-EMF significantly increased enzymatic antioxidant activity; however, TAS levels did not change in either group. Results show that ELF-EMF induced a significant improvement in functional (ADL) and mental (MMSE, GDS) status. Clinical parameters had positive correlation with the level of enzymatic antioxidant protection. Bioelectromagnetics. 38:386-396, 2017. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

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.

In an extremely rare setting, this disease may get complicated by the development of squamous cell carcinoma. We report this occurrence in an 18-year-old girl to review the currently forgotten status of donovanosis amongst the STDs and the poor outcome of the disease if left untreated.

Extreme learning machines have gained a lot of attention by the machine learning community because of its interesting properties and computational advantages. With the increase in collection of information nowadays, many sources of data have missing information making statistical analysis harder or unfeasible. In this paper, we present a new model, coined spatial extreme learning machine, that combine spatial modeling with extreme learning machines keeping the nice properties of both methodologies and making it very flexible and robust. As explained throughout the text, the spatial extreme learning machines have many advantages in comparison with the traditional extreme learning machines. By a simulation study and a real data analysis we present how the spatial extreme learning machine can be used to improve imputation of missing data and uncertainty prediction estimation.

Stenting for peripheral artery disease of the lower extremities: an evidence-based analysis.

Science.gov (United States)

2010-01-01

In January 2010, the Medical Advisory Secretariat received an application from University Health Network to provide an evidentiary platform on stenting as a treatment management for peripheral artery disease. The purpose of this health technology assessment is to examine the effectiveness of primary stenting as a treatment management for peripheral artery disease of the lower extremities. CONDITION AND TARGET POPULATION Peripheral artery disease (PAD) is a progressive disease occurring as a result of plaque accumulation (atherosclerosis) in the arterial system that carries blood to the extremities (arms and legs) as well as vital organs. The vessels that are most affected by PAD are the arteries of the lower extremities, the aorta, the visceral arterial branches, the carotid arteries and the arteries of the upper limbs. In the lower extremities, PAD affects three major arterial segments i) aortic-iliac, ii) femoro-popliteal (FP) and iii) infra-popliteal (primarily tibial) arteries. The disease is commonly classified clinically as asymptomatic claudication, rest pain and critical ischemia. Although the prevalence of PAD in Canada is not known, it is estimated that 800,000 Canadians have PAD. The 2007 Trans Atlantic Intersociety Consensus (TASC) II Working Group for the Management of Peripheral Disease estimated that the prevalence of PAD in Europe and North America to be 27 million, of whom 88,000 are hospitalizations involving lower extremities. A higher prevalence of PAD among elderly individuals has been reported to range from 12% to 29%. The National Health and Nutrition Examination Survey (NHANES) estimated that the prevalence of PAD is 14.5% among individuals 70 years of age and over. Modifiable and non-modifiable risk factors associated with PAD include advanced age, male gender, family history, smoking, diabetes, hypertension and hyperlipidemia. PAD is a strong predictor of myocardial infarction (MI), stroke and cardiovascular death. Annually, approximately

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 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.

There is a paucity of information regarding sexual functioning in persons with lower extremity amputations. The purpose of this study was to describe sexual and psychological functioning and health status in persons with lower extremity amputation. Self-report surveys assessed sexual functioning (Derogatis Inventory), depression (Beck Depression Inventory, anxiety (State-Trait Anxiety Inventory), and health status (Health Status Questionnaire) in a convenience sample of 30 men with lower extremity amputations. Mean age of the participants was 57 years (range 32-79). Mean duration since amputation was 23 months (range 3-634 months). Twenty one subjects (70%) had trans-tibial and seven subjects (23%) had trans-femoral amputations. A majority of subjects were experiencing problems in several domains of sexual functioning. Fifty three percent (n = 16) of the subjects were engaged in sexual intercourse or oral sex at least once a month. Twenty seven percent (n = 8) were masturbating at least once a month. Nineteen subjects (63%) reported orgasmic problems and 67% were experiencing erectile difficulties. Despite these problems, interest in sex was high in over 90% of the subjects. There was no evidence of increased prevalence of depression or anxiety in these subjects when compared to other outpatient adult populations. Sexual problems were common in the subjects studied. Despite these problems, interest in sex remained high. Few investigations have been directed toward identifying the psychological and social factors that may contribute to these problems and more research with a larger population is needed in this area.

To compare the diagnostic value of gadolinium-enhanced MR angiography with that of conventional digital subtraction angiography for the evaluation of lower extremity arterial occlusive diseases. In 26 patients with symptomatic lower extremity arterial occlusive disease, both conventional digital subtraction angiography (DSA) and gadolinium-enhanced MR angiography (CE-MRA) were performed during the same week. MR angiography was performed using three-dimensional gradient-echo acquisition before, and two sequential acquisitions after, the administration of gadolinium (0.2 mmol/kg). In 23 patients, two separate, contiguous areas were scanned using additional doses. In three patients, only one field with a suspicious lesion was scanned. Three radiologists independently analyzed the CE-MRA and DSA findings of each vascular segment (20 segments per arterial tree) for the presence of obstructive lesions; the grade assigned was either mild or none (less than 50%), stenotic (50%-99%), or occlusion (100%). From among a total of 462 segments, DSA detected 99 which were significantly narrowed (stenosis, 33; occlusion, 66). Using MR angiography, 102 segments (stenosis 39; occlusion, 63) were identified, and 94 lesions (stenosis, 32; occlusion, 62) were graded correctly. Seven lesions were overestimated and four were underestimated. For the detection of hemodynamically significant stenosis or occlusions using MR angiography, sensitivity, specificity, and diagnostic accuracy were 95%, 98%, and 98% (G=3D0.995, P less than 0.001), respectively. To prove the absence of lesions, we repeated DSA in two patients with arterial spasm due to puncture. Three occluded segments seen on DSA, which revealed intact segments on MR angiography, suggested slow distal flow after reconstitution. For the evaluation of lower extremity arterial occlusive disease, the diagnostic value of gadolinium-enhanced MR angiography is comparable with that of digital subtraction angiography.

Full Text Available OBJECTIVES: Vascular injuries to the upper extremities requiring surgical repair are common after accidents. However, neither postoperative functionality nor hemodynamic status of the extremity are routinely described. We evaluated the postoperative functional and hemodynamic status of patients with vascular traumas in the upper extremities. METHODS: 26 patients who suffered penetrating vascular traumas in the upper extremities from November 2008 to December 2011 were retrospectively evaluated. Data on first approach, surgical technique employed and early postoperative outcomes were recorded. Further data on the post-discharge period, including clinical functional status of the arm, Doppler ultrasonography and brachial-brachial index were also evaluated. RESULTS: Average follow up was 33.5±10.8 months. Right (1.05±0.09 and left (1.04±0.08 brachial indexes were measured during follow up,. Doppler ultrasonography showed arterial occlusion in 4 patients (15%. Near-normal brachial-brachial indexes was observed in all four of these patients with occlusion of one of the upper extremity arteries, even though they exhibited limited arm function for daily work. CONCLUSIONS: Evaluation of the postoperative outcomes of this small series of patients with penetrating vascular traumas in the upper extremity revealed that 15% of them suffered occlusion of one artery of the upper extremity. Artery occlusion did not correlate with brachial-brachial Doppler index, probably due to rich collateral circulation, but occlusion was associated with an extremity that was dysfunctional for the purposes of daily work. The result of the brachial-brachial index does not therefore correlate with functionality.

Multiple sclerosis (MS) is one of the most common neurological disorders in young adults. It is characterised by a chronic progressive course with far reaching implications on the patient's private and professional life. Based on the current literature, employment status is analysed in relation to disease-specific, therapeutic, psychosocial, and socioeconomic factors. A special emphasis is placed on the vocational status of MS patients in Germany. According national and international studies, around 40 % of all MS patients are currently unemployed. Main reasons for early retirement are disease-specific factors such as impaired mobility, disability in the upper extremities, fatigue, and cognitive impairment. According to the German Multiple Sclerosis Registry (GMSR), these symptoms are still insufficiently treated. In patients with minor motoric impairment (EDSS ≤ 3.0), depressive symptoms seem to have a major impact on employment status. Disease progression, older age at diagnosis, and hard physical work are negative predictors in terms of employment situation. The lack of flexible working hours, the inability to have flexible resting times at work, a lack of understanding from colleagues and employers as well as the personal attitude were main non-disease-specific reasons for early retirement. The current knowledge on the vocational status in MS is mainly based on international studies (e. g., Scandinavia, England, USA, Australia, MSIF Survey). For Germany, only the GMSR supports significant information on the employment status of MS patients. According to the GMSR, ataxia, fatigue and cognitive dysfunction are still insufficiently treated - a situation that is at least partly due to insufficient treatment options. Comprehensive studies that focus on a broad range of possible influencing factors on vocational status of German MS patients are currently lacking. © Georg Thieme Verlag KG Stuttgart · New York.

To determine whether there is difference between risk factors in patients diagnosed to have clinically documented lower extremity venous disease after confirming the diagnosis radiologically by ultrasonographic and venographic evaluation. This study was performed from January 2002 to January 2005 in Bursa, the fourth biggest city of Turkey situated in the west of country in the Marmara region. The study center is a private imaging center working in conjunction with the Department of Health, which performs diagnostic and therapeutic vascular protocols in the region. Five hundred and fifty-three cases with clinically and radiologically documented diagnoses were evaluated with Multi-Variate Statistical Package 3.13 for the presence of pre-defined clusters of 14 different variables. Other statistical analyses were performed by the Statistical Package for Social sciences, version 13.0. Three different clusters were defined. The variables used to define the clusters were: age, gender, educational level, presence of smoking, amount of smoking (pack/per year), disease symptoms, presence of heart disease and radiologically documented diagnosis. Chronic venous insufficiency and varicose veins are venous system diseases that are most commonly present in association with more than one concomitant risk factors. (author)

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.
Orphan drugs for rare diseases: is it time to revisit their special market access status?

Orphan drugs are intended for diseases with a very low prevalence, and many countries have implemented legislation to support market access of orphan drugs. We argue that it is time to revisit the special market access status of orphan drugs. Indeed, evidence suggests that there is no societal preference for treating rare diseases. Although society appears to assign a greater value to severity of disease, this criterion is equally relevant to many common diseases. Furthermore, the criterion of equity in access to treatment, which underpins orphan drug legislation, puts more value on health improvement in rare diseases than in common diseases and implies that population health is not maximized. Finally, incentives for the development, pricing and reimbursement of orphan drugs have created market failures, including monopolistic prices and the artificial creation of rare diseases. We argue that, instead of awarding special market access status to orphan drugs, there is scope to optimize research and development (R&D) of orphan drugs and to control prices of orphan drugs by means of, for example, patent auctions, advance purchase commitments, pay-as-you-go schemes and dose-modification studies. Governments should consider carefully the right incentive strategy for R&D of orphan drugs in rare diseases.

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.

Full Text Available 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.

Javier Gervas-Arruga

Full Text Available Gaucher disease, the most common lysosomal storage disorder, is caused by β-glucocerebrosidase deficiency. Bone complications are the major cause of morbidity in patients with type 1 Gaucher disease (GD1. Genetic components strongly influence bone remodelling. In addition, chronic inflammation produced by Gaucher cells induces the production of several cytokines, which leads to direct changes in the bone remodelling process and can also affect the process indirectly through other immune cells. In this study, we analysed the association between bone mineral density (BMD, bone marrow burden score, and relevant genetic polymorphisms related to bone metabolism, as well as profiles of proinflammatory cytokines in a GD1 cohort. This study included 83 patients distributed according to bone status. BMD was measured with DXA and broadband ultrasound attenuation; bone marrow involvement was evaluated using MRI. We also analysed 26 SNPs located in 14 genes related to bone metabolism. To assess proinflammatory status, we analysed IL-4, IL-6, IL-7, IL-10, IL-13, MIP-1α, MIP-1β, and TNFα in plasma samples from 71 control participants and GD1 patients. SNP genotype proportions and BMD differed significantly between ESRI c.453-397T>C and VDR c.1024+283G>A variants. We also observed significant associations between GD1 genotypes and bone affectation. When patients were stratified by spleen status, we observed significant correlations between non-/splenectomized groups and Spanish MRI (S-MRI score. Across genotype proportions of non-/splenectomized patients and S-MRI, we observed significant differences in ESRI c.453-397T>C, VDR c.-83-25988G>A, and TNFRSF11B c.9C>G polymorphisms. We observed different significant proinflammatory profiles between control participants, treatment-naïve patients, and patients on enzyme replacement therapy (ERT; between non-/splenectomized patients (between untreated and ERT-treated patients and among those with differing GBA

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.

Coronary heart disease (CHD) is a disease that causes narrowing of the coronary arteries. Currently, there is a hypothesis regarding periodontal infection that increases risk for heart disease. Alkaline phosphatase (ALP) as a marker of inflammation will increase in atherosclerosis and periodontal disease. The objective of this research is analyzing the relationship between the levels of alkaline phosphatase in saliva with periodontal status in patients with CHD and non CHD. Here, saliva of 104 subjects were taken, each 1 ml, and levels of Alkaline Phosphatase was analyzed using Abbott ci4100 architect. We found that no significant difference of Alkaline Phosphatase levels in saliva between CHD patients and non CHD. Therefore, it can be concluded that Alkaline Phosphatase levels in patients with CHD saliva was higher than non CHD and no association between ALP levels with periodontal status.

BACKGROUND—A high prevalence of osteoporosis is reported in Crohn's disease. The pathogenesis is not completely understood but is probably multifactorial. Longstanding Crohn's disease is associated with a deficiency of fat soluble vitamins, among them vitamin K. Vitamin K is a cofactor in the carboxylation of osteocalcin, a protein essential for calcium binding to bone. A high level of circulating uncarboxylated osteocalcin is a sensitive marker of vitamin K deficiency. AIMS—To determine serum and bone vitamin K status in patients with Crohn's disease and to elucidate its relationship with bone mineral density. METHODS—Bone mineral density was measured in 32 patients with longstanding Crohn's disease and small bowel involvement, currently in remission, and receiving less than 5 mg of prednisolone daily. Serum levels of vitamins D and K, triglycerides, and total immunoreactive osteocalcin, as well as uncarboxylated osteocalcin ("free" osteocalcin) were determined. The hydroxyapatite binding capacity of osteocalcin was calculated. Data were compared with an age and sex matched control population. RESULTS—Serum vitamin K levels of CD patients were significantly decreased compared with normal controls (p<0.01). "Free" osteocalcin was higher and hydroxyapatite binding capacity of circulating osteocalcin was lower than in matched controls (p<0.05 and p<0.001, respectively), indicating a low bone vitamin K status in Crohn's disease. In patients, an inverse correlation was found between "free" osteocalcin and lumbar spine bone mineral density (r=−0.375, p<0.05) and between "free" osteocalcin and the z score of the lumbar spine (r=−0.381, p<0.05). Multiple linear regression analysis showed that "free" osteocalcin was an independent risk factor for low bone mineral density of the lumbar spine whereas serum vitamin D was not. CONCLUSIONS—The finding that a poor vitamin K status is associated with low bone mineral density in longstanding Crohn

As a noninvasive and easily available biological fluid, the urine is becoming an important source for disease biomarker study. Change is essential for the usefulness of a biomarker. Without homeostasis mechanisms, urine can accommodate more changes, especially in the early stages of diseases. In this review, we summarize current status and discuss perspectives on the discovery of urine biomarkers in the early stages of diseases. We emphasize the advantages of urine biomarkers compared to plasma biomarkers for the diagnosis of diseases at early stages, propose a urine biomarker research roadmap, and highlight a novel membrane storage technique that enables large-scale urine sample collection and storage efficiently and economically. It is anticipated that urine biomarker studies will greatly promote early diagnosis, prevention, treatment, and prognosis of a variety of diseases, and provide strong support for translational and precision medicine.

Fifty one lower extremities of 26 normal healthy volunteers and 26 extremities of 13 patients with oedema have been studied. Dynamic quantitative lymphoscintigraphy using 99Tc-m antimony sulphide colloid during passive exercise as well as before and after active exercise was performed. parameters of lymphatic function including percentage of radioactivity cleared from the injection site, the percentage uptake by the inguinal lymph nodes, the time of arrival of activity at the regional lymph nodes and the lymphatic reserve index have been evaluated. The percentage clearance of activity from the injection site was found technically difficult to standardize and proved to be an unreliable parameter of lymphatic function. However, the quantitation of nodal uptake, the lymphatic transit time and the lymphatic reserve capacity accurately depicted the lymphatic functional status of an individual. The physiologic parameters of lymphatic function of the contralateral lower extremities were compared and a physiologic difference in the lymphatic capacity of the two limbs was scintigraphically documented.

Mercer, T H; Koufaki, P; Naish, P F

2004-05-01

A significant percentage of patients with end-stage renal disease are malnourished and/or muscle wasted. Uremia is associated with decreased protein synthesis and increased protein degradation. Fortunately, nutritional status has been shown to be a modifiable risk factor in the dialysis population. It has long been proposed that exercise could positively alter the protein synthesis-degradation balance. Resistance training had been considered as the only form of exercise likely to induce anabolism in renal failure patients. However, a small, but growing, body of evidence indicates that for some dialysis patients, favourable improvements in muscle atrophy and fibre hypertrophy can be achieved via predominantly aerobic exercise training. Moreover, some studies tentatively suggest that nutritional status, as measured by SGA, can also be modestly improved by modes and patterns of exercise training that have been shown to also increase muscle fibre cross-sectional area and improve functional capacity. Functional capacity tests can augment the information content of basic nutritional status assessments of dialysis patients and as such are recommended for routine inclusion as a feature of all nutritional status assessments.
Adjusting a cancer mortality-prediction model for disease status-related eligibility criteria

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.

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.

There are little data on patient factors that impact diagnosis rates of celiac disease. This study aims to evaluate the association between patient socioeconomic status and the symptoms at diagnosis of celiac disease. A total of 872 patients with biopsy-proven celiac disease were categorized based on the presence or absence of (1) diarrhea and (2) any gastrointestinal symptoms at diagnosis. Univariate and multivariate analyses were used to assess the association between socioeconomic status and symptoms. Patients without diarrhea at presentation had a higher mean per capita income (US$34,469 versus US$32,237, p = 0.02), and patients without any gastrointestinal symptoms had a higher mean per capita income (US$36,738 versus US$31,758, p symptoms. On multivariable analysis adjusting for sex, age, autoimmune or psychiatric comorbidities, and income, per capita income remained a significant predictor of diagnosis without gastrointestinal symptoms (odds ratio: 1.71, 95% confidence interval: 1.17-2.50, p symptoms of celiac disease are less likely to be diagnosed if they are of lower socioeconomic status. Celiac disease may be under-recognized in this population due to socioeconomic factors that possibly include lower rates of health-seeking behavior and access to healthcare.

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.

[Purpose] This study was conducted to examine the association between Modic classification and the eating habits in patients with degenerative disc disease (DDD) and to determine the influence of nutrition on disease severity. [Subjects and Methods] Sixty patients with DDD visiting a low back pain outpatient clinic were enrolled. Through face-to-face interviews, they completed questionnaires regarding their demographics, disease activity, smoking and alcohol use, concomitant diseases, disease duration, and nutritional status.Exclusion criteria were age 65 years, other comorbidities, missing MRI data, and inability to speak Turkish. [Results] Forty patients were finally included in the study. The frequency with which they consumed water, salt, fast food, eggs, milk, yogurt, cheese, whole wheat bread, white bread, butter, and margarine was recorded. A weak negative correlation was observed between the Modic types and fish and egg consumption. [Conclusion] Modic changes, which indicate the severity of DDD, seem to be correlated to patients' dietary habits. However, studies with comparison groups and larger samples are needed to confirm our promising results before any cause-and-effect relationship can be proposed.

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.

Full Text Available OBJECTIVE: The clinical implication of the coronary artery calcium score (CS is well demonstrated. However, little is known about the association between lower extremity arterial calcification and clinical outcomes. METHODS AND RESULTS: Eighty-two patients with symptomatic peripheral artery disease (age 61.0±12.4 years were followed for 21±11 months. CSs, ranging from the common iliac artery bifurcation to the ankle area, were analyzed through noncontrast multidetector computed tomography images retrospectively. The primary endpoints of this study were amputation and mortality. Old age, diabetes, hyperlipidemia, and end-stage renal disease were associated with higher CSs. Patients with more advanced Fontaine stages also tended to have significantly higher CSs (p = 0.03. During the follow-up period (21±11 months, 29 (35% patients underwent amputation, and 24 (29% patients died. Among the patients who underwent amputation, there were no significant differences in CSs between the amputated legs and the non-amputated legs. In the Cox proportional hazard model with CS divided into quartiles, patients with CS in the highest quartile had a 2.88-fold (95% confidence interval [CI] 1.18-12.72, p = 0.03 and a 5.16-fold (95% CI 1.13-21.61, p = 0.04 higher risk for amputation and all-cause mortality, respectively, than those with CS in the lowest quartile. These predictive effects remained after conventional risk factor adjustment. CONCLUSION: Lower extremity arterial CSs are associated with disease severity and outcomes, including amputation and all-cause mortality, in patients with symptomatic peripheral artery disease. However, the independent predictive value needs further investigation in large scale, prospective studies.

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. Group G3 had, in comparison with the control and cardiovascular patients, significantly lower levels of cholesterol and triglycerides in plasma, as well as lower index of atherosclerosis

Persistent infection with oncogenic Human Papillomavirus (HPV) is associated with the development of cervical cancer with each genotype differing in their relative contribution to the prevalence of cervical disease. HPV DNA testing offers improved sensitivity over cytology testing alone but is accompanied by a generally low specificity. Potential molecular markers of cervical disease include type-specific viral load (VL), integration of HPV DNA into the host genome and methylation of the HPV genome. The aim of this study was to evaluate the relationship between HPV type-specific viral load, integration and methylation status and cervical disease stage in samples harboring HPV16, HPV18, HPV31 or HPV45. Samples singly infected with HPV16 (n = 226), HPV18 (n = 32), HPV31 (n = 75) or HPV45 (n = 29) were selected from a cohort of 4,719 women attending cervical screening in England. Viral load and integration status were determined by real-time PCR while 3’L1-URR methylation status was determined by pyrosequencing or sequencing of multiple clones derived from each sample. Viral load could differentiate between normal and abnormal cytology with a sensitivity of 75% and a specificity of 80% (odds ratio [OR] 12.4, 95% CI 6.2–26.1; p < 0.001) with some variation between genotypes. Viral integration was poorly associated with cervical disease. Few samples had fully integrated genomes and these could be found throughout the course of disease. Overall, integration status could distinguish between normal and abnormal cytology with a sensitivity of 72% and a specificity of 50% (OR 2.6, 95% CI 1.0–6.8; p = 0.054). Methylation levels were able to differentiate normal and low grade cytology from high grade cytology with a sensitivity of 64% and a specificity of 82% (OR 8.2, 95% CI 3.8–18.0; p < 0.001). However, methylation varied widely between genotypes with HPV18 and HPV45 exhibiting a broader degree and higher magnitude of methylated CpG sites than HPV16 and HPV31. This

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.

Many microorganisms that grow at elevated temperatures are able to utilize a variety of carbohydrates pertinent to the conversion of lignocellulosic biomass to bioenergy. The range of substrates utilized depends on growth temperature optimum and biotope. Hyperthermophilic marine archaea (T(opt)>or=80 degrees C) utilize alpha- and beta-linked glucans, such as starch, barley glucan, laminarin, and chitin, while hyperthermophilic marine bacteria (T(opt)>or=80 degrees C) utilize the same glucans as well as hemicellulose, such as xylans and mannans. However, none of these organisms are able to efficiently utilize crystalline cellulose. Among the thermophiles, this ability is limited to a few terrestrial bacteria with upper temperature limits for growth near 75 degrees C. Deconstruction of crystalline cellulose by these extreme thermophiles is achieved by 'free' primary cellulases, which are distinct from those typically associated with large multi-enzyme complexes known as cellulosomes. These primary cellulases also differ from the endoglucanases (referred to here as 'secondary cellulases') reported from marine hyperthermophiles that show only weak activity toward cellulose. Many extremely thermophilic enzymes implicated in the deconstruction of lignocellulose can be identified in genome sequences, and many more promising biocatalysts probably remain annotated as 'hypothetical proteins'. Characterization of these enzymes will require intensive effort but is likely to generate new opportunities for the use of renewable resources as biofuels.

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) ...

The Heat shield for Extreme Entry Environment Technology (HEEET) Project is a NASA STMD and SMD co-funded effort. The goal is to develop and mission infuse a new ablative Thermal Protection System that can withstand extreme entry. It is targeted to support NASA's high priority missions, as defined in the latest decadal survey, to destinations such as Venus and Saturn in-situ robotic science missions. Entry into these planetary atmospheres results in extreme heating. The entry peak heat-flux and associated pressure are estimated to be between one and two orders of magnitude higher than those experienced by Mars Science Laboratory or Lunar return missions. In the recent New Frontiers community announcement NASA has indicated that it is considering providing an increase to the PI managed mission cost (PIMMC) for investigations utilizing the Heat Shield for Extreme Entry Environment Technology (HEEET) and in addition, NASA is considering limiting the risk assessment to only their accommodation on the spacecraft and the mission environment. The HEEET ablative TPS utilizes 3D weaving technology to manufacture a dual layer material architecture. The 3-D weaving allows for flat panels to be woven. The dual layer consists of a top layer designed to withstand the extreme external environment while the inner or insulating layer by design, is designed to achieve low thermal conductivity, and it keeps the heat from conducting towards the structure underneath. Both arc jet testing combined with material properties have been used to develop thermal response models that allows for comparison of performance with heritage carbon phenolic. A 50% mass efficiency is achieved by the dual layer construct compared to carbon phenolic for a broad range of missions both to Saturn and Venus. The 3-D woven flat preforms are molded to achieve the shape as they are compliant and then resin infusion with curing forms a rigid panels. These panels are then bonded on to the aeroshell structure.

Full text: Introduction: Hyperthyroidism is an autoimmune disease in the pathogenesis of which a key role play the antibodies against the thyroid stimulating hormone receptor (TRAb). The aim of this study is to analyze the immune and hormonal status in patients with Graves' disease, who are on thyreostatic therapy and in remission. Materials and methods: 67 patients were studied - 11 men and 56 women - with Graves' disease, mean age 49.7 years (range - 20-76 ). Of these, 55 were on thyreostatic therapy (two subgroups: 27 - treated up to 24 months , and 28 with relapsed disease ) and 12 were in remission up to a year. Patient's condition is assessed as a complex of clinical, biochemical, including hormonal, immune status and ultrasonography of the thyroid gland. We examined thyroid stimulating hormone, free thyroxine, free triiodothyronine, antityreoperoxidase antibodies (Anti-TPO) and TRAb. The patients on therapy are: in hyperthyroidism - 10/ 14 with subclinical hyperthyroidism - 9/8, euthyroid - 7/6 and with subclinical hypothyroidism - 1/0. Results: The patients with hyperthyroidism ( 43.6% ) in both thyreostatic therapy groups have a significantly higher average values of TRAb. The patients with subclinical hyperthyroidism and relapse showed higher levels of TRAb in comparison with those undergoing therapy to 24 months after diagnosing. The values of TRAb in the euthyroid patients in both groups of treatment were 1,5 IU / l. The Anti-TPO values were increased in 78.2% of the patients on therapy and 55.5% of those in remission. Conclusion: With the decrease of thyroid hormones during treatment of Hyperthyroidism the levels of TRAb and Anti-TPO decrease. The TRAb values are useful for the monitoring the effect of the thyreostatic treatment, determining the therapeutic approach in patients with a sustained reduction of TRAb in the course thyreostatic therapy and particularly for relapse

Pulmonary embolism and venous ischemia are acute complications of deep vein thrombosis (DVT) of the lower extremities. Delayed complications include a spectrum of debilitating symptoms referred to as postthrombotic syndrome (PST). Because the early symptoms and patient signs are nonspecific for DVT, careful history taking and radiological evaluation of the extent and migration of thrombus should be used to establish an objective diagnosis and the need for treatment. Anticoagulation therapy is recognized as the mainstay treatment in acute DVT. However, there are few data to suggest any major beneficial effect of the early clearing of massive DVT and PTS. Endovascular, catheter-directed, thrombolysis techniques, used alone or in combination with mechanical thrombectomy devices, have been proven to be highly effective in clearing acute DVT, which may allow the preservation of venous valve function and the prevention of subsequent venous occlusive disease. Definitive management of the underlying anatomic occlusive abnormalities should also be undertaken

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.

Idiopathic hypertrophic cranial pachymeningitis (IHCP) is an uncommon disease of unknown etiology characterized by thickening of the cerebral dura mater with possible associated inflammation. The most frequently described clinical symptoms include headache, cranial nerve palsy, and cerebellar dysfunction. Epilepsy and/or status epilepticus as main presentation is very uncommon. Two consecutive cases are presented of patients manifesting focal status epilepticus secondary to IHCP, with clinical, laboratory [blood test and cerebrospinal fluid (CSF) analysis], neuroradiologic [magnetic resonance imaging (MRI) at 3 Tesla and digital subtraction angiography (DSA)], and therapeutic data. One patient underwent meningeal biopsy; pathology findings are also included. Corticosteroid therapy resulted in clinical improvement in both cases, and neuroimaging showed decreased abnormal morphology, compared to initial findings. In the diagnostic approach to focal status epilepticus or epilepsy, IHCP must be considered a potential, although extremely infrequent, cause. Anti-inflammatory treatment is an effective addition to antiepileptic drug therapy in patients with IHCP. Copyright © 2016 Elsevier B.V. All rights reserved.

Objective: To quantify endothelial function of lower extremity capillary in patients with peripheral vascular disease associated with diabetes mellitus by using DCE-MRI, and to explore the feasibility of DCE-MRI in predicting vascular restenosis in lower extremity after PTA. Methods: During the period form May 2009 to Jan. 2012, a total of 51 patients (study group) with diabetic lower extremity vascular diseases (77 diseased legs in total) were admitted to the hospital and were treated with PTA. Another 20 volunteers were used as control group. K-trans values were measured in soleus muscle using DCE-MRI. Based on the results after 6 months follow-up, the patients were classified into restenosis group and non-restenosis group. The K -trans values and others clinical data were compared between the two groups. Results: Although clinical symptoms and signs were improved in both groups after the treatment, K-trans value of restenosis group showed no obvious changes after PTA, while K-trans value of non-restenosis group was improved significantly. Before PTA, the difference in K -trans value between the two groups was not statistically significant, while K-trans values of the two groups were significantly lower than that of the control group (P<0.05). Conclusion: K-trans value can reflect the endothelial function in diabetes mellitus patients with peripheral vascular disease, and it can also predict the occurrence of restenosis, providing a useful evidence for clinical. therapy.

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

2012-01-01

Full Text Available Motor learning has been found to occur in the rehabilitation of individuals with Parkinson's disease (PD. Through repetitive structured practice of motor tasks, individuals show improved performance, confirming that motor learning has probably taken place. Although a number of studies have been completed evaluating motor learning in people with PD, the sample sizes were small and the improvements were variable. The purpose of this meta-analysis was to determine the ability of people with PD to learn motor tasks. Studies which measured movement time in upper extremity reaching tasks and met the inclusion criteria were included in the analysis. Results of the meta-analysis indicated that people with PD and neurologically healthy controls both demonstrated motor learning, characterized by a decrease in movement time during upper extremity movements. Movement time improvements were greater in the control group than in individuals with PD. These results support the findings that the practice of upper extremity reaching tasks is beneficial in reducing movement time in persons with PD and has important implications for rehabilitation.

