Performance of the 2010 ACR/EULAR classification criteria for rheumatoid arthritis: a systematic literature review

Background The 2010 ACR/EULAR classification criteria for rheumatoid arthritis (RA) were developed to improve the identification of individuals for studies of RA. We aimed to summarise the performance of the criteria based on the published literature. Methods We performed a systematic literature search to identify all studies investigating the 2010 criteria and reporting data allowing to calculate sensitivity (SENS), specificity (SPEC), and positive and negative predictive values. Where possible, meta-analysis was performed. Results Seventeen full articles (total 6816 patients) and 17 meeting abstracts (total 4004 patients) fulfilled the inclusion criteria. Pooled sensitivity and specificity for RA (defined by different reference standards) were 0.82 (95% CI 0.79–0.84) and 0.61 (0.59–0.64). Results were comparable for different reference standards: for initiation of methotrexate pooled sensitivity was 0.85 (0.83–0.86) and specificity was 0.52 (0.49–0.54); for initiation of any disease modifying antirheumatic drug they were 0.80 (0.79–0.82) and 0.65 (0.61–0.68), respectively; and for expert opinion 0.88 (0.86–0.90) and 0.48 (0.35–0.52). No differences were observed for use of different types of joint counts. Eight studies and five meeting abstracts directly compared 1987 and 2010 criteria using different reference standards within different target populations showing higher overall sensitivity (+0.11 compared with 1987 criteria) at the cost of lower overall specificity (–0.04). Conclusions Two years after their publication, the 2010 ACR/EULAR criteria have been widely tested in the community. They are sensitive to detect cases of RA among various target populations, independent of how the latter is referenced.
Milk Drinking and Mortality: Findings From the Japan Collaborative Cohort Study

Background Findings regarding the association between milk consumption and all-cause mortality reported by studies carried out in Western populations have been inconsistent. However, no studies have been conducted in Japan on this issue. The present study aimed to investigate the association of milk drinking with all-cause, cardiovascular, and cancer mortality in Japan. Methods The data were obtained from the Japan Collaborative Cohort (JACC) study. A total of 94 980 Japanese adults aged 40–79 years who had no history of cancer, stroke, or chronic cardiovascular diseases were followed between 1988 and 2009. Multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of mortalities were assessed using a Cox proportional hazard regression model and taking the lowest milk consumption group as the reference. Results During a median of 19 years of follow-up, there were 21 775 deaths (28.8% and 35.3% from cardiovascular diseases and cancer, respectively). Drinking milk 1–2 times a month was associated with lower all-cause mortality in men compared to those who never drank milk (multivariable-adjusted HR 0.92; 95% CI, 0.85–0.99). In women, those who drank 3–4 times a week also had a lower mortality risk compared with those who never drank milk (HR 0.91; 95% CI 0.85–0.98). Inverse associations between drinking milk and mortality from cardiovascular diseases and cancer were found only in men. Conclusions Drinking milk at least 1–2 times a month was associated with lower all-cause mortality in men compared to never drinking milk. An inverse association was also found between drinking milk and mortality from both cardiovascular diseases and cancer. However, lower all-cause mortality in women was found only in those who drank milk 3–4 times/week.
The neonatal Fc receptor is not required for mucosal infection by mouse mammary tumor virus

The milk-borne mouse mammary tumor virus (MMTV) infects newborn mice via the intestine. Infection is initially restricted to Peyer's patches and later spreads to the epithelial cells of the mammary gland. The receptor that mediates uptake and transport of MMTV across the intestinal barrier has not yet been identified, The neonatal Fc receptor (nFcR), which is expressed by enterocytes during the first two weeks of life, is downregulated at weaning, and its disappearance correlates with the onset of intestinal resistance to MMTV. To test whether the nFcR mediates transport and allows infection, we foster nursed on infected MMTV mothers beta2 microglobulin-deficient (beta2m-deficient) newborn mice that are unable to express the nFcR at the surface of their enterocytes. Exposure of beta2m-deficient mice to milk-borne virus resulted in the deletion of peripheral blood T cells reactive to the superantigen encoded by MMTV. Since beta2m-deficient newborn mice are susceptible to MMTV infection despite the lack of the nFcR, we conclude that the nFcR is not required for MMTV transport.
Unraveling the resistance of microbial biofilms: Has proteomics been helpful?

