A growing population of older adults and improved effective treatments for inflammatory rheumatic diseases will increase the demand for more healthcare resources that already struggle with staggering outpatient clinic waiting times. Transformative delivery care models that provide sustainable healthcare services are urgently needed to meet these challenges. In this mini-review article, a proposed Lifelong Treatment Model for a decentralized follow-up of outpatient clinic patients living with rheumatoid arthritis is presented and discussed.Our conceptual model follows four steps for a transformative care delivery model supported by an Integrated Practice Unit; (1) Diagnosis, (2) Treatment, (3) Patient Empowered Disease Management, and (4) Telehealth. Through an Integrated Practice Unit, a multidisciplinary team could collaborate with patients with rheumatoid arthritis to facilitate high-value care that addresses most important outcomes of the patients; (1) Early Remission, (2) Decentralization, (3) Improved Quality of Life, and (4) Lifelong Sustain Remission.The article also addresses the growing challenges for the healthcare delivery system today for patients with rheumatoid arthritis and proposes how to reduce outpatient clinic visits without compromising quality and safety.

Neutral detergent fiber (NDF) is the most effective and measurable predictor of animal intake. About 70% of the variation in animal production is attributed to differences in intake potential of livestock feed. Sixteen molecular markers associated with NDF in four divergently selected smooth brumegrass (Bromus inermis L.) populations were selected from a previous study for further examination for possible use in a marker-assisted selection (MAS) breeding program. The objectives of this experiment were to confirm the association of previously identified markers to NDF concentration in smooth bromegrass populations and to develop a marker-based selection index. Marker and NDF data were analyzed and marker indices were constructed using data from the current and previous studies. Index scores were used to rank genotypes and create selection differentials on the basis of phenotypic data. Marker frequencies calculated on a subpopulation basis between the previous and current studies were highly unrepeatable. Nevertheless, of the 14 groups of marker indices, seven of which accounted for pedigree structure, one marker index appears to provide the greatest potential for use in MAS to reduce NDF across all four populations of smooth bromegrass. Where pedigree structure is known, selections made using this index would lead to the largest expected response per year and eliminate the need to collect phenotypic data for as long as linkage relationships remain intact. Where pedigree structure is unknown, a general marker index may be used, or phenotypic data can be utilized along with a marker index. However, inclusion of phenotypic data would necessitate a cost-benefit analysis., SMOOTH BROMEGRASS is a cool-season forage grass that was introduced to North America in 1884. It gained recognition during the droughts of the 1930s because of its ability to survive [...]

Kentucky bluegrass (Poa pratensis L.) is an important cool-season grass species in the turfgrass and forage industries. Understanding the genetics of Kentucky bluegrass is useful in developing improved cultivars and hybrids. However, studying the genetics of Kentucky bluegrass can often be difficult because of the high variation in ploidy level that results from its facultative apomictic reproductive nature. Flow cytometry provides an easy and accurate method for assessing this variation by quantifying DNA content. The purpose of our study was to determine the level of variation in ploidy in Kentucky bluegrass by analyzing its DNA content using flow cytometry. In addition, DNA content was compared with genetic similarity derived from DNA marker data, and was also correlated with chromosome number. Twenty-two cultivars of Kentucky bluegrass were selected for the study by considering the range of variability in morphological traits and genetic distance derived from DNA marker data. We found that the DNA content of Kentucky bluegrass genotypes from the 22 cultivats ranged from 5.39 to 17.69 pg of DNA/2C and that a majority of the genotypes had a DNA content value in the range of 7 to 13 pg. A significant correlation between DNA content and chromosome number was detected. Euploid chromosome numbers (x = 7) with a range from the pentaploid (2n = 5x = 35) to the quindecaploid (2n = 15x = 105) were found along with aneuploid numbers. The results of this research could aid both breeders and researchers in studying the genetics of the species and in improving Kentucky bluegrass cultivars via intra- and interspecific hybridizations., KENTUCKY BLUEGRASS is a cool-season grass that is used in many different environments. Kentucky bluegrass has a number of characteristics that make it highly valuable to various industries. It is [...]

