  2. Global Uranium Supply Ensured for Long Term, New Report Shows

    International Nuclear Information System (INIS)

    2012-01-01

    Full text: Uranium resources and production are on the rise with the security of uranium supply ensured for the long term, according to a new report by the OECD Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA). Uranium 2011: Resources, Production and Demand, commonly referred to as the ''Red Book'', shows that total identified uranium resources have grown 12.5% since 2008. However, the costs of production have also increased, leading to reductions in lower cost category resources. These figures, which reflect the situation as of 1 January 2011, mean that total identified resources are sufficient for over 100 years of supply based on current requirements. Global uranium mine production increased by over 25% between 2008 and 2010 because of significantly increased production in Kazakhstan, currently the world's leading producer. The increased resource base has been achieved thanks to a 22% increase in uranium exploration and mine development expenditures between 2008 and 2010, which in 2010 totalled over $2 billion. Demand for uranium is expected to continue to rise for the foreseeable future. Although the Fukushima Daiichi nuclear accident has affected nuclear power projects and policies in some countries, nuclear power remains a key part of the global energy mix. Several governments have plans for new nuclear power plant construction, with the strongest expansion expected in China, India, the Republic of Korea and the Russian Federation. The speed and magnitude of growth in generating capacity elsewhere is still to be determined. By the year 2035, according to the joint NEA-IAEA Secretariat, world nuclear electricity generating capacity is projected to grow from 375 GWe net (at the end of 2010) to between 540 GWe net in the low demand case and 746 GWe net in the high demand case, increases of 44% and 99% respectively. Accordingly, world annual reactor-related uranium requirements are projected to rise from 63 875 tonnes of uranium metal

    Purpose - The purpose of this paper is to develop evident-based predictive no-show models considering patients' each past appointment status, a time-dependent component, as an independent predictor to improve predictability. Design/methodology/approach - A ten-year retrospective data set was extracted from a pediatric clinic. It consisted of 7,291 distinct patients who had at least two visits along with their appointment characteristics, patient demographics, and insurance information. Logistic regression was adopted to develop no-show models using two-thirds of the data for training and the remaining data for validation. The no-show threshold was then determined based on minimizing the misclassification of show/no-show assignments. There were a total of 26 predictive model developed based on the number of available past appointments. Simulation was employed to test the effective of each model on costs of patient wait time, physician idle time, and overtime. Findings - The results demonstrated the misclassification rate and the area under the curve of the receiver operating characteristic gradually improved as more appointment history was included until around the 20th predictive model. The overbooking method with no-show predictive models suggested incorporating up to the 16th model and outperformed other overbooking methods by as much as 9.4 per cent in the cost per patient while allowing two additional patients in a clinic day. Research limitations/implications - The challenge now is to actually implement the no-show predictive model systematically to further demonstrate its robustness and simplicity in various scheduling systems. Originality/value - This paper provides examples of how to build the no-show predictive models with time-dependent components to improve the overbooking policy. Accurately identifying scheduled patients' show/no-show status allows clinics to proactively schedule patients to reduce the negative impact of patient no-shows.

    29 patients showing moderate to markedly pronounced tardive dyskinesia (TD) and a further 29 control patients (C) under a similar long-term medication with neuroleptics that had been so chosen as to match the age and sex distributions of the former group were subjected to computered tomography, neurological examination and psychological testing. The results did not point to any correlations between the structural changes and duration of treatment and the clinical signs or symptoms of extrapyramidal disorder. This was taken as further evidence in support of the theory that the initial damage in tardive dyskinesia mainly is at the level of the basal ganglia. (orig./MG) [de

    Full Text Available OBJECTIVE: Evaluate whether exhaled nitric oxide may serve as a marker of intraoperative bronchospasm. INTRODUCTION: Intraoperative bronchospasm remains a challenging event during anesthesia. Previous studies in asthmatic patients suggest that exhaled nitric oxide may represent a noninvasive measure of airway inflammation. METHODS: A total of 146,358 anesthesia information forms, which were received during the period from 1999 to 2004, were reviewed. Bronchospasm was registered on 863 forms. From those, three groups were identified: 9 non-asthmatic patients (Bronchospasm group, 12 asthmatics (Asthma group and 10 subjects with no previous airway disease or symptoms (Control group. All subjects were submitted to exhaled nitric oxide measurements (parts/billion, spirometry and the induced sputum test. The data was compared by ANOVA followed by the Tukey test and Kruskal-Wallis followed by Dunn's test. RESULTS: The normal lung function test results for the Bronchospasm group were different from those of the asthma group (p <0.05. The median percentage of eosinophils in induced sputum was higher for the Asthma [2.46 (0.45-6.83] compared with either the Bronchospasm [0.55 (0-1.26] or the Control group [0.0 (0] (p <0.05; exhaled nitric oxide followed a similar pattern for the Asthma [81.55 (57.6-86.85], Bronchospasm [46.2 (42.0 -62.6] and Control group [18.7 (16.0-24.7] (p< 0.05. CONCLUSIONS: Non-asthmatic patients with intraoperative bronchospasm detected during anesthesia and endotracheal intubation showed increased expired nitric oxide.

    2017-12-01

    Soil temperature is an important determinant of many subterranean ecological processes including plant growth, nutrient cycling, and carbon sequestration. Soils are expected to warm in response to increasing global surface temperatures; however, despite the importance of soil temperature to ecosystem processes, less attention has been given to examining changes in soil temperature over time. We collected long-term (> 20 years) soil temperature records from approximately 50 sites globally, many with multiple depths (5 - 100 cm), and examined temperature trends over the last few decades. For each site and depth we calculated annual summer means and conducted non-parametric Mann Kendall trend and Sen slope analysis to assess changes in summer soil temperature over the length of each time series. The mean summer soil temperature trend across all sites and depths was not significantly different than zero (mean = 0.004 °C year-1 ± 0.033 SD), suggesting that soils have not warmed over the observation period. Of the subset of sites that exhibit significant increases in temperature over time, site location, depth of measurement, time series length, and neither start nor end date seem to be related to trend strength. These results provide evidence that the thermal regime of soils may have a stronger buffering capacity than expected, having important implications for the global carbon cycle and feedbacks to climate change.

    The article makes an attempt to detect main characteristics of status of modern patient on the basis of analysis of Russian and international materials. Nowadays, patient plays an active role both in process of receiving medical care and in issues of health policy and public health. The patient has many rights and modes to defend them. At the national and international levels, many organizations of patients exist and their authority and impact only increase. The globalization effects on structure of patients, because it brought facilitation of trans-borders travel and resulted in development of medical tourism and increase of migration. The structure of patients becomes more various in its national and ethnic belonging, cultural and language characteristics. This trend generated new requirements to training of medical personnel and functioning of health services. The globalization also enhances social economic inequity between patients and hence complicates accessibility of high quality medical care to population. The main traits of modern patient are to be studied and analyzed on all levels with purpose to develop an important basis for successful planning, reformation and development of public health.

    The two non-native grasses that have established long-term populations in Antarctica (Poa pratensis and Poa annua) were studied from a global multidimensional thermal niche perspective to address the biological invasion risk to Antarctica. These two species exhibit contrasting introduction histories and reproductive strategies and represent two referential case studies of biological invasion processes. We used a multistep process with a range of species distribution modelling techniques (ecological niche factor analysis, multidimensional envelopes, distance/entropy algorithms) together with a suite of thermoclimatic variables, to characterize the potential ranges of these species. Their native bioclimatic thermal envelopes in Eurasia, together with the different naturalized populations across continents, were compared next. The potential niche of P. pratensis was wider at the cold extremes; however, P. annua life history attributes enable it to be a more successful colonizer. We observe that particularly cold summers are a key aspect of the unique Antarctic environment. In consequence, ruderals such as P. annua can quickly expand under such harsh conditions, whereas the more stress-tolerant P. pratensis endures and persist through steady growth. Compiled data on human pressure at the Antarctic Peninsula allowed us to provide site-specific biosecurity risk indicators. We conclude that several areas across the region are vulnerable to invasions from these and other similar species. This can only be visualized in species distribution models (SDMs) when accounting for founder populations that reveal nonanalogous conditions. Results reinforce the need for strict management practices to minimize introductions. Furthermore, our novel set of temperature-based bioclimatic GIS layers for ice-free terrestrial Antarctica provide a mechanism for regional and global species distribution models to be built for other potentially invasive species. © 2017 John Wiley & Sons Ltd.

    Full Text Available Coronary collateral circulation protects cardiac tissues from myocardial infarction damage and decreases sudden cardiac death. So far, it is unclear how coronary collateralization varies by race-ethnicity groups and by sex.We assessed 868 patients with obstructive CAD. Patients were assessed for collateral grades based on Rentrop grading system, as well as other covariates. DNA samples were genotyped using the Affymetrix 6.0 genotyping array. To evaluate genetic contributions to collaterals, we performed admixture mapping using logistic regression with estimated local and global ancestry.Overall, 53% of participants had collaterals. We found difference between sex and racial-ethnic groups. Men had higher rates of collaterals than women (P-value = 0.000175. White Hispanics/Latinos showed overall higher rates of collaterals than African Americans and non-Hispanic Whites (59%, 50% and 48%, respectively, P-value = 0.017, and especially higher rates in grade 1 and grade 3 collateralization than the other two populations (P-value = 0.0257. Admixture mapping showed Native American ancestry was associated with the presence of collaterals at a region on chromosome 17 (chr17:35,243,142-41,251,931, β = 0.55, P-value = 0.000127. African ancestry also showed association with collaterals at a different region on chromosome 17 (chr17: 32,266,966-34,463,323, β = 0.38, P-value = 0.00072.In our study, collateralization showed sex and racial-ethnic differences in obstructive CAD patients. We identified two regions on chromosome 17 that were likely to harbor genetic variations that influenced collateralization.

    Viruses influence oceanic ecosystems by causing mortality of microorganisms, altering nutrient and organic matter flux via lysis and auxiliary metabolic gene expression and changing the trajectory of microbial evolution through horizontal gene transfer. Limited host range and differing genetic potential of individual virus types mean that investigations into the types of viruses that exist in the ocean and their spatial distribution throughout the world's oceans are critical to understanding the global impacts of marine viruses. Here we evaluate viral morphological characteristics (morphotype, capsid diameter and tail length) using a quantitative transmission electron microscopy (qTEM) method across six of the world's oceans and seas sampled through the Tara Oceans Expedition. Extensive experimental validation of the qTEM method shows that neither sample preservation nor preparation significantly alters natural viral morphological characteristics. The global sampling analysis demonstrated that morphological characteristics did not vary consistently with depth (surface versus deep chlorophyll maximum waters) or oceanic region. Instead, temperature, salinity and oxygen concentration, but not chlorophyll a concentration, were more explanatory in evaluating differences in viral assemblage morphological characteristics. Surprisingly, given that the majority of cultivated bacterial viruses are tailed, non-tailed viruses appear to numerically dominate the upper oceans as they comprised 51-92% of the viral particles observed. Together, these results document global marine viral morphological characteristics, show that their minimal variability is more explained by environmental conditions than geography and suggest that non-tailed viruses might represent the most ecologically important targets for future research.

    The usefulness of 99m Tc-HM-PAO SPECT in diagnosing epilepsy was studied. The subjects were 33 epileptic patients, ranging in age from 5 years and 5 months to 28 years and 3 months, who showed focal paroxysm on electroencephalograms. Lowered accumulation site was found on SPECT in 19 patients. Four patients with abnormal findings on X-ray CT or MRI showed lowered accumulation and focal paroxysm at the same site. Of 29 patients with normal X-ray CT or MRI findings, 15 (52%) showed lowered accumulation. Five patients showed a focal paroxysm at the site of lowered accumulation. In 8 patients the focal paroxysm site was partly coincided with the accumulation site. In some patients the focal site predicted by the findings of clinical symptoms and the lowered accumulation site coincided. SPECT is therefore a useful method in diagnosing a focal site in epilepsy and considered to reflect the severity of disease. (Y.S.)

    The mechanism underlying delusion in Alzheimer's disease patients has not been fully clarified; however, the occurrence of delusion is a critical issue for dementia patients and their caregivers. In Japan, delusion of theft is the most frequent delusion in AD patients. We examined the risk factors for delusion of theft in AD patients showing mild dementia. Fifty-six AD patients were administered HDS-R, MMSE and COGNISTAT, including the 'speech sample', to assess their neuropsychological and social cognitive functions. The age, years of education, presence of cohabiting family members and premorbid personality traits were obtained from family members. About 25.0% of AD patients showed delusion of theft (D-group), and 75% did not (non-D-group). About 33.3% of female patients and 5.9% of male patients were included in the D-group (p theft in AD patients was related to female gender, absence of cohabiting family members, neurotic personality and retained social cognitive function.

    Full Text Available ABSTRACT Objective To determine the association of a scored patient-generated Subjective Global Assessment with mortality and length of hospital stay in cancer patients. Methods Cross-sectional study carried out between July and September 2014 using secondary data collection using data from 366 medical records of patients admitted to a hospital recognized as a cancer center of excellence. The present study included patients with hospital stay over than or equal three days and minimum age of 20 years. The patient-generated Subjective Global Assessment scores were calculated and compared with the patients’ clinical and anthropometric characteristics and outcomes (death and long length of stay in hospital. Results Of the 366 patients evaluated, 36.0% were malnourished. The presence of malnutrition, according to the scored patient-generated Subjective Global Assessment, was statistically associated with the presence of metastasis (52.4%. On the other hand, malnutrition, according to the body mass index in adults (55.8% and in older elderly patients (54.2%, was associated with death (55.0%. The adjusted logistic regression model showed that the following factors were associated with prolonged hospitalization: early nutritional screening, presence of severe malnutrition, radiotherapy and chemotherapy, and surgical procedures. As for mortality, the associated factors were: male reproductive system tumor, presence of metastasis, clinical treatment, prolonged hospitalization, and the presence of some degree of malnutrition. Conclusion The patient-generated Subjective Global Assessment score is an important risk marker of prolonged hospitalization and mortality rates. It is a useful tool capable of circumventing significant biases in the nutritional evaluation of cancer patients.

    Introduction Comprehensive studies on the relationship between patient demographics and subsequent treatment and disposition at a single mass-gathering event are lacking. The Sydney Royal Easter Show (SRES; Sydney Olympic Park, New South Wales, Australia) is an annual, 14-day, agricultural mass-gathering event occurring around the Easter weekend, attracting more than 800,000 patrons per year. In this study, patient records from the SRES were analyzed to examine relationships between weather, crowd size, day of week, and demographics on treatment and disposition. This information would help to predict factors affecting patient treatment and disposition to guide ongoing training of first responders and to evaluate the appropriateness of staffing skills mix at future events. Hypothesis Patient demographics, environmental factors, and attendance would influence the nature and severity of presentations at the SRES, which would influence staffing requirements. A retrospective analysis of 4,141 patient record forms was performed for patients who presented to St John Ambulance (Australian Capital Territory, Australia) at the SRES between 2012 and 2014 inclusive. Presentation type was classified using a previously published minimum data set. Data on weather and crowd size were obtained from the Australian Bureau of Meteorology (Melbourne, Victoria, Australia) and the SRES, respectively. Statistical analyses were performed using SPSS v22 (IBM; Armonk, New York USA). Between 2012 to 2014, over 2.5 million people attended the SRES with 4,141 patients treated onsite. As expected, the majority of presentations were injuries (49%) and illnesses (46%). Although patient demographics and presentation types did not change over time, the duration of treatment increased. A higher proportion of patients were discharged to hospital or home compared to the proportion of patients discharged back to the event. Patients from rural/regional locations (accounting for 15% of all patients) were

  5. Chronic myeloid leukemia patients sensitive and resistant to imatinib treatment show different metabolic responses.

    Directory of Open Access Journals (Sweden)

    Jiye A

    Full Text Available The BCR-ABL tyrosine kinase inhibitor imatinib is highly effective for chronic myeloid leukemia (CML. However, some patients gradually develop resistance to imatinib, resulting in therapeutic failure. Metabonomic and genomic profiling of patients' responses to drug interventions can provide novel information about the in vivo metabolism of low-molecular-weight compounds and extend our insight into the mechanism of drug resistance. Based on a multi-platform of high-throughput metabonomics, SNP array analysis, karyotype and mutation, the metabolic phenotypes and genomic polymorphisms of CML patients and their diverse responses to imatinib were characterized. The untreated CML patients (UCML showed different metabolic patterns from those of healthy controls, and the discriminatory metabolites suggested the perturbed metabolism of the urea cycle, tricarboxylic acid cycle, lipid metabolism, and amino acid turnover in UCML. After imatinib treatment, patients sensitive to imatinib (SCML and patients resistant to imatinib (RCML had similar metabolic phenotypes to those of healthy controls and UCML, respectively. SCML showed a significant metabolic response to imatinib, with marked restoration of the perturbed metabolism. Most of the metabolites characterizing CML were adjusted to normal levels, including the intermediates of the urea cycle and tricarboxylic acid cycle (TCA. In contrast, neither cytogenetic nor metabonomic analysis indicated any positive response to imatinib in RCML. We report for the first time the associated genetic and metabonomic responses of CML patients to imatinib and show that the perturbed in vivo metabolism of UCML is independent of imatinib treatment in resistant patients. Thus, metabonomics can potentially characterize patients' sensitivity or resistance to drug intervention.

    Taking care of offspring during a prolonged period of time is probably one of the most stressful life experiences for parents. The present study compares the cortisol awakening response (CAR) in 38 long-term caregivers (mothers and fathers of schizophrenic relatives) with a control group of 32 non-caregivers. Factors such as general stress, caregiver burden, patient severity, and institutionalization were studied. Although a blunted CAR was observed in caregivers in comparison with controls, this difference was not significant. Among caregivers, the absence of institutionalization for the patient is associated with a lack of CAR in caregivers in comparison with caregivers of institutionally supported patients. General stress, caregiver burden, and patient severity themselves did not favor significant changes in CAR. CAR shows greater sensitivity to institutional support than patient severity and perceived stress. Further research is needed to explain the impact of these factors on health and the psychological factors involved.

    Full Text Available Abstract Background Infection with H. pylori is important in the etiology of gastric cancer. Gastric cancer is infrequent in Africa, despite high frequencies of H. pylori infection, referred to as the African enigma. Variation in environmental and host factors influencing gastric cancer risk between different populations have been reported but little is known about the biological differences between gastric cancers from different geographic locations. We aim to study genomic instability patterns of gastric cancers obtained from patients from United Kingdom (UK and South Africa (SA, in an attempt to support the African enigma hypothesis at the biological level. Methods DNA was isolated from 67 gastric adenocarcinomas, 33 UK patients, 9 Caucasian SA patients and 25 native SA patients. Microsatellite instability and chromosomal instability were analyzed by PCR and microarray comparative genomic hybridization, respectively. Data was analyzed by supervised univariate and multivariate analyses as well as unsupervised hierarchical cluster analysis. Results Tumors from Caucasian and native SA patients showed significantly more microsatellite instable tumors (p Conclusions Gastric cancers from SA and UK patients show differences in genetic instability patterns, indicating possible different biological mechanisms in patients from different geographical origin. This is of future clinical relevance for stratification of gastric cancer therapy.

    Full Text Available Objective : To verify the relationship between intracranial pressure and flash visual evoked potentials (F-VEP in patients with cryptococcal meningitis. Method The sample included adults diagnosed with cryptococcal meningitis admitted at a reference hospital for infectious diseases. The patients were subjected to F-VEP tests shortly before lumbar puncture. The Pearson’s linear correlation coefficient was calculated and the linear regression analysis was performed. Results : Eighteen individuals were subjected to a total of 69 lumbar punctures preceded by F-VEP tests. At the first lumbar puncture performed in each patient, N2 latency exhibited a strong positive correlation with intracranial pressure (r = 0.83; CI = 0.60 - 0.94; p < 0.0001. The direction of this relationship was maintained in subsequent punctures. Conclusion : The intracranial pressure measured by spinal tap manometry showed strong positive association with the N2 latency F-VEP in patients with cryptococcal meningitis.

    Nearly 20% of patients who have undergone total knee arthroplasty (TKA) report persistent poor knee function. This study explores the idea that, despite similar knee joint biomechanics, the neuro-motor synergies may be different between high-functional and low-functional TKA patients. We hypothesized that (1) high-functional TKA recruit a more complex neuro-motor synergy pattern compared to low-functional TKA and (2) high-functional TKA patients demonstrate more stride-to-stride variability (flexibility) in their synergies. Gait and electromyography (EMG) data were collected during level walking for three groups of participants: (i) high-functional TKA patients (n=13); (ii) low-functional TKA patients (n=13) and (iii) non-operative controls (n=18). Synergies were extracted from EMG data using non-negative matrix factorization. Analysis of variance and Spearman correlation analyses were used to investigate between-group differences in gait and neuro-motor synergies. Results showed that synergy patterns were different among the three groups. Control subjects used 5-6 independent neural commands to execute a gait cycle. High functional TKA patients used 4-5 independent neural commands while low-functional TKA patients relied on only 2-3 independent neural commands to execute a gait cycle. Furthermore, stride-to-stride variability of muscles' response to the neural commands was reduced up to 15% in low-functional TKAs compared to the other two groups. Copyright © 2017 Elsevier Ltd.

    Idiopathic inflammatory myopathies can be classified as polymyositis, dermatomyositis, immune-mediated necrotizing myopathy, sporadic inclusion body myositis or non-specific myositis. Anti-Jo-1 antibody-positive patients are assigned to either polymyositis or dermatomyositis suggesting overlapping pathological features. We aimed to determine if anti-Jo-1 antibody-positive myopathy has a specific morphological phenotype. In a series of 53 muscle biopsies of anti-Jo-1 antibody-positive patients, relevant descriptive criteria defining a characteristic morphological pattern were identified. They were tested in a second series of anti-Jo-1 antibody-positive patients and compared to 63 biopsies from patients suffering from other idiopathic inflammatory myopathies. In anti-Jo-1 antibody-positive patients, necrotic fibres, which strongly clustered in perifascicular regions, were frequently observed. Sarcolemmal complement deposition was detected specifically in perifascicular areas. Inflammation was mainly located in the perimysium and around vessels in 90.6%. Perimysial fragmentation was observed in 90% of cases. Major histocompatibility complex class I staining was diffusely positive, with a perifascicular reinforcement. Multivariate analysis showed that criteria defining perifascicular pathology: perifascicular necrosis, atrophy, and perimysial fragmentation allow the distinction of anti-Jo-1 antibody-positive patients, among patients suffering from other idiopathic inflammatory myopathies. Anti-Jo-1 antibody-positive patients displayed perifascicular necrosis, whereas dermatomyositis patients exhibited perifascicular atrophy. © The Author (2015).

    In acute ischemic stroke, diffusion weighted imaging (DWI) shows hyperintensities and is considered to indicate irreversibly damaged tissue. We present the case of a young stroke patient with unusual variability in the development of signal intensities within the same vessel territory. A 35-year-old patient presented with symptoms of global aphasia and hypesthesia of the left hand. MRI demonstrated a scattered lesion in the MCA territory. After rtPA therapy the patient received further MRI examination, three times on day 1, and once on day 2, 3, 5 and 43. The posterior part of the lesion showed the usual pattern with increasing DWI hyperintensity and decreased ADC, as well as delayed FLAIR positivity. However, the anterior part of the lesion, which was clearly visible in the first examination completely normalized on the first day and only reappeared on day 2. This was accompanied by a normalization of the ADC as well as an even further delayed FLAIR positivity. We showed that interim normalization of DWI and ADC in the acute phase can not only be found in rodent models of stroke, but also in humans. We propose that DWI lesion development might be more variable during the first 24 h after stroke than previously assumed

    Diabetes mellitus is an independent risk factor of cardiovascular disease. Diabetes is known to cause microangiopathy. The microangiopathy is hardly detectable on the coronary angiography. Myocardial perfusion imaging shows the resultant perfusion status which reflects the microangiopathy. For patients who underwent revascularization, the microangiopathy could affect the myocardial perfusion improvement. Diabetes patients probably experience the different myocardial perfusion improvement as compared to the non-diabetes patients although they have similar angiographic findings. The aim of this study is to find out whether there is a time-course difference of perfusion improvement between the diabetes and non diabetes patients who showed patent angiographic findings after coronary artery grafting surgery (CABG). A total of 129 patients who underwent coronary artery bypass grafting surgery were enrolled in this study. Myocardial SPECTs performed at previous, short-term (3 month), and mid-term (1 year) to CABG. One-year follow up angiography was done 411±121 days after surgery. Graft patency was determined according to the FitzGibbon et al. Segments were assigned to vascular territories using a 20 segment model. The segments of excellent patency were included in this study. Time course differences of concerned segments were analyzed using RMANOVA. The number of segments enrolled was 764 of diabetes and 1083 of non-diabetes. At short-term follow up, reversibility score was 2.8±8.1% in diabetes and 0.3±7.5% in non-diabetes. At long-term follow up, reversibility score was 1.8±8.0% in diabetes and 0.1±7.3% in non-diabetes. The time-course of reversibility score was significantly different between the diabetes and non diabetes (p<0.001) Diabetic segments showed high residual reversibility score than non-diabetic segments after CABG although the angiographic finding was patent in both groups. This result is maybe attributable to microangiopathy induced by diabetes

    Purpose: Cooperative groups have investigated the outcome of androgen deprivation therapy combined with radiation therapy in prostate cancer patients with variable pretreatment prognostic indicators. This report describes an objective means of selecting patients for adjuvant hormonal therapy by a retrospective matched case/control comparison of outcome between patients with specific pretreatment characteristics who receive adjuvant hormones (RT + H) vs. patients with identical pretreatment characteristics treated with radiation therapy alone (RT). In addition, this report shows the 5-year bNED control for patients selected by this method for RT + H vs. RT alone. Methods and Materials: From (10(88)) to (12(93)), 517 T1-T3 NXM0 patients with known pretreatment PSA level were treated at Fox Chase Cancer Center. Four hundred fifty-nine of those patients were treated with RT alone while 58 were treated with RT + H. The patients were categorized according to putative prognostic factors indicative of bNED control, which include the palpation stage, Gleason score, and pretreatment PSA. We compared actuarial bNED control rates according to treatment group within each of the prognostic groups. In addition, we devised a retrospective matched case/control selection of RT patients for comparison with the RT + H group. Five-year bNED control was compared for the two treatment groups, excluding the best prognosis group, using 56 RT + H patients and 56 matched (by stage, grade, and pretreatment PSA level) controls randomly selected from the RT alone group. bNED control for the entire group of 517 patients was then analyzed multivariately using step-wise Cox regression to determine independent predictors of outcome. Covariates considered for entry into the model included stage (T1/T2AB vs. T2C/T3), grade (2-6 vs. 7-10), pretreatment PSA (0-15 vs. > 15), treatment (RT vs. RT + H), and center of prostate dose. bNED failure is defined as PSA ≥1.5 ngm/ml and rising on two consecutive

    Portrayals of physicians on medical dramas have been the subject of research attention. However, such research has not examined portrayals of interactions between physicians and patients, has not compared physician portrayals on medical dramas versus on medical reality programs, and has not fully examined portrayals of physicians who are members of minority groups or who received their education internationally. This study content-analyzes 101 episodes (85 hours) of such programs broadcast during the 2006-2007 viewing season. Findings indicate that women are underrepresented as physicians on reality shows, though they are no longer underrepresented as physicians on dramas. However, they are not as actively portrayed in patient-care interactions as are male physicians on medical dramas. Asians and international medical graduates are underrepresented relative to their proportion in the U.S. physician population, the latter by almost a factor of 5. Many (but certainly not all) aspects of patient-centered communication are modeled, more so on reality programs than on medical dramas. Differences in patient-provider communication portrayals by minority status and gender are reported. Implications for public perception of physicians and expectations regarding provider-patient interaction are discussed.

    Full Text Available Abstract Background Elevated plasma cholesterol promotes the formation of atherosclerotic lesions in which monocyte-derived lipid-laden macrophages are frequently found. To analyze, if circulating monocytes already show increased lipid content and differences in lipoprotein metabolism, we compared monocytes from patients with Familial Hypercholesterolemia (FH with those from healthy individuals. Methods Cholesterol and oxidized cholesterol metabolite serum levels of FH and of healthy, gender/age matched control subjects were measured by combined gas chromatography – mass spectroscopy. Monocytes from patients with FH and from healthy subjects were isolated by antibody-assisted density centrifugation. Gene expression profiles of isolated monocytes were measured using Affymetrix HG-U 133 Plus 2.0 microarrays. We compared monocyte gene expression profiles from FH patients with healthy controls using a Welch T-test with correction for multiple testing (p Results Using microarray analysis we found in FH patients a significant up-regulation of 1,617 genes and a down-regulation of 701 genes compared to monocytes from healthy individuals. These include genes of proteins that are involved in the uptake, biosynthesis, disposition, and cellular efflux of cholesterol. In addition, plasma from FH patients contains elevated amounts of sterols and oxysterols. An increased uptake of oxidized as well as of native LDL by FH monocytes combined with a down-regulation of NPC1 and ABCA1 explains the lipid accumulation observed in these cells. Conclusion Our data demonstrate that circulating FH monocytes show differences in cell physiology that may contribute to the early onset of atherosclerosis in this disease.

    Bulimia nervosa (BN) emerges in the late teen years and is characterized by binge eating and related compensatory behaviors. These behaviors often co-occur with periods of negative affect suggesting an association between emotions and control over eating behavior. In the current study, we examined how cognitive control and neural processes change under emotional states of arousal in 46 participants with (n=19) and without (n=27) BN from the ages of 18-33 years. Participants performed a go/nogo task consisting of brief negative, positive and neutral emotional cues and sustained negative, positive and neutral emotional states of arousal during functional magnetic resonance imaging (fMRI). Overall task performance improved with age for healthy participants, but not for patients with BN. These age-dependent behavioral effects were paralleled by diminished recruitment of prefrontal control circuitry in patients with BN with age. Although patients with BN showed no difference in performance on the experimental manipulations of negative emotions, sustained positive emotions related to improved performance among patients with BN. Together the findings highlight a neurodevelopmental approach towards understanding markers of psychopathology and suggest that sustained positive affect may have potential therapeutic effects on maintaining behavioral control in BN.

    Systemic sclerosis is a multisystem autoimmune collagen disease where structural and functional abnormalities of small blood vessels prevail. Transient ischemic attacks, ischemic stroke, and hemorrhage have been reported as primary consequence of vascular central nervous system affection in systemic sclerosis. Magnetic resonance imaging is considered to be the most sensitive diagnostic technique for detecting symptomatic and asymptomatic lesions in the brain in cases of multifocal diseases. The objective of this study is to detect subclinical as well as clinically manifest cerebral vasculopathy in patients with systemic sclerosis using magnetic resonance imaging. As much as 30 female patients with systemic sclerosis aged 27-61 years old, with disease duration of 1-9 years and with no history of other systemic disease or cerebrovascular accidents, were enrolled. Age-matched female control group of 30 clinically normal subjects, underwent brain magnetic resonance examination. Central nervous system (CNS) involvement in the form of white matter hyperintense foci of variable sizes were found in significantly abundant forms in systemic sclerosis patients on magnetic resonance evaluation than in age-related control group, signifying a form of CNS vasculopathy. Such foci showed significant correlation to clinical features of organic CNS lesion including headaches, fainting attacks and organic depression as well as to the severity of peripheral vascular disease with insignificant correlation with disease duration. In conclusion, subclinical as well as clinically manifest CNS ischemic vasculopathy is not uncommon in systemic sclerosis patients and magnetic resonance imaging is considered a sensitive noninvasive screening tool for early detection of CNS involvement in patients with systemic sclerosis.

    This paper presents the basic rationale behind the development and testing of a multimodal communication aid especially designed for people suffering from global aphasia, and thus having severe expressive difficulties. The principle of the aid is to trigger patient associations by presenting...... various multimodal representations of communicative expressions. The aid can in this way be seen as a conceptual continuation of previous research within the field of communication aids based on uni-modal (pictorial) representations of communicative expressions. As patients suffering from global aphasia...... expressions can be used to support patients with global aphasia in communicating by means of short sentences with their surroundings. Only a limited evaluation is carried out, and as such no statistically significant results are obtained. The tests however indicate that the aid is capable of supporting...

In the case 2 it was observed a partial answer, with resistant pain to the analgesic ones and sharpen again crisis. In this case, both essays indicated hypersensitivity to the lR in the lymphocytes of the patient's outlying blood. It was concludes that the bio indicators of individual radiosensitivity can be of utility for the radioleisures prevention, by means of the personalized adaptation of therapeutic outlines that imply the use of IR. Also, in situations of accidental overexposure to IR, these indicators would have predict value, contributing to the design of therapeutic strategies. (Author)

    Noncommunicable diseases are the leading health concerns of the modern era, accounting for two-thirds of global deaths, half of all disability, and rapidly growing costs. To provide a contemporary overview of the burdens caused by noncommunicable diseases, we compiled mortality data reported by authorities in forty-nine countries for atherosclerotic cardiovascular diseases; diabetes; chronic respiratory diseases; and lung, colon, breast, cervical, liver, and stomach cancers. From 1980 to 2012, on average across all countries, mortality for cardiovascular disease, stomach cancer, and cervical cancer declined, while mortality for diabetes, liver cancer, and female chronic respiratory disease and lung cancer increased. In contrast to the relatively steep cardiovascular and cancer mortality declines observed in high-income countries, mortality for cardiovascular disease and chronic respiratory disease was flat in most low- and middle-income countries, which also experienced increasing breast and colon cancer mortality. These divergent mortality patterns likely reflect differences in timing and magnitude of risk exposures, health care, and policies to counteract the diseases. Improving both the coverage and the accuracy of mortality documentation in populous low- and middle-income countries is a priority, as is the need to rigorously evaluate societal-level interventions. Furthermore, given the complex, chronic, and progressive nature of noncommunicable diseases, policies and programs to prevent and control them need to be multifaceted and long-term, as returns on investment accrue with time.

    Citizen science projects have a long history in ecological studies. The research usefulness of such projects is dependent on applying simple and standardized methods. Here, we conducted a citizen science project that involved more than 3500 Swedish high school students to examine the temperature difference between surface water and the overlying air (T w -T a ) as a proxy for sensible heat flux (Q H ). If Q H is directed upward, corresponding to positive T w -T a , it can enhance CO 2 and CH 4 emissions from inland waters, thereby contributing to increased greenhouse gas concentrations in the atmosphere. The students found mostly negative T w -T a across small ponds, lakes, streams/rivers and the sea shore (i.e. downward Q H ), with T w -T a becoming increasingly negative with increasing T a . Further examination of T w -T a using high-frequency temperature data from inland waters across the globe confirmed that T w -T a is linearly related to T a . Using the longest available high-frequency temperature time series from Lake Erken, Sweden, we found a rapid increase in the occasions of negative T w -T a with increasing annual mean T a since 1989. From these results, we can expect that ongoing and projected global warming will result in increasingly negative T w -T a , thereby reducing CO 2 and CH 4 transfer velocities from inland waters into the atmosphere.

    Facilitative interactions are defined as positive effects of one species on another, but bidirectional feedbacks may be positive, neutral, or negative. Understanding the bidirectional nature of these interactions is a fundamental prerequisite for the assessment of the potential evolutionary consequences of facilitation. In a global study combining observational and experimental approaches, we quantified the impact of the cover and richness of species associated with alpine cushion plants on reproductive traits of the benefactor cushions. We found a decline in cushion seed production with increasing cover of cushion-associated species, indicating that being a benefactor came at an overall cost. The effect of cushion-associated species was negative for flower density and seed set of cushions, but not for fruit set and seed quality. Richness of cushion-associated species had positive effects on seed density and modulated the effects of their abundance on flower density and fruit set, indicating that the costs and benefits of harboring associated species depend on the composition of the plant assemblage. Our study demonstrates 'parasitic' interactions among plants over a wide range of species and environments in alpine systems, and we consider their implications for the possible selective effects of interactions between benefactor and beneficiary species. © 2013 The Authors.

    The rate of DNA synthesis after γ-irradiation was studied either by analysis of the steady-state distribution of daughter [ 3 H]DNA in alkaline sucrose gradients or by direct assay of the amount of [ 3 H]thymidine incorporated into DNA of fibroblasts derived from a normal donor (LCH882) and from Down's syndrome (LCH944), Werner's syndrome (WS1LE) and xeroderma pigmentosum (XP2LE) patients with chromosomal sensitivity to ionizing radiation. Doses of γ-irradiation that markedly inhibited the rate of DNA synthesis in normal human cells caused almost no inhibition of DNA synthesis in the cells from the affected individuals. The radioresistant DNA synthesis in Down's syndrome cells was mainly due to a much lower inhibition of replicon initiation than that in normal cells; these cells were also more resistant to damage that inhibited replicon elongation. Our data suggest that radioresistant DNA synthesis may be an intrinsic feature of all genetic disorders showing increased radiosensitivity in terms of chromosome aberrations. (orig.)

    This study assessed the presence of specific antibodies for coeliac disease in outpatients suffering from eating disorders before and after nutritional intervention. We also evaluated whether those patients should undergo regular screening for coeliac disease. The sample consisted of 154 patients with a mean age of 16.7 years - ranging from one to 19 years of age - suffering from eating disorders. Serology screening for coeliac disease and total immunoglobulin A (IgA) levels was evaluated in the 154 children before the nutritional intervention and in 104 patients after the intervention. The patients consumed an adequate amount of gluten in both phases. Postintervention evaluation revealed that 92 patients (88.5%) achieved a normal body weight, while the remaining 12 (11.5%) became obese. Postprandial abdominal discomfort and pain were resolved. The serology tests were negative in all patients, before and after intervention. None displayed IgA deficiency. To the best of our knowledge, this was the first prospective study where patients underwent a screening serology for coeliac disease before and after nutritional intervention. No indication of the coexistence of eating disorders and coeliac disease was documented, and the patients in our study were unlikely to require regular screening for coeliac disease. ©2015 Foundation Acta Paediatrica.

    Full Text Available Background: Studies have demonstrated the diagnostic accuracy and prognostic value of physical stress echocardiography in coronary artery disease. However, the prediction of mortality and major cardiac events in patients with exercise test positive for myocardial ischemia is limited. Objective: To evaluate the effectiveness of physical stress echocardiography in the prediction of mortality and major cardiac events in patients with exercise test positive for myocardial ischemia. Methods: This is a retrospective cohort in which 866 consecutive patients with exercise test positive for myocardial ischemia, and who underwent physical stress echocardiography were studied. Patients were divided into two groups: with physical stress echocardiography negative (G1 or positive (G2 for myocardial ischemia. The endpoints analyzed were all-cause mortality and major cardiac events, defined as cardiac death and non-fatal acute myocardial infarction. Results: G2 comprised 205 patients (23.7%. During the mean 85.6 ± 15.0-month follow-up, there were 26 deaths, of which six were cardiac deaths, and 25 non-fatal myocardial infarction cases. The independent predictors of mortality were: age, diabetes mellitus, and positive physical stress echocardiography (hazard ratio: 2.69; 95% confidence interval: 1.20 - 6.01; p = 0.016. The independent predictors of major cardiac events were: age, previous coronary artery disease, positive physical stress echocardiography (hazard ratio: 2.75; 95% confidence interval: 1.15 - 6.53; p = 0.022 and absence of a 10% increase in ejection fraction. All-cause mortality and the incidence of major cardiac events were significantly higher in G2 (p < 0. 001 and p = 0.001, respectively. Conclusion: Physical stress echocardiography provides additional prognostic information in patients with exercise test positive for myocardial ischemia.

    High rates of no-shows in outpatient clinics are problematic for revenue and for quality of patient care. Longer lead time to appointment has variably been implicated as a risk factor for no-shows, but the evidence within pediatric clinics is inconclusive. The goal of this study was to estimate no-show rates and test for association between appointment lead time and no-show rates for new and follow-up patients. Analyses included 534 new and 1920 follow-up patients from pulmonology and gastroenterology clinics at a freestanding children's hospital. The overall rate of no-shows was lower for visits scheduled within 0 to 30 days compared with 30 days or more (23% compared with 47%, P < .0001). Patient type significantly modified the association of appointment lead time; the rate of no-shows was higher (30%) among new patients compared with (21%) follow-up patients with appointments scheduled within 30 days (P = .004). For appointments scheduled 30 or more days' lead time, no-show rates were statistically similar for new patients (46%) and follow-up patients (0.48%). Time to appointment is a risk factor associated with no-shows, and further study is needed to identify and implement effective approaches to reduce appointment lead time, especially for new patients in pediatric subspecialties.

    This study aims to determine the association of residual venous obstruction (RVO) with recurrent venous thromboembolism (VTE). A retrospective cohort study was conducted determining if RVO on ultrasonography is associated with recurrent VTE in a Singaporean population. The subjects were identified from the Vascular Diagnostic Laboratory patients' record of Tan Tock Seng Hospital (TTSH), Singapore between 2008 and 2013. All the patients included had RVO after 3 months of anticoagulation. Data such as age, gender, race, thrombus location, etiology, history of malignancy, thrombophilia screen, treatment duration, and follow-up were recorded for analysis. Statistical analysis was performed using Stata/SE 13.1 (StataCorp LLC). The study was approved by the National Healthcare Group Domain Specific Review Board (DSRB), Singapore. Out of the 34 patients who had RVO, 6 (17.6%) developed VTE recurrence. Patients were treated with anticoagulation for a mean time of 24.5 months. The mean follow-up time for VTE recurrence was 25.4 months. Out of the six patients who had VTE recurrence, one had common iliac vein involvement, four had superficial femoral vein and common femoral vein involvement, zero had popliteal vein involvement, and one had calf veins involvement. There was a significant association between thrombophilia ( p  = 0.0195) and malignancy ( p  = 0.020) at inclusion with the risk of recurrent VTE. The presence of RVO after 3 months of anticoagulation is likely to increase the risk of VTE recurrence. Larger studies with RVO are needed to evaluate if there is an increased risk of VTE recurrence in the Asian population.

    A 37 year old Chinese man suffered from coexisting narcolepsy and morbid jealousy which were precipitated by head injury 5 years previously. Fluoxetine 20 mg/day reduced his narcoleptic symptoms and morbid jealousy but not his sleepiness. On defaulting treatment, the patient's symptoms and marital problem recurred. A common central serotonin disturbance might be involved in mediating the sleep disorder and associated psychopathology. PMID:8140016

    Full Text Available Abstract Background Alexithymia is a disturbance associated with psychosomatic disorders, pain syndromes, and a variety of psychiatric disorders. The Affect School (AS based on Tomkins Affect Theory is a therapy focusing on innate affects and their physiological expressions, feelings, emotions and scripts. In this pilot study we tried the AS-intervention method in patients with chronic benign pain. Methods The AS-intervention, with 8 weekly group sessions and 10 individual sessions, was offered to 59 patients with chronic non-malignant pain at a pain rehabilitation clinic in Sweden 2004-2005. Pre and post intervention assessments were done with the Hospital Anxiety and Depression scale (HAD, the Toronto Alexithymia Scale-20 (TAS-20, the Visual Analogue Scale for pain assessment (VAS-pain, the European Quality of Life health barometer (EQoL and the Stress and Crisis Inventory-93 (SCI-93. After the group sessions we used Bergdahl's Questionnaire for assessing changes in interpersonal relations, general well-being and evaluation of AS. Results The AS intervention was completed by 54 out of 59 (92% patients. Significant reductions in total TAS-20 post-test scores (p = 0.0006 as well as TAS-20 DIF and DDF factors (Difficulties Identifying Feelings, and Difficulties Describing Feelings were seen (p = 0.0001, and p = 0.0008 while the EOT factor (Externally Oriented Thinking did not change. Improvements of HAD-depression scores (p = 0.04, EQoL (p = 0.02 and self-assessed changes in relations to others (p Conclusions This pilot study involving 59 patients with chronic benign pain indicates that the alexithymia DIF and DDF, as well as depression, social relations and quality of life may be improved by the Affect School therapeutic intervention.

    Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors were approved by the US Food and Drug Administration (FDA) as cholesterol-lowering therapies for patients with familial hypercholesterolemia or atherosclerotic cardiovascular disease. To estimate the long-term health and economic value of PCSK9 inhibitors for Americans (51 years and older). We conducted simulations using the Future Elderly Model, an established dynamic microsimulation model to project the lifetime outcomes for the US population aged 51 years and older. Health effects estimates and confidence intervals from published meta-analysis studies were used to project changes in life expectancy, quality-adjusted life-years, and lifetime medical spending resulting from the use of PCSK9 inhibitors. We considered two treatment scenarios: 1) current FDA eligibility and 2) an extended eligibility scenario that includes patients with no pre-existing cardiovascular disease but at high risk. We assumed that the price of PCSK9 inhibitors was discounted by 35% in the first 12 years and by 57% thereafter, with gradual uptake of the drug in eligible populations. Use of PCSK9 inhibitors by individuals covered by current FDA approval would extend life expectancy at the age of 51 years by an estimated 1.1 years and would yield a lifetime net value of $5800 per person. If use was extended to those at high risk for cardiovascular disease, PCSK9 inhibitors would generate a lifetime net benefit of $14,100 per person. Expanded access to PCSK9 inhibitors would offer positive long-term net value for patients and the US health care system at the current discounted prices.

