Binge eating and exercise behavior after surgery for severe obesity: A structural equation model

INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 5 2006
Junilla K. Larsen PhD
Abstract Objective: The current study sought to find indications for the appropriateness of a model in which eating patterns and exercise beliefs influence binge eating and physical exercise, respectively, that, in turn, influence outcome after gastric banding for severe obesity. Method: Participants were 157 patients (144 females, 13 males) who completed questionnaires approximately 34 months (range = 8,68 months) after laparoscopic adjustable gastric banding (LAGB). Results: Our data showed a well-fitting model in which external and emotional eating were associated with outcome through binge eating. Several exercise beliefs were associated with physical exercise, but physical exercise was not associated with weight loss or physical health. Conclusion: Binge eating was related more strongly to the outcome after gastric banding than physical exercise. Future research should examine whether a strong focus on the management of binge eating and external and emotional eating could improve the outcome of morbidly obese patients with unsuccessful weight outcome after obesity surgery. © 2006 by Wiley Periodicals, Inc.

The Current and Future Role of Percutaneous Coronary Intervention in Patients with Coronary Artery Disease

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 5 2004
MICHAEL J. LIPINSKI B.S.
With increasing research on vulnerable plaques and uncertainty regarding which lesions require revascularization, the goal of this review is to clarify the indications for percutaneous coronary intevention and discuss which lesions do not warrant treatment by intervention. This paper also briefly reviews the potential advantages and limitations of technology that may enable detection of atherosclerotic plaques that are prone to rupture and discusses the future utility of these technologies in prevention of acute coronary syndromes. Providing an evidence-based understanding of lesion morphology and clinical variables that influence outcome enables the interventional cardiologist to determine which atherosclerotic plaques require PCI.

Multicenter Analysis of Novel and Established Variables Associated with Successful Human Islet Isolation Outcomes

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 3 2010
J. S. Kaddis
Islet transplantation is a promising therapy used to achieve glycometabolic control in a select subgroup of individuals with type I diabetes. However, features that characterize human islet isolation success prior to transplantation are not standardized and lack validation. We conducted a retrospective analysis of 806 isolation records from 14 pancreas-processing laboratories, considering variables from relevant studies in the last 15 years. The outcome was defined as postpurification islet equivalent count, dichotomized into yields ,315 000 or ,220 000. Univariate analysis showed that donor cause of death and use of hormonal medications negatively influenced outcome. Conversely, pancreata from heavier donors and those containing elevated levels of surface fat positively influence outcome, as did heavier pancreata and donors with normal amylase levels. Multivariable logistic regression analysis identified the positive impact on outcome of surgically intact pancreata and donors with normal liver function, and confirmed that younger donors, increased body mass index, shorter cold ischemia times, no administration of fluid/electrolyte medications, absence of organ edema, use of University of Wisconsin preservation solution and a fatty pancreas improves outcome. In conclusion, this multicenter analysis highlights the importance of carefully reviewing all donor, pancreas and processing parameters prior to isolation and transplantation. [source]


Intravasal azoospermia: a surgical dilemma

BJU INTERNATIONAL, Issue 9 2000
Y.R. Sheynkin
Objectives,To determine the incidence of intravasal azoospermia (IVA) and evaluate which factors before and during surgery influence outcome, by prospectively and intentionally performing bilateral vasovasostomies (VVs) only in men with intraoperative IVA. Patients and methods,Using a multilayer technique, 472 men underwent microsurgical reconstructive procedures. Intravasal fluid was examined for sperm by the surgeon and a pathologist. Strict enrolment criteria included total absence of sperm or sperm parts and bilateral VV as a treatment procedure. Patients were followed up by semen analysis and paternity assessed only by naturally conceived pregnancies. Results,Of the 472 patients, 27 (5.7%) had bilateral IVA; 15 of these patients were available for a follow-up of 1,47 months. Eleven patients had identical gross appearance of intravasal fluid bilaterally. Of these patients, five had sperm in the ejaculate after surgery (three with clear intravasal fluid and two with no fluid). Bilaterally different vasal fluid was found in four men. Unilateral clear fluid was present in three patients, two of whom had sperm in semen analysed after VV. Overall, there was sperm in the ejaculate in seven of 15 patients with IVA; five of these seven had clear fluid in at least one vas deferens. One patient with unilaterally clear fluid achieved paternity by a naturally conceived pregnancy. The difference between the mean (sem) obstruction interval in men who had sperm in a semen sample after VV, at 16.7 (3.30) years, and in persistently azoospermic patients, at 15.5 (1.89) years, was not statistically significant (P = 0.741). Conclusion,The results of VV in patients with IVA are unsatisfactory; the patency rate is higher in men with copious clear fluid in at least one vas. The obstructive interval in patients with IVA does not appear to influence the outcome of VV. [source]


