Human papillomavirus (HPV) genotyping by HPV DNA chip in cervical cancer and precancerous lesions.

OBJECTIVES The human papillomavirus (HPV) is a well-known cause of cervical cancer. HPV tests are used as an adjunct test to decrease the false-negative rate of cytological screening. However, attempts are being made to replace the cytological screening with HPV tests. Therefore, this study was performed to examine the possibility of using HPV tests as screening test. MATERIALS AND METHODS The results of the tests that were performed at the same time including the ThinPrep cytology, the high-risk group hybrid capture II (HC-II) test, the HPV DNA chip (HD-C) test, and a punch biopsy were compared in 400 women who were referred to us due to abnormal cytology or cervicogram. The accuracy of each test was then evaluated, and the type of virus was investigated using a HD-C test. RESULTS The positive predictive values detected by the high-risk group HC-II test and HD-C test according to the histological diagnosis outcomes were 56.8 and 53.8%, respectively, for cervicitis; 91.5 and 91.5%, respectively, for cervical intraepithelial neoplasia I (CIN I); 88.1% and 81.0%, respectively, for CIN II; 88.6 and 84.2%, respectively, for CIN III, and 92.5 and 88.7%, respectively, for cancer (in 53 patients). The most prevalent types of HPV according to the HPV tests were types 16, 58, 18, and 52 in which type 16 was detected in the more advanced lesions. The sensitivity was 88.4% for the ThinPrep cytology, 89.9% for the HC-II for the high-risk group, and 86.2% for the HD-C test. CONCLUSION These results suggest the possibility of using the HC-II and HD-C tests as screening tests, which have a similar sensitivity as the ThinPrep cytology. Nonetheless, randomized controlled trials will be needed before the actual application of the HPV tests as screening tests. Despite the fact that the importance of HPV type 16 in cancer development was confirmed, the prevalence of types 58 and 52 were relatively high compared with those found in other studies, showing a need for further studies on this subject. These HPV types need to be considered in vaccine development.
Wage Inequality, Skills and Mastering New Technologies

In this paper I provide a new explanation for the increasing inequality between skilled and unskilled. This work introduces a problem solving based model in which agents invest in technological innovations to solve problems and sell their solutions in the market. Each agent has feasible set they can solve which depends on their skills and the set of technology they have access to. However, unlike the skilled biased technological change explanation, I do not assume that new technologies are necessarily complementary with skills. Instead, skills will play a role in how fast agents are able to adopt new technologies. High skilled individuals will adopt new technologies a lower cost relative to the unskilled. Under this frame, the model sets two different mechanisms that feed the wage gap between skilled and unskilled: productivity and access to the latest technological innovations.
Rational Inattention, Competitive Supply, and Psychometrics

We introduce a simple method of recovering attention costs from choice data. Our method rests on a precise analogy with production theory. Costs of attention determine consumer demand and consumer welfare just as a competitive firm's technology determines its supply curve and profits. We implement our recovery method experimentally, outline applications, and link our work to the broader literature on inattention and mistaken decisions.
Antibiotic treatment of children with sore throat.

CONTEXT Of children with sore throat, 15% to 36% have pharyngitis caused by group A beta-hemolytic streptococci (GABHS). Performance of a GABHS test prior to antibiotic prescribing is recommended for children with sore throat. Penicillin, amoxicillin, erythromycin, and first-generation cephalosporins are the recommended antibiotics for treatment of sore throat due to GABHS. OBJECTIVES To measure rates of antibiotic prescribing and GABHS testing and to evaluate the association between testing and antibiotic treatment for children with sore throat. DESIGN, SETTING, AND PARTICIPANTS Analysis of visits by children aged 3 to 17 years with sore throat to office-based physicians, hospital outpatient departments, and emergency departments in the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey, 1995 to 2003 (N = 4158) and of a subset of visits with GABHS testing data (n = 2797). MAIN OUTCOME MEASURES National rates of antibiotic prescribing, prescribing of antibiotics recommended and not recommended for GABHS, and GABHS testing. RESULTS Physicians prescribed antibiotics in 53% (95% confidence interval [CI], 49%-56%) of an estimated 7.3 million annual visits for sore throat and nonrecommended antibiotics to 27% (95% CI, 24%-31%) of children who received an antibiotic. Antibiotic prescribing decreased from 66% of visits in 1995 to 54% of visits in 2003 (P = .01 for trend). This decrease was attributable to a decrease in the prescribing of recommended antibiotics (49% to 38%; P = .002). Physicians performed a GABHS test in 53% (95% CI, 48%-57%) of visits and in 51% (95% CI, 45%-57%) of visits at which an antibiotic was prescribed. GABHS testing was not associated with a lower antibiotic prescribing rate overall (48% tested vs 51% not tested; P = .40), but testing was associated with a lower antibiotic prescribing rate for children with diagnosis codes for pharyngitis, tonsillitis, and streptococcal sore throat (57% tested vs 73% not tested; P<.001). CONCLUSIONS Physicians prescribed antibiotics to 53% of children with sore throat, in excess of the maximum expected prevalence of GABHS. Although there was a decrease in the proportion of children receiving antibiotics between 1995 and 2003, this was due to decreased prescribing of agents recommended for GABHS. Although GABHS testing was associated with a lower rate of antibiotic prescribing for children with diagnosis codes of pharyngitis, tonsillitis, and streptococcal sore throat, GABHS testing was underused.
Use of Admission Troponin in Critically Ill Medical Patients