    Full Text Available We report a case of acute baclofen poisoning in a 23-year-old female patient, who committed suicide, which led to the development of a deep coma. The electroencephalogram on the first day recorded the phenomenon of “burst suppression”, which was seen as a sign of a dying brain. Subsequent studies have shown positive changes of the electroencephalogram and regression of neurological symptoms. Thus, the phenomenon of “burst suppression” in the depression of consciousness to deep coma and given adequate treatment, can be reversible.

    Purpose: To determine the prevalence of clinically relevant non-inflammatory disease on MRI of the sacroiliac (SI) joints in patients suspected of sacroiliitis. To assess the added value of axial imaging of the pelvis in these patients. Methods: In a retrospective study of 691 patients undergoing MRI of the SI joints from January 2006 to December 2012 for inflammatory back pain the prevalence of sacroiliitis and non-inflammatory disease was recorded. Results: In 285 (41%) patients MRI did not show any abnormal findings. In 36% of patients MRI features of sacroiliitis were present. Spinal degenerative changes were the most common non-inflammatory finding in 305 patients (44.1%) and consisted of disc degeneration in 222 (32%) patients, facet joint arthrosis in 58 (8.4%) patients and disc herniation in 25 (3.6%) patients. Hip joint disease in 44 (6.4%) patients, lumbosacral transitional anomaly in 41 (5.9%) patients, SI joint degenerative changes in 25 (3.6%) patients and diffuse idiopathic skeletal hyperostosis in 24 (3.5%) patients were also common. Osteitis condensans ilii in 17 (2.5%) patients, tumour in 11 (1.6%) patients, fracture in 8 (1.2%) patients, infection in 4 (0.6%) patients and acute spondylolysis in 2 patients (0.3%) were less frequently seen. Conclusion: Our study shows that non-inflammatory disease is more common than true sacroiliitis on MRI of the SI joints in patients with inflammatory type back pain. Axial pulse sequences may demonstrate unexpected findings that remain undetected if only coronal images are obtained. Clinical relevance statement:, MRI of the SI joints may demonstrate conditions that clinically mimic sacroiliitis. Axial imaging of the pelvis may help detect these unexpected findings.

  5. Showing the Unsayable: Participatory Visual Approaches and the Constitution of 'Patient Experience' in Healthcare Quality Improvement.

    2018-06-01

    This article considers the strengths and potential contributions of participatory visual methods for healthcare quality improvement research. It argues that such approaches may enable us to expand our understanding of 'patient experience' and of its potential for generating new knowledge for health systems. In particular, they may open up dimensions of people's engagement with services and treatments which exceed both the declarative nature of responses to questionnaires and the narrative sequencing of self reports gathered through qualitative interviewing. I will suggest that working with such methods may necessitate a more reflexive approach to the constitution of evidence in quality improvement work. To this end, the article will first consider the emerging rationale for the use of visual participatory methods in improvement before outlining the implications of two related approaches-photo-elicitation and PhotoVoice-for the constitution of 'experience'. It will then move to a participatory model for healthcare improvement work, Experience Based Co-Design (EBCD). It will argue that EBCD exemplifies both the strengths and the limitations of adequating visual participatory approaches to quality improvement ends. The article will conclude with a critical reflection on a small photographic study, in which the author participated, and which sought to harness service user perspectives for the design of psychiatric facilities, as a way of considering the potential contribution of visual participatory methods for quality improvement.

    2014-01-01

    Full Text Available Varicocele is one of the most common causes of low semen quality, which is reflected in high percentages of sperm cells with fragmented DNA. While varicocelectomy is usually performed to ameliorate a patient’s fertility, its impact on sperm DNA integrity in the case of subclinical varicocele is poorly documented. In this study, multiple DNA fragmentation analyses (TUNEL, SCD, and SCSA were performed on semen samples from sixty infertile patients with varicocele (15 clinical varicoceles, 19 clinical varicoceles after surgical treatment, 16 subclinical varicoceles, and 10 subclinical varicoceles after surgical treatment. TUNEL, SCD, and SCSA assays all showed substantial sperm DNA fragmentation levels that were comparable between subclinical and clinical varicocele patients. Importantly, varicocelectomy did improve sperm quality in patients with clinical varicocele; however, this was not the case in patients with subclinical varicocele. In summary, although infertile patients with clinical and subclinical varicocele have similar sperm DNA quality, varicocelectomy should only be advised for patients with clinical varicocele.

    Although ischemic electrocardiographic (ECG) changes during dipyridamole or adenosine infusion have been reported as a marker for severe coronary artery disease (CAD), few studies have focused on ST-segment changes with adenosine triphosphate (ATP)-loading myocardial single-photon emission computed tomography (SPECT). Between January 2003 and August 2008, 4650 consecutive patients underwent ATP-loading SPECT. After 1412 patients with left bundle branch block, pacemaker rhythm, or previous coronary revascularization were excluded, 16 out of 3238 patients (0.5%) showed ischemic ST-segment depression during ATP-loading myocardial SPECT. They were aged 67±11 years; 10 were men and 6 women. Of these patients, 8 demonstrated perfusion abnormalities, whereas the remaining 8 showed normal myocardial perfusion imaging. In 6 of the 8 patients with abnormal SPECT, coronary angiography was performed, revealing left main trunk disease in 1 patient, 3-vessel disease in 4, 1-vessel disease with proximal left ascending artery occlusion in 1, and an insignificant lesion in 1. By contrast, no major cardiac event was observed in the 8 patients with normal SPECT during follow-up for an average of 2 years. The prevalence of ischemic ST-segment changes during ATP loading is very rare. However, this finding should be taken into account since almost half of the patients, particularly those with perfusion abnormalities, may have severe CAD which requires coronary revascularization.

    Missed appointments reduce the efficiency of the health care system and negatively impact access to care for all patients. Identifying patients at risk for missing an appointment could help health care systems and providers better target interventions to reduce patient no-shows. Our aim was to develop and test a predictive model that identifies patients that have a high probability of missing their outpatient appointments. Demographic information, appointment characteristics, and attendance history were drawn from the existing data sets from four Veterans Affairs health care facilities within six separate service areas. Past attendance behavior was modeled using an empirical Markov model based on up to 10 previous appointments. Using logistic regression, we developed 24 unique predictive models. We implemented the models and tested an intervention strategy using live reminder calls placed 24, 48, and 72 hours ahead of time. The pilot study targeted 1,754 high-risk patients, whose probability of missing an appointment was predicted to be at least 0.2. Our results indicate that three variables were consistently related to a patient's no-show probability in all 24 models: past attendance behavior, the age of the appointment, and having multiple appointments scheduled on that day. After the intervention was implemented, the no-show rate in the pilot group was reduced from the expected value of 35% to 12.16% (p value < 0.0001). The predictive model accurately identified patients who were more likely to miss their appointments. Applying the model in practice enables clinics to apply more intensive intervention measures to high-risk patients. Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.

    Full Text Available Transient global amnesia was established by Fisher et Adams is 1964 for phenomena characterized by the sudden onset of all types memory loss, retrograde amnesia and the inability to form new  memories and to recall the recent past. The incidence of TGA is 5  to10 people per 100,000 worldwide but the real incidence is unknown because the episodes of memory loss are temporary and many patients don’t go to see a doctor at the time of attack. The triggers of TAG are physical activity, sexual  intercourse, pain, Valsalva maneuver etc. In routine clinical practice  TAG is more important for neurologists. But this problem is also  interesting for therapeutists because TAG could be developed in  patients with arterial hypertension, foramen ovale, mitral valve  prolapse and heart blocks. We present a 57-year-old female with  TAG. She was admitted to the hospital due to hypertensive crisis and an impaired ability to retain new information that started after  physical activity. The diagnosis of TAG was based on information  from attacks witnesses, the sudden onset of anterograde amnesia,  normal cognition of the patient and short duration of attack. Also,  the patient had no features of stroke, acute hypertensive encephalopathy, epilepsy and alcohol blackout. TAG is more typical for females over 50 years, all symptoms start after physical activity and resolve within 24 hours. It is characterized by reversibility of all symptoms and good prognosis of 2 years of follow-up.

    Malnutrition is a common problem among cancer patients, usually occurs due to poor appetite, low food intake, and changes in body metabolism. The aim of this study is to determine the prevalence of malnutrition in patients receiving chemotherapy on an outpatient basis. This cross-sectional study conducted on 300 cancer patients referred to hospital. The prevalence of malnutrition among patients was assessed using the abridged scored patient-generated subjective global assessment (abPG-SGA) standard questionnaire. Moreover, patient's weight and 24 h dietary recall were measured. Descriptive statistics were used to present characteristics of patients and dietary recalls. For revealing the correlation, Spearman correlation was used. The average abPG-SGA score was 7.6 (standard deviation [SD] = 5.4) and 60.7% of patients were malnourished and required nutritional intervention. Patients mean age and mean duration of illness were 54.2 (SD = 14.7(years, 25 months, respectively. The most common complaint of patients included fatigue (51.3%), anorexia (43.3%), and dry mouth (41%). Reduction in food intake in past month was reported by 41.7% of patients. According to the high prevalence of cancers and increasing growth of them in recent years with regard to outpatient treatment development for cancer patients, using the abPG-SGA standard questionnaire by nutritionist or nurses can be effective to detect malnourished patients and reduce complications caused by disease.

    Full Text Available Abstract Background Both thyroid stimulating hormone (TSH and thyroid stimulating antibody (TSAb negative Graves’s disease (GD is extremely rare. Here we present such a patient. Case presentation The patient was a 76-year-old woman who was diagnosed as having schizophrenia forty years ago. She did not show characteristic symptoms for hyperthyroidism, such as swelling of thyroid, exophthalmos, tachycardia and tremor, however, she showed only psychomotor agitation. Serum free triiodothyronine and free thyroxine levels were elevated and TSH level was suppressed, suggesting the existence of hyperthyroidism. However, both the first generation TSH receptor autoantibody (TRAb1 and the thyroid stimulating autoantibody (TSAb were negative. Slightly increased blood flow and swelling was detected by thyroid echography. Thyroid scintigraphy demonstrated diffuse and remarkably elevated uptake of 123I uptake. Finally, we diagnosed her as having GD. She was treated by using methimazole, and hyperthyroidism and her psychiatric symptoms were promptly ameliorated. Discussion We experienced a patient with GD who did not show characteristic symptoms except for psychiatric symptoms, and also showed negativity for both TRAb1 and TSAb. Thyroid autoantibody-negative GD is extremely rare. Thyroid scintigraphy was useful to diagnose such a patient.

    In vitro expanded mesenchymal stromal cells (MSCs) are increasingly used as experimental cellular therapy. However, there have been concerns regarding the safety of their use, particularly with regard to possible oncogenic transformation. MSCs are the hypothesized precursor cells of high-grade osteosarcoma, a tumor with often complex karyotypes occurring mainly in adolescents and young adults. To determine if MSCs from osteosarcoma patients could be predisposed to malignant transformation we cultured MSCs of nine osteosarcoma patients and five healthy donors for an average of 649 days (range 601-679 days). Also, we compared MSCs derived from osteosarcoma patients at diagnosis and from healthy donors using genome wide gene expression profiling. Upon increasing passage, increasing frequencies of binucleate cells were detected, but no increase in proliferation suggestive of malignant transformation occurred in MSCs from either patients or donors. Hematopoietic cell specific Lyn substrate 1 (HLCS1) was differentially expressed (fold change 0.25, P value 0.0005) between MSCs of osteosarcoma patients (n = 14) and healthy donors (n = 9). This study shows that although HCLS1 expression was downregulated in MSCs of osteosarcoma patients and binucleate cells were present in both patient and donor derived MSCs, there was no evidence of neoplastic changes to occur during long-term culture.

    Transient global amnesia (TGA) is known as a disease of benign nature characterized with clinically transient global antegrade amnesia and a variable degree of global retrograde memory impairment, but it usually resolved within 24 hours. The aims of this study are to assess the alterations in regional cerebral blood flow (rCBF) by Tc-99m HMPAO SPECT imaging with statistical parametric mapping (SPM) analysis and to verify the cognitive deficits by neuropsychological test in TGA patients. Twelve patients with TGA and age-matched normal control subjects participated in this study. Tc-99m HMPAO SPECT was performed within 1 to 19 days (mean duration: 7.3:±5.2 days) after the events to measure the rCBF. SPECT images were analyzed using SPM (SPM99) with Matlab 5.3. Seoul Neuropsychological Screening Battery test was also done within 2 to 8 days (mean duration 3.8±2.2 days) for cognitive functions in 8 of 12 patients with TGA. The SPM analysis of SPECT images showed significantly decreased rCBF in the left inferior frontal gyrus (Brodmann area 9), the left supramarginal gyrus (Brodmann area 40), the left postcentral gyrus (Brodmann area 40) and the left precentral gyrus (Brodmann area 4) in patients with TGA (uncorrected p<0.01). Neuropsychological test findings represented that several cognitive functions. such as, verbal memory, visual memory, phonemic fluency and confrontational naming, were impaired in patients with TGA compared with normal control. Additionally, on SPM analysis, we found lesions of hyperperfusion in contralateral cerebral hemisphere. Our study shows perfusion deficits in the left cerebral hemisphere in patients with TGA and several cognitive dysfunctions. And we found after clinical symptoms were completely resolved, the lesions of hypoperfusion were still remained. We found that functional quantitative neuroimaging study and neuropsychological test are useful to understand underlying pathomachanism of TGA

    Patients' high adherence to medication is indispensable for the management of skin diseases including atopic dermatitis. We previously showed poor medication adherence in Japanese dermatological patients. This study was conducted to determine the level of adherence to oral or topical medication in Japanese patients with atopic dermatitis, attempting to characterize the socioeconomic status of those patients with poor adherence. A web questionnaire survey on demographic data as well as adherence level was conducted on patients registered in the monitoring system. Adherence level was assessed with Morisky Medication Adherence Scale-8 (MMAS-8). Among a total of 3096 respondents with dermatological disorders, data of 1327 subjects with atopic dermatitis were extracted and analyzed. More than 80% of subjects felt that both oral and topical medications were safe and efficacious, while less than 60% of them were satisfied with their treatment. Levels of adherence to oral and topical treatments were evaluated with MMAS-8, giving scores of 4.6 and 4.2, respectively. Demographic factors such as gender, marital status, state of employment, alcohol consumption, frequency of hospital visits, and experience of drug effectiveness had a significant impact on the degree of adherence to treatment. Medication adherence level in Japanese subjects with atopic dermatitis was relatively low compared with that of other chronic diseases. Our survey has characterized patients with poor adherence, who are good targets for interventions to maximize potentially limited healthcare resources. Copyright © 2015 Z.

    Internet gaming disorder (IGD) and gambling disorder (GD) share similar clinical characteristics but show different brain functional connectivity patterns. Bupropion is known to be effective for the treatment of patients with IGD and GD. We hypothesized that bupropion may be effective for the treatment of Internet-based gambling disorder (ibGD) and IGD and that the connections between the default mode network (DMN) and cognitive control network (CCN) would be different between ibGD and IGD patients after 12 weeks of bupropion treatment. 16 patients with IGD, 15 patients with ibGD, and 15 healthy subjects were recruited in this study. At baseline and after 12 weeks of bupropion treatment, the clinical symptoms of patients with IGD or ibGD were assessed, and brain activity was evaluated using resting state functional magnetic resonance imaging. After the 12-week bupropion treatment, clinical symptoms, including the severity of IGD or GD, depressive symptoms, attention, and impulsivity improved in both groups. In the IGD group, the functional connectivity (FC) within the posterior DMN as well as the FC between the DMN and the CCN decreased following treatment. Moreover, the FC within the DMN in the IGD group was positively correlated with changes in Young Internet Addiction Scale scores after the bupropion treatment period. In the ibGD group, the FC within the posterior DMN decreased while the FC within the CCN increased after the bupropion treatment period. Moreover, the FC within the CCN in the ibGD group was significantly greater than that in the IGD group. Bupropion was effective in improving clinical symptoms in patients with IGD and ibGD. However, there were differences in the pharmacodynamics between the two groups. After 12 weeks of bupropion treatment, the FC within the DMN as well as between the DMN and CCN decreased in patients with IGD, whereas the FC within the CCN increased in patients with ibGD.

    The aim of this study was to assess the patients' global impression (PGI) after symptom management, as well as the achievement of personalized symptom goals (PSG). The secondary outcome was to assess related factors. Subjects, Materials, and Methods . Advanced cancer patients admitted to palliative care units rated symptom intensity by using the Edmonton Symptom Assessment Score (ESAS) at admission and then after 1 week. For each symptom, patient-reported PGI and PSG, as well as the rate of PSG response, were evaluated. Eight hundred seventy-six patients were taken into consideration for this study. A mean of 1.71-2.16 points was necessary to perceive a bit better improvement of symptom intensity. Most patients had a PSG of ≤3. A statistically significant number of patients achieved their PSG after starting palliative care. Patients with high intensity of ESAS items at admission achieved a more favorable PGI response. In the multivariate analysis, symptom intensity and PSG were the most frequent factors independently associated to a best PGI, whereas high levels of Karnofsky had a lower odd ratio. PSG and PGI seem to be relevant for patients' assessment and decision-making process, translating in terms of therapeutic intervention. Some factors may be implicated in determining the individual target and clinical response.

    The paper looks in detail at patients that were treated at one of the most discussed companies operating in the field of untried stem cell treatments, Beike Biotech of Shenzhen, China. Our data show that patients who had been treated at Beike Biotech view themselves as proactively pursuing treatment choices that are not available in their home countries. These patients typically come from a broad variety of countries: China, the United Kingdom, the United States, South Africa and Australia. Among the patients we interviewed there seemed to be both an awareness of the general risks involved in such experimental treatments and a readiness to accept those risks weighed against the possible benefits. We interpret this evidence as possibly reflecting the emergence of risk-taking patients as 'consumers' of medical options as well as the drive of patients to seek treatment options in the global arena, rather than being hindered by the ethical and regulatory constraints of their home countries. Further, we found that these patients tend to operate in more or less stable networks and groups in which they interact and cooperate closely and develop opinions and assessments of available treatment options for their ailments. These patients also perform a multiple role as patients, research subjects, and research funders because they are required to pay their way into treatment and research activities. This new social dynamics of patienthood has important implications for the ethical governance of stem cell treatments. © 2011 Blackwell Publishing Ltd.

    Full Text Available Abstract Background To compare the efficacy and safety of budesonide/formoterol (Symbicort® with formoterol (Oxis® in the treatment of patients with acute asthma who showed evidence of refractoriness to short-acting β2-agonist therapy. Methods In a 3 hour, randomized, double-blind study, a total of 115 patients with acute asthma (mean FEV1 40% of predicted normal and a refractory response to salbutamol (mean reversibility 2% of predicted normal after inhalation of 400 μg, were randomized to receive either budesonide/formoterol (320/9 μg, 2 inhalations at t = -5 minutes and 2 inhalations at 0 minutes [total dose 1280/36 μg] or formoterol (9 μg, 2 inhalations at t = -5 minutes and 2 inhalations at 0 minutes [total dose 36 μg]. The primary efficacy variable was the average FEV1 from the first intake of study medication to the measurement at 90 minutes. Secondary endpoints included changes in FEV1 at other timepoints and change in respiratory rate at 180 minutes. Treatment success, treatment failure and patient assessment of the effectiveness of the study medication were also measured. Results FEV1 increased after administration of the study medication in both treatment groups. No statistically significant difference between the treatment groups was apparent for the primary outcome variable, or for any of the other efficacy endpoints. There were no statistically significant between-group differences for treatment success, treatment failure or patient assessment of medication effectiveness. Both treatments were well tolerated. Conclusion Budesonide/formoterol and formoterol provided similarly rapid relief of acute bronchoconstriction in patients with asthma who showed evidence of refractoriness to a short-acting β2-agonist.

    This study was designed to evaluate the perioperative nutritional status of patients undergoing surgery for gastrointestinal cancer using Subjective Global Assessment and surgeon behavior on nutritional support. We recruited 100 patients undergoing surgery for gastrointestinal cancer in one university and two state teaching hospitals. Subjective Global Assessment was administered to evaluate preoperative and postoperative nutritional status. Fifty-two patients in the state hospitals (Group 1) and 48 in the university hospital were assessed. Anthropometric and biochemical measurements were performed. Changes in preoperative Subjective Global Assessment scores and scores at the time of discharge and types of nutritional support were compared. Subjective Global Assessment-B was regarded as moderate and Subjective Global Assessment-C as heavy malnutrition. Ten patients had Subjective Global Assessment-B and 29 had Subjective Global Assessment-C malnutrition in Group 1 and nine had Subjective Global Assessment-B and 31 had Subjective Global Assessment-C malnutrition in Group 2 during preoperative assessment. Respective numbers in postoperative assessment were 12 for Subjective Global Assessment-B and 30 for Subjective Global Assessment-C in Group 1 and 14 for Subjective Global Assessment-B and 26 for Subjective Global Assessment-C in Group 2. There was no difference between two groups. Nutritional methods according to Subjective Global Assessment evaluation in pre- and postoperative periods were not different between the groups. This study demonstrated that the malnutrition rate is high among patients scheduled for gastrointestinal cancer surgery and the number of surgeons were inadequate to provide perioperative nutritional support. Both university and state hospitals had similar shortcomings. Subjective Global Assessment is an easy and reliable test and if utilized will be helpful to detect patients requiring nutritional support.

    Microphthalmia and anophthalmia (MA) are congenital eye abnormalities that show an extremely high clinical and genetic complexity. In this study, we evaluated the implementation of whole exome sequencing (WES) for the genetic analysis of MA patients. This approach was used to investigate three unrelated families in which previous single-gene analyses failed to identify the molecular cause. A total of 47 genes previously associated with nonsyndromic MA were included in our panel. WES was performed in one affected patient from each family using the AmpliSeq TM Exome technology and the Ion Proton TM platform. A novel heterozygous OTX2 missense mutation was identified in a patient showing bilateral anophthalmia who inherited the variant from a parent who was a carrier, but showed no sign of the condition. We also describe a new PAX6 missense variant in an autosomal-dominant pedigree affected by mild bilateral microphthalmia showing high intrafamiliar variability, with germline mosaicism determined to be the most plausible molecular cause of the disease. Finally, a heterozygous missense mutation in RBP4 was found to be responsible in an isolated case of bilateral complex microphthalmia. This study highlights that panel-based WES is a reliable and effective strategy for the genetic diagnosis of MA. Furthermore, using this technique, the mutational spectrum of these diseases was broadened, with novel variants identified in each of the OTX2, PAX6, and RBP4 genes. Moreover, we report new cases of reduced penetrance, mosaicism, and variable phenotypic expressivity associated with MA, further demonstrating the heterogeneity of such disorders. © 2017 The Authors.

    Despite the aging population, few studies have documented the treatment of geriatric psoriasis. The purpose of this study is to compare the efficacy, safety, and prescribing patterns of biologics and conventional systemic medications in elderly versus adult psoriasis. All patient visits coded for psoriasis or psoriatic arthritis (ICD-9 696.1 or 696.0) at the Tufts Medical Center General Dermatology Clinic from January 1, 2008, to March 1, 2015 were included in this retrospective cohort study. The outcome measure used was the validated simple-measure for assessing psoriasis activity (S-MAPA), the product of the physician's global assessment and the body surface area. 194 patients who underwent 278 treatment courses were included in the study. 48 patients were included in the elderly cohort (≥ 65 years old) and 146 in the adult cohort (18-64 years old). There was no significant difference in S-MAPA improvement at 12 weeks between the two cohorts when treated with biologics (42.92% improvement in adults, 48.77% in elderly; P=0.498) or conventional systemics (43.96% and 51.82%, respectively; P=0.448). Within the elderly cohort, there was no significant difference in efficacy of biologics versus conventional systemics at any time point. Topical prescription rates were significantly higher in the elderly cohort ( P=0.004) while biologic prescription rates were significantly lower ( P=0.014) despite the same baseline S-MAPA in both age groups. For both biologics and conventional systemics, there was no statistically significant intergroup difference in the rate of adverse events ( P=0.322 for biologics; P=0.581 for conventional systemics) or infection ( P=0.753 for biologics; P=0.828 for conventional systemics). Within the elderly cohort, there was a higher rate of adverse events with conventional systemic treatment than with biologic treatment ( P=0.033). This study provides preliminary evidence to suggest that biologic and conventional systemic therapies are similarly

    The purpose of this study was to evaluate the clinical value of bilateral breast magnetic resonance (MR) imaging (MRI) in patients showing suspicious microcalcifications on mammography and negative ultrasound findings. Fifty patients underwent MRI before stereotactic vacuum-assisted breast biopsy (SVAB). MR findings were classified into five types for interpretation, and types 4 and 5 were considered malignant. SVAB revealed 13 carcinomas and 37 benign lesions. Malignant lesions were more frequently found in cases of positive MRI diagnoses than in negative MRI diagnoses (P < 0.001). Mammography had a sensitivity of 100%, a specificity of 24% and an accuracy of 44%, whereas mammography plus MRI had a sensitivity of 85%, a specificity of 100% and an accuracy of 96%. In the evaluation of mammographically detected microcalcifications, bilateral breast MRI is of good diagnostic value and may alter the indications for SVAB. (orig.)

    Full Text Available ObjectivesThe German socio-demographic estimation scale was developed by Jahn et al. (1 to quickly predict premorbid global cognitive functioning in patients. So far, it has been validated in healthy adults and has shown a good correlation with the full and verbal IQ of the Wechsler Adult Intelligence Scale (WAIS in this group. However, there are no data regarding its use as a bedside test in epilepsy patients.MethodsForty native German speaking adult patients with refractory epilepsy were included. They completed a neuropsychological assessment, including a nine scale short form of the German version of the WAIS-III and the German socio-demographic estimation scale by Jahn et al. (1 during their presurgical diagnostic stay in our center. We calculated means, correlations, and the rate of concordance (range ±5 and ±7.5 IQ score points between these two measures for the whole group, and a subsample of 19 patients with a global cognitive functioning level within 1 SD of the mean (IQ score range 85–115 and who had completed their formal education before epilepsy onset.ResultsThe German demographic estimation scale by Jahn et al. (1 showed a significant mean overestimation of the global cognitive functioning level of eight points in the epilepsy patient sample compared with the short form WAIS-III score. The accuracy within a range of ±5 or ±7.5 IQ score points for each patient was similar to that of the healthy controls reported by Jahn et al.

    A strong relationship exists between employee satisfaction and patients' perceptions of the quality of their care, measured in terms of their intent to return and to recommend the hospital to others. Employee dissatisfaction can negatively affect quality of care and have an adverse effect on patient loyalty and, thus hospital profitability. Therefore, health care marketers should regularly measure employee satisfaction as one way to monitor service quality. Health care marketers must work more closely with their human-resource departments to understand and influence employees' work environment and maintain a high level of job satisfaction. Marketers also should place an increased emphasis on both employee and patient perceptions of satisfaction when developing internal and external strategic marketing plans and formulating future research.

    Although Bacillus Calmette-Guérin (BCG) vaccines against tuberculosis have been available for more than 90 years, their effectiveness has been hindered by variable protective efficacy and a lack of lasting memory responses. One factor contributing to this variability may be the diversity of the BCG strains that are used around the world, in part from genomic changes accumulated during vaccine production and their resulting differences in gene expression. We have compared the genomes and transcriptomes of a global collection of fourteen of the most widely used BCG strains at single base-pair resolution. We have also used quantitative proteomics to identify key differences in expression of proteins across five representative BCG strains of the four tandem duplication (DU) groups. We provide a comprehensive map of single nucleotide polymorphisms (SNPs), copy number variation and insertions and deletions (indels) across fourteen BCG strains. Genome-wide SNP characterization allowed the construction of a new and robust phylogenic genealogy of BCG strains. Transcriptional and proteomic profiling revealed a metabolic remodeling in BCG strains that may be reflected by altered immunogenicity and possibly vaccine efficacy. Together, these integrated-omic data represent the most comprehensive catalogue of genetic variation across a global collection of BCG strains.

    Abstract To evaluate nutritional status in adult patients with acute leukemia (AL) using patient-generated subjective global assessment (PG-SGA) and to investigate the influence of nutritional status on prognosis. We observationally investigated 68 adult patients with newly diagnosed AL who received PG-SGA at the First Hospital of Jilin University between May 2013 and July 2015. Clinical features, chemotherapy regimens, biochemical indexes, body composition, complete remission (CR) rate, minimal residual disease (MRD), survival time, and side-effects of chemotherapy were compared between patients with and without severe malnutrition. Mean PG-SGA scores of the total patients were 6.1 ± 4.0, and 19 of 68 (27.9%) patients had severe malnutrition (PG-SGA score ≥9). Patients with acute myeloid leukemia (AML) had higher scores than those with acute lymphocytic leukemia (ALL; P = .011) and high-risk patients had higher scores regardless of whether they had AML or ALL (AML, P = .012; ALL, P = .043). Univariate analysis showed that severe malnutrition was correlated with age (P = .041), transferrin (P = .042), Karnofsky Performance Status score (P = .006), and C-reactive protein (CRP) (P = .018). Multivariate analysis demonstrated that severe malnutrition was associated with CRP (hazard ratio [HR] = 1.020, 95% confidence interval [CI]: 1.002–1.039, P = .026). No difference was found in CR rate (P = .831) between patients with and without malnutrition, but those who were severely malnourished had higher MRD (P = .048 in AML patients, P = .036 in ALL patients) and more gastrointestinal side-effects (P = .014). Severe malnutrition was also associated with inferior overall survival (HR = 0.243, 95% CI: 0.063–0.945, P = .041) but not with event-free survival (HR = 0.808, 95% CI: 0.338–1.934, P = .663). Severe malnutrition defined by PG-SGA in adult patients with de novo AL may result in poor outcome

    Parkinson's disease (PD) is a surprisingly heterogeneous neurodegenerative disorder. It is well established that different subtypes of PD present with different clinical courses and prognoses. However, the neural mechanism underlying these disparate presentations is uncertain. Here we used resting-state fMRI (rs-fMRI) and the regional homogeneity (ReHo) method to determine neural activity patterns in the two main clinical subgroups of PD (akinetic-rigid and tremor-dominant). Compared with healthy controls, akinetic-rigid (AR) subjects had increased ReHo mainly in right amygdala, left putamen, bilateral angular gyrus, bilateral medial prefrontal cortex (MPFC), and decreased ReHo in left post cingulate gyrus/precuneus (PCC/PCu) and bilateral thalamus. In contrast, tremor-dominant (TD) patients showed higher ReHo mostly in bilateral angular gyrus, left PCC, cerebellum_crus1, and cerebellum_6, while ReHo was decreased in right putamen, primary sensory cortex (S1), vermis_3, and cerebellum_4_5. These results indicate that AR and TD subgroups both represent altered spontaneous neural activity in default-mode regions and striatum, and AR subjects exhibit more changed neural activity in the mesolimbic cortex (amygdala) but TD in the cerebellar regions. Of note, direct comparison of the two subgroups revealed a distinct ReHo pattern primarily located in the striatal-thalamo-cortical (STC) and cerebello-thalamo-cortical (CTC) loops. Overall, our findings highlight the involvement of default mode network (DMN) and STC circuit both in AR and TD subtypes, but also underscore the importance of integrating mesolimbic-striatal and CTC loops in understanding neural systems of akinesia and rigidity, as well as resting tremor in PD. This study provides improved understanding of the pathophysiological models of different subtypes of PD. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Transient global amnesia (TGA) is a memory disorder characterized by an episode of antegrade amnesia and bewilderment which persists for several hours. We analyzed brain perfusion SPECT findings and clinical outcome of patients who suffered from TGA. From September 2005 to August 2007, 12 patients underwent Tc-99m ECD brain perfusion SPECT for neuroimaging of TGA. All patients also underwent MRI and MRA including DWI (MRI). Among them, 10 patients who could be chased more than 6 months were included in this study. Their average age was 60.74.0 yrs (M: F = 2: 8) and the average duration of amnesia was 4.42.2 hrs (1 hr ∼ 7 hrs). Duration from episode of amnesia to SPECT was 4.32.4 days (1∼9 days). Precipitating factors could be identified in 6 patients: emotional stress 3, hair dyeing 1, taking a nap 1 and angioplasty 1. SPECT and MRI was visually assessed, No cerebral perfusion defect was observed on SPECT in 3 patients and their clinical outcome was all good. Among 7 patients who had cerebral perfusion defects on SPECT, 3 patients had good clinical outcome, while others did not: one had hypercholesterolemia, another had depression, and 2 patients with cerebral perfusion defects at both temporoparetal cortex was later diagnosed as early Alzheimer's disease (AD) and mild cognitive impairment (MCI). MRI was negative in 6 patients and 3 of them had excellent clinical outcome while other 3 were diagnosed as hypercholesterolemia, early AD and MCI. Among 4 patients with positive MRI, 3 showed good clinical outcome and their MRI showed lesions at medial temporal cortex and/or vertebral artery. One patient with microcalcification at left putamen was diagnosed to have depression.

    To explore perceptions of privacy and dignity for sexual relationships in a Forensic mental health hospital. The role of nurses in forensic mental health hospitals is frequently complicated by opposing expectations of therapeutic relationships and maintaining security. What can result is an over-emphasis on risk reduction by controlling patient behaviour, which can extend to patient intimacy and sexual relationships. An exploratory, qualitative approach. Individual interviews were conducted with 12 nurses and 10 patients in a forensic mental health hospital. Thematic data analysis was undertaken to identify the main themes. The need for a private and dignified place for patient intimacy was one major theme to emerge from this research from both nurse and patient participants and is the focus of this article. A disparity is reported between the level of support reported by nurse participants with the experience of the patient participants. Sexual intimacy and sexual relationships are important components of normal human behaviour. Institutional rules and rule adherence create barriers for patients, forcing their intimacy and sexual relationships into secrecy. There is a need for further research to consider the benefits and risks of patient intimacy and sexual relationships for long-term patients in forensic mental health settings. Patients in forensic hospitals are sexually active and seek support from nurses. Nurses are in an ideal role to recognise the important part they can play in supporting the intimacy and sexual relationship needs of patients. Strategies to assist in developing confidence in responding to normal human behaviour is a matter of priority. © 2015 John Wiley & Sons Ltd.

    Angelman syndrome (AS) is a rare neurodevelopmental disorder that is characterised by severe global developmental delays, ataxia, loss of speech, epilepsy, sleep disorders, and a happy disposition. There is currently no cure for AS, though several pharmaceutical companies are anticipating drug trials for new therapies to treat AS. The Foundation for Angelman Therapeutics (FAST) Australia therefore identified a need for a global AS patient registry to identify patients for recruitment for clinical trials.The Global AS Registry was deployed in September 2016 utilising the Rare Disease Registry Framework, an open-source tool that enables the efficient creation and management of patient registries. The Global AS Registry is web-based and allows parents and guardians worldwide to register, provide informed consent, and enter data on individuals with AS. 286 patients have registered in the first 8 months since deployment.We demonstrate the successful deployment of the first patient-driven global registry for AS. The data generated from the Global AS Registry will be crucial in identifying patients suitable for clinical trials and in informing research that will identify treatments for AS, and ultimately improve the lives of individuals and their families living with AS.

    Full Text Available Studies on cognition in multiple system atrophy (MSA patients are limited.A total of 110 MSA patients were evaluated using Addenbrooke's Cognitive Examination-Revised (ACE-R, Frontal Assessment Battery (FAB, Frontal Behavioral Inventory (FBI, and Unified MSA Rating Scale (UMSARS tests. Fifty-five age-, sex-, education- and domicile-matched healthy controls were recruited to perform the FAB and ACE-R scales.Approximately 32.7% of the patients had global cognitive deficits with the most impaired domain being verbal fluency and visuospatial ability (26.4%, followed by memory (24.5%, language (20% and orientation/attention (20% based on a cut-off score of ACE-R ≤ 70. A total of 41.6% of the patients had frontal lobe dysfunction, with inhibitory control (60.9% as the most impaired domain based on a cut-off score of FAB ≤14. Most patients (57.2% showed moderate frontal behavior changes (FBI score 4-15, with incontinence (64.5% as the most impaired domain. The binary logistic regression model revealed that an education level < 9 years (OR:13.312, 95% CI:2.931-60.469, P = 0.001 and UMSARS ≥ 40 (OR: 2.444, 95%CI: 1.002-5.962, P< 0.049 were potential determinants of abnormal ACE-R, while MSA-C (OR: 4.326, 95%CI: 1.631-11.477, P = 0.003, an education level < 9 years (OR:2.809 95% CI:1.060-7.444, P = 0.038 and UMSARS ≥ 40 (OR:5.396, 95%CI: 2.103-13.846, P < 0.0001 were potential determinants of abnormal FAB.Cognitive impairment is common in Chinese MSA patients. MSA-C patients with low education levels and severe motor symptoms are likely to experience frontal lobe dysfunction, while MSA patients with low education levels and severe motor symptoms are likely to experience global cognitive deficits. These findings strongly suggest that cognitive impairment should not be an exclusion criterion for the diagnosis of MSA.

    Cancer patients frequently experience malnutrition. Cancer and cancer therapy effects nutritional status through alterations in the metabolic system and reduction in food intake. In the present study, fifty seven cancer patients were selected as subjects from the oncology ward of Cachar Cancer Hospital and Research Centre, Silchar, India. Evaluation of nutritional status of cancer patients during treatment was carried out by scored Patient-Generated Subjective Global Assessment (PG-SGA). The findings of PG-SGA showed that 15.8% (9) were well nourished, 31.6% (18) were moderately or suspected of being malnourished and 52.6% (30) were severely malnourished. The prevalence of malnutrition was highest in lip/oral (33.33%) cancer patients. The study showed that the prevalence of malnutrition (84.2%) was high in cancer patients during treatment.

    2015-11-01

    Full Text Available Global Health 2035, the report of The Lancet Commission on Investing in Health, laid out a bold, highly ambitious framework for making rapid progress in improving global public health outcomes. It showed that with the right health investments, the international community could achieve a “grand convergence” in global health—a reduction in avertable infectious, maternal, and child deaths down to universally low levels—within a generation. Rwanda’s success in rapidly reducing such deaths over the last 20 years shows that convergence is feasible. Binagwaho and Scott have argued that 5 lessons from this success are the importance of equity, quality health services, evidence-informed policy, intersectoral collaboration, and effective collaboration between countries and multilateral agencies. This article re-examines these lessons through the lens of the Global Health 2035 report to analyze how the experience in Rwanda might be generalized for other countries to making progress towards achieving a grand convergence.

  8. Hip Fractures: What Information Does the Evidence Show That Patients and Families Need to Decrease 30-Day Readmission?

    2015-01-01

    The current bundled payment reimbursement from the Centers for Medicare & Medicaid Services will not cover the additional cost of hospital readmission for the same diagnosis, and patients with hip fractures have one of the highest cost-saving opportunities when compared with other admission reasons. Common reasons for readmission to the hospital after hip fracture include pneumonia, dehydration, and mobility issues. The learning modalities including visual, aural, read/write, and kinesthetic were used to make recommendations on how the education can be incorporated into the instruction of patients with hip fractures and their families. These learning techniques can be used to develop education to decrease possibility of 30-day readmission after hip fracture. Nurses must focus their education to meet the needs of each individual patient, adapting to different types of adult learners to increase the health literacy of patients with hip fractures and their families.

    Full Text Available Cancer treatment for elderly patients is often complicated by poor physical condition, impaired functioning and comorbidities. Patient reported health related quality of life (HRQOL can contribute to decisions about treatment goals and supportive therapy. Knowledge about factors influencing HRQOL is therefore needed for the development of supportive measures and care pathways. An exploratory secondary data analysis on 518 assessments of the European Organisation for Research and Treatment of Cancer (EORTC core questionnaire (EORTC QLQ-C30 and the elderly module (EORTC QLQ-ELD14 was performed to identify factors predictive for global HRQOL. Preliminary simple and multivariable regression analyses were conducted resulting in a final model comprising sociodemographic and disease specific variables and scales of the QLQ-C30 and QLQ-ELD14. Age, sex and disease related variables explained only part of the variance of global HRQOL (adjusted R2 = 0.203. In the final model (adjusted R2 = 0.504 fatigue, social function, burden of illness and joint stiffness showed possible influence on global HRQOL. Fatigue, social function and burden of illness seem to have the largest impact on global HRQOL of elderly cancer patients. Further prospective studies should examine these domains. Actionable symptoms should be given special attention to initiate targeted supportive measures aiming to maximize HRQOL of older cancer patients.

    2008-07-01

    Memory deficits have been reported in schizophrenia and bipolar disorder. However, the precise impact of semantic memory deficits on word comprehension, particularly across grammatical categories, has not been adequately investigated in these disorders. Furthermore, previous studies examining semantic memory have predominantly been designed so that most healthy controls perform at ceiling, questioning the validity of observed differences between patient and control groups. A new word definition task examined word comprehension across grammatical categories, i.e. nouns, verbs and adjectives, and was designed to overcome the ceiling effect. It was administered to 32 schizophrenia patients, 28 bipolar disorder patients and 32 matched healthy controls. Schizophrenia patients had a global impairment on the task but bipolar patients were only impaired on a recognition memory component. Word comprehension, however, across grammatical categories was comparable across groups.

    Platinum agents are essential for treating gynecological malignancies, particularly ovarian cancer. However, multiple carboplatin doses may cause hypersensitivity reactions (HSRs). Carboplatin desensitization prevents life-threatening HSRs and promotes the successful completion of planned chemotherapy. Since January 2010, carboplatin desensitization was performed at our institution. Solutions with 1/1000, 1/100, and 1/10 dilutions of carboplatin and an undiluted solution were prepared in 250 mL of 5% glucose. Each solution was administered as a 1-h intravenous infusion (4-step 4-h protocol). This retrospective analysis was approved by the institutional review board. From January 2010 to December 2013, 20 patients with gynecological malignancies (median age 62 years, range 43-74 years) received desensitization treatment. The International Federation of Gynecology and Obstetrics stages at presentation were I, II, III, and IV in 1, 1, 15, 13 patients, respectively. During first-line and second-line treatments, 3 and 17 patients, respectively, experienced carboplatin-induced HSRs. The median carboplatin cycle number was 11 (range 2-16). In the first desensitization cycle, 17 (85%) patients completed treatment without adverse events, 2 experienced Grade 1 HSRs but completed treatment, and 1 experienced Grade 3 HSR and discontinued treatment. The first desensitization cycle completion rate was 95%. Of 83 desensitization cycles administered, 79 (95.2%) were completed. No treatment-related deaths occurred. Most patients completed the planned chemotherapy. Our protocol could be conducted safely with shorter duration and simpler procedures than previous protocols. Carboplatin desensitization seems beneficial for patients with a history of carboplatin-induced HSRs; however, the risk of HSR recurrence still remains. Desensitization should therefore be performed only by well-trained staff.

    Psoriasis is one of the most frequently occurring chronic inflammatory skin diseases. There are some specialized regions of the body that are considered difficult to treat. Secukinumab is a human monoclonal immunoglobulin G antibody that blocks the interleukin 17A ligand and has been shown to be highly efficacious in treating moderate-to-severe psoriasis. We studied two Greek patients, one with scalp psoriasis and the other with palmoplantar psoriasis, both resistant to treatment. Patients were treated with secukinumab and efficacy and safety were recorded. The patient with severe, refractory palmoplantar psoriasis achieved complete clearance at the end of the 4-week treatment period with secukinumab. The patient with moderate to severe, chronic scalp psoriasis was successfully treated with secukinumab, obtaining complete clearance of symptoms and remission of disease after approximately 16 weeks. In both cases clinical response was maintained through week 52. Secukinumab has been shown to be highly efficacious in the treatment of psoriasis of specific anatomical sites with an acceptable safety profile.

    Urinary tract infections (UTI) are a major cause of morbidity, affecting at least four million women worldwide, 65-75% of these infections are caused by Uropathogenic Escherichia coli (UPEC) (Foxman, 2010) [1]. Repertoire of virulence factors carried by UPEC provides the ability to precede urinary tract and additionally they provoke pro-inflammatory responses (Cirl et al., 2008; Verma et al., 2016) [2], [3]. In context to UPEC infected UTI patients, the levels of pro-inflammatory cytokine IL-1β and enzymatic antioxidant nitric oxide (NO) have not been reported worldwide till date, including India. In this data article, we report for the first time the levels of IL-1β and nitric oxide in the plasma of UPEC infected UTI patients. Data includes a profile of pro-inflammatory cytokine IL-1β and NO in the plasma of the confirmed UPEC infected UTI patients ( N  = 30) versus healthy controls ( N  = 40) from the present pilot study. The levels of IL-1β in plasma were significantly higher ( p  UTI patients (60.29 ± 1.1 μM) as compared to healthy controls (106.3 ± 8.75 μM).

