When physicians get stuck in sick-listing consultations: a qualitative study of categories of sick-listing dilemmas.

OBJECTIVE Many physicians find sick-listing tasks problematic. The aim of this study was to identify categories of dilemmas experienced by physicians in their sick-listing practice. DESIGN AND SUBJECTS Data was collected at courses that were aimed at improving physicians' sick-listing skills, arranged in different parts of Sweden. Before the course the participants, general practitioners (GP) sent in a written report of a sick-listing case they found problematic. The material consisted of group discussions of some 100 case reports from GPs. The process of categorisation of the dilemmas was a one-step, straightforward qualitative analysis. RESULTS Eight different categories of sick-listing dilemmas experienced by the physicians were identified. Examples of them are "Not the doctors' pigeon" (when the patients' problem was perceived as not being medical in nature), "Diagnosis as disguise" (when there is a discrepancy between how the patient describes the problems and what the physician apprehends), and "Harmed by sick listing-reversible" (when the physician perceives that the main problem is the iatrogenic adverse effects of sick listing per se). IMPLICATIONS The contribution of the study is to provide understanding of and labels to the specific difficulties experienced by physicians in their sick-listing practice face to face with patients.
The First Draft Genome of the Plasterer Bee Colletes gigas (Hymenoptera: Colletidae: Colletes)

Abstract Despite intense interest in bees, no genomes are available for the bee family Colletidae. Colletes gigas, one of the largest species of the genus Colletes in the world, is an ideal candidate to fill this gap. Endemic to China, C. gigas has been the focus of studies on its nesting biology and pollination of the economically important oil tree Camellia oleifera, which is chemically defended. To enable deeper study of its biology, we sequenced the whole genome of C. gigas using single-molecule real-time sequencing on the Pacific Bioscience Sequel platform. In total, 40.58 G (150×) of long reads were generated and the final assembly of 326 scaffolds was 273.06 Mb with a N50 length of 8.11 Mb, which captured 94.4% complete Benchmarking Universal Single-Copy Orthologs. We predicted 11,016 protein-coding genes, of which 98.50% and 84.75% were supported by protein- and transcriptome-based evidence, respectively. In addition, we identified 26.27% of repeats and 870 noncoding RNAs. The bee phylogeny with this newly sequenced colletid genome is consistent with available results, supporting Colletidae as sister to Halictidae when Stenotritidae is not included. Gene family evolution analyses identified 9,069 gene families, of which 70 experienced significant expansions (33 families) or contractions (37 families), and it appears that olfactory receptors and carboxylesterase may be involved in specializing on and detoxifying Ca. oleifera pollen. Our high-quality draft genome for C. gigas lays the foundation for insights on the biology and behavior of this species, including its evolutionary history, nesting biology, and interactions with the plant Ca. oleifera.
Effects of ants on water and soil losses from organically-managed citrus orchards in eastern Spain

Ants can play a key role in the erosion processes on agriculture land by modifying soil properties and increasing macropore flow. Ants are abundant in organically-managed orchards in the Mediterranean region due to climate conditions, no-till practices, no pesticide use, and the resulting vegetation cover. In order to determine the effect of ants on soil and water losses from these orchards growing on moderately-sloped land (4–8%), forty 1.0 m2 plots (20 with ants mounts and 20 without ants — controls) were established during the summer of 2007. A rainfall simulator was used to apply 78 mm of water to each plot over a one-hour period, equivalent to a 20-year return-period thunderstorm. Runoff was collected at 1-minute intervals and sediment concentration measured every 10 minutes. Sediment concentrations were 300% higher on plots with ant mounds, but runoff rates were similar to the plots without ants. Average soil erosion rates averaged 41 kg ha−1 h−1 on the ant plots and 13 kg ha−1 h−1 on the control plots. The low erosion rates are due to the effect of the vegetation and litter cover in this organically-managed soil, which were little impacted by ant activity at the pedon scale.
Rho kinase inhibitors: a patent review (2014 – 2016)