Biofilms are surface‐attached, matrix‐encased, structured microbial communities which display phenotypic features that are dramatically different from those of their free‐floating, or planktonic, counterparts. Biofilms seem to be the preferred mode of growth of microorganisms in nature, and at least 65% of all human infections are associated with biofilms. The most notable and clinically relevant property of biofilms is their greater resistance to antimicrobials compared with their planktonic counterparts. Although both bacterial and fungal biofilms display this phenotypic feature, the exact mechanisms underlying their increased drug resistance are yet to be determined. Advances in proteomics techniques during the past decade have facilitated in‐depth analysis of the possible mechanisms underpinning increased drug resistance in biofilms. These studies have demonstrated the ability of proteomics techniques to unravel new targets for combating microbial biofilms. In this review, we discuss the putative drug resistance mechanisms of microbial biofilms that have been uncovered by proteomics and critically evaluate the possible contribution of the new knowledge to future development in the field. We also summarize strategic uses of novel proteomics technologies in studies related to drug resistance mechanisms of microbial biofilms.
Cervical dilatation at the time of cesarean section may affect the success of a subsequent vaginal delivery

Objective. To evaluate the effect of labor progress prior to cesarean delivery on the outcome of vaginal birth after cesarean delivery (VBAC). Methods. The medical records of women attempting VBAC between January 2000 and February 2008 were reviewed. All women had only one previous cesarean and underwent spontaneous labor. Results. Among 1148 enrolled women, 956 (83.3%) achieved a successful VBAC. Birth weight, previous indication for cesarean delivery and oxytocin augmentation were significantly associated with VBAC outcome. By multivariate analysis, a cervical dilatation ≥8 cm at previous cesarean was independently predictive of successful VBAC in women with a previous cesarean for non-recurrent indications (p = 0.046), yielding a VBAC success rate of 93.1%, whereas the extent of cervical dilatation at the previous cesarean did not affect the outcome of subsequent delivery in women with a previous cesarean for recurrent indications. Conclusions. Women with cesarean for non-recurrent indications who achieved a cervical dilatation ≥8 cm may be the best candidates for VBAC, with the greatest likelihood of a successful VBAC. Labor progress at previous cesarean can serve as a valuable indicator for VBAC outcome in women with a previous cesarean for non-recurrent indications, and therefore should be discussed as part of preconception counseling.
Research on Influence of Shopping APP’s Characteristic on Consumer’s Impulse Buying

Based on the SOR theory, this study examined the influence of the knowledge, convenience and entertainment of APP on the consumer’s intention to buy, with 624 consumers who had APP shopping experience. The mediating variable of this study was the sense of pleasure and arousal of psychological emotion. The study findings showed that: 1) shopping APP’s knowledge, convenience and entertainment represented the most obvious features of shopping APP; 2) pleasure was completely mediated by the shopping APP’s knowledge and entertainment on impulse buying intention, partly mediated by the convenience on impulse buying intention; 3) arousal was completely mediated by the shopping APP’s knowledge and convenience on impulse buying intention, partly mediated by the entertainment on impulse buying intention.
Early appearance of serum -fetoprotein as a function of dosage of various hepatocarcinogens.