    For the first time in Bulgaria, a deletion/duplication screening was performed on a group of 84 unrelated Duchenne/Becker muscular dystrophy patients, and the breakpoint distribution in the dystrophin gene was analyzed. Intragenic deletions were detected in 67.8% of patients, and intragenic duplications in 2.4%. A peculiar distribution of deletion breakpoints was found. Only 13.2% of the deletion breakpoints fell in the {open_quotes}classical{close_quotes} hot spot in intron 44, whereas the majority (> 54%) were located within the segment encompassing introns 45-51, which includes intron 50, the richest in breakpoints (16%) in the Bulgarian sample. Comparison with data from Greece and Turkey points at the probable existence of a deletion hot spot within intron 50, which might be a characteristic of populations of the Balkan region. 17 refs., 2 figs.

    This paper looks at some aspect of globalisation. After a discussion on its definition, the first part highlights historical evolution of globalisation in its major components (trade flows, foreign direct investments, portfolio movements and migration). The evidence shows that (1) globalisation its not new; (2) it is not irreversible; (3) the new elements in the last phase of globalisation are the low international mobility of labour, the changes in trade policy, the relevance in financial ca...

  19. Efficacy of muscle exercise in patients with muscular dystrophy: a systematic review showing a missed opportunity to improve outcomes.

    Full Text Available BACKGROUND: Although muscular dystrophy causes muscle weakness and muscle loss, the role of exercise in the management of this disease remains controversial. OBJECTIVE: The purpose of this systematic review is to evaluate the role of exercise interventions on muscle strength in patients with muscular dystrophy. METHODS: We performed systematic electronic searches in Medline, Embase, Web of Science, Scopus and Pedro as well as a list of reference literature. We included trials assessing muscle exercise in patients with muscular dystrophy. Two reviewers independently abstracted data and appraised risk of bias. RESULTS: We identified five small (two controlled and three randomized clinical trials comprising 242 patients and two ongoing randomized controlled trials. We were able to perform two meta-analyses. We found an absence of evidence for a difference in muscle strength (MD 4.18, 95% CIs - 2.03 to 10.39; p = 0.91 and in endurance (MD -0.53, 95% CIs -1.11 to 0.05; p = 0.26. In both, the direction of effects favored muscle exercise. CONCLUSIONS: The first included trial about the efficacy of muscular exercise was published in 1978. Even though some benefits of muscle exercise were consistently reported across studies, the benefits might be due to the small size of studies and other biases. Detrimental effects are still possible. After several decades of research, doctors cannot give advice and patients are, thus, denied basic information. A multi-center randomized trial investigating the strength of muscles, fatigue, and functional limitations is needed.

    People with neuropsychiatric disorders such as schizophrenia often display deficits in spatial working memory and attention. Evaluating working memory and attention in schizophrenia patients is usually based on traditional tasks and the interviewer's judgment. We developed a simple Spatial Working Memory and Attention Test on Paired Symbols (SWAPS). It takes only several minutes to complete, comprising 101 trials for each subject. In this study, we tested 72 schizophrenia patients and 188 healthy volunteers in China. In a healthy control group with ages ranging from 12 to 60, the efficiency score (accuracy divided by reaction time) reached a peak in the 20-27 age range and then declined with increasing age. Importantly, schizophrenia patients failed to display this developmental trend in the same age range and adults had significant deficits compared to the control group. Our data suggests that this simple Spatial Working Memory and Attention Test on Paired Symbols can be a useful tool for studies of spatial working memory and attention in neuropsychiatric disorders.

    We present a case in which chemoradiation therapy was effective in a geriatric patient with Stage IV anal canal cancer. The patient is an 81-year-old woman who complained of proctorrhagia and anal pain. She was referred to us by her family doctor who suspected rectal cancer. Tumors as large as 6.5 cm in diameter mainly on the right side of the rectum as well as 2 palpable enlarged lymph nodes on the right inguinal area, were found during the initial physical examination. Squamous cell carcinoma was elevated to 16 ng/mL. A CT scan revealed that irregularly shaped masses as large as 7 cm in diameter were externally exposed on the right side of the rectum along with enlarged lymph nodes on the right inguinal area and metastasis at S7 lesion in the liver. Squamous cell carcinoma was diagnosed from biopsy results. Due to her age, the chemotherapy regimen was S-1+CDDP with radiation therapy and 4-port irradiation (50.4 Gy) of the primary tumor, interior of the pelvis, and inguinal lymph nodes. Partial response was observed upon completion of treatment, and complete response was obtained after 6 months. She is currently an outpatient taking S-1: 60 mg/day orally. There is no indication of cancer recurrence after 1 year and 3 months, and she continues to visit an outpatient clinic for regular follow-ups. These results demonstrate the effectiveness of chemoradiation therapy for geriatric patients with Stage IV anal canal cancer.

    Full Text Available Subjective measurements of cognition have seldom been used in schizophrenia. This is mainly due to the assumption that such measurements lack sensitivity in a disorder characterized by poor insight. We investigated the capacity of BRIEF-A (Behavior Rating Inventory of Executive Function - Adult Version: a self-administered, ecological questionnaire to identify executive deficits in adults with schizophrenia. The global score and each domain-specific score was significantly lower in patients than in healthy controls. BRIEF-A could be a useful complement to objective measurements, providing a subjective assessment of everyday consequences of executive dysfunction in patients with schizophrenia.

    Saliva plays a key role in maintaining oral homeostasis, function, and health. The prevalence of xerostomia and its consequences are rising due to the increasing aging population, the effects of some systemic diseases, medical management, and commonly-prescribed medications that reduce saliva production. When salivary function is diminished, patients are at a greater risk of developing caries, discomfort in wearing dentures, and opportunistic diseases, such as candidiasis. The psychosocial aspects of xerostomia can range from a mild effect on self-rated oral health to frustration, embarrassment, unhappiness, or substantial disruptions in quality of life. This article reviews the clinical features, diagnosis, and prevalence of dry mouth, as well as its treatment strategies. © 2014 Wiley Publishing Asia Pty Ltd.

    Background and purpose: Reported associations between risk of radiation-induced normal tissue injury and single nucleotide polymorphisms (SNPs) in TGFB1, encoding the pro-fibrotic cytokine transforming growth factor-beta 1 (TGF-β1), remain controversial. To overcome publication bias, the international Radiogenomics Consortium collected and analysed individual patient level data from both published and unpublished studies. Materials and methods: TGFB1 SNP rs1800469 c.-1347T>C (previously known as C-509T) genotype, treatment-related data, and clinically-assessed fibrosis (measured at least 2 years after therapy) were available in 2782 participants from 11 cohorts. All received adjuvant breast radiotherapy. Associations between late fibrosis or overall toxicity, reported by STAT (Standardised Total Average Toxicity) score, and rs1800469 genotype were assessed. Results: No statistically significant associations between either fibrosis or overall toxicity and rs1800469 genotype were observed with univariate or multivariate regression analysis. The multivariate odds ratio (OR), obtained from meta-analysis, for an increase in late fibrosis grade with each additional rare allele of rs1800469 was 0.98 (95% Confidence Interval (CI) 0.85–1.11). This CI is sufficiently narrow to rule out any clinically relevant effect on toxicity risk in carriers vs. non-carriers with a high probability. Conclusion: This meta-analysis has not confirmed previous reports of association between fibrosis or overall toxicity and rs1800469 genotype in breast cancer patients. It has demonstrated successful collaboration within the Radiogenomics Consortium.

    The use of complementary and alternative medicine has increased over the past decade. The aim of this study was to evaluate whether homeopathy influenced global health status and subjective wellbeing when used as an adjunct to conventional cancer therapy. In this pragmatic randomized controlled trial, 410 patients, who were treated by standard anti-neoplastic therapy, were randomized to receive or not receive classical homeopathic adjunctive therapy in addition to standard therapy. The study took place at the Medical University Vienna, Department of Medicine I, Clinical Division of Oncology. The main outcome measures were global health status and subjective wellbeing as assessed by the patients. At each of three visits (one baseline, two follow-up visits), patients filled in two different questionnaires. 373 patients yielded at least one of three measurements. The improvement of global health status between visits 1 and 3 was significantly stronger in the homeopathy group by 7.7 (95% CI 2.3-13.0, p=0.005) when compared with the control group. A significant group difference was also observed with respect to subjective wellbeing by 14.7 (95% CI 8.5-21.0, p<0.001) in favor of the homeopathic as compared with the control group. Control patients showed a significant improvement only in subjective wellbeing between their first and third visits. Results suggest that the global health status and subjective wellbeing of cancer patients improve significantly when adjunct classical homeopathic treatment is administered in addition to conventional therapy.

    Many Gram-negative bacteria, unlike Gram-positive, are directly lysed by complement. Ureaplasma can cause septic arthritis and meningitis in immunocompromised individuals and induce premature birth. Ureaplasma has no cell wall, cannot be Gram-stain classified and its serum susceptibility is unknown. Survival of Ureaplasma serovars (SV) 1, 3, 6 and 14 (collectively Ureaplasma parvum) were measured following incubation with normal or immunoglobulin-deficient patient serum (relative to heat-inactivated controls). Blocking monoclonal anti-C1q antibody and depletion of calcium, immunoglobulins, or lectins were used to determine the complement pathway responsible for killing. Eighty-three percent of normal sera killed SV1, 67% killed SV6 and 25% killed SV14; greater killing correlating to strong immunoblot identification of anti-Ureaplasma antibodies; killing was abrogated following ProteinA removal of IgG1. All normal sera killed SV3 in a C1q-dependent fashion, irrespective of immunoblot identification of anti-Ureaplasma antibodies; SV3 killing was unaffected by total IgG removal by ProteinG, where complement activity was retained. Only one of four common variable immunodeficient (CVID) patient sera failed to kill SV3, despite profound IgM and IgG deficiency for all; however, killing of SV3 and SV1 was restored with therapeutic intravenous immunoglobulin therapy. Only the classical complement pathway mediated Ureaplasma-cidal activity, sometimes in the absence of observable immunoblot reactive bands. Copyright © 2011 Elsevier GmbH. All rights reserved.

    Fibromyalgia (FM) has been understudied in the elderly population, a group with particular vulnerabilities to pain, reduced mobility, and sleep disruption. To characterize FM symptoms and treatments in a cohort of older subjects examined over time to determine the extent to which current, community-based treatment for older FM patients is in accord with published guidelines, and effective in reducing symptoms. A longitudinal, observational study of 51 subjects with FM (range 55-95 years) and 81 control subjects (58-95 years) performed at Banner Sun Health Research Institute in Sun City, AZ, USA. Serial history and examination data were obtained over a 6-year period. FM data included medical history, medications, physical examination, tender point examination, neuropsychological testing, sleep and pain ratings, the Physical Function Subscale of the Fibromyalgia Impact Questionnaire, and other standardized scales to evaluate depression and other psychiatric symptoms, and cognitive and functional impairment. Pain and stiffness that interfered with physical activity, sleep, and mood were reported by 80 % or more of subjects. Over time, pain involved an increasing number of body areas. Over half of subjects were treated with NSAIDs, one-quarter with opioids, and one-quarter with estrogen. Few were treated with dual-acting antidepressants or pregabalin. In this cohort of elders with suboptimally treated FM, substantial persistence of symptoms was seen over time. In general, recommended treatments were either not used or not tolerated. Age-appropriate treatments as well as education of primary care providers are needed to improve treatment of FM in the older population.

    2013-01-01

    Background Digital forms of direct-to-consumer pharmaceutical marketing (eDTCA) have globalized in an era of free and open information exchange. Yet, the unregulated expansion of eDTCA has resulted in unaddressed global public health threats. Specifically, illicit online pharmacies are engaged in the sale of purportedly safe, legitimate product that may in fact be counterfeit or substandard. These cybercriminal actors exploit available eDTCA mediums over the Internet to market their suspect products globally. Despite these risks, a detailed assessment of the public health, patient safety, and cybersecurity threats and governance mechanisms to address them has not been conducted. Discussion Illicit online pharmacies represent a significant global public health and patient safety risk. Existing governance mechanisms are insufficient and include lack of adequate adoption in national regulation, ineffective voluntary governance mechanisms, and uneven global law enforcement efforts that have allowed proliferation of these cybercriminals on the web. In order to effectively address this multistakeholder threat, inclusive global governance strategies that engage the information technology, law enforcement and public health sectors should be established. Summary Effective global “eHealth Governance” focused on cybercrime is needed in order to effectively combat illicit online pharmacies. This includes building upon existing Internet governance structures and coordinating partnership between the UN Office of Drugs and Crime that leads the global fight against transnational organized crime and the Internet Governance Forum that is shaping the future of Internet governance. Through a UNODC-IGF governance mechanism, investigation, detection and coordination of activities against illicit online pharmacies and their misuse of eDTCA can commence. PMID:24131576

    Patients with a porencephalic cyst frequently develop intractable temporal lobe epilepsy (TLE). We report a surgically-treated male patient with intractable mesial TLE (mTLE) secondary to a porencephalic cyst. Although magnetic resonance imaging showed no hippocampal abnormalities, long-term video-electrocorticography revealed seizure onset discharges in the hippocampus. Temporal lobectomy brought an end to the patient's seizures. Hippocampal sclerosis was histopathologically confirmed (dual pathology). Careful evaluation of hippocampal epileptogenicity is required, and temporal lobectomy, which is less invasive than hemispherectomy, can be a treatment of choice for patients with mTLE secondary to a porencephalic cyst.

    Background Previous resting-state functional connectivity studies in patients with anorexia nervosa used independent component analysis or seed-based connectivity analysis to probe specific brain networks. Instead, modelling the entire brain as a complex network allows determination of graph-theoretical metrics, which describe global and local properties of how brain networks are organized and how they interact. Methods To determine differences in network properties between female patients with acute anorexia nervosa and pairwise matched healthy controls, we used resting-state fMRI and computed well-established global and local graph metrics across a range of network densities. Results Our analyses included 35 patients and 35 controls. We found that the global functional network structure in patients with anorexia nervosa is characterized by increases in both characteristic path length (longer average routes between nodes) and assortativity (more nodes with a similar connectedness link together). Accordingly, we found locally decreased connectivity strength and increased path length in the posterior insula and thalamus. Limitations The present results may be limited to the methods applied during preprocessing and network construction. Conclusion We demonstrated anorexia nervosa–related changes in the network configuration for, to our knowledge, the first time using resting-state fMRI and graph-theoretical measures. Our findings revealed an altered global brain network architecture accompanied by local degradations indicating wide-scale disturbance in information flow across brain networks in patients with acute anorexia nervosa. Reduced local network efficiency in the thalamus and posterior insula may reflect a mechanism that helps explain the impaired integration of visuospatial and homeostatic signals in patients with this disorder, which is thought to be linked to abnormal representations of body size and hunger.

    To determine changes of visual-field (VF) global indices after cataract surgery and the factors associated with the effect of cataracts on those indices in primary open-angle glaucoma (POAG) patients. A retrospective chart review of 60 POAG patients who had undergone phacoemulsification and intraocular lens insertion was conducted. All of the patients were evaluated with standard automated perimetry (SAP; 30-2 Swedish interactive threshold algorithm; Carl Zeiss Meditec Inc.) before and after surgery. VF global indices before surgery were compared with those after surgery. The best-corrected visual acuity, intraocular pressure (IOP), number of glaucoma medications before surgery, mean total deviation (TD) values, mean pattern deviation (PD) value, and mean TD-PD value were also compared with the corresponding postoperative values. Additionally, postoperative peak IOP and mean IOP were evaluated. Univariate and multivariate logistic regression analyses were performed to identify the factors associated with the effect of cataract on global indices. Mean deviation (MD) after cataract surgery was significantly improved compared with the preoperative MD. Pattern standard deviation (PSD) and visual-field index (VFI) after surgery were similar to those before surgery. Also, mean TD and mean TD-PD were significantly improved after surgery. The posterior subcapsular cataract (PSC) type showed greater MD changes than did the non-PSC type in both the univariate and multivariate logistic regression analyses. In the univariate logistic regression analysis, the preoperative TD-PD value and type of cataract were associated with MD change. However, in the multivariate logistic regression analysis, type of cataract was the only associated factor. None of the other factors was associated with MD change. MD was significantly affected by cataracts, whereas PSD and VFI were not. Most notably, the PSC type showed better MD improvement compared with the non-PSC type after cataract surgery

    Full Text Available IgG4-related disease is a novel disease entity characterized by diffuse lymphoplasmacytic infiltration rich in IgG4-positive plasma cells and fibrosis into multiple organs. There is still controversy over whether some thyroid diseases are actually IgG4-related disease. The objective of this study was to elucidate the clinicopathological features of Graves' disease with diffuse lymphoplasmacytic infiltration in the thyroid.Among 1,484 Graves' disease patients who underwent thyroidectomy, we examined their histopathological findings including the degree of lymphoplasmacytic and fibrotic infiltration and levels of IgG4-positive plasma cells in the thyroid. Their clinical pictures were defined by laboratory and ultrasonographic evaluation.A total of 11 patients (0.74% showed diffuse lymphoplasmacytic infiltration in the stroma of the thyroid gland. Meanwhile, other patients showed variable lymphoid infiltration ranging from absent to focally dense but no aggregation of plasma cells in the thyroid gland. Based on the diagnostic criteria of IgG4-related disease, 5 of the 11 subjects had specifically increased levels of IgG4-positive plasma cells in the thyroid. Fibrotic infiltration was present in only 1 patient developing hypothyroidism after anti-thyroid drug treatment for 4 years, but not in the other 10 patients with persistent hyperthyroidism. Obliterative phlebitis was not identified in any of the 11 subjects. Thyroid ultrasound examination showed 1 patient developing hypothyroidism who had diffuse hypoechogenicity, but the other hyperthyroid patients had a coarse echo texture.In our study, Graves' disease patients with persistent hyperthyroidism who had diffuse lymphoplasmacytic infiltration rich in IgG4-positive plasma cells in the thyroid showed no concomitant fibrosis or obliterative phlebitis.

    Background Tens of millions of patients worldwide suffer disabling injuries or death every year due to unsafe medical care. Nonetheless, there is a scarcity of research evidence on how to tackle this global health priority. The shortage of trained researchers is a major limitation, particularly in developing and transitional countries. Objectives As a first step to strengthen capacity in this area, the authors developed a set of internationally agreed core competencies for patient safety research worldwide. Methods A multistage process involved developing an initial framework, reviewing the existing literature relating to competencies in patient safety research, conducting a series of consultations with potential end users and international experts in the field from over 35 countries and finally convening a global consensus conference. Results An initial draft list of competencies was grouped into three themes: patient safety, research methods and knowledge translation. The competencies were considered by the WHO Patient Safety task force, by potential end users in developing and transitional countries and by international experts in the field to be relevant, comprehensive, clear, easily adaptable to local contexts and useful for training patient safety researchers internationally. Conclusions Reducing patient harm worldwide will require long-term sustained efforts to build capacity to enable practical research that addresses local problems and improves patient safety. The first edition of Competencies for Patient Safety Researchers is proposed by WHO Patient Safety as a foundation for strengthening research capacity by guiding the development of training programmes for researchers in the area of patient safety, particularly in developing and transitional countries, where such research is urgently needed.

    Background Resident interest in global health care training is growing and has been shown to have a positive effect on participants' clinical skills and cultural competency. In addition, it is associated with career choices in primary care, public health, and in the service of underserved populations. The purpose of this study was to explore, through reflective practice, how participation in a formal global health training program influences pediatric residents' perspectives when caring for diverse patient populations. Methods Thirteen pediatric and combined-program residents enrolled in a year-long Global Health Scholars Program at Cincinnati Children's Hospital Medical Center during the 2007–2008 academic year. Educational interventions included a written curriculum, a lecture series, one-on-one mentoring sessions, an experience abroad, and reflective journaling assignments. The American Society for Tropical Medicine and Hygiene global health competencies were used as an a priori coding framework to qualitatively analyze the reflective journal entries of the residents. Results Four themes emerged from the coded journal passages from all 13 residents: (1) the burden of global disease, as a heightened awareness of the diseases that affect humans worldwide; (2) immigrant/underserved health, reflected in a desire to apply lessons learned abroad at home to provide more culturally effective care to immigrant patients in the United States; (3) parenting, or observed parental, longing to assure that their children receive health care; and (4) humanitarianism, expressed as the desire to volunteer in future humanitarian health efforts in the United States and abroad. Conclusions Our findings suggest that participating in a global health training program helped residents begin to acquire competence in the American Society for Tropical Medicine and Hygiene competency domains. Such training also may strengthen residents' acquisition of professional skills, including the

    Neil Lunt and Russel Mannion provide an overview of the current state of the medical tourism literature and propose areas for future research in health policy and management. The authors also identify the main unanswered questions in this field ranging from the real size of the medical tourism market to the particular health profiles of transnational patients. In addition, they highlight unexplored areas of research from health economics, ethics, policy and management perspectives. To this very insightful editorial I would add the international trade perspective. While globalization has permeated labor and capital, services such as healthcare are still highly regulated by governments, constrained to regional or national borders and protected by organized interests. Heterogeneity of healthcare regulations and lack of cross-country reciprocity agreements act as barriers to the development of more widespread and dynamic medical tourism markets. To picture these barriers to transnational health services I use evidence from North America, identifying different "pull and push factors" for medical tourist in this region, discussing how economic integration and healthcare reform might shift the incentives to utilize healthcare abroad.

    Patients with chronic hepatitis B virus (HBV) infection who develop antiviral resistance lose benefits of therapy and may be predisposed to further resistance. Entecavir (ETV) resistance (ETVr) results from HBV reverse transcriptase substitutions at positions T184, S202, or M250, which emerge in the presence of lamivudine (LVD) resistance substitutions M204I/V +/- L180M. Here, we summarize results from comprehensive resistance monitoring of patients with HBV who were continuously treated with ETV for up to 5 years. Monitoring included genotypic analysis of isolates from all patients at baseline and when HBV DNA was detectable by polymerase chain reaction (> or = 300 copies/mL) from Years 1 through 5. In addition, genotyping was performed on isolates from patients experiencing virologic breakthrough (> or = 1 log(10) rise in HBV DNA). In vitro phenotypic ETV susceptibility was determined for virologic breakthrough isolates, and for HBV containing novel substitutions emerging during treatment. The results over 5 years of therapy showed that in nucleoside-naïve patients, the cumulative probability of genotypic ETVr and genotypic ETVr associated with virologic breakthrough was 1.2% and 0.8%, respectively. In contrast, a reduced barrier to resistance was observed in LVD-refractory patients, as the LVD resistance substitutions, a partial requirement for ETVr, preexist, resulting in a 5-year cumulative probability of genotypic ETVr and genotypic ETVr associated with breakthrough of 51% and 43%, respectively. Importantly, only four patients who achieved < 300 copies/mL HBV DNA subsequently developed ETVr. Long-term monitoring showed low rates of resistance in nucleoside-naïve patients during 5 years of ETV therapy, corresponding with potent viral suppression and a high genetic barrier to resistance. These findings support ETV as a primary therapy that enables prolonged treatment with potent viral suppression and minimal resistance.

    Observations performed in a subset of subjects treated with finasteride (an inhibitor of the enzyme 5α-reductase) for male pattern hair loss seem to indicate that sexual dysfunction as well as anxious/depressive symptomatology may occur at the end of the treatment and continue after discontinuation. A possible hypothesis to explain depression symptoms after finasteride treatment might be impairment in the levels of neuroactive steroids. Therefore, neuroactive steroid levels were evaluated in paired plasma and cerebrospinal fluid samples obtained from male patients who received finasteride for the treatment of androgenic alopecia and who, after drug discontinuation, still show long-term sexual side effects as well as anxious/depressive symptomatology. The levels of neuroactive steroids were evaluated by liquid chromatography-tandem mass spectrometry in three postfinasteride patients and compared to those of five healthy controls. Neuroactive steroid levels in plasma and cerebrospinal fluid of postfinasteride patients and healthy controls. At the examination, the three postfinasteride patients reported muscular stiffness, cramps, tremors, and chronic fatigue in the absence of clinical evidence of any muscular disorder or strength reduction. Severity and frequency of the anxious/depressive symptoms were quite variable; overall, all the subjects had a fairly complex and constant neuropsychiatric pattern. Assessment of neuroactive steroid levels in patients showed some interindividual differences. However, the most important finding was the comparison of their neuroactive steroid levels with those of healthy controls. Indeed, decreased levels of tetrahydroprogesterone, isopregnanolone and dihydrotestosterone and increased levels of testosterone and 17β-estradiol were reported in cerebrospinal fluid of postfinasteride patients. Moreover, decreased levels of dihydroprogesterone and increased levels of 5α-androstane-3α,17β-diol and 17β-estradiol were observed in

    The purpose of this prospective multi-institutional study was to evaluate the nutritional status of patients undergoing radiotherapy (RT) for treatment of head and neck, lung, or gastrointestinal cancer. A total of 1,000 patients were enrolled in this study at seven different hospitals in Seoul, Korea between October 2009 and May 2010. The nutritional status of patients after receiving 3 weeks of RT was evaluated using subjective global assessment (SGA). The nutritional status of each patient was rated as well nourished (A), moderately malnourished (B), or severely malnourished (C). The mean age of patients in this study was 59.4 {+-} 11.9 years, and the male to female ratio was 7:3. According to the SGA results, 60.8%, 34.5%, and 4.7% of patients were classified as A, B, or C, respectively. The following criteria were significantly associated with malnutrition (SGA B or C; p < 0.001): loss of subcutaneous fat or muscle wasting (odds ratio [OR], 11.473); increased metabolic demand/stress (OR, 8.688); ankle, sacral edema, or ascites (OR, 3.234); and weight loss 5% (OR, 2.299). SGA was applied successfully to assess the nutritional status of most patients. The prevalence of malnutrition in a radiation oncology department was 39.2%. The results of this study serve as a basis for implementation of nutrition intervention to patients being treated at radiation oncology departments.

    Heart failure (HF) patients show gray and white matter changes in multiple brain sites, including autonomic and motor coordination areas. It is unclear whether the changes represent acute or chronic tissue pathology, a distinction necessary for understanding pathological processes that can be resolved with diffusion tensor imaging (DTI)-based mean diffusivity (MD) procedures. We collected four DTI series from 16 HF (age 55.1 ± 7.8 years, 12 male) and 26 control (49.7 ± 10.8 years, 17 male) subjects with a 3.0-Tesla magnetic resonance imaging scanner. MD maps were realigned, averaged, normalized, and smoothed. Global and regional MD values from autonomic and motor coordination sites were calculated by using normalized MD maps and brain masks; group MD values and whole-brain smoothed MD maps were compared by analysis of covariance (covariates; age and gender). Global brain MD (HF vs. controls, units × 10(-6) mm(2) /sec, 1103.8 ± 76.6 vs. 1035.9 ± 69.4, P = 0.038) and regional autonomic and motor control site values (left insula, 1,085.4 ± 95.7 vs. 975.7 ± 65.4, P = 0.001; right insula, 1,050.2 ± 100.6 vs. 965.7 ± 58.4, P = 0.004; left hypothalamus, 1,419.6 ± 165.2 vs. 1,234.9 ± 136.3, P = 0.002; right hypothalamus, 1,446.5 ± 178.8 vs. 1,273.3 ± 136.9, P = 0.004; left cerebellar cortex, 889.1 ± 81.9 vs. 796.6 ± 46.8, P right cerebellar cortex, 797.8 ± 50.8 vs. 750.3 ± 27.5, P = 0.001; cerebellar deep nuclei, 1,236.1 ± 193.8 vs. 1,071.7 ± 107.1, P = 0.002) were significantly higher in HF vs. control subjects, indicating chronic tissue changes. Whole-brain comparisons showed increased MD values in HF subjects, including limbic, basal-ganglia, thalamic, solitary tract nucleus, frontal, and cerebellar regions. Brain injury occurs in autonomic and motor control areas, which may contribute to deficient function in HF patients. The chronic tissue changes likely

    ABSTRACT Background and aim Assessment of therapeutic response is important for monitoring the prognosis and to take decision for cessation of nucleoside analogues therapy in chronic hepatitis B patients. In addition to serum alanine aminotransferase (ALT), hepatitis B virus (HBV) deoxyribonucleic acid (DNA) load and HBeAg status, identification of molecular markers associated with host immune response would be essential to assess therapeutic response. In this regard the current study was performed with the aim to detect expression of platelet endothelial cell adhesion molecule (PECAM)-I gene in peripheral blood monocytes (PBMCs) of treated chronic hepatitis B patients and also to correlate expression of this gene with serum HBV DNA load and serum ALT levels. Materials and methods The study analyzed 60 chronic hepatitis B (CHB) patients, including 30 untreated and 30 nucleoside analogs treated and 10 healthy controls. PECAM-1 gene expression/ transcripts were detected by conventional RT-PCR. Results The expression PECAM-1 mRNA in the PBMCs of CHB patients was significantly higher in untreated (3.17 ± 0.75) than the treated patients (1.64 ± 0.29) (p Tabassum S, Munshi SU, Hossain M, Imam A.

    In developing countries like Bangladesh, delayed presentation for disorders of sex development (DSD) is common, and provides some special problems for management. There remains significant controversy about appropriate sex assignment in this group. We aimed, therefore, to assess gender identity (GI) in 50 consecutive patients with DSD presenting to a referral centre in Chittagong, Bangladesh, and correlate it with Prader score, to see if the latter could be used to predict GI. A cross-sectional, case-control study of 50 consecutive children with DSD and 50 children with vascular anomalies was conducted in the Pediatric Surgical Clinic, Chittagong Medical College and Hospital. After informed consent, patients and controls provided oral answers to a GI questionnaire and had a detailed history and physical examination. Sex-typed activities were assessed by observations of a structured toy play and the child's selection of a toy to keep. Both patients and parents then completed the Child Game Participation Questionnaire. There were no differences in age (2-16 years, mean 8.74) between controls and DSD patients (11 46, XX DSD, 32 46, XY DSD, 4 MGD, 3 ovo-testicular DSD). Fifteen of the DSD patients (30 %) came from consanguineous marriages and only 2 of the control patients had consanguinity of their parents. For the 13-question GI interview, there was no overall difference between DSD cases and controls. For the 46, XX DSD subgroup, there was a significantly higher score (11.1 ± 7.1) compared with control girls (4.5 ± 4.7) (p gender-related behaviour correlated with Prader score for DSD patients (r = 0.61) (p gender-role behaviour should be assessed routinely in DSD patients presenting after the neonatal period, so that sex assignment is in accordance with behaviour. Prader scores showed a good correlation with GI and gender role behaviour.

    Implementation of the Charter to protect patients' rights is an important criterion to achieve patient-centered approach and receive financial support from the Global Fund. Our study aims to explore the knowledge of tuberculosis (TB) patients about their rights and responsibilities at the Chest Disease Unit of the Bahawal Victoria Hospital, Bahawalpur, Pakistan. This was a qualitative study. The data from purposefully selected TB patients was collected by in-depth interviews. Eligibility criteria included confirmed diagnosis of TB and enrollment in the TB program. A pilot tested interview protocol was based upon the objectives of the study, and was used uniformly in each interview to maintain the consistency. The sample size was limited by applying the saturation criteria. All interviews were audiotaped and transcribed verbatim. Inductive thematic content analysis was applied to analyze the data and draw conclusions. Out of the total 16 patients, four were female, and seven were illiterate. Eight patients were known cases of multi-drug resistant TB. Analysis of the data yielded seven themes; tuberculosis care services, moral support and stigmatization, dignity and privacy, complaints, fear of losing job, information sharing and compliance to the treatment plan, and contribution to eradicate TB. First five represented the rights section while latter two were related to the responsibilities section of the Charter. Discriminatory access to TB care services and the right to privacy were two major concerns identified in this study. However, the respondents recognized their responsibilities as a TB patient. To ensure uninterrupted investment from the Global Fund, there is a need to implement fair TB care policies which support human rights-based approach.

    Full Text Available Objective This study aims to evaluate “in vivo” the integrity of the normal-appearing spinal cord (NASC in patients with multiple sclerosis (MS compared to controls, using diffusion tensor MR imaging. Methods We studied 32 patients with MS and 17 without any neurologic disorder. Fractional anisotropy (FA, axial diffusivity (AD, radial diffusivity (RD and mean diffusivity (MD were calculated within regions of interest at C2 and C7 levels in the four columns of the spinal cord. Results At C2, FA value was decreased in MS patients. Besides, RD value was higher in MS than in controls. At C7, MD values were increased in MS. Conclusion The NASC in the right column of the cervical spinal cord showed abnormal FA, RD and MD values, which is possibly related to demyelination, since the FA abnormality was related to the RD and not to the AD.

    To determine differences between peripheral blood mononuclear cells and the plasma metabolites in patients with impaired fasting glucose or type 2 diabetes and healthy controls. In all, 65 nononobese patients (aged 30-70 years) with impaired fasting glucose or type 2 diabetes and 65 nonobese sex-matched healthy controls were included, and fasting peripheral blood mononuclear cell and plasma metabolomes were profiled. The diabetic or impaired fasting glucose patients showed higher circulating and peripheral blood mononuclear cell lipoprotein phospholipase A 2 activities, high-sensitivity C-reactive protein and tumour necrosis factor-α than controls. Compared with controls, impaired fasting glucose or diabetic subjects showed increases in 11 peripheral blood mononuclear cell metabolites: six amino acids (valine, leucine, methionine, phenylalanine, tyrosine and tryptophan), l-pyroglutamic acid, two fatty acid amides containing palmitic amide and oleamide and two lysophosphatidylcholines. In impaired fasting glucose or diabetic patients, peripheral blood mononuclear cell lipoprotein phospholipase A 2 positively associated with peripheral blood mononuclear cell lysophosphatidylcholines and circulating inflammatory markers, including tumour necrosis factor-α, high-sensitivity C-reactive protein and lipoprotein phospholipase A 2 activities. In plasma metabolites between patients and healthy controls, we observed significant increases in only three amino acids (proline, valine and leucine) and decreases in only five lysophosphatidylcholines. This study demonstrates significant differences in the peripheral blood mononuclear cell metabolome in patients with impaired fasting glucose or diabetes compared with healthy controls. These differences were greater than those observed in the plasma metabolome. These data suggest peripheral blood mononuclear cells as a useful tool to better understand the inflammatory pathophysiology of diabetes.

    Michael Bernhard Fischer

    2015-05-01

    Full Text Available Background: Common variable immunodeficiency (CVID is the most common clinically severe primary immunodeficiency and comprises a heterogeneous group of patients with recurrent severe bacterial infections due to the failure to produce IgG antibodies after exposure to infectious agents and immunization. Diagnostic recommendations for antibody failure include assessment of isoagglutinins. We have readdressed this four decades old but still accepted recommendation with up to date methodology.Methods: Anti-A/B IgM- and IgG-antibodies were measured by Diamed-ID Micro Typing, surface plasmon resonance (SPR using the Biacore® device and flow cytometry.Results: When Diamed-ID Micro Typing was used, CVID patients (n=34 showed IgG- and IgM-isoagglutinins that were comparable to healthy volunteers (n=28, while all XLA patients (n=8 had none. Anti-A/B IgM-antibodies were present in more than 2/3 of the CVID patients and showed binding kinetics comparable to anti-A/B IgM-antibodies from healthy individuals. A correlation could be found in CVID patients between levels of anti-A/B IgM-antibodies and levels of serum IgM and PnP-IgM-antibodies. In contrast in CVID patients as a group ABO antibodies were significantly decreased when assessed by SPR, which correlated with levels of switched memory, non-switched memory and naïve B cells, but all CVID patients had low/undetectable anti-A/B IgG-antibodies.Conclusion: These results indicate that conventional isoagglutinin assessment and assessment of anti-A/B IgM antibodies are not suited for the diagnosis of impaired antibody production in CVID. Examination of anti-A/B IgG antibodies by SPR provides a useful method for the diagnosis of IgG antibody failure in all CVID patients studied, thus indicating an important additional rationale to start immunoglobulin replacement therapy early in these patients, before post-infectious sequelae develop.

    This study investigated alterations in regional cerebral blood flow (rCBF) in patients with transient global amnesia (TGA) using statistical parametric mapping 99 (SPM99). Noninvasive rCBF measurements using 99mTc-ethyl cysteinate dimer (ECD) SPECT were performed on 8 patients with TGA and 17 age matched controls. The relative rCBF maps in patients with TGA and controls were compared. In patients with TGA, significantly decreased rCBF was found along the left superior temporal extending to left parietal region of the brain and left thalamus. There were areas of increased rCBF in the right temporal, right frontal region and right thalamus. We could demonstrate decreased perfusion in left cerebral hemisphere and increased perfusion in right cerebral hemisphere in patients with TGA using SPM99. The reciprocal change of rCBF between right and left cerebral hemisphere in patients with TGA might suggest that imbalanced neuronal activity between the bilateral hemispheres may be important role in the pathogenesis of the TGA. For quantitative SPECT analysis in TGA patients, we recommend SPM99 rather than the ROI method because of its definitive advantages.

    BACKGROUND: Countries around the world are currently aiming to improve patient safety by means of the Institute for Healthcare Improvement global trigger tool (GTT), which is considered a valid tool for evaluating and measuring patient safety within organisations. So far, only few data....... RESULTS: Only 31% of adverse events (AE) were identified by both teams, and further differences in categorisation of identical events was found. Moderate interrater agreement (κ=0.45) between teams gave rise to different conclusions on the patient safety process when monitoring using SPC charts. The Bland......-Altman plot suggests little systematic error but large random error. CONCLUSIONS: Review teams may identify different AE and reach different conclusions on the safety process when using the GTT on identical charts. Tracking true change in the safety level is difficult due to measurement error of the GTT...

    Full Text Available Bile acids may be involved in the regulation of food intake and energy metabolism. The aim of the study was to investigate the association of plasma bile acids with body mass index (BMI and the possible involvement of circulating bile acids in the modulation of physical activity and eating behavior. Blood was obtained in a group of hospitalized patients with normal weight (BMI 18.5-25 kg/m2, underweight (anorexia nervosa, BMI 50 kg/m2, n=14-15/group and plasma bile acid concentrations assessed. Physical activity and plasma bile acids were measured in a group of patients with anorexia nervosa (BMI 14.6±0.3 kg/m2, n=43. Lastly, in a population of obese patients (BMI 48.5±0.9 kg/m2, n=85, psychometric parameters related to disordered eating and plasma bile acids were assessed. Plasma bile acids showed a positive correlation with BMI (r=0.26, p=0.03 in the population of patients with broad range of BMI (9-85 kg/m2, n=74. No associations were observed between plasma bile acids and different parameters of physical activity in anorexic patients (p>0.05. Plasma bile acids were negatively correlated with cognitive restraint of eating (r=-0.30, p=0.008, while no associations were observed with other psychometric eating behavior-related parameters (p>0.05 in obese patients. In conclusion, these data may point towards a role of bile acids in the regulation of body weight. Since plasma bile acids are negatively correlated with the cognitive restraint of eating in obese patients, this may represent a compensatory adaptation to prevent further overeating.

    Several studies have demonstrated the crucial role of complement activation in the pathogenesis of ANCA-associated vasculitis. We aimed to assess the association between baseline serum C3 (sC3) levels and long-term outcomes in patients with renal vasculitis. This retrospective study included 111 patients with renal vasculitis from three hospitals who underwent a renal biopsy between 1997 and 2014. Serum levels of C3 were measured at the onset and the study population was divided into three tertiles according to sC3 concentrations (tertile 1 128 mg/dl). Patients with lower sC3 (tertile 1) were compared with those having higher levels of sC3 (tertile 2 and tertile 3). Histological, clinical, and laboratory data were recorded for analysis. The primary end point was the composite of end-stage renal disease (ESRD) and death from any cause. Lower sC3 levels were associated with a higher need for dialysis and lower response rate to treatment (p = 0.04 and p = 0.007, respectively). Renal and global survival at 1 and 5 years was 53 and 46 % in patients with lower sC3 (tertile 1) compared with 72 and 65 % in patients with higher sC3 (upper two tertiles) (p = 0.04). In a multivariate Cox-regression model, when adjusted by renal function and histopatholologic categories, lower sC3 remained as an independent predictor of ESRD and death (HR, 1.9; 95 % CI, 1.1 to 3.4; p = 0.02). Baseline serum C3 levels have an independent prognostic value in predicting long-term renal and global survival in patients with renal vasculitis.

    To investigate effects of punctal occlusion on global tear protein levels in patients with dry eye. In this prospective, longitudinal, single-center study, nonabsorbable punctal plugs were inserted bilaterally into the lower punctum of 30 patients with moderate dry eye. Dry eye symptoms, fluorescein corneal staining, Schirmer I test, tear film break-up time, and safety were assessed in the more severely affected eye. Tear proteins at weeks 1 and 3 were quantified by iTRAQ relative to baseline preocclusion levels. Of 29 patients who completed the study, 23 (mean age 49.8 years) had sufficient tear samples for analysis. After 3 weeks, punctal occlusion significantly upregulated tear proteins, including glutathione synthase (mean of 1.6-fold, P = 0.01) and interleukin-1 receptor antagonist (1.7-fold, P = 0.032) and downregulated cholinergic receptor (neuronal) alpha-7 (0.79-fold, P = 0.039) and lymphocyte cytosolic protein-1 (0.66-fold, P = 0.012). Clustering analysis of global tear proteins revealed two clear profile changes; the first group of patients (cluster 1, n = 10) had a reduction in the inflammatory proteins (e.g., S100A8) and rise in lacrimal proteins supporting the ocular surface (e.g., lysozyme), whereas the second group (cluster 2, n = 13) had an increase in inflammatory proteins and a decrease in lacrimal proteins. Logistic regression analysis revealed that cluster 1 patients had significantly (P = 0.006) lower Schirmer scores at baseline (mean [standard deviation]: 4.3 [4.3] mm) than cluster 2 (6.8 [2.6] mm). Punctal plugs produced a beneficial pattern of tear protein change in patients with relatively low Schirmer scores within 3 weeks of punctal occlusion. Copyright © 2017 The Authors.

    To investigate the prevalence of malnutrition in patients with inflammatory bowel disease (IBD) by subjective global assessment (SGA) and the effects of oral nutritional support on the clinical parameters, consumption of energy, macronutrients and fiber intake in the Study and Control groups, prospectively. A total of 38 (28 Male; 10 Female) hospitalized patients with moderate or severe IBD (13 with Crohn's disease (CD); 25 with Ulcerative colitis (UC)) were included. At stage 1, the disease severity, clinical symptoms and, signs, food consumption and nutritional status by using subjective global assessment (SGA) were recorded. At stage 2, the patients were blindly randomized into a Study Group and Controls. In the Study Group, a standard enteral product was added into the regulated hospital diets, but for the Controls, deficits were regulated by only hospital diets for 3 weeks. the independent variables were the group, the disease and its activity, age, Body body mass index (BMI), weight loss history, the hospitalization period; the dependent variables were SGA, bowel movements, change in nutritional status, disease severity, clinical findings, and also consumption of macronutrients. Prevalance of malnutrition (SGA-B or SGA-C) for all the patients was 92.1% at the beginning and 71.1% at the end of study. Improvements in disease activity score for the patients with UC were statistically significant in both the Study Group and the Controls (p=0.006 for the Study Group and p=0.001 for the Controls, respectively). Macronutrients, total and water soluble fiber consumption levels improved, with statistically significant differences for all the groups. The prevalence of malnutrition is a major problem in patients with IBD. Not only the regulation of hospital food, but also enteral nutritional support, improved their levels of malnutrition, as well as their energy, macronutrients, and fiber consumption, and SGA is an easy method for nutritional monitoring.

    Full Text Available The goal of this study was to provide insight into the mechanism by which bariatric surgical procedures led to weight loss and improvement or resolution of diabetes. Global biochemical profiling was used to evaluate changes occurring in nondiabetic and type 2 diabetic (T2D patients experiencing either less extreme sleeve gastrectomy or a full gastric bypass. We were able to identify changes in metabolism that were affected by standard preoperation liquid weight loss diet as well as by bariatric surgery itself. Preoperation weight-loss diet was associated with a strong lipid metabolism signature largely related to the consumption of adipose reserves for energy production. Glucose usage shift away from glycolytic pyruvate production toward pentose phosphate pathway, via glucose-6-phosphate, appeared to be shared across all patients regardless of T2D status or bariatric surgery procedure. Our results suggested that bariatric surgery might promote antioxidant defense and insulin sensitivity through both increased heme synthesis and HO activity or expression. Changes in histidine and its metabolites following surgery might be an indication of altered gut microbiome ecology or liver function. This initial study provided broad understanding of how metabolism changed globally in morbidly obese nondiabetic and T2D patients following weight-loss surgery.

