Randomized, Controlled, Blinded Trial of Tisseel/Tissucol for Mesh Fixation in Patients Undergoing Lichtenstein Technique for Primary Inguinal Hernia Repair Results of the TIMELI Trial
No full textObjective: Test the hypothesis that fibrin sealant mesh fixation can reduce the incidence of postoperative pain/numbness/groin discomfort by up to 50% compared with sutures for repair of inguinal hernias using the Lichtenstein technique. Background: Inguinal hernia repair is the most common procedure in general surgery, thus improvements in surgical techniques, which reduce the burden of undesirable postoperative outcomes, are of clinical importance. Methods: A randomized, controlled, patient-and evaluator-blinded study (Tissucol/Tisseel for MEsh fixation in LIchtenstein hernia repair [TIMELI]; trial NCT00306839) was conducted among patients eligible for Lichtenstein repair of uncomplicated unilateral primary inguinal small-medium sized hernia. Patients were subject to mesh fixation with either fibrin sealant or sutures. Main outcome measures were visual analogue scale (VAS) assessments for "pain," "numbness," and "groin discomfort" on a scale of 0 = best and 100 = worst outcome. The primary endpoint was a composite that evaluated the prevalence of chronic disabling complications (VAS score >30 for pain/numbness/groin discomfort) at 12 months after surgery. Results: In total, 319 patients were randomized between January 2006 and April 2007 (159 fibrin sealant, 160 sutures). At 12 months, the prevalence of 1 or more disabling complication was significantly lower in the fibrin sealant group than in the sutures group (8.1% vs 14.8%; P = 0.0344). Less pain was reported in the fibrin sealant group than in the sutures group at 1 and 6 months (P = 0.0132; P = 0.0052), as reflected by a lower proportion of patients using analgesics in the fibrin group over the study duration (65.2% vs 79.7%; P = 0.0009). Only 3 of 316 patients (0.9%) experienced recurrence. The incidences of wound-healing complications and other adverse events were comparable between groups. Conclusions: Fibrin sealant for mesh fixation in Lichtenstein repair of small-medium sized inguinal hernias is well tolerated and reduces the rate of pain/numbness/groin discomfort by 45% relative to sutures without increasing hernia recurrence (NCT00306839

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
No full textAnswering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
Post-operative benefits of Tisseel®/Tissucol®for mesh fixation in patients undergoing Lichtenstein inguinal hernia repair: secondary results from the TIMELI trial
No full textPurpose: The Tisseel/Tissucol for mesh fixation in Lichtenstein hernia repair (TIMELI) study showed that mesh fixation with human fibrin sealant during inguinal hernia repair significantly reduced moderate–severe complications of pain 12 months post-operatively compared with sutures. Further analyses may assist surgeons by investigating predictors of post-surgical complications and identifying patients that may benefit from Tisseel/Tissucol intervention.
Methods: Univariate and multivariate analyses identified risk factors for combined pain, numbness and groin discomfort (PND) visual analogue scale (VAS) score 12 months post-operatively. Variables tested were: fixation method, age, employment status, physical activity, nerve handling, PND VAS score at pre-operative visit and 1 week post-operatively. The effect of fixation technique on separate PND outcomes 12 months post-surgery was also assessed. Analyses included the intention-to-treat (ITT) population and a subpopulation with pre-operative PND VAS > 30 mm.
Results: 316 patients were included in the ITT, with 130 patients in the subpopulation with pre-operative PND VAS > 30. Multivariate analysis identified mesh fixation with sutures, worsening pre-operative PND and worsening PND 1 week post-surgery as significant predictors of 12-month PND in the ITT population; mesh fixation with sutures was a significant predictor of 12-month PND in the pre-operative PND VAS > 30 subpopulation (p < 0.05). Mesh fixation with Tisseel/Tissucol resulted in significantly less numbness and a lower intensity of groin discomfort compared with sutures at 12 months; there was no difference in pain between the treatment groups.
Conclusions: Pre-operative discomfort may be an important predictor of post-operative pain, numbness and discomfort. Tisseel/Tissucol may improve long-term morbidity over conventional sutures in these patients
Randomized, controlled, blinded trial of Tissucol/Tisseel for mesh fixation in patients undergoing Lichtenstein technique for primary inguinal hernia repair: Rationale and study design of the TIMELI trial
No full textBackground Complications associated with sutured mesh
fixation following open groin hernia repair have prompted
surgeons to evaluate methods of atraumatic fixation such as
the use of human fibrin glue. Small trials with Tissucol/Tisseel
fibrin glue (Baxter Healthcare, Deerfield, IL, USA)
have shown promising results that warrant further investigation.
Methods TIMELI (Tissucol/Tisseel for MEsh fixation in
LIchtenstein hernia repair) is an international, controlled,
randomized, patient- and evaluator-blinded study that is
comparing mesh fixation with Tissucol or sutures in patients with inguinal hernia. The primary endpoint evaluates
the incidence of disabling complications (chronic pain
and/or numbness and/or groin discomfort) at 12 months
post-surgery.
Results Patient enrolment started in February 2006 and
ended on 19 April 2007, with a total of 325 patients
recruited. Initial results are expected in early 2008.
Conclusions TIMELI is a major international trial that
will provide important information on the efficacy and
safety of Tissucol, compared with sutures, for mesh fixation
in patients undergoing Lichtenstein technique for primary
inguinal hernia repair
G-Rank: Unsupervised Continuous Learn-to-Rank for Edge Devices in a P2P Network
No full textRanking algorithms in traditional search engines are powered by enormous training data sets that are meticulously engineered and curated by a centralized entity. Decentralized peer-to-peer (p2p) networks such as torrenting applications and Web3 protocols deliberately eschew centralized databases and computational architectures when designing services and features. As such, robust search-and-rank algorithms designed for such domains must be engineered specifically for decentralized networks, and must be lightweight enough to operate on consumer-grade personal devices such as a smartphone or laptop computer. We introduce G-Rank, an unsupervised ranking algorithm designed exclusively for decentralized networks. We demonstrate that accurate, relevant ranking results can be achieved in fully decentralized networks without any centralized data aggregation, feature engineering, or model training. Furthermore, we show that such results are obtainable with minimal data preprocessing and computational overhead, and can still return highly relevant results even when a user’s device is disconnected from the network. G-Rank is highly modular in design, is not limited to categorical data, and can be implemented in a variety of domains with minimal modification. The results herein show that unsupervised ranking models designed for decentralized p2p networks are not only viable, but worthy of further research.https://github.com/awrgold/G-RankComputer Scienc
