Selected AbstractsSterile Versus Nonsterile Gloves During Mohs Micrographic Surgery: Infection Rate is not AffectedDERMATOLOGIC SURGERY, Issue 2 2006BRANDON M. RHINEHART MC BACKGROUND: Mohs micrographic surgery (MMS) is an outpatient procedure, which has become the treatment of choice for certain cutaneous malignancies. Although the major steps in this procedure are relatively standardized, one difference involves the use of sterile or nonsterile, clean gloves during the tumor removal phase. OBJECTIVE: This retrospective, chart review study was performed to evaluate whether infection rates are affected by the use of sterile versus nonsterile gloves in the tumor extirpation phase of MMS. METHODS: This study evaluated the surgical records of 1,810 consecutive Mohs patients, of which 1,239 Mohs patients (1,400 Mohs procedures) met inclusion criteria. Age, sex, tumor diagnosis, anatomic location, number of Mohs stages, area of defect, closure type, cartilage exposure, and sterile versus nonsterile glove use were recorded and evaluated. RESULTS: Twenty-five infections were identified. Statistically significant infection rates were discovered for patients with cartilage fenestration with secondary healing and malignant melanoma diagnosis only. There was no statistical difference in infection rates with all other measured variables to include the use of sterile or clean, nonsterile gloves. CONCLUSION: Our study lends support that clean, nonsterile gloves are safe and effective for use in the tumor extirpation phase of MMS, at a significant cost savings. [source] Augmentation of clozapine with a second antipsychotic , a meta-analysis of randomized, placebo-controlled studiesACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2009D. M. Taylor Objective:, Inadequate response to clozapine treatment is frequently encountered in practice and augmentation strategies have been developed in an attempt to improve response. Aims of the study were to evaluate the therapeutic effect of adding an antipsychotic drug to clozapine treatment. Method:, Meta-analysis of randomized, placebo-controlled studies of antipsychotic augmentation of clozapine treatment. Results:, Ten studies (including 522 subjects) met inclusion criteria. Antipsychotic augmentation showed significant benefit over the addition of placebo on only one outcome measure examined [mean effect size for rating scale score (BPRS/PANSS) ,0.180, 95% CI ,0.356 to ,0.004]. Antipsychotic augmentation showed no advantage on withdrawals from trials (risk ratio 1.261, 95% CI 0.679,2.345) or on CGI scores (effect size ,0.661, 95% CI ,1.475 to 0.151). Duration of study was not associated with outcome (P = 0.95). There was no evidence of publication bias. Conclusion:, In studies lasting up to 16 weeks, the addition of an antipsychotic to clozapine treatment has marginal therapeutic benefit. Longer and larger trials are necessary to demonstrate the precise therapeutic utility of antipsychotic co-therapy with clozapine. [source] Comparison of the Medical Priority Dispatch System to an Out-of-hospital Patient Acuity ScoreACADEMIC EMERGENCY MEDICINE, Issue 9 2006Michael J. Feldman MD Abstract Background: Although the Medical Priority Dispatch System (MPDS) is widely used by emergency medical services (EMS) dispatchers to determine dispatch priority, there is little evidence that it reflects patient acuity. The Canadian Triage and Acuity Scale (CTAS) is a standard patient acuity scale widely used by Canadian emergency departments and EMS systems to prioritize patient care requirements. Objectives: To determine the relationship between MPDS dispatch priority and out-of-hospital CTAS. Methods: All emergency calls on a large urban EMS communications database for a one-year period were obtained. Duplicate calls, nonemergency transfers, and canceled calls were excluded. Sensitivity and specificity to detect high-acuity illness, as well as positive predictive value (PPV) and negative predictive value (NPV), were calculated for all protocols. Results: Of 197,882 calls, 102,582 met inclusion criteria. The overall sensitivity of MPDS was 68.2% (95% confidence interval [CI] = 67.8% to 68.5%), with a specificity of 66.2% (95% CI = 65.7% to 66.7%). The most sensitive protocol for detecting high acuity of illness was the breathing-problem protocol, with a sensitivity of 100.0% (95% CI = 99.9% to 100.0%), whereas the most specific protocol was the one for psychiatric problems, with a specificity of 98.1% (95% CI = 97.5% to 98.7%). The cardiac-arrest protocol had the highest PPV (92.6%, 95% CI = 90.3% to 94.3%), whereas the convulsions protocol had the highest NPV (85.9%, 95% CI = 84.5% to 87.2%). The best-performing protocol overall was the cardiac-arrest protocol, and the protocol with the overall poorest performance was the one for unknown problems. Sixteen of the 32 protocols performed no better than chance alone at identifying high-acuity patients. Conclusions: The Medical Priority Dispatch System exhibits at least moderate sensitivity and specificity for detecting high acuity of illness or injury. This performance analysis may be used to identify target protocols for future improvements. [source] Echocardiographic Features of Patients With Heart Failure Who May Benefit From Biventricular PacingECHOCARDIOGRAPHY, Issue 3 2003Amgad N. Makaryus Background: Recent studies suggest that cardiac resynchronization therapy through biventricular pacing (BVP) may be a promising new treatment for patients with advanced congestive heart failure (CHF). This method involves implantation of pacer leads into the right atrium (RA), right ventricle (RV), and coronary sinus (CS) in patients with ventricular dyssynchrony as evidenced by a bundle branch block pattern on electrocardiogram (ECG). Clinical trials are enrolling stable patients with ejection fractions (EF) , 35%, left ventricular end-diastolic diameters (LVIDd) , 54 mm, and QRS duration ,140 msec. We compared echocardiography features of these patients (group 1) with other patients with EF , 35%, LVIDd , 54 mm, and QRS < 140 msec (group 2 = presumably no dyssynchrony). Methods: Nine hundred