    Heart failure (HF) is currently classified according to left ventricular ejection fraction (LVEF); however, the prognostic value of LVEF is controversial. Myocardial strain is a prognostic factor independently of LVEF. The authors sought to evaluate the prognostic value of global longitudinal strain (GLS) in patients with HF. GLS was measured in 4,172 consecutive patients with acute HF. Patients were categorized as either HF with reduced (LVEF 12.6%), moderately (8.1% < GLS <12.5%), or severely (GLS ≤8.0%) reduced strain. The primary endpoint was 5-year all-cause mortality. Mean GLS was 10.8%, and mean LVEF was 40%. Overall, 1,740 (40.4%) patients had died at 5 years. Patients with reduced ejection fraction had slightly higher mortality than those with midrange or preserved ejection fraction (41%, 38%, and 39%, respectively; log-rank p = 0.031), whereas patients with reduced strain had significantly higher mortality (severely reduced GLS, 49%; moderately reduced GLS, 38%; mildly reduced GLS, 34%; log-rank p < 0.001). In multivariable analysis, each 1% increase in GLS was associated with a 5% decreased risk for mortality (p < 0.001). Patients with moderate (hazard ratio: 1.31; 95% confidence interval: 1.13 to 1.53) and severe GLS reductions (hazard ratio: 1.61; 95% confidence interval: 1.36 to 1.91) had higher mortality, but LVEF was not associated with mortality. In patients with acute HF, GLS has greater prognostic value than LVEF. Therefore, the authors suggest that GLS should be considered as the standard measurement in all patients with HF. This new concept needs validation in further studies. Copyright © 2018 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.

    Alterations in global DNA methylation have been associated with oxidative stress (OS). Since chronic obstructive pulmonary disease (COPD) is characterized by increased oxidative stress we aimed to evaluate the levels of global DNA methylation in this patient group. We assessed methylcytosine (mCyt) levels in DNA from blood collected in 43 COPD patients (29 with mild and 14 with moderate disease) and 43 age- and sex-matched healthy controls. DNA methylation was significantly lower in COPD patients vs. controls (4.20 ± 0.18% mCyt vs. 4.29 ± 0.18% mCyt, p = 0.02). Furthermore, DNA methylation in COPD patients with moderate disease was significantly lower than that in patients with mild disease (4.14 ± 0.15% mCyt vs. 4.23 ± 0.19% mCyt, p COPD (crude OR = 0.06, 95% CI 0.00 to 0.67, p = 0.023). This relationship remained significant after adjusting for several confounders (OR 0.03, 95% CI 0.00 to 0.67; p = 0.028). Receiver operating characteristics (ROC) curve analysis demonstrated the area under the curve of mCyt was 0.646, with 46.6% sensitivity and 79.1% specificity for presence of COPD. There were no significant correlations between methylation and OS indices. The presence and severity of COPD is associated with progressively lower DNA methylation in blood. However, this epigenetic alteration seems independent of oxidative stress. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Obstructive sleep apnea (OSA) patients show brain structural injury and functional deficits in autonomic, affective, and cognitive regulatory sites, as revealed by mean diffusivity (MD) and other imaging procedures. The time course and nature of gray and white matter injury can be revealed in more detail with mean kurtosis (MK) procedures, which can differentiate acute from chronic injury, and better show extent of damage over MD procedures. Our objective was to examine global and regional MK changes in newly diagnosed OSA, relative to control subjects. Two diffusion kurtosis image series were collected from 22 recently-diagnosed, treatment-naïve OSA and 26 control subjects using a 3.0-Tesla MRI scanner. MK maps were generated, normalized to a common space, smoothed, and compared voxel-by-voxel between groups using analysis of covariance (covariates; age, sex). No age or sex differences appeared, but body mass index, sleep, neuropsychologic, and cognitive scores significantly differed between groups. MK values were significantly increased globally in OSA over controls, and in multiple localized sites, including the basal forebrain, extending to the hypothalamus, hippocampus, thalamus, insular cortices, basal ganglia, limbic regions, cerebellar areas, parietal cortices, ventral temporal lobe, ventrolateral medulla, and midline pons. Multiple sites, including the insular cortices, ventrolateral medulla, and midline pons showed more injury over previously identified damage with MD procedures, with damage often lateralized. Global mean kurtosis values are significantly increased in obstructive sleep apnea (OSA), suggesting acute tissue injury, and these changes are principally localized in critical sites mediating deficient functions in the condition. The mechanisms for injury likely include altered perfusion and hypoxemia-induced processes, leading to acute tissue changes in recently diagnosed OSA. © 2016 Associated Professional Sleep Societies, LLC.

    Beta-endorphin and adrenocorticotropic hormone (ACTH) were determined simultaneously in the plasma using a radioimmunological procedure. It was found that in patients showing imbalances within the hypothalamus-pituitary-adrenal system (Addison's disease, Cushing's Syndrome, Nelson's Syndrome) as well as elevated levels of beta-endorphin the values of ACHT invariably were also increased. The behaviour of the plasma levels of beta-endorphin and ACTH before, during and subsequent to hypophyseal surgery gives evidence to prove the close link between the two hormones. Tests performed to examine the function of the corticotropin releasing factor (CRF) both in healthy volunteers and patients suffering from endocrinological disorders likewise pointed to a parallel behaviour pattern of the two hormones in their responding or failure to respond to stimulation. The fact that a significant correlation was established between all measured values of beta-endorphin and ACTH is further evidence in confirmation of a parallel release of these two hormones in man.

    The Scored Patient-Generated Subjective Global Assessment (PG-SGA) is used internationally as the reference method for proactive risk assessment (screening), assessment, monitoring and triaging for interventions in patients with cancer. This review aims to explain the rationale behind and data supporting the PG-SGA, and to provide an overview of recent developments in the utilization of the PG-SGA and the PG-SGA Short Form. The PG-SGA was designed in the context of a paradigm known as 'anabolic competence'. Uniquely, the PG-SGA evaluates the patient's status as a dynamic rather than static process. The PG-SGA has received new attention, particularly as a screening instrument for nutritional risk or deficit, identifying treatable impediments and guiding patients and professionals in triaging for interdisciplinary interventions. The international use of the PG-SGA indicates a critical need for high-quality and linguistically validated translations of the PG-SGA. As a 4-in-1 instrument, the PG-SGA can streamline clinic work flow and improve the quality of interaction between the clinician and the patient. The availability of multiple high-quality language versions of the PG-SGA enables the inclusion of the PG-SGA in international multicenter studies, facilitating meta-analysis and benchmarking across countries.

    Glaucoma represents a group of multifactorial diseases with a unifying pathology of progressive retinal ganglion cell (RGC) degeneration, causing irreversible vision loss. To test the hypothesis that RGCs are intrinsically vulnerable in glaucoma, we have developed an in vitro model using the SIX6 risk allele carrying glaucoma patient-specific induced pluripotent stem cells (iPSCs) for generating functional RGCs. Here, we demonstrate that the efficiency of RGC generation by SIX6 risk allele iPSCs is significantly lower than iPSCs-derived from healthy, age- and sex-matched controls. The decrease in the number of RGC generation is accompanied by repressed developmental expression of RGC regulatory genes. The SIX6 risk allele RGCs display short and simple neurites, reduced expression of guidance molecules, and immature electrophysiological signature. In addition, these cells have higher expression of glaucoma-associated genes, CDKN2A and CDKN2B, suggesting an early onset of the disease phenotype. Consistent with the developmental abnormalities, the SIX6 risk allele RGCs display global dysregulation of genes which map on developmentally relevant biological processes for RGC differentiation and signaling pathways such as mammalian target of rapamycin that integrate diverse functions for differentiation, metabolism, and survival. The results suggest that SIX6 influences different stages of RGC differentiation and their survival; therefore, alteration in SIX6 function due to the risk allele may lead to cellular and molecular abnormalities. These abnormalities, if carried into adulthood, may make RGCs vulnerable in glaucoma. Stem Cells 2017;35:2239-2252. © 2017 AlphaMed Press.

    The value of subjective global assessment (SGA) as nutritional assessor of protein-energy wasting (PEWSGA) in chronic kidney disease (CKD) patients depends on its mortality predictive capacity. We investigated associations of PEWSGA with markers of nutritional status and all-cause mortality in CKD patients. In 1031 (732 CKD1-5 non-dialysis and 299 dialysis) patients, SGA and body (BMI), lean (LBMI) and fat (FBMI) body mass indices, % handgrip strength (% HGS), serum albumin, and high sensitivity C-reactive protein (hsCRP) were examined at baseline. The five-year all-cause mortality predictive strength of baseline PEWSGA and during follow-up were investigated. PEWSGA was present in 2% of CKD1-2, 16% of CKD3-4, 31% of CKD5 non-dialysis and 44% of dialysis patients. Patients with PEWSGA (n = 320; 31%) had higher hsCRP and lower BMI, LBMI, FBMI, %HGS and serum albumin. But, using receiver operating characteristics-derived cutoffs, these markers could not classify (by kappa statistic) or explain variations of (by multinomial logistic regression analysis) presence of PEWSGA. In generalized linear models, SGA independently predicted mortality after adjustments of multiple confounders (RR: 1.17; 95% CI: 1.11-1.23). Among 323 CKD5 patients who were re-assessed after median 12.6 months, 222 (69%) remained well-nourished, 37 (11%) developed PEWSGA de novo, 40 (12%) improved while 24 (8%) remained with PEWSGA. The latter independently predicted mortality (RR: 1.29; 95% CI: 1.13-1.46). SGA, a valid assessor of nutritional status, is an independent predictor of all-cause mortality both in CKD non-dialysis and dialysis patients that outperforms non-composite nutritional markers as prognosticator.

    To explore the relationship between cervical spine and the global spine alignment and to postulate the hypotheses that a lordotic alignment of cervical spine is not the only standard to identify asymptomatic subjects, and the degenerative modification of cervical curves depends primarily on their spinal-pelvic alignment. A cohort of 120 cases of Chinese asymptomatic subjects and a cohort of 121 cases of Chinese cervical spondylotic patients were recruited prospectively from 2011 to 2012. Roussouly Classification was utilized to categorize all subjects and patients according to their thoracic spine, lumbar spine and pelvic alignment. The cervical alignments were evaluated as lordosis, straight, sigmoid or kyphosis. Through the lateral X-ray images of neutral cervical and global spine, a number of parameters were measured and analyzed, including pelvic incidence, pelvic tilt, sacral slope, thoracic kyphosis (TK), lumbar lordosis, global cervical angles (angles between two lines parallel with posterior walls of C2 and C7), practical cervical angles (the addition of different cervical end plate angles from C3 to C7, and inter-vertebral angles from C23 to C67), T1 slope, spinal sacral angles (SSA), Hip to C7/Hip to Sacrum and C0-C2 angle. The percentages of cervical lordosis were 28.3% and 36.4% in asymptomatic and spondylotic group, respectively. The cervical spine alignments correlated with Roussouly types of global spine alignment in both asymptomatic and cervical spondylotic group (P inter-vertebral angle in Roussouly Type 2 at C4-5 and C5-6 levels (P = 0.04 and 0.04, respectively), and in Roussouly Type 3 at C6-7 level (P = 0.01). The SSA showed significant difference between Roussouly Type 2 and 4 in asymptomatic subjects (P = 0.00), and between Type 1 and 3, 1 and 4, 2 and 3, 2 and 4 in cervical spondylotic patients (P = 0.01, 0.02, 0.00 and 0.01, respectively). The T1 slope was significantly different among Roussouly types (P = 0.04) with its largest value in

Methods: The whole-brain NAA concentration (WBNAA) was acquired with whole-head non-localizing proton MR spectroscopy. Fractional brain parenchymal volume (fBPV), T 2 and T 1 lesion loads, were obtained from the MRI in: (i) 24 BMS patients: 23.1 ± 7.2 years disease duration, median Expanded Disability Status Scale (EDSS) score of 2.0 (range: 0–3); (ii) 26 non-benign MS patients (non-BMS), 24.5 ± 7.4 years disease duration, median EDSS of 4.0 (range: 3.5–6.5); (iii) 15 healthy controls. Results: Controls’ 12.4 ± 2.3 mM WBNAA was significantly higher than the BMS's and non-BMS's 10.5 ± 2.4 and 9.9 ± 2.1 mM (both p < 0.02), but the difference between the patients’ groups was not (p > 0.4). Likewise, the controls’ 81.2 ± 4.5% fBPV exceeded the BMS and non-BMS's 77.0 ± 5.8% and 76.3 ± 8.6% (p < 0.03), which were also not different from one another (p > 0.7). BMS patients’ T 1 -hypointense lesion load, 2.1 ± 2.2 cm 3 , was not significantly different than the non-BMS's 4.1 ± 5.4 cm 3 (p > 0.08) and T 2 -hyperintense loads: 6.0 ± 5.7 cm 3 and 8.7 ± 7.8 cm 3 , were also not different (p > 0.1). Conclusions: WBNAA differentiates normal controls from MS patients but does not distinguish BMS from more disabled MS patients of similar disease duration. Nevertheless, all MS patients who remain RR for 15+ years suffered WBNAA loss similar to the average RR MS population at fourfold shorter disease duration suggesting relative global neuronal sparing or leveling-off of the neurodegeneration rate

    In metastatic testicular cancer patients treated with bleomycin, etoposide, and cisplatin (BEP) chemotherapy, bleomycin-induced pneumonitis is a well-known and potentially fatal side effect. We sought to determine the prevalence of lesions as signs of bleomycin-induced pulmonary changes on restaging computed tomography (CT) scans after treatment and to ascertain whether fibrosis markers were predictive of these changes. This prospective nonrandomized cohort study included metastatic testicular cancer patients, 18-50 years of age, treated with BEP chemotherapy. Restaging CT scans were examined for lesions as signs of bleomycin-induced pulmonary changes by two independent radiologists and graded as minor, moderate, or severe. Plasma samples were collected before, during, and after treatment and were quantified for transforming growth factor-β1 (TGF-β1), growth differentiation factor-15 (GDF-15), and high-sensitivity C-reactive protein (hs-CRP). In total, 66 patients were included: forty-five (68%) showed signs of bleomycin-induced pulmonary changes on the restaging CT scan, 37 of which were classified as minor and 8 as moderate. No differences in TGF-β1, GDF-15, or hs-CRP plasma levels were found between these groups. Bleomycin-induced pulmonary changes are common on restaging CT scans after BEP chemotherapy for metastatic testicular cancer. Changes in TGF-β1, GDF-15, and hs-CRP plasma levels do not differ between patients with and without radiological lesions as signs of bleomycin-induced pulmonary changes and are therefore not helpful as predictive biomarkers. Bleomycin-induced pneumonitis (BIP) is a well-known and potentially fatal side effect in metastatic testicular cancer patients treated with bleomycin, etoposide, and cisplatin chemotherapy. Currently, the decision to discontinue bleomycin administration is made during treatment and is based on clinical signs. An upfront or early marker or biomarker that identifies patients likely to develop BIP would be

    Various factors are reported to affect the spinal alignment in degenerative lumbar scoliosis (DLS). Although trunk muscles also appear to affect spinal alignment, the role of the trunk muscles is not yet clear. The aim was to elucidate the role of the multifidus (MF) and psoas (PS) in maintaining global spinal alignment in patients with DLS. This was a multicenter retrospective matched cohort study. Surgically treated 60 paired DLS and lumbar spinal stenosis (LSS) female (120 patients), matched for age and body mass index (BMI; DLS age 68.0±6.8 vs. LSS 67.1±8.9 years; BMI 21.6±3.3 vs. 23.2±3.8 kg/m(2)), were included and were followed for at least 2 years. Spinal alignment, muscle area, and volume were measured from radiographs, magnetic resonance images (MRIs), and whole-body dual-energy X-ray absorptiometry (DXA) scans. Muscle strength was measured by grip power and peak expiratory flow (PEF). As a surrogate of muscle area, we obtained the cross-sectional area (CSA) at the L5-S level from preoperative MRIs. The MF and PS CSAs were significantly smaller in the DLS group than in the LSS group (MF 477.7±192.5 vs. 779.8±248.6 mm(2), plean composition and grip strength or PEF tests between the groups. Correlation coefficient tests showed moderate correlations between the MF average CSA (avCSA) and global spinal alignment and spinopelvic alignment (pelvic incidence-lumbar lordosis; R=-0.37, -0.38) in the DLS group. The MF avCSA was correlated with the postoperative progression of kyphosis at the unfused thoracic vertebrae in the DLS group (R=0.34). The CSAs of the MF and PS were significantly smaller in the DLS group. Whole-body DXA showed no significant difference in the lean composition between the groups. There were significant correlations in the DLS patients between the MF CSA and sagittal spinal alignment. These findings suggest the causal relationship between muscles and global spine alignment.

    To evaluate nutritional status in adult patients with acute leukemia (AL) using patient-generated subjective global assessment (PG-SGA) and to investigate the influence of nutritional status on prognosis.We observationally investigated 68 adult patients with newly diagnosed AL who received PG-SGA at the First Hospital of Jilin University between May 2013 and July 2015. Clinical features, chemotherapy regimens, biochemical indexes, body composition, complete remission (CR) rate, minimal residual disease (MRD), survival time, and side-effects of chemotherapy were compared between patients with and without severe malnutrition.Mean PG-SGA scores of the total patients were 6.1 ± 4.0, and 19 of 68 (27.9%) patients had severe malnutrition (PG-SGA score ≥9). Patients with acute myeloid leukemia (AML) had higher scores than those with acute lymphocytic leukemia (ALL; P = .011) and high-risk patients had higher scores regardless of whether they had AML or ALL (AML, P = .012; ALL, P = .043). Univariate analysis showed that severe malnutrition was correlated with age (P = .041), transferrin (P = .042), Karnofsky Performance Status score (P = .006), and C-reactive protein (CRP) (P = .018). Multivariate analysis demonstrated that severe malnutrition was associated with CRP (hazard ratio [HR] = 1.020, 95% confidence interval [CI]: 1.002-1.039, P = .026). No difference was found in CR rate (P = .831) between patients with and without malnutrition, but those who were severely malnourished had higher MRD (P = .048 in AML patients, P = .036 in ALL patients) and more gastrointestinal side-effects (P = .014). Severe malnutrition was also associated with inferior overall survival (HR = 0.243, 95% CI: 0.063-0.945, P = .041) but not with event-free survival (HR = 0.808, 95% CI: 0.338-1.934, P = .663).Severe malnutrition defined by PG-SGA in adult patients with de novo AL may result in poor outcome.

    Nursing is an integral part of all healthcare services, and has the potential of having a wide and enduring impact on health outcomes for a global ageing population. Over time nurses have developed new roles and assumed greater responsibilities. It is increasingly important to demonstrate the safety and overall impact of nurses' practice through research, to support the case for greater investment and development of nursing services around the world. To provide an overview of existing research evidence on the impact of nursing on patient outcomes, identify gaps in evidence, and point to future priorities for global research. Specifically to address two questions: what is the evidence that nursing contributes to improving the health and well-being of populations?; and where should research activity be focused to strengthen the evidence base for the impact of nursing? A search of the literature from 1996 using CINAHL, MEDLINE, the Cochrane Library, Google Scholar and the NICE evidence databases using the key words: nursing, nurse led, nursing interventions and patient outcomes. Initial analysis of the retrieved citations to reveal clusters of evidence of nursing impact in clinical areas which had been subject to systematic/integrative reviews or meta-analyses. Further analysis of these reviews to provide an overview of the research evidence for nurses' contributions to healthcare to inform discussion on future research agendas. We use the terms low, moderate and high quality evidence to reflect the assessments made by the review authors whose work is presented throughout. Analysis of 61 reviews, including ten Cochrane reviews and two scoping/selective reviews to provide a summary of the research evidence for nurses' contributions to healthcare in the following areas of practice: nursing in acute care settings; nurses' involvement in public health; the contribution of specialist nurse and nurse-led services to the management of chronic disease; comparison of care

    Full Text Available Objective To assess the nutritional status of patients on maintenance hemodialysis by using modified quantitative subjective global assessment (MQSGA and anthropometric measurements. Method We Conducted a cross sectional descriptive analytical study to assess the nutritional status of fifty four patients with chronic kidney disease undergoing maintenance hemodialysis by using MQSGA and different anthropometric and laboratory measurements like body mass index (BMI, mid-arm circumference (MAC, mid-arm muscle circumference (MAMC, triceps skin fold (TSF and biceps skin fold (BSF, serum albumin, C-reactive protein (CRP and lipid profile in a government tertiary hospital at Kathmandu, Nepal. Results Based on MQSGA criteria, 66.7% of the patients suffered from mild to moderate malnutrition and 33.3% were well nourished. None of the patients were severely malnourished. CRP was positive in 56.3% patients. Serum albumin, MAC and BMI were (mean + SD 4.0 + 0.3 mg/dl, 22 + 2.6 cm and 19.6 ± 3.2 kg/m 2 respectively. MQSGA showed negative correlation with MAC ( r = −0.563; P = < 0.001, BMI ( r = −0.448; P = < 0.001, MAMC ( r = −0.506; P = < .0001, TSF ( r = −0.483; P = < .0002, and BSF ( r = −0.508; P = < 0.0001. Negative correlation of MQSGA was also found with total cholesterol, triglyceride, LDL cholesterol and HDL cholesterol without any statistical significance. Conclusion Mild to moderate malnutrition was found to be present in two thirds of the patients undergoing hemodialysis. Anthropometric measurements like BMI, MAC, MAMC, BSF and TSF were negatively correlated with MQSGA. Anthropometric and laboratory assessment tools could be used for nutritional assessment as they are relatively easier, cheaper and practical markers of nutritional status.

    Full Text Available Global brachial plexopathies cause major sensory and motor deficits in the affected arm and hand. Many patients report of psychosocial consequences including chronic pain, decreased self-sufficiency, and poor body image. Bionic reconstruction, which includes the amputation and prosthetic replacement of the functionless limb, has been shown to restore hand function in patients where classic reconstructions have failed. Patient selection and psychological evaluation before such a life-changing procedure are crucial for optimal functional outcomes. In this paper we describe a psychosocial assessment procedure for bionic reconstruction in patients with complete brachial plexopathies and present psychosocial outcome variables associated with bionic reconstruction.Between 2013 and 2017 psychosocial assessments were performed in eight patients with global brachial plexopathies. We conducted semi-structured interviews exploring the psychosocial adjustment related to the accident, the overall psychosocial status, as well as motivational aspects related to an anticipated amputation and expectations of functional prosthetic outcome. During the interview patients were asked to respond freely. Their answers were transcribed verbatim by the interviewer and analyzed afterwards on the basis of a pre-defined item scoring system. The interview was augmented by quantitative evaluation of self-reported mental health and social functioning (SF-36 Health Survey, body image (FKB-20 and deafferentation pain (VAS. Additionally, psychosocial outcome variables were presented for seven patients before and after bionic reconstruction.Qualitative data revealed several psychological stressors with long-term negative effects on patients with complete brachial plexopathies. 88% of patients felt functionally limited to a great extent due to their disability, and all of them reported constant, debilitating pain in the deafferented hand.

    Full Text Available Background: To assess regional systolic function and global contractile function in patients with WPW Syndrome.Method: Eleven cases with manifest Wolff-Parkinson-White (WPW syndrome in sinus rhythm were compared to 11 age matched controls. 2D strain analysis was performed and peak segmental radial strain (pRS values obtained from basal ventricular parasternal short-axis images (70 ± 5 frames/sec using a dedicated software package. Heterogeneity of radial strain pattern in six circumferential basal left ventricular segments was measured in terms of standard deviations of peak RS (SDpRS or range (difference between maximum and minimum peak RS i.e. RangepRS. Spectral Doppler (continuous wave measurements were acquired through the left ventricular outflow tract to determine Pre Ejection Period (PEP, Left Ventricular Ejection Time (LVET and measures of left ventricular systolic performance. Results: LV segmental radial strain was profoundly heterogeneous in WPW cases in contrast to fairly homogenous strain pattern in normal subjects. Wide SDpRS values 17.5 ± 8.9 vs 3.3 ± 1.4, p<0.001 and RangepRS 42.7 ± 20.8 vs.8.5 ± 3.6 , p<0.001 were observed among WPW and healthy subjects respectively. PEP (132.4 ± 14.7 vs 4.7 ± 0.5ms, p<0.001 and corrected PEP (76.1 ± 8.0 vs 2.7 ± 0.4ms, p<0.001 were significantly longer in WPW patients compared to controls. The PEP/LVET ratio was also significantly greater in WPW cohort (0.49 ± 0.04 vs. 0.28 ± 0.05, p <0.001 suggesting global systolic dysfunction. Conclusion: Patients with manifest preexcitation (predominantly those with right-sided pathways have regional and global contractile dysfunction resulting from aberrant impulse propagation inherent to the preexcited state.

    Hepatitis C virus (HCV) persistence results from inefficiencies of both innate and adaptive immune responses to eradicate the infection. A functional impairment of circulating Vγ9Vδ2 T-cells was described but few data are available on Vγ9Vδ2 T-cells in the liver that, however, represents the battlefield in the HCV/host interaction. Aim of this work was to compare circulating and intrahepatic Vγ9Vδ2 T-cells in chronic HCV-infected patients (HCV pos ) and in HCV-negative (HCV neg ) subjects. Phenotypic and functional analysis was performed by flow cytometry. Anti-HCV activity was analyzed by using an in vitro autologous liver culture system. Independently from HCV infection, the liver was enriched of Vγ9Vδ2 T-cells expressing an effector/activated phenotype. In contrast, an enrichment of PD-1 expressing Vγ9Vδ2 T-cells was observed both in the peripheral blood and in the liver of HCV pos patients, probably due to a persistent antigenic stimulation. Moreover, a lower frequency of IFN-γ producing Vγ9Vδ2 T-cells was observed in the liver of HCV pos patients, suggesting a functional impairment in the cytokine production in HCV pos liver. Despite this hypo-responsiveness, intrahepatic Vγ9Vδ2 T-cells are able to exert an anti-HCV activity after specific stimulation. Altogether, our data show that HCV infection induced a dysregulation of intrahepatic Vγ9Vδ2 T cells that maintain their anti-HCV activity after specific stimulation. A study aimed to evaluate the mechanisms of the antiviral activity may be useful to identify new pathways able to improve Vγ9Vδ2 T-cells intrahepatic function during HCV infection.

    We report the case of a presenile woman with Cotard syndrome, in the context of major depression, who showed an improvement in bilateral frontal hypoperfusion in a SPECT study using 99mTc-HMPAO after undergoing successful treatment with antidepressant therapy. We also retrospectively evaluated her clinical course based on the clinical stages. The symptoms of Cotard syndrome have been reported to change dramatically according to the stages. This peculiarity made it difficult for us to rapidly diagnose Cotard syndrome in the context of major depression, and not dementia, and thereby adequately treat the patient in our case. Differences in the reduced blood flow regions and a time lag from psychiatric remission were observed before the improvement in the SPECT findings when comparing our case with a previously reported case of Cotard syndrome. These differences suggest that the mechanism of Cotard syndrome is still not well understood at the present time.

    An increase in the dialysis programme expenditure is expected in most countries given the continued rise in the number of people with end-stage renal disease (ESRD) globally. Since chronic peritoneal dialysis (PD) therapy is relatively less expensive compared with haemodialysis (HD) and because there is no survival difference between PD and HD, identifying factors associated with PD use is important. Incidence counts for the years 2003-05 were available from 36 countries worldwide. We studied associations of population characteristics, macroeconomic factors and renal service indicators with the percentage of patients on PD at Day 91 after starting dialysis. With linear regression models, we obtained relative risks (RRs) with 95% confidence intervals (CIs). The median percentage of incident patients on PD was 12% (interquartile range: 7-26%). Determinants independently associated with lower percentages of patients on PD were as follows: patients with diabetic kidney disease (per 5% increase) (RR 0.93; 95% CI 0.89-0.97), health expenditure as % gross domestic product (per 1% increase) (RR 0.93; 95% CI 0.87-0.98), private-for-profit share of HD facilities (per 1% increase) (RR 0.996; 95% CI 0.99-1.00; P = 0.04), costs of PD consumables relative to staffing (per 0.1 increase) (RR 0.97; 95% CI 0.95-0.99). The factors associated with a lower percentage of patients on PD include higher diabetes prevalence, higher healthcare expenditures, larger share of private-for-profit centres and higher costs of PD consumables relative to staffing. Whether dialysis modality mix can be influenced by changing healthcare organization and funding requires additional studies.

    Colorectal cancer is the third and the second most common cancer worldwide in men and women respectively, and the second in Malaysia for both genders. Surgery, chemotherapy and radiotherapy are among the options available for treatment of patients with colorectal cancer. In clinical trials, the main purpose is often to compare efficacy between experimental and control treatments. Treatment comparisons often involve several responses or endpoints, and this situation complicates the analysis. In the case of colorectal cancer, sets of responses concerned with survival times include: times from tumor removal until the first, the second and the third tumor recurrences, and time to death. For a patient, the time to recurrence is correlated to the overall survival. In this study, global score test methodology is used in combining the univariate score statistics for comparing treatments with respect to each survival endpoint into a single statistic. The data of tumor recurrence and overall survival of colorectal cancer patients are taken from a Malaysian hospital. The results are found to be similar to those computed using the established Wei, Lin and Weissfeld method. Key factors such as ethnic, gender, age and stage at diagnose are also reported.

    Background: DNA methylation plays a vital role in the pathogenesis of the myelodysplastic syndrome (MDS), a heterogeneous group of clonal hematopoietic stem cell (HSC) disorders. It is reported to be an independent prognostic factor affecting overall survival (OS). Our aim was to analyze the role of global DNA methylation using an anti-5-methylcytosine (5-MC) antibody by immunohistochemistry (IHC) of bone marrow biopsy (BM Bx) specimens in MDS patients, assessing correlations with various clinical and biological prognostic factors. Material and methods: A total of 59 MDS cases, classified as per the World Health Organization (WHO) 2008 guidelines, were evaluated over a period of 4 years. Clinical data were retrieved from departmental case records and anti-5-MC expression was analyzed with formalin fixed paraffin embedded sections of BM Bx specimens of MDS patients and controls. Results: The median age at diagnosis was 52 years (15-85years). Patients were categorized into low risk (59%) and high risk (41%) according to International Prognostic Scoring System (IPSS). The median follow-up time was 10 months (1 to 37 months). We generated a methylation score (M-score) using anti-5-MC and with the derived cut-off of 30.5 from the receiver operator curve (ROC), there was a significant difference between the two groups in the percentage of BM blasts (p=0.01), WHO sub-type (p=0.01), IPSS (p=0.004), progression to AML (p=0.04) on univariate analysis. Interestingly, patients showing a high M-score (M-score ≥ 30.5) demonstrated a significantly shorter OS and progression to AML. However, on multivariate analysis, only BM blasts (p=0.01) and IPSS (p=0.02) remained independent variables for progression to AML and OS respectively. Conclusion: Immunostaining with anti-5-MC antibody with BM Bx samples is a simple and cost effective technique to detect global methylation, a powerful tool to predict overall survival in patients with MDS.

    Full Text Available This study aimed to determine the extent of impairment in social and non-social cognitive domains in an ecological context comparing bipolar (BD, schizophrenic patients (SKZ and healthy controls (HC. The sample was enrolled at the Department of Psychiatry of Policlinico Hospital, University of Milan, it includes stabilized schizophrenic patients (n = 30, euthymic bipolar patients (n = 18 and healthy controls (n = 18. Patients and controls completed psychiatric assessment rating scales, the Brief Assessment of Cognition in Schizophrenia (BACS and the Executive and Social Cognition Battery (ESCB that contains both ecological tests of executive function and social cognition, in order to better detect cognitive deficits in patients with normal results in standard executive batteries. The three groups differed significantly for gender and substance abuse, however the differences did not influence the results. Bipolar patients showed less impairment on cognitive performance compared to schizophrenic patients, even in ecological tests that mimic real life scenarios. In particular, BD performed better than SKZ in verbal memory (p

    Breast cancer-related lymphoedema (BCRL) is a result of interaction between several pathophysiological processes, and is not simply a 'stopcock' effect resulting from removal of axillary lymph nodes. The aim of this study was to test the hypothesis that there is a constitutional 'global' lymphatic dysfunction in patients who develop BCRL. Lower-limb lymphoscintigraphy was performed in 30 women who had undergone axillary lymph node dissection at least 3 years previously, of whom 15 had BCRL and 15 did not. No patient had any clinical abnormality of the lower limb. The control group comprised 24 women with no history of cancer or lower-limb lymphoedema. (99m) Tc-Nanocoll was injected subcutaneously into the first webspace of each foot, followed by whole-body imaging. Scans were reported as abnormal if there was delay in lymph transport or rerouting through skin or deep system. Quantification was expressed as the percentage injected activity accumulating in ilioinguinal nodes. Mean(s.d.) ilioinguinal nodal accumulation at 150 min was significantly lower in women with BCRL than in those without (2·7(2·5) versus 5·9(4·8) per cent respectively; P = 0·006). Abnormal findings on lower-limb lymphoscintigraphy were observed in 17 of the 30 patients: ten of the 15 women who had BCRL and seven of the 15 who did not. None of the 24 control subjects had abnormal scan findings. Women with BCRL had reduced lower-limb lymph drainage, supporting the hypothesis of a predisposition to BCRL. A surprisingly high proportion of patients with breast cancer also demonstrated lymphatic dysfunction, despite clinically normal lower limbs. Possible explanations could be a systemic effect of breast cancer or its treatment, or an unidentified association between breast cancer and lymphatic dysfunction.

    Full Text Available We describe our semi-automatic segmentation of whole-body diffusion-weighted MRI (WBDWI using a Markov random field (MRF model to derive tumor total diffusion volume (tDV and associated global apparent diffusion coefficient (gADC; and demonstrate the feasibility of using these indices for assessing tumor burden and response to treatment in patients with bone metastases. WBDWI was performed on eleven patients diagnosed with bone metastases from breast and prostate cancers before and after anti-cancer therapies. Semi-automatic segmentation incorporating a MRF model was performed in all patients below the C4 vertebra by an experienced radiologist with over eight years of clinical experience in body DWI. Changes in tDV and gADC distributions were compared with overall response determined by all imaging, tumor markers and clinical findings at serial follow up. The segmentation technique was possible in all patients although erroneous volumes of interest were generated in one patient because of poor fat suppression in the pelvis, requiring manual correction. Responding patients showed a larger increase in gADC (median change = +0.18, range = -0.07 to +0.78 × 10(-3 mm2/s after treatment compared to non-responding patients (median change = -0.02, range = -0.10 to +0.05 × 10(-3 mm2/s, p = 0.05, Mann-Whitney test, whereas non-responding patients showed a significantly larger increase in tDV (median change = +26%, range = +3 to +284% compared to responding patients (median change = -50%, range = -85 to +27%, p = 0.02, Mann-Whitney test. Semi-automatic segmentation of WBDWI is feasible for metastatic bone disease in this pilot cohort of 11 patients, and could be used to quantify tumor total diffusion volume and median global ADC for assessing response to treatment.

    In the present study, we assessed the role of Global Longitudinal Strain (GLS) as a predictor of all-cause mortality in patients with severe aortic valve stenosis (AS), irrespective of their type of treatment. Data of 807 patients with AS receiving complete echocardiographic and clinical examination were retrospectively analyzed. Valve area <1 cm 2 and sufficient image quality were inclusion criteria; patients with severe concomitant valvulopathy were excluded. Patients were grouped into treatment (aortic valve replacement [AVR]) and conservative (non-AVR) groups. Multivariable Cox analysis was used to assess predictors of all-cause mortality. Five hundred fourteen patients were included and 53.3% were of male gender. Mean age at inclusion was 76.4 ± 9.8 years; 326 received AVR. Death from any cause occurred in 72.9% of non-AVR group and 17.8% of AVR group (p <0.001). GLS (expressed as |%|) was found to be an independent predictor of all-cause mortality in non-AVR group (hazard ratio [HR] 0.933, 95% CI 0.854 to 0.987, p = 0.038). In patients receiving AVR, GLS and history of coronary artery bypass graft were found to be independent predictors of all-cause mortality (HR for GLS 0.912, 95% CI 0.730 to 0.999, p = 0.048; HR for coronary artery bypass graft 2.977, 95% CI 1.014 to 6.273, p = 0.013). In non-AVR patients, GLS <9.7% showed a higher 1- and 5-year mortality (log rank p values of 0.002 and 0.010, respectively). In conclusion, GLS is an independent predictor of all-cause mortality in severe AS, irrespective of their type of treatment. GLS <9.7% indicates a significantly higher 1- and 5-year mortality in non-AVR patients. Therefore, GLS should be regularly assessed for enhanced risk stratification and clinical decision-making.

    Alcoholism causes psychological, behavioral and cognitive symptoms that need to be addressed together. The neuropsychological alterations among alcohol-dependent people are considered to make the therapeutic work complex and longer. A cognitive rehabilitation program is sometimes difficult to achieve with these patients. Functional results are often difficult to anticipate. However, the consequences of this therapeutic approach are multiple and there are many interactions between psycho-affective, behavioral and cognitive components. A neuropsychological approach can be used like a tool to improve metacognition. A bad contribution to treatment programs is often secondary to the illusion of a satisfying intellectual functioning. Patients' motivation for the therapeutic work is very changeable. A complete consciousness of impairments can help them to stay involved. The following case shows the cognitive effects and secondary benefits associated with a neuropsychological work, which was carried out by a chronic ethylic patient with severe physical and cognitive symptoms. The patient aged 50, with a good qualification level (scientific section in the final year of secondary school, with no diploma, then attended a training program to become a croupier) was suffering from chronic alcoholism since his adolescence. He arrived in the closed unit after many hospitalizations in psychiatric and hepato-gastroenterology units. He had been showing mental confusion. He presented a frontal and subcortical profile of alcohol-related dementia according to Oslin's criteria. MRI revealed global cerebral atrophy, more pronounced on the fronto-parietal cortex with cerebellar leukoencephalopathy, but no pontine central myelinolysis. The neurocognitive program had two main lines: reducing attentional, executive and graphical deficits with training exercises (individual and group sessions) and compensating memory, and executive disorders with an external aid. The cognitive program had been

    Full Text Available BackgroundThe assessment and treatment of complex disorders is challenged by the multiple domains and instruments used to evaluate clinical outcome. With the large number of assessment tools typically used in complex disorders comes the challenge of obtaining an integrative view of disease status to further evaluate treatment outcome both at the individual level and at the group level. Radar plots appear as an attractive visual tool to display multivariate data on a two-dimensional graphical illustration. Here, we describe the use of radar plots for the visualization of disease characteristics applied in the context of tinnitus, a complex and heterogeneous condition, the treatment of which has shown mixed success.MethodsData from two different cohorts, the Swedish Tinnitus Outreach Project (STOP and the Tinnitus Research Initiative (TRI database, were used. STOP is a population-based cohort where cross-sectional data from 1,223 non-tinnitus and 933 tinnitus subjects were analyzed. By contrast, the TRI contained data from 571 patients who underwent various treatments and whose Clinical Global Impression (CGI score was accessible to infer treatment outcome. In the latter, 34,560 permutations were tested to evaluate whether a particular ordering of the instruments could reflect better the treatment outcome measured with the CGI.ResultsRadar plots confirmed that tinnitus subtypes such as occasional and chronic tinnitus from the STOP cohort could be strikingly different, and helped appreciate a gender bias in tinnitus severity. Radar plots with greater surface areas were consistent with greater burden, and enabled a rapid appreciation of the global distress associated with tinnitus in patients categorized according to tinnitus severity. Permutations in the arrangement of instruments allowed to identify a configuration with minimal variance and maximized surface difference between CGI groups from the TRI database, thus affording a means of optimally

    Cognitive impairments have been reported to be more common in non-demented patients with Parkinson's disease (PD) and education levels play an important role in intelligence. The studies on cognitive impairments in Chinese PD patients with higher education levels and normal global cognition according to Mini-Mental State Examination Score (MMSE) have not been reported. We enrolled 69 consecutive PD patients with over 6 years education levels and a MMSE score above 24 (of 30) and performed a battery of neuropsychological scales. There are extensive cognitive domain impairments in PD patients with "normal" global cognitive according to MMSE. Montreal Cognitive Assessment (MoCA) is a highly sensitive scale to screen cognitive impairments in PD. The cutoff score of 28 on the MMSE screening for cognitive impairment in Chinese PD patients with high education levels may be more appropriate.

    Parkinson’s disease (PD) is a neurodegenerative disorder of unknown etiology. It is considered as a multifactorial disease dependent on environmental and genetic factors. Deregulation in cell degradation has been related with a significant increase in cell damage, becoming a target for studies on the PD etiology. In the present study, we have characterized the parkinsonian toxin 1-methyl-4-phenylpyridinium ion (MPP + )-induced damage in fibroblasts from Parkinson’s patients with the mutation G2019S in leucine-rich repeat kinase 2 protein (LRRK2) and control individuals without this mutation. The results reveal that MPP + induces mTOR-dependent autophagy in fibroblasts. Moreover, the effects of caspase-dependent cell death to MPP + were higher in cells with the G2019S LRRK2 mutation, which showed basal levels of autophagy due to the G2019S LRRK2 mutation (mTOR-independent). The inhibition of autophagy by 3-methyladenine (3-MA) treatment reduces these sensitivity differences between both cell types, however, the inhibition of autophagosome–lysosome fusion by bafilomycin A1 (Baf A1) increases these differences. This data confirm the importance of the combination of genetic and environmental factors in the PD etiology. Thereby, the sensitivity to the same damage may be different in function of a genetic predisposition, reason why individuals with certain mutations can develop some early-onset diseases, such as individuals with G2019S LRRK2 mutation and PD

    To evaluate the nutritional status of non-critically ill digestive surgery patients at the moment of parenteral nutrition initiation using three different nutritional test tools and to study their correlation. To study the association between the tests and the clinical and laboratory parameters used in the follow-up of PN treatment. Prospective study over 4 months. Anthropometric and clinical variables were recorded. Results of Subjective Global Assessment; Patient-Generated Subjective Global Assessment; and Nutritional Risk Screening 2002 were compared applying kappa test. Relationship between the clinical and laboratory parameters with Subjective Global Assessment was studied by multinominal regression and with the other two tests by multiple linear regression models. Age and sex were included as adjustment variables. Malnutrition in 45 studied patients varied from 51% to 57%. Subjective Global Assessment correlated well with Patient-Generated Subjective Global Assessment and Nutritional Risk Screening 2002 (κ = 0531 p = 0.000). The test with the greatest correlation with the clinical and analytical variables was the Nutritional Risk Screening 2002. Worse nutritional state in this test was associated with worse results in albumin (B = -0.087; CI = -0.169/-0.005], prealbumin (B = -0.005; CI = [-0.011/-0.001]), C-reactive protein (B = 0.006;CI = [0.001/ 0.011]) and leukocytes (B = 0.134; CI = [0.031/0.237]) at the en of parenteral nutrition treatment. Half of the digestive surgery patients were at malnutritional risk at the moment of initiating parenteral nutrition. Nutritional Risk Screening 2002 was the test with best association with the parameters used in the clinical follow-up of parenteral nutrition treated patients. Copyright AULA MEDICA EDICIONES 2014.

    With diabetes rates escalating globally, there is the need for a better integration of all aspects of diabetes care for improved population outcomes. An understanding, not only of regional but global literature on physical activity barriers and its facilitators is important if healthcare providers and policy makers are to create programs tailored to their populations. Herein, we report the results of a narrative review of the global barriers and facilitators of physical activity for patients with diabetes mellitus. An in-depth literature search was conducted to identify English-language studies that examined physical activity barriers and associated facilitators among patients with diabetes mellitus. Major electronic literature databases that were searched included Google Scholar, PubMed, Hub-Med, and Highwire. Studies were available from Africa, Asia, Australia, Europe, and, predominantly North America. A total of 34 predominantly internal barriers emerged globally. The most commonly reported were time constrains, fear of provoking additional disorders, exercise venue and weather related barriers. Facilitators of physical activity were reported for most of the internal barriers (e.g. time constraints, lack of knowledge etc) while the external barriers (e.g. weather, environmental pollution etc) received only a minimal attention. Globally, patients with diabetes are confronted with an enormous number of physical activity barriers. Unlike the robust solutions proffered for the internal barriers, the literature is largely silent about solutions to the external barriers, which though fewer, may be highly influential. Additional data is needed to better understand physical activity behaviors in populations outside of North America.

    We report a patient driven home care system that successfully assisted 24/7 with the management of a 68-year-old woman after a stroke-a global illness. The patient's caregiver and physician used computer devices, smartphones and internet access for information exchange. Patient, caregiver, family and physician satisfaction, coupled with outcome and cost were indictors of quality of care. The novelty of this basic model of teleneurology is characterised by implementing a patient/caregiver driven system designed to improve access to cost-efficient neurological care, which has potential for use in primary, secondary and tertiary levels of healthcare in rural and underserved regions of the world. We suggest involvement of healthcare stakeholders in teleneurology to address this global problem of limited access to neurological care. This model can facilitate the management of neurological diseases, impact on outcome, reduce frequency of consultations and hospitalisations, facilitate teaching of healthcare workers and promote research. 2016 BMJ Publishing Group Ltd.