Importance of molecular analysis in detecting cervical lymph node metastasis in head and neck squamous cell carcinoma

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 9 2006
Mohamed N. Elsheikh MD
Abstract Background. Because of the impact of nodal status on treatment and survival in squamous cell carcinoma of the head and neck, accurate staging of cervical lymph nodes is critical. This article explores the value of molecular analyses in the detection of cervical lymph node metastasis. Methods. A review of the literature was carried out and combined with our own experience regarding the role of molecular analyses in detecting cervical lymph node metastasis. Results. Few studies have demonstrated the diagnostic and prognostic relevance of molecular analysis in detecting tumor cells in lymph nodes. Nodal staging was improved by the use of molecular techniques; when compared with histopathologic examination, however, the small sample size of these studies did not allow definitive conclusions. Conclusions. Molecular analysis is exquisitely sensitive in detecting very small cancer deposits within lymph nodes. It provides an oncologic basis that may be used to guide therapy and influence outcomes. It should be recommended for diagnostic use in controlled studies of patients without evidence of lymph node metastasis on routine hematoxylin,eosin,stained sections. The clinical significance of these types of metastases, however, must be determined with carefully designed and controlled prospective clinical trials. © 2006 Wiley Periodicals, Inc.

The Influence of Regular Work Systems on Compensation for Contingent Workers

INDUSTRIAL RELATIONS, Issue 4 2003
Article first published online: 16 SEP 200, Brenda A. Lautsch
Using data from a nationally representative survey of U.S. establishments, this article explores how features of regular work influence outcomes for contingent workers. The results show that firms combine regular and contingent work in varied ways: Some managers design contingent work to achieve performance objectives not possible with the regular workforce, whereas managers in other cases create contingent jobs to reinforce the same goals as regular work. In the latter case, contingent workers are more likely to be integrated with regular workers and to receive benefits. Benefit provision for contingent workers is also influenced by traditional internal labor market rules and by spillover effects in which efficiency or regulatory requirements lead benefits to be extended to contingent staff once offered to regular workers.

Substrate and Procedural Predictors of Outcomes After Catheter Ablation for Atrial Fibrillation in Patients with Hypertrophic Cardiomyopathy

JOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 10 2008
T. JARED BUNCH M.D.
Background: Hypertrophic cardiomyopathy (HCM) is often accompanied by atrial fibrillation (AF) due to diastolic dysfunction, elevated left atrial pressure, and enlargement. Although catheter ablation for drug-refractory AF is an effective treatment, the efficacy in HCM remains to be established. Methods: Thirty-three consecutive patients (25 male, age 51 ± 11 years) with HCM underwent pulmonary vein (PV) isolation (n = 8) or wide area circumferential ablation with additional linear ablation (n = 25) for drug-refractory AF. Twelve-lead and 24-hour ambulating ECGs, echocardiograms, event monitor strips, and SF 36 quality of life (QOL) surveys were obtained before ablation and for routine follow-up. Results: Twenty-one (64%) patients had paroxysmal AF and 12 (36%) had persistent/permanent AF for 6.2 ± 5.2 years. The average ejection fraction was 0.63 ± 0.12. The average left atrial volume index was 70 ± 24 mL/m2. Over a follow-up of 1.5 ± 1.2 years, 1-year survival with AF elimination was 62%(Confidence Interval [CI]: 66-84) and with AF control was 75%(CI: 66-84). AF control was less likely in patients with a persistent/chronic AF, larger left atrial volumes, and more advanced diastolic disease. Additional linear ablation may improve outcomes in patient with severe left atrial enlargement and more advanced diastolic dysfunction. Two patients had a periprocedureal TIA, one PV stenosis, and one died after mitral valve replacement from prosthetic valve thrombosis. QOL scores improved from baseline at 3 and 12 months. Conclusion: Outcomes after AF ablation in patients with HCM are favorable. Diastolic dysfunction, left atrial enlargement, and AF subtype influence outcomes. Future studies of rhythm management approaches in HCM patients are required to clarify the optimal clinical approach. [source]