Serum troponin I (TnI) is a sensitive marker of cardiac injury. A relation between elevated TnI and mortality has been suggested. In this retrospective chart review of 221 patients admitted to the medical intensive care unit (MICU) during a 6-month period, the authors studied the use of admission TnI levels in predicting mortality in MICU-admitted patients. Data retrieved included demographics, admission diagnosis, troponin, electrocardiogram, Acute Physiology and Chronic Health Evaluation (APACHE) II score, echocardiogram, requirements for mechanical ventilation and vasopressor support, development of multiorgan failure, mortality, and discharge disposition. There were 132 patients for whom TnI level was sent within 24 hours of admission; these patients comprised the study group. The median age was 70 years; 59% were female. The mean APACHE II score was 22. Troponin I was positive in 31% of patients (median level, 0.4 Ug/L; range 0-358 Ug/L). The hospital mortality was 39%. Positive TnI showed a weak association with intensive care unit (ICU) mortality ( P = .049) but not with overall mortality. There was no significant correlation between admission TnI concentration and APACHE II score ( P = .33), administration of vasopressor medications ( P = .115), or development of multiorgan failure ( P = .64). The authors concluded that there is no benefit in obtaining a routine admission troponin level in MICU patients when an acute coronary event is not suspected.
Stochastic Stability Analysis for Continuous Time Fault Tolerant Control Systems

Active fault tolerant control systems are feedback control systems that reconfigure the control law in real time based on the response from an automatic failure detection and identification (FDI) scheme. The dynamic behavior of such systems is characterized by stochastic differential equations because of the random nature of the failure events and the FDI decisions. The stability analysis of these systems is addressed in this paper using stochastic Lyapunov functions and supermartingale theorems. Both exponential stability in the mean square and almost sure asymptotic stability in probability are addressed. In particular, for linear systems where the coefficients of the closed loop system dynamics are functions of two random processes with Markovian transition characteristics (one representing the random failures and the other representing the FDI decision behavior), necessary and sufficient conditions for exponential stability In the mean square are developed.
Validity and reliability of the Chronic Oral Mucosal Diseases Questionnaire in a UK population.

OBJECTIVE The objective of this study was to investigate the validity and reliability of a the Chronic Oral Mucosal Diseases Questionnaire in a UK population METHODS Two hundred patients with chronic oral mucosal disease (oral lichen planus, recurrent aphthous stomatitis, mucous membrane pemphigoid, pemphigus vulgaris) were enrolled in this study from the Oral Medicine Department of University College London Hospitals Trust (UCLHT) Eastman Dental Hospital. Individuals were interviewed using Oral Health Impact Profile (OHIP-14), Visual Analogue Scale (VAS) and Chronic Oral Mucosal Diseases Questionnaire (COMDQ), and the construct validity and internal reliability were examined. RESULTS Of the 200 study participants, 100 respondents had oral lichen planus, 42 had recurrent aphthous stomatitis and 58 had vesiculobullous conditions (mucous membrane pemphigoid or pemphigus vulgaris). With regard to construct validity, a moderate to good degree of convergent validity was found between OHIP-14 and VAS and most subscales and the total COMDQ score except the patient support subscale of COMDQ (0.21-0.37). CONCLUSION COMDQ is a valid and reliable patient-reported outcome measure for patients with chronic oral mucosal diseases in a UK population. It can be considered a valuable instrument in both clinical practice and in oral medicine research.
A Population-Based Case-Control Study on the Effect of Bronchial Asthma During Pregnancy for Congenital Abnormalities of the Offspring

Bronchial asthma is one of the most common maternal diseases complicating pregnancy. We assessed the risks of congenital abnormalities in a case-control population-based analysis using the dataset of the Hungarian Case-Control Surveillance of Congenital Abnormalities between 1980 and 1996. Of the 22,843 cases with congenital abnormalities, 511 (2.2%) had mothers with bronchial asthma, while of the 38,151 matched control subjects without congenital abnormalities 757 (2.0%) had mothers with bronchial asthma (unadjusted prevalence odds ratios [POR] 1.2; 95% CI: 1.0-1.3). In all mothers with bronchial asthma, a higher incidence of respiratory tract infections and higher drug intake could be observed. In the case group of medically recorded bronchial asthma, a slightly increased risk for club foot has been revealed. However, this weak association could be explained by the higher proportion of preterm births in this group. The main limitation of the analysis was that at the time of data collection only a small proportion of pregnant mothers were using anti-asthma medications recommended by the actual guidelines.
A Prospective Randomized Comparison of Patellar Tendon versus Semitendinosus and Gracilis Tendon Autografts for Anterior Cruciate Ligament Reconstruction *