Grasses -- Research ,Agricultural industry ,Business ,Research - Abstract
Kentucky bluegrass (Poa pratensis L.) is a widely used, facultatively apomictic, cool season turf and forage grass, with many known cultivars. Previously these have been classified on the basis of morphological traits in field tests. However, these determinations are lengthy, sensitive to environmental variations, and there are few traits that can be tested. Molecular markers provide an alternative way to classify these cultivars. Important advantages of molecular markers include lack of sensitivity to changes in environmental conditions, as well as a nearly unlimited potential number of markers and speed of the marker assays as compared with field tests. They can also provide additional information such as the amount of genetic divergence between Kentucky bluegrass cultivars and other genotypes, the amount of agreement between morphological and marker-based classification, and the amount of genetic variability between seedling replicates of genotypes. Random amplified polymorphic DNA (RAPD) marker data was collected from three replicates each of 123 Kentucky bluegrass cultivars, plant introductions (PIs), experimental breeding lines, and interspecific hybrids between Kentucky and Texas bluegrass (Poa arachnifera Torr.). From these data multidimensional scaling (MDS) plots were created, and ANOVA tests of significant differences between germplasm sources were performed. The PIs were the most genetically divergent from the cultivars, while the interspecific hybrids were not as distinct. Members of two morphological trait-based types were found to be genetically similar, and there was a wide range of genetic variability among germplasm sources. The genetic divergence of the PIs, combined with their potentially high turf utility reported in earlier studies, indicates their potential as a genetic resource. All but two of the morphological trait-based types contained genetically diverse individuals, so that cultivar blends of all but these two types would be morphologically similar yet genetically diverse. The rather high within-cultivar genetic variability could be due to a relatively high proportion of potentially sexually produced off-types. Thus, this study provides further evidence for the utility of RAPD markers for turfgrass genetics, as well as important genetic information for turf breeders and managers., KENTUCKY BLUEGLASS is commonly used throughout the world for applications such as golf courses, athletic fields, lawns, and permanent pastures (Murphy et al., 1997). It is vigorous and attractive, easily [...]

Bacterial brown spot (BBS), caused by Pseudomonas syringae pv. syringae van Hall (Pss), is an important bacterial disease of common bean (Phaseolus vulgaris L.). The objective of this study was to identify random amplified polymorphic DNA (RAPD) molecular markers linked to quantitative trait loci (QTLs) for BBS resistance. Resistance was assessed by three methods: (i) stem inoculations of plants grown in a greenhouse evaluated by a 1-to-5 rating scale for stem symptoms, (ii) percentage of BBS infected leaves per plot in noninoculated field trials, and (iii) Pss population sizes, on noninoculated field grown plants determined by a leaflet freezing assay (LFA). [F.sub.8:9] recombinant inbred fines derived from the Mesoamerican cross of Belneb RR-1 (susceptible to BBS) x A 55 (resistant to BBS) were grown in replicated experiments in two years (1996, 1998) in Wisconsin. In addition, two separate experiments were performed in the greenhouse in a randomized complete block design with two replicates for seedling stem inoculation with Pss strain Bs191. One genomic region on linkage group (LG) 2, from a previously published genetic linkage map, was significantly associated with QTLs for BBS resistance measured by three assays over two years. Phenotypic reactions were significantly correlated with the measurement of freezing temperatures as determined by LFA under a favorable environment for the growth of epiphytic bacterial populations. Marker assisted selection for resistance to BBS using molecular markers found during this study may improve selection efficiency for resistance because of the low heritability of the reaction to BBS, and the independent QTLs for resistance to different bacterial diseases. Furthermore, disease screening solely dependent upon natural field inoculations is not reliable because of genotype x environment interactions. The leaflet freezing assay method could be utilized to screen progenies or breeding germplasms, even when no distinct phenotypic disease symptoms are present on the plants., BACTERIAL BROWN SPOT is one of the important bacterial diseases affecting production of common bean in the USA (Hagedorn and Patel, 1965; Steadman and Schwartz, 1983).

Electric current converters -- Research ,Business ,Electronics ,Electronics and electrical industries - Abstract
For the generalization of quantum resonant converters, new quantum resonant modules--a quantum series resonant module (QSRM) and a quantum parallel resonant module (QPRM)--are proposed. The QSRM and QPRM are modeled as an equivalent inductor and an equivalent capacitor, respectively. The models of the proposed modules are useful in deriving the practical family of quantum resonant converters corresponding to the conventional PWM converters. The ac/ac quantum resonant converters are investigated as useful converters. The concept of modules and the validity of the modeling are confirmed by the experiment.