Randomized trial of vein versus dacron patching during carotid endarterectomy

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 4 2001
P. D. Hayes
Background: A recent overview has indicated that, while routine patching is safer than primary closure following carotid endarterectomy (CEA), there is no systematic evidence that patch type influences outcome. Most surgeons perceive that prosthetic patches are more thrombogenic than vein patches. This study tested the hypothesis that it is the patient who is prothrombotic rather than the nature of the patch. Methods: Some 274 patients undergoing 276 CEAs were randomized to either dacron (Du Pont, Stevenage, UK) patch closure (n = 137) or vein patch closure (n = 139). All patients with an accessible cranial window were monitored for 3 h after operation using transcranial Doppler (TCD) ultrasonography. The number and rate of embolizations were quantified, together with the requirement for selective dextran therapy to control high rates of postoperative embolization. All patients were assessed after operation and again at 30 days by a neurologist, and all underwent duplex imaging at 30 days. Results: The 30-day death or any stroke rate was 2·2 per cent for dacron-patched patients and 3·6 per cent for vein-patched patients (P = 0·72). Dacron-patched patients had a higher incidence of postoperative emboli (median 5 (interquartile range 0,10·5)), compared with a median of 3 (interquartile range 1,17) for vein (P = 0·028). However, the incidence of detecting more than 50 emboli was virtually identical and patch type had no effect on the incidence of sustained high-rate embolization requiring dextran therapy (5·3 per cent for dacron versus 3·7 per cent for vein). No patient had a carotid thrombosis at 30 days. Conclusion: Sustained high-rate embolization, previously shown to be highly predictive of progression to carotid thrombosis, appears to be patient dependent rather than related to patch type. © 2001 British Journal of Surgery Society Ltd [source]


Periodontal dressing (Vocopac®) influences outcomes in a two-step treatment procedure

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 4 2005
B. W. Sigusch
Abstract Objectives: It is not clear if periodontal dressing influences the long-term results in a non-surgical treatment procedure. Material and Methods: The periodontal parameters (pre-baseline) of 36 patients with aggressive periodontitis were obtained before the patients were treated initially (1st step) by a dental hygienist, who completely removed the supra- and subgingival concrements. Baseline parameters were raised 3 weeks after the 1st step, before the 2nd therapy step was conducted. It consisted of a non-surgical procedure, which comprised a closed full-mouth manual root curettage (root planing), immediate systemic application of metronidazole, and the placement of a periodontal dressing (Vocopac®, Voco). The patients were randomized to two test groups having their periodontal packs removed after 3,4 days (group 1, n=12) and 7,8 days (group 2, n=12), respectively and a control group (n=12) without periodontal dressing. Clinical parameters were raised again after 6 and 24 months. Results: Six and 24 months later, changes in probing pocket depth (PPD) and probing attachment level (PAL) were observed in all three groups compared with baseline, but the difference was significant in group 2 only. In addition, group 2 showed a greater reduction in mean PPD and also a significantly greater gain of attachment in comparison with the controls. Conclusion: Wound dressing has a positive effect on clinical long-term results using a two-step non-surgical procedure. Moreover, removing the dressing after 7,8 days leads to clearly better results than removing it earlier. [source]