A previously reported early appearance of alpha fetoprotein (AFP) in rats fed 3'-methyl-4-dimethylaminobenzene (3-MDAB) which was induced before definite cancers were formed and disappeared on cessation of 3-MDAB administration was further investigated using different doses of 3-MDAB as well as other hepatocellular carcinogens and hepatotoxic agents. AFP was induced after 3 weeks of ingestion of diets with 600 ppm 3-MDAB and appeared after only 2 weeks when higher doses (900 and 1200 ppm) were used. Lower levels of 300 ppm 3-MDAB gave only a transient appaerance of AFP, beginning at the 5th week and remaining detectable for 3 more weeks, but 150 ppm did not induce at all. Immunosuppression with rat lymphocyte globulin extended for 1 week the time during which positive AFP titers were maintained upon cessation of 3-MDAB (600 ppm) intake. A transient appearance of AFP was found when rats were given the carcinogens dimethyl-4-dimethylaminoazobenzene (4-DMAA; 600 ppm), aflatoxin (AFB1; 4 ppm), N-2-fluorenylacetamide (N-2-FAA; 200 and 300 ppm), and N-hydroxy-N-2-fluorenylacetamide (N-OHFAA; 213 and 320 ppm). Lower doses of AFB1 (.2 and 2 ppm), N-2-FAA (150 ppm), N-OHFAA, and diethylnitrosamine (40 ppm) did not induce detectable AFP levels in serum nor did 2'-methyl-4-DMAA (600 ppm) and CCl4 (50 mg intraperitoneally twice a week). Apparently, high levels of liver carcinogens are required to induce the early appearance, within 2-5 weeks, of detectable AFP in serum.
MIDDLE EAR FUNCTION OF NEONATES

Results of impedance audiometry can determine middle ear pressure, eustachian tube function, tympanic membrane mobility, and presence of fluid in the middle ear cavity. The present study utilized an impedance audiometer to measure middle ear function of neonates.Subjects included 20 infants with a mean age of 7.4 hrs. Their average weight was 3120 grams. All were healthy with no obvious congenital defects. Both ears were tested on every baby. The vernix caseosa was removed from the external auditory meatus prior to taking impedance measurements.Results indicated that all of the infants had normal tympanic membrane mobility and normal middle ear pressure. The data show 33 ears with Type Ad tympanograms and 7 Type W tympanograms. The average middle ear pressure was 6.75 mm. (H2O). The average compliance at the tympanic membrane was 1.113 cu. cm.Many pediatric textbooks state that the middle ear of neonates is filled with a mucoid material which is present for the first few days of life and is a factor in the ability of newborns to respond to sound. The finding of normal middle ear function in neonates would suggest that mucous is not commonly present and therefore not a factor in infant's response to sound.
Differential Expression and Subcellular Localization of Claudin-7, −8, −12, −13, and −15 Along the Mouse Intestine

Among tight-junction proteins, claudins, which play a key role in paracellular transport across epithelia, claudins 1 to 5 are expressed in the intestine, and changes in their abundance and/or distribution are considered to contribute to various gastrointestinal diseases. We investigated, by reverse transcription-PCR, immunoblot, and immunofluorescence analyses, which other claudin species were expressed in the mouse intestine, and whether they showed unique expression profiles. Rabbit polyclonal antibodies against mouse claudin-8, claudin-12, and claudin-15 were generated, and their specificity was verified by immunoblotting using COS-7 cells transfected with individual claudin cDNAs. Claudin-7, −8, −12, −13, and −15 appeared to be expressed in the duodenum, jejunum, ileum, and/or colon with remarkable variations in the expression levels along the intestinal tract, and had distinct subcellular localization in the intestinal epithelium. In addition, claudin-13 and −15 exhibited gradients along the crypt-surface axis of the colon. By contrast, claudin-6, −9, −10, −11, −14, −16, −18, and −19 were not observed in the intestine. Our results indicate that five additional species of claudins have very complex expression patterns along and within the intestine, and that this may reflect differences in paracellular permeable properties, providing valuable resources for studying the significance of these claudins in gastrointestinal disorders.

