    This study focused on the relationship between attention and dementia screening test performance, using the adapted Wechsler's Digit Span test for elderly patients, the Cognitive Screening Test (CST) and the Amsterdam Dementia Screening Test (ADS6). Participants were dementia patients and psychiatric patients (n = 147). In both groups no floor-effect was found on the Digit Span test. Principal components analysis showed that CST and ADS6-scores had relatively high loadings on one factor, in contrast to digit span scores that loaded on a second factor. On average, psychiatric patients did hardly worse than normal controls. Attention deficits were more apparent in dementia patients. Considering a maximum of r = .41, these more or less subtle deficits were only moderately related to dementia screening test performance. It is concluded that the adapted Digit Span test is suitable for measuring attention deficits in elderly patients. However, Digit Span predicts performance on dementia screening test only to a modest degree.

    Objective The aims of the study were to (1) estimate the relative nurse effectiveness, or individual nurse value-added (NVA), to patients’ clinical condition change during hospitalization; (2) examine nurse characteristics contributing to NVA; and (3) estimate the contribution of value-added nursing care to patient outcomes. Data Sources/Study Setting Electronic data on 1,203 staff nurses matched with 7,318 adult medical–surgical patients discharged between July 1, 2011 and December 31, 2011 from an urban Magnet-designated, 854-bed teaching hospital. Study Design Retrospective observational longitudinal analysis using a covariate-adjustment value-added model with nurse fixed effects. Data Collection/Extraction Methods Data were extracted from the study hospital's electronic patient records and human resources databases. Principal Findings Nurse effects were jointly significant and explained 7.9 percent of variance in patient clinical condition change during hospitalization. NVA was positively associated with having a baccalaureate degree or higher (0.55, p = .04) and expertise level (0.66, p = .03). NVA contributed to patient outcomes of shorter length of stay and lower costs. Conclusions Nurses differ in their value-added to patient outcomes. The ability to measure individual nurse relative value-added opens the possibility for development of performance metrics, performance-based rankings, and merit-based salary schemes to improve patient outcomes and reduce costs.

  4. Boundary conditions for General Relativity on AdS3 and the KdV hierarchy

    It is shown that General Relativity with negative cosmological constant in three spacetime dimensions admits a new family of boundary conditions being labeled by a nonnegative integer k. Gravitational excitations are then described by "boundary gravitons" that fulfill the equations of the k-th element of the KdV hierarchy. In particular, k = 0 corresponds to the Brown-Henneaux boundary conditions so that excitations are described by chiral movers. In the case of k = 1, the boundary gravitons fulfill the KdV equation and the asymptotic symmetry algebra turns out to be infinite-dimensional, abelian and devoid of central extensions. The latter feature also holds for the remaining cases that describe the hierarchy ( k > 1). Our boundary conditions then provide a gravitational dual of two noninteracting left and right KdV movers, and hence, boundary gravitons possess anisotropic Lifshitz scaling with dynamical exponent z = 2 k + 1. Remarkably, despite spacetimes solving the field equations are locally AdS, they possess anisotropic scaling being induced by the choice of boundary conditions. As an application, the entropy of a rotating BTZ black hole is precisely recovered from a suitable generalization of the Cardy formula that is compatible with the anisotropic scaling of the chiral KdV movers at the boundary, in which the energy of AdS spacetime with our boundary conditions depends on z and plays the role of the central charge. The extension of our boundary conditions to the case of higher spin gravity and its link with different classes of integrable systems is also briefly addressed.

    Clinical study data management systems (CSDMSs) have many similarities to clinical patient record systems (CPRSs) in their focus on recording clinical parameters. Requirements for ad hoc query interfaces for both systems would therefore appear to be highly similar. However, a clinical study is concerned primarily with collective responses of groups of subjects to standardized therapeutic interventions for the same underlying clinical condition. The parameters that are recorded in CSDMSs tend to be more diverse than those required for patient management in non-research settings, because of the greater emphasis on questionnaires for which responses to each question are recorded separately. The differences between CSDMSs and CPRSs are reflected in the metadata that support the respective systems' operation, and need to be reflected in the query interfaces. The authors describe major revisions of their previously described CSDMS ad hoc query interface to meet CSDMS needs more fully, as well as its porting to a Web-based platform. PMID:12087118

    In Alzheimer disease, the gap between excellence of diagnostics and efficacy of therapy is wide. Despite sophisticated imaging and biochemical markers, the efficacy of available therapeutic options is limited. Here we examine the possibility that assessment of endogenous catecholamine levels in cerebrospinal fluid (CSF) may fuel new therapeutic strategies. In reviewing the available literature, we consider the effects of levodopa, monoamine oxidase inhibitors, and noradrenaline (NE) modulators, showing disparate results. We present a preliminary assessment of CSF concentrations of dopamine (DA) and NE, determined by HPLC, in a small dementia cohort of either Alzheimer’s disease (AD) or frontotemporal dementia patients, compared to control subjects. Our data reveal detectable levels of DA, NE in CSF, though we found no significant alterations in the dementia population as a whole. AD patients exhibit a small impairment of the DA axis and a larger increase of NE concentration, likely to represent a compensatory mechanism. While waiting for preventive strategies, a pragmatic approach to AD may re-evaluate catecholamine modulation, possibly stratified to dementia subtypes, as part of the therapeutic armamentarium.

    We have used MR DTI to identify relevant brain structures involved in visuospatial processing, in an attempt to link perceptual and attentional impairments to WM changes in Alzheimer's disease (AD) patients. Correlation of DTI measured parameters with results of several neuropsychological tests will be reported here. Several issues related to quantitation of DTI parameters in ROI analysis are addressed. In spite of only a small number of subjects were studied so far, we found not only that AD patients showed significant decrease of white matter (WM) integrity in corpus callosum (CC), most prominent at the posterior portion, but also found significant correlations between the DTI parameters and scores from several neuropsychological tests. Our preliminary results suggest that DTI help to improve the overall accuracy rate in distinguishing between early AD onset and age-related functional decline, and potentially may improve efficiency in differentiating between different types of dementia.

    Several studies have shown that reduced amyloid-beta 1-42 (Abeta(42)) and increased tau levels in cerebrospinal fluid (CSF) reflect increased Alzheimer's disease (AD) pathology in the brain. beta-site APP cleaving enzyme (BACE1) is thought to be the major beta-secretase involved in Abeta production in the brain, and therefore we investigated the relation between BACE1 activity and CSF markers Abeta(40), Abeta(42), total tau (t-tau), and tau phosphorylated at threonine 181 (p-tau) in CSF of control (n=12), mild cognitive impairment (n=18), and AD (n=17) subjects. Patients were classified according to their Abeta(42), t-tau, and p-tau CSF biomarker levels, with either an AD-like biomarker profile (two or three biomarkers abnormal: Abeta(42) < 495 pg/ml in combination with t-tau > 356 pg/ml, and/or p-tau > 54 pg/ml) or a normal biomarker profile (AD-like biomarker profile (66 +/- 6 years, 53% female, and Mini-Mental Status Examination (MMSE) score: 23 +/- 5) and 28 subjects with a normal biomarker profile (62 +/- 11 years, 43% female, and MMSE score: 27 +/- 4). Subjects with an AD-like biomarker profile had higher CSF BACE1 activity levels, compared to patients with a normal biomarker profile (20 pg/ml and 16 pg/ml respectively; p=0.01), when controlled for age and gender. In the whole sample, BACE1 activity correlated with CSF levels of Abeta(40), t-tau, and p-tau (r=0.38, r=0.63, and r=0.65; all p< 0.05), but not with Abeta(42). These data suggest that increased BACE1 activity in CSF relates to AD pathology in the brain.

    We consider curvature-squared corrections to Einstein-Hilbert gravity action in the form of a Gauss-Bonnet term in D>4 dimensions. In this theory, we study the thermodynamics of charged static black holes with anti-de Sitter (AdS) asymptotics, and whose electric field is described by nonlinear electrodynamics. These objects have received considerable attention in recent literature on gravity/gauge dualities. It is well-known that, within the framework of anti-de Sitter/conformal field theory (AdS/CFT) correspondence, there exists a nonvanishing Casimir contribution to the internal energy of the system, manifested as the vacuum energy for global AdS spacetime in odd dimensions. Because of this reason, we derive a quantum statistical relation directly from the Euclidean action and not from the integration of the first law of thermodynamics. To this end, we employ a background-independent regularization scheme which consists, in addition to the bulk action, of counterterms that depend on both extrinsic and intrinsic curvatures of the boundary (Kounterterm series). This procedure results in a consistent inclusion of the vacuum energy and chemical potential in the thermodynamic description for Einstein-Gauss-Bonnet AdS gravity regardless of the explicit form of the nonlinear electrodynamics Lagrangian.

    Numerous studies show that 17β-estradiol (E2) protects against Alzheimer's disease (AD) induced neurodegeneration. The E2-synthesizing enzyme aromatase is expressed in healthy hippocampi, but although the hippocampus is severely affected in AD, little is known about the expression of hippocampal aromatase in AD. To better understand the role of hippocampal aromatase in AD, we studied its expression in postmortem material from patients with AD and in a mouse model for AD (5xFAD mice). In human hippocampi, aromatase-immunoreactivity was observed in the vast majority of principal neurons and signal quantification revealed higher expression of aromatase protein in AD patients compared to age- and sex-matched controls. The tissue-specific first exons of aromatase I.f, PII, I.3, and I.6 were detected in hippocampi of controls and AD patients by RT-PCR. In contrast, 3-month-old, female 5xFAD mice showed lower expression of aromatase mRNA and protein (measured by qRT-PCR and semiquantitative immunohistochemistry) than WT controls; no such differences were observed in male mice. Our findings stress the importance of hippocampal aromatase expression in neurodegenerative diseases. PMID:27298742

    It is well established that oxidative stress plays a key role in the degenerative neuronal death and progression of Alzheimer's disease (AD), although it is not clear if it is the primary triggering event in the pathogenesis of this disorder. Mild cognitive impairment (MCI) is a clinical condition between normal aging and AD, characterized by a memory deficit without loss of general cognitive and functional abilities. We performed this study by a comet assay analysis to evaluate the level of primary and oxidative DNA damage in two groups of MCI and AD patients, compared to healthy controls. Data showed a significantly higher level of primary DNA damage in leukocytes of AD and also of MCI patients compared to control individuals (average: 2.09+/-0.79 and 2.47+/-1.01, respectively for AD and MCI, versus 1.04+/-0.31 in controls). Moreover, the amount of oxidised DNA bases (both purines and pyrimidines) was significatively higher in the two groups of patients (AD and MCI) compared to controls. Our results give a further indication that oxidative stress, at least at the DNA level, is an earlier event in the pathogenesis of AD.

    We find a simple relation between a free higher spin partition function on the thermal quotient of {{AdS}}d+1 and the partition function of the associated d-dimensional conformal higher spin field defined on the thermal quotient of {{AdS}}d. Starting with a conformal higher spin field defined in {{AdS}}d, one may also associate to with another conformal field in d-1 dimensions, thus iterating AdS/CFT. We observe that in the case of d=4, this iteration leads to a trivial 3d higher spin conformal theory with parity-even non-local action: it describes a zero total number of dynamical degrees of freedom and the corresponding partition function is equal to 1.

    A retrospective study. To summarize and describe the radiographic parameters of adult degenerative scoliosis (ADS) and explore the radiological parameters which are significantly different in sagittal balanced and imbalanced ADS patients. ADS is the most common type of adult spinal deformity. However, no comprehensive description of radiographic parameters in ADS patients has been made, and few studies have been performed to explore which radiological parameters are significantly different between sagittal balanced and imbalanced ADS patients. Medical records of ADS patients in our outpatient clinic from January 2012 to January 2014 were reviewed. Demographic data including age and sex, and radiographic data including the coronal Cobb angle, location of apical vertebra/disc, convexity of the curve, degree of apical vertebra rotation, curve segments, thoracic kyphosis (TK), lumbar lordosis (LL), thoracolumbar kyphosis (TL), sacral slope (SS), pelvic tilt (PT), pelvic incidence (PI), sagittal vertical axis (SVA), and PI minus LL (PI-LL) were reviewed to make comprehensive description of radiographic parameters of ADS. Furthermore, patients were divided into 2 groups according to whether the patients' sagittal plane was balanced: Group A (imbalanced, SVA > 5 cm) and Group B (balanced, SVA  ≤ 5 cm). Demographic and radiological parameters were compared between these 2 groups. A total of 99 patients were included in this study (Group A = 33 and Group B = 66; female = 83 and male = 16; sex ratio = 5:1). The median of age were 67 years (range: 41-92 years). The median of coronal Cobb angle and length of curve was 23 (range: 10-75°) and 5 segments (range: 3-7), respectively. The most common location of apical vertebra was at L2 to L3 (81%) and the median of degree of apical vertebra rotation was 2° (range: 1-3). Our study also showed significant correlations between coronal Cobb angle and curve segments (r = 0.23, P < 0.005) and degree of apical vertebra rotation (r

    Background Advantages and disadvantages of ad hoc percutaneous coronary intervention have been described. However little is known about the radiation exposure of that procedure as compared with the staged intervention. Objective To compare the radiation dose of the ad hoc percutaneous coronary intervention with that of the staged procedure Methods The dose-area product and total Kerma were measured, and the doses of the diagnostic and therapeutic procedures were added. In addition, total fluoroscopic time and number of acquisitions were evaluated. Results A total of 568 consecutive patients were treated with ad hoc percutaneous coronary intervention (n = 320) or staged percutaneous coronary intervention (n = 248). On admission, the ad hoc group had less hypertension (74.1% vs 81.9%; p = 0.035), dyslipidemia (57.8% vs. 67.7%; p = 0.02) and three-vessel disease (38.8% vs. 50.4%; p = 0.015). The ad hoc group was exposed to significantly lower radiation doses, even after baseline characteristic adjustment between both groups. The ad hoc group was exposed to a total dose-area product of 119.7 ± 70.7 Gycm2, while the staged group, to 139.2 ± 75.3 Gycm2 (p < 0.001). Conclusion Ad hoc percutaneous coronary intervention reduced radiation exposure as compared with diagnostic and therapeutic procedures performed at two separate times. PMID:26351982

    Amyloid imaging has been used to detect amyloid deposition in the brain. We performed Pittsburgh compound B (PiB)-positron emission tomography on 63 patients with dementia having cognitive decline or memory disturbance. In addition, we measured the patients' apolipoprotein E4 (apo E4) status and cerebrospinal fluid (CSF) levels of amyloid-β (Aβ)1-42, tau, and P-tau. Finally, the patients were diagnosed as having probable Alzheimer disease (AD) on the basis of their neuropsychological findings and because they met the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association criteria. Among the patients diagnosed with probable AD, 10 patients were PiB negative. The CSF levels of P-tau and tau in PiB-negative patients were significantly lower than those in the PiB-positive patients. In addition, the CSF levels of Aβ1-42 in the PiB-negative patients were significantly higher than those in the PiB-positive patients. None of the PiB-negative patients were apo E4 carriers. These results suggest that the PiB-negative patient group included not only AD patients but also non-AD-type dementia patients. However, our finding is based on a relatively small number of patients and therefore should be replicated in a larger cohort. In addition, it will be necessary to categorize these participants by longitudinal follow-up and postmortem pathological examinations.

    Accurate classification of Alzheimer's disease (AD) and its prodromal stage, mild cognitive impairment (MCI), plays a critical role in possibly preventing progression of memory impairment and improving quality of life for AD patients. Among many research tasks, it is of a particular interest to identify noninvasive imaging biomarkers for AD diagnosis. In this paper, we present a robust deep learning system to identify different progression stages of AD patients based on MRI and PET scans. We utilized the dropout technique to improve classical deep learning by preventing its weight coadaptation, which is a typical cause of overfitting in deep learning. In addition, we incorporated stability selection, an adaptive learning factor, and a multitask learning strategy into the deep learning framework. We applied the proposed method to the ADNI dataset, and conducted experiments for AD and MCI conversion diagnosis. Experimental results showed that the dropout technique is very effective in AD diagnosis, improving the classification accuracies by 5.9% on average as compared to the classical deep learning methods.

    The objective was to study the association between cerebrospinal fluid (CSF) levels of amyloid-β (Aβ)(1-42), t-tau, and p-tau and cognitive performance along the Alzheimer's disease (AD) continuum from healthy subjects to AD patients and, specifically, among patients in the pre-dementia stage of the disease. A total of 101 subjects were studied: 19 healthy controls (CTR), 17 subjects with subjective memory complaints (SMC), 47 with mild cognitive impairment (MCI), and 18 AD patients. Only memory performance significantly correlated with CSF levels of Aβ(1-42), t-tau, and p-tau along the AD continuum. Subgroup analyses revealed that in SMC patients Aβ(1-42) levels positively correlated with the total recall score of the Free and Cued Selective Reminding Test (FCRST) (r = 0.666; p < 0.005), Digit Span (r = 0.752; p < 0.005), and CERAD world list learning (r = 0.697; p < 0.005). In MCI patients, a significant inverse correlation was found between the word list recall score from the CERAD and t-tau (r = -0.483; p < 0.005) and p-tau levels (r = -0.495; p < 0.005), as well as between the total recall subtest score from the FCRST and both t-tau (r = -0.420; p < 0.005) and p-tau levels (r = -0.422; p < 0.005). No significant correlations were found between other aspects of cognition and CSF levels in CTR or AD patients. These results indicate that memory performance is related to Aβ(1-42) levels in SMC, while it is associated with tau in the prodromal stage of the disease. This suggests that in the continuum from healthy aging to AD, memory performance is first related with Aβ(1-42) levels and then with t-tau or p-tau, before becoming independent of biomarker levels in the dementia stage.

    Background: In vivo evaluation of cholinergic circuits of the human brain has recently been introduced using a transcranial magnetic stimulation (TMS) protocol based on coupling peripheral nerve stimulation with motor cortex TMS (short latency afferent inhibition, SAI). SAI is reduced in Alzheimer's disease (AD) and drugs enhancing cholinergic transmission increase SAI. Methods: We evaluated whether SAI testing, together with SAI test-retest, after a single dose of the acetylcholinesterase (AChE) inhibitor rivastigmine, might be useful in predicting the response after 1 year treatment with rivastigmine in 16 AD patients. Results: Fourteen AD patients had pathologically reduced SAI. SAI was increased after administration of a single oral dose of rivastigmine in AD patients with abnormal baseline SAI, but individual responses to rivastigmine varied widely, with SAI change ranging from an increase in inhibition of ∼50% of test size to no change. Baseline SAI and the increase in SAI after a single dose of rivastigmine were correlated with response to long term treatment. A normal SAI in baseline conditions, or an abnormal SAI in baseline conditions that was not greatly increased by a single oral dose of rivastigmine, were invariably associated with poor response to long term treatment, while an abnormal SAI in baseline conditions in conjunction with a large increase in SAI after a single dose of rivastigmine was associated with good response to long term treatment in most of the patients. Conclusions: Evaluation of SAI may be useful for identifying AD patients likely to respond to treatment with AChE inhibitors. PMID:16024879

    Platelets, like neurons, contain 120- to 130- and 110-kd amyloid precursor proteins (APPs). Their ratio is reduced in AD, further reductions correlating with reduced Mini-Mental Status Examination scores [r(11) = 0.69, p < 0.05]. As statins alter APP processing, platelet APPs were analyzed in patients with AD given anticholesterol drugs for 6 weeks. APP ratios increased [t(37) = -3.888, p = 0.0004], proportionally with reduced cholesterol [r(36) = -0.45, p = 0.005]. Longer trials may reveal slowed cognitive loss, validating this index.

    This study evaluates the individual, as well as relative and joint value of indices obtained from magnetic resonance imaging (MRI) patterns of brain atrophy (quantified by the SPARE-AD index), cerebrospinal fluid (CSF) biomarkers, APOE genotype, and cognitive performance (ADAS-Cog) in progression from mild cognitive impairment (MCI) to Alzheimer's disease (AD) within a variable follow-up period up to 6 years, using data from the Alzheimer's Disease Neuroimaging Initiative-1 (ADNI-1). SPARE-AD was first established as a highly sensitive and specific MRI-marker of AD vs. cognitively normal (CN) subjects (AUC = 0.98). Baseline predictive values of all aforementioned indices were then compared using survival analysis on 381 MCI subjects. SPARE-AD and ADAS-Cog were found to have similar predictive value, and their combination was significantly better than their individual performance. APOE genotype did not significantly improve prediction, although the combination of SPARE-AD, ADAS-Cog and APOE ε4 provided the highest hazard ratio estimates of 17.8 (last vs. first quartile). In a subset of 192 MCI patients who also had CSF biomarkers, the addition of Aβ1-42, t-tau, and p-tau181p to the previous model did not improve predictive value significantly over SPARE-AD and ADAS-Cog combined. Importantly, in amyloid-negative patients with MCI, SPARE-AD had high predictive power of clinical progression. Our findings suggest that SPARE-AD and ADAS-Cog in combination offer the highest predictive power of conversion from MCI to AD, which is improved, albeit not significantly, by APOE genotype. The finding that SPARE-AD in amyloid-negative MCI patients was predictive of clinical progression is not expected under the amyloid hypothesis and merits further investigation.

    Obesity is associated with lower brain volumes in cognitively normal elderly subjects, but no study has yet investigated the effects of obesity on brain structure in patients with mild cognitive impairment (MCI) or Alzheimer’s disease (AD). To determine if higher body mass index (BMI) is associated with brain volume deficits in cognitively impaired elderly subjects, we analyzed brain magnetic resonance imaging (MRI) scans of 700 MCI or AD patients from two different cohorts: the Alzheimer’s Disease Neuroimaging Initiative (ADNI) and the Cardiovascular Health Study-Cognition Study (CHS-CS). Tensor-based morphometry (TBM) was used to create 3-dimensional maps of regional tissue excess or deficits in subjects with MCI (ADNI, N=399; CHS, N=77) and AD (ADNI, N=188; CHS, N=36). In both AD and MCI groups, higher BMI was associated with brain volume deficits in frontal, temporal, parietal, and occipital lobes; the atrophic pattern was consistent in both ADNI and CHS populations. Cardiovascular risk factors, especially obesity, should be considered as influencing brain structure in those already afflicted by cognitive impairment and dementia. PMID:20570405

    A 14-year-old who had suffered from a beta-hemolytic streptococcus infection presented with serious temporomandibular disorders, including a reabsorption of the condyle head on the right side, and reabsorption in the cavern of the left side. Her masticatory muscles were electronically deprogramed, achieving a mandibular position supported by a relaxed musculature. The patient's signs and symptoms subsequently disappeared. Study of the magnetic resonance image a year later clearly showed a regeneration ad integrum of the condyle head and a spontaneous reinsertion of the articular disk. The results suggest the need for use of electronic elements in order to treat patients with temporomandibular disorders effectively. PMID:10650410

    Objectives: To evaluate relatives' attitudes towards informing patients with Alzheimer's disease (AD) about their diagnosis. Setting: A university hospital in Italy. Methods: The closest relatives of each of 71 subjects diagnosed for the first time as having AD were interviewed, using a semistructured questionnaire. Spontaneous requests by relatives not to communicate issues concerning the diagnosis were also recorded. Results: Forty three (60.6%) relatives spontaneously requested that patients not be fully informed. After being interviewed, nobody thought that the patient should be given all the information. Justifications were related to the fear of the onset or worsening of depressive symptoms in the patient. Conclusions: In Italy relatives' opposition to informing AD patients appears to be common. Knowledge of the relatives' attitudes may be useful for clinicians but disclosure of diagnosis should be based on the clinical evaluation of the patient and on a prudent evaluation of the relationship between the patient and her/his relative caregiver.

    Objective Relatives of ethnic minority patients often play an important role in the care process during hospitalisation. Our objective was to analyse the role of these relatives in relation to the safety of patients during hospital care. Setting Four large urban hospitals with an ethnic diverse patient population. Participants On hospital admission of ethnic minority patients, 20 cases were purposively sampled in which relatives were observed to play a role in the care process. Outcome measures We used documents (patient records) and added eight cases with qualitative interviews with healthcare providers, patients and/or their relatives to investigate the relation between the role of relatives and patient safety. An inductive approach followed by selective coding was used to analyse the data. Results Besides giving social support, family members took on themselves the role of the interpreter, the role of substitutes of the patient and the role of care provider. The taking over of these roles can have positive and negative effects on patient safety. Conclusions When family members take over various roles during hospitalisation of a relative, this can lead to a safety risk and a safety protection for the patient involved. Although healthcare providers should not hand over their responsibilities to the relatives of patients, optimising collaboration with relatives who are willing to take part in the care process may improve patient safety.

    We present area (or entropy) functional relation for multi-horizons five dimensional (5D) Einstein-Maxwell-Gauss-Bonnet-AdS black hole. It has been observed by exact and explicit calculation that some complicated function of two or three horizons area is mass-independent whereas the entropy product relation is not mass-independent. We also study the local thermodynamic stability of this black hole. The phase transition occurs at certain condition. Smarr mass formula and first law of thermodynamics have been derived. This mass-independent relation suggests they could turn out to be an universal quantity and further helps us to understanding the nature of black hole entropy (both interior and exterior) at the microscopic level. In the "Appendix", we have derived the thermodynamic products for 5D Einstein-Maxwell-Gauss-Bonnet black hole with vanishing cosmological constant.

    Objective: To examine whether engagement in physical activity might favorably alter the age-dependent evolution of Alzheimer disease (AD)-related brain and cognitive changes in a cohort of at-risk, late-middle-aged adults. Methods: Three hundred seventeen enrollees in the Wisconsin Registry for Alzheimer's Prevention underwent T1 MRI; a subset also underwent 11C-Pittsburgh compound B–PET (n = 186) and 18F-fluorodeoxyglucose–PET (n = 152) imaging. Participants' responses on a self-report measure of current physical activity were used to classify them as either physically active or physically inactive based on American Heart Association guidelines. They also completed a comprehensive neuropsychological battery. Covariate-adjusted regression analyses were used to test whether the adverse effect of age on imaging and cognitive biomarkers was modified by physical activity. Results: There were significant age × physical activity interactions for β-amyloid burden (p = 0.014), glucose metabolism (p = 0.015), and hippocampal volume (p = 0.025) such that, with advancing age, physically active individuals exhibited a lesser degree of biomarker alterations compared with the physically inactive. Similar age × physical activity interactions were also observed on cognitive domains of Immediate Memory (p = 0.042) and Visuospatial Ability (p = 0.016). In addition, the physically active group had higher scores on Speed and Flexibility (p = 0.002) compared with the inactive group. Conclusions: In a middle-aged, at-risk cohort, a physically active lifestyle is associated with an attenuation of the deleterious influence of age on key biomarkers of AD pathophysiology. However, because our observational, cross-sectional design cannot establish causality, randomized controlled trials/longitudinal studies will be necessary for determining whether midlife participation in structured physical exercise forestalls the development of AD and related disorders in later life.

    Lifelong cognitive stimulation is associated with a lower risk of Alzheimer's disease (AD), but causality is difficult to prove. We therefore sought to investigate the preventative potential of environmental enrichment (EE) using mice expressing both human mutant presenilin-1 and the amyloid precursor protein (PS1/PDAPP). At weaning, mice were placed into either an enriched or standard housing environment. Behavioral testing at 4.5-6 months showed that environmentally enriched PS1/PDAPP mice outperformed mice in standard housing, and were behaviorally indistinguishable from non-transgenic mice across multiple cognitive domains. PS1/PDAPP mice exposed to both environmental enrichment and behavioral testing, but not to EE alone, showed 50% less brain beta-amyloid without improved dendritic morphology. Microarray analysis revealed large enrichment-induced changes in hippocampal expression of genes/proteins related to Abeta sequestration and synaptic plasticity. These results indicate that EE protects against cognitive impairment in AD transgenic mice through a dual mechanism, including both amyloid dependent and independent mechanisms.

    Hyperphosphatemia is an important determinant of morbidity and mortality in patients with chronic kidney disease (CKD). Patients with CKD are advised to consume a low phosphate diet and are often prescribed phosphate-lowering drug therapy. However, commercially processed food and drinks often contain phosphate compounds, but the phosphate level is not usually provided in the ingredient list, which makes it difficult for CKD patients to choose a correct diet. We conducted a survey of the awareness of food/beverages containing artificially added phosphate among CKD patients undergoing hemodialysis. The subjects were 153 patients (77 males and 76 females; average age 56±11 years) who were randomly selected from the Dialysis Center of Hirosaki City, Japan. The subjects were provided with a list of questions. The survey results showed that 93% of the subjects were aware of the presence of high sugar content in soda, whereas only 25% were aware of the presence of phosphate (phosphoric acid) in such drinks. Despite 78% of the subjects being aware of the detrimental effects of consumption of a high phosphate diet, 43% drank at least 1 to 5 cans of soda per week and about 17% consumed "fast food" once each week. We also assessed the immediate effects of high-phosphate containing carbonated soda consumption by determining urinary calcium, phosphate, protein and sugar contents in overnight fasted healthy volunteers (n = 55; average age 20.7±0.3 years old, 20 males and 35 females). Significantly higher urinary calcium (adjusted using urinary creatinine) excretion was found 2 h after consuming 350 ml of carbonated soda compared to the fasting baseline level (0.15±0.01 vs. 0.09±0.01, p = 0.001). Our survey results suggest that CKD patients undergoing hemodialysis are not adequately aware of the hidden source of phosphate in their diet, and emphasize the need for educational initiatives to raise awareness of this issue among CKD patients.

    A retrospective clinical evaluation of patients consecutively treated from multiple centers was performed. The treatment of these patients utilized the bone-added osteotome sinus floor elevation (BAOSFE) procedure with immediate implant fixation. The BAOSFE method employs a specific set of osteotome instruments to tent the sinus membrane with bone graft material placed through the osteotomy site. A total of 174 implants was placed in 101 patients. Implants were of both screw and cylinder shapes with machined, titanium plasma-sprayed, and hydroxyapatite surfaces from various manufacturers. The 9 participating clinicians used autografts, allografts, and xenografts alone or in various combinations, and the type of graft was selected by the individual clinicians. The choice of graft material did not appear to influence survival rates. Loading periods varied from 6 to 66 months. The survival rate was 96% or higher when pretreatment bone height was 5 mm or more and dropped to 85.7% when pretreatment bone height was 4 mm or less. The most important factor influencing implant survival with the BAOSFE was the preexisting bone height between the sinus floor and crest. This short-term retrospective investigation suggests that the BAOSFE can be a successful procedure with a wide variety of implant types and grafting procedures. PMID:10612923

    Alzheimer's disease (AD) is a multifactorial neurological condition associated with a genetic profile that is still not completely understood. In this study, using a whole gene microarray approach, we investigated age-dependent gene expression profile changes occurring in the hippocampus of young and old transgenic AD (3xTg-AD) and wild-type (WT) mice. The aim of the study was to assess similarities between aging- and AD-related modifications of gene expression and investigate possible interactions between the two processes. Global gene expression profiles of hippocampal tissue obtained from 3xTg-AD and WT mice at 3 and 12 months of age (m.o.a.) were analyzed by hierarchical clustering. Interaction among transcripts was then studied with the Ingenuity Pathway Analysis (IPA) software, a tool that discloses functional networks and/or pathways associated with sets of specific genes of interest. Cluster analysis revealed the selective presence of hundreds of upregulated and downregulated transcripts. Functional analysis showed transcript involvement mainly in neuronal death and autophagy, mitochondrial functioning, intracellular calcium homeostasis, inflammatory response, dendritic spine formation, modulation of synaptic functioning, and cognitive decline. Thus, overexpression of AD-related genes (such as mutant APP, PS1, and hyperphosphorylated tau, the three genes that characterize our model) appears to favor modifications of additional genes that are involved in AD development and progression. The study also showed overlapping changes in 3xTg-AD at 3 m.o.a. and WT mice at 12 m.o.a., thereby suggesting altered expression of aging-related genes that occurs earlier in 3xTg-AD mice.

    Although lightning strike is an important cause of sudden death in livestock on pasture and among the main reasons why insurance companies consult an expert veterinarian, scientific information on this subject is limited. The aim of the present study was to provide objective information on the circumstantial evidence and pathological findings in lightning related fatalities (LRF), based on a retrospective analysis of 410 declarations, examined by a single expert veterinarian in Flanders, Belgium, from 1998 to 2012. Predictive logistic models for compatibility with LRF were constructed based on anamnestic, environmental and pathological factors. In addition, the added value of lightning location data (LLD) was evaluated. Pathognomonic singe lesions were present in 84/194 (43%) confirmed reports. Factors which remained significantly associated with LRF in the multivariable model were age, presence of a tree or open water in the near surroundings, tympany and presence of feed in the oral cavity at the time of investigation. This basic model had a sensitivity (Se) of 53.8% and a specificity (Sp) of 88.2%. Relying only on LLD to confirm LRF in livestock resulted in a high Se (91.3%), but a low Sp (41.2%), leading to a high probability that a negative case would be wrongly accepted as an LRF. The best results were obtained when combining the model based on the veterinary expert investigation (circumstantial evidence and pathological findings), together with the detection of cloud-to-ground (CG) lightning at the time and location of death (Se 89.1%; Sp 66.7%).

    Cerebrospinal fluid (CSF) concentrations of YKL-40 that serve as biomarker of neuroinflammation are known to be altered along the clinico-biological continuum of Alzheimer's disease (AD). The specific structural cerebral correlates of CSF YKL-40 were evaluated across the early stages of AD from normal to preclinical to mild dementia. Nonlinear gray matter (GM) volume associations with CSF YKL-40 levels were assessed in a total of 116 subjects, including normal controls and those with preclinical AD as defined by CSF Aβ < 500 pg/mL, mild cognitive impairment (MCI) due to AD, or mild AD dementia. Age-corrected YKL-40 levels were increased in MCIs versus the rest of groups and showed an inverse u-shaped association with p-tau values. A similar nonlinear relationship was found between GM volume and YKL-40 in inferior and lateral temporal regions spreading to the supramarginal gyrus, insula, inferior frontal cortex, and cerebellum in MCI and AD. These findings for YKL-40 remained unchanged after adjusting for p-tau, which was found to be associated with GM volumes in distinct anatomic areas. CSF YKL-40, a biomarker of glial inflammation, is associated with a cerebral structural signature distinct from that related to p-tau neurodegeneration at the earliest stages of cognitive decline due to AD.

    2012-01-01

    Background Anticoagulation, the use of sequential compression devices on lower extremities peri-operatively, and early ambulation are thought to reduce venous thromboembolism (VTE) postoperatively and are recommended to reduce VTE risk. However, the evidence upon which this recommendation is based is not particularly strong. We demonstrate that even a large, multi-center cohort with carefully collected prospective data is inadequate to provide sufficient evidence to support, or refute, this recommendation. Methods The Longitudinal Assessment of Bariatric Surgery (LABS) participants from 10 centers in the United States who underwent their first bariatric surgery between March, 2005 and December, 2007 comprise the study group. We examined the ability to address the question of whether anti-coagulation therapy, in addition to sequential compression, reduces the 30 day incidence of VTE or death sufficiently to recommend the use of prophylactic anticoagulation, a therapy that is not without risk. Results Of 4416 patients, 396 (9.0%) received sequential compression alone, while the others also received anticoagulation therapy. The incidence of VTE within 30 days of surgery was small (0.25% among those receiving sequential compression alone, 0.47% when anticoagulation therapy was added), and the 30 days incidence of death was also small (0.25% vs. 0.34%, p = 0.76, for sequential compression alone vs. sequential compression plus anticoagulation therapy). Estimates of the number of cases required to address the question of whether there is a difference in outcome related to VTE chemoprophylaxis, or whether the outcome rates are equivalent, range from 13,680 to at least 35,760 patients, depending upon whether superiority or equivalence is being analyzed. Conclusion Sufficient evidence from a clinical trial study to determine whether prophylactic anticoagulation added to compression devices further prevents VTEs is not available and such a trial is likely to be impractical

    The pace of research on the causes and consequences of obesity has increased dramatically since the late 1990s. However, a great chasm exists between the high-quality measurements of fatness used in the medical literature and the mostly self-reported height and weight data found in social science surveys. This article discusses the scientific value of including more accurate measures of fatness in the Panel Study of Income Dynamics (PSID). It describes why fatness and obesity are of interest to PSID users, the concepts they measure, the strengths and weaknesses of alternative biomeasures for these concepts, the value added of including each in the PSID, and their synergies with the PSID structure. Although no single measure of fatness is ideal for every situation, given scarce PSID resources we recommend adding waist circumference, percentage of body fat, total body fat, and fat free mass through a method such as bioelectrical impedance analysis, as well as determining genetic predisposition to obesity.

    The pathway of anaerobic toluene degradation is initiated by a remarkable radical-type enantiospecific addition of the chemically inert methyl group to the double bond of a fumarate cosubstrate to yield (R)-benzylsuccinate as the first intermediate, as catalyzed by the glycyl radical enzyme benzylsuccinate synthase. In recent years, it has become clear that benzylsuccinate synthase is the prototype enzyme of a much larger family of fumarate-adding enzymes, which play important roles in the anaerobic metabolism of further aromatic and even aliphatic hydrocarbons. We present an overview on the biochemical properties of benzylsuccinate synthase, as well as its recently solved structure, and present the results of an initial structure-based modeling study on the reaction mechanism. Moreover, we compare the structure of benzylsuccinate synthase with those predicted for different clades of fumarate-adding enzymes, in particular the paralogous enzymes converting p-cresol, 2-methylnaphthalene or n-alkanes.

Among patients with ≥2 RAI prescriptions (RAIp), persistence during the 12-month follow-up was assessed. Multivariate logistic regression analyses identified factors affecting RAI use and persistence. Of 3734 patients adding RAI to their OAD regimen, 2334 (62.5%) had a RAIp during follow-up. Factors associated with RAIp included using ≤2 OADs; cognitive impairment, basal insulin use during follow-up; and higher RAI out-of-pocket costs ($36 to <$56 versus $0 to $6.30). Patients were less likely to persist with RAI when on ≤2 OADs versus ≥3 OADs and when having higher RAI out-of-pocket costs ($36 to <$56 versus $0 to $6.30) and more likely to persist when they had cognitive impairment and basal insulin use during follow-up. Real-world persistence of RAI in insulin-naïve elderly patients with type 2 diabetes was very poor when RAI was added to an OAD regimen. PMID:27761472

  9. Cross-talk between Aβ and endothelial SSAO/VAP-1 accelerates vascular damage and Aβ aggregation related to CAA-AD.

    An association between semicarbazide-sensitive amine oxidase (SSAO) and cerebral amyloid angiopathy (CAA) related to Alzheimer's disease (AD) has been largely postulated. Increased SSAO activity and expression have been detected in cerebrovascular tissue and plasma of AD patients, colocalizing with cerebrovascular amyloid-beta (Aβ) deposits. As an enzyme, SSAO metabolizes primary amines generating hydrogen peroxide, ammonia, and aldehydes. The ability of these products to generate oxidative stress, to enhance the advanced glycation end-product generation, to promote the Aβ aggregation in vitro, and to induce apoptosis supports its role in CAA-related vascular pathology. However, whether the SSAO increase constitutes a cause or it is a consequence of the pathologic process has not been elucidated so far. To set up the nature of this relationship, vascular cell models expressing SSAO were treated with different Aβ forms, simulating the CAA conditions in vitro. It was found that the presence of the vasculotropic Dutch-mutated Aβ1-40 increases (Aβ1-40 D) the SSAO-dependent toxicity, which is accompanied by an increase of SSAO protein availability in endothelial cell membranes. In addition, SSAO enhances Aβ1-40 D and Aβ1-42 deposition on vascular cells by both activity-dependent and -independent mechanisms. Thus, we provide evidences indicating that Aβ itself could be one of the factors inducing SSAO increase in AD, enhancing its toxic effect, and inducing the vascular dysfunction and, in turn, that SSAO stimulates Aβ deposition on the vascular walls, thereby contributing to the CAA-AD progression. Therefore, molecules inhibiting SSAO could provide an alternative treatment for preventing/delaying the progress of CAA-AD-associated vasculopathy.

  10. Quality specifications: self pleasure for clinical laboratories or added value for patient management?

    PubMed

    Plebani, Mario

    2007-01-01

    Analytical quality specifications play a key role in assuring and continuously improving high-quality laboratory services. However, I believe, that there are two "missing links" in the effective management of quality specifications in the delivery of laboratory services. The first is the evidence that pre-analytical variation and related problems are not taken into great consideration by laboratory professionals. The second missing link is the communication of quality specifications to clinicians and other possible stakeholders. If quality specifications represent "the level of performance required to facilitate clinical decision-making", they cannot be used only for internal quality management procedures but must be communicated to facilitate clinical reasoning, decision-making and patient management. A consensus should be achieved in the scientific community on these issues to assure better utilization of laboratory data and, ultimately, improved clinical outcomes.

    Database queries involving imprecise or fuzzy predicates are currently an evolving area of academic and industrial research. Such queries place severe stress on the indexing and I/O subsystems of conventional database environments since they involve the search of large numbers of records. The Datacycle architecture and research prototype is a database environment that uses filtering technology to perform an efficient, exhaustive search of an entire database. It has recently been modified to include fuzzy predicates in its query processing. The approach obviates the need for complex index structures, provides unlimited query throughput, permits the use of ad-hoc fuzzy membership functions, and provides a deterministic response time largely independent of query complexity and load. This paper describes the Datacycle prototype implementation of fuzzy queries and some recent performance results.

    Purpose: To examine the value of androgen deprivation (AD) in the curative treatment of low- and intermediate-risk prostate cancer treated with the three major modalities: radical retropubic prostatectomy (RRP), external beam radiotherapy (EBRT), and permanent prostate implantation (PI). Methods and materials: During 1996-2001, 1668 patients with low- and intermediate-risk prostate cancer were treated at The Cleveland Clinic Foundation. Only patients with a minimum of 2 years of prostate-specific antigen follow-up were included in the analysis, and biochemical relapse-free survival (bRFS) was used as the endpoint. Patients were grouped according to treatment modality and stratified according to the use of AD. Results: The overall 5-year bRFS rate was 87.8%. The 5-year bRFS rate for low-risk patients was 89% and for intermediate-risk patients was 79%. For low-risk patients, the 5-year bRFS rates by treatment modality (without AD vs. with AD, respectively) were PI: 90% vs. 93%; EBRT: 90% vs. 93%; and RRP: 89% vs. 84%. For intermediate-risk patients, the 5-year bRFS rates by treatment modality (without AD vs. with AD, respectively) were PI: 88% vs. 82%; EBRT: 81% vs. 84%; and RRP: 75% vs. 72%. None of the comparisons within risk groups or among modalities supports an increased efficacy with the use of AD. Conclusion: Five-year bRFS rates in low-risk and intermediate-risk patients are not improved by the use of AD.

    Abstract Posterior cortical atrophy (PCA) is a neurodegenerative syndrome characterized by predominant visual deficits and parieto‐occipital atrophy, and is typically associated with Alzheimer's disease (AD) pathology. In AD, assessment of hippocampal atrophy is widely used in diagnosis, research, and clinical trials; its utility in PCA remains unclear. Given the posterior emphasis of PCA, we hypothesized that hippocampal shape measures may give additional group differentiation information compared with whole‐hippocampal volume assessments. We investigated hippocampal volume and shape in subjects with PCA (n = 47), typical AD (n = 29), and controls (n = 48). Hippocampi were outlined on MRI scans and their 3D meshes were generated. We compared hippocampal volume and shape between disease groups. Mean adjusted hippocampal volumes were ∼8% smaller in PCA subjects (P < 0.001) and ∼22% smaller in tAD subject (P < 0.001) compared with controls. Significant inward deformations in the superior hippocampal tail were observed in PCA compared with controls even after adjustment for hippocampal volume. Inward deformations in large areas of the hippocampus were seen in tAD subjects compared with controls and PCA subjects, but only localized shape differences remained after adjusting for hippocampal volume. The shape differences observed, even allowing for volume differences, suggest that PCA and tAD are each associated with different patterns of hippocampal tissue loss that may contribute to the differential range and extent of episodic memory dysfunction in the two groups.

    Amyloid is a generic term for insoluble, often intensely hydrophobic, fibrous protein aggregates that arise from inappropriately folded versions of naturally-occurring polypeptides. The abnormal generation and accumulation of amyloid, often referred to as amyloidogenesis, has been associated with the immune and pro-inflammatory pathology of several progressive age-related diseases of the human central nervous system (CNS) including Alzheimer's disease (AD) and age-related macular degeneration (AMD). This 'research perspective' paper reviews some of the research history, biophysics, molecular-genetics and environmental factors concerning the contribution of amyloid beta (Aβ) peptides, derived from beta-amyloid precursor protein (βAPP), to AD and AMD that suggests an extensive similarity in immune and inflammatory degenerative mechanisms between these two CNS diseases.

    AIM: To investigate the role of pegylated-interferon (IFN) α-2b in the management of patients with lamivudine-resistant chronic hepatitis B. METHODS: Twenty consecutive anti-HBe positive patients were treated with pegylated IFN α-2b (100 μg sc once weekly) for 12 mo. There was no interruption in lamivudine therapy. Hematology, liver biochemistry, serum HBV DNA levels were detected by PCR, and vital signs were also assessed. Liver histology was assessed in some patients at entry and at wk 52 for comparison. RESULTS: Nine patients (45%) had a partial virological end-treatment response; seven patients (35%) showed complete virological end-treatment response. Eight patients (40%) showed biochemical end-treatment response. There was a trend for higher virological response rates in patients who had previously responded to IFN and relapsed compared to IFN non-responders (four out of seven patients vs none out of six patients, respectively; P = 0.1). Patients without virological end-treatment response showed significant worsening of fibrosis [median score 2 (range, 1 to 3) vs median score 3 (range, 1 to 4)], in the first and second biopsy respectively (P = 0.014), whereas necroinflammatory activity was not significantly affected. Patients with complete or partial virological end-treatment response did not show any significant changes in histological findings, possibly due to the small number of patients with paired biopsies (n = 5). Nevertheless, after 12 mo of follow-up, only one patient (5%) showed sustained virological response and only 2 patients (10%) showed sustained biochemical response. Two patients (10%) discontinued pegylated IFN both after 6 mo of treatment due to flu-like symptoms. CONCLUSION: Pegylated IFNα-2b, when added to ongoing lamivudine therapy in patients with lamivudine-resistant chronic hepatitis B, induces sustained responses only in a small minority of cases.

    Over 10 years ago a project was initiated by the U.S. Army AVSCOM to update the military helicopter flying qualities specification MIL-8501-A. While not yet complete, the project reached a major milestone in 1989 with the publication of an Airworthiness Design Standard, ADS-33C. The 8501 update project initially set out to identify critical gaps in the requisite data base and then proceeded to fill them using a variety of directed research studies. The magnitude of the task required that it become an international effort: appropriate research studies were conducted in Germany, the UK and Canada as well as in the USA. Canadian participation was supported by the Department of National Defence (DND) through the Chief of Research and Development. Both ground based and in-flight simulation were used to study the defined areas and the Canadian Bell 205-A1 variable stability helicopter was used extensively as one of the primary research tools available for this effort. This paper reviews the involvement of the Flight Research Laboratory of the National Research Council of Canada in the update project, it describes the various experiments conducted on the Airborne Simulator, it notes significant results obtained and describes ongoing research associated with the project.

  17. Ondansetron and simvastatin added to treatment as usual in patients with schizophrenia: study protocol for a randomized controlled trial

    PubMed Central

    2013-01-01

    Background Negative symptoms and cognitive deficits are two partially-related features of schizophrenia which have a major negative impact on social function and objective quality of life. Standard drug treatments have little impact on either. There is some evidence that anti-inflammatory treatment may have beneficial effects in schizophrenia and major depression. Statins are cholesterol-lowering agents that have been found to be anti-inflammatory agents and are also known to decrease C-reactive protein (CRP). Ondansetron is a serotonin (5-HT3) receptor antagonist widely used to prevent nausea and vomiting in patients receiving chemotherapy for cancer. Small studies have suggested that ondansetron is effective as an adjunct drug in improving the symptoms of schizophrenia. Methods/design This is a two center, six-month, double-blind placebo controlled, factorial design study of ondansetron and/or simvastatin added to treatment as usual for patients suffering from schizophrenia, schizoaffective disorder, psychosis not otherwise specified or schizophreniform disorder. This will be a 2 × 2 design, with 54 patients in each cell, giving a total of 216 patients over three years. There will be a screening, a randomization and seven follow-up visits. Full clinical and neurocognitive assessments will be carried out at baseline (randomization), 14 weeks and at 26 weeks, while the positive and negative syndrome scale (PANSS), pill count and side effects checklist will be carried out at every visit. Simvastatin will be started at 20 mg once daily (OD), this will be increased to 40 mg after four weeks. Ondansetron will be administered in an 8 mg dose. Discussion Anti-inflammatory treatments have been shown to have some beneficial effects in schizophrenia. Both simvastatin and ondansetron provide some evidence of a reduction in symptoms compared to treatment as usual. The aim of this study is to establish the degree of improvement in negative symptoms with the addition of

    Hypercholesterolemic patients (n = 1,547) at high atherosclerotic cardiovascular disease risk with low-density lipoprotein cholesterol (LDL-C) levels ≥100 and ≤160 mg/dl while treated with atorvastatin 10 mg/day entered a multicenter, randomized, double-blind, active-controlled, clinical trial using two 6-week study periods. Period I compared the efficacy/safety of (1) adding ezetimibe 10 mg (ezetimibe) to stable atorvastatin 10 mg, (2) doubling atorvastatin to 20 mg, or (3) switching to rosuvastatin 10 mg. Subjects in the latter 2 groups who persisted with elevated LDL-C levels (≥100 and ≤160 mg/dl) after period I, entered period II; subjects on atorvastatin 20 mg had ezetimibe added to their atorvastatin 20 mg, or uptitrated their atorvastatin to 40 mg; subjects on rosuvastatin 10 mg switched to atorvastatin 20 mg plus ezetimibe or uptitrated their rosuvastatin to 20 mg. Some subjects on atorvastatin 10 mg plus ezetimibe continued the same treatment into period II. At the end of period I, ezetimibe plus atorvastatin 10 mg reduced LDL-C significantly more than atorvastatin 20 mg or rosuvastatin 10 mg (22.2% vs 9.5% or 13.0%, respectively, p <0.001). At the end of period II, ezetimibe plus atorvastatin 20 mg reduced LDL-C significantly more than atorvastatin 40 mg (17.4% vs 6.9%, p <0.001); switching from rosuvastatin 10 mg to ezetimibe plus atorvastatin 20 mg reduced LDL-C significantly more than uptitrating to rosuvastatin 20 mg (17.1% vs 7.5%, p <0.001). Relative to comparative treatments, ezetimibe added to atorvastatin 10 mg (period I) or atorvastatin 20 mg (period II) produced significantly greater percent attainment of LDL-C targets <100 or <70 mg/dl, and significantly greater percent reductions in total cholesterol, non-high-density lipoprotein cholesterol, most lipid and lipoprotein ratios, and apolipoprotein B (except ezetimibe plus atorvastatin 20 vs atorvastatin 40 mg).

    The quality of health care depends, among others, on the quality of a physician's domain knowledge. Since it is impossible to keep up with all new findings and developments, physicians usually have gaps in their domain knowledge. To handle exceptional cases, access to the full range of medical literature is required. The specific literature needed for appropriate treatment of the patient is described by a physician's information need. Physicians are often unaware of their information needs. To support them, this paperThis research is part of the MIA project (Medical Information Agent), which is funded by NWO (grant number 634.000.021). aims at presenting a first step towards automatically formulating patient-related information needs. We start investigating how we can model a physician's information needs in general. Then we propose an approach to instantiate the model into a representation of a physician's information needs using the patient data as stored in a medical record. Our experiments show that this approach is feasible. Since the number of formulated patient-related information needs is rather high, we propose the use of filters. Future research will focus on the combination of personalization and filtering. It is expected that the resultant set of information needs will have a manageable size and contributes to the quality of health care.

    Context Hepatitis C virus (HCV) infection is a major cause of liver-morbidity and mortality among patients with thalassemia. Peginterferon plus ribavirin is currently the recommended therapy for hepatitis C infection in patients do not have thalassemia, but using ribavirin in patients with thalassemia is restricted due to its hemolytic effect. To evaluate the efficacy and safety of adding ribavirin to peginterferon or interferon, authors performed a systematic review on the available literatures. Evidence Acquisition Trials were identified through electronic database, manual searches of journals and bibliographies and approaching authors of trials. Randomized trials that enrolled patients with a diagnosis of thalassemia and chronic hepatitis C infection treated with interferon or peginterferon with or without ribavirin were included. Two investigators independently evaluated the trials for inclusion criteria, risk of bias and data extraction. The primary outcomes were sustained virological response (SVR), liver-related morbidity, mortality and adverse events. The odds ratios from each trial were calculated individually and in the subgroup analysis of trials. Data were analyzed with fixed-effect model. Results Three randomized clinical trials with 92 patients were included. All three trials had unclear risk of bias. Compared with peginterferon monotherapy, adding ribavirin to peginterferon had significant beneficial effect on sustained virological response (OR = 3.44, 95% CI: 1.18 - 10.06). There was no significant difference between combination therapy and monotherapy in the end of treatment achievement response. Other than about 30% increase in blood transfusion due to anemia that returned to normal level 2 - 3 months after treatment, there was no significant increase in side effects followed by adding ribavirin to pegylated interferon (Peg-IFN). Data were insufficient to determine the impact of genotype, viral load and age on the response to treatment

    This paper proposes a model of adding relations in multi-levels to a formal organization structure with two subordinates such that the communication of information between every member in the organization becomes the most efficient. When edges between every pair of nodes with the same depth in L (L = 1, 2, …, H) levels are added to a complete binary tree of height H, an optimal set of depths {N1, N2, …, NL} (H⩾N1>N2> …>NL⩾1) is obtained by maximizing the total shortening path length which is the sum of shortening lengths of shortest paths between every pair of all nodes in the complete binary tree. It is shown that {N1, N2, …, NL}* = {H, H-1, …, H-L+1}.

    NETMARK is a flexible, high-throughput software system for managing, storing, and rapid searching of unstructured and semi-structured documents. NETMARK transforms such documents from their original highly complex, constantly changing, heterogeneous data formats into well-structured, common data formats in using Hypertext Markup Language (HTML) and/or Extensible Markup Language (XML). The software implements an object-relational database system that combines the best practices of the relational model utilizing Structured Query Language (SQL) with those of the object-oriented, semantic database model for creating complex data. In particular, NETMARK takes advantage of the Oracle 8i object-relational database model using physical-address data types for very efficient keyword searches of records across both context and content. NETMARK also supports multiple international standards such as WEBDAV for drag-and-drop file management and SOAP for integrated information management using Web services. The document-organization and -searching capabilities afforded by NETMARK are likely to make this software attractive for use in disciplines as diverse as science, auditing, and law enforcement.