To provide insight into the characteristics of chronic disease self-management by mapping publication status and exploring hotspots. Chronic disease is becoming a major public health issue worldwide, highlighting the importance of self-management in this area. Despite the volume and variety of publications, little is known about how 'chronic disease self-management' has developed, since the first publication 40 years ago. Such is the number of publications in the area, that there is a need for a systematic bibliographic examination to enable clinicians and researchers to navigate this literature. A bibliometric analysis of publications was used. Publication status was achieved using BICOMB software, whereas hotspots were identified with Ucinet software. A search of PubMed was conducted for papers published between 1971-2012. By 2011, the number of publications reached 696, a fourfold increase from the previous 10 years, of which 75% came from the USA and UK. There were 1284 journals, which published chronic disease self-management research, involving various disciplines. The research hotspots highlighted various self-management strategies for the following: diabetes; cardiac vascular and pulmonary chronic disease; pain relief for neoplasms; and obesity. Psychological adjustment was a permeating theme in self-management processes as was using internet-based interventions. Self-management in chronic disease publication has been most evident in developed countries. The bibliographic mapping and identification of publication hotspots provides scholars and practitioners with key target journals, as well as a rigorous overview of the field for use in further research, evidence-based practice and health policy development. © 2014 John Wiley & Sons Ltd.

1981-01-01

Scintiangiography of the foot was performed on 210 limbs with peripheral vascular diseases of the lower extremities in comparison with 12 normal limbs. After an intravenous bolus of 10 to 20 mCi of sup(99m)Tc-human serum albumin, the arrival and distribution of activity in foot during reactive hyperemia were observed and photographed on the monitor scope of the gamma camera and recorded on video tape. The activity curve was obtained for several regions of interest and analysed to obtain the arrival time of activity Ta, the maximum counts time Tmax and the perfusion index. Those results were compared with angiography and the pressure index. The gamma camera image provided approximately the state of the peripheral circulation, and the defect or delay of the image was obtained on 93 per cent of the ischemic extremities. The pattern of the activity curves were classified into three types, I: rapid appearance with high activity peak, II: relatively rapid appearance with low activity peak, III: delayed appearance with the absence of the activity peak. In normal subjects and good run-off patients, the typical pattern of the activity curve was mainly observed being to I type, on the other hand, the pattern was generally being to III type in patients with ulcerated or cyanotic foot. The difference between the arrival time of activity of foot and toe under conditions of reactive hyperemia was longer evidently according to degree of arterial occlusion. The perfusion index was well correlated to the pressure index on foot and toe. In conclusion, scintiangiography of the foot is a simple and harmless procedure to evaluate the hemodynamic state of the lower extremities and is applicable for screening the peripheral vascular diseases and postoperative study.

The aim of this study was to identify the most-feared complications of diabetes mellitus (DM), comparing those with diabetic foot pathology with those without diabetic foot pathology. We determined the frequency of patients ranking major lower-extremity amputation (LEA) as their greatest fear in comparison to blindness, death, diabetic foot infection (DFI), or end-stage renal disease (ESRD) requiring dialysis. We further categorized the study group patients (N = 207) by their pathology such as diabetic foot ulcer (DFU), Charcot neuroarthropathy, foot infection, or acute neuropathic fractures and dislocations. The control group (N = 254) was comprised of patients with diabetes who presented with common non-diabetes-related foot pathology. A total of 461 patients were enrolled in this study and included 254 patients without diabetic foot complications and 207 patients with diabetic foot problems. When comparing patients with and without diabetic disease, no significant differences were observed with regard to their fear of blindness, DFI, or ESRD requiring dialysis. Patients with diabetic foot disease (61 of 207, 31.9%) were 136% more likely (odds ratio [OR] = 2.36; 95% CI = 1.51-3.70; P = .002] to rank major LEA as their greatest fear when compared with diabetic patients without foot disease (42 of 254, 16.5%) and were 49% less likely (OR = 0.51; 95% CI = 0.34-0.79; P = .002) to rank death as their greatest fear compared with patients without diabetic foot disease. Patients with diabetic foot pathology fear major LEA more than death, foot infection, or ESRD. Variables that were associated with ranking LEA as the greatest fear were the presence of a diabetic-related foot complication, duration of DM ≥10 years, insulin use, and the presence of peripheral neuropathy. Level II: Prospective, Case controlled study.

Objective 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. Methods 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. Results 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. Conclusion 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.

Fibromyalgia Impact Questionnaire (FIQ was used for assessment of functional status in FM patients. Nottingham Health Profile (NHP and the Hospital Anxiety and Depression Scale (HADS were, respectively, used for assessment of quality of life and psychological status in groups. Results: There was no significant difference between the groups in HADS-total, HADS-depression and HADS-anxiety scores (p>0.05. However, patients with FM had significantly higher NHP-total and NHP-pain scores compared to patients with AS (p<0.05. Conclusion: There was no significant difference between the two groups in psychological distress. Higher NHP-pain scores in patients with FM might have been caused by lower pain threshold in these patients. The generalizability of our findings is also limited because of the relatively small sample size. J Clin Exp Invest 2016; 7 (1: 41-46

Softball is a popular sport with a high incidence of upper extremity injuries. The Kerlan-Jobe Orthopaedic Clinic (KJOC) questionnaire is a validated performance and functional assessment tool used in overhead athletes. Upper extremity pain patterns and baseline KJOC scores have not been reported for active female youth softball pitchers. The purpose of this study was to establish the prevalence of upper extremity pain and its effect in female youth softball pitchers over a competitive season. We hypothesized that participants who missed time due to injury in the past year would have lower KJOC scores. Cross-sectional study; Level of evidence, 3. Fifty-three female softball pitchers aged 12 to 18 years were recruited from softball clinics in Vancouver, British Columbia, Canada. All participants self-identified as a pitcher on a competitive travel team. Participants were administered the KJOC questionnaire before and during the playing season. Missed time due to injury in the past year, current pain patterns, and KJOC scores were primary outcomes. The mean (±SD) preseason KJOC score was 87.2 ± 10.6. In the preseason, 22.6% of pitchers reported playing with arm trouble, and 32.1% missed time due to injury in the past year. The mean KJOC score for pitchers reporting a previous injury (n = 17) was significantly lower compared with those without an injury (n = 36) (79.5 ± 13.8 vs 90.9 ± 6.2, respectively; P = .02). The posterior shoulder was the most commonly reported pain location. For the cohort completing the questionnaire both before and during the playing season (n = 35), mean KJOC scores did not change significantly over the playing season ( P = .64). Lower preseason KJOC scores were significantly related to the in-season injury risk ( P = .016). Pitchers with a preseason score of less than 90 had a 3.5 (95% CI, 1.1-11.2) times greater risk of reporting an in-season injury. Female youth softball pitchers have a high baseline functional status. However, 1 in 3

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.

The role of atherectomy in the treatment of lower extremity peripheral artery disease

Science.gov (United States)

2012-01-01

Background The incidence of lower extremity peripheral artery disease (LE-PAD) continues to increase and associated morbidity remains high. Despite the significant development of percutaneous revascularization strategies, over the past decade, LE-PAD still represents a unique challenge for interventional cardiologists and vascular surgeons. Method Typical features of atherosclerosis that affects peripheral vascular bed (diffuse nature, poor distal runoff, critical limb ischemia, chronic total occlusion) contribute to the disappointing results of traditional percutaneous transluminal angioplasty (PTA). New technologies have been developed in attempt to improve the safety and effectiveness of percutaneous revascularization. Among these, atherectomy, debulking and removing atherosclerotic plaque, offers the potential advantage of eliminating stretch on arterial walls and reducing rates of restenosis. Conclusions This review summarizes the features and the current applications of new debulking devices. PMID:23173800

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.

To assess employment status, difficulties at work and sick leave in inflammatory bowel disease (IBD) patients and their relation with sociodemographic and clinical factors, quality of life (QoL), and anxiety and depression. IBD patients attending an IBD outpatients' clinic received self-report questionnaires on employment status, IBD-related difficulties at work and sick leave (Trimbos/iMTA questionnaire for Costs associated with Psychiatric Illness), sociodemographic factors, QoL (Inflammatory Bowel Disease Questionnaire and 12-item Short-form Health Survey) and anxiety and depression (Hospital Anxiety and Depression Scale). Disease activity was assessed by their gastroenterologist. Associations between paid employment and sick leave with sociodemographic and clinical factors, QoL and anxiety and depression were assessed by regression analyses. In total, 202 IBD patients of working age, with a mean age of 41 years, participated; 63% had Crohn's disease and 37% had ulcerative colitis, and 57% were women and 19% had active disease. In all, 123 (61%) patients were in paid employment, of whom 31 (25%) were on sick leave, whereas 46 (23%) received a disability pension. Concentration problems (72%), low working pace (78%) and delayed work production (50%) were the most prevalent IBD-related work difficulties. IBD patients without paid employment were older and more often women, with active disease, lower QoL and higher anxiety and depression rates. Sick leave was associated with lower QoL and higher anxiety and depression rates. More than half of IBD patients were in paid employment, whereas almost a quarter was receiving a disability pension. A large majority experienced work difficulties. Having no paid employment was associated with poorer QoL and more anxiety and depression symptomatology.

During the last few years great attention has been paid to the evaluation of the impact of extreme temperatures on human health. This paper examines the effect of extreme winter temperature on mortality in Madrid for people older than 65, using ARIMA and GAM models. Data correspond to 1,815 winter days over the period 1986 1997, during which time a total of 133,000 deaths occurred. The daily maximum temperature (Tmax) was shown to be the best thermal indicator of the impact of climate on mortality. When total mortality was considered, the maximum impact occured 7 8 days after a temperature extreme; for circulatory diseases the lag was between 7 and 14 days. When respiratory causes were considered, two mortality peaks were evident at 4 5 and 11 days. When the impact of winter extreme temperatures was compared with that associated with summer extremes, it was found to occur over a longer term, and appeared to be more indirect.
FOOD CONSUMPTION OF CIRRHOTIC PATIENTS, COMPARISON WITH THE NUTRITIONAL STATUS AND DISEASE STAGING

Directory of Open Access Journals (Sweden)

Flavia Feijó NUNES

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.

Cutaneous silent period (CSP) is an inhibitory spinal protective reflex and its afferents consist of A-delta nerve fibers. We aimed to evaluate patients with fibromyalgia (FM) and healthy controls to determine any differences between the groups in terms of CSP duration and latency, and if present, to determine whether there is any relationship with disease characteristics, psychological disorders and quality of life. Thirty-two patients with FM and 32 healthy volunteers were included in the study. The patient and control groups were compared in terms of CSP latency and duration in both upper and lower extremities. Disease characteristics, psychological disorders and quality of life of patients were assessed using the Fibromyalgia Impact Questionnaire (FIQ) and Short Form-36 (SF-36). Patients with CSP measurements equal to or lower than those of the control group were compared with those with higher values than controls in terms of disease characteristics, psychological status and quality of life. Significantly prolonged CSP latencies in both upper and lower extremities were determined in patients compared to controls. We found that prolongation of CSP latency in the lower extremity is associated with disease severity and functional disability. CSP latencies in both upper and lower extremities in patients with FM are longer than in healthy volunteers. Moreover, prolongation of CSP latency in the lower extremity is associated with disease severity and physical functional disability.

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.

Full Text Available Abstract Background Longitudinal studies analyzing the correlations between disease-specific and generic health status questionnaires at different time points in patients with advanced COPD are lacking. The aim of this study was to determine whether and to what extent a disease-specific health status questionnaire (Saint George’s Respiratory Questionnaire, SGRQ correlates with generic health status questionnaires (EuroQol-5-Dimensions, EQ-5D; Assessment of Quality of Life instrument, AQoL; Medical Outcomes Study 36-Item Short-Form Health Survey, SF-36 at four different time points in patients with advanced COPD; and to determine the correlation between the changes in these questionnaires during one-year follow-up. Methods Demographic and clinical characteristics were assessed in 105 outpatients with advanced COPD at baseline. Disease-specific health status (SGRQ and generic health status (EQ-5D, AQoL, SF-36 were assessed at baseline, four, eight, and 12 months. Correlations were determined between SGRQ and EQ-5D, AQoL, and SF-36 scores and changes in these scores. Agreement in direction of change was assessed. Results Eighty-four patients (80% completed one-year follow-up and were included for analysis. SGRQ total score and EQ-5D index score, AQoL total score and SF-36 Physical Component Summary measure (SF-36 PCS score were moderately to strongly correlated. The correlation of the changes between the SGRQ total score and EQ-5D index score, AQoL total score, SF-36 PCS, and SF-36 Mental Component Summary measure (SF-36 MCS score were weak or absent. The direction of changes in SGRQ total scores agreed slightly with the direction of changes in EQ-5D index score, AQoL total score, and SF-36 PCS score. Conclusions At four, eight and 12 months after baseline, SGRQ total scores and EQ-5D index scores, AQoL total scores and SF-36 PCS scores were moderately to strongly correlated, while SGRQ total scores were weakly correlated with SF-36 MCS scores

Patent and exclusivity status of essential medicines for non-communicable disease.

Directory of Open Access Journals (Sweden)

Tim K Mackey

Full Text Available OBJECTIVE: 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. METHODS: 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. MATERIALS: 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. RESULTS: 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. CONCLUSIONS: 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

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 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.

Inflammatory bowel disease (IBD) can be associated with nutritional problems. The aim of this study was to investigate diet and nutritional status of IBD patients. A total of 78 participants (35 men and 43 women aged 18-74 years) were included in this cross-sectional study. The majority (80 %) of the participant received infliximab treatment. Participants filled out disease related questionnaires and 31 participants also a 3-day food record. Body composition was measured and blood samples analysed in order to estimate nutritional status. The majority (87 %) claimed that diet affects digestive tract symptoms and 72 % had changed diet accordingly. The most common foods restricted were dairy products (60 %), processed meat (55 %), soft drinks (46 %), alcohol (45 %) and fast food (44 %). Body mass index was mostly in the overweight range but 46 % of the participants had been diagnosed with some nutritional deficiency since IBD diagnosis (most common was iron deficiency: 39 %). Patients who restricted meat products had lower ferritin values (48 ± 39 vs. 95 ± 74 μg/L, P = 0.011). Intake of vitamin D and calcium were not adequate (65 % below recommeded intake for both) and 60 % had poor vitamin D status. IBD patients often change their dietary intake in order to affect digestive tract symptoms. Many patients have a history of nutrient deficiency. Restriction of dairy and meat consumption is common and is negatively associated with intake or status of micronutrients like calcium and iron. Dietary advice by a dietitian and use of potentially helpful dietary supplements is indicated.

METHODS: Children aged 5-18 years (N = 1315 in the Prediction of Allergies in Taiwanese CHildren (PATCH study were evaluated using questionnaires, anthropometric measurements, and serum levels of 25-hydroxyvitamin D [25(OHD] and total and specific immunoglobulin E (IgE. RESULTS: The mean concentration of serum 25(OHD was 20.4 ng/mL (SD: 7.1 ng/mL. Vitamin D deficiency (defined as serum 25(OHD0.05. CONCLUSIONS: Low serum 25(OHD levels are remarkably common in this population sample of Asian children, suggesting that millions of children living in Taiwan may have suboptimal levels of vitamin D, which should be a matter of public health concern. Our results provides epidemiological evidence against the association of vitamin D status with various allergic diseases and atopy in Asian children.

Extreme temperatures are one of the leading causes of death and disease in both developed and developing countries, and heat extremes are projected to rise in many regions. To reduce risk, heatwave plans and cold weather plans have been effectively implemented around the world. However, much of the world’s population is not yet protected by such systems, including many data-scarce but also highly vulnerable regions. In this study, we assess at a global level where such systems have the potential to be effective at reducing risk from temperature extremes, characterizing (1) long-term average occurrence of heatwaves and coldwaves, (2) seasonality of these extremes, and (3) short-term predictability of these extreme events three to ten days in advance. Using both the NOAA and ECMWF weather forecast models, we develop global maps indicating a first approximation of the locations that are likely to benefit from the development of seasonal preparedness plans and/or short-term early warning systems for extreme temperature. The extratropics generally show both short-term skill as well as strong seasonality; in the tropics, most locations do also demonstrate one or both. In fact, almost 5 billion people live in regions that have seasonality and predictability of heatwaves and/or coldwaves. Climate adaptation investments in these regions can take advantage of seasonality and predictability to reduce risks to vulnerable populations.

The prognosis in adults with congenital aortic valve disease is usually favourable; nevertheless, a number of medical and social factors might hamper long-term prognosis and quality of life. With a focus on physical exercise level, data from the Swedish National Registry on Congenital Heart Disease (SWEDCON) were analysed and variables associated with health-related quality of life in adults with congenital aortic valve disease were identified. In this registry study, SWEDCON was searched for adult patients with isolated congenital aortic valve disease and valid EuroQol-5Dimensions health questionnaire (EQ-5D) data. This study identified 315 patients. The majority (n = 202, 64%) reported best possible health status (EQ-5D(index) = 1) whereas 113 (35%) reported some impairment (EQ-5D(index) 3 h/week was independently associated with best possible health status (EQ-5D(index) = 1; p = 0.013). Moreover presence of cardiovascular symptoms (p 3 h/week was, as a single variable, associated with best possible health status in adults with congenital aortic valve disease. In contrast, a number of medical and social factors are associated with worse self-reported health status. Among these, symptoms, smoking, and educational level are potential targets for modification and intervention. There is a need for studies investigating the effect of increased level of physical exercise in patients with congenital aortic valve disease. © The European Society of Cardiology 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

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

Prevention of waterborne illness is of great concern all over the world. Waterborne diseases represent significant burden of diseases in the globe. Nearly 4% of diseases are attributable to water, sanitation and hygiene, and approximately 2.2 million people die every year due to diarrheal diseases worldwide. This study was carried out to find association of socio-economic features, hygienic status, age groups and gender with prevalence of water borne diseases in Rawalpindi and Islamabad. A research questionnaire was designed with questions related to demographic data, drinking water data and prevalence of water borne disease. The research questionnaire was interviewed to different respondents above 18 years of age randomly selected from different settings of Rawalpindi and Islamabad belonging to different socio-economic statuses. Data was analysed by employing cross tabulation and chi-square test with help of statistical software. The more frequent age group (47%) was 30 to 45 years. Proportion of diarrhea in females and males of middle age group were calculated as 36.11 % and 11.11 %, respectively. The second more frequent reported disease was jaundice with 15.9% of the target population being males and 16.7% females. Diarrhea was observed to be the major waterborne disease constituting 41 % of the population with poor hygiene practices. The hygienic practices were significantly associated with waterborne diseases (P = <0.001). Waterborne diseases were also, associated with financial status (P=0.02) and literacy rate (p=0.03). The current study concludes that improvement in the hygienic conditions and hygienic practices will playa pivotal role to prevent faeco-oral infections and reduce the waterborne disease burden. In targeted areas due to poor economic conditions, the population failed to achieve better hygienic practices and therefore there is a need to strengthen water filtration system and awareness of hygienic routine practices in these areas.

In rheumatology, sufficient disease control is a central part of the treatment concept. However, modern treatment strategies are associated with a substantial economic burden for health care systems. Ecological studies offer the unique opportunity to analyse differences between groups as well as group level effects. In the present analytical multi-site ecological study, we investigated whether more powerful national economies as measured by the gross domestic product per capita (GDPpc) are associated with better disease control in RA patients as measured by the disease activity score 28 (DAS28). We used aggregated data on RA patients from the recently published COMORA study as well as the World Health Organization database. There was a strong negative correlation between DAS28 and GDPpc (r = -0.815; p = 0.0002). Adjustment for sex, smoking status, disease duration or current employment status did not significantly change this association. There was a strong, negative correlation between DAS28 and age (r = -0.870; p < 0.001) and a strong, positive correlation between GDPpc and age (r = 0.737; p = 0.002). Adjustment for age reduced the regression coefficient (DAS28/GDPpc) to -0.000018 (p = 0.054). There was a negative correlation between DAS28 and current employment status (r = -0.642; p = 0.008) and a positive correlation between GDPpc and employment status (r = 0.722; p = 0.002). In conclusion, there is evidence of an association between disease control and GDPpc. This association is alleviated after adjustment for age. Of note, in countries with higher GDPpc, a higher proportion of RA patients are currently employed. This is true despite the fact that RA patients in countries with higher GDPpc are also older.

Full Text Available Peripheral artery diseases (PAD are most serious diabetic complications responsible for the high risk of amputation of lower extremities. The occurrenceof PAD in diabetic patients is much higher than in subjects with undisturbed carbohydrate metabolism. PAD in diabetic patients is frequentlyan asymptomatic condition affecting distal portions of arterial segments and associated with pronounced mediacalcinosis. Standard diagnostic proceduresfor the screening of arterial lesions must be supplemented by non-invasive visualization and measurement of transcutaneous oxygen tensionin patients at risk of PAD and persisting foot ulcers. Of special importance is early diagnosis of critical limb ischemia and prevention of foot lesions.Combined treatment of diabetic foot syndrome in patients with critical limb ischemia includes normalization of foot circulation, surgical interventionand conservative therapy of the wound, monitoring concomitant micro- and macrovascular diabetic complications?

Full Text Available Luciana Baroni,1 Cristina Zuliani2 1Primary Care Unit, Northern District, Azienda ULSS 9 Treviso, Italy; 2Department of Neurology, General Hospital, Mirano, Venice, Italy Abstract: Nutrition is becoming an important tool in the management of the main chronic diseases, including Parkinson's disease (PD. 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.

Extreme external events is emerged as significant risk contributor to the nuclear power plants after Fukushima Daiichi accident due to the catastrophic earthquake followed by great tsunami greater than a design basis. This accident shows that the extreme external events have the potential to simultaneously affect redundant and diverse safety systems and thereby induce common cause failure or common cause initiators. The probabilistic risk assessment methodology has been used for the risk assessment and safety improvement against the extreme natural hazards. The earthquake and tsunami hazard is an important issue for the nuclear industry in Korea. In this paper, the role and application of probabilistic safety assessment for the post Fukushima action will be introduced. For the evaluation of the extreme natural hazard, probabilistic seismic and tsunami hazard analysis is being performed for the safety enhancement. The research activity on the external event PSA and its interim results will be introduced with the issues to be solved in the future for the reliability enhancement of the risk analysis results.

Long-standing chronic diseases such as rheumatoid arthritis are known to be associated with impairment of nutritional status to some degree. The present study aimed to assess nutritional status of women with rheumatoid arthritis and compare their ingestion of certain micronutrients with dietary reference intakes. In this cross-sectional study, 90 eligible women were recruited. After examination, all patients were evaluated on the basis of disease activity score, calculated using the number of tender and swollen joints, patient global assessment of pain and high sensitivity C-reactive protein (CRP). A three-day 24 h recall was completed and a 10 ml fasting blood sample was obtained to assess the plasma levels of malondialdehyde, total antioxidant and CRP. Despite normal BMI, intake of energy and micronutrients including calcium, folic acid, zinc, magnesium and vitamin B6 were considerably lower compared with the dietary reference intakes. There was no significant relationship between intake of different nutrients or food groups and disease activity score and the biochemical markers including malondialdehyde, CRP and total antioxidant. Intake of energy and some micronutrients were significantly lower than the recommended values. However, no relationship was found between intake of different food groups or nutrients with disease activity or serum antioxidant capacity.

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)

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

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 Abstract Background The objective was to review all available literature concerning Type D (distressed personality among the general population and to discuss its implications for research on health status, disease-promoting mechanisms and work-related problems in non-clinical populations. Methods A computerized search of the literature was performed independently and in duplicate by both investigators on December 21st, 2009. Published research reports were included if they studied Type D personality among the general population. Nineteen articles were selected and they were subjected to an 11-item standardised quality checklist by both investigators. Results The methodological quality of the selected studies was adequate to high. The studies included in this review showed that the presence of Type D characteristics had a negative impact on mental health status (more symptoms of depression, anxiety, post-traumatic stress disorder, mental distress, passive coping, and less social support and physical health status (more somatic complaints, lower health status, more influenza-like illness reporting. Other studies reported on behavioral and biological mechanisms of disease in apparently healthy individuals with a Type D personality. Finally, some studies also showed a negative effect of Type D personality on work-related problems (higher absence-leave, higher levels of vital exhaustion and burnout, and more work-related stress. Conclusions Type D personality is a vulnerability factor for general psychological distress that affects mental and physical health status and is associated with disease-promoting mechanisms and work-related problems in apparently healthy individuals.

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.

Proponents of peritoneal drainage (PD) hypothesize that it allows stabilization before laparotomy. We examined this hypothesis by comparing clinical status before and after either PD or primary laparotomy (LAP). In an ethically approved, international, prospective randomized controlled trial (2002-2006), extremely low birth weight (drainage does not immediately improve clinical status in extremely low birth weight infants with bowel perforation. The use of PD as a stabilizing or temporizing measure is not supported by these results. Copyright 2010 Elsevier Inc. All rights reserved.

Thyroid dermopathy is not a frequent feature of hyperthyroid Graves' disease, being present in less than 5% of the patients. Graves' disease has been shown to exist in euthyroid or hypothyroid forms in untreated patients. Here, we describe a case of hypothyroid Graves' disease with elephantiasis nostras verrucosa (ENV), which is an extreme form of thyroid dermopathy (TD). A 58-year-old female patient was admitted to the emergency department with somnolence, hypothermia, and bradycardia. Her mental status gradually worsened, resulting in a deep coma. She was intubated and followed in the intensive care unit, as she needed mechanical ventilatory assistance due to respiratory failure. She also had bilateral non-pitting edema, a cobblestone-like appearance, and hyperkeratotic greenish-brown-colored lesions in the pretibial and dorsal regions of the feet that were compatible with ENV. Hypothyroid Graves' disease is a very rare condition among autoimmune thyroid disorders, and ENV is an extremely rare form of TD. Here, we present a patient with hypothyroid Graves' disease and ENV.

Coutinho-Abreu, Iliano V.; Zhu, Kun Yan; Ramalho-Ortigao, Marcelo

2009-01-01

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.

Full Text Available Many disease-susceptible SNPs exhibit significant disparity in ancestral and derived allele frequencies across worldwide populations. While previous studies have examined population differentiation of alleles at specific SNPs, global ethnic patterns of ensembles of disease risk alleles across human diseases are unexamined. To examine these patterns, we manually curated ethnic disease association data from 5,065 papers on human genetic studies representing 1,495 diseases, recording the precise risk alleles and their measured population frequencies and estimated effect sizes. We systematically compared the population frequencies of cross-ethnic risk alleles for each disease across 1,397 individuals from 11 HapMap populations, 1,064 individuals from 53 HGDP populations, and 49 individuals with whole-genome sequences from 10 populations. Type 2 diabetes (T2D demonstrated extreme directional differentiation of risk allele frequencies across human populations, compared with null distributions of European-frequency matched control genomic alleles and risk alleles for other diseases. Most T2D risk alleles share a consistent pattern of decreasing frequencies along human migration into East Asia. Furthermore, we show that these patterns contribute to disparities in predicted genetic risk across 1,397 HapMap individuals, T2D genetic risk being consistently higher for individuals in the African populations and lower in the Asian populations, irrespective of the ethnicity considered in the initial discovery of risk alleles. We observed a similar pattern in the distribution of T2D Genetic Risk Scores, which are associated with an increased risk of developing diabetes in the Diabetes Prevention Program cohort, for the same individuals. This disparity may be attributable to the promotion of energy storage and usage appropriate to environments and inconsistent energy intake. Our results indicate that the differential frequencies of T2D risk alleles may

The study investigated the nutrient status of some ponds soils, considering the importance of bottom soils on the productivity and impact of Brackish water semi-intensive shrimp ponds. The study indicated the soils fairly rich in total N, available Ca and Na. p H , EC, organic matter, total N, available Ca, Na, P, S, due to ponds were highly significant statistically (P 1 >h 3 >h 2 . Available P in the fallow ponds was slightly less than the healthy ponds but much higher than the diseases ponds. Quite reverse the sequence (h 2 >h 3 >h 1 ) was found in regard to the variation in available S content of soils within the Health classes. The diseased pond soils generally had available S in amounts almost 100 μg/g more than the healthy ponds. The observation indicated that along with other environmental factor higher Sulfur and Phosphorus content of the soil might be responsible for the outbreak of disease.(author)

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.

Full Text Available Purpose. Motor freezing, the inability to produce effective movement, is associated with decreasing amplitude, hastening of movement, and poor coordination. We investigated how manipulations of movement amplitude and cadence affect upper extremity (UE coordination as measured by the phase coordination index (PCI—only previously measured in gait—and freezing of the upper extremity (FO-UE in people with Parkinson's disease (PD who experience freezing of gait (PD + FOG, do not experience FOG (PD-FOG, and healthy controls. Methods. Twenty-seven participants with PD and 18 healthy older adults made alternating bimanual movements between targets under four conditions: Baseline; Fast; Small; SmallFast. Kinematic data were recorded and analyzed for PCI and FO-UE events. PCI and FO-UE were compared across groups and conditions. Correlations between UE PCI, gait PCI, FO-UE, and Freezing of Gait Questionnaire (FOG-Q were determined. Results. PD + FOG had poorer coordination than healthy old during SmallFast. UE coordination correlated with number of FO-UE episodes in two conditions and FOG-Q score in one. No differences existed between PD−/+FOG in coordination or number of FO-UE episodes. Conclusions. Dyscoordination and FO-UE can be elicited by manipulating cadence and amplitude of an alternating bimanual task. It remains unclear whether FO-UE and FOG share common mechanisms.

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.

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 determine which factors are associated with higher costs of urethroplasty procedure and whether these factors have been increasing over time. Identification of determinants of extreme costs may help reduce cost while maintaining quality. We conducted a retrospective analysis using the 2001-2010 Healthcare Cost and Utilization Project-Nationwide Inpatient Sample (HCUP-NIS). The HCUP-NIS captures hospital charges which we converted to cost using the HCUP cost-to-charge ratio. Log cost linear regression with sensitivity analysis was used to determine variables associated with increased costs. Extreme cost was defined as the top 20th percentile of expenditure, analyzed with logistic regression, and expressed as odds ratios (OR). A total of 2298 urethroplasties were recorded in NIS over the study period. The median (interquartile range) calculated cost was $7321 ($5677-$10,000). Patients with multiple comorbid conditions were associated with extreme costs [OR 1.56, 95% confidence interval (CI) 1.19-2.04, P = .02] compared with patients with no comorbid disease. Inpatient complications raised the odds of extreme costs (OR 3.2, CI 2.14-4.75, P costs (OR 1.78, 95% CI 1.2-2.64, P = .005). Variations in patient age, race, hospital region, bed size, teaching status, payor type, and volume of urethroplasty cases were not associated with extremes of cost. Cost variation for perioperative inpatient urethroplasty procedures is dependent on preoperative patient comorbidities, postoperative complications, and surgical complexity related to graft usage. Procedural cost and cost variation are critical for understanding which aspects of care have the greatest impact on cost. Copyright © 2016 Elsevier Inc. All rights reserved.

