Postthrombotic syndrome after hip or knee arthroplasty: a cross-sectional study.

BACKGROUND
Although the incidence of the postthrombotic syndrome (PTS) has been addressed in patients with symptomatic deep vein thrombosis (DVT), less information is available on the incidence in patients who develop asymptomatic DVT after major hip or knee arthroplasty.


OBJECTIVES
To determine whether symptomatic PTS occurs more frequently in patients who develop DVT after hip or knee arthroplasty than those who are free of DVT and to provide an estimate of the incidence of PTS in patients who had undergone major hip or knee arthroplasty and had proximal DVT, distal (calf) DVT, or no DVT.


DESIGN AND SETTING
A cross-sectional study conducted at the Hamilton Health Sciences Corporation, Hamilton, Ontario, and the Academic Medical Centre, Amsterdam, the Netherlands.


SUBJECTS AND METHODS
Two hundred fifty-five subjects who had undergone major hip or knee arthroplasty 2 to 7 years previously and had routine predischarge venography showing proximal DVT (n = 25), distal DVT (n = 66), or no DVT (n = 164) were enrolled from March 1993 through December 1998. The presence of symptomatic PTS confirmed by the presence of objectively confirmed venous valvular incompetence was ascertained.


RESULTS
The rates of PTS were low and not significantly different among the 3 subgroups: 1 (4.0%, 95% confidence interval [CI] = 0.1%-20.4%) of 25 patients with proximal DVT, 4 (6.1%, 95% CI = 1.7%-14.8%) of 66 patients with distal DVT, and 7 (4.3%, 95% CI = 1.7%-8.6%) of 164 patients with no DVT.


CONCLUSIONS
Symptomatic PTS is an uncommon complaint after major hip or knee arthroplasty. Patients who develop postoperative proximal or distal DVT and who receive 6 to 12 weeks of anticoagulant therapy are not predisposed to PTS.
Bodyweight and carcass characteristics of somali goats fed hay supplemented with graded levels of peanut cake and wheat bran mixture

The experiment was conducted for ninety days of feeding trial at Haramaya University, Ethiopia using twenty four yearling male Somali goats weighing 20.4 ± 2.02 (mean ± SD) with the objectives to evaluate the effect of supplementation of peanut cake and wheat bran mixture (3:1) on body weight (BW) gain and carcass characteristics of Somali goats. The experiment was arranged with six blocks and four treatments in a randomized complete block design. The treatments were ad libitum feeding of hay (T1, control) and supplementation with 200 g (T2), 300 g (T3) and 400 g (T4) peanut cake and wheat bran mixture on dry matter (DM) basis. Supplementation reduced (P < 0.001) hay DM intake, but increased (P < 0.001) total DM intake at 300 g DM (T3) and 400 g DM (T4) level of supplementation compared to the control treatment. Daily BW gain, final BW, empty BW, hot carcass weight and dressing percent were higher (P < 0.001) in the supplemented treatments. Goats on the medium (T3) level of supplementation had significantly heavier (P < 0.001) liver and more muscle deposition, whereas those on hay alone (T1) exhibited heavier bone, head as well as gut contents (P < 0.05). It was concluded that supplementation of Somali goats with the different levels of peanut cake and wheat bran mixture promoted BW gain, dressing percentage and increased the proportion of edible offals. Similarity between the different levels of supplementation used in this study with regard to BW and carcass characteristics favours the use of the low (T2) or medium (T3) level than the high (T4) level of supplementation.
Leadership styles and organizational commitment: literature review

Purpose – The purpose of this paper is to examine the relationship between Bass’s (1985) leadership dimensions (transformational, transactional, and laissez-faire) and several outcome variables (employee extra effort, employee satisfaction with leader, leadership effectiveness) and organizational commitment. Design/methodology/approach – This is a systematic literature review. Findings – This review briefly discusses the conceptual framework and the Full Range Leadership Model (Bass, 1985) which include transformational leadership, transactional leadership, and laissez-faire leadership. Also discussed in this section were the abilities and the characteristics of transformational leaders. The leadership section was concluded with discussion on previous researches on transformational leadership. This review also provides a literature review on organizational commitment. Originality/value – Described in this paper are the various definitions of organizational commitment and the three-component model of commitment. This paper also described the antecedents and outcomes of organizational commitment obtained from previous researches. This paper concluded with a discussion on the impact of transformational leadership on employee organizational commitment.
Localized air-conditioning with occupancy control in an open office

Conditioning and ventilating open office spaces requires innovations as new buildings aim to be more intelligent, energy efficient and healthy. This paper explores the possibility of using a localized airflow to divide an open cubicle office into zones without partition walls. Computational fluid dynamics (CFD) model was used to simulate localized airflow in a cubicle office and both the energy and the indoor air quality concerns were addressed. The findings suggest that (1) localized airflow is plausible for zoning purposes, (2) localized airflow can result in both temperature and pollutant concentration segregations, (3) temperature segregations provide possible energy savings if coupled with occupancy-based HVAC control, and finally (4) limited air mixing between zones provide a novel way for better ventilation and indoor contaminant control. 2010 Elsevier B.V.