ABSTRACT Introduction: The Rho-kinases (ROCK), ROCK1 and ROCK2, are potent, widespread biochemical modulators which have been extensively studied. Due to the involvement of ROCKs in multiple biological processes, ROCK inhibitors have pleiotropic actions and may be of relevance for a number of therapeutic applications. The drawback is however that their use might be limited by occurrence of side effects. Areas covered: Since the publication of the latest review in 2014, there have been significant advances in the field of ROCK inhibitors. In this paper we reviewed the patents published between September 2013 and September 2016. Recent novel molecules will be described. and progress from the compounds series described in the previous review as well as any new expected therapeutic uses for ROCK inhibitors that popped up in the last three years will be examined. Expert opinion: While a number of potential applications in human for ROCK inhibitors have been reported, very few molecules are currently available to patients. In addition to fasudil, ripasudil (K-115, Kowa) was only recently approved in Japan for the treatment of glaucoma (2014). Notwithstanding some failures and subsequent discontinuation, the Pipeline of preclinical and clinical ROCK inhibitors remains significant.
The susceptibility of the knee extensors to eccentric exercise‐induced muscle damage is not affected by leg dominance but by exercise order

The aims of this study were first to compare the response of dominant and non‐dominant legs to eccentric exercise and second, to examine whether there is an effect of exercise order on the magnitude of symptoms associated with intense eccentric protocols. Eighteen young men performed three sets of 30 maximal eccentric isokinetic (60° s−1) contractions of the knee extensors (range of motion, ROM: 0°–100°, 0 = full extension) using either dominant or non‐dominant leg. They repeated a similar eccentric bout using the contralateral leg 6 weeks later. The sequence of leg's use was allocated to create equally balanced groups. Four indirect markers of muscle damage including subjective pain intensity, maximal isometric strength, muscle stiffness and plasma creatine kinase (CK) activity were measured before and 24 h after exercise. All markers changed significantly following the eccentric bout performed either by dominant or non‐dominant legs, but no significant difference was observed between legs. Interestingly, the comparison between the first and second eccentric bouts revealed that muscle soreness (−42%, P<0·001), CK activity (−62%, P<0·05) and strength loss (−54%, P<0·01) were significantly lower after the second bout. This study suggests that leg dominance does not influence the magnitude of exercise‐induced muscle damage and supports for the first time the existence of a contralateral protection against exercise‐induced muscle damage in the lower limbs.
ACTH after 15 min distinguishes between Cushing's disease and ectopic Cushing's syndrome: a proposal for a short and simple CRH test.

OBJECTIVE The aim of the present study was to validate criteria of corticotropin-releasing hormone (CRH) stimulation and 8 mg dexamethasone suppression (high-dose dexamethasone suppression, HDDS) to distinguish the etiology of ACTH-dependent Cushing's syndrome. SUBJECTS AND METHODS We retrospectively analyzed cortisol and ACTH after the injection of 100 μg human CRH in confirmed Cushing's disease (CD, n=78) and confirmed ectopic Cushing's syndrome (ECS, n=18). Cortisol and ACTH increase (in percentage above basal (%B)) at each time point, maximal increase (Δmax %B), and area under the curve (AUC %B) were analyzed using receiver operator characteristics (ROC) curve analyses. Cortisol suppression (%B) after 8 mg of dexamethasone was evaluated as a supplementary criterion. RESULTS An increase in ACTH of ≥ 43%B at 15 min after CRH was the strongest predictor of CD, with a positive likelihood ratio of 14.0, a sensitivity of 83%, a specificity of 94%, a positive predictive value of 98% and a negative predictive value of 58%. All of the other criteria of stimulated ACTH and cortisol levels were not superior in predicting CD in response to CRH injection. The addition of cortisol suppression by dexamethasone did not increase the discriminatory power. However, the combination of a positive ACTH response at 15 min and a positive HDDS test excluded ECS in all cases. CONCLUSION The present findings support the use of plasma ACTH levels 15 min after the injection of human CRH as a response criterion for distinguishing between CD and ECS. The addition of the HDDS test is helpful for excluding ECS when both tests are positive.
Heterogeneous Nuclear Ribonucleoproteins C1 and C2 Associate with the RNA Component of Human Telomerase