    The relationship between acetylcholinesterase (AChE) activity in the CSF and brain of patients with Alzheimer's disease (AD) was investigated in 18 mild AD patients following galantamine treatment. The first 3 months of the study had a randomized double-blind placebo-controlled design, during which 12 patients received galantamine (16-24 mg/day) and six patients placebo. This was followed by 9 months galantamine treatment in all patients. Activities and protein levels of both the "read-through" AChE (AChE-R) and the synaptic (AChE-S) variants in CSF were assessed in parallel together with the regional brain AChE activity by (11)C-PMP and PET. The AChE-S inhibition was 30-36% in CSF, which correlated well with the in vivo AChE inhibition in the brain. No significant AChE inhibition was observed in the placebo group. The increased level of the AChE-R protein was 16% higher than that of AChE-S. Both the AChE inhibition and the increased level of AChE-R protein positively correlated with the patient's performance in cognitive tests associated with visuospatial ability and attention. In conclusion, AChE levels in CSF closely mirror in vivo brain AChE levels prior to and after treatment with the cholinesterase inhibitors. A positive cognitive response seems to dependent on the AChE inhibition level, which is balanced by an increased protein level of the AChE-R variant in the patients.

    Mouthwashes from human immunodeficiency virus-positive individuals were sampled for yeasts by direct plating on a differential agar medium with and without added fluconazole and via enrichment broths with and without added fluconazole. The colonies of the yeasts isolated were tested for relative growth in the presence of single concentrations of itraconazole and fluconazole. Among 258 culture plates containing yeasts obtained via different isolation routes from 86 yeast-positive samples, 33 (12.7%) of the plates showed unexpectedly high colony-to-colony variation in relative growth. Intercolony variation was seen in 41 (47.7%) of the 86 isolates when relative growth data were analyzed for all colonies of an isolate tested, regardless of the medium used for isolation. The prevalence of relative growth variability with the azoles was highest for Candida glabrata (100% of 13 isolates), followed by Candida krusei (60% of 5 isolates) and Candida albicans (40% of 53 isolates), and the visual patterns of variability seen in scatter plots of the data showed species specificity. Relative growth phenotypes generally tended to be stable for each yeast colony in subcultures, whether or not the medium used for subculture contained antifungal agents. DNA fingerprinting of stable and variable C. albicans isolates showed changes in band patterns detected with the probe Ca3, suggesting that the variability may have resulted from selection of different subtypes of the yeasts during the isolation procedure. These findings suggest that the yeasts isolated from single clinical samples were often not clonal in nature. The relative growth test revealed colony variability more readily than conventional susceptibility testing. PMID:9257732

    Introduction: The aim of this prospective, double-blinded study was to investigate the effects of clonidine in co-administration with bupivacaine during spinal anesthesia, regarding the onset and regression of motor and sensory block, postoperative analgesia and possible side effects. Methods: We randomly selected 66 male patients (age 35 to 70), from the American Society of Anesthesiologists (ASA) class I–II; these patients were scheduled for transurethral surgical procedures. These patients were randomly allocated into two groups of 33 patients each: group B (bupivacaine) only received 0.5% isobaric bupivacaine 7.5 mg intrathecally and group BC (bupivacaine + clonidine) received bupivacaine 7.5 mg and clonidine 25 μg intrathecally. We performed the spinal anesthesia at a level of L3–L4 with a 25-gauge needle. We assessed the sensory block with a pin-prick, the motor block using the Bromage scale, analgesia with the visual analog scale and sedation with the modified Wilson scale. We also recorded the hemodynamic and respiratory parameters. Results: The groups were demographically similar. The mean time of achievement of motor block (Bromage 3) and sensory block at level T9 was significantly shorter in the BC group compared with B group (p = 0.002, p = 0.000, respeectively). The motor block regression time was not significantly different between the two groups (p = 0.237). The postoperative analgesia requirement was significantly longer in group BC compared with group B (p = 0.000). No neurological deficit, sedation or other significant adverse effects were recorded. Conclusion: The intrathecal application of clonidine in combination with bupivacaine improves the duration and quality of spinal anesthesia; it also provides longer duration of postoperative analgesia, without significant side effects.

    Background Despite the availability of high-sensitive troponin (hs-cTnT), there is still room for improvement in the diagnostic assessment of patients suspected of acute coronary syndrome (ACS). Apart from serial biomarker testing, which is time-consuming, novel biomarkers like copeptin have been proposed to expedite the early diagnosis of suspected ACS in addition to hs-cTnT. We determined whether placenta derived growth factor (PlGF), soluble Fms-like tyrosine kinase 1 (sFlt-1), myoglobin, N-terminal prohormone B-type Natriuretic Peptide (NT-proBNP), growth-differentiation factor 15 (GDF-15) and copeptin improved early assessment of chest pain patients. Methods This prospective, single centre diagnostic FAME-ER study included patients presenting to the ED with symptoms suggestive of ACS. Blood was collected to measure biomarkers, notably, hs-cTnT was retrospectively assessed. Added value of markers was judged by increase in AUC using multivariable logistic regression. Results Of 453 patients enrolled, 149 (33%) received a final diagnosis of ACS. Hs-cTnT had the highest diagnostic value in both univariable and multivariable analysis. PPVs of the biomarkers ranged from 23.5% (PlGF) to 77.9% (hs-cTnT), NPVs from 67.0% (PlGF) to 86.4% (hs-cTnT). Only myoglobin yielded diagnostic value in addition to clinical symptoms and electrocardiography (ECG) (AUC of clinical model 0.80) with AUC of 0.84 (p<0.001). However, addition of hs-cTnT was superior (AUC 0.89, p<0.001). Addition of the biomarkers to our clinical model and hs-cTnT did not or only marginally (GDF-15) improved diagnostic performance. Conclusion When assessing patients suspected of ACS, only myoglobin had added diagnostic value beyond clinical symptoms and ECG. However, when combined with hs-cTnT, it yields no additional diagnostic value. PlGF, sFlt-1, NT-proBNP, GDF-15 and copeptin had no added value to the clinical model or hs-cTnT. PMID:26177390

    Introduction Two studies were carried out to investigate the efficacy and safety of luseogliflozin added to existing oral antidiabetic drugs (OADs) in Japanese type 2 diabetic patients inadequately controlled with OAD monotherapy. Materials and Methods In the trial involving add-on to sulfonylureas (study 03-1), patients were randomly assigned to receive luseogliflozin 2.5 mg or a placebo for a 24-week double-blind period, followed by a 28-week open-label period. In the open-label trial involving add-on to other OADs; that is, biguanides, dipeptidyl peptidase-4 inhibitors, thiazolidinediones, glinides and α-glucosidase inhibitors (study 03-2), patients received luseogliflozin for 52 weeks. Results In study 03-1, luseogliflozin significantly decreased glycated hemoglobin at the end of the 24-week double-blind period compared with the placebo (–0.88%, P < 0.001), and glycated hemoglobin reduction from baseline at week 52 was –0.63%. In study 03-2, luseogliflozin added to other OADs significantly decreased glycated hemoglobin from baseline at week 52 (–0.52 to –0.68%, P < 0.001 for all OADs). Bodyweight reduction was observed in all add-on therapies, even with agents associated with weight gain, such as sulfonylureas and thiazolidinediones. Most adverse events were mild in severity. When added to a sulfonylurea, incidences of hypoglycemia during the double-blind period were 8.7% and 4.2% for luseogliflozin and placebo, respectively, but no major hypoglycemic episodes occurred. The frequency and incidences of adverse events of special interest for sodium glucose cotransporter 2 inhibitors and adverse events associated with combined OADs were acceptable. Conclusions Add-on therapies of luseogliflozin to existing OADs improved glycemic control, reduced bodyweight and were well tolerated in Japanese type 2 diabetic patients. These trials were registered with the Japan Pharmaceutical Information Center (add on to sulfonylurea: JapicCTI-111507; add on to

    Patients in hospital intensive care units (ICUs) have to be monitored constantly. Typically, unless the attending physician is at the bedside, he or she has no information of the patient's progress, and must be paged manually in case of emergencies. A far better system would be one that keeps the patient's information available to the doctor or nurse at all times, possibly through the use of a handheld device. The doctor would then be able to check on the patient's progress in real time. Should an emergency arise, the doctor would be notified directly by the monitoring system itself, saving valuable response time. This paper aims to set up an infrastructure for monitoring patients in hospital ICUs. An architectural framework and related protocols to support communication between the various components of such a system are presented. The prototyped product was successfully demonstrated to industry representatives, in November 2005, at Villanova University, PA.

    The current study had four aims: (a) to replicate previous findings of slow response inhibition in Attention Deficit/Hyperactivity Disorder (AD/HD), (b) to explore whether poor response inhibition in children with AD/HD is a core problem or rather a result of an underlying problem related to reward, (c) to investigate the specificity of poor response inhibition and the role of reward in relation to AD/HD, and (d) to study whether findings would be different for three subtypes of AD/HD. In order to address these issues, a stop paradigm was administered under a reward condition and under a nonreward condition to an AD/HD group (n=24), an Oppositional Defiant Disorder (ODD)/Conduct Disorder (CD) group (n=21), a comorbid AD/HD+ODD/CD group (n=27), and a normal control (NC) group (n=41). Firstly, contrary to prediction, none of the Disruptive Behavior Disorder (DBD) groups differed from the NC group with respect to the speed of the inhibition process. Secondly, it was shown that children with AD/HD and children with comorbid AD/HD+ODD/CD, but not children with ODD/CD alone, slowed down more dramatically in the reward condition than normal controls. This finding was interpreted as a strategy to increase the chance of being rewarded in children with AD/HD and children with comorbid AD/HD+ODD/CD, but not in children with pure ODD/CD. Finally, analysis of AD/HD subtypes did not change the main findings of this study.

    An experiment (N=123) examined how individuals cognitively process online news stories depicting African-American characters with stereotype-consistent and -inconsistent attributes and whether distracting online ads interfere with story processing. Two cognitive control functions, updating and inhibition, were predicted to moderate the effects of distracting ads. Recall of characters' attributes and overall characters' description were included in the study as dependent measures. Findings indicated that distracting online ads hinder recall of information about and descriptions of story characters. Inhibition and updating affect dependent measures and moderate the effects of distracting online ads on characters' descriptions.

    Background: Osteoporosis is a major public health problem affecting the elderly population, particularly women. The objective of the study was to evaluate the effects of adding weight-bearing exercise as opposed to nonweight-bearing programs to the medical treatment of bone mineral density (BMD) and health-related quality of life (HRQoL) of elderly patients with osteoporosis. Materials and Methods: Participating in the study were 40 elderly osteoporotic patients (27 females and 13 males), with ages ranging from 60 to 67 years, who were receiving medical treatment for osteoporosis. They were assigned randomly into two groups: Group-I: Twenty patients practiced weight-bearing exercises. Group-II: Twenty patients did nonweight-bearing exercises. All patients trained for 45-60 min/session, two sessions/week for 6 months. BMD of the lumbar spine, right neck of femur, and right distal radial head of all patients were measured by dual-energy X-ray absorptiometry before and after both treatment programs. In addition, the QoL was measured by means of the HRQoL “ECOS-16” questionnaire. Results: T-tests proved that mean values of BMD of the lumbar spine, right neck of femur and right distal radial head were significantly increased in both groups with greater improvement in the weight-bearing group. The QoL was significantly improved in both groups, but the difference between them was not significant. Conclusion: Addition of weight-bearing exercise program to medical treatment increases BMD more than nonweight-bearing exercise in elderly subjects with osteoporosis. Furthermore, both weight-bearing and nonweight-bearing exercise programs significantly improved the QoL of patients with osteoporosis. PMID:25374469

    Alzheimer disease (AD) is the most common form of dementia among the elderly and is characterized by progressive loss of memory and cognition. Amyloid-ß-peptide (Aß) forms senile plaques, which, together with hyperphosphorylated tau-based neurofibrillary tangles, are the hallmarks of AD neuropathology. Evidence support the involvement of immune system in AD progression and current concepts regarding its pathogenesis include the participation of inflammatory and autoimmune components in the neurodegenerative process. Pathologically, immune system components have been detected in the brain, cerebrospinal fluid (CSF) and in serum of AD subjects and their trend of variation correlates with disease progression. However, patients with AD present significantly lower levels of antibody immunoreactivity against Aß in serum and CSF than healthy controls suggesting that a depletion of such patrolling system is involved in the deposition of toxic aggregates in AD. Within this frame, incomplete and often controversial results are reported about CNS immune/ autoimmune responses during AD, and a better comprehension of such processes is needed. Our research will aim to shed light on the nature and potential role of autoantibodies in CSF and serum from AD and amnestic mild cognitive impairment (aMCI) patients compared to healthy subjects by using an immunoproteomics approach. Our method allows recognition of natural occurring antibodies by the identification of brain antigen targeted by human IgGs. Overall our data reveal that the alterations of autoantibodies profile both in CSF and serum follow disease staging and progression. However, we demonstrate a fair overlap between CSF and serum suggesting the existence of different immunogenic events. Interestingly, CSF autoantibodies recognized, among others, key players of energy metabolic pathway, including glycolysis and TCA cycle, found oxidatively modified in AD brain studies. These data suggest a potential casual sequence

    We investigated the relationship of caregivers' health-related quality of life (HRQOL) to the burden of caring for patients with Alzheimer disease (AD) and resource utilization. Caregiver HRQOL was assessed using the SF-12 Mental and Physical Summary scores. Compared with a normative, age-adjusted sample, the 2477 caregivers had lower mental and physical scores (for the latter, only those <54 years of age). Increased caregiver mental functioning was associated with caregiver support and perceived quality of patient medical care, fewer hours of caregiving, and fewer patient behavioral symptoms. The burden of caregiving has substantial effects on HRQOL. Interventions that improve AD status and reduce caregiving hours have the potential to improve caregivers' HRQOL.

We examine their thermodynamic properties and discuss the role of these solutions for the existence of first order phase transitions for hairy black holes. The negative energy density associated to hairy AdS solitons can be interpreted as the Casimir energy that is generated in the dual filed theory when the fermions are antiperiodic on the compact coordinate.

    Background Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are chronic, debilitating, and life-threatening conditions. Riociguat is the first and only pharmacotherapy approved by the US Food and Drug Administration (FDA) for the treatment of PAH and for CTEPH in patients who are either inoperable or have persistent pulmonary hypertension after surgery. Objective To estimate the budgetary impact of adding riociguat to a US health plan's formulary for the treatment of patients with PAH or CTEPH using a budget impact analytic model. Methods A customizable, Microsoft Excel–based decision analytic tool was developed to estimate the impact of riociguat on per-member per-month (PMPM) and per-member per-year (PMPY) bases in Medicare and non-Medicare health plans. The economic impact was calculated based on 1 million insured lives, published prevalence estimates of PAH and CTEPH, pharmacotherapy-eligible patients with PAH or CTEPH, administration costs, and monitoring costs related to pharmacotherapy. The drug costs were based on wholesale acquisition costs, and the medical costs were derived from Truven Health MarketScan claims data and the Medicare 2013 Clinical Diagnostic Laboratory Fee Schedule and Physician Fee Schedule. The market share for approved treatments was based on a tracking study of physicians treating patients with PAH or CTEPH. A sensitivity analysis was used to test the model's robustness. Results In a hypothetical plan population of 1 million members, the model estimated that 7 patients with PAH and 2 patients with CTEPH would be suitable for pharmacotherapy. Overall, 3 patients (1 with PAH and 2 with CTEPH) were receiving riociguat in a health plan consisting of patients with commercial and with Medicare insurance coverage. The incremental PMPY and PMPM costs for providing insurance coverage for riociguat were $0.27 and $0.02, respectively, for non-Medicare and Medicare health plans. Sensitivity analyses

    Enteric Escherichia coli infections are a highly relevant cause of disease and death in young pigs. Breeding genetically resistant pigs is an economical and sustainable method of prevention. Resistant pigs are protected against colonization of the intestine through the absence of receptors for the bacterial fimbriae, which mediate adhesion to the intestinal surface. The present work aimed at elucidation of the mode of inheritance of the F4ad receptor which according to former investigations appeared quite confusing. Intestines of 489 pigs of an experimental herd were examined by a microscopic adhesion test modified in such a manner that four small intestinal sites instead of one were tested for adhesion of the fimbrial variant F4ad. Segregation analysis revealed that the mixed inheritance model explained our data best. The heritability of the F4ad phenotype was estimated to be 0.7±0.1. There are no relations to the strong receptors for variants F4ab and F4ac. Targeted matings allowed the discrimination between two F4ad receptors, that is, a fully adhesive receptor (F4adRFA) expressed on all enterocytes and at all small intestinal sites, and a partially adhesive receptor (F4adRPA) variably expressed at different sites and often leading to partial bacterial adhesion. In pigs with both F4ad receptors, the F4adRPA receptor is masked by the F4adRFA. The hypothesis that F4adRFA must be encoded by at least two complementary or epistatic dominant genes is supported by the Hardy-Weinberg equilibrium statistics. The F4adRPA receptor is inherited as a monogenetic dominant trait. A comparable partially adhesive receptor for variant F4ab (F4abRPA) was also observed but the limited data did not allow a prediction of the mode of inheritance. Pigs were therefore classified into one of eight receptor phenotypes: A1 (F4abRFA/F4acR+/F4adRFA); A2 (F4abRFA/F4acR+/F4adRPA); B (F4abRFA/F4acR+/F4adR-); C1 (F4abRPA/F4acR-/F4adRFA); C2 (F4abRPA/F4acR-/F4adRPA); D1 (F4abR-/F4acR-/F4ad

    Patients with Alzheimer's disease (AD) show cognitive and behavioral disorders, which they and their caregivers have difficulties to cope with in daily life. Psychological symptoms seem to be increased by impaired emotion processing in patients, this ability being linked to social cognition and thus essential to maintain good interpersonal relationships. Non-verbal emotion processing is a genuine way to communicate, especially so for patients whose language may be rapidly impaired. Many studies focus on emotion identification in AD patients, mostly by means of facial expressions rather than emotional prosody; even fewer consider emotional prosody production, despite its playing a key role in interpersonal exchanges. The literature on this subject is scarce with contradictory results. The present study compares the performances of 14 AD patients (88.4±4.9 yrs; MMSE: 19.9±2.7) to those of 14 control subjects (87.5±5.1 yrs; MMSE: 28.1±1.4) in tasks of emotion identification through faces and voices (non linguistic vocal emotion or emotional prosody) and in a task of emotional prosody production (12 sentences were to be pronounced in a neutral, positive, or negative tone, after a context was read). The Alzheimer's disease patients showed weaker performances than control subjects in all emotional recognition tasks and particularly when identifying emotional prosody. A negative relation between the identification scores and the NPI (professional caregivers) scores was found which underlines their link to psychological and behavioral disorders. The production of emotional prosody seems relatively preserved in a mild to moderate stage of the disease: we found subtle differences regarding acoustic parameters but in a qualitative way judges established that the patients' productions were as good as those of control subjects. These results suggest interesting new directions for improving patients' care.

    Chemotherapy-related cognitive impairment (CRCI) can occur during or after chemotherapy and represents a concern for many patients with cancer. Among older patients with cancer, in whom there is little clinical trial evidence examining side effects like CRCI, many unanswered questions remain regarding risk for and resulting adverse outcomes from CRCI. Given the rising incidence of cancer with age, CRCI is of particular concern for older patients with cancer who receive treatment. Therefore, research related to CRCI in older patients with cancers is a high priority. In this manuscript, we discuss current gaps in research highlighting the lack of clinical studies of CRCI in older adults, the complex mechanisms of CRCI, and the challenges in measuring cognitive impairment in older patients with cancer. Although we focus on CRCI, we also discuss cognitive impairment related to cancer itself and other treatment modalities. We highlight several research priorities to improve the study of CRCI in older patients with cancer. PMID:27197918

    Paleosols buried under kurgans of the Early (2nd-1st centuries BC), Middle (1st-2nd centuries AD) and Late (2nd-IV centuries AD) Sarmatian epochs were studied in dry steppes and desert steppes of the Lower Volga region (the Privolzhskaya and Ergeni Uplands and the Caspian Lowland). It was found that temporal variations in the morphological, chemical, microbiological, and magnetic properties of the paleosols in the interval of 2200-1600 BP were characterized by the cyclic pattern related to secular dynamics of climatic humidity with changes in the mean annual precipitation of ±30-50 mm. These climate changes did not transform chestnut paleosols and paleosolonetzes at the type or subtype taxonomic levels. However, they led to certain changes in the humus, carbonate, and salt profiles of the soils; in the character of solonetzic horizon B1; and in the state of microbial communities. According to these data, the Sarmatian time was characterized by alternation of micropluvial and microarid stages lasting fro about 100-200 years. In particular, the stages of humidization were observed in the 1st century BC-1st century AD and in the 4th century AD; the most arid conditions were observed in the second half of the 2nd and the first half of the 3rd century AD.

    Sixty-nine unselected SLE patients were studied to evaluate the prevalence of avascular osteonecrosis (AVN) and its relationship with steroid therapy and with anticardiolipin antibodies (aCL). All the patients were under treatment with corticosteroids. AVN occurred in seven occurred in seven of the 69 patients (10.14%) and was not related to corticosteroid intake. Seventeen of the 69 patients were also treated with methylprednisolone pulse therapy (MPPT) and cumulated the highest corticosteroid doses but none of them suffered from AVN. Excluding the 17 MPPT-treated SLE patients, corticosteroid intake was significantly higher in the AVN-SLE patients. Abnormal IgG and/or IgM aCL serum levels were found in two of the seven AVN-SLE patients and in 24 of the 62 non-AVN SLE, without a statistically significant difference. None of the seven AVN-SLE patients showed features of antiphospholipid syndrome. We conclude that in SLE patients a continuous high-dose steroid treatment may be considered a risk factor for AVN. On the contrary, MPPT regimen may reduce this risk. Anticardiolipin antibodies might represent an added factor which could play a role in some patients but not in all. PMID:8025584

    To identify patient-related risk factors for venous thrombosis in patients with central venous catheters (CVC) or peripherally inserted central catheters (PICC). We performed a systematic review of the literature assessing patient-related risk factors for thrombosis related to CVC or PICC. The databases PubMed, Ovid and the Cochrane library were searched for observational studies pertaining to patient-related risk factors for CVC and PICC-related thrombosis. The initial search through PubMed, Ovid and the Cochrane library yielded 516 results. After 71 duplicates were removed, 445 articles were assessed for eligibility based on title and abstract. Four hundred and eleven articles were then excluded and 33 full text articles were manually assessed for eligibility. Eight articles were eliminated as they did not contain content relevant to the review. Twenty-five studies were then selected to assess 20 risk factors. There were no consistent significant associations for catheter-related thrombosis across the twenty-five studies. Multiple studies identified age, malignancy, diabetes, obesity, chemotherapy, thrombophilia and a history of thrombosis as significant risk factors for catheter-related thrombosis. Inconsistent findings among studies make it difficult to establish which patient-related risk factors are associated with catheter-related thrombosis. Future studies could include larger sample sizes and more cases of catheter-related thrombosis to produce more significant results. Identification of patient-related risk factors could lead to early recognition of upper limb deep vein thrombosis in patients with catheters, thereby preventing complications.

    Objective While acetylcholinesterase inhibitors, such as donepezil, galantamine, and rivastig-mine, are beneficial in treating behavioral symptoms of patients with Alzheimer’s disease (AD), their dose-limiting effects include gastrointestinal disturbances, such as nausea, vomiting, and diarrhea. We aimed to predict the occurrence of these gastrointestinal disturbances with rivastigmine therapy for optimal drug choice and improved compliance. Materials and methods Thirty patients with mild-to-moderate AD (scores 10–22 on the MiniMental State Examination) were administered a rivastigmine 18 mg patch with domperidone 30 mg (RWD) and without domperidone (RWOD; n = 15 each) for 20 weeks. Gastrointestinal disturbances were evaluated using a frequency scale for symptoms of gastroesophageal reflux disease (FSSG), Bristol stool form scale, laboratory data (hemoglobin, albumin, total cholesterol), body weight, and amount of food intake. Results After 12 weeks, FSSG scores were higher in the RWOD group compared to baseline scores; however, no significant differences were noted between the RWD and RWOD groups. We then subdivided each group based on high and low baseline scores; the RWOD high-score (≥4) subgroup showed increased FSSG after 12 weeks compared with the baseline score. In both RWD and RWOD groups, the low-score (≤3) subgroups showed no changes during the dose-escalation phase. Conclusion For AD patients with higher FSSG scores at baseline, domperidone was effective in preventing rivastigmine-related gastrointestinal disturbances. PMID:24092978

  16. Call 4 Concern: patient and relative activated critical care outreach.

    Patients can experience unexpected deterioration in their physiological condition that can lead to critical illness, cardiac arrest, admission to the intensive care unit and death. While ward staff can identify deterioration through monitoring physiological signs, these signs can be missed, interpreted incorrectly or mismanaged. Rapid response systems using early warning scores can fail if staff do not follow protocols or do not notice or manage deterioration adequately. Nurses often notice deterioration intuitively because of their knowledge of individual patients. Patients and their relatives have the greatest knowledge of patients, and can often pick up subtle signs physiological deterioration before this is identified by staff or monitoring systems. However, this ability has been largely overlooked. Call 4 Concern (C4C) is a scheme where patients and relatives can call critical care teams directly if they are concerned about a patient's condition- it is believed to be the first of its kind in the UK. A C4C feasibility project ran for six months, covering patients being transferred from the intensive care unit to general wards. C4C has the potential to prevent clinical deterioration and is valued by patients and relatives. Concerns of ward staff could be managed through project management. As it is relatively new, this field offers further opportunities for research. PMID:21139519

    A technique is described for registering centric relation in dentate patients using an anterior deprogrammer to prevent muscle splinting. Properly executed, the patient is able to close into centric relation unassisted, eliminating the possibility of operator-induced error associated with commonly accepted manipulative techniques. Verification is possible visually when articulating casts by confirming the precise alignment of the mandibular incisors with occlusal markings on the deprogrammer attached to the maxillary cast.

    Objective: At present, inhibition of cholines-terase is the treatment of choice for subjects with mild-to-moderate Alzheimer's disease (AD). Memantine, a noncompetitive antagonist at N-methyl-d-aspartate receptors, is currently used to treat subjects with moderate-to-severe AD. The goal of this multicenter, open-label pilot study was to investigate whether combination therapy with memantine added to rivastigmine is safe and beneficial in subjects with mild-to-moderate AD. Method: Patients with a DSM-IV diagnosis of dementia of the Alzheimer's type (N = 95), who were treated with rivastigmine (6–12 mg/day) for a maximum duration of 24 weeks prior to baseline, received memantine (5–20 mg/day) in combination with rivastigmine for 12 weeks. The primary efficacy variable was the change in the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) total score at the end of 12 weeks compared with baseline. The study was conducted between September 15, 2003, and May 27, 2004. Results: There was a statistically significant difference between baseline and week 12 for the ADAS-cog total score, showing a positive effect of combination therapy. Combination therapy did not evidence any unexpected safety concerns and was well-tolerated by most patients. Conclusion: Memantine in combination with rivastigmine appears to be safe and beneficial in patients with mild-to-moderate AD. Our results need to be confirmed in a large, long-term, randomized, double-blind, placebo-controlled clinical trial. PMID:17235381

    It has been reported that autism is a hypoglutamatergic disorder. Therefore, it was of interest to assess the efficacy of piracetam, a positive modulator of AMPA-sensitive glutamate receptors in autistic disorder. About 40 children between the ages three and 11 years (inclusive) with a DSM IV clinical diagnosis of autism and who were outpatients from a specialty clinic for children were recruited. The children presented with a chief complaint of severely disruptive symptoms related to autistic disorder. Patients were randomly allocated to piracetam + risperidone (Group A) or placebo + risperidone (Group B) for a 10-week, double-blind, placebo-controlled study. The dose of risperidone was titrated up to 2 mg/day for children between 10 and 40 kg and 3 mg/day for children weighting above 40 kg. The dose of piracetam was titrated up to 800 mg/day. Patients were assessed at baseline and after 2, 4, 6, 8 and 10 weeks of starting medication. The measure of the outcome was the Aberrant Behavior Checklist-Community (ABC-C) Rating Scale (total score). The ABC-C Rating Scale scores improved with piracetam. The difference between the two protocols was significant as indicated by the effect of group, the between subjects factor (F = 5.85, d.f. = 1, P = 0.02). The changes at the endpoint compared with baseline were: -11.90 +/- 3.79 (mean +/- SD) and -5.15 +/- 3.04 for group A and B respectively. A significant difference was observed on the change in scores in the ABC-C Rating Scale in week 10 compared with baseline in the two groups (t = 6.017, d.f. = 38, P < 0.0001). The results suggest that a combination of atypical antipsychotic medications and a glutamate agent such as piracetam, might have increase synergistic effects in the treatment of autism.

    In response to the evolution of the information-seeking behaviour of patients and concerns from health professionals regarding cancer patient information, the French National Federation of Comprehensive Cancer Centres (FNCLCC) introduced, in 1998, an information and education program dedicated to patients and relatives, the SOR SAVOIR PATIENT program (SSP). The methodology of this program adheres to established quality criteria regarding the elaboration of patient information. Cancer patient information, developed in this program, is based on clinical practice guidelines produced by the FNCLCC and the twenty French cancer centres, the National League against Cancer, The National Cancer Institute, the French Hospital Federation, the National Oncology Federation of Regional and University Hospitals, the French Oncology Federation of General Hospitals, many learned societies, as well as an active participation of patients, former patients and caregivers. The information and dialogue handbook SOR SAVOIR PATIENT Vivre pendant et après un cancer reporting on the psychological aspects of cancer was worked out and published on the Web in 2005. The guide aims to provide cancer patients with support and advice about the psychological impact of the disease. It provides information on the possible personal consequences of the disease and treatments, in every domain: psychological, emotional, interpersonal, familial or professional. Patients are also advised of the emotional challenges associated with cancer, of the support they may expect at every stage of the disease, from diagnosis to treatment, and of psychological outcome after the disease is over. The document also provides healthcare professionals with a valuable, concise source of validated information on the psychological aspects of cancer, thus facilitating communication between carers and patients. Information provided in the present article has been selected from the information and dialogue handbook SOR SAVOIR

    Treatment of patients with hepatitis-B-related or hepatitis-C-related decompensated cirrhosis should focus on controlling the complications of cirrhosis, surveillance for hepatocellular carcinoma and, if applicable, preparation for orthotopic liver transplant. Interferon-based regimens for the treatment of hepatitis C have been somewhat successful in patients with cirrhosis, although treatment of patients with decompensated cirrhosis should be approached with caution. Given the potential for exacerbation of decompensation and poor tolerance of adverse effects, treatment should be reserved for those patients awaiting liver transplantation. Eradication of HCV before liver transplantation reduces the chances of recurrent hepatitis C infection after transplant. HBV can be treated with few adverse effects in patients with decompensated cirrhosis. This treatment is associated with improvement in decompensation in some patients. Hepatocellular carcinoma remains a significant risk in all patients with cirrhosis, and control of or eradication of HBV or HCV does not remove this risk. PMID:21695841

    Introduction Cancer patients are at risk for severe complications related to the underlying malignancy or its treatment and, therefore, usually require admission to intensive care units (ICU). Here, we evaluated the clinical characteristics and outcomes in this subgroup of patients. Materials and Methods Secondary analysis of two prospective cohorts of cancer patients admitted to ICUs. We used multivariable logistic regression to identify variables associated with hospital mortality. Results Out of 2,028 patients, 456 (23%) had cancer-related complications. Compared to those without cancer-related complications, they more frequently had worse performance status (PS) (57% vs 36% with PS≥2), active malignancy (95% vs 58%), need for vasopressors (45% vs 34%), mechanical ventilation (70% vs 51%) and dialysis (12% vs 8%) (P<0.001 for all analyses). ICU (47% vs. 27%) and hospital (63% vs. 38%) mortality rates were also higher in patients with cancer-related complications (P<0.001). Chemo/radiation therapy-induced toxicity (6%), venous thromboembolism (5%), respiratory failure (4%), gastrointestinal involvement (3%) and vena cava syndrome (VCS) (2%) were the most frequent cancer-related complications. In multivariable analysis, the presence of cancer-related complications per se was not associated with mortality [odds ratio (OR) = 1.25 (95% confidence interval, 0.94–1.66), P = 0.131]. However, among the individual cancer-related complications, VCS [OR = 3.79 (1.11–12.92), P = 0.033], gastrointestinal involvement [OR = 3.05 (1.57–5.91), P = <0.001] and respiratory failure [OR = 1.96(1.04–3.71), P = 0.038] were independently associated with in-hospital mortality. Conclusions The prognostic impact of cancer-related complications was variable. Although some complications were associated with worse outcomes, the presence of an acute cancer-related complication per se should not guide decisions to admit a patient to ICU. PMID:27764143

    We used longitudinal magnetic resonance imaging (MRI) data to determine whether there are any gender differences in grey matter atrophy patterns over time in 197 individuals with probable Alzheimer’s disease (AD) and 266 with amnestic mild cognitive impairment (aMCI), compared with 224 healthy controls participating in the Alzheimer’s Disease Neuroimaging Initiative (ADNI). While previous research has differentiated probable AD and aMCI groups from controls in brain atrophy, it is unclear whether and how sex plays a role in patterns of change over time. Using regional volumetric maps, we fit longitudinal models to the grey matter data collected at repeated occasions, seeking differences in patterns of volume change over time by sex and diagnostic group in a voxel-wise analysis. Additionally, using a region-of-interest approach, we fit longitudinal models to the global volumetric data of predetermined brain regions to determine whether this more conventional approach is sufficient for determining sex and group differences in atrophy. Our longitudinal analyses revealed that, of the various grey matter regions investigated, males and females in the AD group and the aMCI group showed different patterns of decline over time compared to controls in the bilateral precuneus, bilateral caudate nucleus, right entorhinal gyrus, bilateral thalamus, bilateral middle temporal gyrus, left insula, and right amygdala. As one of the first investigation to model more than two time points of structural MRI data over time, our findings add insight into how AD and aMCI males and females differ from controls and from each other over time.

    PCDH19 gene mutations have been recently associated with an epileptic syndrome characterized by focal and generalized seizures. The PCDH19 gene (Xq22.1) has an unusual X-linked inheritance with a selective involvement for female subjects. A cellular interference mechanism has been hypothesized and male patients can manifest epilepsy only in the case of a mosaicism. So far about 100 female patients, and only one symptomatic male have been described. Using targeted next generation sequencing (NGS) approach we found a PCDH19 point mutation in two male patients with a clinical picture suggestive of PCDH19-related epilepsy. The system allowed us to verify that the two c.1352 C>T; p.(Pro451Leu) and c.918C>G; p.(Tyr306*) variants occurred in mosaic status. Mutations were confirmed by Sanger sequencing and quantified by real-time polymerase chain reaction (PCR). Up to now, the traditional molecular screening for PCDH19-related epilepsy has been targeted to all females with early onset epilepsy with or without cognitive impairment. Male patients were generally excluded. We describe for the first time two mosaic PCDH19 point mutations in two male patients with a clinical picture suggestive of PCDH19-related epilepsy. This finding opens new opportunities for the molecular diagnoses in patients with a peculiar type of epilepsy that remains undiagnosed in male patients.

    Patients who seek medical care for stress-related mental health problems frequently report cognitive impairments as the most pronounced symptom. The purpose of the present study was to compare cognitive function in patients with stress-related exhaustion with that in healthy controls, using a comprehensive battery of cognitive tests. We also explored whether neuropsychological findings were related to severity of illness measured using the Shirom-Melamed burnout questionnaire and hospital anxiety and depression scale. Thirty-three patients (15 males) and 37 healthy controls (11 males), mean age 46 years [standard deviation (SD) 3.9] and 47 years (SD 4.3), respectively, were included in the final analysis. Five cognitive domains were assessed: (1) speed, attention and working memory, (2) learning and episodic memory, (3) executive functions, (4) visuospatial functions and (5) language. The most pronounced difference between patients and controls was seen on executive function, when tested with a multidimensional test, including aspects of speed, control and working memory. The patients also performed poorer on Digit span, measuring attention span and working memory as well as on learning and episodic memory, when measured as delayed recall and the difference between immediate and delayed recall. Delayed recall was the only test that was significantly related to severity of burnout symptoms among the patients. This could reflect poor cognitive sustainability in the patients with the highest burnout scores, as this particular test was the last one performed during the test session. This study clearly shows that cognitive impairment should be considered when evaluating and treating patients who seek medical care for stress-related exhaustion.

    Plasma aluminum (pAl) was measured in 58 patients coming from three centers using different preparation of dialysis water: deionizer (29 patients), softener (16 patients) and reverse osmosis (13 patients). Twenty five healthy subjects were used as controls. A deferoxamine test was performed to 11 of 19 patients with pAl between 40 and 200 micrograms/dl and a bone biopsy with double tetracycline staining was executed to 15 patients with pAl over 40 micrograms/dl. Mean pAl was 9.5 +/- 1.7 micrograms/dl in controls and 34.3 +/- 6.1 169 +/- 27.8 and 50.8 +/- 10.3 micrograms/dl in patients coming form centers using deionizers, softeners and reverse osmosis respectively. Seventy six percent of patients coming from centers using deionizers and 85% of patients coming from centers with reverse osmosis had pAl below 40 micrograms/dl and all had values below 200 micrograms/dl. Plasma aluminum had a increase of over 200 micrograms/dl in 6 of 11 patients in which the deferoxamine test was performed. Six patients had a positive staining for aluminum in bone biopsies (three with basal pAl over 200 micrograms/dl and one with a increase in pAL after deferoxamine < 200 micrograms/dl). Of these, 2 patients had a mixed osteodystrophy and 4 a low turnover bone disease. Centers with deionizers and reverse osmosis had very low aluminum levels in dialysis water and five of six patients with aluminum levels related bone disease came from the center using softener.

    This study sought to identify factors that increase or decrease patient time with a physician, determine which combinations of factors are associated with the shortest and longest visits to physicians, quantify how much physicians contribute to variation in the time they spend with patients, and assess how well patient time with a physician can be predicted. Data were acquired from a modified replication of the 1997-1998 National Ambulatory Medical Care Survey, administered by the Kentucky Ambulatory Network to 56 primary care clinicians at 24 practice sites in 2001 and 2002. A regression tree and a linear mixed model (LMM) were used to discover multivariate associations between patient time with a physician and 22 potentially predictive factors. Patient time with a physician was related to the number of diagnoses, whether non-illness care was received, and whether the patient had been seen before by the physician or someone at the practice. Approximately 38% of the variation in patient time with a physician was accounted for by predictive factors in the tree; roughly 33% was explained by predictive factors in the LMM, with another 12% linked to physicians. Knowledge of patient characteristics and needs could be used to schedule office visits, potentially improving patient flow through a clinic and reducing waiting times. PMID:21393556

    Patients with bisphosphonate-related osteonecrosis of the jaws (BRONJ) who received intravenous or oral bisphosphonates (BP) were selected for determination of their bone microarchitecture as a risk predictor of BRONJ development. The diagnosis of BRONJ was made based on clinical and radiographic findings. The control group consisted of healthy patients. All patients underwent quantitative and qualitative ultrasound measurements of bone at the hand phalanges carried out using the DBM Sonic BP. Ultrasound bone profile index (UBPI), amplitude-dependent speed of sound (AD-SoS), bone biophysics profile (BBP), and bone transmission time (BTT) were measured. The BRONJ group consisted of 17 patients (62 ± 4.24; range: 45-82); 10 (58.8%) were male and seven (41.1%) were female, of whom 11 (64.7%) suffered from multiple myeloma, three (17.6%) from osteoporosis, one (5.8%) from prostate cancer, one (5.8%) from kidney cancer, and one (5.8%) from leukemia. Fourteen (82.3%) of them received intravenous BP whereas three (17.6%) received oral BP. Nine (9/17; 52.9%) patients developed bone exposure: two in the maxilla and seven in the mandible. Regarding quantitative parameters, Ad-SoS was low in the BRONJ group, but not significant. The UBPI score was significantly reduced in BRONJ patients with exposed bone when compared to controls (0.47 ± 0.12 vs. 0.70 ± 0.15; p = 0.004). The present study demonstrated that quantitative ultrasound was able to show bone microarchitecture alterations in BRONJ patients, and suggests that these analyses may be an important tool for early detection of bone degeneration associated with BRONJ.

    Patients with anatomic or functional asplenia have a 10-50 times higher risk than general population to develop Overwhelming Post-Splenectomy Infection. Evidences are unanimous in recommending splenectomised patients to receive meningococcal, antipneumococcal and Haemophilus influenzae type B vaccinations according to a specific timing. In Italy there are no current data on the immunisation coverage in these patients. This study aims to investigate immunisation coverage in patients undergoing elective or urgent splenectomy for 2012-2013 in the 3 Apulian hospitals. The patients discharged with the code ICD-9-CM 41.5 - "Total splenectomy" were enrolled. The administration of vaccines was verified through consultation of medical records, archives of general practitioners and vaccination offices. In the study period, 166 subjects underwent splenectomy and none of them received vaccinations during hospitalization. 25 splenectomised patients (15.1%) received at least one of the recommended vaccinations. 21 patients (12.6%) received vaccine against Streptococcus pneumonia, 13 (7.8%) meningococcal vaccine, 10 patients (6%) Haemophilus influenzae type B vaccine. The low vaccination coverage could be due both to poor perception of the risk of infection and to a lack of knowledge on vaccinations by surgeons. For this reason it is necessary to draw up and share operational protocols that establish the administration of vaccines. PMID:26890256

Evidences are unanimous in recommending splenectomised patients to receive meningococcal, antipneumococcal and Haemophilus influenzae type B vaccinations according to a specific timing. In Italy there are no current data on the immunisation coverage in these patients. This study aims to investigate immunisation coverage in patients undergoing elective or urgent splenectomy for 2012-2013 in the 3 Apulian hospitals. The patients discharged with the code ICD-9-CM 41.5 - "Total splenectomy" were enrolled. The administration of vaccines was verified through consultation of medical records, archives of general practitioners and vaccination offices. In the study period, 166 subjects underwent splenectomy and none of them received vaccinations during hospitalization. 25 splenectomised patients (15.1%) received at least one of the recommended vaccinations. 21 patients (12.6%) received vaccine against Streptococcus pneumonia, 13 (7.8%) meningococcal vaccine, 10 patients (6%) Haemophilus influenzae type B vaccine. The low vaccination coverage could be due both to poor perception of the risk of infection and to a lack of knowledge on vaccinations by surgeons. For this reason it is necessary to draw up and share operational protocols that establish the administration of vaccines.

    High patient drop-out rates have traditionally interfered with both treatment and study of patients with borderline personality disorder (BPD). The authors tested hypotheses that an adequate treatment contract, a positive therapeutic alliance, and the severity of illness would all correlate with continuation of treatment versus drop-out in a BPD cohort receiving psychodynamic psychotherapy. Therapists’ contributions to the contract and to the alliance correlated with the length of treatment. Patients’ impulsivity was negatively related to length of treatment. This study supports the view that the therapist’s technique plays a role in engaging the borderline patient to remain in treatment. PMID:22700170

  16. Note about a pure spin-connection formulation of general relativity and spin-2 duality in (A)dS

    We investigate the problem of finding a pure spin-connection formulation of general relativity with nonvanishing cosmological constant. We first revisit the problem at the linearized level and find that the pure spin-connection, quadratic Lagrangian, takes a form reminiscent to Weyl gravity, given by the square of a Weyl-like tensor. Upon Hodge dualization, we show that the dual gauge field in (A )dSD transforms under G L (D ) in the same representation as a massive graviton in the flat spacetime of the same dimension. We give a detailed proof that the physical degrees of freedom indeed correspond to a massless graviton propagating around the (anti-) de Sitter background and finally speculate about a possible nonlinear pure-connection theory dual to general relativity with cosmological constant.

    In search for biomarkers of neurodegeneration, increasing attention has been focussed on peripheral blood mononuclear cells (PBMC). In particular, PBMC from patients with Alzheimer disease (AD) have been suggested to carry apoptotic changes and alterations of neurotransmitter receptor expression, which may resemble those occurring in central nervous system neurons. We investigated the expression of apoptosis-related proteins Bcl-2, Bax, and caspase-3 and the levels of dopaminergic receptors (DR) D3 and D5 mRNA in PBMC from 17 AD patients and 11 age-matched healthy subjects. Apoptosis-related proteins were assayed by standard Western blotting analysis and DR mRNA by real-time polymerase chain reaction techniques. PBMC from healthy subjects and from AD patients expressed Bcl-2, Bax, and caspase-3 to about the same extent, and the Bcl-2/Bax ratio did not differ in the 2 groups. Levels of mRNA for DRD3 and DRD5 were similar in cells from healthy subjects and from AD patients. In conclusion, we found no evidence that PBMC from AD patients may express apoptosis-related proteins or DR mRNA to any different extent in comparison to cells from healthy subjects. These findings do not necessarily imply that immune cells cannot be exploited as biomarkers in AD (and in other central nervous system disorders). Future studies, however, should take into account the inherent complexity of the immune network.

    Introduction. Increased levels of stress hormones are associated with mortality in patients undergoing coronary artery bypass grafting (CABG). Aim. To compare total intravenous anaesthesia (TIVA) and desflurane added to a subanaesthetic dose of propofol. Material and Methods. Fifty patients were enrolled in this study. Fentanyl (3–5 mcg/kg/h) was started in both groups. Patients were divided into two groups. The PD group (n = 25) received 1 minimum alveolar concentration (MAC) desflurane anaesthesia in addition to propofol infusion (2-3 mg/kg/h), while P group (n = 25) received propofol infusion (5-6 mg/kg/h) only. Biochemical data, cortisol, and insulin levels were measured preoperatively (T0), after initiation of CPB but before cross-clamping the aorta (T1), after removal of the cross-clamp (T2), and at the 24th postoperative hour (T3). Results. Systolic, diastolic, and mean arterial pressure levels were significantly higher in PD group than those in P group in T1 and T2 measurements (p ≤ 0.05). CK-MB showed a significant decrease in group P (p ≤ 0.05). When we compared both groups, cortisol levels were significantly higher in PD group than P group (p ≤ 0.05). Conclusion. Stress and haemodynamic responses were better controlled using TIVA than desflurane inhalation added to a subanaesthetic dose of propofol in patients undergoing CABG. PMID:27547757

    Benefits of triple therapy with a long-acting muscarinic antagonist (LAMA), added to inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA), have been demonstrated. Limited data assessing the efficacy of the LAMA umeclidinium (UMEC) added to ICS/LABA are available. The aim of this study is to evaluate the efficacy and safety of UMEC added to ICS/LABAs in patients with moderate-to-very-severe COPD. This is a multicentre, randomised, double-blind, parallel-group study. Patients were symptomatic (modified Medical Research Council Dyspnoea Scale score ⩾2), despite receiving ICS/LABA (fluticasone propionate/salmeterol (FP/SAL, branded) 500/50 mcg, budesonide/formoterol (BD/FOR, branded) 200/6 mcg or 400/12 mcg, or other ICS/LABAs) ⩾30 days before the run-in (7±2 days). Patients were randomised 1:1 to once-daily UMEC 62.5 mcg or placebo (PBO), added to twice-daily open-label ICS/LABA for 12 weeks. Primary end point was trough forced expiratory volume in 1 s (FEV1) at Day 85; secondary end point was weighted mean (WM) 0-6 h FEV1 at Day 84; other end points included COPD Assessment Test (CAT) score and Transition Dyspnoea Index (TDI) score. Adverse events (AEs) were investigated. In the UMEC+ICS/LABA and PBO+ICS/LABA groups, 119 and 117 patients were randomised, respectively. Patients received FP/SAL (40%), BD/FOR (43%) and other ICS/LABAs (17%). UMEC+ICS/LABA resulted in significant improvements in trough FEV1 (Day 85) and in WM 0-6 h FEV1 (Day 84) versus PBO+ICS/LABA (difference: 123 and 148 ml, respectively, both P<0.001). Change from baseline for UMEC+ICS/LABA versus PBO+ICS/LABA was significantly different for CAT score at Day 84 (-1.31, P<0.05), but not for TDI score (0.40, P=0.152). AE incidence was similar with UMEC+ICS/LABA (38%) and PBO+ICS/LABA (42%). UMEC+ICS/LABA improved lung function and CAT score in patients with symptomatic COPD versus PBO+ICS/LABA (ClinicalTrials.gov NCT02257372). PMID:27334739

    Transthyretin (TTR) binds amyloid-β (Aβ) and may reduce brain Aβ, a pathological feature in Alzheimer's disease (AD). N - 3 fatty acids (FA), docosahexaenoic (DHA), and eicosapentaenoic acid (EPA) may increase TTR transcription in rat hippocampus. We studied effects of n - 3 FA supplementation on TTR-levels in patients with AD. Outpatients were randomized to receive 1.7 g DHA and 0.6 g EPA (n - 3/n - 3 group) or placebo (placebo/n - 3 group) during 6 months. After 6 months, all patients received n - 3 FA for another 6 months. TTR and FA were measured in plasma in all subjects, whereas TTR in cerebrospinal fluid (CSF) was measured in a subgroup. The study was completed by 89 patients in the n - 3/n - 3 group (75 y, 57% w) and 85 in the placebo/n - 3 group (75 y, 46% w). Baseline plasma-TTR was within normal range in both groups. After 6 months, plasma-TTR decreased in the placebo/n - 3 group (p < 0.001 within and p < 0.015 between the groups). No changes were observed in CSF TTR. From 6 to 12 months when both groups were supplemented, plasma-TTR increased significantly in both groups. Repeated measures ANOVA indicated an increase in TTR over time (p = 0.04) in those receiving n - 3 FA for 12 months. By linear regression analyses, n - 3 FA treatment was independently associated with increased plasma-TTR at 6 months (β = -0.172, p = 0.028). Thus, n - 3 FA treatment appeared to increase plasma-TTR in patients with AD. Since TTR may influence Aβ deposition in the brain, the results warrant further exploration. PMID:23563245

    To evaluate whether probands from a clinical sample diagnosed as having DSM-III schizotypal and/or paranoid personality disorder have a familial relationship to the schizophrenia-related disorders, the morbid risk for schizophrenia-related disorders and other psychiatric disorders were evaluated in the first-degree relatives of patients with schizotypal and/or paranoid personality disorder and compared with the corresponding risk for these disorders in the first-degree relatives of patients with other non-schizophrenia-related personality disorders. The morbid risk for all schizophrenia-related disorders, and specifically for schizophrenia-related personality disorders, was significantly greater among the relatives of the probands with schizotypal and/or paranoid personality disorder than among the relatives of probands with other personality disorder. The morbid risk for other psychiatric disorders did not differ significantly between the first-degree relatives of the schizotypal/paranoid personality disorder and the other personality disorder control proband samples. These results suggest a specific familial association between schizophrenia-related disorders, particularly schizophrenia-related personality disorders, and clinically diagnosed schizotypal patients.

    Systematic observations of wind speed and direction have been collected at Skagen Fyr (Skagen Lighthouse), northern Denmark from December 1860 to August 2012. Wind speed and wind direction are analyzed based on two data sets given in Beaufort and m/s respectively and based on these data storminess variation is analyzed. Changes in wind climate during this time interval cover the final phase of the relatively cold Little Ice Age and the following warming since the late 19th century. Since the end of the Little Ice Age the wind pattern has clearly changed in terms of both strength and direction. Between 1860 and 1875 storminess (wind events exceeding Beaufort 8) is extremely high, but since then storminess decreases. Around 1870 the annual drift potential (DP) is also extremely high and reaches up to 9600 vector units (VU); since 1980 DP levels are below 3000 VU and decreasing. Resultant drift direction (RDD) is towards the east or east-north-east until about 1960 when it steadily becomes more and more northerly. Most storms occur during autumn and early winter. Summers are less stormy but characterized by unidirectional winds. Since the end of the Little Ice Age most inland parabolic dunes on Skagen Odde have undergone a general stabilization. This shift in dune dynamics is primarily related to continued dune management, but the change in wind climate including an overall decrease in storminess (including a marked decrease in summer storminess) and an increase in southerly and south-westerly winds probably contribute to dune stabilization.

    The present research paper aims at assessing the effectiveness of a psychoeducational intervention in relatives' groups of patients with schizophrenia or schizoaffective disorder. It examines the possible influence of the intervention on family members as well as on the course of the patient illness. Of a total of 131 relatives, 83 consisted the experimental group and 48 the control group. The relatives of the experimental group were divided into 5 groups and attended 18 psychoeducational sessions. Their patients as well s the patients and the relatives of the control group attended no specific intervention and continued their routine care. The psychoeducational intervention included education about the illness, communication skills training and training in problem-solving. It combined educational and psychotherapeutic techniques. The psychometric tools administered were: The Family Burden Scale, The Family Rituals Scale, The General Health Questionnaire GHQ-28, the Center for Epidemiological studies - Depression Scale (CES-D), the Opinions about Mental Illness Scale OMI, two scales concerning the knowledge about the illness, two questionnaires concerning expectations and feedback about the group process and questionnaires regarding sociodemographic characteristics of the sample and information about the illness. The number of hospitalizations of patients (n=91) during the research year was investigated. An interaction between group and measurement was found. While patient hospitalizations of both research groups did not differ significantly at the year before the study with X2=0.54, p=0.46), they differed when measured a year after the intervention, where patients in the intervention group had statistically significant fewer hospitalizations compared to the patients in the control group (x2=4.58, significant at p=0.032). As to the "compliance" in the medication, two statistical tests were conducted, taking into consideration that "compliance" by patients starting

    We calculate the total cross section for the scattering of a quark-anti-quark dipole on a large nucleus at high energy for a strongly coupled N = 4 super Yang-Mills theory using AdS/CFT correspondence. We model the nucleus by a metric of a shock wave in AdS{sub 5}. We then calculate the expectation value of the Wilson loop (the dipole) by finding the extrema of the Nambu-Goto action for an open string attached to the quark and antiquark lines of the loop in the background of an AdS{sub 5} shock wave. We find two physically meaningful extremal string configurations. For both solutions we obtain the forward scattering amplitude N for the quark dipole-nucleus scattering. We study the onset of unitarity with increasing center-of-mass energy and transverse size of the dipole: we observe that for both solutions the saturation scale Q{sub s} is independent of energy/Bjorken-x and depends on the atomic number of the nucleus as Q{sub s}{approx}A{sup 1/3}. Finally we observe that while one of the solutions we found corresponds to the pomeron intercept of {alpha}{sub P} = 2 found earlier in the literature, when extended to higher energy or larger dipole sizes it violates the black disk limit. The other solution we found respects the black disk limit and yields the pomeron intercept of {alpha}{sub P} = 1.5. We thus conjecture that the right pomeron intercept in gauge theories at strong coupling may be {alpha}{sub P} = 1.5.