    BACKGROUND: New foods may present a risk for food hypersensitive patients. Several examples exist of allergic reactions caused by cross-reactive plant-derived foods, and new foods should be scrutinised before introducing them to the market. We have evaluated the clinical and serological relevance...... previously. To determine the biological and clinical relevance of the cross-reactivity, histamine release (HR) test, skin prick test (SPT) and food challenge were used. RESULTS: There was prevalence for reactivity against Nangai in the group of pollen allergic patients. This cross-reactivity seems...... to be related--at least in part--to carbohydrate epitopes. Three out of 12 patients tested with Nangai were positive upon open challenge, but using double blind placebo controlled food challenge (DBPCFC) this could not be confirmed in two patients. The biological effects of Nangai on allergic patients were...

    Although legally anchored, there are no empirical results from German second opinion programs. In this study, various aspects within a population of a second opinion program are examined. In this study patients were analyzed who sought a second opinion in the period from August 2011 to December 2016. Differences in patient characteristics, differentiated by agreement of first and second opinion, were analyzed using multivariate logistic regression. Patients' satisfaction and quality of life were examined one, three and six months after obtaining the second opinion. In total, 1,414 patients sought a second opinion. Most frequent medical indications were the knee (38.7 %), the back (26.8 %), the hip (11.7 %), and the shoulder (10.2 %). Except for the indication (p=0.035), no patient characteristic had influence on the conformation of the second opinion. Approximately two out of three initial recommendations were not confirmed by the specialists. 89 % of the patients were satisfied or very satisfied with the second opinion and the service offered. The second opinion offers patients the opportunity to seek an additional independent medical opinion and thus provide support for decision making. Further research is needed to examine the reasons for the high discrepancies between the first and second opinions. Copyright © 2018. Published by Elsevier GmbH.

    Situation awareness (SA) is defined as the perception of elements in the environment within a volume of time and space, the comprehension of their meaning, and the projection of their status in the near future. This construct is vital to decision making in intense, dynamic environments. It has been used in aviation as it relates to pilot performance, but has not been applied to medical education. The most widely used objective tool for measuring trainee SA is the Situation Awareness Global Assessment Technique (SAGAT). The purpose of this study was to design and validate SAGAT for assessment of practical trauma skills, and to compare SAGAT results to traditional checklist style scoring. Using the Human Patient Simulator, we designed SAGAT for practical trauma skills assessment based on Advanced Trauma Life Support objectives. Sixteen subjects (four staff surgeons, four senior residents, four junior residents, and four medical students) participated in three scenarios each. They were assessed using SAGAT and traditional checklist assessment. A questionnaire was used to assess possible confounding factors in attaining SA and overall trainee satisfaction. SAGAT was found to show significant difference (analysis of variance; p level of training lending statistical support to construct validity. SAGAT was likewise found to display reliability (Cronbach's alpha 0.767), and significant scoring correlation with traditional checklist performance measures (Pearson's coefficient 0.806). The questionnaire revealed no confounding factors and universal satisfaction with the human patient simulator and SAGAT. SAGAT is a valid, reliable assessment tool for trauma trainees in the dynamic clinical environment created by human patient simulation. Information provided by SAGAT could provide specific feedback, direct individualized teaching, and support curriculum change. Introduction of SAGAT could improve the current assessment model for practical trauma education.

    Patients with aneurysmal subarachnoid haemorrhage (aSAH) have impaired sleep and cognitive performance together with more difficulties in social and everyday life. Hypocortisolism has also been reported. However, a study assessing all dimensions between aSAH severity, objective and subjective sleep, cortisol secretion, cognitive performance and social and everyday life has not so far been performed. The aim of the present study was therefore two-fold: (1) to assess, in a sample of patients with aSAH, objective and subjective sleep, cognitive functioning, social skills and cortisol secretion concurrently, and (2) to compare patients on these variables with a control group. Twenty-one patients (17 females; mean age: 58.80 years) with ruptured aneurysm and surgical intervention and 21 (14 females; mean age: 58.90 years) age- and gender-matched controls took part in the study. Assessments covered objective sleep-EGG recordings, subjective sleep, salivary cortisol analysis, and psychological functioning including memory performance, mood, and emotion recognition. Compared to healthy controls, patients had lower scores for verbal memory performance and emotion recognition; they also reported more marked depressive symptoms and complained of poor sleep. However, no differences were found for objective sleep or cortisol secretion. Subjective and objective sleep, cortisol secretion and psychological functioning were unrelated. Findings indicate that patients with aSAH face psychological rather than physiological issues.

    The objectives of this analysis were to examine how patients' global severity with Alzheimer's disease (AD) relates to costs of care and explore the incremental effects of global severity measured by the clinical dementia rating (CDR) scale on these costs for patients in Spain. The Codep-EA study is an 18-multicenter, cross-sectional, observational study among patients (343) with AD according to the CDR score and their caregivers in Spain. The data obtained included (in addition to clinical measures) also socio-demographic data concerning the patient and its caregiver. Cost analyses were based on resource use for medical care, social care, caregiver productivity losses, and informal caregiver time reported in the resource utilization in dementia (RUD). Lite instrument and a complementary questionnaire. Multivariate regression analysis was used to model the effects of global severity and other socio-demographic and clinical variables on cost of care. The mean (standard deviation) costs per patient over 6 months for direct medical, social care, indirect and informal care costs, were estimated at €1,028.1 (1,655.0), €843.8 (2,684.8), €464.2 (1,639.0) and €33,232.2 (30,898.9), respectively. Dementia severity, as having a CDR score 0.5, 2, or 3 with CDR score 1 being the reference group were all independently and significantly associated with informal care costs. Whereas having a CDR score of 2 was also significantly related with social care costs, a CDR score of 3 was associated with most cost components including direct medical, social care, and total costs, all compared to the reference group. The costs of care for patients with AD in Spain are substantial, with informal care accounting for the greatest part. Dementia severity, measured by CDR score, showed that with increasing severity of the disease, direct medical, social care, informal care and total costs augmented.

    With the development of magnetic resonance imaging (MRI) and publications about radiologically isolated syndrome (RIS), a lot of patients are referred to multiple sclerosis (MS) tertiary centers to confirm diagnosis of RIS or MS when brain T2 abnormalities are identified, whatever their characteristics. We evaluate prospectively the occurrence of RIS or MS and sensitivity, specificity and predictive value of McDonald criteria in diagnosis for patients presenting with incidental brain MRI T2 lesions. The authors ran standardized procedures on 220 consecutive patients addressed by general practitioners or neurologists to confirm RIS or MS diagnosis on brain MRI and give a therapeutic advice. All patients underwent neurological tests, extensive blood screening, cerebrospinal fluid (CSF) examination, visual evoked potential (VEP) and follow-up MRI after 3, 6, 12 and 24 months to consider dissemination in time and space. Patient characteristics were: 165 women and 55 men, mean age: 42.7 years old (23-59). The major symptom motivating MRI was headaches (39%), sensitive atypical manifestations or pain (12%), mood disorders (10%), transient visual symptoms (9%), fatigue (8%), hormonal screening (6%), vertigo (6%), cranial trauma (5%), and dummy run for clinical study (5%). After a structured analysis of T2 lesions, the suspected diagnosis was: inflammatory disease 45%, vascular 33%, non-pathological 19%, genetic 2%, and metabolic 1%. Extensive screening confirmed the proposed diagnosis in 97% of cases. Among all the 220 proposed RIS patients, only 35.4% fulfilled the 2010 McDonald criteria, and 8% can be categorized as RIS. Dissemination in time criteria was present for 82.7% of MS patients and 36% of RIS patients but none of the vascular or non-pathological T2 abnormalities. Even if RIS was initially suspected on MRI, only a third of the patients had an inflammatory disease. Most of the patients had either non-specific T2 lesions or a non-inflammatory disease. Others

    Virtually no research has been conducted on patient assessments of traditional medicines and allopathic medicines for cancer care in poorer countries marked by pluralistic medical environments. Pakistan represents an excellent case for such a study because of the coexistence of culturally and historically specific indigenous traditional medicine, the strong presence of allopathic medicine, and, to a lesser extent, the availability of some globalized complementary and alternative medicines. To gain a preliminary understanding of cancer patients' perceptions of effectiveness and satisfaction with traditional medicine, globalized complementary and alternative medicine, and allopathy in the context of a pluralistic medical environment. Structured survey of 362 cancer patients, from diverse regions in the Punjab province and Northwest Frontier province, who were being treated in 4 different hospitals in Lahore, Pakistan. Use of traditional medicine remains high among cancer patients, with traditional healers used by the majority of those surveyed. Although patients' perceptions of the overall effectiveness of traditional medicines for treating cancer are low, those patients who do use traditional medicines still have high levels of satisfaction with these modalities. This is distinct from levels of satisfaction with, and perceptions of effectiveness of, Western cancer treatments, which were synonymous in this group of patients. Important differences in patient perceptions were found within groups (eg, between different forms of traditional healers) as well as between them. This study showed considerable support for complementary and alternative medicine/traditional medicine but also significant variation in usage of and perceptions of local traditional medicines. More research needs to be done to explore the social processes underlying this variation in cancer patients' preferences for particular traditional medicines.

    Oxcarbazepine is an anti-epileptic drug, which is almost completely metabolized by cytosolic enzymes in the liver to the active 10-monohyroxy metabolite (MHD) following oral administration. The pharmacokinetic (PK) profiles of MHD were evaluated in pediatric epileptic patients and a possible ethnic difference in PK of MHD between Japanese and non-Japanese pediatric patients was assessed. A non-linear mixed effect modeling approach was used to determine the PK of MHD. A one-compartment population model with first-order absorption appropriately described the PK of MHD. No clinically relevant differences were found for using body surface area or weight to explain between-patient variability, therefore the final model included the effects of body weight on apparent clearance (CL/F) and apparent volume of distribution (V/F) of MHD, and in addition, the effect of 3 concomitant anti-epileptic drugs (carbamazepine, phenobarbital and phenytoin) on CL/F of MHD. Inclusion of ethnicity as a covariate in the final model, concluded no ethnic difference with respect to CL/F of MHD between Japanese and non-Japanese patients. Hence, oxcarbazepine can be generally applied using the same dosage and administration for the treatment of partial onset seizures in pediatric patients, regardless of ethnicity.

  5. Kidney-differentiated cells derived from Lowe Syndrome patient's iPSCs show ciliogenesis defects and Six2 retention at the Golgi complex.

    Directory of Open Access Journals (Sweden)

    Full Text Available Lowe syndrome is an X-linked condition characterized by congenital cataracts, neurological abnormalities and kidney malfunction. This lethal disease is caused by mutations in the OCRL1 gene, which encodes for the phosphatidylinositol 5-phosphatase Ocrl1. While in the past decade we witnessed substantial progress in the identification and characterization of LS patient cellular phenotypes, many of these studies have been performed in knocked-down cell lines or patient's cells from accessible cell types such as skin fibroblasts, and not from the organs affected. This is partially due to the limited accessibility of patient cells from eyes, brain and kidneys. Here we report the preparation of induced pluripotent stem cells (iPSCs from patient skin fibroblasts and their reprogramming into kidney cells. These reprogrammed kidney cells displayed primary cilia assembly defects similar to those described previously in cell lines. Additionally, the transcription factor and cap mesenchyme marker Six2 was substantially retained in the Golgi complex and the functional nuclear-localized fraction was reduced. These results were confirmed using different batches of differentiated cells from different iPSC colonies and by the use of the human proximal tubule kidney cell line HK2. Indeed, OCRL1 KO led to both ciliogenesis defects and Six2 retention in the Golgi complex. In agreement with Six2's role in the suppression of ductal kidney lineages, cells from this pedigree were over-represented among patient kidney-reprogrammed cells. We speculate that this diminished efficacy to produce cap mesenchyme cells would cause LS patients to have difficulties in replenishing senescent or damaged cells derived from this lineage, particularly proximal tubule cells, leading to pathological scenarios such as tubular atrophy.

    People living in Japan were affected in various ways after the Great East Japan earthquake of March 11, 2011. A 52-year-old female asthma patient not directly affected by the disaster experienced a decrease in peak expiratory flow (PEF) immediately after the earthquake. Despite increasing the inhaled and oral corticosteroid doses, her PEF did not recover. One month later, her PEF level abruptly returned to normal with minimal medications, which were previously ineffective, and the asthma-related symptoms vanished. The stabilization of her state of mind and actual social state seemed to be a part of the reason for the patient's recovery.

    The goal of this meta-analysis was to quantitatively summarize the evidence available on the differences in grey matter volume between lithium-treated and lithium-free bipolar patients. A systematic search was conducted in Cochrane Central, Embase, MEDLINE, and PsycINFO databases for original peer-reviewed journal articles that reported on global grey matter volume in lithium-medicated and lithium-free bipolar patients. Standard mean difference and Hedges' g were used to calculate effect size in a random-effects model. Risk of publication bias was assessed using Egger's test and quality of evidence was assessed using standard criteria. There were 15 studies with a total of 854 patients (368 lithium-medicated, 486 lithium-free) included in the meta-analysis. Global grey matter volume was significantly larger in lithium-treated bipolar patients compared to lithium-free patients (SMD: 0.17, 95% CI: 0.01-0.33; z = 2.11, p = 0.035). Additionally, there was a difference in global grey matter volume between groups in studies that employed semi-automated segmentation methods (SMD: 0.66, 95% CI: 0.01-1.31; z = 1.99, p = 0.047), but no significant difference in studies that used fully-automated segmentation. No publication bias was detected (bias coefficient = - 0.65, p = 0.46). Variability in imaging methods and lack of high-quality evidence limits the interpretation of the findings. Results suggest that lithium-treated patients have a greater global grey matter volume than those who were lithium-free. Further study of the relationship between lithium and grey matter volume may elucidate the therapeutic potential of lithium in conditions characterized by abnormal changes in brain structure.

    Severe neurological symptoms in Shiga toxin-producing Escherichia coli infection associated hemolytic-uremic syndrome (STEC-HUS) are often accompanied by none or only mild alterations of cerebral magnetic resonance imaging (MRI). This study aims to analyze if quantitative MRI is able to reveal cerebral pathological alterations invisible for conventional MRI. In nine patients with STEC-HUS associated severe neurological symptoms but inconspicuous cerebral MRI findings maps of the parameters T2 relaxation time, relative proton density (PD), apparent diffusion coefficient (ADC), and fractional anisotropy (FA) were generated. Quantitative values of these parameters were measured at the basal ganglia, thalamus, and white matter of the frontal and parietal lobe and compared to those of nine age- and sex-matched controls. Significant T2 prolongation (p < 0.01) was found in the basal ganglia of all patients compared to controls. PD and ADC were not significantly altered. A significant reduction of FA in patients was seen at caput nuclei caudati (p < 0.01). Prolonged T2 relaxation time indicates cerebral microstructural damages in these patients despite their inconspicuous MRI findings. T2 relaxometry could be used as a complementary tool for the assessment of metabolic-toxic brain syndromes. (orig.)

    We have previously published a randomised controlled study of the efficacy of cryotherapy in preventing acute oral mucositis after high-dose chemotherapy for stem cell transplantation. The present study is a 5-year follow-up safety study of survival in these patients. In the previously published study oral cryotherapy (cooling of the oral cavity) during high-dose chemotherapy significantly reduced mucositis grade and opiate use in the treated group. All patients were followed up for at least 5 years with regard to relapse and death rates. Baseline data, transplant complications and mucositis data were compared. Significantly more patients (25/39) who received oral cryotherapy were alive after 5 years compared to 15/39 in the control group (P= 0.025). Relapse rates were similar. The only baseline difference was a lower proportion of patients in complete remission at transplantation in the control group (6 vs. 13, P= 0.047). This 5-year follow-up study gave no support for safety concerns with cryotherapy. © 2012 Blackwell Publishing Ltd.

    To investigate what factors influence patient global health assessment (PtGlobal), and how those factors and the reliability of PtGlobal affect the rate, reliability, and validity of recently published American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) rheumatoid arthritis (RA) remission criteria when used in clinical practice. We examined consecutive patients with RA in clinical practice and identified 77 who met ACR/EULAR joint criteria for remission (≤ 1 swollen joint and ≤ 1 tender joint). We evaluated factors associated with a PtGlobal > 1, because a PtGlobal ≤ 1 defined ACR/EULAR remission in this group of patients who had already met ACR/EULAR joint criteria. Of the 77 patients examined, only 17 (22.1%) had PtGlobal ≤ 1 and thus fully satisfied ACR/EULAR criteria. A large proportion of patients not in remission by ACR/EULAR criteria had high PtGlobal related to noninflammatory issues, including low back pain, fatigue, and functional limitations, and a number of patients clustered in the range of PtGlobal > 1 and ≤ 2. However, the minimal detectable difference for PtGlobal was 2.3. In addition, compared with a PtGlobal severity score, a PtGlobal activity score was 3.3% less likely to be abnormal (> 1). Noninflammatory factors contribute to the level of PtGlobal and result in the exclusion of many patients who would otherwise be in "true" remission according to the ACR/EULAR definition. Reliability problems associated with PtGlobal can also result in misclassification, and may explain the observation of low longterm remission rates in RA. As currently constituted, the use of the ACR/EULAR remission criteria in clinical practice appears to be problematic.

    Purpose: Pencil beam (PB) and collapsed cone convolution (CCC) dose calculation algorithms differ significantly when used in the thorax. However, such differences have seldom been previously directly correlated with outcomes of lung stereotactic ablative body radiation (SABR). Methods and Materials: Data for 201 non-small cell lung cancer patients treated with SABR were analyzed retrospectively. All patients were treated with 50 Gy in 5 fractions of 10 Gy each. The radiation prescription mandated that 95% of the planning target volume (PTV) receive the prescribed dose. One hundred sixteen patients were planned with BrainLab treatment planning software (TPS) with the PB algorithm and treated on a Novalis unit. The other 85 were planned on the Pinnacle TPS with the CCC algorithm and treated on a Varian linac. Treatment planning objectives were numerically identical for both groups. The median follow-up times were 24 and 17 months for the PB and CCC groups, respectively. The primary endpoint was local/marginal control of the irradiated lesion. Gray's competing risk method was used to determine the statistical differences in local/marginal control rates between the PB and CCC groups. Results: Twenty-five patients planned with PB and 4 patients planned with the CCC algorithms to the same nominal doses experienced local recurrence. There was a statistically significant difference in recurrence rates between the PB and CCC groups (hazard ratio 3.4 [95% confidence interval: 1.18-9.83], Gray's test P=.019). The differences (Δ) between the 2 algorithms for target coverage were as follows: ΔD99{sub GITV} = 7.4 Gy, ΔD99{sub PTV} = 10.4 Gy, ΔV90{sub GITV} = 13.7%, ΔV90{sub PTV} = 37.6%, ΔD95{sub PTV} = 9.8 Gy, and ΔD{sub ISO} = 3.4 Gy. GITV = gross internal tumor volume. Conclusions: Local control in patients receiving who were planned to the same nominal dose with PB and CCC algorithms were statistically significantly different.

    Noninvasive indices based on Doppler echocardiography are increasingly used in clinical cardiovascular research to evaluate left ventricular global systolic chamber function. Our objectives were to clinically validate ultrasound-based methods of global systolic chamber function to account for differences between patients in conditions of abnormal load, and to assess their sensitivity to load confounders. Twenty-seven patients (8 dilated cardiomyopathy, 10 normal ejection fraction, and 9 end-stage liver disease) underwent simultaneous echocardiography and left heart catheterization with pressure-conductance instrumentation. The reference index, maximal elastance (Emax), was calculated from pressure-volume loop data obtained during acute inferior vena cava occlusion. A wide range of values were observed for left ventricular systolic chamber function (Emax: 2.8±1.0 mm Hg/mL), preload, and afterload. Among the noninvasive indices tested, the peak ejection intraventricular pressure difference showed the best correlation with Emax (R=0.75). A significant but weaker correlation with Emax was observed for ejection fraction (R=0.41), midwall fractional shortening (R=0.51), global circumferential strain (R=-0.53), and strain rate (R=-0.46). Longitudinal strain and strain rate failed to correlate with Emax, as did noninvasive single-beat estimations of this index. Principal component and multiple regression analyses demonstrated that peak ejection intraventricular pressure difference was less sensitive to load, whereas ejection fraction and longitudinal strain and strain rate were heavily influenced by afterload. Current ultrasound methods have limited accuracy to characterize global left ventricular systolic chamber function in a given patient. The Doppler-derived peak ejection intraventricular pressure difference should be preferred for this purpose because it best correlates with the reference index and is more robust in conditions of abnormal load.

    Full Text Available Abstract Background Family function may have an influence on the mental health deterioration of the caregivers of dependent family members and it could have a varying importance on the care of dependents. Little attention has been paid to the preparation of minor stroke survivors for the recovery trajectory or the spouse for the caregiving role. Therefore, this study protocol intends to analyze the influence of family function on the protection of patients with stroke sequels needing physiotherapy in the family environment. Methods/Design This is an analytical observational design, prospective cohort study and using a qualitative methodology by means of data collected in the “interviews of life”. The study will be carried out by the Rehabilitation Service at Hospital of Elda in the Valencia Community. All patients that have been diagnosed with stroke and need physiotherapy treatment, having a dependency grade assigned and consent to participate in the study, will undergo a monitoring of one year in order to assess the predictive factors depending on the dependence of the people affected. Discussion Our research aims to analyze the perception of caregivers, their difficulties to work, and the influence of family function. Moreover, it aims to register the perception of the patients with stroke sequel over the care received and whether they feel protected in their family environment.

    To assess patient-physician discordance in global assessment of disease activity in early axial spondyloarthritis (axSpA) over time and determinants of discordance. DESIR (Devenir des Spondyloarthropathies Indifférenciées Récentes) is a French, multicentre, longitudinal cohort of patients with early inflammatory back pain suggestive of axSpA. Patient global assessment (PGA) and physician global assessment (PhGA) were rated with a 0-10 numerical rating scale, every 6 months during 2 years then at 3 years. Discordance was defined by the absolute difference |PGA-PhGA|≥3 (range 0-10) and was analysed at each visit. Determinants of (PGA-PhGA) were assessed at the visit level by a generalised linear mixed model. A total of 702 patients were analysed at baseline (401 with complete data over 3 years): mean age 33.8±8.6 years, 379 (54.0%) female, mean symptom duration 18.1±10.5 months. Mean PGA values were always higher than mean PhGA values with a mean absolute difference of 1.8 points. At baseline, 202 (28.8%) patients had discordance mainly by PGA>PhGA; over 3 years the frequency of discordance was stable (range 25.5-28.8%).

    Nonclinical studies have suggested that oxidative damage, caspase-mediated apoptosis, and inducible nitric oxide synthase levels may be involved in the pathogenesis of colistin (CST)-associated acute renal failure. MIN inhibits caspase 1, caspase 3, and inducible nitric oxide synthase, leading to the hypothesis that coadministration of CST with MIN (CST-MIN) may reduce the incidence of acute renal failure as well as produce additive or synergistic antimicrobial effects. A multicenter retrospective cohort study was conducted using the Premier Research database to examine the impact of CST-MIN on acute renal failure. Inclusion criteria were as follows: age of ≥18 years, intensive care unit admission at CST initiation, primary International Classification of Diseases 9 (ICD-9) diagnosis of pneumonia or sepsis, nondialysis at hospital admission, and discharge between January 2010 and December 2015. ICD-9 code 584.XX or ICD-10 code N17 was used to define acute renal failure. Baseline comparisons, 1:8 propensity score matching, and confirmatory logistic regression analyses were conducted. In total, 4,817 patients received CST and met inclusion criteria; 93 received CST-MIN. Unadjusted frequency of acute renal failure was significantly lower in patients receiving CST-MIN than CST (11.8% versus 23.7%, P = 0.007). Similar results were seen in propensity score matching (12.0% versus 22.3%, P = 0.031) and logistic regression analyses (odds ratio of 0.403, P = 0.006). Mortalities and 30-day readmission rates were similar between groups. The acute renal failure rate was not impacted by prevalence of baseline renal disease. CST-MIN in critically ill patients may reduce CST-associated acute renal failure. Further evaluation of this combination in prospective clinical studies is warranted. Copyright © 2017 Lodise et al.

    Transgender, gender-variant, and intersex (trans) people have decreased access to care and poorer health outcomes compared with the general population. Little has been studied and documented about such patients' emergency department (ED) experiences and barriers to care. Using survey and qualitative research methods, this study aims to identify specific areas for improvement and generate testable hypotheses about the barriers and challenges for trans individuals needing acute care. A survey and 4 focus groups were conducted with trans individuals older than 18 years who had been to an ED in the last 5 years. Participants were recruited by trans e-mail listservs; outreach to local trans organizations; and lesbian, gay, bisexual, and transgender periodical advertisements. The interview guide was reviewed by qualitative research and trans health content experts. Deidentified participant demographic information was collected with a standardized instrument. All discussions were captured on digital audio recorders and professionally transcribed. Interview coding and thematic analysis were conducted with a grounded theory approach. Among 32 participants, 71.9% were male identified and 78.1% were white. Nearly half (43.8%) reported avoiding the ED when they needed acute care. The factors that had the greatest influence on ED avoidance were fear of discrimination, length of wait, and negative previous experiences. There were 4 overarching discussion themes: system structure, care competency, discrimination and trauma, and avoidance of emergency care. Improvement recommendations focused on staff and provider training about gender and trans health, assurance of private gender identity disclosure, and accurate capture of sex, gender, and sexual orientation information in the electronic medical record. Efforts to improve trans ED experiences should focus on provider competency and communication training, electronic medical record modifications, and assurance of private means

    Accurate identification and management of malnutrition is essential so that patient outcomes can be improved and resources used efficaciously. In malnourished older adults admitted to rehabilitation: 1) report the prevalence, health and aged care use, and mortality of malnourished older adults; 2) determine and compare the criterion (concurrent and predictive) validity of the Scored Patient-Generated Subjective Global Assessment (PG-SGA) and the Mini Nutritional Assessment (MNA) in diagnosing malnutrition; and 3) identify the Scored PG-SGA score cut-off value associated with malnutrition. Observational, prospective cohort. Participants were 57 older adults (65 years and older; mean±standard deviation age=79.1±7.3 years) from two rural rehabilitation units in New South Wales, Australia. Scored PG-SGA; MNA; and the International Statistical Classification of Diseases and Health Related Problems, 10th revision, Australian Modification (ICD-10-AM) classification of malnutrition were compared to establish concurrent validity and report malnutrition prevalence. Length of stay, discharge location, rehospitalization, admission to a residential aged care facility, and mortality were measured to report health-related outcomes and to establish predictive validity. Malnutrition prevalence varied according to assessment tool (ICD-10-AM: 46%; Scored PG-SGA: 53%; MNA: 28%). Using the ICD-10-AM as the reference standard, the Scored PG-SGA ratings (sensitivity 100%, specificity 87%) and score (sensitivity 92%, specificity 84%, ROC AUC [receiver operating characteristics area under the curve]=0.910±0.038) showed strong concurrent validity, and the MNA had moderate concurrent validity (sensitivity 58%, specificity 97%, receiver operating characteristics area under the curve=0.854±0.052). The Scored PG-SGA rating, Scored PG-SGA score, and MNA showed good predictive validity. Malnutrition can increase the risk of longer rehospitalization length of stay, admission to a residential

    To investigate whether multiple sclerosis (MS) patients with and without cerebrospinal fluid (CSF) oligoclonal immunoglobulin G bands (OCB) differ in brain atrophy. Twenty-eight OCB-negative and thirty-five OCB-positive patients were included. Larger volumes of total CSF and white matter (WM) lesions; smaller gray matter (GM) volume in the basal ganglia, diencephalon, cerebellum, and hippocampus; and smaller WM volume in corpus callosum, periventricular-deep WM, brainstem, and cerebellum, were observed in OCB-positives. OCB-negative patients, known to differ genetically from OCB-positives, are characterized by less global and regional brain atrophy. This finding supports the notion that OCB-negative MS patients may represent a clinically relevant MS subgroup. Copyright © 2014 Elsevier B.V. All rights reserved.

    In a previous study, it was shown that placing a subject with chronic diabetic ulcers in a warm room prior to the use of electrical stimulation dramatically increased the healing rate. However, global heating is impractical in many therapeutic environments, and therefore in the present investigation the effect of global heat versus using a local heat source to warm the wound was investigated. Twenty-nine male and female subjects participated in a series of experiments to determine the healing associated with electrical stimulation with the application of local heat through a heat lamp compared to global heating of the subject in a warm room. Treatment consisted of biphasic electrical stimulation at currents at 20 mA for 30 min three times per week for 4 weeks in either a 32 degrees C room or, with the application of local heat, to raise skin temperature to 37 degrees C. Skin blood flow was measured by a laser Doppler imager. Blood flow increased with either local or global heating. During electrical stimulation, blood flow almost doubled on the outside and on the edge of the wound with a smaller increase in the center of the wound. However, the largest increase in blood flow was in the subjects exposed to global heating. Further, healing rates, while insignificant for subjects who did not receive electrical stimulation, showed 74.5 +/- 23.4% healing with global heat and 55.3 +/- 31.1% healing with local heat in 1 month; controls actually had a worsening of their wounds. The best healing modality was global heat. However, there was still a significant advantage in healing with local heat.

    Full Text Available Abstract Background Previous reports have suggested that the VEGF receptor neuropilin-1 (NRP-1 is expressed in a singly dispersed subpopulation of cells in the normal colonic epithelium, but that expression becomes dysregulated during colorectal carcinogenesis, with higher levels in tumour suggestive of a poor prognosis. We noted that the spatial distribution and morphology if NRP-1 expressing cells resembles that of enteroendocrine cells (EEC which are altered in response to disease state including cancer and irritable bowel syndrome (IBS. We have shown that NRP-1 is down-regulated by butyrate in colon cancer cell lines in vitro and we hypothesized that butyrate produced in the lumen would have an analogous effect on the colon mucosa in vivo. Therefore we sought to investigate whether NRP-1 is expressed in EEC and how NRP-1 and EEC respond to butyrate and other short-chain fatty acids (SCFA - principally acetate and propionate. Additionally we sought to assess whether there is a field effect around adenomas. Methodology Biopsies were collected at the mid-sigmoid, at the adenoma and at the contralateral wall (field of 28 subjects during endoscopy. Samples were fixed for IHC and stained for either NRP-1 or for chromogranin A (CgA, a marker of EEC. Stool sampling was undertaken to assess individuals' butyrate, acetate and propionate levels. Result NRP-1 expression was inversely related to SCFA concentration at the colon landmark (mid-sigmoid, but expression was lower and not related to SCFA concentration at the field. Likewise CgA+ cell number was also inversely related to SCFA at the landmark, but was lower and unresponsive at the field. Crypt cellularity was unaltered by field effect. A colocalisation analysis showed only a small subset of NRP-1 localised with CgA. Adenomas showed extensive, weaker staining for NRP-1 which contrastingly correlated positively with butyrate level. Field effects cause this relationship to be lost. Adenoma tissue

    We isolated and characterized a peptide fragment corresponding to amino acid sequence 14-28 of human osteocalcin in urine from Paget's disease, and developed a polyclonal antibody reactive to this peptide in urine. We used this antibody to measure urinary fragments of osteocalcin and compared to efficacy of the urinary osteocalcin assay with a serum osteocalcin (sOC) assay (ELISA-Osteo, Cis-Bio International) to monitor the short-term changes in bone turnover in response to alendronate treatment. The synthetic peptide-based urinary osteocalcin (uOC) radioimmunoassay (RIA) showed an analytical sensitivity of 6.25 ng/mL, standard curve range of 3.12-400 ng/mL, and mean intra- (n = 20) and interassay (n = 30) coefficient of variation (CV) of sALP) (Alkphose-B, Metra Biosystems) in serum samples. The percent change data obtained between baseline and 30 days (n = 18) posttreatment suggested a rapid decline in uOC concentration (-27%, p sALP (-3.4%, p = 0.689), two specific markers of bone formation. As expected, due to the coupling of bone formation and bone resorption, the concentration of all markers showed a 30%-45% decline compared with baseline values after 90 days (n = 16) of treatment. Correlation of markers after a 30 day treatment with alendronate revealed a higher correlation (r = 0.61, p sALP (r = -0.14, p = 0.295) with uNTx. Similarly, correlation coefficients with r values between 0.48 and 0.55 (p < 0.05) were observed between uOC, sNTx, and sCTx, whereas no significant correlation was observed between sOC and sNTx or sCTx. These results provide indirect evidence that fragments measured by the urine assay probably originated from bone resorption, and suggest that the uOC assay could be used to assess short-term changes in bone metabolism with regard to osteocalcin.

    2014-12-01

    Obesity is an important disease with a high prevalence in cats. Because obesity is related to several other diseases, it is important to identify the population at risk. Several risk factors for obesity have been described in the literature. A higher incidence of obesity in certain cat breeds has been suggested. The aim of this study was to determine whether obesity occurs more often in certain breeds. The second aim was to relate the increased prevalence of obesity in certain breeds to the official standards of that breed. To this end, 268 cats of 22 different breeds investigated by determining their body condition score (BCS) on a nine-point scale by inspection and palpation, at two different cat shows. Overall, 45.5% of the show cats had a BCS > 5, and 4.5% of the show cats had a BCS > 7. There were significant differences between breeds, which could be related to the breed standards. Most overweight and obese cats were in the neutered group. It warrants firm discussions with breeders and cat show judges to come to different interpretations of the standards in order to prevent overweight conditions in certain breeds from being the standard of beauty. Neutering predisposes for obesity and requires early nutritional intervention to prevent obese conditions. Journal of Animal Physiology and Animal Nutrition © 2014 Blackwell Verlag GmbH.

    Arturo Vargas Bustamante

    2014-06-01

    Full Text Available Neil Lunt and Russel Mannion provide an overview of the current state of the medical tourism literature and propose areas for future research in health policy and management. The authors also identify the main unanswered questions in this field ranging from the real size of the medical tourism market to the particular health profiles of transnational patients. In addition, they highlight unexplored areas of research from health economics, ethics, policy and management perspectives. To this very insightful editorial I would add the international trade perspective. While globalization has permeated labor and capital, services such as healthcare are still highly regulated by governments, constrained to regional or national borders and protected by organized interests. Heterogeneity of healthcare regulations and lack of cross-country reciprocity agreements act as barriers to the development of more widespread and dynamic medical tourism markets. To picture these barriers to transnational health services I use evidence from North America, identifying different “pull and push factors” for medical tourist in this region, discussing how economic integration and healthcare reform might shift the incentives to utilize healthcare abroad.

    Full Text Available Background. The internet offers a potential for improving patient knowledge, and e-mail may be used in patient communication with providers. However, barriers to internet and e-mail use, such as low health literacy and cognitive impairment, may prevent patients from using technological resources. Purpose. We investigated whether health literacy, heart failure knowledge, and cognitive function were related to internet and e-mail use in older adults with heart failure (HF. Methods. Older adults (N=119 with heart failure (69.84±9.09 years completed measures of health literacy, heart failure knowledge, cognitive functioning, and internet use in a cross-sectional study. Results. Internet and e-mail use were reported in 78.2% and 71.4% of this sample of patients with HF, respectively. Controlling for age and education, logistic regression analyses indicated that higher health literacy predicted e-mail (P<.05 but not internet use. Global cognitive function predicted e-mail (P<.05 but not internet use. Only 45% used the Internet to obtain information on HF and internet use was not associated with greater HF knowledge. Conclusions. The majority of HF patients use the internet and e-mail, but poor health literacy and cognitive impairment may prevent some patients from accessing these resources. Future studies that examine specific internet and email interventions to increase HF knowledge are needed.

    The global popularity of cosmetic surgery, combined with mass media attention on medical consumerism, has resulted in misinformation that may have negatively affected the "collective image" of aesthetic practitioners. The authors assess patients' perceptions of cosmetic surgery and analyze their decision-making processes. During a 2-year period, 250 consecutive patients presenting to either of 2 public hospitals for cosmetic surgery treatment were asked to complete a 7-item questionnaire evaluating their knowledge of opinions about, and referring practices for, aesthetic procedures. Patients undergoing oncologic, postbariatric, or reconstructive procedures were not included in the study. After exclusion of 71 cases for refusal or incompletion, 179 questionnaires were retained and analyzed (from 162 women and 17 men). Overall, repair (70.4%), comfort (45.3%), and health (40.8%) were the words most frequently associated with cosmetic surgery. Quality of preoperative information (69.3%), patient-physician relationship (65.4%), and results seen in relatives/friends (46.3%) were the most important criteria for selecting a cosmetic surgeon. Moreover, 82.7% of patients knew the difference between cosmetic surgery and cosmetic medicine. Although potential patients appear to be more educated about cosmetic surgery than they were several years ago, misinformation still persists. As physicians, we must be responsible for disseminating accurate education and strengthening our collaboration with general practitioners to improve not only our results but also the accuracy of information in the mass media.

    To determine whether elements of a standard nutritional screening assessment are independently prognostic of survival in patients with advanced cancer. A prospective nested cohort of patients with metastatic cancer were accrued from different units of a Regional Palliative Care Program. Patients completed a nutritional screen on admission. Data included age, sex, cancer site, height, weight history, dietary intake, 13 nutrition impact symptoms, and patient- and physician-reported performance status (PS). Univariate and multivariate survival analyses were conducted. Concordance statistics (c-statistics) were used to test the predictive accuracy of models based on training and validation sets; a c-statistic of 0.5 indicates the model predicts the outcome as well as chance; perfect prediction has a c-statistic of 1.0. A training set of patients in palliative home care (n = 1,164) was used to identify prognostic variables. Primary disease site, PS, short-term weight change (either gain or loss), dietary intake, and dysphagia predicted survival in multivariate analysis (P statistics between predicted and observed responses for survival in the training set (0.90) and validation set (0.88; n = 603). The addition of weight change, dietary intake, and dysphagia did not further improve the c-statistic of the model. The c-statistic was also not altered by substituting physician-rated palliative PS for patient-reported PS. We demonstrate a high probability of concordance between predicted and observed survival for patients in distinct palliative care settings (home care, tertiary inpatient, ambulatory outpatient) based on patient-reported information.

We knew that a major obstacle to librarians using the research literature was that they did not have access to the research literature. Although Su and I are both academic librarians who can access a wide variety of library and information literature from our institutions, we belong to a profession where not everyone has equal access to the research in our field. Without such access to our own body of literature, how can we ever hope for practitioners to use research evidence in their decision making? It would have been contradictory to the principles of evidence based library and information practice to do otherwise.One of the specific groups we thought could use such an open access venue for discovering research literature was school librarians. School librarians are often isolated and lacking access to the research literature that may help them prove to stakeholders the importance of their libraries and their role within schools. Certainly, school libraries have been in decline and the use of evidence to show value is needed. As Ken Haycock noted in his 2003 report, The Crisis in Canada’s School Libraries: The Case for Reform and Reinvestment, “Across the country, teacher-librarians are losing their jobs or being reassigned. Collections are becoming depleted owing to budget cuts. Some principals believe that in the age of the Internet and the classroom workstation, the school library is an artifact” (9. Within this context, school librarians are looking to our research literature for evidence of the impact that school library programs have on learning outcomes and student success. They are integrating that evidence into their practice, and reflecting upon what can be improved locally. They are focusing on students and showing the impact of school libraries and

    The aim of this study was to correlate patients with gastrointestinal cancer, classified according to different stages of cancer cachexia (SCC) as proposed by Fearon, with nutritional assessment tools such as PG-SGA, phase angle (PA), and handgrip strength. One hundred one patients with a mean age of 61.8 ± 12.8 yr, with 58.4% being men were included. 32.6% were malnourished according to the body mass index (BMI). A severe or moderate malnutrition had been diagnosed in 63.3% when assessed using the PG-SGA, 60.4% had decreased handgrip strength, and 57.4% had lower grades of PA. Among the patients in the study, 26% did not have cachexia, 11% had precachexia, 56% cachexia, and 8% refractory cachexia. The PG-SGA, PA, and handgrip strength were associated with cachexia (P ≤ 0.001). An increased risk of death was found in patients with cachexia [RR: 9.1; confidence interval (CI) 95%: 0.1-90.2, P = 0.039], refractory cachexia (RR: 69.4, CI 95%: 4.5-1073.8, P = 0.002), and increased serum C-reactive protein (CRP) levels (P cachexia or refractory cachexia in the first nutritional assessment. Nutritional risk, as determined by PG-SGA, was correlated with PA and handgrip strength. High CRP levels, cachexia, and refractory cachexia were prognostic factors for cancer patients.

  4. Patients Without Borders: Using Telehealth to Provide an International Experience in Veterinary Global Health for Veterinary Students.

    Mazan, Melissa R; Kay, Gigi; Souhail, Mohammed Larbi; Bubeck, Kirstin; Jenei, Thomas; Merriam, Jay

    There is an increasing need to produce veterinarians with knowledge and critical thinking skills that will allow them to participate in veterinary global health equity delivery, particularly in the developing world, where many people remain dependent on animal-based agriculture for a living. This need for veterinarians trained in global health is reflected by the demand among students for greater exposure and education. At the same time, many students are held back from on-site training in global health due to constraints of cost, time, or family obligations. The purpose of this article is to describe the use of a telemedicine approach to educating veterinary students at Tufts Cummings School of Veterinary Medicine. This approach simultaneously provides expert consultation and support for a pro bono hospital in the developing world. The development of a telemedicine teaching service is discussed, from initial ad hoc email consultation among friends and associates to a more formal use of store-and-forward delivery of data along with real-time videoconferencing on a regular basis, termed tele-rounds. The practicalities of data delivery and exchange and best use of available bandwidth are also discussed, as this very mundane information is critical to efficient and useful tele-rounds. Students are able to participate in discussion of cases that they would never see in their usual clinical sphere and to become familiar with diagnostic and treatment approaches to these cases. By having the patient "virtually" brought to us, tele-rounds also decrease the usual carbon footprint of global health delivery.

    Disability from mental health (MH) symptoms impairs workers' functioning. Most of what is known about the MH of workers relates to their experiences after intervention or work absence. To profile the clinical symptoms, self-reported absenteeism and presenteeism and treatment response of workers with MH symptoms at the point of accessing MH care and compare the characteristics of patients referred with or without problems related to work. Analysis of 11 years of patient data collected in a Shared Mental Health Care (SMHC) clinic referred within a primary care setting in Ontario, Canada. Multiple regression with MH disorders was used to predict absenteeism and presenteeism. Absenteeism and presenteeism were assessed using the 12-item self-administered version of the WHO-DAS 2. Symptom profiles were assessed with the Patient Health Questionnaire (PHQ). Some psychiatric disorders (depression, somatization, anxiety) contributed more to predicting absenteeism and presenteeism than others. Patients referred with work-related problems differed from the general SMHC population in terms of sex and type and number of symptoms. Treatment response was good in both groups after a mean of three treatment visits. Patients with work-related mental health complaints formed a distinct clinical group that benefitted equally from the intervention(s) provided by SMHC.

    Scale-up of HIV treatment services may have contributed to an increase in functional health facilities available in resource-limited settings and an increase in patient use of facilities and retention in care. As more patients are reached with medicines, monitoring patient safety is increasingly important. Limited data from resource-limited settings suggest that medication error and antiretroviral drug-drug interactions may pose a significant risk to patient safety. Commonly cited causes of medication error in the developed world include the speed and complexity of the medication use cycle combined with inadequate systems and processes. In resource-limited settings, specific factors may contribute, such as inadequate human resources and high disease burden. Management of drug-drug interactions may be complicated by limited access to alternative medicines or laboratory monitoring. Improving patient safety by addressing the issue of antiretroviral drug-drug interactions has the potential not just to improve healthcare for individuals, but also to strengthen health systems and improve vital communication among healthcare providers and with regulatory agencies.

    Family caregivers of cancer patients often suffer from impaired quality of life (QOL) due to stress arising from the responsibility of caregiving. Most research on such QOL impairments was conducted in Western populations. Thus, this exploratory study sought to (a) examine the QOL levels of family caregivers of cancer patients in an Asian population in Singapore, in relation to caregivers from other countries within and outside of Asia; and (b) investigate the association between sociodemographic factors and QOL impairments in family caregivers in Singapore. A total of 258 family caregivers of cancer patients who were receiving outpatient treatment completed the Caregiver Quality of Life Index-Cancer (CQOLC) and a sociodemographic survey. We compared the published CQOLC total scores from Turkey, Iran, Taiwan, South Korea, the United Kingdom, the United States and Canada with the Singapore dataset and examined the demographic relationships. Caregivers in Singapore and Asia had lower CQOLC total scores than their Western counterparts. Caregivers who were male, of Chinese ethnicity, had parental relationships with their care recipient, or cared for advanced-stage cancer patients were found to have impaired QOL. The findings of this study highlight possible areas in which support can be provided for family caregivers of cancer patients, and underscore the need to reconcile cultural diversity, values, societal expectations and demographic characteristics in Singapore.