Background Morel-Lavallee lesions (MLLs) are rare internal degloving injuries typically caused by blunt traumatic injuries and most commonly occur around the hips and in association with pelvic or acetabular fractures. MLL is often overlooked in the setting of poly-trauma; therefore, clinicians must maintain a high degree of suspicion and be familiar with the management of such injuries, especially in obese poly-trauma patients. Case presentation We present a 30-year-old female pedestrian struck by a motor vehicle who sustained multiple long bone fractures, a mesenteric hematoma, and full-thickness abdominal skin friction burn which masked a significant underlying abdominal MLL. The internal degloving caused significant devascularization of the overlying soft tissue and skin which required surgical drainage of hematoma, abdominal wall reconstruction with tangential excision, allografting, negative pressure wound therapy, and ultimately autografting. Conclusion MLL is a rare, often overlooked, internal degloving injury. Surgeons must maintain a high index of suspicion when dealing with third degree friction burns as they may mask underlying injuries such as MLL, and a delay in diagnosis can lead to increased morbidity.

Background Secure messages exchanged between patients and family medicine residents via an electronic health record (EHR) could be used to assess residents' clinical and communication skills, but the mechanism is not well understood. Objective To design and test a secure messaging competency assessment for family medicine residents in a patient-centered medical home (PCMH). Methods Using the existing literature and evidence-based guidelines, we designed an assessment tool to evaluate secure messaging competency for family medicine residents training in a PCMH. Core faculty performed 2-stage validity and reliability testing (n = 2 and n = 9, respectively). A series of randomly selected EHR secure messages (n = 45) were assessed from a sample of 10 residents across all years of training. Results The secure message assessment tool provided data on a set of competencies and a framework for resident feedback. Assessment showed 10% (n = 2) of residents at the novice level, 50% (n = 10) as progressing, and 40% (n = 8) as proficient. The most common deficiencies for residents' secure messages related to communication rather than clinical competencies (n = 37 [90%] versus n = 4 [10%]). Interrater reliability testing ranged from 60% to 78% agreement and 20% to 44% disagreement. Disagreement centered on interpersonal communication factors. After 2 stages of testing, the assessment using residents' secure messages was incorporated into our existing evaluation process. Conclusions Assessing family medicine residents' secure messaging for patient encounters closed an evaluation gap in our family medicine program, and offered residents feedback on their clinical and communication skills in a PCMH.

INTRODUCTION Competence in using an electronic health record (EHR) is considered a critical skill for physicians practicing in patient-centered medical homes (PCMHs), but few studies have examined the impact of EHR training for residents preparing to practice in PCMHs. This study explored the educational outcomes associated with comprehensive EHR training for family medicine residents. METHODS The PCMH EHR training consisted of case-based routine clinic visits delivered to 3 resident cohorts (N = 18). Participants completed an EHR competency self-assessment between 2011 and 2016 (N = 127), examining 6 EHR/PCMH core skills. We compared baseline characteristics for residents by low vs high exposure to EHR training. Multivariate regression estimated whether self-reported competencies improved over time and whether high PCMH EHR training exposure was associated with incremental improvement in self-reported competencies over time. RESULTS Residents completed an average of 8.2 sessions: low-exposure residents averaged 5.3 sessions (standard deviation = 1.5), and high-exposure residents averaged 9.0 sessions (standard deviation = 0.9). High-exposed residents had higher posttest scores at training completion (84.4 vs 70.7). Over time, adjusted mean scores (confidence interval) for both groups improved (p < 0.001) from 12.2 (9.6-14.8), with low-exposed residents having greater score improvement (p < 0.001) because of their much lower baseline scores. CONCLUSION Comprehensive training designed to improve EHR competencies among residents practicing in a PCMH resulted in improved assessment scores. Our findings indicate EHR training as part of resident exposure to the PCMH measurably improves self-assessed competencies, even among residents less engaged in EHR training.