Purpose: To date, few studies have evaluated the impact of preoperative radiotherapy (pRT) on long-term health status of rectal cancer survivors. Using a population-based sample, we assessed the impact of pRT on general and disease-specific health status of rectal cancer survivors up to 10 years postdiagnosis. The health status of older (≥75 years old at diagnosis) pRT survivors was also compared with that of younger survivors. Methods and Materials: Survivors identified from the Eindhoven Cancer Registry treated with surgery only (SU) or with pRT between 1998 and 2007 were included. Survivors completed the Short Form-36 (SF-36) health survey questionnaire and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Colorectal 38 (EORTC QLQ-CR38) questionnaire. The SF-36 and EORTC QLQ-CR38 (sexuality subscale) scores of the survivors were compared to an age- and sex-matched Dutch normal population. Results: A total of 340 survivors (response, 85%; pRT survivors, 71%) were analyzed. Overall, survivors had similar general health status. Both short-term (<5 years) and long-term (≥5 years) pRT survivors had significantly poorer body image and more problems with gastrointestinal function, male sexual dysfunction, and defecation than SU survivors. Survivors had comparable general health status but greater sexual dysfunction than the normal population. Older pRT survivors had general and disease-specific health status comparable to that of younger pRT survivors. Conclusions: For better survivorship care, rectal cancer survivors could benefit from increased clinical and psychological focus on the possible long-term morbidity of treatment and its effects on health status.

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.

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.

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.

Coronary heart disease (CHD) is an abnormal narrowing of heart arteries associated with local accumulation of lipids, in the form of cholesterol and triglycerides. Periodontal disease is a chronic inflammatory that suggests link to the development of CHD. In periodontitis have been reported changes in lipid profile, include increased of cholesterol levels of blood. Objective: to analyse correlation between blood cholesterol level with periodontal status of CHD and non CHD subjects. Methods: Periodontal status and blood cholesterol level of 60 CHD and 40 non CHD subjects was measured. Result: Blood cholesterol level in CHD subjects differs from non CHD subjects (p=0.032). Blood cholesterol level correlates with pocket depth (p=0.003) and clinical attachment loss (CAL) (p=0.000) in CHD subjects. Blood cholesterol level correlates with pocket depth (p=0.010) in non CHD subjects. There is no significant correlation between blood cholesterol level and bleeding on probing (BOP) in CHD subjects. There is no significant correlation between blood cholesterol level with BOP and CAL in non CHD subjects. Conclusion: Blood cholesterol level in control group is higher than CHD patients. Blood cholesterol level positively associated with pocket depth (r=0.375) and CAL (r=0.450) in CHD patients. Blood cholesterol level is positively associated with pocket depth (r=0.404) in control group.

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.

To investigate the effects of venous diseases at different anatomical localizations on the qualities of life of patients with varicose veins. The study included 354 cases, which was referred to a private vascular and interventional radiology center in Bursa, Turkey between January 2005 to January 2006. The cases were diagnosed with visual inspection and were clinically indicative of varicose veins. Color Doppler ultrasonography was used to radiologically examine the varicose veins. All cases were accepted as class II criteria according to the Clinical, Etiologic, Anatomic, Pathophysiologic classification. The generic Short Form Health Survey-36 (SF-36) was used to measure physical and mental quality of life (QOL). High scores indicated good QOL. The Statistical Package for Social Sciences version 13.0 program was used for the statistical evaluation. When the life SF-36 quality parameters of cases with different anatomical localizations of the varicose veins were examined, only the mental health scores were found to differ in different groups (pemotional role scores among the mental state determinants. When females and males with deep vein disease were compared, significant differences were found among both physical and mental health determinants. Anatomical localization of lower extremity varicose veins can be accepted as a predictive factor in determining the life qualities of patients with varicosities in their lower limb, and should be used to regulate their therapy and follow up protocols.

Full Text Available Background: Upper extremity injured workers are an under-studied population. A descriptive comparison of workers with shoulder, elbow and hand injuries reporting to a Canadian Workplace Safety and Insurance Board (WSIB clinic was undertaken. Objective: To determine if differences existed between injury groups stratified by current work status. Methods: All WSIB claimants reporting to our upper extremity clinic between 2003 and 2008 were approached to participate in this descriptive study. 314 working and 146 non-working WSIB claimants completed the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH; Short Form health survey (SF36; Worker’s Limitations Questionnaire and the Work Instability Scale. Various parametric and non-parametric analyses were used to assess significant differences between groups on demographic, work and health related variables. Results: Hand, followed by the shoulder and elbow were the most common site of injury. Most non-workers listed their current injury as the reason for being off work, and attempted to return to work once since their injury occurrence. Non-workers and a subset of workers at high risk for work loss showed significantly worse mental functioning. Workers identified physical demands as the most frequent injury-related on the job limitation. 60% of current workers were listed as low risk for work loss on the Work Instability Scale. Conclusions: Poorer mental functioning, being female and sustaining a shoulder injury were risk factors for work instability. Our cohort of injured non-workers were unable to return to work due to their current injury, reinforcing the need to advocate for modified duties, shorter hours and a work environment where stress and injury recurrence is reduced. Future studies examining pre-injury depression as a risk factor for prolonged work absences are warranted.

To investigate the independent effects of antihypertensive treatment and blood pressure (BP) levels on physical and mental health status in patients with arterial disease. Cross-sectional analyses were conducted within the single-centre Secondary Manifestations of ARTerial disease (SMART) study, in a hospital care setting. A total of 5877 patients (mean age 57 years) with symptomatic and asymptomatic arterial disease underwent standardized vascular screening. The primary outcome was self-rated physical and mental health assessed using the 36-item short-form health survey. In the total population, antihypertensive drug use and increased intensity of antihypertensive treatment were associated with poorer health status independent of important confounders including BP levels; adjusted mean differences [95% confidence interval (CI)] in physical and mental health between n = 0 and n ≥ 3 antihypertensives were -1.2 (-2.1; -0.3) and -3.5 (-4.4; -2.6), respectively. Furthermore, both lower systolic and lower diastolic BP levels were related to poorer physical and mental health status independent of antihypertensive treatment. Mean differences (95% CI) in physical and mental health status per SD decrease in systolic BP were -0.56 (-0.84; -0.27) and -0.32 (-0.61; -0.03) and per SD decrease in diastolic BP were -0.50 (-0.78; -0.23) and -0.08 (-0.36; 0.20), respectively. The association between low BP and poor health status was particularly present in patients with coronary artery disease. In a population of patients with asymptomatic and symptomatic arterial disease, antihypertensive treatment and lower BP levels are independently associated with poorer self-rated physical and mental health. These findings suggest that different underlying mechanisms may explain these independent associations. © 2013 The Association for the Publication of the Journal of Internal Medicine.

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.

Leiomyosarcoma (LMS) can originate from the retroperitoneum, uterus, extremity, and trunk. It is unclear whether tumors of different origin represent discrete entities. We compared clinicopathologic features and outcomes following surgical resection of LMS stratified by site of origin. Patients with LMS undergoing resection at a single institution were retrospectively reviewed. Clinicopathologic variables were compared across sites. Survival was calculated using the Kaplan-Meier method and compared using log-rank and Cox regression analyses. From 1983 to 2011, 138 patients underwent surgical resection for LMS. Retroperitoneal and uterine LMS were larger, higher grade, and more commonly associated with synchronous metastases. However, disease-specific survival, recurrence-free survival, and recurrence patterns were not significantly different across the four sites. Synchronous metastases (HR 3.20, P < 0.001), but not site of origin, size, grade, or margin status, were independently associated with worse DSS. A significant number of recurrences and disease-related deaths were noted beyond 5 years. Although larger and higher grade, retroperitoneal and uterine LMS share similar survival and recurrence patterns with their trunk and extremity counterparts. LMS of various anatomic sites may not represent distinct disease processes based on clinical outcomes. The presence of metastatic disease remains the most important prognostic factor for LMS. © 2015 Wiley Periodicals, Inc.

The authors present the case of a 6-year-old boy with a good neurological outcome from extreme hyponatraemia caused by autoimmune hypoadrenalism. He presented with 1 week of reduced appetite, lethargy, vomiting and one episode of diarrhoea. He was described as being slightly unsteady on his feet. Clinically he was alert, although intermittently confused, with dry mucous membranes and sunken eyes. Serum sodium was 96 mmol/l with normal serum potassium and renal function. He was initially treated with 3% saline intravenously, and his serum sodium increased to 128 mmol/l by day 3. He developed slurred speech and ataxia on day 4, although MRI brain showed no evidence of pontine myelinosis, and the symptoms resolved over 1 week. A Synacthen test on day 10 confirmed a diagnosis of Addison’s disease and he was commenced on hydrocortisone and fludrocortisone replacement therapy. At 5 months follow-up there are no obvious neurological or developmental sequelae. PMID:22679234

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

The heterogeneity of medical complications that lead to amputation has resulted in a diverse patient population with differing rehabilitation needs; however, the rehabilitation trends for patients with lower extremity amputations across Canada have not been studied previously. To describe trends in rehabilitation after lower extremity amputations and the factors affecting rehabilitation length of stay in Canada. Retrospective cohort analysis. Canadian inpatient rehabilitation facilities that received persons with lower extremity amputations discharged from academic or community hospitals. Patients underwent lower extremity amputations between 2006 and 2009 for nontraumatic indications and were then discharged to a rehabilitation facility. Patients were identified from the Canadian Institute for Health Information's Discharge Abstract Database that includes hospital admissions across Canada except Quebec. Inpatient rehabilitation after lower extremity amputations. Length of stay, discharge destination, and change in total and motor function scores. The analysis included 5342 persons who underwent lower extremity amputations, 1904 of whom were transferred to a rehabilitation facility (36%). Patients most commonly underwent single below-knee (74%) and above-knee (17%) amputations. The duration of rehabilitation varied by whether the amputation was performed by a vascular (median = 36 days), orthopedic (median = 38 days), or general surgeon (median = 35 days). The overall median length of stay was 36 days. Most patients (72%) subsequently were discharged home and 9% were readmitted to hospital. Predictors of longer rehabilitation included amputation by an orthopedic surgeon (beta = 5.0, P ≤ .01), older age (beta = 0.2, P ≤ .01), and a history of ischemic heart disease (beta = 3.8, P = .03) or congestive heart failure (beta = 5, P = .04). Patients who spent Canada after lower extremity amputation varies by the type of surgeon performing the amputation. Advanced age

Water is scarce and, in general, a low quality resource in desert areas and the Indian desert is no exception. With this in view, the present study was taken up to survey the status of common water-borne diseases epidemiological trends in the desert city Bikaner (NW Rajasthan). In the city, 15.5 per cent population and 44.5 per cent families were found to suffer from one or more common water-borne diseases including amoebiasis, diarrhoea, dysentery, jaundice and typhoid. No case of fluorosis was recorded. The highest incidence was that of diarrhoea (5.4 per cent population). The worst affected and safe zones in the city were identified and the trends of different diseases in different zones of the city are discussed. The highest incidence of diseases was noted during summer (58.8 per cent) followed by winter (34.1 per cent) and monsoon (7.0 per cent). Relationship of diseases with population attributes like age, education, economy and family size are also discussed. Attributes for contamination of drinking water have been tried to identify and safety measures suggested.

Full Text Available In South Asia, Haemaphysalis spinigera tick transmits Kyasanur Forest Disease Virus (KFDV, a flavivirus that causes severe hemorrhagic fever with neurological manifestations such as mental disturbances, severe headache, tremors, and vision deficits in infected human beings with a fatality rate of 3–10%. The disease was first reported in March 1957 from Kyasanur forest of Karnataka (India from sick and dying monkeys. Since then, between 400 and 500 humans cases per year have been recorded; monkeys and small mammals are common hosts of this virus. KFDV can cause epizootics with high fatality in primates and is a level-4 virus according to the international biosafety rules. The density of tick vectors in a given year correlates with the incidence of human disease. The virus is a positive strand RNA virus and its genome was discovered to code for one polyprotein that is cleaved post-translationally into 3 structural proteins (Capsid protein, Envelope Glycoprotein M and Envelope Glycoprotein E and 7 non-structural proteins (NS1, NS2A, NS2B, NS3, NS4A, NS4B, and NS5. KFDV has a high degree of sequence homology with most members of the TBEV serocomplex. Alkhurma virus is a KFDV variant sharing a sequence similarity of 97%. KFDV is classified as a NIAID Category C priority pathogen due to its extreme pathogenicity and lack of US FDA approved vaccines and therapeutics; also, the infectious dose is currently unknown for KFD. In India, formalin-inactivated KFDV vaccine produced in chick embryo fibroblast is being used. Nevertheless, further efforts are required to enhance its long-term efficacy. KFDV remains an understudied virus and there remains a lack of insight into its pathogenesis; moreover, specific treatment to the disease is not available to date. Environmental and climatic factors involved in disseminating Kyasanur Forest Disease are required to be fully explored. There should be a mapping of endemic areas and cross-border veterinary

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 education (education (>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.

Objective: In a time when diagnostic methods and above all, surgical as well as interventional radiological treatment for aortic aneurysms and aortic dissections have reached a point nobody could think of a few years back, the present authors feel that it is worth while to remind oneself of the natural course of disease in these conditions. Taking into consideration the high morbidity and mortality rate in surgically treated patients with aortic dissection, and the high complication rate per- and postoperatively, it also seems right to ask if a more expectative and conservative approach to the condition sometimes perhaps may be justified. Methods and material: Two case reports are given. One was a 15-year-old boy with Stanford (Daily) type B dissection who statistically ought to have a good prognosis, but who died within 2 h after onset of symptoms. The other patient, a middle-aged woman with Stanford type A dissection, survived for 25 years without operation. Conclusion: These two cases, though not unique viewed separately, we consider to represent the extremes of the condition and also a natural course of disease, while none of them was operated on

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. Depressed patients with RA tend to be overweight or obese and, therefore, have an unfavorable lipid profile.

Context: Multiple autoimmune disorders (e.g. Addison’s disease, type 1 diabetes, celiac disease) are associated with HLA-DR3, but it is likely that alleles of additional genes in linkage disequilibrium with HLA-DRB1 contribute to disease. Objective: The objective of the study was to characterize major histocompatability complex (MHC) haplotypes conferring extreme risk for autoimmune Addison’s disease (AD). Design, Setting, and Participants: Eighty-six 21-hydroxylase autoantibody-positive, nonautoimmune polyendocrine syndrome type 1, Caucasian individuals collected from 1992 to 2009 with clinical AD from 68 families (12 multiplex and 56 simplex) were genotyped for HLA-DRB1, HLA-DQB1, MICA, HLA-B, and HLA-A as well as high density MHC single-nucleotide polymorphism (SNP) analysis for 34. Main Outcome Measures: AD and genotype were measured. Result: Ninety-seven percent of the multiplex individuals had both HLA-DR3 and HLA-B8 vs. 60% of simplex AD patients (P = 9.72 × 10−4) and 13% of general population controls (P = 3.00 × 10−19). The genotype DR3/DR4 with B8 was present in 85% of AD multiplex patients, 24% of simplex patients, and 1.5% of control individuals (P = 4.92 × 10−191). The DR3-B8 haplotype of AD patients had HLA-A1 less often (47%) than controls (81%, P = 7.00 × 10−5) and type 1 diabetes patients (73%, P = 1.93 × 10−3). Analysis of 1228 SNPs across the MHC for individuals with AD revealed a shorter conserved haplotype (3.8) with the loss of the extended conserved 3.8.1 haplotype approximately halfway between HLA-B and HLA-A. Conclusion: Extreme risk for AD, especially in multiplex families, is associated with haplotypic DR3 variants, in particular a portion (3.8) but not all of the conserved 3.8.1 haplotype.

The aim of the study was to analyse the impact of chronic disease on the quality of life (QoL) and how QoL changes with comorbidity and socioeconomic status in persons who attend primary health care centres. The group of participants comprised 2,560 people who contacted six primary health care centres in Ankara. The level of QoL was determined by the World Health Organization Quality of Life Questionnaire Abbreviated Version (WHOQOL-BREF). Mental disorders and diabetes-hypertension comorbidity had the most negative effect on the QoL. In the physical domain of the WHOQOL-BREF, the effect of diabetes-hypertension comorbidity is greater than the additive effect of hypertension and diabetes individually. The co-occurrence of any disease with cardiovascular disease does not change QoL within any domain, except for the co-occurrence of any disease with musculoskeletal diseases which deteriorated QoL in the physical domain. The higher income and socioeconomic status corresponded to higher QoL. The effect of comorbidity on QoL can be different from the additive effects of the co-occurring diseases. Socioeconomic factors undoubtedly affect the relationship between chronic diseases and QoL, and this relationship points to health inequities among socioeconomic groups.

Extreme weather and climate-related events affect human health by causing death, injury, and illness, as well as having large socioeconomic impacts. Climate change has caused changes in extreme event frequency, intensity, and geographic distribution, and will continue to be a driver for change in the future. Some of these events include heat waves, droughts, wildfires, dust storms, flooding rains, coastal flooding, storm surges, and hurricanes. The pathways connecting extreme events to health outcomes and economic losses can be diverse and complex. The difficulty in predicting these relationships comes from the local societal and environmental factors that affect disease burden. More information is needed about the impacts of climate change on public health and economies to effectively plan for and adapt to climate change. This paper describes some of the ways extreme events are changing and provides examples of the potential impacts on human health and infrastructure. It also identifies key research gaps to be addressed to improve the resilience of public health to extreme events in the future.

Full Text Available Purpose: To evaluate the association between the development of extremity fracture and visual impairment in adults. Material and Method: This study included 56 patients (patient group aged 18 years or older who had extremity fractures due to a fall. The control group (n=42 was selected from visitors who had regular medical check-ups at our hospital. Each participant underwent a full ophthalmologic examination. Mean age was compared by Student’s t test. The other variables were compared by chi-square test. Results: The prevalence of subjects with visual impairment was significantly higher in the patients group (78.6% than in the control group (38.1% (p<0.05. The prevalence of treatable eye diseases such as cataract and refractive errors were significantly higher in the patient group than in the control group (p<0.05 for both. Twenty-eight patients (50% in the patient group and 8 subjects in the control group had visual acuities lower than 0.5 (p<0.05. Discussion: We have found that the prevalence of visual impairment was significantly higher in adults with extremity fractures due to falls than in the control group. Hence, we believe that regular ophthalmological examination in adults, providing regular use of eyeglasses in patients with refractive errors, and timely treatment of treatable eye diseases such as cataract could decrease the extremity fractures from falls in adults.

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.

Extreme weather and climate events affect human health by causing death, injury, and illness, as well as having large socio-economic impacts. Climate change has caused changes in extreme event frequency, intensity and geographic distribution, and will continue to be a driver for changes in the future. Some of the extreme events that have already changed are heat waves, droughts, wildfires, flooding rains, coastal flooding, storm surge, and hurricanes. The pathways connecting extreme events to health outcomes and economic losses can be diverse and complex. The difficulty in predicting these relationships comes from the local intricacies of societal and environmental factors that influences the level of exposure. The goal of this presentation is to discuss the national security implications of changes in extreme weather events and demonstrate how changes in extremes can lead to a host cascading issues. To illustrate this point, this presentation will provide examples of the various pathways that extreme events can increase disease burden and cause economic stress.

Objective: To identify variables associated with poor performance status of hepatocellular carcinoma (HCC) patients and to compare impact of stage of liver disease and that of hepatoma on functional status of patient. Patients and Methods: We included 254 confirmed cases of liver cancer in a crosssectional analytical study carried out at Doctors Hospital Lahore. Patient's clinical, biochemical and radiological variables were correlated with Karnofsky's performance status (KPS) using pearson correlation. Model for End stage Liver Disease (MELD) and Cancer of Liver Italian Program (CLIP) were evaluated for predicting performance status using Receiver Operating Characteristic (ROC) curve. Results: Mean age of patients was 56.69 (±10.34) and male to female ratio was 2.47: 1 (181/73). On KPS evaluation 84 (33.1%) patients scored between 80-100, 147 (57.9%) had score of 50-70 while in 23 (9.1%) KPS score was between 0-40. Variables associated with poor performance status were bilirubin> 3mg/dl (p value 0.00), albumin< 2.5 g/dl (p value 0.00), creatinine > 1.2mg/dl (p 0.00), prothrombin time> 16seconds (p value 0.00), size of tumor >7cm (p value 0.02), tumor involving > 50% of liver mass (p value 0.00) and vascular invasion (p value 0.00). Both stage of liver disease as determined by MELD and stage of liver cancer as per CLIP scores had strong correlation (p value 0.00) with poor performance status of patient. Area under ROC curve was 0.764 for MELD score and 0.785 for CLIP score. Conclusion: Performance status of liver cancer patients is affected by both stage of liver disease and that of liver tumor. Patients with MELD score above 16 and CLIP score above 4 have poor performance status. (author)

There are various climate risks that are caused or influenced by climate change. They are known to have a wide range of physical, economic, environmental and social impacts. Apart from damages to the physical environment, many climate risks (climate variability, extreme events and climate-related hazards) are associated with a variety of impacts on human well-being, health, and life-supporting systems. These vary from boosting the proliferation of vectors of diseases (e.g., mosquitos), to mental problems triggered by damage to properties and infrastructure. There is a great variety of literature about the strong links between climate change and health, while there is relatively less literature that specifically examines the health impacts of climate risks and extreme events. This paper is an attempt to address this knowledge gap, by compiling eight examples from a set of industrialised and developing countries, where such interactions are described. The policy implications of these phenomena and the lessons learned from the examples provided are summarised.

There are various climate risks that are caused or influenced by climate change. They are known to have a wide range of physical, economic, environmental and social impacts. Apart from damages to the physical environment, many climate risks (climate variability, extreme events and climate-related hazards) are associated with a variety of impacts on human well-being, health, and life-supporting systems. These vary from boosting the proliferation of vectors of diseases (e.g., mosquitos), to mental problems triggered by damage to properties and infrastructure. There is a great variety of literature about the strong links between climate change and health, while there is relatively less literature that specifically examines the health impacts of climate risks and extreme events. This paper is an attempt to address this knowledge gap, by compiling eight examples from a set of industrialised and developing countries, where such interactions are described. The policy implications of these phenomena and the lessons learned from the examples provided are summarised.

A significant number of patients with rheumatoid arthritis (RA) link the start of illness with psychological trauma or severe stress. Impaired mental health (IMH), defined as depression and anxiety with psychoneuroimmunological factors, can play a significant role in RA. The main objective of this research was to investigate the mutual correlation of IMH and RA activity, estimated by the laboratory and clinical parameters in RA patients. An open clinical prospective study that lasted for 6 months was designed. There were 72 patients included, 58 women and 14 men, aged 34 to 80 years and screened for mental health status. The study population was randomized following the Brief Symptoms Inventory (BSI) scale, comprised of 53 questions with a range from 0 (no symptoms) to 4 (severe). This mental test was done only once during the study. Following the results from the BSI scale, RA patients were divided into mentally stable and mentally unstable patients to investigate the influence of RA activity on mental health. The following laboratory and clinical parameters were analyzed: sex, age, erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), C-reactive protein (CRP), anti-cyclic citrullinated peptide (anti-CCP) antibody, and disease activity score (DAS28). All RA patients did not express extra-articular manifestations or Sjögren's syndrome. The chi-square test, ANOVA, Pearson's coefficient, and IBM Statistics - SPSS v19 were used. From a total of 72 RA patients, there were 44 mentally stable and 28 mentally unstable patients. All patients had either moderate or severe active disease. The only significant correlation of IMH and activity of RA was found in CRP and DAS28, but no significance was observed in ESR, RF, and anti-CCP. The DAS28 showed high disease activity with an average of 5.3 and CRP of 20.9 mg/L in patients with unstable mental health compared to stable mental health patients, where RA was associated with a moderate DAS average value of 4.35 and

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

To determine if daily respiratory status improved more in extremely low gestational age (GA) premature infants after diuretic exposure compared with those not exposed in modern neonatal intensive care units. The Prematurity and Respiratory Outcomes Program (PROP) was a multicenter observational cohort study of 835 extremely premature infants, GAs of 23 0/7 -28 6/7 weeks, enrolled in the first week of life from 13 US tertiary neonatal intensive care units. We analyzed the PROP study daily medication and respiratory support records of infants ≤34 weeks postmenstrual age. We determined whether there was a temporal association between the administration of diuretics and an acute change in respiratory status in premature infants in the neonatal intensive care unit, using an ordered categorical ranking of respiratory status. Infants in the diuretic exposed group of PROP were of lower mean GA and lower mean birth weight (P respiratory status before receiving diuretics) that the exposed infants were on a higher level of respiratory support was significantly greater (OR, >1) for each day after the initial day of diuretic exposure. Our analysis did not support the ability of diuretics to substantially improve the extremely premature infant's respiratory status. Further study of both safety and efficacy of diuretics in this setting are warranted. Clinicaltrials.gov: NCT01435187. Published by Elsevier Inc.

Doppler ultrasonography of the lower extremity arteries is a valuable technique, although it is less frequently indicated for peripheral arterial disease than for deep vein thrombosis or varicose veins. Ultrasonography can diagnose stenosis through the direct visualization of plaques and through the analysis of the Doppler waveforms in stenotic and poststenotic arteries. To perform Doppler ultrasonography of the lower extremity arteries, the operator should be familiar with the arterial anatomy of the lower extremities, basic scanning techniques, and the parameters used in color and pulsed-wave Doppler ultrasonography.

Independent investigations have shown that socioeconomic status (SES) and learned helplessness (LH) are associated with poor disease outcome in patients with rheumatoid arthritis (RA). Our aim was to investigate the cross-sectional relationship between SES, LH, and disease outcome in patients with recent-onset inflammatory polyarthritis (IP), the broader group of conditions of which RA is the major constituent. SES was measured using the Index of Multiple Deprivation 2007 for 553 patients consecutively recruited to the Norfolk Arthritis Register. Patients also completed the Rheumatology Attitudes Index, a measure of LH. SES and LH were investigated as predictors of disease outcome (functional disability [Health Assessment Questionnaire (HAQ)] and disease activity [Disease Activity Score in 28 joints]) in a regression analysis, adjusted for age, sex, and symptom duration. The role of LH in the relationship between SES and disease outcome was then investigated. Compared to patients of the highest SES, those of the lowest SES had a significantly worse outcome (median difference in HAQ score 0.42; 95% confidence interval [95% CI] 0.08, 0.75). Compared to patients with normal LH, patients with low LH had a significantly better outcome and patients with high LH had a significantly worse outcome (median difference in HAQ score 1.12; 95% CI 0.82, 1.41). There was a significant likelihood that LH mediated the association between SES and disease outcome (P = 0.04). LH is robustly associated with cross-sectional disease outcome in patients with IP, and appears to mediate the relationship between SES and disease outcome. As LH is potentially modifiable, these findings have potential clinical implications. Copyright © 2012 by the American College of Rheumatology.

Full Text Available Rheumatic diseases of juxta-articular soft tissues (RDJAST (tendinitis, tenosynovitis, bursitis, etc. are one of the most common causes of disability and one the most common reasons for seeking medical advice. To manage patients with RDJAST is an important part of practising rheumatologists’ work. But unfortunately, the issues of diagnosis and therapy of this pathology have been relatively rarely discussed on the pages of Russian medical journals and at the scientific congresses and conferences of rheumatologists in recent years. This review is to refresh physicians’interest in this problem. Part 1 of this review briefly considers the general issues relating to the epidemiology, pathogenesis, and diagnosis of RDJAST of the upper extremity, such as rotator cuff tendinitis, lateral and medial epicondylitis, stenosing flexor tenosynovitis, de Quervain’s syndrome, and carpal tunnel syndrome.

Chronic obstructive pulmonary disease is the fifth leading cause of mortality in the world. This study reviews diet as a risk or protective factor for chronic obstructive pulmonary disease, mechanisms of malnutrition, undernutrition consequences on body functioning and how to modulate nutritional status of patients with chronic obstructive pulmonary disease. Different dietary factors (dietary pattern, foods, nutrients) have been associated with chronic obstructive pulmonary disease and the course of the disease. Mechanical disadvantage, energy imbalance, disuse muscle atrophy, hypoxemia, systemic inflammation and oxidative stress have been reported to cause systemic consequences such as cachexia and compromise whole body functioning. Nutritional intervention makes it possible to modify the natural course of the disease provided that it is included in respiratory rehabilitation combining bronchodilators optimization, infection control, exercise and, in some patients, correction of hypogonadism. Diet, as a modifiable risk factor, appears more as an option to prevent and modify the course of chronic obstructive pulmonary disease. Reduction of mechanical disadvantage, physical training and anabolic agents should be used conjointly with oral nutrition supplements to overcome undernutrition and might change the prognosis of the disease in some cases. Major research challenges address the role of systemic inflammation and the best interventions for controlling it besides smoking cessation.

The management of some orthopaedic extremity injuries has changed over the past decade because of changing resource availability and the risks of complications. It is helpful to review the current literature regarding orthopaedic extremity emergencies and urgencies. The effects of the techniques of damage control orthopaedic techniques and the concept of the orthopaedic trauma room have also affected the management of these injuries. The available literature indicates that the remaining true orthopaedic extremity emergencies include compartment syndrome and vascular injuries associated with fractures and dislocations. Orthopaedic urgencies include open fracture management, femoral neck fractures in young patients treated with open reduction and internal fixation, and talus fractures that are open or those with impending skin compromise. Deciding when the definitive management of orthopaedic extremity injuries will occur has evolved as the concept of damage control orthopaedics has become more commonly accepted. Patient survival rates have improved with current resuscitative protocols. Definitive fixation of extremity injuries should be delayed until the patient's physiologic and extremity soft-tissue status allows for appropriate definitive management while minimizing the risks of complications. In patients with semiurgent orthopaedic injuries, the use of an orthopaedic trauma room has led to more efficient care of patients, fewer complications, and better time management for surgeons who perform on-call service for patients with traumatic orthopaedic injuries.

We introduce methodology from statistical extreme value theory to examine the ability of reanalysis-drive regional climate models to simulate past daily precipitation extremes. Going beyond a comparison of summary statistics such as 20-year return values, we study whether the most extreme precipitation events produced by climate model simulations exhibit correspondence to the most extreme events seen in observational records. The extent of this correspondence is formulated via the statistical concept of tail dependence. We examine several case studies of extreme precipitation events simulated by the six models of the North American Regional Climate Change Assessment Program (NARCCAP) driven by NCEP reanalysis. It is found that the NARCCAP models generally reproduce daily winter precipitation extremes along the Pacific coast quite well; in contrast, simulation of past daily summer precipitation extremes in a central US region is poor. Some differences in the strength of extremal correspondence are seen in the central region between models which employ spectral nudging and those which do not. We demonstrate how these techniques may be used to draw a link between extreme precipitation events and large-scale atmospheric drivers, as well as to downscale extreme precipitation simulated by a future run of a regional climate model. Specifically, we examine potential future changes in the nature of extreme precipitation along the Pacific coast produced by the pineapple express (PE) phenomenon. A link between extreme precipitation events and a "PE Index" derived from North Pacific sea-surface pressure fields is found. This link is used to study PE-influenced extreme precipitation produced by a future-scenario climate model run.

Non-human primates (NHPs) are phylogenetically close to humans, with many similarities in terms of physiology, anatomy, immunology, as well as neurology, all of which make them excellent experimental models for biomedical research. Compared with developed countries in America and Europe, China has relatively rich primate resources and has continually aimed to develop NHPs resources. Currently, China is a leading producer and a major supplier of NHPs on the international market. However, there are some deficiencies in feeding and management that have hampered China's growth in NHP research and materials. Nonetheless, China has recently established a number of primate animal models for human diseases and achieved marked scientific progress on infectious diseases, cardiovascular diseases, endocrine diseases, reproductive diseases, neurological diseases, and ophthalmic diseases, etc. Advances in these fields via NHP models will undoubtedly further promote the development of China's life sciences and pharmaceutical industry, and enhance China's position as a leader in NHP research. This review covers the current status of NHPs in China and other areas, highlighting the latest developments in disease models using NHPs, as well as outlining basic problems and proposing effective countermeasures to better utilize NHP resources and further foster NHP research in China.

