Effect of laparoscopic and conventional colorectal resection on peritoneal fibrinolytic capacity: a prospective randomized clinical trial

Background and aims: Reduced fibrinolytic activity of the peritoneum seems to be the main cause of postoperative adhesions. This prospective randomized trial compared the peritoneal fibrinolytic activity between laparoscopic and conventional colorectal resection. Methods: Parietal peritoneal biopsy specimens were taken in standardized elective laparoscopic (n=14) and conventional (n=16) colorectal resections at the beginning and at the end of surgery. Activities and concentrations of tissue-plasminogen activator (tPA), plasminogen activator (PAI) type 1, and tPA/PAI complex were determined by ELISA kits. Results: There was no difference in age, sex, or body mass index between the two groups. Perioperative tPA activity decreased in both groups without differences between the groups. Concentrations and activities of tPA, PAI-1, and tPA/PAI complex did not differ between the groups at any time. Conclusion: Peritoneal concentrations and activities of tPA, PAI-1, and tPA/PAI complex are similar during laparoscopic and conventional colorectal resections. A capnoperitoneum of 12 mmHg over 3 h did not affect the peritoneal fibrinolytic activity
Estimation of blood pressure using Photoplethysmography on the wrist

Adaptive Compensation for Power Amplifier Nonlinearity in the Presence of Quadrature Modulation/Demodulation Errors

This correspondence proposes techniques that jointly compensate for amplifier nonlinearity and quadrature modulation/demodulation (QM/QDM) errors. The proposed methods are derived based on the polynomial predistortion (PD) employing the indirect learning technique and do not require any additional feedback loop for QM/QDM-error compensation. Compared with the existing joint compensation technique, the proposed methods need some additional parameters to be estimated but exhibit faster convergence and better performance. The advantage of the proposed technique is demonstrated through computer simulation.
Polymer Optoelectronic Devices with High-Conductivity Poly(3,4-Ethylenedioxythiophene) Anodes

The conductivity of poly(3,4-ethylenedioxythiophene) : polystyrenesulfonate (PEDOT : PSS) film can be enhanced by more than two orders in magnitude by adding a compound with two or more polar groups, such as ethylene glycol (EG), mesoerythritol (IUPAC name: 1,2,3,4-tetrahydroxybutane), or 2-nitroethanol, into the PEDOT : PSS aqueous solution. The mechanism of the increase in conductivity for PEDOT : PSS has been studied using Raman spectroscopy and atomic force microscope (AFM). Here we propose that the change in conductivity is due to the conformational change of PEDOT chains in the film. In untreated PEDOT : PSS films, coil, linear, or expanded-coil conformations of the PEDOT chains may be present. In treated PEDOT : PSS films, the linear or expanded-coil conformations may becomes the dominant form for PEDOT chains. This conformational change results in the enhancement of charge-carrier mobility in the film and leads to enhanced conductivity. The high-conductivity PEDOT : PSS film is ideal as the electrode for polymer optoelectronic devices. In this article, we report on the fabrication of polymer light-emitting diodes (PLEDs) and photovoltaic cells (PVs) made using a

Closure of elective abdominal incisions with monofilament, non-absorbable suture material versus polyfilament absorbable suture material.

BACKGROUND
Closure of abdominal incisions with different suture materials has been a matter of great controversy. Polypropylene and Polylactide with Polyglycolide are among the commonest suture materials used for closure of abdominal incisions. Objectives of this study were to assess optimal suture material used for closure of elective abdominal incisions and to see complications associated with these suture materials.


METHODS
This prospective, comparative, randomised study was conducted at public and private sector hospitals of Nawabshah and Hyderabad from 1st Jan 2005 to 31st October 2009. All patients who underwent abdominal surgery under the investigators' supervision were included in the study. Patients were divided into 2 groups on even or odd numbers. In group-A patients' incision was closed with monofilament, non-absorbable Polypropylene (Prolene) No. 1 suture material and in group-B incision was closed with Polyfilament, absorbable, co-polymer of Polylactide with Polyglycolide (Vicryle) No. 1.