    Introduction: The relatively frequent systemic comorbidities of geriatric patients can be linked to salivary changes, which may induce oral alteration and discomfort with the removable prosthesis. The aim of the study was to evaluate the salivary parameters in completely edentulous patients treated by removable prosthesis, in relation to their general health status. Material and method: A cross-sectional study was performed on 30 completely edentulous patients, 53% male and 47% female, aged between 53 and 84. The evaluation of the salivary parameters (oral hydration index, pH and salivary flow, viscosity and saliva buffer capacity) was performed with the Saliva Check Buffer kit (GC Corporation). Results: The salivary changes encountered were the following: low hydration level (63%), high saliva viscosity (57%), below-average pH (27%), reduced salivary flow (77%) and low saliva buffer capacity (80%). A reduced salivary flow and saliva buffer capacity was found in women. A lower buffer capacity of the saliva was found in patients with respiratory and gastro-intestinal disease. Conclusions: The alterations of the salivary flow are relatively frequent in geriatric patients, removable denture wearers, with compromised systemic status. These changes may be a risk factor for denture stomatitis and oral candidiasis, with a negative effect on the patient’s comfort and quality of life. PMID:25713626

    Combinations of drugs with distinct and complementary mechanisms of action may offer improved efficacy in the treatment of chronic obstructive pulmonary disease (COPD). In two 12-week, double-blind, parallel-group studies, patients with COPD were randomized 1:1:1 to once-daily umeclidinium (UMEC; 62.5 μg and 125 μg) or placebo (PBO), added to twice-daily fluticasone propionate/salmeterol (FP/SAL; 250/50 μg). In both studies, the primary efficacy measure was trough forced expiratory volume in 1 second (FEV1) at Day 85. Secondary endpoints were weighted-mean (WM) FEV1 over 0-6 hours post-dose (Day 84) and rescue albuterol use. Health-related quality of life outcomes (St. George's Respiratory Questionnaire [SGRQ] and COPD assessment test [CAT]) were also examined. Safety was assessed throughout. Both UMEC+FP/SAL doses provided statistically significant improvements in trough FEV1 (Day 85: 0.127-0.148 L) versus PBO+FP/SAL. Similarly, both UMEC+FP/SAL doses provided statistically-significant improvements in 0-6 hours post-dose WM FEV1 versus PBO+FP/SAL (Day 84: 0.144-0.165 L). Rescue use over Weeks 1-12 decreased with UMEC+FP/SAL in both studies versus PBO+FP/SAL (Study 1, 0.3 puffs/day [both doses]; Study 2, 0.5 puffs/day [UMEC 125+FP/SAL]). Decreases from baseline in CAT score were generally larger for both doses of UMEC+FP/SAL versus PBO+FP/SAL (except for Day 84 Study 2). In Study 1, no differences in SGRQ score were observed between UMEC+FP/SAL and PBO+FP/SAL; however, in Study 2, statistically significant improvements were observed with UMEC 62.5+FP/SAL (Day 28) and UMEC 125+FP/SAL (Days 28 and 84) versus PBO+FP/SAL. The incidence of on-treatment adverse events across all treatment groups was 37-41% in Study 1 and 36-38% in Study 2. Overall, these data indicate that the combination of UMEC+FP/SAL can provide additional benefits over FP/SAL alone in patients with COPD. PMID:26451734

    Background and Purpose To examine the neurophysiological basis for the pronounced differences in hyperactivity and impulsiveness that distinguish the Predominantly Inattentive type of Attention-Deficit/Hyperactivity Disorder (ADHD-PI) from the combined type of the disorder (ADHD-C). Methods Event-related brain responses to a go/no-go test of inhibitory control were measured with functional magnetic resonance imaging (fMRI) in 11 children with ADHD-C and nine children with ADHD-PI, aged 7 to 13 years, who were matched for age, sex, and intelligence. Results There were no significant group differences in task performance. Children with ADHD-C and ADHD-PI activated overlapping regions of right inferior frontal gyrus, right superior temporal lobe, and left inferior parietal lobe during inhibitory control. However, the magnitude of the activation in the temporal and parietal regions, as well as in the bilateral middle frontal gyrus, was greater in children with ADHD-PI than those with ADHD-C. Conversely, children with ADHD-C activated bilateral medial occipital lobe to a greater extent than children with ADHD-PI. Conclusions The results provide preliminary evidence that phenotypic differences between the ADHD-C and ADHD-PI subtypes are associated with differential activation of regions that have previously been implicated in the pathophysiology of ADHD and are thought to mediate executive and attentional processes.

    Patients undergoing bone marrow transplant, using spinal cord services, and with traumatic brain injury represent a relatively new patient type, requiring both intense care and long-term care in the same facility. As medical advances allow these patients the opportunity to recover from their critical illnesses or injuries, designers and caregivers must give increased attention to the long-term critical care environment. Designing for this type of care requires an understanding of new technologies and the potential for the built environment to address the wide range of physical, sensory, and psychological issues long-term inpatients face. Recent work by SmithGroupJJR has provided valuable insights into the ways in which lighting, patient room and unit layouts, spatial volumes, and other design elements can contribute to the recovery of patients who must spend weeks or months in a critical care environment. This knowledge was gained through an approach that allows design professionals to immerse themselves in a health care institution's values, culture, and work processes. By mapping both operational flow and patients' experiences, project teams can develop design solutions that sustain the well-being of higher-acuity patients and their family members and caregivers.

    AIM--To analyse the pathogenic mechanism of HIV related thrombocytopenia. METHODS--Forty one patients with thrombocytopenia and HIV-1 infection were investigated over two years. Anticardiolipin antibodies were measured using an enzyme linked immunosorbent assay and antiplatelet antibodies were measured using an immunocapture technique. Tests for VDRL, C3 and C4, antinuclear antibodies and rheumatoid factor were also carried out in all patients and 80 control subjects (HIV-1 positive but non-thrombocytopenic). Indiumoxine labelled platelets were transfused in 13 patients. P24 antigen were also measured in 12 bone marrow aspirates. RESULTS--Antiplatelet antibodies and circulating immune complexes were found exclusively in the thrombocytopenic group; values for antiplatelet antibodies and circulating immune complexes were both higher in homosexual and bisexual patients. Three kinds of pattern were observed using 111 In-labelled platelets: splenic (n = 10); hepatic (n = 2); and destruction of bone marrow in just one case. The two most influential factors in the sequestration pattern were antiplatelet antibodies in the splenic uptake and circulating immune complexes in the hepatic and marrow sequestration. All patients, except three, had decreased platelet recovery. In those patients with a CD4 lymphocyte count of less than 200 x 10(6) cells/l the recovery was clearly greater (53%) than in patients who had more than 200 x 10(6) /l (28%). Finally, in seven of the 12 patients who were chosen for immunohistochemical study, p24 antigen was detected in the megakaryocytes, verifying that HIV-1 infects such cells. CONCLUSIONS--The pathogenic mechanism of HIV related thrombocytopenia is probably multifaceted. Antiplatelet antibodies and circulating immune complexes would cause peripheral destruction in the spleen, liver, and bone marrow, in that order; and, on the other hand, there would be an ineffective immune thrombopoiesis and direct infection of the megakaryocytes which

    Introduction. The overall incidence and odds of fatal adverse events (FAEs) after exposure to everolimus are not well defined. We performed a comprehensive meta-analysis of published randomized controlled trials (RCTs) to determine the role of everolimus in treatment-related mortality in patients with cancer. Methods. PubMed databases and abstracts from the proceedings of the American Society of Clinical Oncology and the San Antonio Breast Cancer Symposium were searched for RCTs of everolimus either alone or in combination with another agent compared with the control arm without everolimus and that reported deaths from an adverse event from January 1966 to July 2013. The primary objective was to determine the difference of FAEs between everolimus-treated patients and control group patients. Results. In total, 2,997 patients with multiple solid tumors from nine RCTs were included. The overall incidence of FAEs in cancer patients treated with everolimus was 0.7% (95% CI 0.3%–1.1%) compared with 0.4% (95% CI 0.0%–0.7%) in cancer patients who did not receive everolimus. The odds ratio of FAEs was greater in everolimus-treated patients (Peto odds ratio = 3.80, 95% CI 1.59–9.07, p = .003). In subgroup analyses, no significant difference was found in the incidence or odds of FAEs by everolimus administration (alone or in combination) or tumor type (breast cancer vs. nonbreast cancer; p = .63). Conclusion. In patients with cancer, everolimus is associated with a small but significant increase in the odds of a treatment-related fatal events. PMID:24794158

    Epidemiologic studies consistently report associations between obesity and dietary fat but not total energy intake. We measured ad libitum food intake in a laboratory setting and evaluated its relation to body weight and composition, energy expenditure, and macronutrient utilization in 28 women of Pima-Papago heritage (aged 27 +/- 7 y, 85.3 +/- 19.0 kg, 44 +/- 6% body fat; means +/- SD). All women were studied during the follicular phase of the menstrual cycle. After a 4-d weight-maintenance period, the volunteers selected their food for 5 d from computerized vending machines offering a variety of familiar and preferred foods, ie, a "cafeteria diet". Twenty-four-hour energy expenditure and substrate oxidation were measured in a respiratory chamber on the 4th d o weight maintenance and the 5th d of ad libitum intake. Average ad libitum intake was 13,732 +/- 4238 kJ/d (11 +/- 1% protein, 40 +/- 1% fat, 49 +/- 4% carbohydrate), ie, moderate overeating by 27 +/- 37% above weight maintenance requirements (range: -27% to 124%). Percent body fat correlated with daily energy intake (r = 0.53, P < 0.01), the degree of overeating (r = 0.41, P < 0.05), and the selection of a diet higher in fat and lower in carbohydrate (r = 0.70 and r = -0.63, respectively, P < 0.001). Excess carbohydrate intake caused an increase in carbohydrate oxidation (r = 0.51, P < 0.01), whereas excess fat intake resulted in a decrease in fat oxidation (r = -0.53, P < 0.01) and thus a positive fat balance of 85 +/- 65 g/d. The positive relations among degrees of obesity, dietary fat intake and overeating, and the fact that dietary fat does not induce fat oxidation, support the hypothesis that dietary fat promotes obesity in women.

    We determine the all-loop dressing phases of the AdS3/CFT2 integrable system related to type IIB string theory on AdS3×S3×T4 by solving the recently found crossing relations and studying their singularity structure. The two resulting phases present a novel structure with respect to the ones appearing in AdS5/CFT4 and AdS4/CFT3. In the strongly coupled regime, their leading order reduces to the universal Arutyunov-Frolov-Staudacher phase as expected. We also compute their subleading order and compare it with recent one-loop perturbative results and comment on their weak-coupling expansion.

  16. Effectiveness of an intercultural module added to the treatment guidelines for Moroccan and Turkish patients with depressive and anxiety disorders

    2011-01-01

    Background Since the sixties of the last century, many people from Morocco and Turkey have migrated into the Netherlands. In the last decade, Moroccan and Turkish patients have found their way to organizations for mental health care. However, they often drop out of treatment. Problems in the communication with therapists and different expectations regarding treatment seem to be causal factors for the early drop-out of therapy. In the Netherlands as in other countries courses have been developed for training cultural competence of therapists. Yet, up to now, the effectiveness of increased cultural competence of therapists in reducing drop-out of treatment has not been studied. Methods/Design A randomized clinical trial was started in January 2010. Moroccan and Turkish adult patients who are referred to our outpatient clinics for mood and anxiety disorders are randomly assigned to mental health workers who are trained in a cultural module and to those who are not. The therapists have been trained in the Cultural Formulation and in techniques bridging the (cultural) gap between them and their Moroccan and Turkish patients. The target number of participants is 150 patients, 75 for each group. Drop-out of treatment is the primary outcome measure. Secondary outcome measures are no-show and patients' perspective of care. Discussion The study will give an answer to the question whether increasing cultural competence of therapists reduces drop-out of treatment in Moroccan and Turkish outpatients with depressive and anxiety disorders.

    Pain is a personal experience and patient-provider communication therefore an essential part of diagnosis and treatment where the patient's perspective needs to be central. The aim of this descriptive cross-sectional study was to investigate chronic-pain-related patient-provider communication in the context of sociodemographic variables, pain variables, perceived outcome of care, and satisfaction with health care providers. A postal questionnaire measuring socio-demographic variables, pain characteristics, pain-related health care utilization and patient-provider communication was sent to a sample of 4,500 individuals randomly drawn from the national population of Iceland. A subsample reporting chronic pain and having visited a health care provider for pain the previous six months (n = 401) was analyzed. Relationships between patient-provider communication and other measured variables were tested using bivariate and multivariate statistics. The more chronic pain impaired health-related quality of life, the more provider control the patients perceived in the patient-provider communication. There was also a strong negative relationship between patients' perception of providers' support and openness to discussing symptoms, and satisfaction with health care provider. Patients' perception of their own control in patient-provider communication and involvement in decisions regarding care was related to sociodemographic variables (specifically, education and residence) but not to pain related variables. This study highlights the importance of assessing chronic pain in a broad spectrum, listening, and giving patients time and support to communicate chronic pain and how it affects their life situation. The more interfering the pain is, the more important this is. PMID:27553131

    Despite advances in pain management, critically ill patients continue to have unacceptably high rates of uncontrolled pain. Using the Behavioural Pain Scale and physiological indicators of pain, this study examines pain levels in mechanically ventilated patients prior to and during routine nursing procedures. A prospective descriptive design was used to assess and describe care-related pain associated with nociceptive procedures (repositioning, endotracheal suctioning, and vascular punctures) and non-nociceptive procedures (mouth care, eye care and dressing change). A sample of 247 mechanically ventilated Jordanian patients was recruited from intensive care units in a military hospital. The overall mean procedural pain score of 6.34 (standard deviation [SD] 2.36) was significantly higher than the mean preprocedural pain score of 3.43 (SD 0.67, t[246]=20.82, P<0.001). The highest mean procedural pain scores were observed during repositioning (9.25, SD 1.29). Few patients received analgesics and/or sedatives in the hour prior to the procedures. The mean Ramsay Scale score was 2.49 (SD 0.95), indicating that patients were either anxious or responsive to command only. The mean physiological indicators of pain increased during repositioning and endotracheal suctioning and decreased during the rest of the procedures. Mechanically ventilated patients experience pain prior to and during routine nursing procedures. Harmless and comfort procedures are actually painful. When caring for nonverbal critically ill patients, clinicians need to consider care-related pain associated with their interventions. Relying on changes in vital signs as a primary indicator of pain can be misleading. PMID:27456175

    It is not uncommon for patients who are receiving antipsychotic medication to be given anticholinergic agents, such as biperiden, despite the relative absence of neurological side-effects. Two cases of schizophrenia are reported in which insomnia developed after biperiden withdrawal or reduction. The insomnia continued until biperiden treatment was reinstated, despite the fact that the patients did not exhibit signs or report symptoms indicative of antipsychotic drug-induced neurological side-effects. The occurrence of insomnia following the withdrawal of biperiden or reduction in the dose has not been previously reported. One potential explanation for the insomnia is cholinergic rebound following the withdrawal of biperiden.

    Background D2 lymphadenectomy has been increasingly regarded as standard surgical procedure for advanced gastric cancer (GC), while the necessity of No.14v lymph node (14v) dissection for distal GC is still controversial. Methods A total of 920 distal GC patients receiving at least a D2 lymph node dissection in Department of Gastric Cancer, Tianjin Medical University Cancer Institute and Hospital were enrolled in this study, of whom, 243 patients also had the 14v dissected. Other 677 patients without 14v dissection were used for comparison. Results Forty-five (18.5%) patients had 14v metastasis. There was no significant difference in 3-year overall survival (OS) rate between patients with and without 14v dissection. Following stratified analysis, in TNM stages I, II, IIIa and IV, 14v dissection did not affect 3-year OS; in contrast, patients with 14v dissection had a significant higher 3-year OS than those without in TNM stages IIIb and IIIc. In multivariate analysis, 14v dissection was found to be an independent prognostic factor for GC patients with TNM stage IIIb/IIIc disease [hazard ratio (HR), 1.568; 95% confidence interval (CI): 1.186-2.072; P=0.002]. GC patients with 14v dissection had a significant lower locoregional, especially lymph node, recurrence rate than those without 14v dissection (11.7% vs. 21.1%, P=0.035). Conclusions Adding 14v to D2 lymphadenectomy may be associated with improved 3-year OS for distal GC staged TNM IIIb/IIIc. PMID:26752932

    1. Ketanserin or slow-release nifedipine were added to the treatment of 24 patients with hypertension uncontrolled by a thiazide diuretic plus beta-adrenoceptor antagonist in an observer-blind, randomised parallel-group study of 6 months duration. 2. At 6 months the mean falls in supine blood pressure were for ketanserin (mean daily dose 77 mg) 7/5 mm Hg and for nifedipine (mean daily dose 62 mg) 27/10 mm Hg. The difference between the treatments was significant for systolic blood pressure (P less than 0.02) and mean arterial pressure (P less than 0.05). Six nifedipine-treated patients reached target blood pressure, compared with one patient with ketanserin (P less than 0.02). 3. One patient taking nifedipine, and none taking ketanserin withdrew because of side-effects. The tolerability of the two drugs was broadly similar. 4. Ketanserin treatment was associated with significant changes in supine pulse rate (-8 beats min-1, P less than 0.05) and corrected QT interval (+27 ms, P less than 0.05). Nifedipine treatment had no effect on these variables. The change in pulse rate was significantly different between the groups. 5. In patients treated with a diuretic and beta-adrenoceptor blocker who required additional treatment ketanserin was significantly inferior to nifedipine. PMID:2893636

    Standard markers in cerebrospinal fluid (CSF), as soluble amyloid beta 1-42 (Abeta1-42) and total tau protein (t-tau), may contribute to dementia subtypes diagnostic accuracy. Yet, their sensitivity to assess the different degree of cognitive deficit is not fully clarified. Our study analyses Abeta1-42 and t-tau CSF levels in different cohorts of Alzheimer's disease (AD) patients, distinguished as early AD (mild cognitively impaired subjects recently converted to AD), mild AD (MMSE<23; > or =18), and moderately advanced AD (MMSE<18). The control group was represented by age-matched patients affected by depressive pseudo-dementia. Reduced Abeta1-42 and increased t-tau CSF levels were confirmed as hallmarks of AD at any disease stage. In early AD patients, Abeta1-42 levels were already significantly low, if compared to the control group (336 vs 867 ng/L; p<0.0001). On the contrary, Abeta1-42 levels did not differ between AD subgroups, and in particular between mild to moderate AD. A significant progressive increase of t-tau concentration was found when comparing early AD (269 ng/L) to more advanced AD stages (468 ng/L and 495 ng/L for mild and moderate AD, respectively). Our findings confirm that the impairment of amyloidogenic cascade is an early, even pre-clinical process, but suggest that soluble Abeta1-42 concentration has a negligible correlation with the clinical progression. Conversely, t-tau concentration correlates with the transition towards marked cognitive impairment.

    Breakfast omission is associated with obesity and CVD/diabetes, but the acute effects of extended morning fasting upon subsequent energy intake and metabolic/hormonal responses have received less attention. In a randomised cross-over design, thirty-five lean men (n 14) and women (n 21) extended their overnight fast or ingested a typical carbohydrate-rich breakfast in quantities relative to RMR (i.e. 1963 (sd 238) kJ), before an ad libitum lunch 3 h later. Blood samples were obtained hourly throughout the day until 3 h post-lunch, with subjective appetite measures assessed. Lunch intake was greater following extended fasting (640 (sd 1042) kJ, P< 0.01) but incompletely compensated for the omitted breakfast, with total intake lower than the breakfast trial (3887 (sd 1326) v. 5213 (sd 1590) kJ, P< 0.001). Systemic concentrations of peptide tyrosine-tyrosine and leptin were greater during the afternoon following breakfast (both P< 0.05) but neither acylated/total ghrelin concentrations were suppressed by the ad libitum lunch in the breakfast trial, remaining greater than the morning fasting trial throughout the afternoon (all P< 0.05). Insulin concentrations were greater during the afternoon in the morning fasting trial (all P< 0.01). There were no differences between trials in subjective appetite during the afternoon. In conclusion, morning fasting caused incomplete energy compensation at an ad libitum lunch. Breakfast increased some anorectic hormones during the afternoon but paradoxically abolished ghrelin suppression by the second meal. Extending morning fasting until lunch altered subsequent metabolic and hormonal responses but without greater appetite during the afternoon. The present study clarifies the impact of acute breakfast omission and adds novel insights into second-meal metabolism. PMID:26004166

    The effects of twice-daily GLP-1 analogue injections added on continuous subcutaneous insulin infusion (CSII) in patients with poorly controlled type 2 diabetes (T2DM) were unknown. After optimization of blood glucose in the first 3 days by CSII during hospitalization, patients with poorly controlled T2DM were randomized to receive CSII combined with injections of exenatide or placebo for another 3 days. A total of 51 patients (30 in exenatide and 21 in placebo groups) with mean A1C 11% were studied. There was no difference in mean glucose but a significant higher standard deviation of plasma glucose (SDPG) was found in the exenatide group (50.51 ± 2.43 vs. 41.49 ± 3.00 mg/dl, p = 0.027). The improvement of incremental area under the curve (AUC) of glucose and insulinogenic index (Insulin0–peak/ Glucose0–peak) in 75 g oral glucose tolerance test was prominent in the exenatide group (p < 0.01). The adiponectin level was significantly increased with exenatide added on (0.39 ± 0.32 vs. −1.62 ± 0.97 μg/mL, in exenatide and placebo groups, respectively, p = 0.045). In conclusion, the add-on of GLP-1 analogue to CSII increased glucose variability and the β - cell response in patients with poorly controlled T2DM. PMID:26607841

    The French Chronic Myeloid Leukemia Study Group prospective randomized study results indicate that the addition of cytarabine to alpha interferon (IFN-alpha) increases the rate of major cytogenetic response and prolongs survival in patients with early chronic phase chronic myelogenous leukemia (CML). The French group study design permitted a single crossover to include or discontinue cytarabine or interferon. Endpoints were overall survival, complete hematologic remission (CHR) at six months, and major cytogenetic response at 12 months. We modified a published Markov model that compared IFN-alpha alone to IFN-alpha plus cytarabine and included the possibility of crossover as in the French study. The model permits allogeneic and autologous stem cell transplantation (SCT), and follows cytogenetic response and acceleration of CML through death. Treatment response, toxicity, and survival are drawn from the French Chronic Myeloid Leukemia Study Group population of 810 patients on an intention-to-treat model. Survivals are extended to 62 months based on currently available follow-up. Costs from a United States oncology specialty institution, and state utilities from previous research and a quality-adjusted Time Without Symptoms or Toxicity analysis of the subject study were discounted at 3% per annum. At the median cohort age of 50, cytarabine offers 21 months of added median survival to IFN-alpha, which itself is superior to conventional chemotherapy by 21 months. Cost-effectiveness estimates for cytarabine added to IFN-alpha range from $7,000 per quality-adjusted life year (QALY) to $35,000 per QALY, under all plausible assumptions superior to IFN-alpha alone. The model is sensitive to the quality of life on therapy, as well as to remission rate with additive cytarabine, although the cost-effectiveness calculations are robust over the entire range of clinical assumptions. Based on data from the French study, cytarabine added to IFN-alpha substantially improves the cost

    Background and aims. Diabetic patients display an increased risk of oral disorders, and oral health related quality of life (OHRQL) might affect their management and treatment modalities. The aim of the present study was to determine OHRQL and associated parameters in patients with diabetes. Materials and methods. In this study two hundred patients were recruited from the diabetes clinic in Mustafa Khomeini Hospital in Tehran, Iran. OHRQL was assessed using Oral Health Impact Profile Questionnaire (OHIP-20). Also, another questionnaire was designed which contained questions regarding participants' knowledge about oral complications of diabetes and oral health behavior. OHRQL was categorized as low and good. Data were analyzed using logistic regression at P = 0.05. Results. Of the diabetic patients assessed, 77.5% were in good and 22.5% were in low categories of OHRQL. This quality was significantly associated with age (OR = 4.03, 95% CI = 1.63-11.29), knowledge about diabetes oral complications (OR = 18.17 95% CI = 4.42-158.6), educational level (OR = 26.31 95% CI = 4.2-1080.3), referred for dental visit by physician (OR = 3.16 95% CI = 1.48-6.69), frequency of brushing (OR = 10.29 95% CI = 3.96-31.2) and length of time diagnosed with diabetes (OR = 6.21 95% CI = 2.86-13.63). Conclusion. Oral health related quality of life was not negatively affected by diabetes mellitus in the assessed sample. PMID:25587385

  10. Neuroprotective effect of novel cognitive enhancer noopept on AD-related cellular model involves the attenuation of apoptosis and tau hyperphosphorylation

    2014-01-01

    Background Noopept (N-phenyl-acetyl-L-prolylglycine ethyl ester) was constructed as a dipeptide analog of the standard cognition enhancer, piracetam. Our previous experiments have demonstrated the cognition restoring effect of noopept in several animal models of Alzheimer disease (AD). Noopept was also shown to prevent ionic disbalance, excitotoxicity, free radicals and pro-inflammatory cytokines accumulation, and neurotrophine deficit typical for different kinds of brain damages, including AD. In this study, we investigated the neuroprotective action of noopept on cellular model of AD, Aβ25–35-induced toxicity in PC12 cells and revealed the underlying mechanisms. Results The neuroprotective effect of noopept (added to the medium at 10 μM concentration, 72 hours before Аβ25–35) was studied on Аβ25–35-induced injury (5 μM for 24 h) in PC12 cells. The ability of drug to protect the impairments of cell viability, calcium homeostasis, ROS level, mitochondrial function, tau phosphorylation and neurite outgrowth caused by Аβ25–35 were evaluated. Following the exposure of PC12 cells to Аβ25–35 an increase of the level of ROS, intracellular calcium, and tau phosphorylation at Ser396 were observed; these changes were accompanied by a decrease in cell viability and an increase of apoptosis. Noopept treatment before the amyloid-beta exposure improved PC12 cells viability, reduced the number of early and late apoptotic cells, the levels of intracellular reactive oxygen species and calcium and enhanced the mitochondrial membrane potential. In addition, pretreatment of PC12 cell with noopept significantly attenuated tau hyperphosphorylation at Ser396 and ameliorated the alterations of neurite outgrowth evoked by Аβ25–35. Conclusions Taken together, these data provide evidence that novel cognitive enhancer noopept protects PC12 cell against deleterious actions of Aβ through inhibiting the oxidative damage and calcium overload as well as suppressing

    Neurocognitive deficits in schizophrenia (SZ) are thought to be stable trait markers that predate the illness and manifest in relatives of patients. Adolescence is the age of maximum vulnerability to the onset of SZ and may be an opportune “window” to observe neurocognitive impairments close to but prior to the onset of psychosis. We reviewed the extant studies assessing neurocognitive deficits in young relatives at high risk (HR) for SZ and their relation to brain structural alterations. We also provide some additional data pertaining to the relation of these deficits to psychopathology and brain structural alterations from the Pittsburgh Risk Evaluation Program (PREP). Cognitive deficits are noted in the HR population, which are more severe in first-degree relatives compared to second-degree relatives and primarily involve psychomotor speed, memory, attention, reasoning, and social-cognition. Reduced general intelligence is also noted, although its relationship to these specific domains is underexplored. Premorbid cognitive deficits may be related to brain structural and functional abnormalities, underlining the neurobiological basis of this illness. Cognitive impairments might predict later emergence of psychopathology in at-risk subjects and may be targets of early remediation and preventive strategies. Although evidence for neurocognitive deficits in young relatives abounds, further studies on their structural underpinnings and on their candidate status as endophenotypes are needed. PMID:20300465

    2013-01-01

    Background If one party has more or better information than the other, an information asymmetry can be assumed. The aim of the study was to identify the origin of incomplete patient-related preoperative information, which led to disruptions and losses of time during pre-anaesthetic patient briefing. We hypothesized that lower employees’ educational level increases the amount of disruptive factors. Methods A prospective observational study design was used. Patient selection was depending on the current patient flow in the area of the clinic for pre-anesthetic patient briefing. Data were collected over a period of 8 weeks. A stopwatch was used to record the time of disruptive factors. Various causes of time losses were grouped to facilitate statistical evaluation, which was performed by using the U-test of Mann and Whitney, Chi-square test or the Welch-t-test, as required. Results Out of 221 patients, 130 patient briefings (58.8%) had been disrupted. Residents were affected more often than consultants (66% vs. 47%, p = 0.008). Duration of disruptions was independent of the level of training and lasted about 2,5 minutes and 10% of the total time of patient briefing. Most time-consuming disruptive factors were missing study results, incomplete case histories, and limited patient compliance. Conclusions Disruptions during pre-anesthetic patient briefings that were caused by patient-related information asymmetry are common and account for a significant loss of time. The resultant costs justify investments in appropriate personnel allocation. PMID:24090129

    OBJECTIVE To test cognitive behavioral therapy for adherence and depression (CBT-AD) in type 2 diabetes. We hypothesized that CBT-AD would improve adherence; depression; and, secondarily, hemoglobin A1c (A1C). RESEARCH DESIGN AND METHODS Eighty-seven adults with unipolar depression and uncontrolled type 2 diabetes received enhanced treatment as usual (ETAU), including medication adherence, self-monitoring of blood glucose (SMBG), and lifestyle counseling; a provider letter documented psychiatric diagnoses. Those randomized to the intervention arm also received 9–11 sessions of CBT-AD. RESULTS Immediately after acute treatment (4 months), adjusting for baseline, CBT-AD had 20.7 percentage points greater oral medication adherence on electronic pill cap (95% CI −31.14 to −10.22, P = 0.000); 30.2 percentage points greater SMBG adherence through glucometer downloads (95% CI −42.95 to −17.37, P = 0.000); 6.44 points lower depression scores on the Montgomery-Asberg Depression Rating Scale (95% CI 2.33–10.56, P = 0.002); 0.74 points lower on the Clinical Global Impression (95% CI 0.16–1.32, P = 0.01); and 0.72 units lower A1C (95% CI 0.29–1.15, P = 0.001) relative to ETAU. Analyses of 4-, 8-, and 12-month follow-up time points indicated that CBT-AD maintained 24.3 percentage points higher medication adherence (95% CI −38.2 to −10.3, P = 0.001); 16.9 percentage points greater SMBG adherence (95% CI −33.3 to −0.5, P = 0.043); and 0.63 units lower A1C (95% CI 0.06–1.2, P = 0.03) after acute treatment ended. For depression, there was some evidence of continued improvement posttreatment, but no between-group differences. CONCLUSIONS CBT-AD is an effective intervention for adherence, depression, and glycemic control, with enduring and clinically meaningful benefits for diabetes self-management and glycemic control in adults with type 2 diabetes and depression.

    Liraglutide, a glucagon-like peptide (GLP-1) receptor agonist, has showed favorable effects in the glycaemic control and weight reduction in patients with type 2 diabetes mellitus (T2DM). The meta-analysis was to compare the efficacy and safety of liraglutide added to metformin with other treatments in patients with T2DM. A systematic literature search on PubMed, Embase, Web of Science and the Cochrane library databases were performed. Eligible studies were randomized controlled trials (RCTs) of patients with T2DM who received the combination treatment of liraglutide and metformin. Pooled estimates were performed using a fixed-effects model or random-effects model. A total of nine RCTs met the inclusion criteria. Compared with control (placebo, sitagliptin, glimepiride, dulaglutide, insulin glargine, and NPH), liraglutide in combination with metformin resulted in significant reductions in HbA1c, bodyweight, FPG, and PPG, and similar reductions in SBP, and DBP. Moreover, liraglutide combined with metformin did not increase the risk of hypoglycemia, but induced a higher incidence of gastrointestinal disorders. In conclusion, this meta-analysis confirmed the use of liraglutide as add-on to metformin appeared to be effective and safe for patients with T2DM. However, considering the potential limitations in this study, more large-scale, well-conducted RCTs are needed to identify our findings.

    An increasing demand for genetic testing has moved the procedure from highly selected at-risk individuals, now also including cancer patients for treatment associated testing. The heritable fraction of ovarian cancer is more than 10%, and our department has offered BRCA testing to such patients irrespective of family history since 2002. This study examined potential psychosocial distress associated with this procedure using The Multidimensional Impact of Cancer Risk Assessment (MICRA) questionnaire and other patient-rated generic distress instruments. Patients were divided into four groups according to cancer risk: mutation carriers, own history of breast cancer and ovarian cancer, family history of breast cancer and/or ovarian cancer, and patients without family history. In a postal survey, 354 patients responded. Good acceptance of the MICRA was observed, and previously described good psychometric properties were confirmed. A significant association between MICRA total score and receiving a positive BRCA test result was found. No significant between-group differences were observed with generic distress instruments. Time since cancer diagnosis, test result, and survey showed no significant associations with MICRA scores. Internal consistencies of instruments were adequate. Exploratory and confirmatory factor analyses showed adequate fit indices for a three factor solution of the MICRA, but further refinement of the items should be considered. In conclusion, the specific types of worry and distress most relevant to receiving genetic testing irrespective of family history were not captured by the generic distress instruments. The MICRA was supported as a useful tool for detection of mental distress related to genetic testing and risk evaluation.

    Purpose: Retinal adenosine triphosphate is mainly produced via glycolysis, so inhibition of glycolysis may promote the onset and progression of age-related macular degeneration (AMD). When glycolysis is inhibited, pyruvate is metabolized by lactic acid fermentation instead of entering the mitochondrial tricarboxylic acid (TCA) cycle. We measured urinary pyruvate and lactate levels in patients with AMD. Methods: Eight patients with typical AMD (tAMD group) and 9 patients with polypoidal choroidal vasculopathy (PCV group) were enrolled. Urinary levels of pyruvate, lactate, α-hydroxybutyrate, and β-hydroxybutyrate were measured in all patients. Results: The mean urinary levels of pyruvate and lactate were 8.0 ± 2.8 and 7.5 ± 8.3 μg/mg creatinine (reference values: 0.5-6.6 and 0.0-1.6), respectively, with the mean increase over the reference value being 83.6 ± 51.1% and 426.5 ± 527.8%, respectively. In 12 patients (70.6%), the lactate/pyruvate ratio was above the reference range. Urinary levels of α-hydroxybutyrate and β-hydroxybutyrate were decreased by -31.9 ± 15.2% and -33.1 ± 17.5% compared with the mean reference values. There were no significant differences of any of these glycolysis metabolites between the tAMD and PCV groups. Multivariate analysis revealed that none of the variables tested, including patient background factors (age, hypertension, diabetes, hyperlipidemia, cerebrovascular disease, alcohol, smoking, visual acuity, and AMD phenotype), were significantly associated with the lactate/pyruvate ratio. Conclusion: A high lactate/pyruvate ratio is a well-known marker of mitochondrial impairment, and it indicates poor oxidative function in AMD. Our results suggest that increased lactate levels may be implicated in the pathogenesis of AMD. PMID:25191529

    The influence of experience in categorizing suspect and occult fractures on radiography compared to MRI and clinical outcome has not been studied. The aim of this study is to evaluate the importance of experience in diagnosing normal or suspect hip radiographs compared to MRI. Primarily reported normal or suspect radiography in 254 patients with low-energy hip trauma and subsequent MRI was re-evaluated by two experienced reviewers. Primary readings and review were compared. The prevalence of fractures among normal and suspect radiographic studies was assessed. Clinical outcome was used as reference. At review of radiography, 44 fractures (17 %) were found. Significantly more fractures were found among suspect cases than among normal cases. At MRI, all 44 fractures were confirmed, and further 64 fractures were detected (25 %). MRI detected all fractures with no missed fractures revealed at follow-up. There were a significantly higher proportion of fractures at MRI among the suspect radiographic diagnoses for both the primary report and at review than among occult cases. The more experienced reviewers classified radiography examinations with higher accuracy than primary reporting general radiologists. There was almost complete agreement on MRI diagnoses.

  1. FRAGMATIC: A randomised phase III clinical trial investigating the effect of fragmin® added to standard therapy in patients with lung cancer

    2009-01-01

    Background Venous thromboembolism (VTE) occurs when blood clots in the leg, pelvic or other deep vein (deep vein thrombosis) with or without transport of the thrombus into the pulmonary arterial circulation (pulmonary embolus). VTE is common in patients with cancer and is increased by surgery, chemotherapy, radiotherapy and disease progression. Low molecular weight heparin (LMWH) is routinely used to treat VTE and some evidence suggests that LMWH may also have an anticancer effect, by reduction in the incidence of metastases. The FRAGMATIC trial will assess the effect of adding dalteparin (FRAGMIN), a type of LMWH, to standard treatment for patients with lung cancer. Methods/Design The study design is a randomised multicentre phase III trial comparing standard treatment and standard treatment plus daily LMWH for 24 weeks in patients with lung cancer. Patients eligible for this study must have histopathological or cytological diagnosis of primary bronchial carcinoma (small cell or non-small cell) within 6 weeks of randomisation, be 18 or older, and must be willing and able to self-administer 5000 IU dalteparin by daily subcutaneous injection or have it administered to themselves or by a carer for 24 weeks. A total of 2200 patients will be recruited from all over the UK over a 3 year period and followed up for a minimum of 1 year after randomisation. Patients will be randomised to one of the two treatment groups in a 1:1 ratio, standard treatment or standard treatment plus dalteparin. The primary outcome measure of the trial is overall survival. The secondary outcome measures include venous thrombotic event (VTE) free survival, serious adverse events (SAEs), metastasis-free survival, toxicity, quality of life (QoL), levels of breathlessness, anxiety and depression, cost effectiveness and cost utility.

    HIV-1 genetic subtypes might have a different impact on disease progression and response to antiretroviral therapy (ART). Few data are available on the immune activation profile in patients with different HIV-1 subtypes. We have tested by ELISA the plasma levels of an immune activation marker, soluble CD27 (sCD27), in a cohort of 64 patients infected with HIV-1 subtypes A-D, at baseline and after 1 year of virologically successful ART. Plasma sCD27 was significantly higher in the whole HIV-1-infected population as compared to healthy subjects [522 U/ml (188-1,307) vs. 285 U/ml (174-397), P < 0.001]. Among the four different HIV-1 subtypes, patients with subtype C virus had significantly higher plasma sCD27 [684 U/ml, (188-1228)] as compared to patients with subtype A [428 U/ml (247-1307), P < 0.05] and B [454 (211-925), P < 0.05]. After 1 year of ART, plasma sCD27 significantly decreased in all groups but patients with subtype C viruses had the largest reduction of sCD27 from baseline. The data indicate that a similar immune activation profile is present in patients infected with HIV-1 subtypes A, B, and D and that in presence of successful ART these subtypes respond similarly in terms of immune activation. Intriguingly, subtype C infection seems to be associated with higher levels of plasma sCD27, suggesting that HIV-1 genetic subtype C may have a different impact on disease outcome and response to therapy.

    [Purpose] Gait function after a stroke is an important factor for determining a patient’s ability to independently perform activities of daily living (ADL). The objective of this study was to elucidate the factors associated with gait function in post-stroke patients. [Subjects] Thirty-nine stroke patients (16 females and 23 males; average age 67.82 ± 10.96 years; post-onset duration: 200.18 ± 27.14 days) participated in this study. [Methods] Their gait function, motor function (Manual Muscle Test [MMT] and Brünnstrom stage), level of cognition (Mini-Mental State Examination score [MMSE], and the Loewenstein Occupational Therapy Cognitive Assessment for the Geriatric Population [LOTCA-G]), and ADL (Korean modified Barthel index [K-MBI]) were assessed. [Results] The degree of gait function showed significant positive correlations with the following variables: MMT of the elbow, knee, ankle and wrist; Brünnstrom stage; MMSE; LOTCA-G subscores except motor praxis; K-MBI. Stepwise linear regression analysis revealed the Brünnstrom stage was the only explanatory variable closely associated with gait level. [Conclusion] Gait function of post-stroke patients was related to motor function, cognition, and ADL. In particular, there is a significant association between gait level and the Brünnstrom stages, reflecting the importance of monitoring the motor recovery of gait function in post-stroke patients.

    The presence of amyloid-related serum component, protein ASC, in serum samples from 63 leprosy patients was investigated. Protein ASC was detected in 38% of the patients. A correlation to the disease spectrum of leprosy was apparent: polar lepromatous cases, 64% positive; borderline lepromatous, 50%; borderline tuberculoid, 36%; subpolar tuberculoid, 17%; and polar tuberculoid, negative. Antibody activity against the a antigen of Mycobacterium leprae was also determined, showing a similar correlation to the disease spectrum. Serum samples from 23 apparently healthy Ethiopians serving as controls showed a protein ASC incidence of 22%. This figure is significantly higher than the frequency found by others among healthy Norwegian blood donors. Immunoglobulin M levels among patients were elevated in the borderline lepromatous and poplar lepromatous groups. The three tuberculoid groups did not differ in this respect from the control group but were all elevated as compared to a normal Caucasian serum pool. Although raised immunoglobulin M levels seemed to parallel increased frequencies of protein ASC in the patient groups as well as in controls, this correlation might be only secondary to a primary derangement in T-cell function.

    Amyotrophic Lateral Sclerosis(ALS) patients are unable to successfully communicate their desires, although their mental capacity is the same as non-affected persons. Therefore, the authors put emphasis on Event-Related Potential(ERP) which elicits the highest outcome for the target visual and hearing stimuli. P300 is one component of ERP. It is positive potential that is elicited when the subject focuses attention on stimuli that appears infrequently. In this paper, the authors focused on P200 and N200 components, in addition to P300, for their great improvement in the rate of correct judgment in the target word-specific experiment. Hence the authors propose the algorithm that specifies target words by detecting these three components. Ten healthy subjects and ALS patient underwent the experiment in which a target word out of five words, was specified by this algorithm. The rates of correct judgment in nine of ten healthy subjects were more than 90.0%. The highest rate was 99.7%. The highest rate of ALS patient was 100.0%. Through these results, the authors found the possibility that ALS patients could communicate with surrounding persons by detecting ERP(P200, N200 and P300) as their desire.

    Epstein-Barr virus (EBV)-encoded latent membrane protein 2 (LMP2) promotes nasopharyngeal carcinoma (NPC) progression. Previously, we reported that the dendritic cells (DCs) transfected with EBV-LMP2 recombinant serotype 5 adenoviruses (rAd5) induced anti-tumor effect by eliciting cytotoxic T lymphocytes (CTLs)-mediated immune response in vitro and the adenoviral vaccine of EBV-LMP2 (rAd5-EBV-LMP2) stimulated antigen-specific cellular immunity in mice. However, the safety and immunological effect of rAd5-EBV-LMP2 vaccine in human still remained unknown. Here we conducted a single-center, non-randomized, open-label, single-arm phase I clinical trial to clarify this unsolved issue. A total of 24 patients with regional advanced NPC were sequentially enrolled into three dose level groups (2×10(9), 2×10(10), 2×10(11) vp). The rAd5-EBV-LMP2 vaccines were intramuscularly injected for four times within 28 d (D0, D7, D14, D28). Blood samples were harvested immediately before every vaccination, one week and one month after the last vaccination (D0, D7, D14, D28, D35, D58). All the vaccine inoculation-related toxicities presented as grade I/II adverse events. The most frequent systemic adverse reactions were fatigue (33.0%, 8/24), myalgia (29.2%, 7/24) and cough (29.2%, 7/24), while the most common regional adverse reaction was tenderness in the inoculation site (54.2%, 13/24). In addition, proportion of CD(3+)CD(4+) cells in peripheral blood was significantly increased in the high dose group (2×10(11) vp). The rAd5-EBV-LMP2 vaccine was generally well-tolerated and the high dose (2×10(11) vp) is recommended to be adopted in phase II studies. The long-term outcome of rAd5-EBV-LMP2 vaccine inoculation is required to be determined in following placebo-controlled trials. PMID:27477649

    In our prior work with a young sample (age < 60), we showed that three neuropsychological functions were impaired among relatives of schizophrenic patients: abstraction, verbal memory, and auditory attention. In the present work we show that these results do not generalize to an older sample aged 60 years and greater. Thus, although we and others have put forth measures of neuropsychological function as indicators of the schizophrenia genotype, the present study suggests that conclusions may be limited to non-elderly samples. Further work is needed to address this issue definitively.

    Formal genetic studies suggested a substantial genetic influence for anorexia nervosa (AN), but currently results are inconsistent. The use of the neurocognitive endophenotype approach may facilitate our understanding of the AN pathophysiology. We investigated decision-making, set-shifting and planning in AN patients (n=29) and their unaffected relatives (n=29) compared to healthy probands (n=29) and their relatives (n=29). The Iowa Gambling Task (IGT), the Tower of Hanoi (ToH) and the Wisconsin Card Sorting Test (WCST) were administered. Concordance rates and heritability indices were also calculated in probands/relatives. Impaired performance on the IGT and the WCST were found in both AN probands and their relatives, although planning appeared to be preserved. The IGT heritability index suggested the presence of genetic effects that influence this measure. No evidence for genetic effects was found for the WCST. The results suggest the presence of a shared dysfunctional executive profile in women with AN and their unaffected relatives, characterized by deficient decision-making and set-shifting. Concordance analysis strongly suggests that these impairments aggregate in AN families, supporting the hypothesis that they may constitute biological markers for AN. Decision-making impairment presents a moderate heritability, suggesting that decision-making may be a candidate endophenotype for AN. PMID:23122554

    There are many areas of common interest between anti-doping laboratories and those working in the clinical, legal and forensic fields. In addition to methodological similarities, there are aspects of the findings in sport drug testing that overlap with other fields in such a way that sport drug testing and clinical, legal or forensic work may benefit from mutual interaction. Three recent examples are presented from the author's experience. Case report 1 concerns the clinical relevance of hCG findings in sport drug testing as potential indicators of the presence of a (testicular) tumour in athletes. Case report 2 refers to difficulties that accredited laboratories can encounter due to differences between national legal systems and the administrative regulation systems of sport authorities. The example involves a network of blood collection for further autologous transfusion. Case report 3 relates to additional forensic-type investigations needed to interpret a situation where intoxication of a whole delegation was responsible for apparent doping cases. Clinical, legal and forensic fields must recognize the added value that some results and developments coming from anti-doping laboratories may have. At the same time anti-doping analysts should be aware of new issues, methodologies and problems appearing in related fields.

    Objective Ankylosing spondylitis (AS) is a chronic inflammatory disease of the spine and sacroiliac joints of unknown etiology. Recent studies have reported increased oxidative stress, which is implicated in the pathogenesis of a number of diseases, in AS. The purpose of this study was to investigate oxidative stress and related factors in AS. Material and Methods Eighty-five patients with AS [36 (16–64) years; 65 male/20 female] and 56 healthy subjects [36 (21–63) years; 39 male/17 female] with no known cardiovascular risk factors were enrolled. Serum total oxidant status (TOS) and total anti-oxidant status (TAS) were studied. The Bath ankylosing spondylitis functional index (BASFI), Bath ankylosing spondylitis disease activity index (BASDAI), and Bath ankylosing spondylitis metrology index (BASMI) were calculated. A logistic regression model was used to identify the independent risk factors for TOS. Results No differences were observed in terms of demographic characteristics, laboratory findings, or TAS concentrations between the patient and control groups. However, the serum TOS levels were significantly higher in the AS group than in the controls (p=0.003). The comparison of cases of active (BASDAI ≥4) and inactive AS revealed significantly higher TOS levels in the active disease group. The TOS and TAS concentrations did not differ between patients treated with biological agents and those treated with conventional agents. Correlation analysis yielded significant correlations between TOS and TAS, BASMI, BASFI, BASDAI, erythrocyte sedimentation rate (ESR), and high-sensitive C-reactive protein (hs-CRP) (p<0.05; r values ranged from 0.291 to 0.452) and a positive correlation between TAS and BASMI (p<0.05; r=0.344). Based on regression analysis, BASDAI, BASMI, and hs-CRP independently predicted the TOS levels [p<0.05, R2: 0.262, and standard error of the estimate (SEE): 10.96] Conclusion Oxidative stress levels were higher in patients with AS than in healthy

  11. Patient autonomy and relatives' right to know genetic information.

    2007-12-01

    One of the most difficult issues doctors face is a conflict between their professional duties. Such a conflict may arise when doctors know that information has implications not only for patients but also for family members but their duty of confidentiality prevents them from disclosing it. A comparative analysis of English and Israeli medical law reveals that the doctors' duty is based on two principles: a liberal perception of patient autonomy and an overriding utilitarian principle of prevention of harm. However, socio-medical research indicates that these principles do not entirely reflect the views of patients and doctors and are too narrow to deal with the complex situations in practice. Thus, it is argued that the doctor's legal duty of confidentiality should be reconsidered and qualified when it concerns the family. It is suggested that if medical law seeks to recognize the various interests family members have in genetic information then we should consider a different approach, founded on a relational interpretation of autonomy and communitarian notions of solidarity and moral responsibility. This approach perceives confidentiality and privacy as embracing the family unit, based on the view that close relatives are not entirely outside the private sphere of the individual but rather are integral to his or her identity. Thus, to the utilitarian mechanism available in medical law this approach adds a social criterion: The effect any decision (to disclose or not to disclose) will have on the familial relationship and on the dynamics of the particular family. This will provide a more flexible and workable alternative for doctors to resolve familial tensions over access to genetic information.

    Background In patients with type 2 diabetes, the risk for cardiovascular disease is substantial. To achieve a more favourable risk profile, lifestyle changes on diet, physical activity and smoking status are needed. This will involve changes in behaviour, which is difficult to achieve. Cognitive behavioural therapies focussing on self-management have been shown to be effective. We have developed an intervention combining techniques of Motivational Interviewing (MI) and Problem Solving Treatment (PST). The aim of our study is to investigate if adding a combined behavioural intervention to managed care, is effective in achieving changes in lifestyle and cardiovascular risk profile. Methods Patients with type 2 diabetes will be selected from general practices (n = 13), who are participating in a managed diabetes care system. Patients will be randomised into an intervention group receiving cognitive behaviour therapy (CBT) in addition to managed care, and a control group that will receive managed care only. The CBT consists of three to six individual sessions of 30 minutes to increase the patient's motivation, by using principles of MI, and ability to change their lifestyle, by using PST. The first session will start with a risk assessment of diabetes complications that will be used to focus the intervention. The primary outcome measure is the difference between intervention and control group in change in cardiovascular risk score. For this purpose blood pressure, HbA1c, total and HDL-cholesterol and smoking status will be assessed. Secondary outcome measures are quality of life, patient satisfaction, physical activity, eating behaviour, smoking status, depression and determinants of behaviour change. Differences between changes in the two groups will be analysed according to the intention-to-treat principle, with 95% confidence intervals. The power calculation is based on the risk for cardiovascular disease and we calculated that 97 patients should be included in

    Recently a Complexity-Action (CA) duality conjecture has been proposed, which relates the quantum complexity of a holographic boundary state to the action of a Wheeler-DeWitt (WDW) patch in the anti-de Sitter (AdS) bulk. In this paper we further investigate the duality conjecture for stationary AdS black holes and derive some exact results for the growth rate of action within the Wheeler-DeWitt (WDW) patch at late time approximation, which is supposed to be dual to the growth rate of quantum complexity of holographic state. Based on the results from the general D-dimensional Reissner-Nordström (RN)-AdS black hole, rotating/charged Bañados-Teitelboim-Zanelli (BTZ) black hole, Kerr-AdS black hole and charged Gauss-Bonnet-AdS black hole, we present a universal formula for the action growth expressed in terms of some thermodynamical quantities associated with the outer and inner horizons of the AdS black holes. And we leave the conjecture unchanged that the stationary AdS black hole in Einstein gravity is the fastest computer in nature.

    Oncolytic viruses that selectively replicate in tumor cells can be used for treatment of cancer. Accumulating data suggests that virus induced oncolysis can enhance anti-tumor immunity and break immune tolerance. To capitalize on the immunogenic nature of oncolysis, we generated a quadruple modified oncolytic adenovirus expressing granulocyte-macrophage colony-stimulating factor (GMCSF). Ad5/3-E2F-Δ24-GMCSF (CGTG-602) was engineered to contain a tumor specific E2F1 promoter driving an E1 gene deleted at the retinoblastoma protein binding site ("Δ24"). The fiber features a knob from serotype 3 for enhanced gene delivery to tumor cells. The virus was tested preclinically in vitro and in vivo and then 13 patients with solid tumors refractory to standard therapies were treated. Treatments were well tolerated and frequent tumor- and adenovirus-specific T-cell immune responses were seen. Overall, with regard to tumor marker or radiological responses, signs of antitumor efficacy were seen in 9/12 evaluable patients (75%). The radiological disease control rate with positron emission tomography was 83% while the response rate (including minor responses) was 50%. Tumor biopsies indicated accumulation of immunological cells, especially T-cells, to tumors after treatment. RNA expression analyses of tumors indicated immunological activation and metabolic changes secondary to virus replication.

    Background: Confrontation with the consequences of diabetes causes a crisis in physical, mental, and spiritual dimensions. Sometimes the spiritual crisis can be tremendous. Since spiritual health coordinates different aspects of human life, this study aimed to identify the spiritual health of patients with defects caused by diabetes. Materials and Methods: This was a qualitative-phenomenological and descriptive study and the participants were selected from rehabilitation centers in Isfahan and Valiasr Hospital in Zanjan. A purposive sample of 15 participants underwent deep interviews. Colaizzi’s method of analysis was used to analyze the data. Findings: outcome of this phase of the study was 173 codes and 2 groups that included hindering factors in spiritual health and the promotion of the relation with God. The concepts that patients had experienced as hindering factors of the treatment process were disappointment and hopelessness, guilt, feeling distant from God, quitting obligatory acts and knowing God as cruel. The concepts that patients had experienced as contributing factors to the healing process were resorting to Imams, God’s ordering the disease as a reward, fear of God’s punishment, believing in miracles, being closer to God, believing in the mercy of God, returning to religious practice, feeling of enjoying life and knowing that the disease is the atonement of sins. Conclusions: With regard to the importance of spiritual and religious care as one of the tasks of nurses, as the key members of health team, they should respect the patients’ beliefs and values in addition to considering their physical and mental conditions.

    Background An assessment of an individual’s hypertension self-care behavior may provide clinicians and practitioners with important information regarding how to better control hypertension. Objectives The objective of this study was to investigate the self-care behaviors of hypertensive patients. Patients and Methods This cross-sectional study was conducted in 2014 in a sample of 1836 patients of both genders who had been diagnosed with hypertension in urban and rural health centers in the Kohgiluyeh Boyerahmad Province in southern Iran. They were randomly selected and were invited to participate in the study. Self-care activities were measured using the H-hypertension self-care activity level effects. Results The mean age of the respondents was 63 (range: 30 - 92), and 36.1% reported adherence to the recommended levels of medication; 24.5% followed the physical activity level guidelines. Less than half (39.2%) met the criteria for practices related to weight management, and adherence to low-salt diet recommendations was also low (12.3%). Overall, 86.7% were nonsmokers, and 100% abstained from alcohol. The results of a logistic regression indicated that gender was significantly associated with adherence to physical activity (OR = 0.716) and non-smoking (OR = 1.503) recommendations; that is, women were more likely to take part in physical activity than men. There was also a significant association between age and adherence to both a low-salt diet (OR = 1.497) and medication (OR = 1.435). Conclusions Based on our findings, it is crucial to implement well-designed educational programs to improve hypertension self-care behaviors.