Extreme fetal growth is associated with increased susceptibility to a range of adult diseases through an unknown mechanism of cellular memory. We tested whether heritable epigenetic processes in long-lived CD34+ hematopoietic stem/progenitor cells (HSPCs) showed evidence for re-programming associated with the extremes of fetal growth. Here we show that both fetal growth restriction and over-growth are associated with global shifts towards DNA hypermethylation, targeting cis-regulatory elements in proximity to genes involved in glucose homeostasis and stem cell function. We find a sexually dimorphic response; intrauterine growth restriction (IUGR) is associated with substantially greater epigenetic dysregulation in males, whereas large for gestational age (LGA) growth predominantly affects females. The findings are consistent with extreme fetal growth interacting with variable fetal susceptibility to influence cellular aging and metabolic characteristics through epigenetic mechanisms, potentially generating biomarkers that could identify infants at higher risk for chronic disease later in life.

Objective: To evaluate fluoroscopically-guided foam sclerotherapy with injection of domestic sodium morrhuate in treating lower extremity varices. Methods: A total of 30 cases (39 diseased lower limbs) with lower extremity varices were enrolled in this study. Under fluoroscopic guidance foam sclerotherapy with injection of domestic sodium morrhuate was carried out in all patients. The obstructed condition of the great saphenous vein was observed during the following three months. Results: The technical success was achieved in all 39 patients. The mean dose of foam sclerosant used for each diseased limb was 5.9 ml (3.4-8.2 ml). Disappearance of blood flow reflux in lower extremity vein immediately after the treatment was seen in 35 patients (90%). Three months after the therapy, vascular sonography showed that the great saphenous vein was obstructed, and no serious complications occurred. Conclusion: For the treatment of lower extremity varices, fluoroscopically-guided foam sclerotherapy with injection of domestic sodium morrhuate is safe and effective with satisfactory results. This technique is a newly-developed micro-invasive therapy for lower extremity varices. (authors)

Full Text Available Chronic obstructive pulmonary disease (COPD is characterized by both airway remodeling and parenchymal destruction. The identification of unique biomarker patterns associated with airway dominant versus parenchymal dominant patterns would support the existence of unique phenotypes representing independent biologic processes. A cross-sectional study was performed to examine the association of serum biomarkers with radiographic airway and parenchymal phenotypes of COPD.Serum from 234 subjects enrolled in a CT screening cohort was analyzed for 33 cytokines and growth factors using a multiplex protein array. The association of serum markers with forced expiratory volume in one second percent predicted (FEV1% and quantitative CT measurements of airway thickening and emphysema was assessed with and without stratification for current smoking status. Significant associations were found with several serum inflammatory proteins and measurements of FEV1%, airway thickening, and parenchymal emphysema independent of smoking status. The association of select analytes with airway thickening and emphysema was independent of FEV1%. Furthermore, the relationship between other inflammatory markers and measurements of physiologic obstruction or airway thickening was dependent on current smoking status.Airway and parenchymal phenotypes of COPD are associated with unique systemic serum biomarker profiles. Serum biomarker patterns may provide a more precise classification of the COPD syndrome, provide insights into disease pathogenesis and identify targets for novel patient-specific biological therapies.

2010-01-01

Background: Minimally invasive imaging techniques are increasingly used for clinical decision making in patients with peripheral arterial occlusive disease (PAOD). Purpose: To assess whether gadofosveset-enhanced three-dimensional (3D) magnetic resonance (MR) angiography could replace digital subtraction angiography (DSA) for the evaluation of lower-extremity PAOD. Material and Methods: Thirty patients with symptomatic PAOD underwent prospectively both MR angiography and DSA. Gadofosveset-enhanced 3D MR angiography was performed on a 1.5T system equipped with a peripheral angio matrix coil. Four blinded observers independently analyzed MR angiograms and DSA images. The lower arterial vascular system was divided into three anatomic segments (aortoiliac, femoropopliteal, infrapopliteal) for review. The status of each segment was graded as normal, stenosis less than 50%, stenosis greater than 50%, or occluded and/or aneurismatic. Principal and secondary lesions were reported. Results: Although interobserver agreement for both was excellent, it was higher for DSA (?=0.92) than for MR angiography (?=0.86) for reporting the principal and secondary lesions in all segments. For different anatomic locations, the interobserver agreement of MR angiography and DSA was as follows: aortoiliac (?=0.93, k=0.95), femoropopliteal (?=0.86, k=0.90), and infrapopliteal (?=0.78, k=0.85). The lowest agreement was found for MR angiography on infrapopliteal segments (?=0.78). In four (13.3%) cases, MR angiography showed lesions that were not found by DSA. Five (16.6%) aneurysm cases, not observed by DSA, were shown by MR angiography. Conclusion: Gadofosveset-enhanced 3D MR angiography can be proposed for first-line imaging in the management of lower-limb PAOD patients and permits the selective use of DSA as a second-line examination when MR angiography fails or in an endovascular approach
Degree of glutathione deficiency and redox imbalance depend on subtype of mitochondrial disease and clinical status.

Full Text Available Mitochondrial disorders are associated with decreased energy production and redox imbalance. Glutathione plays a central role in redox signaling and protecting cells from oxidative damage. In order to understand the consequences of mitochondrial dysfunction on in vivo redox status, and to determine how this varies by mitochondrial disease subtype and clinical severity, we used a sensitive tandem mass spectrometry assay to precisely quantify whole blood reduced (GSH and oxidized (GSSG glutathione levels in a large cohort of mitochondrial disorder patients. Glutathione redox potential was calculated using the Nernst equation. Compared to healthy controls (n = 59, mitochondrial disease patients (n = 58 as a group showed significant redox imbalance (redox potential -251 mV ± 9.7, p<0.0001 with an increased level of oxidation by ∼ 9 mV compared to controls (-260 mV ± 6.4. Underlying this abnormality were significantly lower whole blood GSH levels (p = 0.0008 and GSH/GSSG ratio (p = 0.0002, and significantly higher GSSG levels (p<0.0001 in mitochondrial disease patients compared to controls. Redox potential was significantly more oxidized in all mitochondrial disease subgroups including Leigh syndrome (n = 15, electron transport chain abnormalities (n = 10, mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (n = 8, mtDNA deletion syndrome (n = 7, mtDNA depletion syndrome (n = 7, and miscellaneous other mitochondrial disorders (n = 11. Patients hospitalized in metabolic crisis (n = 7 showed the greatest degree of redox imbalance at -242 mV ± 7. Peripheral whole blood GSH and GSSG levels are promising biomarkers of mitochondrial dysfunction, and may give insights into the contribution of oxidative stress to the pathophysiology of the various mitochondrial disorders. In particular, evaluation of redox potential may be useful in monitoring of clinical status or response to redox-modulating therapies in clinical trials.

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.

Moderately elevated plasma/serum triglycerides (2-10 mmol/l) signalize increased risk for cardiovascular disease or presence of non-alcoholic steatohepatitis. Extremely elevated triglycerides (more than 10 mmol/l) signalize increased risk for pancreatitis and lipemia retinalis. The concentration of triglycerides is regulated by many genetic and nongenetic factors. Extremely elevated triglycerides not provoked by nutritional factors, especially inappropriate alcohol intake are more likely to have a monogenic cause. On the contrary, mildly to moderately elevated triglycerides are often caused by polygenic disorders; these could be also associated with central obesity, insulin resistance, and diabetes mellitus. Concentration of triglycerides is also closely interconnected with presence of atherogenic remnant lipoproteins, impaired reverse cholesterol transport and more atherogenic small LDL particles. In general, there is tight association between triglycerides and many other metabolic factors including intermediate products of lipoprotein metabolism which are frequently atherogenic. Therefore, reliable evaluation of the independent role of triglycerides especially in atherosclerosis and cardiovascular disease is difficult. In individual cases values of HDL cholesterol, non-HDL cholesterol (total minus HDL cholesterol), non-HDL/nonLDL cholesterol (total minus HDL minus LDL cholesterol, especially in nonfasting status), atherogenic index of plasma and/or apolipoprotein B could help in decisions regarding aggressiveness of treatment.

End-stage renal disease and dialysis is commonly associated with poor outcomes after joint replacement surgery. The goal of this study was to evaluate postoperative complications in patients with less advanced chronic kidney disease undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA). Patients who underwent THA or TKA between 2004 and 2011 with stage 1, 2, or 3 chronic kidney disease were retrospectively reviewed via an electronic medical record. The authors compared 377 patients who had stage 1 to 2 chronic kidney disease with 402 patients who had stage 3 chronic kidney disease. No significant differences in 90-day readmission or revision rates were found between the stage 1 to 2 and stage 3 patient groups. For patients with stage 3 chronic kidney disease, the overall mortality rate was greater than that in patients with stage 1 to 2 chronic kidney disease. However, when adjusted for comorbid disease, no significant increases were seen in joint infection, readmission, or early revision between patients with stage 1 to 2 chronic kidney disease vs patients with stage 3 chronic kidney disease. The overall incidence of infection was high (3.5%) but far less than reported for patients with end-stage renal disease, dialysis, and kidney transplant. In conclusion, patients with stage 1, 2, or 3 chronic kidney disease may have a higher than expected rate of prosthetic joint infection (3.5%) after total joint arthroplasty. Patients with stage 3 chronic kidney disease are at higher risk for postoperative mortality compared with those with lesser stages of kidney disease. Copyright 2014, SLACK Incorporated.

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.

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.

In July 1981, investigations on parasites, diseases, and herd health status were conducted on sympatric populations of sika deer (Cervus nippon) and white-tailed deer (Odocoileus virginianus) from Blackwater National Wildlife Refuge (Maryland) and Chincoteague National Wildlife Refuge (Virginia) on the Delmarva Peninsula. Five adult deer of each species were collected from each location and subjected to thorough necropsy examinations and laboratory tests. White-tailed deer at both locations harbored protozoan, helminth, and arthropod parasites typically associated with this species throughout the southeastern United States. In contrast, sika deer at both locations harbored only light burdens of ticks, chiggers, and sarcocysts. Serologic tests for antibodies to seven infectious disease agents revealed evidence of exposure to bovine virus diarrhea (BVD) virus, infectious bovine rhinotracheitis virus, and parainfluenza3 virus in white-tailed deer, but only BVD virus in sika deer. At both locations the general health status of sika deer was superior to that of white-tailed deer.

Full Text Available Highly selective β-adrenoblockers (β-AB are used in pregnant women with cardiovascular diseases (arterial hypertension, arrhythmia, Marfan syndrome, hypertrophic cardiomyopathy. β-AB fall into the category C according to safety classification of Food and Drug Administration (US FDA. Their prescription in different clinical situations meets the principle of "risk–benefit". Fetus and newborn status should be monitored because β-AB can cause bradycardia, hypoglycemia, apnea and metabolic disorders. The risk of these side effects is extremely low, while β-AB clinical efficacy is high.

To investigate the nutritional status of patients before and after hematopoietic stem cell transplantation (HSCT), and explore optimal methods for assessing nutritional status in patients with hematological diseases. This cohort study enrolled 170 patients who were diagnosed with hematological diseases and underwent allogeneic HSCT in the Department of Hematology, Peking University People's Hospital between May 2011 and April 2013. We used fixed-point continuous sampling and four nutritional screening tools, Nutritional Risk Screening 2002 (NRS-2002), Mini Nutritional Assessment (MNA), Subjective Global Assessment (SGA) and Malnutrition Universal Screening Tools (MUST), in combination with body measurements, to extensively screen and evaluate nutritional risks and status in patients receiving HSCT before entering and after leaving laminar air flow rooms. After HSCT, patients had significant reduction in weight, hip circumference, waist-hip ratio, calf circumference, mid-upper arm circumference, and suprailiac skinfold thickness compared with pre-HSCT measurements. Before HSCT, NRS-2002 identified that 21.2% of patients were at nutritional risks, compared with 100% after HSCT. MUST indicated that before HSCT, 11.77% of patients were at high nutritional risk, compared with 59.63% after HSCT. MNA assessed that 0.06% of patients were malnourished before HSCT, compared with 19.27% after HSCT. SGA identified that before HSCT, 1.76% of patients had mild to severe malnutrition, which increased to 83.3% after HSCT. There is a significant increase in the nutritional risk and malnutrition in patients who received HSCT. Before HSCT, some patients already had nutritional risk or nutritional deficiencies, and prompt and close nutritional screening or assessment should be performed. The nutritional status of patients after HSCT was generally deteriorated compared with that before transplantation. Body measurements should be taken more frequently during the subsequent treatment

If a child's general health is compromised, care for his/her oral and dental health becomes an absolute necessity. Children with heart diseases require special dental care because of the risk of developing infective endocarditis. Was to evaluate the oral health status, parental oral health care knowledge of the pediatric cardiac patients and non cardiac group and infective endocarditis awareness among the parents of the cardiac group. Include a total of 50 children with heart diseases and 50 non-cardiac children aged 2-12 years were examined for dental caries index and simplified debris index. A structured, administered questionnaire for parents/caregivers about knowledge of infective endocarditis and oral health were used for data collection. Showed no statistically significant differences between the caries experience score for the two groups and oral health knowledge. Knowledge about Infective Endocarditis in parents of study group was very poor. Simplified Debris Index of age group 6-12 years was higher in study groups compared to the controls. Improvements should be made in educating parents and children on the importance of caries prevention and maintaining a good oral hygiene in prevention of infective endocarditis.

Objective: The clinical values of conventional phlebography via percutaneous dorsal pedal vein access with scalp puncture was compared with innovative phlebography via a percutaneous great saphenous approach with retained catheter in lower extremity for detection of venous diseases. Methods: Conventional and innovative phlebographies in lower extremity were performed in 34 suffering lower extremities of 30 patients, and the efficacy of the two methods was compared in demonstrating the venous diseases in lower extremities. Results: The rates of vascular display of the common iliac vein, the valve of saphenous-femoral vein and the first couple valve of femoral vein were 100%, 100% and 91.18% respectively with innovative phlebography while the rates of vascular display were 32.25%, 73.53% and 64.71% respectively with conventional phlebography. Iliac vein compression syndrome (IVCS), venous valvular disfunction of saphenous-femoral vein and the venous valvular disfunction of the first couple valve of femoral vein were shown in 14, 25 and 21 cases respectively by innovative phlebography, and in 3, 14 and 12 cases respectively by conventional phlebography in patients suffering from varicose veins and chronic swelling of the lower extremities. There was significant difference between the innovative and conventional phlebographies (P < 0.05). Conclusion: The innovative phlebography possesses a higher efficacy in diagnosing IVCS, venous valvular disfunctions of saphenous-femoral vein and the first couple valve of femoral vein compared with conventional method. It would be an alternative method to the conventional one or percutaneous femoral venous approach. (authors)

OBJECTIVE To determine the prevalence of unrecognized lower extremity peripheral arterial disease (PAD) among men and women aged 55 years and older in a general internal medicine (GIM) practice and to identify characteristics and functional performance associated with unrecognized PAD. DESIGN Cross-sectional. SETTING Academic medical center. PARTICIPANTS We identified 143 patients with known PAD from the noninvasive vascular laboratory, and 239 men and women aged 55 and older with no prior PAD history from a GIM practice. Group 1 consisted of patients with PAD consecutively identified from the noninvasive vascular laboratory (n = 143). Group 2 included GIM practice patients found to have an ankle brachial index less than 0.90, consistent with PAD (n = 34). Group 3 consisted of GIM practice patients without PAD (n = 205). MEASUREMENTS AND MAIN RESULTS Leg functioning was assessed with the 6-minute walk, 4-meter walking velocity, and Walking Impairment Questionnaire (WIQ). Of GIM practice patients, 14% had unrecognized PAD. Only 44% of patients in Group 2 had exertional leg symptoms. Distances achieved in the 6-minute walk were 1,130, 1,362, and 1,539 feet for Groups 1, 2, and 3, respectively, adjusting for age, gender, and race (P < .001). The degree of difficulty walking due to leg symptoms as reported on the WIQ was comparable between Groups 2 and 3 and significantly greater in Group 1 than Group 2. In multiple logistic regression analysis including Groups 2 and 3, current cigarette smoking was associated independently with unrecognized PAD (odds ratio [OR], 6.82; 95% confidence interval [95% CI], 1.55 to 29.93). Aspirin therapy was nearly independently associated with absence of PAD (OR, 0.37; 95% CI, 0.12 to 1.12). CONCLUSION Unrecognized PAD is common among men and women aged 55 years and older in GIM practice and is associated with impaired lower extremity functioning. Ankle brachial index screening may be necessary to diagnose unrecognized PAD in a GIM

Full Text Available Abstract Intracardiac thrombus in Behçet's disease is an extremely rare manifestation. We report two such cases. A 20-year-old man presented with dyspnoea, cough and haemoptysis. Right heart thrombus associated with pulmonary artery aneurysm and thromboembolism was identified by helical CT and transoesophageal echocardiography. The second case was a 29-year-old male admitted for fever and chest pain. A diagnosis of right atrial thrombosis associated with pulmonary embolism and hyperhomocysteinemia was made. Due to the absence of haemodynamic compromise, medical management consisting of immunosupressive and anticoagulation therapy was adopted which resulted in complete dissolution of the thrombus with dramatic clinical improvement in both cases of clinical status. Conclusion intracardiac thrombus is a rare complication of Behçet's disease. As shown in our patients, medical treatment should be considered as the first line.

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 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.

Full Text Available Objectives: The gingival and periodontal changes during pregnancy are well known. Gingivitis is the most prevalent oral manifestations associated with pregnancy. The hormonal and vascular changes that accompany pregnancy are known to exaggerate the inflammatory response to the local irritants. Hence, a study was designed to assess oral hygiene status, gingival status, periodontal status, and treatment needs (TNs among pregnant and nonpregnant women. Materials and Methods: A cross-sectional study was conducted among 120 pregnant and 120 nonpregnant women of 18–44 years age attending the Outpatient Department of Gynaecology and Obstetrics in Government Hospital of Belgaum city, Karnataka, India. The study consisted of an interview and oral examination. Type 3 examination was followed. Simplified Oral Hygiene Index (OHI-S, Gingival Index, and Community Periodontal Index and TNs Index were used to assess “oral hygiene status,” “gingival status,” and “periodontal status and TNs,” respectively. Results: The pregnant women showed poor oral hygiene with the mean OHI-S score as 2.68. Gingivitis was prevalent in almost all the pregnant and nonpregnant women. However, it was found more severe in pregnant women with mean gingival score as 1.25. A definite increase in gingivitis was found from Trimester II to Trimester III. The mean number of sextants showing healthy gingiva was significantly (P < 0.01 lower among pregnant women. Conclusions: Pregnant women showed poor oral hygiene, more gingival inflammation, and more periodontal disease as compared to nonpregnant women. The severity of gingivitis increased in Trimester III. Proper oral hygiene practice can prevent these diseases and further complications.

Rethinking status dystonicus.

Ruiz-Lopez, Marta; Fasano, Alfonso

2017-12-01

Status dystonicus is a movement disorder emergency that has been a source of controversy in terms of terminology, phenomenology, and management since it was first described in 1982. Here we argue that the current use of the term status dystonicus falls well short of the precision needed for either clinical or academic use. We performed a critical review on this topic, describing possible pathophysiological mechanisms and areas of uncertainties. This review also addresses the problems derived by the extreme clinical heterogeneity of this condition, as the lack of an objective criterion useful for the definition, or the fact that status dystonicus may present not only in the context of a known dystonic syndrome. We propose a new possible definition that includes not only dystonia but also other hyperkinetic movements in the wide range of movement disorders that can be seen during an episode. The new definition keeps the term status dystonicus and highlights the fact that this is a medical emergency based on the impairment of bulbar and/or respiratory function requiring hospital admission as the principal feature. Furthermore, the new definition should not consider as necessary unspecific features as patient's condition at baseline, the distribution of dystonia, occurrence of systemic symptoms such as fever or laboratory findings. We hope that this proposal will stimulate the debate on this subject among our peers, further developing a clinical and pathophysiological understanding of status dystonicus. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and Movement Disorder Society.

End-stage renal disease is a disease with a long duration, requiring patients to live with the limitations imposed by their condition. Stressors associated with this disease are demanding, with patients dependent on support from their social environment. Here, we aimed to show the influences of familial, social, economic, and marital status on quality of life in patients with end-stage renal disease. Patients (190 women/188 men) who were under hemodialysis treatment and on transplant wait lists were included in the study. To evaluate the quality of life, patients completed the Short Form 36 health survey questionnaire voluntarily while undergoing hemodialysis treatment. All Short Form 36 questionnaire components were analyzed separately, and all social, economic, and business life dimensions were examined with another questionnaire. Significant differences were observed between single and married patients regarding physical and mental health dimensions (P work showed better Short Form 36 scores in working patients (P marital statuses, in addition to the influence of disease adaptation, independently affected the well-being of patients with end-stage renal disease.

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 anorexia at the time of diagnosis was found in 30 (25%) patients with UC and 99 (39%) patients with CD. The prevalence of thinness was 31%, 35% and 24% in children with IBD, CD and UC, respectively, with a significantly higher prevalence of thinness in children with CD than in children with UC (P = 0.037) only in the age group of 10-17 years (P = 0.030). The prevalence of overweight was 16 %, 15% and 20 % in the children with IBD, CD and UC, respectively, indicating a higher prevalence in UC that was statistically significant only in the age group of 10-17 years (P = 0.020). A high proportion of children with IBD presented with overweight instead of the classical underweight. Awareness of this finding is important for patient care.
Autochthonous Chikungunya Transmission and Extreme Climate Events in Southern France.

Extreme precipitation events are increasing as a result of ongoing global warming, but controversy surrounds the relationship between flooding and mosquito-borne diseases. A common view among the scientific community and public health officers is that heavy rainfalls have a flushing effect on breeding sites, which negatively affects vector populations, thereby diminishing disease transmission. During 2014 in Montpellier, France, there were at least 11 autochthonous cases of chikungunya caused by the invasive tiger mosquito Aedes albopictus in the vicinity of an imported case. We show that an extreme rainfall event increased and extended the abundance of the disease vector Ae. albopictus, hence the period of autochthonous transmission of chikungunya. We report results from close monitoring of the adult and egg population of the chikungunya vector Ae. albopictus through weekly sampling over the entire mosquito breeding season, which revealed an unexpected pattern. Statistical analysis of the seasonal dynamics of female abundance in relation to climatic factors showed that these relationships changed after the heavy rainfall event. Before the inundations, accumulated temperatures are the most important variable predicting Ae. albopictus seasonal dynamics. However, after the inundations, accumulated rainfall over the 4 weeks prior to capture predicts the seasonal dynamics of this species and extension of the transmission period. Our empirical data suggests that heavy rainfall events did increase the risk of arbovirus transmission in Southern France in 2014 by favouring a rapid rise in abundance of vector mosquitoes. Further studies should now confirm these results in different ecological contexts, so that the impact of global change and extreme climatic events on mosquito population dynamics and the risk of disease transmission can be adequately understood.
How extreme is extreme hourly precipitation?

The importance of accurate representation of precipitation at fine time scales (e.g., hourly), directly associated with flash flood events, is crucial in hydrological design and prediction. The upper part of a probability distribution, known as the distribution tail, determines the behavior of extreme events. In general, and loosely speaking, tails can be categorized in two families: the subexponential and the hyperexponential family, with the first generating more intense and more frequent extremes compared to the latter. In past studies, the focus has been mainly on daily precipitation, with the Gamma distribution being the most popular model. Here, we investigate the behaviour of tails of hourly precipitation by comparing the upper part of empirical distributions of thousands of records with three general types of tails corresponding to the Pareto, Lognormal, and Weibull distributions. Specifically, we use thousands of hourly rainfall records from all over the USA. The analysis indicates that heavier-tailed distributions describe better the observed hourly rainfall extremes in comparison to lighter tails. Traditional representations of the marginal distribution of hourly rainfall may significantly deviate from observed behaviours of extremes, with direct implications on hydroclimatic variables modelling and engineering design.

A number of dog breeds suffer from welfare problems due to extreme phenotypes and high levels of inherited diseases but the popularity of such breeds is not declining. Using a survey of owners of two popular breeds with extreme physical features (French Bulldog and Chihuahua), one with a high load of inherited diseases not directly related to conformation (Cavalier King Charles Spaniel), and one representing the same size range but without extreme conformation and with the same level of disease as the overall dog population (Cairn Terrier), we investigated this seeming paradox. We examined planning and motivational factors behind acquisition of the dogs, and whether levels of experienced health and behavior problems were associated with the quality of the owner-dog relationship and the intention to re-procure a dog of the same breed. Owners of each of the four breeds (750/breed) were randomly drawn from a nationwide Danish dog registry and invited to participate. Of these, 911 responded, giving a final sample of 846. There were clear differences between owners of the four breeds with respect to degree of planning prior to purchase, with owners of Chihuahuas exhibiting less. Motivations behind choice of dog were also different. Health and other breed attributes were more important to owners of Cairn Terriers, whereas the dog's personality was reported to be more important for owners of French Bulldogs and Cavalier King Charles Spaniels but less important for Chihuahua owners. Higher levels of health and behavior problems were positively associated with a closer owner-dog relationship for owners of Cavalier King Charles Spaniels and Chihuahuas but, for owners of French Bulldogs, high levels of problems were negatively associated with an intention to procure the same breed again. In light of these findings, it appears less paradoxical that people continue to buy dogs with welfare problems.

Thrombocytosis is usually a casual finding in children. Reactive or secondary thrombocytosis is the more common form, being the infections diseases the most prevalent cause of it. Regarding the number of platelets there are four degrees of thrombocytosis; in its extreme degree the number of platelets exceeds 1,000,000/mm(3). We describe a case of extreme reactive thrombocytosis in a healthy 6-year-old child. He required critical care admission for diagnosis and treatment (maximum number of platelets 7,283,000/mm(3)). We review the different causes of thrombocytosis in childhood, the differential diagnosis, and the available treatments in case of extreme thrombocytosis.

Over one-third of breast cancer survivors experience upper extremity disability. Black women present with factors associated with greater upper extremity disability, including: increased body mass index (BMI), more advanced disease stage at diagnosis, and varying treatment type compared with Whites. No prior research has evaluated the relationship between race and upper extremity disability using validated tools and controlling for these factors. Data were drawn from a survey study among 610 women with stage I-III hormone receptor positive breast cancer. The disabilities of the arm, shoulder and hand (QuickDASH) is an 11-item self-administered questionnaire that has been validated for breast cancer survivors to assess global upper extremity function over the past 7 days. Linear regression and mediation analysis estimated the relationships between race, BMI and QuickDASH score, adjusting for demographics and treatment types. Black women (n = 98) had 7.3 points higher average QuickDASH scores than White (n = 512) women (p disability by 40 %. Even several years post-treatment, Black breast cancer survivors had greater upper extremity disability, which was partially mediated by higher BMIs. Close monitoring of high BMI Black women may be an important step in reducing disparities in cancer survivorship. More research is needed on the relationship between race, BMI, and upper extremity disability.

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 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

Future through the development of lower extremity perfusion CT soft ware programs suggest possible clinical applications.
Thermodynamics of extremal rotating thin shells in an extremal BTZ spacetime and the extremal black hole entropy

In a (2 +1 )-dimensional spacetime with a negative cosmological constant, the thermodynamics and the entropy of an extremal rotating thin shell, i.e., an extremal rotating ring, are investigated. The outer and inner regions with respect to the shell are taken to be the Bañados-Teitelbom-Zanelli (BTZ) spacetime and the vacuum ground state anti-de Sitter spacetime, respectively. By applying the first law of thermodynamics to the extremal thin shell, one shows that the entropy of the shell is an arbitrary well-behaved function of the gravitational area A+ alone, S =S (A+). When the thin shell approaches its own gravitational radius r+ and turns into an extremal rotating BTZ black hole, it is found that the entropy of the spacetime remains such a function of A+, both when the local temperature of the shell at the gravitational radius is zero and nonzero. It is thus vindicated by this analysis that extremal black holes, here extremal BTZ black holes, have different properties from the corresponding nonextremal black holes, which have a definite entropy, the Bekenstein-Hawking entropy S (A+)=A/+4G , where G is the gravitational constant. It is argued that for extremal black holes, in particular for extremal BTZ black holes, one should set 0 ≤S (A+)≤A/+4G;i.e., the extremal black hole entropy has values in between zero and the maximum Bekenstein-Hawking entropy A/+4 G . Thus, rather than having just two entropies for extremal black holes, as previous results have debated, namely, 0 and A/+4 G , it is shown here that extremal black holes, in particular extremal BTZ black holes, may have a continuous range of entropies, limited by precisely those two entropies. Surely, the entropy that a particular extremal black hole picks must depend on past processes, notably on how it was formed. A remarkable relation between the third law of thermodynamics and the impossibility for a massive body to reach the velocity of light is also found. In addition, in the procedure, it

Full Text Available 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.

Purpose: In this retrospective study, we report on outcomes and prognostic factors for patients treated with stereotactic radiosurgery (SRS) for breast cancer brain metastases. Methods and Materials: We identified 132 consecutive patients with breast cancer who were treated with SRS for brain metastases from January 2000 through June 2010. We retrospectively reviewed records of the 51 patients with adequate follow-up data who received SRS as part of the initial management of their brain metastases. Overall survival (OS) and time to central nervous system (CNS) progression from the date of SRS were calculated using the Kaplan-Meier method. Prognostic factors were evaluated using the Cox proportional hazards model. Results: Triple negative subtype was associated with CNS progression on univariate analysis (hazard ratio [HR] = 5.0, p = 0.008). On multivariate analysis, triple negative subtype (HR = 8.6, p = 0.001), Luminal B subtype (HR = 4.3, p = 0.03), and omission of whole-brain radiation therapy (HR = 3.7, p = 0.02) were associated with CNS progression. With respect to OS, Karnofsky Performance Status (KPS) {<=} 80% (HR = 2.0, p = 0.04) and progressive extracranial disease (HR = 3.1, p = 0.002) were significant on univariate analysis; KPS {<=} 80% (HR = 4.1, p = 0.0004), progressive extracranial disease (HR = 6.4, p < 0.0001), and triple negative subtype (HR = 2.9, p = 0.04) were significant on multivariate analysis. Although median survival times were consistent with those predicted by the breast cancer-specific Graded Prognostic Assessment (Breast-GPA) score, the addition of extracranial disease status further separated patient outcomes. Conclusions: Tumor subtype is associated with risk of CNS progression after SRS for breast cancer brain metastases. In addition to tumor subtype and KPS, which are incorporated into the Breast-GPA, progressive extracranial disease may be an important prognostic factor for OS.