Seventy patients with patellar tendon or hamstring tendon autografts for single-incision anterior cruciate ligament reconstruction were evaluated at least 2 years after surgery. All reconstructions were performed by the same surgeon, and metal interference screws were used for fixation of all grafts. No significant differences were noted between groups for Lysholm score, reduction in activity, KT-1000 arthrometer findings, quadriceps muscle size, return to sports, or ability to jump and do hard cuts and pivots. Significantly more patients in the patellar tendon group had patellofemoral pain at 6 months after surgery than did the hamstring tendon patients (48% versus 20%), and at last follow-up the incidence of patellofemoral pain was 42% and 20%, respectively. Fourteen patients in the patellar tendon group and seven in the hamstring tendon group had loss of motion (approximately 5°). Four patients (two in each group) had treatment failures and their results were not included in the clinical examination data. At 2 years’ follow-up, 97% of patients with patellar tendon grafts and 100% of patients with hamstring tendon grafts rated their results as good or excellent. We found that hamstring tendon grafts performed similarly to patellar tendon grafts, although fewer patients in the hamstring tendon group had patellofemoral pain and loss of motion.
A survey of communication skills training in UK Schools of Medicine: present practices and prospective proposals

It is now widely accepted that effective interpersonal communication is at the heart of quality health care delivery but that current standards in medicine must be improved ( Numann 1988 ; Cowan et al. 1992 ). One approach acknowledged by the General Medical Council (1991 ) devotes more attention during training to the theme of communication, and quite significant modifications of the undergraduate medical curriculum are presently taking place. This article documents the results of a postal survey of the 26 UK Schools of Medicine, designed to illuminate current practices and future plans in respect of communication skills training (CST). As such, it takes advantage of the present period of ongoing curricular innovation and change to extend and update earlier reviews ( Whitehouse 1991 ; Frederikson & Bull 1992 ). A total of 19 responses was received. Following preliminary analysis, the four schools who had already implemented their new curriculum were selected for further in‐depth investigation by means of telephone interviews. In addition to reporting frequencies and percentages for responses to questions, cross‐tabulations were carried out to explore relationships between certain of the findings. Apart from some consistency in CST teaching methods adopted, the overall picture to emerge is one of considerable variability in such areas as course content, timing, duration and assessment. Foremost among the difficulties encountered in implementing CST appeared to be lack of adequate physical resources and suitably trained staff. Future plans were often sketchy and inchoate. Results are discussed and tentative recommendations for the further development of CST in the medical curriculum proffered.
How Do Dual Long‐Acting Bronchodilators Prevent Exacerbations of Chronic Obstructive Pulmonary Disease?

&NA; Decreasing the frequency and severity of exacerbations is one of the main goals of treatment for patients with chronic obstructive pulmonary disease. Several studies have documented that long‐acting bronchodilators can reduce exacerbation rate and/or severity, and others have shown that combinations of long‐acting &bgr;2‐adrenergic agonists (LABAs) and long‐acting muscarinic antagonists (LAMAs) provide greater reductions in exacerbation frequency than either their monocomponents or LABA/inhaled corticosteroid combinations in patients at low and high risk for these events. In this review, small groups of experts critically evaluated mechanisms potentially responsible for the increased benefit of LABA/LAMA combinations over single long‐acting bronchodilators or LABA/inhaled corticosteroids in decreasing exacerbation. These included effects on lung hyperinflation and mechanical stress, inflammation, excessive mucus production with impaired mucociliary clearance, and symptom severity. The data assembled and analyzed by each group were reviewed by all authors and combined into this manuscript. Available clinical results support the possibility that effects of LABA/LAMA combinations on hyperinflation, mucociliary clearance, and symptom severity may all contribute to decreasing exacerbations. Although preclinical studies suggest LABAs and LAMAs have antiinflammatory effects, such effects have not been demonstrated yet in patients with chronic obstructive pulmonary disease.
Enhancing customer satisfaction through total quality management practices – an empirical examination