fifty-one patients with CHF, LVID 54 mm, EF 35% by echocardiography were retrospectively evaluated. One hundred forty-five patients remained after those with primary valvular disease, prior pacing systems, or chronic atrial arrhythmias were excluded. From this group of 145 patients, a subset of 50 randomly selected patients were further studied (25 patients [7 females, 18 males] from group 1, and 25 patients [7 females, 18 males] from group 2). Mean age group 1 = 75 years old, mean age group 2 = 67 years old. Mean QRS group 1 = 161 msec, mean QRS group 2 = 110 msec. Each group was compared for presence of paradoxical septal motion, atrial and ventricular chamber sizes, LV mass, LVEF, and RV systolic function. Results: Of the initial group of 951 patients, 145 (15%) met inclusion criteria. In the substudy, 20/25 (80%) of group l and 7/25 (28%) of group 2 subjects had paradoxical septal motion on echo (Fisher's exact test, P = 0.0005). The t-tests performed on the other echocardiography variables demonstrated no differences in chamber size, function, or LV mass. Conclusions: Cardiac resynchronization therapy with BVP appears to target a relatively small population of our advanced CHF patients (15% or less). Although increasing QRS duration on ECG is associated with more frequent paradoxical septal motion on echo, it is not entirely predictive. Paradoxical septal motion on echo may therefore be more sensitive at identifying patients who respond to BVP. Further prospective studies are needed. (ECHOCARDIOGRAPHY, Volume 20, April 2003) [source] Existential concerns among patients with cancer and interventions to meet them: an integrative literature reviewPSYCHO-ONCOLOGY, Issue 3 2009Ingela Henoch Abstract Objectives: An integrative literature review was undertaken to explore existential concerns among patients with cancer with respect to components, related concepts and targets of interventions. Methods: Comprehensive searches in MEDLINE, CINAHL, PsychINFO, Social Citation Index, SweMed+, Eurethics, NLM Gateway, Faculty of 1000 Medicine, Cochrane Library, EMBACE were undertaken. Each paper was read and classified according to design as descriptive qualitative, descriptive quantitative or interventional. Main themes, interventions and outcomes were identified. Results: The searches yielded a total of 162 articles, of which 109 met inclusion criteria. Existential components from the qualitative studies were divided into two main themes: struggle to maintain self-identity and threats to self-identity. Quantitative studies mainly concerned relationships between existential concerns and other concepts. Interventions and assessed outcomes were consistent with components and relationships found in the descriptive studies. Relationships concerned physical and psychological domains; however, few interventions were evaluated against physical outcomes. No interventions applicable to everyday health-care practice were found. Conclusion: Interventions targeted and evaluated concepts related to existential concerns found in the descriptive studies. Gaps in research on existential concerns in patients with cancer include the need to clarify the concept; how patients' existential well-being may best be supported by health-care professionals in everyday practice; effects of existential interventions on physical symptoms; and stability of results of interventions.

Alex Matthews Two measures of health-related quality of life (HRQOL), the Medical Outcomes Survey Short Form 36 (SF-36) and the Satisfaction with Life Domains Scale for Cancer (SLDS-C), were compared to examine the relationship between health status and life satisfaction among breast cancer survivors (BCSs). A total of 586 BCSs, all of whom were volunteers in peer support programs, met inclusion criteria and completed the self-report measures. Significant correlation coefficients were shown between life satisfaction and measures of health status. SF-36 scores were significantly higher for physical functioning, emotional well-being, and vitality subscales compared to population norms. BCSs expressed greatest dissatisfaction with their sexual ability, physical strength, and bodies in general. Small age differences were found. Results suggest that incorporating multiple measures of HRQOL contribute to the understanding and measurement of the effects of cancer on perceived health status and life satisfaction.

[source] Arthritis self-management education programs: A meta-analysis of the effect on pain and disabilityARTHRITIS & RHEUMATISM, Issue 8 2003Asra Warsi Objective Some reports suggest that education programs help arthritis patients better manage their symptoms and improve function. This review of the published literature was undertaken to assess the effect of such programs on pain and disability. Methods Medline and HealthSTAR were searched for the period 1964,1998. The references of each article were then hand-searched for further publications. Studies were included in the meta-analysis if the intervention contained a self-management education component, a concurrent control group was included, and pain and/or disability were assessed as end points. Two authors reviewed each study. The methodologic attributes and efficacy of the interventions were assessed using a standardized abstraction tool, and the magnitude of the results was converted to a common measure, the effect size. Summary effect sizes were calculated separately for pain and disability. Results The search strategy yielded 35 studies, of which 17 met inclusion criteria. The mean age of study participants was 61 years, and 69% were female. On average, 19% of patients did not complete followup (range 0,53%). The summary effect size was 0.12 for pain (95% confidence interval [95% CI] 0.00, 0.24) and 0.07 for disability (95% CI 0.00, 0.15). Funnel plots indicated no significant evidence of bias toward the publication of studies with findings that showed reductions in pain or disability. Conclusion The summary effect sizes suggest that arthritis self-management education programs result in small reductions in pain and disability. [source] | ||||||||||