Periodontitis is a risk factor for coronary heart disease (CHD). Both diseases are an inflammatory diseases and have the same potential pathogenic mechanisms. Interleukin-1β as a pro-inflammatory main cytokine, can be found in this both diseases. Gingival crevicular fluid (GCF) derived from the serum of gingival sulcus, affected by inflammatory mechanism and the amount of this fluid will increase in that situation. Objective: To analyze the relationship of interleukin-1β levels in gingival crevicular fluid (GCF) of CHD and non-CHD patients with periodontal status. Methods: Oral clinical examination (plaque index, bleeding on probing, pocket depth and clinical attachment loss) for 35 subjects with CHD and 35 non CHD were checked, laboratory test to measure the levels of Interleukin-1β was checked with enzyme-linked immunosorbent assay (ELISA). Results: There was no significant differences between interleukin-1β levels in CHD and non-CHD patients (p>0.05); there was no significant difference between the level of Interleukin-1β with periodontal status in CHD and control (non CHD) patients (p>0.05). Conclusions: levels of Interleukin-1β in CHD patients do not have a relationships with plaque index, pocket depth and clinical attachment loss, but has a relationships with bleeding on probing.

We estimate a dynamic multi-stage duration model to investigate how early detection of diabetes can delay the onset of lower extremity complications and death. We allow for partial observability of the disease stage, unmeasured heterogeneity, and endogenous timing of diabetes screening. Timely diagnosis appears important. We evaluate the effectiveness of two potential policies to reduce the monetary costs of frequent screening in terms of lost longevity. Compared to the status quo, the more restrictive policy yields an implicit value for an additional year of life of about $50,000, while the less restrictive policy implies a value of about $120,000.

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.

Full Text Available We evaluated the association of indices of paraoxonase (PON1 and oxidative status with subclinical cardiovascular disease (CVD in mixed-ancestry South Africans. Participants were 491 adults (126 men who were stratified by diabetes status and body mass index (BMI. Carotid intima-media thickness (CIMT was used as a measure of subclinical CVD. Indices of PON1 and oxidative status were determined by measuring levels and activities (paraoxonase and arylesterase of PON1, antioxidant activity (ferric reducing antioxidant power and trolox equivalent antioxidant capacity, and lipid peroxidation markers (malondialdehyde and oxidized LDL. Diabetic subjects (28.9% displayed a significant decrease in PON1 status and antioxidant activity as well as increase in oxidized LDL and malondialdehyde. A similar profile was apparent across increasing BMI categories. CIMT was higher in diabetic than nondiabetic subjects (P<0.0001 but showed no variation across BMI categories. Overall, CIMT correlated negatively with indices of antioxidant activity and positively with measures of lipid oxidation. Sex, age, BMI, and diabetes altogether explained 29.2% of CIMT, with no further improvement from adding PON1 and/or antioxidant status indices. Though indices of PON1 and oxidative status correlate with CIMT, their measurements may not be useful for identifying subjects at high CVD risk in this population.

Differential gene expression profiles were assessed by suppression-subtractive hybridization, dot blot, real-time polymerase chain reaction, and the comparative cycle threshold methods. Comparing ATBD to control samples, greater fold-increases of gene expression were observed for a number of chemotactic factors (CXCL1, CXCL3, IL8, MCP1, MIP1α. ATBD was also associated with higher IL1B gene expression, relative to controls. Among LTBI samples, gene expression of several chemotactic factors (CXCL2, CXCL3, IL8 was similarly elevated, compared to individuals with PTBD. Our results demonstrated that samples from participants with ATBD and LTBI have distinct gene expression profiles in response to ex vivo M. tuberculosis infection. These findings indicate the value in further characterizing the peripheral responses to M. tuberculosis challenge as a route to defining immune correlates of disease status or outcome.

Children with celiac disease (CD) are at risk for decreased bone mineral density (BMD) because of fat-soluble vitamin malabsorption, inflammation and/or under-nutrition. The study objective was to determine the interrelationships between vitamin K/D status and lifestyle variables on BMD in children and adolescents with CD at diagnosis and after 1 year on the gluten-free diet (GFD). Children and adolescents aged 3-17 years with biopsy proven CD at diagnosis and after 1 year on the GFD were studied. BMD was measured using dual-energy X-ray absorptiometry.

To determine the social class gradient in health in general Spain population and the health status of the Spanish Roma. The National Health Survey of Spanish Roma 2006 (sample size = 993 people; average age: 33.6 years; 53.1% women) and the National Health Surveys for Spain 2003 (sample size: 21,650 people; average age: 45.5 years; 51.2% women) and 2006 (sample size: 29,478 people; average age: 46 years; 50.7% women) are compared. Several indicators were chosen: self-perceived health, activity limitation, chronic diseases, hearing and sight problems, caries, and obesity. Analysis was based on age-standardised rates and logistic regression models. According to most indicators, Roma's health is worse than that of social class IV-V (manual workers). Some indicators show a remarkable difference between Roma and social class IV-V: experiencing three or more health problems, sight problems, and caries, in both sexes, and hearing problems and obesity, in women. Roma people are placed on an extreme position on the social gradient in health, a situation of extreme health inequality.

Evidence has suggested that periodontal disease is associated with an increased risk of various adverse pregnancy and birth outcomes. However, several large clinical randomized controlled trials failed to demonstrate periodontal therapy during pregnancy reduced the incidence of adverse pregnancy and birth outcomes. It has been suggested that the pre-conception period may be an optimal period for periodontal disease treatment rather than during pregnancy. To date, no randomized controlled trial (RCT) has examined if treating periodontal disease before pregnancy reduces adverse birth outcomes. This study aims to examine if the pre-conception treatment of periodontal disease will lead to improved periodontal status during late pregnancy and subsequent birth outcomes. A sample of 470 (235 in each arm of the study) pre-conception women who plan to conceive within one year and with periodontal disease will be recruited for the study. All participants will be randomly allocated to the intervention or control group. The intervention group will receive free therapy including dental scaling and root planning (the standard therapy), supragingival prophylaxis, and oral hygiene education. The control group will only receive supragingival prophylaxis and oral hygiene education. Women will be followed throughout their pregnancy and then to childbirth. The main outcomes include periodontal disease status in late pregnancy and birth outcomes measured such as mean birth weight (grams), and mean gestational age (weeks). Periodontal disease will be diagnosed through a dental examination by measuring probing depth, clinical attachment loss and percentage of bleeding on probing (BOP) between gestational age of 32 and 36 weeks. Local and systemic inflammatory mediators are also included as main outcomes. This will be the first RCT to test whether treating periodontal disease among pre-conception women reduces periodontal disease during pregnancy and prevents adverse birth outcomes. If

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.
Risk of cardiovascular disease following radiation exposure

Trivedi, A.; Vlahovich, S.; Cornett, R.J.

2001-01-01

Excess radiation-induced cardiac mortalities have been reported among radiotherapy patients. Many case reports describe the occurrence of atherosclerosis following radiotherapy for Hodgkin's disease and breast cancer. Some case reports describe the cerebral infarction following radiotherapy to neck region, and of peripheral vascular disease of the lower extremities following radiotherapy to the pelvic region. The association of atomic bomb radiation and cardiovascular disease has been examined recently by incidence studies and prevalence studies of various endpoints of atherosclerosis; all endpoints indicated an increase of cardiovascular disease in the exposed group. It is almost certain that the cardiovascular disease is higher among atomic bomb survivors. However, since a heavy exposure of 10-40 Gy is delivered in radiotherapy and the bomb survivors were exposed to radiation at high dose and dose-rate, the question is whether the results can be extrapolated to individuals exposed to lower levels of radiation. Some recent epidemiological studies on occupationally exposed workers and population living near Chernobyl have provided the evidence for cardiovascular disease being a significant late effect at relatively low doses of radiation. However, the issue of non-cancer mortality from radiation is complicated by lack of adequate information on doses, and many other confounding factors (e.g., smoking habits or socio-economic status). This presentation will evaluate possible radiobiological mechanisms for radiation-induced cardiovascular disease, and will address its relevance to radiation protection management at low doses and what the impact might be on future radiation risk assessments.

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.

Individuals born extremely preterm are exposed to significant perinatal stresses that are associated with an increased risk of psychopathology. However, a paucity of longitudinal studies has prevented the empirical examination of long-term, dynamic effects of perinatal adversity on mental health. Here, internalizing and externalizing problems from adolescence through adulthood were compared in individuals born at extremely low birth weight (ELBW; 2,500 g). Internalizing and externalizing data were collected over 20 years in three waves, during adolescence, young adulthood, and adulthood. Growth models were used to compare longitudinal trajectories in a geographically based sample of 151 ELBW survivors and 137 NBW control participants born between 1977 and 1982 matched for age, sex, and socioeconomic status at age 8. After adjusting for sex, socioeconomic and immigrant status, and family functioning, ELBW survivors failed to show the normative, age-related decline in internalizing problems over time relative to their NBW peers (β = .21; p Self-esteem (but not physical health, IQ, or maternal mood) partially mediated the association between ELBW status and internalizing problems. Extremely low birth weight survivors experienced a blunting of the expected improvement in depression and anxiety from adolescence to adulthood. These findings suggest that altered physiological regulatory systems supporting emotional and cognitive processing may contribute to the maintenance of internalizing problems in this population. © 2018 Association for Child and Adolescent Mental Health.

Full Text Available Introduction: The periodontal disease represents a malady characterized by an extremely high incidence. The manifestations and evolution of the periodontal diseases vary for each form in part, being influenced by systemic and local risk factors. Scope of the study: To evaluate the periodontal status on a group of patients, versus the syste‐ mic and local factors. Materials and method: The study was performed on a group of 170 patients, whose odonto‐periodontal status was evaluated by strict clinical and paraclinical examinations, on establishing the inflammation indices and the periodontal diagnosis. Results: The main cause of the analysis was gingival ble‐ eding; an increased number of smokers was registered among the patients. Out of the local factors, especially important were edentations and malocclusions. Also, a higher number of aggressive generalized periodontites has been noticed. Discussion: The forms of the periodontal diseases are obviously influenced by the systemic context, while the forms of localized chronic periodontitis associa‐ ted with generalized chronic gingivitis reflect the role pla‐ yed by the local risk factors. Conclusions: Stress and smoking represent significant risk factors in the installation of periodontal pathology, with a really alarming preva‐ lence. The aggressive forms of periodontitis showed a higher frequency than that recorded in literature.

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.
Extreme insular dwarfism evolved in a mammoth.

The insular dwarfism seen in Pleistocene elephants has come to epitomize the island rule; yet our understanding of this phenomenon is hampered by poor taxonomy. For Mediterranean dwarf elephants, where the most extreme cases of insular dwarfism are observed, a key systematic question remains unresolved: are all taxa phyletic dwarfs of a single mainland species Palaeoloxodon antiquus (straight-tusked elephant), or are some referable to Mammuthus (mammoths)? Ancient DNA and geochronological evidence have been used to support a Mammuthus origin for the Cretan 'Palaeoloxodon' creticus, but these studies have been shown to be flawed. On the basis of existing collections and recent field discoveries, we present new, morphological evidence for the taxonomic status of 'P'. creticus, and show that it is indeed a mammoth, most probably derived from Early Pleistocene Mammuthus meridionalis or possibly Late Pliocene Mammuthus rumanus. We also show that Mammuthus creticus is smaller than other known insular dwarf mammoths, and is similar in size to the smallest dwarf Palaeoloxodon species from Sicily and Malta, making it the smallest mammoth species known to have existed. These findings indicate that extreme insular dwarfism has evolved to a similar degree independently in two elephant lineages.

To determine how adult juvenile idiopathic arthritis (JIA) patients fulfil classification criteria for adult rheumatic diseases, evaluate their outcomes and determine clinical predictors of inactive disease, functional status and damage. Patients with JIA registered on the Rheumatic Diseases Portuguese Register (Reuma.pt) older than 18 years and with more than 5 years of disease duration were included. Data regarding sociodemographic features, fulfilment of adult classification criteria, Health Assessment Questionnaire, Juvenile Arthritis Damage Index-articular (JADI-A) and Juvenile Arthritis Damage Index-extra-articular (JADI-E) damage index and disease activity were analysed. 426 patients were included. Most of patients with systemic JIA fulfilled criteria for Adult Still's disease. 95.6% of the patients with rheumatoid factor (RF)-positive polyarthritis and 57.1% of the patients with RF-negative polyarthritis matched criteria for rheumatoid arthritis (RA). 38.9% of the patients with extended oligoarthritis were classified as RA while 34.8% of the patients with persistent oligoarthritis were classified as spondyloarthritis. Patients with enthesitis-related arthritis fulfilled criteria for spondyloarthritis in 94.7%. Patients with psoriatic arthritis maintained this classification. Patients with inactive disease had lower disease duration, lower diagnosis delay and corticosteroids exposure. Longer disease duration was associated with higher HAQ, JADI-A and JADI-E. Higher JADI-A was also associated with biological treatment and retirement due to JIA disability and higher JADI-E with corticosteroids exposure. Younger age at disease onset was predictive of higher HAQ, JADI-A and JADI-E and decreased the chance of inactive disease. Most of the included patients fulfilled classification criteria for adult rheumatic diseases, maintain active disease and have functional impairment. Younger age at disease onset was predictive of higher disability and decreased the

Extremely high concentration of folates in premature newborns: case reports. Folates are a group of water soluble compounds, which are important for metabolic processes in human body. These are important during periods of rapid cell growth. The most accurate indicator of long-term folate level status in the body is the determination of red blood cell (RBC) folate concentrations. The optimal level of RBC folate is not known in neonatal period. Authors discuss the reasons for extremely high level of RBC folate concentrations. In our work we present the cases of two premature newborns with extremely high level of RBC folate concentrations, which were analyzed immunochemically on the first day of life and after six weeks of life. In both cases we measured RBC folate concentrations on the 1st day of life. After 6 weeks we found extremely high RBC folate concentration level (5516.67 ng/ml) in the first case after RBC transfusions. In second case after two months of life the RBC folate concentration level was doubled (2335.1 ng/ml) until 24 hours after RBC transfusion compared to levels after birth. The normal range of RBC folate values vary in newborns. The upper limit of daily dose of folic acid in pregnancy and neonatal period is not known. On the other hand it is an easily excreted water-soluble vitamin but in premature newborn it can lead to the disruption of metabolic balance and slow its degradation. Some factors can have an impact on RBC folate concentration. Blood transfusion can be one of the main influences on RBC folate concentration. To clarify these mechanisms further studies are required (Ref. 29).

Full Text Available In this article, we review the present status of experimental techniques under extreme conditions of high temperature and high pressure used for inelastic X-ray scattering (IXS experiments of liquid metals, semiconductors, molten salts, molecular liquids, and supercritical water and methanol. For high temperature experiments, some types of single-crystal sapphire cells were designed depending on the temperature of interest and the sample thickness for the X-ray transmission. Single-crystal diamond X-ray windows attached to the externally heated high-pressure vessel were used for the IXS experiment of supercritical water and methanol. Some typical experimental results are also given, and the perspective of IXS technique under extreme conditions is discussed.

Elevated mortality associated with high ambient temperatures in summer represents one of the main impacts of weather extremes on human society. Increases in cardiovascular mortality during heat waves have been reported in many European countries; much less is known about which particular cardiovascular disorders are most affected during heat waves, and whether similar patterns are found for morbidity (hospital admissions). Relatively less understood is also cold-related mortality and morbidity in winter, when the relationships between weather and human health are more complex, less direct, and confounded by other factors such as epidemics of influenza/acute respiratory infections. The present study analyses relationships between temperature extremes and cardiovascular morbidity and mortality. We make use of the datasets on hospital admissions and daily mortality in the population of the Czech Republic (about 10.3 million) over 1994-2009. The data have been standardized to remove the effects of the long-term trend and the seasonal and weekly cycles. Periods when the morbidity/mortality data were affected by epidemics of influenza and other acute respiratory infections have been removed from the analysis. We use analogous definitions for hot and cold spells based on quantiles of daily average temperature anomalies, which allows for a comparison of the findings for summer hot spells and winter cold spells. The main aims of the study are (i) to identify deviations of mortality and morbidity from the baseline associated with hot and cold spells, (ii) to compare the hot- and cold-spell effects for individual cardiovascular diseases (e.g. ischaemic heart disease I20-I25, cerebrovascular disease I60-I69, hypertension I10, aterosclerosis I70) and to identify those diagnoses that are most closely linked to temperature extremes, (iii) to identify population groups most vulnerable to temperature extremes, and (iv) to compare the links to temperature extremes for morbidity and

In hospitalized children with a chronic disease, malnutrition was associated with a lower subjective health status. In outpatient children with a chronic disease attending special schools, this association has never been studied. The aim of this study was to assess the association between nutritional status and subjective health status in chronically ill children attending special schools. Overall, 642 children, median age 9.8 years (IQR 7.7-11.5), 60 % male, 72 % Caucasian, were included in this prospective study in nine special schools for chronically ill children in the Netherlands. Overall malnutrition was assessed as: acute malnutrition (nutritional risk-screening tool STRONGkids. Subjective health status was assessed with EQ-5D. Overall, 16 % of the children had overall malnutrition: 3 % acute and 13 % chronic malnutrition. Nurses reported 'some/severe problems' on the health status dimensions mobility (15 %), self-care (17 %), usual activities (19 %), pain/discomfort (22 %), and anxiety/depression (22 %) in chronically ill children. Their mean visual analogue scale score (VAS) was 73.0 (SD 11.1). Malnutrition, medication usage, and younger age explained 38 % of the variance of the VAS score. The presence of overall malnutrition in chronically ill children attending special schools was associated with lower subjective health status, especially in younger children and in those with chronic medication usage. Therefore, it is important to develop and use profile-screening tools to identify these children.

Purpose: The impact of delayed adjuvant radiotherapy in patients treated by surgical resection for peripheral or torso soft tissue sarcoma has not been well characterized. We retrospectively examined this issue in an institutional patient cohort. Methods and Materials: One hundred two adult patients were treated at the University of Washington Medical Center between 1981 and 1998 with postoperative radiotherapy for cure of a newly diagnosed soft tissue sarcoma. Of this group, 58 patients had primary intermediate- or high-grade disease of the extremity or torso (50 extremity/8 torso). Tumor histology was predominantly malignant fibrohistiocytoma, synovial cell sarcoma, and leiomyosarcoma. The group was dichotomized according to time interval from definitive resection to the start of adjuvant radiation. Twenty-six patients had a short delay, defined as <4 months, and 32 patients had a long delay of ≥4 months. Both groups were balanced with regard to site, size, margin status, and tumor depth; however, the long-delay group had a larger proportion of high histologic grade lesions and was treated more frequently with chemotherapy (31/32 [97%] for long-delay patients vs. 14/26 [54%] for short-delay patients). Median follow-up was 49.5 months (range: 7-113 months). Median follow-up for patients still alive was 54 months (range: 9-113 months). Survival outcomes were estimated by the Kaplan-Meier method. Results: Overall local relapse-free survival at 5 years from the time of definitive resection was 74%. On univariate analysis, estimated 5-year local relapse-free survival was significantly improved in the short-delay group (88% vs. 62% for the long-delay group, p = 0.048 by log rank). Overall distant relapse-free survival, disease-free survival, and overall survival at 5 years were 77%, 68%, and 86%, respectively. These survival outcomes were statistically equivalent in both radiation delay groups. There was no evidence to suggest that delaying adjuvant systemic therapy

Objectives To elucidate the association between antiplatelet use in patients with non-haemorrhagic moyamoya disease before hospital admission and good functional status on admission in Japan. Design Retrospective, multicentre, non-randomised, observational study. Setting Nationwide registry data in Japan. Participants A total of 1925 patients with non-haemorrhagic moyamoya disease admitted between 1 April 2012 and 31 March 2014 in Japan. Main outcome measure We performed propensity score-matched analysis to examine the association between prehospital antiplatelet use and no significant disability on hospital admission, as defined by a modified Rankin Scale score of 0 or 1. Results Propensity-matched patients who received prehospital antiplatelet drugs were associated with a good outcome on hospital admission (OR adjusted for all covariates, 3.82; 95% CI 1.22 to 11.99) compared with those who did not receive antiplatelet drugs prior to hospital admission. Conclusions Prehospital antiplatelet use was significantly associated with good functional status on hospital admission among patients with non-haemorrhagic moyamoya disease in Japan. Our results suggest that prehospital antiplatelet use should be considered when evaluating outcomes of patients with non-haemorrhagic moyamoya disease. PMID:27008684
Gastric Cancer: Current Status of Diagnosis and Treatment

2013-01-01

Gastric cancer is the second leading cause of death from malignant disease worldwide and most frequently discovered in advanced stages. Because curative surgery is regarded as the only option for cure, early detection of resectable gastric cancer is extremely important for good patient outcomes. Therefore, noninvasive diagnostic modalities such as evolutionary endoscopy and positron emission tomography are utilized as screening tools for gastric cancer. To date, early gastric cancer is being treated using minimally invasive methods such as endoscopic treatment and laparoscopic surgery, while in advanced cancer it is necessary to consider multimodality treatment including chemotherapy, radiotherapy, and surgery. Because of the results of large clinical trials, surgery with extended lymphadenectomy could not be recommended as a standard therapy for advanced gastric cancer. Recent clinical trials had shown survival benefits of adjuvant chemotherapy after curative resection compared with surgery alone. In addition, recent advances of molecular targeted agents would play an important role as one of the modalities for advanced gastric cancer. In this review, we summarize the current status of diagnostic technology and treatment for gastric cancer

Pangolins are unique placental mammals with eight species existing in the world, which have adapted to a highly specialized diet of ants and termites, and are of significance in the control of forest termite disaster. Besides their ecological value, pangolins are extremely important economic animals with the value as medicine and food. At present, illegal hunting and habitat destruction have drastically decreased the wild population of pangolins, pushing them to the edge of extinction. Captive breeding is an important way to protect these species, but because of pangolin's specialized behaviors and high dependence on natural ecosystem, there still exist many technical barriers to successful captive breeding programs. In this paper, based on the literatures and our practical experience, we reviewed the status and existing problems in captive breeding of pangolins, including four aspects, the naturalistic habitat, dietary husbandry, reproduction and disease control. Some recommendations are presented for effective captive breeding and protection of pangolins.

Abstract Pangolins are unique placental mammals with eight species existing in the world, which have adapted to a highly specialized diet of ants and termites, and are of significance in the control of forest termite disaster. Besides their ecological value, pangolins are extremely important economic animals with the value as medicine and food. At present, illegal hunting and habitat destruction have drastically decreased the wild population of pangolins, pushing them to the edge of extinction. Captive breeding is an important way to protect these species, but because of pangolin’s specialized behaviors and high dependence on natural ecosystem, there still exist many technical barriers to successful captive breeding programs. In this paper, based on the literatures and our practical experience, we reviewed the status and existing problems in captive breeding of pangolins, including four aspects, the naturalistic habitat, dietary husbandry, reproduction and disease control. Some recommendations are presented for effective captive breeding and protection of pangolins. PMID:26155072

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

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

To help workplace health promotion practitioners reach low-socioeconomic status workers at high risk for chronic diseases. We describe low-socioeconomic status workers' diseases, health status, demographics, risk behaviors, and workplaces, using data from the Behavioral Risk Factor Surveillance System, Medical Expenditure Panel Survey, and Bureau of Labor Statistics. Workers with household annual incomes less than $35,000, or a high school education or less, report more chronic diseases and lower health status. They tend to be younger, nonwhite, and have much higher levels of smoking and missed cholesterol screening. They are concentrated in the smallest and largest workplaces and in three low-wage industries that employ one-quarter of the population. To decrease chronic diseases among low-socioeconomic status workers, we need to focus workplace health promotion programs on workers in low-wage industries and small workplaces.

Statins therapy in the secondary prevention of coronary artery disease (CAD) is associated with a lower risk of adverse cardiovascular events. However, little is known regarding the association of elderly patients with nutritional risk on statin therapy. To investigate whether older patients with CAD who were at nutritional risk gain similar survival benefit from statins therapy as their counterparts without nutritional risk. We conducted a retrospective hospital-based cohort study among 1705 patients with CAD who were older than 65 years of age, using coronary heart disease database from 2008 to 2012. Nutritional status of included patients was gauged using the geriatric nutritional risk index. After stratification by nutritional status, the hazard of all-cause death was compared between those with or without statins therapy. Of the 1705 patients included in the study (mean age 72 years; 73% male), all-cause death occurred in 146 (9.2%) patients with statins use and in 33 (26.2%) patients without statins use. The rate of all-cause death was higher in patients not receiving statins irrespective of nutritional status. After adjustments for potential confounders, the HR with statins use was 0.33 (95% CI 0.20-0.55) in patients without nutritional risk and 0.47 (95% CI 0.22-1.00) in patients with nutritional risk. No interaction effect was detected between nutritional status and statins use in relation to all-cause death (P value for interaction effect 0.516). Despite of the patient's nutritional status, statins therapy as a secondary prevention in elderly CAD patients was associated with decreased risk of all-cause death.

A 72-year-old woman presented with first onset of seizure with no prior history of cognitive dysfunction. EEG revealed focal non-convulsive status epilepticus. MRI brain showed a left temporal non-enhancing lesion. Temporal pole biopsy showed acute neuronal necrosis and astrocyte hyperplasia together with extensive amyloid plaques and neurofibrillary tangles. Perivascular oligodendroglial hyperplasia was present. Postmortem examination revealed extensive plaque and tangle disease. Perivascular oligodendroglial hyperplasia was limited to the left temporal area. The presence of focal perivascular oligodendroglial hyperplasia in the left temporal cortex, combined with extensive plaque and tangle disease may have contributed to the focal status epilepticus in this patient. Although the presence of focal perivascular oligodendroglial hyperplasia has been reported in cases of temporal lobe epilepsy, it has not been reported as a cause of seizure in patients with Alzheimer\\'s disease previously. Further studies for clinical-pathologic correlation would be required to confirm this hypothesis.

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%.

Influence of socioeconomic and demographic status on spirometry testing in patients initiating medication targeting obstructive lung disease: a population-based cohort study

Science.gov (United States)

2013-01-01

Background Socioeconomic status is known to influence the prevalence, severity and mortality of obstructive lung diseases, but it is uncertain whether it affects the use of diagnostic spirometry in patients initiating treatment for these conditions. The objective of this paper was to examine a possible association between education, income, labour market affiliation, cohabitation status and having spirometry performed when initiating medication targeting obstructive pulmonary disease. Methods We conducted a population-based cohort study. Danish national registers were linked, retrieving data on prescriptions, spirometry testing, socioeconomic and demographic variables in all first time users of medication targeting obstructive lung disease in 2008. Results A total of 37,734 persons were included and approximately half of the cohort had spirometry performed. Among medication users under 65 years of age, being unemployed was significantly associated with reduced odds of having spirometry performed, the strongest association was seen in men (OR = 0.82, CI = 0.73-0.91). Medium income was associated with increased odds of having spirometry performed in men (OR = 1.18, CI = 1.06-1.30) and high educational level (>12 years) was associated with reduced odds of having spirometry performed in women (OR = 0.86, CI = 0.78-0.94). Cohabitation status was not associated with having spirometry performed. Among medication users over 65 years of age, living alone was associated with reduced odds of having spirometry performed among men (OR = 0.78, CI = 0.69-0.88). Conclusion Social inequity in spirometry testing among patients initiating medication targeting obstructive lung disease was confirmed in this study. Increased focus on spirometry testing among elderly men living alone, among the unemployed and among women with higher education is required when initiating medication. PMID:23768408

To determine the impact of neighbourhood income and maternal residence population density on mortality and various morbidities at discharge or transfer from the NICU among extremely preterm neonates (<27 weeks gestation) in Canada. Neighbourhood income level and residential status was derived using a postal code conversion file and census data. Multivariable logistic regression analysis was used to estimate the risk-adjusted odds ratio (AOR) of mortality and survival without major morbidities (chronic lung disease, necrotizing enterocolitis, severe intraventricular hemorrhage, and retinopathy of prematurity) among 2,752 extremely preterm infants admitted to 25 tertiary level neonatal intensive care units in Canada between 2007 and 2008. There were no significant differences between mothers from different neighbourhood income quintiles (Q1 = low; Q5 = high) and neonatal mortality AOR (95% confidence interval): Q1: 1.10 (0.74-1.62), Q2: 1.00 (0.67-1.49), Q3: 1.39 (0.93-2.07), Q4: 1.01 (0.67-1.52), Q5: 1 (reference); or survival without major morbidity: Q1: 1.01 (0.70-1.44), Q2: 0.84 (0.58-1.23), Q3: 0.85 (0.58-1.24), Q4: 0.92 (0.63-1.35), Q5: 1 (reference). There were no significant differences in mortality (AOR 1.14 [0.83-1.57]) or in survival without major morbidity (AOR 0.92 [0.67-1.26]) between infants of mothers residing in sparsely populated areas compared to densely populated areas. Maternal residence in a low-income neighbourhood or sparsely populated area was not associated with higher odds of mortality or survival free of major morbidities in extremely preterm infants.

Introduction Childhood allergic diseases may prevent affected children from achieving their academic potential. Potential mechanisms include absence from school due to illness and medical appointments. Experience of symptoms in classes or leisure time, and stigma associated with visible signs and symptoms, including skin disease, requirements for medication during school time or the need for specific diets, may also contribute to reduced educational attainment. Studies have investigated the association between specific allergic diseases and educational attainment. The aim of this study is to systematically review the literature on allergic diseases, educational attainment and occupational status, and if possible, calculate meta-analytic summary estimates for the associations. Methods Systematic electronic searches in Medline, EMBASE, Cochrane, Cumulative Index to Nursing & Allied Health Literature (CINAHL), PsycINFO and education Resources Information Center (ERIC); hand search in reference lists of included papers and conference reports; search for unpublished studies in clinical trial registers and the New York Academy of Medicine Grey Literature Report; data extraction; and study quality assessment (Newcastle-Ottawa Scale) will be performed. Analysis Data will be summarised descriptively, and meta-analysis including meta-regression to explore sources of heterogeneities will be performed if possible. Ethics and dissemination Dissemination in a peer-reviewed, open-access, international scientific journal is planned. PROSPERO registration number CRD42017058036. PMID:29025838

Genetic and epigenetic alterations contribute to the biological and clinical characteristics of myelodysplastic syndromes (MDS), but a role for socioeconomic environment remains unclear. Here, socioeconomic status (SES) for 283 MDS patients was estimated using the Scottish Index of Multiple Deprivation tool. Indices were assigned to quintile categorical indicators ranked from SES1 (lowest) to SES5 (highest). Clinicopathological features and outcomes between SES quintiles containing 15%, 20%, 19%, 30% and 16% of patients were compared. Prognostic scores identified lower-risk MDS in 82% of patients, with higher-risk disease in 18%. SES quintiles did not associate with age, gender, cytogenetics, International Prognostic scores or, in sub-analysis (n = 95), driver mutations. The odds ratio of a diagnosis of refractory anaemia was greater than other MDS sub-types in SES5 (OR 1·9, P = 0·024). Most patients (91%) exclusively received supportive care. SES did not associate with leukaemic transformation or cause of death. Cox regression models confirmed male gender (P < 0·05), disease-risk (P < 0·0001) and age (P < 0·01) as independent predictors of leukaemia-free survival, with leukaemic transformation an additional determinant of overall survival (P = 0·07). Thus, if access to healthcare is equitable, SES does not determine disease biology or survival in MDS patients receiving supportive treatment; additional studies are required to determine whether outcomes following disease-modifying therapies are influenced by SES. © 2016 John Wiley & Sons Ltd.