ABSTRACT Here we demonstrate that heterogeneous nuclear ribonucleoproteins (hnRNPs) C1 and C2 can associate directly with the integral RNA component of mammalian telomerase. The binding site for hnRNPs C1 and C2 maps to a 6-base uridylate tract located directly 5′ to the template region in the human telomerase RNA (TR) and a 4-base uridylate tract directly 3′ to the template in the mouse TR. Telomerase activity is precipitated with antibodies specific to hnRNPs C1 and C2 from cells expressing wild-type human TR but not a variant of the human TR lacking the hnRNPs C1 and C2 binding site, indicating that hnRNPs C1 and C2 require the 6-base uridylate tract within the human TR to associate with the telomerase holoenzyme. In addition, we demonstrate that binding of hnRNPs C1 and C2 to telomerase correlates with the ability of telomerase to access the telomere. Although correlative, these data do suggest that the binding of hnRNPs C1 and C2 to telomerase may be important for the ability of telomerase to function on telomeres. The C proteins of the hnRNP particle are also capable of colocalizing with telomere binding proteins, suggesting that the C proteins may associate with telomeres in vivo. Therefore, human telomerase is capable of associating with core members of the hnRNP family of RNA binding proteins through a direct and sequence-specific interaction with the human TR. This is also the first account describing the precise mapping of a sequence in the human TR that is required to associate with an auxiliary component of the human telomerase holoenzyme.
Re-examination of “release-from-PI” phenomena: recall accuracy does not recover after a semantic switch

ABSTRACT Recall accuracy decreases over successive memory trials using similar memoranda. This effect reflects proactive interference (PI) – the tendency for previously studied information to reduce recall of new information. However, recall improves if memoranda for a subsequent trial are semantically dissimilar from the previous trials. This improvement is thought to reflect a release from PI. We tested whether PI is reduced or released from the semantic category for which it had been induced by employing paradigms which featured inducement, semantic switch, and then return-to-original category epochs. Two experiments confirmed that PI was not released after various semantic switch trials (effects from d = −0.93 to −1.6). Combined analyses from both studies demonstrated that the number of intervening new category trials did not reduce or release PI. In fact, in all conditions recall accuracy decreased, demonstrating that PI is maintained and can increase after the new category trials. The release-from-PI account cannot accommodate these broader dynamics of PI. This account is also incongruent with evidence and theory from cognitive psychology, linguistics, and neuroscience. We propose a reintroduction-of-PI account which explains these broader PI dynamics and is consistent with the wider psychological and neurosciences.
Acrolein-induced dyslipidemia and acute-phase response are independent of HMG-CoA reductase.

SCOPE Aldehydes are ubiquitous natural constituents of foods, water and beverages. Dietary intake represents the greatest source of exposure to acrolein and related aldehydes. Oral acrolein induces dyslipidemia acutely and chronically increases atherosclerosis in mice, yet the mechanisms are unknown. Because lipid synthesis and trafficking are largely under hepatic control, we examined hepatic genes in murine models of acute and chronic oral acrolein exposure. METHODS AND RESULTS Changes in hepatic gene expression were examined using a Steroltalk microarray. Acute acrolein feeding modified plasma and hepatic proteins and increased plasma triglycerides within 15 min. By 6 h, acrolein altered hepatic gene expression including Insig1, Insig2 and Hmgcr genes and stimulated an acute-phase response (APR) with up-regulation of serum amyloid A genes (Saa) and systemic hypoalbuminemia. To test if decreased HMG-CoA reductase activity could modify acrolein-induced dyslipidemia or the APR, mice were pretreated with simvastatin. Statin treatment, however, did not alter acrolein-induced dyslipidemia or hypoalbuminemia associated with an APR. Few hepatic genes were dysregulated by chronic acrolein feeding in apoE-null mice. These studies confirmed that acute acrolein exposure altered expression of hepatic genes involved with lipid synthesis and trafficking and APR, and thus, indicated a hepatic locus of acrolein-induced dyslipidemia and APR that was independent of HMG CoA-reductase. CONCLUSION Dietary intake of acrolein could contribute to cardiovascular disease risk by disturbing hepatic function.
Enabling patient-centered care through health information technology.