    Although coronary angiography defines regions of potential ischemia in patients with coronary-artery disease, accurate assessment of the presence and functional importance of ischemia requires appraisal of regional and global left ventricular function during stress. To perform such assessment, we developed a noninvasive real-time radionuclide cineangiographic procedure permitting continuous monitoring and analysis of left ventricular function during exercise. In 11 patients with coronary disease who had normal regional and global ventricular function at rest, new regions of dysfunction developed during exercise (P less than 0.001), and in 10, global ejection fraction dropped 7 to 47 percent. Fourteen age-matched normal subjects were studied; during exercise none had regional dysfunction, and each increased global ejection fraction (average increase, 23 +- 3 percent [+-S.E.], P less than 0.001 as compared with patients with coronary disease). Radionuclide cineangiography during exercise permits accurate assessment of the presence and functional severity of ischemic heart disease

    The aims of this study were to describe the current status of intensive care unit (ICU) visiting hours policies internationally and to explore the influence of ICUs' open visiting policies on patients', visitors', and staff perceptions, as well as on patients' outcomes. A review of the literature was done through MEDLINE, EMBASE, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases. The following keywords were searched: "visiting," "hours," "ICU," "policy," and "intensive care unit." Inclusion criteria for the review were original research paper, adult ICU, articles published in the last 10 years, English or Italian language, and available abstract. Twenty-nine original articles, mainly descriptive studies, were selected and retrieved. In international literature, there is a wide variability about open visiting policies in ICUs. The highest percentage of open ICUs is reported in Sweden (70%), whereas in Italy there is the lowest rate (1%). Visiting hours policies and number of allowed relatives are variable, from limits of short precise segments to 24 hours and usually 2 visitors. Open ICUs policy/guidelines acknowledge concerns with visitor hand washing to prevent the risk of infection transmission to patients. Patients, visitors, and staff seem to be inclined to support open ICU programs, although physicians are more inclined to the enhancement of visiting hours than nurses. The percentages of open ICUs are very different among countries. It can be due to local factors, cultural differences, and lack of legislation or hospital policy. There is a need for more studies about the impact of open ICUs programs on patients' mortality, length of stay, infections' risk, and the mental health of patients and their relatives.

    To evaluate whether the psychological state is related to the Boolean-based definition of patient global assessment (PGA) remission in patients with rheumatoid arthritis (RA). Patients with RA who met the criteria of swollen joint count (SJC) ≤ 1, tender joint count (TJC) ≤ 1 and C-reactive protein (CRP) ≤ 1 were divided into two groups, PGA remission group (PGA ≤ 1 cm) and non-remission group (PGA > 1 cm). Anxiety was evaluated utilizing the Hospital Anxiety and Depression Scale-Anxiety (HADS-A), while depression was evaluated with HADS-Depression (HADS-D) and the Center for Epidemiologic Studies Depression Scale (CES-D). Comparison analyses were done between the PGA remission and non-remission groups in HADS-A, HADS-D and CES-D. Seventy-eight patients met the criteria for SJC ≤ 1, TJC ≤ 1 and CRP ≤ 1. There were no significant differences between the PGA remission group (n = 45) and the non-remission group (n = 33) in age, sex, disease duration and Steinbrocker's class and stage. HADS-A, HADS-D and CES-D scores were significantly lower in the PGA remission group. Patients with RA who did not meet the PGA remission criteria despite good disease condition were in a poorer psychological state than those who satisfied the Boolean-based definition of clinical remission. Psychological support might be effective for improvement of PGA, resulting in the attainment of true remission.

    Full Text Available Introduction: Left ventricular remodeling is a relatively prevalent complication of acute myocardial infarction (AMI, and it is associated with higher rates of medical issues and mortality. Left ventricle ejection fraction (LVEF and wall motion score index (WMSI are unable to detect accurately minor lesions following AMI. Global longitudinal strain (GLS, which is obtained through 2D-speckle tracking echocardiography (2D-STE, provides an angle-dependent measurement by which the infarcted area can be assessed as a means of identifying potential dysfunction. The main objective of this study was to evaluate whether GLS could adequately predict LV remodeling in AMI patients. Methods: The MEDLINE database from database inception to May 6th, 2015, was searched for relevant keywords and the reference lists of systematic reviews and eligible studies were also screened. All studies involving patients with their first reported case of AMI were examined for GLS by 2D-STE and were evaluated for LV remodeling at a three-month follow-up point.  Four English-language prospective cohort studies were eligible for inclusion in this study.Result: A total of 291 AMI patients (mean age=57.92 years were investigated across four different studies. The main finding of this study was that the most reliable and consistent measurement for the purposes of predicting LV remodeling in AMI patients is GLS obtained at the time of discharge, especially in STEMI patients.Discussion: In addition to their poor reproducibility, inability to stratify risks, and inter-observer variability, compensatory hyperkinesis of intact myocytes and myocardial stunning after an AMI are among the main reasons why LVEF and WMSI may not be the most effective predictors of LV remodeling in AMI.Conclusion: GLS obtained by 2D-STE at the time of discharge could be used as a reliable predictor of LV remodeling in AMI patients.

GARDIAN prospectively enrolled 23,708 patients undergoing routine gadobutrol-enhanced MRI/MRA for approved indications at 272 study centres in Europe, Asia, North America, and Africa and monitored for adverse events. Median gadobutrol dose was 0.11 mmol/kg body weight. The overall incidence of adverse drug reactions (ADRs) was 0.7 % (n = 170 patients), with similar incidences in patients with renal impairment or cardiac disease, from different geographic regions and in different gadobutrol dose groups. Patients at risk for contrast media reaction had an ADR incidence of 2.5 %. Five patients (0.02 %) experienced serious adverse events, four were drug-related. One patient experienced a fatal anaphylactoid shock, assessed to be related to injection of gadobutrol. The contrast quality of gadobutrol-enhanced images was rated by treating physicians as good or excellent in 97 % cases, with similar ratings in all patient subgroups and indications. The GARDIAN study shows that gadobutrol at the recommended dose is well tolerated across a large, diverse patient population. (orig.)

An observational, analytical, descriptive and retrospective study was conducted on 2013 clinical charts from an Internal Medicine Department in order to detect EA through the identification of 'triggers' (an event often related to an AE). The 'triggers' and AE were located by systematic review of clinical documentation. The AE were characterized after they were identified. A total of 149 AE were detected in 291 clinical charts during 2013, of which 75.3% were detected directly by the tool, while the rest were not associated with a trigger. The percentage of charts that had at least one AE was 35.4%. The most frequent AE found was pressure ulcer (12%), followed by delirium, constipation, nosocomial respiratory infection and altered level of consciousness by drugs. Almost half (47.6%) of the AE were related to drug use, and 32.2% of all AE were considered preventable. The tool demonstrated a sensitivity of 91.3% (95%CI: 88.9-93.2) and a specificity of 32.5% (95%CI: 29.9-35.1). It had a positive predictive value of 42.5% (95%CI: 40.1-45.1) and a negative predictive value of 87.1% (95%CI: 83.8-89.9). The tool used in this study is valid, useful and reproducible for the detection of AE. It also serves to determine rates of injury and to observe their progression over time. A high frequency of both AE and preventable events were observed in this study. Copyright © 2014 SECA. Published by Elsevier Espana. All rights reserved.

    The aim of the present study was to examine whether depression and anxiety disorder manifest different autonomic dysregulations using heart-rate variability (HRV) and heart rate (HR) measurements. HRV and HR were recorded both at rest and during task execution (random-number generation) in first-onset drug-naïve patients with major depressive disorder (MDD, n = 14) and generalized anxiety disorder (GAD, n = 11) as well as in healthy controls (n = 41). The patients showed no comorbidity of depression and anxiety disorder. GAD patients did not exhibit panic or phobic symptoms at the time of measurement. Following power spectrum analysis of HR trend, the high- (HF) and low-frequency (LF) components, the sum (LF + HF), and the LF/HF ratio were compared among the groups. In the MDD patients, as previously reported, HF was low and the LF/HF ratio was high during the initial-rest condition, and HF was less reactive to the task. In contrast, GAD patients showed significantly high HF, although autonomic reactivity was not impaired. The results indicate that baseline autonomic activity and its reactivity to behavioral changes are different between MDD and GAD in the early stage of illness. High parasympathetic tone in GAD may reflect responses of the parasympathetic system to anxiety. MDD is accompanied by an autonomic shift toward sympathetic activation and a reduced reactivity to task. © 2016 The Authors.

    Under the title ''MR Imaging in Patients with Cardiac Pacemakers and Implantable Cardioverter Defibrillators'', this issue of Roefo - simultaneously with the journal of the German Cardiac Society ''Der Kardiologe'' - presents a consensus paper of the German Roentgen Society and the German Cardiac Society [1] [2] that was jointly written by the authors in radiology and cardiology but does not exclusively address cardiac MRI. This publication relates to MR imaging of all regions of the body. In Germany and internationally the number of MRI examinations is increasing: 1,008,944 examinations were performed on patients receiving inpatient treatment in 2005 while 1,767,005 examinations were performed in 2013 (DRG hospitals). This development can be attributed to our aging population as well as to new indications for MRI including: Analyses of tissue composition and function, for example in the liver [3] [4] and the heart [5] [6]; multiparametric analyses of MR perfusion, e.g. in treated brain tumors [7]; new organs such as the lung [8]; dedicated examinations for intervention planning and operation monitoring [9] [10] [11]; as well as MRI-guided interventions [12] [13] [14] [15] [16]. Implants must always be considered in all of these MRI examinations even if the reason for the examination request is not related to an implant. The involvement of cardiology in this case is not based on the medical issue but rather on the type of implant. Expertise in cardiology is required when dealing with cardiac pacemakers (PM) and implantable cardioverter defibrillators (ICD).

    The Pan American Health Organization/World Health Organization (PAHO/WHO), founded in 1902, initiated a radiological health programme in the 1950s. Within this programme, there are currently three lines of work: (a) radiology services; (b) radiation safety; and (c) radiological emergencies. Radiology services deals with health services for diagnostic and interventional imaging, and for radiation therapy. Radiation safety studies the three types of exposures to both ionizing and non-ionizing radiation: occupational; medical; and public. Radiological emergencies involve radioactive waste management programmes and emergency plans. The radiological protection of patients is addressed in each of these areas: (a) when analysing the infrastructure of radiology services; and (b) when determining medical exposures; and (c) when investigating overexposures in interventional or therapeutic procedures or under-doses in radiation therapy.

    One of the main effects of the Chernobyl reactor accident is an increase in childhood papillary thyroid carcinomas (PTC) in the regions that were contaminated with radio-iodine from the fallout. Despite a considerable research effort, molecular profiles have yet to be identified that reliably distinguish between age matched patients with radiation associated and sporadic PTCs. Expression of micro RNAs (miRNA) have recently been studied extensively in many different cancer types. MiRNAs have the potential to provide insights into the network of molecular pathways that are involved in the development of tumorigenesis as they are involved in the regulation of networks of mRNAs. In addition, miRNAs can be studied in formalin-fixed paraffin embedded material, making them ideal for clinical studies. This study was designed specifically to identify differentially expressed miRNAs in patients with childhood PTC that were exposed (n=11) and non-exposed (n=9) to irradiation. The results suggest that in radiation-associated childhood PTC DNA repair processes which are reflected by genes that encode DNA-binding proteins are de-regulated. DNA mutation and double-strand breaks are induced by ionising radiation and subsequent mis-repair and inactivation of tumour suppressor genes and the activation of oncogenes leads to growth and proliferation of the tumour cell. These findings suggest that in addition to the MAP kinase pathway which is known to be a key pathway in PTC, additional pathways such as the Fc epsilon RI signalling, the VEGF pathway and p53 signalling pathway seem to be involved in radiation-associated tumorigenesis of PTC

    The International Consortium for Health Outcomes Measurement recently included the 10-item PROMIS GH (Patient-Reported Outcomes Measurement Information System Global Health) scale as part of their recommended Standard Set of Stroke Outcome Measures. Before collection of PROMIS GH is broadly implemented, it is necessary to assess its performance in the stroke population. The objective of this study was to evaluate the psychometric properties of PROMIS GH in patients with ischemic stroke and intracerebral hemorrhage. PROMIS GH and 6 PROMIS domain scales measuring same/similar constructs were electronically collected on 1102 patients with ischemic and hemorrhagic strokes at various stages of recovery from their stroke who were seen in a cerebrovascular clinic from October 12, 2015, through June 2, 2017. Confirmatory factor analysis was performed to evaluate the adequacy of 2-factor structure of component scores. Test-retest reliability and convergent validity of PROMIS GH items and component scores were assessed. Discriminant validity and responsiveness were compared between PROMIS GH and PROMIS domain scales measuring the same or related constructs. Analyses were repeated stratified by stroke subtype and modified Rankin Scale score validity was good with significant correlations between all PROMIS GH items and PROMIS domain scales ( P 0.5) was demonstrated for 8 of the 10 PROMIS GH items. Reliability and validity remained consistent across stroke subtype and disability level (modified Rankin Scale, <2 versus ≥2). PROMIS GH exhibits acceptable performance in patients with stroke. Our findings support International Consortium for Health Outcomes Measurement recommendation to use PROMIS GH as part of the standard set of outcome measures in stroke. © 2017 American Heart Association, Inc.

    As frontline nurses, we know firsthand the many challenges of renal disease faced by our patients and the impact on their lives and their families. How can we help them cope with their illness? How can we improve their quality of life? How can we prevent the complications inherent to the disease? How do we know we are doing a good job? Where do we start? The purpose of this presentation is to showcase the global management of the hemodialysis (HD) patient. It provides a collaborative and systematic approach to assessing, implementing, evaluating and coordinating the physiologic and the psychosocial aspects of their care. It is a model of case management followed by the Southern Alberta Renal Program (SARP) in meeting the many and complex needs of our hemodialysis patients. The quality indicators, to name a few, that relate to the physiologic aspects of their care are dialysis adequacy and fluid removal, improved blood pressure (BP) control, maintenance and improved vascular access function, anemia, bone and mineral disease management, nutritional, and diabetes management. The psychosocial aspects of care encompass goals of care, residential support, transportation, and mobility programs in the community. There may be positive implications resulting from our practice that we believe would be invaluable in terms of improved patient care, increased adherence to therapeutic regimens, improved mortality and morbidity and overall enhanced quality of life. Moreover, better communication would possibly be fostered and wise and prompt use of resources may be a result. To date, we have not done studies to prove or disprove these outcomes.

  10. Economic support to patients in HIV and TB grants in rounds 7 and 10 from the global fund to fight AIDS, tuberculosis and malaria.

    Directory of Open Access Journals (Sweden)

    Linda M Richter

    Full Text Available People with TB and/or HIV frequently experience severe economic barriers to health care, including out-of-pocket expenses related to diagnosis and treatment, as well as indirect costs due to loss of income. These barriers can both aggravate economic hardship and prevent or delay diagnosis, treatment and successful outcome, leading to increased transmission, morbidity and mortality. WHO, UNAIDS and the ILO argue that economic support of various kinds is essential to enable vulnerable people to protect themselves from infection, avoid delayed diagnosis and treatment, overcome barriers to adherence, and avert destitution. This paper analyses successful country proposals to the Global Fund to Fight AIDS, Tuberculosis and Malaria that include economic support in Rounds 7 and 10; 36 and 20 HIV and TB grants in Round 7 and 32 and 26, respectively, in Round 10. Of these, up to 84 percent included direct or indirect economic support for beneficiaries, although the amount constituted a very small proportion of the total grant. In TB grants, the objectives of economic support were generally clearly stated, and focused on mechanisms to improve treatment uptake and adherence, and the case was most clearly made for MDR-TB patients. In HIV grants, the objectives were much broader in scope, including mitigation of adverse economic and social effects of HIV and its treatment on both patients and families. The analysis shows that economic support is on the radar for countries developing Global Fund proposals, and a wide range of economic support activities are in place. In order to move forward in this area, the wealth of country experience that exists needs to be collated, assessed and disseminated. In addition to trials, operational research and programme evaluations, more precise guidance to countries is needed to inform evidence-based decision about activities that are cost-effective, affordable and feasible.

    The purpose of this paper is to review the service quality dimensions established in various studies conducted across the world specifically applied to health care. Studies conducted on quality of care selected from literature databases - Ebsco, Emerald Insight, ABI/Inform - was subjected to a comprehensive in-depth content analysis. Service quality has been extensively studied with considerable efforts taken to develop survey instruments for measuring purposes. The number of dimensional structure varies across the studies. Self-administered questionnaire dominates in terms of mode of administration adopted in the studies, with respondents ranging from 18 to 85 years. Target sample size ranged from 84-2,000 respondents in self-administered questionnaires and for mail administration ranged from 300-2,600 respondents. Studies vary in terms of the scores used ranging from four to ten-point scale. A total of 27 of the studies have used EFA, 11 studies have used structural equation modelling and eight studies used gap scores. Cronbach's alpha is the most commonly used measure of scale reliability. There is variation in terms of measuring the content, criteria and construct validation among the studies. The literature offers dimensions used in assessing patient perceived service quality. The review reveals diversity and a plethora of dimensions and methodology to develop the construct discussed. The reported study describes and contrasts a large number of service-quality measurement constructs and highlights the usage of dimensions. The findings are valuable to academics in terms of dimensions and methodology used, approach for analysis; whereas findings are of value to practitioners in terms of the dimensions found in the research and to identify the gap in their setting.

    Lysyl oxidase is overexpressed in the myocardium of patients with hypertensive cardiomyopathy. We aimed to explore whether patients with hypertensive-metabolic heart failure with preserved ejection fraction (HM-HFpEF) also have increased concentrations of circulating prolysyl oxidase (cpLOX) and its possible consequences. We quantified cpLOX concentrations in 85 nonischemic patients with stage C, HM-HFpEF, and compared them with those of 51 healthy controls. We also assessed the correlations of cpLOX with myocardial stiffness parameters, collagen turnover products and fibrogenic cytokines, as well as the predictive value of plasma proenzyme levels at 1-year of follow-up. We detected raised cpLOX values and found that they correlated with calculated E/E' ratios and stiffness constants. The subgroup of patients with type I diastolic dysfunction showed a single negative correlation between cpLOX and B-type natriuretic peptide whereas patients with a restrictive diastolic pattern showed a strong correlation between cpLOX and galectin-3. Kaplan-Meier analysis revealed that cpLOX > 52.20 ng/mL slightly increased the risk of a fatal outcome (log-rank = 4.45; P = .034). When Cox regression was used, cpLOX was found to be a significant independent predictor of cardiovascular death or hospitalization due to the decompensation of HM-HFpEF (HR, 1.360; 95%CI, 1.126-1.638; P = .046). Patients with symptomatic HM-HFpEF show high cpLOX serum levels associated with restrictive diastolic filling indices. These levels represent a moderate risk factor for poor clinical outcome. Throughout the natural history of HM-HFpEF, we observed that cpLOX concentrations were initially negatively correlated with B-type natriuretic peptide but positively correlated with galectin-3 as advanced diastolic dysfunction developed.

    Although Internal Medicine (IM) has played for many years a crucial role in the medical education and in the diagnostic framing of the most common diseases, starting from the beginning of the 70's the knowledge explosion, the recognition of the multidisciplinary nature of IM and the consequent impossibility for the Internist to master an ever growing array of notions have resulted in the development of specialized disciplines restricted to pathologies of single organs or apparatus. The parcelling out of medical knowledge has thus induced the onset of a number of specializations stemmed from IM and, as a direct consequence, an identity crisis of the same IM. Social transformations and variations in the epidemiology of several diseases have contributed to such crisis, including aging, frailty and disability, polypathology and chronicity. In the last few years, however, IM has regained a central role in medicine, in that the Internist is an expert of "medicine of complexity" and the only specialist able to envisage an holistic approach to the patient. The development of biotechnologies, characterized on one side by nanotechnologies and on the other by the instruments of diagnostic imaging, has provided an important contribution to make clinical medicine more and more precise and reliable. The genomic analysis of novel pharmacological targets has opened new therapeutic horizons, especially in the oncology field. A striking aspect of modern medicine, again based on unreasonable expectations of improvement and recovery, is the progressive increment of malpractice claims leading to an indemnity payment. Defensive medicine has been the answer to face this growing problem: physicians are in fact induced to prescribe a much higher number of often unnecessary examinations and laboratory tests, that result in a wasting rise of health costs. In view of the rapidly changing reality, it seems fair to ask the question as to whether in our country the medical education is abreast

    This study was carried out in order to investigate the possible detrimental effects on bone of levothyroxine (l-T{sub 4}) suppressive therapy in female patients who had undergone surgery for differentiated thyroid cancer (DTC). Twenty female (14 premenopausal and 6 postmenopausal) patients receiving l-T{sub 4} suppressive therapy for DTC were studied. The sample was selected in such a way as to avoid factors influencing bone metabolism other than l-T{sub 4}. All patients were monitored by sensitive thyroid-stimulating hormone, free triiodothyronine and free thyroxine assays throughout the follow-up. Nineteen healthy (12 premenopausal and 7 postmenopausal) matched women served as controls. In all subjects bone turnover was evaluated by the measurement of global skeletal uptake of technetium-99m methylene diphosphonate (GSU); bone mineral density (BMD) was measured by quantitative computed tomography at the lumbar spine (LS) and by dual-energy X-ray absorptiometry both at the LS and at three femoral sites: the femoral neck, Ward`s triangle and the greater trochanter. No significant difference was found in either GSU or BMD between patients (treated for an average period of 68 months) and controls in the whole sample or in any subgroup. Furthermore, no correlations were found between either GSU or BMD and the duration of therapy, daily doses of l-T{sub 4} or results of thyroid function tests. Our data show that carefully monitored l-T{sub 4} therapy does not influence skeletal turnover (directly reflected by GSU) or the bone density of the spine and femur. (orig.)

    Full Text Available Abstract Background Generalized arterial alterations, such as endothelial dysfunction, medial matrix accumulations, and calcifications are associated with type 2 diabetes (T2D. These changes may render the vessel wall more susceptible to injury; however, the molecular characteristics of such diffuse pre-atherosclerotic changes in diabetes are only superficially known. Methods To identify the molecular alterations of the generalized arterial disease in T2D, DNA microarrays were applied to examine gene expression changes in normal-appearing, non-atherosclerotic arterial tissue from 10 diabetic and 11 age-matched non-diabetic men scheduled for a coronary by-pass operation. Gene expression changes were integrated with GO-Elite, GSEA, and Cytoscape to identify significant biological pathways and networks. Results Global pathway analysis revealed differential expression of gene-sets representing matrix metabolism, triglyceride synthesis, inflammation, insulin signaling, and apoptosis. The network analysis showed a significant cluster of dysregulated genes coding for both intra- and extra-cellular proteins associated with vascular cell functions together with genes related to insulin signaling and matrix remodeling. Conclusions Our results identify pathways and networks involved in the diffuse vasculopathy present in non-atherosclerotic arterial tissue in patients with T2D and confirmed previously observed mRNA-alterations. These abnormalities may play a role for the arterial response to injury and putatively for the accelerated atherogenesis among patients with diabetes.

    Revascularization aims at improving walking ability in patients with arterial claudication. The highest measured distance between 2 stops (highest-MDCW), the average walking speed (average-WSCW), and the average stop duration (average-DSCW) can be measured by global positioning system, but their evolution after revascularization is unknown.We included 251 peripheral artery diseased patients with self-reported limiting claudication. The patients performed a 1-hour stroll, recorded by a global positioning system receiver. Patients (n = 172) with confirmed limitation (highest-MDCW the follow-up period were compared with reference patients (ie, with unchanged lifestyle medical or surgical status). Other patients (lost to follow-up or treatment change) were excluded (n = 89).We studied 44 revascularized and 39 reference patients. Changes in highest-MDCW (+442 vs. +13 m) and average-WSCW (+0.3 vs. -0.2 km h) were greater in revascularized than in reference patients (both P the groups. Among the revascularized patients, 13 (29.5%) had a change in average-WSCW, but not in highest-MDCW, greater than the mean + 1 standard deviation of the change observed for reference patients.Revascularization may improve highest-MDCW and/or average-WSCW. This first report of changes in community walking ability in revascularized patients suggests that, beyond measuring walking distances, average-WSCW measurement is essential to monitor these changes. Applicability to other surgical populations remains to be evaluated. http://www.clinicaltrials.gov/ct2/show/NCT01141361.

    Health services are now advertised in a global marketplace. Hip and knee replacements, ophthalmologic procedures, cosmetic surgery, cardiac care, organ transplants, and stem cell injections are all available for purchase in the global health services marketplace. "Medical tourism" companies market "sun and surgery" packages and arrange care at international hospitals in Costa Rica, India, Mexico, Singapore, Thailand, and other destination nations. Just as automobile manufacturing and textile production moved outside the United States, American patients are "offshoring" themselves to facilities that use low labor costs to gain competitive advantage in the marketplace. Proponents of medical tourism argue that a global market in health services will promote consumer choice, foster competition among hospitals, and enable customers to purchase high-quality care at medical facilities around the world. Skeptics raise concerns about quality of care and patient safety, information disclosure to patients, legal redress when patients are harmed while receiving care at international hospitals, and harms to public health care systems in destination nations. The emergence of a global market in health services will have profound consequences for health insurance, delivery of health services, patient-physician relationships, publicly funded health care, and the spread of medical consumerism.

    Undernourished patients discharged from the hospital require follow-up; however, attendance at return visits is low. Teleconsultations may allow remote follow-up of undernourished patients; however, no valid method to remotely perform physical examination, a critical component of assessing nutritional status, exists. This study aims to compare agreement between photographs taken by trained dietitians and in-person physical examinations conducted by trained dietitians to rate the overall physical examination section of the scored Patient Generated Subjective Global Assessment (PG-SGA). Nested cross-sectional study. Adults aged ≥60 years, admitted to the general medicine unit at Flinders Medical Centre between March 2015 and March 2016, were eligible. All components of the PG-SGA and photographs of muscle and fat sites were collected from 192 participants either in the hospital or at their place of residence after discharge. Validity of photograph-based physical examination was determined by collecting photographic and PG-SGA data from each participant at one encounter by trained dietitians. A dietitian blinded to data collection later assessed de-identified photographs on a computer. Percentage agreement, weighted kappa agreement, sensitivity, and specificity between the photographs and in-person physical examinations were calculated. All data collected were included in the analysis. Overall, the photograph-based physical examination rating achieved a percentage agreement of 75.8% against the in-person assessment, with a weighted kappa agreement of 0.526 (95% CI: 0.416, 0.637; Pexamination by trained dietitians achieved a nearly acceptable percentage agreement, moderate weighted kappa, and fair sensitivity-specificity pair. Methodological refinement before field testing with other personnel may improve the agreement and accuracy of photograph-based physical examination.

    The purpose of the present study is to evaluate diffusional anisotropy of white matter in patients with multiple lacunar infarcts using diffusion-weighted echo-planar imaging (DW-EPI), and to examine the relationship between diffusional anisotropy and global cognitive ability as assessed by the mini-mental status examination (MMSE). In particular, we focused on the parameter changes for the corpus callosum as a marker for disconnection of the associative cortices. Twenty-nine patients divided into 2 cognitive level groups (low MMSE, n=16; high MMSE, n=13) and 8 normal controls were examined with a GE 1.5 T Horizon system. Three series of DW-EPI images were obtained using the following epidw g ·psd TM sequence: TR/TE=6500/120 ms, single shot, 6.5 mm slice thickness and 1.5 mm gap transaxial sections of the whole brain, with b-factors of 0 and 710 along each x- and y-axial direction. The parametric maps for apparent diffusion coefficient (ADC) in each direction, ADC(x) and ADC(y), and their rate map (ADC rate=ADC(x)/ADC(y)) were created on a pixel-by-pixel basis. ROI data were extracted from images of the corpus callosum and bilateral optic radiata. As a result, the ADC(x) was markedly larger for corpus callosum than that for optic radiata, whereas the ADC(y) showed an inverse trend, attributable to regional differences of diffusional anisotropy. In corpus callosum, however, the ADC(y) values were observed to increase with the level of disease severity, resulting in a decrease of the ADC rate. Notably, there was a significant difference between the three groups for callosal genu, with a slight positive correlation between the ADC rate and the MMSE scores. Our study suggests that a relationship exists between the reduction of diffusional anisotropy in callosal genu and the global cognitive impairment seen in patients with multiple lacunar infarcts.

    Background Amidst the rise of e-commerce, there has been a proliferation of illicit online pharmacies that threaten global patient safety by selling drugs without a prescription directly to the consumer. Despite this clear threat, little is known about the key risk characteristics, central challenges and current legal, regulatory and law enforcement responses. Sources of data A review was conducted of the English literature with search terms ‘online pharmacies’, ‘Internet pharmacies’, ‘cyber pharmacies’, ‘rogue pharmacies’, and ‘e-pharmacies’ using PubMed, JSTOR, and Google Scholar from 1999–2005. Areas of agreement Illicit online pharmacies are a rapidly growing public health threat and are characterized by a number of complex and interrelated risk factors. Areas of controversy Solutions are varied and are of questionable utility in the face of evolving technology that enables this form of transnational cybercrime. Growing points Legal, regulatory and technology solutions must address the entire illicit online pharmacy ecosystem in order to be effective. Areas timely for developing research There is a critical need to build international consensus, conduct additional research and develop technology to combat illicit online pharmacies. PMID:27151957

    The American Museum of Natural History's Hayden Planetarium was rebuilt in year 2000 as an immersive theater for scientific data visualization to show the universe in context to our planet. Specific astrophysical movie productions provide the main daily programming, but interactive control software, developed at AMNH allows immersive presentation within a data aggregation of astronomical catalogs called the Digital Universe 3D Atlas. Since 2006, WMS globe browsing capabilities have been built into a software development collaboration with Sweden's Linkoping University (LiU). The resulting Uniview software, now a product of the company SCISS, is operated by about fifty planetariums around that world with ability to network amongst the sites for global presentations. Public presentation of NASA GIBS has allowed authoritative narratives to be presented within the range of data available in context to other sources such as Science on a Sphere, NASA Earth Observatory and Google Earth KML resources. Specifically, the NOAA supported World Views Network conducted a series of presentations across the US that focused on local ecological issues that could then be expanded in the course of presentation to national and global scales of examination. NASA support of for GIBS resources in an easy access multi scale streaming format like WMS has tremendously enabled particularly facile presentations of global monitoring like never before. Global networking of theaters for distributed presentations broadens out the potential for impact of this medium. Archiving and refinement of these presentations has already begun to inform new types of documentary productions that examine pertinent, global interdependency topics.

  8. Investigations into the myocardial metabolism of 123-I-ω-HDA in patients showing the clinical signs and symptoms of mitral valve prolapse and previously proven to have no coronary heart disease

    Voth, E.

    1987-01-01

    In 53 patients showing the clinical signs and symptoms of mitral valve prolapse (MVP) where coronary heart disease (CHD) had previously been excluded by angiography the myocardial metabolism of fatty acids was examined at rest using metabolic myocardial scintigraphy (MMS) and 123-I-ω-HDA as tracer substance. The results were correlated with those obtained by other methods of investigation (findings at rest and during exercise from ECG recordings, tests using a flow-guided catheter and radionuclide ventriculography, further from echocardiography as well as myocardial Tl redistribution scintiscanning during exercise). For purposes of reference, MMS was additionally carried out in twelve normal individuals subjected to coronary angiography to exclude both MVP and CHD. The results of this study would appear to suggest that the pathological findings revealed by myocardial Tl scintigraphy in patients showing symptoms of MVP cannot invariably be classified as 'false' but are at least to some extent attributable to impaired myocardial perfusion, vitality or metabolism.

    This study aimed to identify factors related to the illness and to oncological treatment as determinants of the nutritional status of patients with gynecological tumors. This is a retrospective study; the group was composed of 146 women histopathologically shown to have gynecological tumors, at different stages of treatment, and hospitalized at the foremost centers for the prevention and treatment of cancer in Rio de Janeiro. To obtain a nutritional diagnosis, we used the Patient-Generated Subjective Global Assessment (PG-SGA). We did multiple comparisons of the numeric variables between the three PG-SGA nutritional status-classification groups by performing Kruskal-Wallis analysis of variance. We used the Mann-Whitney test to compare numerical variables between two groups. We analyzed the associations between categorical variables by using either the chi-squared (χ (2)) test or Fisher's exact test. Of the women, 62.4 % were found to be at nutritional risk or to have some level of malnourishment, being more associated with the reason for hospital admission and stage disease that properly to the tumor site. The median PG-SGA score was points, with 62.3 % of the group returning 9 or more points. Women diagnosed with endometrial cancer were found to be predominantly well nourished, and those with tumors in the ovary were more frequently diagnosed as being severely malnourished. Our findings support early nutritional intervention in the population identified as being at greater nutritional risk, aiming to minimize the loss of muscle mass and body weight, as well as to improve symptoms management, thus helping to achieve better clinical results.

    Psycho-education is now considered as part of the integrated treatment for bipolar disorder. This study aimed to determine the efficacy of group psycho-education on medication adherence and global functioning of patients with bipolar disorder type I. 45 patients with bipolar disorder type I were allocated one of the three groups of psycho-education plus pharmacotherapy, pharmacotherapy and placebo plus pharmacotherapy. A psycho-educational program was conducted for the psycho-educational group during 9 weekly sessions. Medication adherence and global functioning of all the three groups were evaluated before the intervention, three months and six months after the intervention using Medication Adherence Rating Scale (MARS) and Global Assessment of Functioning (GAF). ANOVA was performed to examine the data. In the first and second assessments, the mean score of medication adherence and gobal functioning for patients in the psycho-educational group was significantly higher than that in the control and placebo groups (P=0.001). Medication adherence score of the psycho-educational group was increased from 6.27(0.88) to 7.92(1.38). while the mean score of the psycho-educational group increased from 56.6 (3.58) to 64.17 (2.12):, the global functioning reduced from 56.27(3.17) to 54.17(5.08) in the control group and from 56.67 (3.58) to 56 (4.36) in the placebo group. Psycho-educational program plus pharmacotherapy was effective in improvement medication adherence and global functioning of bipolar patients.

    Patient-reported outcomes (PROs) from social media use in chronic disease management continue to emerge. While many published articles suggest the potential for social media is positive, there is a lack of robust examination into mediating mechanisms that might help explain social media's therapeutic value. This study presents findings from a global online survey of people with chronic pain (PWCP) to better understand how they use social media as part of self-management. Our aim is to improve understanding of the various health outcomes reported by PWCP by paying close attention to therapeutic affordances of social media. We wish to examine if demographics of participants underpin health outcomes and whether the concept of therapeutic affordances explains links between social media use and PROs. The goal is for this to help tailor future recommendations for use of social media to meet individuals' health needs and improve clinical practice of social media use. A total of 231 PWCP took part in a global online survey investigating PROs from social media use. Recruited through various chronic disease entities and social networks, participants provided information on demographics, health/pain status, social media use, therapeutic affordances, and PROs from use. Quantitative analysis was performed on the data using descriptive statistics, cross-tabulation, and cluster analysis. The total dataset represented 218 completed surveys. The majority of participants were university educated (67.0%, 146/218) and female (83.9%, 183/218). More than half (58.7%, 128/218) were married/partnered and not working for pay (75.9%, 88/116 of these due to ill health). Fibromyalgia (46.6%, 55/118) and arthritis (27.1%, 32/118) were the most commonly reported conditions causing pain. Participants showed a clear affinity for social network site use (90.0%, 189/210), followed by discussion forums and blogs. PROs were consistent, suggesting that social media positively impact psychological

    Full Text Available In the present study, an enzyme-linked immunosorbent assay (ELISA standardized with vesicular fluid of Taenia solium cysticerci was used to screen for IgG (total and subclasses and IgE antibodies in cerebrospinal fluid (CSF samples from patients with neurocysticercosis showing intrathecal production of specific IgG antibodies and patients with other neurological disorders. The following results were obtained: IgG-ELISA: 100% sensitivity (median of the ELISA absorbances (MEA=1.17 and 100% specificity; IgG1-ELISA: 72.7% sensitivity (MEA=0.49 and 100% specificity; IgG2-ELISA: 81.8% sensitivity (MEA=0.46 and 100% specificity; IgG3-ELISA: 63.6% sensitivity (MEA=0.12 and 100% specificity; IgG4-ELISA: 90.9% sensitivity (MEA=0.85 and 100% specificity; IgE-ELISA 93.8% sensitivity (MEA=0.60 and 100% specificity. There were no significant differences between the sensitivities and specificities in the detection of IgG-ELISA and IgE-ELISA, although in CSF samples from patients with neurocysticercosis the MEA of the IgG-ELISA was significantly higher than that of the IgE-ELISA. The sensitivity and MEA values of the IgG4-ELISA were higher than the corresponding values for the other IgG subclasses. Future studies should address the contribution of IgG4 and IgE antibodies to the physiopathology of neurocysticercosis.

    More accurate diagnostic procedures for prostate cancer are needed to avoid unnecessary biopsy due to the low specificity of prostate-specific antigen (PSA). Recent studies showed that the percentage of serum isoform [-2]proPSA (p2PSA) to free PSA (%p2PSA), the Prostate Health Index (PHI) and magnetic resonance imaging (MRI) were more accurate than PSA. The aim of this study was to test the accuracy of %p2PSA, PHI and MRI in discriminating patients with and without prostate cancer. The subjects were 50 consecutive men with a PSA level of 2.0-10.0 ng/ml, who underwent prostate biopsy from October 2012 to July 2014. These patients underwent multiparametric MRI before biopsy, and their serum samples were measured for PSA, free PSA and p2PSA. The sensitivity, specificity and accuracy of PHI, %p2PSA and MRI were compared with PSA in the diagnosis of biopsy-confirmed prostate cancer. In a univariate analysis, %p2PSA [area under the curve (AUC): 0.811] and PHI (AUC 0.795) were more accurate than MRI (AUC: 0.583) and PSA (AUC: 0.554) for prostate cancer detection. At 60% sensitivity, the specificity of PHI (76.5%) was higher than that of MRI (52.9%). For significant cancer detection, %p2PSA (AUC: 0.745), PHI (AUC: 0.791) and MRI (AUC: 0.739) were marginally more accurate than PSA (AUC: 0.696). At 85% sensitivity, the specificity of MRI (62.1%) was higher than that of PHI (34.5%). PHI and %p2PSA can be used for screening the general population and MRI can be used for detection of significant cancer in patients suspected, from screening tests, of having prostate cancer.

    Highlights: Black-Right-Pointing-Pointer Circulating DNAs (CDs) can be used to detect genetic/epigenetic abnormalities in MDS. Black-Right-Pointing-Pointer Epigenetic changes can be detected more sensitively when using plasma DNA than PBMNC. Black-Right-Pointing-Pointer Mutation ratio in CDs may reflect the ratio in stem cell population in bone marrow. Black-Right-Pointing-Pointer Using CDs can be a safer alternate strategy compared to bone marrow aspiration. -- Abstract: Myelodysplastic syndrome (MDS) is a hematopoietic stem cell disorder. Several genetic/epigenetic abnormalities are deeply associated with the pathogenesis of MDS. Although bone marrow (BM) aspiration is a common strategy to obtain MDS cells for evaluating their genetic/epigenetic abnormalities, BM aspiration is difficult to perform repeatedly to obtain serial samples because of pain and safety concerns. Here, we report that circulating cell-free DNAs from plasma and serum of patients with MDS can be used to detect genetic/epigenetic abnormalities. The plasma DNA concentration was found to be relatively high in patients with higher blast cell counts in BM, and accumulation of DNA fragments from mono-/di-nucleosomes was confirmed. Using serial peripheral blood (PB) samples from patients treated with hypomethylating agents, global methylation analysis using bisulfite pyrosequencing was performed at the specific CpG sites of the LINE-1 promoter. The results confirmed a decrease of the methylation percentage after treatment with azacitidine (days 3-9) using DNAs from plasma, serum, and PB mono-nuclear cells (PBMNC). Plasma DNA tends to show more rapid change at days 3 and 6 compared with serum DNA and PBMNC. Furthermore, the TET2 gene mutation in DNAs from plasma, serum, and BM cells was quantitated by pyrosequencing analysis. The existence ratio of mutated genes in plasma and serum DNA showed almost equivalent level with that in the CD34+/38- stem cell population in BM. These data suggest that genetic

    European Society for Clinical Nutrition and Metabolism (ESPEN) commenced in 2004 a global health project named "NutritionDay" aiming to promote awareness of proper nutritional status of hospitalized patients and to draw attention to the need for early detection of malnutrition among patients. Under the Polish law--pursunat to the regulation of the Minister of Health dated September 15, 2011 (amendment as of 27.12.2013)--a nutritional status of each patient should be assessed at the time of a hospital admission. of this study was to analyze the fulfilment of the mandatory questionnaire assessment of nutritional status at selected wards of one of Warsaw's clinical hospitals. The study included an analysis of medical records of patients hospitalized within 6 months (n = 26375). The correct fulfilment of screening questionnaire assessing nutritional status (NRS 2002 survey) and the information about patients' body weight as well as the results assessment of nutritional status were subject to the analysis. NRS 2002 questionnaire was present in only 67,14% medical records of patients, however 49.24% of them were unfilled. The obtained results confirming low degree of NRS 2002 questionnaires' fulfilment in one of the Warsaw clinical hospitals draws attention to the need for education of hospital personnel in the field of significance of screening of nutritional assessment and its regulations. The "NutritionDay" project is an interesting form to attract attention of the aforementioned problem and its global extent additionally encourage medical units to participate in the project.

    Full Text Available Abstract Background The aim of this study was to prospectively examine echocardiographic parameters that correlate and predict functional capacity assessed by 6 min walk test (6-MWT in patients with heart failure (HF, irrespective of ejection fraction (EF. Methods In 147 HF patients (mean age 61 ± 11 years, 50.3% male, a 6-MWT and an echo-Doppler study were performed in the same day. Global LV dyssynchrony was indirectly assessed by total isovolumic time - t-IVT [in s/min; calculated as: 60 – (total ejection time + total filling time], and Tei index (t-IVT/ejection time. Patients were divided into two groups based on the 6-MWT distance (Group I: ≤300 m and Group II: >300 m, and also in two groups according to EF (Group A: LVEF ≥ 45% and Group B: LVEF  Results In the cohort of patients as a whole, the 6-MWT correlated with t-IVT (r = −0.49, p  Conclusion In patients with HF, the limited exercise capacity, assessed by 6-MWT, is related mostly to severity of global LV dyssynchrony, more than EF or raised filling pressures. The lack of exercise predictors in HFpEF reflects its multifactorial pathophysiology.

    Global Registry of Acute Coronary Events (GRACE) risk score and red blood cell distribution width (RDW) content can both independently predict major adverse cardiac events (MACEs) in patients with acute coronary syndrome (ACS). We investigated the combined predictive value of RDW and GRACE risk score for cardiovascular events in patients with ACS undergoing percutaneous coronary intervention (PCI) for the first time. We enrolled 480 ACS patients. During a median follow-up time of 37.2 months, 70 (14.58%) patients experienced MACEs. Patients were divided into tertiles according to the baseline RDW content (11.30-12.90, 13.00-13.50, 13.60-16.40). GRACE score was positively correlated with RDW content. Multivariate Cox analysis showed that both GRACE score and RDW content were independent predictors of MACEs (hazard ratio 1.039; 95% confidence interval [CI] 1.024-1.055; p risk of MACEs increased with increasing RDW content (p value of combining RDW content and GRACE risk score was significantly improved, also shown by the net reclassification improvement (NRI = 0.352, p value of RDW and GRACE risk score yielded a more accurate predictive value for long-term cardiovascular events in ACS patients who underwent PCI as compared to each measure alone.

    We review the use of behavior from television game shows to infer risk attitudes. These shows provide evidence when contestants are making decisions over very large stakes, and in a replicated, structured way. Inferences are generally confounded by the subjective assessment of skill in some games......, and the dynamic nature of the task in most games. We consider the game shows Card Sharks, Jeopardy!, Lingo, and finally Deal Or No Deal. We provide a detailed case study of the analyses of Deal Or No Deal, since it is suitable for inference about risk attitudes and has attracted considerable attention....

    2016-01-01

    Healthcare systems globally continue to face challenges surrounding patient identification. Consequences of misidentification include incomplete and inaccurate electronic patient health records potentially jeopardizing patients' safety, a significant amount of cases of medical fraud because of inadequate identification mechanisms, and difficulties affiliated with the value of remote health self-management application data being aggregated accurately into the user's Electronic Health Record (EHR). We introduce a new technique of user identification in healthcare capable of establishing a global identifier. Our research has developed algorithms capable of establishing a Unique Health Identifier (UHID) based on the user's fingerprint biometric, with the utilization of facial-recognition as a secondary validation step before health records can be accessed. Biometric captures are completed using standard smartphones and Web cameras in a touchless method. We present a series of experiments to demonstrate the formation of an accurate, consistent, and scalable UHID. We hope our solution will aid in the reduction of complexities associated with user misidentification in healthcare resulting in lowering costs, enhancing population health monitoring, and improving patient-safety.