In treated hypertensives, extreme-dippers with stable coronary artery disease (CAD) exhibit more severe nighttime cardiac ischemia than dippers. After excluding confounding factors such as diabetes, CAD or chronic kidney disease (CKD), we assessed whether subendocardial viability, determined by the Buckberg index, was more significantly impaired in extreme-dippers than in dippers. Two hundred thirteen consecutive treated hypertensives (156 dippers, 57 extreme-dippers), were included. After 24-hour ambulatory blood pressure (BP) monitoring, patients underwent radial applanation tonometry (with determination of: subendocardial viability ratio [SEVR], central augmentation index [AIx], and pulse pressure amplification [PPamp]), carotid-femoral pulse wave velocity (cfPWV) measurement, and cycle ergometer stress testing. Extreme-dippers showed higher cfPWV (8.99 ± 2.16 vs. 8.29 ± 1.69 m/s, P = 0.014), higher AIx (29.7 ± 9.4 vs. 26.4 ± 10.4%, P = 0.042), lower PPamp (1.22 ± 0.14 vs. 1.30 ± 0.15, P < 0.001), lower SEVR (146 ± 23% vs. 157 ± 26%, P = 0.007), and lower nighttime diastolic BP (DBP) (70 ± 9 vs. 75 ± 9 mm Hg, P < 0.001) than dippers. SEVR and cfPWV were inversely correlated. Among extreme-dippers, women exhibited lower SEVR (138 ± 21% vs. 161 ± 23%, P = 0.004), PPamp (1.16 ± 0.10 vs. 1.31 ± 0.15, P < 0.001), and nighttime DBP (67 ± 8 mm Hg vs. 72 ± 8 mm Hg, P = 0.017) than men. Extreme-dipper treated hypertensives with no history of CAD, diabetes or CKD, present increased aortic stiffness and low PPamp. Furthermore, this is the first demonstration of the greater likelihood of these patients to exhibit impaired subendocardial viability compared to dippers. Extreme-dipper hypertensive patients, women in particular, may have a significantly higher risk of silent myocardial ischemia, thus justifying systematic screening. © American Journal of Hypertension, Ltd 2017.

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.

2012-01-01

Objective: To explore the clinical significance of retrograde access for the interventional treatment of lower extremity arterial occlusive diseases when the occluded segment of lower extremity artery could not be reached through antegrade access. Methods: Twenty-seven cases (male 17, female 10; age range 32-89 years) were retrospectively investigated, including 18 with lower limb arteriosclerosis obliterans, 7 with diabetic foot and 2 with thromboangiitis obliterans. According to the Fontaine staging, 6 cases were classified as Fontaine Ⅱ, 11 were classified as Fontaine Ⅲ and 10 were classified as Fontaine Ⅳ. All cases underwent endovascular operation through antegrade access first with an attempt to cross the occlusive segment, but in vain. So retrograde access was tried via puncture of pedis dorsalis or posterior tibial artery or exposure of lateral branches of posterior tibial artery, peroneal artery or dorsal artery by open surgery,which followed by Percutaneous transluminal angiography and (or) stenting. Results: The operation through retrograde access was successful in all cases with obvious improvement of ischemic symptoms. Hematoma at the puncture site occurred in 3 patients, and paresthesia of toes occurred in 1 after dorsalis pedis arteriotomy. No severe perioperative complication occurred. The average ankle brachial index increased from 0.37 ± 0.11 preoperatively to 0.85 ± 0.12 postoperatively. Conclusions: Retrograde access could be used as an alternative strategy in lower extremity arterial occlusive diseases when the occluded segment could not reach through antegrade access. (authors)

Overview of the biology of extreme events

Gutschick, V. P.; Bassirirad, H.

2008-12-01

Extreme events have, variously, meteorological origins as in heat waves or precipitation extremes, or biological origins as in pest and disease eruptions (or tectonic, earth-orbital, or impact-body origins). Despite growing recognition that these events are changing in frequency and intensity, a universal model of ecological responses to these events is slow to emerge. Extreme events, negative and positive, contrast with normal events in terms of their effects on the physiology, ecology, and evolution of organisms, hence also on water, carbon, and nutrient cycles. They structure biogeographic ranges and biomes, almost surely more than mean values often used to define biogeography. They are challenging to study for obvious reasons of field-readiness but also because they are defined by sequences of driving variables such as temperature, not point events. As sequences, their statistics (return times, for example) are challenging to develop, as also from the involvement of multiple environmental variables. These statistics are not captured well by climate models. They are expected to change with climate and land-use change but our predictive capacity is currently limited. A number of tools for description and analysis of extreme events are available, if not widely applied to date. Extremes for organisms are defined by their fitness effects on those organisms, and are specific to genotypes, making them major agents of natural selection. There is evidence that effects of extreme events may be concentrated in an extended recovery phase. We review selected events covering ranges of time and magnitude, from Snowball Earth to leaf functional loss in weather events. A number of events, such as the 2003 European heat wave, evidence effects on water and carbon cycles over large regions. Rising CO2 is the recent extreme of note, for its climatic effects and consequences for growing seasons, transpiration, etc., but also directly in its action as a substrate of photosynthesis

Venous disease of the lower extremities is common but is often misunderstood. It seems that the focus is on the exciting world of arterial anatomy and pathology, while the topic of venous anatomy and pathology comes in second place. However, venous diseases such as chronic venous insufficiency, leg ulcers, and varicose veins affect much of the population and may lead to disability and death. Nurses are often required to answer complex questions from the patients and his or her family about the patient's disease. Patients depend on nurses to provide accurate information in terms they can understand. Therefore it is important to have an understanding of the normal venous system of the legs before one can understand the complexities of venous diseases and treatments. This presents an overview of normal venous anatomy and physiology.

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.

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.

Smoking is a major risk factor for the development of heart failure (HF). Yet, little is known about smoking\\'s effects on the health status of established HF patients. HF patients were recruited from outpatient clinics across North America. The Kansas City Cardiomyopathy Questionnaire (KCCQ) was used to assess disease-specific health status. Smoking behaviors were classified as never having smoked, prior smoker, and as having smoked within the past 30 days. Risk-adjusted multivariable regression was used to evaluate the association of smoking status with baseline and 1-year KCCQ overall summary scores. Smoking was not associated with baseline health status. However, a significant effect was observed on 1-year health status among outpatients with HF with current smokers reporting significantly lower KCCQ scores than never smokers or ex-smokers. These findings highlight an additional adverse consequence of smoking in HF patients not previously discussed.

Studying rare extreme forms of Alzheimer disease (AD) may prove to be a useful strategy in identifying new genes involved in monogenic determinism of AD. Amyloid precursor protein (APP), PSEN1, and PSEN2 mutations account for only 85% of autosomal dominant early-onset AD (ADEOAD) families. We hypothesised that rare copy number variants (CNVs) could be involved in ADEOAD families without mutations in known genes, as well as in rare sporadic young-onset AD cases. Using high-resolution array comparative genomic hybridisation, we assessed the presence of rare CNVs in 21 unrelated ADEOAD cases, having no alteration on known genes, and 12 sporadic AD cases, with an age of onset younger than 55 years. The analysis revealed the presence of 7 singleton CNVs (4 in ADEOAD and 3 in sporadic cases) absent in 1078 controls and 912 late-onset AD cases. Strikingly, 4 out of 7 rearrangements target genes (KLK6, SLC30A3, MEOX2, and FPR2) encoding proteins that are tightly related to amyloid-β peptide metabolism or signalling. Although these variants are individually rare and restricted to particular subgroups of patients, these findings support the causal role, in human pathology, of a set of genes coding for molecules suspected for a long time to modify Aβ metabolism or signalling, and for which animal or cellular models have already been developed.
Extreme cosmos

The universe is all about extremes. Space has a temperature 270°C below freezing. Stars die in catastrophic supernova explosions a billion times brighter than the Sun. A black hole can generate 10 million trillion volts of electricity. And hypergiants are stars 2 billion kilometres across, larger than the orbit of Jupiter. Extreme Cosmos provides a stunning new view of the way the Universe works, seen through the lens of extremes: the fastest, hottest, heaviest, brightest, oldest, densest and even the loudest.

The purpose of this study was to examine measures of chronic disease severity and treatment according to insurance status in a clinical trial setting. Baseline insurance status of 776 patients with type 2 diabetes and stable coronary artery disease (CAD) enrolled in the United States in the Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial was analyzed with regard to measures of metabolic and cardiovascular risk factor control. Compared with patients with private or public insurance, the uninsured were younger, more often female, and less often white non-Hispanic. Uninsured patients had the greatest burden of CAD. Patients with public insurance were treated with the greatest number of medications, had the greatest self-reported functional status, and the lowest mean glycosylated hemoglobin and low-density lipoprotein (LDL) cholesterol values. Overall, for 5 measured risk factor targets, the mean number above goal was 2.49 ± 1.18. After adjustment for demographic and clinical variables, insurance status was not associated with a difference in risk factor control. In the BARI 2D trial, we did not observe a difference in baseline cardiovascular risk factor control according to insurance status. An important observation, however, was that risk factor control overall was suboptimal, which highlights the difficulty in treating type 2 diabetes and CAD irrespective of insurance status.

To elucidate the association between antiplatelet use in patients with non-haemorrhagic moyamoya disease before hospital admission and good functional status on admission in Japan. Retrospective, multicentre, non-randomised, observational study. Nationwide registry data in Japan. A total of 1925 patients with non-haemorrhagic moyamoya disease admitted between 1 April 2012 and 31 March 2014 in Japan. We performed propensity score-matched analysis to examine the association between prehospital antiplatelet use and no significant disability on hospital admission, as defined by a modified Rankin Scale score of 0 or 1. Propensity-matched patients who received prehospital antiplatelet drugs were associated with a good outcome on hospital admission (OR adjusted for all covariates, 3.82; 95% CI 1.22 to 11.99) compared with those who did not receive antiplatelet drugs prior to hospital admission. Prehospital antiplatelet use was significantly associated with good functional status on hospital admission among patients with non-haemorrhagic moyamoya disease in Japan. Our results suggest that prehospital antiplatelet use should be considered when evaluating outcomes of patients with non-haemorrhagic moyamoya disease. Published by the BMJ Publishing Group Limited.

Full Text Available Upper extremity pain can originate from the musculoskeletal system, or be a reflection of problems originating from various organs. Therefore, it is highly important to perform a detailed clinical evaluation on patients during differential diagnosis. In this case report, we present a 61 year-old male patient who was admitted with pain in both upper extremities and the upper back that presumed to be of cardiac origin following our clinical evaluations. The patient was referred to the cardiology department, where he was diagnosed with coronary heart disease. The patient’s complaints of pain were fully resolved through the application of an intracoronary stent.

The potential need for an ostomy is a main concern for patients with inflammatory bowel disease. We performed this study to evaluate the impact of a long-term ostomy (≥6 mo duration) on the functional status and specific patient-reported outcomes in a population of patients with Crohn's disease (CD). We performed a cross-sectional analysis within the Crohn's and Colitis Foundation of America Partners cohort. Bivariate analyses and logistic regression models were used to investigate associations between ostomy and various demographic, disease factors, and patient-reported outcomes for health-related quality of life. A total of 402 CD patients with ostomy for a minimum duration of 6 months were compared with 4331 CD patients with no ostomy. Patients with ostomy were more likely to be in clinical remission compared with those without ostomy, 48.5% versus 31.3%, respectively. Having an ostomy did not impact the overall health-related quality of life and was not associated with anxiety, depression, sleep disturbances, or reduced sexual interest and satisfaction. However, the presence of ostomy was associated with reduced social role satisfaction in both patients with controlled and active disease. Additionally, in the subset of patients who did not achieve clinical remission, those with ostomy experienced greater pain interference (odds ratio, 1.63; 95% confidence interval, 1.12-2.35) and fatigue (odds ratio, 1.66; 95% confidence interval, 1.15-2.39). Ostomy is well tolerated in CD patients, particularly when clinical remission is achieved.
African horse sickness: The potential for an outbreak in disease-free regions and current disease control and elimination techniques.

African horse sickness (AHS) is an arboviral disease of equids transmitted by Culicoides biting midges. The virus is endemic in parts of sub-Saharan Africa and official AHS disease-free status can be obtained from the World Organization for Animal Health on fulfilment of a number of criteria. AHS is associated with case fatality rates of up to 95%, making an outbreak among naïve horses both a welfare and economic disaster. The worldwide distributions of similar vector-borne diseases (particularly bluetongue disease of ruminants) are changing rapidly, probably due to a combination of globalisation and climate change. There is extensive evidence that the requisite conditions for an AHS epizootic currently exist in disease-free countries. In particular, although the stringent regulations enforced upon competition horses make them extremely unlikely to redistribute the virus, there are great concerns over the effects of illegal equid movement. An outbreak of AHS in a disease free region would have catastrophic effects on equine welfare and industry, particularly for international events such as the Olympic Games. While many regions have contingency plans in place to manage an outbreak of AHS, further research is urgently required if the equine industry is to avoid or effectively contain an AHS epizootic in disease-free regions. This review describes the key aspects of AHS as a global issue and discusses the evidence supporting concerns that an epizootic may occur in AHS free countries, the planned government responses, and the roles and responsibilities of equine veterinarians. © 2016 EVJ Ltd.

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.

Trastuzumab, a monoclonal antibody against HER2, has become standard of care for metastatic HER2-overexpressing esophagogastric adenocarcinoma and is currently investigated as (neo)adjuvant treatment option in HER2-positive esophagogastric adenocarcinoma. The HER2 status is commonly determined on archived material of the primary tumor. However, this status may change over the course of treatment or disease progression. The aim of this study was to assess the dynamics of HER2 status in esophageal adenocarcinoma (EAC) in patients with resectable and recurrent disease, and to determine the associations of these changes with clinical outcome. Discordance, defined as any change in HER2 status between matched biopsy and post-neoadjuvant chemoradiation therapy resection specimen ( N = 170), or between matched resection specimen and recurrence of patients not eligible for curative treatment ( N = 61), was determined using the standardized HER2 status scoring system. Clinically relevant positive discordance was defined as a change to HER2 positive status, as this would imply eligibility for HER2-targeted therapy. A difference in HER2 status between biopsy and resection specimen and resection specimen and metachronous recurrence was observed in 2.1% ( n = 3) and 3.3% ( n = 2) of the paired cases, respectively. Clinically relevant discordance was detected in 1.4% ( n = 2) of the resectable patients and 1.6% ( n = 1) of the patients with recurrent disease. Patients with HER2-positive status tumors before start of neoadjuvant treatment showed better overall survival, but not statistically significant. No association between HER2 status discordance and survival was found. Clinically relevant HER2 status discordance was observed and in order to prevent under-treatment of patients, the assessment of HER2 status in the metastatic setting should preferably be performed on the most recently developed lesions if the previous HER2 assessment on archival material of the primary tumor

Huntington's disease (HD) is a monogenic neurodegenerative disorder caused by a CAG-repeat expansion in the Huntingtin gene. Presence of this expansion signifies certainty of disease onset, but only partly explains age at which onset occurs. Genome-wide association studies have shown that naturally occurring genetic variability influences HD pathogenesis and disease onset. Investigating the influence of biological traits in the normal population, such as variability in white matter properties, on HD pathogenesis could provide a complementary approach to understanding disease modification. We have previously shown that while white matter diffusivity patterns in the left sensorimotor network were similar in controls and HD gene-carriers, they were more extreme in the HD group. We hypothesized that the influence of natural variation in diffusivity on effects of HD pathogenesis on white matter is not limited to the sensorimotor network but extends to cognitive, limbic, and visual networks. Using tractography, we investigated 32 bilateral pathways within HD-related networks, including motor, cognitive, and limbic, and examined diffusivity metrics using principal components analysis. We identified three independent patterns of diffusivity common to controls and HD gene-carriers that predicted HD status. The first pattern involved almost all tracts, the second was limited to sensorimotor tracts, and the third encompassed cognitive network tracts. Each diffusivity pattern was associated with network specific performance. The consistency in diffusivity patterns across both groups coupled with their association with disease status and task performance indicates that naturally-occurring patterns of diffusivity can become accentuated in the presence of the HD gene mutation to influence clinical brain function. © 2018 The Authors Human Brain Mapping Published by Wiley Periodicals, Inc.

Full Text Available Aim: to identify the phenotypic characteristics of indeterminate connective tissue dysplasia, which help to predict the progression of varicose veins of lower extremities and disease recurrence after surgery. Material and Methods. The long-term results of surgical treatment of 60 patients with varicose veins of lower extremities in a 5-year period after phlebectomy were analyzed. The phenotypic characteristics of indeterminate connective tissue dysplasia were researched. 24 patients had recurrence of varicose veins of lower extremities associated with disease progression; 36 patients did not have recurrence of varicose veins of lower extremities. Results. All the patients demonstrated the signs of indeterminate connective tissue dysplasia, whereas their frequency was different. There were specified nine phenotypic characteristics of indeterminate connective tissue dysplasia, which were significantly more frequent for patients with recurrence of varicose vein disease of lower extremities: 1 postural abnormality, 2 flat foot, 3 skin pallor, 4 hyperextension of skin, 5 positive "wrist test", 6 positive "pollex test", 7 diastasis recti abdominis, 8 myopia, 9 hematomas which form quickly. Conclusion. The determined sum of phenotypic characters of indeterminate connective tissue dysplasia allows to predict progression of varicose vein disease of lower extremities, and offers new opportunities for improving the results of surgical treatment via developing special therapeutic measures aimed at improving lifestyle and dysplasia treatment.

Full Text Available Using World Statistics Data from the year 2012, health status differences between countries along the “New Silk Road” were compared and analyzed. Life expectancy at birth, life expectancy at age 60, healthy life expectancy, neonatal mortality rate, infant mortality rate, under-five mortality rate, maternal mortality ratio, as well as certain disease incidence rates were used. The study indicated that the 12 countries along the New Silk Road had longer life expectancy at birth. Females had longer life expectancy at birth than males, but life expectancy at age 60 was shorter than the global average, and healthy life expectancy at birth was also shorter. Maternal health status was generally good in each country. China, Russia, and 4 other countries had better children’s health status than India, Tajikistan, Pakistan, and Afghanistan. Non-communicable diseases caused higher mortality than communicable diseases and accidental injuries. However, the age standardized mortality rates of communicable diseases in India, Tajikistan, Pakistan, and Afghanistan were still relatively high. Communicable diseases were also the leading cause of reduction in life expectancy. Tuberculosis had a more significant impact on health status. In conclusion, health status varies among the New Silk Road countries. Countries including China and Iran have relatively better health status, and non communicable diseases were the predominant risk factor impacting health. However, in countries such as India and Afghanistan, mortality caused by communicable diseases is still prominent. Under the current trend of globalization, New Silk Road countries are supposed to collaborate to expand their healthcare systems, and improve the health conditions for their people.
Legacies from extreme drought increase ecosystem sensitivity to future extremes

Climate extremes, such as drought, are increasing in frequency and intensity, and the ecological consequences of these extreme events can be substantial and widespread. Although there is still much to be learned about how ecosystems will respond to an intensification of drought, even less is known about the factors that determine post-drought recovery of ecosystem function. Such knowledge is particularly important because post-drought recovery periods can be protracted depending on the extent to which key plant populations, community structure and biogeochemical processes are affected. These drought legacies may alter ecosystem function for many years post-drought and may impact future sensitivity to climate extremes. We experimentally imposed two extreme growing season droughts in a central US grassland to assess the impacts of repeated droughts on ecosystem resistance (response) and resilience (recovery). We found that this grassland was not resistant to the first extreme drought due to reduced productivity and differential sensitivity of the co-dominant C4 grass (Andropogon gerardii) and C3 forb (Solidago canadensis) species. This differential sensitivity led to a reordering of species abundances within the plant community. Yet, despite this large shift in plant community composition, which persisted post-drought, the grassland was highly resilient post-drought, due to increased abundance of the dominant C4 grass. Because of this shift to increased C4 grass dominance, we expected that previously-droughted grassland would be more resistant to a second extreme drought. However, contrary to these expectations, previously droughted grassland was more sensitive to drought than grassland that had not experienced drought. Thus, our result suggest that legacies of drought (shift in community composition) may increase ecosystem sensitivity to future extreme events.
Lactase persistence, NOD2 status and Mycobacterium avium subsp. paratuberculosis infection associations to Inflammatory Bowel Disease

2012-06-01

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

Interpreting magnesium status to enhance clinical care: key indicators.

To update advances in identifying factors affecting magnesium (Mg) status that assist in providing improved evidence-based clinical decision-making for assessing Mg status. Findings from recent cohort studies, small randomized control trials, and multiple meta-analyses reinforce earlier work that serum Mg concentrations, urinary Mg excretion, and Mg dietary intakes are inversely associated with cardiovascular disease, chronic kidney disease, and diabetes. These studies indicate that the reference range for serum Mg needs updating, and that individuals with serum Mg in the range of 0.75-0.85 mmol/l and displaying changes in other factors associated with a low Mg status may be Mg deficient. Individuals with serum Mg concentrations below this range most likely are Mg deficient and, above this range, are most likely Mg sufficient. The combined determination of serum Mg concentration, 24-h urinary Mg excretion, and dietary Mg intake is currently the most practical method to obtain a sound assessment of Mg status. The strong correlations of Mg deficiency with increased risk of several chronic diseases, some of which exist as comorbidities, indicate that Mg status should be ascertained in patients presenting such disorder.

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 < 0.0001). High CONUT scores showed a significant increase in the incidence of MACE compared with low CONUT scores, even after adjusting for confounding factors (hazard ratio: 1.64, 95% confidence interval 1.30-2.07, p < 0.0001). Adding CONUT scores to a baseline model with established risk factors improved the C-index (p = 0.02), net reclassification improvement (p = 0.004) and integrated discrimination improvement (p = 0.0003). 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.

To investigate the test-retest reliability of the 4-meter walk test (4 MWT) and 10-meter walk test (10 MWT) in patients undergoing lower extremity surgery during inpatient rehabilitation. In all, 102 patients with total hip arthroplasty (THA), total knee arthroplasty (TKA), lower extremity fracture (LEF) and soft tissue operation were recruited. Patients performed two 4 MWT and two 10 MWT trials on the same day. The same researcher performed all the measurements to avoid inter-rater variability. The 4 MWT and 10 MWT were shown to have excellent test-retest reliability. The ICCs for the 4 MWT and 10 MWT were found as 0.94 and 0.95, respectively. The SEMs for the 4 MWT and 10 MWT were 2.0 and 5.5 seconds, respectively. The smallest real difference at the 95% confidence level (SRD95) was 5.5 seconds for the 4 MWT and 12.2 seconds for 10 MWT and SRD95 percentage was 31.2 for the 4 MWT and 28.5 for the 10 MWT. Both the 4 MWT and the 10 MWT have excellent reliability in patients undergoing lower extremity surgery such as TKA, THA, LEF and soft tissue operation during inpatient rehabilitation. Clinicians and researchers can be confident that changes above the SRD95s for the different patient groups, for both sexes and with regard to weight-bearing status, represent a real clinical change in rehabilitation process. Implications for Rehabilitation The 4 MWT and the 10 MWT are simple methods and were also shown to be reliable measurement methods in many patient groups. This study illustrates that the test-retest reliability of the 4 MWT and 10 MWT are excellent in patients undergoing lower extremity surgery during inpatient rehabilitation (ICC: 0.94 for 4 MWT, ICC: 0.95 for 10 MWT). Clinicians and researchers can be confident that changes above the SRD95s for the different patient groups, for both sexes and with regard to weight-bearing status represent a real clinical change in rehabilitation process.

Convulsive status epilepticus is the most extreme form of seizure. It is a medical and neurological emergency that requires prompt and appropriate treatment. Treatment of convulsive status epilepticus is usually divided into stages/steps. The International League Against Epilepsy has released a new definition of status epilepticus that may help to unify the definition in future studies. Over the last few years new information has become available regarding its management. The Rapid Anticonvulsant Medication Prior to Arrival Trial demonstrated non-inferiority of intramuscular midazolam in early status epilepticus compared with intravenous lorazepam. Valproate and levetiracetam have also emerged as possible alternatives to phenytoin in established status epilepticus. The potential role of lacosamide in this stage of status epilepticus remains to be defined. The ongoing Established Status Epilepticus Treatment Trial may help to determine the most effective treatment for benzodiazepine-resistant status epilepticus. Management of refractory status epilepticus and super-refractory status epilepticus remains mostly non-evidence-based. Increasing recognition of a possible autoimmune aetiology has led to the use of immune-modulation in super-refractory status epilepticus. Ketamine is also increasingly used in this challenging condition. There are also reports of potential use of a ketogenic diet and magnesium.

Wonokromo, Dadapan and Juanda estuaries are extreme waters located around Surabaya environment. This is because of a lot of organic material intake, which provided nutrients for plankton growth. In addition, the waters is also dynamic in reason of physico-chemical, geological and biological processes controlled by the tides and freshwater run-off from the river that empties into it. The objective of this study was to identify the presentation of plankton in extreme waters based on brightness and ammonia level. The study was conducted in January 2017. Three sampling locations were Wonokromo, Dadapan and Juanda estuaries. Each station consists of three points based on distances, which were 400, 700, and 1000 meters from the coastline. The brightness in Wonokromo, Dadapan, and Juanda environment was 60, 40, and 100 cm, respectively. The result of ammonia in Wonokromo, Dadapan, and Juanda estuary was 0.837, 0.626, and 0.396 mg/L, correspondingly. Nine classes of phytoplankton’s were found in three locations (bacillariophyceae, dynophyceae, chlorophyceae, cyanophyceae, crysophyceae, euglenoidea, trebouxlophyceae, mediophyceae, and nitachiaceae) and five classes of zooplanktons (maxillopoda, hexanuplia, copepoda, malacostraca, and oligotrichea). The density of plankton in Wonokromo, Dadapan and Juanda environments, was 37.64, 63.80, and 352.85 cells/L, respectively.

The aim of this study was to evaluate the age-appropriate immunization coverage in 366 children with chronic neurological disease (CND), to evaluate the use of vaccines not included in routine program, to evaluate serological tests for vaccine-preventable diseases and to describe the related factors in unvaccinated children. 95.6% of all children with had received age-appropriate vaccinations according to the actual National Immunization Program (NIP) during childhood. 12 children (3.6%) had not received vaccines; only two had true contraindications. Because most of the vaccines have been implemented through the NIP for 10 years in Turkey, 88% of children required these new vaccines or booster doses. Moreover, 86.6% of the children and 92.6% of household contacts had no prior history of influenza vaccine. Furthermore, 88% of the patients had not received the varicella vaccine, and the anti-varicella IgG levels were only negative in 27.9%. In addition, 18.6% of the children were negative for anti-mumps IgG, 23.7% for anti-measles IgG, and 6.3% for anti-rubella IgG. Anti-HBs IgG level was 0-10 IU/L in 45.6% of the patients (most of them previously vaccinated) and 79.8% were negative for hepatitis A IgG antibodies. For pertussis infection, the antibody titers of 54.1% of patients were below the protective level, and 10% of patients had a prior acute pertussis infection. Therefore, it is suggested that children with CND should be evaluated for their vaccination status during their first and follow-up visits at certain intervals, and their primary immunization should be completed; moreover, many will need revaccination or booster doses.

To assess the nutritional status via the SGA (subjective global assessment) screening tool of patients at all stages of hepatitis C virus (HCV) liver disease. Study Design: Descriptive study. Place and Duration of Study: Out-patient Clinics of the Aga Khan University Hospital, Karachi, conducted from October 2009 to January 2011. Methodology: Patients with hepatitis C virus infection and their HCV-negative attendants were enrolled from the outpatient clinics, and categorized into 4 groups of 100 patients each: healthy controls (HC), those with chronic hepatitis C infection (CHC), compensated cirrhotics (CC) and decompensated cirrhotics (DC). The validated subjective global assessment (SGA) tool was used to assess nutritional status. Results: A total of 400 patients were enrolled. Most of the patients in the HC group were class 'A' (best nutritional status). In contrast, the majority (64%) in the DC group were in the class 'C' (worst status). The compensated cirrhosis (CC) group showed that 90% of patients were malnourished, while 98% of all patients were malnourished in the DC group, predominantly class 'C'. Most importantly, 14% of patients with chronic hepatitis C (CHC) also scored a 'B' on the SGA; which when compared to HC was statistically significant (p=0.005). As the groups progressed in their disease from CHC to DC, the transition in nutritional status from 'A' to 'C' between groups was statistically significant. Conclusion: Malnutrition occurs early in the course of HCV, and progresses relentlessly throughout the spectrum of HCV disease. (author)

Full Text Available Severe environmental conditions affect organisms in two major ways. The environment may be predictably severe such as in deserts, polar and alpine regions, or individuals may be exposed to temporarily extreme conditions through weather, presence of predators, lack of food, social status etc. Existence in an extreme environment may be possible, but then to breed or molt in addition can present major bottlenecks that have resulted in the evolution of hormone-behavior adaptations to cope with unpredictable events. Examples of hormone-behavior adaptations in extreme conditions include attenuated testosterone secretion because territoriality and excess courtship may be too costly when there is one opportunity to reproduce. The individual may even become insensitive to testosterone when target areas of the brain regulating reproductive behavior no longer respond to the hormone. A second example is reduced sensitivity to glucocorticoids following acute stress during the breeding season or molt that allows successful reproduction and/or a vital renewal of the integument to endure extreme conditions during the rest of the year. Reduced sensitivity could involve: (a modulated response of the hypothalamo-pituitary-adrenal axis, (b reduced sensitivity to high glucocorticoid levels, or (c a combination of (a and (b. Moreover, corticosteroid binding proteins (CBP buffer responses to stress by reducing the movement of glucocorticoids into target cells. Finally, intracellular enzymes (11b-hydroxysteroid dehydrogenase and variants can deactivate glucocorticoids entering cells thus reducing interaction with receptors. These mechanisms have important implications for climate change and increasing extremes of weather [Current Zoology 57 (3: 363–374, 2011].

