Factors associated with the failure of HIV-positive persons to return for scheduled medical visits

Abstract PURPOSE: To assess in an HIV-positive cohort the cumulative probability of failing to return for scheduled medical visits and to address the factors associated with follow-up discontinuation. METHOD: This was a hospital-based cohort study conducted from January 1985 through September 1999. Out of 3,300 HIV-1 infected patients, 1,680 patients with CD4 count <500 cells/mL or with AIDS diagnosis were included in the analysis because they received scheduled medical visits for follow-up at our center. Baseline visit was the first visit when patients met the criteria for enrollment. The main outcome measure was failure to return for scheduled medical visits for at least 12 consecutive months. RESULTS: The probability of returning decreased rapidly in the first months after the baseline visit. After 1 year since enrollment, 25% of patients failed to return and after 2 years 34% of patients failed to return. Most patients who failed to return for visits (78%) discontinued their follow-up within 6 months since enrollment. In multivariate analysis, patients in the intravenous drug use (IDU) category were most likely to fail to return for scheduled appointments, as were patients with higher CD4 count (CD4 >50 cells/μL) or patients without AIDS diagnosis. Patients with shorter follow-up had a higher risk of failing to return (odds ratio [OR]: 0.12, 0.36, 0.45, and 0.74 for >36, 24-36, 12-24, and 6-12 months of follow-up respectively vs. <6 months). Patients who were enrolled in more recent years had a higher compliance to follow-up visits (OR: 0.33, 0.63, and 0.61 for ≥1997, 1995-1996, and 1988-1994 vs. <1988). CONCLUSION: Patients in the IDU category, patients without AIDS diagnosis, or patients with higher CD4 counts are more likely to miss medical appointments and discontinue their follow-up. More recently enrolled patients have a lower risk of failing to return. It is possible that the recent and more effective anti-HIV treatment played a major role in increasing adherence to follow-up.
Cancer Statistics, 2003

Each year, the American Cancer Society estimates the number of new cancer cases and deaths expected in the United States in the current year, and compiles the most recent data on cancer incidence, mortality, and survival by using incidence data from the National Cancer Institute (NCI) and mortality data from the National Center for Health Statistics (NCHS). Incidence and death rates are age adjusted to the 2000 US standard population. In the year 2003, we estimate that 1,334,100 new cases of cancer will be diagnosed, and 556,500 people will die from cancer in the United States. Age‐adjusted cancer death rates declined in both males and females in the 1990s, though the magnitude of decline is substantially higher in males than in females. In contrast, incidence rates continued to increase in females while stabilizing in males. African‐American males showed the largest decline for mortality. However, African Americans still carry the highest burden of cancer with diagnosis of cancer at a later stage and poorer survival within each stage compared with Whites. In spite of the continued decline in cancer death rates in the most recent time period, the total number of recorded cancer deaths in the United States continues to increase slightly due to the aging and expanding population.
Successes and failures of the k

The k\ensuremath{\cdot}p method combined with the envelope-function approximation is the tool most commonly used to predict electronic properties of semiconductor quantum wells and superlattices. We test this approach by comparing band energies, dispersion, and wave functions for GaAs/AlAs superlattices and quantum wells as computed directly from a pseudopotential band structure and using eight-band k\ensuremath{\cdot}p. To assure equivalent inputs, all parameters needed for the k\ensuremath{\cdot}p treatment are extracted from calculated bulk GaAs and AlAs pseudopotential band structures. Except for large exchange splittings in the in-plane dispersion for thin superlattices, present in pseudopotential calculations but absent from the k\ensuremath{\cdot}p results, we find generally good agreement for heterostructure hole bands within \ensuremath{\sim}200 meV of the GaAs valence-band maximum. There are systematic errors in band energies and dispersion for deeper hole bands (all other than hh1 and lh1) and significant qualitative and quantitative errors for the conduction bands. Errors for heterostructure conduction states which are derived from the zinc-blende \ensuremath{\Gamma} point diminish as length scales increase beyond \ensuremath{\sim}20 ML, while significant errors persist for L- and X-derived states.
Gene arrangements and phylogeny in the class Proteobacteria.