    Recurrent focal neuropathy with liability to pressure palsies is a relatively frequent autosomal-dominant demyelinating neuropathy linked to peripheral myelin protein 22 (PMP22) gene deletions. The combination of PMP22 gene mutations with other genetic variants is known to cause a more severe phenotype than expected. We present the case of a patient with severe orthostatic hypotension since 12 years of age, who inherited a PMP22 gene deletion from his father. Genetic double trouble was suspected because of selective sympathetic autonomic disturbances. Through exome-sequencing analysis, we identified two novel mutations in the dopamine beta hydroxylase gene. Moreover, with interactome analysis, we excluded a further influence on the origin of the disease by variants in other genes. This case increases the number of unique patients presenting with dopamine-β-hydroxylase deficiency and of cases with genetically proven double trouble. Finding the right, complete diagnosis is crucial to obtain adequate medical care and appropriate genetic counseling. PMID:26410747

    2016-09-01

    We compute entanglement entropy for free massive scalar fields in anti-de Sitter (AdS) space. The entangling surface is a minimal surface whose boundary is a sphere at the boundary of AdS. The entropy can be evaluated from the thermal free energy of the fields on a topological black hole by using the replica method. In odd-dimensional AdS, exact expressions of the Rényi entropy S n are obtained for arbitrary n. We also evaluate 1-loop corrections coming from the scalar fields to holographic entanglement entropy. Applying the results, we compute the leading difference of entanglement entropy between two holographic CFTs related by a renormalization group flow triggered by a double trace deformation. The difference is proportional to the shift of a central charge under the flow.

    We study segmented strings in flat space and in AdS 3. In flat space, these well known classical motions describe strings which at any instant of time are piecewise linear. In AdS 3, the worldsheet is composed of faces each of which is a region bounded by null geodesics in an AdS 2 subspace of AdS 3. The time evolution can be described by specifying the null geodesic motion of kinks in the string at which two segments are joined. The outcome of collisions of kinks on the worldsheet can be worked out essentially using considerations of causality. We study several examples of closed segmented strings in AdS 3 and find an unexpected quasi-periodic behavior. We also work out a WKB analysis of quantum states of yo-yo strings in AdS 5 and find a logarithmic term reminiscent of the logarithmic twist of string states on the leading Regge trajectory.

    We consider solutions in Einstein-Maxwell theory with a negative cosmological constant that asymptote to global AdS 4 with conformal boundary {S}2× {{{R}}}t. At the sphere at infinity we turn on a space-dependent electrostatic potential, which does not destroy the asymptotic AdS behaviour. For simplicity we focus on the case of a dipolar electrostatic potential. We find two new geometries: (i) an AdS soliton that includes the full backreaction of the electric field on the AdS geometry; (ii) a polarised neutral black hole that is deformed by the electric field, accumulating opposite charges in each hemisphere. For both geometries we study boundary data such as the charge density and the stress tensor. For the black hole we also study the horizon charge density and area, and further verify a Smarr formula. Then we consider this system at finite temperature and compute the Gibbs free energy for both AdS soliton and black hole phases. The corresponding phase diagram generalizes the Hawking-Page phase transition. The AdS soliton dominates the low temperature phase and the black hole the high temperature phase, with a critical temperature that decreases as the external electric field increases. Finally, we consider the simple case of a free charged scalar field on {S}2× {{{R}}}t with conformal coupling. For a field in the SU(N ) adjoint representation we compare the phase diagram with the above gravitational system.

  8. Superstring theory in AdS(3) and plane waves

    NASA Astrophysics Data System (ADS)

    Son, John Sang Won

    This thesis is devoted to the study of string theory in AdS 3 and its applications to recent developments in string theory. The difficulties associated with formulating a consistent string theory in AdS3 and its underlying SL(2, R) WZW model are explained. We describe how these difficulties can be overcome by assuming that the SL(2, R) WZW model contains spectral flow symmetry. The existence of spectral flow symmetry in the fully quantum treatment is proved by a calculation of the one-loop string partition function. We consider Euclidean AdS 3 with the time direction periodically identified, and compute the torus partition function in this background. The string spectrum can be reproduced by viewing the one-loop calculation as the free energy of a gas of strings, thus providing a rigorous proof of the results based on spectral flow arguments. Next, we turn to spacetimes that are quotients of AdS 3, which include the BTZ black hole and conical spaces. Strings propagating in the conical space are described by taking an orbifold of strings in AdS3. We show that the twisted states of these orbifolds can be obtained by fractional spectral flow. We show that the shift in the ground state energy usually associated with orbifold twists is absent in this case, and offer a unified framework in which to view spectral flow. Lastly, we consider the RNS superstrings in AdS 3 x S3 x M , where M may be K3 or T 4, based on supersymmetric extensions of SL(2, R) and SU(2) WZW models. We construct the physical states and calculate the spectrum. A subsector of this theory describes strings propagating in the six dimensional plane wave obtained by the Penrose limit of AdS3 x S3 x M . We reproduce the plane wave spectrum by taking J and the radius to infinity. We show that the plane wave spectrum actually coincides with the large J spectrum at fixed radius, i.e. in AdS3 x S3.

    ADS Labs is a platform that ADS is introducing in order to test and receive feedback from the community on new technologies and prototype services. Currently, ADS Labs features a new interface for abstract searches, faceted filtering of results, visualization of co-authorship networks, article-level recommendations, and a full-text search service. The streamlined abstract search interface provides a simple, one-box search with options for ranking results based on a paper relevancy, freshness, number of citations, and downloads. In addition, it provides advanced rankings based on collaborative filtering techniques. The faceted filtering interface allows users to narrow search results based on a particular property or set of properties ("facets"), allowing users to manage large lists and explore the relationship between them. For any set or sub-set of records, the co-authorship network can be visualized in an interactive way, offering a view of the distribution of contributors and their inter-relationships. This provides an immediate way to detect groups and collaborations involved in a particular research field. For a majority of papers in Astronomy, our new interface will provide a list of related articles of potential interest. The recommendations are based on a number of factors, including text similarity, citations, and co-readership information. The new full-text search interface allows users to find all instances of particular words or phrases in the body of the articles in our full-text archive. This includes all of the scanned literature in ADS as well as a select portion of the current astronomical literature, including ApJ, ApJS, AJ, MNRAS, PASP, A&A, and soon additional content from Springer journals. Fulltext search results include a list of the matching papers as well as a list of "snippets" of text highlighting the context in which the search terms were found.

  10. Catalytic domain of plasmid pAD1 relaxase TraX defines a group of relaxases related to restriction endonucleases

    2013-01-01

    Plasmid pAD1 is a 60-kb conjugative element commonly found in clinical isolates of Enterococcus faecalis. The relaxase TraX and the primary origin of transfer oriT2 are located close to each other and have been shown to be essential for conjugation. The oriT2 site contains a large inverted repeat (where the nic site is located) adjacent to a series of short direct repeats. TraX does not show any of the typical relaxase sequence motifs but is the prototype of a unique family of relaxases (MOBC). The present study focuses on the genetic, biochemical, and structural analysis of TraX, whose 3D structure could be predicted by protein threading. The structure consists of two domains: (i) an N-terminal domain sharing the topology of the DNA binding domain of the MarR family of transcriptional regulators and (ii) a C-terminal catalytic domain related to the PD-(D/E)XK family of restriction endonucleases. Alignment of MOBC relaxase amino acid sequences pointed to several conserved polar amino acid residues (E28, D152, E170, E172, K176, R180, Y181, and Y203) that were mutated to alanine. Functional analysis of these mutants (in vivo DNA transfer and cleavage assays) revealed the importance of these residues for relaxase activity and suggests Y181 as a potential catalytic residue similarly to His-hydrophobe-His relaxases. We also show that TraX binds specifically to dsDNA containing the oriT2 direct repeat sequences, confirming their role in transfer specificity. The results provide insights into the catalytic mechanism of MOBC relaxases, which differs radically from that of His-hydrophobe-His relaxases. PMID:23904483

  11. Does adding noradrenaline reuptake inhibition to selective serotonin reuptake inhibition improve efficacy in patients with depression? A systematic review of meta-analyses and large randomised pragmatic trials.

    Selective serotonin reuptake inhibitors (SSRIs) are recommended as first-line pharmacological treatment for depression and are the most commonly prescribed class of antidepressants. However, there is substantial evidence that noradrenaline has a role in the pathogenesis and treatment of depression. This review aims to examine the evidence of including noradrenaline reuptake inhibition with serotonin reuptake inhibition with respect to increasing efficacy in the treatment of depression. Evidence from meta-analysis of randomised controlled trials (RCTs) and randomised pragmatic trials was found in support of greater efficacy of the serotonin noradrenaline reuptake inhibitors (SNRIs), venlafaxine and duloxetine, in moderate to severe depression compared to SSRIs but no evidence was found for superiority of milnacipran. There is sufficient current evidence that demonstrates an increase in efficacy, when noradrenaline reuptake is added to serotonin (5-HT) reuptake, to suggest that patients with severe depression or those who have failed to reach remission with a SSRI may benefit from treatment with a SNRI. However, as these conclusions are drawn from the evidence derived from meta-analyses and pragmatic trials, large adequately powered RCTs using optimal dosing regimens and clinically relevant outcome measures in severe depression and SSRI treatment failures are still required to confirm these findings.

    This cross-sectional international survey assessed patients' perceptions of their wound pain. A total of 2018 patients (57% female) from 15 different countries with a mean age of 68.6 years (SD = 15.4) participated. The wounds were categorised into ten different types with a mean wound duration of 19.6 months (SD = 51.8). For 2018 patients, 3361 dressings/compression systems were being used, with antimicrobials being reported most frequently (n= 605). Frequency of wound-related pain was reported as 32.2%, 'never' or 'rarely', 31.1%, 'quite often' and 36.6%, 'most' or 'all of the time', with venous and arterial ulcers associated with more frequent pain (P= 0.002). All patients reported that 'the wound itself' was the most painful location (n= 1840). When asked if they experienced dressing-related pain, 286 (14.7%) replied 'most of the time' and 334 (17.2%) reported pain 'all of the time'; venous, mixed and arterial ulcers were associated with more frequent pain at dressing change (P < 0.001). Eight hundred and twelve (40.2%) patients reported that it took <1 hour for the pain to subside after a dressing change, for 449 (22.2%) it took 1-2 hours, for 192 (9.5%) it took 3-5 hours and for 154 (7.6%) patients it took more than 5 hours. Pain intensity was measured using a visual analogue scale (VAS) (0-100) giving a mean score of 44.5 (SD = 30.5, n= 1981). Of the 1141 who reported that they generally took pain relief, 21% indicated that they did not feel it was effective. Patients were asked to rate six symptoms associated with living with a chronic wound; 'pain' was given the highest mean score of 3.1 (n= 1898). In terms of different types of daily activities, 'overdoing things' was associated with the highest mean score (mean = 2.6, n= 1916). During the stages of the dressing change procedure; 'touching/handling the wound' was given the highest mean score of 2.9, followed by cleansing and dressing removal (n= 1944).

    Background: Occurrence of hypotension during hemodialysis in nearly 20-30% of patients, shows is the necessity of continuous monitoring the patients' blood pressure during hemodialysis. Since directly and non-invasively continuous blood pressure monitoring, is not easy, finding a parameter related to blood pressure, for indirect monitoring is of great value. Related blood volume (RBV) is one of the parameters, related to blood pressure and have a good potential to reflect the patient’s hemodynamic condition. Objectives: The main objective of this study was to design and construct an optical device to determine the RBV in patients undergoing hemodialysis, during the process. Materials and Methods: After initial studies in order to select a proper sensor, using the ORCAD software, an analog circuit was designed. The implementation and modification of the circuit was done by the clinical tests, using expired blood. Afterwards, for calculation the RBV, controlling the display, data storage and sending it to the computer, an ATmega16 microcontroller was used. For programing the microcontroller, CodeVision software and then Altium Designer software were used for the circuit compression, in order to design the printed circuit board. Finally, all parts of the analog and digital circuit, AC to DC converter and the LCD were embedded in a box. Results: After finalization of the device and before testing it in a real situation, expired blood was used for final evaluation. The evaluation was done by changing the blood concentration, at the start point by adding water to it. In fact, the device can track the changes in blood concentration and display the RBV. After this evaluation, the device was tested in a clinical situation. The results showed there are no interactions between this device and the other devices used in the dialysis section and it can work properly in order to measure the RBV. Conclusions: Considering the hypotension and its consequences in a patient on

    It is shown how the static-gauge world-volume superfield actions of diverse superbranes on the AdS{sub d+1} superbackgrounds can be systematically derived from nonlinear realizations of the appropriate AdS supersymmetries. The latter are treated as superconformal symmetries of flat Minkowski superspaces of the bosonic dimension d. Examples include the N = 1 AdS{sub 4} supermembrane, which is associated with the 1/2 partial breaking of the OSp(1|4) supersymmetry down to the N = 1, d = 3 Poincare supersymmetry, and the T-duality related L3-brane on AdS{sub 5} and scalar 3-brane on AdS{sub 5} x S{sup 1}, which are associated with two different patterns of 1/2 breaking of the SU(2, 2|1) supersymmetry. Another (closely related) topic is the AdS/CFT equivalence transformation. It maps the world-volume actions of the codimension-one AdS{sub d+1} (super)branes onto the actions of the appropriate Minkowski (super)conformal field theories in the dimension d.

    The National Association of Medical Examiners Ad Hoc Committee on the Definition of Heat-Related Fatalities recommends the following definition of "heat-related death": a death in which exposure to high ambient temperature either caused the death or significantly contributed to it. The committee also recommends that the diagnosis of heat-related death be based on a history of exposure to high ambient temperature and the reasonable exclusion of other causes of hyperthermia. The diagnosis may be established from the circumstances surrounding the death, investigative reports concerning environmental temperature, and/or measured antemortem body temperature at the time of collapse. In cases where the measured antemortem body temperature at the time of collapse was > or = 105 degrees F (> or = 40.6 degrees C), the cause of death should be certified as heat stroke or hyperthermia. Deaths may also be certified as heat stroke or hyperthermia with lower body temperatures when cooling has been attempted prior to arrival at the hospital and/or when there is a clinical history of mental status changes and elevated liver and muscle enzymes. In cases where the antemortem body temperature cannot be established but the environmental temperature at the time of collapse was high, an appropriate heat-related diagnosis should be listed as the cause of death or as a significant contributing condition.

    Introduction When first line therapy with metformin is insufficient for patients with type 2 diabetes (T2D), the optimal adjunctive therapy is unclear. We assessed the efficacy and safety of adjunctive antidiabetic agents in patients with inadequately controlled T2D on metformin alone. Materials and Methods A search of MEDLINE and CENTRAL, clinicaltrials.gov, regulatory websites was performed. We included randomized controlled trials of 3–12 months duration, evaluating Food and Drug Administration or European Union approved agents (noninsulin and long acting, once daily basal insulins) in patients experiencing inadequate glycemic control with metformin monotherapy (≥1500 mg daily or maximally tolerated dose for ≥4 weeks). Random-effects network meta-analyses were used to compare the weighted mean difference for changes from baseline in HbA1c, body weight (BW) and systolic blood pressure (SBP), and the risk of developing hypoglycemia, urinary (UTI) and genital tract infection (GTI). Results Sixty-two trials evaluating 25 agents were included. All agents significantly reduced HbA1c vs. placebo; albeit not to the same extent (range, 0.43% for miglitol to 1.29% for glibenclamide). Glargine, sulfonylureas (SUs) and nateglinide were associated with increased hypoglycemia risk vs. placebo (range, 4.00–11.67). Sodium glucose cotransporter-2 (SGLT2) inhibitors, glucagon-like peptide-1 analogs, miglitol and empagliflozin/linagliptin significantly reduced BW (range, 1.15–2.26kg) whereas SUs, thiazolindinediones, glargine and alogliptin/pioglitazone caused weight gain (range, 1.19–2.44kg). SGLT2 inhibitors, empagliflozin/linagliptin, liraglutide and sitagliptin decreased SBP (range, 1.88–5.43mmHg). No therapy increased UTI risk vs. placebo; however, SGLT2 inhibitors were associated with an increased risk of GTI (range, 2.16–8.03). Conclusions Adding different AHAs to metformin was associated with varying effects on HbA1c, BW, SBP, hypoglycemia, UTI and GTI

    The article describes the problem of corruption occurring in the relationship between doctor and patient. The doctor-patient relationship, including the provision of health services, is one of several potential areas of corruption in the health care system. Among the reasons for the existence of corruption in these relationships are the need to obtain better healthcare for the patient, and higher earnings in the case of a doctor. Indications of corruption are utilitarian (action for personal advantage without ethical aspects), but may also be (actually or in the patient's opinion) the only way to obtain services and save health and even life. Corruption between the doctor and the patient can be limited by better organization of the health care system, including the financing of benefits and education of medical personnel and patients, as well as traditional legal measures, such as prevention or the application of criminal sanctions.

    Our aim was to study the impact of information on the behaviour of patients who were to have an oral biopsy specimen taken. Patients were randomly assigned either to be given the basic information about oral biopsy or a more extensive amount of information. The Krantz Health Opinion Survey was used as a measure of preferences in decisions made about oral biopsy, and we used a questionnaire to assess anxiety. A total of 260 patients were studied. The participants were satisfied with the information provided (both form and content), but significantly more of those given basic information would have liked to know more (p=0.02). We conclude that information exerts a clear effect on patients' attitude to oral biopsy. Provision of preoperative information leads to significantly less anxiety in all patients having a procedure under local anaesthesia. The results emphasise that patients need to be adequately informed about oral biopsy.

    An elderly female patient with an uncomplicated urinary tract infection from Salmonella newport is presented. Radiological and laboratory studies were performed because of her systemic and exposure risk factors as well as prior urinary tract abnormalities. While this patient was successfully treated as an outpatient with oral antibiotics, complications and recurrence are common and deserve close follow-up with repeat urine cultures at a minimum. Further laboratory and radiological testing should be guided by patient gender, risk factors and recurrence. PMID:25193813

    Generalizing the first law of thermodynamics, the increase in entropy density δ S (x ) of a conformal field theory (CFT) is proportional to the increase in energy density, δ E (x ) , of a subsystem divided by a spatially dependent entanglement temperature, TE(x ) , a fixed parameter determined by the geometry of the subsystem, crossing over to thermodynamic temperature at high temperatures. In this paper we derive a generalization of the thermodynamic Clausius relation, showing that deformations of the CFT by marginal operators are associated with spatial temperature variations, δ TE(x ) , and spatial energy correlations play the role of specific heat. Using AdS/CFT duality we develop a relationship between a perturbation in the local entanglement temperature of the CFT and the perturbation of the bulk AdS metric. In two dimensions, we demonstrate a method through which direct diagonalizations of the boundary quantum theory may be used to construct geometric perturbations of AdS3 .

    GluA1, GluA2, GluA3, and GluA4 are the constitutive subunits of amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs), the major mediators of fast excitatory transmission in the mammalian central nervous system. Most AMPARs are Ca(2+)-impermeable because of the presence of the GluA2 subunit. GluA2 mRNA undergoes an editing process that results in a Q-R substitution, a key factor in the regulation of AMPAR Ca(2+)-permeability. AMPARs lacking GluA2 or containing the unedited subunit are permeable to Ca(2+) and Zn(2+). The phenomenon physiologically modulates synaptic plasticity while, in pathologic conditions, leads to increased vulnerability to excitotoxic neuronal death. Given the importance of these subunits, we have therefore evaluated possible associations between changes in expression levels of AMPAR subunits and development of cognitive deficits in 3xTg-AD mice, a widely investigated transgenic mouse model of Alzheimer's disease (AD). With quantitative real-time PCR analysis, we assayed hippocampal mRNA expression levels of GluA1-4 subunits occurring in young [3 months of age (m.o.a.)] and old (12 m.o.a) Tg-AD mice and made comparisons with levels found in age-matched wild type (WT) mice. Efficiency of GluA2 RNA editing was also analyzed. All animals were cognitively tested for learning short- and long-term spatial memory with the Morris Water Maze (MWM) navigation task. 3xTg-AD mice showed age-dependent decreases of mRNA levels for all the AMPAR subunits, with the exception of GluA2. Editing remained fully efficient with aging in 3xTg-AD and WT mice. A one-to-one correlation analysis between MWM performances and GluA1-4 mRNA expression profiles showed negative correlations between GluA2 levels and MWM performances in young 3xTg-AD mice. On the contrary, positive correlations between GluA2 mRNA and MWM performances were found in young WT mice. Our data suggest that increases of AMPARs that contain GluA1, GluA3, and GluA4 subunits may help in

    The recurrence rate of neuropathic foot ulcers is reported in 51 diabetic patients regularly attending a diabetic foot clinic. All of the patients were provided with protective footwear reducing peak plantar pressure at the forefoot area by 50% (versus normal shoes), and were followed up for up to 4 years. Compliance with this footwear was recorded by assessing the daily time of wearing protective or normal shoes, and compliance with foot care was recorded from the entries in the patients charts. The results of this observational study demonstrate that wearing protective shoes for > 60% of the daytime significantly (p = 0.0002) reduced the ulcer relapse rate by > 50% in comparison with shorter wearing times for these shoes. In addition, patients without ulcer relapses had foot care significantly more frequently than patients with relapse (p < 0.05). It is concluded that cushioned protective footwear in association with frequent foot care is essential in the prevention of neuropathic diabetic foot ulcer recurrence.

    We review recent work on the holographic duals of type II and heterotic matrix string theories described by warped AdS3 supergravities. In particular, we compute the spectra of Kaluza-Klein primaries for type I, II supergravities on warped AdS3 × S7 and match them with the primary operators in the dual two-dimensional gauge theories. The presence of non-trivial warp factors and dilaton profiles requires a modification of the familiar dictionary between masses and 'scaling' dimensions of fields and operators. We present these modifications for the general case of domain wall/QFT correspondences between supergravities on warped AdSd+1 × Sq geometries and super Yang-Mills theories with 16 supercharges.

    Poor survival of older cervical cancer patients has been reported; however, related factors, such as the extent of disease and the competitive risk by aging have not been well evaluated. We applied the relative survival model developed by Dickman et al to resolve this issue. Study subjects were cervical cancer patients retrieved from the Osaka Cancer Registry. They were limited to the 10,048 reported cases diagnosed from 1975 to 1999, based on the quality of data collection on vital status. Age at diagnosis was categorized into <30, 30-54, 55-64, and > or = 65 years. The impact of prognostic factors on 5-year survival was evaluated with the relative survival model, incorporating patients' expected survival in multivariate analysis. The age-specific relative excess risk (RER) of death was significantly higher for older groups as compared with women aged 30-54 years (RER, 1.58 at 55-64 and 2.51 at > or = 65 years). The RER was decreased by 64.8% among the 55-64 year olds as an effect of cancer stage at diagnosis, and by 43.4% among those 65 years old and over. After adding adjustment for treatment modalities, the RER was no longer significantly higher among 55-64 year olds; however, it was still higher among 65 year olds and over. Advanced stage at diagnosis was the main determinant of poor survival among the aged cervical cancer patients, although other factors such as limitations on the combination of treatment were also suggested to have an influence in those aged 65 years and over.

    Quaking (QKI) is a gene exclusively expressed within glial cells. QKI has previously been implicated in various neurological disorders and diseases, including Alzheimer’s disease (AD), a condition for which increasing evidence suggests a central role of glia cells. The objective of the present study was to investigate the expression levels of QKI and three QKI isoforms (QKI5, QKI6, and QKI7) in AD. Genes that have previously been related to the ontogeny and progression of AD, specifically APP, PSEN1, PSEN2, and MAPT, were also investigated. A real-time PCR assay of 123 samples from human postmortem sporadic AD patients and control brains was performed. The expression values were analyzed with an analysis of covariance model and subsequent multiple regressions to explore the possibility of related expression values between QKI, QKI isoforms, and AD-related genes. Further, the sequences of AD-related genes were analyzed for the presence of QKI binding domains. QKI and all measured QKI isoforms were found to be significantly upregulated in AD samples, relative to control samples. However, APP, PSEN1, PSEN2, and MAPT were not found to be significantly different. QKI and QKI isoforms were found to be predictive for the variance of APP, PSEN1, PSEN2, and MAPT, and putative QKI binding sites suggests an interaction with QKI. Overall, these results implicate a possible role of QKI in AD, although the exact mechanism by which this occurs remains to be uncovered. PMID:27163826

    Background The combined therapy of bevacizumab (BEV) with taxane (paclitaxel or docetaxel) has shown an improvement on progression-free survival (PFS) and objective remission in Her2-negative patients with locally recurrent or metastatic breast cancer (LR/MBC). However, there was no benefit in overall survival (OS). The aim of this study was to evaluate the efficacy and safety of adding an agent to the BEV/taxane regimens for the treatment of Her2-negative patients with LR/MBC in a first-line setting. Materials and methods We searched PubMed, Web of Science, EMBASE, EBSCO, and the Cochrane Library databases for eligible trials. A meta-analysis was performed using Review Manager 5.0 freeware package. We calculated the hazard ratio (HR) for PFS and OS. The odds ratio (OR) was used to calculate objective response rate (ORR) and grade 3/4 drug-related adverse events. The heterogeneity of study outcomes was calculated by the χ2 test or I2 statistics. Results A total of 1,124 patients from seven randomized controlled trials were analyzed. Our meta-analysis showed that the ORR was significantly improved in the BEV/taxane-based triplet group when compared with the BEV/taxane-based doublet group (OR =1.31, 95% confidence interval [CI]: 1.03–1.67, P=0.03). A subset analysis showed that a similar result was achieved in the triplet group in which a cytotoxic agent was added (OR =1.46, 95% CI: 1.09–1.95, P=0.01). However, the PFS and OS had no statistically significant differences between the two groups (HR =0.87, 95% CI: 0.68–1.13, P=0.31; HR =0.98, 95% CI: 0.82–1.16, P=0.78, respectively). Regarding safety, thromboembolic events, fatigue, and diarrhea (all $grade 3) were more frequently observed in the BEV/taxane-based triplet group (OR =3.8, 95% CI: 1.86–7.79, P=0.0003; OR =1.55, 95% CI: 1.05–2.27, P=0.03; OR =2.1, 95% CI: 1.29–3.41, P=0.003, respectively). Other toxic effects had no statistically significant differences between the two groups. Conclusion Our

    Cancer-related direct-to-consumer advertising (DTCA) is controversial because cancer treatment is complex and entails more risks and costs than typical treatments that are advertised for other conditions. Drawing from the Structural Influence Model of Communication, this study explores communication inequalities in DTCA exposure across social determinants among a population-based sample of 2013 patients diagnosed with breast, prostate, or colorectal cancers. Three survey items assessed patients' frequency of encountering ads concerning treatment alternatives for cancer, dealing with side effects of treatment, and doctors or hospitals offering services for cancer following their diagnosis. The analysis showed that overall exposure to DTCA in this study population was modest (median was once per week). Breast cancer patients reported significantly higher exposure to all three ad categories and overall DTCA exposure than prostate and colorectal cancer patients. Older patients consistently reported lower overall exposure to DTCA across the three cancer types. Other significant correlates included ethnicity (higher exposures among African American prostate cancer patients vs. White; lower exposures in Hispanic colorectal cancer patients vs. White) and cancer stage (higher exposures in Stage IV prostate cancer patients vs. Stages 0-II). Education level did not predict patients' DTCA exposure. The implications of these observed inequalities in DTCA exposure on cancer outcomes are discussed. PMID:25357119

    Pain may be the earliest symptom in Fabry disease and presents with a distinct phenotype including triggerable pain attacks, evoked pain, pain crises, and chronic pain. Current pain questionnaires do not reflect the special phenotype of Fabry disease-associated pain, which hampers its systematic evaluation as the basis of correct diagnosis and effective treatment. A questionnaire specifically designed to assess Fabry disease-associated pain is thus urgently needed. At the Würzburg Fabry Center for Interdisciplinary Therapy (FAZIT), Germany, we developed and validated the first face-to-face Fabry Pain Questionnaire (FPQ) for adult patients. The initial version of the FPQ was tested in a pilot study with 20 consecutive Fabry disease patients. The performance of the revised FPQ was assessed in a first (n=56) and second (n=20) validation phase in consecutive Fabry disease patients. For this, patients were interviewed at baseline and 2 weeks later. We determined the test-retest reliability and validity of the FPQ in comparison to data obtained with the Neuropathic Pain Symptom Inventory. The FPQ contains 15 questions on the 4 pain phenotypes of Fabry disease (pain attacks, pain crises, evoked pain, chronic pain) in childhood and adulthood, on pain development during life with and without enzyme replacement therapy, and on everyday life impairment due to pain. This first disease-specific questionnaire is a valuable tool for baseline and follow-up assessment of pain in Fabry disease patients and may guide treatment in this distinct pain phenotype.

    Nurse educators are responsible for accompanying students towards becoming capable, competent professional nurses who are a credit to themselves, their patients, colleagues and profession. Student nurses need, therefore, to be taught to render comprehensive nursing care to patients in all stages of their lives, including when they are dying. Being confronted with human suffering and death is challenging and traumatic. Those exposed to such events on a daily basis need to have a solid foundation of self preservation to see past the pain of suffering and to bring light and hope to those in need. A young student nurse will only experience positive growth and development in these circumstances if she is also cared for and guided with understanding. The researcher utilized a qualitative, explorative, descriptive and contextual design based on the phenomenological approach to enquiry. The following question was asked at the beginning of each unstructured phenomenological interview: "How was if for you to care for a dying or deceased patient?" The central theme identified that student nurses experience turmoil in their different relationships in their accompaniment of the dying patient. Guidelines based on the central theme and sub-themes that emerged from raw data, as well as literature, are offered as strategies to promote/enhance optimal accompaniment of student nurses caring for the dying patient.

    Abnormal accumulation of the microtubule-interacting protein tau is associated with neurodegenerative diseases including Alzheimer’s disease (AD). β-amyloid (Aβ) lies upstream of abnormal tau behavior, including detachment from microtubules, phosphorylation at several disease-specific sites, and self-aggregation into toxic tau species in AD brains. To prevent the cascade of events leading to neurodegeneration in AD, it is essential to elucidate the mechanisms underlying the initial events of tau mismetabolism. Currently, however, these mechanisms remain unclear. In this study, using transgenic Drosophila co-expressing human tau and Aβ, we found that tau phosphorylation at AD-related Ser262/356 stabilized microtubule-unbound tau in the early phase of tau mismetabolism, leading to neurodegeneration. Aβ increased the level of tau detached from microtubules, independent of the phosphorylation status at GSK3-targeted SP/TP sites. Such mislocalized tau proteins, especially the less phosphorylated species, were stabilized by phosphorylation at Ser262/356 via PAR-1/MARK. Levels of Ser262 phosphorylation were increased by Aβ42, and blocking this stabilization of tau suppressed Aβ42-mediated augmentation of tau toxicity and an increase in the levels of tau phosphorylation at the SP/TP site Thr231, suggesting that this process may be involved in AD pathogenesis. In contrast to PAR-1/MARK, blocking tau phosphorylation at SP/TP sites by knockdown of Sgg/GSK3 did not reduce tau levels, suppress tau mislocalization to the cytosol, or diminish Aβ-mediated augmentation of tau toxicity. These results suggest that stabilization of microtubule-unbound tau by phosphorylation at Ser262/356 via the PAR-1/MARK may act in the initial steps of tau mismetabolism in AD pathogenesis, and that such tau species may represent a potential therapeutic target for AD.

    We investigate the structure of two-point functions for the quantum field theory dual to an asymptotically Lorentzian Anti de Sitter (AdS) wormhole. The bulk geometry is a solution of five-dimensional second-order Einstein-Gauss-Bonnet gravity and causally connects two asymptotically AdS spacetimes. We revisit the Gubser-Klebanov-Polyakov-Witten prescription for computing two-point correlation functions for dual quantum field theories operators O in Lorentzian signature and we propose to express the bulk fields in terms of the independent boundary values {phi}{sub 0}{sup {+-}} at each of the two asymptotic AdS regions; along the way we exhibit how the ambiguity of normalizable modes in the bulk, related to initial and final states, show up in the computations. The independent boundary values are interpreted as sources for dual operators O{sup {+-}} and we argue that, apart from the possibility of entanglement, there exists a coupling between the degrees of freedom living at each boundary. The AdS{sub 1+1} geometry is also discussed in view of its similar boundary structure. Based on the analysis, we propose a very simple geometric criterion to distinguish coupling from entanglement effects among two sets of degrees of freedom associated with each of the disconnected parts of the boundary.

    We study the complex scalar loop corrections to the boundary-boundary gauge two-point function in pure AdS space in Poincare coordinates, in the presence of boundary quadratic perturbations to the scalar. These perturbations correspond to double-trace perturbations in the dual CFT and modify the boundary conditions of the bulk scalars in AdS. We find that, in addition to the usual UV divergences, the one-loop calculation suffers from a divergence originating in the limit as the loop vertices approach the AdS horizon. We show that this type of divergence is independent of the boundary coupling; making use of this we extract the finite relative variation of the imaginary part of the loop via Cutkosky rules as the boundary perturbation varies. Applying our methods to compute the effects of a time-dependent impurity to the conductivities using the replica trick in AdS/CFT, we find that generally an IR-relevant disorder reduces the conductivity and that in the extreme low frequency limit the correction due to the impurities overwhelms the planar CFT result even though it is supposedly 1/N{sup 2} suppressed. We also comment on the more physical scenario of a time-independent impurity.

    There is a "confusion of tongues" in the communication between patient and physician that hinders mutual understanding. Cancer - because of its malignant and often chronic nature - accentuates the communication problems and emphasizes the importance of human relationship. The confusion of tongues can only be resolved through understanding of the situation and motivations of the other person. Thus our aim is to help medical doctors to recognize and understand the most important communication characteristics of the doctor-patient interactions that are strained by the burden of cancer. Interviews with directly concerned professionals and non-professionals were recorded in order to reveal the most common communication disturbances. The majority of the "communication vacuum" arose when bad news should be disclosed for the patient, as bad news is bad for the physician as well. It is emotionally burdening to perceive bad news, and a big challenge for the physician to break it gently, to be tactful, while he/she has no possibility to pay attention with regard to his/her own emotional stability. Medical doctors can cope with this challenge if they are acquainted with the psychological difficulties of the patients that block the effective medical communication.

    Abstract Although trauma-associated mortality has fallen in recent decades, and medical care has continued to improve in many fields, the quality of life after experiencing polytrauma has attracted little attention in the literature. This group of patients suffer from persisting physical disabilities. Moreover, they experience long-term social, emotional, and psychological effects that limit/lower considerably their quality of life. We analyzed retrospective data on 147 polytraumatized patients by administering written questionnaires and conducting face-to-face interviews 6 ± 0.8 years after the trauma in consideration of the following validated scores: Glasgow Outcome Scale, European Quality of Life Score, Short Form-36, Trauma Outcome Profile, and Beck Depressions Inventory II. Our analysis of these results reveals that polytraumatized patients suffer from persistent pain and functional disabilities after >5 years. We also observed changes in their socioeconomic situation, as well as psychological after-effects. The rehabilitation of this particular group of patients should not only address their physical disabilities. The psychological after-effects of trauma must be acknowledged and addressed for an even longer period of time. PMID:27175646

    Background Hyponatremia has been known as an important predictor of clinical outcomes in patients with heart failure (HF). While information on hyponatremia in patients with HF has been available abundantly, information on factors associated with increased risk of developing hospital-acquired hyponatremia (HAH) is still limited. Objective To identify patients and medication-related factors associated with HAH in patients hospitalized from HF. Setting Fatmawati Hospital in Jakarta, Indonesia. Methods This is a nested case-control study with patients developing HAH served as case group and each patient in case group was matched by age and gender to three patients in control group. Patients included in this study are patients hospitalized from HF, and coded with I.50 according to ICD-10, during 2011-2013 at Fatmawati Hospital in Jakarta, Indonesia. Information retrieved from patients' medical records included demographic profiles, vital signs and symptoms at admission, past medical history, medication during hospitalization and clinical chemistry laboratory records. Multivariable logistic regression analysis was performed to find out patient and treatment-related factors associated with the development of HAH. Main outcome measures Patients and medication related factors having significant association with HAH. Results Four hundreds sixty-four patients were included in this study and 45 of them (9.7 %) met criteria of developing HAH so then, accordingly, 135 patients were selected as controls. 36 patient- and 22 treatment-related factors were analyzed in univariate logistic regression resulted in 20 factors having p value <0.2 and were included in multivariable logistic regression analysis. Final factors showing significant association with HAH are presence of ascites at admission (odds ratio = 4.7; 95 % confidence interval 1.9-11.5) and administration of amiodarone (3.2; 1.3-7.4) and heparin (3.1; 1.2-7.3) during hospital stay.

    BMI is widely used as a measure of weight status and disease risks; it defines overweight and obesity based on statistical criteria. BMI is a score; neither is it biologically sound nor does it reflect a suitable phenotype worthwhile to study. Because of its limited value, BMI cannot provide profound insight into obesity biology and its co-morbidity. Alternative assessments of weight status include detailed phenotyping by body composition analysis (BCA). However, predicting disease risks, fat mass, and fat-free mass as assessed by validated techniques (i.e., densitometry, dual energy X ray absorptiometry, and bioelectrical impedance analysis) does not exceed the value of BMI. Going beyond BMI and descriptive BCA, the concept of functional body composition (FBC) integrates body components into regulatory systems. FBC refers to the masses of body components, organs, and tissues as well as to their inter-relationships within the context of endocrine, metabolic and immune functions. FBC can be used to define specific phenotypes of obesity, e.g. the sarcopenic-obese patient. Well-characterized obesity phenotypes are a precondition for targeted research (e.g., on the genomics of obesity) and patient-centered care (e.g., adequate treatment of individual obese phenotypes such as the sarcopenic-obese patient). FBC contributes to a future definition of overweight and obesity based on physiological criteria rather than on body weight alone. PMID:27286962

    Making sense of psychoses supports insight and personal recovery. Relatives' and clinicians' different perspectives on psychoses might impede such processes e.g., in family interventions. This study compares the meaning of psychosis as perceived by patients, their relatives and clinicians and investigates factors associated with discrepancies between them. Meaning of psychosis was assessed in 70 interrelated patients, relatives and clinicians with the SUSE-questionnaire. Severity of disorder, therapeutic relationship and other clinical variables were analysed in patient groups with deviant SUSE-ratings compared to their relative or clinician respectively. The majority of patient-relative- and patient-clinician-dyads made equal ratings of meaning of psychosis. Relatives and clinicians tended to have a less optimistic view on long-term-effects than patients. Discrepancy in ratings between patients and relatives was best explained by the family relationship (i.e. not being a parent) and between patients and clinicians by the severity of positive symptoms. Strong consensus was found among patients, relatives and clinicians about a relatively positive, meaningful picture of psychosis. Sufficient opportunities to discuss experiences and understanding of psychosis help to make sense of it consensually. If clinicians' attitudes towards psychosis are negatively biased by symptomatology, they will struggle to see and support personal recovery.

    Most people who die in the Netherlands receive medical care during the final stage of their life. Since the 19th century, when a sombre prognosis was often the only medical intervention available, sophisticated diagnostic procedures and curative victories have forced elementary bedside manners into retreat. However, modern medicine is rediscovering its boundaries; the inevitability of death and the human tragedy of dying. The renewed interest in letters of condolence from doctors to the family of their deceased patients is an example of this. These letters provide the physician with an opportunity for worthy and effective behaviour under trying circumstances.

    Reproducibility and validity testing of appetite ratings and energy intakes are needed in experimental and natural settings. Eighteen healthy young women ate a standardized breakfast for 8 days. Days 1 and 8, they rated their appetite (Hunger, Fullness, Desire to Eat, Prospective Food Consumption (PFC)) over a 3.5 h period using visual analogue scales, consumed an ad libitum lunch, left the research center and recorded food intake for the remainder of the day. Days 2-7, participants rated their at-home Hunger at 0 and 30 min post-breakfast and recorded food intake for the day. Total area under the curve (AUC) over the 180 min period before lunch, and energy intakes were calculated. Reproducibility of satiety measures between days was evaluated using coefficients of repeatability (CR), coefficients of variation (CV) and intra-class coefficients (ri). Correlation analysis was used to examine validity between satiety measures. AUCs for Hunger, Desire to Eat and PFC (ri = 0.73-0.78), ad libitum energy intakes (ri = 0.81) and total day energy intakes (ri​ = 0.48) were reproducible; fasted ratings were not. Average AUCs for Hunger, Desire to Eat and PFC, Desire to Eat at nadir and PFC at fasting, nadir and 180 min were correlated to total day energy intakes (r = 0.50-0.77, P < 0.05), but no ratings were correlated to lunch consumption. At-home Hunger ratings were weakly reproducible but not correlated to reported total energy intakes. Satiety ratings did not concur with next meal intake but PFC ratings may be useful predictors of intake. Overall, this study adds to the limited satiety research on women and challenges the accepted measures of satiety in an experimental setting. PMID:26763471

    Background Patients with mixed hyperlipidemia usually are in need of combination therapy to achieve low-density lipoprotein cholesterol (LDL-C) and triglyceride (TG) target values for reduction of cardiovascular risk. This study investigated the efficacy and safety of adding a new hypolipidemic agent, coenzyme A (CoA) to stable statin therapy in patients with mixed hyperlipidemia. Methods In this multi-center, 8-week, double-blind study, adults who had received ≥8 weeks of stable statin therapy and had hypertriglyceridemia (TG level at 2.3-6.5 mmol/L) were randomized to receive CoA 400 U/d or placebo plus stable dosage of statin. Efficacy was assessed by the changes in the levels and patterns of lipoproteins. Tolerability was assessed by the incidence and severity of adverse events (AEs). Results A total of 304 patients with mixed hyperlipidemia were randomized to receive CoA 400 U/d plus statin or placebo plus statin (n = 152, each group). After treatment for 8 weeks, the mean percent change in TG was significantly greater with CoA plus statin compared with placebo plus statin (-25.9% vs -4.9%, respectively; p = 0.0003). CoA plus statin was associated with significant reductions in TC (-9.1% vs -3.1%; p = 0.0033), LDL-C (-9.9% vs 0.1%; p = 0.003), and non- high-density lipoprotein cholesterol (-13.5% vs -5.7%; p = 0.0039). There was no significant difference in the frequency of AEs between groups. No serious AEs were considered treatment related. Conclusions In these adult patients with persistent hypertriglyceridemia, CoA plus statin therapy improved TG and other lipoprotein parameters to a greater extent than statin alone and has no obviously adverse effect.

    Radiation dosages to sensitive organs in full spine radiography have in recent years been a concern of physicians as well as the general public. The spine is the prime target for exposure in scoliosis radiography, though the exposure usually necessitates irradiation of several radio-sensitive organs. In recent studies, various protection techniques have been used including various lead and aluminum filtration systems, altered patient positioning and varied tube-film distances. The purpose of this study was to evaluate the efficiency for radiation dosage reduction of three filtration systems used frequently in the chiropractic profession. The systems tested were the Nolan Multiple X-ray Filters, the Clear-Pb system and the Sportelli Wedge system. These systems were tested in seven configurations varying breast shielding, distance and patient positioning. All systems tested demonstrated significant radiation reductions to organs, especially breast tissue. The Clear-Pb system appeared to be the most effective for all organs except the breast, and the Sportelli Wedge system demonstrated the greatest reduction to breast tissue.

    The aim of this study was to identify disease-related knowledge and information needs of patients with inflammatory bowel disease. The 313 patients (Crohn disease: n = 169, colitis: n = 144) presenting to an outpatient gastroenterology clinic of a tertiary care hospital in Seoul, Republic of Korea, were scored on their knowledge of Crohn disease and colitis and their information needs were assessed in the questionnaire. Patients with Crohn disease obtained a higher mean knowledge score than patients with colitis. The patients with Crohn disease had significantly higher scores about complications than patients with colitis. The patients with Crohn disease showed significantly higher mean scores relating to the patients' information needs than patients with colitis. The favorite topics of information needed were disease, medication, and diagnosis/operations. The patients with Crohn disease wanted more information than patients with colitis about medications used for treatment, daily life, and pregnancy. The effectiveness of the training and education given to patients can be maximized in this education system when the information about disease and medications for Crohn disease patients or information about disease and diet for colitis patients is primarily provided according to the degree of the patients' need for information.

    Psychoeducation is a key element in the management of patients with bipolar disorders. The present study explored the perception of patients and family members with respect to group psychoeducation for relatives. Patients (n = 20) and relatives (n = 26) were assessed with questionnaires about perceived benefits and quality of life (median 4 years after participation). A large majority (>80%) of relatives acknowledged benefits with respect to easier detection of the early warning signs of relapse, improved quality of life, feeling more involved, and engaging in higher quality caregiving activities. Patients were less positive in general, but agreed that the program had helped them deal with crises, increased their feeling of being understood by relatives, and promoted positive changes in the family (>60%). Perceived positive changes in the family were associated with higher quality of life for relatives and patients. The present study highlights the importance of communication enhancement in group psychoeducation for relatives. PMID:26313039

    Interstitial lung disease is the most common complication and cause of death among patients with scleroderma. Scleroderma-related interstitial lung disease has usually been treated with cyclophosphamide; however, its effect was evaluated to be modest and long-term administration of this drug is associated with adverse effects. Herein, we report our clinical experience of administering pirfenidone, which is an antifibrotic agent, in five patients with scleroderma-related interstitial lung disease. All patients demonstrated an increase in vital capacity.

    Increased intestinal permeability in patients with Crohn's disease and their first degree relatives has been proposed as an aetiological factor. The nine hour overnight urinary excretion of polyethyleneglycol-400 (PEG-400) and three inert sugars (lactulose, l-rhamnose, and mannitol) was used to test the permeation in 47 patients with Crohn's disease of whom 18 had at least one first degree relative with inflammatory bowel disease (2BD) and 52 patients with ulcerative colitis of whom 16 had at least one first degree relative with IBD. A total of 17 first degree relatives with IBD and 56 healthy first degree relatives were included. Thirty one healthy subjects not related to patients with IBD served as controls. No significant differences in PEG-400 permeation were found between the groups of patients, relatives, and controls, or between diseased and healthy relatives. The permeability to lactulose, rhamnose, and mannitol similarly did not differ between the three groups. This study challenges the previously reported findings of increased PEG-400 permeation in patients with Crohn's disease and in their healthy and diseased first degree relatives. There was no increase in permeability in a similar group of ulcerative colitis patients and their families. PMID:8307453

    Aharony, Bergman, Jafferis, and Maldacena have proposed that the low-energy description of multiple M2-branes at a Bbb C4/Bbb Zk singularity is a (2+1)-dimensional Script N = 6 supersymmetric U(Nc) × U(Nc) Chern-Simons matter theory, the ABJM theory. In the large-Nc limit, its holographic dual is supergravity in AdS4 × S7/Bbb Zk. We study various ways to add fields that transform in the fundamental representation of the gauge groups, i.e. flavor fields, to the ABJM theory. We work in a probe limit and perform analyses in both the supergravity and field theory descriptions. In the supergravity description we find a large class of supersymmetric embeddings of probe flavor branes. In the field theory description, we present a general method to determine the couplings of the flavor fields to the fields of the ABJM theory. We then study four examples in detail: codimension-zero Script N = 3 supersymmetric flavor, described in supergravity by Kaluza-Klein monopoles or D6-branes; codimension-one Script N = (0,6) supersymmetric chiral flavor, described by D8-branes; codimension-one Script N = (3,3) supersymmetric non-chiral flavor, described by M5/D4-branes; codimension-two Script N = 4 supersymmetric flavor, described by M2/D2-branes. Finally we discuss special physical equivalences between brane embeddings in M-theory, and their interpretation in the field theory description.

    2015-12-01

    This article contributes to sociological debates about trends in the power and status of medical professionals, focussing on claims that deferent patient relations are giving way to a more challenging consumerism. Analysing data from a mixed methods study involving general practitioners in England, we found some support for the idea that an apparent 'golden age' of patient deference is receding. Although not necessarily expressing nostalgia for such doctor-patient relationships, most GPs described experiencing disruptive or verbally abusive interactions at least occasionally and suggested that these were becoming more common. Younger doctors tended to rate patients as less respectful than their older colleagues but were also more likely to be egalitarian in attitude. Our data suggest that GPs, especially younger ones, tend towards a more informal yet limited engagement with their patients and with the communities in which they work. These new relations might be a basis for mutual respect between professionals and patients in the consulting room, but may also generate uncertainty and misunderstanding. Such shifts are understood through an Eliasian framework as the functional-democratisation of patient-doctor relations via civilising processes, but with this shift existing alongside decivilising tendencies involving growing social distance across broader social figurations.

    German psychiatrists actively engaged in the forced sterilization and killing of psychiatrically disabled children and adult patients. Academic psychiatrists embraced the Nazi philosophy and led the way in the "final solution" for psychiatric patients. This took place in a climate of widespread racism, virulent anti-Semitism, disillusionment with utopian social reforms, loss of medical confidentiality, devaluation of autonomy, intoxication with collectivism, injured national pride, and economic crisis. In this paper I review the impact on the physician-patient relationship of scientific, socio-economic, and political developments in the fifty years leading up to Hitler's rise to power, and explore potential implications for health care in the U.S.

All used texting for patient-related communication. Eleven percent of residents did not have a password on their cell phone and 89% did not have encrypted phones. Texting was the most common way (41%) by which residents communicated routine patient-related information with staff physicians. Most (85%) residents agreed that texting enhances patient care. The majority (66%) did not know if their hospital had a policy on texting and were unaware of legislation surrounding texting in patient care (89%). Conclusions Most general surgery residents use texting for communication of routine patient-related care issues. However, they acknowledge concerns regarding the security of this medium.

    We consider the application of twistor theory to five-dimensional anti-de Sitter space. The twistor space of AdS5 is the same as the ambitwistor space of the four-dimensional conformal boundary; the geometry of this correspondence is reviewed for both the bulk and boundary. A Penrose transform allows us to describe free bulk fields, with or without mass, in terms of data on twistor space. Explicit representatives for the bulk-to-boundary propagators of scalars and spinors are constructed, along with twistor action functionals for the free theories. Evaluating these twistor actions on bulk-to-boundary propagators is shown to produce the correct two-point functions.

    It was argued in [1] that the five-dimensional near-horizon extremal Kerr (NHEK) geometry can be embedded in String Theory as the infrared region of an infinite family of non-supersymmetric geometries that have D1, D5, momentum and KK monopole charges. We show that there exists a method to embed these geometries into asymptotically- {AdS}_3× {S}^3/{{Z}}_N solutions, and hence to obtain infinite families of flows whose infrared is NHEK. This indicates that the CFT dual to the NHEK geometry is the IR fixed point of a Renormalization Group flow from a known local UV CFT and opens the door to its explicit construction.

    The antagonistic effects between selenium (Se) and arsenic (As) suggest that low Se status plays an important role in arsenism development. The objective of present study was to assess Se contents in biological samples of As exposed females have skin lesions and cancer with related to non-exposed skin cancer patients. The biological samples (blood and scalp hair) of As exposed group comprises, female skin cancer (ESC) patients admitted in cancer hospitals have skin lesions (ESL) and exposed referents have not both diseases (ER), belongs to As exposed area of Pakistan. For comparative purposes, age matched female skin cancerous patient (RP) and non-cancerous females (NER) belong to non-exposed areas were also selected. The As and Se in acid digests of biological samples were pre-concentrated by complexing with chelating agent (ammonium pyrrolidinedithiocarbamate), and resulted complexes were extracted into non-ionic extractant (Triton X-114), prior to analysis by electrothermal atomic absorption spectrometry. The enhancement factor of about 25 was obtained by pre-concentrating 10 mL of sample solutions. The accuracy of the optimized procedure was evaluated by using certified reference material (BCR 397) with certified values for Se and As and standard addition method at three concentration levels in real samples. No significant differences was observed (p>0.05) when comparing the values obtained by the proposed method, added and certified values of both elements. The biological samples of ESC patients had 2-3 folds higher As and lower Se levels as compared to RP (p<0.001). Understudied exposed referents have high level of As and lower Se contents as compared to referents subjects of non-exposed area (p<0.01). The higher concentration of As and lower levels of Se in biological samples of cancerous patients are consisted with reported studies.

    Conformal totally symmetric arbitrary spin currents and shadow fields in flat space-time of dimension greater than or equal to four are studied. A gauge invariant formulation for such currents and shadow fields is developed. Gauge symmetries are realized by involving the Stueckelberg fields. A realization of global conformal boost symmetries is obtained. Gauge invariant differential constraints for currents and shadow fields are obtained. AdS/CFT correspondence for currents and shadow fields and the respective normalizable and non-normalizable solutions of massless totally symmetric arbitrary spin AdS fields are studied. The bulk fields are considered in a modified de Donder gauge that leads to decoupled equations of motion. We demonstrate that leftover on shell gauge symmetries of bulk fields correspond to gauge symmetries of boundary currents and shadow fields, while the modified de Donder gauge conditions for bulk fields correspond to differential constraints for boundary conformal currents and shadow fields. Breaking conformal symmetries, we find interrelations between the gauge invariant formulation of the currents and shadow fields, and the gauge invariant formulation of massive fields.

    Antibodies to nuclear antigens were assessed in 23 children with juvenile chronic arthritis (JCA) and 66 of their first degree relatives. Serum samples from 16 patients with JCA (70%) and nine relatives (14%) had antinuclear antibodies by indirect immunofluorescence. Antibodies against nuclear antigens in rabbit thymus extract or an erythroblastoid cell line (K562) were detected by countercurrent immunoelectrophoresis and immunoblotting in 16 patients (70%) and 39 family relatives (59%). Immunoblotting did not show any banding patterns common to all patients with JCA, though bands in the 43-45 kD range were detected in 5/23 patients. Anticardiolipin antibodies were found in 7/23 patients. In total, 18/20 families (90%) had members other than the probands with detectable autoantibodies. In five families immunoblotting showed common banding patterns between the probands and other members. This suggests that there might be an inherited trend towards autoimmune responses in some families of patients with JCA. PMID:2270968

    This study tested the hypothesis that muscle related temporomandibular disorder patients with cervical muscle pain exhibit greater degree of psychological distress compared with patients without cervical muscle pain and controls. Thirty-eight muscle related temporomandibular disorder patients including 10 patients with cervical muscle pain and 41 healthy individuals as controls participated in the study. State and trait anxiety levels were assessed with the Spielberger's state and trait anxiety inventory. Personality traits (extroversion, neuroticism, psychoticism and social desirability) were assessed using the Eysenck's personality questionnaire, and the pain intensities described over the muscles were recorded using a 100 mm visual analogue scale. The muscle related temporomandibular disorder patients, in general, exhibited significantly higher degrees of neuroticism and trait anxiety. The patients with cervical muscle pain demonstrated a significantly higher level of psychoticism compared with the patients without cervical muscle pain and the controls and a significantly higher state anxiety level than the controls. They also demonstrated higher pain intensities in masseter and temporalis muscles compared with patients without cervical muscle pain. It has been suggested that either subjects with psychological distress are prone to temporomandibular disorders, or psychological distress is a manifestation of existing chronic pain conditions. The present findings demand further investigations and broader approach in management, as muscle related temporomandibular disorder patients with cervical muscle pain were both physically and psychologically compromised to a greater degree compared with patients without cervical muscle pain.