This paper attempts to develop a model which shows the relationship between TQM practices and customer satisfaction level particularly in Indian manufacturing context through an empirical approach. Though there is considerable literature available in this area to examine the impact of TQM practices on organisation performance across the globe, still little is known about the effect of TQM practices on firm’s performance in Indian organisations. To examine the linkage more closely, the relationship between individual TQM practices and customer satisfaction level as a performance indicator was investigated explicitly. The empirical data were collected from a survey of 260 Indian manufacturing organisations using a self-administrated questionnaire. The study has contributed a model of 10 TQM constructs. The data were analysed and hypotheses regarding individual TQM practices were tested using multiple regression. In addition to that, structural equation modelling was used to determine the relationship between TQM and customer satisfaction level. Overall, the findings indicated that there exists a positive and significant relationship between TQM practices and customer satisfaction level. The study also revealed that knowledge management and customer focus were perceived as the most dominant TQM practices associated with customer satisfaction.
Presentation and Management of Gastrointestinal Stromal Tumors of the Duodenum

Duodenal gastrointestinal stromal tumors (GIST) have been described primarily in isolated case reports. In order to learn more about duodenal GIST, a retrospective review of patients with GIST managed at a single institution between 2000 and 2005 was conducted. Thirty-eight GIST of the stomach and small bowel were analyzed. Eight (21%) were duodenal GIST. The median size of duodenal GIST (6.0 cm) and small bowel GIST (6.3 cm) was larger than the median size of gastric GIST (3.0 cm). The most common presentation of duodenal GIST was bleeding (50%) which was similar to other small bowel GIST (49%) but different from gastric GIST which were most commonly an incidental finding (62%). Two patients (25%) with duodenal GIST had a history of neurofibromatosis. The duodenal GIST were located in the 2nd (n = 5, 63%) and 3rd portion of duodenum (n = 3, 37%). Seven of 8 patients underwent complete resection of duodenal GIST. Pancreaticoduodenectomy was the most common operation performed (n = 5); 2 patients were treated with partial duodenal resection. No patients undergoing pancreaticoduodenectomy (n = 5) were found to have lymph node metastases. No patients received neo-adjuvant or adjuvant therapy with Imatinib. Following resection, 2 patients have recurred (12 and 48 mo.), 4 patients are without disease (1, 6, 6, and 24 mo.), 1 patient died postoperatively. Duodenal GIST are relatively rare tumors that present most commonly with gastrointestinal bleeding. Duodenal GIST are associated with neurofibromatosis. Many duodenal GIST require pancreaticoduodenectomy for complete removal.
Development and Evaluation of Innovative Peer-Led Physical Activity Programs for Mental Health Service Users

Abstract Mental health service users (MHSUs) have elevated rates of cardiometabolic disturbance. Improvements occur with physical activity (PA) programs. We report the development and evaluation of three innovative peer-developed and peer-led PA programs: 1) walking; 2) fitness; and 3) yoga. Qualitative evaluation with 33 MHSUs in British Columbia, Canada, occurred. These programs yielded improvements for participants, highlighted by powerful narratives of health improvement, and improved social connections. The feasibility and acceptability of innovative peer-developed and peer-led programs were shown. Analyses revealed concepts related to engagement and change. Relating core categories, we theorize effective engagement of MHSUs requires accessibility on three levels (geographic, cost, and program flexibility) and health behavior change occurs within co-constituent relationships (to self, to peers, and to the wider community). This study highlights the benefits of peer involvement in developing and implementing PA programs and provides a theoretical framework of understanding engagement and behavior change in health programs for MHSUs.
Relationships between fatty acid status of sow plasma and that of umbilical cord, plasma and tissues of newborn piglets when sows were fed on diets containing tuna oil or soyabean oil in late pregnancy

To investigate the relationships between maternal, umbilical cord and piglet fatty acid status, multiparous sows (six per diet) were fed on diets containing supplements (30 g/kg) of either soyabean oil or tuna oil for the last 21 d of pregnancy. The proportions of most fatty acids differed between diets: in particular, the tuna-oil-containing diet supplied more 22:6n-3 and less 18:2n-6 fatty acids than the soyabean-oil-containing diet. Maternal plasma fatty acid concentrations (mg/l) were greater than those in umbilical plasma and 20:4n-6 and 22:6n-3 fatty acids were present in higher proportions (g/100 g fatty acids) in umbilical than maternal plasma. Feeding tuna oil increased the proportionate amounts (g/100 g fatty acids) of total n-3 fatty acids (particularly 22:6n-3) in umbilical cord, plasma and piglet tissues compared with feeding soyabean oil: in contrast, the proportion of 20:4n-6 was decreased by feeding tuna oil. Changes in piglet fatty acid proportions as a result of oil feeding were not influenced by piglet weight. While proportions of the long-chain n-3 and n-6 polyunsaturated fatty acids in piglet liver, spleen and reproductive tract (ovaries plus uterus of the female, testes of the male) correlated well with those of umbilical plasma, those in brain and retina were poorly correlated. Therefore umbilical plasma cannot be used to predict the fatty acid status of piglet brain.