Multi-Center Evaluation of Post-Operative Morbidity and Mortality after Optimal Cytoreductive Surgery for Advanced Ovarian Cancer

PURPOSE
While optimal cytoreduction is the standard of care for advanced ovarian cancer, the related post-operative morbidity has not been clearly documented outside pioneering centers. Indeed most of the studies are monocentric with inclusions over several years inducing heterogeneity in techniques and goals of surgery. We assessed the morbidity of optimal cytoreduction surgery for advanced ovarian cancer within a short inclusion period in 6 referral centers dedicated to achieve complete cytoreduction.


PATIENTS AND METHODS
The 30 last optimal debulking surgeries of 6 cancer centers were included. Inclusion criteria included: stage IIIc- IV ovarian cancer and optimal surgery performed at the site of inclusion. All post-operative complications within 30 days of surgery were recorded and graded using the Memorial secondary events grading system. Student-t, Chi2 and non-parametric statistical tests were performed.


RESULTS
180 patients were included. There was no demographic differences between the centers. 63 patients underwent surgery including intestinal resections (58 recto-sigmoid resection), 24 diaphragmatic resections, 17 splenectomies. 61 patients presented complications; One patient died post-operatively. Major (grade 3-5) complications requiring subsequent surgeries occurred in 21 patients (11.5%). 76% of patients with a major complication had undergone an ultraradical surgery (P = 0.004).


CONCLUSION
While ultraradical surgery may result in complete resection of peritoneal disease in advanced ovarian cancer, the associated complication rate is not negligible. Patients should be carefully evaluated and the timing of their surgery optimized in order to avoid major complications.
Patient centred care - cultural safety in indigenous health.

BACKGROUND
The terms 'cultural safety' and 'cultural competence' are used widely in indigenous and culturally and linguistically diverse health contexts. They form the basis for effective patient centred care and the professional advocacy role of the general practitioner.


OBJECTIVE
This article discusses the concepts of cultural safety and cultural competence. A checklist of cultural competency practice is also provided for health practitioners.


DISCUSSION
Cultural safety is the experience of the recipient of care. It is comparable to clinical safety, allowing the patient to feel safe in health care interactions and be involved in changes to health services. It has been suggested that cultural safety training may be one mechanism to reduce disparities in indigenous health status. Cultural competence is a broader term that focuses on the capacity of the health system to improve health and wellbeing by integrating culture into the delivery of health services.

Neuroanatomical basis of paroxysmal sympathetic hyperactivity: a diffusion tensor imaging analysis.

PRIMARY OBJECTIVE
Paroxysmal sympathetic hyperactivity (PSH) is observed in a sub-set of patients with moderate-to-severe traumatic brain injury (TBI). The neuroanatomical basis of PSH is poorly understood. It is hypothesized that PSH is linked to changes in connectivity within the central autonomic network.


RESEARCH DESIGN
Retrospective analysis in a sub-set of patients from a multi-centre, prospective cohort study Methods and procedures: Adult patients who were <3 weeks after severe TBI were enrolled and screened for PSH using a standard definition. Patients underwent multimodal MRI, which included quantitative diffusion tensor imaging.


MAIN OUTCOMES AND RESULTS
Principal component analysis (PCA) was used to resolve the set of tracts into components. Ability to predict PSH was evaluated via area under the receiver operating characteristic (AUROC) and tree-based classification analyses. Among 102 enrolled patients, 16 met criteria for PSH. The first principle component was significantly associated (p = 0.024, AUROC = 0.867) with PSH status even after controlling for age and admission GCS. In a classification tree analysis, age, GCS and decreased FA in the splenium of the corpus callosum and in the right posterior limb of the internal capsule discriminated PSH vs no PSH with an AUROC of 0.933.