    Ninety five patients receiving chronic haemodialysis (CHD) were surveyed to determine the prevalence of rheumatic disease and, where possible, its aetiology. At least three distinct rheumatic syndromes were identified--a group of patients with a syndrome consisting of large and medium joint synovial swelling, restricted hips and shoulders, tenosynovitis, carpal tunnel syndrome, and bone cysts due to deposition of beta 2 microglobulin related amyloid (AM beta 2m); a second group with erosive azotaemic osteoarthropathy; and a third group with age related degenerative disease of small, large, and axial joints. The data presented suggest that in patients receiving CHD (a) the prevalence of AM beta 2m deposition and the associated syndrome increases with duration of dialysis, but in patients who have been dialysed for more than 10 years the risk of developing AM beta 2m is related to age; (b) AM beta 2m deposition in subchondral cysts, but not synovium, causes joint destruction; also, AM beta 2m may be more prone to deposition in synovium of joints already damaged by other processes; (c) in the absence of synovial iron deposition synovial AM beta 2m is not associated with an inflammatory infiltrate; (d) hyperparathyroidism and perhaps other factors such as synovial iron deposition are probably more important than AM beta 2m as causes of peripheral joint degeneration and destructive spondyloarthropathy in patients receiving CHD.

    Purpose: The association between food insecurity and health-related quality of life (QOL) of racial/ethnic minority patients with cancer has not been examined. The purpose of this study is to determine the relationship between food insecurity and health-related QOL reported by racial/ethnic minority patients with cancer. Methods: A consecutive sample of 1,390 underserved ethnic minority patients receiving cancer care in 10 cancer clinics and hospitals in New York City participated in this study. Health-related QOL was measured by the Functional Assessment of Cancer Therapy-General (FACT-G) and food security was assessed by the US Department of Agriculture Core Food Security Module. Results: Of the 1,390 patients, 581 (41.8%) were classified as food secure, 571 (41.1%) with low food security, and 238 (17.1%) with very low food security. Health-related QOL decreased with each lower food security level. Patient self-reported physical, functional, social, and emotional well-being subscale scores decrease significantly with increasing food insecurity. After controlling for demographic and medical-related factors, the decreases in QOL, physical, functional, social and emotional well-being scores with increasing food insecurity remained significant. Conclusion: Food insecurity was associated with lower QOL in this sample of underserved racial/ethnic minority patients with cancer. Underserved ethnic minority patients diagnosed with cancer are a vulnerable patient population, at significant risk for inadequate food access and the related lower QOL. PMID:26286100

    The aim of this study was to describe the views of demented patients' relatives concerning the fulfillment of patients' rights in institutions. The Act on Patients' Rights and Status of March 1st, 1993, served as the basis for this study. Of the Act, the patients' rights to good care and treatment, to information and to self-determination were discussed. The data were collected from six medical wards for long-term patients at a hospital and from an old people's home by using a questionnaire. Ninety relatives of demented patients participated in the study, the response rate being 60%. The data were analyzed statistically. The relatives stated that the right to good care and treatment was realized best. The right to information was fulfilled quite well according to the respondents. The fact that the staff would not give information on their own initiative was regarded as lack of information. The right to self-determination was realized most poorly; 44% of the respondents could not say whether their relatives were able to affect the care with their opinions and wishes, and 59% could not answer whether the patient could reject the care. On the contrary, the respondents preferred their own right to influence decision-making concerning the care. Pensioners who answered the inquiry were more satisfied with the fulfillment of the patients' rights than others when the three rights were discussed. However, children as relatives were more dissatisfied than other relatives with the fulfillment of the right to information and self-determination.

    Purpose: Previous studies have reported a significant number of patients with breast cancer seek cancer-related information from the Internet. Most studies have asked whether a patient has ever read Internet information since her diagnosis. The purpose of this study was to assess the frequency with which patients with breast cancer come to physician appointments having recently read and intending to discuss cancer-related information from the Internet. Patients and Methods: We asked 558 patients with breast cancer who were waiting to see their physicians about their experiences reading cancer-related information from the Internet and their intent to discuss the information in their current visit. Results: Fifteen percent reported reading cancer-related Internet information in the past month. Patients who had read such information in the past month were younger, had been diagnosed more recently, and were more likely to be attending a new visit. Of those who had read in the past month, 45% reported intending to discuss what they had read with their physician. Nineteen percent of patients reported having ever read breast cancer–related Internet information since their diagnosis. Conclusion: The proportion of patients with breast cancer planning to discuss Internet information during their current physician visit was relatively small. Few characteristics were associated with recent Internet use or intent to discuss. PMID:22548010

    The aim of this study was to evaluate the efficacy and safety of ezetimibe 10 mg added to atorvastatin 20 mg compared with doubling atorvastatin to 40 mg in patients with hypercholesterolemia at moderately high risk for coronary heart disease who did not reach low-density lipoprotein (LDL) cholesterol levels <100 mg/dl with atorvastatin 20 mg. In this 6-week, multicenter, double-blind, randomized, parallel-group study, 196 patients treated with atorvastatin 20 mg received atorvastatin 20 mg plus ezetimibe 10 mg or atorvastatin 40 mg for 6 weeks. Adding ezetimibe 10 mg to atorvastatin 20 mg produced significantly greater reductions in LDL cholesterol than increasing atorvastatin to 40 mg (-31% vs -11%, p <0.001). Significantly greater reductions were also seen in non-high-density lipoprotein cholesterol, total cholesterol, and apolipoprotein B (p <0.001). Significantly more patients reached LDL cholesterol levels <100 mg/dl with atorvastatin 20 mg plus ezetimibe compared with atorvastatin 40 mg (84% vs 49%, p <0.001). The 2 treatment groups had comparable results for high-density lipoprotein cholesterol, triglycerides, apolipoprotein A-I, and high-sensitivity C-reactive protein. The incidences of clinical and laboratory adverse experiences were generally similar between groups. In conclusion, the addition of ezetimibe 10 mg to atorvastatin 20 mg was generally well tolerated and resulted in significantly greater lipid-lowering efficacy compared with doubling atorvastatin to 40 mg in patients with hypercholesterolemia at moderately high risk for coronary heart disease.

Objectives To determine effects of adding classification variables (McKenzie syndrome and pain patterns, including centralization and directional preference; Symptom Checklist Back Pain Prediction Model [SCL BPPM]; and the Fear-Avoidance Beliefs Questionnaire subscales of work and physical activity) to a baseline risk-adjusted model predicting functional status (FS) outcomes. Methods Consecutive patients completed a battery of questionnaires that gathered information on 11 risk-adjustment variables. Physical therapists trained in Mechanical Diagnosis and Therapy methods classified each patient by McKenzie syndromes and pain pattern. Functional status was assessed at discharge by patient-reported outcomes. Only patients with complete data were included. Risk of selection bias was assessed. Prediction of discharge FS was assessed using linear stepwise regression models, allowing 13 variables to enter the model. Significant variables were retained in subsequent models. Model power (R(2)) and beta coefficients for model variables were estimated. Results Two thousand sixty-six patients with lumbar impairments were evaluated. Of those, 994 (48%), 10 (<1%), and 601 (29%) were excluded due to incomplete psychosocial data, McKenzie classification data, and missing FS at discharge, respectively. The final sample for analyses was 723 (35%). Overall R(2) for the baseline prediction FS model was 0.40. Adding classification variables to the baseline model did not result in significant increases in R(2). McKenzie syndrome or pain pattern explained 2.8% and 3.0% of the variance, respectively. When pain pattern and SCL BPPM were added simultaneously, overall model R(2) increased to 0.44.

    Transition metals are cofactors for a wide range of vital enzymes and are directly or indirectly involved in the response against reactive oxygen species (ROS), which can damage cellular components. Their altered homeostasis has been studied in neurodegenerative disorders such as Alzheimer's disease (AD), Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS), but no data are available on rarer conditions. We aimed at studying the role of essential trace elements in ataxia telangiectasia (A-T), a rare form of pediatric autosomal recessive cerebellar ataxia with altered antioxidant response. We found an increased level of copper (Cu, p=0.0002) and a reduced level of zinc (Zn, p=0.0002) in the blood of patients (n. 16) compared to controls, using inductively coupled plasma mass spectrometry (ICP-MS). Other trace elements involved in the oxidative stress response, such as manganese (Mn) and selenium (Se), were unaltered. Cu/Zn-dependent superoxide dismutase (SOD1) was shown to have a 30% reduction in gene expression and 40% reduction in enzyme activity upon analysis of lymphoblastoid cell lines of patients (Student's t-test, p=0.0075). We also found a 30% reduction of Mn-SOD (SOD2; Student's t-test, p=0.02), probably due to a feedback regulatory loop between the two enzymes. The expression of antioxidant enzymes, such as erythrocyte glutathione peroxidase (GPX1), and SOD2 was unaltered, whereas catalase (CAT) was increased in A-T cells, both at the mRNA level and in terms of enzyme activity (~25%). Enhanced CAT expression can be attributed to the high ROS status, which induces CAT transcription. These results suggest that alterations in essential trace elements and their related enzymes may play a role in the pathogenesis of A-T, although we cannot conclude if altered homeostasis is a direct effect of A-T mutated genes (ATM). Altered homeostasis of trace elements may be more prevalent in neurodegenerative diseases than previously thought, and it may

    The role of oral bacteria in the development of chemotherapy-related oral mucositis has not been fully elucidated. This study aimed to investigate oral bacterial community diversity and dynamics in paediatric patients with malignancies in relation to the occurrence of oral mucositis. Patients with malignancies (n = 37) and reference individuals without known systemic disorders (n = 38) were recruited. For patients, oral bacterial samples were taken from mucosal surfaces both at the time of malignancy diagnosis and during chemotherapy. If oral mucositis occurred, samples were taken from the surface of the mucositis lesions. Oral mucosal bacterial samples were also taken from reference individuals. All samples were assessed using a 16S ribosomal RNA gene 454 pyrosequencing method. A lower microbial diversity (p < 0.01) and a higher intersubject variability (p < 0.001) were found in patients as compared with reference individuals. At the time of malignancy diagnosis (i.e. before chemotherapy) patients that later developed mucositis showed a higher microbial diversity (p < 0.05) and a higher intersubject variability (p < 0.001) compared with those without mucositis. The change of bacterial composition during chemotherapy was more pronounced in patients who later developed mucositis than those without mucositis (p < 0.01). In conclusion, we found a higher microbial diversity at the time of malignancy diagnosis in patients who later develop oral mucositis and that these patients had a more significant modification of the bacterial community by chemotherapy before the occurrence of mucositis. These findings may possibly be of clinical importance in developing better strategies for personalized preventive management. PMID:23829394

    Purpose Several studies have suggested that a combined approach of stress myocardial perfusion imaging (MPI) and coronary computed tomography angiography (CCTA) can provide diagnostic results with excellent accuracy. We aimed to explore whether the addition of CCTA to stress MPI provides incremental diagnostic value in intermediate-to-high cardiovascular risk patients. Methods A total of 106 consecutive patients (93 male, 65 ± 10.4 years) underwent coronary artery calcium scoring (CACS), CCTA and 201Thallium stress MPI before coronary angiography was reviewed. Thirty-seven patients (34.9%) had a history of proven coronary artery disease (CAD) or revascularization procedures, and four had documented non-significant CAD (3.8%). The remaining patients consisted of 17 (16.0%) classified as intermediate, and 48 (45.3%) as the high-risk groups. Results Obstructive CAD was diagnosed by invasive coronary angiography in 88 patients with 161 vessels. The sensitivity and specificity in a patient-based analysis for obstructive CAD were 99% and 17% for CCTA, 80% and 50% for MPI and 91% and 67% for the combined method, respectively. The per-vessel diagnostic sensitivity and specificity were 95% and 54% for CCTA, 59% and 75% for MPI and 84% and 76% for the combined method. There were significant differences (p < 0.05) when comparing the combined method with MPI or CCTA by areas under the curve in a patient- or vessel-based analysis. However, CACS of 400 or more could not further stratify the patients with obstructive CAD. Conclusions CCTA, not CACS, provided additional diagnostic values to stress MPI in patients with intermediate-to-high cardiovascular risk. PMID:27122945

    Ventilation/perfusion (V/P) single-photon emission computed tomography (SPECT) is recognized as a diagnostic method with potential beyond the diagnosis of pulmonary embolism. V/P SPECT identifies functional impairment in diseases such as heart failure (HF), pneumonia, and chronic obstructive pulmonary disease (COPD). The development of hybrid SPECT/computed tomography (CT) systems, combining functional with morphological imaging through the addition of low-dose CT (LDCT), may be useful in COPD, as these patients are prone to lung cancer and other comorbidities. The aim of this study was to investigate the added value of LDCT among healthy smokers and patients with stable COPD, when examined with V/P SPECT/CT hybrid imaging. Sixty-nine subjects, 55 with COPD (GOLD I-IV) and 14 apparently healthy smokers, were examined with V/P SPECT and LDCT hybrid imaging. Spirometry was used to verify COPD grade. Only one apparently healthy smoker and three COPD patients had a normal or nearly normal V/P SPECT. All other patients showed various degrees of airway obstruction, even when spirometry was normal. The same interpretation was reached on both modalities in 39% of the patients. LDCT made V/P SPECT interpretation more certain in 9% of the patients and, in 52%, LDCT provided additional diagnoses. LDCT better characterized the type of emphysema in 12 patients. In 19 cases, tumor-suspected changes were reported. Three of these 19 patients (ie, 4.3% of all subjects) were in the end confirmed to have lung cancer. The majority of LDCT findings were not regarded as clinically significant. V/P SPECT identified perfusion patterns consistent with decompensated left ventricular HF in 14 COPD patients. In 16 patients (23%), perfusion defects were observed.

    Ventilation/perfusion (V/P) single-photon emission computed tomography (SPECT) is recognized as a diagnostic method with potential beyond the diagnosis of pulmonary embolism. V/P SPECT identifies functional impairment in diseases such as heart failure (HF), pneumonia, and chronic obstructive pulmonary disease (COPD). The development of hybrid SPECT/computed tomography (CT) systems, combining functional with morphological imaging through the addition of low-dose CT (LDCT), may be useful in COPD, as these patients are prone to lung cancer and other comorbidities. The aim of this study was to investigate the added value of LDCT among healthy smokers and patients with stable COPD, when examined with V/P SPECT/CT hybrid imaging. Sixty-nine subjects, 55 with COPD (GOLD I-IV) and 14 apparently healthy smokers, were examined with V/P SPECT and LDCT hybrid imaging. Spirometry was used to verify COPD grade. Only one apparently healthy smoker and three COPD patients had a normal or nearly normal V/P SPECT. All other patients showed various degrees of airway obstruction, even when spirometry was normal. The same interpretation was reached on both modalities in 39% of the patients. LDCT made V/P SPECT interpretation more certain in 9% of the patients and, in 52%, LDCT provided additional diagnoses. LDCT better characterized the type of emphysema in 12 patients. In 19 cases, tumor-suspected changes were reported. Three of these 19 patients (ie, 4.3% of all subjects) were in the end confirmed to have lung cancer. The majority of LDCT findings were not regarded as clinically significant. V/P SPECT identified perfusion patterns consistent with decompensated left ventricular HF in 14 COPD patients. In 16 patients (23%), perfusion defects were observed. HF and perfusion defects were not recognized with LDCT. In COPD patients and long-time smokers, hybrid imaging had added value compared to V/P SPECT alone, by identifying patients with lung malignancy and more clearly identifying

    Patients diagnosed with bladder cancer may require a urinary diversion to maximize their health care outcomes. These patients, faced with sudden changes in their health status, develop complex unmet needs that can be addressed by a planned program of education. Peplau's theory of interpersonal relations offers a framework for patient teaching that emphasizes the importance of the nurse-patient relationship. This therapeutic relationship enables the nurse to provide the patient with the information needed to understand the diagnosis, cooperate in the treatment plan, facilitate postoperative recovery, and return to a state of independence with quality of life.

    PURPOSE: Massive earthquakes are harmful to humankind. This study of a historical cohort aimed to investigate the difference between earthquake-related crush thoracic traumas and thoracic traumas unrelated to earthquakes using a multi-detector Computed Tomography (CT). METHODS: We retrospectively compared an earthquake-exposed cohort of 215 thoracic trauma crush victims of the Sichuan earthquake to a cohort of 215 non-earthquake-related thoracic trauma patients, focusing on the lesions and coexisting injuries to the thoracic cage and the pulmonary parenchyma and pleura using a multi-detector CT. RESULTS: The incidence of rib fracture was elevated in the earthquake-exposed cohort (143 vs. 66 patients in the non-earthquake-exposed cohort, Risk Ratio (RR) = 2.2; p<0.001). Among these patients, those with more than 3 fractured ribs (106/143 vs. 41/66 patients, RR = 1.2; p<0.05) or flail chest (45/143 vs. 11/66 patients, RR = 1.9; p<0.05) were more frequently seen in the earthquake cohort. Earthquake-related crush injuries more frequently resulted in bilateral rib fractures (66/143 vs. 18/66 patients, RR = 1.7; p<0.01). Additionally, the incidence of non-rib fracture was higher in the earthquake cohort (85 vs. 60 patients, RR = 1.4; p<0.01). Pulmonary parenchymal and pleural injuries were more frequently seen in earthquake-related crush injuries (117 vs. 80 patients, RR = 1.5 for parenchymal and 146 vs. 74 patients, RR = 2.0 for pleural injuries; p<0.001). Non-rib fractures, pulmonary parenchymal and pleural injuries had significant positive correlation with rib fractures in these two cohorts. CONCLUSIONS: Thoracic crush traumas resulting from the earthquake were life threatening with a high incidence of bony thoracic fractures. The ribs were frequently involved in bilateral and severe types of fractures, which were accompanied by non-rib fractures, pulmonary parenchymal and pleural injuries. PMID:21789386

    Bortezomib-containing combinations are active in non-Hodgkin lymphoma (NHL) although peripheral neuropathy can limit their dose intensity. Based on our phase I findings, we conducted a phase II trial of bortezomib in combination with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) with a modified dose of vincristine. Patients with untreated indolent NHL received bortezomib (1·6 mg/m(2) ) on days 1 and 8 of a 21-day cycle for up to 8 cycles and R-CHOP with a 1·5 mg cap of vincristine. Patients achieving a complete response (CR) received maintenance rituximab, and remaining patients received maintenance rituximab and bortezomib. The primary endpoint was CR rate; secondary survival analyses were evaluated using the Kaplan-Meier method. Among 29 eligible patients, NHL morphologies included follicular (n = 20), marginal zone (n = 5) and small lymphocytic lymphoma (n = 4). Nineteen patients had CR (66%) and 10 had partial response (34%), yielding a 100% overall response rate. With a median follow-up of 48·7 months, the 4-year progression-free and overall survivals were 83% and 93%. Twenty-two patients experienced peripheral neuropathy of any grade, and two had grade 3 neuropathy. The combination of bortezomib with R-CHOP is effective for indolent NHL, and we plan to evaluate therapies incorporating novel proteasome inhibitors in future studies in NHL.

    Background: Health-related quality of life (HRQL) is an important patient-reported outcome for chronic obstructive pulmonary disease (COPD). Aim: We developed models predicting chronic respiratory questionnaire (CRQ) dyspnoea, fatigue, emotional function, mastery and overall HRQL at 6 and 24 months using predictors easily available in primary care. Methods: We used the “least absolute shrinkage and selection operator” (lasso) method to build the models and assessed their predictive performance. Results were displayed using nomograms. Results: For each domain-specific CRQ outcome, the corresponding score at baseline was the best predictor. Depending on the domain, these predictions could be improved by adding one to six other predictors, such as the other domain-specific CRQ scores, health status and depression score. To predict overall HRQL, fatigue and dyspnoea scores were the best predictors. Predicted and observed values were on average the same, indicating good calibration. Explained variance ranged from 0.23 to 0.58, indicating good discrimination. Conclusions: To predict COPD-specific HRQL in primary care COPD patients, previous HRQL was the best predictor in our models. Asking patients explicitly about dyspnoea, fatigue, depression and how they cope with COPD provides additional important information about future HRQL whereas FEV1 or other commonly used predictors add little to the prediction of HRQL.

    Celiac disease (CD) is a chronic autoimmune illness triggered by gluten consumption in genetically predisposed individuals. Worldwide, CD prevalence is approximately 1%. Several studies suggest a higher prevalence of undiagnosed CD in patients with infertility. We described reproductive disorders and assessed the frequency of hospital admissions for infertility among celiac women aged 15–49. We conducted two surveys enrolling a convenient sample of celiac women, residing in Apulia or in Basilicata (Italy). Moreover, we selected hospital discharge records (HDRs) of celiac women and women with an exemption for CD, and matched the lists with HDRs for reproductive disorders. In the surveys we included 91 celiac women; 61.5% of them reported menstrual cycle disorders. 47/91 reported at least one pregnancy and 70.2% of them reported problems during pregnancy. From the HDRs and the registry of exemption, we selected 4,070 women with CD; the proportion of women hospitalized for infertility was higher among celiac women than among resident women in childbearing age (1.2% versus 0.2%). Our findings highlight a higher prevalence of reproductive disorders among celiac women than in the general population suggesting that clinicians might consider testing for CD women presenting with pregnancy disorders or infertility.

    Environmental medicine outpatient clinics, counseling centers, and practicing physicians have observed environment-related health disorders in patient groups of mixed age as well as for groups consisting only of adults or children. Practicing physicians suspected correlations between environmental factors and health disorders in 36-45% of cases, environmental medicine outpatient clinics and counseling centers in 4-34% for mixed-age groups, 0-24% for adults, and 9-13% for children. A comparison of these data is difficult due to differences in data acquisition, evaluation methods, and descriptive statistics used. Furthermore, data on children are insufficient. Patient-oriented environmental medicine faces a number of problems regarding determination of exposure, effects, and susceptibility, including a lack of scientifically verified cause-and-effect models as well as incorrect diagnoses, attributions, and conclusions. In view of the scope and intensity of environment-related health disorders, the topic cannot be ignored. A functioning program of environmental medicine counseling and patient care is needed for practicing physicians, universities and/or the public sector to deliver effective primary medical care in this field. As always, the building blocks of environ-mental medicine counseling are medical history, physical examination, differential diagnosis, human biomonitoring, and on-site inspection with environmental monitoring while also taking gender differences into account. Uniform basic documentation procedures and health science analyses will help to optimize patient care in environ-mental medicine. The value of a diagnostic algorithm in the care of patients with environment-related health disorders is beyond dispute. Last but not least, quality assurance and control are a sine qua non of patient-oriented environmental medicine. PMID:15340722

    The purpose of the present study was to compare differences in physiological outcomes and health-related quality of life (HRQOL) in relation to degree of illness in patients with chronic heart failure (CHF) and to compare HRQOL in CHF patients with that of a normal Japanese population. One hundred and twenty-five patients with stable CHF (93 men, 32 women, mean age 63.3 ± 12.4 years) with left ventricular ejection fraction (LVEF) of less than 40% were enrolled in the present study. We used New York Heart Association (NYHA) functional class as an index of degree of illness. In 64 of the 125 patients, physiological outcome measures included peak oxygen uptake (peak O2) and E/CO2 slope. HRQOL was assessed with the medical outcome study short form-36 (SF-36) Japanese version. In addition, SF-36 scores of CHF patients were compared against Japanese standard values. Age and LVEF did not differ according to NYHA functional class. The eight SF-36 subscale scores and peak O2 decreased with increases in the NYHA functional classes, whereas E/CO2 slope increased with increases in NYHA functional class (p<0.05). Of the 8 SF-36 subscales measured in CHF patients, only the bodily pain score attained that of the normal Japanese population. These findings suggest that HRQOL decreases as NYHA functional class increases and other physiological measures worsen. In addition, HRQOL values of CHF patients were low in comparison with standard values of a normal Japanese population. PMID:25792942

    Zolpidem-induced sleep-related complex behaviors (SRCB) with anterograde amnesia have been reported. We describe herein a case in which the development of zolpidem-induced sleep-related eating disorder (SRED) and SRCB was strongly suspected. A 71-year-old Korean male was admitted to the Department of Psychiatry due to his repetitive SRED and SRCB with anterograde amnesia, which he reported as having occurred since taking zolpidem. The patient also had restless legs syndrome (RLS) and obstructive sleep apnea (OSA). His baseline serum iron level was low at admission. Zolpidem discontinuation resulted in the immediate disappearance of his SRED, but did not affect his RLS symptoms. These symptoms rapidly improved after adding a single i.v. iron injection once daily, and so he was discharged to day-clinic treatment. These findings indicate that zolpidem can induce SRCB. Although the pathophysiology of zolpidem-induced SRED and other SRCB remains unclear, clinicians should carefully monitor for the potential induction of complex behaviors associated with zolpidem in patients with comorbid RLS or OSA.

    Plasmodium vivax is the world's most widely distributed malaria parasite and a potential cause of morbidity and mortality for approximately 2.85 billion people living mainly in Southeast Asia and Latin America. Despite this dramatic burden, very few vaccines have been assessed in humans. The clinically relevant vectors modified vaccinia virus Ankara (MVA) and the chimpanzee adenovirus ChAd63 are promising delivery systems for malaria vaccines due to their safety profiles and proven ability to induce protective immune responses against Plasmodium falciparum thrombospondin-related anonymous protein (TRAP) in clinical trials. Here, we describe the development of new recombinant ChAd63 and MVA vectors expressing P. vivax TRAP (PvTRAP) and show their ability to induce high antibody titers and T cell responses in mice. In addition, we report a novel way of assessing the efficacy of new candidate vaccines against P. vivax using a fully infectious transgenic Plasmodium berghei parasite expressing P. vivax TRAP to allow studies of vaccine efficacy and protective mechanisms in rodents. Using this model, we found that both CD8+ T cells and antibodies mediated protection against malaria using virus-vectored vaccines. Our data indicate that ChAd63 and MVA expressing PvTRAP are good preerythrocytic-stage vaccine candidates with potential for future clinical application.

    In 2013, the Canadian Armed Forces (CAF) implemented the Fitness for Operational Requirements of Canadian Armed Forces Employment (FORCE), a field expedient fitness test designed to predict the physical requirements of completing common military tasks. Given that attaining this minimal physical fitness standard may not represent a challenge to some personnel, a fitness incentive program was requested by the chain of command to recognize and reward fitness over and above the minimal standard. At the same time, it was determined that the CAF would benefit from a measure of general health-related fitness, in addition to this measure of operational fitness. The resulting incentive program structure is based on gender and 8 age categories. The results on the 4 elements of the FORCE evaluation were converted to a point scale from which normative scores were derived, where the median score corresponds to the bronze level, and silver, gold, and platinum correspond to a score which is 1, 2, and 3 SDs above this median, respectively. A suite of rewards including merit board point toward promotions and recognition on the uniform and material rewards was developed. A separate group rewards program was also tabled, to recognize achievements in fitness at the unit level. For general fitness, oxygen capacity was derived from FORCE evaluation results and combined with a measure of abdominal circumference. Fitness categories were determined based on relative risks of mortality and morbidity for each age and gender group. Pilot testing of this entire program was performed with 624 participants to assess participants' reactions to the enhanced test, and also to verify logistical aspects of the electronic data capture, calculation, and transfer system. The newly dubbed fitness profile program was subsequently approved by the senior leadership of the CAF and is scheduled to begin a phased implementation in June 2015.

    PubMed

    2016-01-01

    Pediatric patients with Down syndrome (DS) are at an increased risk of developing certain cancers. Specifically, patients with DS have a reported 10-20-fold increased risk of developing acute myeloid leukemia (AML). Anthracycline-based treatment regimens achieve good results in patients with DS and AML. It has been proposed that DS status constitutes a risk factor for the cardiotoxicity associated with the use of anthracyclines in the pediatric setting. However, published evidence pointing toward an increased risk of cardiotoxicity in patients with DS is relatively scarce and conflictive. This concise review compiles literature relating to the incidence of anthracycline-related cardiotoxicity in pediatric patients with DS. In general, reports from trials using anthracyclines at the maximum recommended dose showed increases in the incidence of anthracycline-related cardiotoxicity in patients with DS in comparison with trials that used anthracyclines at reduced doses. Evidence from the literature suggests that patients with DS can achieve favorable therapeutic outcomes after receiving treatment with reduced doses of anthracyclines to minimize the potential for cardiotoxicity. Further prospective trials, along with the available evidence, would assist the design of treatment protocols for patients with pediatric leukemias and DS.

    The present study examined the association of denture quality and health-related quality of life (HRQoL) in patients with removable dentures. In a study of 171 consecutive patients with removable partial dentures or complete dentures (mean age: 68·0 ± 9·3 years) at a university-based prosthodontic clinic, dentists rated two aspects of denture quality (stability and aesthetics) using a 100-mm visual analog scale (VAS). HRQoL was evaluated using the mental and physical component summary (MCS and PCS) scores of the Medical Outcomes Study Short-Form 36-Item Health Survey (SF-36). Oral health-related quality of life (OHRQoL) was evaluated using the Oral Health Impact Profile-Japanese version (OHIP-J). The associations among denture quality, OHRQoL, and HRQoL were examined by linear regression models. Bivariable linear regression analyses revealed that denture stability was significantly associated with the SF-36 MCS [regression coefficient = 0·52 for a 10-unit increase in denture stability on a 0-100 VAS, 95% confidence interval (CI): 0·03-1·00, P = 0·04], but not with the PCS (0·11, 95% CI: -0·49 to 0·70). Denture aesthetics was not related to the PCS or the MCS (0·22, 95% CI: -0·44 to 0·88 or 0·07, 95%CI: -0·47 to 0·62). When OHIP-J was added to the regression model, this variable was substantially and significantly associated with the MCS and PCS summary scores; in addition, the regression coefficient for denture quality decreased in magnitude and was statistically nonsignificant in all analyses. The quality of removable dentures had a minimal effect on HRQoL in patients with removable dentures, and this association was mediated by OHRQoL.

    Clinical studies have shown that negative symptoms of schizophrenia unresponsive to antipsychotic given alone can improve after augmentation with SSRI antidepressant. Laboratory investigations into the mechanism of this synergism showed that co-administration of SSRI and antipsychotic produces changes in GABA(A) receptor and related systems, which differ from the effects of each drug alone. To examine the clinical relevance of these findings, the current study examined the effects of SSRI augmentation treatment on GABA(A) receptor and related systems in schizophrenia patients. Schizophrenia patients with high levels of negative symptoms unresponsive to antipsychotic treatment received add-on fluvoxamine (100 mg/d). Blood was taken before and 1, 3 and 6 wk after adding fluvoxamine and peripheral mononuclear cells (PMC) isolated. RNA encoding for GABA(A)β3, 5-HT2A, and 5-HT7 receptors, PKCβ2, and brain-derived neurotrophic factor (BDNF) was assayed with real-time RT-PCR. Plasma BDNF protein was assayed using ELISA. Clinical symptoms were assessed with validated rating scales. We found significant increase in mRNA encoding for GABA(A)β3 and 5-HT2A, 5-HT7 receptors and BDNF and a reduction in PKCβ2 mRNA. Plasma BDNF protein concentrations were increased. There were significant correlations among the genes. Clinical symptoms improved significantly. mRNA expression of PKCβ2, 5-HT2A and 5-HT7 showed significant associations with clinical symptoms. Combined SSRI+antipsychotic treatment is associated with changes in GABA(A) receptor and in related signalling systems in patients. These changes may be part of the mechanism of clinically effective drug action and may prove to be biomarkers of pharmacological response.

    A reconstruction of the position of the North Pacific Jet Stream (NPJ) in wintertime over the past 500 years is. Reconstruction of NPJ behavior is driven by an analog process that employs existing paleoclimate field reconstructions of winter temperature, summer precipitation and summer soil moisture from western North America to select climate model states in millennial climate simulations that are closest to the field reconstructions. The skill of the reconstruction method is tested against the 20CR meteorological reanalysis. All three types of proxy sets individually contribute to the skill in the reconstruction of the winter atmospheric circulation. The NPJ reconstruction is also evaluated in relation to dry and wet extremes in California and extremes of Sierra Nevada fire activity. Results indicate that fire and precipitation extremes are both closely linked with NPJ winter position, with characteristic wet/low fire and dry/high fire NPJ spatial features in the northeastern Pacific adjacent to western North America. The meridional profiles of zonal wind at 200 hPa height can be classified according to winters belonging to dry and wet hydrological years and also according to summers with high or low fire activity. This classification indicates that in wet years and low-fire years the jet stream is more intense, more zonally oriented with peak winds occurring at lower latitudes. The opposite configuration occurs in dry, high-fire, years, with a more meandering jet stream peaking at higher latitudes. These features are in turn evaluated in future climate model scenarios using directly comparable transient integrations that cover the past millennium, the instrumental period, and the 21st century. Relatively wet/low fire regional conditions are reasonably possible in the later 21st century under a high greenhouse gas forcing regime (RCP 8.5), even though temperatures rise significantly. The implication of this combination of conditions in the Sierra Nevada is that

    In this study we studied the effects of particulate matter samples (PM) through gene expression analysis in a routine air quality monitoring campaign by the Flemish Environment Agency (VMM, Belgium). We selected a human hepatoma (HepG2) multiple endpoint reporter assay for targeted stress related endpoint screening. Organic extracts of air samples (total suspended particles, TSP) were collected during one year in an industrial, urban and background location in Flanders, Belgium. Simultaneously, meteorological conditions (temperature, wind speed and precipitation) and particulate matter size ≤ 10 μM (PM10), organic (OC), elemental (EC) and total (TC) carbon were monitored and air samples were collected for chemical analysis (11 PAHs). Correlations between the induction of the different stress genes and the chemical pollutants were analysed. Exposure of HepG2 cells to daily air equivalents (20 m3) of organic TSP extracts revealed the dominant induction of the xenobiotic response element (Xre) and phase I (Cyp1A1) and phase II (GstYa) biotransformation enzymes. Additional effects were the induction of c-Fos, a proto-oncogen and Gadd45, a marker for cell cycle disturbance and responsive to genotoxic compounds. Inductions of other relevant pathways, such as sequestration of heavy metals, retinoids response, protein misfolding and increased cAMP levels were measured occasionally. A significant correlation was found between the genes Cyp1A1 (a typical marker for presence of PAHs and dioxin like compounds), c-Fos, Gadd45, (responsive to DNA damaging compounds) and the amount of PM10 and elemental carbon (EC) whereas no correlation was found between these genes and total PAHs content. This may suggest that the observed induction of Cyp1A1 and DNA damage related genes was provoked (partially) by other particle bound compounds (e.g. pesticides, PCBs, brominated flame retardants, dioxins, …), than PAHs. The contribution of particle bound compounds, other than PAHs might

  4. Transforming Trauma: The Relational Unconscious and "Chemistry" in the Treatment of a Paraplegic Patient.

    Therapeutic action with a traumatized paraplegic patient highlights the evocative-and transformative-influence of the relational unconscious. The patient's triumphant resolution suggests that formative bipersonal dynamics (including transference, countertransference, and mutual projective identifications) create an ongoing intersubjective enactment and relational chemistry pivotal to psychic shift. A broad systems perspective highlights contextual communication and the interweaving of the analyst's etiological contributions and subjective experience of trauma. Ultimately, an unconscious, co-created dynamic challenges traumatic fixations, supporting a reintegration of narcissistic, gender, and erotic representations and ego capacities. An eclectic perspective that illuminates the analyst's role-receptivity encompasses classical, object relations, relational, systems, and self psychological paradigms.

    Structure-based sequence alignment is an essential step in assessing and analysing the relationship of distantly related proteins. PASS2 is a database that records such alignments for protein domain superfamilies and has been constantly updated periodically. This update of the PASS2 version, named as PASS2.5, directly corresponds to the SCOPe 2.04 release. All SCOPe structural domains that share less than 40% sequence identity, as defined by the ASTRAL compendium of protein structures, are included. The current version includes 1977 superfamilies and has been assembled utilizing the structure-based sequence alignment protocol. Such an alignment is obtained initially through MATT, followed by a refinement through the COMPARER program. The JOY program has been used for structural annotations of such alignments. In this update, we have automated the protocol and focused on inclusion of new features such as mapping of GO terms, absolutely conserved residues among the domains in a superfamily and inclusion of PDBs, that are absent in SCOPe 2.04, using the HMM profiles from the alignments of the superfamily members and are provided as a separate list. We have also implemented a more user-friendly manner of data presentation and options for downloading more features. PASS2.5 version is available at http://caps.ncbs.res.in/pass2/. PMID:26553811

    Coeliac disease (CD) is an immune-mediated enteropathy resulting from exposure to gluten in genetically predisposed individuals. Gluten proteins are partially digested by human proteases generating immunogenic peptides that cause inflammation in patients carrying HLA-DQ2 and DQ8 genes. Although intestinal dysbiosis has been associated with patients with CD, bacterial metabolism of gluten has not been studied in depth thus far. The aim of this study was to analyse the metabolic activity of intestinal bacteria associated with gluten intake in healthy individuals, CD patients and first-degree relatives of CD patients. Faecal samples belonging to twenty-two untreated CD patients, twenty treated CD patients, sixteen healthy volunteers on normal diet, eleven healthy volunteers on gluten-free diet (GFD), seventy-one relatives of CD patients on normal diet and sixty-nine relatives on GFD were tested for several proteolytic activities, cultivable bacteria involved in gluten metabolism, SCFA and the amount of gluten in faeces. We detected faecal peptidasic activity against the gluten-derived peptide 33-mer. CD patients showed differences in faecal glutenasic activity (FGA), faecal tryptic activity (FTA), SCFA and faecal gluten content with respect to healthy volunteers. Alterations in specific bacterial groups metabolising gluten such as Clostridium or Lactobacillus were reported in CD patients. Relatives showed similar parameters to CD patients (SCFA) and healthy volunteers (FTA and FGA). Our data support the fact that commensal microbial activity is an important factor in the metabolism of gluten proteins and that this activity is altered in CD patients.

  9. Is there an added clinical value of "true"whole body(18)F-FDG PET/CT imaging in patients with malignant melanoma?

    Accurate and reliable staging of disease extent in patients with malignant MM is essential to ensure appropriate treatment planning. The detection of recurrent or residual malignancy after primary treatment is important to allow for early intervention and to optimise patient survival. 2-deoxy-2-[(18)F]fluoro-D-glucose ((18)F-FDG) PET or PET computed tomography (PET/CT) is indicated for surveillance of malignant MM due to its high sensitivity and specificity for soft-tissue or nodal recurrences and metastases. It has been claimed that including lower extremities and skull in addition to 'eyes to thigh' images in PET/CT evaluation of metastatic MM routinely is warranted. We have studied retrospectively the reports of whole-body PET/CT scans in all patients with MM scanned in our Department from April 2005 to December 2010. All PET abnormalities in the brain/scalp and lower extremities were tabulated by location and whether they were 'expected' or 'unexpected'. Findings were correlated with pathology, other imaging studies, and clinical follow-up. In this study, 398 PET/CT examinations in 361 patients with MM were included. Results showed that twelve of the 398 (3%) scans had brain/scalp abnormalities, with only 4 (1.0%) showing unexpected abnormalities. Twenty nine of the 398 (7.2%) scans showed lower extremity abnormalities, with only 5 (1.2%) showing unexpected abnormalities. In no case was an isolated unexpected malignant lesion identified in the brain/scalp or lower extremities. In conclusion, whole body PET/CT scan showed about 1% unexpected primary or metastatic MM lesions involving the head or lower extremities, which seldom offered significant additional clinical benefit and were unlikely to change clinical management. No clinically significant change in staging would have occurred. Routine 'eyes to thighs' images were adequate for this subset of patients. PMID:23106051

    Objectives Medical history, physical examination and laboratory testing are not optimal for the assessment of volume status in heart failure (HF) patients. We aimed to study the clinical influence of focused ultrasound of the pleural cavities and inferior vena cava (IVC) performed by specialised nurses to assess volume status in HF patients at an outpatient clinic. Methods HF outpatients were prospectively included and underwent laboratory testing, history recording and clinical examination by two nurses with and without an ultrasound examination of the pleural cavities and IVC using a pocket-size imaging device, in random order. Each nurse worked in a team with a cardiologist. The influence of the different diagnostic tests on diuretic dosing was assessed descriptively and in linear regression analyses. Results Sixty-two patients were included and 119 examinations were performed. Mean±SD age was 74±12 years, EF was 34±14%, and N-terminal pro-brain natriuretic peptide (NT-proBNP) value was 3761±3072 ng/L. Dosing of diuretics differed between the teams in 31 out of 119 consultations. Weight change and volume status assessed clinically with and without ultrasound predicted dose adjustment of diuretics at follow-up (p<0.05). Change of oedema, NT-proBNP, creatinine, and symptoms did not (p≥0.10). In adjusted analyses, only volume status based on ultrasound predicted dose adjustments of diuretics at first visit and follow-up (all ultrasound p≤0.01, all other p≥0.2). Conclusions Ultrasound examinations of the pleural cavities and IVC by nurses may improve diagnostics and patient care in HF patients at an outpatient clinic, but more studies are needed to determine whether these examinations have an impact on clinical outcomes.

    A survey of 70 insightful clinically stable out-patients with functional psychotic disorders and 70 accompanying relatives was carried out. They were interviewed about their beliefs concerning the cause of the illness, and their awareness of other possible aetiological factors. Relevant sociodemographic and clinical information were also elicited. Twelve (17.1%) patients and relatives, respectively, gave "medical" causal explanations; 16 (22.9%) patients and 13 (18.6%) relatives gave "psychosocial" causal explanations; 27 (38.6%) patients and 38 (54.3%) relatives were "uncertain" about the cause of their/relatives' illness (X2 = 5.08; df = 3: P = 0.16). Relatives reported a greater relevance of "heredity" (X2 = 11.58; P = 0.0006) and "supernatural" factors (X2 = 4.72: P = 0.029) as other possible causal factors, than patients. Patients with previous psychiatric hospitalisation reported higher prevalence of "psychosocial" and "supernatural" causal beliefs than those without (X2 = 9.15; P = 0.027). Also, patients with "medical" causal belief reported better treatment compliance than those with other beliefs (P = 0.031). Among relatives, "psychosocial" causal belief in comparison with other beliefs was associated with a longer duration of treatment in the hospital (h = 8.29; P = 0.04). For patients, knowledge about possible causal role of "heredity was significantly more prevalent among male than female patients (X2 = 6.55; P = 0.01) and admission of possible "supernatural" causation was associated with education below the secondary level (X2 = 6.68; P = 0.008). For relatives, knowledge about possible causal role of brain dysfunction was associated with longer duration of treatment (u = 3.93; P = 0.047), and knowledge of possible causal role of "psychosocial" stress was associated with urban place of residence rather than rural (X2 = 10.52; P = 0.0012). For both patients and relatives, the most acceptable aetiological proposition was the "supernatural" while the least

    Few clinical studies have focused on the efficacy of lipid-lowering therapies in patients > or = 65 years of age. The percentage of change from baseline in low-density lipoprotein (LDL) cholesterol and the percentage of patients achieving prespecified LDL cholesterol levels after 12 weeks of ezetimibe 10 mg plus atorvastatin versus up titration of atorvastatin were assessed in subjects > or = 65 years old with hyperlipidemia and at high risk of coronary heart disease. After stabilization of atorvastatin 10-mg therapy, 1,053 patients, > or = 65 years old, at high risk of coronary heart disease, with and without atherosclerotic vascular disease and a LDL cholesterol level that was not <70 or <100 mg/dl, respectively, were randomized to receive ezetimibe added to atorvastatin 10 mg for 12 weeks versus up titration to atorvastatin 20 mg for 6 weeks followed by up titration to atorvastatin 40 mg for an additional 6 weeks. Ezetimibe added to atorvastatin 10 mg resulted in significantly greater changes at week 6 in LDL cholesterol (p <0.001), significantly more patients with atherosclerotic vascular disease achieving a LDL cholesterol level of <70 mg/dl (p <0.001), and significantly more patients without atherosclerotic vascular disease achieving a LDL cholesterol level of <100 mg/dl (p <0.001) at weeks 6 and 12 compared to atorvastatin 20 mg or atorvastatin 40 mg. In addition, ezetimibe plus atorvastatin 10 mg resulted in significantly greater changes at week 6 in total cholesterol, triglycerides, non-high-density lipoprotein (HDL) cholesterol, apolipoprotein B (all p <0.001), and HDL cholesterol (p = 0.021) compared with atorvastatin 20 mg and significantly greater changes at week 12 in LDL cholesterol, non-HDL cholesterol, apolipoprotein A-I (p = 0.001), total cholesterol, apolipoprotein B (p <0.030), and HDL cholesterol (p <0.001) compared with atorvastatin 40 mg.

    Objective To identify and stratify the main stressors for the relatives of patients admitted to the adult intensive care unit of a teaching hospital. Methods Cross-sectional descriptive study conducted with relatives of patients admitted to an intensive care unit from April to October 2014. The following materials were used: a questionnaire containing identification information and demographic data of the relatives, clinical data of the patients, and 25 stressors adapted from the Intensive Care Unit Environmental Stressor Scale. The degree of stress caused by each factor was determined on a scale of values from 1 to 4. The stressors were ranked based on the average score obtained. Results The main cause of admission to the intensive care unit was clinical in 36 (52.2%) cases. The main stressors were the patient being in a state of coma (3.15 ± 1.23), the patient being unable to speak (3.15 ± 1.20), and the reason for admission (3.00 ± 1.27). After removing the 27 (39.1%) coma patients from the analysis, the main stressors for the relatives were the reason for admission (2.75 ± 1.354), seeing the patient in the intensive care unit (2.51 ± 1.227), and the patient being unable to speak (2.50 ± 1.269). Conclusion Difficulties in communication and in the relationship with the patient admitted to the intensive care unit were identified as the main stressors by their relatives, with the state of coma being predominant. By contrast, the environment, work routines, and relationship between the relatives and intensive care unit team had the least impact as stressors. PMID:27737424

    A phase IV, multicentre, randomized, double-blind, parallel-group, comparative study was conducted in Japanese subjects with type 2 diabetes mellitus (T2DM) who had inadequate glycaemic control, despite treatment with alogliptin in addition to diet and/or exercise therapy. Subjects with glycated haemoglobin (HbA1c) concentrations of 6.9-10.5% were randomized to receive 16 weeks' double-blind treatment with pioglitazone 15 mg, 30 mg once daily or placebo added to alogliptin 25 mg once daily. The primary endpoint was the change in HbA1c from baseline at the end of treatment period (week 16). Both pioglitazone 15 and 30 mg combination therapy resulted in a significantly greater reduction in HbA1c than alogliptin monotherapy [-0.80 and -0.90% vs 0.00% (the least squares mean using analysis of covariance model); p < 0.0001, respectively]. The overall incidence rates of treatment-emergent adverse events were similar among the treatment groups. Pioglitazone/alogliptin combination therapy was effective and generally well tolerated in Japanese subjects with T2DM and is considered to be useful in clinical settings.

    Background Ulcerative colitis (UC) impairs the health-related quality of life (HRQOL). The difference in HRQOL between patients with mild and moderately active UC is not well-defined. Few studies have been conducted to explore the factors that influence HRQOL in Chinese patients. Our study aims were to (1) compare HRQOL of mildly active UC patients with moderate patients; (2) explore the factors that influence HRQOL in Chinese patients with UC; and (3) analyze demographic and disease characteristics of UC in China. Methods A total of 110 mild and 114 moderate patients with UC were enrolled. The demographic and disease characteristics were recorded. HRQOL was measured by the Chinese version of the inflammatory bowel disease questionnaire (IBDQ) between mild and moderate patients, male and female patients, and different disease distributions. Stepwise regression analysis was used to assess factors influencing the IBDQ score. Results Patients with moderate UC had significantly lower IBDQ total scores compared to patients with mild UC (P=0.001). The IBDQ total score had a negative correlation with the Mayo score (r=–0.263, P<0.001). Stepwise regression analysis showed that the disease activity index and gender had an influence on the IBDQ total score (P<0.05). The female patients had a lower score than the male patients (P<0.05), especially in the emotional function domain (P=0.002). Different disease distributions were not statistically significant in the IBDQ total score (P=0.183). Conclusions UC has a negative influence on HRQOL. HRQOL in patients with moderate UC was lower than HRQOL in patients with mild UC, as measured by the IBDQ. UC disease activity has a negative correlation with HRQOL. Gender and the disease activity index are important factors involved in the impairment of HRQOL in Chinese patients with UC. Chinese females may benefit from increased psychological care as part of UC therapy. PMID:25915777

    Borderline personality disorder (BPD) is determined by the presence of any five of nine diagnostic criteria, leading patients with heterogeneous clinical features to be diagnosed under the same label without an individualized clinical and therapeutic approach. In response to this problem, Oldham proposed five types of BPD: affective, impulsive, aggressive, dependent and empty. The present study categorized a sample of BPD patients hospitalized due to suicide-related behavior according to Oldham's BPD proposed subtypes, and evaluated their clinical and demographic characteristics. Data were obtained from a sample of 93 female patients admitted to the « Dr. Braulio A. Moyano » Neuropsychiatric Hospital following suicide-related behavior. A total of 87 patients were classified as affective (26%), impulsive (37%), aggressive (4%), dependent (29%), and empty (5%). Patients classified as dependent were significantly older at the time of first suicide-related behavior (p = 0.0008) and reported significantly less events of previous suicide-related behaviors (p = 0.03), while patients classified as impulsive reported significantly higher rates of drug use (p = 0.02). Dependent, impulsive and affective BPD types were observed most frequently in our sample. Findings are discussed specific to demographic and clinical implications of BPD patients reporting concurrent suicidal behavior.

    ABSTRACT Approximately 30% of patients treated with ipilimumab will develop gastrointestinal toxicity. The immunological drivers that underpin the clinical observations in human tissues are poorly understood. We report here on the immune consequences of ipilimumab treatment in the colorectal mucosa of patients with treatment-related colitis. Using immunohistochemistry, we evaluated the immune infiltrate by CD8+, FoxP3, and granzyme B (GzmB) in colonic biopsies from 20 patients with ipilimumab-related colitis. We assessed 10 cases with normal colon biopsies for comparison. In eight cases (four on steroids only, four on steroids and infliximab), we evaluated two sequential biopsies. We observed that CD8+, FoxP3+, and GzmB T cell counts were significantly higher in patients with ipilimumab-related colitis compared to normal colon (p < 0.0001). Patients who required infliximab for the resolution of their colitis had a significantly higher CD8+/FoxP3 ratio than those treated only with steroids and this correlated with clinical severity. The analysis of repeat samples revealed that resolution of the colitis was associated with a decrease in CD8+ and FoxP3+ cells both in patients treated with steroids and infliximab. Our data suggest that counts of cytotoxic T cells and Tregs in the colonic mucosa from patients with ipilimumab-related colitis correlate with clinical findings and may predict severity and guide management.

    Increasing data suggests that there is a connection between stress and the appearance of psoriasis symptoms. We therefore performed a clinical trial enrolling 40 participants who were randomly allocated to either an 8-week cognitive-behavioural therapy (CBT) (treatment group) plus narrow-band UVB phototherapy or to an 8-week course of only narrow-band UVB phototherapy (control group). We evaluated the clinical severity of psoriasis (PASI), General Health Questionnaire (GHQ)-12, Skindex-29 and State-Trait Anxiety Inventory (STAI) at baseline and by the end of the study. Sixty-five percent of patients in the treatment group achieved PASI75 compared with 15% of standard UVB patients (p = 0.007). GHQ-12 cases were reduced from 45% to 10% in the treatment group and from 30% to 20% in the control group (p = 0.05). The Skindex-29 emotional domain showed a significant improvement in the CBT/biofeedback group compared with control patients (-2.8 points, p = 0.04). This study shows that an adjunctive 8-week intervention with CBT combined with biofeedback increases the beneficial effect of UVB therapy in the overall management of psoriasis, reduces the clinical severity of psoriasis, improving quality of life and decreases the number of minor psychiatric disorders.

    Endothelial dysfunction appears to be an early sign indicating vascular damage and predicts the progression of atherosclerosis and cardiovascular disorders. Extensive clinical and experimental evidence suggests that endothelial dysfunction occurs in Type 2 Diabetes Mellitus (T2DM) and prediabetes patients. This study was carried out with an aim to appraise the expression levels in the peripheral blood of 84 genes related to endothelial cells biology in patients with diagnosed T2DM or prediabetes, trying to identify new genes whose expression might be changed under these pathological conditions. The study covered a total of 45 participants. The participants were divided into three groups: group 1, patients with T2DM; group 2, patients with prediabetes; group 3, control group. The gene expression analysis was performed using the Endothelial Cell Biology RT2 Profiler PCR Array. In the case of T2DM, 59 genes were found to be upregulated, and four genes were observed to be downregulated. In prediabetes patients, increased expression was observed for 49 genes, with two downregulated genes observed. Our results indicate that diabetic and prediabetic conditions change the expression levels of genes related to endothelial cells biology and, consequently, may increase the risk for occurrence of endothelial dysfunction.

    The aim of the present investigation was to assess the psychological profile of a sample of patients with temporomandibular disorders (TMD) and to compare the psychometric scores between patients with pain of different diffusion, location, intensity and duration. One hundred and ten (N = 110) patients with painful TMD fulfilled three psychometric instruments. Pain features were assessed as categorical variables as concerns its diffusion, viz., diffuse or localised, duration, viz., more or <6 months, and location, viz., joint and/or muscles. Pain intensity was scored on a 0-100 Visual Analog Scale (VAS) rating. Patients with diffuse pain showed higher psychometric scores than patients with localised pain. No significant differences were detected between patients with pain lasting from more or equal than 6 months and those with pain lasting from <6 months as well as between patients with pain localised in the jaw muscles, joints or both, even if a trend for lower scores for patients with joint pain alone was observed. Pain intensity was significantly related with anxiety (ANX), depression (DEP) and somatisation(SOM) scores. In conclusion, pain diffusion and intensity were strongly related with high levels of SOM, ANX and DEP, while no differences in psychometric scores were detected between patients with pain of different duration and location.