RESULTS
A total 274 patients were finally analysed for closure of elective abdominal incisions, with 138 (50.4%) patients in Group-A and 136 (49.6%) patients in Group-B. Vicryle was found superior in knot security and suture handling. Superficial wound infection was found in 5.79% patients of Group-A and 6.61% of Group-B. Discharging sinus was found in 3.62% of Group-A vs 0.73% of Group-B. Burst abdomen was seen in 2.17% patients in Group-A and 1.47% in Group-B. Incisional hernia was present in 4.34% of Group-A and 0.73% patients of Group-B. No patient in Group-B developed persistent pain at incisional site while it was found in 8.69% patients of Group-A.


CONCLUSION
Polylactide is an optimal suture material in closure of elective abdominal incisions.
Association of door-to-balloon time and mortality in patients admitted to hospital with ST elevation myocardial infarction: national cohort study

OBJECTIVE
To evaluate the association between door-to-balloon time and mortality in hospital in patients undergoing primary percutaneous coronary intervention for ST elevation myocardial infarction to assess the incremental mortality benefit of reductions in door-to-balloon times of less than 90 minutes.


DESIGN
Prospective cohort study of patients enrolled in the American College of Cardiology National Cardiovascular Data Registry, 2005-6.


SETTING
Acute care hospitals.


PARTICIPANTS
43 801 patients with ST elevation myocardial infarction undergoing primary percutaneous coronary intervention.


MAIN OUTCOME MEASURE
Mortality in hospital.


RESULTS
Median door-to-balloon time was 83 minutes (interquartile range 6-109, 57.9% treated within 90 minutes). Overall mortality in hospital was 4.6%. Multivariable logistic regression models with fractional polynomial models indicated that longer door-to-balloon times were associated with a higher adjusted risk of mortality in hospital in a continuous non-linear fashion (30 minutes=3.0%, 60 minutes=3.5%, 90 minutes=4.3%, 120 minutes=5.6%, 150 minutes=7.0%, 180 minutes=8.4%, P<0.001). A reduction in door-to-balloon time from 90 minutes to 60 minutes was associated with 0.8% lower mortality, and a reduction from 60 minutes to 30 minutes with a 0.5% lower mortality.


CONCLUSION
Any delay in primary percutaneous coronary intervention after a patient arrives at hospital is associated with higher mortality in hospital in those admitted with ST elevation myocardial infarction. Time to treatment should be as short as possible, even in centres currently providing primary percutaneous coronary intervention within 90 minutes.
Learning Under Ambiguity

This paper considers learning when the distinction between risk and ambiguity (Knightian uncertainty) matters. Working within the framework of recursive multiple-priors utility, the paper formulates a counterpart of the Bayesian model of learning about an uncertain parameter from conditionally i.i.d. signals. Ambiguous signals capture responses to information that cannot be captured by noisy signals. They induce nonmonotonic changes in agent confidence and prevent ambiguity from vanishing in the limit. In a dynamic portfolio choice model, learning about ambiguous returns leads to endogenous stock market participation costs that depend on past market performance. Hedging of ambiguity provides a new reason why the investment horizon matters for portfolio choice. ∗Department of Economics, U.

Re-thinking ethical leadership : An interdisciplinary integrative approach ☆

Article history: Received 21 March 2011 Revised 28 February 2012 Accepted 5 March 2012 Available online 26 March 2012 The purpose of this paper is (1) to identify critical issues in the current literature on ethical leadership — i.e., the conceptual vagueness of the construct itself and the focus on a Western-based perspective; and (2) to address these issues and recent calls for more collaboration between normative and empirical-descriptive inquiry of ethical phenomena by developing an interdisciplinary integrative approach to ethical leadership. Based on the analysis of similarities between Western and Eastern moral philosophy and ethics principles of the world religions, the present approach identifies four essential normative reference points of ethical leadership— the four central ethical orientations: (1) humane orientation, (2) justice orientation, (3) responsibility and sustainability orientation, and (4) moderation orientation. Research propositions on predictors and consequences of leader expressions of the four central orientations are offered. Real cases of ethical leadership choices, derived from in-depth interviews with international leaders, illustrate how the central orientations play out in managerial practice. © 2012 Elsevier Inc.