Background Approximately 1.5 million Americans are affected by Parkinson's disease [1] which includes the symptoms of postural instability and gait dysfunction. Currently, clinical evaluations of postural instability and gait dysfunction consist of a subjective rater assessment of gait patterns using items from the Unified Parkinson's Disease Rating Scale, and assessments can be insensitive to the effectiveness of medical interventions. Current research suggests the importance of cycling for Parkinson's disease patients, and while Parkinson's gait has been evaluated in previous studies, little is known about lower extremity control during cycling. The purpose of this study is to examine the lower extremity coordination patterns of Parkinson's patients during cycling. Methods Twenty five participants, ages 44-72, with a clinical diagnosis of idiopathic Parkinson's disease participated in an exercise test on a cycle ergometer that was equipped with pedal force measurements. Crank torque, crank angle and power produced by right and left leg were measured throughout the test to calculate Symmetry Index at three stages of exercise (20 Watt, 60 Watt, maximum performance). Findings Decreases in Symmetry Index were observed for average power output in Parkinson's patients as workload increased. Maximum power Symmetry Index showed a significant difference in symmetry between performance at both the 20 Watt and 60 Watt stage and the maximal resistance stage. Minimum power Symmetry Index did not show significant differences across the stages of the test. While lower extremity asymmetries were present in Parkinson's patients during pedaling, these asymmetries did not correlate to postural instability and gait dysfunction Unified Parkinson's Disease Rating Scale scores. Interpretation This pedaling analysis allows for a more sensitive measure of lower extremity function than the Unified Parkinson's Disease Rating Scale and may help to provide unique insight into current and

The distributions for human disease-specific mortality exhibit two striking characteristics: survivorship curves that intersect near the longevity limit; and, the clustering of best-fitting Weibull shape parameter values into groups centered on integers. Correspondingly, we have hypothesized that the distribution intersections result from either competitive processes or population partitioning and the integral clustering in the shape parameter results from the occurrence of a small number of rare, rate-limiting events in disease progression. In this report we initiate a theoretical examination of these questions by exploring serial chain model dynamics and parameteric competing risks theory. The links in our chain models are composed of more than one bond, where the number of bonds in a link are denoted the link size and are the number of events necessary to break the link and, hence, the chain. We explored chains with all links of the same size or with segments of the chain composed of different size links (competition). Simulations showed that chain breakage dynamics depended on the weakest-link principle and followed kinetics of extreme-values which were very similar to human mortality kinetics. In particular, failure distributions for simple chains were Weibull-type extreme-value distributions with shape parameter values that were identifiable with the integral link size in the limit of infinite chain length. Furthermore, for chains composed of several segments of differing link size, the survival distributions for the various segments converged at a point in the S(t) tails indistinguishable from human data. This was also predicted by parameteric competing risks theory using Weibull underlying distributions. In both the competitive chain simulations and the parametric competing risks theory, however, the shape values for the intersecting distributions deviated from the integer values typical of human data. We conclude that rare events can be the source of

Periodontal disease has been shown to be associated with cardiovascular disease (CVD). No known studies evaluate the relationship between periodontal disease status and biomarkers of CVD risk in the American Indian/Alaskan Native (AI/AN) population despite their disproportionately high rates of poor oral health and cardiovascular disease-related outcomes. This study compared levels of interleukin (IL)-6 and C-reactive protein (CRP) across increasing severity of periodontal disease status among younger adults between the ages of 21 and 43 years. Plasma levels of IL-6 and CRP were measured in adult participants (ages 21 to 43 years) as part of a study of periodontal disease and CVD risk among an AI/AN population in southern California (n = 59). Periodontal evaluations were performed and disease status was classified into three categories based on highest probing depth (none/mild: disease or active infection were excluded. Severe periodontitis was significantly associated with increased levels of IL-6 compared with those with none or mild periodontitis before controlling for other variables (P = 0.02), but lacked significance after controlling for sex, BMI, smoking status, and high-density lipoprotein (P = 0.09). Moderate periodontal disease was positively associated with IL-6 levels after controlling for potential confounders (P = 0.01). Periodontal status was not associated with CRP, before or after adjusting for covariates. In this otherwise healthy AI/AN adult sample, moderate periodontal disease compared with none or mild periodontal disease was associated with increased levels of IL-6. High levels of CRP found in this population warrant further research. © 2018 American Academy of Periodontology.

Little is known about the prognostic significance of specific characteristics of magnetic resonance imaging (MRI) measured plaque in the superficial femoral artery (SFA). Associations of MRI-measured plaque quantity, lumen area, and plaque composition in the SFA with subsequent mobility loss were studied in people with lower extremity peripheral artery disease (PAD). Participants with an ankle-brachial index (ABI) Mobility loss was defined as becoming unable to walk up and down a flight of stairs or walk one-quarter of a mile without assistance among participants without mobility impairment at baseline. Analyses adjusted for age, sex, race, comorbidities, ABI, physical activity, and other confounders. Of 308 PAD participants without baseline mobility impairment, 100 (32.5%) developed mobility loss during follow-up. Compared to the lowest mean plaque area tertile at baseline, participants in the highest (worst) plaque area tertile had a higher rate of mobility loss (hazard ratio (HR) = 2.08, 95% confidence interval (CI) = 1.14-3.79, p = 0.018). Compared to the highest mean lumen area tertile, the smallest (worst) mean lumen area tertile was associated with greater mobility loss (HR = 2.18, 95% CI = 1.20-3.96, p = 0.011). Neither lipid rich necrotic core nor calcium in the SFA were associated with mobility loss. In conclusion, greater plaque quantity and smaller lumen area in the proximal SFA, but not lipid rich necrotic core or calcium, were associated with higher mobility loss in people with PAD.

Non-communicable diseases are the leading global cause of death and disproportionately afflict those living in low-income and lower-middle-income countries (LLMICs). The association between socioeconomic status and non-communicable disease behavioural risk factors is well established in high-income countries, but it is not clear how behavioural risk factors are distributed within LLMICs. We aimed to systematically review evidence on the association between socioeconomic status and harmful use of alcohol, tobacco use, unhealthy diets, and physical inactivity within LLMICs. We searched 13 electronic databases, including Embase and MEDLINE, grey literature, and reference lists for primary research published between Jan 1, 1990, and June 30, 2015. We included studies from LLMICs presenting data on multiple measures of socioeconomic status and tobacco use, alcohol use, diet, and physical activity. No age or language restrictions were applied. We excluded studies that did not allow comparison between more or less advantaged groups. We used a piloted version of the Cochrane Effective Practice and Organisation of Care Group data collection checklist to extract relevant data at the household and individual level from the included full text studies including study type, methods, outcomes, and results. Due to high heterogeneity, we used a narrative approach for data synthesis. We used descriptive statistics to assess whether the prevalence of each risk factor varied significantly between members of different socioeconomic groups. The study protocol is registered with PROSPERO, number CRD42015026604. After reviewing 4242 records, 75 studies met our inclusion criteria, representing 2 135 314 individuals older than 10 years from 39 LLMICs. Low socioeconomic groups were found to have a significantly higher prevalence of tobacco and alcohol use than did high socioeconomic groups. These groups also consumed less fruit, vegetables, fish, and fibre than those of high

To evaluate protein intake, nitrogen balance and nutritional status of clinically stable patients with Parkinson's disease (PD). A cross-sectional study of PD patients Hoehn-Yahr scale stage 1-3 and subjects with no neurologic disease (controls) matched for age and gender. All participants underwent a diet history interview, anthropometric measurements, bioelectrical impedance and food record over three non-consecutive days, including a weekend. A 24-hour urine collection and fasting venous blood sampling were collected from the participants for evaluation of creatinine clearance, creatinine height index and the nitrogen balance. The mean age of PD patients was 58.9 ± 12.8 year compared to 54.7 ± 12.6 year of the controls, P = 0.34. One third of PD group had symptoms of dysphagia and ingested less water and fibers when compared to controls. Calf circumference was small in PD group (35.5 ± 2.8 vs. 38.4 ± 3.5 cm, P = 0.012). Intake of nitrogen was significantly lower and nitrogen balance was negative in PD patients (-1.8 ± 3.9 vs. 1.1 ± 4.2 controls, P = 0.06). The antioxidants folate and vitamin E were consumed in small amounts in both groups, although significantly less in PD patients (P = 0.04 and 0.03, respectively). Daily intakes of protein of approximately 1.1 g/kg by clinically stable PD patients may not be enough to ensure a neutral calorie-nitrogen balance and muscle tissue conservation. Larger studies are necessary to provide a more comprehensive picture of PD patients' metabolic status. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

Purpose: More than 70% of Ewing tumors occur in the extremities and pelvis. This study identified factors influencing local control and functional outcomes after management with definitive radiotherapy (RT). Patients and Methods: A total of 75 patients with a localized Ewing tumor of the extremity or pelvis were treated with definitive RT at the University of Florida between 1970 and 2006 (lower extremity tumors in 30, pelvic tumors in 26, and upper extremity tumors in 19). RT was performed on a once-daily (40%) or twice-daily (60%) basis. The median dose was 55.2 Gy in 1.8-Gy daily fractions or 55.0 Gy in 1.2-Gy twice-daily fractions. The median observed follow-up was 4.7 years. Functional outcome was assessed using the Toronto Extremity Salvage Score. Results: The 10-year actuarial overall survival, cause-specific survival, freedom from relapse, and local control rate was 48%, 48%, 42%, and 71%, respectively. Of the 72 patients, 3 required salvage amputation. Inferior cause-specific survival was associated with larger tumors (81% for tumors 3 . Conclusions: Limb preservation was effectively achieved through definitive RT. Treating limited field sizes with hyperfractionated high-energy RT could minimize long-term complications and provides superior functional outcomes

Purpose: To perform a joint analysis of data from 3 contributing centers within the intraoperative electron-beam radiation therapy (IOERT)-Spanish program, to determine the potential of IOERT as an anticipated boost before external beam radiation therapy in the multidisciplinary treatment of pediatric extremity soft-tissue sarcomas. Methods and Materials: From June 1993 to May 2013, 62 patients (aged <21 years) with a histologic diagnosis of primary extremity soft-tissue sarcoma with absence of distant metastases, undergoing limb-sparing grossly resected surgery, external beam radiation therapy (median dose 40 Gy) and IOERT (median dose 10 Gy) were considered eligible for this analysis. Results: After a median follow-up of 66 months (range, 4-235 months), 10-year local control, disease-free survival, and overall survival was 85%, 76%, and 81%, respectively. In multivariate analysis after adjustment for other covariates, tumor size >5 cm (P=.04) and R1 margin status (P=.04) remained significantly associated with local relapse. In regard to overall survival only margin status (P=.04) retained association on multivariate analysis. Ten patients (16%) reported severe chronic toxicity events (all grade 3). Conclusions: An anticipated IOERT boost allowed for external beam radiation therapy dose reduction, with high local control and acceptably low toxicity rates. The combined radiosurgical approach needs to be tested in a prospective trial to confirm these results.

Full Text Available Autoimmune thyroid disease associated with interferon therapy can manifest as destructive thyroiditis, Graves’ Hyperthyroidism, and autoimmune (often subclinical hypothyroidism, the latter persisting in many patients. There are scare reports of a single patient developing extremes of autoimmune thyroid disease activated by the immunomodulatory effects of interferon. A 60-year-old man received 48 weeks of pegylated interferon and ribavirin therapy for chronic HCV. Six months into treatment, he reported fatigue, weight gain, and slowed cognition. Serum thyroid stimulating hormone (TSH was 58.8 mIU/L [0.27–4.2], fT4 11.1 pmol/L [12–25], and fT3 4.2 pmol/L [2.5–6.0] with elevated anti-TPO (983 IU/mL [<35] and anti-TG (733 U/mL [<80] antibodies. He commenced thyroxine with initial clinical and biochemical resolution but developed symptoms of hyperthyroidism with weight loss and tremor 14 months later. Serum TSH was <0.02 mIU/L, fT4 54.3 pmol/L, and fT3 20.2 pmol/L, with an elevated TSH receptor (TRAb, 4.0 U/L [<1.0], anti-TPO (1,163 IU/mL and anti-TG (114 U/mL antibodies. Technetium scan confirmed Graves’ Disease with bilateral diffuse increased tracer uptake (5.9% [0.5–3.5%]. The patient commenced carbimazole therapy for 6 months. Treatment was ceased following spontaneous clinical and biochemical remission (TSH 3.84 mIU/L, fT4 17pmol/L, fT3 4.5 pmol/L, and TRAb <1 U/L. This raises the need to monitor thyroid function closely in patients both during and following completion of interferon treatment.
Global patterns of NDVI-indicated vegetation extremes and their sensitivity to climate extremes

Extremes in climate have significant impacts on ecosystems and are expected to increase under future climate change. Extremes in vegetation could capture such impacts and indicate the vulnerability of ecosystems, but currently have not received a global long-term assessment. In this study, a robust method has been developed to detect significant extremes (low values) in biweekly time series of global normalized difference vegetation index (NDVI) from 1982 to 2006 and thus to acquire a global pattern of vegetation extreme frequency. This pattern coincides with vegetation vulnerability patterns suggested by earlier studies using different methods over different time spans, indicating a consistent mechanism of regulation. Vegetation extremes were found to aggregate in Amazonia and in the semi-arid and semi-humid regions in low and middle latitudes, while they seldom occurred in high latitudes. Among the environmental variables studied, extreme low precipitation has the highest slope against extreme vegetation. For the eight biomes analyzed, these slopes are highest in temperate broadleaf forest and temperate grassland, suggesting a higher sensitivity in these environments. The results presented here contradict the hypothesis that vegetation in water-limited semi-arid and semi-humid regions might be adapted to drought and suggest that vegetation in these regions (especially temperate broadleaf forest and temperate grassland) is highly prone to vegetation extreme events under more severe precipitation extremes. It is also suggested here that more attention be paid to precipitation-induced vegetation changes than to temperature-induced events. (letter)

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.

The purpose of this study was to examine the effect of upper and lower body extremity strengthening exercise in patients with Fibromyalgia (FM) within an existing multidisciplinary treatment program. Patients between the ages of 18-65 with the medical diagnosis of FM. Comparative study design. The control and experimental group received the same multidisciplinary treatment except that the experimental group performed upper and lower extremity strengthening exercises. The Fibromyalgia Impact Questionnaire (FIQ) was administered at evaluation and discharge from the program in order to measure change in quality of life (QOL). Statistically significant changes in FIQ scores were found for both groups. The addition of extremity strengthening in the experimental group produced an average 4 points greater reduction in FIQ score, however, these results are not considered statistically significant. This study appears to validate the success of a multidisciplinary approach in treating patients with FM, with the possibility for further benefit with the addition of extremity strengthening.

Taguchi, Yoshiharu; Takashima, Shutaro; Tanaka, Kortaro

2013-01-01

Radiation-induced carotid artery disease (RCAD) often develops in patients who have received neck radiotherapy for the treatment of various malignant tumors. However, the doctors who ordered or performed neck radiotherapy seem to pay little attention to RCAD which may subsequently occur, and the present status of the awareness in these doctors for RCAD is unclear in Japan. Therefore, we conducted a questionnaire survey of the present status of these doctors' awareness for RCAD. A questionnaire form regarding the recognition of RCAD was sent to 368 departments of otolaryngology, oral surgery, or radiology of university hospitals in Japan. Responses to the questionnaire were received from 213 of the 368 departments of otolaryngology, oral surgery or radiology of university hospitals (response collection rate: 57.9%). One hundred and sixty-one departments (75.9%) were aware of the existence of RCAD, but only 20 departments (9.4%) conducted regular examinations for RCAD after neck radiotherapy such as ultrasound neck echography and MR angiography. Only 6.3% departments took preventive measures for RCAD such as reduction in radiation dose or administration of antiplatelets. The present survey revealed that many patients who had undergone neck radiotherapy for the treatment of malignancy did not receive proper medical attention for RCAD in Japan. Healthcare providers should be given adequate education about RCAD including its risk factors, possible preventive measures, diagnostic modalities, and treatment. Furthermore, a systematic clinical network should be established in which stroke specialists conduct proper examinations for early diagnosis of RCAD. (author)

In a prospective follow-up study of 158 consecutive patients 18 to 64 years old with unilateral lower extremity fracture, our aim was to disclose the impairment and disability 6 months after the injury. The patients were interviewed within 1 week after the trauma, and all patients returned...... the functional status before the injury. Additionally, three major aspects of impairments were measured 6 months after the fractures: range of motion, muscle strength, and pain. Most patients had a significantly higher SIP score 6 months after the fracture(s) than pretraumatically. The mean overall SIP score...... was 2.7 pretraumatically and 8.7 6 months posttraumatically. Major deficits in range of motion was observed, especially in the ankle joint. Additionally, loss of muscle strength was observed in the thigh and calf muscles in one fourth of the patients. Only low levels of residual pain were reported after...
[The disease and treatment of the frontline soldiers in Han dynasty].

Min, Hookie

2015-04-01

This paper purports to identify and analyze the medical information of the frontline soldiers in the Northwest borderland provinces of Han Dynasty, especially Juyan and Dunhuang region, through an heuristic reading of the Juyan Bamboo Slips and the Dunhuang Bamboo Slips of the Han Dynasty. My findings are as follows. The most frequent disease found in the bamboo slips was the external injury. The injury of the frontline soldiers mainly occurred from the quarrels among armed soldiers using weapons. The bamboo slips also demonstrate that the quarrels usually arose due to the fierce tension caused by the frontier line service such as heavy guard activity and labour duty. Undernourishment and chronic stress the soldiers suffered might be another reasons. The second most common disease harassing the soldiers was exogenous febrile disease. In most cases reviewed in this paper, the exogenous febrile disease was usually concurrent with complex symptoms such as chills, fever, headache, etc. The bamboo slips show that the exogenous febrile disease was related to the harsh climate of the Northwest provinces, featuring extremely dry weather and the large magnitude of diurnal temperature fluctuations. In addition, the annual temperature range in the Northwest province was huge, fluctuating between very cold and dry winter and very hot and dry summer. The third most common disease this study identified was the disorder of the digestive system and respiratory system. However, these two types of disease were virtually indistinguishable in the bamboo slips, because the ancient Chinese chroniclers did not distinguish them, usually dubbing both diseases simply 'abdominal pain.' It should be mentioned that a few slips mention contagious disease such as dysentery and dermatolosis, and sudden death, as well. Overall, the bamboo slips demonstrate extremely poor status of the soldiers' heath condition and poor medical environment surrounding the soldiers stationing in the Northwest

Abstract The National Health Insurance Service–Health Examinee Cohort during 2002 to 2013 was used to investigate the associations between periodontal disease (PD) and the following non-communicable diseases (NCDs): hypertension, diabetes mellitus, osteoporosis, cerebral infarction, angina pectoris, myocardial infarction, and obesity. Univariate and multivariate logistic regression analyses adjusting for potential confounders during the follow-up period—including age, sex, household income, insurance status, residence area, health status, and comorbidities—were used to estimated odds ratios (ORs) with 95% confidence intervals (CIs) in order to assess the associations between PD and NCDs. We enrolled 200,026 patients with PD and 154,824 subjects with a healthy oral status. Statistically, significant associations were found between PD and the investigated NCDs except for cerebral and myocardial infarction after adjusting for sociodemographic and comorbidity factors (P periodontitis pathogenesis as a triggering and mediating mechanism.

The aim was to culturally translate and validate the Persian lower extremity functional scale (LEFS) in a heterogeneous sample of outpatients with lower extremity musculoskeletal disorders (n = 304). This is a prospective methodological study. After a standard forward-backward translation, psychometric properties were assessed in terms of test-retest reliability, internal consistency, construct validity, dimensionality, and ceiling or floor effects. The acceptable level of intraclass correlation coefficient >0.70 and Cronbach's alpha coefficient >0.70 was obtained for the Persian LEFS. Correlations between Persian LEFS and Short-Form 36 Health Survey (SF-36) subscales of Physical Health component (rs range = 0.38-0.78) were higher than correlations between Persian LEFS and SF-36 subscales of Mental Health component (rs range = 0.15-0.39). A corrected item--total correlation of >0.40 (Spearman's rho) was obtained for all items of the Persian LEFS. Horn's parallel analysis detected a total of two factors. No ceiling or floor effects were detected for the Persian LEFS. The Persian version of the LEFS is a reliable and valid instrument that can be used to measure functional status in Persian-speaking patients with different musculoskeletal disorders of the lower extremity. Implications for Rehabilitation The Persian lower extremity functional scale (LEFS) is a reliable, internally consistent and valid instrument, with no ceiling or floor effects, to determine functional status of heterogeneous patients with musculoskeletal disorders of the lower extremity. The Persian version of the LEFS can be used in clinical and research settings to measure function in Iranian patients with different musculoskeletal disorders of the lower extremity.

Although upper-extremity disability has been shown to correlate highly with various psychosocial aspects of illness (e.g., self-efficacy, depression, kinesiophobia, and pain catastrophizing), the role of language in musculoskeletal health status is less certain. In an English-speaking outpatient hand surgery office setting, we sought to determine (1) whether a patient's primary native language (English or Spanish) is an independent predictor of upper-extremity disability and (2) whether there are any differences in the contribution of measures of psychological distress to disability between native English- and Spanish-speaking patients. A total of 122 patients (61 native English speakers and 61 Spanish speakers) presenting to an orthopaedic hand clinic completed sociodemographic information and three Patient-Reported Outcomes Measurement Information System (PROMIS)-based computerized adaptive testing questionnaires: PROMIS Pain Interference, PROMIS Depression, and PROMIS Upper-Extremity Physical Function. Bivariate and multivariable linear regression modeling were performed. Spanish-speaking patients reported greater upper-extremity disability, pain interference, and symptoms of depression than English-speaking patients. After adjusting for sociodemographic covariates and measures of psychological distress using multivariable regression modeling, the patient's primary language was not retained as an independent predictor of disability. PROMIS Depression showed a medium correlation (r = -0.35; p Spanish-speaking patients. PROMIS Pain Interference had a large correlation with disability in both patient cohorts (Spanish-speaking: r = -0.66; p immigration to the USA did not correlate with disability among Spanish speakers. Primary language has less influence on symptom intensity and magnitude of disability than psychological distress and ineffective coping strategies. Interventions to optimize mood and to reduce pain interference should be considered in
Diagnosis of Alzheimer’s Disease Based on Structural MRI Images Using a Regularized Extreme Learning Machine and PCA Features

Full Text Available Alzheimer’s disease (AD is a progressive, neurodegenerative brain disorder that attacks neurotransmitters, brain cells, and nerves, affecting brain functions, memory, and behaviors and then finally causing dementia on elderly people. Despite its significance, there is currently no cure for it. However, there are medicines available on prescription that can help delay the progress of the condition. Thus, early diagnosis of AD is essential for patient care and relevant researches. Major challenges in proper diagnosis of AD using existing classification schemes are the availability of a smaller number of training samples and the larger number of possible feature representations. In this paper, we present and compare AD diagnosis approaches using structural magnetic resonance (sMR images to discriminate AD, mild cognitive impairment (MCI, and healthy control (HC subjects using a support vector machine (SVM, an import vector machine (IVM, and a regularized extreme learning machine (RELM. The greedy score-based feature selection technique is employed to select important feature vectors. In addition, a kernel-based discriminative approach is adopted to deal with complex data distributions. We compare the performance of these classifiers for volumetric sMR image data from Alzheimer’s disease neuroimaging initiative (ADNI datasets. Experiments on the ADNI datasets showed that RELM with the feature selection approach can significantly improve classification accuracy of AD from MCI and HC subjects.

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

Preterm delivery is associated with high mortality and morbility perinatal, being the costs dispended by the family and the National Health System with preterm newborns extremely high. However, it has been difficult to reduce its incidence due to the various factors involved. There is scientific evidence which support the relationship between periodontal disease and preterm delivery. There is also evidence of tobacco as a risk factor for periodontal disease, even though the relationship with preterm delivery is not yet clear. The aims of our study were to evaluate, in women in a post-partum period, dental and periodontal status as well as the exposure to tobacco and to establish the relationship between these two factors with preterm delivery. We performed a case control study with 237 parturient women from the Department of Obstetrics and Gynecology of Hospital S. João, E.P.E., during the first 48 hours after birth. A total of 86 gave birth at a gestational age under 37 weeks (case group ) and 151 gave birth to term newborns with birthweight equal or superior 2500 g (control group). The prevalence of some indicators of periodontal disease in the studied population was extremely high, namely gingival inflammation and gingival recession, and more of 30% had values of probing depth equal or higher than 4 mm significantly. Based on these periodontal indicators, only the presence of recession in more than two teeth seems to increase the risk of preterm delivery in fivefold (OR = 5,28; IC95%: 1,63-17,04). There is a statistically significant association between probing depth equal or higher than 4mm and smoking during pregnancy. This association might be relevant because 20% of preterm newborns mothers smoked during pregnancy and the proportion that stopped smoking during pregnancy in this group of mothers was almost half of the number of the control group. Therefore it is necessary to embody the information about this thematic in the health education, not only in

The Water Framework Directive (WFD) regulates surface water quality standards in the European Union (EU). The Directive call for the identification and management of point and diffuse sources of pollution and requires the establishment of a 'programme of measures' for identified river basin districts, in order to achieve a "good status" by 2015. The hygienic quality of water is normally monitored using faecal indicator organisms (FIO), such as Escherichia coli, which indicate a potential risk to public health from human waterborne pathogens. Environmental factors influence the transmission of these pathogens and indicator organisms, and statistically significant relationships have been found between rainfall and outbreaks of waterborne disease. Climate change has been predicted to lead to an increase in severe weather events in many parts of Europe, including an increase in the frequency of extreme rainfall events. This in turn is likely to lead to an increase in incidents of human waterborne disease in Europe, unless measures are taken to predict and mitigate for such events. This study investigates a variety of environmental factors that influence the concentration of FIO in surface waters receiving faecal contamination from a variety of sources. Levels of FIO, including Escherichia coli, intestinal enterococci, somatic coliphage and GB124 (a human-specific microbial source tracking marker), were monitored in the Sussex Ouse catchment in Southeast England over a period of 26 months. These data were combined with geoinformatic environmental data within a GIS to map faecal contamination within the river. Previously, precipitation and soil erosion have been identified as major factors that can influence the concentration of these faecal markers, and studies have shown that slope, soil type and vegetation influence both the mechanisms and the rate by which erosion occurs in river catchments. Of the environmental variables studied, extreme precipitation was found to
Socio-economic status and overall and cause-specific mortality in Sweden

Full Text Available Abstract Background Previous studies have reported discrepancies in cause-specific mortality among groups of individuals with different socio-economic status. However, most of the studies were limited by the specificity of the investigated populations and the broad definitions of the causes of death. The aim of the present population-based study was to explore the dependence of disease specific mortalities on the socio-economic status in Sweden, a country with universal health care. Another aim was to investigate possible gender differences. Methods Using the 2006 update of the Swedish Family-Cancer Database, we identified over 2 million individuals with socio-economic data recorded in the 1960 national census. The association between mortality and socio-economic status was investigated by Cox's proportional hazards models taking into account the age, time period and residential area in both men and women, and additionally parity and age at first birth in women. Results We observed significant associations between socio-economic status and mortality due to cardiovascular diseases, respiratory diseases, to cancer and to endocrine, nutritional and metabolic diseases. The influence of socio-economic status on female breast cancer was markedly specific: women with a higher socio-economic status showed increased mortality due to breast cancer. Conclusion Even in Sweden, a country where health care is universally provided, higher socio-economic status is associated with decreased overall and cause-specific mortalities. Comparison of mortality among female and male socio-economic groups may provide valuable insights into the underlying causes of socio-economic inequalities in length of life.
Extreme meteorological conditions

Different meteorological variables which may reach significant extreme values, such as the windspeed and, in particular, its occurrence through tornadoes and hurricanes that necesarily incide and wich must be taken into account at the time of nuclear power plants' installation, are analyzed. For this kind of study, it is necessary to determine the basic phenomenum of design. Two criteria are applied to define the basic values of design for extreme meteorological variables. The first one determines the expected extreme value: it is obtained from analyzing the recurence of the phenomenum in a convened period of time, wich may be generally of 50 years. The second one determines the extreme value of low probability, taking into account the nuclear power plant's operating life -f.ex. 25 years- and considering, during said lapse, the occurrence probabilities of extreme meteorological phenomena. The values may be determined either by the deterministic method, which is based on the acknowledgement of the fundamental physical characteristics of the phenomena or by the probabilistic method, that aims to the analysis of historical statistical data. Brief comments are made on the subject in relation to the Argentine Republic area. (R.J.S.) [es

The oral health status of children with congenital heart diseases and the parental awareness on maintaining good oral health and attitude towards preventive dental health measures were evaluated. A total of 170 children between the age group of 1-16 yrs belonging to both genders, with the history of congenital heart disease from Sree Chitra Tirunal Institute of Medical Science and Technology, Thiruvananthapuram and Narayana Hrudayalaya Institute of Medical Sciences, Bangalore were examined. Oral lesions and caries experience were recorded using modified WHO oral health assessment form. Oral hygiene of the children with congenital heart disease was found to be poor with tongue coating (50.6%), plaque (41.8%), calculus (35.3%), and caries (42.4%). Parental awareness on the importance of maintaining good oral hygiene, preventive dentistry, medicinal decay and its systemic effects has been found to be very poor. Dentistry should give priority to patients whose general health may be put at risk by poor dental health. Closer cooperation between Pediatrician, Pediatric Cardiologists and Pediatric Dentists could help improve dental care for these children.

The extreme ultraviolet spectroscope EXCEED (EXtrem ultraviolet spetrosCope for ExosphEric Dynamics) on board the Hisaki satellite was launched in September 2013 from the Uchinoura space center, Japan. It is orbiting around the Earth with an orbital altitude of around 950-1150 km. This satellite is dedicated to and optimized for observing the atmosphere and magnetosphere of terrestrial planets such as Mercury, Venus, Mars, as well as Jupiter. The instrument consists of an off axis parabolic entrance mirror, switchable slits with multiple filters and shapes, a toroidal grating, and a photon counting detector, together with a field of view guiding camera. The design goal is to achieve a large effective area but with high spatial and spectral resolution. Based on the after-launch calibration, the spectral resolution of EXCEED is found to be 0.3-0.5 nm FWHM (Full Width at Half Maximum) over the entire spectral band, and the spatial resolution is around 17". The evaluated effective area is larger than 1cm2. In this presentation, the basic concept of the instrument design and the observation technique are introduced. The current status of the spacecraft and its future observation plan are also shown.

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.

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

Muscle strength and standing balance decrease in patients with Multiple Sclerosis (MS). The aim of the present study was to investigate the relationship between the lower extremity isometric muscle strength and standing balance in patients with MS. Forty-seven patients with MS and 10 healthy volunteers were included. Neurological disability level was assessed using Expanded Disability Status Scale (EDSS). Isometric strength of seven lower extremity muscles (hip flexor-extensor-abductor-adductor, knee flexor-extensor, and ankle dorsal flexor) was assessed using hand-held dynamometer. Duration of static one-leg standing balance was measured using digital chronometer. Hip flexor-extensor-abductor-adductor, knee flexor-extensor, and ankle dorsal flexor isometric muscle strength, and duration of one-leg standing balance were decreased in patients with MS when compared with controls (p isometric muscle strength and EDSS level was related duration of one-leg standing balance in patients with MS. All assessed lower extremity isometric muscle strength (except ankle dorsal flexor) was related with EDSS. Hip flexor-extensor-abductor-adductor, knee flexor-extensor, and ankle dorsal flexor isometric muscle strength decreases in ambulatory MS patients. Lower extremity muscle weakness and neurological disability level are related with imbalance in MS population. Hip and knee region muscles weakness increases the neurological disability level. For the better balance and decrease neurological disability level whole lower extremity muscle strengthening should be included in rehabilitation programs.

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)

The European FP7 SafeWind Project aims at developing research towards a European vision of wind power forecasting, which requires advanced meteorological support concerning extreme wind events. This study is focused mainly on early warnings of extreme winds in the early medium-range. Three synoptic...... regimes. Overall, it becomes clear that the first indications of an extreme wind event might come from the ECMWF deterministic and/or probabilistic components capturing very intense weather systems (possible windstorms) in the medium term. For early warnings, all available EPS Extreme Forecast Index (EFI......) formulations were used, by linking daily maximum wind speeds to EFI values for different forecast horizons. From all possible EFI schemes deployed for issuing early warnings, the highest skill was found for the Gust Factor formulation (EFI-10FGI). Using EFI-10FGI, the corresponding 99% threshold could provide...