    Previous research has not considered the influence of the Comorbid Mental Disorder (CMD) among Substance Use Disorders (SUD) patients. We explored the possible differences in personality dimensions among SUD patients taking into account their CMD (Schizophrenia, SZ; Bipolar Disorder, BD; Major Depressive Disorder, MDD); and elucidated clinical factors related to personality dimensions according to the CMD. The Temperament and Character Inventory Revised was used to assess a sample of 102 SUD male patients, considered in three groups according to their CMD: SUD+SZ (N=37), SUD+BD (N=30) and SUD+MDD (N=35). SUD+BD patients had the highest levels of Novelty Seeking and Persistence, SUD+SZ patients showed the highest levels of Harm Avoidance, and SUD+MDD patients reported a lower level of Self-transcendence. Novelty Seeking was positively associated with severity of addiction for SUD+BD; Harm Avoidance was positively associated with psychiatric symptoms for SUD+SZ; and the age of SUD onset was positively linked to Cooperativeness for SUD+BD and to Self-transcendence for SUD+MDD. The different personality characteristics associated to the type of CMD among SUD patients are related to several clinical variables. Interventions in these patients should be tailored according the personality traits that could influence treatment outcomes and patients' prognoses.

    Our aim was to measure the adherence to Artemisinin based Combination Therapy and to determine patient related factors that affect adherence. Three hundred (300) patients receiving ACT treatment dispensed from the community pharmacy were randomly selected and followed up on the fourth day after the start of their three-day therapy to assess adherence. Adherence was measured by pill count. Quantitative interviews using a semistructured questionnaire were used to assess patients' knowledge and beliefs on malaria and its treatment. Adherence levels to the ACTs were 57.3%. Patient related factors that affected adherence to ACTs were patients' knowledge on the dosage (P = 0.007; v = 0.457), efficacy (P = 0.009; v = 0.377), and side effects (P = 0.000; v = 0.403) of the ACTs used for the management of malaria, patients' awareness of the consequences of not completing the doses of antimalarial dispensed (P = 0.001; v = 0.309), and patients' belief that “natural remedies are safer than medicines” and “prescribers place too much trust in medicines.” There was no significant relationship between adherence and patients' knowledge on the causes, signs, and symptoms of malaria. There is the need for pharmacy staff to stress on these variables when counseling patients on antimalarials as these affect adherence levels. PMID:25767736

    Chronic illness stigma is a global public health issue. Most widely studied in HIV/AIDS and mental illness, stigmatization of patients living with inflammatory bowel disease (IBD), chronic autoimmune conditions affecting the digestive tract, has garnered increasing attention in recent years. In this paper, we systematically review the scientific literature on stigma as it relates to IBD across its three domains: perception, internalization, and discrimination experiences. We aim to document the current state of research, identify gaps in our knowledge, recognize unique challenges that IBD patients may face as they relate to stigmatization, and offer suggestions for future research directions. Based on the current review, patients living with IBD may encounter stigmatization and this may, in turn, impact several patient outcomes including quality of life, psychological functioning, and treatment adherence. Significant gaps exist related to the understanding of IBD stigma, providing opportunity for future studies to address this important public health issue. PMID:27022294

    Malnutrition and small intestinal bacterial overgrowth (SIBO) is frequently present in patients with liver cirrhosis (LC). However, the direct relationship between SIBO and nutrition status in the LC patients has not been elucidated. The aim of this study was to investigate whether there was an association between nutrition status, evaluated by the subjective global assessment (SGA) and SIBO in patients with Hepatitis B virus (HBV) or hepatitis C virus (HCV) related cirrhosis. A total of 120 patients with HBV or HCV-related cirrhosis and 30 healthy controls were included. Nutritional status was determined according to SGA and anthropometry. All patients and healthy controls underwent a glucose hydrogen breath test for SIBO. The prevalence of malnutrition for the patients with HBV or HCV related cirrhosis ranged 19.4%-60% in China. The highest prevalence of malnutrition was detected by SGA, the lowest by triceps skinfold thickness. The frequency of SIBO was significantly higher in the malnourished (SGA-B/C) than in the well-nourished (SGA-A) patients with HBV or HCV related cirrhosis [41/72 (56.9%) vs 12/48 (25.0%) (p=0.001)]. Univariate analysis showed that SIBO, ascites, and Child-Turcotte-Pugh (CTP) class were associated with malnutrition. Multivariate analysis demonstrated that SIBO [odds ratio (OR) 8.10; p=0.002] and ascites (OR 4.56; p=0.022) were independently associated with the occurrence of malnutrition (SGA-B/C) in the same subjects. SIBO is independently related to the occurrence of malnutrition (SGA-B/C) in patients with HBV or HCV cirrhosis. We deduce that SIBO may play an important role in nutrition status in patients with HBV or HCV cirrhosis.

    The glutamatergic system is a key point in pathogenesis of schizophrenia. Sarcosine (N-methylglycine) is an exogenous amino acid that acts as a glycine transporter inhibitor. It modulates glutamatergic transmission by increasing glycine concentration around NMDA (N-methyl-d-aspartate) receptors. In patients with schizophrenia, the function of the glutamatergic system in the prefrontal cortex is impaired, which may promote negative and cognitive symptoms. Proton nuclear magnetic resonance (1H-NMR) spectroscopy is a non-invasive imaging method enabling the evaluation of brain metabolite concentration, which can be applied to assess pharmacologically induced changes. The aim of the study was to evaluate the influence of a six-month course of sarcosine therapy on the concentration of metabolites (NAA, N-acetylaspartate; Glx, complex of glutamate, glutamine and γ-aminobutyric acid (GABA); mI, myo-inositol; Cr, creatine; Cho, choline) in the left dorso-lateral prefrontal cortex (DLPFC) in patients with stable schizophrenia. Fifty patients with schizophrenia, treated with constant antipsychotics doses, in stable clinical condition were randomly assigned to administration of sarcosine (25 patients) or placebo (25 patients) for six months. Metabolite concentrations in DLPFC were assessed with 1.5 Tesla 1H-NMR spectroscopy. Clinical symptoms were evaluated with the Positive and Negative Syndrome Scale (PANSS). The first spectroscopy revealed no differences in metabolite concentrations between groups. After six months, NAA/Cho, mI/Cr and mI/Cho ratios in the left DLPFC were significantly higher in the sarcosine than the placebo group. In the sarcosine group, NAA/Cr, NAA/Cho, mI/Cr, mI/Cho ratios also significantly increased compared to baseline values. In the placebo group, only the NAA/Cr ratio increased. The addition of sarcosine to antipsychotic therapy for six months increased markers of neurons viability (NAA) and neurogilal activity (mI) with simultaneous improvement

    Single nucleotide polymorphisms in PICALM, a key component of clathrin-mediated endocytosis machinery, have been identified as genetic susceptibility loci for late onset Alzheimer's disease (LOAD). We previously reported that PICALM protein levels were decreased in AD brains and that PICALM was co-localised with neurofibrillary tangles in LOAD, familial AD with PSEN1 mutations and Down syndrome. In the present study, we analysed PICALM expression, cell localisation and association with pathological cellular inclusions in other tauopathies and in non-tau related neurodegenerative diseases. We observed that PICALM was associated with neuronal tau pathology in Pick disease and in progressive supranuclear palsy (PSP) and co-localised with both 3R and 4R tau positive inclusions unlike in corticobasal degeneration (CBD) or in frontotemporal lobar degeneration (FTLD)-MAPT P301L. PICALM immunoreactivities were not detected in tau-positive tufted astrocytes in PSP, astrocytic plaques in CBD, Lewy bodies in Lewy body disease, diffuse type (LBD) and in TDP-43-positive inclusions in FTLD. In the frontal cortex in tauopathies, the ratio of insoluble to soluble PICALM was increased while the level of soluble PICALM was decreased and was inversely correlated with the level of phosphotau. PICALM decrease was also significantly correlated with increased LC3-II and decreased Beclin-1 levels in tauopathies and in non-tau related neurodegenerative diseases. These results suggest that there is a close relationship between abnormal PICALM processing, tau pathology and impairment of autophagy in human neurodegenerative diseases.

    Background: Using drugs is a common affliction in patients with Schizophrenia affecting their increasing death rate. They have to tolerate longer treatment time and staying in hospital and they further show more violence and their living quality decreases. It also seems that this factor is among the influential factors of unsuccessful results in treating these patients. Objectives: Despite all this, there is little data about drug consumption, psychopathology and demographic information in patients with chronic schizophrenia in Iran. This paper reviews the relation between drug consumption and the mentioned qualities in patients afflicted by chronic Schizophrenia. Methods: In this cross-sectional study, 100 patients with Schizophrenia were interviewed based on DSM-IV-TR diagnostic parameters and according to a psychiatrist´s views. The severity of psychopathology was evaluated, using PANSS, (SCID-I) DSM-IV and BARRAT. Results: The results show that in patients with chronic schizophrenia, there is a meaningful relation between cigarette consumption and education, gender, family background and BARRAT. It also has a direct correlation with Attention and Motor. Drug consumption has a meaningful relation with gender and Motor (p< 0.05). But it has no relation with BARRAT. Of the variables having a relation with correlation, cigarette and treatment period factors have a predicting effect for drug consumption. Conclusions: According to the results, drug and cigarette consumption is high among patients with Chronic Schizophrenia. Common cigarette consumption and its relation with impulsiveness increase, and death rate are the reasons which make us take the needed steps to have these patients quit smoking. PMID:26153213

    Gastric dysmotility has been reported in patients suffering from major depression or schizophrenia. An increased sympathetic activity modulating the gastric pacemaker located in the antrum of the stomach has been suggested as the underlying pathology. Similar to patients suffering from schizophrenia, their first-degree relatives showed alterations in cardiac autonomic modulation. Here we aimed to investigate gastric myoelectrical activity in healthy relatives of patients suffering from paranoid schizophrenia. Electrogastrography (EGG) was performed before and after test meal ingestion in 20 patients with paranoid schizophrenia, 20 of their first-degree relatives and 20 healthy matched controls. Autonomic and abdominal symptoms were assessed by the autonomic symptom score as previously reported. Autonomic parameters were correlated with the positive and negative syndrome scale (PANSS). Only minimal differences were observed before test meal ingestion between relatives and controls. In contrast, after test meal ingestion we observed a significantly increased tachygastria within the signal of the gastric pacemaker in relatives compared to controls, whereas normogastria was reduced. Significant difference between relatives and controls were also found for postprandial ICDF (instability coefficient of dominant frequency) and slow wave, which represents the dominant frequency of gastric pacemaker activity, indicating gastric dysmotility in relatives. Between relatives and patients just a difference for ICDP (instability coefficient of dominant power) was observed. After stimulation of the enteric nervous system we have observed an increased sympathetic modulation in first-degree relatives of patients suffering from schizophrenia. This result adds evidence to an ongoing debate on the genetic influence of autonomic dysfunction in the disease. PMID:20654673

    Patients with medication-related osteonecrosis of the jaw (MRONJ) are at risk for developing infections and often require long-term antimicrobial therapy for management. It is unclear whether patients with multiple myeloma (MM) who develop MRONJ experience increased morbidity when they undergo hematopoietic cell transplantation (HCT). The aim of this study was to characterize the course of HCT in MM patients with MRONJ. A retrospective chart review was conducted for patients with MM and MRONJ who underwent HCT between December 2005 and December 2014. Data collected included bisphosphonate use, MRONJ stage, positive blood cultures, number of febrile days, and length of hospital stay. Eleven patients (median age, 61; range, 46 to 71) fulfilled the criteria. Patients received zoledronic acid (72.7%), pamidronate (18.1%), or a combination of both (9%). At the time of HCT, 10 patients were in stage 1 MRONJ with 1 in stage 0. All patients had only mandibular involvement. No patient developed pain/infection at the MRONJ site during hospitalization. Bacteremia with positive blood cultures for Staphylococcus aureus occurred in 3 patients (27.2%), and 4 patients (36.3%) developed fever lasting between 4 to 6 days (of who 1 had positive blood cultures). The median length of hospital stay was 17 days (range, 7 to 22 days). These data suggests that patients with MM and MRONJ who undergo HCT are not at increased risk of developing symptoms associated with the MRONJ site or HCT-related infectious complications, and their MRONJ is not worsened by HCT.

    The aim of the study was to evaluate of patients satisfaction in relation to private or public health care provider in the Warsaw's (capital of Poland) region. The authors have used original (partially psychometric test) tool named "Skala AB". 590 adult patients were randomly chosen from 20 private and public owned clinics and hospitals. Main outcome of the study was that patients of private owned clinics (but working on contract with general health insurance system) are much more satisfied from the services provided by these clinics than patients treated by local government-owned clinics. In general patients treated in hospitals were more satisfied than patients treated in clinics. Comparison of more detailed determinants of satisfaction, has shown that all health service facilities in study region, in their practices do not consider the "concentration on real needs of patients" as a serious matter and this is the reason of patients dissatisfaction. Level of satisfaction from the services provided by health care facilities did not correlate with gender or age of the respondents. In opposite, the (higher) level of education and place of living (in a big city) have negatively correlated with patients satisfaction. The tool ("Skala AB") used in this survey was found very convenient for evaluation of the patients satisfaction of services provided by health care facilities. PMID:15002261

    There has been sustained international interest from health care policy makers, practitioners, and researchers in developing interprofessional approaches to delivering patient-centred care. In this paper, we offer a critical exploration of a selection of professional discourses related to these practice paradigms, including interprofessional collaboration, patient-centred care, and the combination of the two. We argue that for some groups of patients, inequalities between different health and social care professions and between professionals and patients challenge the successful realization of the positive aims associated with these discourses. Specifically, we argue that interprofessional and professional-patient hierarchies raise a number of key questions about the nature of professions, their relationships with one another as well as their relationship with patients. We explore how the focus on interprofessional collaboration and patient-centred care have the potential to reinforce a patient compliance model by shifting responsibility to patients to do the "right thing" and by extending the reach of medical power across other groups of professionals. Our goal is to stimulate debate that leads to enhanced practice opportunities for health professionals and improved care for patients. PMID:25180630

  14. Efficacy of adding the kinesio taping method to guideline-endorsed conventional physiotherapy in patients with chronic nonspecific low back pain: a randomised controlled trial

    PubMed Central

    2013-01-01

    Background Chronic nonspecific low back pain is a significant health condition with high prevalence worldwide and it is associated with enormous costs to society. Clinical practice guidelines show that many interventions are available to treat patients with chronic low back pain, but the vast majority of these interventions have a modest effect in reducing pain and disability. An intervention that has been widespread in recent years is the use of elastic bandages called Kinesio Taping. Although Kinesio Taping has been used extensively in clinical practice, current evidence does not support the use of this intervention; however these conclusions are based on a small number of underpowered studies. Therefore, questions remain about the effectiveness of the Kinesio Taping method as an additional treatment to interventions, such as conventional physiotherapy, that have already been recommended by the current clinical practice guidelines in robust and high-quality randomised controlled trials. We aim to determine the effectiveness of the addition of the use of Kinesio Taping in patients with chronic nonspecific low back pain who receive guideline-endorsed conventional physiotherapy. Methods/design One hundred and forty-eight patients will be randomly allocated to receive either conventional physiotherapy, which consists of a combination of manual therapy techniques, general exercises, and specific stabilisation exercises (Guideline-Endorsed Conventional Physiotherapy Group) or to receive conventional physiotherapy with the addition of Kinesio Taping to the lumbar spine (Conventional Physiotherapy plus Kinesio Taping Group) over a period of 5 weeks (10 sessions of treatment). Clinical outcomes (pain intensity, disability and global perceived effect) will be collected at baseline and at 5 weeks, 3 months, and 6 months after randomisation. We will also collect satisfaction with care and adverse effects after treatment. Data will be collected by a blinded assessor. All

    This work evaluates the radiological risk that patients treated with I for differentiated thyroid cancer could present to relatives and occupationally exposed workers. Recently, the International Atomic Energy Agency issued document K9010241, which recommends that patient discharge from the hospital must be based on the particular status of each patient. This work measures effective dose received by caregivers of patients treated with I at the Instituto Nacional de Cancerología, Mexico City. Thermoluminescent dosimeters were carried during a 15-d period by 40 family caregivers after patient release from hospital. Relatives were classified into two groups, ambulatory and hospitalized, according to the release mode of the patient, and three categories according to the individual patient home and transport facilities. Categories A, B, and C were defined going from most to least adequate concerning public exposure risk. Measurements were performed for 20 family caregivers in each group. The effective dose received by all caregivers participating in this study was found to be less than 5 mSv, the recommended limit per event for caregivers suggested by ICRP 103. In addition, 70 and 90% of ambulatory and hospitalized groups, respectively, received doses lower than 1 mSv. Caregivers belonging to category C, with home situations that are not appropriate for immediate release, received the highest average doses; i.e., 2.2 ± 1.3 and 3.1 ± 1.0 mSv for hospitalized and ambulatory patients, respectively. Results of this work have shown that the proper implementation of radiation protection instructions for relatives and patients can reduce significantly the risk that differentiated thyroid cancer patients treated with I can represent for surrounding individuals. The results also stress the relevance of the patient's particular lifestyle and transport conditions as the prevailing factors related to the dose received by the caregiver. Therefore, the patient's status should be

  16. Holography beyond conformal invariance and AdS isometry?

    Barvinsky, A. O.

    2015-03-15

    We suggest that the principle of holographic duality be extended beyond conformal invariance and AdS isometry. Such an extension is based on a special relation between functional determinants of the operators acting in the bulk and on its boundary, provided that the boundary operator represents the inverse propagators of the theory induced on the boundary by the Dirichlet boundary value problem in the bulk spacetime. This relation holds for operators of a general spin-tensor structure on generic manifolds with boundaries irrespective of their background geometry and conformal invariance, and it apparently underlies numerous O(N{sup 0}) tests of the AdS/CFT correspondence, based on direct calculation of the bulk and boundary partition functions, Casimir energies, and conformal anomalies. The generalized holographic duality is discussed within the concept of the “double-trace” deformation of the boundary theory, which is responsible in the case of large-N CFT coupled to the tower of higher-spin gauge fields for the renormalization group flow between infrared and ultraviolet fixed points. Potential extension of this method beyond the one-loop order is also briefly discussed.

    OBJECTIVE: To assess the health related quality of life and psychological wellbeing of patients with hypertrophic cardiomyopathy, to correlate these with symptoms, clinical, and psychosocial factors. DESIGN: Questionnaire distributed to 171 hypertrophic cardiomyopathy patients aged at least 14 years, selected at random from a dataset of 480 patients. Assessments included the Short Form 36 (SF-36) Health Survey, the Hospital Anxiety and Depression questionnaire, and measures of adjustment, worry, and patient satisfaction. RESULTS: There was an 80.1% response rate to the questionnaire. Patients had severe limitations in all eight dimensions of quality of life assessed by the SF-36: physical functioning, role limitations owing to physical problems, role limitations owing to emotional problems, social functioning, mental health, general health perceptions, vitality, and bodily pain. Levels of anxiety and depression were also high compared with population norms. Quality of life was particularly impaired in patients with chest pain and dyspnoea, but was less consistently related to clinical cardiological measures. Adjustment to the condition and patient satisfaction were generally good. In multivariate analysis, quality of life was associated with a combination of symptom patterns and psychosocial factors. No differences in quality of life, anxiety or depression were observed between patients with no known family history, those with familial cardiomyopathy, and patients with a family history of premature sudden death. CONCLUSIONS: Hypertrophic cardiomyopathy is associated with substantial restrictions in health related quality of life. Symptoms, adjustment, and quality of interactions with clinical staff contribute to these limitations. Recognition of the problems confronted by patients with hypertrophic cardiomyopathy requires continued efforts at education both of the public and health professionals. PMID:9326995

    The burden imposed by disease recurrence in patients with high-grade gliomas is not well documented. We studied the frequency of self-report symptoms and the effects on health-related quality of life in patients who had recurrent glioblastoma multiforme or anaplastic astrocytoma and who had a Karnofsky performance score > or = 70. Patients completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 Items (QLQ-C30) and the Brain Cancer Module (BCM20) before initiation of treatment for first recurrence of disease. Six symptoms (fatigue, uncertainty about the future, motor difficulties, drowsiness, communication difficulties, and headache) were reported with a frequency > 50% by both groups of patients. An additional two symptoms (visual problems and pain) were also reported with frequencies of > 50% by patients with recurrent glioblastoma multiforme. Most of the symptoms were likely due to recurrence, but previous radiation therapy and on-going corticosteroid treatment may have also been casual factors for fatigue, whereas uncertainty about the future and pain were probably nonspecific for brain cancer. Problems with motor functioning, vision, leg strength, and pain were reported more frequently by patients with recurrent glioblastoma multiforme than by those with recurrent anaplastic astrocytoma. Scores on health-related quality-of-life functioning scales were similar in the two groups. Finally, the scores for patients who had recurrent high-grade gliomas and a Karnofsky performance score > or = 70 were compared with the reported health-related quality of life scores of patients with other cancers. Their scores were similar to those of patients with metastatic cancers and worse than those of patients with localized cancers. PMID:11265231

    Cancer patients and relatives worldwide are turning more and more to the internet to obtain health information. The goal of this survey was to clarify their experiences and suggestions on the implementation of information and communication technology (ICT) in oncology. A total of 127 patients and 60 relatives visiting the outpatient clinic at the Department of Oncology, University of North Norway (UNN), the regional office of the Norwegian Cancer Union (NCU) and the Montebello Centre were included in a questionnaire-based study. Participants were recruited during the period September 2001 to February 2002. There were 92 women and 95 men. We revealed that hospital doctors, followed by nurses and friends, were the most important informants. Two-thirds of patients and relatives had access to the internet, but fewer than one-third had searched the internet for medical information and only one-fifth had discussed information accessed with their doctor. Only one-tenth had visited a hospital website. Internet access was correlated with young age. Almost two-thirds suggested that e-mail and/or WAP (wireless application protocol) communication should be included in hospital-patient communication. Concerning hospital websites, waiting time, treatment offer and addresses were considered the top three topics of interest. In conclusion, the majority of cancer patients and relatives have access to the internet. They recommend ICT employed in patient-hospital communication and suggest waiting time, treatment offers and addresses the three most important topics on hospital websites.

    The aim of this study was to evaluate event-related potentials (ERP) and cognition in multiple sclerosis (MS) patients with regard to fatigue and disease-related variables. The study comprised 86 MS patients and 40 controls. Fatigue was assessed using the Fatigue Severity Scale (FSS/FSS-5) and the Modified Fatigue Impact Scale (MFIS/MFISmod). N200 and P300 components of auditory ERP were analyzed. Cognition was evaluated by means of Brief Repeatable Battery of Neuropsychological Tests (BRBNT). The results of ERP and BRBNT were compared between non-fatigued, moderately and severely fatigued MS patients and controls. P300 latency was significantly longer in the whole MS group and in the fatigued patients than in the controls. A positive correlation was found between P300 latency and MFIS/MFISmod results, independent from age and MS-related variables. The fatigued patients scored less than non-fatigued ones in tests evaluating memory, visuomotor abilities and attention. Results of these tests correlated significantly with fatigue measures, independently from MS-related variables. Fatigue in MS patients showed significant relationships with impairment within the memory and attention domains. Parameters of auditory ERP, as electrophysiological biomarkers of cognitive performance, were not independently linked to fatigue.

    Patients with melanoma who had one or more close relatives with melanoma were studied for their natural-killer-cell (NK) activity against cultured melanoma cells and Chang cells. A high proportion of the patients and their relatives were found to have low NK activity against these target cells. In most of the patients this could not be attributed to general depression of their immune function, since B- and T-cell numbers and the mitogenic response to PHA were within normal limits. The levels of NK activity of the patients and their relatives were found to be significantly correlated, suggesting that the NK activity in these families may have been genetically (or environmentally) determined. Several genetic markers were examined in the patients and their relatives for association with the disease state and NK activity. No association with HLA antigens or ABO blood groups was detected, but there was a low incidence of the Rhesus negative phenotype in the patients (the Rh phenotype had previously been associated with high NK activity). The present results indicate that NK activity has a familial association in families with a high incidence of melanoma, and raise the question whether low NK activity may be one of the predisposing factors in the development of familial melanoma.

The case-control study included a group of cancer patients and a matched group of healthy controls: 57 cancer patients and 41 healthy controls living in Stari Grad (an urban area of Belgrade), as well as 17 cancer patients and 13 healthy controls living in Barajevo (a rural community in the vicinity of Belgrade). The healthy controls were matched to cancer patients in sex and age; they were not blood related. The selenium serum levels were measured by atomic absorption spectrophotometry. Health-related habits and relevant dietary factors ("food frequency" method) that may influence the selenium serum levels were assessed by questionnaires. The differences in average values of selenium serum levels between the cancer patients and healthy controls were not significantly different, but both were below the lowest recorded in referential studies. A significant difference between the values obtained from urban and rural subgroups was noted. The most important factors that influenced the level of selenium included the residence place in the region with selenium deficiency (Barajevo), age, associated chronic diseases, and some dietary factors potentially related to the intake of selenium. The results obtained in this investigation pointed out that use of selenium supplementation in this area should be seriously considered.

    Non-invasive EEG-based Brain-Computer Interfaces (BCI) can be promising for the motor neuro-rehabilitation of paraplegic patients. However, this shall require detailed knowledge of the abnormalities in the EEG signatures of paraplegic patients. The association of abnormalities in different subgroups of patients and their relation to the sensorimotor integration are relevant for the design, implementation and use of BCI systems in patient populations. This study explores the patterns of abnormalities of movement related cortical potentials (MRCP) during motor imagery tasks of feet and right hand in patients with paraplegia (including the subgroups with/without central neuropathic pain (CNP) and complete/incomplete injury patients) and the level of distinctiveness of abnormalities in these groups using pattern classification. The most notable observed abnormalities were the amplified execution negativity and its slower rebound in the patient group. The potential underlying mechanisms behind these changes and other minor dissimilarities in patients' subgroups, as well as the relevance to BCI applications, are discussed. The findings are of interest from a neurological perspective as well as for BCI-assisted neuro-rehabilitation and therapy.

    Close relatives of persons with dementia self-reported reactions on the Anticipatory Grief Scale (AGS), were observed by nurses (Study I), and compared with relatives of cancer patients in a study using the same methodology (Study II). Study I showed an overall stressful situation including feelings of missing and longing, inability to accept the terminal fact, preoccupation with the ill, tearfulness, sleeping problems, anger, loneliness, and a need to talk. The ability to cope was, however, reported high. Self-assessments and nurses' observations did not always converge, e.g. for the acceptance of the illness. The reactions of the relatives in the dementia and the cancer groups showed more similarities than dissimilarities. However, the higher number of responding spouses in the cancer group may have influenced the outcome. PMID:22495791

    INTRODUCTION. Treatment modalities for end-stage renal disease affect quality of life (QOL) of the patients. This study was conducted to assess the QOL of patients on hemodialysis and compare it with caregivers of these patients. Cause of ESRD and dialysis-related factors affecting QOL were also examined. MATERIALS AND METHODS. This cross-sectional study was conducted on patient on maintenance hemodialysis for more than 3 months at 3 dialysis centers of Lahore. Fifty healthy individuals were included as controls from among the patients' caregivers. The QOL index was measured using the World Health Organization QOL questionnaire, with higher scores corresponding to better QOL of patients. RESULTS. Eighty-nine patients (71.2%) were men, 99 (79.2%) were married, 75 (60.0%) were older than 45 years, and 77 (61.6%) were on dialysis for more than 8 months. Patients on hemodialysis had a poorer QOL as compared to their caregivers in all domains except for domain 4 (environment). There was no difference in the QOL between the three dialysis centers of the study, except for domain 3 (social relationship) of the patients at Mayo Hospital (a public hospital), which was significantly better. Nondiabetic patients had a better QOL in domain 1 (physical health) as compared to diabetic patients. Duration of dialysis had a reverse correlation with the overall QOL. CONCLUSIONS. We found that QOL of hemodialysis patients was poor as compared to caregivers of the patients, especially that of diabetics. Also, duration of dialysis had a reverse correlation with QOL.

    Patient-provider relationships influence diabetes care; less is known about their impact on online patient portal use. Diabetes patients rated provider communication and trust. In this study, we linked responses to electronic medical record data on being a registered portal user and using secure messaging (SM). We specified regression models to evaluate main effects on portal use, and subgroup analyses by race/ethnicity and age. 52% of subjects were registered users; among those, 36% used SM. Those reporting greater trust were more likely to be registered users (relative  risk (RR)=1.14) or SM users (RR=1.29). In subgroup analyses, increased trust was associated with being a registered user among white, Latino, and older patients, as well as SM use among white patients. Better communication ratings were also related to being a registered user among older patients. Since increased trust and communication were associated with portal use within subgroups, this suggests that patient-provider relationships encourage portal engagement.

    Although there is a consensus that patients with schizophrenia have certain deficits in perceiving and expressing facial emotions, previous studies of facial emotion perception in schizophrenia do not present consistent results. The objective of this study was to explore facial emotion perception deficits in Chinese patients with schizophrenia and their non-psychotic first-degree relatives. Sixty-nine patients with schizophrenia, 56 of their first-degree relatives (33 parents and 23 siblings), and 92 healthy controls (67 younger healthy controls matched to the patients and siblings, and 25 older healthy controls matched to the parents) completed a set of facial emotion perception tasks, including facial emotion discrimination, identification, intensity, valence, and corresponding face identification tasks. The results demonstrated that patients with schizophrenia performed significantly worse than their siblings and younger healthy controls in accuracy in a variety of facial emotion perception tasks, whereas the siblings of the patients performed as well as the corresponding younger healthy controls in all of the facial emotion perception tasks. Patients with schizophrenia also showed significantly reduced speed than younger healthy controls, while siblings of patients did not demonstrate significant differences with both patients and younger healthy controls in speed. Meanwhile, we also found that parents of the schizophrenia patients performed significantly worse than the corresponding older healthy controls in accuracy in terms of facial emotion identification, valence, and the composite index of the facial discrimination, identification, intensity and valence tasks. Moreover, no significant differences were found between the parents of patients and older healthy controls in speed after controlling the years of education and IQ. Taken together, the results suggest that facial emotion perception deficits may serve as potential endophenotypes for schizophrenia.

    Urea cycle defects are a group of metabolic disorders caused by enzymatic disruption of the urea cycle pathway, transforming nitrogen to urea for excretion from the body. Severe cases present in early infancy with life-threatening metabolic decompensation, and these episodes of hyperammonemia can be fatal or result in permanent neurologic damage. Despite the progress in pharmacologic treatment, long-term survival is poor especially for severe cases. Liver transplant is an alternative treatment option, providing sufficient enzymatic activity and decreasing the risk of metabolic decompensation. Three patients with urea cycle defects received related living-donor liver transplants at our hospital. Patients presented with late-onset ornithine transcarbamylase deficiency, argininosuccinate lyase deficiency, and citrullinemia. Maximum pretransplant ammonia levels were between 232 and 400 μmol/L (normal range is 18-72 μmol/L), and maximum posttransplant values were 52 to 94 μmol/L. All patients stopped medical treatment and dietary protein restriction for urea cycle defects after transplant. The patient with late-onset ornithine transcarbamylase deficiency already had motor deficits related to recurrent hyperammonemia attacks pretransplant. A major improvement could not be achieved, and he is wheelchair dependent at the age of 6 years. The other 2 patients had normal motor and mental skills before transplant, which have continued 12 and 14 months after transplant. Hepatic artery thrombosis in the patient with the ornithine transcarbamylase deficiency, intraabdominal infection in the patient with argininosuccinate lyase deficiency, and posterior reversible encephalopathy syndrome in the patient with citrullinemia were early postoperative complications. Histopathologic changes in livers explanted from patients with ornithine transcarbamylase deficiency and citrullinemia were nonspecific. The argininosuccinate lyase-deficient patient had portoportal fibrosis and cirrhotic

    As part of an extensive research project on securing continuity of care through Pflegeüberleitung, data on experiences of patients and their relatives regarding discharge from hospital were collected and analysed by means of a qualitative study. Ten focused interviews were conducted and analysed with five patients and five relatives, respectively. From the results of the patient interviews, the subjective experience of being ill was identified as a main issue, constituting a dimension which pervades all other categories of the results. Patients judge nursing measures regarding the discharge planning in the light of this dimension. The results of the interviews with relatives indicate the lack of interdisciplinary cooperation and coordination. Relatives complain about the missing attempts to come to agreements and about their perspective not being considered regarding care needs as well as the date of discharge. There is a need for the development of new approaches to care and treatment in the hospital which allow for the patient's and the relatives' participation and co-shaping, thereby recognizing an altered understanding of the respective roles. In order to achieve systematic integration of the clients' perspectives, thus securing individual continuity of care, programmes for professional consultancy play an important part of these new approaches.

    Recently several reports have extended the apolipoprotein E (APOE) {epsilon}4 association found in late-onset Alzheimer`s disease (LOAD) patients to early-onset (EO) AD patients. We have studied this question in a large population of 119 EOAD patients (onset {<=}60 years) in which family history was carefully assessed and in 109 controls. We show that the APOE {epsilon}A allele frequency is increased only in the subset of patients who belong to families where LOAD secondary cases are present. Our sampling scheme permits us to demonstrate that, for an individual, bearing at least one {epsilon}4 allele increases both the risk of AD before age 60 and the probability of belonging to a family with late-onset affected subjects. Our results suggest that a subset of EOAD cases shares a common determinism with LOAD cases. 19 refs., 3 tabs.

    Opinions of patients and relatives about their experiences with health and social services were assessed in a pilot study. The study was carried out in collaboration with two patients' Associations of Neurofibromatosis, "Neurofibromatosi--Onlus" and "LINFA--Onlus". An ad-hoc questionnaire was developed by the Italian National Centre of Rare Diseases and was sent to the Responsibles of the two aforementioned patients' Associations. The Responsibles distributed the questionnaire to their members by mail. The questionnaire investigated, using 5-level Likert scales, the following topics: quality and accessibility of health services (diagnostic exams, pharmacological therapies, rehabilitation, psychological support), quality and accessibility of social services (school, vocational training, health information, information on legal matters and rights). Finally, the questionnaire investigated also opinions about improvements of public health and social services in the last three years. Overall, 79 out 144 questionnaires were filled by patients or their relatives. The most frequent negative experiences concerned vocational training and both health and legal information. The most frequent positive opinions were reported for the human relationships with health professionals. This pilot study seems to point out a promising way to investigate systematically opinions of patients suffering from rare diseases and their relatives.

    OBJECTIVE To examine variables associated with perceived diabetes control compared with an objective measure of glucose control (A1C). RESEARCH DESIGN AND METHODS Beliefs about diabetes were assessed among 334 individuals with diabetes living in a primarily low-income, minority, urban neighborhood. Regression analyses tested associations between disease beliefs and both participants' perceptions of control and actual control (A1C). RESULTS Poorer perceived diabetes control was associated with perceiving a greater impact of diabetes, greater depressive symptoms, not following a diabetic diet, A1C, and a trend toward less exercise. Variables associated with better actual control (A1C) included higher BMI, older age, and not using insulin. CONCLUSIONS Patients' perceptions of their diabetes control are informed by subjective diabetes cues (e.g., perceived impact of diabetes and adherence to a diabetic diet), which are not related to A1C. Clinicians should take into account what cues patients are using to assess their diabetes control. PMID:20067972

    Schizophrenia (SZ) and bipolar disorder (BD) share clinical features, genetic risk factors and neuroimaging abnormalities. There is evidence of disrupted connectivity in resting state networks in patients with SZ and BD and their unaffected relatives. Resting state networks are known to undergo reorganization during youth coinciding with the period of increased incidence for both disorders. We therefore focused on characterizing resting state network connectivity in youth at familial risk for SZ or BD to identify alterations arising during this period. We measured resting-state functional connectivity in a sample of 106 youth, aged 7-19 years, comprising offspring of patients with SZ (N = 27), offspring of patients with BD (N = 39) and offspring of community control parents (N = 40). We used Independent Component Analysis to assess functional connectivity within the default mode, executive control, salience and basal ganglia networks and define their relationship to grey matter volume, clinical and cognitive measures. There was no difference in connectivity within any of the networks examined between offspring of patients with BD and offspring of community controls. In contrast, offspring of patients with SZ showed reduced connectivity within the left basal ganglia network compared to control offspring, and they showed a positive correlation between connectivity in this network and grey matter volume in the left caudate. Our findings suggest that dysconnectivity in the basal ganglia network is a robust correlate of familial risk for SZ and can be detected during childhood and adolescence. PMID:26885824

    Total hip arthroplasty reduces pain and restores physical function in patients with hip joint problems. This study examined lifestyle and health-related quality of life before and after total hip arthroplasty in Japanese and Chinese patients. Two hospitals in China recruited 120 patients and 120 Japanese patients matched by age and operative status were drawn from a prospective cohort database. Oxford Hip Score, EuroQol, and characteristics of Asian lifestyle and attitudes toward the operation were assessed. There were no differences between patients from the two countries in quality-of-life-scale scores: postoperative patients had significantly better quality-of-life scores than preoperative patients in both countries. In China, patients who reported that living at home was inconvenient had significantly worse Oxford Hip Scores than those who did not. Mean scores for anxiety items concerning possible dislocation and durability of the implant were significantly higher in Japanese than in Chinese subjects. Our findings suggest that providing information about housing conditions and lifestyles would result in improved quality of life and reduced anxiety in patients with implanted joints.

Methods: A prospective, observational study was conducted among 133 patients with stroke disease who were aged 18 years or older and admitted to the general medicine ward. During the 6 months study period, the incidence of DRPs was identified using the Pharmaceutical Care Network Europe Foundation classification system, version 6.2. Findings: A total of 133 patients were screened for DRPs. Among them, 120 patients have at least one DRP. A total of 254 DRPs were identified (on average, 2.015 DRPs per each patient case). Conclusion: Increasing the evidence of the incidence of medication-related problems in tertiary care hospitals indicates the need for the establishment of a clinical pharmacist in hospital settings.

Objective: The aim of the study was to describe the first case of Cushing syndrome associated with MTC in a pediatric patient and the successful reversal of Cushing syndrome with tyrosine kinase inhibitor (vandetanib) therapy. Patient and Methods: A 17-year-old Brazilian adolescent presented with metastatic MTC and associated ACTH-dependent ectopic Cushing syndrome in the context of multiple endocrine neoplasia type 2B. When the patient was treated with the tyrosine kinase inhibitor vandetanib, rapid decrease in serum cortisol and improvement of clinical symptoms were observed. Conclusion: We describe the first pediatric case of clinical and biochemical improvement of paraneoplastic MTC-related Cushing syndrome after treatment with vandetanib. Vandetanib and possibly other tyrosine kinase inhibitors may be a novel beneficial option in patients with neuroendocrine tumor-related ectopic Cushing syndrome. PMID:24617713

    Transfusion-related acute lung injury (TRALI) is a serious adverse reaction of transfusion, and presents as hypoxemia and non-cardiogenic pulmonary edema within 6 hours of transfusion. A 14-year-old primigravida woman at 34 weeks of gestation presented with upper abdominal pain without dyspnea. Because she showed the syndrome of HELLP (hemolysis, elevated liver enzymes, and low platelet count), an emergency cesarean section delivery was performed, and blood was transfused. In the case of such patients, clinicians should closely observe the patient's condition at least during the 6 hours while the patient receives blood transfusion, and should suspect TRALI if the patient complains of respiratory symptoms such as dyspnea. Furthermore, echocardiography should be performed to distinguish between the different types of transfusion-related adverse reactions.

    The Ben-Tovim Walker Body Attitudes Questionnaire (BAQ) is a psychometrically sound self-report instrument for assessing women's attitudes towards their own bodies. The BAQ responses of a large sample of patients with eating disorders (ED) diagnosed in accordance with DSM-III-R criteria were compared with those from a normative population and from diverse groups of psychiatrically and physically ill patients. The ED group was distinct, and showed extreme responses in the area of weight and shape concerns. But a better discrimination between the ED and other populations was achieved using subscales that related to 'body disparagement' (an intense loathing of the body) and 'attractiveness', rather than to weight and shape concerns. ED patients may have a more pervasive disturbance in body-related attitudes than is currently widely accepted. Patients with anorexia and bulimia nervosa showed very similar attitudes despite the symptomatic differences between the groups. PMID:1488491

    Purpose As several years have passed since the implementation of the Korean diagnosis-related group (DRG) payment system for appendicitis, its early outcomes should be assessed to determine if further improvements are warranted. Methods We retrospectively analyzed clinical data from Korean patients who underwent appendectomy, dividing the sample into 2 groups of those who received services before and after implementation of the DRG system. Based on the DRG code classification, patient data were collected including the amount of DRG reimbursement and the total in-patient costs. We subsequently performed univariate and multivariate analyses to identify independent factors contributing to higher total in-patient cost. Results Although implementation of the DRG system for appendicitis significantly reduced postoperative length of stay (2.8 ± 1.0 days vs. 3.4 ± 1.9 days, P < 0.001), it did not reduce total in-hospital cost. The independent factors related to total inhospital cost included patient age of 70 years or more (odds ratio [OR], 3.214; 95% confidence interval [CI], 1.769–5.840; P < 0.001) and operation time longer than 100 minutes (OR, 3.690; 95% CI, 2.007–6.599, P < 0.001). In addition, older patients (≥70 years) showed a nearly 10 times greater relative risk for having a comorbid condition (95% CI, 5.141–20.214; P < 0.001) and a 3.255 times greater relative risk for having higher total in-hospital cost (95% CI, 1.731–6.119, P < 0.001). Conclusion It appears that older patients (>70 years) have greater comorbidities, which contribute to higher inpatient costs. Thus, our study suggests that patient age be considered as a DRG classification variable. PMID:27478811

    AIM To find the significant altered proteins in age-related macular degeneration (AMD) patients as potential biomarkers of AMD. METHODS A comparative analysis of the protein pattern of AMD patients versus healthy controls was performed by means of proteomic analysis using two-dimensional gel electrophoresis followed by protein identification with MALDI TOF/TOF mass spectrometry. RESULTS We identified 28 proteins that were significantly altered with clinical relevance in AMD patients. These proteins were involved in a wide range of biological functions including immune responses, growth cytokines, cell fate determination, wound healing, metabolism, and anti-oxidance. CONCLUSION These results demonstrate the capacity of proteomic analysis of AMD patient plasma. In addition to the utility of this approach for biomarker discovery, identification of alterations in endogenous proteins in the plasma of AMD patient could improve our understanding of the disease pathogenesis.

    Patient satisfaction has become an important indicator of process quality inside hospitals. Even so, the improvement of patient satisfaction cannot simply follow from the implementation of new incentives schemes and organisational arrangements; it also depends on hospitals' cultures and climates. This paper studies the impact of alternative models of organisational climate in hospital wards on patient satisfaction. Data gathered from seven public hospitals in Italy are used to explore this relationship. The theoretical approach adopted is the Competing Value Framework which classifies organisations according to their inward or outward focus and according to the importance assigned to control vs. flexibility. Results show that both a model stressing openness, change and innovation and a model emphasising cohesion and workers' morale are positively related to patient satisfaction, while a model based on managerial control is negatively associated with patient satisfaction.

    This study included a sample of 57 Anglo-American, Latino American, and African American patients with schizophrenia and their family members. Findings indicate that for patients, as hypothesized, increasing perceptions of family cohesion was associated with less general emotional distress and fewer psychiatric symptoms. For family members of Latino and African American descent, greater self-reported family cohesion also appeared to have a protective effect against emotional distress, as hypothesized. However, no association was found between family cohesion and general emotional distress for Anglo-American family members. Interestingly, no relationship was found between patients' and their relatives' views of their family environment. Thus, researchers and clinicians working with families are encouraged to attain separate assessments of the family environment from each individual member.

    Patient satisfaction has become an important indicator of process quality inside hospitals. Even so, the improvement of patient satisfaction cannot simply follow from the implementation of new incentives schemes and organisational arrangements; it also depends on hospitals' cultures and climates. This paper studies the impact of alternative models of organisational climate in hospital wards on patient satisfaction. Data gathered from seven public hospitals in Italy are used to explore this relationship. The theoretical approach adopted is the Competing Value Framework which classifies organisations according to their inward or outward focus and according to the importance assigned to control vs. flexibility. Results show that both a model stressing openness, change and innovation and a model emphasising cohesion and workers' morale are positively related to patient satisfaction, while a model based on managerial control is negatively associated with patient satisfaction.

    Although the pathogenesis of age-related macular degeneration (AMD) is unclear, genetic screening has revealed that polymorphisms in the complement system may be associated with AMD development. Production of autoantibodies was also found in AMD patients. In this study, we analyzed the antibody response in AMD patients. We found that purified B cells from AMD patients tended to respond to lower concentrations of bacterial antigen stimulation, and produced higher amounts of antibodies, especially in IgM and IgA secretions. When examining clinical symptoms, patients with more severe wet-form AMD tended to exhibit higher sensitivity to bacterial antigens and secreted more IgM and IgA antibodies than those with less severe dry-form cases. In conclusion, our study discovered an altered B-cell antibody production in response to bacterial antigens in AMD patients, which potentially contributes to AMD pathogenesis.

    Introduction: When cancer patients have advanced disease and a primary cure is no longer possible, the focus is on maintaining the patientʼs quality of life. Recent therapeutic advances in breast cancer treatment mean that even patients with metastatic disease can remain stable for long periods of time. The aim of this study was to look at the health-related quality of life (HRQL) of these patients and compare it with data for the general population and to show the differences in outcomes for different survey instruments used to measure quality of life. Material and Methods: A total of 96 breast cancer patients with metastatic disesae or receiving adjuvant therapy were questioned about their quality of life. Patients were investigated using the established survey instruments EORTC QLQ-C30, EORTC QLQ-BR23, EQ-5D-5L and EQ VAS. All patients filled out questionnaires. Statistical analysis was done using MS Excel and SPSS. Results: Although the questionnaires were completed at the same time, the different questionnaires showed significant differences with regard to the level of stress experienced by the patient. When the EQ VAS questionnaire was used, the patientʼs current state of health was assessed as significantly better than with the EORTC QLQ-C30. Overall, all aspects of patientsʼ quality of life were found to be in need of optimization and HRQL of patients was significantly poorer in all areas compared to the reference population. Conclusion: To improve the quality of life of patients with metastatic disease, it is necessary to continuously monitor the success of therapy. The choice of survey tools is highly relevant as assessments differ considerably depending on the choice of questionnaire. PMID:27761027

    One of the biggest problems of work life today is burnout. With burnout, satisfaction of clients and service givers reduces. In this study, burnout levels of nurses working in the internal, surgical and intensive care units of a university hospital and the unmet needs of the patients' relatives related to nursing care were investigated. In the study, 225 nurses and 222 relatives of patients constituted the sample group of this study. Three separate forms were used in the study, namely, Nurse and Patient Relative Identification Form, the Maslach Burnout Inventory and the Nursing Services Satisfaction Inventory. In the study, burnout levels of the nurses were found to be high. Conditions like younger ages, scarcity of experience in the profession, lower levels of education, having chosen the profession and the unit they work in not willingly and working in environments like intensive care increase the burnout and as a result, expectations of the relatives of patients from nursing care are not fully met. Some suggestions have been made to make some regulations to prevent the burnout of nurses and to increase the satisfaction of relatives.

    OBJECTIVES: Colorectal cancer is the third leading cause of cancer death in the United States. The American College of Gastroenterology recommends screening for first-degree relatives of patients diagnosed with colorectal cancer before the age of 50. A colonoscopy is one of the most commonly recommended exams due to its specificity and the possibility to resect pre-malignant lesions. Nevertheless, the rate of physician adherence to this recommendation is unknown. METHODS: This transversal study was performed at a major cancer center in Brazil with 62 patients, aged 18 to 50, who completed a questionnaire on information received from their physicians regarding screening their first-degree relatives. We used the answers from patients who provided explicit consent. RESULTS: Two hundred and three patients were eligible to participate and 93 (45.8%) agreed to complete the questionnaire. Twenty-three questionnaires (24.73%) were returned and 39 were completed by telephone. Of the patients who answered the questionnaire, 39 (62.9%) had received a colonoscopy recommendation for their first-degree relatives and 23 (37.1%) were not informed of the recommendation. Among the patients who received the recommendations, 20.51% affirmed that all relatives completed the exam and 51.28% stated that no relatives completed the exam. DISCUSSION: The adherence rate of our physicians to the ACG guideline recommendations was 62.9%. Considering that our study was performed at a leading center for cancer treatment in Latin America, we had expected better adherence. The results show that adherence to the colorectal cancer screening recommendations for high-risk patients must be improved. PMID:26598083

    Background: Catheter-related infections (CRIs) are a significant source of morbidity and mortality in hemodialysis patients. The identification of novel, modifiable risk factors for CRIs may lead to improved outcomes in this population. Peripherally inserted central catheters (PICCs) have been hypothesized to compromise vascular access due to vascular damage and venous thrombosis, whereas venous thrombosis has been linked to the development of CRIs. Here we examine the association between PICC placement and CRIs. Methods: A retrospective review was performed of all chronic hemodialysis catheter placements and exchanges performed at a large university hospital from September 2003 to September 2008. History of PICC line use was determined by examining hospital radiologic records from December 1993 to September 2008. Catheter-related complications were assessed and correlated with PICC line history. Results: One hundred eighty-five patients with 713 chronic tunneled hemodialysis catheter placements were identified. Thirty-eight of those patients (20.5%) had a history of PICC placement; these patients were more likely to have CRIs (odds ratio = 2.46, 95% confidence interval = 1.71-3.53, p < .001) compared with patients without a history of PICC placement. There was no difference between the two groups in age or number of catheters placed. Conclusion: Previous PICC placement may be associated with catheter-related infections in hemodialysis patients.

    Purpose: To evaluate the relationship between vision-related quality of life (QOL) as measured by the short-form 11-item Japanese version of the Visual Function Questionnaire (VFQ-J11) and the severity of visual field (VF) defects in patients with glaucoma. Methods: The study included 134 glaucoma patients and 30 normal subjects. VF testing using the Humphrey Field Analyzer was performed to obtain both the VF index (VFI) and MD in both eyes of each glaucoma patient. Binocular integrated VF was constructed for each patient by merging corresponding sensitivity values from monocular VFs, and the correlation between visual function and vision-related QOL was then assessed. Results: A significant relationship was found between QOL and VF in 6 of 7 subscales on the VFQ-J11, and between the composite scores in both the better eye and the worse eye in glaucoma patients. The relationship was stronger in the worse eye than in the better eye. Overall, correlation coefficients of the VFI were higher than those of MD and slightly higher than those of integrated VF in the worse eye. Conclusions: The VFI showed a marginally better correlation than MD. Assessment of VFI in the worse eye may provide useful information regarding vision-related QOL in glaucoma patients.

    Temporal lobe abnormalities and emotion recognition deficits are prominent features of schizophrenia and appear related to the diathesis of the disorder. This study investigated whether temporal lobe structural abnormalities were associated with facial emotion recognition deficits in schizophrenia and related to genetic liability for the disorder. Twenty-seven schizophrenia patients, 23 biological family members, and 36 controls participated. Several temporal lobe regions (fusiform, superior temporal, middle temporal, amygdala, and hippocampus) previously associated with face recognition in normative samples and found to be abnormal in schizophrenia were evaluated using volumetric analyses. Participants completed a facial emotion recognition task and an age recognition control task under time-limited and self-paced conditions. Temporal lobe volumes were tested for associations with task performance. Group status explained 23% of the variance in temporal lobe volume. Left fusiform gray matter volume was decreased by 11% in patients and 7% in relatives compared with controls. Schizophrenia patients additionally exhibited smaller hippocampal and middle temporal volumes. Patients were unable to improve facial emotion recognition performance with unlimited time to make a judgment but were able to improve age recognition performance. Patients additionally showed a relationship between reduced temporal lobe gray matter and poor facial emotion recognition. For the middle temporal lobe region, the relationship between greater volume and better task performance was specific to facial emotion recognition and not age recognition. Because schizophrenia patients exhibited a specific deficit in emotion recognition not attributable to a generalized impairment in face perception, impaired emotion recognition may serve as a target for interventions.

    Thirty-two patients with AIDS related complex (ARC) or acquired immunodeficiency syndrome (AIDS) underwent /sup 67/Ga scans as part of their evaluation. Three patterns of /sup 67/Ga biodistribution were found: lymph node uptake alone; diffuse pulmonary uptake; normal scan. Gallium-67 scans were useful in identifying clinically occult Pneumocystis carinii pneumonia in seven of 15 patients with ARC who were asymptomatic and had normal chest radiographs. Gallium scans are a useful ancillary procedure in the evaluation of patients with ARC or AIDS.

    Surgical site infections (SSI) following total hip arthroplasty (THA) have a significantly adverse impact on patient outcomes and pose a great challenge to the treating surgeon. Therefore, timely recognition of those patients at risk for this complication is very important, as it allows for adopting measures to reduce this risk. This review discusses literature reported risk factors for SSI after THA. These can be classified into patient-related factors (age, gender, obesity, comorbidities, history of infection, primary diagnosis, and socioeconomic profile), surgery-related factors (allogeneic blood transfusion, DVT prophylaxis and coagulopathy, duration of surgery, antibiotic prophylaxis, bearing surface and fixation, bilateral procedures, NNIS index score, and anesthesia type), and hospital-related factors (duration of hospitalization, institution and surgeon volume, and admission from a healthcare facility). All these factors are discussed with respect to potential measures that can be taken to reduce their effect and consequently the overall risk for infection. PMID:26075298

    Background: Between 2005 and 2010, we treated patients with hydrocephalus related to cerebral metastases, who were not good candidates for surgical resection by either endoscopic third ventriculostomy (ETV) or ventriculoperitoneal shunting (VPS). Patients were excluded from ETV if they had a clinical history suggestive of non-obstructive hydrocephalus, including: (1) history of infection or ventricular hemorrhage and (2) leptomeningeal carcinomatosis. The rest of the patients were treated with VPS. Methods: We analyzed the clinical outcome of these patient cohorts, to determine whether the efficacy of VPS was compromised due to a history of infection, ventricular hemorrhage, or leptomeningeal carcinomatosis, and compared these results to those patients who underwent ETV. Results: Sixteen patients were treated with ETV and 36 patients were treated with VPS. The overall efficacy of symptomatic palliation was comparable in the ETV and VPS patients (ETV = 69%, VPS = 75%). In both groups, patients with more severe hydrocephalic symptoms such as nausea, vomiting, and lethargy were more likely to benefit from the procedure. The overall complication rate for the two groups was comparable (ETV = 12.6%, VPS = 19.4%), although the spectrum of complications differed. The overall survival, initial Karnofsky performance status (KPS), and three-month KPS, were similarly comparable (median survival: ETV 3 months, VPS 5.5 months; initial KPS: ETV = 66 ± 7, VPS = 69 ± 12; 3 months KPS: ETV = 86 ± 7, KPS = 84 ± 12). Conclusion: VPS remains a reasonable option for poor RPA grade metastasis patients with hydrocephalus, even in the setting of a previous infection, hemorrhage, or in those with leptomeningeal disease. Optimal treatment of this population will involve the judicious consideration of the relative merits of VPS and ETV. PMID:23061013

    The purpose of this study is to evaluate the intraocular inflammation at a sub clinical level, in patients suffering from Sjogren's syndrome (SS-I) and Rheumatoid Arthritis (RA), to relate it with the ocular surface status and to verify the diagnostic performance of the method. Twenty-eight patients suffering from SS-I, 31 patients suffering from RA and 31 normal subjects matched in age and gender were included in the study. A Kowa 500F laser cell flare meter was utilized to quantify the aqueous cells and flare in vivo, ocular surface inflammation was graded by conjunctival cytology and dosage of serum albumin in tears, eye dryness was scored with Tear Function Index. All data resulted significantly different in both SS-I and RA patients vs. control group and also different comparing SS-I vs. RA patients group, except for the Flare values. A blood-aqueous barrier breakdown occurs either in SS-I and RA patients; the degree of the damage is related with ocular surface inflammation and dryness. We recommend the aqueous flare be analysed in those rheumatic patients where an ocular surface inflammation has been documented.