CONCLUSIONS
Disconnection involving the posterior corpus callosum and of the posterior limb of the internal capsule may play a role in the pathogenesis or expression of PSH.
Detection of CDT toxin genes in Campylobacter spp. strains isolated from broiler carcasses and vegetables in São Paulo, Brazil

Campylobacteriosis is a worldwide distributed zoonosis. One of the main virulence factors related to Campylobacter spp. in animals and humans is the cytolethal distending toxin (CDT), encoded by three adjacent genes (cdtA, cdtB, cdtC). The occurrence of Campylobacter spp. in samples of vegetables has not been reported in Brazil yet, and has seldom been described in the international literature. The detection of CDT in these strains has not been reported, either. The objectives of the present study were to determine the occurrence of Campylobacter spp. strains carrying virulence factors in samples of poultry and vegetables (lettuce and spinach) from different points of sale, thus verifying if vegetables are as an important vehicle for potentially virulent Campylobacter spp. strains as poultry. Twenty four strains were identified as Campylobacter jejuni by phenotypic and genotypic methods: 22 from broiler carcasses and two from lettuce samples. Three strains were identified as Campylobacter coli: two from broiler carcasses and one from lettuce. The presence of the cdt genes were detected in 20/24 (83.3%) C. jejuni strains, and 3/3 (100%) C. coli strains. The isolation of Campylobacter spp. strains with the cdt gene cluster in lettuce samples points to a new possible source of contamination, which could have an impact in the vegetable production chain and risk to public health. Results show that potentially virulent C. jejuni and C. coli strains remain viable in samples of broiler carcasses and vegetables at the points of sale.
Who’s the Fool, and Why? Paul on Wisdom from a South African Perspective

Abstract South Africa is a young democracy but with colonial and Apartheid legacies fresh in the minds of many, the lasting impact and consequences of hegemony still tangible and measurable in a new, democratic dispensation with its own problems and concerns. This is the context within which Paul’s appeal for a different understanding of wisdom and appearance to insist on breaking through the conventions of the day (1 Cor 1:18–31) is considered. Since Empire largely defined wisdom in the first century, Paul’s rhetoric of foolishness can be interpreted as a critique of the imperial discourse of wisdom and power. But Paul simultaneously invoked a new discourse of power through his rhetoric which inter alia depended on scriptural appeal for endorsement or authority. A postcolonial optic enables one to see Paul’s discourse as mimicry, negotiating power as much with discursive Roman colonialism as with the recipients of his letters, and also with the Scriptures of Israel. Such use of discursive power and ambiguity resonates in interesting ways in the South African context.

Classification and synthesis of quality approaches in e-government services

Purpose – The purpose of this paper is to present a multi-faceted summary and classification of the existing literature in the field of quality of service for e-government and outline the main components of a quality model for e-government services. Design/methodology/approach – Starting with fundamental quality principles the paper examines and analyzes 36 different quality approaches concerning public sector services, e-services in general and more specifically e-government services. Based on the dimensions measured by each approach the paper classifies the approaches and concludes on the basic factors needed for the development of a complete quality model of e-government services. Findings – Based on the classification of literature approaches, the paper provides information about the main components of a quality model that may be used for the continuous monitoring and measuring of public e-services’ quality. The classification forms the basis for answering questions that must be addressed by the quality model, such as: What to assess?; Who will perform the assessment? and How the assessment will be done? Practical implications – This model can be used by the management of public organizations in order to measure and monitor the quality of e-services delivered to citizens. Originality/value – The results of the work presented in this paper form the basis for the development of a quality model for e-government services.
Automated chest screening based on a hybrid model of transfer learning and convolutional sparse denoising autoencoder

OBJECTIVE
In this paper, we aim to investigate the effect of computer-aided triage system, which is implemented for the health checkup of lung lesions involving tens of thousands of chest X-rays (CXRs) that are required for diagnosis. Therefore, high accuracy of diagnosis by an automated system can reduce the radiologist's workload on scrutinizing the medical images.


METHOD
We present a deep learning model in order to efficiently detect abnormal levels or identify normal levels during mass chest screening so as to obtain the probability confidence of the CXRs. Moreover, a convolutional sparse denoising autoencoder is designed to compute the reconstruction error. We employ four publicly available radiology datasets pertaining to CXRs, analyze their reports, and utilize their images for mining the correct disease level of the CXRs that are to be submitted to a computer aided triaging system. Based on our approach, we vote for the final decision from multi-classifiers to determine which three levels of the images (i.e. normal, abnormal, and uncertain cases) that the CXRs fall into.


RESULTS
We only deal with the grade diagnosis for physical examination and propose multiple new metric indices. Combining predictors for classification by using the area under a receiver operating characteristic curve, we observe that the final decision is related to the threshold from reconstruction error and the probability value. Our method achieves promising results in terms of precision of 98.7 and 94.3% based on the normal and abnormal cases, respectively.