OBJECTIVES The main objective of the report is to review the evidence on the impact of health information technology (IT) that supports patient-centered care (PCC) on: health care processes; clinical outcomes; intermediate outcomes (patient or provider satisfaction, health knowledge and behavior, and cost); responsiveness to needs and preferences of patients; shared decisionmaking and patient-clinician communication; and access to information. Additional objectives were to identify barriers and facilitators for using health IT to deliver PCC, and to identify gaps in evidence and information needed by patients, providers, payers, and policymakers. DATA SOURCES MEDLINE®, Embase®, Cochrane Library, Scopus, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, INSPEC, and Compendex databases through July 31, 2010. METHODS Paired members of our team reviewed citations to identify randomized controlled trials of PCC-related health IT interventions and studies that addressed barriers and facilitators for health IT for delivery of PCC. Independent assessors rated studies for quality. Paired reviewers abstracted data. RESULTS The search identified 327 eligible articles, including 184 articles on the impact of health IT applications implemented to support PCC and 206 articles addressing barriers or facilitators for such health IT applications. Sixty-three articles addressed both questions. The study results suggested positive effects of PCC-related health IT interventions on health care process outcomes, disease-specific clinical outcomes (for diabetes mellitus, heart disease, cancer, and other health conditions), intermediate outcomes, responsiveness to the needs and preferences of patients, shared decisionmaking, patient-clinician communication, and access to medical information. Studies reported a number of barriers and facilitators for using health IT applications to enable PCC. Barriers included: lack of usability; problems with access to the health IT application due to older age, low income, education, cognitive impairment, and other factors; low computer literacy in patients and clinicians; insufficient basic formal training in health IT applications; physicians' concerns about more work; workflow issues; problems related to new system implementation, including concerns about confidentiality of patient information; depersonalization; incompatibility with current health care practices; lack of standardization; and problems with reimbursement. Facilitators for the utilization of health IT included ease of use, perceived usefulness, efficiency of use, availability of support, comfort in use, and site location. CONCLUSIONS Despite marked heterogeneity in study characteristics and quality, substantial evidence exists confirming that health IT applications with PCC-related components have a positive effect on health care outcomes. positive effect on health care outcomes.
Inhibition of PP2A, but not PP5, mediates p53 activation by low levels of okadaic acid in rat liver epithelial cells

The microbial toxin okadaic acid (OA) specifically inhibits PPP‐type ser/thr protein phosphatases. OA is an established tumor promoter with numerous cellular effects that include p53‐mediated cell cycle arrest. In T51B rat liver epithelial cells, a model useful for tumor promotion studies, p53 activation is induced by tumor‐promoting (low nanomolar) concentrations of OA. Two phosphatases sensitive to these concentrations of OA, PP2A and protein phosphatase 5 (PP5), have been implicated as negative regulators of p53. In this study we examined the respective roles of these phosphatases in p53 activation in non‐neoplastic T51B cells. Increases in p53 activity were deduced from levels of p21 (cip1) and/or the rat orthologue of mdm2, two p53‐regulated gene products whose induction was blocked by siRNA‐mediated knockdown of p53. As observed with 10 nM OA, both phospho‐ser15‐p53 levels and p53 activity were increased by 10 µM fostriecin or SV40 small t‐antigen. Both of these treatments selectively inhibit PP2A but not PP5. siRNA‐mediated knockdown of PP2A, but not PP5, also increased p53 activity. Finally, adenoviral‐mediated over‐expression of an OA‐resistant form of PP5 did not prevent increased phospho‐ser15‐p53, p53 protein, or p53 activity caused by 10 nM OA. Together these results indicate that PP5 blockade is not responsible for OA‐induced p53 activation and G1 arrest in T51B cells. In contrast, specific blockade of PP2A mimics p53‐related responses to OA in T51B cells, suggesting that PP2A is the target for this response to OA. J. Cell. Biochem. © 2006 Wiley‐Liss, Inc.
A Meta-Analysis on the Diagnostic Performance of 18F-FDG and 11C-Methionine PET for Differentiating Brain Tumors