Logic Program Synthesis in a Higher-Order Setting

We describe a system for the synthesis of logic programs from specifications based on higher-order logical descriptions of appropriate refinement operations. The system has been implemented within the proof planning system λClam. The generality of the approach is such that its extension to allow synthesis of higher-order logic programs was straightforward. Some illustrative examples are given. The approach is extensible to further classes of synthesis.
A Transformation from RDF Documents and Schemas to Relational Databases

At present, resource description framework (RDF) documents and schemas (RDFS) are used to describe information in the semantic Web. Many research works regard the RDF/RDFS documents as databases and proposed data manipulations for them. This research paper takes a different approach. In order to easily manipulate the database, RDF/RDFS documents are transformed into relational database format so that relational languages, data management and business intelligence facilities which are readily available can be exploited. A conceptual meta schema that describes RDF/RDFS documents and the corresponding meta table are presented together with illustrated examples.

Semi-Active Control of Structures Using a Neuro-Inverse Model of MR Dampers

A semi-active controller-based neural network for a 3 story nonlinear benchmark structure equipped with a Magneto Rheological (MR) damper is presented and evaluated. An inverse neural network model (NIMR) is constructed to replicate the inverse dynamics of the MR damper. A Linear Quadratic Gaussian (LQG) controller is also designed to produce the optimal control force. The LQG controller and the NIMR models are linked to control the structure. The e ectiveness of the NIMR is illustrated and veri ed using the simulated response of a full-scale, nonlinear, seismically excited, 3-story benchmark building excited by several historical earthquake records. The semi-active system using the NIMR model is compared to the performance of an active LQG and a Clipped Optimal Control (COC) system, which is based on the same nominal controller as used in the NIMR damper control algorithm. Two passive control systems are also considered and compared. The results demonstrate that by using the NIMR model, the MR damper force can be commanded to follow closely the desirable optimal control force. The results also show that the control system is e ective, and achieves better performance than active LQG and COC system. The optimal passive controller performs better than the NIMR. However, the performance of NIMR will be improved if a more e ective active controller is replaced by a LQG controller.
The evolution of supportive care needs trajectories in women with advanced breast cancer during the 12 months following diagnosis

This longitudinal study examined if the evolution of supportive care needs differed over the first year following the diagnosis of advanced breast cancer and examined factors differentiating these trajectories. Two hundred twenty-eight of 276 Chinese women with advanced breast cancer were assessed while they were awaiting or receiving initial chemotherapy, then again at 6 weeks, 3 months, 6 months, and 12 months post-baseline. Supportive care needs (SCNS-34-Ch), psychological distress (Hospital Anxiety and Depression scale), symptom distress (MSAS-Ch), and patient satisfaction (PSEQ-9) were assessed at baseline; supportive care needs were reassessed at each follow-up assessment. Latent growth mixture modeling explored if trajectories differed within each of four need domains: health system, information, and patient support (HSIPS); psychological; physical daily living (PDL); and sexuality needs. Logistic regression identified factors predicting trajectory patterns. Two distinct trajectories were identified for HSIPS and sexuality need domains and three distinct trajectories for psychological and physical daily living need domains. Most women showed stable low levels of HSIPS (78.9 %), psychological (82.4 %), PDL (83.7 %), and sexuality (97.4 %) supportive care needs. One in five and one in eight women showed high initial supportive care needs in HSIPS and psychological and PDL domains, respectively. With the exception of sexuality needs, trajectory patterns were predicted by physical symptom distress. Women in the high-decline group reported greater physical symptom distress. Most Chinese women with advanced breast cancer showed low stable supportive care needs. Physical symptom distress predicted high supportive care needs. Interventions should focus on optimizing symptom assessment and management.

Antibiotic Susceptibility Pattern of Aerobic and Anaerobic Bacteria Isolated From Surgical Site Infection of Hospitalized Patients

BACKGROUND
Surgical Site Infections (SSIs) are infections of incision or deep tissue at operation sites. These infections prolong hospitalization, delay wound healing, and increase the overall cost and morbidity.


OBJECTIVES
This study aimed to investigate anaerobic and aerobic bacteria prevalence in surgical site infections and determinate antibiotic susceptibility pattern in these isolates.