A simple method is presented for reconstructing phylogenetic trees on the basis of gene transposition. It is shown that differences in gene arrangements among genomes could allow us to determine whether a gene transposition event has occurred before or after species divergence from parsimonious considerations. The method is applied to evolutionary relationships among the bacterial class Proteobacteria, for which complete genomic sequences most densely accumulate and comprehensive gene order comparisons are possible. We were able to infer the emergence order of proteobacterial subclasses as epsilon-->beta-->gamma. This order is consistent with sequence-based inferences, which conversely confirms the usefulness of the approach presented here.
Intermediate frequency magnetic field at 23 kHz does not modify gene expression in human fetus‐derived astroglia cells

The increased use of induction heating (IH) cooktops in Japan and Europe has raised public concern on potential health effects of the magnetic fields generated by IH cooktops. In this study, we evaluated the effects of intermediate frequency (IF) magnetic fields generated by IH cooktops on gene expression profiles. Human fetus‐derived astroglia cells were exposed to magnetic fields at 23 kHz and 100 µTrms for 2, 4, and 6 h and gene expression profiles in cells were assessed using cDNA microarray. There were no detectable effects of the IF magnetic fields at 23 kHz on the gene expression profile, whereas the heat treatment at 43 °C for 2 h, as a positive control, affected gene expression including inducing heat shock proteins. Principal component analysis and hierarchical analysis showed that the gene profiles of IF‐exposed groups were similar to the sham‐exposed group and were different than the heat treatment group. These results demonstrated that exposure of human fetus‐derived astroglia cells to an IF magnetic field at 23 kHz and 100 µTrms for up to 6 h did not induce detectable changes in gene expression profile.

Thoracic discectomy by posterior pedicle-sparing, transfacet approach with real-time intraoperative ultrasonography: Clinical article.

OBJECT Symptomatic thoracic disc herniations (TDHs) are relatively uncommon, and the technical challenges of resecting the offending disc are formidable due to the location of spinal cord that has relatively poor perfusion characteristics within a narrow canal. The majority of disc herniations are long-standing calcified discs that can be adherent to the ventral dura. Real-time intraoperative ultrasound (RIOUS) visualization of the spinal cord during the retraction and resection of the disc greatly enhances the safety and efficacy of disc resection. The authors have adopted the posterior laminectomy with pedicle-sparing transfacet approach with real-time ultrasound guidance in their practice, and they present the clinical outcome in their patients to illustrate the safety profile of this technique. METHODS Sixteen consecutive patients undergoing operative management of TDHs were identified from the authors' database. All patients underwent microdiscectomy through a posterior transfacet pedicle-sparing approach under RIOUS. Outcomes and complications were retrospectively assessed in this patient series. Clinical records and pre- and postoperative imaging studies were scrutinized to assess levels and types of disc herniation, blood loss, surgical time, pre- and postoperative Nurick grades, Japanese Orthopaedic Association (JOA) scores, and complications. RESULTS All patients had single-level symptomatic TDHs. The patients presented with symptoms including thoracic myelopathy, axial back pain, urinary symptoms, and thoracic radiculopathy. Thoracic disc herniations involved levels T2-3 to T12-L1. Discs were classified as central or paracentral, and as calcified or noncalcified. All discs were successfully removed with no incidence of neural injury or CSF leak. The mean estimated blood loss was 523 ml, and the mean surgical time was 159 minutes. Nurick grades improved on average from 3.3 to 1.6. The mean JOA scores improved from 5.7 to 8.3 out of 11. The mean Hirabayashi recovery rate of the JOA score was 57%. All patients reported improvement in symptoms compared with preoperative status except for 1 patient with an American Spinal Injury Association Grade A spinal cord injury prior to surgery. The average duration of follow-up was 10.5 months. One patient developed postoperative wound infection that required additional operative debridement and revision of hardware. CONCLUSIONS Thoracic discectomy via a posterior pedicle-sparing transfacet approach is an adequate method of managing herniations at any thoracic level. The safety of the operation is significantly enhanced by the use of realtime intraoperative ultrasonography.
Malachi 4:4-6 (Heb 3:22-24) as a point of convergence in the Old Testament or Hebrew Bible: a consideration of the intra and intertextual relationships