Implementing an innovation, such as offering new types of patient-physician encounters through the patient-centered medical home (PCMH) model while maintaining Accreditation Council for Graduate Medical Education (ACGME) accreditation standards (e.g., patient encounter minimums for trainees), is challenging.In 2009, the Group Health Family Medicine Residency (GHFMR) received an ACGME Program Experimentation and Innovation Project (PEIP) exception that redefined the minimum Family Medicine Resident Review Committee requirement to 1,400 face-to-face visits and 250 electronic visits (1 electronic visit defined as 3 secure message or telephone encounters). The authors report GHFMR residents' continuity clinic encounters, specifically volume, from 2006 through 2013 via pre- and post-PCMH implementation. They discuss the implications for leaders of high-performing practices who desire to innovate while maintaining accreditation.Post-PCMH residents had 20% more overall patient contact. The largest change in care delivery method included a large increase in secure messages between patients and residents. Pre-PCMH residents had more face-to-face encounters; however, post-PCMH residents had more contact for all types of patient care encounters (face-to-face, secure messaging, and telephone) per hour of clinic time.The ACGME PEIP exception, allowing the incorporation of the PCMH, facilitated an increase in patient access and immersed residents in primary care innovation (namely, practicing in a PCMH model during graduate medical education training). The next steps are to assess the effect of the PCMH on resident learning and clinical outcomes and to continue residents' access to training that keeps pace with today's health care delivery needs.

This study aimed to assess the types of vertebral segments at the thoracolumbar junction, as they relate to the most caudal ribs, to evaluate the reliability of this assessment using axial CT with curved planar reformatting (CPR) images, to describe the morphologic characteristics of a thoracolumbar transitional vertebra (TLTV), to introduce a new classification system for the TLTV and to evaluate the reliability of the classification system using axial CT with CPR images.This was a retrospective review of 744 consecutive patients who underwent spine CT imaging that included the thoracolumbar junction. Two radiologists (Readers 1 and 2) independently evaluated the axial CT with CPR images for all cases (n = 744). Each radiologist differentiated the vertebral segments at the thoracolumbar junction as TLTV or non-TLTV (thoracic segment or lumbar segment). In addition, each radiologist classified the 94 patients with the TLTV using a novel classification system. Interobserver agreement between the two radiologists regarding the differentiation of vertebral segments at the thoracolumbar junction was analysed with kappa statistics. Similarly, intra- and interobserver agreement regarding TLTV classification was analysed with kappa statistics.Interobserver agreement between the two readers with respect to the differentiation of vertebral segments at the thoracolumbar junction via axial CT with CPR images was nearly perfect (κ-value: 0.959). Interobserver agreement between the two readers with respect to TLTV classification using axial CT with CPR images was nearly perfect (κ-value: 0.846). In addition, intraobserver agreement for Reader 1 was also nearly perfect (κ-value: 0.877).Morphologic analysis of the thoracolumbar junction may help accurate spinal enumeration.Consideration of various variants at the thoracolumbar junction should help radiologists and clinicians to interpret the morphology of the thoracolumbar junction. This may facilitate communication with the referring clinician, thereby reducing the error in spinal enumeration.

Magnetic pulsed compaction (MPC) was introduced to consolidate conventional iron-based powders for the production of high-density steel parts in powder metallurgical (PM) processing. Highly dense steel components of Fe–1.5Cr–0.2Mo–0.25 C (wt.%) were obtained with green and sintered densities of 7.63 g/cm 3 and 7.75 g/cm 3 (full density: 7.8 g/cm 3 ). This anomalous densification in the MPC process was attributed to the complementary kinetic effect by the high impact pressure in a very short duration, allowing the enhanced particle rearrangement and plastic deformation in the compacted powders. Owing to this superior compactability, the intact compacts were fabricated efficiently even with the small addition of lubricant (less than 0.05 wt.%). Also, die wall lubrication was effective for preventing surface damage as well as for promoting homogeneous densification during the MPC. These results show a potential for application of the MPC process to high-density steel PM parts.