SUMMARY: 18F-FDG-PET has been widely used in patients with brain tumors. However, the reported sensitivity and specificity of 18F-FDG-PET for brain tumor differentiation varied greatly. We performed this meta-analysis to systematically assess the diagnostic performance of 18F-FDG-PET in differentiating brain tumors. The diagnostic performance of 11C-methionine PET was assessed for comparison. Relevant studies were searched in PubMed/MEDLINE, Scopus, and China National Knowledge Infrastructure (until February 2013). The methodologic quality of eligible studies was evaluated, and a meta-analysis was performed to obtain the combined diagnostic performance of 18F-FDG and 11C-methionine PET with a bivariate model. Thirty eligible studies, including 5 studies with both 18F-FDG and 11C-methionine PET data were enrolled. Pooled sensitivity, pooled specificity, and area under the receiver operating characteristic curve of 18F-FDG-PET (n = 24) for differentiating brain tumors were 0.71 (95% CI, 0.63–0.78), 0.77 (95% CI, 0.67–0.85), and 0.80. Heterogeneity was found among 18F-FDG studies. Subsequent subgroup analysis revealed that the disease status was a statistically significant source of the heterogeneity and that the sensitivity in the patients with recurrent brain tumor was markedly higher than those with suspected primary brain tumors. Pooled sensitivity, pooled specificity, and area under the receiver operating characteristic of 11C-methionine PET (n = 11) were 0.91 (95% CI, 0.85–0.94), 0.86 (95% CI, 0.78–0.92), and 0.94. No significant statistical heterogeneity was found among 11C-methionine studies. This meta-analysis suggested that 18F-FDG-PET has limited diagnostic performance in brain tumor differentiation, though its performance may vary according to the status of brain tumor, whereas 11C-methionine PET has excellent diagnostic accuracy in brain tumor differentiation.
Disruption of the determinant hierarchy on a self-MHC peptide: concomitant tolerance induction to the dominant determinant and priming to the cryptic self-determinant.

The presentation of self-peptides in a self-restricted manner plays a critical role in the complex positive and negative selective process of T cell recognition of self-determinants. The population of determinants comprises (i) a dominant set which is efficiently presented and induces clonal elimination or inactivation of the corresponding autoreactive T cells, and (ii) a cryptic set which is not processed efficiently enough to reach the threshold of presentation to make an impact on the T cell repertoire during thymic selection. Here we have studied a self-MHC peptide, Ld 61-85, which as shown in earlier work was able to induce vigorous T cell proliferation in syngeneic animals. Despite the fact that this peptide as a whole is 'cryptic', the fine specificity of the class II restricted response was complex, in that there were three distinct and overlapping T cell determinants: the dominant determinant, Ld 65-80, flanked by two cryptic determinants, Ld 61-75 and Ld 73-85, all of which compete for stimulating in vivo autoreactive T cell proliferative responses. The hierarchy of these determinants bears an interesting relationship to tolerance. Ld 61-85 or Ld 61-80 priming induces proliferation only to Ld 65-80; likewise, tolerance induction to Ld 61-80 prevents elicitation of a subsequent response to Ld 61-80 or Ld 65-80 in the local lymph nodes. However, in the Ld 61-80 tolerant mice, in vivo challenge with Ld 61-80 induces a strong T cell proliferative response directed towards cryptic Ld 61-75. (ABSTRACT TRUNCATED AT 250 WORDS)
Community Detection Using Dual-Representation Chemical Reaction Optimization

Many complex networks have been shown to have community structures. Detecting those structures is very important for understanding the organization and function of networks. Because this problem is NP-hard, it is appropriate to resort to evolutionary algorithms. Chemical reaction optimization (CRO) is a novel evolutionary algorithm inspired by the interactions among molecules during chemical reactions. In this paper, we propose a CRO variant named dual-representation CRO (DCRO) to address the community detection problem. DCRO encodes a solution in two representations: one is locus-based and the other is vector-based. The former representation can ensure the validity of a solution and fits for diversification search, and the latter is convenient for intensification search. We thus design two operators for CRO based on these two representations. Their cooperation enables DCRO to achieve a good balance between exploration and exploitation. Experimental results on synthetic and real-life networks show that DCRO can find community structures close to the actual ones and is capable of achieving solutions comparable to several state-of-the-art methods.