Malachi 4:4−6 (Heb 3:22−24) occupies a special place in the canon of Scriptures. In Malachi 4:4−6 (Heb 3:22−24) not only the book of Malachi comes to a close but the whole of the Prophets (Nebi’im), and the second part of the Hebrew Bible. In the Christian Bible the book of Malachi is the last book in the Old Testament, which is concluded with this passage, before one turns to the New Testament. In this article it was argued the these three verses serve not only as the conclusion to the book of Malachi but also as a fitting close to the second part of the Hebrew Bible. It also serves as a link to both the Pentateuch as the first part, and the Psalms as the third part, of the Hebrew canon of Scriptures. In this sense Malachi 4:4−6 (Heb 3:22−24) can be viewed as a point of convergence in the Old Testament or Hebrew Bible.
10-GHz train of sub-500-fs optical soliton-like pulses from a surface-emitting semiconductor laser

We report sub-500-fs operation of a passively mode-locked diode-pumped external-cavity surface-emitting semiconductor laser at a repetition rate of 10.014 GHz. For an incident pump power of 706 mW, the laser produced 486-fs soliton-like pulses, with an average output power of 30.3 mW. The role of the ac Stark effect in shaping subpicosecond pulses is demonstrated.
FACE RECOGNITION USING SEMI DISCRETE DECOMPOSITION AND FLDA FOR SINGLE TRAINING IMAGE PER PERSON

PCA and FLDA are mainly used in face recognition and feature extraction. PCA uses eigen vector and FLDA uses within class scatter matrix and between class scatter matrix. When within class matrix becomes singular, it cannot be evaluated. A new method called semi-discrete decomposition is used in single image per person problems. The performance of this method is tested on 4-data bases, namely ORL, UMIST, Poly u-NIR, YALE. The proposed method performs better than SVD based approach and QRCP based approach in terms of recognition rate with training times in two times higher than QRCP.
Hepatitis B virus with a proposed genotype I was found in Sichuan Province, China

To date, eight hepatitis B virus (HBV) genotypes, A–H, have been designated, and two additional genotypes, I and J, have also been proposed. A serological survey targeting children in difficult‐to‐reach vaccination areas was carried out in remote counties of Sichuan Province, China. HBV genotypes and serotypes were also determined from HBsAg‐positive serum samples by direct sequencing. Phylogenetic analysis showed two strains isolated from the Yi ethnic children clustered with the proposed genotype I. The pairwise genome genetic distance was 7.5% between genotypes I and C, and ranged from 8.4% to 15.2% between genotype I and other genotypes, except genotype C. Grouping Scan analyses of the two strains revealed apparent recombination events between an unknown genotype and genotype C. Two out of four HBV strains isolated from the Yi ethnic children were confirmed to be genotype I, suggesting widespread circulation and common infection with genotype I HBV in the local Yi population. High prevalence of HBsAg and low hepatitis B vaccination coverage indicated that additional efforts are needed to control HBV infection in those areas. J. Med.

Analyse des effets directs de rayonnements ionisants à différents TELs dans un modèle expérimental in vitro de cartilage humain sain et pathologique