Objective To assess the attitudes of Korean physicians toward hormone therapy (HT) after publication of the Women's Health Initiative (WHI) study. Design Self-administered questionnaires, consisting of 22 items, were sent by mail to the members of the Korean Society of Menopause. Results More than 95% of Korean physicians were aware of the WHI study. The HT prescription rate decreased by 16% after publication of the WHI report; approximately half of the physicians who continued prescribing HT changed their prescriptions. The largest decreases occurred in regimens using conjugated equine estrogens and medroxyprogesterone acetate, for which prescriptions of sequential and continuous-combined regimens decreased by 20.7% and 22.7%, respectively. In contrast, the prescription rate for tibolone increased by 3.6%. Approximately 30% of physicians changed from standard to low doses, and 67.8% shortened the duration of HT. After publication of the WHI report, the main reasons for not prescribing or discontinuing HT were patient refusal and increased risk of cardiovascular disease, rather than breast cancer risk. After publication of the WHI report, the number of physicians who prescribed alternative or complementary medicines increased, the rate of HT prescription for the prevention of osteoporosis decreased, and the number of postmenopausal outpatients decreased. Conclusions Despite the results of the WHI report, most Korean physicians who participated in this study continued prescribing HT; however, approximately half of those who continued prescribing HT changed their prescriptions. The greatest change occurred in regimens using conjugated equine estrogens and medroxyprogesterone acetate.

Fusarium oxysporum Schlectend. Fr. f. sp. phaseoli J.B. Kendrick and W.C. Snyder (FOP) is a vascular pathogen that causes Fusarium wilt in common bean (Phaseolus vulgaris L.). This disease is an increasing problem in the western U.S., and exploitation of genetic resistance is considered the most feasible control method. The objective of this study was to detect quantitative trait loci (QTL) for Fusarium wilt resistance in a population derived from an interracial cross between FOP-susceptible Belneb RR-1 (race Durango) x FOP-resistant A55 (race Mesoamerica). Seventy-six [F.sub.6]-derived recombinant inbred lines (RILs) were screened for disease severity in greenhouse inoculations and rated on a scale of 1 (resistant) to 9 (susceptible). The phenotypic data were compared to existing random amplified polymorphic DNA (RAPD) marker data using single-factor analysis of variance. Marker U20.750 on linkage group (LG) 10 accounted for 63.5% of the phenotypic variance for this trait. Lines exhibiting the A55 banding pattern at this locus had disease severity scores that averaged 3.6 points lower than lines with the Belneb RR-1 pattern. Two additional markers, AD4.450 on LG 3 and K10.700 on LG 11, were significant (P [is less than] 0.01) in single-factor analysis of variance, but only marker U20.750 on LG 10 remained significant when composite interval mapping (CIM) was conducted. The tight linkage between the putative QTL and U20.750, as indicated by CIM, makes this marker a promising candidate for conversion to a sequence-characterized amplified region (SCAR) for use in marker-assisted selection in Fusarium wilt resistant common bean cultivar development., FUSARIUM WILT is a vascular disease of common bean. This fungus has been detected in bean-growing regions throughout the world, and is an economically significant problem in Latin America, Africa, [...]

A radio frequency (RF) plasma source operates by feeding helium or argon gas through two coaxial electrodes driven by a 13.56 MHz RF source. In order to prevent an arc discharge, a dielectric material is loaded outside the center electrode. A stable, arc-free discharge is produced at a flow rate of 1.5 l/min of helium gas. The temperature of the gas flame varies from 100 to 150 °C depending on the RF power. The breakdown voltage also changes when the flow rate varies. The plasma generation in a hot chamber is much more efficient than that in a cold chamber. The plasma characteristics are diagnosed by using optical emission spectroscopy. One of the applications of the RF plasma source is the printed circuit board (PCB) cleaning process, needed for environmental protection. The PCB cleaning device forms an asymmetric biaxial reactor.

Common bacterial blight (CBB), incited by the bacterial pathogen Xanthomonas campestris pv. phaseoli (Smith) Dye (Xcp) is a major problem in bean (Phaseolus vulgaris L.) producing areas worldwide. Using 128 recombinant inbred (RI) lines derived from the common bean cross BAC 6 x HT 7719, RAPD marker locus-QTL associations were previously described for resistance to two Xcp strains, EK-11 and Epif-IV. The objective of this research was to test these candidate marker locus-QTL associations in three previously untested genetic populations. In addition, RAPD marker locus-QTL associations were also investigated for resistance to a third Xcp strain, DR-7, in the first trifoliolate leaves in the original BAC 6 x HT 7719 population. The three genomic regions most significantly associated with CBB resistance in the original BAC 6 x HT 7719 population were significantly associated with CBB resistance in at least two of the three additional populations. The unmapped marker, BC409.1250, was significantly associated with CBB resistance in all four populations and all three Xcp strains, suggesting that this marker might be tightly linked to genes for CBB resistance. The RAPD marker BC409.1250 was converted into a marker that is a robust and reliable PCR-based marker. Since similar genomic regions were found for resistance to three different Xcp strains, these QTL may be useful for breeding cultivars with a broad range of resistance., COMMON BACTERIAL BLIGHT is a major constraint to the production of common bean worldwide (Saettler, 1989). Because of the lack of effectiveness of chemical applications, breeding for resistant cultivars is [...]