Coronary stenting during rescue angioplasty after failed thrombolysis

Compared with primary angioplasty [percutaneous transluminal coronary angioplasty (PTCA)], rescue PTCA is associated with lower angiographic success and higher reocclusion rates, especially after thrombolysis with tissue‐type plasminogen activator (tPA). Although stent placement during primary PTCA has been demonstrated to be safe and even to improve the angiographic results achieved by balloon‐alone PTCA, there are few data on stent placement during rescue PTCA after failed thrombolysis. This study sought to assess the feasibility and safety of stent implantation during rescue angioplasty in myocardial infarction after failed thrombolysis. The study population consisted of 20 patients with acute myocardial infarction referred for rescue PTCA after failed thrombolysis consecutively treated with coronary stenting. The thrombolytic agent was tPA in 15 patients (75%), streptokinase in 1 (5%), and anisoylated streptokinase plasminogen activator complex (APSAC) in 1 (5%); 3 patients (15%) were included in the INTIME II study (tPA vs. lanoteplase). After stenting, aspirin 200 mg daily plus ticlopidine 250 mg b.i. d. were administered. Thirty stents (1.5 ± 1.0 per patient) were implanted. Angiographic success was achieved in 19 patients (95%). Two patients (10%) died, both because of severe bleeding complications. One patient (5%) suffered a reinfarction, but no patients suffered postinfarction angina or needed new target vessel revascularization. Eighteen patients (90%) were discharged alive and free of events. All these patients remained asymptomatic and free of target vessel revascularization at 6‐month follow‐up. Stent placement during rescue PTCA after failed thrombolysis is feasible and safe and is associated with a good angiographic result and clinical outcome. Bleeding complications seem to be, however, the main limitation of this reperfusion strategy. Cathet. Cardiovasc. Intervent. 47:1–5, 1999. © 1999 Wiley‐Liss, Inc.
An Evaluation of Patient-Physician Communication Style During Telemedicine Consultations

Background The quality of physician-patient communication is a critical factor influencing treatment outcomes and patient satisfaction with care. To date, there is little research to document the effect of telemedicine (TM) on physician-patient communication. Objective The objectives of this study are to measure and describe verbal and nonverbal communication during clinical TM consultations and to compare TM with in-person (IP) consultations in terms of the quality of physician-patient communication. Methods Veteran patients (n = 19) requiring pulmonary medicine consultations were enrolled into the study. The study group included 11 patients from the Iron Mountain Veterans Affairs Hospital (VAMC) remote site. Patients had individual TM consultations with a pulmonary physician at the Milwaukee VAMC hub site. A control group of 8 patients had IP consultations with a pulmonary physician at the Milwaukee VAMC. Video recordings of medical consultations were coded for patient-physician verbal and nonverbal communication patterns using the Roter Interaction Analysis System (RIAS). Results There were no differences in the length of TM consultations (22.2 minutes) and IP consultations (21.9 minutes). Analysis of visit dialogue indicated that the ratio of physician to patient talk was 1.45 for TM and 1.13 for IP consultations, indicating physician verbal dominance. Physicians were more likely to use orientation statements during IP consultations (P = .047). There were greater requests for repetition from patients during TM consultations (P = .034), indicating perceptual difficulties. Conclusions The study findings indicate differences between TM and IP consultations in terms of physician-patient communication style. Results suggest that, when comparing TM and IP consultations in terms of physician-patient communication, TM visits are more physician centered, with the physician controlling the dialogue and the patient taking a relatively passive role. Further research is needed to determine whether these differences are significant and whether they have relevance in terms of health outcomes and patient satisfaction with care.
Expression of the H-ras oncogene induces potassium conductance and neuron-specific potassium channel mRNAs in the AtT20 cell line

Expression of the EJ-ras oncogene in the AtT20 cell line results in several changes in their properties that correspond to a switch of these anterior pituitary-derived cells to a more neuronlike phenotype. The width of action potentials following transfection with ras is reduced 20-fold from over 200 msec in control AtT20 cells to less than 10 msec in ras-transfected cells. This is associated with a two- to threefold increase in the density of voltage-dependent potassium currents. In addition, the rate of inactivation of these currents is decreased approximately twofold in ras-transfected cells. At least part of the change in potassium current may be due to differential expression of potassium channel mRNAs. In the ras-transfected cells, mRNA species were detected using a probe for the voltage-dependent potassium channels, Kv4, a species that appears to be uniquely expressed in the nervous system, and NGK2, an alternatively spliced product transcribed from the same gene. These mRNAs are not detected in control AtT20 cells. The results suggest that the ras protein modulates the phenotype of excitable cells by influencing the expression of specific potassium channels and thereby altering the density and types of channels in the plasma membrane.
Characterization of Aβ aggregation mechanism probed by congo red

