Renormalization Group Therapy

We point out a general problem with the procedures commonly used to obtain improved actions from MCRG decimated configurations. Straightforward measurement of the couplings from the decimated configurations, by one of the known methods, can result into actions that do not correctly reproduce the physics on the undecimated lattice. This is because the decimated configurations are generally not representative of the equilibrium configurations of the assumed form of the effective action at the measured couplings. Curing this involves fine-tuning of the chosen MCRG decimation procedure, which is also dependent on the form assumed for the effective action. We illustrate this in decimation studies of the SU(2) LGT using Swendsen and Double Smeared Blocking decimation procedures. A single-plaquette improved action involving five group representations and free of this pathology is given.Comment: 18 pages, 9 figures, 9 table

Social Skills Group Therapy For Children With Emotional And Behavioral Problems

The topic of this research was the utilization of social skills group therapy with children with poor social skills and emotional and behavioral problems. The literature explains that group therapy has many benefits to clients that are not available in individual work with clients. Social skills group therapy is theorized to be helpful for children with mental health disorders, especially children who are physically aggressive. In this type of group therapy, it is effective to teach children the phases of using social skills and using discussion and role-play to understand each social skill. A social skills therapy group was conducted for eight weeks with six clients between the ages of eight and nine years at Children’s Intensive Services (CIS) in Pawtucket, Rhode Island. The hypothesis of this research was that the social skills group would increase the pro-social behavior of the clients and decrease the anti-social behavior, especially physical aggression. A qualitative analysis was conducted of the group process, as well as a quantitative analysis of a questionnaire sent to the teachers of the group members before and after the group was conducted. Most of the members of the therapy group did at least slightly increase in pro-social behavior and at least slightly decrease in anti-social behavior, although no statistically significant changes were shown. Qualitative reports for the CIS clinicians of the group members show that their social behavior did improve after the group had finished. Not only is educating children about social skills helpful to their social functioning, but it could be used to reduce violence in schools and on a societal level, such as gang violence

Coronary-artery bypass surgery in patients with ischemic cardiomyopathy

BACKGROUND The survival benefit of a strategy of coronary-artery bypass grafting (CABG) added to guideline-directed medical therapy, as compared with medical therapy alone, in patients with coronary artery disease, heart failure, and severe left ventricular systolic dysfunction remains unclear. METHODS From July 2002 to May 2007, a total of 1212 patients with an ejection fraction of 35% or less and coronary artery disease amenable to CABG were randomly assigned to undergo CABG plus medical therapy (CABG group, 610 patients) or medical therapy alone (medical-therapy group, 602 patients). The primary outcome was death from any cause. Major secondary outcomes included death from cardiovascular causes and death from any cause or hospitalization for cardiovascular causes. The median duration of follow-up, including the current extended-follow-up study, was 9.8 years. RESULTS A primary outcome event occurred in 359 patients (58.9%) in the CABG group and in 398 patients (66.1%) in the medical-therapy group (hazard ratio with CABG vs. medical therapy, 0.84; 95% confidence interval [CI], 0.73 to 0.97; P=0.02 by log-rank test). A total of 247 patients (40.5%) in the CABG group and 297 patients (49.3%) in the medical-therapy group died from cardiovascular causes (hazard ratio, 0.79; 95% CI, 0.66 to 0.93; P=0.006 by log-rank test). Death from any cause or hospitalization for cardiovascular causes occurred in 467 patients (76.6%) in the CABG group and in 524 patients (87.0%) in the medical-therapy group (hazard ratio, 0.72; 95% CI, 0.64 to 0.82; P<0.001 by log-rank test). CONCLUSIONS In a cohort of patients with ischemic cardiomyopathy, the rates of death from any cause, death from cardiovascular causes, and death from any cause or hospitalization for cardiovascular causes were significantly lower over 10 years among patients who underwent CABG in addition to receiving medical therapy than among those who received medical therapy alone.