A soft switched space vector PWM inverter is developed using new parallel resonant DC-link (PRDCL). This PRDCL can operate on variable DC-link pulse position and width resulting in enhanced PWM capability, which is superior to other resonant DC-links. A new space vector algorithm is presented suitable for this PRDCL inverter. The suggested algorithm is able to eliminate narrow PWM pulses that impede DC-link operation. This PWM control, however, requires complex and precise timing sequences in relation to PRDCL operation, which is nicely solved by adopting a new programmed controller with a buffer and a programmable timer.

A soft-switched matrix converter is proposed using the zero voltage switching technique in some resonant pole inverters. A high operating frequency with safe and efficient switching improves the dynamic and spectral performances and simplifies the protection logics and snubber networks. Further, it can be implemented using simple analogue circuits, having similar transfer characteristics to those of the modern pulse width modulated matrix converters, such as maximum voltage transfer ratio and unity input displacement factor. Analyses, design and simulation results are presented to verify the operating principle.

A novel zero voltage switching (ZVS) voltage source inverter is presented to overcome the main problems of the resonant DC link type inverter with discrete pulse modulation, such as the subharmonic problem and high voltage stress (1.3 approximately 1.8 p.u.). The proposed ZVS inverter adopts a parallel resonant DC link and has pulsewidth modulation capability with minimum device voltage stress (1.0 p.u.). In addition, the design and control of the proposed inverter are fairly simple. The operational principle, a detailed analysis, and design procedures are described. A 7.5 kVA prototype inverter was implemented and tested with 20 kHz switching frequency. Experimental results verifying the principle of operation are shown. >

Between 1995 and 1997, 1,675 HIV-positive men and women using complementary and alternative medicine (CAM) were enrolled into the Bastyr University AIDS Research Center's Alternative Medicine Care Outcomes in AIDS (AMCOA) study. Funded by the National Institutes of Health (NIH) Office of Alternative Medicine (OAM) and National Institute of Allergy and Infectious Diseases (NIAID), the AMCOA study collected information on participant demographics, health status and use of conventional and CAM therapies. Participants from 46 states completed a baseline questionnaire, while additional clinical information (such as CD4 count and HIV-RNA viral load) was obtained from laboratory records. AMCOA participants reported using more than 1,600 different types of CAM therapies (1,210 CAM substances, 282 CAM therapeutic activities and 119 CAM provider types) for treating HIV/AIDS. Approximately two-thirds (63% n = 1,054) of the AMCOA cohort reported using antiretroviral drug therapy (ART) during the six-months previous to completing the baseline questionnaire, while 37% (n = 621) indicated they were not using ART. Of those not using ART, 104 subjects reported never having used any conventional medications for their HIV and 12 subjects used only non-prescription diarrhoea medications. The most frequently reported CAM substances were vitamin C (63%), multiple vitamin and mineral supplements (54%), vitamin E (53%) and garlic (53%). CAM provider types most commonly consulted by the AMCOA cohort were massage therapists (49%), acupuncturists (45%), nutritionists (37%) and psychotherapists (35%). CAM activities most commonly used were aerobic exercise (63%), prayer (58%), massage (53%) and meditation (46%). The choice of CAM therapies among the AMCOA cohort does not appear to be solely based on scientific evidence of efficacy of individual therapies. The majority of AMCOA subjects could be characterized as using integrated medicine, since an overwhelming proportion of the cohort consult with both conventional and CAM providers and use both conventional and CAM medications, yet few subjects reported that their conventional and CAM providers work as a team. These data and this cohort set the stage for conducting studies of health status changes associated with specific CAM therapies.