β-Amyloid peptide 1 (Aβ) aggregates are toxic to neuron and the main cause of Alzheimer’s disease (AD). The role of congo red (CR) on Aβ aggregation is controversial in aqueous solution. Both prevention and promotion of Aβ aggregation have been proposed, suggesting that CR may interact with Aβ of different structural conformations resulting in different effects on Aβ aggregation behavior. CR with these characteristics can be applied to probe the molecular mechanism of Aβ aggregation. Therefore, in the present study, we used CR as a probe to study the Aβ aggregation behavior in sodium dodecyl sulfate (SDS) condition. Our results show that Aβ40 adopts two short helices at Q15-S26 and K28-L34 in the SDS environment. CR can interact with the helical form of Aβ40, and the main interaction site is located at the first helical and hydrophobic core region, residues 17–25, which is assigned as a discordant helix region. Furthermore, CR may prevent Aβ40 undergoing α-helix to β-strand conversion, and therefore aggregation through stabilizing the helical conformation of discordant helix in SDS environment, suggesting that the discordant helix plays a key role on the conformational stabilization of Aβ. Our present study implies that any factors or molecules that can stabilize the discordant helical conformation may also prevent the Aβ aggregation in membrane associated state. This leads to a new therapeutic strategy for the development of lead compounds to AD. 1These authors contributed equally to this work.
Sex-Related Wage Differentials and Women's Interrupted Labor Careers-the Chicken or the Egg

Wage differentials between men and women are often attributed to differences in on-the-job training, the lower investment of women being explained by their plans to interrupt their careers for family reasons. Career interruptions, however, are often explained by low wages. To trace this interrelationship, I adopt a simultaneous equations approach, trying to explain wages, planned separations, on-the-job training, and the skill intensity of the job simultaneously. Skill intensity is found to be a key variable in the explanation of the wage differential. Traditional theory is hard pressed to explain the sex-related differences in this variable.
Corruption, Privatisation and Economic Growth in Post-communist Countries

Abstract This article empirically investigates the effects of corruption and privatisation on economic growth in the post-communist countries of Central and Eastern Europe and the former USSR. We use a corruption and privatisation augmented open-economy leader–follower endogenous growth model to derive our research hypotheses. In this setting, corruption, privatisation and external openness jointly determine the per capita income in the follower economy. This model predicts that economies with higher shares of private ownership, lower corruption, and higher external openness enjoy higher rates of growth. Our empirical verification of these predictions is based on a panel of 29 post-communist countries during the period 1996–2014. Our estimation results confirm the negative effects of corruption, while the positive effects of privatisation are limited to small-scale privatisation.
Further information from a sonometric study of the normal tricuspid valve annulus in sheep: geometric changes during the cardiac cycle.

BACKGROUND AND AIM OF THE STUDY In a previous sono-metric study, changes were described that occurred in the normal tricuspid valve during the cardiac cycle. However, the wealth of data available suggested the need for reporting further findings that should contribute to a better understanding of the dynamics of the tricuspid valve. METHODS Thirteen sonomicrometry transducers were placed in the hearts of each of seven sheep. Six transducers were placed in the tricuspid annulus (TA), at the base of each leaflet, and at each commissure; three at the tips of the papillary muscles (PMs); three in the free edges of the leaflets; and one transducer was placed at the apex. Distances between transducers, pulmonary and right ventricular pressures, and pulmonary flow were recorded simultaneously. RESULTS The TA area underwent two major contractions and expansions during the cardiac cycle, reaching its maximum during isovolumic relaxation and its minimum in diastole. The TA height-to-width ratio changed from 8.4 +/- 1.9% to 15.3 +/- 4.2%. The leaflets began to open before end-systole. By the end of isovolumic relaxation, the leaflets had completed 54.1 +/- 13.4% of their opening. The PM and TA planes were not parallel, but were offset by 11.5 +/- 1.9 degrees to 17.8 +/- 2.1 degrees. The PM rotated 6.9 +/- 0.9 degrees with respect to the TA, with 3.1 +/- 1.1 degrees of the rotation occurring during ejection. CONCLUSION The tricuspid valve is not a passive structure but rather forms a dynamic part of the right ventricle. Its orifice area changes not only due to the contraction and expansion of its perimeter but also to changes in its saddle shape. Leaflet opening and closure is not simply a response to pressure. The PMs rotate in relation to the TA. These data should impact upon the diagnosis and surgery of functional tricuspid regurgitation.