    Cancer related fatigue (CRF) is a common and debilitating symptom that can influence quality of life (QoL) in cancer patients. The increase in survival times stresses for a better understanding of how CRF affects patients' QoL. This was a cross-sectional descriptive study with 148 randomly recruited prostate cancer patients aiming to explore CRF and its impact on QoL. Assessments included the Cancer Fatigue Scale, EORTC QLQ-C30, and EORTC QLQ-PR25. Additionally, 15 in-depth structured interviews were performed. Quantitative data were analyzed with simple and multiple regression analysis and independent samples t-test. Qualitative data were analyzed with the use of thematic content analysis. The 66.9% of the patients experienced CRF with higher levels being recorded for the affective subscale. Statistically significant differences were found between the patients reporting CRF and lower levels of QoL (mean = 49.1) and those that did not report fatigue and had higher levels of QoL (mean = 72.1). The interviews emphasized CRF's profound impact on the patients' lives that was reflected on the following themes: “dependency on others,” “loss of power over decision making,” and “daily living disruption.” Cancer related fatigue is a significant problem for patients with advanced prostate cancer and one that affects their QoL in various ways.

    Objectives: We aimed to investigate potential associations between human leukocyte antigen (HLA) class I and class II alleles and the development of anaphylactic/anaphylactoid reactions in patients with multiple sclerosis (MS) treated with natalizumab. Methods: HLA class I and II genotyping was performed in patients with MS who experienced anaphylactic/anaphylactoid reactions and in patients who did not develop infusion-related allergic reactions following natalizumab administration. Results: A total of 119 patients with MS from 3 different cohorts were included in the study: 54 with natalizumab-related anaphylactic/anaphylactoid reactions and 65 without allergic reactions. HLA-DRB1*13 and HLA-DRB1*14 alleles were significantly increased in patients who developed anaphylactic/anaphylactoid reactions (pM-H = 3 × 10−7; odds ratio [OR]M-H = 8.96, 95% confidence interval [CI] = 3.40–23.64), with a positive predictive value (PPV) of 82%. In contrast, the HLA-DRB1*15 allele was significantly more represented in patients who did not develop anaphylactic/anaphylactoid reactions to natalizumab (pM-H = 6 × 10−4; ORM-H = 0.2, 95% CI = 0.08–0.50), with a PPV of 81%. Conclusions: HLA-DRB1 genotyping before natalizumab treatment may help neurologists to identify patients with MS at risk for developing serious systemic hypersensitivity reactions associated with natalizumab administration.

    Aging in the immune system results in tendency to proinflammatory responses. Intradermal DNA immunization showed Th2 polarized noninflammatory immune responses. We tested here 18-month-old mice which were immunized with Aβ42 peptide, DNA Aβ42 trimer, or 2 different prime boost protocols identical to previous experiments. High Aβ42 antibody levels were found in aged mice which had received peptide immunizations (900 μg/mL plasma), and in mice which had received peptide prime and DNA boost immunizations (500 μg/mL), compared with antibodies in DNA Aβ42 immunized mice with 50 μg/mL. Although we found T-cell proliferation and inflammatory cytokines in mice which had received peptide or prime boost immunization, these were not found in DNA-immunized mice. The results are concordant with proinflammatory responses because of immunosenescence and contraindicate the use of Aβ42 peptide immunizations or prime boost immunization protocols for the use in elderly Alzheimer's disease patients. DNA Aβ42 immunization only on the other hand does lead to effective levels of antibodies without inflammatory cytokine or T-cell responses in the aged animal model tested. PMID:25725942

    The treatment of psychiatric patients requires different health care from that of patients from other medical specialties. In particular, in the case of Department of Psychiatry from the Zamora Hospital (Spain), the period of time which patients require institutionalized care is a tiny part of their treatment. A large part of health care provided to the patient is aimed at his/her rehabilitation and social integration through day-care centres, supervised flats or activities. Conversely, several reports reveal that approximately 50 % of Internet users use the network as a source of health information, which has led to the emergence of virtual communities where patients, relatives or health professionals share their knowledge concerning an illness, health problem or specific health condition. In this context, we have identified that the relatives have a lack of information regarding the daily activities of patients under psychiatric treatment. The social networks or the virtual communities regarding health problems do not provide a private space where relatives can follow the patient's progress, despite being in different places. The goal of the study was to use technologies to develop a private social network for being used by severe mental patients (mainly schizophrenic patients). SocialNet is a pioneer social network in the health sector because it provides a social interaction context restricted to persons authorized by the patient or his/her legal guardian in such a way that they can track his/her daily activity. Each patient has a private area only accessible to authorized persons and their caregivers, where they can share pictures, videos or texts regarding his/her progress. A preliminary study of usability of the system has been made for increasing the usefulness and usability of SocialNet. SocialNet is the first system for promoting personal interactions among formal caregivers, family, close friends and patient, promoting the recovery of schizophrenic

    2013-01-01

    Background Although pain is frequently experienced by patients with cancer, it remains under-treated. The primary aim of this study was to estimate the prevalence of cancer-related neuropathic pain (CRNP) in patients with chronic pain who attended an outpatient clinic for standard care in Europe (irrespective of the reason or stage of the cancer). The secondary aims of this study were to characterise pain and cancer in patients with CRNP (including treatment) and to evaluate the usefulness of the painDETECT (PD-Q) screening tool to help physicians identify a potential neuropathic component of cancer-related pain. Methods An observational, non-interventional, cross-sectional, multi-centre study of adult patients with cancer using patient and physician case report forms (CRFs). Patients with CRNP were identified by physicians’ clinical assessments after examining the completed PD-Q. Results A total of 951 patients visiting outpatient clinics across Europe were enrolled in this study between August 2010 and July 2011. Of these, 310 patients (32.60%; 95% confidence interval 29.62, 35.58) were identified as having CRNP. Twenty-nine of 39 (74.4%) physicians who completed the CRF relating to the PD-Q considered it a useful tool to help detect CRNP in daily practice and 28 of 39 (71.8%) indicated that they would use this tool in the future for most or some of their patients. Data from physicians before and after review of the completed PD-Qs showed a shift in clinical opinion (either to positive CRNP diagnosis [yes] or negative CRNP diagnosis [no]) in respect of 142 patients; about half of which (74) were categorised with an initial diagnosis of unknown. Opinions also shifted from a no to a yes diagnosis in 10 patients and from a yes to a no diagnosis in 51 patients. Conclusions Approximately one-third of adults with cancer experiencing chronic pain attending outpatient clinics as part of routine care were considered to have CRNP in the opinion of the physicians after

    Previous studies have suggested that social cognition is affected in individuals with schizophrenia. The purpose of this study was to explore to what extent social cognition deficits are shared by unaffected first-degree relatives, and the nature of the relationship between performance in different paradigms of social cognition. 20 Schizophrenia patients (7 females, 31+/-10 years), 20 healthy age- and gender-matched individuals, 20 unaffected first-degree relatives of the schizophrenia patients (11 females, 50+/-20 years), and 20 healthy individuals matched for age and gender were recruited. Patients showed deficits in the detection of social Faux Pas (0.80+/-0.17 vs. controls: 0.94+/-0.09, p=0.025) and the correct identification of Theory of Mind stories (0.71+/-0.13 vs. controls: 0.82+/-0.12, p=0.038). Relatives performed poorly in the Faces Test (0.83+/-0.14 vs. controls: 0.9+/-0.08, p=0.048), the Reading the Mind in the Eyes Test (0.59+/-0.17 vs. controls: 0.71+/-0.14, p=0.046) and the detection of social Faux Pas (0.8+/-0.2 vs. controls: 0.93+/-0.09, p=0.024). Abnormalities were independent of age, years of education, and general cognitive performance in patients and their relatives. Performance in an Emotion Processing task (Faces Test) was correlated with performance in theory of mind tests in healthy individuals and relatives of patients with schizophrenia only. These results suggest that schizophrenia patients and their unaffected first-degree relatives display similar but nonidentical patterns of social cognition processing.

    Background Immune system activation is frequently reported in patients with Alzheimer's disease (AD). However, it remains unknown whether this is a cause, a consequence, or an epiphenomenon of brain degeneration. Objective The present study examines whether immunological abnormalities occur in a well-established murine AD model and if so, how they relate temporally to behavioral deficits and neuropathology. Methods A broad battery of tests was employed to assess behavioral performance and autoimmune/inflammatory markers in 3xTg-AD (AD) mice and wild type controls from 1.5 to 12 months of age. Results Aged AD mice displayed severe manifestations of systemic autoimmune/inflammatory disease, as evidenced by splenomegaly, hepatomegaly, elevated serum levels of anti-nuclear/anti-dsDNA antibodies, low hematocrit, and increased number of double-negative T splenocytes. However, anxiety-related behavior and altered spleen function were evident as early as 2 months of age, thus preceding typical AD-like brain pathology. Moreover, AD mice showed altered olfaction and impaired “cognitive” flexibility in the first 6 months of life, suggesting mild cognitive impairment-like manifestations before general learning/memory impairments emerged at an older age. Interestingly, all of these features were present in 3xTg-AD mice prior to significant amyloid-β or tau pathology. Conclusion The results indicate that behavioral deficits in AD mice develop in parallel with systemic autoimmune/inflammatory disease. These changes antedate AD-like neuropathology, thus supporting a causal link between autoimmunity and aberrant behavior. Consequently, 3xTg-AD mice may be a useful model in elucidating the role of immune system in the etiology of AD. PMID:24150111

    Erlotinib is a tyrosine kinase inhibitor of the epidermal growth factor receptor. Since there is a wide expression of the epidermal growth factor receptors in the epithelial tissues of ocular surface and adnexa, ocular adverse reactions may happen during systemic administration of erlotinib. Previously reported ocular adverse reactions of erlotinib include trichomegaly, periorbital rash, ectropion, blepharitis, persistent corneal epithelial defect, corneal ulcer and perforation. We report the first case of erlotinib-related keratopathy in a patient who had received laser in situ keratomileusis. The patient presented a special picture of flap striae related to erlotinib.

    Objectives To quantify health related quality of life (HRQOL) of patients with biliary atresia with their native livers and compare them with healthy children and patients with biliary atresia post-liver transplant (LT) and to examine the relationship between HRQOL and medical variables. Study design A cross-sectional HRQOL study of patients with biliary atresia with their native livers (ages 2-25 years) was conducted and compared with healthy and post-LT biliary atresia samples using PedsQL™ 4.0 child self and parent proxy reports, a validated measure of physical/psychosocial functioning. Results 221 patients with biliary atresia with native livers (54% female, 67% white) were studied. patient self and parent proxy reports showed significantly poorer HRQOL than healthy children across all domains (p < 0.001), particularly in emotional and psychosocial functioning. Child self and parent proxy HRQOL scores from patients with biliary atresia with their native livers and post-LT biliary atresia were similar across all domains (p=NS). Child self and parent proxy reports showed moderate agreement across all scales, except social functioning (poor to fair agreement). On multivariate regression analysis, black race and elevated total bilirubin were associated with lower Total and Psychosocial HRQOL summary scores. Conclusions HRQOL in patients with biliary atresia with their native livers is significantly poorer than healthy and similar to post-LT biliary atresia children. These findings identify significant opportunities to optimize the overall health of patients with biliary atresia. PMID:23746866

    PurposeTo determine the opinions from a patient perspective on relevant variables in the delivery of treatment for neovascular age-related macular degeneration (nAMD).MethodsPilot interviews with patients and doctors were conducted to identify what variables in the provision of a nAMD service were important. This led to the generation of two sets of scenario options. Subsequently 100 patients undergoing active treatment for nAMD in the National Health Service University Hospital, United Kingdom underwent interview assessment. They were asked to rank their preferences for provision of their care with reference to these two sets of scenario options. Using conjoint analysis, percentage preferences, and utility scores for each variable in each scenario design were calculated.ResultsNinety-five patients completed the preference ranking for both scenarios. Eight patients ranked worse vision as preferable to better vision and were excluded on the basis that they had not understood the task. The results of the remaining 87 patients are presented. The most important factor to patients was having good vision, followed by a one-stop service and less frequent follow up. The least important factors were label status of the drug, cost to the health service, and grade of the injector.ConclusionPatients regard good vision and minimal visits to the hospital above the status of injector, label status of drug, or cost to the NHS.

    Type 2 diabetes mellitus (T2DM) patients have an increased risk of cardiovascular disease (CVD) that represents one of the main causes of mortality in this population. The knowledge of the underlie factors involved in the development of CVD and the discovery of new biomarkers of the disease could help to early identification of high-risk patients. Using liquid chromatography coupled to high resolution mass spectrometry (LC-HRMS) we analyzed the serum metabolomic profile of 30 subject distributed according three groups: (i) T2DM patients with CVD; (ii) T2DM patients without CVD; (iii) non-diabetic subjects as controls (C) in order to identify potential biomarkers of the CVD related to T2DM. A partial least squares discriminant analysis (PLS-DA) and one-way analysis of variance (ANOVA) were applied to identify differential metabolites between different groups. Four glycerophospholipids were further identified as potential biomarkers of CVD in T2DM patients. Specifically, a reduction in phosphatidylcholine, lysophosphatidylcholine and lysophosphatidylethanolamine (LPE) serum levels were found in T2DM patients compared to controls, presenting the patients with CVD the lowest serum levels of these metabolites. These results show a generalized reduction of circulating phospholipids species in T2DM patients which is more pronounced in those with CVD providing information of the pathways involved in the pathogenesis and progression of CVD associated to T2DM.

    The objective of this study was to assess current treatment patterns, blood glucose test strip usage, and treatment compliance in patients with type 2 diabetes mellitus (T2DM) in primary care centers in Spain, and to assess factors related to glycemic control. We conducted a retrospective chart review of patients with T2DM and measured treatment compliance using the Morisky-Green questionnaire. 294 patients were included in the study from a population of patients attending 30 primary care centers throughout Spain. Results showed that the majority of patients were treated with oral monotherapy (36%) and oral combination therapy (35%). Less than half of the patients had good glycemic control (HbA1c ≤ 6.5%). Half of the patients treated pharmacologically reported good compliance with treatment. Logistic regression analyses performed to identify factors associated with glycemic control showed that high body mass index (BMI) and poor compliance were the strongest predictors of poor HbA1c control (OR: 2.198 and 1.789, respectively, p < 0.05). In conclusion, in the course of managing diabetes, physicians and patients should attempt to improve compliance and lower BMI, which could lead to better glycemic control. PMID:19920948

    Bisphosphonates (BPs) are used to treat metabolic bone diseases, such as osteoporosis. In this study the occurrence of bisphosphonates-related osteonecrosis of the jaws (BRONJ) is reported in 25 patients who received BP therapy for osteoporosis with different drug schedules. From June 2005 to May 2009, 25 patients affected by BRONJ were observed. A history of oral surgery was reported for 18 patients (72%). Of the 22 patients treated by the authors, 20 (91%) recorded healing improvement with a mean follow-up of 16.6 months, with particular regard for those treated with oral surgery and laser applications (10/22, 45%) who were all characterised by complete mucosal healing over time. The risk of developing BRONJ in patients treated with BP for osteoporosis is lower than in cancer patients, but is not negligible. It is advisable for the prescribing physician to recommend a dental check-up prior to treatment, at least for patients who have not been to the dentist in the last 12 months. An early surgical and possible laser-assisted approach for patients who develop BRONJ is recommended. PMID:21163625

    There are limited data available on health-related quality of life (QoL) in patients with complex regional pain syndrome (CRPS). In the present study we examined QoL in 975 CRPS patients attending 6 different clinics in the Netherlands. QoL was assessed using the MOS 36-Item Short-Form Health Survey (SF-36) with the Mental Health Summary Score (MHS) and the Physical Health Summary Score (PHS) as dependent variables. The influences of gender, type of affected limb, disease duration, pain scores, CRPS severity and set of diagnostic criteria used were investigated. We found the lowest scores of QoL in the physical domains of the SF-36, with lower-limb CRPS patients reporting poorer results than patients with an affected upper limb. Influence of gender on QoL was not observed, and correlations of QoL with disease duration and the CRPS severity score were weak. Pain correlated moderately with QoL. In addition, patients fulfilling stricter diagnostic criteria (ie, the Budapest criteria) had lower QoL scores than patients fulfilling less strict criteria (ie, the Orlando criteria). We conclude that loss of QoL in CRPS patients is due mainly to reduced physical health. A comparison with data available from the literature shows that CRPS patients generally report poorer QoL than patients with other chronic pain conditions, particularly in the physical domains. Pain correlated moderately with QoL and therefore deserves ongoing attention by physicians. Finally, patients meeting the diagnostic Budapest criteria have lower QoL scores than patients meeting the Orlando criteria, highlighting the impact of different sets of criteria on population characteristics.

    Although Alzheimer's disease (AD) is a common cause of memory impairment and dementia in the elderly disturbed memory function is a widespread subjective and/or objective symptom in a variety of medical conditions. The early detection and correct distinction of AD from non-AD memory impairment is critically important to detect possibly treatable and reversible underlying causes. In the context of clinical research, it is crucial to correctly distinguish between AD or non-AD memory impairment in order to build homogenous study populations for the assessment of new therapeutic possibilities. The distinction of AD from non-AD memory impairment may be difficult, especially in mildly affected patients, due to an overlap of clinical symptoms and biomarker alterations between AD and certain non-AD conditions. This review aims to describe recent aspects of the differential diagnosis of AD and non-AD related memory impairment and how these may be considered in the presence of memory deficits.

    AIM: To determine the prevalence and significance of primary biliary cirrhosis (PBC)-specific autoantibodies in first-degree relatives (FDRs) of Greek PBC patients. METHODS: The presence of antimitochondrial antibodies (AMA) and PBC-specific antinuclear antibodies (ANA) were determined using indirect immunofluorescence assays, dot-blot assays, and molecularly based enzyme-linked immunosorbent assays in 101 asymptomatic for liver-related symptoms FDRs of 44 PBC patients. In order to specify our results, the same investigation was performed in 40 healthy controls and in a disease control group consisting of 40 asymptomatic for liver-related symptoms FDRs of patients with other autoimmune liver diseases namely, autoimmune hepatitis-1 or primary sclerosing cholangitis (AIH-1/PSC). RESULTS: AMA positivity was observed in 19 (only 4 with abnormal liver function tests) FDRs of PBC patients and none of the healthy controls. The prevalence of AMA was significantly higher in FDRs of PBC patients than in AIH-1/PSC FDRs and healthy controls [18.8%, 95% confidence interval (CI): 12%-28.1% vs 2.5%, 95% CI: 0.1%-14.7%, P = 0.01; 18.8%, 95% CI: 12%-28.1% vs 0%, 95% CI: 0%-10.9%, P = 0.003, respectively]. PBC-specific ANA positivity was observed in only one FDR from a PSC patient. Multivariate analysis showed that having a proband with PBC independently associated with AMA positivity (odds ratio: 11.24, 95% CI: 1.27-25.34, P = 0.03) whereas among the investigated comorbidities and risk factors, a positive past history for urinary tract infections (UTI) was also independently associated with AMA detection in FDRs of PBC patients (odds ratio: 3.92, 95% CI: 1.25-12.35, P = 0.02). CONCLUSION: In FDRs of Greek PBC patients, AMA prevalence is significantly increased and independently associated with past UTI. PBC-specific ANA were not detected in anyone of PBC FDRs.

    Twenty-seven patients with advanced stage refractory ovarian cancer were studied to determine if chronic stable cisplatin-related renal dysfunction was present. Medical histories were examined to determine the types of therapy previously received as well as the total previous platinum doses received that ranged from 200 to 2,100 mg/m2. Standard assessments of renal function were made prior to administering current chemotherapy or immunotherapy to the patient, which included 24-hour creatinine clearance, serum creatinine, and blood urea nitrogen (BUN). For patients with a 24-hour creatinine clearance of less than 60 mL/minute, serum creatinine was highly variable (range: 0.9 to 2.0 mg/dL) and was not related to the degree of diminution in the 24-hour creatinine clearance value. Conversely, for patients with a serum creatinine of less than 1.5, the 24-hour creatinine clearance values varied by almost three-fold, ranging between 46 and 120 mL/minute. Two patients with serum creatinines of less than 1 had creatinine clearances of less than 50 mL per minute. Similarly, BUN measurements did not correlate with 24-hour creatinine clearance values, and the 24-hour creatinine clearance value was not related to the total cumulative platinum dose. We conclude that patients who receive substantive doses of cisplatin may experience chronic stable cisplatin-related renal dysfunction and that serum creatinine cannot be relied on to assess the degree of renal compromise. In such patients, we recommended that the 24-hour creatinine clearance value should be used when medical management is influenced by renal function. PMID:1865503

    Mononuclear cells were obtained from 71 human immunodeficiency virus type 1 (HIV-1) seropositive subjects presenting and first visit either as asymptomatic or with minor symptoms and with CD4 lymphocytes greater than 550 per mm3 (group A, 35 patients) or as patients with AIDS, AIDS-related illnesses, or CD4 lymphocytes less than 400 per mm3 (group B, 36 patients). After 1-5 years of follow-up, 13 patients of group A had essentially retained their initial status (asymptomatics); the 22 others had suffered clinical or immunological deterioration (progressors). Frozen cells were thawed and submitted to lethal gamma-irradiation in vitro (4500 rads; 1 rad = 0.01 Gy) before they were cultured with normal phytohemagglutinin-stimulated lymphocytes to determine radiation-resistant HIV expression ex vivo (R-HEV). HIV antigenemia correlated with R-HEV values in 142 samples (r = 0.92, P less than 0.001) but was a less sensitive predictor of disease than R-HEV. R-HEV was detected in all specimens from patients with major AIDS-related illnesses or HIV-associated CD4 lymphopenia. In 77% of the progressors from group A, R-HEV detection preceded the onset of AIDS-associated disease or CD4 lymphopenia by 1 year (average). Conversely, R-HEV was low or was not detected in 36 sequential specimens from the 13 patients who remained asymptomatic over the following 2-5 years. Thus, persistently low HIV expression in vivo predicted a nondiseased state, whereas higher HIV expression levels seemed necessary for disease to occur. These data indicate that R-HEV is related to productive HIV infection in vivo, the latter acting as a determinant of AIDS-related illnesses. In view of this, measurement of HIV expression levels in the patient should be useful in antiviral efficacy trials.

    We give an effective field theory derivation, based on the running of Planck brane gauge correlators, of the large logarithms that arise in the predictions for low energy gauge couplings in compactified AdS}_5 backgrounds, including the one-loop effects of bulk scalars, fermions, and gauge bosons. In contrast to the case of charged scalars coupled to Abelian gauge fields that has been considered previously in the literature, the one-loop corrections are not dominated by a single 4D Kaluza-Klein mode. Nevertheless, in the case of gauge field loops, the amplitudes can be reorganized into a leading logarithmic contribution that is identical to the running in 4D non-Abelian gauge theory, and a term which is not logarithmically enhanced and is analogous to a two-loop effect in 4D. In a warped GUT model broken by the Higgs mechanism in the bulk,we show that the matching scale that appears in the large logarithms induced by the non-Abelian gauge fields is m_{XY}^2/k where m_{XY} is the bulk mass of the XY bosons and k is the AdS curvature. This is in contrast to the UV scale in the logarithmic contributions of scalars, which is simply the bulk mass m. Our results are summarized in a set of simple rules that can be applied to compute the leading logarithmic predictions for coupling constant relations within a given warped GUT model. We present results for both bulk Higgs and boundary breaking of the GUT gauge

    2013-01-01

    Background Drug-Related Problems (DRPs) commonly occur among type 2 diabetes mellitus (T2DM) patients. However, few studies have been performed on T2DM patients with dyslipidemia. This purpose of this study was to assess drug-related problems (DRPs) and factors associated with its occurrence. Methods The retrospective study involved 208 T2DM in-patients and out-patients with dyslipidemia, and was conducted at a tertiary hospital in Malaysia from January 2009 to December 2011. The identification and assessment of DRPs were based on the Pharmaceutical Care Network Europe (PCNE) tool version 5.01. The potentially inappropriate medication use in older adults was assessed based on the American Geriatrics Society updated Beers Criteria. Results A total of 406 DRPs were identified. Among these patients, 91.8% had at least one DRP, averaging 1.94 ± 1.10 problems per patient. The majority of T2DM patients with dyslipidemia (91.8%) had at least one DRP. The most frequent types of DRP were potential drug-drug interaction (18.0%), drug not taken or administered (14.3%) and insufficient awareness of health and diseases (11.8%). Anti-hypertensive, lipid-modifying and anti-diabetic agents were the drug classes that were most likely to be associated with DRPs. Male gender, renal impairment, polypharmacy and poor lipid control were factors that were significantly associated with DRP in diabetic dyslipidemia patients. Conclusion Early identification of DRPs and factors associated with them are essential to prevent and resolve DRPs in T2DM patients with dyslipidemia. PMID:24341672

    We report the results of 84 patients with ALL after related (n = 46) or unrelated (n = 38) allogeneic SCT. Mean recipient age was 23 years (range: 1-60) and median follow-up was 18 months (range: 1-133). Forty-three patients were transplanted in CR1; 25 in CR2 or CR3; four were primary refractory; four in PR; eight in relapse. The conditioning regimen consisted of TBI/VP16/CY (n = 76), TBI/VP16 (n = 2), TBI/CY (n = 2), Bu/VP16/CY (n = 4). The OS at 3 years was 45% (44% unrelated, 46% related). Univariate analysis showed a significantly better OS for patients <18 years (P=0.03), mismatched sex-combination (P = 0.03), both with a stronger effect on increasing OS after unrelated SCT. Factors decreasing TRM were patient age <18 years (P = 0.004), patient CMV-seronegativity (P = 0.014), female recipient (P = 0.04). There was no significant difference in TRM and the relapse rate was similar in both donor type groups. Multivariate analysis showed that factors for increased OS which remained significant were mismatched sex-combination (RR: 0.70,95% CI: 0.51-0.93, P = 0.015), patient age < 18 years (RR: 0.66, 95% CI: 0.47-0.93, P = 0.016). A decreased TRM was found for female patients (RR: 0.56, 95% CI: 0.33-0.98, P=0.042), negative CMV status of the patient (RR: 0.57, 95% CI: 0.36-0.90, P = 0.015). Unrelated stem cell transplantation for high-risk ALL patients with no HLA-compatible family donor is justifiable.

    Many patients with cleft palate deformities worldwide receive treatment at a later age than is recommended for normal speech to develop. The outcomes after late palate repairs in terms of speech and quality of life (QOL) still remain largely unstudied. In the current study, questionnaires were used to assess the patients' perception of speech and QOL before and after primary palate repair. All of the patients were operated at a cleft center in northeast India and had a cleft palate with a normal lip or with a cleft lip that had been previously repaired. A total of 134 patients (7-35 years) were interviewed preoperatively and 46 patients (7-32 years) were assessed in the postoperative survey. The survey showed that scores based on the speech handicap index, concerning speech and speech-related QOL, did not improve postoperatively. In fact, the questionnaires indicated that the speech became more unpredictable (P < 0.01) and that nasal regurgitation became worse (P < 0.01) for some patients after surgery. A total of 78% of the patients were still satisfied with the surgery and all of the patients reported that their self-confidence had improved after the operation. Thus, the majority of interviewed patients who underwent late primary palate repair were satisfied with the surgery. At the same time, speech and speech-related QOL did not improve according to the speech handicap index-based survey. Speech predictability may even become worse and nasal regurgitation may increase after late palate repair, according to these results.

    Serrated polyposis syndrome is associated with an increased colorectal cancer risk. Although the underlying genetic cause of the condition is unknown, first-degree relatives of patients with serrated polyposis have an increased risk for colorectal cancer compared with the general population. This suggests an inheritable component. Since other hereditary polyposis syndromes are often associated with an expanded extracolonic tumour spectrum, our aim was to determine the extra colonic cancer risks for patients with serrated polyposis and their first-degree relatives and compare these risks with the general population. Serrated polyposis index patients from 5 medical centres were included. Demographic data concerning age, sex and reported malignancies were ascertained by reviewing medical charts and histopathology reports. Family history was obtained by examining pedigree records from the department of Clinical Genetics. Incidence rates of extracolonic malignancies were compared with the general population through a person-year analysis, adjusted for age and sex. Population-based incidence data were derived from the Eindhoven Cancer Registry. A total of 105 patients with serrated polyposis and 341 first-degree relatives were included. Among the patients with serrated polyposis, 9 extracolonic cancers were observed, compared to 13 expected malignancies in the general population (RR 0.69 95% CI 0.36-1.33; p = 0.27). Among the first-degree relatives, 44 extracolonic malignancies were observed, compared to 48 expected malignancies (RR 0.92 95% CI 0.69-1.24; p = 0.60). In this study, the overall incidence of extracolonic malignancies in patients with serrated polyposis and their first-degree relatives was not increased. Large international studies are required to confirm these results.

    Some neuropsychological abilities, particularly those affecting memory, attention and executive function, are impaired amongst both schizophrenic patients and their unaffected relatives, implying that these deficits are at least partly genetic in origin. However neuropsychological performance can be altered by medication, and has rarely been examined in first onset, drug naive patients. The objective of this study was to determine whether selected neurocognitive abilities are impaired in first-onset schizophrenic patients and their relatives compared to controls. We examined attention and speed of information processing, memory and learning, verbal function, visuoconstructive abilities and executive function in 207 first-episode schizophrenic patients (163 of whom were drug naïve), 322 of their first-degree relatives and 133 unrelated normal controls. The data were subjected to multilevel modeling to compare neurocognitive performance between schizophrenic probands, relatives and controls while taking into account potential correlations among members of the same family; age, gender, and years of education were included as covariates. Of the three groups, schizophrenic patients performed poorest at all neuropsychological tests, suggestive of a broad range of neurocognitive deficits. Their first-degree relatives showed a narrower pattern of poor performance at Digit Symbol, Digit Span, Trail Making, Verbal Fluency test, Tower of Hanoi, and WCST-M tests. Our findings show that selected neurocognitive deficits especially attention and executive function are impaired in the families of schizophrenic patients. These patterns of neurocognitive deficits may represent "endophenotypes" denoting varying degrees of vulnerability to schizophrenia and may be of value in future molecular genetic studies.

    Variability in daily blood pressure (BPV) recorded 24-h ambulatory blood pressure monitoring (ABPM) is known to be related to left ventricular hypertrophy and an increased incidence of cardiovascular events in hypertensive patients. The aim of this study was to evaluate whether left atrium dimension, which increases early in hypertensive subjects, was related to BPV in a group of 167 drug-naive patients (100M/67F, age: 46±11yr). The patients were chosen among those consecutively sent by their general practitioners to confirm the existence of arterial hypertension and afterwards diagnosed as hypertensive (mean 24-h ABPM ⩾130/80 mm Hg). In each patient, the left atrial posteroanterior diameter index for height (LADi) and the left ventricular mass standardized for body surface area (LVMi) were measured using standardized echocardiographic methods. BPV was calculated as the weighted mean of daytime and nighttime systolic and diastolic blood pressure s.d.'s (ws.d.), according to the formula ws.d.=[(daytime s.d. × 10)+nighttime s.d. × 6)]/16. An increase in left atrial dimension (LADi>24 mm m(-1)) was present in 36 patients (21.6% of the total population). In a univariate regression, LVMi was significantly related to systolic BPV (r=0.24; P=0.02) only in men, whereas LADi was significantly related to both systolic and diastolic BPV in both genders. After adjusting for sex, age, BMI, heart rate, diastolic function and estimated glomerular filtration rate, both systolic and diastolic BPV remained significantly related to LADi (P=0.02 for both) but not to LVMi. In conclusion, this study suggests that BVP, as measured as BPws.d., is significantly and independently associated with increased LADi in newly diagnosed, treatment-naive hypertensive patients.

    Drug discovery efforts in Alzheimer's disease (AD) have been directed in the last ten years to develop "disease-modifying drugs" able to exert neuroprotective effects in an early phase of AD pathogenesis. Unfortunately several candidate disease-modifying drugs have failed in Phase III clinical trials conducted in mild to moderate AD for different methodological difficulties, such as the time course of treatment in relation to development of disease as well as the appropriate use of validated biological and neuropsychological markers. Mild cognitive impairment (MCI) has been considered a precursor of AD. Much effort is now directed to identify the most appropriate and sensitive markers which can predict the progression from MCI to AD, such as neuroimaging markers (e.g. hippocampal atrophy and amyloid positron emission tomography imaging), cerebrospinal fluid markers (i.e. association of elevated tau with low levels of amyloid β -peptide(1-42) and neuropsychological markers (i.e. episodic memory deficits and executive dysfunction). Recent studies demonstrate that the combination of these different biomarkers significantly increases the chance to predict the conversion into AD within 24 months. These biomarkers will be essential in the future to analyze clinical efficacy of disease-modifying drugs in MCI patients at high risk to develop AD. In the present review we analyze recent evidence on the combination of neuropsychological and biological markers in AD as a new tool to track disease progression in early AD as well as the response to disease-modifying drugs.

    Herniated discs usually occur in middle aged persons. For some the pain is so serious that an operation is necessary. Yet despite modern micro-surgical methods for operations, approximately one-third of the patients continue to report ongoing limitations. The reasons for insufficient success of therapy however lie not only in the illness as such. This study is intended to examine the changes in the subjective success parameters of pain-related impairment and the ability to function in herniated disc patients during rehabilitation. Using multivariate analyses, the influence of sociodemographic, illness-specific, work-related and mental variables on changes in goal variables is shown. 214 herniated disc patients were interviewed before the operation, after post-operative therapy, and six months after surgery. Before their operation, herniated disc patients experienced a severe limitation of activity and ability in everyday function due to pain. About three-fourth of the patients experienced significant improvement in both variables after the operation and post-operative therapy. The influence factors for a successful therapy outcome were male gender and higher educational level. Risk factors were increasing age, a desire for a pension, severe illness symptoms and severe pre-operative depression. In addition to somatic therapy, higher risk patients should receive psychological or social and employment counselling as a support to post-operative therapy. PMID:18188804

    The incidence of second primary malignancies (SPMs) in Japanese patients with myeloma or myeloma-related diseases was studied by using the Kansai Myeloma Forum (KMF) database registered from November 2012 to March 2015. We studied 1,571 cases. Hematologic malignancies were documented in 10 patients, and solid tumors in 36 during this period. The cumulative 5-year incidence was estimated to be 1.0% for hematological malignancies and 3.7% for solid tumors. In the patients with smoldering myeloma or MGUS without treatment, solid tumors but not hematologic malignancies developed, though the cumulative incidence of each malignancy did not differ significantly from that in patients receiving treatment. Although statistical analysis showed that treatment with melphalan, bortezomib, lenalidomide, or thalidomide had no effect on the occurrence of hematological malignancies, lenalidomide administration was more frequent in the patients with solid tumors. To evaluate the SPMs in myeloma or myeloma-related diseases more accurately, accumulation of a larger number of patients and longer observation are needed. PMID:27498726

    We studied 199 inpatients and outpatients at a public psychiatric hospital to clarify the factors related to outcome following psychiatric care for substance-related disorder (SRD), and we discuss approaches for more effective community care in the future. The percentage of patients who discontinued treatment was 33.7%, suggesting that creation of a follow-up system for continuing outpatient care is an urgent task. Women were 35% more likely higher to discontinue treatment than men. Those with solvent dependence were 12% and 7.32 times more likely, respectively, to discontinue treatment than those with alcohol dependence. Those without complications were 2.24 times more likely than those with complications to discontinue treatment. Divorced patients were 18% and 6.35 times more likely, respectively, to discontinue treatment than married patients. There is insufficient support for patients with solvent dependence, and we observed that patients tended to have little motivation to stop using drugs or alcohol until physical complications occurred. Among the many divorced patients, desire for treatment was weak following breakdown of the family. The present findings suggest the importance of comprehensive efforts to treat substance use disorder at specialist medical institutions.

    The percentage of change from baseline in low-density lipoprotein (LDL) cholesterol after the addition of ezetimibe 10 mg to atorvastatin 40 mg was compared with uptitration to atorvastatin 80 mg. In this multicenter, double-blind, parallel-group study, adult hypercholesterolemic patients using atorvastatin 40 mg/day were randomly assigned to atorvastatin 40 mg plus ezetimibe 10 mg or uptitration to atorvastatin 80 mg. After 6 weeks of treatment, compared with atorvastatin 80 mg, atorvastatin 40 mg plus ezetimibe significantly reduced the primary end point of LDL cholesterol by -27% versus atorvastatin 80 mg by -11% (p <0.001), as well as significantly reduced non-high-density lipoprotein cholesterol, apolipoprotein B, total cholesterol, and triglycerides significantly more than atorvastatin 80 mg (all p <0.001). Percentages of change in high-sensitivity C-reactive protein, high-density lipoprotein cholesterol, and apolipoprotein A-I were similar between groups. Significantly more patients treated with atorvastatin 40 mg plus ezetimibe reached LDL cholesterol <70 mg/dl versus patients treated with atorvastatin 80 mg (74% vs 32%; p <0.001). Safety and tolerability profiles and incidence of liver and muscle adverse experiences were generally similar between groups. In conclusion, these results showed that adding ezetimibe to atorvastatin 40 mg was significantly more effective than uptitrating to atorvastatin 80 mg at lowering LDL cholesterol and other lipid parameters. Both treatments were generally well tolerated (clinical trial no. NCT00276484).

    We compared 25 patients with multiple sclerosis (MS) and 24 normal controls on a test of free recall of words. Some lists contained words that were all unrelated, while in others the intermediary words were semantically related. In another set, the mid-list words were repeated across the lists, or, in addition to the repetition, were semantically associated. Immediate recall was assessed using these lists. Delayed recall was assessed using different lists (delay-unrelated and delay-related) after distractor tasks. Recency was not affected in MS patients, but the primacy effect was lower than in controls, this effect being interpreted as due to a deficiency in articulatory rehearsal. The delay interval after each list abolished recency in both groups and resulted in impaired recall in MS patients. However the patients, like the controls, benefited from semantic relations in the middle of the lists and from spaced repetition of words across the lists, in either immediate and delayed recall. The enhancing effects of word relatedness and of spaced repetition are seen as being due to automatic processes preserved in MS patients.

    Objective Cancer treatment is reported to be stressful, and patients diagnosed with hematologic cancers often exhibit higher levels of anxiety and emotional distress than individuals with other malignancies. Management of these symptoms in patients with hematologic cancer presents significant challenges, as many of them are in and out of the hospital while undergoing high dose chemotherapy. Oncology patients use complementary modalities such as therapeutic massage in an attempt to alleviate disease and treatment-related symptoms, including anxiety and emotional distress. In the current study, the feasibility of a novel massage intervention delivered over the continuum of care, as well as assessment of the immediate and cumulative effects of massage, was examined in patients with acute myelogenous leukemia. Methods A mixed-methods, unmasked, prospective, randomized study was conducted with two groups: a usual care alone control group and a massage therapy intervention plus usual care group. Results Significant improvements in levels of stress and health-related quality of life were observed in the massage therapy group versus the usual care alone group, after adjusting for anxiety level, including both immediate and cumulative effects of massage. Conclusions While the findings of the current study regarding acceptability, feasibility, and potential efficacy of therapeutic massage as a complementary health-enhancing intervention in patients diagnosed with acute myelogenous leukemia are very promising, the relatively small size of the study sample limits generalizability.

    Alu and LINE-1 elements are retrotransposons with a ubiquitous presence in the human genome that can cause genomic instability, specifically relating to telomere length. Genotoxic agents may induce methylation of retrotransposons, in addition to oxidative DNA damage in the form of 8-hydroxy-2'-deoxyguanosine (8-OHdG). Methylation of retrotransposons induced by these agents may contribute to biliary atresia (BA) etiology. Here, we investigated correlations between global methylation, 8-OHdG, and relative telomere length, as well as reporting on Alu and LINE-1 hypomethylation in BA patients. Alu and LINE-1 hypomethylation were found to be associated with elevated risk of BA (OR = 4.07; 95% CI: 2.27-7.32; P < 0.0001 and OR = 3.51; 95% CI: 1.87-6.59; P < 0.0001, respectively). Furthermore, LINE-1 methylation was associated with liver stiffness in BA patients (β coefficient = -0.17; 95% CI: -0.24 to -0.10; P < 0.0001). Stratified analysis revealed negative correlations between Alu and LINE-1 methylation and 8-OHdG in BA patients (P < 0.0001). In contrast, positive relationships were identified between Alu and LINE-1 methylation and relative telomere length in BA patients (P < 0.0001). These findings suggest that retrotransposon hypomethylation is associated with plasma 8-OHdG and telomere length in BA patients. PMID:27243754

    Intermediate endophenotypes emerge as an important concept in the study of schizophrenia. Although research on phenotypes mainly investigated cognitive, metabolic or neurophysiological markers so far, some authors also examined the motor behavior anomalies as a potential trait-marker of the disease. However, no research has investigated social motor coordination despite the possible importance of its anomalies in schizophrenia. The aim of this study was thus to determine whether coordination modifications previously demonstrated in schizophrenia are trait-markers that might be associated with the risk for this pathology. Interpersonal motor coordination in 27 unaffected first-degree relatives of schizophrenia patients and 27 healthy controls was assessed using a hand-held pendulum task to examine the presence of interpersonal coordination impairments in individuals at risk for the disorder. Measures of neurologic soft signs, clinical variables and neurocognitive functions were collected to assess the cognitive and clinical correlates of social coordination impairments in at-risk relatives. After controlling for potential confounding variables, unaffected relatives of schizophrenia patients had impaired intentional interpersonal coordination compared to healthy controls while unintentional interpersonal coordination was preserved. More specifically, in intentional coordination, the unaffected relatives of schizophrenia patients exhibited coordination patterns that had greater variability and in which relatives did not lead the coordination. These results show that unaffected relatives of schizophrenia patients, like the patients themselves, also present deficits in intentional interpersonal coordination. For the first time, these results suggest that intentional interpersonal coordination impairments might be a potential motor intermediate endophenotype of schizophrenia opening new perspectives for early diagnosis.

    OBJECTIVE—To determine the possibility of recording "cognitive" event related potentials (ERPs) in locked-in patients and therefore to determine whether ERPs can have a role in differential diagnosis of coma.
METHODS—ERPs to classic auditory or visual "odd ball paradigms" were recorded three to four days, seven to eight days, and 30 to 60days after admission to the intensive care unit, in four patients affected by basilar artery thrombembolism resulting in locked-in syndrome. Two patients (one 32 year old man, one 31 year old woman) could move the eyes laterally and vertically spontaneously and on command. One patient (a 39 year old man) had a "one and half syndrome", one patient (a 40 year old woman) could only elevate the left eyelid and eye. Results were compared with data from 30 age matched controls. In the last recording session a letter recognition paradigm was applied, in which ERPs were produced by the identification of letters forming a word. Results were compared with five age matched controls. Brainstem lesions extending to the pontomesencephalic junction were found on MRI and CT.
RESULTS—ERPs to the oddball paradigms were recorded in three patients in the first recording session, in all patients in the second recording session. Latency, amplitude, and topographic distribution of ERP components were inside normal limits. With the letter recognition paradigm the patients could emit a P3 component to correspond with target letters, with the same margin of error as controls.
CONCLUSION—It is possible to record ERPs in patients with locked-in syndrome shortly after the acute ischaemic lesion, and therefore to assess objectively cognitive activities. Furthermore the letter recognition paradigm could be implemented to facilitate linguistic communication with patients with locked-in syndrome.

    To the authors' knowledge there are relatively few studies that try to answer this topic: "Are humans able to add value to computer-generated forecasts and warnings ?". Moreover, the answers are not always positive. In particular some postprocessing method is competitive or superior to human forecast (see for instance Baars et al., 2005, Charba et al., 2002, Doswell C., 2003, Roebber et al., 1996, Sanders F., 1986). Within the alert system of ARPA Piemonte it is possible to study in an objective manner if the human forecaster is able to add value with respect to computer-generated forecasts. Every day the meteorology group of the Centro Funzionale of Regione Piemonte produces the HQPF (Human QPF) in terms of an areal average for each of the 13 regional warning areas, which have been created according to meteo-hydrological criteria. This allows the decision makers to produce an evaluation of the expected effects by comparing these HQPFs with predefined rainfall thresholds. Another important ingredient in this study is the very dense non-GTS network of rain gauges available that makes possible a high resolution verification. In this context the most useful verification approach is the measure of the QPF and HQPF skills by first converting precipitation expressed as continuous amounts into ‘‘exceedance'' categories (yes-no statements indicating whether precipitation equals or exceeds selected thresholds) and then computing the performances for each threshold. In particular in this work we compare the performances of the latest three years of QPF derived from two meteorological models COSMO-I7 (the Italian version of the COSMO Model, a mesoscale model developed in the framework of the COSMO Consortium) and IFS (the ECMWF global model) with the HQPF. In this analysis it is possible to introduce the hypothesis test developed by Hamill (1999), in which a confidence interval is calculated with the bootstrap method in order to establish the real difference between the

    Primary contact health care practitioners can play an important role in work-related musculoskeletal disorders (WRMSDs) by recognizing and addressing occupational health issues. It is important to recognize ergonomics as a possible factor in patient health and recovery. A case is presented of a 36-year-old male suffering from neck and trapezius pain. Ergonomic factors at his musculoskeletal disorder. Conservative care and ergonomic changes to his workstation produced positive results leading to a full recovery. Practitioners should not ignore the possibility that the workplace may be a contributing factor in patients presenting with musculoskeletal complaints. A through patient history is the key to determining if musculoskeletal disorders are work-related. ImagesFigure 1Figure 2AFigure 2B

    We describe a case of acute liver failure in a patient with advanced hepatocellular carcinoma related to nonalcoholic steatohepatitis during sorafenib treatment. A 74-year-old man with diabetes mellitus and hypertension was diagnosed with hepatocellular carcinoma associated with fatty liver. Three weeks after sorafenib therapy, at Eastern Cooperative Oncology Group performance status 3, he developed jaundice, general weakness, flapping tremor, nausea, and anorexia. Sorafenib was stopped: laboratory tests showed a relevant elevation of transaminases suggesting diagnosis of acute hepatitis. During hospital admission, the patient died of liver failure. Sorafenib is the first successful target therapy effective for advanced hepatocellular carcinoma. The most common adverse events are fatigue, hand-foot skin reaction, skin rash/desquamation, diarrhea, and hypertension, whereas liver dysfunction is uncommon. To our knowledge, this is the first patient reported in the literature with hepatocellular carcinoma related to nonalcoholic steatohepatitis who died of rapid worsening of liver function during sorafenib treatment.

    Patient positioning during surgery can have profound short and long term implications for the patient. Each position carries some degree of risk to the patient, which is magnified in prolonged operations, surgeries performed under general anesthesia and when position manipulations are required in order to gain best surgical access. Prevention is the mainstay of the management of positioning. Therefore, it is crucial that all operating room personnel will be familiar with the different surgical positions and their general and specific position-related injury potential. It is also important that these complications are diagnosed promptly and managed appropriately in the post-operative period. The purpose of the following review is to summarize the positioning-related complications, in particular peripheral nerve injuries, and emphasize correct positioning recommendations and preventive measures.

    Doing a double Wick rotation in the world sheet theory of the light cone AdS5×S(5) superstring results in an inequivalent, so-called mirror theory that plays a central role in the field of integrability in the AdS-CFT correspondence. We show that this mirror theory can be interpreted as the light cone theory of a free string on a different background. This background is related to dS5×H(5) by a double T-duality, and has hidden supersymmetry. The geometry can also be extracted from an integrable deformation of the AdS5×S(5) sigma model, and we prove the observed mirror duality of these deformed models at the bosonic level as a byproduct. While we focus on AdS5×S(5), our results apply more generally. PMID:25615306

    This literature review aims to evaluate the epidemiologic profile of patients with rheumatoid arthritis (RA) that developed a bisphosphonate-related osteonecrosis that affect the jaws (BRONJ), including demographic aspects, as well as clinical and therapeutic issues. A search of PUBMED/MEDLINE, Scopus, and Cochrane databases from January 2003 to September 2011 was conducted with the objective of identifying publications that contained case reports regarding oral BRONJ in RA patients. Patients with RA who develop oral BRONJ are usually women above 60 years taking steroids and long-term alendronate. Most of them have osteoporosis, and lesions, triggered by dental procedures, are usually detected at stage II in the mandible. Although there is no accepted treatment protocol, these patients seem to have better outcomes with conservative approaches that include antibiotic therapy, chlorhexidine, and drug discontinuation.

    Few investigators have compared health-related quality of life (HRQOL) in heart failure (HF) patients from different countries. The purposes of this study were to compare HRQOL between American (n=87) and Taiwanese (n=88) HF patients and to determine factors associated with HRQOL in both groups. In this cross-sectional survey, HRQOL was measured using the Minnesota Living with Heart Failure Questionnaire. American patients rated their HRQOL worse than did Taiwanese patients. Socio-demographics, disease severity, and symptom severity were associated with HRQOL, accounting for 42.4% of the variance in HRQOL in Americans and 57.3% in Taiwanese. Symptom severity was the most important predictor of HRQOL in both groups. Interventions targeting symptom severity could improve HF patients’ HRQOL. PMID:20371738

    Background & Aims Barrett’s esophagus (BE) affects approximately 10% of patients with chronic gastroesophageal reflux disease (GERD). Patients with BE are at risk for reduced health-related quality of life (HRQoL) associated with GERD, in addition to the potential psychosocial stress of carrying a diagnosis of a premalignant condition with a risk of esophageal adenocarcinoma (EAC). We sought to systematically review the published literature on HRQoL of patients with BE. Methods We searched PubMed, PsycINFO, and CINAHL for relevant clinical trials using a defined search strategy. We also manually searched relevant scientific meeting abstracts and related articles in bibliographies. Eligible articles were case series, cohort studies, or clinical trials that included one or more measures of HRQoL and/or quantitatively assessed burden of disease in patients with BE. Effect sizes were calculated when possible. Results Our initial search identified 95 articles. After 2 physician review, 25 articles met inclusion criteria. Data demonstrate that BE is associated with a significant decrement in HRQoL as measured by both generic and disease-targeted instruments. In addition, patients with BE are at risk for psychological consequences such as depression, anxiety and stress, which may be related to their increased risk of EAC. Compared to subjects with GERD alone or the general population, a diagnosis of BE also leads to increased healthcare utilization and spending. Conclusions Barrett’s esophagus compromises multiple facets of patients’ quality of life. Physicians and researchers should incorporate patient reported outcomes data including HRQoL measures when treating or studying patients with Barrett’s esophagus. PMID:19281858

    Hepatitis C virus (HCV) infection is associated with oxidative stress and vitamin A possesses antioxidant activity. The objective of the present study was to investigate vitamin A nutritional status in chronic hepatitis, liver cirrhosis and hepatocellular carcinoma (HCC), according to biochemical, functional and dietetic indicators correlating these findings with liver function, liver damage and death. Vitamin A nutritional status was analysed by serum retinol levels, dietetic indicators and functional indicators. A total of 140 patients with HCV-related liver disease were enrolled. Vitamin A deficiency was detected in 54·3 % of all patients, and there was a progressive drop in serum retinol levels from chronic hepatitis C patients towards cirrhosis and HCC patients. Increased total bilirubin, liver transaminases and prothrombin time, presence of hepatic encephalopathy and ascites were related to reduced serum retinol levels, and values ≤ 0·78 μmol/l of serum retinol were associated with liver-related death. A high prevalence of inadequate intake of vitamin A was observed in all stages of chronic liver disease. The functional indicator was not an adequate parameter for evaluating the vitamin A nutritional status. Therefore, serum retinol concentration is related to severity of the disease, liver complications and mortality. The effectiveness of nutritional counselling and measures of intervention in this group in improving vitamin A nutritional status should be examined further in a controlled study. PMID:21736776

    In the Hungarian law, non-burial interventions on cadavers are regulated only by the health law and, therefore, other scientific examinations are theoretically not allowed. Only the international ethical code of museums is used in certain cases. Numerous cultures consider this practice as the mutilation of the cadaver. Beyond this and the criminal forms of mutilation, the medical interventions (trial and training) are also appropriate to hurt the dignity of the dead. As a counterweight, the consent of the patient or his/her relatives is needed for post-mortem interventions. This study presents the Hungarian legislation in which the deceased is a 'patient', and the special enforcement of patients' rights takes place in relation to the body. The relatives have many rights concerning autopsy, and the anatomy institutes are also regulated. The presumption of opting-out is used for organ harvesting; objection is accepted only from the patient. Medical data of the deceased are strictly protected, but there are no obstacles to the interests of the relatives. Graduate and postgraduate medical education pays only little attention to these issues, and the legislation is not in line with the present expectations and possibilities, so that it would be advisable to reconsider the full spectrum of the problem.

    Dichotic listening (DL) has been used as a tool to investigate possible left cerebral dysfunction in schizophrenia. However, the wide range of DL tests (e.g., words, emotions, sentences) as well as patient groups ("heterogeneity") has introduced several confounders. Assessing relatives of patients with schizophrenia may overcome some of these problems, and may be more useful in determining if loss of functional cerebral laterality in schizophrenia is a state or a trait phenomenon. The fused consonant-vowel DL test was administered to 114 subjects: 20 individuals with familial schizophrenia, 42 of their healthy relatives, and 52 healthy volunteers. We did this to investigate whether the normal language processing asymmetry-a right ear advantage (REA)-is present, and whether it could serve as a marker for genetic liability. General performance accuracy level was lower in schizophrenia patients and their relatives but the expected REA was present in all groups. Adjusting for age, accuracy, and obligate status made no difference. In conclusion, familial schizophrenic patients and their relatives have normal REA and hearing laterality on the fused DL test.