Purpose : Our goal was to evaluate CT findings of tuberculous abscess in the retromammary region of the breast. Method : Four patients with tuberculosis extending from the retromammary region to the pleura were examined by CT and the findings were evaluated. All cases were also examined with mammography and two cases were evaluated with sonography. Diagnosis was confirmed by acid-fast bacillus stain, culture, and histologic examination. Results : Mammography showed relatively smoothly marginated, round mass density in two cases, nodular density in one, and focal bulging of the pectoral wall in one. A sonogram demonstrated in two cases a fistulous connection from the heterogeneous, fluid-containing lesion with floating internal debris in the retromammary region to the thoracic cavity. In all four cases, CT showed relatively smoothly marginated, inhomogeneous, hypodense lesions with surrounding rims of the cold abscess type. A direct fistulous connection from the retromammary lesion through the thoracic wall into the pleura was seen in two cases. Destroyed rib fragments within the abscess were noted in two cases. Conclusion : A tuberculous abscess in the retromammary region usually showed on CT a focal, smoothly marginated, inhomogeneous, hypodense lesion with a surrounding enhancing rim. A direct fistulous connection with the pleura or a destroyed rib fragment in the abscess as revealed by CT can be helpful in the differential diagnosis of other infectious types of retromammary abscess.

We present a new analytical model of amorphous silicon thin-film transistor (a-Si TFT) suitable for circuit simulators such as SPICE. The effects of localized gap state distributions of a-Si as well as temperatures on the a-Si TFT performances have been fully considered in the presented model. The parameters used in SPICE, such as transconductance, channel-length modulation, and power factor of source-drain current, are evaluated from the measured current-voltage and capacitance-voltage characteristics by employing the proposed extraction method. It has been found out that the analytical model is in good agreement with experimental data at both room temperature and elevated temperature and successfully implemented in a widely used circuit simulator.

Alectinib, a highly selective inhibitor of anaplastic lymphoma kinase (ALK), has shown systemic and central nervous system (CNS) efficacy in the treatment of ALK-positive non-small-cell lung cancer (NSCLC). We investigated alectinib as compared with crizotinib in patients with previously untreated, advanced ALK-positive NSCLC, including those with asymptomatic CNS disease. In a randomized, open-label, phase 3 trial, we randomly assigned 303 patients with previously untreated, advanced ALK-positive NSCLC to receive either alectinib (600 mg twice daily) or crizotinib (250 mg twice daily). The primary end point was investigator-assessed progression-free survival. Secondary end points were independent review committee-assessed progression-free survival, time to CNS progression, objective response rate, and overall survival. During a median follow-up of 17.6 months (crizotinib) and 18.6 months (alectinib), an event of disease progression or death occurred in 62 of 152 patients (41%) in the alectinib group and 102 of 151 patients (68%) in the crizotinib group. The rate of investigator-assessed progression-free survival was significantly higher with alectinib than with crizotinib (12-month event-free survival rate, 68.4% [95% confidence interval (CI), 61.0 to 75.9] with alectinib vs. 48.7% [95% CI, 40.4 to 56.9] with crizotinib; hazard ratio for disease progression or death, 0.47 [95% CI, 0.34 to 0.65]; P

The purpose of this phase III clinical trial was to compare two different extracellular contrast agents, 1.0 M gadobutrol and 0.5 M gadopentate dimeglumine, for magnetic resonance imaging (MRI) in patients with known or suspected focal renal lesions. Using a multicenter, single-blind, interindividual, randomized study design, both contrast agents were compared in a total of 471 patients regarding their diagnostic accuracy, sensitivity, and specificity to correctly classify focal lesions of the kidney. To test for noninferiority the diagnostic accuracy rates for both contrast agents were compared with CT results based on a blinded reading. The average diagnostic accuracy across the three blinded readers ('average reader') was 83.7% for gadobutrol and 87.3% for gadopentate dimeglumine. The increase in accuracy from precontrast to combined precontrast and postcontrast MRI was 8.0% for gadobutrol and 6.9% for gadopentate dimeglumine. Sensitivity of the average reader was 85.2% for gadobutrol and 88.7% for gadopentate dimeglumine. Specificity of the average reader was 82.1% for gadobutrol and 86.1% for gadopentate dimeglumine. In conclusion, this study documents evidence for the noninferiority of a single i.v. bolus injection of 1.0 M gadobutrol compared with 0.5 M gadopentate dimeglumine in the diagnostic assessment of renal lesions with CE-MRI.