    Full Text Available Abstract Background The objective of this analysis was to evaluate the psychometric properties of a brief scale developed to assess the degree of difficulties in children with Attention-Deficit/Hyperactivity Disorder (ADHD. The Global Impression of Perceived Difficulties (GIPD scale reflects overall impairment, psychosocial functioning and Quality of Life (QoL as rated by patient, parents and physician at various times of the day. Methods In two open-label studies, ADHD-patients aged 6–17 years were treated with atomoxetine (target-dose 0.5–1.2 mg/kg/day. ADHD-related difficulties were assessed up to week 24 using the GIPD. Data from both studies were combined to validate the scale. Results Overall, 421 patients received atomoxetine. GIPD scores improved over time. All three GIPD-versions (patient, parent, physician were internally consistent; all items showed at least moderate item-total correlation. The scale showed good test-retest reliability over a two-week period from all three perspectives. Good convergent and discriminant validity was shown. Conclusion GIPD is an internally consistent, reliable and valid measure to assess difficulties in children with ADHD at various times of the day and can be used as indicator for psychosocial impairment and QoL. The scale is sensitive to treatment-related change.

    Full Text Available

    O fenômeno dos reality shows - e a subseqüente relação entre imagem e verdade - assenta-se sobre uma série de paradoxos. Tais paradoxos podem ser compreendidos à luz do pensamento do filósofo alemão Friedrich Nietzsche, que, através dos usos de formulações paradoxais, concebia a realidade como um mundo de pura aparência e a verdade como um acréscimo ficcional, como um efeito. A ficção é então tomada, na filosofia de Nietzsche, não em seu aspecto falsificante e desrealizador - como sempre pleiteou nossa tradição metafísica -, mas como condição necessária para que certa espécie de invenção possa operar como verdade. Sendo assim, a própria expressão reality show, através de sua formulação paradoxal, engendra explicitamente um mundo de pura aparência, em que a verdade, a parte reality da proposição, é da ordem do suplemento, daquilo que se acrescenta ficcionalmente - como um adjetivo - a show. O ornamento, nesse caso, passa a ocupar o lugar central, apontando para o efeito produzido: o efeito-de-verdade. Seguindo, então, o pensamento nietzschiano e sua atualização na contemporaneidade, investigaremos de que forma os televisivos “shows de realidade” operam paradoxalmente, em consonância com nossas paradoxais práticas culturais.

    Patients' subjective impression of change is an important construct to measure following physiotherapy, but little evidence exists about the best type of measure to use. To compare the construct validity and utility of two forms of a global subjective outcome scale (GSOS) in patients with back pain: Likert and visual analogue scale (VAS) GSOS. Two samples of patients attending physiotherapy for back pain completed a questionnaire battery at discharge from physiotherapy including either a Likert or VAS GSOS. One hundred and eighty-seven {79 males, mean age 52.1 [standard deviation (SD) 15.5] years} patients completed the Likert GSOS and a separate sample of 144 patients [62 males, mean age 55.7 (SD 15.9) years] completed the VAS GSOS upon discharge from physiotherapy. The two versions of the GSOS were compared using pre- and post-treatment changes in scores using a VAS (pain), Roland-Morris Disability Questionnaire (18-item version) and catastrophising subscale of the Coping Strategies Questionnaire 24.

    To examine patient and physician beliefs regarding insulin therapy and the degree to which patients adhere to their insulin regimens. Internet survey of 1250 physicians (600 specialists, 650 primary care physicians) who treat patients with diabetes and telephone survey of 1530 insulin-treated patients (180 with Type 1 diabetes, 1350 with Type 2 diabetes) in China, France, Japan, Germany, Spain, Turkey, the UK or the USA. One third (33.2%) of patients reported insulin omission/non-adherence at least 1 day in the last month, with an average of 3.3 days. Three quarters (72.5%) of physicians report that their typical patient does not take their insulin as prescribed, with a mean of 4.3 days per month of basal insulin omission/non-adherence and 5.7 days per month of prandial insulin omission/non-adherence. Patients and providers indicated the same five most common reasons for insulin omission/non-adherence: too busy; travelling; skipped meals; stress/emotional problems; public embarrassment. Physicians reported low patient success at initiating insulin in a timely fashion and adjusting insulin doses. Most physicians report that many insulin-treated patients do not have adequate glucose control (87.6%) and that they would treat more aggressively if not for concern about hypoglycaemia (75.5%). Although a majority of patients (and physicians) regard insulin treatment as restrictive, more patients see insulin treatment as having positive than negative impacts on their lives. Glucose control is inadequate among insulin-treated patients, in part attributable to insulin omission/non-adherence and lack of dose adjustment. There is a need for insulin regimens that are less restrictive and burdensome with lower risk of hypoglycaemia. © 2012 The Authors. Diabetic Medicine © 2012 Diabetes UK.

    The objective of the study was to compare estimates of pediatric cumulative exposure and lifetime attributable risk (LAR) of radiation-induced cancer from dental radiology between cleft palate (CP) subjects and age- and gender-matched controls (non-CP), with and without orthodontic treatment. The radiation exposure frequency of CP subjects and non-CP controls with and without orthodontic treatment was compared for two-dimensional radiography (intra-oral, panoramic and cephalometric radiography), computed tomography (CT), and cone-beam CT (CBCT) using cumulative radiation dose as an estimate. From this dose estimate, the age- and gender-dependent risk for radiation-induced stochastic effects was calculated for each patient group. CP patients received more radiographic examinations than non-CP controls, with the exception of intra-oral radiographs. The cumulative dose to CP patients was considerably higher (1963 μSv at the age of 20 years) than non-CP patients with (597 μSv) and without (383 μSv) orthodontic treatment, primarily due to the higher frequency of CT scanning. Accordingly, CP patients had a three to five times higher LAR than non-CP patients. This study suggests a significantly higher lifetime radiation exposure to CP patients than non-CP controls from dental radiographic procedures. Diagnostic benefits from the use of CT and CBCT in children must be justified and appropriate dose optimization strategies implemented. The present study indicates the need for proper justification and optimization of pediatric exposures in dentistry, with a special focus on high-risk groups.

    To investigate the effectiveness of pulmonary rehabilitation (PR) in exercise capacity and quality of life in patients with chronic obstructive pulmonary disease (COPD) with and without global fat-free mass (FFM) depletion. Retrospective case-control. Outpatient clinic, university center. COPD patients (N=102) that completed PR were initially evaluated. PR including whole-body and weight training for 12 weeks, 3 times per week. St. George Respiratory Questionnaire (SGRQ), 6-minute walk distance (6MWD), and FFM evaluation applied before and after PR. Patients were stratified according to their FFM status measured by bioelectric impedance. They were considered depleted if the FFM index was ≤ 15 kg/m(2) in women and ≤ 16 kg/m(2) in men. From the initial sample, all depleted patients (n=31) composed the FFM depleted group. It was composed predominantly by women (68%) with a mean age ± SD of 64.4 ± 7.3 years and a forced expiratory volume in 1 second of 33.6%=-13.2% predicted. Paired for sex and age, 31 nondepleted patients were selected from the initial sample to compose the nondepleted group. Improvement in the 6MWD was similar in these 2 groups after PR. Both groups improved SGRQ scores, although the observed power was small and did not allow adequate comparison between depleted and nondepleted patients. There was no difference between groups in weight change, whereas FFM tended to be greater in depleted patients. This increase had no correlation with the 6MWD or the SGRQ. Benefits of PR to exercise capacity were similar comparing FFM depleted and nondepleted COPD patients. Although FFM change tended to be greater in depleted patients, this increase had no definite relation with clinical outcomes. Copyright © 2013 American Congress of Rehabilitation Medicine.

    Accurate assessment of myocardial viability permits selection of patients who would benefit from myocardial revascularization. Currently, rest-redistribution thallium-201 scintigraphy and low-dose dobutamine echocardiography are among the most used techniques for the identification of viable myocardium. Thirty-one consecutive patients (all men, mean age 60±8 years) with chronic coronary artery disease and reduced left ventricular ejection fraction (31%±7%) were studied. Rest 201 Tl single-photon emission tomography (SPET), low-dose dobutamine echocardiography and radionuclide angiography were performed before revascularization. Radionuclide angiography and echocardiography were repeated after revascularization. An a/dyskinetic segment was considered viable on 201 Tl SPET when tracer uptake was >65%, while improvement on low-dose dobutamine echocardiography was considered a marker of viability. Increase in global ejection fraction was considered significant at ≥5%. In identifying viable segments, rest 201 Tl SPET showed higher sensitivity than low-dose dobutamine echocardiography (72% vs 53%, P 201 Tl SPET in group 1 than in group 2 (2.6±1.9 vs 0.6±1.2, P 201 Tl SPET and post-revascularization changes in ejection fraction (r=0.52, P 201 Tl SPET had a higher sensitivity (82% vs 53%, P=0.07) and showed a trend towards higher accuracy and specificity (77% vs 58%, and 71% vs 64%, respectively) as compared with low-dose dobutamine echocardiography. In conclusion, these findings suggest that when severely reduced global function is present, rest 201 Tl SPET evaluation of viability is more accurate than low-dose dobutamine echocardiography for the identification of patients who will benefit most from revascularization.

    The objective of this study was to assess the current relationship between certain demographics and chemical factors, and the risk of cardiovascular complications, within a Puerto Rican population with diabetes mellitus. A total of 2075 patients with diabetes mellitus were retrospectively evaluated to determine the influence of certain demographics and chemical variables on the appearance of cardiovascular complications. A group of demographic and laboratory variables were analyzed. Our sample was obtained, based on convenience, from an endocrinologist's office in an area of about 250 000 people. All the patients met the American Diabetes Association (ADA) definitions for diabetes mellitus. The study covered a time period of 8 years. The patients signed an informed consent document at their first office visit. Data were obtained by the endocrinologist in charge. We considered the demographic variables of sex, age, time with diabetes, lipid profile, metabolic control (measured with glycated hemoglobin levels), and microalbumin renal excretion. Cardiovascular complications were more prevalent in patients with poor metabolic control, those with prolonged disease duration, men, and patients who were more than 50 years of age. We found no relationship between cardiovascular disease, systolic blood pressure over 130 mm Hg, body mass index and low-density lipoprotein cholesterol levels over 100 mg/dL. In Puerto Rican patients with diabetes mellitus, there is a statistically significant relationship between patient's gender, age, disease duration, glycemic control and increased kidney microalbumin excretion with cardiovascular complications.

    Purpose: To determine the importance of downstaging of locally advanced rectal cancer after neoadjuvant treatment. Methods and Materials: The study included all consecutive patients with locally advanced rectal cancer who underwent neoadjuvant treatment (chemotherapy and/or radiotherapy) in different Italian centers from June 1996 to December 2003. A novel score was used, calculated as the sum of numbers obtained by giving a negative or positive point, respectively, to each degree of increase or decrease in clinical to pathologic T and N status. Results: A total of 317 patients were eligible for analysis. Neoadjuvant treatments performed were as follows: radiotherapy alone in 75 of 317 patients (23.7%), radiotherapy plus chemotherapy in 242 of 317 patients (76.3%). Worse disease-free survival was observed in patients with a lower score (Score 1 = -3 to +3 vs. Score 2 = +4 to +7; p = 0.04). Conclusions: Our results suggest that a novel score, calculated from preoperative and pathologic tumor and lymph node status, could represent an important parameter to predict outcome in patients receiving neoadjuvant treatment for rectal cancer. The score could be useful to select patients for adjuvant chemotherapy after neoadjuvant treatment and surgery.

    An analysis of hormone measurements in sera from healthy volunteers and patients that was carried out on the basis of different criteria yielded the following results: 1) The testosterone levels determined in the patients sera were significantly lower than those of the healthy individuals and the daily rhythmic variations seen here did not attain statistical significance. 2) There were no statistically relevant differences in the serum concentrations of cortisol between healthy individuals and patients, nor was the amplitude of the daily variations observed to be changed in a consistent way. 3) In the patients, as compared to the healthy individuals, the prolactin level was considerably increased, as was the amplitude of the daily rhythmic variations. 4) The values determined for the human growth hormone (HCG) varied considerably between the individuals of either group. Since this held true for both the fluctuations with time and the height of the serum concentrations, a statistical analysis of the results appeared pointless. The results confirm that central and autonomous components have an important role in ectopic eczemae. (TRV) [de

    In 13 patients with transient global amnesia (TGA), we studied the clinical course and changes over time by means of imaging techniques such as SPECT. MRI, and proton MR spectroscopy ({sup 1}H-MRS). In the case of SPECT, a cerebral blood flow decrease at the time center of the temporal lobe persisted at least for more than one month. In many patients, no abnormal signs were found on MRI. Despite the presence of intracranial impairment of energy metabolism, no evidence of cerebral ischemia was obtained using {sup 1}H-MRS at the acute and subacute stages. There were thus discrepancies between the symptoms and the findings of SPECT as well as the findings of {sup 1}H-MRS. These data suggest that TGA may not necessarily be caused by cerebra1 ischemia.

    This study aims to analyze the published literatures on the effect of less radical fertility-preserving procedures, such as conization or simple trachelectomy, on oncological outcomes in IA1 cervical cancer patients with lymphovascular space invasion (LVSI) through a systematic-review. The EMBASE and MEDLINE databases and Cochrane Library were searched for published studies reporting the oncological outcomes of conization/simple trachelectomy in these patients, through April 2017. The endpoints were recurrence and mortality rates. Data were presented as per the Meta-analysis Of Observational Studies in Epidemiology checklist. Practice guidelines were generated via the Grading of Recommendation, Assessment, Development and Evaluation system. From 6,755 records, 94 full-texts articles were reviewed for eligibility, and five studies were included in this systematic review. All included studies were nonrandomized studies: two case-control studies comparing conization (n = 14) with hysterectomy (n = 24), and the other three were interrupted time series including conization (n = 20) and simple vaginal trachelectomy (n = 59). During the median follow-up duration of 43 months, no recurrence was reported in both conization and simple trachelectomy groups in IA1 patients with LVSI. From three studies reporting the fertility outcomes, the rates of pregnancy, live birth, preterm delivery, and second-trimester miscarriage were 73% (35/48), 64% (32/50), 10% (5/48), and 6% (3/48), respectively. Results suggest that simple trachelectomy or conization could be performed for IA1 cervical cancer patients with LVSI who want to preserve fertility, although these results are only based on a small number of nonrandomized studies (recommendation grade 2 = weak; evidence level D = very low). Further randomized trials with long-term study period are needed to address this issue.

    Motor neuron disease is a devastating neurodegenerative condition, with the majority of sporadic, non-familial cases being of unknown etiology. Several epidemiological studies have suggested that occupational exposure to chemicals may be associated with disease pathogenesis. We report the case of a patient developing progressive motor neuron disease, who was chronically exposed to pesticides and organic solvents. The patient presented with leg spasticity and developed gradually clinical signs suggestive of amyotrophic lateral sclerosis, which was supported by the neurophysiologic and radiological findings. Our report is an evidence based case of combined exposure to organochlorine (DDTs), organophosphate pesticides (OPs) and organic solvents as confirmed by laboratory analysis in samples of blood and hair confirming systematic exposure. The concentration of non-specific dialkylphosphates metabolites (DAPs) of OPs in hair (dimethyphopshate (DMP) 1289.4 pg/mg and diethylphosphate (DEP) 709.4 pg/mg) and of DDTs (opDDE 484.0 pg/mg, ppDDE 526.6 pg/mg, opDDD 448.4 pg/mg, ppDDD + opDDT 259.9 pg/mg and ppDDT 573.7 pg/mg) were considerably significant. Toluene and n-hexane were also detected in blood on admission at hospital and quantified (1.23 and 0.87 {mu}g/l, respectively), while 3 months after hospitalization blood testing was found negative for toluene and n-hexane and hair analysis was provided decrease levels of HCHs, DDTs and DAPs. -- Highlights: Black-Right-Pointing-Pointer Exposure to pesticides and organic solvents might be a risk factor for sporadic MND.

    There are over 1 million hospitalizations for heart failure (HF) annually in the United States alone, and a similar number has been reported in Europe. Recent clinical trials investigating novel therapies in patients with hospitalized HF (HHF) have been negative, and the post-discharge event rate remains unacceptably high. The lack of success with HHF trials stem from problems with understanding the study drug, matching the drug to the appropriate HF subgroup, and study execution. Related to the concept of study execution is the importance of including appropriate study sites in HHF trials. Often overlooked issues include consideration of the geographic region and the number of patients enrolled at each study center. Marked differences in baseline patient co-morbidities, serum biomarkers, treatment utilization and outcomes have been demonstrated across geographic regions. Furthermore, patients from sites with low recruitment may have worse outcomes compared to sites with higher enrollment patterns. Consequently, sites with poor trial enrollment may influence key patient end points and likely do not justify the costs of site training and maintenance. Accordingly, there is an unmet need to develop strategies to identify the right study sites that have acceptable patient quantity and quality. Potential approaches include, but are not limited to, establishing a pre-trial registry, developing site performance metrics, identifying a local regionally involved leader and bolstering recruitment incentives. This manuscript summarizes the roundtable discussion hosted by the Food and Drug Administration between members of academia, the National Institutes of Health, industry partners, contract research organizations and academic research organizations on the importance of selecting optimal sites for successful trials in HHF.

    Full Text Available Background: Remission is the target for management of rheumatoid arthritis (RA and intensification of immunosuppressive therapy is recommended for those that do not achieve this status. Patient global assessment (PGA is the single patient reported outcome considered in the American College of Rheumatology/European League Against Rheumatism remission criteria, but its use as target has been questioned. The primary aim of this study is to assess whether excluding PGA from the definition of disease remission changes the association of disease remission with long-term radiographic damage and physical function in patients with RA. Methods: Individual Patient Data Meta-analysis using data from randomized controlled trials of biological and targeted synthetic agents, identified through ClinicalTrials.gov and PubMed. Different remission states will be defined: (i 4v-remission [tender (TJC28 and swollen 28-joint counts (SJC28 both≤1, C-reactive protein (CRP≤1 (mg/dl, and PGA≤1 (0-10 scale], (ii 4v-near-remission (TJC28≤1, SJC28≤1, CRP≤1, and PGA>1, (iii non-remission (TJC28>1 or SJC28>1 or CRP>1, all mutually exclusive, and (iv 3v-remission (TJC28≤1, SJC28≤1, CRP≤1. Likelihood ratios will be used to descriptively compare whether meeting the 3v and 4v-remission criteria in a single visit (at 6 or 12 months predicts good outcome in the second year (1-2y. Differences in the predictive value of PGA in the definition of remission will be assessed by comparing the three mutually exclusive disease states using logistic regression analysis. Good outcome is defined primarily by radiographic damage (no deterioration in radiographic scores, whatever the instrument used in each trial, and secondarily by functional disability (Health Assessment Questionnaire consistently ≤0.5 and no deterioration, and their combination (“overall good outcome”. Additional analyses will consider longer periods over which to (concurrently define remission status

    Schizophrenia is a chronic disease that requires long-term management with antipsychotics. Antipsychotic drugs are given by tapering their dose, extending the dosing interval, and so on, as part of a treatment strategy to minimize the adverse effects while at the same time maintaining efficacy. We report the case of one patient with schizophrenia in whom the clinical symptoms were alleviated after treatment with 6 mg paliperidone. However, the patient developed extrapyramidal syndrome, for which 3 and 6 mg paliperidone were administered alternately every other day. Extrapyramidal syndrome was assessed using the Drug-Induced Extrapyramidal Symptoms Scale, Abnormal Involuntary Movement Scale, or Barnes Akathisia Scale. There was improvement in Drug-Induced Extrapyramidal Symptoms Scale score and Abnormal Involuntary Movement Scale score. However, there was almost no change in the Positive and Negative Syndrome Scale total score, positive score, negative score, or general score. The results indicate the possibility of lessened adverse effects as a result of an alternative regimen of treatment with paliperidone 3 and 6 mg every other day in the maintenance phase.

    The dic(9;20)(p11-13;q11) is a recurrent chromosomal abnormality in patients with acute lymphoblastic leukemia. Although it results in loss of material from 9p and 20q, the molecular targets on both chromosomes have not been fully elucidated. From an initial cohort of 58 with acute lymphoblastic leukemia patients with this translocation, breakpoint mapping with fluorescence in situ hybridization on 26 of them revealed breakpoint heterogeneity of both chromosomes. PAX5 has been proposed to be the target gene on 9p, while for 20q, FISH analysis implicated the involvement of the ASXL1 gene, either by a breakpoint within (n=4) or centromeric (deletion, n=12) of the gene. Molecular copy-number counting, long-distance inverse PCR and direct sequence analysis identified six dic(9;20) breakpoint sequences. In addition to the three previously reported: PAX5-ASXL1, PAX5-C20ORF112 and PAX5-KIF3B; we identified three new ones in this study: sequences 3' of PAX5 disrupting ASXL1, and ZCCHC7 disrupted by sequences 3' of FRG1B and LOC1499503. This study provides insight into the breakpoint complexity underlying dicentric chromosomal formation in acute lymphoblastic leukemia and highlights putative target gene loci.

    To evaluate construct validity, interpretability, reliability and responsiveness as well as determination of cut-off points for good and poor health within the original English version and the 18 translations of the disease-specific Assessment of Spondyloarthritis international Society Health Index (ASAS HI) in 23 countries worldwide in patients with spondyloarthritis (SpA). A representative sample of patients with SpA fulfilling the ASAS classification criteria for axial (axSpA) or peripheral SpA was used. The construct validity of the ASAS HI was tested using Spearman correlation with several standard health outcomes for axSpA. Test-retest reliability was assessed by intraclass correlation coefficients (ICCs) in patients with stable disease (interval 4-7 days). In patients who required an escalation of therapy because of high disease activity, responsiveness was tested after 2-24weeks using standardised response mean (SRM). Among the 1548 patients, 64.9% were men, with a mean (SD) age 42.0 (13.4) years. Construct validity ranged from low (age: 0.10) to high (Bath AnkylosingSpondylitisFunctioning Index: 0.71). Internal consistency was high (Cronbach's α of 0.93). The reliability among 578 patients was good (ICC=0.87 (95% CI 0.84 to 0.89)). Responsiveness among 246 patients was moderate-large (SRM=-0.44 for non-steroidal anti-inflammatory drugs, -0.69 for conventional synthetic disease-modifying antirheumatic drug and -0.85 for tumour necrosis factor inhibitor). The smallest detectable change was 3.0. Values ≤5.0 have balanced specificity to distinguish good health as opposed to moderate health, and values ≥12.0 are specific to represent poor health as opposed to moderate health. The ASAS HI proved to be valid, reliable and responsive. It can be used to evaluate the impact of SpA and its treatment on functioning and health. Furthermore, comparison of disease impact between populations is possible. © Article author(s) (or their employer(s) unless otherwise

    The concept of usability has become an increasingly important consideration in the design of all kinds of technology. As more products are aimed at global markets and developed through internationally distributed teams, usability design needs to be addressed in global terms. Interest in usability as a design issue and specialist area of research and education has developed steadily in North America and Europe since the 1980's. However, it is only over the last ten years that it has emerged as a global concern. Global Usability provides an introduction to the important issues in globalizing des

    Aim: hyperhomocysteinaemia (Hhcy) is known to be an independent risk factor for vascular disease. Coronary flow reserve (CFR) measured by positron emission tomography (PET) is a sensitive method to monitor the effects of pharmacologic interventions in Hhcy. We assessed coronary vascular reactivity by PET in patients with coronary artery disease (CAD) dependent on their homocysteine (Hcy) levels before and under high dose folic acid supplementation therapy (FAST). Patients, methods: twelve patients with CAD underwent rest/adenosine 13 N-ammonia PET for quantification of myocardial blood flow (MBF) and CFR before and after nine weeks FAST (10 mg/day). Results: folate levels increased from 21 ± 6 to 210 ± 34 μg/l (+900%, p < 0.0001) while Hcy levels decreased from 12.1 ± 3.6 to 9.1 ± 3.1 μmol/l (-25%; p < 0.01). Global resting MBF remained nearly unchanged after FAST, while stress MBF (from 2.61 ± 0.93 to 3.25 ± 1.15 ml/g/min; p = 0.05) and CFR (from 3.00 ± 0.76 to 3.72 ± 0.93 ml/g/min; p < 0.05; +24%) significantly increased in patients with normal and elevated Hcy levels (cut off 12 μmol/l). An inverse relation was found between Hcy and CFR (R = -0.53; p = 0.08) and between Hcy and MBF at rest (R = -0.62; p < 0.05) at baseline conditions, not persisting after FAST. Conclusion: coronary vascular reactivity con be improved by FAST in patients with CAD and normal or elevated Hcy levels. FAST might lower an increased cardiovascular risk in CAD patients possibly by mechanisms that are not related to Hcy. (orig.)

    To describe the baseline characteristics and treatment of the patients randomized in the PARADIGM-HF (Prospective comparison of ARNi with ACEi to Determine Impact on Global Mortality and morbidity in Heart Failure) trial, testing the hypothesis that the strategy of simultaneously blocking the renin-angiotensin-aldosterone system and augmenting natriuretic peptides with LCZ696 200 mg b.i.d. is superior to enalapril 10 mg b.i.d. in reducing mortality and morbidity in patients with heart failure and reduced ejection fraction. Key demographic, clinical and laboratory findings, along with baseline treatment, are reported and compared with those of patients in the treatment arm of the Studies Of Left Ventricular Dysfunction (SOLVD-T) and more contemporary drug and device trials in heart failure and reduced ejection fraction. The mean age of the 8442 patients in PARADIGM-HF is 64 (SD 11) years and 78% are male, which is similar to SOLVD-T and more recent trials. Despite extensive background therapy with beta-blockers (93% patients) and mineralocorticoid receptor antagonists (60%), patients in PARADIGM-HF have persisting symptoms and signs, reduced health related quality of life, a low LVEF (mean 29 ± SD 6%) and elevated N-terminal-proB type-natriuretic peptide levels (median 1608 inter-quartile range 886-3221 pg/mL). PARADIGM-HF will determine whether LCZ696 is more beneficial than enalapril when added to other disease-modifying therapies and if further augmentation of endogenous natriuretic peptides will reduce morbidity and mortality in heart failure and reduced ejection fraction. © 2014 The Authors.

    Full Text Available Background: Protein energy malnutrition is the major cause of poor prognostic outcome in patients on maintenance hemodialysis (MHD. The assessment of nutritional status in patients on maintenance hemodialysis should be done both subjectively and objectively by integrating clinical, biochemical and anthropometric measurements. A study was conducted to assess the possible correlations between the subjective global assessment-dialysis malnutrition score (SGA-DMS, anthropometric measurements, and biochemical parameters in hemodialysis patients. Methods: The study included 90 patients (55 males and 35 females; age range of 25 to 73 years; mean age 52.62 ± 11.7 years undergoing twice/thrice weekly maintenance hemodialysis for six months and above in the dialysis unit of a tertiary care teaching hospital. The MHD patients were assessed by SGA -DMS, anthropometry and biochemical indicators (serum albumin, iron, ferritin and transferrin of nutritional status. Results: According to the SGA-DMS 54.4 % were moderate to severely malnourished, 31% were mild to moderately nourished and 14.4% were well nourished. There was a highly significant negative correlation between SGA –DMS and serum albumin, iron, transferrin; positive correlation between SGA-DMS and ferritin (P<0.0001. Body mass index, upper arm circumferences, and skin fold thickness had a highly significant negative correlation with SGA-DMS (P<0.001, where as the lean body mass, total body water and the fat free mass had a significant negative correlation (P<0.05. Conclusion: SGA-DMS correlated with anthropometric and biochemical parameters that are indicative of nutritional status. SGA –DMS used in conjunction with other objective nutritional assessment methods may be of greater impact in determining nutritional status of hemodialysis patients.

    Young adults with acute myocardial infarction are a critical group to examine for the purpose of risk factor stratification and modification. In this study we aimed to assess the clinical utility of the adjusted Global AntiphosPholipid Syndrome Score (aGAPSS) for the risk stratification of acute myocardial infarction in a cohort of young patients with antiphospholipid syndrome (APS). The analysis included 83 consecutive APS patients (≤50years old) who presented with arterial or venous thromboembolic events. Data on cardiovascular risk factors and antiphospholipid antibodies (aPL) positivity were retrospectively collected. The aGAPSS was calculated by adding the points corresponding to the risk factors, based on a linear transformation derived from the ß-regression coefficient as follows: 3 for hyperlipidaemia, 1 for arterial hypertension, 5 for aCL IgG/IgM, 4 for anti-b2 glycoprotein I IgG/IgM and 4 for LA. Higher aGAPSS values were observed in patients with acute myocardial infarction when compared to the others [mean aGAPSS 11.9 (S.D. 4.15, range 4-18) Vs. mean aGAPSS 9.2 (S.D. 5.1, range 1-17); T test: psyndrome compared to patients with a history of peripheral or cerebrovascular arterial thrombotic events [mean aGAPSS 11.9 (S.D. 4.15, range 4-18) Vs. mean aGAPSS 6.7 (S.D. 5.7, range 1-17); T test: P<0.005]. The aGAPSS is based upon a quantitative score and could aid risk stratifying APS patients younger than 50years for the likelihood of developing coronary thrombotic events and may guide pharmacological treatment for high-risk patients.

    Autologous hematopoietic cell transplantation (HCT) is a first-line therapy for prolonging survival in patients with light-chain (AL) amyloidosis. Cardiac involvement is the most important determinant of survival. However, patients with advanced cardiac involvement have often been excluded from HCT because of high risk for transplantation-related mortality and poor overall survival. Whether baseline left ventricular global longitudinal strain (GLS) can provide additional risk stratification and predict survival after HCT in this high-risk population remains unclear. The aim of this study was to evaluate the prognostic implication of baseline GLS and the added value of GLS beyond circulating cardiac biomarkers for risk stratification in patients with AL amyloidosis undergoing HCT. Eighty-two patients with newly diagnosed AL amyloidosis who underwent upfront HCT between January 2007 and April 2014 were included in the study. Clinical, echocardiographic, and serum cardiac biomarker data were collected at baseline and 12 months following HCT. GLS measurements were performed using a vendor-independent offline system. The median follow-up time for survivors was 58 months. Sixty-four percent of patients were in biomarker-based Mayo stage II or III. GLS, brain natriuretic peptide, troponin, and mitral E/A ratio were identified as the strongest predictors of survival (P value that best discriminated survivors from nonsurvivors, and the application of this cutoff value provided further mortality risk stratification within each Mayo stage. GLS is a strong predictor of survival in patients with AL amyloidosis undergoing HCT, potentially providing incremental value over serum cardiac biomarkers for risk stratification. GLS should be considered as a standard parameter along with serum cardiac biomarkers when evaluating eligibility for HCT or other investigational therapies.

    To test the efficacy and safety of an integrated treatment based on a pharmaconutritional support, antioxidants, and drugs, all given orally, in a population of advanced cancer patients with cancer-related anorexia/cachexia and oxidative stress. An open early-phase II study was designed according to the Simon two-stage design. The integrated treatment consisted of diet with high polyphenols content (400 mg), antioxidant treatment (300 mg/d alpha-lipoic acid + 2.7 g/d carbocysteine lysine salt + 400 mg/d vitamin E + 30,000 IU/d vitamin A + 500 mg/d vitamin C), and pharmaconutritional support enriched with 2 cans per day (n-3)-PUFA (eicosapentaenoic acid and docosahexaenoic acid), 500 mg/d medroxyprogesterone acetate, and 200 mg/d selective cyclooxygenase-2 inhibitor celecoxib. The treatment duration was 4 months. The following variables were evaluated: (a) clinical (Eastern Cooperative Oncology Group performance status); (b) nutritional [lean body mass (LBM), appetite, and resting energy expenditure]; (c) laboratory [proinflammatory cytokines and leptin, reactive oxygen species (ROS) and antioxidant enzymes]; (d) quality of life (European Organization for Research and Treatment of Cancer QLQ-C30, Euro QL-5D, and MFSI-SF). From July 2002 to January 2005, 44 patients were enrolled. Of these, 39 completed the treatment and were assessable. Body weight increased significantly from baseline as did LBM and appetite. There was an important decrease of proinflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor-alpha, and a negative relationship worthy of note was only found between LBM and IL-6 changes. As for quality of life evaluation, there was a marked improvement in the European Organization for Research and Treatment of Cancer QLQ-C30, Euro QL-5D(VAS), and multidimensional fatigue symptom inventory-short form scores. At the end of the study, 22 of the 39 patients were "responders" or "high responders." The minimum required was 21; therefore, the

    Full Text Available Global Registry of Acute Coronary Events (GRACE risk score and red blood cell distribution width (RDW content can both independently predict major adverse cardiac events (MACEs in patients with acute coronary syndrome (ACS. We investigated the combined predictive value of RDW and GRACE risk score for cardiovascular events in patients with ACS undergoing percutaneous coronary intervention (PCI for the first time. We enrolled 480 ACS patients. During a median follow-up time of 37.2 months, 70 (14.58% patients experienced MACEs. Patients were divided into tertiles according to the baseline RDW content (11.30-12.90, 13.00-13.50, 13.60-16.40. GRACE score was positively correlated with RDW content. Multivariate Cox analysis showed that both GRACE score and RDW content were independent predictors of MACEs (hazard ratio 1.039; 95% confidence interval [CI] 1.024-1.055; p < 0.001; 1.699; 1.294-2.232; p < 0.001; respectively. Furthermore, Kaplan-Meier analysis demonstrated that the risk of MACEs increased with increasing RDW content (p < 0.001. For GRACE score alone, the area under the receiver operating characteristic (ROC curve for MACEs was 0.749 (95% CI: 0.707-0.787. The area under the ROC curve for MACEs increased to 0.805 (0.766-0.839, p = 0.034 after adding RDW content. The incremental predictive value of combining RDW content and GRACE risk score was significantly improved, also shown by the net reclassification improvement (NRI = 0.352, p < 0.001 and integrated discrimination improvement (IDI = 0.023, p = 0.002. Combining the predictive value of RDW and GRACE risk score yielded a more accurate predictive value for long-term cardiovascular events in ACS patients who underwent PCI as compared to each measure alone.

    Immunoglobulin light chain (AL) amyloidosis is a rare plasma cell dyscrasia characterized by the deposition of abnormal amyloid fibrils in multiple organs, thus impairing their function. In the largest cohort studied up to now of 118 CD138-purified plasma cell samples from previously untreated immunoglobulin light chain amyloidosis patients, we assessed in parallel copy number alterations using high-density copy number arrays and interphase fluorescence in situ hybridization (iFISH). We used fluorescence in situ hybridization probes for the IgH translocations t(11;14), t(4;14), and t(14;16) or any other IgH rearrangement as well as numerical aberrations of the chromosome loci 1q21, 8p21, 5p15/5q35, 11q22.3 or 11q23, 13q14, 15q22, 17p13, and 19q13. Recurrent gains included chromosomes 1q (36%), 9 (24%), 11q (24%), as well as 19 (15%). Recurrent losses affected chromosome 13 (29% monosomy) and partial losses of 14q (19%), 16q (14%) and 13q (12%), respectively. In 88% of patients with translocation t(11;14), the hallmark chromosomal aberration in AL amyloidosis, a concomitant gain of 11q22.3/11q23 detected by iFISH was part of the unbalanced translocation der(14)t(11;14)(q13;q32) with the breakpoint in the CCND1/MYEOV gene region. Partial loss of chromosome regions 14q and 16q were significantly associated to gain 1q. Gain 1q21 detected by iFISH almost always resulted from a gain of the long arm of chromosome 1 and not from trisomy 1, whereas deletions on chromosome 1p were rarely found. Overall and event-free survival analysis found a potential adverse prognostic effect of concomitant gain 1q and deletion 14q as well as of deletion 1p. In conclusion, in the first whole genome report of clonal plasma cells in AL amyloidosis, novel aberrations and hitherto unknown potential adverse prognostic effects were uncovered.

    Full Text Available Abstract Background With greater technological developments in the care of musculoskeletal patients, we are entering an era of rapid change in our understanding of the pathophysiology of traumatic injury; assessment and treatment of polytrauma and related disorders; and treatment outcomes. In developed countries, it is very likely that we will have algorithms for the approach to many musculoskeletal disorders as we strive for the best approach with which to evaluate treatment success. This debate article is founded on predictions of future health care needs that are solely based on the subjective inputs and opinions of the world's leading orthopedic surgeons. Hence, it functions more as a forum-based rather than a scientific-based presentation. This exposé was designed to stimulate debate about the emerging patients' needs in the future predicted by leading orthopedic surgeons that provide some hint as to the right direction for orthopedic care and outlines the important topics in this area. Discussion The authors aim to provide a general overview of orthopedic care in a typical developed country setting. However, the regional diversity of the United States and every other industrialized nation should be considered as a cofactor that may vary to some extent from our vision of improved orthopedic and trauma care of the musculoskeletal patient on an interregional level. In this forum, we will define the current and future barriers in developed countries related to musculoskeletal trauma, total joint arthroplasty, patient safety and injuries related to military conflicts, all problems that will only increase as populations age, become more mobile, and deal with political crisis. Summary It is very likely that the future will bring a more biological approach to fracture care with less invasive surgical procedures, flexible implants, and more rapid rehabilitation methods. This international consortium challenges the trauma and implants community to

    We studied 18 patients within 24 hours of an idiopathic transient global amnesia and one month later using 133 Xe et 99m Tc-HMPAO for CBF measurements. Absolute hemispheric CBF obtained with the 133 Xe were initially: (right) = 46.9 ml/mn/100 g (s.d 6.6) and (left) = 47.9 (s.d 6.8). One month later, a significant increase of the right hemispheric CBF occurred (52.0 ± 6.9). Accordingly, absolute CBF increased bilaterally in the cerebellar and temporal regions. Local relative cerebral blood flow ( 99m Tc-HMPAO) allowed to reinforce these findings with increased resolution. They can also provide quantitative values thanks to the 133 Xe calibration.

    In a controlled study of 74 patients with coronary heart disease (KHK) or without provable heart disease the ventricle function at rest and under ergonomic load before and after oral administration of nitrates, respectively placebos was studied with the help of radionuclide ventriculography. Radionuclide ventriculography proved itself thereby as a valuable method of high sensitivity for the recognition of KHK. The stress test increases the sensitivity and allows inferences to be made on the extent of the ischemia. The global function at rest is more a parameter for the functional restriction by infarct scars. A quantitative regional evaluation also makes possible the recognition of minor local changes. The additional study after nitrate administration allows a basis for the extent of reversibility in the stress-dependent functional restriction. The effects of a drug therapy become extrinsically presentable as a result of radionuclide ventriculography. (TRV) [de

    The Institute for Healthcare Improvement encourages use of the Global Trigger Tool to objectively determine and monitor adverse events (AEs). Baylor Health Care System (BHCS) is an integrated healthcare delivery system in North Texas. The Global Trigger Tool was applied to BHCS's eight general acute care hospitals, two inpatient cardiovascular hospitals and two rehabilitation/long-term acute care hospitals. Data were collected from a monthly random sample of charts for each facility for patients discharged between 1 July 2006 and 30 June 2007 by external professional nurse auditors using an MS Access Tool developed for this initiative. In addition to the data elements recommended by Institute for Healthcare Improvement, BHCS developed fields to permit further characterisation of AEs to identify learning opportunities. A structured narrative description of each identified AE facilitated text mining to further characterise AEs. INITIAL FINDINGS: Based on this sample, AE rates were found to be 68.1 per 1000 patient days, or 50.8 per 100 encounters, and 39.8% of admissions were found to have ≥1 AE. Of all AEs identified, 61.2% were hospital-acquired, 10.1% of which were associated with a National Coordinating Council - Medical Error Reporting and Prevention harm score of "H or I" (near death or death). To enhance learning opportunities and guide quality improvement, BHCS collected data-such as preventability and AE source-to characterise the nature of AEs. Data are provided regularly to hospital teams to direct quality initiatives, moving from a general focus on reducing AEs to more specific programmes based on patterns of harm and preventability.

    To examine the association between elevated leukocyte count and hospital mortality and heart failure in patients enrolled in the multinational, observational Global Registry of Acute Coronary Events (GRACE). Elevated leukocyte count is associated with adverse hospital outcomes in patients presenting with acute myocardial infarction (AMI). The association of this prognostic factor with hospital mortality and heart failure in patients with other acute coronary syndromes (ACS) is unclear. We examined the association between admission leukocyte count and hospital mortality and heart failure in 8269 patients presenting with an ACS. This association was examined separately in patients with ST-segment elevation AMI, non-ST-segment elevation AMI, and unstable angina. Leukocyte count was divided into 4 mutually exclusive groups (Q): Q1 12,000. Multiple logistic regression analysis was performed to examine the association between elevated leukocyte count and hospital events while accounting for the simultaneous effect of several potentially confounding variables. Increasing leukocyte count was significantly associated with hospital death (adjusted odds ratio [OR] 2.8, 95% CI 2.1-3.6 for Q4 compared to Q2 [normal range]) and heart failure (OR 2.7, 95% CI 2.2-3.4) for patients presenting with ACS. This association was seen in patients with ST-segment elevation AMI (OR for hospital death 3.2, 95% CI 2.1-4.7; OR for heart failure 2.4, 95% CI 1.8-3.3), non-ST-segment elevation AMI (OR for hospital death 1.9, 95% CI 1.2-3.0; OR for heart failure 1.7, 95% CI 1.1-2.5), or unstable angina (OR for hospital death 2.8, 95% CI 1.4-5.5; OR for heart failure 2.0, 95% CI 0.9-4.4). In men and women of all ages with the spectrum of ACS, initial leukocyte count is an independent predictor of hospital death and the development of heart failure.

    A multi-method strategy has been proposed to understand and improve the safety of primary care. The trigger tool is a relatively new method that has shown promise in American and secondary healthcare settings. It involves the focused review of a random sample of patient records using a series of "triggers" that alert reviewers to potential errors and previously undetected adverse events. To develop and test a global trigger tool to detect errors and adverse events in primary-care records. Trigger tool development was informed by previous research and content validated by expert opinion. The tool was applied by trained reviewers who worked in pairs to conduct focused audits of 100 randomly selected electronic patient records in each of five urban general practices in central Scotland. Review of 500 records revealed 2251 consultations and 730 triggers. An adverse event was found in 47 records (9.4%), indicating that harm occurred at a rate of one event per 48 consultations. Of these, 27 were judged to be preventable (42%). A further 17 records (3.4%) contained evidence of a potential adverse event. Harm severity was low to moderate for most patients (82.9%). Error and harm rates were higher in those aged > or =60 years, and most were medication-related (59%). The trigger tool was successful in identifying undetected patient harm in primary-care records and may be the most reliable method for achieving this. However, the feasibility of its routine application is open to question. The tool may have greater utility as a research rather than an audit technique. Further testing in larger, representative study samples is required.

    In asymptomatic patients with ≥3+ mitral regurgitation and preserved left ventricular (LV) ejection fraction who underwent mitral valve surgery, we sought to discover whether baseline LV global longitudinal strain (LV-GLS) and brain natriuretic peptide provided incremental prognostic utility. Four hundred and forty-eight asymptomatic patients (61±12 years and 69% men) with ≥3+ primary mitral regurgitation and preserved left ventricular ejection fraction, who underwent mitral valve surgery (92% repair) at our center between 2005 and 2008, were studied. Baseline clinical and echocardiographic data (including LV-GLS using Velocity Vector Imaging, Siemens, PA) were recorded. The Society of Thoracic Surgeons score was calculated. The primary outcome was death. Mean Society of Thoracic Surgeons score, left ventricular ejection fraction, mitral effective regurgitant orifice, indexed LV end-diastolic volume, and right ventricular systolic pressure were 4±1%, 62±3%, 0.55±0.2 cm(2), 58±13 cc/m(2), and 37±15 mm Hg, respectively. Forty-five percent of patients had flail. Median log-transformed BNP and LV-GLS were 4.04 (absolute brain natriuretic peptide: 60 pg/dL) and -20.7%. At 7.7±2 years, death occurred in 41 patients (9%; 0% at 30 days). On Cox analysis, a higher Society of Thoracic Surgeons score (hazard ratio 1.55), higher baseline right ventricular systolic pressure (hazard ratio 1.11), more abnormal LV-GLS (hazard ratio 1.17), and higher median log-transformed BNP (hazard ratio 2.26) were associated with worse longer-term survival (all Pright ventricular systolic pressure) provided incremental prognostic utility (χ(2) for longer-term mortality increased from 31-47 to 61; Pleft ventricular ejection fraction who underwent mitral valve surgery, brain natriuretic peptide and LV-GLS provided synergistic risk stratification, independent of established factors. © 2016 American Heart Association, Inc.