    Background The purpose of the study was to evaluate some of the hormones in patients with chronic liver disease and cirrhosis. Methods The men patients with chronic hepatitis B (Group 1), liver cirrhosis secondary to hepatitis B (Group 2), were included in this study. Additionally, a control group of healthy volunteers (Group 3) was formed. We investigated serum levels of Follicle-stimulating hormone (FSH), Luteinizing hormone (LH), Total testosterone (T. TES), Free-testosterone (F. TES), Estradiol (E2), Androstenedione (ANDR), Dihydroepiandrosterone (DHEA), Progesterone (PPOGES), Prolactin (PRL), Sex hormone binding protein (SHGB) were measured by radioimmunoassay and chemiluminescent immunoassay methods. Result A total of 73 patients with chronic liver disease and cirrhosis were included in the study. Patients were grouped as cirrhosis (n = 28), chronic hepatitis B (n = 41) according to the type of their chronic liver disease. Serum F.TEST level in patient groups (group 1, group 2) was found to be lower than control group (P = 0.045, P = 0.047). Serum LH value was found to be higher in patient group (group 2) than control group (P = 0.048). Serum estradiol was higher in the group 2 compared to the control group (P = 0.046). Conclusions The described disturbances of some of the observed hormones (LH, E2, F. TES) are complex, particularly in their relationship by which the clinical picture of the hepatitis B related cirrhotic patients and chronic liver disease can be explained.

    We study three-dimensional consistent truncations of type IIB supergravity which admit warped AdS3 solutions. These theories contain subsectors that have no bulk dynamics. We show that the symplectic form for these theories, when restricted to the non-dynamical subsectors, equals the symplectic form for pure Einstein gravity in AdS3. Consequently, for each consistent choice of boundary conditions in AdS3, we can define a consistent phase space in warped AdS3 with identical conserved charges. This way, we easily obtain a Virasoro × Virasoro asymptotic symmetry algebra in warped AdS3; two different types of Virasoro × Kač-Moody symmetries are also consistent alternatives.

    Background Aspiration of oral or gastric contents into the larynx and lower respiratory tract is a common problem in acute stroke patients, which significantly increases the incidence of acute respiratory distress syndrome (ARDS). However, little is known about the clinical characteristics of aspiration-related ARDS in acute stroke patients. Methods Over 17-month period a retrospective cohort study was done on 1495 consecutive patients with acute stroke. The data including demographic characteristics, clinical manifestations, laboratory examinations, chest imaging, and hospital discharge status were collected to analysis. Results Aspiration-related ARDS was diagnosed in 54 patients (3.6%). The most common presenting symptom was tachypnea (respiratory rate ≥25 breaths/min) in 50 cases. Computed tomography (CT) images usually demonstrated diffuse ground-glass opacities (GGOs) and inhomogeneous patchy consolidations involving the low lobes. Age, NIHSS score, GCS score, dysphagia, dysarthria, hemoglobin concentration, serum aspertate aminotransferase (AST), serum albumin, serum sodium, and admission glucose level were independently associated with aspiration-related ARDS (odds ratio (OR) 1.05, 95% confidence interval (CI) (1.04–1.07); OR 2.87, (2.68–3.63); OR 4.21, (3.57–5.09); OR 2.18, (1.23–3.86); OR 1.67, (1.31–2.14); OR 2.31, (1.11–4.84); OR 1.68, (1.01–2.80); OR 2.15, (1.19–3.90); OR 1.92, (1.10–3.36) and OR 1.14, (1.06–1.21) respectively). Conclusions Aspiration-related ARDS frequently occurs in acute stroke patient with impairment consciousness. It is advisable that performing chest CT timely may identify disease early and prompt treatment to rescue patients. PMID:25790377

    Background Breast cancer is the most common type of cancer in women in the developed world. As a result of breast cancer treatment, many patients suffer from serious complaints in their arm and shoulder, leading to limitations in activities of daily living and participation. In this systematic literature review we present an overview of the adverse effects of the integrated breast cancer treatment related to impairment in functions and structures in the upper extremity and upper body and limitations in daily activities. Patients at highest risk were defined. Methods and Findings We conducted a systematic literature search using the databases of PubMed, Embase, CINAHL and Cochrane from 2000 to October 2012, according to the PRISMA guidelines. Included were studies with patients with stage I–III breast cancer, treated with surgery and additional treatments (radiotherapy, chemotherapy and hormonal therapy). The following health outcomes were extracted: reduced joint mobility, reduced muscle strength, pain, lymphedema and limitations in daily activities. Outcomes were divided in within the first 12 months and >12 months post-operatively. Patients treated with ALND are at the highest risk of developing impairments of the arm and shoulder. Reduced ROM and muscle strength, pain, lymphedema and decreased degree of activities in daily living were reported most frequently in relation to ALND. Lumpectomy was related to a decline in the level of activities of daily living. Radiotherapy and hormonal therapy were the main risk factors for pain. Conclusions Patients treated with ALND require special attention to detect and consequently address impairments in the arm and shoulder. Patients with pain should be monitored carefully, because pain limits the degree of daily activities. Future research has to describe a complete overview of the medical treatment and analyze outcome in relation to the treatment. Utilization of uniform validated measurement instruments has to be

    Context: According to the american medical association (AMA) and the national institutes of health (NIH), the recommended readability of patient education materials should be no greater than a sixth-grade reading level. The online patient education information produced by the american academy of orthopaedic surgeons (AAOS) may be too complicated for some patients to understand. This study evaluated whether the AAOS’s online trauma-related patient education materials meet recommended readability guidelines for medical information. Evidence Acquisition: Ninety-nine articles from the “Broken Bones and Injuries” section of the AAOS-produced patient education website, orthoinfo.org, were analyzed for grade level readability using the Flesch-Kincaid formula, a widely-used and validated tool to evaluate the text reading level. Results for each webpage were compared to the AMA/NIH recommended sixth-grade reading level and the average reading level of U.S. adults (eighth-grade). Results: The mean (SD) grade level readability for all patient education articles was 8.8 (1.1). All but three of the articles had a readability score above the sixth-grade level. The readability of the articles exceeded this level by an average of 2.8 grade levels (95% confidence interval, 2.6 - 3.0; P < 0.0001). Furthermore, the average readability of the articles exceeded the average reading skill level of U.S. adults (eighth grade) by nearly an entire grade level (95% confidence interval, 0.6-1.0; P < 0.0001). Conclusions: The majority of the trauma-related articles from the AAOS patient education website have readability levels that may make comprehension difficult for a substantial portion of the patient population.

    The availability of safe and effective factor replacement therapies, in persons with haemophilia (PWH), has in some countries answered the basic need for treatment of these patients. The findings suggest that adult patients who have always been on prophylaxis reported significantly better physical functioning, and thus better quality of life. This study is designed to evaluate the QoL in adult PWH, by focusing on social determinants of QoL and their relationship with health-related dimensions, in Tabriz, Iran. The survey instrument was a self-report 36 items questionnaire, 'A36 Hemofilia - QoL', which is a disease-specific questionnaire for the assessment of the health-related QoL in adults living with haemophilia. A total of 100 haemophilia A and B patients, aged over 17 years participated in this study within 1 year. QoL total score was 71.88 (±26.89 SD). Patients who treat in our Hemophilia Treatment Center, had better QoL score (P = 0.000), and education has a significant impact on the social aspects of QoL (P = 0.18). The QoL was very poor in urban area in contrast to patients who lived in the city (54.45 vs. 74.21 respectively). Single patients have a better QoL than married patients (76.56 vs. 68.50 respectively). Our results showed that low education and lack of awareness of the diseases among PWH lead to reduce of QoL and more disease complications. More and wider treatment and psychological care for improving quality of life of these patients are seriously recommended.

    Hashimoto's thyroiditis (HT) is the most common endocrine disorder leading to hypothyroidism. HT is characterized by the presence of elevated circulating antibodies, especially anti-thyroid peroxidase (anti-TPO) and anti-thyroglobulin (anti-Tg). In our study, we aimed to reveal the effects of autoimmunity on health-related quality of life of euthyroid HT patients. Patients who were admitted to the Adnan Menderes University Outpatient Clinic were enrolled. The medical records of the patients were surveyed and their demographical data were collected. By using communication data, the patients were invited to our clinic, to inform them about our study and to fill out the health-related quality of life questionnaire. A total of 84 euthyroid HT patients older than 18 years who completed the short form-36 questionnaire, were enrolled. As all patients were euthyroid, there was a significant negative correlation between each domain score and the antibody levels, individually. Patients who had higher anti-TPO and anti-Tg levels had significantly lower quality of life domain scores (p < 0.001). There was statistically no significant correlation between the antibody levels and thyroid function tests (p > 0.05). Additionally, all dimension scores were significantly higher both in the anti-Tg and anti-TPO negative groups, indicating a better quality of life than that in the antibody positive groups. Our study revealed that higher thyroid antibody levels were negatively correlated with life quality scores. Thus, patients who had higher anti-TPO and anti-Tg levels had significantly lower quality of life domain scores. We believe that apart from hypothyroidism, a high antibody level was one of the contributing factors for the development of HT-associated symptoms, leading to a lower quality of life. Other probable contributing factors such as selenium deficiency, thyroid hormone fluctuation, and disease awareness should keep in mind. PMID:27523457

    Background Patients with psychoses have an increased risk of becoming victims of violence. Previous studies have suggested that higher symptom levels are associated with a raised risk of becoming a victim of physical violence. There has been, however, no evidence on the type of symptoms that are linked with an increased risk of recent victimization. Methods Data was taken from two studies on involuntarily admitted patients, one national study in England and an international one in six other European countries. In the week following admission, trained interviewers asked patients whether they had been victims of physical violence in the year prior to admission, and assessed symptoms on the Brief Psychiatric Rating Scale (BPRS). Only patients with a diagnosis of schizophrenia or related disorders (ICD-10 F20–29) were included in the analysis which was conducted separately for the two samples. Symptom levels assessed on the BPRS subscales were tested as predictors of victimization. Univariable and multivariable logistic regression models were fitted to estimate adjusted odds ratios. Results Data from 383 patients in the English sample and 543 patients in the European sample was analysed. Rates of victimization were 37.8% and 28.0% respectively. In multivariable models, the BPRS manic subscale was significantly associated with victimization in both samples. Conclusions Higher levels of manic symptoms indicate a raised risk of being a victim of violence in involuntary patients with schizophrenia and related disorders. This might be explained by higher activity levels, impaired judgement or poorer self-control in patients with manic symptoms. Such symptoms should be specifically considered in risk assessments.

    The aim of this study was to explore the variability in hospital admissions of patients with spondyloarthritis (SpA) in Spain, and the centre factors that may influence that variability. Descriptive cross-sectional study, part of the emAR II study, performed in Spain (2009-2010). Health records of patients with a diagnosis of SpA and at least one visit to the rheumatology units within the previous 2 years were reviewed. Variables related to hospital admissions, to the SpA, and to the patient and centre were collected. A multilevel logistic regression analysis of random intercept with non-random slopes was performed to assess variability between centres. From 45 centres, 1168 patients' health records were reviewed. Main SpA forms were ankylosing spondylitis (55.2 %) and psoriatic arthritis (22.2 %). A total of 248 admissions were registered for 196 patients (19.2 %, n = 1020). An adjusted variability of 17.6 % in hospitalizations between centres was noted. The following hospital-related factors showed a significant association with admissions: the total number of admissions of the centre, the existence of electronic admission, and the availability of ultrasound in rheumatology. However, these factors only explained 42.9 % of the inter-centre variability. The risk of a patient with SpA of being admitted could double (median OR 2.09), depending on the hospital where the patient was being managed. Hospital admissions of patients with SpA varied between hospitals due to centre characteristics. Further studies are needed to ascertain which specific factors may be causing the variation, as studied variables explained less than half of the variability.

    Background Implantable cardioverter defibrillators (ICDs) are increasingly offered to patients for primary prevention of sudden cardiac death. Candidates for ICD receive ICD-related patient education material when they make decisions to consent or decline a primary prevention ICD. Printed patient education material directed at ICD candidates has not been the focus of direct appraisal. Objective We evaluated the readability and content of ICD-related print education materials made available to patients who were enrolled in a study involving patient decision making for ICD from 3 ICD sites in southern Ontario, Canada. Methods All ICD print materials referred to during interviews and/or that were available in ICD site waiting rooms were collected for analysis. Readability testing was conducted using the SMOG (“simple measurement of gobbledygook”) and Fry methods. The material was evaluated according to selected plain-language criteria, thematic content analysis, and rhetoric analysis. Results Twenty-one print materials were identified and analyzed. Documents were authored by device manufacturers, tertiary care hospitals, and cardiac support organizations. Although many documents adhered to plain-language recommendations, text-reading levels were higher than recommended. Twelve major content themes were identified. Content focused heavily on the positive aspects of living with the device to the exclusion of other possible information that could be relevant to the decisions that patients made. Conclusions Print-based patient education materials for ICD candidates are geared to a highly literate population. The focus on positive information to the exclusion of potentially negative aspects of the ICD, or alternatives to accepting 1, could influence and/or confuse patients about the purpose and implications of this medical device. Development of print materials is indicated that includes information about possible problems and that would be relevant for the

    We screened differential expression bone-related microRNAs (miRNAs) in serum of patients with osteogenesis imperfect (OI). First, we selected the reference gene (s) fit for quantitative detection of serum miRNAs by using geNorm and several other programmes. Then real-time fluorescent quntitative PCR was used to detect the expression level of bone-related miRNAs gained by means of miRanda, Targetscan and Pictar softwares caculation and reading literature. Then, the results were analyzed with the matched t test. All 6 candidate reference genes had a stable expression level in serum of healthy controls and patients with different characters, and the optimal number of reference genes is 4 (miR-16, let-7a, snRNAU6, miR-92a) after Pairwise Variations analysis (V4/5 = 0.133 < 0.15). For validating the universality of expression stability, we detected the relative expression value of miR-16, let-7a, snRNAU6 and miR-92a in another 8 healthy controls and 16 patients with OI and the result revealed that the expression of 4 genes remained stable (M < 1.5). After measuring serum levels of more than 100 bone-related miRNAs in patients with real-time qPCR, 11 miRNAs showed differential expression, and bioinformatic analysis suggested these altered expressional mioRNAs had possibilities to participate in the process of OI. So the experiment indicated that there existed many differential expression bone-related miRNAs in serum of patients with OI, and these miRNAs had potentials to be promising biomarkers for serologic tests and diagnosis of OI.

    Objective: The increasing number of available drugs and drug users, as well as more complex drug regimens led to more side effects and drug interactions and complicates follow-up. The objective of this study was to assess drug-related problems (DRPs) and associated factors in hospitalized patients. Methods: A hospital-based cross-sectional study design was employed. The study was conducted in Jimma University Specialized Hospital, Jimma, located in the south west of Addis Ababa. All patients who were admitted to the medical ward from February 2011 to March 2011 were included in the study. Data on sociodemographic variables, past medical history, drug history, current diagnosis, current medications, vital signs, and relevant laboratory data were collected using semi-structured questionnaire and data collection forms which were filling through patient interview and card review. Data were analyzed using SPSS version 16 for windows. Descriptive statistics, cross-tabs, Chi-square, and logistic regression were utilized. Findings: Out of 257 study participants, 189 (73.5%) had DRPs and a total of 316 DRPs were identified. From the six classes of DRPs studied, 103 (32.6%) cases related to untreated indication or need additional drug therapy, and 49 (15.5%) cases related to high medication dosage. Unnecessary drug therapy in 49 (15.5%) cases, low medication dosage in 44 (13.9%) cases, and ineffective drug therapy in 42 (13.3%) cases were the other classes of problems identified. Noncompliance in 31 (9.8%) cases was the least prevalent DRP. Independent factors which predicted the occurrence of DRPs in the study population were sex, age, polypharmacy, and clinically significant potential drug-drug interactions. The prevalence of DRPs was substantially high (73.5%). Conclusion: Drug-related problems are common among medical ward patients. Indication-related problems, untreated indication and unnecessary drug therapy were the most common types of DRPs among patients of our

    The aim of the study was to evaluate mental distress and health-related quality of life in patients with bilateral partial deafness (high-frequency sensorineural hearing loss) before cochlear implantation, with respect to their audiological performance and time of onset of the hearing impairment. Thirty-one patients and 31 normal-hearing individuals were administered the Beck Depression Inventory (BDI), the State-Trait-Anxiety-Inventory (STAI) and the World Health Organization Quality of Life-BREF questionnaire (WHOQOL-BREF). Patients also completed the Nijmegen-Cochlear-Implant-Questionnaire (NCIQ), a tool for evaluation of quality of life related to hearing loss. Patients revealed increased depressive and anxiety symptoms, as well as decreased health-related quality of life (psychological health, physical health), in comparison with their healthy counterparts (t tests, p < 0.05). Furthermore, a General Linear Model demonstrated in patients with a prelingual onset of hearing loss enhanced self-evaluated social interactions and activity (NCIQ), when their outcomes were contrasted with those obtained in individuals with postlingual partial deafness (p < 0.05). The study failed to show any effect of collateral tinnitus. Patients not using hearing aids had better audiological performance and, therefore, better sound perception and speech production, as measured with NCIQ. There was no effect of hearing aid use with respect to mental distress. Additional statistically significant correlations seen in patients included those between a steeper slope hearing loss configuration (averaged pure-tone thresholds at 1 and 2 kHz with subtracted threshold at 0.5 kHz) and better audiometric speech detection, between audiometric thresholds and the subjectively rated sound perception (NCIQ), as well as left-ear audiometric word recognition scores and the subjectively perceived ability to recognize advanced sounds (NCIQ). In addition, a longer duration of postlingual deafness, as

    In this paper, we study thermostatistical properties of a photon gas in the framework of two deformed special relativity models defined by the cosmological coordinatizations of the de Sitter (dS) and anti-de Sitter (AdS) momentum spaces. The dS model is a doubly special relativity theory in which an ultraviolet length scale is invariant under the deformed Lorentz transformations. For the case of the AdS model, however, the Lorentz symmetry breaks at the high energy regime. We show that the existence of a maximal momentum in dS momentum space leads to maximal pressure and temperature at the thermodynamical level, while maximal internal energy and entropy arise for the case of the AdS momentum space due to the existence of a maximal kinematical energy. These results show that the thermodynamical duality of these models is very similar to their well-known kinematical duality.

    Background Health-related quality of life (HRQOL) reflects the general well-being of individuals. In patients with coronary artery disease (CAD), HRQOL is compromised. Female patients with CAD have been reported to have lower HRQOL. In this study, we investigate gender differences in HRQOL and in associations of patient characteristics with HRQOL in patients with coronary angiography (CAG). Methods We cross-sectionally analysed patients from the Utrecht Coronary Biobank undergoing CAG. All patients filled in an HRQOL questionnaire (RAND-36 and EuroQoL) on inclusion. RAND-36 and EuroQoL HRQOL measures were compared between the genders across indications for CAG, CAD severity and treatment of CAD. RAND-36 HRQOL measures were compared with the general Dutch population. Additionally, we assessed interactions of gender with patient characteristics in their association with HRQOL (EuroQoL). Results We included 1421 patients (1020 men and 401 women) with a mean age of 65 in our analysis. Women reported lower HRQOL measures than men (mean EuroQoL self-rated health grade 6.84±1.49 in men, 6.46±1.40 in women, p<0.001). The reduction in RAND-36 HRQOL as compared with the general Dutch population was larger in women than in men. From regression analysis, we found that diabetes, a history of cardiovascular disease and symptoms of shortness of breath determined HRQOL (EuroQoL) more strongly in men than in women. Conclusions Women reported lower HRQOL than men throughout all indications for CAG and regardless of CAD severity or treatment. As compared with the general population, the reduction in HRQOL was more extreme in women than in men. Evident gender differences were found in determinants of HRQOL in patients undergoing CAG, which deserve attention in future research. Trial registration NCT02304744 (clinicaltrials.gov).

    In English, transitive events can be described in various ways. The main possibilities are active-voice and passive-voice, which are assumed to have distinct semantic and pragmatic functions. Within the passive, there are two further options, namely be-passive or get-passive. While these two forms are generally understood to differ, there is little agreement on precisely how and why. The passive Patient is frequently cited as playing a role, though again agreement on the specifics is rare. Here we present three paraphrasing experiments investigating Patient-related constraints on the selection of active vs. passive voice, and be- vs. get-passive, respectively. Participants either had to re-tell short stories in their own words (Experiments 1 and 2) or had to answer specific questions about the Patient in those short stories (Experiment 3). We found that a given Agent in a story promotes the use of active-voice, while a given Patient promotes be-passives specifically. Meanwhile, get-passive use increases when the Patient is marked as important. We argue that the three forms of transitive description are functionally and semantically distinct, and can be arranged along two dimensions: Patient Prominence and Patient Importance. We claim that active-voice has a near-complementary relationship with the be-passive, driven by which protagonist is given. Since both get and be are passive, they share the features of a Patient-subject and an optional Agent by-phrase; however, get specifically responds to a Patient being marked as important. Each of these descriptions has its own set of features that differentiate it from the others. PMID:24273527

    The diagnostic related group (DRG) prospective hospital payment system has been on line for five years with no major changes implemented by the federal government. Data suggest that the DRG system may be inequitable to patients of lower socioeconomic status. We studied the consumption of hospital resources by race (ie, white vs black) for hospitalized medical patients using the DRG prospective payment system. All adult medical admissions (N = 30,097) were analyzed for a three-year period at a large academic medical center using the DRG "all payor" classification scheme in effect for New York State. We found that black patients (N = 3,373) had a significantly greater (P less than .0001) mean length of hospital stay and cost per patient (adjusted for DRG weight index) compared with white patients (N = 26,724). Black patients also exposed the medical center to greater (P less than .0001) financial risk compared with white patients, as measured by outliers and losses under DRGs. Black patients (P less than .0001) had a significantly higher proportion of emergency admissions to the hospital, a greater severity of illness (as measured by total International Classification of Diseases-9-Clinical Modification codes) (P less than .0001), and higher diagnostic costs (P less than .0001) for each episode of illness. These data suggest that at our medical center black medical patients may consume more hospital resources (adjusted for DRG case mix) compared with whites. It is important that methods to modify DRG prospective hospital payment for medical diseases be considered to provide more equitable DRG reimbursement for black Americans in the future.

    Chronic kidney disease (CKD) is a worldwide public health problem, and its treatment imposes a considerable burden on patients and their families. Limitations in everyday activity may worsen the situation and affect the health-related quality of life (HRQOL) of patients with CKD. There are no studies on the HRQOL of dialysis patients in South Africa. We assessed the HRQOL of patients undergoing hemodialysis (HD) and continuous ambulatory peritoneal dialysis (PD) attending the Groote Schuur Hospital renal unit by using the Kidney Disease Quality of Life-Short Form version 1.3 questionnaire. Baseline demographic and clinical details of the participants were recorded. Analysis was performed (unpaired t test and univariate analysis) to compare the HRQOL between HD and PD patients and to identify factors influencing HRQOL. The HRQOL was low but not significantly different between HD and PD patients. In PD patients, the use of erythropoiesis-stimulating agents (ESA) significantly contributed to the emotional well-being (r 2 = 0.267; P = 0.01) and alleviation of pain (r 2 = 0.073; P = 0.049); in HD patients also, ESA use was associated with emotional well-being (r 2 = 0.258; P <0.0001) as well as improvement in energy/fatigue (r 2 = 0.390; P <0.0001). Systolic and diastolic blood pressures significantly influenced cognitive function in PD patients (P <0.05). Parathyroid hormone level significantly influenced the physical functioning and energy/fatigue domains in HD patients (P <0.0001). Serum ferritin (r 2 = 0.441; P = 0.002) and level of hemoglobin concentration (r 2 = 0.180; P = 0.006) were significantly associated with the domain role emotional in PD and HD patients, respectively. Although HRQOL is low in dialysis patients in Cape Town, the factors that have been identified to be associated with these scores (such as anemia and hyperparathyroidism) if aggressively managed and corrected may assist in improving patients' HRQOL.

    One hundred and twenty patients with symptomatic rheumatoid arthritis (RA) or osteoarthritis (OA) in weight bearing joints (RA = 40; OA = 80) performed subjective maximal graded exercise tests on a motor driven treadmill. Disease related measures were also assessed. Findings from this sample indicated that people with arthritis were significantly impaired in exercise tolerance, flexibility and biomechanical efficiency. Significant differences between diagnoses appeared on a number of disease related measures; however, there was little correlation between disease related measures and exercise tolerance. Women demonstrated a greater aerobic impairment than men; and women with RA had a greater aerobic deficit than women with OA.

    Atrial fibrillation is the most common sustained cardiac arrhythmia affecting 1-2% of the population; the prevalence of atrial fibrillation increases with ageing. The condition is associated with high morbidity and mortality, as well as reduced health-related quality of life, particularly in older people. A PubMed, CINAHL, EMBASE and CENTRAL search (January 2003 to April 2013) was conducted using the search terms atrial fibrillation, quality of life, health-related quality of life, older, aged, and over 65 years. In total, 572 papers were identified of which 15 were eligible, including three observational studies, five descriptive comparative studies and seven randomized control trials. Older atrial fibrillation patients (≥65 years) were significantly impaired in their health-related quality of life in both physical and mental domains compared to the general population or patients with sinus rhythm. Increasing age, being female or having severe symptoms resulted in poorer health-related quality of life particularly in the physical domain. The review also found that the current treatment of AF including rate and rhythm control strategies improved some aspects of health-related quality of life in atrial fibrillation patients but no specific strategy had a superior effect.

    Background and Aim Metabolic syndrome (MetS), albuminuria, and the Framingham Risk Score (FRS) are significant predictors for cardiovascular disease (CVD). However, the relationship and clinical significance of these CVD predictors in individuals with a family history of end-stage renal disease (ESRD) are unclear. We investigated the association of relatives of hemodialysis (HD) patients with MetS, albuminuria, and the FRS. Methods One hundred and sixty-six relatives of HD patients and 374 age- and sex- matched community controls were enrolled. MetS was defined using the Adult Treatment Panel III for Asians. Albuminuria was defined as urine albumin-to-creatinine ratio ≥30 mg/g. CVD risk was evaluated by the FRS. Results A significantly higher prevalence of MetS (19.9% vs. 12.5%, P = 0.026), albuminuria (12.7% vs. 5.1%, P = 0.002) and high FRS risk ≥10% of 10-year risk (15.7% vs. 8.5%, P = 0.013) was found in relatives of HD patients compared to their counterpart controls. In multivariate analysis, being relatives of HD patients (vs. controls) was an independent determinant for MetS (odds ratio [OR], 1.785; 95% confidence interval [CI], 1.045 to 3.050), albuminuria (OR, 2.891; 95% CI, 1.431 to 5.841), and high FRS risk (OR, 1.863; 95% CI, 1.015 to 3.418). Higher low-density lipoprotein cholesterol (OR, 1.034; 95% CI, 1.017 to 1.052) and betel nut chewing (OR, 13.994; 95% CI, 3.384 to 57.871) were independent determinants for having a high FRS risk in relatives of HD patients. Conclusions Being relatives of HD patients was independently associated with MetS, albuminuria and high FRS risk, suggesting family members of ESRD patients may have higher CVD risks through the interactions of renal risk factors. Proactive surveillance of these CVD predictors and preventive strategies should be targeted to this high-risk population. PMID:24804770

    High expressed emotion (high EE) in family members (high levels of criticism, emotional overinvolvement, and/or hostility) has been found to be predictive of a poorer course of illness for patients with schizophrenia in many different cultures. Acculturation has also been found to relate to symptom severity and clinical course in a number of disorders (e.g., substance abuse, schizophrenia). There is reason to believe that acculturation may interact with EE, however, this relationship has yet to be examined systematically. The present study evaluated the relationship between acculturation and EE in a sample of 57 Caucasian, Latino, and black caregivers of patients with schizophrenia. Drawing from earlier research, it was hypothesized that more acculturated Caucasian and Latino relatives and less acculturated black relatives would be designated as high EE. Hypotheses were partially supported as results demonstrated that greater acculturation was associated with high EE for Latinos and low EE for blacks. PMID:18000456

    Autism is a neurodevelopmental disorder with indisputable evidence for a genetic component. This work studied the association of autism with genetic variations in neurotransmitter-related genes, including MAOA uVNTR, MAOB rs1799836, and DRD2 TaqI A in 53 autistic patients and 30 healthy individuals. The study also analyzed sequence variations of miR-431 and miR-21. MAOA uVNTR was genotyped by PCR, MAOB and DRD2 polymorphisms were analyzed by PCR-based RFLP, and miR-431 and miR-21 were sequenced. Low expressing allele of MAOA uVNTR was frequently higher in female patients compared to that in controls (OR = 2.25). MAOB G allele frequency was more significantly increased in autistic patients than in controls (P < 0.001 for both males and females). DRD2 A1+ genotype increased autism risk (OR = 5.1). Severity of autism tends to be slightly affected by MAOA/B genotype. Plasma MAOB activity was significantly reduced in G than in A allele carrying males. There was no significant difference in patients and maternal plasma MAOA/B activity compared to controls. Neither mutations nor SNPs in miR-431 and miR-21 were found among studied patients. This study threw light on some neurotransmitter-related genes suggesting their potential role in Autism pathogenesis that warrants further studies and much consideration. PMID:24453887

    We studied healthy, first-degree relatives of patients with schizophrenia to test the hypothesis that deficits in cognitive skill learning are associated with genetic liability to schizophrenia. Using the Weather Prediction Task (WPT), 23 healthy controls and 10 adult first-degree Relatives Of Schizophrenia (ROS) patients were examined to determine the extent to which cognitive skill learning was automated using a dual-task paradigm to detect subtle impairments in skill learning. Automatization of a skill is the ability to execute a task without the demand for executive control and effortful behavior and is a skill in which schizophrenia patients possess a deficit. ROS patients did not differ from healthy controls in accuracy or reaction time on the WPT either during early or late training on the single-task trials. In contrast, the healthy control and ROS groups were differentially affected during the dual-task trials. Our results demonstrate that the ROS group did not automate the task as well as controls and continued to rely on controlled processing even after extensive practice. This suggests that adult ROS patients may engage in compensatory strategies to achieve normal levels of performance and support the hypothesis that impaired cognitive skill learning is associated with genetic risk for schizophrenia.

    Foot ulcers are a common, serious, and costly complication of diabetes, preceding 84% of lower extremity amputations in diabetic patients and increasing the risk of death by 2.4-fold over diabetic patients without ulcers. Health-related quality of life (HRQOL) is worse among individuals with diabetes than individuals without diabetes, and complications of diabetes, including foot ulcers, have a major negative effect on HRQOL. Diabetic foot ulcers are associated with reduced mobility and deficits related to activities of daily living that adversely affect HRQOL. Qualitative studies have confirmed clinical observations that diabetic foot ulcers have a huge negative psychological and social effect, including reduction in social activities, increased family tensions for patients and their caregivers (spouses or partners), limited employment, and financial hardship. Quantitative studies confirm the findings of qualitative studies that diabetic foot ulcers exert a negative effect on physical functioning, psychological status, and social situation. Recent advances include the development and validation of disease-specific HRQOL surveys for diabetic patients with foot ulcers. Disease-specific surveys may improve the evaluation of HRQOL as a function of ulcer healing, the effect of different treatment methods on HRQOL, and the relationship between treatment-specific HRQOL, patient compliance, and treatment efficacy.

    Background: The cytotoxic T lymphocyteassociated antigen 4 gene (CTLA-4) encode the T cell receptor involved in the control of T cell proliferation and mediates T cell apoptosis. The receptor protein is a specific T lymphocyte surface antigen that is detected on cells only after antigen presentation. Thus, CTLA-4 is directly involved in both immune and autoimmune responses and may be involved in the pathogenesis of multiple T cell-mediated autoimmune disorders. There is polymorphism at position 49 in exon 1 of the CTLA-4 gene, providing an A-G exchange. Moreover, we assessed the CTLA-4 49 (Thr/Ala) polymorphism in diabetic patients and first-degree relatives as compared to control subjects. Research design and methods: Three loci (HLA-DQB1, DQA1 and CTLA-4) were analysed in 62 type 1 diabetic patients, 72 firstdegree relatives and 84 nondiabetic control subjects by means of PCR-RFLP. Results: A significant enrichment in DQB1 alleles encoding for an amino acid different from Asp in position 57 (NA) and DQA1 alleles encoding for Arg in position 52 was observed in diabetic subjects and first-degree relatives as compared to controls. The genotype and allele frequencies of these polymorphisms in type 1 diabetic patients and firstdegree relatives differed significantly from those of controls (p< 0.001 and 0.05 respectively). CTLA-49 Ala alleles frequencies were 75.8% in type 1 diabetic patients and 68.1% in first-degree relatives in comparison to 35.7% in control subjects. The Ala/Ala genotype conferred a relative risk of 18.8 (p < 0.001). Conclusion: The CTLA-4 49 Ala allele confers an increased risk of type 1 diabetes, independent of age and HLA-DQ genetic markers.

    The impact of human immunodeficiency virus (HIV) coinfection on the survival of patients with hepatitis C virus (HCV)-related end-stage liver disease (ESLD) is unknown. Because HIV infection is no longer considered an absolute contraindication for liver transplantation in some countries, it has become a priority to address this topic. The objective of this study was to compare the survival of HIV-infected and HIV-uninfected patients with decompensated cirrhosis due to HCV. In a retrospective cohort study, the survival of 1,037 HCV monoinfected and 180 HCV/HIV-coinfected patients with cirrhosis after the first hepatic decompensation was analyzed. Of the group, 386 (37%) HCV-monoinfected and 100 (56%) HCV/HIV-coinfected subjects died during the follow-up. The median survival time of HIV-infected and HIV-uninfected patients was 16 and 48 months, respectively (P < .001). The relative risk (95% CI) of death for HIV-infected patients was 2.26 (1.51-3.38). Other independent predictors of survival were age older than 63 years (2.25 [1.53-3.31]); Child-Turcotte-Pugh class B versus class A (1.95 [1.41-2.68]) and class C versus class A (2.78 [1.66-4.70]); hepatitis D virus infection (1.56 [1.12-4.77]); model for end-stage liver disease score, (1.05 [1.01-1-11]); more than one simultaneous decompensation (1.23 [1.12-3.33]); and the type of the first hepatic decompensation, with a poorer prognosis associated with encephalopathy compared with portal hypertensive gastrointestinal bleeding (2.03 [1.26-3.10]). In conclusion, HIV coinfection reduces considerably the survival of patients with HCV-related ESLD independently of other markers of poor prognosis. This fact must be taken into account to establish the adequate timing of liver transplantation in HIV-coinfected subjects.

    Background Hypertension control is a challenge globally. Barriers to optimal control exist at the patient, physician, and health system levels. Patient-related barriers in our environment are not clear. The aim of this study was to identify patient-related barriers to control of hypertension among adults with hypertension in a semiurban community in South-East Nigeria. Methods This was a cross-sectional descriptive study of patients with a diagnosis of hypertension and on antihypertensive medication. Results A total of 252 participants were included in the survey, and comprised 143 males (56.7%) and 109 females (43.3%). The mean age of the participants was 56.6±12.7 years, with a diagnosis of hypertension for a mean duration of 6.1±3.3 years. Among these patients, 32.9% had controlled blood pressure, while 39.3% and 27.8%, respectively, had stage 1 and stage 2 hypertension according to the Seventh Report of the Joint National Committee on Prevention, Detection and Evaluation of High Blood Pressure. Only 23.4% knew the consequences of poor blood pressure control and 64% were expecting a cure from treatment even when the cause of hypertension was not known. Furthermore, 68.7% showed low adherence to medication, the reported reasons for which included forgetfulness (61.2%), financial constraints (56.6%), high pill burden (22.5%), side effects of medication (17.3%), and low measured blood pressure (12.1%). Finally, knowledge and practice of the lifestyle modifications necessary for blood pressure control was inadequate among the participants. Conclusion Poor knowledge regarding hypertension, unrealistic expectations of treatment, poor adherence with medication, unawareness of lifestyle modification, and failure to apply these were identified as patient-related barriers to blood pressure control in this study.

    This study was necessitated by the international recognition of wound-related pain (WRP) as a must-address issue and patient-centred concerns. The aim of this study was to assess patients' WRP experiences at rest and in relation to dressing change. This descriptive study utilised a WRP questionnaire which incorporated a visual analogue scale of 0-10 for data collection. A total of 109 patients participated in this study; 95·4% of the participants experienced wound pain at rest and during performance of activities of daily living, which were moderate (47·1%) and severe (30·8%) in intensity. Also, 91·7% of the participants experienced wound dressing change-related pain, mostly as moderate (47·0%) and severe (28·0%) pain. The major factors that worsened WRP experiences were touch/handling, change in position/movement, wound cleansing, removal of dressings and usage of honey as a dressing agent, while the use of analgesic and brief rest between dressing change were considered the major strategies that can relieve WRP. WRP experiences have been reported by patients at rest, during performance of activities of daily living and at wound dressing change. A need to incorporate WRP assessment has been observed, which is vital in improving wound care outcome.

    Background There is increased interest in the study of cognitive deficits as possible endophenotypic markers for schizophrenia. The main goal of this study was to determine how familiality and schizophrenia spectrum personality symptomatology are related to performance of auditory and visuospatial delayed recognition memory tasks. Methods The study sample consisted of 162 subjects divided into five groups. The groups included 39 patients with a DSM-IV diagnosis of schizophrenia or schizophreniform disorder, first-degree relatives of schizophrenia patients, 22 with and 31 without schizophrenia spectrum personality traits, and healthy controls with no family history of psychosis, 22 with and 48 without schizophrenia spectrum traits. Auditory and visuospatial delayed recognition memory performance was assessed. Results Significant differences were observed between patients and healthy controls in both auditory [F1,79=7.358 p=.008] and visual [F1,47=34.67, p<.001] delayed recognition tasks. When comparing the four non-patient groups, auditory and visuospatial discriminability decreased as a function of familiality of schizophrenia (p<0.05). Deficits were more pronounced in relatives with schizophrenia spectrum traits [auditory d=0.7114; visual d = .0199]. Conclusions A biological relationship to schizophrenia increases the likelihood of impaired delayed recognition memory. Likewise, poorer performance is associated with schizophrenia spectrum phenotype only when combined with familiality. PMID:17916332

    The key role of an intact gastric acid secretion for subsequent intestinal T4 absorption is supported by an increased requirement of thyroxine in patients with gastric disorders. A better pH-related dissolution profile has been described in vitro for softgel T4 preparation than for T4 tablets. Our study was aimed at comparing softgel and tablet T4 requirements in patients with gastric disorders. A total of 37 patients with gastric-related T4 malabsorption were enrolled, but only 31 (28F/3M; median age = 50 years; median T4 dose = 2.04 μg/kg/day) completed the study. All patients were in long-lasting treatment (>2 years) with the same dose of T4 tablets when treatment was switched to a lower dose of softgel T4 capsules (-17 %; p = 0.0002). Assessment of serum FT4 and TSH was carried out at baseline and after 3, 6, 12, and 18 months after the treatment switch. In more than 2/3 of patients (good-responders n = 21), despite the reduced dose of T4, median TSH values were similar at each time point (p = 0.3934) with no change in FT4 levels. In the remaining patients (poor-responders n = 10), TSH levels were significantly higher at each time point than at baseline (p < 0.0001). To note, in five of them intestinal comorbidity was subsequently detected. Comorbidity associated with poor-responders status was the only significant predictor in multivariate analysis (OR = 11.333). Doses of softgel T4 capsules lower than T4 tablet preparation are required to maintain the therapeutic goal in 2/3 of patients with impaired gastric acid secretion.

    Dentists often treat patients who may be suffering from comorbid mental disorders without paying attention to their symptoms. This leads to a delay in starting the treatment of mental disorders and to inappropriate dental treatments for physical symptoms originating from mental disorders. In the present study, the ways in which dentists can easily detect mental disorders in dental patients with occlusion-related problems were examined. Fifty-three patients who visited the Occlusion Clinic of Kanagawa Dental College were interviewed by a psychiatrist and a dentist specialized in psychosomatic medicine. Thirty-five patients (66.0%) were diagnosed as having DSM-IV Axis I disorders. The demographic and psychological factors that correlate with the presence of mental disorders are duration of chief complaint, number of clinics and hospitals visited for the current symptom, total score of the General Health Questionnaire (GHQ), the scores of the anxiety and insomnia and social dysfunction subscales in the GHQ and the scores of the confusion-bewilderment and fatigue-inertia subscales in the Profile of Mood States (POMS). A logistic regression analysis indicated that number of clinics and hospitals visited markedly correlated with cormobidity of a mental disorder. This information may be useful for screening mental disorder patients. Dental patients having comorbid mental disorders should be treated both odontologically and psychologically. PMID:17472601

    Guillain-Barré syndrome (GBS) encompasses a broad spectrum of health-related quality of life (HRQL) determinants, including mobility, fatigue, pain, and depression. We systematically reviewed the literature on functional outcome domains in which GBS patients experience limitations in the short and long terms and evaluated determinants of HRQL in GBS patients. MEDLINE and EMBASE were systematically searched by two independent reviewers for articles covering HRQL data of GBS patients. Of 730 abstracts screened, 17 articles covering data of 14 studies matched the selection criteria. The included articles showed that many GBS patients experienced physical limitations, even years after the acute phase of the disease, while results were inconsistent for perceived levels of pain, fatigue, and general mental well-being. Only three papers covered HRQL assessments at more than one time point, generally showing large improvements in HRQL in the first year after GBS onset, but not thereafter. We appraised the methodological quality of included studies using a 13-item checklist; none of the articles fulfilled all items and only seven articles presented data on correlations between HRQL and determinants. In conclusion, the majority of studies on HRQL in GBS patients are cross-sectional and of low methodological quality. This paper provides guidance for much needed high-quality studies on patterns of patient-perceived recovery after GBS onset.

  8. Doctor-patient relations in dermatology: obligations and rights for a mutual satisfaction.

    2009-11-01

    The author examines different aspects of patient-doctor relationship in dermatological consultations. At first, a definition of patients satisfaction is given, based on available literature. It has been shown that satisfaction depends on diagnosis, but also on the doctor's ability to provide explanations on the probable cause of the illness, information on how long the symptom will probably last, and if she/he demonstrates empathy. Satisfaction also increases if the illness is serious, but decreases if quality of life linked to the symptom is underestimated by the doctor. After providing a philosophical definition of ethics, which emphasizes the importance of mutual satisfaction of patient and doctor, the concepts of empathy and compassion in patient-doctor relations are defined. Their importance in consultations is underlined, reporting, for example, that doctors with good communication skills experience fewer difficult consultations (8% vs. 23%). Afterwards, the dermatological consultation is analysed in its practical aspects, trying to define a good-quality consultation. First of all, the pitfalls that can affect good time management are analysed, suggesting to structure the consultation using the Soap method. Particular situations are analysed, such as announcing bad news and dealing with borderline patients. Finally, the concept of transference is defined, remembering that doctor-patient relationships can replay some difficult relationship coming from the past, and thus doctors need to be aware of this possibility and learn how to manage it.

    The goal of this research was to evaluate the personal health behaviors of physicians in training and attending physicians in association with patient-related lifestyle counseling. Physicians at a major teaching hospital were surveyed regarding their personal lifestyle behavior, perceived confidence, and frequency of counseling patients regarding lifestyle behaviors. One hundred eighty-three total responses were received. Trainees were more likely to consume fast food and less likely to consume fruits and vegetables than attendings. Attending physicians were more likely to exercise 4 or more days per week and more than 150 minutes per week. Attending physicians were more likely to counsel their patients regarding a healthy diet (70.7% vs 36.3%, P<.0001) and regular exercise (69.1% vs 38.2%, P<.0001) compared with trainees. Few trainees or attendings were confident in their ability to change patients' behaviors. Predictors of confidence in counseling for exercise included the provider's own exercise time of > 150 minutes per week, being overweight, and reported adequate training in counseling. Only adequate training in counseling was a predictor of strong self-efficacy for counseling in diet. Many physicians lack confidence in their ability to counsel patients regarding lifestyle. Personal behaviors including regular exercise and better training in counseling techniques may improve patient counseling.

    Problems in daily life activities caused by bad vision were studied in 150 patients with cataract before and 6 months after a cataract extraction. A relation was found between binocular visual acuity before surgery and the number of problems experienced (p < 0.001). After cataract extraction a reduction in problems was closely associated with an increase in visual acuity (p < 0.001) and also, in the patients' opinion, a better life situation (p < 0.001). Six questions to be answered when considering surgery are given. PMID:7918286

    The most common apolipoprotein E (APOE) allelic variation is implicated in many age-related diseases and human longevity with controversial findings. We investigated the effect of APOE gene polymorphism on all-cause mortality in elderly patients taking into consideration the functional disability, cognitive impairment, malnutrition, and the occurrence of common age-related diseases. APOE genotypes were determined in 2,124 geriatric hospitalized patients (46.5% men and 53.5% women; mean age, 78.2 +/- 7.1 years; range, 65-100 years). At hospital admission, all patients underwent a comprehensive geriatric assessment to evaluate functional disability, cognitive status, nutritional status, and comorbidity. The main and secondary diagnoses at hospital discharge were also recorded. Mortality status was evaluated in all patients after a maximum follow-up of 5 years (range, from 1.26 to 5.23 years; median, 2.86 years). During the study period, 671 patients died (32.0%). At hospital admission, these patients showed a significant higher prevalence of cardiovascular diseases (56.3% vs 53.4%; p = 0.007), neoplasias (32.3% vs 13.7%; p < 0.001), and lower prevalence of neurodegenerative diseases (17.7% vs 20.7%; p < 0.001) than survived patients. Moreover, they also showed an higher prevalence of disability (52.0% vs 25.6%; p < 0.001), cognitive impairment (31.0% vs 18.8%; p < 0.001), and malnutrition (74.0% vs 46.1%; p < 0.001) than survived patients. In the overall study population, the APOE epsilon2 allele was significantly associated to neurodegenerative diseases (odds ratio = 0.59; 95% confidence interval (CI), 0.37-0.94). No significant association between the APOE polymorphism and disability, malnutrition, co-morbidity status, and with all-cause mortality was observed. In patients with cardiovascular diseases, however, a decreased risk of all-cause mortality was found in the epsilon2 allele carriers (hazard ratio = 0.56; 95% CI, 0.36-0.88). In this population, APOE allele

    2012-01-01

    Background An influence of gonadotropins (hCG) on the development of ovarian cancer has been discussed. Therefore, we quantified serum hCG levels in patients with benign and malignant ovarian tumors and the hCG expression in ovarian cancer tissue in order to analyze its relation to grade, stage, gonadotropin receptor (LH-R, FSH-R) expression and survival in ovarian cancer patients. Methods Patients diagnosed and treated for ovarian tumors from 1990 to 2002 were included. Patient characteristics, histology including histological subtype, tumor stage, grading and follow-up data were available. Serum hCG concentration measurement was performed with ELISA technology, hCG tissue expression determined by immunohistochemistry. Results HCG-positive sera were found in 26.7% of patients with benign and 67% of patients with malignant ovarian tumors. In addition, significantly higher hCG serum concentrations were observed in patients with malignant compared to benign ovarian tumors (p = 0.000). Ovarian cancer tissue was positive for hCG expression in 68%. We identified significant differences in hCG tissue expression related to tumor grade (p = 0.022) but no differences with regard to the histological subtype. In addition, mucinous ovarian carcinomas showed a significantly increased hCG expression at FIGO stage III compared to stage I (p = 0.018). We also found a positive correlation of hCG expression to LH-R expression, but not to FSH-R expression. There was no significant correlation between tissue hCG expression and overall ovarian cancer patient survival, but subgroup analysis revealed an increased 5-year survival in LH-R positive/FSH-R negative and hCG positive tumors (hCG positive 75.0% vs. hCG negative 50.5%). Conclusions Serum human gonadotropin levels differ in patients with benign and malignant ovarian tumors. HCG is often expressed in ovarian cancer tissue with a certain variable relation to grade and stage. HCG expression correlates with LH-R expression in ovarian

    A work-related orientation within medical rehabilitation represents concepts with a stronger focus on the patient's individual vocational requirements and is based on different vocationally-orientated strategies of treatment. "Medical Occupational Orientation" ("Medizinisch-berufliche Orientierung", MBO), the model of Klinik Niedersachsen in Bad Nenndorf, places Functional Capacity Evaluation according to Susan Isernhagen (EFL) at the centre of rehabilitation diagnostics and therapy. This study investigates the effects of the MBO model relative to activities and vocational participation of patients with musculoskeletal disorders faced with vocational problems and on management at the interface between medical and vocational rehabilitation. Presented are findings of a randomized follow-up study aimed at evaluating the MBO model. A total of 494 patients of LVA Westfalen, a regional insurance agency, took part. A need for MBO was diagnosed for 222 patients. These patients were randomly assigned either to the MBO model of treatment (experimental group --> U[+]) or to the conventional medical treatment (control group --> K[+]). Patients without a need for MBO (U[-], K[-]) were treated likewise. The written questionings took place at the beginning (t (1)) and end of rehabilitation (t (2)), as well as six (t (3)) and twelve months (t (4)) after the patients' discharge. Currently, the results are based on the 6-month follow-up. Concerning the activities, an MBO-related effect in the experimental group (U[+]) has been found for the Pain Disability Index (PDI), effect sizes being d (u+) = 0.82; d (k+) = 0.17. The risk of unemployment six months after rehabilitation is decreased for MBO(+) patients who participated in the MBO model. In addition, the clinic can make effective prognosis concerning subsequent participation in vocational rehabilitation for both experimental groups (U[+], U[-]). Established for the first time in a randomized controlled trial, the findings

    This review considers the possible familial relationship of schizotypal and paranoid personality disorders (SPD, PPD) to schizophrenia (SCZ) and affective disorders (AD). There have been few controlled studies on familial risk of SPD and PPD based on direct semi-structured interviews of relatives, blind to proband diagnosis. Three of six studies reported increased familial risk of SPD for SCZ probands, but with considerable variability in estimates of this risk. None of four studies reported a significant relationship between AD and familial SPD. There is substantial but less consistent evidence for a familial relationship between PPD and SCZ: three of six studies supported such a relationship, but one large study reported increased familial risk of PPD for AD and not for SCZ probands. There is also some evidence that negative symptoms are most characteristic of SPD in relatives of SCZ probands. Also discussed are issues concerning the adequacy of current criteria for defining schizophrenia spectrum pathology, and of diagnostic methods in this area.

    Background Understanding the perception of patients on research ethics issues related to biobanking is important to enrich ethical discourse and help inform policy. Methods We examined the views of leukemia patients undergoing treatment in clinics located in the Princess Margaret Hospital in Toronto, Ontario, Canada. An initial written survey was provided to 100 patients (64.1% response rate) followed by a follow-up survey (62.5% response rate) covering the topics of informed consent, withdrawal, anonymity, incidental findings and the return of results, ownership, and trust. Results The majority (59.6%) preferred one-time consent, 30.3% desired a tiered consent approach that provides multiple options, and 10.1% preferred re-consent for future research. When asked different questions on re-consent, most (58%) reported that re-consent was a waste of time and money, but 51.7% indicated they would feel respected and involved if asked to re-consent. The majority of patients (62.2%) stated they had a right to withdraw their consent, but many changed their mind in the follow-up survey explaining that they should not have the right to withdraw consent. Nearly all of the patients (98%) desired being informed of incidental health findings and explained that the information was useful. Of these, 67.3% of patients preferred that researchers inform them and their doctors of the results. The majority of patients (62.2%) stated that the research institution owns the samples whereas 19.4% stated that the participants owned their samples. Patients had a great deal of trust in doctors, hospitals and government-funded university researchers, moderate levels of trust for provincial governments and industry-funded university researchers, and low levels of trust towards industry and insurance companies. Conclusions Many cancer patients surveyed preferred a one-time consent although others desired some form of control. The majority of participants wanted a continuing right to withdraw

    Positioning patients for spine surgery is pivotal for optimal operating conditions and operative-site exposure. During spine surgery, patients are placed in positions that are not physiologic and may lead to complications. Perioperative peripheral nerve injury (PPNI) and postoperative visual loss (POVL) are rare complications related to patient positioning during spine surgery that result in significant patient disability and functional loss. PPNI is usually due to stretch or compression of the peripheral nerve. PPNI may present as a brachial plexus injury or as an isolated injury of single nerve, most commonly the ulnar nerve. Understanding the etiology, mechanism and pattern of injury with each type of nerve injury is important for the prevention of PPNI. Intraoperative neuromonitoring has been used to detect peripheral nerve conduction abnormalities indicating peripheral nerve stress under general anesthesia and to guide modification of the upper extremity position to prevent PPNI. POVL usually results in permanent visual loss. Most cases are associated with prolonged spine procedures in the prone position under general anesthesia. The most common causes of POVL after spine surgery are ischemic optic neuropathy and central retinal artery occlusion. Posterior ischemic optic neuropathy is the most common cause of POVL after spine surgery. It is important for spine surgeons to be aware of POVL and to participate in safe, collaborative perioperative care of spine patients. Proper education of perioperative staff, combined with clear communication and collaboration while positioning patients in the operating room is the best and safest approach. The prevention of uncommon complications of spine surgery depends primarily on identifying high-risk patients, proper positioning and optimal intraoperative management of physiological parameters. Modification of risk factors extrinsic to the patient may help reduce the incidence of PPNI and POVL. PMID:25232519

    Medication errors are one of the important factors that increase fatal injuries to the patients and burden significant economic costs to the health care. An appropriate medical history could reduce errors related to omission of the previous drugs at the time of hospitalization. The aim of this study, as first one in Iran, was evaluating the discrepancies between medication histories obtained by pharmacists and physicians/nurses and first order of physician. From September 2012 until March 2013, patients admitted to the post CCU of a 550 bed university hospital, were recruited in the study. As a part of medication reconciliation on admission, the physicians/nurses obtained medication history from all admitted patients. For patients included in the study, medication history was obtained by both physician/nurse and a pharmacy student (after training by a faculty clinical pharmacist) during the first 24 h of admission. 250 patients met inclusion criteria. The mean age of patients was 61.19 ± 14.41 years. Comparing pharmacy student drug history with medication lists obtained by nurses/physicians revealed 3036 discrepancies. On average, 12.14 discrepancies, ranged from 0 to 68, were identified per patient. Only in 20 patients (8%) there was 100 % agreement among medication lists obtained by pharmacist and physician/nurse. Comparing the medications by list of drugs ordered by physician at first visit showed 12.1 discrepancies on average ranging 0 to 72. According to the results, omission errors in our setting are higher than other countries. Pharmacy-based medication reconciliation could be recommended to decrease this type of error. PMID:27642331