MATERIALS AND METHODS
One hundred SSIs specimens were obtained by needle aspiration from purulent material in depth of infected site. These specimens were cultured and incubated in both aerobic and anaerobic condition. For detection of antibiotic susceptibility pattern in aerobic and anaerobic bacteria, we used disk diffusion, agar dilution, and E-test methods.


RESULTS
A total of 194 bacterial strains were isolated from 100 samples of surgical sites. Predominant aerobic and facultative anaerobic bacteria isolated from these specimens were the members of Enterobacteriaceae family (66, 34.03%) followed by Pseudomonas aeruginosa (26, 13.4%), Staphylococcus aureus (24, 12.37%), Acinetobacter spp. (18, 9.28%), Enterococcus spp. (16, 8.24%), coagulase negative Staphylococcus spp. (14, 7.22%) and nonhemolytic streptococci (2, 1.03%). Bacteroides fragilis (26, 13.4%), and Clostridium perfringens (2, 1.03%) were isolated as anaerobic bacteria. The most resistant bacteria among anaerobic isolates were B. fragilis. All Gram-positive isolates were susceptible to vancomycin and linezolid while most of Enterobacteriaceae showed sensitivity to imipenem.


CONCLUSIONS
Most SSIs specimens were polymicrobial and predominant anaerobic isolate was B. fragilis. Isolated aerobic and anaerobic strains showed high level of resistance to antibiotics.
Historicity and the Politics of Predication

I begin with a kind of phenomenological reporting of the recent war between Israel and the Hezbollah in Lebanon, in order to explain the meaning of the thesis that "historicity is predication" – meaning by that to clarify the sense in which predication is a kind of political act (for good and sufficient philosophical reasons) and how the "objective" description of an evolving war illuminates such a philosophical reading of history.
Autonomous control of inverter-interfaced Distributed Generation units for harmonic current filtering and resonance damping in an islanded microgrid

Harmonic current filtering and resonance damping have become important concerns on the control of an islanded microgrids. To address these challenges, this paper proposes a control method of inverter-interfaced Distributed Generation (DG) units, which can autonomously share harmonic currents and resonance damping burdens. The approach employs a load compensator based on the decomposition of output current, in addition to the outer droop-based power controller, as well as inner voltage and current controllers. The load compensator consists of a virtual fundamental impedance loop for enhanced sharing of reactive power, and a variable harmonic impedance loop which allows to counteract harmonic voltage drops across the grid-side inductance of the DG inverter, and to damp the harmonic resonance propagation throughout a distribution feeder. Experiments on a three-phase microgrid are performed to validate the performance of the proposed control scheme.
Breast Cancer Detection Based on Incremental Biochemical and Physiological Properties of Breast Cancers : A Six-Year , Two-Site Study 1

Rationale and Objectives. To demonstrate that near-infrared spectroscopy would achieve sufficient sensitivity and specificity in human breast cancer to reach ROC/AUC values in the 90s and yet to warn of the potential liabilities of introduction of a novel technology in this field. Materials and Methods. 116 subjects from two nations (44 were cancer-verified by biopsy and histopathology) were reviewed. NIR spectroscopy of total hemoglobin and its relative oxygenation were monitored in breast cancers and compared to their contralateral breast in a 2D nomogram for diagnostic evaluation. A novel handheld NIR breast cancer detector pad with a 3-wavelength LED and 8 detectors with 4 cm separation between source and detectors was placed on the subject’s breast. The method is convenient, rapid, and safe and has achieved high patient compliance with minimal patient apprehension of compression, confinement, or radioactivity. Results. The absorbance increments of the cancerous region are referred to the mirror image location on the contralateral breast. The two metrics are increased hemoglobin concentration due to angiogenesis and decreased hemoglobin saturation due to hypermetabolism of the cancer. The 2D nomogram display of these two metrics shows Zone 1 contains verified cancers and Zone 2 contains noncancers. ROC evaluation of the nomogram gives 95% AUC for the two sites, Philadelphia and Leipzig. Conclusion. A simple, economical breast cancer detector has achieved high patient compliance and a high ROC/AUC score for a population which involved a range of tumors down to and including those of 0.8–1 cm in diameter.