    OBJECTIVES To examine Montreal Cognitive Assessment (MoCA) performance in patients with Parkinson’s disease (PD) with “normal” global cognition according to Mini-Mental State Examination (MMSE) score. DESIGN A cross-sectional comparison of the MoCA and the MMSE. SETTING Two movement disorders centers at the University of Pennsylvania and the Philadelphia Veterans Affairs Medical Center. PARTICIPANTS A convenience sample of 131 patients with idiopathic PD who were screened for cognitive and psychiatric complications. MEASUREMENTS Subjects were administered the MoCA and MMSE, and only subjects defined as having a normal age- and education-adjusted MMSE score were included in the analyses (N = 100). As previously recommended in patients without PD, a MoCA score less than 26 was used to indicate the presence of at least mild cognitive impairment (MCI). RESULTS Mean MMSE and MoCA scores ± standard deviation were 28.8 ± 1.1 and 24.9 ± 3.1, respectively. More than half (52.0%) of subjects with normal MMSE scores had cognitive impairment according to their MoCA score. Impairments were seen in numerous cognitive domains, including memory, visuospatial and executive abilities, attention, and language. Predictors of cognitive impairment on the MoCA using univariate analyses were male sex, older age, lower educational level, and greater disease severity; older age was the only predictor in a multivariate model. CONCLUSION Approximately half of patients with PD with a normal MMSE score have cognitive impairment based on the recommended MoCA cutoff score. These results suggest that MCI is common in PD and that the MoCA is a more sensitive instrument than the MMSE for its detection. PMID:19170786

In this paper, I analyse the causes of the global inequality of health and the ethical arguments for and against the need to treat this inequality from the perspective of the global justice. After refusing the arguments against both of the libertarianism and the statism, and after showing the critics both to the approach to the language of human rights and to the poggean proposal to reduce the duties of global justice to negative moral duties, I defend the need to use a sufficiency approach to global justice based in positive moral duties to face the severity and the moral urgency of the global inequalities of health.

    Una de las cuestiones que debería preocupar más a la teoría de la justicia global es la enorme desigualdad de salud que hay en el mundo. En este artículo, se repasan las causas de la desigualdad global de salud y los argumentos éticos a favor y en contra de la necesidad de tratar dicha desigualdad desde la perspectiva de la justicia global. Tras rechazar los argumentos en contra tanto del libertarismo de derechas como del estatalismo, y tras exponer las críticas tanto al lenguaje de los derechos humanos como a la propuesta poggeana de reducir los deberes de la justicia global a deberes morales negativos, defiendo la necesidad de partir de un criterio de justicia global suficientista y basado en los deberes morales positivos para afrontar la gravedad y la urgencia moral que suponen las desigualdades globales de salud.

    Objective. To describe a novel training model used to create a sustainable public health-focused pharmacy residency based in Kenya and to describe the outcomes of this training program on underserved populations. Design. The postgraduate year 2 residency was designed to expose trainees to the unique public health facets of inpatient, outpatient, and community-based care delivery in low and middle-income countries. Public health areas of focus included supply chain management, reproductive health, pediatrics, HIV, chronic disease management, and teaching. Assessment. The outcomes of the residency were assessed based on the number of new clinical programs developed by residents, articles and abstracts written by residents, and resident participation in grant writing. To date, six residents from the United States and eight Kenyan residents have completed the residency. Eleven sustainable patient care services have been implemented as a result of the residency program. Conclusion. This pharmacy residency training model developed accomplished pharmacists in public health pharmacy, with each residency class expanding funding and clinical programming, contributing to curriculum development, and creating jobs.

    Global Mindsets: Exploration and Perspectives seeks to tackle a topic that is relatively new in research and practice, and is considered by many to be critical for firms seeking to conduct global business. It argues that multiple mindsets exist (across and within organizations), that they operate...... in a global context, and that they are dynamic and undergo change and action. Part of the mindset(s) may depend upon place, situation and context where individuals and organizations operate. The book will examine the notion of "mindset" is situational and dynamic, especially in a global setting, why...... it is important for future scholars and managers and how it could be conceptualized. Global Mindsets: Exploration and Perspectives is split into two major sections; the first examines where the literature currently is with respect to the knowledge in the field and what conceptual frameworks guide the thinking...

    Canada's Green Plan strategy for dealing with global warming is being implemented as a multidepartmental partnership involving all Canadians and the international community. Many of the elements of this strategy are built on an existing base of activities predating the Green Plan. Elements of the strategy include programs to limit emissions of greenhouse gases, such as initiatives to encourage more energy-efficient practices and development of alternate fuel sources; studies and policy developments to help Canadians prepare and adapt to climate change; research on the global warming phenomenon; and stimulation of international action on global warming, including obligations arising out of the Framework Convention on Climate Change. All the program elements have been approved, funded, and announced. Major achievements to date are summarized, including improvements in the Energy Efficiency Act, studies on the socioeconomic impacts of global warming, and participation in monitoring networks. Milestones associated with the remaining global warming initiatives are listed

    The International Society for Radiation Oncology (ISRO) is a federation of regional and national societies. These societies include about 80 000 radiation oncologists, physicists and related specialists. The incidence of cancer per year in developing countries is about 0.08 to about 0.2% of the population. In some developed countries, up to 0.5% of the population will be diagnosed with cancer each year - this is a very high figure. You must also look at prevalence: that is, how many of those that have had the diagnosis 'cancer' are still alive. In some developed countries, up to 3% of the population have had the diagnosis 'cancer' at some stage in their life. The projected number of new cases in the year 2000 is five million for developing and five million for developed countries. On the basis of practices exercised today in many advanced developed countries, it is estimated that 50% of these would need radiotherapy. In some countries, up to 60% of cancer cases receive at least one course of radiation treatment. Of course, good quality assurance is a matter of life and death for the patient, and radiation protection and quality assurance are in many situations much the same thing. What can the international societies do in this context? We can try to inform and teach our friends in less developed countries. For this reason, many educational meetings have been organized by the ISRO. The society tries to hold these meetings outside developed areas such as Europe and north America, and to convene them in developing regions of the world, instead. By including experienced teachers from more developed areas, the society seeks to help those who do not yet have all the knowledge they need

    The electrical impedance tomography (EIT)-based global inhomogeneity (GI) index was introduced to quantify tidal volume distribution within the lung. Up to now, the GI index was evaluated for plausibility but the analysis of how it is influenced by various physiological factors is still missing. The aim of our study was to evaluate the influence of proportion of open lung regions measured by EIT on the GI index. A constant low-flow inflation maneuver was performed in 18 acute respiratory distress syndrome (ARDS) patients (58 ± 14 years, mean age ± SD) and 8 lung-healthy patients (41 ± 12 years) under controlled mechanical ventilation. EIT raw data were acquired at 25 scans/s and reconstructed offline. Recruited lung regions were identified as those image pixels of the lung regions within the EIT scans where local impedance amplitudes exceeded 10% of the maximum amplitude during the maneuver. A series of GI indices was calculated during mechanical lung inflation, based on the differential images obtained between different time points. Respiratory system elastance (Ers) values were calculated at 10 lung volume levels during low-flow maneuver. The GI index decreased during low-flow inflation, while the percentage of open lung regions increased. The values correlated highly in both ARDS (r2 = 0.88 ± 0.08, p EIT. The GI index may prove to be a useful EIT-based index to guide ventilation therapy.

    The Clinical Global Impression of Change (CGIC) measures have high utility in clinical practice. However, it is unknown whether the CGIC is valued for assessing premature ejaculation (PE) symptoms and/or the relationship between CGIC and other validated PE patient-reported measures. The study aims to assess the validity of the patient-reported CGIC measure in men with PE and to examine the relationship between CGIC ratings and assessments of control, satisfaction, personal distress, and interpersonal difficulty. Data from a randomized, double-blind, 24-week phase 3 trial in 1,162 men with PE who received dapoxetine (30 mg or 60 mg) or placebo on demand provided the basis for the analysis. Patients were ≥18 years, in a stable monogamous relationship for ≥6 months, met the Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition-Text Revision criteria for PE for ≥6 months, and had an intravaginal ejaculatory latency time (IELT) ≤2 minutes in ≥75% of intercourse episodes. The CGIC asked patients to rate improvement or worsening of their PE compared with the start of the study using a 7-point response scale; other patient-reported measures were control over ejaculation, satisfaction with sexual intercourse, interpersonal difficulty, and personal distress related to ejaculation. Stopwatch-measured IELT was recorded. Associations between CGIC and change in other measures at study end point were assessed. The magnitude of IELT increased for each category of improvement on the CGIC: 1.63, 4.03, and 7.15 minutes for slightly better, better, and much better, respectively. Higher CGIC ratings were correlated with greater improvement in control (r = 0.73), satisfaction (r = 0.62), greater reduction in distress (r = -0.52), and interpersonal difficulty (r = -0.39). Total variance accounted for was 57.4%: control (48.7%), satisfaction (4.5%), IELT (2.8%), and distress (1.15%). The analyses support the validity of the CGIC measure in men with PE. The CGIC

  17. Global gravitational anomalies

    Witten, E.

    1985-01-01

    A general formula for global gauge and gravitational anomalies is derived. It is used to show that the anomaly free supergravity and superstring theories in ten dimensions are all free of global anomalies that might have ruined their consistency. However, it is shown that global anomalies lead to some restrictions on allowed compactifications of these theories. For example, in the case of O(32) superstring theory, it is shown that a global anomaly related to π 7 (O(32)) leads to a Dirac-like quantization condition for the field strength of the antisymmetric tensor field. Related to global anomalies is the question of the number of fermion zero modes in an instanton field. It is argued that the relevant gravitational instantons are exotic spheres. It is shown that the number of fermion zero modes in an instanton field is always even in ten dimensional supergravity. (orig.)

The author draws attention to some new phenomena, particularly, cosmopolitanization of some parts of national elites and a deepening divide between national interests and the private interests of elites as a consequence of financial globalization. Modern mass media, both Russian and foreign, tend to interpret globalization processes exclusively from the position of conformism, and for some of the researchers globalization became the "sacred cow", which one may only worship. Critical analysis of the processes associated with globalization is given a hostile reception. In response to criticism of globalization, one can hear the very same argument: "globalization in inevitable!" Such a state of affairs, the very least, causes perplexity. Some of the world development trends been observed over the past years raise serious concerns about the security and welfare of the peoples of the world.

Design/methodology/approach: – In total, 332 global managers were surveyed from multinational companies operating in Brazil. The mediating effect of job...... satisfaction was tested on the CQ-job performance relationship. Findings: – The findings suggest that job satisfaction transmits the effect of CQ to job performance, such that global managers high in CQ exhibit more job satisfaction in an international setting, and therefore perform better at their jobs....... Practical implications: – Results imply that global managers should increase their CQ in order to improve their job satisfaction and ultimately perform better in an international context.

    Global warming-like deforestation, the ozone hole and the loss of species- has become one of the late 20the century icons of global environmental damage. The threat, is not the reality, of such a global climate change has motivated governments. businesses and environmental organisations, to take serious action ot try and achieve serious control of the future climate. This culminated last December in Kyoto in the agreement for legally-binding climate protocol.

    Full Text Available The purpose of the study was to evaluate the long-term clinical tracking of magnetically labeled stem cells after intracerebroventricular transplantation as well as to investigate in vitro feasibility for magnetic guidance of cell therapy within large fluid compartments.After approval by our Institutional Review Board, an 18-month-old patient, diagnosed as being in a vegetative state due to global cerebral ischemia, underwent cell transplantation to the frontal horn of the lateral ventricle, with umbilical cord blood-derived stem cells labeled with superparamagnetic iron oxide (SPIO contrast agent. The patient was followed over 33 months with clinical examinations and MRI. To evaluate the forces governing the distribution of cells within the fluid compartment of the ventricular system in vivo, a gravity-driven sedimentation assay and a magnetic field-driven cell attraction assay were developed in vitro.Twenty-four hours post-transplantation, MR imaging (MRI was able to detect hypointense cells in the occipital horn of the lateral ventricle. The signal gradually decreased over 4 months and became undetectable at 33 months. In vitro, no significant difference in cell sedimentation between SPIO-labeled and unlabeled cells was observed (p = NS. An external magnet was effective in attracting cells over distances comparable to the size of human lateral ventricles.MR imaging of SPIO-labeled cells allows monitoring of cells within lateral ventricles. While the initial biodistribution is governed by gravity-driven sedimentation, an external magnetic field may possibly be applied to further direct the distribution of labeled cells within large fluid compartments such as the ventricular system.

    This study used data from different sources to identify the extent of the unmet need for postprandial glycemic control in patients with type 2 diabetes mellitus (T2DM) after the initiation of basal insulin therapy in Europe, Asia Pacific, the United States, and Latin America. Different levels of evidence were used as available for each country/region, with data extracted from seven randomized controlled trials (RCTs), three clinical trial registries (CTRs), and three electronic medical record (EMR) databases. Glycemic status was categorized as "well controlled" (glycated hemoglobin [HbA 1c ] at target [130/140 mg/dL, depending on country-specific recommendations]), or "uncontrolled" (both FPG and HbA 1c above target). Predictor factors were identified from the RCT data set using logistic regression analysis. RCT data showed that 16.9% to 28.0%, 42.7% to 54.4%, and 16.9% to 38.1% of patients with T2DM had well-controlled glycemia, residual hyperglycemia, and uncontrolled hyperglycemia, respectively. In CTRs, respective ranges were 21.8% to 33.6%, 31.5% to 35.6%, and 30.7% to 46.8%, and in EMR databases were 4.4% to 21.0%, 23.9% to 31.8%, and 53.6% to 63.8%. Significant predictor factors of residual hyperglycemia identified from RCT data included high baseline HbA 1c (all countries/regions except Brazil), high baseline FPG (United Kingdom/Japan), longer duration of diabetes (Brazil), and female sex (Europe/Latin America). Irrespective of intrinsic differences between data sources, 24% to 54% of patients with T2DM globally had residual hyperglycemia with HbA 1c not at target, despite achieving FPG control, indicating a significant unmet need for postprandial glycemic control. © 2016 The Authors.

    IYA2009 is a global collaboration between almost 140 nations and more than 50 international organisations sharing the same vision. Besides the common brand, mission, vision and goals, IAU established eleven cornerstones programmes to support the different IYA2009 stakeholder to organize events, activities under a common umbrella. These are global activities centred on specific themes and are aligned with IYA2009's main goals. Whether it is the support and promotion of women in astronomy, the preservation of dark-sky sites around the world or educating and explaining the workings of the Universe to millions, the eleven Cornerstones are key elements in the success of IYA2009. However, the process of implementing global projects across cultural boundaries is challenging and needs central coordination to preserve the pre-established goals. During this talk we will examine the ups and downs of coordinating such a project and present an overview of the principal achievements for the Cornerstones so far.

  14. Global rotation

    Rosquist, K.

    1980-01-01

    Global rotation in cosmological models is defined on an observational basis. A theorem is proved saying that, for rigid motion, the global rotation is equal to the ordinary local vorticity. The global rotation is calculated in the space-time homogeneous class III models, with Godel's model as a special case. It is shown that, with the exception of Godel's model, the rotation in these models becomes infinite for finite affine parameter values. In some directions the rotation changes sign and becomes infinite in a direction opposite to the local vorticity. The points of infinite rotation are identified as conjugate points along the null geodesics. The physical interpretation of the infinite rotation is discussed, and a comparison with the behaviour of the area distance at conjugate points is given. (author)

    Full Text Available Finding the anachronisms and the failures of the present globalization, as well as the vitiated system of world-wide government, has stimulated the debates regarding the identification of a more equitable form of globalization to favor the acceleration of the economic increase and the reduction of poverty.The deficiency of the present international economic institutions, especially the lack of transparency and democratic responsibility, claims back with acuteness the reformation of the architecture of the international institutional system and the promotion of those economical policies which must ensure the stability world-wide economy and the amelioration of the international equity.

    The multivariate technique of factor analysis is used to combine several indicators of economic integration and international transactions into a single measure or index of globalization. The index is an alternative to the simple measure of openness based on trade, and it produces a ranking of countries over time for 23 OECD countries. Ireland is ranked as the most globalized country during the 1990?s, while the UK was at the top during the 1980?s. Some of the most notable changes in the rank...

    Secondary intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are closely related to fluid resuscitation. IAH causes major deterioration of the cardiac function by affecting preload, contractility and afterload. The aim of this review is to discuss the different interactions between IAH, ACS and resuscitation, and to explore a new hypothesis with regard to damage control resuscitation, permissive hypotension and global increased permeability syndrome. Review of the relevant literature via PubMed search. The recognition of the association between the development of ACS and resuscitation urged the need for new approach in traumatic shock management. Over a decade after wide spread application of damage control surgery damage control resuscitation was developed. DCR differs from previous resuscitation approaches by attempting an earlier and more aggressive correction of coagulopathy, as well as metabolic derangements like acidosis and hypothermia, often referred to as the 'deadly triad' or the 'bloody vicious cycle'. Permissive hypotension involves keeping the blood pressure low enough to avoid exacerbating uncontrolled haemorrhage while maintaining perfusion to vital end organs. The potential detrimental mechanisms of early, aggressive crystalloid resuscitation have been described. Limitation of fluid intake by using colloids, hypertonic saline (HTS) or hyperoncotic albumin solutions have been associated with favourable effects. HTS allows not only for rapid restoration of circulating intravascular volume with less administered fluid, but also attenuates post-injury oedema at the microcirculatory level and may improve microvascular perfusion. Capillary leak represents the maladaptive, often excessive, and undesirable loss of fluid and electrolytes with or without protein into the interstitium that generates oedema. The global increased permeability syndrome (GIPS) has been articulated in patients with persistent systemic inflammation failing

    In this chapter, a discussion is presented of the global warming problem and activities contributing to the formation of acid rain, urban smog and to the depletion of the ozone layer. Globally, about two-thirds of anthropogenic carbon dioxide emissions arise from fossil-fuel burning; the rest arise primarily from deforestation. Chlorofluorocarbons are the second largest contributor to global warming, accounting for about 20% of the total. The third largest contributor is methane, followed by ozone and nitrous oxide. A study of current activities in the US that contribute to global warming shows the following: electric power plants account for about 33% of carbon dioxide emissions; motor vehicles, planes and ships (31%); industrial plants (24%); commercial and residential buildings (11%)

    The aim of this study is to compare gene expression profiles in RNA isolated from pancreatic ductal juice with the RNA expression profiles of the same genes from matched intra-operative tissue samples from pancreatic tumours. Intra-operative sampling of pancreatic juice and collection of matched tissue samples was undertaken in patients undergoing pancreatoduodenectomy for clinically suspected pancreatic cancer and a precursor lesion, main-duct intraductal papillary mucinous neoplasm. RNA was isolated and Poly A PCR was used to globally amplify the RNA. Real-time polymerase chain reaction (RT-PCR) was used to measure expression levels of 17 genes selected from microarray studies. Spearman's rank correlation test was used to examine the relationship of gene expression between pancreatic juice and tissue. The study was approved by Regional Ethics Committee. Mesothelin (MSLN) showed significant correlation (p cDNA using poly A PCR is technically feasible. Application of the technique to non-invasively obtained pancreatic juice during endoscopic assessment of tumours and the use of gene arrays of cancer indicator genes are the next steps in development of this technique.

    Toward the future, the petroleum could stop to be the main energy source in the world and the oil companies will only survive if they are adjusted to the new winds that blow in the general energy sector. It will no longer be enough to be the owner of the resource (petroleum or gas) so that a company subsists and be profitable in the long term. The future, it will depend in great measure of the vision with which the oil companies face the globalization concept that begins to experience the world in the energy sector. Concepts like globalization, competition, integration and diversification is something that the companies of the hydrocarbons sector will have very present. Globalization means that it should be been attentive to what happens in the world, beyond of the limits of its territory, or to be caught by competitive surprises that can originate in very distant places. The search of cleaner and friendlier energy sources with the means it is not the only threat that it should fear the petroleum. Their substitution for electricity in the big projects of massive transport, the technology of the communications, the optic fiber and the same relationships with the aboriginal communities are aspects that also compete with the future of the petroleum

  10. Bacteriophages show promise as antimicrobial agents.

    Alisky, J; Iczkowski, K; Rapoport, A; Troitsky, N

    1998-01-01

    The emergence of antibiotic-resistant bacteria has prompted interest in alternatives to conventional drugs. One possible option is to use bacteriophages (phage) as antimicrobial agents. We have conducted a literature review of all Medline citations from 1966-1996 that dealt with the therapeutic use of phage. There were 27 papers from Poland, the Soviet Union, Britain and the U.S.A. The Polish and Soviets administered phage orally, topically or systemically to treat a wide variety of antibiotic-resistant pathogens in both adults and children. Infections included suppurative wound infections, gastroenteritis, sepsis, osteomyelitis, dermatitis, empyemas and pneumonia; pathogens included Staphylococcus, Streptococcus, Klebsiella, Escherichia, Proteus, Pseudomonas, Shigella and Salmonella spp. Overall, the Polish and Soviets reported success rates of 80-95% for phage therapy, with rare, reversible gastrointestinal or allergic side effects. However, efficacy of phage was determined almost exclusively by qualitative clinical assessment of patients, and details of dosages and clinical criteria were very sketchy. There were also six British reports describing controlled trials of phage in animal models (mice, guinea pigs and livestock), measuring survival rates and other objective criteria. All of the British studies raised phage against specific pathogens then used to create experimental infections. Demonstrable efficacy against Escherichia, Acinetobacter, Pseudomonas and Staphylococcus spp. was noted in these model systems. Two U.S. papers dealt with improving the bioavailability of phage. Phage is sequestered in the spleen and removed from circulation. This can be overcome by serial passage of phage through mice to isolate mutants that resist sequestration. In conclusion, bacteriophages may show promise for treating antibiotic resistant pathogens. To facilitate further progress, directions for future research are discussed and a directory of authors from the reviewed

    Carbapenem-resistant Gram-negative bacteria are recognized as a cause of difficult-to-treat infections associated with high mortality. To perform a systematic review of currently available data on distribution, characteristics and outcome associated with carbapenem-resistant bloodstream infections in adult neutropenic patients. Included studies were identified through Medline, Embase and Cochrane databases between January 1995 and April 2016. Random effect meta-analysis was used to quantify the association between carbapenem resistance and mortality and between carbapenem exposure and resistance. A total of 30 studies from 21 countries were included. Overall carbapenem resistance varied from 2% to 53% (median 9%) among studies. Infections due to carbapenem-resistant Pseudomonas spp . were reported in 18 (60%) studies showing high median resistance rates (44% of all carbapenem-resistant Gram-negatives and 19% of Pseudomonas isolates). Resistance of Enterobacteriaceae was less commonly reported and bloodstream infections due to carbapenem-resistant Klebsiella spp. were mainly documented from endemic areas (Greece, Italy, Israel). Carbapenem resistance in Acinetobacter spp. was reported in 9 (30%) studies (median resistance 58% of Acinetobacter isolates). Mortality rates ranged from 33% to 71% (median 50%) in patients with carbapenem-resistant infections. Carbapenem resistance appeared to correlate with mortality (OR 4.89, 95% CI 3.30-7.26) and previous exposure to carbapenems (OR 4.63, 95% CI 3.08-6.96). Carbapenem resistance represents a threat to neutropenic patients. In this group, resistance is likely promoted by previous carbapenem use and leads to high mortality rates. The knowledge of resistance patterns is crucial and can direct clinicians in the use of alternatives to carbapenem-based regimens. © The Author 2016.

  14. Global safety

    2010-08-01

    Full Text Available Global Safety is a container concept referring to various threats such as HIV/Aids, floods and terrorism; threats with different causes and different effects. These dangers threaten people, the global economy and the slity of states. Policy making for this kind of threats often lack an overview of the real causes and the interventions are based on a too shallow analysis of the problem, mono-disciplinary and focus mostly only on the effects. It would be more appropriate to develop policy related to these issues by utilizing the approaches, methods and tools that have been developed for complex societal problems. Handling these complex societal problems should be done multidisciplinary instead of mono-disciplinary. In order to give politicians the opportunity to handle complex problems multidisciplinary, multidisciplinary research institutes should be created. These multidisciplinary research institutes would provide politicians with better approaches to handle this type of problem. In these institutes the knowledge necessary for the change of these problems can be created through the use of the Compram methodology which has been developed specifically for handling complex societal problems. In a six step approach, experts, actors and policymakers discuss the content of the problem and the possible changes. The framework method uses interviewing, the Group Decision Room, simulation models and scenario's in a cooperative way. The methodology emphasizes the exchange of knowledge and understanding by communication among and between the experts, actors and politicians meanwhile keeping emotion in mind. The Compram methodology will be further explained in relation to global safety in regard to terrorism, economy, health care and agriculture.

With the advent of the NORSOK (Forum for development and operation) cost reduction programme and a specific focus on key sectors of the market, the Norwegian oil industry is beginning to market its considerable technological achievements internationally. Obviously, the good fortune of having tested this technology in a very demanding domestic arena means that Norwegian offshore support companies, having succeeded at home, are perfectly poised to export their expertise to the international sector. Drawing on the traditional strengths of the country's maritime heritage, with mobile rig and specialized vessel business featuring strongly, other key technologies have been developed. 5 figs., 1 tab

  17. Measurement of global and regional left ventricular performance with isotope technique in coronary heart disease

    International Nuclear Information System (INIS)

    Bostroem, P.-A.; Svensson, M.; Lilja, B.

    1988-01-01

    To evaluate left ventricular function in coronary artery disease, radionuclide measurements of global and regional ejection fraction (EF), regional wall motion and phase analyses of left ventricular contraction were performed by equilibrium technique, using sup(99m)Tc. One group of patients with angina pectoris and one group with myocardial infarction were compared with a control group. All above-mentioned parameters significantly separated the infarction group from the reference group both at rest and during work, while the group of patients with angina pectoris showed disturbances mainly during work, such as impaired ability to increase global and regional ejection fraction and regional wall motion. Adding regional analysis and phase analysis to the global EF determination increases the possibility of studying the left ventricular function. However, this addition has a limited value in detecting impaired left ventricular function compared to the determination of just global EF in patients with angina pectoris and in patients with myocardial infarction.

    Summary Background Worldwide data for cancer survival are scarce. We aimed to initiate worldwide surveillance of cancer survival by central analysis of population-based registry data, as a metric of the effectiveness of health systems, and to inform global policy on cancer control. Methods Individual tumour records were submitted by 279 population-based cancer registries in 67 countries for 25·7 million adults (age 15–99 years) and 75 000 children (age 0–14 years) diagnosed with cancer during 1995–2009 and followed up to Dec 31, 2009, or later. We looked at cancers of the stomach, colon, rectum, liver, lung, breast (women), cervix, ovary, and prostate in adults, and adult and childhood leukaemia. Standardised quality control procedures were applied; errors were corrected by the registry concerned. We estimated 5-year net survival, adjusted for background mortality in every country or region by age (single year), sex, and calendar year, and by race or ethnic origin in some countries. Estimates were age-standardised with the International Cancer Survival Standard weights. Findings 5-year survival from colon, rectal, and breast cancers has increased steadily in most developed countries. For patients diagnosed during 2005–09, survival for colon and rectal cancer reached 60% or more in 22 countries around the world; for breast cancer, 5-year survival rose to 85% or higher in 17 countries worldwide. Liver and lung cancer remain lethal in all nations: for both cancers, 5-year survival is below 20% everywhere in Europe, in the range 15–19% in North America, and as low as 7–9% in Mongolia and Thailand. Striking rises in 5-year survival from prostate cancer have occurred in many countries: survival rose by 10–20% between 1995–99 and 2005–09 in 22 countries in South America, Asia, and Europe, but survival still varies widely around the world, from less than 60% in Bulgaria and Thailand to 95% or more in Brazil, Puerto Rico, and the USA.

  1. Global catalog of earthquake rupture velocities shows anticorrelation between stress drop and rupture velocity

    Science.gov (United States)

    Chounet, Agnès; Vallée, Martin; Causse, Mathieu; Courboulex, Françoise

    2018-05-01

    Application of the SCARDEC method provides the apparent source time functions together with seismic moment, depth, and focal mechanism, for most of the recent earthquakes with magnitude larger than 5.6-6. Using this large dataset, we have developed a method to systematically invert for the rupture direction and average rupture velocity Vr, when unilateral rupture propagation dominates. The approach is applied to all the shallow (z earthquakes of the catalog over the 1992-2015 time period. After a careful validation process, rupture properties for a catalog of 96 earthquakes are obtained. The subsequent analysis of this catalog provides several insights about the seismic rupture process. We first report that up-dip ruptures are more abundant than down-dip ruptures for shallow subduction interface earthquakes, which can be understood as a consequence of the material contrast between the slab and the overriding crust. Rupture velocities, which are searched without any a-priori up to the maximal P wave velocity (6000-8000 m/s), are found between 1200 m/s and 4500 m/s. This observation indicates that no earthquakes propagate over long distances with rupture velocity approaching the P wave velocity. Among the 23 ruptures faster than 3100 m/s, we observe both documented supershear ruptures (e.g. the 2001 Kunlun earthquake), and undocumented ruptures that very likely include a supershear phase. We also find that the correlation of Vr with the source duration scaled to the seismic moment (Ts) is very weak. This directly implies that both Ts and Vr are anticorrelated with the stress drop Δσ. This result has implications for the assessment of the peak ground acceleration (PGA) variability. As shown by Causse and Song (2015), an anticorrelation between Δσ and Vr significantly reduces the predicted PGA variability, and brings it closer to the observed variability.

  4. Global teaching of global seismology

    Stein, S.; Wysession, M.

    2005-12-01

    Our recent textbook, Introduction to Seismology, Earthquakes, & Earth Structure (Blackwell, 2003) is used in many countries. Part of the reason for this may be our deliberate attempt to write the book for an international audience. This effort appears in several ways. We stress seismology's long tradition of global data interchange. Our brief discussions of the science's history illustrate the contributions of scientists around the world. Perhaps most importantly, our discussions of earthquakes, tectonics, and seismic hazards take a global view. Many examples are from North America, whereas others are from other areas. Our view is that non-North American students should be exposed to North American examples that are type examples, and that North American students should be similarly exposed to examples elsewhere. For example, we illustrate how the Euler vector geometry changes a plate boundary from spreading, to strike-slip, to convergence using both the Pacific-North America boundary from the Gulf of California to Alaska and the Eurasia-Africa boundary from the Azores to the Mediterranean. We illustrate diffuse plate boundary zones using western North America, the Andes, the Himalayas, the Mediterranean, and the East Africa Rift. The subduction zone discussions examine Japan, Tonga, and Chile. We discuss significant earthquakes both in the U.S. and elsewhere, and explore hazard mitigation issues in different contexts. Both comments from foreign colleagues and our experience lecturing overseas indicate that this approach works well. Beyond the specifics of our text, we believe that such a global approach is facilitated by the international traditions of the earth sciences and the world youth culture that gives students worldwide common culture. For example, a video of the scene in New Madrid, Missouri that arose from a nonsensical earthquake prediction in 1990 elicits similar responses from American and European students.

    Concurrent chemoradiotherapy (CRT) for esophageal cancer is expected to achieve adequate quality of life (QOL) and to improve the survival of patients. As a QOL-oriented therapy for esophageal cancer, concurrent CRT with tegafur·gimestat·otastat potassium (TS-1)/nedaplatin (CDGP) was developed and evaluated. Between June 2001 and September 2002, 18 patients with esophageal cancer were enrolled in a clinical study of concurrent CRT with TS-1/CDGP. To evaluate the impact of treatment on the QOL, the patients were asked to answer QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs (QOL-ACD) before and after therapy. The response rate was 66.7%, with a complete response occurring in 9 (50.0%) of the 18 patients. Patients with improved global, functional, or mental QOL after therapy showed or tended to show a significant, longer survival. Compared to patients previously treated by the same regimen with 5-fluorouracil (5-FU) instead of TS-1, those receiving the present therapy were able to leave hospital more frequently during treatment. TS-1/CDGP-based CRT for esophageal cancer exhibited comparable antitumor activity and survival benefit as with standard 5-FU/cisplatin (CDDP)-based CRT without causing serious side-effects. The patients receiving the present therapy seemed to have a better chance of maintaining their QOL. (author)

    Any global view of landforms must include an evaluation of the link between plate tectonics and geomorphology. To explain the broad features of the continents and ocean floors, a basic distinction between the tectogene and cratogene part of the Earth's surface must be made. The tectogene areas are those that are dominated by crustal movements, earthquakes and volcanicity at the present time and are essentially those of the great mountain belts and mid ocean ridges. Cratogene areas comprise the plate interiors, especially the old lands of Gondwanaland and Laurasia. Fundamental as this division between plate margin areas and plate interiors is, it cannot be said to be a simple case of a distinction between tectonically active and stable areas. Indeed, in terms of megageomorphology, former plate margins and tectonic activity up to 600 million years ago have to be considered.

    This article considers the challenges posed by the declining orders in the plant engineering and contracting business in Germany, the need to remain competitive, and essential preconditions for mastering the challenge. The change in engineering approach is illustrated by the building of a methanol plant in Argentina by Lurgi with the basic engineering completed in Frankfurt with involvement of key personnel from Poland, completely engineered subsystems from a Brazilian subsupplier, and detailed engineering work in Frankfurt. The production of methanol from natural gas using the LurgiMega/Methanol process is used as a typical example of the industrial plant construction sector. The prerequisites for successful global engineering are listed, and error costs in plant construction, possible savings, and process intensification are discussed

    'Global warming' is a phrase that refers to the effect on the climate of human activities, in particular the burning of fossil fuels (coal, oil and gas) and large-scale deforestation, which cause emissions to the atmosphere of large amounts of 'greenhouse gases', of which the most important is carbon dioxide. Such gases absorb infrared radiation emitted by the Earth's surface and act as blankets over the surface keeping it warmer than it would otherwise be. Associated with this warming are changes of climate. The basic science of the 'greenhouse effect' that leads to the warming is well understood. More detailed understanding relies on numerical models of the climate that integrate the basic dynamical and physical equations describing the complete climate system. Many of the likely characteristics of the resulting changes in climate (such as more frequent heat waves, increases in rainfall, increase in frequency and intensity of many extreme climate events) can be identified. Substantial uncertainties remain in knowledge of some of the feedbacks within the climate system (that affect the overall magnitude of change) and in much of the detail of likely regional change. Because of its negative impacts on human communities (including for instance substantial sea-level rise) and on ecosystems, global warming is the most important environmental problem the world faces. Adaptation to the inevitable impacts and mitigation to reduce their magnitude are both necessary. International action is being taken by the world's scientific and political communities. Because of the need for urgent action, the greatest challenge is to move rapidly to much increased energy efficiency and to non-fossil-fuel energy sources

    Competition among multinationals these days is likely to be a three-dimensional game of global chess: The moves an organization makes in one market are designed to achieve goals in another in ways that aren't immediately apparent to its rivals. The authors--all management professors-call this approach "competing under strategic interdependence," or CSI. And where this interdependence exists, the complexity of the situation can quickly overwhelm ordinary analysis. Indeed, most business strategists are terrible at anticipating the consequences of interdependent choices, and they're even worse at using interdependency to their advantage. In this article, the authors offer a process for mapping the competitive landscape and anticipating how your company's moves in one market can influence its competitive interactions in others. They outline the six types of CSI campaigns--onslaughts, contests, guerrilla campaigns, feints, gambits, and harvesting--available to any multiproduct or multimarket corporation that wants to compete skillfully. They cite real-world examples such as the U.S. pricing battle Philip Morris waged with R.J. Reynolds--not to gain market share in the domestic cigarette market but to divert R.J. Reynolds's resources and attention from the opportunities Philip Morris was pursuing in Eastern Europe. And, using data they collected from their studies of consumer-products companies Procter & Gamble and Unilever, the authors describe how to create CSI tables and bubble charts that present a graphical look at the competitive landscape and that may uncover previously hidden opportunities. The CSI mapping process isn't just for global corporations, the authors explain. Smaller organizations that compete with a portfolio of products in just one national or regional market may find it just as useful for planning their next business moves.

  11. A Global Perspective

    Summary The emergence of global history has been one of the more notable features of academic history over the past three decades. Although historians of disease were among the pioneers of one of its earlier incarnations—world history—the recent “global turn” has made relatively little impact on histories of health, disease, and medicine. Most continue to be framed by familiar entities such as the colony or nation-state or are confined to particular medical “traditions.” This article aims to show what can be gained from taking a broader perspective. Its purpose is not to replace other ways of seeing or to write a new “grand narrative” but to show how transnational and transimperial approaches are vital to understanding some of the key issues with which historians of health, disease, and medicine are concerned. Moving on from an analysis of earlier periods of integration, the article offers some reflections on our own era of globalization and on the emerging field of global health. PMID:26725408

    Patient satisfaction is an important issue in positioning ambulatory medical services. An effective patient satisfaction measurement program not only helps hospital managers improve the quality of clinical and administrative activities, but also helps the hospital remain viable in increasingly competitive markets. A method for the design and measurement of patient satisfaction with outpatient Endoscopy Lab services is described in this article. The survey focuses on the sequence of events experienced by the patient. Outcome measures of primary interest include global patient satisfaction and the likelihood of using the service again if given a choice. Analysis of patient responses shows that global satisfaction with the outpatient experience is positively associated with service return intention. Additional analysis shows that facility cleanliness, privacy and nurse attention are most strongly associated with global patient satisfaction. Results underscore the importance of various service attributes on patient satisfaction and return intention and of the need to further expand the uses of patient satisfaction measurement in the outpatient Endoscopy Lab.

    Medical mobilities offer both opportunities and challenges. This tension follows the same ratio as many other historic fora, but offers at the same time a sustainable equilibrium. Multi-disciplines are, therefore, the key to the medical lifeworld for the global health and well-being of transnational health users around the globe.

    Recent data suggest that early symptoms may be related to cortex alterations in CADASIL (Cerebral Autosomal-Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy), a monogenic model of cerebral small vessel disease (SVD). The aim of this study was to investigate cortical alterations using both high-resolution T2* acquisitions obtained with 7 Tesla MRI and structural T1 images with 3 Tesla MRI in CADASIL patients with no or only mild symptomatology (modified Rankin's scale ≤1 and Mini Mental State Examination (MMSE) ≥24). Complete reconstructions of the cortex using 7 Tesla T2* acquisitions with 0.7 mm isotropic resolution were obtained in 11 patients (52.1±13.2 years, 36% male) and 24 controls (54.8±11.0 years, 42% male). Seven Tesla T2* within the cortex and cortical thickness and morphology obtained from 3 Tesla images were compared between CADASIL and control subjects using general linear models. MMSE, brain volume, cortical thickness and global sulcal morphology did not differ between groups. By contrast, T2* measured by 7 Tesla MRI was significantly increased in frontal, parietal, occipital and cingulate cortices in patients after correction for multiple testing. These changes were not related to white matter lesions, lacunes or microhemorrhages in patients having no brain atrophy compared to controls. Seven Tesla MRI, by contrast to state of the art post-processing of 3 Tesla acquisitions, shows diffuse T2* alterations within the cortical mantle in CADASIL whose origin remains to be determined.

    Recent political events across the world suggest a retrenchment from globalization and a possible increase in parochialism. This inward-looking threat from parochialism occurs just as the global community faces growing challenges that require trans-national cooperation. In this research, we question if strong identification with an in-group necessarily leads to parochialism and ultimately is detrimental to global cooperation. Building on research on global social identification, we explore whether strong local identification can expand in inclusiveness to global identification, and among whom this is likely to happen. The results of our global public goods study - conducted in South Korea and the United States - show that high levels of social identification with a local group can extend to the global collective, particularly for individuals who are also high in concern-for-others. Furthermore, this identification translates into behavior that benefits the global, anonymous group at a cost to oneself. These results shed light on how to avoid the trap of parochialism and instead engender cooperative behavior with the broader global community.

    Full Text Available The objective of the audit is to determine the prevalence of malnutrition in maintenance peritoneal dialysis (MPD patients in the Top End of the Northern Territory, using the modified Subjective Global Assessment (SGA tool. Methods: The audit was conducted in an outpatients setting. Approximately 75% of PD patients in the Top End Renal service are represented by Aboriginal and Torres Strait Island people. The study population was MPD patients in the Top End Renal Service (TERS of the Northern Territory, from January 1st 2010 to December 31st 2010. Results were compared to malnutrition rates found in the 2008/09 the audit of MPD patients in the TERS. The SGA’s were performed by the renal Dietitian as part of the standard dietetic support of MPD patients. SGA scores were collected from patient medical charts. Results: Patients were classified into one of three categories, based on their SGA score (A Well-nourished; (B Mild- Moderate Malnutrition, (C Severe malnutrition. Malnutrition (B or C was detected in 10% of PD patients, compared to the 2008/09 audit where 76% of MPD patients had some degree of malnutrition. Summary: These results were much lower than malnutrition rates (76% in the MPD patients audited in 2008/09. A number of factors affecting the PD service after the 2008/09 audit could explain the decrease in malnutrition rates including the implementation of free oral nutrition supplements to MPD patients, development of service wide culturally appropriate education resources used in the pre-dialysis and dialysis stage. Future research into the correlation between improved peritonitis rates and decreased malnutrition rates in the population are warranted.

    Survival is analyzed in patients with glioblastoma treated with hypofractionated radiation therapy at Hospital Mexico. The characteristics of the patients are determined within the study. Survival is stableshed in patients who have received hypofractionated regimen. Functional status according to ECOG scale and Karnofsky index is known prior to radiotherapy. The degree of resection to which these patients were submitted is diagnosed before being referred to radiotherapy. The RPA scale adapted from the EORTC of patients is related to overall survival. The mean survival time of the patients have been 5,8 months, and a greater overall survival in the first 6 months. Survival has been more favorable for patients with predicted RPA IV, those older than 60 years and with a degree of complete resection [es

    The poster presented will give an overview of a study towards a "Space Road Show". The topic of this show is space science. The target group is adolescents, aged 12 to 15, at Dutch high schools. The show and its accompanying experiments would be supported with suitable educational material. Science teachers at schools can decide for themselves if they want to use this material in advance, afterwards or not at all. The aims of this outreach effort are: to motivate students for space science and engineering, to help them understand the importance of (space) research, to give them a positive feeling about the possibilities offered by space and in the process give them useful knowledge on space basics. The show revolves around three main themes: applications, science and society. First the students will get some historical background on the importance of space/astronomy to civilization. Secondly they will learn more about novel uses of space. On the one hand they will learn of "Views on Earth" involving technologies like Remote Sensing (or Spying), Communication, Broadcasting, GPS and Telemedicine. On the other hand they will experience "Views on Space" illustrated by past, present and future space research missions, like the space exploration missions (Cassini/Huygens, Mars Express and Rosetta) and the astronomy missions (Soho and XMM). Meanwhile, the students will learn more about the technology of launchers and satellites needed to accomplish these space missions. Throughout the show and especially towards the end attention will be paid to the third theme "Why go to space"? Other reasons for people to get into space will be explored. An important question in this is the commercial (manned) exploration of space. Thus, the questions of benefit of space to society are integrated in the entire show. It raises some fundamental questions about the effects of space travel on our environment, poverty and other moral issues. The show attempts to connect scientific with

  3. Compromised Global and Regional Cerebral Blood Flow in Congestive Heart Failure

    It has been known that cerebral perfusion is maintained in patients with congestive heart failure (CHF) by a complex series of compensatory mechanisms. However cognitive impairment is a common problem experienced by patients with CHF and may result from deranged cerebral perfusion. We prospectively investigated the global and regional CBF of patients with CHF and compared the results with that of normal controls. Thirty two patients (M/F: 22/10, 4211 yr) with CHF (LVEF=218.1%) and 10 healthy controls (M/F: 6/4, 398 yr) were prospectively studied. No patients had cerebrovascular disease or other disease affecting cognitive function. All patients and normal controls underwent radionuclide angiography including cerebral hemispheres and aortic arch, and brain perfusion SPECT using Tc-99m ECD. Global CBF was measured non-invasively by the application of Patlak plot graphical analysis. Quantitative rCBF images were obtained from SPECT image using global CBF values, regional/global count ratios, and Lassen's linearization correction algorithm. Difference of regional CBF between CHF and normal control were assessed using a SPM99 without global count normalization (uncorrected p<0.0001, extent threshold>100 voxels). Global CBF (41.54.7 ml/min/100g) of the patients with CHF were significantly lower than those (49.15.7 ml/min/100g) of controls (p<0.001). Regional CBF was significantly decreased in frontal, temporal and parietal neocortex of both cerebral hemispheres compared to normal controls. Regional rCBF of basal ganglia, thalamus, and brain stem were preserved, even though global CBF was variably compromised. Our study show that global CBF is significantly decreased in CHF and regional CBF of frontal, parietal and temporal neocortex is compromised preferentially. Further studies would be needed to investigate the relationship of rCBF change and cognitive impairment in patients with CHF.