L’hadrontherapie par ions carbone represente une modalite de radiotherapie alternative tres attractive du fait des proprietes physiques et biologiques de ce type de particules. Les chondrosarcomes, tumeurs radio-resistantes a differentiation cartilagineuse, sont en premiere ligne pour le traitement par ions carbone. Cependant, les effets secondaires sur les tissus sains environnants sont peu ou mal connus. Ce projet a pour but l’etude des effets directs des ions acceleres dans un modele 3D de cartilage sain et pathologique proche de l’homeostasie humaine et le developpement de nouveaux outils de calculs d’efficacite biologique relative (EBR). Dans un premier temps, nous nous sommes interesses aux sequelles radio-induites sur le cartilage articulaire dans un contexte d’hadrontherapie par ions carbone. En culture 2D physioxique (2% d’O2), l’efficacite biologique relative des ions carbone (transfert d’energie lineique ou TEL intermediaire) comparee aux rayons X a ete evaluee a 2,6. Ceci a ete correle a une plus forte induction de senescence radio-induite. Cependant, cet effet differentiel n’a pas ete retrouve en utilisant un modele 3D de cartilage articulaire. L’efficacite biologique relative des ions acceleres semble donc surevaluee, en utilisant des cultures en monocouche, par rapport a la 3D. Dans un deuxieme temps, un modele 3D de chondrosarcome a ete developpe pour des etudes d’hadronbiologie. Apres plusieurs obstacles techniques, des methodes d’extraction proteique et d’immunohistochimie ont ete mises au point. Une nouvelle methode d’evaluation de l’EBR en 3D basee sur la cinetique d’induction de la proteine γ-H2AX a ete proposee.
Social Affinity and Facial Emotion Based Social Correlation

In recent years the social network analysis has been increased, in this paper we focus mining the small network formed by social gathering or business meeting. The main objective is to discover the existence of correlation and influence among the group of people by analysing their social affinity and emotions, currently we are interested only in facial emotions. Whereas the approach for emotion detection lies in the dynamic and probabilistic framework of deep belief networks and active appearance model. Combining active appearance model with deep belief networks for emotion recognition gives higher recognition performance level compared with other methods. In order to evaluate our system, we carried out a discussion in our laboratory, and based on its ground truth observed we validate the proposed algorithm. Finding such correlations to locate influential persons could be used for viral marketing, understanding grouping and leadership, consensus building, etc.
Pediatric Solid Pseudopapillary Neoplasm[Spn] of The Pancreas : Case Report and Literature Review

Background: Pediatric pancreatic malignancies are extremely rare with an age population-adjusted incidence of 0.018 cases per 100,000. In adolescent girls, they usually present as solid pseudopapillary neoplasms[SPNs], low-grade malignant tumors of the exocrine pancreas. Due to their rarity and nonspecific clinical presentation, SPNs are frequently misdiagnosed. The treatment of choice is a complete surgical resection with 5-year survival rate of 97%. Case Report: We report a 17-year-old girl with SPN presenting with jaundice and itchy skin. She was initially misdiagnosed with hepatoblastoma, and treated with neoadjuvant chemotherapy. The girl later underwent surgical excision, and is in complete remission seven years after the diagnosis. Conclusion: Although rare, SPNs need to be included in the differential diagnosis of abdominal masses in children. MRI detected, well-defined, encapsulated, heterogeneous mass, especially in adolescent females, should always be suspicious for SPN. Further prospective multi-institutional studies are required in order to standardize preoperative evaluation and reduce the high misdiagnosis rate.
Delay-Dependent ${H}_{\infty}$  Filtering of Piecewise-Linear Systems With Time-Varying Delays

This paper investigates Hinfin filtering design problems for discrete time piecewise-linear systems with constant or time-varying delays. Firstly, a novel delay-dependent piecewise Lyapunov-Krasovskii functional (LKF) is proposed, in which both the upper and the lower bound of delays are considered. Then, based on this piecewise LKF, the delay-dependent stability criteria of systems with constant or time-varying delays are obtained, respectively, and piecewise Hinfin filtering design approaches are proposed. It is shown that our stability analysis is less conservative and the corresponding Hinfin filtering can achieve better performance. The filtering parameters can be obtained by solving a set of linear matrix inequalities (LMIs). Simulation examples are also given to illustrate the performance of the proposed approaches.
A static technique for fault localization using character n-gram based information retrieval model