Analysis of rolling group therapy data using conditionally autoregressive priors

Group therapy is a central treatment modality for behavioral health disorders such as alcohol and other drug use (AOD) and depression. Group therapy is often delivered under a rolling (or open) admissions policy, where new clients are continuously enrolled into a group as space permits. Rolling admissions policies result in a complex correlation structure among client outcomes. Despite the ubiquity of rolling admissions in practice, little guidance on the analysis of such data is available. We discuss the limitations of previously proposed approaches in the context of a study that delivered group cognitive behavioral therapy for depression to clients in residential substance abuse treatment. We improve upon previous rolling group analytic approaches by fully modeling the interrelatedness of client depressive symptom scores using a hierarchical Bayesian model that assumes a conditionally autoregressive prior for session-level random effects. We demonstrate improved performance using our method for estimating the variance of model parameters and the enhanced ability to learn about the complex correlation structure among participants in rolling therapy groups. Our approach broadly applies to any group therapy setting where groups have changing client composition. It will lead to more efficient analyses of client-level data and improve the group therapy research community's ability to understand how the dynamics of rolling groups lead to client outcomes.Comment: Published in at http://dx.doi.org/10.1214/10-AOAS434 the Annals of Applied Statistics (http://www.imstat.org/aoas/) by the Institute of Mathematical Statistics (http://www.imstat.org

Medical therapy, percutaneous coronary intervention and prognosis in patients with chronic total occlusions

Objective There is little published data reporting outcomes for those found to have a chronic total coronary occlusion (CTO) that is electively treated medically versus those treated by percutaneous coronary intervention (PCI). We sought to compare long-term clinical outcomes between patients treated by PCI and elective medical therapy in a consecutive cohort of patients with an identified CTO. Methods Patients found to have a CTO on angiography between January 2002 and December 2007 in a single tertiary centre were identified using a dedicated database. Those undergoing CTO PCI and elective medical therapy to the CTO were propensity matched to adjust for baseline clinical and angiographic differences. Results In total, 1957 patients were identified, a CTO was treated by PCI in 405 (20.7%) and medical therapy in 667 (34.1%), 885 (45.2%) patients underwent coronary artery bypass graft surgery. Of those treated by PCI or medical therapy, propensity score matching identified 294 pairs of patients, PCI was successful in 177 patients (60.2%). All-cause mortality at 5 years was 11.6% for CTO PCI and 16.7% for medical therapy HR 0.63 (0.40 to 1.00, p=0.052). The composite of 5-year death or myocardial infarction occurred in 13.9% of the CTO PCI group and 19.6% in the medical therapy group, HR 0.64 (0.42 to 0.99, p=0.043). Among the CTO PCI group, if the CTO was revascularised by any means during the study period, 5-year mortality was 10.6% compared with 18.3% in those not revascularised in the medical therapy group, HR 0.50 (0.28–0.88, p=0.016). Conclusions Revascularisation, but not necessarily PCI of a CTO, is associated with improved long-term survival relative to medical therapy alone

Cognitive behavioral group therapy versus psychoeducational intervention in Parkinson's disease

Objective: The aim of the current study was to evaluate whether cognitive behavioral group therapy has a positive impact on psychiatric, and motor and non-motor symptoms in Parkinson’s disease (PD). Methods: We assigned 20 PD patients with a diagnosis of psychiatric disorder to either a 12-week cognitive behavioral therapy (CBT) group or a psychoeducational protocol. For the neurological examination, we administered the Unified Parkinson’s Disease Rating Scale and the non-motor symptoms scale. The severity of psychiatric symptoms was assessed by means of the Hamilton Depression Rating Scale, the Hamilton Anxiety Rating Scale, the Brief Psychiatric Rating Scale, and the Clinical Global Impressions. Results: Cognitive behavioral group therapy was effective in treating depression and anxiety symptoms as well as reducing the severity of non-motor symptoms in PD patients; whereas, no changes were observed in PD patients treated with the psychoeducational protocol. Conclusion: CBT offered in a group format should be considered in addition to standard drug therapy in PD patient

Latino Acculturative Stress Implications, Psychotherapeutic Processes, and Group Therapy