CONCLUSION
The results achieved by the proposed framework show superiority in classifying the disease level with high accuracy. This can potentially save the radiologists time and effort, so as to allow them to focus on higher-level risk CXRs.
Towards a Universal Implementation Substrate for Object-Oriented Languages

Self is a minimalist object-oriented language with a sophisticated implementation that utilizes adaptive optimization. We have built implementations of Smalltalk and Java by translation to Self. These implementations were much easier to construct in Self than by conventional means, and perform surprisingly well (competitively with conventional, commercial implementations). This leads us to believe that a Self-like system may form the basis of a universal substrate for implementation of object-oriented languages. This paper was presented at the OOPSLA 99 workshop on Simplicity, Performance and Portability in Virtual Machine Design, Denver, CO, Nov 2, 1999. 1 Building virtual machines is hard Building a high-performance virtual machine (VM) for an object-oriented language such as Smalltalk or JavaTM 2 is a major undertaking. The conventional approach has been to hand-craft the entire VM in a systems language such as C or C++. The low-level access afforded by such a language, compared to using a higher level language, enables an efficient implementation of necessary components, such as a garbage collector, bytecode interpreter, dynamic compiler, and object storage system. Access to the hardware is important because many central data structures and algorithms must be tightly coded if the resulting VM is to perform well and use memory efficiently. Details such as object layout, inner loops of the garbage collector, and code sequences emitted by a dynamic compiler, must all be well tuned for maximum performance. C and C++ serve the role of “structured assembly language” in these cases, because the code emitted by optimizing C and C++ compilers is predictable and efficient. Performance of certain sections of code, such as the message dispatch sequence, is so critical that in some circumstances even these languages are not suitable, and hand-crafted machine code sequences are used to squeeze the last drop of efficiency from the machine. Hand-crafting a VM in this way is very laborious. The efficiency gained by using C or C++ is at the cost of security; array accesses are not checked to see whether they are within bounds, errors in memory management can lead to memory leaks or dangling pointers, and unchecked type coercions can result in erroneous accesses. A high-performance VM will contain many tens of thousands of lines of source code (e.g., the Self VM 1.

Marginalized transition models for longitudinal binary data with ignorable and non-ignorable drop-out.

We extend the marginalized transition model of Heagerty to accommodate non-ignorable monotone drop-out. Using a selection model, weakly identified drop-out parameters are held constant and their effects evaluated through sensitivity analysis. For data missing at random (MAR), efficiency of inverse probability of censoring weighted generalized estimating equations (IPCW-GEE) is as low as 40 per cent compared to a likelihood-based marginalized transition model (MTM) with comparable modelling burden. MTM and IPCW-GEE regression parameters both display misspecification bias for MAR and non-ignorable missing data, and both reduce bias noticeably by improving model fit.
Incidence and Factors Associated With the Occurrence of Pulmonary Vein Narrowing After Cryoballoon Ablation.

BACKGROUND
In contrast with traditional radiofrequency ablation, little is known about the influence of cryoballoon ablation on the morphology of pulmonary veins (PVs). We evaluated the influence of cryoballoon ablation on the PV dimension (PVD) and investigated the factors associated with a reduction of the PVD.


METHODS AND RESULTS
Seventy-four patients who underwent cryoballoon ablation for paroxysmal atrial fibrillation were included in the present study. All subjects underwent contrast-enhanced computed tomography both before and at 3 months after the procedure. The PVD (cross-sectional area) was measured using a 3-dimensional electroanatomical mapping system. Each PV was evaluated according to the PVD reduction rate (ΔPVD), which was calculated as follows: (1-post-PVD/pre-PVD)×100 (%). Ninety-two percent of the PVs (271/296) were successfully isolated only by cryoballoon ablation; the remaining 8% of the PVs required touch-up ablation and were excluded from the analysis. Mild (25%-50%), moderate (50%-75%), and severe (≥75%) ΔPVD values were observed in 87, 14, and 3 PVs, respectively, including 1 case with severe left superior PV stenosis (ΔPVD: 94%) in a patient who required PV angioplasty. In multivariable analysis, a larger PV ostium and lower minimum freezing temperature during cryoballoon ablation were independently associated with PV narrowing (odds ratio, 1.773; P=0.01; and odds ratio, 1.137; P<0.001, respectively).


CONCLUSIONS
A reduction of the PVD was often observed after cryoballoon ablation for atrial fibrillation. A larger PV ostium and lower minimum freezing temperature during cryoballoon ablation were associated with an increased risk of PVD reduction.