In addition, to explore the association between age, gender, height, educational level and different aspects of health status of adults with short stature. Methods A questionnaire was mailed to 72 subjects with short stature registered in the database of a Norwegian resource centre for rare disorders, response rate 61% (n = 44, age 16–61. Health status was assessed with SF-36 version 2. Comparison was done with age and gender matched samples from the general population in Norway (n = 264 and from subjects with RA (n = 88. Results The ShSt sample reported statistically significant impaired health status in all SF-36 subscales compared with the GP sample, most in the physical functioning, Mean Difference (MD 34 (95% Confidence Interval (CI 25–44. The ShSt reported poorer health status in mental health, MD 11 (95% CI 4–18 and social functioning, MD 11 (95% CI 2–20 but better in role physical MD 13 (95% CI 1–25 than the RA sample. On the other subscales there were minor difference between the ShSt and the RA sample. Within the short stature group there was a significant association between age and all SF-36 physical subcales, height was significantly associated with physical functioning while level of education was significantly associated with mental health. Conclusion People with short stature reported impaired health status in all SF-36 subscales indicating that they have health problems that influence their daily living. Health status seems to decline with increasing age, and earlier than in the general population.
Causes, Consequences and Public Health Implications of Low B-Vitamin Status in Ageing

Full Text Available The potential protective roles of folate and the metabolically related B-vitamins (vitamins B12, B6 and riboflavin in diseases of ageing are of increasing research interest. The most common cause of folate and riboflavin deficiencies in older people is low dietary intake, whereas low B12 status is primarily associated with food-bound malabsorption, while sub-optimal vitamin B6 status is attributed to increased requirements in ageing. Observational evidence links low status of folate and the related B-vitamins (and/or elevated concentrations of homocysteine with a higher risk of degenerative diseases including cardiovascular disease (CVD, cognitive dysfunction and osteoporosis. Deficient or low status of these B-vitamins alone or in combination with genetic polymorphisms, including the common MTHFR 677 C → T polymorphism, could contribute to greater disease risk in ageing by causing perturbations in one carbon metabolism. Moreover, interventions with the relevant B-vitamins to optimise status may have beneficial effects in preventing degenerative diseases. The precise mechanisms are unknown but many have been proposed involving the role of folate and the related B-vitamins as co-factors for one-carbon transfer reactions, which are fundamental for DNA and RNA biosynthesis and the maintenance of methylation reactions. This review will examine the evidence linking folate and related B-vitamins with health and disease in ageing, associated mechanisms and public health implications.

The aim of this study was to validate the diagnostic feasibility of a novel scoring system of peripheral arterial disease (PAD) in smokers and patients with diabetes depending on duplex Doppler sonographic features. Patients presenting with the symptomatology of PAD were divided into three groups: diabetes only, smoking only, and smokers with diabetes. The patients were clinically examined, a clinical severity score was obtained, and the subjects were categorized into the three extrapolated categories of mild, moderate, and severe. All 106 subjects also underwent a thorough duplex Doppler examination, and various aspects of PAD were assessed and tabulated. These components were used to create a novel duplex Doppler scoring system. Depending on the scores obtained, each individual was categorized as having mild, moderate, or severe illness. The Cohen kappa value was used to assess interobserver agreement between the two scoring systems. Interobserver agreement between the traditional Rutherford clinical scoring system and the newly invented duplex Doppler scoring system showed a kappa value of 0.83, indicating significant agreement between the two scoring systems (P<0.001). Duplex Doppler imaging is an effective screening investigation for lower extremity arterial disease, as it not only helps in its diagnosis, but also in the staging and grading of the disease, providing information that can be utilized for future management and treatment planning.

2001-01-01

We explore a new general-purpose heuristic for finding high-quality solutions to hard discrete optimization problems. The method, called extremal optimization, is inspired by self-organized criticality, a concept introduced to describe emergent complexity in physical systems. Extremal optimization successively updates extremely undesirable variables of a single suboptimal solution, assigning them new, random values. Large fluctuations ensue, efficiently exploring many local optima. We use extremal optimization to elucidate the phase transition in the 3-coloring problem, and we provide independent confirmation of previously reported extrapolations for the ground-state energy of ±J spin glasses in d=3 and 4

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 Corresponding CVD prevalence rates among individuals with diabetes were 15.3% vs. 12.6% (p = 0.364). For individuals without diabetes, the odds ratio (OR) for CVD in the ethnic minority groups remained significantly higher (range 1.5-2.6) than ethnic Norwegians (p employment, and body height, except for Turkish individuals. Regardless of diabetes status, obesity and physical inactivity were prevalent in the majority of ethnic minority groups, whereas systolic- and diastolic- blood pressures were higher in Norwegians. In nearly all ethnic groups, individuals with diabetes had higher triglycerides, waist-to-hip ratio (WHR), and body mass index compared to individuals without diabetes. Age, diabetes, hypertension, hypercholesterolemia, and WHR were significant predictors of CVD in both ethnic Norwegians and ethnic minorities, but significant ethnic differences were found for age, diabetes, and hypercholesterolemia. Conclusions Ethnic differences

First record of black band disease in the Hawaiian archipelago: response, outbreak status, virulence, and a method of treatment.

Full Text Available 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 termed Montipora 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.

There is overwhelming indirect evidence that dark matter exists, however, the dark matter particle has not yet been directly detected in laboratory experiments. In order to be able to identify the rare dark matter interactions with the target nuclei, such instruments have to feature a very low threshold and an extremely low radioactive background. They are therefore installed in underground laboratories to reduce cosmic ray backgrounds. I will review the status of direct dark matter searches and will discuss the perspectives for the future.

Full Text Available Historically speaking, metal music has always been about provoking a strong reaction. Depending on the characteristics of different sub-genres, one can focus on the sound, technique, visual appearance, and furthermore, the ideologies and ideas that are the foundation for each of the sub-genres. Although the majority of the metal community rejects accusations of being racially intolerant, some ideologies of extreme sub-genres (such as black metal are in fact formed around the ideas of self-conscious elitism expressed through interest in pagan mythology, racism, Nazism and fascism. There has been much interest in the Nazi era within the extreme metal scene thus influencing other sub-genres and artists. The aim of this paper is to examine various appearances of extreme narratives such as Nazism and racism in different sub-genres of metal, bearing in mind variations dependent on geographical, political, and other factors.
Extremal surface barriers

We present a generic condition for Lorentzian manifolds to have a barrier that limits the reach of boundary-anchored extremal surfaces of arbitrary dimension. We show that any surface with nonpositive extrinsic curvature is a barrier, in the sense that extremal surfaces cannot be continuously deformed past it. Furthermore, the outermost barrier surface has nonnegative extrinsic curvature. Under certain conditions, we show that the existence of trapped surfaces implies a barrier, and conversely. In the context of AdS/CFT, these barriers imply that it is impossible to reconstruct the entire bulk using extremal surfaces. We comment on the implications for the firewall controversy
Prodrugs for the Treatment of Neglected Diseases

Lorena Blau

2007-03-01

Full Text Available Recently, World Health Organization (WHO and Medicins San Frontieres (MSF proposed a classification of diseases as global, neglected and extremely neglected. Global diseases, such as cancer, cardiovascular and mental (CNS diseases represent the targets of the majority of the R&D efforts of pharmaceutical companies. Neglected diseases affect millions of people in the world yet existing drug therapy is limited and often inappropriate. Furthermore, extremely neglected diseases affect people living under miserable conditions who barely have access to the bare necessities for survival. Most of these diseases are excluded from the goals of the R&D programs in the pharmaceutical industry and therefore fall outside the pharmaceutical market. About 14 million people, mainly in developing countries, die each year from infectious diseases. From 1975 to 1999, 1393 new drugs were approved yet only 1% were for the treatment of neglected diseases [3]. These numbers have not changed until now, so in those countries there is an urgent need for the design and synthesis of new drugs and in this area the prodrug approach is a very interesting field. It provides, among other effects, activity improvements and toxicity decreases for current and new drugs, improving market availability. It is worth noting that it is essential in drug design to save time and money, and prodrug approaches can be considered of high interest in this respect. The present review covers 20 years of research on the design of prodrugs for the treatment of neglected and extremely neglected diseases such as ChagasÃ¢Â€Â™ disease (American trypanosomiasis, sleeping sickness (African trypanosomiasis, malaria, sickle cell disease, tuberculosis, leishmaniasis and schistosomiasis.

To examine differences in outcomes of patients after lower-extremity joint replacement across 3 post-acute care (PAC) rehabilitation settings. Prospective observational cohort study. Skilled nursing facilities (SNFs; n=5), inpatient rehabilitation facilities (IRFs; n=4), and home health agencies (HHAs; n=6) from 11 states. Patients with total knee (n=146) or total hip replacement (n=84) not related to traumatic injury. None. Self-care and mobility status at PAC discharge measured by using the Inpatient Rehabilitation Facility Patient Assessment Instrument. Based on our study sample, HHA patients were significantly less dependent than SNF and IRF patients at admission and discharge in self-care and mobility. IRF and SNF patients had similar mobility levels at admission and discharge and similar self-care at admission, but SNF patients were more independent in self-care at discharge. After controlling for differences in patient severity and length of stay in multivariate analyses, HHA setting was not a significant predictor of self-care discharge status, suggesting that HHA patients were less medically complex than SNF and IRF patients. IRF patients were more dependent in discharge self-care even after controlling for severity. For the full discharge mobility regression model, urinary incontinence was the only significant covariate. For the patients in our U.S.-based study, direct discharge to home with home care was the optimal strategy for patients after total joint replacement surgery who were healthy and had social support. For sicker patients, availability of 24-hour medical and nursing care may be needed, but intensive therapy services did not seem to provide additional improvement in functional recovery in these patients.

Full Text Available Objective: Oxidative stress in obese children may lead in adulthood serious conditions such as coronary heart diseases or type 2 diabetes mellitus. In childhood oxidative stress is associated with insulin resistance or extreme obesity. In this study, we aimed to evaluate oxidative stress status in moderately obese children without insulin resistance. Methods: A total of 38 obese children (21 male, 17 female without insulin resistance, mean aged 9.4±3.8 years and 51 normal weight children (25 male, 26 female as the control group, mean aged 9.3±3.9 years were enrolled to the study. Total oxidative status (TOS, total antioxidant capacity (TAC were measured and oxidative stress index (OSI was calculated. Results: The results reveal that obese children had lower TAC than normal weight children (2,27±0,28 vs. 2.76±0.35 mmol Trolox Eq./L; p<0,001. There was no statistical difference between obese and control groups regarding TOS (6,08±3,63 vs 5.25±4.16 μmol H2O2 Eq./L; p=0.333. OSI was higher in obese group (2.65±1.52 vs 1.92±1.56; p=0.029 Conclusion: Balance between oxidant and antioxidant system is disrupted due to the reduced TAC even in moderately obese children without insulin resistance. Further studies should also be performed to evaluate the beneficial effects of dietary intake of antioxidants in these children.

Multiple factors including gastroesophageal reflux disease (GERD) were evaluated for a case-control study in Chonnam area to investigate the causative entity of COPD. Data on the multiple causative factors from hospital records and interview survey were analyzed in three groups of COPD (64 cases as case group), normal lung (83 cases as control group 1) and non-COPD lung disease (45 case as control group 2). Smoking status, history of adulthood pulmonary infection and frequent history of URI, socioeconomic status, and GERD were significant different between COPD group and control group 1. Drinking status, physical height of the subjects and GERD were significant different between COPD group and control group 2. If control group 1 was used, odds ratio of GERD and COPD was 5.68 (95% confidence interval, 95% CI: 2.59-12.45) and 4.81 (95% CI: 1.89-10.53) when adjusted by age and smoking status. If control group 2 was used, odds ratio of GERD and COPD was 4.22 (95% CI: 1.69-10.56) and 4.59 (95% CI: 1.64-12.86) when adjusted by alcohol and adulthood respiratory infection status. In summary, there result suggested that GERD might play a causative role in the development of COPD.

Drinking status, physical height of the subjects and GERD were significant different between COPD group and control group 2. If control group 1 was used, odds ratio of GERD and COPD was 5.68 (95% confidence interval, 95% CI: 2.59-12.45) and 4.81 (95% CI: 1.89-10.53) when adjusted by age and smoking status. If control group 2 was used, odds ratio of GERD and COPD was 4.22 (95% CI: 1.69-10.56) and 4.59 (95% CI: 1.64-12.86) when adjusted by alcohol and adulthood respiratory infection status. In summary, there result suggested that GERD might play a causative role in the development of COPD

Undiagnosed and untreated celiac disease (CD) constitutes an increasing skeletal health problem due to its association with low bone density and fractures. Examinations of skeletal status in children using dual-energy X-ray absorptiometry (DXA) are prone to size-related misinterpretation. In contrary, the analysis of muscle-bone relationship seems to limit a possibility of misdiagnosis because skeletal status is evaluated from the functional perspective. The study was aimed to assess skeletal status of children suffering from CD with the use of muscle-bone functional algorithm. The study group comprised 29 celiac patients (13.7yr+/-2.9) on gluten-free diet (GFD), and 24 newly diagnosed atypical celiac patients, including subgroup with normal height (n=14; 12.6yr+/-3.9) and subgroup with short stature (n=10; 12.2yr+/-2.9). Muscular and skeletal status was evaluated by DXA (DPX-L, GE). Anthropometry, total body bone mineral density (TBBMD, g/cm(2)). and total body bone mineral content (TBBMC, g) as well as lean body mass (LBM, g) were evaluated. Muscle-bone interactions were estimated using TBBMC/LBM ratio. Previously established references for healthy controls were used for the calculation of Z-scores (age-matched) and SD-scores (height-matched). GFD treated celiacs and atypical celiacs with normal body height had TBBMD, TBBMC, LBM, and TBBMC/LBM ratio Z-scores and SD-scores within normal range for healthy controls. In contrary, atypical celiacs with short stature had significantly lower Z-scores for TBBMD (-2.3+/-0.4), TBBMC (-2.1+/-0.3), LBM (-1.4+/-0.3). and TBBMC/LBM ratio (-2.3+/-0.6) when compared to respective values observed in GFD treated celiacs (pnormal height (pvalues observed in GFD treated celiacs (+0.04+/-0.2; pnormal height (-0.4+/-0.2; pvalues of DXA assessed indicators of bone and muscle status as well as normal muscle-bone interactions. Untreated atypical celiacs may present a broad spectrum of heterogeneous abnormalities from normal to markedly

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.

Background Current instruments used to measure disease activity and health-related quality of life (HRQOL) in patients with Crohn’s disease (CD) and ulcerative colitis (UC) are often cumbersome, time-consuming, and expensive; although used in clinical trials, they are not convenient for clinical practice. A numeric rating scale (NRS) is a quick, inexpensive, and convenient patient-reported outcome (PRO) that can capture the patient’s overall perception of health. Aims To assess the validity, reliability, and responsiveness of an NRS and evaluate its use in clinical practice in patients with CD and UC. Methods We prospectively evaluated patient-reported NRS scores and measured correlations between NRS and a range of severity measures, including physician-reported NRS, Crohn’s disease activity index (CDAI), Harvey-Bradshaw index (HBI), inflammatory bowel disease questionnaire (IBDQ), and C-reactive protein (CRP) in patients with CD. Subsequently, we evaluated the correlation between the NRS and standard measures of health status (HBI or simple colitis clinical activity index [SCCAI]) and laboratory tests (sedimentation rate [ESR], CRP, and fecal calprotectin) in patients with CD and UC. Results The patient-reported NRS showed excellent correlation with CDAI (R2=0.59, p<0.0001), IBDQ (R2=0.66, p<0.0001), and HBI (R2=0.32, p<0.0001) in patients with CD. The NRS showed poor, but statistically significant correlation with SCCAI (R2=0.25, p<0.0001) in patients with UC. The NRS did not correlate with CRP, ESR, or calprotectin. The NRS was reliable and responsive to change. Conclusions The NRS is a valid, reliable, and responsive measure that may be useful to evaluate patients with CD and possibly UC. PMID:23250673

Abstract Vascular involvement can be seen in up to 40% of patients with Behcet syndrome (BS), the lower-extremity vein thrombosis (LEVT) being the most common type. The aim of the current study was to compare venous Doppler findings and clinical features between BS patients with LEVT and control patients diagnosed as having LEVT due to other causes. All consecutive 78 patients (71 men, 7 women; mean age 38.6 ± 10.3 years) with LEVT due to BS and 50 control patients (29 men, 21 women; mean age 42.0 ± 12.5 years) who had LEVT due to other causes, or idiopathic, were studied with the help of a Doppler ultrasonography after a detailed clinical examination. Patterns of venous disease were identified by cluster analyses. Clinical features of chronic venous disease were assessed using 2 classification systems. Venous claudication was also assessed. Patients with BS were more likely to be men, had significantly earlier age of onset of thrombosis, and were treated mainly with immunosuppressives and less frequently with anticoagulants. Furthermore, they had significantly more bilateral involvement, less complete recanalization, and more frequent collateral formation. While control patients had a disorganized pattern of venous involvement, BS patients had a contiguous and symmetric pattern, involving all deep and superficial veins of the lower extremities, with less affinity for crural veins. Clinical assessment, as measured by the 2 classification systems, also indicated a more severe disease among the BS patients. In line, 51% of the BS patients suffered from severe post-thrombotic syndrome (PTS) and 32% from venous claudication, whereas these were present in 8% and 12%, respectively, among the controls. Among BS patients, a longer duration of thrombosis, bilateral femoral vein involvement, and using no anticoagulation along with immunosuppressive treatment when first diagnosed were found to be associated independently with severe PTS.

The Asia Pacific region is regarded as the most disaster-prone area of the world. Since 2000, 1.2 billion people have been exposed to hydrometeorological hazards alone through 1215 disaster events. The impacts of climate change on meteorological phenomena and environmental consequences are well documented. However, the impacts on health are more elusive. Nevertheless, climate change is believed to alter weather patterns on the regional scale, giving rise to extreme weather events. The impacts from extreme weather events are definitely more acute and traumatic in nature, leading to deaths and injuries, as well as debilitating and fatal communicable diseases. Extreme weather events include heat waves, cold waves, floods, droughts, hurricanes, tropical cyclones, heavy rain, and snowfalls. Globally, within the 20-year period from 1993 to 2012, more than 530 000 people died as a direct result of almost 15 000 extreme weather events, with losses of more than US$2.5 trillion in purchasing power parity. © 2015 APJPH.

Our understanding of physics at very early Universe, as early as 10-35 s after the Big Bang, relies on the scenario known as the inflationary cosmology. Inflation predicts a particular polarization pattern in the cosmic microwave background, known as the B-mode yet the strength of such polarization pattern is extremely weak. To search for the B-mode of the polarization in the cosmic microwave background, we are constructing an off-axis rotating telescope to mitigate systematic effects as well as to maximize the sky coverage of the observation. We will discuss the present status of the GroundBIRD telescope.

This study examines a trauma-like model of potentially violent political extremism among Jewish Israelis. We study the psychosocial characteristics of political extremists that may lie at the root of sociopolitical instability and assess personal (gender, stressful life events, Holocaust family background, and political activism) and psychological parameters (self- and political transcendence, perceived political threats, in/out-group identification ratio) that may predict readiness to engage in destructive political behavior. We examine the ideological zeal of various political groups, the relationship between the latter and perceived political threats, and the predictors of extreme political activism. Results showed that the extreme political poles displayed high level of ideological and morbid transcendence. Right extremists displayed higher perceived threats to physical existence and national identity. Left extremists scored highest on perceived moral integrity threat. Higher perceived threats to national identity and moral integrity, risk, and self-transcendence statistically explain morbid transcendence. When fear conjures up extremely skewed sociopolitical identifications across political boundaries, morbid transcendence may manifest itself in destructive political activity. © 2010 Association for Research in Nervous and Mental Disease.

The seasonal trend of out-of-hospital coronary death (OHCD) and sudden cardiac death has been observed, but whether extreme temperature serves as a risk factor is rarely investigated. We therefore aimed to evaluate the impact of extreme temperatures on OHCDs in China. We obtained death records of 126,925 OHCDs from six large Chinese cities (Harbin, Beijing, Tianjin, Nanjing, Shanghai and Guangzhou) during the period 2009-2011. The short-term associations between extreme temperature and OHCDs were analysed with time-series methods in each city, using generalised additive Poisson regression models. We specified distributed lag non-linear models in studying the delayed effects of extreme temperature. We then applied Bayesian hierarchical models to combine the city-specific effect estimates. The associations between extreme temperature and OHCDs were almost U-shaped or J-shaped. The pooled relative risks (RRs) of extreme cold temperatures over the lags 0-14 days comparing the 1st and 25th centile temperatures were 1.49 (95% posterior interval (PI) 1.26-1.76); the pooled RRs of extreme hot temperatures comparing the 99th and 75th centile temperatures were 1.53 (95% PI 1.27-1.84) for OHCDs. The RRs of extreme temperature on OHCD were higher if the patients with coronary heart disease were old, male and less educated. This multicity epidemiological study suggested that both extreme cold and hot temperatures posed significant risks on OHCDs, and might have important public health implications for the prevention of OHCD or sudden cardiac death.

Evidence suggests that dietary fiber benefits patients with chronic kidney disease (CKD); however, this conclusion requires further validation. In this study, we examined the effects of dietary fiber on kidney function, inflammation, indoxyl sulfate, nutritional status, and cardiovascular risk in patients with advanced CKD. We performed linear regressions to assess the association between dietary fiber intake and CKD parameters. The aforementioned parameters were compared over an 18-month follow- up period. Kaplan-Meier analysis was used to investigate the association between fiber intake and Cardiac vascular disease (CVD). In total, 157 patients were included in this study. Dietary fiber and inflammatory indices were associated (interleukin [IL]-6: β=-0.024, p=0.035). The differential estimated glomerular filtration rate (ΔeGFR) as well as levels of C-reactive protein, IL-6, indoxyl sulfate, and serum cholesterol in the higher fiber intake (>=25 g/day) group were lower than those in the lower fiber intake (patients in the higher protein intake group (pintake may be a protective factor associated with CVD (hazard ratio=0.537 and 0.305- 0.947). The protein nutritional status was not different between the two groups (p>0.05). Our results suggest that increasing fiber intake can retard the decrease in the eGFR; can reduce the levels of proinflammatory factors, indoxyl sulfate, and serum cholesterol; and is negatively associated with cardiovascular risk, but does not disrupt the nutritional status of patients with CKD.

Prediction of survival in patients having surgery for metastatic bone disease in the extremities (MBDex) has been of interest in more than two decades. Hitherto no consensus on the value of biochemical variables has been achieved. Our purpose was (1) to investigate if standard biochemical variables have independent prognostic value for survival after surgery for MBDex and (2) to identify optimal prognostic cut off values for survival of biochemical variables. In a consecutive cohort of 270 patients having surgery for MBDex, we measured preoperative biochemical variables: hemoglobin, alkaline phosphatase, C-reactive protein and absolute, neutrophil and lymphocyte count. ROC curve analyses were performed to identify optimal cut off levels. Independent prognostic factors for variables were addressed with multiple Cox regression analyses. Optimal cut off levels were identified as: hemoglobin 7.45 mmol/L, absolute lymphocyte count 8.5 × 10 9 /L, neutrophil 5.68 × 10 9 /L, lymphocyte 1.37 × 10 9 /L, C-reactive protein 22.5 mg/L, and alkaline phosphatase 129 U/L. Regression analyses found alkaline phosphatase (HR 2.49) and neutrophil count (HR 2.49) to be independent prognostic factors. We found neutrophil count and alkaline phosphatase to be independent prognostic variables in predicting survival in patients after surgery for MBDex. © 2016 Wiley Periodicals, Inc.

An integrated case management (ICM) approach (ergonomic and problem-solving intervention) to work-related upper-extremity disorders was examined in relation to patient satisfaction, future symptom severity, function, and return to work (RTW). Federal workers with work-related upper-extremity disorder workers' compensation claims (n = 205) were randomly assigned to usual care or ICM intervention. Patient satisfaction was assessed after the 4-month intervention period. Questionnaires on clinical outcomes and ergonomic exposure were administered at baseline and at 6- and 12-months postintervention. Time from intervention to RTW was obtained from an administrative database. ICM group assignment was significantly associated with greater patient satisfaction. Regression analyses found higher patient satisfaction levels predicted decreased symptom severity and functional limitations at 6 months and a shorter RTW. At 12 months, predictors of positive outcomes included male gender, lower distress, lower levels of reported ergonomic exposure, and receipt of ICM. Findings highlight the utility of targeting workplace ergonomic and problem solving skills.

Full Text Available Abstract Background Due to climate change, extreme weather events have an incremental impact on human health. Injuries and mental health disorders are a particular burden of disease, which is broadly investigated in high income countries. Most distressed populations are, however, those in developing countries. Therefore, this study investigates mental and physical health impacts arising from extreme weather events in these populations. Method Post-traumatic Stress Disorder (PTSD, injury [primary outcomes], anxiety and depressive disorders [secondary outcomes], caused by weather extremes were systematically analyzed in people of developing countries. A systematic review of observational studies was conducted searching six databases, complemented by hand search, and utilizing two search engines. Review processing was done independently by two reviewers. Prevalence rates were analyzed in a pre/post design; an additional semi-structured search was conducted, to provide reference data for studies not incorporating reference values. Results All 17 identified studies (70,842 individuals indicate a disease increase, compared to the reference data. Increase ranges from 0.7–52.6 % for PTSD, and from 0.3–37.3 % for injury. No studies on droughts and heatwaves were identified. All studies were conducted in South America and Asia. Conclusion There is an increased burden of psychological diseases and injury. This finding needs to be incorporated into activities of prevention, preparedness and general health care of those developing countries increasingly experiencing extreme weather events. There is also a gap in research in Africa (in quantity and quality of studies in this field and a predominant heterogeneity of health assessment tools. PROSPERO registration no.: CRD42014009109
Australian shellfish ecosystems: Past distribution, current status and future direction.

Full Text Available We review the status of marine shellfish ecosystems formed primarily by bivalves in Australia, including: identifying ecosystem-forming species, assessing their historical and current extent, causes for decline and past and present management. Fourteen species of bivalves were identified as developing complex, three-dimensional reef or bed ecosystems in intertidal and subtidal areas across tropical, subtropical and temperate Australia. A dramatic decline in the extent and condition of Australia's two most common shellfish ecosystems, developed by Saccostrea glomerata and Ostrea angasi oysters, occurred during the mid-1800s to early 1900s in concurrence with extensive harvesting for food and lime production, ecosystem modification, disease outbreaks and a decline in water quality. Out of 118 historical locations containing O. angasi-developed ecosystems, only one location still contains the ecosystem whilst only six locations are known to still contain S. glomerata-developed ecosystems out of 60 historical locations. Ecosystems developed by the introduced oyster Crasostrea gigas are likely to be increasing in extent, whilst data on the remaining 11 ecosystem-forming species are limited, preventing a detailed assessment of their current ecosystem-forming status. Our analysis identifies that current knowledge on extent, physical characteristics, biodiversity and ecosystem services of Australian shellfish ecosystems is extremely limited. Despite the limited information on shellfish ecosystems, a number of restoration projects have recently been initiated across Australia and we propose a number of existing government policies and conservation mechanisms, if enacted, would readily serve to support the future conservation and recovery of Australia's shellfish ecosystems.

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.

Extubation failure is one of the most serious complications in extremely low birth weight infants (ELBWI) on mechanical ventilation therapy. We performed a 5-year retrospective analysis to realize the status of extubation failure in ELBWI. Extubation failure was defined as requirements of re-intubation within 72 hours after extubation. The extubation failure rate was 21% (29/138). The mean birth body weight was 808.3 +/- 140.4 gm. The mean gestational age was 25.8 +/- 1.2 wks. The incidence of chronic lung disease (CLD) in infants with extubation failure was 100% (29/29). Apnea of prematurity 49% (14/29) and post-extubation atelectasis 39% (11/29) were the most common reasons for reintubation. The major microbiology findings which correlated with nosocomial pneumonia in infants with extubation failure were Acinetobacter baumanni (21%), Klebsiella pneumonia (21%), Pseudomonas aeroginosa (14%), and Methicillin resistant staphylococcus aureus (14%). In conclusion, post-extubation atelectasis and apnea were the most common reasons for reintubation. ELBWI with extubation failure had higher incidences of post-extubation atelectasis, CLD, and nosocomial pneumonia. Further prospective studies are needed in order to clarify the appropriate extubation program for ELBWI and to prevent post-extubation atelectasis and nosocomial pneumonia.
Scintigraphy in diagnostics of algodystrophy in the upper extremity: a review

Basing on the literature, the information concerning usefulness of the three phase scintigraphy in algodystrophy of the upper extremity, both in diagnostic and etiopathogenetic aspects were presented. Delayed image phase is the examination of the best value in the diagnostics of the condition (the highest sensitivity and specificity). Typical feature of algodystrophy on the bone scan is diffuse periarticular hyperfixation of the tracer, in many joints of the distal part of the extremity. Early phases of scintigraphy are valuable in staging of the disease (distinguishing between 1. and 2. stage), in choice of the method of the treatment (vasoconstrictive or vasodilatative) and in monitoring of the course of the treatment. Haemodynamic changes in dystrophic extremity, appearing in early phases, provide interesting information about the etiopathogenesis of algodystrophy. Prognostic implications of scintigraphy (the prediction of the possibility of algodystrophy developing and prediction of good result of the treatment) were mentioned. The method of quantitative analysis of the scans and the problems concerning the choice of proper region of interesting were discussed. (author). 20 refs, 1 tab

The etiology of PAOD is the most common cause of disability atherosclerotic arteries. Significantly reduces the quality of life (leading to limb amputation). Chronic renal insufficiency, diabetes and smoking are risk factors for progression of PAOD. In patients with claudication significantly reduced in active life reconstruction is indicated in the form of classical femoropopliteal bypass. Surgery may be supplemented or replaced transluminal percutaneous angioplasty (PTA). The aim of this retrospective study at the Department of Vascular Surgery and LF UPJS VUSCH, a. s. in Kosice in 2008 – 2010 was due to the ambiguous result of several previous studies, analyze and compare the results of the surgical and endovascular revascularisation in patients with peripheral artery disease of the lower extremities in the femoropopliteal region. We found that the use of bypass respectively endovascular angioplasty in patients with infra inguinal disability for 1 year follow-up did not lead to differences in clinical and technical success in primary and secondary patency of blood vessels, or in improving claudication interval between groups. There also were no differences in the need for revascularization or limb amputation within 1 year of performance. Use bypass was associated with a higher incidence of improving symptoms of critical limb ischemia and a higher incidence of hematoma following exercise. (author)
Hiccup: An Extremely Rare Presentation of Thyrotoxicosis of Graves’ Disease

Full Text Available Persistent hiccup is a rare but potentially severe condition that can be symptomatic of a variety of diseases or idiopathic. Most episodes last only a few minutes and are self-limited, but hiccup can get persistent and become a real problem for physician and patient alike. The center of hiccup may be activated by a great variety of stimuli travelling along different nerve pathways and bring different effecter responses. We report a case of persistent hiccup as a presentation of impending thyroid storm of Graves’ disease. Though the condition is rare, clinicians should remain alert to the possibility of this diagnosis.

The present investigation aimed at the identification of possible indicators of course, predictors, and etiologically relevant factors of psychogenic diseases. According to their complaints a sample of probands suffering from psychogenic impairment of medium degree (n = 240) was chosen out of a representative sample of an urban adult population (n = 528). This procedure should ensure a relatively high intraindividual variance of course of the criterion, since a sufficient variability of course seems improbable with chronic and severe psychogenic impaired or stabile healthy probands. Within 10 years the sample was investigated three times by psychodynamically trained physicians and psychologists. By means of cluster analysis the sample was subdivided in different types of course of psychogenic impairment. Both extreme types of course-the probands who showed the most positive and the most negative spontaneous longterm course-were investigated univariately and by means of a multivariate discriminant analysis with regard to potentially course determining variables. It became obvious that personality variables and conditions of early childhood considerably influenced the spontaneous longterm course of psychogenic impairment.