The Latino population is the fastest growing ethnic minority group in the United States. Yet, Latinos do not receive adequate mental health treatment due to the lack of cultural sensitivity regarding the necessity of bilingual and bicultural staff and culturally modified therapies. The difficulties associated with Latinos wrestling to preserve their native culture while also adjusting to the new dominant U.S. culture may cause them to experience acculturative stress. This specific distress may lead Latinos to implement maladaptive coping strategies that could influence Latino risk factors regarding unemployment, poverty, alcohol and drug abuse, aggressive behavior, mental health issues, and suicide rates. After reviewing the research focused on Latinos, Motivational Interviewing, Cognitive Behavioral Therapy, and Interpersonal Therapy were three major orientations aimed at individual therapy with Latinos while Cognitive Behavioral Group Therapy and psychoeducational groups dominated group therapy literature with Latinos. This review concluded the importance of incorporating cultural values and addressing socio-psychological stressors in therapy in order to produce significant treatment efficacy. Nonetheless, the rapidly increasing Latino population and genuine lack of cultural awareness requires continued research on culturally modifying other treatment modalities, multicultural competency for mental health professionals, and graduate program incorporation of a language component to stimulate interest with this needy population

The Effects of Pre and Post Exercise Low-Level Laser Therapy on Biochemical Markers of Skeletal Muscle Fatigue in Equines

Our objective was to determine whether administering low-level laser therapy before or after exercise had the greatest effect on biochemical markers of skeletal muscle fatigue in equines such as cortisol and blood lactate. Twelve quarter horses were divided into three groups: Group A received no laser therapy, Group B received laser therapy before exercise, and Group C received laser therapy after exercise. A Class II ERCHONIA ® PL500 handheld low-level laser was utilized for treatment with a wavelength of 635nm. Exercise was utilized using a horse walker system for 30 minutes five days a week for three weeks. Blood was collected via jugular venipuncture at time zero and then once a week for the remainder of the study. According to the results of this study, there is no evidence to suggest that laser therapy had a significant effect on equine cortisol or lactate, regardless if it was performed before or after exercise. However, there was an interaction between group and time for both lactate and cortisol. The results also showed that lactate increased as time increased as a result of lactic acid build up due to exercise, and cortisol decreased over time, which could be due to several possible variables such as weather. Several factors could have altered the results of this study, such as age, gender, weather, and diet of the equine subjects

Expression of Green Fluorescence Protein (GFP) in Zebrafish Muscle through Injection: A Gene Therapy Model

Expression of the target gene is important for gene therapy. Presently, localized transgenesis is used for gene therapy which can be achieved by a target gene expression. Here, we have reported the plasmid mediated gene therapy to zebrafish model. For this purpose, we have chosen green fluorescent protein (GFP) as a target gene because the expression can be detected easily. GFP was inserted in a plasmid vector, pQE30 to develop the vector pQE30GFP. The plasmid pQE30GFP was constructed form plasmid, pQE30 and pEGFPC2. pQE30GFP injected directly in one group of fish into the muscle where luciferase expression was noted. In another group, after injection electroporation was performed where we have also noted luciferase expression; but, electroporation cause muscle injury to the zebrafish. In our case, the expression was very strong at the site of injection in first group in compare to electroporation group and in both the cases expression was stable more than two weeks

Characteristics and survival of patients with advanced cancer and p53 mutations.

P53 mutations are associated with invasive tumors in mouse models. We assessed the p53mutations and survival in patients with advanced cancer treated in the Phase I Program. Of 691 tested patients, 273 (39.5%) had p53 mutations. Patients with p53 mutations were older (p<.0001) and had higher numbers of liver metastases (p=.005). P53 mutations were associated with higher numbers of other aberrations; PTEN (p=.0005) and HER2 (p=.003)aberrations were more common in the p53 mutation group. No survival difference was observed between patients with p53 mutations and those with wild-type p53. In patients with wild-type p53 and other aberrations, patients treated with matched-therapy against the additional aberrations had longer survival compared to those treated with non-matched-therapy or those who received no therapy (median survival, 26.0 vs. 11.8 vs. 9.8 months, respectively; p= .0007). Results were confirmed in a multivariate analysis (p= .0002). In the p53 mutation group with additional aberrations, those who received matched-therapy against the additional aberrations had survival similar to those treated with non-matched-therapy or those who received no therapy (p=.15). In conclusion, our results demonstrated resistance to matched-targeted therapy to the other aberrations in patients with p53 mutations and emphasize the need to overcome this resistance