Bug or Fault localization is a process of identifying the specific location(s) or region(s) of source code (at various granularity levels such as the directory path, file, method or statement) that is faulty and needs to be modified to repair the defect. Fault localization is a routine task in software maintenance (corrective maintenance). Due to the increasing size and complexity of current software applications, automated solutions for fault localization can significantly reduce human effort and software maintenance cost. We present a technique (which falls into the class of static techniques for bug localization) for fault localization based on a character n-gram based Information Retrieval (IR) model. We frame the problem of bug localization as a relevant document(s) search task for a given query and investigate the application of character-level n-gram based textual features derived from bug reports and source-code file attributes. We implement the proposed IR model and evaluate its performance on dataset downloaded from two popular open-source projects (JBoss and Apache). We conduct a series of experiments to validate our hypothesis and present evidences to demonstrate that the proposed approach is effective. The accuracy of the proposed approach is measured in terms of the standard and commonly used SCORE and MAP (Mean Average Precision) metrics for the task of fault localization. Experimental results reveal that the median value for the SCORE metric for JBoss and Apache dataset is 99.03% and 93.70% respectively. We observe that for 16.16% of the bug reports in the JBoss dataset and for 10.67% of the bug reports in the Apache dataset, the average precision value (computed at all recall levels) is between 0.9 and 1.0.
Scavenger activity of Allium psekemense B. Fedtsch

In the present study the antioxidative properties of the bulbs, leaves and stalks of Allium psekemense B. Fedtsch were investigated. The activities of antioxidant enzymes (superoxide dismutase, catalase, peroxidase, glutathione peroxidase), quantities of malonyldialdehyde, superoxide and hydroxyl radicals and reduced glutathione and also the content of total flavonoids, chlorophylls a and b, carotenoids, vitamin C and soluble proteins were determined. The results indicate that extracts from all plant organs exhibited antioxidant activity. The highest antioxidant activity was observed in the leaves. Furthermore, the ESR signal of DMPO‐OH radical adducts in the presence of the leaf phosphate buffer (pH 7) extract was reduced by 54.3%. Copyright © 2002 John Wiley & Sons, Ltd.
What does your purity matter to me ? ”

The results of four studies suggest that contamination concerns involved in prejudice towards male homosexuals may be expressed in the increased need for physical cleansing after an imagined contact with a homosexual man. Participants in Study 1 completed word fragments according to the theme of cleansing, and in Study 2, they chose a cleansing wipe more often after imagining using the mobile of a homosexual (vs. heterosexual) man. The need for cleansing was specific to the body parts engaged in the contact. In Study 3, participants evaluated hand and mouth cleansing products as more desirable after imagining using a mobile phone of a homosexual (vs. heterosexual) man. The specific need for cleansing, but not the accessibility of cleansing related words, was more pronounced among political conservatives (Study 4). The results are discussed with reference to the behavioral immune system hypothesis, research on moral disgust, and the embodiment literature.
A novel human immunodeficiency virus type 1 protein, tev, shares sequences with tat, env, and rev proteins

We have characterized a novel 28-kilodalton protein, p28tev, detected in human immunodeficiency virus type 1-infected cells. tev is recognized by both tat and rev monospecific antibodies. tev is initiated at the tat AUG and contains the first exon of tat at its amino terminus, a small portion of env in the middle, and the second exon of rev at its carboxy terminus. A cDNA clone producing tev was cloned and expressed in human cells. Sequence analysis revealed that the tev mRNA is generated by splicing to a novel exon located in the env region. This identifies a fourth class of multiply spliced human immunodeficiency virus mRNAs, produced in infected and transfected cells. tev is regulated during the virus life cycle similarly to the other regulatory proteins, tat, rev, and nef, and displays both tat and rev activities in functional assays. Since tev contains important functional domains of tat and rev and is produced very early after transfection, it may be an important regulator in the initial phase of virus expression. Another rev-related protein, p18(6)Drev, containing env and rev sequences, was characterized and was found not to have detectable rev activity.
Quantification of myocardial blood flow using non–electrocardiogram‐triggered MRI with three‐slice coverage

Accurate quantification of myocardial perfusion is dependent on reliable electrocardiogram (ECG) triggering. Measuring myocardial blood flow (MBF) in patients with arrhythmias or poor ECGs is currently infeasible with MR. The purpose of this study was to demonstrate the feasibility of a non–ECG‐triggered method with clinically useful three‐slice ventricular coverage for measurement of MBF in healthy volunteers.
